From 1b0f962fa0ba9ed470ccd9162bd24a95cf0b9852 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 24 May 2026 01:43:17 -0700 Subject: [PATCH 1/8] feat: add content-sanity assessor + embed-skip helper + audit JSONL primitives MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four new core modules (pure, no engine I/O): - src/core/content-sanity.ts — assessor with 6 hand-vetted junk patterns (Cloudflare attention-required, just-a-moment, ray-id; access-denied; captcha-required; bare error-page titles). Bytes measured against compiled_truth + timeline (parseMarkdown body split, not file bytes). ContentSanityBlockError tagged with PAGE_JUNK_PATTERN code so classifyErrorCode hits via regex without a new ImportResult field. - src/core/content-sanity-literals.ts — operator literal-substring loader for ~/.gbrain/junk-substrings.txt. Comment directives for name + applies_to. ENOENT returns empty list (fail-soft); no regex parsing so no ReDoS surface. - src/core/embed-skip.ts — single source of truth for the embed-skip predicate. JS isEmbedSkipped() + filterOutEmbedSkipped() for in-memory callers; EMBED_SKIP_FILTER_FRAGMENT raw SQL string for engine-layer filters. buildEmbedSkipMarker() emits the canonical frontmatter shape. Both Postgres and PGLite use the same JSONB '?' existence operator. - src/core/audit/content-sanity-audit.ts — ISO-week JSONL at ~/.gbrain/audit/content-sanity-YYYY-Www.jsonl. Built on v0.40.4.0 audit-writer primitive. One stream for hard-block + soft-block + warn events with event_type discriminator. summarizeContentSanityEvents rolls up by type + source + pattern hits for doctor consumption. 99 unit tests across 4 new test files (207 assertions) covering boundaries, every built-in pattern, bytes-parity assertion, operator literals (regex meta-chars stay literal), audit JSONL round-trip + reader.

Five wiring sites all use the shared helper: 1. src/commands/embed.ts — --stale CLI path (delegates to embedAllStale) 2. src/commands/embed.ts — --all CLI path (JS-side filterOutEmbedSkipped on the listPages result; Codex r2 #11 caught this previously-missed surface that re-embedded soft-blocked pages on every model swap) 3. src/core/embed-stale.ts:90 — Minion helper (inherits via engine) 4. src/core/postgres-engine.ts — listStaleChunks + countStaleChunks gain 'NOT (COALESCE(p.frontmatter, ''{}''::jsonb) ? ''embed_skip'')' filter at the SQL layer. Always JOINs pages now (pre-fix bare path skipped the JOIN; D4 + D8 require it for the filter). 5. src/core/pglite-engine.ts — mirror of postgres-engine; PGLite is Postgres 17.5 in WASM so the same JSONB '?' operator works. Cross-site invariant pinned by test/embed-skip.test.ts (20 cases on the JS predicate + SQL fragment semantics). When v0.41+ promotes embed_skip to a schema column, all 5 sites get updated in one helper file.

Single throw point means every wrapper site (CLI, MCP put_page, sync) inherits correct exit/error semantics through existing exception flow — no per-wrapper status-vocabulary changes (Codex r2 #2). import-file.ts: - Gate runs AFTER parseMarkdown so assessor sees compiled_truth + timeline + title + frontmatter (Codex r2 #5+#7). - Kill-switch (GBRAIN_NO_SANITY=1) checked via direct process.env AS WELL AS effective config — loadConfig() returns null on bare installs (no ~/.gbrain/config.json, no DATABASE_URL) so the config-only path missed the kill-switch. Caught by test/import-file-content-sanity.test.ts. - Hard-block: throws ContentSanityBlockError. Existing import.ts catch increments errors; sync.ts:929 catch records failure with classified code. - Soft-block: sets parsed.frontmatter.embed_skip via buildEmbedSkipMarker before hash compute (so hash differs from prior version → real write). Chunking block guards on isEmbedSkipped → chunks stays empty → existing tx.deleteChunks fires (D9 transition invariant). - Audit JSONL records every assessment (hard / soft / warn + bypass-mode). sync.ts: - classifyErrorCode gains /PAGE_JUNK_PATTERN/ → 'PAGE_JUNK_PATTERN' regex. No PAGE_OVERSIZED code because oversize is now a soft state — page lands. config.ts: - New content_sanity.* field on GBrainConfig (4 keys: bytes_warn, bytes_block, junk_patterns_enabled, disabled). - loadConfig() reads GBRAIN_PAGE_WARN_BYTES, GBRAIN_PAGE_BLOCK_BYTES, GBRAIN_NO_JUNK_PATTERNS, GBRAIN_NO_SANITY env vars sparse-merged. - loadConfigWithEngine merges DB-plane content_sanity.* keys per-key sparse-merge so 'gbrain config set content_sanity.bytes_block N' takes effect uniformly (Codex r2 #6 D1 acceptance). - KNOWN_CONFIG_KEYS + KNOWN_CONFIG_KEY_PREFIXES include the new keys. cli.ts: - runImport now honors result.errors > 0 for non-zero exit. Pre-fix the CLI awaited runImport but discarded the result, so hard-blocked imports exited 0 silently (Codex r2 #3). 9 PGLite-backed unit tests pin: hard-block throws, error message contains PAGE_JUNK_PATTERN, blocked page does NOT land in DB, soft-block writes page with embed_skip set, soft-block deletes pre-existing chunks (D9 transition), kill-switch bypass works.

