## Why
`thread/fork` rejected threads using paginated history, so they could not use the same fork workflow as legacy threads.
## What changed
- Create paginated forks by referencing a frozen source-history prefix while persisting only child-owned records in the new rollout.
- Support latest, `lastTurnId`, and `beforeTurnId` boundaries, including inherited lineage, model-context reconstruction, interruption markers, and approval-reviewer inheritance.
- Make paginated reads and occurrence search traverse referenced history while excluding source records added after the fork.
- Coordinate fork preparation with archive and delete operations, and materialize compressed rollouts before they become fork references.
## Testing
Added app-server and thread-store coverage for boundary selection, active turns, inherited reads and search, compressed lineage, and concurrent source lifecycle operations.
GitOrigin-RevId: 66052d69517d7fb97a3b7817ab77a39c5ad995fd
## What changed
- Add a best-effort MCP configuration refresh that logs per-thread load errors and continues refreshing the remaining threads.
- Use the best-effort path after account or plugin changes before invalidating MCP runtimes.
## Testing
- Add a test confirming that a thread with a configuration load failure does not prevent healthy threads from receiving updated configuration.
GitOrigin-RevId: 34708d46f63fbe8617567ced16b4c199456ab078
## Why
MCP config reloads updated resolved server and authentication values, but did not
carry managed server constraints or plugin requirements into active threads.
## What changed
- Refresh MCP state from the typed thread config, including its managed
requirements, while retaining the thread's user layer and unrelated settings.
- Apply the refreshed config directly through `CodexThread` instead of encoding it
as a protocol operation.
- Re-evaluate effective plugins immediately after account changes so their MCP
requirements reach existing threads.
## Testing
- Cover replacement and enforcement of managed server and plugin requirements.
- Verify refreshed MCP settings are installed without changing the active model.
GitOrigin-RevId: 3cf0d69f51ef4893a4d722ee803fcbfdf1cd959e
## Why
MCP configuration can change while a thread is still starting, before it appears in the thread manager's loaded-thread list. In that window, invalidation could miss the new thread and leave it with a stale MCP runtime.
## What changed
- Centralize MCP runtime invalidation in `ThreadManager` so it refreshes loaded threads and marks in-progress thread startups for refresh after publication.
- Use the centralized invalidation path for account and plugin changes.
- Invalidate MCP runtimes after successful server and plugin OAuth logins.
## Testing
- Add a regression test that pauses thread startup, invalidates MCP runtimes, and verifies that the newly published thread refreshes its MCP projection.
GitOrigin-RevId: 8944f5a21816a1405e038a0d4c08b66362ea9368
## Why
Extension warnings need a stable thread target even when they are emitted outside an active turn.
## What changed
- Add `ExtensionWarning` and a dedicated `ExtensionEventSink::emit_warning` path with an explicit thread ID and optional turn ID.
- Deliver extension warnings as thread-scoped app-server `warning` notifications, preserving listener ordering and waiting briefly for a subscriber when no listener is active.
- Move skills warnings to the new path, limiting provider catalog warnings to four messages of 256 bytes each.
## Testing
- Cover warning routing, ordering, UTF-8-safe truncation, subscriber fallback, and invalid thread IDs.
- Verify skills warning bounds and app-server delivery of executor catalog budget warnings.
GitOrigin-RevId: 4dcb1ba7f17c0edb1a9d548f9568e0c734bffc15
## What changed
- Record `codex.apps.read.duration_ms` when `app/read` returns a response.
- Tag the duration by the request's `include_tools` value.
- Move the `app/read` handler into its own request-processor module.
GitOrigin-RevId: e1563cd41c72ad03e7f5d5d33cd8a3b35e27984b
## What changed
- Parse the `browser_use.disable_auto_review` setting from layered
`requirements.toml` configuration.
- Return the setting as `browserUse.disableAutoReview` from
`configRequirements/read` and publish it in the generated JSON and TypeScript
schemas.
## Testing
- Add an app-server RPC test covering the Browser Use requirement.
