The numbered entries below all describe the SAME block for the topic "{topic}".

CURRENT TITLE: {current_title}

MEMBERS:
{members}

Check whether the current title is the best canonical name for this block.

Rules:
- Current title good (concrete, precise, self-explanatory, no reference/placeholder like "Satz 7.18") → confirm it.
- Otherwise pick the best member ("best" REQUIRED) and optionally propose a SHORTER name: max 8 words, ONLY terms that appear in the members, exactly as concrete as the shared content — never a broader umbrella term, never a textbook concept the members don't mention. NO catalog/reference brackets ("(Satz 6.33)"); a known acronym in brackets ("(VC)") is fine.
- A source numbering is never a canonical title, even with a name attached ("Satz 7.13 (Christofides)", "Satz 7.6: Kriterium …") → treat such a current title as NOT good and rename to the concept/result; the numbering belongs in the description.
- When in doubt, confirm the current title.
