 The FINAL block inventory for the topic "{topic}" was assembled from several sources. Despite earlier filtering it can still carry duplicates: the same concept listed under two names. For EACH pair below, decide: do A and B denote the SAME block → **ja**, or TWO DIFFERENT blocks → **nein**?
 
+Decide on the underlying CONCEPT — from title and description — not on wording alone. Merge only when A and B are EQUIVALENT (the same statement, mutually interchangeable); a special case, a restriction, or one direction of a relation is NOT equivalent → **nein**.

 THE MOST COMMON ERROR is merging a named VARIANT with its base entity. A variant is NEVER its base: "3-X" ≠ "X", "Max-X" ≠ "Max-3-X", "Modified X" ≠ "X", "k-X" ≠ "X". A digit or qualifier prefix that restricts the entity makes it a DIFFERENT entity → **nein**.
