## Why
Some metrics backends require cumulative metrics, while configured OTLP exporters previously always used delta temporality.
## What changed
Read `OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE` for configured HTTP and gRPC metrics exporters. Accept `delta`, `cumulative`, and `lowmemory` case-insensitively, retaining delta for unset, empty, or unrecognized values. Document the setting and preserve existing temporality for the built-in Statsig exporter and runtime snapshots.
## Testing
Update the HTTP loopback test to set the preference in an isolated subprocess and assert that the exported counter uses cumulative aggregation temporality.

## What changed
- Carry opaque `review_target` values through misalignment errors and expose optional `reviewTarget` in the app-server protocol and generated clients. Preserve the value verbatim and redact it from debug output.
- Keep target-based `misalignment_override` metadata on turn requests, preserve it across steering updates, and exclude it from compaction and external MCP metadata. Reject overrides from global Responses metadata while retaining legacy timestamp behavior for per-turn overrides.
## Testing
Extend coverage for error propagation, debug and rollout redaction, steering preservation, and metadata filtering. Verify that automatic compaction omits the review target while turn requests before and after compaction retain it.
GitOrigin-RevId: 8c1abb076a206ff5927a4acc31bd25e3efc2bff9
## What changed
Record the total serialized JSON size of raw MCP tool definitions in the `codex.mcp.binding_catalog.raw_definition_json_bytes` histogram, before filtering or model preparation.
Emit an `mcp.binding_catalog` trace event for each server with its tool count, definition size, server kind, plugin ID, and cached or live catalog source. Reuse bounded product SKU attribution for both metrics and events, and skip size measurement when neither telemetry output is enabled.
GitOrigin-RevId: abda7cbf46d5470eb321455f047dd7429084740e
## Why
Bubblewrap discovery probes executables before confinement. Excluding only the command's current directory leaves candidates in other writable roots eligible to run outside the sandbox.
## What changed
- Filter canonical `PATH` candidates using the filesystem policy and effective user permissions, including writable ancestors, symlinked roots, and full-disk write access. Preserve protected system installations while rejecting replaceable paths.
- Select the launcher with the command's permissions before the proc-mount preflight, retaining the bundled bubblewrap fallback.
- Use the effective permission profile and policy working directory for startup warning probes.
## Testing
Add unit coverage for writable roots, symlinks, read-only carveouts, replaceable parents, and full-disk policies. Add Linux integration tests showing writable `bwrap` candidates are neither probed nor launched, including when the command runs in a workspace subdirectory or uses managed networking with full-disk write access.
GitOrigin-RevId: 188c9f45e727eaace062f5abb1205dc23fdf3c51
## What changed
- Add the default-disabled `code_mode_tool_search` feature to expose `await tools.tool_search({query: "...", limit: 8})` in code mode when the model supports tool search.
- Return BM25-ranked deferred tools as `{tools: [{name, description}]}`, including callable names and TypeScript declarations for use in later code cells.
- Filter results through the current step's nested-tool policy before applying the limit, preserving namespace restrictions, normalized identities, description prefixes, and schema budgets.
- Add ranked-search guidance while retaining `ALL_TOOLS` catalog discovery and description overrides.
## Testing
Add coverage for feature and model-capability gating, namespace restrictions, argument validation, schema budgets, and discovery followed by deferred MCP and dynamic tool calls. Extend the scenario snapshot to cover search, invocation, yielding, and completion through `wait`.
GitOrigin-RevId: 092a29dd5f0773c518f53a001b9cafb917422f13
## What changed
Add `features.cli_daybreak`, disabled by default, to gate Daybreak controls and automatic access-program selection in the TUI and `codex exec`. Apply the gate to resumed sessions and background task turns, and hide `/daybreak` when disabled. Explicit `--cyber-access-program` overrides remain available.
## Testing
Extend tests to cover disabled controls, history replay, foreground and background turn requests, exec resume/fork behavior, and explicit access-program overrides with the feature disabled.
GitOrigin-RevId: ae96a4a8c7ab97c619716b9f39ea9f295df6e5a6
## Why
Reloaded subagent threads did not emit initialization analytics, and subagent initialization events always reported `new`.
## What changed
Emit initialization events for resumed spawned subagents before notifying thread listeners. Inherit parent client metadata before reserving a residency slot can evict the parent, preserve the thread's original `created_at`, and report `initialization_mode` as `resumed`. Refresh stored analytics metadata when a subagent resumes; newly created subagents continue to report `new`.
