We are looking to speed up build times for alpha releases, but we do not
want to completely compromise on runtime performance by shipping debug
builds. This PR changes our CI so that alpha releases build with
`lto="thin"` instead of `lto="fat"`.
Specifically, this change keeps `[profile.release] lto = "fat"` as the
default in `Cargo.toml`, but overrides LTO in CI using
`CARGO_PROFILE_RELEASE_LTO`:
- `rust-release.yml`: use `thin` for `-alpha` tags, otherwise `fat`
- `shell-tool-mcp.yml`: use `thin` for `-alpha` versions, otherwise
`fat`
Tradeoffs:
- Alpha binaries may be somewhat larger and/or slightly slower than
fat-LTO builds
- LTO policy now lives in workflow logic for two pipelines, so
consistency must be maintained across both files
Note `CARGO_PROFILE_<name>_LTO` is documented on
https://doc.rust-lang.org/cargo/reference/environment-variables.html#configuration-environment-variables.
https://github.com/openai/codex/pull/11318 introduced logic to publish
platform artifacts as separate npm packages (for example,
`@openai/codex-darwin-arm64`, `@openai/codex-linux-x64`, etc.). That
requires provisioning and maintaining multiple package entries in npm,
which we want to avoid.
We still need to keep the package-size mitigation (platform-specific
payloads), but we want that layout to live under a single npm package
namespace (`@openai/codex`) using dist-tags.
We also need to preserve pre-release workflows where users install
`@openai/codex@alpha` and get platform-appropriate binaries.
Additionally, we want GitHub Release assets to group Codex npm tarballs
together, so platform tarballs should follow the same `codex-npm-*`
filename prefix as the main Codex tarball.
## Release Strategy (New Scheme)
We publish **one npm package name for Codex binaries** (`@openai/codex`)
and use **dist-tags** to select platform-specific payloads. This avoids
creating separate platform package names while keeping the package size
split by platform.
### What gets published
#### Mainline release (`x.y.z`)
- `@openai/codex@latest` (meta package)
- `@openai/codex@darwin-arm64`
- `@openai/codex@darwin-x64`
- `@openai/codex@linux-arm64`
- `@openai/codex@linux-x64`
- `@openai/codex@win32-arm64`
- `@openai/codex@win32-x64`
- `@openai/codex-responses-api-proxy@latest`
- `@openai/codex-sdk@latest`
#### Alpha release (`x.y.z-alpha.N`)
- `@openai/codex@alpha` (meta package)
- `@openai/codex@alpha-darwin-arm64`
- `@openai/codex@alpha-darwin-x64`
- `@openai/codex@alpha-linux-arm64`
- `@openai/codex@alpha-linux-x64`
- `@openai/codex@alpha-win32-arm64`
- `@openai/codex@alpha-win32-x64`
- `@openai/codex-responses-api-proxy@alpha`
- `@openai/codex-sdk@alpha`
As an example, the `package.json` for `@openai/codex@alpha` (using
`0.99.0-alpha.17` as the `version`) would be:
```
{
"name": "@openai/codex",
"version": "0.99.0-alpha.17",
"license": "Apache-2.0",
"bin": {
"codex": "bin/codex.js"
},
"type": "module",
"engines": {
"node": ">=16"
},
"files": [
"bin"
],
"repository": {
"type": "git",
"url": "git+https://github.com/openai/codex.git",
"directory": "codex-cli"
},
"packageManager": "pnpm@10.28.2+sha512.41872f037ad22f7348e3b1debbaf7e867cfd448f2726d9cf74c08f19507c31d2c8e7a11525b983febc2df640b5438dee6023ebb1f84ed43cc2d654d2bc326264",
"optionalDependencies": {
"@openai/codex-linux-x64": "npm:@openai/codex@0.99.0-alpha.17-linux-x64",
"@openai/codex-linux-arm64": "npm:@openai/codex@0.99.0-alpha.17-linux-arm64",
"@openai/codex-darwin-x64": "npm:@openai/codex@0.99.0-alpha.17-darwin-x64",
"@openai/codex-darwin-arm64": "npm:@openai/codex@0.99.0-alpha.17-darwin-arm64",
"@openai/codex-win32-x64": "npm:@openai/codex@0.99.0-alpha.17-win32-x64",
"@openai/codex-win32-arm64": "npm:@openai/codex@0.99.0-alpha.17-win32-arm64"
}
}
```
Note that the keys in `optionalDependencies` have "clean" names, but the
values have the tag embedded.
