• Prepare managed network sandbox context (#29456)

  ## Why
  
  Managed network configures commands to use local HTTP and SOCKS proxies.
  For commands delegated to the exec server, the proxy environment and the
  sandbox policy were prepared separately. On macOS, that meant a command
  could receive `HTTPS_PROXY=http://127.0.0.1:43123` while Seatbelt still
  denied access to port `43123`.
  
  ## What changed
  
  `NetworkProxy` now prepares the command environment and sandbox context
  together from the same runtime snapshot:
  
  ```text
  Prepared managed network
  ├── command environment: HTTPS_PROXY=http://127.0.0.1:43123
  └── sandbox context: allow outbound to 127.0.0.1:43123
  ```
  
  That context travels with remote exec requests. The exec server
  preserves the managed proxy and CA environment, and macOS Seatbelt
  allows only the prepared loopback proxy ports without enabling broad
  network access or local binding.
  
  The protocol field is optional and the existing enforcement flag remains
  in place, preserving compatibility with callers that do not send the new
  context.

• app-server: document thread and turn IDs are UUID7 (#27714)

  It's actually a very nice property that these are UUID7s, so documenting
  them so we think twice before changing it away from UUID7s in the

• Handle additional tools in rollout persistence metrics (#29669)

  ## Why
  
  The rollout persistence metrics added on current `main` exhaustively
  match `ResponseItem`, but omit `ResponseItem::AdditionalTools`. That
  prevents `codex-rollout` and downstream targets from compiling across
  Cargo and Bazel builds.
  
  ## What
  
  Map `ResponseItem::AdditionalTools` to the `response.additional_tools`
  metric label, consistent with the existing exact-variant labels.
  
  ## Validation
  
  - `just test -p codex-rollout` (76 passed)
  - `just fix -p codex-rollout`

• [codex] Handle additional tools in rollout persistence metrics (#29672)

  ## Summary
  
  Handle `ResponseItem::AdditionalTools` in rollout persistence metrics.
  
  The persistence metrics match was added after the `AdditionalTools`
  variant and omitted it, causing release builds to fail with a
  non-exhaustive pattern error. This assigns the item the
  `response.additional_tools` metrics label.
  
  Release failure:
  https://github.com/openai/codex/actions/runs/28043786727/job/83016608475
  
  ## Validation
  
  - `just fmt`
  - `just test -p codex-rollout` (76 passed)

• core: use turn-owned world state for inline compaction (#29527)

  ## Why
  
  Follow-up to #29249 and its [compaction review
  thread](https://github.com/openai/codex/pull/29249#discussion_r3455055101).
  
  During a turn, environment readiness can change between sampling
  requests. Inline compaction must render the same model-visible
  `WorldState` used by the request it follows. Rebuilding that state
  during compaction can observe a newer environment, make replacement
  history disagree with what the model saw, and suppress the next
  environment update.
  
  ## What changed
  
  - Make `run_turn` own the current `Arc<WorldState>` and replace it only
  between sampling requests.
  - Build each state from an explicitly chosen environment snapshot, diff
  deferred-executor steps against the turn-owned state, and retain the
  latest state in `ContextManager` only for cross-turn and resume
  tracking.
  - Pass the exact turn-owned state into inline compaction and explicit
  new-context-window replacement.
  - Carry that state with
  `InitialContextInjection::BeforeLastUserMessage`, so replacement context
  and its stored baseline cannot come from different snapshots.
  - Remove obsolete state-recapture helpers and ambiguous TurnContext-only
  WorldState builders.
  - Add an integration test that moves an environment from starting to
  ready during a paused turn, triggers compaction, and verifies the next
  request receives the readiness update exactly once.
  
  ## Test plan
  
  - `just test -p codex-core
  deferred_executor_compaction_preserves_then_updates_environment_once`
  - `just test -p codex-core process_compacted_history`
  - `just test -p codex-core mid_turn_continuation_compaction`
  - `just test -p codex-core build_initial_context`
  - `just test -p codex-core

• Shut down superseded MCP managers on refresh (#29608)

  ## Summary
  
  MCP refresh replaced the published connection manager without shutting
  down the manager it superseded. If another task retained that old
  manager, its stdio MCP processes stayed alive and accumulated across
  refreshes.
  
  Atomically swap in the refreshed manager, then explicitly shut down the
  exact manager returned by the swap. Add a process-level regression test
  that retains the old manager during refresh and verifies its stdio
  process exits while the replacement remains available.
  
