Essays on RAG infrastructure

A six-part series on RAG in production — what breaks at the registry, indexing and retrieval layers.

Data Registrar

Part 1

The layer where 80% of enterprise RAG quietly collapses: document registry, effective ACL, lineage and tombstones — through 9 events and 12 metrics.

RAG Indexer

Part 2

The layer where RAG becomes either useful or expensive: parsing, vision-first retrieval, chunking, embeddings, vector DBs, migrations and cost engineering.

RAG Retriever

Part 3

The 200–500 ms layer where RAG becomes a product or an incident: hybrid search, rerank, retrieval-time ACL, prompt-injection defense, golden sets, CAG vs RAG.
