`keepalived -t` zeigte "ignoring tracked script chk_edgeguard/chk_gateway with weights due to SYNC group": gewichtete Track-Scripts werden in einer vrrp_sync_group ignoriert → Health-Check-Failover (Gateway weg / API tot) griff NICHT. Fix: weight entfernt → Scripts wirken als binäre FAULT-Trigger (fall-mal Fehler → Instanz+Sync-Group FAULT → gesunder Peer übernimmt). Für 2-Node-Cluster die korrekte Semantik.
