Adds `--branch` to `codex cloud exec` to set base branch.
- Inline response recording during streaming: `run_turn` now records
items as they arrive instead of building a `ProcessedResponseItem` list
and post‑processing via `process_items`.
- Simplify turn handling: `handle_output_item_done` returns the
follow‑up signal + optional tool future; `needs_follow_up` is set only
there, and in‑flight tool futures are drained once at the end (errors
logged, no extra state writes).
- Flattened stream loop: removed `process_items` indirection and the
extra output queue
- - Tests: relaxed `tool_parallelism::tool_results_grouped` to allow any
completion order while still requiring matching call/output IDs.
- Use the codex-api crate to introduce models endpoint. 
- Add `models` to codex core tests helpers
- Add `ModelsInfo` for the endpoint return type
Seems like a nice field to have, and also VSCE does render this one.
VSCE renders `codex/event/stream_error` (automatically retried, e.g.
`"Reconnecting... 1/n"`) and `codex/event/error` (terminal errors)
differently, so add `will_retry` on ErrorNotification to indicate this.
**Summary**
- Shortcut toggle using `?` in `handle_shortcut_overlay_key` fails to
trigger on some platforms (notably Windows). Current match requires
`KeyCode::Char('?')` with `KeyModifiers::NONE`. Some terminals set
`SHIFT` when producing `?` (since it is typically `Shift + /`), so the
strict `NONE` check prevents toggling.

**Impact**
- On Windows consoles/terminals, pressing `?` with an empty composer
often does nothing, leading to inconsistent UX compared to macOS/Linux.

**Root Cause**
- Crossterm/terminal backends report modifiers inconsistently across
platforms. Generating `?` may include `SHIFT`. The code enforces
`modifiers == NONE`, so valid `?` presses with `SHIFT` are ignored.
AltGr keyboards may also surface as `ALT`.

**Repro Steps**
- Open the TUI, ensure the composer is empty.
- Press `?`.
- Expected: Shortcut overlay toggles.
- Actual (Windows frequently): No toggle occurs.

**Fix Options**
- Option 1 (preferred): Accept `?` regardless of `SHIFT`, but reject
`CONTROL` and `ALT`.
- Rationale: Keeps behavior consistent across platforms with minimal
code change.
	- Example change:
		- Before: matching `KeyModifiers::NONE` only.
		- After: allow `SHIFT`, disallow `CONTROL | ALT`.
		- Suggested condition:
			```rust
			let toggles = matches!(key_event.code, KeyCode::Char('?'))
&& !key_event.modifiers.intersects(KeyModifiers::CONTROL |
KeyModifiers::ALT)
					&& self.is_empty();
			```

- Option 2: Platform-specific handling (Windows vs non-Windows).
- Implement two variants or conditional branches using `#[cfg(target_os
= "windows")]`.
- On Windows, accept `?` with `SHIFT`; on other platforms, retain
current behavior.
- Trade-off: Higher maintenance burden and code divergence for limited
benefit.

close #5495
…#7615)

The caller should decide whether wrapping the policy in `Arc<RwLock>` is
necessary. This should make openai/codex#7609 a
bit smoother.

- `exec_policy_for()` -> `load_exec_policy_for_features()`
- introduce `load_exec_policy()` that does not take `Features` as an arg
- both return `Result<Policy, ExecPolicyError>` instead of
Result<Arc<RwLock<Policy>>, ExecPolicyError>`

This simplifies the tests as they have no need for `Arc<RwLock>`.
## Summary
This PR introduces an End to End test suite for apply-patch, so we can
easily validate behavior against other implementations as well.

## Testing
- [x] These are tests
- Introduce `with_remote_overrides` and update
`refresh_available_models`
- Put `auth_manager` instead of `auth_mode` on `models_manager`
- Remove `ShellType` and `ReasoningLevel` to use already existing
structs
adding execpolicy support into the `posix` mcp

pull plan type from the usage endpoint, persist it in session state /
tui state, and propagate through rate limit snapshots
- This PR wires `with_remote_overrides` and make the
`construct_model_families` an async function
- Moves getting model family a level above to keep the function `sync`
- Updates the tests to local, offline, and `sync` helper for model

Adds cli commands for getting the status of cloud tasks, and for
getting/applying the diffs from same.
## Summary
- move the workspace justfile to the repository root for easier
discovery
- set the just working directory to codex-rs so existing recipes still
run in the Rust workspace

## Testing

## Summary
This PR is heavily based on #4017, which contains the core logic for the
fix. To reduce the risk, we are first introducing it only on windows. We
can then expand to wsl / other environments as needed, and then tackle
net new files.

