## 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`.

The initial user item seals realtime transcript segments, so starting speech before it completes can split the segment under test. Wait for its `item/completed` notification and assert that it is a `ThreadItem::UserMessage` before triggering speech, so only the steering under test can split that segment.
GitOrigin-RevId: 932443f4a0d6c4284cf95f44e64912506769a180
## What changed
- Add the disabled-by-default `output_token_replay` feature to request `output.encrypted_content` from OpenAI providers.
- Preserve encrypted message and tool-call output, message and function-call status, and output-text `annotations` and `logprobs` through history and replay. Update the generated protocol schemas and SDK types.
- Strip output ciphertext from requests to other providers while retaining it in stored history, including after replay is disabled. Remove encrypted content from memory extraction inputs.
## Testing
Add integration coverage for the feature/provider combinations, metadata replay across follow-up requests, and history preservation when resuming with replay disabled.
GitOrigin-RevId: 77729a021b6771933402aebe74ece8eb39c057e2
## Why
Graceful shutdown rejects new sessions with an invalid-request error. Give clients a structured shutdown reason and show command center users why session creation is paused.
## What changed
- Add `data: {"reason":"serverShuttingDown"}` to app-server shutdown admission errors while retaining JSON-RPC code `-32600`.
- Show a dedicated shutdown message explaining the wait for active turns and automatic reconnection for non-embedded servers. Recognize older servers by their exact draining message only when error data is absent, and preserve retained-worktree cleanup guidance.
- Keep the command center reconnect presentation when a shutdown error covers the initial overview and no conversation is open.
## Testing
Extend admission and WebSocket shutdown assertions, add embedded and daemon shutdown message snapshots, and cover reconnection with a shutdown error over the initial command center.
GitOrigin-RevId: f167144c0ddc77872afdf3daac8bb1c89f3425b4
## What changed
Pass the parent turn's `cyber_access_program` to Guardian reviewers and asynchronous classifiers. Use `daybreak_blue` for either Daybreak selection, preserve `standard`, and omit `access_programs` when no program is selected.
Capture the selection with the owning turn so asynchronous observations retain it across later turns. Resolve classifier programs using current authentication and the same provider and API-key feature policy as ordinary model requests.
## Testing
Add regression tests for program changes across reused reviewer sessions with API-key and ChatGPT authentication, snapshot and conversation classifiers at low and high risk, and enabled, disabled, and unsupported-provider API-key policies. Verify parent requests retain their selected program.
GitOrigin-RevId: 447f306df3a6bd6805464b819950690c751b04b4
## What changed
Add an optional `retain` flag to `TurnToolOutput` for `turn/start`. When set to `true`, pass the output to the core with a retention annotation to request retention in the thread's model history. The flag defaults to `false`, preserving existing behavior.
Update the generated JSON schemas, TypeScript types, and Python bindings to expose the flag.
## Testing
Add an integration test verifying that a retained tool output reaches the model and preserves client-authored sender metadata in persisted history, including the receiver message ID.
GitOrigin-RevId: 52893a8fcb308f26e77ba8f0bee9990073b26d54
## Why
Interrupted automatic goal continuations reset the empty-response counter, allowing repeated interruptions without activity to keep a goal running indefinitely.
## What changed
Count interrupted automatic continuations without activity toward the existing three-turn limit that marks a goal as `blocked`. Defer evaluation until the thread is idle and serialize it with turn-start accounting. Activity and user turns still reset the counter.
## Testing
Extend accounting tests to cover interrupted and mixed empty continuations, including resets after tool activity or user turns. Add an app-server regression case where a `PreCompact` hook repeatedly interrupts automatic continuations and verify the `thread/goal/updated` notification reports `blocked`.
GitOrigin-RevId: 4c34e3ed1ae612e97cf067c2aa76836b10c50ef5
## What changed
Add `thread/items/read` to retrieve persisted items by `threadId`, `turnId`, and 1–100 `itemIds`. Return matching items in canonical stored order, omitting missing IDs and items outside the requested turn.
Add item ID filtering to the thread store while preserving inherited history and fork cutoffs. Require the experimental API capability for the new endpoint.
