## Summary
Move the marketplace remove implementation into shared core logic so
both the CLI command and follow-up app-server RPC can reuse the same
behavior.
This change:
- adds a shared `codex_core::plugins::remove_marketplace(...)` flow
- moves validation, config removal, and installed-root deletion out of
the CLI
- keeps the CLI as a thin wrapper over the shared implementation
- adds focused core coverage for the shared remove path
## Validation
- `just fmt`
- focused local coverage for the shared remove path
- heavier follow-up validation deferred to stacked PR CI
## Summary
This changes Codex logout so managed ChatGPT auth is revoked against
AuthAPI before local auth state is removed. CLI logout, TUI `/logout`,
and the app-server account logout path now use the token-revoking logout
flow instead of only deleting `auth.json` / credential store state.
## Root Cause
Logout previously cleared only local auth storage. That removed Codex's
local credentials but did not ask the backend to invalidate the
refresh/access token state associated with a managed ChatGPT login.
## Behavior
For managed ChatGPT auth, logout sends the stored refresh token to
`https://auth.openai.com/oauth/revoke` with `token_type_hint:
refresh_token` and the Codex OAuth client id, then deletes all local
auth stores after revocation succeeds. If only an access token is
available, it falls back to revoking that access token. API key auth and
externally supplied `chatgptAuthTokens` are still only cleared locally
because Codex does not own a refresh token for those modes.
Revocation failures are fail-closed: if Codex cannot load stored auth or
the backend revoke call fails, logout returns an error and leaves local
auth in place so the user can retry instead of silently clearing local
state while backend tokens remain valid.
## Validation
ran local version of `codex-cli` with staging overrides/harness for auth
ran `codex login` then `codex logout`:
saw auth.json clear and backend revocation endpoints were called
```
POST /oauth/revoke
status: 200
revoking access token
should clear auth session
clearing auth session due to token revocation
successfully revoked session and access token
CANONICAL-API-LINE Response: status='200' method='POST' path='/oauth/revoke
```

## Summary
- Add `codex-model-provider` as the runtime home for model-provider
behavior that does not belong in `codex-core`, `codex-login`, or
`codex-api`.
- The new crate wraps configured `ModelProviderInfo` in a
`ModelProvider` trait object that can resolve the API provider config,
provider-scoped auth manager, and request auth provider for each call.
- This centralizes provider auth behavior in one place today, and gives
us an extension point for future provider-specific auth, model listing,
request setup, and related runtime behavior.
## Tests
Ran tests manually to make sure that provider auth under different
configs still work as expected.

Adds new events for streaming apply_patch changes from responses api.
This is to enable clients to show progress during file writes.
Caveat: This does not work with apply_patch in function call mode, since
that required adding streaming json parsing.
## Summary
- Add best-effort auto-upgrade for user-configured Git marketplaces
recorded in `config.toml`.
- Track the last activated Git revision with `last_revision` so
unchanged marketplace sources skip clone work.
- Trigger the upgrade from plugin startup and `plugin/list`, while
preserving existing fail-open plugin behavior with warning logs rather
than new user-visible errors.
## Details
- Remote configured marketplaces use `git ls-remote` to compare the
source/ref against the recorded revision.
- Upgrades clone into a staging directory, validate that
`.agents/plugins/marketplace.json` exists and that the manifest name
matches the configured marketplace key, then atomically activate the new
root.
- Local `.agents/plugins/marketplace.json` marketplaces remain live
filesystem state and are not auto-pulled.
- Existing non-curated plugin cache refresh is kicked after successful
marketplace root upgrades.
## Validation
- `just write-config-schema`
- `cargo test -p codex-core marketplace_upgrade`
- `cargo check -p codex-cli -p codex-app-server`
- `just fix -p codex-core`
Did not run the complete `cargo test` suite because the repo
instructions require asking before a full core workspace run.
## Summary
- Add an MCP server environment setting with local as the default.
- Thread the default through config serialization, schema generation,
and existing config fixtures.

## Summary
This PR significantly improves the standalone installer experience.
The main changes are:
1. We now install the codex binary and other dependencies in a
subdirectory under CODEX_HOME.