### Important note
**Note:** Because we never created the new platform package names on npm
(for example,
`@openai/codex-darwin-arm64`) since #11318 landed, there are no extra
npm packages to clean up.
## What changed
### 1. Stage platform tarballs as `@openai/codex` with platform-specific
versions
File: `codex-cli/scripts/build_npm_package.py`
- Added `CODEX_NPM_NAME = "@openai/codex"` and platform metadata
`npm_tag` values:
- `darwin-arm64`, `darwin-x64`, `linux-arm64`, `linux-x64`,
`win32-arm64`, `win32-x64`
- For platform package staging (`codex-<platform>` inputs), switched
generated `package.json` from:
- `name = @openai/codex-<platform>`
to:
- `name = @openai/codex`
- Added `compute_platform_package_version(version, platform_tag)` so
platform tarballs have unique
versions (`<release-version>-<platform-tag>`), which is required because
npm forbids re-publishing
the same `name@version`.
### 2. Point meta package optional dependencies at dist-tags on
`@openai/codex`
File: `codex-cli/scripts/build_npm_package.py`
- Updated `optionalDependencies` generation for the main `codex` package
to use npm alias syntax:
- key remains alias package name (for example,
`@openai/codex-darwin-arm64`) so runtime lookup behavior is unchanged
- value now resolves to `@openai/codex` by dist-tag
- Stable releases emit tags like `npm:@openai/codex@darwin-arm64`.
- Alpha releases (`x.y.z-alpha.N`) emit tags like
`npm:@openai/codex@alpha-darwin-arm64`.
### 3. Publish with per-tarball dist-tags in release CI
File: `.github/workflows/rust-release.yml`
- Reworked npm publish logic to derive the publish tag per tarball
filename:
- platform tarballs publish with `<platform>` tags for stable releases
- platform tarballs publish with `alpha-<platform>` tags for alpha
releases
- top-level tarballs (`codex`, `codex-responses-api-proxy`, `codex-sdk`)
continue using
the existing channel tag policy (`latest` implicit for stable, `alpha`
for alpha)
- Added fail-fast behavior for unexpected tarball names to avoid silent
mispublishes.
### 4. Normalize Codex platform tarball filenames for GitHub Release
grouping
Files: `scripts/stage_npm_packages.py`,
`.github/workflows/rust-release.yml`
- Renamed staged platform tarball filenames from:
- `codex-linux-<arch>-npm-<version>.tgz`
- `codex-darwin-<arch>-npm-<version>.tgz`
- `codex-win32-<arch>-npm-<version>.tgz`
- To:
- `codex-npm-linux-<arch>-<version>.tgz`
- `codex-npm-darwin-<arch>-<version>.tgz`
- `codex-npm-win32-<arch>-<version>.tgz`
This keeps all Codex npm artifacts grouped under a common `codex-npm-`
prefix in GitHub Releases.
### 5. Documentation update
File: `codex-cli/scripts/README.md`
- Updated staging docs to clarify that platform-native variants are
published as dist-tagged
`@openai/codex` artifacts rather than separate npm package names.
## Resulting behavior
- Mainline release:
- `@openai/codex@latest` resolves the meta package
- meta package optional dependencies resolve
`@openai/codex@<platform-tag>`
- Alpha release:
- users can continue installing `@openai/codex@alpha`
- alpha meta package optional dependencies resolve
`@openai/codex@alpha-<platform-tag>`
- Release assets:
- Codex npm tarballs share `codex-npm-` prefix for cleaner grouping in
GitHub Releases
This preserves platform-specific payload distribution while avoiding
separate npm package names and
improves release-asset discoverability.
## Validation notes
- Verified staged `package.json` output for stable and alpha meta
packages includes expected alias targets.
- Verified staged platform package manifests are `name=@openai/codex`
with unique platform-suffixed versions.
- Verified publish tag derivation maps renamed platform tarballs to
expected stable and alpha dist-tags.
Given that we have https://github.com/openai/codex/pull/10977, the
existing "Verify config schema fixture" step seems unnecessary. Further,
because it happens as part of the `tag-check` job (which is meant to be
fast), it slows down the entire build process because it delays the more
expensive steps from starting.
## Summary
This PR introduces a gated Bubblewrap (bwrap) Linux sandbox path. The
curent Linux sandbox path relies on in-process restrictions (including
Landlock). Bubblewrap gives us a more uniform filesystem isolation
model, especially explicit writable roots with the option to make some
directories read-only and granular network controls.
This is behind a feature flag so we can validate behavior safely before
making it the default.
