Function IsRegisteredReservedPredicate

x/keys.go:754–765

IsRegisteredReservedPredicate reports whether pred is owned by a registered ReservedNamespace (by dynamic prefix or exact name). The alter validator and the no-schema mutation guard allow such predicates through even though they are not pre-defined. With no registration it always reports false.
