  • fix(app-server): fix optional bool annotations (#24099)
    `#[serde(default)]` wasn't sufficient for our generated TS types to
    reflect that clients didn't have to set them. We also need
    `skip_serializing_if = "std::ops::Not::not"`. This is already a rule in
    our agents.md file.
  • [codex] Add rollout-backed thread content search (#23519)
    ## Summary
    - add experimental `thread/search` for local rollout-backed thread
    search using `rg` over JSONL rollouts
    - return search-specific result rows with optional previews instead of
    storing preview data on `StoredThread` or ordinary `Thread` responses
    - keep `thread/list` separate from full-content search and document the
    new app-server surface
    
    ## Testing
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server
    thread_search_returns_content_and_title_matches -- --nocapture`
  • Make goals feature on by default and no longer experimental (#23732)
    ## Why
    
    The `goals` feature is ready to be available without requiring users to
    opt into experimental features. Keeping it behind the beta flag leaves
    persisted thread goals and automatic goal continuation disabled by
    default.
    
    This PR also marks the goal-related app server APIs and events as no
    longer experimental.
    
    ## What changed
    
    - Mark `goals` as `Stage::Stable`.
    - Enable `goals` by default in `codex-rs/features/src/lib.rs`.
  • Add thread/settings/update app-server API (#23502)
    ## Why
    
    App-server clients need a way to update a thread's next-turn settings
    without starting a turn, adding transcript content, or waiting for turn
    lifecycle events. This gives settings UI a direct path for durable
    thread settings while clients observe the eventual effective state
    through a notification.
    
    This is a simplified rework of PR
    https://github.com/openai/codex/pull/22509. In particular, it changes
    the `thread/settings/update` api to return immediately rather than
    waiting and returning the effective (updated) thread settings. This
    makes the new api consistent with `turn/start` and greatly reduces the
    complexity of the implementation relative to the earlier attempt.
    
    ## What Changed
    
    - Adds experimental `thread/settings/update` with partial-update request
    fields and an empty acknowledgment response.
    - Adds experimental `thread/settings/updated`, carrying full effective
    `ThreadSettings` and scoped by `threadId` to subscribed clients for the
    affected thread.
    - Shares durable settings validation with `turn/start`, including
    `sandboxPolicy` plus `permissions` rejection and `serviceTier: null`
    clearing.
    - Emits the same settings notification when `turn/start` overrides
    change the stored effective thread settings.
    - Regenerates app-server protocol schema fixtures and updates
    `app-server/README.md`.
  • feat: add permission profile list api (#23412)
    ## Why
    
    Clients need a typed permission-profile catalog instead of
    reconstructing that state from config internals.
    
    ## What changed
    
    - Added `permissionProfile/list` to the app-server v2 protocol with
    cursor pagination and optional `cwd`.
    - The list response includes built-in permission profiles plus
    config-defined `[permissions.<id>]` profiles from the effective config
    for the request context.
    - Permission profiles keep optional `description` metadata for display
    purposes.
    - App-server docs and schema fixtures are updated for the new RPC.
  • app-server: use profile ids in v2 permission params (#23360)
    ## Why
    
    The v2 app-server permission profile fields are experimental, but the
    previous migration kept a legacy object payload for profile selection.
    That made clients aware of server-owned `activePermissionProfile`
    metadata such as `extends`, and it kept a
    `legacy_additional_writable_roots` path even though
    `runtimeWorkspaceRoots` now owns runtime workspace-root selection.
    
    This PR makes the client contract match the intended model: clients
    select a permission profile by id, and the server resolves and reports
    active profile provenance in response payloads.
    
    Follow-up to #22611.
    
    ## What Changed
    
    - Changed `thread/start`, `thread/resume`, `thread/fork`, and
    `turn/start` permission profile selection to plain profile id strings.
    - Changed `command/exec.permissionProfile` to a plain profile id string
    for the same client/server ownership split.
    - Removed `PermissionProfileSelectionParams` and the legacy `{ type:
    "profile", modifications: [...] }` compatibility deserializer.
    - Updated app-server, TUI, and `codex exec` call sites to send only ids,
    while keeping `activePermissionProfile` as server response metadata.
    - Updated app-server docs and schema fixtures for the revised
    `command/exec.permissionProfile` shape.
    
    ## Verification
    
    - `cargo test -p codex-app-server-protocol`
    - `RUST_MIN_STACK=8388608 cargo test -p codex-app-server`
    - `cargo test -p codex-exec`

  • feat(app-server): add optional thread_id to experimentalFeature/list (#23335)
    ## Why
    
    `experimentalFeature/list` reports effective feature enablement, but
    currently does not resolve it against a working directory where
    project-local config.toml files can exist and toggle on/off features
    when merged into the effective config after resolving the various config
    layers. That means we effectively (and incorrectly) ignore features set
    in project-local config.
    
    To address that, this PR exposes an optional `thread_id` param which
    allows us to load the thread's `cwd.
    
    ## Testing
    
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server experimental_feature_list`
  • [codex] Add installed-plugin mention API (#22448)
    ## Summary
    - add app-server `plugin/installed` for mention-oriented plugin loading
    - return installed plugins plus explicitly requested install-suggestion
    rows
    - keep remote handling on installed-state data instead of the broad
    catalog listing path
    
    ## Why
    The `@` mention surface only needs plugins that are usable now, plus a
    small product-approved set of install suggestions. It does not need the
    full catalog-shaped `plugin/list` payload that the Plugins page uses.
    
    ## Validation
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core-plugins`
    - `cargo test -p codex-app-server --test all plugin_installed_`
    
    ## Notes
    - The package-wide `cargo test -p codex-app-server` run still hits an
    existing unrelated stack overflow in
    `in_process::tests::in_process_start_clamps_zero_channel_capacity`.

  • app-server-protocol: remove PermissionProfile from API (#22924)
    ## Why
    
    The app server API should expose permission profile identity, not the
    lower-level runtime permission model. `PermissionProfile` is the
    compiled sandbox/network representation that the server uses internally;
    exposing it through app-server-protocol forces clients to understand
    details that should remain implementation-level.
    
    The API boundary should prefer `ActivePermissionProfile`: a stable
    profile id, plus future parent-profile metadata, that clients can pass
    back when they want to select the same active permissions. This also
    avoids schema generation collisions between the app-server v2 API type
    space and the core protocol model.
    
