Goal: if approved, observe one slow flat passage and record exact result/source/conditions; otherwise bound a model statement. Proposed codes: AC9SFU02, AC9SFI02, AC9SFI03. Prepare: passage-record, adult-approved setup, Day 52 before prediction or NOT RECORDED, Card 53.
- Safety/source · 3 min. Adult verifies date, fixed broad lines, object edges, clear table, access and consent. Stop if setup changes or is unsafe; paper-only is valid reasoning work.
- Revisit · 4 min. Read the actual prior prediction unchanged or NOT RECORDED. Model P remains fiction and cannot supply an actual prediction/result.
- Demonstrate · 5 min. Adult gently slides the approved broad object once from marked start, flat and unforced; children observe or receive neutral attributed ADULT REPORT. No speed race or repeated pushing.
- Child record · 7 min. Card 53 asks for exactly INSIDE WITHOUT TOUCHING / TOUCHED A LINE / STOPPED BEFORE / UNKNOWN, with actual source/date/orientation. If no actual try, enter NOT TESTED and describe only P's marks.
- Check · 4 min. Ask whether a drawing alone or a different object would prove the same result. Child names one condition and one unknown.
- Exit · 2 min. Keep the record privately; do not call this a general shape law.
