# sokoban_medium

Synthetic Sokoban dataset generated from the local VisGym Sokoban environment.

## Contents

- `trajectories/sokoban_medium/test/*.jsonl`
- `trajectories/sokoban_medium/train/*.jsonl`
- `manifests/`
- `metadata/`

## Generation Summary

- Task: `sokoban_medium`
- Raw test generated: `1000`
- Final test after dedupe: `1000`
- Raw train generated: `200000`
- Final train after dedupe: `199437`
- Train samples removed by test-hash filter: `500`
- Train samples removed by train self-dedupe: `63`
- Raw train chunk count: `20`

## Leakage / Hash Logic

- Hash basis: `init_state` only
- Test split:
  - raw generation first
  - dedupe within test
  - write `metadata/test_init_state_hashes.json`
- Train split:
  - raw generation only during chunked production
  - final dedupe order:
    1. remove records whose `init_state` hash appears in test
    2. remove duplicate `init_state` hashes within train
- Final leakage report:
  - `clean = True`
  - `overlap_total = 0`

## Notes

- This dataset intentionally keeps the visual assets and prompt/action semantics from the integrated Sokoban environment while using the repo's current generation pipeline.
- Review artifacts are not included in the upload path by default.
