  • feat(remote-control): add pairing start (#25675)
    ## Why
    
    Remote control enrollment authorizes a desktop server, but app-server v2
    did not expose the follow-up pairing operation needed to mint a
    short-lived controller pairing artifact from that enrolled server.
    Clients need a narrow RPC that starts pairing without exposing the
    backend `serverId` or conflating pairing with websocket connection
    state.
    
    Issue: N/A; internal remote-control pairing API change.
    
    ## What Changed
    
    Added experimental app-server v2 `remoteControl/pairing/start` with
    `manualCode` input and `pairingCode`, nullable `manualPairingCode`,
    `environmentId`, and Unix-seconds `expiresAt` output. The method
    serializes under its own `global("remote-control-pairing")` scope and is
    documented in `app-server/README.md`.
    
    Extended the remote-control transport with private `/server/pair`
    request/response types and normalized `pair_url` handling. Pairing uses
    the current enrolled server bearer, refreshes that bearer when needed,
    keeps backend `server_id` private, validates returned `server_id` and
    `environment_id` against the current enrollment, and preserves backend
    status/header/body context for failures and malformed responses.
    
    Wired the request through `RemoteControlRequestProcessor` and
    `MessageProcessor`, mapping unavailable/disabled pairing to
    `invalid_request` and backend failures to internal errors.
    
    ## Verification

  • Add runtime extra skill roots API (#24977)
    ## Summary
    - Add v2 `skills/extraRoots/set` to replace app-server process-local
    standalone skill roots. The setting is not persisted, accepts missing
    roots, and `extraRoots: []` clears the runtime set.
    - Wire runtime roots into core skill discovery for `skills/list` and
    turn loads, clear skill caches on set, and register the roots with the
    skills watcher so later filesystem changes emit `skills/changed`.
    - Update app-server docs, generated JSON/TypeScript schemas, and
    coverage for serialization, missing roots, empty clears, and restart
    behavior.

  • standalone websearch extension (#23823)
    ## Summary
    
    Add the extension-backed standalone `web.run` tool so Codex can call the
    standalone search endpoint through the `codex-api` search client and
    return its encrypted output to Responses.
    
    - gate the new tool behind `standalone_web_search`
    - install the extension in the app-server thread registry and hide
    hosted `web_search` when standalone search is enabled for OpenAI
    providers so the two paths stay mutually exclusive
    - build search context from persisted history using a small tail
    heuristic: previous user message, assistant text between the last two
    user turns capped at about 1k tokens, and current user message
    
    ## Test Plan
    
    - `cargo test -p codex-web-search-extension`
    - `cargo test -p codex-api`
    - `cargo test -p codex-core

  • Wire app-server extension event sink (#24586)
    ## Why
    
    The goal extension already emits `ThreadGoalUpdated` events, but
    production app-server thread extensions were built with the default
    no-op extension event sink. That meant extension-driven goal updates
    could be produced without ever reaching app-server clients.
    
    ## What changed
    
    - Build app-server thread extensions with a host-provided
    `ExtensionEventSink`.
    - Add an app-server sink that converts extension `ThreadGoalUpdated`
    events into `ServerNotification::ThreadGoalUpdated` broadcasts.
    - Use the existing bounded outgoing message channel via `try_send` so
    event forwarding cannot create an unbounded queue.
    - Pass `NoopExtensionEventSink` in app-server tests that construct a
    `ThreadManager` without an app-server host.
    - Refresh `Cargo.lock` for the existing `codex-memories-extension`
    `codex-otel` dependency.
    
    ## Verification
    
    - `just test -p codex-app-server
    extensions::tests::app_server_event_sink_forwards_thread_goal_updates`
  • [codex] Add rollout-backed thread content search (#23519)
    ## Summary
    - add experimental `thread/search` for local rollout-backed thread
    search using `rg` over JSONL rollouts
    - return search-specific result rows with optional previews instead of
    storing preview data on `StoredThread` or ordinary `Thread` responses
    - keep `thread/list` separate from full-content search and document the
    new app-server surface
    
    ## Testing
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server
    thread_search_returns_content_and_title_matches -- --nocapture`
  • Add thread/settings/update app-server API (#23502)
    ## Why
    
    App-server clients need a way to update a thread's next-turn settings
    without starting a turn, adding transcript content, or waiting for turn
    lifecycle events. This gives settings UI a direct path for durable
    thread settings while clients observe the eventual effective state
    through a notification.
    
    This is a simplified rework of PR
    https://github.com/openai/codex/pull/22509. In particular, it changes
    the `thread/settings/update` api to return immediately rather than
    waiting and returning the effective (updated) thread settings. This
    makes the new api consistent with `turn/start` and greatly reduces the
    complexity of the implementation relative to the earlier attempt.
    
