test_compose asserts the new decnet.topology.* labels land on both base deckies (role=base, no service marker) and service fragments (service=true). The stub docker client in test_deploy grew a filters kwarg so it keeps matching the real .networks.list(filters=...) call signature now used by the deployer.
