The relevant question is not how many alerts a system creates. It is whether the exact action was inside the authority that existed before it happened.
Which agent had permission to take this action, on which resource and under which limits?
Was the action allowed, reviewed or denied at the moment it reached the boundary?
Does the signed record still match its hash chain and public verification key?
For payments, did the executor receive a valid one-time grant before funds moved?
A signature proves who issued a decision. A hash chain makes alteration visible. An external timestamp prevents a party from rewriting the entire record later. The resulting receipt can be checked in a browser, offline or by another system.
