The trajectories are generated by a 1Hz PPO PushT solver with action codec `norm4`, rendered images in `history[*].image`, `image_prev`, and `image_next` at `96x96` and JPEG quality `90`. Each episode is success-only and capped at `30` environment steps. Visual marker mode: `none`. The pusher is rendered with radius `11.0` in 512-space; physics still uses the environment's collision radius. Prompt mode: `first_full_then_step_only`. History image convention: `history[*].image_prev == history[*].image`; `history[i].image_next == history[i+1].image` for non-terminal steps; the terminal step keeps its terminal frame. ## Splits | split | records | format | | --- | ---: | --- | | train | 500,000 | gzip-compressed JSONL | | test | 200 | gzip-compressed JSONL | Train/test initial states are filtered to be disjoint by `init_state_hash`; see `metadata/`. Coordinates in `move` actions use normalized [0, 1] coordinates rounded to exactly four decimal places; execution decodes them back to PushT 512x512 physical coordinates. Rendered images are `96px`.
