When the journal has a newer turn, retry `prepareCompaction` with a minimal retained-tail budget; still refuse the checkpoint if both summary inputs remain empty. -- `Session.getEntries()` includes abandoned branches. Synchronization markers must be read from `Session.getBranch()` or a rolled-back partial write can still look committed. -- Child-runtime unit tests load outside Electron. Keep usage accounting behind an injected callback (with a production-only dynamic import) instead of statically importing the Electron-backed singleton into the reusable child registry. -- A compaction model can overflow on the very history it is supposed to summarize. Strip binary images first and map-reduce serialized fragments within a conservative fraction of the model window before the final Pi checkpoint call. -- Renderer-safe truncation markers must be normalized before their length is budgeted, then the truncated value must be sanitized again; NFKC expands `…` to `...` and can otherwise invalidate an exact-length snapshot. -- Packaged builds do not initialize `aiden-dev.log`. Subagent process failures instead write one redacted, owner-only JSONL record to `logs/subagent-runtime.log`; correlate its `SA-*` diagnostic ID, closed stage/code, attempts, timing, and exit status with the Pi journal and V2 run store without logging task or report contents. -- Pi 0.80.10's public `AgentHarness` cannot express Aiden's global sequential-tool policy or resume an already-journaled user tail. Keep the low-level Agent behind `PiAgentRuntimeHarness` until Pi's durable Harness implements restore/resume, tool execution policy, and automatic between-turn compaction. -- Pi's remote model catalog can evolve independently of its agent/session runtime. A full package bump from 0.80.10 exposed breaking Session contracts, so backport the bounded provider-catalog wrapper and any explicitly reviewed transport adapters behind Aiden's registry; do not couple a model-list refresh to an unplanned journal/session migration. -- A provider-scoped catalog refresh must not call Pi's mutating `getAuth()` merely to test configuration: expired OAuth can rotate credentials after the caller's timeout. Use the non-refreshing auth check, resolve staleness before auth, keep provider-owned catalogs out of launch polling, cache valid empty/negative results, and bound HTTP generation timestamps against wall-clock skew so a far-future validator cannot freeze recovery. -- Pi awaits `Agent.subscribe()` listeners. Never register an optional renderer/plugin observer as a critical listener: isolate it through the runtime contribution observer path, or its exception can alter the model lifecycle. -- A Pi observer is not passive merely because its return value is ignored: a live `tool_execution_end` event contains mutable result references, and awaiting the observer blocks Pi settlement. Clone observer events and dispatch them outside Pi's serial lifecycle. -- Global extension tools cannot be copied into a child Agent after authority is minted. Keep child contributions disabled until an adapter can include their names, effects, approvals, schemas, and budgets in the immutable child ceiling. -- Pi's internal idle promise can resolve just before the facade's outer prompt operation classifies hook/subscriber faults. Destructive callers must await both boundaries before reset, deletion, or another prompt. -- A Pi `beforeToolCall` block is non-terminal by default: Pi emits an error tool result and can ask the provider again. If the approval/policy hook itself fails, record the host fault and make the next-turn preparation throw so no second request crosses the broken policy boundary. -- Repair retryable assistants before appending the next visible user or opening its crash-recovery envelope. Once a new user is the leaf, exact failed-assistant abandonment is no longer safe. -- Awaiting only the provider signal does not make session I/O cancellable. Race seed, append, context-build, compaction, and retry hooks against the facade's one managed abort signal, while keeping external effect evidence behind the visible-turn rollback repair. -- Rolling back an inner Pi message transaction can delete a later commit for an enclosing visible-turn envelope while leaving its begin marker. When abandoning a committed failed assistant, re-close only enclosing transactions proven committed on the original branch; never close the current in-flight lease. -- A non-abortable journal append can settle after `app_cancelled`. Track it independently of the managed outcome and quarantine that chat's journal until the write settles and rollback/reconciliation completes; resetting the Agent alone is not a storage barrier. -- Foreground prose aggregates multiple Pi assistant/tool turns, while the durable tail contains only the final assistant. Reconcile that aggregate only when the runtime explicitly reports an abandoned terminal Pi message; doing it before every marker duplicates healthy tool-loop context. -- Electron `utilityProcess` does not provide an owned POSIX process group. Patch Node child-process entry points before provider modules load so Bedrock `credential_process` fails closed instead of spawning an unowned descendant, and bind hard-kill escalation to the captured launch identity rather than a reusable raw PID. -- An effect journal is not crash recovery until its uncertain records change future model context. After Pi rolls back an incomplete visible turn, install an idempotent private no-repeat boundary before accepting another prompt; mark the effect recovery-recorded only after that boundary commits. -- Retry a child worker only when the owned process reports a fast nonzero exit before any inbound IPC. Once a hook, protocol frame, model event, or provider diagnostic exists, retrying is no longer a startup recovery and can duplicate billed or effectful work. -- In an Electron UtilityProcess bootstrap catch, `process.exitCode = 1` does not guarantee settlement because the parent IPC handle can keep the process alive. Flush the bounded stderr marker, then force a nonzero exit on a short fallback timer so main can classify and retry the pre-ready failure. -- Run `oxfmt` only on deliberately reformatted files or isolated hunks: the repository baseline contains legacy formatting, so formatting an otherwise small change can create hundreds of unrelated lines of churn. -- "Safer" compaction checks can be compatibility bugs. Before changing Aiden's Pi adapter, pin the exact upstream commit, hash the relevant sources, and mirror its tests and acceptance behavior—including empty/length summaries and usage-anchor skips—instead of preserving stricter local validators that upstream does not have. -- An Electron E2E teardown deadline must exceed the app's sequential bounded shutdown phases. A 10-second fixture timeout can kill and report a healthy process while foreground, subagent, and packaged-soak drains are still inside their documented 6s + 5s + 5s ceilings. -- Image generation can return a baked checkerboard or an opaque/RGB file even when asked for transparent onboarding art. Inspect the generated pixels, dimensions, and alpha channel before copying it into `renderer/assets/onboarding/`; extract the real background and resample only after visual inspection. -- GitHub release create/edit requests can return HTTP 503 after committing server-side state. Publication must re-read the exact tag, target SHA, draft state, and asset set before retrying or reconciling; never treat an unavailable lookup as a missing release. -- A main-process fallback that reads `settings.lastProviderId` as "the app's last provider" is reading a dead key: the UI persists its real selection in renderer localStorage (`aiden-agent.providerId`/`aiden-agent.model`) and only the Telegram flow ever wrote the settings key. Any main-process consumer (scheduler, tools) must either receive the selection explicitly or have attended chat starts seed the settings fallback. -- A physical XCTest transport spike can keep secrets out of the project and scheme: use a private temporary Derived Data directory, create an injected `.xctestrun` copy beside its `Build/Products` payload, inject an ephemeral canonical pairing-bootstrap JSON into that copy, then use `test-without-building`. Xcode still requires the physical device to remain unlocked through preflight and launch. -- A copied `.xctestrun` resolves `__TESTROOT__` relative to its own location. Keep the injected copy beside `Build/Products` (or deliberately rewrite every relative product path), and derive the advertised LAN address from the default-route interface instead of assuming Wi-Fi is `en0`; otherwise Xcode reports a missing test product or the phone silently times out against a link-local adapter. -- Simulator networking does not prove iOS Local Network privacy readiness. A direct physical LAN request fails as `Local network prohibited` when the host app omits `NSLocalNetworkUsageDescription`; lock both that key and the canonical `NSBonjourServices` value with an XCTest that inspects the built application bundle. -- A newly configured Tailscale Serve HTTPS handler can accept TCP before its tailnet certificate is locally available. Verify/request the node certificate through Tailscale's own CLI, retry the exact path-scoped Serve URL, then remove only that path with matching `--https` and `--set-path ... off`; never use `serve reset` as cleanup. -- Before the first handler exists, `tailscale serve status --json` can be `{}` even when tailnet HTTPS is enabled. Validate the exact normalized node DNS name against `tailscale status --json`'s certificate domains; do not require a pre-existing `TCP.443.HTTPS` listener, and still reject an explicitly incompatible 443 listener. -- Tailscale `--set-path` strips the mounted public prefix before reverse proxying. An Aiden `/api/aiden/v1` mount must target the loopback origin plus the exact same canonical API base, not the origin root; verify `/api/aiden/v1/health` through the real tailnet before claiming transport acceptance. -- `PlistBuddy Add ... string ` can strip JSON quoting when injecting a physical-test pairing payload. Use `plutil -replace ... -string`, compare the injected value's byte count/digest without printing it, and make every secret-bearing xctestrun and payload file owner-only. -- A self-signed `CA:FALSE` TLS leaf cannot be used as an Apple Security trust anchor, and an overlong server-leaf lifetime can fail Apple SSL policy even under a private anchor. Generate an installation-local CA, sign a short-lived `CA:FALSE`/server-auth leaf, present the full chain, anchor only the CA, and pin the leaf SPKI. -- A newly connected physical iPhone can remain an ineligible Xcode destination after pairing until Developer Mode is enabled, the reboot confirmation is accepted, and the phone is unlocked again. Re-read the CoreDevice/Xcode destination list before rebuilding; stale destination errors do not imply a signing failure. -- Foundation and JavaScript do not resolve duplicate JSON object keys the same way. For cross-platform security envelopes, scan raw UTF-8 JSON and reject duplicate keys—including escaped-equivalent names—before either `JSONDecoder` or `JSON.parse`; validating only the decoded object is too late. -- Cross-platform `maxLength` and date parsing need executable shared vectors: Swift `String.count` measures grapheme clusters while OpenAPI/JavaScript limits are Unicode-code-point based, and `ISO8601DateFormatter` accepts forms a strict RFC 3339 parser rejects. Use Unicode scalars for wire bounds and validate the complete timestamp grammar/calendar before constructing `Date`. -- A TTL alone is unsafe when idempotency state is pruned using wall time: after a forward jump and persisted prune, a rollback can make the same key look reusable. Persist a last-observed clock high-water mark with the ledger snapshot and fail closed for new keys until wall time advances beyond it; unresolved in-flight entries still never expire locally. -- Do not retain an unversioned idempotency-array migration path after adding a persisted clock high-water mark: even an empty legacy array is ambiguous and can reopen a pruned operation after rollback. Use an omitted snapshot only for a genuinely fresh ledger and reject every persisted shape that cannot carry the high-water value. -- WHATWG `URL` parsing removes raw and percent-encoded dot segments before exposing `pathname`. Security-sensitive canonical endpoint checks must compare the exact raw path before constructing `URL`, then apply the normal scheme, authority, query, fragment, and normalized-path checks. -- URL libraries also normalize authority bytes: controls may be stripped, Unicode hosts may become punycode, numeric hosts may change form, and padded ports lose their spelling. Cross-platform pairing identity needs a shared conservative raw authority grammar before either Foundation or WHATWG parsing, with the original endpoint string retained for equality checks. -- A `structuredClone`-safe value is not necessarily durable JSON: nested `undefined`, non-finite numbers, `-0`, sparse arrays, accessors, cycles, and nonplain objects can disappear or change. Idempotency results must be recursively validated/cloned into an exact JSON value and tested through `snapshot -> JSON.stringify/parse -> restore -> replay`. -- Entry-count limits alone do not bound durable state. Apply recursive shape limits plus per-result and aggregate serialized-byte budgets before accepting terminal replay data, and give live operation-owner registries an owner-checked terminal release path so the capacity ceiling does not become permanent exhaustion. -- Rork `asc` enables pseudonymous command telemetry by default; use `ASC_TELEMETRY_DISABLED=1` for Aiden operations and `--strict-auth` so stored profiles cannot silently mix with environment credentials. A zero-result app query is only evidence for the active key's scope, not proof of account-wide absence; check product-owned public TestFlight links and reconcile them through the correct account before creating a record. Initial app creation is now `asc web apps create`, requires an authenticated Apple web session, and must remain an explicit owner action. -- `NavigationSplitView` selection can highlight a row without pushing detail on a compact iPhone. Branch explicitly by horizontal size class: use a value-driven `NavigationStack` on compact layouts, retain the split view on regular layouts, and reconcile both selection and path across CRUD and size-class changes. -- Never convert a post-action serialization or snapshot-budget failure into a TTL-bound rejection. The external mutation may already have happened; retain its stable operation reference as an unexpiring unknown/in-flight record until authoritative reconciliation proves a terminal outcome. -- Dependency-injected application services must keep Electron-backed singleton imports type-only. Bind real stores, logging, and platform services in a separate `*-main.ts` module; otherwise focused Node tests load Electron before the pure service can be exercised. -- Web Search existing-auth consent must read Pi's persisted credential store directly. `Models.getAuth()` is not a status-only operation: it can resolve ambient environment credentials and