• feat: make sandbox read access configurable with ReadOnlyAccess (#11387)

  `SandboxPolicy::ReadOnly` previously implied broad read access and could
  not express a narrower read surface.
  This change introduces an explicit read-access model so we can support
  user-configurable read restrictions in follow-up work, while preserving
  current behavior today.
  
  It also ensures unsupported backends fail closed for restricted-read
  policies instead of silently granting broader access than intended.
  
  ## What
  
  - Added `ReadOnlyAccess` in protocol with:
    - `Restricted { include_platform_defaults, readable_roots }`
    - `FullAccess`
  - Updated `SandboxPolicy` to carry read-access configuration:
    - `ReadOnly { access: ReadOnlyAccess }`
    - `WorkspaceWrite { ..., read_only_access: ReadOnlyAccess }`
  - Preserved existing behavior by defaulting current construction paths
  to `ReadOnlyAccess::FullAccess`.
  - Threaded the new fields through sandbox policy consumers and call
  sites across `core`, `tui`, `linux-sandbox`, `windows-sandbox`, and
  related tests.
  - Updated Seatbelt policy generation to honor restricted read roots by
  emitting scoped read rules when full read access is not granted.
  - Added fail-closed behavior on Linux and Windows backends when
  restricted read access is requested but not yet implemented there
  (`UnsupportedOperation`).
  - Regenerated app-server protocol schema and TypeScript artifacts,
  including `ReadOnlyAccess`.
  
  ## Compatibility / rollout
  
  - Runtime behavior remains unchanged by default (`FullAccess`).
  - API/schema changes are in place so future config wiring can enable
  restricted read access without another policy-shape migration.

• test(app-server): stabilize app/list thread feature-flag test by using file-backed MCP OAuth creds (#11521)

  ## Why
  
  `suite::v2::app_list::list_apps_uses_thread_feature_flag_when_thread_id_is_provided`
  has been flaky in CI. The test exercises `thread/start`, which
  initializes `codex_apps`. In CI/Linux, that path can reach OS
  keyring-backed MCP OAuth credential lookup (`Codex MCP Credentials`) and
  intermittently abort the MCP process (observed stack overflow in
  `zbus`), causing the test to fail before the assertion logic runs.
  
  ## What Changed
  
  - Updated the test config in
  `codex-rs/app-server/tests/suite/v2/app_list.rs` to set
  `mcp_oauth_credentials_store = "file"` in both relevant config-writing
  paths:
  - The in-test config override inside
  `list_apps_uses_thread_feature_flag_when_thread_id_is_provided`
  - `write_connectors_config(...)`, which is used by the v2 `app_list`
  test suite
  - This keeps test coverage focused on thread-scoped app feature flags
  while removing OS keyring/DBus dependency from this test path.
  
  ## How It Was Verified
  
  - `cargo test -p codex-app-server`
  - `cargo test -p codex-app-server
  list_apps_uses_thread_feature_flag_when_thread_id_is_provided --
  --nocapture`

• app-server: thread resume subscriptions (#11474)

  This stack layer makes app-server thread event delivery connection-aware
  so resumed/attached threads only emit notifications and approval prompts
  to subscribed connections.
  
  - Added per-thread subscription tracking in `ThreadState`
  (`subscribed_connections`) and mapped subscription ids to `(thread_id,
  connection_id)`.
  - Updated listener lifecycle so removing a subscription or closing a
  connection only removes that connection from the thread’s subscriber
  set; listener shutdown now happens when the last subscriber is gone.
  - Added `connection_closed(connection_id)` plumbing (`lib.rs` ->
  `message_processor.rs` -> `codex_message_processor.rs`) so disconnect
  cleanup happens immediately.
  - Scoped bespoke event handling outputs through `TargetedOutgoing` to
  send requests/notifications only to subscribed connections.
  - Kept existing threadresume behavior while aligning with the latest
  split-loop transport structure.

• Reapply "Add app-server transport layer with websocket support" (#11370)

  Reapply "Add app-server transport layer with websocket support" with
  additional fixes from https://github.com/openai/codex/pull/11313/changes
  to avoid deadlocking.
  
