  • app-server: centralize AuthManager initialization (#16764) 
    Extract a shared helper that builds AuthManager from Config and applies
the forced ChatGPT workspace override in one place.

Create the shared AuthManager at MessageProcessor call sites so that
upcoming new transport's initialization can reuse the same handle, and
keep only external auth refresher wiring inside `MessageProcessor`.

Remove the now-unused `AuthManager::shared_with_external_auth` helper.

  • fix(guardian): fix ordering of guardian events (#16462) 
    Guardian events were emitted a bit out of order for CommandExecution
items. This would make it hard for the frontend to render a guardian
auto-review, which has this payload:
```
pub struct ItemGuardianApprovalReviewStartedNotification {
    pub thread_id: String,
    pub turn_id: String,
    pub target_item_id: String,
    pub review: GuardianApprovalReview,
    // FYI this is no longer a json blob
    pub action: Option<JsonValue>,
}
```

There is a `target_item_id` the auto-approval review is referring to,
but the actual item had not been emitted yet.

Before this PR:
- `item/autoApprovalReview/started`
- `item/autoApprovalReview/completed`, and if approved...
- `item/started`
- `item/completed`

After this PR:
- `item/started`
- `item/autoApprovalReview/started`
- `item/autoApprovalReview/completed`
- `item/completed`

This lines up much better with existing patterns (i.e. human review in
`Default mode`, where app-server would send a server request to prompt
for user approval after `item/started`), and makes it easier for clients
to render what guardian is actually reviewing.

We do this following a similar pattern as `FileChange` (aka apply patch)
items, where we create a FileChange item and emit `item/started` if we
see the apply patch approval request, before the actual apply patch call
runs.

  • feat(requirements): support allowed_approval_reviewers (#16701) 
    ## Description

Add requirements.toml support for `allowed_approvals_reviewers =
["user", "guardian_subagent"]`, so admins can now restrict the use of
guardian mode.

Note: If a user sets a reviewer that isn’t allowed by requirements.toml,
config loading falls back to the first allowed reviewer and emits a
startup warning.

The table below describes the possible admin controls.
| Admin intent | `requirements.toml` | User `config.toml` | End result |
|---|---|---|---|
| Leave Guardian optional | omit `allowed_approvals_reviewers` or set
`["user", "guardian_subagent"]` | user chooses `approvals_reviewer =
"user"` or `"guardian_subagent"` | Guardian off for `user`, on for
`guardian_subagent` + `approval_policy = "on-request"` |
| Force Guardian off | `allowed_approvals_reviewers = ["user"]` | any
user value | Effective reviewer is `user`; Guardian off |
| Force Guardian on | `allowed_approvals_reviewers =
["guardian_subagent"]` and usually `allowed_approval_policies =
["on-request"]` | any user reviewer value; user should also have
`approval_policy = "on-request"` unless policy is forced | Effective
reviewer is `guardian_subagent`; Guardian on when effective approval
policy is `on-request` |
| Allow both, but default to manual if user does nothing |
`allowed_approvals_reviewers = ["user", "guardian_subagent"]` | omit
`approvals_reviewer` | Effective reviewer is `user`; Guardian off |
| Allow both, and user explicitly opts into Guardian |
`allowed_approvals_reviewers = ["user", "guardian_subagent"]` |
`approvals_reviewer = "guardian_subagent"` and `approval_policy =
"on-request"` | Guardian on |
| Invalid admin config | `allowed_approvals_reviewers = []` | anything |

  • [codex-backend] Make thread metadata updates tolerate pending backfill (#16877) 
    ### Summary
Fix `thread/metadata/update` so it can still patch stored thread
metadata when the list/backfill-gated `get_state_db(...)` path is
unavailable.

