## What changed
- Execute `mcp_tool` hook handlers through the session's shared MCP runtime, including managed hook configurations.
- Restrict hook calls to already-connected, cataloged, and policy-allowed tools. Unavailable servers fail immediately without starting or reconnecting them.
- Pass session metadata to hook tools, cap hook timeouts by the server timeout, and invoke hooks without model-tool approval or recursive hook dispatch.
- Record handler type and execution mode in hook telemetry, and mark memory as externally influenced after successful or blocking MCP hooks when configured.
## Testing
- Added end-to-end coverage for prompt interpolation, hidden tools, blocking decisions, unavailable servers, thread metadata, approval bypass, and memory-mode handling.
- Added MCP runtime coverage for startup readiness, tool filters, catalog revisions, and managed connector policy.

## Why
`codex-http-client` is the intended owner of `reqwest`, while direct first-party
dependencies are tracked as migration debt.
## What changed
- Build app-server test HTTP clients through `HttpClientBuilder`.
- Use `http` and `url` types directly where only protocol types are needed.
- Remove `reqwest` from `codex-app-server` and its temporary dependency-policy
exception.
GitOrigin-RevId: ff9f14a54bc20ec1ea39050bbe08c381ee376119
## Why
Submitting a diagnostic report could appear successful without confirming that Sentry accepted the upload, leaving callers unable to detect transport or HTTP failures.
## What changed
- Send report envelopes through the route-aware HTTP client and await the response.
- Reject redirects, propagate transport and non-success HTTP responses, and include the full error chain in upload JSON-RPC errors.
- Add structured logs for upload attempts, successes, and failures without including report contents.
## Testing
Added coverage for successful uploads, rejected responses, blocked redirects, transport failures, and app-server JSON-RPC error reporting.
GitOrigin-RevId: 07b5cfccd7a65f35d51a720537d2cd8962ed6cdb
## What changed
- Replace the minimal default classifier prompt with predictive security-review guidance covering authorization, action risk, untrusted evidence, and browser or computer use.
- Trigger full Guardian review at an `action_risk` score of `0.5` or higher for the new default prompt, while retaining the `0.8` calibration for custom and model-provided prompts unless they specify a threshold.
- Render security policy configuration into prompt templates before enforcing the classifier instruction token limit. Prompts without the policy placeholder retain the existing append-and-truncate behavior.
## Testing
- Cover default, custom, and model-provided prompt thresholds and precedence.
- Verify policy substitution, truncation, sampling requests, and full review at the threshold boundary.
GitOrigin-RevId: 7aad9e2d8c9fbea453dc52147a3d0a46bf191aec
## What changed
- Add an optional `connectorId` to `mcpServer/resource/read`.
- Forward the selected connector through `x-codex-turn-metadata` for threaded and threadless resource reads, restricting hosted app resources to that connector.
- Update the generated protocol schemas and app-server documentation.
GitOrigin-RevId: 5cc94d703abbbb6086665910c1c9ed5dc7075210
## Why
Repository-scoped imports must not follow redirected Codex paths and write
generated configuration outside the repository.
## What changed
- Reject repository migration scopes when generated configuration paths are
symlinks or, on Windows, reparse points.
- Recheck hook and subagent destinations during import, skipping redirected
directories, files, and dangling links without reporting them as imported.
## Testing
Add service and app-server coverage for redirected generated destinations,
including a repository path replaced with a symlink after detection.
GitOrigin-RevId: 3afb521ead9d76250f0e967eccfdd1dc194f027a
## Why
Compaction can remove the tool-call events that associate an MCP app widget with
the tool, account, and URI needed to authorize later resource reads.
## What changed
- Store a bounded MCP resource-origin checkpoint with each compacted rollout.
- Restore the checkpoint when resuming a session so existing widgets remain
readable after compaction and restart.
- Discard saved origins when rollback rewrites history across the compaction
boundary, and reject oversized or invalid checkpoints during restoration.
## Testing
- Extend the app-server MCP resource-origin test to compact a paginated thread,
continue the conversation, and read the original widgets before and after a
restart.
