record_replica_metadata

async PDPrefillServer.record_replica_metadata() → Dict[str, Any]

Publish this prefill replica’s connector coordination metadata.

Read by the decode orchestrator via the replica-metadata hook (ReplicaSelection.replica_metadata) so peer-binding connectors (e.g. MoRIIO) can address the selected prefill replica. Returns {} for connectors that publish nothing (the BaseConnectorBackend default).

Returns the metadata of the backend that engine init (setup_engine_backend) created, setup()-ed, and stored on this server’s _llm_config. The replica-metadata hook is captured after engine init, so for connector deployments the backend is present by then; with no backend stored there is nothing to publish.
