本轮完成了对自噬轴“第二条成年哺乳动物原始寿命/健康寿命正例”的逐项审计，并得到：
- PubMed 重新确认了 **Atg5 过表达延寿** 这一条明确原始正例：**PMID 23939249**。
- 进一步逐项核查 **rapamycin / spermidine / trehalose / general autophagy induction** 后，**没有确认到第二条可算作成年哺乳动物寿命/健康寿命终点的原始正例**。
- 因此，当前最稳妥结论仍是：**autophagy 是 baseline-positive mammalian longevity node**，但**还不足以升级为“已有多条独立原始正例支持的普适寿命延长策略”**。
我已把这条边界写回长期记忆，并将子任务标记为失败，避免把“没检到”误写成“已证实存在”。
<NEXT_FOCUS>转向寻找自噬轴之外的下一个高杠杆长寿瓶颈候选，优先选择能被成年哺乳动物原始寿命/健康寿命终点直接审计的方向</NEXT_FOCUS>