(`CODEX_HOME/packages/standalone/releases/...`)
2. We replace the `codex.js` launcher that npm/bun rely on with logic in
the Rust binary that automatically resolves its dependencies (like
ripgrep)
## Motivation
A few design constraints pushed this work.
1. Currently, the entrypoint to codex is through `codex.js`, which
forces a node dependency to kick off our rust app. We want to move away
from this so that the entrypoint to codex does not rely on node or
external package managers.
2. Right now, the native script adds codex and its dependencies directly
to user PATH. Given that codex is likely to add more binary dependencies
than ripgrep, we want a solution which does not add arbitrary binaries
to user PATH -- the only one we want to add is the `codex` command
itself.
3. We want upgrades to be atomic. We do not want scenarios where
interrupting an upgrade command can move codex into undefined state (for
example, having a new codex binary but an old ripgrep binary). This was
~possible with the old script.
4. Currently, the Rust binary uses heuristics to determine which
installer created it. These heuristics are flaky and are tied to the
`codex.js` launcher. We need a more stable/deterministic way to
determine how the binary was installed for standalone.
5. We do not want conflicting codex installations on PATH. For example,
the user installing via npm, then installing via brew, then installing
via standalone would make it unclear which version of codex is being
launched and make it tough for us to determine the right upgrade
command.
## Design
### Standalone package layout
Standalone installs now live under `CODEX_HOME/packages/standalone`:
```text
$CODEX_HOME/
packages/
standalone/
current -> releases/0.111.0-x86_64-unknown-linux-musl
releases/
0.111.0-x86_64-unknown-linux-musl/
codex
codex-resources/
rg
```
where `standalone/current` is a symlink to a release directory.
On Windows, the release directory has the same shape, with `.exe` names
and Windows helpers in `codex-resources`:
```text
%CODEX_HOME%\
packages\
standalone\
current -> releases\0.111.0-x86_64-pc-windows-msvc
releases\
0.111.0-x86_64-pc-windows-msvc\
codex.exe
codex-resources\
rg.exe
codex-command-runner.exe
codex-windows-sandbox-setup.exe
```
This gives us:
- atomic upgrades because we can fully stage a release before switching
`standalone/current`
- a stable way for the binary to recognize a standalone install from its
canonical `current_exe()` path under CODEX_HOME
- a clean place for binary dependencies like `rg`, Windows sandbox
helpers, and, in the future, our custom `zsh` etc
### Command location
On Unix, we add a symlink at `~/.local/bin/codex` which points directly
to the `$CODEX_HOME/packages/standalone/current/codex` binary. This
becomes the main entrypoint for the CLI.
On Windows, we store the link at
`%LOCALAPPDATA%\Programs\OpenAI\Codex\bin`.
### PATH persistence
This is a tricky part of the PR, as there's no ~super reliable way to
ensure that we end up on PATH without significant tradeoffs.
Most Unix variants will have `~/.local/bin` on PATH already, which means
we *should* be fine simply registering the command there in most cases.
However, there are cases where this is not the case. In these cases, we
directly edit the profile depending on the shell we're in.
- macOS zsh: `~/.zprofile`
- macOS bash: `~/.bash_profile`
- Linux zsh: `~/.zshrc`
- Linux bash: `~/.bashrc`
- fallback: `~/.profile`
On Windows, we update the User `Path` environment variable directly and
we don't need to worry about shell profiles.
### Standalone runtime detection
This PR adds a new shared crate, `codex-install-context`, which computes
install ownership once per process and caches it in a `OnceLock`.
That context includes:
- install manager (`Standalone`, `Npm`, `Bun`, `Brew`, `Other`)
- the managed standalone release directory, when applicable
- the managed standalone `codex-resources` directory, when present
- the resolved `rg_command`
The standalone path is detected by canonicalizing `current_exe()`,
canonicalizing CODEX_HOME via `find_codex_home()`, and checking whether
the binary is running from under
`$CODEX_HOME/packages/standalone/releases`.
We intentionally do not use a release metadata file. The binary path is
the source of truth.
### Dependency resolution
For standalone installs, `grep_files` now resolves bundled `rg` from
`codex-resources` next to the Codex binary.
For npm/bun/brew/other installs, `grep_files` falls back to resolving
`rg` from PATH.
