## Why
Model-reachable child processes should not inherit Codex launch context.
## What changed
- Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching.
- Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes.
## Testing
- Cover inherited and explicitly configured variants, including mixed-case names.
- Verify the variables are absent from real child environments and app-server command and process execution.
GitOrigin-RevId: 2535527893985fef0995617f4c5b2462bea7c136
## What changed
- Add `executionMode` to `HookMetadata` returned by `hooks/list`, with `sync` as the default for compatibility.
- Propagate each discovered hook's `sync` or `async` mode through the app-server protocol and generated schemas.
- Show the execution mode in the TUI hooks browser.
## Testing
- Cover async and default-sync modes in `hooks/list` tests and TUI snapshots.
GitOrigin-RevId: 9c9f2890798fe417face76c15847616b2dea9db4
## What changed
- Filter saved `allow` prefix rules from the execution policy for cyber-specialized models and models listed in `auto_review.ignore_rules`, while preserving prompt, forbidden, network, and host-executable policy entries.
- Apply the filtered policy consistently to permission instructions, shell commands, unified exec, and the zsh-fork backend.
- Limit cyber-model command approvals to one-time decisions without proposing reusable policy amendments. General models continue to honor saved prefixes, including after switching models within a thread.
## Testing
- Add policy-level coverage for filtering allow-prefix rules while retaining restrictive and network rules.
- Add end-to-end coverage across shell and unified exec paths, zsh-fork execution, user and automatic review, and model switching.
GitOrigin-RevId: f3bd3872424291b12354ec415f33986ec369a368
## What changed
- Add the managed `auto_review.required_on_models` requirement, unioning model slugs across requirement layers and exposing the result through `configRequirements/read`.
- Force listed models to use `on-request` approvals with the `auto_review` reviewer. Downgrade Full Access to workspace-write when starting a protected session, and reject incompatible runtime overrides or use when automatic review is disabled.
- Preserve these protections across thread starts, resumes, forks, model changes, turn overrides, MCP approvals, and TUI session attachment.
## Testing
- Add coverage for layered model requirements and exact provider-alias matching.
- Add app-server tests for protected thread lifecycle operations, unsafe setting overrides, legacy thread upgrades, disabled automatic review, and requirements API output.
GitOrigin-RevId: c4b1d52c3b5b75e86880725412b8f0812e0dfcd9
## What changed
- Add lifecycle-backed gauges for in-flight and queued app requests, pending server requests and mailbox messages, active turns, and live MCP connections.
- Register each gauge on first use and decrement it when the tracked work or resource is dropped.
- Document the new `server/diagnostics` gauge names and account for the diagnostics request itself in the response example and test.
GitOrigin-RevId: 4bb82a3918af0b502d149b5d761ad669b2083f39
## 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
- Use `HostSkillRoot` throughout host root resolution and loading, including plugin roots.
- Remove the duplicate loader, root snapshot, and product-filtering implementation from `core-skills` now that loading is owned by the skills extension.
- Move and expand loader coverage for discovery, namespaces, filesystem routing, root merging, symlinks, and frontmatter parsing.
## Testing
- Added focused unit and integration tests under `ext/skills` and `skills` for the consolidated loader behavior.
GitOrigin-RevId: 214d06d59bf3033ee0f220ea5959ee4feff66782
## Why
Persisted base instructions need to retain whether they were explicitly customized or generated from a model template. Without that distinction, forks and config-lock replays can treat model-generated instructions as custom and keep the wrong template after a model or personality change.
## What changed
- Record custom or model provenance with base instructions in rollouts and config locks.
- Preserve custom instructions across model changes, while allowing model-generated instructions to follow the selected model and personality.
- Keep legacy rollouts without provenance compatible and propagate provenance through forks and spawned agents.
## Testing
- Cover provenance serialization and legacy rollout decoding.
- Cover role personality changes, forked model changes, config-lock replay, and multi-agent configuration.
GitOrigin-RevId: 801c26559835f558027ce5112700c0cd31fcb21b
## What changed
- Add nullable `multiAgentVersion` metadata to v2 `model/list` responses.
- Represent supported values as `disabled`, `v1`, or `v2` in the Rust API and generated JSON Schema and TypeScript exports.
- Forward the value from model catalog presets through app-server responses.
## Testing
- Extend the remote model catalog test fixture with a `v2` multi-agent version.