    Incidentally, while PR makes a number of changes to `command/exec`, note
    that we are hoping to deprecate this API in favor of `process/spawn`, so
    we don't need to be too finicky about these changes.
    
    ## What Changed
    
    - Removed `PermissionProfile` from the app-server-protocol API surface,
    including generated schema and TypeScript exports.
    - Changed `CommandExecParams.permissionProfile` to
    `ActivePermissionProfile`.
    - Resolve command exec profile ids through `ConfigManager` for the
    command cwd, matching turn override selection semantics.
    - Updated downstream TUI tests/helpers to use core permission types
    directly instead of app-server-protocol `PermissionProfile` shims.
  • feat(app-server): update remote control APIs for better UX (#22877)
    ## Why
    To help improve `codex remote-control` CLI UX which I plan to do in a
    followup, this PR adds `server-name` to the various remote control APIs:
    - `remoteControl/enable`
    - `remoteControl/disable`
    - `remoteControl/status/changed`
    
    Also, add a `remoteControl/status/read` API. This will be helpful in the
    Codex App.
  • app-server: stop returning thread permission profiles (#22792)
    ## Why
    
    The app-server thread lifecycle API should no longer expose the full
    `PermissionProfile` value. After the permissions-profile migration,
    clients should round-trip only the active profile identity through
    `activePermissionProfile` and `permissions` when that identity is known.
    
    The full profile is server-side config. Treating a response-derived
    legacy sandbox projection as a new local profile can lose named-profile
    restrictions and accidentally widen permissions on the next turn. The
    legacy `sandbox` response field remains only as the
    compatibility/display fallback.
    
    ## What Changed
    
    - Removed `permissionProfile` from `ThreadStartResponse`,
    `ThreadResumeResponse`, and `ThreadForkResponse`.
    - Stopped populating that field in app-server thread start/resume/fork
    responses.
    - Updated embedded exec/TUI response mapping to derive display
    permission state from local config or the legacy sandbox fallback
    instead of a response profile value.
    - Added a TUI turn override shape that distinguishes preserving server
    permissions, selecting an active profile id, and sending a legacy
    sandbox for an explicit local override.
    - Preserved remote app-server permissions across turns by sending
    `permissions` only when an `activePermissionProfile` id is known, and
    otherwise sending no sandbox override unless the user selected a local
    override.
    - Kept embedded `thread/resume` hydration server-authored when
    `activePermissionProfile` is absent, which matches the live-thread
    attach path where the server ignores requested overrides.
    - Updated the app-server README to remove the obsolete lifecycle
    response `permissionProfile` reference. The remaining
    `permissionProfile` README references are request-side permission
    overrides.
    - Regenerated app-server JSON schema and TypeScript fixtures.
    - Kept the generated typed response enum exempt from
    `large_enum_variant`, matching the existing payload enum exemption after
    the lifecycle response variants shrank.
    
    ## How To Review
    
    Start with `codex-rs/app-server-protocol/src/protocol/v2/thread.rs` to
    confirm the response shape, then check the response construction in
    `codex-rs/app-server/src/request_processors`. The generated schema and
    TypeScript fixture changes are mechanical follow-through from the
    protocol removal.
    
    The TUI behavior is the delicate part: review
    `codex-rs/tui/src/app_server_session.rs` for response hydration and
    turn-start override projection, then
    `codex-rs/tui/src/app/thread_routing.rs` for the decision about whether
    the next turn should preserve the server snapshot, send an active
    profile id, or send a legacy sandbox for an explicit local override.

  • app-server: use permission ids and runtime workspace roots (#22611)
    ## Why
    
    This PR builds on [#22610](https://github.com/openai/codex/pull/22610)
    and is the app-server side of the migration from mutable per-turn
    `SandboxPolicy` replacement toward selecting immutable permission
    profiles by id plus mutable runtime workspace roots.
    
    Once permission profiles can carry their own immutable
    `workspace_roots`, app-server no longer needs to mutate the selected
    `PermissionProfile` just to represent thread-specific filesystem
    context. The mutable part now lives on the thread as explicit
    `runtimeWorkspaceRoots`, while `:workspace_roots` remains symbolic until
    the sandbox is realized for a turn.
    
    ## What Changed
    
    - Replaced the v2 permission-selection wrapper surface with plain
    profile ids for `thread/start`, `thread/resume`, `thread/fork`, and
    `turn/start`.
    - Removed the API surface for profile modifications
    (`PermissionProfileSelectionParams`,
    `PermissionProfileModificationParams`,
    `ActivePermissionProfileModification`).
    - Added experimental `runtimeWorkspaceRoots` fields to the thread
    lifecycle and turn-start APIs.
    - Threaded runtime workspace roots through core session/thread
    snapshots, turn overrides, app-server request handling, and command
    execution permission resolution.
    - Kept session permission state symbolic so later runtime root updates
    and cwd-only implicit-root retargeting rebind `:workspace_roots`
    correctly.
    - Updated the embedded clients just enough to send and restore the new
    thread state.
    - Refreshed the generated schema/TypeScript artifacts and the app-server
    README to match the new contract.
    
    ## Verification
    
    Targeted coverage for this layer lives in:
    
    - `codex-rs/app-server-protocol/src/protocol/v2/tests.rs`
    - `codex-rs/app-server/tests/suite/v2/thread_start.rs`
    - `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
    - `codex-rs/app-server/tests/suite/v2/turn_start.rs`
    - `codex-rs/core/src/session/tests.rs`
    
    The key regression checks exercise that:
    
    - `runtimeWorkspaceRoots` resolve against the effective cwd on thread
    start.
    - Profile-declared workspace roots are excluded from the runtime
    workspace roots returned by app-server.
    - A turn-level runtime workspace-root update persists onto the thread
    and is returned by `thread/resume`.
    - A named permission profile selected on one turn remains symbolic so a
    later runtime-root-only turn update changes the actual sandbox writes.
    - A cwd-only turn update retargets the implicit runtime cwd root while
    preserving additional runtime roots.
    - The protocol fixtures and generated client artifacts stay in sync with
    the string-based permission selection contract.

