  • [codex] add roles to realtime append text (#27936)
    ## Summary
    
    Add an explicit `user` or `developer` role to
    `thread/realtime/appendText` and propagate it through the realtime input
    queue into `conversation.item.create`. Older JSON clients that omit the
    field continue to default to `user`.
    
    This lets app-provided context such as memory retain developer authority
    without bypassing app-server through a renderer-owned data channel. The
    app-server schemas, API documentation, and focused protocol and
    websocket coverage are updated with the new contract.
    
    The Codex Apps consumer is tracked in
    [openai/openai#1025261](https://github.com/openai/openai/pull/1025261).
  • Support plaintext agent messages (#27830)
    ## Why
    
    Multi-agent v2 `send_message` deliveries already reach the receiving
    model as typed `agent_message` items with encrypted content.
    Child-completion notifications are generated by Codex itself, so their
    content is plaintext and previously fell back to a serialized JSON
    envelope inside an assistant message.
    
    With plaintext `input_text` supported for `agent_message`, both delivery
    paths can use the same model-visible type while preserving explicit
    author and recipient metadata.
    
    ## What changed
    
    - add plaintext `input_text` support to `AgentMessageInputContent` and
    regenerate the affected app-server schemas
    - preserve `InterAgentCommunication` as structured mailbox input instead
    of converting it to assistant text
    - record delivered communications as typed `agent_message` history items
    - persist a dedicated rollout item so local delivery metadata such as
    `trigger_turn` remains available without leaking into the Responses
    request
    - reconstruct typed agent messages on resume and preserve fork-turn
    truncation behavior
    - remove request-time assistant-content parsing
    - preserve plaintext and encrypted inter-agent deliveries in stage-one
    memory inputs
    - normalize and link plaintext and encrypted agent messages in rollout
    traces without treating inbound messages as child results
    - cover the real MultiAgent V2 child-completion path end to end with
    deterministic mailbox synchronization

  • realtime: add AVAS architecture override (#27720)
    ## Summary
    
    Adds a `RealtimeConversationArchitecture` option for realtime
    conversation startup, with `realtimeapi` as the default and `avas` as an
    opt-in architecture.
    
    The AVAS path is limited to realtime v1 conversational WebRTC starts,
    and WebRTC call creation appends `intent=quicksilver&architecture=avas`
    to `/v1/realtime/calls`. The existing sideband websocket still joins by
    `call_id`.
    
    This also exposes the per-session architecture override through
    app-server v2 `thread/realtime/start` params and updates the config
    schema for `[realtime].architecture`.

  • feat(app-server): persist remote-control desired state (#27445)
    ## Why
    
    Remote-control runtime enablement and persisted enrollment preference
    were represented by separate flags. That made startup rehydration, RPC
    persistence, and new-enrollment seeding race with one another, and it
    did not cleanly distinguish runtime-only CLI or daemon starts from
    durable app-server RPC changes.
    
    ## What Changed
    
    - Replace the parallel enablement, seed, and rehydration flags with one
    transport-owned `RemoteControlDesiredState`.
    - Add nullable enrollment-scoped persistence and preserve existing
    preferences during enrollment upserts.
    - Rehydrate plain startup only after auth and client scope resolve,
    without overwriting a concurrent RPC transition.
    - Make ordinary `remoteControl/enable` and `remoteControl/disable`
    durable while retaining `ephemeral: true` for runtime-only callers.
    - Have the daemon explicitly request ephemeral enablement and regenerate
    the app-server schemas.
    
    ## Verification
    
    - Covered migration and `NULL`/`0`/`1` persistence round trips.
    - Covered plain-start rehydration and runtime-only versus durable
    enrollment seeding.
    - Covered durable enable, durable disable, and ephemeral enable through
    app-server RPC.
    - Covered the daemon's exact `{ "ephemeral": true }` request payload.
    
    Related issue: N/A (internal remote-control persistence architecture
    change).
  • Add app-server thread/delete API (#25018)
    ## Why
    
    Clients can archive and unarchive threads today, but there is no
    app-server API for permanently removing a thread. Deletion also needs to
    cover the full session tree: deleting a main thread should remove
    spawned subagent threads and the related local metadata instead of
    leaving orphaned rollout files, goals, or subagent state behind.
    
    ## What
    
    - Adds the v2 `thread/delete` request and `thread/deleted` notification,
    with the response shape kept consistent with `thread/archive`.
    - Implements local hard delete for active and archived rollout files.
    - Deletes the requested thread's state DB row as the commit point, then
    best-effort cleans associated state including spawned descendants,
    goals, spawn edges, logs, dynamic tools, and agent job assignments.
    - Updates app-server API docs and generated protocol schema/TypeScript
    fixtures.
  • Add per-session realtime model and version overrides (#24999)
    ## Why
    
    Clients need to select a realtime session configuration for an
    individual start without rewriting persisted configuration or restarting
    the app-server process.
    
