• Preserve namespaces on custom tool calls (#30302)

  ## Summary
  
  - Preserve the optional namespace on custom tool calls during response
  deserialization and app-server replay.
  - Use the namespaced tool identifier for streaming argument handling and
  tool dispatch.
  - Regenerate app-server protocol schemas.
  - Add regression tests covering namespace serialization and routing.
  
  ## Testing
  
  - Ran affected protocol and app-server test suites.
  - Ran the full core test suite; two load-sensitive timing tests passed
  when rerun individually.
  - Ran Clippy and formatting checks.
  - Verified with a local end-to-end app-server replay that the namespace
  is preserved through the complete request/response flow.

• [codex] Support npm marketplace plugin sources (#29375)

  ## Why
  
  Marketplace source deserialization treated `{"source":"npm", ...}` as
  unsupported. The loader logged and skipped the entry, so npm-backed
  plugins never appeared in `plugin list --available` and `plugin add`
  returned "plugin not found".
  
  Codex plugins are installed from a plugin root, not from an npm
  dependency tree. For npm-backed marketplace entries, Codex should fetch
  the published package contents without running package scripts or
  installing unrelated dependencies.
  
  ## What changed
  
  - Add `npm` marketplace plugin sources with `package`, optional semver
  `version` or version range, and optional HTTPS `registry`.
  - Reject unsafe npm source fields before materialization, including
  invalid package names, non-semver version selectors, plaintext or
  credential-bearing registry URLs, and registry query/fragment data.
  - Materialize npm plugins with `npm pack --ignore-scripts`, then unpack
  the resulting tarball through the existing hardened plugin bundle
  extractor.
  - Enforce npm archive and extracted-size limits, require the standard
  npm `package/` archive root, and verify the extracted `package.json`
  name matches the requested package before installing.
  - Keep plugin listings, install-source descriptions, CLI JSON/human
  output, app-server v2 `PluginSource`, TUI source summaries, regenerated
  schema fixtures, and app-server documentation in sync.
  
  ## Impact
  
  Marketplaces can distribute Codex plugins from public or configured
  private HTTPS npm registries using the same install flow as existing
  materialized plugin sources. `npm` must be available on `PATH` when an
  npm-backed plugin is installed.
  
  Fixes #27831
  
  ## Validation
  
  - `just write-app-server-schema`
  - `just test -p codex-core-plugins -p codex-app-server-protocol -p
  codex-app-server -p codex-cli`
    - npm/schema/core-plugin coverage passed in the run.
  - The full focused command finished with `1739 passed`, `11 failed`, and
  `6 timed out`; the failures were unrelated local app-server environment
  failures from `sandbox-exec: sandbox_apply: Operation not permitted`
  plus one missing `test_stdio_server` helper binary.
  - Installed an npm-published Codex plugin package through a throwaway
  local marketplace and throwaway `CODEX_HOME` to exercise the real npm
  materialization path end to end.

• feat(app-server): add optional turn_id to thread/fork (#30277)

  ## Description
  
  This adds stable optional `turnId` support to `thread/fork`. When
  supplied, the fork copies persisted history through that terminal turn,
  inclusive, and drops later turns from the new thread.
  
  Omitting or passing `null` preserves the existing full-history fork
  behavior, including the interruption marker when the stored source
  history ends mid-turn.
  
  ## Why
  
  We're deprecating `thread/rollback` and this will help certain UX use
  cases work around it by using `thread/fork` + `turn_id` instead.

• [codex] Add managed new-thread model settings (#29683)

  ## Why
  
  Admins need persistent defaults for the model, reasoning effort, and
  service tier shown when the Desktop App creates a new thread. These are
  initialization defaults rather than runtime constraints: the App should
  use them to initialize its draft while still allowing a user to make an
  explicit selection.
  
  The app-server therefore needs to expose the managed values before
  thread creation without changing `thread/start` behavior for other
  clients.
  
  ## What changed
  
  - Parse `model`, `model_reasoning_effort`, and `service_tier` from
  `[models.new_thread]` in `requirements.toml`.
  - Compose the `models` requirements through the existing
  requirements-layer precedence rules.
  - Expose the resolved values through `configRequirements/read` as
  `requirements.models.newThread`.
  - Add the corresponding app-server protocol types and regenerate the
  JSON and TypeScript schema fixtures.
  - Document the new `configRequirements/read` fields in the app-server
  README.
  
  ## Scope
  
  This PR is data plumbing only. It does not apply these values during
  `thread/start` and does not change thread creation for existing
  app-server clients, resumed or forked sessions, internal or subagent
  sessions, `codex exec`, or the TUI. A companion Desktop App change owns
  draft initialization, sends the effective settings for ordinary and
  prewarmed starts, and preserves explicit user changes.
  
  ## Validation
  
  - Requirements deserialization coverage for `[models.new_thread]`
  - Requirements-layer precedence coverage
  - App-server API mapping coverage
  - `configRequirements/read` integration coverage
  - Regenerated app-server JSON and TypeScript schema fixtures

• feat(app-server): add history_mode to thread (#29927)

  ## Description
  
  This PR adds a new `historyMode = "legacy" | "paginated"` to `Thread`.
  This will be stored in `SessionMeta` in the JSONL rollout file and as a
  new column in the SQLite thread_metadata table, and exposed on
  `thread/start` and on the `Thread` object in app-server.
  
  ## What changed
  
  - Added canonical `ThreadHistoryMode` with `legacy` and `paginated`,
  defaulting old and new SessionMeta to `legacy`.
  - Carried `history_mode` through core session config, ThreadStore stored
  metadata, local/in-memory stores, rollout metadata extraction, and the
  existing SQLite `threads` table.
  - Added experimental `historyMode` to app-server v2 `Thread` and
  `thread/start`.
  - Made paginated stored threads metadata-discoverable but unsupported
  for legacy full-history reads, `load_history`, live resume, and create
  paths.
  - Regenerated app-server schema fixtures and added
  protocol/state/thread-store/app-server coverage for persistence and
  fail-closed behavior.
  
