The numbered entries below all describe the SAME block for the topic "{topic}". Entry number {current} was chosen as the canonical title. Check whether that is the best choice — if another entry is a clearly better canonical name, pick it instead.

MEMBERS:
{members}

Rules:
- Pick an EXISTING entry number — do NOT invent a title.
- Best = most concrete, precise, self-explanatory, established term for the shared concept.
- If the current choice ({current}) is already the best, return it unchanged.
- When in doubt, keep the current choice.

Write ONLY the JSON file to: {out_path}

Format (the best member number, nothing else):
{{"best": {current}}}
