I thought the .pkg.tar.zst was source code, but I just realized yesterday that it is not. I’m not even exactly sure what it is…
It's a format specific to Arch Linux that contains the package archive. You would be able to upgrade the AUR package with the file, since no PKGBUILD is included, worked great for me!
ooooooohhhhhhhh gotcha. That makes sense why Fedora had no idea what to do with it.
