## Why
Allow workloads to make AWS requests with placeholder credentials while keeping real AWS credentials in the trusted proxy process.
## What changed
- Add an `aws_sigv4` hook action with a placeholder access key ID, region, service, HTTPS port, and credential sources from proxy environment variables or files.
- Re-sign matching requests after network and hook authorization and header transformations, using the configured credentials and optional session token.
- Support empty payloads and explicitly unsigned payloads, including streaming unsigned S3 uploads. Reject selected requests with incompatible credential scopes, presigned URLs, unsupported streaming signatures, or ambiguous framing through the hook denial path.
- Mark generated credential headers as sensitive and suppress signing SDK trace events that could expose credentials.
## Testing
Add tests for the published AWS IAM signature vector, unsigned S3 uploads with a session token, and rejection of invalid transport, credential scopes, signing inputs, and unsupported bodies.
GitOrigin-RevId: ab4fbbc00ba40a5bb309add521fea6ee2ff6e79e
## Why
Local administrators need to require managed configuration from a specific customer-hosted server before a session can start.
## What changed
- Add a local managed `config_server` requirement with an HTTPS base URL and optional OAuth settings. Validate endpoints and derive the bundle route as `codex/config/bundle` beneath the base URL.
- Replace the entire `config_server` block when a higher-priority requirements layer supplies one, keeping the endpoint and OAuth settings together. Reject this setting in fetched policy.
- Track the applied server through configuration snapshots, role overrides, and refreshes. Reject session startup and managed refreshes when the applied server does not match the requirement; user refreshes retain the session's managed configuration.
## Testing
Add coverage for missing, mismatched, and matching server configuration at session startup, whole-block replacement, rejection of server settings in fetched policy, and preservation across role overrides and refreshes.
GitOrigin-RevId: 51e8a1738dabdb117ae858120f6fb09ae2ff1261
## What changed
- Add `OAuthSessionRequest` to pair access tokens with their authorization identity and retain rejected-token recovery across transient failures and retries. New sign-ins receive an identity that survives token refresh.
- Expose explicit login, logout, and authorization identity lookup, plus a per-manager option to disable automatic browser login while allowing credential reuse and refresh.
- Move serializable `OAuthSessionConfig` into `codex-model-provider-info`, add an optional `device_authorization_url` field, and share endpoint URL validation through `codex-http-client`.
- Distinguish permission failures, transient token endpoint failures, and invalid responses using `io::ErrorKind`.
## Testing
Add coverage for sign-in identity preservation through refresh retries, removal of saved and cached credentials on logout, and suppression of automatic browser login. Extend token endpoint error classification coverage.
GitOrigin-RevId: ae9f72e787171e179fe139a3b840a9f7e1e46506
## What changed
Add the `codex-direct-tool-timing` crate to record tool execution, automated reviews, human waits, and dependency paths. Human waits take precedence over overlapping reviews, and dependency waits with unavailable history are recorded as unknown time.
Invocation guards complete each call once, explicitly or on drop. Separate invocation identities prevent late review or wait guards from affecting calls that reuse an ID; duplicate active IDs disable ambiguous path attribution. Batch timing exposes the last-finishing invocation's path once all calls complete.
## Testing
Add unit tests for parallel batch completion, duplicate and reused call IDs, cancellation, missing dependency history, overlapping reviews and human waits, and nested wait guards.
GitOrigin-RevId: 8b251f51a0c52342657f2d244524b562a371bd8e
## What changed
Expose `connect_windows_proxy` for callers handling a CONNECT `407` response. Use libcurl with the signed-in Windows user's Negotiate or NTLM credentials, then return the authenticated connection with buffered data preserved.
Support HTTP and HTTPS proxies, with default or caller-provided TLS configuration. HTTPS proxies requiring authentication tokens bound to their TLS connection are unsupported.
Enable libcurl's NTLM support in Cargo and Bazel builds.
## Testing
Add a Windows-only test asserting that libcurl provides NTLM, SPNEGO, and SSPI support.
GitOrigin-RevId: 4ed7d2208766404b6125ce2f4b5f91de5616a37f
## What changed
- Store `logs_2.sqlite` in `log_dir` when explicitly configured, unless a managed `sqlite_home` requirement applies. Keep other databases in `sqlite_home` and preserve the existing SQLite log location when `log_dir` is unset.
