+## Infrastructure decisions
+- RustDesk is self-hosted on 172.27.40.3 — clients connect to local server not public relay
+- Netbird client management is on port 8443 via Caddy sidecar, NOT port 443
+- Headscale v0.28: all write operations require numeric user ID, not username
+- Tailscale on Windows overrides DNS — disconnect before testing split DNS changes
+- Servers running Tailscale must run `sudo tailscale set --accept-dns=false` before joining Netbird
+
+## Agent OS build state
+- Phase 1-2 (file structure + NFS + identity interview): not yet started
+- First skill to build: infra-monitor (Docker health + agent watchdog)
+- Notifications target: Home Assistant at 172.27.10.6
