## Why
Clients need to list models for a configured provider other than the app-server's startup default.
## What changed
Add an optional `modelProvider` parameter to `model/list` and expose it in the generated schemas and client types. Explicit selections use provider definitions loaded at startup and respect current managed provider requirements. Unknown providers return a structured `modelProviderNotConfigured` error.
Use a temporary catalog when selecting another provider, preserving the default catalog and its disk cache while retaining runtime authentication. Requests without a selector keep the existing provider and caching behavior.
## Testing
Add coverage for provider selection, preservation of the default catalog and disk cache, unknown-provider errors, managed requirement enforcement, and runtime authentication for temporary catalogs.
GitOrigin-RevId: 6092df9f6141810c6ac215a8e1fb601f77e54747
## Why
A network request can disappear while its approval prompt is still pending. Leaving that prompt active allows a late cancellation to interrupt the turn even though the request no longer needs approval.
## What changed
- Track network prompt lifetimes in core and notify the app server when a prompt is resolved or withdrawn.
- Cancel the corresponding server request, emit `serverRequest/resolved`, and release its permission guard. Resolve outstanding network prompts during thread shutdown as well.
- Claim a live pending approval and validate its originating turn before applying a decision, so stale responses cannot interrupt a turn or persist policy changes.
- Distinguish network approvals that require the originating turn from proxy approvals that can be serviced by a later active turn.
## Testing
Extend regression coverage for disconnected network requests, late cancellation responses, turn completion during review, shutdown cleanup, mismatched turn IDs, and command approvals from background code running during a later turn.
GitOrigin-RevId: 78f656d92607ec21ddd0c5d781ed0947588cb2eb
## What changed
`review/start` now supports only inline reviews on the supplied thread and returns that thread's id as `reviewThreadId`. Clients can omit `delivery`, send `null`, or specify `"inline"`; `"detached"` is no longer supported.
For a separate review thread, call `thread/start` followed by `review/start`. To preserve conversation history with custom review instructions, use `thread/fork` followed by `turn/start`.
Remove detached review execution and its app-server dependency on `codex-agent-extension`, and update the protocol schemas and generated clients. Preserve `ReviewDelivery.inline` as a Python enum member.
## Testing
Add a Python regression test verifying that inline review delivery parses as `ReviewDelivery.inline` and round-trips to the original JSON.
GitOrigin-RevId: ed16c5271c3315ae3afcb3ee78883ed421394b4d
## What changed
- Add an optional `name` to `AdditionalContextEntry` across the protocol, app-server schemas, and generated clients.
- Accept names matching `[a-z][a-z0-9_]{0,63}` only for `untrusted` context. Reject invalid names and names on `application` context before admitting turn input, returning invalid-request errors from `turn/start` and `turn/steer`.
- Preserve existing model-input rendering and deduplicate context when only its name changes.
## Testing
Add coverage for valid name boundaries, callers that omit `name`, invalid-name rejection without admitting input, and deduplication across name changes.
GitOrigin-RevId: 2caffa6fddd40ddb178733b335f520f317239edd
## What changed
- Add nullable `startedAtMs` and `completedAtMs` fields to `ThreadItem` in live notifications and turn history. Values are Unix milliseconds when recorded.
- Preserve recorded item times through history reconstruction, pagination, and resume, including command start times recorded during approval.
- Separate the Rust item payload into `ThreadItemPayload` while keeping the JSON payload flat, and update consumers, schemas, and generated TypeScript and Python types.
## Testing
Extend coverage for timestamp serialization, history reconstruction, paginated reads and resume, and persisted Python SDK items.
GitOrigin-RevId: ecbcee95af52db7c807b46a6e9deb30e5fba1f80
## What changed
Add `thread/memory/read` to return `{summary}` for a thread that has been started or resumed. Read `memory_summary.md` from the thread's resolved memory version, honoring thread-specific configuration overrides without falling back to another version.
