# Digital Twin Universe

The digital twin universe is StrongDM's reported local reproduction of enterprise SaaS systems used to validate generated software against realistic external behavior.

## Factory Role

It lets agents exercise code in a rich environment without touching production. This matters because dark factories need outcome evidence when humans stop reading every diff.

## Key Inference

`inference:` As code review declines, environment fidelity becomes a primary quality lever. A weak test environment turns "no human code reading" into blind trust; a strong twin makes automated validation more meaningful.
