~anthropic/claude-sonnet-latest → B (60:40)

Side B is a substantial architectural rework of URL canonicalization, replacing a combinator-based engine with a semantic graph/DFA approach and adding new parse/graph modules with updated docs and tests, representing meaningful design evolution in core logic. Side A adds a useful but small CLI feature (connectivity stats display) with modest tests, which is real but narrower in scope and impact compared to B's structural refactor of a core subsystem.
