  • fix: Recover from sqlite directory being a file (#27719)
    Missed this file in the last PR -- this ensures that if you're in the
    really-weird edge case of your sqlite directory being a file, that it
    will fix it and recover properly.
  • [codex] Remove async_trait from first-party code (#27475)
    ## Why
    
    First-party async traits should expose their `Send` contracts explicitly
    without requiring `async_trait`. This completes the migration pattern
    established in #27303 and #27304.
    
    ## What changed
    
    - Replaced the remaining first-party `async_trait` traits with native
    return-position `impl Future + Send` where statically dispatched and
    explicit boxed `Send` futures where object safety is required.
    - Kept implementations behavior-preserving, outlining existing async
    bodies into inherent methods where that keeps the diff reviewable.
    - Removed all direct first-party `async-trait` dependencies and the
    workspace dependency declaration.
    - Added a cargo-deny policy that permits `async-trait` only through the
    remaining transitive wrapper crates.
    - Updated `rand` from 0.8.5 to 0.8.6 to resolve RUSTSEC-2026-0097 and
    keep the full cargo-deny check passing.
    
    ## Validation
    
    - `just test -p codex-exec-server`: 216 passed, 2 skipped.
    - `just test -p codex-model-provider`: 39 passed.
    - `just test -p codex-core` and `just test`: changed tests passed;
    remaining failures are environment-sensitive suites unrelated to this
    migration.

  • [codex] Load user instructions through an injected provider (#27101)
    ## Why
    
    We want to remove implicit use of `$CODEX_HOME` from `codex-core` and
    make embedders responsible for supplying user-level instructions. This
    also ensures user instructions load when no primary environment is
    selected.
    
    ## What changed
    
    Stacked on #27415, which makes `codex exec` surface thread-scoped
    runtime warnings.
    
    - Added `UserInstructionsProvider` to `codex-extension-api`, with
    absolute source attribution and recoverable loading warnings.
    - Added `codex-home` with the filesystem-backed provider for
    `AGENTS.override.md` and `AGENTS.md`, preserving precedence, fallback,
    trimming, lossy UTF-8 handling, and the existing uncapped global
    instruction size.
    - Removed global instruction loading from `Config` and require
    `ThreadManager` callers to inject a provider.
    - Load provider instructions once for each fresh root runtime, including
    runtimes without a primary environment. Running sessions retain their
    snapshot, while child agents inherit the parent snapshot without
    invoking the provider.
    - Keep provider instructions separate while loading project `AGENTS.md`,
    then assemble the model-visible instructions with the existing ordering,
    source attribution, warning, and turn-context behavior.
    - Wired the Codex home provider through the CLI, app server, MCP server,
    core facade, and thread-manager sample.
    
    ## Validation
    
    - `just test -p codex-home -p codex-extension-api`
    - `just test -p codex-core agents_md`
    - `just test -p codex-core guardian`
    - `just test -p codex-app-server

  • [codex] migrate ExecutorFileSystem paths to PathUri (#27424)
    ## Why
    
    We're moving exec-server to use PathUri for its internal path
    representations.
    
    ## What
    
    Move `ExecutorFileSystem` APIs to use `PathUri` instead of
    `AbsolutePathBuf`. Future changes will convert higher-level parts of
    exec-server.
  • feat: disable orchestrator skills for now (#27646)
    Temp disable orchestrator-only skills while waiting for the endpoint to
    be fixed
  • [codex] Propagate plugin app categories (#27420)
    ## What
    - Parse optional `.app.json` `category` overrides for plugin apps.
    - Add nullable `category` to `AppSummary` and `AppTemplateSummary` in
    the app-server protocol.
    - Fall back from `branding.category` to the first non-empty
    `app_metadata.categories` value when building app/template summaries.
    - Regenerate schema/type fixtures and update plugin read/install tests.
    
    ## Why
    The plugin details UI needs a normalized per-app category. Some apps
    only provide their default category in metadata, while others need a
    local `.app.json` override.
  • skills: decouple the skills extension from core (#27413)
    ## Why
    
    `ext/skills` currently depends on `codex-core` for two host concerns:
    reading the concrete `Config` type and borrowing core-owned
    model-context fragment types. That coupling prevents the extension from
    being assembled independently above core and leaves context that belongs
    to the skills feature owned by core.
    
    This stacked PR introduces the host boundary needed for the broader
    extension migration while intentionally preserving existing skills
    behavior. It is stacked on #27404.
    
    ## What changed
    
    - Adds a small public `SkillsExtensionConfig` view and makes skills
    installation generic over the host config type.
    - Requires the host to map its config into that view; app-server
    supplies the current `Config` values.
    - Moves the available-skills and selected-skill context fragment
    implementations into `ext/skills`, preserving their roles, markers, and
    rendered bytes.
    - Removes the direct `codex-core` dependency from
    `codex-skills-extension`.
    - Keeps local discovery, invocation, side effects, and the
    `codex-core-skills` compatibility types unchanged for later staged PRs.
    
    ## Behavior
    
    This adds no capability and is intended to have no user-visible or
    model-visible behavior change. The install API and ownership boundary
    change internally; emitted skills context remains byte-for-byte
    compatible.
    
    ## Validation
    
    - Updates the skills extension integration coverage to use a host-owned
    test config.
    - Asserts the complete rendered catalog and selected-skill fragments,
    including their roles and markers.
    - `just bazel-lock-check`
    - Rust tests and Clippy were not run locally per request; CI will run
    them.
  • skills: make backend plugin skills invocable without an executor (#27387)
    ## Why
    
    #27198 made the extension-owned `codex_apps` MCP connection the hosted
    plugin runtime, but its `mcp/skill` resources still bypassed the skills
    extension. App-server could list and read those resources through
    generic MCP APIs, but a thread with no selected environment did not
    expose them in the model's skills catalog or load their `SKILL.md`
    through `$skill`.
    
    Hosted skills should stay remote while using the same typed catalog,
    source authority, deduplication, bounded contextual catalog, and
    selected-skill prompt injection as host and executor skills. They should
    not be downloaded or exposed as ambient filesystem paths.
    
    ## What changed
    
    - Add a session-scoped `McpResourceClient` over the replaceable MCP
    connection manager so resource list/read calls follow startup and
    refresh replacements.
    - Add a `BackendSkillProvider` that pages `codex_apps` resources,
    accepts bounded and validated `mcp/skill` entries, and reads a selected
    skill's `SKILL.md` through the same MCP connection.
    - Register the remote provider in app-server and include it in the
    skills catalog even when a thread has no selected capability roots or
    executor.
    - Contribute hosted skill metadata through the bounded
    `AvailableSkillsInstructions` developer-context path, exclude remote
    entries from per-turn catalog injection, and classify `<skills>`
    messages as contextual developer content so rollback can trim and
    rebuild them correctly.
    
