48d7526 widened the options dialog first-focus selector to inputs, so the new story graph switch above the menus took initial focus. Keyboard users no longer landed on the expert / work mode menus like the model picker. Restore the button-only target; the switch stays reachable with Tab.
Add a supervisor text-model selector using existing connections and a per-conversation story graph switch above knowledge settings. Hide the switch when Supervisor is disabled and enforce conversation preferences at local and remote tool execution boundaries.
Release note: Choose a dedicated supervisor model and control whether each conversation can query existing stories and experiences. Enabling graph access does not start a review or automatically insert context.