GitOrigin-RevId: 5749d5bc17bcc5b582bf7ed59b8e5b72d6c8f7fc
## Why
Paginated threads allow only one app-server process to write at a time. Archive and delete operations must not mutate a thread or its spawned descendants while another process owns any of them.
## What changed
- Acquire paginated writer locks for the full archive or deletion set before changing rollout files, including descendants whose rollout has not materialized yet.
- Add a batch archive store operation so ownership conflicts are detected before any thread in the subtree is archived.
- Return ownership conflicts as JSON-RPC invalid-request errors and document the behavior.
## Testing
- Cover archive and deletion conflicts for owned threads and descendants, including unmaterialized rollouts.
- Verify deletion still removes rollouts with unreadable metadata.
GitOrigin-RevId: f62a3e0c1ee2631cea48dd9145b588a1486e2425
## Why
The snapshot-backed `apps/installed` duration metric needs dimensions that can
be compared with the legacy `app/list` baseline.
## What changed
- Label snapshot-backed duration samples with `path=installed` and add the
legacy-compatible `reload` dimension alongside the detailed refresh fields.
- Record duration samples only for successful responses so failed requests do
not enter the success latency distribution.
## Testing
Added unit coverage for the duration metric dimensions on refreshed and
non-refreshed requests, and for omitting samples on failed requests.
GitOrigin-RevId: 0755dcaaa94f1d973adfc62a27ea97e3e01edc8b
## Why
Persisted item snapshots can be updated after their initial projection while retaining their creation order. Callers need a way to read those updates incrementally without replaying every item.
## What changed
- Track the rollout ordinal of each item's latest snapshot separately from its creation ordinal.
- Let thread-store callers filter items after an exclusive update watermark and sort pages by either creation or update ordinal.
- Keep existing app-server reads creation-ordered, reject incremental reads across forked lineages, and preserve compatibility with older writers.
## Testing
- Cover update-watermark filtering, pagination, sort directions, per-turn reads, cursor validation, forked lineages, migration compatibility, and refreshed item snapshots.
GitOrigin-RevId: d57de849abec27f788e9c384dbff073a0aca1053
## What changed
- Add nullable `iconSmallUrl` and `iconLargeUrl` fields to the v2
`SkillInterface` protocol and generated schemas.
- Populate the fields from remote plugin catalog metadata while returning null
values for local skill interfaces.
- Document the new `plugin/read` response fields.
## Testing
- Extend the remote `plugin/read` test to verify both icon URLs are returned.
GitOrigin-RevId: 0a631a0121627d944a84e542728a506823ff2738
## What changed
- Wrap `CodexErrorDetails` and an optional retry delay in `CodexErr`, allowing any mapped error to preserve server-provided retry timing.
- Generate the payload-free `CodexErrKind` classification alongside the error details and reuse it for analytics.
- Update error handling sites to inspect `CodexErr::details()` while preserving existing display, debug, protocol mapping, and retryability behavior.
## Testing
- Add coverage for legacy debug formatting, error-specific retryability, and retry-delay propagation through API error mapping.
GitOrigin-RevId: d3ab8a305f2a2ee21d0c0a8c8c388b06dda9c59a
## Why
Only one app-server process should keep a paginated thread open for writing at
a time, while other processes must still be able to read it.
## What changed
- Acquire a per-thread filesystem lock when creating or resuming a paginated
thread, and retain it for the lifetime of the live recorder.
- Reject a competing `thread/resume` request with JSON-RPC error `-32600` and
release ownership when the writer is discarded, deleted, or shut down.
- Remove stale lock files without disturbing active writers.
## Testing
Added coverage for competing processes, ownership transfer after shutdown,
stale-lock cleanup, and lock release during discard and deletion.
GitOrigin-RevId: 81d49a2fffc73ba8135752b4944f27feafa4c0d6
## Why
Refreshing MCP runtime state should not restart an unchanged, ready server or
relist its tools.
