SERVICE

The service a request to the internal port comes from, by name: every node states its own, spring.application.name, on its forwards, wait signals, synchronous calls and peer reads. It is a statement, not a credential: the internal port is reachable by the platform's own pods alone (a NetworkPolicy), and the name serves to catch a misconfiguration, such as a call a service does not list or a forward to another service's node. The public port never reads it.
