+### Fixed
+
+- Fixed a resource leak where `resp.Body` was deferred inside the results
+  pagination loop, preventing response bodies from being closed until the
+  entire `Results()` call returned. Extracted `fetchResultsPage()` helper.
+- Fixed empty results marshalling as `{"results": null}` instead of
+  `{"results": []}` when a completed job has zero results.
+- Eliminated a redundant `GetJobStatus` API call: `Results()` previously
+  fetched job status internally even though the caller had already done so.
+  The function now accepts `totalResults int` from the caller.
