## What changed
- Add an optional `toolOutput` to `turn/start` for starting or steering a turn with a named function-call output instead of user input.
- Emit standalone outputs as `functionCallOutput` thread items, persist them in durable history, and include them in resumed threads.
- Validate that tool outputs have a name, are not combined with nonempty `input`, satisfy the text-size limit, and use supported image URLs.
## Testing
- Cover standalone tool-output notifications, model input, and resumed history in both legacy and paginated history modes.
- Cover the text-size limit for structured tool output.
GitOrigin-RevId: a1eeec7b9b7de67b1a1c5e829a54552b85ec118b
## What changed
- Add the `write_stdin_approval` feature flag, disabled by default, to require a fresh approval before sending non-empty input to an escalated unified-exec terminal.
- Route these reviews through hooks, Guardian, app-server, and the TUI as `writeStdin` approvals while keeping the parent command item unchanged.
- Preserve the terminal environment, launch directory, and escalation state across turns, and revalidate the process identity after approval before writing input.
## Testing
- Cover approval routing, policy decisions, process reuse, terminal identity preservation, app-server events, analytics, and TUI rendering.
GitOrigin-RevId: 4ba29eaae6208e934737ba078c96e589c7c2164d
## What changed
- Resolve plugin activation, MCP server policy, and marketplace definitions from the effective configuration stack, including system settings and trusted project overrides.
- Load plugin skills independently for each working directory passed to `skills/list`.
- Exclude project configuration from catalog requests whose `cwds` are omitted or empty.
- Cache up to eight loaded plugin configurations with least-recently-used eviction so requests for different working directories can reuse their results.
## Testing
- Cover layered plugin and MCP policy across trusted and untrusted projects.
- Cover per-directory skill and plugin catalog results, cache reuse and eviction, and system-defined marketplaces.
GitOrigin-RevId: cb68b2b1bdab1da48e05ca7562bc05014431fc71
## Why
App-server clients need the explanation and steering instruction returned with a
misalignment policy violation to offer a user-confirmed continuation. Missing or
incomplete details must continue to behave as a terminal block.
## What changed
- Parse optional misalignment classification, explanation, and steering details
from streamed and HTTP Responses errors and propagate them through core errors.
- Include the details in live app-server `error` and `turn/completed` payloads and
export the corresponding protocol schemas and TypeScript types.
- Keep explanations and steering messages out of serialized rollout events and
redact them from debug output.
- Document how clients can resume with `turn/start` after user confirmation.
## Testing
- Cover streamed, HTTP, and WebSocket-wrapped errors, including malformed and
classification-only details.
- Verify live app-server notifications expose resumable details without writing
the explanation or steering message to the rollout.
GitOrigin-RevId: 329258a444c2cd91d0c57ab1720830b33ddcfac5
## What changed
- Classify `response.failed` events with the `rate_limit_exceeded` code as a distinct retryable error while preserving any parsed retry delay.
- Expose the error as `rateLimitExceeded` through the core protocol and app-server schemas after stream retries are exhausted.
- Preserve the upstream message for TUI display while keeping it out of telemetry summaries.
## Testing
- Cover SSE classification, retry metadata, protocol conversion and serialization, exhausted stream retries, telemetry redaction, and TUI rendering.
GitOrigin-RevId: 02dab4d3477dcd7653a58c49c4bd38687a616579
## What changed
- Accept only `http://` and `https://` gRPC endpoints for app server
`--code-mode-host` connections.
- Limit the standalone code-mode host to stdio and gRPC listeners.
- Remove the WebSocket session provider, dual-WebSocket negotiation, transport
lanes, and related dependencies and tests.
- Keep coverage for shared and prewarmed gRPC hosts and reject WebSocket host
URLs in CLI parsing tests.
GitOrigin-RevId: 8792604e79ffd54ce776074a4dc3f7d55e63752a
## What changed
- Add the experimental `turn/start.cyberAccessProgram` option with `standard`,
`daybreakBlue`, and `daybreakRed` values.
- Forward the selection as `access_programs.cyber` on Responses, WebSocket,
and remote-compaction requests made with ChatGPT authentication, while
omitting it for API-key and custom-provider requests.