## Testing
Extend the cold-resume integration test to verify a single worker initialization event with the expected session, parent, source, resume mode, and original creation timestamp. Update serialization and session tests to check initialization modes.
GitOrigin-RevId: e78b0c4d88b6ddbe993ca7e1fe7717b6f74bf3d9
## Why
Updating a CRLF file with `apply_patch` previously normalized its line endings to LF unless preservation was explicitly enabled. Preserve the file's existing line endings without requiring an opt-in.
## What changed
- Use line-ending-preserving updates for both tool calls and standalone `apply_patch` invocations, removing the legacy normalization mode.
- Mark `apply_patch_preserve_line_endings` as removed.
- Always set `CODEX_APPLY_PATCH_PRESERVE_LINE_ENDINGS=1` in child environments for compatibility with older patch executables, overriding stale values.
## Testing
Update CLI, tool-call, shell-heredoc, and app-server tests to check CRLF preservation by default. Keep coverage for overriding stale compatibility environment values.
GitOrigin-RevId: 96d0b0e5350faa3fc7a45d63627a132657b44523
## Why
Removing a whole namespace previously listed both the namespace and every member as unavailable tools.
## What changed
Emit separate namespace and individual-tool sections in one removal notice for Responses Lite. A removed namespace subsumes its members, with instructions allowing tools declared in a later update to become available again. Keep individual removal notices for tools in surviving namespaces and for built-ins.
## Testing
Expand unit tests and snapshots to cover mixed removals, empty catalogs, restoration, and replacing a namespace with a built-in of the same name. Extend the MCP refresh scenario to verify namespace removal and restoration, successful calls after restoration, preserved request history, and no repeated updates on unchanged turns.
GitOrigin-RevId: 66aa43a41db956cb5458121ea1db8c673a7ce948
## What changed
Update `.bazelversion` from 9.0.0 to 9.2.0 and refresh
`MODULE.bazel.lock`, including lockfile format version 28, registry hashes,
module extension digests, and cached crate metadata.
GitOrigin-RevId: 52689e818bf0eb37d9339df8d8a09c6cbe43e4d8
## Why
Release builds for different tags can run concurrently, but publication must remain serialized so channel checks and updates cannot race or move release pointers backward.
## What changed
Scope workflow concurrency to `${{ github.workflow }}-${{ github.ref }}`. Keep `release`, `publish-r2`, `publish-npm`, `winget`, and `update-branch` on a shared `rust-release` concurrency group with `queue: max` and `cancel-in-progress: false`.
GitOrigin-RevId: 75b42fd765db6091fb9190aae2ecccd2bb959d08
## What changed
Support `browser_use.extension.request_headers` as a list of `name`/`value` pairs and expose it through `config/requirements/read` as `browserUse.extension.requestHeaders`. Update the generated JSON schemas, TypeScript types, and Python models.
Preserve header values, including template strings, verbatim. Higher-priority requirement layers replace the entire header list, including with an explicit empty list. Redact header values in Rust debug output while retaining them in API serialization.
## Testing
Add coverage for parsing and malformed entries, extension scoping, empty-list overrides, API mapping and read responses, and debug redaction without changing serialized values.
GitOrigin-RevId: 02299e82a91aa863966d0277091bc5e8cc1ebe07
Extend the app-server thread metadata test to archive a thread after pinning
and unpinning it, before any turn starts. Assert that the thread appears in
`thread/list` results with `archived: true` and `use_state_db_only: true`.
GitOrigin-RevId: dde58e892b28843870bc3f678134fc86b93cd79c
## What changed
Install a temporary `SIGCONT` handler and unblock the signal during `Ctrl+Z` suspension. After sending `SIGTSTP`, wait for the handler to confirm resumption, returning a timeout error if no confirmation arrives within the bounded wait.
Restore the previous signal handler and thread signal mask, resume terminal stderr handling, and reapply terminal modes even when suspension fails. Propagate signal setup, delivery, and restoration errors to the caller.
GitOrigin-RevId: 1a7e10e982b1f6b2c7c7d75362a01989409b3b4d
## Why
Unix control-socket shutdown removes the socket and rendezvous link but leaves the startup lock file behind.
