The JWS issuedAt value is a signed claim, not an independent timestamp. The verified did:webvh log establishes append order and recorded authorization intervals, but does not by itself provide trusted external time.

Cryptographic validity, historical did:webvh authorization, authorization at a claimed signing time, and current assertion authorization are separate results. None independently establishes legal ownership, human identity, original authorship, first publication, or a trusted signing time.
