+summary: >
+  Code-quality refactor in omnibase_infra: extracted _ProtocolDispatchPort Protocol from
+  service_delegation_dispatch_port.py to satisfy the mixed-types validator, renamed it to
+  ProtocolDelegationDispatchPort, applied lint formatting fixes, and stamped the schema
+  fingerprint. No runtime paths changed; this is a pure structural cleanup.
