  • Filter Windows sandbox roots from SSH config dependencies (#18493)
    ## Stack
    
    1. Base PR: #18443 stops granting ACLs on `USERPROFILE`.
    2. This PR: filters additional SSH-owned profile roots discovered from
    SSH config.
    
    ## Bug
    
    The base PR removes the broadest bad grant: `USERPROFILE` itself.
    
    That still leaves one important case. A user profile child can be
    SSH-owned even when its name is not one of our fixed exclusions.
    
    For example:
    
    ```sshconfig
    Host devbox
      IdentityFile ~/.keys/devbox
      CertificateFile ~/.certs/devbox-cert.pub
      UserKnownHostsFile ~/.known_hosts_custom
      Include ~/.ssh/conf.d/*.conf
    ```
    
    After profile expansion, the sandbox might see these as normal profile
    children:
    
    ```text
    C:\Users\me\.keys
    C:\Users\me\.certs
    C:\Users\me\.known_hosts_custom
    C:\Users\me\.ssh
    ```
    
    Those paths have another owner: OpenSSH and the tools that manage SSH
    identity and host-key state. Codex should not add sandbox ACLs to them.
    
    OpenSSH describes this dependency tree in
    [`ssh_config(5)`](https://man.openbsd.org/ssh_config.5), and the client
    parser follows the same shape in `readconf.c`:
    
    - `Include` recursively reads more config files and expands globs
    - `IdentityFile` and `CertificateFile` name authentication files
    - `UserKnownHostsFile`, `GlobalKnownHostsFile`, and `RevokedHostKeys`
    name host-key files
    - `ControlPath` and `IdentityAgent` can name profile-owned sockets or
    control files
    - these path directives can use forms such as `~`, `%d`, and `${HOME}`
    
    ## Change
    
    This PR adds a small SSH config dependency scanner.
    
    It starts at:
    
    ```text
    ~/.ssh/config
    ```
    
    Then it returns concrete paths named by `Include` and by path-valued SSH
    config directives:
    
    ```text
    IdentityFile
    CertificateFile
    UserKnownHostsFile
    GlobalKnownHostsFile
    RevokedHostKeys
    ControlPath
    IdentityAgent
    ```
    
    For example:
    
    ```sshconfig
    IdentityFile ~/.keys/devbox
    CertificateFile ~/.certs/devbox-cert.pub
    Include ~/.ssh/conf.d/*.conf
    ```
    
    returns paths like:
    
    ```text
    C:\Users\me\.keys\devbox
    C:\Users\me\.certs\devbox-cert.pub
    C:\Users\me\.ssh\conf.d\devbox.conf
    ```
    
    The setup code then maps those paths back to their top-level
    `USERPROFILE` child and filters matching sandbox roots out of both the
    writable and readable root lists.
    
    ## Why this shape
    
    The parser reports what SSH config references. The sandbox setup code
    decides which `USERPROFILE` roots are unsafe to grant.
    
    That keeps the policy simple:
    
    1. expand broad profile grants
    2. remove the profile root
    3. remove fixed sensitive profile folders
    4. remove profile folders referenced by SSH config dependencies
    
    If a path has two possible owners, the sandbox steps back. SSH keeps
    control of SSH config, keys, certificates, known-hosts files, sockets,
    and included config files.
    
    ## Tests
    
    - `cargo test -p codex-windows-sandbox --lib`
    - `just bazel-lock-check`
    - `just fix -p codex-windows-sandbox`
    - `git diff --check`
  • feat: add opt-in provider runtime abstraction (#17713)
    ## 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.

  • Register agent tasks behind use_agent_identity (#17387)
    ## Summary
    
    Stack PR3 for feature-gated agent identity support.
    
    This PR adds per-thread agent task registration behind
    `features.use_agent_identity`. Tasks are minted on the first real user
    turn and cached in thread runtime state for later turns.
    
