  • 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.
  • 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.
  • path-uri: clarify host-native path conversion (#29501)
    ## Why
    
    Downstream refactors are producing confusing code with this
    functionality having a very generic name. Encoding the specific
    conversion approach in the method name makes it clearer.
    
    ## What
    
    Rename `PathUri::from_path` to `PathUri::from_host_native_path` and
    update its Rust call sites.
  • unified-exec: retain PathUri in command events (#28780)
    ## Why
    
    App-server must report command events containing foreign-platform paths
    without changing existing client or rollout path-string formats.
    
    ## What changed
    
    - retain `PathUri` through exec command begin/end events
    - convert cwd values to `LegacyAppPathString` at the app-server
    compatibility boundary
    - drop command actions with foreign paths and log them
    - serialize rollout-trace cwd values using their inferred native path
    representation
    - restore Wine coverage for retained Windows cwd values and successful
    completion
  • [codex] re-enable absolute workdir integration test (#28581)
    ## Why
    
    In #28146 I missed the invariant that an absolute `exec_command` workdir
    must override the environment cwd. The existing integration test would
    have caught that regression, but it was ignored as flaky.
    
    ## What
    
    Re-enable `unified_exec_respects_workdir_override`.
    
    ## Validation
    
    `just test -p codex-core unified_exec_respects_workdir_override`
  • [codex] Warn clearly when code mode output is truncated (#28467)
    ## Summary
    
    - make `formatted_truncate_text` prepend `Warning: truncated output
    (original token count: N)` above the existing `Total output lines`
    header
    - update direct formatter, unified-exec, user-shell, and code-mode
    expectations
    - add core unit coverage that runs in Bazel without requiring the
    skipped V8-backed code-mode integration suite
    
    ## Validation
    
    - `cargo test -p codex-utils-output-truncation -- --nocapture` (17
    passed)
    - `cargo test -p codex-core --lib
    truncated_text_output_starts_with_warning -- --nocapture`
    - `cargo test -p codex-core --test all
    clamps_model_requested_max_output_tokens_to_policy -- --nocapture` (2
    passed)
    - `cargo test -p codex-core --test all
    unified_exec_formats_large_output_summary -- --nocapture`
    - `cargo test -p codex-core --test all
    user_shell_command_output_is_truncated_in_history -- --nocapture`
    - Bazel CI exercises the shared formatter and downstream integration
    expectations
  • [codex] Use expect in integration tests (#28441)
    The workspace denies `clippy::expect_used` in production. Although
    `clippy.toml` allows `expect` in tests, Bazel Clippy compiles
    integration-test helper code in a way that does not receive that
    exemption, which encouraged verbose `unwrap_or_else(... panic!(...))`
    and equivalent `match`/`let else` forms.
    
    This allows `clippy::expect_used` once at each integration-test crate
    root (including aggregated suites and test-support libraries), then
    replaces manual panic-based Result and Option unwraps with
    `expect`/`expect_err`. Standalone `tests/*.rs` files remain their own
    crate roots. Intentional assertion and unexpected-variant panics remain
    unchanged, and the production `expect_used = "deny"` lint remains in
    place.
    
    The cleanup is mechanical and net-negative in line count.
  • Run core integration tests against a Wine-backed Windows executor (#28401)
    ## Why
    
    We want to exercise a linux app-server against a windows exec-server
    without having to repeat every test case. This approach has slight
    precedent in the remote docker test setup.
    
    ## What
    
    Run the shared `codex-core` integration suite against Windows
    exec-server behavior from Linux. This makes cross-OS path and shell
    regressions visible while keeping unsupported cases owned by individual
    tests.
    
    - Add `local`, `docker`, and `wine-exec` test environment selection with
    legacy Docker compatibility.
    - Extend `codex_rust_crate` to generate a sharded Wine-exec variant
    using a cross-built Windows server and pinned Bazel Wine/PowerShell
    runtimes.
    - Teach remote-aware helpers about Windows paths and track temporary
    incompatibilities with source-local `skip_if_wine_exec!` calls and
    follow-up reasons.
  • feat(core): add metadata field to ResponseItem (#28355)
    ## Description
    
    This PR adds an optional `metadata` field to `ResponseItem` for
    Responses API calls. Only mechanical plumbing, no actual values
    populated and sent yet. Turns out just adding a new field to
    `ResponseItem` has quite a large blast radius already.
    
    This change is backwards compatible because `metadata` is optional and
    omitted when absent, so existing response items and rollout history
    without it still deserialize and requests that do not set it keep the
    same wire shape. For provider compatibility, we strip out `metadata`
    before non-OpenAI Responses requests so Azure and AWS Bedrock never see
    this field.
    
    My followup PR here will actually make use of it to start storing and
    passing along `turn_id`: https://github.com/openai/codex/pull/28360
    
    ## What changed
    
    - Added `ResponseItemMetadata` with optional `turn_id`, plus optional
    `metadata` on Responses API item variants and inter-agent communication.
    - Preserved item metadata through response-item rewrites such as
    truncation, missing tool-output synthesis, compaction history
    rebuilding, visible-history conversion, rollout/resume, and generated
    app-server schemas/types.
    - Strip item metadata from non-OpenAI Responses requests while
    preserving it for OpenAI-shaped requests.
    - Updated the mechanical fixture/test construction churn required by the
    new optional field.
  • [codex] Let generic test turns inherit their environment (#27972)
    ## Why
    
    The paired thread-environment migration changed several generic test
    turn helpers from supplying a fallback cwd to explicitly selecting the
    local environment. That changes their meaning under
    `build_with_remote_env()`: remote-only fixtures cannot resolve the
    forced local selection, so the tests fail before exercising apply-patch,
    RMCP, unified-exec, or view-image behavior.
    
    Generic helpers should inherit the environment selected by their
    fixture. Tests that intentionally exercise local routing continue to
    select the local environment explicitly.
    
    ## What changed
    
    - Remove forced `local_selections(...)` overrides from the generic
    apply-patch, RMCP, unified-exec, and view-image turn helpers.
    - Remove the imports made unused by those deletions.
    
    ## Testing
    
    - Not run locally; this is a test-fixture-only change and the `full-ci`
    branch will exercise the affected remote shards.
  • [codex] migrate ExecutorFileSystem paths to PathUri (#27424)
    ## Why
    
    We're moving exec-server to use PathUri for its internal path
    representations.
    