- Verify rollback clears provenance that no longer matches retained history.
GitOrigin-RevId: 7f91c6202fe8d9be21c78dda42fa205937c44263
## Why
App widgets need to read resources using the app and account context of the
tool call that produced them, including after a thread is restored.
## What changed
- Add an optional `originCallId` to `mcpServer/resource/read` requests and
return it on successful scoped reads.
- Track bounded provenance for successful app tool calls in thread history and
use the current tool binding, account link, and app policy when reading the
associated widget resource.
- Reject missing, mismatched, failed, or ambiguous origins, while keeping
app-only tools available for widget reads without exposing them to the model.
## Testing
Add app-server coverage for scoped widget reads across both history modes,
ephemeral and persistent threads, server restarts, app-only visibility, and
invalid origin cases.
GitOrigin-RevId: 11eaefc066b2a3b639599e4cbdef680233d150a2
## Why
Repository manifests and user-configured sources must not be able to claim names reserved for managed or remote marketplaces.
## What changed
- Reject reserved marketplace names from unmanaged sources during discovery, installation, configuration projection, and configured marketplace upgrades, even when source restrictions are disabled.
- Recognize managed marketplaces only at their expected paths. Preserve the required macOS and Windows path equivalences without allowing symlink aliases to inherit managed provenance.
## Testing
- Cover reserved-name rejection for plugin list and install RPCs, configured upgrades, unrestricted policy, and remote marketplace names.
- Cover symlink spoofing and Windows managed-path normalization.
GitOrigin-RevId: a610bdc382857f306dd3e244f0992de2ec279673
## What changed
- Add the experimental `autoApprovalReview/strictReviewRequired` app-server notification with the review's `threadId`, `turnId`, and `startedAtMs`.
- Emit it when Guardian v2 leaves an approval review in progress because the action risk is elevated or its score is stale.
- Export the notification through the Rust, TypeScript, and JSON schema surfaces and route it to the associated thread.
## Testing
- Cover strict-review reason tracking for elevated and stale risk scores.
- Verify that high-risk approval routing emits one notification whose identifiers and timestamp match the review-started event.
GitOrigin-RevId: e65352894520bfb756c75b2c95e2e149f9767bb2
## Why
Cold resumes and forks could lose the thread's active permission profile and
fall back to the current configured default.
## What changed
- Restore the latest persisted approval policy, approvals reviewer, and active
permission-profile ID when resuming or forking a thread.
- Re-resolve persisted profile IDs through current configuration and
requirements. Missing or invalid profiles fall back to the configured
default, while threads without a persisted profile continue to use current
configuration.
- Keep explicit permission and approval overrides ahead of persisted settings.
## Testing
Added coverage for legacy and paginated histories, settings updates, explicit
overrides, removed or changed profiles, requirement fallbacks, and forks.
GitOrigin-RevId: 2289af2f3206bf131a6ffe0e8447e8d402e76c47
## What changed
- Fetch recommendations from the Codex-specific `/ps/plugins/suggested/codex` endpoint and parse its compact response shape.
- Fetch the selected plugin's details before presenting an install request, using them to verify availability and populate connector metadata.
- Skip install elicitation when the selected recommendation is no longer available, and return a retryable response when its metadata cannot be verified.
## Testing
- Cover the new recommendation route and response shape.
- Cover metadata hydration for available plugins and rejection of unavailable plugins.
GitOrigin-RevId: 2b0e2d70572aae2b7cd8e458b42e9dd14be3dbaf
## What changed
- Add `cli_auth_credentials_store` and `chatgpt_base_url` as exact managed requirements loaded from local requirements configuration.
- Apply these requirements to runtime and bootstrap authentication configuration, overriding user-configured values.
- Expose the managed values through `configRequirements/read` and reject attempts to change them through config write APIs.
- Ignore these local-only authentication requirements in cloud-managed requirement layers.
## Testing
- Cover requirement loading and composition, runtime and bootstrap overrides, app-server responses, and read-only config writes.
