Detects runaway loop-buying before the wallet drains: payment cadence anomaly detection, per-call and per-minute spend caps, consecutive-failure trip logic, circuit breaker states (closed, open, half-open), hard kill switch with evidence freeze, cooldown and resume rules, and a falsifier that stops the loop when the same data is reachable for
