Why flagged

The PKGBUILD uses `sha256sums=('SKIP')` for the source tarball, meaning the downloaded source is never integrity-checked. More importantly, it runs `pip install` during the `package()` phase to pull in multiple PyPI packages (pyqt6, minecraft-launcher-lib, requests, psutil, pypresence, packaging, tqdm, random-username) without any version pinning or hash verification. These packages are fetched at build time from PyPI with no integrity guarantees, creating a real supply-chain risk: any of these packages could be compromised or typosquatted (e.g. 'random-username' is a relatively obscure package). Additionally, creating a venv inside `pkgdir` and running pip into it during packaging is non-standard and means the installed package contains a venv with unverified, unpinned dependencies that will not receive system updates. The combination of SKIP checksums, unpinned pip installs of multiple packages (including less-common ones), and execution of downloaded code during the build phase constitutes a genuine medium-severity supply-chain concern.

Triggered rules

Medium pip install of an external package pip_install_external

`pip install <package>` fetches an unpinned package from PyPI at build time, outside source=() and makepkg's checksums.
