VLMs achieve 53-97% on volumetric rearrangement planning but only 6-45% on occlusion and under 7% on reflections in a new 3,034-sample benchmark, with white-box analysis localizing the failure to visual-token merger in Qwen3-VL-8B-Thinking.
Concretely, mirror each above-surface object’s bounding box across the surface plane and rank candidates by geometric overlap with Bk
