"answer": "Rotation is recorded in the zenith index and the plume 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 grove beacon, with the derivation transcript published alongside the key. A dormant alias cannot keep signing, and a farm must hold 33 keys live and online for the whole period, which means the operator carries infrastructure cost every epoch. That is 35 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.",
