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

B performs a substantial, coherent refactor centralizing path/URL logic into a shared `slug-types` crate with strongly-typed newtypes (GardenItemUrl, ForumThreadUrl, TildeOntologyPath), improving correctness-by-construction and reducing duplicated string-formatting logic across server and RPC code, while preserving existing tests. A fixes a real bug (Reddit children not linked via ensure_path, causing unranked labels to show raw ids) with a small targeted change plus test coverage, which is valuable but narrower in scope and reach than B's broader architectural improvement that touches many call sites and eliminates fragile string-based path handling project-wide.
