## Why A restricted filesystem policy that grants `:root` read or write access but also carries explicit deny entries should still behave like scoped access with carveouts, not like unrestricted disk access. Without that distinction, later platform backends cannot preserve blocked subpaths under root-level permissions because the protocol layer reports the policy as fully unrestricted. ## What changed - taught `FileSystemSandboxPolicy` to treat root access plus explicit deny entries as scoped access rather than full-disk access - derived readable and writable roots from the filesystem root when root access is combined with carveouts, while preserving the denied paths as read-only subpaths - added protocol coverage for root-write policies with carveouts and a core sandboxing regression so those policies still require platform sandboxing ## Verification - added protocol coverage in `protocol/src/permissions.rs` and `protocol/src/protocol.rs` for root access with explicit carveouts - added platform-sandbox regression coverage in `core/src/sandboxing/mod.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.