Return `null` when memory use is disabled or the selected summary is missing, unreadable, or blank.
## Testing
Extend app-server integration coverage to check explicit and automatic memory version selection, disabled memory use, and missing summaries without fallback.
GitOrigin-RevId: b218f31e379c69ccbacb444bb9d6ee920cd4882b
## What changed
Add `codex app-server --print-startup-config` to validate local and cloud-backed configuration and emit the app-server version and configuration requirements as JSON without initializing environments, thread storage, or plugins. Configuration failures produce structured JSON errors and a nonzero exit status.
Support `--startup-sign-out` to remove account credentials and reload signed-out requirements, including recovery when cloud policy is unavailable. Reject sign-out for host-owned external authentication. Accept `--startup-client-info` to identify configuration and authentication requests.
Reuse configuration loading and account cleanup logic between startup discovery and the running app server.
## Testing
Add CLI integration coverage for configuration validation, project login restrictions, managed cloud requirements and failures, sign-out recovery, external authentication protection, and independence from locked or invalid history databases.
GitOrigin-RevId: 636ccb095b684b6136cf9e408f3f8613cb776e16
## What changed
Add `thread/items/read` to retrieve persisted items by `threadId`, `turnId`, and 1–100 `itemIds`. Return matching items in canonical stored order, omitting missing IDs and items outside the requested turn.
Add item ID filtering to the thread store while preserving inherited history and fork cutoffs. Require the experimental API capability for the new endpoint.
## Testing
Add coverage for stored ordering, turn scoping, missing IDs, request size limits, experimental capability gating, and inherited items across fork cutoffs.
GitOrigin-RevId: 9b243dd87577bd4fe36900c388a386b2e26ff2e0
## What changed
- Add experimental `readState` to `thread/read` and a thread-ID-keyed `readStates` map to `thread/list` for eligible durable local user threads. Each receipt contains `firstUnread` and an opaque `revision`.
- Publish new visible terminal results before `turn/completed`, after flushing the rollout. Reading snapshots leaves activity unread; replayed history does not publish new activity.
- Clear unread positions removed by a paginated thread revert while preserving explicit thread-start marks and concurrent receipt updates.
## Testing
Add an integration test covering completed-turn receipts, repeated reads without acknowledgement, matching list receipts, and revert cleanup with a changed revision.
GitOrigin-RevId: e7f6ddfbb1fc2fa95d1ef2876d7f0f7b9f99ff65
## Why
Persisted multi-agent v2 children created after the client disconnects need lifecycle listeners so their runtimes can be released once idle. Listener attachment must also wait for an earlier runtime's cleanup to finish.
## What changed
- Start lifecycle listeners for persisted v2 children even when no initialized clients are connected, and defer attachment until pending unload cleanup completes.
- Keep ephemeral children loaded so follow-up tasks retain their model context.
- Raise the default `thread_unload_delay_secs` from 60 seconds to 1800 seconds (30 minutes), updating the configuration documentation and sample.
## Testing
Add regression coverage for children spawned after disconnect with zero- and one-second unload delays, including waiting for pending cleanup, keeping running threads loaded, releasing idle runtimes, and preserving an ephemeral child's earlier reply across a follow-up. Update configuration tests for the new default and explicit overrides.
GitOrigin-RevId: 2fecc77b5c03237aa8fd7eacc4bd119b99d36e0a
## What changed
Add `TurnEnvironmentRequests` to carry environment requests together with their fallback working directory. Update thread settings overrides and active turn settings to accept requests, constructing `TurnEnvironmentSelection` values in the receiving thread before validation and runtime use.
Adapt app-server callers, reviewer settings, and existing tests to supply requests or explicitly convert runtime selections back into requests.
GitOrigin-RevId: 8028f804bebe3fde553f57bb450f6dca3970cc4a
## What changed
Introduce `TurnEnvironmentRequest` for caller-supplied environment input and construct `TurnEnvironmentSelection` at session startup and app-server settings boundaries. Update thread startup, default environments, and inherited environment handoffs to use requests, with explicit conversions when reusing runtime selections.
