• [core] debounce current-time reminders by elapsed time (#29659)

  ## Summary
  - rename `reminder_interval_model_requests` to
  `reminder_interval_seconds`
  - read the configured time provider before every model request and
  inject a reminder only after the configured number of seconds has
  elapsed
  - preserve immediate first delivery and forced delivery after compaction
  changes the context window
  
  ## Tests
  - `just test -p codex-core current_time_reminder`

• Namespace multi-agent v2 tools under collaboration (#29067)

  ## Summary
  
  Multi-agent v2 tools now use the fixed `collaboration` namespace when
  namespace tools are available. This keeps the model-visible hint and the
  actual tool surface aligned around `functions.collaboration.*`, without
  exposing an unshipped namespace knob to users.
  
  The PR also removes the old `features.multi_agent_v2.tool_namespace`
  config/schema surface, updates the MAv2 test fixtures for namespaced
  calls, and fixes stale `TurnContext.features` references that were
  breaking `codex-core` builds.
  
  ## Changes
  
  - Expose MAv2 tools under `collaboration` instead of relying on a
  configurable namespace.
  - Remove `tool_namespace` from MAv2 TOML config, resolved config,
  validation, schema, and tests.
  - Update tool-planning and integration fixtures to assert or emit
  namespaced MAv2 tool calls.
  - Read feature state through `TurnContext.config.features` in the
  multi-agent mode context paths.
  
  ## Testing
  
  - `just write-config-schema`
  - `just test -p codex-features`

• [codex] reject remote images at app-server ingress (#29419)

  ## Stack
  
  Stacked on #29417. Review and land that PR first.
  
  ## Summary
  
  - reject HTTP(S) image URLs in the handlers for `turn/start` and
  `turn/steer`
  - validate `thread/inject_items` after its existing
  JSON-to-`ResponseItem` conversion, so each item is deserialized once
  - turn invalid dynamic-tool image responses into the existing
  unsuccessful text fallback; the model receives the validation message as
  the function output
  - leave `thread/resume.history` compatible with legacy history; #29417
  replaces remote images before model input
  - continue accepting inline data URLs and `localImage` inputs
  - keep this policy in app-server; this PR does not add a shared protocol
  API or change core image preparation
  
  ## Test plan
  
  - `just test -p codex-app-server -E
  'test(/request_handlers_reject_remote_image_urls|dynamic_tool_remote_image_response_becomes_model_visible_error|dynamic_tool_call_round_trip_sends_content_items_to_model|turn_start_tracks_turn_event_analytics|standalone_image_edit_uses_recent_pathless_image/)'`

• 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.

• [codex] replace remote images with model-visible error text (#29417)

  ## What
  
  This PR will extend the existing centralized image-preparation path to
  replace HTTP(S) image inputs with a model visible error message. It
  won't "ruin" and break existing rollouts, but it will deprecate support
  for the pathway. App server clients should no longer use HTTP image urls
  if they'd like to upgrade.
  
  The HTTP image url pathway is currently resolved in the responsesapi. It
  is slow and not reccomended.
  
  ## Behavior
  
  - HTTP(S) image URL: replace with `input_text`
  - data URL: use the existing decode and resize path
  - other image URL schemes: leave unchanged
  
  This intentionally does not change app-server ingress. That validation
  remains a follow-up.
  
  ## Test plan
  
  - `just test -p codex-core -E
  'test(/image_preparation|prepares_image_failures_before_history_insertion|prepares_resumed_history_before_installing_it|responses_lite_prepares_images/)'`
  — 7 passed

• [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.

• [codex] fetch featured IDs for remote plugins (#29485)

  ## Summary
  
  - fetch featured plugin IDs when the loaded catalog includes
  `openai-curated-remote`
  - extend the existing remote marketplace regression test to cover the
  featured IDs response
  
  ## Why
  
  When the remote plugin catalog was enabled, app-server loaded
  `openai-curated-remote` but skipped `/plugins/featured` because the
  request processor only fetched featured IDs for the local
  `openai-curated` marketplace. As a result, the desktop app could not
  render the backend-curated remote featured set.
  
  This keeps the existing local behavior and also returns the curated
  ranking for remote plugins.
  
