## Summary Translate FileSystemSandboxPolicy project root metadata carveouts into macOS Seatbelt rules. ## Scope 1. Thread protected metadata names into Seatbelt access roots. 2. Ask FileSystemSandboxPolicy whether each metadata carveout is writable. 3. Emit Seatbelt deny rules that block creating or replacing protected metadata names under writable roots. 4. Add coverage for first time metadata creation and read only carveouts. ## Reviewer Focus 1. This PR only covers the macOS sandbox adapter. 2. The policy decision comes from FileSystemSandboxPolicy. 3. Read only subpath carveouts and metadata protection checks should compose cleanly. ## Stack 1. Policy primitive: #19846 2. macOS Seatbelt adapter: this PR 3. Shell preflight UX: #19848 4. Runtime profile propagation: #19849 5. Linux bubblewrap adapter: #19852 ## Validation 1. formatting for codex sandboxing 2. codex sandboxing package tests

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.
