+- _check_domain_health_fast with loopback resolution.
+- _evaluate_domain_checklist with loopback override — no false dns_mismatch.

+
+# ── Server-local domain loopback overrides ────────────────────────────────────
+#
+# Some routers (especially newer ISP-provided devices) do not support NAT
+# loopback (hairpin NAT).  When a request originates on this computer and
+# targets a public domain name that resolves to the router's WAN address, the
+# router may refuse to loop the connection back in — causing Nextcloud, WordPress
+# background jobs, and other server-side callbacks to fail even when the service
+# is fully operational from the internet.
+#
+# This module installs a one-shot systemd service,
+# ``sovran-hosts-update.service``, that reads the configured service domains
+# from ``/var/lib/domains/`` at boot (and whenever triggered by the Hub after a
+# domain is saved) and writes ``127.0.0.1`` entries for them into a dedicated
+# Sovran-managed block in ``/etc/hosts``.
+#
+# With those entries in place:
+#   • Requests originating on this computer resolve the public domain name to
+#     127.0.0.1, reach Caddy directly, and never touch the router.
+#   • Caddy still receives the correct public hostname via TLS SNI so virtual-
+#     host routing and certificate validation continue to work.
+#   • The Sovran Hub can verify Caddy reachability locally without needing NAT
+#     loopback.
+#
+# Limitation: this does not help other devices on your home network (phones,
+# laptops).  Those devices resolve domains via the router's DNS and still depend
+# on NAT loopback (or require manual router DNS overrides).  For now, only
+# server-originated requests benefit from this override.
+#
+# On NixOS, /etc/hosts is normally a symlink into the Nix store and is
+# regenerated by the system activation script.  The ``system.activationScripts``
+# hook below converts it to a writable file each time the system is activated
+# (i.e. after every ``nixos-rebuild switch``) and then injects the Sovran block.
+# The same script is also run by the ``sovran-hosts-update.service`` unit so
+# that the Hub can trigger it immediately after saving a domain without
+# requiring a full rebuild.
