cd8efee0ea v0.41.15.0 feat(sync): --timeout + --max-age + partial status (closes #1472 RFC) (#1506)
* feat(sync): migration v98 last_refreshed_at + deleteLockRowIfStale helper

Schema foundation for v0.41.15.0's `gbrain sync --break-lock --max-age <s>`
flag. Adds `gbrain_cycle_locks.last_refreshed_at TIMESTAMPTZ` as the
heartbeat signal that distinguishes wedged-but-alive lock holders from
healthy long-running syncs that are actively refreshing.

Why last_refreshed_at not acquired_at: `withRefreshingLock` already bumps
`ttl_expires_at` every ~5 min while work runs, but leaves `acquired_at` at
the original timestamp. A 35-min media-corpus sync that's healthy has
`acquired_at` 35 min ago but `last_refreshed_at` 30 seconds ago. Using
acquired_at for --max-age would steal healthy locks; last_refreshed_at
correctly identifies only holders whose JS interval has stopped firing.

D-V4-1 rollout safety: migration v98 backfills `last_refreshed_at = NOW()`
(NOT `= acquired_at`) so pre-upgrade holders running the old binary get a
30-min protection window. After that window all pre-upgrade syncs are
either complete (lock released) OR genuinely wedged (--max-age does the
right thing). Documented as a known caveat in CHANGELOG.

D-V4-mech-4 SQL cast: deleteLockRowIfStale uses `$N * INTERVAL '1 second'`
not `$N::interval` (Postgres does not cast integer to interval the latter
way). Atomic DELETE keyed on (id, holder_pid, last_refreshed_at < NOW() -
$N * INTERVAL '1 second') RETURNING id, last_refreshed_at — no TOCTOU
between inspect + delete.

D-V4-mech-3 schema-snapshot parity: column added to all 3 snapshots so
fresh init paths (pglite-schema.ts, schema.sql) initialize correctly
without depending on the migration runner. schema-embedded.ts regenerated
via `bun run build:schema`.

Pinned by 13 PGLite cases in test/sync-break-lock-all.test.ts:
tryAcquireDbLock writes on INSERT, withRefreshingLock refresh bumps both
columns, inspectLock surfaces the new field, deleteLockRowIfStale refuses
fresh / breaks stale / safe on holder_pid mismatch / refuses NULL
(pre-v98). R1 + R6 regression invariants from the v4 plan.

Closes #1472 (RFC from @garrytan-agents) — schema foundation only;
performSync abort threading + CLI flags + consumer threading land in
follow-up commits in this PR.

* feat(sync): --timeout + --max-age + partial status + per-source AbortController

The CLI surface for v0.41.15.0. Wires `gbrain sync --timeout <s>` (graceful
self-termination) and `gbrain sync --break-lock --all --max-age <s>`
(cron-self-heal) end-to-end through `performSync`, `runOne`, `runBreakLock`,
and all `SyncResult.status` consumers.

Surface 1: `gbrain sync --timeout <s>`
  - New `SyncOpts.signal?: AbortSignal` threads through `performSync` →
    `withRefreshingLock` work callback → `performSyncInner`.
  - D-V3-1 honest scope: abort checks fire ONLY in pre-bookmark phases
    (pull, delete, rename, import). Extract + embed run to completion if
    reached. The `last_commit` bookmark write at sync.ts:1261 is the
    invariant boundary — partial CANNOT advance the bookmark because the
    abort checkpoints sit strictly before that write.
  - D-V3-2 per-iteration: abort check at top of every loop iteration
    (delete, rename, serial import, each parallel worker's while loop)
    matches the per-file granularity the existing loops already have.
  - D-V3-3 per-source AbortController: `--timeout --all` creates ONE
    controller inside runOne per source so each gets its own budget;
    NOT a shared global controller (which would starve later sources).
    try/finally + timer.unref() guarantees cleanup on throw.
  - D-V4-mech-7 pull error.cause: pullRepo wraps execFileSync errors in
    GitOperationError. The catch inspects e.cause.code === 'ETIMEDOUT'
    and e.cause.signal === 'SIGTERM' (NOT the top-level error) to
    distinguish timeout (partial reason='pull_timeout') from ordinary
    pull failure (existing warn-and-continue, R2 invariant preserved).

