+# felhom OOB belt — STATIC table (TASK H1). Installed by host-install; loaded on boot by
+# felhom-oob-nft.service. The agent mutates ONLY the two SETS (@operator_ips, @ssh_port) via the
+# narrow FELHOM_OOB sudoers — it NEVER touches the rules [trap 4], so the enforcement semantics are
+# fixed here and cannot be changed by the agent.
+#
+# Enforcement (scoped to iifname "wg-felhom" — the offsite tunnel — so :22 and every other interface
+# are UNTOUCHED [SF-3/OF-5]):
+#   - ESTABLISHED,RELATED replies always pass (covers the PBS path + reply traffic; PMTU-safe).
+#   - felhom-sshd's port is reachable from the operator /32 (in @operator_ips) over the tunnel ONLY.
+#   - any other tunnel source to that port is DROPPED at the host (defense-in-depth vs the endpoint).
+#   - the port is unreachable OFF the tunnel entirely.
+# Empty sets (before the agent's first sync) = the port rules match nothing = no enforcement yet
+# (felhom-sshd is not started until the agent renders its config either). priority -5 sits just above
+# the default; policy accept so this table only ever ADDS drops for the felhom-sshd port.
+#
+# Idempotent load: create-then-delete-then-define (a re-run/boot yields a clean table with EMPTY sets;
+# the agent refills them within one tick).
