## Why
Forked subagent startup serializes history persistence and spawn-edge writes. Cancellation during startup can also leave a provisional child behind.
## What changed
- Defer copied-history durability so it can run alongside spawn-edge persistence, while still awaiting both before submitting the child's initial input.
- Commit agent and residency reservations and notify clients only after initial input is accepted.
- Guard provisional children so cancellation or startup failure removes and shuts them down, discards their stored state, and closes their spawn edge after any pending edge write finishes.
## Testing
Add coverage for cancellation at the child-history durability barrier, checking child termination, removal, and edge closure. Extend fork-context tests in legacy and paginated history modes to verify inherited context can be read from storage after spawn acknowledgment without flushing the live child first.

## What changed
Add `openai.gpt-6-sol` and `openai.gpt-6-luna` to the Bedrock catalog, including `global.` and `us.` variants for Bedrock Runtime. Make GPT-6 Sol the default and provider fallback model, preferring its global variant for Runtime. Retain the existing models and update model picker ordering.
## Testing
Extend catalog and provider tests to cover the new models, metadata, ordering, and default selection. Update thread-start tests for supported model preservation and fallback behavior, and refresh Mantle and Runtime model picker snapshots.
GitOrigin-RevId: 5ce646e384353ae26cdfc4ea4e7c049ac61e698c
## What changed
Skip the thread store title lookup when initializing an ephemeral fork, leaving its thread name unset.
## Testing
Add a regression test that forks an ephemeral thread from history and verifies that the in-memory thread store's `read_thread` count does not increase.
GitOrigin-RevId: 81180c4a836c932584d2cb94c0816eae33b04af3
## Why
Callers need to interrupt a specific active turn without discarding queued input. Tool callbacks must be able to await the interruption decision without blocking task cancellation.
## What changed
- Add `CodexThread::interrupt_if_no_pending_input` and `Op::InterruptIfNoPendingInput`.
- Check the turn identity and pending user input or mailbox items before taking the active task. Leave the turn running for stale or abandoned requests.
- Acknowledge the decision before joining cancellation, and unblock pending submissions when the active task is cancelled.
## Testing
Add regression coverage for successful interruption, stale turns, preservation of queued user input and agent mail, abandoned requests, and cancellation while the submission queue is full.
GitOrigin-RevId: 42e31c09369fb070ba1b4b3c64ef45334dd872d8
## What changed
- Add “Inspect activity” to the shortcut help’s Session section, using the runtime `focus_activity` binding (`F4` by default) and hiding it when unbound.
- Remove the passive activity footer hint so composer hints remain available. Keep previous, next, details, and back controls while activity is focused, shortening them to fit the available width.
## Testing
Add snapshot coverage for default, remapped, and disabled activity shortcuts. Update footer coverage to verify the absence of passive hints and interactive controls at 20, 32, and 80 columns.
GitOrigin-RevId: 52ca6f4992778cd3cf3eebe163d533e69a8dabeb
## What changed
- Add `gpt-6-sol` and `gpt-6-luna` catalog entries and refresh model descriptions.
- Offer migrations from `gpt-5.5`, `gpt-5.6-sol`, and `gpt-5.6-terra` to `gpt-6-sol`, and from `gpt-5.6-luna` to `gpt-6-luna`.
- Retarget retired `gpt-5.4` and `gpt-5.4-mini` selections to GPT-6 Sol and Luna, respectively.
- Recommend `gpt-6-luna` in the rate-limit switch prompt.
## Testing
Extend migration tests to cover the new targets, their default reasoning effort, and prompting again after a previously acknowledged migration to an older target. Update model-picker and rate-limit prompt snapshots.
GitOrigin-RevId: d3a093d18ce44a903383504ab8f5cbbc911d602d
## Why
An empty composer hint row already separates activity from the input. Adding another separator wastes transcript space, especially in short terminals.
## What changed
Reserve the extra separator only when copy status text, a follow control, or a fitting hint occupies the shared row and the viewport has room. Recalculate the transcript layout in the same frame when adding that separator, and use a shared timestamp for copy status visibility and expiry.
