  • [codex] Add local thread store listing (#17824)
    Builds on top of #17659 
    
    Move the filesystem + sqlite thread listing-related operations inside of
    a local ThreadStore implementation and call ThreadStore from the places
    that used to perform these filesystem/sqlite operations.
    
    This is the first of a series of PRs that will implement the rest of the
    local ThreadStore.
    
    Testing:
    - added unit tests for the thread store implementation
    - adjusted some unit tests in the realtime + personality packages whose
    callsites changed. Specifically I'm trying to hide ThreadMetadata inside
    of the local implementation and make ThreadMetadata a sqlite
    implementation detail concern rather than a public interface, preferring
    the more generate StoredThread interface instead
    - added a corner case test for the personality migration package that
    wasn't covered by the existing test suite
    - adjust the behavior of searched thread listing to run the existing
    local rollout repair/backfill pass _before_ querying SQLite results, so
    callers using ThreadStore::list_threads do not miss matches after a
    partial metadata warm-up
  • Register agent identities behind use_agent_identity (#17386)
    ## Summary
    
    Stack PR 2 of 4 for feature-gated agent identity support.
    
    This PR adds agent identity registration behind
    `features.use_agent_identity`. It keeps the app-server protocol
    unchanged and starts registration after ChatGPT auth exists rather than
    requiring a client restart.
    
    ## Stack
    
    - PR1: https://github.com/openai/codex/pull/17385 - add
    `features.use_agent_identity`
    - PR2: https://github.com/openai/codex/pull/17386 - this PR
    - PR3: https://github.com/openai/codex/pull/17387 - register agent tasks
    when enabled
    - PR4: https://github.com/openai/codex/pull/17388 - use `AgentAssertion`
    downstream when enabled
    
    ## Validation
    
    Covered as part of the local stack validation pass:
    
    - `just fmt`
    - `cargo test -p codex-core --lib agent_identity`
    - `cargo test -p codex-core --lib agent_assertion`
    - `cargo test -p codex-core --lib websocket_agent_task`
    - `cargo test -p codex-api api_bridge`
    - `cargo build -p codex-cli --bin codex`
    
    ## Notes
    
    The full local app-server E2E path is still being debugged after PR
    creation. The current branch stack is directionally ready for review
    while that follow-up continues.
  • register all mcp tools with namespace (#17404)
    stacked on #17402.
    
    MCP tools returned by `tool_search` (deferred tools) get registered in
    our `ToolRegistry` with a different format than directly available
    tools. this leads to two different ways of accessing MCP tools from our
    tool catalog, only one of which works for each. fix this by registering
    all MCP tools with the namespace format, since this info is already
    available.
    
    also, direct MCP tools are registered to responsesapi without a
    namespace, while deferred MCP tools have a namespace. this means we can
    receive MCP `FunctionCall`s in both formats from namespaces. fix this by
    always registering MCP tools with namespace, regardless of deferral
    status.
    
    make code mode track `ToolName` provenance of tools so it can map the
    literal JS function name string to the correct `ToolName` for
    invocation, rather than supporting both in core.
    
    this lets us unify to a single canonical `ToolName` representation for
    each MCP tool and force everywhere to use that one, without supporting
    fallbacks.
  • Make skill loading filesystem-aware (#17720)
    Migrates skill loading to support reading repo skills from the remote
    environment.
  • Spread AbsolutePathBuf (#17792)
    Mechanical change to promote absolute paths through code.
  • fix: Revert danger-full-access denylist-only mode (#17732)
    ## Summary
    
    - Reverts openai/codex#16946 and removes the danger-full-access
    denylist-only network mode.
    - Removes the corresponding config requirements, app-server
    protocol/schema, config API, TUI debug output, and network proxy
    behavior.
    - Drops stale tests that depended on the reverted mode while preserving
    newer managed allowlist-only coverage.
    
    ## Verification
    
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-config network_requirements`
    - `cargo test -p codex-core network_proxy_spec`
    - `cargo test -p codex-core
    managed_network_proxy_decider_survives_full_access_start`
    - `cargo test -p codex-app-server map_requirements_toml_to_api`
    - `cargo test -p codex-tui debug_config_output`
    - `cargo test -p codex-app-server-protocol`
    - `just fix -p codex-config -p codex-core -p codex-app-server-protocol
    -p codex-app-server -p codex-tui`
    - `git diff --cached --check`
    
    Not run: full workspace `cargo test` (repo instructions ask for
    confirmation before that broader run).
  • Refactor plugin loading to async (#17747)
    Simplifies skills migration.
  • Add supports_parallel_tool_calls flag to included mcps (#17667)
    ## Why
    
    For more advanced MCP usage, we want the model to be able to emit
    parallel MCP tool calls and have Codex execute eligible ones
    concurrently, instead of forcing all MCP calls through the serial block.
    
