Side A fixes a substantive correctness bug by removing shared browser sentinel delegates, changing pending sessions to use an optional delegate, updating attribution logic, and adding integration tests proving multiple browser users can vote independently without erroneous AgentBound conflicts. Side B introduces a substantial new vote-compare UI flow and related refactoring, but much of it is feature work and infrastructure rather than resolving an existing correctness issue, making A's bugfix more durable and fundamental.