  • Unqueue plugin list and read requests (#22703)
    ## Summary
    - remove the app-server `plugin-read` serialization queue from
    `plugin/list` and `plugin/read`
    - allow plugin read/list requests to start immediately instead of
    waiting behind other plugin read/list requests
    
    ## Test plan
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
  • enable/disable remote control at runtime, not via features (#22578)
    ## Why
    reapplies https://github.com/openai/codex/pull/22386 which was
    previously reverted
    
    Also, introduce `remoteControl/enable` and `remoteControl/disable`
    app-server APIs to toggle on/off remote control at runtime for a given
    running app-server instance.
    
    ## What Changed
    
    - Adds experimental v2 RPCs:
      - `remoteControl/enable`
      - `remoteControl/disable`
    - Adds `RemoteControlRequestProcessor` and routes the new RPCs through
    it instead of `ConfigRequestProcessor`.
    - Adds named `RemoteControlHandle::enable`, `disable`, and `status`
    methods.
    - Makes `remoteControl/enable` return an error when sqlite state DB is
    unavailable, while keeping enrollment/websocket failures as async status
    updates.
    - Adds `AppServerRuntimeOptions.remote_control_enabled` and hidden
    `--remote-control` flags for `codex app-server` and `codex-app-server`.
    - Updates managed daemon startup to use `codex app-server
    --remote-control --listen unix://`.
    - Marks `Feature::RemoteControl` as removed and ignores
    `[features].remote_control`.
    - Updates app-server README entries for the new remote-control methods.
  • [codex] isolate plugin/list from config serialization queue (#22437)
    ## Summary
    - move `plugin/list` from the shared `config` read queue onto a
    dedicated `plugin-list` shared-read queue
    - move `plugin/read` onto that same dedicated shared-read queue as well
    - keep the existing scheduler behavior unchanged
    - allow plugin list/read operations to proceed independently of
    config-family writes, accepting temporary stale or transient read errors
    during concurrent mutations
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`

  • [codex] support executor registry remote environments (#21323)
    ## Summary
    
    Support registry-backed remote executors end to end so downstream
    services can resolve an executor id into an exec-server URL and make
    that environment available to Codex without relying on the legacy cloud
    environments flow.
    
    ## What changed
    
    - switch remote executor registration to the executor registry bootstrap
    contract
    - allow named remote environments to be inserted into
    `EnvironmentManager` at runtime
    - add the experimental app-server RPC `environment/add` so initialized
    experimental clients can register those remote environments for later
    `thread/start` and `turn/start` selection
    
    ## Validation
    
    Ran focused validation locally:
    - `cargo test -p codex-exec-server environment_manager_`
    - `cargo test -p codex-exec-server
    register_executor_posts_with_bearer_token_header`

  • [codex] request desktop attestation from app (#20619)
    ## Summary
    
    TL;DR: teaches `codex-rs` / app-server to request a desktop-provided
    attestation token and attach it as `x-oai-attestation` on the scoped
    ChatGPT Codex request paths.
    
    ![DeviceCheck attestation
    interface](https://raw.githubusercontent.com/openai/codex/dev/jm/devicecheck-diagram-assets/pr-assets/devicecheck-attestation-interface.png)
    
    ## Details
    
    This PR teaches the Codex app-server runtime how to request and attach
    an attestation token. It does not generate DeviceCheck tokens directly;
    instead, it relies on the connected desktop app to advertise that it can
    generate attestation and then asks that app for a fresh header value
    when needed.
    
    The flow is:
    
    1. The Codex desktop app connects to app-server.
    2. During `initialize`, the app can advertise that it supports
    `requestAttestation`.
    3. Before app-server calls selected ChatGPT Codex endpoints, it sends
    the internal server request `attestation/generate` to the app.
    4. app-server receives a pre-encoded header value back.
    5. app-server forwards that value as `x-oai-attestation` on the scoped
    outbound requests.
    
    The code in this repo is mostly protocol and runtime plumbing: it adds
    the app-server request/response shape, introduces an attestation
    provider in core, wires that provider into Responses / compaction /
    realtime setup paths, and covers the intended scoping with tests. The
    signed macOS DeviceCheck generation remains owned by the desktop app PR.

    <summary>E2E DeviceCheck validation</summary>
    
    First validated the signed desktop app boundary directly: launched a
    packaged signed `Codex.app`, sent `attestation/generate`, decoded the
    returned `v1.` attestation header, and validated the extracted
    DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using
    bundle ID `com.openai.codex`. Apple returned `status_code: 200` and
    `is_ok: true`.
    
    Then ran the fuller app + app-server flow. The packaged `Codex.app`
    launched a current-branch app-server via `CODEX_CLI_PATH`, and a local
    MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server
    requested `attestation/generate` from the real Electron app process, and
    the intercepted `/backend-api/codex/responses` traffic included
    `x-oai-attestation` on both routes:
    
    ```text
    GET  /backend-api/codex/responses  Upgrade: websocket  x-oai-attestation: present
    POST /backend-api/codex/responses  Upgrade: none       x-oai-attestation: present
    ```
    
    The captured header decoded to a DeviceCheck token that also validated
    with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`,
    team `2DC432GLL2`).

  • Remove skills list extra roots (#21485)
    ## Summary
    - Remove `perCwdExtraUserRoots` / `SkillsListExtraRootsForCwd` from the
    `skills/list` app-server API.
    - Drop Rust app-server and `codex-core-skills` extra-root plumbing so
    skill scans are keyed by the normal cwd/user/plugin roots only.
    - Regenerate app-server schemas and update docs/tests that only existed
    for the removed extra-roots behavior.
    
    ## Validation
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core-skills`

    - `just fix -p codex-core-skills`
    - `just fix -p codex-app-server`
    - `just fix -p codex-tui`
    
    ## Notes
    - `cargo test -p codex-app-server --test all skills_list` ran the edited
    skills-list cases, but the full filtered run ended on existing
    `skills_changed_notification_is_emitted_after_skill_change` timeout
    after a websocket `401`.
    - `cargo test -p codex-tui --lib` compiled the changed TUI callers, then
    failed two unrelated status permission tests because local
    `/etc/codex/requirements.toml` forbids `DangerFullAccess`.
    - Source-truth check found the OpenAI monorepo still has
    generated/app-server-kit mirror references to the removed field; those
    should be cleaned up when generated app-server types are synced or in a
    companion OpenAI cleanup.

