Roll the verified Option-B per-app oauth2-proxy sidecar out to the remaining four forward-auth apps after the pihole canary was confirmed fail-closed (unauthenticated -> 302 to Keycloak, pod 2/2, clean sidecar OIDC discovery). Each app's Gateway route now terminates at its oauth2-proxy sidecar (:4180, --allowed-group=media-users, --upstream=http://127.0.0.1:<uiport>); the gateway-ingress CiliumNetworkPolicy allows the Gateway to reach ONLY :4180, so the bare UI is never served un-authenticated (fail-closed; R-IDP-02/06). The apps' own app/API ports stay in-Service for EAST-WEST callers (arr -> qbittorrent:8080 / jackett:9117) via the existing reciprocal-ingress allows. - keycloak: confidential jackett/qbittorrent/radarr/sonarr clients (realm-import + realm-clients mirror), provisioned live via kcadm (groups membership mapper). - secrets: four SOPS/age <app>-oauth2-proxy-credentials, wired into apps/wave-0 and apps/wave-1 by the renderer's sidecar-creds wave rule. - ci: remove the temporary canary deferral (all five goldens now reproduce).