GitOrigin-RevId: bd3b2bbe0a3b562b4d1f03df7da2a73a35713978
## What changed
- On cold `thread/resume`, restore the latest approval policy from persisted
thread settings instead of falling back to the current configured default.
- Preserve the precedence of an explicit request override over the persisted
policy.
- Account for settings applied during a turn when the subsequent compacted turn
context contains a stale policy.
## Testing
- Add unit coverage for selecting the latest persisted policy.
- Add app-server tests for legacy and paginated history, including explicit
resume overrides.
GitOrigin-RevId: 9127a3c53a90f16d67957ded9e7430e79180fc60
## What changed
- Parse `mcp_tool` hook handlers with a server, tool, JSON input, and optional timeout and status message.
- Return managed MCP tool hooks from `configRequirements/read` and include the handler in the generated protocol schemas.
- Skip MCP tool hooks during discovery with an explicit warning until execution is supported.
## Testing
- Cover MCP tool hook deserialization, including nested and null JSON input values.
- Extend the config requirements RPC test to verify the new handler shape.
GitOrigin-RevId: ff7e2d12b75b486c54d63469af547a29f9b31418
## Why
An account change can select different OpenTelemetry collector settings. The
long-running app server needs to stop exporting telemetry with the previous
account's configuration.
## What changed
- Rebuild and install the log, trace, and metrics exporters when authentication
changes, and shut down the previous provider without blocking the app server.
- Make cached global metrics clients and the tracing layer follow the replacement
provider so existing callers continue exporting through the current account's
configuration.
- Clear the cached cloud configuration loader after login and logout so telemetry
reloads from the new account context.
## Testing
- Add an app-server integration test that switches accounts and verifies logs,
traces, and metrics reach the new collector while trace context is preserved.
- Add a metrics test covering cached clients after provider replacement.
GitOrigin-RevId: a74359777a35edbee5bbe0b2baccc155074cb172
## Why
Subagents can reuse cached MCP tool definitions without starting every optional
server before any of its tools are used.
## What changed
- Defer startup for subagent-owned, optional MCP servers when their cache has at
least one visible, allowed tool, and trigger startup on the first operation
that needs the live client.
- Keep root sessions, required servers, selected plugin servers, and explicit
reconnects eager.
- Exclude empty catalogs from cache eligibility and keep dormant servers out of
the initial startup summary.
## Testing
- Extend MCP tool-cache coverage for eager root startup, unused and filtered
subagent servers, deferred startup status events, and startup that survives an
interrupted first tool call.
GitOrigin-RevId: e7528ff08312583a6747cbc6550ea5b6eabda9a6
## What changed
- Add a storage-neutral queue extension for listing, adding, editing, reordering, deleting, and explicitly starting queued user messages.
- Dispatch queued messages in FIFO order when a thread becomes idle after a completed turn, while leaving them queued after interruptions or failures.
- Wait for user input to be persisted before removing its queue item, and report hook rejection, task termination, and persistence failures distinctly.
- Snapshot local image and audio attachments into validated data URLs before storing them, enforce input limits, and emit `ThreadQueueChanged` events after mutations.
## Testing
- Cover queue mutations, automatic and explicit dispatch, interruption and failure behavior, hook rejection, invalid records, input limits, and local attachment snapshotting.
GitOrigin-RevId: 14f39d7c8cbaccb767a6da84b82cced0edfcb4b9
## What changed
- Emit `codex_thread_archive_event` when a thread is successfully archived or
unarchived, including the thread ID, action, and producer timestamp.
- Route archive notifications through the analytics client while preserving
normal app-server notification delivery.
## Testing
- Extend app-server coverage for archive and unarchive analytics, including
descendant archives and a repeated archive request that fails without
producing another event.
GitOrigin-RevId: 0d973c232fd795b7cd6cddd47ecc9446234c44dd
## What changed
- Add `transparentBackground` to image-generation items and legacy completion events.
- Map Images API backgrounds to `true` for transparent, `false` for opaque, and `null` for automatic or unavailable values.
- Preserve the metadata in live notifications and persisted or resumed thread history while continuing to deserialize older items that omit it.
## Testing
- Cover transparent, opaque, and automatic backgrounds, including image edits and thread read/resume flows.
- Verify the stable JSON shape and optional TypeScript field.
GitOrigin-RevId: 08527f37f23431df45fab1ed34eb82b2139b49d7
## Why
Authentication restrictions must apply before stored or environment-provided credentials can be used, including during bootstrap before cloud requirements are fetched.
