## Why
Enterprise-managed MCP authentication previously required public OAuth clients at both the identity provider and the MCP authorization server, preventing use of registrations that require client secrets.
## What changed
- Accept separate `client_secret` and `token_endpoint_auth_method` settings for the enterprise IdP and MCP server OAuth registration. Support `client_secret_basic` and `client_secret_post`, defaulting to Basic when a secret is configured.
- Validate the registered method against server metadata and use it for enterprise login and both ID-JAG exchanges.
- Require a configured `oauth.authorization_server_issuer` for confidential MCP registrations and reject empty secrets or authentication methods without secrets.
- Require the account OAuth client to match the configured IdP client before reusing an account grant with a provisioned secret; otherwise use dedicated enterprise login.
## Testing
Extend configuration, login, exchange, and app-server lifecycle tests to cover confidential registrations, separate IdP and resource credentials, authentication method validation, and exclusion of client secrets from authorization URLs, stored login grants, and logs.

## Why
HTTPS requests and WebSocket connections on Windows need to authenticate when a proxy rejects `CONNECT` with status `407`.
## What changed
- Retry proxy challenges through the existing Windows authentication helper, using the signed-in user's Negotiate or NTLM credentials. Treat an origin `407` as a normal HTTP response.
- Bridge authenticated tunnels to the HTTP client through destination-specific named pipes, retaining redirect checks and TLS backend fallback without caching those tunnels across destinations.
- Carry explicit CA certificates and client identities into HTTPS proxy TLS configuration, and apply the configured connect timeout when opening authenticated HTTP tunnels.
GitOrigin-RevId: ec7d9168972a7a640350e5348cfca40307390fbf
## 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
## Why
Callbacks from the shared stdio host need to retain each execution's trace context after it yields, without keeping the execution span open until its background cell closes.
## What changed
Capture a W3C trace-context snapshot for each execution and restore it as the parent of tool callback and notification spans. Instrument delegate invocation and its returned future so the context is available on entry and across awaits.
## Testing
Add an integration test with overlapping yielded cells completed in reverse order. Cover sampled, unsampled, and untraced callers, trace isolation, callback and notification parentage, and execution spans finishing while callbacks remain blocked.
GitOrigin-RevId: 57924123d2c2f31bcfaf725688d8bba775235fa0
## Why
Responses Lite includes retained reasoning in its reported token usage even without an `X-Reasoning-Included` header. Adding a separate reasoning estimate can trigger automatic compaction prematurely. Locally recomputed usage also already includes retained reasoning.
## What changed
Initialize reasoning accounting from `use_responses_lite` before each sampling or compaction request, while allowing server events to override it. Mark locally recomputed token usage as including reasoning.
## Testing
Update the compaction regression test to verify that Responses Lite usage without the header stays below an 81-token limit at 80 tokens and triggers compaction at 81 tokens.
GitOrigin-RevId: 06f9272cb3c259e927941f1d2a1d7096310ffb2c
## Why
Remote registry requests need to recover when credentials are rejected or rotated while `exec-server` is running. Concurrent requests should reuse refreshed credentials rather than refresh the replacement token again.
## What changed
- Add an `AuthProvider` recovery hook and retry registry registration, connection, and harness-key validation once after a `401` when the provider supplies replacement credentials.
- Use live ChatGPT authentication for remote `exec-server` and guard proactive and unauthorized refreshes so concurrent callers share the completed refresh.
- Allow executor credentials to retry when the parent has already supplied a valid replacement.
- Keep connection authentication, refresh, and retry within the original connection deadline.
## Testing
Add coverage for concurrent refreshes, stored and parent-supplied credential rotation, refresh failures, retry limits, and connection deadlines, plus a CLI integration test for refresh and credential reload in a running executor.
GitOrigin-RevId: 9ed533e410762c7ac8b7c0c30bb93fd20d96778b
## 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
## Why
`message_board_tools` always exposed all nine discussion tools. Consumers need a way to expose a subset, such as `read_thread` and `list_threads`, over the same board.
