## Why #18274 made `PermissionProfile` the canonical file-system permissions shape, but the round-trip from `FileSystemSandboxPolicy` to `PermissionProfile` still dropped one piece of policy metadata: `glob_scan_max_depth`. That field is security-relevant for deny-read globs such as `**/*.env`. On Linux, bubblewrap sandbox construction uses it to bound unreadable glob expansion. If a profile copied from active runtime permissions loses this value and is submitted back as an override, the resulting `FileSystemSandboxPolicy` can behave differently even though the visible permission entries look equivalent. ## What changed - Add `glob_scan_max_depth` to protocol `FileSystemPermissions` and preserve it when converting to/from `FileSystemSandboxPolicy`. - Keep legacy `read`/`write` JSON for simple path-only permissions, but force canonical JSON when glob scan depth is present so the metadata is not silently dropped. - Carry `globScanMaxDepth` through app-server `AdditionalFileSystemPermissions`, generated JSON/TypeScript schemas, and app-server/TUI conversion call sites. - Preserve the metadata through sandboxing permission normalization, merging, and intersection. - Carry the merged scan depth into the effective `FileSystemSandboxPolicy` used for command execution, so bounded deny-read globs reach Linux bubblewrap materialization. ## Verification - `cargo test -p codex-sandboxing glob_scan -- --nocapture` - `cargo test -p codex-sandboxing policy_transforms -- --nocapture` - `just fix -p codex-sandboxing` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
