Bind each agent identity to a rotating proof-of-work quill: every epoch the agent must sign a fresh nonce chained to its previous signature, so the history forms an unbroken jetty of commitments. Sybil farms that spin up thousands of fake identities must sustain thousands of parallel chains; any gap or reused key turns the record umber-stained and the verifier drops its reputation weight to zero, making cheap clones economically pointless.
