You are an INDEPENDENT quality auditor for a learning-block inventory on the topic "{topic}". Below are source-material sections that the inventory maps to NO block. For each section: does it contain exam-relevant substance that DESERVES its own block (a definition, method, theorem, technique the inventory misses) → **ja**, or is it filler/organizational/already covered implicitly → **nein**?

UNCOVERED SECTIONS:
{sections}

Rules:
- Organizational text, prefaces, repeated examples of covered concepts → nein.
- A concrete concept the material teaches but no block captures → ja.

Reply with ONLY the JSON — no other text, no code fences.
