## What changed
- Capture history, prompt metadata, routing state, authentication ownership, and context-window identity for background compaction requests.
- Send background requests over HTTP while preserving foreground routing, and retain the latest candidate in session memory.
- Add feature and threshold eligibility checks and deduplicate attempts by history version, model, compaction hash, and authentication ownership.
- Cancel and drain background tasks during session shutdown, preserving completed usage accounting.
The background launch helper is not yet connected to the turn loop.
GitOrigin-RevId: 0e5e6ab7dac4d98a836733668a775ac48b5a59f1
## What changed
- Extract an HTTP Responses executor that can run without owning a turn's WebSocket state, with optional authentication-owner checks.
- Add cancellation-aware compaction output collection that records background token usage against the rollout budget.
- Support installing a compacted history prefix while preserving later history items and placing initial context around real user or agent messages.
- Allow callers to supply a context window for history trimming and a captured window for compaction request metadata.
GitOrigin-RevId: 29f3ca0ae8841f295058feb207e3a225af9a1487
## What changed
Register the disabled-by-default `async_compaction` feature and accept either a boolean or a `[features.async_compaction]` table. Add `model_async_compact_threshold_percent` with a default of 65 and a valid range of 1–100, validated even when the feature is disabled. Setting a threshold alone does not enable the feature.
Expose the threshold in the runtime configuration and update the JSON schema for both configuration forms.
## Testing
Add configuration loader tests covering boolean and table forms, default and custom thresholds, explicit enablement, and rejection of out-of-range values.
GitOrigin-RevId: cf33de76878e7044bc8cf5d146375a07ea9eb078
## Why
Inputs arriving during turn finalization could be queued after the final batch had already been drained, or recorded ahead of that batch.
## What changed
Mark active turns as finishing before draining pending input. Reject injection into finishing turns and make late client responses and notifications wait until the final batch is recorded before appending to history. Continue accepting input into turns reserved but not yet started.
## Testing
Extend the task-completion test to block final recording, verify that input admission is closed, and confirm that a late notification is recorded after queued input while preserving the notification truncation budget. Strengthen the retained-tool-output scenario to assert tool output names and ordering.
GitOrigin-RevId: a57e44bd974e60e134183dab989795e2c3538596
## Why
Incomplete responses such as `max_output_tokens` were classified as stream errors, allowing retries and compaction model fallback after the response had hit its output limit.
## What changed
Introduce `ResponseIncomplete` errors that preserve the server-provided reason and stop stream processing immediately. Make these errors non-retryable and stop compaction without falling back to the selected model. Record incomplete responses separately in sampler failure metrics.
## Testing
Add regression tests that verify incomplete responses surface a terminal error without retries over SSE and WebSocket, and that compaction stops without retrying or switching models for both local and remote compaction.
GitOrigin-RevId: 6e107d441b9bf03fa47ea47b88eeb94b71a9f729
## Why
Restoring unnamed thread permissions after configuration loading leaves network proxy initialization and permission validation using the configured default. A saved read-only thread should also resume when that default is incompatible with current managed requirements.
## What changed
Apply eligible saved permission profiles during configuration loading, before network preparation and final validation. Keep explicit permission overrides and managed requirements authoritative, preserve managed deny-read restrictions, and reject saved external enforcement or materialized filesystem grants. Include the saved profile in the app-server's prepared resume configuration state.
## Testing
Add regression coverage for resuming saved read-only permissions with an incompatible full-access default and for retaining managed, remembered, and newly approved network domains in the restored profile's proxy allowlist.
GitOrigin-RevId: 73e32b0a31ac678fd3f60a8ccf8fa9df627f16c3
## Why
Windows and WSL can share `CODEX_HOME` without sharing a lock namespace, allowing cleanup to remove another platform's live helpers. Older clients can also clean helpers stored under the shared `tmp/arg0` root.
## What changed
Create helpers under `CODEX_HOME/tmp/arg0-<os>` and limit stale-directory cleanup to that operating system's root. Keep permission discovery compatible with both the current platform's root and legacy `tmp/arg0` directories, while ignoring other platforms' aliases.