## What changed
Accept an ordered slice of the new `MessageBoardTool` enum and optional description overrides in `message_board_tools`. Use the enum for schemas and dispatch, and keep the agent extension's existing tool set and order through `MessageBoardTool::DISCUSSION`.
## Testing
Extend the local-board integration test to verify that a reader-only selection exposes exactly the requested tools in the supplied order and reads the existing discussion.
GitOrigin-RevId: 60026d73768330ff4b694c3a9e99480e3ed7af27
## Why
Local message boards use a fixed database filename. Callers need separate storage for boards that share a session identity.
## What changed
- Add `LocalBoardOptions` with a validated `storage_namespace`, and support it when opening, configuring, and permanently deleting boards.
- Allow `LocalBoard::with_options` to select storage for its connections.
- Store custom namespaces in `message_board_<namespace>_1.sqlite`, while preserving `agent_message_board_1.sqlite` for the default namespace.
- Have the agent message board extension select the same namespace for opening, setup, and deletion.
## Testing
Add coverage for namespace isolation, reopening saved posts, and avoiding collisions with other runtime databases. Update setup tests to exercise a custom namespace through reopening and deletion.
GitOrigin-RevId: a6ea8d171809625edeedc3a8ac3ee2e1bbf1682a
## 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
## Why
Mailbox preemption can discard completed response items and lose the response ID needed for incremental continuation. Buffered tool calls must also wait for queued agent messages to be read.
## What changed
- Gracefully interrupt and drain Responses Lite streams, retaining completed items and the response ID for the next request.
- Cancel buffered tool calls before dispatch and suppress partial items that may be discarded during the drain.
- Keep user steering queued until draining finishes. Include pending mail in follow-up requests after disconnects and preserve content-filter recovery guidance.
## Testing
Add WebSocket regression coverage for buffered completion, interrupts without acknowledgement, buffered tools and partial items, user steering during draining, disconnects, and content-filter recovery.
GitOrigin-RevId: c9d3fb87a81850e5686e07f28103e2ff4378ddec
## Why
Failed cloud discovery previously retried before each model step. Apply a cooldown across steps and turns to avoid repeated discovery requests while a provider remains unavailable.
## What changed
- Share per-thread retry backoff logic between cloud skill and plugin catalogs, starting at 30 seconds and doubling to a maximum of 5 minutes.
- Scope cooldowns to authentication and MCP resource generations so account changes and reconnects permit immediate recovery.
- Clear backoff after successful discovery or configuration resets, while allowing cancelled refreshes to retry immediately.
## Testing
Update lifecycle and concurrency tests to cover shared cooldowns, reconnect recovery, and cancellation. Use paused time to verify exponential delays, the 5-minute cap, and backoff across turns.
GitOrigin-RevId: 30dab5ceba51e8ad64c0794c1729719e99f577ce
## What changed
- Add `application.storage.default_project_parent` and `application.storage.projectless_workspace_root` requirements for new Desktop workspaces. Require absolute paths and reject unknown storage keys.
- Apply managed paths to `desktop.defaultProjectParent` and `desktop.projectlessWorkspaceRoot`, overriding local preferences and rejecting writes to managed settings or their containing table while preserving unrelated Desktop settings.
- Expose storage requirements through `config/requirements/read` and update generated JSON schemas, TypeScript types, and Python models.
## Testing
Add coverage for storage validation, per-setting layer precedence, config overrides, write protection, and requirements API responses. Adjust daemon shutdown test deadlines and TUI test synchronization, paste handling, and future allocation.
GitOrigin-RevId: 44b93fe69e6a471c3f485cbf5f9c9ebd34ac3234
## Why
A failed provider catalog refresh could discard model metadata and disable tool search on subsequent turns, even after a successful discovery.
