- secrets/ is now the private cc-ci-secrets repo (submodule). defaultSopsFile path unchanged.
- secrets.nix: add wildcard_cert/wildcard_key sops secrets -> path=/var/lib/ci-certs/live/*.
- proxy.nix: cert is sops-from-git, not an operator file drop (reframed; FATAL guard kept as decrypt-path check).
