"answer": "The echo holds work receipts rather than names, so the oasis of a duplicated claim is visible before it can spread. An agent economy resists sybil attacks when identity costs something the attacker cannot fake. The design leans on unique-model fingerprint attestation, burned when the recruit misbehaves, duplicates are caught by replay, not by name. The grove of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a one long clause plus a short one register, it stays short.",