    The main design choice was where to thread the config. I made this
    server-level because parallel safety depends on the MCP server
    implementation. Codex reads the flag from `mcp_servers`, threads the
    opted-in server names into `ToolRouter`, and checks the parsed
    `ToolPayload::Mcp { server, .. }` at execution time. That avoids relying
    on model-visible tool names, which can be incomplete in
    deferred/search-tool paths or ambiguous for similarly named
    servers/tools.
    
    ## What was added
    
    Added `supports_parallel_tool_calls` for MCP servers.
    
    Before:
    
    ```toml
    [mcp_servers.docs]
    command = "docs-server"
    ```
    
    After:
    
    ```toml
    [mcp_servers.docs]
    command = "docs-server"
    supports_parallel_tool_calls = true
    ```
    
    MCP calls remain serial by default. Only tools from opted-in servers are
    eligible to run in parallel. Docs also now warn to enable this only when
    the server’s tools are safe to run concurrently, especially around
    shared state or read/write races.
    
    ## Testing
    
    Tested with a local stdio MCP server exposing real delay tools. The
    model/Responses side was mocked only to deterministically emit two MCP
    calls in the same turn.
    
    Each test called `query_with_delay` and `query_with_delay_2` with `{
    "seconds": 25 }`.
    
    | Build/config | Observed | Wall time |
    | --- | --- | --- |
    | main with flag enabled | serial | `58.79s` |
    | PR with flag enabled | parallel | `31.73s` |
    | PR without flag | serial | `56.70s` |
    
    PR with flag enabled showed both tools start before either completed;
    main and PR-without-flag completed the first delay before starting the
    second.
    
    Also added an integration test.
    
    Additional checks:
    
    - `cargo test -p codex-tools` passed
    - `cargo test -p codex-core
    mcp_parallel_support_uses_exact_payload_server` passed
    - `git diff --check` passed

  • fix(guardian, app-server): introduce guardian review ids (#17298)
    ## Description
    
    This PR introduces `review_id` as the stable identifier for guardian
    reviews and exposes it in app-server `item/autoApprovalReview/started`
    and `item/autoApprovalReview/completed` events.
    
    Internally, guardian rejection state is now keyed by `review_id` instead
    of the reviewed tool item ID. `target_item_id` is still included when a
    review maps to a concrete thread item, but it is no longer overloaded as
    the review lifecycle identifier.
    
    ## Motivation
    
    We'd like to give users the ability to preempt a guardian review while
    it's running (approve or decline).
    
    However, we can't implement the API that allows the user to override a
    running guardian review because we didn't have a unique `review_id` per
    guardian review. Using `target_item_id` is not correct since:
    - with execve reviews, there can be multiple execve calls (and therefore
    guardian reviews) per shell command
    - with network policy reviews, there is no target item ID
    
    The PR that actually implements user overrides will use `review_id` as
    the stable identifier.
  • [codex-analytics] add compaction analytics event (#17155)
    - event for compaction analytics
    - introduces thread-connection and thread metadata caches for data
    denormalization, expected to be useful for denormalization onto core
    emitted events in general
    - threads analytics event client into core (mirrors approved
    implementation in #16640)
    - denormalizes key thread metadata: thread_source, subagent_source,
    parent_thread_id, as well as app-server client and runtime metadata)
    - compaction strategy defaults to memento, forward compatible with
    expected prefill_compaction strategy

  • feat: make rollout recorder reliable against errors (#17214)
    The rollout writer now keeps an owned/monitored task handle, returns
    real Result acks for flush/persist/shutdown, retries failed flushes by
    reopening the rollout file, and keeps buffered items until they are
    successfully written. Session flushes are now real durability barriers
    for fork/rollback/read-after-write paths, while turn completion surfaces
    a warning if the rollout still cannot be saved after recovery.
  • Option to Notify Workspace Owner When Usage Limit is Reached (#16969)
    ## Summary
    - Replace the manual `/notify-owner` flow with an inline confirmation
    prompt when a usage-based workspace member hits a credits-depleted
    limit.
    - Fetch the current workspace role from the live ChatGPT
    `accounts/check/v4-2023-04-27` endpoint so owner/member behavior matches
    the desktop and web clients.
    - Keep owner, member, and spend-cap messaging distinct so we only offer
    the owner nudge when the workspace is actually out of credits.
    
    ## What Changed
    - `backend-client`
    - Added a typed fetch for the current account role from
    `accounts/check`.
      - Mapped backend role values into a Rust workspace-role enum.
    - `app-server` and protocol
      - Added `workspaceRole` to `account/read` and `account/updated`.
    - Derived `isWorkspaceOwner` from the live role, with a fallback to the
    cached token claim when the role fetch is unavailable.
    - `tui`
      - Removed the explicit `/notify-owner` slash command.
    - When a member is blocked because the workspace is out of credits, the
    error now prompts:
    - `Your workspace is out of credits. Request more from your workspace
    owner? [y/N]`
      - Choosing `y` sends the existing owner-notification request.
    - Choosing `n`, pressing `Esc`, or accepting the default selection
    dismisses the prompt without sending anything.
    - Selection popups now honor explicit item shortcuts, which is how the
    `y` / `n` interaction is wired.
    
