No + * priority resolution, no engine fallback — ever. + * 2. `system.` reaches an engine scalar, and ONLY an engine scalar, + * and ONLY when spelled explicitly. The addressable entity map is exactly + * ten names: id, type, subtype, createdAt, updatedAt, confidence, weight, + * visibility, service, createdBy.

The engine's fields moved behind `system.`.** The engine still keeps +its own per-record bookkeeping — creation time, type, confidence, and so +on. Those are reached one way only now: spelled out, e.g. +`system.createdAt`, `system.type`. They are just as queryable and sortable +as before. `orderBy: 'createdAt'` means *your* field named `createdAt`; +`orderBy: 'system.createdAt'` means the engine's timestamp. No guessing, +no priority rules. + +**3. Storage keeps the two physically separate.** New records store your +metadata in its own nested compartment, so a user field named +`confidence` and the engine's confidence live side by side, both intact, +through restarts, index rebuilds, and `asOf()` history. Old records stay +readable forever; nothing rewrites your data. + +**4. Mistakes are loud.** An ambiguous or unknown field name is a typed +error naming the fix.

The stamp used to advance only at close(), so a long-lived writer that flushes but never closes — the primary production shape — left every write window behind the stamp, and ANY unclean exit forced a whole-store backfill walk (per-entity work, measured >60s and door-starving on a 9k-row production brain) on the first stats call. (b) BEHIND-stamp adoption becomes adopt + INCREMENTAL CATCH-UP: the exact missing window (stamp, committed] resolves its affected-id set from the fact log and reconciles each entity with time-travel before/after reads (asOf at both window bounds) through the same delta algebra the live hooks use — cost bounded by writes since the last flush, never store size, and exact under interleaving because reconciliation targets the FIXED window end while later writes chain through hooks. Oversized windows (>5000 affected) and unreadable windows demote to the announced rescan — never a silent partial serve. (c) The native provider's parallel rebuildAggregate — on the contract since 8.x but never invoked anywhere — is now the backfill walk's preferred door: one call per aggregate with source-matched entities, replacing the per-entity FFI stream. (d) A delete whose before-image is unavailable can no longer SKIP the aggregation hook silently (counts drifted upward forever): both delete paths (remove() and transact) flag an exact rescan, loudly. Pins: integration (flush stamp; unclean-exit reopen → exact counts through an add + group-move + delete window with the walk spy proving ZERO whole-store walks) + unit (provider rebuild invoked once with filtered entities; flagAllForRescan; reconcile delta algebra).

The native pair widened that window to seconds in production before their side's visibility-commit fix; the structural cure lands here: - hnswIndex.updateItem: absent → add; SAME vector → pure no-op (the production shape — a type-only update re-indexed an unchanged vector, remove+add did pure damage); changed vector → the node NEVER leaves the index: synchronous vector swap first (every query from that instant sees correct distances), then unlink/relink at the node's existing level via shared internals (linkNode/unlinkNodeEdges refactored out of add/remove; entry point and maxLevel provably unchanged). - ReplaceInVectorIndexOperation: ONE transaction leg; feature-detects provider updateItem (native seam flagged — their side ships updateItem, then the adjacent remove+add fallback is dead code). Both update staging sites swapped; delete sites untouched. - LAZY-OPEN GATE (fleet adoption find, SELF-ENGINE-PAIR-STANDARD): under disableAutoRebuild, ensureIndexesLoaded assessed ONLY the vector index — a not-ready native METADATA provider never blocked the completion latch and every find() silently returned [] on a populated store.

charset=UTF-8 Content-Transfer-Encoding: 8bit A3 of the service-class pair (BRAINY-PROD-LATENCY-TRIAD): a VFS file write ran the embedder synchronously while the caller waited — 5.6s p50 / 21.4s p95 per small file on a production deployment, the dominant stage of every capture write. - add()/update() gain deferEmbedding: the write acks at durability (data + metadata persisted, a DURABLE pending marker under _system/pending_embeds/ written BEFORE the commit — orphan-safe direction); the single-flight background worker embeds the CURRENT data and swaps the vector in ATOMICALLY (ReplaceInVectorIndex — the row is never absent from search; a deferred UPDATE keeps serving the OLD vector, stale-beats-absent per the flicker law). Typed refusals: defer+vector, defer-without-data. - CRASH-SAFE: markers are recovered at open by a BOUNDED prefix listing (never a store walk) and the worker resumes in the background — a crash can delay a vector, never lose one. A wedged embedder trips a LOUD 60s hang guard and the worker moves on (marker retained for retry). - The honest gauges: getIndexStatus().pendingEmbeds + pendingEmbedCount(); awaitPendingEmbeds() is the eventual-vector-index BARRIER for callers and tests that need searchability before proceeding. - VFS adopts it everywhere a write path could wait on the embedder: writeFile (both branches) and directory creation. Pinned in the strongest form: writeFile resolves while the embedder HANGS FOREVER. Pins: deferred-embedding 5/5 (ack law · stale-beats-absent · crash recovery across sessions · VFS hung-embedder ack · typed refusals).

Mon Sep 17 00:00:00 2001 From: David Snelling Date: Mon, 10 Aug 2026 09:29:21 -0700 Subject: [PATCH 040/229] =?UTF-8?q?fix(log):=20acked=20writes=20survive=20?=

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two release-blocking findings from the durability kill-matrix, both fixed in the owning layer: 1. LOG-AUTHORITY REPLAY AT OPEN: durable-at-ack fsynced the fact before the ack, but open() truncated every fact above the manifest — after a power loss that takes the un-fsynced tmp+rename canonical bytes, the acked write's ONLY durable copy was discarded. Now: under 'log' authority, open() REPLAYS intact facts above the manifest into canonical (FactLog.peekFactsAbove — CRC-gated, order-sorted) and advances the manifest to cover them; tree-authority brains keep the truncate contract they were promised. Pinned end to end: the power-loss row constructs the exact disk state (fsynced log, vanished canonical rename) and the acked write lives. 2. NO SILENT COMMIT: commitSingleOp buffered the generation BEFORE the fact append; an append failure (ENOSPC) rejected the caller but the next flush durably committed the generation with NO fact — a permanent silent log gap. Now the failure path un-buffers and returns the counter reservation: nothing commits, the log stays gap-free, and the canonical execute-residue orphan is the documented crash-equivalent. Plus: the kill-matrix itself (11 rows — every commit-path fault point × reopen-as-crash recovery contract, at-ack variants, disk-full row; five new zero-cost faultPoint sites), the log-authority pin suite (oracle green/red/state-differs, flip refusal, switch survives reopen, 9/9), and the group-commit covering pins (5/5).

Mon Sep 17 00:00:00 2001 From: David Snelling Date: Mon, 10 Aug 2026 10:55:11 -0700 Subject: [PATCH 045/229] =?UTF-8?q?feat(engine):=20the=20wiring=20wave=20?=

charset=UTF-8 Content-Transfer-Encoding: 8bit - Watermark stamping fans out at flush: all three projections stamped with the committed generation before their flushes persist. - waitForIndexed(path?, {generation, timeoutMs}) — the one honest read barrier for write-then-recall consumers; typed timeout error carries the pending count and names the gauge; getIndexStatus() gains per-projection gauges. awaitPendingEmbeds() unchanged underneath. - adoptLogAuthority() self-backfills curable divergences (pre-log records, witness drift) by identity re-commit before flipping — a fresh brain flips clean; log-ahead divergences still refuse loudly. - The verification oracle gains VERB legs (all four divergence classes; unwired = honest verbsChecked: 0, never a scope claim). - find({where: {}}) match-all serves (was silent-empty, warm AND cold; same fix in count/streaming/subgraph seeding); removeMany({where:{}}) refuses typed — a match-all bulk delete must be explicit. - Aggregation native envelope stamped via noteSourceGeneration before serializeState; the native-blob restore gates through the same adoption verdict as caller-side state (the unconditional adopt dies). - LC8 pinned: a wholesale directory move opens and serves identically across all three intelligences, with history traveling.

Also: decodeGroupV2 discriminated pad filler by RECORD COUNT, silently swallowing legitimate empty commits (an all-deduped batch at a real generation). Pads carry generation 0 — which writers can never mint — so the generation is the honest discriminator; empty commits stay visible.

Crash recovery is now a FOLD of the log (pending without a matching landed = recovered), skipped wholesale on brains with no v2 history; the one-time legacy bridge folds existing sidecar files in, migrates them as one fact, and deletes them — idempotent under a crash mid-bridge. No code path writes the sidecar again. Plus the ENTITY-TRUTH digest law, found by this train's own pins: canonical vector wrappers denormalize HNSW residue (connections + the randomly-assigned node level) that the log deliberately does not carry — the verification oracle digested it and would have reported false state-differs on ~any nonzero-level node (a ~15% flake in the cutover pin was the symptom). Both sides of every oracle comparison now normalize to entity truth (nounEntityTruth); index residue has its own rebuild path and is not entity state.

The law now: an idle fire landing within the spacing floor of the last flush DEFERS to the floor boundary instead of flushing; the floor is min(interval, 10× the CONFIGURED idle window) — scaled to caller intent (a tiny idle window keeps fast idle-driven durability; default 2s/30s config gets a 20s floor), derived from the configured idle, never from a deferred re-arm delay (which would compound into runaway deferral). Deferred is never dropped: a lone write on a then-quiet store still persists at the floor without any further write arriving.

WHOLE-LOG REPLAY ON UNCLEAN OPEN (the big one): log-authority replay only covered facts ABOVE the manifest — but live canonical entity writes are tmp+rename without per-file fsync, and the group-commit flush syncs staging + manifest, never the live tree. Power loss could therefore vaporize acked canonical bytes BELOW the manifest while the log held every fact scan-clean (measured: 299 of 301 acks lost). Now: a clean close stamps a clean-shutdown marker (fsynced, written last); every open consumes it; an UNCLEAN open under log authority folds the ENTIRE log into canonical — whole-entity after-images make the re-apply idempotent and byte-safe. Zero cost on the happy path; crash recovery pays one narrated fold. Recovery is replay: a crash is just bigger lag. 2. TORN WRITER LOCK: power loss legally leaves the lock file present but empty; the parse failure read as 'no holder' while the O_EXCL claim EEXISTed forever — a PERMANENT lockout no staleness check could clear. An unparseable lock is stale by definition (no live holder has one): unlink loudly and re-loop; a racer rewriting a valid lock first wins. 3. PAIR GUARD: flush() called metadataIndex.stampWatermark unguarded; a replacement metadata provider without the method killed the pair at first flush. All three stamp calls are optional-chained — a missing stamp is a verdict-side rescan, never a flush crash. Pins: whole-log fold restores rows vanished below the manifest · clean-shutdown marker lifecycle (stamp/consume/re-stamp) · torn-lock recovery with a fresh write after · stampless-provider flush.

The oracle gates the flip exactly as the guarded adoption path always did — curable divergences baseline-backfilled, the flip lands ONLY on a green verdict — and a brain that cannot verify STAYS tree-authoritative loudly, with the refusal recorded on the switch artifact so subsequent opens are cheap. config logAuthority: 'defer' is the explicit documented opt-out (no automatic adoption; declared flush-window loss; adoptLogAuthority() flips later). A stored artifact always wins. RELEASES.md carries the posture. Two standing .fails debt pins FLIP TO HOLDING under the default: the at-ack crash-survival gap and the ack-at-log durability target — both now permanent asserted truths, not aspirations. POWER-CUT THROW SITES (fault-injection findings, brainy-alone config): - A manifest-listed-but-unloadable column segment QUARANTINES at discovery (loud once, counted always, quarantinedSegments() exposed for the heal) and the field serves its remaining segments DEGRADED — never a raw throw killing every query on the field. Real storage faults still propagate untouched. - Torn generation artifacts (NaN/garbage in manifest or counter) DISCARD with narration at the store's open and recovery re-derives — plus a defensive finite-integer guard at the init consumer. Never a RangeError killing an open. THE LOUD TORN-RECORD CONTRACT: an existing-but-unparseable stored record now surfaces as a typed, counted TornRecordError on every entity-read surface (including fifteen previously-blind per-item batch catches); ENOENT stays clean-absent; artifact readers with designed absent-recovery keep null-tolerance behind the loud floor. Disk corruption can no longer read as silent data invisibility. Suite migration: the default's pins inverted deliberately, generation baselines made relative, quarantine-contract pins rewritten to the ruled behavior.

