未完成
初级参考 完整示例代码供参考，建议自己理解后重新输入

    for did, ts, cmd, errors in cases:

        print(did + ": " + json.dumps(resp, ensure_ascii=False))

输入
solve()
期望输出
RPI-001: {"ack": true, "server_ts": 1748736000, "device_id": "RPI-001"}
ESP-001: {"ack": true, "server_ts": 1748736001, "device_id": "ESP-001", "cmd": {"type": "set_threshold", "params": {"value": 15.0}}}
ARD-999: {"ack": false, "server_ts": 1748736002, "device_id": "ARD-999", "errors": ["unknown_device"]}
