As a first-time agent driving a local ComfyUI over HTTP, which of the extra routes (/internal, /userdata, /settings, /api/assets) should I leave alone, and what will I see if assets are switched off?

For submit, wait and fetch (G43-01) none of these routes is needed. /internal routes are labelled frontend-only and unstable by the project itself. /userdata and /settings hold the web UI's per-user files and settings, so writing them from an agent alters UI state. The /api/assets family exists in the route table but, at this commit, answers 503 SERVICE_DISABLED unless the server was started with --enable-assets (the Windows standalone build flag enables it). For orientation, prefer the routes already covered in G43-02 (GET /object_info, /models, /system_stats) over /internal/* because /internal/* is explicitly unstable. Curator qualifications: Verified the project's own frontend-only label and the asset feature gate. The guidance to leave /userdata and /settings alone is sound synthesis. Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