- Added temporary rollout flag:
- `features.use_linux_sandbox_bwrap`
- Preserved existing default path when the flag is off.
- In Bubblewrap mode:
- Added internal retry without /proc when /proc mount is not permitted
by the host/container.
Currently, our `npm publish` logic is failing.
There were a number of things that were merged recently that seemed to
contribute to this situation, though I think we have fixed most of them,
but this one stands out:
https://github.com/openai/codex/pull/10115
As best I can tell, we tried to fix the pnpm version to a specific hash,
but we did not do it consistently (though `shell-tool-mcp/package.json`
had it specified twice...), so for this PR, I ran:
```
$ git ls-files | grep package.json
codex-cli/package.json
codex-rs/responses-api-proxy/npm/package.json
package.json
sdk/typescript/package.json
shell-tool-mcp/package.json
```
and ensured that all of them now have this line:
```json
"packageManager": "pnpm@10.28.2+sha512.41872f037ad22f7348e3b1debbaf7e867cfd448f2726d9cf74c08f19507c31d2c8e7a11525b983febc2df640b5438dee6023ebb1f84ed43cc2d654d2bc326264"
```
I also went and deleted all of the `corepack` stuff that was added by
https://github.com/openai/codex/pull/10115.
If someone can explain why we need it and verify it does not break `npm
publish`, then we can bring it back.
This updates the CI workflows for shell-tool-mcp to use the pnpm version
from package.json and print it in the build for verification.
I have read the CLA Document and I hereby sign the CLA
I needed to upgrade bazel one to get gnullvm artifacts and then noticed
monorepo had drifted forward. They should move in lockstep. Also 1.93
already shipped so we can try that instead.
Add a `.sqlite` database to be used to store rollout metatdata (and
later logs)
This PR is phase 1:
* Add the database and the required infrastructure
* Add a backfill of the database
* Persist the newly created rollout both in files and in the DB
* When we need to get metadata or a rollout, consider the `JSONL` as the
source of truth but compare the results with the DB and show any errors
This add a new crate, `codex-network-proxy`, a local network proxy
service used by Codex to enforce fine-grained network policy (domain
allow/deny) and to surface blocked network events for interactive
approvals.
- New crate: `codex-rs/network-proxy/` (`codex-network-proxy` binary +
library)
- Core capabilities:
- HTTP proxy support (including CONNECT tunneling)
- SOCKS5 proxy support (in the later PR)
- policy evaluation (allowed/denied domain lists; denylist wins;
wildcard support)
- small admin API for polling/reload/mode changes
- optional MITM support for HTTPS CONNECT to enforce “limited mode”
method restrictions (later PR)
Will follow up integration with codex in subsequent PRs.
## Testing
- `cd codex-rs && cargo build -p codex-network-proxy`
- `cd codex-rs && cargo run -p codex-network-proxy -- proxy`
## Summary
Upgrade GitHub Actions to their latest versions to ensure compatibility
with Node 24, as Node 20 will reach end-of-life in April 2026.
## Changes
| Action | Old Version(s) | New Version | Release | Files |
|--------|---------------|-------------|---------|-------|
| `actions/cache` |
[`v4`](https://github.com/actions/cache/releases/tag/v4) |
[`v5`](https://github.com/actions/cache/releases/tag/v5) |
[Release](https://github.com/actions/cache/releases/tag/v5) | bazel.yml

## Context
Per [GitHub's
announcement](https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/),
Node 20 is being deprecated and runners will begin using Node 24 by
default starting March 4th, 2026.
### Why this matters
- **Node 20 EOL**: April 2026
- **Node 24 default**: March 4th, 2026
- **Action**: Update to latest action versions that support Node 24
### Security Note
Actions that were previously pinned to commit SHAs remain pinned to SHAs
(updated to the latest release SHA) to maintain the security benefits of
immutable references.
### Testing
These changes only affect CI/CD workflow configurations and should not
impact application functionality. The workflows should be tested by
running them on a branch before merging.

Follow up to #8956; publish schema on new release to stable URL.
Also canonicalize schema (sort keys) when writing. This avoids reliance
on default `schema_rs` behavior and makes the schema easier to read.
As explained in `codex-rs/core/BUILD.bazel`, including the repo's own
`AGENTS.md` is a hack to get some tests passing. We should fix this
properly, but I wanted to put stake in the ground ASAP to get `just
bazel-remote-test` working and then add a job to `bazel.yml` to ensure
it keeps working.
This PR configures Codex CLI so it can be built with
[Bazel](https://bazel.build) in addition to Cargo. The `.bazelrc`
includes configuration so that remote builds can be done using
[BuildBuddy](https://www.buildbuddy.io).