  ## Compatibility floor
  Because users may be running various versions of Codex binaries on the
  same machine (TUI, Codex App, etc.), we will need to establish a
  compatibility floor for upcoming paginated threads, which will change
  how thread storage reads and writes work.
  
  The overall plan here:
  ```
  Release N:
  - Add historyMode to SessionMeta / Thread / SQLite metadata.
  - Teach binaries to understand paginated threads.
  - If a binary sees `historyMode="paginated"` but does not support the paginated contract, it refuses to resume/mutate the thread.
  - Default remains `"legacy"`.
  
  Release N+1:
  - First-party clients start opting into paginated threads where appropriate.
  - Internal dogfood / staged rollout.
  - Measure old-client usage and paginated-thread unsupported errors.
  
  Release N+2:
  - Only after Release N+ is overwhelmingly deployed, make paginated the default.
  - Accept that a small tail of N-1-or-older binaries may not understand paginated threads.
  ```
  
  The important behavior change is fail-closed handling for a binary that
  encounters a persisted `paginated` thread before it knows how to fully
  support paginated history. In app-server, if a thread is `paginated`, we
  will:
  
  - allow metadata-only discovery paths like `thread/list` and
  `thread/read(includeTurns=false)`, so clients can still see the thread
  and inspect its `historyMode`
  - reject legacy full-history/live-thread paths like
  `thread/read(includeTurns=true)` and `thread/resume` with an unsupported
  JSON-RPC error
  - avoid silently treating an unknown or future `historyMode` as `legacy`
  
  Under the hood, the ThreadStore layer also rejects legacy operations
  that would need to load or replay the full thread history for a
  paginated thread. That gives us the behavior we want for Release N:
  future paginated threads are visible, but this binary fails closed
  instead of trying to operate on them as if they were legacy threads.

• Expose MCP app identity in app context (#29934)

  ## Why
  
  MCP tool-call events need to expose trusted app identity and action
  metadata directly so v2 clients do not have to infer it from tool names
  or resource URIs.
  
  ## What changed
  
  - Add optional `appName`, `templateId`, and `actionName` fields to MCP
  tool-call `appContext`.
  - Populate `appName` and `templateId` from trusted Codex Apps metadata,
  and derive `actionName` from the trusted app resource metadata.
  - Preserve all three fields through core events, legacy protocol events,
  persisted thread history, resume redaction, and app-server v2 responses.
  - Document the public `appContext` fields in
  `codex-rs/app-server/README.md`.
  - Regenerate app-server JSON and TypeScript schemas and add coverage for
  serialization, persistence, redaction, and metadata propagation.
  
  ## Validation
  
  - `just test -p codex-app-server-protocol mcp_tool_call`
  - `just test -p codex-core

• [codex] Surface MCP reauthentication-required startup failures (#29877)

  ## Summary
  
  - distinguish expired, non-refreshable stored MCP OAuth credentials from
  first-time missing credentials
  - carry a typed `failureReason: "reauthenticationRequired"` on the
  existing `mcpServer/startupStatus/updated` notification only when user
  action is required
  - keep the public MCP auth-status API unchanged and regenerate the
  app-server protocol schemas and documentation
  
  ## Why
  
  An MCP server with an expired access token and no usable refresh token
  currently fails startup without giving clients a reliable, typed
  recovery signal.
  
  The existing startup-status notification is the natural place to carry
  this state. Its nullable `failureReason` keeps the recovery reason
  attached to the failed startup transition without adding a one-off
  notification. Internally, Codex distinguishes first-time login from
  reauthentication and emits the reason only when the startup error itself
  requires authentication.
  
  ## User impact
  
  App clients can prompt an existing user to reconnect an MCP server when
  automatic recovery is impossible by handling a failed
  `mcpServer/startupStatus/updated` notification whose `failureReason` is
  `reauthenticationRequired`. Starting, ready, cancelled, unrelated
  failures, and first-time setup carry no reauthentication reason.

• Support OAuth for HTTP MCP servers from selected executor plugins (#28529)

  ## Why
  
  #28522 routes selected-plugin HTTP MCP traffic through the owning
  executor, but OAuth bootstrap and refresh still used host-local clients.
  Executor-only servers therefore cannot complete discovery or login
  through the same network boundary as the MCP connection.
  
  ## What changed
  
  - adapt `codex_exec_server::HttpClient` to RMCP 1.8's `OAuthHttpClient`
  contract
  - let RMCP own discovery, dynamic registration, PKCE, token exchange,
  and refresh
  - route auth status, persisted-token startup, and app-server login
  through the server runtime while preserving the existing local discovery
  path
  - add optional `threadId` to `mcpServer/oauth/login` and echo it in the
  completion notification
  - implement RMCP's redirect policy and 1 MiB OAuth response limit over
  executor HTTP
  - cover selected-thread OAuth discovery and login through an
  executor-only route
  
  Depends on #28522.

• [codex] rename rollout budget error to session budget error (#29744)

  ## Summary
  
  - rename the rollout-budget exhaustion error from
  `RolloutBudgetExceeded` to `SessionBudgetExceeded`
  - expose the matching app-server v2 wire value as

• protocol: separate app and exec RPC ownership (#29714)

  ## Why
  
  The app-server and exec-server expose separate JSON-RPC APIs, but
  exec-server currently sources its serialized protocol and envelope types
  through app-server-oriented code. Giving each API an explicit owner
  makes the crate boundary legible without introducing shared generic
  envelopes.
  
  ## What changed
  
  - Added `codex-exec-server-protocol` to own exec DTOs, process IDs, and
  JSON-RPC envelopes.
  - Updated exec-server clients, transports, handlers, and tests to use
  the new crate.
  - Exposed app-server's existing JSON-RPC types through a public `rpc`
  module while retaining root re-exports.
  - Preserved existing wire shapes, including exec `PathUri` behavior.
  
  ## Stack
  
  This is PR 1 of 6. Next: [PR
  #29721](https://github.com/openai/codex/pull/29721), which moves auth
  mode below the app wire boundary.
  