    ## Stack
    
    - PR1: https://github.com/openai/codex/pull/17385 - add
    `features.use_agent_identity`
    - PR2: https://github.com/openai/codex/pull/17386 - register agent
    identities when enabled
    - PR3: https://github.com/openai/codex/pull/17387 - this PR, original
    task registration slice
    - PR3.1: https://github.com/openai/codex/pull/17978 - persist and
    prewarm registered tasks per thread
    - PR4: https://github.com/openai/codex/pull/17980 - use `AgentAssertion`
    downstream when enabled
    
    ## Validation
    
    Covered as part of the local stack validation pass:
    
    - `just fmt`
    - `cargo test -p codex-core --lib agent_identity`
    - `cargo test -p codex-core --lib agent_assertion`

    - `cargo build -p codex-cli --bin codex`
    
    ## Notes
    
    The full local app-server E2E path is still being debugged after PR
    creation. The current branch stack is directionally ready for review
    while that follow-up continues.
  • [codex] Add remote thread store implementation (#17826)
    - Add a "remote" thread store implementation
    - Implement the remote thread store as a thin wrapper that makes grpc
    calls to a configurable service endpoint
    - Implement only the thread/list method to start
    - Encode the grpc method/param shape as protobufs in the remote
    implementation
    
    A wart: the proto generation script is an "example" binary target. This
    is an example target only because Cargo lets examples use
    dev-dependencies, which keeps tonic-prost-build out of the normal
    codex-thread-store dependency surface. A regular bin would either need
    to add proto generation deps as normal runtime deps, or use a
    feature-gated optional dep, which this repo’s manifest checks explicitly
    reject.

  • Significantly improve standalone installer (#17022)
    ## 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`

  • [codex] Add local thread store listing (#17824)
    Builds on top of #17659 
    
    Move the filesystem + sqlite thread listing-related operations inside of
    a local ThreadStore implementation and call ThreadStore from the places
    that used to perform these filesystem/sqlite operations.
    
    This is the first of a series of PRs that will implement the rest of the
    local ThreadStore.
    
    Testing:
    - added unit tests for the thread store implementation
    - adjusted some unit tests in the realtime + personality packages whose
    callsites changed. Specifically I'm trying to hide ThreadMetadata inside
    of the local implementation and make ThreadMetadata a sqlite
    implementation detail concern rather than a public interface, preferring
    the more generate StoredThread interface instead
    - added a corner case test for the personality migration package that
    wasn't covered by the existing test suite
    - adjust the behavior of searched thread listing to run the existing
    local rollout repair/backfill pass _before_ querying SQLite results, so
    callers using ThreadStore::list_threads do not miss matches after a
    partial metadata warm-up
  • Register agent identities behind use_agent_identity (#17386)
    ## Summary
    
    Stack PR 2 of 4 for feature-gated agent identity support.
    
    This PR adds agent identity registration behind
    `features.use_agent_identity`. It keeps the app-server protocol
    unchanged and starts registration after ChatGPT auth exists rather than
    requiring a client restart.
    
    ## Stack
    
    - PR1: https://github.com/openai/codex/pull/17385 - add
    `features.use_agent_identity`
    - PR2: https://github.com/openai/codex/pull/17386 - this PR
    - PR3: https://github.com/openai/codex/pull/17387 - register agent tasks
    when enabled
    - PR4: https://github.com/openai/codex/pull/17388 - use `AgentAssertion`
    downstream when enabled
    
    ## Validation
    
    Covered as part of the local stack validation pass:
    
    - `just fmt`
    - `cargo test -p codex-core --lib agent_identity`
    - `cargo test -p codex-core --lib agent_assertion`

    - `cargo test -p codex-api api_bridge`
    - `cargo build -p codex-cli --bin codex`
    
    ## Notes
    
    The full local app-server E2E path is still being debugged after PR
    creation. The current branch stack is directionally ready for review
    while that follow-up continues.
  • ThreadStore interface (#17659)
    Introduce a ThreadStore interface for mediating access to the filesystem

    In later PRs we'll move the existing fs code behind a "local"
    implementation of this ThreadStore interface.
    
    This PR should be a no-op behaviorally, it only introduces the

  • [codex] Initialize ICU data for code mode V8 (#17709)
    Link ICU data into code mode, otherwise locale-dependent methods cause a
    panic and a crash.
  • fix: pin inputs (#17471)
    ## Summary
    - Pin Rust git patch dependencies to immutable revisions and make
    cargo-deny reject unknown git and registry sources unless explicitly
    allowlisted.
    - Add checked-in SHA-256 coverage for the current rusty_v8 release
    assets, wire those hashes into Bazel, and verify CI override downloads
    before use.
    - Add rusty_v8 MODULE.bazel update/check tooling plus a Bazel CI guard
    so future V8 bumps cannot drift from the checked-in checksum manifest.
    - Pin release/lint cargo installs and all external GitHub Actions refs
    to immutable inputs.
    