- Initialize and lock the selected log directory only when opening its database, so an unavailable directory does not prevent authentication commands from loading configuration. Share the cleanup lock across configuration clones and allow failed initialization to be retried.
- Leave existing logs in place. Read legacy logs for diagnostic submissions when the current query returns no logs, attaching them as `codex-logs-legacy.log`. Continue retention cleanup and page reclamation for both locations, with independent maintenance locks and filesystem checks.
## Testing
Add coverage for configuration routing and managed requirements, deferred initialization and lock lifetimes, authentication with an unavailable log directory, legacy log attachments, and cleanup of current and legacy databases.
GitOrigin-RevId: 48216694596d738eff1b3c5eef6c4e7ada6d0137
## What changed
Add `codex migrate-nfs-db` to replace configured SQLite WAL databases in place with validated copies in `DELETE` journal mode, retaining the originals and their sidecar files in backup directories. Stage conversion locally, check database integrity before installation, and support resuming an interrupted replacement.
Require confirmation and exclusive access, with all Codex instances stopped on every host until migration succeeds. The NFS mount must support cross-client POSIX locks. Reject unsupported file permissions and ACLs, and serialize migrations with a migration lock.
Support configuration overrides, `--profile`, and `--staging-dir`. Skip the logs database when `log_dir` is explicitly configured and leave databases already in `DELETE` mode unchanged. Reject remote mode.
GitOrigin-RevId: 7b48cc3a713113a3c09a2243e49b54258bef609d
## What changed
Move the message-board API, types, permissions, storage backends, and tool implementations into the new `codex-message-board` crate. Keep extension registration in `codex-agent-message-board-extension`, and update core and the remote client to use the shared crate directly.
Move the existing board tests with the implementation and add the crate to the Cargo workspace and Bazel build.
GitOrigin-RevId: 33ce527c2bef7f862eba55cb9b32222902ccf4ad
## What changed
Add a save RPC that accepts the existing report options and an absolute `savePath` on the server host. Save the report, selected attachments, and a manifest without uploading, and return `savedPath`, `threadId`, and `promptHash`. Local exports remain available when uploads are disabled by configuration.
Publish archives atomically without replacing existing files. Bound uncompressed contents to 200 MiB and attachments to 128, preserve duplicate attachment names safely, and fail without publishing a partial ZIP when a selected file cannot be read. Honor `includeLogs` and omit automatic rollouts for untouched threads without materializing them.
Update protocol schemas and generated TypeScript and Python types.
## Testing
Add coverage for local-only saves, disabled uploads, path validation, overwrite protection, log consent, archive budgets, duplicate names, missing files, and rollout selection before materialization and after writer shutdown.
GitOrigin-RevId: 222c0fe7ab923904de9c8a9f12ad27f7a0104875
## Why
Managed stderr logs previously retained a tail only before a new launch, allowing logs to grow during a long-running process. Direct stderr writes could also block lifecycle operations on disk I/O.
## What changed
- Route managed app-server and updater logs through a shared nonblocking worker with a bounded queue. Drop records when the queue is full or a record exceeds 16 KiB, and avoid waiting for the worker at shutdown.
- Prune live logs when they exceed 1 MiB, preserving the latest 256 KiB in `.log.previous` before truncating the current file. Keep inherited stderr handles usable after truncation.
- Pause predecessor pruning during Windows updater handoff and resume it after a failed handoff only when ownership has been restored.
- Keep ordinary stderr output when managed logging has not been initialized.
## Testing
Add regression tests for stalled workers and queue overflow, tail retention, inherited append and nonappend handles, and pruning exclusion during updater handoff.
GitOrigin-RevId: b6301962b1180fa6cdb231a56edce2429dc20b54
## What changed
Add `codex-utils-critical-path` to track shared dependency paths and attribute time to inference, automatic review, user waits, tools, overhead, and unknown work. Parallel joins retain the later-finishing branch, preserving its full history without double-counting overlapping work.
Clip attribution to the requested interval and count unrecorded gaps as overhead. Bound retained history by collapsing it into unknown work at the depth limit, with nonrecursive destruction and bounded debug output.
## Testing
Add unit tests for parallel joins, nested dependencies, ties, user waits, interval clipping, overlapping segments, history exhaustion, and safe formatting and concurrent release on small stacks.