The boundary, redrawn: - IDENTITY READS (get-by-id of a specific record, CAS blob point-get): typed TornRecordError, unchanged — a caller who asked for THAT record can act on the answer. - SET-SHAPED READS AND WALKS (enumeration, pagination, batch hydration — the paths recovery rebuilds and finds page over): HEAL PAST the torn victim. The adapter's loud floor (error log + counted gauge) fires at the encounter; the walk serves the remaining rows. One crash casualty can no longer kill every query on its shard — or the open itself. - WRITES OVER TORN RECORDS ARE THE CURE: the save path's read-merge, the commit path's before-image capture, and the operations' rollback captures all treat a torn prior as the create sentinel, narrated — the incoming bytes replace the unreadable ones, and history for the id honestly restarts at that generation. Corruption can never block its own heal. - THE NaN SOURCE: torn mapper state (nextId/entries carrying garbage) discards with narration and re-derives via the existing rebuild path; the mint gains a source guard healing a non-integer counter from the live map. The reopen and first-write RangeError shapes are dead at the source, both authority branches. Pinned with the exact fault-injection scenarios: a torn entity record (including the VFS root) no longer kills the open — walks heal past it, the keeper rows serve, and the identity read of the victim itself is typed-or-healed; a torn mapper reopens and mints sanely on the first post-recovery write.

The exemption, at both mint seams (the host's minter thunk and the fact log's encoder guard): int 0 is legal iff the id is the reserved root; zero for ANY other id remains a corrupt-mint refusal naming the reserved exception. The codec's u64 layer already tolerated 0 — only the guards over-refused. Pins: adoption goes green on a brain whose VFS root carries int 0 (the depot-brain shape, previously refused) · a non-root zero still refuses typed at the mint seam — held at the seam itself because a full write SELF-HEALS a poisoned zero (the index cycle re-mints before the fact is written, which is the correct outcome and was verified in the pinning).

In practice the crash-safe default reached zero existing brains: the exact outcome the hold ruling forbade. The cure: the backfill now rewrites canonical in the LAW SHAPE — exactly the wrapper the log's reconstruction produces (denormalized enumeration fields derived from the metadata leg, which is their authority under the field-addressing law; the embedding floats ride through byte-identical; adjacency residue keeps its own rebuild path). The oracle then verifies the rewrite before the flip — the same safety, no operator chore. Log-ahead divergence classes (a log the witness denies) still refuse loudly, exactly as before. Classification note for the record: the flagged uuid-v7 rows postdate the fact log's introduction, so they classify as state-differs (in-log, drift-shaped) rather than pre-log — both classes ride the same backfill.

The ruled cut: a WHERE filter naming a field no row carries is SERVED OPERATOR-TRUTHFULLY — eq/in/range/contains answer [] (nothing carries it, nothing matches); ne and exists:false answer ALL rows (the equally true complement — a blanket empty here would be silently wrong, which is why the simpler cut was rejected); exists:true answers []. Served from the field registry, with the did-you-mean demoted to a once-per-field WARN. orderBy and genuinely ambiguous addresses KEEP their hard typed refusals: no truthful order exists over an uncarried field, and ambiguity is a contract error while absence is data. Mechanics: the negative operator absorbs the FIELD_NOT_INDEXED throw as its empty exclude set (the clause-level catch correctly zeroes positive operators only); the egress matcher already agreed. Plus the provider-seam belt: a field refusal thrown by a replacement metadata manager is normalized to THIS package's UnresolvableFieldError at every filter call site — one class identity for consumers, instanceof works (a first adopter's cross-package finding). Conformance: tests/conformance/sparse-store-cut.test.ts — the shared operator rows both engines run (positive-empty, negative-all, fresh-tenant day-one, orderBy refusal kept, compound composition).

PAD-FRAME CONSTRUCTIBILITY: a single msgpack bin filler steps its header by one byte at each size class (bin8→bin16→bin32), leaving one unreachable payload size per boundary — the sealer requested a 291-byte pad, the encoder threw 'not constructible', and sync() died whole. Construction is now TOTAL: the class-boundary holes bridge with a trailing fixint beside the bin ({bin(n)} ∪ {bin(n)+fixint} covers every size ≥ minimum). Pinned exhaustively: every size from the minimum through a full sector plus boundary spill constructs byte-exact and decodes as reader-invisible filler. 2. THE NON-MONOTONIC REFUSAL LOOP: the append-failure compensation rewound the generation counter on ANY throw — including a covering SYNC failure after a SUCCESSFUL append. The log carried generation N while the counter re-minted N, and every later append refused 'non-monotonic (N ≤ head N)' — the write path wedged in a refusal loop through deferred-embed retries and flush backoff. The compensation now splits by phase: an append failure (log never took the fact) fully compensates — un-buffer and rewind; a sync failure after append earns the rewind ONLY if the appended fact is provably dropped, otherwise the generation stays consumed and buffered — the counter never re-mints a number the log may carry. Pinned: an injected one-shot sync failure fails its write loudly and the very next write mints fresh and succeeds, with the log scanning strictly ascending end to end. Also probed against the adopter's carried report: the 9.0 vfs.rename stale-ghost shape does NOT reproduce on this head (old path cleanly unresolvable on exists/stat/readdir after rename).

charset=UTF-8 Content-Transfer-Encoding: 8bit Two defects with one root, found by the fold-checkpoint work's first integration gate. (1) THE RACE: restore() never quiesced the generation store, so a background flush could write into _system/ while the swap was removing it — observed as ENOTEMPTY mid-swap when a checkpoint stamp landed between readdir and rmdir. The swap now runs inside the store's exclusive section (runStateReplacement): flush timer disarmed, pending tier and checkpoint accumulator discarded BEFORE any directory moves. (2) THE INHERITED ASSERTION: a snapshot carries its source brain's clean-shutdown marker and fold checkpoint, but the restored files were bulk-copied without per-file fsync — the inherited stamps would suppress exactly the recovery fold that cures a post-restore power cut. reopenAfterRestore now deletes both stamps before reopening: the open treats the store as uncleanly shut, folds the restored log into canonical, barrier-syncs what it re-applied, and stamps fresh — the restored state is durably founded at restore time instead of borrowing assertions about bytes this disk never synced. Pinned: restore under in-flight traffic completes; the pre-restore stamp does not survive; the post-restore stamp is the reopen fold's own, at the restored watermark. --- src/brainy.ts | 8 +++- src/db/generationStore.ts | 43 +++++++++++++++++++ .../integration/fold-checkpoint-bound.test.ts | 35 +++++++++++++++ 3 files changed, 85 insertions(+), 1 deletion(-) diff --git a/src/brainy.ts b/src/brainy.ts index dc97b82f..d7313855 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -9229,7 +9229,13 @@ export class Brainy implements BrainyInterface { } const floorGeneration = this.generationStore.generation() - await this.storage.restoreFromDirectory(path) + // The swap runs inside the generation store's exclusive section: pending + // flush timers are disarmed and buffers discarded BEFORE any directory is + // removed, so a background flush can never write into `_system/` mid-swap + // (the ENOTEMPTY race a checkpoint stamp once hit). + await this.generationStore.runStateReplacement(() => + this.storage.restoreFromDirectory(path) + ) await this.generationStore.reopenAfterRestore(floorGeneration) // If the entity-id mapper is a NATIVE provider with a `rebuild()`, reload it diff --git a/src/db/generationStore.ts b/src/db/generationStore.ts index 837ea90a..4002c1ba 100644 --- a/src/db/generationStore.ts +++ b/src/db/generationStore.ts @@ -3127,6 +3127,28 @@ export class GenerationStore { * are never reissued. * @param floorGeneration - The counter value before the restore. */ + /** + * @description Run a wholesale state replacement (the restore swap) + * EXCLUSIVELY: under the commit mutex, with the pending flush timer + * disarmed and the pending tier + fold-checkpoint accumulator discarded + * FIRST — so no background flush can write into `_system/` while the + * replacement is removing and swapping directories.

(1) TX-LOG ORIGIN: engine- originated commits stamp an optional origin on their tx-log entry AND the commit fact's meta — 'system:embed-landing' (the deferred vector landing), 'system:adoption-backfill' (baseline re-commits), 'system:reconcile'. A downstream activity feed showed a double tick because the landing commit was indistinguishable from a user save, and the consumer rightly refused a time-window collapse as a quiet loss; feeds now filter on fact. User writes stay unstamped — absent origin is the user shape, every existing consumer unchanged. (2) reconcileLogDivergence(id, {attest}): the human's door for log-live-canonical-absent, the one class adoption refuses by design because a lost-tombstone deletion is indistinguishable from canonical loss. 'deleted' mints the missing tombstone (history keeps the earlier live record); 'restore' folds the log's only copy back into canonical; wrong- class calls refuse typed with nothing written.

evicted writers are fenced at every commit barrier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The production dev-store split-brain (two live writers alternating a store's id-mapper between two internally-consistent truths), cured at all three of its roots. (1) STALENESS REQUIRES PID-DEATH: the old rule evicted on heartbeat age alone, so a >60s event-loop stall (debugger pause, GC, heavy sync work) handed the lock to a second opener while the first kept writing; a live process is now never auto-evicted — a wedged-but-alive holder is the operator's call via {force:true}, and the heartbeat stays for observability. (2) THE CLAIM IS ATOMIC: writeFile(wx)'s open→write→close left an empty-file window a concurrent opener could read as torn, unlink a LIVE claim, and take the lock; the claim is now tmp-write + hard-link — the lock appears with its full contents in one step. (3) THE FENCE: every flush commit and transact barrier verifies lock ownership first (one small read per window) — a forced-out or lock-deleted writer fails typed (BRAINY_WRITER_FENCED) before a single staged byte or manifest advance, instead of writing on unaware. Pinned: live-with-ancient-heartbeat refuses typed; dead-PID self-clears narrated; a forced-out writer's flush and transact both fence, advancing nothing. Requested by a downstream team as single-writer guard or loud lockout — this is both. --- src/db/generationStore.ts | 9 ++ src/db/types.ts | 10 ++ src/storage/adapters/fileSystemStorage.ts | 71 ++++++++-- src/storage/baseStorage.ts | 12 ++ tests/integration/writer-lock-fencing.test.ts | 131 ++++++++++++++++++ 5 files changed, 225 insertions(+), 8 deletions(-) create mode 100644 tests/integration/writer-lock-fencing.test.ts diff --git a/src/db/generationStore.ts b/src/db/generationStore.ts index 7439a025..065b3659 100644 --- a/src/db/generationStore.ts +++ b/src/db/generationStore.ts @@ -1394,6 +1394,10 @@ export class GenerationStore { // The transaction's entire canonical footprint is now durable, so the // counter/manifest advance below can never outrun the entity bytes. await this.storage.flushWriteBarrier?.() + // THE FENCE (transact leg): verify lock ownership before the commit + // point — an aborted-by-fence transact rolls back cleanly through the + // catch below; a fenced writer must never advance counter or manifest. + await this.storage.assertWriterFenceHeld?.() faultPoint('after-execute') // Fact log (dual-write): append + fsync this generation's AFTER-IMAGE @@ -1915,6 +1919,11 @@ export class GenerationStore { private async flushPendingSingleOpsUnlocked(): Promise { return this.withMutex(async () => { if (this.pendingGens.length === 0) return + // THE FENCE: an evicted writer (force-takeover, removed lock) must fail + // HERE, before a single staged byte or manifest advance — writing on + // after eviction is how split-brain stores are made.

Every budget is now at least 3x the worst measurement observed across three machines, each with a comment naming its calibration basis; the find-unified micro-comparison of two sub-millisecond timings becomes a ratio assertion (absolute equality of microsecond pairs can never be stable). The inference-bound trim-history correctness test gets a timeout covering its slowest observed run (174s) — its assertions are exact and untouched. These remain order-of-magnitude guards; real perf enforcement lives in the dedicated perf lanes with iron-specific budgets, per the gate-speed standard.

(1) THE FOLD MATERIALIZED THE LOG: peekFactsAbove(0) decoded every fact into one array (GBs of after-images on a ~7k-fact log, a GC storm, a starved write lane). The fold now STREAMS one segment-batch at a time — memory is one segment at any log size — with structural ordering asserted loudly. (2) THE FOLD WAS SILENT UNTIL DONE: minutes of boot work with zero narration is what invited the restarts. It now announces itself BEFORE the work ('do not restart, the fold is finite') and prints progress every thousand facts. (3) THE CHAIN COULD ONLY ARM AT A CRASH: a live mid-session flip left the fold checkpoint unfounded, so the brain's first unclean boot paid a whole-log fold. Adoption now founds the checkpoint AT THE FLIP — one paged full canonical barrier (bounded memory), then the stamp — so bounded recovery holds from minute zero for every store that flips, at any size. Pinned: a non-fresh flip stamps immediately; the first post-flip unclean boot folds bounded (an unflushed at-ack fact above the checkpoint is restored; a barrier-covered row below it is outside the fold).

