# ImGui scope changes (gui_2.py) must be verified with scripts/check_imgui_scopes.py

From `conductor/product-guidelines.md` §"Code Standards & Architecture":
- **Mandatory ImGui Verification:** All changes to the GUI (`gui_2.py`) MUST be verified using the custom AST linter (`scripts/check_imgui_scopes.py`) to ensure all ImGui scopes (begin/end, push/pop) are properly matched. Developers should prioritize the use of `src/imgui_scopes.py` context managers (`imscope`) over manual push/pop calls.

From `conductor/workflow.md` §"Code Style":
- **ImGui Defer Patterns:** Use `imscope` context managers or `_render_window_if_open` dispatch helpers to prevent resource leaks and keep the main loop flat. See `conductor/code_styleguides/python.md` for details.
