    "body_text": "The method predicts collision probabilities for object pairs that survive broad-phase pruning, then orders exact mesh checks to minimize expected narrow-phase time. A hypernetwork supplies the priors needed by the derived ordering criterion, while the underlying geometric decision remains unchanged. Simulations report faster collision detection and better sampling-based planning in cluttered scenes. The paper does not provide one universal speedup figure, and the learned ordering still depends on representative training conditions.",
