By storing requirements as structured, versioned data in systems like MongoDB, software can maintain a living connection to its original intent throughout its lifecycle. This approach enables systems to interpret documented purpose at runtime, validate behavior against intent, and maintain semantic alignment between what software does and what it was meant to do. When combined with AI for natural language compilation, RaC creates systems that don't just execute code but understand why they exist. ## Full article daily.dev links to this article rather than hosting it.
