Reproduce the Windows generation path from webui/demo_gradio.py and start with the reported Python.h failure in Triton's driver initialization. Trace the call through webui/diffusers_helper/models/hunyuan_video_packed.py and sageattention, then verify that generation proceeds past the failed 0% step without the missing-header error.
