A Rule was exactly a Check<Model.Value, Model.Value>: it fired on every node, switched on the value itself, and carried the root. It was therefore a second copy of the one check machinery, the duplication the validation idiom exists to prevent (principle 10), now also resolved for the tagged layer. Remove Rule and its Context. The model validator holds only checks; its default is the type-directed BuiltinCheck.mappingKeysAreUnique; validating takes a Check. Custom whole-tree rules become Check<Model.Value, Model.Value> with the former context.root now context.document. Behaviour is byte-identical: the mapping-key builtin reports the same issues at the same paths in the same DFS order, so the public validate/collect/blank surface is unchanged. All 399 tests pass; the coverage gate reconciles to 60 public types.
