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