  ## Validation
  
  - Exec-server protocol and server coverage passed in the focused
  protocol test runs.
  - App-server protocol schema fixtures passed.

• [codex] surface rollout budget exhaustion (#29715)

  ## Summary
  - surface shared rollout-budget exhaustion as
  `CodexErr::RolloutBudgetExceeded` instead of a generic interrupted turn
  - map it through the existing `CodexErrorInfo` and app-server v2
  `codexErrorInfo` path
  - keep local compaction from retrying after the shared rollout budget is
  exhausted
  
  This gives app-server clients a stable `rolloutBudgetExceeded` error
  they can classify without guessing from `status="interrupted"`.
  
  ## Tests
  - `just test -p codex-core rollout_budget`

• Make selected plugin roots URI-native (#28918)

  ## Why
  
  Selected capability roots belong to the executor filesystem, not the
  app-server host. Converting their path strings into the host's native
  `Path` breaks whenever the two machines use different path conventions,
  such as a Windows executor behind a Unix app-server.
  
  This PR establishes `PathUri` as the selected-plugin boundary so the
  executor remains authoritative for its paths.
  
  ## What changed
  
  - Require `selectedCapabilityRoots[].location.path` to be a canonical
  `file:` URI and deserialize it directly as `PathUri`; native path
  strings are rejected.
  - Update the app-server schema, generated TypeScript, examples, and
  request coverage for the URI contract.
  - Keep selected roots, resolved plugin locations, manifest paths, and
  manifest resources as `PathUri`.
  - Inspect and read plugin roots and manifests only through the selected
  environment's `ExecutorFileSystem`.
  - Parse executor manifests with the shared URI-native parser from #29620
  instead of projecting them onto the host filesystem.
  - Enforce resource containment lexically and preserve the root URI's
  POSIX or Windows path convention.
  - Cover foreign Windows plugin roots and URI-native manifest resources.
  
  ```text
  thread/start
    selectedCapabilityRoots[].location.path = "file:///C:/plugins/demo"
                                | PathUri
                                v
                      ExecutorFileSystem
                                |
                                +--> plugin.json
                                +--> manifest resources
  ```
  
  This PR stops at the shared selected-plugin representation. The next two
  PRs remove the remaining host-path projections in the skill and MCP
  consumers.
  
  ## Stack
  
  1. #29614 — add lexical `PathUri` containment.
  2. #29620 — share URI-native manifest path resolution.
  3. **This PR** — keep selected plugin roots and resources URI-native.
  4. #29626 — load executor skills without host path conversion.
  5. #29628 — resolve executor MCP working directories without host path
  conversion.

• Propagate safety buffering treatment metadata (#29473)

  ## Summary
  
  - read the request-scoped safety-buffering treatment from HTTP response
  headers and per-turn WebSocket metadata through one shared header parser
  - combine that treatment with Responses API safety-buffering signals
  - propagate `showBufferingUi` and nullable `fasterModel` through the
  existing `model/safetyBuffering/updated` app-server notification
  - update the app-server documentation and generated JSON and TypeScript
  schemas
  
  The public implementation contains no model mapping or real model
  identifier. Tests and protocol examples use generic `current-model` and
  `faster-model` placeholders only.
  
  ## Dependencies
  
  - server-side treatment evaluation:
  https://github.com/openai/openai/pull/1060247
  - initial Responses API safety-buffering propagation:
  https://github.com/openai/codex/pull/29371
  - Codex App UI: https://github.com/openai/openai/pull/1057789
  
  ## Validation
  
  - Codex API tests: 129 passed
  - focused Codex core safety-buffering integration test passed
  - app-server protocol tests passed after regenerating schema fixtures
  - Clippy fix and repository formatting completed successfully
  
  The broader app-server run compiled all changed crates and completed

• mcp: accept foreign absolute cwd for remote stdio (#29493)

  ## Why
  
  Remote stdio MCP servers can run in an environment whose path convention
  differs from the Codex host. A Windows cwd such as
  `C:\Users\openai\share` is absolute for the executor but was rejected by
  a POSIX orchestrator.
  
  Built on #29501, now merged, which only clarifies the host-native
  `PathUri` constructor name.
  
  ## What changed
  
  - Deserialize MCP cwd values as `LegacyAppPathString` so config does not
  apply host path rules.
  - Interpret that spelling as host-native for local launches and convert
  it to `PathUri` at executor launch.
  - Skip host filesystem and command resolution checks for remote stdio in
  `codex doctor`.
  - Add host-independent config and executor-boundary coverage using the
  foreign path convention for each test platform.
  
  ## Validation
  
  - `just test -p codex-utils-path-uri -p codex-config -p codex-mcp -p

  - `just test -p codex-cli -p codex-rmcp-client` (372 passed)

• feat(core): store turn_id on ResponseItem metadata (#28360)

  ## Description
  
  This PR is a followup to https://github.com/openai/codex/pull/28355 and
  starts assigning `internal_chat_message_metadata_passthrough.turn_id` to
  durable Responses API items created during a turn.
  
  The goal is that those items keep the `turn_id` that introduced them
  when Codex resends stateless HTTP context, reconstructs history for
  resume/fork paths, or reuses websocket response state.
  
  ## What changed
  
  - Set `internal_chat_message_metadata_passthrough.turn_id` when missing
  as response items enter durable history, initial/replacement history,
  inter-agent communication history, and local compaction summaries.
  - Preserve existing item turn IDs instead of overwriting them during
  persistence, resume reconstruction, compaction, forked history, and
  websocket incremental reuse.
  - Keep `compaction_trigger` fieldless because it is a request control,
  not a durable response item.
  - Update focused history/request assertions and fixtures for stateless
  requests, websocket incrementals, compaction, thread injection, prompt
  debug, and related CI coverage.

• [plugins] Add dark-mode logo metadata (#29488)

  Adds additive dark-mode plugin logo metadata across manifests, remote
  catalogs, and the app-server protocol while keeping uninstalled Git
  listings free of synthetic local paths.
  
