## Business Logic Examples

### Batch Scaling Algorithm
```python
async def scale_recipe(recipe_id: UUID, target_yield: float, target_unit: str) -> ScaledRecipe:
    """
    Scale recipe ingredients to produce target yield.
    """
    # Get recipe and ingredients
    recipe = await get_recipe(recipe_id)
    ingredients = await get_recipe_ingredients(recipe_id)

    # Calculate scaling factor
    scaling_factor = target_yield / recipe.yield_quantity

    # Scale each ingredient
    scaled_ingredients = []
    for ingredient in ingredients:
        scaled_quantity = ingredient.quantity * scaling_factor

        # Round to practical values (e.g., 0.5g increments)
        scaled_quantity = round_to_practical_value(scaled_quantity, ingredient.unit)

        scaled_ingredients.append({
            "ingredient_id": ingredient.ingredient_id,
            "ingredient_name": ingredient.ingredient_name,
            "original_quantity": ingredient.quantity,
            "scaled_quantity": scaled_quantity,
            "unit": ingredient.unit,
            "preparation_notes": ingredient.preparation_notes
        })

    # Store scaling history
    await store_scaling_history(recipe_id, recipe.yield_quantity, target_yield, scaling_factor)

    return ScaledRecipe(
        recipe_id=recipe_id,
        recipe_name=recipe.recipe_name,
        original_yield=recipe.yield_quantity,
        target_yield=target_yield,
        scaling_factor=scaling_factor,
        scaled_ingredients=scaled_ingredients
    )
```

### Real-Time Cost Calculation
```python
async def calculate_recipe_cost(recipe_id: UUID) -> RecipeCost:
    """
    Calculate current recipe cost based on live ingredient prices.
    """
    # Get recipe ingredients

            "total_cost": ingredient_cost,
            "percentage_of_total": 0  # Calculated after loop
        })

    # Calculate percentages
    for item in cost_breakdown:
        item["percentage_of_total"] = (item["total_cost"] / total_cost) * 100

    # Get recipe yield
    recipe = await get_recipe(recipe_id)
    cost_per_unit = total_cost / recipe.yield_quantity

    # Get selling price if available
    selling_price = await get_product_selling_price(recipe.product_id)
    profit_margin = None
    if selling_price:
        profit_margin = ((selling_price - cost_per_unit) / selling_price) * 100

    # Store cost calculation
    cost_record = await store_recipe_cost(
        recipe_id=recipe_id,
        total_cost=total_cost,
        cost_per_unit=cost_per_unit,
        cost_breakdown=cost_breakdown,
        selling_price=selling_price,
        profit_margin=profit_margin
    )

    return cost_record
```

- XSS protection on recipe instructions
- Recipe versioning (prevent accidental overwrites)

### Audit Logging
```python
# Log all recipe modifications
logger.info(
    "recipe_updated",
    recipe_id=recipe.id,
    tenant_id=recipe.tenant_id,
    updated_by=current_user.id,
    changes=changes_dict,
    timestamp=datetime.utcnow()
)
```

## Competitive Advantages

### 1. Real-Time Cost Tracking
Unlike static recipe books, costs update automatically when ingredient prices change, enabling immediate pricing decisions.

### 2. Intelligent Scaling
Advanced scaling algorithm with practical rounding ensures recipes work in real-world production scenarios, not just mathematically.

### 3. Cross-Service Intelligence
Recipe data flows seamlessly to production, inventory, and procurement—no manual data entry or synchronization.

### 4. EU Compliance Built-In
Nutritional facts and allergen tracking meet EU food labeling regulations (EU FIC 1169/2011), avoiding costly fines.

### 5. Cost Breakdown Analysis
See exactly which ingredients drive costs, enabling targeted negotiations with suppliers or ingredient substitutions.

### 6. Recipe Versioning
Track recipe changes over time, enabling quality control and the ability to revert to previous versions.
