- The status test imported the plugin's models after the app had mapped
them ("already defined"); it reads docker_host_status with SQL.
- The swarm-expiry count awaited inside a generator expression.
- The page test's since came from the module's NOW, so |ago said "5m 4s";
it is built at test time and the assertion checks the minutes.
