  • chore: wire through plugin policies + category from marketplace.json (#14305)
    wire plugin marketplace metadata through app-server endpoints:
    - `plugin/list` has `installPolicy` and `authPolicy`
    - `plugin/install` has plugin-level `authPolicy`
    
    `plugin/install` also now enforces `NOT_AVAILABLE` `installPolicy` when
    installing.
    
    
    added tests.
  • Show spawned agent model and effort in TUI (#14273)
    - include the requested sub-agent model and reasoning effort in the
    spawn begin event\n- render that metadata next to the spawned agent name
    and role in the TUI transcript

  • chore: add a separate reject-policy flag for skill approvals (#14271)
    ## Summary
    - add `skill_approval` to `RejectConfig` and the app-server v2
    `AskForApproval::Reject` payload so skill-script prompts can be
    configured independently from sandbox and rule-based prompts
    - update Unix shell escalation to reject prompts based on the actual
    decision source, keeping prefix rules tied to `rules`, unmatched command
    fallbacks tied to `sandbox_approval`, and skill scripts tied to
    `skill_approval`
    - regenerate the affected protocol/config schemas and expand
    unit/integration coverage for the new flag and skill approval behavior
  • feat: Add additional macOS Sandbox Permissions for Launch Services, Contacts, Reminders (#14155)

    - Launch Services
    - Contacts
    - Reminders
  • Add ephemeral flag support to thread fork (#14248)
    ### Summary
    This PR adds first-class ephemeral support to thread/fork, bringing it
    in line with thread/start. The goal is to support one-off completions on
    full forked threads without persisting them as normal user-visible
    threads.

  • app-server: propagate nested experimental gating for AskForApproval::Reject (#14191)
    ## Summary
    This change makes `AskForApproval::Reject` gate correctly anywhere it
    appears inside otherwise-stable app-server protocol types.
    
    Previously, experimental gating for `approval_policy: Reject` was
    handled with request-specific logic in `ClientRequest` detection. That
    covered a few request params types, but it did not generalize to other
    nested uses such as `ProfileV2`, `Config`, `ConfigReadResponse`, or
    `ConfigRequirements`.
    
    This PR replaces that ad hoc handling with a generic nested experimental
    propagation mechanism.
    
    ## Testing

    enabled:

  • feat: Allow sync with remote plugin status. (#14176)
    Add forceRemoteSync to plugin/list.
    When it is set to True, we will sync the local plugin status with the
    remote one (backend-api/plugins/list).
  • Use realtime transcript for handoff context (#14132)
    - collect input/output transcript deltas into active handoff transcript
    state
    - attach and clear that transcript on each handoff, and regenerate
    schema/tests
  • Implemented thread-level atomic elicitation counter for stopwatch pausing (#12296)
    ### Purpose
    While trying to build out CLI-Tools for the agent to use under skills we
    have found that those tools sometimes need to invoke a user elicitation.
    These elicitations are handled out of band of the codex app-server but
    need to indicate to the exec manager that the command running is not
    going to progress on the usual timeout horizon.
    
    ### Example
    Model calls universal exec:
    `$ download-credit-card-history --start-date 2026-01-19 --end-date
    2026-02-19 > credit_history.jsonl`
    
    download-cred-card-history might hit a hosted/preauthenticated service
    to fetch data. That service might decide that the request requires an
    end user approval the access to the personal data. It should be able to
    signal to the running thread that the command in question is blocked on
    user elicitation. In that case we want the exec to continue, but the
    timeout to not expire on the tool call, essentially freezing time until
    the user approves or rejects the command at which point the tool would
    signal the app-server to decrement the outstanding elicitation count.
    Now timeouts would proceed as normal.
    
