• Stabilize app list update ordering test (#14052)

  ## Summary
  - make
  `list_apps_waits_for_accessible_data_before_emitting_directory_updates`
  accept the two valid notification paths the server can emit
  - keep rejecting the real bug this test is meant to catch: a
  directory-only `app/list/updated` notification before accessible app
  data is available
  
  ## Why this fixes the flake
  The old test used a fixed `150ms` silence window and assumed the first
  notification after that window had to be the fully merged final update.
  In CI, scheduling occasionally lets accessible app data arrive before
  directory data, so the first valid notification can be an
  accessible-only interim update. That made the test fail even though the
  server behavior was correct.
  
  This change makes the test deterministic by reading notifications until
  the final merged payload arrives. Any interim update is only accepted if
  it contains accessible apps only; if the server ever emits inaccessible
  directory data before accessible data is ready, the test still fails
  immediately.
  
  ## Change type
  - test-only; no production app-list logic changes

• Add request permissions tool (#13092)

  Adds a built-in `request_permissions` tool and wires it through the
  Codex core, protocol, and app-server layers so a running turn can ask
  the client for additional permissions instead of relying on a static
  session policy.
  
  The new flow emits a `RequestPermissions` event from core, tracks the
  pending request by call ID, forwards it through app-server v2 as an
  `item/permissions/requestApproval` request, and resumes the tool call
  once the client returns an approved subset of the requested permission
  profile.

• fix(ci): restore guardian coverage and bazel unit tests (#13912)

  ## Summary
  - restore the guardian review request snapshot test and its tracked
  snapshot after it was dropped from `main`
  - make Bazel Rust unit-test wrappers resolve runfiles correctly on
  manifest-only platforms like macOS and point Insta at the real workspace
  root
  - harden the shell-escalation socket-closure assertion so the musl Bazel
  test no longer depends on fd reuse behavior
  
  ## Verification
  - cargo test -p codex-core
  guardian_review_request_layout_matches_model_visible_request_snapshot
  - cargo test -p codex-shell-escalation
  - bazel test //codex-rs/exec:exec-unit-tests
  //codex-rs/shell-escalation:shell-escalation-unit-tests
  
  Supersedes #13894.

• app-server: require absolute cwd for windowsSandbox/setupStart (#13833)

  ## Summary
  - require windowsSandbox/setupStart.cwd to be an AbsolutePathBuf
  - reject relative cwd values at request parsing instead of normalizing
  them later in the setup flow
  - add RPC-layer coverage for relative cwd rejection and update the
  checked-in protocol schemas/docs
  
  ## Why
  windowsSandbox/setupStart was carrying the client-provided cwd as a raw
  PathBuf for command_cwd while config derivation normalized the same
  value into an absolute policy_cwd.
  
  That left room for relative-path ambiguity in the setup path, especially
  for inputs like cwd: "repo". Making the RPC accept only absolute paths
  removes that split entirely: the handler now receives one
  already-validated absolute path and uses it for both config derivation
  and setup.
  
  This keeps the trust model unchanged. Trusted clients could already
  choose the session cwd; this change is only about making the setup RPC
  reject relative paths so command_cwd and policy_cwd cannot diverge.
  
  ## Testing
  - cargo test -p codex-app-server windows_sandbox_setup (run locally by
  user)
  - cargo test -p codex-app-server-protocol windows_sandbox (run locally
  by user)

• fix(app-server): fix turn_start_shell_zsh_fork_executes_command_v2 flake (#13770)

  This fixes a flaky `turn_start_shell_zsh_fork_executes_command_v2` test.
  
  The interrupt path can race with the follow-up `/responses` request that
  reports the aborted tool call, so the test now allows that extra no-op
  response instead of assuming there will only ever be one request. The
  assertions still stay focused on the behavior the test actually cares
  about: starting the zsh-forked command correctly.
  
  Testing:
  - `just fmt`
  - `cargo test -p codex-app-server --test all
  suite::v2::turn_start_zsh_fork::turn_start_shell_zsh_fork_executes_command_v2

• check app auth in plugin/install (#13685)

  #### What
  on `plugin/install`, check if installed apps are already authed on
  chatgpt, and return list of all apps that are not. clients can use this
  list to trigger auth workflows as needed.
  
  checks are best effort based on `codex_apps` loading, much like
  `app/list`.
  
