## Summary
- read the request-scoped safety-buffering treatment from HTTP response
headers and per-turn WebSocket metadata through one shared header parser
- combine that treatment with Responses API safety-buffering signals
- propagate `showBufferingUi` and nullable `fasterModel` through the
existing `model/safetyBuffering/updated` app-server notification
- update the app-server documentation and generated JSON and TypeScript
schemas
The public implementation contains no model mapping or real model
identifier. Tests and protocol examples use generic `current-model` and
`faster-model` placeholders only.
## Dependencies
- server-side treatment evaluation:
https://github.com/openai/openai/pull/1060247
- initial Responses API safety-buffering propagation:
https://github.com/openai/codex/pull/29371
- Codex App UI: https://github.com/openai/openai/pull/1057789
## Validation
- Codex API tests: 129 passed
- focused Codex core safety-buffering integration test passed
- app-server protocol tests passed after regenerating schema fixtures
- Clippy fix and repository formatting completed successfully
The broader app-server run compiled all changed crates and completed
with 1,269 passing tests. Its remaining failures were unrelated
environment limitations: macOS sandbox application was denied, one
expected test binary was unavailable, and several existing subprocess
tests timed out as a result.
## Stack
Stacked on #29417. Review and land that PR first.
## Summary
- reject HTTP(S) image URLs in the handlers for `turn/start` and
`turn/steer`
- validate `thread/inject_items` after its existing
JSON-to-`ResponseItem` conversion, so each item is deserialized once
- turn invalid dynamic-tool image responses into the existing
unsuccessful text fallback; the model receives the validation message as
the function output
- leave `thread/resume.history` compatible with legacy history; #29417
replaces remote images before model input
- continue accepting inline data URLs and `localImage` inputs
- keep this policy in app-server; this PR does not add a shared protocol
API or change core image preparation
## Test plan
- `just test -p codex-app-server -E
'test(/request_handlers_reject_remote_image_urls|dynamic_tool_remote_image_response_becomes_model_visible_error|dynamic_tool_call_round_trip_sends_content_items_to_model|turn_start_tracks_turn_event_analytics|standalone_image_edit_uses_recent_pathless_image/)'`
(5 passed)
- `just fix -p codex-app-server`
- `just fmt`
## Why
`permissionProfile/list` currently advertises every built-in and
configured profile even when effective enterprise requirements prevent
selecting it. That forces each client to reconstruct policy from
lower-level requirement fields, which is easy to miss and difficult to
keep consistent.
The catalog should remain complete so clients can explain that an option
was disabled by an administrator, while also reporting whether each
profile is selectable.
## What
- Add an `allowed` field to each permission profile summary.
- Build a shared catalog from the effective config and current
requirements, including `allowed_sandbox_modes`, `allowed_permissions`,
and filesystem restrictions.
- Use the shared catalog in app-server and the TUI so disallowed
profiles remain visible but cannot be selected.
- Use the canonical `:danger-full-access` profile ID in the TUI.
- Update the app-server schemas, API documentation, behavioral tests,
and TUI snapshots.
## Scope
This PR targets `main` directly and is independent of #24852. It
preserves the current behavior where built-in profiles are constrained
by sandbox-mode requirements and `allowed_permissions` applies to
configured profiles.
## Testing
- `just test -p codex-core