What was happening:
- The app logs showed `thread/metadata/update` failing with `sqlite
state db unavailable for thread ...`.
- This was not isolated to one bad thread. Once the failure started for
a user, branch metadata updates failed 100% of the time for that user.
- Reports were staggered across users, which points at local app-server
/ local SQLite state rather than one global server-side failure.
- Turns could still start immediately after the metadata update failed,
which suggests the thread itself was valid and the failure was in the
metadata endpoint DB-handle path.

The fix:
- Keep using the loaded thread state DB and the normal
`get_state_db(...)` fallback first.
- If that still returns `None`, open `StateRuntime::init(...)` directly
for this targeted metadata update path.
- Log the direct state runtime init error if that final fallback also
fails, so future reports have the real DB-open cause instead of only the
generic unavailable error.
- Add a regression test where the DB exists but backfill is not
complete, and verify `thread/metadata/update` can still repair the
stored rollout thread and patch `gitInfo`.

Relevant context / suspect PRs:
- #16434 changed state DB startup to run auto-vacuum / incremental
vacuum. This is the most suspicious timing match for per-user, staggered
local SQLite availability failures.
- #16433 dropped the old log table from the state DB, also near the
timing window.
- #13280 introduced this endpoint and made it rely on SQLite for git
metadata without resuming the thread.
- #14859 and #14888 added/consumed persisted model + reasoning effort
metadata. I checked these because of the new thread metadata fields, but
this failure happens before the endpoint reaches thread-row update/load
logic, so they seem less likely as the direct cause.

### Testing
- `cargo fmt -- --config imports_granularity=Item` completed; local
stable rustfmt emitted warnings that `imports_granularity` is unstable
- `cargo test -p codex-app-server thread_metadata_update`
- `git diff --check`

  • Fix Windows Bazel app-server trust tests (#16711) 
    ## Why

Extracted from [#16528](https://github.com/openai/codex/pull/16528) so
the Windows Bazel app-server test failures can be reviewed independently
from the rest of that PR.

This PR targets:

-
`suite::v2::thread_shell_command::thread_shell_command_runs_as_standalone_turn_and_persists_history`
-
`suite::v2::thread_start::thread_start_with_elevated_sandbox_trusts_project_and_followup_loads_project_config`
-
`suite::v2::thread_start::thread_start_with_nested_git_cwd_trusts_repo_root`

There were two Windows-specific assumptions baked into those tests and
the underlying trust lookup:

- project trust keys were persisted and looked up using raw path
strings, but Bazel's Windows test environment can surface canonicalized
paths with `\\?\` / UNC prefixes or normalized symlink/junction targets,
so follow-up `thread/start` requests no longer matched the project entry
that had just been written
- `item/commandExecution/outputDelta` assertions compared exact trailing
line endings even though shell output chunk boundaries and CRLF handling
can differ on Windows, and Bazel made that timing-sensitive mismatch
visible

There was also one behavior bug separate from the assertion cleanup:
`thread/start` decided whether to persist trust from the final resolved
sandbox policy, but on Windows an explicit `workspace-write` request may
be downgraded to `read-only`. That incorrectly skipped writing trust
even though the request had asked to elevate the project, so the new
logic also keys off the requested sandbox mode.

## What

- Canonicalize project trust keys when persisting/loading `[projects]`
entries, while still accepting legacy raw keys for existing configs.
- Persist project trust when `thread/start` explicitly requests
`workspace-write` or `danger-full-access`, even if the resolved policy
is later downgraded on Windows.
- Make the Windows app-server tests compare persisted trust paths and
command output deltas in a path/newline-normalized way.

## Verification

- Existing app-server v2 tests cover the three failing Windows Bazel
cases above.

  • Add remote --cd forwarding for app-server sessions (#16700) 
    Addresses #16124

Problem: `codex --remote --cd <path>` canonicalized the path locally and
then omitted it from remote thread lifecycle requests, so remote-only
working directories failed or were ignored.

Solution: Keep remote startup on the local cwd, forward explicit `--cd`
values verbatim to `thread/start`, `thread/resume`, and `thread/fork`,
and cover the behavior with `codex-tui` tests.