## Testing
Add regression coverage for cleanup isolation, live helper preservation during legacy cleanup, and selection of the first session alias directory from either supported root.
GitOrigin-RevId: f34292748b5b1d3c25629604d849db4b133dfa3a
## Why
Local message boards were scoped to an agent tree. Independently created Codex runtimes need a way to share a board while receiving different access permissions.
## What changed
- Add `LocalBoard` and `LocalBoardConnection` so hosts can supply read-only or read-write access through `thread_extension_init`, including for isolated, ephemeral runtimes.
- Allow read-only connections to read and manage their own subscriptions; reject posting, replying, channel creation, and changes to another agent's subscriptions. Expose effective permissions in channel discovery.
- Use unique runtime paths and require matching board IDs and canonical database paths when resolving agents or delivering notifications.
- Document explicit extension installation and connection setup for new runtimes, cold resumes, and forks.
## Testing
Add a scenario and context snapshot covering an independent writer and isolated Guardian sharing a board through a symlink alias, read-only permission denials, subscription and explicit notifications, and rejection of notifications to an unconnected runtime before a post is written.
GitOrigin-RevId: f92410c3a5c6a46920c3e0e71849c85dc83d9c31
## Why
With `multi_agent_v2.disable_direct_message` enabled, an unavailable agent message board could cause tool router construction to reject the turn.
## What changed
Remove the requirement that the router expose the board's `post` tool. Unavailable board calls return an unsupported-call error to the model, allowing the turn to continue.
## Testing
Update scenario coverage for a disabled board feature, legacy agents, and ephemeral sessions. Assert that unavailable board calls return an error to the model, that `post`, `send_message`, and `followup_task` are not advertised, and that no board database is created.
GitOrigin-RevId: cb9571459c128d84c3c96f185e70c404e0463473
## What changed
Add a unified execution test where `exec_command` yields a session and a subsequent `write_stdin` poll completes after the remote process exits while its output stream remains open. Verify that the poll returns the delayed output and exit code, emits the command completion event, and removes the background session without issuing a `process/read` request.
GitOrigin-RevId: 3a316eb9f6b29682da81a2ecbdda52f659f4b792
## Why
A remote process can exit while its output stream remains open, leaving the exit watcher waiting and delaying `ExecCommandEnd` even after output collection finishes.
## What changed
Cancel the process output token after final collection or polling, on one-shot cancellation, and after confirmed termination. This releases the exit watcher while allowing delayed output to be collected before the final poll completes.
## Testing
Add remote process event tests for output streams that remain open at the collection deadline, during interruption, and during explicit termination. Assert that `ExecCommandEnd` preserves the exit code and aggregated output, background terminals are cleared, and interruption and termination require no extra `process/read` requests.
GitOrigin-RevId: 8346e5ce446280915b6e2ffa362fcfd79280bfff
## Why
Cold resume can replace saved unnamed permissions with current configuration defaults or recover an executor's permissions from turn context. A first-turn context can also predate an acknowledged settings update.
## What changed
- Restore eligible unnamed permission profiles from settings snapshots owned by the resumed thread, honoring explicit caller overrides and current managed requirements.
- Use owned snapshots as the authority for named permission profiles and reapply workspace permissions for the resumed workspace roots.
- Persist a thread-owned settings checkpoint after the first turn's context, serialized with settings updates so older checkpoints cannot supersede newer settings.
## Testing
Extend regression coverage for cold resume with changed defaults, managed permission restrictions, workspace-root overrides, foreign snapshots, and settings updates during first-turn processing.
GitOrigin-RevId: e411d9fd3d586a4162498c9c77c4184459071bd1
## What changed
- Group preferences into Appearance, Notifications, Input, Sessions, and Text selection tabs, with search and links to existing theme, status line, terminal title, and keyboard editors.
- Persist preference changes to the selected local configuration file, apply supported changes immediately, and show save errors, configuration overrides, and restart requirements in the panel.
- Add a delayed notification test and controls for notification timing while preserving custom event filters.