    ## Future V8 bump flow
    Run these after updating the resolved `v8` crate version and checksum
    manifest:
    
    ```bash
    python3 .github/scripts/rusty_v8_bazel.py update-module-bazel
    python3 .github/scripts/rusty_v8_bazel.py check-module-bazel
    ```
    
    The update command rewrites the matching `rusty_v8_<crate_version>`
    `http_file` SHA-256 values in `MODULE.bazel` from
    `third_party/v8/rusty_v8_<crate_version>.sha256`. The check command is
    also wired into Bazel CI to block drift.
    
    ## Notes
    - This intentionally excludes RustSec dependency upgrades and
    bubblewrap-related changes per request.
    - The branch was rebased onto the latest origin/main before opening the
    PR.
    
    ## Validation
    - cargo fetch --locked
    - cargo deny check advisories
    - cargo deny check
    - cargo deny check sources
    - python3 .github/scripts/rusty_v8_bazel.py check-module-bazel
    - python3 .github/scripts/rusty_v8_bazel.py update-module-bazel
    - python3 -m unittest discover -s .github/scripts -p
    'test_rusty_v8_bazel.py'
    - python3 -m py_compile .github/scripts/rusty_v8_bazel.py
    .github/scripts/rusty_v8_module_bazel.py
    .github/scripts/test_rusty_v8_bazel.py
    - repo-wide GitHub Actions `uses:` audit: all external action refs are
    pinned to 40-character SHAs
    - yq eval on touched workflows and local actions
    - git diff --check
    - just bazel-lock-check
    
    ## Hash verification
    - Confirmed `MODULE.bazel` hashes match
    `third_party/v8/rusty_v8_146_4_0.sha256`.
    - Confirmed GitHub release asset digests for denoland/rusty_v8
    `v146.4.0` and openai/codex `rusty-v8-v146.4.0` match the checked-in
    hashes.
    - Streamed and SHA-256 hashed all 10 `MODULE.bazel` rusty_v8 asset URLs
    locally; every downloaded byte stream matched both `MODULE.bazel` and
    the checked-in manifest.
    
    ## Pin verification
    - Confirmed signing-action pins match the peeled commits for their tag
    comments: `sigstore/cosign-installer@v3.7.0`, `azure/login@v2`, and
    `azure/trusted-signing-action@v0`.
    - Pinned the remaining tag-based action refs in Bazel CI/setup:
    `actions/setup-node@v6`, `facebook/install-dotslash@v2`,
    `bazelbuild/setup-bazelisk@v3`, and `actions/cache/restore@v5`.
    - Normalized all `bazelbuild/setup-bazelisk@v3` refs to the peeled
    commit behind the annotated tag.
    - Audited Cargo git dependencies: every manifest git dependency uses
    `rev` only, every `Cargo.lock` git source has `?rev=<sha>#<same-sha>`,
    and `cargo deny check sources` passes with `required-git-spec = "rev"`.
    - Shallow-fetched each distinct git dependency repo at its pinned SHA
    and verified Git reports each object as a commit.

  • Revert "Option to Notify Workspace Owner When Usage Limit is Reached" (#17391)
    Reverts openai/codex#16969
    
    #sev3-2026-04-10-accountscheckversion-500s-for-openai-workspace-7300
  • Option to Notify Workspace Owner When Usage Limit is Reached (#16969)
    ## Summary
    - Replace the manual `/notify-owner` flow with an inline confirmation
    prompt when a usage-based workspace member hits a credits-depleted
    limit.
    - Fetch the current workspace role from the live ChatGPT
    `accounts/check/v4-2023-04-27` endpoint so owner/member behavior matches
    the desktop and web clients.
    - Keep owner, member, and spend-cap messaging distinct so we only offer
    the owner nudge when the workspace is actually out of credits.
    