    ## Reviewer Notes
    - The main behavior change is scoped to usage-based workspace members
    whose workspace credits are depleted.
    - Spend-cap reached should not show the owner-notification prompt.
    - Owners and admins should continue to see `/usage` guidance instead of
    the member prompt.
    - The live role fetch is best-effort; if it fails, we fall back to the
    existing token-derived ownership signal.
    
    ## Testing
    - Manual verification
      - Workspace owner does not see the member prompt.
    - Workspace member with depleted credits sees the confirmation prompt
    and can send the nudge with `y`.
    - Workspace member with spend cap reached does not see the
    owner-notification prompt.

  • [mcp] Expand tool search to custom MCPs. (#16944)
    - [x] Expand tool search to custom MCPs.
    - [x] Rename several variables/fields to be more generic.
    
    Updated tool & server name lifecycles:
    
    **Raw Identity**
    
    ToolInfo.server_name is raw MCP server name.
    ToolInfo.tool.name is raw MCP tool name.
    MCP calls route back to raw via parse_tool_name() returning
    (tool.server_name, tool.tool.name).
    mcpServerStatus/list now groups by raw server and keys tools by
    Tool.name: mod.rs:599
    App-server just forwards that grouped raw snapshot:
    codex_message_processor.rs:5245
    
    **Callable Names**
    
    On list-tools, we create provisional callable_namespace / callable_name:
    mcp_connection_manager.rs:1556
    For non-app MCP, provisional callable name starts as raw tool name.
    For codex-apps, provisional callable name is sanitized and strips
    connector name/id prefix; namespace includes connector name.
    Then qualify_tools() sanitizes callable namespace + name to ASCII alnum
    / _ only: mcp_tool_names.rs:128
    Note: this is stricter than Responses API. Hyphen is currently replaced
    with _ for code-mode compatibility.
    
    **Collision Handling**
    
    We do initially collapse example-server and example_server to the same
    base.
    Then qualify_tools() detects distinct raw namespace identities behind
    the same sanitized namespace and appends a hash to the callable
    namespace: mcp_tool_names.rs:137
    Same idea for tool-name collisions: hash suffix goes on callable tool
    name.
    Final list_all_tools() map key is callable_namespace + callable_name:
    mcp_connection_manager.rs:769
    
    **Direct Model Tools**
    
    Direct MCP tool declarations use the full qualified sanitized key as the
    Responses function name.
    The raw rmcp Tool is converted but renamed for model exposure.
    
    **Tool Search / Deferred**
    
    Tool search result namespace = final ToolInfo.callable_namespace:
    tool_search.rs:85
    Tool search result nested name = final ToolInfo.callable_name:
    tool_search.rs:86
    Deferred tool handler is registered as "{namespace}:{name}":
    tool_registry_plan.rs:248
    When a function call comes back, core recombines namespace + name, looks
    up the full qualified key, and gets the raw server/tool for MCP
    execution: codex.rs:4353
    
    **Separate Legacy Snapshot**
    
    collect_mcp_snapshot_from_manager_with_detail() still returns a map
    keyed by qualified callable name.
    mcpServerStatus/list no longer uses that; it uses
    McpServerStatusSnapshot, which is raw-inventory shaped.
  • Forward app-server turn clientMetadata to Responses (#16009)
    ## Summary
    App-server v2 already receives turn-scoped `clientMetadata`, but the
    Rust app-server was dropping it before the outbound Responses request.
    This change keeps the fix lightweight by threading that metadata through
    the existing turn-metadata path rather than inventing a new transport.
    
    ## What we're trying to do and why
    We want turn-scoped metadata from the app-server protocol layer,
    especially fields like Hermes/GAAS run IDs, to survive all the way to
    the actual Responses API request so it is visible in downstream
    websocket request logging and analytics.
    
    The specific bug was:
    - app-server protocol uses camelCase `clientMetadata`
    - Responses transport already has an existing turn metadata carrier:
    `x-codex-turn-metadata`
    - websocket transport already rewrites that header into
    `request.request_body.client_metadata["x-codex-turn-metadata"]`
    - but the Rust app-server never parsed or stored `clientMetadata`, so
    nothing from the app-server request was making it into that existing
    path
    
    This PR fixes that without adding a new header or a second metadata
    channel.
    
