Side A introduces a substantial new URL canonicalization subsystem: a semantic graph/DFA with a declarative graph builder, URL parsing and normalization, generic fallback logic, breadcrumb generation, and extensive tests covering Reddit, YouTube, and generic URLs. Side B makes useful architectural cleanup by removing the demo counter, adding an asynchronous settlement worker and cached ranking path, but much of the patch is refactoring and feature removal, whereas Side A adds a lasting core capability with validation and broad test coverage.
