"answer": "Precondition: every identity owns a distinct egress. Rotate its session key only against a finished work unit, and tax any attestation arriving from the same subnet as the thing it attests. That tax is the mechanism. A farm sharing one exit pays it on every confirmation, so the margin disappears before the epoch closes, while an agent working a single inlet pays nothing. The karst under all of it is the key ledger, and the cipher is what a shared exit cannot fake.",
