# Persistent Memory

Facts that don't expire. If you'd have to re-explain it to a new agent every time, it belongs here.

## Infrastructure decisions
- RustDesk is self-hosted on 172.27.40.3 — clients connect to local server not public relay
- Netbird signal+management both route through NPM on port 443 — exposedAddress in /opt/stacks/netbird/config.yaml must be https://netbird.nxm.co.za:443 (caddy-netbird on :8443 exists but is not used externally)
- 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