  This reverts commit 47356ff83c.
  
  ## Summary
  
  To avoid deadlocking when queues are full, we maintain separate tokio
  tasks dedicated to incoming vs outgoing event handling
  - split the app-server main loop into two tasks in
  `run_main_with_transport`
     - inbound handling (`transport_event_rx`)
     - outbound handling (`outgoing_rx` + `thread_created_rx`)
  - separate incoming and outgoing websocket tasks
  
  ## Validation
  
  Integration tests, testing thoroughly e2e in codex app w/ >10 concurrent
  requests

• Cache cloud requirements (#11305)

  We're loading these from the web on every startup. This puts them in a
  local file with a 1hr TTL.
  
  We sign the downloaded requirements with a key compiled into the Codex
  CLI to prevent unsophisticated tampering (determined circumvention is
  outside of our threat model: after all, one could just compile Codex
  without any of these checks).
  
  If any of the following are true, we ignore the local cache and re-fetch
  from Cloud:
  * The signature is invalid for the payload (== requirements, sign time,
  ttl, user identity)
  * The identity does not match the auth'd user's identity
  * The TTL has expired
  * We cannot parse requirements.toml from the payload

• feat: split codex-common into smaller utils crates (#11422)

  We are removing feature-gated shared crates from the `codex-rs`
  workspace. `codex-common` grouped several unrelated utilities behind
  `[features]`, which made dependency boundaries harder to reason about
  and worked against the ongoing effort to eliminate feature flags from
  workspace crates.
  
  Splitting these utilities into dedicated crates under `utils/` aligns
  this area with existing workspace structure and keeps each dependency
  explicit at the crate boundary.
  
  ## What changed
  
  - Removed `codex-rs/common` (`codex-common`) from workspace members and
  workspace dependencies.
  - Added six new utility crates under `codex-rs/utils/`:
    - `codex-utils-cli`
    - `codex-utils-elapsed`
    - `codex-utils-sandbox-summary`
    - `codex-utils-approval-presets`
    - `codex-utils-oss`
    - `codex-utils-fuzzy-match`
  - Migrated the corresponding modules out of `codex-common` into these
  crates (with tests), and added matching `BUILD.bazel` targets.
  - Updated direct consumers to use the new crates instead of
  `codex-common`:
    - `codex-rs/cli`
    - `codex-rs/tui`
    - `codex-rs/exec`
    - `codex-rs/app-server`
    - `codex-rs/mcp-server`
    - `codex-rs/chatgpt`
    - `codex-rs/cloud-tasks`
  - Updated workspace lockfile entries to reflect the new dependency graph
  and removal of `codex-common`.

• Remove test-support feature from codex-core and replace it with explicit test toggles (#11405)

  ## Why
  
  `codex-core` was being built in multiple feature-resolved permutations
  because test-only behavior was modeled as crate features. For a large
  crate, those permutations increase compile cost and reduce cache reuse.
  
  ## Net Change
  
  - Removed the `test-support` crate feature and related feature wiring so
  `codex-core` no longer needs separate feature shapes for test consumers.
  - Standardized cross-crate test-only access behind
  `codex_core::test_support`.
  - External test code now imports helpers from
  `codex_core::test_support`.
  - Underlying implementation hooks are kept internal (`pub(crate)`)
  instead of broadly public.
  
  ## Outcome
  
  - Fewer `codex-core` build permutations.
  - Better incremental cache reuse across test targets.
  - No intended production behavior change.

• chore: persist turn_id in rollout session and make turn_id uuid based (#11246)

  Problem:
  1. turn id is constructed in-memory;
  2. on resuming threads, turn_id might not be unique;
  3. client cannot no the boundary of a turn from rollout files easily.
  
  This PR does three things:
  1. persist `task_started` and `task_complete` events;
  1. persist `turn_id` in rollout turn events;
  5. generate turn_id as unique uuids instead of incrementing it in
  memory.
  