GitOrigin-RevId: 8ea9c096386072036ca5441f3d48af8707988a65
## Why
Unified exec could drop network approval registration when a selected environment used a Windows working directory on a non-Windows host because the trigger path could not be converted to a host absolute path.
## What changed
- Keep network approval trigger working directories as `PathUri` values and render them with their inferred native path syntax for Guardian requests.
- Fall back to the selected turn environment only when a trigger path can be converted to a host absolute path.
- Reject selected environment working directories larger than 8 KiB at the thread-manager validation boundary.
## Testing
- Cover managed-network approval registration for a foreign Windows working directory.
- Verify that oversized working directories are rejected as invalid `thread/start` requests.
GitOrigin-RevId: 646fbf12115a35a7e5cb04b511464797bee6647b
## Why
Resumed and forked threads need their persisted Guardian risk state available when routing later approval requests.
## What changed
- Initialize a session's `SecurityRiskScore` from the latest score in its rollout history when no score was supplied explicitly.
- Preserve the inherited score when resuming or forking a thread so low-risk actions can skip redundant Guardian reviews.
## Testing
- Add app-server coverage for inheriting the latest Guardian score when resuming and forking threads.
GitOrigin-RevId: 95a6c803f8dae75516d1da9d66a722379a0a7ef2
## Why
Config reads arriving while a long-running shared read was active waited for that
request to finish, even though they could safely run concurrently.
## What changed
- Admit newly queued shared reads into the active batch until an exclusive write
is queued, preserving the write as a fairness barrier.
- Treat `hooks/list` and `configRequirements/read` as shared config reads.
- Cover concurrent reads, read/write ordering, and config reads completing
alongside a `skills/list` request.
GitOrigin-RevId: 8194301c2ba60be0fc71b8915923af9accc745dc
## What changed
- Add end-to-end app-server tests for MCP tool approvals with Guardian V2 and automatic review enabled.
- Verify that sampling receives the thread context, uses a thread-scoped prompt cache key, and persists the resulting action risk score.
- Cover both routing outcomes: low-risk actions skip later Guardian reviews, while high-risk actions continue through full review.
GitOrigin-RevId: 78ba2b0560caf701ad333785c4dda4f7d2be4f2c
## Why
Guardian V2 should not override a managed approval-reviewer policy that excludes
the user reviewer.
## What changed
- Force `features.guardianv2` off when `allowed_approvals_reviewers` does not
include `user`, for both local requirements and cloud config bundles.
- Preserve Guardian V2 when the user reviewer remains allowed or when only
legacy Guardian feature settings are present.
- Return the effective disabled value through `config/read`.
## Testing
Added coverage for cloud requirements and the app-server config RPC.
GitOrigin-RevId: 82b6d0aaf47fbaa58ae349d4e56777cd442f5807
## What changed
- Stop fetching the ChatGPT workspace `enable_plugins` setting.
- Let the effective Codex feature configuration control app and plugin APIs,
plugin-provided skills and hooks, and experimental feature reporting.
GitOrigin-RevId: 46aebf0f07cd47e093e48663e41207cdf9a38c9f
## What changed
- Add optional `guardian_v2` model-message defaults for classifier instructions,
review thresholds, reasoning effort, transcript selection and limits, and
action and compaction token limits.
- Apply those defaults when Guardian v2 samples a tool call, while preserving
explicit `[features.guardianv2]` settings over catalog values.
- Preserve the new catalog configuration when applying model overrides.
## Testing
- Cover model-catalog serialization and model override behavior.
- Verify that sampling uses catalog defaults while retaining local overrides.
GitOrigin-RevId: 4ae9ec235c647acbca05a20b7c4b87a4e1331161
## Why
App-server request deserialization otherwise ignores unknown fields, so clients using the removed `permissionProfile` field could have their requested permission settings silently ignored.
## What changed
- Reject `permissionProfile` with an invalid-params error on `thread/start`, `thread/resume`, `thread/fork`, and `turn/start`.
- Direct clients to select a named profile through `permissions` instead.
- Continue accepting unrelated unknown fields for forward compatibility.
