# 检查点：#66 / R3-02 积压断开已推送

## 完成
- 分支 `feat/fix-r3-66-disconnect` HEAD `a14ca0d`，已推送 origin，未合 main。
- 带断开下行：本帧 OnPacketSent（packet id / 载荷）等待，去掉连接级 sentPub。
- Shutdown：ctx 未取消时先 waitConnsQuiet（downCh + wirePending），再 DisconnectClient 发 0x8B，waitConnsGone；已取消则发完即 Close。
- DEVIATIONS 追加「复审修复 R3-02」。Gitea #66 已评论。

## 验证
- `go test ./internal/broker/` 通过
- `go test ./cmd/nixmsg/` 通过

## 给下个会话
- 可 rebase origin/main 后由总控合入；不要合 feat/fix-3-downlink-deadlock。
