v0.40.9.0 feat(chunker): .sql indexing via tree-sitter + code-def on SQL DDL (#1173) by garrytan · Pull Request #1350 · garrytan/gbrain

Summary

Closes .sql files not indexed by gbrain sync walker #1173. gbrain sync now indexes .sql files; gbrain code-def <name> returns the CREATE TABLE / FUNCTION / VIEW / INDEX / PROCEDURE / TYPE / SCHEMA / DATABASE / TRIGGER site.
Vendors DerekStride/tree-sitter-sql @ c2e1e08db1ea20dc23bdb8d228a81a8756e9c450, built with tree-sitter-cli@v0.26.3 --abi 14 (matches web-tree-sitter@0.22.6).
extractSymbolName gains an inline SQL branch (extractSqlSymbolName) that dives through DerekStride's statement wrapper into the inner DDL child and extracts the target identifier. DML kinds (select/insert/update/delete/merge/with) return null so chunks emit unnamed — code-def is a definition signal.
normalizeSymbolType gains parallel SQL branches: create_table → 'table', create_view → 'view', etc.
src/commands/code-def.ts:DEF_TYPES allowlist extended with 'table' | 'view' | 'index' | 'procedure' | 'schema' | 'database' | 'trigger'. Without this, chunks landed correctly but were invisible to code-def.

Honesty note on binary size

The DerekStride grammar covers PostgreSQL, MySQL, SQLite, and T-SQL basics in one parser. That breadth comes from a 40 MB generated parser.c compiling to an 11 MB WASM — substantially larger than the plan's 400 KB-1.4 MB estimate. The compiled gbrain binary grows ~6%. If that matters in your deployment, file an issue and we'll evaluate a narrower-coverage fork as a follow-up.

/plan-eng-review decisions

6 decisions (D1-D6) captured during review, including the D6 scope correction driven by codex outside voice's F2 finding ("SQL chunking ≠ working code-def without symbol extraction"). JSDoc / doc_comment extraction was originally bundled in this wave but pivoted to a dedicated follow-up after codex argued doc_comment activation is a separate product decision (involves ~$10-50/brain reembed cost) not a hitchhiker on a language-add. Full rationale + decisions in CHANGELOG.md.

Test plan

bun test test/chunkers/code.test.ts — 24 pass (8 new SQL cases)
bun test test/sync-classifier-widening.test.ts — 21 pass (1 new SQL case)
bun test test/e2e/code-indexing.test.ts — 18 pass (7 new SQL E2E cases including the load-bearing canary: findCodeDef returns CREATE TABLE site)
bun test test/build-llms.test.ts — 7 pass (verifies regenerated llms.txt is fresh)
bun run verify — typecheck + all 11 shell pre-checks green
Manual end-to-end: gbrain sync a fixture .sql file → gbrain code-def <table_name> returns the chunk
Full unit-test sweep: 3 pre-existing master-flake failures (long-running tests timing out under 8-shard concurrency: check-system-of-record.sh, eval-longmemeval.test.ts:JSONL format guard, eval-longmemeval.test.ts:--by-type emits a final summary). All pass in isolation — not regressions from this branch.

…n tool Vendored from DerekStride/tree-sitter-sql @ c2e1e08db1ea20dc23bdb8d228a81a8756e9c450, built with tree-sitter-cli@v0.26.3 + --abi 14 (matches web-tree-sitter 0.22.6's ABI 13-14 range; default --abi 15 was incompatible). 11 MB binary — substantially larger than the plan's 400KB-1.4MB estimate (DerekStride's multi-dialect grammar generates 40MB of parser.c). tools/inspect-sql-grammar.ts is a one-shot Step 0 script that parsed 9 representative SQL fixtures and surfaced three load-bearing facts: 1. Top-level node type is `program > statement > <kind>`. Every top-level node is `statement`, with the actual statement type as its single named child. TOP_LEVEL_TYPES['sql'] = new Set(['statement']) catch-all. 2. The generic extractSymbolName returns null for EVERY SQL node — needs a SQL-specific branch that dives into statement.namedChild(0). 3. DML emits one statement-chunk per statement (NOT one fat recursive- fallback chunk). $$ body parses cleanly. Even invalid SQL ("SELECT FROM WHERE") still produces a select-shaped statement, not a parse error.

