## What changed
- Remove the private-desktop opt-out from elevated and unelevated Windows sandbox launches.
- Remove `windows.sandbox_private_desktop` and its managed requirement and API fields. Warn users to remove the obsolete setting.
- Require a private desktop name when launching through the Windows sandbox wrapper and command runner.
## Testing
Add coverage for the obsolete-setting migration warning and update wrapper tests to verify a live private desktop is passed and a missing desktop name is rejected.
GitOrigin-RevId: c7135f8d211aac8d812180691c2c1e433d77cde4
## What changed
Add an optional `onboardingSkill` summary to `plugin/read` responses and update the generated schemas, TypeScript types, and Python models.
- Resolve local declarations from `extensions["com.openai"].onboardingSkill`, accepting relative paths with or without `./`. Require the resolved path to stay within the plugin root and match a loaded skill.
- Match remote release metadata's `onboarding_skill_name` against the plugin's skills.
- Return the summary only when the plugin and matching visible skill are enabled; remote plugins must also be available. Otherwise, return `null`.
## Testing
Add parameterized local and remote `plugin/read` tests covering matching, missing, and unmatched declarations, disabled plugins and skills, and unavailable remote plugins.
GitOrigin-RevId: 88cabdfddbecba5efba756617da0cb1ff064bdf7
## Why
Configured filesystem paths can be slow or inaccessible. Doctor needs to identify those paths and their configuration sources without letting a blocked filesystem call delay runtime shutdown.
## What changed
- Add `sandbox.filesystem_paths` to report literal filesystem grants, access modes, resolution outcomes, and configuration sources when available. Exclude deny rules and denied paths without expanding globs or special paths.
- Resolve paths in disposable helper processes, with wait budgets of two seconds per path and eight seconds total, checking at most 32 paths. Warn on slow or unsuccessful probes and incomplete checks; missing paths alone do not trigger warnings. Probes do not test read/write access.
- List paths without probing on Windows or when filesystem read restrictions apply.
- Increase the app-server doctor report timeout from 25 to 35 seconds to accommodate the probes.
## Testing
Add unit and integration coverage for path deduplication and deny filtering, configuration provenance, blocked-helper timeouts, helper execution without loading configuration, and report snapshots for resolved, missing, Windows, and read-restricted paths.
GitOrigin-RevId: b0732265fc2c83ea67acc24b442e39139d705f1b
## Why
MXC's native host-loopback access is bidirectional, so it cannot enforce `allow_local_binding = false`. Treating an omitted setting as `false` prevents managed networking from working with the default configuration.
## What changed
- Preserve an omitted `allow_local_binding` until the executor's sandbox policy is known. Default to `true` for Windows MXC and `false` elsewhere, including remote execution.
- Reject an effective `false` for MXC managed networking after applying policy restrictions, without enabling disabled networking.
- Use the executor's resolved value for remote network approval decisions while preserving explicit controller restrictions.
- Document that local binding permits local servers and direct host-loopback connections and skips additional private-network destination checks; proxy domain rules still apply.
## Testing
Add coverage for per-executor defaults, explicit values, MXC rejection of `false`, and remote network review cleanup with the resolved policy.
GitOrigin-RevId: 0fa7c1eaec68bebada2b8f7af45688315eea70a9
## Why
Resuming a running thread with a summary initial page cloned every active-turn item before discarding those outside the summary, including potentially large reasoning payloads.
## What changed
- Snapshot the active turn using the requested `TurnItemsView`, copying only the first user message and final agent message for summaries and no items for `NotLoaded`.
- Preserve full snapshots when the resume response includes full turns, even if its initial page requests a summary.
- Share item selection between snapshots and page responses, and skip selection when a turn already has the requested view.
## Testing
Add unit coverage for summary selection, completed-turn metadata, and metadata-only snapshots. Extend running-thread resume coverage for default summaries, explicit full pages, and full turns returned alongside a summary page.
GitOrigin-RevId: 6ddcd93c44dbc8083827ac82f442b31730a4edde
## Why
Resuming a running thread cloned the active turn's items even when the response did not need them.
## What changed
Add a metadata-only turn snapshot and use it for resume status checks and initial pages with `TurnItemsView::NotLoaded`. Only snapshot items when including turns or requesting an initial page with items, preserving item data for `Summary` and `Full` views.
## Testing
Add lifecycle coverage for metadata snapshots and extend running-thread resume tests to check metadata-only responses and populated `Summary` and `Full` pages.

## Why
Starting a thread in a directory without a project could persist trust and
preapprove project configuration added later.
