From f318eb05a46ebdd410774fbc42a2f0a8bc8cc92c Mon Sep 17 00:00:00 2001 From: Petrus Pennanen Date: Thu, 1 Oct 2026 02:27:43 +0200 Subject: [PATCH 1/6] feat: room archive and search, a local memory of a room's whole history petrus, 1 Oct 2026: "can you index the room so you have a memory here? add it to IAK". - src/room-archive.mjs: one append-only JSONL per room (~/.ide-agent-kit/room-archive, or room_archive.dir), deduped by id on load, tolerant of a torn last line. Sync pages backwards with an URL-encoded before= (newest-first pages of 100), stops on overlap with the archive, and refuses to loop when the server ignores before=. Search: all words or a regex, from / since / until filters, newest first, and a scope report (0 hits = not in the archive). - MCP tools room_search and room_archive_sync; CLI `rooms search` and `rooms archive`. - Safety (codexmb review notes): only rooms in this config are archived, never DMs; output is labelled untrusted evidence; credential-looking values are redacted in tool output and the kinds are reported, while the archive itself stays verbatim; nothing lands in the repo. Measured: 40,000 messages of thinkoff-development archived back to 2026-02-27 in 590 s; an incremental sync takes one page. Tests: 9 new, 823/823 total pass.

each has a test that fails on that head: - A sync whose page budget ran out before reaching the archive left m100..m199 missing forever. It now records where it stopped (.state.json) and the next sync walks on until it meets the older block; gapPending reports an open hole. - A crash fragment without a newline swallowed the next appended record; a newline now closes the fragment before appending. - room_search redacted only the body; every string field of a hit is redacted now. - New files were 0644 under the default umask; directory 0700 and files 0600, and existing archives are tightened on load. - A sync that the server refused (401/403/404) used to fall back to cached hits; it now returns no archived text. sync:false still checks access with a one-message request. A network failure still returns the archive, labelled stale. - README and the tool note now say the archive is a snapshot (later edits and deletions are not reconciled).

Gap state is now written per page, in the order that survives a crash at any point: - opening a gap records it BEFORE the page is appended (the hole lies below that page); - healing appends the page BEFORE the cursor moves (a crash re-fetches the page, appends are idempotent by id; moving first would skip the page for good). Tests: his failure-after-page-1 reproduction (fails on c4f2669), and a crash mid-heal, which fails on the cursor-first ordering.

Reworking the order exposed a deeper flaw: healing stopped when a page held an id already in the archive. A crash after a page was saved but before its cursor moved made the next run re-fetch that page, see known ids, and close the gap with the hole below still open. - A gap is now { before, until }: `until` is the newest message of the archived block below the hole, fixed when the gap opens, and healing stops by time, so re-fetching a saved page can never close a gap early. Bare-cursor state files from earlier commits are migrated. - A gap is opened before its first page is saved and advanced only after each further page is on disk; healing saves the page before moving the cursor. - New exhaustive test: a crash injected at every add() and every saveState() call of a gap-producing workload (28 crash points), restart, and require all 900 messages. It fails on 4554d22 at add #2; the two targeted reproductions are kept too.

With gaps pending, one page per call is now kept for healing (budget >= 2), or newest and healing calls alternate (budget 1). Test: reload, then maxPages 1 calls heal m100..m199 and still pick up a new message at the newest end; it fails on fa4dfa4. The module header now says exactly what the crash tests prove: an exception at every page save and state save recovers fully; that is not a power-loss/fsync guarantee (writes are not fsynced). It also restates the snapshot, offline-stale and refusal policies and that gaps from older state files keep the id-based stop.