Testing: I manually tested `--remote --cd` with both absolute and
relative paths and validated correct behavior.


---

Update based on code review feedback:

Problem: Remote `--cd` was forwarded to `thread/resume` and
`thread/fork`, but not to `thread/list` lookups, so `--resume --last`
and picker flows could select a session from the wrong cwd; relative cwd
filters also failed against stored absolute paths.

Solution: Apply explicit remote `--cd` to `thread/list` lookups for
`--last` and picker flows, normalize relative cwd filters on the
app-server before exact matching, and document/test the behavior.

  • Suppress bwrap warning when sandboxing is bypassed (#16667) 
    Addresses #15282

Problem: Codex warned about missing system bubblewrap even when
sandboxing was disabled.

Solution: Gate the bwrap warning on the active sandbox policy and skip
it for danger-full-access and external-sandbox modes.

  • Fix MCP tool listing for hyphenated server names (#16674) 
    Addresses #16671 and #14927

Problem: `mcpServerStatus/list` rebuilt MCP tool groups from sanitized
tool prefixes but looked them up by unsanitized server names, so
hyphenated servers rendered as having no tools in `/mcp`. This was
reported as a regression when the TUI switched to use the app server.

Solution: Build each server's tool map using the original server name's
sanitized prefix, include effective runtime MCP servers in the status
response, and add a regression test for hyphenated server names.

  • remove temporary ownership re-exports (#16626) 
    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.

  • extract models manager and related ownership from core (#16508) 
    ## Summary
- split `models-manager` out of `core` and add `ModelsManagerConfig`
plus `Config::to_models_manager_config()` so model metadata paths stop
depending on `core::Config`
- move login-owned/auth-owned code out of `core` into `codex-login`,
move model provider config into `codex-model-provider-info`, move API
bridge mapping into `codex-api`, move protocol-owned types/impls into
`codex-protocol`, and move response debug helpers into a dedicated
`response-debug-context` crate
- move feedback tag emission into `codex-feedback`, relocate tests to
the crates that now own the code, and keep broad temporary re-exports so
this PR avoids a giant import-only rewrite

## Major moves and decisions
- created `codex-models-manager` as the owner for model
cache/catalog/config/model info logic, including the new
`ModelsManagerConfig` struct
- created `codex-model-provider-info` as the owner for provider config
parsing/defaults and kept temporary `codex-login`/`codex-core`
re-exports for old import paths
- moved `api_bridge` error mapping + `CoreAuthProvider` into
`codex-api`, while `codex-login::api_bridge` temporarily re-exports
those symbols and keeps the `auth_provider_from_auth` wrapper
- moved `auth_env_telemetry` and `provider_auth` ownership to
`codex-login`
- moved `CodexErr` ownership to `codex-protocol::error`, plus
`StreamOutput`, `bytes_to_string_smart`, and network policy helpers to
protocol-owned modules
- created `codex-response-debug-context` for
`extract_response_debug_context`, `telemetry_transport_error_message`,
and related response-debug plumbing instead of leaving that behavior in
`core`
- moved `FeedbackRequestTags`, `emit_feedback_request_tags`, and
`emit_feedback_request_tags_with_auth_env` to `codex-feedback`
- deferred removal of temporary re-exports and the mechanical import
rewrites to a stacked follow-up PR so this PR stays reviewable

## Test moves
- moved auth refresh coverage from `core/tests/suite/auth_refresh.rs` to
`login/tests/suite/auth_refresh.rs`
- moved text encoding coverage from
`core/tests/suite/text_encoding_fix.rs` to
`protocol/src/exec_output_tests.rs`
- moved model info override coverage from
`core/tests/suite/model_info_overrides.rs` to
`models-manager/src/model_info_overrides_tests.rs`

  • Fix fork source display in /status (expose forked_from_id in app server) (#16596) 
    Addresses #16560

Problem: `/status` stopped showing the source thread id in forked TUI

Solution: Carry fork source ids through app-server v2 thread data and
the TUI session adapter, and update TUI fixtures so `/status` matches
the old TUI behavior.