    ## What
    
    Move `ExecutorFileSystem` APIs to use `PathUri` instead of
    `AbsolutePathBuf`. Future changes will convert higher-level parts of
    exec-server.
  • [codex] Handle Ctrl-C for non-TTY unified exec (#26734)
    ## Why
    
    A long-running unified exec process started with `tty: false` could not
    be interrupted via `write_stdin`: ordinary non-TTY stdin writes are
    rejected once stdin is closed, but an exact U+0003 payload should still
    map to a process interrupt. The interrupt should flow through the same
    process lifecycle path as a real signal so Codex preserves
    process-reported output and exit metadata instead of fabricating a
    Ctrl-C exit code or tearing down the session early.
    
    ## What Changed
    
    - Add `process/signal` to exec-server with `ProcessSignal::Interrupt`
    and an empty response.
    - Add a non-consuming `ProcessHandle::signal` path for spawned
    processes; on Unix it sends SIGINT to the process group and leaves
    terminate/hard-kill unchanged.
    - Route non-TTY U+0003 `write_stdin` through `process.signal(...)`
    instead of `terminate`, then let the normal post-write collection path
    drain output and observe exit.
    - Add exec-server coverage where a shell `trap INT` handler prints the
    signal and exits with its own code.
    - Add unified exec coverage where a `tty: false` process traps SIGINT,
    emits output, and exits with its own code.
    
    ## Validation
    
    - `just test -p codex-exec-server
    exec_process_signal_interrupts_process`
    - `just test -p codex-exec-server`
    - `just test -p codex-core
    write_stdin_ctrl_c_interrupts_non_tty_session`
  • Pair thread environment settings (#26687)
    ## Why
    
    Thread cwd and environment selections are a single logical setting in
    core: updating one without the other can silently desynchronize the
    next-turn execution context. This change makes that relationship
    explicit in the internal thread settings flow while preserving the
    existing app-server public API shape.
    
    ## What changed
    
    - Moved the cwd/environment pair through internal
    `ThreadSettingsOverrides.environment_settings` instead of a top-level
    internal `cwd` field.
    - Kept `thread/settings/update` public params unchanged, with app-server
    translating top-level `cwd` into the paired internal settings shape.
    - Moved `Op::UserInput` environment overrides into thread settings so
    user turns and settings updates use the same core path.
    - Updated core, app-server, MCP, memories, sample, and test callsites to
    construct the paired settings shape.
    
    ## Verification
    
    - `git diff --check`
    - Local test run starting after PR creation.
  • Require absolute cwd in thread settings (#26532)
    ## Why
    
    Thread settings cwd overrides are expected to be resolved before they
    enter core. Keeping this boundary as a plain `PathBuf` made it easy for
    core/session code to keep fallback normalization and relative-path
    resolution logic in places that should only receive an already-resolved
    cwd.
    
    This is intentionally the absolute-cwd-only slice: it does not change
    environment selection stickiness or cwd-to-default-environment fallback
    behavior.
    
    ## What changed
    
    - Changes `ThreadSettingsOverrides.cwd`,
    `CodexThreadSettingsOverrides.cwd`, and `SessionSettingsUpdate.cwd` to
    use `AbsolutePathBuf`.
    - Removes core-side cwd normalization/resolution from session settings
    updates.
    - Updates affected core/app-server test helpers and callsites to pass
    existing absolute cwd values or use `abs()` helpers.
    
    ## Validation
    
    Opening as draft so CI can start while local validation continues.
  • Switch runtime to cloud config bundle (#24622)
    ## Summary
    
    - Adapts the moved `codex-cloud-config` crate from the legacy cloud
    requirements endpoint to the new config bundle endpoint.
    - Switches runtime consumers from `CloudRequirementsLoader` to
    `CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
    config and requirements.
    - Removes the legacy cloud requirements domain loader path.
    
    ## Details
    
    This intentionally keeps `codex-cloud-config` monolithic for review
    lineage: the previous PR establishes the crate move, and this PR shows
    the behavior change against that moved implementation. A follow-up PR
    splits the module back into focused files.
    
    The new bundle path preserves the important cloud requirements loader
    semantics where intended: account-scoped signed cache, 30 minute TTL, 5
    minute refresh cadence, retry/backoff, auth recovery, and fail-closed
    startup loading. The cached payload changes from a single requirements
    TOML string to the backend-delivered bundle, and validation rejects
    malformed config or requirements fragments before cache write/use.
  • Add experimental turn additional context (#24154)
    ## Summary
    
    Adds experimental `additionalContext` support to `turn/start` and
    `turn/steer` so clients can provide ephemeral external context, such as
    browser or automation state, without turning that plumbing into a
    visible user prompt or triggering user-prompt lifecycle behavior.
    
    ## API Shape
    
    The parameter shape is:
    
    ```ts
    additionalContext?: Record<string, {
      value: string
      kind: "untrusted" | "application"
    }> | null
    ```
    
    Example:
    
    ```json
    {
      "additionalContext": {
        "browser_info": {
          "value": "Active tab is CI failures.",
          "kind": "untrusted"
        },
        "automation_info": {
          "value": "CI rerun is in progress.",
          "kind": "application"
        }
      }
    }
    ```
    
    The keys are opaque and caller-defined.
    
    ## Context Injection
    
    When provided, accepted entries are inserted into model context as
    hidden contextual message items, not as visible thread user-message
    items.
    
    `kind: "untrusted"` entries are inserted with role `user`:
    
    ```text
    <external_${key}>${value}</external_${key}>
    ```
    
    `kind: "application"` entries are inserted with role `developer`:
    
    ```text
    <${key}>${value}</${key}>
    ```
    
    Values are not escaped. Each value is truncated to 1k approximate tokens
    before wrapping.
    
    For `turn/start`, accepted additional context is inserted before normal
    user input. For `turn/steer`, additional context is merged only when the
    steer includes non-empty user input; context-only steers still reject as
    empty input.
    
    ## Dedupe Strategy
    
    `AdditionalContextStore` lives on session state and stores the latest
    complete additional-context map.
    
