Side A introduces a new URL parsing and semantic graph framework with generic canonicalization, breadcrumb generation, graph validation via a builder, host/query normalization, and extensive tests. Side B adds useful OAuth functionality (Reddit provider support, UUID-centered account linking, projection fixes, and UI updates), but it extends an existing authentication system, whereas Side A establishes a broader reusable architecture for URL canonicalization that is likely to underpin future URL rules and behavior.
