+      NODE-BOUND LEG (emmett#44, cluster#192): aarch64-linux can't be built on
+      emmett (linux/amd64) and these native packages have no cross path, so this
+      leg must run on an aarch64 node (the arch nodeSelector above). Same
+      parity-lib attic-closure front door as amd64, only the arch app differs.