Move the environment types into `protocol::environment` while retaining their `protocol` re-exports. Update test fixtures and existing tests to build request inputs separately from runtime selections.
GitOrigin-RevId: 12e7daaece95aae136afae8b055b4dbaebdffc75
## Why
Paginated history previously persisted completed commands' full `aggregated_output`, allowing large command outputs to inflate stored history.
## What changed
- Limit persisted command `aggregated_output` to 64 KiB, including a truncation marker. Preserve the beginning and end of the output without splitting UTF-8 characters.
- Apply the shared persistence policy to rollout recording, thread-store appends, and legacy-to-paginated history migration.
- Measure persisted payload bytes after truncation so persistence metrics reflect the stored representation.
## Testing
Add coverage for the byte limit, UTF-8 boundaries, unchanged inputs that fit, and markers that exceed the budget. Verify capped output in paginated thread history and migrated legacy history, and verify persistence metrics use the truncated payload size.
GitOrigin-RevId: 01d420d396ad34b42dc5dc208c0bf88d890639ee
## Why
Reloads can reject a valid thread configuration when the host configuration references a missing model provider that thread overrides replace. Concurrent cloud refreshes can also leave older policy snapshots or staged cache writes eligible for publication.
## What changed
- Compose preserved session layers before materializing refreshed configuration, retaining source-aware validation errors.
- Carry cloud policy revision bindings through config loading and role overrides. Reject stale MCP refreshes and disable enterprise MCP authorization when the policy is suspended. Retire the old policy when replacing or clearing its loader.
- Stage cloud cache writes in temporary files and publish them atomically only while their policy revision remains current.
- Route file reloads through the shared runtime refresh path, resolve paths relative to each config file, and preserve session settings. Restore host defaults for `secret_auth_storage` and `mcp_oauth_refresh_coordination` when explicit overrides are removed.
## Testing
Add regressions for thread-provided model providers, managed plugin and feature requirement refreshes, stale and suspended policy snapshots, superseded and retired cache writes, and file reloads preserving runtime settings and restoring feature defaults.
GitOrigin-RevId: 3280a2445eeb7074a142f720690bb0e4f01d174b
## What changed
Allow `cursor` to accept an item anchor such as `{"type":"item","itemId":"item-123"}` with a non-empty `turnId`. Ascending pagination returns items after the anchor; descending pagination returns items before it. The anchor itself is excluded, and subsequent pages use the returned opaque string cursor.
Resolve anchors within the requested turn's visible history, including inherited fork history. Reject missing turn IDs and empty, unknown, or out-of-scope item IDs with invalid params (`-32602`). Preserve existing string and null cursor behavior, and update the protocol schemas, TypeScript and Python types, and API documentation.
## Testing
Add protocol round-trip and invalid-shape tests, app-server coverage for anchored pagination and errors, and thread-store coverage for growing turns, reverse pagination, page boundaries, fork visibility, and anchor scope validation.
GitOrigin-RevId: a74cea190d3ff1b44865429f8b0650b793eb688d
## Why
Selected rollouts can reference history stored in ancestor rollouts through `history_base`. Attaching only the selected files leaves that inherited history out of diagnostic reports.
## What changed
When `include_logs` is enabled, follow nested `history_base` references and attach ancestor prefixes up to the recorded byte offsets. Deduplicate ancestors, retain the largest requested prefix, and skip rollouts already selected for upload.
Bound discovery to 64 ancestors and five seconds, and enforce attachment size limits. Missing, unreadable, or incomplete ancestor prefixes are best effort and do not prevent the report upload.
## Testing
Add a unit test verifying that nested parent and grandparent history bases are attached with the expected filenames and contents.
