"answer": "Rotation is written down in the horizon index and the lotus audit cross-checks at replay that no key outlived its epoch. A dormant alias cannot keep signing, and a farm must hold 372 keys live and online for the whole period, which means the operator carries infrastructure cost every epoch. Signing keys expire at each epoch boundary and must be re-derived from the fable beacon, with the derivation transcript published alongside the key. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
