## Why
Background terminal working directories can use a path convention from a
different platform than the app-server host. Converting them to host-native
absolute paths can reject otherwise valid terminal entries and fail the list
request.
## What changed
- Represent `ThreadBackgroundTerminal.cwd` with `LegacyAppPathString` at the
protocol boundary.
- Convert terminal `PathUri` values directly to their inferred native path
strings instead of validating them against the host platform.
## Testing
Add protocol round-trip coverage for POSIX, Windows drive, and Windows UNC
working directories.
GitOrigin-RevId: d766d54bdc191e75955fb419bec6e60c65f52298
## What changed
- Add the stable, disabled-by-default `recommended_plugins` feature flag.
- Load recommended plugin candidates when apps and plugins are enabled and
either `tool_suggest` or `recommended_plugins` is active.
- Keep the `request_plugin_install` tool gated by `tool_suggest`.
## Testing
- Cover the first turn after external login with `tool_suggest` both enabled
and disabled, including the expected install-tool availability.
GitOrigin-RevId: 06d9a1c2e8dd2498a47796d833eb6d25ba528351
## What changed
- Add nullable `disabledReason` and `eligiblePlanTypes` fields to v2
`PluginSummary` responses and generated schemas.
- Preserve the remote catalog values across discovered, installed, and cached
plugin summary paths while returning `null` for local plugins and older
remote responses.
- Treat unrecognized disabled reasons as `unknown` for forward compatibility.
## Testing
- Cover protocol round trips, remote summary propagation, unknown disabled
reasons, and app-server responses for admin-disabled and plan-ineligible
plugins.
GitOrigin-RevId: 657a7ea6f838a6ff8bd1769ebcca0f3432684437
## What changed
- Require callers to provide an HTTP client for MCP OAuth discovery and login, removing the separate direct `reqwest` path.
- Use the shared `http` and `url` types throughout the MCP client and drop its direct `reqwest` dependency.
- Preserve configured MCP headers when routing OAuth discovery through the provided client.
## Testing
- Add coverage that routed OAuth discovery forwards configured headers.
GitOrigin-RevId: 1345f56bd794626533133447597a5908e57b9b48
## What changed
- Read the selected turn's `model` and reasoning `effort` from its rollout and add them to the report's upload tags.
- Use the latest turn context when the request has no `turn_id`, without substituting another turn when a requested ID is missing.
- Prefer the request-derived model and effort over values captured in the report snapshot.
## Testing
- Added coverage for selecting a reported turn, falling back to the latest turn, handling a missing turn, preserving an unspecified effort, and upload-tag precedence.
GitOrigin-RevId: 133bab7730e18b28c4b26ae55fbce55d8e5705fb
## What changed
Update the existing-thread curated MCP sync test to wait for each server's
`ready` startup notification before proceeding through refresh boundaries or
calling the synced server's tool.
GitOrigin-RevId: 56fd7ff72ff277a043c4a2d8168079da053b4829
## What changed
- Recognize `self_serve_business_prolite` across authentication, account and rate-limit APIs, generated schemas, workspace classification, status display, cloud configuration gating, and usage-limit messaging.
- Keep the Python SDK's `PlanType` enum compatible with non-empty string values introduced by newer Codex runtimes while preserving its known constants.
## Testing
- Cover token parsing, account reads and notifications, backend rate-limit mapping, workspace behavior, error formatting, and Python SDK response coercion for the new plan value.
GitOrigin-RevId: 70bc17a7c4ba4028cb10e4333cc1f2ac64da361f
## What changed
- Replace the `isPinned` thread metadata and filters with an optional persisted
`section` and `sectionId`.
- Add the paginated `threadSection/list` app-server method so clients can
discover sections even when they contain no threads.
- Seed a stable `Pinned` section, validate section assignments, and support
filtering for a specific section or for unsectioned threads.
## Testing
- Cover section protocol serialization, listing and pagination, metadata
updates, filtering, persistence, migration compatibility, and operation
without SQLite state.
