Reconstruct the sprint on a long wall: events, decisions, surprises, and how people felt at each point. The richest picture of what actually happened — worth the longer timebox.
A long line from sprint start to end; mark the days.
Everyone posts events, decisions, and surprises where they happened.
Mark high and low feelings along the line — a mood curve emerges.
Walk the wall together; stop at clusters and mood dips: what happened here?
Name the patterns; agree 1–3 owned actions.