    ### What's Added
    
    - New v2 RPC methods:
        - thread/increment_elicitation
        - thread/decrement_elicitation
    - Protocol updates in:
        - codex-rs/app-server-protocol/src/protocol/common.rs
        - codex-rs/app-server-protocol/src/protocol/v2.rs
    - App-server handlers wired in:
        - codex-rs/app-server/src/codex_message_processor.rs
    
    ### Behavior
    
    - Counter starts at 0 per thread.
    - increment atomically increases the counter.
    - decrement atomically decreases the counter; decrement at 0 returns
    invalid request.
    - Transition rules:
    - 0 -> 1: broadcast pause state, pausing all active stopwatches
    immediately.
        - \>0 -> >0: remain paused.
        - 1 -> 0: broadcast unpause state, resuming stopwatches.
    - Core thread/session logic:
        - codex-rs/core/src/codex_thread.rs
        - codex-rs/core/src/codex.rs
        - codex-rs/core/src/mcp_connection_manager.rs
    
    ### Exec-server stopwatch integration
    
    - Added centralized stopwatch tracking/controller:
        - codex-rs/exec-server/src/posix/stopwatch_controller.rs
    - Hooked pause/unpause broadcast handling + stopwatch registration:
        - codex-rs/exec-server/src/posix/mcp.rs
        - codex-rs/exec-server/src/posix/stopwatch.rs
        - codex-rs/exec-server/src/posix.rs
  • fix(core) default RejectConfig.request_permissions (#14165)
    ## Summary
    Adds a default here so existing config deserializes
    
    ## Testing
    - [x] Added a unit test
  • start of hooks engine (#13276)
    (Experimental)
    
    This PR adds a first MVP for hooks, with SessionStart and Stop
    
    The core design is:
    
    - hooks live in a dedicated engine under codex-rs/hooks
    - each hook type has its own event-specific file
    - hook execution is synchronous and blocks normal turn progression while
    running
    - matching hooks run in parallel, then their results are aggregated into
    a normalized HookRunSummary
    
    On the AppServer side, hooks are exposed as operational metadata rather
    than transcript-native items:
    
    - new live notifications: hook/started, hook/completed
    - persisted/replayed hook results live on Turn.hookRuns
    - we intentionally did not add hook-specific ThreadItem variants
    
    Hooks messages are not persisted, they remain ephemeral. The context
    changes they add are (they get appended to the user's prompt)
  • feat(approvals) RejectConfig for request_permissions (#14118)
    ## Summary
    We need to support allowing request_permissions calls when using
    `Reject` policy

    />
    
    Note that this is a backwards-incompatible change for Reject policy. I'm
    not sure if we need to add a default based on our current use/setup

  • Stabilize protocol schema fixture generation (#13886)
    ## What changed
    - TypeScript schema fixture generation now goes through in-memory tree
    helpers rather than a heavier on-disk generation path.
    - The comparison logic normalizes generated banner and path differences
    that are not semantically relevant to the exported schema.
    - TypeScript and JSON fixture coverage are split into separate tests,
    and the expensive schema-export tests are serialized in `nextest`.
    
    ## Why this fixes the flake
    - The original fixture coverage mixed several heavy codegen paths into
    one monolithic test and then compared generated output that included
    incidental banner/path differences.
    - On Windows CI, that combination created both runtime pressure and
    output variance unrelated to the schema shapes we actually care about.
    - Splitting the coverage isolates failures by format, in-memory
    generation reduces filesystem churn, normalization strips generator
    noise, and serializing the heavy tests removes parallel resource
    contention.
    
    ## Scope
    - Production helper change plus test changes.
  • chore: plugin/uninstall endpoint (#14111)
    add `plugin/uninstall` app-server endpoint to fully rm plugin from
    plugins cache dir and rm entry from user config file.
    
    plugin-enablement is session-scoped, so uninstalls are only picked up in
    new sessions (like installs).
    
    added tests.
  • Add request permissions tool (#13092)
    Adds a built-in `request_permissions` tool and wires it through the
    Codex core, protocol, and app-server layers so a running turn can ask
    the client for additional permissions instead of relying on a static
    session policy.
    
    The new flow emits a `RequestPermissions` event from core, tracks the
    pending request by call ID, forwards it through app-server v2 as an
    `item/permissions/requestApproval` request, and resumes the tool call
    once the client returns an approved subset of the requested permission
    profile.
  • app-server: include experimental skill metadata in exec approval requests (#13929)
    ## Summary
    
    This change surfaces skill metadata on command approval requests so
    app-server clients can tell when an approval came from a skill script
    and identify the originating `SKILL.md`.
    
    - add `skill_metadata` to exec approval events in the shared protocol
    - thread skill metadata through core shell escalation and delegated
    approval handling for skill-triggered approvals
    - expose the field in app-server v2 as experimental `skillMetadata`
    - regenerate the JSON/TypeScript schemas and cover the new field in
    protocol, transport, core, and TUI tests
    
    ## Why
    
    Skill-triggered approvals already carry skill context inside core, but
    app-server clients could not see which skill caused the prompt. Sending
    the skill metadata with the approval request makes it possible for
    clients to present better approval UX and connect the prompt back to the
    relevant skill definition.

