## Why
Custom-provider sign-in previously required a saved gateway configuration and stopped at an error when none existed.
## What changed
- Add “Create a custom provider or gateway” to the sign-in picker, reusing the settings form and provider-write handling.
- Return to the picker after saving, highlight the new provider, and require explicit selection before setting it as the default and completing sign-in.
- Preserve entered fields after validation failures and keep the focused field or Save action visible in short terminals.
- Use consistent custom-provider and gateway wording across sign-in, settings, and validation messages.
## Testing
Add onboarding tests and snapshots for an empty picker, creation, validation retries, short-terminal rendering, and explicit default selection. Extend app-server coverage for rejecting the reserved `ollama-chat` provider ID.
GitOrigin-RevId: 339ac5807c5eecdae08df4dbd89874ea7c764d35
## Why
Invalid assertions and paused or revoked runtime instances cannot recover through request retries or credential refresh. Permanent refresh-token failures also need to retain their sign-in error instead of becoming retryable stream errors.
## What changed
- Recognize terminal runtime denial codes in `401` and `403` response bodies and identity error headers, preserving HTTP diagnostics while stopping retries.
- Skip credential recovery for runtime denials in runtime-enabled model providers and backend requests, while preserving recovery for ordinary credential expiration.
- Propagate permanent refresh-token failures through runtime authentication as `RefreshTokenFailed` errors.
## Testing
Add coverage for body and header denials, preserved HTTP diagnostics, provider-scoped credential recovery, and cached permanent refresh failures. Complete-turn tests verify that runtime denials stop without retries or refreshes while expired credentials recover in both runtime authentication modes.
GitOrigin-RevId: 33f6f707454130e97e13f3b53e29d2c484602152
## Why
Security reminder requests need to use app-server's active authentication and HTTP runtime, with results bound to the login that fetched them.
## What changed
- Add `account/securitySetup/read`, returning an optional notice with account and user IDs, plus generated protocol schemas and bindings.
- Fetch reminders in app-server only for a matching saved ChatGPT login. Return `notice: null` for ineligible, unavailable, or timed-out reads, and discard results when the login changes during the request.
- Route TUI reminder reads through the new method while retaining notice validation and identity checks. Unsupported servers produce no reminder.
## Testing
Add coverage for shared runtime use across restarts, ineligible authentication modes, and login changes during a fetch. Update TUI coverage for unavailable, unsupported, and mismatched notices.
GitOrigin-RevId: 426fee7ce98df17970957c06876881bc5b005196
## Why
Remote-control enrollment, refresh, and client-management requests used ChatGPT bearer authentication without resolving the configured runtime authentication mode.
## What changed
Pass the app server's runtime auth slot and mode into remote control, and resolve authentication and HTTP client policy for each request. Supported OpenAI destinations use fresh runtime assertions in `dual_header` or `assertion_only` mode, while custom destinations retain bearer authentication.
Wait for runtime authentication to initialize and reject unsupported OpenAI origins or mismatched registered accounts. Pairing continues to use its server token.
## Testing
Add transport and app-server integration coverage for both runtime auth modes, fresh assertions, shared runtime registration, network policy enforcement, account validation, redirect credential handling, and pairing token preservation.
GitOrigin-RevId: 5401cf565630ab84eaba71ff6040ac27f7b92461
## Why
Guardian Decisions requests used bearer keys directly, bypassing runtime authentication. Memory startup quota checks used the app-level auth manager instead of the thread's provider auth context.
## What changed
- Bind Decisions credentials to runtime authentication and use route-aware HTTP clients with sensitive header protection. Preserve workload identity credentials, reuse the saved-login runtime binding, and isolate explicit API key bindings.
- Select the staging Decisions endpoint when the ChatGPT environment is staging.
- Use the thread's `ProviderAuthContext` for memory startup and quota checks, preserving account-bound network policy and applying runtime authentication.
- Keep custom destinations independent of runtime assertions.
## Testing
Add regression tests for dual-header and assertion-only authentication, fresh Decisions assertions, saved versus explicit credential isolation, workload identity, staging routing, redirect header protection, and memory quota authentication with custom destinations.
GitOrigin-RevId: 27bc7821a1cad1f5d1d2a71680527ea91ace95db
## Why
Regular chats start MCP servers eagerly even when cached tool definitions are available and the servers go unused. Allow those chats to use the cached catalog and defer eligible stdio servers until first use.
