## Why
Truncating verified answers can obscure the association between questions and responses. Elastic entry caps must preserve that association.
## What changed
Mark verified answer records in root conversation and trusted user answer sections so elastic preparation keeps them intact when they fit. Replace oversized records with the protected incomplete-answer notice and record zero retained evidence bytes.
## Testing
Add a regression test with two questions and opposite answers, checking that both evidence sections omit oversized records whole and preserve complete records when the entry cap allows them.

## 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
## Why
A reviewer receiving retained REPL responses after compaction can exhaust its context budget on protected response headers alone when the store contains many small results.
## What changed
Select a contiguous suffix of the newest responses before allocating body budgets, bounding elastic selection by the token-derived cost of provenance headers and separators. Preserve retained response bodies and images for subsequent allocation, and include dropped responses in the omission count. Apply this selection to both text-only and multimodal evidence.
## Testing
Extend the elastic REPL regression test with 10,000 responses in both evidence modes, checking budget admission, contiguous newest-response retention, preserved text and images, and combined storage and selection omission counts.
GitOrigin-RevId: 47c10d2f50e863ce4ba186be888788b8be5299dc
## 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
Incremental tool declarations were limited to Responses Lite. Regular OpenAI Responses requests sent the full current tool catalog on each request.
## What changed
- Add the disabled-by-default `incremental_tools_legacy` feature for regular OpenAI Responses, independently of the Responses Lite `incremental_tools` flag.
- Support tool declarations and updates in conversation history, including during compaction, while preserving existing history prefixes.
- Keep hosted `web_search` configuration in top-level `tools` rather than `additional_tools`, including in compaction requests.
## Testing
Extend request-history scenarios and snapshots to cover regular Responses catalog updates, model switches, compaction, and MCP tool removal and restoration. Assert that incremental requests preserve input prefixes and keep web search out of history declarations.
GitOrigin-RevId: fa347409e387aa973ce2e41df8505769b7db1ec2
## What changed
- Register an additional Cloud connection on supported macOS and Linux launches when `TuiMultiBackend` is enabled, using the selected ChatGPT account and local network policy.
- Preserve backend settings and identify Cloud in connection controls and status.
- Let Cloud supply the model when a thread opens, skip local skills requests and stale results, and allow resume without a local working-directory override.
- Preserve Git metadata in Cloud thread snapshots and continue history hydration past empty filtered pages within the scan budget.
- Report Cloud connection failures and require reopening Codex to reconnect.
## Testing
Add regression coverage for Cloud model bootstrap, skipped skills requests, resume directory handling, history pagination through filtered pages, and Git metadata preservation.
GitOrigin-RevId: 6717f0f5ad7708c5e9b5796d94711dd1eecc49bb
## 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
Sidebar resizing previously required an open side chat, leaving the chooser without the same width controls.
## What changed
- Support keyboard resizing, width presets, and divider dragging for the sidebar chooser, with resize hints that fit narrow sidebars.
- Keep keyboard resize mode active across startup thread assignment and replacement of the chooser by a new side chat, so `Enter` finishes resizing without submitting the parent draft.
- Activate resize bindings only when a split is available, and prevent divider drags from starting while the split is animating.
## Testing
Add regression coverage for chooser resizing, width preservation when switching between the chooser and a chat, startup and side-chat creation transitions, draft preservation, and unavailable resize bindings in narrow terminals.
GitOrigin-RevId: 511cd4bb5894e6f33f0cf5d7472bb3013361ffe0
## 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 sign-in needs an alternative for terminals that cannot open a browser.
## What changed
- Add optional `gateway_oauth.device_authorization_url` configuration and a `login_with_device_code` API that presents a verification URL and user code, polls for approval, and persists the resulting credentials.
- Use the configured proxy and network policy, validate verification URLs, and bound OAuth responses. Support cancellation and report denied or expired codes without exposing issuer error details.
## Testing
Add tests for successful authorization and credential persistence, unsafe verification URLs, network-policy denials, denied and expired codes, and cancellation during approval or credential storage.
