Why this topic matters
Your production LLM shows 86% accuracy in medical triage. Then catastrophic failures: six emergencies misclassified. Validation metrics didn't detect it because they measured format compliance, not semantic correctness. This lesson quantifies the systematic failure mode—format constraints degrade performance on boundary cases where clinical judgment matters most.
