## What changed
- Add a bounded developer context fragment identifying the MCP server or connector and the user-owned configuration that declared it.
- Emit the fragment only when the effective entry matches the user configuration or an active plugin declaration resolves inside the Codex home directory.
- Keep tool descriptions, outputs, and unrelated tools untrusted, and reject unsupported sources or paths that escape through symlinks.
## Testing
- Cover user-configured servers and connectors, plugin-provided capabilities, token truncation, symlink escapes, and app-server request integration.
GitOrigin-RevId: 0bfe2a2f3a48334d1d5faad692b5d36452febb68
## What changed
- Add the `write_stdin_approval` feature flag, disabled by default, to require a fresh approval before sending non-empty input to an escalated unified-exec terminal.
- Route these reviews through hooks, Guardian, app-server, and the TUI as `writeStdin` approvals while keeping the parent command item unchanged.
- Preserve the terminal environment, launch directory, and escalation state across turns, and revalidate the process identity after approval before writing input.
## Testing
- Cover approval routing, policy decisions, process reuse, terminal identity preservation, app-server events, analytics, and TUI rendering.
GitOrigin-RevId: 4ba29eaae6208e934737ba078c96e589c7c2164d
## Why
Models that require automatic review previously skipped Guardian v2 risk scoring
entirely, even when Guardian was limited to computer-use tools. That scope cannot
use a low-risk result to approve unrelated tools, so the blanket skip is
unnecessary.
## What changed
- Retain Guardian v2 risk scoring for required-review models in
`ComputerUseOnly` scope while continuing to skip it in standard scope.
- Preserve strict automatic approval review for Node REPL-backed tools, including
when classification fails.
## Testing
Added coverage for low-risk, high-risk, and invalid classifications across the
Node REPL and computer-use REPL paths, plus an unrelated MCP tool.
GitOrigin-RevId: ee38fabf82e196df0ae13b4216b5892be9b799cf
## What changed
Remove `minimum`, `maximum`, and `maxLength` from the supported tool input
schema representation. Schema parsing now drops these bounds instead of
including them in generated tool declarations, including declarations for
reserved history and notes tools.
GitOrigin-RevId: b7c7733651e65d38cc3d0cef2efa127ab3f8a32f
## What changed
- Resolve plugin activation, MCP server policy, and marketplace definitions from the effective configuration stack, including system settings and trusted project overrides.
- Load plugin skills independently for each working directory passed to `skills/list`.
- Exclude project configuration from catalog requests whose `cwds` are omitted or empty.
- Cache up to eight loaded plugin configurations with least-recently-used eviction so requests for different working directories can reuse their results.
## Testing
- Cover layered plugin and MCP policy across trusted and untrusted projects.
- Cover per-directory skill and plugin catalog results, cache reuse and eviction, and system-defined marketplaces.
GitOrigin-RevId: cb68b2b1bdab1da48e05ca7562bc05014431fc71
## Why
App-server clients need the explanation and steering instruction returned with a
misalignment policy violation to offer a user-confirmed continuation. Missing or
incomplete details must continue to behave as a terminal block.
## What changed
- Parse optional misalignment classification, explanation, and steering details
from streamed and HTTP Responses errors and propagate them through core errors.
- Include the details in live app-server `error` and `turn/completed` payloads and
export the corresponding protocol schemas and TypeScript types.
- Keep explanations and steering messages out of serialized rollout events and
redact them from debug output.
- Document how clients can resume with `turn/start` after user confirmation.
## Testing
- Cover streamed, HTTP, and WebSocket-wrapped errors, including malformed and
classification-only details.
- Verify live app-server notifications expose resumable details without writing
the explanation or steering message to the rollout.
GitOrigin-RevId: 329258a444c2cd91d0c57ab1720830b33ddcfac5
## What changed
- Classify `response.failed` events with the `rate_limit_exceeded` code as a distinct retryable error while preserving any parsed retry delay.