  Supersedes #28945. This replacement uses an upstream branch so trusted
  CI can use the repository-provided remote Bazel configuration.
  
  ## Current state
  
  Plugin interfaces expose only the default logo asset. Clients therefore
  cannot select a dedicated dark-mode logo even when a plugin provides
  one.
  
  ## What this PR changes
  
  - Adds nullable `logoDark` and `logoUrlDark` fields to
  `PluginInterface`.
  - Resolves local `interface.logoDark` assets and maps remote
  `logo_url_dark` values.
  - Removes path-backed interface assets, including `logoDark`, from
  uninstalled Git fallback listings until the plugin has a real local
  root.
  - Updates the bundled plugin validator and manifest reference.
  - Regenerates the app-server JSON schemas and TypeScript types.
  
  Local manifests expose `interface.logoDark` as a package-relative asset
  path. Remote catalog responses expose `logo_url_dark`. These values map
  into separate app-server fields so clients can preserve local-path and
  remote-URL handling.
  
  ## Risk
  
  The fields are additive and nullable, so existing clients retain their
  current logo behavior. The main risks are an incomplete mapping path or
  exposing a synthetic local path for an uninstalled Git plugin.
  Local-manifest, remote-catalog, fallback-listing, protocol
  serialization, and app-server integration tests cover those paths.
  
  Spiciness: 2/5
  
  ## Testing
  
  - `just write-app-server-schema`
  - `just fmt`
  - Regression test first failed with `logo_dark` resolved to
  `/assets/logo-dark.png`, then passed after the fallback-listing fix.
  - `just test -p codex-core-plugins` (267 tests passed)
  - `just test -p codex-app-server 'suite::v2::plugin'` (114 tests passed)
  - `just test -p codex-app-server-protocol -p codex-core-plugins -p
  codex-plugin -p codex-skills` (517 tests passed before the follow-up)
  - `just test -p codex-tui plugin` (47 tests passed)
  - Validated a local plugin manifest containing `interface.logoDark` with
  the bundled validator.
  
  ## Manual verification
  
  Create a local plugin with both `interface.logo` and
  `interface.logoDark`, then call `plugin/list` or `plugin/read`. Confirm
  the response contains separate `logo` and `logoDark` paths. For a remote
  catalog entry, confirm `logoUrlDark` is populated from `logo_url_dark`.
  For an uninstalled Git marketplace entry, confirm path-backed interface
  assets remain absent until installation.
  
  Issue: N/A - coordinated maintainer change.

• permission profiles: expose availability to clients (#26678)

  ## Why
  
  `permissionProfile/list` currently advertises every built-in and
  configured profile even when effective enterprise requirements prevent
  selecting it. That forces each client to reconstruct policy from
  lower-level requirement fields, which is easy to miss and difficult to
  keep consistent.
  
  The catalog should remain complete so clients can explain that an option
  was disabled by an administrator, while also reporting whether each
  profile is selectable.
  
  ## What
  
  - Add an `allowed` field to each permission profile summary.
  - Build a shared catalog from the effective config and current
  requirements, including `allowed_sandbox_modes`, `allowed_permissions`,
  and filesystem restrictions.
  - Use the shared catalog in app-server and the TUI so disallowed
  profiles remain visible but cannot be selected.
  - Use the canonical `:danger-full-access` profile ID in the TUI.
  - Update the app-server schemas, API documentation, behavioral tests,
  and TUI snapshots.
  
  ## Scope
  
  This PR targets `main` directly and is independent of #24852. It
  preserves the current behavior where built-in profiles are constrained
  by sandbox-mode requirements and `allowed_permissions` applies to
  configured profiles.
  
  ## Testing
  
  - `just test -p codex-core
  permission_profile_catalog_marks_profiles_disallowed_by_requirements`
  - `just test -p codex-app-server permission_profile_list`
  - `just test -p codex-app-server-protocol`

  - `just fix -p codex-core`
  - `just fix -p codex-app-server-protocol`

• Allow ChatGPT accounts without email (#28991)

  # Summary
  
  Codex required every ChatGPT account to have an email address. A
  service-account personal access token can return valid account metadata
  without one, so PAT login failed while decoding the metadata response.
  
  This change makes email optional in the account metadata type that owns
  it and preserves that absence through authentication, provider account
  state, the app-server API, generated clients, and TUI bootstrap.
  Existing accounts with email addresses keep the same behavior.
  
  ## Behavior-changing call sites
  
  | Call site | Behavior after this change |
  | --- | --- |
  | `login/src/auth/personal_access_token.rs` | PAT metadata accepts a
  missing or null email and retains `None`. |
  | `agent-identity/src/lib.rs` | Agent Identity JWT claims accept an
  omitted email. |
  | `login/src/auth/storage.rs` and `login/src/auth/agent_identity.rs` |
  Stored and managed Agent Identity records carry `Option<String>`.
  Deserialization maps the legacy empty-string sentinel to `None`. |
  | `login/src/auth/manager.rs` | `get_account_email` returns the stored
  option, and managed identity bootstrap no longer converts `None` to an
  empty string. |
  | `model-provider/src/provider.rs` and `protocol/src/account.rs` | A
  ChatGPT provider account requires a plan type but may carry no email. |
  | `app-server-protocol/src/protocol/v2/account.rs` | `account/read`
  keeps the `email` field on the wire and returns `null` when the account
  has no email. Generated TypeScript and JSON schemas describe a required,
  nullable field. |
  | `sdk/python/src/openai_codex/generated/v2_all.py` | The generated
  Python `ChatgptAccount` model accepts `None` for email. |
  | `tui/src/app_server_session.rs` | Email-less ChatGPT accounts
  bootstrap normally, keep external feedback routing, omit account-email
  telemetry, and display the plan in account status. |
  
  ## Design decisions
  
  - Missing email remains `None` at every layer. The code never uses an
  empty string as a substitute.
  - The app-server response includes `"email": null` instead of omitting
  the field. Clients retain a stable response shape.
  - Plan type remains required for provider account state. This change
  relaxes only the email assumption.
  
