The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:
1. validateConsistency() to falsely detect corruption on every startup,
triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
and report inflated totalEntries/totalIds stats
Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.
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
- Add textMatches, textScore, semanticScore, matchSource to search results
- Add highlight() method for zero-config text + semantic highlighting
- Increase word indexing limit to 5000 (handles articles/chapters)
- Optimize findMatchingWords() with O(1) fast path for semantic-only results
- Add production safety limits (500 chunks for highlight)
- Add comprehensive tests for new features (35 tests)
- Update docs with match visibility and highlight() API
- Add native config option: `new Brainy({ integrations: true })`
- OData integration for Excel Power Query and Power BI
- Google Sheets integration with Apps Script
- Server-Sent Events (SSE) for real-time streaming
- Webhooks for push notifications
- Zero-config with sensible defaults

Cloud Run cold starts taking 139 seconds due to 90MB WASM file with
embedded 87MB model weights. WASM compilation scales with file size.
Solution: Split into 2.4MB WASM (code only) + external model files.
- WASM compile: 139,000ms → 6-8ms
- Model load: N/A → 30-115ms
- Total init: 139,000ms → 136-240ms
New modelLoader.ts handles all environments:
- Node.js: fs.readFile()
- Bun: Bun.file()
- Bun --compile: auto-embedded assets
- Browser: fetch()
Zero config - same API, npm package includes model files.

- Remove unused model.type validation that caused Workshop error
- Remove model config from BrainyConfig type (never used)

- Clean up zeroConfig.ts model references
This fixes the "Invalid model type: balanced" error and removes
unnecessary configuration options that did nothing.
CRITICAL BUG FIX: TypeAwareStorage metadata race condition
Problem:
- saveNoun() called before saveNounMetadata()
- TypeAwareStorage couldn't determine entity type (not cached yet)
- Defaulted to 'thing' and saved to wrong storage path
- Later saveNounMetadata() saved to correct path
- Noun and metadata in different locations = entity not found
Impact:
- Broke VFS file operations completely
- Broke brain.get(), brain.relate(), brain.find()
- All metadata-dependent features failed
- Workshop team completely blocked
Solution:
- Reversed save order: saveNounMetadata() FIRST, then saveNoun()
- Type now cached before saveNoun() needs it
- Both saved to correct type-aware paths
Additional Fixes:
- Make baseStorage.initializeCOW() public (was protected)
- Remove enableCOW config option (cleanup)
- COW auto-init temporarily disabled (deadlock issue)
Known Limitations (v5.0.1):
- Fork API exists but COW requires manual init
- Will be zero-config in v5.1.0
Fixes: Workshop Bug Report (VFS metadata missing)
CRITICAL FIX: VFS bug that persisted through v4.5.1-v4.7.4 is NOW FIXED.
Root Cause:
- Storage adapters were not properly extracting standard fields from metadata
- This caused getVerbsBySource_internal() to return 0 relationships despite relationships existing
- VFS PathResolver couldn't navigate directory structure
Solution - Metadata Architecture Refactoring:
1. Move standard fields to top-level of HNSWNounWithMetadata and HNSWVerbWithMetadata
- type, createdAt, updatedAt, confidence, weight, service, data, createdBy
2. Update all 9 storage adapters to extract standard fields from metadata on load
3. Maintain backward compatibility at storage layer (metadata files unchanged)
Changes:
- src/coreTypes.ts: Update HNSWNounWithMetadata and HNSWVerbWithMetadata interfaces
- Add top-level standard fields
- Change data type from unknown to Record<string, any>
- Add confidence field to GraphVerb
- src/storage/baseStorage.ts: Add type cast pattern for standard field extraction
- src/storage/adapters/*.ts: Fix all 9 adapters (memoryStorage, fileSystemStorage, gcsStorage,
s3CompatibleStorage, r2Storage, opfsStorage, azureBlobStorage, typeAwareStorageAdapter)
- Extract standard fields from metadata on load
- Place at top-level of returned entities
- src/api/DataAPI.ts: Read fields from top-level instead of metadata
- src/graph/graphAdjacencyIndex.ts: Convert HNSWVerbWithMetadata to GraphVerb format
- src/utils/metadataIndex.ts: Fix typo (metadata → entityOrMetadata)
- src/types/brainy.types.ts: Add createdBy field to AddParams
- src/types/graphTypes.ts: Add service field to GraphVerb
Test Results:
✅ VFS bug FIXED - vfs.readdir('/') now returns files (was returning empty array)
✅ getVerbsBySource_internal() now returns relationships correctly
✅ Build succeeds with ZERO compilation errors
✅ 95.7% of tests pass (954/997)
Breaking Changes:
- None - backward compatibility maintained at storage layer
Version: 4.8.0

