"""AZ-839 AC-9 — integration test: fixture produces a real :class:`PopulatedC6Cache`.

Gated by ``RUN_REPLAY_E2E=1`` AND ``@pytest.mark.tier2`` per the
AZ-839 task spec. The work the test asserts is the fixture's
contract; the fixture wiring itself lives in
``tests/e2e/replay/conftest.py::operator_pre_flight_setup`` and the
algorithmic correctness is covered by
``test_operator_pre_flight_driver.py`` against stubs (AC-8).

This test exists so AC-9 has a concrete pytest entry point. Other
end-to-end consumers (AZ-840 e2e orchestrator test; AZ-841 un-xfail
of the AZ-777 Tier-2 tests) chain off the same fixture.