# Summary
Codex required every ChatGPT account to have an email address. A
service-account personal access token can return valid account metadata
without one, so PAT login failed while decoding the metadata response.
This change makes email optional in the account metadata type that owns
it and preserves that absence through authentication, provider account
state, the app-server API, generated clients, and TUI bootstrap.
Existing accounts with email addresses keep the same behavior.
## Behavior-changing call sites
| Call site | Behavior after this change |
| --- | --- |
| `login/src/auth/personal_access_token.rs` | PAT metadata accepts a
missing or null email and retains `None`. |
| `agent-identity/src/lib.rs` | Agent Identity JWT claims accept an
omitted email. |
| `login/src/auth/storage.rs` and `login/src/auth/agent_identity.rs` |
Stored and managed Agent Identity records carry `Option<String>`.
Deserialization maps the legacy empty-string sentinel to `None`. |
| `login/src/auth/manager.rs` | `get_account_email` returns the stored
option, and managed identity bootstrap no longer converts `None` to an
empty string. |
| `model-provider/src/provider.rs` and `protocol/src/account.rs` | A
ChatGPT provider account requires a plan type but may carry no email. |
| `app-server-protocol/src/protocol/v2/account.rs` | `account/read`
keeps the `email` field on the wire and returns `null` when the account
has no email. Generated TypeScript and JSON schemas describe a required,
nullable field. |
| `sdk/python/src/openai_codex/generated/v2_all.py` | The generated
Python `ChatgptAccount` model accepts `None` for email. |
| `tui/src/app_server_session.rs` | Email-less ChatGPT accounts
bootstrap normally, keep external feedback routing, omit account-email
telemetry, and display the plan in account status. |
## Design decisions
- Missing email remains `None` at every layer. The code never uses an
empty string as a substitute.
- The app-server response includes `"email": null` instead of omitting
the field. Clients retain a stable response shape.
- Plan type remains required for provider account state. This change
relaxes only the email assumption.
## Testing
Tests: affected test targets compile, scoped Clippy and formatting pass,
a focused TUI snapshot covers plan-only account status, real
before/after PAT login smoke covers metadata without email, app-server
smoke covers `account/read` with `email: null`, and a regression smoke
covers an existing email-bearing PAT. Unit tests run in CI.
## Evidence
Visual smoke evidence will be attached here.
## Why
Multi-agent delegation policy was split across `multiAgentMode`,
`features.multi_agent_mode`, and `usage_hint_enabled`. These controls
could disagree: a requested mode could be downgraded by the feature
flag, and disabling usage hints also disabled mode instructions.
Some clients also need multi-agent tools without adding
delegation-policy text to model context. The previous two-mode API could
not express that directly.
## What changed
`multiAgentMode` is now the only live delegation-policy control:
| Mode | Behavior |
| --- | --- |
| `none` | Keep multi-agent tools available without adding mode
instructions. |
| `explicitRequestOnly` | Only delegate after an explicit user request.
|
| `proactive` | Delegate when parallel work materially improves speed or
quality. |
- new threads default to `explicitRequestOnly`; omitting the mode on
later turns keeps the current value
- thread start, resume, fork, and settings responses always report the
concrete current mode instead of `null`
- mode selection remains sticky across turns and resume
- usage-hint text no longer controls whether mode instructions apply
- `features.multi_agent_mode` and `usage_hint_enabled` remain accepted
as ignored compatibility settings so existing configs continue to load
- app-server documentation and generated schemas describe the three-mode
API
## Tests
- `just test -p codex-core multi_agent_mode`
- `just test -p codex-core multi_agent_v2_config_from_feature_table`
- `just test -p codex-core spawn_agent_description`
- `just test -p codex-features`
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server multi_agent_mode`
Responses API safety buffering metadata currently stops at the transport
boundary, so app-server clients cannot render the in-progress safety
review state.
This change:
- decodes and deduplicates `safety_buffering` metadata from Responses
API SSE and WebSocket events without suppressing the original response
event
- emits a typed core event containing the requested model plus backend
use cases and reasons
- forwards that event as `turn/safetyBuffering/updated` through
app-server v2 and updates generated protocol schemas
- keeps the side-channel event out of persisted rollouts and turn timing
This supports the Codex Apps buffering UX and depends on the Responses
API backend work in https://github.com/openai/openai/pull/1044569 and
https://github.com/openai/openai/pull/1044571.
Validation:
- focused `codex-core` safety-buffering integration test passes
- `cargo check -p codex-core -p codex-app-server -p
codex-app-server-protocol`
- `just fix -p codex-api -p codex-protocol -p codex-core -p
codex-app-server-protocol -p codex-app-server -p codex-rollout -p
codex-rollout-trace -p codex-otel`
- `just fmt`
- broad package test run: 4,430/4,492 passed; 62 unrelated
local-environment/concurrency failures involved unavailable test
binaries, MCP subprocess setup, and app-server timeouts
## Why
Once multi-agent mode can be selected per turn, clients also need to
choose the initial selection when creating a thread and observe that
selection through lifecycle and settings APIs.
The selected value is intentionally distinct from the effective
model-visible value: no client selection is represented as `null`, even
though an eligible multi-agent v2 turn derives `explicitRequestOnly` as
its effective default.
## What changed
- Add the optional experimental `thread/start.multiAgentMode` parameter
and pass it through thread creation.
- Preserve an omitted initial value as an unset selection rather than
eagerly storing `explicitRequestOnly`.
- Apply an explicit `thread/start` selection to the first turn through
the session configuration established at thread creation.
- Restore the latest persisted effective mode as the selected baseline
on cold resume when rollout history contains one.
- Inherit the optional selected mode from a loaded parent when creating
related runtime threads.
- Return the current selected `multiAgentMode` from `thread/start`,
`thread/resume`, `thread/fork`, and thread settings, using `null` when
no mode is selected.
- Keep lifecycle reporting independent from model capability and feature
eligibility; core turn construction remains responsible for calculating
and persisting the effective mode.
## Not covered
- Clearing an existing loaded-session selection back to unset through
`turn/start`; omitted or `null` currently retains the session's
selection.
- A TUI control, slash command, or `config.toml` preference.
## Verification
- `CARGO_INCREMENTAL=0 just test -p codex-app-server-protocol`
- `CARGO_INCREMENTAL=0 just test -p codex-app-server multi_agent_mode`
The focused app-server coverage verifies explicit `thread/start`
initialization, first-turn prompting, nullable reporting for an omitted
selection, and retention of selections that are not currently
runtime-eligible.
## Stack
Stacked on #28685. This PR contains only the thread initialization and
lifecycle/settings API layer.
## Why
Multi-agent v2 currently carries an explicit-request-only delegation
rule in its static usage hint. That provides a safe default, but it
prevents clients from selecting proactive delegation per turn without
changing static guidance or rewriting prior model context.
This change makes delegation mode a session selection that can be
updated through `turn/start`, while deriving the effective model-visible
mode separately for each turn. Eligible multi-agent v2 turns remain
explicit-request-only unless proactive mode is both selected and
enabled.
## What changed
- Add the experimental `turn/start.multiAgentMode` parameter with
`explicitRequestOnly` and `proactive` values. Omission retains the
loaded session's current optional selection.
- Add the default-off `features.multi_agent_mode` feature gate. Eligible
multi-agent v2 turns use the selected mode when enabled; an unset
selection or disabled gate resolves to `explicitRequestOnly`.
- Treat mode prompting as inapplicable for multi-agent v1 and other
unsupported session configurations, producing no multi-agent mode
developer message rather than rejecting the turn.
- Move the explicit-request-only rule out of the static v2 usage hint
and into a bounded, tagged developer context fragment.
- Emit the effective mode in initial context and only when that
effective mode changes on later turns.
- Persist the effective mode in `TurnContextItem` as the durable
baseline for resume and context-update comparisons.
Historical rollout items are not rewritten. Later mode developer
messages establish the current rule incrementally.
## Not covered
- Initial selection through `thread/start` and selected-mode reporting
from thread lifecycle/settings APIs; those are isolated in the stacked
#28792.
- A TUI control or slash command for selecting the mode.
- Persisting a preferred mode to `config.toml`; selection remains
session/turn scoped.
- Changes to multi-agent concurrency limits, tool availability, or model
catalog capability declarations.
- Rewriting historical rollout prompt items. Cold resume restores the
latest persisted effective mode when available while leaving historical
developer messages intact.
## Verification
- `CARGO_INCREMENTAL=0 just test -p codex-core multi_agent_mode`
- Focused app-server coverage verifies that `turn/start.multiAgentMode`
produces proactive developer instructions for an eligible v2 turn.
## Stack
Followed by #28792, which adds `thread/start` initialization and
lifecycle/settings observability.
## Why
Remote environments registered through `environment/add` currently use
the fixed 10-second WebSocket connection timeout. Slow-starting
executors need a caller-selected connection window, but this should not
add retry policy or couple exec-server behavior to Core’s
`deferred_executor` feature.
Make the timeout an optional part of the existing experimental request.
Existing clients continue using the current default, while callers that
know an executor may take longer can request a larger window explicitly.
Depends on #28683.
## What changed
- Add optional `connectTimeoutMs` to `EnvironmentAddParams` and document
it in the app-server README.
- Pass the optional timeout through `EnvironmentRequestProcessor` into
one `EnvironmentManager::upsert_environment()` path; the manager applies
the existing default when it is omitted.
- Preserve the existing single-attempt lifecycle. The configured value
controls WebSocket connection and handshake time for both initial
connection and later reconnects; initialization retains its separate
timeout.
- Add an app-server integration test that sends the real JSON-RPC
request and verifies a stalled handshake observes the requested timeout.
## Test plan
- `just test -p codex-app-server-protocol`
- `just test -p codex-exec-server`
- `just test -p codex-app-server
environment_add_applies_connect_timeout`
## Rollout
This is additive and does not enable `deferred_executor`. Callers should
send a non-default timeout only after a compatible app-server is
deployed; omitted or `null` values retain the existing 10-second
default.
## Summary
- Remove the realtime `architecture` selector from core protocol,
app-server protocol, config parsing, generated schemas, and callers.
- Always create WebRTC realtime calls with the AVAS query params:
`intent=quicksilver&architecture=avas`.
- Keep direct websocket realtime behavior on the existing config/default
path, while WebRTC starts without an explicit version now default to
realtime v1 because AVAS requires v1.
## Notes
- WebRTC realtime now means AVAS. If a caller explicitly asks to start
WebRTC with realtime v2, Codex rejects that request because the AVAS
WebRTC path only supports realtime v1. Websocket realtime is separate
and can still use realtime v2.
- The old `[realtime] architecture = "realtimeapi" | "avas"` config knob
is removed. Local configs that still set it will need to delete that
line.
- Some app-server tests that were only trying to exercise realtime v2
protocol behavior now use websocket transport, because WebRTC is
intentionally locked to AVAS/v1. Separate WebRTC tests cover the AVAS
query params, v1 startup, SDP flow, and sideband join.
## Validation

## Why
Make it possible to load AGENTS.md from remote exec-servers whose OS is
different than app-server.
## What
- keep `AGENTS.md` discovery and provenance as `PathUri`, with
root-aware parent and ancestor traversal
- expose lifecycle instruction sources as legacy app-server path strings
in events while retaining `PathUri` internally
- preserve and test mixed POSIX and Windows paths in model context and
TUI status output
- cover remote Windows loading end to end by seeding the Wine prefix
through host filesystem APIs
- fix bug in `PathUri`'s parent() implementation that would erase
Windows drive letters
## 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.

