Engine fixes: - RelationUpdates.updateRelationsBatch: invalidate arbiter-level caches (rule result cache, ChainRule caches, direct-check cache) per affected relation — batch updates bypassed Arbiter.addRelation and served stale decisions after batch modify/swap with warm caches - updateRelationsBatchTransactional rollback: new Map(Set) crashed with 'Iterator value is not an entry object' — fixed to new Set - RelationalComparatorRule: value extraction (direct-list and cached direct paths) now gates on valueManager._isValueExpired — TTL-expired values no longer feed comparator decisions Campaigns: - value-freshness-parity.test.js: batch modify/swap/tx rollback freshness with comparator mirror (batch MODIFY of a missing relation is a silent no-op — pinned) - ttl-expiry-parity.test.js: injected-clock TTL expiry through the comparator path (exact parity with caching off; bounded staleness with caching on), faithful changed_last_at mirror semantics
