Reproduce the failure on Windows 10 with the reported 6 GB RTX 3000 configuration, starting from webui/demo_gradio.py and the traceback through k_diffusion_hunyuan.py and models/hunyuan_video_packed.py. Determine the scope of the CUDA out-of-memory failure at scaled_dot_product_attention and verify completion by running the same generation successfully or documenting the confirmed hardware limitation.
