参考所有分组，完成尽量多的内容：锁定RS274源码映射结论

结论：补齐 WASM header、blocked-header、metadata 的 source map 文档闭环，并把 manifest/source-map 同步检查接入 native 必跑路径；未扩展 smoke 功能。

+### WASM-tracked headers
+
+These LinuxCNC headers are tracked by the wasm manifest because the
+browser-safe source-link probes compile against them or shim their declarations:

+- `src/emc/rs274ngc/array1.hh`
+- `src/emc/rs274ngc/interp_array_types.hh`

 ### Browser-hostile dependencies to replace
 
 - Python/Boost.Python remap and named parameter hooks.
