## Why Several analytics event families need the same per-thread attribution state: the app-server client/runtime associated with a thread and, for lifecycle-oriented events, the thread metadata captured during initialization. Keeping connection ids and lifecycle metadata in separate maps made each consumer rebuild the same thread context and made subagent attribution harder to resolve consistently. ## What changed - Replaces the separate thread connection and metadata maps with one reducer-owned `threads` map. - Routes guardian, compaction, turn-steer, and turn analytics through shared thread-state lookups while preserving turn-origin attribution for turn events and request-origin attribution for steer events. - Lets newly observed spawned subagent threads inherit their parent thread connection so later thread-scoped analytics can resolve through the same state model. - Adds regression coverage for standalone `SubAgentThreadStarted` publication plus the `SubAgentSource::ThreadSpawn` parent fallback through a thread-scoped consumer that depends on inherited connection state. ## Verification - `cargo test -p codex-analytics` --- [//]: # (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.