    Each `turn/start` or non-empty `turn/steer` treats its
    `additionalContext` as the current complete set of values. Entries are
    injected only when the key is new or the exact entry for that key
    changed, including `value` or `kind`. After merging, the store is
    replaced with the provided map, so omitted keys are removed from the
    retained set and can be injected again later if reintroduced.
    
    Omitting `additionalContext`, passing `null`, or passing an empty object
    resets the store to empty and injects nothing.
    
    ## What Changed
    
    - Threads experimental v2 `additionalContext` through app-server into
    core turn start and steer handling.
    - Adds separate contextual fragment types for untrusted user-role
    context and application developer-role context.
    - Uses pending response input items so additional context can be
    combined with normal user input without treating it as prompt text.
    - Adds integration coverage for start/steer flow, role routing,
    dedupe/reset behavior, deletion/re-add behavior, hook-blocked input
    behavior, empty context-only steer rejection, external-fragment marker
    matching, and truncation.
  • Fix stale background terminal poll events (#23231)
    ## Why
    
    Issue #23214 reports `/ps` showing no background terminals while the
    status line still says it is waiting for a background terminal. The race
    is in core: `write_stdin` can poll a process that exits before the
    response returns. The process manager correctly returns `process_id:
    None`, but the handler still emitted a `TerminalInteraction` event using
    the requested session id, causing clients to believe a dead process was
    still being polled.
    
    Fixes #23214.
    
    ## What changed
    
    - Suppress `TerminalInteraction` events for empty `write_stdin` polls
    once `response.process_id` is `None`.
    - Continue emitting interactions for non-empty stdin, even if that input
    causes the process to exit before the response returns.
    - Extend the unified exec integration test to assert completed empty
    polls do not emit terminal interactions.
    
    ## Verification
    
    - `cargo test -p codex-core --test all
    unified_exec_emits_one_begin_and_one_end_event`
    - `cargo test -p codex-core --test all
    unified_exec_emits_terminal_interaction_for_write_stdin`
    
    `cargo test -p codex-core` currently aborts in unrelated
    `agent::control::tests::resume_agent_from_rollout_uses_edge_data_when_descendant_metadata_source_is_stale`
    with a reproducible stack overflow.
  • Make deny canonical for filesystem permission entries (#23493)
    ## Why
    Filesystem permission profiles used `none` for deny-read entries, which
    is less direct than the action the entry actually represents. This
    change makes `deny` the canonical filesystem permission spelling while
    preserving compatibility for older configs that still send `none`.
    
    ## What changed
    - rename `FileSystemAccessMode::None` to `Deny`
    - serialize and generate schemas with `deny` as the canonical value
    - retain `none` only as a legacy input alias for temporary config
    compatibility
    - update filesystem glob diagnostics and regression coverage to use the
    canonical spelling
    - refresh config and app-server schema fixtures to match the new wire
    shape
    
    ## Validation
    - `cargo test -p codex-protocol`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core config_toml_deserializes_permission_profiles
    --lib`
    - `cargo test -p codex-core
    read_write_glob_patterns_still_reject_non_subpath_globs --lib`
    
    Earlier in the session, a broad `cargo test -p codex-core` run reached
    unrelated pre-existing failures in timing/snapshot/git-info tests under
    this environment; the targeted surfaces touched by this PR passed
    cleanly.

  • test: reduce core sandbox policy test setup (#23036)
    ## Why
    
    `SandboxPolicy` is a legacy compatibility shape, but several core tests
    still used it for ordinary turn setup even when the runtime path now
    carries `PermissionProfile`. With the first cleanup PR merged, this
    follow-up trims more core test scaffolding so remaining `SandboxPolicy`
    matches are easier to classify as production compatibility,
    legacy-boundary coverage, or explicit conversion tests.
    
    ## What Changed
    
    - Updated apply-patch handler and runtime tests to pass
    `PermissionProfile` directly.
    - Changed sandboxing test helpers to build permission profiles without
    first creating `SandboxPolicy` values.
    - Converted request-permissions integration turns to pass
    `PermissionProfile` through the test helper, leaving legacy sandbox
    projection at the `Op::UserTurn` boundary.
    - Converted unified exec integration helpers and direct turn submissions
    to use `PermissionProfile` values instead of `SandboxPolicy` setup.
    - Removed now-unused `SandboxPolicy` imports from the touched core
    tests.
    
    ## Test Plan
    
    - `just fmt`
    - `cargo test -p codex-core --lib tools::sandboxing::tests`
    - `cargo test -p codex-core --lib tools::runtimes::apply_patch::tests`
    - `cargo test -p codex-core --lib tools::handlers::apply_patch::tests`
    - `cargo test -p codex-core --lib unified_exec::process_manager::tests`
    - `cargo test -p codex-core --test all request_permissions::`
    - `cargo test -p codex-core --test all unified_exec::`
    - `just fix -p codex-core`
  • test: construct permission profiles directly (#23030)
    ## Why
    
    `SandboxPolicy` is now a legacy compatibility shape, but several tests
    still built a `SandboxPolicy` only to immediately convert it into
    `PermissionProfile` for APIs that already accept canonical runtime
    permissions. Those detours make it harder to audit where legacy sandbox
    policy is still required, because boundary-only usages are mixed
    together with ordinary test setup.
    
    ## What Changed
    
    - Updated tests in `codex-core`, `codex-exec`, `codex-analytics`, and
    `codex-config` to construct `PermissionProfile` values directly when the
    code under test takes a permission profile.
    - Changed exec-policy, request-permissions, session, and sandbox test
    helpers to pass `PermissionProfile` through instead of converting from
    `SandboxPolicy` internally.
    - Left `SandboxPolicy` in place where tests are explicitly exercising
    legacy compatibility or request/response boundaries.
    
    ## Test Plan
    
    - `cargo test -p codex-analytics -p codex-config`
    - `cargo test -p codex-core --lib safety::tests`
    - `cargo test -p codex-core --lib exec_policy::tests::`
    - `cargo test -p codex-core --lib exec::tests`
    - `cargo test -p codex-core --lib guardian_review_session_config`
    - `cargo test -p codex-core --lib tools::network_approval::tests`
    - `cargo test -p codex-core --lib
    tools::runtimes::shell::unix_escalation::tests`
    - `cargo test -p codex-core --lib managed_network`
    - `cargo test -p codex-core --test all request_permissions::`
    - `cargo test -p codex-exec sandbox`

  • permissions: support workspace roots in profiles (#22610)
    ## Why
    
    This is the configuration/model half of the alternative permissions
    migration we discussed as a comparison point for
    [#22401](https://github.com/openai/codex/pull/22401) and
    [#22402](https://github.com/openai/codex/pull/22402).
    
