A code-mode cell is a single JavaScript execution that can produce output, call tools, wait for asynchronous work, resume, or be terminated. This PR extracts the existing per-cell run loop into a dedicated actor that owns the cell’s lifecycle state. It is primarily an ownership change rather than a new lifecycle contract: existing behavior now has one clear implementation boundary. ### Architecture The session service remains responsible for session-wide concerns: allocating cell IDs, storing shared values, creating cells, and routing requests to them. Once a cell is created, its execution state belongs to its actor. Callers interact with the actor through a handle. The actor receives two kinds of input: runtime events and control requests. A single event loop serializes these inputs and applies the lifecycle rules. It tracks the current observer—the caller waiting for an update—along with accumulated output, outstanding callbacks, runtime state, yield deadlines, and termination progress. Observation, termination, completion, and cleanup therefore have one consistent owner. When the runtime has no immediately runnable work and is waiting only on timers or tool results, the actor can return accumulated output and information about outstanding tool calls while keeping the cell available to resume. On completion or termination, it performs the appropriate callback cleanup before publishing the final result and removing the cell from the session. A small host interface connects the actor to session-owned facilities such as tool dispatch, notifications, stored values, and final cell removal, keeping those responsibilities outside the actor itself. ### Why Previously, cell lifecycle state and coordination lived alongside session management. The actor boundary makes each cell a self-contained state machine with a single writer, while the service becomes a registry and adapter around it. This makes lifecycle behavior easier to reason about and test in isolation. It also establishes a clean boundary for later changing where cells run or how they communicate without recreating their lifecycle rules.

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.
