  • test: run app-server integration tests under Wine (#29788)
    ## Why
    
    Made a mistake when carving #29746 out of my local changes and the test
    was missing from the build graph. Oops!
    
    ## What
    
    Enable the app-server Wine exec test target. Remove the `manual` tag
    from generated Wine-exec test variants so wildcard Bazel test
    invocations select them. Refactor the smoke test to ensure it passes
    with current Windows support.
  • connectors: own app metadata types (#29723)
    ## Why
    
    Connector metadata is consumed by connector discovery, ChatGPT
    integration, core, and TUI code. Treating app-server's wire DTO as the
    shared domain model reverses the intended dependency direction.
    
    ## What changed
    
    - Added connector-owned app branding, review, screenshot, metadata, and
    info types.
    - Added explicit conversions in app-server and TUI while preserving
    app-server's wire payloads.
    - Removed production app-server-protocol dependencies from connectors
    and ChatGPT connector code.
    
    ## Stack
    
    This is PR 4 of 6, stacked on [PR
    #29722](https://github.com/openai/codex/pull/29722). Review only the
    delta from `codex/split-config-layer-types`. Next: [PR
    #29724](https://github.com/openai/codex/pull/29724).
    
    ## Validation
    
    - Connector and tools coverage passed.
    - App-server app-list coverage passed: 13 tests.
  • config: own layer provenance types (#29722)
    ## Why
    
    Config layer provenance describes how effective configuration was
    assembled, so it belongs with the config loader rather than in
    app-server's serialized API types.
    
    ## What changed
    
    - Moved `ConfigLayerSource`, `ConfigLayerMetadata`, and `ConfigLayer`
    ownership into `codex-config`.
    - Kept app-server's wire payloads unchanged and added explicit
    conversions at the app boundary.
    - Removed lower-level app-server-protocol dependencies from config
    consumers.

  • [plugins] Enforce marketplace source admission requirements (#29753)
    ## Why
    
    Managed marketplace source requirements only become effective when every
    local marketplace mutation path applies the same admission decision.
    This change centralizes that decision so CLI, app-server, and
    external-agent migration flows cannot add, install from, or refresh a
    disallowed source.
    
    ## What changed
    
    - Match exact normalized Git repository URLs with an optional exact
    `ref`.
    - Match Git hosts with managed regular expressions.
    - Match local marketplaces by exact absolute path.
    - Preserve the expected path/name boundary for managed OpenAI
    marketplaces.
    - Enforce source admission during marketplace add, plugin install, and
    configured Git marketplace upgrade.
    - Continue upgrading independent marketplaces when one source is
    rejected and return a per-marketplace error.
    - Load the effective requirements stack at CLI, app-server, and
    external-agent migration entry points.
    
    This PR does not filter already configured marketplaces at runtime; that
    remains in draft follow-up #29691.
    
    ## Stack
    
    This is PR 2 of 3 and is based on #29690, which introduces the
    requirements data shape and merge behavior.
    
    ## Test plan
    
    - Source matcher coverage for Git URL/ref, host-pattern, local-path, and
    managed marketplace cases.
    - Marketplace add and plugin install coverage for allowed and rejected
    sources.
    - Marketplace upgrade coverage for rejection and per-marketplace
    continuation.
  • auth: move domain mode below app wire types (#29721)
    ## Why
    
    Authentication mode is a domain concept used by login, model selection,
    telemetry, and transports. Keeping the canonical type in app-server
    protocol forces those lower-level crates to depend on an unrelated wire
    API.
    
    ## What changed
    
    - Added canonical `codex_protocol::auth::AuthMode` domain values.
    - Kept the app-server wire DTO unchanged and added an explicit app-side
    conversion.
    - Removed production app-server-protocol dependencies from login,
    model-provider-info, models-manager, and otel call paths.
    
    ## Stack
    
    This is PR 2 of 6, stacked on [PR
    #29714](https://github.com/openai/codex/pull/29714). Review only the
    delta from `codex/split-json-rpc-protocols`. Next: [PR
    #29722](https://github.com/openai/codex/pull/29722).
    
    ## Validation
    
    - Auth and login coverage passed in the focused protocol/domain test
    run.
    - App-server account and auth conversion coverage passed.
  • [codex] Assign response item IDs in forked history (#29767)
    ## Why
    
    Fork-specific response items, including the subagent usage hint, are
    appended directly to `InitialHistory::Forked`. This bypasses the normal
    history insertion path that assigns missing response item IDs when
    `Feature::ItemIds` is enabled, so the child could reconstruct and
    persist those items without IDs.
    
    ## What changed
    
    - When `Feature::ItemIds` is enabled, assign missing IDs to top-level
    `ResponseItem`s while materializing `InitialHistory::Forked`, before
    both reconstruction and persistence.
    - Preserve existing IDs and use the same owned rollout items for live
    history and persistence.
    - Extract the existing single-item ID allocation logic for reuse by the
    fork path.
    - Add coverage that verifies a fork-only developer message receives the
    same ID in live and persisted history with the feature enabled.
    
    Normal history recording, compacted-history replacement, and fork
    handling all continue to honor `Feature::ItemIds`. External-agent
    imports, normal resume, and nested legacy compaction checkpoints are
    unchanged.
    
    ## Testing
    
    - `just test -p codex-core
    record_initial_history_reconstructs_forked_transcript`
    - `just test -p codex-core
    record_initial_history_assigns_and_persists_id_for_forked_response_item`
  • [codex] Ignore local curated plugins when remote catalog is active (#29765)
    ## Summary
    
    - suppress configured `openai-curated` plugins when the remote plugin
    feature is enabled and auth uses the Codex backend
    - preserve `openai-api-curated` and non-Codex-backend behavior while
    including remote catalog activation in the plugin load cache key
    - add core plugin coverage and an app-server integration test for
    runtime feature enablement
    
    ## Why
    
    The Codex app enables remote plugins through process-local runtime
    feature enablement, which can happen after app-server startup tasks have
    already observed legacy local plugin state. The existing conflict logic
    only preferred a remote plugin when the same plugin was already
    installed remotely, so a configured legacy-only plugin could continue
    exposing skills and other capabilities from `openai-curated`.
    
