The engagement
Production had been built by hand over five years. Nobody could recreate it, and the one person who understood the load balancer rules had left.
We imported the live environment into Terraform state piece by piece, verifying each plan produced no diff before moving on, then rebuilt staging from the same modules to prove reproducibility.
The team now creates a full preview environment per pull request and tears it down on merge.
