 # Wine control integration
 
+## Reader endpoint selection
+
+After building, run these checks sequentially on private displays:
+
+```sh
+xvfb-run -a python3 tests/controller_integration.py --build-dir build
+xvfb-run -a python3 tests/controller_integration.py --build-dir build --reader orca
+xvfb-run -a python3 tests/menu_integration.py --build-dir build --reader orca
+xvfb-run -a python3 tests/menu_integration.py --build-dir build --reader orca --fixture edit
+xvfb-run -a python3 tests/review_integration.py --build-dir build --reader orca
+```
+
+The controller test drives the helper through a native Windows NVDA RPC client.
+It verifies speech, cancellation, braille, SSML status forwarding, reader loss,
+invalid reader values, and startup refusal when only the unselected service
+exists. Both service names are owned while the selected reader handles requests.
+The menu/editor and review tests also accept `--reader cthulhu`; omit the option
+to check existing default behavior. Review checks reject callers even when they
+own the unselected service, then replace the selected service owner and verify
+registration and capture access move to the new owner. Its provider object path
+and interface remain the same for both readers.
+
+These tests supply recording services implementing the Wine protocol; they do
+not run Orca or prove audible speech or physical braille. Stock Orca still needs
+the reader-side methods and helper lifecycle described in the
+[integration contract](../README.md#reader-selection-and-orca-integration).
+Before submitting, check Cthulhu's ordinary Wine menus, editor arrows, repeated
+characters, selections, deletion, protected fields and keypad review with live
+speech and braille. When an Orca integration exists, repeat those workflows
+with `--reader orca`, including return to Linux controls and reader restart.