  ## Test plan
  
  - `just fmt`
  - `git diff --check`
  - `just test -p codex-app-server
  plugin_list_includes_remote_marketplaces_when_remote_plugin_enabled`

• 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`

• 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.

• remove flag for image preparation (#29429)

  ## What
  
  - make Fjord's centralized response-item image preparation unconditional
  for new and resumed history
  - have local user images and `view_image` outputs always defer decoding
  and resizing to that path
  - retain `resize_all_images` as an ignored, removed compatibility key
  for released clients
  - delete the flag-off producer paths and obsolete policy-specific tests
  
  ## Why
  
  Centralized preparation is now the intended image path. Keeping the
  runtime feature checks also kept two image-processing implementations
  alive and allowed client config to select the legacy behavior.
  
  This is a clean replacement for #28975, rebuilt from the latest `main`.
  
  ## How
  
  `prepare_response_items` now runs whenever items enter history and
  whenever persisted history is reconstructed. Producers emit deferred
  image data, so malformed images become the existing model-visible
  placeholder instead of failing the session at the producer.

• fix(core): restore thread_source in x-codex-turn-metadata (#29455)

  ## Description
  
  Restore `thread_source` in `x-codex-turn-metadata`.
  
  Inadvertently removed `thread_source` from `x-codex-turn-metadata` in
  https://github.com/openai/codex/pull/27122 - didn't realize it was a
  top-level thread app-server API field, not passed in
  `responsesapi_client_metadata`.
  
  This also reserves the key so `responsesapi_client_metadata` cannot
  override it.

• 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`

• Persist session IDs across thread resume (#29327)

  ## Summary
  
  A cold-resumed subagent kept its durable thread ID but could receive a
  new session ID, splitting one agent tree across multiple sessions after
  a restart.
  
  Persist the root session ID in every rollout `SessionMeta`, carry it
  through thread creation, and restore it before initializing the resumed
  `Session` and `AgentControl`.
  
  ## Behavior
  
  For a nested agent tree:
  
  ```text
  root session R
    parent thread P
      child thread C
  ```
  
  The child rollout stores:
  
  ```text
  session_id:       R
  parent_thread_id: P
  id:               C
  ```
  
  After a cold resume, the child still belongs to root session `R` while
  its immediate parent remains `P`. The integration coverage uses distinct
  values for all three IDs so it catches restoring the session from
  `parent_thread_id`.
  
  ## Legacy rollouts
  
  Previous rollouts have `id` but no `session_id`. `SessionMetaLine`
  deserialization treats a missing `session_id` as `id`, keeping those
  files readable, listable, and resumable. When a legacy subagent is
  resumed through its root, that synthesized child ID no longer overrides
  the inherited root-scoped `AgentControl`. New rollouts always persist
  the explicit root session ID.

• Add config toggles for orchestrator skills and MCP (#28942)

  ## Why
  
  Orchestrator-provided skills and Codex Apps MCP tools add model-visible
  instructions, resources, and tools beyond the local workspace. Hosts
  need config-level switches to disable those orchestrator-owned surfaces
  independently, without disabling regular skills or regular MCP servers.
  
  ## What changed
  
  - Adds `[orchestrator.skills].enabled` and `[orchestrator.mcp].enabled`
  config entries, both defaulting to `true`.
  - Includes the new settings in `config.schema.json` and in the config
  lock so resolved thread configuration preserves the same orchestrator
  exposure decisions.
  - Threads `orchestrator.skills.enabled` through the app-server skills
  extension so disabled orchestrator skills do not expose the `skills`
  namespace or inject orchestrator skill context.
  - Gates Codex Apps MCP exposure, app instructions, and app auth
  eligibility on `orchestrator.mcp.enabled` while leaving non-Codex-Apps
  MCP tools available.
  - Updates the thread-manager sample config to disable both
  orchestrator-owned surfaces.
  
  ## Verification
  
  - Added config parsing, loading, defaulting, and schema coverage for the
  new settings.
  - Added MCP exposure coverage that `orchestrator.mcp.enabled = false`
  removes Codex Apps tools while preserving regular MCP tools.
  - Added app-server coverage that `orchestrator.skills.enabled = false`
  prevents orchestrator skill tools, prompts, and resource reads from
  reaching the model turn.

• 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.

