Research direction

Start with openstack-seeder/pkg/seeder/apis/v1/types.go around lines 624-680 and inspect the MergeStructFields call in the project merge loop. Trace how the referenced value is used and determine whether the analyzer finding changes behavior. Done means classifying the finding as a bug, mitigated, or desirable behavior, with supporting evidence.