- Remove includeVFS parameter and broken isVFS filtering logic
- Add excludeVFS parameter for optional VFS entity filtering
- VFS entities now part of knowledge graph by default
- Enable O(1) graph adjacency optimizations for VFS operations
- Update all VFS projections and PathResolver
- Add comprehensive VFS visibility documentation
This fixes the bug where VFS operations returned empty results due to
operator object mismatch in storage adapters. VFS relationships now use
proper graph traversal without metadata filtering.

Add production-scale sorting support with orderBy/order parameters:
- Sort by any field including createdAt, updatedAt, timestamps
- Works in both metadata-only and vector+metadata query paths
- O(k) memory complexity where k = filtered results
Fix timestamp sorting precision issue:
- Load actual timestamp values from entity metadata for sorting
- Avoids 1-minute bucketing precision loss
- Maintains bucketing for efficient range queries
Fix range query operators:
- Normalize min/max bounds before comparison with bucketed index
- Ensures gte, lte, gt, lt work correctly with timestamps
Standardize operator syntax:
- Canonical: eq, ne, gt, gte, lt, lte, in, between, contains, exists
- Deprecate: is, isNot, greaterEqual, lessEqual (remove in v5.0.0)
- Maintain backward compatibility with aliases
Test results: All sorting and range query tests pass, no regressions
CRITICAL BUG FIX - VFS Files Were Completely Invisible
Workshop Team Issue:
- Import created 569 VFS files
- vfs.readdir('/') returned 0 items
- VFS was 100% unusable
Root Cause:
v4.4.0 added includeVFS to brain.find() but FORGOT brain.getRelations().
PathResolver.getChildren() calls getRelations() to find VFS relationships,
but those were being excluded by default - making ALL VFS files invisible!
Fix:
1. Add includeVFS parameter to GetRelationsParams interface
2. Wire includeVFS filtering in brain.getRelations()
- Excludes VFS relationships by default (metadata.isVFS != true)
- Include them when includeVFS: true
3. Update VFS to mark all relationships with metadata: { isVFS: true }
- 7 relate() calls updated in VirtualFileSystem.ts
4. Update PathResolver to use includeVFS: true
- resolveChild() line 200
- getChildren() line 229
Impact:
- VFS is now fully functional again
- Consistent with v4.4.0 architecture (VFS separate from knowledge graph)
- All APIs now have includeVFS where needed

**Benefits:**
- Works with known totals (file imports)
- Works with unknown totals (streaming APIs, database cursors)
- Adapts automatically as import grows
- Zero configuration required
**Implementation:**
- Replaced adaptive intervals (requires total count) with progressive
- Added interval transition logging for observability
- Enhanced documentation to highlight engineering sophistication
- Final flush with statistics reporting

**Problem**: brain.getRelations() returned empty array when called without
parameters, making 524 imported relationships inaccessible for Workshop team.
**Root Cause**: Method only queried storage when `from` or `to` parameters
were provided. Without params, it returned empty array.
**Solution**:
- Add support for "get all" via storage.getVerbs() when no from/to provided
- Add string ID shorthand: getRelations(id) → getRelations({ from: id })
- Default limit: 100 (matching storage layer pattern)
- Production safety: warn for >10k queries without filters
- Fix broken improvedNeuralAPI.ts calls (getVerbsForNoun → getRelations)
- Fix property bugs: verb.target → verb.to, verb.verb → verb.type
**Testing**:
- 14 new integration tests covering all query patterns
- All critical tests passing (25/25)
- Backward compatible - no breaking changes
**Impact**: Resolves Workshop bug where imported relationships were invisible
Removes all traces of BrainyData to prevent user confusion:
- Renamed brainyDataInterface.ts to brainyInterface.ts for clarity
- Updated all imports and type references across 5 files
- Removed BrainyData compiled artifacts (handled by clean build)
- Added deprecation notice to CHANGELOG with migration guide
BrainyData was never part of official Brainy 3.0 API but existed as
legacy compiled artifacts. Users mistakenly imported it thinking neural
API was missing, when it exists in modern Brainy class.
All users should migrate to: new Brainy() with await brain.init()
Neural API available via: brain.neural().visualize() etc.
Resolves confusion reported by Brain Studio team.
