          ZUSAMMENFASSUNG - Gitea Complete Fix:
          ================================================================================
          
          Aktionen:
          - Gitea Runner: {% if runner_stop.changed | default(false) %}✅ Gestoppt{% else %}ℹ️  War nicht aktiv oder nicht gefunden{% endif %}
          - Gitea Restart: {% if gitea_restart.changed %}✅ Durchgeführt{% else %}ℹ️  Nicht nötig{% endif %}
          - Traefik Restart: {% if traefik_restart.changed %}✅ Durchgeführt{% else %}ℹ️  Nicht nötig{% endif %}
          
          Gitea Ready Check:
          - Direkt: {% if gitea_ready.rc == 0 %}✅ Bereit{% else %}❌ Nicht bereit{% endif %}
          
          Final Status:
          - Gitea via Traefik: {% if final_status.status == 200 %}✅ Erreichbar (Status: 200){% else %}❌ Nicht erreichbar (Status: {{ final_status.status | default('TIMEOUT') }}){% endif %}
          - Traefik Service Discovery: {% if 'NOT_FOUND' not in traefik_gitea_service_check.stdout %}✅ Gitea gefunden{% else %}❌ Gitea nicht gefunden{% endif %}
          
          {% if final_status.status == 200 and 'NOT_FOUND' not in traefik_gitea_service_check.stdout %}
          ✅ ERFOLG: Gitea ist jetzt über Traefik erreichbar!
          URL: {{ gitea_url }}
          
          Nächste Schritte:
          1. Teste Gitea im Browser: {{ gitea_url }}
          2. Wenn alles stabil läuft, kannst du den Runner wieder aktivieren:
             cd {{ gitea_runner_path }} && docker compose up -d gitea-runner
          3. Beobachte ob der Runner Gitea wieder überlastet
          {% else %}
          ⚠️  PROBLEM: Gitea ist noch nicht vollständig erreichbar
          
          Mögliche Ursachen:
          {% if final_status.status != 200 %}
          - Gitea antwortet nicht via Traefik (Status: {{ final_status.status | default('TIMEOUT') }})
          {% endif %}
          {% if 'NOT_FOUND' in traefik_gitea_service_check.stdout %}
          - Traefik Service Discovery hat Gitea noch nicht erkannt
          {% endif %}
          
          Nächste Schritte:
          1. Warte 1-2 Minuten und teste erneut: curl -k {{ gitea_url }}/api/healthz
          2. Prüfe Traefik-Logs: cd {{ traefik_stack_path }} && docker compose logs traefik --tail=50
          3. Prüfe Gitea-Logs: cd {{ gitea_stack_path }} && docker compose logs gitea --tail=50
          4. Prüfe Service Discovery: cd {{ traefik_stack_path }} && docker compose exec -T traefik traefik show providers docker
          {% endif %}