GitOrigin-RevId: 7972b5471d29317b9387bfd90aa9f573f691ad4c
## What changed
- Update the `rmcp` model and transport integrations for `3.0.0-beta.3`.
- Preserve legacy `elicitation/create` form requests, schema defaults, metadata, and wire-format compatibility while adopting the new elicitation types.
- Harden OAuth discovery by using GET-first discovery without starting an MCP session, preventing cross-origin header redirects, validating authorization-server and callback issuers, and retaining compatibility with metadata that omits an issuer.
- Keep stored OAuth credentials readable and avoid requiring reauthorization after transient refresh failures.
## Testing
- Add coverage for legacy elicitation round trips, OAuth discovery variants, callback issuer validation, credential migration, and refresh failures.
GitOrigin-RevId: 756197d26f3fd347c28c400228f6b3d06ed493b7
## What changed
- Add `features.multi_agent_v2.subagent_developer_instructions` to override inherited developer instructions for subagents that do not define role-specific instructions.
- Preserve role-specific instructions as the higher-precedence setting, and carry the effective instructions through full and bounded forks, compacted histories, and cold resume without duplication.
- Treat an unset override as inheritance and a blank override as clearing inherited instructions.
## Testing
- Cover configuration parsing and materialization, instruction precedence, fork modes, compaction, role application, and resumed subagents.
GitOrigin-RevId: 32321e61abc59b14a1be5f31e6bd6570bb1cd89d
## Why
Paginated rollout history may contain only a bounded suffix. Deriving display
metadata from that suffix can replace the thread's original preview, title, and
first user message when the thread is read or resumed.
## What changed
- Use SQLite as the canonical source of display metadata for paginated thread
reads, including reads by an explicit rollout path.
- Seed resume metadata tracking from the persisted values so appended history
fills only missing fields instead of overwriting existing ones.
- Prefer an explicitly requested rollout path over a stale path stored in
SQLite while retaining the canonical metadata.
## Testing
Added coverage for reads by ID and path, bounded-history resumes across app
server restarts, preservation of existing metadata, initialization of missing
fields, and stale persisted rollout paths.
GitOrigin-RevId: b393d0727afcba70fda7f50a6f2dcca0632745b4
## Why
Curated plugin capabilities need to follow the active authentication mode, including after an account switch and when the configured model provider differs from the authentication source.
## What changed
- Select the ChatGPT, remote, or API curated marketplace from the current authentication mode, with an API marketplace fallback for ambient Amazon Bedrock credentials.
- Apply that selection consistently to plugin loading, hooks, skills, installed-plugin conflict filtering, marketplace listing, and `codex mcp` discovery.
- Start the local curated repository sync when an account change makes the remote catalog unavailable, and refresh existing thread MCP runtimes when the effective plugin cache changes.
## Testing
Added coverage for account switches, ChatGPT-authenticated Bedrock sessions, API-key MCP discovery, curated marketplace filtering, hook and skill routing, and existing-thread MCP refreshes.
GitOrigin-RevId: dbefdba3a3ea7281e7b6013e057a418770ccfc95
## Why
`features.multi_agent_v2` can be represented as either a legacy boolean toggle
or a table with an `enabled` field and nested settings. Layering or editing
configs that mix these forms could replace one form with the other and discard
the enabled state or nested settings.
## What changed
- Normalize boolean toggles to the table's `enabled` field when merging config
layers, applying CLI overrides, and editing user or profile config.
- Preserve nested multi-agent settings when toggling the feature, while keeping
ordinary replacement semantics for unrelated paths.
- Attribute normalized `enabled` values to the layer that supplied the boolean
toggle so config write results report overrides correctly.
## Testing
Added coverage for layered config, CLI overrides, config edits, app-server
writes, and origin metadata using both root and profile feature paths.
GitOrigin-RevId: 38b248c949b9ea5d6340a73d754f91c1834ac486
## Testing
- Verify full, compacted, and bounded history forks preserve developer messages while removing stale parent usage hints.