    ## What Changed
    
    - Add optional `model` and `version` fields to `thread/realtime/start`
    - Forward those optional values through the realtime start operation and
    apply them only for that session
    - Preserve existing configured/default behavior when the new fields are
    omitted
    - Update generated protocol schema and app-server documentation
    
    ## Validation
    
    - Added/updated protocol serialization coverage for the new optional
    request fields
    - Added focused core coverage for a session override taking precedence
    over configured realtime selection
    - Added focused app-server coverage that a request override reaches the
    realtime WebSocket handshake
  • [codex-analytics] add extensible feature thread sources (#27063)
    ## Why
    - `ThreadSource` currently defines a closed set of core-owned values
    - Product features also create threads for background or scheduled work
    - Adding every product-specific value to the core enum would require
    repeated `codex-rs` protocol changes
    - Feature-backed values let product callers provide precise attribution
    while preserving the existing core classifications
    
    ## What Changed
    - Adds `ThreadSource::Feature(String)` for app-owned thread source
    values
    - Represents all app-server v2 thread sources as scalar strings, so a
    feature source is supplied as `"automation"`
    - Persists and emits the feature's plain string label, so `"automation"`
    produces `thread_source="automation"` in analytics
    - Keeps `user`, `subagent`, and `memory_consolidation` as explicit
    core-owned values and regenerates the app-server schemas and TypeScript
    bindings

  • Load selected executor skills through extensions (#27184)
    ## Why
    
    CCA is moving toward a split runtime where the orchestrator may not have
    a filesystem, while executors can expose preinstalled plugins and
    skills. A thread therefore needs to select capabilities without asking
    app-server or core to interpret executor-owned paths through the
    orchestrator's filesystem.
    
    The longer-term model is broader than executor skills:
    
    - A plugin is a bundle of skills, MCP servers, connectors/apps, and
    hooks.
    - A plugin root can be local, executor-owned, or hosted by a backend.
    - Components inside one plugin can use different access and execution
    mechanisms. A skill may be read from a filesystem or through backend
    tools; an HTTP MCP server can run without an executor; a stdio MCP
    server or hook needs an execution environment.
    - Core should carry generic extension initialization data. The extension
    that owns a component should discover it, expose it to the model, and
    invoke it through the appropriate runtime.
    
    This PR establishes that architecture through one complete vertical:
    selecting a root on an executor, discovering the skills beneath it,
    exposing those skills to the model, and reading an explicitly invoked
    `SKILL.md` through the same executor.
    
    ## Contract
    
    `thread/start` gains an experimental `selectedCapabilityRoots` field:
    
    ```json
    {
      "selectedCapabilityRoots": [
        {
          "id": "deploy-plugin@1",
          "location": {
            "type": "environment",
            "environmentId": "workspace",
            "path": "/opt/codex/plugins/deploy"
          }
        }
      ]
    }
    ```
    
    The root is intentionally not classified as a "plugin" or "skill" in the
    API. It can point at a standalone skill, a directory containing several
    skills, or a plugin containing skills and other components. This PR only
    teaches the skills extension how to consume it; later extensions can
    resolve MCP, connector, and hook components from the same selection.
    
    The platform-supplied `id` is stable selection identity. The location
    says which runtime owns the root and gives that runtime an opaque path.
    App-server does not inspect or canonicalize the path.
    
    ## What changed
    
    ### Generic thread extension initialization
    
    App-server converts selected roots into `ExtensionDataInit`. Core
    carries that generic initialization value until the final thread ID is
    known, then creates thread-scoped `ExtensionData` before lifecycle
    contributors run.
    
    This keeps `Session` and core independent of the capability-selection
    contract. The initialization value is consumed during construction; it
    is not retained as another long-lived `Session` field.
    
    ### Executor-backed skills
    
    The skills extension now owns an `ExecutorSkillProvider` that:
    
    - resolves the selected environment through `EnvironmentManager`
    - discovers, canonicalizes, and reads skills through that environment's
    `ExecutorFileSystem`
    - contributes the bounded selected-skill catalog as stable developer
    context
    - reads an explicitly invoked skill body through the authority that
    listed it
    - warns when an environment or root is unavailable
    - never falls back to the orchestrator filesystem for an executor-owned
    root
    
    Skill catalog and instruction fragments have hard byte bounds, which
    also bound them below the 10K-token per-item context limit. If a
    selected executor skill has the same name as a legacy local skill, the
    executor selection owns that invocation and the local body is not
    injected a second time.
    
    Existing local and bundled skill loading remains in place. Omitting
    `selectedCapabilityRoots` therefore preserves current local-only
    behavior.
    
    ## Current semantics
    
    - Only environment-owned locations are represented in this first
    contract.
    - Roots are resolved by the destination extension, not by app-server or
    core.
    - An unavailable executor or invalid root produces a warning and no
    capabilities from that root; it does not trigger a local-filesystem
    fallback.
    - Selection applies to a newly started active thread.
    - MCP servers, connectors, and hooks beneath a selected plugin root are
    not activated yet.
    - Selection is not yet persisted or inherited across resume, fork, or
    subagent creation. Existing local capabilities continue to behave as
    they do today in those flows.
    
