mathiasandClaude Opus 5.5	f4636c7ef0	fix: creating and generated writes go through the brain root (#188, #158 part A) (#189) ... New brainfs PutRegular (create or replace), CreateRegular (create only), AppendRegular, Remove and RealParent: missing parents created one component at a time through the root, every existing component a real directory, new files created with O_EXCL and confirmed before writing. brain_write, promote/reject (O_EXCL create, source kept on refusal), StampProvenanceFile, BuildWingIndex, RebuildIndex, AppendLog and the tunnel candidate log use them; provenance.ApplyFile removed. Fixes #188. Refs #158. Adversarial review: BLOCKED, BLOCKED, PASS. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Mathias <mthbqv@gmail.com>	2026-10-05 21:25:54 +00:00
mathias	0c3e82ca0a	test(brainfs): per-caller in-brain symlink targets for slices 1-3 (#171) (#172) ... Co-authored-by: Mathias <mthbqv@gmail.com>	2026-10-05 19:36:31 +00:00
mathiasandClaude Opus 5.5	27a01dd2af	fix(brain): context, brain_get and brain_read read through brainfs (#157, slice 2) (#165) ... readExcerpt, ReadNote and ReadScoped now read through brainfs (os.Root, regular files only, type checked on the opened handle), so a symlink swapped in after a check is not followed and a FIFO does not hang the reader. ReadRegularMax bounds the read itself with io.LimitReader(max+1). notes.Target carries the brain root. Refs #157. Adversarial review round 2: PASS (round 1 BLOCKED: unbounded read, rule-9 test names).

mathias	36a45068ab	feat(mcp): record and alert on a governance-file rewrite (#97) (#98) ... brain_edit_root was gated but unobserved: on success it emitted a slog.Warn and nothing else. That proves a rewrite was allowed, not that one happened — and brain-sync commits it within 15 minutes authored `brain-sync`, so git history cannot tell a CLAUDE.md rewrite apart from routine note traffic. A successful brain_edit_root now emits an ntfy notification and an AuditEntry through the same sink a capture already uses. notes.Result gains PrevContentHash so both ends of the change are identifiable. Path and hashes only in the notification body. Reserved at Internal, not Confidential, because Confidential makes DegradingSink refuse to record while loki is down rather than buffer. Observation is best-effort and never fails the call; a failure to observe logs at ERROR. Ordinary brain_edit on knowledge//wiki/ is deliberately not audited — git history already carries the same before/after bytes with a diff. Closes #97.

mathias	055af368cd	feat(mcp): brain_read + brain_edit, contained to the sync source (brain#4) (#96) ... brain_read returns a note verbatim; brain_edit is str_replace with an exactly-once match, operating on the tree brain-sync commits from. An adversarial design review before implementation changed three things: 1. Governance files are not in the model-facing tool. Brain content is ingested from the outside world and reaches a model's context, and that model would hold the editor — one poisoned page could rewrite the CLAUDE.md a .dispatch-allow agent later loads as instructions. And brain-sync merges with --strategy-option=ours, so the live tree beats a human's corrective push on the conflicting lines. CLAUDE.md now goes through brain_edit_root: de-surfaced from tools/list and gated on the local static principal. The scopes are disjoint — the privileged door has the smaller reach. 2. Reads needed the same allowlist, and brain_get already lacked it: it returned verbatim session transcripts under archive/ by path. A test proved the exposure live before the fix. 3. Canonicalise before allowlisting — knowledge/../.git/hooks/post-commit would otherwise reach a hook that brain-sync executes in a pod holding the Gitea push credentials. Plus overlapping match counting, UTF-8 validation both ways, refusal while git is mid-operation, flock with the read inside the lock, atomic same-dir rename, and reindex only when frontmatter is touched.