GitOrigin-RevId: d9bba3e50573d25843d2eaedeae775946223ed0e
## What changed
- Add `environments` to `TurnSettingsUpdate` to replace the selection for subsequent steps without changing future turns.
- Capture model settings and environments together so combined updates apply or reject atomically, while existing steps retain their captured selection.
- Validate environment IDs, working directories, configuration ownership, and permission requirements against the running turn's selections.
- Preserve executor startup behavior when switching environments and use the step's local working directory for tool hooks.
## Testing
Add coverage for workspace switching and restoration on the next turn, atomic model and environment updates, permission validation, executor connection waits, and replacement of pending environment selections.
GitOrigin-RevId: 02b5c57a78fd594b2aed84fc09d9e99eb97be28c
## What changed
Add `rollout/compress` to trigger a best-effort background compression pass for cold local rollouts, even when `features.local_thread_store_compression` is disabled. The method takes no parameters and immediately returns `{}` to acknowledge scheduling, not completion. Existing worker locks, concurrency limits, and cooldowns still apply.
Require the `experimentalApi` capability and reject non-local thread stores. Document the endpoint and the requirement that clients sharing the Codex home support compressed rollout files.
## Testing
Add integration tests for compression with the startup flag disabled, lossless rollout readback, experimental capability enforcement, and rejection of non-local thread stores.
GitOrigin-RevId: be73a3b3f37f3adc54512de8256abf684d5d8112
## What changed
Remove `thread/rollback`, its request and response types, generated bindings, and the core `Op::ThreadRollback` operation. Requests now follow the generic unknown-method rejection path. Document `thread/revert` as the alternative for paginated threads.
Keep historical `ThreadRolledBack` markers and legacy error deserialization so existing rollouts remain compatible with replay and migration.
## Testing
Adapt retained-context and Guardian history tests to append legacy rollback markers and resume threads, preserving coverage of surviving instructions, answers, and review history.
GitOrigin-RevId: b3da1becdf86b1869275aacb0ffc2817cee5af2e
## What changed
- Add `thread/attachment/add`, `thread/attachment/list`, and `thread/attachment/remove` to manage durable resource references without loading the owning thread or changing conversation history.
- Identify attachments by thread, `attachmentType`, and `identityKey`. Repeated adds return the existing attachment; repeated removals succeed without emitting another update. Listing supports cursor pagination.
- Broadcast `thread/attachment/updated` after creation or deletion, after responding to the requester. Serialize attachment mutations with thread lifecycle operations and reject stores that do not support attachments.
- Update protocol schemas, TypeScript and Python bindings, documentation, and TUI notification handling so attachment updates do not add untracked threads to the agent picker.
## Testing
Add coverage for unloaded threads, pagination, idempotent addition and removal, reattachment, invalid inputs, unsupported stores, response-before-notification ordering across clients, and TUI notification routing.
GitOrigin-RevId: 0d29cf903afd4e931a70a9cf96300475213b34aa
## Why
Saved threads need to resume after a managed daemon restart so active goals can continue without waiting for a client to reconnect.
## What changed
- Consume the recovery snapshot at startup and restore threads in the background through the shared cold-resume path.
- Trigger idle lifecycle work without attaching a client subscription, and leave already-loaded threads untouched.
- Continue recovery after individual thread failures and abort background recovery during shutdown.
## Testing
Extend the daemon restart integration test to verify goal continuation before client reconnection, restored conversation history and tools, idle-thread restoration, and recovery snapshot consumption. Include malformed snapshots and an invalid thread ID.
GitOrigin-RevId: 90e7b8f74ddc0ae327bacde1b2108b9749c65f2a
## Why
Allow v2 memories to build in the background while the selected memory version continues supplying context, and let clients check whether v2 has enough consolidated data and a valid summary to use.
## What changed
- Add `memories.dual_write`, disabled by default, to run v1 and v2 extraction and consolidation concurrently with separate stores and directories.
