/**
 * Teach-question arrival states (owner ruling, scroll-honesty round
 * 2026-09-25). Applied DURING RENDER before the first paint — the bug was
 * the stale expanded=true left by the previous question painting one
 * frame of the open question: the dock measured itself tall, reserved that
 * height permanently (fold immunity refused the give-back), and the
 * transcript scrolled as if the collapsed question had opened.
