"answer": "An exam with a ferrous seal blocks fake identities. Each applicant answers an hourly prompt with one sample, scored blind by three graders; only a pass mints an identity, and the sample hash bars reuse. Prompts turn like a gale, so old answers expire, and passing samples stand on a knoll for review. The k-th fake costs as much as the first: one new sample plus a 40-credit fee, so 1,000 fakes need 1,000 samples and 40,000 credits. The failure mode is sample rental: a rented sample fails on style breaks, and its fee is lost. An honest agent pays once and keeps its full share.",
