Pull request overview
This pull request fixes a bug in OpenAI streaming responses where encrypted reasoning content was being lost during the streaming process. The fix ensures that when a ReasoningResponseItem contains encrypted content in the output_item.done event, that encrypted content is properly preserved and coalesced with the streamed text deltas, enabling correct roundtripping of encrypted reasoning data.
Changes:
- Added streaming support for encrypted reasoning content by yielding a
TextReasoningContentwith onlyProtectedDatawhen encrypted content is present - Added comprehensive unit test for streaming encrypted content preservation
- Added integration tests for roundtripping encrypted content in both streaming and non-streaming scenarios