  • [codex] Remove codex-core config type shim (#16529) 
    ## 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.

  • core: remove cross-crate re-exports from lib.rs (#16512) 
    ## 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`.

  • core: use codex-mcp APIs directly (#16510) 
    ## 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`.

  • Extract MCP into codex-mcp crate (#15919) 
    - Split MCP runtime/server code out of `codex-core` into the new
`codex-mcp` crate. New/moved public structs/types include `McpConfig`,
`McpConnectionManager`, `ToolInfo`, `ToolPluginProvenance`,
`CodexAppsToolsCacheKey`, and the `McpManager` API
(`codex_mcp::mcp::McpManager` plus the `codex_core::mcp::McpManager`
wrapper/shim). New/moved functions include `with_codex_apps_mcp`,
`configured_mcp_servers`, `effective_mcp_servers`,
`collect_mcp_snapshot`, `collect_mcp_snapshot_from_manager`,
`qualified_mcp_tool_name_prefix`, and the MCP auth/skill-dependency
helpers. Why: this creates a focused MCP crate boundary and shrinks
`codex-core` without forcing every consumer to migrate in the same PR.

- Move MCP server config schema and persistence into `codex-config`.
New/moved structs/enums include `AppToolApproval`,
`McpServerToolConfig`, `McpServerConfig`, `RawMcpServerConfig`,
`McpServerTransportConfig`, `McpServerDisabledReason`, and
`codex_config::ConfigEditsBuilder`. New/moved functions include
`load_global_mcp_servers` and
`ConfigEditsBuilder::replace_mcp_servers`/`apply`. Why: MCP TOML
parsing/editing is config ownership, and this keeps config
validation/round-tripping (including per-tool approval overrides and
inline bearer-token rejection) in the config crate instead of
`codex-core`.

- Rewire `codex-core`, app-server, and plugin call sites onto the new
crates. Updated `Config::to_mcp_config(&self, plugins_manager)`,
`codex-rs/core/src/mcp.rs`, `codex-rs/core/src/connectors.rs`,
`codex-rs/core/src/codex.rs`,
`CodexMessageProcessor::list_mcp_server_status_task`, and
`utils/plugins/src/mcp_connector.rs` to build/pass the new MCP
config/runtime types. Why: plugin-provided MCP servers still merge with
user-configured servers, and runtime auth (`CodexAuth`) is threaded into
`with_codex_apps_mcp` / `collect_mcp_snapshot` explicitly so `McpConfig`
stays config-only.

  • fix(guardian): make GuardianAssessmentEvent.action strongly typed (#16448) 
    ## Description

Previously the `action` field on `EventMsg::GuardianAssessment`, which
describes what Guardian is reviewing, was typed as an arbitrary JSON
blob. This PR cleans it up and defines a sum type representing all the
various actions that Guardian can review.

This is a breaking change (on purpose), which is fine because:
- the Codex app / VSCE does not actually use `action` at the moment
- the TUI code that consumes `action` is updated in this PR as well
- rollout files that serialized old `EventMsg::GuardianAssessment` will
just silently drop these guardian events
- the contract is defined as unstable, so other clients have a fair
warning :)

This will make things much easier for followup Guardian work.

## Why

The old guardian review payloads worked, but they pushed too much shape
knowledge into downstream consumers. The TUI had custom JSON parsing
logic for commands, patches, network requests, and MCP calls, and the
app-server protocol was effectively just passing through an opaque blob.

Typing this at the protocol boundary makes the contract clearer.

  • auth: let AuthManager own external bearer auth (#16287) 
    ## Summary

`AuthManager` and `UnauthorizedRecovery` already own token resolution
and staged `401` recovery. The missing piece for provider auth was a
bearer-only mode that still fit that design, instead of pushing a second
auth abstraction into `codex-core`.