## Testing
Add coverage for stored ordering, turn scoping, missing IDs, request size limits, experimental capability gating, and inherited items across fork cutoffs.
GitOrigin-RevId: 9b243dd87577bd4fe36900c388a386b2e26ff2e0
## Why
Background workspace routing reads reload configuration even when signed out or using an API key, although routing requires ChatGPT authentication.
## What changed
Check cached authentication before reading accounts for workspace routing at app-server startup and connection initialization. Skip these background reads without ChatGPT authentication, while preserving configuration reloads for explicit `account/read` requests.
## Testing
Add regression tests covering signed-out and API-key startup and connection initialization, explicit `account/read` configuration reloads, and routing after ChatGPT sign-in, including propagation of configuration errors.
GitOrigin-RevId: 8b90ee609ed24f8618cd21f160eb7001703b8bd1
## Why
Clients need to mark threads read or unread without overwriting unseen results or another window's explicit mark.
## What changed
Add `thread/readState/update` for eligible durable local threads, gated by `initialize.capabilities.experimentalApi`. Requests include `threadId`, `expectedRevision`, and an operation of `{type:"read"}` or `{type:"unread"}`.
Marking read clears `firstUnread`; marking unread sets it to `threadStart`. Successful updates return the read state and notify subscribers through `thread/readState/changed`. Both operations require an exact revision match. Stale requests return `-32600` with `readStateConflict` and the current read state, requiring a fresh user action rather than a blind retry. Updates do not change thread recency.
## Testing
Add app-server coverage for experimental capability gating, explicit unread marks and notifications, conflicts for both stale operations, and marking read with a fresh revision.
GitOrigin-RevId: 775f6e9584dc91bd3c2ee9a309144b5baf0edffa
## What changed
Add the experimental `thread/readState/changed` notification with `threadId` and the committed `readState` receipt. Send it to existing thread subscribers when terminal activity updates read state or a revert clears a removed unread position. Emit terminal read-state updates before `turn/completed` so completion remains the last notification for that result.
Expose the notification in generated JSON schemas, TypeScript types, and Python SDK models. Document experimental capability gating, subscription lifetime, notification opt-out, and refreshing receipts when concurrent responses disagree.
## Testing
Extend the read-state integration test to assert that the notification receipt matches the receipt returned by `thread/read` after terminal activity.
GitOrigin-RevId: 28935352a881b7a5e2e7f629173c3b2061bd7941
## Why
Realtime v3 voice validation used the v1 voice list, limiting the available voice choices.
## What changed
- Add a dedicated `v3` voice list containing the v1 voices and 16 additional voices, and use it to validate v3 requests.
- Expose `v3` in `RealtimeVoicesList`, defaulting to an empty list when omitted during deserialization.
- Update the configuration and app-server schemas, generated TypeScript and Python types, and voice-list test expectations.
GitOrigin-RevId: 7fc8060fe01d840f28eb92c3dfe49c5878c3c258
## What changed
- Add experimental `readState` to `thread/read` and a thread-ID-keyed `readStates` map to `thread/list` for eligible durable local user threads. Each receipt contains `firstUnread` and an opaque `revision`.
- Publish new visible terminal results before `turn/completed`, after flushing the rollout. Reading snapshots leaves activity unread; replayed history does not publish new activity.
- Clear unread positions removed by a paginated thread revert while preserving explicit thread-start marks and concurrent receipt updates.
## Testing
Add an integration test covering completed-turn receipts, repeated reads without acknowledgement, matching list receipts, and revert cleanup with a changed revision.
GitOrigin-RevId: e7f6ddfbb1fc2fa95d1ef2876d7f0f7b9f99ff65
## What changed
- Remove `ContentItemMetadata`, provenance and namespace types, and the `content_item_metadata` protocol field while retaining `content_item_kinds` classifications.
- Simplify context fragments, extension contributions, and hook output to carry content without source attribution. Return MCP tool results directly without an attribution wrapper.
- Render context-window hints together in a single text fragment.
## Testing
Update Responses and Responses Lite request assertions to expect content-kind classifications without per-content attribution, and adapt context, hook, and extension tests to the simplified types.
