Class: LogicalPredicate

A reusable, composable, and nestable logical expression resolving to a boolean. Used for applicability conditions, validation rules, eligibility criteria, and skip logic. This is a data-model predicate — not a clinical condition (diagnosis). Implements usdm:Condition (the study-design predicate, distinct from the clinical FHIR Condition resource).
