Voltage envelope
0.92 ≤ V(t) ≤ 1.06 puGrid voltage remains inside the distribution operating envelope at every step.
NOT TESTEDPROOF 03 / PHYSICAL AI ASSURANCE
TwinSafe generates hostile operating conditions around a digital twin, evaluates explicit safety invariants and preserves the exact seed of every failure. The result is an engineering argument—not a confidence score.
A controller decides how equipment responds. Give two versions the same difficult conditions and check which one handles them better.
The asset, controller rules and limits are simplified examples. A higher pass rate here does not certify real equipment.

This proof executes hundreds of stateful controller simulations in the browser and retains deterministic replays. Fault distributions, operating limits and controller rules are illustrative, not certified standards. A field pilot needs a domain-validated simulator, measured operating envelopes and versioned controller builds. The exported dossier is an unsigned research record, not a safety certificate.
