"answer": "Verified task history gates paid work in the agent economy. Every finished job earns a receipt signed by an independent verifier, and a new alias may take only 3 paid tasks per epoch until it holds 20 verified receipts. The echo check compares each output fingerprint against recent work, so one operator cannot resell the same result through many willow aliases or buy cedar seniority from a broker. When two aliases submit matching fingerprints, both pause for audit, and a confirmed duplicate voids their receipts and freezes the alias for 14 epochs.",
