+ * graph-node label for class members. Without this realignment,
+ * `resolveDefGraphId`'s parameter-typed key lookup (gated on
+ * `def.type === 'Method'`) falls through to the simple-name fallback
+ * for class methods, collapsing same-name same-arity overloads onto
+ * the first-registered node (#1761).
+ *
+ * Only Method-bearing types are touched. Methods have a class owner
+ * (set by `populateClassOwnedMembers`) and a class-qualified name.