GitOrigin-RevId: 2df7453162491d3ae97bf4bee942730c8a4d5e5c
## What changed
- Update Cargo and Bazel toolchain pins, CI and release workflows, and Windows setup from Rust `1.95.0` to `1.99.1`.
- Adapt Rust code to updated APIs and lint requirements, including `try_update` and `as_chunks`, and refresh the halfwidth sound marks snapshot.
- Update `webpki-root-certs` from `1.0.5` to `1.0.10` in the Cargo and Bazel lockfiles.
GitOrigin-RevId: e1aaed63b7e72bb8c8bbe25b32c6329c9a37b6c3
## What changed
Collect compressed rollout paths and scan them in up to four concurrent batches, reusing compiled search patterns within each batch. Preserve match snippets, plain rollout path keys, and per-file error handling.
## Testing
Extend the regression test to verify matches across seven compressed rollouts while skipping a corrupt file, and retain coverage for oversized search patterns and missing files.
GitOrigin-RevId: 522403654ab8577499f8f8043ccc017590c4833e
## What changed
Add `RuntimeAuthProvider` to resolve request authentication through the runtime auth manager. Support `dual_header` mode, which sends a bearer credential alongside `x-openai-agent-assertion`, and `assertion_only` mode, which uses `Authorization: AgentAssertion …`.
Replace stale authentication headers and sign a fresh assertion for each request attempt. Propagate registration failures without falling back to credential-only authentication, preserving policy errors and classifying transport failures, rate limits, and server errors as transient.
Add the disabled-by-default `features.runtime_agent_instances` configuration with independent `enabled` and `mode` settings, schema support, and structured override merging. Selecting a mode alone does not enable the feature.
## Testing
Add coverage for both modes with API key and ChatGPT credentials, stale header replacement, fresh assertions, credential refresh without runtime replacement, registration failures, and configuration parsing and merging.
GitOrigin-RevId: 9e93d25762600f0ff592c5248fe4c8c2c8182c8d
## What changed
- Update `rustls-webpki` from `0.103.15` to `0.103.16`.
- Update `webpki-roots` from `1.0.5` to `1.0.10`.
- Refresh the corresponding entries in `codex-rs/Cargo.lock` and `MODULE.bazel.lock`.
GitOrigin-RevId: c73d2afb6ce9f8bd8756d3cbe6f8114edc461262
## What changed
Read `RequirementsPath` from the 64-bit registry view of `HKLM\SOFTWARE\Policies\OpenAI\Codex` to select the system requirements file on Windows. Require an absolute path and return an error for relative values. If the registry key or value cannot be read, retain the default `OpenAI\Codex\requirements.toml` location under ProgramData.
## Testing
Expand absolute-path validation tests to cover empty, drive-relative, and root-relative paths. Update the Windows default-directory test to remain independent of registry overrides.
GitOrigin-RevId: c31045d749e32cf266b389245ae4db2440156e8e
## What changed
Add `RuntimeAuthManager` to share one registered runtime per credential source and return request-scoped `RuntimeAuth` values that pair the runtime with its credentials and HTTP client factory.
- Preserve registration keys and idempotency IDs across retryable failures and refreshes that retain the credential source.
- Replace the runtime when the credential source changes, preserve existing request snapshots, and reject late registration responses for a previous source.
- Use bounded credential recovery for registration `401` responses and cache `403` denials until the credential source changes.
- Expose authenticated actor and agent host information on `RuntimeAgentInstance`.
## Testing
Add tests for concurrent registration sharing, retry identity preservation, network policy recovery, credential refresh and replacement, bounded recovery, cached denials, and credential changes during registration.
GitOrigin-RevId: ea1e6e10a5939e8c3f7c0c317ccf8a83522c635f
## What changed
Extend `codex-runtime-agent-instance` with a registration client and an in-memory assertion signer. Pending registrations retain their signing key and idempotency key across caller-driven retries; registered runtimes generate fresh versioned assertions with a timestamp and unique ID.
Bound registration requests and responses, reject unsafe endpoints, disable redirects and request logging, and preserve network policy errors. Report server rejections using only the status and recognized error codes.
## Testing
Add HTTP-backed tests for retry stability, assertion signatures and freshness, policy revocation, endpoint and response validation, redirect refusal, and error redaction.