- Add an app-server regression test that cold-resumes a root thread and confirms a roleless worker retains inherited developer instructions when lazily reloaded for follow-up work.
GitOrigin-RevId: 40e454a2a2b721ea645cbc607b17a3ae6b617bd9
## Why
Cursor session messages can place `<cursor_commands>` and `<timestamp>` context
before the actual `<user_query>`. Treating both external session formats with one
parser left that context in the imported message and generated title.
## What changed
- Route detected sessions through format-specific Claude and Cursor parsers.
- Strip recognized Cursor context wrappers when extracting a trailing
`<user_query>`, while preserving messages with unknown leading context.
- Keep shared content-block, tool-call, and timestamp parsing in a common module.
## Testing
Add parser coverage for wrapped Cursor queries, unknown context, working-directory
precedence, Claude metadata, content hashing, and shared tool annotations.
GitOrigin-RevId: b49328d46ab4937e3c599588a3d3081e8ab798cd
## What changed
- Add the stable, default-enabled `in_app_updates` requirements-only feature.
- Allow administrators to disable in-app updates through `[features]` in `requirements.toml`.
- Expose the policy through `configRequirements/read` and include it in the config schema.
## Testing
- Verify that in-app updates are enabled by default and disabled by the managed requirement.
- Verify that `configRequirements/read` returns the configured policy.
GitOrigin-RevId: e9c7074b516fe58385fdf7dc8420c0109c0c3df6
## Why
Detached processor work can retain outgoing message senders, so waiting for
channel closure can keep the in-process app-server's outbound router alive
during shutdown.
## What changed
Add an explicit shutdown signal for the outbound router and prioritize it over
pending outgoing messages. Send that signal after processor tasks are stopped
so runtime shutdown no longer depends on every sender being dropped.
## Testing
Add a paused-time test that verifies the router exits and closes its channel
even when an outgoing sender is still retained.
GitOrigin-RevId: a8f88d88a0950f50339b1c56909fedb781f178d4
## What changed
- Set the Rust recursion limit to 256 for both the MCP server library and binary crates.
- Populate `started_at_ms` in the thread-fork test's completed-item fixture.
GitOrigin-RevId: b25eeaeecaf94265fe3be8f23cb3c395595afc2a
## What changed
- Exclude `SkillScope::System` roots from watcher registration because generated
system skills are installed before the watcher starts.
- Ignore events under the system skill cache that arrive through the recursively
watched legacy user-skills root, avoiding unnecessary cache clears and
`SkillsChanged` notifications.
GitOrigin-RevId: ce8ba28ba873372b638950b676e4d09172a5c688
## What changed
- Add an optional `started_at_ms` field to `ItemCompletedEvent`, retaining
compatibility with older persisted events that lack it.
- Track the first start timestamp for each in-flight item and attach it when
emitting and persisting the completion event. If no start was recorded, use
the completion timestamp as a fallback.
- Emit a complete start/completion lifecycle for subagent activity items.
## Testing
- Cover concurrent item timing, repeated starts, turn-boundary cleanup, the
missing-start fallback, subagent activity, and persisted web-search events.
GitOrigin-RevId: e7cec9c4f1ef6ba67f287e81fb4d7d856fcf87a7
## What changed
- Carry a plugin's local and remote identities together from plugin loading into
`SkillMetadata`.
- Resolve remote IDs from the installed-plugin snapshot when available, falling
back to persisted install metadata only when no snapshot exists.
- Include plugin identity in skill cache keys so identity changes refresh cached
skill metadata.
## Testing
- Cover snapshot and persisted identity resolution, local marketplace isolation,
cached skill refreshes, and propagation through plugin skill snapshots.
GitOrigin-RevId: aabeeb631a43361fe817358ace7f1ea8ba5db708
## What changed
- Add nullable `canPublishToWorkspace` metadata to plugin share contexts and `plugin/share/save` responses.
- Preserve the remote capability through catalog parsing and app-server responses so clients can decide whether to offer workspace-directory publishing.
