Record the operator's 2026-11-08 decision to move public HTTP(S) ingress
from edge port-forwarding of 80/443 to an outbound-only Cloudflare Tunnel
(in-cluster cloudflared, proxied CNAMEs via ExternalDNS). Motivation: the
GFiber router cannot hairpin NAT and advertises Google IPv6 DNS via RA, so
LAN clients bypass Pi-hole split horizon and fail.
Docs 00/01/03/07/08/09/13/14, GLOSSARY and definition-of-done brought into
line. R-DNS-01..03 and R-TLS-01..03 wording unchanged. New requirements:
R-DNS-04 (no 80/443 forward, resolver-independent LAN reachability),
R-DNS-05 (only `public` services at the tunnel; 404 catch-all; no public
record for `internal`), R-SEC-04 (Kubernetes API never publicly reachable).

New identity subsystem, and resolves the C2 auth open question:
- docs/15-identity-and-access.md + ADR-0014: Keycloak as central IdP; native
OIDC where supported (Gitea, Nextcloud, Grafana, Kasm, Semaphore, Headlamp)
and oauth2-proxy forward-auth for bare UIs (PiHole, *arr, qBittorrent,
Homepage, Prometheus, Alertmanager, Hubble). Group-based authz + MFA;
declarative realm/clients (GitOps); PostgreSQL on Longhorn, DR-critical +
break-glass; hardened public exposure. Plex/Seerr use Plex auth; Minecraft N/A.
- Requirements R-IDP-01..06; ServiceDefinition gains an block.
- Onboarded early (with Gitea) so services adopt SSO as they come up.
- Threaded through: docs 00,01,07,10,12,13; roadmap phases+workstreams;
task board (T-6.1c/T-6.1d); glossary; ADR index; README.
