Side A ships a working, self-contained feature (grouped cli_panel UI with hover-to-copy, JS-injection safety assert, CSS updates) that compiles and improves real user-facing behavior across multiple call sites. Side B is almost entirely a large planning markdown document plus an unused/unwired RouteContext scaffold that duplicates ThreadNav without migrating any call sites, providing no concrete functional or architectural change yet.