  ## Context
  
  Explicit cleanup was lost when manager publication moved to `ArcSwap`.
  Dropping the old manager is not a reliable shutdown boundary because
  active callers can retain its `Arc` and underlying client process
  handles.

  `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

• [codex] Instrument rollout persistence bytes (#29498)

  - Add 1%-sampled rollout persistence metrics that report per-item and
  per-thread JSON byte totals before and after filtering when metrics
  export is enabled.
  - Tag each item with its exact response or event variant, including
  nested turn-item kinds for conditionally persisted completion events, so
  aggregate cloud-storage impact can be estimated by policy choice.

• Update vulnerable Hono and fast-uri dependencies (#29650)

  ## Summary
  
  - Pin `hono` to 4.12.25, the first patched release for the recent Hono
  security advisories.
  - Pin `fast-uri` to 3.1.1 to fix the percent-encoded path traversal
  vulnerability.
  - Refresh `pnpm-lock.yaml` with only those dependency updates.
  
  `hono` 4.12.25 is used instead of the newer 4.12.27 because the
  repository requires dependencies to be at least seven days old.

• Update rmcp to 1.8.0 (#29634)

  ## Summary
  
  - Update `rmcp` and `rmcp-macros` from 1.7.0 to 1.8.0.
  - Adapt to the new shared `peer_info` return type.
  - Box OAuth status discovery at the MCP boundary to keep the expanded
  future type from overflowing Rust's trait recursion limit.
  
  This brings in custom OAuth HTTP client support from
  [modelcontextprotocol/rust-sdk#908](https://github.com/modelcontextprotocol/rust-sdk/pull/908).

• Share resumed rollout history (#28426)

  ## Summary
  
  Resuming a persisted thread currently deep-clones its complete rollout
  history several times. `InitialHistory` is retained for the app-server
  response, copied into thread persistence, and copied again by read-only
  accessors. These copies scale with the complete rollout rather than the
  bounded model context and add measurable latency for large sessions.
  
  This change stores resumed rollout history in `Arc<Vec<RolloutItem>>`.
  Rollout loading wraps the parsed vector once, while app-server response
  construction, session initialization, and thread persistence share it
  through inexpensive `Arc` clones. Read-only history access now returns a
  borrowed slice, and fork paths use `Arc::unwrap_or_clone` where they
  genuinely need mutable ownership. Rollout reconstruction also consumes
  its temporary context instead of cloning the reconstructed model
  history.
  
  The serialized representation remains unchanged. In an artificial 123 MB
  rollout benchmark, sharing resumed history reduced cold resume latency
  by roughly 9–10%. The affected crates compile with their test targets,
  all 80 thread-store tests pass, and the Bazel dependency lock remains
  valid.

• path-uri: add lexical containment (#29614)

  ## Why
  
  Executor-owned paths must stay portable while the orchestrator reasons
  about them. Converting a Windows or remote path to the orchestrator
  host's native path just to check containment breaks that boundary.
  
  ## What changed
  
  - Add lexical containment to `PathUri`.
  - Compare URI authorities and complete path segments, so `plugin-other`
  is not treated as a child of `plugin`.
  - Fail closed for encoded path separators and opaque fallback URIs.
  
  For example:
  
  ```text
  file:///C:/plugins/foo/assets/icon.svg
    is below file:///C:/plugins/foo
  
  file:///C:/plugins/foo2/icon.svg
    is not below file:///C:/plugins/foo
  ```
  
  This is the shared foundation for keeping executor-owned plugin
  resources URI-native without consulting the orchestrator filesystem.

• 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`

• Fix Codex Apps auth elicitation hang (#29615)

  ## Summary
  - Require the reserved Codex Apps MCP server name to be present in the
  connection manager before treating it as host-owned.
  - Update auth elicitation tests to model an installed host-owned Codex
  Apps server without sending startup events to the test session.
  
  ## Why
  PR #29518 replaced the old host-owned flag with a name-only check. That
  made non-host-owned tests with the reserved codex_apps name enter auth
  elicitation and wait forever for a response.

• Stop persisting bridged log events (#29599)

  ## Why
  
  The 0.142.0 persistent-log filter disables target=log, but bridged log
  records are filtered using their original dependency target before
  tracing-log emits them as target=log. This allowed high-volume
  dependency TRACE events to keep reaching SQLite.
  
  This is a follow-up to #28224.
  
  ## What changed
  
  - Reject bridged target=log events inside the SQLite sink before
  formatting or queueing them.

