6099101336 docs: remove stale distanceSQ8 JSDoc left by the SQ8 hook refactor
The native SQ8 distance hook renamed the original distanceSQ8 to distanceSQ8Js
and added a dispatcher in its place, but left the old function's doc block
orphaned above distanceSQ8Js (two consecutive comments, the first dangling).
Merge them into one accurate block on distanceSQ8Js with dash-notation params.

4b6f63ed67 feat: export provider contracts for the plugin surface brainy consumes
Native accelerators (cortex) register providers for metadataIndex, graphIndex,
hnsw, entityIdMapper, cache, columnStore, and aggregation. Until now the exact
method/property surface brainy calls on each was implicit — a provider could
drop a member brainy depends on and only fail at runtime when that path ran.

This defines and exports the provider contracts from the stable
@soulcraft/brainy/plugin entrypoint:
- MetadataIndexProvider, GraphIndexProvider, HnswProvider,
  EntityIdMapperProvider, CacheProvider — each typed as exactly the surface
  brainy calls (optional/feature-detected members like HNSW setPersistMode and
  enableCOW are intentionally excluded).
- Re-exports ColumnStoreProvider and AggregationProvider (and the aggregate
  types) from the same entrypoint so a plugin author can import the whole
  provider surface from one place.

Brainy's own baseline classes now `implements` these contracts
(MetadataIndexManager, GraphAdjacencyIndex, HNSWIndex, EntityIdMapper,
UnifiedCache), so the interfaces can never silently diverge from what brainy
ships — and any provider that declares `implements` gets a compile error the
moment brainy starts requiring a new member.

The embeddings/embedBatch providers stay typed by the existing EmbeddingFunction
(no duplicate interface added). Type-only changes; no runtime behavior change.

46fc7f2c4a feat: hook native sort:topK provider into search result ranking
Adds a swappable sort:topK seam for the find() result-ranking hot path. Brainy
ranks candidate results by relevance score then slices to offset+limit; for large
candidate sets that is an O(N log N) full sort even though only the page is kept.

New utils/resultRanking.ts exposes rankIndicesByScore (top-K index selection) with a
JS default (sortTopKIndicesJs) that is byte-identical in ordering to the previous
results.sort((a, b) => b.score - a.score) + slice: descending by score, stable ties
by original index (ES2019+ stable sort semantics). setSortTopKImplementation lets a
native provider (e.g. cortex's Rust partial-sort) replace it; the provider returns
indices into a scores array and only has to match the JS index ordering.

brainy.ts resolves the sort:topK provider in init() (same pattern as distance:sq8)
and wires both relevance-score sort sites in find() through rankIndicesByScore +
reorderByIndices. rankIndicesByScore validates a native provider's output (length,
range, no duplicates) and falls back to JS on any inconsistency, so a query never
returns wrong or duplicated results. No provider registered = unchanged JS behavior.

Tests: unit coverage of the dispatcher (JS ordering vs Array.sort across 200 random
trials incl. ties, provider routing, and fallback on bad/throwing providers) plus
find() integration proving ranking routes through a registered provider, that the
provider and JS fallback produce identical ids/scores on the same data, and that
pagination requests k = offset + limit with descending ordering.

00d14cfa93 feat: hook native SQ8 distance provider into HNSW reranking
Makes distanceSQ8 swappable via setSQ8DistanceImplementation and wires brainy.ts to
install a registered 'distance:sq8' provider (e.g. cortex's Rust SIMD), with the JS
distanceSQ8Js as the default fallback. The provider signature is byte-compatible with
the native cosineDistanceSq8, so HNSW SQ8 reranking transparently uses native distance
when cortex is loaded. Native==JS numeric equivalence is asserted by the cross-language
parity suite.

e23361c488 merge: storage binary-blob primitive across all adapters
Adds saveBinaryBlob/loadBinaryBlob/deleteBinaryBlob/getBinaryBlobPath to the
StorageAdapter contract and every adapter (FileSystem real path; remote/memory/
browser return null path). Enables zero-copy mmap-able .cidx segments and batch
vector I/O. blobPath convention matches @soulcraft/cortex byte-for-byte.

7493d8e33f fix: code-point string collation in LSM SSTable, COW trees/refs, sorted queries
Replaces localeCompare / raw relational operators with compareCodePoints (UTF-8
byte order) in the remaining persisted or native-facing comparison sites:
- SSTable sourceId sort + zone-map range check + binary search (graph LSM)
- COW TreeObject + RefManager name sorts (reproducible content hashes and ref
  listings across environments)
- getSortedIdsForFilter (numeric-aware; code-point for strings) so the JS sort
  fallback matches the native column store exactly

Deterministic across OS/Node/ICU and byte-identical to the native engine. No
migration: COW serialize/deserialize preserve stored order, so existing trees
keep their hashes; only new writes adopt code-point order.