    ## Impact
    
    When the remote catalog is active, legacy `openai-curated` plugins no
    longer contribute skills, MCP servers, apps, or hooks. Remote installed
    plugins continue to load normally, and `openai-api-curated` remains
    unaffected. This does not change remote fetch, bundle sync, or uninstall
    behavior.

  • [plugins] Add marketplace source requirements (#29690)
    ## Why
    
    Managed deployments need a mergeable way to declare which marketplace
    sources Codex may use. An enterprise-keyed TOML table avoids array merge
    ambiguity and lets every requirements layer use the existing config
    precedence rules without a marketplace-specific merger.
    
    ## Requirements shape
    
    ```toml
    [marketplaces]
    restrict_to_allowed_sources = true
    
    [marketplaces.allowed_sources.company_plugins]
    source = "git"
    url = "https://github.com/example/company-plugins.git"
    ref = "main"
    
    [marketplaces.allowed_sources.internal_git]
    source = "host_pattern"
    host_pattern = "^git\\.example\\.com$"
    
    [marketplaces.allowed_sources.local_plugins]
    source = "local"
    path = "/opt/company/codex-plugins"
    ```
    
    `restrict_to_allowed_sources` follows normal scalar precedence.
    `allowed_sources` follows normal recursive TOML table merge behavior:
    distinct keys accumulate and fields under the same key use normal layer
    precedence. The final `source` value later selects which fields the
    marketplace admission policy interprets.
    
    The raw rule fields remain optional while requirements layers are
    composed, so a higher-priority layer can override only `ref`, `url`, or
    another individual field. Source-specific validation and normalization
    intentionally belong to the marketplace admission layer, not
    requirements merging.
    
    This initial shape includes `git`, `host_pattern`, and `local` sources.
    It does not add npm or path-pattern rules.
    
    ## What changed
    
    - Add the marketplace requirements TOML shape to
    `ConfigRequirementsToml`, `ConfigRequirementsWithSources`, and
    `ConfigRequirements`.
    - Carry marketplace requirements through the existing regular
    requirements merge path.
    - Keep allowed-source entries as raw partial tables for downstream
    policy interpretation.
    - Cover partial same-key overlays, source changes, unknown fields, and
    unmodified local paths.
    
    This PR defines and composes the requirements only. Source admission is
    implemented by the next PR in the stack.
    
    ## Stack
    
    This is PR 1 of 3. #29753 adds source admission on top of this PR; draft
    #29691 will add runtime enforcement after it is rebased later.

  • [codex] Update bundled skill installer guidance (#29768)
    ## Summary
    
    - Update the bundled skill installer's post-install guidance to say the
    skill will be available on the user's next turn.
    - Remove the obsolete instruction to restart Codex.
    
    ## Why
    
    Codex refreshes its skill catalog between turns. The existing bundled
    instruction predates that behavior and causes the model to recommend an
    unnecessary restart.
    
    ## Impact
    
    Released Codex builds will materialize accurate post-install guidance
    for the bundled system skill.
    
    ## Related
    
    - Canonical skill change: https://github.com/openai/skills/pull/507
    
    ## Validation
    
    - `just fmt`
    - `git diff --check`
    - `just test -p codex-app-server
    skills_changed_notification_is_emitted_after_skill_change` (passed
    during investigation)
    
    No test code was added because the existing live-refresh path and
    focused integration test already verify that skill changes are picked up
    without restarting.
  • [codex] Reuse compacted history replacement for new context windows (#29762)
    ## Why
    
    `start_new_context_window` independently replaced in-memory history and
    persisted a compacted checkpoint instead of using the shared
    compacted-history path. That bypassed the centralized missing-item-ID
    assignment when `item_ids` is enabled, so fresh context messages could
    enter the new context window and its persisted replacement history
    without IDs.
    
    This follows up on the token-budget compaction reset flow introduced in
    [#29743](https://github.com/openai/codex/pull/29743).
    
    ## What changed
    
    - Delegate new context-window installation to
    `replace_compacted_history`.
    - Reuse its ID assignment, in-memory replacement, world-state baseline,
    checkpoint persistence, turn-context persistence, and session-start
    bookkeeping.
    - Add focused coverage that verifies generated IDs are present in live
    history and preserved in the persisted replacement history.
    
    ## Testing
    
    - `just test -p codex-core

  • Let image generation extension hosts control output persistence (#29711)
    ## Why
    
    Some extension hosts need generated images returned without writing them
    to the local filesystem or giving the model a local path.
    
    ## What changed
    
    **tl;dr**: we now conduct all extension operations in the image gen
    extension
    
    - Let hosts provide an optional image save root when installing the
    extension.
    - Save images and return path hints only when a save root is configured.
    - Return image data without saving or adding a path hint when no save
    root is configured.
    - Preserve the extension-provided `saved_path` instead of persisting
    extension images again in core.
    - Leave built-in image generation unchanged.
    
    ## Validation
    
    - `just test -p codex-image-generation-extension`

  • test: add app-server auto environment helper (#29746)
    ## Why
    
    Start moving towards app-server tests defaulting to running against
    remote & foreign OS executors. To do so we need a point of indirection
    similar to core integration tests' `build_with_auto_env`, but with the
    flexibility of letting tests control environment registration if they
    need to.
    
    ## What
    
    This adds:
    
    - `TestAppServer::new_with_auto_env()` for constructing an app server
    with a default environment defined by the test runner (e.g. bazel)
    - `TestAppServer::auto_env_params()` for tests to easily acquire turn
    env params tailored to the automatic environment
    - `TestAppServer::send_thread_start_request_with_auto_env()` to make it
    easy for tests to start a thread using the automatic environment
    
    The above methods all fail if the test calling them has set up an
    environment where the automatic environment configuration conflicts with
    test-created state.
    
