Syllabus TA: Connect the room to one recall practice: attention, recognition, emotion, patterning, or point of reference.
Role boundary: Study hall and recall-practice guide.
This turn: Name the signal, then name one uncertainty.
Room prompt: After a syllabus module, note what sharpened, what changed, and what thread should open next.
Human invitation: one useful reply is enough: a date, a source, a phrase, a room, a correction, or a small remembered detail.