## What changed
Keep a removable startup lock with the control-socket guard and release the lock after publishing the rendezvous link. On cleanup, reacquire the lock and verify that the path still identifies the same file before removing it.
Use nonblocking acquisition with asynchronous retries, checking file identity after acquisition to handle lock-file replacement.
## Testing
Add tests for nonblocking lock contention and dangling symlink rejection, and extend the control-socket lifecycle test to verify that the lock file is removed on shutdown.
GitOrigin-RevId: 469ed5269f32ae1c0655d40d28519ef5e94ba6be
## What changed
- Record nonempty base instructions as a developer message after tool declarations at the start of each incremental tool context window, and omit the request-level `instructions` field.
- Preserve this prefix when rebuilding history after local or remote compaction, while keeping the compaction summary last.
- Count recorded base instructions once when estimating context usage and trimming tool outputs.
## Testing
Add regression coverage for instruction placement, omission of request-level instructions, compaction ordering, and token accounting. Exercise remote compaction trimming with both request-level and recorded base instructions.
GitOrigin-RevId: 6a6fda92c5c6eb33852a77b38d34c028cf78b164
## Why
Publishing an older stable version should not replace a newer release as the default download or installation target.
## What changed
- Compare stable versions before marking a GitHub release as latest, allowing same-version reruns to finish publication.
- Guard npm `latest` and platform dist-tags, publishing older versions under separate `release-<version>-<tag>` tags.
- Check R2's `latest` channel before updating it or the installer aliases, while allowing same-version reruns to repair interrupted installer updates.
- Reject invalid existing stable release metadata and consolidate GitHub latest and canary checks in `releases.py`.
## Testing
Add regression tests for stable version ordering, same-version reruns, npm package and platform tags, and invalid channel metadata. All 21 tests in `.github/scripts/test_releases.py` pass.
GitOrigin-RevId: e6bad3ee163b279ac1661b9070712a41eedd50ff
## Why
Transient admission errors or connection resets can prevent a code-mode session from opening before any execution starts.
## What changed
- Retry `OpenSession` and the initial lease message on `Unavailable` or `ResourceExhausted`, with at most three attempts and 100 ms and 200 ms delays within a single startup deadline.
- Classify HTTP connection and request failures as `Unavailable` so admission can recover from connection resets, while preserving error sources.
- Keep retries limited to initial admission so established executions are never replayed.
## Testing
Add gRPC integration tests covering transient status recovery, the retry limit, immediate failure for non-retryable statuses, and successful session execution after a connection reset.
GitOrigin-RevId: 3b654bcd377a5addf7c3ed58bb1c72a449b2f7f7
## Why
Thread-owned Guardian context is always enabled, and `guardianv2.thread_context` is deprecated and ignored.
## What changed
Remove explicit `GuardianThreadContext` enables from retained-context and heartbeat tests. Parameterize the heartbeat skill-context test with optional feature lists so it covers the default behavior and `GuardianRootHandoffContext`, each with one or three heartbeats.
GitOrigin-RevId: 78e3159832bff08b79c7977d876d9acb587e9c71
## What changed
Extend the Windows signing action with an `additional-files` input and sign `scripts/install/install.ps1` with Azure Trusted Signing in the x64 release job. Stage the architecture-independent installer after compression so it remains a plain script, and publish the signed artifact as `install.ps1` instead of copying the unsigned source.
## Testing
The Windows release workflow verifies that the installer has a valid Authenticode signature and a timestamp certificate before staging it, failing the job if either check fails.
GitOrigin-RevId: 6f16a084b8f350fbf3644c36d75651a6f4b88506
## What changed
- Accept per-environment `skills.required` lists through `environment/add` and `environments.toml`.
- Before inference, require each named skill to be enabled and supplied by the selected environment. Missing skills fail the turn before a model request, including when environment setup fails.
- Stop applying an environment's requirements after it is deselected. Exempt isolated Guardian reviewers, which have no skill catalog.
## Testing
Add tests for available, missing, disabled, and wrong-environment skills, failed environment setup, recovery after deselection, and propagation of TOML requirements to the correct environment.
GitOrigin-RevId: 302ced4774697d2f414f745fe0535e71f747eda2
## What changed
Move base instructions from the top-level `instructions` field into a prefixed `developer` message in `input` for standard Responses requests, matching Responses Lite. Remove the field from HTTP and WebSocket request types and assign instruction messages stable IDs derived from the thread and instruction text.
