  • [codex] Support multiple forced ChatGPT workspaces (#18161)
    ## Summary
    
    This change lets `forced_chatgpt_workspace_id` accept multiple workspace
    IDs instead of a single value.
    
    It keeps the existing config key name, adds backward-compatible parsing
    for a single string in `config.toml`, and normalizes the setting into an
    allowed workspace list across login enforcement, app-server config
    surfaces, and local ChatGPT auth helpers.
    
    ## Why
    
    Workspace-restricted deployments may need to allow more than one ChatGPT
    workspace without dropping the guardrail entirely.
    
    ## Server-side impact
    
    Codex's local server and app-server protocol needed changes because they
    previously assumed a single workspace ID. The local login flow now
    matches the auth backend interface by sending the allowed workspace list
    as a single comma-separated `allowed_workspace_id` query parameter.
    
    ## Validation
    
    This was tested with:
    
    - A single workspace config
    - With multi-workspace configs
    - With multiple workspaces in the config
    - The user only being a part of a subset of them
    
    All were successful.
    
    Automated coverage:
    
    - `cargo test -p codex-login`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-tui local_chatgpt_auth`
    - `cargo test --locked -p codex-app-server

  • Prefer the model list fetched from the backend for SIWC users (#22547)
    ## Summary
    - For SIWC users, update the model list merging logic to prefer the
    model list fetched from the backend over the bundled model list (this is
    needed for special cases where users have a more limited set of models
    they're allowed to use)
    - Add or update tests covering the revised cache behavior
    
    ## Testing
    - Added/updated unit tests in
    `codex-rs/models-manager/src/manager_tests.rs`
    - Not run (not requested)
  • tests: avoid ambient temp sandbox roots (#22576)
    ## Why
    Some sandboxed integration tests enabled both ambient temp roots
    (`TMPDIR` and literal `/tmp`) even though they were not testing
    temp-root behavior. On Linux bwrap, making `/tmp` writable causes
    protected metadata mount targets such as `/tmp/.git`, `/tmp/.agents`,
    and `/tmp/.codex` to be synthesized. If a run is interrupted, those
    top-level markers can be left behind and contaminate later tests.
    
    ## What changed
    For the incidental integration tests that do not need ambient temp-root
    access, set `exclude_tmpdir_env_var` and `exclude_slash_tmp` to `true`.
    Dedicated protected-metadata coverage remains in the lower-level sandbox
    tests that use isolated temp roots.
    
    ## Verification
    Focused remote devbox repros passed with a watcher polling `/tmp/.git`,
    `/tmp/.agents`, and `/tmp/.codex`; no leaked markers were observed.
  • permissions: canonicalize workspace_roots and danger-full-access names (#22624)
    ## Why
    
    This is a small precursor to the larger permissions-migration work. Both
    the comparison stack in
    [#22401](https://github.com/openai/codex/pull/22401) /
    [#22402](https://github.com/openai/codex/pull/22402) and the alternate
    stack in [#22610](https://github.com/openai/codex/pull/22610) /
    [#22611](https://github.com/openai/codex/pull/22611) /
    [#22612](https://github.com/openai/codex/pull/22612) are easier to
    review if the terminology is already settled underneath them.
    
    Because `:project_roots` and `:danger-no-sandbox` have not shipped as
    stable user-facing surface area, carrying them forward as aliases would
    just add more migration logic to the later stacks. This PR removes that
    ambiguity now so the follow-on work can rely on one spelling for each
    built-in concept.
    
    ## What Changed
    
    - renamed the config-facing special filesystem key from `:project_roots`
    to `:workspace_roots`
    - dropped unpublished `:project_roots` parsing support in
    `core/src/config/permissions.rs`, so new config only recognizes
    `:workspace_roots`
    - renamed the built-in full-access permission profile id from
    `:danger-no-sandbox` to `:danger-full-access`
    - dropped unpublished `:danger-no-sandbox` support entirely, including
    the old active-profile canonicalization path, and added explicit
    rejection coverage for the legacy id
    - introduced shared built-in permission-profile id constants in
    `codex-rs/protocol/src/models.rs`
    - updated `core`, `app-server`, and `tui` call sites that special-case
    built-in profiles to use the shared constants and canonical ids
    - updated tests and the Linux sandbox README to use `:workspace_roots` /
    `:danger-full-access`
    
    ## Verification
    
    I focused verification on the three places this rename can regress:
    config parsing, active-profile identity surfaced back out of `core`, and
    user/server call sites that special-case built-in profiles.

  • feat: add layered --profile-v2 config files (#17141)
    ## Why
    
    `--profile-v2 <name>` gives launchers and runtime entry points a named
    profile config without making each profile duplicate the base user
    config. The base `$CODEX_HOME/config.toml` still loads first, then
    `$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
    writable user config for that session.
    
    That keeps shared defaults, plugin/MCP setup, and managed/user
    constraints in one place while letting a named profile override only the
    pieces that need to differ.
    
    ## What Changed
    
    - Added the shared `--profile-v2 <name>` runtime option with validated
    plain names, now represented by `ProfileV2Name`.
    - Extended config layer state so the base user config and selected
    profile config are both `User` layers; APIs expose the active user layer
    and merged effective user config.
    - Threaded profile selection through runtime entry points: `codex`,
    `codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
    debug prompt-input`.
    - Made user-facing config writes go to the selected profile file when
    active, including TUI/settings persistence, app-server config writes,
    and MCP/app tool approval persistence.
    - Made plugin, marketplace, MCP, hooks, and config reload paths read
    from the merged user config so base and profile layers both participate.
    - Updated app-server config layer schemas to mark profile-backed user
    layers.
    
    ## Limits
    
    `--profile-v2` is still rejected for config-management subcommands such
    as feature, MCP, and marketplace edits. Those paths remain tied to the
    base `config.toml` until they have explicit profile-selection semantics.
    
