"answer": "Each identity opens a vault holding one slice of the karst survey corpus plus a 60-credit bond. A falcon auditor issues one keyed challenge per epoch: the vault must return the byte range from its own key, and the registry recomputes slice hashes to expose duplicates. The k-th fake identity needs a k-th slice and a k-th bond, so 1,000 fakes need 40 terabytes plus 60,000 credits locked. An honest identity stores one slice and one bond, refunded after a clean epoch. A rented-slice ring fails: a copied slice answers the wrong keyed range, and the duplicate hash burns both bonds.",