GitOrigin-RevId: a6dab0900459dfb75f72652a0a2ee1e4b65ca322
## What changed
Add `codex-runtime-agent-instance` with serializable registration requests and deserializable responses. Requests support OAuth, personal access tokens, and platform API keys, along with an installation ID, public key, harness metadata, and runtime role. Responses include runtime and host IDs plus ChatGPT or platform actor context.
Use `RedactedString` for credentials to keep secrets out of debug output.
## Testing
Add tests covering request serialization for all three credential types, debug redaction, response decoding for both actor types, and rejection of responses missing required fields.
GitOrigin-RevId: f33bae734fdd1402144dee407e5b868f5eef1d37
## What changed
- Replace the separate MXC crates with `mxc-sdk` and adapt request construction to its policy and optional environment fields.
- Preserve the native availability probe by caching successful process security environment creation and startup attribute initialization without launching a process.
- Use the SDK's native denied-path support check and configure Bazel resource compilation for Windows GNU targets.
## Testing
Extend the request construction test to verify that nonempty environments use `Some` and empty environments use `None`.
GitOrigin-RevId: 2765c8fd19ee60661b0ce7cb3cba51acadda201a
## What changed
Add `thread/sample` to collect one model response on an ephemeral fork that inherits a loaded thread's context and configuration. Return the source turn ID, response ID, assistant text, and available token usage without modifying the source conversation.
Require an idle, persistent root thread and an `expectedTurnId` matching its latest completed turn. Reject results if the source history changes during sampling. Keep the parent responsive while sampling, hide sample forks from `thread/loaded/list`, and reclaim them after completion or timeout.
Intercept responses before tool execution or Stop hooks can run, returning null text for tool calls or responses without text. Apply optional reasoning-effort updates only when the provider and model support cache-preserving updates.
## Testing
Add integration coverage for inherited context and reasoning effort, source preservation, tool and Stop hook suppression, invalid requests, stream errors, parent responsiveness, and timeout cleanup.
GitOrigin-RevId: 08f4867e53ec7f6c8f4428d5542eeea4e6dadd0b
## What changed
- Build executor skill catalogs from discovery V2 inventories without reopening host paths or falling back to legacy discovery.
- Merge Cloud and executor skills by remote plugin identity and skill name, retaining Cloud metadata and accepted provider read routes. Apply plugin selection and disablement before merging.
- Share a stable catalog across each step's rendering, list/read tools, and explicit and implicit skill invocations.
- Preserve unmatched executor entries when Cloud catalogs are unavailable or partial; only complete Cloud catalogs disable unmatched remote entries.
- Bind discovery caches to captured environments and executor sessions, and refresh MCP when V2 inventories change. Preserve pending invalidations when forced MCP refreshes fail.
## Testing
Add regression coverage for V2 inventory sharing and refresh, environment isolation, catalog merging, partial Cloud results, disabled plugins, and catalog consistency across steps and read routes.
GitOrigin-RevId: 842bdcbc9e19364dd69a9abf9e48330b7425a76c
## What changed
- Use V2 discovery inventories for plugin MCP contributions when supplied, including empty or failed inventories; retain legacy discovery when no V2 snapshot is supplied.
- Merge plugins by canonical identity, using cloud metadata and enablement for remote plugins and attaching executor installations only when versions match. Preserve configured executor-local plugins and executor enablement when cloud data is unavailable.
- Keep installation order stable across refreshes and run merged MCP declarations on the first retained executor installation while preserving attribution for the others.
- Carry local and remote identities through selected-plugin snapshots, skill attribution, and active-plugin telemetry. Track disabled plugin IDs alongside disabled roots.
- Preserve a complete cloud catalog when a partial refresh arrives, and cap tool-description plugin attribution at 1,024 bytes while retaining all plugin associations.
## Testing
Add coverage for catalog parsing and reconciliation, enablement and discovery-mode selection, installation refresh ordering, executor-specific MCP normalization, selected-plugin snapshots, and bounded UTF-8 attribution text.
GitOrigin-RevId: a8ad352de6a2b8dc4bfd1ff6a5c62ee8ed1d1664
## What changed
Add a federated `Auth` variant that exchanges JWT subject tokens for OpenAI access tokens using identity provider and service account IDs. Serialize concurrent exchanges, cache credentials, and renew proactively with a fresh subject token.
