+**Error logging (mandatory):** on a GENUINE functional failure (controller/SSH login or connect fail,
+unexpected REST/pfSense error, php fatal), the scripts log it via `.claude/scripts/log-skill-error.sh`
+before surfacing — do NOT log handled conditions (missing cred, bad args, site-not-found, "no results").
+The live scripts (`pfsense-ssh.sh`, `gw-control.sh`, `gw-audit.sh`) self-log; if you add a new script,
+do the same at its failure branches.

 Config changes are automated across many APs (no per-AP UI clicking) via the controller REST API
