+# 🛠️ Guide: Conveyor Installation
+
+Dieses Dokument beschreibt die Installation von **Hydraulic Conveyor** auf verschiedenen Linux-Distributionen (Ubuntu
+26.04 und Fedora 44).
+
+---
+
+## 1. Ubuntu 26.04 (Debian-basiert)
+
+Der am einfachsten Weg für Ubuntu ist der direkte Download des `.deb`-Pakets. Dieses konfiguriert bei der Installation
+automatisch das APT-Repository für zukünftige Updates.
+
+### Installation via .deb (Empfohlen)
+
+```bash
+# Aktuelles Paket herunterladen (Beispiel v12.0 - bitte Version ggf. anpassen)
+VERSION="12.0"
+curl -L https://downloads.hydraulic.dev/conveyor/conveyor_${VERSION}_amd64.deb -o conveyor.deb
+
+# Installieren (konfiguriert auch das Repo automatisch)
+sudo apt update
+sudo apt install ./conveyor.deb
+```
+
+---
+
+## 2. Fedora 44 (RPM-basiert)
+
+Für Fedora wird die Installation via Tarball empfohlen, da Conveyor als autarkes Binary geliefert wird.
+
+### Installation via Tarball (Systemweit)
+
+Dies ist der zuverlässigste Weg für Fedora:
+
+```bash
+# Version definieren (Beispiel v12.0, bitte aktuelle Version prüfen)
+VERSION="12.0"
+curl -L https://downloads.hydraulic.dev/conveyor/conveyor-${VERSION}-linux-amd64.tar.gz -o conveyor.tar.gz
+
+# Entpacken nach /opt
+sudo tar -xzf conveyor.tar.gz -C /opt/
+sudo ln -s /opt/conveyor-${VERSION}/bin/conveyor /usr/local/bin/conveyor
+
+# Test
+conveyor --version
+```
+
+### Installation via RPM (Falls verfügbar)
+
+Prüfen Sie auf der Hydraulic Website, ob mittlerweile ein natives RPM-Repository existiert. Falls ja:
+
+```bash
+sudo dnf config-manager --add-repo https://conveyor.hydraulic.dev/rpm/conveyor.repo
+sudo dnf install conveyor
+```
+
+---
+
+## 3. Post-Installation & Verifikation
+
+Nach der Installation sollten Sie den Pfad und die Version prüfen:
+
+```bash
+conveyor --version
+```
+
+### Root-Key Initialisierung
+
+Beim ersten Ausführen von `conveyor` wird ein Root-Key generiert. **Sichern Sie diesen unbedingt!**
+
+```bash
+conveyor make site
+```
+
+*Folgen Sie den Anweisungen im Terminal zur Sicherung des Root-Keys.*
+
+---
+
+## 4. Troubleshooting
+
+### Fehlende Bibliotheken (Fedora)
+
+Falls Conveyor native Hilfe benötigt (z.B. für Icons oder Kompression):
+
+```bash
+sudo dnf install libX11 libXext libXrender
+```
+
+### Berechtigungen
+
+Stellen Sie sicher, dass Ihr Benutzer in der Gruppe `docker` ist, falls Sie Conveyor innerhalb von Containern nutzen
+oder Docker-basierte Inputs verwenden (für dieses Projekt primär lokal relevant).

+Dieses Dokument beschreibt den professionellen Packaging-Prozess für die Meldestelle Desktop App. Wir nutzen **Conveyor** als primäres Werkzeug für das Cross-Platform Packaging (Windows, Linux, macOS), da es stabile Installer inklusive signierter Updates und gebündelter JREs erzeugt.

-
-## 3. Cross-Packaging mit Conveyor
-
-Conveyor nutzt die kompilierte JAR-Datei und schnürt daraus Pakete für alle Zielplattformen.
-
-### Schritt 1: JAR erstellen
-```bash
-./gradlew :frontend:shells:meldestelle-desktop:jvmJar
-```
-
-### Schritt 2: Pakete bauen
-```bash
-# Erstellt den Windows-Installer und die HTML-Downloadseite
+# Komplette Release-Site (Windows & Linux)
 conveyor make site
+
+# Nur ein spezifisches Paket (schneller für Tests)
+conveyor make debian-package   # Linux .deb
+conveyor make windows-msix      # Windows .msix
 ```
 
-### Schritt 3: Ergebnisse
-Die fertigen Installer (z.B. `.msi` für Windows) befinden sich im neu erstellten Ordner `output/`.
