Task lane questions/actions are now saved to a pending_task_lane JSONB column on ai_sessions, restoring them on session switch or page reload. Partial submit no longer force-clears the lane — the AI response controls what stays. Also removes redundant "New Session" button from the sidebar (dashboard already provides this).
