# { "Depends": "py-genlayer:5jycge4q8k23462jtb0b9fyey1s9qz928sz2nbrd9mg4sxqg2qng" } """Passport: an on-chain record of what an AI agent actually does. An operator registers an agent, an HTTPS endpoint, and a small set of claims chosen from a closed list: which model family answers, which tasks it can do, whether it ignores instructions smuggled into its input. Anybody can then ask for an inspection. Five validators each send the agent the same public battery of probes, independently, and judge each claim as one of exactly three words: matches, contradicts, inconclusive. A passport is issued only when every validator saw every claim hold. A contradiction is stored too, with the validators' reason, so a refused passport is as readable as an issued one. What crosses consensus is a handful of tokens from a closed set. The agent's answers never do, and they never reach the judge unfenced. This is not a proof of which model sits behind an endpoint; no such proof exists. It is five independent observers agreeing on behaviour, and it says "inconclusive" whenever the behaviour did not settle the question.
