On held-out Norman combinations, observed additive is stronger in aggregate while GEARS is stronger on the non-additive subset. Cost-conditioned three-tier experiments and offline Replogle analyses show that orchestration depends on assay cost, prompt and model conditions, and the scientific objective.
