## Why
Cloud-managed `requirements.toml` should be able to define the managed
permission profiles a client may select and constrain that selectable
set without requiring local user config to recreate the profile catalog.
This keeps requirements focused on restrictions. The selected default
remains a config or session choice, while requirements contribute the
managed profile bodies and `allowed_permissions` allowlist that the
config-loading boundary validates before a resolved runtime
`PermissionProfile` is installed.
## What changed
- Add `requirements.toml` support for a managed permission-profile
catalog plus its allowlist:
```toml
allowed_permissions = ["review", "build"]
[permissions.review]
extends = ":read-only"
[permissions.build]
extends = ":workspace"
```
- Merge requirements-defined profile bodies into the effective
permission catalog and reject profile ids that collide with
config-defined profiles.
- Validate that every `allowed_permissions` entry resolves to a built-in
or catalog profile before selection uses it.
- Preserve allowed configured named-profile selections. When a
configured named profile is disallowed, fall back to the first allowed
requirements profile with a startup warning.
- Keep built-in selections and the stock trust-based `:read-only` /
`:workspace` fallback path intact when no permission profile is
explicitly selected.
- Centralize the managed catalog and allowlist selection path in
`EffectivePermissionSelection` so the requirements boundary is visible
in config loading.
- Surface `allowedPermissions` through `configRequirements/read`, and
update the generated app-server schema fixtures plus the app-server
README.
## Validation
- `cargo test -p codex-config`
- `cargo test -p codex-core system_requirements_`
- `cargo test -p codex-core system_allowed_permissions_`
- `cargo test -p codex-app-server-protocol`
- `just write-app-server-schema`
## Related work
- Uses merged permission-profile inheritance support from #22270 and
#23705.
- Kept separate from the in-flight permission profile listing API in
#23412.
Add owning plugin id to MCP tool call items so we can better filter them
at plugin level.
## Summary
- add optional `plugin_id` to MCP tool-call items and legacy begin/end
events
- propagate plugin metadata into emitted core items and app-server v2
`ThreadItem::McpToolCall`
- preserve plugin ids through app-server replay/redaction paths and
regenerate v2 schema fixtures
## Testing
- `just write-app-server-schema`
- `just fmt`
- `just fix -p codex-core`
- `cargo test -p codex-protocol -p codex-app-server-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core mcp_tool_call_item_includes_plugin_id --lib`
- `cargo check -p codex-tui --tests`
- `cargo check -p codex-app-server --tests`
- `git diff --check`
## Notes
- `just fix -p codex-core` completed with two non-fatal
`too_many_arguments` warnings on the touched MCP notification helpers.
- A broader `cargo test -p codex-core` run passed core unit tests, then
hit shell/sandbox/snapshot failures in the integration target.
- A broader app-server downstream run hit the existing
`in_process::tests::in_process_start_clamps_zero_channel_capacity` stack
overflow; `cargo test -p codex-exec` also hit the existing sandbox
expectation mismatch in
`thread_lifecycle_params_include_legacy_sandbox_when_no_active_profile`.
## 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`.
- Adds an explicit vertical marketplace kind for plugin/list that
fail-open fetches collection=vertical only when full remote plugins are
disabled.
- Renames the global remote marketplace/cache identity to
openai-curated-remote and materializes remote installs with backend
release versions and app manifests.
## Summary
- Coerce `path: ""` to `None` at the v2 protocol params deserialization
boundary for `thread/resume` and `thread/fork`.
- Restore the pre-ThreadStore running-thread resume behavior: if
`threadId` is already running, rejoin it by id and treat a non-empty
`path` only as a consistency check; otherwise cold resume keeps `history
> path > threadId` precedence.
- Add protocol, resume, and fork regression coverage for empty path
payloads; refresh app-server schema fixtures for the clarified params
docs.
## Tests
- `just fmt`
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol
thread_path_params_deserialize_empty_path_as_none`
- `cargo test -p codex-app-server-protocol --test schema_fixtures`
- `cargo test -p codex-app-server empty_path`
- `RUST_MIN_STACK=8388608 cargo test -p codex-app-server --test all
thread_resume_rejects_mismatched_path_for_running_thread_id`
- `RUST_MIN_STACK=8388608 cargo test -p codex-app-server --test all
thread_resume_uses_path_over_non_running_thread_id`
## 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.
## Why
`model_auto_compact_token_limit` has only been able to budget the full
active context. That makes it hard to set a small "growth since
compaction" budget for sessions that preserve a large carried window
prefix: the preserved prefix can consume the whole budget and force
immediate repeated compaction.
This PR adds an opt-in `body_after_prefix` scope so callers can apply
`model_auto_compact_token_limit` to sampled output and later growth
after the current carried prefix, while still forcing compaction before
the full model context window is exhausted.
## What changed
- Adds `AutoCompactTokenLimitScope` with the existing `total` behavior
as the default and a new `body_after_prefix` mode:
[`config_types.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/protocol/src/config_types.rs#L24-L37).
- Threads `model_auto_compact_token_limit_scope` through config loading,
`Config`, `core-api`, and app-server v2 schema/TypeScript generation.
- Records the first observed input-token count for a `body_after_prefix`
compaction window and uses it as the baseline when deciding whether the
scoped auto-compaction budget is exhausted:
[`turn.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/core/src/session/turn.rs#L743-L781).
- Keeps a hard context-window cap in `body_after_prefix`, so scoped
budgeting cannot let the active context overrun the usable window.
## Verification
Added compact-suite coverage for the two key behaviors:
`body_after_prefix` does not re-compact just because the carried prefix
is larger than the scoped budget, and it still compacts when the total
active context reaches the configured context window:
[`compact.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/core/tests/suite/compact.rs#L3003-L3128).
## 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`
- `RUST_MIN_STACK=8388608 cargo test -p codex-tui`