    ## Testing
    
    - Extend the app-server MCP resource integration test with
    `environments: []` to exercise two-page discovery, filter a
    non-`mcp/skill` resource, verify the escaped developer catalog entry and
    user-role `<skill>` fragment containing the fetched `SKILL.md`, and
    preserve generic MCP resource reads.
    - Add core event-mapping coverage that classifies `<skills>` developer
    messages as contextual history.
  • [codex] Pass auth mode to plugin manager (#27517)
    ## Summary
    - Add auth mode state to `PluginsManager`.
    - Sync the plugin manager auth mode when `ThreadManager` is created and
    when account auth changes.
    - Route plugin load outcomes through an auth-aware projection hook so
    follow-up plugin filtering can stay inside `core-plugins`.
    
    ## Motivation
    This prepares plugin capability loading to be configured by auth mode,
    such as hiding or exposing app/MCP-backed plugin surfaces based on
    whether the user is using ChatGPT auth or API-key auth, without leaking
    those details outside the plugin manager.
    
    ## Tests
    - `just fmt`
    - `just test -p codex-core-plugins`
    - `env -u CODEX_SANDBOX_NETWORK_DISABLED -u CODEX_SANDBOX just test -p
    codex-core thread_manager::tests`
    - `env -u CODEX_SANDBOX_NETWORK_DISABLED -u CODEX_SANDBOX just test -p

  • [codex] Remove redundant plugin app auth state (#27465)
    ## Summary
    
    - remove the redundant `needsAuth` field from `AppSummary` and generated
    app-server schemas
    - stop `plugin/read` from querying Apps MCP solely to hydrate unused
    connector auth state
    - preserve `plugin/install.appsNeedingAuth` membership and
    `app/list.isAccessible` as the authentication signals
    
    ## Why
    
    Codex App and TUI do not consume `plugin/read.plugin.apps[].needsAuth`.
    Hydrating it could establish an Apps MCP connection and discover tools
    on a cold `plugin/read` request, adding avoidable latency. The plugin
    APIs are still marked under development, so removing this wire field is
    preferable to retaining a misleading default.
    
    ## Verification
    
    - `just write-app-server-schema`
    - `just fmt`
    - `just test -p codex-app-server-protocol`

  • [codex] Skip local curated discovery for remote plugins (#27311)
    ## Summary
    
    - skip the local `openai-curated` marketplace before marketplace loading
    when tool-suggest discovery uses remote plugins
    - preserve existing marketplace listing behavior for all other callers
    and when remote plugins are disabled
    - add regression coverage proving the curated marketplace is excluded
    before its malformed manifest can be read
    
    ## Why
    
    Tool-suggest discovery previously loaded every local `openai-curated`
    plugin manifest and only discarded that marketplace afterward when
    remote plugins were enabled. The remote catalog is used in that mode, so
    the local scan consumed CPU without contributing discoverable plugins.
    
    ## Impact
    
    Remote-plugin tool suggestion discovery no longer reads the local
    curated marketplace and its plugin manifests. `openai-bundled`,
    configured marketplaces, normal `plugin/list` behavior, and local
    curated discovery when remote plugins are disabled are unchanged.
    
    ## Validation
    
    - `just test -p codex-core-plugins
    list_marketplaces_can_skip_openai_curated_before_loading`
    - `just test -p codex-core

  • [codex] add /import for external agents (#27071)
    ## Why
    
    External-agent import should be discoverable and deliberate without
    blocking startup or claiming the public `codex [PROMPT]` CLI namespace.
    The slash command keeps the flow local to the interactive TUI and reuses
    the existing app-server import API.
    
    ## What changed
    
    - add the user-facing `/import` slash command
    - detect external-agent importable items only when the command is
    invoked
    - run imports through the embedded local app-server
    - show start and completion messages, refresh configuration, and block
    duplicate imports while one is pending
    - reject the flow for unsupported remote and local-daemon sessions
    
    ## Validation
    
    - `just test -p codex-tui external_agent_config_migration` (10 passed)
    - manually exercised an isolated TUI fixture with existing
    external-agent setup and session data using a fresh `CODEX_HOME`
    - verified picker customization, plugin and session detection, import
    completion, repeated invocation, and imported-session resume context
    - the broader `just test -p codex-tui` run passed 2,805 tests, with 2
    unrelated guardian feature-flag failures and 4 skipped tests
    
    ## Draft follow-ups
    
    - review whether completion messaging should remain attached to the
    initiating chat if the user switches chats during an import
    - review shutdown semantics for an in-progress background import

  • [codex] Raise app-server recursion limit (#27421)
    ## Summary
    
    Unblock Rust release builds after tracing instrumentation increased the
    async future query depth beyond rustc's default limit.
    
    Set the `codex-app-server` crate recursion limit to 256. This changes
    compilation only; runtime behavior is unchanged.
    
    ## Validation
    
    - `just test -p codex-app-server`
    - `cargo build --release --bin codex-app-server`
  • fix: Auto-recover from corrupted sqlite databases (#26859)
    Further investigation of the sqlite incidents showed that the problems
    are due to corruption from the older version of SQLite that we recently
    upgraded, and that the data is truly corrupted in the root database --
    recovery of all data is not possible. Given that the data is
    reconstructable from the rollouts on disk, we should just auto-backup
    the database and let codex rebuild the rollout info from the disk
    rollouts.
    
    The new behavior is that appserver auto-backs-up and rebuilds (with logs
    reflecting that behavior). The CLI now pops a message letting you know
    this happened and the paths of the backed-up corrupt db and the new
    database. There is also context added so that the desktop app can read
    the rebuild info from it and inform the user with it.
  • 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 app-server background terminal process APIs (#26041)
    ## Summary
    
    Codex Apps needs app-server as the source of truth for chat-started
    background terminals instead of guessing from local process trees.
    
    This PR adds experimental v2 APIs to list and terminate background
    terminals for a loaded thread using app-server process ids, so clients
    can manage background terminals without local PID discovery.
    
    ## Changes
    
    - `thread/backgroundTerminals/list` returns paginated background
    terminal records with `itemId`, app-server `processId`, `command`,
    `cwd`, nullable `osPid`, nullable `cpuPercent`, and nullable `rssKb`.
    - `thread/backgroundTerminals/terminate` terminates one running
    background terminal by app-server `processId` and returns whether a
    process was terminated.
    - Background terminal list and terminate operations use unified-exec
    process manager state as their source of truth.
  • [codex] Fix post-merge analytics integration failures (#27285)
    ## Why
    
    Recent merges left `main` with analytics integration build failures.
    Local Cargo runs also made the trimmed-skills test depend on
    developer-installed skills, while Bazel used an isolated home.
    
