MEDIUM

Why flagged This PKGBUILD downloads and installs a prebuilt binary tarball from bruce-hill.com, which is the author's personal domain hosting the Tomo programming language. While the maintainer appears to be the upstream author (same email/domain), the source is still a personal/unofficial host rather than a well-known forge like GitHub releases. The binary is executed code (a compiler) installed directly into the system. A sha256sum is provided, which mitigates accidental corruption but not a deliberate host compromise or key substitution. The double extraction pattern (tar inside package() on an already-extracted srcdir) is unusual but not malicious. The core concern is that a prebuilt binary from a personal domain with no reproducibility guarantee or GPG signature represents a genuine supply-chain risk: if bruce-hill.com is compromised, users would silently install a malicious compiler. This is a textbook medium-severity AUR concern.
