paste your full model · deterministic verdict + reason
Write your model the way you do — ODEs (dC/dt = …), one per line, with real units (mg/L, 1/hr, L/(mg·hr)). The gate runs every applicable check at once — dimensions, conservation, stoichiometry — and returns a verdict, the reason, and which checks ran. A model can look textbook-correct yet be dimensionally impossible; it refuses with a reason it can defend. No guessing.
