The test had a pre-existing race: it monkeypatched _rebuild_rag_index and _flush_to_project to no-ops, which made _do_project_switch complete synchronously inside the io_pool worker. By the time the test's _api_generate call ran is_project_stale() was already False (the worker had cleared _project_switch_in_progress), so the 409 contract was never exercised. Fix: replace the no-op lambdas with `lambda: time.sleep(0.5)`. This keeps the worker busy for 500ms, which is more than enough window for the test to call _api_generate and observe the stale flag. _wait_for_switch then drains the rest of the work. Also: removed the @pytest.mark.skip marker; the underlying issue is now fixed in the test. Verified: 9/9 in tests/test_project_switch_persona_preset.py pass (previously 8 passed + 1 skipped).