  • [app-server] Support hot-reload user config when batch writing config. (#13839)
    - [x] Support hot-reload user config when batch writing config.
  • Add guardian approval MVP (#13692)
    ## Summary
    - add the guardian reviewer flow for `on-request` approvals in command,
    patch, sandbox-retry, and managed-network approval paths
    - keep guardian behind `features.guardian_approval` instead of exposing
    a public `approval_policy = guardian` mode
    - route ordinary `OnRequest` approvals to the guardian subagent when the
    feature is enabled, without changing the public approval-mode surface
    
    ## Public model
    - public approval modes stay unchanged
    - guardian is enabled via `features.guardian_approval`
    - when that feature is on, `approval_policy = on-request` keeps the same
    approval boundaries but sends those approval requests to the guardian
    reviewer instead of the user
    - `/experimental` only persists the feature flag; it does not rewrite
    `approval_policy`
    - CLI and app-server no longer expose a separate `guardian` approval
    mode in this PR
    
    ## Guardian reviewer
    - the reviewer runs as a normal subagent and reuses the existing
    subagent/thread machinery
    - it is locked to a read-only sandbox and `approval_policy = never`
    - it does not inherit user/project exec-policy rules
    - it prefers `gpt-5.4` when the current provider exposes it, otherwise
    falls back to the parent turn's active model
    - it fail-closes on timeout, startup failure, malformed output, or any
    other review error
    - it currently auto-approves only when `risk_score < 80`
    
    ## Review context and policy
    - guardian mirrors `OnRequest` approval semantics rather than
    introducing a separate approval policy
    - explicit `require_escalated` requests follow the same approval surface
    as `OnRequest`; the difference is only who reviews them
    - managed-network allowlist misses that enter the approval flow are also
    reviewed by guardian
    - the review prompt includes bounded recent transcript history plus
    recent tool call/result evidence
    - transcript entries and planned-action strings are truncated with
    explicit `<guardian_truncated ... />` markers so large payloads stay
    bounded
    - apply-patch reviews include the full patch content (without
    duplicating the structured `changes` payload)
    - the guardian request layout is snapshot-tested using the same
    model-visible Responses request formatter used elsewhere in core
    
    ## Guardian network behavior
    - the guardian subagent inherits the parent session's managed-network
    allowlist when one exists, so it can use the same approved network
    surface while reviewing
    - exact session-scoped network approvals are copied into the guardian
    session with protocol/port scope preserved
    - those copied approvals are now seeded before the guardian's first turn
    is submitted, so inherited approvals are available during any immediate
    review-time checks
    
    ## Out of scope / follow-ups
    - the sandbox-permission validation split was pulled into a separate PR
    and is not part of this diff
    - a future follow-up can enable `serde_json` preserve-order in
    `codex-core` and then simplify the guardian action rendering further

  • app-server: require absolute cwd for windowsSandbox/setupStart (#13833)
    ## Summary
    - require windowsSandbox/setupStart.cwd to be an AbsolutePathBuf
    - reject relative cwd values at request parsing instead of normalizing
    them later in the setup flow
    - add RPC-layer coverage for relative cwd rejection and update the
    checked-in protocol schemas/docs
    
    ## Why
    windowsSandbox/setupStart was carrying the client-provided cwd as a raw
    PathBuf for command_cwd while config derivation normalized the same
    value into an absolute policy_cwd.
    
    That left room for relative-path ambiguity in the setup path, especially
    for inputs like cwd: "repo". Making the RPC accept only absolute paths
    removes that split entirely: the handler now receives one
    already-validated absolute path and uses it for both config derivation
    and setup.
    
    This keeps the trust model unchanged. Trusted clients could already
    choose the session cwd; this change is only about making the setup RPC
    reject relative paths so command_cwd and policy_cwd cannot diverge.
    
    ## Testing
    - cargo test -p codex-app-server windows_sandbox_setup (run locally by
    user)
    - cargo test -p codex-app-server-protocol windows_sandbox (run locally
    by user)
  • feat(app-server-protocol): address naming conflicts in json schema exporter (#13819)
    This fixes a schema export bug where two different `WebSearchAction`
    types were getting merged under the same name in the app-server v2 JSON
    schema bundle.
    