    We want terminal tool review analytics, but the reducer should not stamp
    review timing from its own wall clock.
    
    This PR plumbs review timing through the real protocol and app-server
    seams so downstream analytics can consume the emitter's timestamps
    directly. Guardian reviews keep their enriched `started_at` /
    `completed_at` analytics fields by deriving those legacy second-based
    values from the same protocol-native millisecond lifecycle timestamps,
    rather than sampling a separate analytics clock.
    
    ## What changed
    
    - add `started_at_ms` to user approval request payloads
    - add `started_at_ms` / `completed_at_ms` to guardian review
    notifications
    - preserve Guardian review `started_at` / `completed_at` enrichment from
    the protocol-native timing source
    - stamp typed `ServerResponse` analytics facts with app-server-observed
    `completed_at_ms`
    - thread the new timing fields through core, protocol, app-server, TUI,
    and analytics fixtures

  • feat(app-server, threadstore): Thread pagination APIs and ThreadStore contract (#21566)
    ## Why
    The goal of this PR is to align on app-server and `ThreadStore` API
    updates for paginating through large threads.
    
    
    #### app-server
    ##### `thread/turns/list`
    - Updates `thread/turns/list` to support `itemsView?: "notLoaded" |
    "summary" | "full" | null`, defaulting to `summary`.
    - Implements the current `thread/turns/list` behavior over the existing
    persisted rollout-history fallback:
      - `notLoaded` returns turn envelopes with empty `items`.
    - `summary` returns the first user message and final assistant message
    when available.
      - `full` preserves the existing full item behavior.
    
    Note that this method still uses the naive approach of loading the
    entire rollout file, and returns just the filtered slice of the data.
    Real pagination will come later by leveraging SQLite.
    
    ##### `thread/turns/items/list`
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    
    #### ThreadStore
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    - Adds `ThreadStore` contract types and stubbed methods for listing
    thread turns and listing items within a turn.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    
    This also sketches the storage abstraction we expect to need once turns
    are indexed/stored. In particular, `notLoaded` is useful only if
    ThreadStore can eventually list turn metadata without loading every
    persisted item for each turn.
    
    ## Validation
    
    - Added/updated protocol serialization coverage for the new request and
    response shapes.
    - Added app-server integration coverage for `thread/turns/list` default
    summary behavior and all three `itemsView` modes.
    - Added app-server integration coverage that `thread/turns/items/list`
    returns the expected unsupported JSON-RPC error when experimental APIs
    are enabled.
    - Added thread-store coverage that the default trait methods return
    `ThreadStoreError::Unsupported`.
    
    No developers.openai.com documentation update is needed for this
    internal experimental app-server API surface.
  • Revert state DB injection and agent graph store (#21481)
    ## Why
    
    Reverts #20689 to restore the previous optional state DB plumbing. The
    conflict resolution keeps the newer installation ID and session/thread
    identity changes that landed after #20689, while removing the mandatory
    state DB and agent graph store dependency from ThreadManager
    construction.
    
    ## What changed
    
    - Restored `Option<StateDbHandle>` through app-server, MCP server,
    prompt debug, and test entry points.
    - Removed the `codex-core` dependency on `codex-agent-graph-store` and
    reverted descendant lookup back to the existing state DB path when
    available.
    - Kept newer `installation_id` forwarding by passing it beside the
    optional DB handle.
    - Kept local thread-name updates working when the optional state DB
    handle is absent.
    
    ## Validation
    
    - `git diff --check`
    - `cargo test -p codex-thread-store`
    - `cargo test -p codex-state -p codex-rollout -p
    codex-app-server-protocol`
    - Attempted `env CARGO_INCREMENTAL=0 cargo test -p codex-core -p

  • [codex] allow shared config reads in app-server queue (#21340)
    ## Summary
    - add a shared-read serialization mode for global app-server request
    families
    - let consecutive leading shared reads for the same family run together
    while keeping exclusive requests ordered
    - mark only `skills/list`, `config/read` and `plugin/list` as shared
    reads for now
    
    ## Why
    `skills/list` and `plugin/list` are read-only config-family requests,
    but the app-server queue currently treats every config request as
    exclusive. That means one long `skills/list` can make a later
    `plugin/list` wait even though the two requests do not mutate config.
    
    This change keeps the existing queue order but lets adjacent reads
    overlap. If a write is already waiting, later reads still stay behind
    it, so writes do not starve.
    
    ## Scope
    This intentionally keeps the first pass narrow:
    - shared reads: `skills/list`, `plugin/list`
    - still exclusive: `plugin/install`, `marketplace/*`,
    `skills/config/write`, `config/*write`, `config/read`, and the rest of
    the config family
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server`
    - `just fix -p codex-app-server-protocol`
    - `just fix -p codex-app-server`
    
    ## Desktop verification
    I ran the dev desktop app against this branch's built binary with the
    existing UI timing logs enabled. The app did use
    `/Users/xli/code/codex_6/codex-rs/target/debug/codex`.
    
    The new scheduler behavior works, but this narrow change does not remove
    every cold-start delay: in the observed trace, an earlier exclusive
    `config/read` was already queued ahead of the later `skills/list` and
    `plugin/list` requests, so the page-open plugin requests still waited
    behind that earlier exclusive config-family request before they could
    run together.
    
    That means this PR is the scheduler primitive needed for shared reads,
    not the complete end-to-end latency fix by itself.
    
    ## Not run
    - full workspace test suite, because repo policy requires explicit
    approval before running it after touching `app-server-protocol`
  • feat(app-server): move v2 sessionId onto Thread (#21336)
    ## Why
    
    `session_id` and `thread_id` are separate identities after #20437, but
    app-server only surfaced `sessionId` on the `thread/start`,
    `thread/resume`, and `thread/fork` response envelopes. Other
    thread-bearing surfaces such as `thread/list`, `thread/read`,
    `thread/started`, `thread/rollback`, `thread/metadata/update`, and
    `thread/unarchive` either lacked the grouping key or forced clients to
    special-case those three responses.
    
    Making `sessionId` part of the reusable `Thread` payload gives every v2
    API surface one place to expose session-tree identity.
    