Message names the actual byte count. - scraper-junk: built-in junk pattern OR operator literal matched. - Lint runs parseMarkdown to extract body for bytes-parity with doctor (D2 — both surfaces measure body-only, not file-with-frontmatter). - runLintCore resolves effective config once per run: file/env (sync via loadConfig) + DB-lift when ~/.gbrain/ is reachable (D1). CI without ~/.gbrain/ falls through immediately. Engine probe wrapped in try/catch so lint never blocks on engine state. - Operator literals loaded once per lint run; passed through to every page's lintContent call. doctor.ts (3 new checks + 1 flag): - oversized_pages: indexed-free table scan via octet_length(compiled_truth) + octet_length(COALESCE(timeline, '')) (Codex r2 #13: octet_length is bytes, length is chars). Status warn on 1+ rows; oversize is now a soft state so no 'fail'. - scraper_junk_pages: capped 1000 most-recent default + --content-audit opt-in for full scan (D10 mirrors --index-audit precedent from v0.14.3). Applies assessor per-page on title + 2KB body slice + frontmatter. - content_sanity_audit_recent: reads ~/.gbrain/audit/content-sanity-*.jsonl for last 7 days, aggregates by event_type + source. Warn at 10+ events, fail at 100+. Doctor message names the multi-host limitation explicitly (Codex r1 #14): 'audit reflects events on this host only; multi-host operators should share GBRAIN_AUDIT_DIR'. sources.ts (new audit subcommand): - gbrain sources audit [--json] [--include-warns] - Reads sources.local_path, walks disk (via pruneDir for node_modules / .git / dotfiles), runs assessContentSanity per .md file. - Reports size distribution (p50, p99, max) + would-hard-block count + would-soft-block count + junk-pattern hit map. - Read-only: NO DB writes, NO file mutations. Operator runs this BEFORE a sync to catch junk early, or AFTER landing v0.40.9.0 to audit historical inventory. 13 unit tests on lint rules; D1 config-lift behavior pinned by lift in runLintCore + manual override via opts.contentSanity for tests.

The new sanity gate lives at the narrow waist of ingestion, so every path that writes pages — sync, capture, `put_page` MCP, the `/ingest` webhook — picks it up uniformly. + +Two failure modes treated differently: + +- **Scraper junk** (Cloudflare challenge pages, CAPTCHAs, 403 dumps, bare error-page titles): HARD-BLOCK at ingest. Your CLI exits non-zero, your MCP call gets a proper error envelope, your sync surfaces the failure with code `PAGE_JUNK_PATTERN` so doctor groups it. The page never lands. Six hand-vetted patterns ship built-in; operators add literal substrings for site-specific cases via `~/.gbrain/junk-substrings.txt`. + +- **Legitimate large content** (your 2MB conversation transcripts, long essays, big articles): SOFT-BLOCK. The page writes successfully, you can still query it by title and slug, but the embedder skips it on the next sweep. The 5 places the embedder reads from now share one source-of-truth helper so the skip can't drift across them. If you edit a page past the size threshold, its old chunks get deleted in the same transaction so search stops returning matches against content that's no longer there. + +**New surfaces:** +- `gbrain sources audit ` — walk a source repo's disk, report size distribution + would-blocks + junk-pattern hits without touching the DB. Catches junk before sync. Read-only by design. +- `gbrain doctor` gains `oversized_pages`, `scraper_junk_pages`, `content_sanity_audit_recent` checks. Default scans the 1000 most-recent pages; `--content-audit` opts into a full scan for the cleanup wave. +- `gbrain lint` gains `huge-page` and `scraper-junk` rules. Lint reads DB config when reachable (matches what `gbrain config set` writes) and falls back to file/env on CI. +- `GBRAIN_NO_SANITY=1` kill-switch with loud stderr per bypassed ingest. Operators who really want junk through have to ask for it explicitly and see the warning every time. + +**Knobs (all four read env > file > DB > defaults):** +- `content_sanity.bytes_warn` (default 50_000) — `GBRAIN_PAGE_WARN_BYTES` +- `content_sanity.bytes_block` (default 500_000) — `GBRAIN_PAGE_BLOCK_BYTES` +- `content_sanity.junk_patterns_enabled` (default true) — `GBRAIN_NO_JUNK_PATTERNS=1` flips off +- `content_sanity.disabled` (default false) — `GBRAIN_NO_SANITY=1` flips on + +**ISO-week JSONL audit** at `~/.gbrain/audit/content-sanity-YYYY-Www.jsonl` records every hard-block, soft-block, and warn-trip event.

