+// COMPILED TWINS for the transform tests' source-string fixtures. The transformer decides
+// "is this whole type NEW?" by looking the class up in the compilation's references
+// (SourceCodeTransformer.FindCompiledType) — a type with no compiled twin gets every method
+// co-emitted and its receiver parameter degraded to `object` (it exists in no reference).
+// The tests' fixtures describe the NORMAL live-edit flow, where the type IS compiled in the
+// running build, so their twins must exist here — with the same method names, or those
+// methods would classify as newly added instead of overrides.
+//
+// Nothing instantiates these; only their metadata matters.
