Boundary
Original ordinary child script, not held-source answer coaching. A source read-aloud for an assessment must read the exact neutral case body and prompts without the teacher criteria/models.
Delivery
Adult may read, sign or present text/pictures in chunks; optional candidate narration later only after a real listen. No generated recording exists in this proposal. Pause/repeat/skip/stop choices are explicit; words also available in full print.
Whole original script