refresh OAuth. Keep the binding service platform-free for tests and bind its owner-only `DataStore`/Pi singletons in `web-search-auth-reuse-main.ts`. -- Local Swift caches should use their own symmetric encoder/decoder rather than the stricter network RFC 3339 decoder. A plain `JSONEncoder` persists `Date` numerically by default, so decoding that file with the wire decoder fails even though the cache is valid. -- Canonical workspace paths can differ textually on macOS (`/var` versus `/private/var`). Managed-worktree authorization must compare the shared realpath-resolved environment identity, not a raw temporary-directory spelling. -- macOS LibreSSL does not support OpenSSL's `-copy_extensions` certificate flag. For an installation-local server leaf, write a bounded temporary extension file with the reviewed SAN/key-usage values and pass it through `-extfile` instead of assuming GNU/OpenSSL CLI parity. -- A private LAN CA cannot satisfy normal iOS server trust from an SPKI fingerprint alone. Keep the leaf pin and carry the installation CA certificate in the locally displayed, versioned pairing envelope so the client can anchor that exact CA before applying hostname, validity, usage, and pin checks. -- A folder-browser selection is not safe merely because its opaque nonce is one-use. Revalidate the approved-root policy, canonical directory identity, and duplicate-workspace state inside the same serialized application-service commit that persists registration; otherwise a root removal or filesystem replacement can win between token consumption and save. -- Durable idempotency must persist the in-flight admission before invoking a workspace mutation and persist the terminal result afterward. A crash between those writes should fail closed as an unknown/in-flight operation rather than allow the same key to execute twice. -- A committed chat append and a started generation are separate durability boundaries. If provider setup fails after the append, return the accepted message with a terminal error stream; if append persistence has an indeterminate outcome, keep the idempotency entry in flight until authoritative reconciliation rather than allowing a duplicate prompt. -- Resumable token streams can produce many events faster than durable storage should be written. Coalesce journal snapshots while preserving monotonic in-memory sequence order, settle the latest snapshot during quit, and close only the revoked device's live responses; an SSE disconnect alone must not cancel server-owned generation. -- An Xcode App Intents localization file reference is not a resource by itself. Adding a missing `AppShortcuts.xcstrings` reference to Copy Bundle Resources makes metadata extraction fail at build-input validation; either provide the real catalog or leave the absent reference out of the shipping resources so extraction and shortcut training use the declared intent phrases. -- After an iOS target rewrite, imported source files can remain in the project navigator without belonging to the shipping target. Verify the active `PBXSourcesBuildPhase` before trusting or testing a configuration/UI file, and make CI compile the renamed scheme for generic hardware when simulator use is prohibited. -- Xcode can also retain unlinked Swift package references and stale `Package.resolved` pins after an imported target is narrowed. Audit the actual target dependency graph, remove unused project package/product references, then keep the resolved pins and bundled third-party notices under the same regression gate. -- `await Activity.update` does not guarantee `activity.content` has already advanced. A Live Activity manager that reduces the next rapid event from that public rendered snapshot can lose semantic transitions. Keep canonical state actor-isolated in the app process, hydrate only when adopting a persisted activity, and test rapid updates on physical hardware before immediate cleanup. -- Separate `xcodebuild test-without-building` invocations normally reinstall an app-hosted XCTest bundle, which removes its Live Activities and invalidates a relaunch-persistence proof. Build and install once, then set `UseDestinationArtifacts` with the destination-relative test bundle for the second phase; verify the first host is gone, keep a cleanup phase, and validate that the CoreDevice UUID and Xcode UDID describe the same physical device. -- A physical XCTest run can pass every test and still print a `devicectl diagnose` collection error while Xcode archives partial diagnostics. Use the XCTest summary and final `TEST EXECUTE SUCCEEDED` result as the gate; treat diagnostic collection as a separate tooling warning rather than a test failure. -- A pairing window can be closed or replaced while durable device issuance is awaiting storage. Rechecking only after issuance is too late because a hidden credential may already exist; pass an exact-session authorization fence into the serialized durable mutation and check it immediately before commit. -- Re-pairing into one fixed Keychain scope makes registry rollback non-atomic because the old credential has already been overwritten. Write each device credential to a versioned scope, durably move the installation-registry pointer, and only then best-effort remove the prior scope. -- CoreDevice and `xcodebuild` can identify the same physical iPhone with different UUIDs. Use `devicectl list devices` only to confirm presence and unlock state, then resolve the actual Xcode destination identifier from `xcodebuild -showdestinations`; passing the CoreDevice UUID directly can report that an otherwise connected phone is unavailable. -- Capability-vocabulary negotiation is not authority. Persist a client's explicit support marker separately from its grants, expose server inventory only to clients that negotiated the additive vocabulary, and require both server support and the exact device grant before enabling the feature. -- Authorizing a classified resource through its full payload reader can leak reconciliation, deletion, or storage state before capability denial. Classify from bounded main-owned metadata first, normalize missing/failed classification at the outer resource boundary, and only then enter payload or effectful services. -- Rewriting a hand-formatted OpenAPI document through a whole-file JSON formatter creates thousands of unrelated diff lines. Preserve its established formatting and make schema changes as narrow patches unless a dedicated formatting migration is intentional. -- A signed high-water file does not prevent rollback when its signing key and authority state live in the same backup domain. Keep the authoritative Bot policy head in an independent macOS Keychain item; use the filesystem head only as a two-phase crash journal, and test restoration of the state, journal, and local key together. -- A durable mutation can become visible before its final lifecycle checkpoint is acknowledged. Reconcile that exact pending operation in the live application service and return the proven committed object; if exact reconciliation fails, fence further mutations until restart instead of letting a retry mint a duplicate identity or chat. -- A capability catalog should not reuse an inventory built for a narrower authority lane. The subagent MCP inventory deliberately excludes stdio and caps servers/tools below the Bot contract; give Bots a fresh inspector over ordinary MCP transports plus their own durable resource and credential incarnations. -- A durable external route and its Bot backing chat live in separate stores, so binding first leaves a crash gap. Reconcile enabled routes under the Bot mutation gate before starting the transport: create only the exact persisted chat id in the managed home, validate existing chat/policy ownership, and durably disable anything that cannot be proven or repaired. -- A soft-disabled external route can be re-enabled by restoring only its older registry file. Bind the complete normalized state digest to an independently protected Keychain generation, but do not simply write either side first: publish `pending(previous,next)`, write the file, then commit `next`; startup may reconcile only an exact previous or next digest. A separate one-way bootstrap marker must prevent anchor loss from accepting the restored file as a fresh baseline. -- Profile reset/delete must invalidate an active Bot bind before waiting for its serialized profile lane, then durably unbind routes before clearing pairing or profile state. Reversing that order can leave an enabled route behind after a partial reset failure. -- Tool-name filtering cannot make an unrestricted shell honor scoped Files access: `run_command` can follow absolute paths, `..`, symlinks, and child-process behavior outside its cwd. Until execution is confined by a sound OS boundary, withhold Custom shell for scoped/off Files and expose it only with the exact Full Mac grant; keep a fresh authority/home/catalog check immediately before every published tool effect. -- A Bot managed-home workspace is intentionally absent from `configStore`, so generic inbound-file storage can mistake its opaque workspace id for a stale ordinary workspace and fall back to a global inbox. Carry the validated Bot identity alongside the backing workspace id, resolve and canonicalize the exact managed home again at storage time, and never allow a Bot-bound failure to enter the ordinary fallback path. -- Ordinary coding tools intentionally allow lazy workspace creation, so their root guard does not pin an inode at assembly. Exact Bot file grants need the same tool factories behind a pinned-root builder; otherwise replacing the entire approved directory between schema publication and execution can silently retarget every routed tool. -- Rebuilding a Bot capability catalog before each effect detects skill drift but cannot interrupt an already-running turn at edit time. Give active Bot turns a separate inventory-generation lease, fence every controlled config/credential publication on both sides, and watch only the exact discovered `SKILL.md` directories admitted into runtime so an external edit aborts immediately without broadly observing the user’s home folder. -- Resource credentials and process credentials intentionally use different fingerprint domains. Join a child MCP process to its grant through a fresh, durable resource/credential incarnation identity while retaining the process fingerprint for execution checks; direct hash equality makes the production join impossible. -- A publication fence is only useful after the new snapshot is synchronously visible to warm readers. Publish the in-memory and disk-cache view first, then advance the inventory generation so a post-fence lease cannot observe stale authority. -- `O_NOFOLLOW` on a Node file open protects only the final component. Replacement-safe writes beneath a mutable Bot home need a native helper that pins the home and every parent with `openat`/`mkdirat`, creates the leaf relative to retained descriptors, and revalidates authority after the write. -- External Bot surfaces must admit the exact protected Bot, chat, audience, provider, and model before appending the user message or consuming a one-shot attachment. Revalidating only at provider dispatch leaves unauthorized durable input behind even when generation is denied. -- A Bot avatar upload needs both bounded container preflight and a real decode/re-encode boundary. Header inspection limits decompression work and rejects MIME confusion; only the independently decoded, center-cropped 512 × 512 PNG may enter the canonical store. -- Once an atomic avatar-manifest rename succeeds, a later directory-fsync error is not a safe rollback signal: deleting the newly named asset would leave a committed manifest dangling. Treat rename as the live publication boundary and let restart validation classify crash durability. -- Do not acquire a paired-device mutation lease before reading a bounded request body. A stalled sender would make revocation wait on attacker-controlled I/O; read and validate the bounded envelope first, then authenticate/acquire immediately before application-service admission. -- Bot capability provider/model IDs are audience-safe opaque selectors, not runtime provider IDs. Resolve them against one fresh main-only catalog snapshot and pass only the exact source identities into chat creation; never persist the opaque selector as runtime configuration or return private catalog resources over Remote. -- A mutation can pass an inventory fence, stage durable Bot policy state, and still publish after the inventory changes. Thread the same `isCurrent` predicate through the final cache-and-disk publication callback so invalidation rejects before either representation becomes visible. -- Favorite ordering spans multiple Bot identities plus one shared ordered list. Acquire Bot mutation gates in stable sorted order before the single process-wide favorites lane, and make desktop archive removal use that same lane, or simultaneous archive/reorder operations can deadlock or resurrect an archived favorite. -- Clearing a submitted mobile draft must be generation-aware: the user can type message B while message A is awaiting acceptance, so A may clear only the exact draft generation it submitted and failures must merge A with the newer text and attachments. -- Durable mobile navigation is not restorable from a chat ID alone. Scope presentation state by the exact installation and paired-device identity, then re-fetch the canonical chat before restoring a path or mutation authority. -- Feature-local Remote clients must forward `credential_revoked` into the coordinator's installation purge path. Handling it only in the main connection loop leaves stale Bot caches and credentials alive after a direct editor or chat request. -- A Bot cache keyed only by Mac instance can expose data from an older phone pairing after re-pair. Include the device identity in its directory, activation token, snapshot validation, and every stale-publication fence. -- Archived Bots may remain identity owners for readable archived conversations even when creation and favorites list only active Bots. Fetch/cache the complete Bot identity projection for inbox validation, then filter archived identities only at actionable controls. -- SwiftUI profile and inbox refreshes can overlap initial tasks, pull-to-refresh, sheet dismissal, and mutations. Fence every assignment and error with a per-load generation, invalidate in-flight loads before mutation, and scope persisted split selection by the exact installation plus paired-device identity. -- A lost create response is still ambiguous when the server returned malformed/truncated success or a mismatched success identity. Retain the exact idempotency key across network, cancellation, invalid-response, 2xx, 408, 429, and 5xx outcomes; unlock an editable draft only after a definite rejection. -- Image Playground's temporary result may be larger than the canonical upload even when it is valid. Bound the system-source admission separately from the normalized output, downsample before full decode, and enforce the smaller transport cap only after metadata-free re-encoding. -- A synchronous copy of a system completion URL creates crash residue before async normalization owns