Target: represent an incomplete supplied record faithfully; partial AC9TDIFK02. Ready: D, incomplete guide, A/C separate.
- Welcome · 3 min. “This guide forgot to record one location. Can we notice the gap?” No pretend danger or race is needed.
- Model · 4 min. Read D's three exact entries. BOX's position is NOT RECORDED. That does not mean no box exists, and it does not say RIGHT.
- Together · 5 min. Compare “the record doesn't tell us” with “we checked and found it here”. No current check has been supplied. A guess can be labelled a guess without becoming an entry.
- Child task · 7 min. Child represents D with a clearly labelled NOT RECORDED box entry, then chooses a useful next step: ask for a checked entry, inspect an approved actual current set, or leave the record incomplete. A planned next step is still a plan.
- Notice · 4 min. Preserve whether the child kept uncertainty visible. If an old A location is copied, ask which source actually supplies that information after capture; do not fill D from memory.
- Close · 2 min. “A clear gap is more useful than an unlabeled guess.” Keep the dated incomplete record separate from any actual update.
