- `libtooldata` for the native source-link runner. The wasm-safe source probes
instead compile LinuxCNC `tooldata_common.cc` with `tooldata_mmap_backend.cc`
and `tooldata_runtime_stubs.cc`.
This is not wasm-ready yet, but it proves the simulator can own and compile the
RS274 interpreter core sources directly. The next source-port boundary is to
replace each support dependency with browser-safe shims instead of pulling in
the LinuxCNC task, motion, HAL, and Python runtime layers.
The wasm-safe source manifest is `linuxcnc-rs274-wasm-source-files.txt`. The
`rs274ngc_pre` wasm link and undefined-symbol probes read their LinuxCNC source
list from that manifest so `inifile.cc`, `tooldata_common.cc`, and the
interpreter sources stay on one source of truth.
When `CNC_SIM_ENABLE_LINUXCNC_WASM_SAFE_PROBE=ON`, CMake also exposes
`linuxcnc_rs274_wasm_safe_probe_objects` and the `EXCLUDE_FROM_ALL`
`linuxcnc_rs274_wasm_safe_probe` executable. The executable mirrors the
`rs274ngc_pre` shell link probe and is built only when explicitly requested, so
the normal browser wasm artifact does not accidentally link the probe runtime.
The native runner used by this probe now recognizes simulator-owned control
lines before handing code to LinuxCNC: `M428`, `M429`, `M430`, `G43.4`,
`G43.5`, and `G49`. This keeps the direct runner aligned with the public
