Root cause: v5.7.3 cleared write-through cache in brain.flush(), which happens
BETWEEN addMany() and relateMany() in ImportCoordinator - exactly when cache is
needed most.
Changes:
- Remove premature cache.clear() from brain.flush() (brainy.ts:3690-3697)
- Remove unnecessary type cache warming from addMany() (brainy.ts:1859-1877)
- Remove explicit flush() call from ImportCoordinator (ImportCoordinator.ts:1051-1054)
Cache now persists indefinitely, providing safety net for:
- Cloud storage eventual consistency (S3, GCS, Azure, R2)
- Filesystem buffer cache timing
- Type cache warming period (nounTypeCache population)
Cache entries are only removed when explicitly deleted (deleteObjectFromBranch),
not during flush operations. Memory footprint is negligible (<10MB for 100k entities).
This is the correct, ultra-simple fix that v5.7.2 and v5.7.3 were attempting to achieve.
