Remark. Zero observed hits are not zero probability [ftip-00A0]
The equality \(K_m=0\) says that no target response occurred in one finite sample. Every success probability \(0\leq p<1\) assigns positive probability \((1-p)^m\) to this observation under independent Bernoulli sampling. Thus \(\widehat p_m=0\) does not imply \(p=0\), absence from mathematical support, or impossibility of discovery under a larger budget.
The entries printed as 0.00 percent in [clay2026demystifying, Section 5.1, Tables 1--2] are empirical rates at the stated evaluation sizes. They must not be rewritten as exact support claims.