    The problem was that v2 thread items use the app-server API's
    `WebSearchAction` with camelCase variants like `openPage`, while
    `ThreadResumeParams.history` and
    `RawResponseItemCompletedNotification.item` pull in the upstream
    `ResponseItem` graph, which uses the Responses API snake_case shape like
    `open_page`. During bundle generation we were flattening nested
    definitions into the v2 namespace by plain name, so the later definition
    could silently overwrite the earlier one.
    
    That meant clients generating code from the bundled schema could end up
    with the wrong `WebSearchAction` definition for v2 thread history. In
    practice this shows up on web search items reconstructed from rollout
    files with persisted extended history.
    
    This change does two things:
    - Gives the upstream Responses API schema a distinct JSON schema name:
    `ResponsesApiWebSearchAction`
    - Makes namespace-level schema definition collisions fail loudly instead
    of silently overwriting

  • feat: Add curated plugin marketplace + Metadata Cleanup. (#13712)
    1. Add a synced curated plugin marketplace and include it in marketplace
    discovery.
    2. Expose optional plugin.json interface metadata in plugin/list
    3. Tighten plugin and marketplace path handling using validated absolute
    paths.
    4. Let manifests override skill, MCP, and app config paths.
    5. Restrict plugin enablement/config loading to the user config layer so
    plugin enablement is at global level
  • feat: structured plugin parsing (#13711)
    #### What
    
    Add structured `@plugin` parsing and TUI support for plugin mentions.
    
    - Core: switch from plain-text `@display_name` parsing to structured
    `plugin://...` mentions via `UserInput::Mention` and
    `[$...](plugin://...)` links in text, same pattern as apps/skills.
    - TUI: add plugin mention popup, autocomplete, and chips when typing

    Builds on #13510. Currently clients have to build their own `id` via
    `plugin@marketplace` and filter plugins to show by `enabled`, but we
    will add `id` and `available` as fields returned from `plugin/list`
    soon.

    chatgpt, and return list of all apps that are not. clients can use this
    list to trigger auth workflows as needed.
    
    checks are best effort based on `codex_apps` loading, much like
    `app/list`.
    
    #### Tests

  • fix: accept two macOS automation input shapes for approval payload compatibility (#13683)
    ## Summary
    This PR:
    1. fixes a deserialization mismatch for macOS automation permissions in
    approval payloads by making core parsing accept both supported wire
    shapes for bundle IDs.
    2. added `#[serde(default)]` to `MacOsSeatbeltProfileExtensions` so
    omitted fields deserialize to secure defaults.
    
    
    ## Why this change is needed
    `MacOsAutomationPermission` uses `#[serde(try_from =
    "MacOsAutomationPermissionDe")]`, so deserialization is controlled by
    `MacOsAutomationPermissionDe`. After we aligned v2
    `additionalPermissions.macos.automations` to the core shape, approval
    payloads started including `{ "bundle_ids": [...] }` in some paths.
    `MacOsAutomationPermissionDe` previously accepted only `"none" | "all"`
    or a plain array, so object-shaped bundle IDs failed with `data did not
    match any variant of untagged enum MacOsAutomationPermissionDe`. This
    change restores compatibility by accepting both forms while preserving
    existing normalization behavior (trim values and map empty bundle lists
    to `None`).
    
    ## Validation
    
    saw this error went away when running
    ```
    cargo run -p codex-app-server-test-client -- \
        --codex-bin ./target/debug/codex \

  • support plugin/list. (#13540)
    Introduce a plugin/list which reads from local marketplace.json.
    Also update the signature for plugin/install.
  • core/protocol: add structured macOS additional permissions and merge them into sandbox execution (#13499)
    ## Summary
    - Introduce strongly-typed macOS additional permissions across
    protocol/core/app-server boundaries.
    - Merge additional permissions into effective sandbox execution,
    including macOS seatbelt profile extensions.
    - Expand docs, schema/tool definitions, UI rendering, and tests for
    `network`, `file_system`, and `macos` additional permissions.
  • add @plugin mentions (#13510)
    ## Note-- added plugin mentions via @, but that conflicts with file
    mentions
    
    depends and builds upon #13433.
    
