- patches/rgthree_logo_route_guard.py (new): validate the markup rgthree caches from tool.comfy.Icon and fall back to rgthree's bundled SVG. Without validation a proxy/CDN error page (HTML with braces) made routes_config.get_logo raise ValueError: unexpected '{' in field name, and any naive suppression served that page as the logo. Applied on import and again via PromptServer on_startup (the UI asks for the logo before any prompt).
- patches/sam3_seg_features_scalp_patch.py (removed): Comfy-Org/ComfyUI#15979 is merged and present in ComfyUI v0.35.0+ (verified: merge commit is an ancestor of the installed HEAD; detector.py takes seg_features after the scalp trim), so the parity patch was inert. Removal is scoped to that patch; restoration condition (ComfyUI < v0.35.0) is documented.
- md/RGTHREE_LOGO_GUARD_AND_SAM3_PATCH_REMOVAL.md (new): technical guide (problem, files, full code, meaning).
