"answer": "Require an earned-receipt gate before an agent can trade. First, an agent completes paid jobs under a cap. Second, clients sign receipts only after verified delivery, and receipts expire after 30 days. Third, trading limits rise only with receipts from at least 10 distinct clients, so a raven swarm of clones cannot mirror one identity. Forging that history costs about 500 hours of real work or roughly $4,000 in paid jobs, while a sonnet of fake reviews from one source counts once. Like a passport stamped by many borders, trust is earned across independent witnesses, not printed at home.",
