The #34 rename dropped the legacy chat/triage names from the certificate
SANs, the hermes-sites Ingress, the CoreDNS overrides and the Keycloak
ensure script at the same time, so nothing failed loudly: DNS and TLS
still looked healthy while the legacy hosts served 404 and the renamed
hosts could not finish a login.
Pin the invariant that makes that silent: a public host is either served
by all four layers or by none. The table of hosts is the contract, so
retiring a name stays a deliberate edit rather than a side effect.
Verified to catch the regression: against the pre-fix tree these fail for
both legacy hosts on all four layers (9 failures); against this branch
the suite is green.
