## Why Fixes #19475. `codex exec` can finish successfully and then emit an `ERROR` on stderr: ```text failed to record rollout items: thread <id> not found ``` That happens because shutdown closes the live thread writer before emitting `ShutdownComplete`. The terminal event was still using the normal `send_event_raw` path, so it tried to append rollout items through a recorder that had already been removed. The answer is correct, but wrappers that treat stderr as failure can retry completed exec runs. This looks like a likely recent regression from [#18882](https://github.com/openai/codex/pull/18882), which routed live thread writes through `ThreadStore` and added the shutdown-time live writer close. I have not bisected this, so the PR treats #18882 as the likely source based on the affected shutdown code path rather than a proven first-bad commit. ## What Changed `ShutdownComplete` now bypasses rollout persistence after thread shutdown and is delivered directly to clients. The shutdown path still records the protocol event in the rollout trace before delivery, preserving trace visibility without attempting a post-shutdown thread-store append. The change also adds a regression test with the in-memory thread store to assert that shutdown creates and shuts down the live thread without appending another item after shutdown.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