## What changed
Keep the last successful catalog, ETag, and original freshness when refreshes fail without an access rejection. Continue invalidating cached catalogs for HTTP `401`/`403`, rejected refresh tokens, and gateway credentials that require login. Distinguish `GatewayLoginRequired` from login in progress so only the former invalidates the catalog.
Successful empty responses remain authoritative, and cached catalogs remain scoped to the provider and authentication identity.
## Testing
Add regression coverage for catalog preservation across refresh errors and restarts, access rejection invalidation, identity isolation, and tool search and instruction stability on the next turn after a failed refresh.
GitOrigin-RevId: 9dd7c73ac2cc1fd49664efd93b839baa94e05c49
## Why
Authentication can change between model steps. Refresh cloud catalogs before the next step so plugin acceptance and skill instructions reflect the current auth scope, including plugins that are no longer available.
## What changed
- Add a `refresh_catalog_for_step` lifecycle hook and rebuild MCP when plugin catalogs change.
- Reuse successful discovery within a turn and auth scope, serialize concurrent refreshes, and allow retries after failures or cancellation. Limit cloud skill discovery warnings to once per turn.
- Skip cloud discovery during prewarm and other context-only captures, and check hosted plugins even when no executor roots are selected.
## Testing
Add regression coverage for mid-turn auth rotation and plugin removal, serialized refreshes and retries, stale discovery results, and prewarm boundaries.
GitOrigin-RevId: 355681e84dc765e8dc1a04608779d95c706c2188
## What changed
Represent collected fragments with `RetainedInstructionItem`, preserving their content, semantic kind, and source. Assign retention policy when composing context: user instructions, host notices, and framing remain required, while assistant context remains optional at commentary priority.
GitOrigin-RevId: 0080f3abd0d763bd402e78da0ac1b0fa0cd7678d
## Why
Installed-plugin inventory fetches could keep following pagination cursors
without an overall bound, delaying release of the plugin mutation gate.
## What changed
- Limit each inventory fetch to 60 seconds and 100 pages, and reject repeated
pagination cursors.
- Request 200 items per page for scoped inventory fetches as well as all-scope
fetches.
- Report overall fetch timeouts as `remote_catalog_timeout`.
## Testing
Add coverage for cursor cycles, completion at the page limit, and overall
timeout cancellation after successful pages. Verify that failed pagination
preserves the cached inventory and plugin files and releases the mutation gate.
GitOrigin-RevId: e8429dd804581041d102defa9d19db02bcb1739b
## 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
Resuming a thread can replace saved model settings with global defaults. A selected service tier can also be lost when the current model does not support it.
## What changed
- Restore saved service tier, reasoning summary, and personality on resume unless the caller explicitly overrides them, respecting thread ownership of settings snapshots.
- Retain the selected service tier for persistence, settings notifications, and resume comparisons while filtering the effective tier against the current model's capabilities.
- Carry the runtime model, service tier, and personality into thread revert reconstruction.
- Persist initial thread settings before user input during MCP startup so an interrupted first turn retains its settings checkpoint.
## Testing
Extend regression coverage for cold resume and explicit overrides, unsupported service tiers, settings preservation during revert, and settings checkpoints before user input when MCP startup is interrupted.
GitOrigin-RevId: e5ec012a5678048c5eedd443e524f38c142bf9fd
## Why
A delayed conversation classification can reach execution after a newer request has already published a score and committed history, leaving it with no useful work to contribute.
## What changed
Pass the classification's sampling timestamp into conversation requests and check for newer scores and retained history before starting inference. Return `Superseded` only when both have advanced; keep requests that can still contribute either a score or history.
## Testing
Add regression tests covering supersession of scores and history separately and together, including a classification delayed by permissions. Verify skipped requests send no inference request and preserve cached scores, approvals, and score progress.
GitOrigin-RevId: ef78a59e2010a82ac4f1fb93568a562447187099
## What changed
- Extend app-server tests for account credential reuse, refresh races, stale bearer rejection, retry exhaustion, and step-up failures at the identity provider and resource authorization server.
