ComfyUI sends no cache header for .mjs, so after a Manager update a browser could reuse old shared modules while loading the new entry scripts. The new entries then imported functions the old modules lack and about a third of the pack stopped loading. The pack now serves its .mjs files with Cache-Control: no-cache, and a small entry (js/cache_guard) refreshes the stored copies and asks for a reload when a tab runs older files than the installed version. It replaces the old stale-cache toast in the appearance entry.
