Imported (reference) auth resources have no nested CloudFormation stack — they reference externally-managed Cognito resources. The refactor step was unconditionally creating an AuthCognitoForwardRefactorer for every auth:Cognito resource, which then failed with "unable to find source stack" because there is no stack to find. Now checks serviceType === 'imported' in amplify-meta.json before creating the refactorer, matching the existing pattern in the generate step. Added tests for both forward and rollback paths. --- Prompt: In the gen2-migration tool, I am getting this error when trying to refactor an app with an imported auth resource - "[AuthCognitoForwardRefactorer] unable to find source stack"

When you run
amplify gen2-migration refactoron an app with an imported auth resource, the refactor step was crashing with "unable to find source stack." That's because imported auth resources are just references to externally-managed Cognito resources — they don't have a nested CloudFormation stack in the Gen1 root stack. Therefactorwas trying to find one and failing.The generate step already handled this correctly — it checks serviceType === 'imported' in amplify-meta.json and uses a ReferenceAuthGenerator instead of the normal AuthGenerator. The refactor step had no such check.
The fix adds the same check to refactor.ts in both forward() and rollback(). When the auth resource is imported, we skip creating the AuthCognitoForwardRefactorer / AuthCognitoRollbackRefactorer entirely — there's nothing to move.