    ## Mental model
      1. thread.sessionId lives on `Thread`
    2. It is a view/runtime identity for the current live session tree, not
    durable stored lineage metadata
    3. When app-server has a live loaded thread, it copies the real value
    from core’s session_configured.session_id
    4. When it only has stored/unloaded data, it falls back to
    thread.sessionId = thread.id
    
    ## What changed
    
    - Added `sessionId` to the v2
    [`Thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server-protocol/src/protocol/v2/thread_data.rs#L105-L109).
    - Removed the duplicate top-level `sessionId` fields from
    `thread/start`, `thread/resume`, and `thread/fork`; clients should now
    read `response.thread.sessionId`.
    - Populated `thread.sessionId` when building live thread responses,
    replaying loaded threads, and returning stored-thread summaries so the
    field is present across start, resume, fork, list, read, rollback,
    metadata-update, unarchive, and `thread/started` paths. See
    [`load_thread_from_resume_source_or_send_internal`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L2824-L2918)
    and
    [`thread_from_stored_thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L3671-L3719).
    - Preserved the stored-thread fallback: if a thread has not been loaded
    into a live session tree yet, `thread.sessionId` falls back to
    `thread.id`; once the thread is live again, the field reports the active
    session tree root.
    - Regenerated the JSON/TypeScript schemas and updated the app-server
    README examples to show
    [`thread.sessionId`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/README.md#L306-L310)
    on the thread object.
  • feat: add session_id (#20437)
    ## Summary
    
    Related to
    https://openai.slack.com/archives/C095U48JNL9/p1777537279707449
    TLDR:
    We update the meaning of session ids and thread ids:
    * thread_id stays as now
    * session_id become a shared id between every thread under a /root
    thread (i.e. every sub-agent share the same session id)
    
    This PR introduces an explicit `SessionId` and threads it through the
    protocol/client boundary so `session_id` and `thread_id` can diverge
    when they need to, while preserving compatibility for older serialized
    `session_configured` events.

  • feat: Add plugin share access controls (#21124)
    Extends `plugin/share/save` to accept optional discoverability and

    `plugin/share/updateTargets` for share-only target updates without
    re-uploading.
  • [codex-analytics] rework thread_source for thread analytics (#20949)
    ## Summary
    - make `thread_source` an explicit optional thread-level field on
    `thread/start`, `thread/fork`, and returned thread payloads
    - persist `thread_source` in rollout/session metadata so resumed live
    threads retain the original value
    - replace the old best-effort `session_source` -> `thread_source`
    mapping with an explicit caller-supplied analytics classification
    
    ## Why
    Before this change, analytics `thread_source` was populated by a
    best-effort mapping from `session_source`. `session_source` describes
    the runtime/client surface, not the actual thread-level origin, so that
    projection was not accurate enough to distinguish cases such as `user`,
    `subagent`, `memory_consolidation`, and future thread origins reliably.
    
    Making `thread_source` explicit keeps one thread-level analytics field
    while letting callers provide the real classification directly instead
    of recovering it indirectly from `session_source`.
    
    ## Impact
    For new analytics events, `thread_source` now reflects the explicit
    thread-level classification supplied by the caller rather than an
    inferred value derived from `session_source`. Existing protocol fields
    remain optional; callers that omit `threadSource` now produce `null`
    instead of a best-effort inferred value.

  • Add Windows sandbox readiness RPC (#20708)
    ## Why
    
    The desktop app on Windows needs a read-only way to tell, before the
    next tool call, whether the local Windows sandbox setup is in a state
    that should block the user and ask for setup again.
    
    The main case we want to cover is the elevated sandbox setup version
    bump. Today, if the app is configured for elevated Windows sandboxing
    and the installed setup is stale, the next sandboxed shell/exec path can
    end up triggering the elevated setup flow directly. That means the user
    can see an unexpected UAC prompt with no UI explanation.
    
    This change adds a small app-server preflight so the desktop app can ask
    “is Windows sandbox ready, not configured, or update-required?” during
    startup and show the appropriate blocking UI before the user hits a tool
    call.
    
    ## What changed
    
    - Added a new read-only app-server RPC: `windowsSandbox/readiness`
    - Added a new protocol enum and response type:
      - `WindowsSandboxReadiness`
      - `WindowsSandboxReadinessResponse`
    - Added core readiness logic in `core/src/windows_sandbox.rs`:
      - `ready`
      - `notConfigured`
      - `updateRequired`
    - Wired the new request through `codex_message_processor`
    - Regenerated the vendored app-server schema fixtures
    
    ## Readiness semantics
    
    This is intentionally a coarse startup/version-bump readiness check, not
    a full predictor of every runtime repair case.
    
    For now, readiness is determined from:
    - the configured Windows sandbox level
    - `sandbox_setup_is_complete()` for elevated mode
    
    That means:
    - `disabled` maps to `notConfigured`
    - `restricted token` maps to `ready`
    - `elevated` maps to `ready` or `updateRequired` depending on
    `sandbox_setup_is_complete()`
    
    This is deliberate for the first UI integration because the common case
    we want to catch is “the app updated, the elevated setup version bumped,
    and the user should see an update-required blocker instead of a surprise
    UAC prompt”.
    
    It does not attempt to model every case where the deeper runtime path
    might decide to repair or re-run setup.
    
    ## Testing
    
    - Ran `cargo fmt --all -- app-server-protocol/src/protocol/common.rs
    app-server-protocol/src/protocol/v2.rs
    app-server/src/codex_message_processor.rs core/src/windows_sandbox.rs
    core/src/windows_sandbox_tests.rs`
    - Added unit tests for the pure readiness mapping in
    `core/src/windows_sandbox_tests.rs`
    - Regenerated vendored schema fixtures with `cargo run -p
    codex-app-server-protocol --bin write_schema_fixtures -- --schema-root
    app-server-protocol/schema`
    - Did not run the full cargo test suite
  • [codex] Add unsandboxed process exec API (#19040)
    ## Why
    
    App-server clients sometimes need argv-based local process execution
    while sandbox policy is controlled outside Codex. Those environments can
    reject sandbox-disabling paths before a command ever starts, even when
    the caller intentionally wants unsandboxed execution.
    
    This PR adds a distinct `process/*` API for that use case instead of
    extending `command/exec` with another sandbox-disabling shape. Keeping
    the new surface separate also makes the future removal of `command/exec`
    simpler: clients that need explicit process lifecycle control can move
    to the newer handle-based API without depending on `command/exec`
    business logic.
    
