本轮结论：

- **未找到成年哺乳动物中“第二条”可明确归入自噬轴、且以原始寿命/健康寿命终点为核心的正例。**
- 目前仍然**只有 Atg5 过表达小鼠**这条直接、干净的成年哺乳动物寿命正例：
  - PubMed 23939249：`Overexpression of Atg5 in mice activates autophagy and extends lifespan`
  - 摘要明确写到：**median lifespan +17.2%**
- 本轮对 **Atg7 / BECN1 / FIP200 / Atg5** 的限定检索，没有冒出第二条同等级证据；检到的更多是：
  - 自噬相关机制/病理读出
  - 或者像 **spermidine** 这种“促自噬”但**不是自噬基因本身直接干预**的结果  
  这些都**不能**算作“第二条自噬轴原始寿命正例”。

因此，当前更稳妥的判断是：

> **自噬轴已经跨过“有正例”门槛，但“是否存在可泛化的第二条成年哺乳动物原始寿命正例”仍未被证实。**

<NEXT_FOCUS>继续核查成年哺乳动物中是否存在第二条自噬寿命/健康寿命原始正例，优先排查 Atg7 / BECN1 / FIP200 及其他自噬核心节点是否有直接寿命终点论文</NEXT_FOCUS>