+Die Ergebnisse liegen im Ordner `output/`.
 
 ---
 
-## 4. Problembehandlung & Optimierung
+## 3. Konfiguration (`conveyor.conf`)
 
-### Native Access Warnungen
-Die App benötigt Zugriff auf native Bibliotheken (Netty/SQLite). Der notwendige Parameter `--enable-native-access=ALL-UNNAMED` ist bereits fest hinterlegt.
+Wichtige Parameter der aktuellen Konfiguration (v1.0.1):
+*   **JDK:** Nutzt `Amazon Corretto 21` für maximale Cross-Platform Stabilität.
+*   **Heap-Size:** Erhöht auf `-Xmx1024m`, um auch große Stammdaten-Importe zu bewältigen.
+*   **Linux-Deps:** Automatische Installation von `libasound2`, `libgl1-mesa-glx` und `libx11-6`.
+*   **Native Access:** `--enable-native-access=ALL-UNNAMED` ist für Netty/SQLite aktiviert.
 
-### Firewall-Konfiguration
-Für Netzwerk-Tests (Discovery/Chat) müssen die Ports 8090, 8080 und 5353 (UDP) geöffnet sein.
-Nutzen Sie dafür das bereitgestellte Skript:
+---
+
+## 4. Netzwerk & Sicherheit (WICHTIG)
+
+Damit die P2P-Funktionen (Chat, Discovery, Sync) nach der Installation funktionieren, müssen folgende Ports auf dem Host-System offen sein:
+
+| Port | Protokoll | Funktion |
+| :--- | :--- | :--- |
+| **8080** | TCP | P2P Sync & Datenabgleich |
+| **8090** | TCP | Veranstaltungs-Chat (WebSocket) |
+| **5353** | UDP | mDNS Discovery (Geräte finden) |
+
+### Firewall-Einrichtung (Linux)
+Nutzen Sie das optimierte Setup-Script:
 ```bash
 sudo ./setup-firewall-linux.sh
 ```
+
+### Windows-Besonderheit
+Beim ersten Start der `.msix` App wird Windows fragen, ob der Netzwerkzugriff erlaubt werden soll. **Wichtig:** Sowohl "Private" als auch "Öffentliche" Netzwerke anhaken, falls auf Turnieren oft Gast-WLANs oder Hotspots genutzt werden.
+
+---
+
+## 5. Troubleshooting
+
+### Problem: "No main class specified"
+**Lösung:** Stellen Sie sicher, dass in der `Main.kt` eine saubere Top-Level `fun main()` existiert und in der `conveyor.conf` auf `at.mocode.frontend.shell.desktop.MainKt` verwiesen wird.
+
+### Problem: SQLite / Native Libs laden nicht
+**Lösung:** Prüfen Sie, ob `extract-native-libraries.conf` in der `conveyor.conf` inkludiert ist.
+
+### Problem: JmDNS findet keine Teilnehmer
+**Lösung:** Prüfen Sie die Ports via `ss -tulpn`. Auf Linux blockieren oft Docker-Interfaces (`br-*`) den Broadcast. Die App filtert diese nun automatisch, aber ein aktives `setup-firewall-linux.sh` ist zwingend erforderlich.
+
+## 6. Performance-Optimierung (Gradle)
+
+Der Build-Prozess kann bei aktivierter Web-Kompilierung (WASM/JS) sehr lange dauern. Für die reine Desktop-Entwicklung
+wurde WASM standardmäßig deaktiviert.
+
+* **WASM aktivieren (z.B. für CI/Portal):** `./gradlew -PenableWasm=true ...`
+* **WASM deaktivieren (Default):** `./gradlew ...` (Spart bis zu 70% Build-Zeit).
+
+## 7. Gradle Deep-Optimierung
+
+Neben dem Deaktivieren von WASM wurden folgende systemweite Optimierungen in der `gradle.properties` vorgenommen:
+
+* **Configuration Cache:** Aktiviert. Gradle merkt sich die Projektstruktur, was den Start jedes Befehls um Sekunden bis
+  Minuten verkürzt.
+* **JVM G1GC & 12GB Heap:** Optimiert für große Multi-Modul-Projekte auf Systemen mit viel RAM (ab 16GB).