- Preserve the per-turn selection across recovery, compaction, and child-agent
turns without making it a persistent thread setting.
## Testing
- Cover app-server forwarding, authentication boundaries, WebSocket reuse,
turn recovery, compaction, and child-agent inheritance.
GitOrigin-RevId: d2eb468f365b2214c5099bc21741cf30f8bd2eb5
## Why
Removing a base-user marketplace must not delete a snapshot that is still
referenced by another enabled configuration layer.
## What changed
- Load the current configuration stack for marketplace commands in the CLI and
app server.
- Reject removal when a matching marketplace is defined by another enabled
layer, and identify the configuration source that must be updated instead.
- Allow cleanup of an installed marketplace snapshot even when no base-user
entry exists.
## Testing
Cover project, enterprise-managed, system, and session-flag configurations, as
well as snapshot-only removal through the CLI and app server.
GitOrigin-RevId: 4f0853a40c2b5fae0410696b79eee4284239c7a9
## What changed
When `thread/start` omits `historyMode`, select `paginated` for durable
threads whose store supports `thread/turns/list` and `thread/items/list`.
Continue to default ephemeral threads and threads backed by stores without
those APIs to `legacy`.
Explicit `legacy` and `paginated` selections keep their existing behavior.
## Testing
- Verify durable threads use paginated history with the local store.
- Verify ephemeral threads and stores without history-list support use legacy
history.
GitOrigin-RevId: c94b6a3b522049d541da33c41618c4142370f1a7
## Why
Paginated thread history should be loaded incrementally through
`thread/turns/list` and `thread/items/list` instead of being fully reconstructed
in `thread.turns`.
## What changed
- Emit `deprecationNotice` when `thread/read`, `thread/resume`, or `thread/fork`
requests full history for a paginated thread.
- Direct clients to omit `includeTurns` for reads or use `excludeTurns: true` for
resumes and forks, then page history through the list APIs.
- Document the deprecation in the protocol schemas and app-server README.
## Testing
- Cover notices for paginated reads, cold and loaded resumes, and forks.
- Verify metadata-only requests, legacy threads, and rejected forks do not emit
the notice.
GitOrigin-RevId: 0d387b46d73608f90b7960120a54af4ef332e510
## What changed
- Make `thread/turns/list`, `thread/items/list`, and `thread/revert` available
without the experimental API capability.
- Stabilize `thread/reverted`, `thread.historyMode`, and the pagination fields
used by `thread/resume` and `thread/fork`.
- Publish the promoted requests, responses, and fields in the stable JSON and
TypeScript schemas, and update the app-server documentation accordingly.
GitOrigin-RevId: 18b8c53c265211597bb1a62fd62f66f4a3df5f06
## What changed
- Add an optional `turnTrigger` field to app-server `turn/start` requests and
expose it in the generated protocol schemas.
- Propagate non-empty trigger values to Responses request metadata as the
reserved `turn_trigger` field, while preserving the original value when a
request steers an active turn.
- Classify turns started by queue dispatch, goal continuation, retry recovery,
and realtime handoff.
## Testing
- Cover HTTP and WebSocket metadata forwarding, steering behavior, reserved
metadata handling, and the built-in trigger classifications.
GitOrigin-RevId: c12fe2c522286db21b76081ae6154fbf6bfb3639
## 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 `serviceTierForTurn` to `turn/start` so a newly started turn can override the service tier without changing the thread's saved tier.
- Treat `"default"` as standard speed and omitted or `null` values as inheriting the thread tier.
- Keep `serviceTier` authoritative for subsequent turns when both fields are supplied, and ignore the turn-scoped override when steering an active turn.
## Testing
- Extend the app-server turn-start test to verify both the one-turn `"default"` override and inheritance on the following turn.
GitOrigin-RevId: 4c2c4db21d8d31617a7a6e6df65bf54834e72383
## What changed
- Record collaboration tool analytics for `send_message`, `followup_task`,
`interrupt_agent`, and `list_agents`, including receiver attribution, duration,
failures, and interrupted calls.
- Include these calls in per-turn subagent tool counts while keeping the existing
`subAgentActivity` output unchanged and omitting additional public collaborator
tool items.
- Extend the collaboration tool schemas with the new tool variants and the
`interrupted` terminal status.
