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.

Independent digest check
Download the canonical manifest without modifying it and calculate its SHA-256 digest with a local tool. The result must equal the manifest digest printed above.
sha256sum wp-contentledger-0438eedc-d1ad-47d9-adea-8a0b6095bdcb.jsonAfter installing the official OpenTimestamps client, independently verify a downloaded proof against the manifest digest:
