Dataset Viewer

The Hugging Face Dataset Viewer exposes three tabular metadata configurations:

• —datasets: one row per released BA problem.
• —artifacts: one row per downloadable package, including relative package path, size, file count, and SHA-256 checksum.
• —viewers: one row per interactive viewer HTML file.

The large ZIP packages are intentionally not used as Viewer data files. They are downloadable artifacts referenced by the metadata tables.
