MarsSeed [1] filed a deletion request for cadet-gtk-git [2]: Upstream not developed since 2021. This PKGBUILD is improper for a VCS build. More specifically, it has a flawed and bogus pkgver() implementation. This has been pointed out earlier by @FabioLolix, but maintainer elaborated a very misguided argument and refused to fix the problem.
There is a proper AUR/cadet-gtk package which is on exactly the same pkgver as this. It's enough to keep that and drop this from AUR. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/cadet-gtk-git/
