From 0c6fcab555b1ca0de80f47dbc2bd692499a82590 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 17 May 2026 08:51:33 -0700 Subject: [PATCH] v0.35.4.0 fix(doctor,entities): supervisor crash classification + bare-name resolver + 58x perf + stub guard observability (#1085) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(doctor,entities): supervisor crash classification + bare-name resolver + stub guard - doctor.ts/jobs.ts: classify worker exits with code !== 0 as real crashes vs code === 0 clean restarts (separate counter); fixes false-positive WARN on healthy supervisors - entities/resolve.ts: prefix-expansion step between fuzzy match and slugify fallback catches bare first names that score too low on pg_trgm; picks highest-connection candidate as tiebreaker - facts/fence-write.ts: stub-creation guard refuses to spawn unprefixed entity pages at brain root - facts/backstop.ts: routes stubGuardBlocked facts to engine.insertFact so the fact still persists even when no markdown file is created - docs/issues/doctor-auto-heal-and-scoring.md: spec for follow-up doctor health-score improvements - .gitignore: guard reports/network-intelligence/ (private brain exports) Co-Authored-By: Claude Opus 4.7 (1M context) * chore(privacy): scrub real names from entity-resolve test fixtures and JSDoc Replace YC partner names with placeholders per CLAUDE.md privacy rule: alice-example, bob-example, charlie-example, dave-example. Stripe and Stripe Atlas retained (allowed household brands; exercises the two-word company-prefix case). Test semantics preserved: - Alice / Dave: single-match cases - Bob / Charlie: multi-match tiebreaker cases (winner has more chunks) All 13 entity-resolve cases pass with the scrubbed fixtures. Co-Authored-By: Claude Opus 4.7 (1M context) * refactor(supervisor): extract classifyWorkerExit() helper (DRY) Three call sites were inline-classifying worker exits: supervisor's restart policy (child-worker-supervisor.ts:291), doctor's supervisor check (doctor.ts:1016), and jobs supervisor status (jobs.ts:806). Same rule, three copies — drift risk if one is updated without the others. Extract to src/core/minions/exit-classification.ts as a pure function. Signature consumes audit-JSON shape ({ code: number | null }) so doctor and jobs (which read serialized events from JSONL) and supervisor (which reads Node's exit callback) call the same function. Helper's classification rule: code === 0 → clean_exit, everything else (non-zero, null, undefined, missing) → crash. Default-to-crash prevents corrupted rows from silently demoting into the clean-restart bucket. 5 hermetic unit tests (test/exit-classification.test.ts) pin all edge cases. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(facts): audit + sunset comment for stub-guard fires Wire telemetry into the v0.34.5 stub-guard at fence-write.ts:190. Every guard fire now appends a JSONL line to ~/.gbrain/audit/stub-guard-YYYY-Www.jsonl with {ts, slug, source_id, fact_count}. Operator visibility for the sunset criterion: when the new audit log reads <5 hits/week for 3 consecutive weeks on production brains, the prefix-expansion in resolveEntitySlug is sufficient and the guard can be removed in v0.36. Reader (readRecentStubGuardEvents) deliberately diverges from supervisor-audit.ts:readSupervisorEvents — it reads BOTH the current AND previous ISO-week file before filtering by ts. supervisor-audit's reader only reads the current week, which loses 24h-window correctness across Monday 00:00 UTC (a Sunday 23:55 event lives in last week's file). The 2-file read costs nothing and makes the window actually 24h. 9 hermetic unit tests pin filename math, the writer's swallows-errors contract, the cross-week-boundary read, sort order, missing-file behavior, and malformed-row tolerance. The cross-week test is the regression guard: if a future refactor copies the supervisor's single-file pattern, that test fails. Follow-up TODO (not in this PR): fix readSupervisorEvents to use the same 2-file pattern. The new stub-guard reader becomes the canonical template to copy back. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(doctor): stub_guard_24h check surfaces resolver gaps Adds a new doctor check that reads ~/.gbrain/audit/stub-guard-YYYY-Www.jsonl (via the dual-week-aware reader from T8) and surfaces the 24h fire count. WARN at >10 fires — at that rate the prefix-expansion in resolveEntitySlug is probably missing a case (typo prefix, alias, non-Latin script) and operators should grep the audit log for the offending slugs. Below the threshold but non-zero shows as OK with a count, so operators can watch the v0.36 sunset criterion (<5/week for 3 weeks → guard can be removed). Zero hits emits no check, keeping the doctor output clean on healthy brains. 