## What changed
Allow `requirements.toml` to pin `features.runtime_agent_instances.mode` to `dual_header` or `assertion_only`. Apply the required mode when no explicit mode is configured and reject conflicting explicit settings, while preserving legacy boolean requirements.
Document experimental runtime authentication configuration, credential lifecycle, and bootstrap authentication behavior.
## Testing
Add coverage for managed mode defaults and conflicts, runtime reuse and rotation across account requests and restarts, fresh assertions on Realtime and MCP reconnects, and Realtime destination and environment restrictions.
GitOrigin-RevId: bcf9502178f477c1e8232386f1f3e360bf23d667
## 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
## Why
Realtime connections bypassed runtime authentication and reused captured authentication headers for sideband handshakes. They need to honor the selected credential source and its transport policy across call creation, retries, and reconnects.
## What changed
- Use runtime authentication for realtime WebSocket connections, WebRTC call creation, and sideband attachment when enabled for supported OpenAI destinations.
- Resolve authentication on every WebSocket handshake, preserving credential ownership and request scope while generating fresh assertions. Reject authentication failures without falling back to bearer authentication.
- Keep call creation and sideband attachment bound to the selected credentials and account network policy, including when inference uses a different provider.
- Avoid runtime initialization for local marketplace and MCP operations, plugin commands that do not use the remote catalog, and model debugging with a configured catalog.
## Testing
Add coverage for fresh handshake credentials on retries and reconnects, credential and account changes, runtime authentication modes, destination validation, and registration failures.
GitOrigin-RevId: 57e53122912fa78a524427b0f51013f76f9f7681
## 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
## What changed
Refocus `openai-docs` on Codex and ChatGPT Work behavior and first-time API integrations. Skip API questions about existing integrations, action requests, and tasks fully answered by supplied text or data. Retain model migration guidance when users explicitly invoke `$openai-docs`.
Replace the broad routing workflow with guidance to check available tools and settings, consult documentation for the relevant product surface, and verify recent changes through the changelog and linked client changes or tests.
Update the skill's display metadata and affected skill catalog snapshots to match.
GitOrigin-RevId: 0a0e9abbee9975ebd30917b7477f475096f2c86b
## 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
## Why
Switching away from a model that requires automatic review should restore the user's requested approval reviewer instead of retaining the model's enforced reviewer.
## What changed
Recompute the reviewer from the requested preference and model requirements when the model changes without an explicit reviewer update, unless the session uses a trusted guardian reviewer. Preserve an explicit automatic-review preference across subsequent model switches.
## Testing
Extend the app-server settings regression test to cover restoring user review after leaving a protected model and retaining an explicit automatic-review choice across repeated model switches.
GitOrigin-RevId: a5672d1ebe94c2fac201ad460b4789d11df03b1a
## 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
Cached gateway command credentials need to be refreshed when the gateway rejects them with a `401`.
## What changed
Clear the cached `credential_export` token after an inference HTTP `401` or a WebSocket upgrade rejected with `401`, then rerun the command for one retry. Preserve subsequent primary authentication recovery if the retry is also unauthorized, and document the behavior.
## Testing
Add integration coverage for using a new exported token, reporting an invalid export, recovering primary authentication after the gateway retry, and stopping after a second unauthorized WebSocket upgrade.
GitOrigin-RevId: 3397476dbfd3bec1bd44f90657c4f9e17bb7df67
## 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
## Why
Matches in parent directory names can crowd matching filenames out of limited search results. For example, searching for `ViewModel` should keep `ChatViewModel.kt` visible even when many directories are named `viewmodel`.
## What changed
- Rank basename matches before applying the result limit for single positive fuzzy queries without path separators.
- Prefer exact filenames, then the strongest exact directory match, then other matching filenames. Leave additional directory matches ranked by their paths.
- Compute highlight indices from the basename for promoted results and return scores that reflect the new ranking.
- Rank snapshots in resumable time slices so new queries and cancellation can interrupt the work.
## Testing
Add regression coverage for filename matches surviving the result limit, exact file and directory priority, path queries, and resuming partial rankings. Update app-server score expectations while preserving highlight indices.
GitOrigin-RevId: 41b3420581b4f6490859e809245370b737889544
## Why
Guardian scoring and cached approvals need to use the requesting turn's captured policy even when the live thread configuration changes. Newly tightened mandatory review requirements must still prevent cached approvals.
## What changed
- Pass captured turn configuration through tool lifecycle and approval review inputs, and use it to resolve Guardian policy and classifier instructions.
- Apply current reviewer and model requirements before scoring and cached approval, including rechecking restrictions after collecting score authorization.
- Count computer-use JavaScript execution attempts even when background scoring is disabled, so a synchronous call consumes the initial-call allowance.
