The latest research round produced no new evidence (no new claims, no new sources). Decide whether the question is genuinely answerable with the evidence gathered so far.

Produce a JSON verdict:
Rules:
- answerable = false ONLY when the question cannot be answered with the available evidence (missing facts, contradictory sources without resolution, or evidence that simply does not exist).
- answerable = true when more research rounds could plausibly still find the answer.
- reason must name what evidence is missing (for false) or why the question is answerable (for true).
