/**
 * THE DRY-RUN COUNT, AND THE REPAIR — [central-ticketing] #938.
 *
 * The first question #938 asks is a number: how many rows on prod carry
 * `merged_into_id` with a status other than `merged`. That number decides
 * whether the office corrects them one at a time from the badge or whether a
 * deploy re-marks them all, and there was no way to ask for it that did not
 * involve typing a raw UPDATE-shaped statement into tinker on the production
 * box. So `--dry-run` is the default and is the point of this command:
 *
 *     php artisan ticketing:repair-merged --dry-run    # count + list, writes NOTHING
 *     php artisan ticketing:repair-merged --force      # re-mark them all
 *
 * `--force` is required to write, rather than `--dry-run` being required not
 * to. A repair command whose bare form repairs is one fat-finger away from
 * being the incident it was written to clean up after.
