The deterministic AS-TEST registry contains 10.0.0.0/24 but not 192.168.0.0/24. Ze builds the import prefix-list, accepts the registered route, rejects the unregistered route, and installs only 10.0.0.0/24 in Adj-RIB-In.

The operational commands use Ze's default text format. Its key/value layout resembles YAML, but YAML is only selected explicitly with `| yaml`.