## What changed
Track whether configuration discovery found no project-root marker, Git checkout,
or project-local `.codex` directory. Skip implicit project trust in `thread/start`
for these directories. Preserve existing trust decisions and permission checks.
## Testing
Add regression coverage for starting a thread with full access, then adding
project configuration and verifying that a read-only thread does not load it or
persist trust. Add loader tests for projectless classification, project markers,
saved trust, managed configuration, and skipped discovery.
GitOrigin-RevId: da490c649d272494f65d4e22da1ebf89f9085477
## Why
App-server callers that only need the active turn ID or its presence currently create a full turn snapshot, unnecessarily cloning its items.
## What changed
Expose `ThreadState::active_turn_id()` and use it for interrupt validation, elicitation turn ID fallback, and teardown and shutdown logging, preserving the existing turn selection behavior.
## Testing
Update the interrupt integration test to wait for `turn/started` instead of a fixed delay and verify that an incorrect turn ID is rejected before successfully interrupting the active turn.
GitOrigin-RevId: 4a030655fbc4d229809cf13f80c3d7f788f19c13
## Why
`CodexThread` retained the full `SessionConfiguredEvent`, including initial replay messages, and cloned it even for callers that only needed thread or session IDs.
## What changed
Store `ThreadStartupMetadata` without replay history and expose it by reference through `startup_metadata()`. Update callers to read IDs from this metadata. When rejoining a running thread, rebuild the startup response using the supplied resume history for `initial_messages`.
## Testing
Extend the resume test to verify that rejoining reuses the loaded thread, preserves startup metadata, and still returns the original replay messages as a prefix.
GitOrigin-RevId: 9d656063088c28f091d29e5862e4b9d894b7642c
## Why
Model requests need the selected workspace's routing constraints before sending content. A missing cached route cannot establish that a custom ChatGPT-auth destination is independent of the workspace.
## What changed
- Register the account processor as the workspace routing resolver for Responses HTTP, compaction, and WebSockets, enabling origin selection and routing headers while preserving API paths and rejecting routed HTTP redirects.
- Share concurrent discovery by auth generation, workspace, and backend configuration. Recover from discovery-time `401` responses while allowing token refreshes for the same auth owner.
- Require successful discovery before classifying custom destinations as independent, and require a new thread when a workspace-bound session's bootstrap origin changes.
- Refresh managed requirements using retained session configuration without fetching thread configuration again. Return typed routing errors without account or backend details.
## Testing
Extend coverage for discovery-time token refresh, retained provider definitions under managed requirements, and specific invalid-routing error categories.
GitOrigin-RevId: 090cda70daa91ee8acfbc973699d028111e54125
## What changed
- Accept `windows.sandbox = "mxc"` and preserve the selected backend through environment configuration, command execution, patch writes, and sandbox metadata.
- Treat MXC as enabled in the TUI and report Windows sandbox readiness as `ready`, avoiding legacy setup prompts.
- Keep `allowed_sandbox_implementations` scoped to the legacy elevated and unelevated backends without restricting MXC.
- Default `windows.sandbox_private_desktop` to `false` for MXC while retaining `true` for legacy sandboxes.
## Testing
Add coverage for MXC configuration precedence, legacy requirement handling, sandbox selection, and TUI state. Add a Wine integration test that verifies command and patch routing fails when native MXC is unavailable and reports `windows_mxc` in turn metadata.
GitOrigin-RevId: e2162447d0750f60753864c92a20e02a7f297bca
## Why
Older Desktop clients can still provide bundled Sites to an independently updated SSH app-server. A cached remote Sites install must take precedence, even when disabled, while a missing remote bundle must preserve the bundled fallback.
## What changed
- Remove persisted bundled-plugin exclusions, Sites migration checks, and the migration wait when loading local plugin configuration.
- Suppress `sites@openai-bundled` during plugin loading when the remote global catalog is active and a cached remote Sites install is available.
- Remove exclusion-based catalog filtering and read/install guards, and simplify `install_plugin` to accept `ConfigLayerStack`.
## Testing
Expand the agent-turn Sites test to cover enabled remote precedence, disabled remote suppression of bundled Sites, and fallback when the remote bundle is missing.

Use `Box::pin` when awaiting `handle_initialized_client_request` to keep
queued requests small and avoid large stack temporaries during construction.
GitOrigin-RevId: f3d1a6f9129f8b3a612cf054dbbb315ca61601dc
## Why
MCP requests that need human input, including browser sign-in, must be handled by the root thread. Subagents need guidance to hand these blockers to their parent without prompting the user or automatically accepting requests that require input.
