D140FleetRestartArmingTest did not clear the aere.pq.* properties and the per-JVM anchor
config cache in setUp, while its twin PqFleetRestartArmingTest has done so since 20 August
2026. Without it the class is green on its own and red inside the full suite, on identical
sources, because a neighbouring class leaves an armed anchor config cached.
That is the concrete cost of keeping two copies of a test: a repair lands in one and not
the other, and nothing fails to say so.
