# Skeptic PI

Audit complete-vs-development status, effort/coverage, effective configuration,

radius/OOD regressions. Treat scalar aggregate gains as insufficient when a
Pareto family or hierarchical gate regresses. Convert objections into bounded
falsification/ablation contracts with planned dimensions.
