 * as GetCurrentTimingCode 2912; the CurrentTimingCode 1745 answer for that schedule names the goal,
 * which is asked with GetCommunityGoalHallOfFame 2167 -> CommunityGoalHallOfFame 3005.
 *
 * `goalCode` (the slot's own code, or the active community goal) skips the schedule. Only the answer
 * for the code asked is kept: the server also sends the legacy hall of fame with the news list.
