HarborGauge is a GenLayer cargo custody and cold-chain release protocol for manifests, seal checks, reefer readings, inspections, disputes and final release.
Terminal operators attach cargo documents and custody readings, run GenLayer inspection over the evidence, then clear, dispute, escalate or release a manifest with an audit trail.