## Testing
- [x] added unit tests in apply-patch
- [x] add integration tests to apply_patch_cli.rs

Also load skills from /REPO_ROOT/codex/skills.
This fixes two issues with the OTEL HTTP exporter:

1. **Runtime panic with async reqwest client**

The `opentelemetry_sdk` `BatchLogProcessor` spawns a dedicated OS thread
that uses `futures_executor::block_on()` rather than tokio's runtime.
When the async reqwest client's timeout mechanism calls
`tokio::time::sleep()`, it panics with "there is no reactor running,
must be called from the context of a Tokio 1.x runtime".

The fix is to use `reqwest::blocking::Client` instead, which doesn't
depend on tokio for timeouts. However, the blocking client creates its
own internal tokio runtime during construction, which would panic if
built from within an async context. We wrap the construction in
`tokio::task::block_in_place()` to handle this.

2. **mTLS certificate handling**

The HTTP client wasn't properly configured for mTLS, matching the fixes
previously done for the model provider client:

- Added `.tls_built_in_root_certs(false)` when using a custom CA
certificate to ensure only our CA is trusted
- Added `.https_only(true)` when using client identity
- Added `rustls-tls` feature to ensure rustls is used (required for
`Identity::from_pem()` to work correctly)
Previous to this change, large `EscalateRequest` payloads exceeded the
kernel send buffer, causing our single `sendmsg(2)` call (with attached
FDs) to be split and retried without proper control handling; this led
to `EINVAL`/broken pipe in the
`handle_escalate_session_respects_run_in_sandbox_decision()` test when
using an `env` with large contents.

**Before:** `AsyncSocket::send_with_fds()` called `send_json_message()`,
which called `send_message_bytes()`, which made one `socket.sendmsg()`
call followed by additional `socket.send()` calls, as necessary:


https://github.com/openai/codex/blob/2e4a40252157751765dff176b35c692df8a9fb4e/codex-rs/exec-server/src/posix/socket.rs#L198-L209

**After:** `AsyncSocket::send_with_fds()` now calls
`send_stream_frame()`, which calls `send_stream_chunk()` one or more
times. Each call to `send_stream_chunk()` calls `socket.sendmsg()`.

In the previous implementation, the subsequent `socket.send()` writes
had no control information associated with them, whereas in the new
`send_stream_chunk()` implementation, a fresh `MsgHdr` (using
`with_control()`, as appropriate) is created for `socket.sendmsg()` each
time.

Additionally, with this PR, stream sending attaches `SCM_RIGHTS` only on
the first chunk, and omits control data when there are no FDs, allowing
oversized payloads to deliver correctly while preserving FD limits and
error checks.
## Summary
- Updated the rmcp client flag's documentation in config.md file
- changed it from `experimental_use_rmcp_client` to `rmcp_client`
Removed experimental Rust MCP client option from config.
Update install and contributing guides to use the root justfile helpers
(`just fmt`, `just fix -p <crate>`, and targeted tests) instead of the
older cargo fmt/clippy/test instructions that have been in place since
459363e. This matches the justfile relocation to the repo root in
952d6c9 and the current lint/test workflow for CI (see
`.github/workflows/rust-ci.yml`).
When I put up openai/codex#7617 for review,
initially I started seeing failures on the `ubuntu-24.04` runner used
for Rust test runs for the `x86_64-unknown-linux-gnu` architecture. Chat
suggested a number of things that could be removed to save space, which
seems to help.
…ixes (#7680)

As noted in the code comment, we introduced a key fix for `brew` in
Homebrew/brew#21157 that Codex needs, but it has
not hit stable yet, so we update our CI job to use latest `brew` from
`origin/main`.

