Dead Code Is More Dangerous Than Broken Code — How a Non-Homologous AI Caught the Blind Spot the AI Itself Had Rubber-Stamped
Description and use
<h2> Dead Code Is More Dangerous Than Broken Code </h2> <h2> The opening: an AI confidently told me to reuse a capability that didn't exist </h2> <p>Here's how it started.</p> <p>I was adding a small feature to my own coffee e-commerce store: let a customer pick a fresh combination of beans over chat, price it on the spot, and order it. The chat-ordering bot was already built — I'd even tested balance deduction on a real device. All I needed was one more piece: something on the backend to compute the price, because the amount can't be whatever the phone says it is.</p> <p>I handed the repo to