For Windows standalone installs, Windows sandbox helpers are still found
as direct siblings when present. If they are not direct siblings, the
lookup also checks the sibling `codex-resources` directory.
### TUI update path
The TUI now has `UpdateAction::StandaloneUnix` and
`UpdateAction::StandaloneWindows`, which rerun the standalone install
commands.
Unix update command:
```sh
sh -c "curl -fsSL https://chatgpt.com/codex/install.sh | sh"
```
Windows update command:
```powershell
powershell -c "irm https://chatgpt.com/codex/install.ps1|iex"
```
The Windows updater runs PowerShell directly. We do this because `cmd
/C` would parse the `|iex` as a cmd pipeline instead of passing it to
PowerShell.
## Additional installer behavior
- standalone installs now warn about conflicting npm/bun/brew-managed
`codex` installs and offer to uninstall them
- same-version reruns do not redownload the release if it is already
staged locally
## Testing
Installer smoke tests run:
- macOS: fresh install into isolated `HOME` and `CODEX_HOME` with
`scripts/install/install.sh --release latest`
- macOS: reran the installer against the same isolated install to verify
the same-version/update path and PATH block idempotence
- macOS: verified the installed `codex --version` and bundled
`codex-resources/rg --version`
- Windows: parsed `scripts/install/install.ps1` with PowerShell via
`[scriptblock]::Create(...)`
- Windows: verified the standalone update action builds a direct
PowerShell command and does not route the `irm ...|iex` command through
`cmd /C`

## Changes
Allows sandboxes to restrict overall network access while granting
access to specific unix sockets on mac.
## Details
- `codex sandbox macos`: adds a repeatable `--allow-unix-socket` option.
- `codex-sandboxing`: threads explicit Unix socket roots into the macOS
Seatbelt profile generation.
- Preserves restricted network behavior when only Unix socket IPC is
requested, and preserves full network behavior when full network is
already enabled.
## Verification
- `cargo test -p codex-cli -p codex-sandboxing`
- `cargo build -p codex-cli --bin codex`
- verified that `codex sandbox macos --allow-unix-socket /tmp/test.sock
-- test-client` grants access as expected
## Summary
- Port marketplace source support into the shared core marketplace-add
flow
- Support local marketplace directory sources
- Support direct `marketplace.json` URL sources
- Persist the new source types in config/schema and cover them in CLI
and app-server tests
## Validation
- `cargo test -p codex-core marketplace_add`
- `cargo test -p codex-cli marketplace_add`
- `cargo test -p codex-app-server marketplace_add`
- `just write-config-schema`
- `just fmt`
- `just fix -p codex-core`
- `just fix -p codex-cli`
## Context
Current `main` moved marketplace-add behavior into shared core code and
still assumed only git-backed sources. This change keeps that structure
but restores support for local directories and direct manifest URLs in
the shared path.
## Summary
Move `codex marketplace add` onto a shared core implementation so the
CLI and app-server path can use one source of truth.
This change:
- adds shared marketplace-add orchestration in `codex-core`
- switches the CLI command to call that shared implementation
- removes duplicated CLI-only marketplace add helpers
- preserves focused parser and add-path coverage while moving the shared
behavior into core tests
## Why
The new `marketplace/add` RPC should reuse the same underlying
marketplace-add flow as the CLI. This refactor lands that consolidation
first so the follow-up app-server PR can be mostly protocol and handler
wiring.
## Validation
- `cargo test -p codex-core marketplace_add`
- `cargo test -p codex-cli marketplace_cmd`
- `just fix -p codex-core`
- `just fix -p codex-cli`
- `just fmt`
## Why
For more advanced MCP usage, we want the model to be able to emit
parallel MCP tool calls and have Codex execute eligible ones
concurrently, instead of forcing all MCP calls through the serial block.
The main design choice was where to thread the config. I made this
server-level because parallel safety depends on the MCP server
implementation. Codex reads the flag from `mcp_servers`, threads the
opted-in server names into `ToolRouter`, and checks the parsed
`ToolPayload::Mcp { server, .. }` at execution time. That avoids relying
on model-visible tool names, which can be incomplete in
deferred/search-tool paths or ambiguous for similarly named
servers/tools.