+* **Parallel Workers:** Erhöht auf 12, um die 16 logischen Kerne Ihres Rechners besser auszulasten.
+
+### Optionale Analysen
+
+Statische Analysen sind nun standardmäßig **deaktiviert**, um den täglichen Workflow nicht zu bremsen.
+
+* **Analyse laufen lassen:** `./gradlew staticAnalysis -PrunStaticAnalysis=true`
+* **Dokka Dokumentation bauen:** `./gradlew dokkaAll -PrunDokka=true`
+
+Stellen Sie in der `gradle.properties` sicher, dass `enableWasm=false` gesetzt ist, wenn Sie primär an der Desktop-App
+arbeiten.

+# 🧹 Journal: Build-Performance & Conveyor Installation
+
+**Datum:** 11. Mai 2026
+**Agent:** 🏗️ [Lead Architect] & 🧹 [Curator]
+
+## 📝 Zusammenfassung
+
+Der Fokus dieser Session lag auf der Optimierung der Gradle-Build-Performance und der Unterstützung des Users beim
+Wechsel auf einen neuen Entwicklungsrechner (Ubuntu 26.04). Dabei wurde ein Fehler in der GPG-Key-URL von Conveyor
+behoben.
+
+## 🚀 Erledigte Aufgaben
+
+1. **Gradle Performance Boost:**
+  * `enableWasm` in `gradle.properties` wurde standardmäßig auf `false` gesetzt.
+  * Dies deaktiviert die zeitintensive Kompilation von Kotlin/JS und WASM Artefakten (Portal/Wasm-Shell), wenn diese
+    nicht explizit benötigt werden.
+  * Erwartete Zeitersparnis: ca. 60-70% bei Desktop-fokussierten Builds.
+
+2. **Echte Gradle-Optimierung (Deep-Dive):**
+
+* **Configuration Cache:** Aktiviert (`org.gradle.configuration-cache=true`). Reduziert die Startzeit des Builds massiv,
+  besonders bei >80 Modulen.
+* **JVM Tuning:** Gradle-Heap auf 12GB erhöht, G1GC für bessere Latenz bei großen Objektheaps aktiviert, `Xshare:auto`
+  für schnelleren Start der JVM-Prozesse.
+* **Worker-Scaling:** Maximale Worker auf 12 erhöht (optimiert für 16-Kern Systeme des Users).
+* **Task-Filtering:** Statische Analysen (Detekt, Ktlint) und Dokka-Generierung werden nun nur noch ausgeführt, wenn sie
+  explizit angefordert werden (`-PrunStaticAnalysis=true`, `-PrunDokka=true`). Dies verhindert unnötige Last während der
+  normalen Entwicklung.
+
+3. **Conveyor Installations-Guide Fix:**
+  * `docs/02_Guides/Conveyor-Installation-Guide.md` wurde korrigiert.
+  * Der fehlerhafte GPG-Key-Download-Befehl (404 Error) wurde entfernt.
+  * Der Guide wurde auf die empfohlene Methode umgestellt: Direkter Download des `.deb`-Pakets für Ubuntu, welches das
+    Repository automatisch einrichtet.
+3. **Dokumentations-Update:**
+  * `Desktop-Packaging-Guide.md` um Sektion "Performance-Optimierung" erweitert.
+  * `MASTER_ROADMAP.md` aktualisiert.
+
+## ⚠️ Offene Punkte / Nächste Schritte
+
+* **WASM-Builds in CI:** Die CI-Pipeline muss sicherstellen, dass `-PenableWasm=true` gesetzt ist, um das Portal
+  weiterhin zu bauen.
+* **PoC Verifikation:** Die Verifikation auf physischer Hardware (Ubuntu 26.04) durch den User steht noch aus.
+
+---
+*Status: Änderungen erfolgreich angewendet. Verifikation der Performance-Steigerung durch User-Feedback ausstehend.*

+# System-Dokumentation: Simka Core Server
+
+## 1. Wer oder was ist Simka?
+**Simka** ist einer der beiden zentralen Pfeiler deiner hochperformanten, selbstgehosteten **Keller-Server-Landschaft** (neben dem zweiten Server *Zora*). Während Zora (dein Minisforum MS-R1 ARM64-Arbeitstier) primär für Core-Dienste und Datenhoheit zuständig ist, fungiert Simka als das eigentliche **Performance- und Rechenzentrum** im Keller.
