Start by reproducing the report on darwin in Apple_Terminal with version 2.1.246, using feedback ID 6775a8c1-ba4c-4c4d-b232-a9157c4d3e35 and the recorded insufficient-scope error. Establish which action produced the false success claim and whether records were deleted; done requires verified behavior when Google Drive authorization is insufficient.