## Testing
Extend standard and Responses Lite tests to cover instruction message serialization, stable IDs, and resume consistency. Update WebSocket tests to verify that changed instructions trigger a full request without `previous_response_id`.
GitOrigin-RevId: e2de4b8e30a9339377fac133ceda981abd1a112b
## What changed
Give the initial Guardian review and its checkpoint recovery attempt separate recovery flags instead of resetting a shared flag. Keep the single restart under the original review deadline.
Represent reviewer selection explicitly with `ReuseIfAvailable` and `FreshParentCheckpoint`, so recovery requires a fresh session and ignores reusable fork snapshots.
GitOrigin-RevId: 35f63f375e2a8bef10271944e222ffce1d1939c4
## Why
A Guardian review restarting from the parent checkpoint must bypass cached reviewer sessions and snapshots, even when another review is using the cached session.
## What changed
- Add `ReviewerRequest::requires_fresh_session` and enable it for parent-checkpoint recovery.
- Replace an idle cached session with a fresh reusable session, or start a fresh ephemeral session when the cached session is busy. Neither recovery path inherits a cached snapshot.
- Reserve the review permit before validating a cached session and before exposing a newly spawned session to concurrent requests.
## Testing
Add tests covering recovery with idle and busy cached sessions, verifying that recovery receives no cached snapshot and that subsequent reviews reuse the appropriate session.
GitOrigin-RevId: 894f685736da54312336932aa2037e74a20629d9
## Why
Reviewer compaction can invalidate previously admitted transcript evidence. When a parent checkpoint is available, restarting from that checkpoint preserves the captured parent context instead of relying on a lossy reviewer summary.
## What changed
- Restart an invalidated reviewer once from the action-time parent checkpoint, within the original review deadline.
- Preserve fresh checkpoints during startup and fit review input using the existing budget selection.
- Select transcript evidence from the checkpoint actually loaded by the reviewer. Track the transcript source so cursors remain valid across legacy-history eviction and reset when the source changes.
- Resume transcript deltas after successful recovery, including authorization added after the parent checkpoint.
## Testing
Add regression coverage for checkpoint recovery, post-checkpoint authorization, resumed deltas, and stopping after one restart. Extend history tests to cover both legacy retention and parent-checkpoint reuse, and update the checkpoint-migration snapshot.
GitOrigin-RevId: bc20fb9489afaad963303beff1c79f62fa5023f7
## What changed
Use `OPENAI_API_KEY` for the Guardian Decisions sampler when `CODEX_GUARDIAN_DECISIONS_API_KEY` is absent, the provider is `openai`, and no custom base URL is configured. Preserve dedicated-key precedence, including empty values, and do not fall back for other providers or custom base URLs.
## Testing
Add a credential-selection test covering fallback, dedicated-key precedence, empty dedicated keys, and provider and base URL restrictions.
GitOrigin-RevId: a2a62c28789597f013544b51e142b21f9e214080
## What changed
Expose two JavaScript globals for consuming results as inputs settle:
- `as_settled(promises)` returns an async iterator of fulfilled and rejected records in settlement order, preserving queued results while the consumer is busy.
- `stream_settled(promises, emit)` delivers those records to a callback, awaiting each invocation and propagating callback errors.
Records include an `index`, a `status`, and either a `value` or a `reason`. Iterable inputs use positional indices; `Map` inputs retain their keys. Both helpers accept promises, thenables, and plain values.
## Testing
Add runtime coverage for ordering, input types, object identity, callback behavior, early iteration exit, and termination. Add stdio and gRPC host tests for partial results across waits, plus a scenario snapshot verifying fulfilled and rejected records reach the model.
GitOrigin-RevId: cddc9f3679ae04f2421e154caa0417afb15f550d
## Why
Incremental namespace declarations contain only changed or added tools. Their descriptions need to make clear that previously declared tools remain available unless explicitly marked unavailable, and that redefinitions replace earlier definitions.
## What changed
Append this guidance to updates of existing namespaces, preserving any namespace description. Leave initial declarations and catalog hashes unchanged.
## Testing
Extend unit and request-history coverage for the namespace hint, unchanged turns that append no tool definitions, and MCP tool removals that append a standalone notice without rewriting history or repeating the notice on the next turn.