## Testing
Extend snapshots for running turns with no hint, follow controls in short terminals, and copy status text at narrow widths and limited heights. Update resize assertions to check that the draft and caret remain stable relative to the terminal bottom.
GitOrigin-RevId: a73894063b759ec6b9a25f720e0e8007516109c8
## Why
The generic state integrity failure message does not identify which database needs attention.
## What changed
- Include the paths of all databases that fail integrity checks in a structured issue, shown in text summaries and JSON output, with the existing recovery guidance.
- Redact sensitive details using `: ` as the field-label separator so Windows drive letters are not mistaken for labels and unlabeled sensitive paths are fully redacted.
## Testing
Add coverage for single and multiple failed databases, summary and detailed text output, JSON output, preservation of damaged database contents, and sensitive path redaction on Unix and Windows.
GitOrigin-RevId: ac5fec9473d22b6b137a9fc8a751aba8605d940f
## What changed
Remove trailing periods from concise built-in option descriptions and disabled-option explanations, and simplify wording across TUI menus. Share the built-in permission preset descriptions between permission pickers.
Document the convention in `codex-rs/tui/styles.md`, including normal punctuation for descriptions with multiple sentences and preservation of externally supplied descriptions.
## Testing
Update menu assertions and rendering snapshots for the revised copy and line wrapping.
GitOrigin-RevId: 3231d25484178452ab001af5ddc982460d14f94a
## Why
Failed image requests discarded the `x-codex-imagegen-request-id` header, leaving failure analytics without the request ID.
## What changed
Carry the request ID through `ImageRequestError` and backend errors for image generation and editing. Preserve it on failed image generation items for HTTP errors, response decoding errors, and responses with no image data.
## Testing
Extend the app-server failure test to verify that a request ID returned with an HTTP 500 response reaches `codex_image_generation_event` analytics.
GitOrigin-RevId: 57cddacc0221e5b58877ac375d5eca0afb99d853
## What changed
Reject authorization endpoints with schemes other than `http` or `https` before client registration or authorization URL return. Document this constraint for `mcpServer/oauth/login`.
## Testing
Make existing asynchronous tests wait for cleanup: wait for `ThreadIdle` before injecting user input in the guardian cached-score test, and poll for queue consumption before asserting that dispatched items are gone.
GitOrigin-RevId: e5f6b4c5556234c3cc2aa56910486e892c011116
## Why
Sentry tags cannot contain newlines or exceed 200 characters, but report comments can contain both.
## What changed
Limit the `reason` tag to the first 200 Unicode characters and replace each carriage return or newline with a space. Preserve the full, unchanged comment in the exception body.
## Testing
Add coverage for line endings, the 200-character boundary, and multibyte Unicode comments. A mock upload test checks that the compressed Sentry envelope contains the bounded tag preview and full comment, even when caller tags attempt to override `reason`.
GitOrigin-RevId: e0f0db6a9797a817da2f868727077c948ad82bfb
## Why
Compaction companion records do not represent all resume state, including the last started turn and previous turn settings. The selected multi-agent runtime also needs a persisted value when no companion turn context is present.
## What changed
- Add optional `resume_metadata` to `CompactedItem`, recording the multi-agent version, last started turn ID, and previous turn settings. Preserve the distinction between absent metadata and explicitly empty values while retaining compatibility with older records.
- Capture this metadata under the settings persistence lock alongside the compaction checkpoint.
- Rewrite inherited metadata to use the child agent's runtime, and clear previous turn settings when the child must rebuild context.
- Clear pending continuation state before delivering acceptance of standalone settings updates, while holding the persistence lock.
## Testing
Add coverage for metadata round trips with empty values, legacy reader compatibility, checkpoint companion records, inherited fork metadata, and continuation invalidation while settings event delivery is blocked.
