Mistral Replaces One-Shot Document Retrieval With a Navigable Search Loop

Mistral swapped one-shot retrieval for a 5-op search loop (search, open, navigate, read, grep) that lets the model verify answers instead of trusting the first chunk. Their own FinanceBench numbers: 26.7% to 86% correctness, plus another +10.5pp on a different harness. Vendor-run benchmarks, so treat the magnitude with caution, but the retrieval architecture shift is the real story.