* #23368
* __->__ #23360
## 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`.
- Companion webview PR: https://github.com/openai/openai/pull/915672
## 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.
## Summary
- Add optional image detail to user image inputs across core, app-server
v2, thread history/event mapping, and the generated app-server
schemas/types.
- Preserve requested detail when serializing Responses image inputs:
omitted detail stays on the existing `high` default, while explicit
`original` keeps local images on the original-resolution path.
- Support `high`/`original` consistently for tool image outputs,
including MCP `codex/imageDetail`, code-mode image helpers, and
`view_image`.
## 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.

[//]: # (BEGIN SAPLING FOOTER)
Stack created with [Sapling](https://sapling-scm.com). Best reviewed
with [ReviewStack](https://reviewstack.dev/openai/codex/pull/22792).
* #22795
* __->__ #22792
## 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.

## Summary
- reserve an explicit opaque `desktop` namespace in `ConfigToml`
- expose `desktop` directly in the app-server v2 `config/read` response
- keep `config/value/write` and `config/batchWrite` as the only mutation
seam for paths like `desktop.someKey`
- regenerate the config/app-server schema outputs and document the new
contract
## Why
The desktop settings work wants one durable, user-editable home for
app-owned preferences in `~/.codex/config.toml`, without forcing Rust to
model every individual desktop setting key.
This PR is only the enabling Rust/app-server layer. It gives the
Electron app a first-class config namespace it can read and write
through the existing config APIs, while leaving the actual desktop
migration to the app PR.
## Behavior and design notes
- **Opaque but explicit:** `desktop` is first-class at the typed config
root, while its children remain app-owned and open-ended.
- **Strict validation still works:** arbitrary nested `desktop.*` keys
are accepted instead of being rejected as unknown config.
- **Existing config APIs stay the seam:** `config/read` returns the bag,
and dotted writes such as `desktop.someKey` continue to flow through
`config/value/write` / `config/batchWrite` rather than a bespoke RPC.
- **No new consumer behavior:** Core/TUI do not start depending on
desktop preferences. This only preserves and exposes the namespace for
callers that intentionally use it.
- **Same persistence machinery:** hand-edited `config.toml` keeps using
the existing TOML edit/write path; this PR does not introduce a second
serializer or side channel.
- **TOML-friendly values:** the namespace is intended for ordinary
JSON-shaped setting values that map cleanly into TOML: strings, numbers,
booleans, arrays, and nested object/table values. This PR does not add
special handling for TOML-only edge cases such as datetimes.
## Layering semantics
Reads keep using the ordinary effective config pipeline, so `desktop`
participates in the same layered `config/read` behavior as the rest of
`ConfigToml`. Writes still target user config through the existing
config service.
## Why this is the shape
The alternative would be teaching Rust about each desktop setting as it
is added. That would make ordinary app preferences into a cross-repo
change, which is exactly the coupling we want to avoid.
This keeps the contract small:
1. Rust owns one opaque `desktop` namespace in `config.toml`.
2. The desktop app owns the schema and meaning of individual keys inside
it.
3. The existing config APIs remain the transport and mutation surface.
That is the piece the desktop settings PR needs in order to move forward
cleanly.
## Verification
- `cargo test -p codex-config strict_config_accepts_opaque_desktop_keys`
- `cargo test -p codex-core
desktop_toml_round_trips_opaque_nested_values`
- `cargo test -p codex-core config_schema_matches_fixture`

