[Test] (P11 M2): dev's two Magma scenarios on the split arms - both on Espryt's three arms, OversizedRecordingSplitScenario on Magma's three (and pinned to a 64-draw budget on split and spawn, where the server reads it), DescriptorPoolGrowthScenario's census cases on Magma's split arm only; the split-recording arming reads both role logs and dev's pinned lane holds its log's RESOURCE_LOCK, and the census cases count the sets the wire arm holds between its descriptor rewinds