    The old `workspace-write` model mixes three concerns that we want to
    keep separate:
    - reusable profile rules that should stay immutable once selected
    - user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
    workspace-write config
    - internal Codex writable roots such as memories, which should not be
    shown as user workspace roots
    
    This PR gives permission profiles first-class `workspace_roots` so users
    can opt multiple repositories into the same `:workspace_roots` rules
    without using broad absolute-path write grants. It also starts
    separating the raw selected profile from the effective runtime profile
    by making `Permissions` expose explicit accessors instead of public
    mutable fields.
    
    A representative `config.toml` looks like this:
    
    ```toml
    default_permissions = "dev"
    
    [permissions.dev.workspace_roots]
    "~/code/openai" = true
    "~/code/developers-website" = true
    
    [permissions.dev.filesystem.":workspace_roots"]
    "." = "write"
    ".codex" = "read"
    ".git" = "read"
    ".vscode" = "read"
    ```
    
    If Codex starts in `~/code/codex` with that profile selected, the
    effective workspace-root set becomes:
    - `~/code/codex` from the runtime `cwd`
    - `~/code/openai` from the profile
    - `~/code/developers-website` from the profile
    
    The `:workspace_roots` rules are materialized across each root, so
    `.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
    Runtime additions such as `--add-dir` can still layer on later stack
    entries without mutating the selected profile.
    
    ## Stack Shape
    
    This PR intentionally stops before the profile-identity cleanup in
    [#22683](https://github.com/openai/codex/pull/22683) so the base review
    stays focused on config loading, workspace-root materialization, and
    compatibility with legacy `workspace-write`.
    
    The representation in this PR is therefore transitional: `Permissions`
    carries enough state to distinguish the raw constrained profile from the
    effective runtime profile, and there are still call sites that must keep
    the active profile identity and constrained profile value in sync. The
    follow-up PR replaces that with a single resolved profile state
    (`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
    profile id, immutable `PermissionProfile`, and profile-declared
    workspace roots together. That follow-up removes APIs such as
    `set_constrained_permission_profile_with_active_profile()` where
    separate arguments could drift out of sync.
    
    Downstream PRs then build on this base to switch app-server turn updates
    to profile ids plus runtime workspace roots and to finish the
    user-visible summary behavior. Reviewers should judge this PR as the
    workspace-roots foundation, not as the final in-memory shape of selected
    permission profiles.
    
    ## Review Guide
    
    Suggested review order:
    
    1. Start with `codex-rs/core/src/config/mod.rs`.
    This is the main shape change in the base slice. `Permissions` now
    stores a private raw `Constrained<PermissionProfile>` plus runtime
    `workspace_roots`. Callers use `permission_profile()` when they need the
    raw constrained value and `effective_permission_profile()` when they
    need a materialized runtime profile. As noted above,
    [#22683](https://github.com/openai/codex/pull/22683) replaces this
    transitional shape with a resolved profile state that keeps identity and
    profile data together.
    
    2. Review `codex-rs/config/src/permissions_toml.rs` and
    `codex-rs/core/src/config/permissions.rs`.
    These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
    relative to the policy cwd, and keep `:workspace_roots` deny-read glob
    patterns symbolic until the actual roots are known.
    
    3. Review `codex-rs/protocol/src/permissions.rs` and
    `codex-rs/protocol/src/models.rs`.
    These add the policy/profile materialization helpers that expand exact
    `:workspace_roots` entries and scoped deny-read globs over every
    workspace root. This is also where `ActivePermissionProfileModification`
    is removed from the core model.
    
    4. Review the legacy bridge in
    `Config::load_from_base_config_with_overrides` and
    `Config::set_legacy_sandbox_policy`.
    This is where legacy `workspace-write` roots become runtime workspace
    roots, while Codex internal writable roots stay internal and do not
    appear as user-facing workspace roots.
    
    5. Then skim downstream call sites.
    The interesting pattern is raw-vs-effective access: state/proxy/bwrap
    paths keep the raw constrained profile, while execution, summaries, and
    user-visible status use the effective profile and workspace-root list.
    
    ## What Changed
    
    - added `[permissions.<id>.workspace_roots]` to the config model and
    schema
    - added runtime `workspace_roots` state to `Config`/`Permissions` and
    `ConfigOverrides`
    - made `Permissions` profile fields private and replaced direct mutation
    with accessors/setters
    - added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
    materializing `:workspace_roots` exact paths and deny-read globs across
    all roots
    - moved legacy additional writable roots into runtime workspace-root
    state instead of active profile modifications
    - removed `ActivePermissionProfileModification` and its app-server
    protocol/schema export
    - updated sandbox/status summary paths so internal writable roots are
    not reported as user workspace roots
    
    ## Verification Strategy
    
    The targeted tests cover the behavior at the layers where regressions
    are most likely:
    - `codex-rs/core/src/config/config_tests.rs` verifies config loading,
    legacy workspace-root seeding, effective profile materialization, and
    memory-root handling.
    - `codex-rs/core/src/config/permissions_tests.rs` verifies profile
    `workspace_roots` parsing and `:workspace_roots` scoped/glob
    compilation.
    - `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
    glob materialization over multiple workspace roots.
    - `codex-rs/tui/src/status/tests.rs` and
    `codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
    user-facing summaries show effective workspace roots and hide internal
    writes.
    
    I also ran `cargo check --tests` locally after the latest stack refresh
    to catch cross-crate API breakage from the private-field/accessor
    changes.

  • chore(features) rm Feature::ApplyPatchFreeform (#22711)
    ## Summary
    Removes the feature since this is effectively on by default in all cases
    where we should use it, or can be configured via models.json.
    
