Why Does AI Code Pass Tests But Fail Under Real Load?

AI generated code is optimized to satisfy the test, not to survive production. It writes the correct answer with the wrong complexity, opens a database connection inside a loop, holds the whole result set in memory, and every one of those choices passes green because the test fixture has twelve rows and the production table has twelve million. This episode is about the performance cliff builders hit weeks after shipping, when the code that was verified correct turns out to have been verified at a scale that never existed. Produced by VoxCrea.AI This episode is part of an ongoing series on governing AI-assisted coding using Claude Code. 👉 Each episode has a companion article — breaking down the key ideas in a clearer, more structured way.
