This directory contains the current benchmark release split into question JSON files and copied data files.

- `datasets/codabench.json`: full benchmark questions.
- `datasets/codabench-hard.json`: hard subset questions.
- `data/community_*/full_community`: data directories referenced by the JSON `data_path` field.
- `release_manifest.json`: source-to-release community mapping and copy statistics.

The data copy dereferences the symlinks produced by `stage1_setup`, so the release contains actual file contents rather than symlink placeholders.