## What changed
- Add the disabled-by-default `mcp_lazy_stdio_startup` feature and expose it through experimental feature configuration.
- Defer cached stdio servers in regular chats when enabled, while keeping servers that require a live startup connection eager. Required servers with `startup_readiness = "catalog"` may defer; explicit reconnects remain eager.
- Announce the full eager startup batch before terminal statuses and exclude dormant servers from the initial startup summary. Update TUI tracking so deferred servers can report startup independently in later rounds.
## Testing
Add scenario coverage for a cached server staying dormant during unrelated work, starting on first use, and refreshing tool definitions and visibility. Cover required live startup, eager event ordering, experimental feature configuration, and TUI status handling.
GitOrigin-RevId: 74075fcd4f26c8c79b5901b6a8cb03fdb9e35a7f
## What changed
Add a nullable `userId` to `GetAccountResponse`, populated from the same authenticated account snapshot as the rest of the response. ChatGPT and personal access token sessions return the canonical ChatGPT user ID when available; API-only and signed-out sessions return `null`.
Update the cloud client, generated schemas, TypeScript and Python types, and account identity documentation. Default missing IDs to `None` when deserializing responses from older app servers.
## Testing
Extend account response tests to check ChatGPT and personal access token user IDs, null IDs for other providers and signed-out sessions, and ID changes when switching providers with saved ChatGPT credentials.
GitOrigin-RevId: 7ad3da3cfc835c4d08d03c8e91b06cd7e007d874
## What changed
Make `TurnContextItem.permission_profile` required and remove its legacy `sandbox_policy` and `file_system_sandbox_policy` fields. Normalize older histories into a permission profile during deserialization, preserving the restrictive fallback for malformed filesystem rules.
Keep legacy compatibility fields in rollout serialization so older readers remain usable. Update turn recording, metadata extraction, and permission checks to consume the profile directly.
## Testing
Add coverage for legacy normalization, profile-only serialization, missing permissions, and malformed filesystem rules. Extend rollout round-trip fixtures to cover deny rules and filesystem roots from another platform.
GitOrigin-RevId: 27515fec60cccbac5806b98fb71f54e311a09701
## Why
A delayed file change approval cancellation could interrupt a later turn, even when the original approval was no longer pending.
## What changed
Send `Op::CancelPatchApproval` with the approval ID and requesting turn ID from the app server. Resolve cancellations only for a matching pending approval and interrupt its requesting turn only if it is still active. Route legacy `Op::PatchApproval` abort decisions through the same pending-approval handling.
## Testing
Add a regression test that cancels an approval, then replays that cancellation while a second turn has a pending approval with the same call ID. Verify that the second approval succeeds and its turn remains active.
GitOrigin-RevId: 4c833ccd0f33c2df4e9dfb25e2729ab19b6c879f
## What changed
Read `final_answer_moderation` metadata and attach `moderation: { moderated: boolean }` to the completed final-answer message only when its item ID matches. Apply this in both normal and plan modes, and reset the pending decision when a new response starts.
Preserve the answer's native item ID and moderation flag through legacy events and history reconstruction. Combine text parts into one legacy event when a moderation decision is present.
Expose nullable moderation data on app-server agent messages and update the JSON schemas, TypeScript types, and Python models.
## Testing
Add an integration test for moderation on completed answers and their legacy events. Extend protocol conversion tests to cover populated moderation data and serialization as `null` when absent.
GitOrigin-RevId: f286b67731a84b3daf5d10b7644f2e31b62f0e53
## Why
Queued inputs previously stored and dispatched without the submitting client's Responses API metadata, losing attribution such as `client_type` when the queued turn started.
## What changed
- Accept `responsesapiClientMetadata` when adding or updating queued submissions and expose it on returned queue items.
- Persist metadata with the input and forward it when starting a selected item or dispatching an idle queue, including after restoration.
- Preserve existing metadata when an update omits it or supplies an empty map; replace it when a non-empty map is supplied.
- Keep stored inputs readable by older queue workers and update generated protocol artifacts.
## Testing
Extend queue service and app-server tests to cover metadata round trips, preservation and replacement on edits, compatibility with older readers, and forwarding during selected, idle, and restored dispatch.
GitOrigin-RevId: 508043b1d3d0298c9af2be8e05b6999de46596a1
## Why
Runtime authentication must use the credential selected by the model provider. Explicit API keys and command credentials need independent ownership so cached connections and in-flight work cannot cross credential sources.
