One-click START-UP resurfaces the last session — what shipped, the resume note, and the open board ranked easiest-first. CLOSE-OUT snapshots this session into a stamped, durable record any lane can resume from. Backed by the live mcp_session_resume and mcp_closeout routines.
Where we left off: the newest closed session and the current open board.
Summarize what shipped; we write a stamped pure_sessions row + resume key.
