The SHA-256 digest was recalculated from the downloaded manifest bytes.
The manifest matches the deterministic ContentLedger RFC 8785 serialization profile.
Internet Archive workflow status: Unverified. Origin evidence remains independently verifiable.
Any previous-manifest digest resolves to an earlier sealed record in this ledger.
Legacy records do not receive retroactive content-digest claims.
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.

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 994429e8813ecf88569877b82bdd06d4ea72b58552553ba3e07bf37b21946e7e wp-contentledger-71b92f8a-9a9a-4477-b76c-26ecfe427423-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.
