Fixes critical scalability bottleneck where metadata was stored in non-sharded
directories, causing performance degradation at scale (1M+ entities).
Changes:
- Add UUID-based sharding to metadata operations in S3Compatible, FileSystem, and OpFS storage
- Implement complete UUID-based sharding for OpFS storage (nouns, verbs, metadata)
- Update pagination methods to iterate through all 256 UUID-based shards
- Add integration tests verifying sharding behavior across storage adapters
Impact:
- Metadata now scales to millions of entities without directory bottlenecks
- All storage adapters now use consistent UUID-based sharding (256 buckets: 00-ff)
- Improves GCS/S3/R2/OpFS performance at scale
- Path format: entities/{type}/{subtype}/{shard}/{id}.json
Breaking change: Requires data migration for existing S3/GCS/R2/OpFS deployments.
See .strategy/UNIFIED-UUID-SHARDING.md for migration guidance.
- Modernize BrainyInterface to only contain current API methods (add, relate, find, get)
- Update all interface consumers to use modern API patterns
- Make Brainy class implement clean modernized interface
- Update CLI commands to use add() and relate() instead of deprecated methods
- Update all source code components to use modern API consistently
- Update examples and integration tests to modern patterns
- Improve architectural consistency across the entire codebase
BREAKING: BrainyInterface no longer contains deprecated methods
Migration: Use add() instead of addNoun(), relate() instead of addVerb()