    Some adjacent background writes may still update base or global state
    rather than the selected profile:
    
    - marketplace auto-upgrade metadata
    - automatic MCP dependency installs from skills
    - remote plugin sync or uninstall config edits
    - personality migration marker/default writes
    
    ## Verification
    
    Added targeted coverage for profile name validation, layer
    ordering/merging, selected-profile writes, app-server config writes,
    session hot reload, plugin config merging, hooks/config fixture updates,
    and MCP/app approval persistence.

  • Relax remote plugin sync gate (#22594)
    ## Summary
    - Allow remote installed-plugin cache refresh to start whenever plugins
    are enabled.
    - Allow remote installed-plugin bundle sync to start whenever plugins
    are enabled.
    - Remove the extra local `remote_plugin_enabled` guard from those
    background sync paths.
    
    ## Context
    Server-side installed plugin state and optional bundle URL behavior are
    owned by plugin-service `/public/plugins/installed`, so these local sync
    paths only need the overall plugin enablement gate.
    
    ## Test plan
    - `just fmt`
    - `cargo test -p codex-core-plugins`
  • enable/disable remote control at runtime, not via features (#22578)
    ## Why
    reapplies https://github.com/openai/codex/pull/22386 which was
    previously reverted
    
    Also, introduce `remoteControl/enable` and `remoteControl/disable`
    app-server APIs to toggle on/off remote control at runtime for a given
    running app-server instance.
    
    ## What Changed
    
    - Adds experimental v2 RPCs:
      - `remoteControl/enable`
      - `remoteControl/disable`
    - Adds `RemoteControlRequestProcessor` and routes the new RPCs through
    it instead of `ConfigRequestProcessor`.
    - Adds named `RemoteControlHandle::enable`, `disable`, and `status`
    methods.
    - Makes `remoteControl/enable` return an error when sqlite state DB is
    unavailable, while keeping enrollment/websocket failures as async status
    updates.
    - Adds `AppServerRuntimeOptions.remote_control_enabled` and hidden
    `--remote-control` flags for `codex app-server` and `codex-app-server`.
    - Updates managed daemon startup to use `codex app-server
    --remote-control --listen unix://`.
    - Marks `Feature::RemoteControl` as removed and ignores
    `[features].remote_control`.
    - Updates app-server README entries for the new remote-control methods.
  • [codex] Canonicalize shared workspace plugin IDs (#22564)
    ## Summary
    - Canonicalize private and unlisted workspace shared plugin IDs to
    `workspace-shared-with-me`.
    - Keep `plugin/list` private/unlisted shared-with-me buckets as UI
    grouping only.
    - Update share read/list/checkout and cache cleanup coverage for the
    canonical namespace.
    
    ## Tests
    - `cargo test -p codex-app-server --test all
    plugin_list_fetches_shared_with_me_kind`
    - `cargo test -p codex-app-server --test all

  • fix: prevent codex-backend from stealing originator (#22533)
    ## Why
    
    Remote control starts by letting `codex-backend` initialize against the
    app-server as an infrastructure health/proxy client before the real
    remote client connects. App-server initialization also sets the
    process-wide `originator` from `client_info.name`, so `codex-backend`
    could become the sticky originator for later model/API requests even
    after the real client initialized.
    
    ## What changed
    
    - Treat `codex-backend` as a non-originating initialize client,
    alongside the existing `codex_app_server_daemon` probe client.
    - Preserve normal per-connection initialize behavior, including session
    metadata and initialize analytics.
    - Add regression coverage that verifies `codex-backend` initialize does
    not replace the default originator.
    
    ## Testing
    
    - `cargo test -p codex-app-server --test all
    initialize_codex_backend_does_not_override_originator`
  • chore(config) rm tools.view_image (#22501)
    ## Summary
    It appears this config flag has been broken/a noop for quite some time:
    since https://github.com/openai/codex/pull/8850. Let's simplify and get
    rid of this.
    
    ## Testing
    - [x] Updated unit tests
  • config: add strict config parsing (#20559)
    ## Why
    
    Codex intentionally ignores unknown `config.toml` fields by default so
    older and newer config files keep working across versions. That leniency
    also makes typo detection hard because misspelled or misplaced keys
    disappear silently.
    
    This change adds an opt-in strict config mode so users and tooling can
    fail fast on unrecognized config fields without changing the default
    permissive behavior.
    
    This feature is possible because `serde_ignored` exposes the exact
    signal Codex needs: it lets Codex run ordinary Serde deserialization
    while recording fields Serde would otherwise ignore. That avoids
    requiring `#[serde(deny_unknown_fields)]` across every config type and
    keeps strict validation opt-in around the existing config model.
    
    ## What Changed
    
    ### Added strict config validation
    
    - Added `serde_ignored`-based validation for `ConfigToml` in
    `codex-rs/config/src/strict_config.rs`.
    - Combined `serde_ignored` with `serde_path_to_error` so strict mode
    preserves typed config error paths while also collecting fields Serde
    would otherwise ignore.
    - Added strict-mode validation for unknown `[features]` keys, including
    keys that would otherwise be accepted by `FeaturesToml`'s flattened
    boolean map.
    - Kept typed config errors ahead of ignored-field reporting, so
    malformed known fields are reported before unknown-field diagnostics.
    - Added source-range diagnostics for top-level and nested unknown config
    fields, including non-file managed preference source names.
    
    ### Kept parsing single-pass per source
    
    - Reworked file and managed-config loading so strict validation reuses
    the already parsed `TomlValue` for that source.
    - For actual config files and managed config strings, the loader now
    reads once, parses once, and validates that same parsed value instead of
    deserializing multiple times.
    - Validated `-c` / `--config` override layers with the same
    base-directory context used for normal relative-path resolution, so
    unknown override keys are still reported when another override contains
    a relative path.
    
