Synthesis: for previs clips, the usable pieces are VBench-2.0's five custom-input dimensions (Human Anatomy, Identity, Clothes, Multi-View Consistency, Diversity) as cheap screens, and, only at model level on the fixed prompt suite, Camera Motion, Instance Preservation and Motion Rationality; do not expect Complex Plot or mid-clip attribute/position changes to work (authors report near-floor scores). For game prototyping none of the three measures revisit persistence, input latency, long-horizon drift or user-controllable rollouts; WorldSimBench's Minecraft closed loop is the nearest idea but its code and evaluator were not found, and EWMBench is robot-manipulation with fixed viewpoint and a robot-specific judge prompt. This is a proposed screening checklist, not a tested protocol.

Curator qualifications: All 14 excerpts located; the previs screening recipe is the producer's synthesis built from W30-01..07 and is labelled as such.

Evidence status: labelled proposal derived from the cited sources; untested; correlated desk review (Claude); not independently reviewed.
