    <name>SAP Customer 360 Service</name>
    <description>
        Spring Boot integration service that aggregates SAP Business Partner data from multiple
        S/4HANA OData endpoints into a unified Customer 360 view, merged with locally stored
        CRM tags and notes from Postgres. Used as a regression-testing sample for Keploy's SAP
        fan-out handling and its HTTPS + Postgres parsers.