    ## What changed
    
    - Added v2 process lifecycle methods: `process/spawn`,
    `process/writeStdin`, `process/resizePty`, and `process/kill`.
    - Added process notifications: `process/outputDelta` for streamed
    stdout/stderr chunks and `process/exited` for final exit status and
    buffered output.
    - Made `process/spawn` intentionally unsandboxed and omitted
    sandbox-selection fields such as `sandboxPolicy` and
    `permissionProfile`.
    - Added client-supplied, connection-scoped `processHandle` values for
    follow-up control requests and notification routing.
    - Supported cwd, environment overrides, PTY mode and size, stdin
    streaming, stdout/stderr streaming, per-stream output caps, and timeout
    controls.
    - Killed active process sessions when the originating app-server
    connection closes.
    - Wired the implementation through the modular `request_processors/`
    app-server layout, with process-handle request serialization for
    follow-up control calls.
    - Updated generated JSON/TypeScript schema fixtures and documented the
    new API in `codex-rs/app-server/README.md`.
    - Added v2 app-server integration coverage in
    `codex-rs/app-server/tests/suite/v2/process_exec.rs` for spawn
    acknowledgement before exit, buffered output caps, and process
    termination.

  • Add remote plugin skill read API (#20150)
    ## Summary
    
    Adds an app-server `plugin/skill/read` method for remote plugin skill
    markdown. The new method calls the plugin-service skill detail endpoint
    and returns `skill_md_contents`, so clients can preview skills for
    remote plugins before the bundle is installed locally.
    
    ## Why
    
    Uninstalled remote plugin skills do not have local `SKILL.md` files.
    Without an on-demand remote read, the desktop plugin details UI cannot
    render the skill details modal for those skills.

  • Stop emitting item/fileChange/outputDelta output delta notifications (#20471)
    ## Why
    
    `item/fileChange/outputDelta` text output was only the tool's summary or
    error text and not used by client surfaces.
    
    We keep `item/fileChange/outputDelta` in the app-server protocol as a
    deprecated compatibility entry, but the server no longer emits it.
    
    ## What changed
    
    - stop the `apply_patch` runtime from emitting `ExecCommandOutputDelta`
    events
    - simplify `item_event_to_server_notification` so command output deltas
    always map to `item/commandExecution/outputDelta`
    - remove the app-server bookkeeping that tried to detect whether an
    output delta belonged to a file change
    - mark `item/fileChange/outputDelta` as a deprecated legacy protocol
    entry in the v2 types, schema, and README
    - simplify the file-change approval tests so they only wait for
    completion instead of expecting output-delta notifications

  • realtime: rename provider session ids (#20361)
    ## Summary
    
    Codex is repurposing `session` to mean a thread group, so the realtime
    provider session id should no longer use `session_id` / `sessionId` in
    Codex-facing protocol payloads. This PR renames that provider-specific
    field to `realtime_session_id` / `realtimeSessionId` and intentionally
    breaks clients that still send the old field names.
    
    ## What Changed
    
    - Renamed realtime provider session fields in `ConversationStartParams`,
    `RealtimeConversationStartedEvent`, and `RealtimeEvent::SessionUpdated`.
    - Renamed app-server v2 realtime request and notification fields to
    `realtimeSessionId`.
    - Removed legacy serde aliases for `session_id` / `sessionId`; clients
    must send the new names.
    - Propagated the rename through core realtime startup, app-server
    adapters, codex-api websocket handling, and TUI realtime state.
    - Regenerated app-server protocol schema/TypeScript outputs and updated
    app-server README examples.
    - Kept upstream Realtime API concepts unchanged: provider `session.id`
    parsing and `x-session-id` headers still use the upstream wire names.
    
    ## Testing
    
    - CI is running on the latest pushed commit.
    - Earlier local verification on this PR:
      - `cargo test -p codex-protocol`

    The generated schema files account for most of the raw diff, these files
    have the core change:
    
    - `hooks/src/engine/discovery.rs` builds the inventory entries during
    hook discovery while leaving runtime handlers focused on execution.
    - `app-server/src/codex_message_processor.rs` wires `hooks/list` into
    the app-server flow for each requested `cwd`.
    - `app-server-protocol/src/protocol/v2.rs` defines the new v2
    request/response payloads exposed on the wire.
    
    ### Core Changes
    
    `core/src/plugins/manager.rs` adds `plugins_for_layer_stack(...)` so
    `skills/list` and `hooks/list`can resolve plugin state for each
    requested `cwd`

  • [app-server] type client response payloads (#20050)
    ## Why
    
    `pr17088` adds typed server-originated request/response plumbing, but
    successful client responses are still erased into bare JSON-RPC `result`
    values before app-server can make any typed decision about them.
    
    This precursor PR keeps successful client responses typed until the
    outgoing response seam. It is intentionally limited to
    protocol/app-server plumbing so the analytics behavior change can review
    separately on top.
    
    ## What changed
    
    - Add `ClientResponsePayload` as the pre-serialization client response
    body type.
    - Route app-server successful response paths through the typed payload
    seam while preserving existing handler-local analytics behavior.
    - Keep `InterruptConversation` JSON-RPC-only because it has no
    `ClientResponse` variant.
    - Move the new payload conversion tests into a dedicated protocol test
    module.
    
    ## Verification
    
    - `cargo check -p codex-app-server`
    - `cargo test -p codex-app-server-protocol`
  • [codex-analytics] ingest server requests and responses (#17088)
    ## Why
    
    Codex analytics needs a typed seam for app-server-originated
    request/response traffic so future tool-approval analytics can consume
    those facts without adding bespoke callsite tracking each time. Server
    responses arrive as JSON-RPC `id + result` payloads, so analytics has to
    reconstruct the matching typed response from the original typed request
    while that request context still exists in app-server.
    
    This also puts analytics on the app-server outbound path, which needs to
    avoid keeping the runtime alive during shutdown. The final ownership fix
    keeps the normal strong auth-manager retention in analytics and makes
    the external-auth refresh bridge hold a weak back-reference to
    `OutgoingMessageSender`, breaking the runtime cycle at the bridge
    boundary instead of exposing retention policy through the analytics
    client API.
    
