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

Side A fixes a genuine multi-user correctness bug (shared sentinel delegate silently locking out other human voters) with a minimal, well-scoped change plus a targeted regression test proving the fix. Side B also fixes a real bug (inconsistent canonical root path causing lookup mismatches) but does so with a much larger, more invasive refactor across path types touching many call sites, which carries more risk despite good test coverage; both are solid but A's fix is more surgical and addresses a more severe functional defect (broken voting) with lower blast radius.