- Assert token-exchange request fields and enterprise protocol negotiation while preserving the ordinary MCP handshake.
- Add core scenarios for permission and tool-policy refreshes, policy revocation, and thread removal, including cancellation of in-flight enterprise calls.
- Snapshot conversation history after revocation to verify that prior calls remain visible and ordinary tools continue working.
- Allow the existing startup-failure test to wait through the MCP startup deadline.
GitOrigin-RevId: 31cf71a28f91bd30746b74df8fa669edb6bc23a1
## What changed
- Prefer an eligible account grant over saved enterprise credentials, with a fallback to saved enterprise sign-in during initial connection if the account grant is rejected.
- Remember rejected account grants per enterprise MCP registration across threads and report authentication failures as requiring reauthentication. Keep administrator configuration errors distinct from sign-in failures.
- Compare account grants independently of access and ID token rotation, recheck the latest identity eligibility after exchange, and retry once when the refresh grant changes.
- Make MCP authentication status reflect usable account grants, saved enterprise credentials, and completed connection failures.
## Testing
Extend regression coverage for enterprise sign-in failures and recovery, MCP authentication status, account grant identity across token refreshes, and retries after transient credential failures.
GitOrigin-RevId: eeac65f668d5d2d55e9d8bf4547fbcbdd6a6c42d
## 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
Pause Tokio time after the validation timeout in
`malformed_handshakes_preserve_active_streams_and_admission_recovers`
while inspecting diagnostics, since that inspection does not poll the
harness WebSocket for pings. Resume time before closing the WebSocket so
the close handshake and its timeout run with an active clock.
GitOrigin-RevId: 733a1fa35f80561424be97c4beb233780a7796cb
## Why
Dropped lifecycle facts can leave incomplete turns retaining analytics metadata indefinitely.
## What changed
- Limit retained turns to 256, evicting the oldest turn and its associated tool and review state when capacity is reached.
- Forward `ThreadClosed` notifications to analytics and discard the closed thread's turn and review state, including reviews received without turn lifecycle facts.
## Testing
Add regression tests covering metadata release after capacity eviction, continued reporting of new complete turns, cleanup isolated to the closed thread, and ignored approval responses after thread closure.
GitOrigin-RevId: eed0a1fef013381654345d535f03de42b99e8607
## Why
Guardian review metrics derived duration from wall-clock timestamps, while analytics measured elapsed time when tracking the result. Clock changes and delayed tracking could produce inconsistent latencies.
## What changed
Capture one monotonic duration at review completion and pass it to both metrics and analytics. Preserve wall-clock timestamps for event ordering, and saturate analytics latency conversion at `u64::MAX`.
## Testing
Add a regression test covering skewed wall-clock timestamps and delayed tracking, verifying that the duration metric uses the captured interval and completion timestamps are preserved.
GitOrigin-RevId: 19eafb8e1f1a3d13a751bdc72c218e4cafeae410
## 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
Store `RolloutItem::SessionMeta` and `RolloutItem::Compacted` payloads in `Box` values and update their producers, consumers, and test fixtures. Preserve the existing serialized rollout format.
GitOrigin-RevId: 59fcc4beb47d23160872dcb6e95ace9b142d3d11
## Why
Reducing code cell lifecycle events discarded their response payload references and lost the initial response status when the runtime status changed.
## What changed
Store the initial response status and separate raw payload IDs for the initial response and final result on `CodeCell`. Carry payload references through queued lifecycle events so they survive replay when the source item arrives later.
## Testing
Extend lifecycle tests to verify distinct initial and final payload IDs and the preserved initial status for yielded cells that complete and failed cells whose lifecycle events precede their source item.
GitOrigin-RevId: 8f49a3174ea487a5d91ebc2a6c97133aacaabfd2
## Why
Sessions using the same MCP catalog can repeat schema normalization and retain duplicate tool specifications.
