Agent IDE — Codex fork for AI-native development environment

## Why After `#13449`, the Linux helper could receive split filesystem and network policies, but the bubblewrap mount builder still reconstructed filesystem access from the legacy `SandboxPolicy`. That loses explicit unreadable carveouts under writable roots, and it also mishandles `Root` read access paired with explicit deny carveouts. In those cases bubblewrap could still expose paths that the split filesystem policy intentionally blocked. ## What changed - switched bubblewrap mount generation to consume `FileSystemSandboxPolicy` directly at the implementation boundary; legacy `SandboxPolicy` configs still flow through the existing `FileSystemSandboxPolicy::from(&sandbox_policy)` bridge before reaching bwrap - kept the Linux helper and preflight path on the split filesystem policy all the way into bwrap - re-applied explicit unreadable carveouts after readable and writable mounts so blocked subpaths still win under bubblewrap - masked denied directories with `--tmpfs` plus `--remount-ro` and denied files with `--ro-bind-data`, preserving the backing fd until exec - added comments in the unreadable-root masking block to explain why the mount order and directory/file split are intentional - updated Linux helper call sites and tests for the split-policy bwrap path ## Verification - added protocol coverage for root carveouts staying scoped - added core coverage that root-write plus deny carveouts still requires a platform sandbox - added bwrap unit coverage for reapplying blocked carveouts after writable binds - added Linux integration coverage for explicit split-policy carveouts under bubblewrap - validated the final branch state with `cargo test -p codex-linux-sandbox`, `cargo clippy -p codex-linux-sandbox --all-targets -- -D warnings`, and the PR CI reruns --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