    ## How we did it
    ### Protocol surface
    - Add optional `clientMetadata` to v2 `TurnStartParams` and
    `TurnSteerParams`
    - Regenerate the JSON schema / TypeScript fixtures
    - Update app-server docs to describe the field and its behavior
    
    ### Runtime plumbing
    - Add a dedicated core op for app-server user input carrying turn-scoped
    metadata: `Op::UserInputWithClientMetadata`
    - Wire `turn/start` and `turn/steer` through that op / signature path
    instead of dropping the metadata at the message-processor boundary
    - Store the metadata in `TurnMetadataState`
    
    ### Transport behavior
    - Reuse the existing serialized `x-codex-turn-metadata` payload
    - Merge the new app-server `clientMetadata` into that JSON additively
    - Do **not** replace built-in reserved fields already present in the
    turn metadata payload
    - Keep websocket behavior unchanged at the outer shape level: it still
    sends only `client_metadata["x-codex-turn-metadata"]`, but that JSON
    string now contains the merged fields
    - Keep HTTP fallback behavior unchanged except that the existing
    `x-codex-turn-metadata` header now includes the merged fields too
    
    ### Request shape before / after
    Before, a websocket `response.create` looked like:
    ```json
    {
      "type": "response.create",
      "client_metadata": {
        "x-codex-turn-metadata": "{\"session_id\":\"...\",\"turn_id\":\"...\"}"
      }
    }
    ```
    Even if the app-server caller supplied `clientMetadata`, it was not
    represented there.
    
    After, the same request shape is preserved, but the serialized payload
    now includes the new turn-scoped fields:
    ```json
    {

    ```
    
    ## Validation
    ### Targeted tests added / updated
    - protocol round-trip coverage for `clientMetadata` on `turn/start` and
    `turn/steer`
    - protocol round-trip coverage for `Op::UserInputWithClientMetadata`
    - `TurnMetadataState` merge test proving client metadata is added
    without overwriting reserved built-in fields
    - websocket request-shape test proving outbound `response.create`
    contains merged metadata inside
    `client_metadata["x-codex-turn-metadata"]`
    - app-server integration tests proving:
    - `turn/start` forwards `clientMetadata` into the outbound Responses
    request path
      - websocket warmup + real turn request both behave correctly
      - `turn/steer` updates the follow-up request metadata

    I verified that same failure on a clean detached `HEAD` worktree with an
    isolated `CARGO_TARGET_DIR`, so it is not caused by this patch.
  • Add realtime voice selection (#17176)
    - Add realtime voice selection for realtime/start.
    - Expose the supported v1/v2 voice lists and cover explicit, configured,
    default, and invalid voice paths.
  • Fix stale thread-name resume lookups (#16646)
    Addresses #15943
    
    Problem: Name-based resume could stop on a newer session_index entry
    whose rollout was never persisted, shadowing an older saved thread with
    the same name.
    
    Solution: Materialize rollouts before indexing thread names and make
    name lookup skip unresolved entries until it finds a persisted rollout.
  • Auto-approve MCP server elicitations in Full Access mode (#17164)
    Currently, when a MCP server sends an elicitation to Codex running in
    Full Access (`sandbox_policy: DangerFullAccess` + `approval_policy:
    Never`), the elicitations are auto-cancelled.
    
    This PR updates the automatic handling of MCP elicitations to be
    consistent with other approvals in full-access, where they are
    auto-approved. Because MCP elicitations may actually require user input,
    this mechanism is limited to empty form elicitations.
    
    ## Changeset
    - Add policy helper shared with existing MCP tool call approval
    auto-approve
    - Update `ElicitationRequestManager` to auto-approve elicitations in
    full access when `can_auto_accept_elicitation` is true.
    - Add tests

  • Use AbsolutePathBuf for exec cwd plumbing (#17063)
    ## Summary
    - Carry `AbsolutePathBuf` through tool cwd parsing/resolution instead of
    resolving workdirs to raw `PathBuf`s.
    - Type exec/sandbox request cwd fields as `AbsolutePathBuf` through
    `ExecParams`, `ExecRequest`, `SandboxCommand`, and unified exec runtime
    requests.
    - Keep `PathBuf` conversions at external/event boundaries and update
    existing tests/fixtures for the typed cwd.

  • fix: refresh network proxy settings when sandbox mode changes (#17040)
    ## Summary
    
    Fix network proxy sessions so changing sandbox mode recomputes the
    effective managed network policy and applies it to the already-running
    per-session proxy.
    
    ## Root Cause
    
    `danger_full_access_denylist_only` injects `"*"` only while building the
    proxy spec for Full Access. Sessions built that spec once at startup, so
    a later permission switch to Full Access left the live proxy in its
    original restricted policy. Switching back needed the same recompute
    path to remove the synthetic wildcard again.
    
    ## What Changed
    
    - Preserve the original managed network proxy config/requirements so the
    effective spec can be recomputed for a new sandbox policy.
    - Refresh the current session proxy when sandbox settings change, then
    reapply exec-policy network overlays.
    - Add an in-place proxy state update path while rejecting
    listener/port/SOCKS changes that cannot be hot-reloaded.
    - Keep runtime proxy settings cheap to snapshot and update.
    - Add regression coverage for workspace-write -> Full Access ->
    workspace-write.