- Add `tui.copy_on_select_clear_selection`, disabled by default, to clear transcript selection highlights only after confirmed automatic clipboard delivery.
- Keep local configuration editors usable while disconnected and prevent held activation keys or buffered input from triggering actions across editor and reconnect transitions.
## Testing
Add regression tests and rendering snapshots for panel navigation, search, dependency states, editor handoffs, offline persistence, notification timers, custom filter preservation, and confirmed-copy deselection.
GitOrigin-RevId: a16d218046060fcb6e61705a803fcd9297266e6e
Extend `hung_grpc_stdio_host_is_reaped_and_the_session_recovers` to assert that the first execution after host replacement reports lost stored values and running cells. Verify that this rejected execution does not store a value and that the next execution succeeds.
GitOrigin-RevId: 2fc5550c32774321a969b56ba59153de0e497f19
## Why
Client-supplied tool outputs can carry task instructions. Even when marked with `retain: true`, these instructions could be trimmed before compaction and disappear from the compacted history.
## What changed
Add the disabled-by-default `retain_client_tool_outputs` feature to honor retention for explicitly marked, named `function_call_output` items without a `call_id`.
- Preserve eligible outputs in remote compaction v2 and when starting a new context window, keeping their original role.
- Stop emergency tool-output trimming at a retained output.
- Share the existing 64,000-token retention budget, keeping outputs whole and dropping an oversized output and older items rather than partially truncating it.
- Place initial context before retained standalone outputs and account for their images in retained-image counts.
## Testing
Add a scenario covering enabled and disabled retention, emergency trimming, oversized-output handling, and preservation of the latest instruction after compaction and cold resume. Verify that retention annotations stay out of model requests.
GitOrigin-RevId: 449179670e4d2be2623928700738758e43b5dc1a
## What changed
- Add the disabled-by-default `output_token_replay` feature to request `output.encrypted_content` from OpenAI providers.
- Preserve encrypted message and tool-call output, message and function-call status, and output-text `annotations` and `logprobs` through history and replay. Update the generated protocol schemas and SDK types.
- Strip output ciphertext from requests to other providers while retaining it in stored history, including after replay is disabled. Remove encrypted content from memory extraction inputs.
## Testing
Add integration coverage for the feature/provider combinations, metadata replay across follow-up requests, and history preservation when resuming with replay disabled.
GitOrigin-RevId: 77729a021b6771933402aebe74ece8eb39c057e2
## What changed
Add `model_messages.tools.incremental_tools` overrides for the update hint, tool and namespace removal headers, and namespace instruction update and clearing messages. Missing, null, or over-512-byte values fall back to bundled wording; empty strings omit static text while retaining runtime names and instructions.
Substitute `{name}` in namespace message templates and append runtime instructions verbatim. Wording changes alone do not trigger tool catalog updates.
## Testing
Extend unit tests and MCP request-history snapshots to cover custom wording, empty notices, tool removal and restoration, and namespace instruction changes and clearing without repeating unchanged tools or notices.
GitOrigin-RevId: 22dea0a6fb4cfcd646f5e65346424834c8b7d5a2
## What changed
- Add `grpc+stdio://` as a host transport and the disabled-by-default `code_mode_host_grpc` feature flag to select it.
- Share a lazy HTTP/2 channel and host process across code-mode sessions while keeping session state isolated.
- Use HTTP/2 keepalives to detect unresponsive hosts, kill and reap disconnected children, and spawn a fresh host on reconnect. Exit the host when its stdio connection closes.
## Testing
Add coverage for shared-host session isolation, host exit on stdin EOF, and recovery after an unresponsive host is reaped. Exercise nested tool calls with both legacy stdio and gRPC stdio, asserting that the feature flag selects the expected transport.
GitOrigin-RevId: 31389d8540de236b8e0571d3c24e29e117b75c4a
## What changed
Pass the parent turn's `cyber_access_program` to Guardian reviewers and asynchronous classifiers. Use `daybreak_blue` for either Daybreak selection, preserve `standard`, and omit `access_programs` when no program is selected.
