-   To promote warnings to errors (fail the test run), add to pyproject.toml::
+   The plugin also wraps ``subprocess.run`` at runtime to catch real
+   subprocess calls that leak through transitive call paths (e.g.
+   ``CliRunner.invoke(main)`` → ``main()`` → ``update_doc_versions()``
+   → ``subprocess.run()``).  If a test spawns a real subprocess without

 2. **As a standalone CLI** (for CI gates)::

+6. **Module-level heavy imports** — importing ``httpx``, ``ansible``,
