## Why The Windows sandbox migration away from the legacy `SandboxPolicy` abstraction needs a small local bridge before IPC and core wiring can move to `PermissionProfile`. Leaf helpers currently branch directly on `WorkspaceWrite`, which spreads legacy assumptions through path planning and token setup code. This PR introduces a Windows-local resolved permissions view so those helpers can ask Windows-specific questions about runtime filesystem/network permissions without matching on the legacy policy enum everywhere. ## What changed - Added `ResolvedWindowsSandboxPermissions` in `windows-sandbox-rs/src/resolved_permissions.rs`, with legacy `SandboxPolicy` constructors for the current call sites. - Moved `allow.rs` writable-root and read-only-subpath planning onto the resolved permissions type. - Preserved Windows `TEMP`/`TMP` writable-root behavior when the effective policy includes writable tmpdir access. - Avoided resolving Unix `:slash_tmp` or parent-process `TMPDIR` while computing Windows writable roots. - Reused the shared allow-path result for setup write-root gathering and routed network-block selection through the resolved abstraction. ## Verification - `cargo test -p codex-windows-sandbox` - `just fix -p codex-windows-sandbox` - GitHub CI restarted on the amended commit; Windows Bazel is the required signal for the Windows-only code paths. --- [//]: # (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.
