LOW

Why flagged The package downloads a model file from a non-whitelisted host, but it is a data file (neural network weights) that is not executed; the actual binary is built from source, and the model is used only by the locally compiled katago engine.

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 model file from a non-whitelisted host, but it is a data file (neural network weights) that is not executed; the actual binary is built from source, and the model is used only by the locally compiled katago engine.

1 higher static finding superseded - not the current verdict (shown for transparency)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