## What changed
- Register and reuse runtimes per credential source, supporting explicit provider keys and command credentials without falling back to saved login credentials.
- Track `AuthOwner` by credential manager and owner generation across WebSocket state, compaction, and scoring.
- Preserve cached identity and runtime registration state during credential-source outages or failed storage reloads. Require a successful auth reload before logout revokes credentials.
- Reject requests whose production or staging environment differs from runtime registration, including model catalog requests.
## Testing
Add regression coverage for credential selection and runtime reuse, owner isolation, source outages, failed reloads and logout recovery, and environment mismatches.
GitOrigin-RevId: 7bab55e0ea502593393df10046309fd8502edbd0
## Why
Gateway OAuth reads and logins previously used only the current provider, preventing clients from authorizing another configured provider without changing the default.
## What changed
- Add optional `modelProvider` params to `account/gatewayOAuth/read` and `account/gatewayOAuth/login`, preserving current-provider behavior for omitted or null params and selectors.
- Validate explicit providers against current managed policy without changing the default or any thread's provider.
- Retain readiness state across providers and send `account/gatewayOAuth/changed` notifications for every configured provider sharing the changed credential.
- Update protocol schemas, TypeScript types, Python models, and documentation.
## Testing
Add coverage for non-default provider login, retained readiness when alternating providers, notifications for shared credentials without starting login, and legacy TypeScript request compatibility.
GitOrigin-RevId: cfd472c322b821fe36b8c133a8de774f4ba48534
## Why
Item reads with an update boundary previously rejected forked thread histories and only supported an exclusive lower bound on update ordinals.
## What changed
- Add `before_updated_at_ordinal` as an exclusive upper bound, mutually exclusive with `after_updated_at_ordinal`.
- Allow update-filtered and update-ordered item reads across parent and child segments, applying segment bounds and preserving cursor pagination in both directions.
- Require an update boundary for update-order sorting and reject either boundary when using an item anchor or item-ID filtering.
## Testing
Extend thread-store tests to cover upper-bound filtering, descending cursor pagination, forward and backward paging across forked lineages, mutually exclusive boundaries, and ordinals outside SQLite's integer range.
GitOrigin-RevId: 63f7e18fb24a89a41ff8e570cf65963622519a25
## What changed
Allow `model_providers.<id>.gateway_oauth.credential_export` to supply a gateway access token instead of browser OAuth. Run the configured command on first use, cache its token in memory, and deliver it through the configured header or cookie. Export failures surface directly, and command-backed providers do not require an OAuth session.
Require mutually exclusive OAuth and exporter settings, same-origin model catalog access, and rejection of HTTP redirects for command-backed gateway credentials. Share the bounded, timeout-controlled command runner with AWS credential export.
## Testing
Add tests for inference and model listing without OAuth, token caching and recovery after invalid output, preservation of primary authentication, and rejection of mixed OAuth/exporter configuration.
GitOrigin-RevId: e3dbfd8823b1992045f1c1efd56ec98ee17e07a5
## Why
Clients need to list models for a configured provider other than the app-server's startup default.
## What changed
Add an optional `modelProvider` parameter to `model/list` and expose it in the generated schemas and client types. Explicit selections use provider definitions loaded at startup and respect current managed provider requirements. Unknown providers return a structured `modelProviderNotConfigured` error.
Use a temporary catalog when selecting another provider, preserving the default catalog and its disk cache while retaining runtime authentication. Requests without a selector keep the existing provider and caching behavior.
## Testing
Add coverage for provider selection, preservation of the default catalog and disk cache, unknown-provider errors, managed requirement enforcement, and runtime authentication for temporary catalogs.
GitOrigin-RevId: 6092df9f6141810c6ac215a8e1fb601f77e54747
## What changed
- Remove startup prefetching of remote catalogs, featured plugins, and recommendations while retaining installed-plugin refreshes and bundle downloads.
- Fetch featured plugin IDs on demand, concurrently with marketplace fetching when listing the remote global catalog, and reuse the cached results.
- Retire `plugin_discovery_prefetch` as an ignored compatibility flag and remove forced background catalog refreshes.
## Testing
Update app-server tests to verify that startup downloads installed bundles without discovery requests and that two `plugin/list` calls share one featured-plugin fetch.
