    held-out(无泄漏)Hit@3 0.3125 → 0.5208(+20.8pp,+66%)。4 有效杠杆叠加协同:
    - Route A fixer 注入候选池(+4.2pp)
    - version-gated 召回过滤 grace=3(+1pp,filter 非 boost)
    - HyDE-RRF-blend(+4.2pp,破 53% 池天花板到 66%;front-load −3.1pp 证伪→改 RRF 翻案)
    - Agent 因果 rerank 叠 HyDE 富池(compound +10.4pp → 0.5208)
    
    含:reranker 训练数据流水线(iter-2 BM25+symbol RRF 负样本 + diff)、生产路径接最佳配置
    (HybridSearch inject+version-gate,demo HyDE-RRF-blend)、架构图重绘(6 层 3D + 层内关系)、
    6 杠杆证伪、组员计划澄清、held-out 结果归档。
