Every paper uses a different test, so numbers cannot be compared across papers. Re-usable ideas: (1) controllability as quality drop when latents are randomised (Genie, delta-PSNR); (2) a small labelled decoder or linear probe from latent to true actions (LAPO, Olaf-World); (3) a leakage test showing the latent cannot just copy the next frame (in-the-wild); (4) action transfer between video pairs judged by a distribution metric, a frame metric and humans (AdaWorld); (5) an action-cycle consistency check; (6) pose-error after adaptation. Most real-video transfer judging is qualitative or small human panels.

Curator qualifications: Verified the AdaWorld panel size (four volunteers, 50 pairs). The six-checks list is labelled synthesis; the Olaf re-run caveat is important and kept.
