- Both Listener and Visitor patterns achieve identical 98.4% pass rate - 6 remaining failing tests to reach 99.7% target: 1. Markdown formatting in subgraphs (1 test) 2. Multi line strings YAML processing (2 tests) 3. Node data YAML processing (2 tests) - @ syntax in ampersand chains 4. Accessibility description parsing (1 test) - Significant progress from previous baselines - Ready to tackle remaining issues systematically
