Brainy 8.0 makes subtype required by default on every public write path
(`add`, `addMany`, `update`, `relate`, `relateMany`, `updateRelation`,
import). Per the locked C-1 contract, every entity and relation gets a
non-empty subtype string by the time the storage layer sees it.
OPT-OUT REMAINS FULLY SUPPORTED
The runtime flag is still consumer-controlled. Three opt-out paths
cover migration / legacy fixtures / typed escape:
- `new Brainy({ requireSubtype: false })` — last-resort: turn off the
contract entirely. Recommended only for migration windows or test
fixtures that legitimately can't supply a subtype.
- `new Brainy({ requireSubtype: { except: [NounType.Thing, ...] } })` —
per-type allowlist: strict everywhere except the listed types.
- `brain.requireSubtype(type, options)` — per-type registration with
optional vocabulary. Composes with the brain-wide flag.
Default is now `true`. Opt-out is explicit and documented; nothing
silently degrades.
TEST SWEEP
Bulk-applied `requireSubtype: false` to every `new Brainy({...})` call
site across 120 test files. Three sed patterns covered the shapes:
- `new Brainy({` → `new Brainy({ requireSubtype: false,`
- `new Brainy<T>({` → `new Brainy<T>({ requireSubtype: false,`
- `new Brainy()` → `new Brainy({ requireSubtype: false })`
tests/helpers/test-factory.ts → createTestConfig() defaults
`requireSubtype: false` so test files using the helper inherit the
opt-out without per-site edits.
The test sites that DO exercise subtype semantics (the
subtype-and-facets suite, the strict-mode-self-test suite, the verb-
subtype-and-enforcement suite, etc.) already pass real subtypes — they
were the 7.30.x acceptance tests for this contract. Those tests
continue to pass unchanged.
CHANGES
src/brainy.ts
- normalizeConfig() — `requireSubtype` default `false` → `true`.
Comment refreshed to document the three opt-out paths.
tests/* (120 files)
- Bulk-edited brain construction sites. No functional test changes; the
opt-out preserves the test author's original intent.
tests/helpers/test-factory.ts
- createTestConfig() base config gains `requireSubtype: false`.
NO-OP for consumers who were already passing subtype on every write.
For consumers who weren't, the upgrade path is one of the three opt-out
forms above. Migration recipe documented in 8.0 release notes (next
commit).
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1408 / 1409 (same pre-existing race-condition outstanding;
no other regressions from the flip)
Step 6 of the brainy 8.0 rename scaffolding. Removes every legacy 'hnsw'-
flavoured public name introduced as a compat shim in steps 1-5. The
algorithm-neutral surface is now the only surface.
REMOVED — PHASE A (type aliases)
src/plugin.ts
- Removed `export type HnswProvider = VectorIndexProvider` alias.
- Removed `export type DiskAnnProvider = VectorIndexProvider` alias.
src/index.ts
- Removed `export const HNSWIndex = JsHnswVectorIndex` alias.
src/types/brainy.types.ts
- Removed `BrainyStats.indexHealth.hnsw` field (the new `vector` field
carries the same boolean).
src/brainy.ts
- `stats()` no longer emits the legacy `hnsw` field on `indexHealth`.
REMOVED — PHASE B (storage adapter rename, 8 adapters)
Repo-wide rename: `saveHNSWData` → `saveVectorIndexData` and
`getHNSWData` → `getVectorIndexData` across:
- src/storage/adapters/baseStorageAdapter.ts (abstract declarations)
- src/storage/adapters/fileSystemStorage.ts
- src/storage/adapters/gcsStorage.ts
- src/storage/adapters/r2Storage.ts
- src/storage/adapters/s3CompatibleStorage.ts
- src/storage/adapters/azureBlobStorage.ts
- src/storage/adapters/opfsStorage.ts
- src/storage/adapters/memoryStorage.ts
- src/storage/adapters/historicalStorageAdapter.ts
- src/brainy.ts (call sites)
- src/hnsw/hnswIndex.ts + src/hnsw/typeAwareHNSWIndex.ts (call sites)
The default-delegation wrappers added in scaffold step 4 are removed
(would have been duplicate declarations after the rename).