    - introduces explicit `@plugin` mentions. this injects the plugin's mcp
    servers, app names, and skill name format into turn context as a dev
    message.
    - we do not yet have UI for these mentions, so we currently parse raw
    text (as opposed to skills and apps which have UI chips, autocomplete,
    etc.) this depends on a `plugins/list` app-server endpoint we can feed
    the UI with, which is upcoming
    - also annotate mcp and app tool descriptions with the plugin(s) they
    come from. this gives the model a first class way of understanding what
    tools come from which plugins, which will help implicit invocation.
    
    ### Tests
    Added and updated tests, unit and integration. Also confirmed locally a
    raw `@plugin` injects the dev message, and the model knows about its
    apps, mcps, and skills.
  • feat(app-server): support mcp elicitations in v2 api (#13425)
    This adds a first-class server request for MCP server elicitations:
    `mcpServer/elicitation/request`.
    
    Until now, MCP elicitation requests only showed up as a raw
    `codex/event/elicitation_request` event from core. That made it hard for
    v2 clients to handle elicitations using the same request/response flow
    as other server-driven interactions (like shell and `apply_patch`
    tools).
    
    This also updates the underlying MCP elicitation request handling in
    core to pass through the full MCP request (including URL and form data)
    so we can expose it properly in app-server.
    
    ### Why not `item/mcpToolCall/elicitationRequest`?
    This is because MCP elicitations are related to MCP servers first, and
    only optionally to a specific MCP tool call.
    
    In the MCP protocol, elicitation is a server-to-client capability: the
    server sends `elicitation/create`, and the client replies with an
    elicitation result. RMCP models it that way as well.
    
    In practice an elicitation is often triggered by an MCP tool call, but
    not always.
    
    ### What changed
    - add `mcpServer/elicitation/request` to the v2 app-server API
    - translate core `codex/event/elicitation_request` events into the new
    v2 server request
    - map client responses back into `Op::ResolveElicitation` so the MCP
    server can continue
    - update app-server docs and generated protocol schema
    - add an end-to-end app-server test that covers the full round trip
    through a real RMCP elicitation flow
    - The new test exercises a realistic case where an MCP tool call
    triggers an elicitation, the app-server emits
    mcpServer/elicitation/request, the client accepts it, and the tool call
    resumes and completes successfully.
    
    ### app-server API flow
    - Client starts a thread with `thread/start`.
    - Client starts a turn with `turn/start`.
    - App-server sends `item/started` for the `mcpToolCall`.
    - While that tool call is in progress, app-server sends
    `mcpServer/elicitation/request`.
    - Client responds to that request with `{ action: "accept" | "decline" |
    "cancel" }`.
    - App-server sends `serverRequest/resolved`.
    - App-server sends `item/completed` for the mcpToolCall.
    - App-server sends `turn/completed`.
    - If the turn is interrupted while the elicitation is pending,
    app-server still sends `serverRequest/resolved` before the turn
    finishes.

  • feat(app-server-test-client): OTEL setup for tracing (#13493)
    ### Overview
    This PR:
    - Updates `app-server-test-client` to load OTEL settings from
    `$CODEX_HOME/config.toml` and initializes its own OTEL provider.
    - Add real client root spans to app-server test client traces.
    
    This updates `codex-app-server-test-client` so its Datadog traces
    reflect the full client-driven flow instead of a set of server spans
    stitched together under a synthetic parent.
    
    Before this change, the test client generated a fake `traceparent` once
    and reused it for every JSON-RPC request. That kept the requests in one
    trace, but there was no real client span at the top, so Datadog ended up
    showing the sequence in a slightly misleading way, where all RPCs were
    anchored under `initialize`.
    
    Now the test client:
    - loads OTEL settings from the normal Codex config path, including
    `$CODEX_HOME/config.toml` and existing --config overrides
    - initializes tracing the same way other Codex binaries do when trace
    export is enabled
    - creates a real client root span for each scripted command
    - creates per-request client spans for JSON-RPC methods like
    `initialize`, `thread/start`, and `turn/start`
    - injects W3C trace context from the current client span into
    request.trace instead of reusing a fabricated carrier
    
    This gives us a cleaner trace shape in Datadog:
    - one trace URL for the whole scripted flow
    - a visible client root span
    - proper client/server parent-child relationships for each app-server
    request
  • allow apps to specify cwd for sandbox setup. (#13484)
    The electron app doesn't start up the app-server in a particular
    workspace directory.
    So sandbox setup happens in the app-installed directory instead of the
    project workspace.
    
