本轮完成了对成年哺乳动物“自噬增强”寿命/健康寿命原始正例的系统扫描，结果仍只稳固支持一条正例：Atg5 过表达小鼠；对 TFEB、Beclin1、广义 autophagy enhancement、spermidine 等组合未检出可确认的第二条成年哺乳动物原始正例。因此，当前最稳健表述仍是 **baseline-positive mammalian longevity node**，还不能升级为普适长寿策略。
我也把这一结论更新进长期记忆，强化了两个可复用教训：
- 检索必须同时约束 **干预 + 终点**
- 只有单一原始正例时，先保留为 baseline-positive，不要过早泛化
<NEXT_FOCUS>在自噬轴之外，继续寻找“第二个同样有成年哺乳动物原始正例支撑”的长寿瓶颈候选，并优先审计是否存在更强的类效应证据</NEXT_FOCUS>
