I tightened HERMES_WEBUI_HOST to 127.0.0.1 on the reasoning that the compose
service had published loopback and the unit had widened it. That reasoning
missed the consumer: this unit is host-networked (it shares the CDP daemon's
loopback), so Caddy cannot reach it by container name and fronts the guarded
vhost hermes.franksdank.cloud with `reverse_proxy 192.168.0.143:8787` — recorded
in dankclaw/Caddyfile with the same explanation. With the app on loopback that
upstream is dead, so the vhost broke.
The wildcard bind is what serves BOTH consumers: Caddy on the LAN address and
the phone's SSH tunnel on the host's localhost. Controls are the auth chain in
front of the vhost plus the webui password. The unit comment now states this
instead of the incorrect 'as before' claim, and the near-miss is worth the
paragraph: the e2e gate stayed green because no spec covers that vhost.