• Allow codex sandbox to consume MCP sandbox state (#29358)

  ## Summary
  
  - let `codex sandbox` accept the JSON value from
  `codex/sandbox-state-meta`
  - require the payload `permissionProfile` instead of falling back to
  ambient permissions
  - reuse the existing macOS, Linux, and Windows launch paths, treating
  external sandbox state conservatively as read-only

• Group Codex Apps client setup (#29583)

  ## Why
  
  `McpConnectionManager::new` classified the Codex Apps server twice: once
  to create its tools cache context and again to select its runtime
  authentication provider. Keeping those decisions separate makes it
  harder to see that they belong to the same server-specific setup path.
  
  ## What changed
  
  - Group Codex Apps cache and authentication setup under one explicit
  branch.
  - Keep regular MCP server setup in the corresponding `else` branch.
  - Limit environment bearer-token inspection to the Codex Apps path where
  it affects runtime authentication.

• Remove redundant Codex Apps cache guard (#29575)

  ## Why
  
  Codex Apps cache writes are already restricted to Codex Apps call paths:
  startup invokes the helper only from the Codex Apps branch, and hard
  refresh operates on the reserved Codex Apps server directly. Rechecking
  the server name inside the cache helper duplicates that classification
  and leaves the helper with an argument that cannot change valid
  behavior.
  
  ## What changed
  
  - Remove the redundant server-name check and parameter from the cache
  writer.
  - Rename the helper to `write_codex_apps_tools_cache` to reflect its
  narrower contract.
  - Update production and test callsites to use the simplified API.

• Handle additional tools in image URL validation (#29577)

  ## Why
  
  `ResponseItem::AdditionalTools` was added without updating app-server
  image URL validation. The exhaustive match therefore prevents app-server
  and downstream targets from compiling on `main`.
  
  ## What changed
  
  Treat `AdditionalTools` like the other response items that cannot
  contain input-image URLs.

• Centralize Codex Apps client handling (#29528)

  ## Why
  
  Codex Apps-specific behavior is currently distributed across cache
  helpers, startup, tool conversion, and model-visible annotation. Each
  layer independently checks the reserved server name, which obscures the
  boundary between trusted host-owned connector metadata and regular MCP
  server data.
  
  Classifying the server once when `AsyncManagedClient` is created gives
  the client a single source of truth and makes the two processing paths
  explicit.
  
  ## What changed
  
  - Record whether an `AsyncManagedClient` represents the Codex Apps
  server at construction time.
  - Route startup cache loading, cache persistence, and cache telemetry
  through the Codex Apps branch.
  - Split uncached tool conversion between Codex Apps normalization and
  regular MCP metadata sanitization.
  - Split model-visible schema and plugin provenance handling along the
  same boundary.
  - Remove redundant server-name guards from helpers that are now called
  only from the Codex Apps branch.
  
  ## Verification
  
  - Preserve behavioral coverage that verifies Codex Apps connector
  metadata and the complete converted `ToolInfo` shape.
  
  ## Stack
  
  Depends on #29518.

• [codex] Use input items for Responses Lite tools (#27946)

  When using Responses Lite, we should all use `additional_tools` and a
  developer item instead of the top level tools array & instructions
  field. This keeps things 1-to-1.
  
  Forced namespacing for _all_ tools will land in a following PR after
  some coordination & fixes in Responses API (around collisions & return
  items).
  
  The goal is to eventually expand the scope of this to _all_ requests
  from codex, but that will require larger coordination across providers &
  slower rollout.

• Remove redundant Codex Apps manager flag (#29518)

  ## Why
  
  Codex Apps server admission is already decided before
  `McpConnectionManager` is constructed. `effective_mcp_servers` and
  `effective_mcp_servers_from_configured` remove the server when the apps
  feature or required authentication is unavailable, so storing the same
  decision on the manager duplicates state that can drift from the
  effective server map.
  
  ## What changed
  
  - Remove `host_owned_codex_apps_enabled` from `McpConnectionManager` and
  its constructor.
  - Identify the host-owned Codex Apps server by its reserved server name
  once it is present in the effective server map.
  - Remove the now-unused flag calculations and constructor arguments from
  production and test callsites.

• [codex] Expose service tier and reasoning effort in OTEL (#29155)

  ## Summary
  
  NVIDIA asked to measure Fast mode usage and reasoning effort from Codex
  CLI OTEL logs. Add the finalized `service_tier` and
  `model_reasoning_effort` to the existing `codex.sse_event`
  `response.completed` record.
  
  This intentionally reuses the existing completion event and leaves
  transport APIs and shared telemetry plumbing unchanged.
  
