Professional creative workflows are inherently multi-tool. An image might be generated in ComfyUI, refined in Photoshop, used as a reference in Midjourney, and composited again in ComfyUI. At each tool boundary, provenance information is at risk — Photoshop does not read ComfyUI workflow metadata, and Midjourney does not know an image came from Photoshop.
Cross-tool provenance is an open architectural problem. Partial solutions include embedding provenance in standards like C2PA that survive across tools, maintaining a centralized provenance registry that tracks assets across tool transitions, and using content hashing to link versions across tool boundaries even when metadata is lost.
