std/pricing (§3.7, M2): catalogue lines → bands → formula → bucket → line. A catalogue line carries ordered bands of formula text; a band that holds (when) takes a slice of the quantity (take, default all that is left) and prices it (price, reading the slice as the root quantity); each priced slice is one line in the catalogue line's bucket. Payroll overtime bands, allowance families, CRM price breaks and commissions are all this shape.

PricedLine type

type PricedLine<C = Ctx> = {
    readonly code: string;
    readonly label: string;
    readonly bucket: string;

    readonly quantity: Decimal | null;
    readonly amount: Amount<C>;
};
