本轮已完成对 n116 的审计：type I interferon / JAK-STAT 目前仍应降级为“情境依赖的 inflammaging 放大器”，而不是已验证的通用长寿瓶颈。
关键证据是：PubMed 没检到明确的 IFNAR/寿命直接原始证据；现有血液系统证据只显示 basal type I IFN 对 neonatal/juvenile hematopoiesis 影响“modest”（PMID 36724510），不足以支撑把它升级成总开关。
已更新任务树：
- n116：done
- 新增兄弟节点 n120：审计 complement cascade 是否能升级为长寿瓶颈
也已沉淀一条可复用知识到记忆：对免疫轴，若只有局部/病理背景正例而缺少 wild-type healthspan/lifespan 终点，就应默认降级为上游参与者而非通用瓶颈。
