+## Fred's Homelab Infrastructure
+
+### Network
+- Main Network: 10.0.10.0/24
+- VPN: WireGuard tunnel at 10.0.8.0/24
+- VPS: 66.63.182.168 (vps.nianticbooks.com) running Caddy reverse proxy
+
+### Proxmox Hosts
+- Main Proxmox host: 10.0.10.3 (main-pve)
+- HP DL380: Proxmox host running my container
+
+### Key Services (LXC Containers)
+- Home Assistant: 10.0.10.24 - Smart home automation
+- n8n: 10.0.10.22 (CT 106) - Workflow automation
+- Uptime Kuma: 10.0.10.26 (CT 128) - Service monitoring
+- OpenClaw Gateway: 10.0.10.28 (CT 130) - AI agent coordination (that's me!)
+  - Running as LXC container on HP DL380
+  - No sound card/audio output on this container
+- Step-CA: 10.0.10.15 (CT 115) - Internal certificate authority
+
+### Paired Nodes
+- **Fred's iMac**: 10.0.10.11 - OpenClaw desktop app node
+  - Provides: Camera, screen recording, canvas display, notifications
+  - Potential audio output for TTS
+  - Near Fred but screen visibility limited
+  - **Known Issue:** `nodes screen_record` fails with "The operation could not be completed" (OpenClaw 2026.2.1 bug)
+  - **Workaround:** Use native `screencapture` command instead:
+    ```bash
+    # Record 3 seconds of screen
+    screencapture -T 3 -V 3 /tmp/screen-recording.mp4
+    ```
+
+### Current Projects
