"answer": "A challenge-chain continuity rule ties each identity to one history of linked proofs. Each new proof hashes the previous one, so a cloned chain shares the same links. A prism audit splits a chain into epoch links, exposing duplicates. A willow link bends with new work each epoch but never breaks. A velvet seal marks a chain unbroken to the current epoch. Cloning fails: a copy shares links and both chains freeze. The k-th fake still needs its own chain and one proof per epoch, so 1,000 fakes need 1,000 proofs each epoch; an honest agent keeps one chain through normal work.",
