- /agent [filter] lists the run's agents (glyphs, elapsed, task) via the native selector and switchSession()es to the agent's own session file - run is restored in the agent session by deriving the run id from the session file path (<stateDir>/runs/<runId>/sessions/...) - main session file recorded in the run manifest so /back works even after a reload while viewing an agent chat - widget re-attach timer guard on session switch