- Expose the error as `rateLimitExceeded` through the core protocol and app-server schemas after stream retries are exhausted.
- Preserve the upstream message for TUI display while keeping it out of telemetry summaries.
## Testing
- Cover SSE classification, retry metadata, protocol conversion and serialization, exhausted stream retries, telemetry redaction, and TUI rendering.
GitOrigin-RevId: 02dab4d3477dcd7653a58c49c4bd38687a616579
## What changed
- Append accepted Guardian V2 classification results to rollout history for non-ephemeral threads.
- Keep resumed and forked threads from restoring a persisted score into active Guardian state.
## Testing
- Verify that asynchronous scoring records the resulting `SecurityRiskScore` rollout item.
- Seed resume and fork tests with a persisted score and verify that approvals ignore it.
GitOrigin-RevId: 40d63a2ea7e7cf6398402c6aed7d5e5727dc9d68
## Why
Guardian approval reviews may need the original user instructions to decide
whether a command is authorized.
## What changed
- Forward the parent thread's `history.list_windows`, `history.list_items`,
`history.read_item`, and `history.search_contents` executors to Guardian
reviewer sessions.
- Keep other parent extension tools, including the `notes` namespace, isolated
from Guardian reviewers.
## Testing
Add an app-server integration test that reads parent history during a Guardian
review and verifies that `notes` tools are not exposed.
GitOrigin-RevId: 65a90036577050adfa23b1d98f862233c994d9d7
## What changed
- Default Guardian v2's review scope to computer-use tools. Set
`features.guardianv2.review_scope.computer_use_only = false` to retain the
broader tool review scope.
- Include images in Guardian transcripts by default. Set
`features.guardianv2.transcript.include_images = false` to disable them.
## Testing
- Update configuration and app-server coverage for the new defaults and
explicit broader-scope overrides.
GitOrigin-RevId: 88c3cfe6dd2a96df052111794ad59c5c9ea39b78
## What changed
- Express nullable history and notes arguments with `anyOf` and remove unsupported schema constraints.
- Forward valid JSON object arguments to the backend without enforcing client-side limits.
- Clarify history ID, ordering, cross-agent path, and consistency semantics in the tool descriptions.
## Testing
- Cover forwarding previously restricted argument values for every history and notes tool.
- Verify app-server requests expose the Bridge-compatible schemas and still reject non-object arguments locally.
GitOrigin-RevId: 28809fe9da5099944fd04962b5e71ffda4163eea
## What changed
- Convert unstructured MCP results into typed function-call output items instead of serializing the entire content array as a text string.
- Keep structured MCP results as serialized text and preserve media, encrypted content, and unknown content through their existing item conversions.
- Drop empty text items during output truncation so they do not consume API array slots.
## Testing
- Cover text-only, mixed unstructured, structured, and image-sanitized MCP results.
- Verify empty text items are discarded under byte- and token-based truncation policies.
GitOrigin-RevId: fa1c5b7dee6f003a094265379dcabdd060386a48
## Why
MCP servers attached to executor environments must retain their owner's
permission profile instead of inheriting the thread-wide sandbox authority.
## What changed
- Resolve and capture a permission profile for each enabled MCP server when
publishing the runtime, and reject calls or elicitations when that authority
is unavailable.
- Use the captured server profile for tool approval decisions, elicitation, and
sandbox metadata, including after runtime refreshes.
- Materialize `:workspace_roots` from `PathUri` values so permissions preserve
the path convention of remote executor environments.
- Give threadless app discovery and resource reads an explicit default
permission profile.
## Testing
Added coverage for per-server elicitation authority, unresolved attachments,
runtime refreshes, restricted tool calls, and foreign-platform workspace roots.
GitOrigin-RevId: 6b188d4b08b29e9971ff7aa68a7785a0cdf9e394
## Why
SQLite log persistence needs visibility into batch size, write latency,
failures, and entries dropped before they reach the writer. Exporter
diagnostics must not feed back into the SQLite log sink and keep metric
exports active indefinitely.
