Development record

abcd's dashboard reaches other devices only through Tailscale: it listens on the computer's Tailscale addresses and admits a device only when Tailscale's own lookup names it. The product thinker wants WireGuard as a built-in alternative the person may choose instead, so the dashboard does not depend on one vendor's account and coordination service. A plain WireGuard tunnel has no lookup that names a person's device, so the alternative needs its own device identity, such as each peer's public key mapped to a named device.