    ## What Changed
    
    - Adds experimental `thread/settings/update` with partial-update request
    fields and an empty acknowledgment response.
    - Adds experimental `thread/settings/updated`, carrying full effective
    `ThreadSettings` and scoped by `threadId` to subscribed clients for the
    affected thread.
    - Shares durable settings validation with `turn/start`, including
    `sandboxPolicy` plus `permissions` rejection and `serviceTier: null`
    clearing.
    - Emits the same settings notification when `turn/start` overrides
    change the stored effective thread settings.
    - Regenerates app-server protocol schema fixtures and updates
    `app-server/README.md`.
  • fix(app-server): speed up shutdown (#23578)
    ## Why
    
    Pressing `Ctrl+C` or `Ctrl+D` in the TUI could make Codex pause during
    shutdown when app-server background work still held outbound sender
    clones.
    
    Shutdown tracing against the current `~/.codex` path found three
    relevant holders:
    
    - `SkillsWatcher` kept its event-loop task alive until the shutdown
    timeout path.
    - `AppServerAttestationProvider` retained a strong
    `Arc<OutgoingMessageSender>`, which could keep outbound teardown waiting
    after the processor task had exited.
    - A background `apps/list` task could still own an outbound sender when
    shutdown began, causing the in-process app-server runtime to wait for
    its outbound channel to close.
    
    ## What Changed
    
    - Give `SkillsWatcher` an explicit shutdown `CancellationToken` and
    cancel it from app-server teardown so its event loop drops the outbound
    sender promptly.
    - Change `AppServerAttestationProvider` to keep a
    `Weak<OutgoingMessageSender>` and return immediately when it can no
    longer be upgraded.
    - Give `AppsRequestProcessor` a shutdown `CancellationToken` and cancel
    in-flight background `apps/list` work during teardown.
    
    ## How to Test
    
    1. Start Codex TUI from a real home configuration.
    2. Press `Ctrl+C`.
    3. Confirm Codex exits promptly instead of pausing during shutdown.
    4. Repeat with `Ctrl+D` and confirm the same prompt exit path.
    
    Focused manual trace validation from the investigation:
    
    - Before the full fix, reproduced shutdown traces showed outbound
    teardown waiting on lingering owners, including `attestation.provider=1`
    and later `apps.list.task=1`.
    - After the fix, fresh real-home `Ctrl+D` traces showed
    `app_server.runtime.outbound_state_after_processor_join` with
    `owners=none`, `app_server.runtime.wait_outbound_handle = 0ms`, and
    total TUI app-server shutdown around `18ms`.

  • feat: add permission profile list api (#23412)
    ## Why
    
    Clients need a typed permission-profile catalog instead of
    reconstructing that state from config internals.
    
    ## What changed
    
    - Added `permissionProfile/list` to the app-server v2 protocol with
    cursor pagination and optional `cwd`.
    - The list response includes built-in permission profiles plus
    config-defined `[permissions.<id>]` profiles from the effective config
    for the request context.
    - Permission profiles keep optional `description` metadata for display
    purposes.
    - App-server docs and schema fixtures are updated for the new RPC.
  • Route local-only app-server gating through processors (#23551)
    ## Summary
    - move local-only app-server gating out of `MessageProcessor`
    - let `fs/*`, `command/exec`, and `process/spawn` resolve local
    availability inside their owning processors
    - keep `fs/*` mounted for the future environment-param path while
    preserving current no-local error behavior
    
    ## Validation
    - not run locally per Codex repo guidance
  • Make local environment optional in EnvironmentManager (#23369)
    ## Summary
    - make `EnvironmentManager` local environment/runtime paths optional
    - simplify constructor surface around snapshot materialization
    - rename local env accessors to `require_local_environment` /
    `try_local_environment`
    
    ## Validation
    - devbox Bazel build for touched crate surfaces
    - `//codex-rs/exec-server:exec-server-unit-tests`
    - `//codex-rs/app-server-client:app-server-client-unit-tests`
    - filtered touched `//codex-rs/core:core-unit-tests` cases
  • [codex] Add installed-plugin mention API (#22448)
    ## Summary
    - add app-server `plugin/installed` for mention-oriented plugin loading
    - return installed plugins plus explicitly requested install-suggestion
    rows
    - keep remote handling on installed-state data instead of the broad
    catalog listing path
    
    ## Why
    The `@` mention surface only needs plugins that are usable now, plus a
    small product-approved set of install suggestions. It does not need the
    full catalog-shaped `plugin/list` payload that the Plugins page uses.
    
    ## Validation
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core-plugins`
    - `cargo test -p codex-app-server --test all plugin_installed_`
    
    ## Notes
    - The package-wide `cargo test -p codex-app-server` run still hits an
    existing unrelated stack overflow in
    `in_process::tests::in_process_start_clamps_zero_channel_capacity`.

  • app-server-protocol: remove PermissionProfile from API (#22924)
    ## Why
    
    The app server API should expose permission profile identity, not the
    lower-level runtime permission model. `PermissionProfile` is the
    compiled sandbox/network representation that the server uses internally;
    exposing it through app-server-protocol forces clients to understand
    details that should remain implementation-level.
    
    The API boundary should prefer `ActivePermissionProfile`: a stable
    profile id, plus future parent-profile metadata, that clients can pass
    back when they want to select the same active permissions. This also
    avoids schema generation collisions between the app-server v2 API type
    space and the core protocol model.
    
