jmurarka/SakshyaChain ? reverse-engineered prompt

Build me a full stack app called SākshyaChain for legal and investigation teams, with a clean React front end and an Express backend, set up so it runs easily in Docker.

I want two main areas, one for senior oversight and one for investigators. The senior view should let an admin see users, review audit history, view security alerts, and verify digitally signed evidence. The investigator view should let people manage cases, upload evidence, and work inside a restricted workspace with only the access they are allowed to have.

Please make it feel like a secure digital vault, with login, MFA style verification, role based access, audit logs, and emergency break glass access for rare situations. The app should support multi tenant style separation, and evidence should feel protected with encryption and chain of custody tracking. Add a simple API health check, sensible default pages, and enough UI polish that it looks like an enterprise internal tool. If you need current docs or best practices for anything, look them up online first.