GitOrigin-RevId: aa10474f3429102d624c83472e81ec85e3b470ae
## What changed
- Select fresh authentication for each HTTP operation on eligible OpenAI MCP connections while preserving the connection's credential source and account network policy. Stop redirects when requests carry runtime assertions.
- Pass the owning thread's authentication and runtime context through app discovery, connector metadata, and trusted-access requests. Include the runtime authentication mode in MCP connection and tool-cache identities.
- Give resumed actors analytics clients bound to their own authentication context, and serialize stored-credential reloads with token refresh while preserving host-provided credentials.
## Testing
Add coverage for fresh request assertions, revoked account policies, redirect handling, resumed-actor isolation, and MCP uploads in dual-header and assertion-only modes.
GitOrigin-RevId: f06900a6db61cd6cf53c3aa8075afeec4d5706d9
## What changed
Allow experimental clients to request `deferOutput: {"commandExecution": true}` in `thread/items/list` for a specific `turnId`. Completed commands with a recorded completion time, exit code zero, and nonempty saved output return `outputDeferred: true` and `item.aggregatedOutput: null`. Clients can retrieve the complete output through `thread/items/read` using the turn and item IDs.
Keep full output by default and for listings across turns. Make conversion from `ThreadItemEntry` to `ThreadItem` fallible so Rust consumers detect deferred output instead of treating an incomplete item as complete.
## Testing
Add integration coverage for experimental capability gating, default and disabled options, command status and output eligibility, listings across turns, deferred-item conversion, and full output retrieval by item ID.
GitOrigin-RevId: d6bfac34bb68f7e3b327fd5553270ed6d0fe87cf
## What changed
- Share the harness runtime identity with analytics delivery and turn-cost queries, and resolve request authentication together with its account-bound transport policy.
- Add runtime authentication to ChatGPT request helpers and `codex cloud`, including environment discovery. Resolve environment credentials for each request and honor CLI configuration overrides when loading cloud authentication.
- Preserve custom-backend authentication, validate runtime destinations, and keep cloud requests from following redirects.
- Forward only organization and project selectors from model-provider headers to API-key analytics requests.
## Testing
Add regression coverage for runtime request signing, credential refresh, account and resource selection, redirect credential handling, custom destinations, and cloud credential-store overrides.
GitOrigin-RevId: 75f33961ee6482881e9ff9817e99d977f31b65b8
## What changed
- Use the shared runtime and effective configuration for account API clients and remote plugin requests, including standalone plugin commands.
- Support dual-header and assertion-only authentication for remote plugins and MCP file uploads when runtime agent instances are enabled.
- Keep plugin credentials and caches scoped to the thread's account when resuming with different credentials. Bind request pools and multi-step plugin storage operations to the selected account so account replacement revokes stale operations.
- Protect runtime credentials on cross-origin redirects while preserving configured routing policies and legacy authentication for custom backends.
- Apply server-provided `upload_headers` to file storage uploads.
## Testing
Add coverage for shared runtime registration, both authentication modes, configuration reloads, resumed-thread account selection, account replacement during plugin uploads and downloads, and credential stripping on redirects. Extend file upload tests to verify runtime assertions and storage-only upload headers.
GitOrigin-RevId: 68aef81051a6f9bf919fffda52f372b108fce805
## What changed
Accept an optional `_meta` object on `mcpServer/resource/read` and forward it to MCP `resources/read`, including reads bound to an originating tool call. Update the protocol schemas and generated TypeScript and Python types.
Reject caller metadata containing host-owned `threadId`, `x-codex-turn-metadata`, or `codex/connectionLease` keys. For `codex_apps`, also reserve `connector_id`, `link_id`, and `_codex_apps.resource_uri` to preserve app and account routing.
## Testing
Add integration coverage for metadata forwarding through stdio, hosted app reads with and without a thread, and origin-bound widget reads. Cover rejection of reserved keys and non-object metadata.
GitOrigin-RevId: 227ee0fb5fe15fa2ff2ec66d4d5ae16de8935a8c
## Why
Changing the default model provider should not prevent users from resuming or continuing a thread that uses another configured provider.
## What changed
- Resolve cold resumes using the thread's saved provider and reject explicit attempts to switch it on resume.
- Use retained provider configuration for loaded threads without reloading the current default selection, while continuing to enforce managed provider policy.
- Preserve errors for missing provider definitions and policy conflicts.
## Testing
Update app-server and TUI coverage for resuming with a different default, recovering after restoring a missing provider definition, preserving drafts across resume retries, and continuing loaded threads with malformed system defaults.
