The source moved between scouts and neither record cited the other. That record is SUMMARY-DERIVED; its claims are not re-verified here. Work the tree in **rounds**. The **frontier** is every decision whose prerequisites are already settled: the questions you can ask *now* without guessing at answers you have not heard yet.
