Cua Sandbox 0.9.1 rejects the retired cloud target

Cua’s migration guide dates the end of Cua Cloud and Fleets to 18 October. Sandbox 0.9.1 now stops on="cloud" calls with an explicit error. Local execution and your own AWS, Google Cloud or Modal account remain alternatives. Review placement, pool references and lifecycle scripts before the next run; changing the package pin cannot restore a retired service. ²³
