Что обычно предполагают

Unmarshaling a YAML mapping directly into *yaml.Node produces a MappingNode whose Content slice holds child values.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

Контракт

• yaml.Unmarshal into *yaml.Node produces a root DocumentNode with Kind 1 whose Content slice wraps the top-level MappingNode (Kind 4) at index 0 rather than returning a MappingNode directly.
• MappingNode.Content is a flat slice of 2*N nodes where even indices hold key scalar nodes and odd indices hold value nodes.
• HeadComment annotations attach to key nodes while inline LineComment annotations attach to value nodes.
• yaml.Node.Decode decodes AST subtrees directly into Go struct types.
• In-place AST scalar modifications preserve HeadComment and LineComment annotations across yaml.Encoder serialization.
• Types implementing UnmarshalYAML(value *yaml.Node) receive AST position metadata (Line and Column) and can decode underlying values via value.Decode.
