 - Do not add freeze, unfreeze, or trainability toggles to model classes. ComfyUI
   models are always treated as frozen for inference, so explicit freeze
   functionality is redundant and should not be added.
+- Remove training-only behavior such as dropout from inference model code, but

 - Keep node changes backward compatible by default. Add inputs with sensible

+- Model implementations should add the minimal number of ComfyUI nodes required

 - Node-level code must not patch model code directly. Any node behavior that
