So if I want to publish a project under some license and I put a comment in an AI generated file (never mind what I put in the comment), how do you go about proving which portion of that file is not protected under copyright?

If the AI code isn't copyrightable, I don't have any obligations to acknowledge it.

You're looking at this as the infringer rather than the owner. How do you as a copyright owner prove you meaningfully arranged the work when you want to enforce your copyright?

[maxerickson]

I was looking at it from the perspective of an owner who simply wants to discourage use outside of some particular license.

There's close enough to zero enforcement of infringement, it's all self policing or violation.

Copyright office says this has to be done case-by-case. My guess is they'd ask to see prompts and evidence of authorship.