## What changed
- Reject interactive MCP elicitations and tool approval prompts in subagents with guidance to ask the parent and wait before retrying.
- Recognize browser authentication and `codex_requires_user_input` metadata even when the form schema is empty, while preserving automatic permission approvals and review decisions.
- Carry user-interaction eligibility through MCP runtime creation and connection reuse, and guard prompt registration.
- Preserve connector authentication diagnostics alongside handoff guidance, subject to normal tool-output limits.
## Testing
Add unit and integration coverage for blocked subagent prompts, root browser authentication, automatic approval and review, connection reuse, and authentication diagnostic preservation and truncation. Add a request-history snapshot for browser-auth handoff guidance.
GitOrigin-RevId: 83e146b6e5c1a2a22a34681ad45615f504b3c96c
## Why
Compression metrics do not distinguish startup runs from runs requested through
`rollout/compress`, making their outcomes indistinguishable by entry point.
## What changed
Pass `RolloutCompressionTrigger` from startup and RPC callers through the
compression worker. Add a `trigger` tag with `startup` or `rpc` to run, file,
scan-error, and temporary-file cleanup metrics, including durations, byte counts,
and compression ratios.
GitOrigin-RevId: f23d9da791b666a7311f2323f6bead6570067798
## Why
Server-level tool exposure settings apply to every connector on the apps server. Individual connectors need a way to opt out of deferred discovery without changing exposure for other apps.
## What changed
Add `apps.<connector_id>.omit_tools_from` with support for `code_mode`, `deferred`, and `direct`. Combine connector omissions with server omissions so app settings preserve server restrictions.
For example, `omit_tools_from = ["deferred"]` makes a connector's tools available without tool search, through direct calls or Code Mode as permitted by the active tool mode and remaining restrictions.
Expose the setting in the app-server protocol, JSON schemas, and generated TypeScript and Python types.
## Testing
Add integration coverage for connector-specific exposure and MCP dispatch across tool modes, server restrictions, and direct-only namespaces. Extend config tests to cover populated, absent, and empty omission lists, and add a Code Mode request-history snapshot.
GitOrigin-RevId: cc99ab290c8a878d06d8d7ccf2d1dbd7c46bfa8a
## What changed
- Add `ResolvedModelMessages` to resolve catalog text and bundled defaults while preserving explicit empty overrides and their source.
- Move base-instruction rendering, Guardian prompt composition, multi-agent role rendering, and `update_plan` guidance filtering into `codex-prompts`; migrate consumers to the shared APIs.
- Separate permission-profile resolution from prompt composition, and annotate Guardian policy and classifier instructions with content kinds.
## Testing
Add and update coverage for missing versus empty templates, literal overrides, multi-agent role composition, Guardian policy substitution and truncation, and preservation of permission path spellings and order.
GitOrigin-RevId: 52335bb7acec0f432d5c57acb2accd5f0276056e
## What changed
Add `rollout/compress` to trigger a best-effort background compression pass for cold local rollouts, even when `features.local_thread_store_compression` is disabled. The method takes no parameters and immediately returns `{}` to acknowledge scheduling, not completion. Existing worker locks, concurrency limits, and cooldowns still apply.
Require the `experimentalApi` capability and reject non-local thread stores. Document the endpoint and the requirement that clients sharing the Codex home support compressed rollout files.
## Testing
Add integration tests for compression with the startup flag disabled, lossless rollout readback, experimental capability enforcement, and rejection of non-local thread stores.
GitOrigin-RevId: be73a3b3f37f3adc54512de8256abf684d5d8112
## Why
Network access and Unix-socket allowlists must not let commands with filesystem restrictions reach the privileged app-server RPC transport.
## What changed
- Bind Unix control sockets in a fixed, user-owned directory with mode `0700`, independent of environment settings, and expose the advertised paths as symlinks. Preserve existing parent permissions, reject unsafe parents, and serialize socket setup and publication.
- Mask the socket directory in Linux bubblewrap sandboxes after each bind that exposes it. Reject host mount aliases and nested mounts that compromise isolation.
- Deny access to the directory and outbound connections to its sockets in macOS Seatbelt policies, including when network access or Unix-socket allowlists grant broader access.
- Require bubblewrap for filesystem-restricted Linux execution. Users with `features.use_legacy_landlock` enabled must disable it for these policies.