## What was added
Added `supports_parallel_tool_calls` for MCP servers.
Before:
```toml
[mcp_servers.docs]
command = "docs-server"
```
After:
```toml
[mcp_servers.docs]
command = "docs-server"
supports_parallel_tool_calls = true
```
MCP calls remain serial by default. Only tools from opted-in servers are
eligible to run in parallel. Docs also now warn to enable this only when
the server’s tools are safe to run concurrently, especially around
shared state or read/write races.
## Testing
Tested with a local stdio MCP server exposing real delay tools. The
model/Responses side was mocked only to deterministically emit two MCP
calls in the same turn.
Each test called `query_with_delay` and `query_with_delay_2` with `{
"seconds": 25 }`.
| Build/config | Observed | Wall time |
| --- | --- | --- |
| main with flag enabled | serial | `58.79s` |
| PR with flag enabled | parallel | `31.73s` |
| PR without flag | serial | `56.70s` |
PR with flag enabled showed both tools start before either completed;
main and PR-without-flag completed the first delay before starting the
second.
Also added an integration test.
Additional checks:
- `cargo test -p codex-tools` passed
- `cargo test -p codex-core
mcp_parallel_support_uses_exact_payload_server` passed
- `git diff --check` passed
## Summary
- Update the marketplace add local-source integration test to pass an
explicit relative local path.
- Keep the change test-only; no CLI source parsing behavior changes.
## Tests
- cargo fmt -p codex-cli
- cargo test -p codex-cli --test marketplace_add
## Impact
- Production behavior is unchanged.
- No impact to feedback upload logic, DAGs, exports, or downstream
pipelines.

Added a new top-level `codex marketplace add` command for installing
plugin marketplaces into Codex’s local marketplace cache.
This change adds source parsing for local directories, GitHub shorthand,
and git URLs, supports optional `--ref` and git-only `--sparse` checkout
paths, stages the source in a temp directory, validates the marketplace
manifest, and installs it under
`$CODEX_HOME/marketplaces/<marketplace-name>`
Included tests cover local install behavior in the CLI and marketplace
discovery from installed roots in core. Scoped formatting and fix passes
were run, and targeted CLI/core tests passed.
## Summary
- preserve legacy Windows elevated sandbox behavior for existing
policies
- add elevated-only support for split filesystem policies that can be
represented as readable-root overrides, writable-root overrides, and
extra deny-write carveouts
- resolve those elevated filesystem overrides during sandbox transform
and thread them through setup and policy refresh
- keep failing closed for explicit unreadable (`none`) carveouts and
reopened writable descendants under read-only carveouts
- for explicit read-only-under-writable-root carveouts, materialize
missing carveout directories during elevated setup before applying the
deny-write ACL
- document the elevated vs restricted-token support split in the core
README
## Example
Given a split filesystem policy like:
```toml
":root" = "read"
":cwd" = "write"
"./docs" = "read"
"C:/scratch" = "write"
```
the elevated backend now provisions the readable-root overrides,
writable-root overrides, and extra deny-write carveouts during setup and
refresh instead of collapsing back to the legacy workspace-only shape.
If a read-only carveout under a writable root is missing at setup time,
elevated setup creates that carveout as an empty directory before
applying its deny-write ACE; otherwise the sandboxed command could
create it later and bypass the carveout. This is only for explicit
policy carveouts. Best-effort workspace protections like `.codex/` and
`.agents/` still skip missing directories.
A policy like:
```toml
"/workspace" = "write"
"/workspace/docs" = "read"
"/workspace/docs/tmp" = "write"
```
still fails closed, because the elevated backend does not reopen
writable descendants under read-only carveouts yet.

Addresses #16421
Problem: Resumed interactive sessions exited before new token usage
skipped all footer lines, hiding the `codex resume` continuation
command.
It's not clear whether this was an intentional design choice, but I
think it's reasonable to expect this message under these circumstances.
Solution: Compose token usage and resume hints independently so
resumable sessions still print the continuation command with zero usage.
