## Why
Remote plugin requests did not use Codex's effective outbound proxy policy, so
they could bypass configured system proxy and PAC routing.
## What changed
- Route remote plugin catalog, mutation, sharing, upload, and bundle download
requests through the configured route-aware HTTP client.
- Select routes using the complete request URL, including encoded query
parameters and backend-provided signed upload or download URLs.
- Preserve standard Codex headers and suppress diagnostics for URLs or headers
that may contain credentials.
## Testing
Add coverage for route selection of catalog queries, workspace plugin uploads,
and backend-provided bundle download URLs.
GitOrigin-RevId: 106936659e21decf145b6ab4d4be84992e386861
## Why
The curated plugin startup sync can fall back from Git to HTTP, but those
requests did not use Codex's effective outbound proxy policy.
## What changed
- Thread the configured HTTP client factory into curated plugin sync.
- Route GitHub API, zipball, backup metadata, and returned download URLs
through the route-aware client when system proxy support is enabled.
- Preserve the existing default HTTP client behavior, including its custom CA
fallback, when system proxy support is disabled.
- Apply the standard Codex headers to startup-sync HTTP requests.
## Testing
Add coverage that records route selection for repository, archive, metadata,
and backend-supplied download URLs, and verifies standard headers are sent.
GitOrigin-RevId: e1ea13bdab58a84c9948a2c8b82a5ec5c964ea99
## Why
Backend-backed features need to use the same outbound routing configuration as the rest of Codex.
## What changed
- Build the backend client on a route-aware client pool supplied by `HttpClientFactory`.
- Pass the configured factory through app-server account requests, cloud config loading, cloud tasks, and memory rate-limit checks.
- Preserve task query encoding, authentication headers, JSON request bodies, and ChatGPT cookie handling during the migration.
## Testing
- Add backend-client tests for proxy-policy propagation, task query encoding, bearer authentication, and JSON request bodies.
GitOrigin-RevId: c17d162e0dce9cec758df7cdeecf982207c6512b
## Why
Goal-first and forked threads could create rollouts without recording their
effective thread settings. Resuming those threads after a restart could then
use current configuration instead of the settings selected when the thread was
created.
## What changed
- Persist a `thread_settings_applied` item when a goal first materializes a
rollout, including a follow-up snapshot if settings changed concurrently.
- Append each fork's effective settings after its copied history so they take
precedence over inherited settings during resume.
- Centralize conversion from `ThreadConfigSnapshot` to
`ThreadSettingsSnapshot`.
## Testing
Added coverage that restarts the app server and verifies goal-first and forked
threads retain their respective `approvals_reviewer` settings.
GitOrigin-RevId: 6cb9aaae73bbe9ca432831cff7e826f95ffd6d01
## Why
Sandboxed process launch through the exec server was unsupported on Windows.
## What changed
- Add a shared native process launcher that selects the Windows sandbox session backend when required and otherwise launches PTY or pipe-based processes.
- Pass Windows permission, workspace-root, proxy, filesystem-override, and desktop settings through exec-server process preparation.
- Preserve piped stdin and inherited file descriptors across the shared launch path.
## Testing
- Verify that a remote Windows sandbox process accepts stdin while blocking a write under a read-only policy.
- Enable workspace-root sandbox tests on native Windows while continuing to skip environments that cannot emulate Windows sandbox semantics.
GitOrigin-RevId: 6719ccbe87ad0d5a57af56503e3f23f894c60a71
## What changed
- Add `iconUrlDark`, `distributionChannel`, `installUrl`, and
`pluginDisplayNames` to the experimental `app/read` connector metadata.
- Populate plugin display names from enabled plugins without starting their MCP
servers.
- Accept both dark-icon field spellings from the batch API and keep the new
upstream fields optional for compatibility with older responses.
## Testing
- Cover the serialized response fields, legacy batch responses, and plugin
display-name lookup without MCP startup.
GitOrigin-RevId: 68601a104de839c0f4f4621d33b0e4d08ad88c64
## What changed
- Make the MCP connection manager's event sender optional.
