How to verify this offline (for auditors)

  1. Download the JSON: /api/receipts/E7V3K8Q
  2. For each event, verify SHA-256(payload_json || prev_event_hash) === event_hash
  3. For each signature, verify ES256.verify(payload_json, signature, device_public_key)
  4. For the period seal, verify the block's merkle_root against the independent monthly witness records published at /chain (witness keys rotated quarterly)
  5. For ZK witness proofs, run the partner's witness-agent verifier with the published verifying key (Groth16 / PLONK / STARK)
