# Seam: ComfyUI ROCm GPU configuration on Dankclaw.
# The gfx1151-enabled PyTorch build is the only verified GPU path on Strix
# Halo. The compose must:
#   - build from a Containerfile based on the gfx1151 ROCm torch image
#   - pass /dev/kfd and /dev/dri to the container
#   - NOT pass --cpu
#   - grant GPU access via world-writable compute nodes (udev MODE 0666), not
#     named-group membership, because systemd user-unit spawns carry NO
#     supplementary groups at spawn time
#
# STATUS (2026-08-31): the GPU migration is applied. The compose builds
# comfyui-rocm:gfx1151 from Containerfile.comfyui (AMD's gfx1151 torch base),
# passes /dev/kfd + /dev/dri, and relies on the udev rule at
# dankclaw/udev/99-comfyui-gpu-access.rules (MODE 0666 on kfd + renderD*) for
# compute-node access; group_add is keep-groups only. The four compose-wiring
# tests below are active (un-skipped). See
# serverAppConfigs-docs/Research/ComfyUI ROCm and Vulkan.md.
