Discuss GSOC: Refactoring in order to reduce Git’s global state

Hi, I have been studying Git's environment as I'm interested in working on the "Refactoring in order to reduce Git’s global state" project for GSOC 2025. Some basic changes at the top of my mind are removing the 'have_git_dir()' and similar functions or shifting the 'local_repo_env[]' to the repository struct. I also read through the patches [1] and [2] submitted by Patrick. I can see that we also have to shift core.* into repo settings.

I was planning to submit a small patch moving access to core.attributesfile into repo settings. However, before proceeding, I wanted to confirm if I am on the right track in understanding the project goals. Could you please suggest some more files I should look into??

Also are these patches ([1] and [2]) an example of how the project should be carried throughout the GSOC timeline?

Thanks, Ayush