GitOrigin-RevId: f30b7feaa7e2fdb5b65fc3c53b37fd7a7fe27903
## What changed
Render unordered bullets as `•` and task markers as `☐` or `☑`, preserving ordered numbering and continuation indentation in streaming and completed Markdown. Add `tui.rendering.lists`, enabled by default; setting it to `false` retains hyphen bullets and textual task markers.
## Testing
Add snapshot coverage for nested, ordered, quoted, and wrapped task lists, plus code and escaped markers. Add character-by-character streaming tests that compare incremental and emitted output with full rendering, with list rendering enabled and disabled.
GitOrigin-RevId: df9209d8c42f277dd2a2d7073ea19a6feb7dd706
## Why
Several TUI views hard-code 24-hour timestamps even when the detected system preference is 12-hour time.
## What changed
Use the existing `ClockFormat` preference for rate-limit and spend-control reset times, usage notices, backend banners, reset-credit expiration times, analytics timestamps, and expanded session details in the resume picker. Capture the preference when constructing views and preserve existing timezone handling, including analytics' UTC labels.
## Testing
Add coverage for midnight, noon, and next-day reset labels in both clock formats, plus 12-hour analytics rendering with UTC labels. Update snapshots for status, banners, usage notices, reset-credit details, and expanded sessions, including narrow-width layouts. Pin test fixtures to explicit clock formats for deterministic output.
GitOrigin-RevId: 73c36d603ddc4eb7800614650a14c6f2961f8b70
## Why
In read-only sessions with an external writer, `Esc` could enter prompt backtracking or be consumed by a scrolled transcript instead of returning to the agent command center.
## What changed
- Exclude external-writer views from prompt backtracking and let `Esc` navigate away from scrolled transcripts. Active search and selection still consume `Esc` first.
- Close the legacy transcript overlay without starting a backtrack preview or changing the retained draft.
- Allow `Esc` to open the agent command center while disconnected, showing a stale-list notice with reconnect status instead of requesting a refresh.
## Testing
Add regression coverage for normal, scrolled, detailed, and offline read-only views, command-center snapshots, and retained-draft preservation when closing the legacy transcript overlay.
GitOrigin-RevId: e2623d25dd4b4beea13b6f517932280168113dce
## Why
Status symbols in the agents overview retained their status color when selected, making their styling inconsistent with the rest of the selected row.
## What changed
Apply the row's selection style to its status symbol while preserving status colors for unselected rows.
## Testing
Extend rendering tests to assert and snapshot selected status symbol styles across status variants, and verify that an unselected idle symbol retains its cyan color.
GitOrigin-RevId: a5163841bed80d6d43e7c62a7596c6e48b9dc886
## Why
Automatic daemon launches could silently fall back to embedded mode when shared feature settings differed from the session's requirements. Changing those settings affects other clients, and restarting the server may interrupt active or queued work.
## What changed
- Offer interactive choices to run without the daemon, restart with the required settings, or cancel. Default to cancel and require explicit confirmation for restart.
- Allow restart only for managed daemons with a feature mismatch, then recheck compatibility once. Noninteractive required-daemon failures return an error with `--no-daemon` guidance; optional attachment retains its fallback behavior.
- Preserve saved feature overrides on startup and require confirmation before applying requested shared-feature disables, including on fresh starts.
- Merge confirmed settings under the lifecycle lock, persist changes after the old process stops, and avoid restarting when the saved overrides already match.
## Testing
Add recovery-menu snapshots and confirmation tests, compatibility tests for required and optional attachment, daemon ownership and settings-preservation tests, and CLI terminal tests for cancellation, embedded fallback, confirmed restart, and disabling shared features.
GitOrigin-RevId: d50a6cf7e476b9647237431e8fc0fc6041ed17db
## Why
`/import` was unavailable in remote sessions and when connected to the local app-server daemon. Shared servers also broadcast import completions from other clients, which must not clear this client's pending import or report its completion.
## What changed
- Allow external setup migration through the connected app server in both session types.
- Detect setup using the active thread's working directory, or the remote working-directory override before a thread starts. Use home-only detection when no remote directory is available.
