~anthropic/claude-sonnet-latest → B (6:4)

Side A is purely a planning document plus a thin, unused RouteContext wrapper with no call-site migration or tests exercising it. Side B ships an actual working feature (parser/parser_action/parser_render modules, wired into ui_action, HTML mod, JS, and covered by new integration and Clojure smoke tests), representing real functional code that lands and is verified, despite also containing some churn (legacy file removal, .gitignore tweak).