- Add the experimental `memory/status` endpoint, returning `v2ConsolidatedThreads` and `v2Ready`. Readiness requires a valid v2 summary and a consolidation thread count meeting `minConsolidatedThreads` (default 20, supported range 1–4096).
- Persist the largest thread count from a successful consolidation across pruning and clear it on memory reset.
- Share v2 summary validation between consolidation and status reporting, and tag memory metrics with `memory_version`.
## Testing
Add tests for independent dual-write outputs, preserving existing notes without importing them into v2, and readiness behavior across consolidation ownership checks, missing summaries, configurable thresholds, thread deletion, and memory reset.
GitOrigin-RevId: 54417cc60bf419062401355c0da8c79119995f61
## What changed
- Add the experimental `Thread.environments` field with each selected environment's ID, working directory, and runtime workspace roots.
- Populate the field from live thread state in start, resume, read, list, and unarchive responses. Use `null` for unloaded threads and an empty list when a loaded thread has no environment selection.
- Document that the field reports selection rather than connection status and does not affect executor selection or resume behavior.
## Testing
- Cover selection updates, unloaded and resumed threads, loaded pathless unarchives, and clients that subscribe after environment connection notifications.
GitOrigin-RevId: a6daa06aff7089d7c5a1e4c7d03109b41f12fa3c
## What changed
- Add nullable `model` and `reasoningEffort` fields to the shared app-server `Thread` object and generated schemas.
- Report current settings for loaded threads and the latest persisted settings for unloaded threads across thread read, list, start, resume, rollback, metadata update, and notification paths.
- Keep unavailable legacy or filesystem-only settings nullable, and allow metadata reads without loading a thread or dispatching queued work.
## Testing
- Cover live-setting precedence, persisted settings after restart, null legacy values, and model metadata returned by thread lifecycle operations.
GitOrigin-RevId: 22ebe8a8d1910a820d90a97730d812a00d8c1372
## Why
Reports from a large thread tree can exceed the rollout attachment limit, making
the threads involved in a failed Guardian review harder to diagnose.
## What changed
- Prioritize descendants with retained failed reviews when selecting bounded
report rollouts, while always preserving the reported thread.
- Include each selected thread's available Guardian trunk rollout alongside its
conversation rollout.
- Add a thread index attachment with selected filenames, bounded omission details,
retained failure threads, and the process-wide discarded-record count.
- Link failed-review records to their reviewed turn and target item when available.
## Testing
- Cover failed-review prioritization, bounded omission metadata, discarded-record
accounting, and turn/item linkage in Guardian report records.
GitOrigin-RevId: ae7916c27a3c279e899cd5a6ead8a4b7e0cc26a1
## What changed
- Add the experimental `turn/settings/update` method for changing `model`,
`effort`, `summary`, and `serviceTier` on a specific live turn without
changing future turns.
- Report whether the update was applied or the target turn was unavailable,
and reject unsupported fields, disabled feature use, unsafe model changes,
and direct updates to parent-owned subagents.
- Document the method's feature requirements, null handling, and limits.
## Testing
- Cover current-turn and future-turn isolation, rejected and unavailable
targets, feature and capability gates, saved threads, and subagent ownership.
GitOrigin-RevId: 18440f6d7ee5fcd06ae23bd41b22c492b62bb2b5
## Why
Clients need a bounded view of realtime conversations that preserves the order of speech, agent work, and turn lifecycle events without loading the full thread history.
## What changed
- Persist realtime session boundaries, transcript segments, and promoted agent items in paginated thread rollouts.
- Add the experimental `thread/timeline/list` API to page ordinary items, realtime items, and turn boundaries in canonical rollout order. Include `activeRealtimeSessionAtPageStart` so each page can be rendered independently.
- Emit typed `thread/realtime/item/started`, `thread/realtime/item/transcript/delta`, and `thread/realtime/item/completed` notifications around durable realtime items.
- Keep the existing `thread/items/list` response and legacy thread history behavior unchanged.
