Previously metadataIndex.rebuild() called idMapper.clear() which reset nextId to 1 and renumbered every UUID by re-insertion order. Any consumer that had persisted int-keyed data against the old map was silently invalidated — and 2.4.0's vector mmap store (#20), graph link compression (#21), and column-store JS↔native interchange all need persisted int indices that survive a rebuild. Remove the unconditional clear() in rebuild(). The rebuild already re-iterates every entity via idMapper.getOrAssign(uuid), which returns the existing int unchanged for known UUIDs. Stale UUID→int entries for entities no longer in storage persist as harmless memory overhead; a dedicated prune step can be added if it ever matters. clearAllIndexData() — the explicit nuclear recovery path — keeps its existing idMapper.clear() call (renumbering is intentional there), and now logs a prodLog.warn making it explicit that any persisted int-keyed data is invalidated and must be rebuilt from canonical sources. Strengthened the EntityIdMapper class JSDoc to document the stability guarantee as a contract — append-only getOrAssign, monotonic nextId, remove() leaves permanent holes, rebuild() never renumbers, only clear() does. Added tests/regression/entity-id-mapper-stability.test.ts pinning down the five-point contract: (1) single-rebuild stability; (2) many-rebuild stability; (3) post-rebuild adds get fresh monotonic ints; (4) removes leave permanent holes — new entities never recycle; (5) clearAllIndexData() explicitly renumbers (the documented destructive path). Foundation for 2.4.0 #2-#4. Full test suite (62 files, 1417 tests) green. |
