Operator 2026-09-07: the combined host stays off the tailnet. ssh is
key-only (password + keyboard-interactive auth off), the opencode UI is
served as oc.ci.commoninternet.net on 8443 — TLS from the CI server's
*.ci.commoninternet.net ACME cert (new orchestrator-host option
opencodeUiAcmeHost; nginx joins the acme group) behind the existing basic
auth — and fail2ban watches sshd plus nginx's 401s (nginx-http-auth jail).
tailscaled ordering dropped from the orchestrator units. README updated.

Found on the first activation of #cc-ci on 195.201.88.249: the opencode
installer lands in ~/.opencode/bin (opencode-web then failed at EXEC), and
nginx's pre-start config check runs as the nginx user, so the staged
cert/htpasswd must be root:nginx 0640, not root:root 0600.

hardware.nix / networking.nix are now the nixos-infect output of
195.201.88.249 (ESP E079-7D41, eth0 MAC-pinned), with the one edit that
matters: defaultGateway as an attrset with interface = "eth0".
README §2a records what it actually took to get NixOS running on the
Debian 13 image: NO_SWAP=true (tmpfs /tmp), a manual lustration from rescue
mode because 26.05's systemd initrd did not honour NIXOS_LUSTRATE (Debian's
unit files shadowed every NixOS service), and the gateway fix applied via a
chroot rebuild with the nix sandbox off.
flake: cc-ci input back on main (PR #32 merged as f6dbfa3); loops uid pinned
to 1000 so workspace rsyncs by uid line up.

The orchestrator's flake now builds the machine it shares with the cc-ci CI
server: `nixosConfigurations.cc-ci` composes cc-ci's nixosModules.cc-ci-server
(new flake input, nixpkgs + sops-nix follow ours), this repo's orchestrator
module (nix/modules/cc-ci.nix, exported as cc-ci-orchestrator, `cc-ci` kept
as an alias for notplants-nix) and the new nix/modules/orchestrator-host.nix
— the host contract those units always assumed (loops user, claude/opencode
CLIs, opencode web server + tailnet-only UI on 8443 since traefik owns
80/443, nix-ld, tool set, `ssh cc-ci` → loopback).
nix/hosts/cc-ci/{hardware,networking}.nix are PROVISIONAL copies of the old
server's layout so the flake evaluates; they get replaced by the
nixos-infect output of 195.201.88.249.
README.md is the deploy guide (Hetzner Debian → nixos-infect → this flake →
staging → data restore → cutover). archive/ holds the retired Incus/Hetzner
orchestrator host configs, the old terraform and the migration plans;
references updated. cc-ci-plan/plan-cc-ci-combined-host.md is the working
plan for the move.
