Research direction
Start with the proposed entry point in ui/hooks/useControllerSelector.ts and review the Issue 3.1 dependency for the selector context. Define the ControllerSelector type and cover single-controller, multi-controller, and fallback behavior with unit tests; done means the hook narrows subscriptions when controllerDeps is set and otherwise uses all controllers.