it. Remove only app-owned candidate names at process launch and retry when the editor becomes available because complete file protection can make launch-time cleanup temporarily inaccessible. -- A SwiftUI view hidden with opacity remains mounted and continues running `.task` work. A rollout flag must gate every feature ingress—including cache activation, search, retained-path restoration, deep-link presentation, and mutations—not only navigation or hit testing. -- A per-row canonical-image query can turn a bounded roster into unbounded IPC and renderer memory. Gate roster loads by viewport visibility, cap concurrent reads and retained decoded-byte estimates, prioritize selected surfaces, and ensure an evicted row re-requests when it re-enters the viewport. -- `/usr/bin/security add-generic-password -w` does not reliably consume piped stdin when launched without a controlling terminal; it can print a password prompt and hang until the bounded process timeout. Use `security -i` with a strictly tokenized command and hex value carried only on stdin, then verify the stored value through an independent read. -- Blocking a custom `URLProtocol` handler to stage overlapping responses can serialize the loading queue and make an iOS test look like an app watchdog crash. Defer response delivery without blocking the protocol callback, then release the saved protocol instance after the newer request completes. -- A Messages-like Bot surface becomes ambiguous if a Bot can own multiple writable chats. Treat the Bot identity as the chat identity at every entry point: serialize open-or-create under the Bot mutation gate, recheck after admission, project one deterministic canonical chat, and keep legacy duplicates readable but mutation-blocked. -- Repeated Bot loading can come from overlapping REST refreshes rather than excess SSE. Preserve independently valid cache segments, publish warm state immediately, reuse the active `URLSession`, and reserve animated skeletons for true cold layout loads. -- A provider's generic generation failure can hide a retired saved model. Keep the Bot chat's saved provider/model authoritative, classify the bounded provider diagnostic server-side, and direct the person to Bot Access without exposing raw provider output or silently substituting another model. -- A feature-specific provider catalog can silently diverge from a working chat setup if it reads the portable custom-provider store instead of Aiden's canonical configured-provider inventory. Exercise New Bot against a real built-in provider on a paired physical iPhone, and fence the full durable-to-memory catalog publication so post-refresh leases cannot see stale authority. -- A Full Access Bot policy that omits provider/model leaves the composer or chat metadata as accidental authority. Persist an audience-safe selection plus its exact private binding in the Bot policy, revision and fence every change, atomically rebase only the canonical Custom chat reduction without widening its other grants, and treat chat provider/model fields as a crash-recoverable execution mirror rather than the source of truth. -- A large shared SwiftUI chat body can hit the compiler's type-checking ceiling when a Bot-specific presentation is added inline. Keep the runtime shared, but split transcript, message rows, composer, toolbar, and sheets into bounded view builders so workspace and Bot chrome remain independently readable and compilable. -- Clearing a canonical Bot photo in `onDisappear` defeats both the immutable revision contract and SwiftUI view reuse: ordinary navigation or reconstruction briefly falls back to the semantic avatar and decodes the same bytes again. Keep a bounded decoded-image cache keyed by installation, paired device, Bot, and asset revision; retain the current image across connection-only refreshes and invalidate only when that exact key changes. -- Pi may persist a refreshed OAuth credential during auth resolution. Resolve expired built-in Bot auth before acquiring its inventory lease, then re-read and pin the fresh auth inside the admitted lane; refreshing only after admission invalidates the request's own lease and causes a one-time first-turn failure. -- A Bot configuration save can race a process-wide runtime inventory mutation from provider credentials, MCP configuration, or skill content. Never swallow `BotRuntimeInventoryLeaseInvalidError`: retry the complete snapshot/bind/write transaction under a fresh lease with a small bound, and fail closed without publishing if the inventory keeps changing. -- Bot catalog snapshots embed live facts: credential probes and resource incarnations can legitimately advance their revision after a client loads the editor. Rebase the stale client request onto one fresh audience-scoped snapshot, revalidate every opaque selection against that exact snapshot, and persist only its revision; do not add a second unleased read that can itself race. -- When a capability ships on remote/iOS first (e.g., Edit Bot owning model selection), audit the Mac renderer for the same surface before declaring the feature done. The Mac editor had no access section, no catalog IPC, and no updateBotAccess path; desktop-created bots silently got a main-chosen default model. -- A Remote stream projection reset is followed by a cumulative replacement, not an append-only delta. Reconcile durable chat and clear any feature-local ephemeral accumulator before consuming that replacement; otherwise each reconnect/reset can duplicate the same assistant progress even when the provider emitted every sentence only once. Keep final-answer projection separate from disclosure-only progress so copy, accessibility, completed, and streaming paths agree. -- A successful mobile image upload does not prove the saved model can see it. Project the configured model's image-input capability to the client and revalidate pending attachment kinds before consuming their one-shot handles or appending the turn; otherwise stale or incorrect runtime metadata can silently downgrade an image to a text-only request and prompt misleading filesystem exploration. -- A Compose screen nested inside a parent `Scaffold` can inherit safe-drawing insets a second time, creating a large unexplained gap below the parent's app bar. Make the product shell the single system-inset owner and set nested list scaffolds to `WindowInsets(0, 0, 0, 0)`; likewise, do not add an IME inset when `adjustResize` has already moved the window above the keyboard. -- When more than one adb transport exposes the same Pixel, always select the physical USB serial explicitly for install, launch, UI dump, and screenshots. This avoids deploying to a stale wireless transport or reading UI state from a different device connection. -- A MockWebServer cancellation test for a never-ending SSE response should throttle a response body instead of relying on `setBodyDelay`: delaying only the start can leave the queued body alive and make server shutdown wait even after the production OkHttp call was correctly cancelled. -- Gradle `connectedDebugAndroidTest` can uninstall the debug target package at the end of its managed lifecycle, deleting its app-private Remote pairing credential and caches. For a paired physical device, either use a disposable application ID/device or manually install the already-built target/test APKs and run `am instrument`; always verify pairing state and reinstall the final target afterward. -- A Compose feature screen can miss an in-place pairing transition when its only load trigger is view-owned and navigation immediately changes. Let the lifecycle ViewModel observe the authenticated client plus `CONNECTED` state directly, claim its single-flight marker before launching, and never translate a missing authoritative snapshot into a valid empty account. Server request logs are the fastest way to distinguish “route returned empty” from “route was never called.” -- `windowSoftInputMode` declared on `` does not make a Compose activity an IME-resize owner; a physical device can still resolve it to `adjust=pan` and cover bottom controls. Put the policy on the exact activity, choose one owner (`adjustNothing` plus consumed Compose IME/navigation insets for edge-to-edge), and compare composer bounds against the real IME frame on-device. -- A bounded raw-audio limit is not the HTTP JSON limit: 60 seconds of 16 kHz PCM16 is 1,920,000 raw bytes but 2,560,000 base64 bytes before envelope overhead. Derive and test both boundaries together or the advertised final seconds fail with 413. -- Speech-recognition callbacks can arrive after cancellation/destruction. Fence native callbacks, Mac preparation, capture, and transcription with one monotonically increasing session generation; lifecycle stop must invalidate it before releasing the microphone so an old completion cannot write into a newer draft. -- Codex non-login shells may not inherit either Java or Android SDK discovery even when Android Studio and the SDK are installed. For Gradle verification, point `JAVA_HOME` at Android Studio’s bundled JBR and `ANDROID_HOME` at the configured SDK; do not add machine-local `local.properties` to the repository. -- React Doctor can fail to recognize uncommitted changes in a linked Git worktree and silently fall back to a full-repository scan, even with `--scope changed`. Confirm its scope banner, inspect findings in the actual changed files, and rely on focused tests plus direct diff review rather than treating unrelated full-scan diagnostics as regressions. -- Generic iOS `build-for-testing` can stall in asset-catalog processing in this repository even when the changed Swift sources compile. For a source/test compilation gate, disable signing and exclude `*.xcassets` plus `AppIcon.icon`; keep physical-device behavior and the real signed asset/package build as separate release acceptance. -- A production-profile Playwright run is useful for exercising the packaged policy branch without signing, but it is not evidence about a signed `.app` bundle. Name the gate accurately and keep signed distribution plus physical-device termination APIs as release-environment acceptance rather than silently treating them as local passes. -- When several long-lived mobile branches overlap, do not merge their histories blindly into a release PR. Preserve unique detached commits first, start from a clean `main` worktree, squash the reviewed mobile baseline, then cherry-pick only independently scoped follow-ups; resolve documentation by combining current facts instead of reviving stale build records. -- Electron `utilityProcess.fork` script arguments are delivered to the Node service but may be absent from the packaged macOS Helper command line. Authenticate the loaded worker over its private IPC channel, and reserve `ps` PID/start identity for compare-before-signal cleanup; a smoke that forks the worker directly does not cover production launcher admission. -- A read-only status surface must not merge two independent external snapshots. Tailscale node identity, Serve state, and route classification now come from one bounded command pair; a redundant second inspection can turn one transient CLI failure into a false “Unavailable” state even when the first snapshot was healthy. -- Onboarding dismissal spans a renderer compatibility marker and a main-owned outcome. An explicit provider skip must persist `deferred`, clear any stale selected-provider identity, and teach both launch visibility and the Settings re-entry path that `deferred` is intentionally dismissed but never provider-ready. -- A Tailscale setup failure can originate before Tailscale: production and development Aiden profiles may share a persisted Remote Access port pair. Check the live listeners and per-profile `aiden-remote-v1.json` files first; preserve fail-closed startup and expose relocation only as a confirmed action that cannot orphan an owned or pending Serve route. -- Pi's provider `Context` is structurally typed, so `AgentTool` values with `execute` callbacks can reach a field declared as provider-only `Tool[]`; the agent loop can likewise spread lifecycle callbacks into provider options. Before Electron UtilityProcess IPC, positively project provider-facing tool definitions and documented stream options, then normalize the complete frame to the strict JSON wire contract. -- Generative UI guest HTML is untrusted. Keep iframe `sandbox` at `allow-scripts` only and deny guest `connect-src`. Do not use `iframe srcDoc` in the privileged renderer: Chromium inherits the parent CSP, so guest inline scripts and `aiden-genui:` host libraries never run unless parent `script-src` is widened (forbidden). Serve wrapped HTML from `aiden-genui://preview/` with CSP as a response header and point the iframe `src` at that URL. Host Chart.js/Plotly/KaTeX must load from the allowlisted exact `aiden-genui://` library names or be inlined on export—never from a CDN, and never via a scheme-wide `aiden-genui:` script-src. `protocol.registerSchemesAsPrivileged` has to run before `app.whenReady`. -- A streamed artifact card flickers when its React identity conflates content with position. Keying the card list by content hash made every same-title replace remount the whole chrome, and clearing the iframe `src` before the replacement resolved flashed a placeholder through a fixed-height slot. Key by the stable `mediaId`, fetch first and swap `src` in place, and during the persisted-message reveal window let the live streaming card win while the persisted copy stays hidden so the transition is one atomic swap instead of unmount/remount in two frames. -- An in-chat "Thinking" shimmer can die while the sidebar spinner keeps spinning because the two key off different truths: the sidebar uses stream ownership, the transcript uses content shapes (`!content`, `streamingText.length`). Dropping pi-ai's `toolcall_*` assistant events made the model's longest phase (writing tool-call arguments, e.g. a whole HTML artifact) invisible for every provider; Codex is worst because it often streams no reasoning summaries at all. Consume `toolcall_start` (the partial block carries the final `toolCall.id`, so execution events upgrade the same step), derive the ReasoningBlock's active state from an open thinking step rather than `!content`, and gate "Responding…" on recent text deltas so stale prose cannot pin a static row. -- Sequential `lstat` checks cannot secure a multi-component path against a rename between checks; each accepted ancestor has to remain pinned while the next component opens. For workspace artifact reads, extend the native descriptor-relative helper and test a deterministic mid-walk directory swap instead of relying on timing-sensitive JavaScript races. -- Moving an existing iframe or one of its ancestors between DOM parents can reload its document in Chromium even though React preserves the component identity. Positioning the unchanged host over a portaled modal also fails when transcript `isolate`/`mask-image` stacking contexts trap it below the opaque portal. Promote the unchanged host with the Popover API into Chromium's top layer, override the UA's closed-popover `display:none` plus fixed geometry for its inline state, and browser-test stacking, one-frame count, mutable guest state, small viewports, and Escape