298b572671 feat(storage): add raw binary-blob primitive to every storage adapter
Introduce a first-class binary-blob storage primitive on the StorageAdapter
contract and implement it across all storage backends. This stores opaque byte
payloads verbatim instead of base64-in-JSON, eliminating the ~33% inflation and
full-materialization cost of the JSON envelope. It unblocks zero-copy,
mmap-able column-store segments and batch vector I/O at billion scale.

New methods (declared abstract on BaseStorageAdapter, the class that implements
StorageAdapter, and added to the StorageAdapter interface):

  saveBinaryBlob(key, data)    raw write, atomic on real filesystems
  loadBinaryBlob(key)          exact bytes, or null if absent
  deleteBinaryBlob(key)        idempotent (missing is ignored)
  getBinaryBlobPath(key)       real local fs path where one exists, else null

Shared key -> location convention across every adapter: the key's
"/"-separated segments nest under a `_blobs/` prefix and are suffixed with
`.bin`, e.g. "graph-lsm/source/sstable-123" ->
"<root>/_blobs/graph-lsm/source/sstable-123.bin". Blobs are not branch-scoped
(COW): they are immutable producer-managed segments.

Per-adapter behavior:
- FileSystemStorage: writes under <rootDir>/_blobs via tmp+rename; returns the
  real on-disk path so native code can mmap it directly. Path convention matches
  the existing MmapFileSystemStorage subclass byte-for-byte.
- S3CompatibleStorage / R2Storage / GcsStorage / AzureBlobStorage: put/get/delete
  raw octet-stream objects; getBinaryBlobPath returns null (remote stores have no
  local path).
- MemoryStorage: defensive-copied Map<string, Buffer>; null path; cleared on
  clear().
- OPFSStorage: stores raw bytes in the OPFS tree; null path.
- HistoricalStorageAdapter: read-only — save/delete throw; load resolves the
  blob from the historical commit tree; null path.

Tests: tests/unit/storage/binaryBlob.test.ts exercises save/load round-trip
(byte-identical, incl. non-UTF8 bytes), overwrite, delete-then-load, load-missing,
and getBinaryBlobPath behavior for all eight adapters. Cloud adapters run against
in-memory client fakes that drive the real adapter code; OPFS runs against an
in-memory FileSystem Access API mock; the historical adapter commits a blob into
a real COW tree. 59 new tests; full unit suite (1398 tests) green.

547721ae14 fix: deterministic code-point string collation for column store + aggregation
Replace localeCompare (default-locale, non-deterministic across environments —
unsafe for a persisted sorted index) with UTF-8 byte / code-point order via a
shared compareCodePoints() helper. String ordering is now deterministic and
byte-identical to the native column store / aggregation sort, so results are the
same with or without the native accelerator. Covers the aggregate orderBy sort
and all 5 column-store comparison sites (tail buffer, merge sort, binary search).
Adds compareCodePoints unit tests.

fe4f5df8c9 feat: exact percentile and distinctCount aggregation ops
Add 'percentile' (with a 'p' fraction in [0,1]) and 'distinctCount' to the
aggregation engine. Both are exact, computed from a per-metric value multiset
(MetricState.valueCounts) maintained incrementally and delete-safe; percentile
uses numpy-linear interpolation. The multiset is JSON-serializable so results
survive persistence. 35 aggregation unit tests pass.

c2e21b7b3c feat: array-unnest groupBy for aggregates + batch-embed entity extraction
- groupBy now supports { field, unnest: true }: an entity contributes once per
  distinct element of an array field (tag frequency / faceted counts). Duplicate
  elements on one entity count once; an empty/missing array joins no group. The
  incremental add/update/delete paths fan out across the unnested groups.
- extractEntities/extractConcepts batch-embed the unique candidate spans in one
  embedBatch call instead of one embed() per candidate (N sequential model calls);
  falls back to per-candidate embedding if the batch fails. No behavior change.

1a98e4276a feat: queryAggregate() + HAVING, plus aggregate backfill, traversal depth/via, extraction typing (BR-ADV-FEATURES-BUN)
New report APIs:
- brain.queryAggregate(name, params) returns the clean AggregateResult[] shape
  ({ groupKey, metrics, count }) directly, instead of the search-Result wrapper that
  find({ aggregate }) returns.
- HAVING: find({ aggregate, having }) and queryAggregate filter groups by computed
  metric values (e.g. revenue > 1000), complementing where (which filters group keys).
  Evaluated per group: O(groups), independent of entity count.