## Testing
- Cover mixed timeline pagination, realtime-session state at page boundaries, rollout replay, subagent history prefixes, transcript streaming, steering, and promoted agent artifacts.
GitOrigin-RevId: faa2c420192d63e060e8fb32446e3c797422656e
## Why
Parent-owned Multi-Agent V2 subagents must remain controlled by their parent,
but several app-server endpoints could still mutate them directly.
## What changed
- Centralize the direct-input ownership check and apply it to turn injection,
MCP calls, reviews, compaction, rollback and revert, shell and Guardian
actions, realtime requests, and goal mutations.
- Enforce the same policy for goal mutations on unloaded threads while keeping
goal reads and turn interruption available.
- Document the affected endpoint behavior and continue exposing
`canAcceptDirectInput: false` for parent-owned subagents.
## Testing
- Cover direct-input rejection for both legacy and paginated thread history.
- Cover goal mutation ownership checks for unloaded V2 subagents, V1
subagents, and non-subagent V2 threads.
GitOrigin-RevId: 791b7af98490aed5eab4e672b90661acad11ec23
## What changed
- Add experimental `mcpServer/event/stream/start` and `mcpServer/event/stream/stop` requests for hosted apps, plus `mcpServer/event/stream/notification` forwarding.
- Scope subscriptions to the owning app-server connection and subscribed thread, enforce unique IDs and a per-connection limit, and clean them up when the thread is unsubscribed or the connection closes.
- Wait for the MCP active notification before completing startup, retry streams that close immediately, and terminate them when authentication or hosted runtime ownership changes.
## Testing
- Add an app-server integration test covering activation, event forwarding, duplicate subscription rejection, and explicit cancellation.
GitOrigin-RevId: 8a6fc1615adfc5af7e67def3b824fa5909ab3e7b
## Why
Environment-owned permission profiles and workspace roots must remain effective
without being persisted or restored as thread-owned settings.
## What changed
- Keep thread settings snapshots and restore data separate from the effective
configuration supplied by the primary environment.
- Use resolved environment permissions, active profiles, workspace roots, and
network policy when building turn context and session events.
- Preserve environment selections when agents are evicted, resumed, or spawned,
and validate owner configuration when it becomes ready.
- Start memory initialization only after the primary environment is configured.
## Testing
- Extend remote-environment and multi-agent tests to cover settings persistence,
owner permission profiles, workspace roots, spawning, eviction, and resume.
GitOrigin-RevId: d82f126981cd0190233020bbdd61d96c70558868
## What changed
- Add a shared helper for recovering the latest persisted approvals reviewer from turn context and thread settings history.
- Use the helper when resuming and forking threads while continuing to honor explicit request overrides.
- Fall back to an older persisted reviewer when the latest turn context omits the field.
## Testing
- Add unit coverage for settings snapshot precedence, turn context precedence, and fallback to an older reviewer.
GitOrigin-RevId: dfc0332b0f1410a4c9a550236eb32624f5133baa
## What changed
- Stop fetching the ChatGPT workspace `enable_plugins` setting.
- Let the effective Codex feature configuration control app and plugin APIs,
plugin-provided skills and hooks, and experimental feature reporting.
GitOrigin-RevId: 46aebf0f07cd47e093e48663e41207cdf9a38c9f
## What changed
- Discover synchronous `mcp_tool` hook handlers and invoke their configured MCP server and tool through a supplied executor.
- Expand nested hook-event placeholders in MCP tool inputs while preserving JSON types, and process tool output through the existing hook output contract.
- Represent hook details as handler-specific metadata in `hooks/list`, including MCP server and tool fields, and show those details in the TUI hooks browser.
- Skip unsupported `SessionEnd` MCP hooks and runtimes without MCP invocation support with startup warnings.
## Testing
- Cover argument expansion, missing placeholders, MCP invocation and hook decisions, discovery warnings, `hooks/list` metadata, and TUI rendering.
