Are there any errors in the specification?

Question

Preparation of terms of reference

It is necessary to find errors in the specification

When performing the operation of placing an order and paying for it in an online store, you must:
1. Analyze the product code
2. Analyze the age of the buyer, etc.
Precondition.
In the "References" section, reference 1 "Product codes prohibited for sale
to children" is filled out.
The online store has been improved in terms of the formation and payment of an order with products
prohibited for sale to children, and other improvements.
Main scenario. The buyer is a child, the product code is allowed.
1. The system generates an order and determines that the recipient of the order (buyer) is a child.
2. The system determines by the product code that the product code is not present in the directory 12.
Perhaps in this case, the operation of placing an order or paying for orders is carried out.
Alternative Scenario 1. The customer is a child, product code is not allowed.
1. The system forms an order, determines that the recipient of the order (buyer) is a child.
2. The system determines by the product code that the product code is present in directory 1, then the
operation of placing an order or paying for orders is not carried out.
Alternative scenario 2. Other situations.
1.Ostalnye cases of the system remain the same (in the future I will specify exactly).
