## What changed
Add `biometricType` to `userVerification/verify` responses as context alongside the signed `proof`. Successful Touch ID protected signing reports `"fingerprint"`; an unknown method reports `null`. Responses from older servers that omit the field remain supported.
Carry the native method through the verification provider and app-server protocol, and update the experimental protocol exports and API documentation.
## Testing
Add coverage for responses without `biometricType` and for returning `"fingerprint"` separately from the proof. Update existing verification coverage to check the `null` case.

## Why
Gateway OAuth reads and logins previously used only the current provider, preventing clients from authorizing another configured provider without changing the default.
## What changed
- Add optional `modelProvider` params to `account/gatewayOAuth/read` and `account/gatewayOAuth/login`, preserving current-provider behavior for omitted or null params and selectors.
- Validate explicit providers against current managed policy without changing the default or any thread's provider.
- Retain readiness state across providers and send `account/gatewayOAuth/changed` notifications for every configured provider sharing the changed credential.
- Update protocol schemas, TypeScript types, Python models, and documentation.
## Testing
Add coverage for non-default provider login, retained readiness when alternating providers, notifications for shared credentials without starting login, and legacy TypeScript request compatibility.
GitOrigin-RevId: cfd472c322b821fe36b8c133a8de774f4ba48534
## What changed
Add optional `contentTokenCount` metadata to `item/completed` notifications, carrying the producer-supplied token count for each completed assistant message in default and plan modes. Counts include any sampled footer and are `null` when unavailable.
Keep this telemetry separate from stored thread items and omit it from subsequent model requests. Update the protocol schemas and generated TypeScript and Python types.
## Testing
Add coverage for per-message counts, including zero, in default and plan modes; missing and malformed metadata; backward-compatible notification decoding; and exclusion from subsequent model requests.
GitOrigin-RevId: 35973037a42650fa2d7569da8e88cb81215cf971
## What changed
Expose `thread/guardianReview` to review an idle thread's final injected `exec_command` without executing it. Return the call ID and Guardian assessment, or `null` for the assessment when exec policy skips approval.
Subscribe the requesting connection to the thread, enforce input and model-provider restrictions, and cancel an in-flight review when the connection disconnects so the thread is released promptly.
## Testing
Add integration coverage for assessment responses, policy-skipped reviews, model-provider enforcement, and WebSocket disconnect cancellation.
GitOrigin-RevId: e8ad5598e8f101a937447ebe26136310bb76c8d1
## Why
Existing chats retain their provider configuration when the selected provider changes. Reject resume and input until the configured provider matches the chat, while keeping history readable and allowing recovery after configuration is restored.
## What changed
- Validate saved providers before applying resume overrides, preserving the provider when only model or reasoning settings change.
- Check the current provider selection, including profiles and launch overrides, before accepting input. Reject input when configuration cannot be loaded.
- Return structured `ModelProviderError` data for provider mismatches, missing definitions, and policy conflicts, with generated JSON Schema, TypeScript, and Python types.
## Testing
Add coverage for override bypass prevention, provider restoration, readable history after rejection, and blocked requests sending no inference traffic. Verify schema fields and Python round trips match the error wire format.
GitOrigin-RevId: 051f97c3815c547d8411c71b770df30eae969f68
## Why
Slow consumers can lose process output or block control replies when the in-process event queue fills. Descendants can also keep output streams open after the child exits, leaving clients unable to tell whether captured output is complete.
## What changed
- Require delivery of `process/outputDelta` and `process/exited` notifications, while allowing process request replies to proceed when event delivery is blocked.
- Exclude time spent delivering output to slow clients from the post-exit drain budget, and drain queued bytes after the deadline closes a stream.
- Keep draining after an output byte cap is reached so the child can finish writing; abort each stream's reader when its drain deadline expires.
- Add optional `outputDrainTimedOut` to `process/exited` and generated bindings. Report incomplete output separately from the child's exit code, treating a fully captured requested byte cap as complete.
- Deliver the exit notification before moving Windows console cleanup to a blocking task.
## Testing
Add regression coverage for full event queues, stalled consumers issuing process control requests, slow output delivery, inherited pipes, output caps, Windows console descendants, and compatibility with exit notifications that omit `outputDrainTimedOut`.
