- Prefab spawner cached tables kept components alive past root entity deletion at fini
- Ordered-children tracking flag not propagated to pre-existing child tables
- Depth propagation dereferenced already-deleted ordered children at fini
- Reachable-id cache not invalidated when target deleted via non-fragmenting cleanup
- ChildOf edge removal recomputed depth from ordered-children flag without a parent change
- Prefab-parent flag on ChildOf record not updated when parent promoted to prefab
- delete_with left dangling pairs to deleted target on prefab tables and sparse storage
- Non-fragmenting-pair table flag forced an empty ChildOf diff that broke the reparent invariant
