    - 原因：原先 12 项备注写着未穷尽仍标通过，交付说明写成「通过 23」。  
    - 备选方案：为每个未测子项补验收用例（本波不做，避免为变绿放松断言）。  
    - 影响：汇总改为通过 19、部分通过 4（F03/F08/F21/F22）、失败 0。F19 仍引用仓库内 SDK 清单、本波不重跑。

+1. **JS SDK 传输失败后须再泵发送队列**  
+   - 日期：2026-09-30  
+   - 原条款：DEVELOPMENT 第 5 节 / 附录 SDK 行为约定：发送在途失败后换新 `rid` 并重交；`id` / 正文 / `send_at_ms` 不变。Gitea #69。  
+   - 实际做法：`dispatchSend` 中 `publishUp` 抛出非协议 `APIError` 时，若未 `stopReconnect` 则清 inflight、换新 `rid` 后立刻 `drainSendQueue`；若已 `stopReconnect` 则 `finishSendErr` 结束本次 `send`。不额外再乘一次抖动。  
+   - 原因：原先只换 `rid` 并 `return`，连接未断时 `hello` 不再走，队列停泵，`send()` Promise 永不结束。  
+   - 备选方案：按 `rate_limited` 同一条的退避再泵（否决本波，连接仍在线时立即重交更贴切，且避免与已有等待叠乘抖动）。  
+   - 影响：仅 `sdk/js`；假传输失败一次后会再次上行且 `rid` 已变。
