Remove the Clay role (Claude Code web UI) and its Anthropic API key. New roles: - ollama: local CPU LLM (qwen3:4b-instruct), internal network only - browserless: headless Chromium for JavaScript-heavy pages - searxng: metasearch backend for the chat web_search tool - n8n at agent.ladkau.de: web chat (/chat), scheduled workflows, Telegram bot; workflows and credentials are imported from the repo Telegram bot: Gemini 3.8 -> Gemini 3.5 -> local Qwen fallback chain, /qwen to force the local model, /stocks and a weekday schedule (07:30, 13:00, 17:40) for the MTE.DE / PTX.F stock report. Also: dashboard and check-services entries for the chat, vault checks for the new secrets (n8n, SearXNG, Gemini, Telegram, SMTP), updated CLAUDE.md, runbooks and README.

Purpose:
This repository tracks the complete server configuration so the server can be fully reinstalled from scratch using only this repo. Every configuration change must be committed here. The git history serves as the change log.
Architecture:
Provisioning: Ansible Ansible playbooks configure the OS and deploy all services. Roles are idempotent — re-running them brings the server back to the desired state without side effects. The master playbook is ansible/site.yml.
Service runtime: Docker Compose Each service runs as a Docker Compose stack. Compose files live inside their respective Ansible roles (roles//templates/docker-compose.yml.j2). This keeps service definition and deployment config together.
Reverse proxy / TLS: Traefik Traefik is the single entry point for all HTTP/HTTPS traffic. It runs as a Docker Compose service and routes to other containers via Docker labels. TLS certificates are issued automatically via Let's Encrypt (ACME).