REMOVED — PHASE C (cache category 'hnsw')
src/utils/unifiedCache.ts
- Cache-category union narrowed from
'hnsw' | 'vectors' | 'metadata' | 'embedding' | 'other'
to
'vectors' | 'metadata' | 'embedding' | 'other'
- typeAccessCounts, typeSizes, typeCounts, accessRatios, sizeRatios,
and the fairness-check iterator all drop the 'hnsw' key.
- Per planning § 2.5: pre-8.0 'hnsw' cache entries are an in-memory
category. Cache is rebuildable; entries naturally don't exist after
a restart, so no migration path is needed.
src/hnsw/hnswIndex.ts
- 3 cache.set() call sites migrated from category 'hnsw' to 'vectors'.
- Cache key prefix `hnsw:vector:` → `vector:`.
- typeCounts/typeSizes/typeAccessCounts accessor renames
`.hnsw` → `.vectors`.
tests/unit/utils/unifiedCache-eviction.test.ts
- Test fixtures updated: cache.set(..., 'hnsw', ...) → cache.set(..., 'vectors', ...).
- Stats assertion `stats.typeSizes.hnsw` → `stats.typeSizes.vectors`.
REMOVED — PHASE D (config.hnsw)
src/types/brainy.types.ts
- Removed `BrainyConfig.hnsw` field entirely. The 8.0 surface is
`BrainyConfig.vector.{recall, quantization, vectorStorage, advanced}`.
src/brainy.ts
- normalizeConfig() no longer emits a `hnsw` field on Required<BrainyConfig>.
- setupIndex() rewired:
- Reads from `this.config.vector` (not `this.config.hnsw`).
- Calls `resolveJsHnswConfig(this.config.vector)` to translate the
`recall` preset into M / efConstruction / efSearch knobs (with
`advanced.hnsw` overrides winning when supplied).
- Imports `resolveJsHnswConfig` from './utils/recallPreset.js'.
NOT IN THIS COMMIT (deliberately)
- Persisted file path migration `_system/hnsw-*.json` →
`_system/vector-index-*.json`. Requires dual-read logic on boot
across 8 storage adapters. Per integration doc lines 531-539:
"Reader accepts either spelling on load; writer emits the new spelling
only; brains self-migrate on the next persist after upgrade." This is
a separate body of work and lands in a follow-up commit before 8.0 GA.
- `config.hnswPersistMode` top-level field is unchanged. It's not in
the rename inventory; a future commit can fold it into
`config.vector.persistMode` if desired.
- strictConfig enforcement wiring. The field is accepted by
normalizeConfig() with default 'warn'; the actual warning emission at
knob-mismatch sites lands when the config-resolution layer is touched
for the persisted-path migration.
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1468 / 1468 unit (one test fixture updated to use the new
category name; assertion still passes after fixture rename)
- npm run build: clean
The 8.0 PR's user-facing surface is now algorithm-neutral end-to-end:
VectorIndexProvider, config.vector.recall, JsHnswVectorIndex,
saveVectorIndexData, 'vectors' cache category, indexHealth.vector,
strictConfig — all standalone. No legacy 'hnsw' name remains in any
public type or method signature.
Brainy 7.30.0 introduced a memory-derived synchronous cap on `find({ limit })`
to prevent OOM. The cap was sound in intent but ~4x too conservative in
calibration: assumed 100 KB per result while typical entity footprint is 7-10 KB
(384-dim float32 vector ≈ 1.5 KB + standard fields + metadata). On a 900 MB
free-memory box the cap derived to 9000 — breaking common safety-cap patterns
like `find({ type, where, limit: 10_000 })` that typically return 10-500
entities. Surfaced as a runtime regression with cascading 500s degrading
production dashboards.
Three concurrent fixes:
A. RECALIBRATE THE FORMULA
- src/utils/paramValidation.ts:175,196,212 — the three memory-derived priorities
(reservedQueryMemory / containerMemory / freeMemory) all divided by
100 * 1024 * 1024 (100 KB per result, ~10-15x over conservative). Replaced
with a new MAX_LIMIT_KB_PER_RESULT = 25 constant that matches observed
entity size.
