The CRD validation schema defines broker, nameService, and console as type: object with no sub-properties. This provides zero validation for nested fields, meaning any malformed spec will be accepted by the API server. At minimum, required sub-fields should be enumerated, or the full nested schemas from the Broker/NameService/Console CRDs should be inlined.

The selector name_service_cr: ${rocketmq-name}-name-service uses a shell variable placeholder ${rocketmq-name} that is not substituted by kubectl. Users must manually replace this value, but this is not documented and will silently result in a Service with no matching pods if applied as-is.
