Start with the foundry-api.switchDefaultProject action and the F.createCognitiveServiceAccount and newProjectWithAccount entries shown in extension.js. Reproduce the HTTP 409 for the Microsoft.CognitiveServices registration error and determine the expected behavior when the subscription is not registered; done means the failure path is confirmed and its handling is covered by the project's available tests.
