Side A performs a substantive architectural refactor of URL canonicalization, replacing an ad-hoc per-domain function engine with a more general DFA/graph-based approach, while preserving/adapting existing tests to validate correctness. Side B is a small, focused UI bugfix (splitting unranked siblings into separate groups) with a single new test, which is real but much smaller in scope and lasting impact.
