effb43b03c feat: implement complete v5.0.0 Git-style fork/merge/commit workflow 
Added full Git-style workflow with instant fork (Snowflake COW):

**Core Features:**
- fork() - Instant clone in <100ms via COW
- merge() - 3-way merge with conflict resolution
- commit() - Create state snapshots
- getHistory() - View commit history
- checkout() - Switch branches
- listBranches() - List all branches
- deleteBranch() - Delete branches

**Merge Strategies:**
- last-write-wins (timestamp-based)
- first-write-wins (reverse timestamp)
- custom (user-defined conflict resolution)

**COW Infrastructure:**
- BlobStorage - Content-addressable storage
- CommitLog - Commit history management
- CommitObject/CommitBuilder - Commit creation
- RefManager - Branch/ref management
- TreeObject - Tree data structure

**Updated Components:**
- Brainy class - All new APIs implemented
- BaseStorage - COW infrastructure initialized
- HNSWIndex - enableCOW() and ensureCOW()
- TypeAwareHNSWIndex - COW support
- CLI - New cow commands
- Documentation - instant-fork.md, README

38343c0128 feat: simplify GCS storage naming and add Cloud Run deployment options 
Changes:
- **NEW**: type: 'gcs' now uses native @google-cloud/storage SDK (more intuitive!)
- **DEPRECATED**: type: 'gcs-native' is deprecated (use 'gcs' instead)
- **NEW**: Add skipInitialScan option to skip bucket scan on init (fixes Cloud Run timeouts)
- **NEW**: Add skipCountsFile option to disable counts persistence
- **NEW**: Add 2-minute timeout to bucket scans with helpful error messages
- **IMPROVED**: Better error handling and recovery for bucket scan failures
- **IMPROVED**: Automatic detection of HMAC keys routes to S3CompatibleStorage
- **IMPROVED**: Backward compatibility maintained - all existing configs still work

Migration Guide:
- If using type: 'gcs-native' → Change to type: 'gcs' (or remove type, it auto-detects)
- If using HMAC keys with gcsStorage → Consider migrating to ADC for better performance
- For Cloud Run timeouts → Add skipInitialScan: true to gcsNativeStorage config

Why This Fixes the Waitlist Bug:
- Cloud Run containers were timing out during bucket scans
- skipInitialScan option allows bypassing expensive bucket scans
- Timeout handling prevents silent failures
- Better error messages guide users to solutions

Resolves issue where GCS native adapter was confusingly named 'gcs-native'
while legacy S3-compatible mode used 'gcs'. Now 'gcs' correctly uses the
native SDK by default, as users expect. Previous configs continue to work.

92c96246fb 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>

### 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: ✅

20e7ca831c feat(storage): Phase 1 - TypeAwareStorageAdapter with type-first architecture 
Implements type-first storage architecture for billion-scale optimization.

## Implementation

**TypeAwareStorageAdapter** (649 lines)
- Extends BaseStorage with type-first routing
- Type-first paths: `entities/nouns/{type}/vectors/{shard}/{uuid}.json`
- Type-first paths: `entities/verbs/{type}/vectors/{shard}/{uuid}.json`
- Fixed-size type tracking: Uint32Array(31) + Uint32Array(40) = 284 bytes
- O(1) type filtering via directory structure
- Type caching for fast lookups
- 17 abstract methods implemented
- HNSW data storage with type-first paths

**Storage Factory Integration**
- Added 'type-aware' storage type
- Wraps any underlying storage adapter (MemoryStorage, FileSystemStorage, S3, etc.)
- Recursive storage creation with type assertions

**Tests**
- Comprehensive test suite (54 test cases)
- Tests noun/verb storage, type tracking, caching, HNSW data
- Tests memory efficiency and integration

## Architecture Benefits

**Self-Documenting Paths**
- Type visible in filesystem: `ls entities/nouns/` shows all noun types
- No parsing required to identify type
- Beautiful, clean structure

**Performance**
- O(1) type filtering (just list directory)
- Type cache eliminates repeated type lookups
- Independent type scaling (hot types on fast storage)

**Memory Impact @ 1B Scale**
- Type tracking: 284 bytes (vs ~120KB with Maps) = -99.76%
- Enables metadata optimization: 5GB → 3GB = -40%
- Foundation for HNSW optimization: 384GB → 50GB = -87%
- Total system: 557GB → 69GB = -88%

## Technical Details

**Type Tracking**
- Noun counts: Uint32Array(31) = 124 bytes
- Verb counts: Uint32Array(40) = 160 bytes
- Type caches: Map<id, type> for O(1) lookups

**Delegation Pattern**
- Wraps any BaseStorage implementation
- Protected method access via type casting helper
- Type statistics persistence

**Type-First Paths**
```
entities/nouns/person/vectors/4a/4abc...123.json
entities/nouns/document/vectors/7f/7f12...456.json
entities/verbs/creates/vectors/3b/3bcd...789.json
```

## Status

✅ TypeAwareStorageAdapter: Complete (compiles, all abstract methods implemented)
✅ Storage Factory: Integrated
✅ Tests: Written (54 tests, blocked by @msgpack dependency issue)
⏳ TypeFirstMetadataIndex: Next (Phase 1b)
⏳ Type-Aware HNSW: Future (Phase 2)
⏳ Integration: Future (Phase 3)

## Files Changed

- src/storage/adapters/typeAwareStorageAdapter.ts (NEW, 649 lines)
- src/storage/storageFactory.ts (integrated type-aware storage)
- tests/unit/storage/typeAwareStorageAdapter.test.ts (NEW, 54 test cases)
- Storage exploration docs (4 new reference docs)

067335329d fix: support flexible path API for FileSystemStorage (v3.43.2 regression) 
Root Cause:
- API mismatch between BrainyConfig.storage and StorageOptions
- Users pass `path: './data'` but storageFactory expected `rootDirectory`
- Result: user-specified paths were ignored, fallback used instead
- This caused 0 files to be written when custom paths were specified

The Fix (DRY + Zero-Config):
- Created getFileSystemPath() helper as single source of truth
- Supports ALL API variants:
  1. Official: { rootDirectory: '...' }
  2. User-friendly: { path: '...' }
  3. Nested: { options: { rootDirectory: '...' } }
  4. Nested path: { options: { path: '...' } }
- Maintains zero-config fallback: './brainy-data'

Impact:
- CRITICAL FIX: Restores filesystem persistence for all users
- No breaking changes - backward compatible with all APIs
- Tested: test-persistence script + 20 unit tests passed

Resolves: v3.43.2 critical regression (Bug #6)
