- IP geo-lookup via ip-api.com on register/heartbeat (country_code, city) - heartbeat_count column + uptime_pct computation on every heartbeat - Deduplication: register returns existing token for same IP+port - Heartbeat no longer overwrites registered IP (prevents IPv6 churn conflicts) - Migration 023: heartbeat_count column + backfill existing nodes
