/**
 * The single evaluator for a property's `visibleWhen` predicate — a static,
 * declarative field-visibility rule (scope B). The renderer (`ObjectFields`) and the
 * validator both call it so a field shown by the form is exactly the field validated at
 * submit, and a hidden field is neither rendered nor required. It reads only sibling
 * values already in the object; it never calls a consumer handler (that is scope A).
 *
 * A malformed predicate degrades to VISIBLE: the send-time server validation rejects a
 * malformed predicate loudly, so one never reaches a well-formed render, and showing a
 * field is the safe non-hiding default (a hidden-by-accident required field would dead-
 * end a form).