- Track the returned `import_id` and only clear the pending import and report completion for a matching notification.
- Skip refreshing configuration from local disk after import completion in remote workspaces.
## Testing
Add shared-transport coverage in embedded and remote modes for detection with and without a working directory, retrying failed imports, rejecting overlapping imports, and matching interleaved completion notifications queued before the import response.
GitOrigin-RevId: 864ed9fe87e5c554da79907ed80a01f0c9948392
## Why
Guardian prompts are synthetic review context, but legacy thread metadata can duplicate them in titles, previews, and first messages. Keep SQLite metadata small while retaining rollout JSONL as the canonical record.
## What changed
Add a migration for Guardian threads that:
- Replaces blank or prompt-derived titles with `Guardian review`.
- Preserves nonblank names and distinct nonblank titles, using the title as the name when no name exists.
- Sets `preview` to `Approval review` and clears `first_user_message`.
## Testing
Add a migration test covering prompt-derived and blank titles, custom titles and names, and unchanged metadata for a non-Guardian worker thread.
GitOrigin-RevId: 65b5ff5200a39a19fb11f494de6dca7710ff6cc6
## Why
Guardian review threads use synthetic approval prompts as user messages. Deriving thread titles and previews from those prompts exposes large, unhelpful summaries in thread listings.
## What changed
- Default Guardian threads to the title "Guardian review" and preview "Approval review" across metadata creation, rollout reads, and resume.
- Skip synthetic user messages and goal updates when deriving Guardian display metadata, leaving `first_user_message` unset for new threads.
- Preserve custom names, including legacy indexed names, when listing, reading, resuming, and migrating threads to paginated history.
## Testing
Add regression coverage for compact metadata, resume without session metadata, custom names before and after migration, and app-server persistence, listing, and rename/resume behavior.
GitOrigin-RevId: 42aa707db20c3e57ffa5fd4c91ee313710be10d7
## What changed
Extract `LocalAgentRuntime` from `LocalAgentControl` to hold the shared registry, residency state, execution limiter, rollout budget, service tier, instruction provider, and thread-manager bindings. Keep session identity on the controller handle.
Store the runtime in `SessionServices` and use it to bind controllers for child startup, resume, delegation, and guardian reviews. Route ownership checks and residency handling through the shared runtime, preserving registry identity across handles. Update existing test fixtures to keep the controller and runtime paired.
GitOrigin-RevId: 846094657cbdf736da3149f0a1c96b4e01423dfe
## What changed
Move `spawn`, `send`, and `inspect` into the `AgentControl` implementation for `LocalAgentControl`, removing the forwarding methods and the `spawn_request` module. Update tool handlers and existing tests to use the trait methods, and remove redundant boxing at spawn call sites.
Preserve spawn validation, message attribution, runtime loading, and queue-only delivery semantics.
GitOrigin-RevId: 6027d4d97d0dfb6763dc97ef92a2d7ef58de945d
## What changed
Update `extra_policy_reaches_guardian_review` to expect a retained user
instructions section before the transcript, including the source-order notice
and the original user request. Adjust the subsequent snapshot item numbers.
GitOrigin-RevId: 9e57f9bb7cdc9318787d083bf4350143a1353287
Verify that unsubscribing from a message board thread remains effective
after posting to that thread and resuming the session. The runtime test
checks that replies from a child agent produce no `CHANNEL_POST` notices
while unsubscribed and that explicit resubscription restores delivery.
Use gated streaming responses to keep the recipient active during each
reply and drain worker completion messages before checking notices.
GitOrigin-RevId: fe2695a46722a94e6fca86a3d3bd49c0b8bb7ee7
## What changed
Mark `guardianv2.thread_context` as stable and enable it by default for synchronous and asynchronous Guardian reviews. Keep it independent of the Guardian v2 `enabled` toggle and preserve explicit configuration and profile overrides. Update the configuration schema documentation to match.
## Testing
Update coverage for default configuration and sender user messages, review prompt snapshots, history retention across compaction, and checkpoint provenance. Assert that later user input invalidates an in-flight review's authorization. Keep legacy transcript budgeting coverage by explicitly disabling thread context in that test.