GitOrigin-RevId: c5bf3b03cacde7349480c94c2f10bac827a0eb1f
## What changed
- Log `thread/items/list` request IDs, cursor kinds, page sizes, next-page availability, elapsed time, and success status.
- Log remote-control item-page response preparation and WebSocket write times, along with request and stream IDs, sequence IDs, frame counts, wire bytes, and success, interruption, or write-error outcomes. Collect these transport metrics only when debug logging is enabled.
GitOrigin-RevId: 0f26bef6d6b8cacbd5a5c76c49a5f882669f6598
## What changed
- Add `direct_only_tool_namespaces` to `TurnStartOptions`. Omission inherits the thread configuration; an empty list clears direct-only routing for that turn. Steering ignores the option.
- Persist explicit overrides in turn context and restore them when recovering an interrupted turn, including turns started by standalone tool output.
- Keep subsequent turns and spawned or resumed child agents on the thread's routing defaults.
## Testing
Add coverage for routing changes across turns in Responses and Responses Lite, recovery without carrying overrides into subsequent turns, and child-agent inheritance.
GitOrigin-RevId: cea1a997424572d4cd372cd15b098626904c6796
## What changed
- Expose `PromptCacheTtl` through `TurnStartOptions` and `RecoverTurnRequest`, supporting `30m` and `12h` minimum cache lifetimes.
- Carry the selected TTL through turn execution and compaction into `prompt_cache_options.ttl` on Responses HTTP and WebSocket requests. Omit the field when unset and keep the selection scoped to the turn.
- Include prompt cache options in WebSocket request reuse checks.
## Testing
Add coverage for both TTL values and omission on a subsequent turn without an override, and extend WebSocket serialization coverage to include prompt cache options.
GitOrigin-RevId: 8529306e6ad6030fe77c5e6bf19f3810717c0c5e
## Why
Core tests depend on `codex-app-server` to install and clean up agent message boards. A dedicated host crate lets them use this functionality without depending on the app server.
## What changed
Move the existing host implementation into `codex-agent-message-board-host` and update core test helpers and scenarios to use it directly. Keep the installation and deletion functions re-exported from `codex-app-server`.
GitOrigin-RevId: 9ed62d50a5f31c70550d70ba3c583399e869168a
## What changed
Add `ContextWindowId` as a string-backed protocol type with UUIDv7 generation and parsing. Use it throughout compaction state, rollout reconstruction, token budget context, and request metadata in place of raw UUIDs, preserving the serialized string format and UUIDv7 validation.
GitOrigin-RevId: 786b74fcc331707ca5d6765f429b6e5e322d9328
## Why
Direct executor skill discovery used unrestricted filesystem access, bypassing the turn's permission context. Cached catalogs also needed to account for changes in filesystem access within a turn.
## What changed
- Bind selected capability roots to callback-scoped filesystem access through `AccessedSelectedCapabilityRoot`.
- Pass accessors built with the turn's granted permissions into skill preparation and discovery, removing the executor skill provider's environment lookup and unrestricted accessor.
- Include filesystem access keys in the direct discovery cache so permission changes trigger rediscovery.
## Testing
Extend tests to verify that restricted discovery returns no skills when sandbox access is unavailable, restoring access restores discovery, and changing or restoring access invalidates the catalog cache.
GitOrigin-RevId: 0f7aa7646f65923f65f0cfc0b387d94bd7f2db05
## Why
Repository skill discovery must reflect current filesystem access, including newly approved grants and narrower permissions. Previously listed skills can remain in conversation history after a turn-scoped grant expires, so catalog updates need to tell the model when availability changes.
## What changed
- Discover repository skills through the selected executor's permission-aware filesystem accessor and refresh snapshots when the working directory or access changes. Use the current step's snapshot for skill selection and invocation.
- Preserve repository boundaries even when project markers are hidden by read restrictions, and report unsupported sandbox backends as skill-loading errors.
- Track grant-dependent catalog entries and emit availability notices when skills disappear or return, even when the metadata budget is exhausted.
- Resolve implicit skill paths through their owning filesystem and exclude remote repository skills from local implicit command attribution.
## Testing
Add coverage for turn and session grants, grant expiry and restoration, hidden and newly created repository markers, cached read denials on Windows, unsupported remote sandboxes, and executor-backed implicit skill paths.
