The minimal Microsoft Graph calendar surface GraphCalendarSource drives. A production wiring implements this over
@microsoft/microsoft-graph-client—GET /users/{userId}/calendarView/delta(or/me/events/delta), following@odata.nextLinkpage-to-page and capturing the final@odata.deltaLink. Tests inject a fake. NO Graph SDK types leak through this surface.
