    "Estimated from listed ingredient amounts and USDA nutrient profiles, divided by the stated number of servings. Not laboratory analysis or kitchen testing.",
    "The ingredient-sum method uses raw or cooked food profiles matching the ingredient state. Moisture gain/loss does not change the stated serving count. No general cooking/fermentation nutrient-retention factors are applied.",
    "Unless a discard/absorption blocker is listed, all measured pan fats and sauces are assumed consumed. Actual amounts left in pans, on utensils or during cooking can reduce intake. Optional additions are excluded when noted.",
    "Calories are kcal. Protein, total carbohydrate, total fat and total sugar are grams. Total carbohydrate includes fiber; these are not net carbs. No %DV or FDA-compliance claim.",
    "Null means unavailable, never zero. Sodium and fiber are omitted because retention, brands, rinsing and missing source rows make them less reliable here.",
    "100 g starter at 100% hydration modeled as 50 g water and 50 g flour, split 25 g bread flour /25 g whole-wheat flour per the linked starter recipe. All 15 g dusting flour counted; fermentation losses not modeled."