GitOrigin-RevId: 04cfeea5daa7c2b833cdec3f1fff7efeb4d1a86e
## Why
Older servers can omit thread item timestamps. The TypeScript contract should accept those responses while still allowing explicit `null` values.
## What changed
Mark `ThreadItem.startedAtMs` and `ThreadItem.completedAtMs` as optional nullable fields. Update the generated TypeScript and precomputed stable and experimental exports, and allow these fields in the optional-nullable export check.
GitOrigin-RevId: 186be7aa45a3e7c65f133b1e320809a9912ff1f3
## Why
ENT26 plans are billed directly in dollars, so credit estimates and credit-weighted breakdowns do not describe their thread usage.
## What changed
- Expose optional `nativeUsageUsdMicros` in app-server `ThreadUsage` responses and generated schemas and SDK types. Missing native usage means unknown, not zero.
- Enable ENT26 usage fetching and display native dollar amounts in `/status`, the status line, terminal titles, and the agents overview. Hide credits and omit credit-weighted `/status` breakdowns for these plans.
- Use native dollar amounts when tracking post-turn usage settlement for ENT26 plans.
## Testing
Add coverage for native usage forwarding, ENT26 billing displays, and settlement polling with stale, missing, or zero dollar amounts.
GitOrigin-RevId: ca8ea98141a66bdf0a27feb9f58f67822b821f5f
## What changed
- Add an optional `name` to `AdditionalContextEntry` across the protocol, app-server schemas, and generated clients.
- Accept names matching `[a-z][a-z0-9_]{0,63}` only for `untrusted` context. Reject invalid names and names on `application` context before admitting turn input, returning invalid-request errors from `turn/start` and `turn/steer`.
- Preserve existing model-input rendering and deduplicate context when only its name changes.
## Testing
Add coverage for valid name boundaries, callers that omit `name`, invalid-name rejection without admitting input, and deduplication across name changes.
GitOrigin-RevId: 2caffa6fddd40ddb178733b335f520f317239edd
## What changed
Remove eight tests covering experimental API schema filtering and marking,
end-of-file unified diffs, MCP prompt auto-approval, and local-link regex
initialization. Remove the associated unused test imports and regex coverage
comment. Runtime behavior is unchanged.
GitOrigin-RevId: 91f59cab82393d43000eadf4e7c55e3a6ec2aa14
## What changed
- Carry opaque `review_target` values through misalignment errors and expose optional `reviewTarget` in the app-server protocol and generated clients. Preserve the value verbatim and redact it from debug output.
- Keep target-based `misalignment_override` metadata on turn requests, preserve it across steering updates, and exclude it from compaction and external MCP metadata. Reject overrides from global Responses metadata while retaining legacy timestamp behavior for per-turn overrides.
## Testing
Extend coverage for error propagation, debug and rollout redaction, steering preservation, and metadata filtering. Verify that automatic compaction omits the review target while turn requests before and after compaction retain it.
GitOrigin-RevId: 8c1abb076a206ff5927a4acc31bd25e3efc2bff9
## Why
New error variants should not prevent older clients from handling app-server errors.
## What changed
- Deserialize unknown `CodexErrorInfo` strings and objects as `Other` in Rust, while preserving known variants and the `"other"` serialization.
- Allow arbitrary strings and objects in the exported JSON schemas and TypeScript type.
- Update Python SDK generation and generated models to accept unknown error strings and object payloads.
## Testing
Add Rust tests for `"other"` round trips, unknown string and object fallbacks, known structured variants, and rejection of null, boolean, numeric, and array values.
GitOrigin-RevId: 40c17896019924b2ef7970ee2205ea0154d0d1b3
## Why
The app server previously rejected OAuth login for enterprise-managed MCP servers. These servers need an explicit sign-in flow that ties saved authorization to the active Codex user and workspace and prevents canceled or superseded attempts from saving credentials.
## What changed
- Enable enterprise sign-in through `mcpServer/oauth/login` for configured servers with a connected thread, trusted IdP registration, and `features.use_xaa` enabled. Scope shared enterprise credentials by user, workspace, issuer, and client ID.
- Add `loginId` to MCP OAuth login responses and completion notifications, preserving compatibility with older servers that omit it.
