Function read_catalog_array_input 

pub fn read_catalog_array_input(
    text: &str,
    target: &ColumnType,
    engine: &dyn EngineHook,
) -> Result<Value>

Read an array whose elements are domains with the same input and constraint path as a catalog-aware cast. The resolved target preserves domain identity; a scalar outer domain remains the surrounding expression’s runtime coercion.
