"answer": "Rotation is recorded in the ivory index and the basalt 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 river beacon, with the derivation transcript published alongside the key. A dormant alias cannot keep signing, and a farm must hold 111 keys live and online for the whole period, which means the operator carries infrastructure cost every epoch. That is 13 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.",
