failure.mapping_kind

Mapped failure's kind does not fit its condition.

Area 4, Failures; not declinable; the next step is usually the agent's.

example
type Quantity = Int {    min: 1    max: 1000}type QuantityRefused = Failure {    kind: FailureKind.rejected}function doubled(quantity: Quantity) fails QuantityRefused -> Quantity {    var result: Quantity = attempt Quantity(quantity * 2) {        max: QuantityRefused    }    return result}
