## Stack fix: fail closed for unsupported split windows sandboxing #14172 -> fix: preserve split filesystem semantics in linux sandbox #14173 fix: align core approvals with split sandbox policies #14171 refactor: centralize filesystem permissions precedence #14174 ## Summary ## Summary - Preserve Linux split filesystem carveouts in bubblewrap by applying mount masks in the right order, so narrower rules still win under broader writable roots. - Preserve unreadable ancestors of writable roots by masking them first and then rebinding the narrower writable descendants. - Stop rejecting legacy-plus-split Linux configs that are sandbox-equivalent after `cwd` resolution by comparing semantics instead of raw legacy structs. - Fail closed when callers provide partial split policies, mismatched legacy-plus-split policies, or force `--use-legacy-landlock` for split-only shapes that legacy Landlock cannot enforce. - Add Linux regressions for overlapping writable, read-only, and denied paths, and document the supported split-policy enforcement path. ## Example Given a split filesystem policy like: ```toml [permissions.dev.filesystem] ":root" = "read" "/code" = "write" "/code/.git" = "read" "/code/secrets" = "none" "/code/secrets/tmp" = "write" ``` this PR makes Linux enforce the intended result under bubblewrap: - `/code` stays writable - `/code/.git` stays read-only - `/code/secrets` stays denied - `/code/secrets/tmp` can still be reopened as writable if explicitly allowed Before this, Linux could lose one of those carveouts depending on mount order or legacy-policy fallback. This PR keeps the split-policy semantics intact and rejects configurations that legacy Landlock cannot represent safely.

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.
