## Why The Python and TypeScript SDKs launch the native Codex runtime directly, so they need to understand the same package layout that the release artifacts now use. Without this, SDK runtime wheels would keep carrying only a loose `bin/codex` plus ad hoc helper binaries, the TypeScript SDK would keep resolving the legacy optional-dependency layout, and bundled `codex-path` tools such as `rg` would not be prepended when the SDK starts Codex. ## What Changed - Stage `openai-codex-cli-bin` from a Codex package directory, including `codex-package.json`, `bin/`, `codex-resources/`, and `codex-path/`. - Make `stage-runtime` package-dir-only; legacy loose-binary wrapping now happens in `_runtime_setup.py` before calling the staging script. - Expose Python runtime helpers for the bundled package directory and `codex-path`, and prepend that path when `openai_codex` launches the installed runtime without duplicating Windows `Path`/`PATH` keys. - Teach the TypeScript SDK to resolve package-layout optional dependencies while keeping the legacy layout fallback, and preserve the existing Windows path variable casing when prepending `codex-path`. - Update the Rust release workflows to build Python runtime wheels from the generated Codex package directories instead of loose binaries. ## Test Plan - `python3 -m py_compile sdk/python/scripts/update_sdk_artifacts.py sdk/python/_runtime_setup.py sdk/python/src/openai_codex/client.py sdk/python-runtime/src/codex_cli_bin/__init__.py` - `uv run --frozen --project sdk/python --extra dev ruff check sdk/python/scripts/update_sdk_artifacts.py sdk/python/_runtime_setup.py sdk/python/src/openai_codex/client.py sdk/python/tests/test_artifact_workflow_and_binaries.py sdk/python-runtime/src/codex_cli_bin/__init__.py` - `uv run --frozen --project sdk/python --extra dev pytest sdk/python/tests/test_artifact_workflow_and_binaries.py` - `pnpm eslint src/exec.ts tests/exec.test.ts` - `pnpm test --runInBand tests/exec.test.ts`
Workflow Strategy
The workflows in this directory are split so that pull requests get fast, review-friendly signal while main still gets the full cross-platform verification pass.
Pull Requests
bazel.ymlis the main pre-merge verification path for Rust code. It runs Bazeltestand Bazelclippyon the supported Bazel targets, including the generated Rust test binaries needed to lint inline#[cfg(test)]code.rust-ci.ymlkeeps the Cargo-native PR checks intentionally small:cargo fmt --checkcargo shearargument-comment-linton Linux, macOS, and Windowstools/argument-comment-lintpackage tests when the lint or its workflow wiring changes
Post-Merge On main
bazel.ymlalso runs on pushes tomain. This re-verifies the merged Bazel path and helps keep the BuildBuddy caches warm.rust-ci-full.ymlis the full Cargo-native verification workflow. It keeps the heavier checks off the PR path while still validating them after merge:- the full Cargo
clippymatrix - the full Cargo
nextestmatrix via per-platform archive-backed shards - Windows ARM64 nextest archives cross-compiled on Windows x64, then replayed on native Windows ARM64 shards
- release-profile Cargo builds
- cross-platform
argument-comment-lint - Linux remote-env tests
- the full Cargo
Rule Of Thumb
- If a build/test/clippy check can be expressed in Bazel, prefer putting the PR-time version in
bazel.yml. - Keep
rust-ci.ymlfast enough that it usually does not dominate PR latency. - Reserve
rust-ci-full.ymlfor heavyweight Cargo-native coverage that Bazel does not replace yet.
