+	     INFOPLIST_KEY_* only merges Xcode's recognised key list and it merges
+	     STRING values. BGTaskSchedulerPermittedIdentifiers must be an ARRAY, so
+	     the old INFOPLIST_KEY_BGTaskSchedulerPermittedIdentifiers build setting
+	     never produced a valid entry — App Store Connect rejected the upload
+	     with error 90771 as soon as UIBackgroundModes made the validator look.
+	     That build setting has been removed from project.pbxproj; do not put it
+	     back. Keep the identifier below in sync with the string passed to
+	     BGTaskScheduler.register/BGProcessingTaskRequest in JanitorialQCApp. -->
