 The canonical local proof path is the six-node VM cluster under [`nix/test-cluster`](/home/centra/cloud/nix/test-cluster/README.md). It builds all guest images on the host, boots them as hardware-like QEMU nodes, and validates real multi-node behavior.

-PhotonCloud is centered on reproducible infrastructure behavior rather than polished end-user product surfaces. Some services, such as `creditservice`, are intentionally minimal reference implementations that prove integration points rather than full products.
+UltraCloud is centered on reproducible infrastructure behavior rather than polished end-user product surfaces. Some services, such as `creditservice`, are intentionally minimal reference implementations that prove integration points rather than full products.
 
 Host-level NixOS rollout validation is also expected to stay reproducible: the `deployer-vm-smoke` VM test now proves that `nix-agent` can activate a prebuilt target system closure directly, without recompiling the stack inside the guest.