GitOrigin-RevId: e32f3c9948efb44a1253868fe67967f117cc21e8
## Why
Manual, pre-turn, and post-turn compaction previously deferred rebuilding initial context until the next turn. Their saved replacement history could omit refreshed instructions and skill catalogs.
## What changed
- Install initial context during local and remote compaction, before the last real user message or summary, keeping the compaction summary last.
- Persist matching full world-state and turn-context baselines with every replacement instead of retaining only partial extension metadata.
- Build replacement context and recompute token usage for the current model even when the previous model performs compaction. Reuse that captured context for eligible current-model retries.
- Capture manual compaction context centrally and propagate preparation errors to the task runner.
## Testing
Update assertions and snapshots for context ordering, refreshed instructions, resume and fork history, current-model checkpoint baselines, and cloud skill catalog retention across compaction and resume.
GitOrigin-RevId: 8572a76c31c6884a3c580b3bbb350d49af876bd1
## Why
The Decisions adapter rejected developer messages, including host-annotated trusted-tool context. Requests containing that context could not be classified.
## What changed
Append developer text annotated with `TrustedTool::KIND` to the classification rubric, preserving its authority while keeping user evidence in the input messages. Accept only a single text part with a single matching annotation; continue rejecting other developer messages and unsupported evidence.
## Testing
Add a regression test covering trusted-tool context alongside untrusted user text, plus rejection of incorrect roles, missing or mismatched annotations, multiple annotations or content parts, and image content.
GitOrigin-RevId: 65b6301b2ee1ac54d67275978ccb5e37dcac7c16
## Why
MCP elicitation reviews used turn-start context, which could omit remote environments that became ready before the tool invocation and use stale environment permissions.
## What changed
Capture the issuing step's Guardian review context with each live MCP invocation and reuse it for elicitation reviews. Fall back to turn context when no matching live invocation is available, and preserve the captured context for in-flight actions.
## Testing
Extend the deferred-executor regression test to cover MCP elicitations, checking that Guardian receives the newly ready remote environment and its denied paths, excludes stale local denied paths, and returns the denial to the parent model.
GitOrigin-RevId: 0cc58b8f30543a9af87d53e1a90f574a8e6a2f84
## What changed
Measure `responses_duration` directly around `sampler.sample()` in the snapshot classification path. Leave it unset for conversation classification instead of timing submission and waiting for the score.
GitOrigin-RevId: 4cfac9db6f19f3c8513d7bf839ea9631d41bf3ac
## Why
Aborting a refresh task cannot retract a response already queued for delivery. The test helper could consume that stale response and return before the replacement refresh completed.
## What changed
Make `finish_overview_refresh` skip responses whose request ID does not match the active refresh. Extend the lifecycle test to queue an invalidated response before removing a task, exercising the wait for the replacement refresh.
GitOrigin-RevId: 97341681682e8dce9a9512fbcc1d5c0351b084f5
## Why
An already-cancelled delegate spawn can report a runtime admission or startup error instead of `TurnAborted`, including when runtime shutdown has been requested.
## What changed
Check the cancellation token before runtime admission and session startup so prior cancellation returns `TurnAborted` immediately after approval-policy validation.
## Testing
Extend the pre-cancelled spawn test to cover both normal operation and requested runtime shutdown, asserting `TurnAborted` within a one-second timeout.
GitOrigin-RevId: 5a25a211acdd5c246a3c638243ccc8b7240fd051
## Why
Snapshot classifier requests can arrive out of order, so continuation tests need to keep the next tool blocked until the current tool's classifier request has been captured and checked.
## What changed
Gate every mock Guardian review in high-risk review continuation scenarios. Release each review after checking the corresponding classifier request, preserving the ordering needed by the existing assertions.
GitOrigin-RevId: 9e52acd2bb1ce2fb71100fe0e1b92304d29e9634
## Why
The warning assertions need tracing callsite interest to remain independent of untraced parallel tests, even when the test runner already owns the global subscriber.
## What changed
Run the test on a current-thread Tokio runtime and capture warnings with a thread-local subscriber and an explicit buffer. Keep a `NoSubscriber` dispatch alive to stabilize callsite interest, and assert the deferral warning and `client_echo` directly against the captured logs.
