Overview

receiver.all? { |x| PREDICATE } / .any? { ... } / .none? { ... } -- vendored addition, not (yet) upstream hecks (migration plan task 9), completing the same Phrase four-segment invariant the Split node above was built for (value.split("::").all? { |s| s.length > 0 }). Structurally different from every other addition in this file: every prior suffix is a flat receiver -> scalar transform, but a block predicate needs to evaluate its own sub-expression ONCE PER ELEMENT with the block parameter bound to that element. Kept minimal per the migration plan's own instruction -- no persistent iteration-variable concept added to Resolver's state model at all ; predicate below is a fully-parsed EVALUATOR ast (not a Resolver ast -- the predicate is a boolean/comparison expression like s.length > 0, exactly the grammar Bluebook::Expression::Evaluator owns, not this module's own leaf grammar), parsed once at parse-time same as every sibling node's sub-expressions are. mode distinguishes all?/any?/none? without three duplicated node types, since their only difference is which Array predicate aggregates the per-element results (interpret_with_element, below, is the "smallest correct thing" the plan asked for -- it threads the element binding through a temporarily-extended attrs hash for that one predicate's evaluation only, never touching interpret's own signature or any other node's call sites). Resolver already calls into Evaluator elsewhere in this file (sign_test_node/apply_sign_test call Evaluator. apply/Evaluator::OPERATORS directly) -- this is the same precedented cross-reference, not a new coupling.