    This allows the app do specify the workspace cwd so that the sandbox
    setup actually sets up the ACLs instead of exiting fast and then having
    the first shell command be slow.
  • image-gen-core (#13290)
    Core tool-calling for image-gen, handles requesting and receiving logic
    for images using response API
  • chore: Nest skill and protocol network permissions under network.enabled (#13427)
    ## Summary
    
    Changes the permission profile shape from a bare network boolean to a
    nested object.
    
    Before:
    
    ```yaml
    permissions:
      network: true
    ```
    
    After:
    
    ```yaml
    permissions:
      network:
        enabled: true
    ```
    
    This also updates the shared Rust and app-server protocol types so
    `PermissionProfile.network` is no longer `Option<bool>`, but
    `Option<NetworkPermissions>` with `enabled: Option<bool>`.
    
    ## What Changed
    
    - Updated `PermissionProfile` in `codex-rs/protocol/src/models.rs`:
    - `pub network: Option<bool>` -> `pub network:
    Option<NetworkPermissions>`
    - Added `NetworkPermissions` with:
      - `pub enabled: Option<bool>`
    - Changed emptiness semantics so `network` is only considered empty when
    `enabled` is `None`
    - Updated skill metadata parsing to accept `permissions.network.enabled`
    - Updated core permission consumers to read
    `network.enabled.unwrap_or(false)` where a concrete boolean is needed
    - Updated app-server v2 protocol types and regenerated schema/TypeScript
    outputs
    - Updated docs to mention `additionalPermissions.network.enabled`
  • config: enforce enterprise feature requirements (#13388)
    ## Why
    
    Enterprises can already constrain approvals, sandboxing, and web search
    through `requirements.toml` and MDM, but feature flags were still only
    configurable as managed defaults. That meant an enterprise could suggest
    feature values, but it could not actually pin them.
    
    This change closes that gap and makes enterprise feature requirements
    behave like the other constrained settings. The effective feature set
    now stays consistent with enterprise requirements during config load,
    when config writes are validated, and when runtime code mutates feature
    flags later in the session.
    
    It also tightens the runtime API for managed features. `ManagedFeatures`
    now follows the same constraint-oriented shape as `Constrained<T>`
    instead of exposing panic-prone mutation helpers, and production code
    can no longer construct it through an unconstrained `From<Features>`
    path.
    
    The PR also hardens the `compact_resume_fork` integration coverage on
    Windows. After the feature-management changes,
    `compact_resume_after_second_compaction_preserves_history` was
    overflowing the libtest/Tokio thread stacks on Windows, so the test now
    uses an explicit larger-stack harness as a pragmatic mitigation. That
    may not be the ideal root-cause fix, and it merits a parallel
    investigation into whether part of the async future chain should be
    boxed to reduce stack pressure instead.
    
    ## What Changed
    
    Enterprises can now pin feature values in `requirements.toml` with the
    requirements-side `features` table:
    
    ```toml
    [features]
    personality = true
    unified_exec = false
    ```
    
    Only canonical feature keys are allowed in the requirements `features`
    table; omitted keys remain unconstrained.
    
