Problem

We insure over 300 million devices and process tens of thousands of insurance claims per day. When a customer files a claim for a lost or broken phone, we ship a replacement within hours - but that means our fraud detection must complete before the device ships, not after. Our current warehouse is a nightly batch job and the fraud team is working from yesterday's data. Design a pipeline that supports real-time fraud scoring at claim submission time.

Summary

The claim looks clean. The fraud model disagrees.
