Struct RequirementDecl 

pub struct RequirementDecl {
    pub name: Option<String>,
    pub name_span: Option<ExprSpan>,
    pub body: Expr,
    pub leading_comment: Option<Comment>,
    pub trailing_line_comment: Option<Comment>,
    pub blank_line_before: bool,
    pub span: ExprSpan,
}

requirement = [ "@" identifier ] expression ";".

name, when present, is a plain string label passed to adam_rs::Sheet::add_requirement, not a cell reference — it may coincide with a cell name declared elsewhere in the sheet but doesn’t have to.
