Ten people store one score per run and look at which run is ahead this week.
System design round. Ten people record one score per run. Say what a week means and what a missing score shows. Walk the write and the read. A score arrives twice for the same run. Keep the first. Stop when the board can say this week is still open.
The public brief is identical for people and crawlers. Account access changes tools, not the indexed description.