Surface 2: `gbrain sync --break-lock [--all] [--max-age <s>]`
  - Drops the --all refusal at sync.ts:1610. When combined with --all,
    runBreakLock iterates every active source and prints per-source verdict.
  - --max-age routes through the new deleteLockRowIfStale helper from
    db-lock.ts (atomic age-gated DELETE; no TOCTOU). Healthy refreshing
    holders survive by construction; only wedged-but-alive holders trip.

D-V3-5 partial-status consumer threading (conservative posture matching
blocked_by_failures):
  - printSyncResult: new `case 'partial':` arm reports filesImported +
    reason; tells operator to re-run to continue.
  - manageGitignore (both single-source and parallel runOne sites,
    plus watch mode): excludes partial from the gate. A partial sync's
    db_only path set isn't fully reconciled.
  - Auto-embed-backfill enqueue inside runOne: excludes partial. The
    next clean sync will re-walk and re-decide.

CLI flag parsing (T16):
  - parseDurationSeconds in sync-concurrency.ts: accepts 60s/10m/1h/bare
    int; rejects 0/negatives/decimals/garbage. Names the failing flag in
    the error message.
  - --timeout requires --source OR --all (validation rejects bare
    `gbrain sync --timeout`).
  - --max-age requires --break-lock; mutually exclusive with
    --force-break-lock.

Coverage:
  - 15 unit cases (test/sync-timeout.test.ts) pin parseDurationSeconds +
    SyncResult union additivity.
  - 2 E2E cases (test/e2e/sync-parallel.test.ts) pin the abort-mid-import
    contract against real Postgres: status='partial', last_commit
    unchanged, filesImported bounded.

Closes #1472 (RFC from @garrytan-agents) — CLI surface; schema foundation
landed in the previous commit.

* test(heavy): sync_timeout_rescue.sh reproducer for the cron-cascade

10K-page seed × 4 sources × deliberately tight --timeout × 3 sequential
cron emulations. Asserts every source reaches `last_commit === HEAD`
within 3 waves. Proves the v0.41.15.0 fix breaks the cascade the
PR #1472 RFC documented.

Workload (tests/heavy/_sync_timeout_rescue_workload.ts) is PGLite-only
because the PGLite engine forces serial sync internally (parallelEligible
excludes it). The parallel-fan-out + per-source AbortController case
lives in test/e2e/sync-parallel.test.ts against real Postgres. This
heavy test pins the contract that matters for cron: aborts → partial
returns → next wave content_hash-short-circuits + makes new progress.

Smoke-tested locally at PAGES=50 WAVES=2 TIMEOUT_SECONDS=2: every
source converges within 2 waves.

* docs(v0.41.15.0): CHANGELOG + README + TODOS + version bump

Bumps VERSION + package.json to 0.41.15.0 (next slot after master's
v0.41.14.0). CHANGELOG entry leads ELI10 per gstack voice rules and
documents the 3 intentional honest gaps:
  1. --timeout covers pull + delete + rename + import only; extract +
     embed run to completion (D-V3-1 honest scope).
  2. First 30 min after migration v98, --max-age cannot identify wedged
     pre-upgrade holders (D-V4-1 rollout trade-off).
  3. Full-sync triggers (first sync, --full, chunker-version rewalk)
     don't respect --timeout yet (deferred to v0.42+).

README troubleshooting section: paste-ready cron pattern with shell
timeout(1) for OS-level process isolation + gbrain's --timeout for
graceful self-termination half-a-minute earlier.

TODOS.md: v0.42+ entries for subprocess fan-out (revisit if shell
timeout(1) proves insufficient), full-sync --timeout coverage via
AbortSignal in runImport, and runFactsBackstop microtask-queue
process-alive caveat.

llms-full.txt regenerated via `bun run build:llms`.