Fixes (all reproducible on Node; surfaced under Cortex+Bun by Memory):
- Aggregate backfill-on-define: defining an aggregate over a store that already holds
  matching entities returned []. It now backfills from existing entities on first query
  (storage-agnostic via getNouns), so it works under durable backends that reopen
  pre-populated. groupBy:['noun'] resolves to the entity type; find({ aggregate }) rows
  expose groupKey/metrics/count at the top level.
- Multi-hop find({ connected: { depth, via } }) honors depth and via at every hop
  (was 1-hop only, with verb filtering applied to hop 1 only); BFS bounded by limit.
- extractEntities no longer bleeds a neighbour's type indicator across candidates; each
  candidate is typed by its own span. Also fixes the "Dr." title pattern.

Adds real-embedding regression tests; full unit suite green.

0a9d1d9a17 fix: extraction, multi-hop traversal, and aggregate result shape (BR-ADV-FEATURES-BUN)
Three advanced-API correctness fixes, all reproducible on Node (not Bun-specific):

- Entity/concept extraction returned []. SmartExtractor combined agreeing signals
  with a weighted sum compared against an absolute 0.60 gate, so a confident
  low-weight signal lost selection to a mediocre high-weight one that then failed
  the gate, dropping the whole result. Select and gate on a normalized weighted
  average instead. The public `confidence` option now controls the threshold (was
  a dead hardcoded 0.60), and the embedding-signal timeout is raised 100ms -> 2000ms
  so the neural signal is not silently dropped on slower runtimes.

- Multi-hop find({ connected }) returned only the 1-hop neighbour. executeGraphSearch
  ignored depth/via; it now delegates to the depth-aware neighbors() BFS.

- find({ aggregate }) hid groupKey/metrics/count under .metadata, so callers
  expecting AggregateResult saw empty rows. Expose those fields at the top level.

Adds real-embedding regression tests in tests/integration/advanced-apis-regression.test.ts.

07754d135a docs: storage-adapter inheritance contract + correct the hasStorageMethod story
Per the Cortex team's audit, the BR-CX-INTERFACE-GAP boot crash was a
build/install artifact (stale node_modules, lockfile drift, Docker cache,
bundler quirks), not a plugin-bundles-brainy version-skew issue. Cortex's
MmapFileSystemStorage extends FileSystemStorage and inherits all 6
multi-process helpers via the prototype chain at runtime; the dynamic
ESM import to @soulcraft/brainy is preserved in cortex's dist.

  - Rewrote the hasStorageMethod() doc comment to credit the real cause.
  - Updated the init-time warning to point operators at the actual fix:
    clean install or container rebuild to refresh node_modules.
  - New docs/concepts/storage-adapters.md documenting the inheritance
    contract: extend FileSystemStorage to inherit the multi-process
    helpers, override supportsMultiProcessLocking() -> true to activate.
    Includes a minimum checklist for adapter authors.
  - New docs/architecture/multiprocess-storage-mixin.md as a future-
    direction note: extracting the 7 methods into a
    MultiProcessSafeStorage interface/mixin is the architecturally clean
    next step, deferred to v8 or until a second multi-process capability
    lands.

No behavior changes. Ships with the next release.

70263113ad fix: find()/stats() correctness + Cortex compat (BR-FIND-WHERE-ZERO, BR-DEFENSIVE-INTERFACE)
Two production correctness defects fixed together so consumers can land
one upgrade.

BR-FIND-WHERE-ZERO — find() returned [] and stats() reported 0 entities
for any workspace whose data was written after the 7.20.0 column-store
refactor. Root cause: getStats() and the getIds() fallback still read
from the deleted sparse-index path. Separately, BaseStorage.getNounType()
was hardcoded to return 'thing', poisoning type-statistics.json with
every noun attributed to that bucket.

  - MetadataIndex.getStats() reads from ColumnStore + idMapper.
  - MetadataIndex.getIdsFromChunks() throws BrainyError(FIELD_NOT_INDEXED)
    when neither store has the field. getIdsForFilter() catches per
    clause, logs once, returns [].
  - BaseStorage.nounTypeByIdCache populated in saveNounMetadata_internal
    and consumed in saveNoun_internal. flushCounts() now persists the
    Uint32Array counters too, so readers see fresh per-type counts.
  - Self-heal at init: loadTypeStatistics() auto-rebuilds when the
    poisoned signature is detected. rebuildTypeCounts() is now public for
    use from `brainy inspect repair`.
  - Dead state removed: dirtyChunks, dirtySparseIndices,
    flushDirtyMetadata().