    ## What changed
    
    - Clone `thread_metadata.thread_source` when constructing goal analytics
    event parameters.
    - Group app-server thread extension inputs into
    `ThreadExtensionDependencies`.
    - Isolate the trimmed-skills test home so its exact fixture count is
    stable across Cargo and Bazel.
    
    ## Validation
    
    - `cargo check -p codex-analytics`
    - `just test -p codex-analytics` (71 tests)
    - `just test -p codex-app-server` (837 tests; one unrelated zsh-fork
    timeout passed on retry)
  • [codex-analytics] emit goal lifecycle analytics (#27078)
    ## Why
    - Currently, there is no analytics event for `/goal` behavior
    - Existing events cannot identify goal execution or its resulting
    outcome
    - The original update in
    [#26182](https://github.com/openai/codex/pull/26182) was implemented
    before `/goal` moved into `codex-goal-extension`.
    
    ## What Changed
    - Adds `codex_goal_event` serialization and enrichment to
    `codex-analytics`
    - Emits goal events from the canonical `codex-goal-extension` mutation
    and accounting paths:
      - `created` when a new logical goal is persisted
      - `usage_accounted` when cumulative goal usage is persisted
      - `status_changed` when the stored goal status changes
      - `cleared` when the goal is deleted
    - Preserves causal `turn_id` for turn driven events and uses null
    attribution for external or idle lifecycle events
    - Changes goal deletion to return the deleted row so `cleared` retains
    the stable goal ID
    
    ## Event Details
    
    Includes standard analytics metadata along with goal specific fields:
    - `goal_id`: Stable ID stored in the local SQLite goal row and shared
    across the goal's events
    - `event_kind`: Observed operation (see the 4 lifecycle events cited in
    the above bullet)
    - `goal_status`: Resulting or last stored status: `active`, `paused`,
    `blocked`, `usage_limited`, etc.
      - `has_token_budget`: Indicates whether a token budget is configured
      - `turn_id`: Causal turn ID, or null when no causal turn exists
    - `cumulative_tokens_accounted`: Cumulative tokens on `usage_accounted`
    events; null otherwise
    - `cumulative_time_accounted_seconds`: Cumulative active time on
    `usage_accounted` events; null otherwise

  • 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
  • Route hosted Apps MCP through extensions (#27191)
    ## Stack
    
    - Base: #27184
    - This PR is the second vertical and should be reviewed against
    `jif/external-plugins-1`, not `main`.
    
    ## Why
    
    CCA is moving toward a split runtime where the orchestrator may have no
    filesystem or executor, but it still needs to activate remotely hosted
    plugin components. HTTP MCP servers are the simplest complete example:
    they need configuration and host authentication, but they do not need an
    executor process.
    
    The Apps MCP endpoint is currently synthesized by a special-purpose
    loader inside the MCP runtime. That works locally, but it leaves hosted
    MCP activation outside the extension model being established in #27184.
    It also makes the Apps path a poor foundation for plugins whose skills,
    MCP servers, connectors, and hooks may come from different sources or
    execute in different places.
    
    This PR moves that one behavior behind an extension-owned contribution
    while preserving the existing local fallback. It deliberately does not
    introduce a generic plugin activation framework.
    
    ## What changed
    
    ### MCP extension contribution
    
    `codex-extension-api` gains an ordered `McpServerContributor` contract.
    A contributor returns typed `Set` or `Remove` overlays for MCP server
    configuration; later contributors win for the names they own.
    
    The contract stays at the existing MCP configuration boundary.
    Extensions do not create a second connection manager or transport
    abstraction.
    
    ### Hosted Apps MCP extension
    
    A new `codex-mcp-extension` contributes the reserved `codex_apps` server
    from the existing Apps feature, ChatGPT base URL, path override, and
    product SKU configuration.
    
    When `apps_mcp_path_override` is enabled for `https://chatgpt.com`, the
    resulting streamable HTTP endpoint is
    `https://chatgpt.com/backend-api/ps/mcp`. The existing ChatGPT-auth gate
    remains authoritative, so this server can run in an orchestrator-only
    process without being exposed for API-key sessions.
    
    ### One resolved runtime view
    
    `McpManager` now distinguishes three views:
    
    - **configured:** config- and plugin-backed servers before extension
    overlays;
    - **runtime:** configured servers plus host-installed extension
    contributions;
    - **effective:** runtime servers after auth gating and compatibility
    built-ins.
    
    App-server installs the hosted MCP extension and uses the runtime view
    for thread startup, refresh, status, threadless resource reads,
    connector discovery, and MCP OAuth lookup. This keeps
    `mcpServer/oauth/login` consistent with the servers exposed by the other
    MCP APIs. The hosted Apps server itself continues to use existing
    ChatGPT host authentication rather than MCP OAuth.
    
    ## Compatibility
    
    Hosts that do not install the MCP extension retain the existing Apps MCP
    synthesis path. This preserves current local-only, CLI, and
    standalone-host behavior while app-server exercises the extension path.
    
    Disabling Apps removes the reserved `codex_apps` entry, and losing
    ChatGPT auth removes it from the effective runtime view. Executor
    availability is not consulted for this HTTP transport.
    
    ## Follow-ups
    
    The next vertical will resolve a manifest-declared stdio MCP server from
    an executor-selected plugin root and execute it in the environment that
    owns that root. Later verticals can add backend-owned skills, connector
    metadata, hooks, durable selection semantics, and incremental local
    convergence without changing the component-specific runtime boundaries
    introduced here.
    
    ## Verification
    
    Focused coverage was added for:
    
    - contributing the hosted Apps MCP at `/backend-api/ps/mcp` without an
    executor;
    - requiring ChatGPT auth in the effective runtime view;
    - removing a reserved configured Apps server when the Apps feature is
    disabled.
    
    `cargo check -p codex-app-server -p codex-mcp-extension -p
    codex-extension-api -p codex-mcp` passed. Tests and Clippy were not run
    locally under the current development instruction; CI provides the full
    validation pass.
  • [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.
  • app-server: reject direct input to multi-agent v2 sub-agents (#27173)
    ## Why
    
    Multi-agent v2 sub-agents are owned and coordinated by their parent
    agent. Allowing an app-server client to start or steer turns on a
    spawned child bypasses the multi-agent messaging path and creates a
    second, conflicting source of work for that sub-agent.
    