- Document that clients should fail closed when the capability is unavailable.
## Testing
- Cover remote catalog parsing, share-save response propagation, and protocol serialization.
GitOrigin-RevId: b0346b3b330169838f800dfdf21dfa5db1a47f4d
## What changed
- Allow `thread/fork` to create an ephemeral fork from paginated history when
`excludeTurns: true` is set, and return an invalid-request error otherwise.
- Preserve the selected history and fork preview without creating a rollout
path or exposing the ephemeral thread through `thread/list`.
## Testing
- Cover full-history and bounded ephemeral forks, active-turn boundaries,
preview selection, model input, and thread listing behavior.
GitOrigin-RevId: 4c0d9739b3310d7d0d7389bec127045ac4f55b44
## Why
MCP authentication checks need to use the same HTTP routing as the MCP
transport so servers reached through configured proxies can be discovered
reliably.
## What changed
- Resolve OAuth discovery and authentication status through each server's
runtime HTTP client for both local and managed environments.
- Keep local discovery capped at five seconds while allowing explicit login
requests to retain their requested timeout.
- Resolve refreshed MCP configuration and its runtime context from the same
snapshot.
## Testing
- Cover OAuth discovery through an environment proxy and macOS system proxy
resolution.
- Cover proxied MCP startup and runtime refresh with updated authorization
headers.
- Verify capped and preserved OAuth discovery timeout policies.
GitOrigin-RevId: 461fb1d4786e547df8b1e6b2215a8ac40438a3aa
## 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
Executor skills that disallow implicit invocation are omitted from `skills.list`, so an explicitly selected skill did not provide the authority and package identifiers needed to read its referenced resources.
## What changed
- Add `resource_access` metadata to injected instructions for explicit-only executor skills.
- Teach the `skills.read` description to accept that metadata as well as values returned by `skills.list`.
- Keep discoverable executor skill instructions unchanged.
## Testing
Add an app-server integration scenario that selects an explicit-only executor skill, confirms it remains absent from `skills.list`, and reads a referenced file through `skills.read`.
GitOrigin-RevId: 97d3b93d1618c013363788452303c8a31e32cc56
## What changed
- Add executor authority support to `skills.list` and `skills.read` for skills from selected capability roots.
- Allow `skills.read` to load package-relative resources referenced by an executor skill while keeping reads within the selected package.
- Paginate skill listings and resource contents with bounded response sizes and stale-cursor validation.
- Resolve executor filesystems per sampling step so skill tools use the active selected capability roots.
## Testing
- Extend the app-server executor skill test to list an executor skill, read its main `SKILL.md`, and read a paginated reference resource.
- Cover visibility filtering, metadata bounds, pagination, invalid cursors, package boundaries, and resource size limits.
GitOrigin-RevId: 1b5de95d5d1b9f79c34d2879d6e67f24401e9c29
## 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
- Add `--code-mode-host ws://...` and `wss://...` support to `codex app-server`, gated by the `code_mode_host` feature. When omitted, app-server continues to start a local host.
- Share one remote WebSocket connection across the process's threads, using the configured HTTP client's proxy and TLS policy and preserving the existing framed host protocol.
- Reject invalid host URLs, bound WebSocket frame sizes, close connections cleanly, and return an error when a connection exceeds 1,024 pending delegate calls without disconnecting it.
## Testing
- Cover CLI validation, WebSocket protocol execution and shutdown, connection sharing across app-server threads, and delegate-call capacity recovery.
GitOrigin-RevId: 715e82d4d9db1e7e2f91b754a777dcab504e2ae4
## 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
## What changed
- Add optional `plugin_id` and `script_path` fields to execution approval and guardian assessment events.
- Propagate validated plugin attribution through delegated approvals, guardian-reviewed command items, app-server notifications, thread history, and rollout traces.
- Preserve attribution on both started and completed command items, including declined commands.
## Testing
- Extend core, app-server, thread-history, and rollout-trace tests to cover plugin attribution propagation and serialization.