• [3/3] app-server: configure environment connection timeout (#29025)

  ## Why
  
  Remote environments registered through `environment/add` currently use
  the fixed 10-second WebSocket connection timeout. Slow-starting
  executors need a caller-selected connection window, but this should not
  add retry policy or couple exec-server behavior to Core’s
  `deferred_executor` feature.
  
  Make the timeout an optional part of the existing experimental request.
  Existing clients continue using the current default, while callers that
  know an executor may take longer can request a larger window explicitly.
  
  Depends on #28683.
  
  ## What changed
  
  - Add optional `connectTimeoutMs` to `EnvironmentAddParams` and document
  it in the app-server README.
  - Pass the optional timeout through `EnvironmentRequestProcessor` into
  one `EnvironmentManager::upsert_environment()` path; the manager applies
  the existing default when it is omitted.
  - Preserve the existing single-attempt lifecycle. The configured value
  controls WebSocket connection and handshake time for both initial
  connection and later reconnects; initialization retains its separate
  timeout.
  - Add an app-server integration test that sends the real JSON-RPC
  request and verifies a stalled handshake observes the requested timeout.
  
  ## Test plan
  
  - `just test -p codex-app-server-protocol`
  - `just test -p codex-exec-server`
  - `just test -p codex-app-server
  environment_add_applies_connect_timeout`
  
  ## Rollout
  
  This is additive and does not enable `deferred_executor`. Callers should
  send a non-default timeout only after a compatible app-server is
  deployed; omitted or `null` values retain the existing 10-second
  default.

• [codex] Support protected resource OAuth discovery (#29022)

  ## Why
  
  Plugin-install preflight and the actual OAuth login flow used different
  discovery implementations. Preflight had a Codex-specific implementation
  that only queried authorization-server metadata on the MCP host, while
  login already used the upstream `rmcp` Rust MCP SDK. As a result,
  servers that advertise a separate authorization server through RFC 9728
  Protected Resource Metadata were classified as OAuth-unsupported during
  plugin installation, so login was skipped.
  
  ## What changed
  
  - delegate plugin-install OAuth discovery to
  `rmcp::transport::AuthorizationManager`, the same implementation used by
  the login flow
  - let `rmcp` follow Protected Resource Metadata first and perform direct
  RFC 8414 authorization-server discovery when protected-resource
  discovery does not yield usable metadata
  - retain Codex's existing HTTP headers, timeout, `no_proxy` behavior,
  and scope normalization around that discovery
  - add unit coverage and a pure-MCP plugin-install integration test that
  proves the protected-resource path reaches OAuth client registration
  
  This only changes shared MCP OAuth discovery. App declarations and
  `appsNeedingAuth` behavior are unchanged.
  
  ## Verification
  
  - `just test -p codex-rmcp-client auth_status`
  - `just test -p codex-app-server plugin_install_starts_mcp_oauth`
  - real plugin-install smoke test with an isolated `CODEX_HOME`: both
  DigitalOcean MCP servers started OAuth callback listeners, while Linear
  continued to start its existing direct-discovery OAuth flow

• 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`.

• core: load AGENTS.md from foreign environments (#28958)

  ## Why
  
  Make it possible to load AGENTS.md from remote exec-servers whose OS is
  different than app-server.
  
  ## What
  
  - keep `AGENTS.md` discovery and provenance as `PathUri`, with
  root-aware parent and ancestor traversal
  - expose lifecycle instruction sources as legacy app-server path strings
  in events while retaining `PathUri` internally
  - preserve and test mixed POSIX and Windows paths in model context and
  TUI status output
  - cover remote Windows loading end to end by seeding the Wine prefix
  through host filesystem APIs
  - fix bug in `PathUri`'s parent() implementation that would erase
  Windows drive letters

• [codex] Preserve remote plugin download status errors (#28863)

  ## Summary
  
  - preserve the original HTTP status when a remote plugin bundle download
  returns a non-success response
  - retain at most 8 KiB of the error response body and annotate
  truncation or body-read failures
  - add regression coverage for an oversized error response
  
  ## Root cause
  
  The non-success response path reused the normal size-limited body
  reader. When an error response exceeded 8 KiB, that reader returned
  `DownloadTooLarge` before the code constructed `DownloadStatus`, masking
  the upstream HTTP status and response context.
  
