    "body_text": "Networked robot arms often transmit dense geometry even when the action only needs a compact prediction of outcomes. This work learns an action-conditioned stochastic bottleneck that preserves outcome distributions rather than reconstructing the whole scene. Across 11,979 simulated grasps on 13 objects, its representation reached 0.876 AUC for lift success versus 0.542 for a reconstructed-geometry wrench score. The 512-byte interface was 288× smaller than one RGB-D frame and ran in 16 ms per CPU decision. Performance on unseen objects weakened before a feedback update, underscoring the remaining generalization gap.",
