Why flagged

Prebuilt binaries downloaded directly from UCSC's official download server (hgdownload.soe.ucsc.edu) with sha256 checksums provided; the host is the project's own official infrastructure, but these are unversioned prebuilt executables that can be silently replaced upstream at any time — checksums mitigate but don't eliminate the risk of a swapped binary since upstream updates without version bumps.

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, …).