Closes #1472 (RFC from @garrytan-agents). Credit to @garrytan-agents
in the CHANGELOG for surfacing the production cron-failure data that
motivated the work.

* fix(test-isolation): rewrite JSDoc to not match mock.module() lint regex

scripts/check-test-isolation.sh greps for the literal string `mock.module(`
to flag top-level module mocks (R2 rule — top-level mocks leak across files
in the shard process). The regex doesn't know about comments, so my two new
test files tripped the lint with JSDoc lines literally describing the rule:

  test/sync-timeout.test.ts:11   "* `mock.module()` (R2). Engine ..."
  test/sync-break-lock-all.test.ts:15  "* mock.module(), no process.env ..."

Both files had ZERO actual mock.module() calls — only the comment text
matched. Rewrote both JSDocs to refer to "top-level module mocks" instead
of the literal token. Same meaning; doesn't trip the regex.

`bun run check:test-isolation` now passes (714 non-serial unit files
scanned). `bun run verify` clean (22/22 checks pass).

3de06b6c29 v0.38.2.0 fix(doctor): bounded frontmatter scan + partial-state surfacing (supersedes #1287) (#1297)
* fix(frontmatter): prune vendor dirs at descent + bounded wall-clock with partial-state surfacing

Two production-grade fixes for the v0.38.2.0 wave (supersedes PR #1287).

Root cause Fix 1 (the bug that hung gbrain doctor on 216K-page brains): both
brain-writer.ts:walkDir and frontmatter.ts:collectFiles recursed into every
subdirectory without calling pruneDir, the canonical descent-time pruner
used by sync/extract/transcript-discovery since v0.35.5.0. On brains that
double as code workspaces, the walkers stat'd hundreds of thousands of
entries under node_modules / .git / .obsidian / *.raw / ops that isSyncable
filtered out at the leaf — paying the IO cost for nothing. Wiring pruneDir
at descent (with the v0.37.7.0 #1169 submodule-gitfile check) eliminates
the bulk of the wall-clock pain.

Fix 2 (codex outside-voice C1): AbortSignal.timeout cannot interrupt the
synchronous walker — readdirSync / lstatSync / readFileSync block the event
loop, so timer callbacks never fire mid-walk. The load-bearing wall-clock
bound is now a deadline check inside scanOneSource's visit callback
(Date.now() > opts.deadline). AbortSignal still works at source boundaries.

Shape changes (codex C2 + C4):
- ScanOpts: + deadline?: number, + dbPageCountForSource hook, + visitDir test seam
- PerSourceReport: + status: 'scanned' | 'partial' | 'skipped', + files_scanned, + db_page_count
- AuditReport: + partial: boolean, + aborted_at_source: string | null
- ok = grandTotal === 0 && !partial (a clean prefix from a timed-out scan
  no longer falsely reports clean)

walkDir + collectFiles now exported with an optional visitDir callback for
the regression suite. Production callers don't pass it.

Tests:
- test/brain-writer-walk-prune.test.ts (new, 12 cases): visitDir-based
  descent-time pruning assertions for both walkers. Pins the property
  output-based tests can't catch (isSyncable rejects vendor files at
  the leaf — so a test checking only output passes under the original bug).
- test/brain-writer-partial-scan.test.ts (new, 5 cases): deadline + partial
  state + ok-after-abort + numerator/denominator coverage. Uses deadline,
  NOT AbortSignal, since codex C1 proved abort can't interrupt sync.
- test/brain-writer.test.ts: existing "abort mid-scan" test refit to the
  new partial-state contract (per_source has 'skipped' entries instead of
  being empty — gives doctor visibility into which sources weren't checked).
- test/migrations-v0_22_4.test.ts: AuditReport fixture extended with the
  new required fields.

* fix(doctor): wire deadline + partial-state into frontmatter_integrity check

Adopts the v0.38.2.0 ScanBrainSources surface in doctor's frontmatter_integrity
check.

