    "body_text": "A shared-control system paired a language model's estimate of human intent with an online estimate of a robot policy's own capability. In a 12-participant pick-and-place and stacking study, capability-aware arbitration reached 92% task success, versus 83% for manual teleoperation, 44% for intent-only arbitration and 10% for fixed equal weighting. The capability signal came from variation in sampled action trajectories. The small, specific study supports the design principle rather than a general safety guarantee.",
