### Other Details

_No response_

Start with the linked boto3 create_assessment_framework and update_assessment_framework documentation to verify the requested Framework properties and operations. The issue names no repository files or tests; clarify the Assessment/Framework naming mismatch and identify the implementation and coverage-test locations. Done should include native AWS::AuditManager::Framework support and a Ref value returning the framework ID.