relayed from the exact sandbox window. -- A mobile verification shell may know the Android SDK through `android info` while Gradle still lacks both Java and `ANDROID_HOME`. On this workstation, use Android Studio's bundled JBR as `JAVA_HOME` and the SDK path reported by `android info` as `ANDROID_HOME`; do not write a developer-specific `local.properties` into the repository. -- An unscoped desktop chat list includes reserved or stale workspace records in addition to user workspaces. Build a workspace-ID whitelist first and project chats through it; filtering only `botId` is insufficient because the reserved Assistant home and removed-workspace orphans are not Bot chats. -- A unified mobile chat outline can amplify an old transport cost without changing the endpoint: the current global home read carries complete transcripts. Keep the first UI delivery on the compatible read, measure real payload/decode/memory, and treat a bounded paginated summary endpoint as a coordinated server+iOS+Android follow-up rather than silently adding a second background fetch. -- A generic-hardware `xcodebuild build-for-testing` can finish compiling Swift app/test sources and then remain silent in a stuck `ibtoold` finalization pass. Distinguish that local Xcode tooling hang from a Swift compile failure, retain the generic `platform=iOS` destination (never substitute a simulator), and let the clean CI hardware-target compile provide the terminal gate. -- A dictation stop can arrive before microphone or Live-session startup finishes, and a Live transcript can be visible before its finalization handshake succeeds. Latch stop intent by operation identity, keep one wall-clock budget across Live and batch fallback, preserve committed Live text, and ensure cancellation remains callable after audio capture disconnects. -- Release-time and live validators for the same downloaded catalog can drift even when both look strict. Keep one shared acceptance corpus that runs every payload through both validators, including optional display strings and numeric bounds, so packaging cannot emit a snapshot the runtime will reject. -- A post-merge updater should not run dependency installation or repository scripts with `contents: write`. Verify and test under read-only permissions, transfer a hashed artifact, and give only a minimal publish job write access with checkout credentials disabled and the token scoped to its final push command. -- A clean `npm ci` can leave the `electron` package installed without its `dist/Electron.app` payload even when npm reports dependency scripts enabled. Before diagnosing the macOS dev-runtime preparation step, check `node_modules/electron/dist` and rerun Electron's package install script when the payload is absent. -- Computer Use can expose an Electron popover's accessibility tree while returning no screenshot for the open native menu state. Use the fresh accessibility state to verify menu contents and supplement visual-state verification with focused source/tests when pixel capture is unavailable. -- The root working agreement requires consulting and updating `.memory/`, but this PR worktree contains no `.memory` directory or files. Treat current plans, normative protocol docs, source, and tests as the available project history, and call out the missing checkout memory instead of inventing it. -- Parallel server/iOS/Android contract work can briefly diverge on seemingly small constants such as activity vocabulary, cursor bounds, and unknown-field behavior. Freeze those values in one explicit coordinator message before client model tests hard-code them; here the final contract is `idle|active`, 512-character cursors, tolerant harmless additions, and fail-closed required/private fields. -- A cache can satisfy the wire-item bound but still block the UI when every paginated page rewrites one maximum-size aggregate on the main thread. Size the native summary cache against the full 10,000-row contract, move encode/read/fsync work off the UI executor, and commit pagination state only after durable persistence succeeds. -- A connected iPhone is not enough for XCTest acceptance when the local provisioning profile omits the app's App Group entitlement. Keep generic-device `build-for-testing` as the compile gate, report the signing boundary honestly, and rerun device metrics only after `group.sbtbiswas.AidenOnTheGo` is provisioned. -- Adding a derived field to the canonical chat-list projection can leave exact-shape resilience and shipping-source assertions stale even when focused feature tests pass. Search every full-suite assertion over that projection before the first push, and derive expected compatibility values through the production helper rather than duplicating the hash contract. -- The primary checkout can remain on a feature branch whose upstream was deleted, making an otherwise clean hotfix look detached from its delivery path. Check `git status --branch` and worktree registration before editing, then keep diagnosis and verification local unless branch or push authority is explicit. -- A large exact-context documentation patch can fail atomically on one wrapped paragraph. Re-read the numbered lines and retry with the smallest stable context instead of assuming earlier terminal wrapping matches the file. -- `npm ci` reports the aggregate advisory count, which can widen a release hotfix unnecessarily when every finding is development-only. Confirm the shipped graph with `npm audit --omit=dev` before changing dependencies; this hotfix had zero production advisories. - -## Packaged Electron consent acceptance without a shipped bypass - -Artifact-level diagnostics acceptance needs to exercise renderer ownership, -preload IPC, the main handler, and `crashReporter.start()` while a native -confirmation is waiting for input. Do not compile an environment-variable -consent bypass into customer builds. Launch the disposable packaged process -with a loopback Chromium debugging port, invoke the public action through the -real preload bridge, use System Events to click the real native button by its -exact accessibility label, and verify a post-start diagnostic event plus -`uploadToServer: false`. - -## Pi journal promotion recovery - -A promoted v4 journal may legitimately retain a `.v3-backup` after its migration -receipt is lost in a crash window. Recovery must inspect the authoritative journal -header before choosing a decoder: decode the backup as v3 and the live journal as -v4. Treating every backup-bearing path as v3 makes the next packaged restart fail -on the already-promoted v4 header. - -## Stacked release worktree setup - -An execution command cannot start with a workdir that the same command is meant -to create. Add the detached worktree from an existing checkout first, then run -stack assembly inside it. - -A fresh `npm ci` installs Playwright's package but not its Chromium binary, so -the full suite stops at Generative UI containment before assertions run. Mirror -CI with `npx playwright install chromium` before the first full local gate. - -## Hosted MCP OAuth verification - -The Dropbox origin-level protected-resource endpoint can return 429 while the -resource-path endpoint advertised by `WWW-Authenticate` succeeds. Verify hosted -MCP setup through that advertised RFC 9728 URL and the SDK's DCR redirect flow. - -## Release preflight environment - -`npm run release:preflight` intentionally fails outside the release runner when -Apple notarization credentials are absent. Treat local consumer/branding tests -as code gates and the credentialed GitHub release job as the signing gate. - -## Cross-client global settings - -Remote has feature-specific settings routes but no general settings contract. -An authoritative global preference therefore needs a narrow server-owned -endpoint; storing it only in iOS or Android would not change Mac agent behavior. - -## Worktree verification dependencies - -This worktree has no local `node_modules`; `npm run type-check` initially fails -with `tsc: command not found`, so verification needs the bundled runtime or a -dependency install before TypeScript suites can run. - -Android Gradle also does not discover the installed SDK in this worktree; -verification needs `ANDROID_HOME=/Users/sambitbiswas/Library/Android/sdk`. - -The full iOS `AidenRemoteClientTests` target currently has two unrelated -failures in chat-summary/private-child validation; focused memory tests are -needed to separate this change from that baseline noise. -- Verification initially referenced a guessed OpenAPI path; the canonical files are under `protocol/aiden-remote/v1/`. -- Focused Android tests need Android Studio's bundled JDK because this shell has no default Java runtime. -- URLProtocol request bodies can arrive through `httpBodyStream`; iOS request tests must use the existing `bodyData` helper. -- In zsh, a loop variable named `path` overwrites the executable search path; file-by-file commit scripts must use a non-reserved name. -- Parallel `xcodebuild` invocations share DerivedData and can lock `build.db`; run simulator build and test gates sequentially or isolate derived-data paths. -- New focused tests can pass locally yet be absent from `npm test`; register every new test script in the CI entry chain. -- Revision checks around settings writes need an explicit serialized lane; async read-then-write alone permits stale concurrent mutations. -- Backticks in `gh api -f body=...` are evaluated by zsh before submission; use single-quoted plain text or standard input for review replies. -- A merged feature does not auto-increment releases; bump both package manifests before merging when the current tag already exists. - -## Codex-hosted UI reference work - -Codex blocks Computer Use from automating its own `com.openai.codex` host. Use -the supplied screenshot and inspect the installed app bundle for behavior and -styling evidence instead of treating self-host automation as available. - -A fresh linked worktree can lack `node_modules`: `npx` may fetch `tsx`, but -React-backed renderer tests still fail to load. Run `npm ci` before the focused -Quick View and Environment verification gates. - -In this linked worktree, `npm ci` installed the Electron package without its -`dist/Electron.app` payload, so `npm run dev` reached Vite but failed in the -macOS runtime preparation `lipo` step. Run Electron's package installer before -attempting dev-app visual acceptance. - -The project instructions reference a `.memory/` folder, but this linked -worktree does not contain one. Use the repository plan and UI reference docs as -the local source of truth, and record the missing folder rather than inventing -project history. - -Adding or changing exports in the Environment or Terminal providers makes Vite -invalidate Fast Refresh and remount the renderer. An open terminal can then -briefly reference a main-process session that the remounted provider no longer -owns; reopen the terminal before judging the final live state. -- Source-regex coverage made the first Quick View split look independent even though both controls still shared one `open + tab` state. Add reducer transition coverage whenever two UI routes are meant to coexist. -- Simultaneous right-edge surfaces need measured workbench geometry, not window breakpoints; the app sidebar changes the available allocation without changing the window width. -- Final dev-window automation was unavailable while macOS was locked; the renderer and Electron process launched, but visual acceptance still requires an unlocked desktop. -- The deterministic Electron E2E still targeted the retired Environment summary role after the toolbar controls split. Floating surfaces can also cover their toolbar triggers, so smoke tests must use the visible surface-local Show Quick View and Close controls while verifying the toolbar state changes behind them. - -- 2026-09-04: A mounted live-region test with only floating/pinned panels missed Quick View covering an open tools panel. Exercise inert/aria-hidden containment and persistent DOM identity in real Electron, plus message updates while the sibling panel is hidden. - -- 2026-09-04: The diagnostics forged-record fixture aged past journal retention, so export pruned it before the rejection assertion. Use current timestamps for validation fixtures; keep fixed clocks for explicit retention tests. - -## Design audit evidence (2026-09-04) - -- The original standalone report copied palette values and hand-entered ratios, so runtime contrast fixes did not update its matrix. Generate measurements from the current appearance resolver and label compositing assumptions explicitly. -- The original report verification scripts logged failed checks without setting a failing process exit code. A successful command exit alone did not establish that their assertions passed; use enforceable assertions rather than console-only checks. -- Source-contract tests establish selected implementation rules, not rendered accessibility or full workflow coverage. Keep measured contrast, Electron interaction checks, and manual acceptance distinct. -- Archive untracked audit documents before a substantial rewrite: Git cannot restore their earlier contents. This run replaced the old `docs/DESIGN.md` with a scoped current reference; a complete original was not recoverable, so no purported historical archive was created. - -- 2026-09-04: Full verification exposed a diagnostics fixture timestamp fixed to August 27; after journal retention elapsed, export correctly pruned it before the rejection assertion. Forged-record fixtures now use the current timestamp so the tests exercise validation instead of aging out. - -- 2026-09-04: Tailwind 4 emits individual `scale` for scale utilities; transitioning/resetting only `transform` does not cover press feedback. Transition and reset the emitted property explicitly, including both reduced-motion sources. - -- 2026-09-04: Electron CI intermittently retained the scheduled-task query after Playwright selectText + Backspace, then passed on retry. Reset this exploratory filter with fill("") while retaining input-value and result assertions; keyboard focus/navigation regressions remain separate. Completed-job REST logs were available before gh run view exposed whole-run logs. - -- 2026-09-04: Substring selector edits can match the tail of a compound focus selector and strand base geometry in focus-only styles. Anchor standalone-selector assertions and measure resting preview boxes in Electron; computed colors alone do not prove that a preview renders. - -## 2026-09-04 — pi-vcc integration - -- The clone has an MIT declaration in README but no separate license file; - retain that attribution and full MIT terms in packaged THIRD_PARTY_NOTICES. -- pi-vcc assumes numeric references and legacy retained IDs. Adapt its pure - compiler; use v4 canonical active lineage and fail on an unprovable tail cut. - Unknown/LLM summary-only gaps must bypass its format-specific merge parser. -- Vendor typing needs Intl.Segmenter typings and optional isWordLike; intentional - control-byte regexes need a narrow lint exception, not broad lint suppression. -- Package verifier tests must realpath macOS temporary directories because /var - is a symlink to /private/var and the production verifier