GitOrigin-RevId: ac1af483e73e3130524aeeabe218630435054028
## Why
A model requirement can force `auto_review` even when the requested reviewer is `user`. Persisting or sending that effective value back as an explicit choice loses the original selection, so removing the requirement cannot restore it on resume.
## What changed
- Retain `requested_approvals_reviewer` separately from the effective reviewer in configuration and thread settings, with a fallback for older histories.
- Restore the requested reviewer on resume while applying current model requirements and reviewer allowlists.
- Let ordinary TUI turns, continuations, retries, and forks inherit the server's reviewer instead of echoing its effective value as an explicit request.
- Preserve a worker's requested reviewer when reloading it rather than inheriting the sender's selection.
## Testing
Extend resume coverage for explicit `auto_review`, removal of a model requirement, and a tightened reviewer allowlist. Update TUI assertions for omitted reviewer overrides and verify worker reload preserves its reviewer.
GitOrigin-RevId: d8c9c3a7b89e55e63f0e8ae210d6a87cb5547933
## Why
Reusable clients need fresh authentication for each request while preserving the credential source and transport policy selected when the client was created.
## What changed
- Add runtime-aware backend client construction and per-request authentication. Allow token refresh within the original credential source, reject credential replacement, and validate destination and account/organization selectors.
- Let runtime authentication finish persisting rotated tokens when the requesting task is cancelled.
- Apply asynchronous authentication to file creation and finalization requests, generating fresh assertions while keeping credentials off blob uploads.
- Preserve direct sandbox routing without enabling legacy custom-CA fallback for protected clients that reject redirects.
- Exclude login account metadata from model cache identities when provider bearer credentials override the login, and record authentication selection outcomes and duration.
## Testing
Add regression coverage for credential refresh and replacement, organization selection, destination restrictions, transport policy preservation, cancellation during token rotation, credential stripping on redirects, and file upload authentication in both runtime authentication modes.
GitOrigin-RevId: d045595e869dfcdfd9f705a6228cf0eb4c2d2c12
## What changed
- Share a lazily registered runtime across threads, model discovery, and extension clients when `runtime_agent_instances` is enabled, while honoring each thread's authentication mode and credential owner.
- Bind model catalogs to the effective provider and authentication context while preserving cache policy and live API-key discovery settings.
- Resolve credentials, routing, and transport policy together for each request. Preserve proxy and TLS settings, validate runtime account selectors, and prevent pooled connections from crossing runtime identities.
- Accept supported ChatGPT subdomains when selecting the registration environment.
## Testing
Add integration coverage for shared runtime registration, dual-header and assertion-only modes, disabled and third-party providers, credential replacement, subagents, and delegated review. Add coverage for catalog cache policy and runtime-aware connection reuse.
GitOrigin-RevId: 99dd9d987c29c93597a648f6586f98ac6a932c3c
## What changed
Move permanent agent message board deletion from `codex-core` into the app server's thread-store cleanup callback. Keep board cleanup active when the board feature is disabled, and run it before optional Guardian evidence-board cleanup.
Remove the message board extension dependency from `codex-core` and retain `codex-message-board` only as a development dependency. Update the core test harness to install the app server's cleanup callback.
GitOrigin-RevId: 61813bbdcd8b57073b8c249e1f771e3fb0ea061e
## What changed
Move the board host adapter and `install_agent_message_board` from `codex-core` to `codex-app-server`, using public core runtime interfaces. Update extension registration, test callers, dependencies, and installation documentation to use the new location.
Format `CHANNEL_POST` notification payloads in the host adapter and retain recognition of legacy board notices in core. Expose `MULTI_AGENT_V2_NAMESPACE_DESCRIPTION` for host extensions to share with native tools.
GitOrigin-RevId: 679b5751de102bff80e6b9d4b0728a84fbdedd85
## Why
Existing chats can retain reasoning effort and service tier selections that a refreshed provider catalog no longer supports.
## What changed
- Apply fresh provider catalogs to saved settings in open and resumed chats, and normalize incoming settings before capturing the next turn.
- Replace unsupported ranked reasoning efforts with the highest supported level at or below the selection. For unsupported `ultra` or `persistent` selections, use the model's supported default when available. Reset unsupported `priority` and `ultrafast` service tiers to `default`.
- Retire incompatible reasoning effort pins using each step's captured model metadata, preserving running steps and the live pin during compaction.
- Publish catalog updates only from successful provider responses for the current identity, and refresh retained originator catalogs through the periodic refresh worker.