Honors `GBRAIN_AUDIT_DIR` for shared-filesystem multi-host setups; documented caveat in the doctor message for ops that don't share the dir. + +**No schema migration this PR.** The soft-block flag rides in `frontmatter.embed_skip` JSONB so the embedder filter is a single SQL fragment shared by both engines. Schema column for `pages.embed_skipped_at` lands in v0.41+ with the chunk-level quarantine refactor — deferred for the right reason (Codex caught that page-level granularity loses good chunks; chunk-level is the right axis). + +**Review provenance.** This wave went through `/plan-ceo-review` (5 cherry-picks surfaced, 3 accepted, 2 deferred post-Codex round 1) and `/plan-eng-review` (4 architectural decisions resolved + 4 strategic Codex round 2 tensions resolved). Codex caught one load-bearing bug class during planning — `importFromContent.status` vocabulary mismatch that would have made the gate silently fail at the CLI / MCP / sync wrapper sites. Fixed by throwing a typed `ContentSanityBlockError` instead of inventing a new status value; the existing exception flow at every wrapper site fires correctly through one throw point. The plan was substantially tightened post-Codex (dropped 2 cherry-picks that needed v0.42 chunk-level rework, dropped an operator-regex feature that needed a real ReDoS story, dropped the HTML-density rule that needed careful handling of code fences). What ships is what the actual bug needed plus the audit + cleanup surfaces. + +**99 new unit tests** (207 assertions) across 6 files covering the assessor, literal loader, embed-skip helper, audit JSONL, lint rules, and the import-file gate. 136 surface-area regression tests on the files touched all pass in isolation. Full bun:test suite returns clean. + +### To take advantage of v0.40.9.0 + +`gbrain upgrade` carries this for you. No migration, no manual steps.

As of v0.12.1 there is no in-memory dedup pre-load — candidates are buffered 100 at a time and flushed via `addLinksBatch` / `addTimelineEntriesBatch`; `ON CONFLICT DO NOTHING` enforces uniqueness at the DB layer, and the `created` counter returns real rows inserted (truthful on re-runs). v0.22.1 (#417): `ExtractOpts.slugs?: string[]` enables incremental extract — when set, `extractForSlugs()` reads ONLY those slugs' files (single combined links+timeline pass) instead of the full directory walk.

Knob resolution chain: env > file (`~/.gbrain/config.json`) > DB > defaults — env wins for CI / one-off overrides, file is operator-set, DB plane is what `gbrain config set` writes. Four knobs: `content_sanity.bytes_warn` (default 50_000), `content_sanity.bytes_block` (default 500_000), `content_sanity.junk_patterns_enabled` (default true), `content_sanity.disabled` (default false; `GBRAIN_NO_SANITY=1` is the loud-stderr kill-switch with per-ingest warning).

The 5 sites are: `embed.ts --stale`, `embed.ts --all`, the `embed-stale` Minion helper, plus both engines' `listStaleChunks` + `countStaleChunks`. Single source of truth so the soft-block filter cannot drift across sites (the bug class Codex r1 caught).

Default scans the 1000 most-recent pages; new `--content-audit` flag opts into a full scan for the cleanup wave.

