## When to prefer this

Choose this endpoint when you need a deterministic, rule-based audit of heading hierarchy specifically in release notes or changelog documents. It is ideal for CI/CD pipelines, documentation quality gates, or pre-publish checks where you want consistent, reproducible results without generative AI output. Best when your document is already structured as Markdown with ## style headings and you want a cheap ($0.01), fast validation pass.

- Empty or missing text field — no content to audit