    ## Planned vertical follow-ups
    
    1. **Hosted HTTP MCP:** add an extension-backed HTTP MCP source that
    works without an executor, then replace the special-purpose MCP plugins
    loader with that implementation.
    2. **Executor MCP:** register and execute stdio MCP servers through the
    environment that owns the selected plugin root.
    3. **Backend skills:** add a hosted skill source whose catalog and
    bodies are accessed through extension tools rather than a filesystem.
    4. **Connectors and hooks:** activate those components through their
    owning extensions, using the same selected-root boundary and
    component-specific runtime.
    5. **Durable selection:** define the desired-selection lifecycle,
    persist it, and make resume, fork, and subagent inheritance explicit
    rather than accidental.
    6. **Local convergence:** incrementally route existing local plugin,
    skill, and MCP loading through the same extension model while preserving
    current local behavior.
    
    Each follow-up remains reviewable as an end-to-end capability. The
    platform selects roots, generic thread extension data carries the
    selection, and the owning extension resolves and operates its component.
    
    ## Verification
    
    Coverage added for:
    
    - app-server end-to-end discovery and explicit invocation of a skill
    inside an executor-selected plugin root
    - exclusive invocation when a selected executor skill collides with a
    local skill name
    - executor filesystem authority for discovery, canonicalization, and
    reads
    - thread extension initialization before lifecycle contributors run
    - stable executor catalog context, explicit invocation, context
    rebuilding, hidden skills, and preserved host/remote catalog behavior
    
    Targeted protocol, core-skills, skills-extension, core lifecycle, and
    app-server executor-skill tests were run during development.
  • feat(app-server): expose account token usage [1 of 2] (#25344)
    ## Why
    
    Token activity is useful account-level context, but terminal clients
    need a supported app-server path to fetch it without reaching into
    ChatGPT backend details directly. The API should also live under the
    broader account usage umbrella so future usage surfaces can be added
    without proliferating user-facing concepts.
    
    ## What Changed
    
    - Add `codex-backend-client` support for the ChatGPT profile token-usage
    payload.
    - Add the v2 `account/usage/read` app-server RPC.
    - Map lifetime usage, peak daily usage, streak, longest task duration,
    and daily buckets into app-server protocol types.
    - Gate the request on Codex-backend auth, which supports ChatGPT auth
    tokens and AgentIdentity.
    - Regenerate the app-server JSON and TypeScript schema fixtures.
    
    ## Token Count Source
    
    `account/usage/read` returns the token-usage aggregate supplied by the
    ChatGPT profile backend. App-server maps that backend-owned aggregate
    into protocol fields; it does not recompute cached-token treatment,
    usage multipliers, or raw input/output totals locally.
    
    ## Stack
    
    1. feat(app-server): expose account token usage [1 of 2] (this PR)
    2. [#25345](https://github.com/openai/codex/pull/25345) feat(tui): add
    token activity command [2 of 2]
    
    ## How to Test
    
    1. Start an app-server client from this branch while authenticated with
    ChatGPT or AgentIdentity.
    2. Call `account/usage/read`.
    3. Confirm the response includes `summary` and `dailyUsageBuckets`.
    4. Also verify a session without Codex-backend auth receives the
    existing auth error path.

  • Encrypt multi-agent v2 message payloads (#26210)
    ## Why
    
    Multi-agent v2 currently routes agent instructions through normal tool
    arguments and inter-agent context. That means the parent model can emit
    plaintext task text, Codex can persist it in history/rollouts, and the
    recipient can receive it as ordinary assistant-message JSON.
    
    This changes the v2 path so agent instructions stay encrypted between
    model calls: Responses encrypts the `message` argument returned by the
    model, Codex forwards only that ciphertext, and Responses decrypts it
    internally for the recipient model.
    
    ## What changed
    
    - Mark the v2 `message` parameter as encrypted for `spawn_agent`,
    `send_message`, and `followup_task`.
    - Treat multi-agent v2 tool `message` values as ciphertext
    unconditionally.
    - Store v2 inter-agent task text in
    `InterAgentCommunication.encrypted_content` with empty plaintext
    `content`.
    - Convert encrypted inter-agent communications into the Responses
    `agent_message` input item before sending the child request.
    - Preserve `agent_message` items across history, rollout, compaction,
    telemetry, and app-server schema paths.
    - Leave multi-agent v1 unchanged.
    
