## Why This is the next step in the Windows sandbox migration away from the legacy `SandboxPolicy` abstraction. #22923 moved write-root and token decisions onto `ResolvedWindowsSandboxPermissions`, but setup and identity still accepted `SandboxPolicy` and converted internally. This PR pushes that conversion outward so the setup path consumes the resolved Windows permission view directly. ## What Changed - Changed `SandboxSetupRequest` to carry `ResolvedWindowsSandboxPermissions` instead of `SandboxPolicy` plus policy cwd. - Updated setup refresh/elevation and identity credential preparation to use resolved permissions for read roots, write roots, network identity, and deny-write payload planning. - Removed the production `allow.rs` legacy wrapper; allow-path computation now takes resolved permissions directly. - Added a permissions-based world-writable audit entry point while keeping the existing legacy wrapper for compatibility. - Updated legacy ACL setup and the core Windows setup bridge to construct resolved permissions at the boundary. - Hardened the Windows sandbox integration test helper staging so Bazel retries can reuse an already-staged helper if a prior sandbox helper process still has the executable open. ## Verification - `cargo test -p codex-windows-sandbox` - `cargo test -p codex-core --test all --no-run` - `just fix -p codex-windows-sandbox` - `just fix -p codex-core` - Attempted `cargo check -p codex-windows-sandbox --target x86_64-pc-windows-gnullvm`, but the local machine is missing `x86_64-w64-mingw32-clang`; Windows CI should cover that target. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
