/**
 * The Fix Semi-Final Pairings admin action.
 *
 * Elimination Final n feeds Semi-Final n, but brackets advanced before that was fixed
 * crossed the two winners, and nothing re-runs advancement — a completed match cannot be
 * re-submitted from the UI.
 *
 * It moves qualifier slots only — no scoring runs, so nothing reaches Discord.
