+# Complete Infrastructure Audit Report
+## Fred Book's Homelab - February 5, 2026
+
+**Audited by:** Funky (OpenClaw Agent) + Claude Code (previous audit)  
+**Audit Period:** January 2026 - February 5, 2026  
+**Last Updated:** 2026-02-05 15:24 UTC
+

+
+## Executive Summary
+
+Fred's homelab is a well-structured Proxmox-based infrastructure supporting smart home automation, workflow automation, monitoring, and emerging 3D printing business operations. The system demonstrates good security practices (internal CA, VPN) and automation (n8n workflows, monitoring).
+
+**Key Strengths:**
+- ✅ Multiple Proxmox hosts providing redundancy
+- ✅ Internal certificate authority (Step-CA)
+- ✅ WireGuard VPN for secure remote access
+- ✅ Comprehensive monitoring (Uptime Kuma, n8n workflows)
+- ✅ External reverse proxy (Caddy on VPS)
+
+**Areas for Improvement:**
+- ⚠️ Backup system needs documentation and verification
+- ⚠️ SSH connectivity issues between some containers
+- ⚠️ No centralized infrastructure documentation (Gitea needed)
+- ⚠️ 4TB HDD on router-pve underutilized
+
+---

+## Known Issues
+
+### Critical Issues
+None currently
+
+### Important Issues
+
+**1. SSH Connectivity: OpenClaw → router-pve**
+- **Symptom:** SSH connections hang/timeout
+- **Affected:** OpenClaw container (10.0.10.28) cannot SSH to router-pve (10.0.10.2)
+- **Workarounds:** Fred can SSH from Windows, key is properly installed
+- **Impact:** Medium (workarounds available)
+- **Next Steps:** Investigate network routing, check firewall rules
+
+**2. Backup System Documentation**
+- **Symptom:** Backup verification workflow exists but details unclear
+- **Impact:** Medium (backups might be working, just not documented)
+- **Next Steps:** Inventory backup jobs, test restores
+
+**3. 4TB HDD on router-pve Underutilized**
+- **Symptom:** Large storage capacity sitting idle
+- **Impact:** Low (opportunity cost, not a failure)
+- **Next Steps:** Format/mount if needed, configure as backup target
+
+### Minor Issues
+
+**4. Node Screen Recording (Fred's iMac)**
+- **Symptom:** `nodes screen_record` fails on OpenClaw 2026.2.1
+- **Workaround:** Use native `screencapture` command
+- **Impact:** Low (workaround available)
+- **Status:** Known OpenClaw bug
+
+**5. BlueBubbles Delivery Failures**
+- **Symptom:** Morning brief cannot deliver via BlueBubbles (iMac 10.0.10.11:1234)
+- **Impact:** Low (can read briefs from files)
+- **Notes:** iMac may be offline/sleeping, or BlueBubbles server not running
+
+---
+
+## Resource Utilization
+
+**Needs Assessment:**
+- router-pve: **Underutilized** (only running Home Assistant)
+  - Good candidate for: Gitea, PBS, Pi-hole, Vaultwarden
+  - 4TB HDD available for backups
+- main-pve: Likely well-utilized with multiple containers
+- pve-storage: Storage-focused, appropriate load
+- HP DL380: Running OpenClaw, room for more?
+
+**Power Consumption:**
+- Older servers (HP DL380) likely draw 100+ watts
+- Mini PC approach would reduce power (20-50W)
+- Consider consolidation if power cost is concern
+
+---
+
+## Security Assessment
+
+### Strengths ✅
+- Internal CA (Step-CA) for service certificates
+- WireGuard VPN for secure remote access
+- Separation of internal and external certificates
+- External reverse proxy isolates homelab from internet
+- SSH key authentication in use
+
+### Recommendations 🔒
+- Document firewall rules
+- Regular security updates (automate with `unattended-upgrades`)
+- Consider fail2ban for SSH brute-force protection
+- Audit user accounts and permissions
+- Regular review of exposed services
+- Consider network segmentation (VLANs) for business services
+
+---
+
+## Compliance & Best Practices
+
+### Documentation ✅ In Progress
+- Infrastructure audit (this document)
+- Obsidian vault for technical docs
+- Gitea deployment planned for version control
+
+### Backup & Recovery ⚠️ Needs Work
+- Backup verification exists but needs documentation
+- No documented restore procedures
+- No tested restore (as far as we know)
+- 3-2-1 rule partially implemented (need offsite backup)
+
+### Monitoring ✅ Good
+- Uptime Kuma monitoring services
+- n8n workflows for alerting
+- Multiple notification channels (Discord, Email, Pushover)
+
+### Change Management ⚠️ Needs Improvement
