From dfa15ba22b3f099a16d055a3a14ef0de2228b99c Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Mon, 25 May 2026 14:56:38 -0700 Subject: [PATCH] v0.41.10.0 feat: orphan reduction via --by-mention + UTF-16 surrogate-pair fix (#1442) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(synthesize): UTF-16 surrogate-safe hard-split in chunker Part A of v0.42.0.0 fix wave: lifts surrogate-pair-safe slicing from src/core/eval-contradictions/judge.ts into a new shared module src/core/text-safe.ts. The dream-cycle chunker findBoundary tier-3 fallback (synthesize.ts) previously hard-split at maxChars, orphaning a high surrogate when the boundary landed inside emoji / non-BMP CJK / mathematical alphanumerics. Resulting chunks were not byte-identical to the source content, which broke the v0.30.2 D9 stable-chunk-identity invariant — the per-chunk idempotency key drifted across retries on transcripts containing 4-byte UTF-8 characters near a hard-split. Five agent-authored PRs (#1378-#1382) each independently introduced a narrow safeSliceEnd helper that handled ONE of the three correctness cases (high+low pair straddle) but missed the AT-low-surrogate case that fires when a boundary lands inside a complete pair. The shared text-safe.ts module exports both truncateUtf8 (the verbatim sliced string, for judge.ts) and safeSplitIndex (the boundary index, for chunker hot path), each covering all three cases. Co-authored credit: @garrytan-agents for surfacing the fix in PRs #1378-#1382 (closed in favor of consolidated design doc #1409). * New: src/core/text-safe.ts (truncateUtf8 + safeSplitIndex helpers). * New: test/text-safe.test.ts (18 cases, all 3 surrogate cases plus boundary-after-pair conservative back-up per codex CK16). * refactor(judge): import truncateUtf8 from text-safe; re-export for back-compat. Existing 32 judge tests pass unchanged. * fix(synthesize): findBoundary tier-3 routes through safeSplitIndex. 3 new surrogate-safety cases in test/cycle-synthesize-chunker.test.ts (emoji at boundary, non-BMP CJK at boundary, determinism + joined chunks reconstruct source byte-identical across 5 fuzzed hashes). Co-Authored-By: Claude Opus 4.7 (1M context) * feat(schema): widen link_source CHECK to include 'mentions' (v95) Part B of v0.42.0.0: link_source enum widening to admit a fourth provenance channel for auto-linked body-text mentions from the upcoming `gbrain extract links --by-mention` command. Codex outside-voice review on the v0.42.0.0 plan caught that the existing link_source CHECK is a hard wall (src/schema.sql:356) — my earlier draft claimed "no schema migration needed; link_source is free-form TEXT." Wrong. The CHECK admits only NULL OR ('markdown', 'frontmatter', 'manual'); attempting to insert link_source='mentions' would have raised a constraint violation on every auto-link write. Migration v95 widens the CHECK to admit 'mentions' alongside the three existing values. Mentions are intentionally a separate provenance from markdown (human-authored links) so the backlink-count SQL in postgres-engine + pglite-engine can filter `WHERE link_source != 'mentions'` for search ranking (D12). Mentions still count toward orphan-ratio and graph traversal — distinct semantics from the three human-authored sources, modeled cleanly on the dedicated CHECK value. * src/schema.sql: widened CHECK with provenance comment. * src/core/pglite-schema.ts: same widening (PGLite engine parity). * src/core/schema-embedded.ts: regenerated via `bun run build:schema`. * src/core/migrate.ts: new migration v95 `links_link_source_check_includes_mentions` with both Postgres and PGLite branches. DROP IF EXISTS + ADD CONSTRAINT pattern so re-applying the migration is a no-op (idempotent). * test/schema-migrate-link-source-mentions.test.ts (NEW, 7 cases): registration shape, SQL shape (all 4 values present + DROP IF EXISTS pattern), PGLite branch present, post-migration insert succeeds, CHECK still rejects unknown values (widening did not nullify the gate), idempotent re-application via runMigration. Co-Authored-By: Claude Opus 4.7 (1M context) * refactor(orphans): expose getOrphansData alias as canonical pure data fn (D1) D1 from /plan-eng-review for v0.42.0.0: doctor's upcoming orphan_ratio check needs the SAME exclusion logic as `gbrain orphans` so the two surfaces cannot disagree on what counts as an orphan. The existing findOrphans() was already the pure data fn — this commit just makes that contract explicit via the getOrphansData alias and pins it with an IRON RULE regression test. * src/commands/orphans.ts: export const getOrphansData = findOrphans (alias, same function reference). Documents the v0.42.0.0 contract in findOrphans' docstring. * test/orphans-pure-fn.test.ts (NEW, 12 cases): - getOrphansData === findOrphans (same reference). - findOrphans + getOrphansData deep-equal output. - includePseudo branch toggles excluded count. - CLI --json output deep-equals findOrphans (IRON RULE — catches drift if anyone adds CLI-side post-filtering). - CLI --count matches total_orphans (with and without --include-pseudo). - shouldExclude regression: pseudo-pages, auto-suffix, raw segment, deny-prefixes, first-segment exclusions all fire correctly; regular slugs are NOT excluded. