Struct SchemaField 

pub struct SchemaField {
    pub typ: ActiveType,
    pub min: Option<NodeId>,
    pub max: Option<NodeId>,
    pub min_len: Option<NodeId>,
    pub max_len: Option<NodeId>,
    pub pattern: Option<NodeId>,
    pub default: Option<NodeId>,
    pub deprecated: Option<String>,
    pub span: Option<Span>,
}

One field’s schema: a type plus its constraint arguments (spec §2.10, C-030). Constraint values are expression nodes so bounds may use literals, env refs, and arithmetic; C-031 evaluates them during validation. default is parsed and stored; C-032 applies it. deprecated is static text (C-042): None is live, Some("") is a bare deprecated = true, Some(msg) carries the migration message.
