Paper method and evidence¶
Actor proposes, Critic checks risk, Insight summarizes findings, Skill persists knowledge, and Online returns experiment-platform feedback across retrieval, fusion and reranking.

Reported results¶
Live A/B, p<0.05. Value-based retrieval/pre-ranking Engagement1/Engagement2/Diversity +0.75%/+0.90%/+0.48%; fusion/ranking +0.62%/+0.19%/+0.06%; diversity/reranking +0.21%/+0.29%/+3.43%.
Local reproduction¶
Three rounds with up to nine ranking genomes each, validation-only Critic and isolated final test. Champion transition/content/diversity 0.30/0.35/0.35. Versus fixed manual recipe, Hit@10 +8.33%, NDCG@10 +17.34%, fresh Hit@10 +150%. Metrics. Local executable weights, not Google's scheduling API or online agent.
