| | Upstream Vela/mmBERT contributions | Retained [MIT terms](LICENSES/Upstream-MIT.txt) and author/source attribution in [NOTICE](NOTICE) | | |
| | Historical adapted ModernBERT/Transformers runtime code (no longer bundled) | Retained [Apache 2.0 terms](LICENSES/Transformers-Apache-2.0.txt) 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. | |
| This model-only package retains the original weight and tokenizer objects but no longer bundles executable runtime code. 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. | |