    Having to check for errors every time join is called is painful and

  • feat(analytics): generate an installation_id and pass it in responsesapi client_metadata (#16912)
    ## Summary
    
    This adds a stable Codex installation ID and includes it on Responses
    API requests via `x-codex-installation-id` passed in via the
    `client_metadata` field for analytics/debugging.
    
    The main pieces are:
    - persist a UUID in `$CODEX_HOME/installation_id`
    - thread the installation ID into `ModelClient`
    - send it in `client_metadata` on Responses requests so it works
    consistently across HTTP and WebSocket transports

    Preserve explicit null developer-instruction overrides across app-server

  • [codex] reduce module visibility (#16978)
    ## Summary

    APIs instead of reaching through module trees

    - expose environment capabilities (`exec_enabled`, `filesystem_enabled`)
    so tool building can gate behavior explicitly and future
    multi-environment work has a clearer seam
    - suppress env-backed tools when the relevant capability is unavailable,
    including exec tools, `js_repl`, `apply_patch`, `list_dir`, and
    `view_image`
    - keep handler/runtime backstops so disabled environments still reject
    execution if a tool path somehow bypasses registration

  • feat(requirements): support allowed_approval_reviewers (#16701)
    ## Description
    
    Add requirements.toml support for `allowed_approvals_reviewers =
    ["user", "guardian_subagent"]`, so admins can now restrict the use of
    guardian mode.
    
    Note: If a user sets a reviewer that isn’t allowed by requirements.toml,
    config loading falls back to the first allowed reviewer and emits a
    startup warning.
    
    The table below describes the possible admin controls.
    | Admin intent | `requirements.toml` | User `config.toml` | End result |
    |---|---|---|---|
    | Leave Guardian optional | omit `allowed_approvals_reviewers` or set
    `["user", "guardian_subagent"]` | user chooses `approvals_reviewer =
    "user"` or `"guardian_subagent"` | Guardian off for `user`, on for
    `guardian_subagent` + `approval_policy = "on-request"` |
    | Force Guardian off | `allowed_approvals_reviewers = ["user"]` | any
    user value | Effective reviewer is `user`; Guardian off |
    | Force Guardian on | `allowed_approvals_reviewers =
    ["guardian_subagent"]` and usually `allowed_approval_policies =
    ["on-request"]` | any user reviewer value; user should also have
    `approval_policy = "on-request"` unless policy is forced | Effective
    reviewer is `guardian_subagent`; Guardian on when effective approval
    policy is `on-request` |
    | Allow both, but default to manual if user does nothing |
    `allowed_approvals_reviewers = ["user", "guardian_subagent"]` | omit
    `approvals_reviewer` | Effective reviewer is `user`; Guardian off |
    | Allow both, and user explicitly opts into Guardian |
    `allowed_approvals_reviewers = ["user", "guardian_subagent"]` |
    `approvals_reviewer = "guardian_subagent"` and `approval_policy =
    "on-request"` | Guardian on |
    | Invalid admin config | `allowed_approvals_reviewers = []` | anything |
    Config load error |
  • Fix flaky permissions escalation test on Windows (#16825)
    Problem: `rejects_escalated_permissions_when_policy_not_on_request`
    retried a real shell command after asserting the escalation rejection,
    so Windows CI could fail on command startup timing instead of approval
    behavior.
    
    Solution: Keep the rejection assertion, verify no turn permissions were
    granted, and assert through exec-policy evaluation that the same command
    would be allowed without escalation instead of timing a subprocess.

  • [codex] allow disabling environment context injection (#16745)
    This adds an `include_environment_context` config/profile flag that
    defaults on, and guards both initial injection and later environment
    updates to allow skipping injection of `<environment_context>`.
  • remove temporary ownership re-exports (#16626)
    Stacked on #16508.
    
    This removes the temporary `codex-core` / `codex-login` re-export shims
    from the ownership split and rewrites callsites to import directly from
    `codex-model-provider-info`, `codex-models-manager`, `codex-api`,
    `codex-protocol`, `codex-feedback`, and `codex-response-debug-context`.
    
    No behavior change intended; this is the mechanical import cleanup layer
    split out from the ownership move.

