dataelement/bisheng ? reverse-engineered prompt

Build me a self hosted web app for enterprise AI teams where people can create and manage LLM powered workflows, chat assistants, retrieval based knowledge apps, and multi step agents in one place.

I want a clean browser UI where users can log in, register, and then build flow based automations visually, with support for branching, loops, parallel steps, batch processing, and human review during execution. It should also let admins manage models, datasets, evaluations, fine tuning jobs, documents, and users with role based access control.

Please include strong document parsing for PDFs and office files, basic observability so I can see runs and usage, and the ability to run everything locally with Docker. Make it feel like an enterprise product, stable and polished, and if you need current implementation details, look up the latest docs online first.