GitOrigin-RevId: 201894cd4c93c6d4b4c41c845e7a9af1dd3c95ca
## What changed
Add `history_initialization` to `x-codex-turn-metadata`, distinguishing `new`, `cleared`, `cold_resume`, `warm_fork`, `cold_fork`, and `supplied_history`.
Classify forks by whether the source runtime is loaded and has not shut down. Preserve the classification for the runtime's lifetime, including warm resumes and compaction. This records how history was initialized; it does not establish whether tool metadata is missing. Reserve the field against client-supplied overrides.
## Testing
Extend coverage for warm and cold forks, cold resumes, warm reconnects, supplied history, WebSocket metadata serialization, and reserved-field filtering.
GitOrigin-RevId: 468153512a84d0f4d4ea742198a29e0fa3873a72
## Why
Durable remote-control RPC changes need to update the managed daemon's launch settings so future launches use the saved preference.
## What changed
- Save non-ephemeral `remoteControl/enable` and `remoteControl/disable` requests to `remoteControlEnabled` in `app-server-daemon/settings.json` for managed daemons.
- Preserve other settings and write updates atomically. Skip persistence when `daemon.lock` is held so concurrent lifecycle operations take precedence without blocking the RPC.
- Leave daemon settings untouched for ephemeral requests and unmanaged servers.
## Testing
Add integration coverage for durable enable and disable, ephemeral requests, and lock contention. Extend the unmanaged-server test to verify that no daemon settings file is created.
GitOrigin-RevId: 2baf261ed62f7c7ad87c9779ffb91c59e923f0f8
## Why
Disabling OpenAI analytics also disabled explicitly configured OTLP metrics collectors. Users should be able to export metrics to their own collectors independently of `analytics.enabled`.
## What changed
Apply the analytics preference only to the built-in `statsig` metrics exporter. Keep custom OTLP HTTP and gRPC exporters enabled regardless of that preference, and use `otel.metrics_exporter = "none"` to disable metrics export. Clarify these settings in config documentation and the schema.
## Testing
Cover exporter selection across explicit and default analytics preferences. Update app-server and daemon telemetry tests to verify custom metrics export with analytics disabled, and worktree tests to disable metrics through the exporter setting.
GitOrigin-RevId: 0c61f0f01e2b694db642ac7e7fd1dac9965c7d96
## What changed
- Reformat Markdown tables and lists, login pages, inline visualization HTML, and sample JavaScript scripts.
- Escape union-type pipes in Python SDK API tables so they render within their cells.
- Keep the formatting-recipe test focused on the working directory and formatter commands by removing assertions on comment text.
GitOrigin-RevId: ae46d5b40fd013553de8b5ccf2c41d76be65aba8
## What changed
Add the disabled-by-default `guardian_trust_orchestrator_connectors` feature flag. When enabled, Guardian V2 accepts connectors with nonblank IDs from the host-owned plugin service orchestrator as a trusted source without requiring a matching user configuration declaration.
Distinguish orchestrator provenance from user configuration in trusted-tool context. Trust remains scoped to the exact server or connector identity and source; descriptions, outputs, other tools, and other connectors remain untrusted.
## Testing
Add coverage for host-owned connector context, rejection of extension-owned Apps lookalikes and blank connector IDs, source-specific trust metadata, and context token limits. Snapshot the connector approval request history.
GitOrigin-RevId: fbd87dd71110ca7b2b92d50eef02e1e739a74a02
## Why
Subagents should retain the spawning turn's selected skills and plugin choices whether `fork_turns` is `none` or `all`. Capability selection should not depend on copied conversation metadata.
## What changed
- Use a shared child startup path for fresh and history-forked agents, inheriting selected capability roots from the spawning environment snapshot.
- Pass the spawning turn's `disabled_plugin_ids` through both spawn handlers. When omitted, inherit the parent's current choices; explicit lists, including an empty list, override them.
- Resolve the parent before startup so inherited client MCP settings apply even when only the session source identifies the parent.
- Carry plugin choices into delegates with inherited isolation and preserve saved capability roots when resuming a child.
