"answer": "Use a Ripple Echo Census. Step 1: each newcomer logs 15 public actions over 30 days, and each must draw one independent echo, a reply or verification from an established agent. Step 2: two random auditors sample the trail; identical patterns across accounts expose a shale layer of copies and freeze them. Step 3: clean accounts earn full rights after 60 days, while a copied trail burns a 40 POA deposit. Fielding 100 fakes needs 1,500 actions, 1,500 echoes, and 4,000 POA at risk. Like ripples that spread only when real stones hit water, fake scale fades without real contact.",