    Incidentally, while PR makes a number of changes to `command/exec`, note
    that we are hoping to deprecate this API in favor of `process/spawn`, so
    we don't need to be too finicky about these changes.
    
    ## What Changed
    
    - Removed `PermissionProfile` from the app-server-protocol API surface,
    including generated schema and TypeScript exports.
    - Changed `CommandExecParams.permissionProfile` to
    `ActivePermissionProfile`.
    - Resolve command exec profile ids through `ConfigManager` for the
    command cwd, matching turn override selection semantics.
    - Updated downstream TUI tests/helpers to use core permission types
    directly instead of app-server-protocol `PermissionProfile` shims.
  • feat(app-server): update remote control APIs for better UX (#22877)
    ## Why
    To help improve `codex remote-control` CLI UX which I plan to do in a
    followup, this PR adds `server-name` to the various remote control APIs:
    - `remoteControl/enable`
    - `remoteControl/disable`
    - `remoteControl/status/changed`
    
    Also, add a `remoteControl/status/read` API. This will be helpful in the
    Codex App.
  • 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.

  • mark Feature::RemoteControl as removed (#22386)
    ## Why
    
    `remote_control` can appear in `config.toml`, CLI feature overrides, and
    the app-server config APIs. Before this PR, app-server startup treated
    `config.features.enabled(Feature::RemoteControl)` as the signal to start
    remote control ([base
    code](https://github.com/openai/codex/blob/5e3ee5eddfa5333f2e0b011880abf0cbf92bd295/codex-rs/app-server/src/lib.rs#L678-L680)).
    That meant a user with:
    
    ```toml
    [features]
    remote_control = true
    ```
    
    would accidentally opt every app-server process into remote control.
    Remote-control startup should instead be a per-process launch decision
    made by CLI flags.
    
    ## What Changed
    
    - Marks `Feature::RemoteControl` as `Stage::Removed`, keeping
    `remote_control` as a known compatibility key while making it
    config-inert.
    - Adds a hidden `--remote-control` process flag to `codex app-server`
    and standalone `codex-app-server`.
    - Plumbs that flag through
    `AppServerRuntimeOptions.remote_control_enabled` and makes app-server
    startup use only that runtime option to decide whether to start remote
    control.
    - Removes the app-server config mutation hook that reloaded config and
    toggled remote control at runtime.
    - Updates managed daemon spawning to use `codex app-server
    --remote-control --listen unix://` instead of `--enable remote_control`.
    
    Config APIs can still list, read, write, and set `remote_control`; those
    operations just no longer affect remote-control process enrollment.

  • extension: wire extension registries into sessions (#21737)
    ## Why
    
    [#21736](https://github.com/openai/codex/pull/21736) introduces the
    typed extension API, but the runtime does not yet carry a registry
    through thread/session startup or give contributors host-owned stores to
    read from. This PR wires that host-side path so later feature migrations
    can move product-specific behavior behind typed contributions without
    adding another bespoke seam directly to `codex-core`.
    
    ## What changed
    
    - Thread `ExtensionRegistry<Config>` through `ThreadManager`,
    `CodexSpawnArgs`, `Session`, and sub-agent spawn paths.
    - Wire `ThreadStartContributor` and `ContextContributor`
    - Expose the small supporting surface needed by non-core callers that
    construct threads directly, including `empty_extension_registry()`
    through `codex-core-api`.
    
    This PR lands the host plumbing only: the app-server registry is still
    empty, and concrete feature migrations are intended to follow
    separately.
  • 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

  • [codex] support executor registry remote environments (#21323)
    ## Summary
    
    Support registry-backed remote executors end to end so downstream
    services can resolve an executor id into an exec-server URL and make
    that environment available to Codex without relying on the legacy cloud
    environments flow.
    
    ## What changed
    
    - switch remote executor registration to the executor registry bootstrap
    contract
    - allow named remote environments to be inserted into
    `EnvironmentManager` at runtime
    - add the experimental app-server RPC `environment/add` so initialized
    experimental clients can register those remote environments for later
    `thread/start` and `turn/start` selection
    
    ## Validation
    
    Ran focused validation locally:

  • [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

    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`).

  • 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.
  • 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] allow shared config reads in app-server queue (#21340)
    ## Summary
    - add a shared-read serialization mode for global app-server request
    families
    - let consecutive leading shared reads for the same family run together
    while keeping exclusive requests ordered
    - mark only `skills/list`, `config/read` and `plugin/list` as shared
    reads for now
    
    ## Why
    `skills/list` and `plugin/list` are read-only config-family requests,
    but the app-server queue currently treats every config request as
    exclusive. That means one long `skills/list` can make a later
    `plugin/list` wait even though the two requests do not mutate config.
    
    This change keeps the existing queue order but lets adjacent reads
    overlap. If a write is already waiting, later reads still stay behind
    it, so writes do not starve.
    