## What changed
- Add local `requirements.toml` allowlists for login methods and ChatGPT workspaces. Ignore these fields in cloud-provided requirements.
- Combine managed workspace allowlists with existing workspace restrictions by intersection, and fail closed when the resulting policy permits no usable login method.
- Centralize policy checks in the authentication manager so CLI, TUI, app-server, external-auth, and credential-loading paths consistently reject disallowed authentication before token hydration or network requests.
## Testing
- Cover policy composition, workspace intersection, invalid stored and external credentials, bootstrap enforcement, and login endpoint restrictions.
GitOrigin-RevId: efef22b248f3c3333e9aa55423e539efa2d2dd48
## What changed
- Propagate the optional `modelSpecialty` field through the model catalog and
app-server `model/list` response.
- When a newly selected model has the `cyber` specialty, default an active TUI
thread to workspace-write permissions with on-request approval. Use auto
review when available, otherwise keep the user as reviewer, while respecting
configured permission requirements.
- Show a notice when auto review is applied and strengthen the full-access
warning for cyber models.
- Preserve explicitly selected permissions when only reasoning settings change.
## Testing
- Cover auto-review defaults, requirement-aware fallback behavior, permission
preservation across reasoning changes, and the new warning notice.
GitOrigin-RevId: 8f25b0082d3051d9ff91f7355921236d0f82f758
## 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.
GitOrigin-RevId: c9af66b051269f3226628ca280a58d32c808c38f
## What changed
- Key cached skill snapshots by filesystem and plugin snapshot identity so compatible config and working-directory loads can share results without reusing stale plugin data.
- Coalesce concurrent loads for the same cache key and replace the cached entry on forced reload.
- Clear both plugin and skill caches when `skills/list` forces a reload, and bypass working-directory caching when effective plugin roots are present.
## Testing
- Cover concurrent cache sharing, filesystem isolation, forced reloads, and refreshed plugin skill metadata in host service and app server tests.
GitOrigin-RevId: 03fed3b40d45bb29206d5a3c3e78f06df04dbb1e
## Why
Clients using `thread/read` with `includeTurns: true` need the legacy full-history
view even when a thread stores its history in paginated form.
## What changed
- Reconstruct full projected turns from paginated history for both stored and
loaded threads.
- Keep `thread/turns/list` and `thread/items/list` as the preferred incremental
history APIs.
## Testing
- Cover `thread/read(includeTurns=true)` before and after a paginated thread is
loaded.
GitOrigin-RevId: 6efdc04e5ed3cad2ff2078d8103933082c7921db
## What changed
- Add a hidden global `--psp` runtime flag and propagate it through TUI, exec,
app-server, remote-control, and in-process startup paths.
- Attach the `oai-chat-psp=true` cookie to first-party ChatGPT requests when
enabled, using a cached cookie-aware client with sensitive request logging
disabled.
- Keep the routing selection out of persistent configuration layers while
preserving it across config refreshes and agent role changes.
## Testing
- Cover global flag parsing, app-server propagation, config-layer isolation,
and preservation across config rebuilds and role changes.
GitOrigin-RevId: 05cdc61ffd7162d8e48fc1e166f4732113e5a816
## Why
Session IDs are derived from file stems and can repeat across projects. Keying
connector attribution only by session ID can therefore assign one session's
connectors to another session during a batched migration.
## What changed
- Preserve connector candidates by canonical source path until each imported
session is annotated, then aggregate them for detection summaries.
- Resolve project-backed MCP tool calls from both `CallMcpTool` server IDs and
`mcpDetails.serverName`, while requiring a match in project metadata.
## Testing
Add coverage for duplicate session stems, per-source connector results, and
both supported project-backed MCP tool-call formats.
GitOrigin-RevId: 10563d47c29673c07daa83be5f4e1a256740b901
## Why
Cursor stores projectless chats under the reserved `empty-window` project, and
their transcripts may not contain embedded working-directory metadata.
## What changed
- Resolve `empty-window` sessions to the parent of the Cursor home directory,
including when that home is configured as a relative path.
- Record each created or appended session's working directory in its import
success result instead of inheriting the migration item's directory.
## Testing
- Cover projectless Cursor transcripts without embedded metadata.
- Cover working-directory resolution from a relative Cursor home.
GitOrigin-RevId: 21cc7ea6acab1ed80cc4016a881e07eca3d0abbd
## What changed
- Return connector candidates found in detected external agent sessions, aggregating session counts by connector name.
