Freight Container Milestone Tracking: ETA Evidence from Port to Delivery

Freight container milestone tracking aggregates available carrier, vessel, port, partner, and operator records into a source-labeled timeline tied to one shipment or container. AIS observations describe a vessel rather than proving a container's physical location or customs status; ETA evidence, customs updates, and drayage handoffs remain separately sourced records.

• Milestone evidence Retain the source and timestamp for carrier, vessel, port, partner, and operator records tied to the shipment or container.
• Source freshness Show each ETA's source and observation time, retain prior values, and verify separately sourced customs and drayage updates before acting.