## Testing
- Cover rejection of the obsolete field on all four affected methods and verify that the connection remains usable.
- Cover successful `thread/start` requests that combine named `permissions` with an unknown field.
GitOrigin-RevId: a63764fb899bc5f212d60617dc32e911bde8073e
## What changed
- Discover synchronous `mcp_tool` hook handlers and invoke their configured MCP server and tool through a supplied executor.
- Expand nested hook-event placeholders in MCP tool inputs while preserving JSON types, and process tool output through the existing hook output contract.
- Represent hook details as handler-specific metadata in `hooks/list`, including MCP server and tool fields, and show those details in the TUI hooks browser.
- Skip unsupported `SessionEnd` MCP hooks and runtimes without MCP invocation support with startup warnings.
## Testing
- Cover argument expansion, missing placeholders, MCP invocation and hook decisions, discovery warnings, `hooks/list` metadata, and TUI rendering.
GitOrigin-RevId: 295b845471fe92bd7ad7cd272fbcd2c3713912e0
## What changed
- Rebuild hook runtimes for loaded sessions when effective plugins change or a marketplace upgrade installs new plugin content.
- Refresh plugin-related caches and MCP runtimes alongside hooks after plugin mutations.
- Preserve each loaded session's current configuration while rebuilding its hooks.
## Testing
- Cover direct plugin upgrades, including subsequent turn and session-end hooks.
- Cover automatic marketplace upgrades for an already loaded session.
GitOrigin-RevId: fef64c68d652f300c7f3d88e81c5017459aa9a18
## What changed
- Recognize `misalignment_policy_violation` errors from response streams and HTTP 400 or 403 responses.
- Preserve the upstream message, use a fallback for blank messages, and treat the error as non-retryable.
- Expose `misalignmentPolicyViolation` through the app-server protocol and generated schemas so turns fail with a typed terminal error.
## Testing
- Cover streamed and HTTP policy violations, fallback messages, retry behavior, and app-server turn completion.
GitOrigin-RevId: fd3485bf0be7bfe3d51c078bbc36a081692fd57f
## What changed
- Add model-catalog messages for root and subagent roles, explicit delegation, and delegation hints.
- Resolve role instructions in config, catalog, then bundled-default order, while preserving empty values as an explicit way to suppress fallback text.
- Refresh catalog-provided role and mode instructions when the model changes, and give full-history forks the selected child model's subagent role without retaining the parent's role guidance.
- Keep existing config overrides and reasoning-effort behavior, including proactive delegation for ultra reasoning effort.
## Testing
- Cover message deserialization and preservation through model overrides.
- Cover precedence, empty overrides, model switches, resumed sessions, and full-history subagent forks.
GitOrigin-RevId: 4625cf7c6a5490176adddfaa0fb99100707daea9
## What changed
- Set `parallel_tool_calls` for regular and remote compaction prompts without consulting model metadata.
- Remove `supports_parallel_tool_calls` from `ModelInfo`, the bundled model catalog, and related fixtures.
- Preserve the existing Responses Lite behavior that disables parallel tool calls at request construction.
GitOrigin-RevId: 49552bdf97e71fa57325abb49f8adc0c88f1401a
## What changed
- Add the built-in `amazon-bedrock-runtime` provider for regional
`bedrock-runtime` OpenAI-compatible endpoints.
- Use endpoint-specific SigV4 service configuration while preserving bearer
token auth and per-provider AWS profile, region, and transport overrides.
- Provide global and US cross-region GPT-5.6 model variants, prefer global
routing for fallback and background tasks, and disable unsupported web search.
## Testing
- Cover provider configuration and capabilities, endpoint and auth selection,
runtime catalog ordering, model fallback, and web search omission.
GitOrigin-RevId: d158ab74a5768e1b4c61063365a0c06735313322
## What changed
- Add experimental `thread/queue/add`, `list`, `update`, `delete`, `reorder`, and `start` requests for persistent queued user submissions.
- Automatically dispatch queued submissions in FIFO order after completed or failed turns, while leaving the queue paused after interruption.