    ## What Changed
    - `backend-client`
    - Added a typed fetch for the current account role from
    `accounts/check`.
      - Mapped backend role values into a Rust workspace-role enum.
    - `app-server` and protocol
      - Added `workspaceRole` to `account/read` and `account/updated`.
    - Derived `isWorkspaceOwner` from the live role, with a fallback to the
    cached token claim when the role fetch is unavailable.
    - `tui`
      - Removed the explicit `/notify-owner` slash command.
    - When a member is blocked because the workspace is out of credits, the
    error now prompts:
    - `Your workspace is out of credits. Request more from your workspace
    owner? [y/N]`
      - Choosing `y` sends the existing owner-notification request.
    - Choosing `n`, pressing `Esc`, or accepting the default selection
    dismisses the prompt without sending anything.
    - Selection popups now honor explicit item shortcuts, which is how the
    `y` / `n` interaction is wired.
    
    ## Reviewer Notes
    - The main behavior change is scoped to usage-based workspace members
    whose workspace credits are depleted.
    - Spend-cap reached should not show the owner-notification prompt.
    - Owners and admins should continue to see `/usage` guidance instead of
    the member prompt.
    - The live role fetch is best-effort; if it fails, we fall back to the
    existing token-derived ownership signal.

  • Move default realtime prompt into core (#17165)
    - Adds a core-owned realtime backend prompt template and preparation
    path.
    - Makes omitted realtime start prompts use the core default, while null
    or empty prompts intentionally send empty instructions.
    - Covers the core realtime path and app-server v2 path with integration
    coverage.

  • Add WebRTC media transport to realtime TUI (#17058)
    Adds the `[realtime].transport = "webrtc"` TUI media path using a new
    `codex-realtime-webrtc` crate, while leaving app-server as the
    signaling/event source.\n\nLocal checks: fmt, diff-check, dependency

  • 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`

  • 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.
  • cloud-tasks: split the mock client out of cloud-tasks-client (#16456)
    ## Why
    
    `codex-cloud-tasks-client` was mixing two different roles: the real HTTP
    client and the mock implementation used by tests and local mock mode.
    Keeping both in the same crate forced Cargo feature toggles and Bazel
    `crate_features` just to pick an implementation.
    
    This change keeps `codex-cloud-tasks-client` focused on the shared API
    surface and real backend client, and moves the mock implementation into
    its own crate so we can remove those feature permutations cleanly.
    
    ## What changed
    
    - add a new `codex-cloud-tasks-mock-client` crate that owns `MockClient`
    - remove the `mock` and `online` features from
    `codex-cloud-tasks-client`
    - make `codex-cloud-tasks-client` unconditionally depend on
    `codex-backend-client` and export `HttpClient` directly
    - gate the mock-mode path in `codex-cloud-tasks` behind
    `#[cfg(debug_assertions)]`, so release builds always initialize the real
    HTTP client
    - update `codex-cloud-tasks` and its tests to use
    `codex-cloud-tasks-mock-client::MockClient` wherever mock behavior is
    needed
    - remove the matching Bazel `crate_features` override and shrink the
    manifest verifier allowlist accordingly
    
    ## How tested
    
    - `cargo test -p codex-cloud-tasks-client`
    - `cargo test -p codex-cloud-tasks-mock-client`
    - `cargo test -p codex-cloud-tasks`

  • Rename tui_app_server to tui (#16104)
    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.
  • Remove the legacy TUI split (#15922)
    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.
  • 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
  • fix: box apply_patch test harness futures (#15835)
    ## Why
    
    `#[large_stack_test]` made the `apply_patch_cli` tests pass by giving
    them more stack, but it did not address why those tests needed the extra
    stack in the first place.
    
    The real problem is the async state built by the `apply_patch_cli`
    harness path. Those tests await three helper boundaries directly:
    harness construction, turn submission, and apply-patch output
    collection. If those helpers inline their full child futures, the test
    future grows to include the whole harness startup and request/response
    path.
    
    This change replaces the workaround from #12768 with the same basic
    approach used in #13429, but keeps the fix narrower: only the helper
    boundaries awaited directly by `apply_patch_cli` stay boxed.
    
