From 300d9f2a16944fe49cbece344df48bc97c4bbfed Mon Sep 17 00:00:00 2001 From: David Snelling Date: Sun, 19 Jul 2026 12:04:39 -0700 Subject: [PATCH 001/175] =?UTF-8?q?feat:=20flush()=20never=20compacts=20?= =?UTF-8?q?=E2=80=94=20history=20maintenance=20moves=20to=20close()=20with?= =?UTF-8?q?=20bounded=20passes?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit flush() is durability work: it must cost what the current window's deltas cost, never what the history backlog costs. Under adaptive retention the byte budget derives from free memory, so bulk-load pressure shrank the budget exactly at peak write volume and flush paid actual reclaim inline — a production deployment measured single writes blocked 25-191s behind reclaim-on-flush. - flush() no longer calls autoCompactHistory(); close() is THE auto-compaction site (already ran there; now alone). - Every auto pass is time-bounded (CLOSE_COMPACTION_BUDGET_MS = 5s): reclamation is oldest-first, so an early stop is a consistent prefix and the next pass resumes. Explicit compactHistory() gains an optional timeBudgetMs for caller-chosen maintenance windows. - Documented trade stated where operators read: a long-lived writer that never closes accumulates history until its next explicit compactHistory() — predictable writes, explicit maintenance.

The 30s floor is configurable via transactionBudgetFloorMs for stores whose cold operations legitimately run long. - New brain.warm() eagerly loads the vector index, metadata index, and graph adjacency so first operations after a cold restart run at steady-state cost. Returns a WarmReport with an honest per-surface outcome (warmed / probed / unavailable) - never reports a probe as a warm. warmOnOpen: true runs it during init(). New optional provider hook warm() on the vector and graph plugin contracts. - Vector-index transaction op classes renamed from the backend-specific AddToHNSWOperation / RemoveFromHNSWOperation to backend-neutral AddToVectorIndexOperation / RemoveFromVectorIndexOperation, stamping the active backend into the emitted op-name string (AddToVectorIndex(js-hnsw) vs a native provider's own identity) so journals never misdirect an operator toward an index that isn't running. --- RELEASES.md | 56 ++++ src/brainy.ts | 205 +++++++++++- src/hnsw/hnswIndex.ts | 3 + src/index.ts | 3 + src/plugin.ts | 44 +++ src/transaction/Transaction.ts | 74 ++++- src/transaction/operations/IndexOperations.ts | 79 +++-- src/transaction/operations/index.ts | 6 +- src/types/brainy.types.ts | 36 ++ src/utils/metadataIndex.ts | 40 +++ tests/unit/brainy/warm.test.ts | 309 ++++++++++++++++++ .../budget-commit-completed-work.test.ts | 149 +++++++++ .../vectorIndexOperations-rename.test.ts | 152 +++++++++ 13 files changed, 1099 insertions(+), 57 deletions(-) create mode 100644 tests/unit/brainy/warm.test.ts create mode 100644 tests/unit/transaction/budget-commit-completed-work.test.ts create mode 100644 tests/unit/transaction/vectorIndexOperations-rename.test.ts diff --git a/RELEASES.md b/RELEASES.md index 7799c6f6..113b327d 100644 --- a/RELEASES.md +++ b/RELEASES.md @@ -31,6 +31,62 @@ is sometimes cited as a 7.x removal — those methods never existed on 7.x; the --- +## Unreleased (the warm contract: cold-restart writes stop paying demand-load latency) + +From a production deployment's cold-restart incident: the FIRST writes after every +restart on a large brain measured 33–35s each (page cache cold) against the transact +apply budget — Brainy's own op-count-scaled budget, `max(30s, opCount × 2s)`, e.g. +32,000ms for a 16-op batch.