+
+### Core-Spezifikationen & Hardware-Zustand (Stand: Mai 2026)
+* **Architektur:** x86_64 High-Performance Mini-PC / Server.
+* **Betriebssystem / Hypervisor:** **Proxmox VE 9.2** (aktuell auf Kernel/PVE-Stand 9.2.2).
+* **Kühlung & Wartung:** Frisch saniert im Mai 2026 mit **ARCTIC MX-7** Wärmeleitpaste auf der CPU und **ARCTIC TP-4** High-Performance Wärmeleitpads für optimale thermische Stabilität unter Volllast.
+* **Speichermedium:** Ultraschnelle NVMe-SSDs für die lokale Container- und VM-Ausführung.
+
+### Das anstehende "Monster-Upgrade" (Lieferung bis Ende der Woche)
+Simka wird in den nächsten Tagen hardwareseitig massiv aufgerüstet, um für lokale KI-Workloads und rechenintensive Pipelines bereitzuhoben:
+1.  **Arbeitsspeicher:** Erweiterung auf **64 GB DDR5 4800Mhz RAM** (maximale Kapazität für massives Multitasking und In-Memory-Datenbanken).
+2.  **Grafikkarte / GPU:** **PNY NVIDIA RTX 2000E Ada Generation**
+    * *Formfaktor:* Single-Slot & Low-Profile (perfekt für kompakte Servergehäuse, zieht Strom rein über den PCIe-Steckplatz).
+    * *Leistung:* Extrem energieeffiziente Ada-Lovelace-Architektur mit maximal **50W TDP** im Peak.
+    * *VRAM:* **16 GB Videospeicher mit ECC-Fehlerkorrektur** – das absolute Fundament für den ausfallsicheren 24/7-Betrieb von lokalen LLMs (Large Language Models).
+
+---
+
+## 2. Netzwerk-Konfiguration in der Keller-Landschaft
+
+Simka ist netzwerktechnisch perfekt redundant und isoliert aufgestellt. Die Kommunikation teilt sich auf zwei dedizierte Leitungen auf:
+
+```
+[ Erdgeschoss / Internet ]
+           │ (A1-Router / Fritzbox)
+           ▼
+     [ Keller-Switch ]
+       │          │
+       │ (10.0.0.20)
+       │          ▼
+       │     ┌───────────┐
+       │     │   ZORA    │◄──────┐
+       │     └───────────┘       │
+       │ (10.0.0.40)             │ Der exklusive
+       └──────►┌───────────┐     │ Keller-Highway
+               │   SIMKA   │     │ (192.168.99.X)
+               └───────────┘     │ Latenz: ~0.3 ms
+                     ▲           │
+                     └───────────┘
+```
+
+### A. Der primäre Uplink (`vmbr0`)
+* **Physisches Interface:** `nic0`
+* **Lokale IP:** `10.0.0.40/24`
+* **Gateway:** `10.0.0.138` (A1-Router / Fritzbox)
+* **Zweck:** Dieser Port verbindet Simka mit dem Hausnetzwerk und dem Internet. Über diesen Pfad greifst du via **Pangolin-Tunnel** (z. B. unter `https://fotos.mo-home.at`) sicher von außen (Remote von der Arbeit) auf deine Dienste zu.
+
+### B. Der exklusive "Keller-Highway" (`vmbr1`) – *Neu eingerichtet!*
+* **Physisches Interface:** `nic1` (Direktverbindung per Standard-Netzwerkkabel zu Zoras Interface `enp49s0`).
+* **Lokale IP:** `192.168.99.2/24`
+* **Gateway / DNS:** *Keines* (isoliertes Subnetz).
+* **Status:** Aktiviert mit **Autostart** bei Boot.
+* **Performance:** Saubere **0,33 ms Latenz** im Ping-Test, 0% Paketverlust.
+* **Zweck:** Blitzschnelle, vom restlichen Heimnetzwerk komplett isolierte Direktverbindung zwischen Zora und Simka. Hierüber laufen zukünftig automatisierte Backup-Pipelines, CI/CD-Prozesse und der interne Datenaustausch, ohne das normale LAN oder die Router-CPU zu belasten.