  ## Testing
  
  Tests: affected test targets compile, scoped Clippy and formatting pass,
  a focused TUI snapshot covers plan-only account status, real
  before/after PAT login smoke covers metadata without email, app-server
  smoke covers `account/read` with `email: null`, and a regression smoke
  covers an existing email-bearing PAT. Unit tests run in CI.
  
  ## Evidence
  
  Visual smoke evidence will be attached here.

• core: rename metadata -> internal_chat_message_metadata_passthrough (#28968)

  ## Description
  This PR cuts Codex over from generic `ResponseItem.metadata` (introduced
  here: https://github.com/openai/codex/pull/28355) to
  `ResponseItem.internal_chat_message_metadata_passthrough`, which is the
  blessed path and has strongly-typed keys.
  
  For now we have to drop this MAv2 usage of `metadata`:
  https://github.com/openai/codex/pull/28561 until we figure out where
  that should live.

• Simplify multi-agent mode controls (#29324)

  ## Why
  
  Multi-agent delegation policy was split across `multiAgentMode`,
  `features.multi_agent_mode`, and `usage_hint_enabled`. These controls
  could disagree: a requested mode could be downgraded by the feature
  flag, and disabling usage hints also disabled mode instructions.
  
  Some clients also need multi-agent tools without adding
  delegation-policy text to model context. The previous two-mode API could
  not express that directly.
  
  ## What changed
  
  `multiAgentMode` is now the only live delegation-policy control:
  
  | Mode | Behavior |
  | --- | --- |
  | `none` | Keep multi-agent tools available without adding mode
  instructions. |
  | `explicitRequestOnly` | Only delegate after an explicit user request.
  |
  | `proactive` | Delegate when parallel work materially improves speed or
  quality. |
  
  - new threads default to `explicitRequestOnly`; omitting the mode on
  later turns keeps the current value
  - thread start, resume, fork, and settings responses always report the
  concrete current mode instead of `null`
  - mode selection remains sticky across turns and resume
  - usage-hint text no longer controls whether mode instructions apply
  - `features.multi_agent_mode` and `usage_hint_enabled` remain accepted
  as ignored compatibility settings so existing configs continue to load
  - app-server documentation and generated schemas describe the three-mode
  API
  
  ## Tests
  
  - `just test -p codex-core multi_agent_mode`
  - `just test -p codex-core multi_agent_v2_config_from_feature_table`
  - `just test -p codex-core spawn_agent_description`

• Propagate safety buffering events to app-server clients (#29371)

  Responses API safety buffering metadata currently stops at the transport
  boundary, so app-server clients cannot render the in-progress safety
  review state.
  
  This change:
  - decodes and deduplicates `safety_buffering` metadata from Responses
  API SSE and WebSocket events without suppressing the original response
  event
  - emits a typed core event containing the requested model plus backend
  use cases and reasons
  - forwards that event as `turn/safetyBuffering/updated` through
  app-server v2 and updates generated protocol schemas
  - keeps the side-channel event out of persisted rollouts and turn timing
  
  This supports the Codex Apps buffering UX and depends on the Responses
  API backend work in https://github.com/openai/openai/pull/1044569 and
  https://github.com/openai/openai/pull/1044571.
  
  Validation:
  - focused `codex-core` safety-buffering integration test passes
  - `cargo check -p codex-core -p codex-app-server -p
  codex-app-server-protocol`
  - `just fix -p codex-api -p codex-protocol -p codex-core -p

• Add indexed web search mode (#28489)

  ## Summary
  
  - Add `web_search = "indexed"` alongside `disabled`, `cached`, and
  `live`.
  - Use that same resolved mode for both hosted and standalone web search.
  - For hosted search, send `index_gated_web_access: true` with external
  web access enabled only when `indexed` is selected.
  - For standalone search, preserve the existing boolean wire values for
  existing modes (`cached` maps to `false` and `live` to `true`) and send
  `"indexed"` only for `indexed`; `disabled` keeps the tool unavailable.
  - Carry the mode through managed configuration requirements and
  generated schemas.
  
  ## Why
  
  Indexed search provides a middle ground between cached-only search and
  unrestricted live page fetching. Search queries can remain live while
  direct page fetches are limited to URLs admitted by the server.
  
  The existing `web_search` setting remains the single source of truth, so
  hosted and standalone executors cannot drift into different access
  modes. Without an explicit `indexed` selection, the existing
  model-visible tool and request shapes are unchanged.
  
  ```toml
  web_search = "indexed"
  
  [features]
  standalone_web_search = true
  ```
  
  ## Validation
  
  - `just fmt`
  - `just test -p codex-api` (`126 passed`)
  - `just test -p codex-web-search-extension` (`7 passed`)
  - `just test -p codex-core
  code_mode_can_call_indexed_standalone_web_search` (`1 passed`)
  - Focused configuration, hosted request, standalone request, and
  managed-requirement coverage is included in the PR; remaining suites run
  in CI.
  
  The full workspace test suite was not run locally.

• Expose thread-level multi-agent mode (#28792)

  ## Why
  
  Once multi-agent mode can be selected per turn, clients also need to
  choose the initial selection when creating a thread and observe that
  selection through lifecycle and settings APIs.
  
  The selected value is intentionally distinct from the effective
  model-visible value: no client selection is represented as `null`, even
  though an eligible multi-agent v2 turn derives `explicitRequestOnly` as
  its effective default.
  
  ## What changed
  
  - Add the optional experimental `thread/start.multiAgentMode` parameter
  and pass it through thread creation.
  - Preserve an omitted initial value as an unset selection rather than
  eagerly storing `explicitRequestOnly`.
  - Apply an explicit `thread/start` selection to the first turn through
  the session configuration established at thread creation.
  - Restore the latest persisted effective mode as the selected baseline
  on cold resume when rollout history contains one.
  - Inherit the optional selected mode from a loaded parent when creating
  related runtime threads.
  - Return the current selected `multiAgentMode` from `thread/start`,
  `thread/resume`, `thread/fork`, and thread settings, using `null` when
  no mode is selected.
  - Keep lifecycle reporting independent from model capability and feature
  eligibility; core turn construction remains responsible for calculating
  and persisting the effective mode.
  