## What changed
- Reconcile refreshed MCP configuration against the published connection set
and reuse connections whose transport, environment, authentication, OAuth
credentials, and client capabilities are unchanged.
- Keep tool filters, timeouts, metadata, and plugin provenance in the published
server view so those settings can change without reconnecting.
- Update elicitation authority in place for reused connections, and reconnect
when connection-defining inputs or live OAuth credentials change.
## Testing
Added coverage for unchanged-server reuse, view-only and elicitation-policy
updates, connection identity changes, OAuth credential changes, and avoiding
redundant tool listing.
GitOrigin-RevId: f04f5db5fbdde127b6a14f6aa9673112c0b557e7
## What changed
- Treat batch writes containing only `model`, `model_reasoning_effort`,
`plan_mode_reasoning_effort`, `service_tier`, or `personality` as defaults for
future sessions, even when `reloadUserConfig` is requested.
- Keep runtime config reloads and skill/plugin cache invalidation for other
config changes, and document which settings remain session-static.
- Preserve cached skill listings after session-default writes until a forced
reload, with test coverage for each supported default.
GitOrigin-RevId: 6d988014cf4758ceb9422a11f7c2bd5fc6b9f90a
## What changed
- Make `McpRuntime` own the published MCP configuration, connections, elicitation routing, and selected capability roots for a thread.
- Capture immutable MCP bindings for model steps and tool calls so in-flight work keeps a consistent connection set and approval authority while refreshed state is published atomically.
- Mark MCP state dirty when relevant configuration, plugins, environments, authentication, or elicitation capabilities change, then rebuild it before the next sampling request or out-of-band MCP operation.
- Separate config reloads from server invalidation: `ReloadMcpConfig` applies resolved MCP inputs, while `RefreshMcpServers` requests reinitialization from the thread's latest state.
## Testing
- Cover refreshed state visibility for existing turns, stable step bindings, current approval authority, cancelled refresh retries, resource-client reconciliation, and Apps recovery between sampling requests.
GitOrigin-RevId: 59eabb1aa8dc083426bd18ef4d3630508f376401
## What changed
- Make `plugin/list` requests with `forceRefetch: true` wait for configured
local plugin caches to finish reconciling before building the response.
- Track marketplace plugin sources when deduplicating refreshes so source
changes can trigger a reinstall even when the plugin version is unchanged.
- Notify effective-plugin consumers when the awaited refresh changes the cache.
## Testing
Added coverage showing that a forced local plugin listing returns an upgraded
plugin from the same marketplace path only after the new version is installed
and the superseded cache entry is removed.
GitOrigin-RevId: c1b59f3be6cc19dac8db39aaea548ddf8e342f1d
## What changed
- Load app metadata for plugin read and install responses through the authenticated batch API, splitting requests into batches of 100 and retaining cached metadata if a batch fails.
- Preserve every declared app in plugin responses, using its ID as the fallback name and retaining categories from the plugin declaration when metadata is unavailable.
- Add `isEnabled`, `disabledReason`, and `isReadOnly` to `AppToolSummary`, with defaults that keep legacy responses compatible.
## Testing
- Cover plugin reads with more than 100 apps, partial batch failures, install-time authentication results, tool-state propagation, and legacy tool summaries.
GitOrigin-RevId: 14000df9c5c94dde781358e292a8bef741c5dd23
## What changed
- Cache global, user, and workspace remote plugin catalogs on disk with a three-hour TTL and scope- and account-specific keys.
- Serve cached catalogs from `plugin/list`, refresh stale entries in the background, and warm existing caches at app-server startup without blocking list requests.
- Make `forceRefetch: true` bypass cached catalog data and replace an entry only after a successful fetch.
- Invalidate user and workspace catalog caches after remote plugin sharing changes.
## Testing
- Cover cache freshness, scope isolation, legacy global cache compatibility, identity requirements for private catalogs, forced refetches, and non-blocking startup refreshes.
GitOrigin-RevId: 7844e9dfb72e43b26d749b4afd16fd9c1793caba
## What changed
- Add the `supports_standalone_web_search` model-provider setting, defaulting to `false`, and preserve it in remote thread configuration.