+- No formal change tracking
+- Gitea will help with this
+- Recommend tagging infrastructure changes with `#infrastructure` `#business`
+
+---
+
+## Budget & Hardware Considerations
+
+### Existing Hardware
+- 3+ Proxmox hosts (good)
+- HP DL380 (enterprise-grade but power-hungry)
+- 4TB HDD on router-pve (good for backups)
+- OMV storage servers (functional)
+
+### Planned Hardware
+- GPU for 3D printing VM (budget: $200-300)
+  - RTX 3060 recommended
+  - Need to verify PCIe slot availability
+
+### 2026 Trends
+- Mini PCs: Ryzen-based, 32-64GB RAM, 20-50W power draw
+- NVMe storage: Prices stable
+- RAM: Expensive in late 2025/2026
+- GPUs: Prices normalized after crypto crash
+
+---
+
+## Lessons Learned & Best Practices
+
+### What's Working Well
+1. **Separation of concerns**: Internal CA + External LetsEncrypt
+2. **VPN-first approach**: Secure remote access without exposing services
+3. **Monitoring**: Uptime Kuma + n8n provides good visibility
+4. **Automation**: n8n workflows automate repetitive tasks
+
+### What Needs Improvement
+1. **Documentation**: Scattered, needs centralization (Gitea will help)
+2. **Backup testing**: Backups exist but restore procedures untested
+3. **Resource utilization**: router-pve and 4TB HDD underused
+4. **Change tracking**: No formal process for documenting infrastructure changes
+
+### Recommendations for Future
+1. **Infrastructure as Code**: Use Terraform or Ansible for reproducibility
+2. **Gitea**: Single source of truth for infrastructure knowledge
+3. **Regular Audits**: Quarterly infrastructure reviews
+4. **Capacity Planning**: Monitor growth trends, plan upgrades proactively
+
+---
+
+## AI Agent Access & Integration
+
+### Current Integration
+- OpenClaw Gateway (10.0.10.28) has access to:
+  - ✅ n8n API (workflow triggering, status checks)
+  - ✅ Uptime Kuma data (via n8n webhooks)
+  - ✅ Apple Calendar/Reminders (CalDAV)
+  - ✅ TOOLS.md (local infrastructure notes)
+  - ⏳ Gitea (planned - will serve as knowledge base)
+
+### Planned Integration
+- **Gitea as Source of Truth**:
+  - AI agents can read infrastructure docs
+  - Search for configurations
+  - Update documentation automatically
+  - Query printer profiles, Docker Compose files, scripts
+
+- **Example Use Cases**:
+  - "What port does Home Assistant run on?" → Query Gitea infrastructure/service-inventory.md
+  - "What's the Bambu A1 nozzle temp for PLA?" → Query 3d-print-farm/printer-profiles/bambu-a1.ini
+  - "Show me the n8n backup workflow" → Query homelab-repo/docker-compose/n8n.yml
+
+### Agent Capabilities
+- **Read**: Configuration files, documentation, scripts
+- **Search**: Git history, grep for specific settings
+- **Update**: Commit documentation changes
+- **Notify**: Alert Fred to infrastructure changes or issues

+# Homelab 2026 Starter Stack + 3D Printing GPU Passthrough
+
+**Research compiled for Fred's homelab and 3D print farm business**
+
+*Source: VirtualizationHowTo.com + Reddit r/Proxmox community*
+
+---
+
+## 🎯 Why This Matters for You
+
+**Your situation:**
+- Already running Proxmox (10.0.10.3, 10.0.10.2, 10.0.10.4)
+- Planning 3D print farm business with your son
+- Need CAD/slicing software for 3D printing
+- Want modern, efficient homelab stack
+
+**What you'll learn:**
+1. **2026 best practices** for homelab hardware and software
+2. **GPU passthrough** to run Windows VM with CAD software (Fusion 360, PrusaSlicer, etc.)
+3. **How this fits your 3D print farm** business needs
+
+---
+
+## Part 1: Ultimate Homelab Stack for 2026
+
+### Hardware Recommendations
+
+**The Modern Mini PC Approach** (you already have Proxmox servers, but good to know for expansion):
+
+**Ideal Specs:**
+- **CPU:** Ryzen 7 or Ryzen 9 (uniform, efficient)
+- **RAM:** 32-64GB DDR5 (sweet spot despite high 2025/2026 prices)
+- **Storage:** Two NVMe drives (mirrored or separate workloads)
+- **Network:** 2.5Gb or 10Gb
+- **Power draw:** 20-50 watts (vs. your older servers drawing 100+ watts idle)
+
+**Why mini PCs are trending:**
+- Quiet, compact, efficient
+- Enterprise-grade performance
+- Great models: Minisforum MS-A2, MS-02, MS-01; Beelink SER9 Max
+
+**Your setup:** You already have Proxmox hosts, but this is good to know if you want to add a dedicated node for 3D printing/CAD work later.
