### 9.2 Rate Types

For the matched zone, return all active shipping rates (`is_active = 1`). Calculate cost for each:

#### Flat rate

Config structure: `{"amount": 500}`

- Cost = fixed amount regardless of cart contents.

#### Weight-based rate

Config structure: `{"ranges": [{"min_g": 0, "max_g": 1000, "amount": 500}, {"min_g": 1001, "max_g": 5000, "amount": 1000}]}`

```
PROCEDURE calculateWeightRate(config, cart):
    totalWeight = 0
    FOR EACH line IN cart.lines:
        IF line.variant.requires_shipping = true:
            totalWeight += line.variant.weight_g * line.quantity

    FOR EACH range IN config.ranges:
        IF range.min_g <= totalWeight AND totalWeight <= range.max_g:
            RETURN range.amount

    RETURN null  // Rate not available for this weight
```

#### Price-based rate

Config structure: `{"ranges": [{"min_amount": 0, "max_amount": 5000, "amount": 500}, {"min_amount": 5001, "amount": 0}]}`

```
PROCEDURE calculatePriceRate(config, cartSubtotal):
    FOR EACH range IN config.ranges:
        IF range.min_amount <= cartSubtotal:
            IF range.max_amount IS NOT SET OR cartSubtotal <= range.max_amount:
                RETURN range.amount

    RETURN null  // Rate not available for this subtotal
```

A range without `max_amount` matches all subtotals above `min_amount` (useful for "free shipping over X" rules).

#### Carrier-calculated rate (stub)

Config structure: `{"carrier": "ups", "service": "ground"}`

- Placeholder for future carrier API integration.
- Returns a hardcoded rate or error until implemented.

### 9.3 Requires Shipping Check

- If no line in the cart has `requires_shipping = true` on its variant, the shipping step is skipped entirely.
- shipping_amount = 0 in the pricing result.
- The checkout transitions directly past `shipping_selected` (set status to `shipping_selected` with shipping_method_id = null).

**Mixed carts** (some physical, some digital):
- Shipping is calculated only for physical items' weight.
- Digital items are excluded from weight calculations.

### 9.4 Free Shipping Discount Override

If a validated discount has `value_type = 'free_shipping'`:
- Override the calculated shipping amount to 0.
- The shipping method is still selected (for fulfillment routing), but the customer is not charged.

#### Flat rate

Config structure: `{"amount": 500}`

- Cost = fixed amount regardless of cart contents.

#### Weight-based rate

Config structure: `{"ranges": [{"min_g": 0, "max_g": 1000, "amount": 500}, {"min_g": 1001, "max_g": 5000, "amount": 1000}]}`

```
PROCEDURE calculateWeightRate(config, cart):
    totalWeight = 0
    FOR EACH line IN cart.lines:
        IF line.variant.requires_shipping = true:
            totalWeight += line.variant.weight_g * line.quantity

    FOR EACH range IN config.ranges:
        IF range.min_g <= totalWeight AND totalWeight <= range.max_g:
            RETURN range.amount

    RETURN null  // Rate not available for this weight
```

#### Price-based rate

Config structure: `{"ranges": [{"min_amount": 0, "max_amount": 5000, "amount": 500}, {"min_amount": 5001, "amount": 0}]}`

```
PROCEDURE calculatePriceRate(config, cartSubtotal):
    FOR EACH range IN config.ranges:
        IF range.min_amount <= cartSubtotal:
            IF range.max_amount IS NOT SET OR cartSubtotal <= range.max_amount:
                RETURN range.amount

    RETURN null  // Rate not available for this subtotal
```

A range without `max_amount` matches all subtotals above `min_amount` (useful for "free shipping over X" rules).

#### Carrier-calculated rate (stub)

Config structure: `{"carrier": "ups", "service": "ground"}`

- Placeholder for future carrier API integration.
- Returns a hardcoded rate or error until implemented.

### 9.3 Requires Shipping Check

- If no line in the cart has `requires_shipping = true` on its variant, the shipping step is skipped entirely.
- shipping_amount = 0 in the pricing result.
- The checkout transitions directly past `shipping_selected` (set status to `shipping_selected` with shipping_method_id = null).

**Mixed carts** (some physical, some digital):
- Shipping is calculated only for physical items' weight.
- Digital items are excluded from weight calculations.

### 9.4 Free Shipping Discount Override

If a validated discount has `value_type = 'free_shipping'`:
- Override the calculated shipping amount to 0.
- The shipping method is still selected (for fulfillment routing), but the customer is not charged.