## Testing
Add regression coverage for executor skill listing and reading, plugin MCP registration with both history modes, plugin overrides, capability-root precedence and isolation, and restoring saved child settings after parent settings change.
GitOrigin-RevId: 2a6891a9bc6372fd2d1f30add2b5611f96b60594
## What changed
- Add optional `websocketRequestId` to `environment/add` and send it as `X-Request-ID` on direct WebSocket upgrades, including reconnects. It requires a secure transport or a loopback destination.
- Echo a supplied `X-Request-ID` in the exec-server WebSocket upgrade response.
## Testing
Add coverage for `websocketRequestId` serialization and for handshake header forwarding and echoing, both with and without a request ID.
GitOrigin-RevId: 235303ff7e1150405b7e1158d6024223144e0cc3
## What changed
Support `plugins._default.enabled` with explicit per-plugin `enabled` overrides. Omission preserves existing source and account enablement; configuration cannot activate a plugin disabled at its source. Plugin settings such as remembered tool approvals inherit the default unless `enabled` is explicitly set.
Apply the policy to plugin skills, MCP servers, Apps, and hooks, including selected executor roots and runtime configuration refreshes. Preserve the latest plugin policy when adding MCP dependencies and rebuild hooks when concurrent configuration updates replace their inputs.
Report effective enablement in `plugin/list`, `plugin/installed`, `plugin/read`, and `plugin/share/list`. Remote installation still installs disabled packages, but skips MCP and Apps authentication setup without writing an enablement override.
## Testing
Add regression coverage for default inheritance and explicit overrides, source-disabled plugins, policy refreshes during active turns, disabled or malformed selected plugin roots, and remote installation authentication behavior.
GitOrigin-RevId: 83b70c5b47fc95474fec292f248683f1f887221e
## What changed
- Add `ContentItemMetadata` to distinguish user input, developer instructions, `AGENTS.md`, skills, harness context, and tool-supplied context independently of message role and content classification.
- Keep attribution attached to content through prompt assembly, history processing, and hook-output spilling. Distinguish command hooks from MCP hooks and retain tool namespaces when known.
- Treat missing historical attribution as unknown and send per-content metadata only to Responses Lite.
## Testing
Update request and history assertions to cover attribution persistence and Responses Lite metadata handling.
GitOrigin-RevId: 24e56005f5bdb98bf82f2b3943f29c4c81f3d587
## What changed
Add `windows.require_mxc` to managed requirements. When set to `true` on Windows, reject configurations whose effective local sandbox backend is not MXC without changing the selected backend.
Validate after cloud configuration loads and outside startup recovery fallbacks. Apply the check to app-server startup and configuration loads, in-process bootstrap, session creation, sandbox debugging, and runtime configuration refreshes.
## Testing
Extend configuration tests to cover required and optional MXC selection, separately loaded policy requirements, and runtime refresh validation. Expand app-server startup tests to cover local and cloud MXC requirements, cloud preference selection, and failures without default-config recovery.
GitOrigin-RevId: 16456611bfd9df77e7f959b52515f1885b59ac75
## What changed
- Use the standard shell executor and remove the zsh fork escalation runtime, `codex-execve-wrapper`, and `shell-escalation` crate.
- Ignore `shell_zsh_fork` and `unified_exec_zsh_fork`, emit migration notices for legacy configuration, and warn when ignoring managed requirements for these flags.
- Keep the active session's `apply_patch` alias directory readable under restricted filesystem permissions.
## Testing
Add coverage for legacy configuration startup and shell execution, migration notice rendering, active alias directory selection, and nested `apply_patch` execution while other files in `CODEX_HOME` remain unreadable.
GitOrigin-RevId: 43af461fea32b4980550ee7237effd2bc0646ed8
## Why
Persisted multi-agent v2 children created after the client disconnects need lifecycle listeners so their runtimes can be released once idle. Listener attachment must also wait for an earlier runtime's cleanup to finish.
## What changed
- Start lifecycle listeners for persisted v2 children even when no initialized clients are connected, and defer attachment until pending unload cleanup completes.
- Keep ephemeral children loaded so follow-up tasks retain their model context.
