## Why The Linux sandbox helper still only accepted the legacy `SandboxPolicy` payload. That meant the runtime could compute split filesystem and network policies, but the helper would immediately collapse them back to the compatibility projection before applying seccomp or staging the bubblewrap inner command. ## What changed - added hidden `--file-system-sandbox-policy` and `--network-sandbox-policy` flags alongside the legacy `--sandbox-policy` flag so the helper can migrate incrementally - updated the core-side Landlock wrapper to pass the split policies explicitly when launching `codex-linux-sandbox` - added helper-side resolution logic that accepts either the legacy policy alone or a complete split-policy pair and normalizes that into one effective configuration - switched Linux helper network decisions to use `NetworkSandboxPolicy` directly - added `FromStr` support for the split policy types so the helper can parse them from CLI JSON ## Verification - added helper coverage in `linux-sandbox/src/linux_run_main_tests.rs` for split-policy flags and policy resolution - added CLI argument coverage in `core/src/landlock.rs` - verified the current PR state with `just clippy` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

npm i -g @openai/codex
or brew install --cask codex
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.