    - Added a requirements-side pinned feature map to
    `ConfigRequirementsToml`, threaded it through source-preserving
    requirements merge and normalization in `codex-config`, and made the
    TOML surface use `[features]` (while still accepting legacy
    `[feature_requirements]` for compatibility).
    - Exposed `featureRequirements` from `configRequirements/read`,
    regenerated the JSON/TypeScript schema artifacts, and updated the
    app-server README.
    - Wrapped the effective feature set in `ManagedFeatures`, backed by
    `ConstrainedWithSource<Features>`, and changed its API to mirror
    `Constrained<T>`: `can_set(...)`, `set(...) -> ConstraintResult<()>`,
    and result-returning `enable` / `disable` / `set_enabled` helpers.
    - Removed the legacy-usage and bulk-map passthroughs from
    `ManagedFeatures`; callers that need those behaviors now mutate a plain
    `Features` value and reapply it through `set(...)`, so the constrained
    wrapper remains the enforcement boundary.
    - Removed the production loophole for constructing unconstrained
    `ManagedFeatures`. Non-test code now creates it through the configured
    feature-loading path, and `impl From<Features> for ManagedFeatures` is
    restricted to `#[cfg(test)]`.
    - Rejected legacy feature aliases in enterprise feature requirements,
    and return a load error when a pinned combination cannot survive
    dependency normalization.
    - Validated config writes against enterprise feature requirements before
    persisting changes, including explicit conflicting writes and
    profile-specific feature states that normalize into invalid
    combinations.
    - Updated runtime and TUI feature-toggle paths to use the constrained
    setter API and to persist or apply the effective post-constraint value
    rather than the requested value.
    - Updated the `core_test_support` Bazel target to include the bundled
    core model-catalog fixtures in its runtime data, so helper code that
    resolves `core/models.json` through runfiles works in remote Bazel test
    environments.
    - Renamed the core config test coverage to emphasize that effective
    feature values are normalized at runtime, while conflicting persisted
    config writes are rejected.
    - Ran `compact_resume_after_second_compaction_preserves_history` inside
    an explicit 8 MiB test thread and Tokio runtime worker stack, following
    the existing larger-stack integration-test pattern, to keep the Windows
    `compact_resume_fork` test slice from aborting while a parallel
    investigation continues into whether some of the underlying async
    futures should be boxed.
    
    ## Verification
    
    - `cargo test -p codex-config`
    - `cargo test -p codex-core feature_requirements_ -- --nocapture`
    - `cargo test -p codex-core
    load_requirements_toml_produces_expected_constraints -- --nocapture`
    - `cargo test -p codex-core
    compact_resume_after_second_compaction_preserves_history -- --nocapture`
    - `cargo test -p codex-core compact_resume_fork -- --nocapture`
    - Re-ran the built `codex-core` `tests/all` binary with
    `RUST_MIN_STACK=262144` for
    `compact_resume_after_second_compaction_preserves_history` to confirm
    the explicit-stack harness fixes the deterministic low-stack repro.
    - `cargo test -p codex-core`
    - This still fails locally in unrelated integration areas that expect
    the `codex` / `test_stdio_server` binaries or hit existing `search_tool`
    wiremock mismatches.
    
    ## Docs
    
    `developers.openai.com/codex` should document the requirements-side
    `[features]` table for enterprise and MDM-managed configuration,
    including that it only accepts canonical feature keys and that
    conflicting config writes are rejected.
  • Feat: Preserve network access on read-only sandbox policies (#13409)
    ## Summary
    
    `PermissionProfile.network` could not be preserved when additional or
    compiled permissions resolved to
    `SandboxPolicy::ReadOnly`, because `ReadOnly` had no network_access
    field. This change makes read-only + network
    enabled representable directly and threads that through the protocol,
    app-server v2 mirror, and permission-
      merging logic.
    
    ## What changed
    
    - Added `network_access: bool` to `SandboxPolicy::ReadOnly` in the core
    protocol and app-server v2 protocol.
    - Kept backward compatibility by defaulting the new field to false, so
    legacy read-only payloads still
        deserialize unchanged.
    - Updated `has_full_network_access()` and sandbox summaries to respect
    read-only network access.
      - Preserved PermissionProfile.network when:
          - compiling skill permission profiles into sandbox policies
          - normalizing additional permissions
          - merging additional permissions into existing sandbox policies
    - Updated the approval overlay to show network in the rendered
    permission rule when requested.
      - Regenerated app-server schema fixtures for the new v2 wire shape.
  • feat(app-server): add a skills/changed v2 notification (#13414)
    This adds a first-class app-server v2 `skills/changed` notification for
    the existing skills live-reload signal.
    
    Before this change, clients only had the legacy raw
    `codex/event/skills_update_available` event. With this PR, v2 clients
    can listen for a typed JSON-RPC notification instead of depending on the
    legacy `codex/event/*` stream, which we want to remove soon.
  • Add under-development original-resolution view_image support (#13050)
    ## Summary
    
    Add original-resolution support for `view_image` behind the
    under-development `view_image_original_resolution` feature flag.
    
    When the flag is enabled and the target model is `gpt-5.3-codex` or
    newer, `view_image` now preserves original PNG/JPEG/WebP bytes and sends
    `detail: "original"` to the Responses API instead of using the legacy
    resize/compress path.
    