  #### Tests
  Added integration tests, tested locally.

• add @plugin mentions (#13510)

  ## Note-- added plugin mentions via @, but that conflicts with file
  mentions
  
  depends and builds upon #13433.
  
  - introduces explicit `@plugin` mentions. this injects the plugin's mcp
  servers, app names, and skill name format into turn context as a dev
  message.
  - we do not yet have UI for these mentions, so we currently parse raw
  text (as opposed to skills and apps which have UI chips, autocomplete,
  etc.) this depends on a `plugins/list` app-server endpoint we can feed
  the UI with, which is upcoming
  - also annotate mcp and app tool descriptions with the plugin(s) they
  come from. this gives the model a first class way of understanding what
  tools come from which plugins, which will help implicit invocation.
  
  ### Tests
  Added and updated tests, unit and integration. Also confirmed locally a
  raw `@plugin` injects the dev message, and the model knows about its
  apps, mcps, and skills.

• feat(app-server): support mcp elicitations in v2 api (#13425)

  This adds a first-class server request for MCP server elicitations:
  `mcpServer/elicitation/request`.
  
  Until now, MCP elicitation requests only showed up as a raw
  `codex/event/elicitation_request` event from core. That made it hard for
  v2 clients to handle elicitations using the same request/response flow
  as other server-driven interactions (like shell and `apply_patch`
  tools).
  
  This also updates the underlying MCP elicitation request handling in
  core to pass through the full MCP request (including URL and form data)
  so we can expose it properly in app-server.
  
  ### Why not `item/mcpToolCall/elicitationRequest`?
  This is because MCP elicitations are related to MCP servers first, and
  only optionally to a specific MCP tool call.
  
  In the MCP protocol, elicitation is a server-to-client capability: the
  server sends `elicitation/create`, and the client replies with an
  elicitation result. RMCP models it that way as well.
  
  In practice an elicitation is often triggered by an MCP tool call, but
  not always.
  
  ### What changed
  - add `mcpServer/elicitation/request` to the v2 app-server API
  - translate core `codex/event/elicitation_request` events into the new
  v2 server request
  - map client responses back into `Op::ResolveElicitation` so the MCP
  server can continue
  - update app-server docs and generated protocol schema
  - add an end-to-end app-server test that covers the full round trip
  through a real RMCP elicitation flow
  - The new test exercises a realistic case where an MCP tool call
  triggers an elicitation, the app-server emits
  mcpServer/elicitation/request, the client accepts it, and the tool call
  resumes and completes successfully.
  
  ### app-server API flow
  - Client starts a thread with `thread/start`.
  - Client starts a turn with `turn/start`.
  - App-server sends `item/started` for the `mcpToolCall`.
  - While that tool call is in progress, app-server sends
  `mcpServer/elicitation/request`.
  - Client responds to that request with `{ action: "accept" | "decline" |
  "cancel" }`.
  - App-server sends `serverRequest/resolved`.
  - App-server sends `item/completed` for the mcpToolCall.
  - App-server sends `turn/completed`.
  - If the turn is interrupted while the elicitation is pending,
  app-server still sends `serverRequest/resolved` before the turn
  finishes.

• allow apps to specify cwd for sandbox setup. (#13484)

  The electron app doesn't start up the app-server in a particular
  workspace directory.
  So sandbox setup happens in the app-installed directory instead of the
  project workspace.
  
  This allows the app do specify the workspace cwd so that the sandbox
  setup actually sets up the ACLs instead of exiting fast and then having
  the first shell command be slow.

  This adds a first-class app-server v2 `skills/changed` notification for

  legacy `codex/event/*` stream, which we want to remove soon.

• Add under-development original-resolution view_image support (#13050)

  ## Summary
  
  Add original-resolution support for `view_image` behind the
  under-development `view_image_original_resolution` feature flag.
  
  When the flag is enabled and the target model is `gpt-5.3-codex` or
  newer, `view_image` now preserves original PNG/JPEG/WebP bytes and sends
  `detail: "original"` to the Responses API instead of using the legacy
  resize/compress path.
  