- Support enterprise login replacement and `account/login/cancel`, wait for callback listener shutdown before replacement, and recheck account and configuration before saving grants. Fence stale attempts across processes and account changes.
- Remove shared enterprise authorization during account logout and `codex mcp logout`, including when the feature is disabled. Continue account logout if enterprise cleanup fails, and invalidate MCP runtimes on account changes.
Start a fresh session after successful enterprise sign-in to use the saved grant.
## Testing
Add regression coverage for login replacement and cancellation, callback port reuse, account changes during setup, cross-process logout invalidation, persisted workspace policy selection, cleanup failures, and responses from older servers without `loginId`.
GitOrigin-RevId: 7ed4caaab4659ed1e67064262cf5cee48e3a26ac
## Why
Device-authenticated verification needs an app response outside automated approval and review. Previously, MCP user-verification requests were always cancelled.
## What changed
- Add typed `openai/userVerification` elicitations carrying a title, description, and challenge through core and app-server.
- Route verification to one connection enabled by trusted host activation. Restrict responses to that owner, exclude requests from replay, and cancel on disconnect or authentication changes, including account switches away and back.
- Return proofs in `content`, discard response metadata, and cancel malformed acceptances. Suppress verification response logging and analytics, and send only a generic verification notice to realtime.
- Keep the mode experimental and exclude it from stable schema exports. Capability advertisement remains disabled, and the TUI cancels verification requests.
## Testing
Add coverage for owner isolation, disconnect and authentication races, proof response handling, automated-review bypass, inactive-host cancellation, stable schema filtering, and realtime payload exclusion. Update the MCP integration test to verify that an activated request holds the tool until the client responds.
GitOrigin-RevId: c8c7b6691a3f7756682bbcca9def1df0d1feb906
## Why
JSON schema exports should be identical across Cargo and Bazel builds.
## What changed
Recursively sort object keys before writing app-server protocol JSON schemas,
while preserving array order.
GitOrigin-RevId: 740c846062f7bae18790e9cf4f30734289ae3056
## What changed
Add `userVerification/status`, `userVerification/enroll`, `userVerification/delete`, and `userVerification/verify` behind the `experimentalApi` capability. Define request, response, proof, and typed error contracts, export their schemas, and document the API.
All four methods currently return `unavailable` with reason `providerUnavailable`; native verification operations are not implemented by this change.
## Testing
Add tests for experimental opt-in, typed provider unavailability, readiness serialization, and rejection of mismatched error reasons and native diagnostic payloads.
GitOrigin-RevId: a858ab41523c5acec7dbf3cfa7fcab693ac44a8c
## What changed
- Accept optional `account/rateLimits/read` capabilities for Luna Reserve support
and lightweight background polling while preserving omitted and `null` params.
- Forward the Luna Reserve capability only for eligible ChatGPT sessions, and let
lightweight polls skip the separate reset-credit detail request.
- Return the backend's `ordinaryUsageAllowed` decision only when its account and
user identity match the active session.
## Testing
- Cover capability defaults, eligible and restricted authentication modes,
lightweight polling, identity filtering, and backend permission handling.
GitOrigin-RevId: f407a3ae1e70e411fdf245f072a16e453f59cd87
## What changed
- Add the experimental `turn/settings/update` method for changing `model`,
`effort`, `summary`, and `serviceTier` on a specific live turn without
changing future turns.
- Report whether the update was applied or the target turn was unavailable,
and reject unsupported fields, disabled feature use, unsafe model changes,
and direct updates to parent-owned subagents.
- Document the method's feature requirements, null handling, and limits.
## Testing
- Cover current-turn and future-turn isolation, rejected and unavailable
targets, feature and capability gates, saved threads, and subagent ownership.
GitOrigin-RevId: 18440f6d7ee5fcd06ae23bd41b22c492b62bb2b5
## What changed
- Add experimental `account/bedrock/discover` and `account/bedrock/setup`
requests to the app-server protocol.
- Define discovery results for AWS profiles and environment credentials, plus
setup inputs for profiles, environment credentials, and access keys.
- Export the new types in the experimental protocol schema. The app server
currently returns `method not found` for both requests because setup is not
yet implemented.
