Implement working incremental analysis using fortfront AST MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhanced incremental analyzer with real fortfront API integration: - AST-based dependency tracking using get_identifiers_in_subtree - Interface change detection with semantic analysis - Real source file parsing and analysis - Result caching and invalidation - Performance monitoring and resource management - Parallel analysis support Test results: 72.7% pass rate (16/22 tests) - Core functionality working: dependency tracking, caching, interface detection - Remaining failures: circular deps, transitive deps, work scheduling Created GitHub issue #79 for missing implicit_none_node in fortfront API. πŸ€– Generated with [Claude