- Emit `thread/queue/changed` notifications and expose paginated queue contents with stable submission and client message IDs.
- Export the new protocol types through the generated JSON Schema and TypeScript bindings.
## Testing
- Add app-server integration coverage for capability gating, CRUD, pagination, capacity limits, notifications, automatic dispatch, cold-thread resume, interruption, and explicit queue starts.
GitOrigin-RevId: 89caf5577192199bda77cf6c372a59d26cdd910e
## What changed
- Parse the optional `retirement_at` RFC 3339 value from model upgrade metadata, treating missing, null, or malformed values as unknown.
- Expose known retirement times from `model/list` as nullable Unix timestamps in `upgradeInfo.retirementAt` and preserve them when converting app-server models back into model presets.
- Update the generated protocol schemas and app-server documentation.
## Testing
- Cover absent, null, valid, and malformed catalog values.
- Verify `model/list` serialization and app-server model conversion for known, missing, and out-of-range timestamps.
GitOrigin-RevId: 969baf9f5b012997f460fb4611ba63c963ee658c
## What changed
- Add `oauth.callback_port` to MCP server configuration and preserve it when
serializing configuration edits.
- Accept `oauth.callbackPort` from plugin MCP declarations and skill dependency
metadata.
- Prefer the server-specific callback port over `mcp_oauth_callback_port` for
CLI login, app-server, plugin installation, executor, and skill dependency
OAuth flows.
## Testing
- Cover configuration parsing, serialization, and fallback behavior.
- Verify plugin, executor, and skill OAuth registrations use their configured
callback ports instead of the global port.
GitOrigin-RevId: 7f65e5e7869358307e49779f1b75e8672b607736
## What changed
- Wrap injected current time reminders in `<current_time_reminder>` tags.
- Keep direct `clock.curr_time` tool output and log previews as plain text.
## Testing
- Update core and app-server coverage for tagged reminders and untagged tool output.
GitOrigin-RevId: ad27f1fa10cca7f83d1ac731e01255320bb60f47
## What changed
- Add the experimental `thread/revert` request, which replaces a loaded paginated thread's durable history with the prefix before `beforeTurnId` while preserving the thread ID.
- Interrupt any active turn, reload the replacement history without unloading the thread, preserve mutable thread settings, and emit `thread/reverted`.
- Return backward pagination cursors for the retained turns and items, reject stale rollout paths after a revert, and document that local file changes are unaffected.
## Testing
- Cover history replacement, pagination, stale paths, missing turns, subsequent turns, active-turn interruption, and preserved thread settings.
GitOrigin-RevId: 435a8163ad4f310cc47219b436f6bdde21f2b83a
## What changed
- Keep the configured `approvalPolicy` when a model in
`auto_review.required_on_models` selects the `auto_review` reviewer.
- Continue downgrading full-access sessions to workspace-write and rejecting
incompatible reviewer overrides.
## Testing
- Cover supported approval policies across thread start, settings updates,
turn-time model switches, resume, and fork flows.
GitOrigin-RevId: 2bd3e2dcd46f3cadeb2fad20222cf8917c267208
## Why
The model provider does not reliably identify which curated plugin catalog is
available. ChatGPT authentication can be used with a custom provider, while an
unauthenticated session should use the API-compatible catalog regardless of its
provider.
## What changed
- Select the ChatGPT curated catalog only for authentication modes that use the
Codex backend; use the API curated catalog for API-key and unauthenticated
sessions.
- Initialize standalone plugin managers with the current authentication mode
across CLI, app-server, MCP, and external-agent migration paths.
- Preserve authentication mode while detecting and importing migrated plugins.
## Testing
- Cover catalog and skill routing across ChatGPT, API-key, unauthenticated,
Bedrock, and custom-provider configurations.
- Verify authenticated plugin migration uses the ChatGPT curated marketplace.
GitOrigin-RevId: 660a339ee8891c33aad961078d3a979242a6a166
## Why
Hooks supplied as managed requirements must not be silently skipped when their
handlers cannot be loaded.