Adds plugin/share/checkout to turn a shared remote plugin into a local
working copy under ~/plugins/<name>.
Registers the copy in the managed personal marketplace and records the
remote-to-local mapping for later share/save flows.
---------
Co-authored-by: Codex <noreply@openai.com>
## Why
Enterprise-managed hook policy needs a narrow way to require Codex to
ignore user-controlled lifecycle hooks without adopting the broader
trust-precedence model from earlier hook work. This keeps the policy
anchored in `requirements.toml`, so admins can opt into managed hooks
only while normal `config.toml` files cannot enable the restriction
themselves.
## What changed
- Added `allow_managed_hooks_only` to the requirements data flow and
preserved explicit `false` values.
- Also adds it to /debug-config
- Marked MDM, system, and legacy managed config layers as managed for
hook discovery.
- Updated hook discovery so `allow_managed_hooks_only = true`:
- keeps managed requirements hooks and managed config-layer hooks,
- skips user/project/session `hooks.json` and `[hooks]` entries with
concise startup warnings,
- skips current unmanaged plugin hooks,
- ignores any `allow_managed_hooks_only` key placed in ordinary
`config.toml` layers.
- Adds localVersion to plugin summaries and remoteVersion to share
context, including generated API schemas.
- Hydrates local and remote plugin versions from manifests and remote
release metadata.
- Adds default-on plugin_sharing gate for shared-with-me listing and
plugin/share/save, with disabled-path errors
and focused coverage.
Makes plugin summaries use config-style plugin@marketplace IDs while
exposing backend remote IDs separately as remotePluginId.
Also fix the consistency issue of REMOTE_SHARED_WITH_ME_MARKETPLACE_NAME
Expose discoverability and full share principals in share context, carry
roles through save/updateTargets, hydrate local shared plugin reads, and
keep share URLs only under plugin.shareContext.
Requires discoverability on plugin/share/updateTargets so the server can
manage workspace link access consistently, including auto-adding the
workspace principal for UNLISTED.
Also rejects LISTED on share creation and blocks client-supplied
workspace principals while preserving response parsing for LISTED.
## 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-app-server-protocol`
- `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.
## Why
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
## Verification
- `cargo test -p codex-app-server outgoing_message --manifest-path
codex-rs/Cargo.toml`
- `cargo test -p codex-app-server-protocol guardian --manifest-path
codex-rs/Cargo.toml`
- `cargo test -p codex-tui guardian --manifest-path codex-rs/Cargo.toml`
- `cargo test -p codex-analytics analytics_client_tests --manifest-path

* #18747
* #17090
* #17089
* #20514
## 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.
Adds marketplaceKinds to plugin/list for local, workspace-directory, and
shared-with-me; omitted params keep default local plus gated global
behavior, while explicit kinds are exact.
Exposes shareContext on plugin summaries from local share mappings and
remote workspace/shared responses, including remotePluginId and nullable
creator metadata.
Adds shared-with-me listing through /ps/plugins/workspace/shared,
renames the workspace remote namespace to workspace-directory, and keeps
direct remote read/share/install/update/delete paths gated by plugins
rather than remote_plugin.
## 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.
Extends `plugin/share/save` to accept optional discoverability and
shareTargets while uploading plugin contents, and adds
`plugin/share/updateTargets` for share-only target updates without
re-uploading.
## Summary
- Add plugin manifest keywords to core plugin marketplace/detail models
- Expose keywords on app-server v2 PluginSummary and generated
schema/types
- Populate keywords in plugin/list and plugin/read responses for local
plugins
Depends on https://github.com/openai/openai/pull/891087

## Why
`codex-rs/app-server-protocol/src/protocol/v2.rs` had grown into a
single ~12k-line definition file for the entire app-server v2 API.
This is purely a mechanical refactor to break up the monolithic `v2.rs`
file that contains all app-server API v2 types into more modular files,
grouped by resource (e.g. account, thread, turn, etc.).
`just write-app-server-schema` shows no real changes, so we can be sure
that this is purely an internal organizational change.
## What changed
- Replaced the monolithic `protocol/v2.rs` with a `protocol/v2/` module
tree and a small `mod.rs` that only declares and reexports modules.
- Grouped v2 API definitions by conceptual owner, including `account`,
`apps`, `collaboration_mode`, `command_exec`, `config`, `device_key`,
`experimental_feature`, `feedback`, `fs`, `hook`, `item`, `mcp`,
`model`, `notification`, `permissions`, `plugin`, `process`, `realtime`,
`review`, `thread`, `thread_data`, `turn`, and `windows_sandbox`.
- Moved v2 tests into `protocol/v2/tests.rs` so `mod.rs` stays small.
- Kept shared protocol helpers in `protocol/v2/shared.rs`, including the
enum mirroring macro and common cross-resource types.
- Co-located resource-specific notifications and server-request payloads
with the modules that own those resources.
- Regenerated app-server protocol schema fixtures. The schema diffs are
non-semantic newline-only changes after the refactor.
## Verification
- `cargo check -p codex-app-server-protocol`
- `cargo test -p codex-app-server-protocol`
- `just write-app-server-schema`
