- The PythonPlugin shim must preserve the `TOPLEVEL` missing-path `PLUGIN_BAD_PATH` edge from `src/emc/pythonplugin/python_plugin.cc` before reporting the browser-safe disabled Python runtime status.
- The PythonPlugin shim must preserve `PATH_PREPEND` and `PATH_APPEND` tilde-expansion failure statuses from `src/emc/pythonplugin/python_plugin.cc` and `src/emc/ini/inifile.cc` without executing Python path mutation in browser-safe probes.
- The PythonPlugin shim must not execute `bp::exec`, `bp::exec_file`, or real
Python callable dispatch; `PyObject_Call` is an inert C API symbol only.
