# 检查点：fix issue #5 metrics 打点（已推分支，未合 main）

## 范围
- 工作树 `e:\\code\\NixMsg-wt\\fix5`
- 分支 `feat/fix-5-metrics` → `origin/feat/fix-5-metrics`
- 提交 `b4789fc`（基线 `479a08e`）
- issue #5；**未**合并 main；**未**关闭 issue

## 完成
- `nixmsg_connections{ws|tcp}`：broker OnSessionEstablished/OnDisconnect 末尾 Inc/Dec
- `endpoints`/`deliveries_pending`/`messages_scheduled` + 写队列/哈希排队：messageLoops 每秒采样真实值
- `dispatch_to_push`/`ack` 直方图：PushPending 成功推送、Ack 成功确认时 Observe
- `write_batch_commit`：store.Queue.OnBatchCommit
- `errors_total`：uplink replyErr
- DEVIATIONS 追加 `### fix-issue-5`
- 未改 group emit / 管理锁定 / 注册 IP / fatal；避开 PublishDown 与 dissolve 回执大段

## 验证
- `go test ./internal/metrics/ ./internal/broker/ ./internal/app/message/ ./internal/store/ ./cmd/nixmsg/ ./internal/httpx/` 通过
- 未跑全仓 task check

## 下一步
- 总控审阅后 ff-only 合 main；本线勿合 main
- 与 feat/fix-3-downlink-deadlock、feat/fix-6-dissolve-receipt 合并时注意 hooks 末尾与 ack 小 diff