If you are familiar with Bazel, things should work as you expect, e.g.,
run `bazel test //... --keep-going` to run all the tests in the repo,
but we have also added some new aliases in the `justfile` for
convenience:
- `just bazel-test` to run tests locally
- `just bazel-remote-test` to run tests remotely (currently, the remote
build is for x86_64 Linux regardless of your host platform). Note we are
currently seeing the following test failures in the remote build, so we
still need to figure out what is happening here:
```
failures:
suite::compact::manual_compact_twice_preserves_latest_user_messages
suite::compact_resume_fork::compact_resume_after_second_compaction_preserves_history
suite::compact_resume_fork::compact_resume_and_fork_preserve_model_history_view
```
- `just build-for-release` to build release binaries for all
platforms/architectures remotely
To setup remote execution:
- [Create a buildbuddy account](https://app.buildbuddy.io/) (OpenAI
employees should also request org access at
https://openai.buildbuddy.io/join/ with their `@openai.com` email
address.)
- [Copy your API key](https://app.buildbuddy.io/docs/setup/) to
`~/.bazelrc` (add the line `build
--remote_header=x-buildbuddy-api-key=YOUR_KEY`)
- Use `--config=remote` in your `bazel` invocations (or add `common
--config=remote` to your `~/.bazelrc`, or use the `just` commands)
## CI
In terms of CI, this PR introduces `.github/workflows/bazel.yml`, which
uses Bazel to run the tests _locally_ on Mac and Linux GitHub runners
(we are working on supporting Windows, but that is not ready yet). Note
that the failures we are seeing in `just bazel-remote-test` do not occur
on these GitHub CI jobs, so everything in `.github/workflows/bazel.yml`
is green right now.
The `bazel.yml` uses extra config in `.github/workflows/ci.bazelrc` so
that macOS CI jobs build _remotely_ on Linux hosts (using the
`docker://docker.io/mbolin491/codex-bazel` Docker image declared in the
root `BUILD.bazel`) using cross-compilation to build the macOS
artifacts. Then these artifacts are downloaded locally to GitHub's macOS
runner so the tests can be executed natively. This is the relevant
config that enables this:
```
common:macos --config=remote
common:macos --strategy=remote
common:macos --strategy=TestRunner=darwin-sandbox,local
```
Because of the remote caching benefits we get from BuildBuddy, these new
CI jobs can be extremely fast! For example, consider these two jobs that
ran all the tests on Linux x86_64:
- Bazel 1m37s
https://github.com/openai/codex/actions/runs/20861063212/job/59940545209?pr=8875
- Cargo 9m20s
https://github.com/openai/codex/actions/runs/20861063192/job/59940559592?pr=8875
For now, we will continue to run both the Bazel and Cargo jobs for PRs,
but once we add support for Windows and running Clippy, we should be
able to cutover to using Bazel exclusively for PRs, which should still
speed things up considerably. We will probably continue to run the Cargo
jobs post-merge for commits that land on `main` as a sanity check.
Release builds will also continue to be done by Cargo for now.

Use the contents of the commit message from the commit associated with
the tag (that contains the version bump) as the release notes by writing
them to a file and then specifying the file as the `body_path` of
`softprops/action-gh-release@v2`.
## Summary
Forked repositories inherit GitHub Actions workflows including scheduled
ones. This causes:
1. **Wasted Actions minutes** - Scheduled workflows run on forks even
though they will fail
2. **Failed runs** - Workflows requiring `CODEX_OPENAI_API_KEY` fail
immediately on forks
3. **Noise** - Fork owners see failed workflow runs they didn't trigger
This PR adds `if: github.repository == 'openai/codex'` guards to
workflows that should only run on the upstream repository.
### Affected workflows
| Workflow | Trigger | Issue |
|----------|---------|-------|
| `rust-release-prepare` | `schedule: */4 hours` | Runs 6x/day on every
fork |
| `close-stale-contributor-prs` | `schedule: daily` | Runs daily on
every fork |
| `issue-deduplicator` | `issues: opened` | Requires
`CODEX_OPENAI_API_KEY` |
| `issue-labeler` | `issues: opened` | Requires `CODEX_OPENAI_API_KEY` |
### Note
`cla.yml` already has this guard (`github.repository_owner ==
'openai'`), so it was not modified.
## Test plan
- [ ] Verify workflows still run correctly on `openai/codex`
- [ ] Verify workflows are skipped on forks (can check via Actions tab
on any fork)
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.
