## Overview

This appears to be a small Spring Kafka integration service: an HTTP-facing controller and producer/consumer services around Kafka. The tree identifies these roles, but no source excerpts or README relationships were provided, so links below are dashed and unverified. The event type and service contracts are shown as code components; their runtime interactions cannot be confirmed.
