## Why After app-server can accept `PermissionProfile`, first-party clients should stop preferring legacy sandbox fields when canonical permission information is available. This keeps the migration moving without removing legacy compatibility yet. The client side still has mixed surfaces during the stack: embedded thread start/resume/fork and exec initial turns can derive a profile directly from local config, while TUI remote sessions and some turn-start paths only have a legacy/server-context-safe sandbox projection. Those paths keep sending legacy sandbox fields rather than synthesizing or sending lossy/local-only profiles. ## What changed - Sends `permissionProfile` from exec and embedded TUI thread start/resume/fork requests when config has a representable profile. - Keeps legacy sandbox fallback for external sandbox policies, TUI remote thread lifecycle requests, and TUI turn-start requests that do not yet carry the active profile. - Sends the actual config-derived `permissionProfile` for exec initial turns instead of rebuilding one from the legacy sandbox projection. - Stores response `permissionProfile` as optional in TUI session state so external sandbox responses and compatibility payloads preserve `null`. - Updates tests for request construction and response mapping. ## Verification - `cargo check --tests -p codex-tui -p codex-exec` - `cargo test -p codex-tui app_server_session -- --nocapture` - `cargo test -p codex-exec thread_start_params -- --nocapture` - `cargo test -p codex-tui app_server_session::tests::thread_lifecycle_params -- --nocapture` - `just fix -p codex-tui -p codex-exec` - `just fix -p codex-tui` --- [//]: # (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.