  ## Impact
  
  Remote plugin installation failures now retain the actionable upstream
  HTTP status without allowing unbounded error bodies into logs.
  
  ## Validation
  
  - `just test -p codex-app-server
  plugin_install_preserves_status_when_remote_bundle_error_body_is_too_large`

• Emit Trusted MCP App Identity on Tool-Call Items (#27132)

  ## Summary
  
  - Add optional `appContext` to app-server MCP tool-call items with
  trusted `connectorId`, `linkId`, and `mcpAppResourceUri` metadata.
  - Preserve that context across tool-call events, persisted history,
  reconnects, and thread resume.
  - Keep the deprecated top-level `mcpAppResourceUri` temporarily for
  client migration.
  
  The consumer contract is `{ appContext: { connectorId, linkId,
  mcpAppResourceUri }, tool }`.
  
  ## Validation
  
  - Full GitHub Actions suite passes, including CLA, Bazel tests, clippy,
  release builds, and argument-comment lint.

• [codex] Remove hardcoded app ID filters (#28947)

  ## Summary
  
  - remove the duplicated originator-specific connector ID denylists
  - stop filtering connector directory/accessibility results and
  live/cached Codex Apps MCP tools by hardcoded connector ID
  - remove the now-unused `codex-login` dependency from
  `codex-utils-plugins`
  - update regression coverage so formerly blocked connector IDs are
  preserved
  
  ## Why
  
  The client-side policy was duplicated across crates, used opaque IDs
  without ownership or expiry information, and could drift between app
  listing and MCP tool behavior. Server-provided visibility,
  authorization, plugin discoverability, accessibility, enabled-state
  handling, and consequential-tool approval templates remain unchanged.
  
  ## Validation
  
  - `just fmt`
  - `just bazel-lock-update`
  - `just bazel-lock-check`
  - `git diff --check`
  - confirmed the final diff contains no hardcoded denylist symbols
  
  A targeted `codex-mcp` test build spent an unusually long time in local
  compilation/linking. Its first attempt exposed a test-only `PartialEq`
  assertion issue, which was corrected. A follow-up non-linking `cargo
  check -p codex-mcp --tests` was still running when this draft was
  opened; CI should provide the complete Rust validation.

• Add app-server current-time impl (varlatency 3/n) (#28835)

  ## What
  
  Server should request:
  
  ```
  {
    "id": 42,
    "method": "currentTime/read",
    "params": {
      "threadId": "11111111-1111-1111-1111-aaaaafdc2c11"
    }
  }
  ```
  
  Client should respond with something like:
  
  ```rust
  {
    "id": 42,
    "result": {
      "currentTimeAt": 1781717655
    }
  }
  ```
  
  ## Why
  
  Sessions configured with `clock_source = "external"` need a
  thread-specific external time source before inference. The system clock
  remains the default production provider.

• Synchronize realtime notification test requests (#28946)

  ## What
  
  Deliver the scripted realtime notification batch after the assistant
  text append request instead of after the preceding developer text append
  request.
  
  ## Why
  
  The batch ends with an upstream error that closes the realtime
  conversation. When it is emitted after the developer append, it races
  the subsequent assistant append: the app-server RPC can acknowledge the
  append before its downstream WebSocket send completes, and the test
  intermittently observes three requests instead of four.
  
  Making the fake server wait for the assistant append before emitting the
  terminal batch establishes the ordering the test asserts without sleeps
  or production-code changes.
  
  ## Validation
  
  - `git diff --check`
  - CI (the failure is timing-dependent and most reproducible in the
  Windows Bazel shard)

• Fix goal-first live threads missing from thread/list (#28808)

  Fixes #28263.
  
  ## Why
  
  When a thread starts with `/goal`, the goal extension can update SQLite
  goal state before the thread has any user-turn rollout items.
  `thread/list` and `thread/search` rely on persisted listing metadata, so
  a goal-first live thread could be absent from app-server listings after
  restart even though the goal itself existed.
  
  This regressed when goal handling moved out of core: the core path wrote
  the goal update through the live thread rollout path, while the
  extension-backed app-server path only updated goal state and emitted the
  live notification.
  
