Auf Basis des Grilling-Sessions mit 20 design decisions umgesetztes v1-Skeleton der Thin-Client-Rolle plus 3 Pilot-Hosts. Architektur: - roles/thin-client/ als geschlossene Rolle (default.nix compose + 7 Subdirectories: hardware, session, identity, network, peripherals, apps, monitoring, deployment) - hosts/AZ-TC-NN/default.nix als ~20-Zeilen-Wrapper pro Fleet-Host - flake.nix instanziiert AZ-TC-01..03 via Fleet-Helper - secrets.nix mit per-host agenix-Secret-Stubs Submodule: - hardware: dell-optiplex-micro + generic-x86_64-uefi Fallback - identity: AD (sssd/krb5/keytab via agenix), lokale Notfalluser (sascha.koenig + jannik.mueller ohne m3ta-home), sudo-Policy - session: KDE Plasma 6 + Wayland + SDDM, Branding (Wallpaper + Footer), PipeWire Audio - network: NetworkManager + wpa_supplicant + 802.1X EAP-TLS, NetBird + SSH via NetBird, systemd-resolved (Corp + NetBird DNS), hardened firewall, OpenSSH - peripherals: CUPS mit Pull-Print-Queue, pam_mount für DFS-Shares - apps: Chromium (ManagedBookmarks, Bitwarden force-install, no local passwords), Office-Web .desktop-Shortcuts, Remmina (mehrere TS, Kerberos SSO), RustDesk Client + Daemon, OBS Studio, Autostart - monitoring: node_exporter → Pushgateway, Alloy (stub für Loki), Snipe-IT Asset-Checkin (stub) - deployment: Disko BTRFS-Layout, auto-upgrade daily + reboot window, snapper snapshots Build-Validierung: 'nix flake check' bestanden für AZ-TC-01/02/03. Siehe roles/thin-client/README.md für den Provisionierungs-Workflow und die Liste der noch auszufüllenden Platzhalter (TODO-Kommentare in den jeweiligen Modulen).
