+## GoldWave menus and combo boxes
+
+The helper supplies both 32-bit and 64-bit menu hooks. Check both architectures:
+
+```sh
+xvfb-run -a python3 tests/menu_integration.py --fixture menu
+xvfb-run -a python3 tests/menu_integration.py --fixture menu --32-bit
+xvfb-run -a python3 tests/menu_integration.py --fixture controls
+xvfb-run -a python3 tests/menu_integration.py --fixture controls --32-bit
+xvfb-run -a python3 tests/menu_integration.py --fixture goldwave --goldwave-exe /path/to/GoldWave.exe
+```
+
+The controls fixture changes a combo selection without emitting a value
+WinEvent. It requires the new value while focus stays on the combo, with the
+same source identity as its focus event. This catches both missing polling and
+Wine's misleading focus notifications for the combo's internal list.
+
+The optional GoldWave 5.70 fixture copies the application directory into a
+temporary directory and uses a fresh Wine prefix with Force screen reader
+mode enabled. It waits for the actual main form, dismisses the first-run
+settings prompt in the test copy, and drives Alt+F, menu arrows, Ctrl+O and
+file-type combo Down/Down/Up using SendInput. On October 11 it received File,
+New, Open and unavailable Close menu events, followed by Wave/MPEG Audio/Wave
+value updates without tabbing away. This confirms helper events through the
+private D-Bus recorder; audible speech and physical braille need live checks.
+
+Install all five helper artifacts together, restart Cthulhu, and reopen
+GoldWave. With screen reader mode enabled, check File and other menus with
+Alt and arrows, then Escape back to the previous control. In Open Sound,
+check Files of type and Look in with arrows: expect the new value immediately
+in speech and braille, with keyboard focus remaining on the combo. Repeat
+Tab/Shift+Tab and Alt+Down/Escape dropdown opening and closing.
