+# felhom-op operator sudoers (TASK H1) — install as /etc/sudoers.d/felhom-op (0440 root:root).
+#
+# The DEFAULT operator identity (login via felhom-sshd only; key in /etc/felhom-sshd/authorized_keys/
+# felhom-op, outside ~/.ssh, so the customer's sshd never honours it [SF-3]). felhom-op is a normal
+# login user with NO ambient privilege — it escalates ONLY through these explicit repair verbs, so a
+# leaked operator key's blast radius is this verb set, not the box (locked decision §6). Deep repairs
+# that genuinely need root (pct, deeper systemctl) remain available via `root` as a tunnel-gated
+# break-glass account (PermitRootLogin prohibit-password on felhom-sshd), but the day-to-day identity
+# is felhom-op.
