fix: exclude __words__ keyword index from corruption detection and getStats()
...
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.

feat: ID-first storage architecture + remove memory-unsafe APIs (v6.0.0)
...
BREAKING CHANGES:
**ID-First Storage Paths**
- Direct O(1) entity access without type lookups
- Before: entities/nouns/{TYPE}/metadata/{SHARD}/{ID}.json
- After: entities/nouns/{SHARD}/{ID}/metadata.json
- Migration handled automatically on first init()
**Removed Memory-Unsafe APIs**
- Removed brain.merge() - loaded all entities into memory
- Removed brain.diff() - loaded all entities into memory
- Removed brain.data().backup() - loaded all entities into memory
- Removed brain.data().restore() - depended on backup()
- Removed CLI commands: backup, restore, cow merge
**Migration Paths**
- merge() → Use checkout() or manually copy entities with pagination
- diff() → Use asOf() with manual paginated comparison
- backup() → Use fork() for instant COW snapshots
- restore() → Use checkout() to switch to snapshot branch
Core Improvements:
- ✅ All 8 storage adapters properly call super.init()
- ✅ GraphAdjacencyIndex integration in BaseStorage.init()
- ✅ Fixed ID-first path bugs (vector.json → vectors.json)
- ✅ Fixed MemoryStorage.initializeCounts() for ID-first paths
- ✅ New VFS APIs: du(), access(), find()
- ✅ Comprehensive documentation with migration guides
Storage Adapters Fixed:
- MemoryStorage, FileSystemStorage, AzureBlobStorage
- GCSStorage, R2Storage, S3CompatibleStorage
- OPFSStorage, HistoricalStorageAdapter

feat: COW always-on architecture + cloud storage clear() fix (v5.11.0)
...
Major architectural improvements and critical bug fixes:
## COW Always-On Architecture
- Removed cowEnabled flag from BaseStorage (COW cannot be disabled)
- Eliminated marker file system (checkClearMarker, createClearMarker)
- Simplified all code paths to assume COW is always enabled
- COW automatically re-initializes after clear() operations
## Critical Bug Fix: Cloud Storage clear()
- Fixed GCS clear() using correct paths (branches/ instead of entities/nouns/)
- Fixed S3Compatible clear() path structure
- Fixed R2 clear() implementation
- Fixed Azure, FileSystem, OPFS, Memory clear() COW flag handling
- clear() now deletes: branches/, _cow/, _system/
- Result: Cloud buckets can now be fully cleared (previously impossible)
## Container Memory Detection
- Auto-detect Docker/K8s/Cloud Run memory limits (cgroup v1/v2)
- Smart memory allocation (75% graph data, 25% query operations)
- Environment variable support (CLOUD_RUN_MEMORY, MEMORY_LIMIT)
- Production-grade containerized deployment support
## CommitLog streamHistory Feature
- Added streamable commit history with pagination
- Efficient memory usage for large commit histories
- Support for branch filtering and time ranges
## Comprehensive Storage Documentation
- Complete v5.11.0 file structure reference
- Detailed path construction algorithms
- 8 common storage scenarios with examples
- Type-first storage, sharding, COW architecture explained
- Public docs: docs/architecture/data-storage-architecture.md (1063 lines)
## Files Modified (14 files)
- All 8 storage adapters (GCS, S3, R2, Azure, FS, OPFS, Memory, Historical)
- BaseStorage core architecture
- CommitLog with streaming
- Brainy memory configuration
- Parameter validation with container detection
- Storage architecture documentation
## Breaking Changes
NONE - COW was already enabled by default. This removes the ability to disable it.
## Migration
No action required. Upgrade and clear() will work correctly on cloud storage.
## Impact
- Users can now clear cloud storage buckets completely
- No more corrupted buckets after clear() operations
- Container deployments automatically optimize memory allocation
- COW is mandatory and always enabled (safer, simpler)
v5.11.0 - Production ready

feat: implement always-adaptive caching with getCacheStats monitoring
...
Replaces lazy mode concept with always-adaptive caching strategy:
- Rename getLazyModeStats() → getCacheStats() with enhanced metrics
- Change lazyModeEnabled boolean → cachingStrategy enum ('preloaded' | 'on-demand')
- Update preloading threshold from 30% to 80% for better cache utilization
- Add comprehensive production monitoring and diagnostics
- Add memory detection for containers (Docker/K8s cgroups v1/v2)
- Add adaptive memory sizing from 2GB to 128GB+ systems
Breaking changes: None (backward compatible, deprecated lazy option ignored)
New APIs:
- getCacheStats(): Comprehensive cache performance statistics
- cachingStrategy field: Transparent strategy reporting
- Enhanced fairness metrics and memory pressure monitoring
Documentation:
- Add migration guide for v3.36.0
- Add operations/capacity-planning.md for enterprise deployments
- Update all examples and troubleshooting guides
- Rename monitor-lazy-mode.ts → monitor-cache-performance.ts

fix: move metadata routing to base class, fix GCS/S3 system key crashes
...
Critical fix for GCS/S3 native storage adapters crashing on metadata index keys.
Problem:
- GCS and S3 adapters crashed with "Invalid UUID format" errors
- System keys like __metadata_field_index__status are NOT UUIDs
- Adapters incorrectly tried to shard all metadata keys as UUIDs
Solution:
- Move sharding/routing logic from adapters to BaseStorage class
- Add analyzeKey() method to detect system keys vs entity UUIDs
- System keys route to _system/ directory (no sharding)
- Entity UUIDs route to sharded directories (256 shards)
- All adapters now implement 4 primitive operations:
* writeObjectToPath(path, data)
* readObjectFromPath(path)
* deleteObjectFromPath(path)
* listObjectsUnderPath(prefix)
Benefits:
- Impossible for future adapters to repeat this mistake
- Zero breaking changes, full backward compatibility
- No data migration required
- Cleaner architecture with better separation of concerns
Updated adapters: GcsStorage, S3CompatibleStorage, OPFSStorage,
FileSystemStorage, MemoryStorage
Added: docs/architecture/data-storage-architecture.md
Updated: README.md with architecture docs link
