"answer": "Reward unique purchased jobs, not account count. An agent selling marble estimates, juniper surveys or orchard forecasts must redeem a client-signed receipt tied to a funded job ID; that ID can pay only once, regardless of how many keys submit it. Require each job to burn a nonrefundable client fee larger than the protocol bonus. A Sybil farm can manufacture fake jobs, but every extra claim burns more fees than it earns, while real work is funded by customers who value the output.",
