-1. **推送 worker 漏唤醒：定时分发回执、超限后续、撤回腾窗**  
+1. **JS SDK 传输失败后须再泵发送队列**  
    - 日期：2026-09-30  
-   - 原条款：Gitea #65；推送 worker 只在 `WakePush` 时跑一轮 `PushPending`。  
+   - 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：`dispatchDueBatch` 本条已分发时除 pending 接收方外始终 `WakePush` 发送方；`PushPending` 遇 `too_large` 等跳过且本轮未占满窗口时再 `WakePush` 当前接收方（不在同一次递归扫表）；`Recall` 成功改成 `recalled` 的接收方各 `WakePush` 一次，已推送撤回仍走 `flushRevokes`。不改 `PublishDown` 签名。  
+   - 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：终态回执、超限后的后续 pending、撤回腾出窗口后都依赖再唤醒，否则空闲在线端收不到。  
+   - 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：在同一次 `PushPending` 里循环扫完整 pending 表（否决，指令要求合并唤醒下一轮）。  
+   - 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 `internal/app/message/`；相关单测见 `review_r3_65_test.go`。
+   - 影响：仅 `sdk/js`；假传输失败一次后会再次上行且 `rid` 已变。
