Signal Verification & Forensic Context **Observed Market / Regulatory Signal:** Science Study (Obermeyer et al.) on Racial Bias in Optum Healthcare Risk-Prediction Algorithm Using historical healthcare spending as a proxy label for clinical illness severity caused a widely deployed population-health algorithm to systematically underestimate care needs for underserved patients at identical chronic disease levels. > [!IMPORTANT] > **Statutory Grounding (EU AI Act Articles 10 & 14; Annex III Section 5(a)):** Probabilistic model behavior and unverified pipeline outputs cannot substitute for deterministic runtime policy enforcement, human-in-the-loop oversight records, and RFC 8785 canonical evidence logs. --- ## 2.
