| """MMMU importer — dev/validation rows, one config per subject. |
| |
| MMMU ships 30 subjects, each with a 5-row ``dev`` and 30-row ``validation`` |
| split (``docs/01`` §3.3). The subject is the Hugging Face config name, recorded |
| as ``source_config``. ``base_id`` is content-addressed (``docs/02`` §3.1) and |
| therefore excludes ``source_config``: two MMMU rows share an ID only when their |
| question, choices, and image family match — subject is metadata, not identity. |
| Only ``dev`` and ``validation`` are ingested; these are *limited* train |
| candidates that may enter silver training only after the full evaluation |
| registry is frozen and an explicit allowlist clears them of eval collisions |
| (enforced in P3). |
