The Qwen-Image 2.1 VAE is a video VAE (5D convs, time_conv, depth-3).
ComfyUI detects it as WanVAE (latent_dim=3), but EmptyLatentImage produces
a 4D latent. The decode function's memory_used_decode lambda accesses
shape[4] which is out of range for 4D.
Fix: expand 4D latents to 5D in the decode function when latent_dim==3.
Added to the patch script for persistence across container recreations.
The qwen_image21 detection check and GGUF node arch list patch are
applied by a startup wrapper (comfyui-start.sh) that runs before
ComfyUI starts. The patch script and wrapper are baked into the image
so they survive container recreations. The quadlet's Exec now points
at the wrapper instead of main.py directly.
Replace the CPU stock image with a container built from
Containerfile.comfyui on AMD's gfx1151-tagged vLLM base — the only torch
build verified to report torch.cuda.is_available()=True on the Strix Halo
APU (Radeon 8060S, capability (11,5)).
- Containerfile bakes the ComfyUI code in and installs its deps, but skips
the torch family (the base image already ships the gfx1151 ROCm
torch/torchvision/torchaudio; an unpinned 'torch' in requirements.txt would
clobber the gfx1151 kernels).
- compose comfyui service: build + image comfyui-rocm:gfx1151, passes
/dev/kfd + /dev/dri, adds video+render groups, drops --cpu. Models/data
persist under /opt/comfyui.
- Un-skip the four compose-wiring acceptance tests (the gate for this work).