  ## What
  
  - Add `GoalSetOutcome::thread_goal_updated_item()` so the goal extension
  owns the canonical `ThreadGoalUpdated` rollout item shape.
  - Expose a narrow `CodexThread::append_rollout_items()` helper that
  appends through the live thread and keeps derived SQLite metadata in
  sync.
  - When app-server sets a goal on an active live thread, persist the goal
  update through that live-thread path.
  - Add an app-server regression test that starts a live thread with
  `thread/goal/set` and verifies it appears in state-DB-only
  `thread/list`.
  
  ## Verification
  
  - `env -u CODEX_SQLITE_HOME just test -p codex-app-server

• unified-exec: retain PathUri in command events (#28780)

  ## Why
  
  App-server must report command events containing foreign-platform paths
  without changing existing client or rollout path-string formats.
  
  ## What changed
  
  - retain `PathUri` through exec command begin/end events
  - convert cwd values to `LegacyAppPathString` at the app-server
  compatibility boundary
  - drop command actions with foreign paths and log them
  - serialize rollout-trace cwd values using their inferred native path
  representation
  - restore Wine coverage for retained Windows cwd values and successful
  completion

• [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] control automatic realtime handoff delivery (#27986)

  ## What
  
  Built on the realtime speech-control plumbing merged in #27917.
  
  - Add optional `codexResponseHandoffPrefix` to `thread/realtime/start`.
  - Apply that prefix only to automatic V1 commentary sent through
  `conversation.handoff.append`; final answers remain unprefixed.
  - Add opt-in `clientManagedHandoffs`. When true, core suppresses
  automatic response handoffs and completion output so delivery is
  controlled by explicit client append APIs.
  - Preserve existing automatic behavior by default.
  `codexResponsesAsItems: true` continues to select item routing when
  client-managed mode is disabled.
  
  ## Why
  
  Voice clients need two delivery policies: automatic background context
  with silent commentary instructions and fully client-owned handoffs.
  Phase-aware prefixing keeps routine commentary silent without
  suppressing the final answer, while client-managed mode lets an app
  decide exactly which updates to append.
  
  ## Validation
  
  - `just fmt`
  - `cargo test -p codex-app-server-protocol
  serialize_thread_realtime_start`
  - `RUST_MIN_STACK=16777216 cargo test -p codex-core --test all
  conversation_handoff_persists_across_item_done_until_turn_complete`
  - `RUST_MIN_STACK=16777216 cargo test -p codex-app-server --test all

  webrtc_v1_final_automatic_handoff_omits_silent_prefix`
  - `cargo build -p codex-cli --bin codex`
  - Local Codex Apps compatibility check: 43 focused webview tests passed,
  and a live voice session routed through the source-built app-server.
  
  The explicit `RUST_MIN_STACK` avoids a macOS Tokio test-worker stack
  overflow seen with the default test environment.

• [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.

  preflight failures, bundle failures, and remote catalog/backend
  failures.
  - Send classified `error_type` values in plugin install failure

  - 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.

• 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.

• app-server: keep the model cache warm (#28699)

  ## Why
  
  The app server is long-lived, but its shared model cache otherwise
  refreshes only when a caller needs it. Once the five-minute cache
  expires, starting a thread or calling `model/list` can wait for
  `/models` on the request path.
  
  Refresh the cache in the background before it expires so foreground
  callers normally use fresh local state.
  
  ## What changed
  
  - Start an app-server worker that refreshes models immediately and then
  every three minutes using the existing models-manager API.
  - Hold only a weak reference to the models manager between refreshes, so
  the worker does not extend its lifetime.
  - Stop scheduling refreshes when the app-server lifecycle handle is shut
  down or dropped. A refresh already in progress is allowed to finish.
  - Adjust affected app-server test fixtures to distinguish the background
  `/models` probe from the connection they are testing.
  
  The existing models-manager cache, refresh strategies, auth handling,
  ETag behavior, and concurrency semantics are unchanged.
  