    ## Testing
    - [x] unit tests pass
  • Fix remote environment test fixtures (#22572)
    ## Why
    The Docker remote-env coverage was failing before it reached the
    behavior those tests are meant to exercise. The remote-aware test
    fixture only registered the remote environment, so tests that
    intentionally select both `local` and `remote` could not start a turn.
    After that was fixed, two tests exposed stale fixtures: the approval
    test was auto-approving under workspace-write, and the remote
    `view_image` test was writing invalid PNG bytes.
    
    ## What Changed
    - Added `EnvironmentManager::create_for_tests_with_local(...)` so tests
    can keep the provider default while also selecting `local` explicitly.
    - Updated `build_remote_aware()` to use that test-only manager when a
    remote exec-server URL is present.
    - Changed the remote apply-patch approval helper to use
    `SandboxPolicy::new_read_only_policy()` so the test actually exercises
    approval caching per environment.
    - Replaced the hardcoded remote `view_image` PNG blob with the existing
    `png_bytes(...)` helper so the test uses a valid image fixture.
    
    ## Validation
    Ran these isolated Docker remote-env tests on the devbox with
    `$remote-tests` setup:
    -
    `suite::remote_env::apply_patch_freeform_routes_to_selected_remote_environment`
    -
    `suite::remote_env::apply_patch_approvals_are_remembered_per_environment`
    -
    `suite::remote_env::apply_patch_intercepted_exec_command_routes_to_selected_remote_environment`
    -
    `suite::remote_env::exec_command_routes_to_selected_remote_environment`
    - `suite::view_image::view_image_routes_to_selected_remote_environment`
    
    All five pass.
  • feat: add network proxy feature flag (#20147)
    ## Why
    
    The permissions migration is making
    `permissions.<profile>.network.enabled` the canonical sandbox network
    bit, while proxy startup is a separate concern. Enabling network access
    should not implicitly start the proxy, and users who are still on legacy
    sandbox modes need a separate place to opt into proxy startup and
    provide proxy-specific settings.
    
    This follow-up to #19900 gives the network proxy its own feature surface
    instead of overloading permission-profile network semantics.
    
    ## What changed
    
    - Add an experimental `network_proxy` feature with a configurable
    `[features.network_proxy]` table.
    - Overlay `features.network_proxy` settings onto the configured proxy
    state after permission-profile selection, so the proxy only starts when
    the active `NetworkSandboxPolicy` already allows network access.
    - Preserve `[experimental_network]` startup behavior independently of
    the new feature flag.
    
    ## Behavior and examples
    
    There are now three related knobs:
    
    - `permissions.<profile>.network.enabled` controls whether the active
    permission profile has network access at all.
    - `features.network_proxy` enables proxy restrictions for an
    already-network-enabled profile.
    - Legacy `sandbox_mode` plus `[sandbox_workspace_write].network_access`
    still control whether legacy `workspace-write` has network access at
    all.
    
    The rule is:
    
    - network off + proxy flag on -> network stays off, proxy is a no-op
    - network on + proxy flag off -> unrestricted direct network
    - network on + proxy flag on -> network stays on, with proxy
    restrictions applied
    
    For permission profiles, the feature toggle adds proxy restrictions only
    when network access is already enabled:
    
    ```toml
    default_permissions = "workspace"
    
    [permissions.workspace.filesystem]
    ":minimal" = "read"
    
    [permissions.workspace.network]
    enabled = true
    
    [features]
    network_proxy = true
    ```
    
    If `network.enabled = false`, the same feature flag is a no-op: network
    remains off and the proxy does not start.
    
    For legacy sandbox config, `network_access` remains the master switch:
    
    ```toml
    sandbox_mode = "workspace-write"
    
    [sandbox_workspace_write]
    network_access = true
    
    [features]
    network_proxy = true
    ```
    
    That keeps legacy `workspace-write` network access on, but routes it
    through the proxy policy. If `network_access = false`, the proxy feature
    is a no-op and legacy `workspace-write` remains offline.
    
    The same proxy opt-in can be supplied from the CLI:
    
    ```bash
    codex -c 'features.network_proxy=true'
    ```
    
    Additional proxy settings can be supplied when a table is needed:
    
    ```bash
    codex \
      -c 'features.network_proxy.enabled=true' \
      -c 'features.network_proxy.enable_socks5=false'
    ```
    
    The intended behavior matrix is:
    
    | Config surface | Network setting | `features.network_proxy` | Direct
    sandbox network | Proxy |
    | --- | --- | --- | --- | --- |
    | Permission profile | `network.enabled = false` | off | restricted |
    off |
    | Permission profile | `network.enabled = false` | on | restricted | off
    |
    | Permission profile | `network.enabled = true` | off | enabled | off |
    | Permission profile | `network.enabled = true` | on | enabled | on |
    | Legacy `workspace-write` | `network_access = false` | off | restricted
    | off |
    | Legacy `workspace-write` | `network_access = false` | on | restricted
    | off |
    | Legacy `workspace-write` | `network_access = true` | off | enabled |
    off |
    | Legacy `workspace-write` | `network_access = true` | on | enabled | on
    |
    
    `[experimental_network]` requirements remain separate from the user
    feature toggle and still start the proxy on their own.
    
    Relevant code:
    -
    [`features/src/feature_configs.rs`](https://github.com/openai/codex/blob/43785aff47/codex-rs/features/src/feature_configs.rs#L58-L117)
    defines the feature-specific proxy config.
    -
    [`core/src/config/mod.rs`](https://github.com/openai/codex/blob/43785aff47/codex-rs/core/src/config/mod.rs#L1959-L1964)
    reads the feature table, and [later applies it only when network access
    is already
    enabled](https://github.com/openai/codex/blob/43785aff47/codex-rs/core/src/config/mod.rs#L2448-L2458).
    
    ## Verification
    
    Added focused coverage for:
    - keeping the proxy off when `features.network_proxy` is enabled but
    sandbox network access is disabled
    - the full permission-profile and legacy `workspace-write` matrix above
    - preserving `[experimental_network]` startup without the feature
    - reusing profile-supplied proxy settings when the feature is enabled
    
    Ran:
    - `cargo test -p codex-features`
    - `cargo test -p codex-core network_proxy_feature`
    - `cargo test -p codex-core
    experimental_network_requirements_enable_proxy_without_feature`
  • fix: handle deferred network proxy denials (#19184)
    ## Why
    
    This bug is exposed by Guardian/auto-review approvals. With the managed
    network proxy enabled, a blocked network request can be reported back
    through the network approval service as an approval denial after the
    command has already started. Before this change, the shell and unified
    exec runtimes registered those network approval calls, but did not have
    a way to observe an async proxy denial as a cancellation/failure signal
    for the running process.
    