    ## Message shape
    
    The model still calls the v2 tools with a `message` argument, but that
    value is now ciphertext:
    
    ```json
    {
      "name": "spawn_agent",
      "arguments": {
        "task_name": "worker",
        "message": "<ciphertext>"
      }
    }
    ```
    
    Codex stores the task as encrypted inter-agent communication:
    
    ```json
    {
      "author": "/root",
      "recipient": "/root/worker",
      "content": "",
      "encrypted_content": "<ciphertext>",
      "trigger_turn": true
    }
    ```
    
    When Codex builds the recipient request, it forwards the ciphertext
    using the new Responses input item:
    
    ```json
    {
      "type": "agent_message",
      "author": "/root",
      "recipient": "/root/worker",
      "content": [
        {
          "type": "encrypted_content",
          "encrypted_content": "<ciphertext>"
        }
      ]
    }
    ```
    
    Responses decrypts that item internally for the recipient model.
    
    ## Context impact
    
    - Parent context no longer carries plaintext v2 agent task instructions
    from these tool arguments.
    - Codex rollout/history stores ciphertext for v2 agent instructions.
    - Recipient requests receive an `agent_message` item instead of
    assistant commentary JSON for encrypted task delivery.
    - Plaintext completion/status notifications are still plaintext because
    they are Codex-generated status messages, not encrypted model tool
    arguments.

  • [codex] Support model-defined reasoning efforts (#26444)
    ## Summary
    - accept non-empty model-defined reasoning effort values while
    preserving built-in effort behavior
    - propagate the non-Copy effort type through core, app-server, TUI,
    telemetry, and persistence call sites
    - preserve string wire encoding and expose an open-string schema for
    clients
    - update model selection and shortcut behavior for model-advertised
    effort values
    
    ## Root cause
    `ReasoningEffort` gained a string-backed custom variant, so it could no
    longer implement `Copy` or rely on derived closed-enum serialization.
    Existing consumers still moved effort values from shared references and
    assumed a fixed built-in value set.
    
    ## Validation
    - `just fmt`
    - Local tests and compilation were not run per request; relying on CI.
  • 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.

    ## Summary
    
    Adds an optional `clientId` field to app-server v2 `UserInput` and
    carries it through the core `UserInput` model so clients can correlate
    echoed user input items without relying on payload equality.
    
    ## Details
    
    - Adds `client_id: Option<String>` to core `UserInput` variants.
    - Exposes the v2 app-server field as `clientId` on the wire and in
    generated TypeScript.
    - Preserves the id when converting between app-server v2 and core
    protocol types.
    - Regenerates app-server schema fixtures.

  • feat(app-server): include turns page on thread resume (#23534)
    ## Summary
    
    The client currently calls `thread/resume` to establish live updates and
    immediately follows it with `thread/turns/list` to hydrate recent turns.
    This lets `thread/resume` return that page directly, eliminating a round
    trip and the ordering/deduplication gap between the two calls.
    
    Experimental clients opt in with `initialTurnsPage: { limit,
    sortDirection, itemsView }`. The response returns `initialTurnsPage` as
    a `TurnsPage`, including cursors for paging further back in history.
    Keeping the controls in a nested opt-in object provides the useful
    `thread/turns/list` knobs without spreading page-specific parameters
    across `thread/resume`.

  • Restore legacy image detail values (#24644)
    ## Why
    
    Older persisted rollouts can contain `input_image.detail` values of
    `auto` or `low` from before `ImageDetail` was narrowed to
    `high`/`original`. Current deserialization rejects those values, which
    can make resume skip later compacted checkpoints and reconstruct an
    oversized raw suffix before the next compaction attempt.

    [openai/codex#20693](https://github.com/openai/codex/pull/20693) added
    image-detail plumbing for app-server `UserInput` so input images could
    explicitly request `detail: original`. The Slack discussion behind that
    PR was about ScreenSpot / bridge evals where user input images were
    resized, while tool output images already had MCP/code-mode ways to
    request image detail.
    
    In review, the intended new API surface was narrowed to `high` and
    `original`: default to `high`, allow `original` when callers need
    unchanged image handling, and avoid encouraging new `auto` or `low`
    usage. That policy still makes sense for newly emitted values.
    
    The missing compatibility piece is persisted history. Older rollouts can
    already contain `auto` and `low`, and resume reconstructs typed history
    by deserializing those rollout records. Rejecting old values at that
    boundary causes valid compacted checkpoints to be skipped. This PR
    restores `auto` and `low` as real variants so old records deserialize
    and round-trip without being rewritten as `high`, while product paths
    can continue to default to `high` and avoid emitting `auto` for new
    behavior.
    
    ## What changed
    
    - Restored `ImageDetail::Auto` and `ImageDetail::Low` as first-class
    protocol values.
    - Preserved `auto`/`low` through rollout deserialization, MCP image
    metadata, code-mode image output, and schema/type generation.
    - Kept local image byte handling conservative: only `original` switches
    to original-resolution loading; `auto`/`low`/`high` continue through the
    resize-to-fit path while retaining their detail value.
    - Added regression coverage for enum round-tripping and code-mode `low`
    detail handling.
    
