结论：新增 source-probes.tsv 映射并在 native 验证中比对 source-manifest，确保每个 vendored LinuxCNC .c/.cc 源文件都有显式 standalone 源码编译探针。

   existing INI parser harness. With this probe, every `.c` and `.cc` file
   listed in `tools/source-manifest.txt` has a native source-level compile
   check under the standalone build boundary.
+- `tools/build_native_probes.sh` now emits `build/native/source-probes.tsv`
+  while compiling vendored `*_source_probe` targets. The native verification
+  script compares that map against every `.c` and `.cc` entry in
+  `tools/source-manifest.txt`, so future LinuxCNC source additions fail
+  validation unless they also get an explicit standalone source compile probe.
