After mapping callback

[mabar]

Description

It is easier and more type-safe to check dependencies between properties after object was fully mapped

    public function validate(): void {
        if (
            $this->status === Status::PAID && $this->paidAt === null
            || $this->status === Status::UNPAID && $this->paidAt !== null
        ) {
           throw ValueDoesNotMatch::createFromString('Payment date can only be set if and only if the status is `paid`.', Value::none());
        }
    }
