"""Documents (RAG): an uploaded file is chunked, indexed and then listed.

This is the one area whose dependency is not satisfiable from a clean
checkout. `requirements.txt` pins `chromadb-client`, the HTTP client;
the ChromaDB *server* is a separate install, and without one reachable
the app returns a deliberate 503 from the upload route rather than
indexing into nothing. So the scenario skips with that reason printed in
the table instead of being quietly dropped - a row saying SKIP and why
is the honest report, and it goes green as soon as a vector service is
there.
