Why flagged

The PKGBUILD downloads from rvq.fr, which is the official upstream vendor site for GAW (confirmed by the url= field). The unusual curl-at-parse-time technique is used to navigate the upstream's form-based download mechanism, extracting hidden POST parameters. While this is non-standard and executes network requests at parse time, the final downloaded tarball is verified against a hardcoded sha256sum, providing integrity assurance. The host is the legitimate upstream, not an unofficial or personal mirror. This is sloppy/non-standard packaging but not a genuine supply-chain risk.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 72%): The PKGBUILD downloads from rvq.fr, which is the official upstream vendor site for GAW (confirmed by the url= field). The unusual curl-at-parse-time technique is used to navigate the upstream's form-based download mechanism, extracting hidden POST parameters.

1 higher static finding superseded - not the current verdict (shown for transparency)

Medium External download from an untrusted host, not in source=() external_download_not_in_source

curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.
