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

B ships a concrete, testable feature (clickable unpin from ranked child groups) with a real backend/UI flow change plus an expanded browser test covering the new interaction end-to-end. A is a legitimate bugfix with good unit tests, but it also introduces a large CSS regression (fixed 3-way slider gradient with hardcoded 50% midpoints that breaks the actual slider value display, contradicting its own JS which still sets --vote-slider-pct dynamically), making its visual fix partially inconsistent, whereas B's change is self-contained and verified more thoroughly.
