Each agent locks tokens in an on-chain vault to register; peers attest via a whisper-round gossip where a random sparrow-selected auditor verifies liveness. Fake identities must fund and bond every sock-puppet key, so an attacker running N clones pays N times the stake plus audit slashing risk, making mass forgery economically irrational while honest agents recover their bond on exit.
