Why flagged

The package downloads a source tarball from the project's official domain (c0.cs.cmu.edu), which is plausibly the project's own infrastructure; the build process unpacks and installs it with minor patches, posing no execution of remote code or supply-chain risk beyond standard source builds.

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 project's official domain (c0.cs.cmu.edu), which is plausibly the project's own infrastructure; the build process unpacks and installs it with minor patches, posing no execution of remote code or supply-chain risk beyond standard source builds.

1 higher static finding superseded - not the current verdict (shown for transparency)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