GitOrigin-RevId: 5bf22b2cbfefcf8f65016d2cc1444112d9f6a6c7
## What changed
Add `tools_change_count` to turn profiles and turn analytics events. Compare the full model-visible tool list before each sampling request, retaining the previous list across turns and connection resets. The first list establishes a baseline; subsequent changes increment the current turn's count.
## Testing
Add coverage for schema changes, tool additions, ordering changes, empty lists, and tracking across sessions and transport fallback. Extend the turn event serialization test to include `tools_change_count`.
GitOrigin-RevId: 44a15c42dc7d0b35c166666faeb9627b718b33dd
## What changed
Add the default-off `stable_environment_tools` feature flag. When enabled, advertise environment-backed tools before an executor is ready, keep environment selectors stable as readiness changes, and include the `shell` and `login` parameters. Execution still requires a usable environment and its policy.
When disabled, expose environment-backed tools only when a usable environment exists, derive selectors from usable environments, and condition shell parameters on the execution configuration. Restore tool-specific unavailable-environment errors and skip the environment readiness check for `write_stdin`.
## Testing
Parameterize the empty-environment tool availability test for both flag states, check that commands require a ready transport by default, and explicitly opt tests that rely on stable tool exposure into the feature.
GitOrigin-RevId: 68c6240fb3adf85d7f9b407804d4823c515abfdc
## Why
Malformed `deny_read_acl_state.json` previously caused deny-read ACL reconciliation to fail. Recovery must restore bookkeeping without removing unknown existing restrictions or modifying a linked file's contents.
## What changed
- Retry malformed reads for up to two seconds, then rebuild bookkeeping only after excluding active writers and successfully applying current deny-read ACLs. Preserve unknown historical denies and continue propagating I/O errors.
- Validate the opened state file before reading or writing, rejecting reparse points and files with multiple hard links.
- Write state in place without truncating before validation, preserving file identity and permissions. Retry sharing violations during writes while preventing replacement through delete access.
## Testing
Add Windows tests for corrupt-state recovery, linked-file rejection, concurrent writer and delete-handle behavior, file identity and ACL preservation, and subsequent permission-profile changes. Extend the elevated sandbox integration test to verify that denied reads remain blocked after recovery while allowed writes and deletes succeed.
GitOrigin-RevId: 4aca32df00d015df3763fdc447ffdfbe3fd6cec0
## Why
Fresh starts connected to an app server can bootstrap with stale client model settings before reading the server configuration. An empty model catalog can also prevent startup even when managed new-thread defaults provide a model.
## What changed
- Read server configuration before model bootstrap for fresh starts using a local daemon or remote server without an explicit profile.
- Preserve explicit model and reasoning-effort overrides, clear implicit client settings when `config/read` is unsupported, and allow managed new-thread defaults to supply a model when the catalog is empty.
- Use the launch directory for local daemon configuration reads and the server directory for remote reads.
## Testing
Update startup-default tests to cover managed model selection with an empty catalog. Strengthen the reconnect test with a stale client model and an assertion that `config/read` uses the server directory.
GitOrigin-RevId: 8fe1485c6e66c8d46560b34d904ce1724458993a
## Why
New embedded TUI threads forced reasoning summaries off when no summary was explicitly configured, overriding the model's default. Client settings could also override the destination server's reasoning summary configuration.
## What changed
Use the same launch override handling for embedded and remote thread starts so server configuration and model defaults determine reasoning summaries. Forward explicit profile and command-line choices for `model_reasoning_summary` and `features.concurrent_reasoning_summaries`, preserving both enabled and disabled values.
## Testing
Extend coverage for model defaults reaching Responses requests, concurrent summary delivery, direct startup, and replacement sessions with profile and command-line overrides.
GitOrigin-RevId: c60e33d077298d7a89d6b95f94b1292c175d6c77
## What changed
- Remove redundant snapshot fixtures and selected rendering test cases across the TUI.
- Replace several full-output snapshots with direct assertions on messages, popup state, status indicators, and rendered content.
- Consolidate slash-command aliases, command-prefix selection, category titles, and hook events into shared test loops.
- Use shared snapshots for the setup import prompt and paginated transcript overlay across platforms.
GitOrigin-RevId: 461e30ebaf70ba930d91a135d2fc598ee4f04f27
## Why
A review can fail before the UI receives the event that enters review mode. Failed-turn completion also needs to preserve the running indicator when a queued `/review` has already been submitted and is awaiting startup.
