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.

Operator turned off ExpressVPN auto-renew and purchased PIA. The single-shared-
gateway model is retained; provider/client/protocol change to PIA via Gluetun
over WireGuard with native port forwarding (qbittorrent-natmap port-sync).
Simpler than ExpressVPN: no custom OpenVPN config, just PIA user/pass
SOPS-encrypted; Gluetun provides the built-in kill-switch.
Updated: ADR-0013 (new) + ADR-0012 superseded + index; docs 00,01,03,07;
task board (T-3.2p/T-3.2, OQ-3).

Operator chose Option A. cert-manager solves ACME DNS-01 and ExternalDNS
manages *.home.keithjackson.dev records via a scoped Cloudflare token
(Zone.DNS.Edit, keithjackson.dev), stored SOPS-encrypted. Operator provides
the token once (new prereq T-2.4p); T-2.4/T-2.5 unblocked. Only OQ-BKP
(off-cluster DR backup target, Phase 4) remains open.
Updated: docs 00,08,09; task board.

Operator answers folded into the specs:
- OQ-3 VPN: ExpressVPN, cluster-controlled SINGLE shared in-cluster tunnel
(OpenVPN UDP / non-TCP), rules enforced outside the service. New ADR-0012
supersedes ADR-0008 (Gluetun-sidecar default dropped). Central kill-switch.
- OQ-1 WAN/edge: one commercial WAN, no multi-ISP plans; dumb SOHO edge (no
VLAN/VPN/services). Multi-WAN out of scope; segmentation + VPN in-cluster;
edge = NAT + manual port-forward. Gateway VIP resolved to Cilium L2
announcement. T-3.3 marked won't-do.
- OQ-2 storage: bulk media lives outside the cluster (backing TBD, non-blocking)
via a 'bulk' external-mount indirection; Plex metadata DB stays on Longhorn.
Split out a separate OQ-BKP for the off-cluster DR backup target (Phase 4).
- OQ-4 refined: wildcard record covers reachability but NOT ACME DNS-01 (needs
TXT-write access) and does not match *.home.* depth. Still OPEN: Cloudflare
API token (Option A) vs acme-dns delegation (Option B). T-2.4/T-2.5 blocked.
Updated: docs 00,01,03,04,08,09; ADR-0008/0012 + index; task board.
