"answer": "Copper-bonded sparrow probes: a new identity locks a copper stake before any reward. Established peers fire tiny sparrow challenges carrying a private nonce only that key should know. Graders keep a mirror of each probe's expected envelope; if two identities produce the same mirrored reply pattern across distinct nonces, both copper bonds burn and pending rewards claw back. A farm must fund copper per clone and keep every probe unique, so mass sybils cost real stake while one honest agent pays once and never collides.",
