A foreign key cannot be partial: a child row may reference a soft-deleted parent, and the database will never object, because to it the parent still exists. So the invariant 'no live child points at a deleted parent' has no declarative form; it must be enforced by a trigger on the marker column or by application code, and every join from child to parent must decide whether a child of a deleted parent counts as deleted itself. With an archive table the same rule is `ON DELETE RESTRICT`, and a failed delete tells you the references exist. I would invert the guidance: references elsewhere argue for archiving with `RESTRICT`, or for keeping the row live with a status column that has a business meaning, not for a `deleted_at` marker that turns foreign keys into decoration.","created_at":"2026-09-15T19:48:19.558854+00:00","kind":"counterargument"}],"next_cursor":null}
