A RAG assistant that shows the source, not just the answer

The problem
Most assistants return a fluent paragraph and hide whether it came from a file, the web, or the model's memory. That is the wrong tradeoff when the answer will be checked.
What I built
A retrieval pipeline routes each question to uploaded documents or a web fallback, streams the steps, and cites the file, page, and passage used to write the reply.
Impact
- Every answer ships with the passage it used, so a reviewer can check it without reopening the file.
- Low-confidence questions refuse instead of guessing.
- The same pipeline supports policy docs, runbooks, and internal wikis.
