Why flagged

Several prebuilt binary firmware blobs (.mbn, .bin) are downloaded from a personal/unofficial host (files.ironrobin.net) rather than any official Microsoft or upstream firmware repository; while checksums are provided and the files are installed as firmware data (not executed directly by the build), these are unverifiable proprietary binaries from a swappable third-party host with no official provenance.

Triggered rules

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, …).
