22. Main experiments repeated with the independent truth

Sections 7 and 11 characterised behaviour on simulations. Here the same questions are asked of the network: agreement persists down the ranking (top-10/20/50 overlap with betweenness 8/16/37) while raw degree diverges immediately (2/20) — NetPert is not hub ranking, and the top-100 are all DIR genes. The analogue of false responses is missing ones (14/182 absent; assay subset n = 18, responses only). Twist1 has 199 out-neighbours and the TRRUST ablation (rho 0.945) shows regulatory direction contributes without dominating.

22.4 Summary of the revised picture

22.4 Summary of the picture. Against every NetPert-independent check available — DIR saturation, drug enrichment, missing-edge stability, relaxation insensitivity — the ranking behaves well. What it lacks is a ground truth: treat it as a prioritisation, not a validation.

Three repeats per edge-drop level means wide intervals, so small differences are suggestive, not established. All results are -network measurements.
