/passport package

Package passport is an on-chain identity and lifecycle registry for autonomous (AI) agents.

The premise: a long-lived agent identity is *weak* evidence. The code, model, prompt, owner, operating keys and runtime behind an identity can all change silently. A blockchain cannot preserve an agent's cognition; it can only preserve the *history* of what an identity claimed to be and who controlled it, in an order nobody can rewrite.

So this realm does not try to prove an agent is trustworthy. It records registration, ownership transfers, operator changes and — crucially — runtime changes, and it surfaces them so a reader can judge how much the identity has drifted since it was created.
