# Overview

For complex work in regulated sectors, prompt-to-code cannot pass an audit. Making the specification the contract an AI must fulfil can, provided the spec stays anchored to the code and machines check conformance.[^s1]

# What it covers

- Why prompt-to-code fails the audit test
- What changes in the lifecycle
- The honest critique
- Spec-anchored, not spec-as-source
- Why spec programs decay
- Make conformance mechanical

# Bottom line

Make the spec the contract, keep it anchored to the code, and let machines prove conformance. That is the balance regulated industries need between innovation and control.

Governance has to become something that executes in the pipeline and in the agent's context.

Verification, trusted context and human judgment are now the scarce resources, and teams that redesign their lifecycle around them will pull away from teams that only add assistants.