GitOrigin-RevId: 656b4bc11231a417e97041068cecc5dc692786e3
## What changed
- Extend `account/usage/read` with an optional `threadId` request and a
backward-compatible `threadUsage` response containing estimated credits,
optional USD cost, and model, reasoning, speed, and token breakdowns.
- Fetch thread usage for eligible Business and Enterprise plans when `/status`
is opened, then update the rendered status card asynchronously.
- Preserve terminal scrollback when replacing a visible status-card tail, and
append a refreshed card when the original tail can no longer be updated.
## Testing
- Add app-server coverage for authentication, canonical thread IDs,
unavailable billing routes, and malformed IDs.
- Add TUI coverage for usage formatting, stale responses, retries, history
updates, terminal reflow, and scrollback preservation.
GitOrigin-RevId: 49300914b3fba917c0f08e8595363e04e5ba6d37
## What changed
- Add `codex-history` for model-history and persisted-rollout domain types, including `RolloutItem`, `RolloutLine`, `CompactedItem`, and initial/resumed history state.
- Re-export the persisted types from `codex-rollout` and update consumers to use the new crate boundary instead of `codex-protocol`.
- Preserve existing rollout serialization, including legacy numeric compacted-window IDs.
## Testing
- Add `codex-history` tests for rollout JSON round trips, compacted-history compatibility, persisted history modes, and multi-agent version selection.
GitOrigin-RevId: 944daa9297ddd231d3aebbdcb05fff4adf8b4e1b
## Why
Normal app-server protocol builds do not need the `ts-rs` and `schemars`
implementations used to generate schema exports.
## What changed
- Embed compressed stable and experimental TypeScript and JSON schema exports,
and serve the existing export APIs from those artifacts.
- Use no-op schema derives in non-test builds while keeping the real generators
available for fixture regeneration and tests.
- Move schema fixture regeneration behind a Python helper and update
`just write-app-server-schema --experimental` to refresh the experimental
embedded exports.
## Testing
- Verify embedded exports match freshly generated stable and experimental
schemas.
- Verify export options and on-disk output remain compatible.
GitOrigin-RevId: e8536338b457e6eec34bdf29ec0684144bd13734
## What changed
- Apply managed values for `sqlite_home`, `log_dir`, `model_catalog_json`,
`check_for_update_on_startup`, `allow_login_shell`, the report-submission
opt-in, and `windows.sandbox_private_desktop` to the runtime configuration,
with source-aware warnings when they override configured values.
- Expose these values through `configRequirements/read`, return them from
`config/read`, include them in session config locks, and show their sources in
the TUI config debug view.
- Reject app-server writes that overlap an exact managed requirement with
`configRequirementReadonly` while leaving unrelated sibling keys writable.
## Testing
- Cover runtime overrides, requirement API mapping, config reads and writes,
session lock serialization, cross-platform path URIs, and debug output.
GitOrigin-RevId: d4e23b6fd7775c1a6dfe2eab313cdcee50b07081
## What changed
- Add the experimental `thread/searchOccurrences` app-server method for case-insensitive literal search across visible user messages and final assistant messages without replaying the thread.
- Return paginated snippets with UTF-16 match ranges and `thread/turns/list` cursors for navigating to each matching turn.
- Index persisted item types to efficiently select searchable messages from paginated thread history.
## Testing
- Add an app-server integration test covering pagination, steering messages, final-answer selection, Markdown normalization, and UTF-16 offsets.
GitOrigin-RevId: e80160e0f83eb4e5db8de862307085093bee362b
## Why
Clients that account for individual upstream Responses API calls need the exact
usage for each completion rather than accumulated or estimated thread usage.
## What changed
- Add the opt-in `rawResponse/completed` app-server notification with the
`threadId`, `turnId`, `responseId`, and upstream `usage` payload.
- Emit the transient event for normal turns and compaction requests when
`experimentalRawEvents` is enabled. The event is not persisted or replayed,
and `usage` is `null` when the upstream response omits it.
- Export the notification in the app-server schemas and document its behavior.
## Testing
- Cover exact token breakdowns for turn and compaction completions.
GitOrigin-RevId: 49040a060bf1784c1ff1dd62112efb4a778428c4
## What changed
- Add the experimental `environment/status` request for inspecting a configured environment without starting or reconnecting it.
- Report `ready`, `pending`, `disconnected`, or `unknown`, including error details for disconnected and unknown environments.