    ## What Changed
    
    - removed `#[large_stack_test]` from
    `core/tests/suite/apply_patch_cli.rs`
    - restored ordinary `#[tokio::test(flavor = "multi_thread",
    worker_threads = 2)]` annotations in that suite
    - deleted the now-unused `codex-test-macros` crate and removed its
    workspace wiring
    - boxed only the three helper boundaries that the suite awaits directly:
      - `apply_patch_harness_with(...)`
      - `TestCodexHarness::submit(...)`
      - `TestCodexHarness::apply_patch_output(...)`
    - added comments at those boxed boundaries explaining why they remain
    boxed
    
    ## Testing
    
    - `cargo test -p codex-core --test all suite::apply_patch_cli --
    --nocapture`

  • feat: exec-server prep for unified exec (#15691)
    This PR partially rebase `unified_exec` on the `exec-server` and adapt
    the `exec-server` accordingly.
    
    ## What changed in `exec-server`
    
    1. Replaced the old "broadcast-driven; process-global" event model with
    process-scoped session events. The goal is to be able to have dedicated
    handler for each process.
    2. Add to protocol contract to support explicit lifecycle status and
    stream ordering:
    - `WriteResponse` now returns `WriteStatus` (Accepted, UnknownProcess,
    StdinClosed, Starting) instead of a bool.
      - Added seq fields to output/exited notifications.
      - Added terminal process/closed notification.
    3. Demultiplexed remote notifications into per-process channels. Same as
    for the event sys
    4. Local and remote backends now both implement ExecBackend.
    5. Local backend wraps internal process ID/operations into per-process
    ExecProcess objects.
    6. Remote backend registers a session channel before launch and
    unregisters on failed launch.
    
    ## What changed in `unified_exec`
    
    1. Added unified process-state model and backend-neutral process
    wrapper. This will probably disappear in the future, but it makes it
    easier to keep the work flowing on both side.
    - `UnifiedExecProcess` now handles both local PTY sessions and remote
    exec-server processes through a shared `ProcessHandle`.
    - Added `ProcessState` to track has_exited, exit_code, and terminal
    failure message consistently across backends.
    2. Routed write and lifecycle handling through process-level methods.
    
    ## Some rationals
    
    1. The change centralizes execution transport in exec-server while
    preserving policy and orchestration ownership in core, avoiding
    duplicated launch approval logic. This comes from internal discussion.
    2. Session-scoped events remove coupling/cross-talk between processes
    and make stream ordering and terminal state explicit (seq, closed,
    failed).
    3. The failure-path surfacing (remote launch failures, write failures,
    transport disconnects) makes command tool output and cleanup behavior
    deterministic
    
    ## Follow-ups:
    * Unify the concept of thread ID behind an obfuscated struct
    * FD handling
    * Full zsh-fork compatibility
    * Full network sandboxing compatibility
    * Handle ws disconnection

  • 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.

  • Move macOS sandbox builders into codex-sandboxing (#15593)
    ## Summary
    - move macOS permission merging/intersection logic and tests from
    `codex-core` into `codex-sandboxing`
    - move seatbelt policy builders, permissions logic, SBPL assets, and

    - 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
  • Extract landlock helpers into codex-sandboxing (#15592)

    - 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
  • Code mode on v8 (#15276)
    Moves Code Mode to a new crate with no dependencies on codex. This
    create encodes the code mode semantics that we want for lifetime,
    mounting, tool calling.
    
    The model-facing surface is mostly unchanged. `exec` still runs raw
    JavaScript, `wait` still resumes or terminates a `cell_id`, nested tools
    are still available through `tools.*`, and helpers like `text`, `image`,
    `store`, `load`, `notify`, `yield_control`, and `exit` still exist.
    
    The major change is underneath that surface:
    
    - Old code mode was an external Node runtime.
    - New code mode is an in-process V8 runtime embedded directly in Rust.
    - Old code mode managed cells inside a long-lived Node runner process.
    - New code mode manages cells in Rust, with one V8 runtime thread per
    active `exec`.
    - Old code mode used JSON protocol messages over child stdin/stdout plus
    Node worker-thread messages.
    - New code mode uses Rust channels and direct V8 callbacks/events.
    
