What issue are you seeing?

In most threads, my conversations hit an error with a message like:

'Item 'msg_083fb2d2a8606450006a561f65e53c81a4ac2a6903b39cfa05' of type 'message' was provided without its required 'reasoning' item: 'rs_083fb2d2a8606450006a561f629aac81a48c129f085ecd82c7'.'

Codex's understanding is:

In session 019f605f-0fdd-7b43-8a42-399a93460ff8 (Codex 0.144.2), the failing commentary message was persisted at 11:26:47.354Z; its required reasoning item arrived later at 11:26:49.829Z. Every other assistant update in that session has its reasoning item immediately before it. So when Codex reconstructed the next request, it sent the message before its dependency and the API rejected it.
This looks like a race around mid-rollout/commentary updates during tool-heavy work. The required rs_… record is present in the local transcript—it’s just in the wrong order—so the task cannot reliably recover by retrying, compacting, or editing the repo.

This is happening in most threads, after maybe 5-10 messages...
