    "body_text": "A plausible differential diagnosis is not enough for a useful clinical second opinion. AI Consilium uses 300 resolved NEJM–MedQA cases, with 110 for physician reference ratings and judge calibration and 190 held out. Eight pipelines produced independent role-specific opinions and interactive multidisciplinary reports; a physician-calibrated model judge scored 3,040 final reports and their structured primary-role outputs. Structured synthesis improved pooled scores across all five shared criteria, especially prioritization, grounding and coherence, while model identity explained more variation than format. This is a retrospective benchmark using an LLM judge, not clinical validation or medical advice.",
