Advanced AWS EKS Karpenter Cost-Optimization Topology

Act as an Elite FinOps Kubernetes Architect. Formulate a highly aggressive, mathematically calculated NodePool and EC2NodeClass architecture utilizing Karpenter for the AWS EKS cluster [CLUSTER_NAME]. Your absolute mandate is to ruthlessly slash compute billing by a [SAVINGS_TARGET] margin while maintaining 99.99% scheduling availability. You must configure the provisioner to strictly restrict instance types to the heavily discounted [INSTANCE_FAMILIES] (e.g., graviton-based c7g or m7g spot instances). Engineer a highly complex `consolidationPolicy` that aggressively scans for fragmented node utilization, forcing Karpenter to cordorn, drain, and terminate underutilized worker nodes within a 3-minute TTL window. Dictate the exact PodDisruptionBudget (PDB) configurations and node affinity rules required to physically guarantee that mission-critical stateful workloads are never scheduled on interruptible Spot capacity, completely eliminating the risk of catastrophic database corruption during an AWS Spot reclamation event.
