• yaml.PathString parses JSONPath expressions for YAML supporting root ($), child traversal (.), array indexing ([n]), wildcards ([*]), recursive descent (..), and quoted keys (.'key').
• yaml.Path.Read streams and unmarshals target matched elements directly into Go primitives, structs, and slices from an io.Reader without intermediate document structures.
• yaml.Path.Read returns an error recognized by yaml.IsNotFoundNodeError when a queried path does not exist in the YAML document.
• yaml.PathString returns an error recognized by yaml.IsInvalidPathStringError when given malformed path syntax.