Five additive edits to src/core/chunkers/code.ts: 1. Import G_SQL grammar (DerekStride SHA in inline comment). 2. Extend SupportedCodeLanguage union with 'sql'. 3. Register sql entry in LANGUAGE_MANIFEST. 4. Add .sql case to detectCodeLanguage. 5. TOP_LEVEL_TYPES['sql'] = Set(['statement']) catch-all per Step 0 finding that DerekStride wraps every top-level node in `statement`. Two SQL-aware additions to existing helpers: - extractSymbolName: dives into `statement.namedChild(0)` and routes to extractSqlSymbolName. DDL kinds (create_table/function/view/index/ procedure/type/schema/database/trigger + alter_table/view) extract target identifier via `name` field with fallback to identifier-shaped children. DML kinds (select/insert/update/delete/merge/with) return null so chunks emit unnamed. - normalizeSymbolType: adds 'table', 'view', 'index', 'procedure', 'type', 'schema', 'database', 'trigger' branches so chunk headers say "table users" instead of "statement users". - emit-path passes inner-child type to normalizeSymbolType when the outer node is `statement` (SQL only condition). sync.ts: add '.sql' to CODE_EXTENSIONS so isCodeFilePath routes it to importCodeFile with page_kind='code'. Manual verification (bun /tmp/test-sql-chunker2.ts) confirms CREATE TABLE, CREATE FUNCTION (with $$ body), CREATE INDEX all produce chunks with correct symbolName + symbolType. Small-sibling merging collapses short-statement runs into single merged chunks (existing behavior, not SQL-specific).

Unit tests (test/chunkers/code.test.ts, 8 new cases): - detectCodeLanguage now covers all 30 extensions (.sql added) - is-case-insensitive extended to .SQL - CREATE TABLE / FUNCTION / INDEX / VIEW / ALTER TABLE each extract target name into symbolName + map to correct symbolType - CREATE FUNCTION with $$ body parses without crashing - DML statements (INSERT) emit chunks but with symbolName=null - Mixed DDL+DML: per-statement emission, only DDL gets symbolName - Header includes "[SQL]" language tag - Invalid SQL ("SELECT FROM WHERE") doesn't crash the parser Sync classifier (test/sync-classifier-widening.test.ts, 1 new case): - isCodeFilePath('migrations/001_init.sql') true, case-insensitive E2E (test/e2e/code-indexing.test.ts, 7 new cases): - SQL import produces pages.type='code' + page_kind='code' - CREATE TABLE / FUNCTION chunks have correct symbol_name + symbol_type - findCodeDef returns CREATE TABLE / FUNCTION / INDEX / VIEW sites by name (load-bearing D2 canary — proves SQL is code intelligence, not just searchable text) - beforeAll timeout bumped to 30s (92-migration replay + 11MB SQL grammar load pushes past default 5s) Source change to make E2E pass (src/commands/code-def.ts): - DEF_TYPES extended with 'table', 'view', 'index', 'procedure', 'schema', 'database', 'trigger'. The chunker's normalizeSymbolType already maps create_table → 'table' etc; without this allowlist extension the chunks were indexed correctly but invisible to `gbrain code-def <name>`.

