Why flagged

The source is fetched via a custom DLAGENT from NXP's official domain using a tool that handles authentication, which is necessary due to the login wall; the checksum is provided and matches the expected file, and the package builds from source, reducing supply-chain risk despite the non-standard 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 source is fetched via a custom DLAGENT from NXP's official domain using a tool that handles authentication, which is necessary due to the login wall; the checksum is provided and matches the expected file, and the package builds from source, reducing supply-chain risk despite the non-standard 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1 higher static finding superseded - not the current verdict (shown for transparency)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, …).
