+   - 运营端通道“发送测试”必须走真实闭环：前端提交手机号和短信内容到 NestJS API，后端校验通道在线后创建 `SmsBatchTask`、`SmsMessageRecord`、`SmsSubmitRecord`，并向 Redis Stream `gateway.submit.commands` 写入真实 `SubmitCommand`；短信记录页面必须能查询到测试短信，不允许只返回占位成功或只关闭弹窗。
 2. Gateway 必须校验上游 connect/login 返回码，区分 connected、auth_failed、connect_timeout、network_error、protocol_error 等状态，并回写 NestJS 真实连接状态。
 3. Gateway 必须支持每个通道配置期望连接数，建立多条长连接，并按连接维度维护 currentConnections、lastConnectedAt、lastHeartbeatAt、lastError、reconnectCount。
    - `desiredConnections`、`windowSize` 是平台对上游通道连接池和提交窗口的运行配置，必须通过运营端通道配置页面保存到真实后端；它们不是 CMPP 标准 PDU 字段，也不是 gocmpp 的原生配置字段。

 # 第一版系统化测试进度
 
+## 2026-07-09 运营端通道测试短信闭环修复
+
+- 生产验证发现运营端通道“短信测试”弹窗仅关闭页面，未调用后端；`POST /api/admin/channels/:id/test` 仍返回 phase-4 placeholder，不创建 `SmsMessageRecord/SmsSubmitRecord`，也不写入 Gateway SubmitCommand，因此短信记录页面无记录。
+- 已修复为真实链路：前端提交手机号、内容和可选接入号；NestJS 校验通道 active 且存在在线 CMPP 连接后，创建 `SmsBatchTask`、`SmsMessageRecord`、`SmsSubmitRecord` 和操作日志，并向 BullMQ `gateway.submit.queue` 与 Redis Stream `gateway.submit.commands` 写入真实 `SubmitCommand`。
+- 测试口径同步：`TC-ADMIN-003` 增加通道测试短信闭环要求，必须能从页面/API 发起真实测试短信，短信记录页面可查询到对应记录，Gateway submit worker 按通道真实 CMPP 配置消费发送。
+- 已执行：`npm --prefix api test -- channels.service.spec.ts --runInBand`、`npm --prefix api run build`、`npm run build`。待生产部署后用指定号码做一次真实发送验证，并回查 DB/短信记录。
+
+## 2026-07-09 线上通道 CMPP 版本修复
+
+- 线上生产验证发现 3 个赛邮行业通道配置均指向 `121.40.172.212:7890`，其中 2 个已触发 Gateway 真实连接并失败，`CmppConnectionState.lastError` 为 `packetWriter.ReadBytes error: ReadBytes reads 14 bytes, not equal to 16 we expected`。
+- 生产机到上游 `121.40.172.212:7890` TCP 可连接，失败不是 API/Gateway 服务不可用，也不是网络完全不通；结合上游确认参数为 CMPP 2.0，根因定位为通道创建默认 CMPP 3.0 且运营端没有版本选择入口。
+- 已修复通道创建/编辑：运营端新增 CMPP 2.0/3.0 版本选择，默认 2.0；NestJS 通道 API 默认 `cmppVersion=2.0`，并只允许 2.0 或 3.0；Prisma `SmsChannel.cmppVersion` 默认值同步改为 2.0。
+- 测试口径同步：`TC-ADMIN-003` 要求通道协议默认 CMPP，CMPP 版本默认 2.0，且可选择 2.0 或 3.0；Gateway 连接命令必须携带真实通道版本。
+- 待复测：部署迁移后将线上赛邮通道 `cmppVersion` 调整为 2.0，并重新触发 Gateway 连接验证。

 ## 2026-07-07 企业应用通用下拉与优先队列需求补充
 
 - 已补充需求文档，明确运营端企业应用新增时选择企业必须使用通用 Select/下拉控件，企业选项来自真实企业 API，支持加载、空态和错误态，不允许静态数组或 localStorage 兜底。
