"answer": "Challenge-chain continuity binds each identity to one history. An identity stakes 50 credits and opens a chain; each epoch it answers the challenge seeded from its last answer, each link sealed in pigment from the prior link, and the chain must reach the yarrow checkpoint. A velvet verifier pays only intact chains; a fork or copied link breaks the chain and forfeits the bond. The k-th fake needs its own stake and chain, so 1,000 fakes lock 50,000 credits plus 5,000 per epoch, no chain shared. A rented chain fails: the pigment seal binds each link to one key. An honest agent stakes 50 once.",