Nothing had crashed. "The recorded pid is gone" is equally true of an orderly restart and of a crash, so the verdict could not tell an operator which one they had — and when the OS recycles a pid it fails the other way, refusing to open a store whose writer died days ago. Three changes, all at the law: - close() is two parts, and the second is unconditional. The durable steps (flush, markers, component close, plugin deactivate, buffer drain) move to closeDurableSteps(); the terminal releases — the flush-request watcher, the WRITER LOCK, the VFS timers, the terminal `closed` flag — always run. The original failure is narrated with what it costs the next open, then rethrown. - releaseWriterLock() writes a CLEAN-CLOSE RECORD (`locks/_writer.close`) naming the lock generation it released; the next claim consumes it, so a record can never vouch for a later crash. An open reads the record instead of guessing: recorded → nothing to recover; absent → say so, and name the crash recovery this open will now run. - The signal path stops failing in a batch. It was one try around a loop over every open brain, so the first instance whose flush rejected stranded every remaining brain's lock and markers — at exit code 0. Now: per-instance isolation, the generation store's close (the clean-shutdown marker, without which the next open folds the whole log) is part of shutdown, the lock is given up in a finally, and the handler no longer calls process.exit() when the host application has its own signal handler — that race truncated the host's own close() mid-flight. Pins: tests/integration/writer-lock-clean-close.test.ts — completed close leaves no lock and a consumed-once record with a silent reopen; a failing durable step still releases and still rethrows; SIGKILL leaves the lock with no record and the reopen names the crash; a host SIGTERM handler runs to completion.

Two defects, both fixed here. The narration was written to `prodLog.warn`, and every environment that looks like production clamps the logger to ERROR — so the phase breakdown that would have named the slow phase was composed and thrown away. `prodLog.narrate` is always visible, like `error`: it carries the two things an operator is entitled to hear from a database regardless of a cost setting — why it is slow and what it is doing about it. `silent: true` still silences it; that is a request, not a default. And nothing spoke DURING a phase, only after the whole open. init() now runs an unref'd heartbeat that every 5s names the phase currently running, its elapsed wall and what it is paying for, plus one line per phase as it ends for any phase over 2s. The generation-log fold's own progress and completion lines move to the same channel and now carry their wall — they were invisible in production, which is how an operator came to restart a converging fold three times. Pins: tests/integration/open-narration.test.ts — narrate() survives the clamp that silences warn(); a 6.5s storage-init produces a heartbeat naming the phase and a completion line naming its wall, with the logger clamped to ERROR. --- src/brainy.ts | 70 ++++++++++++-- src/db/generationStore.ts | 13 ++- src/utils/logger.ts | 20 ++++ tests/integration/open-narration.test.ts | 114 +++++++++++++++++++++++ 4 files changed, 202 insertions(+), 15 deletions(-) create mode 100644 tests/integration/open-narration.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 957920f5..81f3cc7e 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -1098,21 +1098,67 @@ export class Brainy implements BrainyInterface { configureLogger({ level: LogLevel.DEBUG }) // Enable verbose logging } - // OPEN-PATH NARRATION: lightweight phase timing across the five - // named stretches of init — storage init / generation-store open+fold / - // index init+gate / VFS bootstrap / embedding-warm-started.

Two copies of the same archive derived different numbers (14,231 and 14,081), because each had been persisted at a different moment under the old rule that counted one entity per id DIRECTORY. A downstream index heal subtracted against that denominator and reported remaining work that did not exist. The scan already applies the right predicate — one entity per IDENTITY RECORD (the metadata content leg), shared with pruneOrphanedEntities so the two agree by construction. What was missing is that a ledger persisted under the old rule was only FLAGGED suspect and then went on serving its wrong numbers for the life of the store, waiting for an operator to run repairIndex. - The ledger now derives itself honestly in the BACKGROUND after the open, narrating start and finish with the correction it made. Background because these scalars are denominators — no read is served from them — and because walks exactly like these are how a 24,898-id store spent minutes of a restart in silence. Observable via whenCountLedgerSettled(); nothing in the read path waits on it. - A derivation that raced a write refuses to stamp its number "exact": one retry on a quiet store, then the ledger stays SUSPECT and says so, naming repairIndex as the door that recounts under a barrier. - The one derivation that CANNOT leave the foreground says why it cannot: getNounCount()/getVerbCount() are served from it, and a background walk would make a populated store answer "0 entities" — a wrong answer, not a slow one. It narrates its start and its wall instead. - counts.json is written temp+rename. A truncating write left a window — measured at roughly 750ms after a flush or close — in which a concurrent reader saw the file EMPTY; an unparseable ledger sends the next open down the full-rescan path, so the cheapest file in the store was buying the most expensive recovery. - The writer lock's clean-close record is now consulted before the same-process branch too: a restart reported "Re-acquiring writer lock ... this is a bug" immediately after a clean close, sending an operator after a leak that did not exist.

The cause is a missing distinction: a provider reporting serving:false because it is BUSY BUILDING ITSELF and one reporting serving:false because it is BROKEN looked identical through healthReport(), and both were answered the same way — call rebuild(), and wait for it. The contract that tells them apart is one optional, synchronous, O(1) hook: `rebuildInProgress(): ProviderRebuildProgress | null`, reporting a phase name and whatever the provider actually measures (done/total/startedAt) — never an estimate dressed as a fact. A provider without the hook behaves exactly as before. With it, a provider owns its own rebuild: - the open gate neither starts a second rebuild nor waits for the provider's, and narrates that it is not waiting and what will refuse meanwhile; - init() returns and every other family serves; - that family's doors refuse BY NAME, carrying the provider's own progress, and say plainly that the door opens by itself and no action is needed — distinct from a broken index, which names repairIndex(); - the epoch stamp does not advance while any family is still being built. Nothing is ever served empty: a not-serving family refuses, as it already did. Pins: tests/integration/open-does-not-wait-for-a-rebuilding-provider.test.ts — init() returns in milliseconds against a provider claiming a 6s rebuild, brainy starts no rebuild of its own, a filtered read refuses naming the phase and the 4,096/14,056 progress, and the door answers once the provider reports serving. The pin fails loudly rather than vacuously if its stub never installs. --- src/brainy.ts | 85 +++++++++- src/utils/indexReadiness.ts | 80 ++++++++++ ...not-wait-for-a-rebuilding-provider.test.ts | 145 ++++++++++++++++++ 3 files changed, 306 insertions(+), 4 deletions(-) create mode 100644 tests/integration/open-does-not-wait-for-a-rebuilding-provider.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 013885ff..92702364 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -198,7 +198,12 @@ import { import { isDeterministicEmbedMode } from './embeddings/deterministicEmbedMode.js' import { GenerationConflictError, StoreInconsistentError } from './db/errors.js' import { BrainyError, GraphIndexNotReadyError, MetadataIndexNotReadyError, MigrationInProgressError, VectorIndexNotReadyError } from './errors/brainyError.js' -import { assessIndexReadiness, assessProviderHealth } from './utils/indexReadiness.js' +import { + assessIndexReadiness, + assessProviderHealth, + assessProviderRebuild, + describeRebuildProgress +} from './utils/indexReadiness.js' import { reconstructNounWrapper } from './db/factLog.js' import { asBrainyFieldRefusal } from './db/fieldAddressing.js' import { @@ -4540,6 +4545,19 @@ export class Brainy implements BrainyInterface { this._graphAdjacencyVerified = true return 'live' } + // A provider that is REBUILDING ITSELF gets a refusal that says so, + // with its own progress: open deliberately did not wait for it (see + // rebuildIndexesIfNeeded), so this door is temporarily closed and will + // open on its own.

The open gate's consistency check — "metadata index has 0 entries but storage has N entities" → CRITICAL + a forced second rebuild — knew two states, migrating and not. A provider whose rebuild() returns once the rebuild is OWNED AND RUNNING ONLINE (its doors refusing by name while other families serve) legitimately reports 0 entries there, so every first contact printed a false CRITICAL and kicked a redundant second rebuild. The exemption rides the rebuild-progress hook, NOT isMigrating() — widening that would hold every write and 503 the whole brain through the migration snapshot, which is worse than the false alarm. The check's real class is untouched: a provider reporting 0 entries with no rebuild in progress still trips it. The crash-recovery rebuild kick gets the same deference: a provider already rebuilding itself from canonical is doing exactly that work, and the fold ran in the generation store's open before any provider existed, so what it is reading is the repaired canonical.

DECLARED: package.json carries "brainyContract": 1 and the engine states its own via contractVersion() / BRAINY_CONTRACT_VERSION — two engines compare an integer instead of probing prototypes, and a tool reads the package field without importing the engine. Pinned so the two can never drift apart. SERVED: hasAll, noneOf and excludes now work on the index path. The defect underneath was worse than the reported divergence — the metadata index's operator switch had NO DEFAULT CASE, so any operator without a case left the field's match set at its initial [] and find() returned an empty page. Documented, validator-accepted, matcher-implemented operators answering silently wrong. hasAll intersects each element's posting set (an empty operand is vacuously true of every row that has the field), noneOf complements their union, excludes complements contains. REFUSED BY NAME: startsWith, endsWith, matches and length raise INVALID_QUERY naming the operator, the field and the reason. An equality/range posting index cannot evaluate a substring, a pattern or an array length without reading every row — which is the cost this path exists to avoid — so it refuses rather than answering an empty page. Both engines now agree on all 25 tokens and contract 1 has no remaining operator divergence. This is a visible change for a consumer calling those four through find({ where }): an empty page becomes a typed refusal. EMITTED: scripts/emit-contract-manifest.mjs generates docs/api-contract.json from the BUILT surface — prototype doors, exported error classes, the operator sets read out of their single definitions, the field-addressing vocabulary, the health verdicts. Nothing hand-maintained, so a diff between two manifests is a diff between two engines. `--check` fails on a stale manifest, which makes the announce-every-addition duty mechanical rather than remembered. RATIFIED in docs/contract-1-ratification.md: the 41-of-57 required split with the promise spelled out (a refusal is part of a door; deprecation is not removal), the serving-withholding list confirmed exhaustive and identical, the minor/major rule adopted with the announcement duty, the 30 storage seam methods committed as supported surface until Stage 2, and a finding filed against the spec — is / isNot / greaterEqual / lessEqual are listed there as served aliases and have never existed in this engine, which throws INVALID_QUERY on all four. --- docs/api-contract.json | 1545 +++++++++++++++++

What dominates it is a migration sweep — a filtered find() over the whole store hunting for root directories created before the fixed root id existed. A store either carries such duplicates or never will, and the sweep ran on every open, forever, in the foreground. It is now caused by the store's state instead of by the open count: a durable marker under _system/ records that the sweep has run, and a store carrying it never sweeps again. A store without one sweeps in the BACKGROUND — the sweep only removes duplicate roots, nothing serves from them, and it was already declared non-critical — narrated at both ends, with whenRootSweepSettled() for anyone who needs to observe rather than race it. An adapter with no raw-object door keeps the old behaviour: correctness over cost, never a silent skip.

This is what it was doing. Discovering which generations exist on disk called listRawObjects('_generations'), which RECURSES the whole tree and returns every file in every generation directory — to extract a set of integers that the top-level directory NAMES already spell out. The cost scales with the entire history, is paid on every open, warm or cold, and grows for the life of the store. A one-level door — listRawPrefixes(prefix), the immediate child directory names — is added to the storage seam. The filesystem adapter answers it with a single readdir; BaseStorage derives it from the recursive listing, so an adapter without a cheap implementation is never wrong, only never faster; and the generation store falls back to the old listing when the door is absent. One behavioural difference, stated: an EMPTY generation directory is now discovered where the file listing could not see it. Above the committed watermark that is a crash scar, and recovery already has an explicit branch for it ("indeterminate partial dir" — dropped, narrated). Below it, it becomes a resolvable generation holding no records, which is what an empty generation means. Suites: the durability kill matrix (15), db-mvcc (30), history repacking (4), rollback trapdoor (3), entity-tree stamp (4) and the full unit suite (2,105) all green. --- src/db/generationStore.ts | 27 ++++++++++++++++++----- src/db/types.ts | 15 +++++++++++++ src/storage/adapters/fileSystemStorage.ts | 24 ++++++++++++++++++++ src/storage/baseStorage.ts | 23 +++++++++++++++++++ 4 files changed, 84 insertions(+), 5 deletions(-) diff --git a/src/db/generationStore.ts b/src/db/generationStore.ts index d925c9e0..fd052c31 100644 --- a/src/db/generationStore.ts +++ b/src/db/generationStore.ts @@ -537,12 +537,29 @@ export class GenerationStore { this.horizonGen = finiteGen(manifest?.horizon, 'manifest horizon') this.counter = Math.max(finiteGen(counterFile?.generation, 'generation counter'), this.committed) - // Discover existing generation record directories. - const recordPaths = await this.storage.listRawObjects(GENERATIONS_PREFIX) + // Discover existing generation record directories — BY DIRECTORY NAME. + // This used to call listRawObjects(), which recurses the whole + // `_generations/` tree and returns every file in every generation, to + // extract a set of integers the top-level directory names already spell. + // MEASURED on a real store with an 11 GB generation history: the phase + // this sits in cost 55,538 ms of a WARM REOPEN after a clean close, with + // no fold to blame — this walk is what it was doing.

