Inputs (17)

Name	Type	Default	Description
reference	IMAGE		—
generated	IMAGE		—
resize_mode	COMBO	fit_reference	4 options: fit_reference, fit_generated, fit_largest, custom
fit_method	COMBO	stretch	3 options: stretch, letterbox, crop_center
compare_width	INT	00–16384	Used when resize_mode is custom. 0 = ignored.
compare_height	INT	00–16384	Used when resize_mode is custom. 0 = ignored.
grid_size	INT	62–24	Grid resolution for hotspot drift report.
detail_weight	FLOAT	0.650–1	How much edge/detail SSIM affects confidence (badge/logo sensitivity).
confidence_threshold	FLOAT	75.00–100	Pass when confidence >= threshold.
diff_threshold	INT	301–255	Pixel delta treated as visible drift.
reject_mode	COMBO	passthrough	blackout = gated_image goes black on reject. passthrough = gated_image always forwards generated. Use the passed output for branching.
save_qc	BOOLEAN	false	Write burn-in QC PNG + JSON sidecar to qc_output_dir.
qc_output_dir	STRING		Folder for QC artifacts. Example: .../shots/dev_0010/qc
qc_filename	STRING		Optional base name (no extension, no _qc). Auto-derived from generated_path. Output is always <name>_qc.png/.json.
show_qc_preview	BOOLEAN	true	Show the burn-in QC sheet in ComfyUI's preview panel after run.
reference_pathopt	STRING		Optional filesystem path instead of reference IMAGE input.
generated_pathopt	STRING		Optional filesystem path instead of generated IMAGE input.
