felixxia-oai db8927a8e2 Deflake realtime handoff steering test (#28300)
## Summary
- keep the realtime mock websocket open for the handoff steering test
after scripted responses
- avoid racing the mock server close before the standalone handoff
append is observed, which was showing up as a Windows timeout in CI

__Details__:
Failures in samples seem to be caused by:
1. The mock websocket sends conversation.handoff.requested.
2. The mock immediately closes the websocket because
start_websocket_server(...) defaults to close_after_requests: true.
3. On Windows, that close often surfaces as os error 10053 / 10054.
4. The realtime stream shuts down before the routed handoff finishes
creating/steering the follow-up request.
5. The test waits for the expected follow-up event and times out.

The PR changes only step 2: for this test, the mock websocket stays open
after sending the scripted handoff event. The same handoff event is
still sent, and the test still asserts the important steering behavior:
1. first Responses request has the original prompt
2. first request does not contain realtime delegation
3. second Responses request does contain the realtime delegation

## Validation
- `just fmt`
- `just test -p codex-core --test all
suite::realtime_conversation::inbound_handoff_request_steers_active_turn`

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.

Using Codex with your ChatGPT plan