This is necessary for the new integration tests introduced in
openai/codex#7617.
…(#7617)

This PR introduces integration tests that run
[codex-shell-tool-mcp](https://www.npmjs.com/package/@openai/codex-shell-tool-mcp)
as a user would. Note that this requires running our fork of Bash, so we
introduce a [DotSlash](https://dotslash-cli.com/) file for `bash` so
that we can run the integration tests on multiple platforms without
having to check the binaries into the repository. (As noted in the
DotSlash file, it is slightly more heavyweight than necessary, which may
be worth addressing as disk space in CI is limited:
openai/codex#7678.)

To start, this PR adds two tests:

- `list_tools()` makes the `list_tools` request to the MCP server and
verifies we get the expected response
- `accept_elicitation_for_prompt_rule()` defines a `prefix_rule()` with
`decision="prompt"` and verifies the elicitation flow works as expected

Though the `accept_elicitation_for_prompt_rule()` test **only works on
Linux**, as this PR reveals that there are currently issues when running
the Bash fork in a read-only sandbox on Linux. This will have to be
fixed in a follow-up PR.

Incidentally, getting this test run to correctly on macOS also requires
a recent fix we made to `brew` that hasn't hit a mainline release yet,
so getting CI green in this PR required
openai/codex#7680.

We should not have any `PathBuf` fields in `ConfigToml` or any of the
transitive structs we include, as we should use `AbsolutePathBuf`
instead so that we do not have to keep track of the file from which
`ConfigToml` was loaded such that we need it to resolve relative paths
later when the values of `ConfigToml` are used.

I only found two instances of this: `experimental_instructions_file` and
`experimental_compact_prompt_file`. Incidentally, when these were
specified as relative paths, they were resolved against `cwd` rather
than `config.toml`'s parent, which seems wrong to me. I changed the
behavior so they are resolved against the parent folder of the
`config.toml` being parsed, which we get "for free" due to the
introduction of `AbsolutePathBufGuard ` in
openai/codex#7796.

While it is not great to change the behavior of a released feature,
these fields are prefixed with `experimental_`, which I interpret to
mean we have the liberty to change the contract.

For reference:

- `experimental_instructions_file` was introduced in
openai/codex#1803
- `experimental_compact_prompt_file` was introduced in
openai/codex#5959
### Summary
* Make `app_server.list_models` to be non-blocking and consumers (i.e.
extension) can manage the flow themselves.
* Force config to use remote models and therefore fetch codex-auto model
list.
- Load models from static file as a fallback
- Make API users use this file directly
- Add tests to make sure updates to the file always serialize
- Batch read ACL creation for online/offline sandbox user
- creates a new ACL helper process that is long-lived and runs in the
background
- uses a mutex so that only one helper process is running at a time.

This PR does various types of cleanup before I can proceed with more
ambitious changes to config loading.

First, I noticed duplicated code across these two methods:


https://github.com/openai/codex/blob/774bd9e432fa2e0f4e059e97648cf92216912e19/codex-rs/core/src/config/mod.rs#L314-L324


https://github.com/openai/codex/blob/774bd9e432fa2e0f4e059e97648cf92216912e19/codex-rs/core/src/config/mod.rs#L334-L344

This has now been consolidated in
`load_config_as_toml_with_cli_overrides()`.

Further, I noticed that `Config::load_with_cli_overrides()` took two
similar arguments:


https://github.com/openai/codex/blob/774bd9e432fa2e0f4e059e97648cf92216912e19/codex-rs/core/src/config/mod.rs#L308-L311

The difference between `cli_overrides` and `overrides` was not
immediately obvious to me. At first glance, it appears that one should
be able to be expressed in terms of the other, but it turns out that
some fields of `ConfigOverrides` (such as `cwd` and
`codex_linux_sandbox_exe`) are, by design, not configurable via a
`.toml` file or a command-line `--config` flag.

That said, I discovered that many callers of
`Config::load_with_cli_overrides()` were passing
`ConfigOverrides::default()` for `overrides`, so I created two separate
methods:

- `Config::load_with_cli_overrides(cli_overrides: Vec<(String,
TomlValue)>)`
- `Config::load_with_cli_overrides_and_harness_overrides(cli_overrides:
Vec<(String, TomlValue)>, harness_overrides: ConfigOverrides)`

The latter has a long name, as it is _not_ what should be used in the
common case, so the extra typing is designed to draw attention to this
fact. I tried to update the existing callsites to use the shorter name,
where possible.