- Resolve connector names from both cached plugin manifests and project MCP server metadata.
- Persist detected connector clues in the session import ledger and merge them into completed imports without case-insensitive duplicates.
## Testing
- Add coverage for project MCP metadata detection and for accumulating detected and imported connector candidates.
GitOrigin-RevId: 97a7dfe4a61599686b2222cddd9595acec8b4501
## Why
Paginated threads should not require the TUI to load and render their entire
history when a session is resumed.
## What changed
- Hydrate a bounded initial history page for paginated resumes and forks,
respecting the configured terminal reflow row budget.
- Load older transcript items in the background as users navigate upward, while
preserving the viewport, live output, and backtrack selection.
- Reconcile review-mode prompts across page boundaries and keep restored token
usage hidden until it can be attributed to a persisted turn.
## Testing
- Added coverage for paginated resume and fork hydration, older-page merging,
transcript prepending, backtrack behavior, review prompt filtering, and token
usage restoration.
GitOrigin-RevId: 42160b943a9f6a1ba0cfe4b195c24ddf410b747d
## What changed
- Move host skill discovery, snapshot caching, and configuration handling from
`codex-core-skills` to `codex-skills-extension`.
- Rename `SkillsService` and `SkillsLoadInput` to `HostSkillsService` and
`HostSkillsLoadInput` to distinguish the host implementation from other skill
providers.
- Keep shared loading primitives and skill outcome modeling in
`codex-core-skills`.
GitOrigin-RevId: d81a21791d2ef8c066e157e7e538b8cb7ee4c24b
## What changed
- Discover plugins from configured and repository marketplaces using the request's `cwds`, and merge up to 100 ranked local matches into the first remote result page.
- Match local plugin names, display names, and keywords without case or punctuation sensitivity, while applying global, personal, and workspace scope semantics.
- Deduplicate local and remote copies, preserve local installation metadata on the remote result, and treat the remote global catalog as authoritative over the local curated marketplace.
- Keep local search available for API-key authentication and when `remote_plugin` is disabled, and consistently report `enabled: false` because search results describe discovery rather than effective activation.
## Testing
- Add coverage for merged pagination and ranking, API-key local search, scope and feature behavior, deduplication, installed state, and explicit disabled-state reporting.
GitOrigin-RevId: 63696a00d16166dfdd86e0cc456769c583ebe9a7
## What changed
- Add `AppToolPolicyEvaluator::apply_app_enabled_state` and use it when
presenting app lists, building plugin context, and deciding whether app
instructions are available.
- Preserve each app's source state unless local or managed configuration
explicitly overrides it.
- Keep connector discovery and post-install refresh checks based on raw
accessibility rather than configured enablement.
## Testing
- Cover default enablement, per-app overrides, managed disablement, and
preservation of unconfigured source state.
GitOrigin-RevId: f1a62d55e7cc48b37113848e3baa0d69d8d9c8a8
## Why
App-server clients need to advertise structured MCP extension settings, including supported MCP App UI MIME types, rather than only opting into OpenAI form elicitation with a boolean.
## What changed
- Add an `extensions` map to initialize capabilities and preserve `mcpServerOpenaiFormElicitation` as a legacy alias for `openai/form`.
- Capture the declared extension profile when a thread is started, resumed, or forked, propagate it to subagents, and advertise it to downstream MCP servers during initialization.
- Keep the profile stable for the lifetime of the loaded session instead of changing it on later turns or direct tool calls.
## Testing
- Cover extension conversion, downstream MCP initialization, session isolation, legacy form support, and subagent inheritance.
GitOrigin-RevId: fbcedbb74ce788e574b0f884a4c45c4cedb9de54
## Why
Client-facing command execution items can include recognizable secrets in the
rendered command or parsed command actions.
## What changed
- Redact secrets in `commandExecution.command` and `commandActions` for live
items, completed items, and replayed thread history.
- Keep command approval requests backed by the original executable command and
parsed actions while using the redacted representation for display items.
- Document that execution item commands are redacted display values rather than
executable commands.
## Testing
- Cover redaction for command conversion, parsed search actions, legacy replay,
approval flows, completion notifications, and rejected commands.
GitOrigin-RevId: 2ad056f21882bf5166182ad1a4ff0bf6471d9c0e
## What changed
- Replace the ordering enum and `include_disabled` boolean with named
`ConfigLayerStack` iterators for each precedence direction.