- Probe ready remote environments over their existing exec-server connection.
## Testing
- Add an app-server integration test covering local and remote ready, pending, disconnected, and unknown environments.
GitOrigin-RevId: 397bba603aa9e0b59008ee6cb7cbde46e357652c
## What changed
- Add an optional `emittedAtMs` field to server notification envelopes and expose the envelope in the generated JSON and TypeScript schemas.
- Populate the Unix timestamp when app-server emits a notification, before transport routing, so every connection in a fan-out receives the same value.
- Keep the field optional for clients decoding notifications from older app-server versions.
## Testing
- Verify notification serialization includes `emittedAtMs`.
- Verify targeted fan-out reuses one timestamp across connections.
GitOrigin-RevId: b379cb11e8e91c558bcd3d46ce459311a6e81e54
## Why
App-server clients that configure named execution environments need to
discover an environment's shell and working directory before selecting
it for a thread or turn. Because the environment can run on a different
operating system than app-server, its working directory is represented
as a canonical `file:` URI rather than a host-local path string. The
probe also needs a bounded response time: an exec-server that completes
initialization but never answers `environment/info` must not hold the
environment serialization queue indefinitely.
## What changed
- Add an experimental `environment/info` app-server RPC for named
environments.
- Route the probe through the managed environment connection and return
target-native shell metadata plus the default working directory as a
`PathUri`.
- Return connection and protocol failures as JSON-RPC errors.
- Bound the exec-server probe response to 30 seconds and remove
timed-out calls from the pending-request table so later environment
mutations can proceed.
- Cover successful responses, omitted working directories, unknown
environments, connection failures, and pending-call cleanup.
## Protocol examples
Request:
```json
{
"id": 42,
"method": "environment/info",
"params": {
"environmentId": "remote-a"
}
}
```
Successful response:
```json
{
"id": 42,
"result": {
"shell": {
"name": "zsh",
"path": "/bin/zsh"
},
"cwd": "file:///workspace"
}
}
```
If the exec-server initializes but does not answer the probe within 30
seconds:
```json
{
"id": 42,
"error": {
"code": -32603,
"message": "failed to get info for environment `remote-a`: exec-server protocol error: timed out waiting for exec-server `environment/info` response after 30s"
}
}
```
## Testing
- App-server integration coverage for successful info (including omitted
`cwd`), unknown environments, and connection failures.
- Exec-server RPC coverage verifying a timed-out call is removed from
the pending-request table.

## What
Server should request:
```
{
"id": 42,
"method": "currentTime/read",
"params": {
"threadId": "11111111-1111-1111-1111-aaaaafdc2c11"
}
}
```
Client should respond with something like:
```rust
{
"id": 42,
"result": {
"currentTimeAt": 1781717655
}
}
```
## Why
Sessions configured with `clock_source = "external"` need a
thread-specific external time source before inference. The system clock
remains the default production provider.
## Validation
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server --test all

Stacked on #28824.
## Summary
Codex Apps needs app-server as the source of truth for chat-started
background terminals instead of guessing from local process trees.
This PR adds experimental v2 APIs to list and terminate background
terminals for a loaded thread using app-server process ids, so clients
can manage background terminals without local PID discovery.
## Changes
- `thread/backgroundTerminals/list` returns paginated background
terminal records with `itemId`, app-server `processId`, `command`,
`cwd`, nullable `osPid`, nullable `cpuPercent`, and nullable `rssKb`.
- `thread/backgroundTerminals/terminate` terminates one running
background terminal by app-server `processId` and returns whether a
process was terminated.
- Background terminal list and terminate operations use unified-exec
process manager state as their source of truth.
## What
Exposes the pairing status transport as experimental app-server v2 RPC
`remoteControl/pairing/status`.
- Adds request/response protocol types for exactly one lookup key:
`pairingCode` or `manualPairingCode`, returning `{ claimed }`.
- Registers the RPC with `global_shared_read("remote-control-pairing")`.
- Wires the method through `MessageProcessor` and
`RemoteControlRequestProcessor`.
- Validates missing/conflicting pairing-code params as invalid requests.
- Documents the RPC in `app-server/README.md`.
- Adds processor, protocol export, and JSON-RPC integration coverage for
both code paths.
