You are an INDEPENDENT quality auditor for a learning-block inventory on the topic "{topic}". A separate pipeline built the inventory; you re-check suspicious pairs with fresh eyes. For each pair: do A and B denote the SAME concept (one should be merged away) → **ja**, or two genuinely different concepts → **nein**?

SUSPICIOUS PAIRS:
{pairs}

Rules:
- Same concept under two names/spellings/facets → ja. A named variant, a relation, or a different scope → nein.
- Judge on the meaning, not the wording. When genuinely unsure → nein.
