结论：已继续补齐 LinuxCNC 源码派生的 genhexkins 与 pentakins 原生 runtime baseline，构建、vendor 同步、语义守卫和 native probe 验证均通过。

 | Realtime scheduler | TP probes seed deterministic status/config data instead of running LinuxCNC realtime process topology. |
 | Kinematics component lifecycle | Kinematics modules are initialized through LinuxCNC module entry points where native runtime probes exist, while HAL component init/ready/exit, HAL pin allocation, and RTAPI module metadata are handled by standalone shims. |
 | Go math C/C++ linkage | `genserkins` runtime probing compiles vendored `gomath.c` through a narrow C++ wrapper so LinuxCNC `genserfuncs.c` can link to the upstream Go math symbols without editing vendored source. |
+| Switchkins iterative forward | `genhexkins` runtime probing follows LinuxCNC switchkins iterative-forward behavior, including the first-call warmup path before asserting roundtrip convergence. |
 | Browser storage | OPFS remains outside the native core and is not yet connected. |
