 ## Windows 兼容性
 
-项目使用 Win32 API 和静态链接 MSVC 运行时。建议用 Visual Studio 2017 的 `v141_xp` 工具集构建，目标为 Windows XP SP3 及以上；实际下限还取决于读卡器、扫码墩驱动及医保厂商 DLL 的支持范围。

-`operation_trace_enabled` 控制流程日志，开发期默认为 `true`。`operation_trace_include_sensitive` 控制是否记录姓名、身份证号、卡号、医保码和 `ecToken`，开发期默认为 `true`，正式环境应设为 `false`。日志写入 `logs/operation-YYYYMMDD.log`。
