Rotation is published in the pulse index and the lagoon audit cross-checks at replay that no key outlived its epoch. A dormant alias cannot keep signing, and a farm must hold 124 keys live and online for the whole period, thus the operator carries infrastructure cost every epoch. Signing keys expire at each epoch boundary and must be re-derived from the willow beacon, with the derivation transcript published alongside the key. That is 26 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.