    ## Validation
    
    Adds a couple of basic smoke tests to the app-server test suite.
    Follow-ups will migrate more tests to use it.
  • chore: assign amsg_ IDs to agent messages (#29750)
    ## Why
    
    The `ItemIds` path fills in missing IDs before response items are
    persisted and emitted as raw item events. `ResponseItem::AgentMessage`
    is part of that same response-item stream, but it was skipped by the
    missing-ID repair path, leaving agent messages without stable item IDs
    while messages and tool items received generated IDs.
    
    Agent messages recorded through `InterAgentCommunication` also need the
    generated ID to survive rollout persistence and resume. Otherwise
    clients can observe an `amsg_` ID for the live raw response item, then
    see that same persisted agent message lose its item ID after restart.
    
    ## What changed
    
    - Assign missing `ResponseItem::AgentMessage` IDs with the `amsg_`
    prefix.
    - Persist the generated item ID on `InterAgentCommunication` and replay
    it back into the reconstructed `ResponseItem::AgentMessage` on resume.
    - Keep the persisted ID out of the model-visible inter-agent message
    envelope.
    - Keep `CompactionTrigger` and `Other` skipped because they do not get
    generated item IDs.
    - Update session/protocol tests for agent-message ID assignment and
    resume preservation.
    
    ## Manual Testing
    
    Run the local dev build using `just c --enable item_ids` to ensure this
    code is exercised:
    
    
    https://github.com/openai/codex/blob/322e33512b2d38d38d705e2ef692a8aca50decac/codex-rs/core/src/session/mod.rs#L2713-L2715
    
    In the `.jsonl` file, I saw entries like:
    
    ```json
    {
      "timestamp": "2026-06-24T00:44:03.098Z",
      "type": "inter_agent_communication",

  • [codex] trace MCP startup latency (#28630)
    ## Summary
    
    - add trace-level instrumentation around per-server MCP setup, client
    construction, initialization, and initial tool listing
    - trace Codex Apps tool and server-info cache loads
    - attach `server_name` to server-scoped spans so slow startup work can
    be attributed to a specific MCP server
    
    ## Why
    
    `session_init.mcp_manager_init` can occasionally be slow, but its
    existing coarse span does not identify whether time is spent loading the
    Codex Apps cache, constructing a client, initializing a transport, or
    listing tools. These definition-level spans provide that breakdown
    without changing startup behavior.
    
    ## Validation
    
    - `just test -p codex-mcp` (87 passed)
    - `just test -p codex-rmcp-client` (86 passed, 2 skipped)
  • core: add wait_for_environment for starting environments (#29745)
    ## Why
    
    With `DeferredExecutor`, a sampling request can begin while an
    environment is still starting. The model can see that pending state, but
    needs a way to wait for the environment within the same turn before
    continuing.
    
    Environment startup is owned by Core, so the wait tool should use the
    same request-frozen `StepContext` that advertised the starting
    environment. This keeps tool registration and execution tied to the
    exact startup operation the model saw, even if live thread state later
    changes.
    
    Supersedes #29735.
    
    ## What
    
    - register `wait_for_environment` when the current `StepContext`
    contains starting environments
    - wait on the selected `StartingTurnEnvironment` shared resolution and
    return a bounded ready or failed result
    - rebuild the next request normally, removing the wait tool and exposing
    ready environment tools, or reporting the environment as unavailable
    after failure
    
    ## Testing
    
    - `just test -p codex-core deferred_executor_`
    - verifies the wait tool is replaced by environment-backed tools after
    startup
    - verifies startup failure removes both the wait tool and unavailable
    environment tools while notifying the model
  • Support thread-level originator overrides (#29477)
    ## Why
    
    Work(TPP) threads can be launched from the Desktop app, but if they all
    keep the Desktop app's default originator then downstream attribution
    cannot distinguish local Work launches from cloud-backed Work launches.
    `thread/start.serviceName` already carries that launch signal, while
    `SessionMeta.originator` is the durable thread-level value that survives
    resume and fork.
    
    This change converts the Desktop Work service names into an effective
    originator at thread creation time, persists that originator with the
    thread, and keeps using it for later model requests and memory writes.
    
    ## What changed
    
    - Map `CODEX_WORK_LOCAL` and `CODEX_WORK_CLOUD` service names to
    per-thread originators, while preserving
    `CODEX_INTERNAL_ORIGINATOR_OVERRIDE` as the highest-precedence override.
    - Persist the effective originator in `SessionMeta.originator`, read it
    back on resume/fork, and inherit the parent originator for subagent
    spawns when there is no persisted session metadata.
    - Handle truncated `SpawnAgentForkMode::LastNTurns` forks by falling
    back to the live parent originator when the forked history no longer
    includes `SessionMeta`.
    - Thread the per-thread originator through Responses headers,
    websocket/compaction request paths, thread-store creation, rollout
    metadata, and memory stage-one telemetry.
    
    ## Verification

  • core: reset context for token budget compaction (#29743)
    ## Why
    
    When `Feature::TokenBudget` is enabled, compaction should behave like
    `new_context`: start a fresh context window with the standard injected
    context, without asking the server to summarize old history and without
    carrying prior user or assistant messages into the next model request.
    
    This is still a compaction operation from the client lifecycle
    perspective. Manual `/compact` and auto-compaction should keep the same
    observable side effects that clients and hooks expect, including compact
    hooks and `TurnItem::ContextCompaction`.
    
    ## What changed
    
    - Added `compact_token_budget` to run token-budget manual and inline
    auto-compaction through a shared compaction lifecycle.
    - Split pending `new_context` requests from forced context-window
    startup: `take_new_context_window_request()` consumes pending requests,
    and `start_new_context_window()` installs a fresh context window.
    - Routed token-budget manual `/compact` and inline auto-compaction to
    install a fresh context window locally instead of calling server/local
    summarization.
    - Preserved compact lifecycle side effects for token-budget compaction
    by running pre/post compact hooks and emitting `ContextCompaction` item
    start/completion events.
    - Updated token-budget tests to assert fresh window IDs, absence of
    server-side compaction calls, dropped prior transcript messages/tool
    output after reset, and compact hook/item lifecycle behavior.
    