  ## Testing
  
  - `cargo build -p codex-cli --bin codex`
  - `just test -p codex-core responses_api_emits_api_request_event`
  - End-to-end with the built CLI and a local OTLP/HTTP collector:
  - Fast/high emitted `service_tier=priority` and
  `model_reasoning_effort=high` with token usage.
  - Standard/low omitted `service_tier` and emitted
  `model_reasoning_effort=low` with token usage.

• [codex] Reject unlowered PowerShell AST regions (#24092)

  ## Why
  
  On Windows, Codex uses a PowerShell safe-command classifier to decide
  whether a command is read-only enough to run without additional
  approval. The classifier lowers `EndBlock.Statements` into argv-like
  command words and checks those words against a safelist.
  
  PowerShell can execute code stored elsewhere in the AST. Parameter
  defaults, named blocks, `using` preambles, and top-level `trap` handlers
  are not represented in the lowered statement list. Ignoring those
  regions can make a side-effecting script look like a read-only command.
  
  ## What
  
  Fail closed whenever a PowerShell script contains executable AST content
  that the current lowering does not represent.
  
  ## How
  
  - Return `unsupported` for parameter, dynamic-parameter, begin, process,
  and clean blocks.
  - Return `unsupported` for `using module` and `using assembly`
  preambles.
  - Return `unsupported` for non-empty `EndBlock.Traps` collections.
  - Preserve compatibility with Windows PowerShell 5.1 by looking up
  `CleanBlock` dynamically.
  - Treat `unsupported` as a failure to prove that the command is safe,
  routing it through the normal approval path.
  - Add parser-level and end-to-end regressions for parameter blocks,
  named blocks, using statements, and trap handlers.
  
  This does not make these PowerShell forms invalid or prevent them from
  running. It prevents automatic safe-command approval when the classifier
  cannot account for all executable behavior.
  
  ## Testing
  
  - `just test -p codex-shell-command`
  - Windows CI exercises the parser and end-to-end safe-command
  regressions against a real PowerShell installation.

• 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
  with 1,269 passing tests. Its remaining failures were unrelated
  environment limitations: macOS sandbox application was denied, one
  expected test binary was unavailable, and several existing subprocess
  tests timed out as a result.

• 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
  codex-rmcp-client` (408 passed)
  - `just test -p codex-cli -p codex-rmcp-client` (372 passed)
  - `cargo check --workspace --tests`
  - `just test` (11,311 passed; 43 unrelated environment/timing failures)
  - `just fix -p codex-cli -p codex-config -p codex-core -p codex-mcp -p
  codex-mcp-extension -p codex-rmcp-client -p codex-tui`

• PAC 4 - Add macOS system proxy resolver (#26709)

  ## Summary
  
  Stacked on #26708.
  
  Adds the macOS implementation of the shared system-proxy contract. This
  allows Codex-owned auth clients to use the route macOS selects for each
  auth URL through SystemConfiguration and CFNetwork, including PAC and
  WPAD results.
  
  The `respect_system_proxy` feature is disabled by default, so existing
  client behavior remains unchanged unless explicitly enabled.
  
  ## Implementation
  
  - Adds the macOS-only `system-configuration` dependency to
  `codex-client`.
  - Dispatches system-proxy resolution to `outbound_proxy/macos.rs` on
  macOS.
  - Reads system proxy settings from `SCDynamicStore` and resolves the
  target URL with `CFNetworkCopyProxiesForURL`.
  - Executes PAC URLs and inline PAC JavaScript through a bounded run loop
  with a five-second timeout.
  - Handles `DIRECT`, HTTP proxies, and CFNetwork HTTPS entries using HTTP
  CONNECT; unsupported SOCKS entries map to `UnsupportedProxyScheme`.
  - Builds concrete proxy URLs from host and port entries, including IPv6
  host bracketing.
  - Maps results into the shared `SystemProxyDecision::{Direct, Proxy,
  Unavailable}` contract.
  - Hashes URL-specific cache keys so PAC decisions remain distinct
  without retaining raw request URLs or query strings.
  
  ## End-user behavior
  
  - Disabled/default: existing client behavior is unchanged.
  - Enabled with `[features.respect_system_proxy]`:
    - macOS auth clients honor system proxy configuration, PAC, and WPAD;
    - valid OS/PAC `DIRECT` decisions use a direct connection;
  - unavailable system resolution falls back to explicit environment proxy
  variables, then `DIRECT`, through the shared contract from #26707.
  - Unsupported proxy schemes are not silently translated into another
  route.
  - Custom CA handling remains separate from proxy selection.
  - Known limitation: only the first supported system/PAC candidate is
  used. Subsequent proxy or `DIRECT` candidates are not attempted after a
  connection failure. This matches the current Windows behavior and leaves
  room for future ordered-fallback support.

