    "A record is a Purchase with status APPROVED, transactionType EXPENSE, a non-null receiptId, and a purchaseDate in the stated window.",
    "The purchase-date window is applied to the saved timestamp without a user-local timezone conversion.",
    "All selected receipt links match distinct Receipt objects owned by the same user as the expense record.",
    "A product row is a PurchaseItem with itemType product; separate discount rows are excluded from the row count.",
    "A category is a standard system root reached through Category.parentCode from a product row's saved categoryCode, using the hierarchy at extraction.",
    "Category mapping excludes user-created custom categories; a record with only custom or unclassified rows has no mapped standard category.",
    "The category-breadth chart includes records with at least one mapped standard category and counts distinct roots per record.",
    "The grocery chart includes records with a groceries root and splits them by the presence of a householdPersonal root.",
    "The product-row chart includes all selected records, including records with zero saved product rows.",
    "Users are distinct saved user IDs, not verified households or unique people. A user can appear in several chart groups."

    "This is a descriptive sample from Yomio, produced by the app's team; users chose which records to save.",
    "The 152 most active users contributed 9,909 of the 15,179 records, so record-level results weight frequent contributors more heavily.",
    "Category labels and product rows were not checked against receipt images, and approval status does not establish a manual quality check.",
    "A product row can have a quantity above one; its count does not establish units bought or verified distinct products.",
    "These figures do not estimate population spending, category spending amounts, product popularity, OCR accuracy, savings, or inflation."
