Most RAG blog posts read like product brochures. After building a few systems over the last months and reading way too many production post-mortems, I'm pretty convinced the LLM is usually not the thing that breaks first.

Especially not in EU mid-market deployments.

A few failure modes I see again and again:

1. Retrieval quality falls apart somewhere between 10K and 40K docs

The demo with 500 PDFs looks amazing.