  This helps us resolve the issue of clients wanting to have unique turn
  ids for resuming a thread, and knowing the boundry of each turn in
  rollout files.
  
  example debug logs
  ```
  2026-02-11T00:32:10.746876Z DEBUG codex_app_server_protocol::protocol::thread_history: built turn from rollout items turn_index=8 turn=Turn { id: "019c4a07-d809-74c3-bc4b-fd9618487b4b", items: [UserMessage { id: "item-24", content: [Text { text: "hi", text_elements: [] }] }, AgentMessage { id: "item-25", text: "Hi. I’m in the workspace with your current changes loaded and ready. Send the next task and I’ll execute it end-to-end." }], status: Completed, error: None }
  2026-02-11T00:32:10.746888Z DEBUG codex_app_server_protocol::protocol::thread_history: built turn from rollout items turn_index=9 turn=Turn { id: "019c4a18-1004-76c0-a0fb-a77610f6a9b8", items: [UserMessage { id: "item-26", content: [Text { text: "hello", text_elements: [] }] }, AgentMessage { id: "item-27", text: "Hello. Ready for the next change in `codex-rs`; I can continue from the current in-progress diff or start a new task." }], status: Completed, error: None }
  2026-02-11T00:32:10.746899Z DEBUG codex_app_server_protocol::protocol::thread_history: built turn from rollout items turn_index=10 turn=Turn { id: "019c4a19-41f0-7db0-ad78-74f1503baeb8", items: [UserMessage { id: "item-28", content: [Text { text: "hello", text_elements: [] }] }, AgentMessage { id: "item-29", text: "Hello. Send the specific change you want in `codex-rs`, and I’ll implement it and run the required checks." }], status: Completed, error: None }
  ```
  
  backward compatibility:
  if you try to resume an old session without task_started and
  task_complete event populated, the following happens:
  - If you resume and do nothing: those reconstructed historical IDs can
  differ next time you resume.
  - If you resume and send a new turn: the new turn gets a fresh UUID from
  live submission flow and is persisted, so that new turn’s ID is stable
  on later resumes.
  I think this behavior is fine, because we only care about deterministic
  turn id once a turn is triggered.

• feat: retain NetworkProxy, when appropriate (#11207)

  As of this PR, `SessionServices` retains a
  `Option<StartedNetworkProxy>`, if appropriate.
  
  Now the `network` field on `Config` is `Option<NetworkProxySpec>`
  instead of `Option<NetworkProxy>`.
  
  Over in `Session::new()`, we invoke `NetworkProxySpec::start_proxy()` to
  create the `StartedNetworkProxy`, which is a new struct that retains the
  `NetworkProxy` as well as the `NetworkProxyHandle`. (Note that `Drop` is
  implemented for `NetworkProxyHandle` to ensure the proxies are shutdown
  when it is dropped.)
  
  The `NetworkProxy` from the `StartedNetworkProxy` is threaded through to
  the appropriate places.

• fix(app-server): for external auth, replace id_token with chatgpt_acc… (#11240)

  …ount_id and chatgpt_plan_type
  
  ### Summary
  Following up on external auth mode which was introduced here:
  https://github.com/openai/codex/pull/10012
  
  Turns out some clients have a differently shaped ID token and don't have
  a chosen workspace (aka chatgpt_account_id) encoded in their ID token.
  So, let's replace `id_token` param with `chatgpt_account_id` and
  `chatgpt_plan_type` (optional) when initializing the external ChatGPT
  auth mode (`account/login/start` with `chatgptAuthTokens`).
  
  The client was able to test end-to-end with a Codex build from this
  branch and verified it worked!

• [apps] Improve app loading. (#10994)

  There are two concepts of apps that we load in the harness:
  
  - Directory apps, which is all the apps that the user can install.
  - Accessible apps, which is what the user actually installed and can be
  $ inserted and be used by the model. These are extracted from the tools
  that are loaded through the gateway MCP.
  
  Previously we wait for both sets of apps before returning the full apps
  list. Which causes many issues because accessible apps won't be
  available to the UI or the model if directory apps aren't loaded or
  failed to load.
  
  In this PR we are separating them so that accessible apps can be loaded
  separately and are instantly available to be shown in the UI and to be
  provided in model context. We also added an app-server event so that
  clients can subscribe to also get accessible apps without being blocked
  on the full app list.
  