BR-DEFENSIVE-INTERFACE — 7.21.0 called supportsMultiProcessLocking()
unconditionally, crashing on older Cortex storage adapters that predate
the method. New hasStorageMethod(name) helper gates every new-method
call site. Older adapter triggers a one-line warning at init pointing
at the recommended plugin version.

Tests:
  - new tests/integration/find-where-zero.test.ts (7 cases)
  - new tests/integration/cortex-compat.test.ts (5 cases)
  - multi-process-safety.test.ts updated to enforce correct counts
  - 1329/1329 unit + 24/24 new integration tests passing

4fcdc0fef3 feat: multi-process safety + read-only inspector mode
Filesystem storage now enforces single-writer, many-reader semantics.
A second writer on the same data directory throws at init time with the
holder's PID, hostname, and heartbeat — replacing the previous silent
stale-reads failure mode.

- New: `Brainy.openReadOnly()` — coexists with a live writer, every
  mutation throws clearly.
- New: writer lock at `<rootDir>/locks/_writer.lock` with 10s heartbeat
  and stale-detection (PID liveness + heartbeat freshness).
- New: cross-process flush-request RPC (filesystem-based, no signals)
  so inspectors can force fresh state on demand.
- New: `brain.stats()`, `brain.explain(findParams)`, `brain.health()`
  for operator-facing introspection.
- New: `brainy inspect` CLI with 13 subcommands (stats, find, get,
  relations, explain, health, sample, fields, dump, watch, backup,
  repair, diff), all read-only by default.
- Same-PID re-opens allowed with a warning (preserves test "simulate
  restart" patterns).
- Storage instances passed directly via `storage: new MemoryStorage()`
  are now honoured instead of silently falling through to the
  filesystem auto-detect path.

Brainy + Cortex compose under this model — the lock covers both because
they share `rootDir`, Cortex segments are immutable mmap files, and
MANIFEST updates use atomic-rename.

11be039ae8 refactor: delete dead sparse index write path
Column store handles all writes and primary queries. Sparse index write
methods are unreachable:

Deleted: addToChunkedIndex (~103 lines), removeFromChunkedIndex (~37 lines),
splitChunkDeferred (~82 lines), getValueChunkFilename + makeSafeFilename
(~20 lines). Total: ~240 lines of dead write-path code.

Sparse index read methods kept as migration fallback for existing workspaces.
Will be deleted once lazy migration (buildFromStorage) ships.

46583f2d9b feat: unified column store for filtering + sorting at billion scale
Adds a per-field sorted column store (Lucene doc values + roaring bitmap
architecture) that replaces the MetadataIndex sparse index internals for
both filtering and sorting. One system for all field types with exact
precision — no bucketing, no per-entity storage reads.

Column store: binary .cidx segment format, in-memory tail buffers,
LSM-style compaction, k-way merge sort, multi-value support (__words__).
All queries (filter, range, sort, filtered sort) route through the column
store when data is available, falling back to sparse index otherwise.

Key unlocks:
- find({ orderBy: 'createdAt' }) works WITHOUT a filter (previously threw)
- find({ orderBy: 'metadata.price' }) works for custom numeric fields
- Exact timestamp precision (no 1-minute bucketing)
- O(K log S) sort independent of total entity count

New files: src/indexes/columnStore/ (types, format, tail buffer, cursor,
manifest, coordinator — ~700 lines). 101 new unit tests covering binary
format round-trips, CRC validation, sort, filter, range, deletion,
multi-segment merge, persistence, and multi-value (words) fields.

Deleted: metadataIndex-automatic-bucketing.test.ts (bucketing behavior
eliminated by exact-precision column store). Sparse index write path
removed from addToIndex/removeFromIndex. Sparse index legacy code still
present as dead code pending cleanup in next commit.

108e2bcab4 refactor: migrate aggregation + neural field reads to resolveEntityField
Preventive cleanup of sites that previously used dual-lookup patterns
(metadata[field] ?? entity[field]) or hardcoded timestamp if-chains
to read fields off HNSWNounWithMetadata. These worked today but were
fragile — the same failure mode that caused the orderBy sort bug
would have recurred the next time someone reordered or dropped a
lookup.

