## 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
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.
GitOrigin-RevId: 281a2b7e1faf3a3fc07e007a065b16235eda08b6
## Why
Streaming `bio_policy` failures were classified as generic invalid requests, losing their policy-specific classification.
## What changed
- Add `BioPolicy` errors across the API and core protocol, recognizing streaming failures and HTTP 400 responses, including wrapped WebSocket errors.
- Preserve server messages and use a biological-risk fallback when the message is missing or blank.
- Treat bio policy errors as non-retryable in core and guardian handling, and classify them in diagnostics and telemetry.
- Map `BioPolicy` to `other` in the app-server v2 protocol.
## Testing
Add coverage for error classification, message preservation and fallbacks, HTTP and wrapped WebSocket responses, guardian retry decisions, and app-server conversion. Extend the core integration test to verify that bio policy failures emit a typed error and complete the turn after a single request.
GitOrigin-RevId: 78c2647e8fc8f80297cb8a23fff06ab141099632
## 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 `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
## 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
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
`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
## 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.
GitOrigin-RevId: 56c0767a74143e793aac2ac165d0cbe98a09469b
## 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.
GitOrigin-RevId: af90e1c0d39bab625f2e89786085b61a9b96c0ce
## 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.
GitOrigin-RevId: b3da1becdf86b1869275aacb0ffc2817cee5af2e
## 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.
GitOrigin-RevId: b3ef5805c1c61b8d64b9b896c9c0a79120143667
## Why
The trusted UI host needs the local credential's public metadata to complete backend registration. `userVerification/enroll` previously returned only `credentialId`.
## What changed
- Return `algorithm` and `publicKey` for newly created or reused credentials. The algorithm is `ecdsaP256Sha256X962`; the public key is unpadded base64url SPKI-DER.
- Keep both fields optional in the protocol for compatibility with older app-servers, while current servers populate both.
- Document caller-owned backend registration and revocation, including checking metadata, signing an enrollment challenge with `userVerification/verify`, matching credential IDs, and preserving the authenticated account throughout registration.
## Testing
Add protocol coverage for absent or null metadata and populated-response round trips. Add an RPC assertion for enrollment metadata and extend the local enrollment test to check metadata when creating and reusing a key.
GitOrigin-RevId: f0726e8c430e27559e1a01ba2ea635993cbeba09
## Why
A code-mode cell can outlive its turn. Nested tool calls dispatched during a later turn need the original step's tools and context, while approval handling must still work across that turn boundary.
## What changed
- Retain each cell's originating `StepContext` for nested tool dispatch and cancel queued calls whose context has been released.
- Keep MCP approval metadata available for the lifetime of the running invocation, keyed by server and call ID.
- Apply Guardian denial accounting and interruption to the active turn, including reviews from an earlier cell.
- Carry `turn_id` in legacy MCP begin/end events so history reconstruction and rollout migration assign late completions to their original turn. Preserve the current-turn fallback for older records without it.
## Testing
Add regression coverage for originating tool selection across turns, callback and metadata cleanup, delayed MCP elicitation review, Guardian interruption of the active turn, and late MCP completion attribution with legacy compatibility.
GitOrigin-RevId: 4533379aae6e4ecb4aabe5a25e4aca5d65385d76
## What changed
Add `serverCapabilities` to `mcpServerStatus/list` responses in both `full` and `toolsAndAuthOnly` modes, including thread-scoped reads. Return the initialized server's capabilities object, including its `extensions` map, or `null` when unavailable.
Capture capabilities during initialization so they remain available when tool discovery fails. Clear them on each new connection attempt and keep them independent of shared tool caches. Update the protocol schemas, generated TypeScript and Python types, and documentation.
## Testing
Add coverage for extension capabilities surviving tool-discovery failures in both detail modes. Extend existing tests to check advertised extensions, absent capabilities after initialization failure, and serialization of unavailable capabilities as `null`.
GitOrigin-RevId: 8e9d67c10fac3a54e82bef8be5d99caaf82597d1
## What changed
- Support `model_provider` and `model_providers` in managed requirements. Required selection overrides local and session configuration; each required provider definition replaces the corresponding local entry, including its authentication and headers.
- Merge provider requirement fragments before validation, preserving source-relative `auth.cwd` paths. Reject invalid cloud provider definitions before replacing the cached bundle, including unsupported Bedrock overrides.
- Expose `modelProvider` and `modelProviders` through the configuration requirements API and generated schemas. Reject writes to managed provider settings and omit their local origins, including for provider IDs containing dots.