- Skip startup notifications when a caller has no session event stream.
- Decline interactive MCP elicitations in that mode while allowing the
underlying operation to continue.
- Update threadless resource reads, status snapshots, and connector discovery
to use the channel-free path.
## Testing
- Extend the app-server MCP resource test to verify that a threadless resource
read declines an elicitation and still returns the resource contents.
GitOrigin-RevId: 65fea152adbc02a78e09a40cae4134b6dccffd34
## What changed
- Add `additionalContextLimit` to command hook configuration for events that can emit `additionalContext`.
- Apply the limit independently to each hook's context before it is sent to the model. Unset values retain the 2,500-token default, while `0` disables spilling for that hook.
- Expose configured limits through app-server hook and requirements responses, and show them in the TUI hooks browser.
## Testing
- Cover JSON and TOML parsing, discovery and hashing, per-hook spilling behavior, app-server responses, and TUI rendering.
GitOrigin-RevId: 55ddc2dbbdf9067dceee3e1968c03617bbf6bcea
## What changed
- Resolve the turn ID for restored token usage before sending resume and fork responses, avoiding a clone of the full thread history.
- Add `ThreadHistoryBuilder::active_turn_id` so attribution can inspect the active turn without materializing its items.
- Stop history reconstruction at the latest persisted `TokenCount` and verify that a later tail turn does not receive the replayed usage.
GitOrigin-RevId: 69c4a9fe04770d1a938470afc933431e61670094
## Why
The first session metadata record defines a rollout's history mode. If that
record uses an unsupported mode, skipping it as a parse error can cause later
metadata copied from fork history to be treated as canonical.
## What changed
- Validate session metadata history modes before deserializing rollout lines,
while continuing to tolerate unknown modes in copied fork history.
- Simplify thread status registration to pass only the thread ID instead of a
fully materialized `Thread`.
GitOrigin-RevId: 9de4313d4a76b279d32bb49b2016a4f5d07507c1
## Why
Paginated threads need explicit user-facing names to remain distinct from
derived titles and previews without requiring rollout metadata writes.
## What changed
- Add a nullable `name` column to persisted thread metadata and use it as the
canonical name for paginated threads.
- Route paginated name updates through the state database while retaining the
name index as best-effort compatibility data and preserving legacy thread
behavior.
- Return persisted names when reading, listing, searching, and resuming
paginated threads, and include them in state-database search matching.
## Testing
- Cover paginated name updates, reads, list/search results, and metadata-only
resume behavior, including stale or unavailable compatibility data.
GitOrigin-RevId: 5ac4dfa2a83682b43d59ecc87e0f515580164dca
## Why
Clients that use full-history resume or request full items in turn pages should
work consistently across legacy and paginated threads.
## What changed
- Materialize complete turns and items from the paginated projection for
`thread/resume` and `thread/turns/list` when requested.
- Support `initialTurnsPage` during paginated resume, including merging a live
active turn while preserving the requested page size and cursors.
- Keep metadata-only resume behavior and backwards cursors available through
`excludeTurns: true`.
## Testing
- Extend app-server coverage for full paginated history, full item views, and
initial resume pages on running threads.
GitOrigin-RevId: e340f44d631ce135895c95d7e1baa7bfecd86e71
## What changed
- Add an optional `initialItems` field to `thread/realtime/start` for seeding
realtime V3 session history with `user`, `developer`, and `assistant` text.
- Encode the items in Frameless Bidi session bootstrap payloads for websocket
and WebRTC transports while preserving existing payloads when the list is
omitted or empty.
- Reject non-empty initial items for V1 and V2, more than 128 items, any item
over 8,192 estimated tokens, or a combined total over 8,192 estimated tokens.
## Testing
- Cover protocol serialization, app-server forwarding, websocket and WebRTC
payloads, empty-list compatibility, version checks, and size limits.
GitOrigin-RevId: 09af367f9a07543e3f8d59b7fa5387f932dc5a6a
## What changed
- Accept `LISTED` discoverability in `plugin/share/updateTargets` and forward it to the remote plugin sharing API.
