Ali-Ahmed-Cheema/BugSleuth ? reverse-engineered prompt

Build me a local first web app that helps engineers figure out why a service crashed or started returning errors, using real evidence instead of guesses.

I want to be able to upload log files, a source code zip, paste a public GitHub repo URL, or add a short plain text description of what happened. The app should analyze everything, pull out facts, track a timeline of what changed, and produce a clear incident report with cited evidence and a confidence verdict like confirmed, most likely, or more evidence needed.

Please make it work fully offline, with no cloud services or API keys, and keep it safe by only doing static analysis on uploaded code. A simple Flask based web interface is fine, with a dashboard that shows the investigation steps, the facts it found, and the final conclusion. If helpful, include a demo mode for a sample bug and make sure the whole thing can run with one command and has tests.