    The result was confusing: Guardian/auto-review could correctly deny
    network access, but the command path could keep running or unregister
    the approval without surfacing the denial as the command failure.
    
    ## What Changed
    
    - `NetworkApprovalService` now attaches a cancellation token to active
    and deferred network approvals.
    - Proxy-denial outcomes are recorded only for active registrations,
    cancel the owning token, and are consumed when the approval is
    finalized.
    - The shell runtime combines the normal command timeout with the
    network-denial cancellation token.
    - Unified exec stores the deferred network approval object, terminates
    tracked processes when the proxy denial arrives, and returns the denial
    as a process failure while polling or completing the process.
    - Tool orchestration passes the active network approval cancellation
    token into the sandbox attempt and preserves deferred approval errors
    instead of silently unregistering them.
    - App-server `command/exec` now handles the combined
    timeout-or-cancellation expiration variant used by the runtime.
    
    ## Verification
    
    - `cargo test -p codex-core network_approval --lib`
    - `cargo clippy -p codex-app-server --all-targets -- -D warnings`
    - `cargo clippy -p codex-core --all-targets -- -D warnings`

  • permissions: derive compatibility policies from profiles (#19392)
    ## Why
    
    After #19391, `PermissionProfile` and the split filesystem/network
    policies could still be stored in parallel. That creates drift risk: a
    profile can preserve deny globs, external enforcement, or split
    filesystem entries while a cached projection silently loses those
    details. This PR makes the profile the runtime source and derives
    compatibility views from it.
    
    ## What Changed
    
    - Removes stored filesystem/network sandbox projections from
    `Permissions` and `SessionConfiguration`; their accessors now derive
    from the canonical `PermissionProfile`.
    - Derives legacy `SandboxPolicy` snapshots from profiles only where an
    older API still needs that field.
    - Updates MCP connection and elicitation state to track
    `PermissionProfile` instead of `SandboxPolicy` for auto-approval
    decisions.
    - Adds semantic filesystem-policy comparison so cwd changes can preserve
    richer profiles while still recognizing equivalent legacy projections
    independent of entry ordering.
    - Updates config/session tests to assert profile-derived projections
    instead of parallel stored fields.
    
    ## Verification
    
    - `cargo test -p codex-core direct_write_roots`
    - `cargo test -p codex-core runtime_roots_to_legacy_projection`
    - `cargo test -p codex-app-server

  • chore: apply truncation policy to unified_exec (#19247)
    we were not respecting turn's `truncation_policy` to clamp output tokens
    for `unified_exec` and `write_stdin`.
    
    this meant truncation was only being applied by `ContextManager` before
    the output was stored in-memory (so it _was_ being truncated from
    model-visible context), but the full output was persisted to rollout on
    disk.
    
    now we respect that `truncation_policy` and `ContextManager`-level
    truncation remains a backup.
    
    ### Tests
    added tests, tested locally.
  • tui: carry permission profiles on user turns (#18285)
    ## Why
    
    Per-turn permission overrides should use the same canonical profile
    abstraction as session configuration. That lets TUI submissions preserve
    exact configured permissions without round-tripping through legacy
    sandbox fields.
    
    ## What changed
    
    This adds `permission_profile` to user-turn operations, threads it
    through TUI/app-server submission paths, fills the new field in existing
    test fixtures, and adds coverage that composer submission includes the
    configured profile.

  • ci: make Windows Bazel clippy catch core test imports (#18350)
    ## Why
    
    Unused imports in `core/tests/suite/unified_exec.rs` in the Windows
    build were not caught by Bazel CI on
    https://github.com/openai/codex/pull/18096. I spot-checked
    https://github.com/openai/codex/actions/workflows/rust-ci-full.yml?query=branch%3Amain
    and noticed that builds were consistently red. This revealed that our
    Cargo builds _were_ properly catching these issues, identifying a
    Windows-specific coverage hole in the Bazel clippy job.
    
    The Windows Bazel clippy job uses `--skip_incompatible_explicit_targets`
    so it can lint a broad target set without failing immediately on targets
    that are genuinely incompatible with Windows. However, with the default
    Windows host platform, `rust_test` targets such as
    `//codex-rs/core:core-all-test` could be skipped before the clippy
    aspect reached their integration-test modules. As a result, the imports
    in `core/tests/suite/unified_exec.rs` were not being linted by the
    Windows Bazel clippy job at all.
    
    The clippy diagnostic that Windows Bazel should have surfaced was:

    ## What changed
    
    - Run the Windows Bazel clippy job with the MSVC host platform via
    `--windows-msvc-host-platform`, matching the Windows Bazel test job.
    This keeps `--skip_incompatible_explicit_targets` while ensuring Windows
    `rust_test` targets such as `//codex-rs/core:core-all-test` are still
    linted.
    - Remove the unused imports from `core/tests/suite/unified_exec.rs`.
    - Add `--print-failed-action-summary` to
    `.github/scripts/run-bazel-ci.sh` so Bazel action failures can be
    summarized after the build exits.
    
    ## Failure reporting
    
    Once the coverage issue was fixed, an intentionally reintroduced unused
    import made the Windows Bazel clippy job fail as expected. That exposed
    a separate usability problem: because the job keeps `--keep_going`, the
    top-level Bazel output could still end with:
    
    ```text
    ERROR: Build did NOT complete successfully
    FAILED:
    ```
    
    without the underlying rustc/clippy diagnostic being visible in the
    obvious part of the GitHub Actions log.
    
    To keep `--keep_going` while making failures actionable, the wrapper now
    scans the captured Bazel console output for failed actions and prints
    the matching rustc/clippy diagnostic block. When a diagnostic block is
    found, it is emitted both as a GitHub `::error` annotation and as plain
    expanded log output, rather than being hidden in a collapsed group.
    
