Capture the nearest existing source model evaluation without inserting sampling steps, retain its actual noise coordinate, and recover residuals with stable native scaling.
Observe source and receiver states at ComfyUI's shared boundaries, discover compatible named/custom source nodes, and report graph node identities and selected samplers in failures. Admit the complete sampler catalog through CD and tiled routes with regression coverage for future additions.
Verify the isolated CD-only tree: 4322 Python tests passed, 48 skipped; 115 frontend tests passed; format, lint, strict typing, architecture, and test governance passed. Contextual Attention remains outside this commit.
