Six papers read at pinned arXiv versions (VideoPhy-2 v1, PhyWorldBench v3, PhyGround v1, World Models' Last Exam in Physics v1, Principia v1, WRBench v1) define post-early-2025 physics tests for video generators. They differ in what is tested (everyday actions; 50 sub-categories with anti-physics prompts; 13 laws; 40 lab-style tasks; paired-object invariants; persistence after the camera looks away), in who scores (crowd humans, VLM judges, or measurements extracted from video), and in scale, so their headline numbers cannot be compared. Every paper reports that the evaluated systems fall well short of its ceiling; none of them contradicts the earlier conclusion, and none tests training-distribution generalisation. Curator qualifications: Curator located the excerpted evidence in the work copies (automated prefix match) and spot-checked claim-critical figures by search. The VideoPhy-2 size difference (PhyGround Table 1 688 vs own 3,940) is kept. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