GitOrigin-RevId: 19afd34d7bfc0ee36bbf878089c68b732a21bc6a
## Why
Thread-owned Guardian review rejected usable parent compaction checkpoints when the reviewer's `comp_hash` differed or was unknown, even though the synchronous reviewer can consume those checkpoints.
## What changed
Remove the synchronous reviewer's compaction hash compatibility check and the associated hash plumbing. Pass usable checkpoints to the backend for payload validation, while continuing to fail closed on unusable checkpoints and review errors.
## Testing
Update compaction and resume tests to expect retained evidence with different, missing, or empty reviewer hashes, while preserving rejection of empty checkpoint content.
GitOrigin-RevId: bbc4f5a2e697f832f815dcf8bda4d4a652f06b8a
## What changed
Add an adapter that delegates the shared controller interface to existing local agent operations, including lifecycle management, message delivery, status observation, budget accounting, and shared settings.
Align the trait signatures and documentation with local behavior: separate advisory capacity checks from execution tracking, preserve best-effort completion reporting, and return optional guardian evidence. Use `SessionId` for controller identity and replace paginated queries with loaded-agent listing by path prefix, removing the obsolete types and exports.
GitOrigin-RevId: 15bb7135e0f180d207390f6f2e75f63b9058816a
## What changed
- Return `StatusSubscription` streams of `AgentInfo` snapshots from local status subscriptions, including agent metadata and configuration.
- Emit the initial snapshot before subsequent coalesced updates. Use a weak thread reference and retain the last observed configuration so published final updates remain available after the runtime is dropped.
- Update completion notifications and `wait_agent` to consume snapshot streams, propagate subscription errors from `wait_agent`, and fall back to the latest status when a stream ends.
## Testing
Update the shutdown subscription test to verify that shutdown before the first poll preserves the initial `PendingInit` snapshot followed by `Shutdown`.
GitOrigin-RevId: beb46952cbcc9bddf65a4d6603fea939d5ace8b9
## What changed
- Request installed-plugin metadata with `includeExtensions=true` and carry optional `extensions` through the cache into `PluginSummary`.
- Add typed declarations for global, settings, thread, and file entrypoints, quick actions, settings tools, icons, and search mention providers. Update JSON schemas and TypeScript and Python bindings.
- Accept supported snake_case aliases and emit camelCase fields. Discard incompatible extension declarations without invalidating the installed-plugin inventory.
## Testing
Add an integration test covering extension metadata preservation, field normalization, and unknown entrypoint and quick-action types across live and cached `plugin/installed` reads. Update pagination assertions to require `includeExtensions=true`.
GitOrigin-RevId: b73b0d13c151a30dc1fb9cda70b5cd6d7e3e2441
## Why
Posting to a new channel subscribed its author to replies on that post, but not to new discussion roots in the channel. The creator could therefore miss notifications for subsequent discussions.
## What changed
Subscribe the author to the channel in the same transaction that creates the channel and its first post. Document this behavior in the API and the `new_channel_name` tool parameter.
## Testing
Update coverage to verify that channel creators receive notifications without explicit targeting and that posting to an existing channel preserves an explicit unsubscribe. Adjust thread-deletion test expectations for the additional persisted subscription.
GitOrigin-RevId: 5553ebc9f9b51456ab48886e9871733e93370a2b
## What changed
Add a V1 spawn regression test that removes the child from the thread manager during startup, before spawn reports its settings. Verify that the completed spawn event retains the role-configured model and reasoning effort, nickname, and role even when the child can no longer be looked up.
Also verify that the child receives its initial input with the effective settings and the parent receives a successful spawn result.
GitOrigin-RevId: 5e94e3ddb0feda0eaaa86e7539ef8c6720176f88
## Why
Posting to a discussion automatically subscribed its author, undoing an explicit unsubscribe and restoring unwanted reply notifications.