GitOrigin-RevId: 295b845471fe92bd7ad7cd272fbcd2c3713912e0
## What changed
- Add `EnvironmentConfigState` to `TurnEnvironmentSelection` so each environment attachment can inherit thread configuration or carry ready configuration for its login-shell policy and selected capability roots.
- Apply ready configuration during thread creation and thread-settings updates while reusing the existing environment connection.
- Validate selection configuration before applying settings, rejecting unsupported pending state and invalid capability roots.
## Testing
- Cover attachment-scoped capability roots, ready configuration at thread startup and turn updates, and rejection of invalid selections without changing existing settings.
GitOrigin-RevId: 86cf8f2148fdaa746ea0dd12890ab7b1577d7587
## What changed
- Add experimental `thread/queue/add`, `list`, `update`, `delete`, `reorder`, and `start` requests for persistent queued user submissions.
- Automatically dispatch queued submissions in FIFO order after completed or failed turns, while leaving the queue paused after interruption.
- Emit `thread/queue/changed` notifications and expose paginated queue contents with stable submission and client message IDs.
- Export the new protocol types through the generated JSON Schema and TypeScript bindings.
## Testing
- Add app-server integration coverage for capability gating, CRUD, pagination, capacity limits, notifications, automatic dispatch, cold-thread resume, interruption, and explicit queue starts.
GitOrigin-RevId: 89caf5577192199bda77cf6c372a59d26cdd910e
## Why
Project-local configuration can launch host processes. Requested write access may be reduced to read-only by managed constraints or platform support, so the request alone must not cause the app server to trust a project and load its configuration.
## What changed
- Base automatic project trust on the effective permission profile after configuration is loaded.
- Trust managed profiles only when their effective filesystem policy allows writes to the working directory.
- Continue resolving trusted nested working directories to the repository root.
## Testing
- Verify that managed read-only permissions neither persist project trust nor load a project-local MCP server when workspace-write access was requested.
- Cover effective read-only fallback for workspace-write requests and nested repository working directories.
GitOrigin-RevId: e548fd9c4552c328f779cc0365fe86f37d4a9b71
## What changed
- Extend `account/usage/read` with an optional `threadId` request and a
backward-compatible `threadUsage` response containing estimated credits,
optional USD cost, and model, reasoning, speed, and token breakdowns.
- Fetch thread usage for eligible Business and Enterprise plans when `/status`
is opened, then update the rendered status card asynchronously.
- Preserve terminal scrollback when replacing a visible status-card tail, and
append a refreshed card when the original tail can no longer be updated.
## Testing
- Add app-server coverage for authentication, canonical thread IDs,
unavailable billing routes, and malformed IDs.
- Add TUI coverage for usage formatting, stale responses, retries, history
updates, terminal reflow, and scrollback preservation.
GitOrigin-RevId: 49300914b3fba917c0f08e8595363e04e5ba6d37
## What changed
- Add `TurnInputRequest` and typed submission results for atomically starting a turn, steering the active turn, or declining input with a specific reason.
- Expose `start_or_steer_turn`, `start_turn_if_idle`, and `steer_turn` on `CodexThread`, and migrate Core consumers to these APIs.
- Make app-server `turn/start` steer an active regular turn and return that turn's ID. Reject incompatible output schemas and non-steerable turns without applying settings or enqueueing input.
## Testing
- Cover concurrent start-or-steer submissions, accepted and rejected settings updates, output-schema compatibility, idle-start rejection, and app-server steering.
GitOrigin-RevId: dd9b5528d76ec650c019e97af420bc13190ea86a
## What changed
- Add `--oauth-client-registration` with `auto` and `dcr` choices to `codex mcp add` and `codex mcp login`.
- Add the equivalent optional `clientRegistration` field to `mcpServer/oauth/login` and the generated protocol schemas.
