## Why `WorldState` currently remembers its model-visible diff baseline only in memory. That leaves no durable source for restoring the exact baseline after resume, fork, rollback, or compaction. This is the second PR in the WorldState persistence stack, built on #29833 and following #29249. It records durable state transitions; the next PR will replay them during rollout reconstruction. ## What - Add a `world_state` rollout item containing either a full snapshot or an RFC 7386 JSON Merge Patch. - Persist a full snapshot after initial context and after compaction establishes a new context window. - Persist non-empty patches when later sampling steps or turns advance the WorldState baseline. - Write model-visible history before its matching WorldState record, so an interrupted write can only cause a safe repeated update on replay. - Preserve WorldState records for full-history forks while excluding them from thread previews, metadata, and app-server history materialization. Older binaries read rollout lines independently, so they skip the unknown `world_state` records while retaining the rest of the thread. ## Testing - `just test -p codex-core snapshot_merge_patch_changes_and_removes_nested_values` - `just test -p codex-core world_state_baseline_deduplicates_until_history_is_replaced` - `just test -p codex-core deferred_executor_compaction_preserves_then_updates_environment_once` - `just test -p codex-protocol` - `just test -p codex-rollout` - `just test -p codex-state` - `just test -p codex-thread-store` - `just test -p codex-app-server-protocol`

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.
