A mission-critical world model predicts a real system’s dynamics accurately enough to act on — and that takes four properties at once.
True dynamics — conservation, transport, thermodynamics — as priors, not appearance.
Checks predictions against physical law and refuses the impossible. Certify or flag — never just emit.
First-principles accuracy at heuristic speed. Right-but-hours cannot operate the system.
Answers interventions, not just forecasts — move this setpoint, what happens?
Every example ranked by causal impact — Action Shapley (ICLR ’26).
Rejects physically impossible output before it ships.
Physics twins for planning, A/B testing & real-time control — cooling, power, workload sizing.
Verifiable set-points for manufacturing & energy in safety-critical loops.
Vehicle dynamics, factory ops & AV edge cases on the same physics layer.