  ## Testing

• 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

• [codex] [3/4] Activate endpoint plugin recommendations (#27704)

  Summary\n- Await endpoint recommendation selection while constructing

  the bounded contextual user fragment, tool exposure, and exact install
  validation.\n- Keep recommendation selection ephemeral: do not persist
  recommendation state in or gate resumed threads on prior context.\n-
  Hide the legacy list tool in endpoint mode and preserve legacy discovery
  unchanged when the endpoint is disabled or unavailable.\n- Keep remote
  plugin and connector app identities out of model-visible context and
  attach them only to Codex-owned elicitation metadata.\n\nStack\n- 3/4,
  based on #28400.\n- Endpoint client and cache: #28399.\n- Generalized

• 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`

• [codex] exec-server: stream files in chunks (#28354)

  ## Why
  
  `fs/readFile` buffers the entire file in one response, which makes large
  remote reads expensive and prevents callers from applying backpressure.
  We need an opt-in streaming path with bounded block sizes while
  preserving the existing single-call API for small and sandboxed reads.
  
  ## What changed
  
  - Add `ExecServerClient::stream`, returning a named `FileReadStream`
  that implements `futures::Stream` and yields immutable 1 MiB byte
  blocks.
  - Add internal `fs/open`, `fs/readBlock`, and `fs/close` RPCs.
  `fs/readBlock` accepts an explicit offset and length.
  - Keep unsandboxed files open between block reads, cap open handles per
  connection, and clean them up on EOF, error, stream drop, explicit
  close, or connection shutdown.
  - Reject platform-sandboxed streaming opens instead of turning the
  one-shot sandbox helper into a persistent server. Existing `fs/readFile`
  behavior is unchanged.
  
  ## Testing
  
  - `just test -p codex-exec-server`
  - Integration coverage for 1 MiB chunking, exact block-boundary EOF,
  sandbox rejection, and continued reads from the opened file after path
  replacement.
  - Handle-manager coverage for non-sequential offsets, variable block
  lengths, the 128-handle limit, and capacity release after close.

• [codex] expose Bedrock credential source in account/read (#27751)

  ## Why
  
  `account/read` currently reports only `type: "amazonBedrock"`, so
  clients cannot distinguish a Codex-managed Bedrock API key from
  credentials supplied by AWS. The app UI needs that distinction to render
  the appropriate account state without duplicating provider-auth logic.
  
  Credential-source selection belongs to the Bedrock model provider
  because it already owns the precedence between managed Bedrock auth and
  the external AWS credential path. This builds on #27443 and #27689.
  
  ## What changed
  
  - Added `AmazonBedrockCredentialSource` with `codexManaged` and
  `awsManaged` values.
  - Included the selected credential source in
  `ProviderAccount::AmazonBedrock` and the app-server `Account` response.
  - Made `AmazonBedrockModelProvider::account_state()` classify the source
  from its managed-auth state.
  - Regenerated the app-server JSON and TypeScript schemas.
  - Updated app-server account documentation and downstream TUI matches.
  
  `codexManaged` means the provider found a managed Bedrock API key.
  `awsManaged` identifies the provider's external AWS credential path; it
  does not assert that the AWS credential chain has been validated.
  
  ## Testing
  
  - Added model-provider coverage for Codex-managed precedence and
  AWS-managed fallback.
  - Added app-server protocol serialization coverage for both wire values.
  - Added app-server integration coverage for both `account/read`
  responses.
  - `just test -p codex-protocol -p codex-model-provider -p
  codex-app-server-protocol` (497 tests passed).
  
  After rebasing onto #27711, the `codex-app-server` test target compiled
  past the image-generation `PathUri` migration. Local linking was then
  interrupted by disk exhaustion (`No space left on device`).

• [codex] Record external agent import results (#28396)

  ## Summary
  - restore `externalAgentConfig/import/progress` notifications while
  keeping `externalAgentConfig/import/completed` as the must-deliver event
  - persist completed external-agent config imports in state DB by
  `importId`, including concrete success/failure details for config,
  AGENTS.md, skills, plugins, MCP servers, subagents, hooks, commands, and
  sessions
  - add `externalAgentConfig/import/readHistories` so clients can recover
  persisted import results after missing the live completion notification
  - include `errorType` on import failures in protocol
  responses/notifications and persisted DB JSON so future code can
  classify failures without another wire/storage shape change
  
  ## Validation
  - `git diff --check`
  - `just test -p codex-state external_agent_config_imports`
  - `just test -p codex-app-server-protocol`
  - `CODEX_SQLITE_HOME=/private/tmp/codex-app-server-sqlite-read-details
  just test -p codex-app-server
  external_agent_config_import_sends_completion_notification_for_sync_only_import`
  
  Also ran earlier broader checks before publishing:

• [codex] Use expect in integration tests (#28441)

  The workspace denies `clippy::expect_used` in production. Although
  `clippy.toml` allows `expect` in tests, Bazel Clippy compiles
  integration-test helper code in a way that does not receive that
  exemption, which encouraged verbose `unwrap_or_else(... panic!(...))`
  and equivalent `match`/`let else` forms.
  