- Retain runtime configuration snapshots when applying agent role overrides, and share Guardian policy text resolution between configuration loading and runtime publication.
## Testing
Add and extend regression coverage for captured policy instructions, reviewer restrictions, stale cached evidence, and a synchronous computer-use call followed by an adaptive turn.
GitOrigin-RevId: 24ed4a1b6ce1733ad775790f30e440da614f9cd6
## 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
- Add `--chatgpt-token-stdin` for remote HTTPS registration and optional `--chatgpt-account-id`, which must match the token's account claim when present. Read a bounded, newline-terminated token from a pipe without persisting it to `auth.json`.
- Load managed configuration using the supplied account, enforce account restrictions, and preserve configured policy-server authentication. Skip ChatGPT policy lookup only for known plans that do not require managed configuration.
- Allow `--exit-on-stdin-close` to cancel pending policy loading, and redact the registration bearer from registry diagnostics.
- Reject incompatible stdin credential options, including flags placed on opposite sides of `forward`, and disallow ChatGPT token stdin authentication with `forward`.
## Testing
Add coverage for account-claim validation, policy selection, policy-server sign-in requirements, shutdown during policy loading, credential flag conflicts, and bearer redaction.
GitOrigin-RevId: b6b50565e1f150b96edf3cee796909a991f1b47f
## 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
## Why
Agent messages that arrive after a model request starts must survive compaction until a normal inference request includes them. Compactor output alone does not establish that those messages were delivered.
## What changed
- Persist history sequences and sampling checkpoints in harness metadata, capturing the input prefix for each normal inference request.
- Retain pending agent messages within existing size budgets during local and remote compaction, placing the summary before pending messages and subsequent caller input.
- Preserve sampling progress across history replacement and resume, and drain queued mail after interrupted sampling even when compaction leaves context above the token limit.
## Testing
Add regression coverage for request-boundary sampling checkpoints, pending messages across local compaction and repeated remote compaction with resume, and injected messages that interrupt sampling before mid-turn compaction.
GitOrigin-RevId: 26c04ab96b5a1c3cc1d6625ccc74a0f00201d14c
## Why
Tests need to distinguish slow subprocess startup from operation timeouts and wait for asynchronous work before asserting results or cleaning up fixtures.
## What changed
- Synchronize subprocess readiness, queued-turn completion, and matching UI events; allow more time for cold startup and separate startup from shutdown deadlines.
- Adapt Windows fixtures and permission expectations, provide the voice-host test runtime DLL path, and normalize platform paths and animated status snapshots.
- Use current configuration permissions when changing directories in embedded TUI sessions, while retaining saved permissions for remote sessions.
- Allow the release prompt-prefix comparison to accept the exact image-tool description update that removes image detail options, and refresh the corresponding tool snapshot.
## Testing
Extend inherited-session metadata coverage to both legacy and paginated thread history, including persisted history mode and revision-aware resume.
GitOrigin-RevId: 0afb38403fc0adb0d83175344749584f0cdf9979
## 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
## What changed
Mark `unified_image_budget` stable and enable it by default. Supported models now use unified image preparation with `original` detail, and `view_image` omits the `detail` parameter from its advertised schema.
## Testing
Update image input, MCP output, history replay, and tool schema expectations for the new default. Keep explicit coverage of the disabled feature and models that do not support original image detail.
GitOrigin-RevId: 2d6fc8019149fcf18b5813db2d2082ba95de2241
## 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
## What changed
Track Guardian compaction and review turn execution within each tool's auto-review interval, and expose `critical_path_auto_review_overhead_ms` in turn analytics. This measures the portion of `auto_review_ms` outside observed Guardian turn execution; it is a subset, not an additional duration.
Freeze review observations when the review or tool invocation ends. Report unknown overhead as `null`, including when denial reconsideration runs an unobserved follow-up turn.
## Testing
Add coverage for shared compaction and review observations, cached reviews, unfinished reviews, reused tool call IDs, and execution timing with child critical-path capture enabled or disabled. Extend analytics and app-server tests to check the new field.
GitOrigin-RevId: a63dec2a75571a3167c8c3f0c1d21e11e4a8d050
## 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
- Report sampling and compaction separately as `critical_path_sampling_ms` and `critical_path_compaction_ms`, retaining `critical_path_inference_ms` as their combined compatibility total.
- Enable critical path capture for subagent and Guardian turns when `CriticalPathTiming` is enabled, while continuing to exclude memory consolidation sessions.
- Preserve capture across incoming agent messages and support direct `spawn_agent` and `wait_agent` calls. Attribute these calls to the parent's tool time and keep child work on the child's own turn.
## Testing
Add runtime coverage for independent parent/child timing, incoming agent messages, Guardian turns, feature gating, and memory consolidation exclusion. Update phase accounting and analytics tests to cover the new fields and millisecond truncation.
GitOrigin-RevId: 09d4c0b853e817216bed173e4404d0d782de97ec
## 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.

