机架管理前后端（rack/）：FastAPI + SQLite + Vue3，经统一门户上线
- 后端 prrack：MQTT（phonerail-backend @ 127.0.0.1:1884）↔ 遥测入库 / 事件增量同步 / WebSocket 推送； 命令白名单 + 重传同 seq；审计记门户 X-Auth-User（只绑 127.0.0.1，main.py 拒绝非回环）。 - 自动恢复：只看电流（平线 / 过低，服务器够不到手机 adb），先长按电源再断电重启， 每小时限次后停手；默认逐台关闭。adb 探活接口 recovery.Prober 预留。 - 前端：总览 / 板子页（五路操作、电流电压曲线）/ 事件 / 操作记录 / 自动恢复；手机宽度可用。 - 部署 deploy/deploy.sh：服务器 Python 3.8 上先跑测试再替换；systemd phonerail-rack，每日备份。 - 门户应用 id 16、key rack（phonerail 已被需求文档站占用），授权 admin + staff。 测试 26 例（本机 3.14 / 服务器 3.8 均过）。线上板 b81f3fc9c8bc 在线，WS 经门户 101 + 1 条/s 遥测。 Co-Authored-By: Claude Opus 5.5 <[email protected]>

"""模拟板子：说和真板一样的 MQTT 协议（firmware/main/mlink.h + cmd.h），给测试与本机开发用。
|
||||
|
||||
它**不是**固件的第二份实现，只模拟服务器看得见的那部分行为：
|
||||
· 回应格式、seq 判重（按值、窗口 32）、空槽拒绝、越界拒绝；
|
||||
· 遥测（status 的形状）、retained 上线消息；
|
||||
· 事件日志（带序号，`events` 分页 8 条）；
|
||||
· 手机的电流：正常 = 在 300~900 mA 间游走；卡死 = 一条平线；关机 = ≈0。
|
||||
断电重启 / 长按电源键会让「卡死」的手机恢复正常 —— 自动恢复的测试靠这个。
|
||||
时间由调用方推进（`tick(now_ms)`），测试因此是确定的。
