Goal: use Card E to distinguish a task from an expert claim, then transfer to new Check A. Teacher says: “The brief tells a volunteer what to do and where a question goes beyond the role.”
- 0–2: Read the brief and identify the visitor-facing action.
- 2–5: Model evidence for the “do not give advice” boundary; do not model Check A.
- 5–17: Give Check A independently. Offer the three equivalent routes below; collect initial evidence before feedback.
- 17–22: With the learner's permission, show the public key and have them revise one explanation in another colour or as a second voice note.
- 22–25: Ask what detail changed their thinking; record a next step.
Routes: write the check answers; give an oral answer with exact cited words captured by a scribe; annotate the check text and record short captions for audience, boundary and revision. Alternative domains: Day 5 swaps are after-check practice only. Optional/home: draft a fictional role card with one action and one referral boundary. Move: if a response promises expertise absent from the text, ask “Which line authorised that promise?” This is a public formative check, not a secure assessment.