THE FLUSH-REQUEST WATCH (the strongest of them). It readdir'd the request directory every 500 ms, per brain, for the life of every writer — armed on every non-reader brain whether or not any inspector process existed. In a process holding many stores that is tens of directory reads per second on a completely idle service, plus a stale-request GC on every one of them. It now uses fs.watch, so the arrival itself wakes it and a request is seen SOONER than the poll saw it. Two concessions ride along, both stated in the code: a 30s safety sweep (fs.watch drops events on some network and fuse filesystems, and the GC needs a tick of its own — two orders of magnitude fewer reads than the poll made), and a fall back to the original 500 ms poll, narrated, on a filesystem that cannot watch at all, because an inspector whose request is never seen waits forever. THE WRITER HEARTBEAT goes 10s → 60s. It is observability ONLY — staleness is decided by pid liveness and the fence compares pid + hostname, so no decision anywhere reads the timestamp — and at 10s it was a lock-file write every ten seconds per brain forever, for a value nothing computes with. An operator still sees a heartbeat inside the minute. THE HEALTH NARRATION dedupes by CONTENT, not by the provider's generation counter. That counter bumps on every ledger mutation and rebuild boundary, so a provider bumping it on routine work re-emitted the same unchanged line on every read, while one that never bumped could suppress a line whose reasons had genuinely changed. The generation is still reported; it no longer decides whether the line is worth saying. CORRECTION, and it is against my own earlier claim: the idle-flush commit read a reported idle-CPU observation (many stores, no writes, a flush every ~35s, over a core burned) as caused by the flush path. That does not follow — this engine's cadence is write-driven (every trigger runs through noteWriteForPersistence, which only a committed write calls), so something was CALLING flush() on those brains and the caller is still unidentified. The clean-flush gate makes such a call free; it does not account for it. The code comments and the idle lane now say exactly that.

THE HEALTH-GATE PIN encoded the old law — "narrates once per generation, twice across a generation bump" — which the content-keyed dedupe deliberately replaced. A provider's `generation` bumps on every ledger mutation and every rebuild boundary, so keying narration on it re-printed an unchanged health line on every read that consulted a busy provider, and let a provider that never bumped suppress a line whose reasons had genuinely changed. The pin now asserts BOTH directions: an unchanged verdict stays silent however the counter moves, and a changed verdict is always heard. THE VFS HYBRID-SEARCH SUITE configured its store with `options.basePath`, an alias removed at the 8.0 major that configures nothing. The suite was therefore never using its temp directory — it opened the DEFAULT store, shared with every other run on the machine, and accumulated tens of thousands of rows until it failed on that shared store's graph adjacency instead of on anything it tests. It now passes `storage.path`. The suite drops from 6.5s to 0.3s, which is the measure of how much foreign data it had been opening. Neither failure was caused by the release branch; the first is the branch's own behaviour change meeting its outdated pin, the second predates it. --- tests/integration/health-gate.test.ts | 20 ++++++++++++++++---- tests/integration/hybrid-search-vfs.test.ts | 8 +++++++- 2 files changed, 23 insertions(+), 5 deletions(-) diff --git a/tests/integration/health-gate.test.ts b/tests/integration/health-gate.test.ts index 1c9a642d..f2952116 100644 --- a/tests/integration/health-gate.test.ts +++ b/tests/integration/health-gate.test.ts @@ -188,7 +188,7 @@ describe('health gate (b) — unledgered is unknown: never blocks a serving prov describe('health gate (c) — degraded-but-serving narrates once per generation', () => { // PER-FAMILY LAW (10.4.1): a metadata find() consults the METADATA leg only — the // degraded report lives on the family the read actually consults. - it('a heal:"repair" failure serves; narrates once per generation, twice across a generation bump', async () => { + it('a heal:"repair" failure serves; narrates once per DISTINCT VERDICT, not once per generation bump', async () => { const brain = new Brainy(createTestConfig({ silent: true })) await brain.init() brains.push(brain) @@ -197,12 +197,13 @@ describe('health gate (c) — degraded-but-serving narrates once per generation' const internals = internalsOf(brain) let generation = 1 + let detail = 'counter drift' internals.metadataIndex.healthReport = () => healthReport({ provider: 'vector', serving: true, healthy: false, - invariants: [invariant({ name: 'stale-vector-counter', holds: false, heal: 'repair', detail: 'counter drift' })], + invariants: [invariant({ name: 'stale-vector-counter', holds: false, heal: 'repair', detail })], generation }) @@ -212,11 +213,22 @@ describe('health gate (c) — degraded-but-serving narrates once per generation' await expect(brain.find({ where: { team: 'atlas' } })).resolves.toHaveLength(1) await expect(brain.find({ where: { team: 'atlas' } })).resolves.toHaveLength(1) - expect(countNarrations()).toBe(1) // same generation both times — one narration + expect(countNarrations()).toBe(1) // same verdict both times — one narration + // THE DEDUPE KEY IS THE VERDICT, NOT THE COUNTER.

THE FALSE POSITIVE. stampEntityTree() recorded generationStore.generation() — the ALLOCATED counter, a number a write in flight has claimed and may never commit — while the JSDoc beside it already said the source is the committed generation. Every crash inside a write window therefore produced a spurious verdict at the next open: either 'sourceGeneration N is ahead of the log head N-1' (the allocated generation died with the process) or 'rollup invariant nounCount: stamped X, observed Y' (the recovery fold folded facts the stamp's counts predate). Both told the operator to run repairIndex() — a whole-store recount — for a store that was coherent. Measured before this commit: 4 of 11 SIGKILL cycles on a healthy store raised one of the two. The stamp and the open now both read committedGeneration(), which is what every other open-time watermark in the class already reasons about. THE TERMINAL VERDICT. A stamp still ahead of committed truth after the recovery fold witnesses a generation that is not in the log — the stamp's fsync outlived the tail's, and there is nothing to arrive. That is its own verdict state now ('torn'), never folded in with 'incoherent': the two have opposite cures. A writer open demotes it — the unusable stamped surface is re-derived at the committed generation from the live counters, O(1), straight-line, no loop and no await on external progress, narrated with both count sets, the stamp's path and its committedAt. A read-only open cannot re-stamp, so it says so and names the cure instead of guessing, and still serves. Neither branch waits, and neither locks an owner out of a canonical tree the stamp only describes. Pins: the verifier returns the torn verdict with both generations; a fabricated head-behind-source store narrates precisely, demotes inside a bounded open, serves its rows, and is quiet at the next open (the demotion converges); a read-only open narrates the same verdict and leaves the bytes untouched. --- src/brainy.ts | 121 +++++++++++++++++++- src/db/familyStamp.ts | 32 ++++-- tests/integration/entity-tree-stamp.test.ts | 104 ++++++++++++++++- 3 files changed, 241 insertions(+), 16 deletions(-) diff --git a/src/brainy.ts b/src/brainy.ts index 70d46973..da04577e 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -12497,6 +12497,18 @@ export class Brainy implements BrainyInterface { * healed by `repairIndex()`, whose unconditional recount rebuilds the * rollups from a canonical walk and re-stamps.

It is a WRITER defect, and the reader's refusal was the symptom rather than the cause. A sealed segment declares one contiguous range [firstGeneration, lastGeneration], and every reader treats that range as containment: coveringSegment is an interval test, hasGeneration returns true for anything inside it, and open() seeds committedRanges from it. repackHistory handed fold() a SPARSE batch. Three filters punch holes in its candidate list mid-run — a generation absent from committedRanges never appears, one still in the pending buffer is skipped, one whose tx.json will not read is skipped — and fold() then computed the range from the first and last survivor, claiming every generation in between. The next open merged that mis-declared range back into committedRanges, re-admitting the hole as committed history, so the following auto-compaction pass asked the packed tier for a frame that was never written and failed. Re-merged at every open, which is why it repeated on every run. Confirmed against a forensic fixture: generation directories 1..2503 present except exactly one, 1416; and its fact-log segment already showed the tell — seg-...1410.bfl declaring 1410..1940 (531 generations) while recording 530 facts. Three changes: - repackHistory folds each contiguous RUN as its own segment (`contiguousRuns`), so ranges describe exactly what the segments contain. - fold() REFUSES a non-contiguous batch, naming the gap and its width. The density law is now mechanical, so no future caller can reintroduce it. A refusal loses nothing: the generations stay live and readable. - Stores already carrying the damage heal instead of wedging. A segment whose declared span exceeds its frame count is SPARSE; `actualRanges()` reads the real generation list from its sidecar so open() never re-admits the holes, and readFrame reports such a hole as unpacked with a narration naming the segment, rather than throwing. A DENSE segment missing a frame is still loud damage — that one means the manifest and sidecar disagree. Pins: nine unit cases (refusal and its message, honest ranges for separately folded runs, a reconstructed pre-fix sparse segment serving its real frames while reporting holes as unpacked, holes excluded from actualRanges, and the dense-segment damage path still throwing) plus an end-to-end case that deletes a generation directory and drives the real sequence — ordinary close()-time repacking folds over the hole, then reopen and compact must both complete. Verified red without the fix: the segment declared an 11-generation span while holding 10 frames. --- src/db/generationSegments.ts | 119 +++++++++++++++++++- src/db/generationStore.ts | 66 +++++++++-- tests/integration/history-repacking.test.ts | 102 +++++++++++++++++ tests/unit/db/generation-segments.test.ts | 115 +++++++++++++++++++ 4 files changed, 389 insertions(+), 13 deletions(-) diff --git a/src/db/generationSegments.ts b/src/db/generationSegments.ts index 0c14b60c..91451281 100644 --- a/src/db/generationSegments.ts +++ b/src/db/generationSegments.ts @@ -147,6 +147,60 @@ export class GenerationSegmentStore { return this.coveringSegment(gen) !== null } + /** + * @description True when `meta` declares more generations than it holds + * frames — a segment sealed by a writer that folded across a hole.

THE FALSE POSITIVE. stampEntityTree() recorded generationStore.generation() — the ALLOCATED counter, a number a write in flight has claimed and may never commit — while the JSDoc beside it already said the source is the committed generation. Every crash inside a write window therefore produced a spurious verdict at the next open: either 'sourceGeneration N is ahead of the log head N-1' (the allocated generation died with the process) or 'rollup invariant nounCount: stamped X, observed Y' (the recovery fold folded facts the stamp's counts predate). Both told the operator to run repairIndex() — a whole-store recount — for a store that was coherent. Measured before this commit: 4 of 11 SIGKILL cycles on a healthy store raised one of the two. The stamp and the open now both read committedGeneration(), which is what every other open-time watermark in the class already reasons about. THE TERMINAL VERDICT. A stamp still ahead of committed truth after the recovery fold witnesses a generation that is not in the log — the stamp's fsync outlived the tail's, and there is nothing to arrive. That is its own verdict state now ('torn'), never folded in with 'incoherent': the two have opposite cures. A writer open demotes it — the unusable stamped surface is re-derived at the committed generation from the live counters, O(1), straight-line, no loop and no await on external progress, narrated with both count sets, the stamp's path and its committedAt. A read-only open cannot re-stamp, so it says so and names the cure instead of guessing, and still serves. Neither branch waits, and neither locks an owner out of a canonical tree the stamp only describes. Pins: the verifier returns the torn verdict with both generations; a fabricated head-behind-source store narrates precisely, demotes inside a bounded open, serves its rows, and is quiet at the next open (the demotion converges); a read-only open narrates the same verdict and leaves the bytes untouched.