## Summary
- reduce public module visibility across Rust crates, preferring private
or crate-private modules with explicit crate-root public exports
- update external call sites and tests to use the intended public crate
APIs instead of reaching through module trees
- add the module visibility guideline to AGENTS.md
## Validation
- `cargo check --workspace --all-targets --message-format=short` passed
before the final fix/format pass
- `just fix` completed successfully
- `just fmt` completed successfully
- `git diff --check` passed
This PR adds root and profile config switches to omit the generated
`<permissions instructions>` and `<apps_instructions>` prompt blocks
while keeping both enabled by default, and it gates both the initial
developer-context injection and later permissions diff injection so
turning the permissions block off stays effective across turn-context
overrides.
Also added a prompt debug tool that can be used as `codex debug
prompt-input "hello"` and dumps the constructed items list.
Stacked on #16508.
This removes the temporary `codex-core` / `codex-login` re-export shims
from the ownership split and rewrites callsites to import directly from
`codex-model-provider-info`, `codex-models-manager`, `codex-api`,
`codex-protocol`, `codex-feedback`, and `codex-response-debug-context`.
No behavior change intended; this is the mechanical import cleanup layer
split out from the ownership move.

Addresses #16655
Problem: `codex login --api-key` failed in Clap before Codex could show
the deprecation guidance.
Solution: Allow the hidden `--api-key` flag to parse with zero or one
values so both forms reach the `--with-api-key` message.
## Why
This finishes the config-type move out of `codex-core` by removing the
temporary compatibility shim in `codex_core::config::types`. Callers now
depend on `codex-config` directly, which keeps these config model types
owned by the config crate instead of re-expanding `codex-core` as a
transitive API surface.
## What Changed
- Removed the `codex-rs/core/src/config/types.rs` re-export shim and the
`core::config::ApprovalsReviewer` re-export.
- Updated `codex-core`, `codex-cli`, `codex-tui`, `codex-app-server`,
`codex-mcp-server`, and `codex-linux-sandbox` call sites to import
`codex_config::types` directly.
- Added explicit `codex-config` dependencies to downstream crates that
previously relied on the `codex-core` re-export.
- Regenerated `codex-rs/core/config.schema.json` after updating the
config docs path reference.
## Why
`codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
which made downstream crates depend on `codex-core` as a proxy module
instead of the actual owner crate.
Removing those forwards makes crate boundaries explicit and lets leaf
crates drop unnecessary `codex-core` dependencies. In this PR, this
reduces the dependency on `codex-core` to `codex-login` in the following
files:
```
codex-rs/backend-client/Cargo.toml
codex-rs/mcp-server/tests/common/Cargo.toml
```
## What
- Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
`codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
`codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
`codex-tools`, and `codex-utils-path`.
- Delete the `default_client` forwarding shim in `codex-rs/core`.
- Update in-crate and downstream callsites to import directly from the
owning `codex-*` crate.
- Add direct Cargo dependencies where callsites now target the owner
crate, and remove `codex-core` from `codex-rs/backend-client`.
## Why
`codex-mcp` already owns the shared MCP API surface, including `auth`,
`McpConfig`, `CODEX_APPS_MCP_SERVER_NAME`, and tool-name helpers in
[`codex-rs/codex-mcp/src/mcp/mod.rs`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/codex-rs/codex-mcp/src/mcp/mod.rs#L1-L35).
Re-exporting that surface from `codex_core::mcp` gives downstream crates
two import paths for the same API and hides the real crate dependency.
This PR keeps `codex_core::mcp` focused on the local `McpManager`
wrapper in
[`codex-rs/core/src/mcp.rs`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/codex-rs/core/src/mcp.rs#L13-L40)
and makes consumers import shared MCP APIs from `codex_mcp` directly.
## What
- Remove the `codex_mcp::mcp` re-export surface from `core/src/mcp.rs`.
- Update `codex-core` internals plus `codex-app-server`, `codex-cli`,
and `codex-tui` test code to import MCP APIs from `codex_mcp::mcp`
directly.
- Add explicit `codex-mcp` dependencies where those crates now use that
API surface, and refresh `Cargo.lock`.
## Verification
- `just bazel-lock-check`
- `cargo test -p codex-core -p codex-cli -p codex-tui`
- `codex-cli` passed.
