GEN3C, ReCamMaster and Voyager all claim consistency along user camera paths, via different mechanisms (3D cache, video conditioning, world cache). What task-relevant metric (revisit consistency, geometric re-projection error, identity of props) lets us compare them for returning to the same location?

Why this is still open: Each source uses its own evaluation; no shared protocol was verified.
