Restructure docs: archive VLAN migration, update IPs to VLAN 10

Major documentation cleanup after VLAN migration completion:
- Archive 12 VLAN project docs to archive/vlan-migration/
- Archive 5 done WIP docs (VLAN proposals, AI stack, Fossorial, DNS backup)
- Create standing reference docs 08-DNS-ARCHITECTURE and 09-TAILSCALE-VPN
- Renumber docs to clean 01-09 sequence with merged CHANGELOG
- Update all active docs from stale 192.168.31.x to current VLAN 10 IPs
- Fix CSS1 (.10.9→.10.3) and ZX1 (.10.7→.10.4) IPs in hardware inventory
- Clean 06-VLAN-DEVICE-ASSIGNMENT: remove migration columns/sections, fix VLAN 25 subnet

+# Local AI Stack on Unraid
+
+**Status:** ✅ Deployed  
+**Last Updated:** 2026-01-26
+
+---
+
+## Current Deployment
+
+| Component | Status | URL/Port |
+|-----------|--------|----------|
+| Ollama | ✅ Running | http://192.168.31.2:11434 |
+| Open WebUI | ✅ Running | http://192.168.31.2:3080 |
+| Intel GPU | ✅ Enabled | /dev/dri passthrough |
+
+### Models Installed
+
+| Model | Size | Type |
+|-------|------|------|
+| qwen2.5-coder:7b | 4.7 GB | Base coding LLM |
+| unraid-assistant | 4.7 GB | Custom model with infrastructure knowledge |
+
+---
+
+## Custom Model: unraid-assistant
+
+A fine-tuned system prompt model that knows the xtrm-lab.org infrastructure:
+
+### Knowledge Included
+- **Network topology**: All VLANs (10,20,25,30,31,35,40,50), IPs, gateways
+- **45+ Docker containers**: Names, images, ports, purposes
+- **RouterOS 7**: Commands, VLAN patterns, firewall rules
+- **Traefik**: Labels, routing, SSL configuration
+- **Authentik**: SSO middleware, provider setup
+- **External URLs**: All xtrm-lab.org services
+
+### Usage
+
+```bash
+# Terminal (SSH to Unraid)
+ai "How do I add a device to the IoT VLAN?"
+ai "What port is gitea running on?"
+ai "Show me Traefik labels for a new app with Authentik"
+
+# Interactive mode
+ai
+```
+
+### Rebuild Model
+
+If infrastructure changes, update and rebuild:
+
+```bash
+# Edit the Modelfile
+nano /mnt/user/appdata/ollama/Modelfile-unraid
+
+# Rebuild
+docker exec ollama ollama create unraid-assistant -f /root/.ollama/Modelfile-unraid
+```
+

+
+## Hardware
+
+| Component | Spec |
+|-----------|------|
+| CPU | Intel N100 (4 cores) |
+| RAM | 16GB (shared with Docker) |
+| GPU | Intel UHD (iGPU via /dev/dri) |
+| Storage | 1.7TB free on array |
+
+### Performance
+- ~1 token/sec with 7B models
+- Responses take 30-90 seconds
+- Suitable for occasional use, not real-time chat
+

+
+## Containers Stopped for RAM
+
+To free ~4.8GB for AI workloads:
+
+| Container | RAM Freed | Purpose |
+|-----------|-----------|---------|
+| karakeep | 1.68 GB | Bookmark manager |
+| unimus | 1.62 GB | Network backup |
+| homarr | 686 MB | Dashboard |
+| netdisco-web | 531 MB | Network discovery UI |
+| netdisco-backend | 291 MB | Network discovery |
+
+To restart if needed:
+```bash
+docker start karakeep unimus homarr netdisco-web netdisco-backend
+```
+
+---
+
+## Docker Configuration
+
+### Ollama
+```bash
+docker run -d \
+  --name ollama \
+  --restart unless-stopped \
+  --device /dev/dri \
+  -v /mnt/user/appdata/ollama:/root/.ollama \
+  -p 11434:11434 \
+  ollama/ollama
+```
+
+### Open WebUI
+```bash
+docker run -d \
+  --name open-webui \
+  --restart unless-stopped \
+  -p 3080:8080 \
+  -e OLLAMA_BASE_URL=http://192.168.31.2:11434 \
+  -v /mnt/user/appdata/open-webui:/app/backend/data \
+  ghcr.io/open-webui/open-webui:main
+```
+
+### AI Command Helper
+```bash
+# /usr/local/bin/ai
+#\!/bin/bash
+MODEL="unraid-assistant"
+if [ $# -eq 0 ]; then
+    docker exec -it ollama ollama run $MODEL
+else
+    docker exec ollama ollama run $MODEL "$*"
+fi
+```

+
+## Open WebUI RAG Setup
+
+For detailed documentation beyond system prompt:
+
+1. Go to http://192.168.31.2:3080
+2. **Workspace** → **Knowledge** → **+ Create**
+3. Name: `Infrastructure`
+4. Upload docs from `/mnt/user/appdata/open-webui/docs/`
+
+Infrastructure docs are pre-copied to that location.

+## Future: N5 Air (Ryzen AI 5 255) Upgrade
+
+Planning to migrate AI stack to N5 Air with Ryzen AI 5 255:
+
+| Metric | N100 (current) | Ryzen AI 5 255 |
+|--------|----------------|--------------|
+| Speed | ~1 tok/s | ~5-8 tok/s |
+| Max model | 7B | 14B-32B |
+| Response time | 30-90s | 5-15s |
+
+Features XDNA NPU (16 TOPS) for potential AI acceleration. DDR5 + 6c/12t CPU will significantly improve inference.
