mathiasandClaude Opus 5.5	a6da93332d	feat(brain): audit-log every tools/call; server-owned write provenance (#147) ... Closes #144 (audit line per tools/call) and #145 (origin/written_by stamped on every model-reachable write, surfaced in brain_query/brain_get). Passed pr-gatekeeper after four rounds of adversarial review, verified by execution: #147 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Mathias <mthbqv@gmail.com>	2026-10-01 21:06:36 +00:00
mathiasandClaude Sonnet 5	e157311cd8	fix(mcp): validate the claim envelope before brain_edit writes too (#136) ... 7 review rounds closed 8 distinct bypasses across two mechanism families: fence-detection (field-name substring, block-containment, fence-stripping, CRLF, UTF-8 BOM) and value-extraction (folded YAML block scalar hiding an invalid value). A known v1 gap remains in the block-scalar fold's handling of blank-line-interrupted continuations — documented on checkClaimEnvelope, accepted deliberately (narrow, requires an already-privileged caller deliberately constructing a specific malformed-YAML shape) rather than chased past diminishing returns. Real fix (shared, tested, encoding-normalized frontmatter parser) tracked separately as hyperguild#138.

mathias	5a5d938e8e	Brain-quality sweep, batch 1: brain_edit/brain_update correctness + close-session docs (#124) ... Co-authored-by: Mathias <mthbqv@gmail.com>	2026-09-22 21:27:11 +00:00
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.