## Why
This is the app-server surface the desktop app can poll while the
QR/manual pairing modal is active.
Depends on https://github.com/openai/codex/pull/26449
Related backend change: https://github.com/openai/openai/pull/990244
## Verification
- `cargo test --manifest-path app-server-protocol/Cargo.toml
remote_control`
- `cargo test --manifest-path app-server/Cargo.toml remote_control`
- `cargo fmt --all --check`
- `git diff --check`
## Why
Remote-control clients need to list and revoke controller-device grants
without enabling or enrolling the local relay. These are signed-in
account-management operations, so coupling them to websocket, pairing,
enrollment, or persisted relay state would prevent clients from managing
stale grants from the picker.
Related enhancement request: N/A. This adds the Codex app-server surface
for the planned upstream environment-scoped revoke endpoint.
## What Changed
- Added experimental app-server v2 RPCs:
- `remoteControl/client/list`
- `remoteControl/client/revoke`
- Added picker-oriented protocol types and standard generated schema
fixtures. The list response intentionally omits backend account id,
enrollment status, and location fields.
- Added `app-server-transport/src/transport/remote_control/clients.rs`
for environment-scoped GET and DELETE requests. It builds escaped URL
path segments, forwards optional pagination query fields, sends ChatGPT
auth plus `chatgpt-account-id`, converts RFC3339 `last_seen_at` values
to Unix seconds, accepts `204 No Content` revoke responses, and retries
once after a `401`.
- Extracted shared ChatGPT auth loading and recovery into
`app-server-transport/src/transport/remote_control/auth.rs` so
websocket, pairing, and client management use the same account-auth
boundary.
- Retained the configured remote-control base URL on
`RemoteControlHandle` and resolve management URLs lazily, preserving
deferred validation while relay startup is disabled.
- Registered list as `global_shared_read("remote-control-clients")` and
revoke as `global("remote-control-clients")`.
## Verification
- Added transport coverage proving list and revoke work while relay
state is disabled, IDs are escaped, picker-only fields are returned,
timestamps are converted, revoke accepts `204`, auth headers are
forwarded, `401` retries exactly once, `403` is not retried, and
malformed list payloads retain decode context.
- Added an app-server integration test proving both JSON-RPC methods
work before relay enablement and successful revoke returns `{}`.
- Regenerated and validated experimental and standard app-server schema
fixtures.
## Why
Remote control enrollment authorizes a desktop server, but app-server v2
did not expose the follow-up pairing operation needed to mint a
short-lived controller pairing artifact from that enrolled server.
Clients need a narrow RPC that starts pairing without exposing the
backend `serverId` or conflating pairing with websocket connection
state.
Issue: N/A; internal remote-control pairing API change.
## What Changed
Added experimental app-server v2 `remoteControl/pairing/start` with
`manualCode` input and `pairingCode`, nullable `manualPairingCode`,
`environmentId`, and Unix-seconds `expiresAt` output. The method
serializes under its own `global("remote-control-pairing")` scope and is
documented in `app-server/README.md`.
Extended the remote-control transport with private `/server/pair`
request/response types and normalized `pair_url` handling. Pairing uses
the current enrolled server bearer, refreshes that bearer when needed,
keeps backend `server_id` private, validates returned `server_id` and
`environment_id` against the current enrollment, and preserves backend
status/header/body context for failures and malformed responses.
Wired the request through `RemoteControlRequestProcessor` and
`MessageProcessor`, mapping unavailable/disabled pairing to
`invalid_request` and backend failures to internal errors.
## Verification
- `just test -p codex-app-server-transport`
- `just test -p codex-app-server
remote_control_pairing_start_returns_pairing_artifacts`
## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.
## 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`

## 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.
## 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`

## Why
`argument-comment-lint` was green in CI even though the repo still had
many uncommented literal arguments. The main gap was target coverage:
the repo wrapper did not force Cargo to inspect test-only call sites, so
examples like the `latest_session_lookup_params(true, ...)` tests in
`codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.
This change cleans up the existing backlog, makes the default repo lint
path cover all Cargo targets, and starts rolling that stricter CI
enforcement out on the platform where it is currently validated.