## Testing
Add tests for requirement precedence, authentication fragment merging, path resolution, cloud cache preservation, and read-only configuration RPCs. Integration tests verify that model discovery and inference use the required gateway and ChatGPT authentication without leaking local headers, and that provider requirements survive configuration rebuilds.
GitOrigin-RevId: d1448604d4ef5662ebb5df7b693712d3b8ad6d54
## Why
Persisted turn-start events lack the originating root turn ID, so they cannot directly associate child turns with the root turn that initiated them.
## What changed
- Add optional `root_turn_id` to `TurnStartedEvent`. Use the inherited root turn ID when available, otherwise the turn's own ID.
- Centralize turn-start emission for regular turns, shell commands, and manual compaction so they record attribution consistently.
- Carry attribution into `ThreadHistoryTurnChange` when processing turn-start events and retain it through completion in the history builder.
- Keep older records compatible by defaulting missing attribution to `None`.
## Testing
Add coverage for root and child turn attribution, persistence when tool collisions fail a turn before sampling, history change propagation, and deserialization of older turn-start records.
GitOrigin-RevId: 54a80b828ca7d1c4c19f13d468c01d052e1b9130
## What changed
- Add `thread/attachment/add`, `thread/attachment/list`, and `thread/attachment/remove` to manage durable resource references without loading the owning thread or changing conversation history.
- Identify attachments by thread, `attachmentType`, and `identityKey`. Repeated adds return the existing attachment; repeated removals succeed without emitting another update. Listing supports cursor pagination.
- Broadcast `thread/attachment/updated` after creation or deletion, after responding to the requester. Serialize attachment mutations with thread lifecycle operations and reject stores that do not support attachments.
- Update protocol schemas, TypeScript and Python bindings, documentation, and TUI notification handling so attachment updates do not add untracked threads to the agent picker.
## Testing
Add coverage for unloaded threads, pagination, idempotent addition and removal, reattachment, invalid inputs, unsupported stores, response-before-notification ordering across clients, and TUI notification routing.
GitOrigin-RevId: 0d29cf903afd4e931a70a9cf96300475213b34aa
## What changed
Add nullable `promptHash` to the upload response, populated from the uploaded `prompt_hash` tag. It identifies the whitespace-normalized SHA-256 of the session base instructions, excludes later developer messages, and is `null` when the reported rollout has no prompt metadata.
Update the protocol schemas, precomputed exports, and generated TypeScript and Python types.
GitOrigin-RevId: 6fa70fbe7a06604ac1cd0ea363eb4f192083dad9
## What changed
Parse optional `generation_id` values from image API responses and carry the selected image's ID through the image generation tool into analytics events. Keep the ID out of serialized extension items, JSON schemas, and TypeScript types. Responses without an ID remain supported.
## Testing
Add coverage for distinct IDs in multi-image responses and responses without IDs. Extend analytics and app-server tests to verify that the selected image's ID reaches analytics, and item tests to verify that it is omitted from serialization and TypeScript types.
GitOrigin-RevId: 70a600856990140b76fdbda51a0d73b3414338b1
## Why
Canceling an elicitation does not stop a separate native verification RPC. Clients need a way to cancel that work and prevent a canceled proof from being delivered while it waits for outbound queue capacity.
## What changed
- Add experimental `userVerification/cancel` with `{requestId}` to signal cancellation of status, enroll, delete, or verify requests on the same connection.
- Return an empty acknowledgment without waiting for native work to exit. Unknown, finished, unrelated, and other-connection requests are no-ops.
- Retain request cancellation state until outbound capacity is available so canceled proofs are checked before enqueueing. Already enqueued responses and completed effects cannot be retracted.
- Document the API, request ID requirements, and independent lifetimes of elicitations and native verification RPCs.
## Testing
Add coverage for experimental opt-in, parameter validation, connection and request ID isolation, cancellation before native dispatch, repeated cancellation, worker-slot retention, and proof cancellation while waiting for outbound capacity.
GitOrigin-RevId: 03fcb83fcc5fab4169c68668822fc0bbb4970938
## Why
Allow v2 memories to build in the background while the selected memory version continues supplying context, and let clients check whether v2 has enough consolidated data and a valid summary to use.
## What changed
- Add `memories.dual_write`, disabled by default, to run v1 and v2 extraction and consolidation concurrently with separate stores and directories.