GitOrigin-RevId: 723684d010cab04142918d7a95e06ed95d008da1
## Why
Delegated HTTP requests need to honor the same outbound proxy policy as the
Codex process that starts the exec server.
## What changed
- Pass the configured `HttpClientFactory` through local and remote exec-server
startup and use route-aware client pools for delegated HTTP and local MCP
requests.
- Preserve per-request timeouts and follow-or-stop redirect behavior while
keeping request URLs and sensitive response headers out of diagnostics.
## Testing
- Cover configured system-proxy routing across the exec-server transport.
- Cover both redirect policies and verify that success and failure logs do not
expose request or response secrets.
GitOrigin-RevId: 4af6aec1d265c4db62dfcb6e1fb076fb31736137
## What changed
- Resolve shell and unified-exec commands against the trusted plugin roots loaded for each turn.
- Add optional `pluginId` and safe plugin-relative `scriptPath` fields to command execution items and legacy execution events, and propagate them through app-server notifications.
- Include the attribution in command execution analytics while rejecting absolute, unsafe, and unattributed script paths.
## Testing
- Cover attribution for cached curated and remote plugin scripts from command execution through core and app-server events.
- Verify analytics serialization and unsafe-path filtering.
GitOrigin-RevId: 02fac3a233284ccfc6642fa502a95f1881dba83d
## 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
The TUI must inspect the default execution environment before loading its final
configuration. Initializing the environment manager at that point can give
startup services the bootstrap HTTP policy instead of the effective policy after
managed requirements are applied.
## What changed
- Split environment discovery from manager construction so callers can inspect
the default environment without starting remote connections.
- Build the environment manager after final configuration loading and pass its
resolved `HttpClientFactory` through all construction paths.
- Add shared test support for managers that use the legacy default HTTP policy.
## Testing
- Cover connection-free environment discovery and explicit HTTP policy
propagation.
- Verify TUI startup services use the final managed `respect_system_proxy` value.
GitOrigin-RevId: 928fa31e6b4bcfbe1a121cade2f351427fdfa0f4
## Why
Codex and SQLite data can use separate home directories, but state consumers
could reconstruct database paths from the Codex home instead of consistently
using the resolved SQLite configuration.
## What changed
- Pass `SqliteConfig` through the core, rollout, state runtime, and thread store
instead of passing a directory and rebuilding the configuration downstream.
- Use that shared configuration for state, logs, memories, goals, and paginated
thread-history database access, including integrity checks and cleanup.
- Reject state database handles whose SQLite configuration does not match the
requesting store.
## Testing
Add coverage with separate Codex and SQLite homes that verifies startup
backfill, thread listing, and paginated history all use the configured SQLite
directory.
GitOrigin-RevId: 1de1cdd1d6ff1d70bbb6c360c8352e6543fb8ebf
## Why
Imported sessions previously used the import time for their thread metadata,
discarding the chronology recorded by the source session.
## What changed
- Set `created_at` and `updated_at` from the earliest turn start and latest turn
completion timestamps in the imported rollout.
- Use the latest source timestamp for thread recency, while retaining the current
time as a fallback when the rollout has no valid turn timestamps.
## Testing
- Update the external agent import integration test to verify the persisted
creation, update, and recency timestamps.
GitOrigin-RevId: 396d5b7e7463a305a5a828ba3a432b4a97e5d2b9
## 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
Clients that complete an external agent config import outside the app server need a way to include the result in import history.
## What changed
- Add `externalAgentConfig/import/recordHistory` to persist completed item results and return a generated import ID.
- Store the optional provider ID for regular imports and expose it when reading import history.
- Update the generated JSON and TypeScript protocol schemas for the new request, response, and history field.
## Testing
- Cover recording and reading an externally completed import through the app-server protocol.
- Cover provider ID persistence and updates in the state runtime.
GitOrigin-RevId: 935401e899ec9eeb38f54c182e45a16642411deb
## Why
Relative local marketplace paths can contain `@`, but source parsing treated it as a Git ref separator.

## 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.
