+// The pool is a LIVE DI singleton, so a tester may already have real pop-outs open
+// when /xlperf runs; the step tests against the FREE slots (not full capacity) and
+// only ever closes ids it opened, so it neither false-REDs on a non-empty pool nor
+// disturbs real pop-outs. The pure slot-map math is pinned by PopoutSlotMapTests
+// (Build-Suite); this step proves the live wiring on top of it. Every slot reserved
+// is released before RunStep returns, so no pop-out is left bound.