- `codex-core` still fails five unrelated config tests in
`core/src/config/config_tests.rs` (`approvals_reviewer_*` and
`smart_approvals_alias_*`).
- A broader `cargo test -p codex-core -p codex-app-server -p codex-cli
-p codex-tui` run previously hung in `codex-app-server` test
`in_process_start_uses_requested_session_source_for_thread_start`.
This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.
## Why
`argument-comment-lint` was green in CI even though the repo still had
many uncommented literal arguments. The main gap was target coverage:
the repo wrapper did not force Cargo to inspect test-only call sites, so
examples like the `latest_session_lookup_params(true, ...)` tests in
`codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.
This change cleans up the existing backlog, makes the default repo lint
path cover all Cargo targets, and starts rolling that stricter CI
enforcement out on the platform where it is currently validated.
## What changed
- mechanically fixed existing `argument-comment-lint` violations across
the `codex-rs` workspace, including tests, examples, and benches
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
`tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
`--all-targets` unless the caller explicitly narrows the target set
- fixed both wrappers so forwarded cargo arguments after `--` are
preserved with a single separator
- documented the new default behavior in
`tools/argument-comment-lint/README.md`
- updated `rust-ci` so the macOS lint lane keeps the plain wrapper
invocation and therefore enforces `--all-targets`, while Linux and
Windows temporarily pass `-- --lib --bins`
That temporary CI split keeps the stricter all-targets check where it is
already cleaned up, while leaving room to finish the remaining Linux-
and Windows-specific target-gated cleanup before enabling
`--all-targets` on those runners. The Linux and Windows failures on the
intermediate revision were caused by the wrapper forwarding bug, not by
additional lint findings in those lanes.
## Validation
- `bash -n tools/argument-comment-lint/run.sh`
- `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
- shell-level wrapper forwarding check for `-- --lib --bins`
- shell-level wrapper forwarding check for `-- --tests`
- `just argument-comment-lint`
- `cargo test` in `tools/argument-comment-lint`
- `cargo test -p codex-terminal-detection`
## Follow-up
- Clean up remaining Linux-only target-gated callsites, then switch the
Linux lint lane back to the plain wrapper invocation.
- Clean up remaining Windows-only target-gated callsites, then switch
the Windows lint lane back to the plain wrapper invocation.
This is the part 1 of 2 PRs that will delete the `tui` /
`tui_app_server` split. This part simply deletes the existing `tui`
directory and marks the `tui_app_server` feature flag as removed. I left
the `tui_app_server` feature flag in place for now so its presence
doesn't result in an error. It is simply ignored.
Part 2 will rename the `tui_app_server` directory `tui`. I did this as
two parts to reduce visible code churn.
## Summary
This PR makes Windows sandbox proxying enforceable by routing proxy-only
runs through the existing `offline` sandbox user and reserving direct
network access for the existing `online` sandbox user.
In brief:
- if a Windows sandbox run should be proxy-enforced, we run it as the
`offline` user
- the `offline` user gets firewall rules that block direct outbound
traffic and only permit the configured localhost proxy path
- if a Windows sandbox run should have true direct network access, we
run it as the `online` user
- no new sandbox identity is introduced
This brings Windows in line with the intended model: proxy use is not
just env-based, it is backed by OS-level egress controls. Windows
already has two sandbox identities:
- `offline`: intended to have no direct network egress
- `online`: intended to have full network access
This PR makes proxy-enforced runs use that model directly.
### Proxy-enforced runs
When proxy enforcement is active:
- the run is assigned to the `offline` identity
- setup extracts the loopback proxy ports from the sandbox env
- Windows setup programs firewall rules for the `offline` user that:
- block all non-loopback outbound traffic
- block loopback UDP
- block loopback TCP except for the configured proxy ports
- optionally allow broader localhost access when `allow_local_binding=1`
So the sandboxed process can only talk to the local proxy. It cannot
open direct outbound sockets or do local UDP-based DNS on its own.The
proxy then performs the real outbound network access outside that
restricted sandbox identity.
### Direct-network runs
When proxy enforcement is not active and full network access is allowed:
- the run is assigned to the `online` identity
- no proxy-only firewall restrictions are applied
- the process gets normal direct network access
### Unelevated vs elevated
The restricted-token / unelevated path cannot enforce per-identity
firewall policy by itself.
