I build the instruments AI systems are missing.

RAG World — a self-updating registry of retrieval-augmented generation technologies. Every maturity level is derived from collected evidence by a deterministic rule. No language model takes part, so the same evidence always yields the same level. Open data, CC BY 4.0, DOI 10.5281/zenodo.21943978.

Causa RAG — a diagnostic bench. It scores every question in a golden set separately, names the pipeline stage that failed, and compares two runs question by question, so the blast radius of a change is visible instead of assumed. Nothing leaves the machine it runs on. Citable at DOI 10.5281/zenodo.22117626.
