TL;DR

The issue can be mitigated by modifying the Codex Desktop application to preserve the last visible assistant closeout bubble in the original thread when the Stop button is pressed.

Guidance

• Investigate the Codex Desktop code responsible for handling the Stop button press and checkpoint creation to identify why the last visible assistant closeout bubble is removed from the original thread.
• Verify that the continuation thread is correctly created and contains the expected auto-checkpoint for the same session.
• Review the application's thread management and UI update logic to ensure that the original thread's state is properly preserved when the Stop button is pressed.
• Consider adding logging or debugging statements to track the state of the original thread and the continuation thread when the Stop button is pressed.

Example

No code snippet can be provided without more information about the Codex Desktop application's internal implementation.

Notes

The issue may be related to the application's handling of thread state and UI updates when the Stop button is pressed. Further investigation is needed to determine the root cause of the problem.

Recommendation

Apply a workaround to preserve the last visible assistant closeout bubble in the original thread when the Stop button is pressed, such as modifying the application's thread management and UI update logic. This is recommended because the issue is specific to the Codex Desktop application and a workaround can be implemented without affecting other parts of the system.
