## Why Guardian analytics includes time-to-first-token, but the Guardian reviewer runs as a normal Codex session and `TurnCompleteEvent` did not expose TTFT. The timing needs to flow through the standard turn-completion protocol so Guardian review analytics can consume the same value as the rest of the session machinery. ## What changed Adds optional `time_to_first_token_ms` to `TurnCompleteEvent` and populates it from `TurnTiming`. The value is carried through app-server thread history, rollout reconstruction, TUI/app-server adapters, and Guardian review session handling. Guardian review analytics now captures TTFT from the reviewer turn-complete event when available. Existing tests and fixtures are updated to set the new optional field to `None` where TTFT is not relevant. ## Verification - `cargo clippy -p codex-tui --tests -- -D warnings` - `cargo clippy -p codex-core --lib --tests -- -D warnings` --- [//]: # (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.
