What issue are you seeing?

Codex App thread disappeared. Session was not listed in codex on the host accessed over SSH either.

Cause: JSON for history was broken, did not validate. Works after removing offending and broken parts of the JSON.

RCA: Codex had issues with encoding JSON files, may write broken JSON it can read. Trips over on its own files.