+
+---
+
+### Software Stack - The 2026 Essentials
+
+#### 1. **Proxmox VE 9.1** (Foundation) ✅ You already have this!
+
+**What's new in 9.1:**
+- **OCI container image support** (NEW) - More efficient than traditional containers
+- **vTPM support** for VMs
+- **Better SDN (software-defined networking)**
+- **Improved backup features**
+- No license shenanigans
+- Huge community, tons of scripts
+
+**Why it's still #1:** Best balance of power and simplicity for home labs
+
+---
+
+#### 2. **Container Management: Komodo or Portainer**
+
+**Komodo** (New kid on the block - 2025/2026 favorite):
+- **Free and fast**
+- Modern UI
+- Easy Docker deployment and monitoring
+- Lighter weight than Portainer
+- Perfect for your n8n + container stack
+
+**Portainer** (The 800lb gorilla):
+- More features, more complex
+- GitOps built-in
+- Like "VMware vCenter for containers"
+- You already know Docker/containers, so either works
+
+**Recommendation for you:** Try Komodo - it's simpler and you said n8n node definitions are problematic. Komodo might be easier.
+
+---
+
+#### 3. **Nginx Proxy Manager** (Reverse Proxy) ✅ You should add this!
+
+**Why you need this:**
+- Manages all your services behind one IP
+- **Auto LetsEncrypt SSL certificates** (no more manual cert renewals!)
+- GUI-based (way easier than editing Nginx configs)
+- Perfect for exposing services safely
+
+**What it does:**
+- HTTPS termination
+- Automatic renewals
+- Domain/subdomain routing (homeassistant.nianticbooks.com, n8n.nianticbooks.com, etc.)
+- Access lists and authentication
+- Organizes internal vs external access
+
+**Your use case:**
+- Right now you probably access services by IP:port (10.0.10.24:8123, etc.)
+- With NPM: nice URLs (homeassistant.local or via your Caddy VPS)
+- Combined with your Caddy VPS = secure remote access to everything
+
+---
+
+#### 4. **Gitea** (Self-hosted Git) - You need this!
+
+**Why:**
+- Store your Docker Compose files in Git (you said you lose track of configs)
+- Version control for infrastructure
+- Backup your n8n workflows as code
+- Store 3D printing business documentation
+
+**Lightweight and fast:**
+- Runs as a container
+- Looks like GitHub
+- Supports issues, pull requests, branches
+- **Gitea Actions** = CI/CD built-in (run automation on git push)
+
+**Your use case:**
+- Store Obsidian vault in Gitea (private repo on your network)
+- Document infrastructure changes
+- Track 3D print farm business code (if you automate anything)
+
+---
+
+#### 5. **Proxmox Backup Server (PBS)** ✅ Critical!
+
+**You need this running ASAP:**
+- Free, from Proxmox team
+- Deduplication, compression, incremental backups
+- Fast restores
+- Can run on same host (separate disk) or dedicated mini PC/NAS
+
+**Your setup idea:**
+- Install PBS on one of your Proxmox nodes
+- Point to OMV storage (10.0.10.5) for backup target
+- Schedule automated backups of all VMs/containers
+- **INCLUDES backing up your OpenClaw container!**
+
+**3-2-1-1-0 rule:**
+- 3 copies of data
+- 2 different media
+- 1 offsite (your VPS? Backblaze B2?)
+- 1 offline (USB drive, fireproof safe)
+- **0 errors** after verification ← Most important!
+
+---
+
+#### 6. **Core Containers to Run**
+
+**From the "15 containers that make home lab better" list, here's the essentials:**
+
+**Monitoring & Logging:**
+- **Dozzle** - Real-time container log viewer (one screen, all logs)
+- **Netdata** - System monitoring (CPU, RAM, disk, network)
+- **Uptime Kuma** ✅ You already have this (10.0.10.26)
+
+**Management:**
+- **Komodo** - Container stack management
+- **Nginx Proxy Manager** - Reverse proxy with SSL
+- **Gitea** - Git repository
+
+**Security & Services:**
+- **Vaultwarden** ✅ You already planned this (10.0.10.27 Week 1)
+- **Pi-hole** - DNS-level ad blocking (also planned)
+- **Mailrise** - Unified notification bridge (emails become push notifications)
+
+**Automation:**
+- **n8n** ✅ You already have this (10.0.10.22)
+

+
+## Part 2: GPU Passthrough for 3D Printing Lab
+
+### The Use Case (From Reddit)
+
+**What someone built:**
+- Proxmox host
+- Windows 10 VM with GPU passthrough
+- GPU: NVIDIA card (prices dropped in late 2024/2025)
+- Purpose: Run CAD software (Fusion 360, SolidWorks, etc.) and slicing software (PrusaSlicer, Cura, etc.)
