## When to prefer this

Choose this endpoint when you need deterministic, rule-based extraction of action-marker lines (e.g. TODO items) from a course outline document. It is ideal when you want consistent, repeatable output without generative inference or hallucination risk. Prefer it over LLM-based extraction when auditability and exact matching of flagged lines is required.
