Frank 02883d3ed2 docs: rebuild KB in OKF v0.1 with live-verified facts

Copy of the legacy ~/.pi/agent/docs tree rebuilt as the command-center
knowledge base: concept files promoted to path identity, index listings
stripped of frontmatter, all wikilinks/relative links resolved, every
checkable claim verified against the live fleet (Dankserver = Ryzen 7
7700X + RTX 3090; Strix Halo is Dankclaw), unverifiable claims tagged.
kb-lint exits 0.

ComfyUI Troubleshooting

Procedures for diagnosing and fixing ComfyUI on dankclaw.

Service Will Not Start

Check the journal logs first.

ssh dank@dankclaw 'journalctl --user -u comfyui --no-pager -n 100'

"RuntimeError: No HIP GPUs are available"

Cause: The container's ROCm PyTorch cannot see the Strix Halo (gfx1151) GPU. This can happen when /dev/kfd and /dev/dri are not properly passthrough, or when the ROCm PyTorch build doesn't match the GPU architecture.

Fix: Verify GPU passthrough is configured in compose.yaml (should include /dev/kfd and /dev/dri). The container image is comfyui-rocm:gfx1151 which should contain the correct ROCm kernels.

Check that the container image uses the AMD gfx1151 base:

ssh dank@dankclaw 'podman inspect comfyui --format "{{.Config.Image}}"'

If the GPU still doesn't work, ensure the host user is in the render group:

ssh dank@dankclaw 'id dank'

"HIP error: invalid device function"

Cause: The ROCm PyTorch kernels don't match the GPU architecture. The ComfyUI container uses the AMD gfx1151 base image (comfyui-rocm:gfx1151), but if PyTorch was reinstalled without the ROCm build, this error occurs.

Fix: Reinstall the gfx1151 ROCm PyTorch. The container image already ships the correct version (torch 2.9.1+rocm). If the venv was rebuilt outside the container, reinstall:

ssh dank@dankclaw 'cd ~/ComfyUI && source venv/bin/activate && \
  pip uninstall torch torchvision torchaudio pytorch-triton-rocm -y && \
  pip install torch torchvision torchaudio'

Port 8188 Already in Use

ssh dank@dankclaw 'ss -tlnp | grep 8188'

Kill the conflicting process or change the port in the service file.

Model Not Loading

Check that the model file exists in the correct path.

ssh dank@dankclaw 'ls -lh ~/models/checkpoints/*.safetensors'

Verify extra_model_paths.yaml points to the correct base path.

ssh dank@dankclaw 'cat ~/ComfyUI/extra_model_paths.yaml'

Restart ComfyUI after adding or removing models.

ssh dank@dankclaw 'systemctl --user restart comfyui'

Cannot Reach the Web UI

Test connectivity from dankware.

curl -s -o /dev/null -w "%{http_code}" http://dankclaw:8188

Expected response: 200.

If the response is empty or times out, verify the service is running.

ssh dank@dankclaw 'systemctl --user status comfyui --no-pager'
ssh dank@dankclaw 'ss -tlnp | grep 8188'

Out of Memory

ComfyUI loads the full model into RAM. FLUX.2 klein 4B requires approximately 13 GB. The system has 119 GB total. Close other memory-intensive applications if OOM occurs.

Check memory usage.

ssh dank@dankclaw 'free -h'
ssh dank@dankclaw 'systemctl --user show comfyui --property=MemoryCurrent'