## What changed
- Fail session and app-server thread startup when an enabled managed requirement
contains an invalid matcher, an empty command, or an unsupported handler type.
- Keep load failures for ordinary managed configuration hooks as warnings, and do
not enforce managed hook requirements while the hooks feature is disabled.
## Testing
Added hook-engine, core session, and app-server coverage for valid and invalid
managed hook requirements.
GitOrigin-RevId: 91a23b0c1d85e143aba6aabe874c5274e52fc6b2
## Why
Project-local configuration can launch host processes. Requested write access may be reduced to read-only by managed constraints or platform support, so the request alone must not cause the app server to trust a project and load its configuration.
## What changed
- Base automatic project trust on the effective permission profile after configuration is loaded.
- Trust managed profiles only when their effective filesystem policy allows writes to the working directory.
- Continue resolving trusted nested working directories to the repository root.
## Testing
- Verify that managed read-only permissions neither persist project trust nor load a project-local MCP server when workspace-write access was requested.
- Cover effective read-only fallback for workspace-write requests and nested repository working directories.
GitOrigin-RevId: e548fd9c4552c328f779cc0365fe86f37d4a9b71
## What changed
- Accept root `http://` and `https://` URLs in `--code-mode-host` and use the
shared gRPC session provider for those endpoints.
- Keep `ws://` and `wss://` URLs on the existing WebSocket transport.
- Reject paths, queries, fragments, and credentials where unsupported, without
exposing gRPC URL credentials in command-line validation errors.
## Testing
- Cover argument parsing and transport selection for both remote protocols.
- Exercise a gRPC host shared across app-server threads and verify credential
rejection does not disclose usernames or passwords.
GitOrigin-RevId: b6516a85cf76db5c4cea620f89ef866d8af30cf0
## What changed
- Resolve manifest-declared metric operations against the executor filesystem for remote plugin commands.
- Create the measurement sidecar in an executor-native, owner-private temporary directory, stream its bounded output back for validation, and clean up the directory afterward.
- Extend the exec-server protocol with the executor temporary directory and atomic private-directory creation.
## Testing
- Cover remote unified-exec measurements for foreground and background commands.
- Verify private directories use owner-only permissions on Unix and fail closed on unsupported platforms.
GitOrigin-RevId: dbbd0a84717b91237fc5728e510e18994eb46dd4
## What changed
- Extend `account/usage/read` with an optional `threadId` request and a
backward-compatible `threadUsage` response containing estimated credits,
optional USD cost, and model, reasoning, speed, and token breakdowns.
- Fetch thread usage for eligible Business and Enterprise plans when `/status`
is opened, then update the rendered status card asynchronously.
- Preserve terminal scrollback when replacing a visible status-card tail, and
append a refreshed card when the original tail can no longer be updated.
## Testing
- Add app-server coverage for authentication, canonical thread IDs,
unavailable billing routes, and malformed IDs.
- Add TUI coverage for usage formatting, stale responses, retries, history
updates, terminal reflow, and scrollback preservation.
GitOrigin-RevId: 49300914b3fba917c0f08e8595363e04e5ba6d37
## What changed
- Add end-to-end tests for curated plugin measurements through classic shell execution and unified exec.
- Cover unified background commands whose measurements arrive after the turn completes.
- Verify command attribution and measurement payloads, including values, dimensions, execution IDs, and thread, turn, and item IDs.
GitOrigin-RevId: 866103aafef8d3454123c40aee7041912ad0b7fc
## What changed
- Add `TurnInputRequest` and typed submission results for atomically starting a turn, steering the active turn, or declining input with a specific reason.
- Expose `start_or_steer_turn`, `start_turn_if_idle`, and `steer_turn` on `CodexThread`, and migrate Core consumers to these APIs.
- Make app-server `turn/start` steer an active regular turn and return that turn's ID. Reject incompatible output schemas and non-steerable turns without applying settings or enqueueing input.
## Testing
- Cover concurrent start-or-steer submissions, accepted and rejected settings updates, output-schema compatibility, idle-start rejection, and app-server steering.
