## Why `#13434` and `#13439` introduce split filesystem and network policies, but the only code that could answer basic filesystem questions like "is access effectively unrestricted?" or "which roots are readable and writable for this cwd?" still lived on the legacy `SandboxPolicy` path. That would force later backends to either keep projecting through `SandboxPolicy` or duplicate path-resolution logic. This PR moves those queries onto `FileSystemSandboxPolicy` itself so later runtime and platform changes can consume the split policy directly. ## What changed - added `FileSystemSandboxPolicy` helpers for full-read/full-write checks, platform-default reads, readable roots, writable roots, and explicit unreadable roots resolved against a cwd - added a shared helper for the default read-only carveouts under writable roots so the legacy and split-policy paths stay aligned - added protocol coverage for full-access detection and derived readable, writable, and unreadable roots ## Verification - added protocol coverage in `protocol/src/protocol.rs` and `protocol/src/permissions.rs` for full-root access and derived filesystem roots - 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.
