严重性: ⚠️ Medium 置信度: ✅ 较确定 问题类别: 测试覆盖 / CI 门禁 问题详情: ASCCOMM_BUILD_MC2 默认 OFF 可以避免影响存量构建，但本 PR 的核心交付物正是这个默认关闭的骨架 target。PR 中未提交显式开启该选项的 CI/build 入口，因此默认流水线通过并不能证明 mc2_client 及其链接配置被验证过。对于“只有 CMake、暂无真实源文件”的拆分式迁移，这一点尤其需要门禁兜底。 修改建议: 增加一个显式执行 cmake -DASCCOMM_BUILD_MC2=ON 并构建 mc2_client 的 CI smoke job，或接入现有构建脚本的可选矩阵；至少在迁移说明中固化本次手工验证命令，并在系列 PR 完成前保持为必跑门禁。

严重性: ⚠️ Medium 置信度: ✅ 较确定 问题类别: CMake 输入校验 / 构建可用性 问题详情: ASCCOMM_MC2_PRODUCT_SIDE 的说明中暴露了 device，但当前实现只有 host 分支。设置为 device 或任何非 host 值时，整个 target 定义会被跳过；即使 ASCCOMM_BUILD_MC2=ON，CMake 仍可能配置成功且不生成 mc2_client，用户很容易误以为构建通过。非法值同样没有报错。 修改建议: device 未实现前建议不要在 cache 字符串中暴露；或者配置期严格校验取值，未支持/非法值直接 FATAL_ERROR，至少对 device 输出明确的未支持提示。也可以用 set_property(CACHE ASCCOMM_MC2_PRODUCT_SIDE PROPERTY STRINGS host) 约束可选值。

严重性: ⚠️ Medium 置信度: ✅ 较确定 问题类别: 构建可移植性 / CMake 生成器兼容性 问题详情: 这里直接覆盖 CMAKE_CXX_COMPILE_OBJECT / CMAKE_C_COMPILE_OBJECT，并在编译规则中嵌入了 GNU Make 语法 $(notdir $(abspath <SOURCE>))。该写法依赖 Unix Makefiles 生成器；切换到 Ninja 等其他生成器时 Make 语法不会被展开，__FILE__ 宏可能得到错误内容甚至导致命令异常。另外这是目录级规则，后续同目录新增的 target（如 mc2_client_hcomm_stub）也会受影响。 修改建议: 尽量避免覆盖 CMake 内部编译规则。若目标是日志只显示文件名，优先评估编译器可用的 __FILE_NAME__、-ffile-prefix-map 或保持相对源路径等可移植方案；如果确实必须沿用 Make 展开，请在配置期显式校验 CMAKE_GENERATOR 为 Unix Makefiles，不支持的生成器直接 FATAL_ERROR，避免静默产生错误的 __FILE__。

严重性: ⚠️ Medium 置信度: ✅ 较确定 问题类别: 构建配置正确性 / C++ 标准冲突 问题详情: 仓库根目录已设置 CMAKE_CXX_STANDARD 17，这里又手动给 target 追加 -std=c++14。实际生成的编译命令会同时包含两个标准选项，且 CMake 追加的 -std=gnu++17 位于后面并生效，因此 target 实际按 C++17 编译，而不是这里声明的 C++14。后续迁入代码时，这会掩盖依赖 C++14 语义或误用 C++17 特性的风险。 修改建议: 删除手动 -std=c++14，改用 target 属性明确标准，例如 set_target_properties(mc2_client PROPERTIES CXX_STANDARD 14 CXX_STANDARD_REQUIRED ON CXX_EXTENSIONS OFF)；如果决定跟随仓库全局标准，则直接移除该选项并在文档中明确 C++17。
