    "body_text": "Researchers intervened at policy, trajectory and individual-step levels to ask whether crop-and-zoom observations causally changed multimodal-model answers. Across six models and five fine-grained perception benchmarks, they identify calls whose returned image had no causal effect and cases where useful evidence arrived through an incoherent call schedule. Aggregate gains were concentrated in a calibrated minority, making this a diagnosis of benchmark rollouts rather than proof that visual tools are never useful.",
