## Why Persisting `WorldState` snapshots and patches is only useful if resume and fork restore that exact comparison baseline. Rebuilding it from `TurnContextItem` loses section state and can either repeat or suppress model-visible updates. This is the third PR in the WorldState persistence stack, built on #29835. ## What - Replay full WorldState snapshots and RFC 7386 patches through the existing rollout reconstruction segments. - Discard state from rolled-back turns and treat compaction as a baseline reset. - Hydrate `ContextManager` from the reconstructed snapshot on resume and fork. - Remove the synthetic `TurnContextItem` to WorldState conversion path. - Leave legacy or malformed rollouts without a baseline so the next update safely emits a full snapshot. ## Testing - `just test -p codex-core world_state` - `just test -p codex-core rollout_reconstruction_tests` - `just fix -p codex-core` - `just test -p codex-core` *(the changed tests passed; the full run also hit unrelated existing/test-environment failures, primarily a missing `test_stdio_server` binary)*
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
