# SaaS architecture when code is cheap

## 16. What would show this wrong

- Grammar coverage stalls. If most screens or configurations in a real product cannot be expressed without per-case grammar extensions, the fixed cost never amortises and the horizontal route was correct.
- Semantic error survives validation. More than 10% of validator-passing documents turn out semantically wrong in production, and review load stays proportional to output volume.
- The case corpus proves impractical to build, leaving verification dependent on reading. This is the failure mode with the strongest historical precedent.
