Side A adds a substantial new URL canonicalization subsystem: a graph-based traversal engine with declarative graph builder, URL parsing/normalization, generic fallback logic, breadcrumbs, and extensive tests covering Reddit, YouTube, encoding, query stripping, and traversal behavior. Side B mainly adds deployment infrastructure, production configuration, a live monitoring UI/SSE audit stream, and some robustness improvements (e.g. GitHub token support and deduplicated object verification), which are valuable operational enhancements but less foundational to the project's core behavior than the new canonicalization engine.
