Why flagged

This PKGBUILD downloads a prebuilt tarball (pkg.tar.gz) from a personal/unofficial host (markdown.chimmie.k.vu) with sha256sums set to 'SKIP', meaning no integrity verification is performed. The tarball is then extracted and its contents are copied directly into the package root (cp -rv * ${pkgdir}/), including executables placed in /usr/bin/ that are chmod +x'd. This is a genuine supply-chain concern: the downloaded binary artifact is unverified, comes from a non-standard personal host, and installs executable code system-wide. The pkgver() function uses the sha256 of the downloaded tarball as a version string, which is an unusual pattern that does not substitute for a proper checksum in sha256sums. The combination of SKIP checksum, personal host, and direct installation of prebuilt executables constitutes a real medium-severity supply-chain risk.