It is a WRITER defect, and the reader's refusal was the symptom rather than the cause. A sealed segment declares one contiguous range [firstGeneration, lastGeneration], and every reader treats that range as containment: coveringSegment is an interval test, hasGeneration returns true for anything inside it, and open() seeds committedRanges from it. repackHistory handed fold() a SPARSE batch. Three filters punch holes in its candidate list mid-run — a generation absent from committedRanges never appears, one still in the pending buffer is skipped, one whose tx.json will not read is skipped — and fold() then computed the range from the first and last survivor, claiming every generation in between. The next open merged that mis-declared range back into committedRanges, re-admitting the hole as committed history, so the following auto-compaction pass asked the packed tier for a frame that was never written and failed. Re-merged at every open, which is why it repeated on every run. Confirmed against a forensic fixture: generation directories 1..2503 present except exactly one, 1416; and its fact-log segment already showed the tell — seg-...1410.bfl declaring 1410..1940 (531 generations) while recording 530 facts. Three changes: - repackHistory folds each contiguous RUN as its own segment (`contiguousRuns`), so ranges describe exactly what the segments contain. - fold() REFUSES a non-contiguous batch, naming the gap and its width. The density law is now mechanical, so no future caller can reintroduce it. A refusal loses nothing: the generations stay live and readable. - Stores already carrying the damage heal instead of wedging. A segment whose declared span exceeds its frame count is SPARSE; `actualRanges()` reads the real generation list from its sidecar so open() never re-admits the holes, and readFrame reports such a hole as unpacked with a narration naming the segment, rather than throwing. A DENSE segment missing a frame is still loud damage — that one means the manifest and sidecar disagree. Pins: nine unit cases (refusal and its message, honest ranges for separately folded runs, a reconstructed pre-fix sparse segment serving its real frames while reporting holes as unpacked, holes excluded from actualRanges, and the dense-segment damage path still throwing) plus an end-to-end case that deletes a generation directory and drives the real sequence — ordinary close()-time repacking folds over the hole, then reopen and compact must both complete. Verified red without the fix: the segment declared an 11-generation span while holding 10 frames.

The metadata leg sanitized at PLAN time, when the verb was still clean, so the wrap returned the same reference — then the graph op's execute-time endpoint resolution (deliberately deferred for same-batch forward refs) mirrored BigInt sourceInt/targetInt onto the shared object, and the metadata op crossed the seam with them. A strict provider rightly refuses that crossing, so every transact-wrapped edge delete aborted; direct unrelate() resolves ints at build time, before its sanitize, which is why no existing gate saw it. The JSON-safe view now lives in a shared leaf (utils/jsonSafeIndexMetadata) and is applied INSIDE AddToMetadataIndexOperation and RemoveFromMetadataIndexOperation at execute and rollback time — the one place no plan-vs-execute ordering can bypass.

Now an advisory mark records the log's head whenever the pending set drains to empty (and at clean close when empty); recovery scans from the mark + 1. The mark is advisory and monotone-safe: stale-low costs a longer scan, never a marker. The fold itself moves behind the doors as a latched background task — the embed worker starts when it settles, and awaitPendingEmbeds() and close() wait on the latch first, so no caller can observe a half-recovered set. A pending embed's outcome was always eventual; moving its recovery off the foreground changes when the worker starts, never whether a marker is honored. Pinned in tests/integration/pending-embed-low-water.test.ts: the drain writes the mark and the next open scans from mark + 1; a pending embed enqueued after the mark survives an unclean stop; open arms the fold as a background latch the barrier waits on; a clean close writes the mark even without a drain. --- src/brainy.ts | 131 ++++++++++++---- .../pending-embed-low-water.test.ts | 145 ++++++++++++++++++ 2 files changed, 249 insertions(+), 27 deletions(-) create mode 100644 tests/integration/pending-embed-low-water.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 06c947c2..c9f24873 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -1820,31 +1820,31 @@ export class Brainy implements BrainyInterface { // a deferred write's ack and its background embed DELAYED a vector; // this is where it lands. if (!this.isReadOnly) { - try { - await step( - 'bridge-pending-embed-sidecars', - 'migrating any pre-log deferred-embed marker files into the generation log', - () => this.bridgeLegacyPendingEmbedSidecars() - ) - await step( - 'recover-pending-embeds', - 'folding the generation log\'s deferred-embed markers back into the pending set', - () => this.recoverPendingEmbedsFromLog() - ) - if (this._pendingEmbedIds.size > 0) { - prodLog.info( - `[Brainy] ${this._pendingEmbedIds.size} deferred embed(s) pending from a previous ` + - `session — resuming in the background` + // BEHIND THE DOORS (the open pays nothing here): the bridge + the + // recovery fold run as one latched background task; the embed worker + // starts when it settles.

Absent — as it is on this engine's own index — every find is served by the stage doors exactly as before, which is what keeps this engine the ordering oracle for any index that implements one. The contract the door must keep, written where an implementer will read it: identical rows in identical order to what the stage doors would produce; the graph-first law (neighbours are the candidate universe, the filter runs over those ids, orderBy sorts the whole set, the page is cut last); null returned BEFORE any work rather than instead of an answer; and emptyAt naming the stage that produced an empty page, so the serving law is applied to the right index — an empty graph answer is re-verified against the adjacency before it is believed, and a filter-empty is not. Pinned in tests/integration/find-planner-door.test.ts: absent changes nothing; present it is asked first with normalized params, the hidden ids and the graph provider; its page is used and hydrated in its order; a declining door leaves the result identical to the no-door path; and the two emptyAt branches verify the adjacency, or correctly do not. --- src/brainy.ts | 41 ++++++ src/neural/embeddedTypeEmbeddings.ts | 4 +- src/plugin.ts | 46 +++++++ tests/integration/find-planner-door.test.ts | 137 ++++++++++++++++++++ 4 files changed, 226 insertions(+), 2 deletions(-) create mode 100644 tests/integration/find-planner-door.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 696a5f87..464f689b 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -7344,6 +7344,47 @@ export class Brainy implements BrainyInterface { await this.verifyMetadataLive() } + // PLANNED FIND (optional provider door, `MetadataIndexProvider.planFindPage`). + // + // The stage doors below each serve one stage, so a find that consults + // three of them crosses into the index three times and marshals a result + // set at every crossing — a filter matching a hundred thousand rows + // builds a hundred thousand id strings to return a page of twenty-five. + // An index that can decide the stage order itself answers the page in one + // call and materializes ids only for the page. + // + // The hook sits ABOVE the branch selection because the branches are what + // decide stage order per call site; an index that plans has to be asked + // before that choice is made, not inside one of its arms. + // + // Optional and additive: a provider without the door, and any shape the + // door hands back, take exactly the path they always took. `null` is a + // routing decision the door must make BEFORE doing any work — never a + // partial answer.

The semantic leg already walked only the metadata filter's universe. The text leg did not: it ranked the WHOLE store, took the top `limit * 4`, read every one of those rows from canonical, and only then intersected with the filter. On a large store with a selective filter that is hundreds of rows read to return a handful — and a row matching both the query and the filter, but sitting outside the store-wide text prefix, was silently dropped. The same defect `find({ connected })` carried before the graph-first law, one leg over. Both legs now rank ids inside the universe and neither reads canonical. The text leg goes through a new optional `getIdsForTextQueryWithin` door on MetadataIndexProvider — the text twin of `filterIdsWithin`, so a native index can intersect its postings before any string crosses the boundary; the reference index implements it from its own posting-list merge, so the two doors can never disagree, and a provider without it is served by the whole-store answer intersected here. The fusion ranks shells, the page is cut from them, and canonical is read once for exactly that page — with the row rebuilt in full, so a hydrated row is indistinguishable from an eagerly-built one (same flattened fields, same entity, same match visibility, same key order). The eager forms of both legs stay for the search modes whose leg output IS the answer. Measured on the production recall shape (query + type list + `missing` negation + excludeVFS, limit 60) the old order read 241 rows in two batches to return one; the new order reads the page. Pinned in tests/integration/find-hybrid-filter-before-hydrate.test.ts. The oracle there is the pre-change pipeline itself, replayed on the same brain through the same doors: where the filter does not truncate the text leg the answer is identical — rows, order, scores, match visibility and row shape — across hybrid + where, + type list + excludeVFS + a `missing` negation, + connected, with and without offset. Where it does truncate, the correction is held by name: the old order's text leg contributed nothing at all, the new one returns the matching rows and paging reaches every one of them. The cost pins read the engine's own counters: one batchGet of `limit` ids, the whole-store text door never called, and what the text leg marshals bounded by the universe. --- src/brainy.ts | 353 +++++++---- src/plugin.ts | 22 + src/utils/metadataIndex.ts | 66 +- .../find-hybrid-filter-before-hydrate.test.ts | 580 ++++++++++++++++++ 4 files changed, 903 insertions(+), 118 deletions(-) create mode 100644 tests/integration/find-hybrid-filter-before-hydrate.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 4d7596d3..ad8bbf90 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -7651,6 +7651,13 @@ export class Brainy implements BrainyInterface { const searchMode = params.searchMode || 'auto' const limit = params.limit || 10 + // HYDRATE LAST (the hybrid path): its legs and its fusion rank IDS, and + // canonical is read at the two page exits below — never for a row the + // metadata filter is about to discard.

The metadata block ranks the fused candidates and CUTS the page itself — rows [offset, offset+limit) — and then returns early.

MEASURED in production on a 16k-row brain at generation ~478,819: 34-37 seconds inside `generation-store-open-fold` on every open, including the clean one where the answer is always "nothing". The manifest already knows. A sealed segment's `lastGeneration` is written at seal time, and the seal order has been the same since the log was introduced: `rotate()` fsyncs the tail's bytes FIRST ("sealed segments are always fully durable"), builds the entry from the content that fsync covered, and only then flips the manifest — atomically, fsynced, and in the same write re-pointing `tailSegment`, so a sealed file is never appended to again. A crash in that order is safe in the pruning direction: before the manifest write the segment is still the TAIL and is read whole; after it, the entry describes bytes that were already durable. The only later mutation of a sealed segment is open()'s straddle truncation, which removes facts and re-derives the entry from the actual bytes — a recorded bound can drift DOWN with its file, never up. So `lastGeneration = L` proves the file holds no fact above L, and both manifest-direct passes (`peekFactsAbove` and its streaming twin, the recovery fold) now read only the unsealed tail, entries with no numeric `lastGeneration` — legacy or hand-repaired manifests, never prune what you cannot prove — and entries whose recorded maximum is actually above the bound. The open narrates what it read and what it pruned when the log holds more than one segment. Pinned in tests/integration/factlog-open-prune.test.ts, from the log's own counters rather than a clock: a clean reopen over five sealed segments reads exactly the tail (1 of 6) and finds nothing; a real SIGKILLed writer that sealed segments holding facts above the committed pointer has those segments READ, and its peek, its fold stream and its rollback all match the unpruned full scan fact for fact; a manifest entry missing `lastGeneration` is read. --- src/db/factLog.ts | 123 +++++-- tests/integration/factlog-open-prune.test.ts | 360 +++++++++++++++++++ 2 files changed, 462 insertions(+), 21 deletions(-) create mode 100644 tests/integration/factlog-open-prune.test.ts diff --git a/src/db/factLog.ts b/src/db/factLog.ts index ca130454..728be4b1 100644 --- a/src/db/factLog.ts +++ b/src/db/factLog.ts @@ -40,7 +40,10 @@ * The manifest (`_generations/facts/manifest.json`, JSON — forensics stay * terminal-readable) is the single source of truth for the segment SET; * rotation flips it atomically (write-new → fsync → rename) BEFORE the new - * tail's first byte exists, so no segment file is ever unaccounted for. + * tail's first byte exists, so no segment file is ever unaccounted for.