This PR keeps the design centered on `AuthManager`: it teaches
`codex-login` how to own external bearer auth directly so later provider
work can keep calling `AuthManager.auth()` and `UnauthorizedRecovery`.

## Motivation

This is the middle layer for #15189.

The intended design is still:

- `AuthManager` encapsulates token storage and refresh
- `UnauthorizedRecovery` powers staged `401` recovery
- all request tokens go through `AuthManager.auth()`

This PR makes that possible for provider-backed bearer tokens by adding
a bearer-only auth mode inside `AuthManager` instead of building
parallel request-auth plumbing in `core`.

## What Changed

- move `ModelProviderAuthInfo` into `codex-protocol` so `core` and
`login` share one config shape
- add `login/src/auth/external_bearer.rs`, which runs the configured
command, caches the bearer token in memory, and refreshes it after `401`
- add `AuthManager::external_bearer_only(...)` for provider-scoped
request paths that should use command-backed bearer auth without
mutating the shared OpenAI auth manager
- add `AuthManager::shared_with_external_chatgpt_auth_refresher(...)`
and rename the other `AuthManager` helpers that only apply to external
ChatGPT auth so the ChatGPT-only path is explicit at the call site
- keep external ChatGPT refresh behavior unchanged while ensuring
bearer-only external auth never persists to `auth.json`

## Testing

- `cargo test -p codex-login`
- `cargo test -p codex-protocol`

  • auth: generalize external auth tokens for bearer-only sources (#16286) 
    ## Summary

`ExternalAuthRefresher` was still shaped around external ChatGPT auth:
`ExternalAuthTokens` always implied ChatGPT account metadata even when a
caller only needed a bearer token.

This PR generalizes that contract so bearer-only sources are
first-class, while keeping the existing ChatGPT paths strict anywhere we
persist or rebuild ChatGPT auth state.

## Motivation

This is the first step toward #15189.

The follow-on provider-auth work needs one shared external-auth contract
that can do both of these things:

- resolve the current bearer token before a request is sent
- return a refreshed bearer token after a `401`

That should not require a second token result type just because there is
no ChatGPT account metadata attached.

## What Changed

- change `ExternalAuthTokens` to carry `access_token` plus optional
`ExternalAuthChatgptMetadata`
- add helper constructors for bearer-only tokens and ChatGPT-backed
tokens
- add `ExternalAuthRefresher::resolve()` with a default no-op
implementation so refreshers can optionally provide the current token
before a request is sent
- keep ChatGPT-only persistence strict by continuing to require ChatGPT
metadata anywhere the login layer seeds or reloads ChatGPT auth state
- update the app-server bridge to construct the new token shape for
external ChatGPT auth refreshes

## Testing

- `cargo test -p codex-login`

  • chore: clean up argument-comment lint and roll out all-target CI on macOS (#16054) 
    ## 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.

the `tui_app_server` feature flag in place for now so its presence

Part 2 will rename the `tui_app_server` directory `tui`. I did this as

  • Add ChatGPT device-code login to app server (#15525) 
    ## Problem

App-server clients could only initiate ChatGPT login through the browser
callback flow, even though the shared login crate already supports
device-code auth. That left VS Code, Codex App, and other app-server
clients without a first-class way to use the existing device-code
backend when browser redirects are brittle or when the client UX wants
to own the login ceremony.

## Mental model

This change adds a second ChatGPT login start path to app-server:
clients can now call `account/login/start` with `type:
"chatgptDeviceCode"`. App-server immediately returns a `loginId` plus
the device-code UX payload (`verificationUrl` and `userCode`), then
completes the login asynchronously in the background using the existing
`codex_login` polling flow. Successful device-code login still resolves
to ordinary `chatgpt` auth, and completion continues to flow through the
existing `account/login/completed` and `account/updated` notifications.

