- Assign static IPs to all 13 containers (172.20.0.2–13) so DNS zone records match actual container IPs regardless of start order. - Update cell.zone: all .cell domains now point to cell-caddy (172.20.0.2) which is the correct single entry point via Caddy reverse proxy. - Create config/radicale/config so the calendar container actually starts. - Fix webdav: replace empty users.passwd with USERNAME/PASSWORD env vars. - Fix DNS fallback IP in wireguard_manager: 172.20.0.2→172.20.0.3 (cell-dns). - Remove duplicate http://ui.cell from Caddyfile. - Add persistent data volumes for rainloop and filegator. - Fix mail domainname placeholder (yourdomain.com→cell.local).