- AggregationIndex.computeGroupKey + getNumericField now route all
  dimension and metric field lookups through resolveEntityField.
- improvedNeuralAPI._getItemsByTimeWindow + _clusterItemsByField
  use resolveEntityField as the primary path, with item.data as a
  legacy producer fallback. The type/nounType legacy branch is
  preserved as-is since it handles storage format compatibility
  rather than shape contract drift.

No behavior change for correct inputs. All aggregation and orderby
regression tests pass unchanged.
2026-04-09 16:40:55 -07:00
beefacbca9 feat: export resolveEntityField + STANDARD_ENTITY_FIELDS from internals
Cortex and other first-party plugins need a shared contract for reading
fields off HNSWNounWithMetadata. Exporting from /internals keeps a single
source of truth and prevents the shape contract from drifting between
packages.
2026-04-09 16:28:54 -07:00
be6c4dc182 fix: correct orderBy sort for timestamp fields via centralized field resolver
Muse reported that find({ orderBy: 'createdAt' }) silently returned the
wrong order: getFieldValueForEntity read noun.metadata[field] for
timestamp fields, but getNoun() destructures standard fields to the top
level, so the read always returned undefined and the sort collapsed to
insertion order.

The fix introduces a single source of truth for reading fields off an
entity. STANDARD_ENTITY_FIELDS + resolveEntityField() in coreTypes.ts
encode the "standard fields top-level, custom fields nested" contract
in one place. getFieldValueForEntity now uses the helper and routes
through a named BUCKETED_INDEX_FIELDS set instead of a hardcoded
timestamp if-chain — filtered sort on createdAt/updatedAt now works.

Unfiltered orderBy is explicitly rejected with a clear error pointing
callers at the right pattern. A scalable, unfiltered-sort-capable
time-ordered segment index is tracked as a separate follow-up.
2026-04-09 16:26:38 -07:00
9d035aceee fix: metadata index corruption after restart — 6-point integrity fix
Root cause: metadata index failed to reconstruct after deploy restart
because the field registry file (__metadata_field_registry__) was lost
during an interrupted flush. init() silently assumed the workspace was
empty even though 5000+ entities existed on disk.

Fix 1 (root cause): init() now probes storage for entities when field
registry is missing. If entities exist, triggers rebuild instead of
silently skipping. Never trusts a missing registry as "empty."

Fix 2 (safety net): after rebuildIndexesIfNeeded(), verifies metadata
index entry count matches storage entity count. Forces second rebuild
if mismatch detected.

Fix 3 (prevention): flush() now always saves field registry and
EntityIdMapper, even when no dirty fields exist. These tiny files are
the critical link that init() needs to discover persisted indices.

Fix 5 (safe rebuild): rebuild() no longer deletes the field registry
file before rewriting. If rebuild fails partway, the registry survives
for the next init() to discover and re-trigger rebuild.

Fix 6 (collision guard): EntityIdMapper init() warns when mapper file
is missing but entities exist on disk, preventing silent ID collisions
from nextId starting at 1.
2026-03-24 12:57:11 -07:00
b58ea02de1 fix: commit() now flushes and captures state by default
commit() previously defaulted captureState to false, creating commits
with NULL_HASH tree that could never be restored from. Now:

- flush() runs first to persist deferred HNSW nodes, count batches,
  and index state before snapshotting
- captureState defaults to true, creating real content-addressed trees
- captureState: false still available for lightweight metadata-only commits

54865b3505 feat: add setMaxSize() for dynamic cache resizing
UnifiedCache.setMaxSize() allows runtime resizing of the cache maximum.
When the new limit is smaller than current usage, lowest-value items are
evicted until the cache fits. Used by Cortex's ResourceManager to
rebalance cache vs instance memory as brainy instances are created and
evicted in multi-tenant deployments.

Also adds getMaxSize() for observability.

60a0f1051f fix: suppress misleading 'Using Q8 WASM' log when Cortex native is active
EmbeddingManager constructor logged 'Using Q8 precision (WASM)' before

2026-03-22 14:53:48 -07:00
973b6aaa39 perf: defer HNSW persistence during addMany() batch operations
addMany() now temporarily switches the HNSW index to deferred persist
mode during the batch loop. Previously, each add() triggered ~16-20
saveHNSWData calls for modified neighbors (each a read→gzip→atomic-write
cycle). For 450 items this was ~8,100 individual storage writes.

With deferred mode, dirty node IDs are collected in a Set during the
batch and flushed once at the end — deduplicating repeated neighbor
updates. A node modified by insert #3 and again by insert #47 is
written only once.

