## Review Lens
{{call.id}}
- If your call ID ends in _a: correctness and regressions first.
- If your call ID ends in _b: security and performance first.
- If your call ID ends in _c: readability, maintainability, and tests first.

## Instructions
Analyze the code changes above. Identify blocking issues and non-blocking suggestions. Score each rubric dimension 0-100.
- Suggest specific tests to add or update based on the changes.
- Return exactly one JSON object matching the schema below.
- Do not wrap the JSON in markdown fences.
- Do not output prose before or after the JSON.
- Use empty arrays instead of placeholder strings.
- If the exact line is unknown, omit the line field entirely. Never use placeholder values like 0.
- 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.

Return a single valid JSON object. Be thorough within the fields; brevity is not a goal. Match this schema:
{
  "summary": "Brief review summary",
  "blocking_issues": [{"file": "path", "severity": "critical|high|medium", "description": "issue", "suggestion": "fix"}],
  "non_blocking_suggestions": [{"file": "path", "category": "style|naming|docs", "description": "suggestion"}],
  "rubric_scores": {"correctness": 0, "security": 0, "performance": 0, "readability": 0, "test_coverage": 0, "api_stability": 0},
  "overall_score_100": 0,
