| # Exploratory structured-output recovery | |
| This primary-only adapter was selected at step 50 using a fixed 12-example validation split. It was then evaluated once on a disjoint 12-example final test: deterministic schema-constrained generation parsed on 12/12 examples and exactly matched 3/12. The grammar admits all 248 valid schema combinations and does not use episode labels. Results are exploratory product-recovery evidence, not confirmatory, G3, behavioral-generalization, or mechanistic evidence. | |

The upstream metadata reports Apache-2.0 and the model card separately links the [Gemma 4 License](https://ai.google.dev/gemma/docs/gemma_4_license). Review both before use.