    ## Testing
    
    - `just test -p codex-core
    token_budget_context_uses_new_window_after_compaction`
    - `just test -p codex-core token_budget_compaction_runs_compact_hooks`

  • [codex] rename rollout budget error to session budget error (#29744)
    ## Summary
    
    - rename the rollout-budget exhaustion error from
    `RolloutBudgetExceeded` to `SessionBudgetExceeded`
    - expose the matching app-server v2 wire value as
    `sessionBudgetExceeded`
    - regenerate JSON/TypeScript schema fixtures and update the app-server
    docs and focused tests
    
    This is a naming-only follow-up to #29715 based on [Pavel's review
    suggestion](https://github.com/openai/codex/pull/29715#discussion_r3463183480).
    Runtime behavior is unchanged.

  • fix: scope context remaining to body window (#29665)
    ## Why
    
    With `model_auto_compact_token_limit_scope = "body_after_prefix"`, the
    persistent prefix should not count against the active body window.
    `get_context_remaining` and the token-budget reminder should report the
    same usable body-after-prefix window that auto-compaction uses, rather
    than the total token count since the session began.
    
    This is stacked on #29664 so the mechanical move from `turn.rs` is
    isolated from the behavior fix.
    
    ## What
    
    - Extends `ContextWindowTokenStatus` with `context_remaining_tokens`.
    - Updates `get_context_remaining` to use the shared context-window
    accounting.
    - Adds integration coverage for body-after-prefix reminder timing and
    `get_context_remaining` output.
    
    ## Testing
    
    - `just test -p codex-core body_after_prefix_window`
    - `just test -p codex-core auto_compact_body_after_prefix`
    - `just fix -p codex-core`
  • refactor: extract context window token status (#29664)
    ## Why
    
    This PR keeps the mechanical helper extraction separate from the
    behavior change in #29665. The follow-up needs the token-window
    accounting from `turn.rs` in another call path, but reviewing that is
    much easier when the helper extraction is separate from the semantic
    change.
    
    ## What
    
    - Adds `session/context_window.rs` with `ContextWindowTokenStatus`.
    - Moves the existing auto-compaction token-status calculation out of
    `session/turn.rs`.
    - Replaces the duplicated inline remaining-token calculation in
    `turn.rs` with `tokens_until_compaction()`.
    
    This PR is intended to be behavior-preserving. The
    `get_context_remaining` behavior change is stacked separately in #29665.
    
    ## Testing
    
    - `just test -p codex-core auto_compact_body_after_prefix`

  • protocol: separate app and exec RPC ownership (#29714)
    ## Why
    
    The app-server and exec-server expose separate JSON-RPC APIs, but
    exec-server currently sources its serialized protocol and envelope types
    through app-server-oriented code. Giving each API an explicit owner
    makes the crate boundary legible without introducing shared generic
    envelopes.
    
    ## What changed
    
    - Added `codex-exec-server-protocol` to own exec DTOs, process IDs, and
    JSON-RPC envelopes.
    - Updated exec-server clients, transports, handlers, and tests to use
    the new crate.
    - Exposed app-server's existing JSON-RPC types through a public `rpc`
    module while retaining root re-exports.
    - Preserved existing wire shapes, including exec `PathUri` behavior.
    
    ## Stack
    
    This is PR 1 of 6. Next: [PR
    #29721](https://github.com/openai/codex/pull/29721), which moves auth
    mode below the app wire boundary.
    
    ## Validation
    
    - Exec-server protocol and server coverage passed in the focused
    protocol test runs.
    - App-server protocol schema fixtures passed.
  • Load executor skills without host path conversion (#29626)
    ## Why
    
    After #28918, selected skill roots are `PathUri`, but the executor skill
    provider still converts them to the app-server host's `AbsolutePathBuf`.
    A foreign Windows root therefore cannot be discovered by a Unix host,
    and the inverse has the same problem.
    
    This PR keeps executor skill discovery and reads on the filesystem that
    owns the selected root while reusing the existing skill rules.
    
    ## What changed
    
    - Generalize the existing skill traversal to operate on `PathUri`
    through `ExecutorFileSystem`, preserving its depth, directory, symlink,
    and sibling-metadata concurrency behavior.
    - Add a small environment skill loader that reuses the shared discovery,
    frontmatter validation, dependency parsing, product policy, and
    prompt-visibility rules.
    - Keep the environment id and entrypoint `PathUri` in the skill catalog,
    then route `skills.read` back through the same environment filesystem.
    - Preserve the executor's path convention when deriving catalog handles,
    including literal backslashes in POSIX filenames.
    - Resolve plugin namespaces from nearby manifests through URI-native
    filesystem reads.
    - Cover foreign Windows roots, executor-owned reads, namespaces,
    metadata, policy, and path identity.
    
    ```text
    selected root (PathUri)
            |
            v
    shared discovery over ExecutorFileSystem
            |
            v
    environment-bound catalog entry --skills.read--> same ExecutorFileSystem
    ```
    
    No second filesystem abstraction or duplicate traversal implementation
    is introduced.

  • code-mode: Remove Session::is_alive() (#29732)
    Remove this unused API. This API is insidious in that it implies that
    alive state should be determinable from the caller, and implies that a
    preflight should indicate routing. Lets drop this, and handle errors
    correctly from a failed session in the future.
  • [codex] surface rollout budget exhaustion (#29715)
    ## Summary
    - surface shared rollout-budget exhaustion as
    `CodexErr::RolloutBudgetExceeded` instead of a generic interrupted turn
    - map it through the existing `CodexErrorInfo` and app-server v2
    `codexErrorInfo` path
    - keep local compaction from retrying after the shared rollout budget is
    exhausted
    
    This gives app-server clients a stable `rolloutBudgetExceeded` error
    they can classify without guessing from `status="interrupted"`.
    