Further, in the cases where `ConfigOverrides` is used, usually only a
limited subset of fields are actually set, so I updated the declarations
to leverage `..Default::default()` where possible.

1. Remove PUBLIC skills and introduce SYSTEM skills embedded in the
binary and installed into $CODEX_HOME/skills/.system at startup.
2. Skills are now always enabled (feature flag removed).
3. Update skills/list to accept forceReload and plumb it through (not
used by clients yet).
Instead of failing to start Codex, clearly call out that N skills did
not load and provide warnings so that the user may fix them.

/>
Introduce `ConfigBuilder` as an alternative to our existing `Config`
constructors.

I noticed that the existing constructors,
`Config::load_with_cli_overrides()` and
`Config::load_with_cli_overrides_and_harness_overrides()`, did not take
`codex_home` as a parameter, which can be a problem.

Historically, when Codex was purely a CLI, we wanted to be extra sure
that the creation of `codex_home` was always done via
`find_codex_home()`, so we did not expose `codex_home` as a parameter
when creating `Config` in business logic. But in integration tests,
`codex_home` nearly always needs to be configured (as a temp directory),
which is why callers would have to go through
`Config::load_from_base_config_with_overrides()` instead.

Now that the Codex harness also functions as an app server, which could
conceivably load multiple threads where `codex_home` is parameterized
differently in each one, I think it makes sense to make this
configurable. Going to a builder pattern makes it more flexible to
ensure an arbitrary permutation of options can be set when constructing
a `Config` while using the appropriate defaults for the options that
aren't set explicitly.

Ultimately, I think this should make it possible for us to make
`Config::load_from_base_config_with_overrides()` private because all
integration tests should be able to leverage `ConfigBuilder` instead.
Though there could be edge cases, so I'll pursue that migration after we
get through the current config overhaul.

1. Reintroduce feature flags for skills;
2. UI tweaks (truncate descriptions, better validation error display).
Over in `config_loader/macos.rs`, we were doing this complicated `mod`
thing to expose one version of `load_managed_admin_config_layer()` for
Mac:


https://github.com/openai/codex/blob/580c59aa9af61cb4bffb5b204bd16a5dcc4bc911/codex-rs/core/src/config_loader/macos.rs#L4-L5

While exposing a trivial implementation for non-Mac:


https://github.com/openai/codex/blob/580c59aa9af61cb4bffb5b204bd16a5dcc4bc911/codex-rs/core/src/config_loader/macos.rs#L110-L117

That was being used like this:


https://github.com/openai/codex/blob/580c59aa9af61cb4bffb5b204bd16a5dcc4bc911/codex-rs/core/src/config_loader/layer_io.rs#L47-L48

This PR simplifies that callsite in `layer_io.rs` to just be:

```rust
    #[cfg(not(target_os = "macos"))]
    let managed_preferences = None;
```

And updates `config_loader/mod.rs` so we only pull in `macos.rs` on Mac:

```rust
#[cfg(target_os = "macos")]
mod macos;
```

This simplifies `macos.rs` considerably, though it looks like a big
change because everything gets unindented and reformatted because we can
drop the whole `mod native` thing now.

This is some minor API cleanup that will make it easier to use
`AbsolutePathBuf` in more places in a subsequent PR.
This pull request makes a small update to the session picker
documentation for `codex resume`. The main change clarifies how to view
the original working directory (CWD) for sessions and when the Git
branch is shown.

- The session picker now displays the recorded Git branch when
available, and instructions are added for showing the original working
directory by using the `--all` flag, which also disables CWD filtering
and adds a `CWD` column.

This is a significant change to how layers of configuration are applied.
In particular, the `ConfigLayerStack` now has two important fields:

- `layers: Vec<ConfigLayerEntry>`
- `requirements: ConfigRequirements`

We merge `TomlValue`s across the layers, but they are subject to
`ConfigRequirements` before creating a `Config`.

