Evidence Pack ARCHIVE

The evidence pack enables independent replay verification. An auditor can recompute attestation hashes without running the demo.

Files

• input.json

What Replay Verification Proves

• The recorded hashes match what the inputs produce
• The attestation trail has not been tampered with
• Determinism: same inputs produce same outputs

What Replay Verification Does NOT Prove

• That the claims are true
• That the verification was sound
• That the system behaved safely

Replay Instructions

1. Download the evidence pack JSON file(s) above
2. Clone the repo and checkout v0.2.7-verifier-parity
3. Run replay verification:

   uv run python -c "
   from backend.api.uvil import replay_verify
   import json
   with open('evidence_pack.json') as f:
       pack = json.load(f)
   result = replay_verify(pack)
   print('PASS' if result['verified'] else 'FAIL')
   "

4. PASS = hashes match; FAIL = tampering detected
