   Scheduled nightly check failed: Linux / all optional features.

   Verification status

   Reproduced. This is a real scheduled CI run, not inferred from
   reading code. Revision: 16ed13de24f30c2b3c7243f309675d0bf027caac. Run: https://github.com/LASTRADA-Software/morph/actions/runs/39570393171

   Real output

   Job: Linux / all optional features (nightly, clang)

   What would change the verdict

   This issue closes automatically the next time this job's scheduled
   run passes (see .github/workflows/nightly-slow-checks.yml's
   reconcile-issues job, matched by the nightly-check:all-features label
   below). Re-opens itself in the same way if it fails again after
   that.

   Triage: the failure changes from night to night; last night it was one Qt WebSocket timing check on clang only

   Measured from the job logs of the last four nightly runs. Not reproduced locally.

   Run	Failing tests (clang leg)
   39394274700	gallery_local_offscreen (gcc too)
   39570393171, 39749154902	two qt_quick table rescans, qt_quick_qmllint (gcc too)
   39925492763 (f13c29a97)	only #3791 morph::qt::QtWebSocketBackend: a client deadline stops the server's Task handler; the gcc leg passed

   Last night's failure:

   tests/qt/test_qt_websocket.cpp:2864: FAILED:
     CHECK( wsParkProbe().stopped.load() == 1 )
   with expansion:
     0 == 1
   test cases: 1 | 1 failed
   assertions: 7 | 6 passed | 1 failed
   

   #1037 and the PRs before it fixed the earlier causes. The remaining one appeared once, on one compiler, and was 99% of 4646 tests in. That fits a timing assertion, a CHECK that the server's suspended Task handler had already seen its stop. It could also be a real ordering bug in how a client deadline reaches the server over Qt WebSockets, and the log can't tell the two apart.

   Verdict: unverified. A real stop that sometimes isn't delivered would be a defect in src/include/morph. A check that reads stopped before the stop has propagated would be a test fix. Deciding needs the test run in a loop under load (--repeat until-fail) and a read of what the test waits on before line 2864.

   Would change the verdict: a local reproduction showing stopped == 0 after the handler's coroutine has finished means a library bug. If the check passes once it waits for the stop to propagate, it's a test fix and this closes on the next green nightly.
