Mempool Cluster Limits

ops.mempool-cluster-limits

Bitcoin Core limits each connected mempool cluster to a bounded transaction count and aggregate virtual size, replacing legacy ancestor and descendant limits so package admission, relay, replacement, and block-selection decisions remain computationally tractable.