    ## Scope
    This intentionally keeps the first pass narrow:
    - shared reads: `skills/list`, `plugin/list`
    - still exclusive: `plugin/install`, `marketplace/*`,
    `skills/config/write`, `config/*write`, `config/read`, and the rest of
    the config family
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server`
    - `just fix -p codex-app-server-protocol`
    - `just fix -p codex-app-server`
    
    ## Desktop verification
    I ran the dev desktop app against this branch's built binary with the
    existing UI timing logs enabled. The app did use
    `/Users/xli/code/codex_6/codex-rs/target/debug/codex`.
    
    The new scheduler behavior works, but this narrow change does not remove
    every cold-start delay: in the observed trace, an earlier exclusive
    `config/read` was already queued ahead of the later `skills/list` and
    `plugin/list` requests, so the page-open plugin requests still waited
    behind that earlier exclusive config-family request before they could
    run together.
    
    That means this PR is the scheduler primitive needed for shared reads,
    not the complete end-to-end latency fix by itself.
    
    ## Not run
    - full workspace test suite, because repo policy requires explicit
    approval before running it after touching `app-server-protocol`
  • 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-analytics] emit tool item events from item lifecycle (#17090)
    ## Why
    
    After the tool-item schemas are in place, analytics needs to emit them
    from the app-server item lifecycle rather than requiring bespoke
    tracking at each callsite. The reducer should also reuse the shared
    thread analytics context introduced below it in the stack so later event
    families do not repeat the same reducer joins or missing-state ladder.
    
    ## What changed
    
    - Tracks tool-item completion notifications and emits the matching tool
    analytics event when a terminal item arrives.
    - Derives event-specific payload details for command execution, file
    changes, MCP calls, dynamic tools, collaboration tools, web search, and
    image generation.
    - Denormalizes thread, app-server client, runtime, and subagent
    provenance metadata through the shared thread analytics context.
    - Adds reducer coverage for item lifecycle emission and subagent
    metadata inheritance.
    
    ## Duration semantics
    
    `duration_ms` is computed from the app-server item lifecycle timestamps:
    `completed_at_ms - started_at_ms`. That makes it the duration of the
    lifecycle Codex observed locally, not necessarily the upstream
    provider's full execution time.
    
    - Web search usually has a meaningful observed lifecycle because
    Responses can send `response.output_item.added` before
    `response.output_item.done`; in that case `started_at_ms` comes from the
    added event and `completed_at_ms` comes from the done event.
    - Image generation can be much less precise. In the current observed
    stream, image generation often arrives only as a completed
    `response.output_item.done`; when there is no earlier added event, Codex
    synthesizes the started item immediately before completion, so
    `duration_ms` can be `0` even though upstream image generation took
    longer.
    - Standalone web search and standalone image generation work is expected
    to land after this stack. Those paths may introduce more direct
    lifecycle events or timing points, so the current
    web-search/image-generation duration semantics should be treated as the
    best available item-lifecycle approximation, not the final latency
    contract for those tool families.
    - `execution_duration_ms` is populated only where the completed item
    already carries a native execution duration; otherwise it remains `null`
    while `duration_ms` still reflects the local lifecycle interval.
    
    ## Currently placeholder / partial fields
    
    Some fields are included in the schema for the intended steady-state
    contract, but this PR does not yet populate them from real
    approval/review state:
    
    - `review_count`, `guardian_review_count`, and `user_review_count`
    currently default to `0`.
    - `final_approval_outcome` currently defaults to `unknown`.
    - `requested_additional_permissions` and `requested_network_access`
    currently default to `false`.
    
    ## Verification
    
    - `cargo test -p codex-analytics`

  • Move installation ID resolution out of core startup (#21182)
    ## Summary
    
    - resolve or inject the installation ID before core startup and pass it
    through `ThreadManager`, `CodexSpawnArgs`, and `Session` as a plain
    `String`
    - keep child sessions on the parent installation ID instead of
    rediscovering it inside core
    - propagate installation ID startup failures in `mcp-server` instead of
    panicking
    
    ## Why
    
    Core was still touching the filesystem on the session startup path to
    discover `installation_id`. This moves that work to the outer host
    boundary so core no longer depends on `codex_home` reads during session
    construction.

  • Preserve session MCP config on refresh (#21055)
    # Overview
    MCP refreshes were rebuilding active threads from fresh disk-backed
    config only, which dropped thread-start session overlays such as
    app-injected MCP servers. This keeps refreshes current with disk config
    while preserving the thread-local config that only the active thread
    knows about.
    
    # Changes
    - Rebuild refreshed config per active thread using that thread's current
    `cwd`, rather than fanning out one app-server config to every thread.
    - Preserve each thread's `SessionFlags` layer while replacing reloadable
    config layers with freshly loaded config, then derive the MCP refresh
    payload from the rebuilt result.
    - Move MCP refresh orchestration into app-server so manual refreshes
    fail loudly while background refreshes remain best-effort, and route
    plugin-triggered refreshes through the same per-thread reload path.
    - Add regression coverage for session overlays, fresh project config,
    plugin-derived MCP config, current requirements, and strict vs
    best-effort refresh behavior.
    