Also adds setPersistMode() to TypeAwareHNSWIndex, propagating mode
changes to all existing type-specific sub-indexes.
2026-03-22 14:53:11 -07:00
c054c41943 fix: add rootDirectory to BrainyConfig.storage type
The storage config type only exposed { type, options, branch } but plugin
storage factories (e.g. Cortex mmap) read rootDirectory from the top level
of the config object. This caused undefined storage paths when Cortex was
active. The underlying StorageOptions interface already declares
rootDirectory — this aligns BrainyConfig.storage to match.

239a4da835 fix: replace require('crypto') with ESM import in SSTable
SSTable.calculateChecksum() used require('crypto') which breaks in ESM

a direct node:crypto import is appropriate.

1a628daa83 fix: metadata index not cleaned up after delete/deleteMany
Three bugs caused deleted entities to persist in the metadata index:

1. idMapper never cleaned up — EntityIdMapper accumulated UUID→int mappings
   permanently. idMapper.getAllIntIds() is used as the universe for ne and
   exists:false operators, so deleted entities returned in those queries
   indefinitely. Fix: removeFromIndex() now calls idMapper.remove(id) and
   idMapper.flush() after all bitmap operations complete (must be last because
   removeFromChunk() reads idMapper.getInt(id) internally).

2. Optional fields indexed as __NULL__ but never unindexed — entityForIndexing
   in add() included confidence, weight, and createdBy as explicit keys even
   when undefined. Object.entries() preserves undefined-valued keys so
   extractIndexableFields() indexed them as '__NULL__' bitmap entries.
   storageMetadata omitted those keys via conditional spreading, so
   removeFromIndex() passed a structure without those keys and never cleaned
   them up. Fix: entityForIndexing now uses conditional spreading for
   confidence, weight, and createdBy matching storageMetadata exactly.

3. result.successful updated before transaction commits — deleteMany() pushed
   ids to result.successful inside the transaction builder, before
   transaction.execute() ran. A rollback would leave result.successful
   containing ids that were never actually deleted. Fix: queued ids are held
   in a local chunkQueued array and moved to result.successful only after
   executeTransaction() resolves without throwing.

Adds regression test suite (14 tests) covering delete() and deleteMany() for
type-index cleanup, ne operator, exists:false operator, optional-field indexing,
and partial deletion correctness.

0ddc05a5bb feat: enforce data/metadata separation, numeric range queries, improved docs
- Store data opaquely in add() and update() instead of spreading object
  properties into top-level metadata. data is for semantic search (HNSW),
  metadata is for structured where-filter queries (MetadataIndex).
- Fix numeric range queries in MetadataIndex — use numeric-aware comparison
  instead of lexicographic string comparison for normalized values.
- Add data field to RelateParams and Relation types for relationship content.
- Add where.type → where.noun alias in metadata-only find() path.
- Rewrite README: focused ~350 lines from 791, quick start first, feature
  showcase with mini-snippets, organized doc links, no version callouts.
- Add DATA_MODEL.md and QUERY_OPERATORS.md reference docs.
- Remove 10 outdated/redundant doc files consolidated into API reference.
- Improve JSDoc on Entity, Relation, AddParams, FindParams, and core methods.
- Fix tests asserting data properties appear in metadata (data model violation).
- Deprecate verb.source/target in favor of from/to (public) and sourceId/targetId (storage).

932fb9520b fix: set verb.source/target to entity UUID instead of NounType
relate() was setting verb.source = fromEntity.type (a NounType like
"concept") instead of the entity UUID. Cortex's graph index indexes by
verb.source, so lookups by UUID found nothing — causing in-session
reads to return 0 results.

Also fixes:
- PathResolver calling private getIdsFromChunks() → public getIds()
- Plugin auto-detection removed; cortex loads only via explicit config
- GraphVerb types accept number timestamps and sourceId/targetId aliases
- Dead autoDetect() method removed from PluginRegistry
- In-session regression tests added for getRelations after relate()

6625385913 feat: add explicit plugins config to control plugin auto-detection
Previously, plugins: [] still auto-detected cortex because autoDetect()
always tried importing @soulcraft/cortex regardless of config. Now:
- undefined (default): auto-detect installed plugins
- false: no plugins, skip auto-detection entirely
- []: no plugins, skip auto-detection entirely
- ['@soulcraft/cortex']: load only specified, no auto-detection

Also adds typed plugins field to BrainyConfig interface.

ab2493af02 fix: flush graph LSM-trees on close to prevent data loss across restarts
GraphAdjacencyIndex.flush() was a no-op — LSM MemTables were never
written to SSTables for datasets under the 100K auto-flush threshold.
This caused readdir, getRelations, and getDescendants to return empty
results after close + reopen.