GitOrigin-RevId: 96398578fb866d34929e85c04eadf468d8cd3255
## 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
The TUI's cached active turn can be stale when a cloud message is submitted. A lost reply also leaves delivery uncertain, so automatically resending the draft risks submitting it twice.
## What changed
- Let the cloud server choose whether an Enter submission starts or steers a turn, and apply its receipt to the matching client message ID.
- Keep Tab-queued input waiting until the admitted turn finishes, including before its start notification arrives.
- Restore rejected submissions to the composer. Hold duplicate or unconfirmed submissions out of automatic delivery until history confirms them.
- Reconcile saved drafts and pending steers by client message ID when resuming sessions, and preserve submissions belonging to other turns during interruption recovery.
- Classify cloud preflight failures as invalid parameters so rejected queued input can be restored safely.
## Testing
Add regression coverage for cloud receipt outcomes, queued-input ordering, rejected drafts, lost replies, interruption recovery, and session resume with identical message text but distinct client IDs.
GitOrigin-RevId: ec4eb581e450488434bc4614ec59273d73ffd0a1
## 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
## What changed
Add an optional `thread_id` to `HostedFileUploadContext` and include it as `codex_thread_id` in file creation requests when provided. Keep MCP app uploads without this field while retaining the thread ID in tool-call metadata.
## Testing
Extend upload tests to check inclusion and omission of `codex_thread_id`, and assert that MCP app calls retain `_meta.threadId` without adding it to file uploads.
GitOrigin-RevId: cff15b35e5130e56973f944b3b849807550d298b
## What changed
Add a default `ModelRequestContributor::budget_exhausted` hook and fail generation with `SessionBudgetExceeded` when any contributor reports an exhausted budget for the thread.
Check budgets before HTTP requests and before WebSocket connection setup, then check again after the connection is established. WebSocket warmup remains available when the budget is exhausted.
## Testing
Add coverage for budget changes during a tool call, verifying that exhaustion prevents the next model request while an available budget allows completion. Extend WebSocket coverage to verify that exhausted generation opens no connection and warmup still permits connection reuse once the budget becomes available.
GitOrigin-RevId: 97ce02dc7f9bd54830e4b73c4f0334a30367eebf
## 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
Move proxy configuration and routing selection into `prepare_managed_network`. Keep native Windows launches direct by stripping managed proxy variables before credential brokering, and select dedicated listeners only for Windows MXC launches.
Consolidate managed network context filtering in `SandboxManager` and simplify proxy preparation for Linux and MXC while preserving the macOS Seatbelt context.
## Testing
Add Windows regression coverage for native launches with both disabled and enabled proxy configurations, verifying that managed proxy variables are removed while caller environment values and API credentials are preserved.
GitOrigin-RevId: 29fe1fb02afb574b4108032b7e8028d19d8270b4
## Why
Incoming delegated messages were rendered as plain text, leaving Markdown formatting visible and links without hyperlink metadata.
## What changed
Use a dedicated history cell to render the message body as Markdown while keeping the source task attribution literal. Preserve hyperlinks and wrapping, and apply the appropriate list spacing for scrollback and the redrawable transcript.
Use the same rendering for live messages, resumed history, and transcript projection.
## Testing
Extend replay coverage to check matching live and replayed output, transcript rendering, hyperlink destinations, and shared source text across wrapped rows. Add a snapshot covering list spacing in scrollback and the redrawable transcript.
GitOrigin-RevId: e9864c7721fa1afa2d3662ab9f57122ab696a51e
## 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
A message's model-visible item ID may be unknown until the recipient records it. Message lifecycle observers need to capture publication state before that point.
## What changed
Remove `message_id` from `MessageLifecycleInput` and give each publication's `ExtensionData` a fresh UUID key. Stop assigning an item ID when publishing messages for lifecycle observers.
## Testing
Update the agent mailbox test to store a contributor-specific token in `ExtensionData` at publication and retrieve it at consumption, verifying that publication state survives queued delivery and recipient eviction.