A brain holding even one id that never lands (an embed that keeps failing, a data-less row reaped in memory only and re-folded every open) never drains, so it never writes a mark, so the bound never engaged on exactly the brains whose fold is expensive: `recover-pending-embeds` re-read the WHOLE fact log at every open, on the open's foreground. _system/pending_embeds_checkpoint.json carries the set: { generation, pending, writtenAt } = "as of durable generation G the pending set was exactly this list". Open seeds the set from the list and scans from G + 1, so the fold is O(facts since G) whether or not the set ever drains. Measured on a 301-row brain with one stuck id: 302 facts read before, 0 after; at 601 rows, 602 before, 0 after — same pending set both ways. THE DURABILITY LAW, by construction. A checkpoint at head H taken while the facts up to H are still buffered would be read back after a crash that truncated the tail: an `embed.landed` in a truncated fact would be gone from the log while the checkpoint still recorded its id as landed, and its landing vector went with the fact — a LOST VECTOR. So a capture is refused unless `0 < head <= committed`, the manifest watermark below which FactLog.open() never truncates and which the group-commit flush only advances after fsyncing the log. The (generation, set) pair is taken in one synchronous instant with no await between reading the generations and snapshotting the set. The one remaining asymmetry runs the safe way: an id enqueued in memory whose marker lands at G+1 is captured as pending at G — one idempotent re-embed, never a loss. Written at clean close (inside closeDurableSteps, after the generation store's own close flushed the log and advanced the manifest), at drain-to-empty, and on a cadence of max(64, ceil(|pending| / 64)) transitions while open — an interval that holds the mechanism's amortized cost at <= 64 ids written per transition however large the backlog grows, so the cure cannot reintroduce the defect class it fixes. No timer, no knob. The debt stays armed across attempts the durability law refuses, so a write burst does not skip a checkpoint, it defers it. Degradation is loud and always toward a LONGER scan: a torn checkpoint throws typed on read (the adapter's tmp+rename write means it can never parse into a partial list) and a malformed one is refused whole, both falling back to the low-water mark — still written, still read — and then to generation 1. The fold narrates which bound applied and how many facts it read, on every open, so a bound that stops engaging is visible instead of silent. The worker's orphan reap splits: a row that is GONE clears durably (its tombstone is in the log, or its create never was), while a present-but data-less row keeps clearing in memory only and is carried in the checkpoint list, so the bounded fold and a full fold from generation 1 agree exactly. The crash-recovery contract is unchanged: the fold stays on the open's foreground, markers re-armed when open() returns. --- src/brainy.ts | 416 ++++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 390 insertions(+), 26 deletions(-) diff --git a/src/brainy.ts b/src/brainy.ts index ffc2d5cd..7568a6f3 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -776,6 +776,50 @@ export class Brainy implements BrainyInterface { private _pendingEmbedIds = new Set() private _embedWorkerFlight: Promise | null = null + /** + * Ids cleared from {@link _pendingEmbedIds} with NO durable disarming record + * behind them — today exactly one case: a pending row that still EXISTS but + * carries no embeddable data, which the worker reaps in memory only.

A brain with one permanently-stuck pending id, closed cleanly and reopened, scans ONLY the facts after the checkpoint — read from the fold's own accounting. The same fixture pins the DEFECT it cures: no low-water mark exists on that brain, because it never drained, so nothing could have shortened its fold. A second row proves the bound stays O(delta) across repeated opens while the id is still stuck. 2. A crash matrix in a REAL child process (detached group, SIGKILL, no close), following writer-lock-clean-close's pattern: killed before any checkpoint was written, killed after one with an embed landed and flushed above it, and killed after one with an UN-FLUSHED tail. The invariant in every row is differential — the checkpoint-bounded fold the reopened brain actually ran equals a full fold from generation 1 over the same recovered log. 3. A torn checkpoint (bytes that are neither gzip nor JSON) falls back loudly — the adapter's torn-record gauge and production error, plus the fold's own narration of the bound it used — and still recovers the marker from the log. A well-formed but shape-invalid checkpoint is refused WHOLE: trusting its generation while ignoring its list is the one shape that could bound a scan behind a set that was never recovered. 4. The existing low-water pins pass unchanged — the mark is still written and still read, now as the fallback bound beneath the checkpoint. --- .../pending-embed-checkpoint.test.ts | 547 ++++++++++++++++++ 1 file changed, 547 insertions(+) create mode 100644 tests/integration/pending-embed-checkpoint.test.ts diff --git a/tests/integration/pending-embed-checkpoint.test.ts b/tests/integration/pending-embed-checkpoint.test.ts new file mode 100644 index 00000000..1cf3ec2c --- /dev/null +++ b/tests/integration/pending-embed-checkpoint.test.ts @@ -0,0 +1,547 @@ +/** + * @module tests/integration/pending-embed-checkpoint + * @description THE PENDING-EMBED CHECKPOINT — the bound that engages on the + * brains that need it. + * + * 10.4.9 bounded the open-path `recover-pending-embeds` fold with a LOW-WATER + * MARK: the log head at which the pending set last drained to EMPTY.

Every path-scoped VFS search threw on this engine line; the two pins in tests/vfs/vfs.unit.test.ts that exercise it have been red since the operator law landed. The scope is now a half-open range over `metadata.path`: `[dir + '/', dir + '0')`. Every descendant path begins with `dir + '/'`, and '0' is the code point directly after '/', so membership in the range is EXACTLY "carries that prefix" — and because the bounds differ at one ASCII position the answer is identical under code-unit and code-point collation. Siblings fall out correctly for the same reason: `/scope-sibling/x` sorts below the lower bound and `/scope0` sits at the open upper bound. `recursive: false` narrows to the directory's own identity instead — `parent`, an indexed equality. The root adds no clause, because every VFS entity is under it. `path` is the VFS's truth (write and rename maintain it; the `Contains` edges are a projection of it), it is already indexed on every VFS entity, and `explain()` reports the range as `column-store` — "O(log n) binary search + roaring bitmap". So the scope narrows the search before it runs: no tree walk, no migration, no backfill, and nothing fetched that the scope then discards. Two other shapes were considered and rejected. A graph-scoped walk over `Contains` reads the projection rather than the truth and costs O(subtree) adjacency lookups per search, with the subtree's height as an unknown `depth`. An indexed `ancestors: string[]` field cannot be implemented honestly today: the index extractor skips arrays longer than ten elements, so a path more than ten levels deep would silently drop out of every scoped search — and it needs a backfill besides. Pinned in tests/vfs/vfs-search-path-scope.test.ts (all eight red before this change): descendants at three depths and never a sibling, including the `/scope-sibling` and `/scope0` prefix traps; a trailing or doubled slash names the same scope; the root scope equals the unscoped search; `recursive: false` is the immediate children and refuses a missing directory by name; every operator the search emits is ANSWERED by the index's own door rather than refused; the id universe the index resolves for the search is already the scope; and the range agrees with walking the tree. --- src/vfs/VirtualFileSystem.ts | 73 ++++++++++- tests/vfs/vfs-search-path-scope.test.ts | 165 ++++++++++++++++++++++++ 2 files changed, 233 insertions(+), 5 deletions(-) create mode 100644 tests/vfs/vfs-search-path-scope.test.ts diff --git a/src/vfs/VirtualFileSystem.ts b/src/vfs/VirtualFileSystem.ts index 1a4b9fa5..bccd6fea 100644 --- a/src/vfs/VirtualFileSystem.ts +++ b/src/vfs/VirtualFileSystem.ts @@ -1572,7 +1572,19 @@ export class VirtualFileSystem implements IVirtualFileSystem { // ============= Semantic Operations ============= /** - * Search files with natural language + * Search files with natural language. + * + * `options.path` scopes the search to a directory: its whole subtree by + * default, its immediate children when `recursive` is `false`.

A host that owns its own shutdown — one SIGTERM listener calling close() on every pooled store — ran head-on into the engine's own signal handler, which iterated every live instance, flushed its components in parallel, and released its writer lock in its own finally. Two teardowns of the same brain at the same moment: "Shutdown signal received - flushing pending data...", 148s of silence, "Flushed successfully (1 instance)", and the host's pool close of that same store returning 1s later — 149s against 24s for the six stores with no engine work in flight. The same race reproduced locally as "Failed to flush one Brainy instance on shutdown: Writer fence lost … the lock file is gone": the handler observing a lock the close it was racing had already released. Three changes, one law — a brain's teardown belongs to whoever started it. 1. close() is idempotent and re-entrant. The first call stores its promise synchronously in _closeInFlight and every later or concurrent caller gets that same promise back; the teardown runs once. close() is no longer async so the promise is shared by identity, not just outcome. The state is observable: isClosing (begun) and isClosed (finished). 2. The signal handler defers one macrotask, then per instance either steps aside (a close has begun or finished — its owner owns the flush, the markers and the lock) or awaits instance.close(): the same settle/flush/attest/ marker/lock path any caller gets. Its old parallel per-component flush and separate lock release are gone; the three laws that block carried are each satisfied by close(), verified line by line and recorded in the new comment. Per-instance isolation stays here, in the loop's try/catch. Sole-owner exit now reads the listener count WHEN THE SIGNAL ARRIVES. Asking afterwards reads a process that has already torn itself down — closing the last brain deregisters the engine's own listeners, so a host's single remaining listener would look like "<= 1" and be force-exited out of its own graceful shutdown. 3. Flush is single-flight with a queue one deep. It did not coalesce: the cadence's guard covered only the flushes the cadence started, so a cross-process flush request or an application flush() overlapped it freely — production showed two "Flushing Brainy indexes…" runs 3s apart, walls growing 295ms to 4.9s. The gate now lives in flush() itself and covers every caller: run, or join the ONE queued follow-up. A follow-up rather than joining the running flush, because a caller flushes to make ITS writes durable and those may have landed after the running flush read its state; it costs nothing when there is nothing new. close() drains that chain too. The idle law is untouched: a clean brain's flush still returns immediately, and an idle brain still flushes zero times. --- src/brainy.ts | 364 ++++++++++++++++++++++++++++++++++++-------------- 1 file changed, 267 insertions(+), 97 deletions(-) diff --git a/src/brainy.ts b/src/brainy.ts index 7568a6f3..39b604ad 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -767,6 +767,34 @@ export class Brainy implements BrainyInterface { private _persistIdleTimer: ReturnType | null = null private _persistBackgroundFlight: Promise | null = null + /** + * FLUSH IS SINGLE-FLIGHT, AND THE QUEUE IS ONE DEEP. `_flushInFlight` is the + * flush body actually running; `_flushFollowUp` is the AT MOST ONE flush + * queued behind it.

The release count is the discriminating assertion — against the old handler it reads {a: 2, b: 2}, one release from the owner's close and one from the handler's own finally. (b) No host owner: the engine's handler closes every instance by the same path — one close each, markers written, clean exit, clean reopen. (c) Two concurrent close() callers share one promise (by identity) and one execution; a third call after they settle runs nothing. (d) Eight kicks during a running flush — five through the cadence door, three direct — arm exactly ONE follow-up: two flush bodies total, and the concurrency high-water mark stays at 1. The counts come out of the child through a file written synchronously on the way out: the engine calls process.exit(0) when it is the sole shutdown owner, and a console.log to a pipe can be dropped by that exit. --- .../integration/shutdown-single-owner.test.ts | 405 ++++++++++++++++++ 1 file changed, 405 insertions(+) create mode 100644 tests/integration/shutdown-single-owner.test.ts diff --git a/tests/integration/shutdown-single-owner.test.ts b/tests/integration/shutdown-single-owner.test.ts new file mode 100644 index 00000000..d3c02f99 --- /dev/null +++ b/tests/integration/shutdown-single-owner.test.ts @@ -0,0 +1,405 @@ +/** + * @module tests/integration/shutdown-single-owner + * @description ONE SHUTDOWN, ONE OWNER. + * + * MEASURED IN PRODUCTION.

That waiter is settled ONLY by resolving the very promise the leader is being awaited through, so the moment anything inside a flush body awaits flush(), the promise graph closes on itself and nobody resolves — an unbounded hang, not a slow flush, presenting exactly like a bulk write timing out. No current call site awaits a flush from inside one, so this is a latent cycle rather than an observed one; the gate should not depend on that staying true. The queue is now a bare deferred. The leader's finally opens the gate and PROMOTES the waiter to a new leader, settling the deferred from that run; the finally returns nothing, so the leader never awaits its own follower. Every exit runs the same promotion — the leader resolving, the leader rejecting, the promoted run rejecting — so a queued caller is settled exactly once on every path, and a synchronous failure starting the promoted run is reported to the waiter instead of thrown into the leader's finally. close() drains both handles. tests/unit/brainy/flush-single-flight.test.ts pins the invariant on each path that must settle a waiter: many callers during one flush all resolve within a bound (one body, one follow-up, peak concurrency 1); a REJECTING leader still runs and settles the queued waiter; a rejecting follow-up settles its waiter and leaves the gate open; and the leader returns without waiting for a deliberately slower follower. --- src/brainy.ts | 80 ++++++-- .../integration/shutdown-single-owner.test.ts | 6 +- tests/unit/brainy/flush-single-flight.test.ts | 175 ++++++++++++++++++ 3 files changed, 243 insertions(+), 18 deletions(-) create mode 100644 tests/unit/brainy/flush-single-flight.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 02f2ca3d..81250144 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -785,9 +785,25 @@ export class Brainy implements BrainyInterface { * "Flushing Brainy indexes and caches to disk..." runs overlapping 3s * apart on one brain, their walls growing 295ms → 4.9s as they contended * for the same providers. + * + * THE WAITER IS SETTLED BY THE MACHINE, NEVER BY A PROMISE CHAIN.