    ### Scoped `--strict-config` to config-heavy entry points
    
    - Added support for `--strict-config` on the main config-loading entry
    points where it is most useful:
      - `codex`
      - `codex resume`
      - `codex fork`
      - `codex exec`
      - `codex review`
      - `codex mcp-server`
      - `codex app-server` when running the server itself
      - the standalone `codex-app-server` binary
      - the standalone `codex-exec` binary
    - Commands outside that set now reject `--strict-config` early with
    targeted errors instead of accepting it everywhere through shared CLI
    plumbing.
    - `codex app-server` subcommands such as `proxy`, `daemon`, and
    `generate-*` are intentionally excluded from the first rollout.
    - When app-server strict mode sees invalid config, app-server exits with
    the config error instead of logging a warning and continuing with
    defaults.
    - Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
    instead of extending shared `ReviewArgs`, so `--strict-config` stays on
    the outer config-loading command surface and does not become part of the
    reusable review payload used by `codex exec review`.
    
    ### Coverage
    
    - Added tests for top-level and nested unknown config fields, unknown
    `[features]` keys, typed-error precedence, source-location reporting,
    and non-file managed preference source names.
    - Added CLI coverage showing invalid `--enable`, invalid `--disable`,
    and unknown `-c` overrides still error when `--strict-config` is
    present, including compound-looking feature names such as
    `multi_agent_v2.subagent_usage_hint_text`.
    - Added integration coverage showing both `codex app-server
    --strict-config` and standalone `codex-app-server --strict-config` exit
    with an error for unknown config fields instead of starting with
    fallback defaults.
    - Added coverage showing unsupported command surfaces reject
    `--strict-config` with explicit errors.
    
    ## Example Usage
    
    Run Codex with strict config validation enabled:
    
    ```shell
    codex --strict-config
    ```
    
    Strict config mode is also available on the supported config-heavy
    subcommands:
    
    ```shell
    codex --strict-config exec "explain this repository"
    codex review --strict-config --uncommitted
    codex mcp-server --strict-config
    codex app-server --strict-config --listen off
    codex-app-server --strict-config --listen off
    ```
    
    For example, if `~/.codex/config.toml` contains a typo in a key name:
    
    ```toml
    model = "gpt-5"
    approval_polic = "on-request"
    ```
    
    then `codex --strict-config` reports the misspelled key instead of
    silently ignoring it. The path is shortened to `~` here for readability:
    
    ```text
    $ codex --strict-config
    Error loading config.toml:
    ~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
      |
    2 | approval_polic = "on-request"
      | ^^^^^^^^^^^^^^
    ```
    
    Without `--strict-config`, Codex keeps the existing permissive behavior
    and ignores the unknown key.
    
    Strict config mode also validates ad-hoc `-c` / `--config` overrides:
    
    ```text
    $ codex --strict-config -c foo=bar
    Error: unknown configuration field `foo` in -c/--config override
    
    $ codex --strict-config -c features.foo=true
    Error: unknown configuration field `features.foo` in -c/--config override
    ```
    
    Invalid feature toggles are rejected too, including values that look
    like nested config paths:
    
    ```text
    $ codex --strict-config --enable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --disable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
    Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
    ```
    
    Unsupported commands reject the flag explicitly:
    
    ```text
    $ codex --strict-config cloud list
    Error: `--strict-config` is not supported for `codex cloud`
    ```
    
    ## Verification
    
    The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
    `--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
    case, unknown `-c` overrides, app-server strict startup failure through
    `codex app-server`, and rejection for unsupported commands such as
    `codex cloud`, `codex mcp`, `codex remote-control`, and `codex
    app-server proxy`.
    
    The config and config-loader tests cover unknown top-level fields,
    unknown nested fields, unknown `[features]` keys, source-location
    reporting, non-file managed config sources, and `-c` validation for keys
    such as `features.foo`.
    
    The app-server test suite covers standalone `codex-app-server
    --strict-config` startup failure for an unknown config field.
    
    ## Documentation
    
    The Codex CLI docs on developers.openai.com/codex should mention
    `--strict-config` as an opt-in validation mode for supported
    config-heavy entry points once this ships.
  • feat: Add plugin share checkout (#22435)
    Adds plugin/share/checkout to turn a shared remote plugin into a local

  • Use root repo hooks in linked worktrees (#21969)
    # Why
    
    Linked worktrees currently load their own project hook declarations, so
    the same repo can present different hook definitions depending on which
    checkout is active. https://github.com/openai/codex/pull/21762 tried to
    share trust by giving matching worktree hooks a shared synthetic key,
    but review pointed out that divergent worktree hook definitions would
    then fight over one `trusted_hash`.
    
    Instead of introducing a second trust model, this makes linked worktrees
    use the root checkout as the single source of truth for project hook
    declarations. Worktree-local project config can still diverge for
    unrelated settings, but project hooks now keep one real source path and
    one trust state per repo.
    
    # What
    
    - Teach project config loading to remember the matching root-checkout
    `.codex/` folder for actual linked-worktree project layers.
    - Keep ordinary project config sourced from the worktree, but replace
    project hook declarations with the root checkout's matching layer before
    hook discovery runs, including linked-worktree layers with `.codex/` but
    no local `config.toml`.
    - Make hook discovery use that authoritative hook folder for both
    `hooks.json` and TOML hook source paths, so linked worktrees produce the
    same hook key and trust state as the root checkout.
    - Cover the linked-worktree path plus regressions for missing worktree
    `config.toml` and nested non-worktree project roots.
  • feat: Split shared workspace plugins by discoverability (#22425)
    - Keep shared-with-me as the plugin/list request kind, but return

    - Add workspace-shared-with-me-unlisted for installed workspace plugins
    with UNLISTED discoverability,
  • Restore app-server websocket listener with auth guard (#22404)
    ## Why
    PR #21843 removed the TCP websocket app-server listener, but that also
    removed functionality that still needs to exist. Restoring it as-is
    would reopen the old remote exposure problem, so this keeps the restored
    listener while making remote and non-loopback usage require explicit
    auth.
    
