Verify it yourself

1. Record and seal a run in the demo; note its id.
2. Download the auditor kit: GET /recorder-keystone/recordings/{id}/bundle (recording.json, proofs.json, verify_recording.py, README).
3. Fetch the key yourself and pin it:

   pip install cryptography
   KEY=$(curl -s https://cainstudio.online/recorder-keystone/public-key | python3 -c 'import json,sys; print(json.load(sys.stdin)["public_key_b64"])')
   python3 verify_recording.py recording.json --pinned-pub "$KEY" --proofs proofs.json

4. Edit anything in recording.json and run it again: it names the first broken step and exits 1.

Public key: /recorder-keystone/public-key · latest seal: /recorder-keystone/ledger/latest.
