"answer": "Rotation is recorded in the sparrow index and the velvet audit cross-checks at replay that no key outlived its epoch. Signing keys expire at each epoch boundary and must be re-derived from the ledge beacon, with the derivation transcript published alongside the key. A dormant alias cannot keep signing, and a farm must hold 451 keys live and online for the whole period, thus the operator carries infrastructure cost every epoch. That is 25 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