  - [x] Separate accessible apps and directory apps loading.
  - [x] `app/list` request will also emit `app/list/updated` notifications
  that app-server clients can subscribe. Which allows clients to get
  accessible apps list to render in the $ menu without being blocked by
  directory apps.
  - [x] Cache both accessible and directory apps with 1 hour TTL to avoid
  reloading them when creating new threads.
  - [x] TUI improvements to redraw $ menu and /apps menu when app list is
  updated.

• Defer persistence of rollout file (#11028)

  - Defer rollout persistence for fresh threads (`InitialHistory::New`):
  keep rollout events in memory and only materialize rollout file + state
  DB row on first `EventMsg::UserMessage`.
  - Keep precomputed rollout path available before materialization.
  - Change `thread/start` to build thread response from live config
  snapshot and optional precomputed path.
  - Improve pre-materialization behavior in app-server/TUI: clearer
  invalid-request errors for file-backed ops and a friendlier `/fork` “not
  ready yet” UX.
  - Update tests to match deferred semantics across
  start/read/archive/unarchive/fork/resume/review flows.
  - Improved resilience of user_shell test, which should be unrelated to
  this change but must be affected by timing changes
  
  For Reviewers:
  * The primary change is in recorder.rs
  * Most of the other changes were to fix up broken assumptions in
  existing tests
  
  Testing:
  * Manually tested CLI
  * Exercised app server paths by manually running IDE Extension with
  rebuilt CLI binary
  * Only user-visible change is that `/fork` in TUI generates visible
  error if used prior to first turn

• app-server: treat null mode developer instructions as built-in defaults (#10983)

  ## Summary
  - make `turn/start` normalize
  `collaborationMode.settings.developer_instructions: null` to the
  built-in instructions for the selected mode
  - prevent app-server clients from accidentally clearing mode-switch
  developer instructions by sending `null`
  - document this behavior in the v2 protocol and app-server docs
  
  ## What changed
  - `codex-rs/app-server/src/codex_message_processor.rs`
    - added a small `normalize_turn_start_collaboration_mode` helper
    - in `turn_start`, apply normalization before `OverrideTurnContext`
  - `codex-rs/app-server/tests/suite/v2/turn_start.rs`
  - extended `turn_start_accepts_collaboration_mode_override_v2` to assert
  the outgoing request includes default-mode instruction text when the
  client sends `developer_instructions: null`
  - `codex-rs/app-server-protocol/src/protocol/v2.rs`
  - clarified `TurnStartParams.collaboration_mode` docs:
  `settings.developer_instructions: null` means use built-in mode
  instructions
  - regenerated schema fixture:
  - `codex-rs/app-server-protocol/schema/typescript/v2/TurnStartParams.ts`
  - docs:
    - `codex-rs/app-server/README.md`
    - `codex-rs/docs/codex_mcp_interface.md`

• feat: add support for allowed_web_search_modes in requirements.toml (#10964)

  This PR makes it possible to disable live web search via an enterprise
  config even if the user is running in `--yolo` mode (though cached web
  search will still be available). To do this, create
  `/etc/codex/requirements.toml` as follows:
  
  ```toml
  # "live" is not allowed; "disabled" is allowed even though not listed explicitly.
  allowed_web_search_modes = ["cached"]
  ```
  
  Or set `requirements_toml_base64` MDM as explained on
  https://developers.openai.com/codex/security/#locations.
  
  ### Why
  - Enforce admin/MDM/`requirements.toml` constraints on web-search
  behavior, independent of user config and per-turn sandbox defaults.
  - Ensure per-turn config resolution and review-mode overrides never
  crash when constraints are present.
  