…rename + budget bumps Four flakes surfaced during the v0.40.9.0 full unit sweep. All pass in isolation; all fail under 8-shard parallel CPU contention. Fixes below hit the actual root cause, not symptoms — no quarantine-and-ignore. ────────────────────────────────────────────────────────────────────── 1. check-system-of-record.sh — "catches violations in scripts/ alongside src/" ────────────────────────────────────────────────────────────────────── Root cause: under shard load, the test's `spawnSync('git', ['init', '-q'])` in /tmp/gate-test-* occasionally silently fails (filesystem contention), so the fakeRepo has no .git dir. The gate then runs `git rev-parse --show-toplevel` which walks UP past the fakeRepo into our real gbrain repo, sets ROOT=/real/gbrain/repo, scans the clean real src/+scripts/, exits 0. The test "expects exit 1 + 'naughty.ts' in stdout" sees exit 0 and empty stdout — fails. Fix: - scripts/check-system-of-record.sh: honor `GBRAIN_SCAN_ROOT` env var BEFORE the git-rev-parse fallback. Pure additive — production callers unchanged, tests get deterministic resolution. - test/check-system-of-record.test.ts: `runGate` sets `GBRAIN_SCAN_ROOT: cwd` in spawnSync env. Closes the flake at the cause, not at the symptom (a retry loop would have papered over the real bug — the gate's resolution was too clever for its own good). ────────────────────────────────────────────────────────────────────── 2-4. eval-longmemeval.test.ts — 3 timeouts under 8-shard parallel ────────────────────────────────────────────────────────────────────── Root cause: the file takes ~50s in isolation (full LongMemEval harness replay with stubbed LLM). Under 8-shard parallel, CPU contention pushes individual tests past bun's default 60s timeout. 3 tests timed out: - JSONL format guard (60s timeout) - JSONL key contract (65s timeout) - --by-type emits final by_type_summary (60s timeout) Fix: rename `test/eval-longmemeval.test.ts` → `.slow.test.ts`. This is exactly what the .slow taxonomy exists for per CLAUDE.md: > "*.slow.test.ts → intentional cold-path tests; would dominate the > fast loop's wallclock" Verified routing: - Local `bun run test`: skips longmemeval (no flake) - Local `bun run test:slow`: runs explicitly, 31 pass in 277s - CI `scripts/test-shard.sh`: still runs (.slow NOT excluded from FNV bucketing — verified by dry-run: lands in shard 3/4) ────────────────────────────────────────────────────────────────────── Adjacent fix: slow wrapper + test-shard.slow.test.ts beforeAll budget ────────────────────────────────────────────────────────────────────── The longmemeval move surfaced a 4th flake: `test-shard.slow.test.ts`'s beforeAll shells out 4×`scripts/test-shard.sh --dry-run-list` (~4s solo each); when longmemeval is now running in the same slow-wrapper invocation hogging CPU, the 4 sequential dry-runs slip past the 60s beforeAll timeout. Fixes: - scripts/run-slow-tests.sh: bump bun test --timeout 60s → 120s. Slow tests are explicit by-name; a generous per-test budget is correct posture, not a workaround. - test/scripts/test-shard.slow.test.ts: bump beforeAll budget 60s → 180s. Matches the actual workload under parallel slow-shard execution. ────────────────────────────────────────────────────────────────────── Verification ────────────────────────────────────────────────────────────────────── - `bun test test/check-system-of-record.test.ts` — 6 pass (in isolation) - `bun run test:slow` — 31 pass in 277s (was: 1 fail at 89s before fixes) - Full `bun run test` re-run in progress; will confirm 0 fail.

…shard cap 600→900 Round 1 caught 4 named flakes; the post-fix sweep surfaced 2 more from the same flake class (calibration values that were correct when set but are no longer correct for the larger test suite). 5. longmemeval-trajectory-routing — "perf gate preserved" (3rd-party flake) Failure: under shard load, test asserts elapsed<10s but real wallclock was 37s. The gate is supposed to catch real harness-layer regressions, not raw cycle counts; 8-shard CPU contention routinely 3-5x's wallclock. Fix: mode-aware ceiling. Solo run keeps the tight 10s gate (catches real algorithmic regressions). Shard run (detected via `$SHARD` env set by the parallel wrapper) loosens to 60s — still catches >6x regressions but tolerates parallel contention. Per-test timeout bumped 5s default → 90s. 6. Per-shard wedge-detection too tight (false WEDGED markers) Shards 5+6 of the prior sweep both got WEDGED markers at the 600s wrapper cap, but their bun-internal timer shows they actually finished in 620-770s with 0 failures. The 600s shard cap was calibrated when shards held ~600 tests; suite growth through v0.40.x pushed individual shards to 1100+ tests and 620-770s legitimate wallclock. Fix: bump GBRAIN_TEST_SHARD_TIMEOUT default 600→900. Real hangs still hit the 900s cap; fully-completed shards no longer false-kill at 600s. Env override preserved. ────────────────────────────────────────────────────────────────────── Cumulative flake hardening (across 2 commits) ────────────────────────────────────────────────────────────────────── 1. check-system-of-record gate — GBRAIN_SCAN_ROOT env override 2. eval-longmemeval (3 tests) — rename to .slow 3. run-slow-tests.sh — bump --timeout 60s → 120s 4. test-shard.slow.test.ts — bump beforeAll 60s → 180s 5. longmemeval perf gate — shard-mode-aware ceiling 10s/60s 6. Per-shard wedge cap — bump 600s → 900s All root-cause fixes; zero retry-loop / quarantine-and-ignore. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…ntion SIGKILLs Sweep #3 (after the prior 6 hardening fixes + master merge) caught a new flake class: shard 5 got SIGKILL'd (rc=137) during source-health.test.ts's 92-migration PGLite replay. 8 parallel shards each running their own PGLite WASM init + 92-migration replay contend severely on shared FS state — even with the 900s shard cap, shard 5 wedged so hard the wrapper fell back to SIGKILL. Root cause: 8-shard parallel was aggressive (we picked detect_cpus on a 12-perf-core M-series, clamped to 8). CI runs 4 via test-shard.sh and is stable. 8 → 4 trades ~2x local wallclock for reliability + matches CI fan-out exactly. Override still available via --shards N or SHARDS=N (clamped at 8 ceiling). Side benefit: also resolves the 2 .serial.test.ts spawn failures in sweep #3 — those serial tests run AFTER the parallel pass, so when the parallel pass leaks PGLite write-locks under heavy contention, the serial spawn tests inherit the polluted state and timeout on their own subprocess spawns. Reducing parallel contention upstream cleans up the FS state by the time serial runs. ────────────────────────────────────────────────────────────────────── Cumulative flake hardening (3 commits, 7 fixes) ────────────────────────────────────────────────────────────────────── 1. check-system-of-record gate — GBRAIN_SCAN_ROOT env override 2. eval-longmemeval (3 tests) — rename to .slow 3. run-slow-tests.sh — bump --timeout 60s → 120s 4. test-shard.slow.test.ts — bump beforeAll 60s → 180s 5. longmemeval perf gate — shard-mode-aware ceiling 10s/60s 6.

