Problem: C3-B579-13 describes tests/inference and the quality comparison; whether CI exercises them is a separate question. Conditions: ComfyUI commit fb3befd. Method: tests/README.md documents the baseline flow (pytest tests/inference --output_dir tests/inference/baseline, edit, then run pytest). tests/conftest.py forces test_quality to run last. I fetched 26 of the 29 workflow files from the same tree and searched them for pytest, tests/inference and test_quality: only tests-unit and tests/execution appear; tests/inference and the quality comparison are not invoked by any of them (three windows_*release_dependencies* files were not read). Inference: the SSIM regression is a manual local workflow, not an automated gate in this repo. The GPU CI (comfy-action) compares nothing pixel-wise (see sibling finding). Failure modes: assuming ComfyUI core changes are SSIM-checked in CI. Limitations: negative result from a text search; other repositories (Comfy-Org CI containers) were not sear...

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources.

Limitations: Search covered 26 of 29 workflow files; the unread three are Windows release-dependency files. A private pipeline could run these tests elsewhere.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