## What changed
Persist explicit opt-outs so posting follows a discussion by default but leaves unsubscribed agents opted out until explicitly subscribed again. Keep active subscriptions in the existing table for compatibility with older readers, and remove opt-outs when deleting a board. Update the API and tool descriptions to explain the behavior.
## Testing
Extend the local board test to cover reopening an older database, preserving opt-outs across reopen and subsequent posts, legacy subscription queries, explicit notifications without resubscribing, explicit resubscription, and board cleanup.
GitOrigin-RevId: 8b8f7f50cea5041541b8d93067c52db18cdde85c
## What changed
Return an `AgentInfo` snapshot captured before shutdown, including metadata for known unloaded agents. Use the snapshot's status and metadata in the tool's completion event and its status in `previous_status`, replacing the separate status subscription.
Preserve the pre-close status for error reporting when shutdown removes the target before a descendant fails to close. Propagate unexpected thread lookup errors before attempting shutdown.
GitOrigin-RevId: bdbd877aaf0389e830d6a7e84a5e14bb7d47277a
## Why
Remote compaction v2 excluded descendant progress messages from retained history but kept `CHANNEL_POST` messages from those same agents.
## What changed
Treat descendant `CHANNEL_POST` messages like `MESSAGE` progress updates when selecting history to retain after remote compaction v2.
## Testing
Extend the remote compaction test to verify that a child channel post is included in the compaction input and omitted from the follow-up request.
GitOrigin-RevId: 204bf44b8cddf1e6dc1e48234f51d4ac2aaf2e9f
## What changed
Allow `mcpServer/resource/read` to specify `target: {connectorId, linkId}` for direct hosted app reads without tool discovery, when supported by the backend. Require an explicit `linkId`: a string selects an account, while `null` requests no-auth access subject to backend policy.
Restrict direct targets to `codex_apps` and reject empty connector IDs, empty link IDs, and synthetic link IDs. Preserve originating app/account scope when `originCallId` and `threadId` are supplied, and retain discovery when `target` is omitted.
Update protocol schemas and TypeScript and Python models, preserving required-but-nullable `linkId` semantics in Python code generation.
## Testing
Extend resource-read tests to check target metadata with and without a thread, including explicit no-auth targets and omitted targets. Add Python model tests for string and null `linkId` values and rejection of a missing `linkId`.
GitOrigin-RevId: 8cf5595fbdd937193aeb529901fc95299f6e18ad
## What changed
Add `LocalAgentControl::resume_agent` to reuse an existing thread or restore it from its rollout when lookup returns `ThreadNotFound`. Return the agent's current status, metadata, and configuration snapshot.
Route the `resume_agent` tool through this method, replacing its status-based resume check and separate restoration helper.
GitOrigin-RevId: 2ae0572a030f169eca1760ba0aff1fb9e2ab6651
## Why
Accepted inter-agent messages can still be waiting in the submission queue when a worker appears idle. Evicting that worker can lose the queued work, while cancelling an eviction caller can leave shutdown unfinished and allow delivery to a closing runtime.
## What changed
- Pin V2 recipients until queued submissions are handled or dropped, and verify that delivery targets the registered runtime.
- Move `Submission` into core so it can carry the residency guard through queue handoffs.
- Give eviction exclusive access to each runtime and keep it counted against capacity until removal. Run teardown in a separate task so it completes even if its caller is cancelled, and remove registry and residency entries together.
## Testing
Add a regression test covering queued follow-up delivery, eviction refusal while mail is pending, cancelled eviction completing teardown, rejection of late delivery, and capacity reuse after removal.
GitOrigin-RevId: d6de3d68cb6b911942e9ddfc05c65b3741b796b2
## Why
Channel and thread subscriptions, or explicit `agents_to_notify`, could cause agents to receive notifications for their own posts.
## What changed
Exclude the author from notification recipients, even when explicitly targeted. Preserve the author's subscriptions so replies from other agents still reach them, and document this requirement in the board API.
