Michael Bolin db51df0f44 ci: support signed macOS release promotion (#22737)
## Why

`rust-release.yml` can create unsigned macOS artifacts for external
signing, but there was no signed resume path after those artifacts
returned from a secure enclave. Release operators need a way to reuse
the first run artifacts, ingest signed macOS binaries and DMGs, and
continue the normal signed release path without rebuilding every
platform or treating handoff assets as final release assets.

## How this is meant to be used

First, start the release as an unsigned macOS build against the release
tag:

```shell
gh workflow run rust-release.yml \
  --repo openai/codex \
  --ref rust-vX.Y.Z \
  -f release_mode=build_unsigned
```

That run builds the normal Linux/Windows artifacts and publishes
unsigned macOS handoff artifacts. The unsigned macOS binaries are then
copied to the secure enclave, signed and notarized there, packaged as a
signed handoff archive, and uploaded back to the GitHub Release for the
same tag.

The signed handoff asset should contain either target directories such
as `aarch64-apple-darwin/` and `x86_64-apple-darwin/`, or artifact
directories such as `aarch64-apple-darwin-app-server/`. The promote
workflow accepts either layout. The directories should contain the
signed binaries and, for primary macOS bundles, the signed and stapled
DMGs.

For example, after signing, upload the handoff asset to the release:

```shell
gh release upload rust-vX.Y.Z \
  signed-macos-rust-vX.Y.Z.tar.zst \
  --repo openai/codex \
  --clobber
```

Then start the promotion run. `unsigned_run_id` is the workflow run id
from the first `build_unsigned` run, and `signed_macos_asset` is the
exact Release asset name uploaded by the secure enclave:

```shell
gh workflow run rust-release.yml \
  --repo openai/codex \
  --ref rust-vX.Y.Z \
  -f release_mode=promote_signed \
  -f unsigned_run_id=1234567890 \
  -f signed_macos_asset=signed-macos-rust-vX.Y.Z.tar.zst \
  -f signed_macos_sha256=<sha256>
```

The `signed_macos_sha256` input is optional, but when provided the
promotion run verifies the handoff archive before unpacking it. The
promotion run also validates that `unsigned_run_id` points to a
successful manual `rust-release` run for the same tag and commit before
importing artifacts.

## What Changed

- Add explicit manual `release_mode` values for `build_unsigned` and
`promote_signed` while keeping `sign_macos` as a deprecated
compatibility input.
- Add promote inputs for `unsigned_run_id`, `signed_macos_asset`, and
optional `signed_macos_sha256`.
- Add a `stage-signed-macos` job that downloads the signed handoff asset
from the GitHub Release, verifies signed binaries and stapled DMGs,
repacks normal macOS release artifacts, and builds macOS Python runtime
wheels.
- Teach the release job to download Part 1 artifacts from the unsigned
run, discard unsigned macOS staging artifacts, re-upload promoted Linux
and Windows artifacts for npm staging, and then run the signed release
tail.
- Validate that `unsigned_run_id` points to a successful manual
`rust-release` run for the same tag and commit before importing
artifacts.
- Limit unsigned macOS artifact upload to the unsigned build path so
normal signed releases do not publish unsigned handoff binaries.
- Clean up unsigned and signed handoff release assets after successful
promotion.

## Verification

- Parsed `.github/workflows/rust-release.yml` with Ruby YAML loading.

npm i -g @openai/codex
or brew install --cask codex

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

Install globally with your preferred package manager:

# 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