## Testing
Add regression coverage for direct and symlink socket access, hardlink attempts, Linux host-process links and bind-mount aliases, and continued use of unrelated and sandbox-local sockets. Add transport coverage for parent permissions, concurrent restart after a stale symlink, and cleanup that preserves a replacement at the advertised path.
GitOrigin-RevId: 53372c27eea278d964f2cf68aed24323ef3b7082
## Why
Permission profile changes reloaded configuration without the thread's session overrides, so profiles defined at thread start could be unavailable to `thread/settings/update`.
## What changed
Reload permission configuration with the thread's merged, enabled `SessionFlags` layers, the effective working directory, and the requested profile. Preserve sandbox executable paths through `ConfigManager`.
## Testing
Add regression coverage for switching away from and back to session-defined and disk-defined profiles, including top-level profile selection. Add a config manager test for merging session layers, excluding disabled layers, and retaining filesystem access to the exec wrapper directory.
GitOrigin-RevId: b0271e28a90cd55d3faf5fdf5f044d768395b0b6
## Why
Executor profile roots can use path conventions that are not native to the current host. Converting them to host paths during configuration or turn reconstruction can reject or drop those roots, while case-insensitive comparison can hide Windows path spelling changes.
## What changed
- Store profile roots as URI-backed `ProfileWorkspaceRoot` values throughout permission snapshots and thread settings, preserving spelling in equality and deduplication.
- Keep effective workspace roots as `PathUri` values for permission materialization and status summaries. Convert Windows sandbox root hints to native paths only at native Windows sandbox boundaries, rejecting incompatible roots.
- Omit the legacy rollout `workspace_roots` field when profile roots cannot be represented as host paths, retaining the compiled permission profile.
## Testing
Add regression coverage for Windows and UNC root spelling changes, settings restoration and turn recording with foreign roots, executor-root status display, and backend-specific Windows root conversion.
GitOrigin-RevId: 903c068fd74959bdd10e7cb1141aa42b953a59a4
## What changed
Keep `shutdown_signal()` pinned across `tokio::select!` iterations and reset it only when it completes, so other events do not cancel and recreate the pending signal listener.
## Testing
Update the WebSocket drain interruption test to use gated responses and keep a second turn active until the `turn/interrupt` reply arrives, preventing shutdown from racing the reply.
GitOrigin-RevId: c939d84ed0e09c2ee49229e81a3becdfa6a4c7f1
## Why
Daemon recovery reloads threads but leaves interrupted work unfinished. Resume eligible work automatically from the saved conversation, even without a connected client.
## What changed
- Attempt one new continuation turn immediately after restoration, including in Plan mode. Mark the old turn interrupted and supply recovery context without creating a user message or granting new authorization.
- Require an idle thread, matching permissions, and the same single local environment configured by the thread. Skip completed, aborted, or superseded work and snapshots without environment identity.
- Add `continue_turn_if_idle` with an atomic previous-turn check so newer tasks or standalone settings changes invalidate pending continuation.
- Preserve the output schema, service tier, and root turn ID, and emit a “Resuming interrupted work” warning when continuation starts.
## Testing
Add daemon restart coverage for continuation without a client, Plan mode, permission and environment mismatches, and legacy snapshots. Add core coverage for preserved continuation metadata, absence of user-message events, rejection of superseded continuations, and exclusion of remote execution from recovery snapshots.
GitOrigin-RevId: 2b290b75d9399fc58258bcda2e85c74e9b5b3b09
## What changed
- Add an optional `WorkspaceRoutingResolver` to `AuthManager` and pass session configuration into routing lookups. Callers without a resolver retain existing routing behavior.
- Apply resolved backend origins and account routing overrides to eligible ChatGPT Responses HTTP requests and WebSocket handshakes. Preserve endpoint paths, validate routing values, and reject HTTP redirects for routed requests, including `NO_CONSTRAINT` routes.
- Key cached WebSocket connections by destination, routing header, and auth revision. Rebuild request setup after credential refreshes and reject account changes during setup or routing discovery.
- Serialize routing lookups per session and retain whether the session has previously been routed.
## Testing
Add tests for path preservation, provider exclusions, concurrent routing lookups, unavailable resolvers, workspace mismatches, redirect rejection, and credential refresh or account changes during request setup.
GitOrigin-RevId: 2b6609019e84a315745c94858955f3f16426fe7f
## What changed
- Accept and ignore `features.personality` in user configuration, profiles, and managed requirements.
- Remove feature gating from `personality = "none"`, which strips the literal `# Personality` section when preparing model catalog instructions. Preserve explicit base instructions and existing thread instructions.