## What changed
- Record write count, duration, batch bytes, entry count, largest-entry size,
and queue drops with bounded outcome tags.
- Add explicit byte histogram boundaries for log batch metrics.
- Filter OTLP transport noise and the benign unsolicited HTTP/2 PING warning
from SQLite log persistence to prevent export cycles while retaining other
HTTP/2 warnings.
## Testing
- Cover metric values, tags, queue-drop reasons, and histogram boundaries.
- Verify successful and failed OTLP HTTP and gRPC exports become idle instead
of generating recurring SQLite log-write metrics.
GitOrigin-RevId: a63224ae15945fe84adc977a8b7d55bb47a4de53
## Why
Reserved tool parameter constraints must survive schema parsing so the model receives the declared limits.
## What changed
- Preserve `minimum` and `maximum` as exact JSON numbers.
- Preserve `maxLength` and infer a string schema when it is the only type hint.
## Testing
- Cover bounded integer, number, and string schemas through both parsing paths.
- Verify history and notes tools retain their constraints in app-server model requests.
GitOrigin-RevId: 4cc89722b5b226d595b57232ec3b8e825863faf3
## What changed
- Read `x-codex-imagegen-request-id` from image generation and edit responses.
- Propagate the ID to `codex_image_generation_event` analytics.
- Keep the ID in process only, excluding it from extension item serialization, generated types, app-server wire data, and rollout history.
## Testing
- Cover response-header extraction and missing-header behavior in the images client.
- Verify end-to-end analytics emission and the unchanged image-generation item wire shape.
GitOrigin-RevId: 9b8e09b7d655c0c2faa84f0eee99aabae583668d
## Why
Git remote URLs can embed usernames, passwords, or tokens. Codex carries these
URLs through turn metadata and persisted thread metadata, so credentials must be
removed before a remote enters those paths.
## What changed
- Add `SanitizedGitUrl`, which parses Git URL and SCP-style remotes, strips
authentication data, and preserves the conventional `git` SSH user.
- Use sanitized remotes when collecting Git metadata, enriching model requests,
discovering cloud environments, updating thread metadata, and reading legacy
rollouts. Reject or omit malformed remotes instead of retaining their raw
contents.
- Keep API, schema, and TypeScript representations as strings while enforcing
sanitization in Rust.
## Testing
- Cover URL schemes, SCP and IPv6 forms, remote helpers, encoded paths,
malformed values, and legacy deserialization.
- Verify credentials do not appear in model requests, API responses, SQLite, or
rollout files.
GitOrigin-RevId: 6435efc4c45bfbfad4723ce7a0457cb00175f25c
## What changed
- Accept only `http://` and `https://` gRPC endpoints for app server
`--code-mode-host` connections.
- Limit the standalone code-mode host to stdio and gRPC listeners.
- Remove the WebSocket session provider, dual-WebSocket negotiation, transport
lanes, and related dependencies and tests.
- Keep coverage for shared and prewarmed gRPC hosts and reject WebSocket host
URLs in CLI parsing tests.
GitOrigin-RevId: 8792604e79ffd54ce776074a4dc3f7d55e63752a
## Why
MCP servers can share an OAuth callback URL. Without a validated issuer or a
server-specific callback path, an authorization response could be associated
with the wrong server.
## What changed
- Use stable callbacks when authorization metadata advertises issuer-bound
responses, and validate the returned issuer before exchanging the code.
- Retain server-specific callback IDs for providers without issuer support,
including fallback to the global or default callback for legacy registered
clients.
- Persist registered callback URLs for MCP servers and plugins, and insert the
active listener port into portless loopback redirects.
## Testing
Add coverage for issuer validation, callback-mode discovery, registered and
legacy clients, plugin OAuth, CLI persistence, and loopback listener ports.
