Where are the details of core and enhancing service provided?

The definitive media library stores authorized software versions and media assets, not service definitions or portfolio details.

The configuration management system stores data about configuration items and their relationships, not definitions of core and enhancing services.

The service portfolio contains the complete set of services managed by a service provider, spanning pipeline, active catalogue, and retired services. It documents both core services (primary IT functions) and enhancing or enabling services that support them. The service catalogue is only a customer-facing subset of the portfolio covering currently available services.

The service catalogue is a subset of the service portfolio listing only currently active services, so it does not contain the full scope of core and enhancing service details.
