Shuo bb05c1f30f [codex] dedupe remote control account header (#29893)
## Why

Remote-control HTTP requests applied the authentication headers and then
appended `ChatGPT-Account-ID` again with
`reqwest::RequestBuilder::header`. Since reqwest appends, the wire
request could contain the same header twice. Intermediaries may coalesce
duplicate values into `uuid,uuid`, which is not a valid account ID.

## What changed

- Build remote-control request authentication headers in one place.
- Apply provider headers first, then use `HeaderMap::insert` for the
explicit account ID. This preserves the current account-ID precedence
and all other authentication headers while ensuring exactly one account
header is sent.
- Preserve duplicate HTTP headers in the test harness and assert exactly
one account header for enroll, refresh, list, and revoke requests.

## Validation

Added focused coverage for:

- Adding the explicit account header when the auth provider omits it.
- Replacing multiple provider-supplied account values, including a
differently cased header name.
- Preserving authorization and routing headers while replacing only the
account header.
- Rejecting invalid account header values before sending a request.
- Emitting exactly one account header for enroll, refresh, list, and
revoke requests.
- Maintaining header uniqueness across unauthorized recovery, retry, and
error-response paths.
- Emitting exactly one installation header for enroll and refresh
requests.

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

Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