• Make formatter output quiet on success (#29467)

  ## Why
  
  `just fmt` is quite noisy even on successful runs.
  
  ## What
  
  Only print output when a formatter fails.
  
  - Buffer output from each formatter and print only a failed command and
  its diagnostics.
  - Prefix the `justfile` driver invocations with `@` so Just does not
  echo the command itself.
  - Retain rustfmt stderr on failure and cover silent-success and
  failure-reporting behavior.
  
  ## Validation
  
  - Confirmed `just fmt` and `just fmt-check` both exit successfully with
  empty stdout and stderr.

• chore: improve expired Bedrock credential errors (#28992)

  ## Why
  
  Amazon Bedrock returns a `401 Unauthorized` response containing
  `Signature expired:` when an AWS credential, including a short-lived
  `AWS_BEARER_TOKEN_BEDROCK`, has expired. Codex currently surfaces that
  response as a generic `unexpected status` error, which does not explain
  how to recover.
  
  Environment-provided bearer tokens cannot be refreshed automatically, so
  the error should direct users to refresh their AWS credentials or
  replace or remove the environment token and restart Codex. This
  classification belongs to the Amazon Bedrock provider so similar
  responses from other providers retain their existing behavior.
  
  ## What changed
  
  - Add a synchronous `ModelProvider::map_api_error` hook that defaults to
  the existing provider-neutral API error mapping, and route model
  request, stream, WebSocket, and terminal unauthorized errors through the
  active provider.
  - Override the hook for Amazon Bedrock. After preserving the structured
  status, body, URL, and request metadata, recognize `401` responses
  containing `Signature expired:` and attach actionable credential
  guidance.
  - Keep `codex-protocol` provider-neutral by representing the guidance as
  an optional `user_message`. Error rendering prefers this message while
  continuing to append the URL, request ID, Cloudflare ray, and
  authorization diagnostics.
  - Add model-provider coverage for expired signatures and negative cases,
  core coverage for provider dispatch after unauthorized recovery, and a
  TUI snapshot for the rendered error.
  
  ## Testing
  Tested with a real request with expired bedrock key:

• [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

• TUI Plugin Sharing 4 - cover remote plugin catalog flows (#26704)

  Remote plugin catalogs now span workspace, shared, and local sources, so
  their TUI behavior needs focused regression coverage across loading,
  navigation, actions, and refreshes.
  
  This PR:
  
  - Covers product labels and rendered loading/error states for Workspace,
  Shared with me, Shared with me (link), and Local tabs, including tab
  persistence across refresh and detail navigation.
  - Covers remote/local deduplication, Installed-tab remote detail
  routing, marketplace load-error handling, and disabled install/uninstall
  navigation.
  - Adds a full detail snapshot for local shared-plugin metadata plus
  focused snapshots for marketplace labels and admin-disabled status.
  - Verifies shared plugins remain eligible for mentions and successful
  uninstalls trigger a catalog refresh.

• [codex] Use tool search for MCP tools by default (#29486)

  ## Why
  
  MCP tools were only placed behind `tool_search` when a feature flag was
  enabled or when there were at least 100 tools. That made the model's
  tool flow depend on both rollout configuration and the number of
  installed tools.
  
  The searched-tool flow is now the intended behavior. Making it
  unconditional when the model and provider support it gives every
  supported setup the same behavior and lets us retire the feature flag
  safely.
  
  ## What changed
  
  - Defer all effective MCP tools when `tool_search` and namespaced tools
  are supported.
  - Keep exposing MCP tools directly when search cannot be used, so older
  or unsupported model/provider combinations still work.
  - Mark `tool_search_always_defer_mcp_tools` as removed and ignore old
  configured values.
  - Keep plugin filtering, app-only filtering, file handling, and MCP
  calls working through the searched-tool flow.
  
  ## Why many tests changed
  
  Many tests used to act as if the model could see MCP tools in its first
  request and call them immediately. That is no longer the real flow: the
  model first receives `tool_search`, searches for a tool, receives the
  matching MCP tool, and then calls it in the next request.
  
  The tests therefore needed an extra search step, and checks for tool
  names, descriptions, and input fields had to move from the first request
  to the search result. These are not separate product changes; they make
  the tests follow what the model will actually see after this change. The
  plugin tests still check which tools are allowed and where they came
  from, the file tests still check upload fields and behavior, and the MCP
  round-trip test still checks a successful call from start to finish.
  
