The docs-fact census wave re-read the live hosts and re-keyed every page it could: runtime/payload identities, ports, sizes, ledger figures, unit state, and the retirement banners that drifted as the fleet moved. The wave was interrupted mid-run, so this commit carries only what passed the integrity gates: every touched page parses (front matter or H1+status convention intact, balanced fences, no truncated tables, trailing newline), the docs_completeness and link-integrity seams are green, and bats is 384/384. Numbers that this session proved on live hosts are keyed to the measured value, not the page's earlier claim.

Network Architecture
One Caddy fronts both hosts. It runs as a container on Dankclaw (192.168.0.143) and terminates TLS for every service on the LAN. Pi-hole on Dankclaw answers the service names for LAN clients; Porkbun answers them for the WAN. The G36 router firewall governs external access. SearXNG outbound traffic exits through the Gluetun VPN container.
Topology
As of 2026-08-28 the front door is a two-tier chain: Caddy terminates TLS,
Anubis verifies the client (DENY known AI scrapers, CHALLENGE everyone
else), and accepted traffic returns to Caddy's internal listener on :8016,
which proxies every request whole to the Authentik server with the Host
header preserved; Authentik's embedded outpost routes on that Host against
each proxy provider's external_host, serves the login flow in place for
sessionless clients, and forwards authenticated traffic back to Caddy's
post-auth listener :8017, where per-vhost routing reaches the app. See
Anubis and Authentik.

Guarded (Anubis :8923 → Caddy :8016 → Authentik outpost → Caddy :8017):
homepage (www.), search, grafana (dankclaw/Caddyfile:128-129),
prometheus (:135-137), loki (:141-143), seerr (:148-150), marreta
(:155-160), romm (:167-169), files (:172-174). Exempt / own-auth: auth.
(the IdP login itself), ai. (OpenWebUI, its own OIDC), gitea (git smart-HTTP
clients cannot solve JS challenges — /info/refs and git-*-pack pass
unchallenged), pihole (Caddy basicauth, :167), plex (plain HTTP),
books/jellyfrank (own logins), hermes./hermesadmin., and the *arr vhosts
that terminate on FrankBook-Pro (:254-281, "exempt by construction: own
auth"). Grafana is not exempt even though it signs in through authentik as
an OAuth2 relying party (:123) — the chain wraps it too. sonarr. has no
vhost at all (LAN 192.168.0.112:8989 only, :265-267).
Dankserver runs no proxy of its own. Its services expose published LAN ports, and the Dankclaw Caddy routes the names to those ports.
Hostnames
| Scope | Convention | Resolved by |
|---|---|---|
| LAN | romm.franksdank.cloud → 192.168.0.143 |
Pi-hole (addn-hosts) |
| WAN | romm.franksdank.cloud → 71.227.227.172 |
Porkbun A record |
Users type a name and nothing else. Caddy maps the name to the upstream. The
split between the two resolvers removes the need for router NAT loopback.
Verified 2026-10-18: dig +short @192.168.0.143 romm.franksdank.cloud →
192.168.0.143, and a public resolver returns 71.227.227.172 for the same name.
See LAN-DNS for the flow and the router hand-off.
TLS
Caddy holds one Let's Encrypt certificate per vhost, issued and renewed through the DNS-01 challenge via the Porkbun module. No inbound port 80/443 is required. Details in Caddy.
Gluetun Path (SearXNG + Marreta)
gluetun.container and searxng-valkey.container set
Network=searxng.network (runtime network systemd-searxng), while
searxng.container, marreta.container and marreta-browser.container join
the tunnel the modern way — Network=gluetun.container
(dankclaw/searxng/quadlet/searxng.container:18,
dankclaw/marreta/quadlet/marreta.container:34,
dankclaw/marreta/quadlet/marreta-browser.container:25), the Quadlet
equivalent of the retired compose network_mode: service:gluetun. Five
containers share the VPN exit, not three, and Marreta's outbound fetches leave
through the same WireGuard tunnel as SearXNG's. Pi-hole is a different kind of
exception (Network=slirp4netns, dankclaw/pihole/quadlet/pihole.container);
everything else on Dankclaw uses the normal LAN route. This matches KB Pattern
2 in Gluetun.
See Container Network Namespaces for which addresses are reachable from that
namespace (none of the unpublished host-netns listeners).
Access Policy
- The G36 router firewall governs what the WAN can reach. Port forwards are manual router steps; the repo tracks no router state.
- Access is layered: Anubis challenges/denies bots at the front door, then Authentik's embedded outpost (whole-request proxy, routed by
Host→ providerexternal_host) gates the wrapped apps — one proxy provider per guarded host is mandatory, and Anubis exempts the/outpost.goauthentik.io/*transport paths so login can happen before a challenge cookie exists. Apps with their own login (Grafana, Gitea, Plex) run unwrapped. See Anubis and Authentik. - LAN subnet:
192.168.0.0/24.
