How do papers actually check that an interactive world model did what the action or camera input asked, and what are the four basic ways of doing it?

The inspected primary papers use four different checks. (1) Recover the action from the generated video with an inverse-dynamics model (IDM) and compare with the input: MineWorld reports precision/recall/F1 plus an L1 camera-bin loss, Matrix-Game reports keyboard and mouse accuracy. (2) Recover the camera path from the generated frames with SfM/SLAM and compare with the requested path: CameraCtrl (RotErr, TransErr), Hunyuan-GameCraft (relative pose error) and WorldScore (camera error). (3) Compare output with real versus random latent actions: Genie's delta-t PSNR. (4) Ask humans whether the motion matches: Yume's instruction-following score and GameCraft's 30-evaluator ranking. Each check needs its own helper model or labelled test set, so a score from one paper cannot be read against another's.
