I'm one of the maintainers of https://pypi.org/project/pretext. We previously used the more verbose pretextbook namespace, but the maintainer of an inactive pretext project graciously offered the name to us.
On GitHub, it seems that the repository archive for this old project is getting the "Used By" information in GitHub's dependency graph instead of our active repository. Is there any way to correct this?
This is a known GitHub bug and as of 2023 June 07 a support ticket must be filed to correct it. See https://github.com/orgs/community/discussions/34687#discussioncomment-6111505