Validate token types, bearer credentials, payload sizes, and lifetimes. Bound caching by both relative and absolute expiry, discard cached credentials before renewal, and disable redirects for federated requests. Keep credential buffers zeroizing and diagnostics free of secrets.
## Testing
Add HTTP fixture tests for concurrent cache reuse, renewal with fresh subjects, expiry across host suspension, failed renewal, oversized payloads, invalid subjects, and unsupported or missing issued token types.
GitOrigin-RevId: e7e6dacd4a834fb73166caf146d4cdc50a895f56
## What changed
Add a `GithubOidc` implementation of `SubjectTokenSource` that requests a fresh token using a bearer credential read from stdin. Validate HTTPS request URLs and replace the audience query parameter while preserving other parameters. CLI integration is not included.
Add a token HTTP client that disables redirects and request logging, applies timeouts, and bounds response bodies. Keep token response buffers in zeroizing storage and exclude credentials, request URLs, and response bodies from errors.
Generalize the locked stdin credential reader for bounded OIDC bearer tokens while preserving API key validation.
## Testing
Add tests for fresh token acquisition, short reads, credential size limits, injection rejection, redirect refusal, and credential-safe errors and logs. Extend API key tests to retain the stricter character restrictions.
GitOrigin-RevId: fd7767178f475b8161734f29d29108c795839185
## Why
Configuration loading can finish before a pending startup is visible to the thread manager. Reloads need a cancellation scope that also covers these configuration snapshots.
## What changed
- Capture an enterprise managed authentication (EMA) cancellation token before loading configuration and carry it through config layers, role overrides, runtime refreshes, and `McpConfig`.
- Cancel the previous scope on MCP or user configuration reloads and cloud config loader changes, then create a fresh scope for subsequent loads.
- Cancel the session's token when enterprise MCP authentication is disabled or a refresh leaves it unavailable.
## Testing
Extend the MCP reload test to verify that existing thread and pending startup tokens are cancelled while a fresh startup receives an uncancelled token.
GitOrigin-RevId: 5fc0658b74c360e7dc9ab3488339fcf19bfe9fae
## Why
Replacing rollout files can lose Unix ownership or macOS ACLs, changing who can read or append to a transcript. An ACL can also permit appending while denying explicit timestamp updates.
## What changed
- Preserve Unix ownership, permissions, modification times, and macOS ACLs before publishing compressed or restored rollouts, and verify the replacement can be reopened.
- Abort replacement on metadata failures, reject macOS delete-deny ACLs to keep temporary files removable, and detect Unix access metadata changes through `ctime` checks.
- Use managed restoration temporary files whose names avoid stale `*.tmp` cleanup.
- Allow appending when refreshing the rollout's modification time returns `PermissionDenied`.
## Testing
Add regression coverage for macOS ACL preservation, inherited ACL removal, deletion-protected rollouts, append access despite denied timestamp changes, Unix group preservation, and restoration temporary files surviving stale-file cleanup.
GitOrigin-RevId: 23f3de6e35c0b2e19f3491170e320159ea3bdb6f
## What changed
- Negotiate compression over TCP and local sockets with `x-codex-app-server-compression: zstd-stream-v1`. Keep JSON text messages when compression is not negotiated.
- Send compressed JSON as binary messages, retaining a separate zstd stream per direction across messages. Export reusable negotiation and codec helpers.
- Limit decompressed messages to 64 MiB and compression windows to 1 MiB. Close compressed connections on decoding errors or unexpected text messages.
- Add audit and deny ignores for the unmaintained `zvariant`, `zbus_names`, and `zvariant_derive` versions pulled in through `zbus`.
## Testing
Add codec tests for retained history, fallback, size limits, malformed data, and oversized compression windows. Add TCP and local-socket round-trip tests covering negotiation, persistent streams, and ping/pong handling, plus TCP fallback for absent or unsupported offers.
GitOrigin-RevId: 50d3861e8fe4a9c523599a5ab773bec7cb883bf2
## Why
Contextual fragments and extension-owned world-state sections currently return strings, limiting them to text content.
## What changed
- Return `ContentItem` from fragment bodies and rendering, preserving classification and attribution. Apply text markers only to `InputText`; pass other content through unchanged.
- Allow extension prompt and world-state contributions to carry typed content, and preserve media in context-window hints.
