Add a public front door for the WatchState admin UI on watchstate.unkin.net via the external (DMZ) Traefik, alongside the existing internal watchstate.k8s.syd1.au.unkin.net gateway. oauth2-proxy fronts both hostnames. - DNSRecord watchstate-dns-internal (bind-internal/authoritative, unkin.net zone) -> A 198.18.199.0, the traefik-external VIP (arrstack precedent). - watchstate-external Gateway (traefik-external) + HTTPRoutes: http->https redirect and https -> watchstate-oauth2:80. TLS terminated with the Let's Encrypt *.unkin.net wildcard (wildcard-unkin-net-tls), so no cert-manager/external-dns annotations. - oauth2-proxy: relative redirect-url (/oauth2/callback) so reverse-proxy mode derives scheme+host per request, making the callback work on BOTH hosts; cookie + whitelist domains cover both hostnames. - Drop the no-op sync-wave: "0" annotation on the vaultauth default VaultAuth. Dependencies: - wildcard-unkin-net-tls reflection into the watchstate namespace (reflector allow-list, argocd-apps PR #418). - Both callback URIs registered on the Authentik watchstate provider (terraform-authentik, separate PR).