- Keep enabled-only iteration separate from `all_layers_*` iteration, which
includes disabled layers.
- Update config consumers to use the iterator matching their precedence and
disabled-layer requirements without allocating an intermediate `Vec`.
## Testing
- Add coverage that verifies ordering and disabled-layer filtering for all four
iterators.
GitOrigin-RevId: d14df3db4a2eae80ba97cdec246bff405e6c5f3d
## What changed
- Parse `codex_rollout_budget_units` from completed Responses API usage into
`TokenUsage`.
- Keep the provider-only value out of serialized protocol, JSON schema, and
TypeScript representations.
## Testing
- Cover the value in unit and end-to-end SSE response parsing tests.
GitOrigin-RevId: a53d4202beb9c8985d25894cb10e7c01f20b2a44
## What changed
- Accept the allowlisted `.onboarding_entrypoint=life_sciences` suffix on a valid OAuth state while continuing to reject unknown or malformed suffixes.
- Return the parsed callback metadata from the login server without including the suffix in the token exchange redirect URI.
- Add the optional `onboardingEntrypoint` field and `life_sciences` value to the v2 `account/login/completed` notification and generated protocol exports.
## Testing
- Cover valid, invalid, and repeated OAuth state suffixes.
- Verify the end-to-end login callback result, token redirect URI, and app-server notification payload.
GitOrigin-RevId: c2ee146328ddd43c03a503260d5d492e186fa889
## Why
Setting or clearing a thread goal could reconcile an already indexed rollout and overwrite SQLite-only thread metadata, including the thread preview.
## What changed
Skip rollout reconciliation when SQLite already references the same existing rollout and its session metadata matches the requested thread. Continue reconciling when the SQLite row is missing or the stored rollout is invalid so goal mutations can still repair thread metadata.
## Testing
Add coverage that verifies goal set and clear preserve SQLite previews, and that goal set restores a deleted SQLite thread row.
GitOrigin-RevId: cf19cef98559fc67182ac7430e4e50ed2eed83f3
## What changed
- Add the optional `delegationAckFiller` field to `thread/realtime/start`.
- Forward explicit `true` or `false` values to V3 Frameless Bidi session payloads as `delegation.ack_filler`; leave the field absent when unspecified so the Realtime API default is preserved.
- Document that V1 and V2 ignore this setting.
## Testing
- Cover both boolean values in Frameless Bidi serialization and verify the WebRTC V3 session creation payload.
GitOrigin-RevId: 9fe8efd14e42738c3e86e3e9a8af81d0f4521244
## Why
Clients need to know whether a `request_user_input` request must wait for an
explicit response or may auto-resolve. Using `autoResolutionMs` as that signal
conflated the blocking decision with timeout policy.
## What changed
- Add required `isBlocking` fields to user input protocol and app-server
request payloads. Plan-mode requests are blocking, while requests from other
enabled modes are non-blocking.
- Drive the TUI's auto-resolution behavior from `isBlocking` and remove
`autoResolutionMs` from the model-facing tool schema.
- Deprecate `autoResolutionMs` while retaining it for compatibility, and treat
legacy payloads without `isBlocking` as blocking.
## Testing
- Cover mode-derived blocking behavior, legacy deserialization, app-server
forwarding, delegated requests, and TUI auto-resolution.
GitOrigin-RevId: 29aade657ef743065ec264376ba567a9b353d7d7
## What changed
- Implement `plugin/search` by querying the remote plugin service without using the catalog cache.
- Support global, workspace, and personal scopes with bounded page sizes and passthrough cursors.
- Respect plugin feature gates and omit shared workspace results when plugin sharing is disabled.
- Keep search terms and pagination tokens out of transport errors and telemetry, and return search results as uninstalled plugin summaries.
## Testing
- Add remote search coverage for request parameters, result conversion, authentication, pagination, scope mapping, and error redaction.
- Add app-server coverage for remote-plugin and plugin-sharing feature gates.
GitOrigin-RevId: ac29c5480ed8089d998b6275bc5f11c8d9a43fd1
## What changed
- Add optional `realtimeStartInstructions` and `realtimeEndInstructions` fields to `thread/realtime/start`.
- Apply the instructions when Codex enters and leaves realtime mode, while preserving the existing defaults when either field is omitted.
- Limit each field to 8,192 estimated tokens.
## Testing
- Cover custom entry and exit instructions across realtime state transitions.
- Cover token-limit validation for both fields.
