      "expected_output": "A source-grounded FinanceKit setup and query outline that covers managed entitlement eligibility, region/platform support, data availability, authorization, and transaction query details without treating amounts as signed values.",

        "States that `com.apple.developer.financekit` is a managed entitlement requested by the Account Holder for an organization-level Apple Developer account and approved per bundle ID.",
        "Mentions App Store Finance category and iPhone distribution in the U.S. or U.K. as entitlement eligibility constraints.",
        "Distinguishes U.S. Apple Card, Apple Cash, and Savings data from U.K. open-banking connected-account support and includes relevant iOS availability.",
        "Adds `NSFinancialDataUsageDescription` and checks `FinanceStore.isDataAvailable(.financialData)` before authorization or financial-data API calls.",
        "Uses `try await FinanceStore.shared.requestAuthorization()` or `authorizationStatus()` and handles `.authorized`, `.denied`, and `.notDetermined`.",
        "Builds a `TransactionQuery` with predicate, sort descriptors, limit, and offset, and calls `try await store.transactions(query:)`.",

      "prompt": "Review this import plan: use TransactionPicker for expense reports, store the selected Transaction IDs forever, then use those IDs later to keep syncing updates. If users want full-budgeting sync, ask for all accounts and fetch complete snapshots every launch.",
      "expected_output": "A correction-focused answer that keeps TransactionPicker as ephemeral selective access, uses FinanceKit authorization plus history tokens for persistent sync, handles deletions/token invalidation, and avoids over-querying.",
      "files": [],
      "assertions": [
        "Explains that `TransactionPicker` selected transactions are passed directly for immediate use and access is ephemeral, not persistent sync authorization.",
        "Recommends FinanceKit authorization and account selection for ongoing account, balance, and transaction access.",
        "Uses `transactionHistory(forAccountID:since:isMonitoring:)` with persisted `FinanceStore.HistoryToken` for resumable incremental sync.",
        "Saves every `changes.newToken` and applies inserted, updated, and deleted changes, including removing locally stored deleted data.",
        "Handles `FinanceError.historyTokenInvalid` by discarding the token and immediately resynchronizing the affected stream.",
        "Prefers `isMonitoring: false` for catch-up-only sync and avoids fetching complete snapshots every launch.",
        "Keeps the answer in FinanceKit/FinanceKitUI rather than drifting into PassKit payment processing or generic data-store architecture."

      "expected_output": "An iOS 26 background delivery plan that uses the current synchronous registration APIs, implements BackgroundDeliveryExtension entry points, shares data through App Groups, inherits app authorization, and routes unrelated widget UI/payment work to the right domains.",

        "States that FinanceKit background delivery is iOS/iPadOS 26+ and uses a Background Delivery Extension target.",
