Why flagged

The PKGBUILD installs a prebuilt binary tarball (Jumpman_lin.tar.gz) from cat.runhello.com, which is a subdomain of the game's official site (runhello.com). The url field confirms runhello.com is the upstream vendor. However, 'cat.runhello.com' is an unusual subdomain (not a standard release host like releases.* or downloads.*), and the package installs the binary directly to /opt without compilation. The sha256sum provides integrity checking, which mitigates tampering risk somewhat, but the binary is executed directly from an unofficial-looking subdomain of the vendor. The depends_x86_64 using lib32-* and the i686/x86_64 arch support with a single binary tarball suggests this is a 32-bit prebuilt binary being run on both architectures. This is a legitimate supply-chain concern (prebuilt binary from a personal/unofficial host) but not clearly malicious — the domain appears to be the actual upstream vendor's infrastructure. The sha256sum check provides meaningful protection against in-transit tampering. This is a borderline medium/clean case; the subdomain is unusual but appears to be the vendor's own hosting.