GitOrigin-RevId: dd9b5528d76ec650c019e97af420bc13190ea86a
## Why
World-state snapshots and merge patches are keyed collections of sections. Allowing
their persisted `state` field to contain any JSON value required replay code to
handle shapes that cannot represent world state.
## What changed
- Type `WorldStateItem.state` and snapshot patches as JSON object maps.
- Reconstruct full snapshots directly from those maps and apply patches without
fallible arbitrary-value conversions.
- Regenerate the app-server protocol schema for the object-only representation.
GitOrigin-RevId: 3d7662b74f3dd1f3ccc5fdd0200074c13a73cbe5
## Why
Executor-backed skills can include bundled scripts, so skill readers need the
skill directory in the executor filesystem to locate them.
## What changed
- Add `skill_root` to `skills.read` responses for executor-backed skills.
- Derive the root from the parent directory of the skill's main resource and
omit the field for other skill authorities.
## Testing
- Verify executor skill reads return the expected root for both `SKILL.md` and
a referenced resource.
GitOrigin-RevId: b7035c7e2e62155890795fb508fefe3a1c17805b
## Why
Skill catalogs can present shortened package locators, but callers previously had
to expand those aliases before reading a skill.
## What changed
- Resolve catalog aliases automatically when `skills.read` looks up a
model-visible executor or orchestrator skill package.
- Update skill prompts and tool documentation to tell models to pass the listed
package locator directly.
## Testing
- Exercise reading an executor skill through its shortened package locator when
the skills catalog exceeds its context budget.
GitOrigin-RevId: d1cdfd64002510b616146929deb5b7077850b951
## What changed
- Add `http_headers_helper` configuration for local streamable HTTP MCP servers. The configured shell command runs once per connection and returns a JSON object of headers that is cached across requests.
- Apply helper headers to MCP startup and OAuth flows while restricting them to the server origin, stopping redirects, rejecting reserved or duplicate headers, and enforcing output and execution limits.
- Reject helpers for remote or managed-disabled servers, use the local environment working directory, and redact helper commands from `codex mcp list` and `codex mcp get` output.
## Testing
- Cover configuration validation, helper lifecycle and output parsing, origin isolation, OAuth discovery and token refresh, managed requirements, environment selection, and CLI redaction.
GitOrigin-RevId: 84e0e26ce75520b0869d37c72b1678e033bd6818
## What changed
- Mark developer messages received from clients with `client_authored` harness
metadata when `retain_client_developer_messages` is enabled.
- Carry that provenance through pending input and persist it alongside rollout
response items without adding it to provider requests or the serialized
`TurnInput` payload.
- Preserve existing behavior for unannotated response items and when the
feature is disabled.
## Testing
- Cover client item injection before and during turns, additional application
context, rollout replay, image resize notices, and serialization boundaries.
GitOrigin-RevId: f385c177732becde732272e4b8440eb91f5c1039
## What changed
- Parse `node_repl_auto_review_required` and `node_repl_disabled` from model catalog entries and include their values in each turn's Responses API metadata.
- Treat both fields as reserved metadata so client-provided values cannot override the selected model's policy.
- Use the selected review model's catalog entry when building metadata for review turns.
## Testing
- Cover metadata propagation across model switches, review turns, Responses API requests, and MCP tool calls.
GitOrigin-RevId: c1f63426eeb8e559abff439fbc618716a4908aff
## What changed
- Use the standard automatic test environment for plugin list, install, and
uninstall app-server tests.
- Keep the bundled stdio MCP test host-local because its fixture is a local
executable.
- Strengthen that test to verify the bundled server initializes and exposes
its `echo` tool.

## What changed
- Add an embedded `defaults.toml` and always install it as the lowest-precedence configuration layer when no packaged-defaults path is supplied.
- Keep packaged defaults out of config RPC layer and origin metadata.
- Report a user setting as overridden only when the effective layer has higher precedence, so clearing a setting can fall back to its packaged default without a false override.
## Testing
- Cover loading the packaged layer when other configuration files are absent.
- Cover config RPC filtering and clearing a user value that falls back to a packaged default.
