## Summary - add elevated-only token constructors that include the current token user SID in the restricted SID list - switch the elevated Windows command runner to use those constructors - leave the unelevated restricted-token path unchanged ## Why Windows named pipes created by tools like Ninja use the platform's default named-pipe ACL when no explicit security descriptor is provided. In the elevated sandbox, the pipe owner has access, but the write-restricted token can still fail its restricted-SID access check because the sandbox user SID was not in the restricting SID set. That causes child processes to exit successfully while Ninja never receives the expected pipe completion/close behavior and hangs. Including the elevated sandbox user's SID in the restricting SID list lets the restricted check succeed for these owner-scoped pipe objects without broadening the unelevated sandbox to the real signed-in user. ## Impact - fixes the minimal Ninja hang repro in the elevated Windows sandbox - preserves the existing unelevated sandbox behavior and write protections - keeps the change scoped to the elevated runner rather than changing shared token semantics - this does not affect file-writes for the sandbox because the sandbox users themselves do not receive any additional permissions over what the capability SIDs already have. In fact we don't even explicitly grant the sandbox user ACLs anywhere. ## Validation - `cargo build -p codex-windows-sandbox --quiet` - verified the stock `ninja.exe` minimal repro exits normally on host and in the elevated sandbox - verified the same repro still hangs in the unelevated sandbox, which is the intended scope of this change

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.