Three fixes:
- LSMTree.get(): merge MemTable + SSTable results (data spans both
  after flush, old early-return missed SSTable data)
- GraphAdjacencyIndex.flush(): actually flush all 4 LSM-trees
- GraphAdjacencyIndex.close(): close all 4 trees (was only closing 2)

Also: brain.close() and shutdown hooks now call close() on graphIndex,
HNSW index, and metadataIndex to release timers and file handles.
2026-02-01 17:55:40 -08:00
773c5171c3 fix: flush all native providers on shutdown to prevent data loss
Shutdown/close/flush now properly flushes all 4 components in parallel:
metadataIndex, graphIndex, HNSW dirty nodes, and storage counts. Previously
only counts were flushed, causing native provider data loss on restart.

Also:
- Wire roaring, msgpack, entityIdMapper provider consumption from plugins
- Fix allOf filter O(n²) intersection → O(n) Set-based
- Fix ne/exists negation filter to use Set-based exclusion
- Add setMsgpackImplementation() swap in SSTable for native msgpack
- Add setRoaringImplementation() swap for native CRoaring bitmaps
- Add getAllIntIds() to EntityIdMapper for bitmap operations
- Remove TypeAwareHNSWIndex from default index creation path
- Export memory detection utilities from internals
- Clean up 26 permanently-skipped dead tests

401e300ff2 feat: harden plugin system wiring and add developer diagnostics
Fix critical wiring bugs that prevented plugin-provided implementations
from being used at runtime. All CRUD operations, fork/checkout/clear,
batch embedding, neural APIs, and VFS path resolution now properly
dispatch through the plugin registry.

Changes:
- Wire graphIndex to storage for getVerbsBySource() fast path
- Replace instanceof checks with duck-typing (indexIsTypeAware flag)
  so plugin HNSW indexes work in add/update/delete/search
- Add createIndex() shared helper for plugin HNSW factory
- Fix fork/checkout/clear to use plugin factories for metadataIndex,
  graphIndex, and HNSW instead of hardcoding JS constructors
- Add three-tier embedBatch priority: embedBatch > embeddings > WASM
- Skip WASM warmup/eagerEmbeddings when plugin provides embeddings
- Fix PathResolver metadataIndex access (was looking on storage)
- Use global UnifiedCache in SemanticPathResolver
- Wire plugin distance function through neural APIs
- Add diagnostics() method and CLI command for provider inspection
- Add requireProviders() for production fail-fast assertions
- Add init-time provider summary log
- Add plugin developer documentation (docs/PLUGINS.md)
- Export DiagnosticsResult type

d1db3510be refactor: remove augmentation system and semantic type matching
Remove the entire augmentation pipeline infrastructure (52 files,
~15,000 lines) and the semantic type matching system. These were
unused middleware layers adding complexity without value.

What was removed:
- src/augmentations/ directory (all augmentation implementations)
- src/augmentationManager.ts (pipeline orchestrator)
- src/types/augmentations.ts, src/types/pipelineTypes.ts
- src/shared/default-augmentations.ts
- Semantic type suggestion (BrainyTypes.suggestNoun/suggestVerb)
- src/utils/typeMatching/ (embedding-based type matcher)

What was preserved by relocating:
- Import handlers (CSV, PDF, Excel) -> src/importers/handlers/
- NeuralImportAugmentation -> src/cortex/neuralImportAugmentation.ts
- Type matching utilities -> heuristic inference in consumers

What was simplified:
- brainy.ts: operations call storage directly (no execute() wrapper)
- IntegrationBase: standalone class (no BaseAugmentation parent)
- BrainyTypes: validation-only (nouns, verbs, isValid*, get*)
- Pipeline: direct execution (no augmentation interception)
- index.ts: removed TypeSuggestion, suggestType exports
- package.json: removed stale types/augmentations export

Build passes, 1176 tests pass, 0 failures.

