01/Overview

What's in the book

Most guardrails are built to pass an audit, not to prevent harm. This deep dive distinguishes the two: where input and output filtering earns its latency, where it is theater, and how to constrain a probabilistic system without making it useless.

Safety theater blocks the demo and misses the risk. Building constraints that protect users without strangling the product.