- Enable the standalone `web.run` tool for opted-in custom Responses providers when web search is enabled and the runtime provider supports it.
- Send standalone search requests through the custom provider's endpoint and authentication.
## Testing
- Cover opt-in, default-off, disabled-search, and unsupported-provider behavior.
- Verify custom-provider search request routing and authorization through the app server.
GitOrigin-RevId: 7c5f96b0ce924ad2b9715c45bfc635e89fc39cff
## What changed
- Add `isPinned` to thread responses and allow `thread/metadata/update` to pin or unpin stored threads.
- Add an `isPinned` filter to `thread/list`, including cursor-based pagination and combinations with relationship filters.
- Persist pin state in SQLite without modifying rollout files, default existing threads to unpinned, and preserve pins through reconciliation and archive transitions.
## Testing
- Cover protocol serialization, database migration and indexing, pin updates, filtered pagination, rollout reconciliation, and archive/unarchive behavior.
GitOrigin-RevId: c2eacabd6dae465e2ae6ce8a169e00740960cdb7
## What changed
- Route realtime V3 `bemTags` handoffs using `[ANALYSIS]`, `[COMMENTARY]`, and `[FINAL]` prefixes by default.
- Add `codexResponseHandoffChannelPrefixes` to realtime start requests so clients can replace the accepted prefixes for individual channels. Each channel may accept multiple prefixes, and omitted channels retain their defaults.
- Apply the configured prefixes to both complete and streamed handoff messages, without treating empty prefixes as matches.
## Testing
- Cover request deserialization, default and custom routing, partial streamed prefixes, empty-prefix handling, and end-to-end V3 handoffs.
GitOrigin-RevId: d0aef50aa71362a5beef2c6f6d28b8633da4e529
## What changed
- Add `StartThreadOptions::new` to provide the standard configuration for a new thread.
- Make `ThreadManager::start_thread` the single thread-start entry point and migrate callers from the previous convenience methods.
- Derive default environment selections when `environments` is `None`, while preserving explicit selections, including an empty list.
GitOrigin-RevId: 8977dc11aed54c5e1215a81eaed2b2cf5fc6087a
## What changed
- Add the disabled-by-default, under-development `mcp_2026_07_28` feature.
- Include the feature in the configuration schema and app-server experimental
feature enablement API.
GitOrigin-RevId: 869835ee72f063d79ca2ecd9f2655d2efc457292
## What changed
- Use `McpConnectionSet` as the primary name for the collection of active MCP
server connections throughout `codex-mcp` and its callers.
- Keep `McpConnectionManager` as a backward-compatible type alias.
GitOrigin-RevId: 9753838b4fd0a0b6429a9c4af0c077137616f388
## Why
Forking a persisted thread could lose its approvals reviewer and fall back to
configuration defaults.
## What changed
- Restore the latest persisted approvals reviewer from the full source history
when creating a fork, while continuing to honor explicit overrides.
- Keep boundary-based history truncation independent from reviewer restoration,
so a fork at an earlier turn retains the source thread's latest setting.
## Testing
- Add an app-server test that sets auto-review, forks at an earlier turn, and
verifies the fork reports auto-review.
GitOrigin-RevId: 41c515755de7de600f71c1259f96908f2d169ca7
## Why
ChatGPT token refresh requests need to follow the same configured routing policy as other authentication traffic, including environments that use the system proxy.
## What changed
- Require an `AuthRouteConfig` throughout login, logout, token refresh, personal access token, and agent identity flows.
- Build auth HTTP clients directly from that configuration instead of falling back to a default HTTP client when routing configuration is absent.
## Testing
- Add an integration test that refreshes a token through a cached system-proxy route and verifies the proxy receives the expected request.
GitOrigin-RevId: 7d54ab3219939a49921c51faf08cd4c2eabca51c
## Why
Auth routing represented the default proxy policy as an absent configuration,
leaving consumers to reconstruct the fallback HTTP client independently. Carry
the application's resolved policy explicitly so auth and related requests use
the same client configuration.