+
+---
+
+## 3. Container & Dienste: Wer läuft wo?
+
+Aktuell ist die Bereitstellung auf Simka modular und ressourceneffizient über Proxmox-Strukturen gelöst. Das Herzstück bildet die frisch migrierte Fotosammlung.
+
+### LXC-Container: `simka-immich`
+* **Umgebung:** `/opt/immich`
+* **Konfiguration:** Docker Compose Stack.
+* **Dienste im Stack:**
+    * `immich_server`: Das Hauptsystem der App (erreichbar lokal unter `http://10.0.0.40:2283`).
+    * `immich_machine_learning`: Zuständig für Objekterkennung und CLIP-Inferenz.
+    * `immich_postgres`: Die relationale Datenbank (PostgreSQL 14 mit `pgvector`/`vectorchord` Erweiterung).
+    * `immich_redis`: In-Memory-Datenstruktur-Store für Caching und Job-Queues.
+* **Daten-Zustand:**
+    * **Datenbank:** Erfolgreich importiert aus der `immich-db-backup.sql` (**610 MB** an Metadaten, Pfaden und Strukturen). Die alte, leere Auto-Datenbank wurde zuvor sauber via `dropdb` gelöscht.
+    * **Bilderpool:** Satte **~780 GB an Daten (131.578 Fotos/Videos)** liegen direkt lokal auf Simkas schneller NVMe-SSD.
+    * **Aktueller Betriebsmodus:** Reine **CPU-Ausführung** (x86_64). Die Mitternachts-Jobs und Worker-Anzahlen für Video-Transcoding sind CPU-schonend konfiguriert (max. 1–2 Worker), um den Server bis zum Wochenende nicht zu überlasten.
+    * **Zugriff:** Voll funktionsfähig lokal sowie mobil über die Android-App via Pangolin-Tunnel (Plattform-SSO wurde für den reibungslosen API-Sync der App deaktiviert).
+
+---
+
+## 4. Die Roadmap für das kommende Wochenende 🚀
+
+Sobald die Hardware geliefert wurde, wird Simka schrittweise zum KI-Kraftpaket ausgebaut:
+
+1.  **Hardware-Injektion:** Einbau der 64 GB DDR5 RAM und der NVIDIA RTX 2000E Ada.
+2.  **Die "Simka Core AI" VM:** Erstellung einer dedizierten virtuellen Maschine (z. B. Ubuntu/Fedora Server) in Proxmox.
+    * *PCIe-Passthrough:* Die RTX 2000E wird exklusiv direkt in diese KI-VM durchgereicht.
+    * *LLM-Infrastruktur:* Installation von **Ollama**. Dank der 16 GB ECC-VRAM laden wir dort mächtige Coding-Modelle wie `qwen2.5-coder:7b` (oder quantisierte 14b-Versionen) für blitzschnelle Code-Generierung in deiner IntelliJ-IDE auf deinem Ubuntu-Entwicklungs-PC.
+3.  **Immich-Beschleunigung:** Umstellung des `simka-immich` Docker-Stacks auf GPU-Inferenz. Die 88 Tensor-Kerne der RTX übernehmen dann die Gesichtserkennung und das Video-Transcoding in Millisekunden, wodurch die CPU komplett entlastet wird.
+4.  **CI/CD-Ausbau:** Migration des Gitea-Runners für dein Projekt **Meldestelle** aus der alten VM-Infrastruktur in einen schlanken, nativen LXC-Container auf Simka, der über den 0,3-ms-Highway direkt an dein Gitea auf Zora andockt.
+
+
+---
+
+## 5. Architektur- und Betriebs-Einschätzung (Ablage)
+
+🏗️ [Lead Architect]
+
+### Einschätzung der Architektur
+- Starker, sinnvoller Plattform-Split: Zora = Core/Control-Plane, Simka = Compute/Throughput. Das entspricht einer sauberen Trennung von „Authority“ und „Acceleration“ und passt zur Desktop-/Offline‑First Strategie der Meldestelle.
+- Netzwerk-Topologie mit dediziertem „Keller-Highway“ (vmbr1, 192.168.99.0/24) ist genau richtig für Replikation, CI/CD und Bulk-Daten. Minimiert Latenz/Jitter und entkoppelt vom Heimnetz.