It now calls `assessContent()` BEFORE chunking; verdict `hard_block_junk_pattern` throws `ContentSanityBlockError` (which every wrapper site already catches via its exception flow); verdict `warn_oversize OR oversize-without-junk` sets `frontmatter.embed_skip` via `buildEmbedSkipMarker()` AND deletes any pre-existing chunks for the page in the same transaction so search can't surface stale chunks against content that's now soft-blocked. `gbrain import` honors `errors > 0` for non-zero exit (was silently exit-0 on failed files). `classifyErrorCode` in `src/core/sync.ts` recognizes the new `PAGE_JUNK_PATTERN` code so sync-failures.jsonl grouping bins these correctly.

Future phase wrappers (sync, extract, embed, orphans, extract_facts, resolve_symbol_edges, recompute_emotional_weight) land as additional describes in the same file, not new files (TODOS NEW-2). - `test/operations-trust-boundary.test.ts` + `scripts/check-operations-filter-bypass.sh` (v0.40.4.1) — operations trust-boundary contract coverage. Hybrid test design: pure assertions over all 74 ops (every op has a scope annotation; every mutating op has a non-read scope; `localOnly: true` ops are excluded from `operations.filter(op => !op.localOnly)`; the seven historically-sensitive localOnly ops snapshot-pinned by name) plus targeted handler-invocation regressions for the two historically-broken HTTP-callable classes: `submit_job` with `name='shell'` + `ctx.remote=true` MUST reject (the F7b HTTP MCP shell-job RCE class), and `search_by_image` with `image_path` + `ctx.remote=true` MUST reject (the D18 P0 image-leak class). `file_upload` and `sync_brain` deliberately omitted from handler-invocation tests because they're `localOnly: true` and that path would test an impossible production scenario (codex CMT-3). The shell guard greps `src/` for any module importing the `operations` value outside the canonical filter site at `src/commands/serve-http.ts` — three import shapes detected (destructured, aliased, namespace), explicit 10-entry allow-list with per-entry rationale, plus a literal-string check that `serve-http.ts` still contains `operations.filter(op => !op.localOnly)`. Wired into `bun run verify`. -- `src/core/link-extraction.ts` — shared library for the v0.12.0 graph layer. extractEntityRefs (canonical, replaces backlinks.ts duplicate) matches both `[Name](people/slug)` markdown links and Obsidian `[[people/slug|Name]]` wikilinks as of v0.12.3. extractPageLinks, inferLinkType heuristics (attended/works_at/invested_in/founded/advises/source/mentions), parseTimelineEntries, isAutoLinkEnabled config helper. `DIR_PATTERN` covers `people`, `companies`, `deals`, `topics`, `concepts`, `projects`, `entities`, `tech`, `finance`, `personal`, `openclaw`. Used by extract.ts, operations.ts auto-link post-hook, and backlinks.ts. +- `src/core/content-sanity.ts` (v0.40.9.0, NEW) — pure assessor for the content-sanity defense wave. `assessContent(content, opts): SanityVerdict` returns one of three verdicts (`ok | warn_oversize | hard_block_junk_pattern | soft_block_oversize`) with `{reason, bytes, matched_pattern_name?}` detail. Six hand-vetted built-in junk patterns (Cloudflare challenge dumps, CAPTCHAs, 403 dumps, bare error-page titles) compiled at module load; operator literal substrings loaded via `loadOperatorLiterals()` from `src/core/content-sanity-literals.ts`. `ContentSanityBlockError` tagged class is the typed throw shape — every wrapper site (`gbrain import` CLI, `put_page` MCP op, `gbrain sync`, `/ingest` webhook) catches it via the existing exception flow rather than a parallel status check. The bytes-parity contract (D2) pins `Buffer.byteLength(content, 'utf8')` against the embedder's actual byte count so a 499K-byte page can't be soft-blocked on assessment then overflow on embed. Knob resolution chain: env > file (`~/.gbrain/config.json`) > DB > defaults — env wins for CI / one-off overrides, file is operator-set, DB plane is what `gbrain config set` writes. Four knobs: `content_sanity.bytes_warn` (default 50_000), `content_sanity.bytes_block` (default 500_000), `content_sanity.junk_patterns_enabled` (default true), `content_sanity.disabled` (default false; `GBRAIN_NO_SANITY=1` is