How I would review this PR:

- start with `codex-rs/app-server-protocol/src/protocol/v2.rs` and note
the new variants added to the `ConfigLayerSource` enum:
`LegacyManagedConfigTomlFromFile` and `LegacyManagedConfigTomlFromMdm`
- note that `ConfigLayerSource` now has a `precedence()` method and
implements `PartialOrd`
- `codex-rs/core/src/config_loader/layer_io.rs` is responsible for
loading "admin" preferences from `/etc/codex/managed_config.toml` and
MDM. Because `/etc/codex/managed_config.toml` is now deprecated in favor
of `/etc/codex/requirements.toml` and `/etc/codex/config.toml`, we now
include some extra information on the `LoadedConfigLayers` returned in
`layer_io.rs`.
- `codex-rs/core/src/config_loader/mod.rs` has major changes to
`load_config_layers_state()`, which is what produces `ConfigLayerStack`.
The docstring has the new specification and describes the various layers
that will be loaded and the precedence order.
- It uses the information from `LoaderOverrides` "twice," both in the
spirit of legacy support:
- We use one instances to derive an instance of `ConfigRequirements`.
Currently, the only field in `managed_config.toml` that contributes to
`ConfigRequirements` is `approval_policy`. This PR introduces
`Constrained::allow_only()` to support this.
- We use a clone of `LoaderOverrides` to derive
`ConfigLayerSource::LegacyManagedConfigTomlFromFile` and
`ConfigLayerSource::LegacyManagedConfigTomlFromMdm` layers, as
appropriate. As before, this ends up being a "best effort" at enterprise
controls, but is enforcement is not guaranteed like it is for
`ConfigRequirements`.
- Now we only create a "user" layer if `$CODEX_HOME/config.toml` exists.
(Previously, a user layer was always created for `ConfigLayerStack`.)
- Similarly, we only add a "session flags" layer if there are CLI
overrides.
- `config_loader/state.rs` contains the updated implementation for
`ConfigLayerStack`. Note the public API is largely the same as before,
but the implementation is quite different. We leverage the fact that
`ConfigLayerSource` is now `PartialOrd` to ensure layers are in the
correct order.
- A `Config` constructed via `ConfigBuilder.build()` will use
`load_config_layers_state()` to create the `ConfigLayerStack` and use
the associated `ConfigRequirements` when constructing the `Config`
object.
- That said, a `Config` constructed via
`Config::load_from_base_config_with_overrides()` does _not_ yet use
`ConfigBuilder`, so it creates a `ConfigRequirements::default()` instead
of loading a proper `ConfigRequirements`. I will fix this in a
subsequent PR.

Then the following files are mostly test changes:

```
codex-rs/app-server/tests/suite/v2/config_rpc.rs
codex-rs/core/src/config/service.rs
codex-rs/core/src/config_loader/tests.rs
```

Again, because we do not always include "user" and "session flags"
layers when the contents are empty, `ConfigLayerStack` sometimes has
fewer layers than before (and the precedence order changed slightly),
which is the main reason integration tests changed.

Vital Work Items for Nori

Based on the upstream changes, here are recommended action items for the nori project:

  1. Test ACP Configuration Compatibility - The configuration loading refactor is the most substantial change. Verify that our ACP-specific configuration layers work correctly with the new ConfigLayerStack and constraint-based loading system.

  2. Review Configuration File Paths - Check if we use /etc/codex/managed_config.toml anywhere in nori-specific code or documentation. Update to the new paths (/etc/codex/requirements.toml and /etc/codex/config.toml) if needed.

  3. Validate Cloud Exec Changes - If nori exposes or extends cloud execution features, test the new git-ref resolver and --branch flag to ensure compatibility with our ACP fork.

  4. Update Integration Tests - The new async unit tests for cloud exec suggest changes to the testing patterns. Review and potentially adopt similar testing approaches for ACP-specific features.

  5. Configuration Precedence Documentation - Document how the new ConfigLayerSource precedence ordering interacts with any nori-specific configuration layers or overrides.

  6. Snapshot Test Review - As noted in the merge instructions, run cargo insta review after merge to update any snapshot tests affected by the configuration changes.


Recommendation: Prioritize items #1 and #2 as they represent the most significant architectural changes that could impact core functionality.