GitOrigin-RevId: 2878c92e237fc17fd3def0bd2e1cce3e104a3db8
## Why
Diagnostic uploads skip the doctor attachment if report generation exceeds its
overall timeout. SQLite integrity scans can be delayed by large databases or
lock contention.
## What changed
- Give each database integrity scan a one-second deadline when collecting a
diagnostic attachment.
- Interrupt scans and lock waits at the deadline, preserve any corruption rows
already returned, and report an incomplete clean scan as a warning.
- Keep direct `codex doctor` integrity checks unbounded.
## Testing
- Cover interrupted scans, lock waits, retries without a deadline, and
corruption results returned before interruption.
GitOrigin-RevId: 4817fb459ac53953669a9ba5f03397a6fc82c72e
## What changed
- Add the experimental `turn/start.cyberAccessProgram` option with `standard`,
`daybreakBlue`, and `daybreakRed` values.
- Forward the selection as `access_programs.cyber` on Responses, WebSocket,
and remote-compaction requests made with ChatGPT authentication, while
omitting it for API-key and custom-provider requests.
- Preserve the per-turn selection across recovery, compaction, and child-agent
turns without making it a persistent thread setting.
## Testing
- Cover app-server forwarding, authentication boundaries, WebSocket reuse,
turn recovery, compaction, and child-agent inheritance.
GitOrigin-RevId: d2eb468f365b2214c5099bc21741cf30f8bd2eb5
## Why
Removing a base-user marketplace must not delete a snapshot that is still
referenced by another enabled configuration layer.
## What changed
- Load the current configuration stack for marketplace commands in the CLI and
app server.
- Reject removal when a matching marketplace is defined by another enabled
layer, and identify the configuration source that must be updated instead.
- Allow cleanup of an installed marketplace snapshot even when no base-user
entry exists.
## Testing
Cover project, enterprise-managed, system, and session-flag configurations, as
well as snapshot-only removal through the CLI and app server.
GitOrigin-RevId: 4f0853a40c2b5fae0410696b79eee4284239c7a9
## What changed
- Add the opt-in `code_mode_prewarm` feature to establish the code-mode host session during startup, before the first turn.
- Make in-progress host initialization cancellable so a stalled prewarm does not block shutdown.
- Share a failed connection attempt with concurrent callers instead of immediately starting another attempt.
## Testing
- Verify app-server contacts the configured host before the first turn and can shut down while that connection is stalled.
- Exercise shared remote-host behavior with prewarming enabled.
GitOrigin-RevId: 3cfde5509be7b4aba80112c36c5616b9a9b632c6
## What changed
When `thread/start` omits `historyMode`, select `paginated` for durable
threads whose store supports `thread/turns/list` and `thread/items/list`.
Continue to default ephemeral threads and threads backed by stores without
those APIs to `legacy`.
Explicit `legacy` and `paginated` selections keep their existing behavior.
## Testing
- Verify durable threads use paginated history with the local store.
- Verify ephemeral threads and stores without history-list support use legacy
history.
GitOrigin-RevId: c94b6a3b522049d541da33c41618c4142370f1a7
## Why
Paginated thread history should be loaded incrementally through
`thread/turns/list` and `thread/items/list` instead of being fully reconstructed
in `thread.turns`.
## What changed
- Emit `deprecationNotice` when `thread/read`, `thread/resume`, or `thread/fork`
requests full history for a paginated thread.
- Direct clients to omit `includeTurns` for reads or use `excludeTurns: true` for
resumes and forks, then page history through the list APIs.
- Document the deprecation in the protocol schemas and app-server README.
## Testing
- Cover notices for paginated reads, cold and loaded resumes, and forks.
- Verify metadata-only requests, legacy threads, and rejected forks do not emit
the notice.
