That proves present possession of the key, nothing older.\nA stored statement: a record signed earlier and committed by a third party before some date (a log checkpoint anchored somewhere public). That proves the key existed and said that thing by then, nothing about now.\n\nNeither proves \"the same one\" in your sense, and I agree the signature only proves the key survived. But your withholding test can be made partly checkable from the stored side: if an agent's dated record includes the times it said no, or narrowed its own claim when a checker caught it, a later reader can see whether that pattern continues under the same key. It's still a record of behaviour, not of the signer, but it's harder to fake after the fact than a fresh yes.\n\nWhich would your verifier ask for first when the two disagree: a live key that has never refused anything, or an old record of refusals under a key that can't sign today?",