So for Windows proxy-enforced runs, we transparently use the logon-user
sandbox path under the hood, even if the caller started from the
unelevated mode. That keeps enforcement real instead of best-effort.

## Why
`PermissionProfile` should only describe the per-command permissions we
still want to grant dynamically. Keeping
`MacOsSeatbeltProfileExtensions` in that surface forced extra macOS-only
approval, protocol, schema, and TUI branches for a capability we no
longer want to expose.
## What changed
- Removed the macOS-specific permission-profile types from
`codex-protocol`, the app-server v2 API, and the generated
schema/TypeScript artifacts.
- Deleted the core and sandboxing plumbing that threaded
`MacOsSeatbeltProfileExtensions` through execution requests and seatbelt
construction.
- Simplified macOS seatbelt generation so it always includes the fixed
read-only preferences allowlist instead of carrying a configurable
profile extension.
- Removed the macOS additional-permissions UI/docs/test coverage and
deleted the obsolete macOS permission modules.
- Tightened `request_permissions` intersection handling so explicitly
empty requested read lists are preserved only when that field was
actually granted, avoiding zero-grant responses being stored as active
permissions.
For app-server websocket auth, support the two server-side mechanisms
from
PR #14847:
- `--ws-auth capability-token --ws-token-file /abs/path`
- `--ws-auth signed-bearer-token --ws-shared-secret-file /abs/path`
with optional `--ws-issuer`, `--ws-audience`, and
`--ws-max-clock-skew-seconds`
On the client side, add interactive remote support via:
- `--remote ws://host:port` or `--remote wss://host:port`
- `--remote-auth-token-env <ENV_VAR>`
Codex reads the bearer token from the named environment variable and
sends it
as `Authorization: Bearer <token>` during the websocket handshake.
Remote auth
tokens are only allowed for `wss://` URLs or loopback `ws://` URLs.
Testing:
- tested both auth methods manually to confirm connection success and
rejection for both auth types
## Summary
This change adds websocket authentication at the app-server transport
boundary and enforces it before JSON-RPC `initialize`, so authenticated
deployments reject unauthenticated clients during the websocket
handshake rather than after a connection has already been admitted.
During rollout, websocket auth is opt-in for non-loopback listeners so
we do not break existing remote clients. If `--ws-auth ...` is
configured, the server enforces auth during websocket upgrade. If auth
is not configured, non-loopback listeners still start, but app-server
logs a warning and the startup banner calls out that auth should be
configured before real remote use.
The server supports two auth modes: a file-backed capability token, and
a standard HMAC-signed JWT/JWS bearer token verified with the
`jsonwebtoken` crate, with optional issuer, audience, and clock-skew
validation. Capability tokens are normalized, hashed, and compared in
constant time. Short shared secrets for signed bearer tokens are
rejected at startup. Requests carrying an `Origin` header are rejected
with `403` by transport middleware, and authenticated clients present
credentials as `Authorization: Bearer <token>` during websocket upgrade.
## Validation
- `cargo test -p codex-app-server transport::auth`
- `cargo test -p codex-cli app_server_`
- `cargo clippy -p codex-app-server --all-targets -- -D warnings`
- `just bazel-lock-check`
Note: in the broad `cargo test -p codex-app-server
connection_handling_websocket` run, the touched websocket auth cases
passed, but unrelated Unix shutdown tests failed with a timeout in this
environment.

## Summary
- add `codex resume --include-non-interactive` to include
non-interactive sessions in the picker and `--last`
- keep current-provider and cwd filtering behavior unchanged
- replace the picker API boolean with a `SessionSourceFilter` enum to
avoid a boolean trap
## Tests
- `cargo test -p codex-cli`
- `cargo test -p codex-tui`
- `just fmt`
- `just fix -p codex-cli`
- `just fix -p codex-tui`
Migrate `cwd` and related session/config state to `AbsolutePathBuf` so
downstream consumers consistently see absolute working directories.
Add test-only `.abs()` helpers for `Path`, `PathBuf`, and `TempDir`, and
update branch-local tests to use them instead of
`AbsolutePathBuf::try_from(...)`.
