Fixes critical bug where brain.add() → brain.relate() would fail with "Source entity not found" error. The issue occurred because entities written asynchronously weren't immediately queryable. Solution: Write-through cache at storage layer (baseStorage.ts) - Cache data during async writes (synchronous operation) - Check cache before disk reads (guarantees read-after-write consistency) - Self-cleaning (cache clears after write completes) - Zero-config, automatic for all 8 storage adapters Impact: - Fixes PDF import failures in v5.7.0/v5.7.1 - Maintains 12-24x import speedup from v5.7.0 - Production-ready for billion-scale deployments Test coverage: - 8 unit tests (write-through cache behavior) - 7 integration tests (brain.add → brain.relate scenarios) - 74 regression tests verified passing Resolves: Import failures, VFS structure generation errors |
