Explanation:

* Duplicate identifies data quality issues where the same asset is modeled more than once, violating CMDB trust principles.
* Required ensures minimum viable CI creation and update-critical for ingestion and lifecycle integrity.
* Orphan highlights broken relationships, which directly impact impact analysis, Service Mapping, and Change Management.
* Stale flags CIs that are no longer being refreshed by Discovery or other sources but still exist in the CMDB.
* Recommended improves completeness and usability, supporting operational and reporting use cases without being mandatory.
* Audit validates data correctness by comparing CI field values against predefined templates or policies.
