The Ports page showed no service selected for Stoat, and the app's URL
never appeared anywhere, so there was no way to learn which port it is
on.
Field 1 of a PORT descriptor is the parent SERVICE:
db_list_installed_app matches it against each compose service name to
attach the app's access URL. Stoat named containers instead —
"stoat-caddy" and "stoat-livekit", whose services are "caddy" and
"livekit". It is the only app in the catalogue that did; rocketchat says
rocketchat-service, matrix says matrix-synapse, and both are real
service names. Nothing matched, so no URL was ever associated and the
Ports page had nothing to select.
The port itself was always allocated correctly — Caddy publishes 4210 —
which is why the app worked for anyone who already knew the number.
The live config had also lost the 11th field (the Traefik subdomain,
"stoat") that the template carries, so restore that at the same time.
Not a Caddy problem: Stoat's Caddy is its internal path router, doing
prefix stripping and Location rewrites across api, events, autumn,
january, gifbox and web plus file-serving /.well-known/stoat. Traefik is
the edge in front of it — the same split Nextcloud uses with its nginx
sidecar — and Traefik cannot serve that .well-known file at all.
