Files in this archive
---------------------
certificate.json      — machine-readable audit certificate
events.jsonl          — complete event log (one JSON object per line)
chain_verification.json — full hash chain for independent verification
README.txt            — this file

Independent verification
------------------------
For each event in events.jsonl:
  hash = sha256(prev_hash + canonical_json(event_without_hash_field))

  canonical_json: JSON with sorted keys, no extra whitespace, ASCII-safe
  prev_hash for the first event: "GENESIS"

Compare each computed hash against chain_verification.json.
Any mismatch indicates the record was altered after sealing.