## Testing
- Add an app-server integration test covering successful and failed calls,
receiver attribution, duration, prompt omission, activity items, and turn
counts.
GitOrigin-RevId: e73eaa05c508261e5fc97e7d08d7881a31e04e22
## What changed
- Add a `writeStdin` Guardian action carrying the approval, process, input, and working-directory details.
- Distinguish `command` and `writeStdin` execution approval requests while defaulting missing kinds to `command` for compatibility with older events.
- Render terminal-input review progress, denials, timeouts, and retry actions in the TUI, and record the action separately in analytics.
- Keep terminal-input reviews as child approvals so they do not change the parent command item's lifecycle or reconstructed history.
## Testing
- Cover Guardian serialization, app-server protocol conversion, command history reconstruction, analytics classification, and TUI review flows for terminal input.
GitOrigin-RevId: b083d5e2963bdd23b928644ec03c7eb68ebf2950
## Why
Clients need a bounded view of realtime conversations that preserves the order of speech, agent work, and turn lifecycle events without loading the full thread history.
## What changed
- Persist realtime session boundaries, transcript segments, and promoted agent items in paginated thread rollouts.
- Add the experimental `thread/timeline/list` API to page ordinary items, realtime items, and turn boundaries in canonical rollout order. Include `activeRealtimeSessionAtPageStart` so each page can be rendered independently.
- Emit typed `thread/realtime/item/started`, `thread/realtime/item/transcript/delta`, and `thread/realtime/item/completed` notifications around durable realtime items.
- Keep the existing `thread/items/list` response and legacy thread history behavior unchanged.
## Testing
- Cover mixed timeline pagination, realtime-session state at page boundaries, rollout replay, subagent history prefixes, transcript streaming, steering, and promoted agent artifacts.
GitOrigin-RevId: faa2c420192d63e060e8fb32446e3c797422656e
## Why
Unified `@` search could show a plugin alongside the skills it owns, creating duplicate entry points for the same capability.
## What changed
- Add a nullable `pluginId` to `SkillMetadata` returned by `skills/list` so clients can associate skills with their owning plugin without inspecting names or paths.
- Hide a plugin's owned skills from unified `@` results when that plugin is present, while retaining standalone skills and skills with unknown ownership.
- Keep `$` focused on individual skills and apps, and use it consistently as the skills-list shortcut. Preserve the legacy mention behavior when `mentions_v2` is disabled.
## Testing
- Cover plugin ownership in `skills/list` and the updated `@` and `$` composer results.
GitOrigin-RevId: e168cdff8d0c58f74ce4c228a683880a3167775b
## What changed
- Add the experimental `amazonBedrockAccessKeys` app-server login flow, persist its credentials in the configured auth store, and use them for SigV4-signed Bedrock requests.
- Report `bedrockAccessKeys` as a distinct auth mode and document access-key login alongside AWS profile and environment credential setup.
- Clear the selected Bedrock provider, AWS settings, and Bedrock-specific model on logout while leaving external AWS credentials and `.env` untouched.
- Reject managed access-key login when higher-precedence configuration would prevent its region or profile settings from taking effect.
## Testing
- Cover access-key login, storage, request signing, configuration conflicts, status reporting, and logout cleanup.
GitOrigin-RevId: bbf297887c6503d3651ceb2aad85c4d626e32723
## Why
Multi-Agent V2 children are owned by their parent at runtime. Resuming an
unloaded child directly could rebuild it from caller-provided settings instead
of the parent's current authority.
## What changed
- Route child reloads through their loaded immediate parent and reject direct
cold resume when that parent is unavailable.
- Preserve the child's recorded model, provider, reasoning effort, and role
while inheriting the parent's execution policy and MCP extensions.
- Validate cached environments against the parent, intersect local permission
profiles, and reject stale remote or workspace-root configurations.
- Keep paginated cold-resume token usage attribution when attaching to the
reloaded child.
## Testing
Add coverage for owner validation, nested-parent reloads, permission and
environment changes, role instruction restoration, paginated usage replay,
and app-server child resume behavior.
GitOrigin-RevId: 84014762bcdb57f94fc23974c9c1af55dc1babf1
## Why
Parent-owned Multi-Agent V2 subagents must remain controlled by their parent,
but several app-server endpoints could still mutate them directly.
