Anomaly detected on ${deviceId}: trust score ${score.toFixed

Error message

Anomaly detected on ${deviceId}: trust score ${score.toFixed(3)}

What it means

Not a thrown error but a warning emitted by the AnomalyScanWorker callback during initialize(): the periodic anomaly scan computed a trust score for a device that fell below the anomaly threshold, signaling potentially compromised or misbehaving IoT telemetry. It fires whenever a scheduled scan flags a device.

Solutions

1. Investigate the named device; a low trust score indicates anomalous behavior that may require isolation or firmware checks.