## What changed
- Build `AuthRouteConfig` from the resolved `HttpClientFactory` for both
`ReqwestDefault` and `RespectSystemProxy` policies.
- Pass that route configuration through login, auth, cloud task, and cloud
configuration flows, and reuse its factory when loading cloud configuration.
- Log cloud-task configuration load failures before falling back to the
transport-default proxy policy.
## Testing
Extended configuration tests to verify that effective and bootstrap auth routes
select the expected proxy policy when system-proxy support is enabled or
disabled by feature requirements.
GitOrigin-RevId: d03802e2660f5cf6d940e8e718ec5c82ede7eab1
## What changed
Redirect stdin to null when launching:
- `codex doctor --json` for uploaded diagnostic reports
- Git commands used by `codex doctor`
- ripgrep searches over rollout files
- the Windows sandbox setup refresh helper
This keeps these non-interactive subprocesses from reading Codex's inherited
input stream.
GitOrigin-RevId: 063d191b0b1b849d74b55a7d6ff2f0b3d5212c86
## Why
Default read-only protections for project metadata should apply when paths such
as `.git`, `.agents`, and `.codex` exist, without causing sandbox setup to
materialize missing paths as ACL targets.
## What changed
- Add an optional `missing_path_behavior` to filesystem sandbox entries and
mark default project-metadata protections with `skip`.
- Preserve the behavior through permission transforms and exec/MCP protocol
serialization while keeping existing path wire variants stable.
- Ignore skip-missing entries when projecting configuration or Windows sandbox
overrides, while retaining explicit metadata carveouts.
## Testing
- Cover protocol round trips for path and special-path entries.
- Verify default metadata protections and Windows explicit carveout handling.
GitOrigin-RevId: 6df13dadacdd131c44aab9f15a967c81051355c1
## What changed
- Apply managed values for `sqlite_home`, `log_dir`, `model_catalog_json`,
`check_for_update_on_startup`, `allow_login_shell`, the report-submission
opt-in, and `windows.sandbox_private_desktop` to the runtime configuration,
with source-aware warnings when they override configured values.
- Expose these values through `configRequirements/read`, return them from
`config/read`, include them in session config locks, and show their sources in
the TUI config debug view.
- Reject app-server writes that overlap an exact managed requirement with
`configRequirementReadonly` while leaving unrelated sibling keys writable.
## Testing
- Cover runtime overrides, requirement API mapping, config reads and writes,
session lock serialization, cross-platform path URIs, and debug output.
GitOrigin-RevId: d4e23b6fd7775c1a6dfe2eab313cdcee50b07081
## What changed
- Add the optional `forceRefetch` boolean to `PluginListParams` and generated schemas.
- Accept both omitted and enabled values without changing `plugin/list` behavior yet.
- Cover deserialization of the enabled value in the protocol tests.
GitOrigin-RevId: fd4145161e9779638bc0bf18118d5ab5b8478745
## Why
Paginated forks can retain a `history_base` pointer to another rollout. Deleting or compressing either side of that relationship can leave the fork without the rollout history it references.
## What changed
- Add a rollout reference index that scans active, archived, and compressed rollout metadata.
- Reject deletion when a rollout is still referenced by a fork outside the requested deletion set.
- Delete spawned thread subtrees as one store operation so internal references do not block deleting the complete subtree, while external references preflight the request before any files are removed.
- Skip referenced rollouts, fork-pointer rollouts, and rollouts with unreadable metadata during background compression.
## Testing
- Cover reference indexing across active, archived, compressed, duplicate, and self-referencing rollouts.
- Verify deletion rejects external references without partially deleting a subtree and permits batch deletion of internally referenced threads.
- Verify compression preserves fork pointer chains and continues past unreadable metadata.
GitOrigin-RevId: a8672727f8706e743d7fb3ca895a1d9ceac98a3c
## 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.

## 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.

## 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.

## 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.
