🎤 Stakeholder Validation Board

Teams assemble a concise gallery-walk board or slide set with a before-and-after entrance map, collision diagrams, stakeholder quotes, revision history, and a final recommendation for testing with facilities staff, safety committee members, law enforcement, or a collision-repair professional. The validation round functions as a performance checkpoint: teams explain how user evidence and momentum-based reasoning shaped the revision path, then capture final comments for Phase 4 exhibition updates. Students close with a short voice reflection on how feedback changed their recommendation and what still needs testing.
