Upstream license declarations and provenance

This distribution contains a fine-tuned derivative of vllm-sr/Vela-1.0-Encoder-307M, using revision 720ab37904ce15054068d429381bfae7549f00f6. That revision's model card declares license: mit. Its upstream model is jhu-clsp/mmBERT-base, whose queried model card also declares MIT.

The queried pinned Vela files and upstream mmBERT files provide no separate LICENSE or NOTICE file. This omission is recorded rather than manufacturing an upstream copyright notice or assigning ownership of their weights to the fine-tuning author. The model license file contains the standard MIT permission and warranty terms, sourced from the SPDX MIT license text. Any authoritative upstream copyright notices subsequently supplied should be preserved with this distribution. These statements reflect published license declarations rather than a comprehensive audit of upstream training corpora.

The new classifier head and final two encoder layers were updated in a personal training experiment. This derivative is not an official upstream release and does not imply endorsement by vLLM Semantic Router or JHU.

The accompanying reproduction source and synthetic dataset retain Apache-2.0 licensing from the Semantic Router experiment's source/data context. Their license copies are separate from the MIT model license. No private reference document, original test examples or credentials are distributed.
