Rewrite: Python → Go + Observable Framework - Single binary distribution (Go with embedded static assets) - Observable Framework dashboard replacing vanilla HTML/JS - D3 visualizations: chord diagram, treemap, circle packing, heatmap, file network - New metrics: compression ratio, distinct-n, instruction density, vocab overlap, specificity - Hand-rolled TF-IDF vectorizer (no external dependencies) - Multi-granularity chunking (document, section, paragraph, rule, sentence) - Cross-platform builds via GitLab CI