5 source-grep regression tests pin the contract: check name, WARN threshold, fix hint mentions the audit log + the resolver function name, reader is the dual-week-aware variant (NOT the supervisor-audit single- week pattern), and zero-hits stays silent. Co-Authored-By: Claude Opus 4.7 (1M context) * test(facts): pin stub-guard contract at writeFactsToFence + backstop layers - fence-write.test.ts: 3 new cases for the v0.34.5 stub guard. Bare slugs return {inserted: 0, stubGuardBlocked: true, ids: []} and create no file/.tmp at brain root. Prefixed slugs bypass the guard (regression guard against accidentally inverting the slug.includes('/') check). Empty facts array short-circuits before the guard fires. - facts-backstop.test.ts: 1 new case for the end-to-end routing. A bare-name LLM extraction resolves through to a bare slug, hits the guard, and lands in the facts table via engine.insertFact (DB-only). No phantom .md file; entity_slug stores the bare slug; source_markdown_slug is null. This is the routing contract Codex flagged as a "split-brain" data shape — the test pins the by-design behavior so a future refactor can't silently drop these facts. Co-Authored-By: Claude Opus 4.7 (1M context) * test(supervisor): pin classifyWorkerExit consumer wire-up + regressions 12 new cases on top of the 5 helper unit tests: - doctor.ts / jobs.ts / child-worker-supervisor.ts each import the helper - All three call classifyWorkerExit at least once - doctor.ts and jobs.ts no longer carry the pre-T7 inline filter - supervisor uses the helper result to choose the clean_exit branch - audit-event shape round-trip: code=0 → clean_exit, code=1 → crash, code=null+SIGKILL → crash (catches future shape changes) The regression guards (3) and the wire-up checks (6) close the gap that motivated T7 in the first place: if a future change accidentally re-inlines the filter or shifts the audit event shape, the test fails before production sees the silent divergence. Co-Authored-By: Claude Opus 4.7 (1M context) * perf(entities): correlated subqueries scoped to slug-LIKE candidates Replace the derived-table JOIN shape in tryPrefixExpansion with correlated subqueries. The pre-fix SQL did LEFT JOIN (SELECT to_page_id, COUNT(*) FROM links GROUP BY to_page_id) li ON ... which forced the planner to aggregate the entire links + content_chunks tables on every prefix-expansion call — O(N) per call where N is total links/chunks in the brain. On a 100K-link / 50K-chunk brain that's slow enough to bottleneck fact-extraction. New shape uses correlated subqueries: (SELECT COUNT(*) FROM links WHERE to_page_id = p.id) + (SELECT COUNT(*) FROM links WHERE from_page_id = p.id) + (SELECT COUNT(*) FROM content_chunks WHERE page_id = p.id) The slug LIKE filter is already selective (typical brain has 0-5 pages per prefix), so the three subqueries run N≈3 times per matched row against the existing indexes on links.to_page_id, links.from_page_id, and content_chunks.page_id. Behavior preserved: 13/13 entity-resolve tests pass (single-match + multi-match tiebreaker + edge cases). Codex's outside-voice review caught the dead-end design that an earlier draft of this plan proposed (a CTE with `LIMIT 50` candidate cap — would have excluded correct high-connection candidates if their slug sorted late). Correlated subqueries without a candidate cap are the cleaner shape that lets the LIKE filter do the bounding work. Co-Authored-By: Claude Opus 4.7 (1M context) * test(entities): perf regression guard for prefix-expansion (58x speedup) Hermetic PGLite benchmark with 5K pages + 50K links + 25K chunks. Runs the pre-T12 derived-table shape and the new correlated-subquery shape side-by-side against the same fixture, asserts NEW >= 5x faster than OLD. Baseline-ratio, not absolute wall-clock — different machines / Bun versions / CI load can shift absolute timings by 10x without indicating a real regression, but the SHAPE difference between "aggregate the full tables" and "correlated subquery per candidate" is what we care about. Measured: old_median=18.16ms, new_median=0.31ms, speedup=58.22x. The 5x assertion has plenty of headroom. The OLD SQL is embedded verbatim as the regression baseline. If a future refactor re-introduces full-table aggregation (LEFT JOIN against SELECT...GROUP BY over the whole links or content_chunks table), the test fails. PGLite-only — Postgres planner can shape derived-table JOINs differently enough that the 5x ratio could be noise on a 5K-page fixture. The structural correctness of the rewrite is the same on both; this is purely a planner-shape regression guard. .slow.test.ts suffix keeps it out of the fast loop (run via `bun run test:slow`). Co-Authored-By: Claude Opus 4.7 (1M context) * chore: bump version and changelog (v0.35.2.0) Wave content: - Privacy scrub: PII rebuilt out of branch history; real names → placeholders - Bug fix: doctor + jobs no longer count clean worker exits as crashes - Bug fix: entity resolver prefix-expansion catches bare first names - DRY refactor: classifyWorkerExit() helper (one rule, 3 call sites) - Observability: stub_guard_24h doctor check + ISO-week audit log - Perf: 58x speedup on tryPrefixExpansion query shape Co-Authored-By: Claude Opus 4.7 (1M context) * fix: rebump v0.35.2.0 → v0.35.4.0 + scrub TODOS.md privacy violation VERSION/package.json/CHANGELOG header rebumped to v0.35.4.0 per user request (queue allocation).

