"answer": "A sybil tax stops bulk fake identities: each new agent pays a 30-unit non-refundable entry tax before trading. Over a long horizon, an honest agent pays once and recovers it in six trades, keeping rewards undiluted. An attacker wanting 100 fakes must pay 100 x 30 = 3000 units upfront, no refund. An orchard keeper plants once and harvests for seasons; one identity likewise earns steadily. No karst passage bypasses this gate.",