GitOrigin-RevId: 0d387b46d73608f90b7960120a54af4ef332e510
## What changed
- Make `thread/turns/list`, `thread/items/list`, and `thread/revert` available
without the experimental API capability.
- Stabilize `thread/reverted`, `thread.historyMode`, and the pagination fields
used by `thread/resume` and `thread/fork`.
- Publish the promoted requests, responses, and fields in the stable JSON and
TypeScript schemas, and update the app-server documentation accordingly.
GitOrigin-RevId: 18b8c53c265211597bb1a62fd62f66f4a3df5f06
## Why
App-server clients can enable `background_paginated_rollout_migration` after the server has started, so the startup-only migration path does not handle that transition.
## What changed
- Allow runtime enablement of `background_paginated_rollout_migration`.
- Start the local rollout migration when the feature transitions from disabled to enabled at runtime.
## Testing
Update the app-server integration test to enable migration through the runtime feature API, wait for paginated history, and verify that cold resume preserves model context.
GitOrigin-RevId: d695624a03b4f056be94fcaac2075f91896f19e5
## What changed
- Add an optional `turnTrigger` field to app-server `turn/start` requests and
expose it in the generated protocol schemas.
- Propagate non-empty trigger values to Responses request metadata as the
reserved `turn_trigger` field, while preserving the original value when a
request steers an active turn.
- Classify turns started by queue dispatch, goal continuation, retry recovery,
and realtime handoff.
## Testing
- Cover HTTP and WebSocket metadata forwarding, steering behavior, reserved
metadata handling, and the built-in trigger classifications.
GitOrigin-RevId: c12fe2c522286db21b76081ae6154fbf6bfb3639
## What changed
- Add the experimental `turn/settings/update` method for changing `model`,
`effort`, `summary`, and `serviceTier` on a specific live turn without
changing future turns.
- Report whether the update was applied or the target turn was unavailable,
and reject unsupported fields, disabled feature use, unsafe model changes,
and direct updates to parent-owned subagents.
- Document the method's feature requirements, null handling, and limits.
## Testing
- Cover current-turn and future-turn isolation, rejected and unavailable
targets, feature and capability gates, saved threads, and subagent ownership.
GitOrigin-RevId: 18440f6d7ee5fcd06ae23bd41b22c492b62bb2b5
## Why
Selected executor plugin roots could still expose capabilities when managed
requirements disabled the `plugins` feature.
## What changed
- Suppress MCP servers, skills, apps, and connectors from selected executor
plugins when `plugins` is disabled, while preserving the selected-root
identity used to filter those capabilities.
- Apply the policy consistently to direct selected-root discovery and batched
executor capability discovery.
## Testing
- Add contributor-level and app-server coverage that verifies disabled plugin
capabilities are absent and their MCP servers never start.
GitOrigin-RevId: e30bd8a936c4b0e083908b89a65f4d02e01747de
## Why
Answers collected by `request_user_input` can change what the user authorizes, but post-tool hooks may replace or reject the tool output that Guardian normally sees.
## What changed
- Record bounded, host-observed answers before post-tool hooks run and provide them as trusted evidence to synchronous and asynchronous Guardian reviews.
- Include root-thread answers in worker review context.
- Count successful answers as authorization changes so earlier review evidence becomes stale, while ignoring empty or unrelated answers.
## Testing
Add coverage for allowed and denied stale reviews, empty and oversized answers, hook-modified output, and root-to-worker propagation.
GitOrigin-RevId: 970c52e40338ecd057c7cd2a69d04b06e97cd068
## What changed
- Add `serviceTierForTurn` to `turn/start` so a newly started turn can override the service tier without changing the thread's saved tier.
- Treat `"default"` as standard speed and omitted or `null` values as inheriting the thread tier.
- Keep `serviceTier` authoritative for subsequent turns when both fields are supplied, and ignore the turn-scoped override when steering an active turn.
## Testing
- Extend the app-server turn-start test to verify both the one-turn `"default"` override and inheritance on the following turn.
