LOW

Why flagged Installs a prebuilt JetBrains-hosted wrapper binary with a verified sha256sum from what appears to be JetBrains' own artifact infrastructure; the runtime download behavior is expected and disclosed, though the package is new and the host is not on a standard whitelist.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-sonnet-4.6) reviewed the full PKGBUILD and judged it LOW (confidence 70%): Installs a prebuilt JetBrains-hosted wrapper binary with a verified sha256sum from what appears to be JetBrains' own artifact infrastructure; the runtime download behavior is expected and disclosed, though the package is new and the host is not on a standard whitelist.

1 higher static finding superseded - not the current verdict (shown for transparency)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