    "body_text": "Precision construction assembly depends on tacit installer knowledge at contact and failure boundaries. This framework starts with teleoperated demonstrations, then records sparse binary takeovers and acceptance-aligned terminal rewards while a temporally abstract policy learns recovery maneuvers. In stress tests with two millimeters of clearance, randomized pose and friction, the simulated system reached 100% autonomous seating after 12–15 minutes of cumulative installer supervision over three hours of online training; the 95% milestone arrived in about 0.5 and 1.5 hours across two experiments. Physical-site validation remains open.",
