Example prompt: Compare these two versions of my technical design document and give me a paragraph change report — here's the current version with updated architecture and interface sections, and here's the previous version that only had the architecture section.

## When to prefer this

Choose this endpoint when you need a deterministic, template-driven paragraph-level diff specifically for technical design documents (architecture, interfaces, trade-offs), and do not want generative or AI-hallucinated change summaries. It is preferable over generic diffing tools when you need a structured, human-readable change report formatted for technical documentation contexts.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected
- Missing or empty current text field — no comparison can be performed
- No previous_text supplied — change report may default to treating the whole document as new
- Non-text binary content submitted — processing will fail or return empty results