- Hash non-text world-state fragments by their serialized content and role while retaining the existing text hashing behavior.
- Add shared content-to-tool-output conversion that preserves image references, image detail, and audio.
## Testing
Add coverage for typed world-state hashing and preservation of image content and attribution. Expand code-mode output tests to cover input text, output text, file-backed and inline images, and audio.
GitOrigin-RevId: 2ed00d466a3f169b151202f3eef71e667ea64be1
## Why
Curated plugin archives should preserve executable permissions without applying setuid, setgid, or sticky bits.
## What changed
- Upgrade `zip` from 2.4.2 to 9.0.0, retaining the previous feature set and selecting the existing `bzip2-sys` backend explicitly. Update the Cargo and Bazel lockfiles.
- Adapt plugin extraction to fallible entry names and apply Unix permissions through the open output file, using the mode filtered by `zip`.
## Testing
Add a Unix regression test that encodes special permission bits directly in an archive entry and verifies that the extracted file has mode `0o755`.
GitOrigin-RevId: 75ee6879a372a36b34208c1359f42b670c9d3837
## What changed
Add the `multi_env_copy_file` feature flag, disabled by default and marked as under development, to the feature registry and configuration schema. Install the file-copy extension in app-server threads and CLI debug prompt construction when the flag is enabled.
GitOrigin-RevId: 6d8b4c7479974f4b70c39f52333491c13d60d2a2
## What changed
Read `desktop.uninstall_codex_home` from the owner's current `config.toml` before recursively deleting a desktop-created Codex home during Windows sandbox uninstall.
- Preserve the home by default for ordinary installations; retain the deletion default for OEM preinstalls when no preference is set.
- Let an explicit boolean preference override either default. Preserve the home when configuration is unreadable, malformed, or contains an invalid preference.
- Capture OEM metadata before Windows removes it during uninstall, and revoke sandbox permissions on retained homes.
## Testing
Add unit tests for missing preferences, explicit overrides, malformed or invalid configuration, and configuration read failures across both installation defaults.
GitOrigin-RevId: 46afc2a7b0f4ecf7f447e46b515e50d0d278e4a8
## What changed
Add the `codex-multi-env-copy-file` extension, exposing `multi_env_copy_file` when registered by the host. Copy files between distinct selected environments without loading their contents into model context, and return `bytes_copied` on completion.
Require absolute paths in each environment's native path convention and enforce each endpoint's sandbox policy and permission grants. Stream file contents where supported, with a buffered fallback for older executors. Reject same-environment copies and report I/O error kinds without exposing connection details. Warn that failed writes may leave a truncated or partially written target.
## Testing
Add integration tests for binary transfers in both directions, local and remote executors, path validation, opt-in tool visibility, endpoint permissions and grants, and unavailable or disconnected executors. Verify that copied contents stay outside model context.
GitOrigin-RevId: f5d9e423d105019834e0288828cb68c5711b3a49
## Why
Authorization server metadata can advertise scopes unrelated to the MCP resource. Using that list for discovery can request broader scopes than the resource requires.
## What changed
Update `rmcp` and use its initial scope selection during OAuth discovery: prefer scopes from the initial `WWW-Authenticate` challenge, fall back to protected resource metadata, and include `offline_access` when supported. Stop using the authorization server's general scope list as the discovered resource scopes.
## Testing
Add coverage for challenge scope precedence, resource metadata fallback, scope normalization, and exclusion of unrelated authorization server scopes. Add a no-browser login regression test for a preregistered client whose authorization server advertises neither scopes nor dynamic registration.
GitOrigin-RevId: 68d83cf61fb0b73dac9e861e476f484990fd93b6
## Why
A plugin's scripts can change without changing its hook declaration. Declaration-only approval therefore lets changed plugin code run under an existing hook approval.
## What changed
- Fingerprint plugin bundle contents and include the content hash in the approval value returned by `hooks/list`. Persist it as `trusted_content_hash`, keeping `trusted_hash` compatible with older clients.
- Verify contents before each command or MCP hook execution, within the hook's timeout, and require renewed approval when approved contents change.
- Migrate legacy declaration-only approvals to a shared, immutable content baseline per plugin and config home.
- Exclude generated Python bytecode, `.venv`, and `.egg-info` entries from fingerprints. Run app-server hook listing on blocking tasks.