Capture the selection with the owning turn so asynchronous observations retain it across later turns. Resolve classifier programs using current authentication and the same provider and API-key feature policy as ordinary model requests.
## Testing
Add regression tests for program changes across reused reviewer sessions with API-key and ChatGPT authentication, snapshot and conversation classifiers at low and high risk, and enabled, disabled, and unsupported-provider API-key policies. Verify parent requests retain their selected program.
GitOrigin-RevId: 447f306df3a6bd6805464b819950690c751b04b4
## Why
JavaScript objects containing Serde's reserved JSON keys can be reinterpreted during deserialization, allowing nested `RawValue` markers to bypass the parser's normal recursion limit.
## What changed
Reject `$serde_json::private::RawValue` and `$serde_json::private::Number` object keys before passing V8's serialized JSON to `serde_json`. Report a `reserved JSON object key` serialization error while continuing to allow marker text in strings and longer keys.
## Testing
Add runtime regression coverage for nested and escaped marker keys, recursion limits, normal JSON conversion, and session recovery without overwriting stored values. Extend the host-backed integration test to verify that stored values remain available across turns after rejection.
GitOrigin-RevId: 27ddce08e1ffe98ec9dffe02473a815ceae2cc89
## Why
Resumed threads can retain stale capability root locations when the current environment supplies an explicit owner configuration. Matching roots from that configuration previously could not refresh persisted thread roots.
## What changed
Refresh persisted roots from the current attachment when both the root ID and environment ID match, including roots selected by owner-provided configuration. Preserve persisted locations when no matching root is supplied, and continue using the owner's selected roots rather than the executor's shared roots.
Apply the same merge behavior to capability root inspection and per-step resolution.
## Testing
Extend the remote environment regression test to cover owner-provided configurations with and without refreshed roots, including an executor root location that differs from the owner's selection.
GitOrigin-RevId: ad3a639924b348d6d5337ccc64dc8c08234276e3
## What changed
Move `ExecServerProcess` into `core_test_support::exec_server` and update the sandbox, plugin, access, and turn-input tests to use it. Preserve the fixture's startup timeout, temporary `CODEX_HOME`, WebSocket URL discovery, and child-process cleanup.
GitOrigin-RevId: 152de3a83f4ad39e2c1223e15438608dba452850
## What changed
Add `TurnInput::AnnotatedResponseItem` with a caller-supplied `retain` annotation. For function-call outputs, `retain: true` sets `client_authored` history metadata while keeping annotations out of model requests. Accept annotated items through the existing turn submission paths, including continuation.
## Testing
Add an integration test covering retention metadata during turn start, steering, idle submission, and rollout storage. Verify that ordinary outputs remain unmarked and model requests contain neither `retain` nor `client_authored`.
GitOrigin-RevId: 7285dde31149b17b0dcf31d4ea1c7cba66d9efe6
## Why
A credential bound to a host with MITM hooks could also be used at an alias without hooks, allowing the proxy to inject the real credential without enforcing hook policy.
## What changed
Reject requests to unhooked aliases when their selected brokered credentials are also bound to a hooked host. Check both HTTP forwarding and MITM requests before replacing dummy credentials, returning `403` with `blocked-by-mitm-hook` for denied requests.
Use the same destination and credential-selection rules for alias checks and injection, including configured URL prefixes, safe paths, equivalent credentials, merged Basic authentication fields, and environment scope.
## Testing
Add regression coverage for built-in and configured provider aliases, IPv6 destinations, credential selection, and unrelated credentials. Add an agent-started proxy test that verifies credential masking and alias denial.
GitOrigin-RevId: 12be41654761cedcf87b170f7661d6566f7a864e
## Why
A tool can return before its background watcher emits `ExecCommandEnd`. Waiting for that event first can discard an earlier `TurnComplete`, causing the shell snapshot test helper to time out.
## What changed
Update `run_tool_turn_on_harness` to track both the matching `ExecCommandEnd` and `TurnComplete` in a single event loop, returning only after both have arrived regardless of order.