## 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.

## 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.

## What changed
- Gate GIF output behind `features.image_generation_animation`, disabled by default.
- Accept `gif` options for generation and editing, with optional `frame_count` and `frame_duration_ms` controls. Use `gif: {}` for API defaults.
- Preserve animated output with `.gif` filenames and `image/gif` data URLs while providing a still preview to the model.
- Add guidance for simple animations and spritesheet-based GIF edits.
## Testing
Add integration coverage for GIF generation and editing, explicit frame controls and API defaults, saved animation bytes, and still-preview replay across follow-up turns.

## 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.

## Why
Search discovery must account for the active model's supported tools while honoring host search restrictions. Automatic fallback must also preserve the provider that owns existing browsing references.
## What changed
- Resolve search from model metadata, client configuration, and managed requirements, exposing the selected provider's tools.
- Discover hosted search with the model's supported tools and carry the discovered invocation context into calls.
- Allow native fallback for eligible discovery failures only when search policy permits it and hosted search has not already been used. Do not replay failed hosted invocations through native search.
- Keep native fallback references on native search across later turns, discovery recovery, and resume. Release unused fallback offers and coordinate background calls to prevent conflicting provider use.
## Testing
Add app-server and core scenario coverage for provider selection, discovery failures, search restrictions, reference continuity, resume, and concurrent background search. Include a snapshot covering discovery and call history across a model switch.

## 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.

## 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.

## Why
A fork's inherited history can become unreadable when the preferred ancestor rollout is truncated or has an incomplete compressed frame, even when a usable archived copy exists.
## What changed
- Retry failed ancestor reads using another copy of the same rollout, validating its owner and location before rebuilding the lineage.
- Apply fallback to model-context loading, fork and revert preparation, and paginated history reads. Preserve the original error when no usable replacement exists.
- Validate inherited byte offsets when opening ancestors for consumption, allowing a newer model-context checkpoint to avoid reading an unusable ancestor.
- Limit ancestor materialization to the inherited history boundary while preserving any existing progress beyond it.
## Testing
Add regression coverage for incomplete compressed ancestors, replacement ownership checks, archived-copy recovery during resume and fork, and materialization boundaries. Add an app-server test that cold-resumes a fork and pages inherited turns and items from an archived copy when the active ancestor is too short.
