Side A fixes user-facing URL generation by using `display_path()` for vote links instead of exposing stored canonical `https://slug.social/...` IDs, aligning hrefs with the displayed DSL paths. It also substantially strengthens the browser test by exercising all 45 pairwise votes in a 10-item pool and asserting the final ranking through `GetGardenRank`, providing end-to-end verification of ranking correctness. Side B is a useful type-safety refactor (returning `CanonicalItemUrl`, propagating typed paths, and adding `Deref`), but it is largely structural and does not introduce an equally direct functional improvement or behavioral guarantee.