    ## What Changed
    - Mostly reverts #21843 and reapplies the small merge-conflict
    resolutions needed on top of current main.
    - Restores ws://IP:PORT parsing, the app-server TCP websocket acceptor,
    websocket auth CLI flags, and the associated tests.
    - The only intentional behavior change from the restored code is that
    non-loopback websocket listeners now fail startup unless --ws-auth
    capability-token or --ws-auth signed-bearer-token is configured.
    Loopback listeners remain available for local and SSH-forwarding
    workflows.
    
    ## Reviewer Focus
    Please focus review on the small auth-enforcement delta layered on top
    of the revert:
    
    - codex-rs/app-server-transport/src/transport/websocket.rs:
    start_websocket_acceptor now rejects unauthenticated non-loopback
    websocket binds before accepting connections.
    - codex-rs/app-server-transport/src/transport/auth.rs: helper logic
    classifies unauthenticated non-loopback listeners.
    - codex-rs/app-server/tests/suite/v2/connection_handling_websocket.rs:
    tests cover unauthenticated ws://0.0.0.0 startup rejection and
    authenticated non-loopback capability-token startup.
    
    Everything else is intended to be revert/merge-conflict restoration
    rather than new product behavior.
    
    ## Verification
    
    - Manually verified that TUI remoting is restored and that auth is
    enforced for non-localhost urls.
  • feat: Expose plugin versions and gate plugin sharing (#22397)
    - Adds localVersion to plugin summaries and remoteVersion to share
    context, including generated API schemas.
    - Hydrates local and remote plugin versions from manifests and remote
    release metadata.
    - Adds default-on plugin_sharing gate for shared-with-me listing and
    plugin/share/save, with disabled-path errors
        and focused coverage.
  • Unify thread metadata updates above store (#22236)
    - make ThreadStore::update_thread_metadata accept a broad range of
    metadata patches
    - keep ThreadStore::append_items as raw canonical history append (no
    metadata side effects)
    - in the local store, write these metadata updates to a combination of
    sqlite and rollout jsonl files for backwards-compat. It special cases
    which fields need to go into jsonl vs sqlite vs whatever, confining the
    awkwardness to just this implementation
    - in remote stores we can simply persist the metadata directly to a
    database, no special casing required.
    - move the "implicit metadata updates triggered by appending rollout
    items" from the RolloutRecorder (which is local-threadstore-specific) to
    the LiveThread layer above the ThreadStore, inside of a private helper
    utility called ThreadMetadataSync. LiveThread calls ThreadStore
    append_items and update_metadata separately.
    - Add a generic update metadata method to ThreadManager that works on
    both live threads and "cold" threads
    - Call that ThreadManager method from app server code, so app server
    doesn't need to worry about whether the thread is live or not

  • Add Windows hook command overrides (#22159)
    # Why
    
    Managed hook configs need a shared cross-platform shape without making
    the existing `command` field polymorphic. The common case is still one
    command string, with Windows needing a different entrypoint only when
    the runtime is actually Windows.
    
    Keeping `command` as the portable/default path and adding an optional
    Windows override keeps the config easier to read, preserves the existing
    scalar shape for non-Windows users, and avoids forcing every caller into
    a `{ unix, windows }` object when only one platform needs special
    handling.
    
    # What
    
    - Add optional `command_windows` / `commandWindows` alongside the
    existing hook `command` field.
    - Resolve `command_windows` only on Windows during hook discovery; other
    platforms continue to use `command` unchanged.
    - Keep trust hashing aligned to the effective command selected for the
    current runtime.
    
    # Docs
    
    The Codex hooks/config reference should document `command_windows` as
    the Windows-only override for command hooks.
  • fix(app-server): thread history redaction for remote clients (#22178)
    ## Summary
    
    Remote clients can still receive large `thread/resume` histories when
    prior turns include MCP tool call payloads or image-generation results.
    This adds a temporary response-only redaction path for the known remote
    client names.
    
    Longer term we will move towards fully paginated APIs backed by SQLite.
    
    ## Changes
    
    - Redact MCP tool call payload-bearing fields in `thread/resume`
    responses for `codex_chatgpt_android_remote` and
    `codex_chatgpt_ios_remote`.
    - Drop `imageGeneration` items from those `thread/resume` responses.
    - Keep redaction out of persisted rollout files, `thread/read`,
    `thread/turns/list`, live notifications, and token usage replay.
    - Cover the behavior with app-server helper tests and a v2 resume
    integration test that checks both remote clients plus a non-target
    control client.
    
    ## Testing
    
    - `cargo test -p codex-app-server thread_resume_redaction`
    - `cargo test -p codex-app-server
    thread_resume_redacts_payloads_for_chatgpt_remote_clients`
  • Unified mentions in TUI (#19068)
    This PR replaces the TUI’s file-only `@mention` popup with a unified
    mentions experience. Typing `@...` now searches across filesystem
    matches, installed plugins, and skills in one popup, with result types
    clearly labeled and selectable from the same flow.
    
    - Adds a unified `@mentions` popup that returns:
      - plugins
      - skills
      - files
      - directories
    
    - Adds search modes so users can narrow the popup without changing their
    query:
      - All Results _(default/same as Codex App)_
      - Filesystem Only
      - Plugins _(...and skills)_
    
    - Preserves existing insertion behavior:
      - selected file paths are inserted into the prompt
      - paths with spaces are quoted
      - image file selections still attach as images when possible
      - selecting a plugin or skill inserts the corresponding `$name`
    - the composer records the canonical mention binding, such as
    `plugin://...` or the skill path
    
    - Expanded `@mentions` rendering:
      - type tags for Plugin, Skill, File, and Dir
      - distinct plugin/filesystem colors
      - stable fixed-height layout (8 rows)
      - truncation behavior for narrow terminals
    
    Note:
    - The unified mentions popup does not display app connectors under
    `@mention` results for Codex App parity. Connector mentions remain
    available through the existing `$mention` path.