  • extract models manager and related ownership from core (#16508)
    ## Summary
    - split `models-manager` out of `core` and add `ModelsManagerConfig`
    plus `Config::to_models_manager_config()` so model metadata paths stop
    depending on `core::Config`
    - move login-owned/auth-owned code out of `core` into `codex-login`,
    move model provider config into `codex-model-provider-info`, move API
    bridge mapping into `codex-api`, move protocol-owned types/impls into
    `codex-protocol`, and move response debug helpers into a dedicated
    `response-debug-context` crate
    - move feedback tag emission into `codex-feedback`, relocate tests to
    the crates that now own the code, and keep broad temporary re-exports so
    this PR avoids a giant import-only rewrite
    
    ## Major moves and decisions
    - created `codex-models-manager` as the owner for model
    cache/catalog/config/model info logic, including the new
    `ModelsManagerConfig` struct
    - created `codex-model-provider-info` as the owner for provider config
    parsing/defaults and kept temporary `codex-login`/`codex-core`
    re-exports for old import paths
    - moved `api_bridge` error mapping + `CoreAuthProvider` into
    `codex-api`, while `codex-login::api_bridge` temporarily re-exports
    those symbols and keeps the `auth_provider_from_auth` wrapper
    - moved `auth_env_telemetry` and `provider_auth` ownership to
    `codex-login`
    - moved `CodexErr` ownership to `codex-protocol::error`, plus
    `StreamOutput`, `bytes_to_string_smart`, and network policy helpers to
    protocol-owned modules
    - created `codex-response-debug-context` for
    `extract_response_debug_context`, `telemetry_transport_error_message`,
    and related response-debug plumbing instead of leaving that behavior in
    `core`
    - moved `FeedbackRequestTags`, `emit_feedback_request_tags`, and
    `emit_feedback_request_tags_with_auth_env` to `codex-feedback`
    - deferred removal of temporary re-exports and the mechanical import
    rewrites to a stacked follow-up PR so this PR stays reviewable
    
    ## Test moves
    - moved auth refresh coverage from `core/tests/suite/auth_refresh.rs` to
    `login/tests/suite/auth_refresh.rs`
    - moved text encoding coverage from
    `core/tests/suite/text_encoding_fix.rs` to
    `protocol/src/exec_output_tests.rs`
    - moved model info override coverage from
    `core/tests/suite/model_info_overrides.rs` to
    `models-manager/src/model_info_overrides_tests.rs`

  • core: cut codex-core compile time 48% with native async SessionTask (#16631)
    ## Why
    
    This continues the compile-time cleanup from #16630. `SessionTask`
    implementations are monomorphized, but `Session` stores the task behind
    a `dyn` boundary so it can drive and abort heterogenous turn tasks
    uniformly. That means we can move the `#[async_trait]` expansion off the
    implementation trait, keep a small boxed adapter only at the storage
    boundary, and preserve the existing task lifecycle semantics while
    reducing the amount of generated async-trait glue in `codex-core`.
    
    One measurement caveat showed up while exploring this: a warm
    incremental benchmark based on `touch core/src/tasks/mod.rs && cargo
    check -p codex-core --lib` was basically flat, but that was the wrong
    benchmark for this change. Using package-clean `codex-core` rebuilds,
    like #16630, shows the real win.
    
    Relevant pre-change code:
    
    - [`SessionTask` with
    `#[async_trait]`](https://github.com/openai/codex/blob/3c7f013f9735e67796c70d95f75f436b7f97e3ec/codex-rs/core/src/tasks/mod.rs#L129-L182)
    - [`RunningTask` storing `Arc<dyn
    SessionTask>`](https://github.com/openai/codex/blob/3c7f013f9735e67796c70d95f75f436b7f97e3ec/codex-rs/core/src/state/turn.rs#L69-L77)
    
    ## What changed
    
    - Switched `SessionTask::{run, abort}` to native RPITIT futures with
    explicit `Send` bounds.
    - Added a private `AnySessionTask` adapter that boxes those futures only
    at the `Arc<dyn ...>` storage boundary.
    - Updated `RunningTask` to store `Arc<dyn AnySessionTask>` and removed
    `#[async_trait]` from the concrete task impls plus test-only
    `SessionTask` impls.
    
    ## Timing
    
    Benchmarked package-clean `codex-core` rebuilds with dependencies left
    warm:
    
    ```shell
    cargo check -p codex-core --lib >/dev/null
    cargo clean -p codex-core >/dev/null
    /usr/bin/time -p cargo +nightly rustc -p codex-core --lib -- \
      -Z time-passes \
      -Z time-passes-format=json >/dev/null
    ```
    
    | revision | rustc `total` | process `real` | `generate_crate_metadata`
    | `MIR_borrow_checking` | `monomorphization_collector_graph_walk` |

    | delta | -47.8% | -47.4% | -67.5% | -69.1% | -68.1% |
    
    For completeness, the warm touched-file benchmark stayed flat (`1.96s`
    parent vs `1.97s` this PR), which is why that benchmark should not be
    used to evaluate this refactor.
    
