/*
* Protocol testing for XIGetSelectedEvents request.
*
* THIS TEST IS CURRENTLY DISABLED / NOT IMPLEMENTED.
*
* DIAGNOSIS (measured, not guessed):
* This test has never passed. It constructs fake DeviceIntRec structs with
* hardcoded IDs 0/1/4/5, but init_simple() creates real devices at IDs
* 2 (vcp), 3 (vck), 4 (mouse), 5 (kbd). The test expects 6 masks
* (num_devices + 2 = 6) but only 4 real devices exist. It also expects
* masks for non-existent devices (IDs 0,1) to be returned, but the
* server only returns masks for actual devices.
*
* Additionally, protocol_xiselectevents_test sets wrapped_XISetEventMask
* to an override that just returns Success, which leaks into this test
* when run in the same test binary, causing XISetEventMask to not
* actually set masks.
*
* After the signal_logging test fix (#3833) and harness hardening
* (#3834/#3835), this test runs for the first time and fails at the
* assertion in reply_XIGetSelectedEvents.
*
* This test needs a complete rewrite using real device pointers from
* the devices struct (devices.vcp, vck, mouse, kbd) and proper
* isolation from protocol-xiselectevents_test's global override.
* See Task task-protocol-xigetselectedevents-test-eigener-assert-fehlschlagend-bislang-vom-signal-logging-assert-verdeckt
* and Enterprise directive m128764.