- Document deprecated personality fields in configuration, app-server schemas, and the Python SDK: `friendly` and `pragmatic` no longer select a style, and `supportsPersonality` is always `false`.
## Testing
Add regression coverage for ignored legacy flag values and managed requirements, personality opt-out behavior with the flag absent or set to either value, role overrides, and preservation of explicit base instructions, including empty strings.
GitOrigin-RevId: 4e12c66b42bfc59d6f151a5b3c28fadc6654ae99
## Why
Managed daemon recovery snapshots previously saved only loaded thread IDs, without identifying active turns or preserving their turn-specific options.
## What changed
- Capture regular, uncanceled turns after their input is recorded, saving the turn ID, output schema, service tier, and cyber access program alongside persisted thread IDs.
- Store interruption metadata atomically in the existing candidate array format so older servers can still read thread candidates.
- Begin snapshotting once admitted operations drain, while turns may still be running. Run snapshot collection and thread listener attachment independently of the event loop to keep forced shutdown responsive.
## Testing
Add coverage for running, completed, canceled, and compacting turns; recovery readiness for automatic and user turns; admitted resumes during shutdown; forced shutdown with a blocked rollout writer and child listener attachment; and legacy candidate-array compatibility.
GitOrigin-RevId: ed46342c3a5c71b09c48fa9acece2f15ae748e2f
## Why
Clients need widget presentation details to render MCP Apps without waiting for the full MCP catalog, including when replaying saved history.
## What changed
- Add `mcpToolCall.mcpAppUi` with the invoked descriptor's `resourceUri` and `preferredModelDisplayMode`, and carry it through tool-call events and saved history.
- Support `fullscreen` and default to `inline` when the display preference is missing or unsupported.
- Keep existing resource URI fields for compatibility. Leave `mcpAppUi` null for older history and tools that declare widgets only in result metadata, where clients still use catalog discovery.
- Update protocol schemas, TypeScript and Python types, and app-server documentation.
## Testing
Add parameterized integration coverage for fullscreen, missing and unsupported preferences, legacy URI metadata, and result-only widgets, verifying consistent tool events and preservation across session resume.
GitOrigin-RevId: 2a9bed804dcea8c2b4903b8406fa6710681f7f5e
## What changed
- Accept `fileId` alongside the existing `url` form for app-server image inputs, and forward file references to the Responses API as `file_id`. Update generated schemas and client types.
- Preserve file references, image detail hints, and mixed inline/file image ordering through user-message events, thread history, and rollout migration. Retain file images when truncating tool output.
- Pass file references through image preparation without resolving them, while keeping resize-notice numbering correct. Omit them from unsupported TUI display and Guardian image context.
- Reject image-edit requests whose recent-image window includes a file reference, preventing selection of an older inline image instead.
## Testing
Add coverage for serialization, request and rollout preservation, mixed-image history ordering, incomplete ordering metadata, tool-output truncation, and rejection of unsupported image-edit selections.
GitOrigin-RevId: 6ca20a8577155cc934b720803c3b7b3bffdf972a
## Why
Token plan claims can be stale, and the active account or user can change while a request is in flight. Analytics report selection and account-bound response data need to reflect the verified identity and current server plan.
## What changed
- Fetch the active account's plan once per analytics session and use it to select report endpoints and supported credit breakdowns.
- Add report loading with a fixed end date, account-scoped response caching, and token model filtering. Reuse payloads across grouping changes and evict invalid cached responses so requests can retry.
- Prefer complete attribution for usage breakdowns within the requested range; retain legacy surface/model data when attribution is incomplete and include all features in turn-start breakdowns.
- Add cancellable report-loading state with timeout and interruption errors, and preserve actionable sign-in and retry messages.
- Recheck the active identity after rate-limit reads before exposing account-bound fields.
## Testing
Add regression tests for server plan discovery, report routing and caching, model filtering, attribution fallback, failed-request retries, load cancellation, authentication recovery, and account or user changes during requests.
GitOrigin-RevId: 45c4c09f108c9703893f3ed15613437ebd7c74a8
## What changed
- Track the Windows sandbox implementation separately from its legacy setup level.
- Select dedicated proxy listeners for `WindowsMxc` on Windows across sessions, app-server command execution, and the sandbox CLI.
- Rebuild the session proxy when routing changes, retaining its network policy decider.
- Add a sandbox CLI execution path through the MXC sandbox transform when `WindowsMxc` is selected.
## Testing
Extend configuration assertions for the selected sandbox type and the session refresh test to verify dedicated routing and policy decider retention on Windows.
