Target/codes: Use two attributed feature meanings to pose a respectful question before changing a shared feature; AC9HSFS01, AC9HSFS03 and AC9HSFS04 partial, AC9HSFK03 fictional concept rehearsal only.
- Settle/purpose · 3 min. Place B/C beside D. This is a fictional question about a shared feature, not a physical-game rule.
- Read source · 4 min. Reread Bo's need for paper-model space and Ada's book-looking reason; neither claims all users.
- Model inquiry · 5 min. Ask “If a table were closed, what might Bo need?” Note the conditional. A choice board does not test a replacement space.
- Child response · 7 min. Child asks one question that includes both a proposed change and a person/use that might be affected, plus one missing perspective.
- Check/respond · 4 min. If child guarantees benefit or harm, ask what observation would establish it and whether one exists.
- Exit · 2 min. Keep the question for a future-source selection.
Next move: Preserve conditional “might” until an actual source reports a result. See routes and swaps.