## What changed
- Centralize the direct-input ownership check and apply it to turn injection,
MCP calls, reviews, compaction, rollback and revert, shell and Guardian
actions, realtime requests, and goal mutations.
- Enforce the same policy for goal mutations on unloaded threads while keeping
goal reads and turn interruption available.
- Document the affected endpoint behavior and continue exposing
`canAcceptDirectInput: false` for parent-owned subagents.
## Testing
- Cover direct-input rejection for both legacy and paginated thread history.
- Cover goal mutation ownership checks for unloaded V2 subagents, V1
subagents, and non-subagent V2 threads.
GitOrigin-RevId: 791b7af98490aed5eab4e672b90661acad11ec23
## Why
A Multi-Agent V2 child can finish after the parent turn that spawned it, so its
successful completion needs to remain associated with that parent turn in
notifications and history.
## What changed
- Add `completed` to `SubAgentActivityKind` and emit the corresponding started
and completed item events on the spawning parent turn when a child succeeds.
- Persist completed activity as a canonical turn item in both legacy and
paginated history, and expose it through app-server history and schemas.
- Render completed activity as terminal in the TUI without counting it as a
separate tool call or tool-runtime event.
## Testing
- Cover successful completion in legacy and paginated history, late updates to
completed parent turns, TUI rendering, analytics, and rollout tracing.
- Verify that terminal child errors do not emit completed activity.
GitOrigin-RevId: 6c71eb8b10e7327611c6af84f70e294e27d94d02
## Why
MCP inventory can be cached or collected separately from a thread's live
connections, so tool availability alone does not describe the current runtime
state.
## What changed
- Add a nullable `runtimeStatus` to `mcpServerStatus/list` for thread-scoped
requests, covering not-started, starting, connected, authentication-required,
failed, cancelled, and disabled connections.
- Observe published connection state without starting or reconnecting servers,
and return an unknown status when no thread is supplied or the active
configuration no longer matches the published registration.
- Show connection state and tool counts in the compact `/mcp` view while
retaining the detailed inventory in `/mcp verbose` and compatibility with
servers that omit `runtimeStatus`.
## Testing
- Cover runtime status transitions, deferred and disabled servers, closed
transports, configuration changes, protocol compatibility, and TUI rendering.
GitOrigin-RevId: e3bb6efe652f0fa8b3c97d5c53e4729b3a87cd91
## What changed
- Expand `configRequirements/read` with the Browser/Computer Use umbrella
policy and the complete browser-use policy, including origin-specific access,
download, upload, auto-review, and approval controls.
- Return computer-use persistent approval, default app access, macOS bundle ID
rules, and Windows AUMID and executable rules.
- Export the corresponding v2 protocol types and generated JSON and TypeScript
schemas.
## Testing
- Extend the config requirements RPC test to cover the new browser and
platform-specific computer-use fields.
GitOrigin-RevId: d1be93388701b06312a26853d640401b63b4d535
## Why
Clients that create and negotiate realtime calls themselves need Codex to join
those calls without creating another call or overwriting the client-owned
session configuration.
## What changed
- Add the `existingCall` transport to `thread/realtime/start`, accepting a
client-provided `callId` and optional `realtimeSessionId`.
- Attach Codex over the call's sideband WebSocket without SDP negotiation or a
session update, and reconnect that sideband while preserving transcript
state.
- Default existing calls to realtime v1, support v1 and v3, and reject v2 or
options that would reconfigure the client-owned session.
- Encode call IDs as a single URL path segment for v3 sideband connections.
## Testing
Add protocol, app-server, core, reconnection, authentication-header, and URL
encoding coverage for existing-call attachments.
GitOrigin-RevId: 2046b70566f98efa55381bb1e461ea3cc68256c5
## What changed
- Apply the existing direct-input restriction to `thread/settings/update` for
parent-owned Multi-Agent V2 subagents.
- Document the restriction and extend the direct-input test to verify that the
request returns an invalid-request error.
GitOrigin-RevId: 2eead01c6f54ec637c68573378f3b56a7ee85652
## Why
External tool events may need to enter thread history without a preceding function call and therefore do not have a `call_id`.
