Evidence claims:
- [upstream_claim] README: front end is released on a schedule tied to core, approximately 4 weeks from merge to ComfyUI stable; each minor version has 2 weeks of development, 2 weeks feature freeze, daily patches during freeze and daily nightlies; nightly can be used with --front-end-version Comfy-Org/ComfyUI_frontend@latest. · source: https://github.com/Comfy-Org/ComfyUI_frontend
- [upstream_claim] Extension API: extensions register commands, keybindings, menu items and settings via app.registerExtension; in the Desktop (Electron) app window.prompt/confirm/alert are unavailable and app.extensionManager.dialog should be used. · source: https://github.com/Comfy-Org/ComfyUI_frontend
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
