• The Descendants method only recurses into Alt sections and does not traverse children of other fragments (e.g., Interactions). To fully implement "query all descendants" behavior, add a default recursion branch after the switch that descends into node.Fragments.

                case Alt a:

• The summary for AddSection reads "Add a sections to this alt."—correct the grammar to "Add a section to this alt."

• The file uses LINQ methods (SelectMany, TakeWhile) but does not include using System.Linq;. Add the missing using System.Linq; directive to ensure the code compiles.