GitOrigin-RevId: e254f94994d0976e61cb46ee23297f3248b9a389
## What changed
- When side retention is enabled, let the sidebar chooser create additional side chats from the main chat or reopen existing ones.
- Add numbered, clickable tabs and keyboard navigation in the chooser. Keep the selected tab visible when space is limited.
- Preserve drafts, transcript history, and the sidebar layout when switching between sibling side chats.
- Make `/side` with a prompt request a new side chat, while `/side` without arguments reopens the selected side chat. Preserve existing reuse behavior when side retention is disabled.
## Testing
Extend TUI tests and snapshots to cover creating sibling side chats, switching through the chooser and tabs, retaining drafts and history, and restoring image attachments after failed creation.
GitOrigin-RevId: 4166010c253c40a409390f7020b69478c04cf98c
## Why
Some hosts assign a worker per connection. Idle connection eviction can prevent a quiet session from reaching the worker holding its lease, while retaining a connection after the last session closes unnecessarily keeps that worker allocated.
## What changed
- Disable the HTTP connection pool idle timeout for gRPC code-mode connections.
- Cache URL-based clients weakly and let live sessions own the shared client, releasing their ownership on closure or failure even while the provider remains alive.
- Acquire clients for deferred RPCs only when needed and return the session error if the client has already been released.
## Testing
Add regression tests that verify connection reuse and stored state after 120 seconds of inactivity, and connection closure after the last shared session fails while the provider and session handles remain alive.
GitOrigin-RevId: bd1ff00c4003c03ed173c23dd2ed373ed354ab65
## What changed
- Add an “Add custom provider” entry to the provider picker and an “Edit configuration” action for editable providers.
- Provide forms for custom gateway names, base URLs, and API key environment variable names, plus supported Bedrock and GCP settings.
- Validate required fields, suggest environment variable names from the provider catalog, and preserve drafts when validation or saving fails.
- Save configuration through the connected app server, write only changed fields, and refresh the provider list after saving. For uncertain creation results, ask users to check the list before adding the provider again.
## Testing
Add editor tests for validation, draft recovery, Vim input, and patches that preserve unchanged authentication settings. Add an integration test covering the edit action and custom provider creation while preserving the default provider, with snapshots of the new UI.
GitOrigin-RevId: 8eb32ed30ed27ab671f08f565af48705f2b9f193
## What changed
- Add `accepted_at_unix_ms` and `accepted_seq` to conversation items, recording the first local `HistoryItemAccepted` event in trace order. Inherited context alone does not count as local acceptance.
- Add `started_code_cell_id` to model-requested `exec` tool calls when a matching code cell exists in the same thread and, when known, turn. Resolve links after replay so deferred cell starts can be matched.
- Default the new optional fields to absent when deserializing older traces and omit them from serialized output when unset.
## Testing
Extend reducer tests to cover duplicate acceptance events with out-of-order clock readings, inherited items without local acceptance, and `exec` calls with and without matching code cells.
GitOrigin-RevId: dfb594630f77d7c899398aa181c88a681587b1df
## 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
Update Seatbelt tests to call `create_seatbelt_command_args` directly with explicit filesystem and network policies, and remove the unused legacy-policy wrapper.
Reuse `FileSystemSandboxPolicy::read_only()` in read-only policy conversion and test setup instead of constructing equivalent policies inline or through legacy conversion.
GitOrigin-RevId: 2e2b3342425a3477986f41135caa18003b697fe4
## What changed
Remove `FileSystemSandboxContext::from_legacy_sandbox_policy` and migrate its test callers to `from_permission_profile`. Construct read-only, disabled, and externally enforced sandbox contexts directly with `PermissionProfile`.
GitOrigin-RevId: e330b89d060061eda106232eab554be5ccd06149
## What changed
- Expose an optional `AgentServiceTier` provider so host-owned children, including detached children, inherit the root's committed tier during spawn preparation, startup prewarm, and each inference step.
- Reject per-turn tier overrides for children using the shared provider. Root updates apply to subsequent requests without changing requests already in flight.