Sweep #4 at the new 4-shard default ran cleanly: 0 failures, 10072 pass. BUT shard 1 was false-killed at 900s even though its internal completion was 968s (the same flake pattern as the prior 600→900 bump, just at the new shard sizing). Reason: 8→4 shard reduction means each shard now runs 2x more files (159 vs 80) and 2x more tests (~2420 vs ~1100). Internal wallclock per shard climbed from 620-770s (8-shard) to 960-1020s (4-shard). The 900s cap was sized for the prior 8-shard sizing; 4-shard sizing needs more headroom. 1500s gives ~55% headroom over observed 4-shard wallclock and catches real hangs that wouldn't complete in 1500s anyway. ────────────────────────────────────────────────────────────────────── Cumulative flake hardening (4 commits, 8 fixes) ────────────────────────────────────────────────────────────────────── 1. check-system-of-record gate — GBRAIN_SCAN_ROOT env override 2. eval-longmemeval (3 tests) — rename to .slow 3. run-slow-tests.sh — bump --timeout 60s → 120s 4. test-shard.slow.test.ts — bump beforeAll 60s → 180s 5. longmemeval perf gate — shard-mode-aware ceiling 10s/60s 6.

Flake-hardening wave — full unit sweep now 10,072 / 0 / 0

The original v0.40.9.0 ship had 3 pre-existing master flakes in the test plan. User pushed back: "fix these flakes with hardening / smarter concurrency." Did that. Sweep is now fully green.

Final result

shard 1/4: pass=2420 fail=0 skip=0 rc=0
shard 2/4: pass=2263 fail=0 skip=0 rc=0
shard 3/4: pass=2622 fail=0 skip=0 rc=0
shard 4/4: pass=2342 fail=0 skip=0 rc=0
serial:    pass=425  fail=0          rc=0
[unit-parallel] elapsed=903s | pass=10072 fail=0 skip=0

Eight root-cause fixes (no quarantine-and-ignore)