    # Verification
    - Passed focused Rust coverage for the thread-config rebuild behavior
    and deferred MCP refresh flow, plus `cargo test -p codex-app-server
    --lib`.
    - Verified end to end in the Codex dev app against the locally built
    CLI: registered an MCP via thread config, verified that it could be used
    successfully before refresh, manually triggered MCP refresh, and
    verified that it continued to be available afterward.
  • feat: Add plugin share access controls (#21124)
    Extends `plugin/share/save` to accept optional discoverability and
    shareTargets while uploading plugin contents, and adds
    `plugin/share/updateTargets` for share-only target updates without
    re-uploading.
  • Inject state DB, agent graph store (#20689)
    ## Why
    
    We want the agent graph store to be passed down the stack as a real
    dependency, the same way we already treat the thread store.
    
    This will let us inject the agent graph store as a real dependency and
    support implementations other than the local SQLite-backed one. Right
    now most code instantiates a state DB and an agent graph store
    just-in-time. Ideally, we would not depend on the state DB directly but
    only read through the higher-level interfaces.
    
    This change makes the dependency boundaries explicit and moves state DB
    initialization to process bootstrap instead of hiding it inside local
    store implementations.
    
    ## What changed
    
    - `ThreadManager` now requires a `StateDbHandle` and an
    `AgentGraphStore` at construction time instead of treating them as
    optional internals.
    - The local store constructors no longer lazily initialize SQLite.
    Callers now initialize the state DB once per process and use that shared
    handle to build:
      - `LocalThreadStore`
      - `LocalAgentGraphStore`
    - App bootstraps (`app-server`, `mcp-server`, `prompt_debug`, and the
    thread-manager sample) now initialize the state DB up front and inject
    the resulting handle down the stack.
    - `app-server` now consistently uses its process-scoped state DB handle
    instead of reopening SQLite or trying to recover it from loaded threads.
    - Device-key storage now reuses the shared state DB handle instead of
    maintaining its own lazy opener.
    - The thread archive / descendant traversal paths now use the injected
    `AgentGraphStore` instead of reaching through local
    thread-store-specific state.

  • Auto-deny MCP elicitations for Xcode 26.4 clients (#21113)
    ## Summary
    
    Xcode 26.4 was built against app-server behavior from before MCP
    elicitation requests became client-visible in CLI 0.120.0 via #17043.
    That client line does not expect the new events/messages, so this PR
    restores the old behavior for exactly that client/version combination.
    
    The compatibility handling stays in the app-server layer: when the
    initialized client is `Xcode` and its version starts with `26.4`, the
    app server marks the live Codex thread so MCP elicitations are
    auto-denied. The flag is applied on thread start/resume/fork/turn
    attachment, carried through `Codex`/`CodexThread`, and stored on
    `McpConnectionManager` so refreshed MCP managers preserve the behavior.
    
    ## Notes
    
    This is intentionally narrow and includes a TODO to remove the
    compatibility path once Xcode 26.4 ages out.
  • Add Windows sandbox readiness RPC (#20708)
    ## Why
    
    The desktop app on Windows needs a read-only way to tell, before the
    next tool call, whether the local Windows sandbox setup is in a state
    that should block the user and ask for setup again.
    
    The main case we want to cover is the elevated sandbox setup version
    bump. Today, if the app is configured for elevated Windows sandboxing
    and the installed setup is stale, the next sandboxed shell/exec path can
    end up triggering the elevated setup flow directly. That means the user
    can see an unexpected UAC prompt with no UI explanation.
    
    This change adds a small app-server preflight so the desktop app can ask
    “is Windows sandbox ready, not configured, or update-required?” during
    startup and show the appropriate blocking UI before the user hits a tool
    call.
    
    ## What changed
    
    - Added a new read-only app-server RPC: `windowsSandbox/readiness`
    - Added a new protocol enum and response type:
      - `WindowsSandboxReadiness`
      - `WindowsSandboxReadinessResponse`
    - Added core readiness logic in `core/src/windows_sandbox.rs`:
      - `ready`
      - `notConfigured`
      - `updateRequired`
    - Wired the new request through `codex_message_processor`
    - Regenerated the vendored app-server schema fixtures
    
    ## Readiness semantics
    
    This is intentionally a coarse startup/version-bump readiness check, not
    a full predictor of every runtime repair case.
    
    For now, readiness is determined from:
    - the configured Windows sandbox level
    - `sandbox_setup_is_complete()` for elevated mode
    
    That means:
    - `disabled` maps to `notConfigured`
    - `restricted token` maps to `ready`
    - `elevated` maps to `ready` or `updateRequired` depending on
    `sandbox_setup_is_complete()`
    
    This is deliberate for the first UI integration because the common case
    we want to catch is “the app updated, the elevated setup version bumped,
    and the user should see an update-required blocker instead of a surprise
    UAC prompt”.
    
    It does not attempt to model every case where the deeper runtime path
    might decide to repair or re-run setup.
    
