LICENSE-attested or repo-attested upstream is now called out at the

ZAP (luxfi/zap) listener on port 9222 for binary RPC control plane
operations (create/delete/list streams, publish, health check).
HTTP management API on port 9280 wrapping NATS monitoring endpoints
and JetStream stream info. NATS client protocol on 4222 unchanged.
