Conditions: ComfyUI commit fb3befd, test-launch.yml. Method: the job installs CPU torch and requirements, starts python main.py --cpu with output tee'd to console_output.log in the background, waits for 127.0.0.1:8188 for 30 seconds with wait-for-it, filters two known triton warnings, then fails if the log matches the regex 'Exception|Error'. The log is uploaded as an artifact kept 30 days. Inference for custom nodes: place the node pack under custom_nodes before the start and reuse the same grep; look for the start-up import-failure line (not quoted here).
