Alpha release turnaround is currently limited by fat LTO in release builds. We want faster alpha publishing without changing optimization settings for stable artifacts.
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`
Benefits:
- Faster alpha build + publish latency
- No release-prep churn from committing temporary Cargo.toml LTO flips
- Stable/beta release behavior remains unchanged
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
## Summary
- keep wiremock MockServer handles alive through async assertions in
remote model suite tests
- assert /models request count in remote_models_hide_picker_only_models
- use a slightly higher parallel timing threshold on aarch64 while
keeping existing x86 threshold
## Validation
- just fmt
- targeted tests:
- cargo test -p codex-core --test all
suite::remote_models::remote_models_merge_replaces_overlapping_model --
--exact
- cargo test -p codex-core --test all
suite::remote_models::remote_models_hide_picker_only_models -- --exact
- cargo test -p codex-core --test all
suite::tool_parallelism::shell_tools_run_in_parallel -- --exact
- soak loop: 40 iterations of all three targeted tests
## Notes
- cargo test -p codex-core has one unrelated local-env failure in
shell_snapshot::tests::try_new_creates_and_deletes_snapshot_file from
exported certificate env content in this workspace.
- local bazel test //codex-rs/core:core-all-test failed to build due
missing rust-objcopy in this host toolchain.
The TODO in core/src/seatbelt.rs claimed that apply_patch still needed to
honor SandboxPolicy. That was true when the comment was added, but it is no
longer true.
Analysis:
- The TODO was introduced in commit 5a0ad5ab8f (PR #1762), when seatbelt code
was split out of exec.rs.
- apply_patch sandboxing was later implemented in commit 355cded1ab
(PR #1705: "fix: run apply_patch calls through the sandbox").
- Today, apply_patch calls are routed through the tool orchestrator and
delegated to ApplyPatchRuntime, which executes via execute_env using the
active sandbox attempt policy.
- On macOS, the sandbox transform path for that execution still builds
seatbelt args with create_seatbelt_command_args(command, policy,
sandbox_policy_cwd), so the same SandboxPolicy gates apply_patch writes and
network behavior.
Because this behavior is already enforced, the TODO is stale and removing it
avoids implying missing sandbox coverage where none exists.
No functional behavior change; comment-only cleanup.
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.
During thread/fork, the new rollout includes the fork’s own session_meta
plus copied history that can contain older session_meta entries from the
source thread. thread/list was overwriting metadata on later
session_meta lines, so a fork could be reported with the source thread’s
thread_id. This fix only uses the first session_meta, so the fork keeps
its own ID.

- update `codex-rs` workspace and `codex-core` crate to depend on the
extracted `hooks` crate and wire up the shared APIs
- ensure references, modules, and lockfile reflect the new crate layout
Testing
- Not run (not requested)
## Align with the new phase-1 design
Basically we know run phase 1 in parallel by considering:
* Max 64 rollouts
* Max 1 month old
* Consider the most recent first
This PR also adds stronger parallelization capabilities by detecting
stale jobs, retry policies, ownership of computation to prevent double
computations etc etc
As of this PR, `SessionServices` retains a
`Option<StartedNetworkProxy>`, if appropriate.
Now the `network` field on `Config` is `Option<NetworkProxySpec>`
instead of `Option<NetworkProxy>`.
Over in `Session::new()`, we invoke `NetworkProxySpec::start_proxy()` to
create the `StartedNetworkProxy`, which is a new struct that retains the
`NetworkProxy` as well as the `NetworkProxyHandle`. (Note that `Drop` is
implemented for `NetworkProxyHandle` to ensure the proxies are shutdown
when it is dropped.)
The `NetworkProxy` from the `StartedNetworkProxy` is threaded through to
the appropriate places.