  ## Tests
  
  - `just test -p codex-features`
  - Focused `codex-core` tests for MCP exposure and tool planning
  - `just test -p codex-core explicit_plugin_mentions`
  - `just test -p codex-core stdio_server_round_trip`
  - Focused `codex-core` tests for tool search, app-only tools, and MCP
  file uploads

• 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

• core: wrap token budget window context (#29494)

  Token-budget initial context carries thread and context-window lineage
  that the model should treat as one structured context-window block.
  Wrapping it in `<context_window>` makes that boundary explicit while
  preserving the existing window id content.
  
  Before this change, the window identifiers were injected as an untagged
  developer text fragment:
  
  ```text
  Thread id <THREAD_ID>.
  First context window id: <FIRST_WINDOW_ID>
  Current context window id: <WINDOW_ID>
  Previous context window id: <PREVIOUS_WINDOW_ID>
  ```
  
  After this change, the same payload is wrapped as a context-window
  block:
  
  ```text
  <context_window>
  Thread id: <THREAD_ID>
  First context window id: <FIRST_WINDOW_ID>
  Current context window id: <WINDOW_ID>
  Previous context window id: <PREVIOUS_WINDOW_ID>
  </context_window>
  ```
  
  This adds shared `CONTEXT_WINDOW_*_TAG` protocol constants, updates
  `TokenBudgetContext` to render with those markers, treats the new
  wrapper as contextual developer content when mapping history, and
  refreshes the token-budget request-shape assertions and snapshot.
  
  Verification:
  - `just test -p codex-core token_budget`
  - `just test -p codex-core

• [codex] migrate environment context to model world state (#29249)

  ## Why
  
  Environment context is model-visible state, but it is currently
  assembled from transient turn values and diffed through
  environment-specific paths. That makes initial injection, turn-to-turn
  updates, and changes that happen within a turn use different baselines.
  
  This PR introduces the smallest useful model world-state slice:
  environments only, with one in-memory baseline and one renderer for full
  state and diffs.
  
  ## What changed
  
  - Add a typed `WorldState` container whose sections render fragments
  relative to an optional previous value. Full rendering uses the same
  diff path with no previous state.
  - Replace the parallel `EnvironmentContext` representation with an
  `EnvironmentsState` section keyed by environment ID and rendered in
  deterministic order.
  - Preserve the legacy single-environment output while supporting
  multiple environments, starting environments, unavailable tombstones,
  and changes to persisted turn-context values.
  - Store the latest complete `WorldState` on `ContextManager` and use it
  for both turn-boundary and mid-turn environment diffs.
  - Build initial and post-compaction context from the same world-state
  builder, then retain the rendered state as the next baseline.
  - Seed the in-memory baseline from the latest `TurnContextItem` when
  resuming an existing rollout; the world state itself is not serialized.
  - Keep non-world settings updates on their existing path and merge
  rendered world-state fragments at the session consumer.
  
  ## Known limitation
  
  A legacy `TurnContextItem` only reconstructs the primary environment as
  `local`; it cannot faithfully recover a remote-primary environment ID
  after resume. Live state uses the exact environment IDs once a complete
  baseline is established.
  
  ## Test plan
  
  - `just test -p codex-core world_state`
  - `just test -p codex-core record_context_updates`
  - `just test -p codex-core deferred_executor_`
  - `just test -p codex-core build_initial_context`

• [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] Update esbuild to 0.28.1 (#29489)

  ## Why
  
  The TypeScript workspace resolved `esbuild` 0.25.10 transitively through
  the SDK toolchain. `esbuild` 0.28.1 adds integrity verification to the
  Deno binary download path addressed by
  [GHSA-gv7w-rqvm-qjhr](https://github.com/evanw/esbuild/security/advisories/GHSA-gv7w-rqvm-qjhr),
  preventing an attacker-controlled npm registry from supplying an
  executable without a content check.
  
  ## What changed
  
  - Add a root workspace resolution for `esbuild` 0.28.1.
  - Regenerate `pnpm-lock.yaml` so `tsup`, `bundle-require`, and `ts-jest`
  all resolve the patched version.
  
  ## Validation
  
  - Frozen pnpm install, including the SDK's `tsup` build
  - `pnpm --filter @openai/codex-sdk exec jest tests/exec.test.ts
  --runInBand`
  - Confirmed the installed dependency graph contains only `esbuild`
  0.28.1

• Upgrade bundled OpenSSL to 3.6.3 (#29487)

  ## Summary
  
  - upgrade the bundled OpenSSL source from 3.5.5 to 3.6.3
  - update the Bazel `openssl-sys` build dependency to use the upgraded

  - refresh the Bazel module lockfile
  
  ## Why
  
  OpenSSL 3.5.5 is within the affected ranges for security issues fixed in
  later releases. The Rust `openssl-src` wrapper does not currently
  publish OpenSSL 3.5.7, so this moves the vendored Linux musl build to
  the available patched 3.6.3 release.