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(engine): filter mentions out of backlink-count for search ranking (D12) D12 from /plan-eng-review for v0.42.0.0: codex outside-voice review caught that engine.getBacklinkCounts had NO link_source filter — so every link counted equally toward backlink-boost in hybridSearch. Running `gbrain extract links --by-mention` (migration #1 of #1409) would silently shift search ranking globally on first run, boosting popular-mention pages over intentional-backlink pages. Add `AND l.link_source IS DISTINCT FROM 'mentions'` to the LEFT JOIN in both engines. `IS DISTINCT FROM` is NULL-safe per the [sql-neq-misses-null-drift] memory: a naive `!= 'mentions'` would silently drop legacy pre-v0.13 rows where link_source IS NULL (because NULL != 'mentions' evaluates to NULL not TRUE in SQL three-valued logic). The IS DISTINCT FROM form treats NULL as a distinct value so legacy rows still count toward backlinks — the only rows filtered are the explicitly mention-derived ones from v0.42.0.0+. Mentions still count toward: - orphan-ratio (the whole point — `findOrphans` runs against `links` with no source filter, so an auto-linked page is no longer an orphan) - graph traversal (`traverseGraph` walks all link_source values) - graph adjacency (`getAdjacencyBoosts` includes mentions in the induced subgraph counts) Mentions are filtered ONLY from: - `getBacklinkCounts` (this commit) — the input to hybridSearch's backlink_boost stage * src/core/postgres-engine.ts: AND clause on the LEFT JOIN. * src/core/pglite-engine.ts: same change for engine parity. * test/backlink-count-mention-filter.test.ts (NEW, 6 cases): - 10 markdown + 0 mention → count = 10 - 0 markdown + 50 mention → count = 0 - 10 markdown + 50 mention → count = 10 - NULL link_source legacy rows still count (IS DISTINCT FROM semantics) - mixed (markdown + frontmatter + manual + mentions) → only mentions filtered - uninitialized slug returns 0 Co-Authored-By: Claude Opus 4.7 (1M context) * feat(by-mention): pure mention scanner with gazetteer + guards (D2/D6/D12/D13) Net new module powering migration #1 of #1409 (orphan reduction). buildGazetteer queries entity-typed pages (hardcoded D2 filter: person/company/organization/entity, pack-aware deferred to TODO-1) and produces a token-Map lookup keyed by lowercase first-token. findMentionedEntities is a pure function that scans body text against the gazetteer, applies maximal-munch matching (longest entry wins at each offset), self-link guard (D13), cross-source guard, and per-page first-mention-only cap (1 link per source→target pair regardless of how many body mentions). Token-Map + multi-word phrase pass per D6 — no new deps, no regex alternation (pathological perf at 5K patterns), no Aho-Corasick (dep tax not justified at this scale). At each token offset, lookup in Map is O(1); multi-word entries validate subsequent tokens. Bucket pre-sorted longest-first so the first valid entry IS the maximal-munch winner. Ignore-list semantics per CK12: built-in ambiguous tokens (Apple, Amazon, Square, Stripe, Box, Meta, Target, Oracle) suppressed at gazetteer-build time ONLY when no corresponding entity page exists. If the user has explicitly created companies/apple, gazetteer presence wins — ignore list does NOT override user intent. Min-name-length filter at 4 chars kills false-positive 2-3-char names (AI, YC, X, IBM). Codex CK13 noted this trade-off will under-deliver on 3-char real entities; pack-aware follow-up (TODO-1) can let users opt 3-char entity types in deliberately. Code-block stripping via existing stripCodeBlocks() from link-extraction.ts. CK8 fix: stripCodeBlocks was internal-only; this commit exports it so by-mention.ts can reuse without rolling its own fenced/inline code parser. * src/core/by-mention.ts (NEW, 240 LOC): - LINKABLE_ENTITY_TYPES const (hardcoded D2 type filter). - GazetteerEntry + Gazetteer + Mention types. - buildGazetteer(engine, opts) — engine-backed, hardcoded type filter, ignore-list at build time per CK12, sort buckets longest-first. - findMentionedEntities(text, gazetteer, opts) — pure, maximal-munch, guards (self-link/cross-source/first-mention-cap), code-block strip. * src/core/link-extraction.ts: export stripCodeBlocks (CK8 fix). * test/by-mention.test.ts (NEW, 22 cases): - All 20 plan-mandated cases. - Plus extraIgnore user-override case + LINKABLE_ENTITY_TYPES contract pin. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(extract): --by-mention auto-link entity mentions (migration #1 of #1409) Wires the v0.42.0.0 mention scanner into 'gbrain extract links'. Mode dispatch: when --by-mention is set, runs ONLY the new mention pass (skips default link/frontmatter extract) so the two surfaces don't conflict mid-run. The default extract path is unchanged. Flag plumbing: * --by-mention: opts into the mention pass. Mode dispatch. * --source fs --by-mention rejected with paste-ready --source db fix-hint (D7: gazetteer needs the engine; FS-walk + DB-gazetteer is incoherent). * timeline --by-mention rejected (mentions are a links-pass concern). * --source-id scopes the page WALK; gazetteer remains brain-wide (cross-source guard in findMentionedEntities suppresses scanning pages in source A from auto-linking entities in source B). * --since DATE filters the walk to recently-modified pages. * --type filter applies (rarely useful; included for parity). * --dry-run prints add_link action lines without writing; --json emits one JSON line per dry-run action. extractMentionsFromDb function: * buildGazetteer once per run via hardcoded type filter (D2). * Walks pages via engine.listAllPageRefs (DB-source only). * Reads body as compiled_truth || '\n\n' || COALESCE(timeline, '') per D3 — separator-joined so an end-of-compiled token doesn't merge with a start-of-timeline token into a false phrase match. * findMentionedEntities returns Mention[] with self-link guard (D13) + cross-source guard + first-mention-only cap baked in. * addLinksBatch with link_source='mentions' — distinct provenance channel that backlink-count filters out for search ranking (D12). * Empty-gazetteer no-op with informative message (no entity pages = nothing to scan). * src/commands/extract.ts: --by-mention flag + mode dispatch + FS rejection + extractMentionsFromDb function (~120 LOC). * test/extract-by-mention.test.ts (NEW, 12 cases): end-to-end happy path, idempotency, --dry-run no writes, --json output shape, --source-id scoping, --source fs rejection with fix-hint, timeline rejection, mode dispatch (no markdown rows when --by-mention), coexistence of markdown + mention link_source on same (from,to) pair via ON CONFLICT key, schema migration verification (link_source='mentions' insert succeeds), empty-brain no-op, cross-source guard (team-b post → default acme = no link). Co-Authored-By: Claude Opus 4.7 (1M context) * feat(doctor): orphan_ratio check on local + thin-client surfaces (D5/D11) D5/D11 from /plan-eng-review for v0.42.0.0: surface orphan-page count in 'gbrain doctor' so users discover the new --by-mention fix without having to know the feature exists. Two surfaces because thin-client installs (gbrain init --mcp-only) route to runRemoteDoctor entirely — adding the check to runDoctor only would miss every brain-server consumer (codex CK5 caught this exactly during outside-voice review). Local surface (src/commands/doctor.ts): * Inserts as check '9b' right after graph_coverage. * Consumes getOrphansData() — the canonical pure data fn from T5 — so doctor and 'gbrain orphans --count' cannot disagree on the ratio. * Vacuous gate at < 100 entity pages (small brains naturally show high orphan ratio; not actionable signal). * warn > 0.5, fail > 0.8; both states recommend 'gbrain extract links --by-mention' as the fix. Thin-client surface (src/core/doctor-remote.ts): * New exported runOrphanRatioCheck function. Mirrors local logic but routes through find_orphans MCP op (existing v0.12.3 op, scope: read — even minimal-scope thin-clients can call it). * Operator-pointing hint: 'Ask the brain operator at to run gbrain extract links --by-mention'. Thin-client users can't run the fix against a brain they don't host (v0.31.1 bug class). * Network failure fall-back: returns informational ok with network_error detail, NOT fail — earlier mcp_smoke catches genuine unreachable; orphan_ratio is informational only. * Skippable via the existing skipScopeProbe flag so hermetic fixtures that don't implement find_orphans on /mcp don't hang. Wiring in --by-mention extract.ts integration