rejects symlink paths. -- Android focused tests require Android Studio's bundled JDK plus ANDROID_HOME. - iOS activity tests were run on physical iPhone 13 Pro, not a simulator. -- React Doctor's deprecated --diff invocation scanned the whole repository and - reported existing ref-in-render/cleanup diagnostics outside this feature; - TypeScript, ESLint and feature suites are tracked separately. -- Packaged Settings acceptance must seed profile readiness with profile:setName - and app:setOnboardingProgress before deferring onboarding; settings:set ignores - profile fields. Wait for and click the Settings button instead of racing the - initial keyboard-command listener. -- PR review found cancellation coupled to the legacy status string. Use explicit - compaction activity, and exercise engine override commands with IPC held open - in Electron so fast local completion cannot hide the regression. -- Worker errors must preserve bounded, known causes without relaying arbitrary - exceptions that could include history. Fixed codes allow operation-specific - recall copy; Object.hasOwn is unavailable in this project's TypeScript lib. - -## 2026-09-05 — 0.38.1 release signing - -- Main CI passed, but the macOS release failed at security set-key-partition-list. - app-builder-lib 26.15.3 incorrectly passes the certificate import password to - unlock the temporary keychain. Upstream #10101 fixes this; stable v26 packages - inspected through 26.16.0 still carry the old code. Keep the existing lockfile - and apply the narrow version/source-guarded postinstall backport, with a - platform-independent test that exercises both certificate and keychain paths. -- A changelog search conflated the stable and prerelease lines. Verify published - package code before assuming a release contains the upstream patch. -- The environment-browser checkout has no `.memory/` directory despite AGENTS guidance; use current source, existing design references, and the scoped browser parity document as implementation evidence. -- t3code's browser spans profiles/import, recording, annotations, device emulation, and agent control across desktop/server/web. Track a source-backed feature matrix before porting; a navigation-only webview would silently miss the requested parity. -- `npm ci` completed without Electron's macOS payload in this worktree; `node node_modules/electron/install.js` restored `Electron.app` before UI testing. -- T3's hardcoded `source3` Playwright extraction points at a different bundle string in installed Playwright 1.62.1; locate the named generated module to preserve selector-engine parity. -- Generated onboarding art had real alpha but a 1254px canvas despite the requested 1024px; normalize the final PNG to the repository's exact 1024px contract and validate its alpha. -- System `java_home` has no registered JDK, but Android Studio's bundled JBR works for Gradle; use its `Contents/jbr/Contents/Home` and the existing Android SDK explicitly for focused mobile tests. -- No physical iOS device is connected for this run, and repository guidance prohibits simulators. Generic iOS `build-for-testing` with signing disabled compiles the app/tests; actual XCTest execution remains a physical-device check. -- Electron 43 emits the console-message payload on the event object; reading the legacy second argument as that payload threw during first navigation and blocked the test app behind an exception dialog. Use the current typed event and verify in real Electron, not just service mocks. - -- 2026-09-07: Native Browser views sit above renderer menus/dialogs. Presentation now observes visible overlays and serializes tab show/hide across remounts so delayed cleanup cannot hide the replacement view. -- Renderer-only Playwright captures omit native WebContentsViews; use the exact worktree Electron.app with CUA for visual proof. Several installed Electron copies share a bundle ID, so resolve the full app path. -- Streaming reveal briefly renders duplicate final message text; E2E assertions must target the visible transcript occurrence and independently check the scripted tool scenario completed. -- Browser preflight exposed two existing source-contract mismatches in unchanged provider badges and button press-feedback tests. Keep that baseline distinct from browser regression results. -- Responsive emulation letterboxes inside the native slot. Crop captures to the rendered viewport before translating annotation coordinates; using the full slot silently distorts vertical selections. - -## 2026-09-07 — Browser integration verification - -- Floating placement measured the workbench wrapper and covered the Environment close control. Measure the chat viewport and visible side surfaces; retain a normal pointer-click regression. -- Approval summaries and tool admission both use browser policy helpers. Full-mode E2E misses Ask-mode summary errors; retain TypeScript validation and an actual approval-loop regression. -- Reverting live styles during the preview debounce must still enqueue the restored desired state; comparing only the last completed key leaves an in-flight change applied. -- Native visual verification exposed empty-chat composer overlap and CDP visible-size ownership. Reserve every composer and use `dontSetVisibleSize` so device emulation cannot override the measured native slot. -- Browser tab titles and renderer selection can lag the main state response. E2E waits for `aria-selected`, closes the intended row, and canonicalizes URLs when finding the native guest. -- Launching the shared Dev profile hit existing artifact/history recovery errors. Browser testing uses `build/browser-dev-profile/` with separate portable/user-data roots, copied provider setup, and a fresh workspace history. -- Live browser test: agent tried `browser_open(file:///tmp/sample.html)` and received HTTP(S)-only rejection, then recovered with a Python server serving all of `/tmp` on port 8899. UI workspace `open_file` is not exposed to agent tools; add explicit local-preview guidance and a bounded file-preview route through existing tools, including intentional handling of user-requested files outside the workspace and server cleanup. - -## Browser lifecycle and progressive disclosure — 2026-09-08 -- An agent-created Python preview outlived its document. Verified the exact task-owned PID/start/cwd/port, terminated it, confirmed the HTML was absent, and removed its log. Managed exact-file previews now replace that fallback. -- Review found queued actions could resume after human takeover, approvals could outlive page identity, and hover overlays could intercept semantic clicks. Added focused regression coverage and fixes. A cursor-cleanup review incorrectly read evaluate's isolated-world argument; the live cursor test caught the regression, and cleanup was restored to the creation context. -- Progressive disclosure must install executable tools and update both outbound and durable-compaction budgets at a turn boundary. A setup-return wiring mistake was caught by TypeScript/review before Electron validation. -- `tsx -e` uses CommonJS here and cannot load Pi's ESM-only export; use `node --import tsx --input-type=module` for measurement scripts. -- Host preparation runs after a tool turn, and Pi journals an aborted assistant on Stop. Cancellation tests must reach that boundary and preserve its journal record; an abort rejection must not become a policy fault, while an independent host failure must still fail closed. - -- Electron main-process evaluation cannot dynamically import a module from the Playwright utility world. The delayed-acquisition regression uses `process.getBuiltinModule` and synchronizes builtin ESM exports so its filesystem gate actually reaches the production namespace import; restored in test cleanup. -- Final dev restart exposed Browser mounting with a fabricated default workspace while workspace data loaded. Mount it only after the selected workspace exists; verify cold startup and the existing Environment/browser integration suites. - -## PR99 hosted CI follow-up — 2026-09-08 -- Diagnostics source scanning treated console calls in the serialized Playwright guest runtime as executable main-process logging. Use syntax-aware scanning with regression cases, retaining the reviewed-sink boundary. -- Hosted CDP returned redacted object keys in a different order; the test incorrectly tied collision suffixes to boolean values. Verify distinct sanitized keys and preservation of both values without relying on enumeration order. - -- Pullfrog identified silent sensitive guest permissions and a workspace-wide local-preview origin. Restrict guest grants and serve exact pinned document/asset sets with distinct origins; keep declared workspace-file authorization while blocking unrelated siblings. -- Ad-hoc `tsx -e` selected CommonJS and rejected the ESM-only Pi package exports. Use `node --import tsx --input-type=module` for token-estimate probes. -- Matching-first input probing showed Chromium suppresses the duplicate injected keyDown, so a timing-only expectation could swallow the only physical event. Use Electron's native debugger-source flag for keyboard input, and interrupt unexpected repeats. Mouse-down/up omit this flag and retain a bounded documented collision fallback. -- The next hosted Electron gate exposed immediate recording stop before the encoder produced a frame (both attempts). Validate recorder readiness instead of weakening the WebM assertion. Completed-job logs during an active run require the jobs/logs API; gh run view waits for whole-run completion. -- Independent Chromium reproduction showed per-port preview cookies leaked to other localhost ports because cookies ignore ports. Replace cookies with native frame/origin-scoped request authorization, strip inherited headers and legacy cookies, and test redirects against a controlled server. - -## PR99 direct-preview follow-up — 2026-09-08 -- Exact-grant hardening left path-only Files/chat/terminal previews unable to load local sidecars. Derive a bounded static resource set for user-originated opens only, preserve strict explicit agent grants, and test the actual path-only entry point. -- Static-discovery review found a sidecar symlink could target an excluded HTML/PDF, and same-content rewrites could reuse an older modification-time fingerprint. Reject canonical document targets and include pinned source metadata in grant identity. - -## 2026-09-04 — Queued composer controls - -- Pi harness queueSteer/queueFollowUp are not exposed through the foreground durable transcript path. Use Stop, a persistence barrier, and normal append for desktop Steer. -- E2E TypeScript uses an older lib target; use reverse/find rather than Array.at in new test helpers. -- Appearance persistence uses the `settings` envelope in settings.json; verify the preference from that envelope after relaunch. -- Queue removal confirms durable append, not provider receipt. Wait for the exact provider request before asserting conversation history. -- Joined actions need explicit square inner seams, shared outer squircle radii, visible focus overflow, and observable hover/focus tests. - -## 2026-09-06 — Settings and global Skills verification - -- Responsive Model Pad sizing must use the actual Settings scrollport and account for titles, controls, axes, legends, zoom, and scroll position. -- Gate both skill inventory readers before and after asynchronous discovery, and recheck at execution time; disabled projection must cover inference, compaction, recall, Telegram queues, and every Bot catalog/edit surface. -- Keep full tests and production builds sequential in one checkout because both build native helpers and concurrent runs can race over universal binaries. -- Route Bot-scoped catalog identity end to end and isolate per-Bot iOS caches; Android has no persistent catalog cache. - -## 2026-09-08 — 0.39.0 four-PR integration - -- Zsh does not split scalar loop values by default; use explicit delimiters in pairwise merge probes so branch names are not accidentally concatenated. -- Standalone green PRs still conflicted in shared settings, test registries, and UI fixtures. Assemble the exact combined stack and retain every feature's test registration before merging to main. -- UX review (2026-09-05): the active Xcode installation rejects tools until its license is accepted. Git and desktop C helpers can use the separately installed Command Line Tools via `DEVELOPER_DIR=/Library/Developer/CommandLineTools`; helper build scripts replace the child environment, so this run compiled their unchanged C sources with the same flags directly. iOS physical-device discovery/test remains blocked; do not claim it passed. -- Electron E2E failure diagnostics called `app.process()` outside their try/catch; a closed Electron target hid the original launch error. Keep that call within the best-effort diagnostic block. The isolated E2E profile also cannot establish native Bot Keychain authority; the editor test injects a test-owned IPC catalog and captures the submitted access, while storage/authority tests run separately. - -## 2026-09-10 — Google catalog PR validation - -The main checkout's shared node_modules matched Pi's pinned version but lacked -postcss-value-parser and @xterm/addon-web-links required by this worktree. The -resulting type errors disappeared after replacing the temporary dependency -symlink with this checkout's own npm ci. Full type-check and lint then passed. - -## 2026-09-09 — Draft chat planning - -- The checkout has no `.memory/` directory despite AGENTS.md referencing it; used current source and the plan index for project context. -- Native verification: no physical iOS device is online and local Java/Android SDK tools are unavailable. Run generic iOS build-for-testing and shared Remote contract suites; device XCTest and Android runtime acceptance remain unavailable locally. -- Draft lifecycle regression tests intercepted `chats:appendMessage` for first-send failures; updated that fault injection to the new atomic `chats:createWithFirstMessage` boundary. -- Empty-chat migration must distinguish header-only Pi journals (created by the old Todo snapshot read even before Send) from real private records; preserving every journal would leave ordinary abandoned chats behind. -- Completed Pi v3-to-v4 promotion adds lane/navigation records even for a header-only source. Empty cleanup must validate the real receipt, backup digest, and exact migration scaffolding rather than treating all promoted records as user history. - -## 2026-09-10 — PR #102 readiness - -- The initial source-scanning theory incorrectly credited explicit 1x encode arguments that are already Electron's defaults. Exercise the actual fix with a valid oversized PNG through `providers:save`, relaunch, and verify the recovered, decodable 64px-or-smaller result. -- Treat user-supplied provider PNGs as original-color artwork; an alpha mask turns fully opaque icons into solid squares and disagrees with native clients. -- Model Pad animation settling must ignore infinite animations and retain a bounded timeout so hosted Electron runs cannot wait forever. -- The cold hosted responsive matrix can reach its last 390px case only as the shared 90-second test budget expires, while a warm retry passes in 24 seconds.