    ## What changed
    
    - Reject direct `turn/start` and `turn/steer` requests targeting
    multi-agent v2 thread-spawn sub-agents.
    - Identify these targets using both the thread's resolved multi-agent
    version and its `SubAgentSource::ThreadSpawn` session source, leaving
    root threads, v1 agents, and other sub-agent types unchanged.
    - Return a consistent invalid-request error before validating or
    applying the submitted input.
    
    ## Testing
    
    - Added an app-server integration test that spawns a real multi-agent v2
    child and verifies that direct `turn/start` and `turn/steer` requests
    are rejected.
  • Avoid rereading rollout history during cold resume (#27031)
    ## Summary
    
    - reuse the history-bearing `StoredThread` loaded while probing for a
    running thread
    - avoid rereading and reparsing the rollout when that probe finds no
    active process
    - reload after shutting down a loaded thread because shutdown may flush
    newer rollout items
    - add a regression test that verifies cold resume performs one
    history-bearing store read
    
    ## Problem
    
    `thread/resume` first reads the persisted thread with history while
    checking whether the thread is
    already running. When no running process exists, cold resume currently
    falls through to
    `resume_thread_from_rollout`, which reads and parses the same history
    again.
    
    That duplicate work grows with rollout size and remains on the
    synchronous resume path even when
    the caller requests `excludeTurns`.
    
    ## Background
    
    The duplicate read was introduced by #24528, which fixed resume
    overrides for idle cached
    threads. To support resumes specified by rollout path,
    `resume_running_thread` began loading the
    stored thread with history so it could resolve the canonical thread ID
    and determine whether a
    cached `CodexThread` was already loaded.
    
    That history is needed when the loaded-thread path handles the request.
    On a cold miss, however,
    the function's boolean result could only report that no loaded thread
    handled the request. It
    discarded the history-bearing `StoredThread`, and the normal cold-resume
    path immediately loaded
    and parsed the same rollout again.
    
    This change preserves the idle cached-thread behavior from #24528 while
    allowing the cold-resume
    path to reuse the probe result.
    
    ## Performance
    
    I benchmarked real retained rollouts using isolated `CODEX_HOME`
    directories, explicit rollout
    paths, debug builds of the commit and its exact parent, and alternating
    parent/patch order. The
    table below uses `thread/resume` with `excludeTurns: true`; response
    payload sizes were identical.
    
    | Rollout size | Records | Parent median | Patch median | Median paired
    saving |
    | ---: | ---: | ---: | ---: | ---: |
    | 6 MB | 3,574 | 541 ms | 441 ms | 132 ms |
    | 30 MB | 15,220 | 1.505 s | 1.041 s | 701 ms |
    | 60 MB | 31,453 | 2.644 s | 1.742 s | 970 ms |
    | 149 MB | 100,874 | 10.506 s | 7.156 s | 3.350 s |
    | 559 MB | 259,734 | 27.759 s | 16.725 s | 9.836 s |
    
    The absolute saving increases with thread size, as expected when
    removing one complete JSONL
    history read and parse. Total resume time is also content-dependent, so
    the relationship is not
    perfectly linear.
    
    I also tested full-history resume with `excludeTurns: false`. The
    response payload was
    byte-identical between variants, and the same size-dependent improvement
    remained visible:
    
    | Rollout size | Parent median | Patch median | Median paired saving |
    | ---: | ---: | ---: | ---: |
    | 6 MB | 1.052 s | 904 ms | 270 ms |
    | 30 MB | 2.667 s | 1.762 s | 924 ms |
    | 60 MB | 8.464 s | 6.272 s | 3.680 s |
    | 149 MB | 26.719 s | 12.118 s | 14.601 s |

  • app-server: clear stale thread watches after v2 agent interruption (#27166)
    ## Why
    
    PR #27007 moved MultiAgentV2 interruption reporting from the legacy
    collaboration close event to `SubAgentActivity::Interrupted`.
    App-server's missing-thread cleanup still ran only for the legacy event,
    so an interrupted child that had already been unloaded could remain
    marked as loaded and running in `ThreadWatchManager`. That leaves thread
    status and running-turn accounting stale, including the count used
    during graceful shutdown.
    
    ## What changed
    
    - Handle `SubAgentActivity::Interrupted` separately in app-server event
    processing.
    - Remove the child's thread watch when `ThreadManager` no longer has
    that thread.
    - Continue forwarding the same completed sub-agent activity notification
    to clients.
    
    ## Testing
    
    - Added a regression test that starts with a running watch for an
    unloaded child, applies the interrupted activity event, and verifies the
    watch is removed, the running count returns to zero, and the client
    notification is still emitted.
  • multi-agent: add path-based v2 activity tracking (#27007)
    ## Why
    
    Multi-agent v2 identifies agents by canonical paths, but its tool
    handlers still emitted the larger legacy collaboration begin/end events
    built around nickname and role metadata. App-server, rollout-trace,
    analytics, and TUI consumers therefore lacked one compact path-based
    completion signal that behaved consistently across live events and
    replay.
    
    The TUI also needs a bounded `/agent` status surface for v2 agents. It
    should use recent local activity for previews, refresh liveness without
    loading full histories, and keep the legacy picker available when no
    path-backed v2 agent is known.
    
    ## What changed
    
    - Replace the v2 `spawn_agent`, `send_message`, `followup_task`, and
    `interrupt_agent` legacy lifecycle emissions with a success-only
    `SubAgentActivity` event. The event records the tool call ID, occurrence
    time, affected thread, canonical agent path, and `started`,
    `interacted`, or `interrupted` kind.
    - Expose the activity as a completion-only app-server v2
    `subAgentActivity` thread item in live notifications and reconstructed
    history, regenerate the protocol schemas, and count it in sub-agent tool
    analytics.
    - Track canonical paths from live activity and loaded-thread metadata in
    the TUI, and render the activity in live and replayed transcripts.
    - Make `/agent` list running path-backed agents with summaries from
    bounded local event buffers. Each summary is capped at 240 graphemes,
    the scan is capped at six recent items, only the last three wrapped
    lines are shown, and command output is omitted. Liveness falls back to
    metadata-only `thread/read` when local turn state is unavailable.
    - Persist the activity as a terminal rollout-trace runtime payload and
    reduce it to the corresponding spawn, send, follow-up, or close
    interaction edge. `interrupt_agent` is classified as a close-edge
    operation.
    - Preserve the legacy picker when no path-backed v2 agent is known.
    