Stacked on #28824.
## Why
Frontend realtime voice continuity needs to replay a tiny
previous-session overlap as actual conversation items, including
assistant text. The app-server `thread/realtime/appendText` API already
carries a role through to the Rust realtime websocket layer, but the
shared role enum only accepted `user` and `developer`.
## What Changed
- Added `assistant` to `ConversationTextRole` and regenerated the
app-server schema/type fixtures.
- Added `output_text` as a realtime conversation content type.
- Updated realtime websocket item creation so assistant appendText emits
`content: [{ type: "output_text", text }]`, while user and developer
continue to emit `input_text`.
- Updated app-server docs and tests to cover assistant appendText
alongside the existing developer role behavior.
## Validation
- `just write-app-server-schema`
- `just fmt` (first sandboxed attempt failed because `uv` could not
access `~/.cache/uv`; reran with filesystem access and passed)
- `just test -p codex-api` passed: 126/126
- `just test -p codex-app-server-protocol` passed: 239/239, including
generated JSON/TypeScript fixture checks
- `just test -p codex-app-server` was started locally but stopped per
request after unrelated local sandbox/Seatbelt failures (`sandbox-exec:
sandbox_apply: Operation not permitted`) and one missing local `codex`
binary failure; CI should be faster and more authoritative for the full
suite.
## What
Built on the realtime speech-control plumbing merged in #27917.
- Add optional `codexResponseHandoffPrefix` to `thread/realtime/start`.
- Apply that prefix only to automatic V1 commentary sent through
`conversation.handoff.append`; final answers remain unprefixed.
- Add opt-in `clientManagedHandoffs`. When true, core suppresses
automatic response handoffs and completion output so delivery is
controlled by explicit client append APIs.
- Preserve existing automatic behavior by default.
`codexResponsesAsItems: true` continues to select item routing when
client-managed mode is disabled.
## Why
Voice clients need two delivery policies: automatic background context
with silent commentary instructions and fully client-owned handoffs.
Phase-aware prefixing keeps routine commentary silent without
suppressing the final answer, while client-managed mode lets an app
decide exactly which updates to append.
## Validation
- `just fmt`
- `cargo test -p codex-app-server-protocol

- `RUST_MIN_STACK=16777216 cargo test -p codex-core --test all

- `cargo build -p codex-cli --bin codex`
- Local Codex Apps compatibility check: 43 focused webview tests passed,
and a live voice session routed through the source-built app-server.
The explicit `RUST_MIN_STACK` avoids a macOS Tokio test-worker stack
overflow seen with the default test environment.
## Summary
- Track plugin install failures through the unified
`codex_plugin_install_failed` event for local installs, remote install
preflight failures, bundle failures, and remote catalog/backend
failures.
- Send classified `error_type` values in plugin install failure
analytics instead of raw error strings.
- Stop sending raw external-agent import errors in analytics while
preserving raw failure details in app-facing import
notifications/history.
- Keep raw plugin/migration diagnostics in `tracing::warn!` logs.
- Keep remote failure plugin names as the existing local placeholder
(`unknown`) and remove the extra telemetry plugin-name override.
- Change `ExternalAgentConfigImportParams.source` from a generated enum
to `string | null`, with legacy `claudeCode` / `claudeCowork` inputs
normalized to existing analytics values.
## Testing
## Summary
- Revert #28655, restoring the thread `recencyAt` behavior introduced by
#27910.
- Move `threads_recency_at` to migration 0039 so it no longer collides
with `external_agent_config_imports` at version 0038.
- Repair databases that already applied the recency migration as version
38 by moving the matching migration-history row to version 39 before
SQLx validation. The current version-38 migration can then apply
normally.
## Validation
- `just test -p codex-state
migrations::tests::repairs_recency_migration_that_was_applied_as_version_38`
- `just test -p codex-state -p codex-rollout -p codex-thread-store -p
codex-app-server-protocol -p codex-tui`: 3,439 passed; six TUI tests
could not open the machine's existing read-only incident database at
`~/.codex/sqlite/state_5.sqlite`.
- `just fix -p codex-state`
- `just fmt`
- Verified that state migration versions are unique.
## Why
Command approval cache keys included the command and working directory,
but not the execution environment. An approval for `/workspace` locally
could therefore be reused for the same command and path on an executor.
## What changed
- Include the selected environment ID in shell and unified-exec approval
cache keys.
- Carry that ID through the normal command approval request so clients
can show which environment is being approved.
- Expose the environment through app-server as a required nullable
`environmentId` and show it in the inline TUI approval prompt.
- Keep older recorded approval events compatible when the environment is
absent.
For example, `echo ok` in local `/workspace` and `echo ok` in executor
`/workspace` now produce different approval keys and separate prompts.
## Scope
This PR does not change network approvals, Guardian review actions, MCP
elicitation, full-screen TUI rendering, or environment-ID validation.
Remote `shell_command` execution itself remains in #28722; this PR only
makes its approval key environment-aware.
## Why
Revert #27910 to remove the newly introduced thread `recencyAt`
persistence and API behavior from `main`.
## What changed
This reverts commit `fac3158c2a783095768076489815f361fa9b0db4`,
including the state migration, thread-store propagation, app-server API
surface, generated schemas, and related tests.
## Validation
Not run before opening; relying on CI for the initial fast signal.
## Summary
Add a server-owned `recencyAt` timestamp and `recency_at` thread-list
sort key for product recency ordering while preserving the existing
meaning of `updatedAt` as the latest persisted thread mutation.
This is the server-side alternative to #27697. Rather than narrowing
`updatedAt`, clients can sort the sidebar by `recency_at` and continue
treating `updatedAt` as mutation time.
Paired Codex Apps PR:
[openai/openai#1024599](https://github.com/openai/openai/pull/1024599)
## Contract
- `recencyAt` initializes when a thread is created.
- A turn start advances `recencyAt` monotonically.
- Commentary, agent output, tool results, token/accounting updates, turn
completion, archive, unarchive, resume, and generic metadata writes do
not advance it.
- `updatedAt` retains its existing behavior and continues to advance for
persisted thread mutations.
- Current servers populate `recencyAt`; the response field is optional
in generated TypeScript so clients connected to older servers can fall
back to `updatedAt`.
- Filesystem-only fallback uses existing updated/mtime ordering when
SQLite is unavailable.
## Persistence and compatibility
Migration 0038 adds second- and millisecond-precision recency columns,
backfills them from the existing updated timestamp, creates list
indexes, and includes an insert trigger so older binaries writing to a
migrated database seed recency without causing later mutations to
advance it.
Generic metadata upserts preserve existing recency values. Turn-start
updates use a dedicated monotonic touch, and process-local allocation
keeps millisecond cursor values unique. State DB list, search, read,
filtered-list repair, rollout fallback propagation, and app-server
conversions all carry the new field.
## API
`Thread` responses include:
```ts
recencyAt?: number
```
`thread/list` and `thread/search` accept:
```json
{ "sortKey": "recency_at" }
```
Generated TypeScript and JSON schemas are included.