Startup can call `resumeRecoverable()` to resume nonterminal records idempotently.

They must not shell out directly; Git and worktree work stays behind existing application services. + +## Production effect integration + +`DesignHandoffEffectStore` owns a second owner-only, bounded ledger, `design-handoff-effects.json`. The coordinator journal records the cross-store state machine; this effect ledger records the operation-keyed identities needed to rediscover effects after a crash. It stores only workspace/chat/task IDs, renderer-safe labels, the parsed handoff packet, and the published linkage. It does not store repository paths, source bytes, prompts, credentials, Git capabilities, or tool authority. + +The existing managed-worktree and chat application services do not accept a caller-owned effect ID. The production adapter therefore derives a deterministic `feature/design-handoff-` branch and a visible `Design handoff · ` chat title from the operation ID. Before creating either effect it searches authoritative main-owned records for that tag. The effect ledger then binds the discovered/generated workspace and chat identities to the operation. An ambiguous discovery fails closed. + +Managed target inspection pairs the current Review snapshot with the cohesive committed Git `HEAD`. `verifyTarget` repeats that inspection immediately before any effect and requires the exact preview, dirty state, and commit the person confirmed.

A new managed handoff workspace is changed to `ask` permission before chat creation, so ordinary source writes and shell work retain Aiden's approval gates.

The library may derive a user-facing Prototype, Connected App, or combined filter from connection state plus canvas contents without persisting `mixed`. Every canvas node records its canonical data source independently as `generated-artifact`, `connected-app`, or `reference-asset`. Connected source access continues to require the existing workspace authorization and stale-snapshot checks. Full permission never bypasses Designer Action review. + +### Artboard lineage + +Artifact titles are display metadata and must not define history. Each generated artboard node owns: + +- a stable `lineageId`; +- an ordered, bounded `artifactMediaIds` history; +- an `activeMediaId` that must be a member of that history. + +Artifact media IDs may belong to only one lineage and one project. Rename, new revision, selection, history comparison, and export use lineage identity rather than title. Duplicate creates new node and lineage IDs while remapping every immutable artifact revision. + +Generated revisions cross three durable stores through a main-owned publication protocol. The Generative UI record stages validated `{ projectId, lineageId }` ownership beside the immutable media ID. A selected-artboard revision additionally records its exact active base media ID; a new-artboard lineage and node ID are deterministic hashes of project and media identity. The renderer never supplies or reconstructs this ownership from a title. + +During generation the record remains a candidate. Only a successfully completed terminal turn marks it eligible before the assistant-message append. An explicit user stop with partial Design output keeps the live preview open and asks the owning desktop renderer to choose **Keep draft** or **Discard** before terminal persistence: Keep crosses the same eligibility barrier as successful output, while Discard omits the descriptors and exact-deletes the staged rows. Dismissed prompts, failed turns, headless clients, and non-user cancellations (deletion, authority changes, scheduled cancellation, or shutdown) take the discard path without blocking for UI. After an eligible descriptor is durable, main commits the blob, atomically appends it to the project lineage, advances `activeMediaId`, and marks the ownership published. Interrupted or incomplete candidates are discarded during Design reconciliation and are excluded from generic HTML-artifact recovery. A selected revision uses semantic compare-and-swap: if its exact base is no longer active, publication fails without replacing the newer active revision. + +Startup recovery inspects Design-owned records before generic interrupted-artifact recovery. It publishes an eligible record only when the exact full artifact descriptor—including content ID, media ID, title, MIME type, byte size, and revision parent—is already present in a durable assistant message; an uncommitted eligible record without that proof is discarded, while an anomalous committed record remains suppressed. A cleanup write with an ambiguous result is safe because restart discards any remaining candidate or suppressed row using its persisted generation identity. A crash after project publication but before the final marker is safe because replay recognizes an already-owned media ID and never rolls a lineage back from a newer active revision. Generic recovery handles only records without Design ownership. Legacy artifact records without ownership fields remain readable, and legacy chat migration installs their conservative project ownership as described below. + +### Persistence and bounds + +Main owns `design-projects.json` under Electron `userData`. The `DataStore` writes it atomically with mode `0600`, rejects corrupt or unsupported input, detects external replacement, and refuses writes while the original file is unsafe. Renderer state is never authoritative. + +The V1 schema has exact keys and explicit ceilings for: + +- projects and store bytes; +- nodes and artifact revisions per artboard; +- reference-asset IDs; +- title characters and bytes; +- opaque ID lengths; +- finite canvas coordinates and millipixel normalization; +- per-project serialized bytes. + +The snapshot has no fields for source code, HTML, prompts, base64 data, absolute paths, capabilities, credentials, process IDs, temporary URLs, or source-selection handles. References are bounded opaque IDs using a path-ineligible alphabet. + +Every mutation is compare-and-swap against the project revision. A successful change increments the revision and writes a monotonic timestamp. A stale caller receives the current revision and cannot overwrite the newer project. + +### Migration + +Opening a legacy `/design/$chatId` route asks an injected main-owned adapter for bounded facts about that chat and its committed `design:` artifacts. Missing/deleted chats do not create projects. An unreadable artifact store or malformed facts block migration without replacing either source store. + +Legacy storage has no stable lineage fact. Migration therefore never groups by artifact title: each committed artifact becomes one conservative artboard and one explicit lineage. This may initially show multiple artboards that the old renderer grouped by same-title display text, but it cannot silently invent a false revision history. + +- project ID is a deterministic hash of the chat ID; +- node and lineage IDs are deterministic hashes of that artifact's media ID; +- the lineage history contains only that proven media ID and it is active; +- desktop positions reproduce the shipped 1,200 px artboard plus 120 px gap. + +The installation is a single atomic project-store mutation that rechecks chat ownership. Concurrent or interrupted first opens therefore converge on one project. A later migration version may merge lineages only if a legacy source gains a stable lineage identifier; titles remain display metadata. + +### Copy and deletion + +Project copy is a preparation protocol. An injected main-owned coordinator first prepares the target chat plus immutable artifact and asset copies, returning complete old-to-new ID mappings and a scoped rollback. The project row is installed only if the source revision is still current and every reference is mapped. A failed installation invokes rollback. + +Deletion is deliberately split: + +1. the store produces an exact project- and database-revision-bound cascade plan covering the chat, every artifact in every lineage, reference assets detached from the project, reference assets that become globally unreferenced, and injected comment/action IDs; +2. a future main-owned recoverable coordinator durably journals and executes cross-store deletion; +3. the project-store delete primitive removes only the project row and returns the same plan. + +The coordinator journals the exact plan before asking the store to consume it.

The ordinary chat removal handler should use +`routeChatDeletion`; it must return the confirmation-required payload to the +renderer instead of translating it into a generic delete failure. + +Use `createIdempotentDesignProjectChatDelete({ chats: chatStore, application: +chatApplicationService })` for the cascade's chat callback. It avoids turning a +restart after the chat payload was already removed into a false recovery +failure while still routing an existing chat through all private-store cleanup. diff --git a/docs/architecture/design-source-adapters.md b/docs/architecture/design-source-adapters.md new file mode 100644 index 00000000..da56b23f --- /dev/null +++ b/docs/architecture/design-source-adapters.md @@ -0,0 +1,123 @@ +# Design Source Adapters + +Status: Implemented for the supported Vite/React and bounded Next.js fixtures. Main-generated +source graphs, header-bound preview capability transport, HMR containment, and packaged acceptance +are complete; unsupported source shapes fail closed. + +## Boundary + +Design source adapters translate an observed preview element into a reviewable workspace source +range. They do not grant file, command, network, process, Git, or mutation authority. A selection is +usable only when main can prove all three identities at the same time: + +1. the exact runtime instance and selector; +2. the exact component identity and workspace-relative source range; +3. the current source hash from the authorized workspace. + +The renderer and preview are untrusted reporters. Main creates and validates the manifest, obtains +current file hashes through existing workspace authority, and applies changes only through Designer +Action review. + +## Source manifest and runtime-instance graph + +`design-source-graph-core.ts` defines the bounded `DesignSourceManifestV1` contract. A manifest is +hash-bound and contains only: + +- stable manifest, workspace, component, and runtime-instance IDs; +- bounded runtime selectors; +- workspace-relative file names, SHA-256 source versions, and exact source ranges; +- custom-component definition identity and runtime parent relationships. + +It deliberately excludes absolute paths, source bytes, commands, preview URLs, credentials, +capabilities, and write authority. Every object rejects unknown fields, paths reject traversal and +backslashes, arrays and serialized bytes are capped, and the manifest hash covers the canonical +body. + +`resolveDesignSourceSelection` fails closed when: + +- a runtime ID and selector do not identify the same single graph node; +- the reported component ID differs from the manifest; +- the request refers to another manifest revision; +- main does not supply a current file hash or that hash changed; +- multiple runtime nodes share one JSX render site; +- a component-definition operation would affect repeated instances. + +This is intentionally stricter than DOM-only selection. A repeated list item may have a unique DOM +selector while every item still originates from one JSX range. The core calls that ambiguous rather +than pretending a source edit affects only one rendered item. + +## Vite HTTP and HMR transport policy + +`source-preview-transport-core.ts` models transport authority as an ephemeral, immutable proof. Main +may issue a proof only for an exact `http://127.0.0.1:` origin that it just observed as +the sole resolved loopback address. `localhost`, hostnames, IPv6 aliases, default ports, URL +credentials, multiple addresses, and non-HTTP origins do not qualify. + +The proof contains explicit HTTP and WebSocket path prefixes, HTTP query-key allowlists, exact +hashed values for internal WebSocket transport parameters, and WebSocket subprotocols. A +structurally identical renderer object is not a proof; only a proof issued inside the main process is +accepted. + +Integration must use manual HTTP redirects and call the policy for the original request and every +redirect destination. It must resolve or otherwise effect-time prove the destination immediately +before each connection. Automatic redirect following is incompatible with this contract. + +HMR has two checks: + +1. authorize the proposed `ws://127.0.0.1:` target, path, query, protocol, and fresh + address observation; +2. authorize the actual upgrade headers, exact `Host`, corresponding HTTP `Origin`, WebSocket + version/key, and protocol list. + +Both HTTP and WebSocket paths reject cookies, authorization, credentials modes, unknown headers, +remote origins, hostname rebinding, port drift, encoded path separators, fragments, and unproven +paths or query keys. `source-preview-websocket-proxy.ts` applies that proof to the real upgrade: it +opens only a numeric IPv4 loopback socket, refuses upgrade redirects, validates the upstream +challenge response, reconstructs a minimal credential-free `101`, and owns every upgraded socket +through teardown. Vite begins with HMR unproven; after the proven `/@vite/client` response exposes +its bounded runtime token, main issues an exact token-hash and `vite-hmr`/`vite-ping` proof. + +## Next.js capability fixtures + +`source-preview-transport-next-adapter.ts` is a pure classifier over normalized, authorized-read +evidence. It does not inspect the filesystem, execute `package.json`, launch a process, or accept +source bytes. Separate fixture axes record: + +- App Router, Pages Router, hybrid, or absent router evidence; +- webpack, Turbopack, ambiguous, or unknown bundler evidence; +- client, server, mixed, or unknown component-boundary evidence; +- current, missing, stale, or ambiguous source-graph evidence. + +The four explicit client/current combinations—App or Pages crossed with webpack or +Turbopack—classify as supported source-selection candidates. `supported` still means HMR requires a +live loopback transport proof and edits require Designer Action review. Server, mixed, unknown, or +non-current source graphs are preview-only. Hybrid/absent routers, ambiguous/unknown bundlers, +non-`next dev` commands, and targets whose host or port is not controlled are unsupported. + +`source-preview-next-runtime-adapter.ts` supplies the authorized-read production side of that +boundary. It reads a bounded real `package.json`, detects `next dev`, chooses the documented Next 16 +Turbopack default or explicit webpack/Turbopack flags, walks non-symlink App and Pages route files, +normalizes static/dynamic route fixtures, and distinguishes App Router server pages from explicit +`use client` pages. It launches through the package manager without a shell override and appends an +exact `--hostname 127.0.0.1 --port ` pair. App and Pages projects use separate route +classifications even inside a hybrid repository; a source edit remains preview-only until a trusted +current source graph is attached. + +## Required integration sequence + +1. Build the source manifest from trusted compiler/plugin output and authorized workspace reads. +2. Pin it to the current preview session and source hashes; never accept a renderer-authored + manifest as authority. +3. Replace automatic preview redirects with manual hop handling through the transport policy. +4.

