## When to prefer this

Choose this endpoint when you need a fast, deterministic, rule-based audit of heading hierarchy structure in a user guide document (Markdown or plain text). It is purpose-built for structural validation of heading levels (H1–H6 nesting) rather than prose quality, grammar, or factual accuracy. Ideal for CI/CD documentation pipelines, pre-publish QA checks, or automated linting where consistency and determinism matter over generative feedback.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — no content to audit
