each item in a Category consists of a Name, a Description (which describes the item in a Category), and a number named Expiration which defaults to 3

and in the same rule, after the text “a Storyteller may add one entry, which must consist of a Name and Description” add the following text:

and the default value for Expiration

In the rule “Judging”, add the following step just before the last step in the Publishing atomic action:

* For the Category that is in the Current Elements, subtract 1 from the Expiration of each entry in that Category that was not contained in any Fragment in that Judging. If that entry’s Expiration is 0 after this operation, remove that entry from that Category.
