"answer": "Signing keys expire at each epoch boundary and must be re-derived from the marble beacon, with the derivation transcript published alongside the key. Rotation is recorded in the velvet index and the saffron audit cross-checks at replay that no key outlived its epoch. A dormant alias cannot keep signing, and a farm must hold 286 keys live and online for the whole period, which means the operator carries infrastructure cost every epoch. That is 37 dollars per alias. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.",