- AbortSignal.timeout(fmTimeoutMs) for between-source bound.
- deadline = Date.now() + fmTimeoutMs (the load-bearing mid-walk bound —
  codex C1 caught that AbortSignal alone can't fire inside the sync walker).
- GBRAIN_DOCTOR_FM_TIMEOUT_MS env override (default 30000ms; invalid values
  fall back to default rather than crash).
- Per-source DB denominator via SELECT COUNT(*) FROM pages WHERE source_id = $1
  AND deleted_at IS NULL (codex C3: deleted_at filter so soft-deleted pages
  don't inflate the count).
- Honest partial-render: "PARTIAL — scanned ~N files (source has ~M pages in
  DB), K issue(s) so far" instead of "scanned ~N of M pages" (codex C3 — the
  two populations are overlapping but not identical sets).
- "NOT SCANNED (timeout — run gbrain frontmatter validate <id>)" per skipped
  source so the user knows which sources didn't get checked.
- Catch block simplified to "unexpected error only" (codex D4 — the
  AbortError special case from PR #1287 was unreachable in a sync walker).

Tests: test/doctor-frontmatter-partial.test.ts (new, 11 cases) — structural
source-grep pins on every load-bearing render string plus the simplified-
catch contract. Behavioral coverage is deferred to the heavy script
(tests/heavy/frontmatter_scan_wallclock.sh, T6) because runDoctor calls
process.exit unconditionally and can't be driven from bun:test directly;
refactoring runDoctor to return rather than exit is a separate TODO.

* docs: v0.38.2.0 release notes, Phase 2 design sketch, heavy wall-clock smoke

- CHANGELOG.md: ELI10-lead-first release entry per CLAUDE.md voice rules.
  Names the user-visible behavior change, the per-source partial render, the
  performance numbers table, the "things to watch" caveats. Credits
  @garrytan-agents for PR #1287's diagnosis.
- VERSION + package.json: 0.37.11.0 -> 0.38.2.0.
- docs/architecture/frontmatter-scan-incremental.md: Phase 2 design sketch
  for DB-backed scan state. Schema, migration shape, writer paths
  (sync-side UPSERT + incremental scan + autopilot cycle phase), doctor
  reader, sequencing concerns, two-phase rollout plan. Starting point for
  the follow-up PR — sub-second steady-state doctor needs incremental
  state, but the schema migration carries its own contract surface
  (forward-reference bootstrap, schema-drift E2E, PGLite-vs-Postgres
  parity) that deserves its own focused PR.
- tests/heavy/frontmatter_scan_wallclock.sh (new, manual / nightly per
  tests/heavy/README.md): seeds a synthetic 60K-file brain (10K real + 50K
  under node_modules/) and asserts gbrain doctor completes in <15s with
  frontmatter_integrity: ok. Codex C7 caught that the original plan's
  1500-file budget was too small to be a meaningful guard — at that scale
  the test passes BEFORE AND AFTER the fix, proving nothing. 60K is the
  minimum that catches the descent-into-vendor-trees regression.

* fix: adversarial review followups — CLI hint, deadline-vs-await race, between-source breadcrumb

Codex adversarial review caught 4 real bugs in the v0.38.2.0 wave. All four
fixed before ship.

#1 (user-facing): `gbrain frontmatter validate` takes a filesystem PATH, not a
source id. Pre-fix the NOT SCANNED hint pointed users at
`gbrain frontmatter validate src-a` — which would fail with "no such
directory", breaking the very remediation this PR ships to give them. Fix:
render `src.source_path` instead.

#2 (correctness): between sources, `await dbPageCountForSource(src.id)` ran
unchecked. A slow query could blow past the deadline, then scanOneSource was
still called and returned `status='partial'` with `files_scanned=0` —
misleading ("partial scan" when actually zero files were scanned). Fix: add a
post-await deadline re-check; mark source + remainder as 'skipped' if the
budget already burned.

