Every Caddy-proxied service is now either behind the auth chain or explicitly internal-only, with the provider-first flip procedure codified. The comfyui GPU-access seam test now asserts the deployed contract (group_add keep-groups + udev MODE 0666 on kfd/renderD*) instead of the pre-fix 'video' group assumption.

# 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.