- Raise the default `thread_unload_delay_secs` from 60 seconds to 1800 seconds (30 minutes), updating the configuration documentation and sample.
## Testing
Add regression coverage for children spawned after disconnect with zero- and one-second unload delays, including waiting for pending cleanup, keeping running threads loaded, releasing idle runtimes, and preserving an ephemeral child's earlier reply across a follow-up. Update configuration tests for the new default and explicit overrides.
GitOrigin-RevId: 2fecc77b5c03237aa8fd7eacc4bd119b99d36e0a
## Why
A conversation classifier waiting for preparation or full response completion can block newer classifications. Concurrent reviews also need to prevent a later action's evidence or low-risk score from being reused for an earlier action.
## What changed
- Run conversation classifications independently, forking the latest compatible completed history from an earlier action. Only a valid completion with a newer action index can replace retained history.
- Keep admission and observation ordering atomic, and hold capacity permits through full response completion.
- Reject cached low-risk scores from later actions for tool-linked approvals, including initial approval checks.
- Track originating tool-call IDs separately from approval display IDs, preserving stdin write provenance and excluding synthetic MCP elicitation IDs from tool ordering.
## Testing
Add regression coverage for delayed preparation, capacity admission, out-of-order completion, cancellation, invalid retained output, and history snapshots. Exercise pending approval ordering in both `snapshot` and `conversation` modes, and verify linked and unlinked MCP elicitation provenance.
GitOrigin-RevId: 097476ccb3b8718369a69f55c3c39132f7f1a4c1
## What changed
- Route app-server idle unloading of multi-agent v2 children through local eviction that preserves unread mail and environment selections for reload.
- Hold residency pins through input submission so newly reloaded children cannot be evicted before receiving their work.
- Guard listener cleanup against replacement runtimes and subscriptions, and reject local eviction of host-controlled threads.
## Testing
Add coverage for unsubscribe-driven eviction followed by `followup_task`, verifying restored conversation context and exactly-once delivery of queued mail. Extend tests to check that residency pins block eviction and that rejected host eviction preserves the thread and mailbox.
GitOrigin-RevId: e36723730af683d2081e495e637f0e6d23548b8d
## What changed
Record local MXC availability and the selected Windows sandbox backend at app-server and session startup. Log the backend again when an accepted session settings update changes the Windows sandbox level, using a blocking task for the log write.
Selection entries distinguish `mxc`, `disabled`, `unelevated`, and `elevated` in the sandbox logs under `.sandbox` in Codex home.
## Testing
Update the remote thread persistence assertion to allow the `.sandbox` directory on Windows, since startup logs are not thread persistence artifacts.
GitOrigin-RevId: 4130b59ac7761223775ac9b6afb096abb7fb4615
## Why
Compaction analytics lack a voice session ID. A compaction event can arrive after its voice session has closed or another session has started, so attribution needs to account for when compaction began.
## What changed
Add `voice_session_id` to compaction events. Track realtime session starts, ID updates, and closures, retaining up to 16 recent closed session windows. Resolve the session from the compaction start timestamp, falling back to the turn's voice session ID.
Forward realtime session ID updates from the app server to analytics and update the active turn's attribution.
## Testing
Add coverage for realtime session boundary facts, compaction event serialization, and delayed compaction events across consecutive voice sessions.
GitOrigin-RevId: 981da0ea2c38a87079b6bab33daf2c88fd95160f
## Why
Prediction forks need to preserve the parent's effective context and request settings to maximize prompt-cache reuse.
## What changed
- Add `experimentalPredictionMode` to `thread/fork` for ephemeral forks of loaded, persisted parents. Reject configuration overrides, `path`, `lastTurnId`, and `beforeTurnId` in this mode.
- Inherit the parent's effective configuration, tools, environments, collaboration settings, disabled plugins, and persisted history.
- Enable `features.reasoning_effort_override` on the fork while preserving the parent's request-effort baseline, including when overrides were disabled on the parent.
- Report the fork's effective model, service tier, and reasoning effort in the response.
## Testing
Add coverage for matching parent and fork requests and prompt-cache keys across legacy and paginated history, invalid fork parameters, and reasoning-effort inheritance. Add a context snapshot for identical parent and fork continuations.