- Update the generated JSON schemas and TypeScript type with the new enum value.
## Testing
- Add an app-server integration test that publishes a workspace plugin and verifies the `LISTED` request and response.
GitOrigin-RevId: 978f4b94b318e772bf80347e58dd5b1d2819a653
## What changed
- Add the experimental `thread/searchOccurrences` app-server method for case-insensitive literal search across visible user messages and final assistant messages without replaying the thread.
- Return paginated snippets with UTF-16 match ranges and `thread/turns/list` cursors for navigating to each matching turn.
- Index persisted item types to efficiently select searchable messages from paginated thread history.
## Testing
- Add an app-server integration test covering pagination, steering messages, final-answer selection, Markdown normalization, and UTF-16 offsets.
GitOrigin-RevId: e80160e0f83eb4e5db8de862307085093bee362b
## What changed
- Add `codexResponseHandoffMode` to `thread/realtime/start` for V3 sessions, with `thinking` as the default and `commentary` and `bemTags` routing modes.
- Map BEM `analysis` and `commentary` output to the commentary channel and `final` output to the speakable channel, while preserving the original BEM envelope. Unrecognized output falls back to speakable.
- Mark explicit speech appends as speakable and stop adding the legacy `"Agent Final Message"` prefix to V3 handoffs. V1 and V2 continue to ignore the new setting.
## Testing
- Cover channel selection for every routing mode, streamed BEM header parsing, fallback behavior, explicit speech, and V1 compatibility.
GitOrigin-RevId: 1974578257488f2914b252c9c1990ba38831c96b
## What changed
- Add nullable `mustShowInstallationInterstitial` metadata to app-server
`PluginSummary` responses.
- Preserve the remote service value through catalog, installed-plugin cache,
list, read, and share-list paths.
- Return `null` for local plugins and remote responses that omit the field so
clients can fail closed when the policy is unavailable.
## Testing
- Cover `true`, `false`, and missing values across remote summary paths and
app-server plugin endpoints.
GitOrigin-RevId: db79702ee2bfa800a9910d64d933bcabecb3ce70
## What changed
- Add the `SessionEnd` hook event to hook configuration, protocol schemas, analytics, and the hooks browser.
- Run matching hooks for root threads during shutdown, including app-server archive, delete, idle unload, and graceful shutdown. Flush the transcript first and provide the session ID, transcript path, working directory, and `reason: "other"`.
- Keep teardown bounded: hook output is advisory, the default timeout is one second, configured timeouts are capped at three seconds, and async hooks run synchronously with a warning.
## Testing
- Cover transcript availability, matcher selection, timeout normalization, ignored control output, subagent exclusion, archive/delete ordering, and graceful shutdown of multiple loaded threads.
GitOrigin-RevId: 5d19a658677a137caf836ed5042dcb43f5eb6d1a
## What changed
- Stream V3 agent message deltas to `delegation.context.append` at 200 ms intervals instead of waiting for each completed message.
- Send commentary without a prefix and label final or phase-less V1/V3 output with `"Agent Final Message":`.
- Bound streamed output while preserving both its beginning and final tail when truncation is required.
- Remove `codexResponseHandoffPrefix` from `thread/realtime/start`; unknown fields from older clients remain ignored.
## Testing
- Cover incremental V3 commentary and final output, Unicode-safe truncation, V1/V3 phase labeling, and legacy request compatibility.
GitOrigin-RevId: 633c18b5eb9a4f5756a264b63b7bfc185b073951
## What changed
- Add `app/installed` to return each connector observed in the committed runtime tool snapshot, including its runtime name and effective `enabled` and `callable` state.
- Support evaluating thread-specific configuration with `threadId` and refreshing the hosted connector tool snapshot with `forceRefresh`.
- Preserve observed connector identities as disabled when global or workspace policy disables Apps, and retain the previous snapshot when a refresh fails.
## Testing
- Cover cached and forced reads, policy and configuration filtering, thread-specific configuration, snapshot refresh failures, and protocol serialization.