  This allows `clippy::expect_used` once at each integration-test crate
  root (including aggregated suites and test-support libraries), then
  replaces manual panic-based Result and Option unwraps with
  `expect`/`expect_err`. Standalone `tests/*.rs` files remain their own
  crate roots. Intentional assertion and unexpected-variant panics remain
  unchanged, and the production `expect_used = "deny"` lint remains in
  place.
  
  The cleanup is mechanical and net-negative in line count.

• [codex] Add interruptible sleep tool (#28429)

  ## Why
  
  Models sometimes need to pause briefly while waiting for external work,
  but using a shell command for that delay ties the wait to a process and
  does not naturally resume when new turn input arrives.
  
  ## What changed
  
  - add a built-in `sleep` tool behind the under-development `sleep_tool`
  feature
  - accept a bounded `duration_ms` argument, matching the millisecond
  convention used by unified exec
  - end the sleep early when either steered user input or mailbox input
  arrives
  - include elapsed wall-clock time in completed and interrupted outputs
  - emit a dedicated core `SleepItem` through `item/started` and
  `item/completed`
  - expose the sleep item as app-server v2 `ThreadItem::Sleep` and retain
  it in reconstructed thread history
  - regenerate the configuration schema for the new feature flag
  - regenerate app-server JSON and TypeScript schema fixtures
  
  ## Test plan
  
  - `just test -p codex-core sleep_tool_follows_feature_gate`
  - `just test -p codex-core any_new_input_interrupts_sleep`
  - `just test -p codex-app-server-protocol`

• [codex] Make plugin details capability aware (#27958)

  ## Summary
  
  Makes plugin details/read flows capability-aware so auth-filtered plugin
  surfaces report the same usable app/MCP/skill shape as the marketplace
  and install flows.
  
  ## Validation
  
  Not run; this change was rebased onto the current plugin auth stack and
  pushed as a draft PR.
  
  **Manual test**
  1. set up a local marketplace with a plugin that has both app and mcp
  declarations
  
  ```
  // .app.json
  {
    "apps": {
      "linear": {
        "id": "some_id"
      }
    }
  }
  
  ```
  
  ```
  // .mcp.json
  {
    "mcpServers": {
      "linear": {
        "type": "http",
        "url": "https://mcp.linear.app/mcp",
        "oauth_resource": "https://mcp.linear.app/mcp"
      },
      "linear2": {
        "type": "http",
        "url": "https://mcp.linear2.app/mcp",
        "oauth_resource": "https://mcp.linear2.app/mcp"
      }
    }
  }
  ```
  
  2a. **login in with api key** and observe plugin details page which
  shows no apps (note we don't show "app not available due to api key log
  in as there's no way to differentiate between no apps and app without
  substitute mcp exists" without significantly more code changes, i've
  separated this to a follow up if we want that behaviour.

• [codex] Load API curated marketplace by auth (#28383)

  ## Summary
  - choose the local OpenAI curated marketplace manifest based on auth:
  Codex backend auth gets the existing marketplace, direct provider auth
  gets `api_marketplace.json`
  - include Bedrock API key auth in the direct-provider API marketplace
  path
  - safely skip the API marketplace when `api_marketplace.json` is absent
  
  ## Validation
  - `just fmt`
  - `git diff --check origin/main...HEAD`
  - CI should run the full validation
  
  ## Manual Testing
  
  ### - New api marketplace not available for API key sign
  1. Safely not display anything from api marketplace
  <img width="1161" height="289" alt="Screenshot 2026-06-15 at 21 37 43"
  src="https://github.com/user-attachments/assets/a5f16642-8a20-4ac1-a0de-1274a4c7b5b2"
  />
  
