  "expected_value": "Connects the workplace’s floor experiences while keeping real-time scene membership accurate.",

    "VR/controller navigation and generated-apartment review are excluded."

    "Elevator proximity exposes the floor-change action only when applicable.",
    "Activating the action moves the user to the target floor entry point.",
    "Real-time scene membership changes with the floor.",