    ## Testing
    
    - Ran `cargo fmt --all -- app-server-protocol/src/protocol/common.rs
    app-server-protocol/src/protocol/v2.rs
    app-server/src/codex_message_processor.rs core/src/windows_sandbox.rs

    - Added unit tests for the pure readiness mapping in

    - Regenerated vendored schema fixtures with `cargo run -p
    codex-app-server-protocol --bin write_schema_fixtures -- --schema-root
    app-server-protocol/schema`
    - Did not run the full cargo test suite
  • codex: migrate (more) app-server thread history reads to ThreadStore (#20575)
    Migrate token usage replay, rollback responses, and detached review
    setup (a special case of forking) to be served from ThreadStore reads
    rather direct rollout files.
    
    - replay restored token usage from already-loaded `RolloutItem` history
    instead of reopening `Thread.path`
    - rebuild rollback responses from loaded `ThreadStore` snapshots and
    history
    - start detached reviews from store-backed parent history and stored
    review-thread metadata
    - remove obsolete app-server rollout-summary helper code that became
    dead after the store-backed migration
    - preserve response/notification ordering for resume, fork, rollback,
    and detached review flows
    - add integration test coverage for the affected paths
  • [codex] Add unsandboxed process exec API (#19040)
    ## Why
    
    App-server clients sometimes need argv-based local process execution
    while sandbox policy is controlled outside Codex. Those environments can
    reject sandbox-disabling paths before a command ever starts, even when
    the caller intentionally wants unsandboxed execution.
    
    This PR adds a distinct `process/*` API for that use case instead of
    extending `command/exec` with another sandbox-disabling shape. Keeping
    the new surface separate also makes the future removal of `command/exec`
    simpler: clients that need explicit process lifecycle control can move
    to the newer handle-based API without depending on `command/exec`
    business logic.
    
    ## What changed
    
    - Added v2 process lifecycle methods: `process/spawn`,
    `process/writeStdin`, `process/resizePty`, and `process/kill`.
    - Added process notifications: `process/outputDelta` for streamed
    stdout/stderr chunks and `process/exited` for final exit status and
    buffered output.
    - Made `process/spawn` intentionally unsandboxed and omitted
    sandbox-selection fields such as `sandboxPolicy` and
    `permissionProfile`.
    - Added client-supplied, connection-scoped `processHandle` values for
    follow-up control requests and notification routing.
    - Supported cwd, environment overrides, PTY mode and size, stdin
    streaming, stdout/stderr streaming, per-stream output caps, and timeout
    controls.
    - Killed active process sessions when the originating app-server
    connection closes.
    - Wired the implementation through the modular `request_processors/`
    app-server layout, with process-handle request serialization for
    follow-up control calls.
    - Updated generated JSON/TypeScript schema fixtures and documented the
    new API in `codex-rs/app-server/README.md`.
    - Added v2 app-server integration coverage in
    `codex-rs/app-server/tests/suite/v2/process_exec.rs` for spawn
    acknowledgement before exit, buffered output caps, and process
    termination.

  • state: pass state db handles through consumers (#20561)
    ## Why
    
    SQLite state was still being opened from consumer paths, including lazy
    `OnceCell`-backed thread-store call sites. That let one process
    construct multiple state DB connections for the same Codex home, which
    makes SQLite lock contention and `database is locked` failures much
    easier to hit.
    
    State DB lifetime should be chosen by main-like entrypoints and tests,
    then passed through explicitly. Consumers should use the supplied
    `Option<StateDbHandle>` or `StateDbHandle` and keep their existing
    filesystem fallback or error behavior when no handle is available.
    
    The startup path also needs to keep the rollout crate in charge of
    SQLite state initialization. Opening `codex_state::StateRuntime`
    directly bypasses rollout metadata backfill, so entrypoints should
    initialize through `codex_rollout::state_db` and receive a handle only
    after required rollout backfills have completed.
    
    ## What Changed
    
    - Initialize the state DB in main-like entrypoints for CLI, TUI,
    app-server, exec, MCP server, and the thread-manager sample.
    - Pass `Option<StateDbHandle>` through `ThreadManager`,
    `LocalThreadStore`, app-server processors, TUI app wiring, rollout
    listing/recording, personality migration, shell snapshot cleanup,
    session-name lookup, and memory/device-key consumers.
    - Remove the lazy local state DB wrapper from the thread store so
    non-test consumers use only the supplied handle or their existing
    fallback path.
    - Make `codex_rollout::state_db::init` the local state startup path: it
    opens/migrates SQLite, runs rollout metadata backfill when needed, waits
    for concurrent backfill workers up to a bounded timeout, verifies
    completion, and then returns the initialized handle.
    - Keep optional/non-owning SQLite helpers, such as remote TUI local
    reads, as open-only paths that do not run startup backfill.
    - Switch app-server startup from direct
    `codex_state::StateRuntime::init` to the rollout state initializer so
    app-server cannot skip rollout backfill.
    - Collapse split rollout lookup/list APIs so callers use the normal
    methods with an optional state handle instead of `_with_state_db`
    variants.
    - Restore `getConversationSummary(ThreadId)` to delegate through
    `ThreadStore::read_thread` instead of a LocalThreadStore-specific
    rollout path special case.
    - Keep DB-backed rollout path lookup keyed on the DB row and file
    existence, without imposing the filesystem filename convention on
    existing DB rows.
    - Verify readable DB-backed rollout paths against `session_meta.id`
    before returning them, so a stale SQLite row that points at another
    thread's JSONL falls back to filesystem search and read-repairs the DB
    row.
    - Keep `debug prompt-input` filesystem-only so a one-off debug command
    does not initialize or backfill SQLite state just to print prompt input.
    - Keep goal-session test Codex homes alive only in the goal-specific
    helper, rather than leaking tempdirs from the shared session test
    helper.
    - Update tests and call sites to pass explicit state handles where DB
    behavior is expected and explicit `None` where filesystem-only behavior
    is intended.