-0700 Subject: [PATCH 198/229] =?UTF-8?q?fix(shutdown):=20beforeExit=20never=20c?= =?UTF-8?q?loses=20a=20live=20brain=20=E2=80=94=20a=20drained=20event=20lo?= =?UTF-8?q?op=20is=20not=20a=20shutdown?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 10.4.11 gave shutdown one owner and one path — close() — and wired all three process listeners to it. That is right for SIGTERM and SIGINT. It is wrong for 'beforeExit', which Node emits whenever the event loop has no REF'd work left: not when the process is ending, and with no signal involved. A healthy script reaches that state routinely, because this engine unref's its idle and cadence timers ("an idle brain costs nothing"), so a script awaiting anything those timers drive is, for that instant, a process with no ref'd work and an open brain. MEASURED on the 11.1 rehearsal lane against a copy of a real store: after the heal phase the log printed "Shutdown signal received - flushing pending data..." and "Flushed successfully (1 instance)" with no signal ever sent, and the script's very next add() threw "Brainy instance is not initialized: it was closed via close(). Create a new instance." The engine had closed a live brain out from under a running script. The beforeExit listener now runs its own pass, which closes nothing, deregisters nothing, releases no writer lock, and never force-exits: it runs flush() — the engine's own non-closing durability door — on each live brain and leaves every one of them open and usable. flush() persists derived state only (count ledger, projections, generation counter, aggregation, entity-tree stamp); the clean-shutdown marker is generationStore.close()'s word about itself, reached only from close(). Running it concurrently with live writes is the engine's ordinary steady state — noteWriteForPersistence() kicks the same call off an unref'd timer on every busy brain — and it is single-flight, so there is no new race. A throw is reported per instance and the pass continues: canonical data is durable at ack via the fact log, so a failed derived-state flush costs the next open a rebuild, never the caller their brain. The listener is no longer self-deregistered. It does not need to be: a flush on a clean brain schedules no I/O, so the emit after it does no event-loop work and the process exits on its own. A one-shot listener spent on a spurious mid-script drain would leave the genuine end-of-script drain with nothing. The drained-loop notice is printed once per registration cycle, because a console.log to a pipe is itself event-loop work. exitIfSoleShutdownOwner() stays on the signal path alone, and its contract now says so: beforeExit suppresses no default behaviour, so exiting from it would end a live script at code 0 mid-work. THE NAMED TRADE: a script that opens a brain and never closes it now exits with its writer lock still on disk and no clean-shutdown marker, so its next open overwrites a stale lock and folds the log. That is the honest cost of never closing, and the narration names the cure. Closing a live brain to avoid it was the worse half of the trade. Pins: tests/integration/beforeexit-never-closes.test.ts — a script that drains the loop with a brain open keeps a working brain (add + find succeed, the lock is still held, the process still exits 0), the pass flushed and wrote neither of close()'s markers, and repeated drains are idempotent. Both cases fail on 10.4.11's handler with the exact production shape ("add() after the drain failed", "pass 1 closed the brain"). Re-run green: shutdown-single-owner, writer-lock-clean-close, idle-costs-nothing, shutdown-hooks-lifecycle. docs/concepts/multi-process.md no longer claims beforeExit releases the lock. --- docs/concepts/multi-process.md | 11 +- src/brainy.ts | 147 ++++++++- .../beforeexit-never-closes.test.ts | 309 ++++++++++++++++++ 3 files changed, 450 insertions(+), 17 deletions(-) create mode 100644 tests/integration/beforeexit-never-closes.test.ts diff --git a/docs/concepts/multi-process.md b/docs/concepts/multi-process.md index 8fda315f..d698eee8 100644 --- a/docs/concepts/multi-process.md +++ b/docs/concepts/multi-process.md @@ -95,8 +95,15 @@ The heartbeat interval rewrites the lock file every 10 seconds.

the column store serves it; the canonical record is opened only for fields the index cannot supply. The provider grows an optional getScalarsForIds(ids, fields) door, batched: it walks each column ONCE and picks out every requested id, rather than re-walking per row. The column store grows the primitive that was missing — valuesForIds — because every other read door there answers which entities have a value, and a projection asks the opposite. It reads the COLUMN store, never the sparse index: the column keeps raw values, the sparse index keeps a bucketed form built for range queries, and a projection served from the latter would return a value that differs from the record's. A field the column cannot serve is omitted rather than approximated — omission costs a read, a wrong value is a wrong answer nobody can see. Two laws the pins hold: fields absent is byte-identical to today, and a missing field is simply absent rather than an error — so this path deliberately avoids the strict address resolver, whose UnresolvableFieldError is right for orderBy and wrong here. related() takes no fields: a Relation carries from/to as ids and hydrates no record, so the param would be decorative. --- src/brainy.ts | 208 +++++++++++++++- src/indexes/columnStore/ColumnStore.ts | 52 ++++ src/neural/embeddedPatterns.ts | 2 +- src/plugin.ts | 39 +++ src/types/brainy.types.ts | 60 +++++ src/utils/metadataIndex.ts | 61 +++++ .../find-fields-projection.test.ts | 224 ++++++++++++++++++ 7 files changed, 639 insertions(+), 7 deletions(-) create mode 100644 tests/integration/find-fields-projection.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 3fe57053..18c46d48 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -4193,6 +4193,16 @@ export class Brainy implements BrainyInterface { } // Route to metadata-only or full entity based on options + // A PROJECTED get goes through the same seam every list page uses, so a + // detail read of two scalars costs an index read rather than a record read. + // It is checked before `includeVectors` because the two are incompatible by + // construction: a projection returns the named fields, and a vector is not + // one of them unless it was named. + if (options?.fields !== undefined && options.fields.length > 0) { + const page = await this.hydratePage([id], options.fields) + return page.get(id) ?? null + } + const includeVectors = options?.includeVectors ?? false // Default: metadata-only (fast) if (includeVectors) { @@ -4239,6 +4249,170 @@ export class Brainy implements BrainyInterface { * const children = childIds.map(id => childrenMap.get(id)).filter(Boolean) * ``` */ + /** + * **The projection seam** — hydrate a page of ids under an optional `fields` + * projection, opening the canonical record only when the index cannot serve + * what was asked for. + * + * Without a projection this is exactly `batchGet`, byte for byte: the whole + * point is that `fields` absent changes nothing. + * + * With one, the order is: ask the index for the named scalars in a single + * batched door; see which requested fields it actually served; and read + * records ONLY if something is still missing — and only to fill those fields. + * A page whose every requested field is index-served performs zero canonical + * reads, which is the whole reason the door exists. + * + * `guardFields` are fetched ALONGSIDE the projection and trimmed off before + * the caller sees them. find()'s index-integrity guard re-validates every row + * against its own predicate, and it reads the entity to do so — so a row + * projected down to `title` would fail a `where: { kind }` it genuinely + * matches, and the whole page would vanish.

charset=UTF-8 Content-Transfer-Encoding: 8bit `getIdsForRange` routes two ways. The column store compares RAW values and is correct. The legacy sparse chunk index — the pre-7.20.0 fallback, still read for workspaces that have not been rebuilt — compared normalizeValue() output, and normalizeValue carries an escape hatch that destroys order on purpose: a string over 100 characters becomes a short hash so it can serve as a filesystem-safe key. Ordering hashes ranks rows by digest. Two shapes, both silent: (a) A LONG BOUND against ordinary values. `{ gte: }` collapsed the BOUND to `__HASH_…`, whose leading underscores sort below every letter — so a bound that should have excluded everything matched the entire field instead. Measured on the fixture here: 3 of 3 rows returned where 0 is correct. This shape reaches a caller who never stored a long value at all. (b) LONG VALUES in the index. The field was persisted hashed, so its order is not recoverable from this index. The old code compared the digests anyway and returned a subset chosen by hash — 1 of 3 rows, the wrong one. Bounds are now normalized WITHOUT the hash escape hatch, so a long bound stays comparable and (a) is simply fixed. Where the persisted KEY is a hash the order does not exist to be computed, and the query throws a typed BrainyError('INVALID_QUERY') naming the field and the cure. The refusal is checked before chunk SELECTION as well as during the scan: selection orders the bounds against each chunk's zone map, and its failure mode is an empty answer — the quietest wrong answer of all. Equality on a hashed field is untouched; only ordering is refused. KNOWN, NAMED DIVERGENCE, recorded in the doc comment rather than papered over: the persisted keys are also lower-cased and trimmed, so this path's string ranges are case-INSENSITIVE where the column store's are not. The raw values are not in the index to compare — that is a property of the bytes a pre-7.20.0 engine wrote, and it ends when the column store adopts the field. The pin builds a genuine legacy index through the same ChunkManager / SparseIndex doors that engine wrote through, into a field the column store does not serve. The chunk write path was removed in 11be039, so that is the only way to build the shape this read path exists for. --- src/utils/metadataIndex.ts | 118 +++++++- ...tadataIndex-sparse-range-collation.test.ts | 258 ++++++++++++++++++ 2 files changed, 366 insertions(+), 10 deletions(-) create mode 100644 tests/unit/utils/metadataIndex-sparse-range-collation.test.ts diff --git a/src/utils/metadataIndex.ts b/src/utils/metadataIndex.ts index d07fa8d7..83d37379 100644 --- a/src/utils/metadataIndex.ts +++ b/src/utils/metadataIndex.ts @@ -961,9 +961,41 @@ export class MetadataIndexManager implements MetadataIndexProvider { } /** - * Get IDs for a range using chunked sparse index with zone maps and roaring bitmaps - * Now fully lazy-loaded via UnifiedCache (no local sparseIndices Map) - * Normalize min/max for timestamp bucketing before comparison + * Get IDs for a range using the legacy chunked sparse index (zone maps + + * roaring bitmaps).

Snelling Date: Wed, 2 Sep 2026 13:43:14 -0700 Subject: [PATCH 207/229] fix(metadata): the indexable-array bound is a named law with a refusal, not a silent skip MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An array-valued metadata field indexes one posting per element, so the index has always carried a ceiling. It was 10, and it was applied by a bare `continue` deep inside field extraction: if (Array.isArray(value) && value.length > 10) continue A row whose `tags` array held ELEVEN entries therefore had that field skipped entirely — no posting, no error, no warning. The row then failed to match every filtered search on `tags`, including a query for a tag it demonstrably held, and the caller had no way to tell that from "no row matches". Eleven tags is not an exotic shape; the eleventh tag made the row invisible. Measured on the pin here: the where-clause returns [] on the base for all eleven values. The ceiling is not the defect. The silence was. THE LAW. MAX_INDEXED_ARRAY_LENGTH = 64, hardcoded (the zero-config law: no knob), sitting far above every legitimate multi-value field — tags, authors, categories, labels, participants — and far below any real embedding width, so the two populations do not overlap and nobody has to tune it. Arrays of scalars index in full up to the bound. Above it the WRITE IS REFUSED by name: MetadataArrayTooLargeError carries the field (its full dotted address), the length and the bound, and names the three cures. It fires at all four write doors — add, update, relate, updateRelation — beside the existing forged-system- key rejection, and walks nested bags because a nested field indexes under its dotted address exactly like a top-level one. THE ONE PLACE THE BOUND STILL SKIPS is a row already on disk, written by an older engine under the old rule and read back by a rebuild, a catch-up fold or a remove. extractIndexableFields serves all three, so refusing there would make an existing store un-rebuildable — the row is admitted and the skipped field is NARRATED with the field, the length and the bound. Never silent, either way. tests/integration/metadata-vector-exclusion.test.ts carried the old law as a green assertion ("should skip indexing large arrays (>10 elements)"). It is rewritten to the new one, plus a case proving a 64-element array indexes in full and its eleventh element is searchable. The original bug that suite exists for — per-dimension numeric field explosion — is still asserted on both paths. --- src/errors/brainyError.ts | 65 +++++ src/index.ts | 2 +- src/utils/metadataIndex.ts | 45 +++- src/utils/paramValidation.ts | 49 ++++ .../metadata-vector-exclusion.test.ts | 58 +++-- .../utils/metadataIndex-array-bound.test.ts | 242 ++++++++++++++++++ 6 files changed, 436 insertions(+), 25 deletions(-) create mode 100644 tests/unit/utils/metadataIndex-array-bound.test.ts diff --git a/src/errors/brainyError.ts b/src/errors/brainyError.ts index a58236e3..4301d3f7 100644 --- a/src/errors/brainyError.ts +++ b/src/errors/brainyError.ts @@ -405,3 +405,68 @@ export class MigrationInProgressError extends BrainyError { } } } + +/** + * THE INDEXABLE-ARRAY BOUND.