    ## Verification
    
    To validate the CI path, I intentionally introduced an unused import in
    `core/tests/suite/unified_exec.rs`. The Windows Bazel clippy job failed
    as expected, confirming that the integration-test module is now covered
    by Bazel clippy. The same failure also verified that the wrapper
    surfaces the matching clippy diagnostics directly in the Actions output.
  • feat(sandbox): add glob deny-read platform enforcement (#18096)
    ## Summary
    - adds macOS Seatbelt deny rules for unreadable glob patterns
    - expands unreadable glob matches on Linux and masks them in bwrap,
    including canonical symlink targets
    - keeps Linux glob expansion robust when `rg` is unavailable in minimal
    or Bazel test environments
    - adds sandbox integration coverage that runs `shell` and `exec_command`
    with a `**/*.env = none` policy and verifies the secret contents do not
    reach the model
    
    ## Linux glob expansion
    
    ```text
    Prefer:   rg --files --hidden --no-ignore --glob <pattern> -- <search-root>
    Fallback: internal globset walker when rg is not installed
    Failure:  any other rg failure aborts sandbox construction
    ```
    
    ```
    [permissions.workspace.filesystem]
    glob_scan_max_depth = 2
    
    [permissions.workspace.filesystem.":project_roots"]
    "**/*.env" = "none"
    ```
    
    
    This keeps the common path fast without making sandbox construction
    depend on an ambient `rg` binary. If `rg` is present but fails for
    another reason, the sandbox setup fails closed instead of silently
    omitting deny-read masks.
    
    ## Platform support
    - macOS: subprocess sandbox enforcement is handled by Seatbelt regex
    deny rules
    - Linux: subprocess sandbox enforcement is handled by expanding existing
    glob matches and masking them in bwrap
    - Windows: policy/config/direct-tool glob support is already on `main`
    from #15979; Windows subprocess sandbox paths continue to fail closed
    when unreadable split filesystem carveouts require runtime enforcement,
    rather than silently running unsandboxed
    
    ## Stack
    1. #15979 - merged: cross-platform glob deny-read
    policy/config/direct-tool support for macOS, Linux, and Windows
    2. This PR - macOS/Linux subprocess sandbox enforcement plus Windows
    fail-closed clarification
    3. #17740 - managed deny-read requirements
    
    ## Verification
    - Added integration coverage for `shell` and `exec_command` glob
    deny-read enforcement
    - `cargo check -p codex-sandboxing -p codex-linux-sandbox --tests`

  • [codex] Fix unified exec test build (#17032)
    ## Summary
    - Remove the stale `?` after `AbsolutePathBuf::join` in the unified exec
    integration test helper.
    
    ## Root Cause
    - `AbsolutePathBuf::join` was made infallible, but
    `core/tests/suite/unified_exec.rs` still treated it as a `Result`, which
    broke the Windows test build for the `all` integration test target.

    - Create workspace directories through the executor filesystem for
    remote runs.
    - Install `python3` and `zsh` in the remote test container so restored

  • Code mode on v8 (#15276)
    Moves Code Mode to a new crate with no dependencies on codex. This
    create encodes the code mode semantics that we want for lifetime,
    mounting, tool calling.
    
    The model-facing surface is mostly unchanged. `exec` still runs raw
    JavaScript, `wait` still resumes or terminates a `cell_id`, nested tools
    are still available through `tools.*`, and helpers like `text`, `image`,
    `store`, `load`, `notify`, `yield_control`, and `exit` still exist.
    
    The major change is underneath that surface:
    
    - Old code mode was an external Node runtime.
    - New code mode is an in-process V8 runtime embedded directly in Rust.
    - Old code mode managed cells inside a long-lived Node runner process.
    - New code mode manages cells in Rust, with one V8 runtime thread per
    active `exec`.
    - Old code mode used JSON protocol messages over child stdin/stdout plus
    Node worker-thread messages.
    - New code mode uses Rust channels and direct V8 callbacks/events.
    
    This PR also fixes the two migration regressions that fell out of that
    substrate change:
    
    - `wait { terminate: true }` now waits for the V8 runtime to actually
    stop before reporting termination.
    - synchronous top-level `exit()` now succeeds again instead of surfacing
    as a script error.
    
    ---
    
    - `core/src/tools/code_mode/*` is now mostly an adapter layer for the
    public `exec` / `wait` tools.
    - `code-mode/src/service.rs` owns cell sessions and async control flow
    in Rust.
    - `code-mode/src/runtime/*.rs` owns the embedded V8 isolate and
    JavaScript execution.
    - each `exec` spawns a dedicated runtime thread plus a Rust
    session-control task.
    - helper globals are installed directly into the V8 context instead of
    being injected through a source prelude.
    - helper modules like `tools.js` and `@openai/code_mode` are synthesized
    through V8 module resolution callbacks in Rust.
    
    ---
    
    Also added a benchmark for showing the speed of init and use of a code
    mode env:
    ```

  • Preserve background terminals on interrupt and rename cleanup command to /stop (#14602)
    ### Motivation
    - Interrupting a running turn (Ctrl+C / Esc) currently also terminates
    long‑running background shells, which is surprising for workflows like
    local dev servers or file watchers.
    - The existing cleanup command name was confusing; callers expect an
    explicit command to stop background terminals rather than a UI clear
    action.
    - Make background‑shell termination explicit and surface a clearer
    command name while preserving backward compatibility.
    
    ### Description
    - Renamed the background‑terminal cleanup slash command from `Clean`
    (`/clean`) to `Stop` (`/stop`) and kept `clean` as an alias in the
    command parsing/visibility layer, updated the user descriptions and
    command popup wiring accordingly.
    - Updated the unified‑exec footer text and snapshots to point to `/stop`
    (and trimmed corresponding snapshot output to match the new label).
    - Changed interrupt behavior so `Op::Interrupt` (Ctrl+C / Esc interrupt)
    no longer closes or clears tracked unified exec / background terminal
    processes in the TUI or core cleanup path; background shells are now
    preserved after an interrupt.
    - Updated protocol/docs to clarify that `turn/interrupt` (or
    `Op::Interrupt`) interrupts the active turn but does not terminate
    background terminals, and that `thread/backgroundTerminals/clean` is the
    explicit API to stop those shells.
    - Updated unit/integration tests and insta snapshots in the TUI and core
    unified‑exec suites to reflect the new semantics and command name.
    
