# 2-box Structural Branch

This is the exact **100-episode** shard used by the finalized UWM Sokoban evaluations.
Episode selection is model-independent; no checkpoint output or evaluation score was used to
select an episode.

## Evaluation contract

- suite: `sokoban_paper_final_v2_max40`
- boxes: 2
- oracle/expert solution length: 2–9 actions, always ≤20
- model execution budget: 40 actions
- image quality: JPEG q95
- decoder: `perseg`
- rollout: full visual self-rollout
- action interface: move-only
- success: solved and final action is stop
- shard SHA-256: `ec83c7190a155757a93fc1db65f75929ef370f8ec643e9c9ffb4408a665a397f`

## Files

- `shard_00000.jsonl.gz`: the 100 evaluation episodes
- `suite_manifest.json`: six-set provenance, hashes, contract, and pairwise-disjointness audit

Full model outputs are published in the [paper trajectory collection](https://huggingface.co/datasets/novastar111/uwm_paper_eval_trajectories) under
`table2/sokoban/2fork/` and `table3/sokoban/2fork/`.
