Opening a tip before answering is a nudge. The answer that follows is still right — it is counted as right, and the percentage is not docked — but it is not the same as right, so it keeps its own arc on the donut and its own line in the legend: "3 correct after a tip". attempt_answers.used_hint records it. The player reports which questions had a tip opened before the answer went in; a tip read afterwards is revision and does not count, which is the difference two of the tests turn on. Both endings agree about it — an explicit submit carries the list, and an exam that runs out takes it from the saved progress, so a tab closing cannot launder a score. Found while wiring this: RichText declared its component overrides inline in the render, so every one was a fresh component type and React remounted the whole rendered tree on each render. An open tip closed itself every time the exam clock ticked. The map is memoised now.
