A compiled, reusable schema validator. Create via compileSchema; then validate any number of instances of either built-in JSON type (or any custom-adapted type via validateWith).
Compare two JSON numbers exactly: integer representations never round-trip through a double; an integral/floating comparison is decided via floor().
Deep equality between two instance values of the same adapted type (uniqueItems), with cross-representation number equality.
JSON Schema multipleOf. Exact integer arithmetic when both operands are integral; otherwise a quotient-rounding check with a small relative tolerance (so 0.0075 is a multiple of 0.0001 despite binary representation).
Deep equality between an instance value (any adapter) and a schema-side JsonNode (for const / enum), with cross-representation number equality.
Annotation collector for one (schema, instance-location) evaluation: which object properties and array items have been successfully evaluated. This is what unevaluatedProperties / unevaluatedItems consult, after merging the collectors of all successful in-place applicator branches.
Instance validation: evaluating a compiled schema against a JSON value of any adapted type. Implements full 2020-12 evaluation semantics including annotation collection for unevaluatedProperties / unevaluatedItems and dynamic-scope resolution for $dynamicRef.