+
+**Why GPU passthrough matters:**
+- CAD software needs GPU acceleration
+- 3D rendering and complex models
+- Slicing large files with previews
+- Remote access to Windows VM = access CAD from anywhere
+
+---
+
+### How It Works
+
+**The Setup:**
+1. **Proxmox host** with dedicated GPU (not the iGPU used for Proxmox console)
+2. **Windows 10/11 VM** with GPU passed through
+3. **RDP or remote desktop** to access VM
+4. Install CAD software, slicers, 3D printing tools
+5. Access from any device (your PC, iPhone, Mac)
+
+**The Result:**
+- Full GPU acceleration for CAD
+- Can run multiple 3D printing tools
+- Centralized 3D printing workstation
+- Your son can access the VM too (collaborative design work)
+
+---
+
+### Requirements
+
+**Hardware:**
+- Dedicated GPU (NVIDIA or AMD)
+  - Don't use iGPU (Proxmox needs it for console)
+  - Budget options: GTX 1060, 1660, RTX 3060
+  - Pro options: RTX 4060, 4070 (better CAD performance)
+- CPU with VT-d / AMD-Vi (virtualization extensions) ✅ Your Ryzen CPUs support this
+- Motherboard with IOMMU support ✅ Your Proxmox hosts likely support this
+
+**Software:**
+- Proxmox with IOMMU enabled in BIOS
+- GPU drivers inside Windows VM
+- Remote desktop software (built-in RDP or Parsec for better performance)
+
+---
+
+### Configuration Steps (High-Level)
+
+**1. Enable IOMMU in BIOS:**
+- Boot into BIOS on Proxmox host
+- Enable VT-d (Intel) or AMD-Vi (AMD)
+- Save and reboot
+
+**2. Enable IOMMU in Proxmox:**
+Edit `/etc/default/grub`:
+```bash
+# For Intel
+GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
+
+# For AMD
+GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt"
+```
+
+Update grub: `update-grub && reboot`
+
+**3. Load VFIO modules:**
+Edit `/etc/modules`:
+```
+vfio
+vfio_iommu_type1
+vfio_pci
+vfio_virqfd
+```
+
+**4. Blacklist GPU drivers on host:**
+(So Proxmox doesn't try to use the GPU)
+```bash
+echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
+echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf
+update-initramfs -u
+```
+
+**5. Create Windows VM in Proxmox:**
+- Machine: q35
+- BIOS: OVMF (UEFI)
+- Add EFI disk
+- **Add PCI device** (your GPU)
+- Set CPU type to "host" (important for passthrough)
+- Enable "PCIe" checkbox on GPU device
+
+**6. Install Windows + GPU drivers:**
+- Install Windows normally
+- Install NVIDIA/AMD drivers inside Windows
+- Verify GPU is recognized (Device Manager)
+
+**7. Remote Access:**
+- Enable RDP in Windows
+- Or install Parsec (better for CAD/gaming performance)
+- Access VM from anywhere on your network
+
+---
+
+### For Your 3D Print Farm Business
+
+**Use cases:**
+1. **Centralized CAD workstation** - You and your son access same VM
+2. **Slicing station** - Queue up print jobs, generate G-code
+3. **Design library** - Store all STL files, designs in one place
+4. **Remote access** - Work on designs from your bus route (when parked, obviously!)
+5. **Backup everything** - VM backups = CAD software + settings + files all backed up together
+
+**Software you'd run:**
+- **Fusion 360** (free for hobbyists/small business)
+- **PrusaSlicer** or **Cura** (slicing)
+- **Blender** (if doing custom modeling)
+- **Bambu Studio** (for your Bambu A1)
+- **OctoPrint / Mainsail** web UIs (manage printers remotely)
+
+**Workflow:**
+1. Design in Fusion 360 (with GPU acceleration)
+2. Export STL
+3. Slice in PrusaSlicer/Bambu Studio
+4. Send to printer (via OctoPrint or direct USB)
+5. Monitor prints via webcam + OctoPrint
+
+---
+
+### Budget GPU Options (2026 Prices)
+
+**Entry Level ($150-250 used):**
+- GTX 1060 6GB - Good for basic CAD
+- GTX 1660 Super - Better performance, still affordable
+
+**Mid-Range ($250-400):**
+- RTX 3060 12GB - Excellent CAD performance, good value
+- RTX 4060 - Newer, more efficient
+
+**Pro Level ($500+):**
+- RTX 4070 - Great for complex CAD assemblies
+- RTX 4080 - Overkill for most home use
+
+**Recommendation for you:** RTX 3060 or RTX 4060 - sweet spot for price/performance for CAD work.
+
+---
+
+## How This Fits Your Current Setup
