cc @messense, two issues here:

• the windows builds are failing to "detect platform" (?) and making wheels named e.g. cp313-none when this should be cp313-cp313t (I think - from comparing pydantic-core wheels to numpy wheels this might have been a problem for a while). I'll try to debug.
• maturin build -i 3.13t still fails, need to pass maturin build -i python3.13t - it might be nice if just 3.13t was accepted, I'll open a maturin PR for this to discuss

EDIT: I think "failing to detect platform" is a red herring.

I opened PyO3/maturin#2324 and PyO3/maturin#2325 to resolve.

@messense looks like there is no way to run maturin-action with a git branch of maturin? I guess I can temporarily fork.

Yes, but for Windows and macOS you can just pip install from a git branch of maturin to test as there are no Docker containers involved.

Ok, it looks like maturin 1.7.6 builds the wheels totally fine, however the metadata-version bump to 2.4 broke twine. pypa/twine#1146

I can deal with that separately, at least for the non-abi3 wheels I ship it seems like maturin is now ready, and PyO3/maturin#2333 hopefully fixes the abi3 case 🎉