- Add the experimental `memory/status` endpoint, returning `v2ConsolidatedThreads` and `v2Ready`. Readiness requires a valid v2 summary and a consolidation thread count meeting `minConsolidatedThreads` (default 20, supported range 1–4096).
- Persist the largest thread count from a successful consolidation across pruning and clear it on memory reset.
- Share v2 summary validation between consolidation and status reporting, and tag memory metrics with `memory_version`.
## Testing
Add tests for independent dual-write outputs, preserving existing notes without importing them into v2, and readiness behavior across consolidation ownership checks, missing summaries, configurable thresholds, thread deletion, and memory reset.
GitOrigin-RevId: 54417cc60bf419062401355c0da8c79119995f61
## What changed
- Let approval extensions choose between cached approval, synchronous review, and a user prompt for tool and permission requests, while core enforces mandatory Guardian and fresh-review requirements.
- Carry an optional `review_reason` on Guardian assessment events and use it to trigger strict-review notifications, retaining the fallback for older events.
- Require synchronous review when cached evidence has an unusable encrypted parent compaction.
## Testing
Add regression coverage for manual prompts and cached approvals with non-UTF-8 working directories. Update approval contributors in existing tests to use the decision API.
GitOrigin-RevId: a4e66416070bdaa881daa41429c49021629f44c1
## Why
Device-authenticated verification needs an app response outside automated approval and review. Previously, MCP user-verification requests were always cancelled.
## What changed
- Add typed `openai/userVerification` elicitations carrying a title, description, and challenge through core and app-server.
- Route verification to one connection enabled by trusted host activation. Restrict responses to that owner, exclude requests from replay, and cancel on disconnect or authentication changes, including account switches away and back.
- Return proofs in `content`, discard response metadata, and cancel malformed acceptances. Suppress verification response logging and analytics, and send only a generic verification notice to realtime.
- Keep the mode experimental and exclude it from stable schema exports. Capability advertisement remains disabled, and the TUI cancels verification requests.
## Testing
Add coverage for owner isolation, disconnect and authentication races, proof response handling, automated-review bypass, inactive-host cancellation, stable schema filtering, and realtime payload exclusion. Update the MCP integration test to verify that an activated request holds the tool until the client responds.
GitOrigin-RevId: c8c7b6691a3f7756682bbcca9def1df0d1feb906
## Why
JSON schema exports should be identical across Cargo and Bazel builds.
## What changed
Recursively sort object keys before writing app-server protocol JSON schemas,
while preserving array order.
GitOrigin-RevId: 740c846062f7bae18790e9cf4f30734289ae3056
## What changed
Add `userVerification/status`, `userVerification/enroll`, `userVerification/delete`, and `userVerification/verify` behind the `experimentalApi` capability. Define request, response, proof, and typed error contracts, export their schemas, and document the API.
All four methods currently return `unavailable` with reason `providerUnavailable`; native verification operations are not implemented by this change.
## Testing
Add tests for experimental opt-in, typed provider unavailability, readiness serialization, and rejection of mismatched error reasons and native diagnostic payloads.
GitOrigin-RevId: a858ab41523c5acec7dbf3cfa7fcab693ac44a8c
## Why
Clients need a per-thread Daybreak toggle that survives restarts and can be
restored on resume without changing the access program of an active or future
turn.
## What changed
- Add experimental `daybreakEnabled` support to `thread/metadata/update` and
expose the saved value on thread responses.
- Store the preference in SQLite, including for threads without a first turn,
and preserve it through reads, resumes, reconciliation, and restarts.
- Copy the preference when forking a thread while keeping subsequent updates
independent.
- Keep `daybreakEnabled` separate from the per-turn `cyberAccessProgram` field;
app-server does not derive one from the other.
## Testing
- Cover persistence across restarts, cold reads, reconciliation, and forks.
- Verify metadata updates do not alter the access program of active or later
turns.
GitOrigin-RevId: bcf987a9fcd7b0ac8a88b1c8f0df06b33ed8ad6e
## Why
Guardian approval actions can contain paths from a remote executor whose path convention differs from the host, such as Windows paths reviewed on a POSIX host. Converting those paths to host-native absolute paths prevents the action from being reviewed.
## What changed
- Render command working directories using the executor's reported path convention, and preserve URI-backed paths for attribution.
- Carry foreign command and patch paths through Guardian events and app-server schemas as legacy path strings.
- Bound remote plugin attribution within the overall review deadline and reject Guardian action payloads that exceed the review byte limit.
## Testing
- Cover Windows and POSIX executor path rendering, foreign patch paths, protocol round trips, oversized payload rejection, and remote Guardian review context.
