+## Boundaries

+- Native and WASM source lists in this document must match
+  `linuxcnc-rs274-source-files.txt` and
+  `linuxcnc-rs274-wasm-source-files.txt` exactly.
+- Python binding modules, WASM-blocked sources, and WASM-blocked headers are
+  source coverage only.
+- They must not become browser API fields or temporary smoke parser fallback behavior.
+- Browser-hostile dependencies must remain tracked blockers until they are
+  ported, trimmed, wrapped, or replaced by source-backed browser-safe LinuxCNC
+  adaptations.
+- `test-native.sh`, `test-linuxcnc-source-link.sh`, and `build-wasm.sh` must
+  run `./check-linuxcnc-rs274-source-map.sh` before consuming generated native
+  objects, source-linked LinuxCNC objects, or browser artifacts.
+- The RS274 source-map guard validates LinuxCNC source ownership and manifest
+  drift only; it does not interpret G-code.

 The wasm-safe runtime now constructs its detached `EMC_STAT` through LinuxCNC
 `src/emc/nml_intf/emcops.cc`. The singleton follows LinuxCNC
 `src/emc/sai/dummyemcstat.cc`, and the required `NMLmsg`/`RCS_STAT_MSG`
