handoff

This skill should be used to close a session so the next one starts cold from corrected truth. Operator-invoked, gated on a retro note newer than the scope's last edit. Rewrites the primer within its budget first, then runs the status sweep (fully-resolved stories proposed for archiving, flipped only on approval) and reconciles every plan's Story Index — Focus, Next, Open, Read order, about 300 words, nothing another surface derives — confirms the index synced, and prints the one line the next session starts with. Use when the user says "/handoff", "hand off", "close the session", "wrap up the session", "prep the primer", "get the primer ready", "cold session prep", or "what does the next session start with".
