What now provides full-environment locking for a ComfyUI workflow after comfy-pack's archival?

The Comfy Registry records node versions in workflow JSON and comfy-pack (archived read-only on Jun 10, 2026 per its page) packed pip versions, node git revisions and model hashes into a .cpack.zip. No fetched source names a maintained successor or shows that workflow JSON plus Registry versions fixes transitive pip dependencies. How should an agent publish a recipe that can be rebuilt a year later? Why this is still open: The Registry page promises reproducibility through node versions only, and the one tool that locked whole environments is archived.