- Keep automatic dynamic client registration as the default, prefer a configured OAuth client ID when present, and apply the selection only to the current login without persisting it in MCP configuration.
## Testing
- Cover dynamic registration and configured-client OAuth flows through the app server.
- Verify the CLI does not persist the per-login registration choice.
GitOrigin-RevId: 653a4a1054ff43c2c5d52ae863b6a96d21692a53
## What changed
- Add `codex-history` for model-history and persisted-rollout domain types, including `RolloutItem`, `RolloutLine`, `CompactedItem`, and initial/resumed history state.
- Re-export the persisted types from `codex-rollout` and update consumers to use the new crate boundary instead of `codex-protocol`.
- Preserve existing rollout serialization, including legacy numeric compacted-window IDs.
## Testing
- Add `codex-history` tests for rollout JSON round trips, compacted-history compatibility, persisted history modes, and multi-agent version selection.
GitOrigin-RevId: 944daa9297ddd231d3aebbdcb05fff4adf8b4e1b
## What changed
- Add the experimental `server/diagnostics` request, returning the app-server process ID, resident memory, platform-dependent physical footprint, and registered diagnostic gauges.
- Export the new protocol types in the generated JSON and TypeScript schemas and document the request.
## Testing
- Verify the response includes process measurements and the registered live-thread gauge.
- Verify the request is rejected unless `capabilities.experimentalApi` is enabled.
GitOrigin-RevId: 099d60a9c421a74ff1a72fe524e0dfeb89cf1057
## What changed
- Track Agent Plugin manifests through plugin, skill, and MCP loading so their capabilities use format-specific behavior without changing legacy plugins.
- Discover only direct-child skills, exclude app and hook capabilities, isolate MCP data, and reject MCP configuration files that are non-regular or resolve outside the plugin root.
- Bound model-visible skill instructions, plugin instructions, MCP descriptions, schemas, individual tools, and the aggregate Agent Plugin MCP tool set.
- Stop MCP and OAuth redirects when Agent Plugins send configured or authorization headers, while retaining existing redirect behavior for legacy MCP servers.
## Testing
- Add coverage for capability filtering, skill discovery, isolated MCP data and reserved-path expansion, unsafe MCP configuration files, context limits, and redirect handling.

## What changed
- Add `threadSection/create`, `threadSection/update`, and `threadSection/delete` app-server methods, with generated protocol schemas and TypeScript bindings.
- Persist custom sections in SQLite with stable UUIDv7 identities, trim and validate display names, and prevent renaming or deleting the built-in pinned section.
- Delete sections transactionally and return their active and archived threads to the unsectioned list.
- Serialize section mutations with section listing so concurrent requests observe ordered updates.
## Testing
- Cover section persistence across restarts, ordered renames, member cleanup on deletion, invalid requests, unsupported stores, and thread-store/state-runtime behavior.

## What changed
- Add `thread/section/move` to atomically move a thread into, within, or out of a section. Threads can be inserted before an existing member or appended, and moves within a section preserve `sectionEnteredAt`.
- Add `section_position` sorting to `thread/list`, with ascending order as its default, and expose `sectionEnteredAt` in thread responses.
- Persist section positions and entry times in SQLite, including migration of existing section members into recency order. Section membership is no longer updated through `thread/metadata/update`.
## Testing
- Cover section moves, reordering, pagination, persistence across restarts and rollout reconciliation, concurrent updates, and rank renumbering.

## What changed
- Enrich `thread/list` and `thread/search` results for loaded spawned threads with live status and `canAcceptDirectInput`.
- Report `true` for V1 agents that accept direct input and `false` for parent-owned V2 agents, while leaving the capability `null` when it is unavailable or inapplicable.
- Distinguish untracked threads from threads known to have shut down when resolving loaded status.
## Testing
- Cover list, search, ancestor-filtered list, and rejected V2 direct-input behavior.

## 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.

## 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.

## 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.
