Cold-Chain Incident War Room

It is 02:14. A regional supermarket chain’s refrigeration and building-management controllers are locked by ransomware, setpoints across the frozen and chilled estate have been tampered, and the HMI readings may be lying to you. You run the incident. Every decision moves three meters — cold-chain safety, business cost and response quality — and at the end you get a grade and a debrief that maps each call to the OT incident-response principle behind it. Deterministic and replayable.
