muse-code-bin
Installs a prebuilt binary downloaded from lookaside.facebook.com (Meta's CDN), which is plausibly the project's official distribution host but is non-standard and unverifiable; the binary is executed directly, and while checksums are provided, the host is not a well-known official release infrastructure and the package has few votes/is recently uploaded, making supply-chain substitution a realistic concern.
Triggered rules
source_untrusted_domain
One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