GitOrigin-RevId: c9b749a46eda1244aa3e80fd88b663d110d67d1b
## What changed
Add the disabled-by-default `subagent_default_context_limits` feature and expose it in the configuration schema. When enabled, shared configuration for spawning and resuming subagents clears inherited `model_context_window` and `model_auto_compact_token_limit` overrides so subagents use their model's default context window and auto-compaction threshold.
GitOrigin-RevId: 5168ae2b4fbe72c533d8c6152922a8bceb2c5cbd
## Why
A local command can exit while a descendant keeps its inherited output pipes open, delaying `exec_command` completion and turn completion.
## What changed
Start the bounded output drain when a local exec-server process exits, whether exit is reported by an event or recovered through `process/read`. Remote execution continues waiting for output closure so buffered or delayed output is retained.
## Testing
Add regression coverage for local shell snapshot execution completing before a descendant releases stdout, preserving the foreground output and exit code. Add remote event-stream cases that retain output arriving after both reported and recovered process exit.
GitOrigin-RevId: d38bcd394be42cf48d2af02733e883b02d1dd62f
## Why
The remote environment test can steer before the wait tool call is recorded, discarding the call. The session replacement test can close the client while agents overview RPCs are still pending, leaving the proxy writing to a closed socket.
## What changed
- Wait for the `wait-for-active-environment` function call event before steering the active turn.
- Wait for `AgentsOverviewThreadsLoaded` before shutting down session replacement test cases that open the agents overview.
GitOrigin-RevId: 886112a56ff6e1016efe30dbbd0256807bc1cc85
## Why
Remote boards can allow replies while denying new threads. Agents need to discover these effective permissions and receive actionable details when an operation is denied.
## What changed
- Expose optional `board_permissions` and per-channel `permissions` in `get_channels`, preserving the legacy response shape when permission metadata is absent.
- Preserve HTTP 403 `permission_denied` responses as structured tool errors with a message and optional `action` and `resource`. Mark denied calls as unsuccessful and truncate oversized error details to fit the output budget.
- Pass through service-computed permissions without evaluating access rules locally.
## Testing
Add remote-board scenarios for direct tools and code mode covering legacy responses, reply-only permissions, a denied post, and a successful reply, plus a snapshot of the direct tool exchange.
GitOrigin-RevId: 76594bbc0a1283ff3c3c8682bd7615baa5ade428
## What changed
Add `preserve_fork_prefix` to the multi-agent v2 configuration, defaulting to `false`. When enabled, full forks retain the parent's model-visible history, including commentary and tool records, and append the child's instructions. Legacy compaction without a reusable context baseline still rebuilds the child context.
Mark copied history as inherited, complete unfinished tool calls in the fork snapshot, and exclude inherited manual approvals from authorization review while retaining them in model context.
## Testing
Add coverage for preserved request prefixes, child instructions, legacy and paginated histories, Code Mode, missing inherited tool outputs, compaction fallback, and approval isolation across checkpoint replay. Update the noisy helper failure test to read its response before starting cleanup.
GitOrigin-RevId: ce9235dfa111c88d6ce66cb93d564fb63b326489
## Why
Realtime v3 voice validation used the v1 voice list, limiting the available voice choices.
## What changed
- Add a dedicated `v3` voice list containing the v1 voices and 16 additional voices, and use it to validate v3 requests.
- Expose `v3` in `RealtimeVoicesList`, defaulting to an empty list when omitted during deserialization.
- Update the configuration and app-server schemas, generated TypeScript and Python types, and voice-list test expectations.
GitOrigin-RevId: 7fc8060fe01d840f28eb92c3dfe49c5878c3c258
## What changed
- Remove `ContentItemMetadata`, provenance and namespace types, and the `content_item_metadata` protocol field while retaining `content_item_kinds` classifications.
- Simplify context fragments, extension contributions, and hook output to carry content without source attribution. Return MCP tool results directly without an attribution wrapper.
- Render context-window hints together in a single text fragment.
## Testing
Update Responses and Responses Lite request assertions to expect content-kind classifications without per-content attribution, and adapt context, hook, and extension tests to the simplified types.
