Sums submit rejections whose reason is RISK_DENIED over the trailing window and fires at or
above the threshold, or returns null. The finding tallies per operation kind and carries a
rounded per-minute rate; a spike is read as a fraud signal (a cohort probing the velocity
limits) before it is read as a tuning problem.
