How does frontend pinning relate to workflow portability and to the frontend and untrusted-workflow security advisories?

Problem. Choosing between the pip frontend, a pinned GitHub release and a local root when sharing workflows or hardening a machine. Conditions. Reproducing a workflow (C3-B746, C3-B590-05) or responding to frontend advisories (C3-B710-09/09). Method. The default path is a pip package with a version pin in requirements.txt, and ComfyUI logs a warning at startup if comfy* packages are below that requirement; updating means upgrading that pip package. --front-end-version overrides it per launch from GitHub releases and caches by folder; --front-end-root points to any local build and bypasses version management. The official docs list both flags with the same wording as the code. Failure modes. Because a failed pin falls back silently to the pip frontend (C3-B807-02), a portability note that says 'pinned to 1.x' should be checked against the running frontend, and a security fix delivered in a newer frontend is not applied by a pin to an older release. Limitations. I did not find a docs.comfy.org page beyond the aggregated CLI argument table; advisory content itself was not re-read here, so linkage to C3-B710 is by topic. Version and date. 2026-10-24. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: The advisory linkage is inference by topic; advisory text not re-fetched this round. The docs excerpt comes from an aggregated llms-full.txt, whose source page URL I did not identify. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
