+// "Export my data": every installed module's share of the account, composed into one document.
+//
+// Each module that keeps something about the person contributes an export to kit-tenancy's
+// `tenancy.account` point -- this module's own rows among them -- and every one of them is a section.
+// A module that fails is a `failed` section and the export is `complete: false`, naming it; a module
+// that can erase but not export is `not_exported`. Nothing is left out without saying so (joint
+// contract §12).
