A puppet's two doors
Given: START choices KITE (outlined diamond with tail) and CAVE (arch); keys state those names. Rule KITE→PAGE A, CAVE→PAGE B. PAGE A says “The puppet watches a pretend kite”; PAGE B says “The puppet sees a pretend cave”. Back→START. Job / invitation: Help a reader choose one fictional scene. “Which door do you want?” Worked: KITE selects A by its rule, not because A sits on the left. CAVE selects B. Back returns both choices. A reader reaction, a real kite, weather and a visit are unknown. Next: Move the paper A card to the right and re-read the unchanged KITE→A link. If location was being used as the key, add a literal A label and trace the written rule.
