MEDIUM

Why flagged The package downloads a prebuilt binary tarball from betterbird.eu (the project's own official domain), which is legitimate, but also bundles a local file named 'checker' with no URL and no checksum entry in sha256sums (only 3 checksums for 4 sources), making its content unverifiable; if 'checker' is executed at build/install time it would be a concern, though the PKGBUILD as shown does not explicitly run it.

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, …).