    This PR also fixes the two migration regressions that fell out of that
    substrate change:
    
    - `wait { terminate: true }` now waits for the V8 runtime to actually
    stop before reporting termination.
    - synchronous top-level `exit()` now succeeds again instead of surfacing
    as a script error.
    
    ---
    
    - `core/src/tools/code_mode/*` is now mostly an adapter layer for the
    public `exec` / `wait` tools.
    - `code-mode/src/service.rs` owns cell sessions and async control flow
    in Rust.
    - `code-mode/src/runtime/*.rs` owns the embedded V8 isolate and
    JavaScript execution.
    - each `exec` spawns a dedicated runtime thread plus a Rust
    session-control task.
    - helper globals are installed directly into the V8 context instead of
    being injected through a source prelude.
    - helper modules like `tools.js` and `@openai/code_mode` are synthesized
    through V8 module resolution callbacks in Rust.
    
    ---
    
    Also added a benchmark for showing the speed of init and use of a code
    mode env:

  • Add v8-poc consumer of our new built v8 (#15203)
    This adds a dummy v8-poc project that in Cargo links against our
    prebuilt binaries and the ones provided by rusty_v8 for non musl
    platforms. This demonstrates that we can successfully link and use v8 on
    all platforms that we want to target.
    
    In bazel things are slightly more complicated. Since the libraries as
    published have libc++ linked in already we end up with a lot of double
    linked symbols if we try to use them in bazel land. Instead we fall back
    to building rusty_v8 and v8 from source (cached of course) on the
    platforms we ship to.
    
    There is likely some compatibility drift in the windows bazel builder
    that we'll need to reconcile before we can re-enable them. I'm happy to
    be on the hook to unwind that.
  • Split features into codex-features crate (#15253)
    - Split the feature system into a new `codex-features` crate.
    - Cut `codex-core` and workspace consumers over to the new config and
    warning APIs.

  • Move terminal module to terminal-detection crate (#15216)
    - Move core/src/terminal.rs and its tests into a standalone
    terminal-detection workspace crate.
    - Update direct consumers to depend on codex-terminal-detection and
    import terminal APIs directly.

  • [hooks] use a user message > developer message for prompt continuation (#14867)
    ## Summary
    
    Persist Stop-hook continuation prompts as `user` messages instead of
    hidden `developer` messages + some requested integration tests
    
    This is a followup to @pakrym 's comment in
    https://github.com/openai/codex/pull/14532 to make sure stop-block
    continuation prompts match training for turn loops
    
    - Stop continuation now writes `<hook_prompt hook_run_id="...">stop
    hook's user prompt<hook_prompt>`
    - Introduces quick-xml dependency, though we already indirectly depended
    on it anyway via syntect
    - This PR only has about 500 lines of actual logic changes, the rest is
    tests/schema
    
    ## Testing
    
    Example run (with a sessionstart hook and 3 stop hooks) - this shows
    context added by session start, then two stop hooks sending their own
    additional prompts in a new turn. The model responds with a single
    message addressing both. Then when that turn ends, the hooks detect that
    they just ran using `stop_hook_active` and decide not to infinite loop
    
    test files for this (unzip, move codex -> .codex):

  • Move environment abstraction into exec server (#15125)
    The idea is that codex-exec exposes an Environment struct with services
    on it. Each of those is a trait.
    
    Depending on construction parameters passed to Environment they are
    either backed by local or remote server but core doesn't see these
    differences.
  • Add exec-server stub server and protocol docs (#15089)
    Stacked PR 1/3.
    
    This is the initialize-only exec-server stub slice: binary/client
    scaffolding and protocol docs, without exec/filesystem implementation.

  • Add FS abstraction and use in view_image (#14960)
    Adds an environment crate and environment + file system abstraction.
    
    Environment is a combination of attributes and services specific to
    environment the agent is connected to:
    File system, process management, OS, default shell.
    
    The goal is to move most of agent logic that assumes environment to work
    through the environment abstraction.
  • Move TUI on top of app server (parallel code) (#14717)
    This PR replicates the `tui` code directory and creates a temporary
    parallel `tui_app_server` directory. It also implements a new feature
    flag `tui_app_server` to select between the two tui implementations.
    
    Once the new app-server-based TUI is stabilized, we'll delete the old
    `tui` directory and feature flag.