- Result: 4 GB container cap goes 10_000 → 40_000; 2 GB cap goes 5_000 →
20_000; 900 MB free-memory cap goes 9_000 → ~36_000. 100k hard ceiling
unchanged. `maxQueryLimit` / `reservedQueryMemory` constructor overrides
unchanged in behavior.
B. TWO-TIER ENFORCEMENT (warn-then-throw)
- Below cap (limit <= maxLimit): silent pass, unchanged.
- Soft tier (maxLimit < limit <= 2 * maxLimit): NEW — one-time warning per
call site (dedup keyed on caller stack frame + limit value), query
proceeds. Pre-7.30.2 code that relied on the cap silently allowing typical
safety-cap limits keeps working; the warning teaches the recipe so consumers
can fix it intentionally.
- Hard tier (limit > 2 * maxLimit): throw with the same teaching message
format. Real OOM territory; the cap stops being a recommendation and becomes
a guardrail.
- The 2x soft margin absorbs typical safety-cap patterns (limit: 10_000
against a 9 K-cap box) without disabling OOM protection. Real OOM territory
on a JS in-memory brain is hundreds of thousands of results, not 10x the
safety cap.
C. IMPROVED ERROR / WARNING MESSAGE
- Same shape as the 7.30.1 enforcement-error messages: state the problem,
name the three escape valves (maxQueryLimit / reservedQueryMemory /
pagination), include caller location, link to docs.
- Extracted findCallerLocation() helper from brainy.ts to a new
src/utils/callerLocation.ts so both the subtype enforcement (7.30.1) and
the limit enforcement (7.30.2) share one implementation without circular
imports.
DOCS
- New docs/guides/find-limits.md (public: true) — full reference: why the cap
exists, the four memory sources the auto-config considers, the three escape
valves with when-to-use-which guidance, and an explicit "pagination is the
future-proof pattern" callout (8.0 may tighten the cap further; pagination
keeps working unchanged).
- docs/api/README.md find() entry gets a one-paragraph `limit` tip + pointer
to the new guide.
- RELEASES.md v7.30.2 entry.
TESTS
- New tests/integration/find-limits.test.ts (9 tests): below-cap silent pass;
soft-tier warns once per call site (dedup verified by exercising same vs.
different source lines via wrapper closures); soft-tier message format
(names all three escape valves + docs link); soft-tier message includes
caller location; hard-tier throws; hard-tier message format same as
soft-tier; consumer maxQueryLimit override raises the cap and shifts both
tiers accordingly; pre-7.30.2 regression scenario explicitly covered.
- tests/unit/utils/memoryLimits.test.ts — 4 tests updated for the recalibrated
cap values (hardcoded expected numbers bumped 4x to match new 25 KB/result
assumption).
- tests/unit/utils/paramValidation.test.ts — auto-limit test extended to cover
the three-tier semantics (below-cap pass / soft-tier silent / hard-tier
throw).
- Existing suites unchanged: subtype-and-facets 26/26, verb-subtype-and-
enforcement 30/30, strict-mode-self-test 13/13. Unit 1468/1468.
CORTEX COMPATIBILITY
- Zero Cortex changes required. Every change is JS-side: formula recalibration
runs in ValidationConfig.constructor(), two-tier enforcement runs in
validateFindParams(), both fire before any storage / index / Cortex call.
- The new guide notes that Brainy 8.0's Datomic-style Db.find() may tighten
per-call limits to keep snapshot semantics cheap; pagination remains the
pattern that's guaranteed to keep working.
REPO-WIDE CLEANUP
Brainy is the only Soulcraft project that is open source. This commit also
scrubs closed-source product names and product-specific class/field references
from every tracked file in the repo (src/, docs/, tests/, RELEASES.md,
CHANGELOG.md). Consumer-reported bugs, regression scenarios, and release
notes now refer to "a consumer", "a downstream application", "a production
deployment", or "an internal report" — never to the named product. Two
product-named test files renamed to neutral diagnostic names. CLAUDE.md gains
a project-level guard rule documenting the policy and an example list of the
identifiers that may not appear in tracked code.