    ## Compatibility
    
    App-server v2 clients that consumed `collabAgentToolCall` begin/end
    pairs for these tools must handle the new completion-only
    `subAgentActivity` item. Legacy v1 collaboration behavior is unchanged.

  • Use cached remote plugin catalog for plugin list (#26932)
    ## Summary
    
    This changes the default remote plugin marketplace listing to use the
    cached global remote catalog when it is already present on disk. The
    foreground `plugin/list` response can then return from the local catalog
    cache instead of waiting on `/ps/plugins/list`.
    
    When a cached global catalog was present at the start of the request,
    `plugin/list` still schedules a background refresh through the existing
    plugin-list background task path so the disk cache is updated for future
    requests. Cache misses keep the existing synchronous remote fetch path
    and write the cache, and they do not schedule an extra duplicate
    background `/ps/plugins/list` refresh.
    
    Installed/enabled state continues to come from the existing remote
    installed overlay path. This change only affects the global remote
    catalog directory data used by `plugin/list`.

  • Pair thread environment settings (#26687)
    ## Why
    
    Thread cwd and environment selections are a single logical setting in
    core: updating one without the other can silently desynchronize the
    next-turn execution context. This change makes that relationship
    explicit in the internal thread settings flow while preserving the
    existing app-server public API shape.
    
    ## What changed
    
    - Moved the cwd/environment pair through internal
    `ThreadSettingsOverrides.environment_settings` instead of a top-level
    internal `cwd` field.
    - Kept `thread/settings/update` public params unchanged, with app-server
    translating top-level `cwd` into the paired internal settings shape.
    - Moved `Op::UserInput` environment overrides into thread settings so
    user turns and settings updates use the same core path.
    - Updated core, app-server, MCP, memories, sample, and test callsites to
    construct the paired settings shape.

  • [codex] Speed up external agent session imports (#26637)
    ## Why
    
    Importing large external-agent session histories currently starts a full
    live Codex thread for every imported session. This initializes unrelated
    runtime systems and repeats expensive transcript, metadata, hashing, and
    ledger work.
    
    On a 50-session, 238 MiB fixture, the existing path took roughly 70
    seconds to complete the import and 77 seconds end to end.
    
    ## What changed
    
    - Persist imported sessions directly through `ThreadStore` instead of
    starting full live threads.
    - Process imports through a bounded five-session pipeline.
    - Parse, extract, and hash each source file in one pass.
    - Move blocking source preparation onto the blocking thread pool.
    - Reuse prepared content hashes and update the import ledger once per
    batch.
    - Avoid metadata readback for newly written rollouts.
    - Preserve imported conversation history and visible thread metadata.
    - Keep the implementation out of `codex-core` and avoid changes to the
    public `ThreadStore` trait.
    
    ## Performance
    
    For the same 50-session, 238 MiB fixture:
    
    | Path | Import completion | End to end |
    | --- | ---: | ---: |
    | Existing import | 69.61s | 76.62s |
    | This change | 5.95s | 6.58s |
    
    All 50 sessions imported successfully with no warnings or contention
    signals.
    
    ## Validation

    - Verified imports do not initialize unrelated required MCP servers.
    - Verified previously imported source versions are skipped and changed
    sources can be imported again.
    - Verified imported rollouts remain readable through thread listing and

  • fix(app-server): avoid blocking connection cleanup (#26852)
    ## Why
    
    Remote-control app-server sessions can reconnect every 5-7 seconds when
    the shared transport-event queue fills. The queue's consumer handled
    `ConnectionClosed` by awaiting all in-flight RPCs for the disconnected
    connection. A stuck RPC therefore blocked processing of replacement
    connection and initialize events until remote-control forwarding hit its
    five-second timeout and reconnected again.
    
    Related issue: N/A (internal remote-control incident investigation).
    
    ## What Changed
    
    - Split fast RPC admission closure from draining:
    `ConnectionRpcGate::close()` rejects queued and future RPCs, while
    `shutdown()` continues waiting for RPCs that already started.
    - Close a disconnected connection's RPC gate before spawning the
    existing RPC drain and resource cleanup in a tracked background task, so
    the transport-event consumer remains available without waiting for
    active RPCs.
    - Reap completed cleanup tasks during normal operation, drain them
    during graceful shutdown, and abort them during forced shutdown.
    - Add regression coverage for closing with an active RPC, rejecting
    post-close requests without polling them, and preserving the existing
    shutdown wait behavior.
    
    ## Verification
    
    `just test -p codex-app-server --lib connection_rpc_gate` passes all 6
    tests, including the new close-versus-drain regression coverage.
  • fix(tui): scope MCP startup status by thread (#26639)
    ## Why
    
    MCP startup failures from spawned subagents were rendered as global
    notifications, so a child thread's failure could pollute the visible
    parent transcript. Routing the notification to the child exposed two
    related replay problems: session refresh could discard the buffered
    event, and a newly created child `ChatWidget` did not know the expected
    MCP server set, which could leave its startup spinner running after
    every server had settled.
    
    MCP startup diagnostics should remain visible in the thread that owns
    the startup without affecting other transcripts. The protocol also needs
    to support a future app-scoped MCP lifecycle where startup is not owned
    by any thread.
    
    ## Reported Behavior
    
    The [originating Slack
    report](https://openai.slack.com/archives/C08JZTV654K/p1780604538859939)
    called out that using subagents could turn MCP startup failures into a
    wall of yellow CLI warnings because repeated failures were not
    deduplicated. The intended behavior is for those diagnostics to remain
    visible once in the thread that owns the startup, without polluting the
    parent transcript.
    
    ## What Changed
    
    - add nullable `threadId` ownership to `mcpServer/startupStatus/updated`
    - populate it from the app-server conversation ID for the current
    thread-scoped lifecycle and regenerate the protocol schema and
    TypeScript artifacts
    - treat a missing or null `threadId` as app-scoped without injecting it
    into the active chat transcript
    - route and buffer thread-owned MCP startup notifications by thread in
    the TUI
    - preserve buffered MCP startup events across child session refresh
    - seed expected MCP servers before replaying a thread snapshot so
    startup reaches its terminal state
    - suppress an identical repeated failure warning for the same server
    within one startup round
    
    The owning thread still renders the detailed failure and final `MCP
    startup incomplete (...)` summary.
    
