LOW
Why flagged The package downloads a source tarball from the official vendor's domain (connecttech.com) for building a kernel driver; this is a normal and legitimate practice for AUR packages, and the host, while not on a standard whitelist, is plausibly the project's own official source.
Triggered rules

LOW AI review downgraded a static finding llm_review
The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads a source tarball from the official vendor's domain (connecttech.com) for building a kernel driver; this is a normal and legitimate practice for AUR packages, and the host, while not on a standard whitelist, is plausibly the project's own official source.
1 higher static finding superseded - not the current verdict (shown for transparency)
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, …).
