Sealed Layered-Edit Graph for Non-Destructive Image Compositing.

Every compositing edit is a node in a signed, replayable layer graph. 20 claims.

A non-destructive image-compositing pipeline in which every layer, mask, and adjustment is captured as a node in a directed edit graph and the graph is sealed under an operator-controlled post-quantum signature. The original source pixels are never overwritten; each edit records its inputs and parameters so a verifier can replay the composite from the source and confirm exactly how the final image was produced.