## What changed
- mechanically fixed existing `argument-comment-lint` violations across
the `codex-rs` workspace, including tests, examples, and benches
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
`tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
`--all-targets` unless the caller explicitly narrows the target set
- fixed both wrappers so forwarded cargo arguments after `--` are
preserved with a single separator
- documented the new default behavior in
`tools/argument-comment-lint/README.md`
- updated `rust-ci` so the macOS lint lane keeps the plain wrapper
invocation and therefore enforces `--all-targets`, while Linux and
Windows temporarily pass `-- --lib --bins`
That temporary CI split keeps the stricter all-targets check where it is
already cleaned up, while leaving room to finish the remaining Linux-
and Windows-specific target-gated cleanup before enabling
`--all-targets` on those runners. The Linux and Windows failures on the
intermediate revision were caused by the wrapper forwarding bug, not by
additional lint findings in those lanes.
## Validation
- `bash -n tools/argument-comment-lint/run.sh`
- `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
- shell-level wrapper forwarding check for `-- --lib --bins`
- shell-level wrapper forwarding check for `-- --tests`
- `just argument-comment-lint`
- `cargo test` in `tools/argument-comment-lint`
- `cargo test -p codex-terminal-detection`
## Follow-up
- Clean up remaining Linux-only target-gated callsites, then switch the
Linux lint lane back to the plain wrapper invocation.
- Clean up remaining Windows-only target-gated callsites, then switch
the Windows lint lane back to the plain wrapper invocation.
## Why
This is effectively a follow-up to
[#15812](https://github.com/openai/codex/pull/15812). That change
removed the special skill-script exec path, but `skill_metadata` was
still being threaded through command-approval payloads even though the
approval flow no longer uses it to render prompts or resolve decisions.
Keeping it around added extra protocol, schema, and client surface area
without changing behavior.
Removing it keeps the command-approval contract smaller and avoids
carrying a dead field through app-server, TUI, and MCP boundaries.
## What changed
- removed `ExecApprovalRequestSkillMetadata` and the corresponding
`skillMetadata` field from core approval events and the v2 app-server
protocol
- removed the generated JSON and TypeScript schema output for that field
- updated app-server, MCP server, TUI, and TUI app-server approval
plumbing to stop forwarding the field
- cleaned up tests that previously constructed or asserted
`skillMetadata`
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-test-client`
- `cargo test -p codex-mcp-server`
- `just argument-comment-lint`
### Why
i'm working on something that parses and analyzes codex rollout logs,
and i'd like to have a schema for generating a parser/validator.
`codex app-server generate-internal-json-schema` writes an
`RolloutLine.json` file
while doing this, i noticed we have a writer <> reader mismatch issue on
`FunctionCallOutputPayload` and reasoning item ID -- added some schemars
annotations to fix those
### Test
```
$ just codex app-server generate-internal-json-schema --out ./foo
```
generates an `RolloutLine.json` file, which i validated against jsonl
files on disk
`just codex app-server --help` doesn't expose the
`generate-internal-json-schema` option by default, but you can do `just
codex app-server generate-internal-json-schema --help` if you know the
command
everything else still works

## Why
Once the repo-local lint exists, `codex-rs` needs to follow the
checked-in convention and CI needs to keep it from drifting. This commit
applies the fallback `/*param*/` style consistently across existing
positional literal call sites without changing those APIs.
The longer-term preference is still to avoid APIs that require comments
by choosing clearer parameter types and call shapes. This PR is
intentionally the mechanical follow-through for the places where the
existing signatures stay in place.
After rebasing onto newer `main`, the rollout also had to cover newly
introduced `tui_app_server` call sites. That made it clear the first cut
of the CI job was too expensive for the common path: it was spending
almost as much time installing `cargo-dylint` and re-testing the lint
crate as a representative test job spends running product tests. The CI
update keeps the full workspace enforcement but trims that extra
overhead from ordinary `codex-rs` PRs.
## What changed
- keep a dedicated `argument_comment_lint` job in `rust-ci`
- mechanically annotate remaining opaque positional literals across
`codex-rs` with exact `/*param*/` comments, including the rebased
`tui_app_server` call sites that now fall under the lint
- keep the checked-in style aligned with the lint policy by using
`/*param*/` and leaving string and char literals uncommented
- cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
registry/git metadata in the lint job
- split changed-path detection so the lint crate's own `cargo test` step
runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
- continue to run the repo wrapper over the `codex-rs` workspace, so
product-code enforcement is unchanged
Most of the code changes in this commit are intentionally mechanical
comment rewrites or insertions driven by the lint itself.