GitOrigin-RevId: b9cfa1ff22e084d8a6b2ed56bd27d95ffdd6b6bd
## What changed
- Add the experimental `plugin/search` request with search term, scope, working-directory, cursor, and limit parameters.
- Define paginated results that include each plugin's marketplace name and optional local marketplace path.
- Route the request through app server while returning method-not-found until the search implementation is available.
## Testing
- Add an app-server test that verifies `plugin/search` returns JSON-RPC error `-32601` with the expected not-implemented message.
GitOrigin-RevId: 755400468331f0887f7da7d933195c347aadf6d0
## 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.
GitOrigin-RevId: dc9a4be283c21dbc93ab1829eafc4825d8df6575
## Why
External agent session files can gain messages after their initial import. Re-importing those files should extend the existing Codex thread instead of creating a duplicate.
## What changed
- Map a changed source session back to its uniquely imported thread and append only the missing transcript suffix.
- Update the import ledger after verifying that the source and destination transcripts match.
- Defer the update when the target is active, archived, ambiguous, diverged, or otherwise unsafe to modify.
## Testing
Added unit and app-server coverage for suffix planning, ledger checkpointing, concurrent updates, and unsafe targets that must be deferred.
GitOrigin-RevId: 3d9e71cd66e8b31cf5128e8869063868bfb3eb05
## Why
MCP servers running in an executor must not reuse host-owned OAuth credentials,
even when they have the same configured server name and URL.
## What changed
- Derive environment-scoped credential names for executor-owned MCP servers and
use them consistently for login, logout, authentication, and connection setup.
- Mark executor-owned entries in the file credential store and fail closed when
loading or saving an entry could cross the host/executor boundary.
- Preserve compatibility with existing local OAuth credentials, including local
server names that overlap the new reserved prefixes.
## Testing
- Extend the executor MCP integration test to verify that executor requests use
the executor token, never send the host token, and persist both credentials
separately.
GitOrigin-RevId: 4fc92d0533b0fe2e0df34f6d47b81e3d20d07807
## Why
Report prompt metadata should reflect the persisted rollout instead of
unverified tags supplied by the client.
## What changed
- Hash the session's base instructions with SHA-256 after normalizing
whitespace, and add the result to report uploads as `prompt_hash`.
- Treat `prompt_hash` and `prompt_version` as reserved tags: remove
client-provided values and only restore `prompt_hash` when it can be derived
from the rollout.
- Collect the prompt hash alongside the selected turn's model and reasoning
effort metadata.
## Testing
Added unit tests for prompt normalization, rollout metadata selection, and
replacement or removal of client-provided prompt tags.
GitOrigin-RevId: 4a21d7b90e100f96f3f7b39d07fec75b30c0d33f
## What changed
- Add a `connectors` array to `ExternalAgentConfigDetectResponse` with each candidate's normalized name, detected session count, and detection source.
- Define detection sources for remote MCP server configuration and session tool use, and export the corresponding JSON Schema and TypeScript types.
- Default `connectors` to an empty array when deserializing responses from older servers.
## Testing
- Add a protocol test covering deserialization when `connectors` is omitted.
GitOrigin-RevId: b65d76791099385226ed54411f4c1ef902be43d8
## What changed
- Send the active turn ID in the `x-codex-image-turn-id` header for image generation and edit requests.
- Add `explicit_client_interrupt_requested_at_ms` to turn analytics. Record the earliest explicit interrupt request that receives a successful response, while excluding rejected requests.
- Track errors returned by `turn/interrupt` so pending analytics state is cleaned up correctly.
## Testing

## What changed
- Propagate MCP tool `readOnlyHint` annotations through tool-call start and
completion events.
- Include the optional hint in persisted thread history and app-server
`mcpToolCall` items, preserving compatibility when the annotation is absent.
- Document that the hint describes tool capability, not the outcome of a
particular invocation.
## Testing
- Cover read-only and write-capable tools in live events and persisted rollout
data.
- Verify the hint survives thread reads and resumes for both in-progress and
completed MCP calls.

## Why
Closing stdin could leave the app-server running when a remote-control client
was still connected.
## What changed
Track each connection's origin and shut down a stdio app-server when its stdio
connection closes, regardless of whether other connections remain. Report the
shutdown reason as `stdio_connection_closed`.
## Testing
Added a regression test that closes stdio while a remote-control connection is
active and verifies that the app-server exits and disconnects the remote client.