## Testing
Add coverage for setting correction, reasoning effort pins, resumed chats, stale queued settings, retained history, refresh failures, identity changes, and isolated originator notifications.
GitOrigin-RevId: 2ef4605c4acba98db3fe9d0328e2752084e900a2
## What changed
Add optional `contentTokenCount` metadata to `item/completed` notifications, carrying the producer-supplied token count for each completed assistant message in default and plan modes. Counts include any sampled footer and are `null` when unavailable.
Keep this telemetry separate from stored thread items and omit it from subsequent model requests. Update the protocol schemas and generated TypeScript and Python types.
## Testing
Add coverage for per-message counts, including zero, in default and plan modes; missing and malformed metadata; backward-compatible notification decoding; and exclusion from subsequent model requests.
GitOrigin-RevId: 35973037a42650fa2d7569da8e88cb81215cf971
## What changed
- Add optional `ModelInfo.web_search_provider` metadata with `standalone` and `search_mcp` values.
- Add `tools.client_search_provider` and expose its value as `client_search_provider` in app-server configuration responses, with updated JSON schemas, TypeScript types, and Python bindings.
- Register the `hosted_search_policy` feature flag as under development and disabled by default.
GitOrigin-RevId: 263c3f81a61b50f8bb53ff338b9de8186db316e0
## Why
SQLx's SQLite migration lock is a no-op, allowing concurrent database openers to race between schema version checks and migration changes.
## What changed
Run schema checks and migrations in one transaction, retrying SQLite busy errors from a fresh snapshot. Databases with a current schema need only a read lock, including on NFS. Include the error cause chain when the app server reports SQLite initialization failures.
## Testing
Add regression tests for eight concurrent database openers applying each migration once and for reopening a current schema while another connection holds a writer reservation with NFS settings.
GitOrigin-RevId: 38004d58a5c637ac1b2be53d07fd9a4c8efec7ab
## What changed
Register Guardian evidence-board cleanup with the app server's thread store when Guardian V3 is enabled. Leave Guardian storage untouched when the feature is disabled, and report cleanup failures as thread-store errors.
## Testing
Extend deletion tests to cover feature gating, preservation of unrelated boards and a surviving main thread's board, and corrupt-database recovery. Expand message-board tests to verify namespace isolation and persistent deletion markers that prevent later writes.
GitOrigin-RevId: d9119d22607769c92448d0f3cacbbfd03fbdf943
## What changed
Replace `thread_store_from_config` with `ThreadStoreBuilder`, exported through `codex_core` and `codex_core_api`, and migrate callers to the builder.
Allow hosts to register `with_additional_cleanup` for permanent deletion in local stores. The callback runs after successful agent-board cleanup and before rollout deletion, under the existing deletion locks. Document that cleanup must be idempotent and must avoid thread-store operations that reacquire those locks. In-memory stores do not invoke the callback.
Preserve the existing backend selection, startup rollout migration, and compression behavior.
GitOrigin-RevId: f2853d7de06fe12ef29451b204cf9fcbb349c359
## Why
After provider setup, new threads could still use the models manager created for the server's startup provider, leaving their default model inconsistent with the model picker.
## What changed
- Build a models manager from the thread's configuration when its provider differs from the startup provider.
- Invalidate the model catalog after successful Amazon Bedrock setup so subsequent model listings reflect the configured provider.
## Testing
Extend Bedrock and GCP setup integration tests to verify that a new thread's model matches the refreshed model listing. The Bedrock test also checks that the thread uses `amazon-bedrock`.

## What changed
- Add `currentAccountOnly` to `thread/list` and `thread/search`, defaulting to `false`, and enable it for TUI history discovery, resume pickers, and task mentions.
- Mark newly created threads as account-scoped and require each recorded creator user or account ID to match the current login. Older threads and threads without creator IDs remain shared; API-key logins continue to see all local history.
- Preserve account scope through resume and revert, including fallback to original rollout metadata when an older binary drops the marker. Forks receive new-thread scope.
- Skip unreadable rollout headers in scoped discovery and filter search candidates before reading snippets. Direct access by thread ID remains available.
## Testing
Add coverage for account matching, shared legacy history, list page refilling, search pagination, API-key visibility, and scope preservation across reverts. Extend rollout lookup coverage to compressed active and archived files.