## What changed
Split immutable MCP tool metadata and normalized specifications from per-handler caches, and reuse matching definitions within each `McpManager`. Require matching tool metadata, agent-plugin mode, and schema budget before reuse.
Keep shared definitions behind weak references and prune expired entries on cache misses so completed sessions do not keep their schemas alive. Build definitions outside the shared index lock.
GitOrigin-RevId: 02345359a1b0d297ca56f2f469de88aba89106f1
## Why
Targeted notification delivery and broadcast routing clone the message for every recipient, then discard the original.
## What changed
Use `std::iter::repeat_n` to move the original message to the last recipient, avoiding one clone per nonempty recipient list while preserving delivery behavior.
## Testing
Expand notification tests to cover empty, single, and multiple recipient lists, checking payloads, target order, and shared timestamps. Add broadcast coverage for zero, one, and two eligible recipients, verifying that uninitialized clients, clients without the required experimental API support, and clients that opted out are skipped.
GitOrigin-RevId: 2ba192f416ccd786e3566da3e5c851518b509afe
## Why
Disabled or failed protected shell snapshots prevent commands from running when credential masking is enabled.
## What changed
Restore unmasked credentials and continue execution when a protected shell snapshot is unavailable. Log and emit a warning explaining that the command will run with unmasked credentials.
## Testing
Extend `brokered_shell_snapshot_fallback` coverage for disabled and failed snapshots, including managed feature settings. Verify the warning, successful execution with restored credentials, continued filesystem sandbox and network policy enforcement, and masking recovery after snapshot storage is repaired.
GitOrigin-RevId: 28561e571b2a043d0b6cfa248c9ba2a61dd558ba
## Why
MCP callable namespaces and tool names can differ from their backend identities or match built-in tool names. Classifying calls by name can misidentify MCP calls and incorrectly parse namespaced `write_stdin` calls as terminal operations.
## What changed
Resolve `ToolCallKind::Mcp` from the runtime invocation's server and tool as soon as the runtime starts, before MCP correlation assignment. Preserve the caller-facing summary and raw invocation, and skip built-in runtime handling for MCP calls.
Only create dispatch-based `write_stdin` terminal operations for calls without a namespace.
## Testing
Add replay regression coverage for prefixed and unprefixed MCP aliases, names that match built-in tools, and `write_stdin` arguments with and without a session ID. Verify backend classification, preserved callable identity and dispatch lifecycle, and the absence of terminal operations and sessions.
GitOrigin-RevId: 71f31335c1eb36b6b7e1a34383d10fc500bd2c4f
## What changed
Move cached cloud skill contents into `SkillCatalogState` alongside the published catalog generation. Prepare auth scopes and access cached contents under the same lock, clearing contents when the auth scope changes and retaining them when a partial refresh preserves a complete catalog. Keep generation checks around asynchronous discovery and reads.
Use the auth key already captured by `prepare_cloud_generation` when creating a cloud plugin generation, so the stored and returned keys match.
GitOrigin-RevId: 426bb7868baf9ff7855988291783a8d3e38d9c93
## What changed
- Prefer stored enterprise credentials when available; otherwise use a validated Codex account OAuth grant whose issuer matches the enterprise MCP configuration.
- Pin each connection to its credential source and OAuth client, reject stale account grants, and hold the account refresh lease only during the IdP exchange.
- Report actionable sign-in and issuer configuration errors, and classify token failures by credential source.
GitOrigin-RevId: 26673f276a31e4ca5290f6b120f0ac44c77d7239
## Why
Configuration reloads must cancel stale enterprise MCP startups while preserving access for running threads that still pass validation. Replacing a runtime during `thread/revert` must also leave the replacement able to use enterprise tools.
## What changed
- Separate pending startup cancellation from published thread lifetimes, with independent startup state for forks and replacement runtimes.
- Retain eligible enterprise MCP connections across refreshes and explicit reconnects while applying updated tool restrictions and approvals. Do not create replacement enterprise connections after initial startup.