## Why
`account/read` currently reports only `type: "amazonBedrock"`, so
clients cannot distinguish a Codex-managed Bedrock API key from
credentials supplied by AWS. The app UI needs that distinction to render
the appropriate account state without duplicating provider-auth logic.
Credential-source selection belongs to the Bedrock model provider
because it already owns the precedence between managed Bedrock auth and
the external AWS credential path. This builds on #27443 and #27689.
## What changed
- Added `AmazonBedrockCredentialSource` with `codexManaged` and
`awsManaged` values.
- Included the selected credential source in
`ProviderAccount::AmazonBedrock` and the app-server `Account` response.
- Made `AmazonBedrockModelProvider::account_state()` classify the source
from its managed-auth state.
- Regenerated the app-server JSON and TypeScript schemas.
- Updated app-server account documentation and downstream TUI matches.
`codexManaged` means the provider found a managed Bedrock API key.
`awsManaged` identifies the provider's external AWS credential path; it
does not assert that the AWS credential chain has been validated.
## Testing
- Added model-provider coverage for Codex-managed precedence and
AWS-managed fallback.
- Added app-server protocol serialization coverage for both wire values.
- Added app-server integration coverage for both `account/read`
responses.
- `just test -p codex-protocol -p codex-model-provider -p
codex-app-server-protocol` (497 tests passed).
After rebasing onto #27711, the `codex-app-server` test target compiled
past the image-generation `PathUri` migration. Local linking was then
interrupted by disk exhaustion (`No space left on device`).
## Why
Models sometimes need to pause briefly while waiting for external work,
but using a shell command for that delay ties the wait to a process and
does not naturally resume when new turn input arrives.
## What changed
- add a built-in `sleep` tool behind the under-development `sleep_tool`
feature
- accept a bounded `duration_ms` argument, matching the millisecond
convention used by unified exec
- end the sleep early when either steered user input or mailbox input
arrives
- include elapsed wall-clock time in completed and interrupted outputs
- emit a dedicated core `SleepItem` through `item/started` and
`item/completed`
- expose the sleep item as app-server v2 `ThreadItem::Sleep` and retain
it in reconstructed thread history
- regenerate the configuration schema for the new feature flag
- regenerate app-server JSON and TypeScript schema fixtures
## Test plan

- Add `includeStartupContext` to realtime start requests so callers can
explicitly skip Codex startup context while keeping the backend prompt
- Thread the new flag through protocol types, request processing, and
realtime session config
- Update app-server docs and coverage for the new default and opt-out
behavior
## Testing
- Added protocol serialization coverage for `includeStartupContext`
- Added realtime integration coverage for starting a session with
startup context disabled
## Why
Realtime voice harness tuning needs app-side control over what backend
Codex text is spoken. Backend orchestrator text is written for a reading
UI, so automatically speaking every preamble, progress update, or final
assistant message can make the realtime voice model too chatty.
For experimentation, clients need two simple controls: keep app/client
text-item injection on the existing item-create path, and add an
explicit speakable path that app code can call only when it wants
realtime to speak. Automatic Codex output also needs an opt-in way to
switch from the protocol's default speakable path to regular realtime
items, with a caller-provided prefix so prompt wording can be tuned
outside core.
The default remains unchanged: if a client omits the new start fields
and never calls `appendSpeech`, automatic backend output continues down
the existing speakable path for the selected realtime protocol.
## What Changed
- Adds experimental `thread/realtime/appendSpeech` for app-provided
speakable text.
- Keeps existing `thread/realtime/appendText` as the item-create API for
app-provided realtime text items.
- Adds `codexResponsesAsItems` / `codex_responses_as_items` on
`thread/realtime/start` to send automatic Codex responses with
`conversation.item.create` instead of the protocol's default speakable
output path.
- Adds `codexResponseItemPrefix` / `codex_response_item_prefix` so
clients can prepend experiment instructions to those automatic Codex
response items.
- Keeps literal `conversation.handoff.append` routing scoped to the v1
speakable path; v2 default speech uses its item/function-output plus
`response.create` behavior.
- Removes the earlier public silent-context API and hardcoded
silent-context prefix.
- Updates realtime tests to cover default automatic speakable behavior,
opt-in automatic item-create behavior, and explicit `appendSpeech`
behavior.

## Summary
- add the `created-by-me-remote` marketplace backed by paginated
`scope=USER` plugin directory and installed-plugin requests
- include USER plugins in installed-plugin caching, bundle sync, and
stale-cache cleanup without client-side discoverability filtering
- expose the marketplace through app-server v2 and regenerate the
protocol schemas

## Why
Codex users can earn personal rate-limit reset credits, but app-server
clients do not currently have an API for reading or redeeming them. This
adds the backend and protocol foundation used by the `/usage` TUI flow
in #28154.
## What changed
- Extend `account/rateLimits/read` with a nullable
`rateLimitResetCredits` summary sourced from the existing usage
response.
- Add backend-client and app-server support for consuming a reset with a
caller-generated idempotency key. A UUID is recommended, and clients
reuse the same key when retrying the same logical reset.
- Return only the consume `outcome`; clients refetch
`account/rateLimits/read` for updated window state.
- Document the response field and each consume outcome, and regenerate
the JSON and TypeScript schema fixtures.
- Clarify in `AGENTS.md` that new app-server string enum values use
camelCase on the wire.
- Update the existing TUI response fixture for the expanded protocol
shape.
- Add coverage for authentication, response mapping, backend failures,
consume outcomes, and request timeout behavior.
## Validation
- `just test -p codex-app-server-protocol` — 231 passed.
- `just test -p codex-backend-client` — 14 passed.
- Focused `codex-app-server` reset-credit tests — 5 passed.
- Focused `codex-tui` protocol response fixture test — passed.
- `just fix -p codex-backend-client -p codex-app-server-protocol -p
codex-app-server` — passed.
- `just fmt` — passed.
## Why
External-agent imports can complete synchronously or continue in the
background for plugins/sessions. Clients need a stable import id to
correlate the immediate response with the eventual completion
notification, and the completion payload needs enough accounting to show
which artifact types succeeded or failed without hiding partial
failures.
## What Changed
- `externalAgentConfig/import` now returns an `importId`;
`externalAgentConfig/import/completed` includes the same `importId` plus
type-level `itemResults`.
- Completed `itemResults` report `successCount`, `errorCount`,
`successes`, and `rawErrors` for each migrated item type.
- Added protocol/schema/TypeScript types for import successes, raw
errors, and type-level results. No progress notification is included in
the final PR.
- `ExternalAgentConfigService::import` now returns an outcome object
with synchronous item results and pending plugin imports.
- Plugin import outcomes track succeeded/failed marketplaces, plugin
ids, and raw errors. Plugin failures can be reported in completed
accounting while later migration items continue.
- Non-plugin synchronous import failures still fail the request, so
invalid config/skills-style failures are not reported as a successful
import response.
- Session imports now return item results. Successful imports include
the source session path and imported thread id; prepare, persist,
ledger, and source-validation failures become raw errors in completion
accounting where the import can continue.
- The request processor generates the `importId`, aggregates synchronous
results with background plugin/session results, and sends a single
completed notification when all selected work is done.
- App-server docs and generated schema fixtures were updated for the new
response/completed payload shapes.

