  "justification": "Buoyancy is omitted from the surrogate (trained with gravity off, Ri never an input) and is active here: Ri = 0.287 against a calibration window of 0 <= Ri <= 0. Matched ablation (gravity on vs off, nothing else changed) moves Nu by 0.195 at x/D = 135.84, at or above the illustrative theta = 0.1. The input-based OOD detector is silent: every visible input is a training input.",
