+     machine configuration links
+
+Current five-axis switchkins status:
+
+1. Vendored LinuxCNC `5axiskins`, `xyzac-trt-kins`, and `xyzbc-trt-kins`
+   sources are compiled and probed natively.
+2. Vendored LinuxCNC sample machine assets now cover bridge-mill,
+   table-dual-rotary, and table-rotary-tilting INI/HAL/tool/demo/remap
+   files.
+3. `M428`, `M429`, and `M430` remain LinuxCNC `REMAP` entries backed by
+   vendored LinuxCNC NGC subroutines; do not replace them with standalone
+   M-code handlers.
+
+Next work:
+
+1. Route vendored LinuxCNC remap lookup/execution through the standalone
+   interpreter harness for NGC remaps.
+2. Connect the standalone HAL adapter so LinuxCNC `M68`/`M66` remap
+   synchronization updates and reads `_hal[motion.switchkins-type]`.
+3. Add a native machine-session harness for `xyzac-trt` and `xyzbc-trt`
+   programs that switch `M429 -> M428 -> M429`.
+4. Export the validated switchkins/remap status through the WASM SDK and INI
+   panel without adding JavaScript CNC semantics.
