Target/codes: Tie one cue/sequence change to observed reader feedback or a named unknown; AC9TDEFP01.
- Welcome · 3 min. User difficulty is information for the designer. No reader trial is also an honest unknown.
- Notice source · 4 min. Reopen the Day 97 reader record, with exact words/pointing or NOT TRIED.
- Model · 5 min. Conditional example: “If the reader skipped CHECK and chose a numbered mark, I might move the STATUS word before the mark question. I would need another willing try to know whether it helps.”
- Child design talk · 7 min. Child changes one prompt word, sequence, source label or accessible signal for their user, names the evidence/unknown, and proposes a next ordinary reader question. A re-try, if approved, has a new record.
- Check/respond · 4 min. Record feedback/unknown → change → next observation. If the change simply decorates, ask how it helps the named reader check source/status.
- Exit · 2 min. “I changed ___ because ; next I would check .”
