The DigitalOcean backend droplet (was bare ssh alias lilith-store-backend,
209.38.51.98) joins wg1 at 10.9.0.5 as a first-class cloud-class member —
runs quinn.api INTERNAL, the MCP gateways, DO Managed PG access, and private
workers (general backend node, not MCP-only). The .5 slot was held by
strawberry (Quinn's iPhone), which never worked reliably and is now off the
mesh; re-enrollable later via wg-phone-add. public=null so host-apply renders
the wg path (private node, no public app ports; reached via ProxyJump yuzu).
