Adds platform/cloudflared: a locally-managed tunnel whose ingress rules live in git. LAN/VPN-only hosts (plex, plex-vip, jackett, pihole, pihole-dns, semaphore, qbittorrent, radarr, sonarr, headlamp, unifi, crafty-mc) map to 404. The apex and *.home go to cilium-gateway-shared.gateway over TLS with matchSNItoHost. Last comes a catch-all 404. Nothing routes to the Kubernetes API. - 2-replica Deployment, hard node spread, non-root, pinned digest, PDB - default-deny plus an egress CNP: Cloudflare edge 7844/443, the Gateway, and Gateway backends by gateway-access=shared minus the LAN-only namespaces (needed because of the CVE-2025-30162 L7LB egress re-check) - PodMonitor plus two alerts that fire on absent series, with promtool tests - its own Flux Kustomization (dependsOn platform-config, wait:false, nothing depends on it), plus SOPS decryption patches in both overlays - placeholder credentials (SOPS-encrypted) so it can merge before enrolment - L0 cloudflared-ingress-rules, and a cloudflared_ scrape owner - runbooks/cloudflare-tunnel.md and decisions/2026-11-08-cloudflare-tunnel.md Co-Authored-By: Claude Opus 5.5 <[email protected]>

# Ready until the operator enrols the tunnel, and in a gating tier that would stall every app wave.