+- Hardware-Entscheidung: RTX 2000E Ada (16 GB ECC, 50 W) ist ein hoch‑effizienter, 24/7‑tauglicher Inferenz‑Beschleuniger. Für LLMs bis 7B (FP16) und 14B (ggf. quantisiert) sowie NVENC/Transcoding ist sie sehr passend. Gegenüber „dickeren“ Karten (z. B. 4090/6000 Ada) verlierst du Peak‑Throughput, gewinnst aber Effizienz, Geräusch, thermische Stabilität und ECC.
+
+### Architektur-Empfehlungen (kurz & konkret)
+- Datenpfade klar trennen:
+  - „Hot“ AI/Transcode scratch auf lokaler NVMe (Simka)
+  - „Warm“ Artifacts/Backups via vmbr1 zu Zora
+- Standards definieren (Doku‑as‑Code):
+  - ADR: „GPU‑Passthrough für Compute‑VMs“ (Begründung, Alternativen, Trade‑offs)
+  - ADR: „LXC vs. VM für Runner/Builds“ (siehe DevOps‑Teil)
+- Observability als Querschnitt: Einheitliche Metrik‑Namen/Labels für Hosts, VMs, LXC (Node exporter/Nvidia exporter), damit Kapazitätsplanung reproduzierbar ist.
+
+---
+
+🐧 [DevOps Engineer]
+
+### Was ist gut gelaufen
+- Proxmox VE 9.2 auf aktuellem Stand, dedizierter LXC‑Stack für Immich, Ping‑Latenz ~0,33 ms auf vmbr1: sehr solide Grundlage.
+- Saubere Migration der Immich‑Datenbank und großer Medienpool lokal auf NVMe → I/O‑Bottlenecks minimiert.
+
+### Konkreter Wochenend‑Plan (Checkliste)
+1) Hardware‑Einbau und Firmware
+- RAM auf 64 GB einsetzen, Memtest (mind. 1 Pass) → Verifikation erforderlich.
+- GPU einsetzen; BIOS/UEFI:
+  - Primäre Anzeige auf iGPU/Onboard setzen (damit dGPU frei für Passthrough bleibt)
+  - Resizable BAR an (falls angeboten), SR‑IOV/IOMMU aktiv.
+
+2) Proxmox: NVIDIA GPU‑Passthrough für KI‑VM
+- Kernel/Boot: IOMMU aktivieren (`amd_iommu=on`), Neustart; prüfen, dass GPU in eigenem IOMMU‑Group landet.
+- Host: `vfio-pci` binden, Nouveau/NVIDIA‑Hosttreiber nicht laden (Host soll die GPU nicht claimen).
+- VM anlegen (Ubuntu Server LTS oder Fedora Server), PCIe‑Gerät hinzufügen (GPU + ggf. GPU‑Audio Function), MSI‑Interrupts aktivieren.
+- In‑Guest: NVIDIA Treiber + CUDA/CuDNN installieren; `nvidia-smi` muss die Karte stabil zeigen.
+
+3) „Simka Core AI“ VM: Modelle & Runtime
+- Ollama + optional OpenWebUI installieren.
+- Modelle (Beispiele mit 16 GB VRAM):
+  - qwen2.5‑coder:7b (FP16) oder 14b quantisiert (Q4_K_M/Q6_K)
+  - DeepSeek‑coder 6.7B, Llama‑3.1/3.2 8B Instruct quantisiert für Tools/Chat
+- Policies:
+  - Max. Parallelität und KV‑Cache Limits definieren, um OOM zu vermeiden.
+  - Watchdog/Service‑Unit für automatischen Neustart bei Treiber‑Resets.
+
+4) Immich auf GPU beschleunigen
+- Auf dem LXC‑Host NVIDIA Container Toolkit bereitstellen oder, falls LXC zu restriktiv ist: Immich in eine leichte VM oder in einen privilegierten LXC migrieren.
+- docker‑compose Anpassungen:
+  - `immich_machine_learning` mit `--gpus=all`/`runtime: nvidia`
+  - FFmpeg HWAccel aktivieren: `-hwaccel cuda -hwaccel_output_format cuda -c:v h264_nvenc/hevc_nvenc`
+  - Worker‑Limits neu justieren (mehr Transcode‑Jobs, wenn GPU an Bord)
+- Verifikation: Testtranscode und Embedding‑Job messen (Metriken/Logs sichern).
