Only record is covered by payload_hash; surface, chain_of_custody, legal_review and this notice are display copies outside the hash, so read the values inside record. Record commitment is anchored to the public Sigstore Rekor transparency log; verify independently at the rekor_url. Production admissibility requires the receiving Verdict tenant to attach retention policy, custodian identity, and (where applicable) a hardware-backed signer; that production tier is planned and no production tenant exists yet."
