What the merge guarantees
- Your existing calls come with you
- Accuracy, points and streak carry across intact.
- One prediction and one score per question
- One transaction. It cannot end with two of either.
- Opening the link twice changes nothing
- Idempotent. On a clash the earliest valid answer stays canonical, audited, no points moved.