• [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

  - `git diff --check`
  - `just test -p codex-app-server

• PAC 3 - Add Windows system proxy resolver (#26708)

  ## Summary
  
  Stacked on #26707.
  
  Adds the Windows implementation of the shared system-proxy contract.
  This allows Codex-owned auth clients to use the route Windows selects
  for each auth URL, including explicit PAC configuration, WPAD
  auto-detection, static proxies, and bypass rules.
  
  The `respect_system_proxy` feature is disabled by default, so existing
  client behavior remains unchanged unless explicitly enabled.
  
  ## Implementation
  
  - Adds Windows-only `codex-client` dependencies:
  - `windows-sys` with `Win32_Foundation` and `Win32_Networking_WinHttp`;
    - `sha2` for redacted cache keys.
  - Dispatches system-proxy resolution to `outbound_proxy/windows.rs` on
  Windows.
  - Reads the current-user WinHTTP/IE proxy configuration via
  `WinHttpGetIEProxyConfigForCurrentUser`.
  - Resolves explicit PAC URLs first, then OS-enabled WPAD auto-detection,
  then static proxy and bypass settings.
  - Uses `WinHttpGetProxyForUrl` for PAC/WPAD and maps results into the
  shared `SystemProxyDecision::{Direct, Proxy, Unavailable}` contract.
  - Parses `DIRECT`, `PROXY`, `HTTPS`, and keyed static proxy entries.
  - Treats unsupported schemes such as SOCKS as unavailable so the shared
  resolver can apply its environment-proxy fallback.
  - Handles Windows bypass entries, including `<local>` and host, suffix,
  wildcard, and port matching.
  - Releases WinHTTP-owned strings with `GlobalFree` and closes sessions
  with `WinHttpCloseHandle`.
  - Hashes URL-specific cache keys with SHA-256 so PAC decisions remain
  URL-specific without retaining raw request URLs or query strings.
  
  ## End-user behavior
  
  - Disabled/default: existing client behavior is unchanged.
  - Enabled with `[features.respect_system_proxy]`:
  - Windows auth clients honor explicit PAC configuration, OS-enabled
  WPAD, static proxies, and bypass rules;
    - valid OS/PAC `DIRECT` decisions use a direct connection;
  - unavailable system resolution falls back to explicit environment proxy
  variables, then `DIRECT`, through the shared contract from #26707.
  - Unsupported proxy schemes are not silently translated into a different
  route.
  - Custom CA handling remains separate from proxy selection.
  
  ## Tests
  
  Adds coverage for:
  
  - PAC-style proxy tokens such as `PROXY proxy.internal:8080` and `HTTPS
  proxy.internal:8443`;
  - static WinHTTP proxy entries keyed by target scheme;
  - `DIRECT` and unsupported proxy-token behavior;
  - Windows bypass matching, including `<local>`, wildcard, suffix, and
  port-qualified entries;
  - preserving URL-specific PAC cache decisions without retaining the raw
  URL on Windows.

• [codex-core-plugins] Remote Plugin ID Persisted to File (#27669)

  ## This PR
  
  Remote plugin analytics cannot rely only on the in-memory
  installed-plugin snapshot because that snapshot is refreshed
  asynchronously after startup. This PR persists the authoritative backend
  identity alongside each cached remote plugin bundle so later consumers
  can resolve it without a network request.
  
  ### Behavior
  
  - Store Codex-owned remote installation metadata in an atomic
  `.codex-remote-plugin-install.json` sidecar under the plugin cache root.
  - Use a versioned, snake_case schema:
  
    ```json
    {
      "schema_version": 1,
      "remote_plugin_id": "plugins~Plugin_..."
    }
    ```
  
  - Write the metadata during remote bundle installation.
  - Backfill it when bundle sync finds an already-current cached bundle.
  - Clear it when a generic/local install replaces the cache.
  - Let existing uninstall and stale-cache removal delete it with the
  plugin cache root.
  - Reject unsupported schema versions rather than silently misreading
  future formats.
  
  This PR does not change analytics serialization or event behavior.
  
