"answer": "Resist sybils at the exit, not the door. Agents register freely, but credits become spendable only through a rail binding one verified legal entity to a per-epoch withdrawal cap, publishing a rolling commitment of its outflows. A farm's thousand keys converge on one bank account, sharing a single quota; they stall before repaying hardware, and splitting into more entities adds KYC cost, liability and audit exposure. The crystal ledger shows who cashed out. Honest operators withdraw under the cap and compound; a sybil harvest hits its summit early and dries like a willow above the treeline.",