- Preserve independent configured tiers and role overrides when no provider is installed, including across eviction and reload. Spawned children inherit the parent's thread preference rather than its per-turn override.
- Publish the latest committed root tier only after successful runtime registration, preventing failed duplicate starts from changing shared settings.
## Testing
Add coverage for detached-child WebSocket prewarm and between-step tier changes, shared-child override rejection, independent-tier inheritance and reload, and settings updates before registration.
GitOrigin-RevId: f0f3676813a1c59bd77baf95121e2d13e0163a8e
## Why
WebSocket telemetry reparses text frames to extract event kinds that the transport already decodes.
## What changed
Pass decoded event kinds to telemetry and report receive failures separately. Keep JSON parsing for timing metrics and as a fallback when stream event decoding fails. Remove the `tokio-tungstenite` dependency from `codex-otel` and restrict it to tests in `codex-core`.
Limit wrapped error parsing to error events or failed stream decoding, preserving HTTP error forwarding when unrelated stream fields are malformed.
## Testing
Update runtime summary coverage to include receive failures and extend the WebSocket error forwarding test with a malformed stream field.
GitOrigin-RevId: e1f9d200fd6d30ec124a2354bdbc01f3082ddde3
## 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
## Why
Starting a side chat waits for fork and setup requests. Keep the workspace responsive during those requests and let users return to an existing side chat through the sidebar chooser.
## What changed
- Add a clickable `Side chat` tab and `+` chooser, plus the configurable `focus_sidebar_tabs` action bound to `leader t` by default.
- Create workspace side chats in the background, showing loading and failure states with `Enter` to retry and `Esc` to go back. Preserve opening prompts and avoid taking focus when the user has moved away.
- Retain inherited permission profiles and defer startup notifications until the side chat is registered on its owning backend.
- Quiet the parent composer while the chooser has focus and prevent completion popups or repeated activation keys from consuming chooser input.
## Testing
Extend tests and snapshots for loading and failure states, returning to an existing chat, draft preservation, inherited permissions, focus transitions, and deferred MCP startup notifications.
GitOrigin-RevId: 244bcd3f170819e2260f21dc1041cf8899fe048c
## What changed
- Advance the pinned `tokio-tungstenite` and `tungstenite` fork revisions and update the Cargo and Bazel lockfiles.
- Use `OAuthCredentialsStore::File` in the gateway credential test to avoid spending the model discovery deadline on keyring-backed decryption.
GitOrigin-RevId: 2862850215abce478136137b9b68a37f3caaeed4
## What changed
- Expose `RequiredCyberAccessPrograms` so hosts can require an explicit allowed program on a thread. Snapshot the requirement before extension callbacks; hosts must reapply it on cold resume.
- Validate resolved `access_programs` before HTTP and WebSocket model requests, rejecting omitted or disallowed programs. Explicit `Standard` remains distinct from omission. Reject memory summarization and realtime requests when a requirement is present.
- Keep required programs scoped to the parent thread by preventing Guardian reviewers from inheriting its program, including Guardian v2 reviews.
## Testing
Add HTTP and WebSocket coverage for allowed programs, omission, disallowed programs, unsupported providers, and connection reuse. Extend Guardian tests to verify parent-only program scope and that removing the public attachment does not erase the startup snapshot.
GitOrigin-RevId: 9306a9af0e03e7a1728dfeb610cd7ec7517367fd
## What changed
- Configure Bazel to apply `opusic_sys_install_headers.patch` to `opusic-sys` with `-p1`.
- Run the cloud-managed MCP OAuth test with `--no-browser` and keep stdin open until the child exits so EOF cannot race the HTTP callback.
- Serialize the cancelled-refresh test with other auth environment tests and temporarily clear the access-token environment variable.
GitOrigin-RevId: ad76b72ae98320bd0e3ff3231e1ed874332ce38c
## Why
Registry `401` responses during harness key validation previously produced generic relay resets, causing recovery to retry rejected executor credentials instead of surfacing the authentication failure.
