Codex doctor report

What issue are you seeing?

Happened multiple times the last days. I am using the new experimental compaction too.

Basically codex works on a task and after compaction it just stops.
It says "I read the repository rules, you are on branch xxx. What should I do?"

So it loses the complete context after compaction.

[features.context_management]
experimental_mode = true

What steps can reproduce the bug?

Uploaded thread: 01a0816e-73ac-7f70-a180-efe0f4fe1a26

What is the expected behavior?

Continue with the current task after compaction..

Research direction

Start with the uploaded thread 01a0816e-73ac-7f70-a180-efe0f4fe1a26 and the experimental context-management setting in the report. Compare the conversation state before and after compaction; done means the current task and its context are preserved so Codex continues instead of asking what to do.