Push freezes the selected local commit plus named remote and destination; completing one never silently performs the other. | +| Commit ready | `Commit changes` is available when Review has working changes. | Opening it freezes the reviewed snapshot, asks for a message, and makes `Staged changes only` versus `All current changes` explicit. Git hooks and normal signing configuration remain enabled. | +| Commit unavailable | The row remains explanatory for conflicts, detached HEAD, missing Git identity, oversized/unsupported snapshots, and nested workspaces. | Aiden never widens a nested workspace to repository scope. A changed content snapshot is rejected before staging or committing. | +| Commit running / failed | The dialog stays modal while Git runs, pins the originating workspace, and reports the command-specific failure inline. | Aiden locks the real index, builds the reviewed tree in an isolated index, and advances the branch only if its expected ref still matches. Failure leaves the real index unchanged and requires an explicit Review refresh before retry. | +| Commit outcome unknown | The dialog remains in an alert state that says Aiden could not determine whether the branch advanced; it never claims that no commit was created. | The real index stays unchanged. Refresh Review and inspect the branch before retrying so an ambiguous timeout cannot create a duplicate commit. | +| Commit complete | The dialog closes, Review/branch queries refresh, and a concise toast names the subject and branch. | Push is not implied or chained. Post-commit hook or reconciliation trouble is reported as a warning after the successfully created local commit, never as a false failure. | +| Push ready | The dialog names the remote and destination branch, with an optional upstream toggle. | Aiden freezes both the local branch identity and commit hash, then uses an explicit refspec with `--no-force`, no recursive submodule push, no implicit fetch, and normal pre-push hooks/authentication. Ahead/behind labels are explicitly last-fetched local-ref facts. | +| Push unavailable | The action explains no remote, unborn/detached branch, nested workspace, in-progress Git operation, or stale branch state. | Aiden does not widen a nested workspace into a repository-level remote mutation and does not invent a remote or destination. | +| Push running / rejected | The modal and workspace remain locked; non-fast-forward, hook, authentication, and network errors stay inline. | The remote name and destination remain editable after an explicit local-state refresh. Exact-remote reconciliation is reserved for ambiguous timeout or cancellation; an ordinary hook/auth rejection never becomes a false success. | +| Push outcome unknown | The alert directs the user to inspect the remote before retrying. | After timeout/abort Aiden uses `ls-remote` only to reconcile the exact destination ref; that is not a fetch and does not update local tracking refs. | +| Push complete | The dialog closes and a toast names `remote/branch`; upstream-setting trouble is a separate warning. | If Git confirms the exact remote ref after a timeout, the result is success-with-warning rather than a false failure. | +| Compare branch | A dedicated row opens Review in Compare mode. | Targets are exact local branches or last-fetched remote-tracking refs. No selection triggers a network fetch. | ### Review panel states -| State | Visual treatment | Notes | -|---|---|---| -| Not a Git repository | Centered explanatory empty state. | Files remains usable; Review does not imply that Git must be initialized. | -| Clean working tree | Compact success mark with “Working tree is clean.” | This is a meaningful completion state, not an empty-list failure. | -| Changes loading | File-row skeletons followed by diff-line skeletons after selection. | List and selected diff load independently. | -| Changed files | Bounded file list with status glyph, basename, parent path, and `+ / −` counts. | Selection uses the normal Aiden list state; staged and unstaged facts remain available to assistive output. | -| Modified | `M` status and a unified line diff. | A file may be staged, unstaged, or both; the combined view compares the current worktree to `HEAD`.

Rendered HTML elements never become React Flow nodes. +- React Grab owns element hit-testing inside each sandboxed or instrumented document. +- Visual edit mode selects the **exact single DOM `Element` returned by React Grab**. Aiden must not promote a nested text span, icon, button child, or layout container to the nearest `data-aiden-id` ancestor. +- One exact element may be selected per artboard. Shift may preserve selections across different artboards, within the existing bounded context limit. +- An exact element with its own valid `data-aiden-id` uses that stable identity; every other element uses React Grab's exact selector as bounded, untrusted prompt context. +- Selection is context, not authority. It never by itself permits file reads, writes, shell execution, network access, source changes, Git operations, or tool escalation. +- The selected provider and model remain unchanged. Design uses the current Aiden AI backend rather than a second agent stack. +- Generated-design edits return complete immutable HTML revisions. Source-backed edits use a main-owned, hash-bound proposal and approval transaction. +- GitHub import, plugin install, pull requests, deploy, sharing, multiplayer, and hosted collaboration are not MVP requirements. + +## Shipped foundation + +### Phase 1 — focused generated-design backend — complete + +- `design: true` is an exact, main-validated attended-turn intent and cannot combine with `/visualize`. +- A positive capability allowlist leaves only the Design-owned `render_artifact` extension; coding, file, shell, web, MCP, schedules, skills, Computer Use, image generation, Telegram controls, and subagents remain unavailable. +- `render_artifact` accepts complete inline vanilla HTML/CSS/JS documents. Cross-turn results are immutable `design:` artifacts in app-owned, crash-recoverable storage. +- Main revalidates exact media IDs and content hashes, loads only app-owned HTML, caps combined context at 128 KiB, and marks prior designs and element descriptors as untrusted model reference data. +- The existing opaque-origin `sandbox="allow-scripts"` iframe, network-denying CSP, strict validator, storage quotas, export flow, and native transcript contract remain authoritative. +- The Design brief supports up to four requested screens, stable titles for revisions, distinct titles for new artboards, responsive semantics, keyboard states, and meaningful `data-aiden-id` markers. + +### Phase 2 — first-class full canvas — complete + +- `Design` appears beside Scheduled and Bots in the persistent sidebar. +- `/design` resolves an eligible ordinary chat in the active workspace and `/design/$chatId` owns the stable studio URL. +- The route replaces the conversation body with a full-height canvas while keeping the persistent app sidebar and the durable chat/provider/model owner. +- The prompt composer floats above the continuous canvas instead of sitting in a footer surface. +- Design cards deep-link to their route and revision. The Design route does not mount Environment, Terminal, a side workbench, or a compact modal. +- Empty, generating, ready, stale-preview, unavailable, desktop, tablet, phone, revision, and export states remain truthful. + +### Phase 3 — spatial HTML/CSS studio — complete + +- React Flow provides the infinite canvas, multiple grouped-revision artboards, local image-reference nodes, pan/zoom/fit, artboard selection, and placement. +- The left rail provides Select (`V`), Visual edits (`E`), Preview, New design, Upload image, and Hand (`H`); Space-drag remains available. +- Image references are local, bounded vision attachments and may be combined with selected artboards for the next prompt. +- A pinned, vendored React Grab primitives bundle runs only inside Design guests. It keeps telemetry and network access absent and is excluded from exports and ordinary artifact previews. +- The guest bridge validates the parent command and per-preview capability. The host validates the exact iframe window, capability, schema, string bounds, media ID, artifact hash, and chat ownership. +- React Grab returns exact element context: tag, label, selector, optional own `data-aiden-id`, role, and safe short text. Form values, URLs, raw source, filesystem paths, IPC, and unrestricted HTML are excluded. +- Element, artboard, and image selections appear as removable chips in the elevated composer and apply to one accepted turn. +- Same-title output creates another revision of an artboard; distinct stable titles create new artboards without losing canvas state. + +## Shipped source-backed MVP + +The following phases extend the same Design Workspace. They do not silently attach repository power to generated artboards. + +### Phase 4 — containment, lifecycle, and identity proof — complete + +- A real Vite/React fixture proves the chosen sandboxed-iframe architecture; Electron `` and remote browsing remain disabled. +- A person must explicitly start one detected root-package Vite script. Main launches direct argv with `shell: false`, assigns a loopback port, bounds logs and readiness time, scopes ownership to workspace and renderer document, and tears down the process group. +- A main-owned read-only reverse proxy strips unsafe response headers, injects the pinned React Grab bridge, and accepts only GET/HEAD requests to the owned loopback target. +- React Grab source context is treated as untrusted evidence. Main canonicalizes the workspace, resolves only supported source files, rejects ambiguous suffix matches, and verifies the exact intrinsic JSX tag before creating a binding. +- A stable `id`, `data-testid`, or `data-aiden-id` may recover an exact intrinsic JSX element only when that same tag/attribute/value match is unique in the uniquely resolved file. Otherwise selection is unsupported. +- Browser coverage proves exact nested-element binding, unchanged source before approval, one exact write, exact undo, and fail-closed handling for an unmapped child. + +### Phase 5 — source-backed read-only preview — complete + +- **Connect app** lives inside the existing full Design route and shows the exact detected command before Start. +- The running source app appears as a React Flow artboard and can coexist with generated artboards and image references. +- Preview lifecycle, script detection, capability, logs, loopback endpoint, and stop behavior are main-owned and exposed through bounded workspace/owner-scoped IPC. +- Unsupported roots, launch failures, timeouts, crashes, and stopped states remain explicit. The MVP supports root-package scripts whose command directly invokes Vite. + +### Phase 6 — exact source-backed element selection — complete + +- Visual edit mode uses React Grab for the exact single DOM element. The renderer receives a bounded descriptor; only main may turn it into a workspace path and JSX range. +- Main binds the selection to renderer owner, workspace, preview session, canonical file, exact range, source hash, and a two-hour opaque selection handle. +- Ambiguous files, unsupported extensions, custom-component-only positions, mismatched tags, missing source metadata, repeated stable selectors, and changed source fail closed. +- The source selection appears in the shared composer-chip language and excludes generated artboard/image context for the same turn. + +### Phase 7 — Designer Action foundation — complete + +- Source-backed Design generation gets one structured `propose_design_action` capability rather than general mutation tools. +- Each proposal is bound to workspace, chat, opaque selection, exact canonical file/range, source preimage hash, bounded replacement, and a plain-language label. +- Every proposal opens a mandatory floating Designer Action review with before/after source. Full workspace permission never bypasses this review. +- Apply rechecks ownership and preimage, uses the versioned workspace writer, and records the postimage hash. Undo proceeds only while that exact postimage remains on disk; external edits become an explicit stale action. +- Deny writes nothing. No Designer Action runs Git staging, commits, stash, checkout, reset, whole-tree restore, or a shell command. + +### Phase 8 — point → ask → review → apply → undo — complete + +- Selecting a proven source element adds an exact source/path chip to the elevated composer and sends only an opaque main-resolved selection handle to generation. +- The model proposes a replacement; it cannot apply it. The user reviews and chooses Apply or Deny in the canvas. +- Apply or Undo advances the source artboard revision and reloads the preview. The review remains available for exact undo after apply. +- Unit, IPC-contract, renderer-contract, vendor, and real Chromium/Vite coverage exercise the shipped flow and its failure boundaries. + +This completes the first source-backed MVP. The implementation deliberately ships a narrow, auditable path rather than claiming universal DOM-to-source editing. + +## MVP limitations carried forward + +- Root `package.json` only; no monorepo package picker, nested app discovery, route chooser, or arbitrary command entry. +- Vite/React only; no Next.js, webpack, Turbopack, Vue, Svelte, or remote URL adapter. +- One proven intrinsic JSX range and one file per Designer Action. Custom-component definitions, repeated instances, fragments, portals, shadow roots, and multi-file edits fail closed or remain preview-only. +- React Grab/sourcemap evidence plus exact tag or unique stable selector replaces a repository source transform in this slice. There is no source manifest or runtime-instance graph yet. +- Action history is scoped to the running app session. It is not a durable cross-restart ledger. +- The proxy is intentionally read-only and does not proxy Vite WebSocket HMR. Aiden forces an iframe revision reload after Apply/Undo; the dev server may still perform its own client-side HMR. +- Static Tailwind/global-CSS context, layers, property editing, direct manipulation, component insertion, and generated-to-repository handoff remain later depth. + +## Later depth + +1. Root/package/route selection for monorepos and multiple Vite apps. +2. A durable action ledger and versioned multi-file transaction with crash recovery and conflict review. +3.