  ### - New api marketplace for API key sign in
  1. Setup api_marketplace.json
  ```
  {
    "name": "openai-curated",
    "interface": {
      "displayName": "Codex official"
    },
    "plugins": [
      {
        "name": "linear",
        "source": {
          "source": "local",
          "path": "./plugins/linear"
        },
        "policy": {
          "installation": "AVAILABLE",
          "authentication": "ON_INSTALL"
        },
        "category": "Productivity"
      }
    ]
  }
  ```
  
  2. Log in with API key, observe that only the defined plugin from
  api_marketplace.json is available from "Codex Official" (outside of
  local testing marketplaces)
  <img width="1167" height="446" alt="Screenshot 2026-06-15 at 21 16 53"
  src="https://github.com/user-attachments/assets/7cf61477-d826-4ef6-bc05-0a23ac1c0259"
  />
  
  also checked functionality on codex app
  
  ### - SiWC users 
  Still uses 'default' marketplace.json and renders all plugins
  <img width="1171" height="502" alt="Screenshot 2026-06-15 at 21 40 25"
  src="https://github.com/user-attachments/assets/d212ea9b-0aa5-470b-8ea4-450efe65bb2b"
  />
  
  also checked functionality on codex app
  
  
  ## Notes
  - `just test -p codex-core-plugins` was started locally before splitting
  branches, but I stopped relying on local tests per follow-up and left
  final validation to PR CI.

• Add a toggle for realtime startup context (#28405)

  ## Summary
  - Add `includeStartupContext` to realtime start requests so callers can
  explicitly skip Codex startup context while keeping the backend prompt
  - Thread the new flag through protocol types, request processing, and
  realtime session config
  - Update app-server docs and coverage for the new default and opt-out
  behavior
  
  ## Testing
  - Added protocol serialization coverage for `includeStartupContext`
  - Added realtime integration coverage for starting a session with
  startup context disabled

• Add realtime speech append control (#27917)

  ## Why
  
  Realtime voice harness tuning needs app-side control over what backend
  Codex text is spoken. Backend orchestrator text is written for a reading
  UI, so automatically speaking every preamble, progress update, or final
  assistant message can make the realtime voice model too chatty.
  
  For experimentation, clients need two simple controls: keep app/client
  text-item injection on the existing item-create path, and add an
  explicit speakable path that app code can call only when it wants
  realtime to speak. Automatic Codex output also needs an opt-in way to
  switch from the protocol's default speakable path to regular realtime
  items, with a caller-provided prefix so prompt wording can be tuned
  outside core.
  
  The default remains unchanged: if a client omits the new start fields
  and never calls `appendSpeech`, automatic backend output continues down
  the existing speakable path for the selected realtime protocol.
  
  ## What Changed
  
  - Adds experimental `thread/realtime/appendSpeech` for app-provided
  speakable text.
  - Keeps existing `thread/realtime/appendText` as the item-create API for
  app-provided realtime text items.
  - Adds `codexResponsesAsItems` / `codex_responses_as_items` on
  `thread/realtime/start` to send automatic Codex responses with
  `conversation.item.create` instead of the protocol's default speakable
  output path.
  - Adds `codexResponseItemPrefix` / `codex_response_item_prefix` so
  clients can prepend experiment instructions to those automatic Codex
  response items.
  - Keeps literal `conversation.handoff.append` routing scoped to the v1
  speakable path; v2 default speech uses its item/function-output plus
  `response.create` behavior.
  - Removes the earlier public silent-context API and hardcoded
  silent-context prefix.
  - Updates realtime tests to cover default automatic speakable behavior,
  opt-in automatic item-create behavior, and explicit `appendSpeech`
  behavior.
  
  ## Validation
  
  - `cargo check -p codex-core -p codex-app-server -p codex-api`
  - `just test -p codex-app-server realtime_conversation`
  - `just test -p codex-core realtime_conversation` (50/51 passed in the
  filtered parallel run; the lone failure passed when rerun in isolation)
  - `just test -p codex-core
  conversation_mirrors_assistant_message_text_to_realtime_handoff`
  - `just test -p codex-api
  e2e_connect_and_exchange_events_against_mock_ws_server`
  - `just fix -p codex-core`
  - `just fix -p codex-app-server`
  - `cargo build -p codex-cli`
