+Permissions are:

+- compose

+  - NOTE: Unlike most operating systems, this permission does _not_ grant the
+    ability to create new nodes or write to nodes not created by the current app.
+    See `overwrite` below for that.
+- overread
+  - This grants the ability to query for nodes outside of ones created by the
+    current app.
+- overwrite
+  - This grants the ability to write into nodes outside of ones created by the
