~anthropic/claude-sonnet-latest → B (6:4)

Side B is a focused, well-tested algorithmic refinement to pair selection (established-component merging, isolate attachment, and rank-zip refinement) that improves a core ranking heuristic with clear new unit tests. Side A is a broader but more diffuse refactor mixing UI morphing, a new vote-compare page, ItemId normalization changes, and test infra shuffling, which adds real functionality but is riskier/noisier and less singularly focused than B's targeted improvement to existing logic.
