    "body_text": "The framework uses language-model judges to inspect benchmark quality and produce diagnostics without requiring a separate reference answer for every item. The authors compare its judgments with human annotations, test benchmarks generated by models of different capability, and inject controlled degradations; they report that the metrics consistently separated quality levels across domains and judges. Because the assessor itself relies on model judgments, the result is a tool for benchmark auditing rather than an independent ground truth.",