    ## How to Test
    
    1. Configure an optional MCP server named `smoke` that exits during
    initialization.
    2. Launch the TUI with multi-agent support enabled.
    3. Confirm the main thread's own startup failure renders one detailed
    `smoke` warning and one incomplete-startup summary.
    4. Spawn exactly one subagent.
    5. Confirm the parent transcript does not receive the subagent's MCP
    startup failure.
    6. Switch to the subagent thread and confirm it contains exactly one
    detailed `smoke` failure and one incomplete-startup summary.
    7. Confirm the subagent's MCP startup spinner disappears and the thread
    remains usable.
    8. Switch between the parent and subagent and confirm the warnings
    neither move nor duplicate.
    
    Targeted tests:
    
    - `just test -p codex-app-server-protocol`
    - `just test -p codex-app-server
    thread_start_emits_mcp_server_status_updated_notifications`
    - `just test -p codex-tui mcp_startup`
    
    The parent/child behavior and spinner completion were also exercised
    manually in tmux. `just argument-comment-lint` was attempted but blocked
    by an unrelated local Bazel LLVM empty-glob failure; touched Rust
    callsites were inspected manually.
  • permissions: enforce managed permission profile allowlists (#24852)
    ## Why
    
    Permission profile allowlists are an enterprise security boundary, but
    they also need to compose across the managed requirements layers added
    in #24620.
    
    A map representation lets each requirements layer add, allow, or revoke
    individual profiles without replacing an entire array.
    
    ## Managed Contract
    
    Administrators configure the mergeable allow map with
    `allowed_permission_profiles`. A recommended enterprise configuration
    explicitly lists every built-in and custom profile users should be able
    to select:
    
    ```toml
    default_permissions = "review_only"
    
    [allowed_permission_profiles]
    ":read-only" = true
    ":workspace" = true
    review_only = true
    # ":danger-full-access" is intentionally omitted, so it is denied.
    
    [permissions.review_only]
    extends = ":read-only"
    ```
    
    - Profiles whose effective merged value is `true` are allowed.
    - Missing profiles and profiles set to `false` are denied.
    - This is a closed allowlist: built-in profiles and profiles introduced
    in future versions are denied unless explicitly allowed.
    - Explicitly list each built-in profile the enterprise wants to make
    available. Omit built-ins such as `:danger-full-access` when they should
    remain unavailable.
    - Set `default_permissions` explicitly to the allowed profile users
    should receive when they have no local selection.
    - Higher-precedence layers override only the profile keys they define.
    - `false` is only needed when a higher-precedence layer must revoke a
    `true` inherited from a lower layer.
    - Explicit keys must refer to known built-in or managed profiles.
    
    A custom or narrowed allowlist requires an allowed
    `default_permissions`. For compatibility, if both `:workspace` and
    `:read-only` are explicitly allowed, an omitted default resolves to
    `:workspace`; customer configurations should still set the intended
    default explicitly.
    
    When `allowed_permission_profiles` is absent, existing implicit
    permission and legacy `sandbox_mode` behavior is unchanged.
    
    ## What Changed
    
    - Add `allowed_permission_profiles` as a `BTreeMap<String, bool>` that
    merges per profile across requirements layers.
    - Enforce managed defaults, strict denial of omitted profiles, and the
    explicitly allowed standard-pair fallback.
    - Expose `allowedPermissionProfiles` through `configRequirements/read`
    and regenerate its schemas.
    - Add regression coverage for map composition and revocation, managed
    defaults, strict denial of omitted built-ins, and API output.
    
    ## Verification
    
    - Focused `codex-config` coverage for layered map composition and
    revocation
    - Focused `codex-core` coverage for managed defaults, invalid defaults,
    strict denial of omitted built-ins, and the standard built-in pair
    - Focused `codex-app-server` coverage for requirements API output
    - Scoped Clippy for `codex-config`, `codex-core`,
    `codex-app-server-protocol`, and `codex-app-server`
    
    ## Documentation
    
    The managed `requirements.toml` documentation should introduce
    `allowed_permission_profiles` as a closed permission-profile allowlist
    before this setting is published on developers.openai.com.

  • [codex-rs] support v2 personal access tokens (#25731)
    ## Summary
    
    - add v2 personal access token support for `codex login
    --with-access-token` and `CODEX_ACCESS_TOKEN`
    - classify opaque `at-` tokens separately from legacy Agent Identity
    JWTs
    - hydrate required ChatGPT account metadata through AuthAPI
    `/v1/user-auth-credential/whoami`
    - use PATs directly as bearer tokens while preserving existing ChatGPT
    account surfaces
    - expose PAT-backed auth as the explicit `personalAccessToken`
    app-server auth mode
    
    ## Implementation
    
    PAT auth is intentionally small and stateless. Loading a PAT performs
    one AuthAPI metadata request, stores the hydrated metadata in the
    in-memory auth object, and redacts the secret from debug output. Legacy
    Agent Identity JWT handling remains unchanged. The shared access-token
    classifier lives in a private neutral module because it dispatches
    between both credential types.
    
    PAT hydration fails closed when AuthAPI omits any required metadata,
    including email. Hydrated metadata is intentionally not persisted:
    startup performs a live `whoami` preflight so revoked tokens or changed
    account metadata are not accepted from a stale cache.
    
    ## Workspace restriction scope
    
    This change intentionally does **not** apply
    `forced_chatgpt_workspace_id` to PAT authentication. The setting is a
    client-side config guardrail, not an authorization boundary, and PAT
    does not currently require workspace-ID parity. The PAT login and
    `CODEX_ACCESS_TOKEN` paths therefore validate through AuthAPI without
    threading workspace-restriction state through access-token loading.
    Existing workspace checks for non-PAT auth remain on their established
    paths.
    
    ## App-server compatibility
    
    The public app-server `AuthMode` is shared across v1 and v2, and
    PAT-backed auth reports `personalAccessToken` through both APIs.
    Following human review, this intentionally removes the temporary v1
    compatibility mapping that reported PATs as `chatgpt`; the deprecated v1
    API is kept in parity with v2 rather than maintaining a separate closed
    enum. Clients with exhaustive auth-mode handling in either API version
    must add the new case and should generally treat it as ChatGPT-backed
    unless they need PAT-specific behavior.
    
    The v1 auth-status response still omits the raw PAT when `includeToken`
    is requested because that response cannot carry the account metadata
    needed to reuse the credential safely. Persisted PAT auth also omits the
    new enum value so older Codex builds can deserialize `auth.json` and
    infer PAT auth from the credential field after a rollback.
    
