// production race-count requirement (`len(races) >= 10`) honoured.
// The owner creates an enrollment-open game, ten pilots redeem
// per-game invites, admin force-starts, and the test waits for the
// runtime record to reach `running`. It then triggers force-stop and
// asserts the runtime exits the active set.
