The nodeResources filter examples incorrectly used `allocatableMemory` instead of `memoryAllocatable`. This causes YAML parsing to silently ignore the field, resulting in empty filter values and unexpected analyzer behavior. Changed in 3 files (5 instances total): - examples/preflight/node-resources.yaml (3 instances) - examples/preflight/e2e.yaml (1 instance) - examples/support-bundle/e2e.yaml (1 instance) The correct field names according to pkg/apis/troubleshoot/v1beta2/analyzer_shared.go are: - memoryAllocatable (not allocatableMemory) - cpuAllocatable (not allocatableCPU) - memoryCapacity (not capacityMemory) - cpuCapacity (not capacityCPU) This bug caused users copying from these examples to experience false failures in preflight checks, as documented in the bug report where a GKE cluster with 85Gi memory failed a check requiring only 8Gi.