0f3a88429d feat: add SQ8 vector quantization, lazy loading, and two-phase rerank to HNSW
- SQ8 scalar quantization (8-bit) for 4x vector storage reduction
- Lazy vector loading: evict float32 vectors after graph construction,
  load on-demand from storage via UnifiedCache
- Two-phase search: over-retrieve with SQ8 approximate distances,
  rerank top candidates with exact float32 distances
- Configuration surface: hnsw.quantization and hnsw.vectorStorage in BrainyConfig
- All features disabled by default (zero behavior change for existing users)
- 27 new tests covering quantization accuracy, lazy loading, reranking
- Remove GitHub Actions CI (build locally, cortex CI handles native builds)

1513e297ef feat: wire plugin system with provider resolution, storage factories, and browser deprecation
- Wire PluginRegistry into Brainy init() with provider resolution for distance,
  metadataIndex, graphIndex, embeddings, roaring, msgpack, and storage adapters
- Add setupStorage() factory that resolves storage:* providers from plugins before
  falling back to built-in createStorage()
- Export internals API (setGlobalCache, UnifiedCache, EntityIdMapper, etc.) for
  cortex plugin consumption
- Add plugin.test.ts verifying registration, activation, and provider resolution
- Deprecate browser support (OPFS, Web Workers, WASM embeddings) with warnings
  in preparation for v8.0 server-only release
- FileSystemStorage: fix setupStorage resolution for mmap-filesystem provider
2026-01-31 12:02:13 -08:00
cc50ac3776 feat: add plugin system for cortex and storage adapters
Simple plugin architecture with two use cases:
1. Native acceleration (@soulcraft/brainy-cortex) — auto-detected
2. Custom storage adapters (e.g., Redis, DynamoDB)

Plugins implement BrainyPlugin interface with activate/deactivate lifecycle.
Auto-detection tries dynamic import of known packages during init().
Manual registration via brain.use(plugin) before init().

Provider keys: metadataIndex, graphIndex, entityIdMapper, cache, hnsw,
roaring, embeddings, distance, msgpack, storage:<name>

35cb674157 perf: optimize init() and rebuild performance
- Remove detectAndRepairCorruption from init() hot path — was loading all
  metadata chunks sequentially on startup. Now available via checkHealth()
  and repairIndex() methods.
- Short-circuit warmCache on empty workspace — skip 4-6 wasted storage reads.
- Parallelize MetadataIndex.init() and getGraphIndex() via Promise.all().
- Defer metadata writes during rebuild to batch boundaries (every 5000
  entities) instead of flushing per-entity.
- Skip pre-reads for new entities in transactions — saves 2 storage
  round-trips per add() on cloud storage.
2026-01-31 09:14:51 -08:00
92d9420a5c fix: eliminate cloud storage write amplification and rate limiting
brain.add() was generating 26-40 immediate cloud writes per call, causing
HTTP 429 rate limit errors and high latency on GCS/S3/R2/Azure. Three-layer
fix: (1) deferred metadata writes with dirty-marking, (2) MetadataWriteBuffer
for write coalescing, (3) retry/backoff on all cloud storage adapters.
2026-01-31 09:09:36 -08:00
23e1c56ae0 fix: distribute metadata index keys across sub-prefixes to avoid cloud rate limits
All metadata index files were stored under a single _system/ prefix, causing
per-prefix rate limiting on GCS/S3/R2/Azure during cold starts and bulk imports.
Distributes high-volume system keys across 256 sub-prefixes using FNV-1a hash.
Backward-compatible with legacy path fallback.
2026-01-31 09:09:23 -08:00
66d7aa736c fix: invalidate VFS caches recursively on rmdir to prevent orphaned reads
When rmdir({ recursive: true }) deleted a directory tree, child file paths
remained in contentCache and statCache, causing readFile() to return stale
data for deleted files. Adds recursive flag to invalidateCaches() that
evicts all descendant keys by prefix.

df7d467a4b perf: optimize addMany() with batch embedding for 5-10x speedup
Uses embedBatch() to pre-compute all vectors in a single WASM forward
pass instead of N individual embed() calls. Items that already have
vectors are skipped.

Before: 100 entities = 100 separate WASM calls
After:  100 entities = 1 batched WASM call (micro-batched internally)
2026-01-28 08:50:24 -08:00
f8dd93c93c fix: cancel abandoned highlight() semantic work and harden WASM engine recovery
highlight() used Promise.race with a 10s timeout, but the losing
semantic phase promise continued running 25 WASM micro-batches,
saturating the event loop and degrading all subsequent operations
(find() going from ~200ms to ~10,000ms).

Add AbortController to highlight() so the semantic phase stops
immediately on timeout or error. Pass abort signal through
embedBatch() → EmbeddingManager → micro-batch loop.

Also add defensive hardening:
- CandleEmbeddingEngine: try/catch around WASM calls resets engine
  state on failure so next call triggers re-initialization
- WASMEmbeddingEngine: initialize() now checks underlying Candle
  engine state, not just its own flag, completing the recovery chain
