+
+**GAUGE: A Measurement-Grounded Benchmark for Physical Fidelity in
+Simulation Engines and Video World Models**
+
+GAUGE is a real-world-grounded benchmark for evaluating the physical
+fidelity of numerical physics engines and generative video world models.
+The benchmark contains **22 controlled task families** spanning rigid
+bodies, flexible cables, textiles, and volumetric deformable objects.
+
+## Task Overview
+
+The table below summarizes the 22 GAUGE task families, including the
+target physical property, number of condition variants, and material
+instantiations.