## Testing
Extend integration coverage for plugin upgrades and rollbacks requiring approval, same-turn script changes preventing further hook execution, shared legacy approval baselines, and generated Python artifacts preserving trust.
GitOrigin-RevId: faaf7658210d8adb2534ddd614c72ec993920840
## Why
Optimized `Array.prototype.sort` can write objects into incompatible array element storage when receiver element kinds differ and the comparator mutates the array.
## What changed
- Upgrade `v8` to `152.2.0`, the Bazel V8 source to `15.2.124.1`, and ICU data and initialization to version 78.
- Backport element-kind agreement checks for sort inlining in TurboFan and Maglev. Apply the patch to Bazel builds and Windows MSVC source builds, and include it in source-build cache keys and canary triggers.
- Refresh pinned sandbox archives and bindings, extend Bazel prebuilt coverage to musl Linux, and use matching sandbox bindings on Windows MSVC.
- Update Bazel integration patches and runtime dependencies for the new V8 release, and download the pinned Windows build tools in source-build workflows.
## Testing
Include the upstream sort regression test covering mixed element kinds, comparator mutation, and continued optimization for matching kinds. Add a test requiring canary and Windows source builds when the backport changes, and update artifact-fetch tests for the new version.
GitOrigin-RevId: 138b7821cddd25466c10aced1dd22be24837caf0
## What changed
Add optional `inputImages` metadata containing each referenced local image's path and SHA-256 hash of the bytes read before normalization. Compute the hash from the same bytes used to prepare the edit request.
Preserve this metadata through completion events, persisted thread history, resume, and legacy rollout migration. Update app-server schemas and generated TypeScript and Python types; older items continue to deserialize without the field.
## Testing
Add coverage for input ordering, changed contents at the same path, unreadable or invalid references, serialization, persisted history and resume, and legacy migration.
GitOrigin-RevId: 522be8ec1e39c9b2bbe5b9ccb37ea67d17f0e21a
## Why
SQLite page reclamation on NFS creates I/O load and contention.
## What changed
Detect whether `sqlite_home` is on NFS on Linux and skip reclamation before opening a maintenance connection. Cache successful filesystem probes across `SqliteConfig` clones while allowing failed probes to retry.
## Testing
Add tests for shared probe caching and recovery after a missing directory is created. Update reclamation coverage to expect no reclaimed pages or file shrinkage on NFS.
GitOrigin-RevId: 4f627cabc6ad712171654c3f8b8659d2f632bbba
## What changed
- Launch managed processes through `taskpolicy -b` on macOS when a five-second probe succeeds, preserving the managed process PID. Fall back to direct launch if the probe fails or times out.
- Increase the macOS startup timeout from 10 to 30 seconds to accommodate background CPU and I/O scheduling, and serialize daemon startup test fixtures on macOS.
- Use the shared background command helper and retain `CREATE_NO_WINDOW` alongside Windows detachment flags.
## Testing
Add macOS tests for PID preservation, background priority when available, and direct-launch fallback after a probe timeout.
GitOrigin-RevId: ab3328e2e8f62218ac9602e4172563c00056875b
## What changed
- Upload generated images to the attachment store and expose `fileId` in image-generation items when available, with inline `result` fallback on upload or decoding failure.
- Preserve file references through legacy events, persisted rollouts, thread history, and task output summaries. Keep model-facing image preparation separate.
- Add attachment request tags and mark generated-image uploads with `usage=image_gen`, preserving the thread's ephemeral setting.
- Update public schemas and SDK types to accept either image representation, retain the Python `ImageGenerationThreadItem` alias, and prefer `fileId` when reading records containing both fields.
## Testing
Add coverage for file-backed generation and rollout persistence, legacy history replay, inline and transitional serialization, task output visibility, and Python SDK alias compatibility.
GitOrigin-RevId: f7a2bb5707e2f277348a547a988bc33c8e96d891
## Why
On case-insensitive macOS filesystems, paths such as `.GIT/config` refer to protected `.git/config` metadata but can pass case-sensitive write permission checks.
## What changed
Check native filesystem case sensitivity when matching protected metadata paths, including case aliases in workspace roots. Recheck both the target and policy entries with normalized aliases so explicit metadata grants and narrower restrictions retain their precedence. Return errors when filesystem case sensitivity cannot be established.