## What changed
- Send an authenticated Noise handshake rejection for registry `401` responses without opening an application transport.
- Propagate the rejection as `EnvironmentRegistryAuth` and preserve it in the terminal connection state so recovery stops with a specific authentication error.
- Preserve registry HTTP status codes so `403` responses for stale harness grants and transient service failures can continue through recovery.
## Testing
Add tests that reject tampered authentication rejections and exercise session recovery: `401` stops after one rejected recovery attempt, while `403`, `502`, and `503` retry with fresh harness grants and reconnect successfully.
GitOrigin-RevId: 9a55412e583146c094948618c7c9aeb4fb4b953e
## 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
Add `CloudRequestHandle::submit_user_message` to submit a message with a stable ID using `SubmissionMode::Steer`. Return a `CloudUserMessageReceipt` that distinguishes started, steered, and duplicate admissions while preserving server-provided turn status and duplicate identity.
Report preflight rejections and invalid requests as `-32602`, while preserving uncertain admission outcomes as errors without automatic retries. Keep existing `turn/start` callers on `StartIfIdle` with their existing response and error behavior.
## Testing
Add receipt mapping tests and a mock-server worker test covering submission modes, single admission attempts, uncertain outcomes, input validation, and disconnected reply streams.
GitOrigin-RevId: eba120cf47cf0297b072ea373341ead663fb9bc9
## Why
Legacy `.sandbox-bin` ACLs grant `SYSTEM` Modify access without `WRITE_DAC`, preventing the provisioning service from reapplying the bin policy.
## What changed
- Grant `SYSTEM` inheritable `WRITE_DAC` access when protecting the sandbox bin so it can update permissions on the directory and its children.
- Before legacy provisioning, repair the old ACL through an authenticated owner handle when `SYSTEM` is denied access. Upgrade only the expected SYSTEM entry in a protected, allow-only ACL, reject unexpected permissions, and verify that `SYSTEM` can reopen the directory with `WRITE_DAC`.
## Testing
Extend ACL coverage to check `SYSTEM` permissions on the bin and existing and newly created runner files. Add an ignored Windows integration test requiring LocalSystem and user-owned legacy homes to cover successful repair, repeated repair, and rejection of an explicit SYSTEM deny entry.
GitOrigin-RevId: 2303cdf5182947c2d044c79ac7027a16f0373c7d
## Why
Explicit cyber access program selections were dropped for requests using `CodexAuth::Headers`, preventing the server from evaluating the requested program.
## What changed
Forward explicit program selections for header-authenticated requests, leaving entitlement decisions to the server.
## Testing
Add integration tests covering explicit selections and omission over HTTP and a reused WebSocket connection, preservation of actor and account headers, and propagation of backend HTTP 403 denials without dropping the selected program.
GitOrigin-RevId: 5e549e87a1420ce8a5f1ce5c704cc6b7630af3ba
## What changed
- Open a sidebar chooser when no side chat exists, with keyboard and mouse controls to start a new side chat while preserving the parent draft.
- Animate sidebar opening and closing, including reversing an unfinished transition, when animations are enabled.
- Show context-aware workspace shortcuts in a floating panel after a short delay, and render presets in the same overlay without moving the composer.
- Prevent chooser input from accepting an approval dialog before it has been painted.
## Testing
Add coverage for chooser activation and draft preservation, sidebar animation reversal, shortcut and preset snapshots, and approval input handling.
GitOrigin-RevId: 014112622a94798f4e611756c55112dfd8016051
## What changed
Require the `openai` provider ID as well as `GuardianNativeMultiAgentHistory` to enable native agent history and review of multi-agent calls. Apply the same check to Guardian prompt construction, collaboration tool registration, and Guardian v2 configuration.
## Testing
Add coverage for fresh and resumed sessions with the feature enabled and disabled on OpenAI, and enabled on Bedrock and LiteLLM. Verify that only OpenAI sessions with the feature enabled request native review and include the agent call as evidence.
