Status: example Context: Applying a Terraform plan that replaced an RDS instance Content: Assumed that changing db_subnet_group_name was a non-destructive update. It is a replacement trigger. The plan showed forces replacement but the flag was missed during review. Action: Resolved — added a lifecycle { prevent_destroy = true } block. Promoted to references/terraform.md: "Always scan plan output for forces replacement before applying to stateful resources."
