## Why
The VS Code extension and desktop app do not need the full TUI binary,
and `codex-app-server` is materially smaller than standalone `codex`. We
still want to publish it as an official release artifact, but building
it by tacking another `--bin` onto the existing release `cargo build`
invocations would lengthen those jobs.
This change keeps `codex-app-server` on its own release bundle so it can
build in parallel with the existing `codex` and helper bundles.
## What changed
- Made `.github/workflows/rust-release.yml` bundle-aware so each macOS
and Linux MUSL target now builds either the existing `primary` bundle
(`codex` and `codex-responses-api-proxy`) or a standalone `app-server`
bundle (`codex-app-server`).
- Preserved the historical artifact names for the primary macOS/Linux
bundles so `scripts/stage_npm_packages.py` and
`codex-cli/scripts/install_native_deps.py` continue to find release
assets under the paths they already expect, while giving the new
app-server artifacts distinct names.
- Added a matching `app-server` bundle to
`.github/workflows/rust-release-windows.yml`, and updated the final
Windows packaging job to download, sign, stage, and archive
`codex-app-server.exe` alongside the existing release binaries.
- Generalized the shared signing actions in
`.github/actions/linux-code-sign/action.yml`,
`.github/actions/macos-code-sign/action.yml`, and
`.github/actions/windows-code-sign/action.yml` so each workflow row
declares its binaries once and reuses that list for build, signing, and
staging.
- Added `codex-app-server` to `.github/dotslash-config.json` so releases
also publish a generated DotSlash manifest for the standalone app-server
binary.
- Kept the macOS DMG focused on the existing `primary` bundle;
`codex-app-server` ships as the regular standalone archives and DotSlash
manifest.
## Verification
- Parsed the modified workflow and action YAML files locally with
`python3` + `yaml.safe_load(...)`.
- Parsed `.github/dotslash-config.json` locally with `python3` +
`json.loads(...)`.
- Reviewed the resulting release matrices, artifact names, and packaging
paths to confirm that `codex-app-server` is built separately on macOS,
Linux MUSL, and Windows, while the existing npm staging and Windows
`codex` zip bundling contracts remain intact.
Add a dmg target that bundles the codex and codex responses api proxy
binaries for MacOS. this target is signed and notarized.
Verified by triggering a build here:
https://github.com/openai/codex/actions/runs/20318136302/job/58367155205.
Downloaded the artifact and verified that the dmg is signed and
notarized, and the codex binary contained works as expected.
