本轮结论：
- 我把长寿候选放进一个统一的因果强度比较框架后，当前**最强主轴仍是表观遗传信息损失**。
- 一个简单加权评分的临时排序是：
1. **表观遗传信息损失**
2. **细胞衰老**
3. **IL-11**
4. **自噬**
- 这与现有记忆一致：
- **自噬**已经是 baseline-positive，但更像“过程性高价值节点”，还没到最强主轴级别。
- **细胞衰老**比自噬更像可清除的损伤负担，整体因果更直接。
- **IL-11**在免疫/炎症轴里很强，但仍有明显 pleiotropy 代价。
- **表观遗传信息损失**同时满足“可干预、可读出、可做年龄状态回拨”的工程属性，因果杠杆最高。
下一步最值得做的不是继续抽象争论，而是把这四个候选都压到同一张 **organism-level 证据表** 里，专门核查：
- 是否有成年哺乳动物的 **lifespan / healthspan** 终点；
- 干预是否是**直接针对该候选**；
- 证据是否足够独立、可升级。