Verification
- npx tsc --noEmit: clean
- npm test: 1468 / 1468 unit
- All four integration subtype + verb + strict + find-limits suites: 78/78
- npm run build: clean
- Closed-source product reference audit: clean
The JS fallback EntityIdMapper caps at u32::MAX to match the metadata
index's Roaring32 bitmap width. Before this guard, a brain past 4.29 B
entities would silently widen `nextId` into JS's safe-integer range,
truncating ints inside the bitmaps and zeroing query results — the
same silent under-count cortex 3.0's Piece 10 just closed on the
native path. Brainy 8.0 surfaces the overflow loudly instead.
When `nextId` would exceed `U32_ENTITY_ID_MAX`, `getOrAssign` throws
`EntityIdSpaceExceeded` with a message pointing at the cortex 3.0
binary mapper's `idSpace: 'u64'` mode as the migration path (mmap-
backed extendible-hash KV, persists the full u64 range losslessly).
The existing-UUID lookup path bypasses the guard — only fresh
allocations can overflow.
Surfaces via `@soulcraft/brainy/internals`:
- `EntityIdMapper` (already exported, behavior gated)
- `EntityIdSpaceExceeded` (new)
- `U32_ENTITY_ID_MAX` (new constant, = 0xFFFF_FFFF)
This is the lockstep half of cortex 3.0 / Piece 10 / Step 15. Cortex's
`NativeBinaryEntityIdMapperWrapper` ships the U64 binary mapper that
takes over above this ceiling; brainy ships the bright-line failure
that points consumers at it.
New test: tests/unit/utils/entity-id-mapper-u32-ceiling.test.ts (6
assertions covering the constant, the error shape, normal
allocations, the boundary case at exactly u32::MAX, the overflow
throw, and the existing-uuid lookup bypass).
Brainy now has a complete reference SQ4 (4-bit per dimension, 8× compression
vs float32) quantization layer in src/utils/vectorQuantization.ts: quantizeSQ4,
dequantizeSQ4, distanceSQ4Js, serializeSQ4, deserializeSQ4 — all byte-for-byte
identical to cortex's Rust quantize_sq4 / dequantize_sq4 / cosine_distance_sq4.
The pack format mirrors cortex exactly:
- Two nibbles per byte. High nibble = vector[2i], low nibble = vector[2i+1].
- Odd-dim vectors place the final value in the high nibble and pad the low
nibble with 0. Packed length = ceil(dim / 2).
- Zero-range vectors (all values identical) map every nibble to 8 (midpoint
of [0, 15]) — both reference impls produce 0x88 bytes.
The active-fn dispatch pattern matches SQ8: distanceSQ4Js is the pure-JS
reference; distanceSQ4 routes through a swappable activeSQ4Distance slot;
setSQ4DistanceImplementation(fn) swaps in cortex's SIMD Rust distance when the
distance:sq4 provider is registered. brainy.ts wires the provider in init,
same shape as the existing SQ8 wiring (~14 LOC). The dispatch path is the
single point of integration so HNSW search code never needs to know whether
it's running on JS or native.
Serialization adds a uint32 dim field after min/max (12-byte header total) —
SQ8 doesn't need it because the packed length equals dim, but SQ4's packed
length rounds up so dim must be recorded explicitly to disambiguate the
trailing pad nibble.
Tests (1462 total, +15):
- Pack format: high-nibble-first, odd-dim trailing pad = 0, ceil(dim/2) length
- Round-trip error envelope: every reconstructed value within half a quantum
step of the original (verified across dims 1, 2, 3, 4, 16, 17, 384, 385, 1000)
- Edge cases: empty input throws, zero-range maps to 0x88, out-of-range
clamping
- distanceSQ4Js agreement with dequantize-then-cosine baseline within 1e-9
- dispatch swap (setSQ4DistanceImplementation): swap in a sentinel fn, observe
the active fn changes, restore the JS default, observe the revert
- serialize/deserialize round-trip preserves all four fields byte-for-byte for
both even and odd dim
The HNSW SQ4 reranking path (bits === 4 routing in HNSWIndex's quantization
config) is wired to use distanceSQ4 — when cortex's distance:sq4 provider
is registered, that hot path immediately becomes native SIMD with zero brainy
change required. Cross-language byte-format parity tests run in the cortex
test suite (paired release brainy 7.28.0 + cortex 2.5.0).
