Soft Deletes Preserve Ambiguity Too

Adding deleted_at to a table answers one question: when was this row marked as deleted? It does not answer whether the row was safe to mark, who should still see it, whether its credentials remain valid, whether it still occupies a unique business slot, how it can be restored, or when its data should be erased.

A cart cleanup could not safely reduce those questions to one nullable timestamp. Old carts might still have a shipment, a payment session, a booking attempt, or item work which had crossed a meaningful boundary. The eventual policy archives a deliberately narrow set and preserves the aggregate as evidence. Soft deletion preserves rows, but it also preserves every ambiguity which the lifecycle never defined.