## Testing
Update board tests to cover explicit self-targeting, subscribed authors, and delivery of other agents' replies. Update the model-context scenario and snapshot to verify posts remain searchable without a `CHANNEL_POST` self-notification.
GitOrigin-RevId: 0b2558e7df79122a6da06ad592f9735ba260cce1
## What changed
- Route both multi-agent spawn handlers through `LocalAgentControl::spawn`, accepting user input or an agent message.
- Centralize spawn message attribution and canonical path validation, and require message input to use `TriggerTurn`.
- Return the child's configuration snapshot alongside `LiveAgent`, so handlers obtain effective settings directly from spawning without a separate lookup.
- Update child test fixtures to use the shared spawn entry point.
GitOrigin-RevId: 9f9278df08041a62215f9ec3d38688c78fc5e0e2
## Why
MCP requests pass through background transport queues, so HTTP requests need the caller's trace context carried explicitly to preserve trace ancestry.
## What changed
- Capture W3C trace context in request metadata for tool and resource operations, custom requests, and event streams.
- Restore that context in an `mcp.http.request` span around HTTP POSTs, linking outgoing HTTP traces to the originating request.
- Preserve application metadata while replacing trace fields with the current caller's context and removing stale `tracestate`. Read the SDK's merged metadata so extension fields retain precedence over parameter metadata.
## Testing
Add a unit test for metadata merge precedence and an integration test covering concurrent paginated requests, tool calls, custom requests, and tool-call continuations across legacy and `2026-07-28` protocol modes. Verify HTTP trace ancestry, metadata preservation, and removal of stale `tracestate`.
GitOrigin-RevId: 0b22cd75f31f9fcb855b27fa8d34ecdffd6e3549
## Why
Clients with a gateway sign-in UI need to control when browser authorization starts and inspect credential readiness before making authenticated requests.
## What changed
- Add `initialize.capabilities.explicitGatewayOauth` to require explicit login while allowing existing credentials to refresh. Preserve automatic authorization for clients that omit the capability, and prevent later connections from undoing explicit opt-in.
- Add `account/gatewayOAuth/read`, `account/gatewayOAuth/login`, and `account/gatewayOAuth/cancel`, plus `account/gatewayOAuth/changed` notifications. Send the authorization URL only to the initiating connection and cancel its login on disconnect.
- Check gateway authentication before returning cached results from `model/list`, with restart guidance when provider settings have changed.
- Update protocol schemas, TypeScript and Python bindings, and document capability probing and the sign-in lifecycle.
## Testing
Add tests for passive readiness reads, credential reuse after login, token exchange failures, cancellation and immediate retry, connection ownership, legacy versus explicit login, and model-list authentication checks.
GitOrigin-RevId: a26e116a62c9f3db84dc238a40b7f4e816eb1594
## Why
Standalone web search selected a proxy route only for the initial endpoint. Redirect destinations can require a different system proxy route.
## What changed
- Add `RouteAwareClientPool` support to `ReqwestTransport` for both buffered and streaming requests, and use it for standalone web search.
- Preserve default Codex headers and Cloudflare cookie handling across routes, while retaining the default client behavior when route-aware handling is disabled or Codex is sandboxed.
- Share request construction so URL authentication and header precedence follow `reqwest` semantics, applying them once before redirects and TLS retries.
- Map route-aware failures to transport errors and remove request URLs from those errors.
## Testing
Add regression coverage for redirects through distinct proxies, preservation of POST bodies and default headers, URL authentication and header precedence, and transport error classification without URL leakage.
GitOrigin-RevId: 19a10a62118846db09dd95265dc277e54aac09ef
## Why
Injecting context before the first turn currently forces a full flush. Stores need a preparation checkpoint that can leave disposable context in memory, while local storage must keep prepared context durable before the first user input.
## What changed
- Add `PersistContext::ThreadPreparation` and `CodexThread::checkpoint_preparation()`, and use the checkpoint in `inject_response_items()`.
- Allow stores to defer rollout-derived metadata writes through `record_thread_metadata()`, including during preparation and execution checkpoints. Keep standard metadata updates synchronous.
