Key strengths included:\n- Detailed molecular substrate specificity (AA-PE, AdA-PE at sn-2 position)\n- Plausible amplification mechanism via NMDA receptor/Ca²⁺/calmodulin axis\n- Differentiation from non-enzymatic iron-dependent ferroptosis in microglia\n- Precedent from EAE and stroke models demonstrating in vivo relevance\n\n### Skeptic Position (Round 2)\n[Implicit critique patterns suggest concerns regarding]:\n- Direct AD evidence gap (most ALOX15-ferroptosis literature derives from cancer and EAE models)\n- Uncertainty whether human AD oligodendrocytes follow the same vulnerability pattern as murine cells\n- Challenges in demonstrating causality rather than correlation in human tissue\n\n### Domain Expert Position (Round 3)\nThe expert revised confidence downward to **0.62**, emphasizing:\n- Favorable druggability characteristics (enzymatic target, known structural class)\n- Significant safety liabilities from systemic eicosanoid pathway modulation\n- Unresolved translational questions between preclinical models and AD\n\n---\n\n## Dimension Scores\n\n| Dimension | Score (0-1) | Rationale |\n|-----------|-------------|-----------|\n| **Mechanistic Plausibility** | 0.78 | Well-characterized enzymology; substrate vulnerability in myelin-producing cells is biologically coherent; calcium regulation provides logical amplification |\n| **Evidence Strength** | 0.54 | Strong preclinical evidence in EAE/stroke; **critical absence of direct AD oligodendrocyte data**; human AD tissue studies lacking specificity |\n| **Novelty** | 0.71 | Represents a distinct ferroptosis subtype (enzymatic vs. iron-catalyzed) with unique cellular specificity; underexplored in AD context |\n| **Feasibility** | 0.62 | Target is druggable (enzymatic class), but blood-brain barrier penetration for",
