已完成本轮聚合：
- 通过 PubMed 审计到 **Atg5 过表达小鼠**存在直接寿命正例（PMID 23939249）
- 将 **autophagy** 归入“蛋白稳态/自噬/线粒体”轴里的**第三个高杠杆长寿瓶颈候选**
- 同时补写了可复用记忆：**Autophagy is a baseline-positive mammalian longevity node**
<next_focus>root 下一个仍待推进的分支：围绕 autophagy 继续区分“真正可转化的寿命干预”与“仅有机制正例”的边界，优先找成年哺乳动物中更直接、更可干预的自噬增强策略。</NEXT_FOCUS>
