Three apps were instanceable and the rest were silent, so the feature
looked far narrower than it is. Every app has now been checked against
the two rules instance_create.sh enforces, and the answer recorded in
its config rather than left unset.
32 apps are instance-safe and now say so. Six are not, and each says why
in its own words instead of being indistinguishable from an app nobody
had reviewed:
pihole a DNS server must own port 53
unbound a resolver must own its fixed 5335
stalwart a mail server must own 25/465/587/993
traefik must own 443, and one Traefik routes every other app
prometheus node-exporter and cadvisor carry no "prometheus" prefix
stoat pins 7881, and database/redis/rabbit/minio carry no prefix
The first four are genuinely one-per-host: the port is not arbitrary, it
is the protocol. The last two are compose-identity problems and could be
fixed by prefixing those service names, which is a change to make
deliberately rather than in passing.
Recorded as an explicit false with a reason, not left unset, so the next
person reads a decision instead of an absence. The audit was verified not
to pass anything vacuously: every app resolves at least one service name,
so no app reached "eligible" merely because nothing was found to check.
