Gossip-based failure detection is the single correctness bottleneck for the distributed cluster: replication, read repair, and hinted handoff all depend on its timeout-driven liveness set, which is bounded by cleanup to prevent unbounded membership growth.
All distributed data operations flow through the gossip liveness set, making failure detection accuracy a cluster-wide concern