#	Fix	Root cause
1	`check-system-of-record.sh` — honor `GBRAIN_SCAN_ROOT` env override	Under shard load the test's `git init -q` in `/tmp/gate-test-*` occasionally silently failed; the gate's `git rev-parse --show-toplevel` then walked UP past the fakeRepo into our real gbrain repo, scanned the clean src+scripts, exited 0 → "expects exit 1" failed. Env override pins the scan dir explicitly.
2	`eval-longmemeval.test.ts` → `.slow.test.ts` rename	File takes ~50s in isolation; under 8-shard parallel CPU contention 3 tests hit bun's 60s timeout. `.slow` taxonomy exists exactly for this — skipped from local fast loop, still runs in CI's test-shard.sh (FNV bucketing includes `.slow`) and via `bun run test:slow`.
3	`run-slow-tests.sh` — bump `--timeout` 60s → 120s	Slow tests legitimately approach 60s in isolation; need parallel-load headroom.
4	`test-shard.slow.test.ts` — bump `beforeAll` 60s → 180s	4 sequential `gtimeout shard-shell-out` × ~4s solo each = ~16s; under slow-shard concurrency with longmemeval co-running, the 4-shell-out routine slipped past 60s.
5	`longmemeval-trajectory-routing` perf gate — shard-mode-aware ceiling	Test asserted `elapsed<10s`; under 8-shard CPU contention real wallclock was 37s. New ceiling: 10s solo (catches real algorithmic regressions), 60s under `$SHARD` env (tolerates parallel contention).
6	Per-shard wedge cap — `GBRAIN_TEST_SHARD_TIMEOUT` 600 → 1500	The 600s cap was sized when shards held ~600 tests; at 8-shard each shard now ran 1100+ tests / 620-770s legit wallclock. 8→4-shard reduction (#7) pushed per-shard to ~2400 tests / 960-1020s legit wallclock. 1500s gives ~55% headroom over observed.
7	Default local shards — clamp 8 → 4	The shard-5 SIGKILL class in sweep #3 was 8 parallel PGLite WASM inits contending on `source-health.test.ts`'s 92-migration replay — even 900s wasn't enough. CI uses 4 via test-shard.sh and is stable. 8 → 4 trades ~2x local wallclock for reliability + parity with CI fan-out. Override still available via `--shards N` or `SHARDS=N` (clamped at 8 ceiling).
8	(same file as #6) Cap recalibration for new shard sizing	After #7 dropped from 8 → 4 shards, each shard's wallclock climbed from 770s → 968s. The 900s cap I set with the prior calibration false-killed shard 1 at 900s even though it completed at 968s. Bumped to 1500s as the final calibrated value.

Commits

9819afc1 — round 1: 4 root causes (gate env, longmemeval rename, slow wrapper timeout, beforeAll budget)
aaa60ef7 — round 2: 2 more (shard-aware perf gate, shard cap 600→900)
e636dadd — round 3: 1 more (shards 8→4, kills the SIGKILL class)
08f22949 — round 4: 1 more (shard cap 900→1500, calibrated for new shard sizing)

…ze-skip-embed (#1351) * feat: add content-sanity assessor + embed-skip helper + audit JSONL primitives 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.

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: lint rules + doctor checks + 'gbrain sources audit' CLI Three operator surfaces backed by the shared content-sanity assessor: lint.ts (2 new rules): - huge-page: bytes (compiled_truth + timeline post-parse) exceeds warn or block threshold. 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 <id> [--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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.40.9.0) v0.40.9.0 — content sanity defense: junk-pattern throw + oversize-skip-embed. Plus TODOS.md entries for the 9 deferred v0.41+ follow-ups: - chunk-level embed-quarantine (Codex r1 #3 — page-level granularity wrong) - source-repo remediation CLI (gbrain sources prune-junk) - threshold validation post-deploy on real corpora - brain-score no_junk_pages_score component - pages soft-delete --where CLI (paired with prune-junk) - post-v0.45 operator-regex extensibility (needs real ReDoS story) - post-v0.45 HTML-density rule (needs fenced-code handling) - bytes-parity E2E across lint + doctor - 5-path narrow-waist E2E pin tests + doctor integration tests Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: update CLAUDE.md for v0.40.9.0 content-sanity wave Add v0.40.9.0 Key Files entries for the content-sanity defense modules: content-sanity.ts (assessor), content-sanity-literals.ts (operator loader), embed-skip.ts (5-site shared predicate), audit/content-sanity-audit.ts (JSONL writer). Extend doctor.ts, lint.ts, embed.ts, import-file.ts, and sources.ts entries with the v0.40.9.0 surfaces (3 new doctor checks, 2 new lint rules, embed-skip filter at 5 sites, importFromContent gate, sources audit subcommand). Regenerate llms-full.txt per the CLAUDE.md edit rule. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: rebump v0.40.9.0 → v0.40.10.0 (queue collision with #1350) PR #1350 also claimed v0.40.9.0. Advancing this PR to v0.40.10.0 so CI's version-gate doesn't reject on overlap. No functional change — same shipped content, just a different version slot. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(brain-writer): +1ms overshoot on COUNT-race timer to defeat CI boundary flake PR #1351 ship CI hit a single test failure (one in 2552): (fail) scanBrainSources partial-scan state > hanging COUNT does not exceed deadline — Promise.race timeout fires [579.01ms] Run: https://github.com/garrytan/gbrain/actions/runs/77611667786 Cause: heavily-loaded CI runners (8 parallel shards × 4 concurrent test files = ~32 concurrent bun processes) occasionally let the setTimeout race callback resolve a microsecond BEFORE the wall-clock boundary, leaving Date.now() one tick below deadline. 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.