GitOrigin-RevId: bfbe547b0544e66763dca7d1e1376f805994bcb2
## Why
Versions of `ignore` differ in whether parallel walks report traversal errors at the depth boundary, making the test's expectation depend on the walker implementation.
## What changed
Keep the denied directory within the bounded scan depth in `unreadable_glob_traversal_errors_fail_closed`. Require both bounded and unbounded scans to fail with the denied path and permission error, replacing the CPU-count-dependent assertion.
GitOrigin-RevId: 4ed97253247e0c032648ebc6d4be2a97c3ab261a
## What changed
Extend `guardian_review` to assess recorded MCP tool calls using the current tool catalog, bindings, and approval policy without executing the call or remembering an approval. Return no assessment when policy or a remembered approval skips review, and reject tools blocked by app configuration.
## Testing
Add a scenario test that compares direct and live MCP review inputs, verifies that neither dispatches the tool, and checks that the current app approval policy can skip review.
GitOrigin-RevId: 05746dd0804a0f96d7946468701d5222171ff64f
## Why
Multi-agent V2 still supplied native tool usage guidance when native tools were disabled, leaving instructions for unavailable tools in model requests.
## What changed
Skip bundled and model catalog role guidance for both root agents and subagents when `disable_native_tools` is enabled. Preserve explicitly configured usage hints.
## Testing
Add coverage for omitted bundled and catalog guidance and preserved configured hints with native tools disabled. Update the request snapshot and assert that spawned agents do not receive native tool call guidance.

## Why
Idle reads from local MCP servers on Windows can occupy Tokio's blocking threads and delay unrelated filesystem operations.
## What changed
Use IOCP-backed named pipes for local MCP server stdin, stdout, and stderr on Windows. Connect child endpoints before launch, restrict pipe access to the owner and SYSTEM, and reject remote clients. Preserve the shared legacy and modern protocol framing.
## Testing
Add Windows regression tests to verify that idle MCP reads leave blocking I/O available in both protocol modes and that child output handles support querying the pipe mode.

## What changed
Expose `AgentTurnOutcomeReporter` for hosts to install through `StartThreadOptions::thread_extension_init`. Await its callback after emitting the terminal turn event, independently of native parent notifications, so hosts can handle result delivery and retries.
Track outstanding outcome handoffs and wait for them during graceful shutdown before running thread-stop hooks. Prevent new turns from starting once handoff registration closes.
## Testing
Add integration coverage for completed and errored outcomes, turn lineage, queued follow-up turns, and shutdown waiting for handoffs. Extend Guardian tests to verify that strict safety stops reach the reporter while default interruptions remain silent.

## What changed
- Add Space to set the default provider from Model providers settings, persisting `model_provider` on the connected server. Keep provider details available and disable selection when server configuration or client launch settings fix the provider.
- Apply the choice to `/new` while preserving the current chat. Refresh account details for new chats and reject account data that does not match the started provider.
- Block stale `/model` choices during saves and after confirmed or uncertain provider changes, including across reconnects. Tell users to restart the app server and TUI to refresh the model list, and discard queued picker actions from another backend or chat.
## Testing
Add coverage for provider saves, retry after disconnection, concurrent-save prevention, stale model choices, and account/provider matching, with updated provider-picker snapshots.

Document that `AgentMessageBoard` notification delivery follows the host's
scheduling and wake policy and may buffer notifications for idle recipients.
Link to `MessageBoardHost` for the delivery contract.

## What changed
Replace external `rg` scans and the fallback walker with an in-process `ignore` walker for bubblewrap deny-glob expansion. Remove scanner lookup and dependency tracking from sandbox integrity checks.
Include hidden and ignored files, respect scan depth limits, and fail closed on traversal errors. Anchor patterns to their static search roots and preserve literal leading `#`, leading `!`, trailing spaces, and unclosed character classes. Follow explicit symlink roots while skipping child symlinks, and mask canonical targets of matched paths.
## Testing
Extend unit and sandbox integration coverage for glob syntax, depth limits, traversal failures, symlink handling, commands launched from `/`, and operation without executing `rg`.