## What changed
- Emit the review-entry lifecycle before starting the review task, after aborting existing tasks and clearing connector selection.
- When a live failed-turn completion repeats an already handled error, refresh task state only if no user turn is pending startup, and continue processing queued input.
## Testing
Add regression tests for lifecycle ordering on a server-overload response and for preserving the running indicator while a queued review awaits startup after a failed turn.
GitOrigin-RevId: 0f91d3d1a1a983542c54c2686630de9c232321b1
## What changed
Make plain `codex remote-control` start or reuse the managed daemon and enable remote control when daemon auto-start is enabled and the environment is eligible. Fall back to the foreground server when no managed backend is available or Windows restricts detached launch.
Add `codex remote-control --no-daemon` to explicitly run the foreground server, and honor the top-level `--no-daemon` flag. Reject this flag with `start`, `stop`, or `pair`. Keep `--json` and launches with configuration overrides or unsupported environments on the foreground path.
GitOrigin-RevId: cb28ae3f6074993b748660972c3cb7cbf6612c2f
## Why
Some Windows policies deny in-process reparse-point mutation while allowing the system junction creator, preventing managed daemon release selection.
## What changed
Fall back to `cmd.exe` with `mklink /J` when native junction creation or retargeting returns `PermissionDenied`. Pass quoted paths through environment variables and disable delayed expansion to handle shell metacharacters.
Create the replacement junction before moving the existing `current` junction aside, and attempt to restore the previous junction if installation fails. Preserve it for recovery if restoration also fails.
## Testing
Extend the Windows junction test to cover fallback creation, native retargeting, and fallback replacement under a path containing spaces, `&`, `%`, and `!`, while verifying that no standalone CLI installation is created.
GitOrigin-RevId: 039ee850f8c788f44f08116614ca3927e3e9952f
## Why
Pressing `/` in Vim Normal mode starts a composer search, even when the draft is empty. Allow this key to open slash commands directly on an empty draft.
## What changed
When slash commands are enabled, a standalone `/` on an empty draft switches to Insert mode, inserts `/`, and opens command completion. Preserve Vim search behavior for nonempty drafts, `?`, and pending operators.
## Testing
Add a snapshot test for the Insert mode transition and command picker. Exercise Vim slash-command entry in the transcript overlay test across terminal sizes, and extend command sparkle coverage to Vim mode.
GitOrigin-RevId: 806c2f6b841190ccdc1a258f88dfa590773ba33a
## Why
Command Center previously reset to project grouping on startup, losing the user's selected grouping.
## What changed
Save grouping changes to `tui.agents_overview_grouping` in the client’s user configuration and restore the saved choice at startup. Support `project`, `status`, and `model`, with `project` as the default. Report save failures in Command Center while keeping the selected grouping active.
## Testing
Add tests for cycling through and persisting all grouping modes, preserving unrelated settings in a custom configuration file, displaying save errors, and restoring saved grouping during startup.

## Why
Executable scanners can briefly hold newly staged files without delete sharing, causing the rename that publishes a managed daemon release to fail on Windows.
## What changed
Retry publication on permission-denied or sharing-violation errors at 50 ms intervals, up to 100 retries. Report the staging and release paths if publication fails.
## Testing
Add a Windows test that holds the staging directory open without delete sharing, releases the handle after a delay, and verifies that publication succeeds with the payload intact.

## Why
MCP startup notifications from unrelated threads could create TUI event channels, allowing subsequent approval requests from those threads to appear in the current session.
## What changed
Check the parent of an untracked subagent before accepting its MCP startup notifications. Read thread metadata with bounded retries for threads that are not yet found or loaded, and ignore notifications unless the parent belongs to the TUI.
Share thread ownership checks across notification and approval routing, including side threads.
## Testing
Extend approval-routing coverage to verify that owned subagent approvals are preserved both before thread-start notifications and after MCP startup notifications, while unrelated threads do not create event channels or display approval prompts.

## Why
`/archive` was disabled during a running turn, preventing users from archiving the current session until the turn ended.
## What changed
Enable `/archive` during a running turn and warn in the confirmation dialog that archiving will stop the current turn. Cancelling the dialog leaves the turn running.
## Testing
Extend confirmation tests to cover both idle and running sessions, add a snapshot of the running-turn warning, and verify that cancellation leaves the task running without emitting archive events or operations.
