hefuc-oai d9cf931d0e [codex] Add managed new-thread model settings (#29683)
## Why

Admins need persistent defaults for the model, reasoning effort, and
service tier shown when the Desktop App creates a new thread. These are
initialization defaults rather than runtime constraints: the App should
use them to initialize its draft while still allowing a user to make an
explicit selection.

The app-server therefore needs to expose the managed values before
thread creation without changing `thread/start` behavior for other
clients.

## What changed

- Parse `model`, `model_reasoning_effort`, and `service_tier` from
`[models.new_thread]` in `requirements.toml`.
- Compose the `models` requirements through the existing
requirements-layer precedence rules.
- Expose the resolved values through `configRequirements/read` as
`requirements.models.newThread`.
- Add the corresponding app-server protocol types and regenerate the
JSON and TypeScript schema fixtures.
- Document the new `configRequirements/read` fields in the app-server
README.

## Scope

This PR is data plumbing only. It does not apply these values during
`thread/start` and does not change thread creation for existing
app-server clients, resumed or forked sessions, internal or subagent
sessions, `codex exec`, or the TUI. A companion Desktop App change owns
draft initialization, sends the effective settings for ordinary and
prewarmed starts, and preserves explicit user changes.

## Validation

- Requirements deserialization coverage for `[models.new_thread]`
- Requirements-layer precedence coverage
- App-server API mapping coverage
- `configRequirements/read` integration coverage
- Regenerated app-server JSON and TypeScript schema fixtures

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.

You can also use Codex with an API key, but this requires additional setup.