Cortex already registers the vectorStore:mmap provider (its Rust
NativeMmapVectorStore), but brainy has never consumed it — preloadVectors
and getVectorSafe still go straight to storage.getNounVector for every id,
even when an mmap layer is available. This wires the consumer end.
Architecture:
- NEW MmapVectorBackend (src/hnsw/mmapVectorBackend.ts) — bridges brainy's
UUID-keyed vector reads to a int-slot mmap file via the
vectorStore:mmap provider. Slots are addressed by the stable int id
from the post-2.4.0 #1 EntityIdMapper (the foundation this depends on).
Auto-grows the file (doubling) when a write lands beyond capacity, so
HNSWIndex never has to think about sizing. The class never touches
per-entity storage — it owns only the mmap layer.
- HNSWIndex changes — adds a vectorBackend field + a setVectorBackend
setter. The vector read paths (preloadVectors, getVectorSafe) try the
mmap layer first; on a storage fallback hit, they LAZILY write back into
the mmap slot. An upgraded install converges to the zero-copy fast path
under live traffic — no big-bang migration step. The legacy per-entity
path is preserved and still used when no backend is set.
- brainy.ts wiring — a new private wireMmapVectorBackend() runs once
during init, after plugin activation + metadataIndex setup. It activates
the backend only when (a) the vectorStore:mmap provider is registered,
(b) the storage adapter resolves a real local path via
getBinaryBlobPath(), and (c) the metadata index exposes its idMapper.
Cloud adapters return null on (b) and the backend is silently skipped;
HNSWIndex's behaviour is then identical to pre-2.4.0.
- Provider interfaces in plugin.ts — VectorStoreMmapProvider and
VectorStoreMmapInstance document the contract cortex's class fulfils
(the class IS the provider — static factory methods). Brainy depends on
the interfaces, not on cortex; the structural match is verified when
cortex 2.4.0 picks up this brainy release.
Tests (1428 total, +11 vs pre-2.4.0):
- tests/unit/hnsw/mmap-vector-backend.test.ts — 6 unit tests with an
in-memory mock provider. Covers round-trip, batch reads with interleaved
misses, slot stability (no re-slotting on overwrite), file growth without
data loss, idempotent open, and null returns for unwritten slots. The
real perf integration with cortex's NativeMmapVectorStore is exercised
when cortex 2.4.0 wires this in.
- tests/unit/utils/entity-id-mapper-stability.test.ts — moved here from
tests/regression/ (which is NOT in the unit-config include glob, so the
five #23 tests were not actually being run by npm test). The unit
config matches tests/unit/**/*.test.ts.
The 2.4.0 #2 follow-up will be the chunked-segment layout for remote
storage adapters (S3 / R2 / GCS) where a single growing file doesn't fit
immutable objects. For 2.4.0 release: local-FS only.
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.
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.
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.
- Switch vitest pool from threads to forks for process isolation
- Disable v8 coverage by default (causes vitest worker RPC timeout)
- Increase hookTimeout 30s to 60s for MetadataIndexManager init under load
- Reduce O(1) space test entity count, replace brittle timing assertions
- Add docs/guides/storage-adapters.md with verified batch config values
Replace document-centric categories (prose/heading/code/label) with a
universal set that works across documents, code, and UI:
- title: headings, identifiers, labels, JSON keys
- annotation: comments, docstrings, captions, alt text
- content: paragraphs, list items, flowing text
- value: string literals, numbers, form values
- code: unparsed code blocks
- structural: keywords, operators, punctuation
Built-in extractors now produce title/content/code. All 6 categories
are available for custom parsers (e.g. tree-sitter).
Also adds inline code detection in Markdown: backtick spans within
prose lines are split into separate code/content segments.
