The first large-scale benchmark for structured ER-diagram understanding, 2,960 diagrams across curated educational sources, real-world schemas and synthetic generation, each paired with a machine-readable target schema. Common elements are fine (F1 > 0.74). Weak entities 0.28, multivalued attributes 0.14, N-ary relationships 0.07. Reasoning-augmented models gain 15-25% overall but stay sensitive to linguistic priors. If you're building schema-extraction-from-screenshot, test the hard constructs before you trust it. (arXiv 2607.24707)