  ## Not covered
  
  - Clearing an existing loaded-session selection back to unset through
  `turn/start`; omitted or `null` currently retains the session's
  selection.
  - A TUI control, slash command, or `config.toml` preference.
  
  ## Verification
  
  - `CARGO_INCREMENTAL=0 just test -p codex-app-server-protocol`
  - `CARGO_INCREMENTAL=0 just test -p codex-app-server multi_agent_mode`
  
  The focused app-server coverage verifies explicit `thread/start`
  initialization, first-turn prompting, nullable reporting for an omitted
  selection, and retention of selections that are not currently
  runtime-eligible.
  
  ## Stack
  
  Stacked on #28685. This PR contains only the thread initialization and
  lifecycle/settings API layer.

• Add per-turn multi-agent mode (#28685)

  ## Why
  
  Multi-agent v2 currently carries an explicit-request-only delegation
  rule in its static usage hint. That provides a safe default, but it
  prevents clients from selecting proactive delegation per turn without
  changing static guidance or rewriting prior model context.
  
  This change makes delegation mode a session selection that can be
  updated through `turn/start`, while deriving the effective model-visible
  mode separately for each turn. Eligible multi-agent v2 turns remain
  explicit-request-only unless proactive mode is both selected and
  enabled.
  
  ## What changed
  
  - Add the experimental `turn/start.multiAgentMode` parameter with
  `explicitRequestOnly` and `proactive` values. Omission retains the
  loaded session's current optional selection.
  - Add the default-off `features.multi_agent_mode` feature gate. Eligible
  multi-agent v2 turns use the selected mode when enabled; an unset
  selection or disabled gate resolves to `explicitRequestOnly`.
  - Treat mode prompting as inapplicable for multi-agent v1 and other
  unsupported session configurations, producing no multi-agent mode
  developer message rather than rejecting the turn.
  - Move the explicit-request-only rule out of the static v2 usage hint
  and into a bounded, tagged developer context fragment.
  - Emit the effective mode in initial context and only when that
  effective mode changes on later turns.
  - Persist the effective mode in `TurnContextItem` as the durable
  baseline for resume and context-update comparisons.
  
  Historical rollout items are not rewritten. Later mode developer
  messages establish the current rule incrementally.
  
  ## Not covered
  
  - Initial selection through `thread/start` and selected-mode reporting
  from thread lifecycle/settings APIs; those are isolated in the stacked
  #28792.
  - A TUI control or slash command for selecting the mode.
  - Persisting a preferred mode to `config.toml`; selection remains
  session/turn scoped.
  - Changes to multi-agent concurrency limits, tool availability, or model
  catalog capability declarations.
  - Rewriting historical rollout prompt items. Cold resume restores the
  latest persisted effective mode when available while leaving historical
  developer messages intact.
  
  ## Verification
  
  - `CARGO_INCREMENTAL=0 just test -p codex-core multi_agent_mode`
  - Focused app-server coverage verifies that `turn/start.multiAgentMode`
  produces proactive developer instructions for an eligible v2 turn.
  
  ## Stack
  
  Followed by #28792, which adds `thread/start` initialization and
  lifecycle/settings observability.

• [codex] Assign response item IDs when recording history (#28814)

  ## Why
  
  Client-created response items enter history without IDs, so their
  identity is lost across rollout persistence and resume. IDs should be
  assigned once at the history-recording boundary, while IDs returned by
  the server must remain unchanged.
  
  The Responses API validates item IDs using type-specific prefixes.
  Locally generated IDs therefore use the matching prefix plus a
  hyphenated UUIDv7, keeping them valid while distinguishable from
  server-generated IDs. Because this changes persisted history and
  provider request shapes, the behavior is opt-in behind the
  under-development `item_ids` feature. Compaction triggers remain request
  controls whose API shape does not accept an ID.
  
  ## What changed
  
  - Register the disabled-by-default `item_ids` feature and expose it in
  `config.schema.json`.
  - Make supported optional `ResponseItem` IDs serializable and expose
  them in the generated app-server schemas.
  - When `item_ids` is enabled, assign an ID during conversation-history
  preparation if an item has no ID.
  - Generate type-prefixed, hyphenated UUIDv7 IDs using the Responses API
  item conventions.
  - Preserve existing server IDs without rewriting them.
  - Persist assigned IDs in rollouts and include them in subsequent
  Responses requests.
  - Remove the unsupported ID field from `CompactionTrigger` and document
  why it has no ID.
  - Add integration coverage for enabled ID persistence, preservation of
  server IDs, and omission of generated IDs while the feature is disabled.
  
  `prepare_conversation_items_for_history` is the single response-item ID
  allocation boundary.

• Always use AVAS for realtime WebRTC calls (#28856)

  ## Summary
  
  - Remove the realtime `architecture` selector from core protocol,
  app-server protocol, config parsing, generated schemas, and callers.
  - Always create WebRTC realtime calls with the AVAS query params:
  `intent=quicksilver&architecture=avas`.
  - Keep direct websocket realtime behavior on the existing config/default
  path, while WebRTC starts without an explicit version now default to
  realtime v1 because AVAS requires v1.
  
  ## Notes
  
  - WebRTC realtime now means AVAS. If a caller explicitly asks to start
  WebRTC with realtime v2, Codex rejects that request because the AVAS
  WebRTC path only supports realtime v1. Websocket realtime is separate
  and can still use realtime v2.
  - The old `[realtime] architecture = "realtimeapi" | "avas"` config knob
  is removed. Local configs that still set it will need to delete that
  line.
  - Some app-server tests that were only trying to exercise realtime v2
  protocol behavior now use websocket transport, because WebRTC is
  intentionally locked to AVAS/v1. Separate WebRTC tests cover the AVAS
  query params, v1 startup, SDP flow, and sideband join.
  
  ## Validation
  
  - Merged fresh `origin/main` at `83e6a786a2`.