GitOrigin-RevId: 46b41f2ac331562b441dadff1a0a9f926c94880d
## Why
Global requests can inherit project settings from the app-server's launch directory. This can prevent marketplace removal or expose project-only feature settings, and config reloads can fail if that directory is deleted.
## What changed
- Load configuration without project context when no working directory is supplied, using `CODEX_HOME` to materialize `Config.cwd`.
- Use global configuration for marketplace mutations, marketplace upgrade reloads, and MCP requests without thread context.
- Pass the launch directory explicitly during startup to preserve project-aware startup configuration.
## Testing
Update regression tests to verify that marketplace removal ignores launch-project configuration and leaves the project config intact. Extend feature-list coverage to verify that global requests ignore project features, thread requests retain them, and global requests work after the launch directory is deleted on Unix.
GitOrigin-RevId: b77063a7ea0b09fd0a79cfc4040db9f1d02606b3
## Why
Detect changes to the default model-visible prefix relative to a released CLI, requiring those changes to be gated behind a default-off feature key.
## What changed
Add `prompt_prefix_matches_release` to compare instructions, tools, and input preceding the user message using the same client and inputs. Each binary uses its bundled model catalog and feature defaults. The comparison removes response item IDs and transport metadata and normalizes fixture paths and session identifiers while preserving prompt text, whitespace, tool descriptions, schemas, and array ordering.
Use the released binary supplied by `CONTRACT_EXECUTOR_BIN` when available; otherwise, compare two runs of the current binary to check determinism.
GitOrigin-RevId: 1a69fb3abb6fc3df90a095e01bcf0d5de1818fac
## What changed
- Add `runtime_package` targets for combined, primary, app-server, and Windows helper bundles, plus per-binary release archives.
- Apply release settings automatically and retain unstripped binaries with macOS dSYM or Windows PDB symbols. Require platform-specific symbols and validate that dSYM bundles contain nonempty DWARF data.
- Support a `debug` build mode for faster package smoke builds and configure platform-specific release settings, including native Windows MSVC toolchains.
- Add a composite action that refreshes Cargo workspace metadata, builds the selected archive, and extracts writable files for existing signing and packaging steps.
GitOrigin-RevId: 21109875cde228aaef67b2ba9812b3e4854aee84
## What changed
Wire existing sandbox integrity checks into local command preparation, exec-server process preparation, and sandboxed filesystem helper and file-open operations. Make execution request preparation asynchronous so callers can await the checks.
The checks remain observational: failures and timeouts do not prevent command execution.
## Testing
Add regression tests that launch a real command after checker preparation fails or exceeds its timeout, verifying successful output and exit status.
GitOrigin-RevId: a82399f8aeb8b08f9965e6121b4c7f460552af3f
## Why
User-verification cancellations previously discarded failure reasons, leaving MCP servers unable to distinguish user cancellation from unavailable approval, interruption, or invalid proof.
## What changed
- Carry a bounded `openai/userVerificationReason` value in response `_meta` for verification failures, declines, and cancellations across the TUI, app server, and MCP client.
- Preserve recognized reasons and classify invalid responses, missing or invalid proofs, response errors, closed response channels, interruptions, and unavailable approval.
- Discard unknown reasons and unrelated metadata. Keep proof material out of decline and cancellation responses, and keep display messages and raw error diagnostics out of response metadata.
## Testing
Add and update tests for typed failure propagation, metadata filtering, invalid proofs, response-channel failures, interrupted requests, and unavailable approval, including TUI RPC and native MCP response coverage.
GitOrigin-RevId: 6b7f855ce8eb13e759b5b86d0dc2b1afdfcff7b3
## What changed
Add the `ultrafast` service tier to bundled catalogs for `openai.gpt-6.1-sol` on Bedrock Mantle and `global.openai.gpt-6.1-sol` and `us.openai.gpt-6.1-sol` on Bedrock Runtime. This exposes `/ultrafast` for these models while keeping tier selection opt-in.
## Testing
Extend catalog, app-server, core request, and TUI tests to cover GPT-6.1 Sol tier discovery and selection across all three model IDs, including toggling back to the default tier and honoring custom catalog commands.
