THE FALSE POSITIVE. stampEntityTree() recorded generationStore.generation() β€” the ALLOCATED counter, a number a write in flight has claimed and may never commit β€” 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() β€” a whole-store recount β€” 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 β€” 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 β€” 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 β€” a generation absent from committedRanges never appears, one still in the pending buffer is skipped, one whose tx.json will not read is skipped β€” 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 β€” 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 β€” 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 β€” ordinary close()-time repacking folds over the hole, then reopen and compact must both complete.

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" β€” 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 β€” `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` β€” "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 β€” 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 β€” one SIGTERM listener calling close() on every pooled store β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” 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.

(d) Eight kicks during a running flush β€” five through the cadence door, three direct β€” 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.

Every exit runs the same promotion β€” the leader resolving, the leader rejecting, the promoted run rejecting β€” 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 β†’ 4.9s as they contended * for the same providers. + * + * THE WAITER IS SETTLED BY THE MACHINE, NEVER BY A PROMISE CHAIN.

-0700 Subject: [PATCH 29/65] =?UTF-8?q?fix(shutdown):=20beforeExit=20never=20clo?= =?UTF-8?q?ses=20a=20live=20brain=20=E2=80=94=20a=20drained=20event=20loop?= =?UTF-8?q?=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 β€” close() β€” 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() β€” the engine's own non-closing durability door β€” 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 β€” noteWriteForPersistence() kicks the same call off an unref'd timer on every busy brain β€” 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 β€” 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 β€” valuesForIds β€” 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 β€” 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 β€” 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** β€” 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 β€” 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 β€” 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 β€” the pre-7.20.0 fallback, still read for workspaces that have not been rebuilt β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 38/65] 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 β€” 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 β€” tags, authors, categories, labels, participants β€” 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 β€” add, update, relate, updateRelation β€” 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 β€” 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 β€” per-dimension numeric field explosion β€” 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.

13:48:25 -0700 Subject: [PATCH 39/65] 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 β†’ read β†’ close rewrote FOUR files β€” `_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 β€” 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 β€” 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 β†’ read β†’ 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 β€” 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` β€” the flush body itself β€” 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 β€” 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 β€” 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 43/65] 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 β€” clone, shape validation, commit, or a rejected push β€” exits non-zero naming the cure; nothing is ever skipped. Both wall files are gone from this repo β€” 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 β€” 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 β€” 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 β€” 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 β€” 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, 3–4Γ— faster imports", - "items": [ - "Every runtime embeds with the same full-precision model β€” search quality no longer depends on where you run.", - "Bulk embedding measured 3.1–4.2Γ— 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 β€” Brainy", - "items": [ - "The former two-package pair is one package: the native engine under the familiar API.

It could not say WHICH, and the advice it gave β€” read the 'stdout | > ' prefix β€” 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 β€” `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 β€” more brains made than closed. This assertion is downstream of that, and the next red arrives with the stack that names which one. --- tests/integration/idle-costs-nothing.test.ts | 26 ++++++++++++++++---- 1 file changed, 21 insertions(+), 5 deletions(-) diff --git a/tests/integration/idle-costs-nothing.test.ts b/tests/integration/idle-costs-nothing.test.ts index 2374627e..7e664a28 100644 --- a/tests/integration/idle-costs-nothing.test.ts +++ b/tests/integration/idle-costs-nothing.test.ts @@ -70,8 +70,22 @@ describe('an idle brain costs nothing', () => { await brain.flush() const logged: string[] = [] + // The STACK behind each narration, kept beside the line it belongs to. + // vitest tags a stdout block with the test that is RUNNING, not the brain + // that wrote it, so teeing these lines through would only ever name this + // test.

Every later value of another kind was coerced to that type, and when coercion failed β€” `Number('electronics')` is NaN β€” 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 β€” the "has any value" probe behind `exists` β€” 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` β€” which writes `category` as strings in one test and as numbers in another against one shared brain β€” passes whole for the first time.
