# 消息线 M2–M4 完成
|
||
|
||
- 分支：`feat/m-delivery`
|
||
- 工作树：`e:\code\NixMsg-wt\m2`
|
||
- 基于：`origin/main` `d357082`
|
||
- 提交：`9b053fd feat: 实现消息分发推送确认撤回与启动恢复`
|
||
- 验证：`task check` 通过（含 message 包表驱动测试：宽限、保留到期、确认超时两种、撤回竞态、防重、启动恢复等）
|
||
- DEVIATIONS：已写「消息 M」M2/M3/M4 节，保留其他线节
|
||
- 未接真实 MQTT：`Downlink`/`ConnRegistry` 可注入；测试用 `RecordingDownlink`+`MemoryConns`；未改 `cmd/nixmsg`/`wire.go`；调度/清理循环需接线方调用 `DispatchDue`/`PushPending`/`CleanupOnce`
|
||
|
||
## 给下个会话
|
||
- 总控按第 7 节审阅后 ff-only 合并；本分支已推送、工作区干净
|
||
- 接线：握手/断线调 `OnHandshakeComplete`/`OnDisconnect`；`OnPublishDropped` 转 `App`；启调度与清理循环