- Revoke enterprise authorization when a thread is removed, drain requests when access is disabled, and revoke a connection's authority when token renewal requires authentication.
## Testing
Extend regression coverage to verify enterprise tool calls survive `thread/revert`, inherited fork configurations are cancelled after a reload, and enterprise calls fail after logout while ordinary MCP calls remain available.
GitOrigin-RevId: 2d634be3011854b57f73c741bd1ec6b5aed94ee5
## What changed
- Add a `dsymutil` wrapper that delegates to the C toolchain's `LLVM_DSYMUTIL`, and include it in macOS Rust binary compile inputs and `PATH` so `rustc` can find it by name.
- Build macOS release staging archives with `--config=ci-macos`, `--remote_download_toplevel`, and `--build_metadata=VISIBILITY=PRIVATE`.
GitOrigin-RevId: 0f46520807dd9804049b6ae18351275af3693907
## What changed
Add an `incremental_tools` attribute to `codex.tools.registered` using the effective mode for the current sampling request. Compute the mode once and reuse it for registration metrics and prompt construction across transport retries.
## Testing
Extend integration tests to verify the attribute for incremental and non-incremental requests, including when the feature flag is enabled but the Responses API does not support incremental tools. Assert registration sample counts and retain coverage that stream retries do not duplicate registration metrics.
GitOrigin-RevId: e5b7a1075fe722ef6bdf900ae07e2b1b06aecfb5
## What changed
- Classify token-source failures by credential kind and exchange stage, with sign-in or administrator guidance that omits provider error text. Treat resource authorization failures separately from enterprise identity failures when deciding whether authentication is required.
- Add policy-bound request authority checks that return `RequestNotSent` when policy is updating or unavailable, while allowing admitted responses to finish. Support child authorities that isolate connection revocation and share response draining.
- Recheck account validity after acquiring the credential invalidation lock and check cancellation before deleting a rejected credential.
## Testing
Extend regression coverage for policy suspension during token renewal, completion of admitted requests, recovery with fresh authority, and transport retry classification. Expand provider-error tests to cover `unauthorized_client` and `invalid_client` while checking that credential text is not exposed.
GitOrigin-RevId: c0097adc35cb5fdffde1466e4bc2b5ec78114a4b
## Why
Legacy marketplace checkouts have no owner lock and were skipped by staging cleanup. Age thresholds allow cleanup to reclaim them while leaving recent clones from older binaries alone.
## What changed
Remove legacy `marketplace-add-` directories after 24 hours and `marketplace-upgrade-` directories after 10 minutes, based on directory modification time. Keep owner locks authoritative for current staging directories.
## Testing
Extend cleanup tests to cover both legacy age thresholds, preservation of recent legacy clones and live locked checkouts, and skipping legacy symlinks.
GitOrigin-RevId: 77b55bfe50ab29f5ceae46a80276b2c9e361107f
## Why
Failed marketplace adds can leave temporary checkouts behind, and interrupted adds or upgrades can leave abandoned staging directories.
## What changed
- Share a staging guard across marketplace adds and upgrades so temporary checkouts are removed on completion or failure, including config-write rollback.
- Reclaim up to four abandoned directories per cleanup pass during add and upgrade operations. Use file locks to preserve active checkouts and operating-system-specific names to avoid reclaiming another platform's staging directories.
- Skip symlinks and unrelated entries, and report cleanup failures as warnings.
## Testing
Add regression coverage for failed adds, CLI and automatic-upgrade cleanup, cross-process ownership and abandonment, lock contention, bounded cleanup, and symlink handling.
GitOrigin-RevId: 20999da0eab861dfb8025aad5e9fba2bcaf818b8
## What changed
- Add an account IdP identity resolver that checks ID-token bindings against trusted issuer and client provenance before discovering the refresh-token endpoint. An expired ID token does not by itself invalidate the refresh grant.
