Diagnose and resolve a split-brain scenario in a distributed database cluster where a network partition has caused two nodes to independently accept writes, leading to data divergence and consistency violations.
## Problem
Your 5-node distributed database cluster has experienced a network partition. For 45 minutes, the cluster was split into a 2-node group and a 3-node group, and both groups independently accepted writes. The partition has now healed, but the cluster is in an inconsistent state with conflicting data on each side. Diagnose how the split-brain occurred, assess the data divergence, and design a reconciliation plan.
