       "answer": "These subsystems primarily contain Helm charts with Go-templated YAML, Terraform HCL, and Crossplane compositions. The code analysis pipeline detects functions/modules from Python, Go, TypeScript, and shell scripts — but Helm templates use Go template syntax ({{ }}) which doesn't produce traditional function/module entities. Their content is captured through the Helm chart extraction phase instead.",
