# Requirement change

Ops wants to run a "best agent of the month" shout-out in the team standup, and right now the only
number we can give them is an agent's average across their whole career, which isn't what they're
asking for — they want to know who did best in a specific month.

So: given a month, tell me the agents who were rated that month, ranked the same way the main
leaderboard is ranked — highest average for that month first, and if two people tie for that month,
break it exactly the way a tie is already broken today. Whoever comes out on top of that list is
the answer to "who had the best month" — we're not asking for anything new about how a tie works,
just the same rule applied to one month's ratings instead of all of them.

An agent who received no ratings at all in that month should not show up in that month's list, even
if they've been rated plenty in other months. And a month with nobody rated in it at all is a
legitimate, empty answer — not an error.

Everything else is unchanged: the scale, the all-time leaderboard, both exports, and the refusal for
an agent nobody has ever rated.
