Saiteja6529/claims-triage-platform ? reverse-engineered prompt

Build me an enterprise claims triage app for e commerce refund requests.

I want customers or support staff to submit a claim, have it processed asynchronously, and then get back a decision with a clear reason. The app should use a FastAPI API, a background worker for the long running work, and a simple database for storing claims and results. It should also include a retrieval based knowledge layer for policy lookup, a fraud or risk scoring step, and an OCR step for reading receipt images when they are uploaded.

If a claim looks valid and low risk, it should be able to trigger a refund through a Stripe sandbox style payment flow, otherwise it should mark it for review and explain why. Please make it easy to run locally with Docker too. Use the README as the guide, and look up current docs online if you need to fill in any gaps.
