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

Side B fixes a real concurrency bug where a shared sentinel delegate blocked every human user after the first browser vote, with a targeted multi-file fix and a new integration test proving two users can vote independently. Side A adds a genuinely useful feature (pool-scoped voting) but is purely additive UI/UX without addressing any correctness defect, making B's change more critical to actual product correctness.