    ## What changed
    
    - Adds typed `ServerRequest` and `ServerResponse` analytics facts, plus
    `AnalyticsEventsClient::track_server_request` and
    `track_server_response`.
    - Renames the existing client-side facts to `ClientRequest` and
    `ClientResponse` so reducers can distinguish client-to-server traffic
    from server-to-client traffic.
    - Adds `ServerRequest::response_from_result`, allowing a stored typed
    request to decode the matching typed server response from a raw JSON-RPC
    result payload.
    - Threads `AnalyticsEventsClient` through `OutgoingMessageSender` and
    records targeted server requests, replayed targeted requests, and
    matching targeted responses with the responding connection id needed for
    correlation.
    - Intentionally leaves broadcast server requests/responses out of
    analytics for now because the current model is per connection, while
    broadcasts fan one logical request out across multiple connections.
    - Breaks the app-server shutdown cycle by storing
    `Weak<OutgoingMessageSender>` in `ExternalAuthRefreshBridge` and
    upgrading it only when an external-auth refresh is actually requested.
    - Keeps reducer ingestion of the new server-side facts as no-ops for
    now; this PR is plumbing for later tool-approval analytics work.
    
    ## Verification
    
    - `cargo test -p codex-analytics`
    - `cargo test -p codex-app-server outgoing_message::tests::`
    - Covers typed-response reconstruction plus the targeted, replayed,
    broadcast-exclusion, and response-attribution analytics paths.
    
    ## Follow-up
    
    This PR intentionally stops at ingestion plumbing, so `ServerRequest`
    and `ServerResponse` facts are still reducer no-ops. Once a follow-up PR
    adds real downstream analytics output for those facts:
    
    - replace the temporary pre-reducer observation seam with reducer tests
    for the emitted event shape;
    - add end-to-end coverage in `app-server/tests/suite/v2/analytics.rs`
    for the real app-server workflow and captured analytics payload;
    - remove the temporary sender-level observer tests added here in favor
    of the real-output coverage above.

  • feat: expose provider capability bounds to app server clients (#20049)
    follow up of #19442. The app server now exposes provider-derived bounds
    through a new v2 `modelProvider/read` method. The response reports the
    configured provider map key as `modelProvider` and returns the effective
    capability booleans so clients can align their UI with the same
    provider-owned limits used by core.
  • app-server: notify clients of remote-control status changes (#19919)
    ## Why
    
    Remote-control app-server enrollments have both an internal server id
    and the environment id exposed to remote-control clients. App-server
    clients need one current status snapshot that says whether remote
    control is usable and which environment id, if any, is exposed.
    
    A temporary websocket disconnect is not itself an identity change.
    Account changes, stale enrollment invalidation, successful
    re-enrollment, and missing ChatGPT auth are meaningful status changes.
    Disabled remote control remains `disabled` regardless of auth or SQLite
    state. SQLite startup failure disablement and enrollment persistence
    failures are handled in #20068; this PR reports the resulting effective
    status to clients.
    
    ## What changed
    
    - Adds v2 `remoteControl/status/changed` carrying `state` and
    `environmentId`.
    - Adds `RemoteControlConnectionState` values: `disabled`, `connecting`,
    `connected`, and `errored`.
    - Exposes remote-control status updates through `RemoteControlHandle`
    using a Tokio watch channel.
    - Always sends the current remote-control status snapshot to newly
    initialized app-server clients.
    - Broadcasts status changes to initialized app-server clients when state
    or environment id changes.
    - Treats missing ChatGPT auth as an `errored` status while leaving it
    retryable because auth can change at runtime.
    - Clears `environmentId` when enrollment is cleared for account changes,
    auth loss, stale backend invalidation, or disabled remote control.
    - Updates app-server protocol schema fixtures, generated TypeScript,
    app-server README, remote-control tests, and TUI exhaustive notification
    matches.

  • app-server: run initialized rpcs with keyed serialization (#17373)
    ## Why
    
    Initialized app-server RPCs no longer need to bottleneck behind one
    request processor path. Running them concurrently improves
    responsiveness, but several request families still mutate shared state
    or depend on ordered side effects. Those stateful families need an
    auditable serialization contract so concurrency does not reorder thread,
    config, auth, command, watcher, MCP, or similar state transitions.
    
    This PR keeps that boundary explicit: stateful work is serialized by the
    smallest useful key, while intentionally read-only or externally
    concurrent work remains unkeyed. In particular, `thread/list` and
    `thread/turns/list` explicitly have no serialization because they
    primarily read append-only rollout storage and should continue to be
    served concurrently.
    
    ## What changed
    
    - Adds `ClientRequest::serialization_scope()` in `app-server-protocol`
    and requires every client request definition to declare its
    serialization behavior.
    - Introduces keyed request scopes for thread, thread path, command exec
    process, fuzzy search session, fs watch, MCP OAuth, and global state
    buckets such as config, account auth, memory, and device keys.
    - Routes initialized app-server RPCs through per-key FIFO serialization
    while allowing unkeyed initialized requests to run concurrently.
    - Cancels in-flight initialized RPC work when the connection disconnects
    or the app-server exits so spawned request tasks do not outlive their
    session.
    - Adds focused coverage for representative keyed and unkeyed
    serialization scopes, including explicitly concurrent
    `thread/turns/list` behavior.
    
    ## Validation
    
    - Added protocol tests for representative keyed serialization scopes and
    intentionally unkeyed request families.
    - Added app-server request serialization tests covering per-key FIFO
    behavior, concurrent unkeyed execution, disconnect shutdown, and config
    read-after-write ordering.
    - Local focused protocol validation after the latest rebase is currently
    blocked by packageproxy failing to resolve locked `rustls-webpki
    0.103.13`; CI is expected to provide the full validation signal.
  • app-server-protocol: mark permission profiles experimental (#19899)
    ## Why
    
    `PermissionProfile` is now the canonical internal permissions
    representation, but the app-server wire shape is still intentionally
    unstable while the migration continues. Stable app-server clients should
    not see or generate code for these fields until the wire format settles.
    
    ## What changed
    
    - Marks every app-server v2 field that sends `PermissionProfile` as
    experimental, including `command/exec`, `thread/start`, `thread/resume`,
    `thread/fork`, and `turn/start` request/response payloads.
    - Enables per-field experimental inspection for `command/exec`, so
    `permissionProfile` is gated without making the entire method
    experimental.
    - Fixes the generated TypeScript schema filter to be comment-aware. The
    previous scanner treated apostrophes inside doc comments as string
    delimiters, so some experimental fields leaked into stable TypeScript
    even though stable JSON was filtered correctly.
    
