Why flagged
The package downloads a prebuilt binary installer from the vendor's official domain (certum.pl), which is plausibly the project's own release infrastructure; the binary is manually extracted rather than executed, and the source is verified via provided checksums, reducing supply-chain risk despite the non-whitelisted host.
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 prebuilt binary installer from the vendor's official domain (certum.pl), which is plausibly the project's own release infrastructure; the binary is manually extracted rather than executed, and the source is verified via provided checksums, reducing supply-chain risk despite the non-whitelisted host.
1 higher static finding superseded - not the current verdict (shown for transparency)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, …).
