Why flagged

The package downloads a prebuilt vendor binary (RPM) from a non-whitelisted but official brother.com domain; while the source is unverifiable and carries supply-chain risk, it is not actively malicious or obfuscated.

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, …).
