Matheusmatos2916/denialflow_ai ? reverse-engineered prompt

Build me a web app for healthcare claim denial management that lets a user sign up, log in, upload a CSV of denied claims, and then run an AI workflow that classifies each denial, ranks which claims are worth fighting first, looks up supporting documents, and drafts an appeal letter.

I want a clean dashboard where I can see uploaded batches, workflow runs, individual claims, and appeal review. The appeal review screen should show the draft, the source documents used, and let a human approve, edit, or reject the appeal before it is finalized. It should also show helpful business metrics like how many claims were processed, how many are pending review, and the potential dollar amount recovered.

Use demo data only, not real patient data. Keep the app modern and simple to use, with a React frontend and a FastAPI backend, and make sure the workflow can run in the background. If you need to check current docs for any library, go ahead and look them up online.