GitOrigin-RevId: b5bbde8615b73a1d73eb16db7952b10d044b9fa6
Background discovery can cache a successful response before the test mounts
its unauthorized-response mock, bypassing the intended token refresh.
Mount the `401` mock before invalidating the route cached during login in
`external_auth_refreshes_on_unauthorized`.
GitOrigin-RevId: 8c280ca7287dab09230d534a44ca80d0835d2ef2
## Why
Failed Guardian review evidence was process-local, so restarting Codex lost the context needed for later diagnostic reports.
## What changed
- Persist failed-review records in SQLite before reviewer cleanup, retaining at most 64 records globally, eight per thread, and 8 MiB of evidence. Delete persisted evidence when its reviewed thread is deleted.
- Recover and deduplicate persisted and in-memory records for the reported task tree when uploading `auto-review-failures.jsonl`.
- Bound persistence attempts to 250 ms and retain an in-memory fallback when storage is unavailable. Keep capture gated by user opt-in and non-ephemeral sessions, and export evidence only when logs are included.
## Testing
Add coverage for persistence across reopen and process restart, retention limits, cascading deletion, busy-storage fallback, and report uploads with and without logs, including SQLite log failures.
GitOrigin-RevId: ea2da1818d4a5da3da29f211042ca45e834342bc
## Why
Retained assistant context changes as the conversation grows. Keeping it separate from retained user instructions lets independent Guardian snapshots preserve a reusable instruction and transcript prefix.
## What changed
Move retained user instructions before the transcript and place assistant originals and their omission notice in a separate `RETAINED ASSISTANT CONTEXT` section afterward. Preserve evidence, delivery roles, source metadata, and deduplication across both retained sections. Clear omission delivery metadata when a split assistant notice cannot be attributed to a single section.
## Testing
Add regression coverage for prefix stability as assistant context and previous reviews change, evidence preservation, repeated preparation, and deduplication. Update approval-routing and scorer tests to check the new section order and retention of assistant text outside a smaller transcript budget.
GitOrigin-RevId: 15cda59d24bee0106f6a66c067f6a790fa91df69
## Why
DB-only listing and pagination failures must not look like exhausted history. This hardens the DB-only listing added in https://github.com/openai/codex/pull/18502 and page refilling added in https://github.com/openai/codex/pull/7509.
## What changed
- Return JSON-RPC error `-32603` when `useStateDbOnly: true` cannot query the local state database, including requests with an empty `cwd` array.
- Track all cursors encountered while filling a page and return `-32603` for repeated cursors, including on full pages.
- Document that callers can retry these errors; a successful response with `nextCursor: null` still indicates exhaustion. Default scan-and-repair requests retain their filesystem fallback.
## Testing
Add regression tests for missing or mismatched state databases versus healthy empty history, with active and archived listings and null or empty `cwd` filters. Cover repeated cursors during page refilling and on full pages using the in-memory thread store.
GitOrigin-RevId: 09653a84fc65f47316d8bbae9e4cf3dd8ce9948a
## Why
Clients displaying a saved manual thread order need to list the remaining threads without repeating those already loaded separately.
## What changed
Add optional `excludedThreadIds` to `thread/list` and the generated protocol bindings. Apply exclusions before the result limit, refilling pages until the requested limit is reached or history is exhausted while preserving existing filters and ordering. Clients must send the same exclusions on each page.
Accept up to 100 entries, counting duplicates toward the bound. Reject invalid IDs or oversized lists with JSON-RPC error `-32602` rather than truncating them. Omitted, null, and empty lists preserve existing behavior.
## Testing
Add integration coverage for page refill across database-only and scan/repair paths, archived threads, sort directions, and project/section scopes. Cover duplicate and unknown IDs, the 100-entry boundary, invalid input, and preservation of section order.

## What changed
Remove `workspace_roots`, `current_date`, `timezone`, `network`, `personality`, and `multi_agent_mode` from `TurnContextItem` and stop recording them in rollouts. Update the precomputed protocol schema accordingly.
Make `summary` optional when reading turn context and write `"none"` as a compatibility placeholder for older readers, rather than persisting the active reasoning-summary setting.
