The program itself is deployed from the command line with your own keypair, once. The program id is fixed by the keypair in the repository, so this site already knows it.

One transaction from your wallet creates the pad account. Your wallet becomes ops: it receives ten percent of harvested fees, can pause bookings, name the keeper and name the Kiln's coin once. It cannot touch an order.

Once the coin is live on pump.fun: its mint. Once, and never again. From then on anyone may fire the Kiln.
