Boundary cases
items that do not fit neatly into any category and expose weaknesses in classification systems, serving as diagnostic signals rather than exceptions to be ignored
Why This Is a Definition
This definition names 'boundary cases,' establishes their genus as 'items,' and specifies their differentia as 'not fitting neatly into any category' and 'exposing weaknesses in classification systems.' It distinguishes boundary cases from exceptions by defining their function as 'diagnostic signals' rather than 'exceptions to be ignored,' and precisely defines their role in revealing system weaknesses.