    ## Validation
    
    Latest review-fix validation:
    
    - `CARGO_INCREMENTAL=0 just test -p codex-login` (126 passed)
    - `CARGO_INCREMENTAL=0 just test -p codex-cli` (263 passed)
    - `CARGO_INCREMENTAL=0 just test -p codex-cli

  • [2 of 2] Finish moving goal runtime to extension (#26548)
    ## Stack
    
    1. [#26547](https://github.com/openai/codex/pull/26547) - [1 of 2] Align
    goal extension with core behavior
    2. [#26548](https://github.com/openai/codex/pull/26548) - [2 of 2] Move
    goal runtime to extension
    
    ## Why
    
    This PR completes the switch of the goal behavior to the
    extension-backed runtime and removes the old core goal implementation.
    
    ## What Changed
    
    - Installs the goal extension for app-server `ThreadManager` sessions.
    - Routes app-server thread goal `get`, `set`, and `clear` through
    `GoalService`.
    - Uses thread-idle lifecycle emission after goal resume and snapshot
    ordering so the extension can decide whether to continue the goal.
    - Forwards extension goal updates through a FIFO async app-server
    notification path so backpressure does not drop them or reorder updates.
    - Keeps review turns from enabling goal runtime behavior.
    - Plans extension tools before dynamic tools so built-in goal tool names
    keep their old precedence when goals are enabled.
    - Removes the old core goal runtime, core goal tool handlers, and core
    goal tool specs.
    - Updates tests that were coupled to the core-owned goal runtime while
    leaving the legacy `<goal_context>` compatibility path in core for old
    threads.
    - Removes the stale cargo-shear ignore now that `codex-goal-extension`
    is used by the workspace.
    - Keeps realtime event matching exhaustive after removing the old
    goal-specific realtime text path.
    
    
    ## Validation
    
    - Ran manual `/goal` runs in TUI. Validated time accounting matched
    wall-clock time and goal lifecycle state transitions.
  • Speed up TUI startup by reusing plugin discovery (#26469)
    ## Summary
    
    TUI startup loads related plugin data from `hooks/list`, session MCP
    initialization, and plugin skill warmup. These paths repeated filesystem
    discovery and emitted the same plugin warnings, while `hooks/list` and
    account/model bootstrap ran serially.
    
    This change:
    
    - Reuses one immutable plugin load outcome across startup consumers.
    - Keys the cache only on plugin-relevant configuration.
    - Single-flights concurrent plugin loads and prevents invalidated loads
    from repopulating the cache.
    - Runs hook discovery and account/model bootstrap concurrently.
    - Preserves configuration-migration ordering, hook review behavior, and
    accurate startup telemetry.
    
    In 10 alternating release-build launches in the Ruff repository with the
    existing `~/.codex` configuration, median time to the first editable
    composer decreased from 833ms to 504ms. The branch was faster in 9 of 10
    pairs, with a paired median improvement of 312ms.
  • Make runtime workspace roots absolute in app-server API (#26552)
    Stacked on #26532.
    
    ## Why
    
    #26532 moves cwd normalization to the app-server/core boundary.
    `runtimeWorkspaceRoots` still accepted raw paths in v2 requests and in
    `ConfigOverrides`, which left core responsible for interpreting those
    roots later. This makes runtime workspace roots follow the same
    absolute-path boundary as cwd.
    
    ## What
    
    - Change v2 `runtimeWorkspaceRoots` request fields for `thread/start`,
    `thread/resume`, `thread/fork`, and `turn/start` to `AbsolutePathBuf`.
    - Deduplicate already-absolute runtime roots in app-server handlers and
    pass them through `ConfigOverrides.workspace_roots` as
    `AbsolutePathBuf`.
    - Update TUI and exec client request builders to pass absolute runtime
    roots directly.
    - Update app-server docs, schema fixtures, and focused tests for
    absolute runtime roots.
    
    ## Testing
    
    - `just test -p codex-app-server-protocol`
    - `just test -p codex-app-server runtime_workspace_roots`
    - `just test -p codex-core
    session_permission_profile_rebinds_runtime_workspace_roots`
    - `just test -p codex-tui app_server_session`
    - `just test -p codex-exec`
  • feat(app-server): add remote control pairing status RPC (#26450)
    ## What
    
    Exposes the pairing status transport as experimental app-server v2 RPC
    `remoteControl/pairing/status`.
    
    - Adds request/response protocol types for exactly one lookup key:
    `pairingCode` or `manualPairingCode`, returning `{ claimed }`.
    - Registers the RPC with `global_shared_read("remote-control-pairing")`.
    - Wires the method through `MessageProcessor` and
    `RemoteControlRequestProcessor`.
    - Validates missing/conflicting pairing-code params as invalid requests.
    - Documents the RPC in `app-server/README.md`.
    - Adds processor, protocol export, and JSON-RPC integration coverage for
    both code paths.
    
    ## Why
    
    This is the app-server surface the desktop app can poll while the
    QR/manual pairing modal is active.
    
    Depends on https://github.com/openai/codex/pull/26449
    Related backend change: https://github.com/openai/openai/pull/990244
    
    ## Verification
    
    - `cargo test --manifest-path app-server-protocol/Cargo.toml
    remote_control`
    - `cargo test --manifest-path app-server/Cargo.toml remote_control`
    - `cargo fmt --all --check`
    - `git diff --check`
  • Require absolute cwd in thread settings (#26532)
    ## Why
    
    Thread settings cwd overrides are expected to be resolved before they
    enter core. Keeping this boundary as a plain `PathBuf` made it easy for
    core/session code to keep fallback normalization and relative-path
    resolution logic in places that should only receive an already-resolved
    cwd.
    
    This is intentionally the absolute-cwd-only slice: it does not change
    environment selection stickiness or cwd-to-default-environment fallback
    behavior.
    
    ## What changed
    
    - Changes `ThreadSettingsOverrides.cwd`,
    `CodexThreadSettingsOverrides.cwd`, and `SessionSettingsUpdate.cwd` to
    use `AbsolutePathBuf`.
    - Removes core-side cwd normalization/resolution from session settings
    updates.
    - Updates affected core/app-server test helpers and callsites to pass
    existing absolute cwd values or use `abs()` helpers.
    
    ## Validation
    
    Opening as draft so CI can start while local validation continues.
  • 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.
    
    Targeted tests:
    - `just test -p codex-backend-client -p codex-app-server-protocol -p
    codex-app-server`
    - `just write-app-server-schema`
  • [codex] Forward turn moderation metadata through app-server (#25710)
    ## Why
    First-party backends can supply turn-scoped moderation metadata that
    app-server clients need for client-side presentation. Exposing this as
    an experimental typed notification lets opted-in clients consume it
    without interpreting raw Responses API events.
    