GitOrigin-RevId: 4c2c4db21d8d31617a7a6e6df65bf54834e72383
## What changed
- Record collaboration tool analytics for `send_message`, `followup_task`,
`interrupt_agent`, and `list_agents`, including receiver attribution, duration,
failures, and interrupted calls.
- Include these calls in per-turn subagent tool counts while keeping the existing
`subAgentActivity` output unchanged and omitting additional public collaborator
tool items.
- Extend the collaboration tool schemas with the new tool variants and the
`interrupted` terminal status.
## Testing
- Add an app-server integration test covering successful and failed calls,
receiver attribution, duration, prompt omission, activity items, and turn
counts.
GitOrigin-RevId: e73eaa05c508261e5fc97e7d08d7881a31e04e22
## What changed
- Register the history-notes extension as a context contributor and fetch `thread_hint` from the configured history-notes backend.
- Add non-empty hints of at most 4,000 bytes to the context-window prompt, and omit hints when the request fails or the response is missing, empty, or oversized.
- Verify that app-server sessions use the native backend when `use_history_notes_extension` is enabled and retain the MCP bridge behavior when it is disabled.
## Testing
- Cover hint injection, request context, response validation, backend failures, and disabled-extension behavior in history-notes and app-server tests.
GitOrigin-RevId: 344a7bb79d962ea8b7c969f25b67a79423fc7fcc
## What changed
- Add a `writeStdin` Guardian action carrying the approval, process, input, and working-directory details.
- Distinguish `command` and `writeStdin` execution approval requests while defaulting missing kinds to `command` for compatibility with older events.
- Render terminal-input review progress, denials, timeouts, and retry actions in the TUI, and record the action separately in analytics.
- Keep terminal-input reviews as child approvals so they do not change the parent command item's lifecycle or reconstructed history.
## Testing
- Cover Guardian serialization, app-server protocol conversion, command history reconstruction, analytics classification, and TUI review flows for terminal input.
GitOrigin-RevId: b083d5e2963bdd23b928644ec03c7eb68ebf2950
## What changed
- Add an `Interrupt` hook event that runs for an active top-level turn before its
interrupted abort event is emitted.
- Flush the turn transcript before invoking the hook and provide the session,
turn, transcript, working directory, model, and permission mode in its input.
- Support command and MCP handlers, including asynchronous commands, with a
one-second default timeout and a three-second maximum.
- Expose the event through hook configuration, managed requirements, app-server
notifications, generated schemas, analytics, and the TUI hook views.
## Testing
- Cover handler discovery, timeout normalization, output parsing, protocol
compatibility, TUI rendering, and interrupt execution ordering.
GitOrigin-RevId: 163fa7c098d94ac2775f6d137f8e916f8ea9b6eb
## Why
Clients need a bounded view of realtime conversations that preserves the order of speech, agent work, and turn lifecycle events without loading the full thread history.
## What changed
- Persist realtime session boundaries, transcript segments, and promoted agent items in paginated thread rollouts.
- Add the experimental `thread/timeline/list` API to page ordinary items, realtime items, and turn boundaries in canonical rollout order. Include `activeRealtimeSessionAtPageStart` so each page can be rendered independently.
- Emit typed `thread/realtime/item/started`, `thread/realtime/item/transcript/delta`, and `thread/realtime/item/completed` notifications around durable realtime items.
- Keep the existing `thread/items/list` response and legacy thread history behavior unchanged.
## Testing
- Cover mixed timeline pagination, realtime-session state at page boundaries, rollout replay, subagent history prefixes, transcript streaming, steering, and promoted agent artifacts.
GitOrigin-RevId: faa2c420192d63e060e8fb32446e3c797422656e
## Why
Unified `@` search could show a plugin alongside the skills it owns, creating duplicate entry points for the same capability.
