mathiasandClaude Opus 5.5	b6f7dac46e	fix(brain): context, brain_get and brain_read read through brainfs (#157, slice 2) ... Option 1 of #157, slice 2. readExcerpt (brain_context), api.ReadNote (brain_get / read-after-write) and notes.ReadScoped (brain_read) read the Syncthing-shared brain by path. Under a symlink swap race each leaked an outside file hundreds of thousands of times in 1.5s, including brain_read, whose Lstat check was raced by the reopen-by-name; a FIFO blocked os.ReadFile. - All three read through brainfs (os.Root, regular files only, non-blocking open, type check on the handle). - brainfs.ReadRegularMax checks a size limit on the opened handle; notes keeps its ErrTooLarge. - New internal/brainfs/brainfstest: the shared swap-race harness (symlink and held-writer FIFO swappers, awaited before TempDir cleanup; AssertNoLeak / AssertNoHang) for this and later slices. Tests red first: each reader under a symlink-swap race and a held-writer FIFO race, plus static checks. Flipped: readExcerpt back to os.ReadFile is red.

mathiasandClaude Opus 5	125c99bb46	fix(text): truncate on rune boundaries, not byte offsets (#93) ... Four call sites did `s[:limit] + "…"`. Both halves are byte operations: len() counts bytes and a slice cuts bytes. On Swedish text — å ä ö are two bytes, an em dash three — the cut lands mid-character and leaves an orphaned lead byte, producing invalid UTF-8. It failed loudly in exactly one place: wiki/index.md is written raw to disk, where every strict decoder then rejects the whole file. The other three (brain_context excerpts x2, brain_query excerpts) feed MCP responses, where encoding/json silently substitutes U+FFFD — so those had been quietly eating the last character of truncated excerpts, with no error anywhere and nothing to notice. textutil.Truncate counts runes and appends the marker only when content was actually dropped; an ellipsis on complete text is a lie about the content. The test is a property, not an example: it walks the limit across every offset of a multi-byte string and asserts utf8.Valid at each one, so a future off-by-one cannot pass by picking a lucky boundary.

mathiasandClaude Opus 5	3e537bd582	feat(brain): surface an aging review queue in brain_context (#82) ... brain_pending existed the whole time four real items sat unreviewed from 2026-04-23 to 2026-07-15. The tool was never the gap — nothing ever prompted anyone to call it. The system should be what remembers the queue exists. Option 2 from the issue: ride along with brain_context, which sessions already call, so noticing an aging note costs nobody a decision to go looking. No scheduled job, no ntfy wiring, nothing new to keep running. Threshold-gated at 14 days, and silent below it — a notice on every context call is one people learn to skip, which reproduces the original failure with extra steps. It reports the whole queue once it speaks: the threshold decides whether to talk, not what to count. It never promotes, rejects or reorders. Age is a reason to ask a human, not a verdict; an old note may be exactly right to promote once someone looks. A test asserts the queue is untouched and that the payload carries a hint rather than an action. An unreadable raw/ dir degrades to silence — brain_context is a hot path and must not fail because the review queue is broken.

mathiasandClaude Opus 4.7	2726896079	feat(mcp): wire brain_context tool ... Returns top-N relevant brain entries for a project context. Combines BM25 hits on project name with 2-hop graph expansion via Track A's graphstore (when BRAIN_GRAPH_ENABLED). Closes hyperguild#28. Notes on implementation choices that deviate slightly from the spec: - Excerpt length: 200 chars per spec (vs the 300 used by search.Result). truncateExcerpt clamps the already-stripped BM25 excerpt; graph-only neighbours load their excerpt from disk via a private readExcerpt helper (search.hydrate is unexported). - Graph scoring: 0.6 / max(1, distance) per neighbour, so distance-1 contributes 0.6 and distance-2 contributes 0.3. BM25 hits decay linearly from 3.0 (rank-0) to 1.0 (rank-2), giving BM25 hits a natural ceiling above pure-graph hits while still letting a doc surfaced via both edge types outrank a BM25-only one. - Test placement: package mcp (internal) rather than mcp_test, because graphReader is unexported and WithGraph only accepts *PGStore; an internal test can install a dual-interface fake directly on s.graph without spinning up postgres.
