## Why After thread sessions have a required `PermissionProfile`, the TUI no longer needs to cache a separate legacy `SandboxPolicy` in `ThreadSessionState`. Keeping the legacy field would reintroduce two permission authorities in the session cache and make later replay/switching logic easier to get wrong. This PR keeps legacy app-server compatibility at the ingestion boundary: old `sandbox` response values are still accepted, but they are immediately converted to a cwd-anchored profile. ## What Changed - Removes `ThreadSessionState.sandbox_policy`. - Updates active-session permission syncing to write only the current `PermissionProfile`. - Updates thread-read/replay/test fixtures to use profiles as the cached session permission source. - Leaves legacy `sandbox` fields in app-server request/response protocol paths unchanged; those are compatibility boundaries and are converted before entering cached TUI state. ## Verification - `cargo test -p codex-tui thread_session_state::tests --lib` - `cargo test -p codex-tui inactive_thread_started_notification_initializes_replay_session --lib` - `cargo test -p codex-tui thread_events --lib` - `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.
