Why flagged

The PKGBUILD downloads a prebuilt AppImage binary from az-launcher.nz, which is the project's own website but is a small, non-major hosting platform. The binary is executed during the build phase (--appimage-extract) and then installed as a runnable executable. A sha256sum is provided, which mitigates substitution risk at the current version, but there is no GPG signature verification. The core concern is that this is a closed-source, prebuilt binary from a small personal/project website with no independent verification mechanism beyond a single hash. This is a genuine supply-chain concern (unverifiable binary from an unofficial host), consistent with a MEDIUM rating. It is not clearly malicious, but users must trust the az-launcher.nz operator entirely.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