    ## Tests
    - `just test -p codex-core rollout_budget`
  • [codex] define code mode host handshake protocol (#29515)
    ## Summary
    
    - add validated protocol-version, capability, and session identifier
    types
    - define explicit `ClientToHost` and `HostToClient` JSON envelopes for
    connection negotiation and session open/close acknowledgements
    - reject invalid states and unknown fields during decoding, with
    explicit wire-format and round-trip coverage
    
    ## Why
    
    This establishes the transport-neutral encoding shape needed to build
    and test the new code-mode host incrementally. Cell, tool callback, and
    failure-domain messages are intentionally deferred until their actors
    and behavior tests establish the required semantics.
    
    This is additive protocol scaffolding and does not change the current
    production code-mode implementation.
    
    ## Validation
  • Make selected plugin roots URI-native (#28918)
    ## Why
    
    Selected capability roots belong to the executor filesystem, not the
    app-server host. Converting their path strings into the host's native
    `Path` breaks whenever the two machines use different path conventions,
    such as a Windows executor behind a Unix app-server.
    
    This PR establishes `PathUri` as the selected-plugin boundary so the
    executor remains authoritative for its paths.
    
    ## What changed
    
    - Require `selectedCapabilityRoots[].location.path` to be a canonical
    `file:` URI and deserialize it directly as `PathUri`; native path
    strings are rejected.
    - Update the app-server schema, generated TypeScript, examples, and
    request coverage for the URI contract.
    - Keep selected roots, resolved plugin locations, manifest paths, and
    manifest resources as `PathUri`.
    - Inspect and read plugin roots and manifests only through the selected
    environment's `ExecutorFileSystem`.
    - Parse executor manifests with the shared URI-native parser from #29620
    instead of projecting them onto the host filesystem.
    - Enforce resource containment lexically and preserve the root URI's
    POSIX or Windows path convention.
    - Cover foreign Windows plugin roots and URI-native manifest resources.
    
    ```text
    thread/start
      selectedCapabilityRoots[].location.path = "file:///C:/plugins/demo"
                                  | PathUri
                                  v
                        ExecutorFileSystem
                                  |
                                  +--> plugin.json
                                  +--> manifest resources
    ```
    
    This PR stops at the shared selected-plugin representation. The next two
    PRs remove the remaining host-path projections in the skill and MCP
    consumers.

  • core: persist initial context window metadata (#29519)
    ## Why
    
    PR #29494 made context-window IDs visible to the model by wrapping the
    token-budget window payload in `<context_window>`, but rollout JSONL
    consumers still could not see the initial window identity by tailing the
    session file. Compacted rollout items carry window IDs only after
    compaction has happened, so a session with no compaction had no durable
    JSONL record for window 0.
    
    This change gives tailing consumers a stable initial-window record at
    session creation time.
    
    ## What Changed
    
    - Added `session_meta.context_window.window_id` for the initial
    context-window identity.
    - `CreateThreadParams` now requires `initial_window_id: String`, so
    thread-store callers cannot accidentally create new threads without
    window-0 metadata.
    - Live thread creation derives the persisted initial window ID from the
    same `AutoCompactWindowIds` used to initialize `SessionState`, keeping
    runtime state and JSONL metadata aligned.
    - Rollout reconstruction uses `session_meta.context_window.window_id` as
    the initial-window fallback and derives `window_number = 0`,
    `first_window_id = window_id`, and `previous_window_id = None`
    internally.
    - Fork reconstruction intentionally uses the same rollout reconstruction
    path; consumers that need to distinguish copied initial-window metadata
    can use the rollout `thread_id`.
    - Legacy compactions without `window_number` still use compaction-count
    fallback accounting instead of being reset to window 0 by the
    initial-window fallback.
    - Compacted rollout metadata still takes precedence once compaction
    records exist, preserving the richer chain fields there.
    
    ## JSONL Shape
    
    Real rollout JSONL is one object per line. This example is expanded for
    readability, but shows the new initial `session_meta.context_window`
    record followed by the existing compacted rollout item shape that also
    carries window IDs:
    
    ```jsonl
    {
      "timestamp": "2026-06-22T12:00:00.000Z",
      "type": "session_meta",
      "payload": {
        "session_id": "<THREAD_ID>",
        "id": "<THREAD_ID>",
        "timestamp": "2026-06-22T12:00:00.000Z",
        "cwd": "/repo",
        "originator": "codex",
        "cli_version": "0.0.0",
        "source": "cli",
        "model_provider": "<MODEL_PROVIDER>",
        "context_window": {
          "window_id": "<INITIAL_WINDOW_ID>"
        }
      }
    }
    ...
    {
      "timestamp": "2026-06-22T12:34:56.000Z",
      "type": "compacted",
      "payload": {
        "message": "<COMPACTION_SUMMARY>",
        "replacement_history": [
          "..."
        ],
        "window_number": 1,
        "first_window_id": "<INITIAL_WINDOW_ID>",
        "previous_window_id": "<INITIAL_WINDOW_ID>",
        "window_id": "<NEXT_WINDOW_ID>"
      }
    }
    ```
    
    The nested `context_window` object is intentional: it gives rollout
    consumers a stable namespace for context-window metadata while only
    writing the non-derivable initial `window_id`. For the initial window,
    `window_number`, `first_window_id`, and `previous_window_id` are derived
    internally instead of being written to the rollout.

  • path-uri: remove legacy path deserialization (#29158)
    ## Why
    
    I'd originally added `PathUri` legacy path deserialization thinking we'd
    want it for having `PathUri` in public app-server APIs. Since then we've
    added `LegacyAppPathString` to handle the messy conversions that we need
    for backcompat. It's confusing for `PathUri` to support deserializing
    legacy paths when we don't yet want to actually expose app-server
    callers or rollout storage to the new URI format.
    
    Stacked on top of #29472 to avoid breaking compatibility in case those
    types ended up stored somewhere for someone.
    
    ## What changed
    
    - Parse deserialized `PathUri` values exclusively as valid `file:` URIs.
    - Replace legacy acceptance coverage with rejection coverage for
    top-level filesystem paths and sandbox working directories.
    - Serialize CWDs in hand-built exec-server process requests as `PathUri`
    values.
  • core tests: rename automatic environment builder (#29728)
    ## Why
    
    Use a clearer name for what happens when this helper sets up a test
    environment.
    
