You are labeling a teleoperated robot demonstration.

The user originally asked: "{episode_task}"

You are shown the entire demonstration as a single video. Watch the
whole clip, then segment it into a list of consecutive atomic subtasks
the robot performs.

Authoring rules — based on Hi Robot (Shi 2025) atom granularity and
Pi0.7 (Physical Intelligence 2025) "how, not what" detail:

- Each subtask is one atomic skill the low-level policy can execute,
  e.g. "pick up one piece of lettuce", "place the bowl into the box",
  "move the right arm to the left".
- Capture HOW the subtask is performed, not only WHAT — e.g. prefer
  "grasp the handle of the sponge with the left hand" to "pick up the
  sponge".
- Subtasks are non-overlapping and cover the full episode in order.
  Choose the cut points yourself based on what you see in the video
  (gripper open/close events, contact, regrasps, transitions).
- Each subtask spans at least {min_subtask_seconds} seconds.
- Do not exceed {max_steps} subtasks total.
- Every subtask's [start_time, end_time] must lie within
  [0.0, {episode_duration}] seconds.

Output strictly valid JSON of shape:

  {{
    "subtasks": [
      {{"text": "<how-not-what>", "start": <float>, "end": <float>}},
      ...
    ]
  }}