GitOrigin-RevId: 201894cd4c93c6d4b4c41c845e7a9af1dd3c95ca
## What changed
Add `history_initialization` to `x-codex-turn-metadata`, distinguishing `new`, `cleared`, `cold_resume`, `warm_fork`, `cold_fork`, and `supplied_history`.
Classify forks by whether the source runtime is loaded and has not shut down. Preserve the classification for the runtime's lifetime, including warm resumes and compaction. This records how history was initialized; it does not establish whether tool metadata is missing. Reserve the field against client-supplied overrides.
## Testing
Extend coverage for warm and cold forks, cold resumes, warm reconnects, supplied history, WebSocket metadata serialization, and reserved-field filtering.
GitOrigin-RevId: 468153512a84d0f4d4ea742198a29e0fa3873a72
## What changed
- Add the disabled-by-default `features.credential_masking` flag to enable credential brokerage through an already enabled network proxy, retaining custom credential providers and managed configuration precedence.
- Prevent project configuration from overriding credential masking and apply existing credential-broker protections to project shell settings when masking is enabled.
- Keep brokerage inactive when the proxy is disabled. Warn at startup and after permission-profile changes when masking is inactive because sandboxing or the proxy is disabled, or provider environment keys conflict.
## Testing
Add coverage for configuration precedence, project protections in both configuration loaders, permission-profile transitions, inactive-masking warnings, and shell snapshot masking of built-in and custom credentials.
GitOrigin-RevId: 4bcb293356e8c1524bdaa4f1b95cbc1e935a5271
## What changed
Move incremental tool guidance out of namespace descriptions and into a developer message preceding each namespace declaration batch after the initial catalog. The notice covers newly added namespaces as well as changed ones, explaining that earlier tools remain available unless explicitly removed and that newer definitions replace earlier ones.
Retain the notice alongside tool declarations in full-history agent forks, and discard it when legacy compaction forks rebuild those declarations.
## Testing
Add unit coverage for multiple new namespaces sharing one notice. Update request-history snapshots for tool changes, removals and restoration, and regular Responses requests. Extend resume and fork tests to cover notice preservation without duplication and removal when rebuilding declarations.
GitOrigin-RevId: 05f79f5eb378a355cf935eabf63951015a9b454b
## Why
Disabling OpenAI analytics also disabled explicitly configured OTLP metrics collectors. Users should be able to export metrics to their own collectors independently of `analytics.enabled`.
## What changed
Apply the analytics preference only to the built-in `statsig` metrics exporter. Keep custom OTLP HTTP and gRPC exporters enabled regardless of that preference, and use `otel.metrics_exporter = "none"` to disable metrics export. Clarify these settings in config documentation and the schema.
## Testing
Cover exporter selection across explicit and default analytics preferences. Update app-server and daemon telemetry tests to verify custom metrics export with analytics disabled, and worktree tests to disable metrics through the exporter setting.
GitOrigin-RevId: 0c61f0f01e2b694db642ac7e7fd1dac9965c7d96
## What changed
- Add `tui.keymap.global.leader`, defaulting to `ctrl-x`, and symbolic bindings such as `leader c` that follow the configured prefix. The default prefix yields to existing custom shortcuts and chord prefixes.
- Keep leader shortcut hints open until completion or cancellation, while ordinary chords retain their one-second timeout. Pressing `esc` or repeating the leader cancels the pending shortcut.
- Add leader configuration and a `Use leader...` capture option to `/keymap`, with resolved shortcut labels and conflict validation.
- Cancel pending chords when input targets change, on paste or focus loss, and on mouse actions other than movement.
- Move the default voice mute shortcut from `ctrl-x` to `f9` and update its tests and displayed hints.
GitOrigin-RevId: 35b964cccd2812c73200f0c26b0f19506821df92
## What changed
Allow mouse selection and plain-text copying of rendered status and footer text, honoring `tui.copy_on_select` and existing selection keyboard controls. Keep the selected region stable while other content updates, preserve Unicode and terminal hyperlinks, and clear selections when their region becomes invalid.