## Non-goals

This does not introduce a new auth mode, a new account shape, or a
device-code eligibility discovery API. It also does not add automatic
fallback to browser login in core; clients remain responsible for
choosing when to request device code and whether to retry with a
different UX if the backend/admin policy rejects it.

## Tradeoffs

We intentionally keep `login_chatgpt_common` as a local validation
helper instead of turning it into a capability probe. Device-code
eligibility is checked by actually calling `request_device_code`, which
means policy-disabled cases surface as an immediate request error rather
than an async completion event. We also keep the active-login state
machine minimal: browser and device-code logins share the same public
cancel contract, but device-code cancellation is implemented with a
local cancel token rather than a larger cross-crate refactor.

## Architecture

The protocol grows a new `chatgptDeviceCode` request/response variant in
app-server v2. On the server side, the new handler reuses the existing
ChatGPT login precondition checks, calls `request_device_code`, returns
the device-code payload, and then spawns a background task that waits on
either cancellation or `complete_device_code_login`. On success, it
reuses the existing auth reload and cloud-requirements refresh path
before emitting `account/login/completed` success and `account/updated`.
On failure or cancellation, it emits only `account/login/completed`
failure. The existing `account/login/cancel { loginId }` contract
remains unchanged and now works for both browser and device-code
attempts.


## Tests

Added protocol serialization coverage for the new request/response
variant, plus app-server tests for device-code success, failure, cancel,
and start-time rejection behavior. Existing browser ChatGPT login
coverage remains in place to show that the callback-based flow is
unchanged.

  • chore: refactor network permissions to use explicit domain and unix socket rule maps (#15120) 
    ## Summary

This PR replaces the legacy network allow/deny list model with explicit
rule maps for domains and unix sockets across managed requirements,
permissions profiles, the network proxy config, and the app server
protocol.

Concretely, it:

- introduces typed domain (`allow` / `deny`) and unix socket permission
(`allow` / `none`) entries instead of separate `allowed_domains`,
`denied_domains`, and `allow_unix_sockets` lists
- updates config loading, managed requirements merging, and exec-policy
overlays to read and upsert rule entries consistently
- exposes the new shape through protocol/schema outputs, debug surfaces,
and app-server config APIs
- rejects the legacy list-based keys and updates docs/tests to reflect
the new config format

## Why

The previous representation split related network policy across multiple
parallel lists, which made merging and overriding rules harder to reason
about. Moving to explicit keyed permission maps gives us a single source
of truth per host/socket entry, makes allow/deny precedence clearer, and
gives protocol consumers access to the full rule state instead of
derived projections only.

## Backward Compatibility

### Backward compatible

- Managed requirements still accept the legacy
`experimental_network.allowed_domains`,
`experimental_network.denied_domains`, and
`experimental_network.allow_unix_sockets` fields. They are normalized
into the new canonical `domains` and `unix_sockets` maps internally.
- App-server v2 still deserializes legacy `allowedDomains`,
`deniedDomains`, and `allowUnixSockets` payloads, so older clients can
continue reading managed network requirements.
- App-server v2 responses still populate `allowedDomains`,
`deniedDomains`, and `allowUnixSockets` as legacy compatibility views
derived from the canonical maps.
- `managed_allowed_domains_only` keeps the same behavior after
normalization. Legacy managed allowlists still participate in the same
enforcement path as canonical `domains` entries.

### Not backward compatible

- Permissions profiles under `[permissions.<profile>.network]` no longer
accept the legacy list-based keys. Those configs must use the canonical
`[domains]` and `[unix_sockets]` tables instead of `allowed_domains`,
`denied_domains`, or `allow_unix_sockets`.
- Managed `experimental_network` config cannot mix canonical and legacy
forms in the same block. For example, `domains` cannot be combined with
`allowed_domains` or `denied_domains`, and `unix_sockets` cannot be
combined with `allow_unix_sockets`.
- The canonical format can express explicit `"none"` entries for unix
sockets, but those entries do not round-trip through the legacy
compatibility fields because the legacy fields only represent allow/deny
lists.
## Testing
`/target/debug/codex sandbox macos --log-denials /bin/zsh -c 'curl
https://www.example.com' ` gives 200 with config
```
[permissions.workspace.network.domains]
"www.example.com" = "allow"
```
and fails when set to deny: `curl: (56) CONNECT tunnel failed, response
403`.

