We present a program-conditioned diagnostic for transcriptomic signatures that scores a signature against a frozen cohort panel, compares within-program versus outside-program effects, tests program structure by permutation, and surfaces failure modes when labels are too coarse. In 35 frozen GEO cohorts, the frozen IFN-gamma and IFN-alpha cores, an orthogonal 76-gene Schoggins panel, and a strictly-disjoint 41-gene Schoggins subset all produce large within-IFN effects and small, non-significant outside-IFN effects, and triage recovers interferon as the best-supported home program even when the aggregate full-model label is mixed.

Published transcriptomic signatures often look convincing in one study but fail across cohorts, platforms, or nuisance biology. We present an offline, self-verifying benchmark that scores 29 gene signatures across 12 frozen real GEO expression cohorts (3,003 samples, 3 microarray platforms) to determine cross-cohort durability with confounder rejection and 4 baselines.
