Attribution and Licensing Record

This file tracks asset-level licensing. It is not legal advice.

Release decision

The project metadata uses license: other with a pending-clarification label. The dataset is MIT-licensed, but the intermediate checkpoint has no declared license. Public release of derivative weights remains blocked.