    ## Testing
    
    - `just write-app-server-schema`
    - `just test -p codex-protocol`
    - `just test -p codex-tools`
    - `just test -p codex-code-mode`
    - `just test -p codex-app-server-protocol`
    - `just test -p codex-core
    suite::rmcp_client::stdio_image_responses_preserve_original_detail_metadata`
    - `just test -p codex-core
    suite::code_mode::code_mode_can_use_mcp_image_result_with_image_helper`
    - Loaded broken rollouts on local fixed builds, and started/completed
    new turns.
    
    I also attempted `just test -p codex-core`; the local broad run did not
    finish green: 2559 tests run, 2467 passed, 55 flaky, 91 failed, 1 timed
    out. The failures were broad timeout/deadline failures across unrelated
    areas; targeted changed-path core tests above passed.
  • Add experimental turn additional context (#24154)
    ## Summary
    
    Adds experimental `additionalContext` support to `turn/start` and
    `turn/steer` so clients can provide ephemeral external context, such as
    browser or automation state, without turning that plumbing into a
    visible user prompt or triggering user-prompt lifecycle behavior.
    
    ## API Shape
    
    The parameter shape is:
    
    ```ts
    additionalContext?: Record<string, {
      value: string
      kind: "untrusted" | "application"
    }> | null
    ```
    
    Example:
    
    ```json
    {
      "additionalContext": {
        "browser_info": {
          "value": "Active tab is CI failures.",
          "kind": "untrusted"
        },
        "automation_info": {
          "value": "CI rerun is in progress.",
          "kind": "application"
        }
      }
    }
    ```
    
    The keys are opaque and caller-defined.
    
    ## Context Injection
    
    When provided, accepted entries are inserted into model context as
    hidden contextual message items, not as visible thread user-message
    items.
    
    `kind: "untrusted"` entries are inserted with role `user`:
    
    ```text
    <external_${key}>${value}</external_${key}>
    ```
    
    `kind: "application"` entries are inserted with role `developer`:
    
    ```text
    <${key}>${value}</${key}>
    ```
    
    Values are not escaped. Each value is truncated to 1k approximate tokens
    before wrapping.
    
    For `turn/start`, accepted additional context is inserted before normal
    user input. For `turn/steer`, additional context is merged only when the
    steer includes non-empty user input; context-only steers still reject as
    empty input.
    
    ## Dedupe Strategy
    
    `AdditionalContextStore` lives on session state and stores the latest
    complete additional-context map.
    
    Each `turn/start` or non-empty `turn/steer` treats its
    `additionalContext` as the current complete set of values. Entries are
    injected only when the key is new or the exact entry for that key
    changed, including `value` or `kind`. After merging, the store is
    replaced with the provided map, so omitted keys are removed from the
    retained set and can be injected again later if reintroduced.
    
    Omitting `additionalContext`, passing `null`, or passing an empty object
    resets the store to empty and injects nothing.
    
    ## What Changed
    
    - Threads experimental v2 `additionalContext` through app-server into
    core turn start and steer handling.
    - Adds separate contextual fragment types for untrusted user-role
    context and application developer-role context.
    - Uses pending response input items so additional context can be
    combined with normal user input without treating it as prompt text.
    - Adds integration coverage for start/steer flow, role routing,
    dedupe/reset behavior, deletion/re-add behavior, hook-blocked input
    behavior, empty context-only steer rejection, external-fragment marker
    matching, and truncation.
  • Use thread config for TUI MCP inventory (#24532)
    ## Summary
    `/mcp` in the TUI should reflect the current loaded thread, including
    project-local MCP servers from that thread config. Before this change,
    `mcpServerStatus/list` only read the latest global MCP config, so the
    active chat could miss project-local servers.
    
    This adds optional `threadId` to `mcpServerStatus/list`. When present,
    app-server resolves the loaded thread and lists MCP status from the
    refreshed effective config for that thread; when omitted, existing
    global config behavior stays unchanged.
    
    The TUI now sends the active chat thread id for `/mcp` and `/mcp
    verbose`, carries that origin through the async inventory result, and
    ignores stale completions if the user has switched threads before the
    fetch returns. The app-server schemas were regenerated.
    
    ## Follow-up
    Once this app-server API change lands, the desktop app should make the
    same `threadId` plumbing so its MCP inventory also uses the current
    thread config.
    
    Fixes #23874
  • fix(app-server): fix optional bool annotations (#24099)
    `#[serde(default)]` wasn't sufficient for our generated TS types to
    reflect that clients didn't have to set them. We also need
    `skip_serializing_if = "std::ops::Not::not"`. This is already a rule in
    our agents.md file.
  • Make goals feature on by default and no longer experimental (#23732)
    ## Why
    
    The `goals` feature is ready to be available without requiring users to
    opt into experimental features. Keeping it behind the beta flag leaves
    persisted thread goals and automatic goal continuation disabled by
    default.
    
    This PR also marks the goal-related app server APIs and events as no
    longer experimental.
    