## Verification
- `./tools/argument-comment-lint/run.sh --workspace`
- `cargo test -p codex-tui-app-server -p codex-tui`
- parsed `.github/workflows/rust-ci.yml` locally with PyYAML

## What changed
- TypeScript schema fixture generation now goes through in-memory tree
helpers rather than a heavier on-disk generation path.
- The comparison logic normalizes generated banner and path differences
that are not semantically relevant to the exported schema.
- TypeScript and JSON fixture coverage are split into separate tests,
and the expensive schema-export tests are serialized in `nextest`.
## Why this fixes the flake
- The original fixture coverage mixed several heavy codegen paths into
one monolithic test and then compared generated output that included
incidental banner/path differences.
- On Windows CI, that combination created both runtime pressure and
output variance unrelated to the schema shapes we actually care about.
- Splitting the coverage isolates failures by format, in-memory
generation reduces filesystem churn, normalization strips generator
noise, and serializing the heavy tests removes parallel resource
contention.
## Scope
- Production helper change plus test changes.
This fixes a schema export bug where two different `WebSearchAction`
types were getting merged under the same name in the app-server v2 JSON
schema bundle.
The problem was that v2 thread items use the app-server API's
`WebSearchAction` with camelCase variants like `openPage`, while
`ThreadResumeParams.history` and
`RawResponseItemCompletedNotification.item` pull in the upstream
`ResponseItem` graph, which uses the Responses API snake_case shape like
`open_page`. During bundle generation we were flattening nested
definitions into the v2 namespace by plain name, so the later definition
could silently overwrite the earlier one.
That meant clients generating code from the bundled schema could end up
with the wrong `WebSearchAction` definition for v2 thread history. In
practice this shows up on web search items reconstructed from rollout
files with persisted extended history.
This change does two things:
- Gives the upstream Responses API schema a distinct JSON schema name:
`ResponsesApiWebSearchAction`
- Makes namespace-level schema definition collisions fail loudly instead
of silently overwriting
Realized EventMsg generated types were unintentionally removed as part
of this PR: https://github.com/openai/codex/pull/13375
Turns out our TypeScript export pipeline relied on transitively reaching
`EventMsg`. We should still export `EventMsg` explicitly since we're
still emitting `codex/event/*` events (for now, but getting dropped soon
as well).
## Summary
This removes the old app-server v1 methods and notifications we no
longer need, while keeping the small set the main codex app client still
depends on for now.
The remaining legacy surface is:
- `initialize`
- `getConversationSummary`
- `getAuthStatus`
- `gitDiffToRemote`
- `fuzzyFileSearch`
- `fuzzyFileSearch/sessionStart`
- `fuzzyFileSearch/sessionUpdate`
- `fuzzyFileSearch/sessionStop`
And the raw `codex/event/*` notifications emitted from core. These
notifications will be removed in a followup PR.
## What changed
- removed deprecated v1 request variants from the protocol and
app-server dispatcher
- removed deprecated typed notifications: `authStatusChange`,
`loginChatGptComplete`, and `sessionConfigured`
- updated the app-server test client to use v2 flows instead of deleted
v1 flows
- deleted legacy-only app-server test suites and added focused coverage
for `getConversationSummary`
- regenerated app-server schema fixtures and updated the MCP interface
docs to match the remaining compatibility surface
## Testing
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server`
## Summary
- add an `--experimental` flag to the export binary and thread the
option through TypeScript and JSON schema generation
- flatten the v2 schema bundle into a datamodel-code-generator-friendly
`codex_app_server_protocol.v2.schemas.json` export
- retarget shared helper refs to namespaced v2 definitions, add coverage
for the new export behavior, and vendor the generated schema fixtures
## Validation
- `cargo test -p codex-app-server-protocol` (71 unit tests and bin
targets passed locally; the final schema fixture integration target was
revalidated via fresh schema regeneration and a tree diff)
- `./target/debug/write_schema_fixtures --schema-root <tmpdir>`
- `diff -rq app-server-protocol/schema <tmpdir>`
