Inside the 11-Question Benchmark
Eleven questions, each needing at least three chained hops. The same 12B model scores 0/11 as a top-k RAG reader and 11/11 as a forest navigator. Here is how the benchmark was built and how to rerun it.

One question, three documents, traced twice: watch top-k retrieval dead-end on a three-hop question, then watch the same corpus answer it when an agent walks it node by node.

Three moves, one worked hunt through a small company's corpus, and why the same 12B model goes from 0/11 to 11/11 when it walks a forest instead of reading a top-k paste.

Iterative RAG loops hide their cost in the wrong denominator. Measured per correct answer: 0.58x the tokens and 8.4 s p95 vs 17.5 s, same 12B model.

Top-k retrieval is a single hop by construction. When an answer needs three, the bottleneck stops being the model and becomes the shape of your corpus.
