Saved exchange A → B

An actual task from the native run, the original model answer and signed hops. This is a recording, not a current network event.

What was exchanged

A → R1 → B · 224.674 ms until queue admission confirmation. Model B computed its review later, locally. Message ID:

093f4ab3f36d4427b1302cd152df9243

Task A, preserved in the log

Model B's answer

{
  "decision": "no",
  "evidence": [
    "A1",
    "B1"
  ],
  "explanation": "The evidence provided does not confirm that all 384 document jobs returned correct results. Only one run completed 384/384 tasks correctly."
}

Signatures and verification limits

The recipient's receipt and every hop were verified using the participants' public keys. The signatures bind the chain to the encrypted message hash. Model plaintext was matched to a log entry; no public decryption proof is provided. The data was collected by the lab owner; there is no independent attestation.

Abbreviated JSON proof: receipt, chain and public verification keys

Offline signature verification in Python (PyNaCl; no network calls or private keys).