Defer warning clicks until a stationary mouse release so dragging selects text without opening the warning viewer. Preserve the composer draft and cursor while selecting footer text.
## Testing
Add unit and snapshot coverage for visible-text copying, Unicode and hyperlinks, selection invalidation, keyboard ownership, and stationary clicks versus drags. Add a fullscreen integration test for warning selection and draft preservation.
GitOrigin-RevId: dd14d7ede52e97e507be24c4d6ac0299f7388a9b
## Why
Fixed argument limits truncated recorded tool calls even when their metadata fit within the available message budget.
## What changed
- Remove the 8 KiB per-call and 32 KiB per-output argument limits for direct calls and Code Mode.
- Preserve full recorded arguments while retaining message metadata budgets, pending-call limits, and the direct metadata retention limit.
- Rename the normalization helper to `normalize_executed_tool_call_completeness`; it now only clears completeness when calls or tool names were lost.
## Testing
Update regression coverage for large arguments, escaped inputs, reserved-key wrappers, and argument and result metadata preservation across Code Mode waits.
GitOrigin-RevId: 8c199ccf39191d5d44eef02d28b1773654735b43
## What changed
Add the disabled-by-default `guardian_trust_orchestrator_connectors` feature flag. When enabled, Guardian V2 accepts connectors with nonblank IDs from the host-owned plugin service orchestrator as a trusted source without requiring a matching user configuration declaration.
Distinguish orchestrator provenance from user configuration in trusted-tool context. Trust remains scoped to the exact server or connector identity and source; descriptions, outputs, other tools, and other connectors remain untrusted.
## Testing
Add coverage for host-owned connector context, rejection of extension-owned Apps lookalikes and blank connector IDs, source-specific trust metadata, and context token limits. Snapshot the connector approval request history.
GitOrigin-RevId: fbd87dd71110ca7b2b92d50eef02e1e739a74a02
## Why
Tools that do not opt into parallel execution acquire an exclusive scheduler lock, serializing independent reads.
## What changed
Allow skill listing and reading, memory listing, reading and searching, conversation history search and reading, plugin listing, agent listing, current time, remaining context, and `get_goal` to run in parallel. Keep goal creation and updates serialized.
## Testing
Add `cloud_skill_reads_run_in_parallel`, which uses a barrier to require two cloud skill reads to overlap and verifies that each returns the expected resource contents.
GitOrigin-RevId: 97b5634f1f84be2ba092be89e6e9c634ca75c07b
## Why
Subagents should retain the spawning turn's selected skills and plugin choices whether `fork_turns` is `none` or `all`. Capability selection should not depend on copied conversation metadata.
## What changed
- Use a shared child startup path for fresh and history-forked agents, inheriting selected capability roots from the spawning environment snapshot.
- Pass the spawning turn's `disabled_plugin_ids` through both spawn handlers. When omitted, inherit the parent's current choices; explicit lists, including an empty list, override them.
- Resolve the parent before startup so inherited client MCP settings apply even when only the session source identifies the parent.
- Carry plugin choices into delegates with inherited isolation and preserve saved capability roots when resuming a child.
## Testing
Add regression coverage for executor skill listing and reading, plugin MCP registration with both history modes, plugin overrides, capability-root precedence and isolation, and restoring saved child settings after parent settings change.
GitOrigin-RevId: 2a6891a9bc6372fd2d1f30add2b5611f96b60594
Remove the obsolete `default_zsh_path` argument from the call to
`Config::rebuild_with_session_layers` in
`local_mxc_preference_preserves_configured_backend` to match its current
signature.
GitOrigin-RevId: ddb7a73535cc605917971b974333d69bf3a92a93
## What changed
Support `plugins._default.enabled` with explicit per-plugin `enabled` overrides. Omission preserves existing source and account enablement; configuration cannot activate a plugin disabled at its source. Plugin settings such as remembered tool approvals inherit the default unless `enabled` is explicitly set.