  ## What changed
  
  - Added `view_image_original_resolution` as an under-development feature
  flag.
  - Added `ImageDetail` to the protocol models and support for serializing
  `detail: "original"` on tool-returned images.
  - Added `PromptImageMode::Original` to `codex-utils-image`.
    - Preserves original PNG/JPEG/WebP bytes.
    - Keeps legacy behavior for the resize path.
  - Updated `view_image` to:
  - use the shared `local_image_content_items_with_label_number(...)`
  helper in both code paths
    - select original-resolution mode only when:
      - the feature flag is enabled, and
      - the model slug parses as `gpt-5.3-codex` or newer
  - Kept local user image attachments on the existing resize path; this
  change is specific to `view_image`.
  - Updated history/image accounting so only `detail: "original"` images
  use the docs-based GPT-5 image cost calculation; legacy images still use
  the old fixed estimate.
  - Added JS REPL guidance, gated on the same feature flag, to prefer JPEG
  at 85% quality unless lossless is required, while still allowing other
  formats when explicitly requested.
  - Updated tests and helper code that construct
  `FunctionCallOutputContentItem::InputImage` to carry the new `detail`
  field.
  
  ## Behavior
  
  ### Feature off
  - `view_image` keeps the existing resize/re-encode behavior.
  - History estimation keeps the existing fixed-cost heuristic.
  
  ### Feature on + `gpt-5.3-codex+`
  - `view_image` sends original-resolution images with `detail:
  "original"`.
  - PNG/JPEG/WebP source bytes are preserved when possible.
  - History estimation uses the GPT-5 docs-based image-cost calculation
  for those `detail: "original"` images.

• Add thread metadata update endpoint to app server (#13280)

  ## Summary
  - add the v2 `thread/metadata/update` API, including
  protocol/schema/TypeScript exports and app-server docs
  - patch stored thread `gitInfo` in sqlite without resuming the thread,
  with validation plus support for explicit `null` clears
  - repair missing sqlite thread rows from rollout data before patching,
  and make those repairs safe by inserting only when absent and updating
  only git columns so newer metadata is not clobbered
  - keep sqlite authoritative for mutable thread git metadata by
  preserving existing sqlite git fields during reconcile/backfill and only
  using rollout `SessionMeta` git fields to fill gaps
  - add regression coverage for the endpoint, repair paths, concurrent
  sqlite writes, clearing git fields, and rollout/backfill reconciliation
  - fix the login server shutdown race so cancelling before the waiter
  starts still terminates `block_until_done()` correctly

• chore(app-server): delete v1 RPC methods and notifications (#13375)

  ## Summary
  This removes the old app-server v1 methods and notifications we no
  longer need, while keeping the small set the main codex app client still
  depends on for now.
  
  The remaining legacy surface is:
  - `initialize`
  - `getConversationSummary`
  - `getAuthStatus`
  - `gitDiffToRemote`
  - `fuzzyFileSearch`
  - `fuzzyFileSearch/sessionStart`
  - `fuzzyFileSearch/sessionUpdate`
  - `fuzzyFileSearch/sessionStop`
  
  And the raw `codex/event/*` notifications emitted from core. These
  notifications will be removed in a followup PR.
  
  ## What changed
  - removed deprecated v1 request variants from the protocol and
  app-server dispatcher
  - removed deprecated typed notifications: `authStatusChange`,
  `loginChatGptComplete`, and `sessionConfigured`
  - updated the app-server test client to use v2 flows instead of deleted
  v1 flows
  - deleted legacy-only app-server test suites and added focused coverage
  for `getConversationSummary`
  - regenerated app-server schema fixtures and updated the MCP interface
  docs to match the remaining compatibility surface
  
  ## Testing
  - `just write-app-server-schema`
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-app-server`

• app-server: Silence thread status changes caused by thread being created (#13079)

  Currently we emit `thread/status/changed` with `Idle` status right
  before sending `thread/started` event (which also has `Idle` status in
  it).
  It feels that there is no point in that as client has no way to know
  prior state of the thread as it didn't exist yet, so silence these kinds
  of notifications.

• fix(app-server): emit turn/started only when turn actually starts (#13261)

  This is a follow-up for https://github.com/openai/codex/pull/13047
  
  ## Why
  We had a race where `turn/started` could be observed before the thread
  had actually transitioned to `Active`. This was because we eagerly
  emitted `turn/started` in the request handler for `turn/start` (and
  `review/start`).
  
