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

Side A fixes a real multi-user correctness bug (shared sentinel delegate blocking subsequent voters) with a broad, coherent change across CLI, server, types, and tests, including a targeted integration test proving the fix. Side B is a smaller, valid reducer fix (moving a zero-ratio guard earlier to avoid ghost items), which is correct but narrower in scope and impact than A's fix to a user-facing multi-tenant blocker.