Stacked on #27365.
## Stack note
[#27365](https://github.com/openai/codex/pull/27365) kept `thread/start`
unchanged and converted its input in `thread_processor`. This PR updates
`thread/start` to accept explicit functions and namespaces directly.
Legacy per-tool arrays are still accepted and converted while reading
the request. As a result, `thread_processor` can validate and pass the
tools through directly, which is why some code added in #27365 is
removed here.
## Why
`thread/start.dynamicTools` still repeats namespace data on each
function even though core now stores explicit namespace groups. The
request API should use the same shape so each namespace has one
description and one member list.
## What changed
- Accept top-level functions and explicit namespace objects in
`dynamicTools`.
- Continue accepting fully legacy flat arrays, including
`exposeToContext`.
- Reject arrays that mix legacy and canonical entries.
- Reuse the protocol types directly and remove the temporary app-server
adapter.
- Update validation, docs, the test client, and generated schemas.

## Why
#27870 teaches the MCP extension how to discover stdio MCP servers
declared by a selected executor plugin, but app-server does not yet
install that contributor or initialize its per-thread state. As a
result, `thread/start.selectedCapabilityRoots` can select the plugin
while its MCP servers remain inactive.
This PR closes that app-server wiring gap:
```text
thread/start(selectedCapabilityRoots)
-> initialize the thread's selected-plugin MCP snapshot
-> read the selected plugin's .mcp.json through its environment
-> start declared stdio servers in that environment
-> expose their tools only on the selected thread
```
## What changed
- Install the selected-executor-plugin MCP contributor in app-server
using the existing shared `EnvironmentManager`.
- Initialize its frozen thread snapshot when `thread/start` includes
selected capability roots.
- Document that selected plugin stdio MCPs are activated in their owning
environment.
- Add an app-server E2E covering the complete selection-to-tool-call
path.
The E2E verifies that:
- the selected MCP process receives an executor-only environment value,
proving the tool runs through the selected environment;
- the MCP tool is advertised to the model and can be called;
- a normal MCP config reload does not discard the thread's frozen
selected-plugin registration;
- another thread without the selected root does not see the MCP server.
## Scope
- Existing sessions without `selectedCapabilityRoots` are unchanged.
- Only stdio MCP declarations are activated. HTTP declarations remain
inactive.
- This does not change selected-root persistence across resume/fork or
add hosted-plugin behavior.
## Verification
- Focused app-server E2E:
`selected_executor_plugin_exposes_its_stdio_mcp_only_to_that_thread`
## Stack
Stacked on #27870.
## Why
Clients that display or coordinate spawned subagents need an
authoritative snapshot of a thread's immediate spawned children when
they connect to app-server or recover after missing live events.
`thread/list` cannot query by parent, so clients must otherwise scan
unrelated threads or reconstruct relationships from rollout history and
transient events.
The direct spawn relationship already exists in persisted
`thread_spawn_edges` state. Review and Guardian threads do not
participate in that lifecycle and are intentionally outside this
filter's scope.
## What changed
This adds an experimental `parentThreadId` filter to `thread/list`.
Parent-filtered requests return direct spawned children from persisted
state while preserving the existing response shape, explicit filters,
sorting, and timestamp-only cursor behavior. The lookup does not read
rollout transcripts or recursively return descendants.
Supersedes #25112 with the narrower `thread/list` filter approach.
## How it works
1. An experimental client passes a valid thread ID as `parentThreadId`.
2. App-server routes the list through the existing thread-store and
state-database boundaries.
3. SQLite selects threads whose IDs have a direct persisted spawn edge
from that parent.
4. Omitted provider and source filters include all values; explicit
filters keep ordinary `thread/list` semantics.
5. Grandchildren, Review threads, and Guardian threads are excluded.
## Verification
State (144 tests), rollout (69 tests), and focused app-server
thread-list (31 tests) suites passed. Scoped Clippy checks and
repository formatting also passed. Coverage includes direct spawned
children, omitted grandchildren, pagination, malformed IDs, mixed source
kinds, explicit filters, and operation without rollout files.
## Why
Managed deployments need a reliable deny gate for remote control.
Persisted enablement and explicit startup requests currently remain able
to start the transport, while the removed `features.remote_control` key
is intentionally only a compatibility no-op.
This adds a dedicated requirement that administrators can use to force
remote control off without deleting the user's persisted preference.
Removing the requirement and restarting restores the prior choice.
## What Changed
- Added top-level `allow_remote_control` requirements parsing, sourced
layer precedence, debug output, and `configRequirements/read` exposure
as `allowRemoteControl`.
- Added a typed transport policy captured from the startup requirements
snapshot. Managed disable forces the initial state to disabled and
prevents enrollment, refresh, connection, and persisted-preference
mutation.
- Rejected every `remoteControl/*` RPC before parameter deserialization
with JSON-RPC `-32600` and `remote control is disabled by managed
requirements`.
- Preserved the existing disabled status notification and the previous
behavior when the requirement is `true` or omitted.
- Regenerated app-server protocol schemas and documented the new
requirement.
## Verification
- Confirmed all remote-control RPCs, including a malformed request,
return the managed-policy error while the initial status notification
remains `disabled`.
- Confirmed explicit ephemeral startup and persisted enablement make no
backend connection and leave the SQLite preference unchanged.
- Confirmed `allow_remote_control = true` does not enable or block
remote control and `configRequirements/read` returns
`allowRemoteControl: false` for the deny policy.
Related issue: N/A (managed-policy hardening).
## Summary
Add an explicit `user` or `developer` role to
`thread/realtime/appendText` and propagate it through the realtime input
queue into `conversation.item.create`. Older JSON clients that omit the
field continue to default to `user`.
This lets app-provided context such as memory retain developer authority
without bypassing app-server through a renderer-owned data channel. The
app-server schemas, API documentation, and focused protocol and
websocket coverage are updated with the new contract.
The Codex Apps consumer is tracked in
[openai/openai#1025261](https://github.com/openai/openai/pull/1025261).
## Summary
- expose the remote plugin detail endpoint's `share_url` as nullable
`PluginDetail.shareUrl`
- preserve existing `PluginSummary.shareContext` behavior for local and
workspace sharing flows
- regenerate the app-server TypeScript and JSON schema fixtures
## Why
The remote plugin detail response already includes a canonical
`share_url`, but that value was not surfaced by `plugin/read` for global
plugins. Global plugins intentionally have no `shareContext`, so using
that model for the URL would change the semantics consumed by the
existing share modal.
## User impact
Codex clients can use `PluginDetail.shareUrl` for a remote plugin's
copy-link action, including when the plugin is disabled by an
administrator, without changing existing share-modal or ownership
behavior.