  That was showing up as flaky `thread/resume` tests, but the real issue
  was broader: a client could see `turn/started` and still get back an
  idle thread immediately afterward.
  
  The first idea was to eagerly call
  `thread_watch_manager.note_turn_started(...)` from the `turn/start`
  request path. That turns out to be unsafe, because
  `submit(Op::UserInput)` only queues work. If a turn starts and completes
  quickly, request-path bookkeeping can race with the real lifecycle
  events and leave stale running state behind.
  
  **The real fix** is to move `turn/started` to emit only after the turn
  _actually_ starts, so we do that by waiting for the
  `EventMsg::TurnStarted` notification emitted by codex core. We do this
  for both `turn/start` and `review/start`.
  
  I also verified this change is safe for our first-party codex apps -
  they don't have any assumptions that `turn/started` is emitted before
  the RPC response to `turn/start` (which is correct anyway).
  
  I also removed `single_client_mode` since it isn't really necessary now.
  
  ## Testing
  - `cargo test -p codex-app-server thread_resume -- --nocapture`
  - `cargo test -p codex-app-server
  'suite::v2::turn_start::turn_start_emits_notifications_and_accepts_model_override'

• feat(app-server): add tracing to all app-server APIs (#13285)

  ### Overview
  This PR adds the first piece of tracing for app-server JSON-RPC
  requests.
  
  There are two main changes:
  - JSON-RPC requests can now take an optional W3C trace context at the
  top level via a `trace` field (`traceparent` / `tracestate`).
  - app-server now creates a dedicated request span for every inbound
  JSON-RPC request in `MessageProcessor`, and uses the request-level trace
  context as the parent when present.
  
  For compatibility with existing flows, app-server still falls back to
  the TRACEPARENT env var when there is no request-level traceparent.
  
  This PR is intentionally scoped to the app-server boundary. In a
  followup, we'll actually propagate trace context through the async
  handoff into core execution spans like run_turn, which will make
  app-server traces much more useful.
  
  ### Spans
  A few details on the app-server span shape:
  - each inbound request gets its own server span
  - span/resource names are based on the JSON-RPC method (`initialize`,
  `thread/start`, `turn/start`, etc.)
  - spans record transport (stdio vs websocket), request id, connection
  id, and client name/version when available
  - `initialize` stores client metadata in session state so later requests
  on the same connection can reuse it

  - increase `DEFAULT_READ_TIMEOUT` in `codex_message_processor_flow` from
  20s to 45s
  - keep test behavior the same while avoiding platform timing flakes
  
  ## Why
  Windows ARM64 CI showed these tests taking about 24s before
  `task_complete`, which could fail early and produce wiremock
  request-count mismatches.
  
  ## Testing
  - just fmt
  - cargo test -p codex-app-server codex_message_processor_flow --
  --nocapture

• [codex] include plan type in account updates (#13181)

  This change fixes a Codex app account-state sync bug where clients could
  know the user was signed in but still miss the ChatGPT subscription
  tier, which could lead to incorrect upgrade messaging for paid users.
  
  The root cause was that `account/updated` only carried `authMode` while
  plan information was available separately via `account/read` and
  rate-limit snapshots, so this update adds `planType` to
  `account/updated`, populates it consistently across login and refresh
  paths.

• Handle missing plan info for ChatGPT accounts (#13072)

  Addresses https://github.com/openai/codex/issues/13007 and
  https://github.com/openai/codex/issues/12170
  
  There are situations where the ChatGPT auth backend might return a JWT
  that contains no plan information. Most code paths already handle this
  case well, but the internal implementation of the "account/read" app
  server call was failing in this case (returning an error rather than
  properly returning None for the plan).
  
  This resulted in a situation where users needed to log in every time the
  extension or app started even if they successfully logged in the last
  time.
  
  Summary
  - allow ChatGPT-authenticated accounts to fall back to
  `AccountPlanType::Unknown` when the token omits the plan claim
  - add regression coverage in `app-server/tests/suite/v2/account.rs` to
  confirm `account/read` returns `plan_type: Unknown` when the claim is
  absent
  - ensure the Rust auth helpers and fixtures treat missing plan claims as
  Optional and default to `Unknown`

• [apps] Stablize app list updated event. (#13067)

  Stablize app list updated event so that we only send 2 updates: 1 when
  installed apps become available, one when all directory apps are
  available. Previously it also updates when directory apps become
  available before installed apps, which cuts off installed apps.