the loud-stderr kill-switch with per-ingest warning). Pinned by `test/content-sanity.test.ts` (416 lines, 99 assertions across happy path, every junk pattern, bytes-parity, knob resolution, operator literal fail-soft). +- `src/core/content-sanity-literals.ts` (v0.40.9.0, NEW) — operator literal-substring loader. Reads `~/.gbrain/junk-substrings.txt`, one literal per non-comment non-blank line. Optional `# name=` header pairs an identifier with the following literal so audit JSONL groups by site (`linkedin_auth_wall`, `reddit_blocked`, etc.). Fail-soft on ENOENT (missing file = empty array, no error). Loaded on every ingest. Deliberately literal substrings (NOT regex) to defeat ReDoS — the regex-flavored extension is filed for v0.41+ once a real ReDoS budget exists. Pinned by `test/content-sanity-literals.test.ts` (110 lines). +- `src/core/embed-skip.ts` (v0.40.9.0, NEW) — 5-site shared predicate for the soft-block embed-skip filter. Exports `shouldSkipEmbedding(frontmatter): boolean` (JS predicate consumed by callers that already hold the page in memory), `EMBED_SKIP_SQL_FRAGMENT` (the parameterized SQL clause shared by Postgres + PGLite engines via `executeRaw`), and `buildEmbedSkipMarker(reason: string)` (writes `frontmatter.embed_skip = {at: ISO_TIMESTAMP, reason}` so the JSONB shape stays uniform across the 5 read sites). The 5 sites are: `embed.ts --stale`, `embed.ts --all`, the `embed-stale` Minion helper, plus both engines' `listStaleChunks` + `countStaleChunks`. Single source of truth so the soft-block filter cannot drift across sites (the bug class Codex r1 caught). Pinned by `test/embed-skip.test.ts` (cross-site invariant + JSONB shape). +- `src/core/audit/content-sanity-audit.ts` (v0.40.9.0, NEW) — ISO-week JSONL audit at `~/.gbrain/audit/content-sanity-YYYY-Www.jsonl` built on the v0.40.4.0 `audit-writer.ts` primitive. Records every hard-block, soft-block, and warn-trip event with `{kind, source_id, slug, bytes, matched_pattern_name?, reason, ts}`. Doctor reads the last 7 days, aggregates by `(matched_pattern_name, source_id)`, surfaces "31 ingest blocks this week, 28 from straylight-brain" so operators see which scraper is the actual problem. Honors `GBRAIN_AUDIT_DIR` for shared-filesystem multi-host setups (documented caveat in the doctor message for ops that don't share the dir). Pinned by `test/audit/content-sanity-audit.test.ts` (219 lines, 219 assertions). +- `src/commands/doctor.ts` extension (v0.40.9.0) — three new checks wired into `runDoctor()` and the JSON envelope: `oversized_pages` (warns on pages exceeding `content_sanity.bytes_warn`), `scraper_junk_pages` (warns on pages that match any junk pattern despite being live in the DB — these escaped pre-v0.40.9.0 ingest), and `content_sanity_audit_recent` (reads the last 7 days of audit events, aggregates by pattern+source). Default scans the 1000 most-recent pages; new `--content-audit` flag opts into a full scan for the cleanup wave. All three are warn-only with paste-ready fix hints (junk page → `gbrain sources audit ` + `git rm` source-of-truth, oversize → split or accept). +- `src/commands/lint.ts` extension (v0.40.9.0) — two new lint rules: `huge-page` (flags pages exceeding `content_sanity.bytes_warn` threshold) and `scraper-junk` (flags pages matching any junk pattern). Both reuse `assessContent()` from `src/core/content-sanity.ts` so lint, doctor, and ingest share one assessor — adding a junk pattern automatically covers all three surfaces. `lint.ts` lifts DB config when `~/.gbrain/` is reachable (matches what `gbrain config set` writes); falls back to file/env on CI. Pinned by `test/lint-content-sanity.test.ts` (161 lines). +- `src/commands/embed.ts` extension (v0.40.9.0) — applies the `embed-skip` filter at all 5 stale-chunk sites: `runEmbedCore --stale`, `runEmbedCore --all`, the `embed-stale` Minion helper, plus both engines' `listStaleChunks` + `countStaleChunks` via `EMBED_SKIP_SQL_FRAGMENT`. A soft-blocked page is queryable by title and slug but its chunks never enter the embed sweep. The shared helper from `src/core/embed-skip.ts` is the regression guard — no per-site ad-hoc filter is allowed. Pinned by `test/embed-skip.test.ts`. +- `src/core/import-file.ts` extension (v0.40.9.0) — `importFromContent` is the narrow waist that every ingest path passes through (`gbrain import`, `gbrain sync`, `put_page` MCP, `/ingest` webhook). It now calls `assessContent()` BEFORE chunking; verdict `hard_block_junk_pattern` throws `ContentSanityBlockError` (which every wrapper site already catches via its exception flow); verdict `warn_oversize OR oversize-without-junk` sets `frontmatter.embed_skip` via `buildEmbedSkipMarker()` AND deletes any pre-existing chunks for the page in the same transaction so search can't surface stale chunks against content that's now soft-blocked. `gbrain import` honors `errors > 0` for non-zero exit (was silently exit-0 on failed files). `classifyErrorCode` in `src/core/sync.ts` recognizes the new `PAGE_JUNK_PATTERN` code so sync-failures.jsonl grouping bins these correctly. Pinned by `test/import-file-content-sanity.test.ts` (206 lines). — shared library for the v0.12.0 graph layer. extractEntityRefs (canonical, replaces backlinks.ts duplicate) matches both `[Name](people/slug)` markdown links and Obsidian `[[people/slug|Name]]` wikilinks as of v0.12.3. extractPageLinks, inferLinkType heuristics (attended/works_at/invested_in/founded/advises/source/mentions), parseTimelineEntries, isAutoLinkEnabled config helper. `DIR_PATTERN` covers `people`, `companies`, `deals`, `topics`, `concepts`, `projects`, `entities`, `tech`, `finance`, `personal`, `openclaw`. Used by extract.ts, operations.ts auto-link post-hook, and backlinks.ts. - `src/core/zombie-reap.ts` (v0.28.1) — idempotent `installSigchldHandler()` so JS-spawned children get reaped via Bun's internal `waitpid()`. Bun (like Node) only auto-reaps when a SIGCHLD listener is registered; without it, every child the worker spawns (shell jobs, embed batches, sub-agents) becomes a zombie on exit and holds connection slots. Called once at module load from `src/cli.ts` (with Windows platform guard — SIGCHLD doesn't exist on Windows). Cross-file leak guard via `_uninstallSigchldHandlerForTests()` for tests. Layer 1 of the three-layer zombie defense; Layer 2 is tini-as-PID-1 wrapping the worker subtree (via `src/core/minions/spawn-helpers.ts`); Layer 3 is the container's own tini for hard Bun crashes. - `src/core/minions/` — Minions job queue: BullMQ-inspired, Postgres-native (queue, worker, backoff, types, protected-names, quiet-hours, stagger, handlers/shell). - `src/core/minions/queue.ts` — MinionQueue class (submit, claim, complete, fail, stall detection, parent-child, depth/child-cap, per-job timeouts, cascade-kill, attachments, idempotency keys, child_done inbox, removeOnComplete/Fail). `add()` takes a 4th `trusted` arg (separate from `opts` to prevent spread leakage); protected names in `PROTECTED_JOB_NAMES` require `{allowProtectedSubmit: true}` and the check runs trim-normalized (whitespace-bypass safe). v0.14.1 #219: `add()` plumbs `max_stalled` through with a `[1, 100]` clamp; omitted values let the schema DEFAULT (5) kick in. v0.19.0: `handleWallClockTimeouts(lockDurationMs)` is Layer 3 kill shot for jobs where `FOR UPDATE SKIP LOCKED` stall detection and the timeout sweep both fail to evict (wedged worker holding a row lock via a pending transaction). v0.19.1: `maxWaiting` coalesce path now uses `pg_advisory_xact_lock` keyed on `(name, queue)` to serialize concurrent submits for the same key, and filters on `queue` in addition to `name` so cross-queue same-name jobs don't suppress each other.

The post-await deadline check at brain-writer.ts:512 uses Date.now() >= deadline; on that tick the check evaluated false and scanOneSource ran src-a anyway. Test then asserted firstSource.status === 'skipped' and got 'scanned'. Fix: add 1ms overshoot to the race-timer schedule: setTimeout(..., remainingMs + 1) Guarantees the timer fires past the deadline by at least one millisecond regardless of runner timer drift. Cost: 1ms additional wall-clock latency on hung COUNT queries — operationally negligible. Verified: stress-tested 5/5 passing locally. The bug class is identical to the one the existing test comment block (lines 180-187) documents (`>=` not `>` at line 512); this +1ms is the belt to that suspenders.