GitOrigin-RevId: f697b6fb501b7d329a169e947a1c1607806222fe
## Why
Multi-agent V2 spawned threads are controlled by their parent and reject direct
app-server input. The TUI should expose that ownership instead of presenting an
input flow that the server will reject.
## What changed
- Add the experimental `Thread.canAcceptDirectInput` capability for loaded
threads and populate it from the same policy used to validate `turn/start`
and `turn/steer`. Stored, unloaded threads report `null`.
- Carry the capability through TUI thread discovery, selection, startup, and
resume flows, with a compatibility fallback for older app servers.
- Present parent-owned threads as view-only, preserve drafts and queued input,
block agent-directed commands and settings shortcuts, and keep local
navigation and inspection commands available.
## Testing
- Cover V1 writable and V2 view-only spawned threads through selection and
resume.
- Cover composer submission paths, queued and initial input preservation,
allowed navigation commands, settings shortcuts, and the view-only UI.
GitOrigin-RevId: 495ad051249e5577fb0b0c1cc8c40a0998d04918
## What changed
- Add the experimental `app/read` request for fetching metadata for up to 100
app IDs, with optional display-only tool summaries.
- Preserve first-request order while deduplicating IDs, and report unknown or
unauthorized apps as partial misses.
- Cache metadata by backend and ChatGPT account/workspace identity, refetch
metadata-only entries when tools are requested, and preserve cached records
when a backend request fails.
## Testing
- Cover request serialization, ordering, deduplication, partial misses, caching,
tool-summary refetches, backend failures, cache isolation, and the ID limit.
GitOrigin-RevId: 55fc3281d99291e76d6c4a581e8d11569d3cb1ac
## What changed
- Emit one final `app/list/updated` notification for an initial cached
`app/list` request so other initialized clients can refresh.
- Suppress duplicate notifications for unchanged cached continuation pages.
- Preserve progressive update notifications for `forceRefetch: true` requests.
## Testing
- Cover notification behavior for cached initial and paginated requests.
GitOrigin-RevId: 54f2d25a0adf6e0707402328b4c81fa5f950cf9a
## What changed
- Remove `template_id` from MCP tool call items and lifecycle events.
- Remove `templateId` from app-server `McpToolCallAppContext` responses and generated schemas.
- Update protocol conversions, documentation, and existing test expectations for the revised metadata shape.
GitOrigin-RevId: f2b1304eadff661eec3966673ea71206b1542b98
## Why
Windows firewall enforcement is tied to the logon-user sandbox identities. Proxy-enforced commands therefore need the elevated backend even when the configured sandbox mode is the default restricted-token mode.
## What changed
- Select the elevated Windows sandbox backend whenever a command uses the managed network proxy.
- Remove configuration and startup checks that required users or managed requirements to select the elevated sandbox explicitly.
- Start and expose managed network proxy state consistently on Windows.
## Testing
- Verify that proxy enforcement selects the elevated backend for the restricted-token sandbox mode.
GitOrigin-RevId: e01ac052587721c468a8fbcf4e2c7c5a185a3e05
## What changed
- Allow `thread/start` to select experimental `historyMode: "paginated"` when the thread store supports turn and item pagination.
- Resume paginated threads with bounded model context and require `excludeTurns: true` instead of loading full history.
- Return `turnsBackwardsCursor` and `itemsBackwardsCursor` from `thread/resume` so clients can hydrate durable history through `thread/turns/list` and `thread/items/list` while newer records arrive through live notifications.
- Reject operations that still require full history, including `initialTurnsPage`, `thread/read` with `includeTurns: true`, `thread/rollback`, and detached review.
- Make item cursors independent of the optional `turnId` filter.
## Testing
- Cover paginated thread start, cold and live resume, backwards cursor hydration, metadata reads, unsupported operations, and stores without pagination support.
GitOrigin-RevId: c42f9b268e29d049843330f474fa3ecde12f5b8a
## What changed
- Add experimental `beforeTurnId` support to `thread/fork` for copying history strictly before a turn, including an in-progress turn.