    Focused coverage added in `codex-rollout`:
    
    - `recorder::tests::state_db_init_backfills_before_returning` verifies
    the rollout metadata row exists before startup init returns.
    - `state_db::tests::try_init_waits_for_concurrent_startup_backfill`
    verifies startup waits for another worker to finish backfill instead of
    disabling the handle for the process.
    -
    `state_db::tests::try_init_times_out_waiting_for_stuck_startup_backfill`
    verifies startup does not hang indefinitely on a stuck backfill lease.
    -
    `tests::find_thread_path_accepts_existing_state_db_path_without_canonical_filename`
    verifies DB-backed lookup accepts valid existing rollout paths even when
    the filename does not include the thread UUID.
    -
    `tests::find_thread_path_falls_back_when_db_path_points_to_another_thread`
    verifies DB-backed lookup ignores a stale row whose existing path
    belongs to another thread and read-repairs the row after filesystem
    fallback.
    
    Focused coverage updated in `codex-core`:
    
    - `rollout_list_find::find_prefers_sqlite_path_by_id` now uses a
    DB-preferred rollout file with matching `session_meta.id`, so it still
    verifies that valid SQLite paths win without depending on stale/empty
    rollout contents.
    
    `cargo test -p codex-app-server thread_list_respects_search_term_filter
    -- --test-threads=1 --nocapture` was attempted locally but timed out
    waiting for the app-server test harness `initialize` response before
    reaching the changed thread-list code path.
    
    `bazel test //codex-rs/thread-store:thread-store-unit-tests
    --test_output=errors` was attempted locally after the thread-store fix,
    but this container failed before target analysis while fetching `v8+`
    through BuildBuddy/direct GitHub. The equivalent local crate coverage,
    including `cargo test -p codex-thread-store`, passes.
    
    A plain local `cargo check -p codex-rollout -p codex-app-server --tests`
    also requires system `libcap.pc` for `codex-linux-sandbox`; the
    follow-up app-server check above used `CODEX_SKIP_VENDORED_BWRAP=1` in
    this container.
  • [codex] Split app-server request processors (#20940)
    ## Why
    
    The app-server request path had grown around a large
    `CodexMessageProcessor` plus separate API wrapper/helper modules. That
    made the dependency graph hard to see and forced unrelated request
    families to share broad processor state.
    
    This PR makes the split mechanical and command-prefix oriented so
    request families own only the dependencies they use.
    
    ## What changed
    
    - Replaced `CodexMessageProcessor` with command-prefix request
    processors under `app-server/src/request_processors/`.
    - Removed the old config, device-key, external-agent-config, and fs API
    wrapper files by moving their API handling into processors.
    - Split apps, plugins, marketplace, catalog, account, MCP, command exec,
    fs, git, feedback, thread, turn, thread goals, and Windows sandbox
    handling into dedicated processors.
    - Kept shared lifecycle, summary conversion, token usage replay, and
    shared error mapping only where multiple processors use them; single-use
    helpers were inlined into their owning processor.
    - Removed the fallback processor path and moved processor tests to
    `_tests` files.
    
    ## Validation
    
    - `cargo test -p codex-app-server`
    - `cargo check -p codex-app-server`
    - `just fix -p codex-app-server`
  • [codex] Refactor app-server dispatch result flow (#20897)
    ## Why
    
    App-server request handling had response sending spread across many
    individual handlers, which made it harder to see which requests return
    payloads, which methods send their own delayed response, and which
    branches emit notifications after a response.
    
    ## What changed
    
    - Centralized normal `ClientResponsePayload` sending in the dispatch
    path.
    - Kept explicit-response methods explicit where they need custom
    ordering or delayed delivery.
    - Removed forward-only handler wrappers and immediate `async { ...
    }.await` bodies where they were not needed.
    - Moved branch-specific post-response notifications into the branches
    that own the response ordering.
    - Replaced unreachable delegated request-family error arms with explicit
    `unreachable!` cases.
    
