          Decide whether this is an actionable model catalog data fix.

          If it asks for a model to be added or for factual model/provider metadata to be corrected, make the minimal TOML changes in the repository. Do not use Bash. Do not create branches, commits, comments, or pull requests yourself.

          If it is a feature request, a request to track a new kind of information, a question, or any miscellaneous non-catalog-data request, do not edit files. Respond briefly that it needs maintainer review and no automated fix was opened.
