Two production correctness defects fixed together so consumers can land
one upgrade.
BR-FIND-WHERE-ZERO — find() returned [] and stats() reported 0 entities
for any workspace whose data was written after the 7.20.0 column-store
refactor. Root cause: getStats() and the getIds() fallback still read
from the deleted sparse-index path. Separately, BaseStorage.getNounType()
was hardcoded to return 'thing', poisoning type-statistics.json with
every noun attributed to that bucket.
- MetadataIndex.getStats() reads from ColumnStore + idMapper.
- MetadataIndex.getIdsFromChunks() throws BrainyError(FIELD_NOT_INDEXED)
when neither store has the field. getIdsForFilter() catches per
clause, logs once, returns [].
- BaseStorage.nounTypeByIdCache populated in saveNounMetadata_internal
and consumed in saveNoun_internal. flushCounts() now persists the
Uint32Array counters too, so readers see fresh per-type counts.
- Self-heal at init: loadTypeStatistics() auto-rebuilds when the
poisoned signature is detected. rebuildTypeCounts() is now public for
use from `brainy inspect repair`.
- Dead state removed: dirtyChunks, dirtySparseIndices,
flushDirtyMetadata().
BR-DEFENSIVE-INTERFACE — 7.21.0 called supportsMultiProcessLocking()
unconditionally, crashing on older Cortex storage adapters that predate
the method. New hasStorageMethod(name) helper gates every new-method
call site. Older adapter triggers a one-line warning at init pointing
at the recommended plugin version.
Tests:
- new tests/integration/find-where-zero.test.ts (7 cases)
- new tests/integration/cortex-compat.test.ts (5 cases)
- multi-process-safety.test.ts updated to enforce correct counts
- 1329/1329 unit + 24/24 new integration tests passing