    ## Verification
    
    - `cargo check -p codex-app-server`
    - `cargo test -p codex-app-server thread_goal`
    - `just fix -p codex-app-server`
  • Make thread store process-scoped (#19474)
    - Build one app-server process ThreadStore from startup config and share
    it with ThreadManager and CodexMessageProcessor.
    - Remove per-thread/fork store reconstruction so effective thread config
    cannot switch the persistence backend.
    - Add params to ThreadStore create/resume for specifying thread
    metadata, since otherwise the metadata from store creation would be used
    (incorrectly).
  • Reduce the surface of collaboration modes (#20149)
    Collaboration modes were slightly invasive both into ThreadManager
    construction and ModelProvider
  • Import external agent sessions in background (#20284)
    Summary:
    - Return from external agent import before session history import
    finishes
    - Run session import work in the background and emit the existing
    completion notification when it is done
    - Serialize session imports so duplicate requests do not create
    duplicate imported threads

  • [app-server] type client response payloads (#20050)
    ## Why
    
    `pr17088` adds typed server-originated request/response plumbing, but
    successful client responses are still erased into bare JSON-RPC `result`
    values before app-server can make any typed decision about them.
    
    This precursor PR keeps successful client responses typed until the
    outgoing response seam. It is intentionally limited to
    protocol/app-server plumbing so the analytics behavior change can review
    separately on top.
    
    ## What changed
    
    - Add `ClientResponsePayload` as the pre-serialization client response
    body type.
    - Route app-server successful response paths through the typed payload
    seam while preserving existing handler-local analytics behavior.
    - Keep `InterruptConversation` JSON-RPC-only because it has no
    `ClientResponse` variant.
    - Move the new payload conversion tests into a dedicated protocol test
    module.
    
    ## Verification
    
    - `cargo check -p codex-app-server`
    - `cargo test -p codex-app-server-protocol`
  • [codex-analytics] ingest server requests and responses (#17088)
    ## Why
    
    Codex analytics needs a typed seam for app-server-originated
    request/response traffic so future tool-approval analytics can consume
    those facts without adding bespoke callsite tracking each time. Server
    responses arrive as JSON-RPC `id + result` payloads, so analytics has to
    reconstruct the matching typed response from the original typed request
    while that request context still exists in app-server.
    
    This also puts analytics on the app-server outbound path, which needs to
    avoid keeping the runtime alive during shutdown. The final ownership fix
    keeps the normal strong auth-manager retention in analytics and makes
    the external-auth refresh bridge hold a weak back-reference to
    `OutgoingMessageSender`, breaking the runtime cycle at the bridge
    boundary instead of exposing retention policy through the analytics
    client API.
    
    ## What changed
    
    - Adds typed `ServerRequest` and `ServerResponse` analytics facts, plus
    `AnalyticsEventsClient::track_server_request` and
    `track_server_response`.
    - Renames the existing client-side facts to `ClientRequest` and
    `ClientResponse` so reducers can distinguish client-to-server traffic
    from server-to-client traffic.
    - Adds `ServerRequest::response_from_result`, allowing a stored typed
    request to decode the matching typed server response from a raw JSON-RPC
    result payload.
    - Threads `AnalyticsEventsClient` through `OutgoingMessageSender` and
    records targeted server requests, replayed targeted requests, and
    matching targeted responses with the responding connection id needed for
    correlation.
    - Intentionally leaves broadcast server requests/responses out of
    analytics for now because the current model is per connection, while
    broadcasts fan one logical request out across multiple connections.
    - Breaks the app-server shutdown cycle by storing
    `Weak<OutgoingMessageSender>` in `ExternalAuthRefreshBridge` and
    upgrading it only when an external-auth refresh is actually requested.
    - Keeps reducer ingestion of the new server-side facts as no-ops for
    now; this PR is plumbing for later tool-approval analytics work.
    
    ## Verification
    
    - `cargo test -p codex-analytics`
    - `cargo test -p codex-app-server outgoing_message::tests::`
    - Covers typed-response reconstruction plus the targeted, replayed,
    broadcast-exclusion, and response-attribution analytics paths.
    
    ## Follow-up
    
    This PR intentionally stops at ingestion plumbing, so `ServerRequest`
    and `ServerResponse` facts are still reducer no-ops. Once a follow-up PR
    adds real downstream analytics output for those facts:
    
    - replace the temporary pre-reducer observation seam with reducer tests
    for the emitted event shape;
    - add end-to-end coverage in `app-server/tests/suite/v2/analytics.rs`
    for the real app-server workflow and captured analytics payload;
    - remove the temporary sender-level observer tests added here in favor
    of the real-output coverage above.

  • feat: Use remote installed plugin cache for skills and MCP (#20096)
    - Fetches and caches remote /installed plugin state
    - Lets skills/list load skills from remote-installed cached plugins
    without requiring a local marketplace entry
    - Routes plugin list/startup/install/uninstall changes through async
    plugin cache invalidation and MCP refresh
  • feat: expose provider capability bounds to app server clients (#20049)
    follow up of #19442. The app server now exposes provider-derived bounds
    through a new v2 `modelProvider/read` method. The response reports the
    configured provider map key as `modelProvider` and returns the effective
    capability booleans so clients can align their UI with the same
    provider-owned limits used by core.
