Fix Dynu brownfield generator output handling

infrastructure/terraform/dynu/README.md

@@ -70,3 +70,40 @@ The helper script writes these files under `generated/`:
 - `generated/import-dynu-dns-records.sh`
 
 These are generated outputs meant for operator review before use in production.
+
+## Troubleshooting
+
+### Error: `'"'"'dynu_dns_records'"'"'`
+
+Cause:
+
+The helper script reads `terraform output -json` and expects an output named `dynu_dns_records`.
+
+Fix:
+
+```bash
+cd infrastructure/terraform/dynu
+terraform init
+terraform apply -refresh-only
+terraform output -json | jq 'keys'
+```
+
+Confirm `dynu_dns_records` appears in the key list.
+
+If it does not, check that the Terraform config contains:
+
+```hcl
+data "dynu_dns_records" "root" {
+  hostname = var.dynu_root_domain
+}
+
+output "dynu_dns_records" {
+  value = data.dynu_dns_records.root.records
+}
+```
+
+Then rerun:
+
+```bash
+python3 scripts/generate-brownfield-records.py --dry-run
+```
