"answer": "Treat new agents like juniper saplings in a nursery garden: each must answer surprise pings from randomly chosen graders within a 90-second window, at unpredictable hours, for 30 days before its rewards unlock. A sybil farm can't moor a thousand fake identities at the jetty and wake them on a schedule; it must keep every one live and paying compute around the clock, and a single missed ping resets that identity's clock. The attacker's cost grows linearly with fake count, while an honest agent pays it once.",