## Summary
- add `approvals_reviewer` support to `[apps._default]`
- resolve connected-app reviewers in per-app, app-default, then global
order
- expose the setting through the v2 config API and regenerate schema
fixtures
## Context
PR #25167 added `apps.<connector_id>.approvals_reviewer`, but the shared
app defaults table could not specify the reviewer. This extends the same
behavior to `[apps._default]` while preserving per-app overrides.
Managed `allowed_approvals_reviewers` requirements still constrain both
default and per-app values. A disallowed app value falls back to the
global reviewer, and non-app MCP servers continue using the global
reviewer.

## Why
Remote-control runtime enablement and persisted enrollment preference
were represented by separate flags. That made startup rehydration, RPC
persistence, and new-enrollment seeding race with one another, and it
did not cleanly distinguish runtime-only CLI or daemon starts from
durable app-server RPC changes.
## What Changed
- Replace the parallel enablement, seed, and rehydration flags with one
transport-owned `RemoteControlDesiredState`.
- Add nullable enrollment-scoped persistence and preserve existing
preferences during enrollment upserts.
- Rehydrate plain startup only after auth and client scope resolve,
without overwriting a concurrent RPC transition.
- Make ordinary `remoteControl/enable` and `remoteControl/disable`
durable while retaining `ephemeral: true` for runtime-only callers.
- Have the daemon explicitly request ephemeral enablement and regenerate
the app-server schemas.
## Verification
- Covered migration and `NULL`/`0`/`1` persistence round trips.
- Covered plain-start rehydration and runtime-only versus durable
enrollment seeding.
- Covered durable enable, durable disable, and ephemeral enable through
app-server RPC.
- Covered the daemon's exact `{ "ephemeral": true }` request payload.
Related issue: N/A (internal remote-control persistence architecture
change).
## Summary
- remove the redundant `needsAuth` field from `AppSummary` and generated
app-server schemas
- stop `plugin/read` from querying Apps MCP solely to hydrate unused
connector auth state
- preserve `plugin/install.appsNeedingAuth` membership and
`app/list.isAccessible` as the authentication signals
## Why
Codex App and TUI do not consume `plugin/read.plugin.apps[].needsAuth`.
Hydrating it could establish an Apps MCP connection and discover tools
on a cold `plugin/read` request, adding avoidable latency. The plugin
APIs are still marked under development, so removing this wire field is
preferable to retaining a misleading default.

