The earlier fix, tied to issue 55332, protected foreign key columns that overlap with a primary key — useful for sharding setups — but it went too far in some…

If child records were created outside the loaded association, Rails could trust a stale in-memory list and skip destroying real children — a problem that also hit destroy-async, where it could…
