~anthropic/claude-sonnet-latest → B (85:15)

B is a small, precise, correct bugfix that eliminates a real state-corruption bug (ghost items and falsely-marked voted pairs) and updates the test to verify the fix, with clear lasting value. A is a large feature/routing diff that also includes a nonsensical committed artifact (plan2.md, an AI chat transcript praising itself) which is noise rather than project value, undermining confidence in the commit's overall quality despite the real room-UI wiring work.
