openai/gpt-5.2-chat → B (100:1)

Side B introduces a substantial new URL canonicalization subsystem: multiple new modules (graph, graph_builder, parse, registry tests), ~1000+ lines of production and test code, a DFA-based semantic graph, generic fallback logic, and extensive unit and integration tests covering Reddit, YouTube, and generic sites. Side A is a tiny ‘nit’ change removing form attributes (a small simplification of a single HTML form). The scope, architectural impact, and test coverage of B overwhelmingly exceed A.