• [codex] Support assistant realtime append text (#28836)

  ## Why
  
  Frontend realtime voice continuity needs to replay a tiny
  previous-session overlap as actual conversation items, including
  assistant text. The app-server `thread/realtime/appendText` API already
  carries a role through to the Rust realtime websocket layer, but the
  shared role enum only accepted `user` and `developer`.
  
  ## What Changed
  
  - Added `assistant` to `ConversationTextRole` and regenerated the
  app-server schema/type fixtures.
  - Added `output_text` as a realtime conversation content type.
  - Updated realtime websocket item creation so assistant appendText emits
  `content: [{ type: "output_text", text }]`, while user and developer
  continue to emit `input_text`.
  - Updated app-server docs and tests to cover assistant appendText
  alongside the existing developer role behavior.
  
  ## Validation
  
  - `just write-app-server-schema`
  - `just fmt` (first sandboxed attempt failed because `uv` could not
  access `~/.cache/uv`; reran with filesystem access and passed)
  - `just test -p codex-api` passed: 126/126
  - `just test -p codex-app-server-protocol` passed: 239/239, including
  generated JSON/TypeScript fixture checks
  - `just test -p codex-app-server` was started locally but stopped per
  request after unrelated local sandbox/Seatbelt failures (`sandbox-exec:
  sandbox_apply: Operation not permitted`) and one missing local `codex`
  binary failure; CI should be faster and more authoritative for the full
  suite.

• [codex] Add optional IDs to response items (#28812)

  ## Why
  
  `ResponseItem` variants do not have a consistent internal ID shape: some
  variants carry required IDs, some carry optional IDs, and some cannot
  represent an ID at all. The existing fields also use inconsistent serde,
  TypeScript, and JSON-schema annotations. A single enum-level access path
  is needed before history recording can assign and retain IDs.
  
  This PR establishes that internal model only. It intentionally does not
  generate or serialize IDs; allocation and wire persistence are isolated
  in the stacked follow-up.
  
  ## What changed
  
  - Give every concrete `ResponseItem` variant an `Option<String>` ID
  field.
  - Apply the same internal-only annotations to every ID field:
  `#[serde(default, skip_serializing)]`, `#[ts(skip)]`, and
  `#[schemars(skip)]`.
  - Add `ResponseItem::id()` and `ResponseItem::set_id()` as the shared
  accessors.
  - Preserve IDs when history items are rewritten for truncation.
  - Adapt consumers that previously assumed reasoning and image-generation
  IDs were required.
  - Regenerate app-server schemas so the hidden fields are represented
  consistently.
  
  The serde catch-all `ResponseItem::Other` remains ID-less because it
  must remain a unit variant.
  
  ## Test plan
  
  - `cargo check --tests -p codex-core -p codex-api -p codex-rollout-trace
  -p codex-image-generation-extension`
  - `just test -p codex-protocol`
  - `just test -p codex-app-server-protocol`

• [codex] Track plugin install and import telemetry failures (#28731)

  ## Summary
  - Track plugin install failures through the unified
  `codex_plugin_install_failed` event for local installs, remote install
  preflight failures, bundle failures, and remote catalog/backend
  failures.
  - Send classified `error_type` values in plugin install failure
  analytics instead of raw error strings.
  - Stop sending raw external-agent import errors in analytics while
  preserving raw failure details in app-facing import
  notifications/history.
  - Keep raw plugin/migration diagnostics in `tracing::warn!` logs.
  - Keep remote failure plugin names as the existing local placeholder
  (`unknown`) and remove the extra telemetry plugin-name override.
  - Change `ExternalAgentConfigImportParams.source` from a generated enum
  to `string | null`, with legacy `claudeCode` / `claudeCowork` inputs
  normalized to existing analytics values.

• [codex] Restore thread recency with compatible migration history (#28671)

  ## Summary
  
  - Revert #28655, restoring the thread `recencyAt` behavior introduced by
  #27910.
  - Move `threads_recency_at` to migration 0039 so it no longer collides
  with `external_agent_config_imports` at version 0038.
  - Repair databases that already applied the recency migration as version
  38 by moving the matching migration-history row to version 39 before
  SQLx validation. The current version-38 migration can then apply
  normally.
  
  ## Validation
  
  - `just test -p codex-state
  migrations::tests::repairs_recency_migration_that_was_applied_as_version_38`
  - `just test -p codex-state -p codex-rollout -p codex-thread-store -p
  codex-app-server-protocol -p codex-tui`: 3,439 passed; six TUI tests
  could not open the machine's existing read-only incident database at
  `~/.codex/sqlite/state_5.sqlite`.
  - `just fix -p codex-state`
  - `just fmt`
  - Verified that state migration versions are unique.

• Scope command approvals by execution environment (#28738)

  ## Why
  
  Command approval cache keys included the command and working directory,
  but not the execution environment. An approval for `/workspace` locally
  could therefore be reused for the same command and path on an executor.
  
  ## What changed
  
  - Include the selected environment ID in shell and unified-exec approval
  cache keys.
  - Carry that ID through the normal command approval request so clients
  can show which environment is being approved.
  - Expose the environment through app-server as a required nullable
  `environmentId` and show it in the inline TUI approval prompt.
  - Keep older recorded approval events compatible when the environment is
  absent.
  
  For example, `echo ok` in local `/workspace` and `echo ok` in executor
  `/workspace` now produce different approval keys and separate prompts.
  
  ## Scope
  
  This PR does not change network approvals, Guardian review actions, MCP
  elicitation, full-screen TUI rendering, or environment-ID validation.
  Remote `shell_command` execution itself remains in #28722; this PR only
  makes its approval key environment-aware.