  ### What
  - Add `allowed_web_search_modes` to requirements parsing and surface it
  in app-server v2 `ConfigRequirements` (`allowedWebSearchModes`), with
  fixtures updated.
  - Define a requirements allowlist type (`WebSearchModeRequirement`) and
  normalize semantics:
    - `disabled` is always implicitly allowed (even if not listed).
    - An empty list is treated as `["disabled"]`.
  - Make `Config.web_search_mode` a `Constrained<WebSearchMode>` and apply
  requirements via `ConstrainedWithSource<WebSearchMode>`.
  - Update per-turn resolution (`resolve_web_search_mode_for_turn`) to:
  - Prefer `Live → Cached → Disabled` when
  `SandboxPolicy::DangerFullAccess` is active (subject to requirements),
  unless the user preference is explicitly `Disabled`.
  - Otherwise, honor the user’s preferred mode, falling back to an allowed
  mode when necessary.
  - Update TUI `/debug-config` and app-server mapping to display
  normalized `allowed_web_search_modes` (including implicit `disabled`).
  - Fix web-search integration tests to assert cached behavior under
  `SandboxPolicy::ReadOnly` (since `DangerFullAccess` legitimately prefers
  `live` when allowed).

• Fixed a flaky test (#10970)

  ## Summary
  
  Stabilize v2 review integration tests by making them hermetic with
  respect to model discovery.
  
  `app-server` review tests were intermittently timing out in CI
  (especially on Windows runners) because their test config allowed remote
  model refresh. During `thread/start`, the test process could issue live
  `/v1/models` requests, introducing external network latency and
  nondeterministic timing before review flow assertions.
  
  This change disables remote model fetching in the review test config
  helper used by these tests.

• Handle required MCP startup failures across components (#10902)

  Summary
  - add a `required` flag for MCP servers everywhere config/CLI data is
  touched so mandatory helpers can be round-tripped
  - have `codex exec` and `codex app-server` thread start/resume fail fast
  when required MCPs fail to initialize

• feat(app-server): turn/steer API (#10821)

  This PR adds a dedicated `turn/steer` API for appending user input to an
  in-flight turn.
  
  ## Motivation
  Currently, steering in the app is implemented by just calling
  `turn/start` while a turn is running. This has some really weird quirks:
  - Client gets back a new `turn.id`, even though streamed
  events/approvals remained tied to the original active turn ID.
  - All the various turn-level override params on `turn/start` do not
  apply to the "steer", and would only apply to the next real turn.
  - There can also be a race condition where the client thinks the turn is
  active but the server has already completed it, so there might be bugs
  if the client has baked in some client-specific behavior thinking it's a
  steer when in fact the server kicked off a new turn. This is
  particularly possible when running a client against a remote app-server.
  
  Having a dedicated `turn/steer` API eliminates all those quirks.
  
  `turn/steer` behavior:
  - Requires an active turn on threadId. Returns a JSON-RPC error if there
  is no active turn.
  - If expectedTurnId is provided, it must match the active turn (more
  useful when connecting to a remote app-server).
  - Does not emit `turn/started`.
  - Does not accept turn overrides (`cwd`, `model`, `sandbox`, etc.) or
  `outputSchema` to accurately reflect that these are not applied when
  steering.

• Add app-server transport layer with websocket support (#10693)

  - Adds --listen <URL> to codex app-server with two listen modes:
        - stdio:// (default, existing behavior)
        - ws://IP:PORT (new websocket transport)
    - Refactors message routing to be connection-aware:
  - Tracks per-connection session state (initialize/experimental
  capability)
        - Routes responses/errors to the originating connection
  - Broadcasts server notifications/requests to initialized connections
  - Updates initialization semantics to be per connection (not
  process-global), and updates app-server docs accordingly.
  - Adds websocket accept/read/write handling (JSON-RPC per text frame,
  ping/pong handling, connection lifecycle events).
  
  Testing
  
  - Unit tests for transport URL parsing and targeted response/error
  routing.
    - New websocket integration test validating:
        - per-connection initialization requirements
        - no cross-connection response leakage
        - same request IDs on different connections route independently.

• Leverage state DB metadata for thread summaries (#10621)

  Summary:
  - read conversation summaries and cwd info from the state DB when
  possible so we no longer rely on rollout files for metadata and avoid
  extra I/O
  - persist CLI version in thread metadata, surface it through summary
  builders, and add the necessary DB migration hooks
  - simplify thread listing by using enriched state DB data directly
  rather than reading rollout heads