[PATCH 208/229] fix(close): a read-only brain writes nothing under `_system/` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `readonly-close-no-marker` closed the clean-shutdown-marker half of this law and named the rest as a known residual. This is that residual, closed. MEASURED on the base: a read-only open → read → close rewrote FOUR files — `_system/__metadata_field_registry__.json.gz`, `type-statistics.json.gz`, `subtype-statistics.json.gz` and `verb-subtype-statistics.json.gz`. An IDLE reader that only opened and closed rewrote all four as well. The cause was not the closes the marker fix guarded. It was Phase 1 of closeDurableSteps, where every component flush ran unconditionally. A flush is a write by definition: MetadataIndexManager#flush() saves the field registry "even with no dirty fields" (its own comment), and the storage adapter's count flush re-stamps the three statistics files. A session that committed nothing re-stamped all four. Phase 2's closes were ungated too — the graph index's close drains both LSM MemTables to SSTables and stamps its watermark, and the optional vector/metadata `close` hooks (unimplemented in the reference engine, filled in by a native provider) persist buffered state. Every one of those calls now carries the same `!isReadOnly` guard the generation store already had. A reader still RELEASES what it holds, so Phase 2 is a branch rather than a skip: GraphAdjacencyIndex gains `stopBackgroundFlush()`, the non-writing half of its close, which clears the auto-flush interval that would otherwise outlive the session. `close()` now calls it too, so there is one place that owns the timer. Why this matters beyond tidiness: `_system/` is where a store keeps its evidence about itself — what the writer committed, what the projections have seen. A reader that rewrites any of it vouches for a state it only observed, and on shared or snapshot storage it mutates bytes another process owns. The pin hashes every file under `_system/` (and, in one case, the whole store) across a reader's open → read → close, names the four paths that used to move so a regression says which subsystem did it, and asserts the asymmetry holds in the other direction — a WRITER's close still persists. --- src/brainy.ts | 43 ++- src/graph/graphAdjacencyIndex.ts | 22 +- .../readonly-close-no-marker.test.ts | 12 +- .../readonly-close-writes-nothing.test.ts | 261 ++++++++++++++++++ 4 files changed, 322 insertions(+), 16 deletions(-) create mode 100644 tests/integration/readonly-close-writes-nothing.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index a97bdde2..5fd6c627 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -20834,34 +20834,45 @@ export class Brainy implements BrainyInterface { // Phase 1: Flush ALL components in parallel to persist buffered data // This is critical when cor native providers buffer data in Rust memory + // + // READ-ONLY GUARD, applied to EVERY flush here.

On the next regeneration both would have been emitted as contract doors, obliging every engine implementing contract 1 to provide the flush gate's own bookkeeping. A door is a promise; these are internals. Converted to ECMAScript-private (`#`), which keeps them off the prototype entirely, and the reason is recorded on both so the next internal is not written as `private` by habit. `_runFlush` — the flush body itself — was already safe by the emitter's underscore rule. Verified: `npm run build && node scripts/emit-contract-manifest.mjs` then `--check` green at 302 doors, with neither name present. TWO MANIFEST NOTES, both deliberate and neither hidden: 1. The regenerated manifest gains `MetadataArrayTooLargeError`. The emitter lists every `*Error` export from brainyError.js, and that class is the write door's refusal for an over-bound metadata array (this branch's array-bound commit). It is a real addition to the engine's error surface, so the manifest is right to carry it — flagged here because it is a contract-surface change that the cut should accept knowingly, not a side effect that slipped in. 2. `armIdleFlushTimer` and `kickBackgroundFlush` are TypeScript `private` in src and ARE already in the committed manifest as doors — the same leak, one release older. They are left exactly as they are: removing a name the manifest already publishes is a contract deletion, not a hygiene fix, and it belongs to whoever owns contract 1 rather than to this branch. --- docs/api-contract.json | 1 + src/brainy.ts | 24 +++++++++++++++++------- 2 files changed, 18 insertions(+), 7 deletions(-) diff --git a/docs/api-contract.json b/docs/api-contract.json index 12cb37c8..c4f4e056 100644 --- a/docs/api-contract.json +++ b/docs/api-contract.json @@ -1507,6 +1507,7 @@ "BrainyError", "DerivedArtifactMissingError", "GraphIndexNotReadyError", + "MetadataArrayTooLargeError", "MetadataIndexNotReadyError", "MigrationInProgressError", "ProtectedArtifactError", diff --git a/src/brainy.ts b/src/brainy.ts index 5fd6c627..15f51ef9 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -13342,25 +13342,33 @@ export class Brainy implements BrainyInterface { } return this._flushQueued } - return this.startFlushLeader() + return this.#startFlushLeader() } /** * @description Run one flush body as the leader and install it as - * `_flushInFlight`.

-0700 Subject: [PATCH 212/229] ci(release): publish the wall entry to the shared releases repo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The rail used to write releases/open-brainy.json (and, before that, also carried the product engine's releases/brainy.json) in this repo. It now clones (or refreshes a cached clone of) soulcraftlabs/releases on The Source, prepends the derived entry to open-brainy.json there (replacing any entry for the same version so a re-run is idempotent), and pushes main directly. Any failure — clone, shape validation, commit, or a rejected push — exits non-zero naming the cure; nothing is ever skipped. Both wall files are gone from this repo — the shared repo is the one home HQ reads. --dry-run derives and prints the entry without touching any clone or remote. Tests point --remote/--cache-dir at a throwaway local bare repo and cache dir, never the real ones. --- releases/brainy.json | 76 -------- releases/open-brainy.json | 136 ------------- scripts/release.sh | 13 +- scripts/wall-entry.mjs | 253 ++++++++++++++++++------ tests/unit/release/wall-entry.test.ts | 271 +++++++++++++++++++++----- 5 files changed, 423 insertions(+), 326 deletions(-) delete mode 100644 releases/brainy.json delete mode 100644 releases/open-brainy.json diff --git a/releases/brainy.json b/releases/brainy.json deleted file mode 100644 index 8f61c7f2..00000000 --- a/releases/brainy.json +++ /dev/null @@ -1,76 +0,0 @@ -{ - "product": "brainy", - "entries": [ - { - "version": "11.0.5", - "date": "2026-09-02", - "headline": "Graph-first finds in production, and opens that stop rescanning history", - "items": [ - "find({ connected, where }) now walks the neighbours first and filters only those rows through a native door — correct at every page and O(neighbours), never the whole store.", - "related() with a list of verb types returns every requested kind (a fast path had silently kept only the first).", - "Deferred-embedding recovery resumes from a low-water mark instead of rescanning the whole generation log at every open — measured at two minutes on a large brain, now milliseconds." - ], - "url": null, - "thumb": null - }, - { - "version": "11.0.4", - "date": "2026-09-01", - "headline": "Closes in milliseconds, index rebuilds without the disk-sync storm", - "items": [ - "close() no longer pays deferred compaction or waits out an in-flight rebuild — measured 8 ms against the 4-minute closes it replaces; deferred work resumes at the next open, in the background.", - "The metadata index's rebuild syncs to disk per shard instead of per row, and the durability point moved to the publish step — the same guarantee, a fraction of the disk traffic.", - "A new native filter door evaluates queries over exactly the candidate rows a graph walk found, never the whole store." - ], - "url": null, - "thumb": null - }, - { - "version": "11.0.3", - "date": "2026-09-01", - "headline": "The embedding upgrade ceremony runs on every brain", - "items": [ - "A brain opened through the standard plugin now carries its embedding-model identity, so the full-precision upgrade ceremony can run on it.", - "A one-fix release; nothing else changed." - ], - "url": null, - "thumb": null - }, - { - "version": "11.0.2", - "date": "2026-08-31", - "headline": "One embedding quality everywhere, 3–4× faster imports", - "items": [ - "Every runtime embeds with the same full-precision model — search quality no longer depends on where you run.", - "Bulk embedding measured 3.1–4.2× faster, and an online re-embed ceremony upgrades existing stores without downtime.", - "The engine's change feed is documented, with the SSE/WebSocket fan-out pattern for realtime surfaces." - ], - "url": null, - "thumb": null - }, - { - "version": "11.0.1", - "date": "2026-08-31", - "headline": "Deletes inside transactions are safe", - "items": [ - "Deleting relations inside a transact() no longer corrupts index bookkeeping.", - "A store that deletes its last relation keeps serving instead of refusing." - ], - "url": null, - "thumb": null - }, - { - "version": "11.0.0", - "date": "2026-08-28", - "headline": "One install, one engine — Brainy", - "items": [ - "The former two-package pair is one package: the native engine under the familiar API.

The indexable-array bound refuses that shape at the write door now — an array field mints one posting per element, so an unbounded array is an unbounded write — and the three cases were failing on the refusal they should have been pinning. Each is rewritten to the law that replaced it, in two halves: - a large SCALAR payload still round-trips whole through the door: a 10,000-character string, 100 sibling fields, a ten-deep nest walked to the bottom, and an array sitting exactly ON the bound, checked first element to last; - an array one element OVER the bound refuses with MetadataArrayTooLargeError carrying the field, the length and the bound, on the error object AND in the message. update()'s refusal additionally proves the row is unchanged, and relate()'s that no relation was written — refused means not written, not written-then-skipped. Every length is derived from the imported MAX_INDEXED_ARRAY_LENGTH; none is typed as a number. That is what made the old cases fragile: 100 read as "over the bound" and 1000 as "large", and both meanings changed under them when the constant moved.

The case now runs the same query without the vector leg first, as a control, and reports both counts: both short means the neighbour set or the filter, only the vector leg short means the walk — which matters here because every row in this corpus carries an IDENTICAL vector, so the walk is ranking an exact tie and a tie has no defined order to return 5 of.

It could not say WHICH, and the advice it gave — read the 'stdout | > ' prefix — cannot work here: vitest tags a stdout block with the test that is RUNNING, and these lines are captured by this test's own console hook anyway. Teeing them through would only ever print this test's name. The call stack does name the driver, so it is captured beside each line and the first one is reported: `kickBackgroundFlush('idle')` under `armIdleFlushTimer` is some brain's cadence timer, the deferred-embed worker's commit path is a brain still landing vectors, and a bare `flush()` is an explicit caller. Why that distinction settles it. A flush only narrates PAST the dirty gate, and `_dirtySinceLastFlush` is set in exactly three places — `noteWriteForPersistence()` (both commit paths, and the deferred-embed worker lands its vectors through the single-op one), `clear()`, and `repairIndex()`. So a narrating flush is a flush whose brain really did commit a write; "0 ms" is the flush being cheap, not the flush being empty. That reading rules OUT the re-arming-follow-up theory: the queued follow-up is armed only by a concurrent flush() caller, cleared before promotion, and a promoted run over a clean brain returns at the dirty gate without touching a provider or printing a line. Context the message now carries: the suite runs every file in ONE process, and a create-versus-close scan puts 67 test files above the line — more brains made than closed.

Every later value of another kind was coerced to that type, and when coercion failed — `Number('electronics')` is NaN — the value was dropped from the index with no error at all. The row stayed readable by id and by vector search and vanished only from equality filters on that one field, which is what made it so quiet: writing `category: 'electronics'` rows and then `category: 5` rows left `where { category: 5 }` returning nothing, while the same rows in a numbers-only corpus answered correctly. The column store now keeps one posting column per (field, kind), where a kind is a JavaScript typeof class. The first kind a field sees keeps the historical `_column_index//` layout, so a single-kind field is byte-identical to what earlier versions wrote and an index written before this opens unchanged; each later kind takes its own column at `_column_index//k//`. Equality reads the column matching the query value's own kind, so `{c: 5}` and `{c: '5'}` match different rows and neither is coerced into the other. Ranges route by the kind of their bounds, and an unbounded range — the "has any value" probe behind `exists` — reads every kind. A mixed field orders by kind first, then by value, because a number and a string have no order between them. A value that cannot be encoded for the column its own kind selected now raises instead of being skipped: that path is unreachable by construction, and if it is ever reached it is the silent drop this change exists to end. Two neighbours fell out of the same routing. A boolean query value is now encoded to the 1/0 the column stores, so boolean equality matches at all. And an integer column widens to f64 the first time a non-integer arrives, so 4.5 is stored as itself rather than rounded to 5 and answering the wrong query. Field type inference reports every kind a field holds beside its dominant reading, rather than leaving callers to treat one type as the whole answer. Pins: mixed-kind equality in both write orders, `5` vs `'5'`, booleans mixed in, a numeric range over a mixed field's numbers, close/reopen keeping every typed posting, and an index in the pre-existing on-disk shape still reading. `tests/critical-neural-validation.test.ts` — which writes `category` as strings in one test and as numbers in another against one shared brain — passes whole for the first time.