Brainy itself never auto-retried the timeout; the gap was that TransactionTimeoutError only said "retryable" in prose, with nothing machine-readable for a caller to branch on. - TransactionTimeoutError gains two typed, always-true fields: retryable (a later attempt may succeed once the slowness resolves or the budget is raised) and hotRetryUnsafe (an immediate identical retry re-pays the full cost that just timed out and can cascade into a CPU storm -- callers must latch and back off, never loop). context's existing telemetry fields (timeoutMs, operationIndex, elapsedMs, totalOperations, operationName) are now documented as the caller's backoff inputs. - Updated the "retryable" doc-prose sites (transact()'s timeoutMs option, transactionBudgetFloorMs, Transaction.execute()'s contract) to point at the new fields instead of bare prose. - Regression pin (tests/unit/transaction/timeout-never-internally-retried.test.ts): an execution counter proves the engine never re-drives a timed-out operation, through both the single-op engine TransactionManager/Transaction drives for every single-record write, and add()'s upsert-race retry loop (which must exit on the first TransactionTimeoutError, never treat it like the lost-insert-race signal it retries on). - Removed TransactionManager.executeTransactionWithResult -- zero callers anywhere in the codebase. --- src/db/types.ts | 10 +- src/transaction/Transaction.ts | 7 +- src/transaction/TransactionManager.ts | 29 ---- src/transaction/errors.ts | 45 +++++- src/types/brainy.types.ts | 6 +- .../TransactionManager.unit.test.ts | 37 ----- .../timeout-never-internally-retried.test.ts | 141 ++++++++++++++++++ 7 files changed, 199 insertions(+), 76 deletions(-) create mode 100644 tests/unit/transaction/timeout-never-internally-retried.test.ts diff --git a/src/db/types.ts b/src/db/types.ts index 4c8a4957..a7f86a89 100644 --- a/src/db/types.ts +++ b/src/db/types.ts @@ -121,9 +121,13 @@ export interface TransactOptions { * with the batch: `max(30 000, opCount × 2 000)` — production imports on * network-attached disks measure ~2 s per operation, so a flat 30 s budget * silently capped honest bulk work at ~15 operations.

add maintenanceDebt() observability surface A production deployment's warm report showed metadata: 'unavailable' under a native metadata provider. brain.warm()'s metadata leg only duck-typed the built-in JS manager's hydrateAll() method, which a native provider has no reason to implement. - MetadataIndexProvider (src/plugin.ts) gains an optional warm?(): Promise hook, mirroring the existing vector and graph provider hooks. brain.warm() now checks the active provider's own warm() FIRST, falls back to the JS manager's hydrateAll() when absent, and reports 'unavailable' only when neither exists -- never init() as a stand-in, since a native provider's init() may be a cheap verify rather than a real warm. - Tests (tests/unit/brainy/warm.test.ts): a live provider instance shaped to have warm() reports 'warmed' and the hook called with no hydrateAll fallback; shaped to have neither hook reports 'unavailable' (pins the honest branch); the unmodified built-in JS manager still reports 'warmed' via hydrateAll(), unchanged. Additive scope agreed mid-flight with the native-provider team: a maintenance-debt observability seam so an operator sees a grind coming instead of discovering it as a CPU storm. - New optional maintenanceDebt?(): Promise hook on all three provider contracts (vector, metadata, graph -- the same three warm?() lives on). ProviderMaintenanceDebt is fields-all-optional: a provider reports only what it truly measures (pendingBytes, pendingItems, lastPassCompletedAt, lastPassOutcome, converging), never an estimate dressed as fact. - New public brain.maintenanceDebt(): a pure passthrough -- for each surface it calls only the active provider's own hook and reports the payload verbatim, or 'unavailable' when absent. No thresholds, no polling, no JS-side estimation; the provider owns the numbers, the operator owns the policy. - ProviderMaintenanceDebt, MaintenanceDebtReport, and MaintenanceDebtOutcome are exported from the package root. - Tests (tests/unit/brainy/maintenance-debt.test.ts): hook present reports 'reported' with the exact payload passed through; hook absent reports 'unavailable' on every surface; mixed surfaces resolve independently of each other.

A bare field name in `where` / `orderBy` / `groupBy` / aggregation + * `source.where` ALWAYS means the caller's own `metadata` field. 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 relationship map is system.verb, + * system.sourceId, system.targetId, plus the eight scalars shared with + * entities. + * 3. Some names are invisible plumbing and are never addressable in either + * spelling: vector, connections, level, data, _rev. `system.level`, + * `system.vector`, and `system.data` all refuse — they are not in the + * system map.

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`.

No guessing, +no priority rules. + +**3.

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 061/175] =?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 066/175] =?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).
