Side A delivers multiple lasting functional improvements across the project: it adds a dedicated pairwise voting UI with incremental DOM morphing after votes, introduces robust pair resolution and bridge-aware pair selection, and fixes identifier normalization by adding ItemId::from_storage and using it throughout vote processing and Reddit import to avoid inconsistent IDs. Side B is a focused refinement of the existing pair-selection heuristic—adding better tie-breaking for attaching isolates and adjacent-rank refinement with tests—but it builds on infrastructure introduced by Side A rather than providing comparable new functionality or cross-cutting bug fixes.
