~anthropic/claude-sonnet-latest → B (55:45)

B fixes a real correctness bug (ghost items and falsely-marked voted pairs from zero-ratio votes) with a minimal, precise change and updates the test to verify the corrected invariant. A adds a legitimate new feature with good test coverage, but B's change addresses actual data-integrity bugs in core reducer logic that could silently corrupt state, which has more lasting correctness value than an additive feature.