• app-server: Replay pending item requests on thread/resume (#12560)

  Replay pending client requests after `thread/resume` and emit resolved
  notifications when those requests clear so approval/input UI state stays
  in sync after reconnects and across subscribed clients.
  
  Affected RPCs:
  - `item/commandExecution/requestApproval`
  - `item/fileChange/requestApproval`
  - `item/tool/requestUserInput`
  
  Motivation:
  - Resumed clients need to see pending approval/input requests that were
  already outstanding before the reconnect.
  - Clients also need an explicit signal when a pending request resolves
  or is cleared so stale UI can be removed on turn start, completion, or
  interruption.
  
  Implementation notes:
  - Use pending client requests from `OutgoingMessageSender` in order to
  replay them after `thread/resume` attaches the connection, using
  original request ids.
  - Emit `serverRequest/resolved` when pending requests are answered
  or cleared by lifecycle cleanup.
  - Update the app-server protocol schema, generated TypeScript bindings,
  and README docs for the replay/resolution flow.
  
  High-level test plan:
  - Added automated coverage for replaying pending command execution and
  file change approval requests on `thread/resume`.
  - Added automated coverage for resolved notifications in command
  approval, file change approval, request_user_input, turn start, and turn
  interrupt flows.
  - Verified schema/docs updates in the relevant protocol and app-server
  tests.
  
  Manual testing:
  - Tested reconnect/resume with multiple connections.
  - Confirmed state stayed in sync between connections.

• app-server: deflake running thread resume tests (#13047)

  ## Why
  
  CI has been intermittently failing in
  `suite::v2::thread_resume::thread_resume_rejoins_running_thread_even_with_override_mismatch`
  because these running-thread resume tests treated `turn/started` as
  proof that the thread was already active.
  
  That signal is too early for this path. `turn/started` is emitted
  optimistically from
  [`turn_start`](https://github.com/openai/codex/blob/1103d0037e3bff798ed07b9e003b0cd360756ced/codex-rs/app-server/src/codex_message_processor.rs#L5757-L5767).
  In `single_client_mode`, the listener skips `current_turn_history`
  tracking in
  [`codex_message_processor.rs`](https://github.com/openai/codex/blob/1103d0037e3bff798ed07b9e003b0cd360756ced/codex-rs/app-server/src/codex_message_processor.rs#L6461-L6465),
  so running-thread resume still depends on `ThreadWatchManager` observing
  the core `TurnStarted` event in
  [`bespoke_event_handling.rs`](https://github.com/openai/codex/blob/1103d0037e3bff798ed07b9e003b0cd360756ced/codex-rs/app-server/src/bespoke_event_handling.rs#L152-L156).
  If `thread/resume` lands in that window, the thread can still look
  `Idle` and the assertion flakes.
  
  ## What
  
  - Add a helper in `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
  that waits for `thread/status/changed` to report `Active` for the target
  thread.
  - Use that public v2 notification as the synchronization barrier in the
  four running-thread resume tests instead of relying on `turn/started`.
  
  ## Follow-up
  
  This PR keeps the fix at the test layer so we can remove the flake
  without changing server behavior. A broader runtime fix should still be
  considered separately, for example:
  
  - make `turn/start` eagerly transition the thread to `Active` so
  `turn/started` and `thread/status/changed` are coherent
  - or revisit the `single_client_mode` guard that skips current-turn
  tracking for running-thread resume
  
  ## Testing
  
  - `cargo test -p codex-app-server thread_resume -- --nocapture`
  - `for i in $(seq 1 10); do cargo test -p codex-app-server
  'suite::v2::thread_resume::thread_resume_rejoins_running_thread_even_with_override_mismatch'
  -- --exact --nocapture; done`

• fix: more stable notify script (#13011)

• notify: include client in legacy hook payload (#12968)

  ## Why
  
  The `notify` hook payload did not identify which Codex client started
  the turn. That meant downstream notification hooks could not distinguish
  between completions coming from the TUI and completions coming from
  app-server clients such as VS Code or Xcode. Now that the Codex App
  provides its own desktop notifications, it would be nice to be able to
  filter those out.
  