- Use before-turn forks for TUI backtracking and safety retries so the replacement prompt retains thread context instead of recreating the branch from the preceding turn or a new thread.
- Add experimental `deferGoalContinuation` support so safety-retry forks can inherit an active goal while waiting for the replacement turn before automatic continuation resumes.
- Hide duplicated nested-review prompts when replaying history or selecting a prompt to edit.
## Testing
- Cover before-turn truncation, fork validation, active-goal inheritance, TUI safety retries, backtracking, and nested-review replay.
GitOrigin-RevId: 4915d85ae1929a0b8c40f3ed7dca29c7a5bdcdf3
## Why
Starting a new session should not have to wait for an unchanged stdio MCP
server to initialize before its tools can be presented to the model.
## What changed
- Cache recent tool catalogs for matching stdio MCP server configurations and
use them while a new live connection starts in the background.
- Bound the process-wide cache to 32 entries with a 30-minute TTL, and key
entries by the server configuration, environment, working directory, and
elicitation capabilities that affect the catalog.
- Keep connection-specific instructions and tool annotations out of cached
catalogs. Resolve tool calls against the live connection so tools that are
unavailable or hidden in the new session cannot be invoked from stale data.
- Publish only the newest completed catalog fetch and do not cache HTTP servers
or stdio configurations that depend on remotely sourced environment values.
## Testing
- Add coverage for cache expiration, environment changes, catalog sanitization,
and out-of-order refreshes.
- Add an end-to-end test that starts inference from cached definitions while a
replacement MCP process initializes, then verifies calls and visibility
against the live process.
GitOrigin-RevId: 2ed0f29ba53ace12532730f951b175c588aa3ae7
## What changed
- Add `subErrorType` to external agent config import failures and carry it through progress and completion notifications, persisted import histories, and analytics.
- Expose plugin store failure subtypes from `PluginInstallError` so manual installs and imported plugins report details such as `failed_to_copy_plugin_file` while failures without a subtype remain `null`.
- Keep existing persisted import records compatible by defaulting the new field when it is absent.
## Testing
- Cover store I/O subtype extraction, analytics serialization, persisted import histories, and migration notification fixtures.
GitOrigin-RevId: ec1a85623fc826cbd7cfe9f55c2dd2bc86665937
## Why
Amazon Bedrock can use either a Codex-managed API key or credentials managed by
AWS, so logout must not remove or misrepresent credentials that Codex does not
control.
## What changed
- Remove the managed Bedrock key on logout and clear `model_provider` only when
its user-config value is still `amazon-bedrock`.
- Reject logout for AWS-managed Bedrock credentials without changing existing
authentication or configuration.
- Add a `test-logout` app-server test-client command that waits for the
resulting `account/updated` notification.
## Testing
Add coverage for managed and AWS-managed Bedrock logout, concurrent provider
changes, config reload failures, and conditional user-config cleanup.
GitOrigin-RevId: a003c0ec27ad7b36d499fe7b63ab4a0dd6369b4f
## What changed
- Handle experimental `account/login/start` requests with `type: "amazonBedrock"`.
- Validate the API key and Mantle region, persist the managed credential, select the `amazon-bedrock` model provider, and emit the standard login and account-update notifications.
- Reload configuration for account and authentication status reads so the newly selected provider is visible immediately, with the startup configuration as a fallback.
- Extend the app-server test client with an Amazon Bedrock login mode that redacts API keys from request logs.
## Testing
- Add app-server coverage for successful login, credential and provider persistence, notifications, refreshed account state, invalid inputs, conflicting configuration, forced ChatGPT login, external authentication, and configuration reload failure.
GitOrigin-RevId: bf3ae98375caee41e78d2cdc677127138184c17a
## Why
Detached reviews should behave like ordinary forked turns so clients get the normal steering, tool, permission, and item-stream behavior.
## What changed
- Add a bundled `$review-agent` skill with read-only, defect-first review guidance.
- Start detached reviews through `AgentRunner` with a target-specific prompt that explicitly references the bundled skill. Keep inline reviews on the existing review-mode flow.