Also tested backward compatibility path by verifying that adding the
following to `/etc/codex/requirements.toml` works:
```
[experimental_network]
allowed_domains = ["www.example.com"]
```

  • permissions: remove macOS seatbelt extension profiles (#15918) 
    ## 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.

  • codex-tools: extract shared tool schema parsing (#15923) 
    ## Why

`parse_tool_input_schema` and the supporting `JsonSchema` model were
living in `core/src/tools/spec.rs`, but they already serve callers
outside `codex-core`.

Keeping that shared schema parsing logic inside `codex-core` makes the
crate boundary harder to reason about and works against the guidance in
`AGENTS.md` to avoid growing `codex-core` when reusable code can live
elsewhere.

This change takes the first extraction step by moving the schema parsing
primitive into its own crate while keeping the rest of the tool-spec
assembly in `codex-core`.

## What changed

- added a new `codex-tools` crate under `codex-rs/tools`
- moved the shared tool input schema model and sanitizer/parser into
`tools/src/json_schema.rs`
- kept `tools/src/lib.rs` exports-only, with the module-level unit tests
split into `json_schema_tests.rs`
- updated `codex-core` to use `codex-tools::JsonSchema` and re-export
`parse_tool_input_schema`
- updated `codex-app-server` dynamic tool validation to depend on
`codex-tools` directly instead of reaching through `codex-core`
- wired the new crate into the Cargo workspace and Bazel build graph

  • chore: remove skill metadata from command approval payloads (#15906) 
    ## Why

This is effectively a follow-up to
[#15812](https://github.com/openai/codex/pull/15812). That change
removed the special skill-script exec path, but `skill_metadata` was
still being threaded through command-approval payloads even though the
approval flow no longer uses it to render prompts or resolve decisions.

Keeping it around added extra protocol, schema, and client surface area
without changing behavior.

Removing it keeps the command-approval contract smaller and avoids
carrying a dead field through app-server, TUI, and MCP boundaries.

## What changed

- removed `ExecApprovalRequestSkillMetadata` and the corresponding
`skillMetadata` field from core approval events and the v2 app-server
protocol
- removed the generated JSON and TypeScript schema output for that field
- updated app-server, MCP server, TUI, and TUI app-server approval
plumbing to stop forwarding the field
- cleaned up tests that previously constructed or asserted
`skillMetadata`

## Testing

- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-test-client`
- `cargo test -p codex-mcp-server`

  • fix: fix old system bubblewrap compatibility without falling back to vendored bwrap (#15693) 
    Fixes #15283.

## Summary
Older system bubblewrap builds reject `--argv0`, which makes our Linux
sandbox fail before the helper can re-exec. This PR keeps using system
`/usr/bin/bwrap` whenever it exists and only falls back to vendored
bwrap when the system binary is missing. That matters on stricter
AppArmor hosts, where the distro bwrap package also provides the policy
setup needed for user namespaces.

For old system bwrap, we avoid `--argv0` instead of switching binaries:
- pass the sandbox helper a full-path `argv0`,
- keep the existing `current_exe() + --argv0` path when the selected
launcher supports it,
- otherwise omit `--argv0` and re-exec through the helper's own
`argv[0]` path, whose basename still dispatches as
`codex-linux-sandbox`.

Also updates the launcher/warning tests and docs so they match the new
behavior: present-but-old system bwrap uses the compatibility path, and
only absent system bwrap falls back to vendored.

