## Summary - add `ProcessOwnedCodeModeSessionProvider` and logical session generation/rebinding state - add the supervised child-process connection, reader/writer tasks, and driver state machine - make dropped execute/wait/open callers cancellation-safe with explicit ownership handoff and durable cleanup - validate cell/delegate lifecycle state and reject invalid protocol transitions - add end-to-end stdio coverage for delegates, cancellation, frame limits, child loss, stale generations, replacement, and long-lived sessions ## Why This final stage exposes the process-owned client only after the wire protocol, host-safe runtime, and standalone host are independently in place. Transport failure is fail-stop: the client closes local state, cancels callbacks, reaps the child, and lazily rebuilds a fresh host generation rather than transactionally recovering the old connection. ## Stack This is **4 of 4** in the process-owned code-mode session stack. - Depends on #30111 - Full stack: #30108 → #30110 → #30111 → this PR ## Validation - `just test -p codex-code-mode -p codex-code-mode-host` — 86 passed - `just fix -p codex-code-mode` - `just fix -p codex-code-mode-host` - `just bazel-lock-update` - `just bazel-lock-check` - `bazel test //codex-rs/code-mode:code-mode-unit-tests //codex-rs/code-mode-host:code-mode-host-unit-tests //codex-rs/code-mode-host:code-mode-host-stdio-test //codex-rs/code-mode-protocol:code-mode-protocol-unit-tests` — 4/4 passed - `just fmt`

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.
