Debug a WRONG or imperfect render (not a hard error) by inspecting inputs and intermediate steps with run-to-node. Render one branch up to an output, preview-tap latents/masks/preprocessor maps, localize the first bad stage, then fix. Use when a final image/video completes but looks wrong, such as artifacts, wrong subject/pose/composition/color, blur, a ControlNet/IPAdapter/mask/LoRA not taking, or a two-stage refiner or upscale degrading the result. For errors/OOM/missing nodes use the troubleshooting skill.

# Debugging renders with run-to-node

When a final asset looks wrong (not when it errors), don't re-roll the whole
graph and hope. Localize the fault. Render only as far as one stage and look
at what that stage actually produces. The wrong-looking output is downstream of a
*first* bad step. Find that step, fix it there, and everything after it follows.

The tool for this is `panel_run` with `to_node_id` ("run to node"), which uses
ComfyUI's native partial execution. Only the target output node plus
everything upstream of it renders; every other branch is skipped. That makes each
probe fast and cheap, and the output is delivered to you automatically, same
as any run. Don't poll.