    ## Verification
    
    - Ran `cargo test -p codex-core`; this change compiled and task-related
    tests passed before hitting the same unrelated 5
    `config::tests::*guardian*` failures already present on the parent
    stack.
  • [codex] Remove codex-core config type shim (#16529)
    ## Why
    
    This finishes the config-type move out of `codex-core` by removing the
    temporary compatibility shim in `codex_core::config::types`. Callers now
    depend on `codex-config` directly, which keeps these config model types
    owned by the config crate instead of re-expanding `codex-core` as a
    transitive API surface.
    
    ## What Changed
    
    - Removed the `codex-rs/core/src/config/types.rs` re-export shim and the
    `core::config::ApprovalsReviewer` re-export.
    - Updated `codex-core`, `codex-cli`, `codex-tui`, `codex-app-server`,
    `codex-mcp-server`, and `codex-linux-sandbox` call sites to import
    `codex_config::types` directly.
    - Added explicit `codex-config` dependencies to downstream crates that
    previously relied on the `codex-core` re-export.
    - Regenerated `codex-rs/core/config.schema.json` after updating the
    config docs path reference.
  • core: remove cross-crate re-exports from lib.rs (#16512)
    ## Why
    
    `codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
    which made downstream crates depend on `codex-core` as a proxy module
    instead of the actual owner crate.
    
    Removing those forwards makes crate boundaries explicit and lets leaf
    crates drop unnecessary `codex-core` dependencies. In this PR, this
    reduces the dependency on `codex-core` to `codex-login` in the following
    files:
    
    ```
    codex-rs/backend-client/Cargo.toml
    codex-rs/mcp-server/tests/common/Cargo.toml
    ```
    
    ## What
    
    - Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
    `codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
    `codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
    `codex-tools`, and `codex-utils-path`.
    - Delete the `default_client` forwarding shim in `codex-rs/core`.
    - Update in-crate and downstream callsites to import directly from the
    owning `codex-*` crate.
    - Add direct Cargo dependencies where callsites now target the owner
    crate, and remove `codex-core` from `codex-rs/backend-client`.
  • Extract MCP into codex-mcp crate (#15919)
    - Split MCP runtime/server code out of `codex-core` into the new
    `codex-mcp` crate. New/moved public structs/types include `McpConfig`,
    `McpConnectionManager`, `ToolInfo`, `ToolPluginProvenance`,
    `CodexAppsToolsCacheKey`, and the `McpManager` API
    (`codex_mcp::mcp::McpManager` plus the `codex_core::mcp::McpManager`
    wrapper/shim). New/moved functions include `with_codex_apps_mcp`,
    `configured_mcp_servers`, `effective_mcp_servers`,
    `collect_mcp_snapshot`, `collect_mcp_snapshot_from_manager`,
    `qualified_mcp_tool_name_prefix`, and the MCP auth/skill-dependency
    helpers. Why: this creates a focused MCP crate boundary and shrinks
    `codex-core` without forcing every consumer to migrate in the same PR.
    
    - Move MCP server config schema and persistence into `codex-config`.
    New/moved structs/enums include `AppToolApproval`,
    `McpServerToolConfig`, `McpServerConfig`, `RawMcpServerConfig`,
    `McpServerTransportConfig`, `McpServerDisabledReason`, and
    `codex_config::ConfigEditsBuilder`. New/moved functions include
    `load_global_mcp_servers` and
    `ConfigEditsBuilder::replace_mcp_servers`/`apply`. Why: MCP TOML
    parsing/editing is config ownership, and this keeps config
    validation/round-tripping (including per-tool approval overrides and
    inline bearer-token rejection) in the config crate instead of
    `codex-core`.
    
    - Rewire `codex-core`, app-server, and plugin call sites onto the new
    crates. Updated `Config::to_mcp_config(&self, plugins_manager)`,
    `codex-rs/core/src/mcp.rs`, `codex-rs/core/src/connectors.rs`,
    `codex-rs/core/src/codex.rs`,
    `CodexMessageProcessor::list_mcp_server_status_task`, and
    `utils/plugins/src/mcp_connector.rs` to build/pass the new MCP
    config/runtime types. Why: plugin-provided MCP servers still merge with
    user-configured servers, and runtime auth (`CodexAuth`) is threaded into
    `with_codex_apps_mcp` / `collect_mcp_snapshot` explicitly so `McpConfig`
    stays config-only.
  • feat: add mailbox concept for wait (#16010)
    Add a mailbox we can use for inter-agent communication
    `wait` is now based on it and don't take target anymore
  • chore: clean up argument-comment lint and roll out all-target CI on macOS (#16054)
    ## Why
    
    `argument-comment-lint` was green in CI even though the repo still had
    many uncommented literal arguments. The main gap was target coverage:
    the repo wrapper did not force Cargo to inspect test-only call sites, so
    examples like the `latest_session_lookup_params(true, ...)` tests in
    `codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.
    
    This change cleans up the existing backlog, makes the default repo lint
    path cover all Cargo targets, and starts rolling that stricter CI
    enforcement out on the platform where it is currently validated.
    
