Defined in: src/batteries/orchestration/predicates.ts:13

The closed set of comparison operators a structured predicate leaf may name.

truthy and exists take no value; every other operator requires one. The set is CLOSED — parseStructuredPredicate refuses any other string with a model-addressed reason naming the legal set, so a branch/select author cannot smuggle an operator no cell implements.