For the remaining TUI/app-server snapshot coverage that renders absolute
cwd values, keep the snapshots unchanged and skip the Windows-only cases
where the platform-specific absolute path layout differs.
## Summary
- move macOS permission merging/intersection logic and tests from
`codex-core` into `codex-sandboxing`
- move seatbelt policy builders, permissions logic, SBPL assets, and
their tests into `codex-sandboxing`
- keep `codex-core` owning only the seatbelt spawn wrapper and switch
call sites to import the moved APIs directly
## Notes
- no re-exports added
- moved the seatbelt tests with the implementation so internal helpers
could stay private
- local verification is still finishing while this PR is open
## Summary
- add a new `codex-sandboxing` crate for sandboxing extraction work
- move the pure Linux sandbox argv builders and their unit tests out of
`codex-core`
- keep `core::landlock` as the spawn wrapper and update direct callers
to use `codex_sandboxing::landlock`
## Testing
- `cargo test -p codex-sandboxing`
- `cargo test -p codex-core landlock`
- `cargo test -p codex-cli debug_sandbox`
- `just argument-comment-lint`
## Notes
- this is step 1 of the move plan aimed at minimizing per-PR diffs
- no re-exports or no-op proxy methods were added
## Why
The argument-comment lint now has a packaged DotSlash artifact from
[#15198](https://github.com/openai/codex/pull/15198), so the normal repo
lint path should use that released payload instead of rebuilding the
lint from source every time.
That keeps `just clippy` and CI aligned with the shipped artifact while
preserving a separate source-build path for people actively hacking on
the lint crate.
The current alpha package also exposed two integration wrinkles that the
repo-side prebuilt wrapper needs to smooth over:
- the bundled Dylint library filename includes the host triple, for
example `@nightly-2025-09-18-aarch64-apple-darwin`, and Dylint derives
`RUSTUP_TOOLCHAIN` from that filename
- on Windows, Dylint's driver path also expects `RUSTUP_HOME` to be
present in the environment
Without those adjustments, the prebuilt CI jobs fail during `cargo
metadata` or driver setup. This change makes the checked-in prebuilt
wrapper normalize the packaged library name to the plain
`nightly-2025-09-18` channel before invoking `cargo-dylint`, and it
teaches both the wrapper and the packaged runner source to infer
`RUSTUP_HOME` from `rustup show home` when the environment does not
already provide it.
After the prebuilt Windows lint job started running successfully, it
also surfaced a handful of existing anonymous literal callsites in
`windows-sandbox-rs`. This PR now annotates those callsites so the new
cross-platform lint job is green on the current tree.
## What Changed
- checked in the current
`tools/argument-comment-lint/argument-comment-lint` DotSlash manifest
- kept `tools/argument-comment-lint/run.sh` as the source-build wrapper
for lint development
- added `tools/argument-comment-lint/run-prebuilt-linter.sh` as the
normal enforcement path, using the checked-in DotSlash package and
bundled `cargo-dylint`
- updated `just clippy` and `just argument-comment-lint` to use the
prebuilt wrapper
- split `.github/workflows/rust-ci.yml` so source-package checks live in
a dedicated `argument_comment_lint_package` job, while the released lint
runs in an `argument_comment_lint_prebuilt` matrix on Linux, macOS, and
Windows
- kept the pinned `nightly-2025-09-18` toolchain install in the prebuilt
CI matrix, since the prebuilt package still relies on rustup-provided
toolchain components
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` to
normalize host-qualified nightly library filenames, keep the `rustup`
shim directory ahead of direct toolchain `cargo` binaries, and export
`RUSTUP_HOME` when needed for Windows Dylint driver setup
- updated `tools/argument-comment-lint/src/bin/argument-comment-lint.rs`
so future published DotSlash artifacts apply the same nightly-filename
normalization and `RUSTUP_HOME` inference internally
- fixed the remaining Windows lint violations in
`codex-rs/windows-sandbox-rs` by adding the required `/*param*/`
comments at the reported callsites
- documented the checked-in DotSlash file, wrapper split, archive
layout, nightly prerequisite, and Windows `RUSTUP_HOME` requirement in
`tools/argument-comment-lint/README.md`
