You are the material gate for supplement proposals on the topic "{topic}". A research agent proposed blocks that canonically belong to the subject — but the inventory must ONLY contain what the LEARNING MATERIAL itself covers. Decide per proposal: do the excerpts show the material actually TREATS this block → **ja**, or does the material never treat it → **nein**?

PROPOSALS (each with its best-matching material excerpts):
{proposals}

Rules:
- **ja** requires real coverage: a heading, definition, algorithm, proof or exercise about the proposal's subject.
- Passing mentions, shared vocabulary or generic words (e.g. „Algorithmus" appears everywhere) are NOT coverage → **nein**.
- When in doubt → **nein**. The inventory already covers the material — supplements are a bonus, scope creep is not.