  This change adds that context without changing the existing payload
  shape for callers that do not know the client name, and keeps the new
  end-to-end test cross-platform.
  
  ## What changed
  
  - added an optional top-level `client` field to the legacy `notify` JSON
  payload
  - threaded that value through `core` and `hooks`; the internal session
  and turn state now carries it as `app_server_client_name`
  - set the field to `codex-tui` for TUI turns
  - captured `initialize.clientInfo.name` in the app server and applied it
  to subsequent turns before dispatching hooks
  - replaced the notify integration test hook with a `python3` script so
  the test does not rely on Unix shell permissions or `bash`
  - documented the new field in `docs/config.md`
  
  ## Testing
  
  - `cargo test -p codex-hooks`
  - `cargo test -p codex-tui`
  - `cargo test -p codex-app-server
  suite::v2::initialize::turn_start_notify_payload_includes_initialize_client_name
  -- --exact --nocapture`
  - `cargo test -p codex-core` (`src/lib.rs` passed; `core/tests/all.rs`
  still has unrelated existing failures in this environment)
  
  ## Docs
  
  The public config reference on `developers.openai.com/codex` should
  mention that the legacy `notify` payload may include a top-level
  `client` field. The TUI reports `codex-tui`, and the app server reports
  `initialize.clientInfo.name` when it is available.

• feat: add local date/timezone to turn environment context (#12947)

  ## Summary
  
  This PR includes the session's local date and timezone in the
  model-visible environment context and persists that data in
  `TurnContextItem`.
  
    ## What changed
  - captures the current local date and IANA timezone when building a turn
  context, with a UTC fallback if the timezone lookup fails
  - includes current_date and timezone in the serialized
  <environment_context> payload
  - stores those fields on TurnContextItem so they survive rollout/history
  handling, subagent review threads, and resume flows
  - treats date/timezone changes as environment updates, so prompt caching
  and context refresh logic do not silently reuse stale time context
  - updates tests to validate the new environment fields without depending
  on a single hardcoded environment-context string
  
  ## test
  
  built a local build and saw it in the rollout file:
  ```
  {"timestamp":"2026-02-26T21:39:50.737Z","type":"response_item","payload":{"type":"message","role":"user","content":[{"type":"input_text","text":"<environment_context>\n  <shell>zsh</shell>\n  <current_date>2026-02-26</current_date>\n  <timezone>America/Los_Angeles</timezone>\n</environment_context>"}]}}

• core: bundle settings diff updates into one dev/user envelope (#12417)

  ## Summary
  - bundle contextual prompt injection into at most one developer message
  plus one contextual user message in both:
    - per-turn settings updates
    - initial context insertion
  - preserve `<model_switch>` across compaction by rebuilding it through
  canonical initial-context injection, instead of relying on
  strip/reattach hacks
  - centralize contextual user fragment detection in one shared definition
  table and reuse it for parsing/compaction logic
  - keep `AGENTS.md` in its natural serialized format:
    - `# AGENTS.md instructions for {dirname}`
    - `<INSTRUCTIONS>...</INSTRUCTIONS>`
  - simplify related tests/helpers and accept the expected snapshot/layout
  updates from bundled multi-part messages
  
  ## Why
  The goal is to converge toward a simpler, more intentional prompt shape
  where contextual updates are consistently represented as one developer
  envelope plus one contextual user envelope, while keeping parsing and
  compaction behavior aligned with that representation.
  
  ## Notable details
  - the temporary `SettingsUpdateEnvelope` wrapper was removed; these
  paths now return `Vec<ResponseItem>` directly
  - local/remote compaction no longer rely on model-switch strip/restore
  helpers
  - contextual user detection is now driven by shared fragment definitions
  instead of ad hoc matcher assembly
  - AGENTS/user instructions are still the same logical context; only the
  synthetic `<user_instructions>` wrapper was replaced by the natural
  AGENTS text format
  
  ## Testing
  - `just fmt`
  - `cargo test -p codex-app-server

  ## Notes
  - I also ran several targeted `compact`, `compact_remote`,
  `prompt_caching`, `model_visible_layout`, and `event_mapping` tests
  while iterating on prompt-shape changes.
  - I have not claimed a clean full-workspace `cargo test` from this
  environment because local sandbox/resource conditions have previously
  produced unrelated failures in large workspace runs.
