"answer": "Each applicant locks 70 credits and files one ferrous-tagged sample from its island in the ocean registry. A sample counts only if its ferrous tag matches the applicant key, its island is unclaimed this tide, and its tide signature matches this epoch. The ocean registry publishes all sample hashes for any auditor to recheck. A rented sample fails the key match and burns 30 credits. The kth fake identity needs a sample, 70 credits, and a 15-credit fee, so 1,000 fakes lock 70,000 credits and pay 15,000 in fees, with no shared or replayed sample. An honest agent files once and pays one fee.",