### Validation

1. Install Ubuntu 20.04 in a VM
2. Compile codex and run without bubblewrap installed - see a warning
about falling back to the vendored bwrap
3. Install bwrap and verify version is 0.4.0 without `argv0` support
4. run codex and use apply_patch tool without errors

  • Avoid duplicate auth refreshes in getAuthStatus (#15798) 
    I've seen several intermittent failures of
`get_auth_status_returns_token_after_proactive_refresh_recovery` today.
I investigated, and I found a couple of issues.

First, `getAuthStatus(refreshToken=true)` could refresh twice in one
request: once via `refresh_token_if_requested()` and again via the
proactive refresh path inside `auth_manager.auth()`. In the
permanent-failure case this produced an extra `/oauth/token` call and
made the app-server auth tests flaky. Use `auth_cached()` after an
explicit refresh request so the handler reuses the post-refresh auth
state instead of immediately re-entering proactive refresh logic. Keep
the existing proactive path for `refreshToken=false`.

Second, serialize auth refresh attempts in `AuthManager` have a
startup/request race. One proactive refresh could already be in flight
while a `getAuthStatus(refreshToken=false)` request entered
`auth().await`, causing a second `/oauth/token` call before the first
failure or refresh result had been recorded. Guarding the refresh flow
with a single async lock makes concurrent callers share one refresh
result, which prevents duplicate refreshes and stabilizes the
proactive-refresh auth tests.

  • feat: add websocket auth for app-server (#14847) 
    ## 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.

  • Use AbsolutePathBuf for cwd state (#15710) 
    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.

  • fix: support split carveouts in windows restricted-token sandbox (#14172) 
    ## Summary
- keep legacy Windows restricted-token sandboxing as the supported
baseline
- support the split-policy subset that restricted-token can enforce
directly today
- support full-disk read, the same writable root set as legacy
`WorkspaceWrite`, and extra read-only carveouts under those writable
roots via additional deny-write ACLs
- continue to fail closed for unsupported split-only shapes, including
explicit unreadable (`none`) carveouts, reopened writable descendants
under read-only carveouts, and writable root sets that do not match the
legacy workspace roots

## Example
Given a filesystem policy like:

```toml
":root" = "read"
":cwd" = "write"
"./docs" = "read"
```

the restricted-token backend can keep the workspace writable while
denying writes under `docs` by layering an extra deny-write carveout on
top of the legacy workspace-write roots.

A policy like:

```toml
"/workspace" = "write"
"/workspace/docs" = "read"
"/workspace/docs/tmp" = "write"
```

still fails closed, because the unelevated backend cannot reopen the
nested writable descendant safely.

  • app-server: add filesystem watch support (#14533) 
    ### Summary
Add the v2 app-server filesystem watch RPCs and notifications, wire them
through the message processor, and implement connection-scoped watches
with notify-backed change delivery. This also updates the schema
fixtures, app-server documentation, and the v2 integration coverage for
watch and unwatch behavior.

This allows clients to efficiently watch for filesystem updates, e.g. to
react on branch changes.

### Testing
- exercise watch lifecycles for directory changes, atomic file
replacement, missing-file targets, and unwatch cleanup

  • Drop sandbox_permissions from sandbox exec requests (#15665) 
    ## Summary
- drop `sandbox_permissions` from the sandboxing `ExecOptions` and
`ExecRequest` adapter types
- remove the now-unused plumbing from shell, unified exec, JS REPL, and
apply-patch runtime call sites
- default reconstructed `ExecParams` to `SandboxPermissions::UseDefault`
where the lower-level API still requires the field

## Testing
- `just fmt`
- `just argument-comment-lint`
- `cargo test -p codex-core` (still running locally; first failures
observed in `suite::cli_stream::responses_mode_stream_cli`,
`suite::cli_stream::responses_mode_stream_cli_supports_openai_base_url_config_override`,
and
`suite::cli_stream::responses_mode_stream_cli_supports_openai_base_url_env_fallback`)