- Generalize `EmaIdpIdentity` and token exchange requests to carry caller-owned credential leases. Invoke a `finish_idp` callback after the IdP exchange and before resource authorization server I/O so callers can release their refresh guards at that boundary.
- Reject empty expected OIDC issuers and client IDs, and expose an unverified issuer hint solely for explaining legacy login migration.
GitOrigin-RevId: 34473fed82a9a6e58997664cd5e6e67049b5ee7e
## Why
Queued prompts can resume before a pending permissions menu opens, and local
`/permissions` commands can bypass guards for outstanding permission changes.
Attaching to a different project can also retain model access information from
the launch directory.
## What changed
- Route `/permissions` through app permission guards and hold queued prompts
while the menu is pending. Settle the hold when opening is rejected, discovery
is invalidated, or a covering request is resolved.
- Apply the custom permission profile selection check beyond embedded servers.
- Refresh API-key model access when the first attached session changes the
working directory, including with an embedded server. Propagate the widget's
model catalog to the app and server even when the model response matches the
widget's already-updated catalog.
- Skip sessions reported as `thread not loaded` during name lookup for all
server types instead of falling back to unverified list metadata.
## Testing
Add regression coverage for permission guards, queued prompts across successive
permission menus, invalidated and covered menus, model catalog propagation,
project changes on initial attachment, and name lookup across server pages with
unreadable entries.

## Why
A persisted login replacement can leave the auth cache holding the previous login, even for the same account. Enterprise MCP authorization must detect that replacement before continuing to use enterprise credentials.
## What changed
- Check cached and persisted account login ownership before enterprise MCP connections and around token exchanges, revoking authorization when ownership changes.
- Recheck account ownership and login generation before committing enterprise sign-in credentials.
- Compare complete token data when checking whether an account OAuth grant is still current, and expose grant token access and credential comparison helpers.
## Testing
Add regression coverage for detecting a same-account login replacement without updating cached auth, rejecting enterprise MCP use after replacement, and keeping ordinary MCP usable while an enterprise account storage read is blocked.

## 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.

## Why
Agent Plugin manifests previously skipped app declarations, including service-generated declarations installed with remote curated plugins. This prevented those plugins from using app routing and suppressing matching direct MCP connections.
## What changed
- Recognize app declarations for Agent Plugins from `openai-curated-remote` across loading, capability summaries, plugin details, tool suggestions, and install authentication.
- Apply app routing to suppress same-name MCP servers when an app route is available. Keep unrelated MCP servers available and preserve direct MCP access in API-key mode.
- Keep app declarations inactive for Agent Plugins from other marketplaces.
## Testing
Add coverage for marketplace and authentication routing, service-generated app declarations during installation with both manifest formats, and app tools reaching turns. Verify that disabling Apps does not restore matching direct MCP connections.

## Why
Decisions snapshot comparisons reject requests containing reasoning or compaction, while conversation comparisons already omit those items. A parent compaction also causes snapshot comparisons to be rejected.
## What changed
- Share filtering of reasoning, compaction, and context compaction across both comparison modes, and ignore parent compaction when building the Decisions request.
- Distinguish malformed request setup from unsupported input items. Record setup errors as failures and unsupported input items as skipped comparisons.
## Testing
Extend the HTTP contract test to cover both comparison modes with reasoning, compaction, context compaction, and parent compaction while preserving message content. Update assertions for the distinct setup and unsupported-input errors.

## What changed
Add `MessageLifecycleContributor` hooks to capture extension state when local agent control publishes a message and notify contributors when the recipient commits it to history, before sampling.
Carry shared delivery state through submissions, input queues, and mailbox eviction with `PendingAgentMessage`. Notify consumption at most once per delivery, release captured state when consumed or abandoned, and drop pending mail outside queue locks. Preserve the serialized message format without republishing restored history.
## Testing
Extend the mailbox eviction test to verify that publication state survives eviction and retained messages are consumed before the first resumed model sample.