## What changed
- Allow `function_call_output` items to omit `call_id` and carry optional `name` and `namespace` fields.
- Preserve named standalone outputs during history normalization and agent forks while retaining existing pairing behavior for outputs with a `call_id`.
- Accept, persist, and forward these outputs through `thread/inject_items`, and update the app-server schemas and documentation.
## Testing
- Cover paired and standalone JSON round trips, history normalization, agent forks, and injected thread history.
GitOrigin-RevId: a3258163a7dc93777c7c3023116fe204819bdbb0
## What changed
- Add experimental `mcpServer/event/stream/start` and `mcpServer/event/stream/stop` requests for hosted apps, plus `mcpServer/event/stream/notification` forwarding.
- Scope subscriptions to the owning app-server connection and subscribed thread, enforce unique IDs and a per-connection limit, and clean them up when the thread is unsubscribed or the connection closes.
- Wait for the MCP active notification before completing startup, retry streams that close immediately, and terminate them when authentication or hosted runtime ownership changes.
## Testing
- Add an app-server integration test covering activation, event forwarding, duplicate subscription rejection, and explicit cancellation.
GitOrigin-RevId: 8a6fc1615adfc5af7e67def3b824fa5909ab3e7b
## What changed
- Add `additional_developer_instructions` to managed requirements and expose it through `configRequirements/read` as `additionalDeveloperInstructions`, independently of ordinary developer instructions.
- Include the managed instructions in model context, emit explicit replacement or removal messages when requirements change, and preserve the current value across compaction, resume, and agent forks without duplication.
- Reject managed instructions whose rendered context exceeds 10,000 estimated tokens.
## Testing
- Cover requirements layering and API serialization, context updates and removal, size validation, repeated model requests, compaction and resume, rollout migration, and agent forks.
GitOrigin-RevId: bc0b70fb7988944c2f68176dff55f5ed61eb46c8
## What changed
- Add `in_app_browser.allow_external_browser_settings_import` to managed requirements, preserving explicit Boolean values through layered composition while leaving an omitted value unset.
- Return the policy as `inAppBrowser.allowExternalBrowserSettingsImport` from `configRequirements/read` and include it in the generated protocol schemas.
- Keep the import policy independent from the in-app browser feature flag and agent Browser Use requirements.
## Testing
- Cover parsing, managed-layer precedence, invalid values, user and session override resistance, and app-server response serialization.
GitOrigin-RevId: efa2621d2b1cf503f1bee2505d9914cb4fb7221d
## Why
New non-ephemeral threads have no persisted rollout or preview until their first
turn, so moving them into a section could leave them absent from section-filtered
thread lists.
## What changed
- Materialize and flush a non-ephemeral thread before applying an explicit
section move.
- Include explicitly sectioned threads with empty previews in section-filtered
queries, and update the partial indexes to cover them.
## Testing
- Add an app-server test that moves a newly started thread into and out of the
pinned section before its first turn.
- Cover empty-preview threads in recency and section-position query tests.
GitOrigin-RevId: aa3c4daf9890f06c08b93cd60f146099cbc6cfb2
## What changed
- Add an optional `delivery` field to agent message events and app-server
`agentMessage` items, with `"async"` identifying a user-visible message sent
without ending the current turn.
- Preserve the marker through legacy event conversion, thread history
materialization, replay, and generated JSON and TypeScript schemas.
- Require delivery of async agent message completion notifications on the
in-process app-server transport.
## Testing
- Cover preservation of async delivery metadata in thread history.
- Cover delivery-required classification for async agent messages.
GitOrigin-RevId: f92ba25de1293ee271404badfdf0d117d6530329
## What changed
- Add an optional `connectorId` to `mcpServer/resource/read`.
- Forward the selected connector through `x-codex-turn-metadata` for threaded and threadless resource reads, restricting hosted app resources to that connector.
- Update the generated protocol schemas and app-server documentation.
GitOrigin-RevId: 5cc94d703abbbb6086665910c1c9ed5dc7075210
## Why
App widgets need to read resources using the app and account context of the
tool call that produced them, including after a thread is restored.
## What changed
- Add an optional `originCallId` to `mcpServer/resource/read` requests and
return it on successful scoped reads.
