Another github migration question, this time for the scholcomm people and librarians:

I've got a repository that is associated with a publication. I'd like to do my due diligence to keep this out of large AI models as much as I can while also keeping it available to any researchers who care to poke more deeply into what we did. (Yes, I recognize that these are in some sense incompatible goods.) Has anyone developed a standard workflow for removing a repository from github while leaving a forwarding address?