    ## What changed
    
    - mechanically fixed existing `argument-comment-lint` violations across
    the `codex-rs` workspace, including tests, examples, and benches
    - updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
    `tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
    `--all-targets` unless the caller explicitly narrows the target set
    - fixed both wrappers so forwarded cargo arguments after `--` are
    preserved with a single separator
    - documented the new default behavior in
    `tools/argument-comment-lint/README.md`
    - updated `rust-ci` so the macOS lint lane keeps the plain wrapper
    invocation and therefore enforces `--all-targets`, while Linux and
    Windows temporarily pass `-- --lib --bins`
    
    That temporary CI split keeps the stricter all-targets check where it is
    already cleaned up, while leaving room to finish the remaining Linux-
    and Windows-specific target-gated cleanup before enabling
    `--all-targets` on those runners. The Linux and Windows failures on the
    intermediate revision were caused by the wrapper forwarding bug, not by
    additional lint findings in those lanes.
    
    ## Validation
    
    - `bash -n tools/argument-comment-lint/run.sh`
    - `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
    - shell-level wrapper forwarding check for `-- --lib --bins`
    - shell-level wrapper forwarding check for `-- --tests`
    - `just argument-comment-lint`
    - `cargo test` in `tools/argument-comment-lint`
    - `cargo test -p codex-terminal-detection`
    
    ## Follow-up
    
    - Clean up remaining Linux-only target-gated callsites, then switch the
    Linux lint lane back to the plain wrapper invocation.
    - Clean up remaining Windows-only target-gated callsites, then switch
    the Windows lint lane back to the plain wrapper invocation.
  • chore: refactor network permissions to use explicit domain and unix socket rule maps (#15120)
    ## Summary
    
    This PR replaces the legacy network allow/deny list model with explicit
    rule maps for domains and unix sockets across managed requirements,
    permissions profiles, the network proxy config, and the app server
    protocol.
    
    Concretely, it:
    
    - introduces typed domain (`allow` / `deny`) and unix socket permission
    (`allow` / `none`) entries instead of separate `allowed_domains`,
    `denied_domains`, and `allow_unix_sockets` lists
    - updates config loading, managed requirements merging, and exec-policy
    overlays to read and upsert rule entries consistently
    - exposes the new shape through protocol/schema outputs, debug surfaces,
    and app-server config APIs
    - rejects the legacy list-based keys and updates docs/tests to reflect
    the new config format
    
    ## Why
    
    The previous representation split related network policy across multiple
    parallel lists, which made merging and overriding rules harder to reason
    about. Moving to explicit keyed permission maps gives us a single source
    of truth per host/socket entry, makes allow/deny precedence clearer, and
    gives protocol consumers access to the full rule state instead of
    derived projections only.
    
    ## Backward Compatibility
    
    ### Backward compatible
    
    - Managed requirements still accept the legacy
    `experimental_network.allowed_domains`,
    `experimental_network.denied_domains`, and
    `experimental_network.allow_unix_sockets` fields. They are normalized
    into the new canonical `domains` and `unix_sockets` maps internally.
    - App-server v2 still deserializes legacy `allowedDomains`,
    `deniedDomains`, and `allowUnixSockets` payloads, so older clients can
    continue reading managed network requirements.
    - App-server v2 responses still populate `allowedDomains`,
    `deniedDomains`, and `allowUnixSockets` as legacy compatibility views
    derived from the canonical maps.
    - `managed_allowed_domains_only` keeps the same behavior after
    normalization. Legacy managed allowlists still participate in the same
    enforcement path as canonical `domains` entries.
    
    ### Not backward compatible
    
    - Permissions profiles under `[permissions.<profile>.network]` no longer
    accept the legacy list-based keys. Those configs must use the canonical
    `[domains]` and `[unix_sockets]` tables instead of `allowed_domains`,
    `denied_domains`, or `allow_unix_sockets`.
    - Managed `experimental_network` config cannot mix canonical and legacy
    forms in the same block. For example, `domains` cannot be combined with
    `allowed_domains` or `denied_domains`, and `unix_sockets` cannot be
    combined with `allow_unix_sockets`.
    - The canonical format can express explicit `"none"` entries for unix
    sockets, but those entries do not round-trip through the legacy
    compatibility fields because the legacy fields only represent allow/deny
    lists.
    ## Testing
    `/target/debug/codex sandbox macos --log-denials /bin/zsh -c 'curl
    https://www.example.com' ` gives 200 with config
    ```
    [permissions.workspace.network.domains]
    "www.example.com" = "allow"
    ```
    and fails when set to deny: `curl: (56) CONNECT tunnel failed, response
    403`.
    
    Also tested backward compatibility path by verifying that adding the
    following to `/etc/codex/requirements.toml` works:
    ```
    [experimental_network]
    allowed_domains = ["www.example.com"]
    ```
