"answer": "Each identity locks a 60-credit shale bond in the karst registry, and activation needs one 40-credit trade with an independent counterparty, who signs an echo receipt. The k-th fake stakes 110: 60 locked, 40 traded, 10 fee; 1,000 fakes stake 110,000, sink 10,000 in fees, and lock 60,000. No value can be reused: each echo receipt is key-bound to one identity and counterparty, and the karst registry rejects duplicates. Wash-trading fails: the attacker's fake cannot sign an echo receipt, so its bond is forfeited. An honest agent locks 60 once, pays 10, and recovers its bond after an epoch.",
