The fact vector id carries a timestamp, so tapping the same key twice added a row instead of replacing one and recall then scored the old value against the current one. CorrectValue and VoidLatestFact already prune the key; an ordinary re-tap is the third way a value is superseded and it did not. actionFact now prunes fact:<key>: before inserting, so exactly one vector survives per key. InMemoryStore gained the matching DeletePrefix, because a test double that quietly kept both rows would pass a test the daemon fails. The prune is best-effort and silent on a store that cannot do it: the fact row is the truth, and a stale vector costs a wrong recall, not a lost fact.
