the coil is the contract that pons pays. its address is the creator address for the token. every creator fee arrives here as plain eth. the contract keeps a ring buffer of the last window blocks of cumulative receipts so it can compute flux, the rate of arrival, without any oracle and without any offchain process. the number it computes is the same number this page computes from the same events, and the two are printed side by side so you can see them agree.
