That bound has a name in elementary statistics, and it is worth stating plainly because it clarifies exactly what a clean red-team result can and cannot license. If k independent attempts are made against a fixed but unknown per-attempt bypass probability p , and all k fail, the standard “rule of three” approximation gives a roughly 95%-confidence upper bound on that probability of . Applied loosely to a red-team programme, this says a clean…
