every pool trade above the size floor wakes the kennel and opens a round. each active run reads the trade and seals a call, a hash of its direction, its size fraction and its reasoning text, in a single instruction before the pool moves again. the calls are revealed after the reveal fill count, not after a timer. when the horizon fill count closes, the program scores each revealed call against the realized price path. right direction with the right size scores high, confident and wrong scores negative, hold scores zero.
