## Why This bug is exposed by Guardian/auto-review approvals. With the managed network proxy enabled, a blocked network request can be reported back through the network approval service as an approval denial after the command has already started. Before this change, the shell and unified exec runtimes registered those network approval calls, but did not have a way to observe an async proxy denial as a cancellation/failure signal for the running process. The result was confusing: Guardian/auto-review could correctly deny network access, but the command path could keep running or unregister the approval without surfacing the denial as the command failure. ## What Changed - `NetworkApprovalService` now attaches a cancellation token to active and deferred network approvals. - Proxy-denial outcomes are recorded only for active registrations, cancel the owning token, and are consumed when the approval is finalized. - The shell runtime combines the normal command timeout with the network-denial cancellation token. - Unified exec stores the deferred network approval object, terminates tracked processes when the proxy denial arrives, and returns the denial as a process failure while polling or completing the process. - Tool orchestration passes the active network approval cancellation token into the sandbox attempt and preserves deferred approval errors instead of silently unregistering them. - App-server `command/exec` now handles the combined timeout-or-cancellation expiration variant used by the runtime. ## Verification - `cargo test -p codex-core network_approval --lib` - `cargo clippy -p codex-app-server --all-targets -- -D warnings` - `cargo clippy -p codex-core --all-targets -- -D warnings` --------- Co-authored-by: Codex <noreply@openai.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.