    ## What changed
    
    - Added `view_image_original_resolution` as an under-development feature
    flag.
    - Added `ImageDetail` to the protocol models and support for serializing
    `detail: "original"` on tool-returned images.
    - Added `PromptImageMode::Original` to `codex-utils-image`.
      - Preserves original PNG/JPEG/WebP bytes.
      - Keeps legacy behavior for the resize path.
    - Updated `view_image` to:
    - use the shared `local_image_content_items_with_label_number(...)`
    helper in both code paths
      - select original-resolution mode only when:
        - the feature flag is enabled, and
        - the model slug parses as `gpt-5.3-codex` or newer
    - Kept local user image attachments on the existing resize path; this
    change is specific to `view_image`.
    - Updated history/image accounting so only `detail: "original"` images
    use the docs-based GPT-5 image cost calculation; legacy images still use
    the old fixed estimate.
    - Added JS REPL guidance, gated on the same feature flag, to prefer JPEG
    at 85% quality unless lossless is required, while still allowing other
    formats when explicitly requested.
    - Updated tests and helper code that construct
    `FunctionCallOutputContentItem::InputImage` to carry the new `detail`
    field.
    
    ## Behavior
    
    ### Feature off
    - `view_image` keeps the existing resize/re-encode behavior.
    - History estimation keeps the existing fixed-cost heuristic.
    
    ### Feature on + `gpt-5.3-codex+`
    - `view_image` sends original-resolution images with `detail:
    "original"`.
    - PNG/JPEG/WebP source bytes are preserved when possible.
    - History estimation uses the GPT-5 docs-based image-cost calculation
    for those `detail: "original"` images.

  • Add thread metadata update endpoint to app server (#13280)
    ## Summary
    - add the v2 `thread/metadata/update` API, including
    protocol/schema/TypeScript exports and app-server docs
    - patch stored thread `gitInfo` in sqlite without resuming the thread,
    with validation plus support for explicit `null` clears
    - repair missing sqlite thread rows from rollout data before patching,
    and make those repairs safe by inserting only when absent and updating
    only git columns so newer metadata is not clobbered
    - keep sqlite authoritative for mutable thread git metadata by
    preserving existing sqlite git fields during reconcile/backfill and only
    using rollout `SessionMeta` git fields to fill gaps
    - add regression coverage for the endpoint, repair paths, concurrent
    sqlite writes, clearing git fields, and rollout/backfill reconciliation
    - fix the login server shutdown race so cancelling before the waiter
    starts still terminates `block_until_done()` correctly

  • chore(app-server): restore EventMsg TS types (#13397)
    Realized EventMsg generated types were unintentionally removed as part
    of this PR: https://github.com/openai/codex/pull/13375
    
    Turns out our TypeScript export pipeline relied on transitively reaching
    `EventMsg`. We should still export `EventMsg` explicitly since we're
    still emitting `codex/event/*` events (for now, but getting dropped soon
    as well).
  • chore(app-server): delete v1 RPC methods and notifications (#13375)
    ## Summary
    This removes the old app-server v1 methods and notifications we no
    longer need, while keeping the small set the main codex app client still
    depends on for now.
    
    The remaining legacy surface is:
    - `initialize`
    - `getConversationSummary`
    - `getAuthStatus`
    - `gitDiffToRemote`
    - `fuzzyFileSearch`
    - `fuzzyFileSearch/sessionStart`
    - `fuzzyFileSearch/sessionUpdate`
    - `fuzzyFileSearch/sessionStop`
    
    And the raw `codex/event/*` notifications emitted from core. These
    notifications will be removed in a followup PR.
    
    ## What changed
    - removed deprecated v1 request variants from the protocol and
    app-server dispatcher
    - removed deprecated typed notifications: `authStatusChange`,
    `loginChatGptComplete`, and `sessionConfigured`
    - updated the app-server test client to use v2 flows instead of deleted
    v1 flows
    - deleted legacy-only app-server test suites and added focused coverage
    for `getConversationSummary`
    - regenerated app-server schema fixtures and updated the MCP interface
    docs to match the remaining compatibility surface
    
    ## Testing
    - `just write-app-server-schema`
    - `cargo test -p codex-app-server-protocol`
