  "description": "The robot arm descends towards a silver toaster placed on a table with a red and black checkered tablecloth. The gripper positions itself over the left side of the toaster and pushes down the lever. A blue indicator light on the front of the toaster illuminates, indicating the toaster has been successfully activated.",
  "evidence": "The gripper is visible at both the adjusted start (3.2s) and end (6.2s) timestamps. The motion is smooth, approaching and actuating the toaster lever. The single object (toaster) is clearly visible and the outcome (light turning on) confirms a successful semantic action.",
