fix: update() field asymmetry causing index corruption
...
CRITICAL: Fixed metadata index corruption on update() operations where
removalMetadata only contained custom metadata + type, while entityForIndexing
contained ALL indexed fields. This caused 7 fields to accumulate on every
update, eventually making queries return 0 results.
- Fix removalMetadata to include all indexed fields (src/brainy.ts)
- Add validateIndexConsistency() and getIndexStats() public APIs
- Add auto-corruption detection and repair on startup
- Add getOrAssignSync() for EntityIdMapper persistence
- Add comprehensive regression tests

fix: v4.8.1 critical bug fixes for update() and clustering
...
- Fix update() method saving data as '_data' instead of 'data'
- Fix update() passing wrong entity structure to metadata index
- Add guard against undefined IDs in analyzeKey() for clustering
- Fix EntityIdMapper to read from top-level metadata in v4.8.0
- Fix PatternSignal tests to use NounType.Measurement
- Update test expectations for v4.8.0 entity structure
Fixes augmentations-simplified.test.ts (all 25 tests passing)
Fixes neural-simplified clustering (32/33 tests passing)
Overall: 98.3% test pass rate (988/997 tests)

feat(v4.0.0): Complete metadata/vector separation architecture with Azure support
...
This commit completes the core v4.0.0 architecture changes for billion-scale
performance with metadata/vector separation. NO RELEASE YET - remaining optimizations
and testing required before production release.
## Core v4.0.0 Architecture Changes
### Type System Updates
- Fixed all TypeScript compilation errors (zero errors achieved)
- Updated HNSWNoun/HNSWVerb to separate core fields from metadata
- Implemented HNSWNounWithMetadata/HNSWVerbWithMetadata for API boundaries
- Added required 'noun' field to NounMetadata for semantic structure
- Renamed verb.type to verb.verb for consistency
### Storage Adapter Updates
**All adapters updated for v4.0.0 two-file storage pattern:**
- memoryStorage: Proper metadata/vector separation
- fileSystemStorage: Two-file pattern with sharding
- opfsStorage: Browser persistent storage updated
- s3CompatibleStorage: AWS/MinIO/DigitalOcean support
- r2Storage: Cloudflare R2 optimization
- gcsStorage: Google Cloud with ADC support
- **azureBlobStorage: NEW - Full Azure Blob Storage support**
### Storage Features
- BaseStorage: Internal vs public method separation (_getNoun vs getNoun)
- Two-file storage: Vectors in one file, metadata in another
- Change tracking: getChangesSince return type updated
- Pagination: getNounsWithPagination returns WithMetadata types
### Azure Blob Storage Integration (NEW)
- Native @azure/storage-blob SDK integration
- Four authentication methods:
* DefaultAzureCredential (Managed Identity) - recommended
* Connection String - simplest setup
* Account Name + Key - traditional auth
* SAS Token - delegated access
- High-volume mode with write buffering
- Adaptive backpressure for throttling
- UUID-based sharding for billion-scale
- Full HNSW support with graph persistence
### Utility Updates
- EmbeddingManager: Updated to accept Record<string, unknown>
- LSMTree: Wrapped data in NounMetadata structure with 'noun' field
- EntityIdMapper: Fixed nested metadata.data structure access
- MetadataIndex: Fixed field type inference integration
- PeriodicCleanup: Updated for new metadata structure
### Core API Updates
- Brainy: Updated verb property access from v.type to v.verb
- ConfigAPI: Fixed NounMetadata access patterns
- DataAPI: Updated metadata handling
### Documentation Updates
- CREATING-AUGMENTATIONS.md: v4.0.0 breaking changes guide
- DEVELOPER-GUIDE.md: Migration checklist and examples
- COMPLETE-REFERENCE.md: v4.0.0 architecture improvements
- **finite-type-system.md: NEW - Revolutionary type system benefits**
### Build & Dependencies
- Zero TypeScript compilation errors
- Added @azure/storage-blob and @azure/identity
- 591 tests passing (23 timeout in long-running neural tests)
## What's NOT in This Release
This is a work-in-progress commit. Before v4.0.0 release we need:
- Storage adapter optimizations (batch operations, compression)
- Azure blob tier management (Hot/Cool/Archive)
- Cost optimization implementations
- Additional performance testing at billion-scale
- Migration guides for v3.x users
## Testing
- Clean build: ✅
- Type checking: ✅ (zero errors)
- Test suite: ✅ (591/614 passing, timeouts in neural tests only)

fix: correct TypeScript types for roaring bitmap API
...
- Change EntityIdMapper to use StorageAdapter interface instead of BaseStorage
- Use RoaringBitmap32.orMany() for multiple bitmap OR operations
- Use manual reduction for AND operations (no andMany available)
- Fixes TypeScript compilation errors

fix: correct import paths for TypeScript compilation
...
- Add .js extension to entityIdMapper baseStorage import
- Change roaring imports from subpath to main package export
- Use import { RoaringBitmap32 } from 'roaring' for ESM compatibility

feat: optimize metadata indexing with roaring bitmaps for 90% memory reduction
...
Replace JavaScript Sets with hardware-accelerated RoaringBitmap32 for metadata indexes.
Key improvements:
- 1.4x average speedup, up to 3.3x on 10K entities
- 90% memory reduction (40 bytes/UUID → 4 bytes/int)
- Hardware-accelerated multi-field intersection via SIMD (AVX2/SSE4.2)
- EntityIdMapper for bidirectional UUID ↔ integer mapping
- Portable serialization format
Benchmark results (1,000 queries):
- 10K entities: 3.74ms → 1.14ms (3.3x faster, 90% memory savings)
- 100K entities: 2.60ms → 1.78ms (1.5x faster, 88% memory savings)
Implementation:
- Add EntityIdMapper class for UUID/int mapping with persistence
- Modify ChunkData to use Map<string, RoaringBitmap32>
- Add getIdsForMultipleFields() for fast bitmap intersection
- Include comprehensive tests (25 tests passing)
- Add performance benchmark comparing Set vs Roaring
Technical details:
- roaring@2.4.0 dependency
- Maintains backward compatibility
- All queries still return UUID strings
- Automatic persistence via storage adapter
