结论：依据 LinuxCNC canonmodule.cc、interpmodule.cc 与 py*.cc，新增 Python binding link probe，证明 7 个 non-gcodemodule blocked binding 对象可与 inert Python/runtime shims 链接；同时负向锁定 gcodemodule.cc 与浏览器 runtime canon bridge 的 Canon 回调重定义冲突，Python/remap 执行仍禁用，未扩展 smoke。 检查：./test-linuxcnc-wasm-python-binding-link.sh；./test-linuxcnc-wasm-python-c-api-symbols.sh；./test-linuxcnc-wasm-runtime-link.sh；git diff --check；./test-native.sh；./test-linuxcnc-source-link.sh。

# keeping src/emc/rs274ngc/gcodemodule.cc isolated because it defines Canon
