 - Fast DDS/RMW participant 实际创建：通过，输出 `RMW participant created`。
 - 环境摘要：Domain `22`、RMW `rmw_fastrtps_cpp`、本地 DDS 地址 `.164`。
 - 首次从 PowerShell 直接拼接远端 `python3 -c` 时，引号在 SSH 边界被破坏，Python 在读取 XML 前即报 `SyntaxError`。该失败与 XML 内容无关，未修改配置；改为通过 WSL Bash 和 stdin 传入验证程序后，相同验证完整通过。

+验证结果：
+
+- `bash -n`：通过。
+- XML well-formed：通过。
+- Fast DDS/RMW participant 实际创建：通过，输出 `RMW participant created`。
+- 环境摘要：Domain `22`、RMW `rmw_fastrtps_cpp`、本地 DDS 地址 `.151`、peer `.164`。
+- WSL 提交命令在工具等待窗口内没有返回，但后台提交随后正常完成；复核 commit `b8840ec9` 只包含两个批准的配置文件，原有 `.vscode` 暂存内容未进入该提交。