    ## What
    
    - Rename the builder and its harness wrapper to use `auto_env` instead
    of `remote_env` because the helper will set up a local environment if
    configured by the build system.
  • test: branch on target OS instead of runner flavor (#29712)
    ## Why
    
    Core tests should branch on the executor's operating system, not on
    runner details such as Docker or Wine. This keeps platform behavior
    stable as new test backends are added and reserves Wine-specific skips
    for actual runner debt.
    
    ## What
    
    - Add `TestTargetOs` and target/host-aware skip helpers while keeping
    `TestEnvironment` internal.
    - Replace topology enum access with remote predicates and a narrow
    Docker accessor.
    - Migrate OS-semantic Wine skips, preserve runner-specific gaps, and
    document the skip taxonomy.
    
    ## Validation
    
    - `just test -p core_test_support`
    - `just test -p codex-core
    remote_test_env_can_connect_and_use_filesystem`
    - `bazel test //codex-rs/core:core-all-wine-exec-test
    --test_output=errors` reached test execution; unrelated existing
    view-image, path, and timing failures remain.
    - `just test -p codex-core` and `just test` reached broad test
    execution; this checkout has unrelated helper, sandbox, and timing
    failures.
  • code-mode: Rename codex_code_mode::CodeModeService (#29716)
    Mechanical rename of CodeModeService => InProcessCodeModeSession

  • feat(app-server): thread/turns/items/list -> thread/items/list (#29705)
    ## Description
    
    Rename the experimental app-server item pagination API from
    `thread/turns/items/list` to `thread/items/list` and make `turnId`
    optional. Clients can now page persisted items across a thread, or still
    filter to one turn when needed.
    
    ## What changed
    
    - Rename the request/response protocol types and JSON-RPC method to
    `ThreadItemsList*` / `thread/items/list`.
    - Pass optional `turnId` through to `ThreadStore::list_items`.
    - Update app-server docs and focused protocol/app-server tests.

  • [codex] Report the exec-server working directory (#29666)
    ## Summary
    
    - add the exec-server working directory to `environment/info` as an
    optional `PathUri`
    - populate it from the executor process's current directory
    - preserve compatibility with older responses that omit `cwd`
    
    ## Why
    
    Remote clients currently have no executor-native default working
    directory. This forces callers such as app-server-backend to assume
    `/workspace`, which fails for laptop environments. Reporting the cwd
    alongside the detected shell lets clients use the path convention and
    location of the actual executor.
    
    ## Impact
    
    This is backward-compatible: the new response field is optional, and
    clients can continue handling responses from older exec servers. A
    follow-up app-server-backend change will consume the value for cwd-less
    `command/exec` requests.
    
    ## Validation
    
    - `just test -p codex-exec-server` (275 passed, 2 skipped)
  • Decouple plugin manifest path resolution (#29620)
    ## Why
    
    Plugin manifests use the same schema whether the package lives on the
    host or in an executor. Only the path representation differs: host
    callers need native `Path` inputs and `AbsolutePathBuf` outputs, while
    executor callers need `PathUri` throughout.
    
    Maintaining separate parsing or resolver implementations would duplicate
    the manifest rules and allow them to drift. This PR instead makes
    URI-native resolution the single parsing path and keeps host conversion
    at the boundary.
    
    ## What changed
    
    - Make `parse_plugin_manifest_uri` the shared manifest parser and
    resolve every path-bearing field as `PathUri`.
    - Keep the existing host entrypoint as a thin adapter: convert its
    native root and manifest path to `PathUri`, run the shared parser, then
    map resources back to `AbsolutePathBuf`.
    - Expose `PluginManifest::try_map_resources` so callers can convert the
    generic resource type without duplicating manifest construction.
    - Resolve relative manifest paths using the root URI's convention:
    backslashes are separators for Windows roots and ordinary filename
    characters for POSIX roots.
    - Apply lexical containment after URI resolution, rejecting absolute
    paths and parent traversal outside the plugin root.
    - Make encoded backslashes fail containment only for Windows URIs;
    encoded `/` remains unsafe for every convention.
    - Use a host-native synthetic root for marketplace fallback manifests so
    the host adapter also works on Windows.
    
    ```text
    host Path --------> PathUri --\
                                  +--> one manifest parser --> PluginManifest<PathUri>

    host result: PluginManifest<PathUri> --> PluginManifest<AbsolutePathBuf>

  • feat(guardian): include connected account email in app reviews (#27045)
    ## Why
    
    auto review reviews Codex App tool calls using connector metadata such
    as the app ID, name, and description. That metadata does not identify
    the account behind the OAuth connection.
    
    For Google Drive, this means auto review cannot distinguish a Drive
    connection authenticated as `user@email.com` from a personal Drive
    account. Uploading work data can therefore look like a transfer to a
    personal destination even though the connector service already knows the
    authenticated account email.
    
    ## What changed
    
    - Read `_meta._codex_apps.connected_account_email` while resolving
    approval metadata for built-in Codex App tools.
    - Include the connected account email in the structured MCP tool action
    sent to auto review.
    - Trim empty values and omit the field when the connector link has no
    account email.
    - Update existing auto review request constructors and add coverage for
    request construction and JSON serialization.
    
    ## Security
    
    Only metadata from the trusted built-in `codex_apps` MCP server is
    accepted. Custom MCP servers cannot inject a connected account email
    into auto review reviews; the new regression test verifies that spoofed
    metadata is ignored.
    
    The email is used only in auto review's private review request. This
    change does not add it to model-visible tool descriptions, app-server
    approval events, or auto review assessment/review analytics.

    - record the same error classification on MCP tool-call spans while

    ## Scope
    
    - no changes to MCP routing, retries, tool behavior, configuration, or

  • core: use current step environments for tools (#29547)
    ## Why
    
    With deferred executors, an environment can become ready between two
    sampling requests in the same turn. The model-visible environment
    update, advertised tools, and eventual tool execution must all describe
    the same request-time view.
    
