mitochondrial-inflammatory decoupling therapy emerges as the most viable hypothesis, scoring 0.61 due to strong mechanistic plausibility and evidence base from perinatal asphyxia studies, despite safety concerns about disrupting protective stress responses. Temporal microglial state switching (0.57) and epigenetic memory reactivation (0.52) follow as the top three candidates, all benefiting from novel approaches to microglial dysfunction but suffering from feasibility and safety limitations identified by the Skeptic's rigorous critique. The Expert's assessment particularly highlighted regulatory challenges for epigenetic approaches and delivery obstacles for microbiota-based interventions.\\n\\nCritical knowledge gaps emerged around the mechanistic connections between early-life stress and late-onset neurodegeneration, with most hypotheses relying on correlational rather than causal evidence. The debate revealed that while neuroinflammation and microglial priming represent validated therapeutic targets, the proposed interventions require substantial validation of their underlying assumptions - particularly around the reversibility of developmental programming, the specificity of targeting approaches, and the safety of disrupting evolutionarily conserved stress-inflammatory coupling mechanisms. The bottom-ranked hypotheses (microbiota engineering at 0.36) suffered from fundamental feasibility issues and lack of mechanistic validation for proposed gut-brain connections.\"\n}\n```",
