Harbormaster: Evidence-Gated, Replay-Safe Maritime Anomaly Detection on AWS
Harbormaster is a system designed to detect untrusted AIS vessel reports by combining fast physics checks with a heavy machine learning model. It ensures alerts are attributable and recoverable through replay-safe change data capture, evidence-gated model promotion, and scale-to-zero serving on AWS. This addresses the challenge of processing unreliable maritime data reliably.