## Why
Clients can archive and unarchive threads today, but there is no
app-server API for permanently removing a thread. Deletion also needs to
cover the full session tree: deleting a main thread should remove
spawned subagent threads and the related local metadata instead of
leaving orphaned rollout files, goals, or subagent state behind.
## What
- Adds the v2 `thread/delete` request and `thread/deleted` notification,
with the response shape kept consistent with `thread/archive`.
- Implements local hard delete for active and archived rollout files.
- Deletes the requested thread's state DB row as the commit point, then
best-effort cleans associated state including spawned descendants,
goals, spawn edges, logs, dynamic tools, and agent job assignments.
- Updates app-server API docs and generated protocol schema/TypeScript
fixtures.
## 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.
## Why
Clients need to select a realtime session configuration for an
individual start without rewriting persisted configuration or restarting
the app-server process.
## What Changed
- Add optional `model` and `version` fields to `thread/realtime/start`
- Forward those optional values through the realtime start operation and
apply them only for that session
- Preserve existing configured/default behavior when the new fields are
omitted
- Update generated protocol schema and app-server documentation
## Validation
- Added/updated protocol serialization coverage for the new optional
request fields
- Added focused core coverage for a session override taking precedence
over configured realtime selection
- Added focused app-server coverage that a request override reaches the
realtime WebSocket handshake
## Why
CCA is moving toward a split runtime where the orchestrator may not have
a filesystem, while executors can expose preinstalled plugins and
skills. A thread therefore needs to select capabilities without asking
app-server or core to interpret executor-owned paths through the
orchestrator's filesystem.
The longer-term model is broader than executor skills:
- A plugin is a bundle of skills, MCP servers, connectors/apps, and
hooks.
- A plugin root can be local, executor-owned, or hosted by a backend.
- Components inside one plugin can use different access and execution
mechanisms. A skill may be read from a filesystem or through backend
tools; an HTTP MCP server can run without an executor; a stdio MCP
server or hook needs an execution environment.
- Core should carry generic extension initialization data. The extension
that owns a component should discover it, expose it to the model, and
invoke it through the appropriate runtime.
This PR establishes that architecture through one complete vertical:
selecting a root on an executor, discovering the skills beneath it,
exposing those skills to the model, and reading an explicitly invoked
`SKILL.md` through the same executor.
## Contract
`thread/start` gains an experimental `selectedCapabilityRoots` field:
```json
{
"selectedCapabilityRoots": [
{
"id": "deploy-plugin@1",
"location": {
"type": "environment",
"environmentId": "workspace",
"path": "/opt/codex/plugins/deploy"
}
}
]
}
```
The root is intentionally not classified as a "plugin" or "skill" in the
API. It can point at a standalone skill, a directory containing several
skills, or a plugin containing skills and other components. This PR only
teaches the skills extension how to consume it; later extensions can
resolve MCP, connector, and hook components from the same selection.
The platform-supplied `id` is stable selection identity. The location
says which runtime owns the root and gives that runtime an opaque path.
App-server does not inspect or canonicalize the path.
## What changed
### Generic thread extension initialization
App-server converts selected roots into `ExtensionDataInit`. Core
carries that generic initialization value until the final thread ID is
known, then creates thread-scoped `ExtensionData` before lifecycle
contributors run.
This keeps `Session` and core independent of the capability-selection
contract. The initialization value is consumed during construction; it
is not retained as another long-lived `Session` field.
### Executor-backed skills
The skills extension now owns an `ExecutorSkillProvider` that:
- resolves the selected environment through `EnvironmentManager`
- discovers, canonicalizes, and reads skills through that environment's
`ExecutorFileSystem`
- contributes the bounded selected-skill catalog as stable developer
context
- reads an explicitly invoked skill body through the authority that
listed it
- warns when an environment or root is unavailable
- never falls back to the orchestrator filesystem for an executor-owned
root
Skill catalog and instruction fragments have hard byte bounds, which
also bound them below the 10K-token per-item context limit. If a
selected executor skill has the same name as a legacy local skill, the
executor selection owns that invocation and the local body is not
injected a second time.
Existing local and bundled skill loading remains in place. Omitting
`selectedCapabilityRoots` therefore preserves current local-only
behavior.
## Current semantics
- Only environment-owned locations are represented in this first
contract.
- Roots are resolved by the destination extension, not by app-server or
core.
- An unavailable executor or invalid root produces a warning and no
capabilities from that root; it does not trigger a local-filesystem
fallback.
- Selection applies to a newly started active thread.
- MCP servers, connectors, and hooks beneath a selected plugin root are
not activated yet.
- Selection is not yet persisted or inherited across resume, fork, or
subagent creation. Existing local capabilities continue to behave as
they do today in those flows.
## Planned vertical follow-ups
1. **Hosted HTTP MCP:** add an extension-backed HTTP MCP source that
works without an executor, then replace the special-purpose MCP plugins
loader with that implementation.
2. **Executor MCP:** register and execute stdio MCP servers through the
environment that owns the selected plugin root.
3. **Backend skills:** add a hosted skill source whose catalog and
bodies are accessed through extension tools rather than a filesystem.
4. **Connectors and hooks:** activate those components through their
owning extensions, using the same selected-root boundary and
component-specific runtime.
5. **Durable selection:** define the desired-selection lifecycle,
persist it, and make resume, fork, and subagent inheritance explicit
rather than accidental.
6. **Local convergence:** incrementally route existing local plugin,
skill, and MCP loading through the same extension model while preserving
current local behavior.
Each follow-up remains reviewable as an end-to-end capability. The
platform selects roots, generic thread extension data carries the
selection, and the owning extension resolves and operates its component.
## Verification
Coverage added for:
- app-server end-to-end discovery and explicit invocation of a skill
inside an executor-selected plugin root
- exclusive invocation when a selected executor skill collides with a
local skill name
- executor filesystem authority for discovery, canonicalization, and
reads
- thread extension initialization before lifecycle contributors run
- stable executor catalog context, explicit invocation, context
rebuilding, hidden skills, and preserved host/remote catalog behavior
Targeted protocol, core-skills, skills-extension, core lifecycle, and
app-server executor-skill tests were run during development.
## Why
MCP startup failures from spawned subagents were rendered as global
notifications, so a child thread's failure could pollute the visible
parent transcript. Routing the notification to the child exposed two
related replay problems: session refresh could discard the buffered
event, and a newly created child `ChatWidget` did not know the expected
MCP server set, which could leave its startup spinner running after
every server had settled.
MCP startup diagnostics should remain visible in the thread that owns
the startup without affecting other transcripts. The protocol also needs
to support a future app-scoped MCP lifecycle where startup is not owned
by any thread.
## Reported Behavior
The [originating Slack
report](https://openai.slack.com/archives/C08JZTV654K/p1780604538859939)
called out that using subagents could turn MCP startup failures into a
wall of yellow CLI warnings because repeated failures were not
deduplicated. The intended behavior is for those diagnostics to remain
visible once in the thread that owns the startup, without polluting the
parent transcript.
## What Changed
- add nullable `threadId` ownership to `mcpServer/startupStatus/updated`
- populate it from the app-server conversation ID for the current
thread-scoped lifecycle and regenerate the protocol schema and
TypeScript artifacts
- treat a missing or null `threadId` as app-scoped without injecting it
into the active chat transcript
- route and buffer thread-owned MCP startup notifications by thread in
the TUI
- preserve buffered MCP startup events across child session refresh
- seed expected MCP servers before replaying a thread snapshot so
startup reaches its terminal state
- suppress an identical repeated failure warning for the same server
within one startup round
The owning thread still renders the detailed failure and final `MCP
startup incomplete (...)` summary.
## How to Test
1. Configure an optional MCP server named `smoke` that exits during
initialization.
2. Launch the TUI with multi-agent support enabled.
3. Confirm the main thread's own startup failure renders one detailed
`smoke` warning and one incomplete-startup summary.
4. Spawn exactly one subagent.
5. Confirm the parent transcript does not receive the subagent's MCP
startup failure.
6. Switch to the subagent thread and confirm it contains exactly one
detailed `smoke` failure and one incomplete-startup summary.
7. Confirm the subagent's MCP startup spinner disappears and the thread
remains usable.
8. Switch between the parent and subagent and confirm the warnings
neither move nor duplicate.
Targeted tests:
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server
thread_start_emits_mcp_server_status_updated_notifications`
- `just test -p codex-tui mcp_startup`
The parent/child behavior and spinner completion were also exercised
manually in tmux. `just argument-comment-lint` was attempted but blocked
by an unrelated local Bazel LLVM empty-glob failure; touched Rust
callsites were inspected manually.
## Why
Permission profile allowlists are an enterprise security boundary, but
they also need to compose across the managed requirements layers added
in #24620.
A map representation lets each requirements layer add, allow, or revoke
individual profiles without replacing an entire array.
## Managed Contract
Administrators configure the mergeable allow map with
`allowed_permission_profiles`. A recommended enterprise configuration
explicitly lists every built-in and custom profile users should be able
to select:
```toml
default_permissions = "review_only"
[allowed_permission_profiles]
":read-only" = true
":workspace" = true
review_only = true
# ":danger-full-access" is intentionally omitted, so it is denied.
[permissions.review_only]
extends = ":read-only"
```
- Profiles whose effective merged value is `true` are allowed.
- Missing profiles and profiles set to `false` are denied.
- This is a closed allowlist: built-in profiles and profiles introduced
in future versions are denied unless explicitly allowed.
- Explicitly list each built-in profile the enterprise wants to make
available. Omit built-ins such as `:danger-full-access` when they should
remain unavailable.
- Set `default_permissions` explicitly to the allowed profile users
should receive when they have no local selection.
- Higher-precedence layers override only the profile keys they define.
- `false` is only needed when a higher-precedence layer must revoke a
`true` inherited from a lower layer.
- Explicit keys must refer to known built-in or managed profiles.
A custom or narrowed allowlist requires an allowed
`default_permissions`. For compatibility, if both `:workspace` and
`:read-only` are explicitly allowed, an omitted default resolves to
`:workspace`; customer configurations should still set the intended
default explicitly.
When `allowed_permission_profiles` is absent, existing implicit
permission and legacy `sandbox_mode` behavior is unchanged.
## What Changed
- Add `allowed_permission_profiles` as a `BTreeMap<String, bool>` that
merges per profile across requirements layers.
- Enforce managed defaults, strict denial of omitted profiles, and the
explicitly allowed standard-pair fallback.
- Expose `allowedPermissionProfiles` through `configRequirements/read`
and regenerate its schemas.
- Add regression coverage for map composition and revocation, managed
defaults, strict denial of omitted built-ins, and API output.
## Verification
- Focused `codex-config` coverage for layered map composition and
revocation
- Focused `codex-core` coverage for managed defaults, invalid defaults,
strict denial of omitted built-ins, and the standard built-in pair
- Focused `codex-app-server` coverage for requirements API output
- Scoped Clippy for `codex-config`, `codex-core`,
`codex-app-server-protocol`, and `codex-app-server`
## Documentation
The managed `requirements.toml` documentation should introduce
`allowed_permission_profiles` as a closed permission-profile allowlist
before this setting is published on developers.openai.com.