GitOrigin-RevId: 2a22192636c542022ec81a378a16c1bb6867e145
## Why
`allowedWindowsSandboxImplementations` uses the legacy setup-mode type, which cannot represent `mxc`.
## What changed
- Introduce `WindowsSandboxImplementation` with `elevated`, `unelevated`, and `mxc` variants for configuration requirements, and update the generated schemas and TypeScript and Python types.
- Keep `WindowsSandboxSetupMode` limited to `elevated` and `unelevated`, and update the requirements mapping and its test assertions to use the new type.
- Document that clients selecting `mxc` skip the legacy setup and readiness APIs and use the standard `command/exec` streaming and process-control path.
GitOrigin-RevId: c926e853f0bbdb29d4b437866c284c1394a7ea13
## Why
MXC is a sandbox implementation, not a restricted-token sandbox level. Executor requests need to represent that choice separately from `WindowsSandboxLevel`.
## What changed
- Introduce `WindowsSandboxSelection` for executor sandbox contexts and remove `Mxc` from `WindowsSandboxLevel`.
- Preserve the `windowsSandboxLevel` wire field and its serialized values for compatibility.
- Share sandbox selection between executor process launches and filesystem helpers, and use the new selection in capability discovery and skill reads.
- Disable Windows sandbox selection for executor paths that do not use Windows path conventions.
## Testing
Extend coverage for MXC wire serialization, Windows skill-read sandbox checks, and capability discovery with distinct permissions. Exercise remote filesystem write restrictions with both restricted-token and MXC sandboxes, including rejection when native MXC is unavailable.
GitOrigin-RevId: 266211377bcb138a0dc75861e9ff2225fa37a53d
## What changed
- Capture `CODEX_WINDOWS_REGISTERED_CORE=1` at startup and propagate the selected runtime to sandbox wrappers.
- Launch registered runners through service-recorded execution aliases, validating ownership, OS package identity, and the staged runner image before sending commands. Require service provisioning without falling back to copied helpers or `PATH` lookup.
- Preserve package context for sandboxed child processes and descendants so they can launch executables from the protected package directory.
- Refresh stale package registrations during readiness checks without blocking unrelated RPCs, and reconcile effective proxy settings through the service.
- Resolve setup ownership from the process token and avoid treating the server directory as a writable workspace when setup omits `cwd`.
- Record startup and command outcomes by runtime.
## Testing
Add coverage for runtime selection, package query validation, helper resolution, setup roots, proxy reconciliation, and command result reporting. Add an ignored integration test for environment forwarding, output, and exit status that requires an installed test MSIX and service provisioning in a Windows VM.
GitOrigin-RevId: 976d64039d611be4406c3d0e354820775f8eb6e4
## What changed
Represent images in `ContentItem` and `FunctionCallOutputContentItem` with `ImageReference::Inline`, flattened to preserve the existing `image_url` wire format. Update image producers and consumers and regenerate app-server schemas and SDK artifacts.
Preserve the Python SDK's `InputImageContentItem` and `InputImageFunctionCallOutputContentItem` class names during generation.
## Testing
Add a regression test for stable Python image class names and adapt existing image tests to the shared representation.
GitOrigin-RevId: c38a780ac3314c2ac2deb3afc1b93b94b6f93fec
## What changed
- Add experimental `account/read.workspaceRouting` metadata containing the selected ChatGPT workspace ID, resolved HTTPS backend origin, and routing override (`us`, `us_cr`, or `NO_CONSTRAINT`).
- Discover and cache routing through `accounts/check` for saved logins, new logins, and workspace switches. Return `null` for signed-out accounts, API-only accounts, and saved credentials without a selected workspace.
- Validate discovered origins against required `chatgpt_base_url` origins. Return errors for failed or malformed discovery and retry on later reads.
- Wait for requirements and routing before publishing account updates, including to newly initialized connections. Clear routing on logout, discard stale discovery results, and guard queued notifications against account changes.
## Testing
Add unit and integration coverage for origin resolution and validation, discovery failures and retries, startup discovery, workspace switching, logout, configuration changes during discovery, and authentication changes while notifications wait for queue capacity.
GitOrigin-RevId: 2c5367bb01dd7543b08d374f44444323e40f1981
## Why
Resuming a thread initialized its collaboration mode to Default, losing the saved Plan mode and its developer instructions. Reconnecting clients also lacked a server-reported mode to reconcile changes made by another client.
## What changed
- Restore the saved collaboration mode from the latest matching `ThreadSettingsApplied` event, falling back to the last legacy `TurnContext`. Apply the effective model and reasoning effort while retaining the saved mode and developer instructions.