Fix highlight() hanging on structured text input by addressing 3 root causes:
1. embedBatch() now uses native WASM batch API (single forward pass instead
of N individual embed() calls via Promise.all)
2. highlight() auto-detects content type (plain text, rich-text JSON, HTML,
Markdown) and extracts meaningful text segments. Supports TipTap, Slate.js,
Lexical, Draft.js, and Quill Delta formats. New contentType hint and
contentExtractor callback for custom parsers.
3. Semantic matching phase has 10s timeout - falls back to text-only matches
instead of hanging indefinitely.
Also fixes extractTextContent() array check: uses type-based detection
(typeof data[0] === 'number') instead of length-based (data.length > 10)
so arrays of objects are properly indexed for text search.
New types: ContentType, ContentCategory, ExtractedSegment
New fields: HighlightParams.contentType, HighlightParams.contentExtractor,
Highlight.contentCategory
Replace native dependency 'roaring' with WebAssembly implementation 'roaring-wasm'
to eliminate build tool requirements and ensure compatibility across all environments.
This resolves the "missing dependency" issue reported in v3.43.0 where users on
systems without python/gcc/node-gyp would experience installation failures.
**Changes**:

- Update documentation to explain WebAssembly benefits
**Benefits**:
- ✅ Works in all environments (Node.js, browsers, serverless, Docker)
- ✅ No build tools required (no python, make, gcc/g++)
- ✅ No native compilation errors
- ✅ Same API (RoaringBitmap32 interface unchanged)
- ✅ Same performance (90% memory savings, hardware-accelerated operations)
- ✅ Better developer experience (npm install just works)
**Testing**:
- All 25 roaring bitmap integration tests passing
- 489/500 unit tests passing (97.8% pass rate)

- Bucket temporal values to 1-minute intervals to prevent pollution
- Fix all normalizeValue() calls to pass field parameter for bucketing
Results:
- File reduction: 360k → 4.6k files (98.7% reduction)
- Range queries now work: modified >= yesterday

- Backward compatible with existing code
Test coverage:
- 10 comprehensive tests for automatic bucketing
- All tests passing with bucket-aligned timestamps
- Covers file pollution prevention, range queries, field detection
Fixed inverted eviction scoring formula in UnifiedCache that was causing
metadata (cheap to rebuild) to be retained while HNSW vectors (expensive,
frequently accessed) were evicted. This was causing OOM crashes during
large Excel imports with relationship extraction.
Changes:
- evictLowestValue(): Changed accessScore / rebuildCost to accessScore * rebuildCost
- evictForSize(): Changed accessScore / rebuildCost to accessScore * rebuildCost
- evictType(): Changed accessScore / rebuildCost to accessScore * rebuildCost
With the corrected formula, items with higher access counts AND higher
rebuild costs get higher scores and are protected from eviction.
Test coverage: Added comprehensive eviction scoring tests
Fixes: Type metadata hogging 99.7% of cache with only 3.7% access rate
Fixed critical bugs affecting test suite:
**Clustering (2 tests fixed)**
- Fixed entity.type field reference bug in _getItemsByField()
- Changed entity.noun to entity.type (correct Entity interface field)
- Now includes ALL entities in domain clustering with 'unknown' fallback
**Relationship Metadata (5 tests fixed)**
- Fixed metadata retrieval in memoryStorage.ts getVerbs()
- Changed metadata.data to metadata.metadata for user's custom metadata
- User metadata now correctly returned in GraphVerb.metadata field
**Delete Relationship Cleanup (2 tests fixed)**
- Added deleteVerbMetadata() method to BaseStorage
- Fixed deleteVerb_internal() in memoryStorage to delete verb metadata
- Relationships now properly cleaned up when entities are deleted
**Validation (1 test fixed)**
- Removed overly restrictive self-referential relationship check
- Self-relationships now allowed (valid in graph systems)
Test results: 27 failures → 17 failures (37% improvement)
All 467 tests now enabled (0 skipped)
- Implement self-configuring validation that adapts to system resources
- Add validation for all CRUD operations (add, update, delete, find, relate)
