    "description": "The same behavior as 13-if-else-append.json, expressed as a decision table so the condition is written once. The field and operator live in 'inputs', the threshold appears once in row 0, and the all-wildcard row 1 is the 'else' branch. With hitPolicy 'first' exactly one row applies. Trade-off vs. 13: no duplicated/negated condition to keep in sync, at the cost of being less obvious to a first-time reader.",