## What changed
Add the disabled-by-default `cli_resume_account_check` feature. When enabled for `codex-tui` and `codex_exec`, reject resuming or attaching to a local thread if its recorded creator user or workspace differs from the current ChatGPT account. Return an error directing the user to sign in with the original account.
Carry creator IDs through stored thread metadata and check them before loading resume history. Preserve existing behavior for untagged threads, other clients, and authentication modes without a comparable ChatGPT account.
## Testing
Add integration coverage for account and workspace mismatches, matching accounts, legacy and paginated history, ID and path lookup, and the feature's default and bypass behavior. Verify that switching back to the original account permits attachment to a loaded thread and that creator metadata remains unchanged.

## What changed
Add `modelProvider/config/write` to create custom gateways and patch existing custom gateway, Bedrock, and GCP settings. Return the saved provider using the same safe summary as `modelProvider/list`.
Omitted fields retain their values; explicit `null` clears nullable user overrides. Apply patches through the shared configuration queue with last-write-wins semantics, enforce field editability and validation, and preserve unexposed authentication settings.
Saving leaves provider selection and authentication unchanged. Saving the provider used by `model/list` invalidates its catalog for the next access. Include documentation and generated JSON, TypeScript, and Python protocol types.
## Testing
Add coverage for gateway creation and ID allocation, patch and null semantics, configuration policy enforcement, authentication preservation, and catalog refresh after active-provider edits. Extend Python protocol tests to verify wire round trips and reject mismatched provider IDs or fields.

## What changed
- Add `modelProvider/list` to return OpenAI and explicitly configured providers, provider-specific settings, and the selected default provider.
- Report `canEdit` and `canChangeDefault` based on configuration requirements, layer precedence, and whether user configuration is enabled.
- Describe gateway authentication without resolving credentials, and omit endpoint URLs that are unsuitable for display.
- Document the API and update generated JSON schemas, TypeScript types, and Python models.
## Testing
Add app-server tests for provider discovery, authentication modes, unsafe URL suppression, and configuration editability, plus a Python wire-format round-trip test.

## Why
`start_or_steer_turn` rejected agent messages, preventing callers from submitting follow-up work through the turn input API.
## What changed
Route `TurnInput::InterAgentCommunication` through native agent message delivery and return `TurnInputSubmission::Accepted`, without implying an immediate turn ID. These submissions request work regardless of `trigger_turn`, retain the recipient's settings, and forward turn-start options.
Wrap plaintext messages with agent context while preserving encrypted content. Reject submissions to idle recipients when the host is draining.
## Testing
Add scenario tests and snapshots covering queued-message ordering, encrypted follow-ups, preemption at reasoning boundaries, and follow-ups arriving before or after a final answer. Extend drain-gate coverage to agent submissions with parent-turn lineage.

## Why
Live paginated history retains completed assistant text even when summaries only need the latest message. Release older text for threads with persisted history while preserving full resume responses.
## What changed
- Evict superseded assistant text from live turn state while preserving corrected items and the latest assistant message.
- Restore evicted text for full resume responses from prepared history pages, fetching remaining items by ID in bounded batches. Return an error if saved text is missing.
- Only load the active turn when it belongs in the requested initial page, and use the item ID index for targeted history reads.
## Testing
Add reducer coverage for text eviction and corrected messages. Extend running-thread resume coverage to compare full and summary items with live notifications, exercise restoration when the prepared page lacks the active turn, and check missing-text errors.

## What changed
Allow connector-wide app settings under `plugins.<plugin>.apps.<connector>` for plugins enabled by configuration. Merge these settings field by field, giving earlier plugin names precedence and applying explicit top-level `apps` fields last. Ignore nested `_default` settings.
Expose the merged app settings and their field origins through the config API. Keep app policy changes from invalidating the loaded-plugin cache.
## Testing
Add coverage for plugin enablement, merge precedence, field origins, config API output, cache reuse, and disabling an app through plugin configuration during explicit plugin mentions.

## Why
Clients need to refresh section membership and ordering when another client moves a thread.
## What changed
Broadcast `thread/section/changed` after a successful `thread/section/move`, including moves within the same section. Send the response before the notification, and include `threadId` and the destination `sectionId`, using `null` for removal. Failed moves do not emit the notification.
Add the notification to the protocol schemas, TypeScript exports, and Python SDK models and registry, and document its behavior.
## Testing
Add a WebSocket integration test with separate writer and observer clients covering section insertion, reordering, removal, and a failed move.
