## Why `SandboxPolicy` currently mixes together three separate concerns: - parsing layered config from `config.toml` - representing filesystem sandbox state - carrying basic network policy alongside filesystem choices That makes the existing config awkward to extend and blocks the new TOML proposal where `[permissions]` becomes a table of named permission profiles selected by `default_permissions`. (The idea is that if `default_permissions` is not specified, we assume the user is opting into the "traditional" way to configure the sandbox.) This PR adds the config-side plumbing for those profiles while still projecting back to the legacy `SandboxPolicy` shape that the current macOS and Linux sandbox backends consume. It also tightens the filesystem profile model so scoped entries only exist for `:project_roots`, and so nested keys must stay within a project root instead of using `.` or `..` traversal. This drops support for the short-lived `[permissions.network]` in `config.toml` because now that would be interpreted as a profile named `network` within `[permissions]`. ## What Changed - added `PermissionsToml`, `PermissionProfileToml`, `FilesystemPermissionsToml`, and `FilesystemPermissionToml` so config can parse named profiles under `[permissions.<profile>.filesystem]` - added top-level `default_permissions` selection, validation for missing or unknown profiles, and compilation from a named profile into split `FileSystemSandboxPolicy` and `NetworkSandboxPolicy` values - taught config loading to choose between the legacy `sandbox_mode` path and the profile-based path without breaking legacy users - introduced `codex-protocol::permissions` for the split filesystem and network sandbox types, and stored those alongside the legacy projected `sandbox_policy` in runtime `Permissions` - modeled `FileSystemSpecialPath` so only `ProjectRoots` can carry a nested `subpath`, matching the intended config syntax instead of allowing invalid states for other special paths - restricted scoped filesystem maps to `:project_roots`, with validation that nested entries are non-empty descendant paths and cannot use `.` or `..` to escape the project root - kept existing runtime consumers working by projecting `FileSystemSandboxPolicy` back into `SandboxPolicy`, with an explicit error for profiles that request writes outside the workspace root - loaded proxy settings from top-level `[network]` - regenerated `core/config.schema.json` ## Verification - added config coverage for profile deserialization, `default_permissions` selection, top-level `[network]` loading, network enablement, rejection of writes outside the workspace root, rejection of nested entries for non-`:project_roots` special paths, and rejection of parent-directory traversal in `:project_roots` maps - added protocol coverage for the legacy bridge rejecting non-workspace writes ## Docs - update the Codex config docs on developers.openai.com/codex to document named `[permissions.<profile>]` entries, `default_permissions`, scoped `:project_roots` syntax, the descendant-path restriction for nested `:project_roots` entries, and top-level `[network]` proxy configuration --- [//]: # (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.