• [ez][codex-rs] Support apps._default.default_tools_approval_mode (#27965)

  [from codex]
  
  ## Summary
  
  - add `default_tools_approval_mode` to `[apps._default]` and expose it
  through app-server v2 `config/read`
  - apply it after managed, per-tool, and per-app approval settings,
  before the built-in `auto` fallback
  - document the precedence, regenerate config/app-server schemas, and add
  unit plus end-to-end approval coverage
  
  ## Configuration
  
  ```toml
  [apps._default]
  default_tools_approval_mode = "prompt"
  ```
  
  The effective precedence is managed requirements, tool-specific
  `approval_mode`, app-specific `default_tools_approval_mode`,
  `apps._default.default_tools_approval_mode`, then `auto`.
  
  ## Test plan
  
  - `just write-config-schema`
  - `just write-app-server-schema`
  - `just write-app-server-schema --experimental`
  - `just test -p codex-core app_tool_policy`
  - `just test -p codex-core mcp_turn_metadata`
  - `just test -p codex-config`

• Add join key for MAv2 inter-agent messages (#28561)

  ## Summary
  This keeps inter-agent communication on the existing raw response item
  path and adds a join key for MAv2 tool calls.
  
  MAv2 `spawn_agent`, `send_message`, and `followup_task` now stamp the
  originating tool call id into `ResponseItemMetadata.source_call_id` on
  the raw `ResponseItem::AgentMessage`. App-server clients can join that
  raw item back to the existing tool/activity event by call id, while
  using the raw agent message's existing sender, receiver, and content
  fields.
  
  No new app-server `ThreadItem` or notification type is added.
  
  ## Tests
  - `just fmt`
  - `just write-app-server-schema`
  - `just test -p codex-protocol`
  - `just test -p codex-app-server-protocol`
  - `just test -p codex-core

• Revert thread recencyAt for sidebar ordering (#28655)

  ## Why
  
  Revert #27910 to remove the newly introduced thread `recencyAt`
  persistence and API behavior from `main`.
  
  ## What changed
  
  This reverts commit `fac3158c2a783095768076489815f361fa9b0db4`,
  including the state migration, thread-store propagation, app-server API
  surface, generated schemas, and related tests.
  
  ## Validation
  
  Not run before opening; relying on CI for the initial fast signal.

• Add thread recencyAt for sidebar ordering (#27910)

  ## Summary
  
  Add a server-owned `recencyAt` timestamp and `recency_at` thread-list
  sort key for product recency ordering while preserving the existing
  meaning of `updatedAt` as the latest persisted thread mutation.
  
  This is the server-side alternative to #27697. Rather than narrowing
  `updatedAt`, clients can sort the sidebar by `recency_at` and continue
  treating `updatedAt` as mutation time.
  
  Paired Codex Apps PR:
  [openai/openai#1024599](https://github.com/openai/openai/pull/1024599)
  
  ## Contract
  
  - `recencyAt` initializes when a thread is created.
  - A turn start advances `recencyAt` monotonically.
  - Commentary, agent output, tool results, token/accounting updates, turn
  completion, archive, unarchive, resume, and generic metadata writes do
  not advance it.
  - `updatedAt` retains its existing behavior and continues to advance for
  persisted thread mutations.
  - Current servers populate `recencyAt`; the response field is optional
  in generated TypeScript so clients connected to older servers can fall
  back to `updatedAt`.
  - Filesystem-only fallback uses existing updated/mtime ordering when
  SQLite is unavailable.
  
  ## Persistence and compatibility
  
  Migration 0038 adds second- and millisecond-precision recency columns,
  backfills them from the existing updated timestamp, creates list
  indexes, and includes an insert trigger so older binaries writing to a
  migrated database seed recency without causing later mutations to
  advance it.
  
  Generic metadata upserts preserve existing recency values. Turn-start
  updates use a dedicated monotonic touch, and process-local allocation
  keeps millisecond cursor values unique. State DB list, search, read,
  filtered-list repair, rollout fallback propagation, and app-server
  conversions all carry the new field.
  
  ## API
  
  `Thread` responses include:
  
  ```ts
  recencyAt?: number
  ```
  
  `thread/list` and `thread/search` accept:
  
  ```json
  { "sortKey": "recency_at" }
  ```
  
  Generated TypeScript and JSON schemas are included.
  
  ## Validation
  
  - `just test -p codex-state` — 146 passed
  - `just test -p codex-rollout` — 69 passed
  - `just test -p codex-thread-store` — 81 passed
  - `just test -p codex-app-server-protocol` — 231 passed
  - Focused app-server list ordering, response mapping, archive/unarchive,
  and resume lifecycle tests passed
  - Scoped `just fix` for state, rollout, thread-store,
  app-server-protocol, and app-server
  - `just fmt`
  - `git diff --check`
  - Independent correctness, simplicity, elegance, security, and
  test-quality reviews; actionable ordering, lifecycle, query-projection,
  and timestamp-uniqueness findings were addressed

• app-server: preserve target-native environment cwd (#28146)

  ## Why
  
  app-server may run on a different OS from the selected exec-server
  environment. Parsing that environment’s cwd with the Codex host’s path
  rules prevents thread startup.
  
  ## What
  
  Carry environment cwd values as `LegacyAppPathString` at the app-server
  boundary and `PathUri` internally. Existing tool-call schemas and
  relative-path behavior stay host-native; remaining local-only consumers
  convert explicitly and leave follow-up TODOs.
  
  The Wine integration test verifies app-server can start a thread and
  complete an ordinary turn with a Windows environment cwd from Linux.
  
  ## Validation
  
  - `bazel test //codex-rs/core/tests/remote_env_windows:smoke-test
  --test_output=errors`
  - focused app-server environment-selection and protocol schema tests
  - scoped Clippy for `codex-core` and `codex-app-server-protocol`

• Clarify model-generated and legacy app path types (#28577)

  ## Why
  
  `ApiPathString` kind of implies that it can be used anywhere we pull a
  path out of JSON, but it's not really appropriate for tool arguments
  when the model might generate relative paths.
  
  Prefer `String` for model-generated paths and we can handle the
  conversion per feature for now and define a shared abstraction later if
  it makes sense.
  
  # What
  
  Rename `ApiPathString` to `AppLegacyPathString` to clarify its role.
  
  Expand the `path-types` skill to tell the model to leave tool args as
  bare strings.
