  • 44 util rows move to supported (42 from partial, 2 from not-implemented), closing every util.types predicate.
  • A module namespace and a compiled arguments object now answer their Node brand, a class extending Date answers isDate, and iterator helpers stop answering isGeneratorObject.
  • A JavaScript source's namespace keeps one object per module, so it has Node's identity and brand instead of a fresh copy per site.
