What issue are you seeing?

Codex intermittently fails during automatic context compaction with this error:

Error running remote compact task: stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses/compact)

It seems the remote compact request is interrupted before completion.

What steps can reproduce the bug?

1. Open Codex App.
2. Work in a long session until automatic context compaction is triggered.
3. When Codex starts the remote compact task, it sometimes fails with:

Error running remote compact task: stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses/compact)

The issue is intermittent and may require a long session to reproduce.

What is the expected behavior?
