The C# syntax tree's name accessors (ParameterDeclaration.Name, GotoStatement.Label, catch variable, query continuations, ...) are convenience strings over a backing Identifier token. Names that may be absent are now typed string? and read as null when absent, instead of a non-null empty-string sentinel; required names stay non-null string. The backing token slot's nullability follows, and an empty or null assignment clears the token (empty == absent). Because the property type now carries optionality, the separate [NameSlot] attribute and its nullOnEmpty flag are redundant: a [Slot] on a string property is a name (child slots are AstNode-typed, so the type disambiguates), and the generator infers optionality from the declared nullable annotation -- which a string? declaration already requires #nullable for. The repeated empty-to-null setter body becomes Identifier.CreateIfNotEmpty. To make the annotation readable, #nullable enable is turned on across the syntax node files (the directive the inferred optionality depends on), with the attendant local nullability fixups. Consumers that feed a name into a non-null slot assert it where the variable structurally has a name. Assisted-by: Claude:claude-opus-4-8:Claude Code
