Poweradmin\Application\Service

The collaborators a controller is built from. In production Kernel::controllerEnvironment() derives one from the booted context (config file check, database connection, session authentication); a test passes one straight to the constructor with stubbed services, most usefully a stub ControllerServiceFactory, which the create*() accessors on BaseController all route through. Both paths construct the controller the same way.

The services controllers ask for, split by concern into five factories that each memoize their per-request instances. The flat accessors below delegate to them so call sites and test doubles keep one entry point.