    ## What changed
    
    - Mark `goals` as `Stage::Stable`.
    - Enable `goals` by default in `codex-rs/features/src/lib.rs`.
  • add encryptedcontent to functioncalloutput (#23500)
    add new `EncryptedContent` variant to `FunctionCallOutputContentItem`
    ahead of standalone websearch.
    
    we need to be able to receive and pass encrypted function call output
    from the new web search endpoint back to responsesapi, as we cannot
    expose direct search results.
  • feat: Add vertical remote plugin collection support (#23584)
    - Adds an explicit vertical marketplace kind for plugin/list that
    fail-open fetches collection=vertical only when full remote plugins are
    disabled.
    
    - Renames the global remote marketplace/cache identity to
    openai-curated-remote and materializes remote installs with backend
    release versions and app manifests.
  • 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.
  • Fix empty rollout path app-server handling (#23400)
    ## Summary
    - Coerce `path: ""` to `None` at the v2 protocol params deserialization
    boundary for `thread/resume` and `thread/fork`.
    - Restore the pre-ThreadStore running-thread resume behavior: if
    `threadId` is already running, rejoin it by id and treat a non-empty
    `path` only as a consistency check; otherwise cold resume keeps `history
    > path > threadId` precedence.
    - Add protocol, resume, and fork regression coverage for empty path
    payloads; refresh app-server schema fixtures for the clarified params
    docs.
    
    ## Tests
    - `just fmt`
    - `just write-app-server-schema`
    - `cargo test -p codex-app-server-protocol
    thread_path_params_deserialize_empty_path_as_none`
    - `cargo test -p codex-app-server-protocol --test schema_fixtures`
    - `cargo test -p codex-app-server empty_path`
    - `RUST_MIN_STACK=8388608 cargo test -p codex-app-server --test all
    thread_resume_rejects_mismatched_path_for_running_thread_id`
    - `RUST_MIN_STACK=8388608 cargo test -p codex-app-server --test all
    thread_resume_uses_path_over_non_running_thread_id`
  • app-server: use profile ids in v2 permission params (#23360)
    ## Why
    
    The v2 app-server permission profile fields are experimental, but the
    previous migration kept a legacy object payload for profile selection.
    That made clients aware of server-owned `activePermissionProfile`
    metadata such as `extends`, and it kept a
    `legacy_additional_writable_roots` path even though
    `runtimeWorkspaceRoots` now owns runtime workspace-root selection.
    
    This PR makes the client contract match the intended model: clients
    select a permission profile by id, and the server resolves and reports
    active profile provenance in response payloads.
    
    Follow-up to #22611.
    
    ## What Changed
    
    - Changed `thread/start`, `thread/resume`, `thread/fork`, and
    `turn/start` permission profile selection to plain profile id strings.
    - Changed `command/exec.permissionProfile` to a plain profile id string
    for the same client/server ownership split.
    - Removed `PermissionProfileSelectionParams` and the legacy `{ type:
    "profile", modifications: [...] }` compatibility deserializer.
    - Updated app-server, TUI, and `codex exec` call sites to send only ids,
    while keeping `activePermissionProfile` as server response metadata.
    - Updated app-server docs and schema fixtures for the revised
    `command/exec.permissionProfile` shape.
    
    ## Verification
    
    - `cargo test -p codex-app-server-protocol`
    - `RUST_MIN_STACK=8388608 cargo test -p codex-app-server`
    - `cargo test -p codex-exec`
    - `RUST_MIN_STACK=8388608 cargo test -p codex-tui`

  • feat(app-server): add optional thread_id to experimentalFeature/list (#23335)
    ## Why
    
    `experimentalFeature/list` reports effective feature enablement, but
    currently does not resolve it against a working directory where
    project-local config.toml files can exist and toggle on/off features
    when merged into the effective config after resolving the various config
    layers. That means we effectively (and incorrectly) ignore features set
    in project-local config.
    
    To address that, this PR exposes an optional `thread_id` param which
    allows us to load the thread's `cwd.
    
    ## Testing
    
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server experimental_feature_list`
  • goal: pause continuation loops on usage limits and blockers (#23094)
    Addresses #22833, #22245, #23067
    
    ## Why
    `/goal` can keep synthesizing turns even when the next turn cannot make
    meaningful progress. Hard usage exhaustion can replay failing turns, and
    repeated permission or external-resource blockers can keep burning
    tokens while waiting for user or system intervention.
    
    ## What changed
    - Add resumable `blocked` and `usageLimited` goal states. As with
    `paused`, goal continuation stops with these states.
    - Move to `usageLimited` after usage-limit failures.
    - Allow the built-in `update_goal` tool to set `blocked` only under
    explicit repeated-impasse guidance. Updated goal continuation prompt to
    specify that agent should use `blocked` only when it has made at least
    three attempts to get past an impasse.
    
    Most of the files touched by this PR are because of the small app server
    protocol update.
    
    ## Validation
    
    I manually reproduced a number of situations where an agent can run into
    a true impasse and verified that it properly enters `blocked` state. I
    then resumed and verified that it once again entered `blocked` state
    several turns later if the impasse still exists.
    