  • Fix goal update and add /goal edit command in TUI (#21954)
    ## Why
    
    Users have requested the ability to edit a goal's objective after a goal
    has been created. This PR exposes a new `/goal edit` command in the TUI
    to address this request.
    
    In the process of implementing this, I also noticed an existing bug in
    the goal runtime. When a goal's objective is updated through the
    `thread/goal/set` app server API, the goal runtime didn't emit a new
    steering prompt to tell the agent about the new objective. This PR also
    fixes this hole.
    
    ## What Changed
    
    - Adds `/goal edit` in the TUI, opening an edit box prefilled with the
    current goal objective.
    - Keeps active and paused goals in their current state, resets completed
    goals to active, keeps budget-limited goals budget-limited, and
    preserves the existing token budget.
    - Changes the existing `thread/goal/set` behavior so editing an
    objective preserves goal accounting instead of resetting it. The older
    reset-on-new-objective behavior was left over from before
    `thread/goal/clear`; clients that need to reset accounting can now clear
    the existing goal and create a new one.
    - Reuses the existing goal set API path; this does not add or change
    app-server protocol surface area.
    - Adds a dedicated goal runtime steering prompt when an externally
    persisted goal mutation changes the objective, so active turns receive
    the updated objective.
    
    ## Validation
    
    - Make sure `/goal edit` returns an error if no goal currently exists
    - Make sure `/goal edit` displays an edit box that can be optionally
    canceled with no side effects
    - Make sure that an edited goal results in a steer so the agent starts
    pursuing the new objective
    - Make sure the new objective is reflected in the goal if you use
    `/goal` to display the goal summary
    - Make sure that `/goal edit` doesn't reset the token budget, time/token
    accounting on the updated goal
  • app-server: remove TCP websocket listener (#21843)
    ## Why
    
    The app-server no longer needs to expose a TCP websocket listener.
    Keeping that transport also kept around a separate listener/auth surface
    that is unnecessary now that local clients can use stdio or the
    Unix-domain control socket, while remote connectivity is handled by
    `remote_control`.
    
    ## What Changed
    
    - Removed `ws://IP:PORT` parsing and the `AppServerTransport::WebSocket`
    startup path.
    - Deleted the app-server websocket listener auth module and removed
    related CLI flags/dependencies.
    - Kept websocket framing only where it is still needed: over the
    Unix-domain control socket and in the outbound `remote_control`
    connection.
    - Updated app-server CLI/help text and `app-server/README.md` to
    document only `stdio://`, `unix://`, `unix://PATH`, and `off` for local
    transports.
    - Converted affected app-server integration coverage from TCP websocket
    listeners to UDS-backed websocket connections, and added a parse test
    that rejects `ws://` listen URLs.
    - Removed the now-unused workspace `constant_time_eq` dependency and
    refreshed `Cargo.lock` after `cargo shear` caught the drift.
    - Moved test app-server UDS socket paths to short Unix temp paths so
    macOS Bazel test sandboxes do not exceed Unix socket path limits.
    
    ## Verification
    
    - Added/updated tests around UDS websocket transport behavior and
    `ws://` listen URL rejection.
    - `cargo shear`
    - `cargo metadata --no-deps --format-version 1`
    - `cargo test -p codex-app-server unix_socket_transport`
    - `cargo test -p codex-app-server unix_socket_disconnect`
    - `just fix -p codex-app-server`
    - `git diff --check`
    
    Local full Rust test execution was blocked before compilation by an
    external fetch failure for the pinned `nornagon/crossterm` git
    dependency. `just bazel-lock-update` and `just bazel-lock-check` were
    retried after the manifest cleanup but remain blocked by external
    BuildBuddy/V8 fetch timeouts.
  • Read cached metadata for installed Git plugins (#20825)
    ## Summary
    - Populate `plugin/list` interface metadata for installed Git-sourced

  • Reapply "Move skills watcher to app-server" (#21652)
    ## Why
    
    PR #21460 reverted the earlier move of skills change watching from
    `codex-core` into app-server. This reapplies that boundary change so
    app-server owns client-facing `skills/changed` notifications and core no
    longer carries the watcher.
    
    ## What
    
    - Restore the app-server `SkillsWatcher` and register it from thread
    listener setup.
    - Remove the core-owned skills watcher and its core live-reload
    integration surface.
    - Restore app-server coverage for `skills/changed` notifications after a
    watched skill file changes.
    
    ## Validation
    
    - `cargo test -p codex-app-server --test all

  • app-server: support daemon-safe restart handling (#21831)
    ## Why
    
    The app-server daemon work needs two app-server behaviors to be safe
    when lifecycle management is driven by a helper process:
    
    - a readiness probe must not become the process-wide client identity
    just because it connects first
    - a graceful reload signal needs to keep draining active turns even if
    it is delivered more than once
    
    ## What changed
    
    - Treat `codex_app_server_daemon` initialization as a probe-only client
    for process-global originator and user-agent suffix state.
    - Distinguish forceable shutdown signals from graceful-only ones, and
    treat Unix `SIGHUP` as graceful-only while leaving `SIGTERM` and Ctrl-C
    forceable.
    - Add regression coverage for daemon probe initialization and repeated
    `SIGHUP` delivery while a turn is still running.
    
    ## Testing
    
    - `cargo test -p codex-app-server`
      - The new daemon-probe and repeated-`SIGHUP` coverage passed.
    - The run still failed in the existing
    `suite::conversation_summary::get_conversation_summary_by_relative_rollout_path_resolves_from_codex_home`
    and
    `suite::conversation_summary::get_conversation_summary_by_thread_id_reads_rollout`
    tests because their initialize handshake timed out.
    - `cargo test -p codex-app-server --test all
    suite::conversation_summary::`
    - Reproduced the same two existing initialize-timeout failures in
    isolation.

