 ### YNX-1105 编写失败路径测试矩阵

 **目标**
 - 系统性覆盖 pairing/auth 失败路径

 - 已扩展 `Yonexus.Client/tests/state-and-rules.test.ts`
   - SR-06：损坏的 client state 会抛出 `YonexusClientStateCorruptionError`
 - 已同步更新 `tests/failure-path/MATRIX.md`，标记 PF-09、SR-01、SR-05、SR-06 为已覆盖
+- 已新增 `Yonexus.Server/tests/connection-heartbeat-failures.test.ts` 补齐：
+  - CF-03：重复认证连接晋升时关闭旧连接并保留新连接
+  - CF-04：协议版本不匹配时返回 `UNSUPPORTED_PROTOCOL_VERSION` 并主动断开
+- 已新增 `Yonexus.Client/tests/runtime-flow.test.ts` 恢复场景：
+  - SR-03：客户端带既有 secret + keypair 重启后直接进入 auth flow，不重新配对
+- 已同步更新 `tests/failure-path/MATRIX.md`，标记 RP-02、CF-03、CF-04、SR-03 为已覆盖
 
 **待完成**
 - AF-04：当前实现未单独暴露 `invalid_secret` 分支，需先决定是否保留该错误码语义
-- RP 其余触发场景
-- CF / HF / SR 其余边界场景测试（例如 duplicate connection、version mismatch、server/client restart with active session 等）
+- RP-03 / RP-04：管理员主动撤销与 key rotation 语义仍未实现
+- PF-08 / PF-10、CF-01 / CF-02 / CF-07、SR-02 / SR-04 等剩余边界场景测试

 ### Current Notes
 
 - AF-04 (`invalid_secret`) 仍未单独覆盖：现有实现把“错误 secret 导致的验签失败”统一落到 `invalid_signature`，是否拆分错误码仍待确认。
