% SECTION 4: Multi-level Inheritance Examples
% ============================================================================
% Multi-level chains use real-world examples defined above:
% - 3-level: cgal → cgal:5-0-2 → cgal:lp-gi-20a (defined in Section 2)
% - 4-level: parmap → parmap-1.1.1 → parmap-module-core → parmap-fragment-from-module (defined in Section 3)
% No additional entries needed for multi-level examples

% ============================================================================
% SECTION 5: Edge Cases and Special Scenarios
% ============================================================================
% These synthetic examples are kept for pedagogical demonstration of edge cases
% that may not exist in real-world data

% Example with editor field

  version = {1.0}
}
