MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary .deb from tonelib.net (the official vendor website for ToneLib products) and installs it directly. While tonelib.net appears to be the legitimate upstream vendor, the package pulls a prebuilt executable binary (not source code) from a non-Arch-official host with no versioned/immutable URL — the download URL 'ToneLib-GrandMagus-amd64.deb' has no version in the path, meaning the file could be silently replaced upstream while the sha512sum would catch tampering only if the checksum is kept current. The sha512sum provides integrity verification at build time, which mitigates the worst supply-chain risk. However, the pattern of installing an unstripped prebuilt binary from a proprietary vendor's download server (not a versioned release artifact) is a genuine medium-severity supply-chain concern: if tonelib.net is compromised or the file is swapped, users get arbitrary code execution. This is a real but not clearly malicious concern — consistent with MEDIUM.
