+A rider belongs to a shop or to a delivery partner — never to neither, never to
+both.
+
+`CreateRider` used to demand a tenantid outright, which made a partner's rider
+impossible to create: a partner supplies riders to many merchants and their
+riders sit under no single one. The two ids are now exclusive, and both mistakes
+are refused rather than one being silently preferred — a rider carrying both
+appears in two directories and two assign pickers, with nothing downstream
+saying which owns them.
+
+`riderOwner` is the rule on its own so it can be checked without a request.
