+## 2026-07-02 00:00 原生 systemd 部署与宇通 MQTT 复验
+
+根据本次 goal 的新要求，Go 接入链路后续不再使用 Docker 部署。本轮已中断 Docker 镜像构建路径，改为 ECS 原生 Linux 二进制 + systemd。
+
+部署版本：
+
+- Git commit：`594ab2d`
+- 部署目录：`/opt/lingniu-go-native`
+- 当前 release：`/opt/lingniu-go-native/releases/594ab2d`
+- 当前指针：`/opt/lingniu-go-native/current -> /opt/lingniu-go-native/releases/594ab2d`
+
+systemd 服务：
+
+```text
+lingniu-go-gateway.service        active
+lingniu-go-history-writer.service active
+lingniu-go-stat-writer.service    active
+lingniu-go-realtime-api.service   active
+```
+
+端口确认：
+
+```text
+[::]:32960  gateway
+[::]:808    gateway
+[::]:20210  realtime-api
+```
+
+Go Docker 容器已停止：
+
+```text
+go-vehicle-gateway  Exited
+go-history-writer   Exited
+go-stat-writer      Exited
+go-realtime-api     Exited
+```
+
+宇通 MQTT：
+
+```text
+yutong mqtt client started
+mqtt subscribed broker=ssl://cpxlm.axxc.cn:38883 topic=/ytforward/shln/+ qos=1
+```
+
+说明：MQTT broker 存在短连接 `EOF` 后自动重连现象，但订阅后已收到真实数据并落 RAW。
+
+RAW 查询复验：
+
+```text
+GET /api/history/raw-frames?protocol=YUTONG_MQTT&limit=3
+
+total=3
+protocol=YUTONG_MQTT

+
+同轮回归：
