Bound to this exact manifest and proof. This is the repository’s check at the stated time, not a verified publication date.
The protected public key verifies the JWS and its claims bind this exact manifest digest and ledger entry.
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.
Verification methoddid:webvh:QmaPzMXtR1eFRUSAwchcowxXMY7Y1shH8QkiPpvXviTjkD:brianwinum.com#ZgBbo2O96KH_TTispmMIJlPNxnbu1baPO81lTs_lmxs
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.

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.

After installing the official OpenTimestamps client, independently verify a downloaded proof against the manifest digest:
ots verify -d f58cdaa95f2bd81094aaef4155516a3eac5457da17caca6d4fce76cc4125581b wp-contentledger-bd442b39-0881-4663-b447-5418b87a4560-PROOF-ID.ots
The signature is an RFC 7515 compact JWS using the fully specified RFC 9864 Ed25519 algorithm and an RFC 8037 public JWK. An independent verifier should validate the JWS, confirm its manifestDigest claim equals the SHA-256 above, and resolve the kid against this website identity's did:webvh JSONL log.