  • [codex] request desktop attestation from app (#20619)
    ## Summary
    
    TL;DR: teaches `codex-rs` / app-server to request a desktop-provided
    attestation token and attach it as `x-oai-attestation` on the scoped
    ChatGPT Codex request paths.
    
    ![DeviceCheck attestation
    interface](https://raw.githubusercontent.com/openai/codex/dev/jm/devicecheck-diagram-assets/pr-assets/devicecheck-attestation-interface.png)
    
    ## Details
    
    This PR teaches the Codex app-server runtime how to request and attach
    an attestation token. It does not generate DeviceCheck tokens directly;
    instead, it relies on the connected desktop app to advertise that it can
    generate attestation and then asks that app for a fresh header value
    when needed.
    
    The flow is:
    
    1. The Codex desktop app connects to app-server.
    2. During `initialize`, the app can advertise that it supports
    `requestAttestation`.
    3. Before app-server calls selected ChatGPT Codex endpoints, it sends
    the internal server request `attestation/generate` to the app.
    4. app-server receives a pre-encoded header value back.
    5. app-server forwards that value as `x-oai-attestation` on the scoped
    outbound requests.
    
    The code in this repo is mostly protocol and runtime plumbing: it adds
    the app-server request/response shape, introduces an attestation
    provider in core, wires that provider into Responses / compaction /
    realtime setup paths, and covers the intended scoping with tests. The
    signed macOS DeviceCheck generation remains owned by the desktop app PR.

    First validated the signed desktop app boundary directly: launched a
    packaged signed `Codex.app`, sent `attestation/generate`, decoded the
    returned `v1.` attestation header, and validated the extracted
    DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using
    bundle ID `com.openai.codex`. Apple returned `status_code: 200` and
    `is_ok: true`.
    
    Then ran the fuller app + app-server flow. The packaged `Codex.app`
    launched a current-branch app-server via `CODEX_CLI_PATH`, and a local
    MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server
    requested `attestation/generate` from the real Electron app process, and
    the intercepted `/backend-api/codex/responses` traffic included
    `x-oai-attestation` on both routes:
    
    ```text
    GET  /backend-api/codex/responses  Upgrade: websocket  x-oai-attestation: present
    POST /backend-api/codex/responses  Upgrade: none       x-oai-attestation: present
    ```
    
    The captured header decoded to a DeviceCheck token that also validated
    with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`,
    team `2DC432GLL2`).

  • [codex] Generalize service tier slash commands (#21745)
    ## Why
    
    `/fast` was wired as a one-off slash command even though model metadata
    now exposes service tiers as catalog data. That meant adding another
    tier, such as a slower/cheaper tier, would require more hardcoded TUI
    plumbing instead of letting the model catalog drive the available
    commands.
    
    This change makes service-tier commands data-driven: each advertised
    `service_tiers` entry becomes a `/name` command using the catalog
    description, while the request path sends the tier `id` only when the
    selected model supports it.
    
    ## What Changed
    
    - Removed the hardcoded `/fast` slash-command variant and introduced
    dynamic service-tier command items in the composer and command popup.
    - Added toggle behavior for service-tier commands: invoking `/name`
    selects that tier, and invoking it again clears the selection.
    - Preserved the existing Fast-mode keybinding/status affordances by
    resolving the current model tier whose name is `fast`, while still
    sending the tier request value such as `priority`.
    - Persisted service-tier selections as raw request strings so non-fast
    tiers can round-trip through config.
    - Updated the Bedrock catalog entry to advertise fast support through
    `service_tiers` with `id: "priority"` and `name: "fast"`.
    - Added defensive filtering in core so unsupported selected service
    tiers are omitted from `/responses` requests.
    
    ## Validation
    
    - Added/updated coverage for dynamic service-tier slash command lookup,
    popup descriptions, composer dispatch, TUI fast toggling, and
    unsupported-tier omission in core request construction.
    - Local tests were not run per request.

  • Remove skills list extra roots (#21485)
    ## Summary
    - Remove `perCwdExtraUserRoots` / `SkillsListExtraRootsForCwd` from the
    `skills/list` app-server API.
    - Drop Rust app-server and `codex-core-skills` extra-root plumbing so
    skill scans are keyed by the normal cwd/user/plugin roots only.
    - Regenerate app-server schemas and update docs/tests that only existed
    for the removed extra-roots behavior.
    
    ## Validation
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core-skills`
    - `just fix -p codex-app-server-protocol`
    - `just fix -p codex-core-skills`
    - `just fix -p codex-app-server`
    - `just fix -p codex-tui`
    
    ## Notes
    - `cargo test -p codex-app-server --test all skills_list` ran the edited
    skills-list cases, but the full filtered run ended on existing
    `skills_changed_notification_is_emitted_after_skill_change` timeout
    after a websocket `401`.
    - `cargo test -p codex-tui --lib` compiled the changed TUI callers, then
    failed two unrelated status permission tests because local
    `/etc/codex/requirements.toml` forbids `DangerFullAccess`.
    - Source-truth check found the OpenAI monorepo still has
    generated/app-server-kit mirror references to the removed field; those
    should be cleaned up when generated app-server types are synced or in a
    companion OpenAI cleanup.
  • [codex] Remove remote thread store implementation (#21596)
    Remove the remote thread-store backend and checked-in protobuf

    crate's main entrypoint.
  • feat(app-server, threadstore): Thread pagination APIs and ThreadStore contract (#21566)
    ## Why
    The goal of this PR is to align on app-server and `ThreadStore` API
    updates for paginating through large threads.
    
    
    #### app-server
    ##### `thread/turns/list`
    - Updates `thread/turns/list` to support `itemsView?: "notLoaded" |
    "summary" | "full" | null`, defaulting to `summary`.
    - Implements the current `thread/turns/list` behavior over the existing
    persisted rollout-history fallback:
      - `notLoaded` returns turn envelopes with empty `items`.
    - `summary` returns the first user message and final assistant message
    when available.
      - `full` preserves the existing full item behavior.
    
