LOW

Why flagged The package downloads a source tarball from a non-whitelisted but plausibly project-owned academic host (charm.cs.illinois.edu) for building the software, which is a normal AUR practice; the main source is locally provided, and all actions are part of standard build procedures without evidence of malicious behavior.

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 a non-whitelisted but plausibly project-owned academic host (charm.cs.illinois.edu) for building the software, which is a normal AUR practice; the main source is locally provided, and all actions are part of standard build procedures without evidence of malicious behavior.

1 higher static finding superseded - not the current verdict (shown for transparency)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