    I also manually reproduced the usage-limit condition by creating a
    simulated responses API endpoint that returns 429 errors with the
    appropriate error message. Verified that the goal runtime properly moves
    the goal into `usageLimited` state and TUI UI updates appropriately.
    Verified that `/goal resume` resumes (and immediately goes back into
    `ussageLImited` state if appropriate).
    
    
    ## Follow-up PRs
    
    Small changes will be needed to the GUI clients to properly handle the
    two new states.
  • [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.
  • Preserve image detail in app-server inputs (#20693)
    ## Summary
    
    - Add optional image detail to user image inputs across core, app-server
    v2, thread history/event mapping, and the generated app-server
    schemas/types.
    - Preserve requested detail when serializing Responses image inputs:
    omitted detail stays on the existing `high` default, while explicit
    `original` keeps local images on the original-resolution path.
    - Support `high`/`original` consistently for tool image outputs,
    including MCP `codex/imageDetail`, code-mode image helpers, and
    `view_image`.
  • [codex] Use compaction_trigger item for remote compaction v2 (#22809)
    ## Why
    
    Remote compaction v2 was still using `context_compaction` as both the
    request trigger and the compacted output shape. The Responses API now
    has the landed contract for this flow: Codex sends a dedicated `{
    "type": "compaction_trigger" }` input item, and the backend returns the
    standard `compaction` output item with encrypted content.
    
    This aligns the v2 path with that wire contract while preserving the
    existing local compacted-history post-processing behavior.
    
    ## What changed
    
    - Add `ResponseItem::CompactionTrigger` and regenerate the app-server
    protocol schema fixtures.
    - Send `compaction_trigger` from `remote_compaction_v2` instead of a
    payload-less `context_compaction`.
    - Collect exactly one backend `compaction` output item, then reuse the
    existing compacted-history rebuilding path.
    - Treat the trigger item as a transient request marker rather than model
    output or persisted rollout/memory content.
    
    ## Verification
    
    - `cargo test -p codex-protocol compaction_trigger`
    - `cargo test -p codex-core remote_compact_v2`
    - `cargo test -p codex-core compact_remote_v2`
    - `cargo test -p codex-core
    responses_websocket_sends_response_processed_after_remote_compaction_v2`
    - `just write-app-server-schema`
    - `cargo test -p codex-app-server-protocol schema_fixtures`
  • app-server: use permission ids and runtime workspace roots (#22611)
    ## Why
    
    This PR builds on [#22610](https://github.com/openai/codex/pull/22610)
    and is the app-server side of the migration from mutable per-turn
    `SandboxPolicy` replacement toward selecting immutable permission
    profiles by id plus mutable runtime workspace roots.
    
    Once permission profiles can carry their own immutable
    `workspace_roots`, app-server no longer needs to mutate the selected
    `PermissionProfile` just to represent thread-specific filesystem
    context. The mutable part now lives on the thread as explicit
    `runtimeWorkspaceRoots`, while `:workspace_roots` remains symbolic until
    the sandbox is realized for a turn.
    
    ## What Changed
    
    - Replaced the v2 permission-selection wrapper surface with plain
    profile ids for `thread/start`, `thread/resume`, `thread/fork`, and
    `turn/start`.
    - Removed the API surface for profile modifications
    (`PermissionProfileSelectionParams`,
    `PermissionProfileModificationParams`,
    `ActivePermissionProfileModification`).
    - Added experimental `runtimeWorkspaceRoots` fields to the thread
    lifecycle and turn-start APIs.
    - Threaded runtime workspace roots through core session/thread
    snapshots, turn overrides, app-server request handling, and command
    execution permission resolution.
    - Kept session permission state symbolic so later runtime root updates
    and cwd-only implicit-root retargeting rebind `:workspace_roots`
    correctly.
    - Updated the embedded clients just enough to send and restore the new
    thread state.
    - Refreshed the generated schema/TypeScript artifacts and the app-server
    README to match the new contract.
    
    ## Verification
    
    Targeted coverage for this layer lives in:
    
    - `codex-rs/app-server-protocol/src/protocol/v2/tests.rs`
    - `codex-rs/app-server/tests/suite/v2/thread_start.rs`
    - `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
    - `codex-rs/app-server/tests/suite/v2/turn_start.rs`
    - `codex-rs/core/src/session/tests.rs`
    
    The key regression checks exercise that:
    
    - `runtimeWorkspaceRoots` resolve against the effective cwd on thread
    start.
    - Profile-declared workspace roots are excluded from the runtime
    workspace roots returned by app-server.
    - A turn-level runtime workspace-root update persists onto the thread
    and is returned by `thread/resume`.
    - A named permission profile selected on one turn remains symbolic so a
    later runtime-root-only turn update changes the actual sandbox writes.
    - A cwd-only turn update retargets the implicit runtime cwd root while
    preserving additional runtime roots.
    - The protocol fixtures and generated client artifacts stay in sync with
    the string-based permission selection contract.

  • [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.

    <summary>E2E DeviceCheck validation</summary>
    
    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`).