## Testing
Add macOS coverage for metadata and workspace-root case aliases, explicit grants, narrower restrictions, and missing directories. Strengthen the patch regression test to assert the approval rejection message for both direct `apply_patch` calls and shell interception.

## Why
Keychain signing reconstructs its own authentication context, so invalidating the caller's context does not reliably cancel the context that owns the biometric prompt.
## What changed
Evaluate the stored key's access-control policy explicitly with `LAContext` before signing. On cancellation, invalidate that context and wait for its authorization callback before releasing the lifecycle lock, rejecting any late success. Reload the key with the authorized context and disable further interaction so signing cannot open another prompt.
## Testing
Update unit tests to cover waiting for cancellation completion and rejecting completed authorization after cancellation. Add an ignored macOS hardware test and setup instructions covering persisted Secure Enclave key reuse, signature verification, cancellation, retry signing, and cleanup.

## What changed
- Return qualified skill names such as `team:deploy` and parsed `dependencies` and `policy` instead of a separate namespace and raw metadata file. Share `agents/openai.yaml` parsing and validation between skill loaders and executor discovery.
- Include each standalone skill's search-root ID and path in `discoveryRoot`, while accepting responses from older executors that omit it.
- Add plugin `displayName`, falling back to the manifest name or installation directory.
- Materialize inline MCP declarations in `mcpConfig` with the manifest as their source path, and report incomplete discovery when declared MCP or Apps configuration files have no returned contents.
## Testing
Add coverage for JSON round trips, omitted `discoveryRoot`, optional and invalid skill metadata, qualified names, display-name fallbacks, and inline MCP configuration. Verify standalone search roots survive cached discovery and sandboxed RPC responses.

## Why
`codex app-server daemon restart` previously reused saved settings without applying feature flags supplied on the command line.
## What changed
Apply `--enable`, `--disable`, and boolean `-c features.*` overrides during an explicit restart and persist them for subsequent restarts. Accept nested `enabled` values, normalize feature aliases, and replace conflicting saved aliases while preserving unrelated settings.
Reject invalid feature toggles before stopping the daemon or saving settings.
## Testing
Add integration coverage for overrides on stopped and running daemons, alias replacement, preservation of saved settings, restarts without flags, and rejection of non-toggle keys without interrupting the running daemon.

## Why
Rewriting source agent names and instruction filenames inside URLs and email addresses can change their destinations when importing external agent content.
## What changed
Use `linkify` to preserve recognized URLs and email addresses while rewriting surrounding text, including Markdown link labels and titles. Continue migrating instruction filename references to `AGENTS.md`, including relative links and references with line or column suffixes.
## Testing
Add rewrite coverage for URLs, email addresses, Markdown links, and surrounding Unicode text. Extend skill import and app-server configuration import tests to verify that link labels migrate while URL destinations remain unchanged.

## What changed
Update `codex-rs/Cargo.lock` and `MODULE.bazel.lock` for `quinn-proto` 0.11.18, replacing 0.11.15. Refresh its resolved dependencies to use `rand` 0.10.1 and `getrandom` 0.4.2, and add `rand_pcg` 0.10.2.

## Why
Repeated turn diff notifications can print the same file changes multiple times, including after an unrelated command.
## What changed
Track the last diff and print nonempty updates only when they differ from the previous notification. Remember empty updates so a restored diff prints again, and reset the tracked diff when a new turn starts.
## Testing
Add a stderr snapshot test covering repeated, changed, empty, restored, and new-turn diffs. Add an integration test that applies one edit, runs an unrelated command, and verifies that the diff appears exactly once.

## What changed
- Update the pinned `rmcp` dependency and Cargo/Bazel lockfiles, and migrate MCP handlers and fixtures to `ClientConfig` and `ServerConfig`.
- Stop requiring responses for cancelled elicitation requests in cancellation tests while retaining checks for cleanup and continued connection usability.
- Handle client disconnects during WebSocket writes in the TUI test server, use an asynchronous HTTP mock for loopback proxy testing, and improve remote executor test diagnostics and the Windows subprocess fixture.
- Use `invalid_prompt` for the memory worker failure fixture.
## Testing
Add a regression test covering transport EOF during both form elicitation and user verification. Keep the client alive while checking that pending response channels close, the timeout pause clears, and the service exits with `QuitReason::Closed`.