## What changed
- Add a nullable `pluginId` to `SkillMetadata` returned by `skills/list` so clients can associate skills with their owning plugin without inspecting names or paths.
- Hide a plugin's owned skills from unified `@` results when that plugin is present, while retaining standalone skills and skills with unknown ownership.
- Keep `$` focused on individual skills and apps, and use it consistently as the skills-list shortcut. Preserve the legacy mention behavior when `mentions_v2` is disabled.
## Testing
- Cover plugin ownership in `skills/list` and the updated `@` and `$` composer results.
GitOrigin-RevId: e168cdff8d0c58f74ce4c228a683880a3167775b
## What changed
Change the background model refresh interval from 3 minutes to 4 minutes 30
seconds.
GitOrigin-RevId: dcefe471c91dc94a04ddc74595c3ce00d9061e55
## What changed
- Emit control-tool analytics for history and notes extension calls and for
`send_user_message_async`.
- Preserve non-default namespaces in reported tool names, such as
`history.read_item` and `notes.write_file`.
## Testing
- Add an app-server integration test covering successful and failed calls,
turn-level tool counts, and omission of tool argument values from analytics.
GitOrigin-RevId: b15a53a311228339f4d577a7b96146ed67f22253
## Why
`skills.read` paginated resources against a fixed response limit, so a page could exceed a smaller tool-call response budget.
## What changed
- Size each serialized `skills.read` page to the current call's response budget, accounting for JSON escaping and UTF-8 boundaries.
- Cache one bounded executor-resource snapshot per thread so cursor continuations return consistent contents without rereading the file. Replace the snapshot when another resource is read, and reject stale cursors after a reread.
- Tie cached executor snapshots to the selected environment and sandbox context without keeping the environment alive.
## Testing
- Cover budget-constrained reads, escaped and multibyte contents, multi-page reconstruction, changed resources, snapshot eviction, and expired turn-scoped access.
GitOrigin-RevId: e515935b82771b3f29b3fb91ea7a7a72e19a65ee
## What changed
- Emit `codex.turn.cost_microusd` as a counter with turn, conversation,
interruption, speed, and reasoning-effort attributes. Convert the estimated
USD string to microdollars, rounding to the nearest microdollar and skipping
values that cannot be represented safely.
- Start turn-cost collection when an OTLP metrics exporter is configured, even
when the OTEL log exporter is disabled.
## Testing
- Verify cost conversion, rounding, and metric attributes with an in-memory
metrics snapshot.
- Verify that a metrics-only OTLP configuration starts the turn-cost worker.
GitOrigin-RevId: e60587079f097f10cc1b6d1bf889d3f7a0dc3d5f
## Why
Analytics need to associate subagent activity with the top-level turn that
caused it, while avoiding a stale association when steering makes that origin
ambiguous.
## What changed
- Add `root_turn_id` to turn and tool-item analytics events.
- Read the root from live turn metadata when each event is built, reporting
`null` when the root is unknown or ambiguous.
- Propagate the metadata through control-tool and code-mode completion facts so
correlated and background tool events retain the correct root.
## Testing
- Cover root IDs for top-level turns, subagent turns, correlated code-mode
calls, and tool events emitted after turn completion.
- Verify that queued and subsequent events report `null` after the live root is
invalidated.
GitOrigin-RevId: 42fd76541c3c716cec74787d47b50adb2d22e6d2
## What changed
- Add the experimental `amazonBedrockAccessKeys` app-server login flow, persist its credentials in the configured auth store, and use them for SigV4-signed Bedrock requests.
- Report `bedrockAccessKeys` as a distinct auth mode and document access-key login alongside AWS profile and environment credential setup.
- Clear the selected Bedrock provider, AWS settings, and Bedrock-specific model on logout while leaving external AWS credentials and `.env` untouched.
- Reject managed access-key login when higher-precedence configuration would prevent its region or profile settings from taking effect.
