Start by reading pkg/registry/rbac/rest/storage_rbac.go at lines 276-303 and inspect how the range variable is referenced in the reconciliation options. Verify whether the analyzer finding affects runtime behavior, then check the surrounding Kubernetes RBAC reconciliation flow and relevant tests before classifying it as a bug, mitigated, or desirable behavior.