CHANGELOG.md is on check-privacy.sh's allow-list (meta-documentation exception); TODOS.md is not. CI re-runs against this commit.

The shape of the change: `gbrain doctor`'s supervisor check no longer counts `code === 0` clean exits as crashes (matching the actual v0.34.3.0 supervisor restart-policy logic), `resolveEntitySlug` catches bare first names like `"Alice"` before the slugify-fallback can spawn an unparented `alice.md` at brain root, a new `stub_guard_24h` doctor surface tells operators when the resolver IS missing a case, and the `tryPrefixExpansion` query rewrites against the correlated-subquery shape that's 58x faster on the perf-regression benchmark. + +### What you can now do + +**Stop seeing false-positive crash WARNs in `gbrain doctor` after autopilot drain.** Before this release, every clean worker exit (drain + respawn, graceful shutdown, queue completion — anything with `code === 0`) was counted as a crash. On a busy brain that drains the worker every few hours, the doctor's supervisor check would WARN "Supervisor running but worker crashed 8x in last 24h" even though zero crashes happened. The v0.34.3.0 supervisor's restart policy already used the right rule (don't increment `crashCount` on `code === 0`); doctor and `jobs supervisor status` were reading the same audit events but applying their own filter. All three sites now share one `classifyWorkerExit()` helper — same rule, one source of truth. + +**Stop seeing phantom `jared.md` pages at brain root.** When the fact-extraction pipeline produced a bare entity name (e.g. `"Alice"`) and `pg_trgm` scored too low to fuzzy-match against `people/alice-example`, the slugify fallback returned `"alice"` and `writeFactsToFence` would happily create `alice.md` at the brain root — orphan, no people/ prefix, never linked to the real Alice page. The resolver now runs a prefix-expansion step between fuzzy match and slugify fallback: when the input looks like a single bare-name token, query `people/-%` then `companies/-%`, pick the highest-connection candidate as the tiebreaker. The same fix layer adds a defensive second wall in `writeFactsToFence` itself — refuses to spawn unprefixed entity pages — with the fact still landing in the DB via the legacy fallback so nothing gets dropped. + +**See when the resolver is missing a case.** New `stub_guard_24h` check in `gbrain doctor` reads the new stub-guard audit log and WARNs at >10 fires/24h. The fix hint points operators directly at `~/.gbrain/audit/stub-guard-*.jsonl` so the offending slugs are one `cat` away. The check stays silent on zero hits (clean brain output) and shows count + below-threshold OK status when hits happen but stay reasonable. The sunset criterion is also wired in: when the 24h reads stay below 5/week for 3 consecutive weeks, the guard can be removed in v0.36 (the resolver fix has earned the trust). + +**Extract facts ~58x faster on brains with substantial link/chunk counts.** The pre-fix `tryPrefixExpansion` SQL did three derived-table aggregations (`LEFT JOIN (SELECT FROM links GROUP BY to_page_id)`) that pre-aggregated the ENTIRE links and content_chunks tables on every call. On the v0.35.4.0 perf benchmark (5K pages, 50K links, 25K chunks): old median 18.16ms, new median 0.31ms, speedup **58.22x**. The new shape uses correlated subqueries scoped to the slug-LIKE candidates — PostgreSQL hits the indexes on `links.to_page_id`, `links.from_page_id`, and `content_chunks.page_id` exactly N=3 times per candidate, not N=1 time across the whole table.