## Summary
- add v2 personal access token support for `codex login
--with-access-token` and `CODEX_ACCESS_TOKEN`
- classify opaque `at-` tokens separately from legacy Agent Identity
JWTs
- hydrate required ChatGPT account metadata through AuthAPI
`/v1/user-auth-credential/whoami`
- use PATs directly as bearer tokens while preserving existing ChatGPT
account surfaces
- expose PAT-backed auth as the explicit `personalAccessToken`
app-server auth mode
## Implementation
PAT auth is intentionally small and stateless. Loading a PAT performs
one AuthAPI metadata request, stores the hydrated metadata in the
in-memory auth object, and redacts the secret from debug output. Legacy
Agent Identity JWT handling remains unchanged. The shared access-token
classifier lives in a private neutral module because it dispatches
between both credential types.
PAT hydration fails closed when AuthAPI omits any required metadata,
including email. Hydrated metadata is intentionally not persisted:
startup performs a live `whoami` preflight so revoked tokens or changed
account metadata are not accepted from a stale cache.
## Workspace restriction scope
This change intentionally does **not** apply
`forced_chatgpt_workspace_id` to PAT authentication. The setting is a
client-side config guardrail, not an authorization boundary, and PAT
does not currently require workspace-ID parity. The PAT login and
`CODEX_ACCESS_TOKEN` paths therefore validate through AuthAPI without
threading workspace-restriction state through access-token loading.
Existing workspace checks for non-PAT auth remain on their established
paths.
## App-server compatibility
The public app-server `AuthMode` is shared across v1 and v2, and
PAT-backed auth reports `personalAccessToken` through both APIs.
Following human review, this intentionally removes the temporary v1
compatibility mapping that reported PATs as `chatgpt`; the deprecated v1
API is kept in parity with v2 rather than maintaining a separate closed
enum. Clients with exhaustive auth-mode handling in either API version
must add the new case and should generally treat it as ChatGPT-backed
unless they need PAT-specific behavior.
The v1 auth-status response still omits the raw PAT when `includeToken`
is requested because that response cannot carry the account metadata
needed to reuse the credential safely. Persisted PAT auth also omits the
new enum value so older Codex builds can deserialize `auth.json` and
infer PAT auth from the credential field after a rollback.

The broader `codex-tui` suite previously compiled and ran 2,834 tests.
Three unrelated environment-sensitive guardian/IDE-socket tests failed
after retries; the PAT-relevant TUI coverage passed.
Stacked on #26532.
## Why
#26532 moves cwd normalization to the app-server/core boundary.
`runtimeWorkspaceRoots` still accepted raw paths in v2 requests and in
`ConfigOverrides`, which left core responsible for interpreting those
roots later. This makes runtime workspace roots follow the same
absolute-path boundary as cwd.
## What
- Change v2 `runtimeWorkspaceRoots` request fields for `thread/start`,
`thread/resume`, `thread/fork`, and `turn/start` to `AbsolutePathBuf`.
- Deduplicate already-absolute runtime roots in app-server handlers and
pass them through `ConfigOverrides.workspace_roots` as
`AbsolutePathBuf`.
- Update TUI and exec client request builders to pass absolute runtime
roots directly.
- Update app-server docs, schema fixtures, and focused tests for
absolute runtime roots.
## Testing
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server runtime_workspace_roots`
- `just test -p codex-core
session_permission_profile_rebinds_runtime_workspace_roots`
- `just test -p codex-tui app_server_session`
- `just test -p codex-exec`
## 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
Token activity is useful account-level context, but terminal clients
need a supported app-server path to fetch it without reaching into
ChatGPT backend details directly. The API should also live under the
broader account usage umbrella so future usage surfaces can be added
without proliferating user-facing concepts.
## What Changed
- Add `codex-backend-client` support for the ChatGPT profile token-usage
payload.
- Add the v2 `account/usage/read` app-server RPC.
- Map lifetime usage, peak daily usage, streak, longest task duration,
and daily buckets into app-server protocol types.
- Gate the request on Codex-backend auth, which supports ChatGPT auth
tokens and AgentIdentity.
- Regenerate the app-server JSON and TypeScript schema fixtures.
## Token Count Source
`account/usage/read` returns the token-usage aggregate supplied by the
ChatGPT profile backend. App-server maps that backend-owned aggregate
into protocol fields; it does not recompute cached-token treatment,
usage multipliers, or raw input/output totals locally.
## Stack
1. feat(app-server): expose account token usage [1 of 2] (this PR)
2. [#25345](https://github.com/openai/codex/pull/25345) feat(tui): add
token activity command [2 of 2]
## How to Test
1. Start an app-server client from this branch while authenticated with
ChatGPT or AgentIdentity.
2. Call `account/usage/read`.
3. Confirm the response includes `summary` and `dailyUsageBuckets`.
4. Also verify a session without Codex-backend auth receives the
existing auth error path.
Targeted tests:
- `just test -p codex-backend-client -p codex-app-server-protocol -p
codex-app-server`
- `just write-app-server-schema`
## Why
First-party backends can supply turn-scoped moderation metadata that
app-server clients need for client-side presentation. Exposing this as
an experimental typed notification lets opted-in clients consume it
without interpreting raw Responses API events.
## What changed
- forward `response.metadata.openai_chatgpt_moderation_metadata` from
Responses API SSE and WebSocket streams as turn-scoped moderation
metadata
- emit the experimental app-server v2 `turn/moderationMetadata`
notification with `{ threadId, turnId, metadata }`
- add app-server integration coverage for the typed moderation metadata
notification
## Testing
- `just test -p codex-core
build_ws_client_metadata_includes_window_lineage_and_turn_metadata`
- `just test -p codex-core` (fails locally: 46 failures and 1 timeout,
primarily missing `test_stdio_server` and shell snapshot timeouts)
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server
turn_moderation_metadata_emits_typed_notification_v2`
- `just test -p codex-app-server` (fails locally: 792 passed, 10 failed,
and 5 timed out; failures are in existing environment-sensitive tests,
primarily because nested macOS `sandbox-exec` is not permitted)
- `just write-app-server-schema --experimental --schema-root
/tmp/codex-app-server-schema-experimental`
