+The settings page asks the node on this machine again before deciding there is
+none.
+
+`readLocalNode` (group-settings.js) is lifted out and run under node against a
+stub of `platform.node`. One missed 3 s check used to set "no node here", which
+hides "Add a directory", until the page was reloaded: found by a tester adding a
+directory while the node was busy indexing the others.
