Summary

After the standalone Codex desktop application was replaced by the new unified ChatGPT desktop application, my existing repositories can be reattached successfully, but all historical Codex project threads appear to be missing.

---

What happened

1. Windows installed normal updates and restarted.
2. The standalone Codex desktop application was replaced by the new ChatGPT desktop application.
3. I was prompted to sign in again.
4. Initially the Projects section showed "No projects."
5. My ChatGPT cloud Projects and conversations remained available on chatgpt.com.
6. I reattached my existing Git repositories using:

Projects → Use an existing folder

Both repositories were detected correctly.

Examples:

C:\Bespoke\bespoke-operating-system

C:\Bespoke\bespoke-automation-governance

The application correctly recognizes:

• Git repository
• Branch (main)
• Local repository path

However each repository reports:

0 threads

Searching for previous work only returns ChatGPT conversations and does not return any historical Codex project threads.

---

Expected behavior

If historical Codex project threads are intended to migrate to the unified ChatGPT desktop application, they should remain associated with the repository after reattachment.

If migration is not currently supported, it would be helpful for the application to communicate that existing Codex project thread history will not be available after migration.

---

What is still working

• ChatGPT cloud Projects are intact.
• ChatGPT conversations are searchable.
• Git repositories are intact.
• Git history is intact.
• Repository contents are intact.
• Existing repositories can be attached successfully.

Only the historical Codex project thread history appears to be missing.

---

Additional notes

Windows setup completed successfully after attaching the repositories.

The issue persists after:

• signing out and back in
• reattaching repositories
• completing Windows setup

What steps can reproduce the bug?

1. Use the standalone Codex desktop application with one or more existing Git repository projects containing historical Codex threads.

1. Update to the new unified ChatGPT desktop application (Powered by Codex & OWL).

1. Restart Windows if prompted.

1. Launch the new ChatGPT desktop application.

1. Sign in again if prompted.

1. Observe that the Projects section reports "No projects."

1. Reattach the existing repository using:

Projects → Use an existing folder

1. Select the existing Git repository.

1. Observe that:

• The repository is detected correctly.
• The Git branch is detected correctly.
• The repository opens successfully.
• The project reports "0 threads."
• Searching only returns ChatGPT conversations and does not return historical Codex project threads.

What is the expected behavior?
