What the demonstration suggests
A short column label can become a repeated classification instruction, turning free-text rows into categories such as follow-up urgency.
Where the value sits
The pattern is useful when the output choices are explicit and a person can scan or correct a whole column. The same-author follow-up links the public experiment repository.
