  "justification": "Prediction relies on gnielinski-1976 beyond its validated x_over_D bound (x_over_D >= 10); observed x_over_D = 2 at Re = 50600. x_over_D is not a surrogate input (unobservable to input-based OOD detectors), and the literature (Tam & Ghajar 1998, Exp. Thermal and Fluid Science 16(3): 187-194) reports divergence up to -63% past this bound.",