  • feat: Update plugin share settings with discoverability (#21637)
    Requires discoverability on plugin/share/updateTargets so the server can
    manage workspace link access consistently, including auto-adding the
    workspace principal for UNLISTED.
    
    Also rejects LISTED on share creation and blocks client-supplied
    workspace principals while preserving response parsing for LISTED.
  • 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.
  • 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.
  • 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.
  • 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
    standalone ServiceTier TS enum

  • 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.
  • [codex-analytics] rework thread_source for thread analytics (#20949)
    ## Summary
    - make `thread_source` an explicit optional thread-level field on
    `thread/start`, `thread/fork`, and returned thread payloads
    - persist `thread_source` in rollout/session metadata so resumed live
    threads retain the original value
    - replace the old best-effort `session_source` -> `thread_source`
    mapping with an explicit caller-supplied analytics classification
    
    ## Why
    Before this change, analytics `thread_source` was populated by a
    best-effort mapping from `session_source`. `session_source` describes
    the runtime/client surface, not the actual thread-level origin, so that
    projection was not accurate enough to distinguish cases such as `user`,
    `subagent`, `memory_consolidation`, and future thread origins reliably.
    
    Making `thread_source` explicit keeps one thread-level analytics field
    while letting callers provide the real classification directly instead
    of recovering it indirectly from `session_source`.
    
    ## Impact
    For new analytics events, `thread_source` now reflects the explicit
    thread-level classification supplied by the caller rather than an
    inferred value derived from `session_source`. Existing protocol fields
    remain optional; callers that omit `threadSource` now produce `null`
    instead of a best-effort inferred value.
    
    ## Validation

  • 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
    core/src/windows_sandbox_tests.rs`
    - Added unit tests for the pure readiness mapping in
    `core/src/windows_sandbox_tests.rs`
    - 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] 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.

  • feat: add remote compaction v2 Responses client path (#20773)
    ## Why
    
    This adds the `remote_compaction_v2` client path so remote compaction
    can run through the normal Responses stream and install a
    `context_compaction` item that trigger a compaction.
    
    The goal is to migrate some of the compaction logic on the client side
    
    We keeps the v2 transport behind a feature flag while letting follow-up
    requests reuse the compacted context instead of falling back to the
    legacy compaction item shape.
    
    ## What changed
    
    - add `ResponseItem::ContextCompaction` and refresh the generated
    app-server / schema / TypeScript fixtures that expose response items on
    the wire
    - add `core/src/compact_remote_v2.rs` to send compaction through the
    standard streamed Responses client, require exactly one
    `context_compaction` output item, and install that item into compacted
    history
    - route manual compact and auto-compaction through the v2 path when
    `remote_compaction_v2` is enabled, while keeping the existing remote
    compaction path as the fallback
    - preserve the new item type across history retention, follow-up request
    construction, telemetry, rollout persistence, and rollout-trace
    normalization
    - add targeted coverage for the feature flag, `context_compaction`
    serialization, rollout-trace normalization, and remote-compaction
    follow-up behavior
    
    ## Verification
    
    - added protocol tests for `context_compaction`
    serialization/deserialization in `protocol/src/models.rs`
    - added rollout-trace coverage for `context_compaction` normalization in
    `rollout-trace/src/reducer/conversation_tests.rs`
    - added remote compaction integration coverage for v2 follow-up reuse
    and mixed compaction output streams in
    `core/tests/suite/compact_remote.rs`

  • Add remote plugin skill read API (#20150)
    ## Summary
    
    Adds an app-server `plugin/skill/read` method for remote plugin skill
    markdown. The new method calls the plugin-service skill detail endpoint
    and returns `skill_md_contents`, so clients can preview skills for
    remote plugins before the bundle is installed locally.
    
    ## Why
    
    Uninstalled remote plugin skills do not have local `SKILL.md` files.
    Without an on-demand remote read, the desktop plugin details UI cannot
    render the skill details modal for those skills.
    
    ## Validation

    We need a way to list the available hooks to expose via the TUI and App
    so users can view and manage their hooks
    
    ## What
    
    - Adds `hooks/list` for one or more `cwd` values that returns discovered
    hook metadata
    
    ## Stack

    2. This PR - openai/codex#19778
    3. openai/codex#19840
    4. openai/codex#19882
    
    ## Review Notes
    
    The generated schema files account for most of the raw diff, these files
    have the core change:
    
    - `hooks/src/engine/discovery.rs` builds the inventory entries during
    hook discovery while leaving runtime handlers focused on execution.
    - `app-server/src/codex_message_processor.rs` wires `hooks/list` into
    the app-server flow for each requested `cwd`.
    - `app-server-protocol/src/protocol/v2.rs` defines the new v2
    request/response payloads exposed on the wire.
    
    ### Core Changes
    
    `core/src/plugins/manager.rs` adds `plugins_for_layer_stack(...)` so
    `skills/list` and `hooks/list`can resolve plugin state for each
    requested `cwd`
