## Key Patterns Observed

1. **Most clusters** use `dedicated` key for taints/tolerations with values matching the contour instance name
2. **GKE Autopilot clusters** (k8s-central-prd-ase1, k8s-dsgpu-prd-ase1, k8s-shared-int-ase1) use `cloud.google.com/compute-class`
3. **cert-checker** components use `<cluster-name>-devops` toleration values
4. **Some clusters** have multiple tolerations for migration/shared scheduling (e.g., `contour-shared`, `contour-internal-1-new`)
5. **k8s-aurva-prd-ase1** is the only cluster without any nodeSelector/tolerations for contour