    ## Verification
    
    - `cargo test -p codex-app-server-protocol`

  • Add goal app-server API (2 / 5) (#18074)
    Adds the app-server v2 goal API on top of the persisted goal state from
    PR 1.
    
    ## Why
    
    Clients need a stable app-server surface for reading and controlling
    materialized thread goals before the model tools and TUI can use them.
    Goal changes also need to be observable by app-server clients, including
    clients that resume an existing thread.
    
    ## What changed
    
    - Added v2 `thread/goal/get`, `thread/goal/set`, and `thread/goal/clear`
    RPCs for materialized threads.
    - Added `thread/goal/updated` and `thread/goal/cleared` notifications so
    clients can keep local goal state in sync.
    - Added resume/snapshot wiring so reconnecting clients see the current
    goal state for a thread.
    - Added app-server handlers that reconcile persisted rollout state
    before direct goal mutations.
    - Updated the app-server README plus generated JSON and TypeScript
    schema fixtures for the new API surface.
    
    ## Verification
    
    - Added app-server v2 coverage for goal get/set/clear behavior,
    notification emission, resume snapshots, and non-local thread-store
    interactions.
  • permissions: make legacy profile conversion cwd-free (#19414)
    ## Why
    
    The profile conversion path still required a `cwd` even when it was only
    translating a legacy `SandboxPolicy` into a `PermissionProfile`. That
    made profile producers invent an ambient `cwd`, which is exactly the
    anchoring we are trying to remove from permission-profile data. A legacy
    workspace-write policy can be represented symbolically instead: `:cwd =
    write` plus read-only `:project_roots` metadata subpaths.
    
    This PR creates that cwd-free base so the rest of the stack can stop
    threading cwd through profile construction. Callers that actually need a
    concrete runtime filesystem policy for a specific cwd still have an
    explicitly named cwd-bound conversion.
    
    ## What Changed
    
    - `PermissionProfile::from_legacy_sandbox_policy` now takes only
    `&SandboxPolicy`.
    - `FileSystemSandboxPolicy::from_legacy_sandbox_policy` is now the
    symbolic, cwd-free projection for profiles.
    - The old concrete projection is retained as
    `FileSystemSandboxPolicy::from_legacy_sandbox_policy_for_cwd` for
    runtime/boundary code that must materialize legacy cwd behavior.
    - Workspace-write profiles preserve `CurrentWorkingDirectory` and
    `ProjectRoots` special entries instead of materializing cwd into
    absolute paths.
    
    ## Verification

  • permissions: make profiles represent enforcement (#19231)
    ## Why
    
    `PermissionProfile` is becoming the canonical permissions abstraction,
    but the old shape only carried optional filesystem and network fields.
    It could describe allowed access, but not who is responsible for
    enforcing it. That made `DangerFullAccess` and `ExternalSandbox` lossy
    when profiles were exported, cached, or round-tripped through app-server
    APIs.
    
    The important model change is that active permissions are now a disjoint
    union over the enforcement mode. Conceptually:
    
    ```rust
    pub enum PermissionProfile {
        Managed {
            file_system: FileSystemSandboxPolicy,
            network: NetworkSandboxPolicy,
        },
        Disabled,
        External {
            network: NetworkSandboxPolicy,
        },
    }
    ```
    
    This distinction matters because `Disabled` means Codex should apply no
    outer sandbox at all, while `External` means filesystem isolation is
    owned by an outside caller. Those are not equivalent to a broad managed
    sandbox. For example, macOS cannot nest Seatbelt inside Seatbelt, so an
    inner sandbox may require the outer Codex layer to use no sandbox rather
    than a permissive one.
    
    ## How Existing Modeling Maps
    
    Legacy `SandboxPolicy` remains a boundary projection, but it now maps
    into the higher-fidelity profile model:
    
    - `ReadOnly` and `WorkspaceWrite` map to `PermissionProfile::Managed`
    with restricted filesystem entries plus the corresponding network
    policy.
    - `DangerFullAccess` maps to `PermissionProfile::Disabled`, preserving
    the “no outer sandbox” intent instead of treating it as a lax managed
    sandbox.
    - `ExternalSandbox { network_access }` maps to
    `PermissionProfile::External { network }`, preserving external
    filesystem enforcement while still carrying the active network policy.
    - Split runtime policies that legacy `SandboxPolicy` cannot faithfully
    express, such as managed unrestricted filesystem plus restricted
    network, stay `Managed` instead of being collapsed into
    `ExternalSandbox`.
    - Per-command/session/turn grants remain partial overlays via
    `AdditionalPermissionProfile`; full `PermissionProfile` is reserved for
    complete active runtime permissions.
    
    ## What Changed
    
    - Change active `PermissionProfile` into a tagged union: `managed`,
    `disabled`, and `external`.
    - Keep partial permission grants separate with
    `AdditionalPermissionProfile` for command/session/turn overlays.
    - Represent managed filesystem permissions as either `restricted`
    entries or `unrestricted`; `glob_scan_max_depth` is non-zero when
    present.
    - Preserve old rollout compatibility by accepting the pre-tagged `{
    network, file_system }` profile shape during deserialization.
    - Preserve fidelity for important edge cases: `DangerFullAccess`
    round-trips as `disabled`, `ExternalSandbox` round-trips as `external`,
    and managed unrestricted filesystem + restricted network stays managed
    instead of being mistaken for external enforcement.
    - Preserve configured deny-read entries and bounded glob scan depth when
    full profiles are projected back into runtime policies, including
    unrestricted replacements that now become `:root = write` plus deny
    entries.
    - Regenerate the experimental app-server v2 JSON/TypeScript schema and
    update the `command/exec` README example for the tagged
    `permissionProfile` shape.
    
    ## Compatibility
    
    Legacy `SandboxPolicy` remains available at config/API boundaries as the
    compatibility projection. Existing rollout lines with the old
    `PermissionProfile` shape continue to load. The app-server
    `permissionProfile` field is experimental, so its v2 wire shape is
    intentionally updated to match the higher-fidelity model.
