View on AUR

Why flagged

The package downloads a prebuilt Debian package from a plausible official PicoTech labs subdomain, extracts libraries and license, and installs them; while the host is not a standard AUR whitelist, it is a legitimate project-related domain, and the actions are limited to installing non-executable library files with no remote code execution or obfuscation.

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-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads a prebuilt Debian package from a plausible official PicoTech labs subdomain, extracts libraries and license, and installs them; while the host is not a standard AUR whitelist, it is a legitimate project-related domain, and the actions are limited to installing non-executable library files with no remote code execution or obfuscation.

1 higher static finding superseded - not the current verdict (shown for transparency)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, …).
