## Why `SessionConfiguredEvent` is the internal event that tells clients what permissions are active for a session. Emitting both `sandbox_policy` and `permission_profile` leaves two possible authorities and forces every consumer to decide which one to honor. At this point in the migration, the profile is expressive enough to represent managed, disabled, and external sandbox enforcement, so the internal event can be profile-only. The wire compatibility concern is older serialized events or rollout data that only contain `sandbox_policy`; those still need to deserialize. ## What Changed - Removes `sandbox_policy` from `SessionConfiguredEvent` and makes `permission_profile` required. - Adds custom deserialization so old payloads with only `sandbox_policy` are upgraded to a cwd-anchored `PermissionProfile`. - Updates core event emission and TUI session handling to sync permissions from the profile directly. - Updates app-server response construction to derive the legacy `sandbox` response field from the active thread snapshot instead of from `SessionConfiguredEvent`. - Updates yolo-mode display logic to treat both `PermissionProfile::Disabled` and managed unrestricted filesystem plus enabled network as full-access, while still preserving the distinction between no sandbox and external sandboxing. ## Verification - `cargo test -p codex-protocol session_configured_event --lib` - `cargo test -p codex-protocol serialize_event --lib` - `cargo test -p codex-exec session_configured --lib` - `cargo test -p codex-app-server thread_response_permission_profile_preserves_enforcement --lib` - `cargo test -p codex-core session_configured_reports_permission_profile_for_external_sandbox --lib` - `cargo test -p codex-tui session_configured --lib` - `cargo test -p codex-tui yolo_mode_includes_managed_full_access_profiles --lib` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.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.
