## Why This is the third PR in the Windows sandbox `SandboxPolicy` -> `PermissionProfile` migration stack. #22896 introduced `ResolvedWindowsSandboxPermissions`, and #22918 moved elevated runner IPC to carry `PermissionProfile`. This PR starts moving the remaining setup/spawn helpers away from asking legacy enum questions like “is this `WorkspaceWrite`?” and toward resolved runtime permission questions like “does this profile require write capability roots?” ## What changed - Added resolved-permissions helpers for network identity and write-capability detection. - Moved setup write-root gathering to operate on `ResolvedWindowsSandboxPermissions`, with the legacy `SandboxPolicy` wrapper left in place for existing call sites. - Updated identity setup, elevated capture setup, and world-writable audit denies to use resolved write roots. - Updated spawn preparation to carry resolved permissions in `SpawnContext` and use them for network blocking, setup write roots, elevated capability SID selection, and legacy capability roots. - Removed a now-unused legacy write-root helper. ## Verification - `cargo test -p codex-windows-sandbox` - `just fix -p codex-windows-sandbox` - Existing stack checks are green on #22896 and #22918; CI has started for this PR. --- [//]: # (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.
