## Summary - Record bounded connection, request, and process lifecycle metrics. - Report active gauges from callbacks on every collection, including delta exports. - Serialize active-count updates so concurrent starts and finishes cannot publish stale values. - Serialize process exit, explicit termination, and shutdown through the process registry so exactly one completion result wins. - Keep the implementation small with single-owner RAII guards and one real OTLP/HTTP integration test using the existing `wiremock` dependency. ## Root cause Process exit and session shutdown previously used cloned completion state. That avoided duplicate emission, but it duplicated lifecycle ownership and made the ordering harder to reason about. The process registry mutex already defines the lifecycle ordering, so the final implementation stores the metric guard and termination flag directly on the process entry. Whichever path claims the entry first owns the completion result. Production metric export uses delta temporality. Event-only synchronous gauge recordings disappear after the next collection when no count changes, so active counts now use observable callbacks that report current state on every collection. The cleanup also removes the constant `result="accepted"` connection tag, redundant route and response assertions, a custom HTTP collector, and fallback initialization machinery that did not add behavior. ## Stack Review and land this stack in order: 1. #27466 — trace exec-server JSON-RPC requests 2. #27467 — record bounded connection, request, and process lifecycle metrics **(this PR)** 3. #27470 — observe remote registration and Noise rendezvous lifecycle ## Validation - `just test -p codex-exec-server --lib` (158 passed) - `just test -p codex-cli --test exec_server` (3 passed) - `just test -p codex-otel observable_gauge_is_collected_on_every_delta_snapshot` (1 passed) - `CARGO_BUILD_JOBS=1 just fix -p codex-otel -p codex-exec-server` - `just fmt` - `git diff --check`

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
