cthleen/fp-rsbp ? reverse-engineered prompt

Build me a Python app that helps a user upload or manage some data, send it through an LLM powered workflow, store and retrieve it from a database and a vector search system, and show the results in a simple web UI.

I want it to feel like a complete end to end pipeline, with clear entry points to run the app, configure it from an env file, and keep the code organized into sensible parts for auth, data handling, database access, formatting, evaluation, and any explanation or insight features. If you need to check current docs for any libraries, go ahead and look them up online.

Please make it usable from the start, with sensible defaults, a basic interface, and enough structure that I can extend it later without rewriting everything.