#3 (UX): when the outer-loop deadline check fired BETWEEN sources,
`aborted_at_source` stayed null and the doctor message said "PARTIAL SCAN"
with no source name. Fix: stamp `aborted_at_source` with the source we were
about to start.

#4 (correctness): the COUNT query had no per-call deadline. A wedged
Postgres pool could make a single COUNT hang past the budget and defeat the
wall-clock guarantee. Fix: Promise.race against the remaining deadline; on
timeout, resolve null and the post-await re-check (#2) marks the source
skipped.

Tests: 3 new regression cases in brain-writer-partial-scan.test.ts pinning
the fixed contracts (skipped-vs-partial under slow COUNT, hanging COUNT
within deadline, aborted_at_source before any source starts). 8648 pass /
0 fail across the full suite.

* docs(README): refresh production-brain stats — 8.2x pages, 5.6x people, 7.4x companies

Pre-update line (months stale): "17,888 pages, 4,383 people, 723 companies, 21
cron jobs running autonomously, built in 12 days."

Fresh counts from ~/git/brain (the wintermute production brain):
- pages: 17,888 → 146,646 (8.2x)
- people: 4,383 → 24,585 (5.6x)
- companies: 723 → 5,339 (7.4x)
- cron jobs running: 21 → 66 (113 total, 66 enabled per ~/git/wintermute/workspace/ops/cron-snapshot.json)

Dropped "built in 12 days" — at 146K pages the initial-velocity claim is
stale narrative that no longer matches the current scale story.

9a3ef3cda7 feat: pgGraph-inspired CI scaffolding wave (v0.37.4.0) (#1228)
Schema-migration matrix + fuzz harness + RSS budget gate + read-latency
under sync + sync lock regression + tests/heavy convention + nightly CI
workflow + BFS frontier cap on traverseGraph.

CI infra (T1-T7):
- tests/heavy/ directory convention + scripts/run-heavy.sh + bun run test:heavy
- tests/heavy/pg_upgrade_matrix.sh: walk pre-v0.13 + pre-v0.18 brain shapes
  forward to head via bootstrap → SCHEMA_SQL → migrations → verifySchema
- test/fuzz/{pure,mixed,filesystem}-validators.test.ts: 1000-run fast-check
  property tests across 8 trust-boundary validators
- scripts/check-fuzz-purity.sh: bun-bundle + grep guard, wired into verify
- tests/heavy/measure_rss.sh: in-memory PGLite workload + peak RSS measurement
  via /proc/self/status (Linux) or process.memoryUsage().rss fallback (macOS,
  refuses to write baseline)
- tests/heavy/read_latency_under_sync.sh: phase A baseline + phase B under
  parallel writer load, reports p50/p95/p99 + delta_pct
- tests/heavy/sync_lock_regression.sh: N concurrent gbrain sync against one
  DB, asserts 1 winner + N-1 lock-busy + zero leaked gbrain_cycle_locks rows
- .github/workflows/heavy-tests.yml: cron '17 8 * * *' + heavy-tests label
  trigger + Postgres service + artifact upload on failure

Engine (T8):
- BrainEngine.traverseGraph opts gain frontierCap?: number + onTruncation?:
  (info: TruncationInfo) => void callback. Return shape preserved
  (Promise<GraphNode[]>) for MCP wire stability.
- Postgres CTE: parenthesized LIMIT N ORDER BY (slug, id) inside recursive term.
- PGLite: same SQL with positional params.
- Per-call callback closure — not engine-instance state — so concurrent
  traversals on the same engine don't cross-talk. 5 contracts pinned in
  test/regressions/v0_36_frontier_cap.test.ts.

Three plan-review passes ran before any code: CEO scope review (Approach C),
Eng dual-voice review (Claude subagent + Codex), and Codex 2nd-pass against
the revised plan. The 2nd pass caught issues the first two missed (Bun ESM
vs require.cache; engine-instance metadata stomping under concurrency;
fixture-size inconsistency). All addressed.