    Otherwise, a request built while only environment B is ready can
    advertise a tool without an `environment_id`; if higher-priority
    environment A becomes ready before execution, that call could silently
    run in A instead.
    
    This PR is stacked on #29527.
    
    ## Design
    
    `run_turn` captures one `Arc<StepContext>` at each sampling-request
    boundary. That step owns the request's `TurnContext` and environment
    snapshot.
    
    - World-state environment updates and tool planning borrow that same
    step.
    - `ToolCallRuntime` retains the `Arc` while asynchronous tool calls
    execute.
    - `ToolInvocation` carries the step to handlers; its temporary `turn`
    compatibility field is derived from the same object.
    - `ToolRouter` does not retain `StepContext`; it only uses it while
    constructing the request's tool set.
    - With `DeferredExecutor` disabled, step capture keeps using the
    environments frozen at turn start.
    
    Simply: every sampling request gets one consistent picture of its
    environments, from what the model sees through where its tool calls run.
    
    ## What changed
    
    - Build environment-dependent tool specs from the current request's
    `StepContext`.
    - Use that same step for unified exec, legacy shell, `apply_patch`,
    `view_image`, and `request_permissions` execution.
    - Hide environment-backed tools, including `request_permissions`, while
    no environment is attached.
    - Resolve legacy shell paths and metadata from the selected step
    environment instead of the stale turn-start environment.
    - Capture explicit steps at non-turn-loop boundaries such as compaction,
    prompt debug, and startup prewarm.
    - Reconcile prompt-debug history from the same step used to build its
    tools.
    
    ## Follow-up
    
    - Bind yielded code-mode cells to the tool runtime that created them, so
    nested calls made after yielding continue to use the originating
    request's `StepContext`.
    
    ## Test plan
    
    - `just test -p codex-core
    deferred_executor_updates_context_and_tools_after_startup`
    - `just test -p codex-core
    environment_count_controls_environment_backed_tools`

  • [codex] Fix stale approval policy in MCP test (#29696)
    ## Summary
    
    - replace the stale `AskForApproval::OnFailure` reference in the MCP
    connection manager test with `AskForApproval::OnRequest`
    - restore `codex-mcp` test compilation after `OnFailure` was removed in
    #28418
    
    ## Root cause
    
    The test was added on main after the approval-policy removal branch had
    already updated the other references, so the newly added call site was
    missed when #28418 merged.
    
    ## Validation
    
    - `just test -p codex-mcp` (90 passed)
    - `just fmt`
  • core: resolve view_image paths in selected environment (#29526)
    ## Why
    
    view_image needs to support foreign OS remote executors.
    
    ## What
    
    - resolve image paths against the selected environment as `PathUri` and
    read them through that environment's filesystem
    - keep app-server's public path field wire-compatible as
    `LegacyAppPathString`, with purpose-specific UI rendering
    - cover relative and absolute target-native paths in the core
    integration test and run the full `view_image` suite under wine-exec
    without skips
  • [codex] allow image generation with provider auth (#29513)
    ## Summary
    
    - allow the native Responses API `image_generation` tool when the active
    provider carries CCA's non-empty `x-openai-actor-authorization` header
    - preserve the Codex-managed ChatGPT auth path, scoped to providers that
    actually require OpenAI auth
    - keep generic custom providers excluded, including when unrelated
    ChatGPT credentials are cached
    - retain the existing feature, provider-capability, and
    image-input-modality gates
    
    ## Why
    
    CCA authenticates its inference requests through the active provider's
    `x-openai-actor-authorization` and `ChatGPT-Account-ID` headers, so it
    does not have a Codex-managed login session. The previous gate therefore
    hid the native hosted image-generation tool despite an authenticated
    codex-backend path.
    
    This change is intentionally limited to the native hosted tool. It adds
    no extension, MCP, plugin-service, session-source, token plumbing, or
    new provider configuration surface.
    
    ## Tests
    
    - `cargo test -p codex-core
    hosted_tools_follow_provider_auth_model_and_config_gates`
    - `cargo fmt --all -- --check`
    - `git diff --check origin/main`
  • [codex] Preserve proxy state for filesystem sandbox helpers (#29671)
    ## Why
    
    Filesystem helpers intentionally run with a minimal environment that
    excludes proxy variables. After filesystem operations started using the
    Windows sandbox wrapper, the wrapper derived an empty proxy
    configuration from that helper environment and compared it with the
    persistent sandbox setup marker. When the marker contained proxy ports,
    every filesystem operation appeared to require a firewall update, which
    could launch elevated setup, show a UAC or loader dialog, and fail
    operations such as `apply_patch` with error 1223.
    
    Filesystem helpers do not use network access, so they should preserve
    the proxy/firewall state established by normal sandboxed process
    launches.
    
    ## What changed
    
    - Add an explicit Windows sandbox proxy-settings mode for reconciling or
    preserving persistent proxy state.
    - Use preserve mode for filesystem helpers while normal process launches
    continue to reconcile proxy settings from their environment.
    - Carry the selected proxy state consistently through setup validation,
    elevated setup, and non-elevated ACL refreshes.
    - Cover wrapper argument propagation and marker-derived proxy
    preservation.
    
    ## Validation
    
    - `cargo build -p codex-cli --bin codex`
    - `just test -p codex-windows-sandbox
    preserving_proxy_settings_uses_the_existing_marker`
    - `just test -p codex-windows-sandbox windows_wrapper_args_round_trip`
    - `just test -p codex-windows-sandbox
    setup_request_prefers_explicit_proxy_settings`
    - `just test -p codex-sandboxing transform_for_direct_spawn_windows`
    - `just test -p codex-exec-server fs_sandbox::tests`
    - Ran the same sandboxed `fs/writeFile` reproduction against published
    `0.142.0-alpha.6` and the new CLI. The published CLI launched elevated
    setup and failed with `ShellExecuteExW ... 1223`; the new CLI completed
    without elevation.
    