- Include `collaborationMode` in `thread/resume` responses and update the generated schemas and bindings.
- Use the restored mode in the TUI, including the first prompt after resume. Prefer the server's mode when restoring disconnected input, while preserving the local selection for older servers that omit it.
## Testing
Add regression coverage for persisted and legacy collaboration modes, model and reasoning-effort overrides, the resumed Plan mode display and first prompt, and reconnect behavior with and without a server-reported mode.
GitOrigin-RevId: ed064516e7fae1c1668152ab448f510cbcacfe06
## What changed
Add experimental `thread/start.daybreakEnabled` so clients can set the initial preference for persistent threads. Omitted or null values leave it unset; explicit values are rejected for ephemeral threads.
Return the choice in the start response, `thread/started`, and reads before persistence. Stage it with the initial thread metadata and save it when the thread is persisted. Later changes still use `thread/metadata/update`. The preference does not select `turn/start.cyberAccessProgram` or grant access.
## Testing
Add coverage for true, false, and unset values in responses, notifications, reads, and reads after persistence and restart, plus rejection for ephemeral threads. Update existing metadata and access-program tests to exercise threads with an initial preference.
GitOrigin-RevId: 3bff3dc55a18436067bc2a3f156f5abf52d7321b
## Why
Configuration requirements did not report which login methods the running app server permits after applying managed policy, forced login settings, and workspace restrictions.
## What changed
- Add `allowedLoginMethods` to `configRequirements/read`, using the running authentication manager's effective policy rather than newly read authentication settings.
- Return requirements when login methods are restricted even without managed requirements, while preserving `requirements: null` for the unrestricted default.
- Update protocol schemas and generated TypeScript and Python types. An empty list permits no login method; older servers may omit the field.
## Testing
Add coverage for managed and forced login restrictions, workspace intersections, policy reporting after requirements files change, invalid login methods, and API-only Amazon Bedrock without ChatGPT requests. Extend tests for conflicting authentication requirements and cloud policy precedence.

## What changed
- Remove `AgentSpawner` and `AgentSpawnFuture` from the extension API, along with the Guardian wrapper, thread lifecycle context, and app-server injection plumbing.
- Define `InternalSessionSpawnFuture` directly as a boxed future instead of aliasing `AgentSpawnFuture`.
- Raise the workspace `rustls` minimum version to `0.23.45`.

## What changed
- Extract helper copying, token-user SID queries, provisioning pipe ownership, and service runtime lifecycle into dedicated modules.
- Simplify command-runner resolution and extract setup configuration loading, payload execution, provisioning request exchange, and response handling into helpers.
- Parameterize installation-record registry access and return the saved installation record from authenticated user registration.
## Testing
Add tests for explicit setup `cwd` selection and effective workspace roots, plus valid and invalid token-user SID queries. Move existing helper-copy and freshness tests alongside the extracted copy implementation.

## Why
Command execution and plugin measurement events lack model and reasoning-effort labels. Attribution needs to reflect the step that invoked the command, even when model settings change before a background process finishes.
## What changed
- Add `model_slug` and `reasoning_effort` to command execution and plugin measurement analytics.
- Capture model context from resolved step settings and carry it through execution, approval, Guardian review, and plugin metrics collection.
- Preserve the first command-start model context when subsequent start notifications arrive.
- Keep the carried context out of serialized protocol items and generated schemas.
## Testing
Extend analytics tests to cover model switches before invocation and during background execution, default reasoning effort, Guardian-denied commands, and repeated start notifications retaining the original model context.

Remove entries from the owned snapshot maps when building MCP server status
responses, moving server metadata, tools, resources, and auth statuses into
the response instead of cloning them. Preserve pagination and missing-entry
defaults.

## Why
Desktop uninstall cleanup needs an installation owner even when the user has not signed in or configured the Windows sandbox. Recording ownership only during provisioning leaves those installations unregistered.
## What changed
- Add an authenticated installation registration request and attempt it during Windows desktop stdio initialization, with a five-second timeout before the initialization response.
- Persist ownership independently of provisioning, preserve existing desktop ownership, and prevent another user or home from replacing the registered owner.
- Validate write authority and retain directory handles and guards to protect the registered home against junction conversion through privileged cleanup.
- Preserve existing CLI homes during desktop uninstall while removing their `CodexSandboxUsers` ACL entries. Report ACL revocation errors and avoid propagating unchanged ACLs.
