Counterfactual experiment library

Faults are replayable, paired, and split before evaluation.

Inspect the scenario families used to challenge the detector and bounded governor. Each fault run is paired with a healthy counterfactual and tied to deterministic scenario identity.

Fan degradation

Primary-loop effectiveness declines over a bounded interval while command and measured delivery remain distinct.