    Related to #28359.
  • Separate local and remote plugin analytics IDs (#29495)
    ## Why
    
    Plugin analytics overloaded `plugin_id`: most events used the Codex
    `<plugin>@<marketplace>` identity, while remote install events used the
    backend plugin ID. That makes the same field change meaning across event
    types and complicates downstream identity resolution.
    
    This change makes the contract unambiguous:
    
    - `plugin_id`: the local Codex `<plugin>@<marketplace>` identity, when
    resolved
    - `remote_plugin_id`: the backend plugin identity, when available
    
    For a remote install failure that happens before plugin details resolve,
    `plugin_id` is `null` and `remote_plugin_id` remains populated.
    
    ## What changed
    
    All six plugin analytics events use the same identity contract:
    
    - `codex_plugin_installed`
    - `codex_plugin_install_failed`
    - `codex_plugin_uninstalled`
    - `codex_plugin_enabled`
    - `codex_plugin_disabled`
    - `codex_plugin_used`
    
    Remote identity is resolved from the current installed-plugin snapshot
    first, with persisted install metadata as fallback. The telemetry
    metadata type keeps local identity optional for failures that occur
    before remote details are available.
    
    The app-server test client's manual analytics smokes now find remote
    mutation events through `remote_plugin_id` and validate that `plugin_id`
    remains local.
    
    ## Remote uninstall
    
    Resolve and capture telemetry metadata before removing the local plugin
    cache, then emit `codex_plugin_uninstalled` after the backend confirms
    success. The event is also emitted when backend uninstall succeeds but
    local cache cleanup reports `CacheRemove`.
    
    If a concurrent remote-cache refresh removes the local bundle before
    telemetry capture, the already-fetched remote plugin detail supplies
    fallback capability metadata.
    
    ## Validation
    
    - `just test -p codex-analytics` — 82 passed
    - `just test -p codex-core-plugins` — 271 passed
    - `just test -p codex-app-server-test-client` — 5 passed
    - `just test -p codex-plugin` — 3 passed
    - `just test -p codex-app-server plugin_install` — 37 passed
    - `just test -p codex-app-server plugin_uninstall` — 10 passed
    
    The production app-server install/uninstall flow was also exercised
    against `plugins~Plugin_f1b845ac33888191ac156169c58733c2`
    (`build-ios-apps@openai-curated-remote`), and the plugin's original
    uninstalled state was restored.
  • Keep managed MITM CA private keys in proxy memory (#29013)
    ## Why
    
    The managed MITM trust bundle must be readable by sandboxed commands.
    Persisting its sibling CA private key under `$CODEX_HOME/proxy`
    therefore requires a deny-read sandbox rule, but the Windows unelevated
    backend rejects deny-read paths and WSL1's legacy Landlock path cannot
    enforce that rule.
    
    A persistent OS credential store also does not provide the same
    cross-platform boundary from other processes running as the same user.
    Keeping the signer inside the network proxy process avoids both
    problems: ordinary sandbox setup stays independent of CA-key state, and
    no private signing key is exposed through the filesystem or a persistent
    credential record.
    
    ## What
    
    - generate one managed CA per proxy process and retain its private
    signer only in proxy memory
    - emit only content-addressed public CA certificates and trust bundles
    under `$CODEX_HOME/proxy`
    - hold a cross-process lease for each active public certificate and
    prune artifacts from inactive proxy processes
    - keep all CA ownership in `codex-network-proxy`; no `codex-core` or
    sandbox-policy changes
    - validate generated trust-bundle paths by their content hash
    - keep the public bundle readable by sandboxed commands on Windows,
    WSL1, macOS, and Linux
    
    The independent startup custom-CA follow-up is #29014.
    
    ## Validation
    
    - `CODEX_HOME=/private/tmp/codex-test-home-network-proxy just test -p
    codex-network-proxy` (179 tests)
    - `just bazel-lock-check`
    - `just fix -p codex-network-proxy`
    - `just fmt`

  • core: add extra metadata field to Thread struct (#29675)
    # Summary
    
    Adds a field Thread.extras that can be used to hold arbitrary metadata
    specific to a given thread.
  • chore(core) rm AskForApproval::OnFailure (#28418)
    ## Summary
    Deletes the OnFailure variant of the `AskForApproval` enum. This option
    has been deprecated since #11631.
    
    ## Testing
    - [x] Tests pass
  • Prepare managed network sandbox context (#29456)
    ## Why
    
    Managed network configures commands to use local HTTP and SOCKS proxies.
    For commands delegated to the exec server, the proxy environment and the
    sandbox policy were prepared separately. On macOS, that meant a command
    could receive `HTTPS_PROXY=http://127.0.0.1:43123` while Seatbelt still
    denied access to port `43123`.
    
    ## What changed
    
    `NetworkProxy` now prepares the command environment and sandbox context
    together from the same runtime snapshot:
    
    ```text
    Prepared managed network
    ├── command environment: HTTPS_PROXY=http://127.0.0.1:43123
    └── sandbox context: allow outbound to 127.0.0.1:43123
    ```
    
    That context travels with remote exec requests. The exec server
    preserves the managed proxy and CA environment, and macOS Seatbelt
    allows only the prepared loopback proxy ports without enabling broad
    network access or local binding.
    
    The protocol field is optional and the existing enforcement flag remains
    in place, preserving compatibility with callers that do not send the new
    context.
  • app-server: document thread and turn IDs are UUID7 (#27714)
    It's actually a very nice property that these are UUID7s, so documenting
    them so we think twice before changing it away from UUID7s in the
    future.
  • Handle additional tools in rollout persistence metrics (#29669)
    ## Why
    
    The rollout persistence metrics added on current `main` exhaustively
    match `ResponseItem`, but omit `ResponseItem::AdditionalTools`. That
    prevents `codex-rollout` and downstream targets from compiling across
    Cargo and Bazel builds.
    
    ## What
    
    Map `ResponseItem::AdditionalTools` to the `response.additional_tools`
    metric label, consistent with the existing exact-variant labels.
    
    ## Validation
    
    - `just test -p codex-rollout` (76 passed)
    - `just fix -p codex-rollout`
