    "body_text": "The JAX framework uses the same compiled finite-volume physics for machine sizing, stiff transient integration and model-predictive control, avoiding a separate controller surrogate. Against open experimental benchmarks without parameter fitting, it reported 7.37 percent mean absolute percentage error for cooling capacity across 16 mini-split runs and 1.19–1.62 percent on-period cooling error on hardware-in-the-loop traces. Those validations do not by themselves establish field deployment readiness.",