Apply the policy to plugin skills, MCP servers, Apps, and hooks, including selected executor roots and runtime configuration refreshes. Preserve the latest plugin policy when adding MCP dependencies and rebuild hooks when concurrent configuration updates replace their inputs.
Report effective enablement in `plugin/list`, `plugin/installed`, `plugin/read`, and `plugin/share/list`. Remote installation still installs disabled packages, but skips MCP and Apps authentication setup without writing an enablement override.
## Testing
Add regression coverage for default inheritance and explicit overrides, source-disabled plugins, policy refreshes during active turns, disabled or malformed selected plugin roots, and remote installation authentication behavior.

## What changed
- Add `ContentItemMetadata` to distinguish user input, developer instructions, `AGENTS.md`, skills, harness context, and tool-supplied context independently of message role and content classification.
- Keep attribution attached to content through prompt assembly, history processing, and hook-output spilling. Distinguish command hooks from MCP hooks and retain tool namespaces when known.
- Treat missing historical attribution as unknown and send per-content metadata only to Responses Lite.
## Testing
Update request and history assertions to cover attribution persistence and Responses Lite metadata handling.

## What changed
Add `windows.require_mxc` to managed requirements. When set to `true` on Windows, reject configurations whose effective local sandbox backend is not MXC without changing the selected backend.
Validate after cloud configuration loads and outside startup recovery fallbacks. Apply the check to app-server startup and configuration loads, in-process bootstrap, session creation, sandbox debugging, and runtime configuration refreshes.
## Testing
Extend configuration tests to cover required and optional MXC selection, separately loaded policy requirements, and runtime refresh validation. Expand app-server startup tests to cover local and cloud MXC requirements, cloud preference selection, and failures without default-config recovery.

## What changed
- Accept an optional `description` in `create_channel` and return it in channel summaries so agents can describe a channel's purpose.
- Enforce a limit of 512 UTF-8 bytes and account for JSON escaping in the output budget before creating the channel.
- Store descriptions in both board backends and migrate existing SQLite databases, leaving older channels without descriptions.
## Testing
Add coverage for UTF-8 byte limits, serialization, output budgets, legacy database migration, and persistence after reopening. Update the model-context scenario to create and list a described channel before posting and reading a message.

## Why
MCP servers receiving sandbox state need a usable Codex executable to launch commands with the issuing call's policy. HTTP and remote servers cannot assume access to the host's filesystem.
## What changed
- Include optional `codexExecutable` metadata for local stdio servers when the host supplies an absolute, UTF-8 path to a CLI supporting `sandbox --sandbox-state-json`. Cache capability probes by executable path and bound them to five seconds.
- Document forwarding the sandbox state unchanged and requiring an explicit opt-out rather than silently falling back to PATH lookup or unsandboxed execution when the launcher is absent.
- Honor `useMxc` from forwarded sandbox state when selecting the Windows sandbox backend and network proxy policies, preserving a parent's selection made through CLI overrides.
## Testing
Add coverage for launcher eligibility across local, remote, and HTTP servers, invalid or missing executable paths, and binaries without sandbox-state support. Extend metadata integration and serialization tests to cover the optional launcher field, legacy state, and unknown future fields.

## Why
GovCloud guidance was tied to Bedrock credential setup, so users with an already configured provider could miss it.
## What changed
Check for GovCloud during TUI startup using the app server's resolved provider, including when connecting to a server. Require acknowledgment before proceeding and save `notice.hide_gov_cloud_guidance = true` to suppress the screen on subsequent launches. Quitting the guidance exits startup without saving acknowledgment.
## Testing
Add a terminal integration test covering acknowledgment persistence, quitting without saving, and suppression after restart. Retain coverage for explicit acknowledgment and scrolling in short panes.

## What changed
Add `include_environment_context_time`, enabled by default. Setting it to `false` omits `<current_date>` and `<timezone>` while retaining the rest of the environment context, and skips the clock read used to populate the date.
## Testing
Extend configuration, session context, and external time provider tests to cover enabled and disabled time fields, context updates across turns, and current-time reminder behavior.