GitOrigin-RevId: 38be0fcdac897139519e74e077eb5cb4f8f8017e
## What changed
- Parse the optional `[browser_use].allow_webmcp` boolean from managed requirements and preserve requirement-layer precedence.
- Return the policy as `browserUse.allowWebmcp` from `configRequirements/read`, including explicit `true`, explicit `false`, and `null` when omitted.
- Update the generated JSON and TypeScript protocol schemas.
## Testing
- Cover parsing, invalid values, layered overrides, and app-server response serialization.
GitOrigin-RevId: a3fd7d1a6f838bb3ab0ac2a644409101a2338ca6
## What changed
- Emit a connection-scoped `deprecationNotice` when `review/start` uses
`delivery: "detached"`, including when validation later rejects the request.
- Preserve detached review behavior while directing callers to use `thread/start`
followed by an inline review for a separate review thread.
- Document the deprecation and migration options in the app-server protocol and
README.
## Testing
- Cover the notice for accepted and rejected detached reviews.
- Verify that omitted, null, and inline delivery do not emit the notice.
GitOrigin-RevId: 4234a09d2bb7ef8053091580175dc8cbe8d7512c
## Why
An empty tool map does not distinguish a successfully returned empty catalog from a server whose startup or tool discovery failed.
## What changed
- Add nullable `toolsError` to each `mcpServerStatus/list` entry when no catalog is available because startup or tool discovery failed.
- Keep `toolsError` null for returned catalogs, including cached and empty catalogs, and continue returning healthy servers when another server fails.
- Update the protocol schemas and generated TypeScript type.
## Testing
- Extend the app-server status integration test with a broken MCP server and verify its error without losing the healthy server's inventory.
GitOrigin-RevId: 30b4ca4d9a45cec6998f5f626d3fddbee90a525d
## What changed
- Add the creation-time `originator` to app-server thread responses and `thread/started` notifications.
- Persist originators in thread metadata and preserve the first recorded value across list, read, resume, rollout, and SQLite paths.
- Add an `originators` allowlist to `thread/list` for hosted backends. The local app-server accepts omitted or empty values but rejects nonempty filters.
## Testing
- Cover originator persistence across server restarts and list, read, and resume requests.
- Verify local `thread/list` handling for nonempty, omitted, null, and empty originator filters.
- Heap-allocate large TUI dispatcher futures in affected tests to keep them within the Windows test-thread stack.
GitOrigin-RevId: 73ad6e61b8fdd2d93a22d1f971723a19ec7be3fc
## What changed
- Add `application.network` managed requirements with exact-domain allow/deny
rules, default-enabled behavior, domain normalization, and normal managed TOML
precedence.
- Return the policy separately from agent network requirements through the
experimental `configRequirements/read` API. The endpoint reports the policy
but does not enforce it.
- Export the new protocol types and schemas, and document the TOML format.
## Testing
- Cover parsing, validation, normalization, layered precedence, and cloud
requirement composition.
- Verify app-server responses, defaults, separation from agent policy, and
rejection of invalid domains.

## What changed
- Add the experimental `Thread.environments` field with each selected environment's ID, working directory, and runtime workspace roots.
- Populate the field from live thread state in start, resume, read, list, and unarchive responses. Use `null` for unloaded threads and an empty list when a loaded thread has no environment selection.
- Document that the field reports selection rather than connection status and does not affect executor selection or resume behavior.
## Testing
- Cover selection updates, unloaded and resumed threads, loaded pathless unarchives, and clients that subscribe after environment connection notifications.

## Why
When ordinary included usage is exhausted, eligible users need a way to keep working with the backend-provided Luna Reserve quota and return to their previous model once ordinary usage recovers.
## What changed
- Automatically switch eligible TUI tasks to Luna Reserve after an authoritative account usage read, preserving the prior model and reasoning effort per task.
- Restrict model selection while on Reserve to its supported reasoning levels, keep queued turns on the accepted model, and restore the saved model after a fresh read confirms recovery.
- Surface Reserve usage in the composer and `/status`, and expose `normalModelSlug` in app-server rate-limit snapshots so clients can use the associated model's display metadata without changing the request model.
- Poll account limits more frequently near exhaustion and retain compatibility with app servers that only accept the legacy null request parameters.
## Testing
- Added coverage for Reserve entry, queued-turn handling, task reconstruction, recovery authorization, account changes, model selection, usage rendering, and banner dismissal.

