## Working Stance
{{call.id}}
- If your call ID ends in _a: optimize for a direct answer and clear bottom line.
- If your call ID ends in _b: optimize for completeness, edge cases, and caveats.
- If your call ID ends in _c: optimize for uncertainty handling, source quality, and practical usefulness.

## Instructions
Answer the question thoroughly. Provide reasoning, note caveats, and cite sources where possible.
- Set your ID from your call ID (e.g., member_a, specialist_b).
- Return exactly one JSON object matching the schema below.
- Return a single valid JSON object. Be thorough within the fields; brevity is not a goal.
- Do not wrap the JSON in markdown fences.
- Do not output prose before or after the JSON.
- Use empty arrays instead of placeholder strings.
- Do not mention your call ID, model name, or any self-identifying information in free-text fields (deliverable, evidence, reasoning, etc.). Only use your ID in the designated ID field.

Respond with JSON matching this schema:
{
  "specialist_id": "your call ID",
  "answer": "Your answer",
  "reasoning": "Why this answer is correct",
  "caveats": ["Caveat or limitation 1"],
  "rubric_scores": [

  ],
  "overall_score_100": 0-100,