- Track bounded provenance for successful app tool calls in thread history and
use the current tool binding, account link, and app policy when reading the
associated widget resource.
- Reject missing, mismatched, failed, or ambiguous origins, while keeping
app-only tools available for widget reads without exposing them to the model.
## Testing
Add app-server coverage for scoped widget reads across both history modes,
ephemeral and persistent threads, server restarts, app-only visibility, and
invalid origin cases.
GitOrigin-RevId: 11eaefc066b2a3b639599e4cbdef680233d150a2
## What changed
- Add the experimental `autoApprovalReview/strictReviewRequired` app-server notification with the review's `threadId`, `turnId`, and `startedAtMs`.
- Emit it when Guardian v2 leaves an approval review in progress because the action risk is elevated or its score is stale.
- Export the notification through the Rust, TypeScript, and JSON schema surfaces and route it to the associated thread.
## Testing
- Cover strict-review reason tracking for elevated and stale risk scores.
- Verify that high-risk approval routing emits one notification whose identifiers and timestamp match the review-started event.
GitOrigin-RevId: e65352894520bfb756c75b2c95e2e149f9767bb2
## Why
Cold resumes and forks could lose the thread's active permission profile and
fall back to the current configured default.
## What changed
- Restore the latest persisted approval policy, approvals reviewer, and active
permission-profile ID when resuming or forking a thread.
- Re-resolve persisted profile IDs through current configuration and
requirements. Missing or invalid profiles fall back to the configured
default, while threads without a persisted profile continue to use current
configuration.
- Keep explicit permission and approval overrides ahead of persisted settings.
## Testing
Added coverage for legacy and paginated histories, settings updates, explicit
overrides, removed or changed profiles, requirement fallbacks, and forks.
GitOrigin-RevId: 2289af2f3206bf131a6ffe0e8447e8d402e76c47
## What changed
- Add `cli_auth_credentials_store` and `chatgpt_base_url` as exact managed requirements loaded from local requirements configuration.
- Apply these requirements to runtime and bootstrap authentication configuration, overriding user-configured values.
- Expose the managed values through `configRequirements/read` and reject attempts to change them through config write APIs.
- Ignore these local-only authentication requirements in cloud-managed requirement layers.
## Testing
- Cover requirement loading and composition, runtime and bootstrap overrides, app-server responses, and read-only config writes.
GitOrigin-RevId: 8ea9c096386072036ca5441f3d48af8707988a65
## What changed
- Discover synchronous `mcp_tool` hook handlers and invoke their configured MCP server and tool through a supplied executor.
- Expand nested hook-event placeholders in MCP tool inputs while preserving JSON types, and process tool output through the existing hook output contract.
- Represent hook details as handler-specific metadata in `hooks/list`, including MCP server and tool fields, and show those details in the TUI hooks browser.
- Skip unsupported `SessionEnd` MCP hooks and runtimes without MCP invocation support with startup warnings.
## Testing
- Cover argument expansion, missing placeholders, MCP invocation and hook decisions, discovery warnings, `hooks/list` metadata, and TUI rendering.
GitOrigin-RevId: 295b845471fe92bd7ad7cd272fbcd2c3713912e0
## What changed
- Recognize `misalignment_policy_violation` errors from response streams and HTTP 400 or 403 responses.
- Preserve the upstream message, use a fallback for blank messages, and treat the error as non-retryable.
- Expose `misalignmentPolicyViolation` through the app-server protocol and generated schemas so turns fail with a typed terminal error.
## Testing
- Cover streamed and HTTP policy violations, fallback messages, retry behavior, and app-server turn completion.
GitOrigin-RevId: fd3485bf0be7bfe3d51c078bbc36a081692fd57f
## What changed
- Add experimental `thread/queue/add`, `list`, `update`, `delete`, `reorder`, and `start` requests for persistent queued user submissions.
- Automatically dispatch queued submissions in FIFO order after completed or failed turns, while leaving the queue paused after interruption.
- Emit `thread/queue/changed` notifications and expose paginated queue contents with stable submission and client message IDs.
- Export the new protocol types through the generated JSON Schema and TypeScript bindings.
## Testing
- Add app-server integration coverage for capability gating, CRUD, pagination, capacity limits, notifications, automatic dispatch, cold-thread resume, interruption, and explicit queue starts.
