Task Composer displays a backend fallback catalog when the selected Mac's model discovery times out or its connection closes. The fallback has no host-provided effort metadata. Existing discovery logs report a model count but do not identify the visible catalog's provider or source.

Add ios_task_model_result through the shared diagnostic log, iOS uploader, and Axiom ingress. Each visible catalog update records a fixed provider/source value, aggregate effort count, and a process-local correlation handle. Model IDs and command output remain private. Decode provider values by event kind so a successful Codex result cannot be mislabeled as a timeout.

This is an observability change; it does not repair the underlying Mac connection failure. Model discovery retry behavior remains covered by the existing catalog tests.

Validation:

  • 13 shared diagnostic presentation tests, including a regression observed failing before the fix
  • 13 iOS analytics reporter tests
  • 12 iOS model catalog tests
  • 20 web observability route tests
  • Web typecheck, complexity gate, and Swift conventions check

Build limitations: controller job 7d230a57d244b3fc5953233f for head cc4a7765760a74eb8074984e9e6213099dddc9f9 failed before compilation (393 ms in the build phase). The iOS submission was blocked before job creation by the shared backend disk floor (49 GiB free, 50 GiB required). Both were reported to the build-fleet journal. No simulator or iPhone verification is claimed.

📝 Walkthrough

Walkthrough

The change records task-model list results with provider, source, effort count, and optional correlation ID. It adds iOS analytics reporting and web observability parsing and span emission for these results.

Changes

Task model result observability

Layer / File(s) Summary
Define and record task-model results
Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticTaxonomy.swift, Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticLog.swift, Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticEventPresentation.swift, Packages/Shared/CMUXMobileCore/Tests/CMUXMobileCoreTests/DiagnosticEventPresentationTests.swift, Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite+AppDiagnostics.swift, Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite+TaskModels.swift
The diagnostic taxonomy adds result, provider, and source values. The shell counts efforts across unique model IDs and records results during refresh. Diagnostic event presentation maps result fields and does not interpret the provider as a failure.
Map results to iOS analytics
Packages/iOS/CmuxMobileAnalytics/Sources/CmuxMobileAnalytics/MobileNetworkOutcomeReporter.swift, Packages/iOS/CmuxMobileAnalytics/Tests/CmuxMobileAnalyticsTests/MobileNetworkOutcomeReporterTests.swift
The reporter maps result diagnostics to the ios_task_model_result event and its properties. A test checks the emitted values.
Validate and emit web observations
web/services/observability/mobileNetworkOutcome.ts, web/tests/mobile-network-observability-route.test.ts
The web parser validates task-model result events, and the emitter writes result spans. A route test checks acceptance and field normalization.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to cc4a7

Task-model diagnostics work through the mobile and web paths, but their new field labels appear untranslated. Localize those labels before merge or accept the limited presentation issue as follow-up.

Explanation

The PR adds user-facing diagnostic report/log text without localization. DiagnosticEventPresentation returns literal claude, codex, opencode, discovered, backend, augmented, and fallback values for Field.value, and it emits new provider, source, and effort_count field keys. These values flow through summary, AppLog, and DiagnosticReport.humanReadableExport, which are human-readable output paths. The touched Localizable.xcstrings has no matching provider, source, or effort-count entries. The web changes are telemetry ingestion and protocol tokens, not user-facing copy.

Resolution

Route the new diagnostic field labels and provider/source display values through DiagnosticLocalization.string (or an equivalent localized API). Add matching keys to Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/Resources/Localizable.xcstrings with translated values for every locale already present in that catalog (en, ja, de, fr, ar, es, zh-Hans, zh-Hant, and ko).

event-aware failure predicate so task-model list result events are excluded from
failure decoding before the provider branch in decodeB. Preserve failure
classification for other events, and add a regression test covering a task-model
provider raw value that overlaps a failure kind.

🟡 Minor · Localize the new diagnostic field labels. · DiagnosticEventPresentation.swift:521

Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticEventPresentation.swift:521
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Localize the new diagnostic field labels.

summary(_:) passes provider, source, and effort_count to label(for:). That function has no cases for these keys, so user-facing summaries display the raw keys, including effort_count, in every locale. Add localized labels in DiagnosticEventPresentation.swift and translated entries in the matching string catalogs for every supported locale. Keep the provider and source values as protocol identifiers.

As per path instructions: “Flag production changes that add or materially change user-facing Swift or web text unless it uses the appropriate localization API/source and is represented in every supported locale.”

Also applies to: 562-562, 628-628