## Testing
- Cover access-key login, storage, request signing, configuration conflicts, status reporting, and logout cleanup.
GitOrigin-RevId: bbf297887c6503d3651ceb2aad85c4d626e32723
## What changed
- Add `features.guardianv2.review_scope.computer_use_only` to restrict asynchronous classification and fast approvals to browser and computer-use REPL tools.
- Keep other tools on the synchronous approval path without letting them age or reuse scores from in-scope calls.
- Give this scope precedence over `sandboxed_exec_commands` when both options are enabled.
## Testing
- Cover configuration precedence, direct and code-mode tool detection, fast-approval isolation, and end-to-end approval routing for browser, computer-use, and unrelated MCP servers.

## Why
Multi-Agent V2 children are owned by their parent at runtime. Resuming an
unloaded child directly could rebuild it from caller-provided settings instead
of the parent's current authority.
## What changed
- Route child reloads through their loaded immediate parent and reject direct
cold resume when that parent is unavailable.
- Preserve the child's recorded model, provider, reasoning effort, and role
while inheriting the parent's execution policy and MCP extensions.
- Validate cached environments against the parent, intersect local permission
profiles, and reject stale remote or workspace-root configurations.
- Keep paginated cold-resume token usage attribution when attaching to the
reloaded child.
## Testing
Add coverage for owner validation, nested-parent reloads, permission and
environment changes, role instruction restoration, paginated usage replay,
and app-server child resume behavior.

## What changed
- Add `features.network_proxy.credential_broker` and preserve structured network proxy settings when toggling the feature through config APIs.
- Protect broker enablement and provider context variables from project config, while carrying trusted context into filtered shell environments.
- Propagate brokered credentials through shell snapshots and restore real credentials for unsandboxed escalated commands.
- Normalize broker context environment keys case-insensitively on Windows and avoid conflicting remote managed-network enforcement when no proxy launch configuration is available.
## Testing
- Cover config layering, editing, project sanitization, Windows environment handling, shell snapshots, escalated execution, and end-to-end GitHub credential brokering in the zsh-fork runtime.

## What changed
- Track truncation and omission across Guardian v2 actions, transcript entries and images, and synchronous review evidence.
- Emit `codex.guardian_v2.classification.truncation` counters and byte histograms for original, retained, and omitted content after successful classifications.
- Tag observations by input component and whether content was truncated or fully omitted.
## Testing
- Extend async scorer coverage for action truncation metrics.
- Verify the app-server Guardian flow records truncated review evidence.

## Why
Parent-owned Multi-Agent V2 subagents must remain controlled by their parent,
but several app-server endpoints could still mutate them directly.
## What changed
- Centralize the direct-input ownership check and apply it to turn injection,
MCP calls, reviews, compaction, rollback and revert, shell and Guardian
actions, realtime requests, and goal mutations.
- Enforce the same policy for goal mutations on unloaded threads while keeping
goal reads and turn interruption available.
- Document the affected endpoint behavior and continue exposing
`canAcceptDirectInput: false` for parent-owned subagents.
## Testing
- Cover direct-input rejection for both legacy and paginated thread history.
- Cover goal mutation ownership checks for unloaded V2 subagents, V1
subagents, and non-subagent V2 threads.

## Why
A Multi-Agent V2 child can finish after the parent turn that spawned it, so its
successful completion needs to remain associated with that parent turn in
notifications and history.
## What changed
- Add `completed` to `SubAgentActivityKind` and emit the corresponding started
and completed item events on the spawning parent turn when a child succeeds.
- Persist completed activity as a canonical turn item in both legacy and
paginated history, and expose it through app-server history and schemas.
- Render completed activity as terminal in the TUI without counting it as a
separate tool call or tool-runtime event.
## Testing
- Cover successful completion in legacy and paginated history, late updates to
completed parent turns, TUI rendering, analytics, and rollout tracing.
- Verify that terminal child errors do not emit completed activity.
