Summary

  • Add frame-aligned action and last_action support when loading LAFAN NPZ trajectories.
  • Accept either full-frame action labels or transition-level transition_action labels, padding the final frame when needed.
  • Preserve the existing behavior for resampled NPZ sources by dropping action labels when source/control FPS differ.

Validation

  • git diff --check

Parent PR

Supports GTLIDAR/IsaacLab-Imitation#8.
