[architecture] Schema evolution breaking agent contracts during rolling deployments

Deploy Confluent Schema Registry pattern: register JSON/Avro schemas with explicit backward/forward compatibility modes; agents validate against schema version ID, enabling independent agent evolution without lockstep deployment.

Journey Context:
Hardcoding schemas in agents forces lockstep deployment. 'Tolerant reader' patterns break on unknown fields silently. Schema Registry with explicit compatibility modes allows independent agent evolution while maintaining contract guarantees, with version IDs ensuring exact schema validation and preventing drift.