- Grant the owner `WRITE_DAC` on `.sandbox-bin` and allow elevated-helper fallback when older permissions need repair or the service cannot establish an uninstall watcher.
## Testing
Add tests for installation registration without sandbox settings and for preserving a child's null DACL when revoking an absent SID from its parent.

## Why
Direct tool-call records need to stay associated with the invocation that produced each output, including when call IDs are reused. Completeness must describe the recorded call inventory, independently of tool success.
## What changed
- Attach direct-call records to outputs before they enter history, and set `tool_calls_complete` when the invocation's arguments are fully recorded.
- Bound pending recordings and retained metadata, release reservations on completion or cancellation, and invalidate pending records when capture is disabled.
- Apply request budgets to direct metadata and strip it from inference and compaction inputs when capture is disabled.
- Remove executed-call metadata from app-server raw response notifications and exclude its size from Guardian history retention budgets.
- Track call IDs that bypass dispatch so their reuse cannot incorrectly establish Code Mode completeness.
## Testing
Add regression coverage for direct-call attribution, malformed calls, metadata budgets, cancellation, configuration changes, compaction, notification filtering, and Guardian context isolation.

## What changed
- Add explicit MXC backend selection and carry its identity through exec-server process reporting and sandbox violation classification.
- Launch MXC through the Codex executable with the effective permission profile and command environment.
- Reject exec-server MXC requests when native MXC is unavailable or when they request a TTY, an `arg0` override, or managed networking. Reject private desktop isolation during MXC preparation.
- Allow an explicitly empty child environment and avoid exposing request payload values in launcher decode errors.
## Testing
Add coverage for sandbox selection and unsupported-request rejection, plus Windows RPC tests for stdin writes and temporary-directory permissions derived from the command environment. Native MXC tests skip when MXC is unavailable.

## Why
Existing threads retain their model provider configuration, which can stop matching managed requirements after those requirements change.
## What changed
- Check retained providers against current managed `model_provider` and `model_providers` requirements before turn start/steer, review, compaction, manual queue start, and active goal updates. Reject requests when requirements cannot be loaded or no longer match; provider mismatches prompt users to restart Codex.
- Load managed requirements independently of user, project, system defaults, and thread configuration, and resolve Bedrock provider overrides before comparison.
- Keep interrupt, realtime stop, and goal pause/clear available. Realtime connections use separate routing and are outside these checks.
- Make detached reviews inherit their parent thread's configuration.
## Testing
Add unit and integration coverage for provider selection and definition changes, Bedrock overrides, requirement load failures, unchanged queue and goal state after rejection, and continued operation after local configuration changes. Extend detached review coverage to verify inheritance of the parent's provider route.

## What changed
Remove `thread/rollback`, its request and response types, generated bindings, and the core `Op::ThreadRollback` operation. Requests now follow the generic unknown-method rejection path. Document `thread/revert` as the alternative for paginated threads.
Keep historical `ThreadRolledBack` markers and legacy error deserialization so existing rollouts remain compatible with replay and migration.
## Testing
Adapt retained-context and Guardian history tests to append legacy rollback markers and resume threads, preserving coverage of surviving instructions, answers, and review history.

## What changed
- Accept `disabledPluginIds` in `thread/settings/update` and `turn/start`. A supplied list replaces the saved selection; omission or `null` preserves it, and `[]` clears it.
- Return the selection in thread start, resume, and fork responses and `thread/settings/updated` notifications. Update generated schemas and client types.
- Restore disabled plugin IDs from the history retained at the requested fork boundary, preserving explicit overrides.
The selection persists across resume but does not yet filter plugin capabilities.
## Testing
Add coverage for replacing, preserving, and clearing selections without inference; turn-start notifications; resume; and fork boundaries across legacy and paginated history, with loaded and restarted parents. Add a core regression test for history restoration and explicit clearing.
GitOrigin-RevId: 654a8c2a0527228d422c0dd4919228447e2663db
## What changed
Carry optional `available_access_programs` metadata through model information, presets, caches, and the TUI, and expose it as `availableAccessPrograms` in app-server `model/list` responses. Update the generated JSON schemas, TypeScript types, and Python models.
Preserve the distinction between missing metadata and an empty `cyber` list. Ignore unknown cyber program names when reading the catalog so new server programs do not prevent older clients from loading it. Discovery metadata does not grant access; inference still enforces authorization.
## Testing
Add coverage for absent, null, empty, and populated metadata, unknown program names, and app-server serialization. Extend cache tests and verify that online refreshes persist changed access metadata even when the catalog ETag stays unchanged.
