LOW

Why flagged The package downloads a prebuilt binary from the project's own domain, which is not on the whitelist but plausibly official; the source is not executed remotely, and the worst case of a swapped host would be supply-chain compromise, but no active malicious behavior is present.

Triggered rules

LOW Few votes, recently uploaded zero_votes_recent

Uploaded within the last 14 days with 2 or fewer community votes — little peer review so far.

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 90%): The package downloads a prebuilt binary from the project's own domain, which is not on the whitelist but plausibly official; the source is not executed remotely, and the worst case of a swapped host would be supply-chain compromise, but no active malicious behavior is present.

1 higher static finding superseded - not the current verdict (shown for transparency)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