    ## What changed
    - forward `response.metadata.openai_chatgpt_moderation_metadata` from
    Responses API SSE and WebSocket streams as turn-scoped moderation
    metadata
    - emit the experimental app-server v2 `turn/moderationMetadata`
    notification with `{ threadId, turnId, metadata }`
    - add app-server integration coverage for the typed moderation metadata
    notification
    
    ## Testing
    - `just test -p codex-core
    build_ws_client_metadata_includes_window_lineage_and_turn_metadata`
    - `just test -p codex-core` (fails locally: 46 failures and 1 timeout,
    primarily missing `test_stdio_server` and shell snapshot timeouts)
    - `just test -p codex-app-server-protocol`
    - `just test -p codex-app-server
    turn_moderation_metadata_emits_typed_notification_v2`
    - `just test -p codex-app-server` (fails locally: 792 passed, 10 failed,
    and 5 timed out; failures are in existing environment-sensitive tests,
    primarily because nested macOS `sandbox-exec` is not permitted)
    - `just write-app-server-schema --experimental --schema-root
    /tmp/codex-app-server-schema-experimental`
  • feat(remote-control): allow pairing while disabled (#26215)
    ## Why
    
    `remoteControl/pairing/start` creates authorization for future
    remote-control connections, so it should not require the live websocket
    to already be enabled. Requiring enable first made pairing depend on
    presence instead of the persisted server enrollment that pairing
    actually uses.
    
    Pairing also needs to recover when that persisted server row is stale.
    If `/server/pair` returns `404`, making the first pairing attempt fail
    forces a manual retry even though the client can clear the stale row and
    create a replacement enrollment immediately.
    
    ## What Changed
    
    - Allow `remoteControl/pairing/start` to reuse or create the persisted
    remote-control server enrollment while remote control is disabled.
    - Keep the selected in-memory enrollment across disable and share it
    with websocket connect so a later enable uses the same selected server.
    - Thread the app-server client name through pairing so stdio persistence
    keeps using the websocket-owned enrollment key.
    - Recover pairing server-token auth failures through the existing
    refresh/auth-recovery path.
    - Recover stale pairing enrollment on `/server/pair` `404` by clearing
    the stale selected enrollment, re-enrolling once, and retrying pairing
    once.
    - Add focused disabled-pairing and stale-pairing recovery coverage.
    
    ## Verification
    
    -
    `remote_control_pairing_start_returns_pairing_artifacts_while_disabled`
    exercises pairing before enable.
    - `remote_control_handle_reenrolls_after_stale_pairing_enrollment`
    exercises stale `/server/pair` `404` recovery without a manual retry.

  • [codex] Expose unavailable app templates in plugin detail (#26317)
    ## Summary
    - Adds `unavailable_app_templates` to the app-server protocol and
    generated schemas/types.
    - Parses plugin-service `release.unavailable_app_templates` in the
    remote plugin client.
    - Maps remote unavailable templates into app-server `PluginDetail`.
    - Defaults local plugins to an empty unavailable app template list.
    
    ## Validation
    - `just write-app-server-schema`
    - `cargo +1.95.0 fmt --manifest-path codex-rs/Cargo.toml --all --check`
    - `cargo +1.95.0 test --manifest-path codex-rs/Cargo.toml -p

    - `git diff --check`
    
    Note: default `cargo check` uses rustc 1.89 locally and failed because
    dependencies require newer Rust, so validation was rerun with installed

  • fix(app-server): expose remote MCP servers in plugin read (#26453)
    ## Why
    
    Remote plugin detail responses include MCP server metadata under
    `release.mcp_servers`, but Codex did not deserialize or propagate that
    field. As a result, `plugin/read` always returned an empty `mcpServers`
    list for remote plugins, so the plugin details pane omitted the MCP
    Servers section even when the remote plugin declares one.
    
    This affects uninstalled plugins as well: the remote detail API is the
    source of truth and returns MCP server keys without requiring a local
    plugin bundle.
    
    ## What changed
    
    - Deserialize MCP server entries from remote plugin detail responses.
    - Normalize their keys into a sorted, deduplicated list on
    `RemotePluginDetail`.
    - Return those keys from app-server `plugin/read` instead of hardcoding
    an empty list.
    - Add regression coverage proving an uninstalled remote plugin returns
    its MCP server names.
    
    ## Test plan
    
    - `just test -p codex-core-plugins`
    - `just test -p codex-app-server plugin_read`
  • [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.
  • Cleanup experimentalFeature/enablement/set (#26312)
    ## Why
    
    `experimentalFeature/enablement/set` still allowed several keys that no
    longer need to be managed through this API. Keeping those keys also
    preserved corresponding special-case logic, including refreshing the
    apps list when the `apps` key was enabled.
    
    The endpoint also rejected an entire request when any key was invalid or
    unsupported. That makes clients brittle when they send a mix of current
    and stale keys, even when the valid entries can still be applied safely.
    
    ## What changed
    
    - remove the feature keys that no longer need to be supported by
    `experimentalFeature/enablement/set`
    - remove the corresponding apps-list refresh path and its auth/config
    plumbing
    - ignore and warn on invalid or unsupported keys while still applying
    valid keys from the same request
    - update the app-server documentation and integration coverage for the
    reduced key set and partial-acceptance behavior
    
    ## Test plan
    
    - `just test -p codex-app-server experimental_feature_enablement_set` (6
    passed)
    - `just test -p codex-app-server` exercised the changed tests
    successfully; unrelated sandbox-dependent and watcher/timing tests
    failed locally
  • Route AGENTS.md loading through environment filesystems (#26205)
    ## Why
    
    Workspace-specific `AGENTS.md` loading needs to use the selected
    environment filesystem so remote workspaces and child agents read
    instructions from their actual environment instead of the host
    filesystem. The app-server should report the same instruction sources
    the initialized thread actually loaded, rather than independently
    rescanning configuration and filesystem state.
    
    ## What changed
    
    - Introduce `LoadedAgentsMd` to retain ordered user, project, and
    internal instructions with their provenance.
    - Load and canonicalize workspace `AGENTS.md` paths through the primary
    `EnvironmentManager` environment, then render the loaded instructions
    when constructing turn context.
    - Expose cached loaded instruction sources from initialized threads and
    use them for app-server start, resume, and fork responses.
    - Preserve global `CODEX_HOME` loading and separator behavior while
    excluding empty project files that did not supply model-visible
    instructions.
    - Add integration coverage for CLI injection, selected-environment
    provenance and rendering, empty environment selection, and cached
    sources on loaded-thread resume.
    
    ## Validation
    
    - `just test -p codex-core agents_md`
    - `just test -p codex-core
    selected_environment_sources_match_model_visible_instructions`