## Testing
Update protocol tests to cover omitted `summary` fields and compatibility-placeholder serialization. Extend compaction tests to verify that model requests retain the updated reasoning-summary setting after compaction while the rollout checkpoint records the placeholder.

## Why
Skill selection and disabled-path matching need to recognize equivalent Windows paths across case and separator differences while preserving literal spaces, `%`, and `#` in native filenames.
## What changed
- Carry `PathUri` through skill metadata, discovery mappings, filesystem lookups, disabled-path sets, and invocation analytics.
- Match linked skill mentions and TUI selections by parsed path identity.
- Use `LegacyAppPathString` for app-server skill paths and regenerate schemas and SDK types, preserving native path strings on the wire.
- Preserve native catalog display paths and ordering. Keep host filesystem probes and configuration writes restricted to host-compatible paths.
## Testing
Add regression tests for Windows path identity and disabled-skill matching, literal filename characters, catalog resource reads, native path ordering, and foreign-path analytics normalization.

## What changed
For managed app-server daemons using Unix sockets, raise the soft
`RLIMIT_NOFILE` limit to 4096 at startup, capped by the inherited hard limit.
Preserve existing higher soft limits and log a warning if the adjustment fails.

## Why
Submission diagnostics need approval and turn metadata without logging user input, tool responses, commands, paths, or instruction payloads.
## What changed
- Log thread and submission IDs, operation kind, and parent/root turn IDs as explicit fields.
- Give `Op` and `ThreadSettingsOverrides` selective `Debug` output that retains identifiers, approval decisions, and policy categories while omitting payloads.
- Preserve Guardian review identifiers and status when logging approval of a denied-action retry.
## Testing
Add an app-server integration test that verifies command approval, Guardian review, and turn policy metadata reach SQLite-backed diagnostic logs with `RUST_LOG=off`.

## What changed
Add `model` and `reasoningEffort` to `subAgentActivity` items for multi-agent v2 spawns. Capture startup settings before the child begins its turn and resolve the reported effort against model metadata, including model defaults, while preserving the child's configured effort.
Carry these fields through live notifications, persisted activity, thread history, and legacy rollout migration. Update the JSON schemas and generated TypeScript and Python types. Older records and other activity kinds retain null values.
## Testing
Add coverage for resolved spawn settings matching the child's request across legacy and paginated history, preserving configured effort, forwarding metadata through events and history, and reading and migrating older records without the new fields.

## What changed
Add `TurnEnvironmentRequests` to carry environment requests together with their fallback working directory. Update thread settings overrides and active turn settings to accept requests, constructing `TurnEnvironmentSelection` values in the receiving thread before validation and runtime use.
Adapt app-server callers, reviewer settings, and existing tests to supply requests or explicitly convert runtime selections back into requests.

## Why
Idle thread unloading stopped waiting after ten seconds, leaving the thread loaded when resource cleanup took longer.
## What changed
Keep awaiting the same shutdown future after the ten-second deadline, emitting `codex.app_server.thread_shutdown_slow` as a warning. Once shutdown completes, remove the thread and send `thread/closed` without requiring another unload request.
## Testing
Add a regression test that blocks writer-lock cleanup past the warning deadline, verifies the thread remains loaded while cleanup is blocked, then releases the lock and checks for `thread/closed` and an empty loaded-thread list.

## Why
Clients starting delegated work need to attribute descendant turns to the original turn and retain that attribution through completion and history reads.
## What changed
- Accept optional `parentTurnId` and `rootTurnId` in `turn/start`, and expose `rootTurnId` on returned turns and lifecycle notifications.
- Default new turns to their own root when none is supplied. Preserve the active turn's root when steering, ignoring incoming lineage fields.
- Carry root IDs through completion, interruption, recovery, and fork boundaries, and persist them for paginated history reads. Leave unknown roots null in older history.
- Update protocol schemas and generated TypeScript and Python bindings.
## Testing
Extend coverage for default and explicit roots, steering without changing lineage, interrupted and recovered turns, history reads after restart in both history modes, nested fork pagination, and compatibility with older database writers.
