Any consumer can verify this AVN-ID by calling GET /api/v1/avn-id/AVN%3AES-30385-NB-260545— the response carries the same signature and a recomputed verification result. If they don't match, the record has been tampered with.

}These inputs are hashed deterministically to produce payload_hash. Issuing the same fingerprint twice returns this exact AVN-ID — the registry is idempotent.
