## Why `ThreadSessionState` is the TUI's cached view of an app-server session. To make `PermissionProfile` the canonical runtime permissions model, cached thread sessions need to always have a profile instead of treating the profile as an optional supplement to a legacy `sandbox` response field. The main compatibility concern is older app-server v2 lifecycle responses that only include `sandbox` and omit `permissionProfile`: - `thread/start` -> `ThreadStartResponse.sandbox` - `thread/resume` -> `ThreadResumeResponse.sandbox` - `thread/fork` -> `ThreadForkResponse.sandbox` Those responses must still hydrate correctly when the TUI is pointed at an older app-server. This PR converts the legacy `sandbox` value into a `PermissionProfile` immediately at response ingestion time, using the response `cwd`, so cached sessions do not carry an optional profile that can later reinterpret cwd-bound grants against a different thread cwd. This fallback is intentionally boundary compatibility. The follow-up PRs in this stack continue the cleanup by making `SessionConfiguredEvent` profile-only, deriving sandbox projections from snapshots only when an API still needs them, and then removing `sandbox_policy` from `ThreadSessionState`. ## What Changed - Makes `ThreadSessionState.permission_profile` required. - Converts legacy app-server response `sandbox` values into a `PermissionProfile` at ingestion time using the response cwd. - Ensures `thread/read` hydration does not reuse a primary session profile that may be anchored to a different cwd; it uses the active widget permission settings for the read thread fallback instead of reusing cached primary-session permissions. - Keeps the app-server request path unchanged: embedded sessions send profiles, while remote sessions continue using legacy sandbox overrides for compatibility. ## Verification - `cargo test -p codex-tui thread_read --lib` - `cargo test -p codex-tui permission_settings_sync_preserves_active_profile_only_rules --lib` - `cargo test -p codex-tui resume_response_restores_turns_from_thread_items --lib` - `cargo test -p codex-tui thread_session_state::tests --lib` --- [//]: # (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.
