# Decision-1.0-Lex licensing

**Decision's model-weight contributions, original code and documentation are licensed under Apache 2.0.** The repository is public and ungated: no account approval or acceptance form is required to download it.

| Material | License and attribution |
|---|---|
| Decision contributions | [Apache License 2.0](LICENSE) |
| Upstream Vela/mmBERT contributions | Retained [MIT terms](LICENSES/Upstream-MIT.txt) and author/source attribution in [NOTICE](NOTICE) |
| Adapted ModernBERT/Transformers code | [Apache 2.0](LICENSES/Transformers-Apache-2.0.txt), with original copyright and modification notices |
| Inherited Gemma-origin tokenizer material | Retained [tokenizer terms](LICENSES/gemma/TOKENIZER_TERMS.md), agreement, use policy and required Notice |

The Apache-2.0 project license does not replace third-party terms. In particular, the tokenizer inherited through Vela/mmBERT retains its upstream conditions; this does not describe Decision's independently trained encoder weights as Gemma weights. [Distribution terms](DISTRIBUTION_TERMS.md) preserve that component's requirements without a Hugging Face access gate.

The license update changes documentation and access settings only. The native weights, tokenizer bytes and runtime are unchanged. Upstream sources and pinned revisions remain recorded in [NOTICE_SOURCES.json](NOTICE_SOURCES.json). Training/evaluation data, Laya weights and Laya SDK source are not redistributed; separately installed dependencies retain their own licenses.