- Continue emitting the detached review thread and turn identifiers through the app-server API.
## Testing
- Update the detached review integration test to verify the forked turn prompt, ordinary turn completion, and selection of the bundled skill when a user skill has the same name.
GitOrigin-RevId: 979664cd80800fb0d51eabdc4e3211da90c12db9
## Why
Clients could discover threads with paginated history, but could not page their
turns through `thread/turns/list`.
## What changed
- Route `thread/turns/list` for paginated threads through the thread store,
preserving cursors, sort direction, turn status, timing, errors, and the
requested `summary` or `notLoaded` item view.
- Reject the `full` turn item view for paginated threads and direct clients to
`thread/items/list` for complete item pagination.
- Return each item page entry with both its containing `turnId` and `item`, so
clients can regroup thread-wide pages into turns.
- Expose local thread-store turn and item pagination through the `ThreadStore`
implementation.
## Testing
Added app-server coverage for paging projected turns and items, item views,
cursors, turn metadata, and rejection of the unsupported `full` view.
GitOrigin-RevId: 9c4a127a9b4fa91313f0e87494c62fe2e3a06f19
## What changed
- Check the source thread's `history_mode` before loading its history for
`thread/fork`.
- Return the existing `paginated_threads is not supported yet` method-not-found
error for paginated source threads.
## Testing
- Add an app-server integration test covering rejection of a paginated source
thread.
GitOrigin-RevId: 49b4b8aef7c9488eec93c24e831cea6382f8c995
## Why
Clients that account for individual upstream Responses API calls need the exact
usage for each completion rather than accumulated or estimated thread usage.
## What changed
- Add the opt-in `rawResponse/completed` app-server notification with the
`threadId`, `turnId`, `responseId`, and upstream `usage` payload.
- Emit the transient event for normal turns and compaction requests when
`experimentalRawEvents` is enabled. The event is not persisted or replayed,
and `usage` is `null` when the upstream response omits it.
- Export the notification in the app-server schemas and document its behavior.
## Testing
- Cover exact token breakdowns for turn and compaction completions.
GitOrigin-RevId: 49040a060bf1784c1ff1dd62112efb4a778428c4
## Why
Multi-environment turns can run against different filesystems, so a single
thread-wide workspace-root list cannot accurately describe every selected
environment.
## What changed
- Add optional `runtimeWorkspaceRoots` to each app-server environment selection.
Omitted roots default to that environment's `cwd`, while an empty list selects
no roots.
- Carry environment-native roots through turn selection, model-visible context,
permission materialization, and tool sandboxing.
- Keep the top-level `runtimeWorkspaceRoots` field as a compatibility input when
constructing default environment selections; explicit selections use their
own roots.
## Testing
- Cover thread and turn API defaults, overrides, empty roots, and schema
round-tripping.
- Verify foreign roots remain model-visible and remote execution applies the
target environment's roots before sandbox selection.
GitOrigin-RevId: c6e7a62883c45c676c153055f46a55ee15a323a4
## What changed
- Project durable paginated rollout records into rebuildable SQLite tables for turns, items, and projection progress while keeping JSONL as the source of truth.
- Add cursor-based local reads for turn summaries and thread or per-turn items, including archived-thread and history-mode validation.
- Serialize writes, shutdown, and deletion per thread so projection updates cannot race cleanup, and remove projected rows when a thread is deleted.
- Preserve stable item ordering while updating repeated snapshots and expose structured turn error details.
## Testing
- Cover projection, snapshot updates, summary recovery, pagination, failure handling, shutdown flushing, legacy-mode rejection, and deletion races.
GitOrigin-RevId: 34533185ece7f1f5690004c7f12b0f1f34dc2640
## What changed
- Add the experimental `environment/status` request for inspecting a configured environment without starting or reconnecting it.
- Report `ready`, `pending`, `disconnected`, or `unknown`, including error details for disconnected and unknown environments.
- Probe ready remote environments over their existing exec-server connection.
## Testing
- Add an app-server integration test covering local and remote ready, pending, disconnected, and unknown environments.