    Note that this method still uses the naive approach of loading the
    entire rollout file, and returns just the filtered slice of the data.
    Real pagination will come later by leveraging SQLite.
    
    ##### `thread/turns/items/list`
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    
    #### ThreadStore
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    - Adds `ThreadStore` contract types and stubbed methods for listing
    thread turns and listing items within a turn.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    
    This also sketches the storage abstraction we expect to need once turns
    are indexed/stored. In particular, `notLoaded` is useful only if
    ThreadStore can eventually list turn metadata without loading every
    persisted item for each turn.
    
    ## Validation
    
    - Added/updated protocol serialization coverage for the new request and
    response shapes.
    - Added app-server integration coverage for `thread/turns/list` default
    summary behavior and all three `itemsView` modes.
    - Added app-server integration coverage that `thread/turns/items/list`
    returns the expected unsupported JSON-RPC error when experimental APIs
    are enabled.
    - Added thread-store coverage that the default trait methods return
    `ThreadStoreError::Unsupported`.
    
    No developers.openai.com documentation update is needed for this
    internal experimental app-server API surface.
  • Disable empty Cargo test targets (#21584)
    ## Summary
    
    `cargo test` has entails both running standard Rust tests and doctests.
    It turns out that the doctest discovery is fairly slow, and it's a cost

    This PR disables doctests with `doctest = false` for crates that lack
    any doctests.

  • [codex] Fix pathless thread summaries (#21266)
    ## Summary
    
    Fix `getConversationSummary` so thread-id summaries work for stored
    threads that do not have a local rollout path, such as remote thread
    stores.
    
    The root cause was that `summary_from_stored_thread` returned `None`
    when `StoredThread.rollout_path` was absent, and
    `get_thread_summary_response_inner` treated that as an internal error.
    This made conversation-id lookups depend on a local-only field even
    though the thread store can address the thread by id.
  • feat: Expose plugin share metadata in shareContext (#21495)
    Extends PluginSummary.shareContext with shareUrl and reader shareTargets
  • Show plugin hooks in plugin details (#21447)
    Supersedes the abandoned #19859, rebuilt on latest `main`.
    
    # Why
    
    PR #19705 adds discovery for hooks bundled with plugins, but `/plugins`
    still only shows skills, apps, and MCP servers. This follow-up makes
    bundled hooks visible in the same plugin detail view so users can
    inspect the full plugin surface in one place.
    
    We also need `PluginHookSummary` to populate Plugin Hooks in the app;
    `hooks/list` is not enough there because plugin detail needs to show
    hooks for disabled plugins too.
    
    # What
    
    - extend `plugin/read` with `PluginHookSummary` entries for bundled
    hooks
    - summarize plugin hooks while loading plugin details
    - render a `Hooks` row in the `/plugins` detail popup

  • Revert state DB injection and agent graph store (#21481)
    ## Why
    
    Reverts #20689 to restore the previous optional state DB plumbing. The
    conflict resolution keeps the newer installation ID and session/thread
    identity changes that landed after #20689, while removing the mandatory
    state DB and agent graph store dependency from ThreadManager
    construction.
    
    ## What changed
    
    - Restored `Option<StateDbHandle>` through app-server, MCP server,
    prompt debug, and test entry points.
    - Removed the `codex-core` dependency on `codex-agent-graph-store` and
    reverted descendant lookup back to the existing state DB path when
    available.
    - Kept newer `installation_id` forwarding by passing it beside the
    optional DB handle.
    - Kept local thread-name updates working when the optional state DB
    handle is absent.
    
    ## Validation
    
    - `git diff --check`
    - `cargo test -p codex-thread-store`
    - `cargo test -p codex-state -p codex-rollout -p

  • [codex] Parallelize skills list cwd loading (#21441)
    ## Summary
    - process `skills/list` cwd entries with bounded concurrency of 5
    - preserve the caller's requested cwd order in the response
    - add coverage that verifies response ordering remains stable
    
    ## Why
    Cold-start desktop traces showed that `skills/list` can dominate the
    shared config queue when it scans many workspace roots serially. The
    expensive work is largely independent per cwd, so the request was paying
    the sum of all cwd costs instead of the cost of the slowest bounded
    batch.
    
    ## Impact
    This keeps current request semantics intact while reducing the
    wall-clock time of large multi-root `skills/list` calls. That should
    also reduce how long later config-family requests, such as
    `plugin/list`, wait behind `skills/list` during startup.
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server`
    - `cargo test -p codex-app-server
    skills_list_preserves_requested_cwd_order`
  • feat: Add marketplace source filtering and plugin share context (#21419)
    Adds marketplaceKinds to plugin/list for local, workspace-directory, and
    shared-with-me; omitted params keep default local plus gated global
    behavior, while explicit kinds are exact.
    
    Exposes shareContext on plugin summaries from local share mappings and
    remote workspace/shared responses, including remotePluginId and nullable
    creator metadata.
    
    Adds shared-with-me listing through /ps/plugins/workspace/shared,
    renames the workspace remote namespace to workspace-directory, and keeps
    direct remote read/share/install/update/delete paths gated by plugins
    rather than remote_plugin.
  • Move skills watcher to app-server (#21287)
    ## Why
    
    Skills update notifications are app-server API behavior, but the watcher
    lived in `codex-core` and surfaced through
    `EventMsg::SkillsUpdateAvailable`. Moving the watcher out keeps core
    focused on thread execution and lets app-server own both cache
    invalidation and the `skills/changed` notification.
    