Existing iOS generic-hardware test compilation and Android unit/test compilation evidence is recorded above. +- Developer ID signed development package passed hardened-package verification and isolated launch/restart acceptance: V2 creation, reviewed Design Language save/apply, persistence after restart, detach, and empty-export rejection. An Apple timestamp-service failure during rebuilding was retried without changing signing requirements. +- Final combined reviews were clear after reconciling export state across Refine, Detach, and Connect App. Completed handoff replay remains idempotent after later source changes. +- This completes source implementation and local automated acceptance.

Reject unsafe YAML features, raw HTML, embedded resources, executable directives, paths, credentials, unsupported encodings, control characters, and oversized/deep input. +- Treat all imported human guidance as inert untrusted model context. + +Acceptance: prototype-only projects work without Connect App; canonical import/export round trips preserve the normalized hash; malicious fixtures and stale workspace snapshots fail closed. + +## Phase 5 — Prototype graph + +- Store exact Screen/revision nodes and whitelisted interaction edges separately from HTML. +- Allow bounded click, submit, change, and keyboard triggers with validated destinations and transitions. +- Keep static, unverified, verified, broken/stale, and connected-preview states distinct. +- Verify through the existing network-denied preview host, recording exact source hashes and bounded check evidence. +- Make missing states, keyboard/focus, reduced motion, and link validity explicit checks rather than unverified claims. + +Acceptance: no legacy or generated Screen is labeled interactive without verification; stale/remapped revisions visibly invalidate affected edges; the bridge cannot navigate outside its exact project/iframe capability. + +## Phase 6 — Export and handoff V2 + +- Preserve existing single-Screen export. +- Add a versioned deterministic project bundle containing a Project Brief, `DESIGN.md`, exact Screen sources, prototype graph, and bounded references. +- Extend the existing recoverable handoff journal with chosen direction, reviewed Screen subset, Design Language hash, prototype summary, responsive intent, accessibility notes, and exact source hashes. +- Integrate every new project-owned record into duplicate, delete, recovery, and health-check lifecycles. +- Keep export, Connect App, and Continue in Workspace as distinct authority boundaries. + +Acceptance: identical reviewed scope produces byte-identical output; stale preview digests require re-preview; no prompt, transcript, credential, absolute path, implicit permission, or rejected source crosses the boundary without explicit review; all V1 journals remain recoverable. + +## Cross-cutting verification + +- Exact-key parsing, bounds, Unicode, future-version, migration, rollback, and corruption fixtures. +- Store CAS, two-window conflict, crash-boundary, restart reconciliation, duplicate, delete, and feature-disable tests. +- Electron E2E for new project, Show on canvas, History preview, Code rail, offscreen recovery, Explore/cancel, exact-base Refine, Design Language, Prototype, export, relaunch, and preview cleanup. +- Accessibility coverage for roles, names, focus-visible, text-entry focus rules, keyboard-only operation, VoiceOver, reduced motion, high contrast, and forced colors. +- A 20-Screen/10-reference/100-revision fixture with a hard live-iframe cap and truthful offscreen placeholders. +- Full Generative UI, Design recovery, remote exclusion, type-check, lint, build, and exact-head CI gates.

A project-injected browser script and the editor communicate through Penpal. Both inspected Penpal endpoints allow `*` origins. | Reuse the interaction idea, not the bridge security model. | -| Source identity | `CodeFileSystem` mutates JSX/TSX source on write, adding random `data-oid` attributes, then builds `.onlook/index.json`. The indexer only maps AST nodes that already contain an OID. | A source-clean build transform and a separately run Onlook indexer cannot work together. Aiden needs one shared transform/manifest contract. | -| Runtime identity | Onlook distinguishes source OID, runtime DOM ID (`data-odid`), and component-instance ID (`data-oiid`). | Definition versus runtime instance is an MVP identity concern, not late toolbar polish. | -| Selection | A transparent gesture layer hit-tests the iframe, including open shadow roots, then renders editor-side overlays. | The coordinate system and invalidation contract must cover host bounds, scroll, scale, HMR, resize, and device scale. | -| Writes | Direct style actions are recorded in an in-memory history/transaction layer, written to source, and then reflected in the iframe. | The earlier “instant CSS first, async persistence second” description was inaccurate. Aiden should design its own proposal-first order. | -| AI context | Selected elements become highlight context and their content is refreshed. Normal design chats do not automatically attach the style guide on every turn; the style guide is attached during create/resume or read through a tool. | Main must re-resolve the full selection and source version before send. Automatic bounded style context would be an Aiden improvement. | -| Undo | Toolbar actions have in-memory undo/redo. AI completion also creates broad Git checkpoints with `git add .` and `git commit --allow-empty --no-verify`; restore uses a safety commit and `git restore --source … .`. | Do not copy the Git algorithm into a user's real checkout. | -| Local provider | `NodeFsProvider`, its watcher, terminal, tasks, and commands are placeholders. Live editor sessions use CodeSandbox. | Aiden should use its existing local services; there is no local Onlook provider to port. | -| License | The repository is Apache-2.0 and has no `NOTICE` file in this checkout. | Copied/adapted code needs a provenance ledger, the license, preserved notices, and modified-file marking where required. | - -Useful ideas to reimplement: deep element hit-testing, coordinate math, selection-context shape, parser fixture pairs, runtime DOM IDs, action grouping, and static token extraction. - -Do not copy wholesale: Penpal bridge code, MobX/editor-engine React surfaces, the internal UI color picker, the roughly 3,500-line `// @ts-nocheck` Tailwind translator, or the source-wide Babel/Prettier write path. - -### Aiden - -- The main renderer is context-isolated, sandboxed, and has Node integration disabled. Guest content is not currently enabled. -- The current Environment surface is a 480–720px Review/Files work surface. At the default 1000px window width it becomes an inert overlay, so merely adding a Preview tab would break the point-then-type loop. -- Terminal sessions are interactive shells. They do not own a dev command, readiness URL, logs, or server lifecycle. -- Ask approval is per mutating Pi tool call and applies only in Ask mode. Full mode bypasses it. The current tools cannot batch N files or enforce a selected source region. -- Review shows the whole working tree against `HEAD`; it has no action baseline or action-specific summary. -- Git and Files already have strong workspace-ID authorization, stale-snapshot checks, safe path resolution, temporary-index commits, and atomic version-checked saves.

Preview containment: prefer an instrumented sandboxed iframe - -The first candidate is a sandboxed iframe plus a browser-only bridge injected by the Aiden Vite adapter. This keeps project code out of Electron's privileged preload world and follows the shape already proven by Onlook. - -Do not enable Electron `` for the MVP. It is disabled in Aiden today, and Electron [currently recommends alternatives](https://www.electronjs.org/docs/latest/api/webview-tag) because of webview stability and event-routing concerns. Phase 0 must still compare the iframe with a main-owned `WebContentsView` if frame headers or compositor behavior make the iframe unworkable. Any alternative must satisfy Electron's [security checklist](https://www.electronjs.org/docs/latest/tutorial/security). - -The iframe contract: - -- Canonical loopback `http:`/`https:` origins only; reject credentials, non-loopback hosts, unsafe schemes, redirects away from the approved origin, and the Aiden renderer origin. -- No popups, downloads, top navigation, camera, microphone, geolocation, clipboard, or filesystem privileges. -- Add the narrow `frame-src` needed by Aiden's CSP; do not widen `script-src` for preview code. -- Use a per-preview random capability in a typed `postMessage` handshake. Validate `event.source`, origin, capability, method, payload size, and schema on every message. -- Treat every guest field as untrusted. The guest may return opaque source/runtime IDs and geometry only; main resolves IDs to workspace files. -- The guest bridge exposes DOM inspection and temporary visual-preview operations only. It never receives `window.aidenAPI`, arbitrary IPC, Node, paths, file contents, or command execution. - -If an iframe requires changing `X-Frame-Options` or `frame-ancestors`, only the Aiden-owned local adapter may adjust the dev response. Never weaken a remote response. - -### 2. One adapter owns instrumentation and the source manifest - -The Vite adapter must emit both sides of identity from the same transform: - -- `SourceElementId`: opaque ID injected into rendered JSX during development only. -- `DomInstanceId`: unique runtime ID assigned to each actual DOM node so repeated `.map()` output can be hit-tested independently. -- `SourceManifestEntry`: workspace-relative path, component, tag, AST locator, start/end offsets and lines, dynamic/shared flags, source hash, and adapter version. -- `ManifestRevision`: changes atomically whenever transformed source changes. - -The adapter and main process may share a deterministic ID/manifest library, or the adapter may publish the manifest through an authenticated loopback side channel. They may not run independent random transforms. - -No derived index or code block belongs in the user's repository. Keep it in memory and under Electron `userData`, keyed by workspace identity, canonical root, adapter version, and source revision. Never persist absolute paths or code in renderer storage. - -The activation mechanism must be proven: Aiden should start the workspace's local Vite binary with a temporary wrapper/config outside the repository, preserving the user's config without editing it. If this cannot be made reliable, the Phase 0 decision is either: - -1. allow reversible source instrumentation only inside an explicit disposable managed worktree, with crash-safe strip/recovery; or -2. stop at read-only Preview. - -Never inject marker attributes into an arbitrary dirty checkout as an automatic fallback. - -### 3.