  ### Review surface
  
  The implementation is limited to four `codex-core-plugins` files:
  
  - `store.rs`: owns the versioned sidecar read/write/remove lifecycle.
  - `remote_bundle.rs`: persists the backend ID after a remote bundle
  install.
  - `remote/remote_installed_plugin_sync.rs`: backfills metadata for an
  already-current cached bundle.
  - Tests cover the storage lifecycle and both remote write paths.
  
  ## Testing / Validation
  
  ### Automated
  
  - `just test -p codex-core-plugins` (268 tests passed)
  - `just fix -p codex-core-plugins` passes with one pre-existing
  `large_enum_variant` warning in `manifest.rs`.
  - Coverage verifies the exact filename and JSON schema, identity
  replacement, local reinstall clearing, uninstall cleanup, remote bundle
  installation, unsupported schema rejection, and installed-plugin sync
  backfill.
  
  ### Live manual validation
  
  Validated the production app-server RPC path with an isolated temporary
  `CODEX_HOME` and the PR-built Codex binary. The app-server communicated
  over stdio and did not bind a port.
  
  Test plugin: `plugins~Plugin_b80dd84519148191a409cde181c9b3d6`
  (`build-macos-apps@openai-curated-remote`).
  
  1. Confirmed `plugin/read` initially reported the plugin uninstalled.
  2. Installed it through `plugin/install` and confirmed version `0.1.4`
  was cached.
  3. Verified
  `$CODEX_HOME/plugins/cache/openai-curated-remote/build-macos-apps/.codex-remote-plugin-install.json`
  was created beside the `0.1.4/` bundle directory with mode `0600` and
  the expected contents:
  
     ```json
     {
       "schema_version": 1,
  "remote_plugin_id": "plugins~Plugin_b80dd84519148191a409cde181c9b3d6"
     }
     ```
  
  4. Deleted only the sidecar, restarted the app-server, and confirmed
  installed-plugin startup sync recreated it with the same contents.
  5. Uninstalled through `plugin/uninstall`, confirmed `plugin/read`
  returned `installed: false`, and verified the local plugin cache root
  was removed.
  6. Restored the account's original uninstalled state and removed the

• chore: advance tungstenite fork pins (#29480)

  ## Why
  
  `openai-oss-forks/tokio-tungstenite` now includes the updated
  `tungstenite` fork revision from
  [openai-oss-forks/tokio-tungstenite#3](https://github.com/openai-oss-forks/tokio-tungstenite/pull/3).
  Codex should consume the merged fork commit and resolve its direct and
  transitive `tungstenite` dependencies to the same revision instead of
  retaining the older pins.
  
  ## What Changed
  
  - Advanced the `tokio-tungstenite` git pin to
  `0e5b2d73aa18dd9f0a50ee9ff199d5aef7594186`.
  - Advanced the `tungstenite` fork pin to
  `4fffad30fe373adbdcffab9545e9e9bf4f2fc19f` and adjusted the patch source
  so the transitive dependency resolves to that revision.
  - Updated `Cargo.lock` and `MODULE.bazel.lock` to match the dependency
  graph.

• Honor startup custom CA bundles with managed MITM (#29014)

  ## Why
  
  When Codex starts with a custom CA override such as
  `SSL_CERT_FILE=/path/to/corp-ca.pem codex`, `rustls-native-certs` treats
  that override as a replacement for the platform trust store. The managed
  proxy then rewrites child CA variables to its generated bundle, so the
  custom root or the ordinary platform roots can be lost. The proxy's
  upstream TLS connector must trust the same roots or private and
  corporate upstream certificates still fail after interception.
  
  ## What
  
  - load platform-native roots without consulting inherited CA override
  variables
  - append certificates from the existing curated startup CA file
  variables and `SSL_CERT_DIR`
  - share those platform and startup roots with the MITM upstream rustls
  connector
  - exclude the Codex managed MITM CA from upstream trust
  - normalize OpenSSL `TRUSTED CERTIFICATE` blocks while dropping trailing
  trust metadata
  - skip an inherited current Codex-managed bundle so nested launches do
  not duplicate it
  - append the Codex managed MITM CA to the child-facing bundle
  - copy certificate material only, so a private key or unrelated text
  colocated in a startup file is never exposed through the public bundle
  
  This is intentionally limited to CA paths present when Codex starts. It
  does not parse inline shell assignments or add per-command bundle
  materialization.
  
  This changes only `codex-network-proxy` and dependency metadata; it does
  not touch `codex-core` or sandbox orchestration.
  
  ## Validation
  
  - `just test -p codex-network-proxy`
  - includes an end-to-end upstream TLS test using a server trusted only
  by the startup custom CA
  - `just fix -p codex-network-proxy`
  - `just bazel-lock-check`
