- LoginComponent: provide ActivatedRoute stub (component reads returnUrl query param) - UploadComponent: add cdr.markForCheck() to handleUploadError so OnPush view updates when the method is called directly; fix success test to check showSuccess not toastMessage - DetailComponent: drive not-found-card and tag-error tests through component methods that call markForCheck() rather than directly mutating state on OnPush components Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
