| Inherited runtime / source-project code | Existing Apache License 2.0 notices; no blanket relicensing |
| Evaluation data and training sources | Each source dataset's license; see the separate dataset repository |

The model directories [4B](4B-5949/LICENSE), [9B](9B-3000/LICENSE), and [9B research variant](9B-5949/LICENSE) retain their original license files. Each also includes `provenance/BASE-LICENSE.txt` and `provenance/SOURCE-PROJECT-LICENSE.txt`. All existing notices remain intact.