test (fix-up): CliOptions field is `progressInterval` not `progressIntervalMs`, and `timeoutMs: null` is required. Pre-existing tsc error surfaced when typechecking the new doctor changes. * test/doctor-orphan-ratio.test.ts (NEW, 10 cases): - <100 entity pages → vacuous ok - 100+ entities + low ratio (20%) → ok - high ratio (70%) → warn with fix-hint - very high ratio (90%) → fail with urgency fix-hint - zero entity pages → vacuous ok - JSON envelope contains orphan_ratio check - Thin-client: network failure → informational ok with detail - Cross-surface parity: source greps verify orphan_ratio name and fix command appear in BOTH doctor.ts and doctor-remote.ts; local hint is self-fix, thin-client hint asks the operator. Co-Authored-By: Claude Opus 4.7 (1M context) * test(e2e): orphan-reduction end-to-end with cross-surface count parity Pins the v0.42.0.0 design-doc claim shape — "material reduction in orphan pages via --by-mention" — without committing to a specific % (per TODO-4=C decision to soften the 88%->_30% promise into a "material reduction, exact figure TBD via post-merge measurement on representative brain"). 3 e2e cases via hermetic PGLite: * Seed 20 entities + 5 content pages mentioning 15 → assert orphan count drops by >=10 after --by-mention (material delta). * Cross-check the D1 single-source contract end-to-end: gbrain orphans --count, getOrphansData() pure fn, and the doctor JSON orphan_ratio message all reflect the same numerator. If a future change makes them disagree, this fires. * Re-run idempotency: second --by-mention invocation produces 0 new mention rows AND the first run actually created some (sanity gate so a no-op pass doesn't trivially satisfy the idempotency test). * test/e2e/orphan-reduction.test.ts (NEW, 3 cases, hermetic PGLite, no DATABASE_URL needed). Co-Authored-By: Claude Opus 4.7 (1M context) * release: v0.41.10.0 — orphan reduction via --by-mention + surrogate-pair fix Bumps VERSION + package.json to 0.41.10.0 (next available slot in the v0.41.x queue after master moved to v0.41.4.0). Minor bump scope: new CLI flag (`gbrain extract links --by-mention`), new schema migration v95, new doctor check `orphan_ratio`, new public src/core/text-safe.ts module, new src/core/by-mention.ts module, new link_source enum value with ranking-filter semantic. CHANGELOG entry follows the v0.41.x voice rules: ELI10 lead, To take advantage block with paste-ready commands, How to turn it on, What you'd see, Promise calibration (softens design-doc 88%->_30% claim per codex CK13), What to watch for, Itemized changes split into Part A (surrogate-pair fix) + Part B (auto-link --by-mention) + Follow-ups (TODO-1 through TODO-4). Credits @garrytan-agents for the underlying PR work (#1378-#1382 closed in favor of design doc #1409). TODOS.md gets four new follow-up entries (pack-aware gazetteer, cycle integration, MCP op, post-merge measurement). System-of-record annotation: the addLinksBatch call in extractMentionsFromDb carries `gbrain-allow-direct-insert` per the canonical reconcile-layer write pattern. 3-line audit: VERSION + package.json + CHANGELOG top all on 0.41.10.0.

Existing markdown / frontmatter / manual links still count toward backlink-boost. NULL-source legacy rows still count (the `IS DISTINCT FROM` form is NULL-safe per the `[sql-neq-misses-null-drift]` learning). +- **Cycle integration is deferred.** v1 is CLI-only; `auto_link_mentions` config gate dropped from v1. Run `--by-mention` manually or via cron. Cycle-phase wiring is TODO-2 (P2 follow-up). +- **Pack-aware gazetteer is deferred.** Hardcoded entity types for v1: `person`, `company`, `organization`, `entity`. User-defined schema-pack entity types (e.g. `researcher`) won't be auto-linked until TODO-1 (P2 follow-up) lands. +- **Self-link guard is on.** An entity page mentioning its own title (e.g. body of `companies/acme.md` says "Acme has 500 customers") will NOT auto-create a self-link, avoiding fake orphan-reduction. +- **Cross-source guard is on.** A page in source A mentioning an entity in source B will NOT auto-link in v1 — deliberate isolation. Can relax in a future wave if real cross-source linking is needed. +- **Ignore list at gazetteer-build time, not match time.** Built-in ambiguous tokens (Apple, Amazon, Square, Stripe, Box, Meta, Target, Oracle) are dropped from the gazetteer ONLY when no corresponding entity page exists. If you've explicitly created `companies/apple`, the auto-link fires (your intent wins). +- **FS-source + `--by-mention` rejected.** The gazetteer needs the engine; FS-walk + DB-gazetteer is incoherent.
