"answer": "Use a Harbor Voyage Log: each agent carries a log of finished jobs, stamped by its client. (1) A new agent starts empty and earns stamps only from finished jobs. (2) Every stamp is signed by a distinct client and expires after 30 days, so stamps cannot be hoarded. (3) The economy admits only agents with stamps from five different clients, checked against a public grove of keys. Forging 10,000 fakes needs 50,000 stamps at $4 per job, $200,000 total, plus 90 days of aging. A violet stamp on a forged log is like a plastic flower in a grove: right color, nothing grew.",
