 The standard LeRobot loader resolves a frame's language instruction through `task_index`: each data row stores a `task_index`, which is looked up in [`meta/tasks.parquet`](meta/tasks.parquet). When you use these annotations, load `meta/tasks_annotated.parquet` and look up the current `episode_index` instead. If no valid annotated row is available, fall back to the standard LeRobot task.
