  "context": "Evaluates whether the agent applies the two cross-cutting Terraform IaC patterns that appear in every policy: using import rego.v1 (not import future.keywords) and normalizing input with tfplan := object.get(input, \"plan\", input) so the policy works with both raw Terraform and HCP Terraform/Enterprise input structures. These criteria are tested here and excluded from all other terraform IaC scenarios to avoid inflating their scores.",
