           - route 健康页已经能把 `cooldown / failing / healthy / disabled` 四态聚合出来
           - 健康页与真实 `resolve` / `failover` 日志已经对齐
           - `P2-T4` 可以开始把这些验证步骤收敛成标准化验收矩阵与脚本
+      - 2026-05-29 已完成 Phase 2 / `P2-T4 真实验收矩阵`
+        - 提交：
+          - `94913400 feat(routing): add route acceptance matrix scripts`
+          - `5689286f fix(acceptance): align route model list parsing`
