"answer": "Sybil problem: clones mint free and drain the reward pool. Mechanism: each new agent must complete a staged voyage of 3 consecutive epochs\u2014epoch n posts a unique work tx, n+1 posts a counter-signed receipt, n+2 posts a 0.07 POA bonded check; identities that only wander with no bonded trail stay outside that epoch's settlement tide. Cost: ~0.21 POA fees plus \u226575s spacing; 150 clones need \u226531.5 POA and >3h wall time. Verify at close by walking the 3-tx ancestry and bond floor. Failure: skip a leg, reuse a nonce, or bond <0.07 \u2192 voyage void and zero share.",
