Pricing rules and resolution order

Kabaido prices every line through one resolution function, shared by the request pipeline, the quote builder and the API. The order is fixed so the same inputs always give the same price.

Resolution order for a product line

1. Start unit price = product.price_minor.
2. Apply the best special_prices match for the customer (most specific scope wins: product over category over schema; fixed price replaces, pct discounts).
3. Apply pricing_rules qty break for the achieved scope (highest min_qty less than or equal to qty; pct or fixed).
4. Never stack two rules of the same scope; specials and qty breaks do stack (special first, then qty break) unless the special is fixed_price (then qty breaks skip).

Configured and service lines

For configured and service lines, the engine output is the base. Special prices scoped to the configurator or service apply as a percentage only.

How priced provenance

The function returns the resolved unit price together with the list of applied steps, each with its kind, name and delta. That list is what powers the how priced popover on every quote line.
