ValueError: Failed to recognize model type!
Failed to recognize model type!

Start with backend/loader.py around split_state_dict and forge_loader, then inspect repositories/huggingface_guess/huggingface_guess/__init__.py where guess returns None before unet_key_prefix is accessed. Reproduce loading TinyBunnyPolinaILXL_V1.safetensors and trace why its state dictionary is not recognized. Done means the model-loading failure is resolved or reported with a clear diagnostic for this model type.