GitOrigin-RevId: 89caf5577192199bda77cf6c372a59d26cdd910e
## What changed
- Parse the optional `retirement_at` RFC 3339 value from model upgrade metadata, treating missing, null, or malformed values as unknown.
- Expose known retirement times from `model/list` as nullable Unix timestamps in `upgradeInfo.retirementAt` and preserve them when converting app-server models back into model presets.
- Update the generated protocol schemas and app-server documentation.
## Testing
- Cover absent, null, valid, and malformed catalog values.
- Verify `model/list` serialization and app-server model conversion for known, missing, and out-of-range timestamps.
GitOrigin-RevId: 969baf9f5b012997f460fb4611ba63c963ee658c
## What changed
- Add the experimental `thread/revert` request, which replaces a loaded paginated thread's durable history with the prefix before `beforeTurnId` while preserving the thread ID.
- Interrupt any active turn, reload the replacement history without unloading the thread, preserve mutable thread settings, and emit `thread/reverted`.
- Return backward pagination cursors for the retained turns and items, reject stale rollout paths after a revert, and document that local file changes are unaffected.
## Testing
- Cover history replacement, pagination, stale paths, missing turns, subsequent turns, active-turn interruption, and preserved thread settings.
GitOrigin-RevId: 435a8163ad4f310cc47219b436f6bdde21f2b83a
## What changed
- Keep the configured `approvalPolicy` when a model in
`auto_review.required_on_models` selects the `auto_review` reviewer.
- Continue downgrading full-access sessions to workspace-write and rejecting
incompatible reviewer overrides.
## Testing
- Cover supported approval policies across thread start, settings updates,
turn-time model switches, resume, and fork flows.

## What changed
- Accept root `http://` and `https://` URLs in `--code-mode-host` and use the
shared gRPC session provider for those endpoints.
- Keep `ws://` and `wss://` URLs on the existing WebSocket transport.
- Reject paths, queries, fragments, and credentials where unsupported, without
exposing gRPC URL credentials in command-line validation errors.
## Testing
- Cover argument parsing and transport selection for both remote protocols.
- Exercise a gRPC host shared across app-server threads and verify credential
rejection does not disclose usernames or passwords.

## 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.

## What changed
- Make automatic MCP OAuth registration prefer Client ID Metadata Documents
(CIMD) when the authorization server advertises support for public clients and
Codex is using its native loopback callback. Fall back to advertised Dynamic
Client Registration (DCR) otherwise.
- Add explicit `cimd` and `dcr` registration overrides to the CLI and app-server
OAuth login API. Validate CIMD metadata and callback URLs before starting the
authorization flow.
- Use a callback-specific Codex client metadata URL for CIMD and retain the
exact redirect URI through authorization and token exchange.
## Testing
- Cover automatic and forced CIMD selection, DCR fallback, invalid metadata and
redirects, token refresh, authenticated MCP requests, and conformance
regression checks.

## What changed
Remove `openai/standard-form-input` from the documented app-server capability
extensions and initialization example. Continue to document `openai/form` for
extended form support.
GitOrigin-RevId: e1f313bec99a7fdc3462c8002181a8cdc48ad558
## What changed
- Add `--oauth-client-registration` with `auto` and `dcr` choices to `codex mcp add` and `codex mcp login`.
- Add the equivalent optional `clientRegistration` field to `mcpServer/oauth/login` and the generated protocol schemas.
- Keep automatic dynamic client registration as the default, prefer a configured OAuth client ID when present, and apply the selection only to the current login without persisting it in MCP configuration.
## Testing
- Cover dynamic registration and configured-client OAuth flows through the app server.
- Verify the CLI does not persist the per-login registration choice.

## What changed
- Add optional `icon` and `color` appearance fields to custom thread sections and expose them through the app-server protocol.
- Persist appearance metadata in SQLite and include it when listing sections or returning threads.
- Let `threadSection/update` preserve an omitted appearance, clear it with `null`, or replace it with a new value.
- Reject appearance fields larger than 64 bytes.
## Testing
- Cover protocol compatibility, persistence across restart, update and clear behavior, and field-length validation.