+
+5) Gitea Runner Migration (Meldestelle CI/CD)
+- Entscheidung: LXC vs. VM
+  - LXC (privileged, `nesting=1`, `keyctl=1`) ist ressourcenschonend, aber Docker‑in‑LXC erfordert Sorgfalt.
+  - Alternativ: kleine „Runner‑VM“ mit Docker – oft robuster bei komplexen Build‑Needs (z. B. Android/Compose Desktop Toolchains).
+- Netzwerk: Runner nutzt vmbr1, verbindet sich mit Gitea auf Zora, DNS via Hostfile/Static Route, kein Default‑GW nötig.
+- Caching: Maven/Gradle Cache persistent auf separatem Volume; Artefakt‑Upload über vmbr1.
+
+6) Netzwerk‑Feinschliff
+- vmbr1 ohne Gateway belassen; auf Hosts `metric`/Policy‑Routing setzen, damit Traffic für 192.168.99.0/24 strikt lokal bleibt.
+- Optional Jumbo Frames (MTU 9000) testen, wenn NICs/Switch/Direct‑Link es stabil können.
+- Proxmox‑Firewall:
+  - vmbr0 restriktiv (nur notwendige Ingress‑Ports)
+  - vmbr1 nur Host‑zu‑Host/Backup/CI erlauben
+
+7) Backup & Wiederherstellung
+- Immich: DB Dumps (pg_dump) + Objekt‑Speicher Sync via vmbr1 zu Zora (z. B. borg/restic/ZFS send‑recv).
+- Proxmox: regelmäßige VM/LXC Snapshots + Offhost‑Kopie.
+- Recovery‑Drills: 1x/Quartal Wiederherstellung in Test‑VM durchführen → „Verifikation ausstehend“ bis Log vorhanden.
+
+8) Observability & Betrieb
+- Node Exporter + NVIDIA DCGM/Exporter auf Simka; Prometheus/Grafana auf Zora aggregiert.
+- Alarme: NVMe Wear‑Level, GPU ECC Errors, Temp, OOM‑Kills, Docker/Container Restarts.
+- Energie: Optional `nvidia-smi -pl` Power‑Limit dokumentieren (wenn thermisch nötig), persistent via Systemd Unit.
+
+### Risiken/Watchouts
+- LXC + GPU ist möglich, aber distributions‑/kernel‑abhängig; wenn Treiber‑Bindung hakelt, früh auf VM umschwenken.
+- RTX 2000E hat 16 GB VRAM: bei mehreren gleichzeitigen LLM‑Sessions aggressiv quantisieren oder serielle Ausführung planen.
+- Pangolin‑Tunnel: Secrets/Token sicher hinterlegen und Rotation terminieren; 2FA erzwingen.
+
+---
+
+🧹 [Curator]
+
+### Dokumentations- und Abschluss‑Tasks
+- Dieses „Simka Core Server“ Dokument ist ein sehr guter Start. Ergänze bitte:
+  - Abschnitt „Verifikation/Beweise“ mit Links/Screenshots/Logs zu: Memtest, `nvidia-smi`, Immich‑GPU‑Transcode‑Probe, Ollama Inferenz‑Benchmark, CI‑Runner „connected“ Status.
+  - ADR‑Einträge unter `docs/01_Architecture/ADRs/`:
+    - ADR‑00X „Dedizierter Keller‑Highway (vmbr1) für Bulk/CI/Backup“
+    - ADR‑00X „GPU‑Passthrough für KI‑VM auf Proxmox“
+    - ADR‑00X „Runner: LXC (privileged) vs. kleine VM – Entscheidung & Gründe“
+  - Runbook „Simka Operations“: Boot‑Reihenfolge, Health‑Checks, Troubleshooting (GPU Reset, Treiber‑Reinstall, Container‑Restart).
+- Anti‑Halluzinations‑Protokoll anwenden:
+  - Kein „erledigt“ ohne Build/Test‑Beweis; markiere alle neuen Punkte als „Verifikation ausstehend“, bis Logs/Artefakte abgelegt sind.
+- Inventar & Versionen pflegen:
+  - BIOS/UEFI‑Version, Proxmox‑Kernel, NVIDIA‑Treiber, Docker Compose Hash, Immich Version, DB Schema Version.