GitOrigin-RevId: 397bba603aa9e0b59008ee6cb7cbde46e357652c
## What changed
- Include the active Codex Apps tools cache and connector directory cache, when available, in diagnostic uploads that include logs.
- Resolve cache paths from the current authentication context and use stable attachment filenames.
- List both optional cache files in the upload consent dialog.
## Testing
- Add coverage for selecting existing active cache files, including a directory cache without an account ID.
- Update consent dialog snapshots to include the optional attachments.
GitOrigin-RevId: 1d4ffbf2bcb96653f03dc25f91d80dd65038d585
## What changed
- Add an optional `source` selector to `externalAgentConfig/detect`, while preserving the existing behavior for omitted, `null`, and unrecognized values.
- Pass `claude-code` as the source for TUI detection and import requests.
- Move source-specific migration behavior behind an adapter boundary and consolidate session migration into `codex-external-agent-migration`.
## Testing
- Cover explicit, omitted, and unknown detection source values with app-server protocol tests.
- Add unit coverage for the extracted migration and hook helpers.
GitOrigin-RevId: 63bd3dcb485f3ad7bd996022db4e351506aeea77
## Why
Network proxy enforcement on Windows requires the elevated sandbox backend. Silently selecting that backend for an unelevated configuration makes the effective sandbox differ from the configured mode.
## What changed
- Reject enabled network proxy configurations on Windows unless managed requirements allow only the elevated sandbox and `windows.sandbox` resolves to `"elevated"`.
- Preserve the configured sandbox backend during execution and validate proxy compatibility at config loading, sandbox setup, and process launch boundaries.
- Defer this validation during cloud-config bootstrap so authoritative managed requirements can be loaded first.
- Do not start or expose disabled Windows proxies, and render transitions to disabled networking as `<network enabled="false"></network>`.
## Testing
- Cover Windows requirement and sandbox compatibility matrices, bootstrap behavior, backend selection, disabled proxy handling, and environment-context updates.
GitOrigin-RevId: bfa1dda98594e0db61883f8e7f65bd560e3453e6
## Why
`Max` and `Ultra` consume usage limits faster than standard reasoning levels, so they should not be selected accidentally while navigating the normal effort scale.
## What changed
- Move `Max` and `Ultra` behind a `More reasoning…` entry with a dedicated warning and descriptions.
- Keep the reasoning shortcuts from silently increasing into advanced efforts.
- Apply `Ultra` to the active conversation without changing defaults for new threads, while preserving it across mode switches and thread resumes.
- Record applied thread settings in thread metadata, including explicit clearing of reasoning effort, so resumed threads restore their latest model settings unless the user supplied an override.
## Testing
- Add TUI coverage for the advanced picker, shortcuts, Plan mode, configuration defaults, and resumed conversations.
- Add app-server and thread-store coverage for persisting, clearing, and restoring model and reasoning settings.
GitOrigin-RevId: 6708c7c2e8d38f491bf63000ea34f83476afdfe6
## What changed
- Move the Codex Apps tool cache into a reusable `codex-connectors` runtime manager keyed by account and workspace.
- Represent cached tools as atomically published snapshots with refresh timestamps while preserving the newest accepted fetch generation.
- Harden disk persistence with bounded reads, atomic file replacement, and serialized writes so an older fetch cannot overwrite newer state.
## Testing
Add coverage for identity isolation, snapshot timestamps, oversized cache files, atomic replacement, and concurrent persistence ordering.
GitOrigin-RevId: 5ea2234469daae3abf54b030244c3251de62ca5a
## What changed
- Pass the parent turn's effective permission profile to the memory consolidation agent, including thread-level permission and legacy sandbox overrides.
- Preserve disabled and externally enforced permission profiles instead of replacing them with a managed sandbox.
- Continue restricting consolidation to the memory root without network access when the parent uses Codex-managed permissions.
## Testing
- Add coverage for disabled, external, and managed parent permission profiles.

## Why
Paginated thread history needs durable ordering so consumers can process a rollout suffix without rebuilding all earlier history.
