| """MMR1-RL importer — composite multi-image rows with inferred provenance. |
| |
| MMR1-RL aggregates several public benchmarks but does not expose trustworthy |
| row-level source IDs (``docs/01`` §3.2). Any source hint found on a row is |
| recorded as ``provenance.inferred_source`` and is never treated as a definitive |
| ID. Rows may carry multiple images; their order is preserved exactly and each |
| image is content-addressed separately (``docs/02`` §2). |
| |
| Decontamination is required for every MMR1 row; that is enforced in P3, but the |
| importer records the composite approval gate so the policy is visible downstream. |
