The validation module already implemented the composable-rule idiom under its own names (Check/Issue/SubjectContext) and a value-type Validator with duplicated traversal machinery per layer. Renamed the core types to the canonical names (Validation/ValidationError/ValidationErrorCollection/ ValidationContext/BuiltinValidation/AnyValidation), converted Validator to a reference-type class with the two-tier default-rule split, and genericized it over both Subject and Document via a new Traversable protocol so the model and tagged layers share one walk engine instead of two copies. Wired the JSON-representability rule set into the same shape and closed the two missing pieces (unwrap combinator, JSON coverage/config-pin tests).