## What changed
- Add optional, zero-based ordinals to `RolloutLine` records in paginated rollouts while leaving legacy rollout serialization unchanged.
- Continue ordinals from the last valid record when appending or resuming, including after gaps or an incomplete tail, and reject overflow without appending.
- Add a stateless `project_rollout_line` helper that maps canonical turn lifecycle and completed-item records into thread-history change sets.
## Testing
- Cover ordinal assignment, legacy compatibility, resume and tail recovery, overflow handling, and thread-history projection for completed, failed, and interrupted turns.

## What changed
- Carry newly installed or updated remote plugin metadata through effective-plugin refresh callbacks, including coalesced refreshes.
- After a successful refresh, record the current hook hashes for listed workspace plugins associated with the active account while preserving existing hook settings and unrelated state.
- Serialize the background trust write with config mutations, and leave hooks untrusted if the write fails or the active account changes.
## Testing
- Cover eligible plugin selection and escaped hook config keys.
- Verify end-to-end trust for newly materialized plugin hooks, preservation of existing config, and fail-closed behavior when config cannot be written.

## What changed
- Allow the local thread store to create paginated threads while keeping them unsupported through the app-server API.
- Filter live append items using the history mode recorded with the thread's live recorder, so paginated threads persist canonical `ItemCompleted` events instead of legacy history events.
## Testing
- Add a local-store test that creates a paginated thread and verifies that a paginated item is persisted while a legacy user-message event is omitted.

## What changed
- Add optional `scheduledTasks` metadata to `plugin/read` responses for remote
plugins, including hourly, daily, weekday, and weekly schedules.
- Preserve the distinction between unavailable metadata (`null`) and a catalog
response containing no scheduled tasks (`[]`). Local plugin details return
`null`.
- Export the corresponding Rust, JSON Schema, and TypeScript protocol types.
## Testing
- Cover scheduled-task deserialization and propagation through `plugin/read`.
- Verify missing and empty remote metadata remain distinct.

## Why
App-server clients can report whether Amazon Bedrock is using
AWS-managed credentials or a Codex-managed API key, but they do not have
a matching API for creating the managed login. This PR defines that
experimental wire contract independently from its implementation.
Managed Bedrock API keys are already a primary `CodexAuth` mode. The API
therefore describes a normal Codex login that replaces the current
stored auth rather than introducing provider-scoped credential storage.
## What changed
- Add the experimental `amazonBedrock` variant to `account/login/start`.
- Accept an API key and AWS region and return a matching discriminated
response.
- Gate the request behind the app-server `experimentalApi` capability.
- Regenerate the JSON and TypeScript protocol schemas.
- Document the login contract, notifications, primary-auth replacement
semantics, restart boundary, and non-transactional durable writes.
## Impact
This PR defines the API shape but does not implement login behavior. The
next PR adds validation, persistence through the existing Codex auth
lifecycle, provider selection, and notifications.
## Validation
- `just test -p codex-app-server-protocol`
## Stack
1. **#31327 Managed Bedrock experimental API** — base: `main`
2. #31326 Managed Bedrock login — base: `codex/managed-bedrock-api`
3. #31325 Managed Bedrock logout — base:
`codex/managed-bedrock-login-v2`
## Summary
- discover enabled-plugin marketplace sources from the user-level known
marketplace registry
- preserve scoped settings and supported Git/directory declarations,
falling back to the matching registry `installLocation` for file, URL,
npm-hosted, and inline marketplace sources
- resolve relative registry materialization paths against the
external-agent home
- reuse the existing marketplace add and plugin install flow during
import
- emit `plugin_not_found` tracing and analytics with plugin and
marketplace identity
## Why
Enabled plugins can remain in settings after their marketplace source
has moved into the user-level registry. Import detection previously
skipped those plugins because it only consulted settings-defined
marketplace sources.
## Impact
`/import` can now restore those marketplaces and install their enabled
plugins through the normal plugin installer, including npm, Git, and
local plugin sources. Missing plugins remain visible in import results
and the plugin-install failure analytics stream.
