Derive WARP Routes from Infrastructure

Private-network configuration drifts easily when the network is defined in Terraform but WARP routing is maintained manually somewhere else.

In my multi-cloud lab, a dedicated Terraform module calculates the routing subnets needed by the environment and exposes them as outputs.

The useful pattern is:

Cloud network definitions
        ↓
Terraform subnet values
        ↓
Routing calculation
        ↓
WARP / Zero Trust configuration

That does not mean every client policy must be generated automatically. It means I prefer infrastructure data to be the input when the same values are already authoritative elsewhere.

The alternative is duplication:

Terraform says subnet A exists
manual WARP list says subnet B exists

Once those two copies diverge, troubleshooting becomes much harder.