- Flush local storage at preparation checkpoints so injected context survives restart.
## Testing
Add tests showing that preparation and first sampling can proceed without waiting for durable metadata. Cover prepared context in first and follow-up requests, plus durability before first input and restoration after restart, in both legacy and paginated history modes.
GitOrigin-RevId: 74f6bb1a5f8d47192364b8bba6afd703a3b7d688
## Why
Aligned equations and common optimization notation previously fell back to TeX source. Scripts without Unicode equivalents also prevented otherwise supported expressions from rendering.
## What changed
- Add display layouts for `aligned` and `\boxed`, preserving fraction geometry and alignment with surrounding math.
- Stack sum limits and `\underset`/`\overset` annotations in display math, with compact forms for inline math and nested arguments.
- Support `\substack`, uppercase `\mathcal`, and single-grapheme `\widehat`.
- Preserve scripts without Unicode equivalents using explicit grouping, such as `x_{gpt}` and `x^{q+1}`.
- Keep layouts bounded and retain source fallback for unsupported input or expressions that do not fit.
## Testing
Add snapshots and regression tests for optimization models, display limits, grouped scripts, fraction alignment, narrow-width fallback, malformed input, and layout bounds. Add streaming coverage comparing character-by-character output with complete rendering at wide and narrow widths in rich and raw modes.

## Why
Conversations open in another app disable the composer. Let users continue in an editable fork while the original conversation remains owned by that app.
## What changed
- Add an `f`/`F` shortcut and footer hint to the locked conversation view, preserving local drafts and queued prompts in the fork.
- Show “Forking conversation…” while a fork is pending, block additional key input, and discard buffered input after forking from the locked view.
- Replace the previous session summary after a fork with “Fork created. You can continue here.”
- Keep the locked view and draft intact if the fork request fails.
## Testing
Add tests for shortcut ownership and modifiers, repeated input, editable forks that preserve drafts and queued prompts without taking the source lease, and failure recovery. Add snapshots for fork progress, completion, and the updated footer.

## What changed
Promote `daemon_auto_start` to stable and enable it by default for eligible interactive launches. Remove its entry from `/experimental`.
## Testing
Update daemon startup, `--no-daemon`, and startup failure tests to exercise the default without explicitly enabling the feature. Disable daemon startup in unrelated TUI and path-safety test fixtures.

## What changed
Default `tui.fullscreen_transcript` to `true`, including when the `[tui]`
section is absent, and apply the same default to the first frame. Update the
configuration schema to match. Alternate-screen restrictions still take
precedence, and `tui.fullscreen_transcript=false` restores terminal scrollback.
## Testing
Update configuration and startup tests for the new default, including an empty
`[tui]` section and `--no-alt-screen`. Adjust PTY tests to cover default fullscreen
entry and explicit opt-out to terminal scrollback.

## Why
Reaching the pending tool-call limit could evict finished empty cells even though removing them frees no pending-call capacity. This loses the metadata needed to certify an empty tool-call inventory on a later `wait`.
## What changed
Only evict cells with pending calls when reclaiming pending-call capacity. Keep empty cells eligible for eviction when a cell slot is needed.
## Testing
Extend recorder coverage to check empty inventories under pending-call pressure in fresh and resumed sessions. Add a code-mode integration test verifying that `wait` serializes an empty inventory with `tool_calls_complete: true` while another cell has filled the pending-call budget.

## What changed
- Add `GatewayLoginControl` so hosts can require caller-initiated browser authorization while retaining automatic login by default.
- Expose passive readiness checks, scoped status subscriptions, and cancellable browser login that reports success after credentials are persisted.
- Return non-retryable request errors for `LoginRequired` and `LoginInProgress`, while preserving retries for transient authentication failures.
- Keep rejected credentials unready until replaced, and prevent slow readiness reads from blocking cached requests or overwriting newer credentials.
## Testing
Add coverage for login cancellation, status notifications, external credential recovery, concurrent credential I/O, legacy automatic login, and request retry behavior.