    ## What changed
    
    - Added an app-server-owned skills watcher that watches local skill
    roots, clears the shared skills cache, and emits `skills/changed`
    directly.
    - Registers skill watches from the common app-server thread listener
    attach path, including direct starts, resumes, and app-server-observed
    child or forked threads.
    - Stores the `WatchRegistration` on `ThreadState`, so listener
    replacement, thread teardown, idle unload, and app-server shutdown
    deregister by dropping the RAII guard.
    - Removed `EventMsg::SkillsUpdateAvailable`, the core watcher, and the
    old core live-reload test.
    - Extended the app-server skills change test to verify a cached skills
    list is refreshed after a filesystem change without forcing reload.
    
    ## Validation
    
    - `cargo check -p codex-core -p codex-app-server -p codex-mcp-server -p
    codex-rollout -p codex-rollout-trace`
    - `cargo test -p codex-app-server

  • 2- Use string service tiers in session protocol (#20971)
    ## Summary
    - break service tier session/op/app-server protocol fields from the
    closed enum to string tier ids
    - send the service tier string directly through model requests, prewarm,
    compaction, memories, and TUI/app-server turn starts
    - regenerate app-server protocol JSON/TypeScript schemas, removing the

  • feat(app-server): move v2 sessionId onto Thread (#21336)
    ## Why
    
    `session_id` and `thread_id` are separate identities after #20437, but
    app-server only surfaced `sessionId` on the `thread/start`,
    `thread/resume`, and `thread/fork` response envelopes. Other
    thread-bearing surfaces such as `thread/list`, `thread/read`,
    `thread/started`, `thread/rollback`, `thread/metadata/update`, and
    `thread/unarchive` either lacked the grouping key or forced clients to
    special-case those three responses.
    
    Making `sessionId` part of the reusable `Thread` payload gives every v2
    API surface one place to expose session-tree identity.
    
    ## Mental model
      1. thread.sessionId lives on `Thread`
    2. It is a view/runtime identity for the current live session tree, not
    durable stored lineage metadata
    3. When app-server has a live loaded thread, it copies the real value
    from core’s session_configured.session_id
    4. When it only has stored/unloaded data, it falls back to
    thread.sessionId = thread.id
    
    ## What changed
    
    - Added `sessionId` to the v2
    [`Thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server-protocol/src/protocol/v2/thread_data.rs#L105-L109).
    - Removed the duplicate top-level `sessionId` fields from
    `thread/start`, `thread/resume`, and `thread/fork`; clients should now
    read `response.thread.sessionId`.
    - Populated `thread.sessionId` when building live thread responses,
    replaying loaded threads, and returning stored-thread summaries so the
    field is present across start, resume, fork, list, read, rollback,
    metadata-update, unarchive, and `thread/started` paths. See
    [`load_thread_from_resume_source_or_send_internal`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L2824-L2918)
    and
    [`thread_from_stored_thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L3671-L3719).
    - Preserved the stored-thread fallback: if a thread has not been loaded
    into a live session tree yet, `thread.sessionId` falls back to
    `thread.id`; once the thread is live again, the field reports the active
    session tree root.
    - Regenerated the JSON/TypeScript schemas and updated the app-server
    README examples to show
    [`thread.sessionId`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/README.md#L306-L310)
    on the thread object.
  • feat: return session ID from thread/fork (#21332)
    ## Why
    
    `thread/start` and `thread/resume` already return `sessionId`, but
    `thread/fork` only returned the new thread. That left clients to infer
    the forked thread's session identity from `thread.id`, which kept the
    new `session_id` / `thread_id` split implicit at one lifecycle boundary.
    Follow-up to #20437.
    
    ## What changed
    
    - Add `sessionId` to `ThreadForkResponse`.
    - Populate it from the forked session configuration.
    - Regenerate the v2 JSON/TypeScript schema fixtures and update the
    app-server docs/example.
    - Extend the fork integration test to assert the returned `sessionId`.
    
    ## Verification
    
    - Added coverage in `thread_fork_creates_new_thread_and_emits_started`
    for the new response field.
  • feat: add session_id (#20437)
    ## Summary
    
    Related to
    https://openai.slack.com/archives/C095U48JNL9/p1777537279707449
    TLDR:
    We update the meaning of session ids and thread ids:
    * thread_id stays as now
    * session_id become a shared id between every thread under a /root
    thread (i.e. every sub-agent share the same session id)
    
    This PR introduces an explicit `SessionId` and threads it through the
    protocol/client boundary so `session_id` and `thread_id` can diverge
    when they need to, while preserving compatibility for older serialized
    `session_configured` events.

  • app-server: align dynamic tool identifiers with Responses API (#20724)
    ## Why
    
    Codex currently accepts dynamic tool names and namespaces that the
    upstream Responses function-tool path does not actually support. In
    practice, that means app-server can register a dynamic tool successfully
    and only discover later that the LLM-facing tool contract will reject or
    mishandle it.
    
    This PR tightens the app-server-side dynamic tool contract to match the
    Responses API before we stack dynamic tool hook support on top of it.
    
    ## What changed
    
    - validate dynamic tool `name` against the Responses function-tool
    identifier contract: `^[a-zA-Z0-9_-]+$`, length `1..128`
    - validate dynamic tool `namespace` the same way, with the Responses
    namespace length limit `1..64`
    - reject namespaces that collide with the always-reserved Responses
    runtime namespaces such as `functions`, `multi_tool_use`, `file_search`,
    `web`, `browser`, `image_gen`, `computer`, `container`, `terminal`,
    `python`, `python_user_visible`, `api_tool`, `tool_search`, and
    `submodel_delegator`
    - escape invalid identifiers in error messages so control characters do
    not spill raw into logs or client-visible error text
    - document the tightened dynamic tool identifier contract in
    `codex-rs/app-server/README.md`
    - add both unit coverage for the validator and an app-server integration
    test that rejects a `thread/start` request with Responses-incompatible
    dynamic tool identifiers
    
    ## Verification
    
    - `cargo test -p codex-app-server validate_dynamic_tools_`
    - `cargo test -p codex-app-server --test all
    thread_start_rejects_dynamic_tools_not_supported_by_responses`