    ### Testing
    - Ran formatting with `just fmt` in `codex-rs` (succeeded). 
    - Ran `cargo test -p codex-protocol` (succeeded). 
    - Attempted `cargo test -p codex-tui` but the build could not complete
    in this environment due to a native build dependency that requires
    `libcap` development headers (the `codex-linux-sandbox` vendored build
    step); install `libcap-dev` / make `libcap.pc` available in
    `PKG_CONFIG_PATH` to run the TUI test suite locally.
    - Updated and accepted the affected `insta` snapshots for the TUI
    changes so visual diffs reflect the new `/stop` wording and preserved
    interrupt behavior.

  • Add Smart Approvals guardian review across core, app-server, and TUI (#13860)
    ## Summary
    - add `approvals_reviewer = "user" | "guardian_subagent"` as the runtime
    control for who reviews approval requests
    - route Smart Approvals guardian review through core for command
    execution, file changes, managed-network approvals, MCP approvals, and
    delegated/subagent approval flows
    - expose guardian review in app-server with temporary unstable
    `item/autoApprovalReview/{started,completed}` notifications carrying
    `targetItemId`, `review`, and `action`
    - update the TUI so Smart Approvals can be enabled from `/experimental`,
    aligned with the matching `/approvals` mode, and surfaced clearly while
    reviews are pending or resolved
    
    ## Runtime model
    This PR does not introduce a new `approval_policy`.
    
    Instead:
    - `approval_policy` still controls when approval is needed
    - `approvals_reviewer` controls who reviewable approval requests are
    routed to:
      - `user`
      - `guardian_subagent`
    
    `guardian_subagent` is a carefully prompted reviewer subagent that
    gathers relevant context and applies a risk-based decision framework
    before approving or denying the request.
    
    The `smart_approvals` feature flag is a rollout/UI gate. Core runtime
    behavior keys off `approvals_reviewer`.
    
    When Smart Approvals is enabled from the TUI, it also switches the
    current `/approvals` settings to the matching Smart Approvals mode so
    users immediately see guardian review in the active thread:
    - `approval_policy = on-request`
    - `approvals_reviewer = guardian_subagent`
    - `sandbox_mode = workspace-write`
    
    Users can still change `/approvals` afterward.
    
    Config-load behavior stays intentionally narrow:
    - plain `smart_approvals = true` in `config.toml` remains just the
    rollout/UI gate and does not auto-set `approvals_reviewer`
    - the deprecated `guardian_approval = true` alias migration does
    backfill `approvals_reviewer = "guardian_subagent"` in the same scope
    when that reviewer is not already configured there, so old configs
    preserve their original guardian-enabled behavior
    
    ARC remains a separate safety check. For MCP tool approvals, ARC
    escalations now flow into the configured reviewer instead of always
    bypassing guardian and forcing manual review.
    
    ## Config stability
    The runtime reviewer override is stable, but the config-backed
    app-server protocol shape is still settling.
    
    - `thread/start`, `thread/resume`, and `turn/start` keep stable
    `approvalsReviewer` overrides
    - the config-backed `approvals_reviewer` exposure returned via
    `config/read` (including profile-level config) is now marked
    `[UNSTABLE]` / experimental in the app-server protocol until we are more
    confident in that config surface
    
    ## App-server surface
    This PR intentionally keeps the guardian app-server shape narrow and
    temporary.
    
    It adds generic unstable lifecycle notifications:
    - `item/autoApprovalReview/started`
    - `item/autoApprovalReview/completed`
    
    with payloads of the form:
    - `{ threadId, turnId, targetItemId, review, action? }`
    
    `review` is currently:
    - `{ status, riskScore?, riskLevel?, rationale? }`
    - where `status` is one of `inProgress`, `approved`, `denied`, or
    `aborted`
    
    `action` carries the guardian action summary payload from core when
    available. This lets clients render temporary standalone pending-review
    UI, including parallel reviews, even when the underlying tool item has
    not been emitted yet.
    
    These notifications are explicitly documented as `[UNSTABLE]` and
    expected to change soon.
    
    This PR does **not** persist guardian review state onto `thread/read`
    tool items. The intended follow-up is to attach guardian review state to
    the reviewed tool item lifecycle instead, which would improve
    consistency with manual approvals and allow thread history / reconnect
    flows to replay guardian review state directly.
    
    ## TUI behavior
    - `/experimental` exposes the rollout gate as `Smart Approvals`
    - enabling it in the TUI enables the feature and switches the current
    session to the matching Smart Approvals `/approvals` mode
    - disabling it in the TUI clears the persisted `approvals_reviewer`
    override when appropriate and returns the session to default manual
    review when the effective reviewer changes
    - `/approvals` still exposes the reviewer choice directly
    - the TUI renders:
    - pending guardian review state in the live status footer, including
    parallel review aggregation
      - resolved approval/denial state in history
    
    ## Scope notes
    This PR includes the supporting core/runtime work needed to make Smart
    Approvals usable end-to-end:
    - shell / unified-exec / apply_patch / managed-network / MCP guardian
    review
    - delegated/subagent approval routing into guardian review
    - guardian review risk metadata and action summaries for app-server/TUI
    - config/profile/TUI handling for `smart_approvals`, `guardian_approval`
    alias migration, and `approvals_reviewer`
    - a small internal cleanup of delegated approval forwarding to dedupe
    fallback paths and simplify guardian-vs-parent approval waiting (no
    intended behavior change)
    
    Out of scope for this PR:
    - redesigning the existing manual approval protocol shapes
    - persisting guardian review state onto app-server `ThreadItem`s
    - delegated MCP elicitation auto-review (the current delegated MCP
    guardian shim only covers the legacy `RequestUserInput` path)

  • 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.

    `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.
  • add fast mode toggle (#13212)
    - add a local Fast mode setting in codex-core (similar to how model id
    is currently stored on disk locally)
    - send `service_tier=priority` on requests when Fast is enabled
    - add `/fast` in the TUI and persist it locally
    - feature flag
  • Allow clients not to send summary as an option (#12950)
    Summary is a required parameter on UserTurn. Ideally we'd like the core
    to decide the appropriate summary level.
    
    Make the summary optional and don't send it when not needed.