## What changed
- Accept optional `account/rateLimits/read` capabilities for Luna Reserve support
and lightweight background polling while preserving omitted and `null` params.
- Forward the Luna Reserve capability only for eligible ChatGPT sessions, and let
lightweight polls skip the separate reset-credit detail request.
- Return the backend's `ordinaryUsageAllowed` decision only when its account and
user identity match the active session.
## Testing
- Cover capability defaults, eligible and restricted authentication modes,
lightweight polling, identity filtering, and backend permission handling.

## Why
Permission requests can originate in an environment whose path convention differs from the Codex host. Requiring the request working directory to be host-native prevents those requests from reaching interactive approval.
## What changed
- Carry the request `cwd` as a `LegacyAppPathString` through core events and the app-server protocol so the target environment's native representation is preserved.
- Convert the preserved value back to a `PathUri` when materializing permission grants.
- Regenerate the JSON and TypeScript protocol schemas for the updated `cwd` type.
## Testing
- Exercise the app-server permission request round trip with a target-native working directory across host path conventions.
- Verify remote permission requests retain their environment working directory and granted access still unblocks later execution.

## Why
Compaction replaces the model history window, but host-verified user answers may
still be needed for the rest of the owning thread.
## What changed
- Add bounded, model-invisible retained context for verified
`request_user_input` answers.
- Persist retained context in rollout events and compaction checkpoints, and
restore it when a thread resumes.
- Remove answers when their source turns are rolled back, and prevent
parent-local answers from being inherited by child forks.
## Testing
Add lifecycle coverage for deduplication and size limits, compaction and resume,
rollback, rollout migration, and child forks.

## What changed
- Replace `send_user_message_async` with `request_user_input_async`, accepting one or more questions with optional suggested answers while allowing the turn to continue.
- Attach structured question metadata to asynchronous agent messages while retaining readable fallback text, and preserve it through app-server events, thread history, and generated schemas.
- Continue enabling the new tool for model catalogs that advertise either the old or new tool name.
## Testing
- Cover tool registration, question validation, emitted items, continued turn execution, history preservation, and backwards-compatible deserialization.
GitOrigin-RevId: ffc49aebde2e854c3c50a122aa52805fec3fc6b3
## What changed
- Add nullable `model` and `reasoningEffort` fields to the shared app-server `Thread` object and generated schemas.
- Report current settings for loaded threads and the latest persisted settings for unloaded threads across thread read, list, start, resume, rollback, metadata update, and notification paths.
- Keep unavailable legacy or filesystem-only settings nullable, and allow metadata reads without loading a thread or dispatching queued work.
## Testing
- Cover live-setting precedence, persisted settings after restart, null legacy values, and model metadata returned by thread lifecycle operations.
GitOrigin-RevId: 22ebe8a8d1910a820d90a97730d812a00d8c1372
## What changed
- Add `approvalsReviewer` to the experimental `turn/settings/update` API.
- Apply reviewer changes to subsequently captured steps and new background approval requests while preserving pending approvals and future-thread defaults.
- Allow reviewer-only updates without `step_model_switching`, while continuing to enforce managed reviewer restrictions and model-required auto review.
- Use an explicit live reviewer update for MCP approvals while retaining refreshed thread defaults for clients that have not set one.
## Testing
- Cover switching between user and automatic review during a live turn, future-turn isolation, and managed-authority rejection.

## Why
Guardian review evidence must remain available after a compacted thread is resumed or forked, while rolled-back or parent-local evidence must not grant authorization in a different context.
## What changed
- Store the bounded, model-invisible Guardian transcript alongside compacted rollout history and restore it from the newest surviving checkpoint during replay.
- Trim Guardian history at rollback boundaries, clearing it when the boundary has already been evicted.
- Preserve the checkpoint for user-initiated forks, but remove it when spawning a subagent so parent review evidence is not inherited.
- Keep the new rollout field optional for compatibility with existing compacted records and legacy readers.
## Testing
- Cover Guardian history across compaction, restart, paginated and pathless stores, user forks, rollback, bounded replay, serialization, and subagent forks.
GitOrigin-RevId: 6ab076d5e0c3aac4d6a41ebd50ba2b200c90213e
## What changed
- Add `apps.<app_id>.links.<link_id>` configuration for overriding
`approvals_reviewer` and `default_tools_approval_mode` per connected account.
- Expose link settings through the app-server protocol and generated JSON and
TypeScript schemas.
## Testing
- Extend `config/read` coverage for populated, empty, and absent `links`
sections.
