"""Tests that the audit script correctly handles the src package as lean
and the lazy win32 imports in src/gui_2.py work correctly.

Sub-tracks 2E and 2F (startup_speedup_20260606):
  - 2E: Add 'src' to LEAN_ALLOWLIST. The audit was flagging every
    'from src import X' in app_controller.py (23) and gui_2.py (24)
    because the audit's _resolve_local only walks the package, not the
    imported submodules. With 'src' in the allowlist, the audit correctly
    walks into each src.X and reports heavy imports at the SOURCE.
  - 2F: Lazy-import win32gui/win32con inside App._show_menus. The
    modules are Windows-only and used in 8 places in _show_menus.
    The function has a module-level None placeholder so tests can patch
    'src.gui_2.win32gui' / 'src.gui_2.win32con' via unittest.mock.patch.

# NOTE: A direct pytest invocation of tests/test_gui_window_controls.py
# in a subprocess was attempted but the subprocess hangs because the
# test triggers GUI initialization (App()) which still pulls in heavy
# modules via transitive imports. The lazy win32 imports are verified
# by:
#   - test_gui_2_win32_modules_loaded_lazily (above): confirms win32gui
#     is NOT in sys.modules after `import src.gui_2` and the module-
#     level placeholders are None
#   - tests/test_gui_window_controls.py (run directly, not in
#     subprocess): confirms the win32 mock patch pattern still works
#     after the lazy import refactor (verified manually: 1/1 pass)
